Description

Technical Field

[0001] The present invention relates to the technical field of manual hoisting and transportation equipment, and specifically to a transformer transportation device with an auxiliary loading and unloading structure. Background Art

[0002] For some small transformers, their installation positions are relatively narrow, and large lifting equipment or forklifts are inconvenient to move. Generally, small manual equipment is used to transport transformers, such as manual hanging frames (cantilever cranes) or manual forklifts. The hooks on the transformers are located at the four corner positions, and for safety considerations, the inclination angle of the lifting ropes generally needs to be controlled within 15 degrees. As a result, when the manual hanging frame lifts the transformer from directly above, the height requirement of the hanging frame is relatively high, which is not convenient for transportation in indoor or other positions with limited height. When using a manual forklift for transportation, although the height is generally not limited, a pallet needs to be set under the transformer, and when unloading, the transformer directly falls on the pallet, resulting in the need to unload the transformer from the pallet later, which is rather inconvenient. Summary of the Invention

[0003] The purpose of the present invention is to provide a transformer transportation device with an auxiliary loading and unloading structure to solve the problems raised in the above background art.

[0004] To achieve the above purpose, the present invention provides the following technical solutions:

[0005] A transformer transportation device with an auxiliary loading and unloading structure, comprising:

Between the central seat rod and the lateral seat rods are rotatably connected two parallel linkages, and the two parallel linkages on the same side are parallel to each other. The central seat rod is parallel to the lateral seat rods. At both ends of the top surface of the lateral seat rods are fixedly connected vertical frames, and between the tops of the two vertical frames on the same side is fixedly connected a first support roller. At both ends of the first support roller are provided traction ropes, and one end of each traction rope is fixedly connected with a hook;

[0007] Two winch assemblies, which are respectively arranged at the top surface positions of the two lateral seat rods, and the winch assemblies are used to traction the other ends of the two traction ropes on the same side;

[0008] Four adjustment assemblies, which are respectively fixed on the four vertical frames, and the adjustment assemblies are used to squeeze and adjust the adjacent traction ropes.

[0009] Furthermore: At both ends of the outer side wall of the first support roller are rotatably sleeved with first guide wheels, and the traction ropes are wound around the adjacent first guide wheels.

[0010] Furthermore, the top end of the vertical frame inclines to one side. The first support roller is located at the top end of the vertical frame. A second support roller is arranged on one side of the first support roller. Both ends of the second support roller are rotatably connected to the top ends of the adjacent vertical frames.

[0011] Furthermore, the hoisting assembly includes a second lead screw. The second lead screw is rotatably installed on the lateral seat rod. One end of the second lead screw is in threaded connection with a traction head. A limiting groove is formed in the top surface of the lateral seat rod corresponding to the position of the second lead screw. The bottom end of the traction head is slidably connected to the inner wall of the limiting groove. The other end of the traction rope is fixedly connected to the adjacent traction head.

[0012] Furthermore, the hoisting assembly further includes two second guide wheels. The two second guide wheels are respectively rotatably installed on one side wall of the bottom ends of the two vertical frames. One end of the top surface of the lateral seat rod is rotatably connected to a third guide wheel. The middle position of the top surface of the lateral seat rod is rotatably connected to a fourth guide wheel. The other end of one of the two traction ropes on the same side bypasses a second guide wheel and is fixedly connected to the traction head. And the other end of the other traction rope successively bypasses the other second guide wheel, the third guide wheel and the fourth guide wheel and is fixedly connected to the traction head.

[0013] Furthermore, a sleeve is fixedly connected to the other end of the second lead screw.

[0014] Furthermore, universal wheels are installed at both ends of the bottom side of the lateral seat rod and the bottom side of the central seat rod. One end of the central seat rod is rotatably installed with a first double-axis connecting seat. The top end of the first double-axis connecting seat is rotatably connected to a traction rod.

