Description

Technical Field

[0001] The present application belongs to the technical field of tunnel boring machines, and in particular, relates to a support assembly and a tunnel boring machine. Background Art

[0002] In the related art, when performing anchoring operations, it is usually necessary to lift the anchor net through the support top plate on the support assembly. During the beam erection operation, it is usually necessary to set a beam supporting device on the tunnel boring machine to support the top beam through the beam supporting device to perform the beam erection operation. However, temporary support and beam supporting device are two different devices, both of which require installation space. Due to the limited space on the top of the cutting part, the temporary support and the beam supporting device cannot be installed on the top of the tunnel boring machine at the same time, which creates difficulties for the anchoring and beam erection operations of the tunnel boring machine. Summary of the invention

[0003] The present invention aims to solve or improve at least one of the above-mentioned technical problems.

[0004] A first aspect of the present invention is to provide a support assembly.

[0005] A second aspect of the present invention is to provide a tunnel boring machine.

[0006] The technical solution of the first aspect of the present invention provides a support assembly, which is applied to a tunnel boring machine, including: a base; a driving assembly, one end of which is connected to the tunnel boring machine and the other end is connected to the base, for driving the base to move; a support plate, which is arranged on the base and is used to support the anchor net; a supporting beam assembly, which is arranged on the base and is used to lift and support the top beam.

[0007] The support assembly of the present invention is applied to a tunnel boring machine. The support assembly includes a base, a driving assembly, a supporting plate and a supporting beam assembly. One end of the driving assembly is connected to the tunnel boring machine and the other end is connected to the base to drive the base to move. The supporting plate is arranged on the base to support the anchor net. The supporting beam assembly is arranged on the base to lift and support the top beam. The present application integrates the supporting beam assembly on the support assembly, improves the functional integration of the tunnel boring machine, saves equipment space, improves the production efficiency of the equipment, and saves the production cost of the equipment. In addition, the supporting plate and the supporting beam assembly share a set of driving assemblies, which saves a set of driving assemblies. Compared with the temporary support and the supporting beam device being set separately, the number of components is greatly simplified, and the contradiction that the temporary support and the supporting beam device cannot be installed on the tunnel boring machine at the same time due to the overlapping installation positions of the temporary support and the supporting beam device is resolved, which provides more operating space for the anchoring operation and beam erection operation of the tunnel boring machine. Furthermore, the supporting plate is an arched structure, so that the support assembly of the present application is suitable for arched tunnels. Of course, the supporting plate can also be a straight structure, so that it is suitable for rectangular tunnels or trapezoidal tunnels.

[0008] In the above technical solution, the support beam assembly includes: at least two slot plates, which are arranged on the base, each slot plate is provided with a limiting slot, and the multiple limiting slots are used to limit the first top beam; a top beam support plate, which is arranged on the base and is used to support the second top beam.

[0009] In the technical solution, the support beam assembly includes at least two slot plates and a top beam support plate. At least two slot plates are arranged on the base. Each slot plate is provided with a limited slot. The multiple limited slots are used to limit the first top beam. The first top beam is also the top beam to be installed. The top beam support plate is arranged on the base to support the second top beam. The second top beam is also the top beam that has been installed. In this way, when the beam is erected, the first top beam can be lifted and fixed at the position to be installed through the limited slot. Then, the top beam support plate is used to support the installed top beam for the beam erection operation. It can be understood that the top beam support plate supports the installed top beam in order to make the base in a horizontal state. The support at both ends can ensure that the front and rear forces of the base are balanced when working, and ensure the stability of the first top beam. The present application uses the slot to limit the top beam, which makes the operation more convenient, and there is no need to design a complex limit device, ensuring that it can be integrated on the support assembly. At the same time, at least two slot plates are provided to ensure the stability of the top beam to be installed, and it will not fall off during the beam erection operation to avoid accidents.

[0010] In the above technical solution, the supporting plate includes a first supporting plate and a second supporting plate which are arranged opposite to each other along the length direction of the base, and the first supporting plate can be close to or away from the second supporting plate.

[0011] In this technical solution, the support plate includes a first support plate and a second support plate that are relatively arranged along the length direction of the base. It can be understood that the first support plate and the second support plate are arranged in parallel on the base at intervals. Furthermore, the first support plate can be close to or away from the second support plate. In this way, the relative distance between the first support plate and the second support plate can be adjusted according to actual conditions, and then the support area can be arbitrarily adjusted according to the size of the anchor rod spacing to complete the anchoring operation.

[0012] In the above technical solution, the first supporting plate and the second supporting plate are both arched structures or straight structures, and the first supporting plate and the second supporting plate have the same height.

[0013] In this technical solution, the first support plate and the second support plate are both arched, and the first support plate and the second support plate have the same height, so that the tunnel boring machine of the present application can perform roof support work in an arched tunnel. Of course, the first support plate and the second support plate can also be set as a straight structure as needed, so that it can be suitable for rectangular tunnels or trapezoidal tunnels.

