Description

Technical Field

[0001] The utility model relates to the technical field of municipal engineering machinery and equipment, and more specifically to the technical field of municipal engineering machinery and equipment. Background Art

[0002] During the processing, transportation and hoisting of municipal engineering pipelines, especially the hoisting of pre-buried sewage pipes, rainwater pipes, etc., multiple people are required to cooperate to fix the lifting slings at both ends of the circular pipe, and then use a lifting machine to lift it. If the binding is not firm during the binding process, it is very easy to fall and be damaged during transportation. After transporting to the installation groove position, workers are required to untie the binding slings, which leads to low lifting efficiency. In addition, due to the narrowness of the operating groove, it is difficult to untie the slings.

[0003] If the sling is not tied firmly or unbalanced, it is easy to damage, especially for prefabricated circular pipes. When the lifting wire rope is used, it is easy to cause damage to the pipe. How to solve this problem has become an urgent problem to be solved. Utility Model Content

[0004] The purpose of the utility model is to solve the technical problems that conventional lifting with slings requires the assistance of multiple people and the cumbersome process of frequently tying and releasing the slings, and to provide a quick hoist for circular pipes. The hoist can realize efficient and quick lifting of circular prefabricated pipes and circular plastic pipes.

[0005] In order to achieve the above-mentioned purpose, the utility model specifically adopts the following technical solutions:

[0006] The utility model provides a quick hoist for a circular pipe, comprising a support rod, an opening and closing mechanism arranged on the support rod and lifting the circular pipe in an opening and closing manner, and a driving mechanism driving the opening and closing mechanism to work, wherein a main hoisting ring connected with a crane is arranged at the bottom of the support rod.

[0007] Specifically, the circular pipe is a component that needs to be lifted and installed by this hoist at the construction site, and can be a prefabricated pipe or a circular pipe made of plastic.

[0008] The main lifting ring is located at the top of the support rod and is made of a hollow arc iron ring. It is designed for installing wire ropes and is mainly used when the circular pipe needs to be lifted into a deeper foundation pit and the support rod is not long enough.

[0009] In one embodiment, the opening and closing mechanism includes a bottom disc fixedly arranged at the bottom of the support rod, a top disc movably sleeved on the support rod, and a plurality of telescopic claws evenly distributed between the bottom disc and the top disc.

[0010] Specifically, the support rod is connected to the bottom disc as a whole, and cooperates with the stabilizing sleeve to provide a basis for smoothly lifting the circular pipe and bearing the weight of the pipe.

[0011] In one embodiment, a through hole is provided in the middle of the top disc, a stabilizing sleeve is provided in the through hole, and the supporting rod slides through the stabilizing sleeve.

[0012] Specifically, the stabilizing sleeve is located in the middle of the top disc and is composed of a small section of circular steel pipe, which is connected to the top disc to form a whole. The stabilizing sleeve is used to ensure the stability of the support rod passing through the middle and to achieve the telescopic fixation of the support rod.

[0013] In one embodiment, auxiliary lifting rings are provided on the top discs on both sides of the stabilizing sleeve, and each auxiliary lifting ring is connected to the crane through a steel wire rope.

[0014] Specifically, the auxiliary lifting rings are located on both sides of the stabilizing sleeve and are welded to the top disc in a C shape. They are mainly used for wire ropes to disperse the gravity on the bottom disc and support rods when lifting by cranes, so that the top disc is also subjected to force, ensuring the smooth lifting of large pipelines.

[0015] One end of the wire rope is tied and fixed to the auxiliary lifting ring and the main lifting ring, and the other end is fixed to the lifting machine. By mechanically acting on the wire rope, the installation of foundation pit pipes of different depths can be achieved, and the on-site disassembly and practical use of the lifting device are also convenient.

[0016] In one embodiment, the opening and closing mechanism includes a first base arranged on the top of the bottom disc, a fixed claw hinged to the first base, a second base fixed to the bottom of the top disc, and a supporting claw hinged to the second base, and the free end of the fixed claw intersects with the free end of the supporting claw.

[0017] In one embodiment, the first base includes two square steel sheets arranged side by side, a circular hole for installing a latch is arranged in the middle of the two steel sheets, and the supporting claw is hinged between the two steel sheets.

[0018] Specifically, the first base is located at the bottom of the bottom disc and is composed of a square steel sheet. A circular hole for installing a pin is designed in the middle of the steel sheet. This first base has a total of five groups of steel sheets, each group involving two steel sheets. This first base provides a foundation for the installation of the support claw.

[0019] In one embodiment, the fixing claw is a steel sheet with an elliptical end and a triangular end. The elliptical end of the fixing claw is hinged to the first base, the triangular end of the fixing claw is hinged to the supporting claw, and the triangular end of the fixing claw cooperates with the inner wall of the circular pipe.

[0020] Specifically, one end of the fixing claw is an elliptical steel sheet and the other end is a triangular steel sheet. A circular hole for a pin is designed at both ends. It is specially designed for installation with the first base and the supporting claw through a pin. The design size of the fixing claw must match the inner diameter of the circular pipe that needs to be lifted. The triangular end of the fixing claw interacts with the inner wall of the circular pipe to achieve rapid lifting and placement of the circular pipe.

[0021] In one embodiment, the second base includes a square steel sheet, a circular hole for installing a latch is provided in the middle of the steel sheet, and the supporting claw is hinged on the square steel sheet.

[0022] Specifically, the first base is located at the bottom of the top disc and is composed of a square steel sheet. A circular hole for installing a pin is designed in the middle of the steel sheet. This first base has a total of five groups of steel sheets, each group involving a steel sheet. This first base provides a foundation for the installation of the support claw.

[0023] In one embodiment, the supporting claw comprises two elliptical steel sheets arranged in parallel, and one triangular end of the fixing claw is hinged between the two steel sheets of the supporting claw.

[0024] Specifically, the design size of the supporting claw needs to match that of the fixing claw, and the lifting and placement of the circular pipe can be achieved by cooperating with the supporting claw and the fixing claw.

[0025] In one embodiment, the bottom disc is a circular steel disc made of steel, and the top disc is a circular steel disc made of steel.

[0026] The beneficial effects of the utility model are as follows:

[0027] With this quick lifter, there is no need for multiple people to participate in the lifting process of the circular pipe, nor is there any need to frequently tie and untie the slings. The circular prefabricated pipe can be lifted and transported quickly and easily, and it is easy to install the narrow circular prefabricated pipe. Then, the lifter can effectively contact the inner wall of the pipe to prevent the pipe from being damaged during the lifting process, which is particularly suitable for prefabricated pipes.
