[0019] The preferred embodiments of this application are described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit this application.

[0020] like Figures 1 to 3 As shown in the embodiment of this application, a lifting tool for disassembling and assembling a steering pump and lifting pump of an open-pit mining truck is proposed, including: a bracket 1, a lifting device 2, a platform 3, and a binding mechanism 4; the lifting device 2 includes a lifting mechanism 21, which is mounted on the bracket 1 and moves along the height direction of the bracket 1; the platform 3 is connected to the lifting mechanism 21, which drives the platform 3 to move along the height direction of the bracket 1; the binding mechanism 4 is mounted on the platform 3 and binds objects to the platform 3.

[0021] The lifting tool for disassembling and assembling the steering pump and lifting pump of the open-pit mining truck provided in this application embodiment includes a bracket 1, a lifting device 2, a platform 3, and a binding mechanism 4. The bracket 1 provides stable support for the entire tool. The lifting platform 3 is used to place the pump body. By installing the platform 3 on the lifting mechanism 21 of the lifting device 2, the pump body is lifted by the lifting mechanism 21, and the height of the pump body is adjusted. This replaces the traditional manual high-altitude hoisting operation, simplifies the maintenance process, reduces the difficulty of maintenance, reduces the number of maintenance personnel, reduces the workload of maintenance personnel, improves maintenance efficiency, and eliminates the risks of high-altitude operations, thereby improving maintenance safety. The binding mechanism 4 fixes the pump body on the platform 3 to prevent the pump body from slipping off the platform 3 during the lifting and moving of the tool, thereby further improving the safety and reliability of the open-pit mining truck maintenance process.

[0022] like Figures 1 to 3 As shown, in one feasible embodiment, the lifting tool for disassembling and assembling the steering pump and lifting pump of the open-pit mine truck further includes: a lifting guide rail 5, on which a slider is slidably connected, the lifting guide rail 5 is arranged along the height direction of the bracket 1, the lifting guide rail 5 is connected to the bracket 1, and the lifting mechanism 21 is connected to the slider.

[0023] In this technical solution, the slider is slidably connected to the lifting guide rail 5, and the lifting mechanism 21 is installed on the slider. The lifting mechanism 21 moves synchronously with the slider, so as to guide and constrain the movement of the lifting mechanism 21 by using the lifting guide rail 5, thereby ensuring the stability of the platform 3 during the lifting process, reducing the shaking of the platform 3 during the lifting process, and keeping the pump body stable during the height adjustment process. This is beneficial to improving the accuracy and reliability of the pump body when installing the hole.

[0024] like Figures 1 to 3 As shown, in one feasible implementation, the first end of the platform 3 is rotatably connected to the lifting mechanism 21. The lifting tool for disassembling and assembling the steering pump and lifting pump of the open-pit mining truck also includes: an angle adjustment device 6. The angle adjustment device 6 is located below the platform 3. The first end of the angle adjustment device 6 is rotatably connected to the lifting mechanism 21, and the second end of the angle adjustment device 6 is rotatably connected to the second end of the platform 3, so as to adjust the angle of the platform 3 by extending and retracting the angle adjustment device 6.

[0025] In this technical solution, one end of the platform 3 is rotatably connected to the lifting mechanism 21, and the angle adjustment device 6 is set below the platform 3 to adjust the pitch angle of the platform 3. This allows the operator to fine-tune the tilt angle of the pump body, thereby better aligning it with the non-parallel mounting surfaces on the truck chassis. This enables the splines or bolt holes of the pump body to be quickly aligned with the mating structures on the truck, reducing the difficulty of drilling during pump body installation, reducing the maintenance difficulty of open-pit mining trucks, and improving maintenance efficiency.

[0026] Furthermore, two angle adjustment devices 6 are provided below the platform 3. The two angle adjustment devices 6 are arranged symmetrically on the platform 3. The two angle adjustment devices 6 simultaneously support and adjust the angle of the platform 3 so that the load on the platform 3 is evenly distributed on the two angle adjustment devices 6, thereby improving the load capacity of the platform 3. This is suitable for maintenance scenarios of heavy trucks in open-pit coal mines and improves maintenance safety.

[0027] Furthermore, two binding mechanisms 4 are provided on the platform 3. The two binding mechanisms 4 bind the pump body on the platform 3 at the same time to prevent the pump body from moving when the platform 3 is flipped, and to keep the pump body stable during the process of adjusting the pump body angle.

[0028] like Figure 4 As shown, in one feasible embodiment, the angle adjustment device 6 includes: a fixed base 61, a lower connecting plate 62, an upper connecting plate 63, and a telescopic mechanism 64; the fixed base 61 is connected to the lifting mechanism 21; the lower connecting plate 62 is connected to the fixed base 61; the upper connecting plate 63 is connected to the bottom surface of the platform 3; the first end of the telescopic mechanism 64 is rotatably connected to the lower connecting plate 62, and the second end of the telescopic mechanism 64 is rotatably connected to the upper connecting plate 63.

