Description

TECHNICAL FIELD

[0001] The utility model relates to a tunnel construction technical field, specifically, a tunnel trolley and tunnel trolley group. BACKGROUND

[0002] In shield machine construction, the trolley is the key equipment matched with the shield main machine. Usually, a plurality of modular trolleys (such as main trolley, segment transport trolley, grouting trolley, etc.) are combined to form a trolley group, which cooperates with the shield main machine to undertake power supply, material transportation, auxiliary construction and other functions. Therefore, the trolley is an important guarantee for the efficient and continuous tunneling of the shield machine.

[0003] The main functions of the trolley include: power and energy supply, segment transportation and assembly, muck handling and transportation, grouting and material storage, and control system and monitoring. Specifically, the main trolley is usually equipped with a hydraulic pump station, an electrical system, an air compressor, etc., to provide hydraulic power, electricity and compressed air for the shield main machine, to drive the core functions such as cutterhead rotation, propulsion system, shield tail sealing; the segment transport trolley is responsible for transporting precast segments from the tunnel entrance to the rear of the main machine, and completing segment assembly through a segment assembly machine (usually located at the rear of the main trolley or the main machine) to form a tunnel lining; the muck transport trolley transports the muck cut by the cutterhead from the soil bin through a screw conveyor or a slurry pipeline, and then transfers it to the outside of the tunnel through a belt conveyor or a muck car to maintain the continuity of tunneling and the balance of earth pressure. The grouting trolley stores grout material (such as cement, bentonite) and injects the grout into the gap between the shield tail and the segment through a pumping system to fill the interlayer and prevent settlement. The control trolley integrates an operating room, a computer and a sensor system to monitor tunneling parameters (such as thrust, torque, earth pressure), attitude adjustment and fault diagnosis in real time.

[0004] The trolley in the prior art generally adopts a door frame structure, which is located on the bearing table of the trolley. The equipment needed during tunneling can be installed inside and / or outside the door frame structure, and some pipelines can also be arranged and fixed on the outer frame of the door frame structure. The material transport vehicle walks outside the door frame trolley.

[0005] The problem of the above prior art is that the door frame trolley is not reasonably used in space.

Specific implementation

[0032] The technical scheme in the embodiments of the utility model will be apparently and completely described in combination with the drawings in the embodiments of the utility model, and 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 the person skilled in the art without creative labor belong to the protection scope of the utility model.

[0033] The utility model provides a kind of tunnel trolley, which is used in cooperation with, for example, a tunneling device of a shield machine. The tunneling device can be used for excavation of underground works such as tunnels and roadways, and has a wide range of applications in traffic tunnels, water conservancy projects, mining and municipal engineering. The main machine of the tunneling device is provided with a cutterhead, which moves by driving to realize excavation of the soil mass. In this process, hydraulic power, waterway and electricity need to be supplied to the tunneling device, and the required materials need to be continuously transported to the direction of the main machine, and the excavated materials also need to be transported out.

[0034] The tunnel trolley follows the main machine, and the number can be one or more. As shown in Figure 1 and Figure 2 , the tunnel trolley 100' in the prior art generally adopts a door frame structure, and the device 200' is fixed and carried on the door frame structure. The tunnel trolley 100' follows the main machine to walk in the tunnel 500'. The mud inlet pipe 401', the mud outlet pipe 402', the ventilation pipe 403', the cooling water inlet pipe 406', the cooling water outlet pipe 407', the industrial water pipe 408', the industrial gas pipe 409' and other pipeline structures are arranged outside the door frame structure and are fixed on the inner wall of the tunnel 500' or on the tunnel trolley 100'.

[0035] In order to realize the carrying of the device required for the operation of the tunneling machine and ensure the timely supply of materials, sufficient space is needed in the tunnel for the material transport vehicle and the trolley to walk.

