Description

Technical Field

[0001] This utility model relates to the technical field of three-arm arch frame installation trolleys, and in particular to an arch frame clamping and crushing mechanism and a three-arm arch frame installation trolley. Background Technology

[0002] During tunnel construction, the arch frame, anchor bolts, steel mesh, connecting steel bars, and concrete form a rigid body, creating a support surface to prevent tunnel collapse. Traditionally, arch frame installation was primarily manual, requiring a large workforce and posing a significant safety risk in the event of an accident. The use of a three-arm arch frame installation trolley can reduce the number of workers to 3-4 and significantly shorten construction time.

[0003] Currently, three-arm arch frame installation trolleys are frequently used in tunnel and underground engineering. Before arch frame installation, if under-excavation is found at the tunnel face after blasting, the trolley operates a crushing device to address this. Afterward, the trolley clamps the arch frame on the ground using an arch frame clamping mechanism. The boom then extends to the appropriate construction position, where workers stand within the work platform to connect and install multiple arch frame sections. However, existing arch frame clamping mechanisms, when used to clamp the arch frame to the installation position, may encounter under-excavated areas that affect installation. Therefore, the three-arm arch frame installation trolley must first lower the arch frame, then drive the under-excavation crushing mechanism to address the under-excavated areas, and finally clamp the arch frame again using the clamping mechanism for installation. This process is inconvenient and reduces construction efficiency.

[0004] Therefore, it is necessary to design an arch frame clamping and crushing mechanism and a three-arm arch frame installation trolley, which can clamp the arch frame to be installed and arrive at the installation position. If an under-excavated area is found, it can be dealt with in a timely manner, thereby improving construction efficiency. Utility Model Content

[0005] To address the problems in the prior art, this application proposes an arch frame clamping and crushing mechanism and a three-arm arch frame installation trolley, which can clamp the arch frame to be installed and, when it is found that there are areas under-excavated, promptly address those areas, thereby improving construction efficiency.

[0006] One aspect of this utility model provides an arch frame clamping and crushing mechanism, which includes a clamping base frame. At least two sets of clamping components are provided on the clamping base frame. Each clamping component cooperates with the other to clamp the arch frame. A crushing component is installed on the clamping base frame, which can process the under-excavated parts.

[0007] As a further improvement to the above technical solution:

[0008] Furthermore, in the aforementioned arch frame clamping crushing mechanism, the clamping base frame is a tubular structure, the crushing component is installed inside the clamping base frame, and the crushing end of the crushing component can extend out from the end of the clamping base frame.

[0009] The aforementioned arch frame clamping crushing mechanism further includes a crushing component comprising a crushing hammer, which is fixedly installed inside the clamping base frame by bolts.

[0010] The aforementioned arch frame clamping and crushing mechanism further includes a clamping assembly comprising a mounting bracket mounted on the clamping base frame. Both ends of the mounting bracket are hinged to gripping arms, and a gripping telescopic drive is hinged across the driving ends of the two gripping arms. The extension of the gripping telescopic drive can drive the clamping ends of the two gripping arms to move closer to each other to clamp the arch frame.

[0011] Furthermore, in the aforementioned arch frame clamping crushing mechanism, a limiting member is provided on the mounting bracket on the side of the gripper arm away from the clamping base frame, the limiting member being used to limit the opening angle of the gripper arm.

[0012] Furthermore, in the aforementioned arch frame clamping crushing mechanism, a limiting plate is installed on the clamping base frame. The limiting plate is used to limit the arch frame clamped by the clamping end of the grab arm.

[0013] In the aforementioned arch frame clamping and crushing mechanism, the limiting plate is provided with two spaced vertical plates, and the arch frame clamped by the clamping end of the grab arm is limited between the two vertical plates.

[0014] In the aforementioned arch frame clamping crushing mechanism, the limiting plate is further fixedly installed on the clamping base frame by bolts.

[0015] Furthermore, in the aforementioned arch frame clamping and crushing mechanism, a mounting seat is provided on the side of the clamping base away from the limiting plate, and the clamping base can be mounted on the arch frame position adjustment mechanism of the three-arm arch frame mounting trolley via the mounting seat.

[0016] Another aspect of this utility model provides a three-arm arch frame installation trolley, which includes the arch frame clamping and crushing mechanism as described above.

[0017] The above-mentioned technical features can be combined in various suitable ways or replaced by equivalent technical features, as long as the purpose of this utility model can be achieved.

[0018] This utility model provides an arch frame clamping and crushing mechanism and a three-arm arch frame installation trolley, which, compared with the prior art, have at least the following advantages: When the clamping components work together to clamp the arch frame and reach the installation position, if an under-excavation area is found, the crushing component is used to treat the under-excavated area before the clamped arch frame is installed in the installation position. This arch frame clamping and crushing mechanism can promptly treat the under-excavated area when it is found after clamping the arch frame to be installed and reaching the installation position, thereby improving construction efficiency.

[0031] The present invention will be further described below with reference to the accompanying drawings.

