The above defects make it difficult to balance between high-efficiency slag discharge and equipment stability of the existing device, and restrict the tunneling efficiency. UTILITY MODEL CONTENTS

DETAILED DESCRIPTION

[0036] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0037] Please refer toFigures 1 to 6 The utility model provides a technical scheme: a kind of high-efficiency slagging assembly of TBM tunnel construction, comprising: support frame 1, two side plates 2, driving roller 3, even material component, driven roller 4, conveying belt 5 and carrier roller 6, two side plates 2 are respectively fixedly installed at the both ends of support frame 1;Driving roller 3 rotatably installed at the end of two side plates 2;Even material component is set at the top of support frame 1, and it is located between two side plates 2, and driving roller 3 is also provided with driving assembly;Driven roller 4 rotatably installed at the other end of two side plates 2;The inner side of conveying belt 5 is respectively connected with driving roller 3 and driven roller 4 friction;Several carrier rollers 6 are rotatably installed between two side plates 2 respectively, and overlap with conveying belt 5.

[0038] It needs to be explained that driving assembly drives driving roller 3 to rotate after starting, and driving conveying belt 5 forms closed circulation operation by friction, and tunnel slag is first evenly distributed by even material component, to avoid accumulation and blockage, and then evenly laid on the surface of conveying belt 5, conveying belt 5 is continuously operated along the direction of side plate 2 under the drive of driving roller 3, carrier roller 6 evenly supports the middle section of conveying belt 5 to keep flat conveying surface, effectively reduces operating resistance, and driven roller 4 maintains stable tension of conveying belt 5 by friction transmission, in the process of high-speed operation, even material component continuously controls slag thickness, driving roller 3 and driven roller 4 cooperate to ensure the constant linear velocity of conveying belt 5, forming uninterrupted slag conveying channel, and each component cooperates to realize continuous operation of slag from even distribution to high-speed conveying, which significantly improves slagging efficiency.

[0039] As a preferred scheme, further, dust cover 7 is installed on two side plates 2, and dust cover 7 is detachably connected with two side plates 2 by a plurality of screws.When tunnel excavation encounters high dust working condition, the operator uses the screw to quickly install the dust cover 7 to form a closed chamber, and in the process of high-speed operation of conveying belt 5 driven by the driving assembly, the dust cover 7 effectively blocks the dust diffusion generated by the slag conveying, and the detachable structure ensures that the cover can be quickly removed by removing the screws when the equipment is overhauled or the wide-width slagging is required, which not only maintains the efficient operation of the slag conveying system, but also realizes the dynamic balance of dust control and equipment accessibility. The modular dust cover 7 is easy to disassemble, which avoids the interference of traditional fixed dustproof device on continuous slagging operation.

[0040] As a preferred scheme, further, the driving assembly comprises: driving motor 8, driving gear 9, driven gear 10, chain wheel 11 and chain 12, driving motor 8 is installed at the bottom end of support frame 1;Driving gear 9 is fixedly connected on the driving end of driving motor 8;Driven gear 10 is sleeved on the rotating shaft of driving roller 3, and engages with driving gear 9;Two chain wheels 11 are fixedly arranged on the rotating shafts of driving roller 3 and driven roller 4 respectively;Chain 12 is sleeved on two chain wheels 11.

[0041] It should be noted that after the driving motor 8 is started, the driving end drives the driving gear 9 to rotate at high speed, and through the gear engagement, the power is transmitted to the driven gear 10, so that the driving roller 3 generates an initial torque; at the same time, the sprocket 11 fixed to the shaft end of the driving roller 3 rotates synchronously with the shaft, and through the precisely matched chain 12, the power is transmitted to the sprocket 11 at the shaft end of the driven roller 4, forming a transmission system. In the continuous operation process, the driving assembly adopts modularization to allow the chain 12 or gear set to be individually disassembled without affecting other parts, thereby significantly shortening the downtime.

[0042] As a preferred solution, further, the dust cover 7 is provided with a feeding port on one side, and a guide plate 14 is fixedly arranged at the feeding port. When the slag is introduced through the feeding port, the guide plate 14 fixed to the edge of the feeding port guides the slag to accurately fall into the central area of the conveying belt 5 through the inclined angle thereof.

[0043] As a preferred solution, further, the material uniformizing assembly comprises a fixing member 15, grooves 16 and protrusions 17. The fixing member 15 is fixedly arranged between the two side plates 2; a plurality of grooves 16 are staggered arranged on the surface of the fixing member 15; and a plurality of protrusions 17 are fixedly arranged on the inner side of the conveying belt 5 and alternately matched with the grooves 16.

[0044] It should be noted that when the slag enters the working area, the staggered grooves 16 on the surface of the fixing member 15 periodically engage with the regularly distributed protrusions 17 on the inner side of the conveying belt 5, and each engagement generates high-frequency mechanical vibration in the vertical direction, forcing the slag layer to produce longitudinal layering effect. Under the action of the vibration screening, the large-diameter materials gather in the middle of the conveying belt 5, and the transverse shear force promotes the fine particles to uniformly spread to both sides; during the dynamic material uniformizing process, the thickness of the slag layer is automatically adjusted to the balanced state, so that the transverse tension distribution of the conveying belt 5 tends to be consistent, effectively offsetting the eccentric moment caused by the unilateral material accumulation; at the same time, the precise matching of the grooves 13 and the protrusions 17 continuously maintains the running track of the conveying belt 5, eliminating the risk of edge relaxation; the directional shunting effect of the guide plate 14 in the dust cover 7 cooperates with the vibration material uniformizing to suppress dust escape while ensuring smooth feeding. Through the multiple mechanisms of mechanical vibration self-regulation and geometric matching dynamic compensation, the entire system realizes the closed-loop control of uniform distribution of the slag and stable operation of the conveying belt 5.

[0045] As a preferred solution, further, the plurality of carrier rollers 6, the driving roller 3 and the driven roller 4 are each provided with a slot 13 for the protrusions 17 to pass through. When the conveyor belt 5 is running with the periodically distributed protrusions 17, the slots 13 provided on the surface of the carrier rollers 6, the driving roller 3 and the driven roller 4 form a dynamic cooperation with the protrusions 17, each slot 13 is uniformly arranged along the roller surface, in the process of the roller body rotating, the protrusions 17 smoothly pass through the surface of the roller body under the guidance of the slots 13, through the precise matching of the slots 13 and the protrusions 17, both the continuous support of the roller body to the conveyor belt 5 and the elimination of the motion interference are achieved, thereby guaranteeing the efficient and stable operation of the conveying system.
