Description

Technical Field

[0001] This utility model relates to the field of tunnel construction technology, and more specifically, to a reverse-pull jacking device. Background Technology

[0002] Counter-pushing equipment is commonly used in tunnel construction. For example, tunnel construction often involves the excavation of side passages to achieve interconnection of underground space networks. Construction scenarios such as subway connecting passages, highway connecting passages, subway entrances and ventilation shafts, municipal utility tunnel maintenance shafts, intermediate ventilation shafts of long tunnels, and waterworks tunnel connecting lines all involve the excavation of side passages that connect one or two main tunnels.

[0003] Taking a subway connecting tunnel as an example, a reverse-pull jacking device can be used for tunneling during construction. One end of the reverse-pull jacking device is fixed (fixed end), and the other end (jacking end) is equipped with a hydraulic cylinder. The jacking end and the fixed end are connected by a force transmission structure (such as a tie rod). Thus, the jacking end can provide jacking force to one side of the fixed end to push the main unit and / or the tunnel segments to be laid towards the fixed end, thereby gradually opening up the connecting tunnel between the two main tunnels, the starting tunnel and the receiving tunnel.

[0004] The existing technology of reverse-pull jacking equipment has the following shortcomings: the jacking end of the equipment typically includes a hydraulic cylinder and a hydraulic cylinder support structure for mounting the cylinder. The hydraulic cylinder support structure not only supports the cylinder but also connects to the force transmission structure to withstand the counter-tension force from the force transmission structure. This results in the hydraulic cylinder support structure being continuously stressed and prone to damage. Improving the structural rigidity and service life of the hydraulic cylinder support structure requires increasing its manufacturing cost. Utility Model Content

[0008] In the above technical solution, the jacking end also includes: a support unit, which is used to support the power unit; wherein, the support unit is a box or frame.

[0009] In the above technical solutions, the force transmission component penetrates through the support unit; or the force transmission component avoids the support unit; or the power unit includes multiple hydraulic cylinders; or the support unit includes a first support unit and a second support unit that are separately configured.

[0010] In the above technical solution, a first connecting member is provided on the reaction frame, a force transmission member passes through the first connecting member and is connected to the first connecting member through a first fastener, and the first connecting member and the first fastener are located on the side of the reaction frame facing the fixed end.

[0015] Beneficial effects

[0016] The present invention relates to a reverse-pull jacking device comprising a fixed end and a jacking end. The fixed end is fixedly installed, and the jacking end applies a jacking force in the direction of the fixed end. Thus, by applying a jacking force from the jacking end to the fixed end, the target object, such as the main machine or the tunnel lining segments to be laid, can be jacked, enabling the jacking device to perform jacking tunneling. Furthermore, the present invention also includes a reverse-pull mechanism, which comprises a reaction frame and a force transmission component. The reaction frame is located on the side of the jacking end facing away from the fixed end and contacts the jacking end. One end of the force transmission component is fixedly installed, and the other end is connected to the reaction frame. Therefore, when the jacking end pushes forward, the reaction frame, which is separately located from the jacking end, bears the reverse pull force from the force transmission component, thereby reducing the stress on the jacking end, lowering the requirements for the structural rigidity of the jacking end, and reducing the manufacturing cost of the jacking end.

Detailed Implementation

[0025] 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.

[0026] This invention provides a reverse-pull jacking device, which is commonly used in tunnel construction. For example, in mechanical tunnel construction, it is often necessary to excavate and lay side passages (such as subway connecting passages). Taking a connecting passage as an example, during its construction, the pre-support trolley needs to be opened during the initial stage, the reverse-pull jacking device needs to be installed and fixed, and the reaction structure of the reverse-pull jacking device needs to face the main tunnel segment on the opposite side of the starting direction. Then, through the reaction structure, force is exerted from the starting side to the receiving side to jack, thereby the reverse-pull jacking device can push the main tunnel segment and / or the segment to be laid towards the receiving side for construction.

