Description

Technical Field

[0001] The present application relates to the technical field of engineering surveying and mapping, and in particular to a surveying and mapping device for highway engineering cost. Background Art

[0002] A highway is a public road connecting two places, which allows people to travel quickly and improve travel efficiency. Before the construction of a highway, it is necessary to conduct surveying and mapping to determine the various parameters of the highway and the cost of the entire highway project. This process is generally carried out using surveying and mapping equipment.

[0003] At present, most surveying and mapping devices include an adjustable tripod and a surveying and mapping instrument. The surveying and mapping instrument can be placed stably by the tripod, so that surveying and mapping personnel can complete the surveying and mapping.

[0004] However, in actual surveying, the bottom of the tripod may be placed on soft ground (such as soil), hard ground (such as cement ground) or pothole ground. For soft ground and pothole ground, the bottom of the tripod is pointed and easy to place steadily. For hard ground, the bottom of the tripod is flat and easy to place steadily. However, the bottom of the tripod of most surveying devices has only one structure, which is not easy to apply to various ground forms. Based on this, the present application proposes a surveying device for highway engineering cost. Utility Model Content

[0031] The embodiment of the present application provides a highway engineering cost surveying and mapping device, such as Figure 1 and Figure 2 As shown, it includes a support plate 100, three upper support rods 300, three lower support rods 400, three base plates 500 and three tip plates 600, wherein the support plate 100 is used to support the surveying and mapping instrument 200, the upper support rods 300 and the lower support rods 400 form the basic structure of the tripod, and the base plate 500 and the tip plate 600 are respectively used for different ground forms.

[0032] like Figure 1 As shown, a surveying and mapping instrument 200 is provided on the support plate 100, and the surveying and mapping instrument 200 can realize the surveying and mapping of highway engineering.

[0033] like Figure 1 and Figure 3 As shown, the three upper support rods 300 are all rotatably connected to the edge of the support plate 100 and are evenly distributed to form the general structure of the tripod. The lower end of the upper support rod 300 is provided with an upper receiving groove 310, and the upper support rod 300 is provided with a plurality of upper through holes 320 spaced apart along its length direction. The upper through holes 320 are connected with the upper receiving groove 310 to form an adjustable installation structure.

[0034] like Figure 1 and Figure 4 As shown, three lower support rods 400 are slidably connected in the upper receiving groove 310 one by one, and a lower threaded hole 410 is provided at the upper end of the lower support rod 400. The lower threaded hole 410 can be opposite to any upper through hole 320 and fixed by bolts, thereby realizing the telescopic installation of the lower support rod 400 relative to the upper support rod 300, and the entire device can be adjusted.

[0035] like Figure 4 As shown, a lower receiving groove 420 is provided at the lower end of the lower support rod 400, and the lower support rod 400 is provided with two lower through holes 430 spaced apart along its length direction, and the lower through holes 430 are connected with the lower receiving groove 420 to form an adjustable installation structure.

[0036] like Figure 1 As shown, the three bottom plates 500 are rotatably connected to the lower ends of the three lower support rods 400 one by one, and the bottom plates 500 can be well placed on a hard ground, so that the entire device can be placed stably.

[0037] like Figure 2 and Figure 5 As shown, the lower end of the tip plate 600 forms a tip, and the three tip plates 600 are slidably connected in the lower receiving groove 420 one by one. The upper end of the tip plate 600 is provided with a tip threaded hole 610, and the tip threaded hole 610 can be opposite to any lower through hole 430 and fixed by bolts to achieve the installation of the tip plate 600 in the lower receiving groove 420.

[0038] like Figure 1 and Figure 2 As shown, the tip plate 600 has two installation positions. When the tip threaded hole 610 is opposite to the lower through hole 430 above, the tip plate 600 retracts into the lower receiving groove 420, which does not affect the rotation and placement of the bottom plate 500. When the tip threaded hole 610 is opposite to the lower through hole 430 below, the tip plate 600 extends out of the lower receiving groove 420, and the lower end of the tip plate 600 can be placed on a soft ground to achieve stable placement.

[0039] When in use, the upper support rod 300 and the lower support rod 400 cooperate to realize the adjustment function of the tripod. On a hard ground, the base plate 500 can be placed well. At this time, the tip plate 600 is retracted into the lower receiving groove 420 of the lower support rod 400 and fixed on the lower through hole 430 above, which does not affect the use of the base plate 500. On a soft ground, the tip plate 600 extends from the lower receiving groove 420 of the lower support rod 400 and is fixed on the lower through hole 430 below. The tip plate 600 can be well embedded in the soft ground to achieve placement. At this time, the base plate 500 can be rotated to one side without affecting the placement of the tip plate 600.

[0040] Compared with the prior art, the highway engineering cost surveying and mapping device can be stably placed on hard and soft ground through the two forms of the base plate 500 and the tip plate 600, thereby improving the application range of the entire device, being convenient to use and having strong practicality.

[0041] In some embodiments, Figure 3 and Figure 4 As shown, the upper receiving groove 310 and the lower receiving groove 420 are both rectangular grooves, and the cross-sectional shapes of the lower support rod 400 and the tip plate 600 are correspondingly rectangular, so that the lower support rod 400 does not rotate in the upper receiving groove 310 and the tip plate 600 does not rotate in the lower receiving groove 420, which facilitates sliding.

[0042] In some embodiments, the number of the upper through holes 320 is 8, so that the lower support rod 400 can be adjusted to 8 positions, with higher adjustment accuracy and convenient adjustment and use.

[0043] In some embodiments, the distance between two adjacent upper through holes 320 is 50 mm to 100 mm, and the distance adjusted each time is 50 mm to 100 mm, which facilitates adjusting the support plate 100 to a desired position.

[0044] In some embodiments, when the tip threaded hole 610 is opposite to the lower through hole 430 above, the lower end of the tip plate 600 is aligned with the lower end of the lower accommodating groove 420, so that when the tip plate 600 is just retracted into the lower accommodating groove 420, the tip threaded hole 610 is opposite to the lower through hole 430 above, making it convenient to install the tip plate 600 to the lower through hole 430 above.

[0045] In some embodiments, Figure 1 As shown, the lower surface of the base plate 500 is provided with a plurality of anti-skid protrusions 510, which may be made of rubber to increase the friction between the base plate 500 and the hard ground, thereby playing an anti-skid role and ensuring that the entire device is placed stably.

[0046] In some embodiments, the plurality of anti-skid protrusions 510 are spaced apart and distributed along the length direction of the bottom plate 500 , which is in accordance with the stress conditions of the bottom plate 500 and has a good anti-skid effect.

[0047] In some embodiments, Figure 6 As shown, a protective cover 110 is provided on the support plate 100, and the protective cover 110 is provided on the surveying and mapping instrument 200. On the one hand, the protective cover 110 can provide shade to prevent direct sunlight from shining on the surveying and mapping instrument 200, making it convenient to observe the data displayed by the surveying and mapping instrument 200; on the other hand, it can prevent rain to prevent the surveying and mapping instrument 200 from being exposed to rain, thereby reducing the possibility of damage.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, ordinary technicians in the field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
