Description

Technical Field

[0001] The utility model relates to the technical field of coil paving, in particular to a paving device for a plastic running track, stadium and fitness trail of an EVA prefabricated coil. Background Art

[0002] With the rapid development of the sports industry and people's pursuit of a healthy life, the demand for the construction of sports venues such as plastic tracks, stadiums and fitness trails is growing. Among them, ethylene-vinyl acetate copolymer (EVA) is widely used in the manufacture of prefabricated coils due to its excellent elasticity, wear resistance and environmental protection performance, especially in the construction of plastic tracks, stadiums and fitness trails.

[0003] The existing waterproofing membrane laying process is mostly manual laying. The waterproofing membrane is prepared, opened and straightened, and laid on the bottom plate and top plate of the main body of the tunnel. The overlap width is corrected, the overlap edge plastic film is peeled off, pasted, and rolled with a roller. Although this method of laying the membrane can achieve a good waterproof effect, the manual laying efficiency is too low and the construction cost is high. The waterproofing and anti-seepage effect of the waterproofing membrane also depends on the technical level of the waterproofing worker. The waterproofing membrane laid by unskilled operators often has a poor waterproofing effect.

This utility model is a self-adhesive waterproof membrane laying device and method. When the self-adhesive waterproof membrane is spread, the semi-automatic laying of the self-adhesive waterproof membrane can be realized, and it can be completed in one time. It can realize the enhanced compression of the self-adhesive edge of the membrane, and can realize the collection of the plastic film of the self-adhesive edge, thereby improving the construction efficiency, improving the construction quality and saving energy and environmental protection.

[0005] In view of the above problems, the existing patents provide solutions, but there is a problem that the adhesive surface of the coil cannot be heated before laying to improve the flatness and adhesion of the coil.

At the same time, the coil cannot be heated, and the adhesion of the coil itself cannot be fully exerted.

[0006] Therefore, a paving device for a plastic running track, court and fitness trail of EVA prefabricated coil is proposed. Utility Model Content

[0017] Compared with the prior art, the beneficial effects of the utility model are:

[0018] 1. The present application is provided with a coil heating mechanism.

After the EVA coil is preheated by burning, its surface temperature will increase, so that some protective films or coatings on its surface are easier to remove, exposing a substrate that is more conducive to bonding. The temperature difference between the preheated coil and the base layer (such as cement mortar, etc.) is reduced, which helps to improve the bonding strength between the two and ensure that the coil can be firmly laid on the base layer. Preheating helps the coil to unfold more evenly and reduce deformation or wrinkling caused by uneven temperature, thereby improving the flatness after laying. By providing a coil heating mechanism, the coil can be heated before laying, thereby improving the bonding effect between the coil and the ground and ensuring the flatness and durability of the runway, stadium and fitness trail.

[0019] 2. The present application is provided with a ground cleaning mechanism. Before the coil of material is laid, the ground cleaning mechanism starts working. By operating the movable rod, the cleaning plate descends, and the brush bar contacts the ground to clean the ground. At the same time, the supporting spring plays a buffering role to ensure that there is appropriate pressure between the cleaning plate and the ground, thereby improving the cleaning effect. The dust and debris generated by cleaning are collected by the dust removal component. After the vacuum cleaner is started, the dust is sucked into the vacuum cleaner through the dust suction pipe and the dust suction head. The ground cleaning mechanism can effectively remove dust, debris, etc. on the ground, provide a clean base surface for the laying of the coil of material, and further improve the laying quality of the runway, stadium and fitness trail.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] See also Figures 1 to 5 , the utility model provides a technical solution:

[0030] A paving device for a plastic track, stadium or fitness trail of an EVA prefabricated coil comprises a base frame 1, two support plates 2 are arranged on the top of the base frames 1, placement grooves 3 are opened on the top of the support plates 2, and rolls 4 for storing coils are arranged inside the placement grooves 3, compaction rollers 5 are arranged at one end of the base frames 1, coil heating mechanisms 6 are arranged at one end of the base frames 1, and ground cleaning mechanisms 7 are arranged on one side of the coil heating mechanisms 6;

[0031] The multiple coil heating mechanisms 6 include a base plate 61, a mounting plate 62, a gas tank 63, a connecting pipe 64, a transverse pipe 65, a flame head 66 and an ignition device 67. The multiple base plates 61 are mounted on one end of the base frame 1, the multiple mounting plates 62 are welded to the top of the base plate 61, the multiple gas tanks 63 are arranged on the top of the base plate 61, the multiple connecting pipes 64 are arranged on the top of the gas tanks 63, the multiple transverse pipes 65 are mounted on the side walls of the mounting plate 62 and are connected and cooperated with the connecting pipes 64, the multiple flame heads 66 are arranged on the side walls of the transverse pipe 65, and the multiple ignition devices 67 are arranged in the middle of the transverse pipe 65.

[0032] Specifically, Figure 5 As shown, two mounting blocks 8 are provided at one end of the multiple base frames 1 away from the compaction roller 5, four T-shaped rods 9 are provided in the middle of the multiple mounting blocks 8, the bottoms of the four or more T-shaped rods 9 are fixedly connected with mounting seats 10, the bottoms of the multiple mounting seats 10 are provided with universal wheels 11, and buffer springs 12 are sleeved on the side walls of the multiple T-shaped rods 9, and the multiple buffer springs 12 are located between the mounting blocks 8 and the mounting seats 10.

[0033] Specifically, Figure 2 As shown, two groups of symmetrically arranged vertical plates 13 are arranged on the side walls of the plurality of base frames 1 , and guide rollers 14 are arranged at both ends of the plurality of vertical plates 13 .

