Description

Technical Field

[0001] This utility model relates to the field of asphalt sample technology, and in particular to an auxiliary device for pouring asphalt raw material samples. Background Technology

[0002] Asphalt is a widely used raw material in road construction, extensively used in various road surface layers, subbases, and seal coats. The quality of asphalt directly affects the overall quality and service life of the road. The most important indicators for asphalt quality testing—density, penetration, softening point, and ductility—all require the preparation of corresponding asphalt specimens. Preparing asphalt specimens involves precisely pouring molten asphalt at high temperatures into small molds of the appropriate size; the quality of this pouring determines the success or failure of subsequent tests.

[0003] In existing technologies, since the volume of different asphalt specimens is not very large, researchers currently use enamel tanks and other tools to hold, transfer, and pour heated asphalt. However, the process of pouring asphalt into molds is difficult, has a low success rate, the asphalt cannot flow evenly into the mold, air bubbles are easily generated inside the asphalt, the flow rate of asphalt cannot be precisely controlled, and the use of enamel tanks and other tools increases the risk of burns to operators. Utility Model Content

[0004] The purpose of this utility model is to provide an auxiliary device for pouring asphalt raw material samples, which enables controllable asphalt flow rate and adjustable asphalt flow velocity during the pouring process. The entire device can be placed in an oven for heating and the anti-scalding accessories can be quickly installed and removed, making the pouring process of asphalt specimens more stable and reliable.

[0005] To achieve the above objectives, an auxiliary device for pouring asphalt raw material samples is provided, comprising a first fixing ring and a high cup funnel. A first connecting rod is fixedly connected to the middle of the first fixing ring, and a cup body is fixedly connected to the other end of the first connecting rod. A buffer wheel is provided below the first fixing ring, and a rod body is fixedly connected above the first fixing ring. A second fixing ring is fixedly connected to the upper end of the rod body.

[0006] A retaining ring is fixedly connected to the upper outer part of the tall cup funnel. Hand-held rods are fixedly connected to the upper left and right sides of the tall cup funnel. A fixing block is fixedly connected to the right side of the inside of the tall cup funnel. A first turntable is fixedly connected above the fixing block. A rotating rod is rotatably connected to the middle of the first turntable. A second turntable is slidably connected to the lower left side of the rotating rod. A lifting rod is rotatably connected to the lower part of the second turntable. A plug is fixedly connected to the lower part of the lifting rod.

[0007] According to the asphalt raw material sample casting auxiliary device, a heat insulation sleeve is inserted into the left side of the left hand handle and a heat insulation sleeve is inserted into the right side of the right hand handle, and a magnetic ring is fixedly connected to one side of the heat insulation sleeve.

[0008] According to the asphalt raw material sample pouring auxiliary device, a pressing block is fixedly connected to the right side of the rotating rod, and a heat-resistant bamboo clip is provided on the right side of the pressing block.

[0009] According to the asphalt raw material sample casting auxiliary device, a return spring is fixedly connected to the left side of the rotating rod, the other end of the return spring is fixedly connected to the fixing block, and a limit block is fixedly connected to the lower left side of the rotating rod.

[0010] According to the asphalt raw material sample casting auxiliary device, a second connecting rod is fixedly connected inside the high cup funnel, and a limit ring is fixedly connected to the other end of the second connecting rod.

[0011] According to the asphalt raw material sample casting auxiliary device, the lifting rod passes through the inside of the limiting ring, and the lifting rod is slidably connected to the limiting ring.

[0012] According to the asphalt raw material sample casting auxiliary device, the high cup funnel is inserted into the inside of the second fixed ring, and the retaining ring abuts against the second fixed ring.

[0013] According to the asphalt raw material sample casting auxiliary device, the buffer wheel includes a universal wheel, a housing is fixedly connected above the universal wheel, a buffer spring is fixedly connected inside the housing, a connecting block is fixedly connected to the upper end of the buffer spring, and the connecting block is fixedly connected to the first fixing ring.

