Abstract
Description
Technical Field
[0001] This utility model relates to the field of rolling devices, specifically a municipal road and bridge rolling device. Background Technology
[0002] As is well known, municipal road and bridge compaction rollers are equipment used in road and bridge construction, mainly for compacting road surfaces to ensure a smooth and firm surface after construction. These devices typically consist of a roller and a power mechanism. As the roller rotates, the power mechanism drives a scraper to reciprocate across the roller surface, removing any adhering materials and ensuring the roller maintains a consistently good compaction effect. This design not only improves work efficiency but also reduces maintenance costs.
[0003] However, most existing municipal road and bridge rolling devices on the market use rollers to roll municipal road and bridge surfaces. When the rollers are used to roll the road surface, solid impurities such as stones often adhere to the surface of the rollers. The rollers in the rolling devices do not have an automatic cleaning mechanism, which can lead to unevenness and damage to the road surface. Utility Model Content
[0004] (a) Technical problems to be solved
[0005] To address the shortcomings of existing technologies, this utility model provides a municipal road and bridge rolling device. This device features advantages such as preventing the adhesion of solid impurities like stones to the surface of the rolling rollers during rolling operations, and ensuring that the rolling rollers have an automatic cleaning mechanism, thus preventing unevenness and damage to the road surface. This solves the problem of solid impurities like stones adhering to the surface of the rolling rollers during municipal road and bridge rolling operations, and the lack of an automatic cleaning mechanism in the rolling rollers, which leads to unevenness and damage to the road surface.
[0006] (II) Technical Solution
[0007] To achieve the goal of preventing the adhesion of solid impurities such as stones to the surface of the rolling rollers during the compaction of municipal roads and bridges, and to ensure that the rolling rollers in the compaction device have an automatic cleaning mechanism, thus avoiding unevenness and damage to the road surface, this utility model provides the following technical solution: A municipal road and bridge compaction device, comprising a frame and a pressure roller. The inner wall of the frame has a first slide rail, and a first spring is fixedly connected to the inner wall of the first slide rail. A slider is fixedly connected to one end of the first spring, and a scraper is fixedly connected to one side of the slider. A collection frame is fixedly connected to the outer wall of the scraper. A first bearing is embedded in one side of the pressure roller, and a first connecting roller is fixedly connected to the inner ring of the first bearing. The inner wall of the frame has a second groove. A cylinder is fixedly connected to the inner wall of the second chute. A piston rod is provided at one end of the cylinder, and a first buffer rod is fixedly connected to one end of the piston rod. A second spring is fixedly connected to one end of the first buffer rod, and a first buffer rod is fixedly connected to one end of the second spring. When the pressing roller rotates on the ground, it can press the ground. Since the outer wall of the scraper is slidably connected to the outer wall of the pressing roller, when the pressing roller rotates, one side of the scraper will scrape the material on the outer wall of the pressing roller. Thus, when the pressing roller is used for rolling operations on municipal road and bridge pavements, the surface of the pressing roller is often free of solid impurities such as stones. The pressing roller in the rolling device has an automatic cleaning mechanism, which prevents the road surface from becoming uneven or damaged, thereby improving the rolling effect of the device.
[0008] As a preferred embodiment of this utility model, the outer wall of the slider is slidably connected to the inner wall of the first slide, and the outer wall of the scraper is slidably connected to the outer wall of the pressing roller. When the pressing roller rotates on the ground, it can press the ground.
[0009] As a preferred embodiment of this utility model, the outer wall of the first connecting roller is slidably connected to the inner wall of the second sliding groove, and the outer wall of the second buffer rod is fixedly connected to the outer wall of the first connecting roller. The first connecting roller can play a supporting role, and the second buffer rod can buffer the pressure roller through the second spring.
[0010] As a preferred embodiment of this utility model, a second bearing is embedded on one side of the pressing roller, and a second connecting roller is fixedly connected to the inner ring of the second bearing. The second connecting roller can support the pressing roller.
[0011] As a preferred embodiment of this utility model, the inner sidewall of the frame is provided with a first sliding groove, the outer wall of the second connecting roller is slidably connected to the inner wall of the first sliding groove, a first lifting rod is fixedly connected to the inner wall of the first sliding groove, and a third spring is fixedly connected to the bottom of the first lifting rod. The third spring can buffer the second connecting roller through the first lifting rod, thereby providing an auxiliary buffering effect for the pressing roller.
[0012] In a preferred embodiment of this invention, one end of the third spring is fixedly connected to the second lifting rod, and one end of the second lifting rod is fixedly connected to the outer wall of the second connecting roller. The second lifting rod can buffer the second connecting roller through the third spring.

[0015] Beneficial effects:
[0016] 1. When the pressing roller rotates on the ground, it can press the ground. Since the outer wall of the scraper is slidably connected to the outer wall of the pressing roller, when the pressing roller rotates, one side of the scraper will scrape the material on the outer wall of the pressing roller. Thus, when the pressing roller is used for rolling operations on municipal road and bridge pavement, the surface of the pressing roller is usually free of solid impurities such as stones. The pressing roller in the rolling device has an automatic cleaning mechanism, which will not cause unevenness or damage to the road surface, thereby improving the rolling effect of the device.
