Description

TECHNICAL FIELD

[0001] The utility model relates to the field of tunnel construction, concretely relates to a large-inclination angle inclined hole secondary lining construction traction type trolley. BACKGROUND

[0002] In railway and water conservancy tunnel construction, shield machines are usually used for tunneling, and secondary lining trolleys are used for lining support.

[0003] Currently, the secondary lining construction of the tunnel type anchorage of a suspension bridge is generally as follows: after the secondary lining construction of the inverted arch (bottom plate) is completed, full-steel pipe supports are set up on the surface of the inverted arch (bottom plate) as a formwork support system for pouring the secondary lining concrete; after the pouring of the secondary lining concrete is completed, one cycle of construction is finished.

[0004] When lining in a tunnel with a ramp, in order to adjust the lining elevation, the height difference between the front and rear ends of the trolley and the non-parallelism between the end face of the formwork and the end face of the portal will cause a large horizontal component force between the formwork and the portal, resulting in the misalignment of the support screw rod between the formwork and the portal, and causing damage to the screw rod and the oil cylinder. At the same time, since the formwork and the trolley are usually designed as a whole, the cumulative transverse deviation caused by the longitudinal movement of the main frame will affect the installation accuracy of the formwork. SUMMARY

[0035] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0036] The following is a detailed description of an embodiment of a traction trolley for secondary lining construction of a large-angle inclined tunnel according to the present invention in conjunction with the accompanying drawings.

[0037] like Figure 1 As shown, the present application provides a traction trolley for the construction of the second lining of a large-angle inclined tunnel, comprising an arch formwork 1, a support frame 2, a lateral adjustment component 3 and a vertical adjustment component 5. The arch formwork 1 is used to be attached to the inner wall of the tunnel through the support frame 2, and the position of the arch formwork 1 in the tunnel can be adjusted to a calibrated position through the lateral adjustment component 3 and the vertical adjustment component 5.

[0038] Specifically, the support frame 2 includes an upper support frame 21 and a portal frame 22. The upper support frame 21 is connected to the top of the arch formwork 1, and the portal frame 22 is located below the upper support frame 21 and inside the arch formwork 1; the lateral adjustment component 3 is connected to the upper support frame 21 and the portal frame 22, and is used to adjust the relative horizontal position of the arch formwork 1 in the tunnel; the vertical adjustment component 5 is connected to the portal frame 22, and is used to support the portal frame 22 to adjust the longitudinal inclination angle of the arch formwork 1.

[0039] During installation, after the gantry 22 moves to the set position in the tunnel through the track 8, the arch formwork 1 is installed, and the upper support frame 21 is connected to the top of the arch formwork 1. The relative position between the upper support frame 21 and the gantry 22 is adjusted by the lateral adjustment component 3 so that the center line of the arch formwork 1 coincides with the central axis of the tunnel. The gantry 22 is supported by the vertical adjustment component 5 to adjust the longitudinal inclination angle of the arch formwork 1 in the tunnel so that the arch formwork 1 fits the inner wall of the tunnel.

[0040] It can be understood that by adjusting the elevation of the arch formwork 1 through the lateral adjustment component 3 and the vertical adjustment component 5, the elevation of the gantry 22 can be adjusted, so that the arch formwork 1 can be accurately positioned in the inclined tunnel with a large inclination angle and installed on the inner wall of the tunnel through the support frame 2, which solves the problem of the height difference between the front and rear ends of the gantry and the non-parallelism between the end face of the formwork and the end face of the gantry. The support frame 2 is designed separately from the arch formwork 1, so that it can be adjusted at any time according to needs, and the accumulated lateral deviation caused by the longitudinal movement of the gantry 22 improves the installation accuracy of the formwork.

[0041] In some optional embodiments, the above-mentioned lateral adjustment component 3 includes a supporting member 31 and a transverse pushing member 32, one end of the supporting member 31 is connected to the above-mentioned upper support frame 21, and the other end is slidingly connected to the above-mentioned door frame 22; the fixed end of the transverse pushing member 32 is fixedly connected to the above-mentioned door frame 22, and its telescopic end is connected to the above-mentioned supporting member 31, and can be laterally telescopic.

[0042] In this example, there are two supporting members 31, which are arranged horizontally between the upper support frame 21 and the door frame 22. The supporting members 31 are I-shaped steel, and their top plates are fixedly connected to the upper support frame 21, and their bottom plates are slidably connected to the top of the door frame 22. There is one transverse pushing member 32, which is a telescopic cylinder, and its telescopic end is connected to the web of any I-shaped steel, so that when the telescopic cylinder is working, the arch template 1 is driven to move horizontally through the supporting members 31 and the upper support frame 21.

[0043] like Figure 2 As shown, since the arch formwork 1 includes a top formwork 11 and two side formworks 12 connected to both ends of the top formwork 11, the upper support frame 21 is connected to the top formwork 11, and the door frame 22 is connected to the side formworks 12. Therefore, the upper support frame 21 can be connected to the top formwork 11 first to form a circular arch formwork, and then the arch formwork can be adjusted horizontally using the horizontal adjustment assembly 3. After the arch formwork is adjusted into place, the side formworks 12 can be installed.

