Description

Technical Field

[0001] The invention relates to the field of steel pipe equipment, in particular to a rotating straddle carrier device. Background Art

[0002] In recent years, with the rapid development of domestic and foreign economies, energy demand has increased dramatically, and both international and domestic efforts to exploit oil and natural gas have been intensified. As an economical, safe, and uninterrupted long-distance transportation tool for oil and natural gas, oil and gas pipelines have developed rapidly. The production process of oil and gas pipelines includes multiple processes, and the production line occupies a huge area. During the production process, steel pipes need to be transported and transferred many times. Therefore, steel pipe transport vehicles are widely used in steel pipe production.

[0003] Traditional steel pipe transport vehicles can only move in a straight line along the track. Due to the limitation of the workshop columns, if the steel pipe is too long, it needs to be rotated 90 degrees to pass through the workshop columns. This results in the need for multiple steel pipe transport vehicles and overhead cranes to work together to complete the steel pipe transportation process when passing through the workshop columns. This steel pipe transportation method requires at least 3 transport vehicles and 2 overhead cranes, with complex procedures, low efficiency, troublesome maintenance and high costs. Summary of the invention

[0004] In view of the above-mentioned deficiencies in the prior art, an object of the present invention is to provide a rotating straddle carrier device.

[0005] To achieve the above objectives, the present invention adopts the following technical solutions:

[0007] Furthermore, the vehicle body I and the vehicle body II are connected via a connecting device I and a connecting device II;

[0008] Furthermore, the guide rail is fixed on the support and fixed by a pressure plate.

[0009] Furthermore, the driving wheels and the supporting wheels are evenly distributed below the vehicle body and symmetrically distributed on the same circumference and are concentric with the guide rails.

[0010] Furthermore, the lateral guide wheels are distributed on the same circumference.

[0011] Furthermore, the circular sliding wire device is cocentric with the circular guide rail.

[0012] Furthermore, the driving wheel is connected to the output shaft of the motor reducer.

[0013] Furthermore, the circular sliding wire device is fixed on the ground.

[0014] Preferably, the connecting device I and the connecting device II are both connecting plates with holes, and the vehicle body I and the vehicle body II are connected together respectively by bolts.

[0015] The working process of the rotating straddle carrier device comprises the following steps:

[0016] 1) Car body I and car body II are located on both sides of the workshop pillars. When the steel pipes on one car body reach the designated position, they are lifted away by the overhead crane, and the other car body is filled with steel pipes;

[0017] 2) The circular busbar device is powered on by control, the current collector contacts the busbar and transmits electricity to the motor reducer. After being powered on, the four motor reducers rotate and drive the four driving wheels to rotate. At this time, the car body I and the car body II move on the track. Restricted by the six lateral guide wheels, the car body I and the car body II move in a circle along the guide rail. After rotating 180 degrees, the device stops moving;

[0018] 3) The car body filled with steel pipes is moved from one side to the other side of the column and can be unloaded by the overhead crane. The car body that has been lifted by the overhead crane also moves from one side to the other side of the column and can be lifted by the overhead crane.

[0019] Repeat the above steps 1) to 3) to continuously move the steel pipe from one side of the column to the other side.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] The rotating straddle car device provided by the present invention enables the car body to make circular motion by controlling the rotation of the motor, and can transfer the steel pipes loaded on the car body from one side of the workshop column to the other side of the column. The transfer process does not require the cooperation of other equipment. At the same time, while one car body is loading steel pipes, the steel pipes on the other car body can be unloaded on the other side without affecting each other. The device has the advantages of large carrying capacity, high transfer efficiency, simple structure, high reliability, convenient maintenance and low cost. BRIEF DESCRIPTION OF THE DRAWINGS
