DETAILED DESCRIPTION

[0024] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application.

[0025] The present application provides a kind of push tunneling equipment, which is the equipment commonly used in tunnel construction. For example, when tunnel construction is carried out by mechanical method, it is often necessary to involve the excavation and laying of bypass channel (such as the communication passage of subway). Taking the communication passage as an example, it needs to open the pre-supporting trolley during construction, install and fix the push tunneling equipment, and face the main tunnel segment on the opposite side of the starting direction of the counter-force structure of the push tunneling equipment. Further, the counter-force structure is launched by the starting side to the receiving side, so that the push tunneling equipment can push the main machine and / or the segment to be laid to the receiving side to carry out construction.

[0026] For the basic structure and working principle of the push tunneling equipment, please refer to the prior art disclosed in Chinese patents CN219910759U, CN219840653U and CN218780355U (also the prior application of the applicant), which will not be repeated here.

[0027] It can be understood that in addition to bypass channel construction, the push tunneling equipment also has many other application scenarios in tunnel construction. It can be used for horizontal pushing, and also can be used for vertical or inclined pushing. In addition to subway construction, the push tunneling equipment also has wide application prospects in the fields of underground pipeline laying, municipal pipe gallery construction and mining excavation.

[0028] The push tunneling equipment needs to provide a pushing force through the counter-force structure to push the target object forward. In tunnel construction, the counter-force structure is generally a counter-force frame and a counter-force oil cylinder installed on the counter-force frame, and the target object is generally the main machine of the tunneling machine or the segment to be laid.

[0029] The pushing method of the counter-force structure in the prior art can be seen in the prior art of CN218093039U, which installs a hydraulic cylinder (equivalent to a power unit) on the counter-force frame and connects the counter-force frame and the starting sleeve with a pull rod. Thus, the pushing force provided by the hydraulic cylinder makes the pull rod be tensioned. The tension makes the pull rod act like an arm that grips the starting sleeve, and the tension of the arm makes the counter-force structure be able to push the tunneling stably.

[0030] Through the analysis of the prior art, it can be known that the power unit and the counterforce frame are generally bulky in volume and heavy in weight, and thus the tension provided by the counterforce structure to the pull rod can cause uneven force on the pull rod and the problems of linear force or point force, which can easily cause the pull rod to be damaged and deformed.

[0031] In order to solve the above problems, the utility model provides a jacking tunneling equipment, the jacking tunneling equipment includes: jacking end 200, jacking end 200 includes power unit 210, power unit 210 is used to supply power to make jacking end 200 jacks to the direction of fixed end 100, force transmission structure 300, force transmission structure 300 has opposite first end 300a and second end 300b, wherein, first end 300a is connected with fixed end 100, and the combined spherical washer 400 is arranged between the two, and / or, second end 300b is connected with jacking end 200, and the combined spherical washer 400 is arranged between the two.

[0032] Specifically, the role of jacking end 200 is to jacks the main machine 700 and / or the pipe piece to be installed along the starting sleeve 600 from the starting side to the receiving side. The jacking end 200 of the utility model includes a power unit 210, which is installed on a counterforce frame 220. The power unit 210 is specifically a hydraulic oil cylinder, which is connected with a hydraulic pump through an oil circuit. The hydraulic pump inputs hydraulic oil to the hydraulic oil cylinder through a control valve. Under the pressure action of the hydraulic oil, the piston of the hydraulic oil cylinder moves in the cylinder barrel, thereby pushing the piston rod to output jacking force to the target main machine 700 and / or the pipe piece to be installed.

[0033] The starting sleeve 600 is a fixed structure at the starting end of tunneling, which is used to provide initial guiding and sealing functions for the main machine 700 of the tunneling equipment. The installation mode of the starting sleeve 600 is to be fixed on the inner wall of the tunnel at the starting side through pre-buried bolts or welding or concrete base, and the axis thereof coincides with the axis of the tunnel.

[0034] In the utility model, the second end 300b of the force transmission structure 300 is connected with the jacking end 200, and the first end 300a is connected with the fixed end 100. Among them, the fixed end 100 can be the starting sleeve 600, or the main tunnel pipe piece at the starting side, or the main tunnel pipe piece at the receiving side. The role of the force transmission structure 300 is to transmit the counterforce of the jacking end 200 to the fixed end 100, so that the jacking tunneling equipment forms a stable force system. The above connection relationship makes the role of the force transmission structure 300 similar to the arm that grips the fixed end 100, and the tension of the arm enables the jacking end 200 including the power unit 210 to stably jack the tunneling. The utility model can adopt a supporting component or structure to support and fix the jacking end 200, and under the condition that the equipment condition permits, the force transmission structure 300 can also be directly selected to support the jacking end 200.

