Furthermore, the number of the metal chains is two, and the metal chains are respectively fixed on the left side and the right side of the protection frame.

The utility model has the advantages that:

firstly, both sides of the mobile platform are provided with anti-collision devices, and through the arrangement of the anti-collision devices, when the mobile platform is in contact with an obstacle, signals can be transmitted to a power device of the mobile platform in time, and the power device cuts off power to prevent the mobile platform from moving continuously;

secondly, the length of the cross frame at the top of the protective frame is designed to exceed that of the platform base, and the protective frame is directly pushed when encountering an obstacle, so that the mechanical contact of the limit switch is controlled;

thirdly, the protective frame inclines to the two sides of the mobile platform under the gravity condition in a natural state, and when the protective frame is extruded by external force, the protective frame moves inwards, so that the mobile platform can be prevented from being collided with other objects;

fourthly, the protection frame is connected with the L-shaped mounting plate in a hinged mode through the hinge, so that when the protection frame is extruded, the protection frame can be overturned, and when external force is removed, the protection frame can be restored to the initial position due to gravity.

In the figure: 1. a mobile platform base; 2. an L-shaped mounting plate; 21. a base plate; 22. a vertical plate; 3. a protective frame; 4. a limit switch; 5. a stopper; 6. a mechanical link contact; 7. erecting a frame; 8. a cross frame; 9. a hinge; 10. A metal chain; 11. a track.

Detailed Description

The invention will be further explained with reference to the following figures and examples:

referring to fig. 1 to 4, the three-integrated-box moving platform collision-prevention device is connected to both sides of a moving platform base 1, and since the moving platform moves in both directions, therefore, the anti-collision devices are arranged at two sides of the mobile platform and comprise L-shaped mounting plates 2, protective frames 3 are hinged on the bottom plates 21 of the L-shaped mounting plates 2, anti-collision parts are arranged at the tops of the protective frames 3, the protective frame 3 inclines towards the outside, a drawknot piece is fixedly connected between the vertical plate 22 of the L-shaped mounting plate 2 and the protective frame 3, the pulling piece is a flexible pulling piece, a limit switch 4 for controlling the moving platform 1 to move on the track 11 is fixed on the bottom plate 21, the limit switch is connected with a control circuit of the mobile platform, a stop block 5 matched with the limit switch 4 is fixed on the protective frame 3, and the stop block 5 is in contact with a mechanical connecting rod contact 6 of the limit switch 4.

The utility model discloses the process is as follows when using, after installing buffer stop to the both sides of the moving platform 1 of three synthesis casees, if meet the barrier (such as passerby or other objects) when three synthesis case moving platform 1 moves on track 11 (moving platform's weight reaches several tons, the translation rate is fairly slow simultaneously), the barrier will contact with the protection frame 3 of buffer stop at first, and the crashproof portion at protection frame 3 top is extruded gradually slowly, protection frame 3 is when extruding, because the bottom of protection frame articulates on L type mounting panel 2, so will overturn gradually, when protection frame 3 takes place to overturn, dog 5 on protection frame 3 will cooperate with limit switch 4, specifically, dog 5 will extrude limit switch 4's mechanical connecting rod contact 6 gradually, make mechanical connecting rod contact 6 also overturn, when the mechanical connecting rod contact 6 overturns, the control circuit connected with the limit switch 4 disconnects the power device of the mobile platform, so that the mobile platform 1 is prevented from moving continuously, the occurrence of an impact event is effectively avoided, and the safety of people or objects is effectively guaranteed. Additionally, the utility model discloses a L type riser is at diaphragm below still fixedly connected with baffle, through the setting of baffle, can be less than some barriers of moving platform.
