Description

Technical Field

[0001] This utility model relates to the field of lifting devices, specifically a simple device for lifting ton bags. Background Technology

[0002] A ton bag, also known as a flexible container bag, bulk bag, or space bag, is a medium-sized bulk container and a type of unitized container. When used with a crane or forklift, it enables unitized transport of goods. A search of application CN202123327828.2 discloses a ton bag lifting device, which includes a guide rail, a sliding seat slidably connected inside the guide rail, and telescopic rods fixedly connected to both the front and rear sides of the sliding seat. The bottom ends of the telescopic rods are fixedly connected to the front and rear sides of the top of a lifting frame, respectively. The top of the sliding seat rotates... The device is connected to a reel, with a steel strip fixedly connected to the middle of the reel. The bottom end of the steel strip passes through the hole in the middle of the sliding seat and is fixedly connected to the middle of the top of the hanger. The right end of the reel shaft is fixedly connected to the second drive end of the motor. When the ton bag needs to be unloaded, the third drive motor makes the turntable rotate, which in turn drives the connecting rod to deflect through the second universal joint. Because this action shortens the straight distance between the end of the connecting rod away from the center of the main body and the turntable, the arc hook flips, realizing the purpose of automatically detaching the ton bag hanging ear, that is, achieving the self-unloading effect and improving work efficiency.

[0003] However, the above description still has the following drawbacks in actual use: the device is not convenient for clamping and fixing partially closed ton bags during use, and since the ton bags have a certain weight, it is not convenient to put them directly into the device. Therefore, it is necessary to design a simple device for lifting ton bags with strong practicality. Utility Model Content

[0004] The purpose of this invention is to provide a simple device for lifting ton bags, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a simple device for lifting ton bags, including a base plate, a support frame on one side of the top of the base plate, a fixed frame on the top of the support frame, and sliding grooves on both sides of the inner wall of the fixed frame. The inner walls of the two sliding grooves are connected to a winding assembly through an adjustment component. The winding assembly includes a strong pull rope, and the bottom of the strong pull rope is connected to the ton bag through a clamping component.

[0006] An adjustment assembly includes two first bearings mounted on one side of the inner wall of two slide grooves. The inner walls of the two first bearings are rotatably connected with threaded rods. The other ends of the two threaded rods are fixedly connected to the output shafts of two first motors.

[0027] Please see Figure 3 Adjustment component 2 includes two first bearings 21 installed on one side of the inner wall of two slide grooves 13. The inner walls of the two first bearings 21 are rotatably connected with threaded rods 22. The other ends of the two threaded rods 22 are fixedly connected to the output shafts of two first motors 23. The surfaces of the two threaded rods 22 are provided with sliders 24. The opposite sides of the two sliders 24 are fixedly connected to the two sides of the mounting base 25. The two sides of the mounting base 25 are provided with through grooves 26. The inner walls of the through grooves 26 are provided with winding components 3.

[0028] In practical use: two first motors 23, together with two first bearings 21, drive two threaded rods 22 to rotate. The two threaded rods 22 drive two sliders 24 to move on the inner wall of two slide grooves 13. The two sliders 24 drive the mounting base 25 connected to them to move. The mounting base 25 drives the ton bag clamped and fixed at the bottom to move, so that it enters the interior of the support frame 11, which is convenient for unloading after lifting.

[0029] Please see Figure 4 The clamping assembly 4 includes a connecting block 41 fixedly connected to the bottom of the strong pull rope 31. Both sides of the connecting block 41 are provided with chain locks 42. The other ends of the two chain locks 42 are respectively sleeved on the surface of two protrusions 43. One end of the two protrusions 43 is fixedly connected to one end of two arc-shaped clamping rods 44. The other end of the two protrusions 43 is provided with a limiting ring 45. The middle part of the opposite side of the two arc-shaped clamping rods 44 is sleeved on the surface of the connecting shaft 46.

[0041] In practical use: the control panel 17 is used to control the first motor 23 and the second motor 34, thereby facilitating the clamping and lifting of the partially enclosed ton bag.

[0042] In use, the second motor 34, in conjunction with the second bearing 33, drives the take-up roller 32 to rotate. The take-up roller 32, in conjunction with the strong pull rope 31, drives the connecting block 41 to move. The connecting block 41 drives the two chain locks 42 to move. The two chain locks 42, in conjunction with the two protrusions 43, drive the two arc-shaped clamping rods 44 to move. The two arc-shaped clamping rods 44, in conjunction with the two rotating holes 48, rotate on the surface of the connecting shaft 46 and drive the two clamping plates 47 at the other end to move towards each other until the two clamping plates 47 clamp and fix the partially closed ton bag. Then, the second motor 34, in conjunction with the strong pull rope 31 on the take-up roller 32, lifts the ton bag to complete the required operation. The two first motors 23, in conjunction with the two first bearings 21, drive the two threaded rods 22 to rotate. The two threaded rods 22 drive the two sliders 24 to move on the inner wall of the two slide grooves 13. The two sliders 24 drive the mounting base 25 connected to them to move. The mounting base 25 drives the ton bag clamped and fixed at the bottom to move, so that it enters the interior of the support frame 11, which is convenient for unloading after lifting.
