Description

Technical Field

[0001] The utility model belongs to the technical field of intelligent road construction, and particularly relates to an auxiliary device for on-site installation of a temperature sensor. Background Technique

[0002] During the transportation of asphalt mixture, obvious temperature differences will occur due to uneven heat loss, further causing temperature segregation of the asphalt mixture. When paving the road surface with asphalt mixture with temperature segregation, the asphalt mixture with lower temperature cannot be effectively compacted, resulting in a higher void ratio and roughness of the road surface and reducing the compactness of the road surface. This will lead to structural damage of the road surface, shortened expected service life, and also affect driving safety and driving comfort. In order to pave a high-quality asphalt road surface and extend the service life and cycle of the road surface, it is necessary to reduce the temperature segregation of the asphalt mixture.

[0003] In actual transportation of asphalt mixture, different types and tonnages of dump trucks are usually used as transportation tools, and the dump trucks take corresponding heat preservation measures according to transportation requirements to prevent excessive heat loss of the asphalt mixture during transportation. During the process from mixing and loading to transporting to the construction site, the asphalt mixture is affected by many adverse factors such as wind speed, atmospheric temperature, transportation distance, and time, resulting in continuously changing temperature segregation phenomena among different parts of the asphalt mixture in the carriage. However, only qualitative analysis has been done on the temperature change during the whole transportation process, and there is no clear quantitative data to represent the whole temperature segregation change process. What can be achieved in traditional construction technology is that after the asphalt mixture is transported to the construction site, on-site technicians use a thermometer to manually detect the temperature of the mixture through the reserved temperature measurement holes on the side plate of the dump truck carriage to judge whether the current asphalt mixture meets the paving requirements. This method is not only time-consuming and laborious, but also cannot illustrate whether the whole truck of asphalt mixture meets the construction requirements through the temperature detection at a single point, let alone master the dynamic temperature change of the asphalt mixture during transportation.

[0004] The continuous development and improvement of intelligent road construction technologies have provided a new idea for studying the temperature changes of asphalt mixtures during transportation, that is, by installing temperature sensors at the parts where the heat loss of asphalt mixtures is severe on the side plates of the dump truck carriage to realize the process study of the temperature changes of asphalt mixtures. Compared with the traditional single temperature measurement method for asphalt mixtures, temperature measurement by sensors is not only faster, more efficient, and more accurate, but also can detect and feedback the temperature of the mixture in real time and dynamically without manual participation. However, due to the structural characteristics of the dump truck itself, there is no position or device on the carriage plate that can effectively install temperature sensors. If temperature sensors are blindly installed on the carriage plate, it may cause the temperature sensors to malfunction or be scratched and damaged during the loading and unloading of asphalt mixtures. During the transportation of asphalt mixtures by dump trucks, the temperature field of the asphalt mixtures will change in real time. In order to perform real-time temperature detection on the asphalt mixtures in the area with a large temperature difference on the side plates of the dump truck carriage, temperature sensors need to be installed on the side plates of the dump truck carriage. Since the carriage plate is thick, smooth, and in a high-temperature environment, there is a lack of a direct and effective installation method for temperature sensors. Therefore, the installation of temperature sensors requires the assistance of an auxiliary installation device. Utility Model Content

[0005] To solve the problem of effectively installing temperature sensors on the carriage plate, the present utility model provides an auxiliary device for on-site installation of temperature sensors, and realizes the temperature measurement purpose through its effective auxiliary installation of temperature sensors.

[0008] At the crossbeam at the top end of the inner bracket, a top temperature sensor installation hole I is provided corresponding to the bottom temperature sensor installation hole II, and a sealing rubber ring I is installed.

[0009] A sensor data line perforation is reserved at the top end of the inner bracket, and the temperature sensor data line can extend or be connected to the peripheral device interface after passing through the sensor data line perforation.

