Description

Technical Field

[0001] This invention relates to the field of road construction machinery, and more particularly to an asphalt concrete transport vehicle with a foldable side operating position. Background Technology

[0002] An asphalt concrete transfer vehicle is a supporting equipment for the construction of asphalt concrete pavement on high-grade highways. Its function is to quickly receive and store the mixture from the material transport vehicle and transfer the mixture to the paver.

[0003] Typically, material trucks unload the mixture directly onto the paver for road construction. When each truck finishes unloading and the next truck arrives, the paver needs to stop and wait, disrupting the stable continuous construction process. Defects such as indentations or ridges can easily appear at the stop points, affecting road surface smoothness. The downtime also reduces road construction efficiency.

[0004] By adding asphalt concrete transfer vehicles between the material transport trucks and the paver, direct contact between the two is avoided, ensuring uninterrupted and continuous operation for the paver and guaranteeing high-quality pavement. Simultaneously, the transfer vehicles have a secondary mixing function, re-mixing the asphalt mixture during transport to minimize temperature and aggregate segregation that occurs during production, transportation, and unloading, resulting in a more uniform temperature and gradation of the asphalt mixture. This provides an effective solution for improving highway construction quality and efficiency, extending highway service life, saving maintenance costs, and reducing environmental pollution and resource waste.

[0005] During the unloading process from the material transport vehicle to the transfer vehicle, a construction operator is usually required to direct the docking of the two vehicles, control the unloading speed of the material transport vehicle, and the speed at which the mixture in the receiving hopper of the transfer vehicle is transferred to the storage bin of the transfer vehicle. Therefore, it is essential to install a control panel on both sides of the transfer vehicle, near the rear of the receiving hopper, to control functions such as raising and lowering the receiving hopper, opening and closing the material gate, and controlling the material conveying speed.

[0006] However, the following problems exist in the construction of existing technologies: 1. Poor comfort: Operators need to move with the transfer vehicle, and long-term operation can easily lead to fatigue; 2. Safety hazards: Operators walk on the unfinished road surface for a long time, especially when close to the edge of the road surface, which may cause them to fall or fall; 3. Difficulty in observation: The side wall of the receiving hopper is relatively high, which hinders the operator from directly observing the material status.

[0007] Therefore, it is necessary to develop new types of asphalt concrete transport vehicles to overcome the above problems. Summary of the Invention

[0008] Purpose of the invention: To address the shortcomings and defects of existing technologies, this invention provides an asphalt concrete transfer vehicle with foldable side operating positions. By setting up foldable side operating positions on both sides of the transfer vehicle near the rear of the receiving hopper, operators can sit while working during construction. Equipped with foot pedals, operators can stand on them to observe the situation inside the receiving hopper, providing a safer, more comfortable, and convenient working environment. After construction, the vehicle can be easily folded and stored without being affected by excessive width during transport.

[0009] Technical solution: The present invention provides an asphalt concrete transfer vehicle with a foldable side operating position, comprising:

[0010] A receiving hopper for receiving paving materials;

[0011] The primary conveying device that transports the mixed material received by the receiving hopper to the storage silo;

[0012] Control panels located on both sides of the rear of the receiving hopper are used to control the lifting and lowering of the receiving hopper, the opening and closing of the material gate, and the conveying speed.

[0013] A foldable side operating position is installed at the rear of the receiving hopper and corresponds to the control panel; the side operating position includes a mounting base, a support frame, a stool surface, and a footstool.

[0014] The support frame is hinged to the mounting base via a rotating pin and a limiting pin. The limiting pin has two sets of mounting holes for limiting the support frame to a horizontal working position and a vertical storage position.

[0015] The rotating pin is connected to the self-locking nut.

[0016] The stool surface is slidably connected to the support frame via a sleeve. The support frame is provided with multiple sets of positioning pin holes. The position of the stool surface is fixed by the positioning pin shaft. The positioning pin shaft is equipped with a quick-release pull ring and a limit spring pin.

[0017] The foot pedal is provided with a tenon at the top, and a mounting plate with double inverted L-shaped slots is installed at the bottom of the support frame. The tenon and the slots match to achieve quick connection. After the foot pedal is disassembled, it is hung on a spare mounting plate with double inverted L-shaped slots on the side wall of the receiving hopper.

[0018] The foot pedals at the bottom of the pedals have a serrated anti-slip structure.

[0019] During construction, operators adjust and fix the seat position by sitting, and switch to standing position by using foot pedals to observe the materials in the receiving hopper. After construction, the support frame is folded to a vertical position and the foot pedals are removed and attached to the side wall of the receiving hopper to achieve quick storage of the equipment.

