Description

Technical Field

[0001] The utility model belongs to the technical field of vertical shaft cage guides, in particular to a positionable vertical shaft cage guide device. Background Art

[0002] A vertical shaft cage is a rectangular iron cage primarily used for vertical shaft hoisting operations in mines. Capable of carrying ore, coal, waste rock, personnel, materials, and equipment, the cage is a crucial tool for vertical transportation in mines, specifically serving as a mine elevator. The cage guide device is a crucial component of the mine hoisting system, guiding the cage's correct movement within the shaft and preventing it from deflecting or colliding, thereby ensuring the safety and stability of the hoisting operation.

[0003] The utility model patent with patent application publication number 202420352042.0 discloses a single-rope cage in a vertical shaft, including a cage body, an upper guide rail welded on the upper surface of the cage body, and a through groove on the surface of the upper guide rail. An electric push-pull cage opening mechanism is formed by arranging a lower guide rail, a plastic folding door, an upper guide rail, a motor, a bidirectional screw, a moving block, and a threaded sleeve. By starting the motor, the output end of the motor drives the bidirectional screw to rotate, and then the two plastic folding doors at the opening of the cage body move along the through groove of the upper guide rail through the moving block, so that the threaded sleeves on the two moving blocks move away from each other along the surface of the bidirectional screw, and the sliding column at the bottom of the plastic folding door slides along the sliding groove opened in the lower guide rail, so that the wavy structure of the two plastic folding doors folds and contracts, thereby realizing the rapid opening of the cage body. Compared with the existing cage curtain door structure, since there is no gap between the plastic folding doors, the pinching phenomenon caused by the opening and closing of the cage curtain door is avoided.

[0004] According to the above patent, there is a vertical shaft cage that still has shortcomings in actual use. The most obvious one is that although the current cage is equipped with protective devices such as anti-fall devices and overwinding protection devices, it may be affected by environmental factors in the mine (such as humidity, temperature, dust, etc.), causing the device to malfunction. It is urgent to set up a secondary manual locking device to ensure the safety of the cage shaft and prevent the cage from accidentally falling or moving. For this reason, we propose a locatable vertical shaft cage guide device. Utility Model Content

[0005] The purpose of the utility model is to provide a positionable vertical shaft cage guide device to solve the problems raised in the above background technology.

[0006] In order to achieve the above-mentioned purpose of the invention, the present invention provides the following technical solutions:

[0007] The present application is specifically as follows: a positionable vertical shaft cage guide device, comprising: a shaft and a cage body, the cage body being slidably disposed in the shaft cavity, both side walls of the shaft being provided with I-shaped guide plates, and the side walls of two sets of the I-shaped guide plates being fixedly connected to tooth plates;

[0008] The cage body is provided with a guide member for guiding the cage body, and both sides of the inner cavity of the cage body are fixedly connected with a U-shaped frame, and the inner side wall of the U-shaped frame is provided with a connecting groove, and the inner cavity of the connecting groove is rotatably connected with a bidirectional screw, and the outer side walls of the bidirectional screw are threadedly connected with threaded blocks at both ends, and the side walls of the threaded block are fixedly connected with a rack, and the rack is used in conjunction with the tooth plate. A driving member for driving the bidirectional screw to rotate is provided on the U-shaped frame.

[0009] As a preferred technical solution of the present application, the guide member includes two groups of mounting grooves, which are opened on both side walls of the cage body. Rollers are fixedly provided on the inner side walls of the mounting grooves, and the rollers are used in conjunction with the I-shaped guide plate.

[0010] As a preferred technical solution of the present application, one side wall of the U-shaped frame is fixedly connected to a mounting box, and the inner side wall of the mounting box is rotatably connected to a connecting rod, which passes through the side wall of the U-shaped frame and is fixedly connected to the bidirectional screw.

[0011] As a preferred technical solution of the present application, the driving member includes a worm wheel and a worm, the worm is rotatably connected to the inner cavity of the mounting box, the worm wheel is fixedly connected to the outer side wall of the connecting rod, and the worm wheel and worm are meshingly arranged.

[0012] As a preferred technical solution of the present application, the side wall of the installation box is rotatably connected to a turntable, and the turntable is fixedly connected to the worm.

[0013] As a preferred technical solution of the present application, the I-shaped guide plate is located in the inner cavity of the mounting groove.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] In the scheme of this application:

[0016] 1. By setting a driving member to drive the bidirectional screw to rotate, the bidirectional screw drives the two sets of threaded blocks to slide relative to each other in the connecting groove, and the threaded blocks drive the racks to move relative to each other, and the two sets of racks clamp and engage the tooth plates, thereby playing the role of secondary manual locking, ensuring the safety of the cage shaft and preventing the cage from accidentally falling or moving.

[0017] 2. The worm is driven to rotate in the installation box through the turntable, and the worm drives the worm wheel and the connecting rod to rotate, and the bidirectional screw is driven to rotate through the connecting rod. Since the worm gear transmission has a large transmission ratio range, high-speed transmission can be achieved. At the same time, due to the friction and sliding of the meshing surface, the worm gear transmission has a good load capacity, which makes the rotation of the bidirectional screw self-locking, thereby improving the working efficiency of the cage guide device.