[0036] For large shield devices, the internal space is large, and the door frame trolley can be used. However, for some specific tunneling scenarios, medium and small shield machines with a diameter of about 1 to 4 meters are needed to realize flexible turning and tunneling under special working conditions. However, small shield machines are limited in size, and the tunnel in the small shield construction scene is narrow, and the internal space is also very limited, so the door frame trolley in the prior art cannot be applied to small shield machines, especially it is difficult to realize the synchronous walking of the material transport vehicle and the trolley in the tunnel.

[0037] Therefore, if the above prior art is used, in the case of limited internal space in the tunnel and small size of the trolley, in order to improve the problem that the utilization degree of space of the door frame trolley is not reasonable and intensive, the utility model provides a kind of tunnel trolley, which changes the structure of the tunnel trolley, especially the setting position of the material transport vehicle, the walking track, and the shape of the trolley outer frame, adjusts the space utilization mode of the tunnel trolley, which can walk synchronously with the material transport vehicle in a small space, and carry enough devices and materials, especially suitable for cooperation with medium and small shield machines.

[0038] As shown in Figure 3 and Figure 4As shown, the tunnel trolley of the utility model comprises: a first bearing platform 110, the first bearing platform 110 is paved with a transport trolley track 113 for the walking of a transport trolley 300; a trolley wheel 140, the trolley wheel 140 is used to support the first bearing platform 110 to drive the first bearing platform 110 to move.

[0039] It can be understood that the trolley wheel 140 is arranged below the first bearing platform 110, and the trolley wheel 140 walks along the track, so that the tunnel trolley travels in the tunnel 500. The first bearing platform 110 is also used for the walking of the transport trolley 300 in the tunnel 500.

[0040] The transport trolley 300 is also called a material transport trolley or a material trolley, and the material to be transported to the main machine direction can be contained on the transport trolley 300. The transport trolley 300 travels along the transport trolley track 113 on a plurality of mutually connected and matched tunnel trolleys, so as to realize material transportation.

[0041] Unlike the prior art, the utility model lays the track 113 on the first bearing platform 110 of the tunnel trolley, so that the transport trolley 300 can walk on the tunnel trolley. Therefore, the tunnel trolley and the transport trolley 300 can realize compatible and independent movement in a smaller tunnel space, so as to ensure that the required equipment can be carried, and the transport trolley 300 can pass through the tunnel smoothly. Therefore, the tunnel trolley of the utility model is more intensive and reasonable in space utilization, and it is especially suitable for small and medium-sized shield equipment.

[0042] As shown in Figure 3 and Figure 4 , at least part of the transport trolley track 113 is laid on the left side or the right side of the first bearing platform 110 deviating from the center line. By adjusting the laying path of the transport trolley track 113 on the first bearing platform 110, the walking track of the transport trolley 300 on the first bearing platform 110 can be adjusted, and the transport trolley 300 is controlled to walk along the edge of the first bearing platform 110 as much as possible, so as to leave more space on the first bearing platform 110 for carrying other equipment required by the tunneling machine.

[0043] Preferably, as shown in Figure 4 , the first bearing platform 110 comprises a first area 111 and a second area 112 arranged side by side in the transverse direction, the first area 111 is used to bear the equipment 200 for tunneling, and the second area 112 is paved with the transport trolley track 113.

[0044] As shown in Figure 4As shown, the first support platform 110 can be used to support materials such as pipe segments and grouting materials, and to support equipment such as hydraulic units, power units, control units, water and air circuits, etc. This invention divides the first support platform 110 into two areas. The first area 111 and the second area 112 can be physically separated by structures such as partitions, grilles, or boxes, or the division can be achieved through area configuration.

[0045] like Figure 4 As shown, one improvement of the present invention over the prior art is that the portal frame structure is eliminated, and the equipment, materials, and the transport vehicle track 113 for the transport vehicle 300 are all placed on the first support platform 110. The equipment 200 is placed in the first area 111, and the transport vehicle track 113 is laid in the second area 112. The first area 111 and the second area 112 are arranged side by side, distinguished by left and right sides. Either the first area 111 or the second area 112 is on the left, and the other is on the right. The transport vehicle track 113 is laid on the left or right side of the first support platform 110, off-center. Therefore, the transport vehicle 300 of the present invention travels on the left or right side of the tunnel trolley, thus reserving more space for equipment loading and enabling the loading of all required equipment and materials within a smaller space.

