Description

Technical Field

[0001] This invention relates to the field of tunnel construction, and in particular to a central partition wall assembly device and a tunnel boring machine. Background Technology

[0002] During tunnel excavation, a central partition wall is typically used to divide the tunnel into two lanes. The central partition wall is generally composed of prefabricated central partition wall blocks. To install the central partition wall blocks quickly and efficiently, a dedicated installation device for the prefabricated central partition wall blocks has been developed. Due to the limited space inside the tunnel and the generally heavy weight of the installation device, how to quickly and accurately move the installation device to the installation position of the central partition wall blocks is an important research topic in this field.

[0003] In existing technologies, the installation device for prefabricated central partition walls is typically constructed by installing tracks at the bottom of the device or by laying a track within a speed adjustment mechanism. This allows the device to roll forward via the tracks or move along the track. For example, the patent with publication number "CN202202875U" entitled "Special Chassis for Construction Machinery of Central Partition Walls in Tunnels" uses tracks to move along the tunnel axis. Meanwhile, the patent with publication number "CN112761664A" entitled "An Installation Device for Prefabricated Central Partition Walls in Shield Tunnels" uses wheels that travel on a track to move the prefabricated central partition wall installation device to the assembly position.

[0004] However, both installing tracks at the bottom of the precast block installation device for the central partition wall and laying tracks inside the tunnel are costly. Summary of the Invention

[0005] To address at least one of the problems mentioned in the background art, the present invention provides a partition wall assembly device and a tunnel boring machine with low cost.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] In a first aspect, the present invention provides a partition wall assembly device, including a vehicle body, track wheels, a support assembly and a clamping assembly. The vehicle body is provided with an installation unit for assembling the partition wall. The track wheels are located at the bottom of the vehicle body and are configured to travel along the track.

[0008] The support assembly is installed on the vehicle body, and the support assembly includes a support arm. The support arm can telescopically move relative to the vehicle body to support the ground or retract into the vehicle body. When the support arm is supported on the ground, the track-mounted wheels are disengaged from the track.

[0009] The clamping assembly is disposed on the vehicle body and is movable relative to the vehicle body in the extension direction of the track. The clamping assembly is configured to clamp the track and move it toward the joint of the central partition wall at the front of the vehicle body when the support arm is supported on the ground.

[0010] As an optional implementation, the support assembly also includes a connecting frame disposed on the side of the vehicle body, and the first end of the support arm is hinged to the connecting frame via a vertical pivot to allow the support arm to rotate to different sides of the vehicle body, and the second end of the support arm is used to support the ground.

[0011] As an optional implementation, the support assembly also includes a locking element that locks the support arm to the connecting frame when the support arm rotates around the connecting frame to a target position for supporting the ground.

[0012] As an optional implementation, the support arm includes an outer sleeve, an inner sleeve, a first drive cylinder, and a support base, with the side wall of the outer sleeve and the connecting frame hinged together.

[0013] Both the outer sleeve and the inner sleeve have an open end and a closed end. The outer sleeve is fitted over the outer side of the inner sleeve, and the open end of the outer sleeve and the open end of the inner sleeve are positioned opposite each other.

[0014] The first drive cylinder is located in the inner sleeve and abuts between the closed end of the outer sleeve and the closed end of the inner sleeve, so as to drive the inner sleeve and the outer sleeve to move relative to each other through the extension and retraction of the first drive cylinder; the support base is fixedly connected to the bottom of the inner sleeve.

[0015] As an optional implementation, a second drive cylinder is also included. One end of the second drive cylinder is fixed to the vehicle body, and the other end of the second drive cylinder is connected to the clamping assembly so as to drive the clamping assembly on the vehicle body to move along the extension direction of the track by the extension and retraction of the second drive cylinder.

[0016] As an optional implementation, the clamping assembly also includes a lifting unit and a clamp for clamping the track. The lifting unit is movably disposed at one end of the second drive cylinder, and the clamp is connected to the lifting unit so that the clamp can be moved vertically by the lifting unit.

[0017] As an optional implementation, the lifting unit includes four hinged links and a third drive cylinder. The four links form a parallelogram mechanism, and the vehicle body and the clamp are respectively connected to two opposite links among the four links. The two ends of the third drive cylinder are connected to the diagonal positions of the parallelogram mechanism so as to drive the clamp to move in the vertical direction by extending and retracting the third drive cylinder.

[0018] As an optional implementation, there are at least two clamping assemblies, and the at least two clamping assemblies are respectively disposed above the two rails of the track along the width direction of the track.