[0010] The upper part of the inner bracket is designed with a staggered structure, so that the whole inner bracket can be connected to the outer bracket through double-headed bolts and double-headed bolt fixing nuts after overlapping on the upper surface of the carriage plate.

[0011] A pressure fixing bolt nut I is installed at the bottom end of the inner bracket, and the inner bracket is prevented from slipping through the pressure action between the pressure fixing bolt nut I and the carriage plate.

[0012] The outer bracket is a rectangular bracket structure, which increases the stability of the overall structure.

[0013] The top of the outer bracket adopts a dislocation structure design, so that the whole outer bracket can effectively overlap on the upper surface of the carriage plate and is firmly connected to the inner bracket through double-headed bolts.

[0024] For better explaining the present utility model for easy understanding, the technical solutions and effects of the present utility model will be described in detail below with reference to the attached Figures 1-3 , through specific embodiments.

[0025] As Figure 1 shown, a field installation auxiliary device for a temperature sensor includes an inner bracket 16 placed inside the carriage plate 21 for installing the temperature sensor 17, and an outer bracket 31 placed outside the carriage plate 21. The inner bracket 16 is connected to the outer bracket 31 by bolts. The inner bracket 16 is designed as a triangular structure as a whole. The triangular structure has good stability and will not produce large deformation under natural conditions or the extrusion of asphalt mixture in the carriage. In addition, during the unloading process of asphalt mixture in the dump truck, as the dump truck carriage rises, the asphalt mixture gradually slides down under the action of gravity, and the mixture at the carriage plate 21 will slide in a concave arc shape as a whole. The triangular bracket structure reduces the lateral extrusion of the asphalt mixture on the inner bracket 16 and the temperature sensor 17, avoiding damage and deformation of the inner bracket 16 and the temperature sensor 17.

[0026] A temperature sensor installation hole II 20 is reserved at the bottom end of the inner bracket 16 and a sealing rubber ring II 18 is installed to realize the bottom connection of the temperature sensor 17. A pressure fixing bolt and nut I 19 is installed at the bottom end of the inner bracket 16, and the inner bracket 16 is prevented from slipping through the pressure between the pressure fixing bolt and nut I 19 and the carriage plate 21.

[0027] At the top cross beam of the inner bracket 16, a top temperature sensor installation hole I 15 is provided corresponding to the bottom temperature sensor installation hole II 20 and a sealing rubber ring I 14 is equipped. While effectively fixing and installing the temperature sensor 17, the sealing rubber ring I 14 can enable the temperature sensor 17 to produce a certain deformation under the extrusion of the asphalt mixture without damaging the temperature sensor 17.

[0028] A sensor data line perforation 11 is reserved at the top end of the inner bracket 16. The temperature sensor data line 12 can extend or be connected to the external device interface after passing through the sensor data line perforation 11. The upper part of the inner bracket 16 is designed with a dislocation structure, so that the inner bracket 16 as a whole can be connected to the outer bracket 31 through the double-headed bolt 13 and the double-headed bolt fixing nut 35 after being lapped on the upper surface of the carriage plate 21. The purpose of setting the double-headed bolt 13 for connection between the inner bracket 16 and the outer bracket 31 is to enable the inner bracket 16 and the outer bracket 31 to be adjusted flexibly to be applicable to carriage plates 21 of different thicknesses.

[0029] In this embodiment, the main body of the outer bracket 31 of the temperature sensor adopts a rectangular bracket structure design to increase the stability of the overall structure. The top of the outer bracket 31 also adopts a dislocation structure design, so that the whole outer bracket 31 can be effectively lapped on the upper surface of the carriage plate 21 and is firmly connected to the inner bracket 16 through the double-headed bolt 13.