[0046] like Figure 4 As shown, in some embodiments of this utility model, the tunnel trolley further includes a support member 120, which is disposed in the middle region of the first bearing platform 110 and separates the first region 111 and the second region 112 from each other.

[0047] The support member 120 can be a plate, a column, or a grating. The support member 120 can be welded to the first support platform 110, or it can be connected by bolts or other structural means, or it can be manufactured as an integral part of the first support platform 110.

[0048] One function of the support member 120 is to physically separate the first area 111 and the second area 112, facilitating the independent use of the two spaces. The support member 120 can divide the first support platform 110 into two areas of approximately equal size along the center line of the first support platform 110, or it can deviate from the center line of the first support platform 110 to divide the first support platform 110 into two areas of different sizes, or it can only divide a portion of the area above the first support platform 110, so that in addition to the first area 111 and the second area 112, there are other open areas above the first support platform 110.

[0049] The number of the support 120 can be one or more. When the number of the support 120 is one, the support 120 divides the first bearing platform 110 into a first area 111 and a second area 112. When the number of the support 120 is more than one, the number of the first area 111 and the second area 112 divided by the support 120 is two. For example, the utility model can be provided with two parallel plate supports 120 on the first bearing platform 110, and the two supports 120 enclose a middle area as the second area 112 for the transport vehicle 300 to walk on, and the area outside each of the two supports 120 is the first area 111 for carrying the containing device 200.

[0050] As shown in the drawings, in some embodiments of the utility model, the tunnel trolley further comprises: a second bearing platform 130, the second bearing platform 130 is arranged on the support 120 so that the support 120 supports the second bearing platform 130; wherein the second bearing platform 130 is used for bearing the first pipeline. Figure 4 It can be understood that the second bearing platform 130 is preferably a flat plate structure. By arranging the second bearing platform 130, the tunnel trolley has more carrying space. Another improvement of the utility model over the prior art is that the left-right symmetrical door frame support is changed to support the second bearing platform 130 by a support 120 arranged in the middle area of the bearing platform 110, thereby saving the space of the first bearing platform 110.

[0051] The number of the first pipeline can be one or more. When the number is more than one, the first pipelines can be laid side by side or stacked on the second bearing platform 130.

[0052] Preferably, the first pipeline comprises at least one of the following or a combination thereof: a mud inlet pipe 401, a mud outlet pipe 402 and a ventilation pipe 403. In other words, the upper surface of the second bearing platform 130 is suitable for carrying and fixing some pipelines with large volume or high weight, so as to ensure that they are stably supported and fixed, and save the space on the left and right sides of the tunnel trolley.

[0053] As shown in the drawings, in some embodiments of the utility model, there is a first gap space A1 for accommodating the second pipeline between the second bearing platform 130 and the first area 111, and / or between the second bearing platform 130 and the second area 112. The size of the first gap space A1 can be selected and adjusted by those skilled in the art according to actual needs. The purpose of leaving the first gap space A1 is to facilitate the arrangement of some pipelines on the lower surface of the second bearing platform 130.

[0054] Figure 4

[0055] ​​Preferably, the second pipeline includes at least one or a combination of the following: a hydraulic pipe 404, or a grease filling pipe 405 for filling the tail shield with grease. In other words, the lower surface of the second support platform 130 is suitable for mounting and fixing some pipelines from the power unit or other equipment end, and laying them under the second support platform 130 facilitates wiring and pipeline installation.