[0044] It should be noted that when installing the arch formwork, it should start from the middle and extend to both ends. This can reduce the cumulative error. After installing the first arch formwork in the middle and checking that the chord length and chord height meet the design standards, install the other arch formworks until all the top formworks 11 are installed. The arch formwork joints are ±1mm and the misalignment is 0.5mm. All bolts must be tightened in staggered directions, and spring washers and flat washers must be fully worn. After the arch formwork has been inspected and found to be correct, the side formwork 12 can be installed. The side formwork 12 is lifted upright next to the trolley at the predetermined position according to the number. The side formwork 12 is lifted to the installation position by the crane. The jack and crowbar are used for fine-tuning so that the central axis of the arch formwork hinged ear plate and the side formwork hinged ear plate coincide. Insert the pin 13 and lock it with a safety pin. Note that it cannot be installed on one side at a time. Both sides need to be installed symmetrically and then hoisted in sequence according to the number. After the side formwork 12 is installed, gap adjustment is required. The formwork flatness must not exceed 5mm, and the misalignment between panels must not exceed 2mm. If the misalignment between panels cannot be adjusted, it can be repaired with a grinder until it passes the inspection. After the arch formwork 1 has been fully inspected and accepted, to limit the movement between panels, rivets are installed between each steel plate for reinforcement.

[0045] Further, the upper support frame 21 comprises a horizontal rod 211 connected to both ends of the arc-shaped top formwork 11 and a plurality of support vertical rods 212 connected between the horizontal rod 211 and the arc-shaped top formwork 11, and the plurality of support vertical rods 212 are arranged at equal intervals.

[0046] In some optional embodiments, the vertical adjusting assembly 5 comprises at least one set of vertical pushing groups arranged at both ends of the portal frame 22 along the longitudinal direction.

[0047] It can be understood that, in order to make the arc-shaped formwork 1 completely fit the inner wall of the tunnel and reduce the height difference between the front end and the rear end of the portal frame, the top of the portal frame is parallel to the horizontal rod 211, and the elevations of the front end and the rear end of the portal frame are adjusted by the vertical adjusting assembly 5 to adapt to the angle of the large-inclination inclined hole.

[0048] Preferably, the vertical adjusting assembly 5 comprises two telescopic oil cylinders 51 arranged at intervals on the bottom longitudinal beams 221 of the portal frame 22.

[0049] That is, four telescopic oil cylinders 51 are arranged on the two bottom longitudinal beams 221 of the portal frame 22 respectively, and the connecting lines of the four telescopic oil cylinders 51 form a rectangle.

[0050] During adjustment, each telescopic oil cylinder 51 is correspondingly telescoped according to the requirement, so that the abutting force of each top holder 31 to the arch formwork is equal.

[0051] In this example, the fixed end of the telescopic oil cylinder 51 is fixed on the corbel 223 of the portal frame 22, the telescopic end abuts against the support column 224 on the running wheel, the bottom longitudinal beam 221 is provided with a sleeve 225, and the sleeve 225 is sleeved on the support column 224. When the telescopic end of the telescopic oil cylinder 51 abuts against the support column 224, the sleeve 225 moves up and down relative to the support column 224.

[0052] In some optional embodiments, as shown in Figure 3 and Figure 4 The trolley further comprises a positioning assembly 6, and the positioning assembly 6 comprises at least one adjustable screw rod 61 for connecting and fixing the portal frame 22 to the tunnel.

[0053] It can be understood that, since the portal frame 22 needs to keep the relative position fixed in the inclined inclined hole to accurately position the arc-shaped formwork 1, the portal frame 22 can be fixed by using the positioning assembly 6 after the portal frame 22 is moved to the set position in the tunnel by the track 8. In this example, the adjustable screw rod 61 can be arranged between the bottom longitudinal beam 221 of the portal frame 22 and the bottom surface of the tunnel, or between the running wheel and the track 8.

[0054] Of course, the fixation of the portal frame 22 can also be achieved by self-braking of the running wheel of the portal frame 22, and the portal frame 22 can be further stabilized by using the adjustable screw rod 61.

[0055] In some alternative embodiments, the gantry 22 and the side formwork 12 are connected by a connecting assembly 4, which comprises a plurality of horizontal lead screws 41, both ends of the horizontal lead screws 41 being connected to the gantry 22 and the side formwork 12 respectively.

[0056] It can be understood that, during the installation process, the side formwork 12 is first clamped or released by a single-layer horizontal jacking, a horizontal jacking cylinder being connected to one end of the gantry 22 and the other end of the side formwork 12, the horizontal jacking cylinder being extended or retracted, the side formwork 12 being turned outward around the hinge shaft until the bottom of the side formwork 12 is tightly attached to the low side wall of the tunnel. After the side formwork 12 is preliminarily adjusted in place by the horizontal jacking, and the spatial position of the side formwork 12 is checked and verified to be correct, the horizontal jacking is disassembled, and the horizontal lead screws 41 are used to finely adjust the spatial position of the side formwork 12 from bottom to top layer by layer until the side formwork 12 coincides with the theoretical position.

