For example, as shown in fig. 3, the direction C-D is a first direction, and the lifting mechanism 2 drives the link mechanism to perform lifting motion along the longitudinal direction; as shown in FIG. 2, the direction A-B is the second direction, and the sliding mechanism drives the lifting mechanism 2 to drive the link mechanism to move along the horizontal direction.
The number of the supporting members 1 may be plural, and is not particularly limited herein, and may be specifically set according to practical situations.
In particular, as shown in fig. 2, the number of the supporting components 1 in fig. 2 is preferably plural, and the plurality of supporting components 1 are divided into two rows, and the distance between two rows of supporting components 1 is 0.75m or 0.875m, and the distance between two adjacent supporting components 1 in each row is 1.2m.
The fully-mechanized coal mining face withdrawal sector supporting device provided by the embodiment, the supporting component 1 is used for actively supporting the fully-mechanized coal mining face, the connecting rod mechanism is connected with the supporting component 1, the lifting mechanism 2 can drive the connecting rod mechanism to move along the first direction, namely, the lifting mechanism 2 can drive the supporting component 1 to move along the first direction. As shown in fig. 3, the first direction is a vertical direction, and when the lifting mechanism 2 ascends, the supporting component 1 is driven to leave the ground, so that a certain distance is generated between the supporting component 1 and the ground; conversely, when the lifting mechanism 2 descends, the supporting component 1 is driven to move downwards, so that the distance between the supporting component 1 and the bottom surface is reduced. The lifting mechanism 2 is arranged on the sliding mechanism, and the sliding mechanism drives the lifting mechanism 2 to move along the second direction, so that the supporting component 1 is driven to slide along the second direction.
When the fully-mechanized coal mining face withdraws the support, the fully-mechanized coal mining face withdraws the fan-shaped area support device provided by the embodiment can move the support component 1 through the lifting mechanism 2 and the sliding mechanism, the support component 1 is not required to be carried manually, the labor intensity of workers is reduced, and the working efficiency is improved.
The fully mechanized mining face retraction sector supporting device provided by the embodiment further comprises a guide beam 3 and a pushing mechanism, wherein the pushing mechanism is used for pushing the guide beam 3 to move along the second direction, and the sliding mechanism is in sliding connection with the guide beam 3.

The sliding mechanism can drive the supporting component 1 to move along the length direction of the guide beam 3.
Specifically, as shown in fig. 2, when the sliding mechanism drives the support assembly 1 to move rightward along the length direction of the guide beam 3 by a certain distance, the sliding mechanism stops driving the support assembly 1 to move along the length direction of the guide beam 3, and at this time, the pushing mechanism pushes the guide beam 3 to move rightward by the same distance (i.e., the distance that the support assembly 1 moves rightward), so that the sliding mechanism drives the support assembly 1 to move on the guide beam 3 all the time. That is, the sliding mechanism is slidably connected with the guide beam 3, when the pushing mechanism pushes the guide beam 3 to move rightward, the guide beam 3 slides rightward relative to the sliding mechanism (at this time, the sliding mechanism does not move rightward along with the guide beam 3), and the sliding mechanism drives the support assembly 1 to move on the guide beam 3 all the time.
In a preferred implementation of the present embodiment, the linkage mechanism comprises a telescopic member 7, a steering arm 8 and a link 10. The steering arms 8 are hinged to the lifting mechanism 2, the steering arms 8 can rotate around the lifting mechanism 2, a clamp 9 is arranged at one end, deviating from the lifting mechanism 2, of each steering arm 8, a plurality of steering arms 8 are hinged to each steering arm 8, namely, each steering arm 8 is in rotary connection with the corresponding connecting rod 10, and then the connecting rods 10 on each steering arm 8 can rotate relative to the steering arms 8, and the adjacent connecting rods 10 are hinged.
The telescopic part 7 is connected with the lifting mechanism 2, one end of the telescopic part 7 deviating from the lifting mechanism 2 is connected with the connecting part of the adjacent connecting rod 10, and the telescopic part 7 stretches and stretches to drive the connecting rod 10 to rotate so as to drive the supporting component 1 to be close to or far away from the guide beam 3. The extension direction of the extension member 7 is the same as the length direction of the guide beam 3.
