Problems solved by technology

[0002] At present, the driving method of large-scale movable roofs in China is generally the hydraulic hoist wire rope traction method. This method has the following disadvantages. First, the operation control requires high precision, and the supporting facilities are complicated to operate, and the input cost is large; Second, the hydraulic control system is sensitive to temperature changes, low-temperature operation reliability is low, there are internal and external oil leakage problems, and high operation and maintenance costs; third, the looseness of the wire rope affects the reliability of the transmission, and the runners and the roof move out of sync when the roof is running and so on, causing the rail

Embodiment 1

[0020] The movable roof driving trolley comprises: a car body 1, a motor 2 is connected to the car body, a gear reducer 3 is connected to the motor, a sprocket 4 is connected to the output shaft of the gear reducer, The sprocket is connected to the trolley driving sprocket 6 through a chain 5, the trolley driving sprocket is coaxial with the trolley driving wheel 7, and the car body is connected to a group of driven wheels 8. The trolley One side of the body is connected with a gear device 9, the gear of the gear device meshes with the rack on the fixed roof track beam, the gear device is connected with the power-off brake 17, and a self-locking hydraulic jack is installed on the car body 10. The self-locking hydraulic jack is connected to the sliding support 11, and the sliding support is connected to the spherical hinge support 12.

[0021] In order to prevent the trolley from moving under the influence of wind force, dead weight and load when the trolley is in the open and ...

Embodiment 2

[0023] The above-mentioned movable roof drives the trolley, and the horizontal guide wheel 13 is provided under the car body to maintain the anti-lateral force of the trolley, reduce lateral friction and adapt to the asymmetric deformation of the rails on both sides and the movement of the rails along their own axes. turn.

Embodiment 3

[0025] For the movable roof driving trolley, the front and rear sides of the car body are equipped with anti-turnover devices 14 to maintain the position of the trolley under the action of wind load, earthquake and running horizontal force, and prevent the wheels from derailing.

Abstract

The invention relates to a movable roof driving trolley. Currently, the mode for driving a large movable roof to open and close is generally a dragging mode of a steel wire rope of a hydraulic winch, which has high investment cost, high running and maintaining cost and easy rail trap. The movable roof driving trolley comprises a trolley body (1) to which a motor (2) is connected; the motor is connected with a gear reducer (3); an output shaft of the gear reducer is connected with a chain wheel (4); the chain wheel is connected with a trolley driving chain wheel (6) through a chain (5); the trolley driving chain wheel is coaxial with a trolley driving wheel (7); the trolley body is connected with a group of driven wheels (8); one side of the trolley body is connected with a gearing system (9); gears of the gearing system are meshed with racks on a fixed roof track girder, and the gearing system is connected with a safe brake (17); the trolley body is provided with a self-locking hydraulic jack (10); the self-locking hydraulic jack is connected with a sliding support (11); and the sliding support is connected with a spherical hinge support (12). The movable roof driving trolley is used for driving large movable roofs to open and close.
