Description
Technical Field
[0001] The utility model relates to the field of building construction hoisting, and more specifically, to a building construction hoisting device. Background Art
[0002] Construction includes main structure construction, roof construction, decoration construction, etc. The place where construction is carried out is called "construction site" or "construction site", also known as construction site. Usually, materials need to be hoisted at the construction site. Hoisting refers to the installation and positioning of equipment by cranes or lifting mechanisms. During the inspection or maintenance process, various hoisting machines are used to lift equipment, workpieces, tools, materials, etc. to change their positions.
[0003] Based on the above, the inventors have found that most of the existing hoists tie ropes to the outside of materials, such as pipes, etc., and then use hooks to lift them. However, the stability of rope-bound materials is low, which may cause the materials to tilt and fall during the lifting process. At the same time, rope-binding materials is time-consuming and labor-intensive. Therefore, in view of this, the existing structure is studied and improved to provide a construction hoist in order to achieve a more practical purpose. Utility Model Content

[0006] A construction hoist comprises a hoist body, a sling end of the hoist body is fixedly installed with a clamping box, a servo motor is fixedly installed on one side of the clamping box, the output end of the servo motor is connected with a screw rod through a coupling transmission, one end of the screw rod extends to the interior of the clamping box through a through slot, and one end of the screw rod is connected to one side of the inner wall of the clamping box through a bearing, the outer wall of the screw rod is connected with a pair of moving blocks through threads, the bottom ends of the pair of moving blocks are fixedly installed with a prismatic connecting rod, one end of the two prismatic connecting rods extend to the outside of the bottom end of the clamping box through the through slot, one end of the two prismatic connecting rods are fixedly installed with a clamping plate, one end of the clamping plate is provided with an extension plate, the outer walls of the two groups of the clamping plates and the extension plates are evenly provided with through holes, a limit spring is fixedly installed inside the through hole, and a limit column is fixedly installed at one end of the limit spring.
[0007] Furthermore, the thread of the outer wall of the screw rod is divided into two sections, and the threads of the two sections are in opposite directions.
[0008] Furthermore, one end of the clamping plate is connected to one end of the extension plate via a rotating shaft, and the positions of the clamping plate and the extension plate are symmetrical to each other.
[0009] Furthermore, one side of the clamping plate and the expansion plate are fixedly installed with limiting holes, and the positions of the two limiting holes are symmetrical to each other. A limiting rod is inserted and installed inside the two limiting holes, and one end of the limiting rod is "n" shaped.
[0010] Furthermore, a pair of card slots are provided at the top of the inner wall of the clamping box, card blocks are mounted inside the pair of card slots, and one end of the two card blocks is fixedly connected to the top of the two moving blocks respectively.

[0012] Compared with the prior art, the advantages of the present invention are:
[0013] (1) This solution, by setting up a servo motor, a screw rod, a limit spring and a limit column, after the device is put into use, the servo motor drives the screw rod to rotate, so that the two moving blocks on the outside of the screw rod approach each other, thereby driving the two clamping plates to approach each other and clamp the material. At the same time, when the material is clamped, the limit spring will be squeezed and drive the limit column to shrink, so that the material is in full contact with one end of the limit column, and the unshrinking limit column is used to engage and limit the edge of the material, so that the material can be effectively clamped, and then the material is lifted by the hoisting device body. The device can effectively improve the stability of the material during lifting and the adaptability of the material during clamping.
[0014] (2) In this solution, by setting a limit hole and a limit rod, when the clamping plate needs to be extended, the clamping plate and the extension plate are folded, and the limit rod is pulled out of the limit hole on one side of the clamping plate. At the same time, one end of the limit rod in an N shape is separated from the limit hole on one side of the extension plate. Then, the extension plate is folded to the bottom of the clamping plate, and then the limit rod is inserted into the limit holes on one side of the clamping plate and the extension plate. The position of the clamping plate and the extension plate can be fixed. This structure can effectively improve the adaptability of the clamping plate and the extension plate when clamping materials of different heights and sizes. BRIEF DESCRIPTION OF THE DRAWINGS
