Description

Technical Field

[0001] The utility model relates to the technical field of bridge cranes, in particular to a suction cup type steel plate transfer bridge crane. Background Art

[0002] A bridge crane is an industrial equipment used for lifting and moving heavy objects. It is a lifting equipment that is horizontally mounted above workshops, warehouses and material yards to lift materials. In order to assist the steel plates to be stably transported by the bridge crane, a suction cup type steel plate transfer bridge crane is required.

[0003] During use, traditional suction cup type steel plate transfer bridge cranes mostly use the bottom of the suction cup to overlap with the top of the steel plate, and then assist in vacuuming the inside of the suction cup, so as to use the suction cup to move the steel plate. However, during use, traditional suction cup type steel plate transfer bridge cranes only use the bottom of the suction cup to adsorb the steel plate, which can easily lead to the steel plate body and the suction cup being affected by the external environment, resulting in adsorption between the steel plate body and the suction cup, thereby affecting the stable use of the device, and traditional suction cups are difficult to adsorb with the top near the four ends of the steel plate according to different steel plate shapes and sizes, which can easily lead to the suction cup adsorption point being close to the middle of the steel plate, which can easily lead to difficulty in stable adsorption of the steel plate, affecting the stable lifting of the steel plate. Summary of the Invention

[0004] In view of the deficiencies in the prior art, the present invention provides a suction cup type steel plate transfer bridge crane to solve the problems raised by the above background technology.

[0005] The utility model provides the following technical solution: a suction cup type steel plate transfer bridge crane, comprising a slide rail, the side of the slide rail is slidably connected to a sliding frame, the bottom of the sliding frame is fixedly equipped with an electric telescopic rod, the bottom of the electric telescopic rod is fixedly equipped with a fixed frame, the side of the inner wall of the fixed frame is fixedly equipped with an electric push rod, the side of the electric push rod is fixedly equipped with an L-shaped frame, the bottom of the L-shaped frame is fixedly equipped with a side frame, the inner wall of the side frame is slidably connected to the slide frame, the side of the slide frame is fixedly equipped with a connecting plate, the bottom of the connecting plate is fixedly equipped with a suction cup body, the bottom of the side frame is provided with a support frame, and the bottom of the inner wall of the support frame is fixedly equipped with a rubber pad.

[0006] As an optimal technical solution of the present invention, the side frame and the inner wall of the L-shaped frame are rotatably connected with a transmission gear, the side of the transmission gear is fixedly equipped with a threaded rod, and the outer edge of the threaded rod is threadedly connected to the inner wall of the sliding frame.

[0008] As a preferred technical solution of the present invention, a motor is fixedly mounted on the side of the L-shaped frame, a driving gear is fixedly sleeved on the output shaft of the motor, and the convex teeth on the outer edge of the driving gear are meshed with the convex teeth on the outer edge of the transmission gear.

[0009] As a preferred technical solution of the present invention, an auxiliary frame is fixedly mounted on the side of the side frame, an adjusting motor is fixedly mounted on the side of the auxiliary frame, and an output shaft of the adjusting motor is fixedly sleeved with the inner wall of the support frame.

[0010] As an optimal technical solution of the present invention, a mobile motor is fixedly installed on the side of the sliding frame, the output shaft of the mobile motor is fixedly sleeved with a roller, and the side of the roller is rotatably connected to the side of the inner wall of the sliding frame, and the outer edge of the roller is movably sleeved with the inner wall of the slide rail.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. The suction cup type steel plate transfer bridge crane uses a motor and a driving gear in conjunction with each other. The motor drives the driving gear to rotate, and the driving gear drives the transmission gear to rotate, and the transmission gear drives the threaded rod to rotate, so that the threaded rod drives the side of the sliding frame to slide in the inner wall of the side frame, and the sliding frame drives the connecting plate to move, and the electric push rod moves in the inner wall of the fixed frame, so that the electric push rod drives the L-shaped frame to move, thereby facilitating the position adjustment of the adsorption point according to the shape and size of the steel plate.

[0013] 2. The suction cup type steel plate transfer bridge crane is used by adjusting the coordination of the motor and the support frame. After the bottom of the suction cup is adsorbed on the top of the steel plate, the motor is used to drive the support frame to rotate, thereby using the support frame to drive the top of the rubber pad to overlap with the bottom of the steel plate, so as to use the top of the rubber pad to assist in limiting the steel plate to prevent the suction cup from loosening and causing the steel plate to fall off.

[0014] 3. The suction cup type steel plate transfer bridge crane uses an air cylinder in conjunction with the suction cup body, and uses an electric telescopic rod to drive the fixed frame to move downward, thereby using the fixed frame to drive the bottom of the suction cup body to fit the top of the steel plate. Then, the air pump assists the air inside the air cylinder and between the suction cup and the steel plate to be extracted to the outside of the device, thereby assisting the suction cup and the steel plate to be stably adsorbed. Then, by opening the solenoid valve tube, it assists the outside air to enter between the suction cup and the steel plate, thereby assisting the steel plate and the suction cup to be easily separated.
