Description

Technical Field

[0001] This utility model relates to the field of asphalt pavement quality testing technology, specifically to an asphalt paving temperature monitoring device. Background Technology

[0002] Asphalt pavement refers to various types of pavement constructed by mixing road asphalt materials with mineral materials. It is one of the most widely used high-grade pavements in road construction. During the asphalt pavement paving process, temperature monitoring and early warning devices are required to ensure that the asphalt insulation remains within a stable range, thereby ensuring the paving effect of the asphalt pavement.

[0003] During asphalt paving, excessively high paving temperatures can cause the mixture to soften, reducing the road's load-bearing capacity. Conversely, excessively low paving temperatures can cause the mixture to cool and solidify before it is fully compacted, making it impossible to lay additional layers and preventing the road from achieving the required compaction degree. This negatively impacts the road's strength and waterproofing performance. Therefore, both excessively high and low temperatures negatively affect the quality of asphalt roads.

[0004] Existing asphalt paving temperature monitoring devices use screw drives to achieve the reciprocating motion of the temperature measuring device. However, this drive method has a slow response speed, and the temperature monitoring of the asphalt pavement point by point results in too large an interval between points, making it impossible to fully and accurately reflect the quality of asphalt paving.

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0036] Asphalt roads will develop various defects during later use, causing varying degrees of damage to the road surface, such as loosening, potholes, and cracks. In addition to the quality of the asphalt itself, the main cause of these defects is the substandard quality control of asphalt paving.

[0037] To address the aforementioned technical problems, this application provides an asphalt paving temperature monitoring device, which aims to increase the frequency of temperature collection on the asphalt pavement during the asphalt paving process, ensuring that temperature field monitoring can be carried out during paving, so that identified temperature defects can be addressed as early as possible.

[0038] The technical solutions of the embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0039] like Figure 1 and Figure 2 As shown in the figure, an embodiment of the present invention provides an asphalt paving temperature monitoring device, comprising:

[0040] The mobile platform 1 has a chamber 10 with a bottom opening, and a slide 11 extending along the length of the mobile platform 1 is provided in the chamber 10.

[0041] Temperature measuring component 2 is slidably engaged with the slide rail 11, with the detection end of the temperature measuring component 2 facing the ground;

[0042] The transmission assembly 3, disposed within the chamber 10, includes a motor 31, a turntable 32, a rotating shaft 33, and a transmission rod 34. The motor 31 is connected to the turntable 32, and the axis of the turntable 32 is perpendicular to the axis of the slide rail 11. The rotating shaft 33 is rotatably mounted on the turntable 32. The first end of the transmission rod 34 is hinged to the temperature measuring assembly 2, and the second end is connected to the rotating shaft 33.

[0043] The mobile platform 1 can be an electric tricycle, a small truck, a cart, or any tool capable of moving freely on the asphalt pavement. In this embodiment, the mobile platform 1 maintains the same forward speed as the paver, and is located behind the paver to ensure that the temperature field of the current asphalt pavement section can be monitored as soon as the asphalt paving is completed. In practical implementation, the mobile platform 1 can be attached to the asphalt paver, and the asphalt paver can drive the mobile platform 1 to move.

[0044] The asphalt paving temperature monitoring device is connected to an external power source or a portable power source such as a lithium battery. After the power is turned on, the motor 31 drives the turntable 32 to rotate around the rotation axis of the motor 31. The turntable 32 drives the transmission rod 34 to push and pull the temperature measuring component 2 back and forth. The temperature measuring component 2 slides freely on the slide rail 11, so that it can move closer to and further away from the turntable 32 at a predetermined moving distance to achieve back and forth movement. During the movement, the temperature of the asphalt pavement is collected according to the preset interval time.

[0045] The distance between the rotating shaft of motor 31 and the rotating shaft 33 determines the measuring stroke of temperature measuring component 2. In practical applications, it can be freely set according to the asphalt pavement to be paved, and there is no single limitation here.

