Description

Technical Field

[0001] The utility model relates to the field of rescue devices in mines or tunnels, in particular to an emergency escape device for a tunnel boring machine. Background Art

[0002] TBMs usually dig underground. For safety reasons, emergency escape passages are usually set up in the tunnel for people to escape in an emergency. As the TBMs dig forward, the tunnels formed often have an exit every few kilometers. If such a long distance is only escaped by manual labor, the evacuation speed will be slow and the narrow evacuation space will easily cause crowding and trampling. Therefore, when an emergency occurs and people need to escape, they usually take transportation to escape.

[0003] like Figure 1 As shown, the roadheader will use a rubber-wheeled vehicle 3 under normal use. The trailer 2 has a passage for the rubber-wheeled vehicle to pass through, and the rubber-wheeled vehicle 3 needs to reciprocate through the passage. In the prior art, there is a method of using a rubber-wheeled vehicle to transport personnel from the tunnel to the outside. However, the space of the rubber-wheeled vehicle is small, and the number of personnel that can be carried is limited. In addition, the rubber-wheeled vehicle is not a dedicated rescue vehicle. It is usually used for slag removal. The rubber-wheeled vehicle will reciprocate in the tunnel, that is, the rubber-wheeled vehicle is not always inside the tunnel. If the rubber-wheeled vehicle happens to be outside the tunnel 1 when an accident occurs, the rescue time will be extended.

[0004] The prior art also has a technical solution of configuring a special rescue vehicle in the tunnel boring machine. For example, the Chinese utility model patent with authorization announcement number CN214616657U discloses a shield machine long-distance tunnel emergency escape system and a shield machine. The system is arranged on the trailer of the shield machine, and a towing platform (i.e., an emergency parking platform) is arranged on the side of the trailer. The towing platform avoids the middle position to avoid affecting the passage of the rubber-wheeled vehicle. In addition, a flip platform hingedly connected to the trailer platform is also arranged on the trailer platform. The flip platform is in a vertical state when the shield machine is in normal use and does not affect the passage of the rubber-wheeled vehicle. When the rescue vehicle on the towing platform is needed, the flip platform is flipped and one end is placed at the bottom of the tunnel, so that the towing platform and the flip platform form a rescue channel for the rescue vehicle to drive out.

[0005] However, in the above technical solution, the rescue vehicle is arranged at the tail of the trailer. In order to ensure the structural strength, the trailer on the shield machine is also provided with columns. The columns are arranged vertically. If the rescue vehicle parked on the trailer wants to drive to the bottom of the tunnel, it cannot interfere with the columns in the width direction. Therefore, the emergency parking platform needs to be arranged on the outside of the columns and cannot cross the columns. That is to say, the emergency parking platform is arranged on the outside of the columns and is limited by the distance between the side wall of the tunnel and the columns. Therefore, the width of general rescue vehicles is narrow to facilitate the arrangement on the tunnel boring machine, which in turn affects the number of people the rescue vehicle can carry. At the same time, the rescue vehicle needs to drive from the emergency parking platform to the bottom of the tunnel on the flip platform. The flip platform is tilted when forming a rescue channel. That is to say, in the process of the rescue vehicle driving to the bottom of the tunnel, it needs to avoid the columns and turn. At this time, the rescue channel is tilted, which requires high driving skills and is difficult to drive, and there are safety risks. Utility Model Content

[0006] The utility model aims to provide an emergency escape device for a tunnel boring machine, which is used to solve the problems in the prior art that in order to ensure the passage of a rescue vehicle, the rescue vehicle cannot cross the pillars, resulting in a narrow width of the rescue vehicle under the influence of the pillars, thereby making the rescue vehicle able to carry fewer people; and because the rescue vehicle needs to turn and avoid the pillars in the process of driving to the bottom of the tunnel, it has high requirements on driving skills and great driving difficulty.

