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 method (without elevator) is often used in domestic casing running operations, which cannot fully meet the construction requirements

Embodiment Construction
[0015] A device for remotely controlling pneumatic elevators and chucks, including a chuck control cylinder 1 and an elevator control cylinder 2 for respectively controlling the chuck reversing valve and the reversing work of the elevator reversing valve, the chuck controlling cylinder, and the elevator The control cylinder is respectively connected with the vertically installed first and second gas switches 4 and 5 installed in the remote control box 3, and the first and second gas switches are both connected with the third gas switch 6 installed horizontally. Control the air intake of the first and second air switches. This method can ensure that when the air intake of one air switch installed vertically is working, 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 accidental operation. Operation improves safety; install thrust sensor 7 and elevator control box 8 on the elevator; said installed thrust s...

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 device for remotely controlling pneumatic elevators and chucks. Background technique [0002] At present, elevators and chucks are generally required to be used in casing casing construction in domestic and foreign petroleum mines. 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. There are many factors. As a result, single-chuck methods (without elevators) are often used in domestic casing running operations, which cannot fully meet the construction requirements. [0003] Using the remote control method, the pneumatic elevator and chuck can be controlled on the drilling floor, without special personnel opera...
