The counterforce structure and the fixed end of the push system are connected through a force transmission structure (for example, pull rod). Thus, the counterforce structure can provide a pushing force to one side of the fixed end to push the main machine and / or the pipe segment to be laid in the direction of the fixed end, so as to gradually punch the liaison channel between the two main tunnels of the starting end tunnel and the receiving end tunnel.

[0016] Advantages

[0017] The pushing system of the utility model comprises a fixed end and a pushing end. The fixed end is installed and fixed, and the pushing end is used for applying a pushing force to the direction of the fixed end. Thus, by applying the pushing force to the direction of the fixed end through the pushing end, the target object such as the main machine and the pipe segment to be laid can be pushed, so that the pushing system realizes pushing excavation. In addition, the pushing system of the utility model further comprises a fine adjustment mechanism. The reason why the fine adjustment mechanism is arranged in the utility model is that the pushing force applied by the pushing end usually needs to be realized by cooperation of multiple pushing driving units, and the construction environment of the pushing excavation is also complex and changeable, in addition to the gravity of the pushing end itself. Any one of the above factors can cause the pushing end to deviate or displace, so that the pushing end cannot be completely aligned with the target object of the pushing end. In this case, the problem of uneven force application of the pushing end and local compression is prone to occur, and the effect and efficiency of the pushing excavation are affected, and even the pushing system is damaged. Therefore, the fine adjustment mechanism is arranged in the utility model, and the fine adjustment mechanism is used for applying force to the pushing end to adjust the pose of the pushing end relative to the target object of the pushing end. Thus, the position and attitude of the pushing end can be slightly adjusted when necessary, so as to ensure that the pushing end and the target object of the pushing end can be more accurately aligned with each other, and the purposes of improving the excavation efficiency and effect and protecting the pushing system are achieved.

DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0027] The utility model provides a kind of push system, which is a commonly used equipment 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 channels (such as the communication passage of a subway). Taking the communication passage as an example, it needs to open the pre-supporting trolley during construction, install and fix the push system, and face the counterforce structure of the push system to the main tunnel segment on the opposite side of the starting direction. Further, the counterforce structure exerts force from the starting side to the receiving side, so that the push system can push the main machine and / or the segment to be laid towards the receiving side for construction.

[0028] It can be understood that, in addition to bypass channel construction, the push system also has many other application scenarios in tunnel construction. It can be used for horizontal pushing, as well as vertical or inclined pushing. In addition to subway construction, the push system also has wide application prospects in the fields of underground pipeline laying, municipal pipe gallery construction, mining and excavation, etc.

[0029] For the basic structure and working principle of the push system, please refer to the existing technologies disclosed in Chinese patents CN219910759U, CN219840653U, CN218780355U, etc. (also the applicant's prior application), which will not be repeated here.

[0030] The deficiency of the existing pushing system is that the pushing end is difficult to be completely aligned with the target object, and the relative position of the two is prone to deviation. Even a slight deviation in alignment can cause uneven force on the pushing end, local compression, and affect the effect and efficiency of the pushing excavation, and even damage the pushing system.

[0031] As shown in Figure 1 To solve the above technical problems, the utility model provides a pushing system, which comprises: a fixed end 100, the fixed end 100 is installed and fixed; a pushing end 200, the pushing end 200 is used to apply a pushing force to the direction of the fixed end 100; a fine adjustment mechanism, the fine adjustment mechanism is used to apply force to the pushing end 200 to adjust the pose of the pushing end 200 relative to the target object of the pushing end.

[0032] It can be understood that the fixed end 100 refers to the end that is relatively fixed in the entire pushing system. Among them, the fixed end 100 of the pushing system is usually a starting sleeve. The starting sleeve is a fixed structure at the starting end of excavation, which is used to provide initial guidance and sealing function for the main machine 500 of the excavation equipment. The installation mode of the starting sleeve is to be fixed on the inner wall of the tunnel on the starting side through pre-buried bolts or welding or concrete base, and the axis of the fixed end 100 needs to coincide with the tunnel axis as much as possible.

