Description

Technical Field

[0001] The utility model relates to the technical field of pipeline cleaning, in particular to a pipeline cleaning device sending and receiving vehicle. Background Art

[0002] During the use of long-distance oil and gas pipelines, a large amount of impurities will be retained inside the pipelines due to the precipitation of the components of the pipeline medium itself and the corrosion of the pipe body itself. The accumulation of impurities will affect the pipeline transportation efficiency. To ensure the efficient operation of the pipeline, pipeline operating companies generally use pigs to regularly clean the pipelines. The pig sending and receiving trolley is a tool for receiving, sending and transporting pigs. It can transport the pigs to the front end of the pig sending device when preparing for pigging, or transport the pigs away from the receiving device after pigging.

[0003] Existing pipe cleaner sending and receiving vehicles are generally equipped with push-pull rods. When the pipe cleaner needs to be sent into the pipeline, the staff holds the push-pull rod and pushes the pipe cleaner from the trolley into the pipeline. However, the pipeline is often at a certain height, which is not convenient for manual completion of the pipe cleaner sending and receiving operation process. The staff needs to be sent to a certain height before the operation can be performed, resulting in reduced efficiency of the pipe cleaner's entry operation, which in turn affects the efficiency of pipeline cleaning.

When the walking assembly 6 rotates, it can drive the sending and receiving ball rod driving mechanism to move along the upper edge of the arc-shaped supporting mechanism 2, and then drive the sending and receiving ball rod 3 forward or backward, the auxiliary support member is arranged at intervals from the sending and receiving ball rod driving mechanism, the auxiliary support member is installed on the arc-shaped supporting mechanism 2, and the sending and receiving ball rod 3 slides with the auxiliary support member, through The auxiliary support member can prevent the sending and receiving ball rod 3 from being away from one end of the sending and receiving ball rod driving mechanism and deflecting downward during movement, thereby ensuring the stability of the sending and receiving ball rod 3 during movement; when the pipe cleaning tool is required to be sent and received, the lifting mechanism 1 can transport the arc-shaped supporting mechanism 2 to a specific height. At this time, the driving motor 4 works and drives the walking assembly 6 to rotate through the driving shaft 5. The walking assembly 6 can move forward or backward along the upper edge of the arc-shaped supporting mechanism 2 during rotation to drive the sending and receiving ball rod 3 forward, send the pipe cleaning tool into the pipeline, and complete the pipe cleaning tool entry operation. At the same time, when the pipe cleaning tool is discharged from the pipeline, the sending and receiving ball rod 3 can also be automatically retracted under the action of the sending and receiving ball rod driving mechanism, providing a storage space for the pipe cleaning tool in the arc-shaped supporting mechanism 2, so that the pipe cleaning tool can be accommodated in the arc-shaped supporting mechanism 2, thereby realizing the automation of the pipe cleaning tool sending and receiving operation. In this process, there is no need to manually pick up the sending and receiving ball rod 3, nor is there any need to manually adjust the position of the sending and receiving ball rod 3, thereby improving the efficiency of the pipe cleaning tool sending and receiving operation, thereby achieving the technical effect of improving the efficiency of pipeline cleaning.

[0027] As a preferred embodiment, the walking component 6 in the present application is a walking wheel, the wheel body of the walking wheel is in contact with the upper edge of the arc-shaped supporting mechanism 2, and the width of the walking wheel body is greater than the width of the upper edge of the arc-shaped supporting mechanism 2, thereby ensuring the stability of the sending and receiving club driving mechanism during operation; in order to further improve the stability of the walking wheel during movement, limit baffles are provided on both axial sides of the walking wheel, and the limit baffles are respectively located on the inner and outer sides of the upper edge of the arc-shaped supporting mechanism 2.

[0032] More preferably, the auxiliary support member also includes a front support vertical rod 10, the upper end of the front support vertical rod 10 is connected to the front support cross rod 9, and the lower end of the front support vertical rod 10 is abutted against the inner wall of the arc-shaped supporting mechanism 2. The front support vertical rod 10 can provide an upward support force for the front support cross rod 9, further improving the stability of the sending and receiving club 3 during operation.

[0033] Preferably, the output shaft of the driving motor 4 and the driving shaft 5 are connected by a gear transmission, and the gear transmission has the advantages of small size, stable transmission, and large traction.

[0034] Those skilled in the art will appreciate that the output shaft of the drive motor 4 and the drive shaft 5 may also be connected using existing connection methods such as belt connection and sleeve connection, which are not specifically limited herein.

A connecting through hole is provided on the connecting groove, and a pin hole is provided on the connecting portion corresponding to the connecting through hole. When the connecting portion is inserted into the connecting groove, the two can be connected together by a pin shaft, thereby realizing a detachable connection between the sending and receiving club 3 and the sending and receiving club driving mechanism, so that sending and receiving clubs 3 of different sizes can be replaced as needed.
