Detailed Description

Along with the development of national economy, the tunnel construction process is accelerated, and the shield method is widely used due to the economy and high efficiency. The shield method is a fully mechanized construction method in the construction of the undermining method, which is a mechanized construction method for pushing shield machinery in the ground, preventing surrounding rocks around a shield shell and a duct piece support from collapsing into a tunnel, excavating soil body in front of an excavating face by a cutting device, transporting out of the tunnel by an earth-discharging machine, pressurizing and jacking at the rear part by a jack, and splicing precast concrete duct pieces to form a tunnel structure.

Open TBM (Tunnel Boring Machine ) and slurry balance shield machines are two relatively common tunneling devices. The open TBM is ballasted by the belt conveyor, has higher construction efficiency, can cope with long-distance hard rock working conditions, but has difficult tunneling in geology such as rich water, sand and mud, and the like. The main machine part of the slurry balance shield machine is isolated from the stratum, so that the water and soil pressure can be well blocked, and the slurry balance shield machine can be better adapted to the stratum with rich water, high water pressure and the like by pumping slag, but the construction efficiency is lower, and the cost is higher during continuous long-distance tunneling.

Taking an open TBM as an example, the TBM is engineering equipment for full-section tunnel construction, and the belt conveyor is an important component of the TBM and plays a role in transporting dregs, so that the performance and efficiency of the TBM greatly influence the tunnel construction progress. The TBM is provided with a belt storage bin, the belt storage bin continuously releases the belt in the tunneling process, and the conveying belt in the belt storage bin is gradually released along with the extension of the belt conveyor.

Thus, the storage capacity of the storage bins becomes a critical factor limiting TBM tunneling efficiency. The weak conveyer belt that can lead to of tape storage ability leads to the change conveyer belt, causes the joint to increase, and the conveyer belt is weak, leads to the conveyer belt fracture even when serious, causes the construction to stagnate. Meanwhile, for the TBM with multiple horizontal turns, a slag tapping scheme of the lap joint of the belt conveyor is generally adopted for slag tapping, transformation exists in the lap joint process, equipment is stopped in the transformation process, so that the construction period can be prolonged to a great extent, and the construction efficiency is reduced.

Therefore, how to improve the current situation that the existing belt storage bin has weak belt storage capacity and how to shorten the equipment downtime in the lap joint reconstruction process of the belt conveyor becomes a problem to be solved urgently.

In view of the above-mentioned deficiencies of the state of the art, related studies have been made by those skilled in the art, for example, in some implementations, a tensioned belt magazine for storing and releasing conveyor belts of a belt conveyor is disclosed, comprising a belt magazine frame and at least two belt magazine assemblies arranged in a stack on the belt magazine frame, the belt magazine assemblies comprising a redirecting unit, a slip tensioning unit and a tensioning drive unit, the redirecting unit being fixedly arranged at a first end of the belt magazine frame; the sliding tensioning unit is arranged opposite to the redirecting unit and is arranged on the belt storage bin frame body in a sliding manner; the tensioning driving unit is arranged at the second end part of the belt storage bin frame body and drives the sliding tensioning unit to reciprocate on the belt storage bin frame body; and a plurality of groups of rollers are arranged on the redirecting unit and the sliding tensioning unit, and the conveying belt is coiled on the rollers of the belt storage assemblies in sequence. In this implementation, however, tunnel construction multi-level cornering conditions are not involved.

Based on the technical problem, the embodiment of the application provides a store up area storehouse subassembly and tunnel boring device, is in including storing up area storehouse and setting at least two belt conveyors on the area storehouse, store up area storehouse and store up area storehouse including head portion store up area storehouse and afterbody store up area storehouse, compare in the current mode that only includes head portion store up area storehouse in, can increase the storage length of storing area storehouse by a wide margin, reduce sticky tape joint number of times to reduce the construction or the production time because of filling the loss of area storehouse. Through being equipped with afterbody storage area storehouse, in the overlap joint transformation process of belt feeder, can last to the belt feeder to put the area, ensure that tunnelling and belt feeder overlap joint go on in step, need not shut down to shorten the equipment downtime in the overlap joint transformation of belt feeder, shorten construction period to the utmost, improve the efficiency of construction, save because of the construction cost that the shut down produced, avoided storing up the weak current situation of area storehouse storage area ability in the related art and the relatively longer problem of equipment downtime in the overlap joint transformation process of belt feeder.

Example 1

Referring to fig. 1 to 5, an embodiment of the present application provides a tape cartridge assembly 100, which is disposed in a tunneling device, and the tunneling device is mainly applied in a tunnel and excavates a tunnel stratum.

