Description

[Technical field]

[0001] The utility model belongs to the technical field of raw material equipment of a sintering system, and in particular relates to a bucket wheel of a reclaimer with a fixed-point braking function. [Background technology]

[0002] The bucket wheel mechanism consists of two parts: a slewing bearing and a driving device, which are used to make the arm swing left and right. The existing bucket wheel mechanism driving device rotates the bucket through a motor, a reducer, a pin coupling, and a chain. During operation, the bucket needs to be replaced regularly after running for a period of time. The braking of the bucket wheel mechanism is generally achieved by stopping the motor drive, so the bucket cannot stop at a fixed point after the drive stops, and the bucket wheel mechanism can rotate arbitrarily, causing the bucket to not rotate in place, affecting the maintenance personnel's replacement of the bucket and personnel safety. [Contents of the utility model]

[0003] The utility model aims to provide a reclaimer bucket wheel with a fixed-point braking function to solve the problem that the existing bucket wheel mechanism can rotate arbitrarily after stopping, resulting in the bucket not being able to rotate into place.

[0004] The utility model adopts the following technical scheme: a reclaimer bucket wheel with a fixed-point braking function, comprising a motor, the output shaft of the motor is connected to a reducer, the output shaft of the reducer is connected to a transmission sprocket through a low-speed coupling, and the transmission sprocket is connected to the bucket wheel through a transmission chain; a high-speed coupling is connected to the output shaft of the motor, and the high-speed coupling is a steel ball type soft-start coupling, which has a brake wheel inside;

[0005] Among them, the transmission sprocket is used to drive the bucket wheel to rotate under the drive of the motor; the brake wheel in the high-speed coupling is used to achieve fixed-point parking of the bucket wheel by opening or closing it.

[0006] Furthermore, the model of the high-speed coupling is SGAQZ55-4, and the model of the brake wheel is YWZ5-400 / 80.

[0007] Furthermore, it also includes a base, the bucket wheel is installed on the base, a bracket is provided on the base, and the driving sprocket is fixed to the top of the bracket through a bearing seat.

[0008] The beneficial effect of the utility model is that the driving mechanism can be braked or not by closing and opening the brake wheel in the high-speed coupling, ensuring that the hopper stops at the required position and remains stationary, so that personnel can smoothly reverse the hopper, replace it or perform maintenance, thus solving the original problem of arbitrary rotation and unsafe maintenance operations.

[0011] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0012] The utility model provides a bucket wheel of a material reclaimer with a fixed-point braking function, wherein the bucket wheel mechanism involved is a working mechanism for reclaiming materials, including a bucket wheel and a driving device thereof. Bucket wheels are divided into three types: plain, semi-plain and plain. The bucket of the plain bucket wheel has no bucket bottom, and a circular arc baffle fixed on the arm is used to block the bulk material in the bucket in the non-discharging area, and the bulk material slides on the circular arc baffle. In the discharging area, there is no circular arc baffle but a fixed inclined chute. When the bucket rotates to the discharging area with the wheel body, the material in the bucket slides onto the belt conveyor through the inclined chute under the action of its own weight. Its discharging interval is large, so the bucket wheel has a high rotation speed, which can improve the operating capacity and can unload relatively sticky materials. The structure of the semi-plain bucket wheel is similar to that of the plain bucket wheel, except that the bucket wall is extended to the center of the bucket wheel for a section, so that the distance between the circular arc baffle and the wheel body is increased, so as to reduce the possibility of material jamming between the circular arc baffle and the wheel body. The bottom of each bucket of the formatted bucket wheel is a fan-shaped inclined chute, but there are fixed side baffles in the non-discharging area. When the bucket rotates with the wheel body to a certain height, the bulk material in the bucket begins to slide along the fan-shaped inclined chute to the center of the bucket wheel. When the bucket reaches the discharging area, the bulk material slides to the belt conveyor through the inclined chute and the discharging plate because there is no side baffle to block it. The formatted bucket wheel is slow to unload and requires a larger bucket wheel diameter, but it will not cause material jamming and is suitable for hard materials. Among the three types of bucket wheels, the formatless one is the most widely used. There are two transmission methods for bucket wheels: mechanical and hydraulic, and generally no speed regulation is required.

[0013] like Figure 1 As shown, a reclaimer bucket wheel with a fixed-point braking function of the utility model comprises a motor 1, the output shaft of the motor 1 is connected to a reducer 3, the output shaft of the reducer 3 is connected to a transmission sprocket 6 through a low-speed coupling 4, and the transmission sprocket 6 is connected to a bucket wheel 8 through a transmission chain 7; a high-speed coupling 2 is connected to the output shaft of the motor 1, and the high-speed coupling is a steel ball soft-start coupling with a brake wheel therein; wherein the transmission sprocket 6 is used to drive the bucket wheel 8 to rotate under the drive of the motor 1; the brake wheel in the high-speed coupling 2 is used to achieve a fixed-point parking of the bucket wheel 8 by opening or closing it. Without changing the existing motor and reducer, the device adds a high-speed coupling 2 with a brake wheel, and uses the opening and closing of the brake wheel to achieve the effect of starting and stopping the bucket wheel at a fixed point.

[0014] In some embodiments, the model of the high-speed coupling 2 is SGAQZ55-4, and the model of the brake wheel is YWZ5-400 / 80.

[0015] In some embodiments, a base 9 is further included, the bucket wheel 8 is mounted on the base 9 , a bracket 10 is provided on the base 9 , and the drive sprocket 6 is fixed to the top of the bracket 10 through a bearing seat 5 .

[0016] The utility model provides a method for using a reclaimer bucket wheel with a fixed-point braking function as follows: start the motor 1, and drive the bucket wheel 8 to rotate through the reducer 3, the low-speed coupling 4, the transmission sprocket 6 and the transmission chain 7; when it is necessary to stop the machine for maintenance or replace the bucket, the motor 1 can be stopped, and the rotation of the bucket wheel 8 can be braked by closing the brake wheel in the high-speed coupling 2, and the opening and closing of the brake wheel can achieve the effect of starting and stopping the bucket wheel at a fixed point.
