Problems solved by technology

The asphalt spreading device of this structure is only suitable for asphalt paver for high-speed paving. Covering the paving width of the screed, the length of the asphalt spreading device is equivalent to the length of the screed. When paving a wide road surface, the length of the asphalt spreading device is very long, and multiple nozzles must be installed on the mounting frame at the same time. The structure complex and expensive

Embodiment 1

[0032] Such as figure 1 and figure 2 As shown, the mobile asphalt spreading device of this embodiment includes a guide rail mounting plate 1, a guide rail 2, an asphalt nozzle 3, a fixed square pipe 4, a fixed plate 5 and a mobile control component. For the convenience of description, the direction parallel to the guide rail 2 is defined as the transverse direction. The asphalt nozzle 3 of the present embodiment is installed on the fixed square pipe 4 at equidistant intervals, and the middle part of the fixed square pipe 4 is provided with two fixed plates 5 at intervals. Figure) is connected, is used for spraying asphalt or other emulsifiers to the ground, and the asphalt nozzle 3 of the present invention is identical in structure with the asphalt nozzle of the prior art. The fixed square tube 4 and the fixed plate 5 constitute the nozzle mounting frame of this embodiment, and the nozzle mounting frame can also adopt other forms, such as replacing the fixed plate 5 with a ...

Embodiment 2

[0035] Such as Figure 5 and Figure 6As shown, the difference between this embodiment and Embodiment 1 is that two guide rails 2 are installed between the lower parts of the two guide rail mounting plates 1, and the fixing plate 5 is installed on the two guide rails 2 and moves laterally along the guide rails 2. The fixed square tube 4 is affixed to the bottom of the fixed plate 5 and is located below the guide rail 2. A corresponding pulley 9 is installed on the opposite inner wall of the two guide rail mounting plates 1, and one of the pulleys 9 is mounted on the guide rail. The drive motor 8 on the plate 1 drives, and the steel rope 10 walks around two pulleys 9, and a certain point on the steel rope 10 is tightened and fixedly connected to the top of the fixed plate 5 with bolts. When the drive motor 8 drives the pulley 9 to rotate, the pulley 9 drives the steel rope 10 to move, and the steel rope 10 pulls the fixed plate 5 to move on the guide rail 2, so that the nozzle...

Embodiment 3

[0037] Such as Figure 7 and Figure 8 As shown, the difference between this embodiment and Embodiment 1 is that a rack 11 parallel to the guide rail 2 is installed between the two guide rail mounting plates 1, and the transverse length of the rack 11 is greater than that between the two guide rail mounting plates 1. The two ends of the rack 11 pass through the guide rail mounting plate 1, so that the rack 11 is supported on the guide rail mounting plate 1 when the rack 11 moves laterally in a direction parallel to the guide rail 2, and the rack 11 is fixed with Two fixed plates 5 arranged at intervals are fixed with a driving motor 8 through a mounting bracket 20 at the midpoint of the guide rail 2, and a driving gear 80 meshing with the rack 11 is installed on the output shaft of the driving motor 8. When the driving motor 8 drives When the driving gear 80 rotates, the rack 11 meshing with the driving gear 80 moves leftward or rightward with the rotation of the driving gear...

Abstract

The invention relates to a movable asphalt spreading device. The device comprises asphalt nozzles arranged on a nozzle installation frame at intervals, wherein the nozzle installation frame is arranged on a guide rail; the guide rail is arranged on a guide rail installation frame; and a movable control component for driving the nozzle installation frame to move along the guide rail is arranged between the nozzle installation frame and the guide rail installation frame. A transversely-moving asphalt spreading device has the advantages of small occupied space and simple and compact structure. Asphalt can be sprayed on a road surface to be paved when the nozzle installation frame moves transversely along the guide rail, so that automation degree is high. The nozzles spray in a single travel of forward and backward movement of the nozzle frame, so that non-uniformity easily caused by uninterrupted asphalt spraying of the nozzles when a paver paves at a low speed is avoided, so that paving quality is improved.

Description

technical field [0001] The invention belongs to the field of road construction machinery, in particular to a laterally movable asphalt spreading device and an asphalt paver equipped with a mobile asphalt spreading device. Background technique [0002] Asphalt pavement is a pavement structure in which a certain thickness of asphalt mixture is paved on a flexible base or a semi-rigid base. Compared with gravel pavement, this kind of pavement has greatly improved driving comfort, safety and strength stability. Compared with cement concrete pavement, asphalt pavement has a smooth surface without joints, small driving vibration, low noise, and fast construction. Short construction period, fast open traffic, easy maintenance, suitable for phased construction of pavement, is an important structural form of pavement in our country. [0003] When building asphalt-stabilized soil pavements or pavement bases, asphalt distributors are often used to supply asphalt binders, such as liqui...
