Description

Technical Field

[0001] This utility model relates to the technical field of truck transfer case disassembly and assembly tools, and in particular to a special tool for disassembling and assembling an articulated truck transfer case. Background Technology

[0002] Mining trucks are mostly articulated trucks, also known as articulated trucks. They are heavy-duty dump trucks used in open-pit mines to complete rock and soil stripping and ore transportation tasks. Their working characteristics are short transport range and heavy load capacity. They are usually loaded with large electric shovels or hydraulic shovels and travel back and forth between the mining point and the unloading point. In the mining and quarrying industry, mining trucks are the key to efficient and high-productivity operation.

[0003] The transfer case of an articulated truck is located under the cab and connects to the gearbox. According to the equipment assembly manual, there are twenty-seven steps involved in its disassembly and assembly. The entire cab must be disassembled, and the transfer case must be lifted out along with the gearbox before the transfer case can be disassembled. This requires the assistance of lifting equipment, forklifts, and at least six people to disassemble the transfer case. Disassembling and assembling a single transfer case, not including the maintenance time, takes nearly a month, impacting equipment uptime and availability. Therefore, this invention provides a special tool for disassembling and assembling articulated truck transfer cases. By measuring the space under the articulated mining truck and analyzing the feasibility of disassembling and assembling the transfer case from the bottom, a special tool for disassembling and assembling the transfer case was developed. This reduces maintenance steps, maintenance time, and labor costs, improving maintenance efficiency and solving the aforementioned problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a special tool for disassembling and assembling articulated truck transfer cases, solving the problems of difficult disassembly and cumbersome maintenance procedures in existing articulated trucks.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A special tool for disassembling and assembling an articulated truck transfer case includes a horizontal jack. The top load-bearing tray of the horizontal jack is fixedly connected to a support base. The top two ends of the support base are respectively provided with a first ear seat and a second ear seat. The surfaces of the first ear seat and the second ear seat are each provided with four through holes.

[0007] Preferably, the support base is Y-shaped.

[0008] Preferably, the two upper ends of the support base are provided with semi-grooves.

[0009] Preferably, a horizontal axis is fixedly connected to the side of the first ear seat and the second ear seat that are far apart from each other.

[0010] Preferably, the two horizontal shafts are fixedly connected to the two semi-grooves respectively, and the horizontal shafts are welded to the inside of the semi-grooves.

[0011] Preferably, the top of both the first ear seat and the second ear seat is provided with a support groove.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] The drive shafts and splines at both ends of the articulated truck transfer case are removed. The first and second lugs are then fixed to the transfer case flange using four sets of bolts and nuts through through holes, allowing the support groove to engage with the drive shaft. The two horizontal shafts connected to the first and second lugs are fixed to the semi-grooves in the support base. The lower support rod is connected to a horizontal jack. Utilizing the adjustable height and reach of the horizontal jack, the articulated truck transfer case is moved from the bottom of the equipment, enabling the assembly to be disassembled and reassembled. With the assistance of this application, the transfer case can be directly disassembled, saving time on disassembling the cab and gearbox, reducing maintenance steps, lowering maintenance time and labor, improving maintenance efficiency, and solving the problems of existing articulated trucks being difficult to disassemble and having cumbersome maintenance procedures.

[0020] This application provides a special tool for disassembling and assembling the transfer case of an articulated truck, which effectively solves the problems of existing articulated trucks being difficult to disassemble and having complicated maintenance procedures. Example

[0021] like Figure 1-4 As shown, the technical solution in this application embodiment effectively solves the technical problems of existing articulated trucks being difficult to disassemble and requiring cumbersome maintenance procedures. The overall idea is as follows:

[0022] To address the problems existing in the prior art, this utility model provides a special tool for disassembling and assembling an articulated truck transfer case, including a horizontal jack 4. The top load-bearing tray of the horizontal jack 4 is fixedly connected to a support base 3. The top two ends of the support base 3 are respectively provided with a first ear seat 1 and a second ear seat 2. The surfaces of the first ear seat 1 and the second ear seat 2 are each provided with four through holes 8.

[0023] Support 3 is Y-shaped.

[0024] The two upper ends of the support base 3 are each provided with a semi-groove 5.

[0025] A horizontal shaft 6 is fixedly connected to the side of the first ear seat 1 and the second ear seat 2 that are far apart from each other.

[0026] Two horizontal shafts 6 are fixedly connected to two semi-grooves 5 respectively, and the horizontal shafts 6 are welded to the inside of the semi-grooves 5.

[0027] The top of both the first ear seat 1 and the second ear seat 2 is provided with a support groove 7.

[0028] The first ear seat 1 is fixed to the transfer case flange through the through hole 8 with bolts and nuts, and its top support groove 7 engages with the drive shaft.

[0029] The second ear seat 2 is fixed to the transfer case flange through the through hole 8 with bolts and nuts, and its top support groove 7 engages with the drive shaft.

[0030] The support seat 3 is used to connect the first ear seat 1, the second ear seat 2 and the horizontal jack 4, and plays the role of supporting and transmitting force.

[0031] The horizontal jack 4 utilizes its adjustable height and reach to remove the articulated truck transfer case from the bottom of the equipment, enabling the assembly and disassembly of the unit.

[0032] The half-groove 5 is used to accommodate and fix the horizontal shaft 6.

[0033] The horizontal axis 6 is used to connect and fix the first ear seat 1 and the second ear seat 2 to the support seat 3 respectively.

[0034] The support groove 7 is used to engage with the drive shaft, serving to position and support the drive shaft.
