Description

Technical Field

[0001] The utility model relates to the technical field of tunnels, in particular to an arch mounting device with a breaker hammer and a tunnel construction vehicle. Background Art

[0002] Existing arch frame installation vehicles used in tunnel arch frame construction mostly adopt a mechanical arm grabber device to grab the arch frame through the grabber. However, during the tunnel construction process, the tunnel surrounding rock is often under-excavated due to uneven blasting. It is necessary to manually crush the under-excavated rock with an electric drill or use a breaker hammer or rock saw to crush it to achieve the construction of the arch frame fitting the inner wall of the tunnel. However, there are problems such as long secondary construction time, high cost, and high labor intensity.

[0003] Therefore, the current existing technology has proposed a method of integrating a mechanical arm gripper and a breaker hammer into one, such as the utility model patent disclosed in patent publication number CN212596245U, which is an arch gripper device with a crushing mechanism. The breaker hammer is installed inside the gripper device, thereby improving construction efficiency. However, in the specific application process, the opening and closing of the gripper requires a cylinder drive. In the past, the gripper device that was not equipped with a breaker hammer had enough space inside to accommodate the cylinder, so that it could drive the gripper while also being well protected from external impacts, falling objects, etc. and causing damage to it. However, after the breaker hammer is installed, the breaker hammer is relatively large, so the cylinder can only be placed at the bottom of the gripper device. Although the cylinder can be protected to a certain extent during the arch installation process, the entire device will inevitably need to be flipped over during the crushing process. At this time, the cylinder at the bottom will be exposed to the outside and face the risk of damage. Utility Model Content

[0006] The base frame is provided with arch grips at positions near both ends, and the top of the base frame and positions adjacent to the arch grips are provided with concave grooves;

[0007] An oil cylinder capable of driving the adjacent arch frame grips to open and close is provided in the sinking groove, and an oil cylinder guard plate corresponding to the groove is provided on the top of the base frame, and the oil cylinder guard plate covers the oil cylinder in the corresponding groove.

[0008] In one embodiment, an alignment auxiliary mechanism is provided at the end of the base frame to achieve positioning and alignment during the docking process of the two arch frames.

[0009] In one embodiment, the alignment assist mechanism includes a support plate and a grooved plate with a top expanded outward;

[0010] The support plate is connected to the end of the base frame, and the channel plate is arranged on the top of the support plate to support the end flange of the arch frame.

[0011] In one embodiment, the support plate is hinged or detachably connected to the end of the base frame, that is, the alignment assisting mechanism is foldable or detachable at the end of the base frame.

[0034] This embodiment discloses an arch frame installation device with a breaker hammer, which is mainly used to realize the integration of arch frame installation and under-break breaking while maintaining good protection for the gripper cylinder to avoid damage.

[0035] Example 1

[0036] like Figure 1 、 Figure 2As shown, this embodiment discloses an arch frame installation device with a breaker hammer, which mainly includes a base frame 1, an arch frame gripper 2 and a breaker hammer 3. The breaker hammer 3 is arranged inside the base frame 1, and the drill rod 301 of the breaker hammer 3 extends from the first end of the base frame 1 for performing crushing operations. The number of the arch frame grippers 2 is more than two, and each arch frame gripper 2 is distributed on the base frame 1 and close to the two ends of the base frame 1. At the same time, the top of the base frame 1 and the positions adjacent to the arch frame grippers 2 are respectively provided with concave sinks 101, and the sinks 101 are respectively provided with oil cylinders 4 that can drive the adjacent arch frame grippers 2 to open and close. At the same time, the top of the base frame 1 is provided with oil cylinder guards 5, and the oil cylinder guards 5 correspond to the sinks 101 one by one, and the oil cylinder guards 5 cover the oil cylinders 4 in the corresponding sinks 101.

[0037] It is worth noting that although Figure 1 The illustrated embodiment shows an arch gripper 2 at each end of the base frame 1. However, the present invention is not limited thereto. Alternatively, one oil cylinder 4 may be disposed at one end of the base frame 1 and two or more oil cylinders 4 may be disposed at the other end, or two or more oil cylinders 4 may be disposed at both ends of the base frame 1, depending on actual needs. Furthermore, a wider sink 101 may be disposed between two adjacent arch grippers 2 located at the same end of the base frame 1, so that the oil cylinders 4 of the two adjacent arch grippers 2 share the same sink 101. Alternatively, each of the two adjacent arch grippers 2 may use its own sink 101.

[0038] refer to Figure 1 、 Figure 2 As can be seen, the cylinder 4 at the first end of the base frame 1 is necessarily located between the breaker 3 and the cylinder guard 5. When the breaker 3 is shorter, the cylinder 4 at the second end of the base frame 1 is placed directly inside the base frame 1. When the breaker 3 is longer, the cylinder 4 at the second end of the base frame 1 can also be placed between the breaker 3 and the cylinder guard 5. In other words, in either case, the cylinder 4 on the arch mounting device is never exposed. This allows for integrated arch mounting and undercut crushing while maintaining good protection for the cylinder 4, preventing damage from external impacts or falling objects.