[0033] The function of the pushing end 200 is to push the main machine 500 and / or the pipe segment to be installed along the starting sleeve from the starting side to the receiving side. As shown in Figure 2 The pushing end 200 of the utility model comprises a cylinder 230 and a counterforce frame 240. The counterforce frame 240 can be a box or a support, and a plurality of dispersedly arranged cylinders 230 are installed and fixed on the counterforce frame 240. The cylinder 230 is connected with the hydraulic pump through the oil circuit, the hydraulic pump inputs hydraulic oil to the cylinder 230 through the control valve, under the pressure action of the hydraulic oil, the piston of the cylinder 230 moves in the cylinder barrel, thereby pushing the piston rod to output the pushing force to the target object main machine 500 and / or the pipe segment to be installed.

[0034] In order to ensure that the pushing end 200 can push the main machine 500 and / or the pipe segment to be installed to advance smoothly to the direction of the fixed end 100, the utility model can set the pushing end 200 to be connected with the fixed end 100. Specifically, the counterforce frame 240 of the pushing end 200 is connected with the fixed end 100.

[0035] Exemplarily, as shown in Figure 3 and Figure 4 The pushing end 200 and the fixed end 100 can be connected with each other through a force transmission member 600.

[0036] The force transmission member 600 is used to transmit the reaction force of the jacking end 200 to the fixed end 100, so that the jacking system forms a stable force system. One end of the force transmission member 600 is connected with the fixed end 100 through a fastener 800 such as a nut or a rivet, and the other end is also connected with the jacking end 200 in a similar manner or structure. The above connection relationship makes the force transmission member 600 similar to an arm that holds the fixed end 100, and the tension of the arm enables the jacking end 200 including the oil cylinder 230 and the reaction frame 240 to stably jacking. The utility model can use a supporting component or structure to support and fix the jacking end 200, and in the case that the equipment conditions permit, the force transmission member 600 can also be directly used to support the jacking end 200. As shown in Figure 3 and Figure 4 The fixed end 100 can be provided with a connecting member 700. The connecting member 700 is used to connect the force transmission member 600 with the fixed end 100, and at least part of the force transmission member 600 penetrates and inserts into the connecting member 700. The connecting member 700 can be welded or riveted with the fixed end 100.

[0037] In the utility model, the force transmission member 600 can be any one of a rigid force transmission member, a flexible force transmission member and a driving force transmission member, and can realize force transmission. Exemplarily, the rigid force transmission member can be a pull rod, and the pull rod can be a threaded steel pull rod. The flexible force transmission member can be a cable. The driving force transmission member can be an oil cylinder or an electric cylinder.

[0038] Exemplarily, as shown in Figure 3 and Figure 4 The force transmission member 600 can be a rigid force transmission member and include a first force transmission member 610 and a second force transmission member 620 which are separately arranged and connected in a detachable manner. The first force transmission member 610 and the second force transmission member 620 can be connected with each other through a connector. For example, the first force transmission member 610 and the second force transmission member 620 are respectively screwed with the connector. The force transmission member 600 is arranged as at least two separate and detachable parts, which can facilitate the lowering of the to-be-installed segment and avoid the force transmission member 600 from hindering the to-be-installed segment from entering between the jacking end 200 and the main machine 500.

[0039] It should be noted that the utility model can connect the jacking end 200 with the fixed end 100, which includes the direct connection of the two through the force transmission member 600 and the indirect connection of the two. For example, as shown in Figure 3 and Figure 4As shown, in the case that the fixed end 100 is the originating sleeve, the force transmitting member 600, such as a pull rod, has one end directly connected with the jacking end 200 and the other end directly connected with the originating sleeve. For example, in the case that the fixed end 100 is the originating sleeve, the originating sleeve is fixed on the tunnel segment that has been laid, and one end of the force transmitting member 600 can be directly connected with the jacking end 200, and the other end is not directly connected with the originating sleeve, but is connected with the tunnel segment that has been laid. Since the originating sleeve is also fixed on the tunnel segment that has been laid, the force transmitting member 600 and the fixed end 100 are indirectly connected and fixed through the tunnel segment that has been laid. For another example, the utility model can set other structures or components on the tunnel segment that has been laid, and the force transmitting member 600 is connected with the structures or components to realize indirect mutual connection and fixation with the fixed end 100. In the utility model, the jacking end 200 can also be not connected with the fixed end 100.

