Description

Technical Field

[0001] This utility model relates to the field of construction safety technology, specifically to a hoisting safety device. Background Technology

[0002] During construction, various types of pipes are often used. Due to the significant differences in the actual dimensions of these pipes, appropriate cranes are typically used to operate them according to the specific needs of the construction site. Existing pipe hoisting methods often rely on ropes for securing the pipes, either by passing the ropes through the pipes or by tying them to both ends. This method is prone to uneven stress on the pipes during transport due to factors such as wind at high altitudes and collisions. This can cause the pipes to sway, loosen the securing ropes, and lead to tilting or even slippage of the pipes. This makes it difficult to control the pipes in time, and excessive pulling on the ropes during hoisting can cause them to snap and fall, resulting in a safety accident. Utility Model Content

[0003] The purpose of this utility model is to provide a safety device for hoisting, which solves the problem of uneven force on both ends of the pipe causing swaying, tilting or even slippage when using rope hoisting.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A hoisting safety device includes a support plate with two lifting straps below it. Each of the two lifting straps is connected to an upper horizontal column on its lower side. A vertical column is vertically connected to the opposite end of each of the two upper horizontal columns. A lower horizontal column parallel to the upper horizontal column is connected to the opposite side of the lower end of each vertical column. Both vertical columns are connected to the support plate via spring telescopic rods.

[0006] A further technical solution is that connecting columns are horizontally installed on the lower sides of both ends of the receiving plate through connecting grooves, and the upper ends of the spring telescopic rods on the two straight columns are provided with hanging rings for connecting the connecting columns.

[0007] A further technical solution is that a hook is provided at the lower end of the sling, and a second eye bolt is provided vertically upward through a second threaded hole on the upper side of the upper crossbar, with the hook connected to the second eye bolt.

[0008] A further technical solution is that the upper side of the straight column is provided with a first fixing hole corresponding to the upper horizontal column, and the upper horizontal column is fixedly connected to the first fixing hole.

[0009] A further technical solution is that a second fixing hole is horizontally provided on the upper side of the straight column corresponding to the lower horizontal column, and the lower horizontal column is fixedly connected to the second fixing hole.

[0010] A further technical solution is that a friction element is provided at the end of the lower horizontal column away from the vertical column, and the friction element is movably connected to the lower horizontal column through a spherical movable joint; a rubber block is provided above the friction element.

[0011] A further technical solution is that the spherical movable joint includes a retainer, a movable ball, and a fixed post. The retainer is installed at the end of the lower horizontal column away from the vertical column. The movable ball is rotatably connected to the retainer. The fixed post is fixedly set on the surface of the movable ball. A third fixing hole is provided on the side of the friction component corresponding to the fixed post. The third fixing hole is fixedly connected to the fixed post.

[0012] A further technical solution is that a balance bar is horizontally installed on the side of the straight column, and a first eye bolt is vertically installed at both ends of the balance bar; the balance bar is fixedly connected to the first eye bolt through a first threaded hole; a hook is installed at the lower end of the spring telescopic rod, and the hook is fixedly connected to the first eye bolt.

[0013] A further technical solution is to install a third lifting eye screw on the top of the receiving plate through a third threaded hole for lifting the entire device.

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0022] Example 1:

[0023] A hoisting safety device includes a receiving plate 1. Two lifting straps 11 are positioned below the receiving plate 1. Each of the two lifting straps 11 has an upper horizontal column 4 connected to its lower side. A vertical column 3 is vertically connected to the opposite end of each upper horizontal column 4. A lower horizontal column 5, parallel to the upper horizontal column 4, is connected to the opposite side of the lower end of each vertical column 3. Both vertical columns 3 are connected to the receiving plate 1 via a spring telescopic rod 7. The receiving plate 1 serves as an intermediate component. Hoisting components for different hoisting devices can be added above the receiving plate 1, such as a magnetic suction plate for hoisting with an electromagnet, to adapt to other hoisting devices and increase the device's versatility. During hoisting, the lower horizontal column 5 extends into and abuts against the inner wall of the pipe, while the middle of the upper horizontal column 4 abuts against the outer wall of the pipe, clamping and fixing the pipe. Hoisting is performed in conjunction with the lifting straps 11, and the spring telescopic rod 7 promptly stops the swaying of the pipe during hoisting, preventing the lower horizontal column 5 from slipping or even detaching from the inner wall of the pipe, ensuring the pipe remains relatively stable during hoisting.

[0024] Example 2:

[0025] Connecting posts 9 are horizontally arranged on the lower sides of both ends of the receiving plate 1 via connecting grooves 8. The upper ends of the spring telescopic rods 7 on the two straight posts 3 are each provided with a hanging ring 10 for connecting the connecting posts 9. The connecting grooves 8 are used to reserve space for the hanging rings 10 to rotate on the connecting posts 9. Four connecting grooves 8 are provided below the receiving plate 1, with two connecting grooves 8 evenly distributed at both ends. Two connecting posts 9 and two hanging rings 10 are provided at each end corresponding to the two connecting grooves 8.

The hook 12 is connected to the second eye bolt 20. The sling 11, hook 12 and second eye bolt 20 are used for transmission and lifting. While lifting the support plate 1, the sling 11 is straightened, thereby lifting the fixed pipe.

[0028] Example 4:

[0029] The upper side of the straight column 3 is provided with a first fixing hole 22 corresponding to the upper horizontal column 4. The upper horizontal column 4 is fixedly connected to the first fixing hole 22. The upper horizontal column 4 is welded to the straight column 3 at the first fixing hole 22.
