Description

Technical Field

[0001] The invention relates to the technical field of maintenance of mining dump trucks, and in particular to a fender disassembly and assembly tool for a mining dump truck and a use method thereof. Background Art

[0002] Large mining dump trucks are mainly used for short-distance transportation of loose materials such as ore, rock, soil, sand and gravel in mines, construction sites and other places. They can carry several tons to tens of tons of materials to meet the heavy load requirements of mining operations.

[0003] In the busy operation scenes in mining areas, large-scale mining dump trucks are always in a high-intensity operation state. Since the working environment is mostly outdoors, the mudguards of mining dump trucks can prevent dirt such as mud and water stains from splashing onto the body and chassis components, while reducing the impact of gravel flying out from the wheels on the body chassis and engine structure, thereby protecting the vehicle from failure. Therefore, the working environment of the mudguard is very harsh, and manual maintenance and repair are often required. During this maintenance process, there are many problems that are difficult to solve.

[0004] On the one hand, the installation position of the fender of a large mining dump truck is relatively high, about 3 meters from the ground, and it is difficult for conventional working tools to reach it conveniently. In the process of workers climbing up to disassemble and assemble, the disassembly and assembly process is very strenuous due to the inappropriate tools, which increases the difficulty of the workers' disassembly and assembly operations; on the other hand, the fender of a large mining dump truck itself is very heavy, which can reach hundreds of pounds, and because of its specific inclination angle, it blocks the dirt, water stains and splashing stones. Traditional general disassembly and assembly tools cannot fit it tightly and stably, resulting in the lack of effective support tools for lifting the fender during the disassembly and installation process. Existing tools cannot achieve the lifting and fixing of the fender during the entire disassembly and assembly process, making the disassembly and assembly of the fender very difficult. The disassembly and assembly process is prone to damage to the working tools and the fender, and manual handling is also extremely strenuous. The entire operation process not only consumes a lot of time and manpower, but also has extremely low efficiency. There are also frequent safety hazards such as fender slipping and collision caused by loose fixation and uneven force. Summary of the invention

[0026] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0027] Since the fenders of large mining dump trucks are installed at a relatively high position, about 3 meters from the ground, conventional operating tools are difficult to reach conveniently. In addition, the disassembly and assembly process is very difficult due to the inappropriate tools used by operators during the disassembly and assembly process, which increases the difficulty of the disassembly and assembly operation for the operators.

[0028] In addition, the fender of a large mining dump truck has a large weight, which can reach hundreds of pounds. Because it has a specific tilt angle to block dirt, water stains and splashing stones, traditional general disassembly and assembly tools cannot fit it tightly and stably, resulting in the lack of effective support tools for operators to lift the fender during the disassembly and installation process. Existing tools cannot achieve the lifting and fixing of the fender during the entire disassembly and assembly process, making the disassembly and assembly of the fender very difficult. The disassembly and assembly process is prone to damage to the operating tools and fenders, and manual handling is also extremely laborious. The entire operation process not only consumes a lot of time and manpower, but also has extremely low efficiency. Safety hazards such as fender slippage and collision caused by loose fixation and uneven force also frequently occur. To this end, the present invention provides a fender disassembly and assembly tool for a mining dump truck and a method for use.

[0029] Example 1

[0030] In a typical embodiment of the present invention, Figure 1-Figure 3 As shown, a mudguard disassembly and assembly tool for a mining dump truck is proposed, comprising a base provided with a through hole 1, and the base can be mounted on the fork of a forklift through the through hole 1; a side upright plate 2 is provided on the top of the base, and a plurality of mounting holes are provided on the side upright plate 2, and a mounting tube 3 is provided in the plurality of mounting holes to protrude from the side upright plate 2, and a disc structure 4 is provided at one end of the mounting tube 3 close to the mudguard; and a fixing bolt 5 is also included, and a handle is provided at one end of the fixing bolt 5, and an end of the fixing bolt 5 away from the handle is arranged in the mounting tube 3, passes through the disc structure 4 and extends to the other side of the mudguard, a fixing nut 7 is provided to be connected with the fixing bolt 5 passing through the mudguard, and a gasket 6 is provided between the fixing nut 7 and the mudguard.

[0031] Furthermore, the base is configured as a rectangular structure, and a through hole 1 is provided along the length direction of the rectangular structure. The base can be mounted on the fork of a forklift through the through hole 1 .

[0032] In this embodiment, the overall structure of the disassembly and assembly tool is systematically optimized, and the actual working conditions of the fender are fully considered. The base is provided with a through hole 1 which is a special hole for forklifts. The hole size and position are precisely calculated, and can achieve accurate docking and positioning with the fork of the forklift, and the structure is stable. Relying on the powerful and flexibly controllable lifting power of the forklift, whether in a complex and narrow space or at a higher working height, the fixture and fender can be easily moved smoothly and accurately positioned, which fully meets the special needs of high-level operations in mining areas.

