BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drive device for a bucket elevator of a continuous unloader.

[0002]

2. Description of the Related Art In recent years, a continuous unloader has been used as a cargo-handling machine in place of an unloader with a grab. The continuous unloader is generally a rail laid on a quay 1 as shown in FIG. A swing frame 5 having a tiltable boom 4 is provided on a traveling frame 3 capable of traveling on the vehicle 2, and a bulk 7 in a hold 6 is provided at the tip of the boom 4.
Conveyor 9 capable of suspending a bucket elevator 8 which can be scraped off and lifted out of the hold 6 and transporting the loose pieces 7 scraped by the bucket elevator 8 to the base end side of the boom 4 in the boom 4. And an unloading conveyor 10 capable of unloading the bulk material 7 fed from the boom conveyor 9 via the chute 11 out of the running frame 3 is provided on the traveling frame 3. ing.

In the continuous unloader, the hold 6
The bulk material 7 in the inside is scraped off by the bucket elevator 8 and loaded out of the hold 6, conveyed by the boom conveyor 9 from the distal end side of the boom 4 to the proximal end side, and the chute 1
1, falls onto the unloading conveyor 10, and is unloaded outside the traveling frame 3 by the unloading conveyor 10.

On the other hand, as shown in FIGS. 4 to 6, a driving device for the bucket elevator 8 drives an endless chain 13 to which a number of buckets 12 for scraping loose pieces are attached. For example, a hydraulic motor 16 is mounted integrally with the drive shaft 15 of the sprocket 14 and a torque arm 19 fixed to the motor 16 is mounted on a main body frame 18 supporting the drive shaft 15 via a bearing 17.
Are connected via a support frame 20 projecting from the main body frame 18 and a link 21 pivotally connected to the support frame 20, and further provided protruding from the main body frame 18. A bracket 23 is erected on the auxiliary frame 22, and a brake caliper 25 is provided on the bracket 23, which can hold and open both sides of a brake disk 24 integrated with the drive shaft 15.

[0005]

However, as described above, the auxiliary frame 2 protruding from the main body frame 18 is required.
If the brake caliper 25 which can hold and open both sides of the brake disc 24 integral with the drive shaft 15 is provided on the bracket 23, the auxiliary frame 22 and the auxiliary frame 22 are attached when the brake caliper 25 is mounted. It is necessary to align the brake caliper 25 with the brake disc 24 by interposing the liner between the bracket 23 and the brake caliper 25. When an elastic body is interposed, the relative displacement between the brake disc 24 and the brake caliper 25 occurs due to the displacement of the elastic body, and the brake disc 24 comes into contact with the brake caliper 25 even during braking. Had.

In view of such circumstances, the present invention makes it unnecessary to align the brake caliper with the brake disc by the liner, and even when the elastic body for vibration isolation is displaced, the misalignment between the brake disc and the brake caliper occurs. It is an object of the present invention to provide a bucket elevator drive device of a continuous unloader that can prevent the occurrence of the problem.

[0007]

According to the present invention, an endless chain to which a number of buckets for scraping are mounted is driven and a drive shaft integrally provided with a brake disk is supported via a bearing. In a bucket elevator driving device for a continuous unloader comprising a main body frame and a torque arm fixed to a motor directly connected to the drive shaft, a support bracket provided with a brake caliper capable of holding and opening both surfaces of the brake disk. Are integrally attached to the torque arm.

[0008]

Therefore, the brake caliper can be mounted on a support bracket that is integral with the torque arm fixed to the motor. Therefore, when the brake caliper is mounted, the liner is moved between the auxiliary frame and the bracket when the brake caliper is mounted as in the conventional case. It is no longer necessary to align the brake caliper with respect to, and if an elastic body is interposed between the bearing and the body frame to reduce vibration and noise in the drive device, However, the relative center of the brake disc and the brake caliper does not deviate, so that the brake disc does not contact the brake caliper except during braking.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

FIGS. 1 and 2 show an embodiment of the present invention. In the drawings, the portions denoted by the same reference numerals as those in FIGS. 3 to 6 represent the same components, and the basic configuration is shown in FIGS. 6 is the same as the conventional one shown in FIG.
As shown in FIGS. 1 and 2, a support bracket 26 is integrally attached to the torque arm 19, and a brake caliper 25 is provided on the support bracket 26 so as to hold and open both surfaces of a brake disk 24 integrated with the drive shaft 15. On the point.

Since the brake caliper 25 can be attached to the support bracket 26 integral with the torque arm 19 fixed to the motor 16, the structure shown in FIG.
6, it is not necessary to align the brake caliper 25 with the brake disc 24 by fitting a liner between the auxiliary frame 22 and the bracket 23 when the brake caliper 25 is mounted. When an elastic body is interposed between the bearing 17 and the main body frame 18 in order to reduce vibration and noise in the above, even if the elastic body is displaced, the relative center of the brake disc 24 and the brake caliper 25 is shifted. This prevents the brake disc 24 from contacting the brake caliper 25 except during braking.

In this way, the alignment of the brake caliper 25 with the brake disc 24 by the liner can be dispensed with, and the displacement of the brake disc 24 and the brake caliper 25 occurs even when the vibration-proof elastic body is displaced. Can be prevented.

The driving device for a bucket elevator of a continuous unloader according to the present invention is not limited to the above-described embodiment, and various changes can be made without departing from the scope of the present invention. It is.

[0014]

As described above, according to the bucket elevator driving device of the continuous unloader of the present invention, the alignment of the brake caliper with respect to the brake disc by the liner is unnecessary, and the displacement of the vibration-proof elastic body is eliminated. In this case, even when the brake force is generated, an excellent effect of preventing misalignment between the brake disc and the brake caliper can be obtained.
