Description

Technical Field

[0001] This utility model relates to the field of tunnel construction technology, and in particular to a bracket device. Background Technology

[0002] During tunnel construction, especially in bypass tunnels or small-diameter tunnels, the tunneling machine (TBM) needs to be hoisted and inserted into the sleeve assembly to ensure coaxial alignment between the sleeve assembly and the TBM. However, the TBM is heavy and needs to avoid collisions and impacts with the sleeve assembly. Using hoisting equipment for hoisting and assembly not only requires more equipment and a larger construction space, but also makes it difficult to control the hoisting position, leading to technical problems such as collisions, repeated adjustments to the hoisting position, and long assembly time. Therefore, improvements are needed. Utility Model Content

[0003] To overcome the problems existing in the related technologies, this utility model provides a bracket device to solve the technical problems of high assembly difficulty of the sleeve device and the tunneling host and large required operating space.

[0004] According to a first aspect of the present utility model, a bracket device is provided for assembling a tunneling host and a sleeve device. The bracket device includes a translation bracket, a locking member, a track mechanism fixed to the translation bracket, and a jacking mechanism slidably connected to the track mechanism. The translation bracket is provided with two sets of protruding support brackets, and a support space is formed between the two sets of support brackets. The support space is used to support the limiting sleeve device. The track mechanism extends toward the support space to support the tunneling host. The locking member locks the jacking mechanism to the track mechanism and / or the translation bracket. The jacking mechanism is used to push the tunneling host toward the sleeve device.

[0005] In one embodiment, along the length of the track mechanism, the track mechanism and / or the translation bracket are provided with spaced locking holes. The jacking mechanism is gradually locked into one or more of these locking holes by the locking member, so that the jacking mechanism gradually advances the tunneling host along the length of the track mechanism.

[0006] In one embodiment, the track mechanism includes two parallel sliding tracks spaced apart, the two sliding tracks jointly supporting the tunneling host, and the jacking mechanism sliding on the sliding tracks.

[0007] In one embodiment, the two sliding tracks are inclined toward the center.

[0008] In one embodiment, the jacking mechanism includes at least one sliding frame assembly and a telescopic power assembly mounted on the sliding frame assembly. The sliding frame assembly is locked to the locking hole by the locking member, and at least a portion of the tunneling host is located within the telescopic range of the telescopic power assembly.

[0009] In one embodiment, the telescopic power assembly is configured as a hydraulic cylinder, an electric push rod, or a screw; the sliding frame assembly consists of two components, each sliding on a corresponding sliding track; and the locking hole is located on the sliding track.

[0010] In one embodiment, the translation bracket includes two symmetrical sets of bottom frames, each bottom frame including a reinforcing beam and a reinforcing frame fixed to one side of the reinforcing beam, the support bracket being fixed to the reinforcing frame, the two sets of reinforcing beams being located between the two sets of support brackets, and the track mechanism being mounted on the reinforcing beam.

[0011] In one embodiment, the two sets of reinforcing beams are connected by a hinge mechanism.

[0012] In one embodiment, the support bracket includes an inclined support wall, and the distance between the support spaces formed by the inclined support walls of two sets of support brackets gradually decreases.

[0013] In one embodiment, a power control mechanism is included, which is mounted on the translation bracket and connected to the jacking mechanism.

[0014] The technical solution provided by the embodiments of this utility model can include the following beneficial effects: the support bracket centers and limits the sleeve device, thereby keeping the position of the sleeve device unchanged. The track mechanism supports the tunneling machine, and the centerline of the tunneling machine and the center of the sleeve device are basically coincident, so that the tunneling machine slides along the track mechanism into the matching position of the sleeve device. The jacking mechanism slides along the track mechanism, and as the tunneling machine moves, the jacking mechanism can gradually adjust its connection position with the track mechanism, so that the jacking mechanism can gradually push the tunneling machine into the sleeve device. The construction space is small and the pushing effect is high, avoiding the impact risk of the tunneling machine and the sleeve device. Attached Figure Description

Detailed Implementation

[0022] In the accompanying drawings of this utility model, the same or similar reference numerals correspond to the same or similar components. In the description of this utility model, it should be understood that if terms such as "upper," "lower," "left," "right," "inner," and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, they 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. Therefore, the terms used to describe positional relationships in the drawings are only for illustrative purposes and should not be construed as limiting this utility model. For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.

[0023] like Figures 1 to 3 As shown, this utility model provides a bracket device for assembling the tunneling host 70 and the sleeve device 60, so as to improve the assembly efficiency and accuracy of the tunneling host 70 and the sleeve device 60 and reduce the assembly difficulty.

