Description

Technical Field

[0001] The utility model belongs to the technical field of tunnel lining, and particularly relates to a fast-turnover tunnel lining trolley. Background Art

[0002] Tunnel lining refers to a permanent protective structure built on the tunnel wall after tunnel excavation is completed to ensure the stability and durability of the tunnel structure and to prevent weathering, collapse and groundwater infiltration of the surrounding rock.

[0003] The existing fast-turnover tunnel lining trolley drives the driving module to operate through the output shaft of the motor, and the pulley of the driving module cooperates with the belt to drive the roller on the lower side of the tunnel lining trolley to rotate, so that the tunnel lining trolley moves on the guide rail, thereby realizing the fast turnover of the tunnel lining trolley. However, in actual use, when the tunnel lining trolley stops, due to the large weight of the tunnel lining trolley, the inertia of the tunnel lining trolley is also large, so that the tunnel lining trolley still moves to a certain position when it stops, and the accuracy of the moving distance of the tunnel lining trolley is not high. Utility Model Content

[0004] In view of this, the utility model aims to provide a fast-turnover tunnel lining trolley to address the deficiencies of the prior art, which can quickly and stably drive the rollers to rotate while ensuring the self-locking position of the rollers when they stop, thereby achieving fast and stable turnover of the tunnel lining trolley.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is: a fast-turnover tunnel lining trolley, including a mounting base, two left-right symmetrically distributed guide rails are arranged between the tops of the mounting base, a plurality of evenly distributed sliding frames are slidably arranged between the two guide rails, a mounting frame is arranged between the upper surfaces of the sliding frames, a plurality of evenly distributed auxiliary rods 1 are arranged on the upper surface of the mounting frame, a plurality of evenly distributed auxiliary rods 2 are arranged in the middle of the upper surface of the mounting frame, a mold plate is arranged between the tops of the auxiliary rods 1 and 2, and an electric control module for driving the sliding frame to move is also arranged on the sliding frame; hydraulic rod 1 is rotatably arranged on the upper sides of the left and right sides of the sliding frame, hydraulic rod 2 is rotatably arranged in the middle of the left and right sides of the sliding frame, hydraulic rod 3 is rotatably arranged on the lower sides of the left and right sides of the sliding frame, and the telescopic ends of the hydraulic rod 1, hydraulic rod 2 and hydraulic rod 3 are rotatably connected to the mold plate.

[0006] As a further improvement of the utility model, the electric control module includes a roller groove provided in the middle of the upper surfaces of the two guide rails, rollers are rotatably provided at the lower ends of the left and right sides of the sliding frame through a rotating shaft, the rollers are respectively installed in cooperation with adjacent roller grooves, and an electric drive unit for driving the rollers to rotate is also provided on the sliding frame; the electric drive unit includes an installation groove provided inside each sliding frame, a rotating rod is rotatably provided on the upper side of the inner part of the installation groove, synchronous pulleys are fixedly provided at the left and right ends of the rotating rod and a side of the rotating shaft away from the vertical center of the sliding frame, and a transmission device is respectively provided between two vertically adjacent synchronous pulleys. A transmission synchronous belt is arranged, and a driving assembly for driving the rotating rod to rotate is also arranged on the sliding frame; the driving assembly includes worm wheels fixedly sleeved on the left and right sides of the outer arc surface of each rotating rod, and two worms symmetrically distributed on the upper inner side of the sliding frame are rotatably arranged, and the worms are respectively meshed and connected with adjacent worm wheels, and linkage rods are respectively connected between the two adjacent worms in front and behind through couplings, and two motors symmetrically distributed on the left and right sides are arranged on the side of the frontmost sliding frame and the rearmost sliding frame away from the vertical center of the mold plate, and the output shafts of the motors are respectively fixed to the adjacent worms through couplings.

[0008] As a further improvement of the utility model, a rubber pad is provided on the lower surface of the mounting base.

[0009] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0010] First, after the sliding frame drives the mold plate to move to the appropriate position, the hydraulic rod one, hydraulic rod two and hydraulic rod three are driven to operate through the control panel, so that the hydraulic rod one, hydraulic rod two and hydraulic rod three control the external support of the mold plate, thereby completing the subsequent lining pouring and construction.

[0011] Secondly, the four motors are controlled to run synchronously through the control panel, so that the rollers on the outer arc surface of the shaft rotate, causing the rollers to move in the roller grooves, thereby driving the sliding frame to slide between the two guide rails to realize the turnover of the tunnel lining trolley.

The telescopic ends of hydraulic rod one 107, hydraulic rod two 108 and hydraulic rod three 109 are rotatably connected to the mold plate 110.

[0023] like Figure 2 , 3 4, the electric control module includes a roller groove 203 provided in the middle of the upper surface of the two guide rails 102, and rollers 202 are rotatably provided at the lower ends of the left and right sides of the sliding frame 103 through the rotating shaft 201, and the rollers 202 are respectively installed in cooperation with adjacent roller grooves 203, and the sliding frame 103 is also provided with an electric drive unit for driving the rollers 202 to rotate; the electric drive unit includes a mounting groove 204 provided inside each sliding frame 103, and a rotating rod 205 is rotatably provided on the upper side of the inner part of the mounting groove 204, and a synchronous pulley 206 is fixedly sleeved on the left and right ends of the rotating rod 205 and the side of the rotating shaft 201 away from the vertical center of the sliding frame 103, and a transmission is respectively provided between two vertically adjacent synchronous pulleys 206. The driving synchronous belt 207 is provided on the sliding frame 103, and a driving assembly for driving the rotating rod 205 to rotate is also provided; the driving assembly includes a worm wheel 208 fixedly sleeved on the left and right sides of the outer arc surface of each rotating rod 205, and two worms 209 symmetrically distributed on the upper inner side of the sliding frame 103 are rotatably provided, and the worms 209 are respectively meshed and connected with adjacent worm wheels 208, and a linkage rod 210 is connected between the two adjacent worms 209 in front and behind through a coupling, and two motors 211 symmetrically distributed on the side of the frontmost sliding frame 103 and the rearmost sliding frame 103 away from the vertical center of the mold plate 110 are provided, and the output shafts of the motors 211 are respectively fixed to the adjacent worms 209 through couplings.

[0025] During the processing of the tunnel, when it is necessary to drive the tunnel lining trolley to rotate, the four motors 211 are controlled to run synchronously through the control panel 301, so that the output shafts of the motors 211 respectively drive the worm 209 connected thereto to rotate, and all the worm wheels 208 are synchronously rotated through the linkage rod 210 between the two adjacent worm gears 209 in front and behind.

Through the meshing relationship between the worm 209 and the worm wheel 208 and the transmission relationship between the transmission synchronous belt 207 and the synchronous pulley 206, the roller 202 can be driven to rotate quickly and stably while ensuring the self-locking of the position of the roller 202 when it stops, thereby realizing the rapid and stable turnover of the tunnel lining trolley; after the sliding frame 103 drives the mold plate 110 to move to a suitable position, the control panel 301 drives the hydraulic rod 107, the hydraulic rod 208 and the hydraulic rod 3 109 to operate, so that the hydraulic rod 107, the hydraulic rod 208 and the hydraulic rod 3 109 control the external support of the mold plate 110, thereby completing the subsequent lining casting and construction.
