Description

Technical Field

[0001] This utility model relates to the field of road construction technology, specifically to a joint treatment device for road construction. Background Technology

[0002] In the field of road construction, joints refer to structural measures installed on the road surface to cope with temperature changes, humidity shrinkage, and construction requirements.

[0003] Nowadays, in order to deal with road surface gaps that occur during road construction, workers will take various measures to treat the gaps, such as using an edge cutter to cut the edges of the road surface gaps, or injecting asphalt into the gaps to reduce the impact of the gaps on the road surface.

[0004] However, during asphalt pavement construction, paving operations are often interrupted due to equipment malfunctions, weather changes (such as sudden heavy rain), or traffic control. By the time construction resumes, the paved asphalt mixture has cooled, resulting in cold joints between pavements constructed at different times. When re-laying the pavement or injecting asphalt into the joints, the significant temperature difference between the injected asphalt and the cold joint leads to poor adhesion at the joint, resulting in water seepage, loosening, and cracking, thus affecting the pavement's performance and lifespan. Therefore, we propose a joint treatment device for road construction to effectively address these problems. Utility Model Content

Detailed Implementation

[0021] 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.

[0022] Please see Figure 1 - Figure 5 A joint treatment device for road construction includes a body 1 with a hollow internal structure. A first motor 101 is fixedly installed inside the body 1. The output shaft of the first motor 101 extends to the outside of the body 1 and is fixedly mounted on a switching plate 2. The output shaft of the first motor 101 is distributed along the left-right direction of the body 1. The output shaft of the first motor 101 is rotatably connected to the side wall of the body 1 via a rotating bearing. The output shaft of the first motor 101 is fixedly connected to the switching plate 2 via a connecting bearing. Therefore, the first motor 101 can control the switching plate 2 to rotate around the output shaft.

[0023] Furthermore, a trimming mechanism 3 is provided at one end of the switching plate 2. A support plate 201 is fixedly mounted on the side of the switching plate 2 away from the machine body 1. A cylinder 202 is fixedly mounted on the support plate 201 along the length of the switching plate 2. The cylinder 202 drives the trimming mechanism 3 to move along the length of the switching plate 2. This allows the cylinder 202 to control the extension or retraction of the trimming mechanism 3, thereby changing the cutting depth of the trimming mechanism 3 and adapting to slits of greater depth.

[0024] Specifically, the edge-cutting mechanism 3 includes a movable plate 301 that is telescopically connected to the switching plate 2 along its length. A connecting plate 302 is fixedly mounted on the side of the movable plate 301. The connecting plate 302 is fixedly connected to the movable end of the cylinder 202. A second motor 303 is mounted on the connecting plate 302. The output shaft of the second motor 303 passes through the movable plate 301 and is coaxially connected to a cutting disc 304. The cutting disc 304 has a diameter of 390 mm and is used to cut the edge of asphalt. The cylinder 202 can control the movement of the connecting plate 302 and the movable plate 301, thereby driving the second motor 303 and the cutting disc 304 to move, thus changing the cutting depth of the cutting disc 304.

[0025] The output shaft of the second motor 303 is distributed in the left-right direction, and the output shaft of the second motor 303 is rotatably connected to the moving plate 301 through a rotating bearing. The output shaft of the second motor 303 is fixedly connected to the cutting disk 304 through a connecting bearing. Therefore, the second motor 303 can control the cutting disk 304 to rotate around the output shaft.

[0026] In this embodiment, a heater 4 is provided at the end of the switching plate 2 away from the edge-cutting mechanism 3, so that the edge-cutting mechanism 3 and the heater 4 can be switched by the rotation of the switching plate 2.

[0027] Specifically, the heater 4 is rotatably connected to the connecting part 203 via a rotating shaft 401. The rotating shaft 401 passes through the connecting part 203 along the width direction of the switching plate 2, and both ends of the rotating shaft 401 are fixedly provided with rotating handles 402. Therefore, the heater 4 can rotate around the rotating shaft 401 in the left-right direction. The bottom of the heater 4 has a flame nozzle, so that the orientation of the flame nozzle can be changed when the heater 4 swings, thereby adapting to the joint treatment operation of road surfaces with different slopes.