[0035] AsFigure 1 As shown in the first embodiment of the utility model, the first end 300a of the force transmission structure 300 can be mounted and fixed to the tunnel segment, that is, the tunnel segment as the fixed end 100. Figure 2 As shown in the second embodiment of the utility model, the first end 300a of the force transmission structure 300 can be mounted and fixed to the anchoring platform 120 of the tunnel segment, that is, the anchoring platform 120 of the tunnel segment as the fixed end 100. Figure 3 As shown in the third embodiment of the utility model, the first end 300a of the force transmission structure 300 can be mounted and fixed to the outer ring sleeve set outside the originating sleeve 600, that is, the outer ring sleeve as the fixed end 100. The outer ring sleeve is mounted and fixed to the tunnel segment 800 by anchoring or welding. In the fourth embodiment of the utility model, the first end 300a of the force transmission structure 300 can be mounted and fixed to the originating sleeve 600. The fourth embodiment of the utility model is not shown in the figure, and those skilled in the art can understand that the shape and position of the originating sleeve 600 are the same as those of the first to third embodiments of the utility model. Figure 3 As shown in the case where the force transmission structure 300 is mounted on the originating sleeve 600, the outer ring sleeve in the above-mentioned Figure 3 can be removed, and the first end 300a of the force transmission structure 300 can be directly mounted and fixed to the originating sleeve 600 by the corresponding mounting mode. In the fifth embodiment of the utility model, the first end 300a of the force transmission structure 300 can be mounted and fixed to the receiving sleeve. The fifth embodiment of the utility model is not shown in the figure, and those skilled in the art can understand that the connection and fixing mode between the force transmission structure 300 and the receiving sleeve can be the same as that of the first to third embodiments of the utility model. In the sixth embodiment of the utility model, the first end 300a of the force transmission structure 300 can be mounted and fixed to the outer ring sleeve set outside the receiving sleeve. It should be noted that if the end of the force transmission structure 300 away from the jacking end 200 is mounted and fixed to the receiving side, the force transmission structure 300 needs to pass through the main tunnel segment to realize the installation, which requires pre-drilling and relatively complex construction process and installation structure. Therefore, the first end 300a of the force transmission structure 300 is preferably mounted and fixed to the originating side in the utility model, which not only simplifies the construction process, but also makes the structure more compact, and the construction of the originating end is not affected by the receiving end, that is, even if the receiving end does not have construction conditions, the originating end can still be normally constructed.

[0036] As shown in the first embodiment of the utility model, Figures 1 to 3 Compared with directly mounting and fixing the first end 300a of the force transmission structure 300 to the originating sleeve 600, the first end 300a of the force transmission structure 300 is preferably mounted and fixed to the tunnel segment or the outer ring sleeve of the originating side in the utility model, so as to avoid the problems of deviation and deformation of the originating sleeve 600 due to strong pulling force.

[0037] Exemplarily, asFigure 1 As shown, the anchor block 110 is installed on the tunnel segment of the fixed end 100, and the force transmission structure 300 is connected with the tunnel segment through the anchor block 110. The anchor block 110 can be connected with the embedded steel plate or steel bar in the tunnel segment through an anchor bolt.

[0038] As shown, the force transmission structure 300 can be installed and fixed on the anchor platform 120 of the tunnel segment of the originating side. Specifically, the tunnel segment has an inner concave arc surface, and the anchor platform 120 is arranged on the inner concave arc surface, and the force transmission structure 300 is connected with the anchor platform 120. Figure 2 It can be understood that the anchor platform 120 is a structure artificially applied on the inner concave arc surface of the tunnel segment, which can be a steel structure, a concrete structure, or a reinforced concrete blended structure. The anchor platform 120 not only facilitates the installation of the force transmission structure 300, but also facilitates the fixation of other structures such as the originating sleeve 600.

[0039] The installation and fixation of the force transmission structure 300 on the tunnel segment of the originating side not only avoids the influence of the force transmission structure 300 on the originating sleeve 600 when subjected to tension. Moreover, the tunnel segment usually adopts a steel structure or a concrete structure or a reinforced concrete blended structure, and the material properties facilitate the installation and fixation of the force transmission structure 300, and reliable installation and fixation of the force transmission structure 300 can be achieved only through the anchor block 110 and / or the anchor platform 120.

[0040] As shown, the outer sleeve is specially used to realize the installation and fixation of the force transmission structure 300. In order to ensure uniform stress, the outer sleeve can be sleeved on the outer periphery of the originating sleeve 100, so that multiple force transmission structures 300 can be uniformly arranged along the circumference of the originating sleeve 600. Preferably, in order to avoid transmitting the tension from the force transmission structure 300 to the originating sleeve 600, there is no connection relationship between the outer sleeve and the originating sleeve 100.

