Abstract
Description
Technical Field
[0001] The present invention relates to the field of road construction machinery, and in particular to an asphalt concrete transfer vehicle with a foldable side operation position. Background Art
[0002] An asphalt concrete transfer vehicle is a supporting equipment for the construction operation of the asphalt concrete surface layer of a high-grade highway. Its function is to quickly receive and store the mixture from the transport vehicle and transfer the mixture to the paver.
[0003] Usually, the transport vehicle directly unloads the mixture into the paver for the road surface construction operation. When each transport vehicle finishes unloading and the next transport vehicle is replaced, the paver needs to stop and wait, and the stable state of continuous construction is destroyed. Defects such as indentations or raised platforms that affect the flatness of the road surface are likely to appear at the road surface where the machine stops. At the same time, the shutdown also causes a decrease in the road surface construction efficiency.
[0004] Adding an asphalt concrete transfer vehicle device between the transport vehicle and the paver avoids the direct contact between the paver and the transport vehicle, ensures the uninterrupted and continuous construction operation of the paver, and thus ensures the paving of a high-quality road surface. At the same time, the transfer vehicle has a secondary mixing function. During the transmission process of the mixture, it can perform secondary mixing on the mixture, maximizing the elimination of temperature segregation and aggregate segregation generated during the production, transportation, and unloading of the asphalt mixture, making the temperature and gradation of the asphalt mixture uniform. It provides an effective solution for improving the construction quality and efficiency of highways, extending the service life of highways, saving maintenance costs, reducing environmental pollution and resource waste.
[0005] During the process of the transport vehicle unloading materials to the transfer vehicle, usually a construction operator is required to be responsible for guiding the docking of the transport vehicle and the transfer vehicle, controlling the unloading speed of the transport vehicle, and the speed of transferring the mixture in the receiving hopper of the transfer vehicle to the storage bin of the transfer vehicle. Therefore, it is very necessary to set a control panel at the positions on both the left and right sides of the transfer vehicle, close to the rear of the receiving hopper, which can control functions such as the lifting of the receiving hopper, the opening and closing of the material gate, and the control of the material transfer speed.
[0006] However, in the construction of the existing technology, the following problems exist: 1. Poor comfort: The operator needs to move along with the movement of the transfer vehicle, and long-term operation is likely to cause fatigue; 2. Potential safety hazards: The operator walks on the uncompleted road surface for a long time, especially when approaching the edge of the road surface, there is a risk of falling; 3. Inconvenient observation: The side wall height of the receiving hopper is relatively high, which hinders the operator from directly observing the material state.
[0007] Therefore, it is necessary to develop a new type of asphalt concrete transfer vehicle specifically to overcome the above problems. Summary of the Invention

Detailed Embodiments
[0030] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0031] As shown in the attached Figure 1 、 Figure 2 figures, taking the left side of the transfer vehicle as an example, at the very front of the transfer vehicle, there is a receiving hopper 1 for receiving the mixture in the material transport vehicle. The primary material conveying device 2 conveys the mixture received by the receiving hopper 1 into the storage bin 5. In order to direct the docking of the material transport vehicle and the transfer vehicle, control the discharging speed of the material transport vehicle, and the speed of the mixture in the receiving hopper of the transfer vehicle being conveyed into the storage bin of the transfer vehicle, a control panel 3 is provided at the rear position of the receiving hopper 1, facilitating the operator to control functions such as the lifting of the receiving hopper, the opening and closing of the material gate, and the control of the conveying speed. In order to enable the operator to operate more comfortably and safely, a side operating position with a foldable function is provided opposite the control panel. During construction, the operator can sit and operate, as shown in Figure 7 the figure; the operating position is equipped with a footrest device, and the operator can conveniently stand on it at any time to observe the situation inside the receiving hopper, as shown in Figure 8 the figure.
[0032] As shown in Figure 3 、 Figure 4 the figures, the side operating position 4 is composed of a mounting seat 41, a support frame 42, a seat surface 43, and a footrest 44. The mounting seat 41 is fixed to the rear position of the receiving hopper 1 by bolts. The support frame 42 is connected to the mounting seat 41 through a rotating pin shaft 45 and a limit pin shaft 46. The seat surface 43 is composed of a seat surface and a bottom sleeve, and is connected to the support frame 42 in a sleeve form. The position of the seat surface 43 relative to the support frame 42 can be telescopically adjusted; multiple groups of positioning holes are provided on the support frame 42. After the seat surface 43 is adjusted to the appropriate position, it is fixed by a positioning pin shaft 410. A quick disassembly and assembly pull ring 47 is installed on the positioning pin shaft 410 to facilitate quick disassembly and adjustment. A limit hole is provided at the bottom of the positioning pin shaft 410, and a limit spring pin 49 can be installed to prevent the positioning pin shaft 410 from accidentally coming out. A footrest 44 is installed at the lower part of the support frame 42. The footrest 44 is quickly hooked to the mounting plate 421 with a double inverted L-shaped card slot at the bottom of the support frame 42 through the tenon head 442 at the upper part, facilitating disassembly and assembly.
[0033] The support frame 42 can rotate around the rotating pin shaft 45. When the operator is in the sitting operation state, the support frame 42 is in a horizontal state; after the construction is completed and the transfer vehicle needs to be transported, the support frame 42 can rotate to the vertical storage position. The mounting seat 41 is provided with two groups of mounting holes for the limit pin shaft 46 to limit the support frame 42 when it is in the horizontal position and the vertical position respectively. Figure 3 is a schematic diagram of the side operating position 4 in the working state, Figure 5 is a schematic diagram of the side operating position 4 in the transport folding state.
[0034] As shown inFigure 5 As shown, on the side wall of the receiving hopper 1, there is also an installation plate 421 with a double inverted L-shaped card slot. When the side operation position 4 is in the transportation and folding state, the footrest 44 is removed from the support frame 42 and hung on the installation plate 421 with a double inverted L-shaped card slot on the side wall of the receiving hopper 1. The whole process is very convenient and fast.
[0035] The present invention provides a foldable side operation position at the position of the side operation table, which includes an installation seat, a support frame, an adjustable seat surface and a quickly detachable and installable footrest. The operation position realizes the switching between the horizontal working position and the vertical storage position through a rotating pin shaft and a limiting pin shaft. The support frame is equipped with multiple groups of positioning pin holes to meet the needs of operators of different body types. The footrest adopts a quick hanging connection design of a tenon head and a double inverted L-shaped card slot, which is convenient to be fixed on the side wall of the hopper after disassembly. The present invention can make the work of the side operator of the transfer vehicle more comfortable and safe. At the same time, it enables the operator to more conveniently observe the situation of the asphalt mixture in the hopper and make relevant adjustments and operations in a timely manner. At the end of the construction, it can be easily folded and stored without affecting the transportation of the transfer vehicle. This design significantly improves the operation comfort and safety of the transfer vehicle.
