Problems solved by technology

However, when the tripod is placed on a hard ground such as concrete, the fixed feet cannot be clamped into the ground, so the tripod can only rely on the friction between the fixed angle toes and the ground and the damping at the hinge to maintain stability
When the measurement time is long, the three supporting feet are easy to slide to the outside, causing the surveying and mapping instrument to drop, affecting the accuracy of surveying and mapping, which needs to be improved

Embodiment 1

[0041] A kind of tripod for engineering supervision, such as figure 1 As shown, it includes a mounting platform 1 for fixing surveying and mapping instruments. The mounting platform 1 is triangular in shape and has length-adjustable legs 2 hinged on each side below.

[0042] like figure 1 , figure 2As shown, two adjacent legs 2 are connected by a fixing device 3. The fixing device 3 includes a fixed block 31 fixedly connected with the legs 2. The fixed block 31 is fixedly connected with a rotating rod 32, and the rotating rod 32 is connected with a connecting bar 33 in rotation. . The ends of two adjacent connecting bars 33 away from the rotating rod 32 are jointly pierced with fixing bolts 34 . The connecting bars 33 can rotate around the axis of the fixing bolts 34 , so that the included angle between the two connecting bars 33 can be changed, so that the supporting foot 2 can rotate relative to the mounting table 1 .

[0043] like figure 2 , image 3 As shown, the h...

Embodiment 2

[0051] like Figure 7 , Figure 8 As shown, the difference from the first embodiment is that the support part 26 includes a connection plate 41 for fixed connection with the connection sleeve 6 . The side of the connecting plate 41 away from the sliding plate 25 is fixedly connected to the first hinged seat 42 , the first hinged seat 42 is hinged to the second hinged seat 44 via the hinged shaft 43 , and the second hinged seat 44 is fixedly connected to the flat plate 45 . The hinge axis 43 axis is parallel to the rotation axis 53 between the leg 2 and the installation platform 1, so when the leg 2 is opened, the second hinge seat 44 rotates around the hinge axis 43 and the plate 45 can fully contact with the ground. The contact area between the support part 26 and the ground is relatively large, and heavy objects can be placed on the flat plate 45, so the friction force between the ground and the support part 26 increases, and the supporting feet 2 are prevented from being s...

Embodiment 3

[0053] like Figure 9 , Figure 10 As shown, the difference from the first embodiment is that the support part 26 includes a support plate 51 for fixed connection with the connecting sleeve 6 , and a first rotating seat 52 is fixedly connected to the side of the support plate 51 away from the sliding plate 25 . The first rotating base 52 is hinged to the second rotating base 54 through the rotating shaft 53 , the second rotating base 54 is fixedly connected with a fitting plate 55 , and the four sides of the fitting plate 55 are fixedly connected with clamping plates 56 toward the direction away from the sliding plate 25 . The axis line of the rotating shaft 53 is parallel to the rotating shaft 53 between the supporting leg 2 and the mounting table 1, so when the supporting leg 2 is opened, the second rotating base 54 rotates around the rotating shaft 53 and the bonding plate 55 can be parallel to the ground surface. When the surveying and mapping instrument needs to be erect...

Abstract

The invention discloses a tripod for engineering supervision. According to the technical scheme, the tripod comprises a mounting table, wherein three supporting legs with adjustable lengths are hingedto the lower side of the mounting table, and every two adjacent supporting legs are connected through fixing device; the fixing devices comprise fixing blocks connected with the supporting legs, thefixing blocks are rotationally connected with connecting strips through rotating rods, fixing bolts penetrate through one ends, away from the rotating rods, of every two adjacent connecting strips, the fixing bolts are in threaded connection with fixing nuts, and holes for the connecting strips to allow the fixing bolts to penetrate through are connecting holes. When a surveying and mapping instrument is erected, after the supporting legs are opened and the initial leveling is completed, the two connecting strips are difficult to rotate around the axis of the fixing bolts, so that the positions of the two fixing blocks are relatively fixed, and the positions of the two adjacent supporting legs are relatively fixed. According to the tripod, the trouble that the surveying and mapping instrument is descended due to the fact that the supporting legs slide on the outer side for a long time can be avoided, and the accuracy of measurement is ensured.

Description

technical field [0001] The invention relates to a tripod, in particular to a tripod for engineering supervision. Background technique [0002] Surveying and mapping instruments such as total stations and levels are often used in the project supervision process, and the surveying and mapping instruments often need to be placed on a tripod for people to operate. A common tripod includes a mounting table for installing surveying and mapping instruments, and three legs are hinged on the lower side of the mounting table. According to the different terrain, adjust the length of the three legs so that the upper side of the installation platform is basically level, then install the surveying and mapping instrument on the installation platform, and then adjust the foot screw to make the surveying and mapping instrument accurately level. [0003] The Chinese patent with the publication number CN105805510B discloses a surveying and mapping instrument tripod, which includes an instrume...
