Embodiment 1

[0026] refer to figure 1 and figure 2 , which is the first embodiment of the present invention, this embodiment provides a novel triangular area support device, the novel triangular area support device includes the first novel triangular area support unit 100 of the present invention (referred to as the first support unit) And the second new triangular support unit 200 of the present invention (abbreviated as the second support unit), the second support unit 200 is arranged on the front end of the first support unit 100, the first support unit 100 and the second support unit The units 200 can carry out their own jacking and walking actions, and through the intermittent rotation and cooperation between the two, the triangular area support device can move forward under the premise of continuously jacking up the coal mine roof.

[0027] In order to facilitate the subsequent structural description, the present invention defines that the three-dimensional space where the triangul...

Embodiment 2

[0033] refer to figure 2~7, is the second embodiment of the present invention, which differs from the first embodiment in that it also includes a telescopic plate 202a, top side braces (106, 206), horizontal telescopic parts 203a and lateral telescopic parts (103a , 203b). In the last embodiment, the novel triangular support device comprises a first support unit 100 and a second support unit 200; the second support unit 200 is arranged on the front end of the first support unit 100, and the first support unit 100 and the second support unit 200 can carry out their respective jacking and walking actions, and through the intermittent rotation between the two, the support device in the triangular area can move forward under the premise of continuously jacking up the coal mine roof function.

[0034] Only one of the first support unit 100 and the second support unit 200 may be provided, and the second support unit 200 is located directly in front of the first support unit 100 ....

Embodiment 3

[0044] refer to Figures 8a-8c , is the third embodiment of the present invention, which is different from the first two embodiments in that: the second support unit 200 can be provided with one or more groups, when it is provided with two or more second support units 200 , are arranged vertically side by side with the first support unit 100, and except for the second support unit 200 adjacent to the first support unit 100, the horizontal telescopic members 203a of the other second support units 200 are all aligned with the latter first support unit 200 The base parts 203 of the two supporting units 200 are connected.

[0045] When the second support unit 200 is provided with two groups and ≥ 2 groups, the first support unit 100 and the plurality of second support units 200 alternately advance the first support unit 100 and the plurality of second support units 200 The control method of falling, advancing and jacking up in turn is as follows:

[0046] It is defined as that i...

Abstract

The invention discloses a novel triangular area supporting unit. The novel triangular area supporting unit comprises vertically-arranged vertical telescopic parts, top supporting parts, basic parts and side supporting parts, wherein the top supporting parts and the basic parts are connected to the top end and the bottom end of the vertical telescopic parts correspondingly, the side supporting parts are connected to the top supporting parts, the side supporting parts are connected to the basic parts through a four-connecting-rod mechanism, the two ends of two vertical connecting rods of the four-connecting-rod mechanism are hinged to the side supporting parts and the basic parts correspondingly, and horizontal telescopic parts are arranged inside the basic parts. According to the novel triangular area supporting unit, a supporting mode that the top supporting parts and the side supporting parts are combined is arranged, the supporting strength is improved, the top side supporting parts are used for supporting the side face of a coal mine, safety is higher, and a telescopic plate capable of stretching and retracting front and back ends simultaneously is adopted, so that the supporting area is larger.

Description

[0001] This application is a divisional application of a Chinese invention patent application. The filing date of the original application: April 27, 2020; the application number: 202010343720.3; the name of the invention: a new triangular area support device. technical field [0002] The invention relates to the technical field of coal mine fully mechanized mining, in particular to a triangular area support unit of a fully mechanized mining face. Background technique [0003] In coal mine production, after the mining of the fully mechanized mining face (recovery working face) is completed, it is necessary to withdraw the equipment such as the hydraulic support of the fully mechanized mining face. A triangular area requiring circular support will be formed between them, and this area is an accident-prone location for retracting supports. At present, one or more methods among single hydraulic props, I-beams (hinged top beams), wooden stacks, and cover brackets are generally u...