[0024] The bracket device includes a translation bracket 10, a locking element 43, a track mechanism 20, and a jacking mechanism 40. The translation bracket 10 has a frame structure and includes a bottom frame 11 at the bottom and support brackets 12 protruding from opposite sides of the bottom frame 11. A support space is formed between the two sets of support brackets 12. The support brackets 12 can define the outer peripheral wall of the sleeve device 60. For example, the support brackets 12 include inclined support walls 121, and the distance between the support spaces formed by the inclined support walls 121 of the two sets of support brackets 12 gradually decreases. The inclined support walls 121 form a V-shaped support space, which can support the sleeve device 60 and automatically align it.

[0025] Furthermore, the bottom frame 11 and the support bracket 12 jointly support the sleeve device 60. The translation bracket 10 includes two symmetrical sets of bottom frames 11, which are directly locked together. For example, the two sets of bottom frames 11 are locked with fasteners to facilitate disassembly, transportation, and assembly. Alternatively, the two sets of bottom frames 11 are connected by a connecting mechanism to form a single unit, thereby improving the overall structural strength. For example, the two sets of bottom frames 11 are welded together using connecting pipes to form an integral frame structure. Furthermore, the two sets of bottom frames 11 are connected by a hinge mechanism 13, allowing them to rotate and fold relative to each other, reducing transportation dimensions.

[0026] In one embodiment, the bottom frame 11 includes a reinforcing beam 111 and a reinforcing frame 112 fixed to one side of the reinforcing beam 111, with a support bracket 12 fixed to the reinforcing frame 112. Two sets of reinforcing beams 111 are located between two sets of support brackets 12. Preferably, the height of the reinforcing beam 111 is greater than the height of the reinforcing frame 112, and a support groove is formed between the two reinforcing beams 111.

[0027] like Figure 2 , Figure 3 and Figure 5 As shown, in a preferred embodiment, the translation bracket 10 is composed of two symmetrically distributed parts, wherein the bottom frame 11 is connected by a hinge mechanism 13, which enables foldable movement while maintaining the integrity of the translation bracket 10, thereby reducing the overall volume and facilitating handling.

[0028] Optionally, the hinge mechanism 13 is provided with two or more sets of connection parts to achieve multi-point connection of the bottom frame 11. The hinge mechanism 13 includes a first connector 131, a second connector 133, and a hinge shaft 132. The first connector 131 is fixedly connected to a set of reinforcing beams 111, and the second connector 133 is fixedly connected to another set of reinforcing beams 111. The first connector 131 and the second connector 133 are connected by the hinge shaft 132 to form a hinged connection.

[0029] In a preferred embodiment, the first connecting frame is part of the reinforcing frame 112, that is, the first connecting frame is an extension of the crossbeam of the reinforcing frame 112 to form an integral structural strength. Based on the same principle, the second connecting member 133 is part of another reinforcing frame 112.

[0030] More preferably, the top of the reinforcing beam 111 located in the area of ​​the support bracket 12 is provided with an inclined support surface 1112. The two sets of support brackets 12 and the two sets of reinforcing beams 111 cooperate to support and limit the lower area of ​​the sleeve device 60, thereby enabling the positioning of the center position of the sleeve device 60, and facilitating the adjustment of the center position of the tunneling host 70 and the center position of the sleeve device 60 to basically coincide.

[0031] The track mechanism 20 is fixed to the translation bracket 10 and extends toward the support space to support the tunneling machine 70. Specifically, the track mechanism 20 is installed on the reinforcing beam 111 to adjust the centerline height of the tunneling machine 70.

[0032] Preferably, the track mechanism 20 includes two parallel sliding tracks 21 spaced apart, which together support the tunneling host 70. Each sliding track 21 is installed on a corresponding reinforcing beam 111, which can raise the centerline position of the tunneling host 70 so that the centerline of the tunneling host 70 and the centerline of the sleeve device 60 are basically on the same straight line.

[0033] Furthermore, the two sliding rails 21 are inclined towards the center. This center direction is the symmetrical center plane of the two sliding rails 21. The inclination of the two sliding rails 21 towards the center can provide radial support from the tunneling machine 70, improving the direction of the supporting force of the sliding rails 21 on the tunneling machine 70, so that each sliding rail 21 bears almost no pressure and the lateral force it experiences is small or even non-existent.

[0034] Optionally, the portion of the reinforcing beam 111 used for mounting the sliding rail 21 is provided with an mounting ramp 1111, which allows for easy adjustment of the mounting angle of the sliding rail 21.

