[0029] The utility model provides a temporary support device for coal mining tunnels, including a plurality of protective supports 101, a carrier plate 102 and two fixing mechanisms, wherein the fixing mechanisms include a plurality of fixing rods 109, a screw rod 110, a connecting plate 111 and a plurality of limiting members, wherein the limiting members include a limiting sheet 115 and a limiting rod 116. The above-mentioned scheme solves the technical problem that the protective supports 101 are fixed by bolts, and the disassembly and assembly process of the bolts is relatively troublesome, thereby making it inconvenient to quickly disassemble and assemble the protective supports 101.

[0030] According to this specific embodiment, the end surface of the carrier plate 102 has a plurality of square grooves 103, both sides of the carrier plate 102 have thread grooves 104 and a plurality of fixing grooves 105, and the fixing grooves 105 pass through the square grooves 103, two roller mechanisms 106 are provided at both ends of the carrier plate 102, a plurality of hydraulic jacks 107 are provided below the carrier plate 102, and a support plate 108 is provided at the output end of the plurality of hydraulic jacks 107, and the plurality of protective brackets 101 are respectively inserted into the carrier plate 102. The support plate 108 is connected to the support plate 102 and is located in the corresponding square groove 103. By arranging the hydraulic jack 107 and the support plate 108 below the carrier plate 102 and arranging the roller mechanism 106 at both ends of the carrier plate 102, it is not only capable of performing support work, but also capable of retracting the support plate 108 through the hydraulic jack 107 to push the roller mechanism 106 downward, thereby jacking up the device for easy displacement through the roller mechanism, and being able to quickly protect dangerous places, thereby improving the convenience of use.

[0031] The two fixing mechanisms are symmetrically arranged on both sides of the carrier plate 102, the screw rod 110 is provided with a rotating ring 112, one end of the screw rod 110 is provided with a rotating disk 113, the middle part of the connecting plate 111 has a rotating groove 114, and the plurality of fixing rods 109 are respectively fixedly connected to the connecting plate 111 and are located on the end surface of the connecting plate 111. The plurality of fixing rods 109 are also respectively plugged into the carrier plate 102 and are located in the corresponding fixing grooves 105 and penetrate the corresponding protective bracket 101. The screw rod 110 is rotatably connected to the connecting plate 111 and penetrates the connecting plate 111. The two end surfaces of the connecting plate 111, and the rotating ring 112 is located in the rotating groove 114, the screw rod 110 is also threadedly connected to the carrier plate 102 and is located in the corresponding thread groove 104, the connecting plate 111 is arranged on one side of the carrier plate 102, and through the arrangement of multiple fixing rods 109 and the connecting plate 111, multiple protective brackets 101 can be fixed at the same time, thereby achieving a quick disassembly and assembly of the protective bracket 101, and at the same time, the screw rod 110 is used to fix the connecting plate 111, thereby improving the fixing effect of the fixing rod 109 on the protective bracket 101.

[0032] Secondly, the two sides of the carrier 102 also have a plurality of limit cavities 117, and the plurality of limit cavities 117 are symmetrically arranged on both sides of the fixing groove 105, the limit plate 115 is fixedly connected to the limit rod 116 and is located at one end of the limit rod 116, the limit rod 116 is fixedly connected to the connecting plate 111 and is located at one end of the connecting plate 111, the limit rod 116 is also slidably connected to the carrier 102, and the limit rod 116 and the limit plate 115 are both located in the corresponding limit cavity 117, and the setting of the limit plate 115 and the limit rod 116 can prevent the connecting plate 111 from falling off from one side of the carrier 102.

[0033] Again, a handle 118 is disposed on the end surface of the rotating disk 113 , and an anti-slip cover 119 is disposed on the handle 118 . The anti-slip cover 119 can improve the gripping force of the handle 118 , thereby facilitating the rotation of the rotating disk 113 through the handle 118 .

[0034] When the protective bracket 101 is disassembled by using the utility model, the rotating disk 113 is rotated counterclockwise to drive the screw 110 to move out of the thread groove 104. At this time, the plurality of fixing rods 109 are simultaneously moved out of the corresponding fixing grooves 105 under the action of the connecting plate 111. At this time, the protective bracket 101 to be disassembled can be pulled out from the corresponding two square grooves 103. When it is necessary to install, the protective bracket 101 is placed in the corresponding two square grooves 103, and then the protective bracket 101 is rotated clockwise to move out of the corresponding two square grooves 103. The rotating disk 113 causes the screw rod 110 to rotate into the threaded groove 104 and drives the connecting plate 111 to move. Under the action of the connecting plate 111, the plurality of fixing rods 109 are inserted into the corresponding fixing grooves 105 and penetrate the protective bracket 101, thereby completing the installation. This method can improve the efficiency of disassembly and assembly of the protective bracket 101, and solves the technical problem that the protective bracket 101 is fixed by bolts, and the disassembly and assembly process of the bolts is relatively cumbersome, making it inconvenient to quickly disassemble and assemble the protective bracket 101.