[0041] Figure 3 Compared with the first and second embodiments of the utility model, by setting the outer sleeve, the length of the force transmission structure 300 can be shortened, the torque can be shortened, thereby protecting the force transmission structure 300, and reducing the stress of the force transmission structure 300 away from the jacking end 200 side.

[0042] It can be understood that in the utility model, the force transmission structure 300 is specifically a rigid force transmission structure, and exemplarily, the force transmission structure 300 can be a tension rod, and the tension rod can be specifically a threaded steel tension rod.

[0043] It can be understood that in the utility model, the force transmission structure 300 is specifically a rigid force transmission structure, and exemplarily, the force transmission structure 300 can be a tension rod, and the tension rod can be specifically a threaded steel tension rod.

[0044] ​When the pushing end 200 is in the non-working state, the force transmission structure 300 is in the relaxed state and is not tensioned. When the pushing end 200 is in the working state, the force transmission structure 300 is subjected to tension and is tensioned due to the action of the power unit 210.

[0045] It can be understood that the combined spherical surface gasket 400 can be arranged at the first end 300a or the second end 300b of the force transmission structure 300, or the combined spherical surface gaskets 400 with the same structure can be arranged at the first end 300a and the second end 300b respectively. In the case that the combined spherical surface gaskets 400 are arranged at the opposite ends of the force transmission structure 300, the force transmission structure 300 is more uniformly stressed.

[0046] The self-weight of the pushing end 200 and the pushing force of the power unit 210 can cause the force transmission structure 300 to be unevenly stressed. In the case that the force transmission structure 300 is unevenly stressed, the combined spherical surface gasket 400 can be self-adaptively adjusted to adjust the stress position of the force transmission structure 300, so as to ensure that the force transmission structure 300 is uniformly stressed.

[0047] It can be understood that the combined spherical surface gasket 400 of the utility model is preferably made of a rigid material such as metal, so as to ensure that the force transmission structure 300 is stably connected and cannot shake.

[0048] As shown in Figure 5 The combined spherical surface gasket 400 includes the concave gasket 400a and the convex gasket 400b arranged in two parts, and the concave gasket 400a and the convex gasket 400b are in concave-convex cooperation. In the relaxed state of the force transmission member 310, the concave gasket 400a and the convex gasket 400b can be in contact or not in contact. In the tensioned state of the force transmission member 310, the concave gasket 400a and the convex gasket 400b are in close contact, so as to ensure the transmission of force.

[0049] Preferably, the convex diameter of the convex gasket 400b is greater than or equal to the concave diameter of the concave gasket 400a, so as to ensure that the convex gasket 400b can rotate above the concave gasket 400a and always keep the surface of the concave gasket 400a and the surface of the convex gasket 400b fully fitted.

[0050] In order to ensure that the force transmission structure 300 works stably and uniformly transmits force, the utility model applies the combined spherical surface gasket 400 to the pushing and tunneling equipment, and the following designs and improvements are made on the structure of the force transmission structure 300 and the position cooperation relationship between the force transmission structure 300 and the combined spherical surface gasket 400.

[0051] The force transmission structure 300 comprises: a force transmission member 310 arranged between the jacking end 200 and the fixed end 100; and a connecting member 320 used for connecting the force transmission member 310 with the fixed end 100 or the jacking end 200; wherein one side of the combined spherical washer 400 faces the connecting member 320, and the other side faces the fixed end 100 or the jacking end 200.

[0052] The force transmission member 310 is specifically a long rod made of threaded steel or alloy material. The connecting member 320 is specifically a fastener, which can be threadedly connected with the force transmission member 310, or can be riveted or welded. It can be understood that the connecting member 320 comprises a first connecting member 321 and a second connecting member 322. Figure 4 and Figure 5 As shown, the first connecting member 321 is arranged at the fixed end 100, and is used for connecting the first end 300a of the force transmission member 310 with the fixed end 100. The second connecting member 322 is arranged at the jacking end 200, and is used for connecting the second end 300b of the force transmission member 310 with the jacking end 200.

[0053] As shown, the first connecting member 321 is arranged at the fixed end 100, and is used for connecting the first end 300a of the force transmission member 310 with the fixed end 100. The second connecting member 322 is arranged at the jacking end 200, and is used for connecting the second end 300b of the force transmission member 310 with the jacking end 200. Figure 4 and Figure 5 As shown, the combined spherical washer 400 comprises a first combined spherical washer 410 arranged at the first end 300a of the force transmission structure 300, and a second combined spherical washer 420 arranged at the second end 300b of the force transmission structure 300.

