Problems solved by technology
The elevators / chucks are manually controlled beside the machine. Since the working position of the elevators is at high altitude, the operation of the elevators needs to be carried out by a special person standing at high altitude, and the drilling team must also be equipped with a casing uprighting platform, which is inconvenient and unsafe for operation and control. many factors
As a result, single-chuck methods (without elevators) are often used in domestic casing operations, which cannot fully meet the construction requirements

Embodiment Construction
[0015] A remote control pneumatic elevator / chuck, comprising a chuck control cylinder 1, an elevator control cylinder 2, a chuck control cylinder, and an elevator control cylinder that respectively control the chuck reversing valve and the elevator reversing valve. They are respectively connected to the first and second gas switches 4 and 5 installed vertically in the remote control box 3. Both the first and second gas switches are connected to the third gas switch 6 installed horizontally. The third gas switch controls the 1. The air intake of the second air switch. This method can ensure that when one air switch is installed vertically, the other air switch is cut off and cannot work, so that the elevator and the chuck cannot work at the same time to prevent misoperation. Improve safety; install thrust sensor 7 and elevator control box 8 on the elevator; the thrust sensor is fixed on the elevator shield, including the rotating bracket fixed on the elevator shield 10 through th...

The invention discloses a remote-control pneumatic elevator / chuck which comprises a chuck control air cylinder and an elevator control air cylinder. The chuck control air cylinder and the elevator control air cylinder are connected with a first air switch and a second air switch of a remote-control box respectively, the first air switch and the second air switch are both connected with a third air switch, air incoming of the first air switch and the second air switch is controlled by the third air switch, and a thrust sensor and an elevator control box are mounted on the elevator. The remote-control pneumatic elevator / chuck is reasonable in structure, centralized control on the action process of the elevator and the chuck is realized through the remote-control box, and wireless signals between the remote-control box and the elevator control box are established to enable automatic alarming of descending positions of the elevator to be realized, so that remote control on the complete working process of the elevator and chuck is realized.
Description
Technical field [0001] The invention relates to a remote control pneumatic elevator / chuck. Background technique [0002] At present, elevators and chucks are generally required to be used in the construction of casing drilling in domestic and foreign oil fields. Elevators / chucks are controlled manually by the machine. Because the elevators work at high altitudes, the elevator operations must be carried out at high altitudes, and the drilling crew must be equipped with casing centralizers, which is inconvenient and unsafe. There are many factors. As a result, the single chuck method (without elevator) is often used in domestic casing running operations, which cannot fully meet the construction requirements. [0003] Using remote control mode, pneumatic elevators and chucks can be controlled on the drill floor, without the need for special personnel to operate at high altitude, which is convenient for operation and eliminates unsafe factors. The use of elevators and chucks at the ...
