DETAILED DESCRIPTION

[0028] 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.

[0029] See also Figure 1 - Figure 6 As shown, the utility model is a foundation pit slope detection device, comprising a base plate 1, a tube body 3 is fixedly installed on the upper surface of the base plate 1 through a clamp 2, a telescopic joint 4 is arranged at one end of the tube body 3, the telescopic joint 4 is installed inside the tube body 3 through a fixing assembly 5, a support frame 101 is arranged on the upper surface of the base plate 1, a connecting shaft 6 is rotatably connected inside the support frame 101, one end of the connecting shaft 6 passes through the support frame 101 and is installed with a rotating handle 7, a rotating drum 8 is installed on the outer surface of the connecting shaft 6, a guide seat 301 is arranged on the outer surface of the tube body 3, a guide assembly 9 is arranged on the outer surface of the telescopic joint 4, a pulley seat 10 is arranged on the end of the telescopic joint 4 away from the tube body 3, a pulley 11 is rotatably connected inside the pulley seat 10, a wire rope 12 is wound around the outer surface of the rotating drum 8, one end of the wire rope 12 passes through the guide seat 301 and the guide assembly 9 in sequence and abuts against the outer surface of the pulley 11, a scale line is arranged on the outer surface of the wire rope 12, and a plumb bob 13 is installed on the end of the wire rope 12 away from the rotating drum 8;

[0030] When testing the slope of the foundation pit, first place the bottom plate 1 on the upper surface of the top of the slope, the end of the pulley 11 away from the telescopic joint 4 is located in the same vertical plane as the boundary line of the top of the slope and the side slope, the bottom end of the plumb bob 13 is in contact with the boundary line of the top of the slope and the side slope, and the length of the line rope 12 in the vertical direction and the plumb bob 13 is recorded, and then the telescopic joint 4 extending from the side slope is rotated counterclockwise to rotate the rotating handle 7 so that the rotating handle 7 drives the connecting shaft 6 and the rotating drum 8 to rotate, so that the line rope 12 wound outside the rotating drum 8 is released, so that the bottom end of the plumb bob 13 is in contact with the side slope, and finally the slope of the side slope is calculated based on the length of the telescopic joint 4 and the vertical height of the side slope obtained through the line rope 12, and then it is determined whether the slope of the side slope meets the construction requirements;

[0031] The guide assembly 9 includes a base 901, which is mounted on the outer surface of the telescopic joint 4. One end of the base 901 is hinged to a limit block 902. The outer surface of the limit block 902 is provided with a first magnetic block 903. The outer surface of the base 901 is provided with a second magnetic block 904. The first magnetic block 903 is magnetically connected to the second magnetic block 904.

[0032] When the telescopic joint 4 needs to be adjusted, the limit block 902 is pushed outward to cancel the magnetic connection between the first magnetic block 903 and the second magnetic block 904, and the limit block 902 is axially rotated around the hinge axis with the base 901. When the limit block 902 cancels the fixation of the wire rope 12, the wire rope 12 can be removed from the base 901, so that the telescopic joint 4 can be adjusted;

[0033] A level detector 14 is installed on the upper surface of the support frame 101;

[0034] The fixing assembly 5 includes a connecting column 501, a mounting groove 401 is provided at one end of the telescopic joint 4, the connecting column 501 is installed inside the mounting groove 401, a threaded hole is provided in the middle of the connecting column 501, a screw rod 502 is threadedly connected inside the threaded hole, a baffle 503 is provided on the upper surface of the screw rod 502, an extrusion column 504 is provided on the lower surface of the screw rod 502, an expansion piece 505 is abutted against the inner surface of the tube body 3, and an extrusion column 504 is provided inside the expansion piece 505;

[0035] When the length of the telescopic section 4 needs to be adjusted, the telescopic section 4 is rotated so that the telescopic section 4 drives the connecting column 501 to rotate. When the connecting column 501 rotates, the screw 502 can move upward or downward along the axial direction. When the screw 502 moves downward, the squeezing column 504 pushes the expansion piece 505 to expand outward, so that the expansion piece 505 expands and fits tightly against the inner surface of the tube body 3, so that the tube body 3 and the telescopic section 4 have a better locking effect, avoiding the extension of the telescopic section 4 from the inside of the tube body 3 due to external influences during use. By rotating the telescopic section 4 in the opposite direction, the squeezing column 504 cancels the squeezing of the expansion piece 505, and then the expansion piece 505 cancels the squeezing of the tube body 3, the telescopic section 4 can be adjusted to telescope, thereby achieving the effect of the length of the telescopic section 4;

[0036] The outer surface of the expansion member 505 is provided with anti-slip textures;

[0037] The anti-slip grooves on the outer surface of the expansion member 505 can increase the friction between the expansion member 505 and the inner surface of the tube body 3, thereby preventing the expansion member 505 from being displaced, thereby fixing and locking the telescopic joint 4 and the tube body 3;

[0038] The outer surface of the baffle 503 is provided with a mounting hole, one end of which passes through the baffle 503, the screw rod 502 and the extrusion column 504 in sequence and extends downward, and a limit assembly 15 is provided inside the mounting hole;

[0039] The limiting assembly 15 includes a connecting rod 1501, which is installed inside the mounting hole. A first limiting plate 1502 is provided on the upper surface of the connecting rod 1501, and a second limiting plate 1503 is provided on the lower surface of the connecting rod 1501. The outer surface of the first limiting plate 1502 abuts against the outer surface of the baffle 503, and the outer surface of the second limiting plate 1503 abuts against the outer surface of the expansion member 505.

[0040] When the telescopic joint 4 moves toward the inside of the tube body 3, the telescopic joint 4 pushes the connecting column 501 to move, and at the same time, the outer surface of the first limit plate 1502 abuts against the outer surface of the baffle 503, which allows the expansion piece 505 to move toward the inside of the tube body 3 at the same time. When the telescopic joint 4 moves toward the outside of the tube body 3, the telescopic joint 4 pulls the connecting column 501 to move, and at the same time, the outer surface of the second limit plate 1503 abuts against the outer surface of the expansion piece 505, which allows the expansion piece 505 to move toward the outside of the tube body 3 at the same time.