[0007] In order to achieve the above-mentioned purpose, the emergency escape device of the tunnel boring machine in the utility model adopts the following technical scheme:

[0008] A tunnel boring machine emergency escape device comprises a trailer, a vehicle passage is provided in the middle of the trailer, an emergency parking platform is provided on at least one side of the vehicle passage, a parking platform for parking a rescue vehicle is provided on the emergency parking platform, the parking platform is connected to the top frame of the trailer through a lifting mechanism and a left and right lateral movement mechanism, so that the parking platform is moved to the vehicle passage of the trailer through the left and right lateral movement mechanism and then descended to the bottom of the tunnel through the lifting mechanism, the lifting mechanism comprises two lifting connectors connected to the front end and / or rear end of the parking platform and arranged on the left and right, the width between the two lifting connectors is sufficient for the rescue vehicle to be able to drive down from the parking platform into the tunnel directly, or the two lifting connectors are detachably connected to the parking platform, so that the rescue vehicle can be driven down from the parking platform into the tunnel after the lifting connectors are removed.

That is to say, by setting the lifting mechanism and the left and right lateral movement mechanism, the rescue vehicle does not need to be driven out from the emergency parking platform, but can be directly moved to the bottom of the tunnel by left and right movement and lifting movement. The pillars will not affect the movement of the rescue vehicle, and the lifting mechanism directly moves the parking platform to the bottom of the tunnel, so that the vehicle is directly close to the bottom of the tunnel. When moving the rescue vehicle to the tunnel, it only needs to drive forward, thereby solving the problem that in the prior art, in order to ensure the passage of the rescue vehicle, the rescue vehicle cannot cross the pillars, and under the influence of the pillars, the width of the rescue vehicle is narrow, so that the rescue vehicle can carry fewer people; and because the rescue vehicle needs to turn and avoid the pillars in the process of driving to the bottom of the tunnel, it has high requirements on driving skills and high driving difficulty.

[0010] Furthermore, the left and right transverse movement mechanism includes a traveling frame, the lifting mechanism is arranged on the traveling frame, and the top frame of the trailer is provided with transverse guide rails extending left and right.

By setting up a transverse movement power source, it is convenient to provide power for the movement of the walking frame.

[0012] Furthermore, there are two transverse guide rails, and the cross-sections of the two transverse guide rails are both "L"-shaped, including a horizontally arranged transverse horizontal guide plate and a vertically arranged transverse vertical guide plate. The walking frame is provided with transverse walking wheels that cooperate with the guidance of the transverse horizontal guide plate and transverse guide wheels that cooperate with the guidance of the transverse vertical guide plate.

[0016] Furthermore, the lifting control structure includes a lifting frame installed on a traveling frame and guided to move along the forward and backward directions, and a pulley installed on the traveling frame. The wire rope passes around the pulley and is connected to the lifting frame. The lifting control structure also includes a forward and backward moving power source for driving the lifting frame to move forward and backward.

[0017] The beneficial effect of the above technical solution is that by setting a lifting frame that can move forward and backward along the walking frame, the wire rope can be controlled, and by setting a pulley to facilitate connection with the wire rope, the parking platform can be better controlled, thereby controlling the movement of the parking platform.

[0018] Furthermore, the pulley includes two connecting wheels respectively arranged at the front end of the walking frame, two connecting wheels arranged at the rear end of the walking frame, and two reversing wheels arranged at the front end or the rear end of the walking frame. The wire rope has two front and rear groups, one group of wire ropes is directly connected to the parking platform after passing through the connecting wheel close to the reversing wheel, and the other group is connected to the parking platform after passing through the reversing wheel and the connecting wheel far away from the reversing wheel in sequence.

[0020] Furthermore, the traveling frame is provided with a longitudinal track arranged along the front-rear direction, the longitudinal track includes two longitudinal guide rails arranged in parallel, and the lifting frame is provided with a lifting roller that rolls with the longitudinal guide rail.

DETAILED DESCRIPTION

[0037] The features and performance of the present invention are further described in detail below in conjunction with the embodiments.

[0038] In the utility model, the parking platform is guided on the top frame of the trailer to facilitate the movement of the parking platform. At the same time, a lifting mechanism for controlling the lifting movement of the parking platform is also provided, so that the emergency parking platform does not need to be set according to the position of the column, and can cross the column, thereby facilitating the increase of the width of the emergency parking platform and the rescue vehicle, thereby carrying more people.

