Description

Technical Field

[0001] This utility model relates to the field of asphalt paving, specifically a heated vibratory push plate that facilitates asphalt paving. Background Technology

[0002] Asphalt is a dark brown complex mixture composed of hydrocarbons of different molecular weights and their non-metallic derivatives. It is a high-viscosity organic liquid, in a liquid state, with a black surface, and is soluble in carbon disulfide. Asphalt pavement has advantages such as smooth surface, no joints, comfortable driving, low vibration, low noise, wear resistance, no dust and easy cleaning, short construction period, simple maintenance, recyclability, and suitability for phased construction. Therefore, asphalt is often used in municipal road construction. In the process of forming asphalt pavement, asphalt needs to be laid first and then rolled into shape. During paving, a pusher plate is used to flatten the asphalt.

[0003] Existing heated asphalt pavers are equipped with control boxes to control electric heaters and other electrical equipment. These control boxes typically have wiring holes to allow cables to pass through and connect to the heaters and other electrical equipment. However, these holes are usually quite large, leaving gaps between the cable and the hole. This reduces the control box's airtightness. Furthermore, the dust present at the asphalt paving site allows external dust to easily enter the control box through these gaps, affecting the stability and lifespan of electronic components. Utility Model Content

[0004] Based on this, the purpose of this utility model is to provide a heated vibratory push plate that facilitates asphalt paving, so as to solve the technical problem that external dust can easily enter the control box through the gap between the cable and the wire hole.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a heated vibratory push plate for easy asphalt paving, comprising a push plate, an electric heater installed on the top of the push plate, a fixing frame fixed on the top of the electric heater, and a control box installed on the top of the fixing frame. The outer surface and one side of the control box are provided with wire holes, and the inner wall of the wire holes is provided with mounting grooves. A sealing airbag ring is fitted inside the mounting groove, and an inflation check valve and an exhaust valve are respectively connected to the side of the sealing airbag ring facing away from the control box. A vibratory motor is installed at the middle position of the top of the electric heater.

[0006] By adopting the above technical solution, the electric heater can heat the asphalt, making it easier for the pusher plate to flatten the asphalt.

[0007] Furthermore, the top of the control box is fitted with a top cover by multiple fastening bolts, and a sealing strip is installed at the bottom of the top cover.

[0008] By adopting the above technical solution, the top cover can be installed on the control box to cover the top of the control box.

[0009] Furthermore, the sealing strip is made of hydrogenated nitrile rubber material, and the outer wall of the sealing strip is fitted to the inner wall of the control box.

[0010] By adopting the above technical solution, the sealing strip can improve the sealing between the top cover and the control box, preventing dust from entering the control box through the gap between the top cover and the control box.

[0011] Furthermore, a hinge seat is installed inside the lower part of the fixing frame, and a push rod is rotatably connected to the hinge seat via a pin. A battery is installed inside the push rod, and a power cord extending to the outside of the push rod is connected to the battery.

[0012] By adopting the above technical solution, it is convenient for workers to push the push plate with a push rod, and the movement of the push plate can flatten the asphalt.

[0013] Furthermore, the outer wall of the push rod is fitted with an elastic sleeve, and the elastic sleeve is made of silicone rubber.

[0014] By adopting the above technical solution, the elastic sleeve can increase the friction when holding the push rod, prevent the hand from slipping, and make it easier for the staff to hold the push rod. At the same time, its elastic properties can buffer the impact force and vibration transmission generated by the push rod during operation or vibration, reduce the vibration felt by the hand or operating parts, and improve the comfort of operation.

[0015] Furthermore, the control box is electrically connected to the battery via cables, and the control box is electrically connected to the vibration motor and the electric heater via cables respectively.

[0016] By adopting the above technical solution, the battery can power the control box.

[0017] Furthermore, the inner wall of the sealing airbag ring is fitted to the outer wall of the cable, and the sealing airbag ring is made of hydrogenated nitrile rubber material.

[0018] By adopting the above technical solution, the sealing airbag ring can be expanded and tightly fitted to the outer wall of the cable, which can improve the sealing performance between the cable and the threading hole.

[0019] Furthermore, a counterweight is mounted on the top of the top cover by a plurality of fastening bolts.

[0020] By adopting the above technical solution, the counterweight can increase the overall weight.

[0021] Furthermore, heat dissipation holes are provided on both sides of the control box, and dustproof nets are installed at the openings of the heat dissipation holes by fastening bolts.

[0022] By adopting the above technical solution, the heat dissipation holes facilitate heat dissipation from the control box, preventing a large amount of heat from accumulating inside the control box.

[0023] Furthermore, the push plate is made of wear-resistant steel (such as NM360 or NM400).

[0024] By adopting the above technical solutions, the strength and wear resistance of the push plate are improved, thereby extending the service life of the push plate.

[0025] In summary, the present invention has the following main advantages:

[0026] 1. This utility model is equipped with an installation groove, a sealing airbag ring, an inflation check valve, and an exhaust valve. After the cable passes through the cable hole, the operator can inflate the sealing airbag ring through the inflation check valve. At this time, the sealing airbag ring expands inward to fit tightly against the outer wall of the cable, thereby eliminating the gap between the cable and the cable hole and improving the sealing performance of the control box. This prevents external dust from entering the control box through the gap between the cable and the cable hole, thus improving the dustproof effect of the control box. The inflation check valve prevents the air inside the sealing airbag ring from being discharged through the inflation check valve. When it is necessary to retract the sealing airbag ring, simply open the exhaust valve, and the gas inside the sealing airbag ring will be discharged through the exhaust valve.

