[0002] After searching, Chinese patent number CN202320833277.7 discloses a temporary support device for coal mine excavation, comprising two groups of base plates and fixed sleeves fixed on the front and rear sides of the upper surface of the base plates, and the fixed sleeves are slidably inserted with sliding rods on the front and back sides. The temporary support device for coal mine excavation is used in conjunction with the grooved plates, lifting columns, slots and teeth, so that when adjusting the support height of the device, the adjusting bolts can be loosened, and the two groups of grooved plates move away from each other under the action of the springs, and then the use height of the lifting column is adjusted, the adjusting bolts are tightened, and the teeth are embedded in the slots to fix the lifting column, so that multiple groups of teeth are embedded in the slots, and the contact area between the lifting column and the grooved plates is large. The lifting column and the grooved plates can be regarded as a whole column, which further enhances the bearing pressure of the device, improves the protection performance of the device, and ensures the safety of coal mine construction.

[0003] The above patent utilizes a lifting column to connect with a trough plate to form a column, which is used to improve the load-bearing effect of the overall equipment and improve the protective performance. However, there are still the following deficiencies in actual use: during construction in a coal mine, the environment is relatively dark, so a large amount of lights are required to ensure the lighting environment during construction. The above patent support equipment is not equipped with lighting equipment. At the same time, a certain amount of dust is generated during construction. If it is not intercepted, a large amount of dust will appear at the entrance of the coal mine, causing obstruction of the workers' vision and affecting the workers' own safety. For this reason, we propose a coal mine excavation construction support device. Utility Model Content

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention;

[0022] Reference Figure 1-4 A coal mine excavation construction support device includes two legs 1, a horizontal plate 2 is fixedly connected between the two legs 1, the top of the two legs 1 is movably connected to a roof plate 6, a telescopic rod is arranged between the roof plate 6 and the two legs 1, an arch frame 8 is fixedly installed on the top of the roof plate 6, the arch frame 8 is used to support the edge of the coal mine hole, and lighting components 7 are arranged on both sides of the roof plate 6; a mounting groove 3 is fixedly installed on one side of the top of the horizontal plate 2, and a liftable partition net 5 is arranged in the mounting groove 3, and the top of the partition net 5 is connected to the bottom side of the roof plate 6 through a clamping component.

[0023] The interior of the mounting groove 3 is rotatably connected to a winding roller 14 , the middle portion of the winding roller 14 is intertwined with the end portion of the partition net 5 , and the clamping component includes a hanging ear 12 and a hook 13 . There are two hanging ears 12 , which are evenly installed on both sides of the top of the partition net 5 .

[0024] There are two hooks 13, and the two hooks 13 are fixed on both sides of the bottom of the top plate 6. The two hooks 13 are connected to the two hanging ears 12. As the top plate 6 rises and falls, the partition net 5 is pulled up and down. Because the hooks 13 and the hanging ears 12 are connected to each other, that is, in the later stage, as the top plate 6 moves, the partition net 5 can be driven to move synchronously, thereby increasing the overall protection range.

[0025] The lighting assembly 7 includes a mounting base 16 fixed on the top plate 6 , and side plates 15 are fixedly connected to both ends of the mounting base 16 , and a light rod 19 is rotatably connected between the two side plates 15 .

[0026] 5. A coal mine excavation construction support device according to claim 4 is characterized in that a plurality of sleeves 17 are fixedly installed in the middle of the light rod 19, and the ends of the plurality of sleeves 17 are fixedly connected with lighting lamps 20. A motor 18 is fixedly installed on the outer side of one side panel 15, and the output end of the motor 18 passes through the side panel 15 and is interconnected with the end of the light rod 19. The lighting lamp 20 further enhances the lighting effect in the entire mine cave. At the same time, the motor 18 can drive the light rod 9 and the plurality of lighting lamps 20 to adjust the angle, which is conducive to lighting treatment at different positions in the coal mine cave.

[0027] A group of cylinders 4 are fixedly installed in the middle of the bottom end of the horizontal plate 2. The output end of the cylinder 4 passes through the horizontal plate 2 and is connected to a push rod 11. A lifting plate 10 is fixedly installed on the top of the push rod 11. The top of the lifting plate 10 is connected to the bottom of the top plate 6. After starting the cylinder 4, the cylinder 4 drives the push rod 11 and the lifting plate 10 to move up and down. Since the top plate 6 and the two groups of legs 1 are separate (connected by telescopic rods), the top plate 6 can move up and down with the thrust, and can achieve different changes according to the different heights of the coal mine cave, and is used for the arch frame 8 to support the mine cave.

[0028] A plurality of reinforcing ribs 9 are provided on the top of the top plate 6, and the plurality of reinforcing ribs 9 are crisscrossed, and the plurality of reinforcing ribs 9 are located in the middle of the arch frame 8, and the top ends of the reinforcing ribs 9 are connected to the inner bottom ends of the arch frame 8. By providing a plurality of crisscrossed reinforcing ribs 9 to support the overall compressive strength of the arch frame 8, the overall stability is further guaranteed.

[0029] Move the entire equipment to the required construction support location, start the cylinder 4 according to the support height, first drive the arch frame 8 to rise and fall, when the top wall of the arch frame 8 contacts the coal mine entrance, the support treatment can be achieved, because the arch frame 8 is fixed on the top plate 6, as the top plate 6 moves, it drives the partition 5 to move (because the partition 5 and the top plate 6 are connected by the hanging ear 12 and the hook 13), so the partition 5 will change with the rising and falling position of the top plate 6, which is beneficial to intercept dust in the later stage.
