Description

Technical Field

[0001] The invention belongs to the technical field of urban internal traffic and is a device for realizing the turning, branching and merging of automatic road transport vehicles. Background Art

[0002] In order to solve a series of problems such as traffic congestion, environmental pollution, increased accidents, and energy waste within the city, a new type of transportation facility - automatic road transport vehicle (invention patent number is ZL 20110045796.9) is disclosed. The automatic road transport vehicle includes a boarding acceleration section, a conveying section, and a disembarking deceleration section. The acceleration section is composed of a number of sub-sections with uniformly increasing speeds in series. Each sub-section has a station track and handrails with the same speed to achieve the transition from starting to smooth and fast transportation. The conveying section consists of a station track, a seat track, and a handrail. The three are synchronized, including a driving wheel, a conveyor belt, a handrail belt, and a roller. The structural principle is similar to that of an automatic sidewalk or a belt conveyor, achieving smooth and fast transportation. The deceleration section and the acceleration section are symmetrical in structure to achieve multi-level uniform deceleration.

[0003] Passengers hold the handrails, board the bus in turn, and stand on the starting belt. The acceleration section accelerates the passengers into the conveying section. After entering the conveying section, the passengers can sit on the seat track, stand on the standing track, or walk on the standing track. There are multiple prompts before arriving at the station, and the passengers get off the bus after the deceleration section decelerates the passengers in stages.

[0004] The implementation method is selected according to the length of the line and the street conditions: the first is the segmented serial connection type, that is, the entire road vehicle is composed of segments connected in series, and each segment consists of five major parts: acceleration section, conveying section, deceleration section, power and transmission device, and sunshade and rain awning. This method is easy to set up, but inconvenient to ride. Passengers must get off first and then get on at each station. The second is the intermediate station type, that is, the handrail on one side of the conveying section station road is disconnected and the acceleration and deceleration sections are configured in parallel, and several intermediate stations are set. In this way, passengers only get off at the destination, saving the trouble of frequent getting on and off. However, at a large turning angle (greater than 30°), it is impossible to use a simple head-to-tail plug-in method to turn (turn) or branch or merge, so it cannot be realized. Summary of the invention

[0005] In order to solve the problem that the conveying section of the automatic road conveying vehicle cannot achieve a large angle of steering (turning), branching or merging, the present invention discloses a device for the conveying section of the automatic road conveying vehicle to steering, branching, or merging at any angle.

[0006] The technical solution adopted by the present invention to solve its technical problems is: a steering, branching and merging device for an automatic road transport vehicle is composed of a deceleration mechanism, a steering mechanism and an acceleration mechanism. The deceleration mechanism is connected in parallel with the conveying section of the automatic road transport vehicle, the acceleration mechanism is connected in parallel with the conveying section that needs to be turned, branched or merged, the turntable of the steering mechanism is attached to the tail and head ends of the deceleration and acceleration mechanism, and is driven by the driving mechanism below to rotate at a slower speed similar to the tail and head ends of the deceleration and acceleration mechanism. The convex handrail is a circular ring coaxial with the turntable, fixed above the middle of the turntable with a thin waist cylinder, and the concave handrail is in the shape of an arc surface. The handrail belt is shaped by a guide wheel installed on the arc surface mounting plate, and the three guide wheels at the bottom press the handrail belt on the two friction wheels for friction transmission, and the tray wheel and the friction wheel are correspondingly supported under the edge of the turntable.

[0007] The initial speed of the reduction mechanism is the same as or slightly lower than the speed of the conveying section of the automatic conveyor road vehicle. It is composed of sub-segments with decreasing speeds connected in series. The driving wheel and the driven wheel of the front and rear sub-segment conveyor belts have the same diameter and are installed on the same shaft and connected to the shaft with keys and bearings respectively. The driving wheel is fixedly connected to the shaft to drive the conveyor belt to rotate, while the driven wheel is driven by the conveyor belt to slide on the shaft, thereby achieving speed change and smooth transmission.

[0008] The acceleration mechanism is symmetrical to the reduction mechanism.

