Description

Technical Field

[0001] The utility model belongs to the technical field of tunnel lining, in particular to a tunnel lining trolley material placing machine. Background Art

[0002] The tunnel lining trolley is a large-scale mechanical equipment designed specifically for tunnel construction. It is mainly used for concrete lining operations on the inner wall of the tunnel. It integrates functions such as walking, formwork installation, concrete pouring, vibration, and maintenance, which significantly improves the efficiency and quality of tunnel construction.

[0003] The existing tunnel lining trolley placing machine drives the rotating seat where the feeding pipe is located to rotate by a motor, so that the feeding pipe corresponds to the placing pipe that needs to be fed, and then the driving module drives the feeding pipe to dock with the placing pipe, and then the concrete is delivered by the concrete pump, so that the concrete passes through the feeding pipe and the placing pipe and then is delivered into the concrete pipe, so as to realize the placing of the tunnel lining trolley. However, in actual use, when the feeding pipe is driven by the motor to rotate, due to the relatively simple driving structure, the feeding pipe and the placing pipe may be offset due to the inertia of rotation after long-term use, affecting the subsequent docking and causing great trouble to the work. Utility Model Content

[0007] As a further improvement of the present utility model, the rotation module includes a spline rotatably arranged in the middle of the upper surface of the base, the spline is installed in cooperation with the spline sleeve, and the base is also provided with an electric drive unit for driving the spline to rotate; the electric drive unit includes a gear fixedly sleeved on the outer arc surface of the lower end of the spline, two symmetrically distributed supports are arranged at the inner bottom end of the base, two symmetrically distributed guide rails are arranged between the two supports, two adjustment seats are slidably arranged between the outer arc surfaces of the two guide rails, the two adjustment seats are centrally symmetrically distributed with respect to the central axis of the base, rack plates are arranged on the upper surfaces of the two adjustment seats, the rack plates are meshed with the gears, and a drive assembly for driving the adjustment seat to move is also provided on the support; the drive assembly includes a bidirectional screw rod rotatably arranged between the middle parts of the two supports, the two adjustment seats are threadedly connected to the bidirectional screw rod, a motor is arranged on the right side surface of the right support, and the output shaft of the motor is fixed to the bidirectional screw rod by a coupling.

[0008] As a further improvement of the utility model, a rubber pad is bonded and fixed to the lower surface of the connecting plate.

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

[0010] Firstly, the telescopic end of the second hydraulic rod drives the sliding of the feed pipe and the rotating seat through the connecting seat, so that the feed pipe is inserted into the adjacent conical tube to realize fast and self-determined docking. The concrete entering the feed pipe is transported into the concrete pipe through the distribution pipe. After the concrete pipe completes pouring of a working area, the external concrete delivery pump stops running. After the second hydraulic rod drives the feed pipe away from the conical tube, the rotating seat is driven by the motor to continue to rotate, so that the two feed pipes on the rotating seat correspond to the distribution pipe of the next pouring area, realizing fast and stable distribution.

[0011] Secondly, by regulating the synchronous operation of the four hydraulic rods, the telescopic ends of the four hydraulic rods are extended or retracted synchronously, the height of the fabric pipe is adjusted quickly and stably, and the applicability of the fabric pipe is improved.

[0012] Thirdly, the output shaft of the motor drives the bidirectional lead screw connected to it to rotate, and the threaded relationship between the bidirectional lead screw and two adjustment seats symmetrically distributed in the center drives the two adjustment seats to move in opposite directions, thereby making the two rack plates drive the gears to rotate through the meshing relationship with the gears, so that the spline drives the rotating seat to rotate through the spline sleeve, and the threaded relationship between the bidirectional lead screw and the adjustment seat and the meshing relationship between the rack plate and the gear make the two feed pipes on the rotating seat quickly and stably correspond to the distribution pipes that need to transport materials.

[0013] Fourthly, the rubber pad can be used to buffer the gap between the base and the tunnel lining trolley. When the connecting plate is installed on the tunnel lining trolley by screwing the threads with an external tool, it can effectively avoid damage to the base due to excessive installation force during installation.
