Description

Technical Field

[0001] The present invention belongs to the technical field of auxiliary equipment for pole-mounted transformers, and particularly relates to a portable quick transportation and lifting device for pole-mounted transformers. Background Art

[0002] Power transformers are one of the main equipment in power plants and substations, and are used to change alternating current voltage and current of a certain value into another or several different values of alternating current voltage and current with the same frequency. The installation of pole-mounted transformers usually fixes the cross arm between two electric poles as a support frame, and then slowly hoists the transformer onto the support frame for installation. Traditional methods for transporting and lifting transformers mainly rely on large-scale lifting equipment and manual operations. Large-scale lifting equipment has a large construction radius, which affects the safety of adjacent power lines and traffic; at the same time, the boom length is relatively large, and it is usually difficult to effectively operate above the support frame, and it is more suitable for use in open fields or main roads in the wild. However, some installation support frames are located in narrow areas such as streets, communities, fields, and mountains, where large-scale lifting equipment cannot reach. When using manual operations, multiple people need to cooperate, and the operation is complex, which not only has low efficiency but also poses safety hazards. Summary of the Invention

[0003] The purpose of the present invention is to overcome the deficiencies of the prior art, and to provide a portable quick transportation and lifting device for pole-mounted transformers that is easy to move, convenient to install, safe and reliable.

[0004] The purpose of the present invention is achieved as follows: A portable quick transportation and lifting device for pole-mounted transformers, which includes a transfer vehicle. There is a support platform above the transfer vehicle, and a lifting bracket is arranged between the support platform and the transfer vehicle. A transformer is placed on the upper side of the support platform. A vertical shaft is fixedly arranged on the left side of the support platform, and a cross bar is arranged at the upper end of the vertical shaft. A chute is arranged at the bottom of the cross bar. A translation motor is fixedly arranged at the left end of the chute. The output end of the translation motor is provided with a translation screw rod. The translation screw rod is located inside the chute. A sliding sleeve is threadedly connected to the outside of the translation screw rod. A hanging plate is arranged between the sliding sleeves. An electric winch is arranged on the upper side of the hanging plate. A winch rope is wound around the outside of the electric winch. A hook is arranged at the end of the winch rope.

[0005] Legs are arranged on the side of the transfer vehicle, and sleeves are arranged at the ends of the legs. A stabilizing foot is threadedly connected inside the sleeves.

[0006] A limiting frame is arranged on the upper side of the support platform, and a clamping spring is arranged between the limiting frame and the support platform.

[0007] Two limiting frames are symmetrically arranged, and the shape of the limiting frame is "匚".

[0008] A shifting mechanism is provided on the upper side of the vertical shaft. The shifting mechanism includes a top rod and a pull plate. The top rod is fixed to the upper end of the vertical shaft and has an inner hole. A side groove is provided on the right side of the top rod. A head rod is provided at the left end of the horizontal rod and is located inside the inner hole. The pull plate is located in the middle of the hanging plate and has a hollow structure inside. The pull plate is movably connected to the hanging plate.

[0009] The top rod has a top edge groove on its upper side, and a positioning screw is fixedly installed on the upper side of the head rod. The positioning screw extends out from the top edge groove, and a throttle is screwed onto the outer side of the positioning screw.

[0010] Both the inner hole and the head rod have a square cross-sectional shape.

[0011] A clamping mechanism is provided on the outside of the crossbar. The clamping mechanism includes a clamping screw and a clamping claw. The inner end of the clamping screw is connected to the inside of the crossbar through a bearing. A handle is provided on the outer end of the clamping screw. A sleeve is symmetrically screwed to the outside of the clamping screw. A clamping claw is fixedly provided on the outside of the sleeve.

[0012] The two jackets have internal threads in opposite directions.

[0013] The beneficial effects of this invention are as follows: The combined design of the transfer cart, platform, and lifting bracket enables the transformer to be loaded and unloaded quickly and smoothly, improving transportation and installation efficiency. The stable structure formed by the vertical shaft and horizontal bar, along with the precise control of the slide and translation motor, allows the suspended platform to move smoothly, ensuring the stability of the transformer during movement and reducing the risk of swaying and tilting. The combined use of the electric winch and winch rope makes the lifting process faster and more evenly forceful, effectively shortening the lifting time, reducing reliance on manual operation, and alleviating labor intensity. The design of the shifting mechanism, including components such as the top rod, head rod, and pull-out plate, allows the width of the horizontal bar and suspended platform to be flexibly adjusted according to actual needs, meeting the requirements of different spacing platforms. The clamping mechanism, through the cooperation of the clamping screw and the jaws, can be fixedly connected to the pole, further enhancing the stability of the device. The folding and telescopic design of components such as the transfer cart, lifting bracket, and shifting mechanism allows the device to be easily folded when not in use, reducing its size and facilitating carrying and storage. This invention has the advantages of being easy to move, convenient to install, and safe and reliable. Attached Figure Description