[0033] In addition, the fender is divided into a fender metal part 8 and a fender rubber part 9. It is understandable that the fender of a mining dump truck has a large weight, so a disassembly and assembly tool is required to assist in disassembly and assembly. The disassembly and assembly tool provided in this embodiment is mainly achieved by clamping and fixing with the metal part of the fender.

[0034] Furthermore, the side upright plate 2 is arranged perpendicularly to the top of the base along the length direction of the base, and the side surface of the side upright plate 2 and the end surface of the rectangular structure base close to the fender are arranged in the same plane.

[0035] Furthermore, a plurality of ribs are provided between the side panels 2 and the top of the base.

[0036] Furthermore, the plurality of ribs are arranged in a triangular structure.

[0037] In this embodiment, two triangular ribs are arranged between the side stand 2 and the top of the base, and such arrangement can enhance the structural strength of the entire disassembly and assembly tool.

[0038] Furthermore, the plurality of mounting holes are symmetrically arranged about a center line in the length direction of the side stand plate 2 .

[0039] Furthermore, the lengths of the mounting pipes 3 passing through the plurality of mounting holes are consistent.

[0040] Furthermore, the length of the mounting tube 3 located at the upper part of the side upright plate 2 protruding from the side upright plate 2 in the direction close to the fender is greater than the length of the mounting tube 3 located at the lower part of the side upright plate 2 protruding from the side upright plate 2 in the direction close to the fender.

[0041] In this embodiment, the side upright plate 2 of the disassembly and assembly tool is symmetrically arranged with two groups of bolt mounting holes, each group consisting of two mounting holes. A special iron pipe is embedded in the mounting hole as a mounting pipe 3, and the mounting pipe 3 is set to protrude from the side upright plate 2 by a length according to the inclination angle of the fender, so that the length of the upper mounting pipe 3 protruding to the left from the side upright plate 2 is greater than the length of the lower mounting pipe 3 protruding to the left from the side upright plate 2, so that the upper and lower mounting pipes 3 form an inclination angle adapted to the fender, so that when the disassembly and assembly tool is close to the fender, it is convenient to insert it from a narrow space, and it is convenient for subsequent installation operations, and the disc structure 4 can be closely attached to the surface of the fender.

[0042] In this embodiment, the disc structure 4 also includes a rubber structure layer and a metal structure layer. When the fixing bolt 5 is installed, the rubber layer of the disc structure 4 fits tightly to the surface of the fender, and evenly disperses the force of the fixing bolt 5 to ensure uniform and stable force. The disc structure 4 is made of high-strength and wear-resistant material, and its large surface area is in contact with the fender, just like applying "flexible support" to the fender, effectively dispersing local pressure, and avoiding deformation and damage of the fender due to excessive force on the single point of the fixing bolt 5.

[0043] Furthermore, the handle is configured as a square rounded handle, the fixing bolt 5 is provided with a thread at one end away from the square rounded handle, the gasket 6 comprises a rubber layer and a metal layer, and the rubber layer is in contact with the fender.

[0044] A square rounded handle is welded on the head of the fixing bolt 5, which is comfortable to hold. The operator can accurately control the strength and direction during the force application process. The operation is convenient and smooth, and the stability is strong; the disc structure 4 is abutted against the other side of the fender end and is equipped with a thick circular gasket 6. The gasket 6 is made of a composite material of a high friction coefficient rubber layer and a metal layer. The texture is tough and the elasticity is moderate. It tightly bites the surface of the fender, greatly improves the friction force, and significantly enhances the clamping stability, avoiding damage to the metal surface of the fender during the clamping process; the fixing nut 7 clamps the fender through threaded tightening. Even if it encounters severe vibration or external pulling, it can still ensure that the overall connection is securely fastened, thereby building a solid safety line for the entire process of fender disassembly and assembly.

[0045] In a second aspect of the present invention, a method for using a mining dump truck fender disassembly and assembly tool is provided, comprising:

[0046] Determine the vehicle side position of the fender to be removed from the mining dump truck, make the side of the side stand plate 2 of the disassembly tool with the disc structure 4 close to the fender, and put the base of the disassembly tool on the fork of the forklift through the through hole 1 and fix it. The forklift controls the fork to make the disassembly tool reach the specified disassembly position;

[0047] Make the multiple disc structures 4 on the side upright plate 2 abut against the surface of the fender, make the mounting holes on the mounting tube correspond to the connecting holes on the fender, pass the fixing bolts 5 through the mounting tube and the disc structure 4 and extend through the connecting holes to the other side of the fender, pass the fixing bolts 5 through one end of the fender to install the gasket 6, use the fixing nuts 7 to connect and fix the fixing bolts 5, clamp the fender between the disc structure 4 and the gasket 6 on the fixing bolts 5, and complete the installation of the fender and the disassembly and assembly tool;

[0048] Carry out disassembly and assembly operations.

[0049] The present invention provides a mining dump truck fender disassembly and assembly tool and a method of use. Aiming at the problem that the disassembly and assembly efficiency of the mining dump truck fender is low due to the position, weight and angle factors, and there are potential safety hazards in the disassembly and assembly process, a special disassembly and assembly tool and a method of use are designed.
