Description

Technical Field

[0001] This invention relates to the field of asphalt paving technology, and in particular to a method of using an asphalt paving spraying device. Background Technology

[0002] Asphalt pavement refers to various types of road surfaces constructed by incorporating road asphalt materials into mineral materials. Asphalt binders enhance the ability of paving aggregates to resist damage from traffic and natural factors, resulting in a smooth, dust-free, impermeable, and durable surface. Therefore, asphalt pavement is one of the most widely used high-grade road surfaces in road construction. Asphalt pavers are widely used in the construction and maintenance of asphalt pavements for highways, airports, ports, parking lots, and urban roads. However, existing asphalt paving equipment has a fixed structure, limiting its application to specific road sections. This increases the difficulty and reduces efficiency under varying road conditions, leading to longer construction times and making it difficult to guarantee the quality of the paved surface. Summary of the Invention

[0003] In view of the above, the present invention provides an asphalt paving spraying device, which solves the technical problems of limited application range and high construction difficulty of asphalt paving tools in traditional construction. By setting up an installation frame, the asphalt paving spraying device can be connected to different construction machinery according to different construction conditions, thereby improving the applicability of the device. By adjusting the height and horizontal position of the storage box, the asphalt can be accurately sprayed onto the spraying location.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0005] An asphalt paving spraying device includes:

[0006] Mounting brackets for installation on vehicles;

[0007] A height-adjustable sliding plate mounted on the mounting bracket;

[0008] Several sliders are slidably mounted on the sliding plate;

[0009] A storage box detachably connected to the slider, the storage box having a hollow interior forming an accommodating space, and an inlet and an outlet communicating with the accommodating space, respectively, are provided at the top and bottom of the storage box; and

[0010] A limiting member is installed on the slider and can be adjusted to move closer to or away from the sliding plate. By sliding the slider along the sliding plate, the horizontal position of the storage box is changed, and the limiting member is moved closer to the sliding plate so that the limiting member is locked onto the sliding plate, thereby fixing the slider and the sliding plate.

[0011] A further improvement of the asphalt paving and spraying device of the present invention is that it further includes fixing blocks fixed to both ends of the sliding plate, two connecting boxes fixed to the mounting frame corresponding to the fixing blocks, a slide rail opened vertically on the side of the connecting box for sliding the fixing blocks, a drive rod horizontally passing through the two connecting boxes, a gear fixed to the drive rod and located in the connecting box, and teeth formed in the fixing block and meshing with the gear.

[0012] The drive rod rotates, which in turn drives the gear to rotate, thereby causing the fixed block to move up or down along the slide rail, thus changing the height of the sliding plate.

[0013] A further improvement of the asphalt paving and spraying device of the present invention is that it further includes a locking tooth disposed on the fixed block and located on both sides of the tooth, a first support block fixed to the inner wall of the connecting box corresponding to the locking tooth, a limiting rod made of magnetic material that is horizontally inserted through the first support block, an electromagnetic block disposed on the side of the limiting rod away from the locking tooth and fixed to the inner wall of the connecting box, and a spring fixed between the limiting rod and the electromagnetic block.

[0014] By energizing the electromagnetic block, the electromagnetic block attracts the limiting rod to move away from the locking tooth, thereby compressing the spring and disengaging from the locking tooth, so that the gear can drive the fixed block to move.

[0015] A further improvement of the asphalt paving and spraying device of the present invention is that it further includes a plurality of second support blocks fixed to the side of the slider away from the sliding plate, a first enclosure plate fixed to the plurality of second support blocks, and a second enclosure plate arranged opposite to the first enclosure plate.

[0016] The first and second enclosures are respectively attached to both sides of the storage box, and then fixedly connected to the first and second enclosures with threaded rods, so that the first and second enclosures clamp the storage box.