[0019] As an alternative implementation, there are up to four support components, which are respectively disposed around the perimeter of the vehicle body.

[0020] In a second aspect, the present invention also provides a tunnel boring machine, including the central partition wall assembly device of any one of the first aspects.

[0021] The partition wall assembly device provided by the present invention includes a vehicle body, track-running wheels, a support assembly, and a clamping assembly. The vehicle body is provided with an installation unit for assembling the partition wall. The track-running wheels are located at the bottom of the vehicle body and are configured to travel along the track. The support assembly is located on the vehicle body and includes a support arm that can extend and retract relative to the vehicle body to support the ground or retract into the vehicle body. When the support arm is supported on the ground, the track-running wheels are disengaged from the track. The clamping assembly is located on the vehicle body and is movably arranged relative to the vehicle body along the extension direction of the track. The clamping assembly is configured to clamp the track and move it toward the partition wall splicing point in front of the vehicle body when the support arm is supported on the ground. When in use, the partition wall assembly device provided by this invention can roll forward along a short track using the track-moving wheels set at the bottom of the vehicle body. When it rolls to one end of the track, the support arm on the vehicle body can be extended and supported on the ground, so that the track-moving wheels can temporarily detach from the track. Then, the clamping component set on the vehicle body can clamp the track below and move it forward. After the track is repositioned, the support arm is readjusted and retracted, so that the track-moving wheels fall back onto the track. With this method of movement, there is no need to lay a complete track in the tunnel. Only a short movable track is needed to cooperate with the partition wall assembly device, which greatly reduces the construction cost. Attached Figure Description

[0051] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0052] In this application, the terms “upper,” “lower,” “left,” “right,” “front,” “back,” “top,” “bottom,” “inner,” “outer,” “vertical,” “horizontal,” “lateral,” and “longitudinal” indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings. These terms are primarily for the purpose of better describing the invention and its embodiments and are not intended to limit the indicated devices, elements, or components to having a specific orientation or to be constructed and operated in a specific orientation.

[0053] Furthermore, in addition to indicating direction or positional relationship, some of the aforementioned terms may also have other meanings. For example, the term "above" may also be used in certain situations to indicate a dependency or connection. Those skilled in the art can understand the specific meaning of these terms in this invention based on the specific circumstances.

[0054] Furthermore, the terms "installation," "setup," "equipped with," "connection," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral structure; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium, or an internal connection between two devices, components, or parts. Those skilled in the art can understand the specific meaning of these terms in this invention based on the specific circumstances.

[0055] Furthermore, the terms "first," "second," etc., are primarily used to distinguish different devices, elements, or components (which may be the same or different in specific type and construction), and are not intended to indicate or imply the relative importance or quantity of the indicated devices, elements, or components. Unless otherwise stated, "a plurality of" means two or more.

[0056] In existing technologies, the installation device for prefabricated central partition walls is typically installed with a track at the bottom or a track is laid in the tunnel, allowing the device to roll forward or move along the track. However, both installing a track at the bottom of the installation device and laying a track in the tunnel are costly.

[0057] In view of this, the present invention provides a partition wall assembly device, including a vehicle body, track-mounted wheels, a support assembly, and a clamping assembly. The vehicle body is equipped with an installation unit for assembling the partition wall. The track-mounted wheels are located at the bottom of the vehicle body and are configured to travel along a track. The support assembly is located on the vehicle body and includes a support arm that can extend and retract relative to the vehicle body. The clamping assembly is located on the vehicle body and is movable relative to the vehicle body along the extension direction of the track. During construction, the track-mounted wheels at the bottom of the vehicle body can roll forward along a short track. When they reach one end of the track, the support arm on the vehicle body can extend and support the ground, temporarily detaching the track-mounted wheels from the track. Then, the clamping assembly on the vehicle body can clamp the track below and move it forward. After the track is repositioned, the support arm can be readjusted and retracted, allowing the track-mounted wheels to fall back onto the track. With this method of movement, it is not necessary to lay a complete track inside the tunnel; only a short, movable track is needed to cooperate with the partition wall assembly device, greatly reducing construction costs.