[0040] After explaining the working mode of the jacking end 200, those skilled in the art can understand that the jacking end 200 needs to be aligned with the jacking end target object as much as possible during work. In other words, the jacking end 200 needs to ensure that the horizontal central axis thereof coincides with the horizontal central axis of the jacking end target object as much as possible during work. However, the jacking force applied by the jacking end 200 usually needs to be realized by multiple oil cylinders 230 as jacking driving units in cooperation with each other. The construction environment of the jacking excavation is also complex and changeable, and the excavation demand can involve ups and downs or turning. In addition, the jacking end 200 has large weight and volume. Any one of the above factors will affect the jacking direction of the jacking end 200 and can cause the jacking end 200 to deviate or shift, thereby causing the jacking end 200 to not be completely aligned with the jacking end target object.

[0041] In this case, the jacking end 200 is prone to uneven force application and local compression, which affects the effect and efficiency of the jacking excavation and even damages the jacking system. Therefore, the utility model sets a fine adjustment mechanism. The fine adjustment mechanism is used to apply force to the jacking end 200 to adjust the pose of the jacking end 200 relative to the jacking end target object. Thus, the position and attitude of the jacking end 200 can be slightly adjusted when necessary to ensure that the jacking end 200 and the jacking end target object can be more accurately aligned with each other, thereby achieving the purposes of improving the excavation efficiency and effect and protecting the jacking system.

[0042] It can be understood that the fine adjustment mechanism adjusts the pose of the jacking end 200 by applying force, such as pushing force or pulling force or supporting force or pressure, to the jacking end 200. In order to realize the above force application effect, the fine adjustment mechanism needs to be in contact with the jacking end 200, and the fine adjustment mechanism also needs to be supported and fixed to ensure that the fine adjustment mechanism has a force application point during force application and can realize force transmission.

[0043] It can be understood that the fine adjustment mechanism can be a cylinder, an electric cylinder, an electric push rod, a pneumatic cylinder or a screw rod, which can output force by doing work. The fine adjustment mechanism preferably outputs force by doing work in an extension mode to adjust the magnitude of the force.

[0044] Exemplarily, the fine adjustment mechanism is arranged at the bottom of the pushing end 200. By applying a pulling force to the pushing end 200 through the fine adjustment mechanism, the central axis of the pushing end 200 can be slightly lowered. By applying a pushing force to the pushing end 200 through the fine adjustment mechanism, the central axis of the pushing end 200 can be slightly raised.

[0045] Exemplarily, the fine adjustment mechanism is arranged at the top of the pushing end 200. By applying a pulling force to the pushing end 200 through the fine adjustment mechanism, the central axis of the pushing end 200 can be slightly raised. By applying a pushing force to the pushing end 200 through the fine adjustment mechanism, the central axis of the pushing end 200 can be slightly lowered.

[0046] Exemplarily, the fine adjustment mechanism is arranged at the left and / or right side of the pushing end 200. By applying a pushing force to the pushing end 200 through the fine adjustment mechanism, the central axis of the pushing end 200 can be slightly shifted left or right.

[0047] Preferably, the number of fine adjustment mechanisms is two or more, and they are arranged at different positions to apply force to the pushing end 200 in at least two different positions or in at least two different directions to adjust the pose of the pushing end 200.

[0048] Preferably, the fine adjustment mechanisms are arranged in pairs and are arranged on opposite sides of the center line of the pushing end 200. For example, a pair of fine adjustment mechanisms can be arranged on the upper and lower sides of the pushing end 200, or on the left and right sides, or on the front and back sides. For example, a pair of fine adjustment mechanisms can be symmetrically arranged on the bottom surface of the pushing end 200 along the vertical center line of the pushing end 200. For example, a pair of fine adjustment mechanisms can be symmetrically arranged on the left and right side surfaces of the pushing end 200 along the horizontal center line of the pushing end 200. The fine adjustment mechanisms arranged in pairs can cooperate with each other to more accurately and flexibly adjust the pose of the pushing end 200.

[0049] Preferably, the fine adjustment mechanisms are used to apply force to the pushing end 200 in at least two different directions, respectively. For example, one group or one fine adjustment mechanism is arranged below the pushing end 200 and is used to adjust the pose of the pushing end 200 in the up-down direction, and another group or one fine adjustment mechanism is arranged to the side of the pushing end 200 and is used to adjust the pose of the pushing end 200 in the horizontal direction. Arranging the fine adjustment mechanisms to apply force to the pushing end 200 in at least two different directions respectively helps to quickly and accurately adjust the position of the pushing end 200 in a complex construction environment, so that the horizontal center line of the pushing end target object is kept consistent with the pushing end 200, and the pushing force of the pushing end 200 is applied vertically to the main machine 500.

