Description

Technical Field

[0001] This utility model relates to the field of surveying equipment support technology, and in particular to a support for bridge engineering surveying equipment. Background Technology

[0002] Bridge engineering refers to the processes of bridge surveying, design, construction, maintenance, and inspection, as well as the science and engineering technology that studies these processes. It is a branch of civil engineering. The development of bridge engineering is mainly driven by the needs of transportation. When surveying bridge projects, scaffolding is needed to support the surveying equipment.

[0003] For example, the bracket for a bridge engineering surveying equipment disclosed in Chinese Patent No. CN217003740U works as follows: "The bracket is made of a positioning plate, a knob, a main screw, a main gear, a secondary gear, a secondary screw, a screw block, a crank rod, a clamping plate, and the surveying equipment body. The main screw drives the main gear to rotate, and the main gear drives the secondary screw to rotate through the secondary gear. The main screw and the secondary screw drive the two screws to move, thereby driving the two clamping plates to clamp the surveying equipment body on the positioning plate for fixation. When disassembling, the knob can be turned in the opposite direction to remove it. This avoids the problem of using bolts to fix the surveying equipment, which wastes a lot of effort when it is necessary to remove the equipment from the bracket, affecting the progress of disassembly and installation. It improves the ease of use of the device and reduces the difficulty of installation and disassembly."

[0004] This patent uses the rotation of a screw to fix the surveying equipment to the crank and clamp. Bridge surveys are usually conducted outdoors, where they are often exposed to the sun for extended periods. This causes the surveying equipment on the support to generate a lot of heat that cannot be dissipated in time. The heat sink of the surveying equipment itself may not be sufficient, which can lead to damage to the electronic components inside the surveying equipment due to operating in a high-temperature environment.

The upper end of the limiting mechanism is engaged with the inner cavity of the lower end face of the rotating plate, and a heat dissipation fixing mechanism for fixing and dissipating heat for the surveying equipment is engaged on the upper end face of the rotating plate.

[0006] As a preferred technical solution of this utility model, the heat dissipation fixing mechanism includes a slot, a movable fixing plate, a fan and a pipe.

[0019] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described herein without creative effort are all within the protection scope of this utility model. Unless otherwise specified, the experimental methods in the following embodiments are conventional methods, and the materials and reagents used in the following embodiments are commercially available unless otherwise specified.

[0020] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, this utility model provides a support for a bridge engineering surveying equipment, including a support plate 1, a support leg 2 installed at the lower end of the support plate 1, a rotating plate 3 rotatably connected to the upper end face of the support plate 1, and a limiting mechanism 4 opened on the left side face of the support plate 1. The upper end of the limiting mechanism 4 is engaged with the inner cavity of the lower end face of the rotating plate 3, and a heat dissipation fixing mechanism 5 for fixing and dissipating heat for the surveying equipment is engaged on the upper end face of the rotating plate 3.

[0021] Through the rotatable connection between the rotating plate 3 and the support plate 1, the rotating plate 3 can rotate, thereby driving the heat dissipation fixing mechanism 5 and the surveyor to rotate together, thereby increasing the survey range of the surveyor. When it rotates to the required position, the limiting mechanism 4 fixes the rotating plate 3, and then the heat dissipation fixing mechanism 5 fixes the surveyor and assists in its heat dissipation, preventing the heat generated by the surveyor when exposed to the sun outdoors from being unable to be effectively dissipated, thus playing an auxiliary protective role for the surveyor.

[0022] Specifically, the heat dissipation fixing mechanism 5 includes a slot 51, a movable fixing plate 52, a fan 54, and a pipe 55. The slot 51 is opened on the upper end face of the rotating plate 3. The outer wall of the lower end of the movable fixing plate 52 is engaged with the inner cavity of the slot 51. The fan 54 is fixedly connected to the inner wall of the lower end face of the rotating plate 3. The ends of the pipes 55 that are far apart from each other are connected to the ends of the movable fixing plate 52 that are close to each other, and the lower end of the pipes 55 is connected to the upper end face of the rotating plate 3.

