Description

Technical Field

[0001] This utility model belongs to the field of road construction, and specifically relates to an alarm device for controlling the edge compaction distance of a double-drum roller. Background Technology

[0002] During the asphalt paving process, the road needs to be compacted by a double-drum roller. During the initial compaction, intermediate compaction, final compaction, and detailed rolling processes, sometimes the driver will operate the double-drum roller too close to the curb for edge compaction, which can easily cause the steel wheel to come into contact with the curb, resulting in friction damage to the curb, such as chipping or breaking. Alternatively, the metal of the steel wheel may come into contact with the curb, leaving rust on the side of the curb that is difficult to clean and remains for a long time, affecting the overall aesthetics of the road. Summary of the Invention

[0003] The problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide an alarm device for controlling the edge compaction distance of a double-drum roller.

[0004] This invention is achieved through the following technical solution:

[0005] A double-drum roller edge compaction distance control alarm includes a support rod A, which is vertically fixed to the lower part of the frame between the two drums of the double-drum roller. The outer end of the support rod A is fixed to one end of a spring, and the other end of the spring is fixed to a support rod B. The outer end of the support rod B is fixed downward to a distance detector, and the outer end of the distance detector is in the same vertical plane as the outer surface of the drum. The distance detector is connected to an audible alarm. The support rod B has a vertical through hole and a horizontal through hole on the side near the distance detector. An elastic rope A passes through the vertical through hole, and the two ends of the elastic rope A are fixed to the frame on the upper and lower sides of the support rod A, respectively. An elastic rope B passes through the horizontal through hole, and the two ends of the elastic rope B are fixed to the frame on the left and right sides of the support rod A, respectively.

[0006] Preferably, the support rod A is symmetrically provided with bolts at the top and bottom and left and right, and nuts are connected to the bolts. The two ends of the elastic rope A and elastic rope B are respectively wrapped around the bolts and pressed by the nuts.

[0007] Preferably, the support rod A is symmetrically provided with hooks at the top and bottom and left and right, and both ends of the elastic pull rope A and elastic pull rope B are hung on the hooks.

[0008] Preferably, both the elastic rope A and the elastic rope B are rubber bands.

[0009] Preferably, the distance detector is wirelessly connected to the audible alarm.

[0010] Preferably, the audible alarm is installed in the cab of the double-drum roller.

[0011] This invention can effectively remind the driver to control the distance between the double-drum roller and the curb, protecting the curb from being scratched by the drum roller and avoiding damage to the curb during compaction. This invention has a simple structure, low cost, and high practicality. Attached Figure Description

[0013] Figure 2 This is an enlarged structural diagram of this embodiment;

[0014] Figure 3 This is a schematic diagram of the structure after removing elastic rope A and elastic rope B in this embodiment.

[0016] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of the present invention, but not all embodiments.

[0017] This embodiment includes a support rod A1, which can be made from a small square tube by cutting off a section of a discarded square tube. The support rod A1 is vertically fixed to the lower part of the frame between the two steel wheels 2 of the double-drum roller. The outer end of the support rod A1 is fixed to one end of a spring 3, and the other end of the spring 3 is fixed to one end of the support rod B4. The spring 3 is used to buffer the vibration of the double-drum roller during operation, and its length is approximately 1-2 cm. A distance detector 5 is fixed downwards at the outer end of the support rod B4. The outer end of the distance detector 5 is in the same vertical plane as the outer surface of the steel wheel 2, i.e., the outer end of the distance detector 5 is flush with the outer end of the steel wheel 2. The distance detector 5 measures the distance between the steel wheel 2 and the side of the curb stone; this distance is the distance between the steel wheel 2 and the side of the curb stone. The distance detector 5 is connected to a sound alarm (not shown in the attached diagram). The sound alarm can be installed on the support rod B4 or on the frame. In this embodiment, it is preferred that the sound alarm be installed in the cab of the double-drum roller. The distance detector 5 and the sound alarm are wirelessly connected. The distance detector 5 transmits the measured distance data to the audible alarm. When the distance data measured by the distance detector 5 is less than the set threshold, the audible alarm will sound, reminding the driver that the steel wheel 2 is too close to the curb. Upon hearing the alarm, the driver will adjust the distance between the steel wheel 2 and the curb accordingly. The threshold for the distance data measured by the distance detector 5 can be set according to actual conditions. Generally, this threshold can be set to 2cm, meaning that when the distance between the steel wheel 2 and the side of the curb is less than 2cm, the audible alarm will sound to remind the driver.

[0018] A vertical through hole 6 and a horizontal through hole 7 are respectively provided on the side of the support rod B4 near the distance detector 5. An elastic rope A8 passes through the vertical through hole 6. The elastic rope A8 can preferably be a rubber band with good elasticity. After passing through the vertical through hole 6, the two ends of the elastic rope A8 are respectively fixed to the frame on the upper and lower sides of the support rod A1. An elastic rope B9 passes through the horizontal through hole 7. The elastic rope B9 can also preferably be a rubber band. After passing through the horizontal through hole 7, the two ends of the elastic rope B9 are respectively fixed to the frame on the left and right sides of the support rod A1. There are several ways to fix the elastic pull ropes A8 and B9. Hooks can be symmetrically fixed to the upper and lower sides and the left and right sides of the frame of the support rod A1. The ends of the elastic pull ropes A8 and B9 are respectively hung on the corresponding hooks. In this embodiment, bolts 10 are symmetrically fixed to the upper and lower sides and the left and right sides of the frame of the support rod A1. Nuts 11 are connected to the bolts 10. The ends of the elastic pull ropes A8 and B9 can be wrapped around the corresponding bolts 10, and then the nuts 11 are tightened to press and fix the elastic pull ropes A8 and B9. The elastic pull ropes A8 and B9 pull the support rod B4 from four directions, thus working together with the spring 3 to counteract the vibration generated by the double-drum roller.

[0019] During construction, the driver operates a double-drum roller to compact asphalt around the curb. When the alarm sounds, the driver knows that the second drum is too close to the curb and adjusts its position accordingly to protect the curb from being scratched by the second drum.

[0020] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; those skilled in the art should understand that modifications can still be made to the technical solutions described in the above embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.
