Description

Technical Field

[0001] This utility model belongs to the field of surveying support technology, specifically relating to water conservancy surveying support. Background Technology

[0002] A surveying support is a component of surveying tools, used in conjunction with a surveying instrument to complete surveying tasks such as data acquisition, processing, and output.

[0003] Chinese patent application number 202220158367.6 proposes a portable support for water conservancy engineering surveying. It employs a mobile support structure, which allows for adjustments to the overall support height of the surveying equipment. Through built-in adjustment components and four casters, the equipment is supported as a whole, facilitating movement and reducing the workload of staff. This effectively solves the technical problem of existing water conservancy engineering surveying supports, which only provide support and require staff to lift the entire surveying equipment for movement, resulting in laborious operation.

[0004] However, when the device is moved, the moving wheels are simply extended by adjusting the components, without retracting the support tip. During movement, the support tip is prone to collisions and friction with the ground and roadside stones, resulting in severe wear and tear, affecting subsequent use. Furthermore, the exposed support tip can easily scratch workers, compromising the safe operation of the device. Utility Model Content

[0005] The purpose of this utility model is to provide a hydraulic surveying support, which solves the problem that the support tip of the existing surveying support is easily damaged during the movement process.

[0006] The technical solution adopted by this utility model is: a water conservancy surveying support, including a base, an installation plate connected to the surface of the base, a number of support legs evenly connected to the bottom of the base along its circumference, a telescopic leg slidably connected in each support leg, a second fixing bolt connected to one side of the support leg, a receiving groove opened at the end of the telescopic leg away from the support leg, a movable support component rotatably connected in the receiving groove, a movable component rotatably connected to the center of the bottom surface of the base, and the movable component is hinged to each support leg.

[0007] The feature of this utility model is that,

[0008] The moving component includes a threaded rod rotatably connected to the center of the bottom surface of the base. The rod body is connected to a threaded sleeve, and several guide rods are evenly hinged to the outer wall of the threaded sleeve along its circumference. Each guide rod is hinged to a support leg.

[0009] A knob is connected to the end of the threaded rod away from the base.

[0010] The top of the support leg is rotatably connected to the base via a connecting key.

[0011] Limiting grooves are provided on the inner walls of the supporting legs along their length, and limiting blocks are connected to the outer walls of the telescopic legs, with the limiting blocks matching the limiting grooves.

[0012] The movable support assembly includes a support block, with rotating shafts connected to opposite sides of the support block. The rotating shafts are rotatably connected to the inner wall of the receiving groove. An insertion hole is also provided on the side wall of the support block connected to the rotating shaft. A first fixing bolt is connected to the outer wall of the receiving groove. The first fixing bolt matches the insertion hole. A rolling unit and a support unit are respectively connected to opposite sides of the support block.

[0013] The support unit includes a support pin, with the larger end of the support pin connected to the support block.

[0014] The rolling unit includes a caster wheel, a rotating plate is rotatably connected to the top of the caster wheel, a damping telescopic rod is connected to the surface of the rotating plate, the end of the damping telescopic rod away from the rotating plate is connected to a support block, a spring is sleeved on the body of the damping telescopic rod, and the two ends of the spring are connected to the rotating plate and the support block respectively.

[0015] The beneficial effects of this utility model are:

[0016] This utility model of a hydraulic surveying support allows for easy movement. First, the entire support is lifted, the fixing bolts are rotated to lock, and then the support block is rotated so that the casters face downwards, storing the support pins in the receiving groove. The support block is then fixed in the desired position using the fixing bolts, and the support can be moved using the casters. Because the support pins are stored in the receiving groove during movement, they will not collide or rub against the ground or stones, protecting them and preventing them from scratching workers. When retracting the support, first, the fixing bolts are rotated to release the lock, the support block is rotated to store the support pins in the receiving groove, the casters face downwards, and the fixing bolts are used to secure them. The telescopic legs are pushed back into the support legs and secured with the second fixing bolt. Finally, a knob is used to rotate the threaded rod, which moves the threaded sleeve upwards, causing the support legs to retract via the guide rod, minimizing the support's size for easy carrying and storage.

Then, pull the telescopic leg 4 out of the support leg 3, adjust it to the required height, and fix it with the second fixing bolt 14. Turn the threaded rod 15 by the knob 16 to adjust the height of the threaded sleeve 17. The threaded sleeve 17 moves by itself, which drives the guide rod 18 to move, making it easy to open the support leg 3 and form a stable support structure. Turn the support block 6 so that the support nail 7 faces down. Then fix the position of the support nail 7 with the first fixing bolt 13 and insert the support nail 7 into the ground to provide stable support for the bracket.

[0068] When the support needs to be moved, first pull the support nail 7 out of the ground, turn the first fixing bolt 13 to unlock it, then turn the support block 6 so that the caster wheel 10 faces down, and store the support nail 7 in the receiving groove 5. Fix the support block 6 in the required position by the first fixing bolt 13, and then move the support by the caster wheel 10. The support nail 7 will not collide or rub against the ground or stones when it is moved, which is convenient to protect the support nail 7. The stored support nail 7 is also less likely to scratch the staff.

[0069] When folding the bracket, first turn the first fixing bolt 13 and the second fixing bolt 14 to unlock it, rotate the support block 6 so that the support pin 7 is stored in the receiving groove 5, turn the caster wheel 10 downward and fix it with the first fixing bolt 13, push the telescopic leg 4 back into the support leg 3 and fix it with the second fixing bolt 14, and finally turn the threaded rod 15 by the knob 16. The threaded rod 15 drives the threaded sleeve 17 to move upward, and the support leg 3 is folded up by the guide rod 18, so that the bracket is minimized in size and easy to carry and store.

[0070] This utility model of a hydraulic surveying support bracket has a support nail stored in a receiving groove when the bracket is moved.
