DETAILED DESCRIPTION

[0036] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0037] Embodiment 1

[0038] See also Figure 1 , Figure 2 and Figure 3 This embodiment provides a technical solution: a support frame for laser radar surveying and mapping, including a support seat 1, a transmission part 2 and a support part 3:

[0039] A connecting disk 101 is provided at the bottom end of the support seat 1, and a plurality of rotating grooves are provided around the connecting disk 101. The transmission part 2 is provided inside the support seat 1, and the screw rod 201 is rotatably provided inside the support seat 1. The driven bevel gear 202 is provided at the top of the screw rod 201, and a transmission bevel gear 203 meshingly connected with the driven bevel gear 202 is provided next to the driven bevel gear 202. A thread groove is provided at the center of the transmission disk 205, and the screw rod 201 passes through the thread groove and is threadedly connected thereto. Three support parts 3 are provided, and the bottoms of the three support parts 3 are triangular in design, which increases the stability of the support parts 3 when supporting. The three support parts 3 are rotatably provided around the support seat 1, and the support The top of the rod 301 is embedded in the rotating groove and is rotationally connected to the support seat 1. The bottom of the support rod 301 is provided with a support foot 303, which allows the support rod 301 to rotate and unfold along the rotating groove. The side of the support rod 301 is rotationally connected with a transmission rod a302. A plurality of rotating grooves are provided around the transmission disk 205. One end of the transmission rod a302 is embedded in the rotating groove and is rotationally connected to the transmission disk 205. The transmission rod a302 rotates on the transmission disk 205 along the rotating groove to change the angle. The rotation of the transmission bevel gear 203 drives the screw rod 201 to rotate, thereby driving the transmission disk 205 to move up and down, driving the transmission rod a302 to rotate, and pushing the support rod 301 to rotate and unfold.

[0040] The side of the support rod 301 is rotatably connected to the transmission rod a302 in an articulated manner, forming a structure in which the side of the middle part of the support rod 301 is articulated to the transmission rod a302.

[0041] The screw rod 201 is rotatably arranged inside the support seat 1, that is, the screw rod 201 can be rotatably connected to the connecting plate 101 by means of a bearing, that is, a hole slightly larger than the diameter of the screw rod 201 is opened on the connecting plate 101, and a bearing is installed in the hole to achieve cooperation with the screw rod 201. The inner and outer rings of the bearing are respectively fixed on the screw rod 201 and the connecting plate 101, allowing the screw rod 201 to rotate smoothly.

[0042] The support portion 3 adopts a triangular bottom design, which can ensure that the support frame stands firmly under different terrain conditions and maintains good balance even on uneven ground, thereby improving the stability and load-bearing capacity of the entire system, and is conducive to protecting expensive laser radar equipment from vibration or tipping risks. At the same time, through the threaded connection between the lead screw 201 and the transmission disk 205, the transmission bevel gear 203 and the driven bevel gear 202 are meshed to achieve precise up and down movement of the transmission disk. Through this sophisticated and efficient method, the user only needs to rotate the transmission device (such as a crank) to drive the support rod 301 to expand or retract around the support seat 1, which simplifies the operation process and makes the deployment and storage of the equipment quick and convenient.

[0043] Embodiment 2

[0044] See also Figure 1 , Figure 2 and Figure 3 , this embodiment provides a technical solution: a support frame for laser radar surveying and mapping, including a transmission part 2, a driven bevel gear 202 and a transmission bevel gear 203:

[0045] A screw rod 201 is provided for internal rotation of the support seat 1, and the screw rod 201 passes through the connecting plate 101 and is rotatably connected thereto, a driven bevel gear 202 is provided at the top of the screw rod 201, and a crank 204 is provided at one end of the transmission bevel gear 203, and the crank 204 passes through the support seat 1 and is rotatably connected thereto, and the transmission bevel gear 203 is driven to rotate inside the support seat 1 by turning the crank 204, thereby allowing the transmission bevel gear 203 to drive the driven bevel gear 202 to rotate, so that the screw rod 201 rotates inside the support seat 1.

[0046] This design realizes precise mechanical transmission through the cooperation of the screw rod 201, the driven bevel gear 202 and the transmission bevel gear 203. When the operator rotates the crank 204, the transmission bevel gear 203 rotates accordingly, thereby driving the driven bevel gear 202 meshing therewith to rotate, and finally causing the screw rod 201 to rotate precisely inside the support seat 1. This solution enables the height of the support frame or other adjustable parts to be fine-tuned, which is more suitable for laser radar mapping work that requires high-precision positioning.

