1. the device comprises a beam, 2, a switch, 3, a shifting block, 4, a blocking mechanism, 5, a moving trolley, 41, a support, 42, a guide rail, 43, a sliding block, 44, a stop block, 45, an elastic piece, 46, a magnetic guiding piece, 47 and an electromagnetic block.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention will be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.

The utility model discloses a take safety device's crossbeam, as shown in fig. 1-2, including switch 2, shifting block 3 and stop gear 4, travelling car 5 sets up on crossbeam 1, and generally, travelling car 5 passes through motor drive its motion on crossbeam 1. The shifting block 3 is arranged on the moving trolley 5, the switch 2 is arranged on the cross beam 1, the blocking mechanism 4 is arranged at the end part of the cross beam 1, the switch 2 is used for controlling a driving power supply of the moving trolley 5, when the moving trolley 5 moves on the cross beam 1, the moving trolley moves to the switch 2, if the moving trolley continues to move, the switch 2 is closed through the shifting block 3 arranged on the moving trolley 5, and then the power supply of the moving trolley 5 is cut off, so that the power supply of the moving trolley 5 is lost.

The blocking mechanism 4 comprises a bracket 41, a guide rail 42, a sliding block 43, a baffle 44, an elastic piece 45, a magnetic guiding sheet 46 and an electromagnetic block 47, wherein the bracket 41 is U-shaped, the guide rail 42 is vertically arranged on the bracket 41, and the baffle 44 is arranged on the guide rail 42 in a sliding manner through the sliding block 43, so that the baffle 44 can vertically move. An elastic member 45 is arranged between the bottom of the baffle 44 and the bottom of the bracket 41, and the elastic member 45 can be a spring, and the baffle 44 is pushed to move upwards by the spring. The magnet guiding sheet 46 is arranged at the bottom of the bracket 41, an electromagnetic block 47 is arranged at a corresponding position at the bottom of the bracket 41, when the electromagnetic block 47 is electrified, magnetism is generated, the magnet guiding sheet 47 is attracted, the spring is further compressed, and the upper edge of the baffle 44 is lower than the cross beam 1. When the electromagnet 47 is powered off and the magnetism is small, the baffle 44 is under the action of the spring to push the baffle 44 to move up quickly, so that the moving trolley 5 is blocked, and the moving trolley 5 is prevented from sliding out of the beam 1. The power supply to the electromagnet 47 is controlled by means of the switch 2.

In one embodiment, the switch 2 is a toggle switch or a knife switch.

In one embodiment, the elastic members 45 are at least two symmetrically arranged and are in a number that is a multiple of 2.

In one embodiment, the rails 42 are dovetail rails.

The utility model discloses when using, as shown in fig. 1-2, open switch 2 for travelling car 5 and electro-magnet 47 circular telegram, electro-magnet 47 produces magnetism, pushes down baffle 44, makes elastic component 45 compress, attracts through electro-magnet 47 and draws magnetic sheet 46, and then makes baffle 44 fix the position that is less than crossbeam 1. When the movable trolley 5 is in normal use, the shifting block 3 can not be contacted with the switch 2. If the operator operates by mistake, the movable trolley 5 moves towards the end part of the beam 1, the shifting block 3 is contacted with the switch 2, the switch 2 is closed, and the power supply of the movable trolley 5 and the electromagnet 47 is disconnected. The electromagnet 47 loses magnetism and cannot continuously attract the magnetic guiding sheet 46, and the stop block 44 is driven to move upwards quickly under the restoring force of the elastic piece 45; meanwhile, the movable trolley 5 loses power and can only move by means of inertia, so that the impact on the baffle 44 is reduced.

The above are only preferred embodiments of the present invention, and are not intended to limit the scope of the present invention; the scope of the appended claims should be accorded the broadest interpretation so as to encompass all such modifications and equivalent arrangements as is within the spirit and scope of the present invention.