[0032] This utility model embodiment provides an arch frame clamping and crushing mechanism 100, which can clamp the arch frame to be installed and, when it is found that there is an under-excavation area, promptly handle the under-excavation area, thereby improving construction efficiency.

[0033] Please see Figure 1 The arch frame clamping and crushing mechanism 100 provided in this embodiment of the utility model includes a clamping base 110, at least two sets of clamping components 120 are provided on the clamping base 110, and each clamping component 120 cooperates with each other to clamp the arch frame. A crushing component 130 is installed on the clamping base 110, and the crushing component 130 can process the under-excavated parts.

[0034] When the clamping components 120 cooperate to clamp the arch frame to the installation position and find that there is an area that is under-excavated, the crushing component 130 is used to process the under-excavated area, and then the clamped arch frame is installed in the installation position. The arch frame clamping and crushing mechanism 100 provided in this embodiment of the utility model can promptly process the under-excavated area when it is found to be under-excavated after clamping the arch frame to be installed to the installation position, thereby improving construction efficiency.

[0035] The arch frame clamping and crushing mechanism 100 provided in this embodiment of the utility model is detailed in the following document. Figure 1 The clamping base 110 has a tubular structure, and the crushing component 130 is installed inside the clamping base 110, with the crushing end of the crushing component 130 extending out from the end of the clamping base 110. In this embodiment, the crushing component 130 includes a breaker hammer, which is fixedly installed inside the clamping base 110 by bolts. Of course, it is understood that the clamping base 110 can also be other structures, such as a trough structure, in which the crushing component 130 is installed; the crushing component 130 can also be other crushing components, such as a cone crusher.

[0036] The arch frame clamping and crushing mechanism 100 provided in this embodiment of the utility model is detailed in the following document. Figure 1 The clamping assembly 120 includes a mounting bracket 121, which is mounted on the clamping base 110. Both ends of the mounting bracket 121 are hinged with gripping arms 122. A gripping telescopic drive 123 is hinged across the driving ends of the two gripping arms 122. The extension of the gripping telescopic drive 123 can drive the clamping ends of the two gripping arms 122 to move closer to each other to clamp the arch frame. When it is necessary to clamp the arch frame to be installed, firstly, the gripping telescopic drive 123 retracts to drive the clamping ends of the two gripping arms 122 to move away from each other. Then, the arch frame is driven to clamp the crushing mechanism 100 and move closer to the arch frame to be installed, until the arch frame to be installed is located between the clamping ends of the two gripping arms 122. Then, the gripping telescopic drive 123 extends to drive the clamping ends of the two gripping arms 122 to move closer to each other to clamp the arch frame. Finally, the arch frame is driven to clamp the crushing mechanism 100 to the installation position for arch frame installation. After installation, the gripping telescopic drive 123 retracts to drive the clamping ends of the two gripping arms 122 to move away from each other to release the arch frame.

[0037] Further, please refer to Figure 1 A limiting member 124 is provided on the side of the gripper arm 122 away from the clamping base 110 on the mounting bracket 121. The limiting member 124 is used to limit the opening angle of the gripper arm 122. In this embodiment, the limiting member 124 is a limiting pin. The gripper extension drive 123 retracts to drive the clamping ends of the two gripper arms 122 away from each other until the gripper arm 122 abuts against the limiting pin, ensuring that the gripper arm 122 does not exceed the maximum opening position.

[0038] The arch frame clamping and crushing mechanism 100 provided in this embodiment of the utility model, further please refer to... Figure 1 A limiting plate 125 is installed on the clamping base 110. The limiting plate 125 is used to limit the placement of the arch frame held by the clamping end of the gripping arm 122. When the arch frame is clamped and grasped by the crushing mechanism 100, the arch frame held by the clamping end of the gripping arm 122 is limited to the limiting plate 125, which can limit the position of the arch frame and prevent the position of the arch frame from changing during grasping, thereby affecting the grasping stability. Specifically, the limiting plate 125 has two spaced vertical plates 126. The arch frame held by the clamping end of the gripping arm 122 is limited between the two vertical plates 126, and the vertical plates 126 on both sides prevent the arch frame from swinging left and right. In this embodiment, there are two limiting plates 125. The arch frame is arc-shaped, and the two ends of the inner side of the arc are respectively limited and contacted by one of the limiting plates 125. The limiting plate 125 is fixedly installed on the clamping base 110 by bolts. Of course, it is understandable that the limiting plate 125 can also be fixedly installed on the clamping base 110 in other ways, such as by buckles.

[0039] The arch frame clamping and crushing mechanism 100 provided in this embodiment of the utility model, further please refer to... Figure 1 A mounting base 111 is provided on the side of the clamping base 110 away from the limiting plate 125. The clamping base 110 can be mounted on the arch position adjustment mechanism of the three-arm arch frame installation trolley through the mounting base 111.

[0040] This utility model embodiment also proposes a three-arm arch frame installation trolley, which has the arch frame clamping and crushing mechanism 100 provided in any of the above embodiments. The specific structure of the arch frame clamping and crushing mechanism 100 is as described in the above embodiments. Since this three-arm arch frame installation trolley adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.
