Description

Technical Field

[0001] The invention relates to an artificial pipeline transportation auxiliary device, in particular to a transportation auxiliary device for short-distance transportation of irregular pipelines. Background Art

[0002] Existing pipeline transportation mainly relies on hoisting and vehicle transportation. The pipeline needs to be hoisted onto the vehicle, then transported to the designated location and then hoisted off the vehicle. This has special requirements for the road conditions at the construction site and the selection of the hoisting site. When construction conditions are limited, manpower is needed to transfer the pipeline, making construction difficult.

[0003] The Chinese patent with publication number CN219651199U and application date 20221121 discloses a "heating pipe transport trolley group", the heating pipe length is not less than 2.5m, including a plate-type trolley for carrying the front end of the heating pipe and a cart for carrying the rear end of the heating pipe; the cart includes rollers, an axle connecting the rollers on both sides, a frame provided on the axle, and an arc-shaped bucket fixed on the frame; the plate-type trolley includes a car plate, wheels provided at the bottom of the car plate, a frame provided on the car plate, and an arc-shaped groove fixed on the frame, the arc-shaped groove has the same horizontal elevation as the bottom of the arc-shaped groove of the arc-shaped bucket, and pipe clamps are provided on the front and rear sides of the arc-shaped groove and the car plate. However, this structure cannot meet the requirements of pipeline deformation. Summary of the invention

[0004] The purpose of the present invention is to overcome the shortcomings of the prior art and provide an artificial auxiliary device for pipeline transportation which is easy to operate, adaptable to pipeline deformation and protects the road surface.

[0006] The present invention provides an artificial auxiliary device for pipeline transportation, comprising at least two transportation auxiliary devices arranged at a front-rear interval, each transportation auxiliary device comprising a transportation vehicle, a bottom of a supporting structure connected to a frame of the transportation vehicle, a bottom of a pipe clamp rotatably connected to a top of the supporting structure and fixedly connected to the supporting structure at a set angle by bolts, and a rubber buffer pad is arranged on the inner wall of the pipe clamp.

[0007] Beneficial effects of the present invention:

[0008] (1) The device has a simple structure. When the shape of the pipeline is complex, the angle of the pipe clamp can still be adjusted to adapt to the deformation of the pipeline;

[0009] (2) The device is easy to install and can be installed and positioned by tightening bolts, making it easy to operate;

[0010] (3) The device can be used flexibly by increasing or decreasing the number of devices put into use according to the length of the pipeline;

[0011] (4) The wheels of this device are designed to be rubber wheels, and the contact part between the pipe clamp and the pipe is also rubber, which fully protects the pipe, has strong adaptability to terrain, has low noise, and protects the transportation road surface.

[0016] The present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0017] As shown in the accompanying drawings, a manual auxiliary device for pipeline transportation of the present invention includes at least two transportation auxiliary devices arranged at intervals in front and behind, each transportation auxiliary device includes a transport vehicle, a bottom of a supporting structure 4 is connected to the frame of the transport vehicle, and the bottom of the pipe clamp 1 is rotatably connected to the top of the supporting structure 4 and is fixedly connected to the supporting structure at a set angle by bolts 3. A rubber buffer pad 2 is arranged on the inner wall of the pipe clamp. The rubber buffer pad is located on the inner side of the pipe clamp, forming an isolation between the pipe and the pipe clamp, preventing the pipe from directly contacting the pipe clamp during transportation, protecting the pipe and reducing noise.

[0018] The supporting structure may include a steel column with a connecting hole on the upper part of the steel column. The bottom of the pipe clamp and the top of the upper part of the steel column can be rotatably connected and connected by bolts passing through the connecting hole. The lower part of the steel column is welded to the channel steel to support the upper structure and connect the lower structure. The length of the steel column can be adjusted as needed, and the channel steel can be used as a frame of a transport vehicle.

[0019] The transport vehicle may generally adopt an existing structure, such as comprising a frame, wherein the left side and the right side of the frame are rotatably connected to two wheels 5 respectively.

[0020] As an implementation structure of the present invention, the bottom of the pipe clamp has an n-shaped groove, the top of the supporting structure (steel column) can be inserted into the n-shaped groove, and the pipe clamp can rotate around the top of the supporting structure (steel column) through the n-shaped groove and be fixed at a set position by bolts.

[0021] Furthermore, the pipe clamp includes two semicircular bodies of the same structure, which are fitted together to form a whole circular body, which is used to confine the pipeline in the pipe clamp. The two semicircular bodies are connected by bolts, and a flange plate is arranged at the bottom of each semicircular body. The flange plates of the two semicircular bodies are arranged relative to each other to form an n-shaped groove. The top of the supporting structure (steel column) can be inserted into the n-shaped groove, and the pipe clamp can be rotated around the top of the supporting structure (steel column) through the n-shaped groove and fixed in a set position by bolts. Bosses are respectively arranged on the top of the two semicircular bodies, and a lifting hole is opened in the middle of the boss. When lifting is required, the rope can be directly inserted into the lifting adjustment or transportation. The length of the pipe clamp can be flexibly adjusted to achieve weight reduction.

[0022] Furthermore, the pipe clamp and supporting structure of the device are both made of steel.

[0023] Furthermore, the tires of the wheels of the transport vehicle are made of hollow rubber material, which has wear-resistant and inflation functions, and the elastic wheels can adapt to complex terrain, reduce noise, and reduce damage to the road surface.

[0024] Furthermore, a lifting lug is provided on the upper portion of the pipe clamp.

[0025] The method of using this device is:

[0026] In the hoisting site, insert both ends of the pipe into the pipe clamps and then loosen the pipe to let it naturally rest on the rubber buffer pad. Adjust the angle of the pipe clamp according to the state of the pipe to fix the angle of the pipe clamp in accordance with the state of the pipe. Tighten the bolts to complete the installation. After installing a device on each of the two sections of the pipe, it can be moved. If the pipe is too long, the device can be installed in the middle part of the pipe according to demand. The movement of the pipe can be powered by human pulling to pull the pipe to the work site.

[0027] The above-mentioned specific implementations are merely illustrative rather than restrictive. Under the guidance of the present invention, ordinary technicians in this field can make many modifications without departing from the spirit of the present invention and the scope of protection of the claims, all of which are protected by the present invention.
