Embodiment Construction
[0021] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0022] The innovation point of the present invention is to use a set of power input and through a specially designed coupling device to complete two very important and relatively independent movement processes of the automatic catwalk in the pipe string processing system.
[0023] refer to figure 1 , the working principle of the present invention is,
[0024] When the cart is fixedly connected to the chain at point A, with the rotation of the driving sprocket, the entire catwalk cart can move in the -K or K direction; when part B is fixedly connected to the chain, object B can be realized Move in the direction of -P or P, and thus realize the two movement states of the catwalk through a set of power system.
[0025] refer to figure 2 , the structure of the present invention is,
[0026] A track is provided on the bracket assembly 1, a la...

The invention discloses a chain gear-shifting hanging device for an automatic catwalk. The chain gear-shifting hanging device comprises a bracket assembly, wherein a railway is arranged on the bracket assembly; a big pulley assembly is arranged on the railway; a chain driving mechanism is fixedly arranged on the big pulley assembly; the upper chain section of the chain driving mechanism is in clutch connection with a small vehicle chain hanging mechanism; simultaneously, the small vehicle chain hanging mechanism is fixedly connected with a utility cart assembly; the lower chain section of the chain driving mechanism is in clutch connection with a large vehicle chain hanging mechanism; the large vehicle chain hanging mechanism is fixedly connected with the bracket assembly. According to the device disclosed by the invention, the same chain transmission system is used; the chain gear-shifting hanging device is quick and accurate in hanging, is simple in structure, high in equipment utilization rate and convenient to maintain; the processing capacity of the catwalk is ensured; the weight of equipment is lightened; two actions of sliding a large vehicle and pushing a small vehicle of the automatic catwalk are completed.
Description
technical field [0001] The invention belongs to the technical field of petroleum equipment, is used for a rail-type automatic catwalk in a pipe column processing system, and relates to a chain shifting and engaging device for an automatic catwalk. Background technique [0002] Under normal working conditions, the main functions of the automated catwalk are two: one is to transport the pipe string that has been placed on the catwalk to the wellhead; the other is to retract the pipe string from the wellhead to the catwalk. In the actual operation process, the coordinated actions of multiple mechanisms are required to complete these two main functions. However, as an automated catwalk, the most important function is the delivery process of the pipe string. Pushing the pipe column is completed for the overall sliding transportation of the cart and the sliding of the trolley on the cart slideway. [0003] For the need to complete the sliding movement of the cart and trolley, it ...
