DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-3A coal mine support structure with an early warning function includes a top support assembly 1 and an oil top 4. The top support assembly 1 includes two hollow plates 101. A movable plate 102 is movably arranged inside the hollow plate 101. A connecting plate 103 is fixedly arranged on one side opposite to the two movable plates 102. A hinge seat 2 is fixedly arranged at the bottom of the hollow plate 101. A support rod 3 is fixedly arranged at the output end of the oil top 4. The other end of the support rod 3 is hinged to the hinge seat 2. A cross bar 5 is welded on one side opposite to the two support rods 3.

[0022] It should be noted that before the equipment is sent into the tunnel, the support rod 3 is folded at the bottom of the top support assembly 1, which is convenient for transportation. After it is sent to the installation position, it is unfolded until the top support assembly 1 and the support rod 3 are vertical, and then the height of the top support assembly 1 is adjusted by the oil top 4. After the adjustment is completed, the cross bar 5 is welded to the opposite side of the two support rods 3.

[0023] In this embodiment, a telescopic rod 6 and a height adjustment assembly 11 are fixedly provided on the top of the cross bar 5. The tops of the telescopic rod 6 and the height adjustment assembly 11 are fixedly connected to the warning agent release assembly. The warning agent release assembly includes a storage bottle and a dye 10 stored in the storage bottle. The storage bottle is composed of a cylindrical glass tube 7 and a hemispherical trigger head 8. The diameter of the trigger head 8 is larger than the diameter of the vertical section of the glass tube 7. The top of the trigger head 8 is in contact with the bottom of the top support assembly 1, and an annular groove 9 is provided at the joint between the glass tube 7 and the trigger head 8.

[0024] It is particularly noted that the dye 10 is a yellow dye, which is more eye-catching in a dim alley and has a better warning effect for nearby personnel.

[0025] In this embodiment, the telescopic rod 6 includes an outer tube 61 fixed to the top of the cross bar 5 and an inner rod 62 fixed to the bottom of the glass tube 7, one end of the inner rod 62 extends to the inside of the outer tube 61, and the height adjustment component 11 includes a bearing 111, a threaded barrel 112, a threaded rod 113 and a docking rod 114, wherein the bearing 111 is fixedly arranged on the top of the cross bar 5, the threaded barrel 112 is rotatably arranged on the top of the bearing 111, the threaded rod 113 is threadedly connected to the inside of the threaded barrel 112, and the docking rod 114 is fixedly arranged on the top of the threaded rod 113, one end of which passes through the top of the threaded barrel 112 and is fixedly connected to the glass tube 7.

[0026] To sum up, the coal mine support structure with early warning function is provided with an early warning agent release component. When the top support component 1 is squeezed and deformed, the trigger head 8 breaks from the glass tube 7, and the dye in the glass tube 7 and the trigger head 8 spills out and spreads on the ground. When the staff inspects, the dye on the ground can be used to find the abnormality in the first time, and the workers can also find the abnormality when passing by, which can have a certain degree of early warning effect; by providing a height adjustment component 11, after the cross bar 5 is welded to the support rod 3, the glass tube 7 is held still and the threaded cylinder 112 is rotated to adjust the height of the glass tube 7 and the trigger head 8 until the top of the trigger head 8 contacts the bottom of the top support component 1, so that it is convenient to modify the existing support parts.