[0030] Long-strip-shaped sliding grooves 34 are respectively reserved in the two side frames of the outer bracket 31. Pressurized fixing bolt nuts II 33 are respectively installed in the sliding grooves 34 on both sides of the outer bracket 31 of the carriage plate 21. They can be pressurized and fixed after adjusting to a proper position by sliding up and down in the sliding grooves 34, further stably installing the entire temperature sensor auxiliary device; the main function of the sliding grooves 34 is to give enough up-and-down position adjustment space to the pressurized fixing bolt nuts II 33 to adapt to the change of the rib size of different carriage plates 21.

[0031] Reference Figure 2 、 Figure 3 The installation process of the present utility model is specifically as follows:

[0032] S1. First, according to the structural characteristics of the dump truck and the change of the temperature field of the asphalt mixture, select a suitable position for temperature measurement on the carriage plate 21, and at the same time, respectively place the inner bracket 16 and the outer bracket 31 of the on-site installation of the temperature sensor on the upper surface of the carriage plate 21;

[0033] S2. After initially connecting the inner bracket 16 and the outer bracket 31 through the top double-headed bolt 13, adjust the inner and outer brackets and the double-headed bolt 13 to a proper position according to the thickness of the carriage plate 21, and then fix and connect the inner bracket 16 and the outer bracket 31 with the double-headed bolt fixing nut 35. Ensure that the inner bracket 16 and the outer bracket 31 are tightly attached to the carriage plate 21, and at the same time, straighten the overall positions of the inner and outer brackets to prevent damage caused by uneven stress due to skew.

[0034] S3. Install the pressurized fixing bolt nut I 19 at the bottom end of the inner bracket 16 and tighten and pressurize it. Prevent the inner bracket 16 from slipping through the pressure action between the pressurized fixing bolt nut I 19 and the carriage plate 21, and further ensure the stability of the structure of the inner bracket 16.

[0035] S4. For the on-site installation of the outer bracket 31, the installation position of the pressurized fixing bolt and nut II 33 is determined after the height of the outer reinforcement rib of the car panel 21 is determined. That is, after the height of the outer reinforcement rib of the car panel 21 is determined, the pressurized fixing bolt and nut II 33 can be slid up and down along the reserved sliding groove 34 of the outer bracket 31 until the pressurized fixing bolt and nut II 33 are closely attached to the bottom of the reinforcement rib of the car panel 21. After adjusting the position and angle of the pressurized fixing bolt and nut II 33, the bolt pressurization and nut fixing operations are continued until the entire temperature sensor on-site installation auxiliary device is stably installed on the car panel 21.

[0036] S5. After the overall installation of the auxiliary device is completed, insert the temperature sensor 17 from the temperature sensor installation hole Ⅰ15 with the sealing rubber ring Ⅰ14 at the upper end, and at the same time insert the lower end of the temperature sensor 17 into the temperature sensor installation hole Ⅱ20 with the sealing rubber ring Ⅱ18 and properly adjust the upper and lower positions of the temperature sensor 17 until the temperature sensor 17 is fixed without looseness; because the sealing rubber ring is resistant to high temperature and corrosion, under the action of the sealing rubber ring, the temperature sensor 17 can maintain a tight connection with the inner bracket 16 for a long time. Finally, pass the temperature sensor data line 12 through the reserved sensor data line perforation 11 at the top of the inner bracket 16. The temperature sensor data line 12 is then extended to the outside world or connected to other equipment, thereby obtaining the temperature change of the asphalt mixture during transportation. At this point, the temperature sensor 17 and its on-site installation auxiliary device are installed;

[0037] S6. After the temperature sensor 17 and the auxiliary device are installed on the dump truck, the temperature change of the asphalt mixture during transportation can be detected in real time, and the detection is carried out throughout the entire asphalt mixture transportation process;

[0038] S7: From the moment the asphalt mixture is loaded onto the truck until the asphalt mixture is unloaded at the construction site, the temperature sensor 17 and its auxiliary devices complete a complete temperature measurement. As construction continues, the temperature sensor 17 and its auxiliary devices are re-engaged in the next round of temperature measurement of the asphalt mixture.