The tunneling device comprises an open TBM tunneling machine and a slurry balance shield machine. In the embodiment of the application, an open type TBM tunneling machine is mainly taken as an example for explanation.

In addition, it should be noted that, in the embodiment of the present application, the application scenario of the tape storage bin assembly 100 is in a tunnel with multiple horizontal turns. For example, referring to fig. 1 and 2, fig. 1 and 2 are schematic views of a multi-level turning tunnel, wherein the tunnel includes a plurality of horizontal segments and a plurality of turning segments, and the turning segments are connected between two adjacent horizontal segments.

In the tunneling device, only one horizontal section can be tunneling by one belt conveyor 120, and when tunneling is completed in the horizontal section and turning is performed to enter the next horizontal section, a second belt conveyor 120 needs to be arranged. Thus, at least two continuous belt conveyors 120 are required in the present embodiment.

The tape cartridge assembly 100 includes a tape cartridge 110 with at least two belt conveyors 120 disposed on the tape cartridge 110. It will be appreciated that the storage bin 110 is used to temporarily store the excess belt conveyor 120 before and after the retractable belt conveyor 120 to meet the need for continuous advancement or retraction during tunneling.

The tape storage bin 110 includes a head tape storage bin 111 and a tail tape storage bin 112 which are arranged along the length direction of the tunneling device, the head tape storage bin 111 is positioned on one side close to the tunneling end of the tunneling device, and the tail tape storage bin 112 is positioned on one side far away from the tunneling end.

It will be appreciated that the tunnelling end, also referred to as the excavation end, is the foremost end of the tunnelling device.

In this embodiment, taking the belt conveyor 120 including the first belt conveyor 121 and the second belt conveyor 122 as an example for explanation, the first belt conveyor 121 is disposed on the front side of the second belt conveyor 122 along the tunneling direction, please refer to fig. 3, when the tunneling device tunnels along the first horizontal segment, the head belt storage bin 111 is connected to one side of the first belt conveyor 121 near the tunneling end, and the tail belt storage bin 112 is connected to one side of the first belt conveyor 121 far away from the tunneling end.

In the process, the head belt storage bin 111 plays a main belt releasing role on the first belt conveyor 121, the tail belt storage bin 112 plays a matched belt releasing role on the first belt conveyor 121, and the tunneling device tunnels through the first belt conveyor 121.

In this process, the head tape storage bin 111 and the first belt conveyor 121 are connected, and the connection position may be shown with reference to the position a in fig. 3.

With continued reference to fig. 4, when the tunneling device finishes tunneling the first horizontal segment and turns into the second horizontal segment, the head tape storage bin 111 is removed from the first belt conveyor 121, the head tape storage bin 111 pauses the tape feeding of the first belt conveyor 121, and the tail tape storage bin 112 continues the tape feeding of the first belt conveyor 121, that is, during this process, the tail tape storage bin 112 plays a main role in tape feeding of the first belt conveyor 121, and the TBM can still perform tunneling by using the tail tape storage bin 112 without stopping.

In this process, the head tape storage bin 111 and thus the first belt conveyor 121 are detached, and the detaching position may be shown with reference to the position B in fig. 4.

Meanwhile, as shown in fig. 5, the second belt conveyor 122 is overlapped between the tail belt storage bin 112 and the first belt conveyor 121, the first belt conveyor 121 and the second belt conveyor 122 are fixedly connected, and the removed head belt storage bin 111 is conveyed to the end portion of the second belt conveyor 122, which is close to the first belt conveyor 121. At this time, the head tape storage bin 111 starts to play a main role in tape feeding to the second belt conveyor 122, and the tail tape storage bin 112 plays a role in matching tape feeding to the second belt conveyor 122, so that the tunneling device tunnels through the second belt conveyor 122.

After the first belt conveyor 121 and the second belt conveyor 122 are fixedly connected, that is, at this time, the first belt conveyor 121 is a fixed belt conveyor 120, and the fixed belt conveyor 120 means: the first belt conveyor 121 can only be used for transporting dregs and can not play a role in continuous belt feeding and tunneling.

Therefore, in the embodiment of the present application, the tape storage bin 110 includes the head tape storage bin 111 and the tail tape storage bin 112, compared with the existing mode that only includes the head tape storage bin 111, the storage length of the tape storage bin 110 can be greatly increased, and the number of times of adhesive tape joints between belt conveyors in the tape storage bin 110 is reduced, so that the construction or production time lost due to filling of the tape storage bin 110 is reduced.

