Description

Slow down device with brake structure

technical field

The present application relates to a descending device for escape in an emergency, in particular to a descending device with a brake assembly.

Background technique

With the acceleration of urbanization, more and more people live in high-rise buildings. Once faced with a fire, escaping is the most natural response for everyone. However, stair access is not a panacea. Blocked, for high-rise buildings, high-rise slow descent is a more effective and efficient choice. However, effective self-controlled slow-down devices are not common. The applicant applied for an escape device with an application number of 2017207036944, named a speed-down device. The self-controlled slow-down device that adjusts the speed through its own mechanical structure, through The intermediate gear set drives the central shaft assembly to rotate in the opposite direction to the drum, and relies on the centrifugal force generated by the brake block of the speed limiting assembly to produce friction on the drum to achieve the purpose of deceleration. The speed limiting effect generated by its own motion is It is adjusted according to the user's weight. Generally speaking, the user can escape slowly without manual operation. However, in some special cases, the user may need to manually operate to limit the descent speed or choose a safer escape after braking suddenly. In a more extreme case, when the speed of the slow descent device may be too fast due to its own structural failure, a slow descent device with self-controlled brakes or speed limit is also required.

Utility model content

The utility model overcomes the above technical problems and provides a slow descending device with a brake structure.

This slow descending device with a brake structure includes a frame, a drum, a cable is wound on the drum, and discs are arranged on both sides of the drum, wherein a brake assembly is fixedly connected to the frame, and the brake assembly includes a brake caliper. The brake calipers are clamped on one or both sides of the disc.

Preferably, the frame includes a main panel and a back load panel, and the brake assembly is fixed on the main panel or the back load panel.

Preferably, the brake assembly further includes a hand brake and a brake line, and the brake line is connected between the hand brake and the brake caliper.

Preferably, the handbrake includes a handle and a wrench, wherein the handle is ring-shaped, and the wrench is arranged in the ring-shaped handle.

Preferably, the disk is a flake disk, and a number of cooling holes are evenly distributed on the disk.

The utility model provides a slow-down device with a brake component. The brake component is added on the basis of the original self-adjusting and speed-controlled slow-down device, so that in special circumstances, the downhill user can adjust the down speed or perform emergency brake.

Detailed ways

Below will further illustrate the utility model with embodiment in conjunction with accompanying drawing.

As shown in Figures 1 to 4, the slow down device of this embodiment includes a frame 10, the frame 10 mainly includes a main panel 11, a back load panel 12 and a plurality of connecting columns between the two panels by screws or riveting 13. A drum 30 is connected to the frame 10 through a central shaft assembly 20, and a cable 40 is wound on the drum 30, wherein the two sides of the drum 30 are discs 31 for pulling the cable 40 together, and the central shaft assembly 20 is connected with a speed-limiting assembly 50, which limits The speed assembly 50 includes a brake shoe 51, the central shaft assembly 20 is in transmission connection with the drum 30 through an intermediate gear set 60, and the brake shoe 51 is in contact with the inner wall of the drum 30 when the drum 30 rolls. The drum 30 drives the brake shoe 51 of the speed limiting assembly 50 at a high speed to produce centrifugal force against the inner wall of the drum 30 to achieve the purpose of deceleration.

In order to achieve the purpose of manually controlling the descending speed or braking, the slow down device also includes a brake assembly 70, as shown in the figure, wherein the brake assembly 70 includes a brake caliper 71, a hand brake 72 and a brake line 73, wherein the brake line 73 is connected to the hand brake 72 and the brake caliper 71 (the brake line 73 also includes the sleeve and the steel wire rope, both of which are prior art, and its structure and connection mode are not described in detail here), the brake assembly 70 is fixed on the main panel 11 or the back bearing panel 12, It can be seen from the figure that in this embodiment, the brake caliper 71 is fixed on the main panel 11, which can be fixedly connected by riveting or bolts. On both sides of the disk 31, when the hand brake 72 is pressed, the brake caliper 71 performs a clamping action on the disk 31 to generate friction on the disk 31. In addition, a number of cooling holes 311 are evenly distributed on the disk 31 , its purpose is to dissipate the heat produced by intense friction as soon as possible when the disc 31 rotates rapidly and brakes, and also can further increase the frictional force of the brake in addition. Simultaneously, handbrake 72 comprises handle 721 and wrench 722, and wherein handle 721 is ring-shaped, and wrench 722 is located in the handle 721 of ring shape, can prevent like this the scene situation of escaping is complicated, causes the situation of automatic braking that other accidents take place, in case When braking is required, the entire handle can also be held by hand without touching the wrench 722 .

The slow descending device with brake assembly provided by the utility model has simple structure and obvious effect, which can effectively avoid accidents caused by excessive descending speed when escaping, and can also brake abruptly under special circumstances. Therefore, those skilled in the art will understand that various changes in form and details can be made without departing from the spirit and scope of the application defined by the claims and their equivalents, all of which belong to the protection of the present utility model scope.