[0023] When the fan 54 is started, air enters the inside of the pipe 55. The pipe 55 is a telescopic pipe, which allows the pipe 55 to move with the movable fixed plate 52. The cooling air enters the inside of the movable fixed plate 52 through the pipe 55 and is discharged through the cooling holes opened on the side of the movable fixed plate 52 that are close to each other, thereby providing auxiliary cooling for the surveyor.

[0024] Specifically, the inner wall of the movable fixing plate 52 is provided with a cooling air duct, and the side of the movable fixing plate 52 that is close to each other is provided with a cooling hole. The pipe 55 is a telescopic pipe. The inner cavity of the slot 51 is fixedly connected to the balance bar, and the outer wall of the balance bar is movably sleeved with the inner cavity at the lower end of the movable fixing plate 52.

[0025] When the fan 54 is started, the cooling air enters the fan 54 and the pipe 55 through the filter screen installed on the lower end face of the rotating plate 3, and then enters the cooling air duct inside the movable fixed plate 52. The air is then discharged through the cooling holes opened on the side of the movable fixed plate 52 that are close to each other, thereby providing auxiliary cooling for the surveyor.

[0026] Specifically, the heat dissipation fixing mechanism 5 includes a second spring 53, both ends of the second spring 53 are fixedly connected to one end of the movable fixing plate 52 that is close to each other, and the inner wall of the second spring 53 is movably sleeved with the outer wall of the limiting rod.

[0027] When the movable fixing plate 52 is used to fix the surveyor, the size of the surveyor causes the movable fixing plates 52 to move away from each other and stretch the second spring 53. The stretching of the second spring 53 causes the second spring 53 to generate a certain rebound force. The rebound force of the second spring 53 is used to drive the movable fixing plates 52 to move closer to each other and fix the surveyor.

[0028] Specifically, the limiting mechanism 4 includes a slide 41, a first spring 42, a lifting plate 43, and a fixing rod 44. The slide 41 is opened on the left side of the support plate 1. The lower end of the first spring 42 is fixedly connected to the lower end of the inner cavity of the slide 41. The outer wall of the lifting plate 43 is engaged with the inner cavity of the slide 41, and the lower end face of the lifting plate 43 is fixedly connected to the upper end of the first spring 42. A limiting rod is installed on the lower end face of the lifting plate 43 and is movably sleeved with the lower end face of the inner cavity of the slide 41. The lower end of the fixing rod 44 is fixedly connected to the upper end face of the lifting plate 43, and the upper end of the fixing rod 44 penetrates the upper end of the inner cavity of the slide 41 and is engaged with the inner cavity of the lower end face of the rotating plate 3.

[0029] Personnel move the lifting plate 43 downwards, causing the first spring 42 to compress and deform, which in turn moves the fixed rod 44 downwards. This causes the fixed rod 44 to lose its restraint on the rotating plate 3. Personnel then rotate the rotating plate 3, which in turn causes the heat dissipation fixing mechanism 5 and the surveyor to rotate. When the desired position is reached, personnel release the lifting plate 43, causing the lifting plate 43 to rise under the rebound force of the first spring 42, and restrain and fix the rotating plate 3 to prevent it from rotating. This increases the stability of the surveyor in bridge surveying.

[0030] Specifically, the support leg 2 is telescopic, and the lower end of the support leg 2 is tapered, and a fastening screw is fixedly connected to the surface of the support leg 2.

[0031] The support leg 2 is telescopic, so the bracket can be adjusted to different heights. The lower end of the support leg 2 is tapered, which allows the support leg 2 to be quickly inserted into the ground. The lower end of the support leg 2 is equipped with a fastening screw, which can be used to fix the support leg 2 after it is telescopic.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
