Description

Technical Field

[0001] This utility model relates to a TBM trolley connecting component dismantling device, specifically a TBM trolley connecting component dismantling device for inclined shaft areas. Background Technology

[0002] During the shield tunneling construction of inclined shafts, in order to accommodate smaller radius turns or to inspect and maintain the main connecting components of the equipment, it is necessary to dismantle, maintain, or replace the connecting components of the equipment's rear-mounted trolley. Unlike straight tunnels, in inclined shafts, due to the equipment's own weight, all connecting components will experience stress under gravity. Dismantling connecting components under these conditions poses a significant safety risk. Therefore, before dismantling, the stress on the components must be relieved to ensure the structure is in a stable state.

[0003] Currently, due to the limited application of TBMs in inclined shafts in China, there are no relevant reference cases regarding the removal methods of connecting components under this working condition. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a TBM trolley connection component removal device for inclined shaft areas that can eliminate stress in the trolley connection components, has a simple structure, is easy to transport, and is applicable to the removal of most TBM connection components, in order to meet the needs of TBM trolley connection component removal in areas with steep inclines.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A device for dismantling TBM trolley connection components in an inclined shaft area includes at least two cylinder bases for connecting to the trolley column and a cylinder for connecting to the cylinder bases on adjacent trolleys. Each cylinder includes a cylinder barrel and a piston rod, with one end of the piston rod slidably mounted inside the cylinder barrel and the other end extending out of the cylinder barrel. The cylinder has a first state and a second state.

[0007] In the first state, the cylinder is not under force, and the piston rod extends out of the cylinder.

[0008] In the second state, the hydraulic cylinder bears the tension between the TBM carriages, the piston rod remains inside the cylinder, and the TBM's rear carriage is tightened.

[0009] Preferably, the cylinder base is a clamp-type cylinder base, which includes two opposing ring blocks. The two ring blocks are detachably connected as a whole, and a trolley column clamping space is formed within the two ring blocks. A cylinder connecting seat is provided on the two ring blocks.

[0010] Preferably, multiple sets of bolt holes are provided opposite to each other on the two ring blocks, and high-strength bolts are used to connect them through the bolt holes.

[0011] Preferably, when the hydraulic cylinders are connected, the cylinder barrel is connected to the hydraulic cylinder connecting seat on one trolley, and the piston rod is connected to the hydraulic cylinder connecting seat on another trolley.

[0012] Preferably, the hydraulic cylinder and the hydraulic cylinder connecting seat are connected by a pin.

[0013] Preferably, ribs are provided on the outer side of the ring block to enhance structural rigidity.

[0014] Preferably, the segmented splicing position of the ring hoop is provided with a joint, and a rubber gasket is provided on the joint to improve the tightness of the connection between the ring hoop segments.

[0015] Preferably, the ring blocks are provided with lifting lugs to facilitate lifting and transportation during operation.

[0016] Preferably, strain gauges are provided on the inner wall of the ring block under pressure, which can monitor the stress changes of the component in real time during use.

[0017] Preferably, the shape and size of the inner wall of the ring block are customized according to the form of the trolley column, so that it can fit tightly with the trolley column.

[0018] During installation and use, this utility model consists of two ring-shaped sections joined together to form a clamp-type hydraulic cylinder base. The inner wall of the clamp-type hydraulic cylinder base fits tightly against the column of the TBM's rear trolley. The clamp-type hydraulic cylinder bases installed on the front and rear trolleys are connected via hydraulic cylinders. After the hydraulic cylinder is installed, by retracting the stroke of the hydraulic cylinder piston rod, the hydraulic cylinder bears the tension between the TBM trolleys, thereby relieving the stress on the connecting components of the TBM's rear trolley and facilitating the removal of connecting components that need to be dismantled from the TBM's rear trolley.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] 1) The design of the clamp-type hydraulic cylinder base of this utility model avoids welding operations and facilitates quick assembly and disassembly during construction;

[0021] 2) The present invention provides a joint on the splicing surface of the ring hoop segments to enable rapid positioning and splicing of the ring hoop segments, and the rubber gaskets enable the ring hoop segments to fit more tightly during splicing;

[0022] 3) The design of the hydraulic cylinder of this utility model can accurately adjust the connection status of the trolley during use, thereby eliminating the stress on the trolley connection components;

[0023] 4) The strain gauges installed on the inner wall of the ring block of this utility model can monitor the stress on the clamp-type hydraulic cylinder base in real time, ensuring that the device is under normal stress and improving the safety of dismantling operations.