[0014] This utility model has the following beneficial effects:

[0015] 1. Compared with existing technologies, this asphalt raw material sample casting auxiliary device features a high-cup funnel made entirely of stainless steel. When the heat insulation sleeves on both sides are inserted into the hand handle, the magnetic ring adheres to the outer surface of the high-cup funnel, enabling rapid assembly of the hand anti-scalding device. Additionally, an anti-scalding bamboo clip is located on the right side of the pressing block. After the entire device is heated, the anti-scalding bamboo clip is used to hold the pressing block, allowing the operator to press it, thus achieving rapid assembly of the finger anti-scalding device. Through the combination of these two features, the user can assemble the anti-scalding device relatively quickly.

[0016] 2. Compared with the existing technology, the asphalt raw material sample pouring auxiliary device is made entirely of metal, which allows the entire device to be heated. As the pressing block is pressed down, the height of the plug rises higher and higher, that is, the material discharge speed increases, thereby controlling the material descent speed. After the pressing block is stopped, the return spring causes the plug to re-fit against the inside of the high cup funnel, at which point the high cup funnel stops discharging, thus controlling the flow rate of the asphalt raw material.

[0017] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0026] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0027] Reference Figure 1-4 The present invention provides an auxiliary device for pouring asphalt raw material samples, which includes a first fixing ring 1 and a high cup funnel 7. A first connecting rod 2 is fixedly connected to the middle of the first fixing ring 1, and a cup body 3 is fixedly connected to the other end of the first connecting rod 2. A buffer wheel 4 is provided below the first fixing ring 1. The buffer wheel 4 includes a universal wheel 41. A chamber body 42 is fixedly connected above the universal wheel 41. A buffer spring 43 is fixedly connected inside the chamber body 42. A connecting block 44 is fixedly connected to the upper end of the buffer spring 43. The connecting block 44 is fixedly connected to the first fixing ring 1.

[0028] The above structure includes a connecting block 44, with a buffer spring 43 fixedly connected to the lower part of the connecting block 44. The other end of the buffer spring 43 is fixedly connected to the housing 42, and a caster wheel 41 is fixedly connected to the lower part of the housing 42. This allows the entire device to move smoothly. When the caster wheel 41 encounters a small obstacle, the deformation of the buffer spring 43 provides a buffer protection for the first fixed ring 1 and the device above the first fixed ring 1, preventing the entire device from vibrating excessively and thus preventing the entire device from tipping over.

[0029] By incorporating a cup body 3, when the user repositions the high cup funnel 7 above the second fixing ring 6 after the molding process is completed, the residual asphalt below the high cup funnel 7 can be collected by the cup body 3, thus preventing pollution of the working environment.

[0030] A rod 5 is fixedly connected to the top of the first fixing ring 1. A second fixing ring 6 is fixedly connected to the upper end of the rod 5. A high cup funnel 7 is inserted into the inside of the second fixing ring 6. A retaining ring 8 abuts against the second fixing ring 6. A retaining ring 8 is fixedly connected to the upper outside of the high cup funnel 7. A heat insulation sleeve 10 is inserted into the left side of the left hand holding rod 9 and a heat insulation sleeve 10 is inserted into the right side of the right hand holding rod 9. A magnetic ring 11 is fixedly connected to one side of the heat insulation sleeve 10. Hand holding rods 9 are fixedly connected to the upper left and right sides of the high cup funnel 7. A fixing block 12 is fixedly connected to the right side of the inside of the high cup funnel 7. A first turntable 13 is fixedly connected above the fixing block 12. A rotating rod 14 is rotatably connected to the middle of the first turntable 13. A pressing block 15 is fixedly connected to the right side of the rotating rod 14. An anti-scalding bamboo clip 16 is provided on the right side of the pressing block 15.

[0031] The above structure, by setting a high cup funnel 7, which is made entirely of stainless steel, allows for the quick assembly of the hand anti-scalding device when the left and right heat insulation sleeves 10 are inserted into the hand handle 9. A magnetic ring 11 is fixedly connected to one side of the heat insulation sleeve 10, so that the magnetic ring 11 is attracted to the outer surface of the high cup funnel 7.

