Description

Technical Field

[0001] This utility model relates to the field of steel plate hoisting technology, specifically a multi-functional steel plate hoisting tool. Background Technology

[0002] Steel plate lifting tools are tools used for lifting steel plate items. Currently, there are usually two methods for lifting steel plates: one is to lift them with a hook, and the other is to lift them with an electromagnetic lifting tool.

[0003] Because electromagnetic magnets are complex and expensive, they are not widely used; hooks are more commonly used for lifting. During lifting, the lifting device is first placed on a steel plate, and the hooks at the four corners are attached to the edges of the plate. When the crane lifts the plate, the pressure pipes above press it down, and the plate's own weight locks it in place with the hooks, ensuring safe transport.

[0004] However, because the spacing between the lifting devices is not adjustable, these devices can only transport steel plates of a fixed size, which not only makes the devices less versatile but also increases production costs. Utility Model Content

[0005] The purpose of this utility model is to provide a multifunctional steel plate lifting tool to solve the problem that the spacing between lifting tools in the prior art is not adjustable, resulting in poor versatility of the lifting tool and increased production costs.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a multifunctional steel plate lifting device, comprising a rectangular connecting frame and a clamping mechanism. The connecting frame comprises four hollow tubes, with support rods slidably sleeved at the left and right ends of the four hollow tubes respectively. Adjacent support rods are fixedly connected to each other, and a positioning mechanism is provided between the support rods and the hollow tubes. The clamping mechanism comprises four connecting ropes, which are respectively installed at the four corners of the connecting frame. A fixing block is installed at the end of each connecting rope, and a fixing clamping mechanism is installed on the fixing block.

[0007] As a preferred technical solution of this utility model: the fixing clamping mechanism includes a cylinder, the cylinder is installed at the bottom of the fixing block, the cylinder body is fitted with a device plate, two clamping plates are hinged on the surface of the device plate, the two clamping plates are symmetrically arranged along the central axis of the device plate, and the piston rod of the cylinder is connected to the two clamping plates by a pull rod.

[0008] As a preferred technical solution of this utility model: the positioning mechanism includes a limiting rod, the left and right ends of the hollow tube are respectively provided with first through holes, and the support rod is provided with a plurality of second through holes at equal intervals. The limiting rod is used in conjunction with the first through holes and the second through holes.

[0009] As a preferred technical solution of this utility model: a lifting ring is fixedly installed at the top end of the hollow tube.

[0010] The beneficial effects of this utility model by adopting the above technical solution are as follows: This utility model has a simple structure and ingenious design. By adjusting the distance between the support rod and the hollow tube, the fixing clamp mechanism can be placed in the optimal hoisting position for steel plates of different sizes. At the same time, the cylinder and the pull rod are used to achieve the clamping and fixing effect of the two clamping plates on the steel plate, which is convenient, fast and stable.