[0017] A further improvement of the asphalt paving and spraying device of the present invention is that it further includes a groove formed in the sliding plate and a toothed groove provided in the groove and corresponding to the limiting member, wherein the limiting member is inserted into the toothed groove to fix the sliding plate and the slider.

[0018] A further improvement of the asphalt paving and spraying device of the present invention is that the limiting member includes a guide rail disposed on the slider and extending along the width direction of the slider, a limiting plate slidably disposed on the guide rail, and a limiting section formed on the top of the limiting plate and for insertion into the tooth groove.

[0019] By adjusting the limiting plate along the guide rail, the limiting segment is inserted into the toothed groove to fix the position of the slider.

[0020] A further improvement of the asphalt paving and spraying device of the present invention is that two guide rails are provided at intervals along the height direction of the slider.

[0021] The limiting component also includes a threaded rod vertically screwed into the two guide rails and a cam sleeved on the threaded rod and located between the two guide rails. The cam is elliptical and its side is attached to the limiting plate.

[0022] By screwing the threaded rod, the cam is rotated, thereby pushing the limiting plate towards the sliding plate, so that the limiting segment is inserted into the tooth groove.

[0023] A further improvement of the asphalt paving and spraying device of the present invention is that the tooth groove includes a plurality of outwardly protruding protrusions spaced apart, the top of the protrusions is formed with an arc, the end of the limiting section near the tooth groove is arc-shaped and is locked between two adjacent protrusions, and the end of the limiting section is in contact with the arc surface.

[0024] A further improvement of the asphalt paving and spraying device of the present invention is that the top of the slider is provided with two rollers, the limiting section is disposed between the two rollers, and the limiting member has an arc-shaped groove that matches the roller on the side of the roller.

[0025] A method for using an asphalt paving spraying device includes the following steps:

[0026] Adjust the height of the sliding plate to change the height of the storage box;

[0027] Slide several sliders along the sliding plate to change the horizontal position of the storage box, and then move and adjust the limiting member so that the limiting member is locked on the sliding plate, thereby fixing the slider and the limiting plate, so that several storage boxes correspond to the position to be constructed.

[0028] Open the outlet of the storage box and drive the vehicle along the construction site so that the asphalt flows out of the outlet of the containment space and is spread on the construction site.

[0029] This invention relates to an asphalt paving and spraying device. By setting up an installation frame, the device can be connected to different vehicles according to different construction conditions, improving its applicability. A connecting box is installed on the installation frame, and a drive rod passes through the connecting box. The teeth of the fixing block mesh with a gear, and by rotating the drive rod, the fixing block moves upward, thereby changing the height of the sliding plate and thus the height of the storage box. A sliding groove is provided on the sliding plate, and a slider is installed in the groove. A limiting member is installed between the storage box and the sliding plate. When the slider moves the storage box to a designated position, the limiting member controls the storage box to fix it, preventing displacement during spraying and improving the uniformity of asphalt spraying.

Detailed Implementation

[0039] To facilitate understanding of the present invention, the following description is provided in conjunction with the accompanying drawings and embodiments.

[0040] Please see Figures 1 to 3 The present invention provides an asphalt paving spraying device, comprising:

[0041] Mounting bracket 1 for installation on vehicles;

[0042] A height-adjustable sliding plate 2 is mounted on the mounting bracket 1;

[0043] Several sliders 24 are slidably disposed on the sliding plate 2;

[0044] A storage box 4 is detachably connected to the slider 24. The storage box 4 has a hollow interior forming a receiving space, and its top and bottom are respectively provided with an inlet and an outlet communicating with the receiving space. Asphalt is added to the receiving space through the inlet and flows out of the receiving space through the outlet; and

[0045] A limiting member is installed on the side of the slider near the sliding plate 2 and can be adjusted to move closer to or away from the sliding plate 2. By adjusting the height of the sliding plate 2, the height of the storage box 4 is changed. By sliding the slider 24 along the sliding plate 2, the horizontal position of the storage box 4 is changed, and the limiting member is moved closer to the sliding plate 2 so that the limiting member is locked onto the sliding plate 2, thereby fixing the slider 24 and the sliding plate 2.

