Description

Technical Field

[0001] The utility model relates to the technical field of highway construction, in particular to a design and measurement device for highway construction. Background Art

[0002] Highway engineering refers to the survey, measurement, design, construction, maintenance, and management of highway structures. Highway engineering structures include: roadbed, pavement, bridges, culverts, tunnels, drainage systems, safety protection facilities, greening and traffic monitoring facilities, as well as houses, workshops, and other service facilities used for construction, maintenance, and monitoring. During the highway construction process, engineers need to measure data on the construction site when designing.

[0003] After searching the publication (announcement) number: CN212156489U, a highway design measurement device is disclosed, including a measurement device body, the bottom of the measurement device body is fixedly connected with a fixed seat, the bottom of the fixed seat is movably connected with a connecting plate, and both sides of the fixed seat are provided with movable grooves. The highway design measurement device fixes the fixed seat and the connecting plate by a U-shaped limit block, so that the installation is more convenient and stable, and the movable rod is limited by a pin rod to prevent it from shaking randomly during use. At this time, the length of the movable rod can be adjusted according to actual conditions, so that it is more convenient to use. The pin rod is taken out to separate the movable rod from the movable tube, and then the U-shaped limit block is pulled out from the inside of the slot to separate the fixed seat and the connecting plate, so that each component can be stored separately, making it more convenient to disassemble and store, and achieving the purpose of simple structure, easy disassembly and installation, and more convenient to carry.

[0004] Although the above scheme achieves the purpose of simple structure, easy disassembly and installation, and more convenient to carry, it cannot achieve multi-angle measurement of the same measuring point after a single fixation of the bracket during the measurement process. For this reason, we propose a design measurement device for highway construction. Utility Model Content

[0005] The main purpose of the utility model is to provide a design measurement device for highway construction, which solves the problem that multi-angle measurement of the same measurement point cannot be achieved after a single fixation of the bracket during the measurement process by setting an angle adjustment unit and an auxiliary unit.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A design and measurement device for highway construction, comprising a main unit, an angle adjustment unit arranged above the main unit, a telescopic unit arranged below the main unit, and an auxiliary unit arranged on the side of the telescopic unit;

[0008] The angle adjustment unit comprises a fixed plate installed on the top of the main unit, a rotating shaft movably installed on the inner bottom wall of the fixed plate, a gear plate installed on the side wall of the rotating shaft, and a clamping member arranged in the fixed plate;

[0009] The auxiliary unit includes a rotation slot at the bottom of the telescopic unit, a mounting seat movably arranged in the rotation slot, a threaded hole at the top of the mounting seat, a threaded rod movably arranged in the threaded hole, and a screwing handle installed on the top of the threaded rod.

[0010] Preferably, the main unit comprises a mounting plate, a connecting pipe movably mounted on the bottom of the mounting plate, and a measuring instrument body mounted on the top of the rotating shaft.

[0011] Preferably, the engaging member comprises a fixing plate and a fixing seat mounted on the inner side wall of the fixing disk, a locking plate movably mounted on the top of the fixing seat, and a return spring having one end fixedly connected to the fixing plate and the other end fixedly connected to the locking plate.

[0012] Preferably, the angle adjustment unit further includes an adjustment handle installed on a side wall of the rotating shaft.

[0013] Preferably, the telescopic unit comprises a movable rod movably arranged in the connecting tube, a plurality of matching holes opened on the side wall of the connecting tube and arranged at equal intervals, and a matching piece arranged on the movable rod.

[0014] Preferably, the matching component includes a receiving groove provided on the movable rod, a connecting spring installed in the receiving groove, and a telescopic column installed at the end of the connecting spring.

[0015] Compared with the prior art, the utility model has the following beneficial effects:

[0016] In the utility model, by providing an angle adjustment unit and an auxiliary unit, when it is necessary to measure multiple angles of the same measuring point, the adjusting handle is rotated so that the rotating shaft drives the gear plate to rotate. After the two side ends of the measuring instrument body are oriented toward the measuring angle, the clamping plate automatically clamps between two adjacent gear teeth of the gear plate under the elastic force of the return spring, thereby realizing multiple angle measurements of the same measuring point after the bracket is fixed once; when it is necessary to fix the bracket to the measuring point, after adjusting the total length between the connecting pipe and the movable rod, the mounting seat is rotated so that the threaded rod is perpendicular to the ground, and then the screwing handle can be rotated so that the screwing handle penetrates below the ground of the measuring point, thereby strengthening the fixation of the bracket and avoiding the deviation of the measuring device during the measurement process.