[0014] In the above technical solution, the tunnel boring machine includes an anchor drilling rig, and the base includes a first bottom plate and a second bottom plate. The first bottom plate can slide forward and backward relative to the second bottom plate, and both sides of the first support plate are arranged on the first bottom plate; both sides of the second support plate are arranged on the second bottom plate; when the first bottom plate slides forward and backward relative to the second bottom plate, the first support plate can be close to or away from the second support plate; the first support plate, the second support plate, the first bottom plate and the second bottom plate form a working space of the anchor drilling rig.

[0015] In this technical solution, the tunnel boring machine includes an anchor drilling rig, and the base includes a first bottom plate and a second bottom plate which are spaced apart from each other. The first bottom plate can slide forward and backward relative to the second bottom plate, and both sides of the first support plate are arranged on the first bottom plate; both sides of the second support plate are arranged on the second bottom plate, so that when the first bottom plate slides forward and backward relative to the second bottom plate, the first support plate can approach or move away from the second support plate, thereby adjusting the distance between the first support plate and the second support plate; further, the first support plate, the second support plate, the first bottom plate and the second bottom plate form a working space of the anchor drilling rig, and by adjusting the position of the first support plate, the volume of the working space can be adjusted, so that the anchor drilling rig can perform anchoring operations in the working space conveniently. It is understandable that according to actual needs, it is necessary to insert the anchor rod above the base, therefore, it is necessary to set a working space on the base, so that the anchor drill can insert the anchor rod at the corresponding position in the working space. At the same time, considering that the size of the working space may affect the operation of the anchor drill, the first support plate is slid to adjust the volume of the working space, so that the stable operation of the anchor drill can be ensured. Further, in order to improve the integration, the slot plate can be set on the first support plate, so that more operating space can be provided for the anchor driver.

[0016] In the above technical solution, the support assembly also includes a telescopic cylinder, which is arranged on the second bottom plate, and the movable end is connected to the first bottom plate, and is used to drive the first bottom plate to slide back and forth relative to the second bottom plate.

[0017] In this technical solution, the support assembly also includes a telescopic cylinder, which is arranged on the second base plate and the movable end is connected to the first base plate, and is used to drive the first base plate to slide back and forth relative to the second base plate. In this way, the first base plate can be driven by the telescopic cylinder, thereby driving the first support plate to slide, thereby adjusting the support area.

[0018] In the above technical solution, the driving assembly includes: a telescopic cylinder, a first end of which is rotatably connected to the tunnel boring machine and a second end of which is connected to the base; and an arm cylinder connected to the telescopic cylinder for driving the telescopic cylinder to rotate around the first end of the telescopic cylinder.

[0019] In this technical solution, the driving assembly includes a telescopic cylinder and an arm cylinder. The first end of the telescopic cylinder is rotatably connected to the tunnel boring machine, and the second end of the telescopic cylinder is connected to the base. The arm cylinder is connected to the telescopic cylinder and is used to drive the telescopic cylinder to rotate around the first end of the telescopic cylinder. The present application adjusts the position of the first support plate and the beam assembly by adjusting the rotation angle of the telescopic cylinder, thereby ensuring the completion of anchoring operations and beam erection operations at different positions.

[0020] In the above technical solution, the base is rotatably connected to the second end of the telescopic cylinder, and the support assembly also includes a swing cylinder connected to the base for driving the base to rotate around the second end of the telescopic cylinder.

[0021] In this technical solution, the base is rotatably connected to the second end of the telescopic cylinder, and the support assembly further includes a swing cylinder connected to the base for driving the base to rotate around the second end of the telescopic cylinder. The present application adjusts the swing angle of the base through the swing cylinder, thereby adjusting the swing angle of the first support plate and the support beam assembly, thereby ensuring the completion of anchoring operations and beam erection operations in all directions.

[0022] In the above technical solution, the support beam assembly is slidably arranged on the base.

[0023] In this technical solution, the support beam assembly is slidably arranged on the base, so that the position of the support beam assembly can be adjusted at any time according to the working situation to ensure the stability of the top beam installation.

It can be understood that the top beam support plate 142 supports the installed top beam in order to make the base 11 in a horizontal state. The supports at both ends can ensure that the front and rear forces of the base 11 are balanced when working, thereby ensuring the stability of the first top beam. The present application uses a slot to limit the top beam, making the operation more convenient.

It can be understood that according to actual needs, it is necessary to insert the anchor rod above the base 11. Therefore, it is necessary to set up a working space on the base 11 so that the anchor drilling rig can insert the anchor rod at the corresponding position in the working space. At the same time, considering that the size of the working space may affect the operation of the anchor drilling rig, the first support plate 131 is slid to adjust the volume of the working space, so as to ensure the stable operation of the anchor drilling rig.