[0046] A preferred embodiment of the asphalt paving and spraying device of the present invention is as follows: Figure 1 and Figure 2 As shown, it also includes fixing blocks 21 fixed to both ends of the sliding plate 2, two connecting boxes 11 fixed to the mounting bracket 1 corresponding to the fixing blocks 21, a slide rail opened vertically on the side of the connecting box 11 for sliding the fixing blocks 21, a drive rod 13 horizontally passing through the two connecting boxes 11, a gear 131 fixed to the drive rod 13 and located in the connecting box 11, and teeth 211 formed in the fixing block 21 and meshing with the gear 131;

[0047] The drive rod 13 rotates to drive the gear 131 to rotate, thereby causing the fixed block 21 to move up or down along the slide rail to change the height of the sliding plate.

[0048] Furthermore, such as Figure 2 and Figure 3 As shown, it also includes a locking tooth 212 disposed on the fixing block 21 and located on both sides of the tooth 211, a first support block fixed to the inner wall of the connecting box 11 corresponding to the locking tooth 212, a limiting rod 113 made of magnetic material that is horizontally inserted through the first support block, an electromagnetic block 111 disposed on the side of the limiting rod 113 away from the locking tooth 212 and fixed to the inner wall of the connecting box 11, and a spring 112 fixed between the limiting rod 113 and the electromagnetic block 111;

[0049] By energizing the electromagnetic block 111, the electromagnetic block 111 is filled with magnetic force and moves away from the locking tooth 212, attracting the limiting rod 113. As a result, the limiting rod 113 disengages from the locking tooth 212 and compresses the spring 112, so that the gear 121 can drive the fixed block 21 to move. When the fixed block 21 moves along the slide to a specified height, the electromagnetic block 111 is de-energized, and the spring 112 rebounds to push the limiting rod 113 into the locking tooth 212, thereby fixing the fixed block 21 and the slide.

[0050] Furthermore, such as Figure 1 and Figure 4 As shown, it also includes a threaded section fixed to the body of the drive rod 13, a drive motor 14 fixed to the mounting bracket 1, a rotating shaft provided on the drive motor 14, and a worm gear 141 fixed to the rotating shaft and meshing with the threaded section;

[0051] The drive motor 14 controls the rotation of the rotating shaft, which in turn drives the worm gear 141 to rotate, thereby driving the drive rod 13 to rotate.

[0052] Preferably, the mounting bracket 1 includes a crossbar for fixed connection to the vehicle and three side bars fixed at intervals on one side of the crossbar. Two connecting boxes 11 are fixed to the two side bars located on the outer side. A connecting block 12 is fixedly connected to the end of the middle side bar. An installation space is formed inside the connecting block 12. A drive rod 13 passes through the installation space, and a worm gear 141 is installed in the installation space.

[0053] Specifically, such as Figure 1 and Figure 5 As shown, it also includes a plurality of second support blocks 242 fixed to the side of the slider 24 away from the sliding plate 2, a first enclosure plate 31 fixed to the plurality of second support blocks, and a second enclosure plate 32 disposed opposite to the first enclosure plate 31.

[0054] The first enclosure 31 and the second enclosure 32 are respectively attached to both sides of the storage box 4, and then fixedly connected to the first enclosure 31 and the second enclosure 32 by threaded rods, so that the first enclosure 31 and the second enclosure 32 clamp the storage box 4.

[0055] Preferably, the two sides of the enclosure are bent outward to form edges, and the threaded rod passes through the opposite edges.

[0056] Furthermore, such as Figure 5 and Figure 6 As shown, it also includes a slide groove 23 formed in the slide plate 2 and a toothed groove 231 provided in the slide groove 23 and corresponding to the limiting member. The limiting member is inserted into the toothed groove 231 to fix the slide plate 2 and the slider 24.