[0050] In some embodiments of the utility model, the fine adjustment mechanism comprises: a first fine adjustment mechanism 310, the first fine adjustment mechanism 310 is used to force the pushing end 200 in the first direction, wherein the first direction is the left-right direction or the front-back direction or the up-down direction.

[0051] It can be understood that the pushing end 200 can be in different positions and postures under different working conditions. The left-right direction, the front-back direction and the up-down direction of the utility model refer to the direction based on the pushing end 200. The pushing direction of the pushing end 200 is the front direction, and the direction opposite to the pushing direction is the back direction. The first fine adjustment mechanism 310 forces the pushing end 200 in one of the left-right direction, the front-back direction or the up-down direction, which is the most commonly used and practical position and posture adjustment mode for the pushing end 200.

[0052] As shown in Figure 1 , taking the left-right direction as the first direction, two first fine adjustment mechanisms 310 are arranged on the left and right sides of the pushing end 200 and force the pushing end 200 horizontally relative to the ground. The left first fine adjustment mechanism 310 pushes the pushing end 200 to the right. The right first fine adjustment mechanism 310 pushes the pushing end 200 to the left.

[0053] Preferably, when the first direction is the left-right direction, the first fine adjustment mechanism 310 is arranged at the lower position of the pushing end 200. The lower position does not refer to the bottom surface of the pushing end 200, but refers to the position above the pushing end 200 relative to the lower position, such as Figure 1 the lower position of the left and right sides of the pushing end 200. Since the pushing end 200 is subjected to gravity, arranging the first fine adjustment mechanism 310 at the lower position of the pushing end 200 can achieve the position and posture adjustment of the pushing end 200 with smaller pushing force or pulling force.

[0054] In some embodiments of the utility model, the fine adjustment mechanism further comprises: a second fine adjustment mechanism 320, the second fine adjustment mechanism 320 is used to force the pushing end 200 in the second direction, wherein the second direction is perpendicular to the first direction.

[0055] For example, taking the left-right direction of the pushing end 200 as the first direction, the front-back direction or the up-down direction of the pushing end 200 can be the second direction. For example, taking the up-down direction of the pushing end 200 as the first direction, the front-back direction or the left-right direction of the pushing end 200 can be the second direction. The first fine adjustment mechanism 310 and the second fine adjustment mechanism 320 can realize the adjustment of the position and posture of the pushing end 200 in the Cartesian plane rectangular coordinate system.

[0056] In the partial embodiments of the utility model, the fine adjustment mechanism further comprises: a third fine adjustment mechanism 330, the third fine adjustment mechanism 330 is used to force the push end 200 along the third direction, wherein the third direction is perpendicular to the second direction and the first direction respectively. The first fine adjustment mechanism 310, the second fine adjustment mechanism 320 and the third fine adjustment mechanism 330 that cooperate with each other can realize the adjustment of the arbitrary pose of the push end 200 in the three-dimensional orthogonal coordinate system, and the implementation mode of the pose adjustment is simple, and the moving distance and the angle during adjustment are easy to control.

[0057] It can be understood that the up-down adjustment mechanism can also be arranged at the upper end or the lower end of the push end 200, and the front-rear adjustment mechanism can also be arranged at the front end or the rear end of the push end 200. Only the left-right adjustment mechanism needs to be arranged at the left and right opposite sides of the push end 200, so that the precise adjustment of the left-right deviation of the push end 200 can be realized. However, as shown in Figure 1 and Figure 5 Preferably, the first fine adjustment mechanism 310, the second fine adjustment mechanism 320 and the third fine adjustment mechanism 330 are arranged on the left and right sides of the push end 200 respectively.

[0058] Preferably, as shown in Figure 1 and Figure 5 Each pair of first fine adjustment mechanisms 310 is used to force the push end 200 left and right respectively. Each pair of second fine adjustment mechanisms 320 is used to force the push end 200 from front to back or from back to front respectively along the same direction. Each pair of third fine adjustment mechanisms 330 is used to force the push end 200 from bottom to top or from top to bottom respectively along the same direction.