As shown in fig. 2, the lifting assembly is hinged with 4 steering arms 8, each steering arm 8 being rotatable about the axis of the lifting assembly. One end of each steering arm 8 is provided with a clamp 9, i.e. each steering arm 8 is connected with the corresponding support assembly 1 by the clamp 9, and the clamp 9 is detachably connected with the support assembly 1. In fig. 2, 4 steering arms 8 are hinged on the lifting assembly, and at most 4 steering arms 8 can be connected with 4 support assemblies 1. I.e. the lifting assembly can drive the 4 support assemblies 1 to rise or fall at the same time. Each steering arm 8 is hinged with a connecting rod 10, and every two adjacent connecting rods 10 are hinged. The telescopic part 7 is connected with the elevating system 2, and the one end that the telescopic part 7 deviates from elevating system 2 is connected with the junction of two adjacent connecting rods 10 in the left side in fig. 2, and when the telescopic part 7 during operation, the telescopic end of telescopic part 7 stretches out, and the distance between the junction of two adjacent connecting rods 10 in the left side in fig. 2 and the junction of two adjacent connecting rods 10 in the right side increases for every steering arm 8 all swings to the direction that is close to guiding beam 3, thereby every steering arm 8 swings and drives corresponding supporting component 1 to the direction that is close to guiding beam 3.
Specifically, as shown in fig. 2, the number of the joints of the links 10 adjacent in the longitudinal direction of the guide beam 3 is 2, and they are referred to as a first link joint and a second link joint, respectively. When the telescopic end of the telescopic piece 7 stretches out leftwards, the telescopic piece 7 can push the first connecting rod connecting position leftwards, at this moment, the distance between the first connecting rod connecting position and the second connecting rod connecting position is increased, and at this moment, each connecting rod 10 drives the corresponding steering arm 8 to swing towards the side of the guide beam 3, the steering arm 8 and the support assembly 1 are clamped with each other through the clamping device 9, namely, the telescopic piece 7 can drive the support assembly 1 to draw close towards the side of the guide beam 3. When the telescopic end of the telescopic piece 7 is retracted rightward, the distance between the connecting position of the first connecting rod and the connecting position of the second connecting rod is reduced, and each connecting rod 10 drives the corresponding steering arm 8 to swing to the side far away from the guide beam 3, namely the telescopic piece 7 can drive the supporting component 1 to move to the side far away from the guide beam 3.
For convenience of description, in fig. 2, the support assemblies 1 of the upper row are in order from left to right: the first support assembly, the second support assembly, the third support assembly, the fourth support assembly, the fifth support assembly, the sixth support assembly and the seventh support assembly; the following rows of support assemblies 1 are arranged in sequence from left to right: eighth, ninth, tenth, eleventh, twelfth, thirteenth and fourteenth support assemblies.

When the support assembly 1 is moved, the first support assembly, the second support assembly, the eighth support assembly and the ninth support assembly are folded by the connecting rod mechanism, the lifting mechanism 2 drives the first support assembly, the second support assembly, the eighth support assembly and the ninth support assembly to lift, the sliding mechanism can drive the first support assembly, the second support assembly, the eighth support assembly and the ninth support assembly to move rightwards between the two rows of support assemblies 1 along the length direction of the guide beam 3, and the movement is stopped when the seventh support assembly and the fourteenth support assembly are moved. The pushing mechanism pushes the guide beam 3 to move rightwards, and when one end of the guide beam 3, which is propped against the pushing mechanism, moves between the third supporting component and the tenth supporting component, the movement is stopped, and one end of the guide beam 3, which is away from the pushing mechanism, is positioned on the right side of the seventh supporting component (the side, which is away from the sixth supporting component, of the first supporting component). The sliding mechanism drives the first supporting component, the second supporting component, the eighth supporting component and the ninth supporting component to continuously move rightwards along the length direction of the guide beam 3, and when the first supporting component moves to the right side of the seventh supporting component and the eighth supporting component moves to the right side of the fourteenth supporting component, the sliding mechanism stops moving.
