Description

Technical Field

[0001] The invention relates to the technical field of foundation pit monitoring, in particular to a prism bracket for a total station. Background Art

[0002] The subway is a fast, high-capacity, electrically-driven rail transit system built in the city. The subway runs on a fully enclosed line. During the construction of the subway, it is necessary to set up monitoring points in the deep foundation pit to monitor the inside of the deep foundation pit. Existing monitoring devices usually use total stations. During detection, the prism lens reflects the detection signal emitted by the total station with a large distance between the prisms. The total station obtains signals such as the distance to the measurement area, and feeds the signal back to its own software system for processing. The relevant data is then displayed through the total station display interface.

[0003] Existing prisms are generally fixed in the monitoring area by a bracket. The prism needs to be aligned with the direction of the total station and then fixed. The angle of the prism will inevitably deviate during fixation. After fixation, the angle of the prism cannot be adjusted quickly, resulting in low detection efficiency. Summary of the invention

[0004] The technical problem to be solved by the present invention is the problem that the existing prism bracket is fixedly installed and inconvenient to adjust.

[0005] In order to solve the above problem, the present invention provides a prism bracket capable of quickly adjusting the angle and height of the prism, and the specific solution is: A total station prism bracket comprises a fixed base plate, a telescopic assembly and a rotating seat. A plurality of horizontal adjustment assemblies are arranged on the fixed base plate. The bottom of the horizontal adjustment assembly is used to be inserted into a deep foundation pit. The horizontal adjustment assembly is used to adjust the distance between the bottom of the fixed base plate and the deep foundation pit. The telescopic assembly is arranged on the fixed base plate. The top of the telescopic assembly is rotatably connected to the rotating seat. The prism is rotatably arranged on the rotating seat.

[0006] Compared with the prior art, the present invention using the above technical solution has the following beneficial effects: The prism bracket of the present invention is provided with a fixed bottom plate as the base of the prism bracket, and a horizontal adjustment component is provided on the fixed bottom plate. The fixed distance between the fixed bottom plate and the deep foundation pit is adjusted by the horizontal adjustment component, and the height of the rotating seat is adjusted by the telescopic component, thereby adjusting the height of the prism on the rotating seat; the prism is rotatably set on the rotating seat, which is convenient for adjusting the angle of the prism individually, so that it can be quickly directed toward the total station, thereby improving the detection efficiency.

[0007] Preferably, a further technical solution of the present invention is: Each level adjustment component is inserted on the periphery of the fixed base plate, and the level adjustment component includes a positive and negative thread screw, a first handle and a positioning piece. The fixed base plate and the positioning piece are respectively threadedly connected to the upper and lower parts of the positive and negative thread screw, and the first handle is fixed to the top of the positive and negative thread screw. When the positive and negative thread screw rotates, the fixed base plate and the positioning piece move closer to or farther away from each other, and the positioning piece is used to abut against the deep foundation pit. By driving the positive and negative thread screw to rotate by the first handle, the distance between the fixed base plate and the positioning piece can be quickly adjusted, thereby quickly adjusting the height of each position of the fixed base plate to ensure the horizontality of the fixed base plate.

[0008] The telescopic assembly includes a threaded rod, a support tube and a fixed tube. The fixed tube is fixed on a fixed bottom plate. The support tube is movably inserted in the fixed tube. The top of the support tube is rotatably connected to the rotating seat. The threaded rod is rotatably arranged inside the fixed tube and is threadedly connected to the bottom of the support tube. The bottom of the threaded rod is connected to a rotating assembly for driving the threaded rod to rotate. The rotating assembly drives the threaded rod to rotate, so that the support tube threadedly connected to the threaded rod moves vertically, thereby driving the rotating seat at the top of the support tube to move vertically, thereby quickly adjusting the height of the prism.

[0009] The rotating assembly includes a first bevel gear, a second bevel gear and a second turning handle. The first bevel gear is fixedly sleeved at the bottom of the threaded rod, the second bevel gear is arranged inside the fixed cylinder and meshes with the first bevel gear, and the outer end of the second bevel gear extends to the outside of the fixed cylinder and is fixed to the second turning handle. The second bevel gear is driven to rotate by the second turning handle, which drives the first bevel gear to rotate synchronously, thereby driving the threaded rod to rotate.

[0010] The rotating seat comprises a mounting plate and two positioning plates fixed on the top of the mounting plate, and the two sides of the prism are rotatably connected to the two positioning plates respectively. Through the above structure, the prism is rotatably arranged on the rotating seat.

[0011] A rotating groove is provided in the middle of the mounting plate, a rotating block is fixed on the top of the support tube, and the rotating block is rotatably clamped in the rotating groove. Through the cooperation of the rotating groove and the rotating block, the rotating seat is rotatably connected with the top of the support tube.

[0012] A plurality of positioning balls are elastically inserted radially in the rotating block, and a plurality of positioning holes cooperating with the positioning balls are opened on the inner wall of the rotating groove. When the spring is in a natural state, the positioning balls are located in the positioning holes. The positions of the rotating block and the rotating groove are limited by the cooperation of the positioning balls and the positioning holes. BRIEF DESCRIPTION OF THE DRAWINGS
