Description

Technical Field

[0001] The utility model belongs to the technical field of building hoisting, in particular to a hoisting device for building construction. Background Art

[0002] During construction, a hook is needed to connect the target. The hook is the most common type of lifting device in lifting machinery. The hook is often suspended on the wire rope of the lifting mechanism with the help of components such as a pulley block.

[0003] When a conventional hook is connected to a rope, the rope can be directly inserted. When the rope is removed, the buckle needs to be pressed to open the space. When the rope occupies a large space, a certain obstruction is formed between the buckle of the hook and the rope, making it difficult to remove the rope, resulting in the problem that it is more troublesome for conventional hooks to remove relatively thick ropes.

[0004] For this reason, we propose a kind of building construction lifting device to solve the above-mentioned problem. Utility Model Content

[0005] The utility model aims to solve the problem that it is troublesome to remove a relatively thick rope from a conventional hook, and proposes a hoisting device for construction.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A hoisting device for construction includes a hook, a stopper rod fixedly connected to the upper portion of the hook, a spring fixedly connected between the hook and the stopper rod, a sliding bolt movably blocked at the lower portion of the stopper rod, the sliding bolt slidingly extending through the hook, and a tension spring fixedly connected between the hook and the sliding bolt. A rope is pressed from the stopper rod toward the hook, causing the stopper rod to overcome the elastic force of the spring and allow the rope to enter the hook. After the rope enters the gap between the hook and the stopper rod, the elastic force of the spring drives the stopper rod upward to return to its original position, and the sliding bolt is pulled outward, causing the sliding bolt to move outward against the tension spring, thereby retracting the sliding bolt into the hook. The rope is then pulled outward, causing the stopper rod to clear the rope, thereby facilitating rope removal.

[0008] Preferably, the hook comprises a docking ring and a hook body, wherein the lower end of the docking ring is fixedly connected to the upper end of the hook body. The docking ring facilitates docking of the hook with the target sling.

[0009] Preferably, the hook further comprises an extension sleeve, which is fixedly connected to the outside of the hook body. The extension sleeve is used to increase the sliding guide range between the sliding bolt and the hook, thereby improving the sliding guide range of the sliding bolt.

[0010] Preferably, the hook further comprises a limit block fixedly connected to the inner end of the extension sleeve, so as to limit the sliding range of the sliding bolt and prevent the sliding bolt from completely detaching from the hook.

[0011] Preferably, the blocking lever comprises a rotating shaft and a rod body, wherein the rotating shaft is fixedly connected to the upper end of the rod body. The elastic force of the spring acts on the rod body through the rotating shaft, so that the rod body automatically maintains a closed state.

[0012] Preferably, the barrier rod further comprises a positioning block, which is symmetrically fixedly connected to the lower part of the rod body. The positioning block is wrapped around the sliding bolt to increase the contact range between the barrier rod and the sliding bolt, thereby improving the stability of the barrier rod in the closed state.

[0013] Preferably, the sliding bolt comprises an octagonal prism and a pull button, wherein a sliding groove is formed on the exterior of the octagonal prism, and the lower end of the octagonal prism is fixedly connected to the outer end of the pull button. Pulling the pull button outward causes the pull button to overcome the elastic force of the tension spring and drive the octagonal prism downward until the octagonal prism is retracted into the hook body, thereby releasing the sliding bolt from the blocking rod, allowing the blocking rod to avoid the rope.

[0014] In summary, the technical effects and advantages of the utility model are:

[0015] 1. Press the rope from the stop rod to the hook, so that the stop rod overcomes the elastic force of the spring to avoid the rope entering the hook. When the rope enters the gap between the hook and the stop rod, use the elastic force of the spring to drive the stop rod upward to return to its original position, pull the sliding bolt outward, so that the sliding bolt overcomes the tension spring and moves outward, so that the sliding bolt is retracted into the hook, and then pull the rope outward to make the stop rod avoid the rope, making it easier to remove the rope.

[0016] 2. The elastic force of the spring acts on the rod body through the rotating shaft, which makes it convenient for the rod body to automatically maintain a closed state. The positioning block is wrapped around the sliding bolt to increase the contact range between the blocking rod and the sliding bolt, thereby improving the stability of the blocking rod in the closed state.

[0017] 3. Pull the knob outward so that it overcomes the elastic force of the tension spring and drives the octagonal prism to slide downward until the octagonal prism is retracted into the hook body, causing the sliding bolt to unfasten the barrier rod, making it easier for the barrier rod to avoid the rope.
