Description

Technical Field

[0001] The utility model relates to the technical field of pipeline laying, in particular to a pipeline laying traction device. Background Technique

[0002] China is a large agricultural country and attaches great importance to farmland water conservancy work. A series of major measures have been taken to develop irrigation and drainage, regulate the water regime in regions, improve the moisture conditions of farmland, and prevent and control drought, waterlogging, salt and alkali disasters, so as to promote stable and high-yield agriculture. During the process of farmland water conservancy construction, it is often necessary to lay cement pipelines, and at this time, the cement pipelines need to be moved to the laying site.

[0003] After retrieval, a water conservancy construction pipeline laying traction device disclosed in a Chinese patent with the publication number CN214305561U has the following technical key points: It solves the problem that the existing method of moving cement pipelines has certain limitations. Since the cement pipelines are heavy, it is necessary for workers to bend down and push the cement pipelines by hand to roll. During the rolling process of the cement pipelines, their direction is prone to deviation. If the distance to the laying site is far, bending down for a long time will increase the labor intensity of construction workers.

[0004] However, in the above scheme and existing pipeline laying traction devices, due to the variety of pipeline types on the market, the sizes and calibers of the pipelines laid each time are different. The above scheme and existing devices cannot clamp and traction pipelines of different sizes, resulting in low applicability.

[0005] Therefore, a new scheme needs to be proposed to solve this problem. Content of the Utility Model

[0006] In view of the deficiencies and defects in the above background technique that the existing technology cannot clamp and traction pipelines of different sizes, resulting in low applicability.

A worm gear is meshed on the outer surface of the worm. A bidirectional threaded rod is fixedly connected to the inner wall of the worm gear. Two sliding blocks are threadedly connected to the outer surface of the bidirectional threaded rod. A support plate is fixedly connected to the upper surface of each sliding block. A clamping member one is fixedly connected to the upper surface of one of the support plates. Two clamping members two are fixedly connected to the upper surface of the other support plate. Two pulley columns are fixedly connected to the inner wall of each support plate.

[0008] Furthermore, a support member is fixedly connected to the bottom surface of the motor. The inner wall of the support member is rotationally connected to the outer surface of the worm. An installation plate is fixedly connected to the left side surface of the support member. The inner wall of the installation plate is rotationally connected to the outer surface of the bidirectional threaded rod.

[0009] Furthermore, sliding grooves and two limiting grooves are formed on the upper surface of the mounting plate, and the outer surface of each sliding block is slidably connected to the inner wall of the sliding groove.

[0010] Furthermore, a bottom plate is provided below the mounting plate. A set of wheels arranged at equal distances are fixedly installed on the bottom surface of the bottom plate, and a set of support rods arranged at equal distances are fixedly connected to the upper surface of the bottom plate.

[0011] Furthermore, two connecting plates I and two connecting plates II are provided above the bottom plate, and the top end of each support rod is fixedly connected to the bottom surfaces of the corresponding connecting plates I and II.

[0012] Furthermore, a spring is fixedly connected to the upper surface of each connecting plate I, and the top end of each spring is fixedly connected to the bottom surface of the mounting plate.

[0013] Furthermore, a damping rod is fixedly installed on the upper surface of each connecting plate I, and the top end of each damping rod is fixedly installed on the bottom surface of the mounting plate.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0015] 1. By providing components such as a worm, a worm gear, a bidirectional threaded rod, sliding blocks, a support plate, a clamping member I, and a clamping member II, the present utility model drives the worm to rotate through a motor. Through the connection between the worm and the worm gear, the rotation effect of the worm gear is achieved.

The support plates drive the corresponding clamping member I and clamping member II to move relatively. By installing pulley columns, the support and limitation of the support plates are realized. While considering the shapes and placement positions of the clamping member I and the clamping member II, the present device can clamp and tow pipes of different sizes, improving the applicability of the device.

[0016] 2. By providing components such as springs, damping rods, support rods, connecting plates I, and connecting plates II, and installing the set of wheels on the bottom surface of the bottom plate. When the device is moved and towed through the set of wheels, when passing through bumpy sections, due to the installation of the support rods, connecting plates I, and connecting plates II, the support for the springs and damping rods is realized. Through the installed connecting plates I and II, the limitation effect on the mounting plate is achieved.
