Problems solved by technology

[0003] At present, in the process of tunnel construction, steel arches need to be erected on the excavated rock face. The traditional steel arches are heavy, and the installation of the arches is mainly carried out by manpower. It has the following disadvantages: 1. The number of workers required is large, and the labor intensity Large size and low efficiency. Existing arch frames are mostly connected by flanges and sleeves. When on-site installation requires a lot of manual construction; 2. Existing arch frames cannot match the mechanized on-site construction of arch frames
[0004] In order to solve the problems existing in the steel arches in the prior art, manipulators have gradually appeared in the arching operation. However, the current manipulators use the steel arch clamping equipment to hold several sections of the steel arch at the same time, and then Fixed connections such as welding are performed on the joints. Such operations also require more labor, and the safety cannot be guaranteed.
Therefore, with the development and progress of technology, foldable steel arches have gradually appeared. After the steel arches are installed and folded, they are transported to the tunnel for unfolding and erection operations, leaving a lot of operations on the steel arches. Outside the tunnel, it solves the time-consuming and labor-consuming problems of erecting steel arches in the existing tunnel construction
[0005] However, there is no good steel arch clamping device in the prior art to solve the problem of stable transportation and clamping of the folded steel arch in the tunnel.

Embodiment 1

[0042] The arch clamping device of the present invention is mainly suitable for folding arches, such as Figure 7 As shown, the folded arch frame is composed of multiple steel arch segments, and the adjacent arch segments are connected by hinges, as shown in Figure 7 As shown, the folding arch includes a middle section 201, a left section one 301, a left section two 302, a left section three 303, a right section one 401, a right section two 402 and a right section three 403; wherein, the left section two 302 and the left section After the three 303 are folded in half, they are folded into the left section one 301; after the right section two 402 and the right section three 403 are folded in half, they are folded into the right section one 401.

[0043] In order to clamp the above-mentioned arches conveniently, the present invention discloses a clamping device for steel arches, which includes an installation platform 8, an arch grabbing mechanism 1, an arch grabbing mechanism ...

Embodiment 2

[0068] A trolley for installing a steel arch, which includes the clamping device used for the steel arch in Embodiment 1; the clamping device is arranged on the trolley through an arm frame, and each side of the arm frame is provided with a Auxiliary jibs, two auxiliary jibs are provided with hanging baskets and / or arch auxiliary grippers and / or auxiliary hoisting mechanisms and / or rock wall breaking mechanisms.

[0069] In the above structure, during the unfolding process of the arch, the jib and the clamping device lift the entire folded arch, and then the auxiliary jib on the left side of the jib follows the left section 2 302 and the left section 3 303 to move, and the auxiliary left section 2 302 3. The left section three 303 is unfolded, and the auxiliary boom frame on the right side of the jib follows the right section two 402 and the right section three 403 to move, and the auxiliary right section two 402 and the right section three 403 are launched. The arch auxiliary...

Abstract

Disclosed is a clamping device for a steel arch frame. The clamping device for the steel arch frame comprises a mounting platform, an arch frame grabbing mechanism I, an arch frame grabbing mechanismII, an arch frame supporting mechanism I and an arch frame supporting mechanism II. The arch frame grabbing mechanism I and the arch frame grabbing mechanism II are located above the mounting platform. The arch frame grabbing mechanism I and the arch frame grabbing mechanism II are arranged on the mounting platform through a supporting frame I and a supporting frame II correspondingly. The mounting platform is located between the arch frame supporting mechanism I and an arch frame mounting mechanism II. The arch frame supporting mechanism I is arranged on the mounting platform through a horizontal telescopic mechanism I. The arch frame supporting mechanism II is arranged on the mounting platform through a horizontal telescopic mechanism II. The horizontal telescopic mechanism I and the horizontal telescopic mechanism II are used for driving the arch frame supporting mechanism I and the arch frame supporting mechanism II to move in the length direction of the mounting platform. By meansof the clamping device, a folded steel arch frame can be stably and reliably clamped, and the safety of transportation and erection of the folded steel arch frame in a tunnel is guaranteed.

Description

technical field [0001] The invention relates to the technical field of tunnel construction, in particular to a clamping device for a steel arch and a trolley for installing the steel arch. Background technique [0002] In recent years, my country's underground engineering has developed rapidly, and mechanized operations have gradually been widely used in engineering technology, especially in the field of underground tunnel construction. [0003] At present, in the process of tunnel construction, steel arches need to be erected on the excavated rock face. The traditional steel arches are heavy, and the installation of the arches is mainly carried out by manpower. It has the following disadvantages: 1. The number of workers required is large, and the labor intensity Large size and low efficiency. Existing arches are mostly connected by flanges and sleeves. When on-site installation requires a lot of manual construction; 2. Existing arch constructions cannot cooperate with mech...
