Description

Technical Field

[0001] The present invention relates to the technical field of asphalt construction temperature measuring equipment, in particular to a temperature measuring equipment for a mixture transport vehicle. Background Art

[0002] In modern road construction, the temperature of construction materials, such as asphalt mixture, plays a crucial role in determining the quality of pavement. To ensure the mixture remains within the appropriate temperature range during paving, achieving optimal compaction and smoothness, temperature measurement equipment on mixture transport vehicles has become an essential component of the transportation process. By accurately measuring the temperature of the mixture during transportation, this equipment provides construction personnel with real-time data support, enabling them to adjust construction processes promptly and avoid quality issues such as cracks and looseness in the pavement caused by improper temperatures, thereby ensuring the overall performance and service life of the road project. Currently, the temperature measurement equipment widely used on mixture transport vehicles is mostly a probe-type structure, consisting of a probe body and a control head. The probe is inserted into the mixture, and the temperature sensor built into the control head obtains real-time temperature data of the mixture. Due to its compact structure and intuitive measurement, this equipment has been widely used in various road construction projects. However, long-term use has revealed that the probes often encounter a series of practical problems after frequent contact with hot and viscous asphalt mixtures.

[0003] However, in practical applications, traditional probe-based temperature measurement equipment suffers from the stickiness of asphalt mixtures. During the insertion and removal of the probe, the mixture easily adheres to the probe surface, affecting the accuracy of subsequent temperature measurements and increasing the difficulty and cost of equipment cleaning and maintenance. Furthermore, asphalt anti-sticking agents, used to prevent the mixture from sticking, are prone to stratification during storage and use due to their prolonged relative static state. This reduces the anti-sticking effect and makes it difficult to meet the requirements for efficient and accurate temperature measurement.

[0004] Therefore, it is necessary to provide a temperature measuring device for a mixture transport vehicle to solve the above technical problems. Summary of the Invention

[0014] Compared with related technologies, the temperature measuring device for a mixture transport vehicle provided by the present invention has the following beneficial effects: The present invention provides a temperature measuring device for a mixture transport vehicle. The control button of the driving motor of the present invention can be directly installed in the cab of the transport vehicle or installed on one side of the hopper, and is mounted in conjunction with a U-shaped positioning block. Therefore, when it is necessary to measure the temperature of the asphalt material, the operator only needs to control it through buttons in the cab or standing on the ground, and there is no need to stand on the hopper to vertically plug in the temperature measurement, which makes the operation more convenient. At the same time, when the probe body enters the hopper for temperature measurement, the asphalt anti-sticking agent adsorbed on the adsorption sponge will be evenly coated on the outer wall of the probe body. In this way, when the probe body is working, the asphalt material can be effectively prevented from sticking to its surface wall, the temperature measurement accuracy of the probe thermometer is guaranteed, and the service life of the probe thermometer is extended.

[0015] The present invention provides a temperature measuring device for a mixture transport vehicle. When the screw rotates, the driving bevel gear is synchronously driven to rotate together. After the driving bevel gear rotates, the bevel gear shaft is driven to rotate on the shaft frame. The bevel gear shaft drives the support arm to make a circular motion. The ring at one end of the support arm drives the support rod and the sleeve to move synchronously. At this time, the sleeve slides back and forth along the guide rod, and the support rod reciprocates and extends and contracts in the vertical direction relative to the ring. At the same time, the sleeve squeezes the guide rod and swings back and forth in the circumferential direction, that is, the storage shell swings back and forth between the two arc-shaped plates, and the asphalt anti-sticking agent stored in the fan-shaped cavity follows the swing, which effectively avoids the stratification of the asphalt anti-sticking agent after standing still, and the shaking can efficiently replenish the asphalt anti-sticking agent to the adsorption sponge.

