Description

Technical Field

[0001] This utility model belongs to the field of tunnel measurement technology, specifically relating to a multifunctional folding frame for tunnel measurement. Background Technology

[0002] Tunnels are structures built underground, underwater, or in mountains to carry railways or highways for motor vehicles.

[0003] Based on their location, tunnels can be divided into three main categories: mountain tunnels, underwater tunnels, and urban tunnels. Mountain tunnels are those that pass under mountains or hills to shorten distances and avoid steep gradients; underwater tunnels pass under rivers or straits to cross them; and urban tunnels are those that pass underground in cities to accommodate railways passing through large cities. Tunnel engineering requires tunnel surveying, which involves the use of support frames. Traditional tunnel surveying support frames require individual connection and installation during use, and disassembly when not in use, consuming significant time and manpower, and are inconvenient to use. Therefore, we propose a multi-functional folding frame for tunnel surveying. Utility Model Content

Two corresponding strip grooves are formed on the upper side of the support frame. Support bars are installed inside the strip grooves, with one end of each support bar rotatably connected to the inside of the strip groove. A connecting groove is formed on the lower side of each support bar, with a connecting bar rotatably connected inside the connecting groove. Evenly distributed locking holes are formed inside the strip groove, with the lower side of each connecting bar locking into its corresponding locking hole. Fixing components are installed on the upper sides of the four support bars, thus supporting the two support plates.

[0008] Furthermore, the fixing assembly includes a support plate, slots, fixing blocks, a locking rod, a connecting plate, and a spring. The support plate is provided on the upper side of the support frame. The front and rear sides of the support plate are provided with evenly distributed slots. The fixing block is fixed on the upper side of the support bar. A sliding hole is provided in the middle of the fixing block. A locking rod is slidably connected inside the sliding hole. One end of the locking rod is fixed to the connecting plate. The end of the locking rod away from the connecting plate is engaged in the interior of the corresponding slot. A spring is sleeved on the circumferential surface of the locking rod. One end of the spring is fixed to the end face of the corresponding connecting plate. The other end of the spring is fixed to the side of the corresponding fixing block. The user can stand above the two support plates to measure the tunnel.

[0009] Furthermore, it also includes a connecting component, which includes an L-shaped groove and a U-shaped connecting plate. The side of the support plate has an L-shaped groove, and the U-shaped connecting plate is slidably connected inside the two L-shaped grooves. The two support plates are connected by setting the connecting component.

[0010] Furthermore, an anti-slip rubber frame is fixed to the lower side of the support frame, and the lower side of the anti-slip rubber frame is provided with evenly distributed anti-slip grooves. By setting the anti-slip rubber frame, the stability of the support frame can be effectively improved.

[0011] Furthermore, a fixing groove is provided on the upper side of the support plate, and a pad is fixed inside the fixing groove. By setting the pad, the stability of the support plate can be effectively improved.

[0012] Compared with the prior art, the beneficial effects achieved by this utility model are: This utility model,

[0013] By setting a fixing component, four levers can be pulled out to separate them from the slots on the front and back sides of the two support plates when not in use. After separation, the two support plates can be removed. After removal, the four connecting strips can be pulled out from the inside of the slots connected to them. After being pulled out, the four connecting strips can be folded into the inside of the four connecting slots. Then, the four support strips can be folded into the inside of the four strip slots. Then, the two support frames can be folded so that the anti-slip rubber frame on the lower side can be folded together. In this way, the folding is completed, effectively reducing the footprint.

[0014] By setting up a support assembly, the four support bars can be pulled out from the four connecting slots during use. After pulling them out, the angle of the four support bars can be adjusted, and then the lower ends of the four connecting bars can be inserted into the appropriate locking holes. Then, the two support plates can be pulled to adjust their overall length. After adjustment, they can be inserted between the four support plates. At this time, the four locking rods will enter into their corresponding locking slots under the action of the four springs, thus fixing the two support plates. After fixing, the user can stand on the upper side of the two support plates to measure the tunnel, which is extremely convenient. Attached Figure Description