[0056] like Figure 4 As shown, in some embodiments of this utility model, a second gap space A2 is left between the first region 111 and / or the second region 112 and the tunnel 500 for laying a third pipeline. The third pipeline is a pipeline fixed to the inner wall of the tunnel 500. It can be understood that the third pipeline is a pipeline that occupies less space or is relatively lightweight. It needs to be fixed inside the tunnel 500. Therefore, it is necessary to reserve a corresponding space between the first region 111 and / or the second region 112 and the tunnel 500 for the pipeline to pass through.

[0057] For example, Figure 4 As shown, the third pipeline may include one or a combination of the following: cooling water inlet pipe 40, cooling water outlet pipe 407, industrial water pipe 408, and industrial air pipe 409.

[0058] Preferably, such as Figure 4 As shown, in some embodiments of this utility model, the first support platform 110, the support member 120, and the second support platform 130 together form an I-shaped structure. The first lateral width W1 of the first support platform 110 is greater than the second lateral width W2 of the second support platform 130.

[0059] by Figure 4 Taking the schematic diagram of the tunnel section as an example, the direction along which the tunnel is excavated or the main machine travels is called the front-to-back direction. The widths of the first bearing platform 110 and the second bearing platform 130 refer to their respective widths in the tunnel section. Figure 4 The width along the left-right direction. It should be noted that when both the first support platform 110 and the second support platform 130 are regular flat plates, their width remains constant. Figure 4 Taking the first bearing platform 110 as an example, if the left and right sides of the first bearing platform 110 and the second bearing platform 130 have chamfers, resulting in an irregular flat plate shape such as a trapezoid or an inverted trapezoid, the width referred to in this utility model is its maximum width.

[0060] One purpose of setting the first lateral width W1 to be greater than the second lateral width W2 is to ensure that the tunnel trolley is wider at the bottom and narrower at the top, thus ensuring its smooth operation. The second purpose is that the I-shaped tunnel trolley is more suitable for matching the cross-section of circular or near-circular tunnels, so as to avoid collisions with the inner wall of the tunnel 500 while carrying as much equipment as possible or having a larger carrying space.

[0061] As Figure 4 shown, in some embodiments of the present application, the bottom plate width W b of the first bearing table 110 is less than the top plate width W t of the first bearing table 110. In other words, the cross section of the first bearing table 110 forms an inverted trapezoidal shape, which is further adapted to the circular or circular-like tunnel cross section, the lower end of which can avoid the tunnel inner wall, and the upper end of which has more space for the mounting of the equipment 200, or for the smooth running of the transport vehicle 300.

[0062] In one embodiment of the present application, the first bearing table 110 has a head end a and a tail end b, and the transport vehicle track 113 can extend and bend from the middle position of the head end a to the edge position of the tail end b. In another embodiment of the present application, the first bearing table 110 has a head end a and a tail end b, and the transport vehicle track 113 extends and bends from one side edge position of the head end a to the other side edge position of the tail end b. In another embodiment of the present application, the first bearing table 110 has a head end a and a tail end b, and the transport vehicle track 113 can extend linearly from the edge position of the head end a to the edge position of the tail end b.

[0063] It can be understood that Figure 3 the tunnel trolleys in Figure 4 can cooperate with each other, Figure 3 the tunnel trolley in Figure 4 is closer to the main machine of the tunneling machine, Figure 3 the tunnel trolley in Figure 3 follows the tunnel trolley in Figure 4 , and the number thereof can be one or more. Figure 5

[0064] Figure 3 Figure 4 The common point of the tunnel trolleys in is that the first bearing table 110 is provided with a transport vehicle track 113, and at least part of the transport vehicle track 113 is close to the edge (left edge or right edge) of the first bearing table 110.

[0065] Figure 3 Figure 4 The structural differences of the tunnel trolleys in Figure 5 , and the operation mode of the tunnel trolley group as shown in will be described in detail below.

[0066] Figure 5 ​​As shown, each tunnel trolley in the tunnel trolley assembly has a head end a and a tail end b on its first support platform 110. Each tunnel trolley's first support platform 110 is equipped with a track 113. The end of the track 113 on the front tunnel trolley is connected to the front end of the track 113 on the rear tunnel trolley.

