Description

Technical Field

[0001] This invention relates to the field of construction technology for plastic sports fields, and specifically to a sled-type plastic fluid leveling device. Background Technology

[0002] Synthetic running tracks, also known as all-weather running tracks, are composed of polyurethane prepolymer, mixed polyesters, waste tire rubber, EPDM rubber granules or PU granules, pigments, additives, and fillers. Synthetic running tracks are characterized by good flatness, high compressive strength, appropriate hardness and elasticity, and stable physical properties, which are conducive to athletes' speed and technique, effectively improving athletic performance and reducing the rate of falls and injuries. Synthetic running tracks also possess a certain degree of UV resistance and aging resistance, making them internationally recognized as the best all-weather outdoor sports venues. Currently, the vast majority of sports venues use synthetic running tracks.

[0003] The flatness requirements for synthetic running tracks are high, and the thickness of the synthetic material during construction needs to be controlled. The construction of a synthetic running track involves evenly spreading and leveling the liquid synthetic material poured onto the site. However, due to the large area of ​​the construction site, evenly spreading and leveling the material is difficult, time-consuming, labor-intensive, and it is not easy to guarantee the desired flatness. Summary of the Invention

[0004] To address the aforementioned problems, this invention proposes a sled-type plastic fluid leveling device, designed to facilitate rapid leveling of liquid plastic materials on a construction site and improve the quality of plastic field construction. The specific technical solution is as follows:

[0005] A sled-type plastic fluid leveling device includes a pair of sled-type supports for sliding on the ground on both sides of the plastic field to be constructed, a rectangular cross-section straight ruler supported on the pair of sled-type supports, and a pair of traction ropes correspondingly connected to the pair of sled-type supports. Each sled-type support includes a pair of horizontal sliding rods in contact with the ground, a pair of transverse connecting ribs connected between the pair of horizontal sliding rods, and a pair of parallel diagonal rods correspondingly and vertically arranged on the pair of transverse connecting ribs. The rectangular cross-section straight ruler is installed and positioned between the pair of parallel diagonal rods so that the lower plane of the rectangular cross-section straight ruler is inclined relative to the ground. One end of each pair of horizontal sliding rods is provided with an arc-shaped rod that curves upward.

[0006] Preferably, the lowest edge of the rectangular cross-section straight ruler is supported on the horizontal sliding rod.

[0007] Preferably, the horizontal slide bar is made of round steel, and the diameter of the horizontal slide bar is equal to the thickness of the plastic fluid when it is stretched flat.

[0008] As a further improvement of the present invention, an inclined bridge plate perpendicular to the parallel inclined bars is provided between the upper ends of the pair of parallel inclined bars, and a tightening screw for fixing the rectangular cross-section straight ruler is provided on the inclined bridge plate.

[0009] Preferably, the rectangular cross-section straight ruler is a hollow rectangular cross-section straight ruler.

[0010] Preferably, one end of the traction rope is connected to the parallel diagonal bar.

[0011] Preferably, the parallel diagonal bar has an inclination angle of 45° relative to the ground.

[0012] As a further improvement of the present invention, a sled anti-jump device is also provided on the sled-type support to prevent the sled-type support from jumping in the vertical direction when it slides on the ground. The sled anti-jump device includes four uprights erected on the pair of horizontal sliding rods, a horizontal bridge plate connected to the upper part of the four uprights and located above the pair of parallel diagonal rods, a guide hole opened on the horizontal bridge plate, a gravity hanger rod that moves through the guide hole in the vertical direction, a support flange set on the upper end of the gravity hanger rod, and a gravity block set on the lower end of the gravity hanger rod. A compression spring is provided on the outer circle of the gravity hanger rod and located between the support flange and the horizontal bridge plate.

[0013] Preferably, the number of gravity lifting rods is one pair.

[0014] Preferably, the center of the gravity block is provided with a barbell mounting hole perpendicular to the horizontal slide bar, a barbell shaft is installed through the barbell mounting hole, and disc dumbbells for increasing gravity are provided at both ends of the barbell shaft.

[0015] Preferably, the connection between the disc dumbbell and the barbell shaft is a detachable connection.