[0016] The present invention provides a temperature measuring device for a mixture transport vehicle. When the sleeve slides a certain distance on the guide rod, it will contact the displacement plate and push the displacement plate to slide on the guide rod. The displacement plate drives the resistance rod to move toward the connecting plate and contact it, and the reset spring is compressed to generate a rebound force. After the contact, an extrusion force is applied to the side wall of the connecting plate, so that the connecting plate moves on the positioning rod, that is, the scraper installed at the bottom of the connecting plate moves relative to the probe body and axially scrapes it. When the sleeve is separated from the displacement plate, the rebound force generated by the compression of the reset spring and the positioning spring respectively drives the displacement plate and the connecting plate to reset, so that the scraper moves back and forth axially relative to the surface of the probe body, and scrapes it back and forth. The axial shear force further improves the cleaning effect of the surface of the probe body. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0019] In addition, the following terms are defined based on the functions of the present invention and may vary depending on the intentions or practices of the user or operator. Therefore, these terms are defined based on the entire content of this specification.

[0020] See also Figures 1-6 The temperature measuring device for a mixture transport vehicle of the present invention comprises a hopper 1, which is a conventional transport vehicle hopper on the market, and a probe hole 11 for detecting temperature is opened on the side of the hopper 1. The diameter of the probe hole 11 is not greater than 2 cm, ensuring that the temperature can be measured while preventing the asphalt material from leaking out. A U-shaped positioning block 2 is installed at the top of the hopper 1. The internal gap of the U-shaped positioning block 2 matches the gap of the hopper 1. The U-shaped positioning block 2 and the hopper 1 are locked and fixed by a positioning bolt 21. The end of the positioning bolt 21 is embedded with a silicone pad, which increases the friction with the outer wall of the hopper 1. The outer wall of the U-shaped positioning block 2 is fixedly mounted with a support frame 3, and a probe-type thermometer 4 is mounted on the upper outer side of the support frame 3. The probe-type thermometer 4 is a prior art, and its specific working principle is not repeated in this embodiment. The probe-type thermometer 4 is connected by a probe body 41 and a control head 42 through a wire. The control head 42 is mounted on one side of the support frame 3. The control head 42 can display the detected temperature in real time. A positioning block 5 is fixedly mounted on the outer side of the probe body 41; The support frame 3 is symmetrically mounted with guide rods 31 at the lower position. A screw rod 32 is rotatably mounted at the bottom of the support frame 3 and between the two guide rods 31. A sleeve 33 is mounted on the screw rod 32. Both ends of the sleeve 33 are plugged into the outer walls of the two guide rods 31. The two guide rods 31 lock the circumferential rotation position of the sleeve 33. The top of the positioning block 5 is connected to the sleeve 33 through a connecting rod 6. The probe body 41 is kept coaxial with the probe hole 11 by the positioning block 5. In this state, if the probe body 41 moves horizontally, it can be inserted into the hopper 1 along the probe hole 11. A driven gear 34 is installed on the outer wall of the screw rod 32 and located between the sleeve 33 and the support frame 3. A driving motor 35 is installed on the outer side of the support frame 3 through a fixed frame. The output end of the driving motor 35 is concentrically connected to the driving gear 36, and the driving gear 36 is meshed with the driven gear 34. During operation, the driving motor 35 is started to work, and the driving motor 35 drives the driving gear 36 to rotate. The rotating driving gear 36 then drives the driven gear 34 to rotate. After the driven gear 34 rotates, it drives the screw rod 32 to rotate together, thereby driving the sleeve 33 to slide on the outer walls of the two guide rods 31, and then drives the probe body 41 through the probe hole 11 and into the hopper 1 through the connecting rod 6 and the positioning block 5 to detect the temperature of the asphalt material filled in the hopper 1; The control button of the drive motor 35 can be directly installed in the cab of the transport vehicle or installed on the side of the hopper 1, and matched with the mounting type installation of the U-shaped positioning block 2. Therefore, when the temperature of the asphalt material needs to be measured, the operator only needs to control it by pressing the button in the cab or standing on the ground, without having to stand on the hopper 1 to vertically insert the temperature measurement, which is more convenient to operate; A brushing assembly 7 is installed below the support frame 3, and asphalt anti-sticking agent is applied to the outer wall of the probe body 41 through the brushing assembly 7.