[0067] Specifically, such as Figure 5 As shown, the tunnel trolley assembly provided by this utility model includes at least: a first tunnel trolley 600 (i.e., Figure 3 The first tunnel trolley 600 has a transport track 113 that extends and bends from the middle of the head end a to the edge of the tail end b; the second tunnel trolley 700 (i.e., Figure 4 The tunnel trolley 600 is located after the tunnel trolley 600. The transport track 113 of the second tunnel trolley 700 extends in a straight line from the edge of the head end a to the edge of the tail end b. The end of the transport track 113 of the first tunnel trolley 600 and the front end of the transport track 113 of the second tunnel trolley 700 are connected to each other.

[0068] The direction along which the tunnel is excavated or the main machine travels is called the forward and backward direction, with the head end a located in front and the tail end b located behind. One or more second tunnel trolleys 700 are connected to or follow the first tunnel trolley 600 to carry materials and equipment and to facilitate the movement of the transport vehicle 300.

[0069] The second tunnel trolley 700, which is adjacent to the first tunnel trolley 600, has a straight transport track 113 that can connect with the arc-shaped or zigzag transport track 113 laid on the first tunnel trolley 600.

[0070] In other words, except for the first tunnel trolley (i.e., the first tunnel trolley 600), whose transport track 113 is extended and curved, the transport tracks 113 of the subsequent second to N tunnel trolleys are all straight and located near the edge (either to the left or right). The transport vehicle 300 travels along the edge of one or more second tunnel trolleys 700, passing through the transport tracks 113 on each second tunnel trolley 700 one by one from back to front, until it reaches the first tunnel trolley 600. There, it boards the curved or zigzag transport track 113 and travels from the edge to the center line, facilitating the delivery of materials to the host machine.

[0071] It is understandable that if the first tunnel trolley 600 does not need to carry other equipment, its support platform can be laid with only the track 113, without any other structures or components.

[0072] When the transport track 113 of the second tunnel trolley 700 is laid on the left, the transport track 113 of the first tunnel trolley 600 turns to the left when it approaches the tail end b. Correspondingly, when the transport track 113 of the second tunnel trolley 700 is laid on the right, the transport track 113 of the first tunnel trolley 600 also turns to the right when it approaches the tail end b.

[0073] Adopting such Figure 5 The purpose of the track connection method shown is to facilitate material transportation. In particular, when using a transport vehicle 300 to transport tunnel segments, although the transport vehicle 300 carrying the segments can travel along the edge above the second tunnel trolley 700, once it reaches the first tunnel trolley 600, it is preferable that the transport vehicle 300 travel to the middle area or centerline of the first tunnel trolley 600 so that the segment-carrying machine can grab and assemble the segments. For this purpose, the transport vehicle track 113 of the first tunnel trolley (i.e., the first tunnel trolley 600) needs to be extended and bent to change the travel trajectory of the transport vehicle 300. It can be understood that there are various ways to extend the travel trajectory of the transport vehicle 300 from the edge to the center area. Figure 6 Some of the implementation methods are given. Figure 6 In section A, the transport vehicle 300 travels along a straight line near the edge on the second tunnel trolley 700, and then turns along an arc on the first tunnel trolley 600 to the center line position. Figure 6 In section B, the transport vehicle 300 first travels along a straight line near the edge on the second tunnel trolley 700, then turns along a zigzag line to the center line, and then travels along the center line in a straight line on the first tunnel trolley 600. Figure 6 In section C, the transport vehicle 300 travels along a straight line near the edge on the second tunnel trolley 700, and then turns along a zigzag line on the first tunnel trolley 600 to the center line position. Figure 6 In section D, the transport vehicle 300 travels along a straight line near the right edge on the second tunnel trolley 700, and then travels along an arc to the left edge on the first tunnel trolley 600.
