Description

Technical Field

[0001] The utility model relates to the technical field of laser rangefinders, in particular to a measuring device for road and bridge design. Background Art

[0002] A laser rangefinder is an instrument that uses laser technology to measure distance. It calculates the distance between the target object and the rangefinder by emitting a beam of laser and measuring the time it takes for the laser to return. Laser rangefinders usually have the characteristics of high precision, fast measurement, and long-distance measurement. They are widely used in various fields such as construction, geographic surveying and mapping, industrial manufacturing, and military fields. The use of laser rangefinders can improve the accuracy and efficiency of measurements and is one of the important tools in modern measurement technology.

[0003] The existing related technologies often have the following defects: in the process of measuring roads and bridges, it is necessary to measure the length and span of the bridge, and a laser rangefinder is needed to measure the length and span of the bridge. Before using the laser rangefinder, a brick is usually placed under the laser rangefinder to raise the laser rangefinder to avoid the influence of debris on the bridge deck on the laser rangefinder. However, the height of bricks and other products is limited, and the required height adjustment of the laser rangefinder cannot be achieved, thereby reducing the use effect of the laser rangefinder.

[0004] Therefore, the utility model provides a measuring device for road and bridge design. Utility Model Content

[0029] The specific arrangement and function of the supporting device 4 and the cleaning device 5 will be described in detail below.

[0030] Reference Figure 1-Figure 3 As shown, in this embodiment: the supporting device 4 includes a bottom frame 402, the bottom frame 402 is a step structure, a telescopic tube 401 is fixedly installed on the upper end of the bottom frame 402, the telescopic tube 401 is a folding structure, a fixed plate 403 is fixedly installed on the upper end of the telescopic tube 401, a circular plate 406 is rotatably connected to the upper surface of the fixed plate 403, two limit blocks 411 are fixedly installed on the upper surface of the circular plate 406, the inside of the two limit blocks 411 is rotatably connected to a rotating shaft frame 413, a rotating block 412 is fixedly connected to the side wall of the rotating shaft frame 413, the upper end of the rotating block 412 is fixedly connected to the laser rangefinder 1, and the bottom frame 402 is a hollow structure. The water will flow into the inside of the telescopic tube 401, so that the water can be injected. The telescopic tube 401 will be stretched after the water is injected. The bottom frame 402 of the ladder structure is placed on the ground, which can improve the stability of the laser rangefinder 1 after being placed. The stretched telescopic tube 401 can lift the laser rangefinder 1 to a certain height. The side wall of the rotating shaft frame 413 is threadedly connected with a bolt 414. The rotating bolt 414 is pressed against the side wall of the limit block 411 to achieve the fixing of the rotating laser rangefinder 1.

[0031] The side wall of the bottom frame 402 is connected to a water injection pipe 404, and the upper end of the water injection pipe 404 is threadedly connected with a screw cover 405. First open the screw cover 405, and water can be injected into the water injection pipe 404. The lower surface of the bottom frame 402 is fixedly connected with an anti-skid pad 410. By providing the anti-skid pad 410, the stability of supporting and placing the laser rangefinder 1 is also increased. The side wall of the bottom frame 402 is fixedly connected with a first fixed block 407, the side wall of the fixed plate 403 is fixedly connected with a second fixed block 409, and the upper surface of the first fixed block 407 is fixedly connected with a slide bar 408, and the slide bar 408 is slidably connected to the inside of the second fixed block 409. The slide bar 408 slides inside the second fixed block 409, which plays a role in limiting the extension direction of the telescopic tube 401.

[0032] Reference Figure 1-Figure 2 and Figure 4As shown, specifically, the cleaning device 5 includes a hose 51 connected to the fixed plate 403, the other end of the hose 51 is fixedly connected to a threaded head 55, the side wall of the threaded head 55 is threadedly connected to a connection box 54, a plurality of reserved holes 57 are evenly opened on the surface of the connection box 54, and a sponge block 53 is glued to the surface of the connection box 54. After the threaded head 55 inside the connection box 54 is rotated and the threaded head 55 is lifted a little from the bottom wall of the connection box 54, water can flow into the inside of the connection box 54 along the hose 51, and then the sponge block 53 can be soaked along the through hole. At this time, the soaked sponge block 53 can be used to wipe the display 2, thereby improving the use effect of the display 2. The outer sides of the connection box 54 and the sponge block 53 are covered with a cotton cloth cover 52, and the end side of the threaded head 55 is glued with a rubber ring 56. By providing a replaceable cotton cloth cover 52, the wiping effect of the display 2 is further improved. By rotating the threaded head 55 against the bottom wall of the connecting box 54, the water flow can be blocked. The provision of the rubber ring 56 improves the tightness of the water blockage.

[0033] Working principle: when it is necessary to adjust the use height of the laser rangefinder 1, first open the screw cover 405 and inject water into the water injection pipe 404. The water will flow into the telescopic tube 401, so that the water injection work can be realized. The telescopic tube 401 will stretch after the water is injected. The bottom frame 402 of the ladder structure is placed on the ground, which can improve the stability of the laser rangefinder 1 after being placed. The stretched telescopic tube 401 can lift the laser rangefinder 1 to a certain height. The extension height adjustment work of the telescopic tube 401 can be controlled by adjusting the amount of water injected into the telescopic tube 401, which facilitates the support work of the laser rangefinder 1 at different heights. The sliding rod 408 slides inside the second fixed block 409, which plays a role in limiting the extension direction of the telescopic tube 401, avoiding the telescopic tube 401 from tilting during use. The rotating block 412 on the two rotating shaft frames 413 can be rotated to adjust the irradiation angle of the laser rangefinder 1. After adjusting the appropriate angle, the bolt 414 can be rotated to squeeze the side wall of the limit block 411, so as to realize the fixing work of the rotating laser rangefinder 1. The rotating circular plate 406 facilitates the irradiation and ranging work of buildings in different positions. By setting the anti-slip pad 410, the stability of supporting and placing the laser rangefinder 1 is also increased. By adding water, the gravity of placing the laser rangefinder 1 can be increased, and the stability of placing the laser rangefinder 1 on the ground is improved. The water inside the telescopic tube 401 can be squeezed out to realize the contraction of the telescopic tube 401, which can reduce the carrying space and weight of the supporting device 4, and facilitate the overall carrying work of the laser rangefinder 1 and the supporting device 4 in the later stage. By setting the supporting device 4, the flexible support work of the laser rangefinder 1 is facilitated. On the premise of increasing the stability of the placement of the laser rangefinder 1, the adjustment of the placement height of the laser rangefinder 1 is also facilitated, thereby improving the use effect of the laser rangefinder 1.

[0034] By rotating the threaded head 55 inside the connection box 54 and lifting the threaded head 55 a little from the bottom wall of the connection box 54, water can flow into the interior of the connection box 54 along the hose 51, and then the sponge block 53 can be soaked along the through hole. At this time, the soaked sponge block 53 and the cotton cloth cover 52 can be used to wipe the display 2, which improves the use effect of the display 2. By providing a replaceable cotton cloth cover 52, the wiping effect of the display 2 is further improved. By rotating the threaded head 55 to abut against the bottom wall of the connection box 54, the flow of water can be blocked. The setting of the rubber ring 56 improves the tightness of the water blockage. By providing the cleaning device 5, the flexible use of water is facilitated, thereby facilitating the flexible wiping and cleaning of the display 2, and improving the utilization rate of the water inside the telescopic tube 401.
