Problems solved by technology

Because the gantry crane is often exposed to some bad weather conditions, the crane will slide on the track or even fall off, which will bring safety hazards to personal and mechanical equipment
In addition, many rail clamping devices of gantry cranes have high cost, complex structure, many installation procedures, cumbersome operation, and are not easy to observe.

Embodiment Construction

[0019] These drawings are all simplified structural diagrams, and only illustrate the basic structure of the present invention in a simple manner, so only components related to the present invention are shown in the drawings.

[0020] Such as Figure 1 to Figure 4 As shown, the present invention is a novel gantry crane rail clamp. When the device works, the motor shaft 21 of the motor 20 is connected with the cylindrical cam 1 through the connection key 12. When the motor 22 is started, the cylindrical cam 1 is driven to rotate, and the cylindrical cam 1 passes through the The follower 3 slides in the cam groove 10 to drive the driven shaft 4 to move straight down, and the driven shaft pushes the guide rod 7 to move together. One end of the guide rod 7 is connected to the clamp slider. When the driven shaft 4 moves downward, it drives the clamp slider 17 to move downward in a straight line in the clamp chute 18. The clamp slider 17 is connected to the connecting rod through th...

Abstract

The invention relates to a novel portal crane rail clamping device. The device is composed of a motor, a box shell, a clamp, a baffle, a cam guide rod, a cylindrical cam, a driven shaft, a cam shell and the like. A motor shaft of the motor is connected with the cylindrical cam through a connecting key, the cylindrical cam is driven to rotate when the motor is started, the cylindrical cam drives the driven shaft to move downwards through a cam groove, and the driven shaft pushes the guide rod. One end of the guide rod is connected with the clamp; and when the driven shaft moves downwards, a sliding block in the clamp is driven to move downwards, and the sliding block is connected with the clamp to clamp a track. The device is simple in structure and convenient to operate, can play a good anti-falling and anti-slipping effect, well solves the defects that an original portal crane rail clamping device is tedious in operation, not easy to observe and the like, and can effectively guarantee the operation safety of a portal crane.

Description

technical field [0001] The invention belongs to the technical field of crane machinery, and in particular relates to a rail clamp for a gantry crane. [0002] technical background [0003] Gantry cranes are widely used in cargo handling, viaduct construction and other industries. Because the gantry crane is often exposed to some bad weather conditions, the crane will slide on the track or even fall off, which will bring safety hazards to personal and mechanical equipment. In addition, many rail clamping devices of gantry cranes have high cost, complex structure, many installation procedures, cumbersome operations, and are difficult to observe. Contents of the invention [0004] In view of the above-mentioned problems existing in the current market products, the purpose of the present invention is to provide a gantry crane rail gripper with simple structure, simple operation, convenient installation and maintenance, and low cost to meet the working requirements of gantry cr...
