[0002] In coal mine production, after the comprehensive mining face (mining face) is completed, the hydraulic supports and other equipment of the comprehensive mining face (mining face) need to be withdrawn. A triangular area to be supported will be formed between the support to be withdrawn and the end of the working face, usually referred to as the triangle area. During the removal of the hydraulic support, this triangle area will cyclically appear and need cyclic support. The triangle area is a high-risk area for accidents when withdrawing the support.

DETAILED DESCRIPTION

[0030] The utility model is described in further detail below.

[0031] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. The following embodiments are used to illustrate the utility model but are not used to limit the scope of the utility model.

[0032] like Fig. 9 As shown, for the convenience of subsequent structural description, this application defines that the three-dimensional space where the triangular area support equipment is located has three orthogonal directions, namely vertical, horizontal and longitudinal. The vertical direction from the tunnel roof to the ground is the vertical direction (up and down direction), the left and right movement direction of the support equipment is the horizontal direction (left and right direction), and the other horizontal direction perpendicular to the movement direction of the support equipment is the longitudinal direction (front and back direction).

[0033] See also Figure 1 This embodiment provides a new type of triangular area support equipment, including a first support device 1 and a second support device 2, and the lower end bearing mechanisms 102 of the first support device 1 and the second support device 2 are connected by a retractable frame moving device 3.

[0034] Combination Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, the first supporting device 1 and the second supporting device 2 can independently perform their own lifting and lowering actions, and the walking action of the first supporting device 1 and the second supporting device 2 is realized by the extension and retraction of the moving frame device 3; through the intermittent rotation cooperation between the two, the triangle area support equipment can continuously support the tunnel roof while also realizing the movement function in the direction of withdrawing the support.

[0035] The first supporting device 1 includes a lifting mechanism 101, a bearing mechanism 102 and a supporting mechanism 103 respectively connected to the bottom and top of the lifting mechanism 101; a four-link mechanism 104 and a shielding mechanism 105 respectively connected to the bearing mechanism 102 and the supporting mechanism 103; a side supporting mechanism 106 and a side telescopic mechanism 107 respectively connected to the left and right sides of the supporting mechanism 103; a frame adjustment mechanism 108 installed inside the bearing mechanism 102 and capable of extending forward horizontally; and a bottom lifting mechanism 109 installed on the left side of the bearing mechanism 102 and capable of extending downward vertically (the bottom lifting mechanism 109 is installed close to the uphill side, and the bottom lifting mechanism 109 can be installed on both the left and right sides of the bearing mechanism 102 to increase the scope of application of the present supporting device).

[0036] The length of the lifting mechanism 101 can be extended or shortened, and its telescopic direction is vertical and can have a certain inclination angle. It is a multi-stage telescopic hydraulic cylinder; the bearing mechanism 102 is in direct contact with the ground to support the supporting equipment. There is no special regulation for its shape, and it can be all structural forms with supporting and fixing functions; the supporting mechanism 103 is used to support the roof of the coal roadway in the triangular area. It is a box structure, and the lower part is connected to the lifting mechanism 101 and the four-bar mechanism 104; the lower end of the lifting mechanism 101 is fixed to the bearing mechanism 102, which plays a fixing role, and the upper end is the telescopic end, which is connected to the supporting mechanism 103. When the lifting mechanism 101 performs a telescopic movement, it can push the supporting mechanism 103 to move up and down, thereby supporting or removing the coal roadway roof.

[0037] Two sets of four-bar linkages 104 are box-shaped and are located on both sides of the lifting mechanism 101. Their upper ends are hinged to the supporting mechanism 103, and their lower ends are hinged to the bearing mechanism 102. They are used to bear the horizontal and torsional forces of the top plate, play a certain supporting and cutting role, and improve the stability of the support.

[0038] The bottom lifting mechanism 109 can be extended or shortened, and can perform vertical telescopic movement. It is preferably a hydraulic cylinder. When the first supporting device 1 moves in the direction of withdrawing the bracket and encounters an uphill slope, the bottom lifting mechanism 109 extends to touch the ground, lifting the left side of the first supporting device 1 to enable it to go uphill smoothly.

