Description

Technical Field

[0001] The utility model relates to the technical field of tunnel gravel transmission, in particular to a V-shaped transmission component for preventing side leakage of water-carrying gravel. Background Art

[0002] As we all know, in the process of underground tunnel construction, shield machines are used to excavate underground soil or rock layers, and the excavated gravel is transmitted to the surface by transmission components. However, because the shield machine needs to use water to cool the cutter head during the excavation process, the excavated gravel contains water, so there are certain requirements for the transmission components.

[0003] At present, the gravel excavated by the shield machine is transported on a conveyor belt made of waterproof material. The conveyor belt is designed to be V-shaped so that it has a trough of a certain depth. The gravel with water is thrown into it and can be well transported. Then, during the operation of the conveyor belt, there will be vibration, and the gravel will carry accumulated water during the transmission process. After the vibration occurs, the gravel or muddy water will easily splash to the outside, which will affect the excavated area. In addition, because the shield machine needs to dismantle the transmission component after the excavation is completed, that is, when the gravel does not need to be transported, it is necessary to design a transmission component to solve the above problems. Utility Model Content

[0004] In view of the deficiencies in the above-mentioned prior art, the purpose of the present utility model is to provide a V-shaped transmission component which has a shock-absorbing effect, prevents side leakage of water and gravel, and is easy to quickly disassemble and assemble.

[0009] Preferably, the support frame is provided with a rotatable limit turntable at the top port of the installation port, and the side surface of the limit turntable is abutted against the roller of the inclined installation station. When the conveyor belt deviates, the limit turntable is used to touch and limit the conveyor belt from continuing to deviate.

The horizontal installation station 121 and the inclined installation station 122 are both installed with rollers 14 for receiving the transmission belt 100 through shock-absorbing seats 13. The transmission belt 100 is placed at the installation port 12 and contacts the transmission belt 100 by means of the rollers 14, so that the transmission belt 100 presents a V shape.

[0021] Among them, the shock-absorbing seat 13 has a built-in slide groove 131, and a slider 132 is embedded in the slide groove 131. The slider 132 is only allowed to move repeatedly along the direction of the slide groove 131. A shock-absorbing spring 133 is arranged between the slider 132 and the bottom of the slide groove 131. The shock-absorbing spring 133 and the slider 132 extend obliquely upward to form a connecting rod 134, and the top of the connecting rod 134 is connected to the roller 14 through a bearing 135.

[0022] This embodiment is mainly set up by installing a horizontal installation station 121 and an inclined installation station 122 at the installation port 12, so that the conveyor belt 100 placed here is presented in a V shape, thereby meeting the requirements of conveying gravel. At the same time, a shock-absorbing seat 13 is set under each roller. Relying on the slide groove 131, the slider 132 and the shock-absorbing spring 133 set up by the shock-absorbing seat 13, the shock-absorbing effect can be achieved during the transmission process by relying on the expansion and contraction buffering of the shock-absorbing spring 133, thereby avoiding the problem of gravel falling out and mud and water splashing due to excessive amplitude.

The installation by this plug-in method can not only quickly complete the disassembly and assembly of the support frame 1, but also leave no outwardly protruding components in the tunnel after disassembly and assembly, thereby not affecting the tunnel construction.

[0024] Furthermore, in order to prevent the conveyor belt 100 from deviating during operation, that is, from escaping from the roller 14 of the inclined plane installation station, the support frame 1 of this embodiment is provided with a self-rotating limit turntable 19 at the top port of the installation port 12, and the side of the limit turntable 19 is close to the roller 14 of the inclined plane installation station 122. When the conveyor belt 100 deviates, the limit turntable 19 is used to contact and limit the conveyor belt 100 from continuing to deviate. In addition, in order to achieve the best effect, the limit turntable 19 of this embodiment is an inverted cone.