[0024] In summary, this utility model not only enables the rapid assembly and disassembly of connecting components between trolleys under special working conditions (sloping shafts with steep inclines), but also significantly reduces the safety risks during the dismantling of connecting components of the TBM's supporting trolleys, thus having significant practical value for the management and optimization of tunnel excavation projects.

[0048] The present invention will be further described below with reference to specific preferred embodiments, but this does not limit the scope of protection of the present invention.

[0049] In the description of this utility model, it should be noted that the terms "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0050] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0051] like Figure 1 - Figure 5 As shown, one embodiment of the TBM trolley connection component removal device for inclined shaft areas of this utility model consists of a clamp-type hydraulic cylinder base 100 and a hydraulic cylinder 200. The clamp-type hydraulic cylinder base 100 is installed in pairs on the columns of two TBM rear-mounted trolleys 300 connected front and rear. The inner wall of the clamp-type hydraulic cylinder base 100 is tightly fitted to the trolley column. The hydraulic cylinder 200 is installed between the clamp-type hydraulic cylinder bases 100 on the two TBM rear-mounted trolleys 300 connected front and rear, and the hydraulic cylinder 200 is parallel to the TBM rear-mounted trolley where the connection component 310 needs to be removed before installation.

[0052] Each clamp-type hydraulic cylinder base 100 is assembled from two opposing ring-shaped blocks 110. The ring-shaped blocks 110 are symmetrically arranged, forming a trolley column clamping space 117 within each block. A hydraulic cylinder connecting seat 112 is mounted on each of the two ring-shaped blocks 117. In this embodiment, multiple sets of bolt holes 114 are arranged opposite each other on the two ring-shaped blocks 110, and the connection is achieved by fastening high-strength bolts 130 through the bolt holes 114, thus avoiding welding during connection and facilitating rapid assembly and disassembly during construction. Obviously, the two ring-shaped blocks 110 of this invention are not limited to this connection method; other detachable connection methods conceived by those skilled in the art can also be used.

[0053] The hydraulic cylinder 200 includes a cylinder barrel 210 and a piston rod 220. One end of the piston rod 220 is slidably mounted inside the cylinder barrel 210, and the other end extends out of the cylinder barrel 210. When the hydraulic cylinder 200 is connected to the hydraulic cylinder base 100, the cylinder barrel 210 is connected to the hydraulic cylinder connecting seat 112 on one trolley via a pin 120, and the piston rod 220 is connected to the hydraulic cylinder connecting seat 112 on another trolley via a pin 120.

[0054] When this utility model is in use, the hydraulic cylinder 200 has a first state and a second state:

[0055] In the first state, the hydraulic cylinder 200 is not under force, and the piston rod 220 extends out of the cylinder 210;

[0056] In the second state, the hydraulic cylinder 200 bears the tension between the TBM carriages, the piston rod 220 is held inside the cylinder 210, and the TBM rear carriage is tightened.

[0057] When this utility model is used, the specific operation process of the hydraulic cylinder 200 is as follows:

[0058] After the clamp-type hydraulic cylinder base 100 is installed on the column of the front and rear TBM rear supporting trolleys 300, the two clamp-type hydraulic cylinder bases 100 are connected by hydraulic cylinder 200. When installing hydraulic cylinder 200, due to the large gap between the TBM rear supporting trolleys 300, hydraulic cylinder 200 is in the first state, and the piston rod 220 inside hydraulic cylinder 200 is in the extended state. After the hydraulic cylinder 200 is installed, the piston rod 220 is retracted by the external pump station. At this time, hydraulic cylinder 200 begins to gradually bear the tension between the TBM trolleys until the stress borne by the connecting component 310 to be removed from the TBM rear supporting trolley is completely eliminated. Then the piston rod 220 of hydraulic cylinder 200 no longer retracts. At this time, the connecting component 310 to be removed from the TBM rear supporting trolley can be removed.

[0059] like Figure 2 As shown, the splicing position of the ring block 110 is provided with a joint, and a rubber gasket 113 is provided on the joint to improve the tightness of the connection between the ring blocks.

[0060] like Figure 3 and Figure 4 As shown, in an optional embodiment of this utility model, a lifting lug 115 is also provided on the ring block 110 to facilitate material hoisting and transportation. In addition, strain gauges 116 are provided on the inner wall of the ring block 110 to monitor the stress changes of the clamp-type cylinder seat 100 in real time when it is under stress, thereby improving safety.

[0061] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can make many possible variations and modifications to the technical solution of this utility model, or modify it into equivalent embodiments with equivalent changes, without departing from the scope of the technical solution of this utility model. Therefore, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the content of the technical solution of this utility model should fall within the protection scope of the technical solution of this utility model.