[0054] In order to facilitate the installation of the force transmission structure 300, the jacking and tunneling equipment further comprises: a mounting member 500 arranged above the fixed end 100 or the jacking end 200; wherein the mounting member 500 is used for relatively mounting and fixing the force transmission member 310 with the fixed end 100 or the jacking end 200, and the connecting member 320 is used for limiting the force transmission member 310 from being separated from the mounting member 500; and the combined spherical washer 400 is sleeved on the force transmission member 310, and is located between the connecting member 320 and the mounting member 500.

[0055] In other words, the mounting member 500 can be arranged at the fixed end 100, or can be arranged at the jacking end 200. In the first embodiment of the utility model, the force transmission structure 300 is mounted on the pipe segment at the originating side through the mounting member 500. Similarly, in the second and third embodiments of the utility model, the force transmission structure 300 is respectively mounted on the anchoring platform 120 on the pipe segment, and on the outer ring sleeve outside the originating sleeve 600 through the mounting member 500.

[0056] The mounting member 500 is preferably made of metal, and is provided with a through hole, and the force transmission member 310 penetrates through the through hole to be relatively fixed with the mounting member 500. For example, the connecting member 320 in the form of a nut is screwed with the force transmission member 310 to avoid the force transmission member 310 from being separated from the through hole of the mounting member 500.

[0057] Preferably, in order to transmit force evenly, the force transmission structure 300 is arranged in multiple and / or groups. For example, the force transmission structure 300 can be arranged in a group of one, and multiple force transmission structures 300 are arranged around the circumference of the originating sleeve 600. For another example, the force transmission structure 300 can be arranged in a group of 2-6, and 2-6 groups of force transmission structures 300 are arranged around the circumference of the originating sleeve 600.

[0058] As shown in the drawings, in the case where the force transmission structure 300 is arranged in multiple and / or groups, at least two of the force transmission structures 300 share one mounting member 500. For example, the mounting member 500 is provided with multiple through holes, and each of the multiple force transmission structures 300 in the same group is arranged in the mounting member 500 through a through hole. Figures 1 to 5

[0059] The structure that at least two of the force transmission structures 300 share one mounting member 500 can facilitate the mounting and fixing of the force transmission structure 300, simplify the construction process, and improve the construction efficiency.

[0060] For example, the mounting member 500 includes a first mounting member 510 arranged on the fixed end 100, and the first connecting member 321 and the first combined spherical washer 410 are located on the side of the first mounting member 510 away from the pushing end 200. Thus, when the pushing end 200 pushes the main machine 700, the force transmission member 310 is tensioned by the pulling force. The first connecting member 321 can prevent the force transmission member 310 from being pulled out of the first mounting member 510, and the first combined spherical washer 410 can ensure that the first connecting member 321 and the first mounting member 510 are always in surface stress.

[0061] For example, the connecting member 320 includes a second connecting member 322 arranged on the pushing end 200, and the combined spherical washer 400 includes a second combined spherical washer 420 arranged on the second end 300b. The second connecting member 322 and the second combined spherical washer 420 are located on the side of the pushing end 200 away from the fixed end 100. Thus, when the pushing end 200 pushes the main machine 700, the force transmission member 310 is tensioned by the pulling force. The second connecting member 322 can prevent the force transmission member 310 from being pulled out of the pushing end 200, and the second combined spherical washer 420 can ensure that the second connecting member 322 and the pushing end 200 are always in surface stress.

[0062] Preferably, the pushing end 200 further includes a counterforce frame 220, and the power unit 210 is arranged on the counterforce frame 220. The force transmission member 310 is connected to the pushing end 200 by being inserted into the counterforce frame 220. The second connecting member 322 is used to limit the separation of the force transmission member 310 and the counterforce frame 220. One side of the second combined spherical washer 420 faces the second connecting member 322, and the other side faces the counterforce frame 220.

[0064] As shown in Figure 3 and Figure 4 As shown in

[0065] In the utility model, the force transmission structure 300 can be an integral structure, or can comprise at least two parts arranged in a split manner. As shown in Figure 5 The force transmission structure 300 comprises a first force transmission member 311 and a second force transmission member 312 connected in a detachable manner. The first force transmission member 311 and the second force transmission member 312 can be connected to each other through a connector 313. For example, the first force transmission member 311 and the second force transmission member 312 are respectively threadedly connected to the connector 313. Arranging the force transmission structure 300 as at least two parts arranged in a split manner and detachable can facilitate the lowering of the pipe segment to be installed, and avoid the force transmission structure 300 from hindering the pipe segment to be installed from entering between the jacking end 200 and the main machine 700. Finally, it should be noted that: the above examples are only used to illustrate the technical solutions of the utility model, and not to limit them; although the utility model has been described in detail with reference to the foregoing examples, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing examples, or make equivalent replacement for part of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the utility model.