[0039] In the embodiment 1 of the emergency escape device of the tunnel boring machine in the utility model:

[0040] like Figure 2 , Figure 3 and Figure 4 As shown, in this embodiment, the emergency escape device of the tunnel boring machine includes a trailer 2 and an emergency parking platform for parking a rescue vehicle 7 arranged on the trailer 2 of the tunnel boring machine. A parking platform 6 for placing the rescue vehicle 7 is parked on the emergency parking platform. A transverse track is arranged on the top frame 21 of the trailer 2 and is arranged perpendicular to the extension direction of the tunnel 1. The transverse track is used to cross the column in the transverse direction, that is, the transverse track includes both the part between the column and the side wall of the tunnel 1 and the part inside the column. The parking platform 6 is guided and arranged on the transverse track so that the parking platform 6 can move laterally relative to the trailer 2. Accordingly, the parking platform 6 can also move across the column. The cross section of the tunnel 1 is circular, so the distance from the bottom will not be the same at different positions. When the parking platform 6 moves from the side to the middle, the emergency parking platform will have a certain height from the bottom of the tunnel 1. Therefore, a lifting mechanism needs to be set to smoothly move the parking platform 6 to the tunnel 1, thereby facilitating the movement of the rescue vehicle 7 to the bottom of the tunnel 1.

[0041] Specifically, Figure 8As shown, the top frame 21 of the trailer 2 is a horizontally arranged rectangular frame, and the rectangular frame has four sides, two of which are parallel and perpendicular to the extension direction of the tunnel 1, and the other two sides are also parallel and along the extension direction of the tunnel 1. The transverse tracks are arranged on the two sides perpendicular to the extension direction of the tunnel 1, including transverse guide rails 211 respectively arranged on the two sides, that is, the extension direction of the transverse track is perpendicular to the extension direction of the tunnel 1. The left and right transverse movement mechanism also includes a traveling frame 4 guided and matched with the two transverse guide rails 211. Of course, in other embodiments, two transverse guide rails 211 may no longer be provided, but only one transverse guide rail 211 may be provided in the middle position; or two transverse guide rails 211 may still be provided, but a separate traveling frame 4 may no longer be provided, but a vertically arranged L-shaped flange and the transverse guide rail 211 may be provided on the parking platform 6 for guiding movement.

[0042] There are many forms of guided movement, which can be sliding cooperation between the slide groove and the slider, or rolling cooperation. In this embodiment, rolling cooperation with less friction is adopted. Figure 5 , Figure 6 and Figure 8 As shown, the cross section of the transverse guide rail 211 is "L" shaped, and has two plates perpendicular to each other. The transverse guide rail 211 includes a horizontally arranged transverse horizontal guide plate 2111 and a vertically arranged transverse vertical guide plate 2112. The walking frame 4 is provided with a transverse walking wheel 43 that cooperates with the transverse horizontal guide plate 2111 and a transverse guide wheel 44 that cooperates with the transverse vertical guide plate 2112. That is to say, the rotation axis of the transverse walking wheel 43 is located in the horizontal plane, and the rotation axis of the transverse guide wheel 44 is located in the vertical plane. During the movement, the transverse walking wheel 43 cooperates with the transverse horizontal guide plate 2111 to support the rescue vehicle 7. The transverse guide wheel 44 and the transverse vertical guide plate 2112 do not directly bear a large gravity, but play a guiding role during the movement to prevent the walking frame 4 from deflecting during the movement. Of course, in other embodiments, the transverse guide rail 211 may be configured as a channel steel, and the transverse running wheels 43 and the transverse guide wheels 44 on the running frame 4 are disposed in the U-shaped grooves in the channel steel. It is worth noting that the transverse running wheels and the transverse guide wheels are not limitations on the arrangement direction and axis direction of the running wheels and the guide wheels, but are only disposed on the transverse rail.

