Description

Technical Field

[0001] The utility model relates to the technical field of shield tunnel construction, in particular to temporary track hoisting equipment for a shield tunnel. Background Art

[0002] In order to meet people's needs for convenient, comfortable and fast travel, urban rail transit construction is developing more and more rapidly, and more and more tunnel shield construction methods are being used. During the construction of shield tunnels, temporary tracks are usually required to be laid to facilitate the passage of auxiliary vehicles such as construction battery vehicles. After the construction of the shield tunnel is completed, the temporary tracks in the tunnel need to be removed. However, the removal and transportation process of such tracks is time-consuming, which affects the acceptance and handover work. Traditional temporary tracks are removed and transported manually, which is time-consuming and labor-intensive, and is prone to safety accidents.

[0003] Therefore, in view of the above problems, a temporary track hoisting equipment for a shield tunnel is proposed to solve the above problems. Utility Model Content

[0004] Aiming at the deficiencies of the prior art, the utility model develops temporary track hoisting equipment for a shield tunnel. The utility model can hoist and transport the track removed from the tunnel.

[0006] The rails removed from the tunnel are hoisted by electric fall chains, which move left and right on the movable rails, and the movable rails move forward and backward on the mounting frame, driving the electric fall chains to move, thereby hoisting the dismantled rails to the appropriate position on the segment pallet truck. Through reasonable arrangement, the transportation efficiency of the segment pallet truck is improved, while the manual labor is reduced.

[0007] Preferably, the mounting frame includes a fixed rail and a rotating rail. A rotating rail is arranged on the upper end of a support rod on one side of the segment pallet trolley. The rotating rail is connected to the support rod through a rotating shaft. A fixed rail is arranged on the upper end of the support rod on the other side of the segment pallet trolley. The rotating rail and the fixed rail are connected through a detachable connecting part. The movable rail is slidably connected to the fixed rail or the rotating rail.

[0008] By setting a rotating track and turning it to a position perpendicular to the fixed track, the movable track is slidably connected to the fixed track, and a huge gap is generated between the rotating track and the fixed track, which makes it convenient to centrally unload the dismantled tracks on the segment pallet truck through other equipment, thereby improving the efficiency of unloading the dismantling tracks and preventing the rotating track from obstructing the dismantling tracks.

[0009] Preferably, the detachable connecting member includes a mounting plate, mounting bolts and an inclined surface, the contact surface between the rotating track and the fixed track is an inclined surface, a mounting plate is arranged on the rotating track, the mounting plate is overlapped on the fixed track, and the mounting plate is connected to the fixed track by multiple mounting bolts.

[0010] The contact surface between the rotating track and the fixed track is an inclined surface, and the inclined surface is set to limit the rotation direction of the rotating track and reduce the resistance of the movable track during the movement between the two.

[0014] The driving wheel and the driven wheel are clamped on the slide rail to prevent falling off, and the driving wheel is driven to rotate by the motor, thereby driving the first electric pulley or the second electric pulley to move.

[0015] Preferably, a connecting rod is horizontally arranged on the support rod at one end of the segment pallet truck, the connecting rod is away from the fixed track and perpendicular to the fixed track, the connecting rod is connected to the support rod through reinforcing ribs, and fixed rods are arranged on the connecting rods on both sides, and the fixed rod is connected to the movable track through a first electric pulley.

[0016] By setting reinforcing ribs, the installation strength of the connecting rod is improved. By setting fixed rods, the support rods on which the connecting rods are set are evenly stressed, thereby improving the overall structural strength. At the same time, by setting fixed rods, the length of the moving track is extended, so that the electric fall chain can be hoisted outside the segment pallet truck.

[0017] The effects provided in the utility model content are only the effects of the embodiments, not all the effects of the utility model. The above technical solution has the following advantages or beneficial effects:

[0018] The rails removed from the tunnel are hoisted by electric fall chains, which move left and right on the moving rails, and the moving rails move forward and backward on the mounting frame, driving the electric fall chains to move, thereby hoisting the dismantled rails to the appropriate position on the segment pallet truck.

[0027] like Figures 1 to 4 As shown, a temporary track hoisting device for a shield tunnel comprises a segment pallet truck 1, on which a plurality of support rods 2 are symmetrically and vertically arranged, on which a deployable mounting frame 3 is arranged, on which a movable track 4 is slidably arranged, on which an electric fall chain 5 is arranged, and at both ends of the movable track 4, baffles 6 are arranged. The track removed from the tunnel is hoisted by the electric fall chain 5, which moves left and right on the movable track 4, and the movable track 4 moves forward and backward on the mounting frame 3, driving the electric fall chain 5 to move, so as to hoist the disassembled track to a suitable position on the segment pallet truck 1, and through reasonable arrangement, the transportation efficiency of the segment pallet truck 1 is improved, while the manual labor is reduced.