[0021] In another embodiment, see Figures 1-6The painting assembly 7 includes positioning plates 71 symmetrically fixed to the two side walls of the support frame 3, and arc-shaped plates 72 are fixedly installed at the ends of the two positioning plates 71. A storage shell 73 is rotatably connected between the two arc-shaped plates 72, and the storage shell 73 is a metal component; A through hole 74 is formed in the axial center of the storage shell 73, and the probe body 41 is inserted into the through hole 74. A fan-shaped cavity 75 is formed in the storage shell 73 at equal angles along the circumferential direction. A feeding port 77 is provided on one side of the fan-shaped cavity 75. The feeding port 77 is equipped with a sealing plug. Asphalt anti-sticking agent can be added to the fan-shaped cavity 75 for storage through the feeding port 77. An adsorption sponge 76 is embedded in each fan-shaped cavity 75 near the through hole 74. Part of the asphalt anti-sticking agent stored in the fan-shaped cavity 75 is adsorbed in the adsorption sponge 76. The inner wall of the adsorption sponge 76 is tightly attached to the outer wall of the probe body 41. Therefore, when the probe body 41 enters the hopper 1 for temperature measurement, the asphalt anti-sticking agent adsorbed on the adsorption sponge 76 will be evenly coated on the outer wall of the probe body 41. In this way, when the probe body 41 is working, it can effectively prevent the asphalt material from sticking to its surface wall, so that the temperature measurement accuracy of the probe thermometer 4 is guaranteed and the service life of the probe thermometer 4 is extended.

[0022] In another embodiment, see Figure 2-Figure 6 The outer wall of the storage shell 73 is symmetrically mounted with flat plates 731, a guide rod 732 is mounted between the two flat plates 731, and a sleeve 733 is sleeved on the outer wall of the guide rod 732. The sleeve 733 can move axially and rotate circumferentially along the guide rod 732; A support rod 734 is welded to the outer wall of the sleeve 733 in the vertical direction. A collar 735 is sleeved on the outer wall of the support rod 734. A ball is embedded in the inner wall of the collar 735, and the ball abuts against the outer wall of the support rod 734. That is, the collar 735 can rotate circumferentially and move vertically along the support rod 734. The outer wall of the collar 735 is welded with a support arm 736 in the horizontal direction. The support arm 736 and the collar 735 can be understood as an integral part. A bevel gear shaft 737 is fixedly mounted on the top of the end of the support arm 736. A shaft bracket 730 is mounted on the bevel gear shaft 737, and the shaft bracket 730 is fixed on the support frame 3. The axis of the bevel gear shaft 737 remains coincident with the center of the guide rod 732. The top of the bevel gear shaft 737 is meshed with a driving bevel gear 738, and the driving bevel gear 738 is concentrically fixed to the outer wall of the screw rod 32. When the screw rod 32 rotates, the driving bevel gear 738 is synchronously driven to rotate together. After the driving bevel gear 738 rotates, it drives the bevel gear shaft 737 to rotate on the shaft frame 730. The bevel gear shaft 737 drives the support arm 736 to make a circular motion. The collar 735 at one end of the support arm 736 drives the support rod 734 and the sleeve 733 to move synchronously. At this time, the sleeve 733 slides back and forth along the guide rod 732, and the support rod 734 reciprocates and telescopes in the vertical direction relative to the collar 735. At the same time, the sleeve 733 squeezes the guide rod 732 along Figure 3 The N-direction reciprocating swing shown, that is, the storage shell 73 swings back and forth between the two arc-shaped plates 72, and the asphalt anti-sticking agent stored in the fan-shaped cavity 75 follows the swing, which effectively avoids the stratification of the asphalt anti-sticking agent after standing still, and the swing can efficiently replenish the asphalt anti-sticking agent to the adsorption sponge 76.

