DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0022] like Figure 1 - Figure 4 As shown, the portable municipal engineering surveying and mapping device of the utility model comprises a surveying and mapping instrument 1 and a tripod 2. The surveying and mapping instrument 1 is mounted on the top of the tripod 2 for surveying and mapping. The tripod 2 comprises a mounting seat 21 and three telescopic leg assemblies 22. The top surface of the mounting seat 21 is used to mount the surveying and mapping instrument 1. The upper ends of the three telescopic leg assemblies 22 are rotatably arranged on the mounting seat 21, and the lower ends are used to support on the ground.

[0023] Figure 1 and Figure 3 As shown, each telescopic leg assembly 22 includes a primary support tube 221 and a secondary support tube 222. The upper end of the primary support tube 221 is hingedly mounted on the mounting seat 21, and the secondary support tube 222 is slidably disposed in the primary support tube 221 and can be telescoped as needed. A first stopper 223 is disposed on the primary support tube 221 to limit the position of the secondary support tube 222, thereby fixing its length.

[0024] A mounting head 224 is disposed on the top of the primary support tube 221, and hinge shafts 225 are disposed on both sides of the mounting head 224. A hinge seat 211 is disposed at the bottom of the mounting seat 21, and a hinge hole 212 is disposed on the hinge seat 211. The hinge shaft 225 is rotatably disposed in the hinge hole 212, so that the primary support tube 221 can rotate relative to the mounting seat 21 at a certain angle.

[0025] The hinge seat 211 is also provided with a deformation gap portion 213, which is connected with the hinge hole 212. By adjusting the adjustment bolt 214 provided on the hinge seat 211, the deformation of the deformation gap portion 213 can be controlled, and then the damping of the hinge hole 212 can be adjusted, thereby controlling the resistance of the primary support tube 221 to rotate relative to the mounting seat 21.

[0026] like Figure 3 As shown, the first limiting member 223 includes a first limiting bolt, and a first mounting sleeve 2211 is provided at the lower end of the first-level support tube 221. The first limiting bolt is provided on the first mounting sleeve 2211. By rotating the first limiting bolt, it can be abutted against the outer wall of the second-level support tube 222, thereby limiting the position of the second-level support tube 222 in the first-level support tube 221 and fixing its length.

[0027] like Figure 3 As shown, the secondary support tube 222 includes a first support tube 2221 and a second support tube 2222. The first support tube 2221 is slidably disposed on the primary support tube 221, and the second support tube 2222 is slidably disposed in the first support tube 2221. A second stopper 2223 is disposed at the lower end of the first support tube 2221, which is used to limit the position of the second support tube 2222 in the first support tube 2221. A plug-in portion 2224 is disposed at the lower end of the second support tube 2222, which is used to be plugged into the ground or other supports to provide stable support.

[0028] The structure of the second limiting member 2223 is similar to that of the first limiting member 223, and includes a second limiting bolt. A second mounting sleeve 2225 is disposed at the lower end of the first support tube 2221, and the second limiting bolt is disposed on the second mounting sleeve 2225. By rotating the second limiting bolt, the second limiting bolt can be abutted against the outer wall of the second support tube 2222, thereby limiting the position of the second support tube 2222 in the first support tube 2221 and fixing its length.

[0029] like Figure 1 and Figure 4As shown, the positioning assembly includes a positioning plate 3, a first bolt 31 and a second bolt 32, and the first bolt 31 and the second bolt 32 are arranged at intervals on the first mounting sleeve 2211 of the primary support tube 221. One end of the positioning plate 3 is hinged on the first bolt 31, and the other end is provided with a clamping groove 33, which is used to clamp on the second bolt 32 arranged on the first mounting sleeve 2211 of the adjacent primary support tube 221, so as to fix the three telescopic leg assemblies 22 together and maintain the stability of the tripod 2.

[0030] The upper part of the primary support tube 221 is provided with a third bolt 2212, and the third bolt 2212 matches the design of the positioning plate 3. The end of the positioning plate 3 close to the clamping groove 33 is provided with a receiving groove 34, and the shape and size of the receiving groove 34 match the third bolt 2212. When the positioning plate 3 needs to be stored, it is only necessary to rotate the positioning plate 3 to a position parallel to the primary support tube 221, and then align the receiving groove 34 with the third bolt 2212, and clamp one end of the positioning plate 3 on the third bolt 2212, and the storage can be completed.

[0031] Working principle:

[0032] When using the portable municipal engineering surveying and mapping device of the utility model, first adjust the length of the telescopic leg assembly 22 according to actual needs, and fix the length of the primary support tube 221 and the secondary support tube 222 by rotating the first limit bolt and the second limit bolt, so as to adapt to the ground height and terrain requirements.

[0033] Next, install the surveying instrument 1 on the top surface of the mounting base 21, and perform necessary calibration and settings. Then, unfold the tripod 2 and place it at the location to be surveyed, ensure that the plug-in portion 2224 of the telescopic leg assembly 22 is stably inserted into the ground or other supports to provide stable support, and then fix the tripod through the positioning plate. Finally, start the surveying instrument 1 to carry out surveying work. Since the surveying device of the utility model adopts a retractable and foldable design, the entire device is lighter and more convenient to carry. When not in use, the telescopic leg assembly 22 can be retracted to the shortest state, and the positioning plate 3 can be stored on the primary support tube 221. Then, fold the entire device, and use the handle or other carrying device at the bottom of the mounting base 21 to conveniently carry the surveying device to the location where it is needed.

[0034] The portable municipal engineering surveying and mapping device of the utility model adopts a retractable and foldable design, which solves the problems of large size, heavy weight and inconvenient carrying of traditional surveying and mapping devices. At the same time, by setting the first limiter and the second limiter, the length of the telescopic leg assembly can be easily adjusted and its position can be fixed. By setting the positioning assembly, the stability of the tripod can be maintained. The surveying and mapping device of the utility model has the advantages of simple structure, convenient operation, and light carrying, and is suitable for wide use in municipal engineering construction.

[0035] Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field belong to the protection scope of the utility model.
