Description

Technical Field

[0001] This utility model relates to the field of tunnel construction technology, and more specifically, to a trolley used for tunnel construction. Background Technology

[0002] In the field of tunnel construction technology, a trolley is a series of rail-mounted mobile platform vehicles connected to the rear of a tunnel boring machine (TBM) or pipe jacking machine. The tunnel boring equipment operates in front, while the trolley follows closely behind. Acting as a mobile factory and command center, the trolley provides all necessary support to the tunnel boring equipment and handles various logistical issues arising during the excavation process. The trolley is typically mounted on rails and moved forward by the main machine.

[0003] Trolleys can be used to supply electric and hydraulic power, transport materials or waste such as tunnel segments and slag, mount various equipment such as ventilation and cooling systems, and serve as control rooms and personnel passages. Therefore, there are usually multiple trolleys.

[0004] In many tunnel construction scenarios, the excavation of side passages is involved, such as connecting passages in rail transit tunnels, escape passages in highway tunnels, and municipal utility tunnels or pumped storage tunnels. To excavate side passages, the tunneling equipment used for this purpose can be mounted on a trolley. Taking a shield tunneling machine as an example, to create a side passage between two main tunnels, a launching sleeve can be mounted on a trolley located in one main tunnel, and a receiving sleeve can be mounted on a trolley located in the other main tunnel. The launching and receiving sleeves are positioned correspondingly. The main unit of the tunneling machine excavates from the launching sleeve towards the receiving sleeve to excavate the side passage.

[0005] In existing technology, tunneling equipment can be used in conjunction with a jacking device. For the basic structure and working principle of the jacking device, please refer to the prior art disclosed in Chinese patents with publication numbers CN219910759U and CN218780355U. The jacking device can be connected and fixed to the sleeve or to the tunnel segments, and it exerts force to push the main unit of the tunneling equipment. Thus, the jacking device can push the main unit and / or the segments to be laid in the tunneling direction. It can be understood that the above-mentioned combination of tunneling equipment and jacking device can be used for lateral jacking, as well as longitudinal or inclined jacking.

[0006] In existing technology, the central axes of the tunneling equipment and jacking devices used for main tunnel excavation are parallel to the central axis of the main tunnel, and the jacking device can be supported and fixed to the inner wall of the tunnel. However, during the excavation of the side passage, the starting sleeve is mounted on a trolley, and the central axes of the starting sleeve, the main excavator, and the jacking device are all perpendicular to the central axis of the main tunnel, but parallel to the central axis of the side passage. In this case, the jacking device cannot be fixed to the periphery of the inner wall of the main tunnel.

[0007] Therefore, the existing technology has the following drawback: when using a trolley to mount the launching sleeve and receiving sleeve for bypass tunneling, the jacking device cannot be supported and fixed. Since the jacking device has a certain weight and needs to bear force when jacking towards the main machine, if it cannot be supported and fixed, it will lack a point of leverage, making stable jacking difficult.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] This invention provides a tunnel construction trolley for excavating side passages. Side passage excavation is necessary for various construction scenarios, such as connecting passages in rail transit tunnels, escape passages in highway tunnels, and municipal utility tunnels or pumped storage tunnels. To excavate side passages, a launching sleeve is mounted on a trolley located in one main tunnel, and a receiving sleeve is mounted on a trolley located in another main tunnel. The launching and receiving sleeves are positioned correspondingly. The main excavator of the tunneling equipment excavates from the launching sleeve towards the receiving sleeve, thus excavating the side passage.

[0026] The tunneling equipment on the starting side mainly includes a starting sleeve, a tunneling machine, and a jacking device. This equipment is carried and transported by a trolley. After the trolley carrying the tunneling equipment arrives at its destination, it is parked at the target location, and the starting sleeve on the trolley is fixed to the inner wall of the main tunnel. The tunneling machine then performs tunneling operations inside the starting sleeve. The jacking device and the tunneling machine can accommodate the segments to be assembled. The jacking device pushes the tunneling machine and the segments to be assembled towards the tunneling direction of the side passage to simultaneously complete tunneling and segment assembly. Thus, with the assistance of the jacking device, the tunneling machine can tunnel along the starting sleeve towards the receiving sleeve located in the main tunnel on the other side.

[0027] In the aforementioned process, the jacking equipment needs to provide jacking force to the tunnel boring machine and the tunnel segments. Therefore, the jacking equipment needs to have a stable point of leverage. For tunneling equipment used in the main tunnel construction, the jacking equipment can be fixed to the periphery of the inner wall of the main tunnel. However, in the case of side tunnel construction, the launching sleeve is mounted on a trolley, and the central axes of the launching sleeve, the main tunnel boring machine, and the jacking device are all perpendicular to the central axis of the main tunnel, but parallel to the central axis of the side tunnel. In this case, the jacking device cannot be fixed to the periphery of the inner wall of the main tunnel. Therefore, when using the method of mounting the launching sleeve and the receiving sleeve on a trolley for side tunnel excavation, the jacking device cannot be supported and fixed.

