Hoisted cement pipe outer wall brushing device

Abstract

The invention relates to a hoisted cement pipe outer wall brushing device comprising a rotating shaft, a rotating plate rotating around the rotating shaft, transverse supports fixedly installed on the rotating plate, longitudinal supports connected with the transverse supports and brush heads located on the longitudinal supports. A hoisting plate is installed above the rotating shaft; a tray used for bearing a cement pipe is placed below the hoisting plate; the bottoms of the longitudinal supports are provided with walking wheels; the walking wheels walk along the outer side wall of the tray to enable the longitudinal supports to rotate around the rotating shaft; the longitudinal supports are provided with lifting devices; and the brush heads are fixedly installed on the lifting devices and move up and down along the longitudinal supports through the lifting devices. Furthermore, the walking tracks of the brush heads are limited, and the problem of unstable rotation amplitude is effectively avoided. The lifting devices are arranged on the longitudinal supports, the brush heads can move up and down only through lifting of the lifting devices, then the upper outer wall and the lower outer wall of the cement pipe are brushed, supporting facilities are reduced, the efficiency is improved, and meanwhile the cost is reduced.

Description

technical field [0001] The invention relates to a device for brushing the outer wall of a cement pipe for hoisting, and belongs to the field of prefabricated cement pipe fittings or component production equipment. Background technique [0002] The production of existing cement pipes requires the use of sand and cement. Therefore, there are different degrees of roughness on the outer surface of the cement components that cannot be formed, such as pores, depressions or pockmarks, which affect the use, service life and aesthetics. In order to solve this A technical problem, Chinese patent CN 110696169 A discloses a cement pipe brushing device, which drives the rotating device to lift through a fixed lifting device, and then rotates the brush head in the rotating device to polish the outer wall of the cement pipe by lifting and lowering. However, this technology has obvious limitations, which are manifested in: due to the large size of the cement pipe, the overall size of the de...

[0002] The production of existing cement pipes requires the use of sand and cement. Therefore, there are different degrees of roughness on the outer surface of the cement components that cannot be formed, such as pores, depressions or pockmarks, which affect the use, service life and aesthetics. In order to solve this A technical problem, Chinese patent CN 110696169 A discloses a cement pipe brushing device, which drives the rotating device to lift through a fixed lifting device, and then rotates the brush head in the rotating device to polish the outer wall of the cement pipe by lifting and lowering. However, this technology has obvious limitations, which are manifested in: due to the large size of the cement pipe, the overall size of the device is large and cannot be moved, and the cement pipe needs to be passed through a forklift during use. or the crane moves under the swivel, resulting in inefficiencies