[0043] In order to facilitate the movement of the traveling frame 4 relative to the transverse track, a lateral moving power source is also provided in the present embodiment to drive the traveling frame 4 to move. Specifically, a direct-acting motion mechanism is provided between the traveling frame 4 and the top frame 21 of the trailer 2. In the present embodiment, the direct-acting motion mechanism is a moving cylinder 42. Of course, in other embodiments, the direct-acting motion mechanism can also be set as a cylinder or an electric push rod.

[0044] like Figure 4 and Figure 5 As shown, in this embodiment, a lifting mechanism is arranged between the traveling frame 4 and the parking platform 6, and the lifting mechanism includes a lifting connection member, and in this embodiment, the lifting connection member is a steel wire rope 8, and one end of the steel wire rope 8 is connected to the parking platform 6. In order to control the lifting and lowering of the parking platform 6, the lifting mechanism also includes a lifting control structure for lifting and lowering the end of the steel wire rope 8 connected to the parking platform 6, that is, the two ends of the steel wire rope 8 are respectively connected to the parking platform 6 and the lifting control structure. Specifically, the lifting control structure includes a pulley for winding the steel wire rope 8 arranged on the traveling frame 4 and a lifting frame 5 for driving the other end of the steel wire rope 8 away from the parking platform 6 to move, and the lifting frame 5 is arranged on the traveling frame 4 along the front-back direction to guide the lifting frame 5 so that the parking platform 6 can move up and down. Since one end of the steel wire rope 8 is connected to the parking platform 6 and the other end is connected to the lifting frame 5, when the lifting frame 5 is guided and moved along the front-back direction, the steel wire rope 8 moves with the lifting frame 5, thereby enabling the parking platform 6 to move up and down. Of course, in other embodiments, the lifting frame 5 may no longer be used, and a winch may be used directly to reel in the wire rope 8 .

[0045] The parking platform 6 moves under the drive of the steel wire rope 8. For smooth operation, the parking platform 6 is connected and driven by the steel wire rope 8 on all sides. The steel wire rope 8 needs to be guided by the pulley in the process of connecting with the parking platform 6. The pulley includes two connecting wheels respectively arranged at the front end of the walking frame, two connecting wheels arranged at the rear end of the walking frame, and two reversing wheels 47 arranged at the front end or the rear end of the walking frame, specifically including a first connecting wheel 45 and a second connecting wheel 46. The steel wire rope 8 has two groups, front and rear, in which one group of steel wire ropes 8 is connected to the parking platform 6 through the second connecting wheel 46 of the two groups of connecting wheels close to the reversing wheel 47, and the other group of steel wire ropes 8 is wound around the first connecting wheel 45 after passing through the reversing wheel 47 and connected to the parking platform 6. That is to say, if the front side and the rear side of the parking platform 6 need to be lifted synchronously, the steel wire rope 8 needs to move towards each other, so a group of reversing wheels 47 is provided to facilitate direction switching, that is to say, only one lifting frame 5 is needed to lift or lower the parking platform 6 at this time. Of course, in other embodiments, the reversing wheel 47 may not be provided. In this case, two relatively movable lifting frames 5 are required to be provided to control the movement of the two lifting frames 5 toward or away from each other to drive the parking platform 6 to move synchronously.

[0046] like Figure 6 and Figure 7As shown, in order to realize the lifting and lowering of the parking platform 6 in this embodiment, the lifting frame 5 needs to move on the traveling frame 4, so the traveling frame 4 is provided with a longitudinal track arranged in the front-to-back direction, and the longitudinal track includes two groups of longitudinal guide rails 41 arranged in parallel, and the lifting frame 5 is provided with a lifting roller that rolls with the longitudinal guide rails 41. The rolling fit makes the friction force smaller during the movement, which is convenient for movement. Of course, in other embodiments, a front-to-back slide groove can also be provided on the traveling frame 4, and a slider that cooperates with the slide groove can be provided at the end of the lifting frame 5.

