[0037] In the present invention, the descriptions of directions such as "up", "down", "left", "right", "front", and "back" are as follows: Figure 1 and Figure 2 The directions shown are for reference only and are used to explain the Figure 1 and Figure 2 The relative position relationship between the components in the shown posture. If the specific posture changes, the directional indication will also change accordingly.

[0038] The invention provides a traction type power device.

[0039] like Figures 1 to 8As shown, the traction power device of this embodiment includes a base 10, an adjustment mechanism 20 and a power mechanism 30, wherein the adjustment mechanism 20 includes a support plate 21, a movable plate 22 and a drive assembly 23, the support plate 21 is installed on the base 10 through a frame 11, the movable plate 22 is hinged to one end of the support plate 21, and the drive assembly 23 is used to drive the movable plate 22 to rotate relative to the support plate 21, so that the movable plate 22 is unfolded to extend the support plate 21 or folded on the support plate 21; the power mechanism 30 includes a winch 31 and a guide assembly 32, the winch 31 is installed on the base 10 and is located below the support plate 21, and the traction rope 311 of the winch 31 is guided by the guide assembly 32 and extends from the end of the support plate 21 where the movable plate 22 is located.

[0040] During use of the traction power device of this embodiment, the support plate 21 is at the same height as the truck compartment, and the driving assembly 23 drives the movable plate 22 to rotate relative to the support plate 21, so that the movable plate 22 is unfolded. After the movable plate 22 is unfolded, it can be extended into the truck compartment, thereby extending the support plate 21, so that the support plate 21 is connected to the truck compartment through the movable plate 22, which is convenient for the subsequent loading and unloading process. After the movable plate 22 is extended into the truck compartment, the traction rope 311 of the winch 31 is connected to the material to be unloaded in the compartment, and the power mechanism 30 is started. The traction rope 311 of the winch 31 pulls the material to move outside the compartment and moves to the support plate 21, so as to pull the material in the compartment to the outside of the compartment, and complete the unloading process. Similarly, when loading is required, the material to be loaded is placed on the support plate 21. After the movable plate 22 is extended into the truck compartment, the traction rope 311 of the winch 31 is connected to the material to be loaded outside the compartment, and the power mechanism 30 is started. The traction rope 311 of the winch 31 then pulls the material in the opposite direction toward the compartment and moves it into the compartment, so as to pull the material outside the compartment into the compartment, thereby completing the loading process.

[0041] It can be understood that after the loading and unloading of materials is completed, the traction rope 311 of the winch 31 is disconnected from the materials, the truck moves away, the movable plate 22 is disconnected from the truck compartment, and the drive assembly 23 drives the movable plate 22 to rotate relative to the support plate 21 so that the movable plate 22 is folded on the support plate 21 so that the movable plate 22 returns to its original position.

[0042] The traction power device of this embodiment can quickly realize the material loading and unloading process by setting the adjustment mechanism 20 and the power mechanism 30, and the loading and unloading efficiency is high. In addition, the traction power device integrates the supporting function and the traction function, has a high degree of functional integration, a wide range of uses, and a large application range.

[0043] Specifically, the winch 31 includes a driving member 312 and a drum 313, the traction rope 311 is wound around the drum 313, and the driving member 312 is used to drive the drum 313 to rotate; the guide assembly 32 includes a first guide wheel 321 and a second guide wheel 322, the first guide wheel 321 is installed on the base 10 and is arranged away from the winch 31, and the rotating shaft of the drum 313 and the rotating shaft of the first guide wheel 321 are both arranged along the X direction, the second guide wheel 322 is installed at the bottom of the support plate 21 and is located between the winch 31 and the first guide wheel 321, and the rotating shaft of the second guide wheel 322 is arranged along the Z direction, and the free end of the traction rope 311 is successively wound around the first guide wheel 321 and the second guide wheel 322 and then extends from the end of the support plate 21 where the movable plate 22 is located.

[0044] The driving member 312 of this embodiment can be a motor in the prior art, and the motor drives the reel 313 to rotate, and the reel 313 pulls the material through the traction rope 311. Figure 1 and Figure 2 The front-to-back direction shown in the figure is the Y direction. Figure 2 The left and right directions shown in the figure are the Z direction. Figure 1 The movable plate 22 is hinged to the front end of the support plate 21, that is, the end of the support plate 21 where the movable plate 22 is located is the front end.

