Description

Technical Field

[0001] The utility model relates to the technical field of drainage pipeline construction, and particularly relates to a horizontal hoisting device for large-diameter concrete pipes. Background Art

[0002] Concrete pipes are pipes made of concrete or reinforced concrete, mainly used for transporting fluids such as water, oil, and gas. When installing concrete pipes, they need to be hoisted to a designated position for installation. Since concrete pipes are usually hollow tubular, it is usually necessary to use a hoisting clamp to hold the concrete pipe during hoisting, so as to facilitate the hoisting of the concrete pipe. However, during the process of clamping the concrete pipe by the current concrete pipe hoisting clamp, due to insufficient limitation of the hoisting clamp, it is easy to loosen during the hoisting of the concrete, which affects the safety and stability of the hoisting of the concrete pipe and is prone to certain potential safety hazards. Content of the Utility Model

[0003] To solve the above technical problems, the utility model provides a horizontal hoisting device for large-diameter concrete pipes.

[0004] The technical solution of the utility model is realized as follows:

[0005] A horizontal hoisting device for large-diameter concrete pipes includes a pipe turning hook and an ear pin. The pipe turning hook is in a "C" shape and is used to put on the end of the concrete pipe. The ear pins are installed on both sides of the concrete pipe. The pipe turning hook and the ear pins are respectively connected to a suspension tool through a first steel wire rope and a second steel wire rope.

[0006] Further, the pipe turning hook includes an upper clamping part, a lower clamping part, a turning arm, and a first stop bar. The upper clamping part is sleeved on the lower clamping part in a liftable manner. The turning arm is rotatably installed on the lower clamping part, and the bottom end of the turning arm presses on the upper clamping part.

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] As Figure 1 shown, a horizontal hoisting device for large-diameter concrete pipes provided in the first embodiment of the present invention includes a pipe turning hook 1 and an ear pin 2. The pipe turning hook 1 is in a "C" shape and is used to put on the end of the concrete pipe. The ear pins 2 are installed on both sides of the concrete pipe. The pipe turning hook 1 and the ear pins 2 are respectively connected to a suspension device through a first steel wire rope 3 and a second steel wire rope 4.

[0023] Specifically, the suspension device can be formed by a plate body and a lifting lug. The lifting lug is used to directly connect to the hook of the hoisting machine. The tops of the first steel wire rope 3 and the second steel wire rope 4 are connected to the suspension device.

[0024] When hoisting a concrete pipe, two ear pins 2 can be installed on both sides of the concrete pipe by screws first. Then, the bottoms of the two first steel wire ropes 3 are respectively connected to the two ear pins 2, and then the pipe turning hook 1 is put on the end of the concrete pipe. Then, the concrete pipe can be directly hoisted.

[0025] During the operation of docking concrete pipes, when it is necessary to adjust the angle of the docking end of the concrete pipe, the concrete pipe can be placed on the ground first, then the pipe turning hook 1 is pulled out of the pipe, and then the concrete pipe is re-hoisted with the help of a safety rope and the ear pins 2. After adjusting to the appropriate displacement, the pipe turning hook 1 is reinserted, and then it is docked with the previously installed concrete pipe again.

[0026] As Figure 2 and Figure 3 shown, in the second embodiment, the pipe turning hook 1 includes an upper clamping part, a lower clamping part, a rotating arm 1.1 and a first stop bar 1.2. The upper clamping part is sleeved on the lower clamping part in a liftable manner. The rotating arm 1.1 is rotatably installed on the lower clamping part. The bottom end of the rotating arm 1.1 presses on the upper clamping part. The first stop bar 1.2 is fixedly installed at the top end of the lower clamping part. The bottom end of the first steel wire rope 3 bypasses the bottom of the first stop bar 1.2 and is connected to the top end of the rotating arm 1.1.

[0027] When lifting the concrete pipe, the first steel wire rope 3 pulls the top of the rotating arm 1.1, so that the rotating arm 1.1 can press down the upper clamping part with the help of the concrete pipe's own weight. Then, the upper clamping part and the lower clamping part cooperate to clamp the end of the concrete pipe. At the same time, during the process of lifting the concrete pipe, the pipe-turning hook 1 can maintain a stable clamping effect on the concrete pipe, thereby improving the safety and stability of the concrete pipe lifting.

[0028] The first baffle 1.2 makes the part of the first steel wire rope 3 between the first baffle 1.2 and the rotating arm 1.1 tend to be horizontal, so that the angle between the first steel wire rope 3 and the top of the first baffle 1.2 and the rotating arm 1.1 is smaller, so that the first steel wire rope 3 can better convert the gravity of the concrete pipe into the force of the rotating arm 1.1 pressing down on the clamping part, thereby improving the clamping effect of the pipe-turning hook 1 on the concrete pipe.

[0029] The upper clamping section includes a slide 1.3 and two upper clamping rods 1.4, which are mounted side by side on the front side of the slide 1.3. When the upper clamping section clamps a concrete pipe, the two upper clamping rods 1.4 provide two symmetrically distributed clamping points on the concrete pipe, improving the clamping effect and stability of the concrete pipe.

[0030] The lower clamping section includes a support base 1.5 and two lower clamping rods 1.6, which are mounted side by side on the front side of the support base 1.5. The slide 1.3 slides vertically over the support base 1.5. When the lower clamping section clamps a concrete pipe, the two lower clamping rods 1.6 provide two symmetrically distributed clamping points, improving the clamping effect and stability.

[0031] The rotating arm 1.1 is rotatably mounted inside the supporting base 1.5, and the bottom end of the rotating arm 1.1 is rotatably connected to the hinged base 1.7, which is slidably mounted on the upper surface of the sliding base 1.3. The hinged base 1.7 effectively connects the bottom end of the rotating arm 1.1 with the sliding base 1.3.

[0032] A second baffle 5 is installed on the top of the support seat 1.5. The height of the second baffle 5 is greater than that of the first baffle 1.2. The second baffle 5 is located between the rotating arm 1.1 and the first baffle 1.2 in the front-to-back direction. The bottom end of the first steel wire rope 3 passes around the bottom of the second baffle 5 from back to front and then passes around the bottom of the first baffle 1.2 from front to back.

[0033] Specifically, the first stopper 1.2 is mounted on top of the support base 1.5 in a sliding manner in the forward and backward directions. The support base 1.5 is provided with an adjustment structure that drives the forward and backward displacement of the first stopper 1.2. By operating the adjustment structure to control the forward and backward displacement of the first stopper 1.2, the length of the first steel wire rope 3 can be adjusted to adjust the height of the end of the concrete pipe clamped by the pipe-turning hook 1. This allows the butt end of the concrete pipe to swing up and down with the ear pin 2 as a fulcrum while it is suspended, further facilitating the docking operation of the concrete pipe.

[0034] The adjustment structure includes an adjustment bolt 6 and an adjustment seat 7. The adjustment seat 7 is slidably mounted on top of the support seat 1.5. The first stopper 1.2 is fixedly mounted on top of the adjustment seat 7. The adjustment bolt 6 is rotatably mounted on top of the support seat 1.5, and the adjustment bolt 6 and the support seat 1.5 are threadedly engaged. By rotating the adjustment bolt 6, the position of the first stopper 1.2 can be controlled through the adjustment seat 7, thereby adjusting the length of the first steel wire rope 3, thereby adjusting the concrete pipe.

[0035] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