[0029] In this technical solution, one end of the telescopic mechanism 64 is mounted on the fixed base 61 via the lower fixed plate 32, and then fixed to the lifting mechanism 21 via the fixed base 61; the other end of the telescopic mechanism 64 is mounted on the bottom surface of the platform 3 via the upper fixed plate 32, so that the platform 3 can be flipped by telescopic mechanism 64, and the telescopic mechanism 64 pushes or pulls the other end of the platform 3 to achieve smooth adjustment of the angle of the platform 3, ensuring the rigidity and accuracy of the angle adjustment.

[0030] like Figure 4 As shown, in one feasible embodiment, the telescopic mechanism 64 includes: a lower adjusting rod 641, an upper adjusting rod 642, an adjusting sleeve 643, a first fastening nut 644, and a second fastening nut 645; the first end of the lower adjusting rod 641 is rotatably connected to the lower connecting plate 62; the first end of the upper adjusting rod 642 is rotatably connected to the upper connecting plate 63; the first end of the adjusting sleeve 643 is threadedly connected to the second end of the lower adjusting rod 641, and the second end of the adjusting sleeve 643 is threadedly connected to the second end of the upper adjusting rod 642; the first fastening nut 644 is fitted on the outside of the lower adjusting rod 641, and is threadedly connected to the lower adjusting rod 641, and is in contact with the first end of the adjusting sleeve 643; the second fastening nut 645 is fitted on the outside of the upper adjusting rod 642, and is threadedly connected to the upper adjusting rod 642, and is in contact with the second end of the adjusting sleeve 643.

[0031] In this technical solution, the telescopic mechanism 64 adopts a bidirectional threaded sleeve 42 structure. By screwing the adjusting sleeve 643, the thread of the adjusting sleeve 643 engages with the threads of the upper adjusting rod 642 and the lower adjusting rod 641, thereby precisely and subtly changing the overall length of the telescopic mechanism 64 and achieving fine adjustment of the platform 3 angle. After the adjusting sleeve 643 is screwed into place, the first fastening nut 644 and the second fastening nut 645 are screwed on, so that the first fastening nut 644 and the second fastening nut 645 respectively fit against the two end faces of the adjusting sleeve 643, thereby locking the adjusting sleeve 643 from both ends, preventing the threads from loosening due to vibration, and ensuring the long-term stability of the platform 3 angle under load, ensuring safety and reliability.

[0032] like Figure 1 and Figure 2 As shown, in one feasible embodiment, the lifting device 2 further includes: a hydraulic cylinder 22, a directional sprocket 23, and a chain 24; the hydraulic cylinder 22 is arranged along the height direction of the support 1, and the fixed end of the hydraulic cylinder 22 is connected to the support 1; the directional sprocket 23 is fixedly connected to the telescopic end of the hydraulic cylinder 22; the first end of the chain 24 is connected to the support 1, the chain 24 is wrapped around the outside of the directional sprocket 23, and the second end of the chain 24 is connected to the lifting mechanism 21 to drive the lifting mechanism 21 to perform lifting movements.

[0033] In this technical solution, the lifting device 2 adopts a combined transmission method of chain 24 and sprocket. The hydraulic cylinder 22 is fixed on the bracket 1, and the directional sprocket 23 is installed on the telescopic end of the hydraulic cylinder 22. The hydraulic cylinder 22 provides linear driving force to the directional sprocket 23. Through the transmission cooperation between the chain 24 and the directional sprocket 23, the chain 24 drives the lifting mechanism 21 to move up and down, thereby lifting the pump body to the working height required by the truck chassis through the lifting of the platform 3.

[0034] Furthermore, a hydraulic controller 9 is provided on the bracket 1. The hydraulic controller 9 is connected to the hydraulic cylinder 22 so as to control the extension and retraction of the hydraulic cylinder 22, thereby controlling the height of the directional sprocket 23, so that the directional sprocket 23 and the chain 24 can be driven together.

[0035] like Figure 5 As shown, in one feasible embodiment, the binding mechanism 4 includes: a wire rope 41, a sleeve 42, and a locking screw 43; the wire rope 41 is disposed above the platform 3, and both ends of the wire rope 41 pass through the platform 3; the inner wall of the sleeve 42 is provided with internal threads, the sleeve 42 is connected to the bottom surface of the platform 3, and the wire rope 41 passes through the sleeve 42; the locking screw 43 is arranged perpendicular to the sleeve 42, the locking screw 43 is threadedly connected to the sleeve 42, and the locking screw 43 presses the wire rope 41 into the sleeve 42.

