Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of tunnel construction, in particular to an arch frame docking auxiliary device and an arch frame gripper. Background Art
[0002] In tunnel support projects, it is a common support method to set up a layer of steel arch frames close to the inner surface in the tunnel. Due to the different cross-sectional sizes of the tunnels, for small-section tunnels, the arch frames can still be carried by a bench and manual labor to set up the arch for support, while for large-section tunnels, machine grippers have to be used to set up the arch. Since the cross-sectional area of the tunnel is relatively large, the arch frames used for support cannot be completely made into a whole arc that closely adheres to the inner surface of the tunnel. Therefore, the arch frames are divided into three or five or even more sections, and the connection between adjacent two sections is achieved by butt joint connection with bolts and flange plates.
[0003] However, the bolt connection between two arch frames is not a simple process. There are 4 hole positions on the common flange plate at the butt joint for inserting bolts and tightening nuts. Since the arch frame is relatively long, the two ends of the arch frame often tend to sag, and the flange plates at the two ends of the arch frame are very easy to shake, which undoubtedly increases the difficulty of the arch frame. 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 plate, and the corresponding bolts are also very difficult to be inserted and tightened.

[0043] Embodiment 1
[0044] As Figure 1 、 Figure 2Shown is an auxiliary device for arch frame docking disclosed in this embodiment, which includes a mounting base 1 and a support plate 2. A limiting rod 3 and a pin 4 are provided on the mounting base 1. A rib plate 5 is perpendicularly welded to the bottom of the support plate 2, and a strip-shaped through slot 501 is formed on the rib plate 5. Among them, the support plate 2 has a horizontal support state and a vertical storage state.
[0045] When the support plate 2 is in the horizontal support state, the limiting rod 3 abuts against the first end of the strip-shaped through slot 501, and the pin 4 abuts against the second end of the strip-shaped through slot 501. For example Figure 3 as shown, at this time, a mechanical limit lock is formed between the rib plate 5, the limiting rod 3 and the pin 4, so that the support plate 2 is fixed in Figure 3 the shown horizontal support state. Preferably, when the support plate 2 is in the horizontal support state, the end of the rib plate 5 also abuts against the mounting base 1 to prevent damage caused by excessive load on the limiting rod 3 and the pin 4 when the support plate 2 supports the arch frame.
[0046] When the support plate 2 is in the vertical storage state, the limiting rod 3 abuts against the second end of the strip-shaped through slot 501, and the pin 4 is separated from the strip-shaped through slot 501. That is, when the support plate 2 is not needed, first pull out the pin 4 from the second end of the strip-shaped through slot 501. At this time, due to the interference of the mounting base 1 on the rib plate 5, the support plate 2 cannot be rotated to the vertical storage state. Therefore, at this time, the support plate 2 can be translated parallel to the length of the strip-shaped through slot 501 so that the limiting rod 3 abuts against the second end of the strip-shaped through slot 501, thereby eliminating the interference of the mounting base 1 on the rib plate 5, and then the support plate 2 can be rotated around the limiting rod 3 to the vertical storage state, that is Figure 4 as shown.
[0047] It should be noted that although in this embodiment Figure 3 、 Figure 4 shown, the length direction of the strip-shaped through slot 501 is perpendicular to the support plate 2. However, in the specific application process, the length direction of the strip-shaped through slot 501 can also be set parallel to the support plate 2, for example Figure 5 、 Figure 6 as shown.
[0048] In this embodiment, the mounting base 1 is a U-shaped groove plate structure. The two ends of the limiting rod 3 are respectively connected to the two U-shaped side plates of the mounting base 1, and the pin 4 is detachably arranged on any one of the U-shaped side plates of the mounting base 1. Preferably, bushings 6 are provided on the inner walls of the two U-shaped side plates of the mounting base 1. The bushings 6 are sleeved on the limiting rod 3, and the rib plate 5 is located between the two bushings 6. The bushings 6 can not only protect the limiting rod 3, but also play a certain limiting role on the rib plate 5 to prevent the rib plate 5 from moving too much on the limiting rod 3.
[0049] As a preferred embodiment, a channel plate 7 is provided on the top of the pallet 2 for supporting and limiting the I-beam part of the arch support. The channel plate 7 is a U-shaped bent plate or composed of multiple plates welded together. The width of the I-beam of a common steel arch support is usually between 84 mm and 100 mm. Therefore, in this embodiment, the groove width of the channel plate 7 is set to 100 mm to 110 mm. In the working state, the I-beam part of the arch support to be docked is clamped in the groove of the channel plate 7 by operating the gripper, and the end flange of the arch support is placed on the pallet 2. At the same time, the gripper 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.
[0050] In the specific implementation process, the channel plate 7 can be directly fixed and welded to the pallet 2. Or the channel plate 7 can also be fixedly connected to the pallet 2 by countersunk head screws, so that it can be fastened without exposing the surface of the channel plate 7, avoiding interference with the I-beam part. At the same time, if it is necessary to adjust the height of the channel plate 7 on the pallet 2 during use, one or more shims can be directly added between the channel plate 7 and the pallet 2, so as to adapt to arch supports of different specifications.
[0051] In this embodiment, the pin 4 is an L-shaped pin. Refer to Figure 7 , the pin 4 includes a pin rod 401, a pin barrel 402 and a spring 403. The pin rod 401 is integrally L-shaped. The two ends of the pin barrel 402 are open and are fixed on any U-shaped side plate of the mounting seat 1 by welding or threaded connection. At the same time, there is an annular retaining ring 404 in the pin barrel 402. The spring 403 is located in the pin barrel 402, and its two ends respectively abut against the retaining ring 404 and the stepped structure on the first end of the pin rod 401. At the same time, there is a notch on the pin barrel 402 that can catch the second end of the pin rod 401. When the second end of the pin rod 401 is located in the notch, the spring 403 is in a relaxed state. At this time, the first end of the pin rod 401 extends out, so as to limit the rib plate 5, that is Figure 8 as shown. When the second end of the pin rod 401 is located at the end of the pin barrel 402, the spring 403 is in a compressed state. At this time, the first end of the pin rod 401 retracts, so as to separate from the rib plate 5, that is Figure 9 as shown.
[0052] Embodiment 2

During work, the end flange of the arch support 9 grabbed by the arch support gripper falls on the pallet 2, and then the arch support 9 is lifted, so that another arch support 9 to be docked falls on the pallet 2, that is Figure 10 as shown.
