Embodiment Construction

[0010] The present invention will be further described below in conjunction with the accompanying drawings.

[0011] As shown in the accompanying drawings, as shown in the accompanying drawings, the present invention consists of a main shaft 1, a slewing bearing 2, a connecting seat 3, a pin shaft I4, a lifting support 5, a pin shaft II6, a rotating seat 7, a bearing seat 8, an oil cylinder 9, Transmission device 10, key 11, hinge support 12, oil cylinder base 13 etc. are formed. The hinge support 12 is installed on the upper part of the lifting support 5, and the hinge support 12 is connected to the rotating seat 7 through the pin shaft II6; On the bearing blocks 8 on both sides.

[0012] The slewing bearing 2 is a transitional connection device, which can bear axial force, radial force and turning moment. The inner and outer rings can rotate relative to each other. The inner ring is connected to the main shaft 1, and the outer ring is connected to the oil cylinder 9 through...

Abstract

The invention discloses a rake lifting device of a center-drive concentrator automatically lifting a rake at a center. The existing device has a complex structure, is high-cost, has a long processingcycle, and has difficulty in lifting and lowering a main shaft. The device solves the above problem. The rake lifting device is characterized by further comprising a slewing bearing, a connection base, a rotating base, a bearing base, and a hinge support, wherein the hinge support is installed on the upper part of a lifting support, the hinge support is connected with the rotating base, the bearing base is installed at two sides of the upper plane of the rotating base, an oil cylinder body is installed on the bearing base, a piston rod of the oil cylinder is connected with an outer ring of theslewing bearing through the connection base, and the inner ring of the slewing bearing is connected with the main shaft. The slewing bearing which can bear an axial force, a radial force and a turning torque is adopted as a transition connection device, so that the structure is simplified, and the connection structure is more reliable; the rake lifting device uses fewer elements, has fewer faultpoints, has a shorter production cycle, has low processing and manufacturing cost, and is easy to maintain on site.

Description

technical field [0001] The invention relates to a rake lifting device of a concentrator, more precisely, relates to a rake lifting device of a central drive center automatic rake lifting concentrator. Background technique [0002] The central transmission center automatic rake-lifting concentrator is equipped with an automatic rake-lifting device, which realizes the lifting of the scraper rake through the lifting spindle. The lifting actuator of the rake lifting device is connected to the main shaft, and the main shaft rotates continuously during work. If the rake lifting device rotates with it, the power transmission of the rake lifting device will be very difficult. In order to provide power for the lifting actuator, the prior art generally installs a set of transitional connection devices at the end of the main shaft, and the lifting actuator is connected to the main shaft through the transitional connection device, so that the lifting actuator only moves. Planar thrust ...
