[0029] In one embodiment of the present application, as shown in ​ A total station shock-absorbing device is installed at the bottom of a total station 1, and includes a shock-absorbing assembly 2 and a switching assembly 3.

[0030] As shown in ​As shown, wherein the damping assembly 2 is installed at the bottom of the total station 1, which is used for buffering and damping of the total station 1, the damping assembly 2 comprises a base fixing plate 23 arranged at the bottom of the total station 1, a column support plate 24 arranged at the bottom of the base fixing plate 23, and an elastic element 25 connected between the base fixing plate 23 and the column support plate 24, a pull rod 28 is movably penetrated on the column support plate 24, one end of the pull rod 28 extends upward until it protrudes from the top surface of the base fixing plate 23, and the end of the pull rod 28 protruding from the top surface of the base fixing plate 23 is fixedly connected with the base fixing plate 23 through a fixing nut 29, a plurality of positioning columns 26 are fixed on the column support plate 24, one end of the positioning column 26 is fixed with a first positioning pin 27, and a plurality of first pin holes matched with the first positioning pin 27 are formed on the base fixing plate 23;

[0031] The damping assembly 2 provides elastic force through the elastic element 25, which is specifically a spring, to buffer and damp the total station 1, avoid instability and damage of the total station 1 itself, and through the arrangement of the pull rod 28 which can vertically slide on the column support plate 24, and the upper end of the pull rod 28 is fixed on the base fixing plate 23 through the fixing nut 29, since the base fixing plate 23 is arranged above the column support plate 24, the movement of the pull rod 28 can drive the base fixing plate 23 to freely slide on the column support plate 24;

[0032] Meanwhile, by arranging the first positioning pin 27 and the first pin hole, when the base fixing plate 23 moves to cooperate with the first positioning pin 27 and the first pin hole, the first positioning pin 27 is inserted into the first pin hole, at this time, under the limiting action of the first positioning pin 27, and at this time, the pull rod 28 is in a fixed state, at this time, the base fixing plate 23 and the column support plate 24 are connected and supported through the fixing column 26, so as to fix the total station 1, which is the fixed state, in the fixed state, the total station 1 can be measured and other processes in the fixed state to ensure the measurement accuracy of the total station 1, and when the base fixing plate 23 moves to the first positioning pin 27 and the first pin hole do not cooperate, that is, a certain gap is left between the first positioning pin 27 and the first pin hole, at this time, the base fixing plate 23 and the column support plate 24 are connected and supported through the elastic element 25, so as to loosen the total station 1, which is the damping state, in the damping state, when the total station 1 moves on the track, the unevenness of the track will cause the total station 1 to shake, under the elastic force of the elastic element 25, the total station 1 can be buffered and damped, that is, the influence of vibration on the total station 1 is reduced and the structure of the total station 1 is protected, avoiding damage;

[0033] It is worth mentioning that the size of the first positioning pin 27 is smaller than the size of the positioning column 26, so that when the base fixing plate 23 moves to the first positioning pin 27 and the first pin hole is matched, the movement position of the base fixing plate 23 can be limited by the positioning column 26, so as to avoid excessive movement of the base fixing plate 23, which may cause excessive compression of the elastic element 25, which may cause the total station 1 to receive sudden elastic force, thereby damaging the structure thereof.

[0034] As shown in ​ 、 4 The switching assembly 3 is installed at the bottom of the damping assembly 2, the switching assembly 3 includes a shell 31 fixed at the bottom of the column support plate 24 and a connecting rod mechanism arranged in the shell 31, the connecting rod mechanism includes a bearing plate 36 fixed on the inner wall of the shell 31 and a rotating piece 34 rotatably connected to the bearing plate 36 through a movable shaft 37, the rotating piece 34 is rotatably connected with a U-shaped rod 35 through a connecting shaft, one end of the U-shaped rod 35 away from the connecting shaft is movably connected with the pull rod 28, the other end of the rotating piece 34 away from the movable shaft 37 is connected with a switching wrench 33 through a wrench connecting plate 32, the switching wrench 33 is used to drive the rotating piece 34 to rotate around the movable shaft 37, so that the pull rod 28 drives the base fixing plate 23 to move towards or away from the column support plate 24;

[0035] The switching assembly 3 is used to control the total station 1 to switch from the damping state to the fixed state or from the fixed state to the damping state, specifically, the rotating piece 34 is approximately arc-shaped, one end of the rotating piece 34 is connected with the bearing plate 36 through the movable shaft 37, and the other end is connected with the switching wrench 33 through the wrench connecting plate 32, and the connecting shaft is connected at the middle position of the rotating piece 34, by turning the switching wrench 33, the rotating piece 34 can rotate around the movable shaft 37, at the same time of rotating, the U-shaped rod 35 is fixed with the connecting shaft, the U-shaped rod 35 also rotates around the connecting shaft, and one end of the U-shaped rod 35 moves with the rotating piece 34, thereby driving the pull rod 28 to move up and down, and further driving the base fixing plate 23 to move towards or away from the column support plate 24, so as to control the total station 1 to switch from the damping state to the fixed state or from the fixed state to the damping state;