[0059] Exemplarily, each fine adjustment mechanism is an oil cylinder. The first fine adjustment mechanism 310 adjusts the slight swing of the push end 200 left and right by applying a pushing force. The second fine adjustment mechanism 320 adjusts the slight rotation of the push end 200 along the longitudinal central axis by applying a pushing force. The third fine adjustment mechanism 330 adjusts the slight up-down movement of the push end 200 along the longitudinal direction by applying a pushing force. If the strokes or the extension amounts of the left and right fine adjustment mechanisms in each pair of fine adjustment mechanisms are different, the position and the attitude of the push end 200 will be different. The above mode can make the push end 200 realize the pose adjustment of multiple degrees of freedom, so that the push end target object can be accurately aligned in any working condition.

[0060] In the partial embodiments of the utility model, as shown in Figure 1 and Figure 6As shown, the fine adjustment mechanism includes a first fine adjustment mechanism 310 for applying force to the pushing end 200 in the left-right direction; the first fine adjustment mechanism 310 includes a first fixed end 311 and a first telescopic end 312 capable of telescoping relative to the first fixed end 311; the pushing end 200 is provided with a first support 210, either of the first fixed end 311 and the first telescopic end 312 is fixedly installed on the first support 210, and the other is used to apply force to the pushing end 200. Taking a hydraulic cylinder as an example, the first fixed end 311 is the cylinder barrel of the hydraulic cylinder, and the first telescopic end 312 is the piston assembly of the hydraulic cylinder. The first support 210 is a bracket which can be provided on the reaction frame 240 of the pushing end 200 by welding or integral molding. The first fixed end 311 can be clamped with the first support 210, so that the first support 210 can limit the movement of the first fixed end 311. The first telescopic end 312 can be connected with the reaction frame 240 or can only be in contact with the reaction frame 240. The first fine adjustment mechanism 310 can be installed on the surface of the reaction frame 240 or can be installed inside the reaction frame 240. The first fine adjustment mechanism 310 as a mechanism for realizing left-right fine adjustment can be directly installed and fixed on the pushing end 200, and does not need to use external structures as fulcrums to apply force to the pushing end 200.

[0061] In some embodiments of the present application, as shown in Figure 3 and Figure 4 As shown, the fine adjustment mechanism includes a second fine adjustment mechanism 320 for applying force to the pushing end 200 in the front-back direction; the second fine adjustment mechanism 320 includes a second fixed end 321 and a second telescopic end 322 capable of telescoping relative to the second fixed end 321; the pushing end 200 is provided with a second support 220, the second support 220 is at least two rib plates 221 arranged in the front-back direction on the side wall of the pushing end 200; the first fixed end 311 and the second telescopic end 322 are respectively fixedly installed on different rib plates 221. The at least two rib plates 221 can be provided on the reaction frame 240 of the pushing end 200 by welding or integral molding. At least one rib plate 221 of the at least two rib plates 221 is used to limit the movement of the second fixed end 321, and at least one rib plate 221 of the at least two rib plates 221 is used as a force point of the first telescopic end 312. The second fine adjustment mechanism 320 as a mechanism for realizing front-back rotation fine adjustment can be directly installed and fixed on the pushing end 200, and does not need to use external structures as fulcrums to apply force to the pushing end 200.

[0062] If the external structure is used as the fulcrum of the two fine adjustment mechanisms and the supporting fixed element, the structure of the pushing system will become more complex. If the first fine adjustment mechanism 310 and the second fine adjustment mechanism 320 adopt the above structure and installation and fixing mode, the two can respectively apply force to the pushing end 200 when pushing, without the need of external structure as the fulcrum, which is simple in structure and convenient to install.

[0063] In some embodiments of the utility model, as shown in Figure 2 The fine adjustment mechanism includes a third fine adjustment mechanism 330 for applying force to the pushing end 200 in the up-down direction; the third fine adjustment mechanism 330 includes a third fixed end 331 and a third telescopic end 332 capable of extending and retracting relative to the third fixed end 331; the pushing system further includes a pair of columns 400 arranged on the left and right sides of the pushing end 200, and any one of the third fixed end 331 and the third telescopic end 332 is installed and fixed on the column 400, and the other is used to apply force to the pushing end 200.

[0064] It can be understood that the third fine adjustment mechanism 330 is used to apply force to the pushing end 200 in the up-down direction, and since the influence of the self-weight of the pushing end 200, the column 400 is used to support the third fine adjustment mechanism 330, which is helpful to the stable force of the third fine adjustment mechanism 330 to adjust the slight movement of the pushing end 200 in the up-down direction. 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.
