DETAILED DESCRIPTION

[0023] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0024] Additional aspects and advantages of the present invention will be further described below in conjunction with the accompanying drawings, and some will become apparent from the following description or be learned through practice of the present invention.

[0025] like Figures 1 to 4 As shown, a foundation pit safety protection device for construction includes a building fence 1, a plurality of fence fixing members 2 are provided at the bottom of the building fence 1, and the fence fixing member 2 includes a fixing cylinder 201 fixedly installed on the building fence 1, and a conical member 202 is fixedly installed at the bottom end of the fixing cylinder 201, and the conical member 202 is threadedly connected to the fixing cylinder 201, such as Figure 4 , Figure 6 and Figure 7As shown, a reinforcement component 3 is provided on the fixed cylinder 201, and the reinforcement component 3 includes a plurality of support rods 301 hingedly matched with the fixed cylinder 201, and a plurality of support rods 301 are fixedly provided with gears 302 at positions near the hinges with the fixed cylinder 201, and a column 303 is longitudinally slidably provided at the center of the fixed cylinder 201, and meshing grooves 304 are provided at positions of the columns 303 corresponding to the plurality of gears 302, and an inclined block 3041 for controlling the swing of the support rod 301 is fixedly provided inside the meshing groove 304, and the inclined surfaces of two adjacent inclined blocks 3041 face opposite directions. The depth of the meshing groove 304 is greater than the length of the meshing teeth of the gear 302. By utilizing the depth of the meshing groove 304 being greater than the length of the meshing teeth of the gear 302, when the column 303 deflects, the gear 302 will cause the support rod 301 to tilt to one side. When the other meshing groove 304 is matched with the meshing teeth of the other gear 302, the inclined surface of the inclined block 3041 inside the meshing groove 304 will cause the gear 302 to drive the support rod 301 to deflect back. At this time, the reciprocating swing of the support rod 301 and the conical surface of the support rod 301 can further improve the ground breaking effect (such as Figures 4 to 8 ), as shown Figure 4 , Figure 7 and Figure 8 As shown, the support rod 301 is hinged with the fixed cylinder 201 through the rotating shaft 305, and the support rod 301 and the gear 302 are both provided with movable holes 4 at positions corresponding to the rotating shaft 305, and the diameter of the movable hole 4 is larger than the diameter of the rotating shaft 305. By making the diameter of the movable hole 4 larger than the diameter of the rotating shaft 305, the gear 302 can cause the support rod 301 to tilt to one side.

[0026] like Figure 4 and Fig. 9 As shown, the fixed cylinder 201 is provided with receiving grooves 2011 at the positions corresponding to the multiple support rods 301, and two sealing gaskets 2012 are symmetrically provided at the openings of the receiving grooves 2011. The sealing gaskets 2012 are made of rubber. By using the provided sealing gaskets 2012, when the support rods 301 are extended, the sealing gaskets 2012 can quickly close the openings of the receiving grooves 2011 to prevent a large amount of soil from entering the fixed cylinder 201. Even if soil enters the fixed cylinder 201, the conical piece 202 can be removed to discharge the soil inside the fixed cylinder 201.

[0027] like Figures 1 to 4As shown, a screw rod 306 is rotatably provided at the top of the column 303, and the screw rod 306 is threadedly connected to the fixing tube 201. A through hole is provided at the position of the building fence 1 corresponding to the screw rod 306, and a conical surface is formed on the side of the support rod 301 away from the screw rod 306. The conical surface can improve the ground-breaking effect of the support rod 301 and further improve the installation efficiency. A rotation hole is provided at the end of the column 303 corresponding to the screw rod 306, and the screw rod 306 is connected to the rotation hole through a bearing. The bearing can reduce the friction force when the screw rod 306 rotates, improve the stability of the screw rod 306 when rotating, and allow the screw rod 306 to control the column 303 to move up and down.

[0028] The working process is as follows:

[0029] S1, such as Figures 1 to 4 As shown, when fixing the building fence 1, the conical member 202 can be used to facilitate the fixing tube 201 to penetrate into the soil, and the reinforcement process can be carried out at this time;

[0030] S2, such as Figures 3 to 6 As shown, when reinforcing the anchoring part of the building fence 1, the screw rod 306 is rotated to make the column 303 slide upward. At this time, the support rod 301 can be turned outward from the fixing tube 201 and anchored inside the soil by the cooperation between the meshing groove 304 and the gear 302;

[0031] S3, such as Figures 4 to 8 As shown, when the screw 306 rotates, since the depth of the meshing groove 304 is greater than the length of the meshing teeth of the gear 302, the column 303 will deflect a certain degree (the friction force at the rotational connection between the screw 306 and the column 303 can make the column 303 deflect a certain degree, and the degree of deflection depends on the relationship between the depth of the meshing groove 304 and the length of the meshing teeth of the gear 302. When the meshing groove 304 is matched with the gear 302, the column 303 will only slide longitudinally). When the column 303 deflects, the gear 302 will cause the support rod 301 to tilt to one side;

[0032] S4, such as Figures 4 to 8 As shown, when another meshing groove 304 is matched with the meshing teeth of another gear 302, the inclined surface of the inclined block 3041 inside the meshing groove 304 will cause the gear 302 to drive the support rod 301 to deflect back. At this time, the reciprocating swing of the support rod 301 and the conical surface of the support rod 301 can further improve the earth-breaking effect (when the meshing groove 304 is matched with the gear 302, when the column 303 slides longitudinally, the gear 302 drives the support rod 301 to swing back and forth by using the cooperation between the inclined blocks 3041 with staggered inclined surfaces and the meshing teeth of the gear 302);

[0033] S5, such as Figures 4 to 8As shown, the reciprocating swing of the support rod 301 can cause the soil to vibrate, so that when the support rod 301 is fully opened, the soil can tightly wrap the support rod 301, further improving the reinforcement effect and preventing the building fence 1 from tilting or being unstable after being anchored;

[0034] S6, such as Figures 3 to 8 As shown, during disassembly, the support rod 301 can be retracted by rotating the screw rod 306 in the opposite direction, and the reciprocating swing of the support rod 301 during retraction can increase the retraction speed.

[0035] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