(See also...) Figures 1 to 10This invention provides a partition wall assembly device 100, including a vehicle body 110, track-mounted wheels 120, a support assembly 130, and a clamping assembly 140. The vehicle body 110 is provided with an installation unit for assembling the partition wall. The track-mounted wheels 120 are located at the bottom of the vehicle body 110 and are configured to travel along a track 200. The support assembly 130 is located on the vehicle body 110 and includes a support arm 131. The support arm 131 is telescopically movable relative to the vehicle body 110 to support the ground or retract into the vehicle body 110. When the support arm 131 is supported on the ground, the track-mounted wheels 120 disengage from the track 200. The clamping assembly 140 is located on the vehicle body 110 and is movably disposed relative to the vehicle body 110 in the extension direction along the track 200. The clamping assembly 140 is configured to clamp the track 200 and move it toward the partition wall assembly point in front of the vehicle body 110 when the support arm 131 is supported on the ground.

[0059] When in use, the partition wall assembly device 100 provided in this embodiment of the invention can roll forward along a short track 200 via the track-walking wheels 120 provided at the bottom of the vehicle body 110. When it rolls to one end of the track 200, the support arm 131 on the vehicle body 110 can be extended and supported on the ground, so that the track-walking wheels 120 are temporarily detached from the track 200. Then, the clamping component 140 provided on the vehicle body 110 clamps up the track 200 below and moves it forward. After the track 200 is repositioned, the support arm 131 is readjusted to retract, so that the track-walking wheels 120 fall back onto the track 200. With this method of movement, it is not necessary to lay a complete track 200 in the tunnel. Only a short movable track 200 is needed to cooperate with the partition wall assembly device 100, which greatly reduces the construction cost.

[0060] In the above embodiments, the support assembly 130 may further include a connecting frame 132, which is disposed on the side of the vehicle body 110. The first end of the support arm 131 is hinged to the connecting frame 132 via a vertical pivot 133, so that the support arm 131 can rotate to different sides of the vehicle body 110. The second end of the support arm 131 is used to support the ground. Before supporting the support arm 131 on the ground, the support arm 131 can be rotated around the connecting frame 132 to the outside of the track 200 to avoid affecting the forward movement of the track 200 when the support arm 131 is supported on the inside of the track 200. Specifically, there may be up to four support assemblies 130, which are respectively disposed around the perimeter of the vehicle body 110.

[0061] like Figure 2 and Figure 7As shown in the above embodiment, the support assembly 130 may further include a locking member 134. When the support arm 131 rotates around the connecting frame 132 to a target position for supporting the ground, the locking member 134 locks the support arm 131 to the connecting frame 132. The target position is generally a location outside the track 200. When the support arm 131 rotates around the connecting frame 132 to the outside of the track 200, the locking member 134 can lock the support arm 131 to the connecting frame 132 to prevent the support arm 131 from swaying relative to the connecting frame 132 during the movement of the track 200. Specifically, the locking member 134 can be a pin that passes through both the support arm 131 and the connecting frame 132, thereby limiting the relative rotation between the support arm 131 and the connecting frame 132.

[0062] like Figure 8 As shown, in the above embodiment, the support arm 131 may include an outer sleeve 1311, an inner sleeve 1312, a first drive cylinder 1313, and a support base 1314. The side wall of the outer sleeve 1311 and the connecting frame 132 are hinged. Both the outer sleeve 1311 and the inner sleeve 1312 have an open end and a closed end. The outer sleeve 1311 is sleeved on the outside of the inner sleeve 1312, and the open end of the outer sleeve 1311 and the open end of the inner sleeve 1312 are arranged opposite to each other. The first drive cylinder 1313 is disposed in the inner sleeve 1312 and abuts between the closed end of the outer sleeve 1311 and the closed end of the inner sleeve 1312, so as to drive the inner sleeve 1312 and the outer sleeve 1311 to move relative to each other through the extension and retraction of the first drive cylinder 1313. The support base 1314 is fixedly connected to the bottom of the inner sleeve 1312.

[0063] In the above embodiments, the partition wall assembly device 100 may further include a second drive cylinder 150. The second drive cylinder 150 is horizontally arranged on the vehicle body 110. One end of the second drive cylinder 150 is fixed to the vehicle body 110, and the other end of the second drive cylinder 150 is connected to the clamping assembly 140. When the clamping assembly 140 clamps the lower track 200, the second drive cylinder 150 drives the clamping assembly 140 on the vehicle body 110 to move along the extension direction of the track 200 through its own extension and retraction, thereby moving the track 200 forward.

[0064] like Figure 9 and Figure 10As shown in the above embodiment, the clamping assembly 140 may further include a lifting unit 141 and a clamp 142 for clamping the track 200. The lifting unit 141 is movably disposed at one end of the second drive cylinder 150, and the clamp 142 is connected to the lower end of the lifting unit 141. The clamp 142 can clamp the track 200 on the ground, and the lifting unit 141 can lift the clamp 142 and the track 200 clamped by the clamp 142 together to a certain height, so that the track 200 is lifted off the ground as much as possible. The second drive cylinder 150 drives the lifting unit 141 to move back and forth, thereby moving the track 200 forward.