Through being equipped with afterbody stores up area storehouse 112, in the lap joint transformation process of belt feeder 120, can last to put the area to belt feeder 120, ensure that tunnelling and belt feeder 120 lap joint go on in step, need not shut down to shorten the equipment downtime in the lap joint transformation of belt feeder 120, shorten construction period to the maximum extent, improve efficiency of construction, save because of the construction cost that shut down produced, avoided storing up the weak current situation of area storehouse 110 storage ability among the related art, and the relatively longer problem of equipment downtime in the lap joint transformation process of belt feeder 120.

In one possible implementation, the belt conveyors 120 may include a plurality of belt conveyors 120, each belt conveyor 120 corresponding to a horizontal segment of the tunneling, the plurality of belt conveyors 120 being arranged in sequence along the tunneling direction. Illustratively, in the embodiment of the present application, the belt conveyor 120 may include two, three, four or more belt conveyors, which is not further limited in this embodiment.

When the tunneling device sequentially tunnels the plurality of horizontal segments, a next belt conveyor 120 of the plurality of belt conveyors 120 is correspondingly lapped between the tail storage bin 112 and the previous belt conveyor 120 and fixedly connected with the previous belt conveyor 120.

After the head belt storage bin 111 is removed from the previous belt conveyor 120, the tail belt storage bin 112 continues to unwind the previous belt conveyor 120, the head belt storage bin 111 is correspondingly carried to the end part of the next belt conveyor 120, which is close to one side of the previous belt conveyor 120, the head belt storage bin 111 unwinds the next belt conveyor 120, the tail belt storage bin 112 is matched with the next belt conveyor 120 to unwind, and the tunneling device is tunneled through the next belt conveyor 120.

The bottom of the belt conveyor 120 is provided with a plurality of rollers 150, and the belt conveyor 120 moves by the rollers 150.

In one possible implementation, an interlock may be provided between any two adjacent belt conveyors 120. The interlock may include control by providing interlock logic, or by providing a mechanical lock, among other things. Thus, when the tunneling device pauses tunneling, the adjacent two belt conveyors 120 are interlocked by the interlocking member, thereby avoiding the risk of safety accidents caused by misoperation.

In one possible implementation, referring to fig. 5, a muck transporting member 130 may be further included, where the muck transporting member 130 is disposed between two adjacent belt conveyors 120.

The muck transporting member 130 comprises a material receiving end 131 and a material discharging end 132 which are connected, wherein the material receiving end 131 is arranged at the end part of the front belt conveyor 120, which is close to one side of the rear belt conveyor 120, and the material discharging end 132 is arranged at the end part of the rear belt conveyor 120, which is close to one side of the front belt conveyor 120, and the material discharging end 132 and the material receiving end 131 are used for sequentially transporting muck on the belt conveyors 120 to the outside.

Taking the belt conveyor 120 including the first belt conveyor 121 and the second belt conveyor 122 as an example, when the head belt storage bin 111 on the first belt conveyor 121 is removed and correspondingly transported to the head position of the second belt conveyor 122, the lap joint is reformed, the end of the first belt conveyor 121 near the second belt conveyor 122 is increased by the material receiving end 131, the end of the second belt conveyor 122 near the first belt conveyor 121 is increased by the material discharging end 132, and meanwhile, the first belt conveyor 121 is changed into the fixed belt conveyor 120.

By including the muck transporting member 130, muck generated in the tunneling process can be transported to the outside in time, wherein the outside may be the outside of the tunnel or the outside of the tunneling apparatus.

In one possible implementation, referring to fig. 3 to 5, the apparatus may further include an end discharge member 140, the end discharge member 140 being disposed at a side of the first belt conveyor 121 remote from the muck transporting member 130, the end discharge member being configured to receive muck transported via the muck transporting member 130.

The structure, shape, number, arrangement position, etc. of the muck transporting member 130 and the end discharging member 140 are not further limited, and for example, the muck transporting member 130 may be a transporting carriage and the end discharging member 140 may be a discharging bin.

It may be added that the outermost end of the first belt conveyor 121 may be further provided with a cleaning device, such as a water kettle, a spray kettle, a water pipe, etc., so as to clean the belt conveyor 120 in time.

In one possible implementation, a driving member may be further included, where the driving member is disposed on the belt magazine 110, and the driving member is electrically connected to the belt conveyor 120 and is configured to drive the belt conveyor 120 to move.

For example, the driving member may be provided only on the head tape magazine 111, or the driving member may be provided only on the tail tape magazine 112, or the driving member may be provided on both the head tape magazine 111 and the tail tape magazine 112.
