[0017] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0018] The present invention provides a hydraulic pump unit mechanism for an HGIS installation platform trolley. As Figures 1 to 5 shown, it includes a gantry structure 1, on which a power component and a traveling component are installed. The power component drives the traveling component, enabling the gantry structure 1 to move on the ground. The gantry structure 1 is welded by high-strength steel and consists of multiple hydraulic telescopic arms for lifting. It is installed on the side of the gantry structure 1 and can achieve the lifting action through a hydraulic control system. It can lift the GIS equipment to the required height, and the lifting is stable, accurate, and can hover at any height.

[0019] The power component includes an outer frame 2, a hydraulic pump unit 3, and an outer cover 4; the outer frame 2 is installed at the inner bottom of the gantry structure 1, and the hydraulic pump unit 3 is fixedly installed at the inner bottom of the outer frame 2. The outer cover 4 is composed of two opposite L-shaped plates, and the two L-shaped plates are cooperatively buckled on the top of the hydraulic pump unit 3. The inner side surface of the L-shaped plate is drivingly connected to the output end of the cylinder, and a moving component is installed on the outer side part of the L-shaped plate; when the cylinder works, the L-shaped plate moves, and the moving L-shaped plate approaches or moves away from the hydraulic pump unit 3 until the inner ends of the two L-shaped plates are mutually attached. At this time, the L-shaped plate forms the outer cover 4 and is buckled on the outer side part of the hydraulic pump unit 3 to complete the protection of the hydraulic pump unit 3.

[0020] The moving component includes a connecting rod 5, a moving block 6, side pipes 7, and insertion rods 8; the inner side surface of the moving block 6 is connected to the outer side surface of the L-shaped plate by the connecting rod 5. The inner ends of the two side pipes 7 are connected to the moving block 6. The insertion rods 8 are inserted into the side pipes 7, and the two insertion rods 8 are connected by a spring 9. A clamping component is fixed on the insertion rod 8. A plurality of side frames 10 are arranged at the inner bottom of the outer frame 2, and the elastic force of the spring 9 enables the clamping component to clamp on both sides of the side frame 10. When the L-shaped plate moves, the moving L-shaped plate makes the moving block 6 move on the top of the side frame 10 by means of the connecting rod 5, and the moving moving block 6 makes the insertion rod 8 move synchronously by means of the side pipe 7. Due to the elastic force of the spring 9, the insertion rod 8 drives the clamping component to approach the side frame 10, and the moving insertion rod 8 makes the clamping component slide on the side of the side frame 10. The clamping component ensures the smooth movement of the moving block 6.

[0021] In Figure 1 and Figure 2 the traveling component includes tires 11, tire brackets 12, a hydraulic drive motor, a hydraulic slewing bearing device, and a traveling hydraulic drive motor; the tire brackets 12 are installed on the tops of the tires 11, the traveling hydraulic drive motor is installed at the center of the tire brackets 12, the hydraulic slewing bearing device is installed on the tops of the tire brackets 12, the hydraulic drive motor is installed on the hydraulic slewing bearing device, and a diesel engine is also installed inside the outer frame 2. The diesel engine generates power to drive the hydraulic pump unit 3 to generate hydraulic energy to drive the whole vehicle to work. The hydraulic slewing bearing device enables the tire brackets 12 to drive the tires 11 to rotate 180 degrees. At this time, the hydraulic drive motor drives to enable the tire brackets 12 to drive the tires 11 to achieve slewing. The traveling hydraulic drive motor enables the vehicle to travel on the ground through the tires 11, and the gantry structure 1 can move forward, backward, and horizontally left and right. The overall design of the platform trolley enables it to make a U-turn in place, which is particularly important for operations in narrow spaces. In addition, the platform trolley can also travel horizontally, forward, and backward to achieve omnidirectional movement. These functions enable the platform trolley to flexibly respond in various construction sites. Whether it is a narrow construction area or a complex terrain that requires frequent turning, the platform trolley can easily handle it.

