Abstract
Description
Technical Field
[0001] This utility model relates to the field of jacking equipment technology, and in particular to a jacking equipment for the maintenance of mining equipment. Background Technology
[0002] Mining equipment maintenance and jacking equipment is a type of specialized equipment used to lift and raise the equipment or its components during the maintenance, repair, and installation of various mining machinery and equipment to facilitate operation.
[0003] For some existing equipment that is directly attached to the ground or has a low distance from the ground, the lifting device itself has a certain height, so it cannot be placed under the equipment, which makes it impossible to raise the equipment and thus makes it impossible to perform maintenance on the lower side of the equipment.
[0004] Existing patent (publication number: CN220502575U) discloses an equipment maintenance lifting device, comprising a base plate, a sliding plate slidably fitted on the base plate, a support plate mounted on the sliding plate, multiple hydraulic cylinders fixed on the sliding plate, the output ends of the hydraulic cylinders fixedly connected to the support plate, a crossbar slidably fitted on the support plate, a threaded rod rotatably fitted inside the crossbar, and two clamping blocks slidably fitted inside the crossbar, the two clamping blocks corresponding to the two ends of the threaded rod respectively, and telescopic rods rotatably fitted at both ends of the crossbar. In this utility model, the crossbar is slidably installed on the support plate, the threaded rod is rotatably installed inside the crossbar, and the two clamping blocks are installed inside the crossbar. The equipment can be clamped by the clamping blocks, thus eliminating the need to place the device under the equipment. This allows for the lifting of equipment placed directly on the ground, facilitating maintenance. Furthermore, the support plate can be used to support the equipment after it is lifted, improving the stability of the support.
[0005] Existing patents offer solutions to the above problems, but they lack a structure that allows for flexible adaptation to different mining equipment. This results in lifting operations that can only be performed on mining equipment of specific specifications, shapes, and relatively simple bottom structures in practical applications, thus reducing the flexibility of using the lifting equipment.
[0006] Therefore, a mining equipment maintenance lifting device is proposed. Utility Model Content
[0007] The purpose of this utility model is to provide a mining equipment maintenance lifting device that can solve the problem that existing lifting devices lack a structure that can flexibly adapt to different mining equipment, resulting in the fact that in practical applications, they can only be used to lift mining equipment of specific specifications, shapes and relatively simple bottom structures, thereby reducing the flexibility of the lifting device in use.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] Please see Figure 1-5 The present invention provides the following technical solution:
[0028] A mining equipment maintenance lifting device includes a hydraulic jack body 1, a connecting mechanism 2 fixedly connected to the telescopic end of the top of the hydraulic jack body 1, and a support mechanism 3 slidably connected to the inner side of the connecting mechanism 2.
[0029] The connecting mechanism 2 includes a fixing ring 21, a connecting rod 22, a connecting plate 23, a hydraulic telescopic rod 24, a lower shovel plate 25, a limiting rod 26, and a plug groove 27. The fixing ring 21 is fixedly connected to the telescopic end at the top of the hydraulic jack body 1. The connecting rod 22 is fixedly connected to the surface of the fixing ring 21. The connecting plate 23 is fixedly connected to the bottom of the connecting rod 22. The hydraulic telescopic rod 24 is fixedly connected to the right side of the connecting plate 23. The lower shovel plate 25 is fixedly connected to the telescopic end of the hydraulic telescopic rod 24. The limiting rod 26 is fixedly connected to the top of the lower shovel plate 25. The plug groove 27 is opened at the bottom right side of the lower shovel plate 25.
