Description

Technical Field

[0001] The utility model relates to the technical field of asphalt pavement leveling, in particular to a leveling device for asphalt pavement construction. Background Art

[0002] In asphalt pavement construction, high-temperature molten asphalt is generally spread on the road surface through paving equipment. The raw materials are a mixture of mineral materials and asphalt materials. The asphalt binder improves the ability of paving aggregate to resist damage to the road surface caused by traffic and natural factors, making the road surface smooth, dust-free, waterproof and durable. In asphalt pavement construction, the asphalt raw materials need to be placed on the road surface. In order to increase the compaction and flatness of the asphalt pavement, it is often necessary to use rollers or leveling devices to reciprocately roll and level the paved asphalt pavement so that the paved asphalt pavement has sufficient compaction and flatness.

[0003] In order to improve the shaping effect when paving asphalt, its temperature is generally high and it has high viscosity, which causes the leveling roller of the leveling device to stick to the asphalt during the reciprocating rolling process. If the sticky asphalt is not cleaned in time, it will quickly cool and solidify on the side wall of the leveling roller, thereby affecting the smoothness of the surface of the leveling roller and reducing the leveling effect of the road surface; and in the actual leveling process, the newly paved asphalt road surface will often drop branches, fallen leaves and other debris. If they are not cleaned before leveling, they will be rolled into the asphalt road surface by the leveling roller, affecting the appearance and flatness of the asphalt road surface.

[0004] Therefore, it is necessary to invent a leveling device for asphalt pavement construction to solve the above problems. Utility Model Content

[0005] In order to address the deficiencies in the prior art, the purpose of the utility model is to provide a leveling device for asphalt pavement construction, which solves the problem that the leveling roller of the leveling device in the prior art will stick to asphalt during the reciprocating rolling process, and if the sticky asphalt is not cleaned in time, it will quickly cool and solidify on the side wall of the leveling roller, thereby affecting the smoothness of the surface of the leveling roller and reducing the leveling effect on the road surface; and in the actual leveling process, the newly paved asphalt road surface will often drop debris such as branches or fallen leaves. If they are not cleaned before leveling, they will be rolled into the asphalt road surface by the leveling roller, affecting the appearance and flatness of the asphalt road surface.

[0006] In order to achieve the above objectives, the utility model adopts the following technical solutions:

[0007] A leveling device for asphalt pavement construction, comprising a middle plate that can move along the asphalt pavement from right to left and two side frames that can be detachably installed at the left and right ends of the middle plate, each of the side frames having a leveling roller that can be detachably and rotatably installed for leveling the asphalt pavement, both left and right ends of the middle plate having an arc-shaped scraper that abuts against the peripheral side walls of the leveling roller, a front collecting frame is installed at the left end of the side frame located on the left side, a front collecting trough is provided on the left side of the front collecting frame, a front shovel plate is detachably installed at the left end of the front collecting frame, and a rotating roller is rotatably installed at the top end of the front shovel plate, and a symmetrical position of each front collecting trough is adapted to rotate, and the spacing between the two rotating rollers at the symmetrical position of the same front collecting trough is greater than the spacing between the two adjacent rotating rollers of the two adjacent front collecting troughs, and a rear end collecting component that can collect the asphalt scraped off by the arc-shaped scraper is detachably installed on the right side of the side frame located on the right side.

[0008] As a preferred solution of the utility model, the rear end collection assembly includes a rear collection rack detachably mounted on the right side of the side frame, a plurality of rear collection troughs opened on the left end of the rear collection rack, and a rear shovel plate mounted on the left end of the rear collection rack.

[0009] As a preferred solution of the utility model, the two ends of the rear collecting rack are detachably connected to the two ends of the side frame through connecting plates.

[0010] As a preferred solution of the utility model, a column is detachably connected to each roller position at the top end of the front shovel plate, and multiple rollers are detachably rotatably sleeved on corresponding columns. Side guide plates are detachably installed on both sides of the front shovel plate, and the positions of the two side guide plates are respectively adapted to the two sidemost roller positions.

[0011] As a preferred solution of the utility model, a plurality of connecting rods are provided on a side of the arc-shaped scraper away from the corresponding leveling roller, and the other ends of the plurality of connecting rods are detachably connected to the end surface of the middle plate.

[0012] As a preferred solution of the utility model, the bottom end of the front shovel plate and the bottom end of the rear shovel plate are both flush with the bottom arc surface of the leveling roller.

[0013] In the above technical solution, the technical effects and advantages provided by the utility model are:

[0014] In the utility model, when the leveling device moves from right to left along the newly paved asphalt road surface, the front shovel plate at the left end of the side frame on the left side of the middle plate can shovel up debris such as branches or leaves that have fallen on the asphalt road surface. Some smaller debris can enter the front collecting trough through the gap between the rollers for centralized collection, while some smaller debris or debris with larger shapes gradually move to both sides under the rotation of the rollers until they leave the asphalt road surface from both sides. In the actual leveling process, the asphalt road surface is repeatedly reciprocated and rolled by the two leveling rollers. In the rolling process, the two arc-shaped scrapers respectively scrape the sticky asphalt on the side walls of the corresponding leveling rollers uninterruptedly. The sticky asphalt is prevented from cooling down quickly and solidifying on the side wall of the leveling roller, which may affect the surface smoothness of the leveling roller, thereby improving the leveling effect of the road. Part of the scraped sticky asphalt is further rolled into the asphalt road surface by the right leveling roller, while part of the scraped sticky asphalt is collected in the rear collecting trough under the shoveling action of the rear shovel plate, ultimately ensuring that the fallen branches or leaves are effectively removed from the asphalt section passed by the leveling device, and at the same time, the sticky asphalt on the side wall of the leveling roller is continuously scraped off, and the sticky asphalt that is scraped off but not rolled onto the road surface is collected, ultimately ensuring that the asphalt road surface is free of debris and the appearance and smoothness of the asphalt road surface are improved.

[0023] The two ends of the rear collecting frame 12 are detachably connected to the two ends of the side frame 2 through connecting plates 15 respectively.

[0024] A column 9 is detachably connected to the top of the front shovel plate 8 and each roller 10 is adapted to be positioned.