[0022] In Figure 3Among them, a plurality of empty slots are provided on the surface of the L-shaped plate, and a heat dissipation plate 13 is placed inside the empty slots. When the cylinder works, the output end of the cylinder causes the L-shaped plate to approach the hydraulic pump unit 3, and the two L-shaped plates cooperate to clamp the hydraulic pump unit 3. The heat dissipation plate 13 is arranged as a grid plate, and the moving component makes the inner side surface of the heat dissipation plate 13 fit with the side surface of the hydraulic pump unit 3. When the two L-shaped plates cooperate to clamp the hydraulic pump unit 3, at this time the moving component makes the inner side surface of the heat dissipation plate 13 squeeze the hydraulic pump unit 3, and the heat generated by the operation of the hydraulic pump unit 3 is dissipated through the plurality of heat dissipation plates 13. When the L-shaped plate is far away from the hydraulic pump unit 3, the moving component pulls the heat dissipation plate 13 out of the empty slot, the hydraulic pump unit 3 does not contact the L-shaped plate, and the hydraulic pump unit 3 dissipates heat through the empty slot, and the hydraulic pump unit 3 directly exchanges heat with the outside air, which is convenient for efficient heat dissipation.

[0023] In Figures 3 to 5 Among them, the moving component further includes a vertical rod 14, a vertical tube 15, a toothed ring 16 and a side plate 17; the center of the vertical tube 15 is fixedly connected to the insertion rod 8, and the vertical rod 14 is inserted through the inside of the vertical tube 15. A side plate 17 is installed on the inner side of the bottom end of the vertical tube 15, the top surface of the side plate 17 fits with the bottom surface of the side of the side frame 10, the toothed ring 16 is sleeved on the surface of the vertical tube 15, the bottom surface of the toothed ring 16 fits with the top surface of the side plate 17, and the top surface of the toothed ring 16 fits with the surface of the side tube 7. A plurality of teeth 18 are provided on the outer side surface of the side of the side frame 10, and the toothed ring 16 meshes with the side of the side frame 10 through the plurality of teeth 18. A chute corresponding to the vertical tube 15 is provided on the surface of the side tube 7. Pull the vertical tube 15 to move inside the chute, and the moving vertical tube 15 drives the insertion rod 8 to move synchronously. When the two insertion rods 8 are separated from each other, the two separated insertion rods 8 cooperate to pull the spring 9. When the distance between the two side plates 17 is greater than the width of the side frame 10, the moving block 6 is placed on the top of the side frame 10, and the inner end of the connecting rod 5 is fixed to the outer side surface of the L-shaped plate by welding.

[0024] Release the pulling force applied to the vertical tube 15, and the elastic force of the spring 9 makes the two insertion rods 8 approach each other. The moving insertion rod 8 uses the vertical tube 15 to make the vertical rod 14 drive the side plate 17 to approach the side frame 10 until the top surface of the side plate 17 fits with the bottom surface of the side of the side frame 10. At this time, the toothed ring 16 on the surface of the vertical tube 15 meshes with the teeth 18 on the side.

[0025] When the L-shaped plate makes the moving block 6 move by using the connecting rod 5, the moving moving block 6 uses the side tube 7 to make the insertion rod 8 drive the vertical tube 15 to move synchronously. The moving insertion rod 8 uses the vertical tube 15 to drive the toothed ring 16 to rotate on the surface of the teeth 18, and the rotation of the toothed ring 16 is used to avoid frictional damage between the vertical tube 15 and the side of the side frame 10.

