The utility model simultaneously realizes the adjustable length of the main body part and the reduction of the activity radius of the screwdriver, reducing the manpower, material resources and time required for disassembly and assembly. However, in real life, hoisting in narrow spaces is always a relatively difficult situation. Due to space limitations, conventional cranes are not easily accessible to narrow tunnels, so when hoisting items, it is often necessary for workers to lift them through a pulley block, and it is difficult to lift heavy items.

[0004] Therefore, we provide a hoisting tool suitable for narrow spaces to solve the above problems. Content of the Utility Model

[0005] The purpose of the utility model is to provide a hoisting tool suitable for narrow spaces to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A hoisting tool suitable for narrow spaces, including a support frame and a narrow space hoisting mechanism, the narrow space hoisting mechanism is installed on the outer side of the support frame;

[0007] The narrow - space hoisting mechanism includes a wall - supporting component and a roof - mounting component. A wall - supporting component is arranged on the left side of the support frame, and a roof - mounting component is arranged on the right side of the support frame.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0015] 1. Through the setting of the narrow - space hoisting mechanism, when one side needs to be fixed on the wall, the distance between the two side walls can be adjusted through the wall hydraulic pumps, so that the support frame can be firmly fixed in the middle of the wall. In this way, sufficient support can be provided in the roadway for hoisting operations. After the wall hydraulic pumps provide support, due to the relatively long structure of the wall clamping plates themselves, better support effects can be provided, and the friction force can be increased by increasing the contact area to ensure the stability during operation.

[0016] 2. Through the setting of the hoisting mechanism for narrow spaces, when the other side is on the roof, just insert the roof width adjustment pump into the roof support rod, extend it outward according to the width from the roof, until the right angle formed by the wall eaves card plate in the installation card slot engages with the eaves. This can provide support and also cooperate with the wall hydraulic pump and the wall card plate to provide better support, avoiding the problem of being unable to fix due to different forces on both sides. When the roof heights on both sides of the roadway are not much different, it is possible to insert the roof width adjustment pump into both the wall support rods and the roof support rods around the support frame, and insert the height adjustment hydraulic pump rod into the installation card slot. This can adjust the height difference between the roofs on both sides, maintain the horizontal height of the support frame, and better carry out the hoisting operation.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] Embodiment 1

[0024] Please refer to Figures 1-4 as shown, the present utility model provides a technical solution: a hoisting tool suitable for narrow spaces, including a support frame 1 and a hoisting mechanism 2 for narrow spaces. The hoisting mechanism 2 for narrow spaces is installed on the outer side of the support frame 1;

[0025] The hoisting mechanism 2 for narrow spaces includes a wall support assembly 21 and a roof mounting assembly 22. The wall support assembly 21 is arranged on the left side of the support frame 1, and the roof mounting assembly 22 is arranged on the right side of the support frame 1.

[0026] Furthermore, the wall support assembly 21 includes wall support rods 211, wall hydraulic pumps 212 and wall clamping plates 213. The wall support rods 211 are welded to the left side of the support frame 1. The wall hydraulic pumps 212 are connected to the inner sides of the wall support rods 211 through clamping slots. Wall clamping plates 213 are arranged at the ends of the wall hydraulic pumps 212. When it is necessary to fix on one side of the wall, the distance between the two sides of the wall can be adjusted by the wall hydraulic pumps 212, so that the support frame 1 can be firmly fixed in the middle of the wall, which can provide sufficient support in the roadway for hoisting operations.

[0027] Furthermore, the wall clamping plate 213 is welded to the wall hydraulic pump 212. The wall clamping plate 213 is in a semi-C shape. After the wall hydraulic pump 212 supports, due to its relatively long structure, the wall clamping plate 213 can provide a better support effect, improve the friction force by increasing the contact area, and ensure the stability during operation.

