The plurality of brake mechanisms 4 are provided, and all the brake mechanisms 4 are uniformly arranged along the guide slide 11.

The brake mechanism 4 comprises a mounting plate 41, a limit plate 42, a baffle plate 43, an armature 44, an elastic member 45 and an electromagnet 46. The mounting plate 41, the limiting plate 42 and the baffle 43 are made of plastic plates, and the mounting plate 41 is fixed with the upper ends of the supporting legs 121 in the support 12 through screws. The lower end of the limiting plate 42 is welded and fixed with the mounting plate 41. The baffle 43 is arranged obliquely, and the upper end of the baffle 43 is arranged towards the upper end of the inclined section 1. An armature 44 is fixed to the upper end of the baffle 43 by a screw. The middle part of the baffle 43 is fixed with a first metal plate 431 through a screw, the mounting plate 41 is fixed with a second metal plate 411 through a screw, the elastic piece 45 adopts a spring, the upper end of the spring is welded and fixed with the first metal plate 431, and the lower end of the spring is welded and fixed with the second metal plate 411. The lower end of the baffle 43 is hinged with the lower end of the limit plate 42. The electromagnet 46 includes an iron core 461, a wire 462, a power source 463, and a switch 464. The iron core 461, the power source 463 and the switch 464 are all fixed on the supporting leg 121 through screws, the middle part of the lead 462 is wound on the iron core 461 to form a conductive winding, and the switch 464, the power source 463 and the conductive winding are connected in series to form a conductive loop.

In the process of transporting the transportation vehicle 2 upwards along the guide slideway 11, because the lower end of the baffle 43 in the braking mechanism 4 is hinged to the lower end of the limiting plate 42, the baffle 43 is arranged obliquely, and the upper end of the baffle 43 is arranged towards the upper end of the guide slideway 11, the transportation vehicle 2 can press down the upper end of the baffle 43 to smoothly pass through the baffle 43 (at this time, the elastic member 45 is extruded) in the process of moving upwards along the guide slideway 11, and when the transportation vehicle 2 passes through the baffle 43, the baffle 43 is reset under the action of the elastic force of the elastic member 45. So that the stop 43 in the braking mechanism 4 does not hinder the movement of the vehicle 2 during the upward transport of the vehicle 2 along the guide chute 11. Therefore, in the process of moving the transport vehicle 2 up along the guide chute 11, whether the switch 464 in the electromagnet 46 is closed or not does not affect the moving up of the transport vehicle 2.

When the transportation vehicle 2 is transported downwards along the guide slideway 11, the worker is required to close the switch 464 of the electromagnet 46, after the switch 464 of the electromagnet 46 is closed, the conductive winding wound on the iron core 461 is energized, so that the iron core 461 has magnetism, the magnetic iron core 461 attracts the armature 44 at the upper end of the baffle 43, so that the baffle 43 overcomes the elastic force of the elastic member 45 to be laid down, and therefore, in the process that the transportation vehicle 2 is transported downwards along the guide slideway 11, the transportation vehicle 2 cannot be blocked by the baffle 43 and can smoothly move downwards.

When the steel wire rope 31 is broken during the upward transportation or the downward transportation of the transportation vehicle 2, the worker is required to quickly disconnect the switch 464, and after the switch 464 in the electromagnet 46 is disconnected, the iron core 461 in the electromagnet 46 is non-magnetic, so that the armature 44 at the upper end of the baffle 43 is not attracted to the iron core 461, so that the baffle 43 can be supported under the action of the elastic force of the elastic member 45. After the steel wire rope 31 is broken, the transport vehicle 2 can slide downwards rapidly along the lead 462 slideway, and the baffle 43 can be supported by the elastic piece 45, so that the transport vehicle 2 can be blocked by the baffle 43, the condition that the transport vehicle 2 slides downwards and falls to the ground is avoided, articles borne by the transport vehicle 2 and the transport vehicle 2 can be well stored, the condition that the transport vehicle 2 collides with passerby due to the falling to the ground is also avoided, and the transportation safety is improved.

It will be apparent to those skilled in the art that various changes and modifications may be made in the present invention without departing from the spirit and scope of the utility model. Thus, if such modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include such modifications and variations.
