Abstract
Description
Technical Field
[0001] This utility model relates to the field of geological engineering surveying technology, and in particular to a positioning device for a surveying instrument used in geological engineering surveying. Background Technology
[0002] A geodetic instrument positioning device is a device specifically designed for the precise positioning of geodetic instruments in geological engineering surveying. It generally consists of a high-precision positioning sensor, a stable support structure, a data transmission module, and an intelligent control system. The positioning sensor can quickly and accurately acquire the three-dimensional coordinate information of the geodetic instrument in the geological environment, while the support structure provides stable support for the geodetic instrument, ensuring that it maintains the correct posture under different terrain and working conditions.
[0003] Chinese patent CN222732566U discloses a positioning device for a surveying instrument used in geological engineering surveying. The device includes a mounting base, with a connecting frame arranged in a ring array fixedly connected to the outer contour of the mounting base. A support frame is movably connected to the inner wall of the connecting frame, and a telescopic rod is slidably connected through and limited by the support frame. A positioning mechanism is provided on the upper surface of the mounting base. This invention, by setting an adjustment mechanism, allows for rapid and precise adjustment of the surveying instrument simply by rotation, compared to traditional bolt adjustment methods. This greatly improves operational convenience and effectively prevents the surveying instrument's position from easily shifting, ensuring the accuracy of the surveying results. It has the advantages of convenient operation, rapid and stable operation, high reliability, and high adjustment accuracy, significantly improving the efficiency and accuracy of geological engineering surveying.
[0004] Existing technologies often have the following drawbacks: when using the support legs of a surveying instrument, the support legs are often adjusted by directly inserting bolts into the sockets, which is inefficient. Using a lead screw drive plug requires the lead screw to work for a long time, which reduces the efficiency of adjusting the support legs.
[0005] Therefore, this utility model provides a positioning device for a surveying instrument used in geological engineering surveying. Utility Model Content
[0006] The purpose of this invention is to address the shortcomings of existing technologies, such as the inconvenience of quickly and accurately adjusting the height of the support legs, and to propose a positioning device for a geological engineering surveying instrument.
[0007] To achieve the above objectives, the present invention adopts the following technical solution: a positioning device for a geological engineering surveying instrument, comprising a mounting base, three rotating bars rotatably connected to the side wall of the mounting base, a support leg slidably connected inside the rotating bars, an adjustment structure on the surface of the support leg, the adjustment structure including a sliding plate slidably connected inside the support leg, a plug fixedly connected to the lower end of the sliding plate, the lower end of the plug being a pointed structure, a pin slidably passing through the side wall of the rotating bars, and an insertion hole opened on the side wall of the support leg, the size of the pin matching the size of the insertion hole.
[0008] The effect achieved by the above components is that by setting up the adjustment device and adjusting the bottom support of the surveying instrument twice, the surveying instrument can be placed quickly and accurately, which improves the adjustment efficiency of the surveying instrument to a certain extent.
[0009] Preferably, a retaining ring is fixedly connected to the side wall of the pin, and a spring is sleeved on the surface of the pin, with the two ends of the spring being fixedly connected to the retaining ring and the rotating bar, respectively.
[0010] The effect achieved by the above components is that, under the elastic force of the spring, the pin is re-inserted into the corresponding hole, thereby achieving a coarse adjustment of the height of the support leg.
[0011] Preferably, a first mounting block is fixedly connected to the side wall of the plug, and a second mounting block is fixedly connected to the side wall of the support leg. A screw is threadedly connected to the inside of the second mounting block, and the screw is rotatably connected to the inside of the first mounting block.
[0012] The effect achieved by the above components is as follows: when the screw is rotated, because the screw is threadedly connected to the second mounting block and rotatably connected to the first mounting block, the first mounting block will drive the plug to move slowly up and down on the slide plate inside the support leg as the screw rotates.
