Abstract
Description
Technical Field
[0001] The utility model relates to a protective device for a parameter encoder and is applicable to the technical field of shaft survey equipment. Background Art
[0002] A vertical shaft is a well-shaped pipe with a vertical wall. It is actually a collapse funnel. It is square, long or irregularly round in plan. The long strip is developed along one set of joints, while the square or round is developed along two sets of joints. When surveying a vertical shaft, the vertical shaft detection equipment needs to arrange the parameter encoder in the vertical shaft.
[0003] However, the existing parameter encoder protection mechanism is simple, and the parameter encoder is prone to collide with the side wall of the shaft when moving downward in the shaft. After the collision, the parameter encoder is easily damaged. Therefore, in order to correct the above defects, we propose a parameter encoder device for detecting SBE operation in the shaft. Utility Model Content
[0004] The technical problem to be solved by the utility model is: in order to solve the above technical problem, the utility model provides a protective device for a parameter encoder.
[0005] The technical solution adopted by the utility model is: a protective device for a parameter encoder, characterized in that: it has:
[0006] A protective shell, wherein a mounting hole is formed on the top of the protective shell, and the parameter encoder is placed in the protective shell through the mounting hole;
[0007] A clamping mechanism is arranged in the protective housing and is used to clamp the parameter encoder in the protective housing;
[0008] The protective mechanism is arranged at the surrounding positions of the protective shell, and is used to protect the protective shell and the parameter encoder in the protective shell. In this way, when the parameter encoder is placed in the shaft and moved in the shaft, the parameter encoder can be stably clamped in the protective shell under the action of the clamping mechanism, and the parameter encoder can be effectively prevented from colliding with the inner wall of the shaft under the action of the protective shell. When the protective shell collides with the inner wall of the shaft, the protective mechanism can play a buffering role for the protective shell.
[0009] The clamping mechanism has at least two clamping blocks arranged in the protective shell, and the clamping blocks can clamp the parameter encoder in cooperation. A movable opening is formed at the bottom of the protective shell and at the corresponding position of the clamping block. A connecting rod is connected to the clamping block, and the end of the connecting rod extends out of the protective shell through the movable opening. A positioning block is installed at the end of the connecting rod extending out of the protective shell, and the positioning block and the protective shell are connected by a first bolt. In this way, after the parameter encoder is arranged in the protective shell, the positioning block is moved so that the connecting rod moves in the movable opening until the clamping block moves to a position where the parameter encoder can be clamped. At this time, the positioning block moves on the protective shell to the corresponding position of the first threaded hole on the positioning block and the second threaded hole on the protective shell. At this time, by tightening the first bolt between the positioning block and the protective shell, it is convenient to fix the clamping block at the position of clamping the parameter encoder.
[0010] A rubber pad is installed on the clamping block at a position in contact with the parameter encoder. In this way, the rubber pad can play a good anti-slip role and can effectively prevent the parameter encoder from falling off the clamping block when the clamping block clamps the parameter encoder.
[0011] The protection mechanism has at least two buffer mechanisms arranged at positions around the protection shell along the circumferential direction of the protection shell, so that when the protection shell collides at the positions around the protection shell, the buffer mechanisms at the positions can play a good buffering role.
[0012] The buffer mechanism comprises a protective plate mounted on the protective shell, a sleeve mounted on the side wall of the protective shell, a stopper block capable of slidingly cooperating with the sleeve mounted at a position corresponding to the sleeve on the protective plate, and a rubber block mounted in the sleeve. Thus, when the protective plate on the protective shell collides with the inner wall of the shaft, the stopper block on the protective plate moves into the sleeve on the protective shell and squeezes the rubber block during the movement, so that the rubber block plays a good buffering role.
[0013] A spring is also connected between the protective sleeve and the protective plate. In this way, the buffering effect between the protective plate and the protective housing can be enhanced under the action of the spring, and the protective plate can be prevented from falling off the protective housing.
[0014] Ventilation holes are formed on the side wall of the protective housing, so that the heat generated by the parameter encoder during operation can be dissipated.
[0015] A connecting plate is installed on the top of the protection housing, and a second bolt is installed on the connecting plate. Thus, by connecting the second bolt on the connecting plate with the shaft detection device, it is convenient to install the protection housing on the shaft detection device.
[0016] The beneficial effects of the utility model are as follows: the utility model provides a mounting hole on the top of the protective shell, so that the parameter encoder can be arranged in the protective shell through the mounting hole; the utility model provides a clamping mechanism in the protective shell, which is used to move the parameter encoder to a corresponding position in the movable opening on the protective shell through a connecting rod after the parameter encoder is arranged in the protective shell, at which time the parameter encoder in the protective shell is clamped by the clamping block on the connecting rod and the first threaded hole on the positioning block on the connecting rod is located at a position corresponding to the second threaded hole on the protective shell, and at this time the parameter encoder is clamped by the clamping block by tightening the first bolt on the positioning block and the protective shell; the utility model provides a protective mechanism on the side wall of the protective shell, so that when the protective shell collides with the side wall of the shaft, the limit block installed on the protective plate will extend into the sleeve on the protective shell and play a buffering role under the action of the rubber block in the sleeve, thereby further protecting the parameter encoder.

[0024] In this embodiment, there is a protective housing 1, a connecting plate 14 is installed on the top of the protective housing 1, and a second bolt 17 is installed on the connecting plate 14. In this way, the protective housing 1 can be easily installed on the shaft detection device by connecting the second bolt 17 to the shaft detection device.
[0025] In this embodiment, a mounting hole 8 is formed on the top of the protective housing 1 , and the parameter encoder 7 is conveniently mounted in the protective housing 1 through the mounting hole 8 .
[0026] In this embodiment, a clamping mechanism is provided in the protective shell 1, wherein a clamping block 2 is provided at a position corresponding to the parameter encoder 7 on the protective shell 1, a rubber pad 15 is installed on the clamping block 2 at a position in contact with the parameter encoder 7, a movable opening 4 is formed on the protective shell 1 at a position corresponding to the clamping block 2, a movable connecting rod 3 is installed in the movable opening 4, one end of the connecting rod 3 is connected to the clamping block 2, and the other end of the connecting rod 3 extends out of the protective shell 1 and is connected to the positioning block 5, a first threaded hole is formed on the positioning block 5, and a second threaded hole is formed on the protective shell 1. When the clamping block 2 moves to a position where the parameter encoder 7 can be clamped, the positioning block 5 moves to a position corresponding to the first threaded hole on the positioning block 5 and the second threaded hole on the protective shell 1. At this time, by installing the first bolt 6 on the positioning block 5 and the protective shell 1, it is convenient for the clamping block 2 to clamp the parameter encoder 7.
[0027] In this embodiment, a protective mechanism is arranged around the protective shell 1, wherein four buffer mechanisms are evenly arranged at positions around the protective shell 1 along the circumferential direction of the protective shell 1. In this embodiment, the buffer mechanism has a protective plate 9 installed on the protective shell 1, a sleeve 11 is installed on the side wall of the protective shell 1, a limit block 10 that can slide with the sleeve 11 is installed at a position corresponding to the sleeve 11 on the protective plate 9, a rubber block 12 is also installed in the sleeve 11, and a spring 13 is also connected between the protective sleeve 11 and the protective plate 9.
