[0020] The present invention will be further described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0021] like Figure 1 As shown, a sliding device includes: a slide rail 1, on which a hydraulic pump station mechanism 2, a sliding shoe mechanism 3 for supporting equipment, and a sliding drive mechanism 4 for pushing the sliding shoe mechanism 3 are arranged, and the sliding drive mechanism 4 is located between the hydraulic pump station mechanism 2 and the sliding shoe mechanism 3.

[0022] The structure of the slide rail 1 includes: a slide rail base 11, guide rails 12 are respectively arranged on both sides of the slide rail base 11, and the slide rail base 11 between the guide rails 12 on both sides forms a slideway 10. A plurality of check holes 121 are evenly distributed on the top of each guide rail 12, and a slide plate 101 is laid on the slideway 10. The bottom of the slide shoe mechanism 3 is supported on the slide plate 101.

[0023] In this embodiment, the slide plate 101 laid on the slideway 10 is made of MGE engineering plastic alloy, which has the advantages of large bearing capacity, good wear resistance, and good self-lubricating performance. Specifically, a plurality of slideway dividers 102 are arranged at fixed intervals in the longitudinal direction of the slideway 10, and two slide plates 101 are laid side by side on the slideway 10 between each two adjacent slideway dividers 102 and between the slideway dividers 102 and the end of the slideway 10, and each slide plate 101 is fixed to the slideway base 11 by bolts.

[0024] Since the mass of the equipment to be moved is hundreds of tons, the friction force is extremely large. In this embodiment, a slide plate 101 made of MGE engineering plastic alloy is laid in the slideway 10, which can greatly improve the wear resistance and bearing capacity of the slideway 10, thereby greatly extending the service life of the slideway 10. The slideway is separated by a slideway dividing strip 102, and each individual slide plate 101 is fixed by a pin column. Such a laying structure is very simple, which can greatly shorten the laying period, and can be easily adjusted in position. When one of the slide plates 101 is severely worn, it only needs to be replaced separately, which effectively saves the cost of equipment use.

[0025] like Figure 2 As shown, the structure of the sliding shoe mechanism 3 includes: a sliding shoe base 31, a steel plate 311 is provided at the bottom of the sliding shoe base 31, and both ends of the steel plate 311 are bent and tilted upward. The purpose of providing the steel plate 311 is to reduce the friction during sliding. The upward bending and tilting of both ends of the steel plate 311 can make it easier for the sliding shoe base 31 to slide on the slide plate 101, thereby greatly improving the smoothness of the sliding of the sliding shoe mechanism 3 in the slideway 10.

[0026] An equipment support seat 32 is arranged on the shoe base 31, and two hydraulic jacks 33 with self-locking mechanisms are fixedly arranged in the equipment support seat 32. A transport cap 34 for supporting the equipment is arranged on the top of the equipment support seat 32. The structure of the transport cap 34 includes: a cap top 341, and reinforcing plates 342 are arranged on both sides of the cap top 341. The arrangement of the reinforcing plates 342 can effectively improve the rigidity and stability of the transport cap 34. The cap top 341 is supported on the tops of two hydraulic jack plungers 331. The up and down movement of the two hydraulic jack plungers 331 can drive the transport cap 34 to move upward or downward, thereby driving the equipment supported on the transport cap 34 to move up and down. The sliding shoe bases 31 at both ends of the equipment support base 32 are respectively fixed with translation drive mechanism mounting bases 35, and the translation drive mechanism mounting bases 35 at each end are provided with translation drive mechanisms. The translation drive mechanisms at each end are connected to the equipment support base 32. The synchronous action of the translation drive mechanisms at both ends can drive the equipment support base 32 to translate back and forth in the lateral direction of the sliding shoe base 31, thereby driving the equipment supported on the transport top cap 34 to translate back and forth along the lateral direction of the sliding shoe base 31.

[0027] Specifically, the translation drive mechanism at both ends of the equipment support seat 32 is a double-axis hydraulic cylinder 36, the cylinder body of the double-axis hydraulic cylinder 36 at each end is fixed to the equipment support seat 32, and the two piston rods of each double-axis hydraulic cylinder 36 are respectively connected to the translation drive mechanism mounting seat 35 at the corresponding end.