[0035] The jacking mechanism 40 is slidably connected to the track mechanism 20, and is used to push the tunneling host 70 toward the sleeve device 60. The jacking mechanism 40 is a power control mechanism 30. For example, the jacking mechanism 40 includes a hydraulic cylinder or an electric push rod, and the telescopic movement of the telescopic end pushes the tunneling host 70 to move. Alternatively, the jacking mechanism 40 includes a screw, and by rotating the screw, the tunneling host 70 can be pushed to move.

[0036] The jacking mechanism 40 and the track mechanism 20 are slidably connected and locked in position by a locking member 43, which locks the jacking mechanism 40 to the track mechanism 20 and / or the translation bracket 10. After the locking member 43 completes the position locking of the jacking mechanism 40, the jacking mechanism 40 pushes the tunneling host 70 to move the telescopic length. Then, after the telescopic end of the jacking mechanism 40 retracts, the locking member 43 releases the lock on the jacking mechanism 40. The jacking mechanism 40 is then moved along the track mechanism 20 to a secondary pushing position close to the tunneling host 70, and the locking member 43 locks the jacking mechanism 40 to the track mechanism 20 and / or the translation bracket 10, allowing the jacking mechanism 40 to perform a secondary pushing. The above steps are repeated until the assembly of the tunneling host 70 and the sleeve device 60 is completed.

[0037] Based on the locking requirements of the jacking mechanism 40 and the locking member 43, multiple locking holes 22 are spaced apart along the length of the track mechanism 20; or, multiple locking holes 22 are spaced apart on the translation bracket 10; or, both the track mechanism 20 and the translation bracket 10 are provided with locking holes 22, and the jacking mechanism 40 is gradually locked to one or more of the locking holes 22 by the locking member 43, so that the jacking mechanism 40 gradually advances the tunneling host 70 along the length of the track mechanism 20.

[0038] like Figures 3 to 5 As shown, in one embodiment, the jacking mechanism 40 includes at least one sliding frame assembly 41 and a telescopic power assembly 42 mounted on the sliding frame assembly 41. The sliding frame assembly 41 is locked to the locking hole 22 by a locking member 43, and at least a portion of the tunneling host 70 is located within the telescopic range of the telescopic power assembly 42. The telescopic power assembly 42 is configured as a hydraulic cylinder, an electric push rod, or a screw.

[0039] The locking holes 22 are holes that are spaced apart along the length of the sliding track 21. The sliding frame assembly 41 is provided with a plug hole. The locking member 43 passes through the plug hole and locks to the locking holes 22 to lock the position of the sliding frame assembly 41.

[0040] Preferably, the locking member 43 passes through the sliding track 21 and is spaced apart along the middle part of the sliding track 21. The sliding frame assembly 41 slides on the sliding track 21 and is locked to the sliding track 21, with small torque and convenient operation.

[0041] In an optional embodiment, the jacking mechanism 40 can slide synchronously on two sliding tracks 21. The jacking mechanism 40 includes a timing frame and a telescopic member installed on the timing frame. The telescopic member can push the tunneling host 70.

[0042] In a preferred embodiment, two sliding frame assemblies 41 are provided, each sliding on a corresponding sliding track 21, and a locking hole 22 is provided on the sliding track 21. The sliding frame assembly 41 slides on the corresponding sliding track 21, wherein protruding cantilever arms are provided on both sides of the sliding frame assembly 41, a plug hole passes through the two cantilever arms, and a locking member 43 passes through the plug hole and the locking hole 22, wherein the two ends of the locking member 43 are limited at the two cantilever arms.

[0043] Furthermore, the locking elements 43 on the sliding track 21 are evenly distributed, and the cantilever is provided with two insertion holes. The distance between the two insertion holes is the same as the distance between the locking holes 22, so that the locking elements 43 can be inserted into the two insertion holes simultaneously. Optionally, the locking elements 43 are insertion pins or U-shaped pins.

[0044] In one embodiment, the bracket device includes a power control mechanism 30 mounted on the translation bracket 10, and the power control mechanism 30 is connected to the jacking mechanism 40. The power control mechanism 30 is disposed on the translation bracket 10 and constitutes an integral movable part, which has a high degree of integration, requires no additional installation space, and is highly convenient to operate.

[0045] Based on the above embodiments, the bracket device also includes a positioning plate 50 installed at one end of the translation bracket 10. The positioning plate 50 and the support bracket 12 are arranged opposite to each other and are used to position one end of the tunneling host 70 to limit the initial placement position of the tunneling host 70.

[0046] It should be understood that this application is not limited to the precise structure described above and shown in the accompanying drawings, and various modifications and changes can be made without departing from its scope. This application is intended to cover any variations, uses, or adaptations of the present invention that follow the general principles of this application and include common knowledge or customary technical means in the art that are not disclosed in this invention.
