Description

Technical Field

[0001] The utility model relates to the field of construction engineering, in particular to an assembled truss platform transfer trolley. Background Art

[0002] When the truss platform is disassembled in pieces, it needs to be transported by a transfer cart. Common transport carts turn while moving, which can easily generate large centrifugal force and cause the truss platform to slip. Another type of transport cart relies on tracks, but laying tracks for turning consumes more steel, and the tracks take up more space on the site, which is not conducive to disassembly and is not convenient for the truss platform to rotate horizontally on the spot. Choose a suitable transfer outlet. Utility Model Content

[0003] The technical problem to be solved by the utility model is an assembled truss platform transfer trolley, which can allow the trolley to rotate horizontally on the spot and does not rely on track turning, so as to facilitate the piece-by-piece transfer of the disassembled truss platform and select a suitable transfer outlet for transfer.

[0004] In order to solve the above problems, an assembled truss platform transfer trolley is adopted, including:

[0005] truss platform;

[0006] Axle seat, which is installed at the bottom of the truss platform;

[0007] an axle, which is rotatably connected to the axle seat and has a worm gear disposed in the center thereof;

[0008] Wheels, which are coaxially fixed to both ends of the axle;

[0009] a first turbine reduction box, which is connected to the worm gear in the middle of the axle;

[0010] The first motor has an output end extending into the first turbine reduction box for transmission connection;

[0011] a screw lift spaced fore and aft of the axle, the screw lift having a center support secured to a lower chord of the truss platform;

[0012] A sliding shoe is fixed to the output end of the lower end of the screw lift;

[0013] Connecting rod, one end of which is hinged to one side of the sliding shoe

[0014] an internally threaded sleeve hinged to the other end of the connecting rod;

[0015] A screw, one end of which is threadedly connected to the internal threaded sleeve, and the other end of which is coaxially provided with a worm;

[0016] a second turbine reduction box, which is connected to the worm gear at the other end of the screw;

[0017] The second motor has an output end extending into the second turbine reduction box for transmission connection;

[0018] The arc-shaped track is used to slide the sliding shoe and is installed on the lower side of the second turbine reduction box.

[0019] With this structure, when the trolley is moving, the screw lifter lifts the curved track, and when turning, the curved track is lowered and driven by the second motor and the second turbine reducer; the screw and the internal threaded sleeve can realize the telescopic function, so that the sliding shoe can move along the curved track, thereby realizing the horizontal turning function in place. When the turn is completed, the curved track is lifted again and the sliding shoe is reset.

[0020] As a further improvement of the present invention, the axle seat, axle, wheel, first turbine reduction box and first motor are arranged in parallel in multiple groups at intervals on the bottom surface of the truss platform.

[0021] Such a structure can ensure smooth transportation of the truss platform.

[0022] As a further improvement of the present invention, the screw lifts are arranged in a row of two and are linked by a transmission rod. The transmission rod is driven by a third turbine reducer. The third turbine reducer is arranged between the two screw lifts. The third turbine reducer is connected to the output end of the third motor. The third motor is installed on the truss platform.

[0023] With this structure, two screw lifts in a row are linked together, making the truss platform more stable.

[0024] As a further improvement of the present invention, the sliding shoe includes a shell, in which two rows of upper and lower limiting rollers are installed, and the curved track is made of I-beams, and the two ends of the upper row of limiting rollers are respectively mounted on the two side walls of the shell and pressed against the upper flange of the curved track; one end of the lower row of limiting rollers is mounted on the side wall of the shell, and the other end faces the web of the curved track, and the upper side of the lower row of limiting rollers presses against the lower side of the upper flange of the curved track.

[0025] With such a structure, the limiting roller can easily move along the arc track and drive the arc track to move up and down.

[0026] As a further improvement of the present invention, the second turbine reducer is connected to transmission screws on both sides, and the transmission method is that when the screw on one side is retracted into the internal threaded sleeve, the screw on the other side extends from the internal threaded sleeve on the other side.

[0027] Such a structure is adopted to ensure the translation and rotation of the entire truss platform.

[0028] As a further improvement of the present invention, the screw lift, sliding shoe, connecting rod, internal threaded sleeve, screw, second turbine reducer, second motor and arc track are arranged in groups, and each two groups are paired and distributed in the form of concentric circles on the front and rear sides of the truss platform.

[0029] With such a structure, the components are distributed in concentric circles, and when rotating, the centers of the circles are the same, so the rotation is more stable.

[0030] The truss platform includes a plurality of rows of main trusses arranged at intervals, and secondary trusses arranged crosswise and vertically between adjacent main trusses.

[0031] The use of such a truss platform makes it easy to install transfer trolley parts. BRIEF DESCRIPTION OF THE DRAWINGS
