Description

A locking device for the curtain door of a mine passenger tank

Technical field

The utility model belongs to the technical field of cage curtain door locking equipment, and is specifically a locking device for a mine cage curtain door.

Background technique

In the existing technology, cages used for hoisting mine shafts are the main lifting containers for lifting personnel. In order to ensure the safety of people riding in the cages, cage doors are installed on the cages. When the cages reach the bottom or mouth of the well, the cage doors need to be opened to facilitate the entry and exit of personnel. ;

At present, the main form of the cage door is the tank curtain. The cage curtain door is used as a protective packaging device for people riding in the tank. It lacks a closing and locking device for the cage curtain door, or when the cage is in place (well head or bottom), tank workers need to manually open the cage curtain door. The locking device increases the workload and intensity of tank workers in dangerous areas (the wellhead and bottom areas are high-altitude working areas), and poses safety risks.

Utility model content

In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a mine cage curtain door locking device, which solves the technical problems in the above background technology.

The solution adopted by the utility model is: a mine passenger tank cage curtain door locking device, which includes a tank curtain door track, a tank curtain door body, and a tank channel. The feature is that the tank curtain door track is slidingly connected to a tank curtain The door body, the tank curtain door running track is fixedly connected with an auxiliary base, the auxiliary base is hinged with a locking hook that matches the tank curtain door body, and one end of the locking hook is provided with a supporting wheel , There is a spring between the tank curtain door track and the locking hook body, and the tank track is provided with a convex curved rail that cooperates with the supporting wheel.

Preferably, the locking hook body is provided with two sets of first positioners corresponding to the auxiliary base at intervals, and the locking hook body is provided with a second positioner corresponding to the supporting wheel.

Preferably, the tank curtain door track and the tank curtain door body are made of stainless steel.

Preferably, the supporting wheel is made of rubber material.

Compared with the existing technology, through the cooperation of the locking hook body, the supporting wheel, the spring and the convex curved rail, the utility model can realize that the cage is located at the wellhead and the bottom of the well, and can automatically unlock the cage door body without manual operation. Unlock the locking device. When the cage is located between the wellhead and the bottom of the well, the locking hook cooperates with the tank curtain door body so that the tank curtain door body will not move along the tank curtain door track, ensuring the safety of personnel.

Detailed ways

The foregoing and other technical contents, features and effects of the present invention will be clearly presented in the following detailed description of the embodiment with reference to the accompanying drawings 1-4. The structural contents mentioned in the following embodiments are all referred to the accompanying drawings of the description.

Each exemplary embodiment of the present invention will be described below with reference to the accompanying drawings.

Embodiment 1 is a locking device for a mine cage curtain door, which includes a tank curtain door track 1, a tank curtain door body 2, and a tank channel 3. It is characterized in that the tank curtain door track 1 is slidingly connected to a tank curtain. Door body 2, the tank curtain door runway 1 is fixedly connected with an auxiliary base 4, and the auxiliary base 4 is hinged with a locking hook 5 that cooperates with the tank curtain door body 2, and the locking hook One end of the body 5 is provided with a supporting wheel 6, a spring 7 is provided between the tank curtain door track 1 and the locking hook body 5, and the tank channel 3 is provided with a convex curved rail 8 that cooperates with the supporting wheel 6 ; The locking hook body 5 is provided with two sets of first positioners 9 corresponding to the auxiliary base 4 at intervals, and the locking hook body 5 is provided with a second positioner 10 corresponding to the supporting wheel 6; The tank curtain door track 1 and the tank curtain door body 2 are made of stainless steel; the supporting wheel 6 is made of rubber material.

When in use, the tank cage and the tank curtain door track 1 are set up as one body. The lifting equipment allows the cage and the tank curtain door track 1 to move up and down in the well with people. The tank curtain door body 2 is slidably arranged along the tank curtain door track 1 and is installed at the wellhead. and the bottom of the well are provided with convex curved rails 8 respectively. When the cage and the tank curtain door runway 1 move to the wellhead or the bottom of the well, the supporting wheels 6 provided at the bottom of the tank curtain door runway 1 follow the convex curved rails 8 Sliding, the convex curved rail 8 is high in the middle and inclined on both sides. Therefore, when the supporting wheel 6 reaches the highest position of the convex curved rail 8, under the action of the locking hook 5, it overcomes the elastic force of the spring 7, causing the lock The fastening hook body 5 is separated from the tank curtain door body 2. Under the action of the lifting device, the tank curtain door body 2 is lifted upward along the tank curtain door track 1, and the tank curtain door body 2 is opened. People can go out from the cage. When the cage is located between the wellhead and the bottom of the well, the supporting wheel 6 does not contact the convex curved rail 8. Under the action of the return spring 7, the locking hook 5 cooperates with the tank curtain door body 2, so that the tank curtain door body 2 It cannot be lifted upward along the tank curtain door track 1 to ensure the safety of personnel when the tank cage is moving and has a good self-locking effect.

The above is only for illustrating the present utility model. It should be understood that the present utility model is not limited to the above embodiments, and various modifications that conform to the idea of the present utility model are within the protection scope of the present utility model.