[0028] like Figure 3 As shown, the structure of the self-locking mechanism of each hydraulic jack 33 includes: a hydraulic jack cylinder 332, the upper end of the hydraulic jack cylinder 332 protrudes from the top of the equipment support seat 32, the hydraulic jack cylinder 332 protruding from the equipment support seat 32 is externally threaded with a locking flange 36, the top of the hydraulic jack plunger 331 protrudes from the hydraulic jack cylinder 332, the outer wall of the hydraulic jack plunger 331 protruding from the hydraulic jack cylinder 332 is provided with a thread, and the hydraulic jack plunger 331 protruding from the hydraulic jack cylinder 332 is threaded with a self-locking ring 37, the bottom of the self-locking ring 37 is blocked on the self-locking sleeve 38, and the self-locking sleeve 38 is sleeved on the outside of the hydraulic jack plunger 331 and supported on the top of the hydraulic jack cylinder 332.

[0029] like Figure 4As shown, the sliding drive mechanism 4 includes a hydraulic cylinder 41. The hydraulic cylinder 41 is fixedly arranged in the cylinder seat 42, and the hydraulic pump station mechanism 2 is connected to the cylinder seat 42 so as to be linked with the cylinder seat 42. There are two hydraulic cylinders 41. The piston rod of the hydraulic cylinder 41 is connected to the slipper mechanism 3. The purpose of setting two hydraulic cylinders 41 is to greatly improve the sliding driving force of the slipper mechanism 3 and improve the driving stability. Check wheel mounting seats 5 are fixedly arranged on both sides of the cylinder seat 42, and the check wheel mounting seats 5 on both sides are respectively located at the top of the guide rail 12 on the corresponding side, and the front check wheel 6 and the rear check wheel 7 are hingedly arranged in the check wheel mounting seat 5 on each side. A non-return slot 51 is provided at the bottom of the non-return wheel mounting seat 5, and the front and rear ends of the non-return slot 51 respectively form a front stopper 511 and a rear stopper 512 of the slot. The front non-return wheel 6 and the rear non-return wheel 7 are respectively located at the front and rear ends of the non-return slot 51, and each non-return wheel has a working state and a rest state.

[0030] In this embodiment, the structure of the cylinder seat 42 and the installation structure of the hydraulic cylinder 41 in the cylinder seat 42 include: the cylinder seat 42 includes: a cylinder seat bottom plate 421, two side plates 422 and a cylinder seat partition plate 423 are fixedly arranged on the cylinder seat bottom plate 421, the cylinder seat partition plate 423 is located between the two side plates 422, and the two side plates 422 and one end of the cylinder seat partition plate 423 are fixedly arranged with a cylinder seat end plate 424, and a cylinder seat partition plate 423 and the two side plates 422 are formed between the cylinder seat partition plate 423 and the two side plates 422 for installation. The mounting cavity 43 of the hydraulic cylinder 41, the side plates 422 on both sides of each mounting cavity 43 and the inner wall of the cylinder seat partition 423 are provided with mounting slots 431, the cylinder fixing seat plate 44 is mounted in the mounting cavity 43 through the mounting slots 431, the cylinder fixing seat plate 44 is provided with a threaded through hole, the cylinder body of the hydraulic cylinder 41 is threadedly fixedly connected with the threaded through hole of the cylinder fixing seat plate 44, and one end of the cylinder body of the hydraulic cylinder 41 located in the mounting cavity 43 abuts against the cylinder seat end plate 424 in the mounting cavity 43. The above-mentioned cylinder seat 42 structure and the mounting structure of the hydraulic cylinder 41 in the cylinder seat 42 effectively ensure the stability of the installation of the hydraulic cylinder 41, thereby ensuring the stability of the sliding driving force.

[0031] The front check wheel 6 includes a front check wheel body 61 and a front check tooth 62. The front check tooth 62 is fixed to one side of the front check wheel body 61. A front first check stop surface 621 and a front second check stop surface 622 are provided on the front check tooth 62. A front check tooth inclined surface 623 is provided between the front first check stop surface 621 and the front second check stop surface 622. A front top support plane 611 and a front bottom support plane 612 are provided at the top and bottom of the front check wheel body 61, respectively. The front check tooth 62 is located on one side of the front top support plane 611 and the front bottom support plane 612 of the front check wheel body 61. The outer wall on the other side of the front top support plane 611 and the front bottom support plane 612 of the front check wheel body 61 is in an arc shape. The front first non-return blocking surface 621 and the front second non-return blocking surface 622 are both protruding from the front top support plane 611, and the center of gravity of the front non-return wheel 6 is biased toward one side of the front non-return tooth 62. The front top support plane 611 and the front bottom support plane 612 ensure that the front non-return wheel 6 is stably maintained in the working state or the resting state, and will not switch between the two states at will.

