Description

Technical Field

[0001] This utility model relates to elevators, and more particularly to an elevator brake pad. Background Technology

[0002] Elevator brake pads are devices used to provide braking force when an elevator stops or in an emergency, ensuring that the elevator comes to a smooth stop.

[0003] The elevator brake pads generate heat due to friction during operation, and their poor heat dissipation performance can lead to a short service life. Utility Model Content

[0004] Purpose of the utility model: The purpose of this utility model is to provide an elevator brake pad with good heat dissipation performance.

[0005] Technical solution:

[0006] An elevator brake pad, comprising:

[0007] The main body is provided with mounting holes;

[0008] Two braking assemblies are located on both sides of the main body. Each braking assembly includes a heat transfer pad and several braking pads. One side of the heat transfer pad is connected to the main body, and the several braking pads are all connected to the other side of the heat transfer pad. The several braking pads are spaced apart to form a ring.

[0009] Optional, also includes:

[0010] The positioning block connected to the brake pad;

[0011] Positioning holes are provided in the heat transfer pad;

[0012] The positioning groove is provided in the main body;

[0013] The positioning block, the positioning hole, and the positioning groove all fit together.

[0014] Optionally, the positioning block, positioning hole, and positioning groove are all non-rotational in shape along the radial cross-section of the main body.

[0015] Optional, also includes:

[0016] The limiting post connected to the brake pad;

[0017] A limiting hole is provided in the heat transfer pad;

[0018] A limiting groove is provided in the main body;

[0019] fastener;

[0020] The limiting post, the limiting hole, and the limiting groove all fit together, and the fastener passes through the main body and is threadedly connected to the limiting post.

[0021] Optionally, it also includes a receiving hole and a countersunk hole both provided in the main body, one end of the receiving hole is connected to the limiting groove, the other end of the receiving hole is connected to the countersunk hole, at least part of the fastener is located in the receiving hole, and the head of the fastener is located in the countersunk hole.

[0038] Example 1

[0039] like Figures 1-3This embodiment provides an elevator brake pad, including: a main body 1, the main body 1 having a mounting hole 11; two braking components 2 located on both sides of the main body 1, the braking components 2 including a heat transfer pad 21 and a plurality of brake pads 22, one side of the heat transfer pad 21 being connected to the main body 1, and the plurality of brake pads 22 being connected to the other side of the heat transfer pad 21, the plurality of brake pads 22 being spaced apart to form an annular part.

[0040] Specifically, the main body 1 is used to support the mounting hole 11, which is used to cooperate with the relevant components of the elevator, thereby facilitating the installation of the elevator brake pads of this solution on the elevator; the brake pad 22 is used to provide braking force. Since several brake pads 22 are spaced together to form a ring, there is a gap 23 between adjacent brake pads 22. The gap 23 facilitates heat dissipation of the brake pad 22 and ensures good heat dissipation performance. It should be noted that the size of the gap 23 should not be too large, otherwise it will lead to poor continuous braking performance of the brake pad 22. The material of the brake pad 22 can be asbestos-based material, semi-metallic material, etc. The number of brake pads 22 is not limited and can be two, three, etc.; the heat transfer pad 21 is used to transfer the heat generated by the brake pad 22 to the main body 1 and dissipate it to the outside through the main body 1, further facilitating heat dissipation of the brake pad 22 and further ensuring good heat dissipation performance. The material of the heat transfer pad 21 can be copper material, aluminum-based composite material, etc.

[0041] Furthermore, such as Figures 3-7 It also includes: a positioning block 221 connected to the brake pad 22; a positioning hole 211 provided on the heat transfer pad 21; and a positioning groove 12 provided on the main body 1; wherein the positioning block 221, the positioning hole 211, and the positioning groove 12 are all fitted together.

[0042] Specifically, the positioning block 221, the positioning hole 211, and the positioning groove 12 all cooperate to facilitate the radial positioning of the brake pad 22 and the heat transfer pad 21 along the main body 1, preventing the brake pad 22 and the heat transfer pad 21 from moving radially along the main body 1. The number of positioning blocks 221 is not limited and can be two, three, etc., preferably two, and the two positioning blocks 221 are axially symmetrical about the brake pad 22.

[0043] Furthermore, such as Figures 3-7 The positioning block 221, positioning hole 211, and positioning groove 12 are all non-rotational in shape along the radial section of the main body 1. Specifically, when there is only one positioning block 221, the non-rotational shape helps to prevent the brake pad 22 and heat transfer pad 21 from moving radially along the main body 1. The non-rotational shape can be rectangular, elliptical, or trapezoidal, etc.

[0044] Furthermore, such as Figures 3-7It also includes: a limiting post 222 connected to the brake pad 22; a limiting hole 212 provided on the heat transfer pad 21; a limiting groove 13 provided on the main body 1; and a fastener 3; wherein the limiting post 222, the limiting hole 212, and the limiting groove 13 are all fitted together, and the fastener 3 passes through the main body 1 and is threadedly connected to the limiting post 222.

[0045] Specifically, the limiting post 222, limiting hole 212, limiting groove 13 and fastener 3 facilitate the axial positioning of the brake pad 22 and heat transfer pad 21 along the main body 1, preventing the brake pad 22 and heat transfer pad 21 from moving along the main body 1. The number of limiting posts 222 is not limited and can be two, three, etc. The fastener 3 can be screws, bolts, etc.

[0046] Furthermore, such as Figure 3 It also includes a receiving hole 14 and a countersunk hole 15 both provided in the main body 1. One end of the receiving hole 14 is connected to the limiting groove 13, and the other end of the receiving hole 14 is connected to the countersunk hole 15. At least part of the fastener 3 is located in the receiving hole 14, and the head 31 of the fastener 3 is located in the countersunk hole 15.

[0047] Specifically, the receiving hole 14 is used to receive at least part of the fastener 3; the countersunk hole 15 is used to receive the head 31 of the fastener 3, preventing the head 31 of the fastener 3 from protruding from the side surface of the main body 1, and ensuring good smoothness of the side surface of the main body 1.

[0048] Furthermore, such as Figure 1 The spacing 23 between adjacent brake pads 22 is equal. Specifically, the equal spacing 23 facilitates both uniform heat dissipation of the brake pads 22 and uniform distribution of the brake pads 22, thereby improving the braking stability of the elevator.

[0049] Furthermore, such as Figure 2 The two braking components 2 are arranged symmetrically about the main body 1. Specifically, the symmetrical arrangement facilitates good braking symmetry of the braking components 2.

[0050] Furthermore, such as Figure 3 The thickness of the brake pad 22 is greater than the thickness of the heat transfer pad 21. Specifically, the relatively larger thickness of the brake pad 22 helps to ensure good braking performance of the brake pad 22 and prevents the brake pad 22 from being easily damaged; the relatively smaller thickness of the heat transfer pad 21 helps to minimize the thickness of the elevator brake pad in this solution while ensuring heat transfer performance.

[0051] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