[0028] The heater 4 is equipped with 6 heating chambers. It is heated by liquefied gas and heated in stages. The heating temperature is basically controlled between 140-160 degrees Celsius. The flame temperature can be adjusted by the size of the liquefied gas valve to achieve the ideal heating temperature, turning cold joints into hot joints and greatly improving the construction quality and convenience.

[0029] Furthermore, a fixing bolt 403 is slidably provided on the rotating handle 402 along the front-back direction. A plurality of limiting holes 204 are provided on the side of the connecting part 203 facing the fixing bolt 403, and these limiting holes 204 are arranged circumferentially around the rotating shaft 401. The limiting holes 204 are used for inserting the fixing bolt 403. When the fixing bolt 403 disengages from the limiting hole 204, rotating the handle 402 can change the tilt angle of the heater 4; when the fixing bolt 403 is inserted into the limiting hole 204, rotating the handle 402 is fixed, thus fixing the heater 4.

[0030] like Figure 1 As shown, two protective mechanisms 5 are fixedly installed on the side of the machine body 1 facing the switching plate 2. When the switching plate 2 is rotated to a horizontal position, the two protective mechanisms 5 are used to block the cutting mechanism 3 and the heater 4, respectively. Figure 5 As shown, the protective mechanism 5 includes a baffle 501 fixedly connected to the side of the body 1. The baffle 501 is L-shaped. The protective mechanism 5 also includes a cover plate 502 slidably connected to the side wall of the body 1 in the left-right direction. The cover plate 502 is U-shaped and located inside the baffle 501. When the cover plate 502 slides to... Figure 5In the indicated state, baffle 501 and cover 502 can abut against each other to enclose the trimming mechanism 3 or heater 4. This allows the trimming mechanism 3 and heater 4 to be shielded and protected when not in use, reducing the impact of dust and other impurities on the device and preventing injuries caused by operator error.

[0031] The primary application scenario of this embodiment is during the asphalt pavement paving process. Workers first spread asphalt and other materials on the ground to form a road area. As the asphalt solidifies, unevenness may occur on both sides of the road surface due to the flow of the asphalt during solidification or the presence of air bubbles in the asphalt material. In this case, the edge trimming mechanism 3 is needed to smooth the road edges. On the other hand, during construction, unexpected events such as rain may occur, causing construction to stop. By the time construction resumes, the paved road surface has cooled and solidified. Laying another pavement next to this solidified pavement will result in a temperature difference between the two, creating a cold joint. If hotter asphalt is directly poured into this cold joint, the significant temperature difference between the poured asphalt and the pavement at the cold joint will lead to poor adhesion at the joint, resulting in water seepage, loosening, cracking, and other defects, affecting the pavement's performance and lifespan. At this point, heater 4 is needed to heat the cold joint, turning it into a hot joint, thereby improving the bonding degree with the asphalt material and improving the quality of the constructed road.

[0032] The specific operation method of this embodiment is as follows: When it is necessary to flatten the road edge, the vehicle body can be pushed by electric control or manual. At this time, the cutting mechanism 3 faces the lower part of the machine body 1. The height of the cutting disc 304 is adjusted by the cylinder 202 so that the cutting disc 304 contacts the road edge. The cutting disc 304 is driven to rotate by the second motor 303 to trim the road edge.

[0033] When cold joints need to be treated, the vehicle body is moved via electronic or manual control. The first motor 101 controls the switching plate 2 to rotate 180°, moving the cutting mechanism 3 to a position closer to the top of the machine body 1, while the heater 4 moves closer to the bottom of the machine body 1. Then, the handle 402 is used to rotate the flame-emitting end of the heater 4 towards the cold joint, controlling the heater 4 to start igniting and heating the cold joint, melting the solidified asphalt. Following this, the asphalt to be injected into the cold joint is poured in, thus treating the gap between the two road surfaces.