[0028] like Figure 1 and Figure 2 As shown, in order to solve the above problems, the trolley provided by this utility model includes: a trolley body and a support member 300. The trolley body is used to carry tunneling equipment and jacking equipment, and the support member 300 is provided on the trolley body; wherein, the support member 300 is used to abut against the jacking equipment to support the jacking equipment.

[0029] like Figure 1 and Figure 2 As shown, in this utility model, the trolley body mainly includes a base frame 100 and a column 200. Wheels 110 are provided under the base frame 100, and the wheels 110 can travel along the track. The tunneling equipment mainly includes a tunneling host, which has a tunneling cutterhead. The jacking equipment can achieve jacking through a device such as a hydraulic cylinder. When using a method of mounting the starting sleeve and receiving sleeve on the trolley for bypass tunneling, the jacking device can be supported and fixed by the support member 300. The jacking device has a certain weight, and when it jacks towards the main body of the tunneling equipment, the support member 300 can provide a point of leverage for the jacking device, thus supporting it and facilitating stable jacking, ensuring the smooth construction of the bypass tunnel.

[0030] To support the jacking equipment, the support component 300 needs to be in contact with the jacking equipment. The support component 300 can be directly connected to the jacking equipment, indirectly connected to the jacking equipment through other components, or simply in contact with the jacking equipment without being connected.

[0031] The shape of the support member 300 can be rod-shaped, column-shaped, or plate-shaped. Those skilled in the art can select and adjust the shape of the support member 300 according to the size of the trolley and the spatial arrangement.

[0032] The number of support components 300 can be one or more.

[0033] Regarding the installation position of the support member 300, if the support member 300 is connected to the jacking equipment, the support member 300 can be set at any position on the trolley body. If the support member 300 is only in contact with the jacking equipment but not connected, the support member 300 is preferably set on the side of the jacking equipment facing away from the tunneling equipment, so as to provide a point of force when the jacking equipment pushes the tunneling equipment.

[0034] Preferably, the support member 300 is used to hoist the jacking equipment so that the jacking equipment can move axially along the support member 300. For example, as shown... Figure 3 As shown, the support member 300 can be designed as a rod, installed between two columns 200. The support member 300 passes through the jacking equipment to lift it. This facilitates the installation of the jacking equipment and the alignment of it with the tunneling equipment. Due to the complex and variable working conditions in tunnel construction, if the jacking equipment is not perfectly aligned with the tunneling equipment during the excavation of the side passage, the jacking equipment can be moved along the support member 300 to change or fine-tune its position, thereby achieving alignment between the jacking equipment and the tunneling equipment.

[0035] As mentioned above, the trolley body mainly includes a base frame 100 and a column 200. The base frame 100 is used to carry the tunneling equipment and the jacking equipment, and the column 200 is set on the base frame 100 and encloses a space that can accommodate at least part of the jacking equipment.

[0036] The support member 300 can be mounted on the base frame 100 or on the column 200. For example, the support member 300 can be erected between at least two columns 200 and pass through and support the jacking device; or the support member 300 can be connected between the base frame 100 and the jacking device; or the support member 300 can be mounted on the base frame 100 and contact the side of the jacking device facing away from the tunneling equipment.

[0037] In one embodiment where the support member 300 is located on the base frame 100, the support member 300 can be disposed on the upper surface of the base frame 100, and its structure is a stiffener protruding upward relative to the surface of the base frame 100. The support member 300 is positioned on the side of the jacking equipment facing away from the tunneling equipment, and the support member 300 is in contact with the jacking equipment. Thus, the support member 300 can stop the jacking equipment, and when the jacking equipment applies a jacking force to the tunneling equipment, the support member 300 can serve as the point of force application for the jacking equipment.

[0038] In another embodiment where the support member 300 is located on the base frame 100, the support member 300 can be located on the upper surface of the base frame 100, and is connected to both the base frame 100 and the jacking equipment. The support member 300 can be located on either side of the jacking equipment. Thus, when the jacking equipment applies a jacking force to the tunneling equipment, the reaction force of the jacking force can be transmitted to the base frame 100 through the support member 300, with the support member 300 and the base frame 100 serving as the joint point of force application.

[0039] like Figure 2 As shown, in one embodiment where the support member 300 is provided on the column 200, a support member 300 can be connected between two columns located on the left and right sides of the jacking equipment.

