Description

Technical Field

[0001] The utility model relates to the technical field of road paving, in particular to an asphalt road surface compactor. Background Art

[0002] Asphalt pavement refers to various types of pavement paved with road asphalt materials mixed into mineral materials. The asphalt binder improves the ability of paving aggregate to resist damage to the road surface caused by traffic and natural factors, making the road surface smooth, dust-free, waterproof and durable. After paving the asphalt on the road surface, it is very necessary to compact the asphalt pavement.

[0003] For the compaction work of narrow asphalt pavement, an engineering vehicle equipped with a small compaction equipment is usually used for the compaction work of the asphalt pavement. The working principle is usually to use a motor to drive an eccentric wheel to achieve vibration impact compaction work. The vibration caused by the rotation of the eccentric wheel will often drive the entire structure to vibrate. Long-term vibration will inevitably cause mechanical damage to various components, thereby limiting the service life of the entire structure and leading to a higher failure rate. Utility Model Content

[0004] The purpose of the utility model is to provide an asphalt pavement compactor to solve the problems raised in the above background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] Furthermore, the vibration structure includes a motor output shaft, both ends of the motor output shaft are rotatably connected with a driving motor, and a motor seat is fixedly installed on the upper surface of the driving motor.

[0008] Furthermore, a triangular wheel frame is fixedly installed in the middle of the motor output shaft, an impact wheel is rotatably installed at the end point of the triangular wheel frame, the impact wheel is movably connected to the impacted wheel, the impacted wheel is rotatably installed on the top of the support frame, and the support frame is fixedly installed on the upper end of the transmission seat.

[0011] Furthermore, the connection blocks are fixedly installed at the four corners of the base plate.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. The connecting seat is connected to the working end of the engineering vehicle. Based on the base plate, the vibration base plate is given the effect of free up and down movement within a certain range through the hinged frame. The vibration structure is used to continuously knock the vibration base plate, so that the vibration base plate can continuously impact downward. Then, four sets of sliding sleeve connecting rods, telescopic rods and internal return springs are used to give the vibration base plate the effect of returning after being knocked downward by the vibration structure, thereby achieving the effect of repeated vibration and compaction. At the same time, the vibration is relatively isolated at the vibration base plate and the lower end of the connecting rod to prevent other structures from being continuously subjected to vibration during work, thereby reducing the failure rate.

[0014] 2. Based on the base plate, through the support of connecting blocks and struts, the supporting feet can be independent of the vibration base plate, tamping plate and other tamping components to provide auxiliary support for the overall structure. At the same time, by adjusting the clamping position between the connecting block and the strut, replacing different locking slots, and adjusting the actual support height of the strut, the actual impact downward distance of the vibration base plate and the tamping plate can be limited.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-4 In the embodiment of the utility model, an asphalt pavement compactor includes a compacting body 1, a vibration structure 2 is fixedly installed inside the compacting body 1, and support legs 3 are clamped on both sides of the compacting body 1. The compacting body 1 includes a base plate 101, a connecting seat 102 is fixedly installed on the upper surface of the base plate 101, and hinged frames 103 are hinged on the front and rear edges of the bottom of the base plate 101. The lower end of the hinged frame 103 is hinged to the front and rear sides of the upper surface of the vibration base plate 104. A compacting plate 105 is fixedly installed on the bottom of the vibration base plate 104, and connecting rods 106 are fixedly installed at the four corners of the upper surface of the compacting plate 105. Telescopic rods 107 are fixedly installed at the four corners of the bottom side of the base plate 101. The connecting rod 106 and the telescopic rod 107 are slidably connected to each other, and a return spring 108 is wound around the side surface of the telescopic rod 107.

[0022] Specifically, the connecting seat 102 is connected to the working end of the engineering vehicle, and the base plate 101 is used as the basis. The articulated frame 103 allows the vibration base plate 104 to move freely up and down within a certain range. The vibration structure 2 is used to continuously knock the vibration base plate 104, so that the vibration base plate 104 can continuously impact downward, and then four groups of sliding sleeve connecting rods 106, telescopic rods 107 and internal return springs 108 allow the vibration base plate 104 to return to its original position after being knocked downward by the vibration structure 2, thereby achieving the effect of repeated vibration and compaction. At the same time, the vibration is relatively isolated at the lower ends of the vibration base plate 104 and the connecting rod 106 to prevent other structures from being continuously subjected to vibration during operation, thereby reducing the failure rate. The compaction plate 105 is in direct contact with the asphalt pavement to expand the compaction area.

[0023] like Figure 3As shown, in this embodiment, the vibration structure 2 includes a motor output shaft 201, and the two ends of the motor output shaft 201 are rotatably connected with a driving motor 202, and a motor seat 203 is fixedly installed on the upper surface of the driving motor 202; a triangular wheel frame 204 is fixedly installed in the middle of the motor output shaft 201, and an impact wheel 205 is rotatably installed at the end point of the triangular wheel frame 204, and the impact wheel 205 is movably connected with the impact wheel 206, and the impact wheel 206 is rotatably installed on the top of the support frame 207, and the support frame 207 is fixedly installed on the upper end of the transmission seat 208. The motor output shaft 201 is synchronously driven by two groups of driving motors 202 to provide stronger power; two groups of motor seats 203 are fixedly installed on the two side edges of the bottom of the substrate 101, and the transmission seat 208 is fixedly installed in the middle of the upper surface of the vibration base plate 104.

[0024] During specific implementation, the triangular wheel frame 204 is rotated by the motor output shaft 201, so that each impact wheel 205 continuously presses the impacted wheel 206, generating a downward impact force, which is then transmitted to the transmission seat 208 by the support frame 207, and finally transmitted to the vibration base plate 104. The triangular wheel frame 204 is used to replace the traditional eccentric wheel structure to generate vibration, thereby preventing the entire structure from vibrating following the rotation of the eccentric wheel.

[0025] Embodiment 2

[0026] On the basis of the first embodiment, in order to compensate for the relatively fixed up and down moving distances of the vibration base plate 104 and the compaction plate 105 in the first embodiment, the support of the engineering vehicle completely relies on the connection seat 102, and the compaction strength is less adjustable.

[0027] like Figure 4 As shown, in this embodiment, the supporting bracket 3 includes two supporting foot strips 301, and support rods 302 are fixedly installed at both ends of the upper surface of the supporting foot strips 301. Locking slots 303 are inserted in both sides of the upper ends of the support rods 302. The support rods 302 are inserted into the connecting blocks 304, and connecting pins 305 are inserted into the locking slots 303 and one side of the connecting blocks 304; the connecting blocks 304 are fixedly installed at the four corners of the base plate 101.

[0028] During specific implementation, based on the base plate 101, through the support of the connecting block 304 and the support rod 302, the supporting foot bar 301 can be independent of the vibration base plate 104, the tamping plate 105 and other tamping components, to provide auxiliary support for the overall structure. At the same time, by adjusting the clamping position between the connecting block 304 and the support rod 302 and replacing different locking slots 303, the actual supporting height of the support rod 302 can be adjusted, thereby limiting the actual impact downward distance of the vibration base plate 104 and the tamping plate 105.

[0029] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.

[0030] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