[0028] The mounting frame 3 includes a fixed rail 7 and a rotating rail 8. The rotating rail 8 is arranged on the upper end of the support rod 2 on one side of the segment pallet trolley 1. The rotating rail 8 is connected to the support rod 2 through a rotating shaft 9. The fixed rail 7 is arranged on the upper end of the support rod 2 on the other side of the segment pallet trolley 1. The rotating rail 8 and the fixed rail 7 are connected through a detachable connector. The movable rail 4 is slidably connected to the fixed rail 7 or the rotating rail 8. By setting the rotating rail 8, the rotating rail 8 is turned to a position perpendicular to the fixed rail 7. At this time, the movable rail 4 is slidably connected to the fixed rail 7, and a huge gap is generated between the rotating rail 8 and the fixed rail 7, which facilitates the removal of the rails on the segment pallet trolley 1 through other equipment. The efficiency of removing the removed rails is improved and the rotating rail 8 is prevented from obstructing the removal rails.

[0029] The detachable connecting member includes a mounting plate 10, mounting bolts 11 and an inclined surface 12. The contact surface between the rotating track 8 and the fixed track 7 is the inclined surface 12. The mounting plate 10 is arranged on the rotating track 8, and the mounting plate 10 is overlapped on the fixed track 7. The mounting plate 10 is connected to the fixed track 7 through a plurality of mounting bolts 11. The contact surface between the rotating track 8 and the fixed track 7 is the inclined surface 12. The inclined surface 12 is arranged so as to limit the rotation direction of the rotating track 8 and reduce the resistance of the movable track 4 during the movement between the two.

[0030] A plurality of first electric pulleys 13 are arranged on the moving rail 4, the first electric pulleys 13 are slidably connected to the fixed rail 7 or the rotating rail 8, a second electric pulley 14 is slidably connected below the moving rail 4, and an electric fall chain 5 is arranged on the second electric pulley 14. The moving rail 4 is moved by the first electric pulley 13, and the electric fall chain 5 is moved by the second electric pulley 14.

[0031] The first electric pulley 13 and the second electric pulley 14 both include a housing 15, a driving wheel 16, a driven wheel 17 and a motor 18. The driving wheel 16 and the driven wheel 17 are symmetrically arranged in the housing 15 for rotation. The driving wheel 16 and the driven wheel 17 are clamped on the track. The motor 18 is arranged outside the housing 15, and the output end of the motor 18 is connected to the driving wheel 16. The driving wheel 16 and the driven wheel 17 are clamped on the slide rail to prevent them from falling off, and the driving wheel 16 is driven by the motor 18 to rotate, thereby driving the first electric pulley 13 or the second electric pulley 14 to move.

[0032] A connecting rod 19 is horizontally arranged on the support rod 2 at one end of the segment pallet truck 1. The connecting rod 19 is away from the fixed track 7 and perpendicular to the fixed track 7. The connecting rod 19 is connected to the support rod 2 through a reinforcing rib 20. The connecting rods 19 on both sides are connected with fixed rods 21. The installation strength of the connecting rod 19 is improved by providing the reinforcing rib 20. The support rod 2 provided with the connecting rod 19 is evenly stressed by providing the fixed rod 21, thereby improving the overall structural strength. At the same time, the length of the moving track 4 is extended by providing the fixed rod 21, so that the electric fall chain 5 can be hoisted outside the segment pallet truck 1.

[0033] Working principle: Move the segment pallet truck 1 to the vicinity of the dismantled track, lift the dismantled track of the tunnel through the electric fall chain 5, and lift it onto the segment pallet truck 1. During the lifting process, by moving the mobile rail 4 and the electric fall chain 5, the arrangement of the tunnel dismantling track lifted onto the segment pallet truck 1 is made more reasonable, and more can be transported at one time. After loading is completed, move the segment pallet truck 1 to the unloading position, move the mobile rail 4 so that the mobile rail 4 is located at the fixed rail 7, remove the mounting bolts 11, rotate the rotating rail 8, and then use other equipment to centrally unload or lift it away.

[0034] Although the specific implementation methods of the utility model are described above in conjunction with the accompanying drawings, this does not limit the scope of protection of the utility model. On the basis of the technical solution of the utility model, various modifications or deformations that can be made by technical personnel in this field without creative work are still within the scope of protection of the utility model.