[0028] Furthermore, the roof mounting assembly 22 includes roof support rods 221, roof width adjustment pumps 222, mounting slots 223, eaves clamping plates 224 and height adjustment hydraulic pump rods 225. The roof support rods 221 are welded to the right side of the support frame 1. The roof width adjustment pumps 222 are connected to the inner sides of the roof support rods 221 through clamping slots. Mounting slots 223 are welded to the ends of the roof width adjustment pumps 222. The eaves clamping plate 224 is installed inside the front mounting slot 223, and the height adjustment hydraulic pump rod 225 is installed inside the rear mounting slot 223. When the other side is on the roof, just insert the roof width adjustment pump 222 into the roof support rod 221 and extend it out according to the width from the roof until the right angle formed by the eaves clamping plate 224 in the mounting slot 223 is engaged with the eaves. This can provide support and cooperate with the wall hydraulic pump 212 and the wall clamping plate 213 to provide better support, avoiding the problem of being unable to fix due to different forces on both sides.

[0029] Furthermore, the height adjustment hydraulic pump rod 225 is connected to the mounting slot 223 through a clamping slot and is closely fitted with the mounting slot 223. When the roof heights on both sides of the roadway are not much different, the roof width adjustment pumps 222 can be inserted into both the wall support rods 211 and the roof support rods 221 around the support frame 1, and the height adjustment hydraulic pump rods 225 can be inserted into the mounting slots 223. In this way, the height difference between the two sides of the roof can be adjusted to keep the horizontal height of the support frame 1 for better hoisting operations.

[0030] Embodiment 2

[0031] Please refer to Figure 1 and Figure 2 As shown, compared with Embodiment 1, as another implementation manner of the present utility model, a hoisting structure 3 is installed inside the support frame 1. The hoisting structure 3 includes a slide rail rod 31, a slider 32, a towing rope 33 and a winch-type hoist 34. The slide rail rods 31 are welded inside both sides of the support frame 1. A slider 32 is arranged on the outer side of the slide rail rod 31. A towing rope 33 is installed at the top of the slider 32, and a winch-type hoist 34 is installed on the lower side of the slider 32. When in use, as the width of the goods and the installation or unloading position change, the slider 32 on the winch-type hoist 34 can be adjusted along the slide rail rod 31, so as to avoid the problem that it is not easy to touch the goods during unloading due to the relatively wide roadway width.

[0032] Further, the towing rope 33 and the slider 32 are adhesively connected, and the towing rope 33 and the slider 32 are symmetrically arranged on the left and right sides. When unloading, if the unloading position is not fixed, only the people on the left and right sides need to pull the towing rope 33 according to the unloading position to horizontally move the slider 32 along the slide rail rod 31, so that there can be a better operating space.

[0033] Working principle: Move a hoisting tool applicable to narrow spaces to the working position. When in use, in the first step, according to the heights of the roofs of the houses on both sides of the roadway, when the height difference of the roofs is large, insert the wall support rods 211 and the roof support rods 221 around the support frame 1 into the wall hydraulic pump 212, and use the friction of the wall clamping plate 213 for fixation. When one side of the roof can be utilized, replace one side of the roof support rod 221 with the roof width adjustment pump 222 inserted, and snap the wall eaves clamping plate 224 into the installation slot 223, and at the same time snap the wall eaves clamping plate 224 to the side position of the eaves. If the heights of the roofs on both sides are small but there is a certain height difference, select to insert the wall support rods 211 and the roof support rods 221 around the support frame 1 into the roof width adjustment pump 222, and at the same time insert the height control hydraulic pump rod 225 into the installation slot 223, and then adjust according to the height difference through the height control hydraulic pump rod 225 to keep the support frame 1 balanced. During this period, the wall hydraulic pump 212, the roof width adjustment pump 222 and the height control hydraulic pump rod 225 are adjusted according to the actual situation. In the second step, according to the position where the winch-type hoist 34 needs to be used, the staff pulls the slider 32 along the slide rail rod 31 through the towing rope 33 to meet the convenience of the unloading position of the hoisted item, thus completing the use process of a hoisting tool applicable to narrow spaces.

[0034] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model.