[0023] like Figure 1-5 As shown, a portable pole-mounted transformer rapid transport and lifting device includes a transfer vehicle 1, a support platform 2 on top of the transfer vehicle 1, a lifting bracket 3 between the support platform 2 and the transfer vehicle 1, a transformer 4 placed on the support platform 2, a vertical shaft 5 fixedly installed on the left side of the support platform 2, a horizontal bar 6 at the upper end of the vertical shaft 5, a sliding groove 7 at the bottom of the horizontal bar 6, a translation motor 8 fixedly installed at the left end of the sliding groove 7, a translation screw 9 at the output end of the translation motor 8, the translation screw 9 located inside the sliding groove 7, a sliding sleeve 10 screwed to the outside of the translation screw 9, a lifting plate 11 between the sliding sleeves 10, an electric winch 12 on the upper side of the lifting plate 11, a winch rope 13 wound around the outside of the electric winch 12, and a hook 14 at the end of the winch rope 13.

[0024] The transfer vehicle 1 is provided with a support leg 15 on one side, and a sleeve 16 is provided at the end of the support leg 15. A stabilizing foot 17 is screwed into the sleeve 16.

[0025] A limiting frame 18 is provided on the upper side of the support table 2, and a clamping spring 19 is provided between the limiting frame 18 and the support table 2.

[0026] There are two symmetrically arranged limiting frames 18, and the shape of the limiting frame 18 is "C" shaped.

[0027] When the present invention is in use, ensure that components such as the transfer vehicle 1, the support table 2, and the lifting bracket 3 are in good condition, check whether components such as the winch rope 13 and the hook 14 are firm, without wear or fracture, and confirm that components such as the support leg 15, the sleeve 16, and the stabilizing foot 17 can be normally telescoped and fixed. Place the transformer 4 on the upper side of the support table 2, and clamp and limit the transformer 4 through the limiting frame 18 to prevent the transformer 4 from shaking when the transfer vehicle 1 is running. Move the transfer vehicle 1 to the position where the transformer 4 needs to be lifted, adjust the position of the support leg 15 according to the terrain, and support the transfer vehicle 1 on the ground through the stabilizing foot 17. Connect the hook 14 to the lifting ring of the transformer 4 or other suitable lifting points through the winch rope 13 wound around the outside of the electric winch 12. Adjust the height of the lifting bracket 3 to ensure that the support table 2 smoothly carries the transformer 4 and rises to the installation height. Operate the electric winch 12 to gradually lift the transformer 4 to the required height, drive the translation screw 9 to rotate in the chute 7 through the output end of the translation motor 8, so as to drive the sliding sleeve 10 and the hanging plate 11 to move along the chute 7 to a suitable position. Operate the electric winch 12 again to gradually lower the transformer 4 to the specified position, ensuring that the transformer 4 falls smoothly. This device not only improves the efficiency and safety of the transportation and lifting operations of the transformer, but also enhances the flexibility and adaptability of the device, simplifies the operation process and reduces the labor intensity.

[0029] For better effect, a support leg 15 is provided on the side of the transporter 1. A sleeve 16 is provided at the end of the support leg 15, and a stabilizing foot 17 is screwed inside the sleeve 16. The design of the support leg 15 on the side of the transporter 1 and the stabilizing foot 17 inside the sleeve 16 effectively improves the stability of the transporter during hoisting operations.

[0030] For better effect, a limiting frame 18 is provided on the upper side of the support table 2, and a clamping spring 19 is provided between the limiting frame 18 and the support table 2. It ensures that the transformer 4 is tightly fixed on the support table 2 during transportation, further enhancing safety.

[0031] For better effect, two limiting frames 18 are symmetrically provided, and the limiting frame 18 is in the shape of a "C".