[0040] In another embodiment where the support member 300 is located on the column 200, an even number of support members 300 arranged in pairs can be symmetrically arranged on the left and right sides of the jacking equipment, with each of the support members 300 on both sides connected to the two columns on the front and rear sides of the jacking equipment.

[0041] Preferably, such as Figure 4 As shown, the trolley body includes: an auxiliary support 600, which has a bent structure, with one end connected to the base frame 100 and the other end connected to the column 200; wherein, the auxiliary support 600 is used to assist in supporting the column 200.

[0042] Specifically, the auxiliary support 600 has an "L"-shaped right-angle bend structure, and each column is equipped with a matching auxiliary support 600. The auxiliary support 600 is used to support the column 200 to prevent the column 200 from deforming.

[0043] Preferably, such as Figure 3 As shown, the trolley body includes a back plate 700, which is connected to the column 200 and protrudes in the direction away from the accommodating space. The back plate 700 is used to abut against the inner wall of the tunnel.

[0044] Specifically, the backplate 700 has a crescent-shaped structure with an arc-shaped surface for contacting the tunnel wall, so that the backplate 700 can abut against the tunnel wall to keep the trolley and the facilities on the trolley, including the jacking equipment, stable.

[0045] Preferably, such as Figure 2As shown, the column 200 includes a first column 210 and a second column 220 arranged in pairs along the travel direction of the trolley. The trolley also includes a first support 510 and a second support (not shown in the figure), the first support 510 being mounted on the first column 210 and the second support being mounted on the second column 220. One end of the support member 300 is movably connected to the first column 210 via the first support 510, and the other end is movably connected to the second column 220 via the second support.

[0046] It should be noted that the second support has the same shape as the first support 510, and its installation position is symmetrical to that of the first support 510. The two cooperate with each other to support and fix the support member 300. By configuring the support member 300 to be movably connected to the first column 210 and the second column 220 respectively, the installation and disassembly of the support member 300 can be facilitated. For example, the support member 300 can be slidably connected between the first support 510 and the second support, or it can be snapped into the first support 510 and the second support respectively.

[0047] Preferably, such as Figure 4 and Figure 5 As shown, the first support 510 has a first groove 511, and the second support has a second groove (not shown in the figure). The support member 300 can slide along the first groove 511 and the second groove.

[0048] It should be noted that the shape of the second slide groove is the same as that of the first slide groove 511, and the installation position is symmetrical to that of the first slide groove 511. The two cooperate with each other, and the support member 300 can slide along the first slide groove 511 and the second slide groove.

[0049] It is understandable that, in order to achieve a sliding connection between the support member 300 and the first support 510 and the second support, the support member 300 may have a sliding piece that matches the shape of the first sliding groove 511 and the second sliding groove.

[0050] like Figure 1 and Figure 2 As shown, the jacking equipment specifically includes a power element 410 and a power element bracket 420 for supporting the power element 410. The support member 300 abuts against the power element bracket 420. The power element 410 is preferably a hydraulic cylinder, and there can be one or more of them. When there are multiple power elements 410, they are distributed on the power element bracket 420. The power element is used to provide jacking force to the tunneling equipment, and the power element bracket 420 can support and fix one or more power elements 410.

[0051] like Figure 3As shown, the power element support 420 includes a first support portion 420a and a second support portion 420b. The first support portion 420a and the second support portion 420b are arranged front and rear along the tunneling direction of the tunneling equipment. The power element 410 is supported through the first support portion 420a and the second support portion 420b, and at least a portion of the support member 300 passes between the first support portion 420a and the second support portion 420b.

[0052] Specifically, the first support portion 420a and the second support portion 420b are both flat plates, arranged parallel to each other in the vertical direction to support and fix the front and rear sides of the power element 410 respectively. The support member 300 passes between the first support portion 420a and the second support portion 420b, and is limited and stopped by the first support portion 420a and the second support portion 420b. This allows the support member 300 to be used for hoisting the jacking equipment, while also reducing the installation space required for the support member 300, making the space arrangement of the trolley body more compact while providing a fulcrum for the jacking equipment.

[0053] Preferably, such as Figure 3 As shown, the power component bracket 420 also includes a connecting part, and the first support part 420a and the second support part 420b are connected by the connecting part; wherein, the support member 300 contacts the connecting part so that the support member 300 can suspend the power component bracket 420.

[0054] Preferably, the first support portion 420a, the second support portion 420b, and the connecting portion are formed as an integral structure. The connecting portion can provide support for the support member 300 from the bottom of the support member 300, which can both ensure that the jacking equipment is stably hoisted and ensure that the jacking equipment has a certain amount of room to move so as to adjust its position and align it with the tunneling equipment.

[0055] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
