Waste paper recovery pretreatment device

Abstract

The invention relates to the technical field of building production, and discloses a waste paper recovery pretreatment device. The waste paper recovery pretreatment device comprises a crane boom; a storage sleeve is hinged to the bottom of the left end of the crane boom, and the bottom ends of the front inner wall and the rear inner wall of the storage sleeve are both provided with skewed slots, and the left ends of the interiors of the skewed slots are fixedly connected with first telescopic rods; one ends of the first telescopic rods are fixedly connected with supporting arms, and the two opposite surfaces of the two supporting arms are fixedly connected with the front end and the rear end of a transverse rod correspondingly, and a user can conveniently hang a lifting hook on the transverse rod; the storage sleeve is rotated by 90 degrees under pull force of a second telescopic rod and connected to the bottom of the outer wall of the crane arm in a sleeving mode, so that a driver hasa wide visual field to observe the road condition, and in addition, the situation that normal running of surrounding vehicles is influenced by the lifting hook is avoided; when the vehicle is drivenon an uneven road surface, the lifting hook is clamped in the middle by two baffles and buffer springs, thus, the lifting hook is conveniently limited, the left-right swing amplitude of the lifting hook is reduced, and the situation that the running stationarity of the vehicle is influenced by large-amplitude left-right swing is avoided.

Description

technical field [0001] The invention relates to the technical field of waste paper recycling and processing equipment, in particular to a waste paper recycling pretreatment device. Background technique [0002] In the construction industry, in order to lift some heavy building materials, cranes are needed. Among them, truck cranes are widely used because of their good mobility. In order to adapt to different lifting weights and heights, they are divided into small, medium, large and Super large truck crane. [0003] In the existing technology, when the hooks of most truck cranes are retracted, they will be hung in front of the driver's cab, which will easily block the driver's part of the line of sight when driving. The hooks of most truck cranes are tied to the bumper of the front of the car with canvas belts or steel wires. When driving on the road, it is easy to affect the normal driving of surrounding vehicles. Contents of the invention [0004] The object of the pre...
