The guard device is arranged in batches on both sides of the inner wall of the hole, and then the steel pipe is placed on the top of the bottom plate on both sides, and then the wooden board is set up to bend and sink to block the hole. With this protection method, after construction is completed, it is at the same height as the top of the hole. Compared with the traditional hole protection of setting up guardrails, this device can achieve good protection without affecting the relevant construction activities of personnel in this part.

[0005] Furthermore, side panels are fixedly installed on both sides of the top of the bottom plate, and a screw is installed on the outer side of any side plate through a threaded connection, which is convenient for fixing the steel pipes placed on the top of the two bottom plates.

[0006] Furthermore, a knob is fixedly mounted on the end of the screw away from the side plate, and the surface of the knob is provided with an anti-slip pattern.

[0007] Furthermore, stabilizing frames are fixedly installed on both sides of the bottom end of the base plate, and the shape of the stabilizing frames is triangular, which increases the load-bearing strength of the base plate.

[0008] Furthermore, a connection hole is opened through one side of the receiving plate. After the steel pipe is erected, the receiving plate and the inner wall of the hole can be fixed through the connection hole and fasteners, thereby increasing the stability and strength after the installation.

[0009] Furthermore, a rubber sleeve is fixedly installed on the outer side of the slider, and the outer surface of the rubber sleeve fits tightly with the inner wall of the slide groove, which can increase the damping during the sliding adjustment between the receiving plate and the top plate, making it easier to fix after adjustment.

[0010] The technical effects and advantages of this utility model are:

[0011] The utility model adopts this design to arrange the protective devices in batches on both sides of the inner wall of the hole, then place the steel pipes on the top of the bottom plates on both sides, and then set up wooden boards, so as to bend and sink to block and protect the hole. With this protection method, after the construction is completed, it is at the same height as the top of the hole. Compared with the traditional hole protection of setting up protective railings, this device can achieve good protection without affecting the personnel carrying out related construction activities in this part.

[0012] The utility model adopts this design so that the steel pipe is placed between the two side plates on the top of the bottom plate, and the bolt is rotated so that the bolt is located on the top of the steel pipe, thereby firmly restraining the steel pipe. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The technical solution of the present invention will be described clearly and completely below with reference to the accompanying drawings of the present invention.

[0019] Example 1: Reference Figure 1-4The utility model provides a horizontal hole protection device, including: a protection device 100, the protection device 100 includes a receiving plate 110, the top of the receiving plate 110 is provided with a top plate 111, the bottom of the receiving plate 110 is provided with a bottom plate 112, the receiving plate 110, the top plate 111 and the bottom plate 112 form a Z-shaped member, the top of the top plate 111 is provided with a fixing hole 117, the top of the receiving plate 110 is fixedly installed with a slider 118, and the top of the top plate 111 is provided with a sliding groove 120. The slider 118 is slidably installed inside the slide groove 120. The top of the slider 118 is fixedly installed with an abutment block 119. The bottom end of the abutment block 119 fits with the top of the top plate 111. Stabilizing frames 113 are fixedly installed on both sides of the bottom end of the bottom plate 112. The shape of the stabilizing frames 113 is triangular. A connecting hole 116 is opened on one side of the receiving plate 110. A rubber sleeve 121 is fixedly installed on the outside of the slider 118. The outer surface of the rubber sleeve 121 fits tightly against the inner wall of the slide groove 120.

[0020] The working principle of the first embodiment of the present invention is as follows: when in use, the receiving plate 110 is fitted against the inner wall of the hole, and the top plate 111 is fitted against the plane around the top of the hole, and the top plate 111 is fitted against the ground of the hole through fasteners and fixing holes 117, and the above steps are repeated to arrange the protective devices 100 equidistantly on both sides of the inner wall of the hole, and then the steel pipes and other components are placed on the top of the bottom plate 112 after arrangement on both sides. Since the receiving plate 110 and the top plate 111 are connected by sliding, even if there is a certain horizontal error between the receiving plates 110 on both sides, it can be calibrated after sliding adjustment, and then a wooden board is laid on top of the steel pipe. After laying, the wooden board is flush with the top of the hole, and the protection of the hole is completed. Example