[0013] Preferably, the side wall of the plug is provided with a protective structure, the protective structure including a rectangular block fixedly connected to the surface of the plug, a sliding frame slidably connected inside the rectangular block, a protective frame fixedly connected to the lower end of the sliding frame, the protective frame being a rectangular ring structure, and the sliding frame being a U-shaped structure.
[0014] The effect achieved by the above-mentioned components is that by setting up a protective structure, it facilitates flexible protection of the plug end and further improves the safety performance of the plug position.
[0015] Preferably, the rectangular block is made of metal iron, and a magnetic block is fixedly connected to the upper surface of the protective frame.
[0016] The effect achieved by the above components is that the magnetic block on the protective frame will be attracted to the rectangular block, thereby enabling the plug to be used in an exposed manner.
[0017] Preferably, a pivot pin is rotatably connected to the upper surface of the rectangular block, and a pivot plate is fixedly connected to the side wall of the pivot pin.
[0018] The effect achieved by the above components is that by rotating the pivot pin, the stop block is blocked above the sliding frame, which can provide temporary support for the protective frame after it is moved.
[0019] Preferably, an elastic pad is fixedly connected to the lower surface of the rotating plate, and the elastic pad has a frustum-shaped structure.
[0020] The effect achieved by the above components is that the elastic pad improves the tightness of the obstruction of the sliding frame.
[0021] In summary:
[0022] 1. In this utility model, the first mounting block will drive the plug to move slowly up and down on the slide plate inside the support leg, thereby precisely adjusting the height of the support leg and realizing the precise adjustment of the surveying instrument's posture to meet the requirements of high-precision surveying. By setting the adjustment device, the surveying instrument can be quickly and accurately placed by adjusting the bottom bracket of the surveying instrument twice, which improves the adjustment efficiency of the surveying instrument to a certain extent.
[0023] 2. In this utility model, the elastic pad improves the tightness of the shielding of the sliding frame. The protective frame can shield the end of the plug, preventing the plug from piercing the operator. When the plug needs to be used, the rotating block can be turned out and the protective frame can be lifted. The magnetic block on the protective frame will be attracted to the rectangular block, thereby enabling the plug to be used without contact. By setting the protective structure, flexible protection of the plug end is facilitated, further improving the safety performance of the plug position. Attached Figure Description

Detailed Implementation
[0029] Reference Figure 1 As shown, this utility model provides a technical solution: a positioning device for a geological engineering surveying instrument, including a mounting base 1, three rotating bars 2 rotatably connected to the side wall of the mounting base 1, a support leg 3 slidably connected inside the rotating bar 2, an adjustment structure 4 on the surface of the support leg 3, and a protective structure 5 on the side wall of the plug 46.
[0030] The specific settings and functions of its adjustment structure 4 and protection structure 5 will be explained below.
[0031] Reference Figure 1-2 As shown in this embodiment: the adjustment structure 4 includes a sliding plate 45 slidably connected inside the support leg 3. A plug 46 is fixedly connected to the lower end of the sliding plate 45. The lower end of the plug 46 has a pointed structure. A pin 41 is slidably inserted through the side wall of the rotating bar 2. A socket 44 is opened on the side wall of the support leg 3. The size of the pin 41 matches the size of the socket 44. By setting up the adjustment device, the quick and accurate placement of the surveying instrument is facilitated through two adjustments to the bottom support of the surveying instrument, thus improving the adjustment efficiency of the surveying instrument to a certain extent. A retaining ring 42 is fixedly connected to the side wall of the pin 41. A spring 43 is sleeved on the surface of the pin 41. The two ends of the spring 43 are fixedly connected to the retaining ring 42 and the rotating bar 2, respectively. Under the elastic force of the spring 43, the pin 41 re-inserts into the corresponding socket 44, realizing a coarse adjustment of the height of the support leg 3. A first mounting block 47 is fixedly connected to the side wall of the plug 46, and a second mounting block 49 is fixedly connected to the side wall of the support leg 3. A screw 48 is threadedly connected to the inside of the second mounting block 49, and the screw 48 and the first mounting block 47 are rotatably connected internally. When the screw 48 is rotated, because the screw 48 is threadedly connected to the second mounting block 49 and rotatably connected to the first mounting block 47, the first mounting block 47 will drive the plug 46 to move slowly up and down on the slide plate 45 inside the support leg 3.
