Description

Technical Field

[0001] The invention relates to the technical field of road construction, in particular to an asphalt concrete road construction device. Background Art

[0002] During asphalt concrete road construction, the roadbed must first be leveled and compacted before the stone and asphalt mixture is laid. Paving the road surface is relatively simple, requiring a mobile device carrying a specialized asphalt paving device to move along the road surface. However, for roadside manhole covers, laying asphalt around them is more complex due to alignment issues with the road surface. This requires excavating a trench around the manhole opening to reserve space for the asphalt. The manhole cover is then removed from the manhole seat, and a concrete adjustment ring is secured to the seat. The stop ring is then inserted into a precast concrete ring using a socket-and-spigot arrangement. The trench around the stop ring is then filled with asphalt in layers and compacted. Once the asphalt is filled to the appropriate height, the stop ring is removed, and the manhole cover is reinserted into the space reserved for installation after the stop ring is removed. The concrete adjustment ring is then connected to the manhole cover and leveled with the asphalt pavement using a roller.

[0003] During the process of filling the asphalt in layers and compacting the pits around the limiting well ring, since the construction needs to be carried out around the limiting well ring, manual operation requires constant movement and adjustment of the working position, and the movement process also requires control of the asphalt filling amount and the compaction strength. Therefore, manual operation has the problems of low efficiency and difficulty in uniform filling and compaction. Currently, automated construction equipment has gradually been adopted for operation. The existing related technology integrates asphalt filling equipment and compaction equipment on a mobile bracket, and provides a rotating platform that can rotate around the wellhead on the mobile bracket. The rotating platform drives the asphalt filling equipment and compaction equipment to rotate and lay the asphalt at the same time, thereby realizing the automatic uniform asphalt laying process of the pits around the wellhead. However, this method has high requirements for the positioning of the mobile bracket. Not only does it need to ensure that the center of the rotating platform coincides with the center of the wellhead, but it also needs to take into account the problem of the reaction force generated during the vibration compaction process causing the mobile bracket to gradually deviate. Once this occurs, it will make it difficult to carry out uniform asphalt paving and compaction around the wellhead. For example, the patent with publication number CN115506212B discloses a method for laying asphalt around a manhole cover. During the laying process, the laying device is moved to the top of the manhole cover by casters. During the laying process, the center of the laying device must correspond to the center of the manhole cover. However, there is a lack of positioning reference between the laying device and the manhole cover, which makes it difficult to perform fast and accurate positioning and requires repeated adjustments. In addition, during the laying process, height-adjustable support legs are used as positioning supports to make the support legs contact the ground to ensure stability when laying asphalt. However, the support legs only contact the ground by friction and do not form a vertical limit. During the vibration compaction process, the vibration reaction force will cause the support legs to shake slightly and cause displacement, deviating from the rotation positioning center.

They do not indicate or imply that the devices or components referred to must have a specific direction, be constructed, or operate in a specific direction. Therefore, they should not be construed as limiting the present invention.

[0027] The terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the quantity of the technical features indicated. Therefore, features specified as "first" or "second" may explicitly or implicitly include one or more of such features; and in the description of the invention, unless otherwise specified, "plurality" means two or more.

[0028] Example 1 like Figures 1 to 8As shown, an embodiment of the present invention provides an asphalt concrete road construction device, including a concrete adjustment ring 1, a limiting well ring 2, and a rotary asphalt paving mechanism. The concrete adjustment ring 1 is fixed to the well seat after leveling. The upper end of the concrete adjustment ring 1 is trumpet-shaped, and a positioning slot is provided on the inner ring surface of the concrete adjustment ring 1. The limiting well ring 2 includes an integrally formed first ring body 21 and a second ring body 22. The second ring body 22 is located below the first ring body 21, and the outer diameter of the second ring body 22 is smaller than the outer diameter of the first ring body 21. When the limiting well ring 2 is inserted into the concrete adjustment ring 1, the second ring body 22 needs to be inserted into the concrete adjustment ring 1. The transition section between the first ring body 21 and the second ring body 22 is clamped at the upper end of the concrete adjustment ring 1. At the same time, a positioning block 23 is fixed on the outer wall of the second ring body 22. By inserting the positioning block 23 into the positioning slot, the concrete adjustment ring 1 and the limiting well ring 2 are positioned to prevent the limiting well ring 2 from rotating.

[0029] In order to be able to set up the rotary asphalt paving mechanism on the limiting well ring 2 so that it can automatically carry out asphalt filling and vibration compaction processes around the trench excavated around the limiting well ring 2, a support seat 3, a first fixing mechanism and a second fixing mechanism are also included.