[0016] In this invention, a rope loop is provided on the parallel inclined bar, and one end of the traction rope is connected to the rope loop.

[0017] Preferably, the two ends of the barbell shaft are fixed with pressure rings and clamping screws, respectively.

[0018] The working principle of the aforementioned sled anti-jump device is as follows: The weight block with disc-shaped dumbbells generates a large gravity, which is elastically suspended through compression springs and gravity rods, thus forming a downward elastic clamping force on the sled-type support. When the sled-type support is pulled by the traction rope at a relatively fast speed, if it encounters uneven ground, without the sled anti-jump device, the sled-type support may experience momentary detachment from the ground (including complete detachment and partial detachment), resulting in jumping or vibration, which would seriously affect the accuracy of plastic fluid leveling. However, when the sled anti-jump device is installed, because there is always an elastic buffer force pressing down on the sled-type support during the movement, when encountering uneven ground, the vibration and impact energy received by the sled-type support can be absorbed and converted by the compression spring, thus allowing the sled-type support to always stay on the ground and move smoothly, thereby ensuring the accuracy of plastic fluid leveling.

[0019] The method of using the sled-type plastic fluid leveling device is as follows: Place a pair of sled-type supports on both sides of the work area. Insert a rectangular cross-section straight ruler between the parallel diagonal bars of the pair of sled-type supports. After adjusting the distance between the pair of sled-type supports, tighten the rectangular cross-section straight ruler with the tightening screws. Then, two operators simultaneously pull the pair of sled-type supports to move in the same direction along the work area. During the movement, the bottom edge of the rectangular cross-section straight ruler enters the plastic fluid and smooths the fluid. During the movement of the pair of sled-type supports, the sled anti-jump device can always elastically press down on the sled-type supports and use the expansion and contraction of the compression spring to absorb and convert the energy of vibration and impact on the sled-type supports, thereby preventing the sled-type supports from vibrating or jumping due to uneven ground and ensuring the accuracy of plastic fluid leveling.

[0020] The beneficial effects of this invention are:

[0021] First, the present invention provides a sled-type plastic fluid leveling device, in which a straight ruler for leveling the plastic fluid is set on a pair of sled-type supports. By having two operators pull the pair of sled-type supports simultaneously, the straight ruler can be used to level the plastic fluid. The device is easy to operate and produces good flatness, thereby improving the quality and efficiency of plastic field construction.

[0022] Secondly, in the sled-type plastic fluid leveling device of the present invention, a pair of parallel diagonal bars on the sled-type support are inclined so that the bottom edge of the rectangular cross-section straight ruler forms the blade of the scraper, and the plane adjacent to the bottom edge forms the angle of the scraper, which has a good leveling effect.

[0023] Third, the sled-type plastic fluid leveling device of the present invention is equipped with a sled anti-jump device, which can use the gravity of the sled anti-jump device to always elastically press the sled-type support, and absorb and convert the energy of vibration and impact on the sled-type support through the extension and contraction of the compression spring, thereby preventing the sled-type support from vibrating or jumping due to uneven ground, ensuring the accuracy of plastic fluid leveling, and thus further improving the quality of plastic field construction.

[0024] Fourth, the sled-type plastic fluid leveling device of the present invention can hang disc dumbbells of different weights on the barbell shaft as needed, thereby improving the adaptability and stability of the sled-type support to prevent jumping or vibration. Attached Figure Description

Each sled-type support 1 includes a pair of horizontal sliding rods 4 in contact with the ground, a pair of transverse connecting ribs 5 connected between the pair of horizontal sliding rods 4, and a pair of parallel diagonal rods 6 correspondingly erected obliquely on the pair of transverse connecting ribs 5. The rectangular cross-section straight ruler 2 is installed and positioned between the pair of parallel diagonal rods 6 so that the lower plane of the rectangular cross-section straight ruler 2 is inclined relative to the ground. One end of the pair of horizontal sliding rods 4 is provided with an arc-shaped rod 7 that curves upward.

[0031] Preferably, the bottom edge of the rectangular cross-section straight ruler 2 is supported on the horizontal slide bar 4.