[0030] In this embodiment: By setting the hydraulic jack body 1 to operate based on hydraulic principles, it can generate a large and relatively stable lifting force, which can meet the lifting needs of mining equipment of different weights and sizes during maintenance. The fixing ring 21 firmly fixes the connecting mechanism 2 to the telescopic end at the top of the hydraulic jack body 1, forming a stable connection point, ensuring that the lifting force generated by the hydraulic jack can be transmitted smoothly and without loss to the various components of the subsequent connecting mechanism 2. The connecting rod 22 connects the fixing ring 21 and the connecting plate 23. The connecting plate 23 bears the force transmitted from the connecting rod 22 on the one hand, and supports and limits the hydraulic telescopic rod 24 and the fixing plate 31 on the other hand. Furthermore, as the hydraulic jack body 1 moves up and down, it drives the hydraulic telescopic rod 24 and the fixed plate 31 to move up and down as well. The hydraulic telescopic rod 24 can extend and retract according to the actual situation, driving the lower shovel plate 25 to flexibly change position. The lower shovel plate 25 can be inserted into the bottom of the side of the equipment to be repaired as the hydraulic telescopic rod 24 extends and retracts, supporting and limiting both sides of the bottom of the equipment to be repaired. The limiting rod 26 provides a limiting and guiding function for the sliding of the pull plate 33, ensuring that the pull plate 33 can only move in a straight line in the up and down direction along the limiting rod 26. The insertion slot 27 provides a track for the sliding of the slider 35 in the support mechanism 3, making it convenient for the user to connect the support mechanism 3 to the connecting mechanism 2.
[0031] Specifically, such as Figure 3 As shown, the support mechanism 3 includes a fixed plate 31, several return springs 32, a pull plate 33, a support plate 34, a slider 35, several support rods 36 and a contact plate 37. The fixed plate 31 is fixedly connected to the right side of the connecting plate 23.
[0032] Specifically, such as Figure 3 As shown, the reset spring 32 is fixedly connected to the top of the fixed plate 31, the pull plate 33 is slidably connected to the surface of the limit rod 26, and the bottom of the pull plate 33 is fixedly connected to the top of the reset spring 32.
[0033] Specifically, such as Figure 3As shown, slider 35 is fixedly connected to both sides of support plate 34, slider 35 is slidably connected to the inner side of insertion slot 27, support rod 36 is fixedly connected to the top of support plate 34, and contact plate 37 is fixedly connected to the top of support rod 36.
[0034] In this embodiment: the fixed plate 31 supports and limits the return spring 32. When the user releases the pull plate 33, the return spring 32 applies a downward return force to the pull plate 33, so that the bottom of the pull plate 33 contacts the edge of the equipment to be repaired. The pull plate 33 and the lower shovel plate 25 form a clamping engagement, clamping the side of the mining equipment to be repaired. The support plate 34 supports and limits the support rod 36 and the slider 35. The slider 35 can drive the support plate 34 to slide into the insertion slot 27, so that the support plate 34 drives the support rod 36 and the contact plate 37 to contact the bottom of the equipment to be repaired. The support rod 36 supports and limits the contact plate 37. The larger contact area of the contact plate 37 can make the lifting force act more evenly on the equipment, reducing the possibility of excessive local pressure causing squeezing, scratching and other damage to the surface of the equipment.
[0035] Specifically, such as Figure 4 As shown, a reinforcing rod 4 is fixedly connected to the outside of the support rod 36, and the surface of the reinforcing rod 4 is coated with an anti-corrosion coating.
[0036] Specifically, such as Figure 5 As shown, a limiting ring 5 is fixedly connected to the top of the limiting rod 26, and a buffer pad 6 is sleeved on the bottom surface of the limiting ring 5.
[0037] In this embodiment: by setting the reinforcing rod 4, the overall stability of the support structure composed of the support rods 36 is enhanced, so that the entire support structure can more reliably distribute the lifting force. By setting the anti-corrosion coating, the external corrosive factors can be effectively blocked from eroding the reinforcing rod 4, slowing down its rusting and corrosion rate, thereby extending the service life of the entire lifting equipment. By setting the limiting ring 5, a clear limiting boundary is provided for the upward movement of the pull plate 33. By setting the buffer pad 6, when the pull plate 33 moves upward and contacts the limiting ring 5, the buffer pad 6 can effectively buffer the impact force between the two.
[0038] Specifically, such as Figure 3 As shown, a handle 7 is fixedly connected to the top of the pull plate 33, and the surface of the handle 7 is engraved with anti-slip texture.
