Description

Technical Field

[0001] The utility model relates to the technical field of operating machinery, in particular to a sliding device used for a roller cutter type rock boring machine. Background Art

[0002] During the tunnel excavation process, complex tunnel construction needs to be completed due to geological or on-site construction requirements. Hard rock is often encountered during coal mining or tunnel construction. Traditional excavation methods mainly include drilling and blasting and mechanical excavation. Drilling and blasting excavation construction is very prone to safety accidents when the rock formation is unstable. Mechanical excavation is safer and more efficient than drilling and blasting.

[0003] For small-volume hard rock tunnels, cantilevered tunnel boring machines are generally used to excavate tunnels. However, due to the cutting hardness limitation and cutting loss, the cost of tunnel excavation is greatly increased. In addition, traditional cantilevered tunnel boring machines need to move the entire machine forward to complete the cutting, and cannot move forward without the entire machine moving forward. The operation is relatively complicated and the work efficiency is low.

[0004] For short-distance, ultra-hard rock tunnel construction, a roller cutter rock boring machine was developed, combining the rock breaking function of the rotating cutter head of the TBM equipment and the pitch and swing function of the boom of the cantilever boring machine. However, the problem that the cutter head cannot advance when the whole machine is not advancing needs to be solved, so as to greatly improve the rock breaking capacity while ensuring the flexibility of equipment operation and meeting market demand. Utility Model Content

[0005] 1. Technical issues to be resolved

[0006] In view of the above-mentioned shortcomings and deficiencies of the prior art, the utility model provides a sliding device for a roller cutter rock boring machine, which solves the technical problem that the cutter disc cannot advance when the whole machine does not advance.

[0007] (II) Technical solution

[0008] In order to achieve the above-mentioned purpose, the main technical solutions adopted by the utility model include:

[0009] A sliding device for a roller cutter type rock boring machine, connected to a cutter head support structure of the roller cutter type rock boring machine, characterized in that it comprises: a guide column fixed to a chassis of the roller cutter type rock boring machine, a sliding frame slidably connected to the guide column, and a propulsion drive device for driving the sliding frame to slide along the guide column;

[0010] A swivel support seat is fixedly provided on the top of the sliding frame, and the cutter head support structure is rotatably connected to the sliding frame through the swivel support seat;

[0011] The propulsion drive device is connected to the rear end of the sliding frame. When the propulsion drive device drives the sliding frame to slide along the guide column, the sliding frame drives the cutter disc support structure to move at the same time.

[0012] The sliding frame is a box-shaped structure, and comprises a top plate, a bottom plate and two side plates arranged opposite to each other;

[0013] A sleeve is provided at the bottom of each side plate, and the sleeve is sleeved on the guide column so that the sliding frame is slidably connected to the guide column.

[0014] A first hinged seat is provided at the front end of the base plate, and the scraper conveyor of the roller cutter rock tunneling machine is connected to the first hinged seat through the sliding frame, so that when the sliding frame slides along the guide column, it drives the scraper conveyor to move at the same time.

[0015] A second hinged seat for connecting the propulsion drive device is provided at the rear end of the base plate.

[0016] The propulsion drive device is arranged parallel to the guide column, the fixed end of the propulsion drive device is connected to the chassis of the roller cutter rock boring machine, and the driving end of the propulsion drive device is connected to the second articulated seat.

[0017] The swivel support seat is detachably fixed to the top of the top plate, and the swivel support seat is rotatably connected to the swivel mechanism of the cutter disc support structure.

[0020] (III) Beneficial effects

[0021] The beneficial effect of the utility model is that the utility model provides a sliding device for a roller cutter type rock boring machine, and the roller cutter type rock boring machine can be fed when the whole machine is not advancing through the combined arrangement of the guide column and the sliding frame.

[0022] The sliding frame has a box-shaped structure, and the scraper conveyor can pass through the middle of the sliding frame. By arranging a first hinged seat for connecting the scraper conveyor at the front end of the bottom plate, the sliding frame can drive the scraper conveyor to move at the same time when it moves, so that the scraper conveyor can move with the feed of the cutter disc, which is convenient for collecting and transporting cut materials.

While completing the feeding in the non-advancing state, the cutter disc can swing left and right to change the cutting position of the cutter disc, realize a large range of cutting, simplify the operation steps and improve work efficiency.

[0024] By arranging a propulsion driving device at the rear end of the sliding frame, the sliding frame is driven to slide along the guide column, thereby providing forward and backward power for the sliding frame. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] The guide columns 1 are arranged in pairs. In this embodiment, two guide columns 1 are used. The front and rear ends of the guide columns 1 are detachably fixed on the chassis of the roller cutter type rock boring machine 5 .

[0037] The sliding frame 2 is a box-shaped structure, and includes a top plate 21, a bottom plate 22, and two oppositely arranged side plates 23. A sleeve 24 is provided at the bottom of each side plate 23, and the guide column 1 passes through the sleeve 24, and the sleeve 24 is sleeved on the guide column 1, so that the sliding frame 2 can slide along the guide column 1.

[0038] A first hinge seat 25 is provided at the front end of the bottom plate 22, and the scraper conveyor of the roller cutter type rock boring machine 5 can pass through the sliding frame 2 and be connected to the first hinge seat 25, so that when the sliding frame 2 slides along the guide column 1, it can simultaneously drive the scraper conveyor to move, so that the scraper conveyor moves with the cutting of the cutter disc 7, which is convenient for material transportation. The scraper conveyor is hinged to the first hinge seat 25 through a pin shaft.

[0039] A second hinge seat 26 is provided at the rear end of the bottom plate 22, and the second hinge seat 26 is used to connect the propulsion drive device 4.