[0045] In order to improve the smoothness of winding of the drum 313, the guide assembly 32 of this embodiment includes a first guide wheel 321 and a second guide wheel 322, wherein the first guide wheel 321 is arranged away from the winch 31, the rotating shaft of the drum 313 and the rotating shaft of the first guide wheel 321 are arranged in the front-to-back direction, and the second guide wheel 322 is located between the winch 31 and the first guide wheel 321, and the rotating shaft of the second guide wheel 322 is arranged in the up-down direction. The traction rope 311 is wound around the drum 313, and the free end of the traction rope 311 can be wound around the first guide wheel 321 and the second guide wheel 322 in sequence and then extend from the front end of the support plate 21 to facilitate the connection of materials in the carriage.

[0046] It should be noted that the first guide wheel 321 and the second guide wheel 322 both guide the traction rope 311, and the first guide wheel 321 is arranged away from the winch 31, so that the swing angle of the traction rope 311 from the drum 313 to the first guide wheel 321 is small, which is conducive to the traction rope 311 being neatly wound on the drum 313 without the phenomenon of random winding and winding. The wire arrangement device is omitted, and the structure of the winch 31 is simplified. The design is ingenious and reasonable. Figure 2As shown, the first guide wheel 321 of this embodiment is installed on the base 10 and is arranged near the left end of the support plate 21, while the winch 31 is arranged near the right end of the support plate 21, and the second guide wheel 322 is located between the winch 31 and the first guide wheel 321, so that the space under the support plate 21 can be fully utilized, the structure is compact, and the volume occupied is small.

[0047] Furthermore, the guide assembly 32 also includes a third guide wheel 323, which is mounted on the support plate 21 and extends from the top of the support plate 21, and the third guide wheel 323 is arranged close to the movable plate 22, and the rotating shaft of the third guide wheel 323 is arranged along the Y direction, and the first guide wheel 321, the second guide wheel 322 and the third guide wheel 323 form a first guide path, so that the free end of the traction rope 311 can be sequentially wound around the first guide wheel 321, the second guide wheel 322 and the third guide wheel 323 and then extend from the end of the support plate 21 where the movable plate 22 is located.

[0048] In this embodiment, the third guide wheel 323 is arranged near the front end of the support plate 21, and the rotating shaft of the third guide wheel 323 is arranged along the Y direction, which guides the traction rope 311. In this embodiment, by setting the first guide path, the free end of the traction rope 311 is firstly wound around the first guide wheel 321, specifically, from the bottom of the first guide wheel 321 to the top of the first guide wheel 321, to achieve a first reversal, then, it extends from the top of the first guide wheel 321 and is wound from the rear of the second guide wheel 322 to the front of the second guide wheel 322, to achieve a second reversal, and finally, it extends from the front of the second guide wheel 322 and extends from the top of the third guide wheel 323 to the support plate 21 and connects with the material in the carriage, to achieve the forward and backward pulling of the material, and complete the rapid loading and unloading process.

[0049] In this embodiment, the first guide wheel 321, the second guide wheel 322 and the third guide wheel 323 form a first guide path to guide the wire rope of the winch 31 to run along the first guide path, which is simple and convenient and improves the smoothness of material traction.

[0050] Furthermore, the guide assembly 32 also includes a fourth guide wheel 324 and a fifth guide wheel 325. The fourth guide wheel 324 is installed at the bottom of the support plate 21 and is arranged on both sides of the reel 313 with the second guide wheel 322. The fifth guide wheel 325 is installed on the support plate 21 and extends from the top of the support plate 21. The fifth guide wheel 325 is arranged close to the movable plate 22. The rotating shaft of the fourth guide wheel 324 is arranged along the Z direction, and the rotating shaft of the fifth guide wheel 325 is arranged along the Y direction. The first guide wheel 321, the fourth guide wheel 324 and the fifth guide wheel 325 form a second guide path, so that the free end of the traction rope 311 can also be successively wound around the first guide wheel 321, the fourth guide wheel 324 and the fifth guide wheel 325 and then extend from the end of the support plate 21 where the movable plate 22 is located.