[0047] The design of the crank 204 adopted in this solution allows the user to easily adjust the position of the support frame without tools. The height adjustment and other operations can be completed by manually rotating the crank, which greatly improves the convenience of use and reduces the difficulty and time cost of operation.

[0048] The transmission method of the screw rod 201 and the bevel gear is adopted here, which is more durable than other transmission methods (such as belts or chains), reduces wear and tear, and ensures stability and accuracy in long-term use. In addition, this mechanical structure usually has a high load-bearing capacity, which can ensure the stable installation of the laser radar under various operating conditions. And this scheme integrates the main transmission components inside the support seat 1, which not only makes the external structure more concise, but also helps to reduce the floor space, improve portability and storage efficiency, and is particularly suitable for field operations or environments with limited space. And because the main transmission components are enclosed in the support seat, it can effectively prevent external factors such as dust and rain from eroding the internal mechanical structure, reduce the maintenance frequency, and facilitate regular inspection and maintenance.

[0049] Embodiment 3

[0050] See also Figure 1 , Figure 4 and Figure 5 This embodiment provides a technical solution: a support frame for laser radar surveying and mapping, including a support seat 1 and a protective part 4:

[0051] There are three protective parts 4, which are hinged on the top of the support base 1. The protective part 4 includes a protective rod 401 whose bottom is rotatably connected to the support base 1, a transmission rod b402 rotatably connected to the protective rod 401, and a protective cover 403 arranged on the top of the protective rod 401. The bottom of the protective rod 401 is embedded in a plurality of rotating grooves opened around the connecting disk 101 and is rotatably connected to it. One end of the transmission rod b402 is embedded in a plurality of rotating grooves opened around the transmission disk 205 and is rotatably connected to it. The three protective covers 403 are rotated to fit each other to form a cylindrical protective shell. The laser radar body 5 is located inside the three protective covers 403. The transmission disk 205 drives the transmission rod b402 to rotate when moving, so that the transmission rod b402 drives the protective rod 401 to rotate. The three protective covers 403 are combined to form a closed cover body, which wraps or covers the laser radar body 5, thereby protecting the laser radar body 5 and avoiding collision and damage to the laser radar body 5 during the transportation of the support frame.

[0052] This solution achieves instant protection of the laser radar body by integrating the protection function directly into the supporting structure. When the equipment needs to be moved or stored, the protective cover 403 can be quickly closed without additional operation, which greatly simplifies the protection process and reduces potential human errors. In addition, the cooperation of the transmission bevel gear and the screw rod realizes the efficient conversion from simple rotation action to complex protection action, which not only saves space, but also improves the response speed and reliability of the system, ensuring that the protective cover can accurately wrap the radar body and effectively prevent external physical damage.

[0053] The above solution rotatably sets the protective part on the top of the support base, and integrates the transmission mechanism with the support base, thereby avoiding the problem that the traditional protective cover needs to be disassembled and assembled separately, reducing the user's carrying burden and improving the convenience of use.

[0054] Embodiment 4

[0055] See also Figure 1 , Figure 2 and Figure 3 This embodiment provides a technical solution: a laser radar, including the above-mentioned laser radar surveying and mapping support frame, the laser radar also includes a laser radar body, the laser radar body is arranged on the top of the support seat, when the three protective covers are rotated to the top of the support seat, they are closed to form a closed cover body, and the closed cover body covers the laser radar body.

[0056] Working principle: First, when the support frame is unfolded and used, the transmission bevel gear 203 is driven to rotate inside the support seat 1 by turning the crank 204, so that the transmission bevel gear 203 drives the driven bevel gear 202 to rotate, so that the screw rod 201 rotates inside the support seat 1, thereby controlling the transmission disc 205 to move downward. During the downward movement of the transmission disc 205, the transmission disc 205 drives the transmission rod a302 to rotate, so that the transmission rod a302 pushes the support rod 301 to rotate, so that it can be unfolded. At the same time, when the transmission disc 205 moves, it will also drive The transmission rod b402 rotates, so that the transmission rod b402 drives the protective rod 401 to rotate, allowing the three protective covers 403 to open, revealing the internal laser radar body 5, and then completing the surveying operation through the laser radar body 5, and then rotating the crank handle 204 in the opposite direction to retract and store the three support rods 301, and allow the three protective covers 403 to wrap up the laser radar body 5 after merging, thereby protecting the laser radar body 5 and avoiding collision and damage to the laser radar body 5 during the transportation of the support frame.
