Description

Technical Field

[0001] The utility model belongs to the technical field of pipe body processing tooling, and particularly relates to a supporting wheel working platform for pipe body positioning. Background Art

[0002] Ductile iron pipe is a kind of cast iron pipe. In terms of quality, the spheroidization grade of the cast iron pipe is required to be controlled at levels 1-3, and the spheroidization rate is greater than 80%. Therefore, the mechanical properties of the material itself have been improved, and it has the essence of iron and the performance of steel. After annealing, the metallographic structure of the ductile iron pipe is ferrite plus a small amount of pearlite, with good mechanical properties, excellent anti-corrosion performance, good ductility, good sealing effect, and easy installation. It is mainly used for water supply, gas transmission, and oil transmission in municipal and industrial and mining enterprises.

[0003] The problem of the prior art is that during the production process of metal pipe bodies, it is necessary to apply anti-corrosion coatings on the outer wall of the pipes. Usually, a supporting wheel group is used to support and position the pipe body in a rotational manner. However, during the rotation of the pipe body, axial movement is likely to occur, affecting the positioning of the pipe body, resulting in an impact on the coating work, and there is a risk of the pipe body falling off the supporting wheel group; the length of the existing supporting wheel group is fixed and cannot be adjusted according to the length of the pipe body, resulting in a small applicable range, inconvenient use, or the need to set up multiple wheel groups, and the structure is relatively complex. Summary of the Invention

[0004] The purpose of the utility model is to provide a supporting wheel working platform for pipe body positioning, which has the advantages of stable positioning, convenient use, and simple structure, aiming at the problems existing in the prior art.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is: a supporting wheel working platform for pipe body positioning, including a supporting wheel base. On the top surface of the supporting wheel base, there are provided an active supporting wheel group and a driven supporting wheel group. The active supporting wheel group is connected with a power mechanism. The active supporting wheel group and the driven supporting wheel group respectively include supporting wheels for supporting the pipe body. On the top surface of the supporting wheel base, there is provided a retaining wheel mechanism. The retaining wheel mechanism includes a rotating retaining wheel for cooperating with the end face of the pipe body. The wheel axles of the driven supporting wheel group are arranged at a set angle to generate an axial moving force on the pipe body towards the retaining wheel mechanism. On the top surface of the supporting wheel base, there are provided a number of spacing adjustment holes and grooves. The active supporting wheel group and / or the driven supporting wheel group are installed at the spacing adjustment holes and grooves through a first threaded fastener.

[0006] In the above solution, the driving idler wheel group and the driven idler wheel group are connected and positioned through the idler wheel base. The driving mechanism drives the supporting idler wheels on the driving idler wheel group to rotate, thereby driving the pipe body to rotate. By controlling the axial directions of the driven idler wheel group and the driven idler wheel group, an axial force is generated during the rotation of the pipe body, causing the pipe body to axially move in a specific direction towards the retaining wheel mechanism during rotation. The rotating retaining wheel of the retaining wheel mechanism is used to block and limit the end face of the pipe body, ensuring the rotational stability of the pipe body. The installation and positioning of the driving idler wheel group and / or the driven idler wheel group are facilitated through the spacing adjustment holes and grooves on the top surface of the idler wheel base in cooperation with the first threaded fastener, which is convenient for adjusting the spacing between the driving idler wheel group and the driven idler wheel group according to the length of the pipe body, and has a wide range of applications.

[0012] By providing the wheel group support to fix the wheel shaft mounting seat, and using the bearing seats on the wheel shaft mounting seat to rotatably connect with the wheel shaft of the supporting idler wheel, the structure is simple and the setting is convenient.

[0013] Further, the driving mechanism includes a motor, the motor is connected with a reducer, and the reducer is connected with the driving idler wheel group.

[0014] The motor drives the supporting idler wheels of the driving idler wheel group to rotate through the reducer, thereby driving the pipe body to rotate, which is convenient for processing the pipe body.

[0015] Further, a transmission part is provided on the wheel shaft of the supporting idler wheel of the driving idler wheel group, the reducer is connected with a chain, and the chain is connected with the transmission part.

[0016] The motor power is transmitted to the supporting idler wheel through the chain of the reducer and the transmission part on the wheel shaft of the supporting idler wheel of the driving idler wheel group, and the structure is simple.

[0017] Furthermore, two L-shaped protective baffles are connected to the supporting wheel base through bolt assemblies. The L-shaped protective baffles include a horizontal plate and a vertical plate. The vertical plates of the two L-shaped protective baffles are located on both sides of the pipe body, and strip-shaped positioning grooves for cooperating with the bolt assemblies are formed on the horizontal plates.

[0018] The two sides of the pipe body are blocked and limited by the vertical plates of the L-shaped protective baffles, preventing the pipe body from slipping off the supporting wheel set and ensuring on-site safety.

The top surface of the idler wheel base 1 is provided with a driving idler wheel set 2 and a driven idler wheel set 3. The driving idler wheel set 2 is connected with a power mechanism. The driving idler wheel set 2 and the driven idler wheel set 3 respectively include supporting idler wheels 4 for supporting the pipe body 16. The top surface of the idler wheel base 1 is provided with a retaining wheel mechanism. The retaining wheel mechanism includes a rotating retaining wheel 5 for cooperating with the end face of the pipe body 16. The wheel shaft of the driven idler wheel set 3 and the wheel shaft of the driven idler wheel set 3 are set at a set angle to generate an axial moving force on the pipe body 16 towards the retaining wheel mechanism. A plurality of spacing adjustment holes are opened on the top surface of the idler wheel base 1. The driving idler wheel set 2 and / or the driven idler wheel set 3 are installed at the spacing adjustment holes through the first threaded fasteners 7.

[0034] In the above solution, the driving idler wheel set 2 and the driven idler wheel set 3 are connected and positioned by the idler wheel base 1. The driving mechanism drives the supporting idler wheel 4 on the driving idler wheel set 2 to rotate, thereby driving the pipe body 16 to rotate. By controlling the axial direction of the driven idler wheel set 3 and the driven idler wheel set 3, an axial force is generated during the rotation of the pipe body 16, causing the pipe body 16 to axially move in a specific direction towards the retaining wheel mechanism during rotation. The rotating retaining wheel 5 of the retaining wheel mechanism is used to block and limit the end face of the pipe body 16, so as to keep the rotation stability of the pipe body 16.