[0065] In the above embodiments, the lifting unit 141 may specifically include four connecting rods hinged at both ends and a third driving cylinder. The four connecting rods form a parallelogram mechanism, and the vehicle body 110 and the clamp 142 are respectively connected to two opposite connecting rods among the four connecting rods. The two ends of the third driving cylinder are connected to the diagonal positions of the parallelogram mechanism so as to drive the clamp 142 to move in the vertical direction through the extension and retraction of the third driving cylinder.

[0066] In the above embodiments, there may be at least two clamping components 140, and at least two clamping components 140 are respectively arranged above the two rails of the track 200 along the width direction of the track 200. Specifically, there may be two clamping components 140, which are arranged on both sides of the lower end of the vehicle body 110, and each clamping component 140 clamps one rail of the track 200. Correspondingly, there may also be two second drive cylinders 150, each of which drives one clamping component 140 to move. When the clamping component 140 clamps the track 200 and lifts it off the ground, the track 200 can be deflected to a certain extent by the asynchronous drive of the two second drive cylinders 150 (the extension and retraction lengths of the two second drive cylinders 150 are different at the same time) to adapt to the tunnel environment with certain curves.

[0067] The partition wall assembly device 100 provided in this embodiment of the invention includes a vehicle body 110, track-mounted wheels 120, a support assembly 130, and a clamping assembly 140. The vehicle body 110 is provided with an installation unit for assembling the partition wall. The track-mounted wheels 120 are located at the bottom of the vehicle body 110 and are configured to travel along the track 200. The support assembly 130 is located on the vehicle body 110 and includes a support arm 131. The support arm 131 can extend and retract relative to the vehicle body 110 to support the ground or retract to the vehicle body 110. When the support arm 131 is supported on the ground, the track-mounted wheels 120 disengage from the track 200. The clamping assembly 140 is located on the vehicle body 110 and is movably disposed relative to the vehicle body 110 in the extension direction along the track 200. The clamping assembly 140 is configured to clamp the track 200 and move it toward the partition wall splicing point in front of the vehicle body 110 when the support arm 131 is supported on the ground. When in use, the partition wall assembly device 100 provided in this embodiment of the invention can roll forward along a short track 200 via the track-walking wheels 120 provided at the bottom of the vehicle body 110. When it rolls to one end of the track 200, the support arm 131 on the vehicle body 110 can be extended and supported on the ground, so that the track-walking wheels 120 are temporarily detached from the track 200. Then, the clamping component 140 provided on the vehicle body 110 clamps up the track 200 below and moves it forward. After the track 200 is repositioned, the support arm 131 is readjusted and retracted, so that the track-walking wheels 120 fall back onto the track 200. With this method of movement, it is not necessary to lay a complete track 200 in the tunnel. Only a short movable track 200 is needed to cooperate with the partition wall assembly device 100 to make the vehicle body 110 move forward continuously, which greatly reduces the construction cost.

[0068] Furthermore, this embodiment of the invention also provides a tunnel boring machine, including a central partition wall assembly device 100 of any of the above embodiments. The central partition wall assembly device 100 includes a vehicle body 110, track wheels 120, a support assembly 130, and a clamping assembly 140. The vehicle body 110 is provided with an installation unit for assembling the central partition wall. The track wheels 120 are disposed at the bottom of the vehicle body 110. The support assembly 130 is disposed on the vehicle body 110 and includes a support arm 131, which can extend and retract relative to the vehicle body 110. The clamping assembly 140 is disposed on the vehicle body 110 and is movably disposed relative to the vehicle body 110 along the extension direction of the track 200. During construction, the track-moving wheels 120 at the bottom of the vehicle body 110 can roll forward along a short track 200. When it rolls to one end of the track 200, the support arm 131 on the vehicle body 110 can be extended to support the ground, so that the track-moving wheels 120 can temporarily detach from the track 200. Then, the clamping assembly 140 on the vehicle body 110 can clamp the track 200 below and move it forward. After the track 200 is repositioned, the support arm 131 can be readjusted to retract, so that the track-moving wheels 120 fall back onto the track 200. With this method of movement, it is not necessary to lay a complete track 200 in the tunnel. Only a short movable track 200 is needed to cooperate with the central partition wall assembly device 100, which greatly reduces the construction cost and improves the cost-effectiveness of the tunnel boring machine.

[0069] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them. Although the present invention 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 or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