[0030] Among them, the support seat 3 is cylindrical, and the rotary asphalt paving mechanism is arranged on the top of the support seat 3. The cylindrical support seat 3 is convenient for the rotation of the rotary asphalt paving mechanism. A lifting ear 31 is fixed on the top of the support seat 3. The lifting ear 31 can facilitate the transportation of the support seat 3 and the structural components connected to the support seat 3, so that during the asphalt paving process, the support seat 3 is placed on the top of the limiting well ring 2. The diameter of the support seat 3 is larger than the inner diameter of the limiting well ring 2 and smaller than the outer diameter of the limiting well ring 2. Such an arrangement can not only prevent the support seat 3 from falling into the limiting well ring 2 after installation, but also avoid the problem of difficulty in filling and compacting asphalt on the edge of the limiting well ring 2 after the support seat 3 protrudes out of the limiting well ring 2.

[0031] Among them, the first fixing mechanism includes multiple groups of abutment components and synchronous telescopic drive components, and the multiple groups of abutment components are arranged around the bottom of the support seat 3. The abutment components include a connecting rod 41, a guide sleeve 42, a sliding rod 43 and an abutment portion 44; one end of the connecting rod 41 is fixed to the bottom of the support seat 3, and the other end of the connecting rod 41 extends to the bottom of the limiting well ring 2; the guide sleeve 42 is horizontally fixed to the other end of the connecting rod 41; the sliding rod 43 is slidably connected in the guide sleeve 42; the abutment portion 44 is fixed on the side wall of the sliding rod 43 facing the concrete adjustment ring 1; the synchronous telescopic drive component has multiple telescopic ends, and each telescopic end is respectively connected to each sliding rod 43, which is used to drive multiple sliding rods 43 to slide synchronously in the guide sleeve 42, and use the abutment portion 44 to abut the inner wall of the concrete adjustment ring 1.

[0032] When the support seat 3 can be fixed by the first fixing mechanism, the synchronous telescopic drive assembly is used to drive multiple slide rods 43 to move synchronously along the guide sleeve 42, so that each abutment portion 44 abuts against the inner wall of the concrete adjustment ring 1 at the same time, realizing a concentric positioning and clamping process, so that the center of the support seat 3 and the limiting well ring 2 and the concrete adjustment ring 1 are located on the same axis, and the support seat 3 and the limiting well ring 2 can be automatically aligned without adjustment, thereby ensuring that the rotary asphalt paving mechanism can carry out the asphalt paving process on the groove pit around the limiting well ring 2.

[0033] Among them, the second fixing mechanism includes multiple groups of hook structures arranged around the inner side of the limiting well ring 2, and the hook structure includes a buckle seat 51, a telescopic assembly 52 and a hanging plate 53; the buckle seat 51 includes two side plates and a bottom plate fixed between the two side plates, and the two side plates are fixed to the inner wall of the limiting well ring 2; the telescopic assembly 52 is arranged at the top of the sliding rod 43 and is located on the outside of the connecting rod 41. The telescopic assembly 52 has a vertically arranged moving end, and the moving end extends to the top of the bottom plate and is connected to the bottom of the hanging plate 53.

[0034] Taking into account that the rotary asphalt paving mechanism adopts a rotating manner to fill the grooves around the limiting well ring 2 and in the process of vibration compaction, the reaction generated by the rotation is transmitted to the abutment part 44 through the support seat 3, which will cause the abutment part 44 to deflect, resulting in unstable clamping. At the same time, the reaction force generated by the vibration during the vibration compaction process is easily transmitted to the limiting well ring 2 through the support seat 3, causing the limiting well ring 2 to shake, thereby causing part of the asphalt to enter the gap between the limiting well ring 2 and the concrete adjustment ring 1, causing the limiting well ring 2 to deviate, affecting the flatness. Therefore, the second fixing mechanism can be used to enable the telescopic component 52 to drive the hanging plate 53 to follow The sliding rod 43 moves horizontally, so that the hanging plate 53 extends between the two side plates of the snap-fit ​​seat 51, and the two side plates are used to form a horizontal limit for the hanging plate 53, thereby preventing the abutment portion 44 from rotating. When the hanging plate 53 moves to above the bottom plate in the snap-fit ​​seat 51, the telescopic assembly 52 is used to drive the bottom plate to move downward and buckle on the bottom plate. This not only forms a vertical limit for the limiting well ring 2 to prevent it from shaking, but also enables the second fixing mechanism to cooperate with the first fixing mechanism to form a locking limit for the support seat 3 and the limiting well ring 2 during the asphalt rotary filling and vibration compaction process to prevent rotation and shaking.