[0027] It's understandable that, besides bypass tunnel construction, reverse-pull jacking equipment has many other applications in tunnel construction. It can be used for lateral jacking, as well as longitudinal or inclined jacking. In addition to subway construction, reverse-pull jacking equipment has broad application prospects in underground pipeline laying, municipal utility tunnel construction, mining excavation, and other engineering fields.

[0028] For the basic structure and working principle of the reverse-pull jacking device, please refer to the prior art disclosed in Chinese patents with publication numbers CN219910759U, CN219840653U, and CN218780355U (which are also the applicant's prior applications), and the applicant will not elaborate further here.

[0029] Counter-pushing equipment requires the jacking force provided by the reaction structure to push the target object forward. In tunnel construction, the reaction structure is generally a reaction frame and reaction cylinders installed on the reaction frame, and the target object is generally the main unit of the tunnel boring machine or the tunnel lining segments to be laid.

[0030] The shortcomings of existing technology are: the jacking end of a counter-pull jacking device typically includes a hydraulic cylinder and a hydraulic cylinder support structure for mounting the cylinder. The hydraulic cylinder support structure not only supports the cylinder but also connects to the force transmission structure to withstand the counter-tension force from the force transmission structure. This results in the hydraulic cylinder support structure being continuously stressed and prone to damage. Improving the structural rigidity and service life of the hydraulic cylinder support structure requires increasing its manufacturing cost.

[0031] like Figure 1 As shown, in order to solve the above-mentioned technical problems, this utility model provides a reverse-pull jacking device, which includes: a fixed end 100, which is installed and fixed; a jacking end 200, which is used to apply a jacking force in the direction of the fixed end 100; and a reverse-pull mechanism, which includes a reaction frame 310 and a force transmission component 320. The reaction frame 310 is located on the side of the jacking end 200 away from the fixed end 100 and is in contact with the jacking end 200. One end of the force transmission component 320 is installed and fixed, and the other end is connected to the reaction frame 310.

[0032] It can be understood that the fixed end 100 refers to the relatively fixed end in the entire reverse-pull jacking equipment. The fixed end 100 is typically the launching sleeve. As a fixed structure at the starting end of tunneling, the launching sleeve provides initial guidance and sealing for the main unit of the tunneling equipment. The launching sleeve is installed by pre-embedded bolts, welding, or a concrete base, fixing it to the inner wall of the tunnel on the launching side. The axis of the fixed end 100 needs to be as coincident as possible with the tunnel axis. The jacking end 200's function is to push the main unit and / or the segments to be installed along the launching sleeve from the launching side to the receiving side.

[0033] In the prior art, the jacking end 200 typically includes a hydraulic cylinder and a hydraulic cylinder support structure. For example, the force transmission structure of the tie rod connects the hydraulic cylinder support structure and the fixed end. Thus, during hydraulic cylinder jacking, the hydraulic cylinder support structure bears the counter-tension force from the force transmission structure, making it act like an arm holding the fixed end 100, ensuring that the jacking end 200 can smoothly push the main unit and / or the segment to be installed towards the fixed end 100. Therefore, the hydraulic cylinder support structure in the prior art is generally referred to as a "reaction frame".

[0034] Because the hydraulic cylinder support structure needs to withstand continuous tensile force during cylinder operation, its manufacturing cost has always been high to ensure its structural rigidity meets usage requirements. Although called a "reaction frame," existing hydraulic cylinder support structures generally cannot be made into a bracket shape; instead, they require welding stainless steel plates or alloys into a box-frame structure. Besides the high material cost, the hydraulic cylinder support structure is also heavy. This results in greater power required for cylinder pushing and makes it relatively difficult to control. The high weight of the hydraulic cylinder support structure also makes the pushing end prone to displacement, making it difficult to perfectly align with the fixed end.

