Description

Technical Field

[0001] The utility model relates to a maintenance device for a crawler chassis vehicle, in particular to a device for facilitating the disassembly and assembly of a driving wheel of a crawler chassis. Background Technique

[0002] The driving wheel of a crawler chassis is an important component on a crawler vehicle or mechanical equipment, used to drive and control the movement of the crawler. The driving wheel is usually located at the front or rear of the crawler chassis, contacts with the crawler, and drives the rotation of the crawler through a power transmission system, thereby pushing the entire crawler chassis to move. The driving wheel generally consists of a steel rim and a crawler contact surface made of rubber or metal, and is connected to an engine or an electric motor through an internal transmission system (such as gears, chains, etc.). When power is input to the driving wheel, it will push the movement of the crawler through friction and transmission, thereby driving the entire crawler chassis to move forward or turn.

[0003] The existing technology has the following problems: The existing method for disassembling and assembling the driving wheel mainly relies on manpower. Due to the high weight of the driving wheel, the disassembly and assembly of the driving wheel are rather cumbersome, resulting in low work efficiency of disassembly and assembly; and during the disassembly and assembly process, the staff is prone to exhaustion, causing the driving wheel to shift, and thus the probability of injury to the staff is relatively high. Content of the Utility Model

[0004] To solve the above technical problems, a device for facilitating the disassembly and assembly of a driving wheel of a crawler chassis is provided, which solves the problems of low work efficiency of current disassembly and assembly and relatively high probability of injury to the staff.

[0005] To achieve the above object, the technical solution adopted by the utility model is as follows:

[0006] A device for facilitating the disassembly and assembly of a driving wheel of a crawler chassis, including a bottom plate, a plurality of moving wheels are fixedly installed on the bottom surface of the bottom plate, and the plurality of moving wheels are symmetrically distributed about the center line of the bottom plate. A plurality of guiding components are fixedly installed on the upper surface of the bottom plate, and the plurality of guiding components are symmetrically distributed about the center line of the bottom plate. A connecting groove is opened on the upper surface of the bottom plate, and a hydraulic rod is arranged inside the connecting groove. The bottom plate and the hydraulic rod are fixedly connected by a first bolt. The upper end of the hydraulic rod is fixedly installed with a push plate. A moving plate is arranged above the hydraulic rod. A slot is opened on the bottom surface of the moving plate corresponding to the push plate. Two supporting plates are fixedly installed on the upper surface of the moving plate, and the two supporting plates are symmetrically distributed about the center line of the bottom plate. A fixing mechanism is arranged above the supporting plates, and the fixing mechanism is fixedly connected to both supporting plates.

[0007] Preferably, the guiding component includes a connecting plate, the connecting plate is fixedly connected to the bottom plate, a fixing plate is arranged on the upper surface of the connecting plate, the fixing plate is fixedly connected to the connecting plate by a second bolt, fixing grooves are formed inside both the fixing plate and the connecting plate, and a guide rod is arranged inside the fixing groove.

[0008] Preferably, a sliding groove is formed through the inside of the moving plate corresponding to the guide rod, and an annular plate corresponding to the guide rod is fixedly installed inside the sliding groove.

[0009] Preferably, an interference fit is adopted between the fixing groove and the guide rod, and the fit tolerance is 1 mm - 2 mm.

[0010] Preferably, the fixing mechanism includes two side plates, the two side plates are respectively fixedly connected to the two support plates, rotating shafts are rotatably installed on one side of the two side plates close to each other, rotating plates are fixedly installed at one ends of the two rotating shafts close to each other, an annular circular plate is arranged above the two support plates, and the annular circular plate is fixedly connected to both the two rotating plates.

[0013] Compared with the prior art, the advantages of the present utility model are as follows: By arranging a hydraulic rod and a fixing mechanism, an annular circular plate is arranged inside the fixing mechanism. The hydraulic rod pushes the fixing structure on the moving plate to make the annular circular plate correspond to the driving wheel. Workers can quickly disassemble and assemble the driving wheel through the annular circular plate, thereby improving work efficiency; at the same time, since the disassembly of the driving wheel entirely relies on the equipment, and the automatic driving of the hydraulic rod and the stable fixation of the fixing mechanism reduce the dependence on manual operation.

Specific embodiments

[0021] The following description is used to disclose the present utility model so that those skilled in the art can implement the present utility model. The preferred embodiments described below are only examples, and those skilled in the art can think of other obvious variations.

