Description

Technical Field

[0001] The invention relates to the technical field of measurement, and in particular to a mounting bracket for total station measurement. Background Art

[0002] A total station, or total station electronic distance meter, is a high-tech measuring instrument that integrates optics, mechanics, and electronics. It is a surveying and mapping instrument system that integrates horizontal angle, vertical angle, distance (slant distance, horizontal distance), and height difference measurement functions. It is called a total station because it can complete all measurement work at the survey station after one installation of the instrument. It is widely used in precision engineering measurement or deformation monitoring fields such as large-scale ground buildings and underground tunnel construction. When in use, the total station requires a total station bracket to support and install it.

[0003] The existing total station bracket is in a horizontal state by adjusting the height of its three sets of brackets when in use, and it is not convenient to adjust the bracket level through the three sets of brackets. In addition, in order to improve the overall portability, the existing brackets are usually manufactured using three materials: wood, fiberglass and aluminum alloy. However, when the total station is in a measurement site with strong winds, such lightweight brackets cannot stably support the total station, thereby affecting the measurement process and measurement results. Summary of the invention

[0004] The object of the present invention is to provide a mounting bracket for total station measurement to solve the above-mentioned defects caused by the prior art.

[0005] A mounting bracket for total station measurement comprises a connecting base, wherein a plurality of connecting blocks are evenly connected to the connecting base around the connecting base, a pair of connecting tubes are vertically connected to the lower side of each connecting block, and the lower end of each pair of connecting tubes is commonly connected to a connecting frame, a movable tube is slidably connected to the inner side of the connecting frame, and a locking structure is provided at the upper end of the movable tube, wherein the locking structure comprises a mounting shell, a pair of mounting holes are symmetrically provided on the left and right sides of the mounting shell, and the connecting tubes located on the same side are slidably connected to the mounting holes, a pair of locking blocks are symmetrically distributed on the left and right sides of the mounting shell, and a plurality of compression springs are evenly connected between the pair of locking blocks, a pair of pressing grooves are symmetrically provided on the upper and lower sides of the mounting shell, and a pair of pressing blocks are symmetrically distributed on the upper and lower sides of the mounting shell, the inner end of the locking block is an isosceles trapezoidal structure, the left and right ends of the pressing block are both right-angled triangle structures, and the inclined surface on the mounting block is in sliding contact with the inclined surface on the locking block.

[0006] Preferably, magnet blocks are evenly distributed around the mounting hole, a piston block is magnetically attracted between each group of magnet blocks, and the piston block is slidably connected to the connecting pipe, the interior of the connecting pipe is filled with clean water, a fixed pulley is fixed to the side of the mounting shell, a water pipe is wound around the fixed pulley, and both ends of the water pipe are respectively connected to the lower part of the connecting pipe and the movable pipe.

[0007] Preferably, an inlet and an outlet are provided at the lower portion of the connecting pipe, and sealing covers are threadedly installed at the inlet and the outlet.

[0008] Preferably, the outer end of the locking block is an arc surface, and the arc surface is densely covered with anti-slip textures.

[0009] Preferably, a mounting sleeve is installed at the lower end of the movable tube, a soil nail is integrally connected to the lower side of the mounting sleeve, and a pressure plate is integrally connected to the outer side of the mounting sleeve.

[0010] Compared with the prior art, the present invention has the following advantages:

[0011] 1. Easy and quick adjustment. When a pair of mounting blocks in each pair of locking structures are pressed at the same time, the left and right locking blocks can be driven to move closer to each other and the locking blocks can be separated from the connection pipe, so that the installation shell can move up and down along the connection pipe; when a pair of mounting blocks in each pair of locking structures are released at the same time, the left and right locking blocks can be separated from each other under the action of the compression spring, and the locking blocks can be re-contacted with the connection pipe, so that the installation shell can be temporarily locked on the connection pipe.

[0012] 2. Stable support and easy to carry. When the mounting shell moves downward along the connecting tube, the magnet block on the mounting shell is used to synchronously drive the piston block to move downward, and the clean water in the connecting tube is squeezed into the movable tube through the water pipe, thereby lowering the center of gravity height of the bracket and improving the stability of the bracket when in use. When the mounting shell moves upward along the connecting tube, the magnet block on the mounting shell is used to synchronously drive the piston block to move downward, and the clean water in the movable tube is sucked into the connecting tube through the water pipe, and then the clean water in the connecting tube is discharged, thereby improving the portability of the bracket when carried.

DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0022] like Figures 1 to 6 As shown, a total station measurement mounting bracket includes a connecting base 10, wherein a plurality of connecting blocks 11 are evenly connected around the connecting base 10, a pair of connecting pipes 12 are vertically connected to the lower side of each connecting block 11, and a connecting frame 14 is commonly connected to the lower end of each pair of connecting pipes 12, and a movable pipe 15 is slidably connected to the inner side of the connecting frame 14, and a locking structure 16 is provided at the upper end of the movable pipe 15, and the locking structure 16 includes a mounting shell 161, and a pair of mounting holes 161a are symmetrically provided on the left and right sides of the mounting shell 161, and the connecting pipes 12 on the same side are slidably connected to the mounting shell 161. Connected to the mounting hole 161a, a pair of locking blocks 162 are symmetrically distributed inside the mounting shell 161, and a number of compression springs 164 are evenly connected between the pair of locking blocks 162. A pair of pressing grooves 161b are symmetrically provided on the upper and lower sides of the mounting shell 161. A pair of pressing blocks 163 are symmetrically distributed inside the mounting shell 161. The inner end of the locking block 162 is an isosceles trapezoidal structure, and the left and right ends of the pressing block 163 are both right-angled triangle structures, and the inclined surface on the mounting block 163 is in sliding contact with the inclined surface on the locking block 162. When a pair of mounting blocks 163 in each pair of locking structures 16 are pressed at the same time, the left and right locking blocks 162 can be driven to approach each other, and the locking blocks 162 can be separated from the contact with the connecting tube 12, so that the mounting shell 161 can move up and down along the connecting tube 12; when a pair of mounting blocks 163 in each pair of locking structures 16 are released at the same time, the left and right locking blocks 162 can be separated from each other under the action of the compression springs 164, and the locking blocks 162 can be re-contacted with the connecting tube 12, so that the mounting shell 161 can be temporarily locked on the connecting tube 12.

[0023] In this embodiment, magnet blocks 165 are evenly distributed around the mounting hole 161a, and piston blocks 166 are magnetically attracted between each group of magnet blocks 165, and the piston blocks 166 are slidably connected to the connecting pipe 12, and the interior of the connecting pipe 12 is filled with clean water. A fixed pulley 20 is fixed to the side of the mounting shell 161, and a water pipe 21 is wound around the fixed pulley 20, and the two ends of the water pipe 21 are respectively connected to the lower part of the connecting pipe 12 and the movable pipe 15. When the mounting shell 161 moves downward along the connecting pipe 12, the magnet blocks 165 on the mounting shell 161 are used to synchronously drive the piston block 166 to move downward, and the clean water in the connecting pipe 12 is squeezed into the movable pipe 15 through the water pipe 21, thereby reducing the center of gravity height of the bracket and improving the stability of the bracket when in use. When the mounting shell 161 moves upward along the connecting pipe 12, the magnet block 165 on the mounting shell 161 synchronously drives the piston block 166 to move downward, and the clean water in the movable tube 15 is sucked into the connecting pipe 12 through the water pipe 21, and then the clean water in the connecting pipe 12 is discharged, thereby improving the portability of the bracket when carried.

[0024] In this embodiment, the lower part of the connecting tube 12 is provided with an inlet and outlet 12a, and a sealing cover 13 is threadedly installed at the inlet and outlet 12a. When water from the outside enters the connecting tube 12 through the inlet and outlet 12a, the weight of the connecting tube 12 itself can be increased, thereby improving the stability of the bracket when in use; when the water in the connecting tube 12 is discharged through the inlet and outlet 12a, the weight of the connecting tube 12 itself can be reduced, thereby improving the convenience of carrying the bracket.

[0025] In this embodiment, the outer end of the locking block 162 is an arc surface, and the arc surface is densely covered with anti-slip textures. The arc surface can increase the contact area between the locking block 162 and the connecting pipe 12, and the protective texture can increase the friction resistance between the locking block 162 and the connecting pipe 12.

[0026] In this embodiment, a mounting sleeve 17 is installed at the lower end of the movable tube 15, a soil nail 18 is integrally connected to the lower side of the mounting sleeve 17, and a pressing plate 19 is integrally connected to the outer side of the mounting sleeve 17. The mounting sleeve 17 can be used to protect the lower end of the movable tube 15, and at the same time, the soil nail 18 and the pressing plate 19 can be used to conveniently fix the lower end of the movable tube 15.

[0027] Working principle of this total station measurement mounting bracket:

[0028] When a pair of mounting blocks 163 in each pair of locking structures 16 are pressed simultaneously, the left and right locking blocks 162 can be driven to approach each other and the locking blocks 162 can be separated from the connection tube 12 , so that the mounting shell 161 can move up and down along the connection tube 12 .

[0029] When the mounting shell 161 moves downward along the connecting pipe 12, the magnet block 165 on the mounting shell 161 synchronously drives the piston block 166 to move downward, and squeezes the clean water in the connecting pipe 12 into the movable pipe 15 through the water pipe 21, thereby lowering the center of gravity height of the bracket and improving the stability of the bracket during use.

[0030] When the mounting shell 161 moves downward along the connecting pipe 12, the magnet block 165 on the mounting shell 161 synchronously drives the piston block 166 to move downward, and squeezes the clean water in the connecting pipe 12 into the movable pipe 15 through the water pipe 21, thereby lowering the center of gravity height of the bracket and improving the stability of the bracket during use.

[0031] When a pair of mounting blocks 163 in each pair of locking structures 16 are released at the same time, the left and right locking blocks 162 can be moved away from each other under the action of the compression spring 164, and the locking blocks 162 can be re-contacted with the connecting pipe 12, so that the mounting shell 161 can be temporarily locked on the connecting pipe 12.

[0032] Therefore, the embodiments disclosed above are only illustrative in all aspects and are not exclusive. All changes within the scope of the present invention or within the scope equivalent to the present invention are included in the present invention.
