"The broken hammer is weak, the wood grabber is loose, the breakthrough point saw cutting card... These seemingly common failures are actually mostly due to improper use and operation or lack of maintenance." Recently, in response to the high-frequency failure of hydraulic attachments on the project site, Qin Jia Technology combined with the practical experience of engineering enterprises in its service area to officially release the "Practical Operation Guide for the Use and Maintenance of Hydraulic Attachments" (hereinafter referred to as the "Guide"), systematically combing the use specifications, maintenance points and common problem solutions of the three core products of broken hammer, wood grabber and breakthrough point saw, providing professional reference for front-line construction personnel.
Analysis of the core pain points of the three attachments, directly addressing the high-frequency problems of construction
According to the statistics of the technical service team of Qin Jia Technology, more than 60% of the hydraulic attachments failures in the regional engineering enterprises served in the past year were related to use and maintenance. The "Guide" focuses on the disassembly and explanation of the typical problems of the three attachments.
As the "main equipment" of mining and demolition operations, breakers are most prone to problems such as attenuation of impact force and stuck drill rods. The "Guide" clearly states that "empty hitting" and "partial hitting" are the core incentives during construction - empty hitting will cause hard collisions between the piston and the cylinder block, shortening the service life by more than 30%; partial hitting is easy to cause bending and fracture of the drill rod. In addition, hydraulic oil pollution is also a common hidden danger. When the impurity content in the oil exceeds the standard, it will block the hydraulic valve group, causing unstable strike frequency.
In addition to the crushing hammer, the wood grabber often has operation and maintenance problems due to the complicated contact with materials during the material grabbing operation. Technicians found that many operators forcibly grab materials that exceed the rated load in pursuit of efficiency, resulting in deformation of the claw teeth and leakage of the hydraulic cylinder; and after grabbing sharp stone or steel, failure to clean up the residual debris between the claw teeth in time will cause uneven wear of the claw teeth in the long run and affect the grasping stability.
For breakthrough point saws, poor cutting and rapid wear of saw blades are the most reported problems by construction workers. The "Guide" particularly emphasizes that the selection of saw blades and material matching is the key - high-speed steel saw blades are used when cutting steel, and special alloy saw blades are used when cutting wood or concrete. Mismatch use will shorten the life of saw blades by 50%; at the same time, failure to maintain a uniform speed during the cutting process will cause the saw blade to overheat and anneal, resulting in "uncut" situation.
Customized maintenance plan, simple practical operation and easy landing
"For start-ups and small and medium-sized engineering teams, complex maintenance processes are difficult to implement, so our guide focuses on'simple, effective and cost-controllable '." According to the technical person in charge of Qin Jia Technology, the "Guide" has formulated a differentiated "daily + regular" maintenance plan for the three major accessories. All operations do not require professional equipment, and front-line personnel can perform simple training.
The core of the maintenance of the breaker lies in the hydraulic system and lubrication: check the hydraulic oil level and oil temperature before daily operation, replenish the same type of hydraulic oil in time when it is lower than the standard line, and stop the machine for cooling when the oil temperature exceeds 60 ° C; add grease to the connection between the drill rod and the bushing every week to avoid dry friction and wear. In terms of regular maintenance, it is recommended to check the seals every 500 hours of work, find oil leakage and replace it in time, and replace the hydraulic filter every 1000 hours to prevent impurity circulation.
The maintenance of the wood grabber focuses on the claw teeth and hydraulic components: after each operation, use a high-pressure water gun to clean the soil and gravel between the claw teeth, and correct the deformed claw teeth in time; check the hydraulic pipeline joints before daily operation, and tighten the sealing ring if there is oil leakage; lubricate the claw tooth pin every month to prevent rust from getting stuck. For the scenario of frequent grasping of corrosive materials, the "Guide" specifically recommends increasing the frequency of rust prevention treatment to prolong the service life.
The maintenance of the breakthrough point saw revolves around the saw blade and the power system: after each use, the saw blade needs to be disassembled, the residual material between the saw teeth needs to be cleaned, and the surface of the saw blade needs to be wiped with anti-rust oil; daily inspection of the tightness of the saw blade, too loose can easily lead to cutting deflection, too tight will increase the motor load; check the transmission belt every 300 hours, and replace it in time if there is a crack or slack to avoid breakage.
Practical case + free Q & A, small details reduce operation and maintenance costs
In order to make the "Guide" more practical, Qin Jia Technology also included three typical troubleshooting cases in it. For example, the breaker of a mine construction team was "weak", and the technicians found that it was not a component damage, but a long-term failure to replace the hydraulic oil filter element, resulting in insufficient oil pressure. After replacing the filter element and cleaning the valve group, the equipment immediately returned to normal, saving nearly 10,000 yuan compared to replacing the parts.
"For small and medium-sized engineering enterprises, the cost of equipment operation and maintenance directly affects the construction efficiency." The founder of ANGMUKE Technology said that the "Guide" released this time has been freely downloaded through the company's official website and WeChat official account. At the same time, a "technical Q & A line" has been opened to arrange senior engineers to provide customers with one-to-one fault consultation services. In the next step, the company will also carry out offline practical training for regional customers to help operators master maintenance skills and reduce the incidence of equipment failures through "theory + live demonstrations".
Industry insiders say that start-ups focus on customer operation and maintenance pain points to provide value-added services, which not only reflects technical professionalism, but also enhances customer stickiness. The release of the "Guide" not only provides practical tools for construction personnel, but also sets an example for the hydraulic accessories industry to attach importance to "use and maintenance services" in sub-sectors.
