Description

Technical Field

[0001] The utility model relates to the field of slag cleaning devices, in particular to a slag cleaning device applied to a TBM slag cleaning belt conveyor. Background Art

[0002] TBM, also known as tunnel boring machine, is an engineering equipment that integrates multiple technologies such as mechanical, electrical, hydraulic, and automatic control. It can realize factory-based and assembly-line construction of tunnels and is widely used in the construction of railway and highway mountain tunnels.

[0003] When a tunnel boring machine is operating, a large amount of rock fragments will be generated. These rock fragments fall and accumulate at the bottom of the tunnel, hindering other processes. Therefore, mechanical equipment such as cleaning devices, slag cleaning belt conveyors and slag discharge belt conveyors are usually used to clean up the soil debris at the main beam and connecting bridge of the tunnel boring machine.

[0004] However, when the slag cleaning belt conveyor in the above-mentioned prior art is transporting soil slag, there is usually residue adhered to its surface. More residue adhesion will affect the operation of the slag cleaning belt conveyor. Therefore, a TBM slag cleaning device is proposed to clean the slag adhered to the slag cleaning belt conveyor. Summary of the invention

[0005] The technical problem to be solved by the utility model is to provide a TBM slag cleaning device which can clean the slag adhered to the slag cleaning belt conveyor and prevent the belt of the slag cleaning belt conveyor from being affected in operation due to long-term adhesion of slag.

[0020] Combine the following Figure 1-4 Further explain the utility model;

[0021] See also Figure 1-3 It includes two vertical plates 1, which are respectively arranged on both sides of the top transmission roller 3 of the front end of the slag cleaning belt conveyor 2. The two vertical plates are respectively connected to the frame of the slag cleaning belt conveyor through triangular reinforcing plates 4. A crossbeam 5 is arranged between the two vertical plates. A slot with an opening facing upward is provided on the crossbeam. A cleaning knife 6 is inserted into the slot. A threaded hole is provided on the crossbeam at the slot. A hole for the bolt to pass through is provided on the cleaning knife. The cleaning knife is connected and fixed to the crossbeam through fixing bolts 7. The blade head of the cleaning knife fits the belt of the slag cleaning belt conveyor. The cleaning knife is inserted into the crossbeam through the slot setting, and then fixed and installed through fixing bolts, so that the cleaning knife is detachable, which is convenient for disassembly and replacement of the cleaning knife.

[0022] Each vertical plate is provided with a slide groove 8, and the slide grooves of the two vertical plates are provided with a connecting assembly with the same structure, and the connecting assembly includes a first slider 9 and a second slider 10 slidably arranged in the slide groove, and the two ends of the crossbeam are respectively extended into the slide grooves of the two vertical plates and are connected and fixed to the first sliders on the two connecting assemblies;

[0023] A first connecting block 11 is fixed to the outward side of the first slider, and a second connecting block 12 is fixed to the outward side of the second slider. An upper fixing seat 13 and a lower fixing seat 14 are fixed to the vertical plates at the upper and lower ends of the slideway, respectively. A threaded rod 15 is rotatably connected to the two fixing seats. Both ends of the threaded rod pass through the fixing seats, and the part of the threaded rod extending from the lower fixing seat is connected to a screwing head 16. A threaded hole is opened on the upper fixing seat at the position corresponding to the threaded rod, and a bolt 17 is threadedly connected in the threaded hole.

[0024] The threaded rod movably passes through the first connecting block, and the threaded rod threadably passes through the second connecting block, that is, the first connecting block is provided with a round hole for the threaded rod to pass through and move, and the second connecting block is provided with a threaded hole for threaded connection with the threaded rod; a spring 18 is provided on the threaded rod located between the first connecting block and the second connecting block.

[0025] The threaded rod located in the upper fixing seat is a smooth rod.

[0026] The cleaning knife is installed through the vertical plate and the crossbeam, and the spring is used to provide elastic squeezing force for the first connecting block, so as to control the cleaning knife to press against the belt of the slag cleaning belt conveyor, thereby cleaning the belt of the slag cleaning belt conveyor and preventing the belt of the slag cleaning belt conveyor from being stuck with soil slag for a long time and affecting its operation.

[0027] The threaded rod can be twisted by setting the twisting head, and the threaded rod cooperates with the thread of the second connecting block, thereby driving the second connecting block to slide along the slide groove through the second slider, thereby compressing the spring, and then controlling the tightening force between the cleaning knife and the belt of the slag cleaning belt conveyor through the first connecting block, the first slider and the mounting beam.

[0028] By manually twisting the bolt, the bare rod portion of the threaded rod in the fixing seat can be squeezed and fixed when the bolt is tightened, so that the threaded rod is restricted and the possibility of passive rotation of the threaded rod causing movement of the second connecting block is reduced.

[0029] The working principle of the utility model is:

[0030] When in use, first insert the cleaning knife into the slot on the mounting crossbeam and lock it with the fixing bolt. At this time, the second connecting block applies elastic force to the first connecting block through the spring, so that the first connecting block drives the first slider to slide along the slide groove, thereby driving the cleaning knife to rest on the belt of the slag cleaning belt conveyor through the mounting crossbeam. When the slag cleaning belt conveyor is running, the cleaning knife cleans the belt surface of the slag cleaning belt conveyor, thereby removing the soil debris on the surface of the slag cleaning belt conveyor.

[0031] Loosen the bolts of the upper fixed seat and rotate the threaded rod by twisting the head, so that the threaded rod rotates between the fixed seats. At this time, the threaded rod drives the second connecting block to slide along the slide groove through the cooperation of the second slider and the slide groove, so that the second connecting block is close to the first connecting block, and then compresses the spring, so that the thrust of the first connecting block sliding along the slide groove through the first slider is increased, thereby adjusting the tightening force between the cleaning knife and the belt of the slag cleaning belt conveyor.

[0032] See also Figure 4 At present, a slag discharge belt conveyor 19 is arranged behind the TBM slag cleaning belt conveyor 2, and a cleaning and transporting device 20 is arranged in front of the slag cleaning belt conveyor. The cleaning and transporting device, the slag cleaning belt conveyor and the slag discharge belt conveyor are all installed on a connecting bridge 21, and the connecting bridge is arranged at the rear end of the TBM main beam 22. In the whole slag cleaning process, the cleaning and transporting device transports the slag to the slag cleaning belt conveyor, the slag cleaning belt conveyor lifts the slag and transports it to the slag discharge belt conveyor, and the slag discharge belt conveyor outputs the slag.
