Description

Technical Field

[0001] The utility model relates to the technical field of tunnel construction, in particular to an auxiliary bracket for arch and an arch gripper. Background Technique

[0002] In tunnel support projects, it is a common support method to set up a layer of steel arches close to the inner surface in the tunnel. Due to the different cross-sectional sizes of the tunnels, the tunnels with small cross-sections can still rely on the scaffolding and manual handling of the arches to set up the arches for support, while the tunnels with large cross-sections have to rely on machine grippers to set up the arches. Since the cross-sectional area of the tunnel is relatively large, the arches used for support cannot be completely made into a complete arc that closely adheres to the inner surface of the tunnel. Therefore, the arches will be divided into three parts or five parts or even more. The connection between adjacent two sections is then connected by bolts and flange plates.

[0003] However, the bolt connection between two sections of arches is not a simple process. There are 4 hole positions on the common flange plate at the docking part for inserting bolts and tightening nuts. Since the arches are relatively long, the ends of the arches often tend to sag, and the flange plates at both ends of the arches are very easy to shake, which undoubtedly increases the difficulty of installing the arches. Due to the lack of the flexibility of human hands, it is very difficult for the machine gripper to stably and accurately align the hole positions at the flange plates, and the corresponding bolts are also very difficult to be inserted and tightened. Content of the Utility Model

[0004] Aiming at the above deficiencies in the prior art, the utility model provides an auxiliary bracket for arch and an arch gripper, which can quickly make the arch enter the established track, quickly dock with the hole positions at the flange plates, and has the advantages of simple structure, convenient operation, safety and reliability, and low cost.

[0045] Embodiment 1

[0046] As Figure 1 、 Figure 2 shown, a buttress auxiliary bracket disclosed in this embodiment mainly includes a mounting seat 1, a support plate 2, and a channel plate 3. The support plate 2 is connected to one end of the mounting seat 1, and the other end of the mounting seat 1 is used to connect to external components such as an arch grab for fixing or assembling the buttress auxiliary bracket.

[0047] The channel plate 3 is a U-shaped bent plate or composed of multiple plates welded together. The channel plate 3 is fixedly arranged on the top of the first end of the support plate 2 to support and limit the I-beam part of the arch frame. The top of the second end of the support plate 2 is a support portion 201 for supporting the end flange of the arch frame. Specifically, the width of the I-beam of a commonly used steel arch frame is usually between 84 mm and 100 mm. Therefore, the groove width of the channel plate 3 in this embodiment is set to be between 100 mm and 110 mm. In the working state, by operating the grab, the I-beam part of the arch frame to be butt-jointed is clamped in the groove of the channel plate 3, and at the same time, the grab is operated to lift upwards, which not only restricts the swaying of the end flange and the I-beam part but also can solve the problem of the downward deflection of the I-beam part by lifting.

[0048] Through holes 202 are respectively provided on both sides of the middle of the support plate 2. When the end flanges of two sections of the arch frame are butted but offset, a crowbar can be passed through the through holes 202 and used as a fulcrum to pry the arch frame for more delicate hole position adjustment. Preferably, convex plates extending outwards are respectively provided on both sides of the middle of the support plate 2, and the through holes 202 are provided on the corresponding convex plates, that is, the width of the support plate 2 corresponding to the support portion 201 is smaller than the width corresponding to the through holes 202, thereby forming a notch at the butt joint of the end flanges to facilitate the staff to more conveniently observe the hole alignment situation during the process of prying the arch frame.

[0049] In the specific implementation process, the channel plate 3 can be directly fixedly welded to the support plate 2. Or the channel plate 3 can also be fixedly connected to the support plate 2 through countersunk head screws, so that it can be tightened without exposing the surface of the channel plate 3, avoiding interference with the I-beam part. At the same time, if it is necessary to adjust the height of the channel plate 3 on the support plate 2 during use, one or more shims can be directly added between the channel plate 3 and the support plate 2, thereby adapting to different specifications of arch frames.