[0034] Specifically, Figure 2 As shown, two supporting wheels 15 are symmetrically arranged on the side walls of the plurality of supporting plates 2 , and the plurality of supporting wheels 15 are used to reduce the friction between the reel 4 and the supporting plate 2 .

[0035] Specifically, Figure 2 As shown, two limit blocks 16 are bolted to the side walls of the plurality of support plates 2 , and the plurality of limit blocks 16 are movably connected to the reel 4 .

[0036] Specifically, Figure 3 As shown, a shielding top 17 is bolted to the top of the plurality of mounting plates 62 .

[0037] The EVA prefabricated coil is stored in the roll 4 on the top of the support plate 2. The device pulls the coil out of the roll 4 and lays it on the ground by moving the base frame 1. When the coil needs to be heated, the coil heating mechanism 6 starts to work, and the gas in the gas tank 63 enters the cross pipe 65 through the connecting pipe 64 and is ignited by the ignition device 67. Multiple flame heads 66 spray flames to heat the coil to ensure the adhesion between the coil and the ground. The mounting block 8, T-bar 9, mounting seat 10 and universal wheel 11 arranged at one end of the base frame 1 away from the compaction roller 5 allow the device to be easily moved to the specified position. The buffer spring 12 can alleviate the impact during the movement to ensure the installation The device is installed and operates stably. The guide roller 14 on the vertical plate 13 is used to guide the moving direction of the coil to ensure the straightness of the coil laying. The support wheel 15 on the side wall of the support plate 2 can reduce the friction between the roll 4 and the support plate 2, making it easier to pull out the coil. The movable connection between the limit block 16 and the roll 4 limits the moving range of the roll 4 on the support plate 2 to ensure the stable pulling out of the coil. The shielding top 17 on the top of the mounting plate 62 can protect the heating mechanism to prevent dust and debris from entering, while ensuring the safety of the operator. In this way, the coil can be heated before laying, thereby improving the bonding effect between the coil and the ground and ensuring the flatness and durability of the runway, stadium and fitness trail.

[0038] Specifically, Figure 4 As shown, the multiple ground cleaning mechanisms 7 include a movable rod 71, a limit head 72, a cleaning plate 73, a brush strip 74, a support spring 75 and a dust removal assembly 76. Two or more of the movable rods 71 ​​are movably arranged in the middle of the mounting plate 62. The multiple limit heads 72 are fixedly connected to the top of the movable rod 71. The multiple cleaning plates 73 are fixedly connected to the bottom of the two movable rods 71. The multiple brush strips 74 are bolted to the bottom of the cleaning plate 73. The multiple support springs 75 are sleeved on the side wall of the movable rod 71 and are located between the cleaning plate 73 and the bottom plate 61. The multiple dust removal assemblies 76 are arranged on one side of the bottom plate 61.

[0039] Specifically, Figure 5 As shown, the multiple dust removal components 76 include a vacuum cleaner 761, a vacuum tube 762 and a vacuum head 763. The multiple vacuum cleaners 761 are bolted to the top of the base plate 61, the multiple vacuum tubes 762 are arranged at the bottom of the base plate 61, and the multiple vacuum heads 763 are arranged at the bottom of the vacuum tube 762.

[0040] Before the coiled material is laid, the ground cleaning mechanism 7 starts to work. By operating the movable rod 71, the cleaning plate 73 descends, and the brush strip 74 contacts the ground to clean the ground. At the same time, the support spring 75 plays a buffering role to ensure that there is appropriate pressure between the cleaning plate 73 and the ground, thereby improving the cleaning effect. The dust and debris generated by cleaning are collected by the dust removal component 76. After the vacuum cleaner 761 is started, the dust is sucked into the vacuum cleaner 761 through the dust suction pipe 762 and the dust suction head 763. The ground cleaning mechanism 7 can effectively remove dust, debris, etc. on the ground, provide a clean base surface for the laying of the coiled material, and further improve the laying quality of the runway, stadium and fitness trail.

[0041] By adopting the above technical solution, the problem that the existing coil material laying device is unable to heat the adhesive surface of the coil material before laying to improve the flatness and adhesion of the coil material is solved. Since the coil material is in a bent state for a long time, it is difficult for the existing laying device to lay the coil material in a flat state when laying the coil material. At the same time, the coil material cannot be heated, and the adhesion of the coil material itself cannot be fully exerted.

[0042] Working principle: When the present application is in use, first, before the roll material is laid, the ground cleaning mechanism 7 starts to work, by operating the movable rod 71, the cleaning plate 73 descends, the brush strip 74 contacts the ground, and the ground is cleaned. At the same time, the support spring 75 plays a buffering role to ensure that there is appropriate pressure between the cleaning plate 73 and the ground, thereby improving the cleaning effect. The dust and debris generated by cleaning are collected by the dust removal component 76. After the vacuum cleaner 761 is started, the dust is sucked into the vacuum cleaner 761 through the dust suction pipe 762 and the dust suction head 763. The EVA prefabricated roll material is stored in the roll 4 on the top of the support plate 2. The device pulls the roll material out of the roll 4 and lays it by moving the base frame 1. On the ground, the guide roller 14 is used to guide the moving direction of the coil to ensure the straightness of the coil laying. When the coil needs to be heated to better adhere to the ground, the coil heating mechanism 6 starts to work, and the gas in the gas tank 63 enters the cross pipe 65 through the connecting pipe 64, and the gas in the cross pipe 65 is ignited by the ignition device 67. Multiple flame heads 66 spray flames to heat the coil. After the EVA coil is preheated by burning, its surface temperature will increase, which can enhance the adhesion of the EVA prefabricated coil and prevent the EVA prefabricated coil from deformation or wrinkling. During the movement of the device, the coil is initially compacted by the compaction roller 5 to ensure close contact with the ground.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