[0057] Furthermore, such as Figure 5 and Figure 6 As shown, the limiting member includes a guide rail 26 disposed on the slider 24 and extending along the width direction of the slider, a limiting plate 25 slidably disposed on the guide rail 26, and a limiting section 251 formed on the top of the limiting plate 25 and for insertion into the tooth groove 231.

[0058] By adjusting the limiting plate along the guide rail 26, the limiting segment 251 is inserted into the toothed groove 231 to fix the position of the slider 24.

[0059] Specifically, a horizontal guide groove 22 is provided in the middle of the side of the sliding plate 2, a sliding groove 23 is provided at the top of the guide groove 22, and a groove is provided at the bottom of the guide groove 22 for the roller 241 at the bottom of the slider 24 to slide.

[0060] Specifically, there are two guide rails 26 spaced apart along the height direction of the slider 24;

[0061] The limiting component also includes a threaded rod vertically screwed into the two guide rails 26 and a cam 27 sleeved on the threaded rod and located between the two guide rails 26. The cam 27 is elliptical and its side is attached to the limiting plate.

[0062] By screwing the threaded rod, the cam 27 is rotated, thereby pushing the limiting plate 25 towards the tooth groove 231, so that the limiting segment 251 is inserted into the tooth groove 231.

[0063] Specifically, the top of the slider 24 is provided with two circular rollers 241, the limiting segment 251 is disposed between the two rollers 241, and the limiting member has an arc-shaped groove that matches the roller on the side of the roller 241.

[0064] Specifically, the tooth groove 231 includes a plurality of protrusions that are spaced apart and protrude outwards. The top of the protrusions forms an arc. The end of the limiting section near the tooth groove is arc-shaped and is locked between two adjacent protrusions. The end of the limiting section is in contact with the arc surface.

[0065] Specifically, a return spring is fixedly connected between the guide rail 26 and the limiting plate 25. The roller 241 pushes the limiting plate 25 and the return spring returns, so that the limiting segment 251 disengages from the tooth groove 231, preventing the limiting segment 251 and the tooth groove 231 from locking up, so that the roller can slide smoothly along the slide groove 23.

[0066] This invention relates to an asphalt paving and spraying device. By setting up an installation frame, the device can be connected to different vehicles according to different construction conditions, improving its applicability. A connecting box is installed on the installation frame, and a drive rod passes through the connecting box. The teeth of the fixing block mesh with a gear, and by rotating the drive rod, the fixing block moves upward, thereby changing the height of the sliding plate and thus the height of the storage box. A sliding groove is provided on the sliding plate, and a slider is installed in the groove. A limiting member is installed between the storage box and the sliding plate. When the slider moves the storage box to a designated position, the limiting member controls the storage box to fix it, preventing displacement during spraying and improving the uniformity of asphalt spraying.

Then the threaded rod of the limiting member is screwed to drive the cam 27 to rotate, thereby pushing the limiting plate 25 towards the slide groove 23, so that the limiting section 251 is inserted into the tooth groove 231, thereby fixing the storage boxes 4.

[0068] Asphalt is added into the storage space through the inlet of storage box 4. The vehicle is driven to move along the construction site, and the outlet of the storage box is opened so that the asphalt can be sprayed onto the ground to be paved.

[0070] Adjust the height of the sliding plate 2 to change the height of the storage box 4;

[0071] Slide several sliders 24 along the sliding plate 2 to change the horizontal position of the storage box 4, and then move the adjusting limit member so that the limit member is locked on the sliding plate 2, thereby fixing the slider 24 and the sliding plate 2, so that the several storage boxes correspond to the position to be constructed.

[0072] Open the outlet of the storage box 4 and drive the vehicle along the construction site so that the asphalt flows out of the outlet of the containment space and is spread on the construction site.