[0027] 2. This utility model is equipped with a vibrating motor. The vibration generated by the vibrating motor is transmitted to the push plate, causing the push plate to vibrate at a high frequency when it comes into contact with asphalt. This vibration can fill the gaps between material particles, reduce air bubbles and loose areas, thereby improving the density and flatness of the material after paving. The counterweight can be added to increase the overall weight. Attached Figure Description

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0037] The embodiments of this utility model will be described below based on its overall structure.

[0038] Example 1:

[0039] A heated vibratory slab for easy asphalt paving, such as Figures 1-7 As shown, the device includes a push plate 1, an electric heater 2 mounted on the top of the push plate 1, a fixing frame 3 fixed on the top of the electric heater 2, and a control box 7 mounted on the top of the fixing frame 3. A top cover 8 is mounted on the top of the control box 7 by multiple fastening bolts. The top cover 8 can be installed on the control box 7 to cover the top of the control box 7. A hinge seat 4 is installed inside the lower part of the fixing frame 3, and a push rod 5 is rotatably connected to the hinge seat 4 by a pin. A battery 17 is installed inside the push rod 5, and a power cord 18 extending to the outside of the push rod 5 is connected to the battery 17, which allows the operator to push the push plate 1 to move by pushing the push plate 1. The movement of the push plate 1 can flatten the asphalt. A top plate 21 is mounted on the end of the push rod 5 by fastening bolts.

[0040] See Figures 1-5The control box 7 has wire holes 12 on its outer surface and one side, and the inner wall of the wire hole 12 has a mounting groove 13. The mounting groove 13 is fitted with a sealing airbag ring 14. The side of the sealing airbag ring 14 facing away from the control box 7 is connected to an inflation check valve 15 and an exhaust valve 16. A vibration motor 11 is installed at the top center of the electric heater 2. The electric heater 2 can heat the asphalt, which makes it easier for the push plate 1 to push the asphalt flat. The inner wall of the sealing airbag ring 14 fits against the outer wall of the cable. The sealing airbag ring 14 is made of hydrogenated nitrile rubber. After the sealing airbag ring 14 expands and fits tightly against the outer wall of the cable, it can improve the sealing between the cable and the wire hole 12.

[0041] Specifically, the control box 7 is electrically connected to the battery 17 via cables. The control box 7 is also electrically connected to the vibration motor 11 and the electric heater 2 via cables. The battery 17 can supply power to the control box 7. The top of the top cover 8 is fitted with a counterweight 10 via multiple fastening bolts. The counterweight 10 can increase the overall weight. The push plate 1 is made of wear-resistant steel (such as NM360 or NM400) to improve the strength and wear resistance of the push plate 1, thereby extending the service life of the push plate 1.

[0042] Example 2:

[0043] Based on the above embodiment 1, in order to improve the sealing between the top cover 8 and the control box 7, the following structure will be set.

[0044] See Figures 1-4 A sealing strip 9 is installed at the bottom of the top cover 8. The sealing strip 9 is made of hydrogenated nitrile rubber. The outer wall of the sealing strip 9 fits against the inner wall of the control box 7. The sealing strip 9 can improve the sealing between the top cover 8 and the control box 7 and prevent dust from entering the inside of the control box 7 through the gap between the top cover 8 and the control box 7.

[0045] Example 3:

[0046] Based on the above embodiment 1, the following structure will be set to make it easier for staff to hold the push rod 5.

[0047] Specifically, the outer wall of the push rod 5 is fitted with an elastic sleeve 6, which is made of silicone rubber. The elastic sleeve 6 increases the friction when the push rod 5 is held, preventing the hand from slipping, thus making it easier for the operator to hold the push rod 5. At the same time, its elastic properties buffer the impact force and vibration transmission generated by the push rod 5 during operation or vibration, reducing the vibration felt by the hand or operating parts and improving the comfort of operation.

[0048] Example 4:

[0049] Based on the above embodiment 1, the following structure will be set up in order to dissipate heat from the control box 7.

[0050] See Figures 1-5 The control box 7 has heat dissipation holes 19 on both sides. Dustproof nets 20 are installed at the opening of the heat dissipation holes 19 by fastening bolts. The heat dissipation holes 19 facilitate heat dissipation of the control box 7 and prevent a large amount of heat from accumulating inside the control box 7. The dustproof nets 20 can improve the dustproof effect and prevent external dust from entering the control box 7 through the heat dissipation holes 19.

[0051] The working principle of this utility model is as follows: First, before use, after the cable passes through the threading hole 12, the operator can inflate the sealing airbag ring 14 through the inflation one-way valve 15. At this time, the sealing airbag ring 14 expands inward to fit tightly against the outer wall of the cable, thereby eliminating the gap between the cable and the threading hole 12 and preventing external dust from entering the control box 7 through the gap between the cable and the threading hole 12. The battery 17 inside the push rod 5 supplies power to the control box 7. The control box 7 is connected to the vibration motor 11 and the electric heater 2 through cables to realize the start and stop of both and parameter control. When in use, the electric heater 2 is started. The vibrating motor 11 and the push rod 5 are used by the worker. The elastic sleeve 6 can improve the worker's grip comfort. The push rod 5 pushes the push plate 1 to move. When the electric heater 2 is working, it generates heat and transfers it to the push plate 1 to heat the asphalt in contact, reduce the viscosity of the asphalt and make it easier to push flat. At the same time, the vibrating motor 11 is installed at the top center of the electric heater 2. When working, it generates high-frequency vibration. The vibration is transmitted to the push plate 1 through the electric heater 2. The push plate 1 contacts the asphalt in the vibrating state, which can fill the gaps between asphalt particles, reduce air bubbles and loose areas, and improve the density and smoothness after paving.
