TECHNICAL FIELD

[0001] The utility model relates to oil transfer arm accessory technology field, concretely is a damping system for crane pipe. BACKGROUND

[0002] In the loading process of petrochemical products, as a key oil transfer equipment, the performance and operation convenience of crane pipe are crucial to improve loading efficiency and safety;

[0003] Traditional crane pipe design often does not have damping system, resulting in when the outrigger of crane pipe is connected with tank truck, due to the gravity moment generated by the outrigger itself, the operator needs to spend a lot of effort to adjust it to the horizontal position, which not only increases the complexity of operation, but also needs at least two operators to cooperate, to complete the flange butt joint work;

[0004] Specifically, in the traditional crane pipe device, the outrigger is usually connected with the main part of the oil transfer arm through a rotary joint, but this connection mode does not consider how to effectively overcome the gravity moment generated by the outrigger. Therefore, in actual operation, the operator needs to manually adjust the position of the outrigger to ensure that it can be accurately connected with the flange of the tank truck, which not only wastes time and effort, but also has certain safety risks, because the operator may be accidentally injured during the adjustment of the outrigger;

[0005] Therefore, a new type of crane pipe device is needed to replace the traditional equipment to improve loading efficiency, reduce labor intensity and protect the safety of operators. CONTENT OF THE UTILITY MODEL

[0006] The utility model solves the technical problem in the prior art, and provides a damping system for crane pipe, which saves time and effort and maximizes the reduction of labor intensity of workers.

[0007] The technical problem solved by the utility model is solved through the following technical scheme, a damping system for crane pipe is installed between the outrigger of the oil transfer arm and the arm pipe flange, and comprises;

[0008] The support plate has one end as a support plate fixed end and the other end as a support plate hinged end, and the support plate fixed end is fixed on the rotary joint flange end face of the oil transfer arm;

[0009] The damping cylinder support has one end as a support fixed end and the other end as a support hinged end, and the support fixed end is fixed on the arm pipe flange end face of the oil transfer arm;

[0010] The damping cylinder is provided with a cylinder fixed end and a cylinder telescopic end, the cylinder fixed end is hinged to the support plate hinged end, and a damping cylinder joint is arranged on the cylinder telescopic end.

[0011] The technical problem solved by the damping system for the crane pipe can also be solved by the following technical scheme.

[0012] The technical problem solved by the damping system for the crane pipe can also be solved by the following technical scheme.

[0013] Compared with the prior art, the damping system for the crane pipe has the beneficial technical effects that: the damping system overcomes the gravity moment of the outrigger, so that the outrigger of the crane pipe can easily reach a horizontal position when being connected with the tank truck, without the need for manual labor to adjust, which greatly simplifies the connection process, so that one person can complete the connection work, improving the operation efficiency; in addition, the damping system not only improves the convenience of connection, but also enhances the overall stability of the crane pipe equipment, and through the telescoping of the damping cylinder, the crane pipe can maintain a stable posture during the connection process, avoiding safety hazards caused by shaking or tilting.