[0032] For better effect, a displacement mechanism is provided on the upper side of the vertical shaft 5. The displacement mechanism includes a top rod 20 and a draw plate 27. The top rod 20 is fixed to the upper end of the vertical shaft 5. An inner hole 21 is provided inside the top rod 20, and a side groove 22 is provided on the right side of the top rod 20. A head rod 23 is provided at the left end of the cross bar 6, and the head rod 23 is located inside the inner hole 21. The draw plate 27 is located in the middle of the hanging plate 11. The inside of the hanging plate 11 is a hollow structure, and the draw plate 27 is movably connected to the hanging plate 11.

[0033] For better effect, a top side groove 24 is provided on the upper side of the top rod 20. A positioning screw 25 is fixedly provided on the upper side of the head rod 23. The positioning screw 25 extends out of the top side groove 24, and a turning handle 26 is screwed outside the positioning screw 25. By rotating the turning handle 26, the turning handle 26 can be brought into close contact with the top rod 20, thereby positioning the head rod 23.

[0034] For better effect, the cross-sectional shapes of the inner hole 21 and the head rod 23 are both square. This shape can increase the fit between the head rod 23 and the inner hole 21 and prevent the head rod 23 from rotating inside the inner hole 21.

[0035] When using this invention, ensure that components such as the transfer cart 1, platform 2, and lifting bracket 3 are intact. Check that components such as the winch rope 13 and hook 14 are secure and free from wear or breakage. Confirm that components such as the outriggers 15, sleeves 16, and stabilizing feet 17 can extend, retract, and be fixed normally. Place the transformer 4 on the platform 2 and clamp and limit the transformer 4 using the limiting frame 18 to prevent the transformer 4 from shaking during the operation of the transfer cart 1. Move the transfer cart 1 to the position where the transformer 4 needs to be lifted. Adjust the position of the outriggers 15 according to the terrain and support the transfer cart 1 on the ground using the stabilizing feet 17. Connect the hook 14 to the lifting ring of the transformer 4 or other suitable lifting point using the winch rope 13 wound around the outside of the electric winch 12. Adjust the height of the lifting bracket 3 to ensure that the platform 2 smoothly lifts the transformer 4 to the installation height. Operate the electric winch 12 to gradually lift the transformer 4 to the required height. The output of the translation motor 8 drives the translation screw 9 to rotate within the slide groove 7, thereby moving the sliding sleeve 10 and the hanging plate 11 along the slide groove 7 to the appropriate position. Operate the electric winch 12 again to gradually lower the transformer 4 to the designated position, ensuring a smooth descent. Furthermore, to facilitate use between poles with different spacing, a displacement mechanism is provided on the upper side of the vertical shaft 5. Specifically, the throttle 26 moves the positioning screw 25 within the top edge groove 24, which in turn moves the crossbar 6 via the head rod 23. The distance between the two crossbars 6 is adjusted according to the pole spacing. After adjustment, tighten the throttle 26 to fix the positioning screw 25 within the top edge groove 24, thus fixing the position of the two crossbars 6. The lifting platform 11 is hollow, and the pull-out plate 27 is inserted into the lifting platform 11. The pull-out plate 27 moves with the crossbar 6 to adjust the length of the lifting platform 11, so that the electric winch 12 is always located in the middle position of the lifting platform 11. This device not only improves the efficiency and safety of transformer transportation and lifting operations, but also enhances the flexibility and adaptability of the device, simplifies the operation process, and reduces labor intensity. Example

[0036] like Figure 1-7 As shown, a portable pole-mounted transformer rapid transport and lifting device includes a transfer vehicle 1, a support platform 2 on top of the transfer vehicle 1, a lifting bracket 3 between the support platform 2 and the transfer vehicle 1, a transformer 4 placed on the support platform 2, a vertical shaft 5 fixedly installed on the left side of the support platform 2, a horizontal bar 6 at the upper end of the vertical shaft 5, a sliding groove 7 at the bottom of the horizontal bar 6, a translation motor 8 fixedly installed at the left end of the sliding groove 7, a translation screw 9 at the output end of the translation motor 8, the translation screw 9 located inside the sliding groove 7, a sliding sleeve 10 screwed to the outside of the translation screw 9, a lifting plate 11 between the sliding sleeves 10, an electric winch 12 on the upper side of the lifting plate 11, a winch rope 13 wound around the outside of the electric winch 12, and a hook 14 at the end of the winch rope 13.

[0037] For better effect, legs 15 are provided on the side of the transporter 1, sleeves 16 are provided at the ends of the legs 15, and stabilizing feet 17 are screwed inside the sleeves 16. The design of the legs 15 on the side of the transporter 1 and the stabilizing feet 17 inside the sleeves 16 effectively improves the stability of the transporter during hoisting operations.