[0039] In this embodiment, the base frame 1 comprises a top plate and two side plates. The side plates are spaced parallel to each other and fixedly connected by a number of connecting posts. The top plate is fixedly connected to the tops of the two side plates. Notches are provided on the top edges of the two side plates at locations corresponding to the recesses 101. The ends of the top plate do not extend beyond the notches. The main body of the breaker 3 is fixedly connected between the two side plates by bolts.

[0040] In this embodiment, the arch gripper 2 includes claw fingers 201 symmetrically connected to either side of the base frame 1, namely, two claw fingers 201 are connected to the two side panels. Ear seats 102 are welded to the outer walls of the side panels. The claw fingers 201 are hingedly connected to the ear seats 102 via a first hinge 6. The two claw fingers 201 are hingedly connected to the ends of the cylinder 4 via a second hinge 7, with the first hinge 6 located below the second hinge 7.

[0041] Preferably, a protrusion 202 is provided on the side of the claw finger 201 facing the side plate, and the side plate is located on the rotation path of the protrusion 202, that is, when the arch frame gripper 2 is clamped, the protrusion 202 will first contact the side plate, which plays a role in limiting the movement position of the arch frame gripper 2, avoiding misalignment when the arch frame gripper 2 is clamped, that is, Figure 3 shown.

[0042] Further preferably, a protective cover 203 is detachably provided on the top of the claw finger 201 to protect the arch gripper 2.

[0043] In a specific implementation process, at least one arch support 8 is further provided on the top of the base frame 1 to support the arch during the arch installation process.

[0044] Example 2

[0045] like Figure 4 、 Figure 5 As shown, this embodiment discloses an arch mounting device with a breaker hammer, and its implementation is basically the same as that of Example 1, with the only difference being:

[0046] In this embodiment, the first end and / or the second end of the upper base 1 of the arch mounting device is provided with an alignment auxiliary mechanism to achieve positioning and alignment during the docking process of the two arches.

[0047] In this embodiment, the alignment assist mechanism includes a support plate 9 and a trough plate 10 with an outwardly flared top. The support plate 9 is connected to the first and / or second ends of the base frame 1. The trough plate 10 is welded or bolted to the top of the support plate 9 to support the end flanges of the arch. The trough plate 10, by supporting the end flanges of the arch, effectively prevents the arch from buckling and shaking during installation. The outwardly flared top trough plate 10 also serves to limit the end flanges of the arch, allowing for rapid alignment of the bolt holes on the end flanges of the two arches during installation.

[0048] In a specific implementation, the support plate 9 can be hingedly connected to the end of the base frame 1 or detachably connected. When the support plate 9 is detachably connected to the end of the base frame 1, the support plate 9 can be directly fixed to the end of the base frame 1 with bolts. When the arch mounting device does not require the use of an alignment assist mechanism, the alignment assist mechanism can be directly removed. When the support plate 9 is hingedly connected to the end of the base frame 1, one end of the support plate 9 is rotatably connected to the end of the base frame 1. At the same time, a removable limit rod can be arranged at the end of the base frame 1. When the limit rod is not withdrawn, the support plate 9 is supported in a horizontal state. When the limit rod is withdrawn, the support plate 9 can be flipped downward and folded.

[0049] Furthermore, it is also possible to use Figure 6 The structure shown enables the support plate 9 to be folded. Figure 6 The support plate 9 includes a support plate 9, a groove plate 10, and a mounting seat 11 welded or bolted to the end of the base frame 1. A limit rod 12 and a latch 13 are provided on the mounting seat 11. A rib 14 is vertically welded to the bottom of the support plate 9, and the rib 14 has a strip-shaped through-slot 15. The support plate 9 has a horizontal support state and a vertical storage state. When the support plate 9 is in the horizontal support state, the limit rod 12 abuts against the first end of the strip-shaped through-slot 15, and the latch 13 abuts against the second end of the strip-shaped through-slot 15. At this time, a mechanical limit is formed between the rib 14 and the limit rod 12 and the latch 13, so that the support plate 9 is fixed in the horizontal support state. Preferably, when the support plate 9 is in the horizontal support state, the end of the rib 14 also abuts against the mounting seat 11 to prevent the limit rod 12 and the latch 13 from being damaged due to excessive load when the support plate 9 supports the arch. When the support plate 9 is in the vertically stored position, the limiting rod 12 abuts the second end of the strip groove 15, and the latch 13 is separated from the strip groove 15. That is, when the support plate 9 is no longer needed, the latch 13 is first pulled out of the second end of the strip groove 15. At this time, due to the interference of the mounting seat 11 with the rib 14, the support plate 9 cannot be rotated to the vertically stored position. Therefore, the support plate 9 can be translated parallel to the length of the strip groove 15 so that the limiting rod 12 abuts the second end of the strip groove 15, thereby eliminating the interference of the mounting seat 11 with the rib 14, and the support plate 9 can be rotated about the limiting rod 12 to the vertically stored position.