In this embodiment, by setting the second guide path, the free end of the traction rope 311 is firstly wound around the first guide wheel 321, specifically, from the bottom of the first guide wheel 321 to the top of the first guide wheel 321, so as to realize a first reversal, then, it extends from the top of the first guide wheel 321 and is wound from the rear of the fourth guide wheel 324 to the front of the fourth guide wheel 324, so as to realize a second reversal, and finally, it extends from the front of the fourth guide wheel 324 and extends from the top of the fifth guide wheel 325 to the support plate 21 to connect with the materials in the carriage, so as to realize the forward and backward pulling of the materials, and complete the rapid loading and unloading process.

[0052] It should be noted that the routing of the traction rope 311 of the winch 31 can choose either the first guide path or the second guide path, that is, the traction rope 311 of the winch 31 can choose the first guide path to achieve the forward and backward pulling of the material, and can also choose the second guide path to achieve the forward and backward pulling of the material, so that the traction power device can select the routing path of the traction rope 311 according to actual conditions, which is flexible and convenient.

The structural design is reasonable, which is conducive to the loading and unloading of materials.

[0054] In this embodiment, a first guide roller 326 for guiding the traction rope 311 is arranged between the first guide wheel 321 and the second guide wheel 322, and the rotating axis of the first guide roller 326 is arranged along the Z direction; a second guide roller 327 for guiding the traction rope 311 is arranged between the second guide wheel 322 and the third guide wheel 323, and the rotating axis of the second guide roller 327 is arranged along the Y direction; a third guide roller 328 for guiding the traction rope 311 is arranged between the fourth guide wheel 324 and the fifth guide wheel 325, and the rotating axis of the third guide roller 328 is arranged along the Y direction.

[0055] In this embodiment, the wall of the reel 313 is provided with a plurality of wiring grooves 314 arranged in sequence along the X direction, and / or the distance between the first guide wheel 321 and the reel 313 is 1.5m to 2m. Figure 5 As shown, the wall of the drum 313 is provided with a plurality of wiring grooves 314 arranged in sequence along the front-to-back direction. The wiring grooves 314 are annular and surround the outer periphery of the drum 313. The shape of the wiring grooves 314 matches the shape of the traction rope 311, which is conducive to the traction rope 311 being neatly wound around the drum 313 without the phenomenon of random winding and twisting. In addition, in order to minimize the swing angle of the traction rope 311 from the drum 313 to the first guide wheel 321, the distance between the first guide wheel 321 and the drum 313 can be set to 1.5m to 2m. The traction rope 311 of this embodiment can be a steel wire rope with good strength.

[0056] like Figure 4 and Figure 5As shown, the winch 31 of this embodiment includes two mounting plates 315, and the two mounting plates 315 are installed on the base 10 at intervals along the X direction, and the two ends of the drum 313 are rotatably installed on the two mounting plates 315 respectively; the winch 31 also includes a first limiting assembly and a second limiting assembly, the first limiting assembly includes a first limiting rod 316 and a first spring 317, the first limiting rod 316 is arranged along the X direction and is located below the drum 313, the first spring 317 is arranged along the Z direction, and one end of the first spring 317 is connected to the first limiting rod 316, and the other end of the first spring 317 is connected to the mounting plate 315; the second limiting assembly includes a second limiting rod 318 and a second spring 319, the second limiting rod 318 is arranged along the X direction and is located on one side of the drum 313, the second spring 319 is arranged along the Y direction, and one end of the second spring 319 is connected to the second limiting rod 318, and the other end of the second spring 319 is connected to the mounting plate 315.