[0032] The front non-return wheel 6 in the rest state has its front non-return tooth 62 pointing vertically upward, and the front non-return tooth 62 is located at one end of the non-return wheel mounting seat 5 and is blocked by the non-return wheel mounting seat 5 at this end. The front non-return wheel 6 in the rest state can be rotated toward the non-return slot 51 by external force until the front non-return tooth 62 rotated thereon extends through the non-return slot 51, thereby realizing the transition from the rest state to the working state.

[0033] The front check tooth 62 on the front check wheel 6 in the working state extends into the check opening 121 at the top of the guide rail 12 below it through the check slot 51, the front first check blocking surface 621 of the front check tooth 62 located in the check opening 121 is blocked by the front blocking portion 511 of the slot, and the front second check blocking surface 622 is blocked by the inner wall of the check opening 121 located at the rear side relative to the movement direction of the sliding shoe mechanism 3, the lower end of the front first check blocking surface 621 of the front check tooth 62 in the check opening 121 is located above the check opening 121, and the front check tooth inclined surface 623 of the front check tooth 62 in the check opening 121 extends obliquely upward from the lower end of the front second check blocking surface 622 toward the direction of the front first check blocking surface 621 and extends out of the check opening; When the front check wheel 6 is in working state, the piston rod of the hydraulic cylinder 41 extends outward to push the slipper mechanism 3 supporting the equipment to move forward. Since the mass of the equipment is very large, the piston rod of the hydraulic cylinder 41 retracts inward, which can drive the cylinder seat 42 to drive the hydraulic pump station mechanism 2 to move toward the slipper mechanism 3. During this process, the front check tooth 62 can be rotated out of one check port 121 and then fall into another check port.

[0034] The rear check wheel 7 includes a rear check wheel body 71 and a rear check tooth 72. The rear check tooth 72 is fixed on one side of the rear check wheel body 71. A rear first check stop surface 721 and a rear second check stop surface 722 are provided on the rear check tooth 72. A rear check tooth inclined surface 723 is provided between the rear first check stop surface 721 and the rear second check stop surface 722.

[0035] The top and bottom of the rear check wheel body 71 are respectively provided with a rear top support plane 711 and a rear bottom support plane 712, and the rear check tooth 72 is located on one side of the rear top support plane 711 and the rear bottom support plane 712 of the rear check wheel body 71, and the outer wall on the other side of the rear top support plane 711 and the rear bottom support plane 712 of the rear check wheel body 71 is in an arc shape. The rear first check stop surface 721 and the rear second check stop surface 722 are both protruding from the rear top support plane 711, and the center of gravity of the rear check wheel 7 is biased toward one side of the rear check tooth 72. The rear top support plane 711 and the rear bottom support plane 712 ensure that the front check wheel 7 is stably maintained in the working state or the resting state, and will not switch between the two states at will.

[0036] The rear non-return wheel 7 in the rest state has its rear non-return tooth 72 pointing vertically upward, and the rear non-return tooth 72 is located at one end of the non-return wheel mounting seat 5 and is blocked by the non-return wheel mounting seat 5 at this end. The rear non-return wheel 7 in the rest state can be rotated toward the non-return slot 51 by external force until the rear non-return tooth 72 rotated thereon extends through the non-return slot 51, thereby realizing the transition from the rest state to the working state.

[0037] The rear check tooth 72 on the rear check wheel 7 in the working state extends through the check slot 51 into the check opening 121 at the top of the guide rail 12 below it, the rear first check stop surface 721 of the rear check tooth 72 in the check opening 121 is blocked by the rear stop portion 512 of the slot, the rear second check stop surface 722 is blocked by the inner wall of the check opening 121 located at the rear side relative to the movement direction of the sliding shoe mechanism 3, and the lower end of the rear first check stop surface 721 of the rear check tooth 72 in the check opening 121 is located above the check opening 121. The rear check tooth inclined surface 723 of the rear check tooth 72 in the check opening 121 extends obliquely upward from the check opening in the direction of the rear first check stop surface 721 from the lower end of the rear second check stop surface 722.

[0038] When the rear check wheel 7 is in working state, the piston rod of the hydraulic cylinder 41 retracts inwardly to pull the slipper mechanism 3 supporting the equipment to move backward in the slideway 10. Since the weight of the equipment is hundreds of tons, the piston rod of the hydraulic cylinder 41 then extends outward, which can drive the cylinder seat 42 to drive the hydraulic pump station mechanism 2 to move away from the slipper mechanism 3. During this process, the rear check tooth 72 can rotate out of one check port 121 and then fall into another check port.

