Surveying and mapping equipment generally refers to instruments and devices for data acquisition, processing, output, etc. designed and manufactured for surveying and mapping operations; before the construction of municipal engineering, it is necessary to measure the terrain during the planning and design, construction, and operation and management stages of the construction through surveying and mapping equipment.

[0003] The existing surveying and mapping equipment for municipal engineering often needs to be moved between different measurement points during surveying and mapping, usually carried manually by surveying and mapping personnel, increasing the labor intensity of surveying and mapping personnel and making it inconvenient to move the surveying and mapping equipment. Content of the Utility Model

[0004] In order to solve the above problems, the utility model provides a terrain surveying and mapping auxiliary equipment for municipal engineering.

[0005] The above technical purpose of the utility model is achieved through the following technical solutions: A terrain surveying and mapping auxiliary equipment for municipal engineering includes a base for installing surveying and mapping equipment. A plurality of support legs are hinged to the bottom of the base. A moving plate slidably connected to the support leg is sleeved on each support leg. A support rod is fixed to the bottom of the moving plate, and a universal wheel is fixed to the lower end of the support rod. A lifting assembly for lifting the moving plate is installed on each support leg. An installation seat is fixed to the bottom of the base, and a limiting assembly for limiting the support leg is installed on the installation seat.

[0006] By adopting the above technical solutions, when it is necessary to move the surveying and mapping equipment, the staff retracts the support legs and then limits the support legs through the limiting assembly, and then drives the moving plate to move downward through the lifting assembly, so that the support rod drives the universal wheel to contact the ground downward and lift the support legs, thereby moving the base and the surveying and mapping equipment through the universal wheel, eliminating the laborious operation of manually carrying the surveying and mapping equipment and facilitating the movement of the surveying and mapping equipment.

[0007] Furthermore, each group of the lifting assemblies includes a mounting plate fixed to the side wall of the support leg, a threaded rod penetrating through the mounting plate and threadedly connected thereto, and a star-shaped handle fixed to the upper end of the threaded rod. The lower end of the threaded rod is rotatably connected to the upper surface of the moving plate.

[0008] By adopting the above technical solution, when the movable plate needs to be raised or lowered, the staff rotates the threaded rod through the star-shaped handle. Since the threaded rod is threadedly connected to the mounting plate, the threaded rod is rotationally connected to the movable plate, and the movable plate is slidingly connected to the support legs, the movable plate can be raised or lowered on the support legs, making it easy to adjust the height of the support rod and the universal wheel.

[0009] Furthermore, each of the side walls of the supporting legs is provided with a limiting groove, and the limiting components are provided in multiple groups, each group of the limiting components includes a fixed block fixed to the side wall of the mounting seat, a limiting rod penetrating through the side wall of the fixing block and slidably connected, and a pulling block fixed to one end of the limiting rod away from the supporting leg, and the limiting rod is plugged into the limiting groove.

[0011] Furthermore, a fixing groove is formed on the side wall of the fixing block, a spring is arranged in the fixing groove, the spring is sleeved on the limiting rod, one end of the spring is fixed to the inner wall of the fixing groove, and the other end of the spring is fixed to the side wall of the pulling block.

[0012] By adopting the above technical solution, the pulling block keeps the limiting rod in the plugged state with the limiting groove under the elastic force of the spring, thereby reducing the probability that the limiting rod is separated from the limiting groove and the supporting leg is opened.

[0013] Furthermore, a side wall of the limiting rod away from the mounting seat is provided with a yielding portion that cooperates with the side wall of the supporting leg.

[0014] By adopting the above technical solution and setting the yielding part, the supporting leg can squeeze the limiting rod into the fixing block through the yielding part during the folding process, and then the limiting rod and the limiting groove are automatically plugged into each other under the elastic force of the spring, eliminating the tedious operation of the staff to manually pull the pulling block, and facilitating the rapid fixation of the supporting leg.

[0015] Furthermore, an arc groove is provided on the side wall of the supporting leg, a ball rollingly connected to the inner wall of the arc groove is provided on the inner wall of the movable plate, and the gap distance between the inner wall of the movable plate and the side wall of the supporting leg is 0.1-0.3 mm.

[0016] By adopting the above technical solution, the ball bearings and the arc grooves are rollingly connected, so that the sliding friction between the movable plate and the inner wall of the supporting leg is converted into rolling friction, thereby reducing the resistance of the movable plate sliding on the supporting leg, making it easier for the staff to drive the movable plate to rise and fall through the lifting assembly.

[0017] Furthermore, a rubber sheet is fixed to the side wall of the mounting seat.

[0018] By adopting the above technical solution, the rubber sheet is made of rubber material, which is elastic. After the support legs are folded, they cooperate with the side walls of the mounting seat and press against the rubber sheet, thereby reducing the wear between the support legs and the mounting seat.

[0019] Furthermore, a plurality of connecting rods are fixed to the side wall of the base, and an annular rod is commonly fixed to one end of the plurality of connecting rods away from the base.

[0020] By adopting the above technical solution, the setting of the connecting rod and the annular rod provides a fulcrum for the base, making it convenient for the staff to push the auxiliary device by holding the annular rod.

[0021] In summary, the utility model has the following beneficial effects:

[0022] 1. In this application, when the surveying and mapping equipment needs to be moved, the staff will retract the support legs and limit the support legs through the limit assembly, and then drive the moving plate downward through the lifting assembly, so that the support rod drives the universal wheel to contact the ground downward and lift the support legs, thereby moving the base and the surveying and mapping equipment through the universal wheel, eliminating the laborious operation of manually carrying the surveying and mapping equipment, and facilitating the movement of the surveying and mapping equipment;

[0023] 2. In this application, when the movable plate needs to be raised or lowered, the staff rotates the threaded rod through the star-shaped handle.

The universal wheel 5 is a universal wheel 5 commonly used in the prior art and applicable to this embodiment, and the universal wheel 5 is fixed to the lower end of the support rod 4.

[0032] A plurality of groups of lifting assemblies 6 are provided. The plurality of groups of lifting assemblies 6 are respectively installed on the plurality of support legs 2 and are used to lift the moving plate 3. Each group of lifting assemblies 6 includes a mounting plate 61, a threaded rod 62, and a star handle 63. The mounting plate 61 is in a rectangular plate shape and is fixed to the side wall of the support leg 2. The threaded rod 62 is in a rod shape, the threaded rod 62 penetrates through the mounting plate 61 and is threadedly connected, and the lower end of the threaded rod 62 is rotatably connected to the upper surface of the moving plate 3. The star handle 63 is fixed to the upper end of the threaded rod 62, and the axis of the star handle 63 coincides with the axis of the threaded rod 62.

[0033] The mounting seat 7 is a rectangular parallelepiped structure, and the mounting seat 7 is fixed to the bottom of the base 1. The limiting assembly 8 is installed on the mounting seat 7, and is used to limit the support leg 2. The limiting assembly 8 is provided with multiple groups, and each group of limiting assemblies 8 includes a fixed block 81, a limiting rod 82 and a pulling block 83. The fixing block 81 is a rectangular parallelepiped structure, and the fixing block 81 is fixed on the side wall of the mounting seat 7.
