[0023] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] As attached Figure 1-5 As shown, the block brake mechanism of the planetary reduction assembly of an elevator traction machine described in the utility model includes a machine base 1, a motor 2, a traction sheave assembly 3, a brake disc 4, an end cover 5 and a block brake 6. The motor 2 and the end cover 5 are respectively fixedly mounted on both sides of the machine base 1; the machine base 1 is an internal hollow structure, and the traction sheave assembly 3 is installed in the hollow structure.

[0025] The traction sheave assembly 3 includes a traction sheave body 31, a shell 32, and a planetary gear assembly 33 arranged in the shell 32. The shell 32 is fixedly mounted on the inner circumferential wall of the traction sheave body 31. By arranging the planetary gear assembly 33 in the shell 32, it becomes an integrated structure with the shell 32, which is convenient for transportation and installation; the planetary gear assembly 33 extends to both ends and forms an extended end 331. The extended ends 331 of the planetary gear assembly 33 both extend out of the machine base 1 and respectively cooperate with the motor 2 and the end cover 5. Specifically, the extended end 331 of the planetary gear assembly 33 close to the motor 2 cooperates with the output shaft of the motor 2, and the motor 2 drives the traction sheave body 31 through the planetary gear assembly 33.

[0026] A mounting portion 11 is provided on the side of the base 1 away from the motor 2. In this embodiment, the base 1 and the mounting portion 11 of the base 1 are integrally formed, and the brake disc 4 is fixedly mounted on the extended end 331 of the planetary gear assembly 33 away from the motor 2, and the brake disc 4 is located in the mounting portion 11 of the base 1, and the end cover 5 is connected to the outer end surface of the fixed mounting portion 11 and closes the outer end surface of the mounting portion 11. The inner side of the end cover 5 has a protruding structure 51, and a connecting groove 52 is opened at the center of the protruding structure 51. The extending end 331 of the planetary gear assembly 33 away from the motor 2 extends into the connecting groove 52 and rotates with the end cover 5 through a bearing 53; compared with the prior art, installing the brake disc 4 in the mounting portion 11 of the base 1 can not only ensure the connection stability, but also effectively reduce the length of the equipment, thereby reducing the space occupancy of the equipment. In addition, the end cover 5 closes the outer end surface of the mounting portion 11, which can reduce the noise generated when the brake disc 4 is braked to a certain extent.

[0027] There are two block brakes 6, which are respectively fixedly mounted at both ends of the mounting portion 11 of the machine base 1 and are symmetrically arranged to ensure a stable braking effect of the block brake 6. Openings 111 are provided at both ends of the mounting portion 11. The two block brakes 6 respectively pass through the openings 111 at both ends of the mounting portion 11 and brake the brake disc 4. Specifically, the block brake 6 includes a releaser 61 and a brake block 62. The releaser 61 is connected and fixed to the outer side of the end of the mounting portion 11. The brake block 62 is mounted on the releaser 61. The releaser 61 is used to control the brake block 62, and the brake block 62 passes through the opening 111 of the mounting portion 11 to brake the brake disc 4.

[0028] As attached Figure 4 As shown, in this embodiment, a cambered surface structure 621 is provided on the side of the brake block 62 close to the brake disc 4 , and the cambered surface structure 621 matches the outer peripheral wall of the brake disc 4 , thereby ensuring the braking effect of the brake block 62 .

[0029] By symmetrically arranging the block brake 6 at both ends of the mounting portion 11, not only is stable braking of the brake disc 4 by the brake block 62 ensured, but the brake block 62 is also designed to pass through the opening 111 of the mounting portion 11 to brake the brake disc 4, thereby reducing the width of the entire device and thereby reducing the space occupancy of the device.

[0030] In this embodiment, a plurality of heat dissipation openings 112 are provided on the mounting portion 11 of the base 1 , through which the heat generated when the brake block 62 brakes the brake disc 4 can be quickly dissipated, thereby ensuring heat dissipation efficiency.

[0031] A plurality of hanging rings 12 are integrally formed on the upper end of the machine base 1 , and a supporting foot structure 13 is integrally formed on the lower corner of the machine base 1 .

[0032] The above are only specific application examples of the present utility model and do not constitute any limitation to the protection scope of the present utility model; any technical solutions formed by equivalent transformation or equivalent replacement fall within the scope of protection of the present utility model.