[0039] When heavy equipment needs to be installed, several sliding rails of sliding devices are fixedly laid between the starting position and the target position to be installed. The number of sliding devices is set according to the size and weight of the heavy equipment. The heavy equipment to be installed is hoisted to the transport top cap 34 of the sliding shoe mechanism 3 of all sliding devices by large lifting equipment. The movement direction from the starting position to the target position is forward movement. The hydraulic pump station mechanism, sliding drive mechanism, and sliding shoe mechanism in each sliding device are arranged in sequence from the starting position to the target position. All front check wheels 6 are in working state, and the rear check wheels 7 are in rest state, see Figure 5 As shown. The piston rod of the hydraulic cylinder 41 in each sliding device extends outward, and then the sliding shoe mechanism 3 supporting the equipment is pushed forward synchronously. Then, the piston rods of all hydraulic cylinders 41 retract inward. Since the mass of the equipment is very large, the cylinder seat 42 can drive the hydraulic pump station mechanism 2 to move toward the sliding shoe mechanism 3, that is, the cylinder seat 42 drives the hydraulic pump station mechanism 2 to move forward. In this process, the front check tooth 62 rotates out of one check port 121 and falls into another check port. This process is repeated continuously, and the equipment continues to move toward the target position.

[0040] After reaching the target position, if the equipment needs to be adjusted in height, all the hydraulic jack plungers 331 will rise upward to lift the equipment to the desired position. When the hydraulic jack plungers 331 are lifted up to the desired position, the self-locking ring 37 on each hydraulic jack plunger 331 is rotated until it is blocked on the self-locking sleeve 38, thereby locking the hydraulic jack plunger 331. Even if the oil circuit is depressurized, it can be kept in the supporting position, thereby effectively ensuring the reliability of the hydraulic jack supporting. Afterwards, if the hydraulic jack plunger 331 needs to be lowered, the hydraulic jack plunger 331 will first rise up, and then the self-locking ring 37 will be rotated upward to a position that is disengaged from the self-locking sleeve 38, leaving enough margin for the hydraulic jack plunger 331 to descend.

[0041] If the equipment needs to be positioned in the lateral direction of the slide 10 , the double-axis hydraulic cylinders 39 in each sliding shoe mechanism 3 will move synchronously in the same direction, thereby driving each equipment support seat 32 to translate in the lateral direction of the corresponding sliding shoe base 31 .

[0042] The above working process is the process of sliding the heavy equipment from the outside to the required installation position. If the equipment needs to be moved out of the installation position for equipment inspection and maintenance, all the front check wheels 6 are turned into a resting state, and all the rear check wheels 7 are in a working state. The piston rods of all hydraulic cylinders 41 retract inwards to pull the sliding shoe mechanism 3 supporting the equipment to move backward in the slideway 10. Since the mass of the equipment is hundreds of tons, which is far greater than the mass of the hydraulic pump station mechanism 2 driven by the cylinder seat 42, the piston rod of the hydraulic cylinder 41 extends outwards, which can drive the cylinder seat 42 to drive the hydraulic pump station mechanism 2 to move away from the sliding shoe mechanism 3, that is, backward. In this process, the rear check tooth 72 can be rotated out of one check port 121 and then just fall into another check port. In this way, the heavy equipment is continuously moved outward.

[0043] During the above-mentioned action process, the hydraulic pump station mechanism 2 follows to provide hydraulic power for the hydraulic drive mechanisms in the entire sliding device, such as the hydraulic cylinder 41, the hydraulic jack 33, and the double-axle hydraulic cylinder 36, and control their actions.

[0044] From the above, it can be seen that: 1. The present invention application provides a sliding device, which provides a strong recoil force for the hydraulic cylinder 41 to push the heavy equipment forward or pull the heavy equipment backward to slide by setting the front check wheel 6 and the rear check wheel 7, ensuring that the equipment slides reliably, stably and safely. The front check wheel 6 and the rear check wheel 7 have a simple structure, and the switching operation between the working state and the rest state is very convenient. 2. The slide plates 101 are laid at intervals on the slide 10, which greatly improves the bearing capacity and wear resistance of the slide 10, ensuring that heavy equipment weighing hundreds of tons can slide smoothly to the target position. The intervals between the slide plates 101 can not only overcome the laying error of the slide 10, but also can be partially replaced in the event of damage, so that the sliding device can be reused many times, which not only greatly extends the service life, but also effectively reduces the cost of heavy equipment sliding.