[0035] Therefore, to reduce the manufacturing cost and weight of the jacking end 200, primarily the related structures supporting the hydraulic cylinder within it, this invention specifically separates the fixed end 100 and the reaction frame 310. One end of the force transmission component 320 is fixedly mounted; for example, this end can be connected to the fixed end 100. The other end is not connected to the jacking end 200, but rather to the reaction frame 310 located behind the jacking end 200. Thus, the jacking end 200 is only used for jacking and no longer bears the counter-tension from the force transmission component 320. It will not be easily damaged due to continuous stress, and there is no need for high material costs. Furthermore, since the structural rigidity requirements of the jacking end 200 are reduced, it is no longer necessary to manufacture the jacking end 200 as a box-frame structure. Lightweight structures, such as brackets, can be used to support the power components that achieve the jacking, thereby reducing the weight of the jacking end 200, avoiding or reducing the possibility of the jacking end 200 shifting or moving during operation, reducing the difficulty of controlling the power components, improving the efficiency and effect of tunneling, and protecting the reverse jacking equipment.

[0036] Preferably, the side of the reaction frame 310 facing away from the pushing end 200 is an arc-shaped panel. The arc-shaped panel can fit against the inner wall of the tunnel, making it easier for the reaction frame 310 to abut against the inner wall of the tunnel, so that the inner wall of the tunnel can provide support for the reaction frame 310.

[0037] like Figure 1As shown, in the reverse-pull jacking device of this utility model, the jacking end 200 includes: a power unit 210, which is used to supply jacking force; wherein, the reaction frame 310 is in contact with the power unit 210, and the arrangement direction of the force transmission component 320 is consistent with the jacking direction of the power unit 210.

[0038] For example, the power unit 210 can be multiple hydraulic cylinders. The number of power units 210 can be one or multiple distributed. Taking a hydraulic cylinder as an example, the hydraulic cylinder is connected to a hydraulic pump through an oil circuit. The hydraulic pump inputs hydraulic oil into the hydraulic cylinder through a control valve. Under the pressure of the hydraulic oil, the piston of the hydraulic cylinder moves inside the cylinder barrel, thereby pushing the piston rod to output a thrust towards the target main body and / or the segment to be installed.

[0039] This invention configures the reaction frame 310 to abut against the power unit 210, so that the power unit 210 can transmit the jacking force to the reaction frame 310 during the jacking operation. Thus, after being subjected to force, the reaction frame 310 can interact with the force transmission component 320 connected to it, achieving mutual pulling. Setting the arrangement direction of the force transmission component 320 to be consistent with the jacking direction of the power unit 210 helps to ensure that the jacking force and the pulling force are opposite in direction and parallel to each other.

[0040] like Figure 1 As shown, in the reverse-pull jacking device of this utility model, the jacking end 200 further includes: a support unit 220, which is used to support the power unit 210; wherein, the support unit 220 is a box or frame.

[0041] The support unit 220 supports and fixes the power unit 210. Regardless of whether it is manufactured as a box or a frame, the support unit 220 in this utility model no longer bears the counter-tension force, because the requirement for its structural rigidity can be greatly reduced. Therefore, its structural design and material selection can be more flexible.

[0042] like Figure 2 and Figure 3 As shown, preferably, the support unit 220 includes a first support unit 221 and a second support unit 222, which are separately arranged. The first support unit 221 and the second support unit 222 are arranged horizontally to the left and right. The reason for separating the first support unit 221 and the second support unit 222 is that after separating the jacking end 200 and the reaction frame 310, the overall length of the main unit, the jacking end 200, and the reaction frame 310 is relatively long, making it inconvenient to transport the anti-pull jacking equipment into the tunnel. If the support unit 220 is divided into two or more parts, the two or more parts including the first support unit 221 and the second support unit 222 can be moved from both sides to both sides of the main unit during transportation, facilitating transportation within the tunnel.

[0043] The force transmission component 320 serves to create a stable force-bearing system for the jacking device. For example, one end of the force transmission component 320 can be connected to the fixed end 100 via fasteners such as nuts or rivets, and the other end can be connected to the reaction frame 310 using a similar fastener method or structure. This connection makes the force transmission component 320 function like an arm gripping the fixed end 100; the tension of the arm interacts with the jacking force of the jacking end 200, enabling the jacking end 200, including the power unit 210 and the support unit 220, to stably jack and excavate. This invention can employ a support component or structure to support and fix the reaction frame 310; if equipment conditions permit, 320 can also be used directly to support the reaction frame 310.

