Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary devices for asphalt paving, in particular to an asphalt temperature testing device for municipal road asphalt paving. Background Art

[0002] Asphalt paving is a critical step in municipal road construction and maintenance. Asphalt temperature directly impacts paving quality, pavement life, and driving safety. Existing technologies often rely on manual testing, which suffers from low efficiency, inaccuracy, and labor intensity. Operators must drill holes in the newly laid asphalt layer one by one, inserting temperature detectors into the holes to measure the internal temperature of the asphalt layer. This is used to assess whether the asphalt mixture is constructed within the appropriate temperature range to ensure the adhesion and durability of the asphalt pavement. If abnormal temperatures are detected within the asphalt layer, construction procedures, such as paving speed and rolling times, can be adjusted promptly. Asphalt pavements need to adapt to varying climatic conditions, and temperature testing helps ensure that asphalt pavements maintain their performance in all weather conditions. However, the manual drilling and inserting of test instruments significantly reduces testing efficiency and accuracy. Furthermore, testers must constantly bend over to drill holes through puncturing objects, which increases the operator's labor intensity. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the utility model provides an asphalt temperature detection device for municipal road asphalt paving, which solves the problem of low efficiency in temperature detection of newly paved asphalt in the existing technology.

[0004] In order to achieve the above-mentioned purpose, the utility model provides an asphalt temperature testing device for municipal road asphalt paving, comprising a straight-line connecting rod and a holding rod for an external operator to hold, the holding rod and the connecting rod are arranged opposite to each other, and a plurality of linkage rods are provided at the bottom of the connecting rod along its length direction, each of the linkage rods is provided with a sliding part for moving the linkage rod on the surface of the external asphalt layer, a puncture shaft for piercing the external asphalt layer is provided at the front end of the connecting rod corresponding to each linkage rod position, and a detection part for detecting the internal temperature of the external asphalt layer is provided on each puncture shaft, and a flattening shaft is provided at the rear end of the connecting rod corresponding to each linkage rod position, and each flattening shaft is provided with a flattening part for flattening the surface of the external asphalt layer.

[0005] The benefits of adopting the above technical solution are: the operator holds the holding rod, uses the sliding part on the linkage rod to adjust the position of the connecting rod, and then pushes the holding rod to make the linkage rod swing to ensure that the puncture shaft swings synchronously until it is perpendicular to the asphalt surface. When the holding rod swings, it will drive the connecting rod to rotate axially, so that the puncture shaft penetrates the asphalt layer, and the detection part immediately starts to detect the internal temperature of the asphalt. After the detection is completed, the operator swings the holding rod to make the connecting rod rotate in the opposite direction to make the puncture shaft penetrate the asphalt layer, and then pushes the holding rod to make the holding rod drive the connecting rod to move on the asphalt layer. When the connecting rod moves relative to the asphalt layer, the flattening part will flatten the punctured asphalt layer to make it flat, that is, accumulated asphalt will appear at the opening of the punctured asphalt layer. Because the asphalt has not yet hardened, the flattening part will push the asphalt back into the puncture hole or flatten the opening of the puncture hole, thereby sealing the puncture hole. The above-mentioned technical setting enables the operator to drill holes in the asphalt layer without bending over, that is, the operator only needs to swing the gripping rod to achieve the contact and puncture of the puncture shaft with the asphalt layer. At the same time, after the puncture shaft punctures the asphalt layer, the detection component will detect the internal temperature of the asphalt layer, thereby improving the detection efficiency and detection accuracy. At the same time, several puncture shafts are opened on the connecting rod, and the operator does not need to repeatedly bend over to drill holes on the surface of the asphalt layer. That is, multiple holes can be opened at the same time through several puncture shafts, thereby improving the detection range and detection efficiency, so that the asphalt paving process can be adjusted according to the internal temperature of the asphalt layer, thereby ensuring construction. Quality; In the above technology, several detection parts can be connected to the control chip for communication, and the display screen assembly and the control chip can be installed on the gripping rod according to the actual operation requirements and detection requirements, so that the control chip can transmit the detected temperature value to the display screen assembly in real time, thereby improving the detection efficiency and detection accuracy, and at the same time facilitating the operator to detect the asphalt layer. The control chip in the above technology is an existing technology, which can be a component such as a single-chip microcomputer or an intelligent mainboard, so its structure and function will not be described in detail. The display screen assembly in the above technology is an existing technology, which has a display function, so its structure and function will not be described in detail.

[0006] The present invention is further provided with: the detection component comprises an asphalt thermometer embedded in the puncture shaft, and the detection end of the asphalt thermometer is coaxially arranged with the puncture shaft.

