Problems solved by technology

[0002] In the process of oil drilling, the automatic transportation of the pipe string between the ground pipe rack and the drilling workbench generally adopts a power catwalk machine. Several pairs of safety pin mechanisms need to be installed symmetrically on both sides of the frame. Hydraulic systems are commonly used at home and abroad to control the work of safety pins. The number of hydraulic cylinders is large, the cost is high, and there are many procedures. The safety of column transportation cannot be guaranteed, so the present invention provides a new safety device to solve the above problems

Embodiment Construction

[0011] The present invention will be further described and introduced below in conjunction with the accompanying drawings.

[0012] refer to figure 1 , figure 2 , the power catwalk conveyor frame uses a double-hinged safety pin mechanism, and the power catwalk conveyor frame uses a double-joint safety pin mechanism 9 three groups to form a whole body, and the two power catwalk conveyor frames of each group use double hinges The safety pin mechanism 9 is installed on the delivery frame 8 both sides, and every group of power catwalk machine delivery frame is spaced apart along the length direction of the delivery frame with a certain distance between the double-hinged safety pin mechanism 9 . The entire device has a simple and reliable structure, low cost, high safety and stability during the transportation of the pipe string 10 , simplifies the transportation procedure of the pipe string 10 , and improves the transportation efficiency of the pipe string 10 .

Abstract

The utility model discloses a bi-articulated safety pin mechanism for a power catwalk machine transmission rack, which mainly comprises a safety pin, an upper connecting block, a transmission rod, a lower connecting block, a base lifting pin, a tension spring, a pin shaft, an upper cylinder sleeve, a lower cylinder sleeve and the like. When the transmission rack is on the ground, since the base lifting pin under the bi-articulated safety pin mechanism is pressed, the safety pin is collected into the working surface of the transmission rack so as to allow a tubular column to be transversely sent into and sent out of the V-shaped slot of the transmission rack conveniently, and when the transmission rack leaves the ground, the safety pin is popped out under the effect of the spring, so as to play the effect of preventing the tubular column from rolling out of the transmission rack transversely during a transporting process. The bi-articulated safety pin mechanism provided by the invention is mainly used for ensuring transport safety of the tubular column for petroleum drilling, the entire structure of the mechanism is simple and reliable, the manufacturing cost is low, safety and reliability are high, tubular column transportation procedures are simplified, and the safety and the efficiency of tubular column transport are improved.

Description

technical field [0001] The invention relates to a double-hinged safety pin mechanism for a conveying frame of a power catwalk machine, which is mainly used to ensure the safety of pipe strings in the up and down transportation during oil drilling, and belongs to the technical field of oil drilling safety. Background technique [0002] In the process of oil drilling, the automatic transportation of the pipe string between the ground pipe rack and the drilling workbench generally adopts a power catwalk machine. Several pairs of safety pin mechanisms need to be installed symmetrically on both sides of the frame. Hydraulic systems are commonly used at home and abroad to control the work of safety pins. The number of hydraulic cylinders is large, the cost is high, and there are many procedures. The safety of column transportation cannot be guaranteed, so the present invention provides a new safety device to solve the above problems. Contents of the invention [0003] Aiming at...