[0057] like Figure 4 and Figure 5 As shown, the first limiting rod 316 is located below the reel 313, and the reel 313 is limited in the Z direction by the elastic action of the first spring 317, so that the traction rope 311 on the reel 313 can stably run in the wiring groove 314. Further, the second limiting rod 318 is located on the left side of the reel 313, and the reel 313 is limited in the Y direction by the elastic action of the second spring 319, so that the traction rope 311 on the reel 313 can stably run in the wiring groove 314. In this embodiment, by providing the first limiting assembly and the second limiting assembly, the reel 313 can be limited in the Z direction and the Y direction respectively, so as to improve the reliability of the traction rope 311 being able to stably run in the wiring groove 314 and avoid the phenomenon of random winding and random rolling. In addition, due to the action of the first limiting assembly and the second limiting assembly, the pressure on the reel 313 can be increased, and the inertia of the reel 313 caused by the pulling of the traction rope 311 can be eliminated. In one embodiment, a sensing switch 33 may be provided on the first limiting rod 316 , and the sensing switch 33 may sense the position of the traction rope 311 to prevent the traction rope 311 from being completely pulled out of the reel 313 .

[0058] In this embodiment, a position sensor 40 is also installed at the bottom of the support plate 21. The position sensor 40 is arranged close to the movable plate 22 and is used to sense the position of the movable plate 22. It can be understood that the traction power device in this embodiment can be electrically connected to a control system. The position sensor 40 can sense the position of the movable plate 22. After loading and unloading materials, the drive component 23 drives the movable plate 22 to fold on the support plate 21. The position sensor 40 sends the sensed position information of the movable plate 22 to the control system. The control system receives the position information and determines whether the movable plate 22 is folded into place based on the position information. When it is in place, the operator is prompted to move the truck that has finished loading and unloading materials away, thereby avoiding safety hazards caused by moving the truck away before the materials are fully loaded and unloaded. The safety is high. Figure 1 , Figure 2 , Figure 7 and Figure 8 As shown, when the movable plate 22 is unfolded, it can be located on the same horizontal plane as the support plate 21. When the movable plate 22 is folded, it can be vertically arranged with the support plate 21, which is a reasonable design.

[0059] In this embodiment, the driving component 23 is located below the support plate 21. The driving component 23 includes a connecting rod mechanism 231, an airbag 232 and an inflation and deflation component 233. The connecting rod mechanism 231 connects the support plate 21 and the movable plate 22.

[0060] like Figure 1 As shown, the driving assembly 23 is located below the support plate 21, with a compact structure to avoid space waste. The inflating and deflation member 233 can adopt a fan in the prior art, and the fan can inflate and deflate the airbag 232. Specifically, the connecting rod mechanism 231 of this embodiment includes a first push rod 2311, a second push rod 2312 and a connecting plate 2313, wherein the first end of the first push rod 2311 is hinged to the frame 11, the position of the first push rod 2311 near its second end is hinged to the mounting ear 211 at the bottom of the support plate 21, one end of the connecting plate 2313 is hinged to the first push rod 2311, the other end of the connecting plate 2313 is hinged to the first end of the second push rod 2312, and the second end of the second push rod 2312 is hinged to the movable plate 22; a locking rod 2314 is provided on the connecting plate 2313, and a locking groove 2315 is provided on the first push rod 2311 near the locking rod 2314.

[0061] When the traction power device is in use, the inflatable and deflation member 233 inflates the airbag 232, the airbag 232 expands and drives the support plate 21 to rise, so that the locking rod 2314 is inserted into the locking groove 2315 to achieve locking. Then, the inflatable and deflation member 233 deflates the airbag 232, the airbag 232 contracts and drives the support plate 21 to descend.

The second push rod 2312 can push the movable plate 22 forward during the descent of the support plate 21, so that the movable plate 22 rotates upward relative to the support plate 21, so as to realize the deployment of the movable plate 22. Figure 7 After use, the inflatable and deflation member 233 inflates the airbag 232 for a second time, and the airbag 232 expands and drives the support plate 21 to rise for a second time, so that the locking rod 2314 is separated from the locking groove 2315 to achieve unlocking. Then, the inflatable and deflation member 233 deflates the airbag 232 for a second time, and the airbag 232 shrinks and drives the support plate 21 to descend for a second time. The connecting rod mechanism 231 and the support plate 21 act in conjunction, and the second push rod 2312 can pull the movable plate 22 backwards during the second descent of the support plate 21, so that the movable plate 22 rotates downward relative to the support plate 21, and the movable plate 22 is folded, as shown. Figure 8 As shown, the structure is reasonably designed and easy to operate.