[0007] The benefits of adopting the above technical solution are: after the puncture shaft penetrates the asphalt layer, the asphalt thermometer is simultaneously placed in the hole of the asphalt layer to detect the temperature inside the asphalt layer; the asphalt thermometer in the above technology is a small handheld device specially used to measure the temperature of asphalt and its mixture, and is widely used in road construction, asphalt production and research laboratories. Because it is an existing technology, its function and structure as well as the communication connection method with the above control chip will not be described in detail. It can realize data transmission through wire connection or setting up an adapter circuit board, and can also be equipped with an asphalt-specific temperature measuring probe according to actual application requirements and detection requirements. In the existing technology, there are multiple options for the length of the asphalt-specific temperature measuring probe, such as 0.3 meters, 0.5 meters, 1 meter, etc. Its temperature range can cover from 0 to 100 degrees or even higher temperatures, and its resolution can reach 0.1 degrees.

[0008] The utility model is further provided with: the end face of the starting end of the puncture shaft and the outer peripheral wall of the starting end of the puncture shaft are connected with a smooth curved surface and form an inclined surface; the radial cross-section of the starting end of the puncture shaft is set as an acute-angled triangle; a notch is opened on the inclined surface; the detection end of the asphalt thermometer is partially extended out of the notch.

[0009] The benefits of adopting the above technical solution are: in the above technology, the radial cross-section of the starting end of the puncture shaft is set as an acute-angled triangle to improve the smoothness of the puncture shaft insertion and the puncture efficiency. At the same time, the inclined surface is set to cut the surface of the asphalt layer, thereby improving the puncture efficiency, and the notch is set on the inclined surface, so that when the puncture shaft penetrates the interior of the asphalt layer, the detection end of the asphalt thermometer can synchronously detect the temperature, thereby improving the detection efficiency and detection accuracy.

[0010] The utility model is further provided with: the flattening part includes a flattening block with a triangular radial cross-section, the top wall of the flattening block is connected to the flattening shaft, the bottom wall of the flattening block is a flat surface for contacting the surface of the external asphalt layer, and the flat surface is connected to the side wall of the flattening block in a smooth arc surface and has rounded corners.

[0011] The benefits of adopting the above technical solution are: after the internal temperature detection of the asphalt layer is completed and the puncture shaft is pulled out from the opened hole, the operator can swing the holding rod to make the connecting rod rotate in the opposite direction, so that the pressing surface of the flattening block contacts the surface of the asphalt layer, and then when the holding rod is pushed to make the connecting rod move on the surface of the asphalt layer through the sliding part, the pressing surface can flatten the surface of the asphalt layer and push the asphalt at the opening of the hole in the asphalt layer into the hole, or flatten the opening of the hole in the asphalt layer, so as to close the opening of the hole in the asphalt layer, so as to improve the surface integrity of the asphalt layer and reduce the physical exertion of the operator. At the same time, the rounded corners are set to improve the smoothness of the pressing surface when it contacts the surface of the asphalt layer, and improve the smoothness of pushing the asphalt at the opening of the hole in the asphalt layer into the hole.

[0012] The utility model is further configured as follows: the puncture shaft and the flattening shaft are both arranged to be inclined relative to the connecting rod, and the puncture shaft and the flattening shaft are arranged in opposite inclination directions, and the puncture shaft and the holding rod are arranged in the same inclination direction.

[0013] The benefits of adopting the above technical solution are: in the above technology, the puncture shaft and the flattening shaft are both arranged to be inclined relative to the connecting rod, and the puncture shaft and the flattening shaft are arranged in opposite directions of inclination. Through the arrangement of the above technology, the operator can swing the holding rod forward to make the puncture shaft contact with the surface of the external asphalt layer, and swing the holding rod backward to make the flattening block contact with the surface of the external asphalt layer, thereby improving the detection efficiency and saving the operator's physical energy.

[0014] The utility model is further configured as follows: the sliding member comprises a universal wheel movably arranged at the bottom of the linkage rod, and the universal wheel body is made of polyurethane material.

[0015] The benefits of adopting the above technical solution are: the setting of the universal wheel in the above technology enables the operator to move the connecting rod on the surface of the external asphalt layer by pushing the gripping rod, thereby facilitating the operator's operation. At the same time, the universal wheel body is made of polyurethane material, that is, the universal wheel body adopts oil-resistant, smash-proof, and puncture-proof polyurethane material, which has the advantages of wear resistance, high temperature resistance, acid and alkali resistance, insulation, and lightness, thereby avoiding the asphalt layer from adhering to or corroding the universal wheel body, thereby improving the activity efficiency and service life of the universal wheel.