[0057] Preferably, a top-holding lead screw 121 is further arranged at the bottom end of the side formwork 12, one end of the top-holding lead screw 121 being connected to the side formwork 12 and the other end being connected to the bottom surface of the tunnel, which is used to hold the side formwork 12 and fix the side formwork 12 to the inner wall of the tunnel in cooperation with the horizontal lead screws 41.

[0058] In some alternative embodiments, the gantry 22 comprises a running mechanism 222, and the positioning assembly 6 further comprises a rail clamp 62 arranged on the running mechanism 222 for braking.

[0059] It can be understood that the running mechanism 222 is arranged on the two bottom longitudinal beams 221 of the gantry 22, one driving running wheel and one driven running wheel being arranged on each bottom longitudinal beam 221 respectively, and the rail clamp 62 is arranged on the driving running wheel and the driven running wheel, one end of the adjustable lead screw 61 being connected to the driving running wheel and the other end being connected to the bottom surface of the tunnel. It should be noted that the adjustable lead screw 61 is arranged at an angle with the horizontal plane of the tunnel, and the purpose is to provide horizontal and longitudinal components of force at the same time in the inclined inclined hole.

[0060] Further, as shown in FIG. 6, a horizontal counter-bracing rod is arranged on the completed bottom plate, and one end of the adjustable lead screw 61 away from the gantry 22 is connected to the horizontal counter-bracing rod, which is used to limit the horizontal position of the gantry 22. Figure 5

[0061] In some alternative embodiments, the trolley further comprises a traction device 7, the traction device 7 comprising a winch 71, a steel cable 72 and a steering support 73, the winch 71 being fixedly arranged and connected to the gantry 22 through the steel cable 72, and the steering support 73 being provided with at least one for adjusting the traction angle of the steel cable 72.

[0062] As shown in FIG. 7, the trolley is provided with a plurality of adjustable lead screws 61, the adjustable lead screws 61 being arranged on the gantry 22 and the side formwork 12 respectively, and the adjustable lead screws 61 being arranged at an angle with the horizontal plane of the tunnel. Figure 6 ​As shown, the portal 22 is moved to a set position in the tunnel by the traction device 7, the winch 71 is stopped to stop the relative position of the portal 22 in the tunnel, and the portal 22 is fixed by the positioning assembly 6.

[0063] In some optional embodiments, stress and inclination angle sensors are installed at key stress parts of the trolley, the safety and overall stability of the secondary lining trolley in the pouring state are monitored in real time, and are visually displayed on the central control integrated display platform. If stress or posture mutation occurs, the system will automatically issue a warning and send a short message to the manager's mobile phone.

[0064] Preferably, a fall arrest rope is further arranged at the front end of the portal 22, the fall arrest rope is a φ32, 6x37S+FC steel wire rope, after the steel wire rope is tightened by a guide chain, the other end of the steel wire rope is hung on an anchor base of the secondary lining base plate. The purpose is also to fix the relative position of the portal 22 in the tunnel, and the fall arrest rope can also reduce the traction load of the steel cable 72, and avoid false triggering of the alarm due to vibration of the steel cable 72.

[0065] On the other hand, the installation method of the above-mentioned large-inclination-angle secondary lining construction traction trolley includes the following steps:

[0066] S1: Adjust the relative position of the upper support frame 21 and the portal 22 by the transverse adjusting assembly 3, so that the center line of the arch-shaped formwork 1 coincides with the tunnel center axis.

[0067] It can be understood that, during installation, after the portal 22 is moved to a set position in the tunnel by the track 8, the arch-shaped formwork 1 is installed, the upper support frame 21 is connected to the top of the arch-shaped formwork 1, and the relative position between the upper support frame 21 and the portal 22 is adjusted by the transverse adjusting assembly 3, so that the center line of the arch-shaped formwork 1 coincides with the tunnel center axis.

[0070] After the trolley is positioned, how to keep the trolley stable during the pouring of concrete on the slope is the key to the quality of the concrete. Therefore, in some optional embodiments, step S3 is further included:

[0071] After the arch-shaped formwork 1 is adjusted to the set position, the portal 22 is fixedly connected with the tunnel through the positioning assembly 6, and the relative position of the portal 22 and the side formwork 12 is fixed through the connecting assembly 4.

[0072] It can be understood that the portal 22 is longitudinally limited through the rail clamping device 62 and the adjustable lead screw 61 connected with the tunnel.

[0073] Further, the adjustable lead screw 61, away from the end connected with the portal 22, is connected with the transverse supporting rod 81 installed on the bottom plate after pouring is completed, so as to longitudinally limit the portal 22.