[0032] Reference Figure 1-4As shown, specifically, the protective structure 5 includes a rectangular block 53 fixedly connected to the surface of the plug 46. A sliding frame 51 is slidably connected inside the rectangular block 53, and a protective frame 52 is fixedly connected to the lower end of the sliding frame 51. The protective frame 52 is a rectangular ring structure, and the sliding frame 51 is a U-shaped structure. By setting the protective structure 5, flexible protection of the plug 46 end is facilitated, further improving the safety performance of the plug 46 position. The rectangular block 53 is made of iron, and a magnetic block 57 is fixedly connected to the upper surface of the protective frame 52. The magnetic block 57 on the protective frame 52 will adhere to the rectangular block 53, thus enabling the plug 46 to be used exposed. A pivot pin 54 is rotatably connected to the upper surface of the rectangular block 53, and a pivot plate 55 is fixedly connected to the side wall of the pivot pin 54. Rotating the pivot pin 54 blocks the block above the sliding frame 51, providing temporary support for the protective frame 52 after movement. An elastic pad 56, which is a frustum-shaped structure, is fixedly connected to the lower surface of the pivot plate 55. The elastic pad 56 improves the tightness of the occlusion of the slide frame 51.
[0033] Working principle: When using the positioning device of this geological engineering surveying instrument, a coarse adjustment is first performed. When it is necessary to adjust the height of the support leg 3, pull the pin 41 to disengage it from the insertion hole 44 on the side wall of the support leg 3. At this time, the retaining ring 42 will move with the pin 41, compressing the spring 43. Since the pin 41 is no longer restricted by the insertion hole 44, the support leg 3 can slide along the rotating bar 2 to the approximate desired position. Release the pin 41, and under the elastic force of the spring 43, the pin 41 will re-insert into the corresponding insertion hole 44, thus achieving a coarse adjustment of the height of the support leg 3 and quickly adjusting the surveying instrument to a near-horizontal or suitable viewing position. After measuring the height range and coarsely adjusting, fine adjustment is performed by rotating screw 48. Since screw 48 is threadedly connected to the second mounting block 49 and rotatably connected to the first mounting block 47, as screw 48 rotates, the first mounting block 47 will drive the plug 46 to slowly move up and down on the slide plate 45 inside the support leg 3, thereby precisely adjusting the height of the support leg 3 and achieving precise adjustment of the surveying instrument's posture to meet the high-precision requirements of surveying. By setting up the adjustment device and performing two adjustments on the bottom support of the surveying instrument, the quick and accurate placement of the surveying instrument is facilitated, and the adjustment efficiency of the surveying instrument is improved to a certain extent.
[0034] When the positioning device needs to be carried, the sliding frame 51 inside the rectangular block 53 can be slid. After the sliding frame 51 moves to a position that fits against the surface of the rectangular frame, the pivot pin 54 is rotated to block the top of the sliding frame 51, which can temporarily support the protective frame 52 after it has been moved. The elastic pad 56 improves the tightness of the blockage of the sliding frame 51. The protective frame 52 can block the end side of the plug 46, which can prevent the plug 46 from piercing the staff. When the plug 46 needs to be used, the pivot block can be turned out and the protective frame 52 can be lifted. The magnetic block 57 on the protective frame 52 will be attracted to the rectangular block 53, thereby enabling the plug 46 to be used in an exposed position. By setting the protective structure 5, the flexible protection of the end side of the plug 46 is facilitated, and the safety performance of the plug 46 position is further improved.