[0023] In another embodiment, see Figure 2-Figure 6 The outer wall of the probe body 41 is sleeved with a scraper 8 between the hopper 1 and the storage shell 73. The outer ring of the scraper 8 is fixedly mounted with a connecting plate 81. The top of the connecting plate 81 is provided with a positioning hole 82. A positioning rod 83 is inserted into each of the two positioning holes 82, and a baffle 84 is fixedly installed at the end of the positioning rod 83. Positioning springs 85 are symmetrically installed on the outer wall of one of the positioning rods 83 and on both sides of the connecting plate 81. The two positioning springs 85 are made of the same material and model. Under the action of the two positioning springs 85, the connecting plate 81 is centered and maintained in the center position of the positioning rod 83. When the probe body 41 moves horizontally, the scraper 8 will physically scrape the surface of the probe body 41, further improving the cleanliness of the probe body 41, thereby further ensuring the measurement accuracy and service life of the probe-type thermometer 4.

[0024] In another embodiment, see Figure 2-Figure 6 The flat plate 731 on the side facing the connecting plate 81 has symmetrically opened insertion holes 89, and the outer wall of the guide rod 732 has symmetrically opened guide grooves 86. A guide block 87 is installed in the guide groove 86. A displacement plate 88 is fixedly installed on the outer wall of the guide block 87. The guide block 87 can move along the guide groove 86, and the displacement plate 88 moves with the guide block 87. The maximum movable distance of the displacement plate 88 is equal to the designed length of the guide groove 86. The side wall of the displacement plate 88 is symmetrically installed with a resistance rod 881, and the resistance rod 881 is inserted into the outer wall of the guide rod 732 in the insertion hole 89 and a return spring 882 is installed between the flat plate 731 and the displacement plate 88. In the initial state, the elastic force of the return spring 882 pushes the guide block 87 to move to the end of the guide groove 86 away from the connecting plate 81. When the sleeve 733 slides a certain distance on the guide rod 732, it will contact the displacement plate 88 and push the displacement plate 88 to slide on the guide rod 732. The displacement plate 88 drives the resistance rod 881 to move toward the connecting plate 81 and contact it, and the return spring 882 is compressed to generate a rebound force. After contact, an extrusion force is applied to the side wall of the connecting plate 81, causing the connecting plate 81 to move on the positioning rod 83, that is, the scraper 8 installed at the bottom of the connecting plate 81 moves relative to the probe body 41 to scrape it axially; If the sleeve 733 is separated from the displacement plate 88, the rebound force generated by the compression of the reset spring 882 and the positioning spring 85 drives the displacement plate 88 and the connecting plate 81 to reset respectively, so that the scraper 8 moves back and forth axially relative to the surface of the probe body 41, performing a reciprocating scraping operation on it, and the axial shear force further improves the cleaning effect of the surface of the probe body 41.

[0025] At the same time, if Figure 4 As shown, the two side walls of the connecting plate 81 are symmetrically welded with extension plates 811, and the setting path of the extension plate 811 matches the deflection path of the interference rod 881. The extension plate 811 increases the coverage area on both sides of the connecting plate 81, and the interference rod 881 can slide on the outer side walls of the connecting plate 81 and the extension plate 811 to prevent the interference rod 881 from detaching from the side walls of the connecting plate 81.

[0026] Among them, a semicircular groove is opened at the end position of the resistance rod 881, and a steel ball is embedded in the semicircular groove, so that after the resistance rod 881 contacts the connecting plate 81 and the extension plate 811, the steel ball moves on the surface of the connecting plate 81 and the extension plate 811, reducing mutual wear through rolling friction.

[0027] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention description and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
