Problems solved by technology

The spiral extension section and the screed extension section range from hundreds of kilograms to thousands of kilograms. As the road construction progresses, the paving width will continue to change with the needs of the construction party. Although there are retractable screeds to a certain extent It meets the requirements of different paving widths, but the matching spiral extensions still need to be spliced. If different paving widths need to be spliced, it is quite difficult to lift and install it all by manpower on a construction site without special lifting auxiliary equipment such as forklifts. And it is time-consuming and labor-intensive, and the work efficiency is low, which seriously affects the construction efficiency and construction progress of the paver

Embodiment Construction

[0030] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments, but not as a limitation of the present invention.

[0031] Such as figure 1 and figure 2 As shown, the present invention discloses a lifting device, which is arranged on the outside of the frame 4 of the paver for lifting the spiral extension section 5 and the screed extension section 6 of the paver.

[0032] continue to combine figure 1 and figure 2 , the lifting device includes: a first telescopic mechanism 1 , a second telescopic mechanism 2 and a third telescopic mechanism 3 . The first telescoping mechanism 1 is provided with a hoisting connector for hooking connection with the helical extension section 5 and the screed extension section 6 to be hoisted. The second telescopic mechanism 2 and the third telescopic mechanism 3 are hinged with the first telescopic mechanism 1 respectively, and are used to control and adjust the s...

Abstract

The invention discloses a lifting device and a paver with the lifting device. The lifting device comprises a first telescoping mechanism, a second telescoping mechanism and a third telescoping mechanism, wherein one end of the first telescoping mechanism is hinged to a rack to form a first hinge point, and a lifting connecting piece is arranged on the first telescoping mechanism; one end of the second telescoping mechanism is hinged to the rack to form a second hinge point, and the other end of the second telescoping mechanism is hinged to the other end of the first telescoping mechanism; one end of the third telescoping mechanism is hinged to the rack to form a third hinge point, and the other end of the third telescoping mechanism is hinged to the position, close to the other end of the third telescoping mechanism, of the first telescoping mechanism; the first hinge point, the second hinge point and the third hinge point are not in the same line, and the second hinge point is located above the first hinge point. The lifting device can be used for quickly lifting a spiral extending section and a screed plate extending section within the full paving width of the paver, lifting is convenient and fast, and saves time and labor are saved. The paver with the lifting device can be used for quickly lifting the spiral extending section and the screed plate extending section independently on a construction site without a forklift and other auxiliary lifting equipment.

Description

technical field [0001] The invention relates to a quick hoisting device for a paver spiral extension section and a screed extension section and a paver with the hoisting device. The utility model belongs to the field of road construction machinery. Background technique [0002] Paver is a common equipment for road construction, which is mainly used for paving various materials on the road base and surface. The screw distributor and the screed are important parts of the paver. The screw distributor is a key part of the material flow during the construction of the paver. Its main function is to transfer the material to be paved from the middle to the two sides. The channel is a material trough composed of a screw retaining plate and a screed. The screed is a main working part of the paver. Carry out leveling, shaping and pre-compaction to provide good working conditions for the subsequent further compaction of the road roller. [0003] With the continuous development of sci...
