Detailed Description

The technical scheme of the utility model is explained in detail in the following with the attached drawings:

referring to fig. 1, a protective device for a cave entrance in building engineering comprises a main frame made of pipes. The pipe comprises four horizontally arranged sleeves 1, and the four sleeves 1 are arranged in parallel up and down. The pipe further comprises four vertically arranged connecting rods 2, and the connecting rods 2 are arranged in parallel left and right. The sleeve 1 and the connecting rod 2 are mutually crossed and connected to form a main frame similar to a Chinese character 'jing'.

Furthermore, the lower ends of the four connecting rods 2 extend out of the sleeve 1 at the lowest part to be used as a supporting foot of the whole device.

The left end of each sleeve 1 is respectively provided with a screw rod 3 matched with the internal thread on the sleeve 1. The screw 3 can be extended and retracted with respect to the sleeve 1 when rotated.

Considering that the difficulty of directly processing the internal thread in the inner hole of the sleeve 1 is large, the threaded hole of the nut is connected and matched with the screw rod 3 in the embodiment. Specifically, as shown in fig. 2, the first nuts 7 are firstly sleeved on the screw rod 3, the mutual distances and angles of the first nuts 7 are determined, records and marks are made, then the first nuts 7 are dismounted from the screw rod 3, the first nuts 7 are welded in the inner hole of the sleeve 1 from inside to outside, and the mutual distances and angles are ensured to be consistent with those of the first nuts during welding, so that the screw rod 3 can be accurately matched with the first nuts 7 in sequence after penetrating.

Furthermore, the outer end of the screw rod 3 is provided with a sharp cone part 10 which can be embedded into a wall body to increase fastening force.

Furthermore, in order to prevent the screw rod 3 from loosening, a second nut 8 positioned outside the sleeve 1 is sleeved on the screw rod 3. For the convenience of operation, the second nut 8 is provided with an operating handle 9.

As shown in fig. 1 and 3, a top rod 4 is inserted into the other end of the sleeve 1, a locking hole is further formed in the side wall of the other end of the sleeve 1, a through hole is formed in the top rod 4, the locking hole and the through hole are arranged in the left-right direction, and the distance between the locking hole and the through hole is equal.

The other end of the sleeve 1 is also provided with a bolt 11, and the bolt 11 sequentially penetrates through the locking hole and the through hole to fix the sleeve 1 and the ejector rod 4 together. The ram 4 can be rapidly retracted and positioned relative to the sleeve 1.

Preferably, the locking hole and the through hole are both arranged vertically, and a horizontally bent bending part is arranged at the upper end of the bolt 11. The plug 11 is inserted from the upper side and is not easy to fall off.

Further, a protective screen 5 (steel wire mesh) is further installed in the region, which can pass through, of the main frame.

Furthermore, a sign 6 is further installed on the main frame, the sign 6 can be powered on, and prompt words such as 'please note' are displayed through a customized lamp.

In this embodiment, an opening is formed in the middle of the protection net 5, and the indication board 6 is disposed at the opening.

During installation, the device is vertically placed at the opening, and the left end of the screw rod 3 is close to the left side wall at the moment. Then pull out bolt 11, pull out ejector pin 4, make its outer end be close to the right side wall, make the locking hole and through-hole position corresponding simultaneously, then insert bolt 11, fixed ejector pin 4. Then, the screw 3 is rotated to extend the screw 3 from the sleeve 1 until the screw 3 and the rod 4 are in contact with the wall on the corresponding side and the tapered portion 10 of the screw 3 is embedded in the wall. Finally, the second nut 8 is rotated to be in close contact with the end of the sleeve 1, and the screw rod 3 is locked to prevent loosening.

When the device is disassembled, the second nut 8 is firstly loosened, and the screw rod 3 is rotated, so that the whole device can be removed from the hole. Then the bolt 11 is pulled out, the mandril 4 is inserted into the sleeve 1 and then is fixed by the bolt 11, the size of the whole device is reduced, and the carrying is convenient.
