Suspension arm rotary table on carrier vehicle

Abstract

The invention provides a suspension arm rotary table on a carrier vehicle and belongs to the technical field of coal mining equipment transportation. The suspension arm rotary table on the carrier vehicle aims to provide a rotary table for connecting a suspension arm with a vehicle body, wherein the rotary table can drive the suspension arm to rotate to a certain position under the condition that the vehicle body does not move, the operation difficulty is reduced, and the work safety is guaranteed. According to the technical scheme, a rotary plate support is fixedly mounted on a base through a bolt, an upper rotary plate is in an upturned disk-like shape and movably buckled on the rotary plate, matched grooves are formed in horizontal contact surfaces of the upper rotary plate and the rotary plate support, multiple first steel balls are arranged in the grooves, a middle movable rack is fixedly mounted in the middle of the bottom surface of the upper rotary plate and located in the rotary plate support, a gear ring is fixedly mounted on a circumferential side surface of the upper rotary plate, a hydraulic motor is fixedly mounted on one side of the rotary plate support through a motor support, and a gear meshed with the gear ring is fixedly mounted on an output shaft of the hydraulic motor. With the adoption of the suspension arm rotary table, work parts are more flexible relative to the vehicle body.

Description

technical field [0001] The boom turntable on the transport vehicle of the invention belongs to the technical field of coal mine equipment transport. Background technique [0002] Coal mine transportation is carried out in a relatively narrow roadway. In the case of changing installation positions, it is relatively difficult to operate the car body to turn or retreat in the driver's seat so that the objects on the boom reach the predetermined position, which increases the The labor intensity of the workers, and a lot of time wasted; the body of the car is relatively large, which may affect the work safety of the workers during the adjustment process. Contents of the invention [0003] The present invention overcomes the deficiencies in the prior art, and the technical problem to be solved is to provide a turntable for connecting the boom to the vehicle body, which drives the boom to rotate to a certain position when the vehicle body does not move, reducing the operating Di...
