Description

Technical Field

[0001] This utility model is a tool for disassembling and assembling the front suspension of a large mining truck. Background Technology

[0002] During production operations, the front suspension of some large mining trucks undergoes constant reciprocating motion due to bumps, which easily causes wear on the cylinder seals. Eventually, this can lead to internal leakage, affecting the vehicle's shock absorption. Therefore, regular disassembly and maintenance of the suspension are necessary. Disassembly and assembly account for over 70% of the total repair time and require at least five people to complete the work, making it time-consuming and labor-intensive. This is because the front suspension is heavy (weighing 350 kg), irregularly shaped, and top-heavy. Furthermore, its location under the truck cab restricts space for disassembly and assembly, preventing the use of the vehicle and necessitating multiple people to remove it. To address the difficulties in disassembling and assembling the front suspension of these trucks, improve maintenance efficiency, and enhance safety, developing a specialized disassembly and assembly tool is essential. Summary of the Invention

[0003] The purpose of this utility model is to address the above-mentioned problems by proposing a tool for disassembling and assembling the front suspension of a large mining truck, which enables the quick and safe disassembly or installation of the front suspension of a large mining truck, saving time and effort, ensuring safety, and improving work efficiency.

[0004] This utility model proposes a large mining truck front suspension disassembly and assembly tool, which has a pin, a bracket, and a hydraulic cylinder connecting plate. The bracket and the pin are a pair, with each pin vertically connected to a bracket. The pin is also connected to a hydraulic cylinder connecting plate. The two pins are symmetrically mounted on the left and right forks of the forklift for rotation. Two pairs of upper and lower jaws are symmetrically mounted on the two brackets to clamp the truck front suspension. The hydraulic cylinder connecting plate is connected to the forklift hydraulic cylinder to adjust the tilt of the bracket.

[0005] The bracket and the pin are provided with stiffening plates to increase the connection strength.

[0006] The forklift selected has forklifts with centering, translation, lifting and tilting functions to ensure that the left and right jaws can clamp and release and adjust the tilt angle.

[0007] The pin is connected to the upper or lower end of the bracket.

[0008] The pin is installed on the forklift fork arm using either a pin hole or a bearing.

[0009] The claw and the bracket are installed and connected by bolts or welding.

[0010] When the jaws are connected to the bracket by bolts, the bracket has multiple connection holes to adjust the distance between the upper and lower jaws.

[0011] The gripper's opening is semi-circular, and its radius is adapted to the circle of the front suspension part it grips.

[0012] The support frame is made of channel steel or steel plate.

[0013] This utility model is used as follows:

[0014] During disassembly, operate the forklift, bring the two forks close to the front suspension, and let the claws on both sides surround and clamp the front suspension. After removing the connecting bolts between the front suspension and the vehicle body of the large mining truck, slowly raise the forks to lift the front suspension away from the cylinder seat. Then, reverse to remove it and place it at the maintenance location.

[0015] When installation is required, start the forklift to clamp the front suspension to be installed, slowly approach the hydraulic cylinder seat of the truck and insert it into the seat. After tightening the connecting bolts, release the clamps and then reverse the forklift.

[0016] This utility model has a simple structure, flexible operation, and is easy to manufacture and install, making it easy to promote. It is convenient and quick to disassemble and install the front suspension of large mining trucks, saving time and effort, and is safe and reliable. Attached Figure Description

[0024] The present invention will be further described below with reference to the accompanying drawings.

[0025] like Figure 1-4As shown, the bracket 1 is made of channel steel or steel plate, with a connecting hole for the pin 5 at its lower or upper end. This connection is a fixed connection, usually welded, with stiffening plates 4 welded between the pin and the bracket.

[0026] The bracket has connecting bolt holes for the upper jaw 11 and the lower jaw 2. Multiple connecting bolt holes for the lower jaw are pre-drilled to adjust the distance h between the upper and lower jaws. Alternatively, these bolt holes can be made into a racetrack shape for easy adjustment.

[0027] One end of the hydraulic cylinder connecting plate 10 is welded and fixed to the pin shaft, and the other end is pin-connected to the forklift hydraulic cylinder 6.

[0028] The pin is mounted on the forklift fork arm and rotates through the pin hole. A shaft baffle 9 is provided on the outside of the pin hole to prevent the pin from shifting.

[0029] As described above, the forklift is selected with fork arms that have translation, lifting and tilting functions to meet the requirements of this utility model.

[0030] Components and designations not mentioned are as described above.

[0031] The applicant company uses large mining trucks of a well-known brand for coal and slag mining operations. In order to ensure the normal operation of the vehicles, the front suspension of the trucks needs to be inspected regularly or irregularly. Previously, the disassembly and assembly of the front suspension was done entirely by manpower. During the repair of the front suspension, the time spent on disassembly and assembly accounted for more than 70% of the total maintenance time, and at least 5 people were needed to complete the work, which was time-consuming and labor-intensive.

[0032] Significant results have been achieved after adopting this utility model, specifically:

[0033] Save time

[0034] By comparing the disassembly and assembly times before and after the improvement, the total disassembly and assembly time using this utility model is reduced by more than 50%, greatly improving maintenance efficiency.

[0035] Effortless

[0036] Previously, it took more than 5 maintenance personnel to disassemble and assemble the front suspension of a large truck. With this new invention, only 1 forklift driver and 2 operators / commanders, a total of 3 operators, are needed to complete the disassembly and assembly of the suspension.

[0037] Safety

[0038] The clamping force is provided by the forklift's hydraulic system to prevent tipping due to bumps during pushing, thus ensuring safe operation during disassembly and assembly.
