Embodiment Construction

[0021] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0022] Such as Figure 1-2 As shown, a kind of self-locking adjustable opening size clamp provided by the present invention comprises a frame 13, a linear bidirectional drive mechanism, a right splint 4, a left splint 5 and a guide shaft 2, wherein the frame 13 is provided with a guide shaft 2. The left splint 5 and the right splint 4 are slidingly connected with the guide shaft 2. The linear bidirectional drive mechanism is arranged on the frame 13 and connected with the right splint 4 and the left splint 5. The linear bidirectional drive mechanism is used to drive the right splint 4 and the left splint. Splint 5 moves in reverse.

[0023] The inner sides of the clamping ends of the left clamping plate 5 and the right clamping plate 4 are respec...

Abstract

The invention belongs to the technical field of petroleum drilling and exploitation and particularly relates to a self-locking type clamp capable of adjusting the size of an opening. The self-lockingtype clamp comprises a rack, a linear bidirectional driving mechanism, a right clamping plate, a left clamping plate and a guide shaft. The guide shaft is arranged on the rack, the left clamping plateand the right clamping plate are connected with the guide shaft in a sliding mode, the linear bidirectional driving mechanism is arranged on the rack and connected with the right clamping plate and the left clamping plate, and the linear bidirectional driving mechanism is used for driving the right clamping plate and the left clamping plate to move oppositely. By means of the self-locking type clamp capable of adjusting the size of the opening, drill pipe grabbing in well drilling can be safer, and the clamp can tightly clamp a drill pipe to avoid loosing and falling of the drill pipe even accidental situations occur; and besides, the size of the opening can be adjusted freely within the clamping range, and the clamp can adapt to drill pipes of all diameters within the largest opening range.

Description

technical field [0001] The invention belongs to the technical field of oil drilling, in particular to a self-locking clamp with adjustable opening size. Background technique [0002] Oil drilling operation is a project with huge investment and certain risks. The quality of the equipment directly affects the drilling safety and economic benefits. The two-story platform robot is a new type of equipment with the characteristics of high efficiency and labor saving. As the end effector of the robot on the second floor, the tongs play the role of grabbing the drill pipe. The operation safety requires that the tongs must ensure that the drill pipe cannot fall off when moving the drill pipe. Traditional tongs mostly use hydraulic cylinder direct drive to clamp the drill pipe. After clamping, the clamping state is maintained by continuously supplying cylinder pressure or using a balance valve to lock the pressure. This type has the following two disadvantages: First, the mechanical ...
