An asphalt pavement corner compactor

Abstract

This utility model discloses an asphalt pavement corner compactor, specifically relating to the field of asphalt compaction technology. It includes a movable support platform with a counterweight electrical box at its upper center. Limiting protrusions are located on the outer end face of the movable support platform and the upper side of the counterweight electrical box. A drive motor is located at the upper center of the limiting protrusion, and limiting sliding rods are located on both sides of the lower end of the limiting protrusion. In actual use, with the corresponding arrangement of the compaction plate, vibrating motor, limiting baffle, limiting support plate, adjusting screw, screw slider, and support spring, when the screw slider rises in height, it is supported by the limiting support plate through the support spring. The support spring, in turn, pushes against the support slider through the limiting support plate, allowing for smooth lifting and lowering, thus keeping the support slider in a suspended state and increasing the stability of the support slider's lifting and lowering control.

Description

Technical Field

[0001] This utility model relates to the field of asphalt compaction technology, and more specifically, to an asphalt pavement corner compactor. Background Technology

[0002] The existing asphalt pavement construction methods mostly adopt the rolling compaction method. The rolling compaction method usually uses large compaction machinery to compact the asphalt aggregate. Large machinery has high compaction efficiency and good compaction effect, but when it comes to the junction of the curb and the corner of the roadside, large machinery is difficult to handle, and small equipment is needed to compact the corner of the asphalt pavement. For example, patent CN221480481U discloses an asphalt pavement corner compactor, including a frame. A vibration mechanism is fixedly installed on the outer wall of the top of the frame. The vibration mechanism serves as the driving component of the device, providing power for its movement. A vibrating plate connected to the vibration mechanism is provided below the frame. The continuous vibration of the vibrating plate on the asphalt pavement achieves the effect of compacting the asphalt pavement. The vibrating plate and the frame are elastically connected. The elastic connection limits the movement of the vibrating plate but does not separate it from the frame. This elastic connection can be achieved by combining a spring and a guide rod.

[0003] When the above-mentioned device is working, it improves the compaction effect of asphalt pavement at the edges and corners. The photoelectric sensor used in conjunction with the servo motor can automatically adjust the adjustment components, reducing the tediousness of manual control. However, when the vibration mechanism is working, the vibration generated will be transmitted to the frame, increasing the difficulty of operation for the staff. Utility Model Content

[0022] This utility model provides an asphalt pavement corner compactor, such as... Figure 1 and Figure 2 As shown, it includes a movable support platform 1, a counterweight electrical box 4 is provided in the middle of the upper end of the movable support platform 1, and a limiting protrusion 7 is provided on the outer end face of the movable support platform 1 and the upper side of the outer end face of the counterweight electrical box 4. The upper end of the limiting protrusion 7 is provided with a drive motor 12, and the lower end of the limiting protrusion 7 is provided with limiting slide rods 9 on both sides. The outer end face of the counterweight box 4 is provided with multiple limiting baffles 11 on the lower side of the limiting protrusion 7. The counterweight box 4 has a support slider 8 on its outer side, the lower end of the movable support platform 1 has a movable wheel 2, and the upper side of the movable support platform 1 has a movable handle 3, which can drive the movable support platform 1 to move, increasing the convenience of operation for the staff. The upper side of the movable handle 3 has a control box 5. The upper end of the control box 5 is provided with a control button 6. The output shaft of the drive motor 12 passes through the end face of the limiting protrusion 7 and extends to its lower end. The operator can work through the control button 6 and the control box 5. The control box 5 will drive the drive motor 12 to work. The output shaft of the drive motor 12 is provided with an adjusting screw 10 on the lower side of the limiting protrusion 7. When the drive motor 12 is working, it will drive the adjusting screw 10 to rotate. The counterweight box 4 and the control box 5 are electrically connected. The drive motor 12 and the control box 5 are electrically connected.

[0023] like Figure 3 and Figure 4 As shown, the upper and lower sides of the inner end face of the support slider 8 are provided with limiting support plates 18, and the two second circular sliding holes 13 are provided with a lead screw slider 14. When the adjusting lead screw 10 is rotated, it will drive the lead screw slider 14 to rise and fall in height. When the lead screw slider 14 rises and falls in height, the limiting baffle 11 will limit the two sides of the lead screw slider 14, thereby ensuring the stability of the lead screw slider 14 when rising and falling in height. Both ends of the lead screw slider 14 are provided with support springs 15. Vertical limiting blocks 16 are provided on both sides of the inner end face of the support slider 8. The end face of the vertical limiting block 16 is provided with a first circular sliding hole 17, and the end face of the limiting support plate 18 is provided with a second circular sliding hole 13. When the lead screw slider 14 is raised or lowered, the limiting support plate 18 will be supported by the support spring 15. The lower end of the support slider 8 is provided with a connecting plate 19, and a compaction plate 20 is provided on one side of the lower end of the connecting plate 19. A vibration motor 21 is provided in the middle of the upper end of the compaction plate 20. The operator can drive the vibration motor 21 to work through the control box 5. The vibration motor 21 will drive the compaction plate 20 to vibrate rapidly, thereby compacting the corners of the asphalt pavement through the compaction plate 20. The inner end face diameter of the limiting slider 9 in the top view direction is larger than the outer end face diameter of the first circular sliding hole 17 in the top view direction. The inner end faces of the two adjacent limiting baffles 11 are in contact with the outer end face of the lead screw slider 14, and the adjusting lead screw 10 is through the end face of the second circular sliding hole 13, the support spring 15 and the lead screw slider 14. The diameter of the outer end face of the adjusting screw 10 in the top view direction is smaller than the diameter of the inner end face of the second circular sliding hole 13 in the top view direction. The outer end face of the adjusting screw 10 is in contact with the inner end face of the through hole in the middle of the screw slider 14. When the vibration motor 21 is working, the force generated by the vibration will be transmitted to the support slider 8 through the connecting plate 19, which will make the stability of the operator's operation of the compaction equipment worse. The support spring 15 will reduce the effect of vibration force transmission.