[0026] In Figure 4 and Figure 5Among them, the moving part further includes a rotating plate 19, a top ring 20, side rods 21 and a convex edge 22; the side rods 21 are horizontally arranged, the outer ends of the side rods 21 are fixed to the top of the vertical rod 14, the two side rods 21 are arranged oppositely, the top ring 20 is sleeved on the inner ends of the two side rods 21, the top ring 20 is fixedly installed on the top of the rotating plate 19, the convex edge 22 is fixed on the surface of the vertical rod 14, a vertical groove 23 corresponding to the convex edge 22 is arranged on the surface of the vertical pipe 15, and the outer side surface of the convex edge 22 is in spiral fit with the inner side wall of the toothed ring 16. The rotating toothed ring 16 causes the convex edge 22 to move up and down inside the vertical groove 23. A collar 24 is arranged on the surface of the connecting rod 5, a limiting rod 25 is fixed to the top of the collar 24, and the bottom end of the rotating plate 19 is sleeved on the surface of the limiting rod 25. The moving vertical pipe 15 causes the toothed ring 16 to rotate on the side teeth 18. Since the inner side wall of the toothed ring 16 is spirally sleeved on the outer side surface of the convex edge 22, the rotation of the toothed ring 16 causes the convex edge 22 to move up and down inside the vertical groove 23.

[0027] When the L-shaped plate moves away from the hydraulic pump set 3, the L-shaped plate uses the connecting rod 5 to move the moving block 6. At this time, the side pipe 7 and the inserting rod 8 cooperate to make the vertical pipe 15 drive the toothed ring 16 to rotate on the surface of the teeth 18. The spiral fit between the rotating toothed ring 16 and the convex edge 22 causes the convex edge 22 to move upward inside the vertical groove 23. The upward moving convex edge 22 drives the vertical rod 14 to move upward inside the vertical pipe 15. The upward moving vertical rod 14 uses the side rod 21 to move the top ring 20 upward. The upward moving top ring 20 uses the rotating plate 19 to pull the collar 24 to slide on the surface of the connecting rod 5. The moving collar 24 uses the connecting component to quickly pull out the heat dissipation plate 13 from the empty groove, which is convenient for efficiently dissipating heat from the hydraulic pump set 3.

[0028] When the L-shaped plate approaches the hydraulic pump set 3, the spiral fit between the rotating toothed ring 16 and the convex edge 22 causes the convex edge 22 to move downward inside the vertical groove 23. The downward moving convex edge 22 drives the vertical rod 14 to move downward inside the vertical pipe 15. The downward moving vertical rod 14 uses the side rod 21 to move the top ring 20 downward. The downward moving top ring 20 uses the rotating plate 19 to push the collar 24 to slide on the surface of the connecting rod 5. The moving collar 24 uses the connecting component to push the heat dissipation plate 13 into the empty groove, and the moving part uses the heat dissipation plate 13 to limit the hydraulic pump set 3, further ensuring the stability of the hydraulic pump set 3.

[0029] During the process of the L-shaped plate moving away from the hydraulic pump set 3, the bottom surface of the horizontal plate of the L-shaped plate always fits on the top surface of the hydraulic pump set 3, ensuring the stability of the hydraulic pump set 3 during the heat dissipation process.

[0030] In Figure 3 、 Figure 6 and Figure 7Among them, the collar 24 is connected to the outer side surface of the heat dissipation plate 13 by a connecting component. The connecting component includes a bent rod 26, a rotating sleeve 27 and a screw rod 28. The screw rod 28 is fixedly installed on the outer side surface of the heat dissipation plate 13. The inner end of the rotating sleeve 27 is spirally sleeved on the surface of the screw rod 28, and the outer end of the rotating sleeve 27 is rotationally matched with the inner end of the bent rod 26. Align the inner end of the bent rod 26 with the screw rod 28 and rotate the rotating sleeve 27. The inner end of the rotating sleeve 27 is spirally sleeved on the surface of the screw rod 28, completing the connection between the collar 24 and the heat dissipation plate 13. At this time, the moving collar 24 makes the heat dissipation plate 13 move synchronously by means of the connecting component.

[0031] Working principle of the present invention: Refer to Figures 1 to 7 As shown, pull the vertical pipe 15 to move inside the chute. The moving vertical pipe 15 drives the insertion rod 8 to move synchronously. When the two insertion rods 8 are separated from each other, the two separated insertion rods 8 cooperate to pull the spring 9. When the distance between the two side plates 17 is greater than the width of the side frame 10, place the moving block 6 on the top of the side frame 10 and fix the inner end of the connecting rod 5 to the outer side surface of the L-shaped plate by welding.