[0046] To facilitate those skilled in the art in implementing the technical solution of this utility model, the following description assumes that the rotation speed of the motor 31 is 30 rpm, the moving stroke of the temperature measuring component 2 is 1 m, and the temperature monitoring time interval of the temperature measuring component 2 is 0.1 s. The rotation speed of the motor 31 is controlled at 30 rpm and the moving stroke of the temperature measuring component 2 is 1 meter, meaning that the temperature measuring component 2 can complete one cycle in 2 seconds. At this time, the moving path of the temperature measuring component 2 is zigzag, and it is set to collect data once every 0.1 seconds, that is, 10 points can be collected on each straight line, with each point spaced 10 cm apart.

[0047] Compared with the prior art, when adopting the technical solution of this utility model, the motor 31 drives the turntable 32 to rotate, which drives the transmission rod 34 to push and pull the temperature measuring component 2 back and forth. This allows the temperature measuring component 2 to quickly collect a denser temperature field on the asphalt pavement, which can truly and comprehensively reflect the quality of asphalt paving. It is convenient to identify the existing temperature defects and intervene as early as possible to avoid quality problems such as looseness, cracks, potholes, and ruts in the asphalt pavement during use due to substandard temperature.

[0048] The temperature measuring component 2 of the above-mentioned asphalt paving temperature monitoring device includes a sliding plate 21, a mounting plate 22 and a thermometer 23. The sliding plate 21 is slidably engaged with the slide rail 11, the mounting plate 22 is connected to the sliding plate 21, and the bottom of the mounting plate 22 is connected to the thermometer 23.

[0049] Furthermore, such as Figure 3As shown, the slide rail 11 of the above-mentioned asphalt paving temperature monitoring device includes a slide rail 111, a slider 112, a fixed shaft 113, and several damping components 114. The end of the sliding plate 21 is provided with a groove, the slider 112 is housed in the groove, and is rotatably connected to the sliding plate 21 through the fixed shaft 113. Several damping components 114 are sleeved on both ends of the fixed shaft 113. Each damping component 114 includes a pad and a damping washer stacked in sequence. The fixed shaft 113 and the sliding plate 21 can rotate relative to each other to compress the damping washer.

[0050] Specifically, the fixed base is fitted with several damping components 114. Through the pads and damping washers in the damping components 114, when a group of damping components 114 is rotated under force, several damping components 114 rotate synchronously. The damping washers in each damping component 114 move relative to the pads to generate friction, ensuring that the sliding plate 21 can be fixed at various angles. This greatly facilitates the operator to adjust the angle of the sliding plate and the moving area of ​​the temperature measuring instrument 23, thereby adapting to various emergencies at the paving site.

[0051] In another feasible solution, the slide rail 111 can also be a slide rod. When a slide rod is used, a circular hole is provided in the slider 112, and an annular groove for placing a ball is provided in the circular hole. The slide rod passes through the circular hole and contacts and abuts against the ball. More specifically, two annular grooves are provided on the circular hole to improve the stability between the sliding plate 21 and the slide rod, and to prevent the sliding plate 21 from shaking and affecting the transmission stroke of the transmission rod 34.

[0052] like Figure 4 As shown, in order to improve the adaptability of the mobile platform 1 to the width of the asphalt pavement, the turntable 32 of the asphalt paving temperature monitoring device is provided with a plurality of annular inner teeth 320 arranged side by side. The plurality of annular inner teeth 320 are arranged radially along the turntable 32. The rotating shaft of the motor 31 is provided with a first annular outer tooth, the size of which is adapted to the annular inner teeth 320.

[0053] Furthermore, the rotating shaft 33 of the aforementioned asphalt paving temperature monitoring device is rotatably fitted with a second annular external tooth, the size of which is adapted to the annular internal tooth 320.