[0015] Furthermore, the adjusting assembly includes a first fixing seat and a second fixing seat. The first fixing seat and the second fixing seat are both fixedly connected to the adjacent vertical frame. A first lead screw is rotatably connected between one ends of the first fixing seat and the second fixing seat. One end of the first fixing seat is rotatably connected to a first bracket. One end of the first bracket is rotatably sleeved with a wheel axle. A second bracket is arranged above the first bracket. The bottom end of the second bracket is rotatably sleeved with the wheel axle. The bottom end of the second bracket is rotatably connected to a threaded sleeve. The threaded sleeve is in threaded connection with the first lead screw. An extrusion wheel is rotatably sleeved on the outer side wall of the wheel axle.

[0016] Furthermore, a support module is arranged between the other ends of the two lateral seat rods. The support module is used for limiting the distance between the two lateral seat rods.

[0017] Furthermore, the support module includes a double-axis connecting seat II and a U-shaped clamping seat. The bottom end of the double-axis connecting seat II is rotatably connected to the top surface of the other end of a lateral seat rod. The U-shaped clamping seat is fixedly installed at the other end of the other lateral seat rod. The top end of the double-axis connecting seat II is rotatably connected to a support rod. A threaded groove is provided at one end of the support rod, and two oppositely arranged limit seats are screwed to the other end of the support rod.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0019] 1. Through the arrangement of four towing ropes, the four top corners of the transformer are lifted by the four towing ropes. The tightening amplitude of the corresponding towing ropes is adjusted through the adjustment assembly, so as to adjust the four towing ropes, so that the transformer remains horizontal after being lifted. By adjusting the distance between the two lateral seat rods, it is convenient to lift and transfer transformers of different sizes, and there is no need to set a tray at the bottom of the transformer, and the overall height of the device is relatively low, which is convenient for indoor transfer or transfer into the room;

[0020] 2. Through the arrangement of the adjustment assembly, manually rotate the first lead screw. The first lead screw drives the threaded sleeve to move up and down, so as to drive the pressing wheel to move away from or close to the first lead screw through the second bracket and the first bracket. When the pressing wheel moves away from the first lead screw, it presses the middle position of the towing rope, so that the part of the towing rope between the second support roller and the second guide wheel is bent, thereby improving the tension of the towing rope and realizing the adjustment of the tension of a single towing rope, which is convenient for leveling the lifted transformer.

Detailed implementation manners

[0028] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0029] Please refer to Figures 1 to 4, in the embodiment of the present invention, a transformer transportation device with an auxiliary loading and unloading structure includes a chassis assembly 100, an adjustment assembly 200 and a hoisting assembly 300. The chassis assembly 100 includes a central seat rod 110. On both sides of the central seat rod 110, there are lateral seat rods 120. Between the central seat rod 110 and the lateral seat rods 120, there are two parallel link rods 130 rotatably connected. And the two parallel link rods 130 on the same side are parallel to each other. The central seat rod 110 is parallel to the lateral seat rods 120. At both ends of the top surface of the lateral seat rod 120, there are vertical frames 140 fixedly connected. And between the tops of the two vertical frames 140 on the same side, there is a first support roller 141 fixedly connected. At both ends of the first support roller 141, there are traction ropes 150. One end of the traction rope 150 is fixedly connected with a hook 151. There are two hoisting assemblies 300, and the two hoisting assemblies 300 are respectively arranged at the top surface positions of the two lateral seat rods 120. The hoisting assembly 300 is used to traction the other ends of the two traction ropes 150 on the same side. There are four adjustment assemblies 200, and the four adjustment assemblies 200 are respectively fixed on the four vertical frames 140. The adjustment assembly 200 is used to squeeze and adjust the adjacent traction rope 150. At both ends of the outer side wall of the first support roller 141, there are first guiding wheels 142 rotatably sleeved. The traction rope 150 is wound around the adjacent first guiding wheel 142. The top end of the vertical frame 140 is inclined to one side. The first support roller 141 is located at the top end position of the vertical frame 140. On one side of the first support roller 141, there is a second support roller 143. Both ends of the second support roller 143 are rotatably connected with the top ends of the adjacent vertical frames 140.