[0032] Preferably, the horizontal slide bar 4 is made of round steel, and the diameter of the horizontal slide bar 4 is equal to the thickness of the plastic fluid when it is flattened.

[0033] As a further improvement to this embodiment, an inclined bridge plate 8 perpendicular to the parallel inclined bars 6 is provided between the upper ends of the pair of parallel inclined bars 6, and a tightening screw 9 for fixing the rectangular cross-section straight ruler 2 is provided on the inclined bridge plate 8.

[0034] Preferably, the rectangular cross-section straight ruler 2 is a hollow rectangular cross-section straight ruler.

[0035] Preferably, one end of the traction rope 3 is connected to the parallel diagonal bar 6.

[0036] Preferably, the parallel diagonal bar 6 has an inclination angle of 45° relative to the ground.

[0037] As a further improvement of this embodiment, a sled anti-jump device 10 is also provided on the sled-type support 1 to prevent the sled-type support 1 from jumping in the vertical direction when it slides on the ground. The sled anti-jump device 10 includes four uprights 11 erected on the pair of horizontal sliding bars 4, a horizontal bridge plate 12 connected to the upper part of the four uprights 11 and located above the pair of parallel diagonal bars 6, a guide hole opened on the horizontal bridge plate 12, a gravity hanger 13 that moves through the guide hole in the vertical direction, a support flange 14 provided on the upper end of the gravity hanger 13, a gravity block 15 provided on the lower end of the gravity hanger 13, and a compression spring 16 provided on the outer circle of the gravity hanger 13 and located between the support flange 14 and the horizontal bridge plate 12.

[0038] Preferably, the number of gravity lifting rods 13 is one pair.

[0039] Preferably, the center of the gravity block 15 is provided with a barbell mounting hole 17 perpendicular to the horizontal slide bar 4, a barbell shaft 18 is installed through the barbell mounting hole 17, and disc dumbbells 19 for increasing gravity are provided at both ends of the barbell shaft 18.

[0042] Preferably, the two ends of the barbell shaft 18 are fixed to the disc dumbbell 19 by pressure rings 21 and clamping screws 22, respectively.

[0043] The working principle of the above-mentioned sled anti-jump device 10 is as follows: The gravity block 15 with disc dumbbell 19 generates a large gravity, which is elastically suspended through the compression spring 16 and gravity rod 13, thereby forming a downward elastic clamping force on the sled support 1; when the sled support 1 is pulled by the traction rope 3 to move at a relatively fast speed, if the ground is uneven, without the sled anti-jump device 10, the sled support 1 may experience a momentary detachment from the ground (including overall detachment and partial detachment), which will seriously affect the accuracy of plastic fluid leveling; however, when the sled anti-jump device 10 is set, since the sled support 1 always has an elastic buffer force pressing down on the sled support 1 during the movement, when encountering uneven ground, the energy of the impact on the sled support 1 can be absorbed and converted by the compression spring 16, so that the sled support 1 can always stick to the ground and move smoothly, thereby ensuring the accuracy of plastic fluid leveling.

[0044] The method of using the sled-type plastic fluid leveling device is as follows: Place a pair of sled-type supports 1 on both sides of the construction site. Insert a rectangular cross-section straight ruler 2 between the parallel diagonal bars 6 of the pair of sled-type supports 1. After adjusting the distance between the pair of sled-type supports 1, tighten and fix the rectangular cross-section straight ruler 2 with the tightening screws 9. Then, two operators simultaneously pull the pair of sled-type supports 1 to move in the same direction along the site. During the movement, the bottom edge of the rectangular cross-section straight ruler 2 enters the plastic fluid and smooths the plastic fluid. During the movement of the pair of sled-type supports 1, the sled anti-jump device 10 can always elastically press the sled-type supports 1, and use the extension and contraction of the compression spring 16 to absorb and convert the energy of vibration and impact on the sled-type supports, thereby preventing the sled-type supports 1 from vibrating or jumping due to uneven ground, and ensuring the accuracy of plastic fluid leveling.

[0045] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