[0035] After paving is completed, the support seat 3 and the various structural components fixed on the support seat 3 are lifted out from the limiting well ring 2, and then the limiting well ring 2 is pulled out, and finally the manhole cover is inserted into the space of the limiting well ring 2 and connected to the manhole seat, and finally the asphalt paved road surface near the manhole cover is compacted and leveled using a roller.

[0036] As a specific implementation of a synchronous telescopic drive component, the synchronous telescopic drive component in this embodiment includes a hydraulic cylinder 61, a screw rod 62, a turntable 63 and a plurality of pins 64; the cylinder body of the hydraulic cylinder 61 is fixed at the bottom center of the support seat 3; one end of the screw rod 62 is fixed to the piston rod end of the hydraulic cylinder 61; a screw hole is provided in the middle of the turntable 63, and is connected to the screw rod 62 through the screw hole and the thread, the circumferential side wall of the turntable 63 is rotatably connected to a plurality of connecting rods 41, and a plurality of arc-shaped guide slots 631 are opened on the top of the turntable 63 around its axis; a plurality of pins 64 are respectively slidably connected in the plurality of arc-shaped guide slots 631, and one end of each pin 64 is fixed to each sliding rod 43.

[0037] In this embodiment, when the synchronous telescopic drive assembly drives each slide rod 43 to move synchronously and telescopically, the hydraulic cylinder 61 drives the screw rod 62 to move vertically downward. During the movement of the screw rod 62, the thread of the screw hole set in the middle of the turntable 63 will be squeezed. Since the circumferential side wall of the turntable 63 is rotatably connected with multiple connecting rods 41, the linear motion of the screw rod 62 will be converted into the rotational motion of the turntable 63, thereby driving the turntable 63 to rotate. Since the slide rod 43 is restricted by the guide sleeve 42, the slide rod 43 can only move along the length direction of the guide sleeve 42. Therefore, as the turntable 63 rotates, the arc-shaped guide groove 631 is used to squeeze the pin shaft 64 and push the slide rod 43 and the abutment part 44 to move, thereby driving each connecting rod 41 to move synchronously and telescopically for concentric positioning, clamping and fixing.

[0038] Among them, one end of each pin shaft 64 facing away from the slide rod 43 extends to the top of the arc-shaped guide groove 631 to connect with a limit piece 65. The limit piece 65 can be threadedly connected to the pin shaft 64 by a limit nut, or can be fixedly sleeved on the pin shaft 64 by a limit block. The size of the limit nut and the size of the limit block are larger than the width of the arc-shaped guide groove 631, so that the limit piece 65 is supported on the top of the turntable 63. The purpose of setting the limit piece 65 is to take into account that the distance between the connecting rod 41 and one end of the pin shaft 64 and the guide sleeve 42 is far, which is easy to cause deformation. The existence of the limit piece 65 can position the vertical height of the pin shaft 64 and the connecting rod 41 to ensure that the connecting rod 41 always remains horizontal during movement.

[0039] As an optimization scheme of the above embodiment, the telescopic assembly 52 in this embodiment includes an elastic rod, a pressure rod 524 and a pressure plate 525; the elastic rod includes an outer tube 521, an inner rod 522 and a spring 523, the outer tube 521 is fixed to the top of the sliding rod 43, one end of the inner rod 522 is slidably passed through the outer tube 521, the other end of the inner rod 522 is fixed to the bottom of the hanging plate 53, and the spring 523 is connected between the inner rod 522 and the sliding rod 43; one end of the pressure rod 524 is fixed to the side wall of the inner rod 522, and the other end of the pressure rod 524 passes through the strip groove 411 vertically opened on the connecting rod 41 and extends to the inner side of the connecting rod 41; the pressure plate 525 is fixed on the piston rod end of the hydraulic cylinder 61.

[0040] In this embodiment, when the telescopic component 52 drives the pressure plate 525 to telescope and move, it is driven synchronously by the hydraulic cylinder 61. When the hydraulic cylinder 61 drives the screw rod 62 to descend to rotate the turntable 63, the pressure plate 525 is synchronously driven to descend. Since the rotation of the turntable 63 will drive the sliding rod 43 to move horizontally, the movement of the sliding rod 43 will drive the elastic rod to move horizontally as a whole. As the pressure plate 525 descends, it will gradually contact and press down the pressure rod 524. After the pressure rod 524 is compressed, it drives the inner rod 522 to move downward and contract the spring 523. During the descent of the inner rod 522, it drives the pressure plate 525 to move synchronously until the pressure plate 525 contacts the top of the bottom plate for locking and positioning. At the same time, the sliding rod 43 also drives the abutment part 44 to abut against the inner wall of the concrete adjusting ring 1 for clamping and positioning.