[0032] A heat-resistant bamboo clip 16 is provided on the right side of the pressing block 15. After the entire device is heated, the entire device is taken out using a clamping fixture. The heat-resistant bamboo clip 16 is used to clamp the pressing block 15, allowing the operator to press the pressing block 15 using the heat-resistant bamboo clip 16, thus realizing the rapid assembly of the finger heat-resistant device.

[0033] By pressing the pressing block 15, the rotating rod 14 rotates. A return spring 17 is fixedly connected to the left side of the rotating rod 14, and the other end of the return spring 17 is fixedly connected to the fixing block 12. At this time, the return spring 17 is stretched. A second turntable 19 is slidably connected to the left side of the rotating rod 14, and a lifting rod 20 is rotatably connected to the lower part of the second turntable 19. This causes the rotating rod 14 to drive the second turntable 19 to slide to the left side of the rotating rod 14. The upper end of the lifting rod 20 rotates inside the second turntable 19. As the rotating rod 14 rotates and the second turntable 19 slides, the lifting rod 20 moves inside the high cup funnel 7. The lifting rod 20 is fixedly connected to the lower end of the plug 21, so that the lifting rod 20 drives the plug 21 to rise synchronously. The rise of the plug 21 connects the lower part of the high cup funnel 7 with the outside, so that the asphalt contained in the high cup funnel 7 can be discharged. As the pressing block 15 presses down more and more, the height of the plug 21 rises higher and higher, that is, the material discharge speed increases, so as to control the material descent speed. After the pressing block 15 is stopped, the return spring 17 causes the plug 21 to re-fit against the inside of the high cup funnel 7, and the high cup funnel 7 stops discharging.

[0034] By enabling operators to control the flow rate of asphalt raw materials, the success rate of mold pouring is increased. By having operators hold the device with both hands simultaneously, the difficulty of the filling process is reduced.

[0035] A return spring 17 is fixedly connected to the left side of the rotating rod 14. The other end of the return spring 17 is fixedly connected to the fixed block 12. A limit block 18 is fixedly connected to the lower left side of the rotating rod 14. A second turntable 19 is slidably connected to the lower left side of the rotating rod 14. A lifting rod 20 is rotatably connected to the lower part of the second turntable 19. A plug 21 is fixedly connected to the lower part of the lifting rod 20. A second connecting rod 22 is fixedly connected to the inside of the high cup funnel 7. A limit ring 23 is fixedly connected to the other end of the second connecting rod 22. The lifting rod 20 passes through the inside of the limit ring 23. The lifting rod 20 and the limit ring 23 are slidably connected.

[0036] The above structure includes a rotating rod 14, with a second turntable 19 slidably connected to the lower left side of the rotating rod 14. A sliding groove is provided on the lower right side of the rotating rod 14, and a slider is fixed above the second turntable 19. The two correspond to each other, allowing the second turntable 19 to slide below the rotating rod 14. During the movement, the second turntable 19 will not detach from the rotating rod 14.

[0037] By setting a limit ring 23, and with the lifting rod 20 passing through the inside of the limit ring 23, the lifting rod 20 is slidably connected to the limit ring 23, so that the lifting rod 20 can stably move up or down.

[0038] Working principle: When using this asphalt raw material sample pouring auxiliary device, first remove the heat insulation sleeve 10 and the anti-scalding bamboo clip 16. Move the entire device containing asphalt into the oven for heating. After heating, use the clamping hooks to remove the entire device. Then, put the heat insulation sleeve 10 into the inside of the left and right hand handles 9 and clamp the anti-scalding bamboo clip 16 into the right side of the pressing block 15. At this time, the user holds the heat insulation sleeve 10 with both hands to remove the entire device. Align the bottom of the high cup funnel 7 with the corresponding mold and press the anti-scalding bamboo clip 16. At this time, the asphalt can flow out from the inside of the high cup funnel 7, thus completing the asphalt raw material pouring operation.

[0039] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