[0044] In this invention, the force transmission component 320 can be any of a rigid force transmission component, a flexible force transmission component, or a driving force transmission component, as long as it can transmit force. For example, the rigid force transmission component can be a tie rod, specifically a threaded steel tie rod. The flexible force transmission component can be a cable. The driving force transmission component can be a hydraulic cylinder or an electric cylinder.

[0045] like Figure 4 As shown, in this utility model, the force transmission component 320 includes a first force transmission component 321 and a second force transmission component 322 that are detachably connected. The first force transmission component 321 and the second force transmission component 322 can be connected to each other via a connector. For example, the first force transmission component 321 and the second force transmission component 322 can be threadedly connected to a connector. By configuring the force transmission component 320 as at least two separate and detachable parts, it facilitates the lowering of the tube segment to be installed and prevents the force transmission component 320 from obstructing the entry of the tube segment to be installed between the push end 200 and the main unit.

[0046] It should be noted that the force transmission component 320 and the fixed end 100 described in this utility model can be directly connected, indirectly connected, or not connected at all. For example, as Figure 3 and Figure 4As shown, when the fixed end 100 is a launching sleeve, for example, one end of the force transmission component 320 is directly connected to the reaction frame 310, and the other end is directly connected to the launching sleeve. Alternatively, when the fixed end 100 is a launching sleeve, the launching sleeve is fixed to the already laid tunnel segment. One end of the force transmission component 320 can be directly connected to the reaction frame 310, while the other end is not directly connected to the launching sleeve but is connected to the already laid tunnel segment. Since the launching sleeve is also fixed to the already laid tunnel segment, the force transmission component 320 and the fixed end 100 are indirectly connected and fixed through the already laid tunnel segment. Furthermore, this invention can install other structures or components on the already laid tunnel segment, and the force transmission component 320 can be indirectly connected and fixed to the fixed end 100 by connecting to these structures or components. For example, this invention can fit an outer sleeve around the starting sleeve, with the starting sleeve being the fixed end 100. The outer sleeve is not connected or in contact with the starting sleeve, and the outer sleeve is connected to the already laid tunnel segments. The force transmission component 320 can be installed and connected to the outer sleeve.

[0047] Regarding the connection method between the force transmission component 320 and the reaction frame 310, such as Figure 1 As shown, the force transmission component 320 can pass through the support unit 220 from the side where the fixed end 100 is located and be connected to the reaction frame 310. Figure 4 The diagram shows the situation after removing the support unit 220, as follows: Figure 4 As shown, the force transmission component 320 can also be positioned on the side where the fixed end 100 is located, bypassing the support unit 220, and connected to the reaction frame 310. The way the force transmission component 320 passes through the support unit 220 and connects to the reaction frame 310 makes both the reaction frame 310 and the force transmission component 320 more stable. Furthermore, the way the force transmission component 320 bypasses the support unit 220 and connects to the reaction frame 310 further avoids the impact of the counter-tension force on the support unit 220.

[0048] Regarding the installation and fixing method of the force transmission component 320 on the reaction frame 310, in one example, a first connecting member can be provided on the reaction frame 310. The force transmission component 320 passes through the first connecting member and is connected to the first connecting member by a first fastener. The first connecting member and the first fastener are located on the side of the reaction frame 310 facing the fixed end 100. The first connecting member is not shown in the figure, and its shape and structure are similar to... Figure 1 The second connector 110 is the same as the one in the middle, and the installation position is the same as that in the middle. Figure 1 The second connecting member 110 is symmetrical, and the force transmission member 320 can be installed and fixed to the first connecting member by fasteners such as nuts. The connection method between the force transmission member 320 and the first connecting member is the same as... Figure 1 The method of connecting the force transmission component 320 and the second connector 110 using the second fastener 330 is the same.

[0049] Regarding the installation and fixing method of the force transmission component 320 on the reaction frame 310, in another example, such as Figure 1 As shown, the force transmission component 320 passes through the reaction frame 310 and is connected to the reaction frame 310 via a third fastener 340, which is located on the side of the reaction frame 310 facing away from the fixed end 100. The connection and fixing method of the force transmission component 320 passing through the reaction frame 310 is more stable.