[0047] like Figure 6 and Figure 7 As shown, during the movement of the lifting frame 5 along the longitudinal guide rail 41, it is necessary to ensure the smooth operation of the lifting frame 5, so the cross section of the longitudinal guide rail 41 is "L" shaped, including a horizontally arranged longitudinal horizontal guide plate 411 and a vertically arranged longitudinal vertical guide plate 412, and the traveling frame 4 is provided with a lifting travel wheel 51 that cooperates with the longitudinal horizontal guide plate 411 and a lifting guide wheel 52 that cooperates with the transverse vertical guide plate 2112. In the process of moving, the lifting travel wheel 51 plays the purpose of supporting and walking, and the lifting guide wheel 52 plays the role of guiding to avoid deflection during the movement. Of course, in other embodiments, the longitudinal guide rail 41 can also be set as a channel steel, and the lifting travel wheel 51 and the lifting guide wheel 52 of the lifting frame 5 are set in the U-shaped groove of the channel steel.

[0048] In order to push the lifting frame 5 so that the lifting frame 5 moves relative to the traveling frame 4, a forward and backward moving power source is also provided to push the lifting frame 5. A direct-acting motion mechanism is also provided between the traveling frame 4 and the lifting frame 5 to promote the guided motion of the lifting frame 5 on the traveling frame 4. In this embodiment, the direct-acting motion mechanism is a lifting cylinder 53. Of course, in other embodiments, the direct-acting motion mechanism can also be set as a cylinder or an electric push rod.

[0049] By setting the left and right lateral movement mechanism and the lifting mechanism, the parking platform 6 can first be moved laterally, and the parking platform 6 can be moved to the passage of the trailer 2, and then lowered to the bottom of the tunnel 1 through the lifting mechanism. When the parking platform 6 has been parked at the bottom of the tunnel 1, the rescue vehicle 7 needs to be driven from the parking platform 6 to the tunnel 1, that is, the lifting connection piece cannot hinder the movement of the vehicle at this time. In this embodiment, the two steel wire ropes 8 at the front of the rescue vehicle 7 are detachably connected to the parking platform 6. After moving into place, there will be no load on the steel wire ropes 8, so it can be easily disassembled. Of course, in other embodiments, the lifting connection piece can also be two telescopic cylinders arranged at intervals on the left and right sides of the front end of the parking platform 6. The telescopic cylinders are arranged vertically, and the width between the two telescopic cylinders is sufficient for the rescue vehicle 7 to be driven directly from the parking platform 6 to the tunnel 1. In this embodiment, the vehicle can run along the front end or along the rear end of the parking platform. Of course, in other embodiments, a lifting connection member may be provided only at the front end of the parking platform, and a baffle may be provided at the rear end of the parking platform to prevent the vehicle from falling. In this case, the vehicle can only drive out through the front end of the parking platform, or a lifting connection member may be provided only at the rear end of the parking platform, and a baffle may be provided at the front end of the parking platform to prevent the vehicle from falling. In this case, the vehicle can only drive out through the rear end of the parking platform.

[0050] When the traveling frame 4 and the parking platform 6 are connected by a flexible connector, the parking platform 6 will inevitably shake during the movement, especially when the traveling frame 4 starts and stops, the parking platform 6 will shake greatly due to inertia, so a buffer structure needs to be provided.

[0051] In this embodiment, a buffer 22 is provided at the end of the transverse guide rail 211, so that there is a buffer 22 between the end of the transverse guide rail 211 and the traveling frame 4. When the traveling frame 4 moves to the end of the transverse guide rail 211, the traveling frame 4 will first contact the buffer 22, so that the movement speed of the traveling frame 4 at the end of the stroke is reduced and the deceleration is relatively gentle, thereby reducing the shaking of the parking platform 6. Of course, in other embodiments, the buffer 22 can also be provided at the end of the traveling frame 4, so that the traveling frame 4 can be buffered when it runs to the end of the stroke. Of course, in other embodiments, the buffer may no longer be provided, and the speed is controlled by controlling the moving speed of the traveling frame.

The patent protection scope of the present invention shall be based on the claims. All equivalent structural changes made using the description and drawings of the present invention shall be included in the protection scope of the present invention.
