Description

Technical Field

[0001] This utility model relates to the field of highway construction technology, and in particular to a hot rolling device for highway construction. Background Technology

[0002] Currently, asphalt pavement refers to various types of pavement constructed by mixing road asphalt materials with mineral materials. It is one of the most widely used high-grade pavement types in road construction. During the construction of asphalt pavement, it is often necessary to use a hot roller for asphalt road construction to compact the heated asphalt laid on the road, thereby achieving a smooth and durable pavement.

[0003] A search revealed a public announcement (CN214939015U) that discloses a hot rolling device for asphalt road construction. The device includes a base with multiple receiving slots on the ground side. Each of these slots contains a fixed shaft, and a roller body is rotatably mounted on the fixed shaft. The roller body is composed of a first half-cylinder and a second half-cylinder joined together. The device also includes a connector for connecting the first half-cylinder and the second half-cylinder. This application facilitates roller replacement.

[0004] In the aforementioned existing technical solutions, although the device provides a mechanism for disassembling the main body of the roller (such as fixing bolts and connecting bolts), since multiple connecting parts are involved, disassembly requires removing multiple bolts first and then removing multiple mounting blocks. This step is cumbersome, and the staff needs to spend a long time to complete these steps, which reduces work efficiency.

[0005] Therefore, we propose a hot rolling device for highway construction. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example: A hot rolling mill for highway construction, such as Figures 1-4As shown, the system includes a base 1, a traction ring 2 fixedly connected to one side of the base 1, three fixed shafts 4 at the bottom of the base 1, each with a limit groove 401 at both ends, a heating coil 301 wound on the fixed shaft 4 on the side of the fixed shaft 4 away from the traction ring 2 inside the base 1, a battery 3 fixedly mounted on the side wall of the base 1, one end of the heating coil 301 passing through the inner cavity of the fixed shaft 4 and electrically connected to the battery 3, half-cylinder 1 5 and half-cylinder 2 6 on both sides of the three fixed shafts 4, each with a slot 601 at the position corresponding to the limit groove 401, an insertion cavity 502 at the upper and lower walls of half-cylinder 1 5 near the side wall of half-cylinder 2 6, and an insertion block 7 fixedly connected at the position corresponding to the insertion cavity 502 on the wall of half-cylinder 2 6 near the wall of half-cylinder 1 5, each with a positioning hole 701. Positioning holes 501 are provided on both sides of the first half-cylinder 5 at positions that match the positioning holes 701. Fixing frames 8 are fixedly connected to both sides of the first half-cylinder 5 at positions corresponding to the positioning holes 501. Springs 801 are fixedly connected to the inner cavities of the fixing frames 8. Slots 802 that match the positioning holes 501 are provided on the wall of the fixing frames 8 near the first half-cylinder 5. A C-shaped connecting rod 9 is fixedly connected to the other end of the springs 801 on the same side. Insert rods 803 are fixedly connected to the wall of the fixing frames 8 near the first half-cylinder 5. Insert rods 803 match the slots 802 and the positioning holes 501. Limiting holes 902 are provided at the end of the bottom fixing frame 8 away from the insert rods 803. Limiting holes 901 are provided on the connecting rod 9 at positions that match the limiting holes 902. Limiting rods 903 are inserted into the inner cavities of the limiting holes 901 and the limiting holes 902.

[0026] The working principle of this utility model:

[0027] When it is necessary to disassemble and replace half-cylinder 1 5 and half-cylinder 2 6 during use, pull the connecting rod 9 on the same side. At this time, the spring 801 is compressed. The pulling of the connecting rod 9 causes the insertion rod 803 to be released from the positioning hole 2 701, moving half-cylinder 2 6 away from half-cylinder 1 5. At this time, the insertion block 7 is released from the inner cavity of the insertion cavity 502.

[0028] In use, the position of the connecting rod 9 is limited by inserting the limiting rod 903 into the inner cavity of the limiting hole 901 and the limiting hole 902, thereby limiting the position of the insert rod 803.