[0050] like Figures 2 to 4 As shown, a second connector 110 is provided on the fixed end 100. The force transmission member 320 passes through the second connector 110 and is connected to the second connector 110 by a second fastener 330, which is located on the side of the second connector 110 facing away from the reaction frame 310. Therefore, when the pushing end 200 pushes the main unit, the force transmission member 320 is tensioned by a pulling force. The second fastener 330 prevents the force transmission member 320 from coming off the second connector 110.

[0051] Another shortcoming of existing jacking equipment is that the jacking end is difficult to align perfectly with the fixed end, and their relative positions are prone to deviation. Even a small misalignment can lead to uneven force application and localized compression on the jacking end, affecting the effectiveness and efficiency of jacking tunneling, and even damaging the jacking equipment.

[0052] Preferably, to solve the above problems, the jacking device further includes a fine-tuning mechanism 400, which applies force to the jacking end 200 to adjust its position relative to the fixed end 100. Thus, the fine-tuning mechanism 400 can be used to make slight adjustments to the position and orientation of the jacking end 200 when necessary, ensuring that the jacking end 200 and the fixed end 100 are more precisely aligned, thereby improving tunneling efficiency and effectiveness and protecting the jacking device.

[0053] The fine-tuning mechanism 400 adjusts the position of the pushing end 200 by applying force to the pushing end 200, such as pushing, pulling, supporting, or compressing force. To achieve the above-mentioned force application effect, the fine-tuning mechanism needs to be in contact with the pushing end 200 and needs to be supported and fixed to ensure that the fine-tuning mechanism has a point of force application during the force application process and can realize the transmission of force.

[0054] The fine-tuning mechanism can be a hydraulic cylinder, an electric cylinder, an electric actuator, or a pneumatic cylinder, which outputs force by performing work. Preferably, the fine-tuning mechanism uses extension and retraction to achieve both the output and adjustment of the force.

[0055] For example, such as Figure 5 and Figure 6As shown, the fine-tuning mechanism 400 includes a first fine-tuning mechanism 410 for applying force to the pushing end 200 in the left-right direction, a second fine-tuning mechanism 420 for applying force to the pushing end 200 in the front-back direction, and a third fine-tuning mechanism 430 for applying force to the pushing end 200 in the up-down direction.

[0056] It is understood that the jacking end 200 may be in different positions and orientations under different working conditions. The left-right, front-back, and up-down directions mentioned in this utility model refer to directions based on the jacking end 200. Specifically, the jacking direction of the jacking end 200 is forward, and the direction opposite to the jacking direction is rearward.

[0057] The first fine-tuning mechanism 410, the second fine-tuning mechanism 420 and the third fine-tuning mechanism 430, which cooperate with each other, can adjust the position of the push end 200 in any position in the three-dimensional rectangular coordinate system. Moreover, the position adjustment is simple to implement and the movement distance and angle during adjustment are easy to control.

[0058] The first fine-tuning mechanism 410, the second fine-tuning mechanism 420, and the third fine-tuning mechanism 430 are hydraulic cylinders arranged in pairs on the left and right sides of the pushing end 200. The first fine-tuning mechanism 410, acting as a mechanism for left-right fine-tuning, can be directly mounted and fixed to the pushing end 200 without requiring an external structure as a fulcrum to apply force to the pushing end 200. The second fine-tuning mechanism 420, acting as a mechanism for front-back rotation fine-tuning, can also be directly mounted and fixed to the pushing end 200 without requiring an external structure as a fulcrum to apply force to the pushing end 200. The third fine-tuning mechanism 430 applies force to the pushing end 200 in the vertical direction. Due to the weight of the pushing end 200, a structure such as left and right columns is used to support the third fine-tuning mechanism 430, which helps to stabilize the force application of the third fine-tuning mechanism 430.

[0059] Since the reaction frame 310 is in contact with but not connected to the pushing end 200, the reaction frame 310 will not affect the posture adjustment of the pushing end 200 when the fine-tuning mechanism 400 adjusts the posture of the pushing end 200. 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; and these 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.