[0050] As a preferred embodiment, the pallet 2 is hinged to the mounting seat 1, and an attitude adjustment mechanism is provided between the pallet 2 and the mounting seat 1 for fixing the pallet 2 in a horizontal support state or switching it to a vertical storage state. When it is necessary to support the arch frame, the pallet 2 is fixed in the horizontal support state. When it is not necessary to support the arch frame, the pallet 2 is switched to the vertical storage state.

[0051] Specifically, the attitude adjustment mechanism includes a pin shaft 4, a rib plate 5, and a plug pin 6. The mounting seat 1 is of a U-shaped groove plate structure. The two ends of the pin shaft 4 are respectively connected to the two side plates of the mounting seat 1, and the plug pin 6 is detachably arranged on any one of the side plates of the mounting seat 1. The rib plate 5 is vertically arranged at the bottom of the pallet 2 by welding, and a strip-shaped through groove 501 is formed on the rib plate 5. At the same time, the pin shaft 4 passes through the strip-shaped through groove 501.

[0052] When the pallet 2 is in the horizontal support state, the pin shaft 4 abuts against the first end of the strip-shaped through groove 501, and the plug pin 6 abuts against the second end of the strip-shaped through groove 501. At this time, a mechanical limit lock is formed between the rib plate 5, the pin shaft 4, and the plug pin 6, so that the pallet 2 is fixed in Figure 3 the shown horizontal support state. Preferably, when the pallet 2 is in the horizontal support state, the end of the rib plate 5 also abuts against the U-shaped end plate of the mounting seat 1 to prevent damage to the pin shaft 4 and the plug pin 6 due to excessive load when the pallet 2 supports the arch frame.

[0053] When the pallet 2 is in the vertical storage state, the pin shaft 4 abuts against the second end of the strip-shaped through groove 501, and the plug pin 6 is separated from the strip-shaped through groove 501. That is, when the pallet 2 is not needed, first pull out the plug pin 6 from the second end of the strip-shaped through groove 501. At this time, due to the interference of the mounting seat 1 on the rib plate 5, the pallet 2 cannot be rotated to the vertical storage state. Therefore, at this time, the pallet 2 can be translated parallel to the length of the strip-shaped through groove 501, so that the pin shaft 4 abuts against the second end of the strip-shaped through groove 501, thereby eliminating the interference of the mounting seat 1 on the rib plate 5, and the pallet 2 can be rotated around the pin shaft 4 to the vertical storage state, that is Figure 4 as shown.

[0054] It should be noted that although in this embodiment Figure 3 、 Figure 4 the length direction of the strip-shaped through groove 501 shown is perpendicular to the pallet 2. However, in the specific application process, the length direction of the strip-shaped through groove 501 can also be set parallel to the pallet 2, for example Figure 5 、 Figure 6 as shown.

[0055] In the specific implementation process, bushings 7 are provided on the inner walls of the two side plates of the mounting seat 1. The bushings 7 are sleeved on the pin shaft 4, and the rib plate 5 is located between the two bushings 7. The bushings 7 can not only protect the pin shaft 4, but also play a certain limiting role on the rib plate 5 to prevent the rib plate 5 from moving too much on the pin shaft 4.

[0056] In this embodiment, the latch 6 is an L-shaped pin. Refer to Figure 7 , the latch 6 includes a latch rod 601, a latch cylinder 602 and a spring 603. The latch rod 601 is integrally L-shaped. Both ends of the latch cylinder 602 are open and are fixed on any side plate of the mounting seat 1 by welding or threaded connection. At the same time, an annular retaining ring 604 is provided inside the latch cylinder 602. The spring 603 is located inside the latch cylinder 602, and both ends thereof abut against the retaining ring 604 and the step structure on the first end of the latch rod 601 respectively. At the same time, a notch for catching the second end of the latch rod 601 is provided on the latch cylinder 602. When the second end of the latch rod 601 is located in the notch, the spring 603 is in a relaxed state. At this time, the first end of the latch rod 601 extends out, thereby limiting the rib plate 5, that is Figure 8 as shown. When the second end of the latch rod 601 is located at the end of the latch cylinder 602, the spring 603 is in a compressed state. At this time, the first end of the latch rod 601 retracts, thereby separating from the rib plate 5, that is Figure 9 as shown.