[0032] Release the pulling force applied to the vertical pipe 15. The elastic force of the spring 9 makes the two insertion rods 8 approach each other. The moving insertion rods 8 drive the vertical rod 14 to drive the side plate 17 to approach the side frame 10 by means of the vertical pipe 15 until the top surface of the side plate 17 is in contact with the bottom surface of the side of the side frame 10. At this time, the toothed ring 16 on the surface of the vertical pipe 15 is meshed and matched with the tooth teeth 18 on the side.

[0033] The air cylinder works. The output end of the air cylinder makes the L-shaped plate approach the hydraulic pump group 3. The two L-shaped plates cooperate to clamp the hydraulic pump group 3. When the two L-shaped plates cooperate to clamp the hydraulic pump group 3, at this time, the moving component makes the inner side surface of the heat dissipation plate 13 press against the hydraulic pump group 3. The heat generated by the operation of the hydraulic pump group 3 is dissipated through a plurality of heat dissipation plates 13. When the L-shaped plate moves away from the hydraulic pump group 3, the moving component pulls the heat dissipation plate 13 out of the empty slot. The hydraulic pump group 3 is not in contact with the L-shaped plate, and the hydraulic pump group 3 dissipates heat through the empty slot. The hydraulic pump group 3 is directly in contact with the outside air for heat exchange, which is convenient for efficient heat dissipation.

[0034] When the L-shaped plate moves away from the hydraulic pump group 3, the L-shaped plate drives the moving block 6 to move by means of the connecting rod 5. At this time, the side pipe 7 and the insertion rod 8 cooperate to make the vertical pipe 15 drive the toothed ring 16 to rotate on the surface of the tooth teeth 18. The spiral cooperation between the rotating toothed ring 16 and the convex edge 22 makes the convex edge 22 move upward in the vertical groove 23. The upward moving convex edge 22 drives the vertical rod 14 to move upward inside the vertical pipe 15. The upward moving vertical rod 14 makes the top ring 20 move upward by means of the side rod 21. The upward moving top ring 20 pulls the collar 24 to slide on the surface of the connecting rod 5 by means of the rotating plate 19. The moving collar 24 quickly pulls the heat dissipation plate 13 out of the empty slot by means of the connecting component, which is convenient for efficient heat dissipation of the hydraulic pump group 3.

[0035] When the L-shaped plate approaches the hydraulic pump unit 3, the spiral fit between the rotating toothed ring 16 and the convex edge 22 causes the convex edge 22 to move downward inside the vertical groove 23. The downward-moving convex edge 22 drives the vertical rod 14 to move downward inside the vertical pipe 15. The downward-moving vertical rod 14 uses the side rod 21 to cause the top ring 20 to move downward. The downward-moving top ring 20 uses the rotating plate 19 to push the collar 24 to slide on the surface of the connecting rod 5. The moving collar 24 uses the connecting component to push the heat dissipation plate 13 into the empty groove, and the moving component uses the heat dissipation plate 13 to limit the hydraulic pump unit 3, further ensuring the stability of the hydraulic pump unit 3. During the process when the L-shaped plate moves away from the hydraulic pump unit 3, the bottom surface of the horizontal plate of the L-shaped plate always fits against the top surface of the hydraulic pump unit 3, ensuring the stability of the hydraulic pump unit 3 during the heat dissipation process.

[0036] The diesel engine generates power to drive the hydraulic pump unit 3 to generate hydraulic energy to drive the whole vehicle to work. The hydraulic slewing bearing device enables the tire bracket 12 to drive the tire 11 to rotate 180 degrees. At this time, the hydraulic drive motor drives to enable the tire bracket 12 to drive the tire 11 to achieve slewing. The traveling hydraulic drive motor walks on the ground through the tire 11, and can enable the gantry frame 1 to move forward, backward, left and right horizontally.

[0037] The above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them.