[0020] Beneficial Effects: Compared with existing technologies, this invention has the following significant advantages: This invention features a foldable side operating position on the side workbench, including a mounting base, support frame, adjustable seat, and quick-release foot pedal. The operating position can be switched between a horizontal working position and a vertical storage position via a rotating pin and a limiting pin. The support frame is equipped with multiple sets of positioning pin holes to accommodate operators of different body types. The foot pedal adopts a quick-attach design with tenons and double inverted L-shaped slots, facilitating disassembly and fixation to the side wall of the hopper. This invention makes side-operation of the transfer vehicle more comfortable and safer, while allowing operators to more easily observe the asphalt mixture in the hopper and make timely and convenient adjustments and operations. At the end of construction, it can be easily folded and stored without affecting the transport of the transfer vehicle. This design significantly improves the operational comfort and safety of the transfer vehicle. Attached Figure Description

Detailed Implementation

[0030] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0031] As attached Figure 1 , Figure 2 As shown, taking the left side of the transfer vehicle as an example, a receiving hopper 1 is located at the very front of the transfer vehicle to receive the mixed material from the transport vehicle. The primary conveying device 2 transports the mixed material received by the receiving hopper 1 to the storage silo 5. To coordinate the docking of the transport vehicle and the transfer vehicle, control the unloading speed of the transport vehicle, and the speed at which the mixed material in the receiving hopper of the transfer vehicle is transferred to the storage silo of the transfer vehicle, a control panel 3 is located at the rear of the receiving hopper 1. This allows operators to control functions such as lifting and lowering the receiving hopper, opening and closing the material gate, and controlling the conveying speed. To make operation more comfortable and safer for operators, a foldable side operating position is located opposite the control panel, allowing operators to operate while seated during construction. Figure 7 As shown; the operating position is equipped with a foot pedal, allowing the operator to easily stand on it at any time to observe the situation inside the receiving hopper, such as... Figure 8 As shown.

[0032] like Figure 3 , Figure 4 As shown, the side operating position 4 consists of a mounting base 41, a support frame 42, a seat 43, and a foot pedal 44. The mounting base 41 is fixed to the rear of the receiving hopper 1 by bolts. The support frame 42 is connected to the mounting base 41 by a rotating pin 45 and a limiting pin 46. The seat 43 consists of a seat surface and a bottom sleeve, which is connected to the support frame 42 by the sleeve. The position of the seat 43 relative to the support frame 42 is adjustable. The support frame 42 is provided with multiple sets of positioning holes. After the seat 43 is adjusted to the appropriate position, it is fixed by a positioning pin 410. The positioning pin 410 is equipped with a quick-release pull ring 47 for easy and quick disassembly and adjustment. The bottom of the positioning pin 410 is provided with a limiting hole for installing a limiting spring pin 49 to prevent the positioning pin 410 from accidentally coming out. A foot pedal 44 is installed at the lower part of the support frame 42. The foot pedal 44 can be quickly attached to the mounting plate 421 with double inverted L-shaped slots at the bottom of the support frame 42 via the tenon 442 at the top, which is convenient for disassembly and assembly.

[0033] The support frame 42 can rotate around the rotating pin 45. When the operator is in a seated position, the support frame 42 is in a horizontal position. After construction is completed, when the transport vehicle needs to transport the equipment, the support frame 42 can be rotated to a vertical storage position. The mounting base 41 is provided with two sets of mounting holes for the limiting pins 46, which limit the support frame 42 when it is in the horizontal and vertical positions, respectively. Figure 3 This is a schematic diagram showing the side operation position 4 in the working state. Figure 5 This is a schematic diagram showing the side operation position 4 in a transport folded state.

[0034] like Figure 5 As shown, a mounting plate 421 with double inverted L-shaped slots is also provided on the side wall of the receiving hopper 1. When the side operation position 4 is in the transport folding state, the foot pedal 44 is removed from the support frame 42 and hung on the mounting plate 421 with double inverted L-shaped slots on the side wall of the receiving hopper 1. The whole process is very convenient and quick.

[0035] This invention features a foldable side operating position on the side workbench, comprising a mounting base, support frame, adjustable seat, and quick-release footrest. The operating position can be switched between a horizontal working position and a vertical storage position via a rotating pin and a limiting pin. The support frame is equipped with multiple sets of positioning pin holes to accommodate operators of different body types. The footrest uses a tenon and double inverted L-shaped slot quick-attachment design, facilitating easy disassembly and fixation to the side wall of the hopper. This invention makes side-operation of the transfer vehicle more comfortable and safer, while allowing operators to more easily observe the asphalt mixture in the hopper and make timely and convenient adjustments and operations. At the end of construction, it can be easily folded and stored without affecting the transport of the transfer vehicle. This design significantly improves the operational comfort and safety of the transfer vehicle.
