[0027] In order to help those skilled in the art better understand the present invention, the following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0028] As described in the background art, in traditional technology, the installation of steel arch frames mainly relies on workers to carry and position them by carrying them on their shoulders or by hand. This process is not only extremely labor-intensive and requires a lot of physical strength from workers, but also inefficient, which seriously affects the construction progress.

[0029] In order to solve this technical problem, the utility model provides a highway tunnel excavation steel arch frame installation auxiliary device, which is used to assist in the installation of the steel arch frame.

[0030] Specifically, please refer to Figure 1-Figure 3 The auxiliary devices for installing steel arch frames in highway tunnel excavation specifically include:

[0031] The moving mechanism 1 and the lifting mechanism 2, the top of the lifting mechanism 2 is provided with a support seat 3, the inner side of the support seat 3 is provided with a groove 301, the bottom of the inner cavity of the groove 301 is provided with a receiving groove 302, two connecting shafts 303 are installed between the groove 301 and the support seat 3, the outer surfaces of the two connecting shafts 303 are provided with support plates 304 through bearing sleeves, the two support plates 304 are fixedly connected to the side close to each other with a slide cylinder 305, and a bracket 306 is installed on the slide cylinder 305.

[0032] The utility model provides an auxiliary device for installing a steel arch frame for highway tunnel excavation. The bracket 306 provided in this application can support the steel arch frame. The setting of the moving mechanism 1 allows the entire device to be moved to transport and position the steel arch frame, which greatly reduces the physical burden on workers and improves work comfort and efficiency. The bracket 306 is pushed up by the slide cylinder 305, and then the steel arch frame is driven to rise to the installation position, so that the steel arch frame can be supported and positioned after installation.

[0033] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0034] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions therein can be combined with each other.

[0035] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0036] Example 1, please refer to Figure 1-Figure 3 The support frame 306 is pushed up by the sliding cylinder 305, and the steel arch frame is supported and positioned.

[0037] Further, such as Figure 3 As shown, the two support plates 304 are both inclined outward, and slopes are provided on the inner walls on both sides of the groove 301, and the slopes are in contact with the side of the support plate 304 away from the slide cylinder 305. This arrangement allows the support plate 304 to be supported and limited by the slope after it is rotated open to maintain the position of the support plate 304.

[0038] Further, such as Figure 3As shown, the accommodating groove 302 is used to accommodate the slide cylinder 305 after the support plate 304 is rotated to the horizontal. After use, the support plate 304 is rotated to the inside of the groove 301 to the horizontal. At this time, the slide cylinder 305 can be accommodated in the accommodating groove 302. The support seat 3 and the support plate 304 cooperate with each other to protect the slide cylinder 305, and the overall height is reduced to facilitate transportation.

[0039] Further, such as Figure 2 As shown, a notch 307 is provided on the outer side of the top of each of the two support plates 304. The notch 307 is provided to facilitate the staff to rotate and open the support plates 304 when the support plates 304 are in a horizontal state.

[0040] Example 2 further optimizes the highway tunnel excavation steel arch installation auxiliary device provided in Example 1. Specifically, Figure 1 As shown, the moving mechanism 1 includes a base frame 101, on which a plurality of moving wheels 102 are provided. The lifting mechanism 2 is installed between the top of the base frame 101 and the bottom of the support base 3. The setting of the moving wheels 102 facilitates the movement of the entire device.

[0041] Example 3 further optimizes the highway tunnel excavation steel arch installation auxiliary device provided in Example 1 or 2. Specifically, Figure 1 As shown, the lifting mechanism 2 includes two first columns 201 fixedly installed on the top of the base frame 101, and a slide groove 202 is provided on the side where the two first columns 201 are close to each other. The two slide grooves 202 are inserted with second columns 203. The top ends of the two second columns 203 respectively pass through the two slide grooves 202 and are fixedly connected to the support seat 3. This arrangement can support the support seat 3 and can adjust the height of the support seat 3.

[0042] Further, such as Figure 1 As shown, a reinforcement frame 207 is fixedly connected between the base frame 101 and the two first columns 201 . The reinforcement frame 207 is used to reinforce the first columns 201 to improve the firmness of the first columns 201 .

[0043] Further, such as Figure 1 As shown, a fixing piece is provided between the second column 203 and the reinforcement frame 207 , and the fixing piece is used to fix the second column 203 , thereby achieving the fixation of the height of the support base 3 .

[0044] Further, such as Figure 1As shown, the fixing part includes several limiting holes 205 opened on the second column 203, and a hand-tightening bolt 206 is provided on the outer side of the reinforcement frame 207. One end of the hand-tightening bolt 206 is inserted into one of the limiting holes 205. By inserting the hand-tightening bolt 206 into the limiting hole 205, the position of the second column 203 can be fixed. After loosening the hand-tightening bolt 206 so that the hand-tightening bolt 206 is separated from the limiting hole 205, the second column 203 can be pushed up and down to adjust the height of the support seat 3.

[0045] Further, such as Figure 1 As shown, a reinforcement plate 204 is fixedly connected between the bottoms of the two second columns 203 , and the reinforcement plate 204 is used to reinforce the space between the two second columns 203 .

[0046] The use process of the auxiliary device for installing the steel arch frame for highway tunnel excavation provided by the utility model is as follows:

[0047] After the adjustment is completed, screw the hand-tightening bolt 206 so that the hand-tightening bolt 206 is plugged into the corresponding limiting hole 205, and the steel arch frame is placed between the two brackets 306. The device drives the steel arch frame to the installation position, and then the slide cylinder 305 pushes the bracket 306 to rise, so that the steel arch frame rises to the installation position. After the steel arch frame is installed, the slide cylinder 305 drives the bracket 306 to descend, so that the bracket 306 is separated from the steel arch frame; after use, rotate the support plate 304 toward the inside of the groove 301 so that the slide cylinder 305 is accommodated in the accommodating groove 302, that is, Figure 4 As shown, when using again, just press the support plate 304 from the notch 307 with your finger to open it.