[0030] Specifically, expand the lateral seat rods 120 to both sides so that the transformer is located between the two lateral seat rods 120. Connect the hooks at the four top corners of the transformer by the hooks 151 at one end of the four traction ropes 150. Tighten the other ends of the two traction ropes 150 on the same side by the hoisting assembly 300, so as to lift the transformer. Adjust the tightening amplitude of the corresponding traction rope 150 by the adjustment assembly 200, so as to adjust the four traction ropes 150, so that the transformer remains horizontal after being lifted. By adjusting the distance between the two lateral seat rods 120, it is convenient to lift and transfer transformers of different sizes. In addition, through the adjustable setting of the distance between the two lateral seat rods 120, one end of the traction rope 150 is in a vertical state when being lifted, realizing the vertical lifting of the transformer by the traction rope 150, and avoiding the influence on the distance between the two lateral seat rods 120 caused by the pulling force of the transformer on the traction rope 150 when one end of the traction rope 150 is inclined. By lifting and transferring the transformer by the traction rope 150, there is no need to set a tray at the bottom of the transformer, and the overall height of the device is relatively low, which is convenient for indoor transfer or transfer into the room.

[0031] Embodiment 1

[0032] Such as Figures 4 to 5As shown, in this embodiment, the hoisting assembly 300 includes a second lead screw 350. The second lead screw 350 is rotatably installed on the lateral seat rod 120. One end of the second lead screw 350 is threadedly connected with a traction head 340. A limiting groove 121 is formed in the top surface of the lateral seat rod 120 corresponding to the position of the second lead screw 350. The bottom end of the traction head 340 is slidably connected to the inner wall of the limiting groove 121. The other end of the traction rope 150 is fixedly connected to the adjacent traction head 340. The hoisting assembly 300 further includes two second guide wheels 310. The two second guide wheels 310 are respectively rotatably installed on one side wall of the bottom ends of the two vertical frames 140. One end of the top surface of the lateral seat rod 120 is rotatably connected with a third guide wheel 320. The middle position of the top surface of the lateral seat rod 120 is rotatably connected with a fourth guide wheel 330. The other end of one of the two traction ropes 150 on the same side bypasses one second guide wheel 310 and is fixedly connected to the traction head 340, and the other end of the other traction rope 150 bypasses the other second guide wheel 310, the third guide wheel 320 and the fourth guide wheel 330 in sequence and is fixedly connected to the traction head 340. The other end of the second lead screw 350 is fixedly connected with a sleeve 351.

[0033] In this embodiment, for the convenience of clear description, taking the lateral seat rod 120, the hoisting assembly 300, and the two traction ropes 150 on one side as an example, a steel pipe or steel bar is inserted into the sleeve 351 to serve as a lever to rotate the second lead screw 350. When the second lead screw 350 rotates, it drives the traction head 340 to slide along the limiting groove 121. The traction head 340 simultaneously pulls the other ends of the two traction ropes 150, so as to realize the tightening of the traction ropes 150, thereby lifting the transformer. By synchronously retracting and releasing the two traction ropes 150 on the same side through the hoisting assembly 300, the two top corners on one side of the transformer are synchronously lifted, reducing the inclination of the transformer after being lifted. Through the arrangement of the third guide wheel 320 and the fourth guide wheel 330, the other end of one traction rope 150 is guided, facilitating the traction head 340 to synchronously pull the other ends of the two traction ropes 150.

[0034] As Figures 1 to 3 As shown, in this embodiment, universal wheels 170 are installed at both ends of the bottom side of the lateral seat rod 120 and the bottom side of the central seat rod 110. One end of the central seat rod 110 is rotatably installed with a double-axis connection seat 112, and the top end of the double-axis connection seat 112 is rotatably connected with a traction rod 111.

[0035] During specific implementation, the universal wheels 170 rotate along with the moving direction, and the bottom frame assembly 100 is tractionally moved by pulling the traction rod 111.