[0038] For better effect, a limiting frame 18 is provided on the upper side of the support table 2, and a clamping spring 19 is provided between the limiting frame 18 and the support table 2. It ensures that the transformer 4 is tightly fixed on the support table 2 during transportation, further enhancing safety.

[0039] For better effect, two limiting frames 18 are symmetrically provided, and the shape of the limiting frame 18 is "C"-shaped.

[0040] For better effect, a displacement mechanism is provided on the upper side of the vertical shaft 5. The displacement mechanism includes a top rod 20 and a pull-out plate 27. The top rod 20 is fixed to the upper end of the vertical shaft 5. An inner hole 21 is provided inside the top rod 20. A side groove 22 is provided on the right side of the top rod 20. A head rod 23 is provided at the left end of the cross bar 6. The head rod 23 is located inside the inner hole 21. The pull-out plate 27 is located in the middle of the hanging plate 11. The inside of the hanging plate 11 is a hollow structure. The pull-out plate 27 is movably connected to the hanging plate 11.

[0041] For better effect, a top side groove 24 is provided on the upper side of the top rod 20. A positioning screw 25 is fixedly provided on the upper side of the head rod 23. The positioning screw 25 extends out from the top side groove 24. A rotating handle 26 is screwed outside the positioning screw 25. By rotating the rotating handle 26, the rotating handle 26 can be in close contact with the top rod 20, and then the head rod 23 can be positioned.

[0042] For better effect, the cross-sectional shapes of the inner hole 21 and the head rod 23 are both square. This shape can increase the fit between the head rod 23 and the inner hole 21 and prevent the head rod 23 from rotating inside the inner hole 21.

[0043] For better effect, a clamping mechanism is provided on the outside of the cross bar 6. The clamping mechanism includes a clamping screw 28 and a clamping jaw 31. The inner end of the clamping screw 28 is connected to the inside of the cross bar 6 through a bearing. A handle 29 is provided at the outer end of the clamping screw 28. Clamping sleeves 30 are symmetrically screwed outside the clamping screw 28. Clamping jaws 31 are fixedly provided on the outside of the clamping sleeves 30.

[0044] For better effect, the thread directions inside the two clamping sleeves 30 are opposite. When the clamping screw 28 rotates, it can drive the two clamping sleeves 30 to approach or move away from each other.

[0045] When using this invention, ensure that components such as the transfer cart 1, platform 2, and lifting bracket 3 are intact. Check that components such as the winch rope 13 and hook 14 are secure and free from wear or breakage. Confirm that components such as the outriggers 15, sleeves 16, and stabilizing feet 17 can extend, retract, and be fixed normally. Place the transformer 4 on the platform 2 and clamp and limit the transformer 4 using the limiting frame 18 to prevent the transformer 4 from shaking during the operation of the transfer cart 1. Move the transfer cart 1 to the position where the transformer 4 needs to be lifted. Adjust the position of the outriggers 15 according to the terrain and support the transfer cart 1 on the ground using the stabilizing feet 17. Connect the hook 14 to the lifting ring of the transformer 4 or other suitable lifting point using the winch rope 13 wound around the outside of the electric winch 12. Adjust the height of the lifting bracket 3 to ensure that the platform 2 smoothly lifts the transformer 4 to the installation height. Operating the electric winch 12, the transformer 4 is gradually lifted to the required height. The output of the translation motor 8 drives the translation screw 9 to rotate within the slide groove 7, thereby moving the sliding sleeve 10 and the lifting plate 11 along the slide groove 7 to the appropriate position. The electric winch 12 is operated again to gradually lower the transformer 4 to the designated position, ensuring a smooth descent. Furthermore, to increase the stability of the crossbar 6, a clamping mechanism is installed on the outside of the crossbar 6. When the crossbar 6 moves near the pole, the clamping jaws 31 are placed on the outside of the pole, and the handle 29 is rotated to continue rotating the clamping screw 28. Since the threads inside the two sleeves 30 are in opposite directions, the rotation of the clamping screw 28 will cause the two sleeves 30 to move towards each other, thereby clamping the pole through the clamping jaws 31. As needed, the force of rotating the handle 29 can be gradually increased to make the clamping jaws 31 grip the object more firmly. This device not only improves the efficiency and safety of transformer transportation and lifting operations but also enhances the flexibility and adaptability of the device, simplifies the operation process, and reduces labor intensity.
