Description

Technical Field

[0001] The utility model relates to the technical field of tunneling machines, in particular to a shovel mechanism with anti-blocking function and a tunneling machine. Background Art

[0002] A roadheader is a piece of equipment used for mining and excavation. It can be used for mining and tunnel construction underground. Roadheaders can be divided into many types according to their application areas and characteristics, such as shield machines, rock tunneling machines, horizontal tunneling machines, etc. These different types of roadheaders have different working principles and application scopes.

[0003] Working mode: It is mainly composed of traveling mechanism, working mechanism, loading mechanism and transfer mechanism. As the traveling mechanism moves forward, the cutting head in the working mechanism continuously breaks the rock and transports the broken rock away. It has the advantages of safety, high efficiency and good tunnel quality, but it is expensive, complex in structure and has high loss.

[0004] When a conventional tunnel boring machine is crushing the rock through the cutting head, it will be subjected to the reaction force generated by the rock after being stressed. This reaction force will drive the entire tunnel boring machine to deviate to one side of the tunnel. As the operation time increases, the side of the tunnel boring machine will be close to the side of the tunnel, thereby affecting the cutting operation.

[0005] Therefore, in view of this, the existing structure and defects are studied and improved, and a shovel mechanism and a tunnel boring machine with anti-blocking function are proposed. Utility Model Content

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a shovel plate mechanism and a tunnel boring machine with anti-blocking function, comprising an upper shovel plate and an anti-blocking component, a star wheel mechanism is installed on the top of the upper shovel plate, and an obstacle removal component is installed on one side of the star wheel mechanism, the bottom of the upper shovel plate is connected to the lower shovel plate, and a reinforcing plate is installed in the center of the bottom of the lower shovel plate, and protective chassis are arranged on the left and right sides of the reinforcing plate, the anti-blocking component is installed inside the protective chassis, the anti-blocking component comprises a stabilizing plate, a guide guard plate, a side push plate and a hydraulic push rod, one side of the stabilizing plate is connected to the guide guard plate, and the side of the guide guard plate away from the stabilizing plate is connected to the side push plate, and a hydraulic push rod is installed on the bottom of the guide guard plate.

[0008] Furthermore, the star wheel mechanism is symmetrically installed on the left and right sides of the top surface of the upper shovel plate, and the lower shovel plate is welded to the upper shovel plate.

[0009] Furthermore, the obstacle removal assembly includes a stabilizing pile, an electric swing shaft, a rotating motor and an obstacle removal plate. The electric swing shaft is installed on the top of the stabilizing pile, and the rotating motor is installed laterally on the top of the electric swing shaft, and the obstacle removal plate is installed on the power output end of the rotating motor through a coupling.

[0010] Furthermore, the electric swing shaft is used to drive the rotating motor to swing left and right in the horizontal direction, and the rotating motor is used to drive the obstacle removal plate to rotate axially in the horizontal direction.

[0011] Furthermore, the protective chassis is fixedly mounted on the bottom surface of the lower shovel plate, and the stabilizing plate, the guide guard plate and the hydraulic push rod are all installed between the lower shovel plate and the protective chassis.

[0012] Furthermore, one end of the hydraulic push rod is connected to the bottom of the stabilizing plate, and one end of the hydraulic push rod away from the stabilizing plate is fixedly connected to the side of the side push plate.

[0013] Furthermore, the guide guard plate is slidably connected to the stabilizing plate, and the side thrust plate is vertically connected to a side of the guide guard plate away from the stabilizing plate, and the guide guard plate and the side thrust plate are welded.

[0015] The utility model provides a shovel mechanism and a tunneling machine with anti-blocking function, which have the following features:

[0016] Beneficial effects:

[0017] 1. The utility model has an anti-blocking component symmetrically connected and installed at the bottom of the lower shovel plate. When the entire tunnel boring machine is crushing the rock, as the hydraulic push rod is stretched and retracted in the horizontal direction, the side push plate connected to one end of the hydraulic push rod is pushed in the horizontal direction toward the side away from the lower shovel plate. By using the above structure, on the one hand, the rock fragments blocking the side of the entire shovel plate mechanism can be cleared to facilitate the smooth movement of the tunnel boring machine and reduce the damage of the crushed stones to the tunnel boring machine. On the other hand, the side push plate can be pushed to abut against the inner wall surface of the travel channel to ensure the stability of the head structure of the entire device when the tunnel boring machine is crushing the rock in front, and prevent the reaction force generated by the heat of the rock from causing severe shaking and deviation of the head part of the tunnel boring machine, thereby minimizing the impact on the efficiency of the rock crushing operation.

[0018] 2. The utility model installs an obstacle removal component on one side of the star wheel mechanism. When the star wheel mechanism symmetrically installed on the top surface of the upper shovel plate is in operation, the obstacle removal component arranged on one side of the star wheel mechanism will also operate synchronously, and the electric swing shaft structure is used to operate, so that the rotating motor installed with the obstacle removal plate can swing left and right at a certain angle in the horizontal direction, and the rotating motor can drive the obstacle removal plate to rotate axially in the horizontal direction. The operation of the above structure can be used to remove the gravel accumulated on the top of the star wheel mechanism, which can assist the star wheel mechanism in stirring and transporting the gravel, and can also assist the star wheel mechanism in structural cleaning to prevent excessive gravel from causing structural blockage of the star wheel mechanism and affecting normal operation.

The anti-blocking component 7 is installed by symmetrically connecting it to the bottom of the lower shovel plate 4. When the entire tunneling machine is crushing the rock, as the hydraulic push rod 704 expands and contracts in the horizontal direction, the side push plate 703 connected to one end of it is pushed in the horizontal direction toward the side away from the lower shovel plate 4, so that the rock fragments blocking the side of the entire shovel plate mechanism can be cleared.

[0026] like Figures 1 to 4 As shown, the star wheel mechanism 2 is symmetrically installed on the left and right sides of the top surface of the upper shovel plate 1, and the lower shovel plate 4 is welded to the upper shovel plate 1. The obstacle removal component 3 includes a stabilizing pile 301, an electric swing shaft 302, a rotating motor 303 and an obstacle removal plate 304. The electric swing shaft 302 is installed on the top of the stabilizing pile 301, and the rotating motor 303 is installed horizontally on the top of the electric swing shaft 302, and the power output end of the rotating motor 303 is installed with the obstacle removal plate 304 through a coupling.