[0036] In this technical solution, the end of the wire rope 41 passes through the platform 3 and the sleeve 42 in sequence, and the end of the locking screw 43 presses the wire rope 41 tightly against the inner wall of the sleeve 42 to prevent the wire rope 41 from loosening, ensuring the stability of the wire rope 41 binding the pump body on the platform 3, so that the platform 3 can carry the pump body safely and reliably.

[0037] like Figure 5 As shown, in one feasible embodiment, the binding mechanism 4 further includes: an adjusting screw 44, an adjusting nut 45, and a locking nut 46; the adjusting screw 44 is fixedly connected to the end of the wire rope 41, and the adjusting screw 44 is slidably connected inside the sleeve 42, with each adjusting screw 44 corresponding to one end of the wire rope 41; the adjusting nut 45 is fitted on the outside of the adjusting screw 44, and the adjusting nut 45 is threadedly connected to the adjusting screw 44; the locking nut 46 is fitted on the outside of the adjusting screw 44, and the locking nut 46 is threadedly connected to the adjusting screw 44, and the locking nut 46 is located below the adjusting nut 45.

[0038] In this technical solution, the adjusting screw 44 is fixedly connected to the wire rope 41, and the adjusting screw 44 extends from the end of the sleeve 42 away from the platform 3. The adjusting nut 45 is threaded on the outside of the adjusting screw 44, so that the length of the wire rope 41 extending out of the sleeve 42 can be finely adjusted by turning the adjusting nut 45, thus limiting the upward displacement of the wire rope 41 relative to the platform 3, and further finely adjusting the tightness of the wire rope 41 binding to adapt to the irregular shape of the pump body, ensuring that the pump body is firmly tightened and fixed in the preset position of the platform 3. By setting a locking nut 46 below the adjusting nut 45, the locking nut 46 contacts the adjusting nut to limit the adjustment nut, preventing the adjusting nut from rotating loosely, and improving the flexibility and accuracy of the binding mechanism 4 adjustment.

[0039] like Figure 5 As shown, in one feasible embodiment, the platform 3 includes: a support plate 31 and a fixing plate 32; the fixing plate 32 is arranged perpendicular to the support plate 31, the fixing plate 32 is connected to the support plate 31, and the fixing plate 32 is rotatably connected to the lifting mechanism 21.

[0040] In this technical solution, the support plate 31 serves as the supporting structure for the pump body, and the fixed plate 32 serves as the rotating connection point between the support plate 31 and the lifting mechanism 21, while also enhancing the structural rigidity of the platform 3 itself. By making the fixed plate 32 perpendicular to the support plate 31, it is convenient to rotatably connect the support plate 31 to the lifting mechanism 21 through the fixed plate 32, and make the axis of rotation of the support plate 31 perpendicular to the direction of movement of the lifting mechanism 21, thereby realizing the adjustment of the pitch angle of the platform 3, so that the platform 3 can flexibly and stably complete the pitch movement when carrying the pump body.

[0041] like Figure 1 and Figure 2 As shown, in one feasible embodiment, the lifting tool for disassembling and assembling the steering pump and lifting pump of the open-pit mine truck further includes: a moving wheel 7 and a handrail 8; the moving wheel 7 is located at the bottom of the support 1; the handrail 8 is located on the side of the support 1 away from the platform 3.

[0042] In this technical solution, by installing casters 7 at the bottom of the chassis, the tool can transport the pump body, improving work efficiency. During use, after the pump body is secured to the platform 3, the tool, along with its main body, can be moved under the truck chassis, eliminating the need to secure the pump body in confined maintenance spaces and reducing operational difficulty. The handle 8 provides the operator with a point of leverage for moving the tool; the combination of the handle 8 and the casters 7 enhances the tool's portability and ease of operation.

[0043] As a preferred option, the 7th swivel brake wheel of the moving wheel locks the tool after it is moved into position, ensuring that the horizontal distance between the tool and the truck floor does not change.

[0044] When using the pump, first move the tool under the truck chassis and then lock the moving wheels 7; use the tying mechanism 4 to fix the pump body to the pallet 31. Step on the hydraulic controller 9 to adjust the extension length of the hydraulic cylinder 22, raising the platform 3 to a working height of 2.1m; then rotate the adjusting sleeve 643 to fine-tune until the splines are fully engaged; after removing the bolts, slowly lower the pump body to complete disassembly.

[0045] It will be readily understood by those skilled in the art that the aforementioned advantageous methods can be freely combined and superimposed without conflict.

[0046] The above are merely preferred embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application. The above are merely preferred embodiments of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of this application, and these improvements and modifications should also be considered within the protection scope of this application.
