AI Technical Summary
In the mechanical equipment industry, due to the compact placement of spare parts and space limitations when objects are transported, it is unrealistic to use forklifts or lifting equipment to lift, and the wire rope cannot be tied, resulting in safety risks and inefficiency.
A simple lifting device is designed, including columns, sprockets, bases, locking components, front shovels and transmission chains. The handle is reciprocated and pressed, and the transmission function of the sprockets and transmission chains are used to insert the front shovels into the lower part of the object, gradually lifting and fixing the object, for easy lifting.
The device improves labor efficiency, saves working time, reduces safety risks, solves safety technical problems when objects are transported backwards, and is suitable for object improvement in the mechanical equipment industry, with low production costs and wide application.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of lifting equipment, in particular to a simple lifting device. Background Art
[0002] In the machinery equipment industry, there are often a lot of object handling operations. In the early stage, due to the different arrival times of spare parts and regional restrictions, the placement of objects can only meet the utilization rate of the site to a certain extent. In the later stage, when some of the spare parts need to be used, and the placement of the surrounding spare parts is relatively compact, it is often unrealistic to use a forklift to handle them from the outside to the inside in turn. When directly using a lifting equipment for hoisting, because the gap between it and the ground is small or there is no gap, the steel wire rope or sling cannot be tied at this time. Content of the Utility Model
[0003] In view of the above technical problems, the utility model provides a simple lifting device.
[0004] In order to achieve the above purpose, the technical solution of the utility model is specifically as follows:
[0005] A simple lifting device, comprising:
[0006] A column;
[0007] A sprocket, vertically arranged at the top of the column and rotatable;
[0008] A base, slidably arranged on the column up and down, with a locking component arranged at one end and a front shovel arranged at the other end. Among them, the locking component is used for fixing after the base slides in place;
[0009] A transmission chain, with one end assembled on the sprocket and the other end connected to the base.
[0010] A handle is arranged on the rotating shaft of the sprocket.
[0011] The beneficial effects of the utility model are as follows:
[0012] 1. The utility model only needs to be vertically placed beside the spare parts to be handled, and the front shovel of the lifting device is inserted or knocked into 20 mm below the spare parts. At this time, the handle is reciprocally pressed, and the front shovel rises. When it rises 50 - 60 mm, a supporting object is quickly inserted below, and then the front shovel falls back. When it completely falls back below the spare parts, the front shovel is reinserted reliably below the spare parts to be handled in its entirety. The handle is reciprocally pressed to lift the spare parts, the locking bolt is tightened, a supporting object is placed, and the above steps are repeated to lift the four corners of the spare parts in turn and then insert the steel wire rope, and then it is lifted away by a crane. Using this lifting device improves labor efficiency, saves operation time, reduces safety risks, and fundamentally solves the safety technical problems of such operations.
[0013] 2. Often when lifting objects on site, due to limited space or no gap at the bottom, the wire rope cannot be directly inserted. The current method usually involves using a crowbar to insert it into the lower part and pressing hard, which is likely to cause personnel to lose their balance. With the present utility model, simply insert the front shovel into the protruding part of the object, reciprocally press the handle, and use the lever principle to lift the object to create a gap, then repeat this method 1 - 3 times to lift the object off the ground. Of course, this design includes the lifting during the reverse transportation of the object, but is limited to this. When fine adjustment is required in other situations where the press cannot be placed, this design can also be used, and there is no angle limit.
[0014] 3. Compared with the prior art, the present utility model has a simple structure, improves labor efficiency, reduces safety risks, is easy to operate, can be learned immediately, has a wide range of applications, can be used for lifting objects in the mechanical equipment industry, has a low production cost, and can be mass-produced. BRIEF DESCRIPTION OF THE DRAWINGS
[0015] The following further describes in detail the specific embodiments of the present utility model in conjunction with the drawings.
[0016] Figure 1 This is the schematic diagram of the present utility model. SPECIFIC EMBODIMENTS
[0017] To make the purpose, technical solutions and advantages of the present utility model clearer, the following further details the present utility model in conjunction with the specific embodiments and with reference to the drawings. It should be understood that these descriptions are exemplary and not intended to limit the scope of the present utility model. In addition, in the following description, the descriptions of well-known structures and technologies are omitted to avoid unnecessarily confusing the concepts of the present utility model.
[0018] As Figure 1 shown, a simple lifting device includes: a column 7; a sprocket 6 rotatably and vertically arranged at the top of the column 7; a base 5 slidably arranged on the column 7, with a locking component 4 provided at one end and a front shovel 3 provided at the other end, wherein the locking component 4 is used for fixing the base 5 after it slides into place; a transmission chain 2, one end of which is assembled on the sprocket 6 and the other end is connected to the base 5, and a handle 1 is provided on the rotating shaft of the sprocket 6.
[0019] The locking component 4 is a locking bolt. A threaded hole is horizontally provided on the side wall of one end of the base 5, and the locking bolt is fitted and installed in the threaded hole. When the locking bolt is rotated, the head of the locking bolt will gradually approach the side wall of the column 7. When it abuts against the side wall of the column 7, the base 5 and the column 7 are fixed to each other.
[0020] When the utility model is in use, the front shovel 3 can be inserted or knocked into the spare part by 20 mm. At this time, the handle 1 is reciprocally pressed, and the sprocket 6 rotates accordingly, driving the transmission chain 2 to pull the base 5 upward. The front shovel 3 rises accordingly. When it rises by 50 - 60 mm, a cushioning object is quickly inserted under the equipment, then the front shovel 3 is lowered, completely lowered under the spare part. Then the front shovel 3 is re-inserted completely and reliably under the spare part to be transported. The handle 1 is reciprocally pressed to lift the spare part, the locking bolt is tightened, a cushioning object is placed, and the above steps are repeated to lift the four corners of the spare part in turn, then a steel wire rope is inserted, and the spare part is lifted away by a crane.
[0021] The above are only the preferred embodiments of the present utility model, and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