[0054] Both the rotating shaft and the rotating shaft 33 of the motor can mesh with the annular internal gear 320. By adjusting the distance between the first and second annular external gears through the annular internal gear 320, the moving distance of the temperature measuring component 2 can be adjusted. Both the rotating shaft and the rotating shaft 33 of the motor 31 are detachably connected to the turntable 32. Specifically, after the rotating shaft and the rotating shaft 33 pass through the annular internal gear 320 of the turntable 32, they are fixed by means of pins.

[0055] In order to quickly replace turntables 32 of different diameters within the mobile platform 1, the mobile platform 1 of the asphalt paving temperature monitoring device includes a base 12 and a housing 13. The base 12 has an opening extending through its own thickness direction, and the housing 13 covers the base 12.

[0056] The bottom of the base 12 is provided with a caster wheel assembly 4;

[0057] The slide 11, the temperature measuring component 2, and the transmission component 3 are all located inside the housing 13.

[0058] Furthermore, the above-mentioned asphalt paving temperature monitoring device also includes a control system 5, a buzzer 6, and a controller 7. The control system 5 is located inside the housing 13, the buzzer 6 is located on the top of the housing 13, and the controller 7 is located on the outer surface of the housing 13. The temperature measuring component 2, the motor 31, the buzzer 6, and the controller 7 are all connected to the control system 5.

[0059] Furthermore, the asphalt paving temperature monitoring device universal wheel assembly 4 includes a sleeve 41, a spring 42, a buffer rod 43, and a universal wheel body 44. The spring 42 is disposed inside the sleeve 41, the spring 42 is connected to the buffer rod 43, and the buffer rod 43 is connected to the universal wheel body 44.

[0060] like Figure 5 As shown, in order to enable the mobile platform 1 to move synchronously with the asphalt paver, the asphalt paving temperature monitoring device also includes a clamping mechanism 8 for fixing the mobile platform 1 to the asphalt paver. The clamping mechanism 8 includes a plate 81, a screw 82, and a clamping plate 83. The plate 81 is U-shaped and is connected to one side of the mobile platform 1. The top of the plate 81 is provided with a screw hole for the screw 82 to be screwed into. The screw 82 passes through the screw hole and is connected to the clamping plate 83.

[0061] Furthermore, the head of the screw 82 of the aforementioned asphalt paving temperature monitoring device is covered with a rubber layer, and the outer surface of the rubber layer is provided with anti-slip grooves.

[0062] Specifically, based on the asphalt paving temperature monitoring device in the embodiments of this application, this application also provides application examples of the asphalt paving temperature monitoring device.

[0063] 1. Place the device behind the asphalt paver, with the fixed part of the asphalt paver located between the clamping plate 83 and the plate 81. The operator rotates the screw 82 clockwise, causing the screw 82 to move downward through the thread. The screw 82 drives the clamping plate 83 to move, so that the clamping plate 83 fits tightly against the asphalt paver. The asphalt paver can then be clamped by the clamping plate 83 and the plate 81, thus fixing the device on the asphalt paver.

[0064] 2. When the device is connected to the power supply, the asphalt paver moves the device together when laying asphalt. The operator can start the control system 5 and the thermometer 23 through the controller 7. The thermometer 23 monitors the temperature of the asphalt pavement in real time and transmits the monitored temperature information to the control system 5.

[0065] 3. The staff can start the motor 31 through the controller 7, so that the motor 31 drives the turntable 32 to rotate at a constant speed through the rotating shaft 33. The turntable 32 drives the transmission rod 34 to rotate, and the temperature measuring component 2 moves back and forth on the asphalt road surface, so that the temperature measuring instrument 2313 can continuously monitor the temperature at different locations on the asphalt road surface.

[0066] When the asphalt temperature is lower or higher than the preset threshold of the control system 5, the control system 5 shuts off the motor 31, and the temperature measuring instrument 23 stops moving, so that the temperature measuring instrument 23 is located at the abnormal asphalt temperature position.

[0067] The control system 5 simultaneously activates the buzzer 6, which emits an audible alert to help staff quickly understand any abnormal asphalt temperature conditions.

[0068] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0069] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