[0036] Specifically, the switching process is as follows:

[0038] When the total station 1 is switched from the fixed state to the damping state, the switching wrench 33 is pulled counterclockwise, the rotating part 34 is rotated counterclockwise around the movable shaft 37, the end of the pull rod 28 is pulled upward, the fixed nut 28 at the upper end of the pull rod 28 is moved upward, the base fixing plate 23 is moved away from one side of the column support plate 24, until the first positioning pin 27 is completely separated from the first pin hole, at this time, there is a gap between the first positioning pin 27 and the first pin hole, at this time, the base fixing plate 23 and the column support plate 24 are connected and supported through the elastic element 25, the total station 1 is in a loose state, at this time, the total station 1 is in a damping state, and movement on the track can be performed.

[0040] Specifically, the mounting base 21 can be connected and fixed with the docking structure at the bottom of the total station 1, after the total station 1 is used completely, the corresponding docking mechanism can be disengaged from the mounting base 21, then the total station 1 can be packed and stored, and meanwhile, the mounting base 21 and the base fixing plate 23 can be separated through the supporting columns 22, so as to leave enough space for the installation of the fixed nut 29.

[0041] In the embodiment, the fixed nut 29 is connected with the base fixing plate 23 through a disc spring 210;

[0042] Specifically, the disc spring 210 itself has a certain elasticity, during the upward and downward movement of the base fixing plate 23 driven by the fixed nut 29, rigid friction and collision may occur between the fixed nut 29 and the base fixing plate 23, the elastic force provided by the disc spring 210 can provide a buffer force between the fixed nut 29 and the base fixing plate 23, so as to prolong the service life of the equipment.

[0043] In the embodiment, one side of the shell 21 is fixed with a handle, and one side of the shell 31 is provided with an open slot for the activity of the switching handle 33.

[0044] The handle can facilitate the staff to carry the total station shock-absorbing device or the separate switching assembly 3, and the open slot is arranged on one side of the shell 31 to expose the switching handle 33, so that the switching handle 33 can be manually or mechanically turned in the actual operation process, but most of them are manually turned to switch the state of the total station 1, so that the switching handle 33 is exposed through the open slot to facilitate the staff to turn the switching handle 33.

[0047] In the embodiment, the pull rod 28 is fixed with a pull block 211 at one end away from the fixing nut 29, the pull block 211 is provided with a running groove, and one end of the U-shaped rod 35 is movably connected in the running groove.

[0048] The running groove has a certain length, so that one end of the U-shaped rod 35 can slide and rotate in the running groove, so that the U-shaped rod 35 will not be stuck when the rotating piece 34 rotates, to ensure that the U-shaped rod 35 can normally move up and down.

[0049] As shown in ​ In the embodiment, the total station shock-absorbing device further comprises a mounting assembly 4, which comprises a mounting bottom plate 41 fixed at the bottom of the shell 31 and a mounting base 42 arranged below the mounting bottom plate 41.

[0052] When the mounting assembly 4 is installed, the handle 44 can be rotated to drive the locking nut 45 to rotate on the mounting base plate 41. Since the movable screw rod 47 is threadedly connected with the locking nut 45, the rotation of the locking nut 45 can drive the movable screw rod 47 to ascend or descend. Since the end of the movable screw rod 47 is connected with the sleeve 48 and the fixed rod 46, and the fixed rod 46 is fixed on the mounting base 42, the rotation of the locking nut 45 can drive the mounting base 42 to ascend or descend. Since the mounting base 42 is generally installed on a track or a measuring mechanism and cannot ascend or descend by itself, the rotation of the locking nut 45 can drive the mounting base plate 41, the total station 1, the damping assembly 2 and the switching assembly 3 arranged on the mounting base plate 41 to move towards or away from the mounting base 42.

[0053] It can be understood that when the mounting base plate 41 moves towards the mounting base 42, the mounting base 42 and the mounting base plate 41 can be locked and fixed through the locking nut 45 and the fixed rod 46. When the mounting base plate 41 moves away from the mounting base 42, the mounting base plate 41 and the mounting base 42 are in an unlocked state, which is convenient for subsequent disassembly and movement.

[0054] In the embodiment, the bottom of the mounting base plate 41 is fixed with a cylindrical pin 43 and a second positioning pin 49, and the mounting base 42 is provided with a cylindrical pin hole matched with the cylindrical pin 43 and a second pin hole matched with the second positioning pin 49.