[0022] Referring to Figures 1-6 As shown, a device for facilitating the disassembly and assembly of the driving wheel of a crawler chassis includes a bottom plate 1. A plurality of moving wheels 2 are fixedly installed on the bottom surface of the bottom plate 1, and the plurality of moving wheels 2 are symmetrically distributed about the center line of the bottom plate 1. Workers can move the device through the moving wheels 2. A plurality of guiding components 3 are fixedly installed on the upper surface of the bottom plate 1, and the plurality of guiding components 3 are symmetrically distributed about the center line of the bottom plate 1. A connecting groove 4 is formed on the upper surface of the bottom plate 1, and a hydraulic rod 5 is arranged inside the connecting groove 4. The bottom plate 1 and the hydraulic rod 5 are fixedly connected by a first bolt 6. A pushing plate 7 is fixedly installed at the upper end of the hydraulic rod 5. A moving plate 8 is arranged above the hydraulic rod 5. A slot 9 is formed on the bottom surface of the moving plate 8 corresponding to the pushing plate 7. The hydraulic rod 5 pushes the pushing plate 7 into the slot 9 to move the moving plate 8 upward. Two supporting plates 10 are fixedly installed on the upper surface of the moving plate 8, and the two supporting plates 10 are symmetrically distributed about the center line of the bottom plate 1. A fixing mechanism 11 is arranged above the supporting plates 10. The fixing mechanism 11 is fixedly connected to both of the supporting plates 10. When the fixing mechanism 11 moves to correspond to the driving wheel of the crawler chassis, the worker fixes the driving wheel of the crawler chassis on the fixing mechanism 11, thereby facilitating the disassembly and installation of the driving wheel of the crawler chassis.

[0023] As Figure 4 shown, the guiding component 3 includes a connecting plate 12. The connecting plate 12 is fixedly connected to the bottom plate 1. A fixing plate 13 is arranged on the upper surface of the connecting plate 12. The fixing plate 13 and the connecting plate 12 are fixedly connected by a second bolt 14. Fixing grooves 15 are formed inside both the fixing plate 13 and the connecting plate 12, and a guide rod 16 is arranged inside the fixing grooves 15. The fixing plate 13 and the connecting plate 12 support the guide rod 16.

[0024] AsFigure 5 As shown, a chute 17 is formed through the inside of the moving plate 8 corresponding to the guide rod 16. An annular plate 18 corresponding to the guide rod 16 is fixedly installed inside the chute 17. The guide rod 16 and the annular plate 18 cooperate with each other to make the process of the hydraulic rod 5 pushing the moving plate 8 move more smoothly and prevent the moving plate 8 from shifting.

[0025] As Figure 4 shown, an interference fit is adopted between the fixing groove 15 and the guide rod 16, and the fit tolerance is 1 mm - 2 mm. The interference fit causes a certain pressure between the fixing groove 15 and the guide rod 16. This pressure makes the connection between the two closer and not easy to loosen; the interference amount of 1 mm - 2 mm ensures sufficient connection strength, so that during the disassembly and assembly process of the driving wheel of the crawler chassis, the guide rod 16 can move stably in the fixing groove 15, not easy to shift or shake, and at the same time this interference amount makes the disassembly and assembly process still relatively easy.

[0026] As Figure 6 shown, the fixing mechanism 11 includes two side plates 19. The two side plates 19 are respectively fixedly connected to the two support plates 10. Rotating shafts 20 are rotatably installed on the sides of the two side plates 19 close to each other. Rotating plates 21 are fixedly installed at the ends of the two rotating shafts 20 close to each other. An annular circular plate 22 is provided above the two support plates 10. The annular circular plate 22 is fixedly connected to the two rotating plates 21. A connection hole corresponding to the threaded hole on the driving wheel of the crawler chassis is formed through the inside of the annular circular plate 22. The rotating shaft 20 drives the annular circular plate 22 to rotate to correspond to the driving wheel. The staff inserts a bolt into the connection hole and threads it into the threaded hole of the driving wheel to fix the driving wheel to the annular circular plate 22.

[0027] As Figure 6 shown, a motor 23 is provided on the side of the support plate 10 corresponding to the rotating shaft 20. The rotating shaft 20 penetrates through the support plate 10 and is fixedly connected to the motor 23. The motor 23 serves as the power source for the rotating shaft 20.

[0028] As Figures 1-6 shown, a reinforcing rib 24 is provided on the side of the support plate 10 away from the rotating plate 21. Since the weight of the driving wheel is relatively high, the reinforcing rib 24 is used to increase the strength and stability of the support plate 10 and prevent deformation or damage during the installation and disassembly process.

[0029] Working principle: When disassembling the driving wheel of the crawler chassis, the staff pushes the equipment, so that the whole equipment moves to a suitable position through the moving wheels 2. The motor 23 drives the annular circular plate 22 on the rotating shaft 20 to rotate. At the same time, the hydraulic rod 5 pushes the push plate 7 into the slot 9, so that the moving plate 8 moves along the axial direction of the guide rod 16 to make the annular circular plate 22 correspond to the driving wheel. The staff uses bolts to fix the driving wheel on the annular circular plate 22, thereby realizing disassembly.

[0030] The foregoing has shown and described the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments, and what is described in the above embodiments and the specification is only the principle of the present utility model. Without departing from the spirit and scope of the present utility model, various changes and improvements will occur to the present utility model, and all these changes and improvements fall within the scope of the present utility model claimed.
