Description

Technical Field

[0001] This application relates to the technical field of shaft cages, and particularly to a maintenance movable platform for shaft cages. Background Art

[0002] A cage is a commonly used lifting container in a shaft. It can be used to transport ore, waste rock, personnel, materials, equipment, etc. The cage can be used for both main shaft hoisting and auxiliary shaft hoisting, and is a widely used hoisting method in small mines. The cage mainly consists of a tank body, a connecting device, a guiding device, etc. Common cage types include single-layer cages and multi-layer cages, among which single-layer cages are the most widely used in mines. The hoisting operation of the cage is usually completed by a friction hoist. The cage carrying ore cars or materials is hoisted along the shaft to a designated position on the ground or underground. During the hoisting process, the cage is guided through the guide rail to eliminate lateral swing and distortion, ensuring the safety and stability of hoisting.

[0003] The shaft is usually hundreds of meters deep. Each time when maintaining skip buckets and cages in the shaft, a temporary maintenance platform needs to be built, and the temporary maintenance platform also needs to be removed after the maintenance. However, during the process of building and removing the temporary maintenance platform, there is an easy risk of personnel falling into the shaft. Utility Model Content

[0008] A load-carrying component, one end of which is rotatably connected to the bottom of the bracket, and the other end is connected to the traction mechanism;

[0009] Wherein, there are two groups of traction mechanisms and load-carrying components respectively. When the traction mechanism operates, it drives the load-carrying component to rotate around the rotation axis, so that the load-carrying component is horizontal or vertical.

[0033] Embodiment 1:

[0034] See Figure 1 and Figure 2 , a maintenance movable platform for a shaft cage. The maintenance movable platform for the shaft cage includes:

[0035] A bracket 1, on which a traction mechanism 2 is provided;

[0036] A load-carrying assembly 3, one end of which is rotatably connected to the bottom of the bracket 1, and the other end is connected to the traction mechanism 2;

[0037] Among them, there are two sets of the traction mechanism 2 and the load-carrying assembly 3 respectively. When the traction mechanism 2 operates, it drives the load-carrying assembly 3 to rotate around the rotation axis so that the load-carrying assembly 3 is horizontal or vertical.

[0038] Specifically, the traction mechanism 2 is used to drive the load-carrying assembly 3. The load-carrying assembly 3 is used to carry maintenance personnel and maintenance tools. Two sets of load-carrying assemblies 3 are provided to increase the load-carrying area and the size of the load-carrying space. Four head ropes 12 are provided at the upper end of the cage 11, and three tail ropes 13 are provided at the lower end. The cage 11 is connected to the friction hoist through the head ropes 12 and the tail ropes 13. The friction hoist can drive the cage 11 to move up and down in the shaft to facilitate it to reach the height of the load-carrying assembly 3.

[0039] See Figure 1 , when the maintenance operation has not started, the load-carrying assembly 3 is in a vertically retracted state. At this time, the lower end of the load-carrying assembly 3 is rotatably connected to the bottom of the support 1, and the upper end is connected to the traction mechanism 2. Through the support of the traction mechanism 2, the load-carrying assembly 3 always maintains a vertical state, so as to avoid affecting the normal operation of the skip and the cage 11.

[0040] See Figure 2 , when carrying out the maintenance operation, start the traction mechanism 2. Through the traction of the traction mechanism 2, the load-carrying assembly 3 rotates counterclockwise around the rotation axis. When the load-carrying assembly 3 is lowered to the horizontal state, the traction mechanism 2 stops operating. At this time, the maintenance personnel stand on the load-carrying assembly 3 to perform maintenance on the cage 11. After the maintenance operation is completed, the load-carrying assembly 3 is rotated clockwise through the traction mechanism 2 to restore it to the vertical state. At this time, the load-carrying assembly 3 is retracted into the support 1.

[0041] In this embodiment, the support 1, the traction mechanism 2 and the load-carrying assembly 3 together constitute a maintenance activity platform. During the maintenance operation, the activity platform can be lowered onto the steel beam on the side of the shaft. Personnel stand on the activity platform to perform maintenance operations. After the maintenance is completed, the activity platform is retracted and fixed firmly, without affecting the normal operation of the skip and the cage 11, thus avoiding the safety risk of personnel falling into the shaft caused by building and dismantling the temporary maintenance platform.

[0042] In addition, the maintenance activity platform of the present application can also avoid the time-consuming and laborious problems caused by building and dismantling the temporary maintenance platform.

[0043] Embodiment Two:

[0044] See Figures 3 to 4 , based on Embodiment One, optionally, the traction mechanism 2 includes a handwheel drum 4 fixed to the outside of the support 1 and a roller 5 installed at the upper end of the support 1;

[0045] Among them, a pulling rope 6 is wound around the handwheel drum 4.

[0046] Specifically, a cross plate for installing the handwheel drum 4 is provided on the outside of the support 1. The handwheel drum 4 is fixed to the cross plate, and the roller 5 is fixed to the top of the support 1. The handwheel drum 4 and the roller 5 are connected through the pulling rope 6.

[0047] Optionally, the load component 3 includes:

[0048] A load board 7 provided inside the bracket 1, one end of the load board 7 is rotatably connected to the bottom of the bracket 1, and a fixed pulley 8 is installed at the other end.

[0049] Specifically, the height of the load board 7 is greater than the height of the bracket 1, and the load board 7 is rotatably connected to the bottom of the bracket 1. In this way, by rotating the load board 7 to a horizontal state, it can have the functions of carrying people and loads.

[0050] Optionally, the end of the pulling rope 6 far from the handwheel drum 4 is sequentially slidably connected to the roller 5 and the fixed pulley 8, and then fixed to the bracket 1.

[0051] Specifically, by rotating the handwheel drum 4, the pulling rope 6 can be actuated. Under the action of friction, the roller 5 and the fixed pulley 8 rotate synchronously. When carrying out maintenance operations, release the fixation of the pulling rope 6 to the bracket 1, and then rotate the handwheel drum 4 to actuate the pulling rope 6, the load board 7 is released, and the load board 7 rotates counterclockwise until it is horizontal. After the maintenance operation is completed, rotate the handwheel drum 4 to actuate the pulling rope 6, the load board 7 is pulled up to a vertical state, and then the pulling rope 6 is fixed.

[0052] See Figure 4 , optionally, one end of the load board 7 is rotatably connected to the bottom of the bracket 1 through a rotating shaft 9.

[0053] See Figure 3 , optionally, the end of the pulling rope 6 far from the handwheel drum 4 is fixed to the bracket 1 through a rope buckle 10.

[0054] It should be noted that the structures and / or installation methods not detailed in this application can be known to those skilled in the art in combination with common general knowledge and / or existing technologies, and are not the key points of disclosure in this application, so no further elaboration will be made here.

[0055] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of this application and not to limit them. Although this application has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of this application; the dimensions of the drawings have nothing to do with the specific physical objects, and the physical object dimensions can be arbitrarily changed.