[0039] The side support mechanism 106 is arranged on the left side of the support mechanism 103, and the side telescopic mechanism 107 is installed on the right side of the support mechanism 103, which can be retracted into the support mechanism 103 and can be horizontally moved to the right side. Figure 8 The comb tooth structure shown has strong rigidity.

[0040] The first side support mechanism 106 includes a first side support support assembly 106a and a first side support telescopic assembly 106b. The first side support support assembly 106a is a box structure, hinged to the left side of the support mechanism 103. The two ends of the first side support telescopic assembly 106b are respectively hinged to the side of the support mechanism 103 and the lower end of the first side support support assembly 106a, and can be extended or shortened. The first side support telescopic assembly 106b is a hydraulic cylinder in this embodiment. When the first side support telescopic assembly 106b is extended or shortened, it pulls the first side support support assembly 106a to rotate around the hinge point to adjust the support angle of the first side support mechanism 106, which is used to support the empty top area between the supports to be withdrawn, and can also provide support when collapse occurs here, thereby protecting the support device from being buried.

[0041] Combination Figure 4 , Figure 5 As shown, the shielding mechanism 105 is hinged to the rear side of the supporting mechanism 103, and the shielding mechanism 105 includes a shielding support component 105a and a shielding telescopic component 105b, wherein the shielding support component 105a is a box structure, and the shielding telescopic component 105b can be extended or shortened. In this embodiment, it is a hydraulic cylinder that can perform telescopic movement. The two ends of the shielding telescopic component 105b are respectively hinged to the shielding support component 105a and the bearing mechanism 102 to form an effective protection space. When the shielding telescopic component 105b performs telescopic movement, the shielding support component 105a is pulled to rotate around the hinge point. The shielding mechanism 105 is arranged at the rear of the supporting equipment, which can make the supporting equipment more stable, and can provide support at the collapsed part at the rear to protect the supporting equipment from being buried.

[0042] The frame adjustment mechanism 108 can be extended or shortened. In this embodiment, it is a hydraulic cylinder. The two frame adjustment mechanisms 108 are respectively arranged inside the front side of the carrying mechanism 102. When the distance between the supporting equipment and the front equipment is not appropriate, the frame adjustment mechanism 108 is used to adjust the distance between the supporting equipment and the front equipment. The direction of the supporting equipment when moving can also be adjusted.

[0043] The second supporting device 2 has a substantially similar structure to the first supporting device 1, except that the second side telescopic structure and the second side supporting structure are opposite in direction to the first side telescopic structure and the first side supporting structure.

[0044] The bottom lifting mechanism 209 can be extended or shortened, and can perform vertical telescopic movement. It is preferably a hydraulic cylinder. When the second supporting device 2 moves in the direction of withdrawing the bracket and encounters an uphill slope, the bottom lifting mechanism 209 extends to touch the ground, lifting the left side of the second supporting device 2 to enable it to go uphill smoothly.

[0045] When this embodiment is used specifically:

[0046] Combination Figure 6 As shown, there is a predetermined distance between the first support device 1 and the second support device 2, and there is a certain distance between the triangular area support equipment and the support to be withdrawn. At this time, the first support device 1, the first side support mechanism 106, the second support device 2 and the second side support mechanism 206 are propped up to support the coal plate in this area; after the first hydraulic support on the left (support No. 6) is withdrawn from the area, the first support device 1 maintains the supporting state, the second support device 2 is lowered, and the frame moving device 3 is extended to push the second support device 2 to move to the right, and the second support device 2 moves to the left. After a certain distance, the distance between it and the first supporting device 1 is continuously increased. At this time, the first side telescopic mechanism 107 and the second side telescopic mechanism 207 are simultaneously extended to timely support the new middle space formed. After the second supporting device 2 reaches the predetermined position, the second supporting device 2 is raised, and the first supporting device 1 is lowered. The moving frame device 3 is retracted to make it pull the first supporting device 1 to move to the right. At the same time, the first side telescopic mechanism 107 and the second side telescopic mechanism 207 are retracted. After the first supporting device 1 reaches the predetermined position, the first supporting device 1 is raised. Figure 7 The state shown in this way is repeated repeatedly by alternately lifting and moving the first supporting device 1 and the second supporting device 2, ensuring that the triangular area support equipment can move while continuing to support the top plate of the area, filling the empty top area after the hydraulic support is withdrawn, avoiding the need for manual intervention and reducing operational risks.
