Figure 2 It is a front view of the whole of the first embodiment of the utility model. Figure 3It is a cross-sectional view of the moving structure of the first embodiment of the utility model.

[0023] The utility model provides a mine rock burst protection device: comprising a protection device body 101 and a support assembly, the support assembly comprising a plurality of mobile structures 102 and two rear support structures 103, the mobile structure 102 comprising a support tube 104, a hydraulic cylinder 105, a rotating member 106 and two auxiliary support members 107, the rear support structure 103 comprising a first cylinder 115 and a rear support member 116, the rotating member 106 comprising a connecting plate 108 and a universal wheel 109, the auxiliary support member 107 comprising a front support plate 110 and a plurality of front anti-skid teeth 111, the rear support member 116 comprising a support frame 112, a rear support plate 113 and a plurality of rear anti-skid teeth 114, the above-mentioned scheme solves the problem of the existing mine rock burst protection device, when the broken stone hits the left side of the protection device body 101, the mobile wheel in contact with the ground will rotate, thereby driving the entire device to move, thereby hitting the staff inside and causing a safety accident.

[0024] For this specific embodiment, the protective device body 101 is used to prevent the broken stones after the rock burst from hitting the workers from the top and sides, and to reduce the harm of the broken stones to the workers after the rock burst. The specific structure and usage of the protective device body 101 refer to the patent document with publication number CN219934816U, and will not be elaborated here.

[0025] Among them, the multiple mobile structures 102 are respectively located on one side of the protective device body 101; the support tube 104 is fixedly connected to the protective device body 101 and is located on one side of the protective device body 101; the hydraulic cylinder 105 is fixedly connected to the support tube 104 and is located inside the support tube 104; the rotating member 106 is arranged on one side of the hydraulic cylinder 105; two auxiliary support members 107 are respectively arranged on both sides of the support tube 104; the two rear support structures 103 are respectively located on the sides of the protective device body 101; the first cylinder 115 is fixedly connected to the protective device body 101 and is located on the side of the protective device body 101; the rear support member 116 is arranged on one side of the first cylinder 115. When the protective device body 101 is used, the protective device body 101 is moved by the rotating member 106. The protective device body 101 is moved to a suitable position, and then the hydraulic cylinder 105 in the support tube 104 is controlled to drive the rotating member 106 to retract into the support tube 104, so that the two auxiliary support members 107 are in contact with the ground, and then the two first cylinders 115 at the rear are controlled to drive the two rear support members 116 to contact the ground, thereby completing the auxiliary support for the entire device. When the gravel hits the protective device body 101, the rotating member 106 is retracted, and the auxiliary support member 107 and the rear support member 116 contact the ground to provide friction to prevent the protective device body 101 from moving, thereby solving the problem of the existing mine rock burst protective device that when the gravel hits the left side of the protective device body 101, the moving wheel in contact with the ground will rotate, thereby driving the entire device to move, thereby hitting the staff inside and causing a safety accident.

[0026] Secondly, the connecting disk 108 is fixedly connected to the output end of the hydraulic cylinder 105 and is located on one side of the hydraulic cylinder 105; the universal wheel 109 is arranged on one side of the connecting disk 108, and the connecting disk 108 is used to support the installation of the universal wheel 109. The universal wheel 109 is used to contact the ground and rotate when the position of the entire device needs to be moved, so that it is more convenient to move the entire device.

[0027] At the same time, the front support plate 110 is fixedly connected to the support tube 104 and is located on one side of the support tube 104; the multiple front anti-slip teeth 111 are respectively fixedly connected to the front support plate 110 and are respectively located on one side of the front support plate 110. After the universal wheel 109 is retracted into the support tube 104, the front support plate 110 contacts the ground and cooperates with the multiple front anti-slip teeth 111 to increase the friction force with the contact surface with the ground, and cooperates with the rear support member 116 to prevent the protective device body 101 from moving when hit by gravel.

[0028] In addition, the support frame 112 is fixedly connected to the output end of the first cylinder 115 and is located on one side of the first cylinder 115; the rear support plate 113 is fixedly connected to the support frame 112 and is located on one side of the support frame 112; the plurality of rear anti-slip teeth 114 are respectively fixedly connected to the rear support plate 113 and are respectively located on one side of the rear support plate 113. The support frame 112 is driven by the first cylinder 115 so that the rear support plate 113 contacts the ground and cooperates with the plurality of rear anti-slip teeth 114 and then with the front support plate 110, so that the protective device body 101 will not move when hit by gravel.

[0029] In the use of a mine rock burst protection device described in this embodiment, when the protection device body 101 is used, the protection device body 101 is moved to a suitable position by the universal wheel 109 on the connecting plate 108, and then the hydraulic cylinder 105 in the support tube 104 is controlled to drive the connecting plate 108 to drive the universal wheel 109 to retract into the support tube 104, so that the two front support plates 110 contact the ground and cooperate with the multiple front anti-slip teeth 111 to increase the friction force of the contact surface with the ground, and then the two first cylinders 115 at the rear are controlled to drive the two support frames 112 to drive the rear support plates 110 to contact the ground. The plurality of rear anti-skid teeth 114 increase the friction of the contact surface to complete the auxiliary support of the overall device. When the crushed stone hits the protective device body 101, the rotating member 106 is retracted. The front anti-skid teeth 111 and the rear anti-skid teeth 114 on the front support plate 110 and the rear support plate 113 contact the ground to provide friction to prevent the protective device body 101 from moving. This solves the problem of the existing mine rock burst protective device that when the crushed stone hits the left side of the protective device body 101, the moving wheel in contact with the ground rotates, thereby driving the overall device to move and hit the staff inside, causing a safety accident.

[0033] The fixing accessory 201 is disposed on one side of the rear support plate 113. When the entire device needs to be placed in one position for a long time, the fixing accessory 201 is operated to fix it to the ground, thereby increasing the placement stability of the entire device.

[0034] Secondly, the fixing plate 202 is fixedly connected to the rear support plate 113 and is located on one side of the rear support plate 113; the locking stud 203 is threadedly connected to the fixing plate 202 and is located on one side of the fixing plate 202. When the entire device needs to be placed in one position for a long time, a tool is used to operate the locking stud 203 on the fixing plate 202 to be threadedly connected to the ground, thereby increasing the placement stability of the entire device.

[0035] When using a mine rock burst protection device described in this embodiment, when the entire device needs to be placed in one position for a long time, a tool is used to operate the locking stud 203 on the fixing plate 202 to be threadedly connected with the ground, thereby increasing the placement stability of the entire device.