[0039] Specifically, such as Figure 4 As shown, threaded holes 8 are provided on both sides of the bottom of the insertion slot 27 and both sides of the slider 35, and a fixing screw 9 is threadedly connected to the inner side of the threaded hole 8.
[0040] In this embodiment: by providing a handle 7, it is convenient for the user to move the pull plate 33 upward. By providing anti-slip texture, the friction between the hand and the handle 7 is increased, so that the operator can apply force steadily and comfortably. By providing a threaded hole 8, the fixing screw 9 can be supported and limited. By providing a fixing screw 9, the slider 35 can be firmly fixed to the inner side of the insertion groove 27.
[0041] Working Principle: When mining equipment needs to be lifted for maintenance, the operator first moves the hydraulic jack body 1 to the corresponding positions on both sides of the equipment to be lifted. Then, the user powers on and starts the hydraulic jack, which immediately begins to work. The telescopic end at the top drives the fixed ring 21 to move up and down. Through the transmission of the connecting rod 22 and the connecting plate 23, the position of the lower shovel plate 25 also changes accordingly. The operator adjusts the initial position of the lower shovel plate 25 to ensure that the top of the lower shovel plate 25 is at a suitable height below the bottom of the equipment to be lifted. Afterward, the operator powers on and starts the hydraulic telescopic rod 24, which drives the lower shovel plate 25 to move to the left or right side of the bottom of the equipment to be lifted. When the top of the lower shovel 25 successfully contacts the side of the equipment to be lifted, the user closes the hydraulic telescopic rod 24, causing the lower shovel plate 25 to remain in that position. At this time, the operator holds the handle 7 and pulls the pull plate 33 upward along the limit rod 26. The upward movement of the pull plate 33 compresses the return spring 32, causing it to undergo elastic deformation and store elastic potential energy. When the bottom of the pull plate 33 passes the side of the equipment to be lifted, the operator releases the handle 7. The pull plate 33 will then move downward under the pulling force of the return spring 32 until it returns to near its initial position, thus forming a stable clamping force on the side of the equipment to be lifted together with the lower shovel plate 25. At the same time, the operator follows the same operating procedure to apply the same hydraulic telescopic rod to the other side of the equipment to be lifted. The same operation is performed on the jack body 1. After the bottom of both sides of the equipment is in close contact with the top of the corresponding lower shovel plate 25, the hydraulic jack bodies 1 on both sides are energized and started again. At this time, the telescopic end of the hydraulic jack body 1 begins to extend upward, driving the lower shovel plate 25 to move upward synchronously. The lower shovel plate 25 receives the lifting force from the hydraulic jack body 1 and steadily transmits this force to the bottom of the equipment that needs to be lifted. Relying on the balanced lifting force transmitted by the lower shovel plates 25 on both sides, the equipment that needs to be lifted is pushed to move upward slowly. After the mining equipment is lifted to a suitable height, the operator inserts the support plate 34 of the support mechanism 3 into the inner side of the insertion slot 27 through the sliders 35 on both sides, and slowly slides the support plate 34 along the insertion slot 27. After all the operations are completed, the operator uses the fixing screw 9 to pass through the threaded holes 8 on both sides of the slider 35 and the insertion slot 27, and securely fixes the slider 35 and the insertion slot 27 together through the threaded connection, ensuring that the support mechanism 3 is stably installed in the corresponding position. At this time, the top of the contact plate 37 will be in close contact with the bottom of the mining equipment, and begin to provide reliable support for the lifted equipment. After all the maintenance work of the mining equipment is completed, the operator performs the equipment reset operation in the reverse order of the above operations. First, the fixing screw 9 is removed to separate the slider 35 from the insertion slot 27, and then the contact plate 37 is disengaged from the bottom of the mining equipment. The user then restarts the hydraulic telescopic rod 24. Through the extension and retraction of the hydraulic telescopic rod 24...Simply return the lower scraper plate 25 to its initial position.
[0042] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