[0036] Embodiment 2

[0037] On the basis of Embodiment 1, in order to make up for the inclination of the transformer after being lifted caused by the different extension degrees of the two traction ropes 150 on the same side in Embodiment 1.

[0038] As shown Figures 4 to 6 in FIG. 0, in this embodiment, the adjustment assembly 200 includes a first fixing seat 210 and a second fixing seat 220. The first fixing seat 210 and the second fixing seat 220 are both fixedly connected to the adjacent vertical frame 140. A first lead screw 270 is rotatably connected between one ends of the first fixing seat 210 and the second fixing seat 220. One end of the first fixing seat 210 is rotatably connected to a first bracket 230. One end of the first bracket 230 is rotatably sleeved with a wheel shaft 250. A second bracket 240 is arranged above the first bracket 230. The bottom end of the second bracket 240 is rotatably sleeved with the wheel shaft 250. The bottom end of the second bracket 240 is rotatably connected to a threaded sleeve 241. The threaded sleeve 241 is in screw connection with the first lead screw 270. An extrusion wheel 260 is rotatably sleeved on the outer side wall of the wheel shaft 250.

[0039] During specific implementation, manually rotate the first lead screw 270. The first lead screw 270 drives the threaded sleeve 241 to move up and down, so as to drive the extrusion wheel 260 to move away from or close to the first lead screw 270 through the second bracket 240 and the first bracket 230. When the extrusion wheel 260 moves away from the first lead screw 270, it extrudes the middle position of the traction rope 150, so that the part of the traction rope 150 between the second support roller 143 and the second guide wheel 310 is bent, thereby improving the tension of the traction rope 150. In the first embodiment, although the hoisting assembly 300 retracts and releases the two traction ropes 150 on the same side synchronously, after the two traction ropes 150 are used for a period of time or when the pulling forces are inconsistent, the extension degrees of the two traction ropes 150 will be different, resulting in different lifting heights of the two traction ropes 150. However, through the setting of the adjustment assembly 200, the tension of a single traction rope 150 can be adjusted, which is convenient for leveling the lifted transformer.

[0040] As shown Figures 2 to 4 in FIG. 0, in this embodiment, a support module 160 is arranged between the other ends of the two lateral seat rods 120. The support module 160 is used to limit the distance between the two lateral seat rods 120. The support module 160 includes a second double-axis connection seat 162 and a U-shaped clamping seat 163. The bottom end of the second double-axis connection seat 162 is rotatably connected to the top surface of the other end of one lateral seat rod 120. The U-shaped clamping seat 163 is fixedly installed at the other end of the other lateral seat rod 120. The top end of the second double-axis connection seat 162 is rotatably connected to a support rod 164. A threaded groove is opened at one end of the support rod 164. Two oppositely arranged limit seats 161 are screwed to the other end of the support rod 164.

[0041] During specific implementation, after the transformer is lifted, rotate the support rod 164 so that the support rod 164 is stuck in the U-shaped card seat 163, and the two limit seats 161 are located on both sides of the U-shaped card seat 163. Rotate the two limit seats 161 so that the two limit seats 161 clamp the U-shaped card seat 163. Thus, the distance between the two lateral seat rods 120 is restricted by the arrangement of the support rod 164, facilitating stable movement. Moreover, due to the arrangement of the two lateral seat rods 120 and the support rod 164, when the device is in no-load or idle state, the two lateral seat rods 120 can approach each other, making the whole device narrower and facilitating use.

[0042] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above-described exemplary embodiments, and without departing from the spirit or basic characteristics of the present invention, the present invention can be implemented in other specific forms. Therefore, from any perspective, the embodiments should be regarded as exemplary and non-limiting. The scope of the present invention is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be encompassed within the present invention. Any reference signs in the claims should not be regarded as limiting the claims involved.

[0043] In addition, it should be understood that although this specification is described according to embodiments, not every embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
