Abstract
Description
Technical Field
[0001] This utility model relates to the field of asphalt pavement technology, and in particular to an asphalt pavement paving device. Background Technology
[0002] Asphalt materials have good wear resistance and durability. Laying asphalt on the road surface can improve the service life of the road surface. At the same time, asphalt pavement has good smoothness, which can improve the comfort and safety of vehicles during driving. Asphalt pavement can also prevent rainwater from penetrating into the lower layer of the road surface, reducing road damage. In the specific paving process, asphalt pavement paving equipment is used to spread the asphalt on the road surface.
[0003] Existing asphalt paving equipment is used for highway paving and narrow rural road paving. Narrow road paving requires the use of paving carts, which are manually pushed and pulled for paving. However, during the process, because the asphalt is hot and loose when it is first laid, it will slide to the sides. Therefore, it is necessary to manually correct it by picking up a rake or a wooden board. Since the road surface to be paved is relatively long, it causes workers to work for a long time, become overworked, and consumes a lot of time and energy. At the same time, it cannot be effectively adjusted according to the width of the existing narrow road paving, requiring multiple back-and-forth paving, which wastes time.
[0004] Therefore, we propose an asphalt pavement paving device to solve the above problems. Utility Model Content
[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an asphalt pavement paving device.

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0022] Reference Figure 1-4 An asphalt pavement paving device includes: a paving device 1, with a feed hopper 11 fixedly installed on the upper end of the paving device body 1 for convenient placement and storage of asphalt and effective paving; lifting devices 2 fixedly installed on both sides of the paving device 1 for effective height adjustment in different paving environments; a ball screw 22 connected inside the lifting device 2 via a fixed disc 21 for effective rotation of the ball screw 22 and to prevent jamming during rotation; and a rotating handle 24 connected to the upper end of the ball screw 22 for easy rotation. Hand 24 controls the rotation of ball screw 22, which drives the fixed block 23 to rise and fall. The fixed block 23 is connected to the middle end of ball screw 22. The surface of fixed block 23 is connected to translation device 3, which facilitates the fixed block 23 to drive translation device 3 to rise and fall. The translation device 3 is equipped with a sliding rod 32, which allows the limiting block 33 inside the translation device 3 to slide on the sliding rod 32. A movable baffle 34 is installed at the center of the sliding rod 32 through the limiting block 33, which facilitates the effective adjustment of the movable baffle 34 according to the different heights of asphalt paving.
[0023] Furthermore, refer to Figure 1 and Figure 2 It can be seen that the surface of the lifting device 2 is provided with a through groove that matches the fixed block 23, so that the fixed block 23 can slide up and down inside the through groove. One end of the ball screw 22 inside the lifting device 2 is connected to the fixed disc 21 by a bearing, so that the ball screw 22 can rotate effectively and prevent jamming during rotation. The middle end of the fixed block 23 is provided with a screw hole that matches the ball screw 22. The diameter of the fixed disc 21 is larger than the diameter of the screw hole, so that it can rotate easily through the matching screw hole during operation and prevent the device from jamming or loosening when rotating.
[0024] Furthermore, refer to Figure 1 and Figure 2 It can be seen that the upper surface of the lifting device 2 is provided with a slot that matches the rotating handle 24, so that the rotating handle 24 can be connected to the ball screw 22 for rotation and prevent jamming. A limiting rod 25 is inserted inside the rotating handle 24, and the limiting rod 25 is cylindrical. The upper surface of the lifting device 2 is provided with a concave hole that matches the limiting rod 25. The concave hole provided at the upper end of the lifting device 2 is not through and is convenient to rotate to a suitable height for limiting and fixing, so as to prevent it from falling off and affecting the paving work.
[0025] Furthermore, refer to Figure 1 and Figure 3 It can be seen that the upper end of the paving device body 1 is provided with a through groove corresponding to the feed bin 11, which facilitates effective connection and allows the asphalt to slide down for paving work. The upper end of the feed bin 11 is equipped with two sets of closed doors 13 through hinges 12 to prevent the asphalt from being exposed to the feed bin 11 for too long and the area exposed to the ground, which would cause the asphalt to lose heat and affect the subsequent paving and compaction work. The two sets of closed doors 13 are fixed with handles on the top, which makes it easy to pull the closed doors 13 to open and close.
[0026] Furthermore, refer to Figure 1 and Figure 3 It can be seen that the surface of the translation device 3 is provided with a through groove, which facilitates the effective adjustment and sliding of the limiting block 33 inside the through groove. The sliding rod 32 is fixedly connected inside the translation device 3. A buffer spring 31 is sleeved on one side of the sliding rod 32 and abuts against one side of the limiting block 33. When the movable baffle 34 abuts against the roadside, it is effectively fixed and abutted by the buffer spring 31 to prevent loosening from affecting the paving work.
[0027] Furthermore, refer to Figure 3 and Figure 4 It can be seen that the movable baffle 34 has a groove at its end that matches the limiting block 33, which facilitates effective adjustment according to the different thicknesses of the asphalt being laid, preventing the asphalt from exceeding the height of the movable baffle 34. The movable baffle 34 is long and narrow, and the front end of the movable baffle 34 is set in an inclined shape to facilitate blocking the asphalt from sliding to both sides and reducing the time for manual correction.
[0028] Working principle: In use, the operator rotates the hinge 12 and manually pulls the handle to open the closed door 13. Asphalt is then poured into the feed hopper 11 by a loader. The feed hopper 11 is connected to the paving device 1, which paves the road surface. Simultaneously, a sliding rod 32 is installed inside the translation device 3. A limit block 33 is installed at the center of the sliding rod 32, so that one end of the sliding rod 32 is fitted with a buffer spring 31 that abuts against one side of the limit block 33. Furthermore, the limit block 33 is inserted... The movable baffle 34 slides up and down inside the groove at the end of the movable baffle 34. The movable baffle 34 is pulled to abut against the roadside and fixed according to the width of the road surface to prevent asphalt from slipping. In addition, lifting devices 2 are fixedly installed and connected on the left and right sides of the paving device 1. By manually pulling out the limiting rod 25 inside the limiting hole, the manual rotating handle 24 drives the ball screw 22. The bearing inside the fixed disc 21 rotates, causing the fixed block 23 to rise and fall through the rotation of the ball screw 22. The surface of the fixed block 23 is connected to a translation device 3.
[0029] The above is the complete working principle of this utility model.