[0041] Among them, an annular groove is opened on the circumferential side wall of the turntable 63, and a bearing 66 is arranged in the annular groove. The inner ring surface of the bearing 66 is fixed to the groove wall of the annular groove, and the outer ring surface of the bearing 66 is fixed to multiple connecting rods 41. The setting of the bearing 66 can reduce the resistance, so that the turntable 63 can be more easily squeezed by the screw rod 62 to rotate.

[0042] In another embodiment of the present invention, a sliding guide assembly is provided at the top of the hanging plate 53, and the sliding guide assembly includes a guide groove 71, a guide slider 72 and a slide 73. The guide groove 71 is opened at the bottom of the support seat 3, and the guide slider 72 is slidably connected in the guide groove 71. A groove is opened at the bottom of the guide slider 72, and one end of the slide 73 is slidably connected in the groove, and the other end of the slide 73 is fixed to the top of the hanging plate 53.

[0043] In order to provide vertical support force for the guide slider 72 and prevent the guide slider 72 from detaching from the guide slot 71, the shape of the guide slider 72 is dovetail-shaped or T-shaped, and the shape of the guide slot 71 matches the shape of the guide slider 72.

[0044] Specifically, in order to increase the contact area with the inner wall of the limiting well ring 2, the abutment portion 44 is an arc-shaped abutment plate, which is coaxially arranged with the limiting well ring 2. The inner plate surface of the arc-shaped abutment plate is fixed to the end of the slide rod 43. The setting of the arc-shaped abutment plate can fully fit with the inner wall of the limiting well ring 2, thereby improving the clamping and fixing ability.

[0045] Specifically, as an optional implementation scheme of the rotary asphalt paving mechanism, the rotary asphalt paving mechanism in this embodiment includes a motor 81, a rotating frame 82, two linear motion mechanisms 83, an asphalt storage hopper 84 and a compacting assembly 85. The motor 81 is fixed on the top of the support base 3, and the output shaft of the motor 81 is fixed to the bottom center of the rotating frame 82. The two linear motion mechanisms 83 are respectively arranged on both sides of the top of the rotating frame 82. The side wall of the asphalt storage hopper 84 is connected to the moving end of one of the linear motion mechanisms 83. The compacting assembly 85 includes a connecting seat and a vibrating tamping plate fixed to the bottom of the connecting seat. The connecting seat is connected to one end of one of the linear motion mechanisms 83. The linear motion mechanism 83 can adopt a structure with linear motion such as a screw nut guide rail or an electric cylinder. The distance between the asphalt storage hopper 84 and the compacting assembly 85 is adjusted by the linear motion mechanism 83. The bottom of the asphalt storage hopper 84 is provided with a discharge port, and the discharge port is provided with a discharge control valve.

[0046] In this embodiment, when asphalt is paved in the trench around the wellhead, the motor 81 is provided to drive the rotating frame 82 to rotate, and the rotating frame 82 drives the asphalt storage hopper 84 and the compaction assembly 85 to rotate synchronously around the wellhead. The amount of asphalt released from the asphalt storage hopper 84 is controlled by the provided discharge control valve, and the released asphalt is vibrated and compacted by the vibrating tamping plate. During the rotating paving process, the position of the paved asphalt is adjusted by synchronously controlling the telescopic movement of the two linear moving mechanisms 83 and adjusting the positions of the asphalt storage hopper 84 and the compaction assembly 85 so that they are moved away from or close to each other, so that the position is kept flush with the road surface after layered paving.

[0047] Among them, in order to support the bottom of the rotating frame 82 when the motor 81 drives the rotating frame 82 to rotate, support rods 91 are fixed on both sides of the bottom of the rotating frame 82, and a mounting groove is opened at the bottom of the support rod 91, and a ball 92 is connected to the mounting groove, and an annular groove 32 is opened on the top of the support seat 3, so that the bottom of the support rod 91 is inserted into the annular groove 32 and contacts the bottom of the annular groove 32 through the ball 92. Through the above arrangement, when the rotating frame 82 rotates, the ball 92 is used to support the bottom of the support rod 91 and reduce friction resistance.

[0048] The above disclosures are only several preferred specific embodiments of the present invention. However, the embodiments of the present invention are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the scope of protection of the present invention.
