Description

Camber adjusting device for screed of paver

Technical Field

The utility model relates to the technical field of road pavement construction equipment, in particular to a camber adjusting device for a screed of a paver.

Background

The paver is a construction equipment mainly used for paving various materials on the base layer and the surface layer of the highway. The screed is a main working component of the paver and mainly used for leveling, shaping and pre-compacting the pavement paving materials conveyed by the spiral distributor so as to provide good working conditions for further compaction of a subsequent road roller. In order to ensure the road surface drainage function, the paver needs the screed plate to adjust the camber when performing the road surface paving operation, so as to meet the construction requirements of different road surface camber. The camber adjustment of the screed of the paver in the prior art adopts a hydraulic adjusting mechanism or a worm and gear adjusting mechanism, and the adjusting mechanism is complex, high in configuration cost and poor in durability.

Disclosure of Invention

The utility model aims to solve the problems and provides the camber adjusting device of the screed of the paver, which is convenient to operate, can meet the camber design requirements of different pavements, and has the advantages of simple structure, low configuration cost and good durability.

The technical scheme for realizing the purpose is as follows: the utility model provides a paver screed camber adjusting device, includes a pair of screed of hinge connection through pivot bilateral symmetry the front and back both ends of screed are equipped with a pair of end plate of erectting, the lower part of both ends plate respectively with the pivot hinge connect the upper portion bilateral symmetry of both ends plate sets up a pair of longitudinal tie plate, the central point of two longitudinal tie plates puts and is equipped with horizontal regulation pole, the both ends coaxial line of adjusting the pole assembles the screw rod that revolves to opposite respectively, the outside end of two screw rods respectively with a pair of longitudinal tie rod fixed connection that bilateral symmetry set up, a pull rod is connected in the hinge respectively at the both ends of two longitudinal tie rods, the lower extreme of four pull rods is in with the setting four ear seat hinge connections above a pair of screed respectively.

According to the camber adjusting device for the screed of the paver, the adjusting rod is assembled on the longitudinal connecting plate through the pair of bearings which are symmetrically arranged left and right.

When the leveling device works, the adjusting rod is rotated, so that the screws which are coaxially assembled at the two ends of the adjusting rod and have opposite rotation directions synchronously extend and retract, and the pair of the screed plates are driven to rotate by the longitudinal connecting rod and the hinged pull rod by taking the rotating shaft as the center, so that the camber adjustment of the screed plates during the construction operation of the paver is realized. The road surface camber angle adjusting device is convenient to operate, can meet the camber construction requirements of different road surfaces, and has the characteristics of simple structure, low configuration cost and good durability.

Detailed Description

The following describes embodiments of the present invention with reference to the drawings.

The device for adjusting the camber of the screed of the paver shown in fig. 1 and 2 comprises a pair of screeds 2 which are symmetrically hinged left and right through a horizontally arranged longitudinal rotating shaft 1, wherein in the embodiment shown in fig. 2, the two screeds 2 are hinged with the rotating shaft 1 through a pair of connecting lug plates respectively arranged at the inner side ends of the two screeds. A pair of vertically arranged end plates 3 are respectively arranged at the front end and the rear end of the ironing plate 2 which is hinged, the lower parts of the two end plates 3 are hinged with the rotating shaft 1 through respectively arranged shaft holes, and as shown in the embodiment of the attached drawing, the rotating shaft 1 can adopt a bolt type shaft. A pair of longitudinal connecting plates 4 is symmetrically arranged on the left and right of the upper parts of the two end plates 3, and the two longitudinal connecting plates 4 and the two end plates 3 can form a rectangular frame structure by welding. The central positions of the two longitudinal connecting plates 4 are provided with adjusting rods 5 which are transversely arranged, and the adjusting rods 5 are symmetrically provided with shaft shoulders for assembling and positioning the adjusting rods with the two longitudinal connecting plates 4. The two ends of the adjusting rod 5 are respectively provided with a screw rod 6 with opposite turning directions through the coaxial line of the arranged internal thread holes, the outer side ends of the two screw rods 6 are respectively fixedly connected with a pair of longitudinal connecting rods 7 which are arranged in bilateral symmetry through welding, and the longitudinal connecting rods 7 of the embodiment of the attached drawing adopt square steel pipes with end sealing plates at the two ends. Two ends of the two longitudinal connecting rods 7 are respectively connected with a pull rod 8 which inclines outwards through ear seat hinges, and the lower ends of the four pull rods 8 are respectively hinged with four ear seats 9 arranged on the pair of ironing plates 2. In the embodiment of the drawing, the hinge shaft of the upper and lower ends of the tie rod 8 is a bolt type hinge shaft.

According to the camber adjusting device for the screed of the paver, the adjusting rod 5 is assembled on the longitudinal connecting plate 4 through the pair of bearings 10 which are symmetrically arranged left and right, so that the rotating resistance of the adjusting rod 5 is reduced, and the assembling stability of the adjusting rod 5 is improved. The two bearings 10 are respectively fixed on the outer side surfaces of the two longitudinal connecting plates 4 through bolt connection. The bearing 10 shown in the embodiment of the drawings is a plain bearing. The bearing 10 may be a rolling bearing.