[0009] The steering mechanism consists of a turntable, a concave handrail, a convex handrail and a drive mechanism. The tray is made of patterned steel plate and is attached to the tail and head ends of the deceleration and acceleration mechanism. The drive mechanism below rotates at a slower speed similar to the tail and head ends of the deceleration and acceleration mechanism. The speed is less than 25 rpm to avoid a large centrifugal force on the passengers to ensure their safety and comfort. The convex handrail is a circular ring, coaxial with the turntable, and fixed above the middle of the turntable with a small cylinder in the middle. The concave handrail is an arc surface, and the handrail belt is friction driven.

[0010] Furthermore, the concave edge handrail comprises an arc surface mounting plate, a handrail guide wheel, a friction wheel and a tray wheel. The arc surface mounting plate is fixed to the outer side of the turntable and has a symmetrical structure. The guide wheel, the friction wheel and the tray wheel mounting holes are formed on the arc surface mounting plate. The handrail is shaped by the guide wheel. The arc length of the upper handrail section is determined by the rotation angle (l=θ / 360πD, where l is the arc length, θ is the rotation angle, π is the pi, and D is the turntable diameter). The lower transmission section is composed of three guide wheels pressing on two friction wheels. The friction wheels and the tray wheels correspond to each other up and down on the edge of the turntable.

[0011] The beneficial effects of the device are as follows: the requirements for turning, branching, or merging at any angle can be met by simply changing the arc length of the concave handrail; a smooth connection between a higher-speed conveying section and a lower-speed turntable is achieved through a deceleration mechanism and an acceleration mechanism, avoiding excessive centrifugal force caused by an excessively high turntable speed, which may cause discomfort or danger to passengers, thereby replacing the current public buses and most private transportation in the city, solving a series of problems such as traffic congestion and environmental pollution, and ensuring convenient and green travel for citizens.

Specific implementation plan

[0016] The specific implementation of the device is further described below in conjunction with the accompanying drawings:

[0017] 90° deflection, branching, and merging devices such as Figure 1 , Figure 2 As shown, it is composed of a reduction mechanism 1, a steering mechanism 2 and an acceleration mechanism 3. The reduction mechanism 1 is connected in parallel with the conveying section of the automatic conveying road vehicle, and the acceleration mechanism 3 is connected in parallel with the conveying section that needs to be turned, branched or merged. The turntable 21 of the steering mechanism 2 is attached to the tail end of the reduction mechanism 1 and the head end of the acceleration mechanism 3. The driving mechanism 24 is arranged under the turntable 21. The rotation speed of the turntable 21 is relatively slow, and the circumferential speed is close to the tail end speed of the reduction mechanism 1.

[0018] The speed reduction mechanism 1 is composed of serially connected sub-segments with decreasing speeds. The driving wheel and the driven wheel of the front and rear sub-segment conveyor belts have the same diameter and are respectively installed on the same shaft with keys and bearings. The driving wheel drives the conveyor belt to rotate, while the driven wheel is driven by the conveyor belt to slide on the shaft, thereby achieving speed change and smooth transmission. The structural principle of the mechanism is the same as the automatic conveyor road vehicle disembarkation speed reduction section, with 3-4 less sub-segments, the initial speed is the same as or slightly lower than the conveying section, and the tail end speed is about 2 meters per second.

[0019] The acceleration mechanism 3 and the reduction mechanism 1 are symmetrical in structure.

[0020] Steering mechanism 2 Figure 1 Figure 2 As shown, it consists of a turntable 21, a concave handrail 22, a convex handrail 23 and a driving mechanism 24. The center of rotation is located on one side of the turning, branching or merging direction. The turntable 21 is attached to the tail and head ends of the reduction mechanism 1 and the acceleration mechanism 3. It is a disc made of patterned steel plate. The transmission mechanism 24 is arranged under the turntable 21. The convex handrail 23 is annular and fixed on the top of the turntable 21 with a thin waist cylinder. The concave handrail edge 22 is an arc surface and is driven by friction.

[0021] The concave side armrest 22 of the steering mechanism 2 is as shown in FIG. Figure 3 , Figure 4 As shown, it is composed of an arc surface mounting plate 221, an armrest belt 222, a guide wheel 223, a friction wheel 224 and a tray wheel 225. The arc surface mounting plate 221 is fixed to the outside of the turntable. The armrest belt 222 is shaped by a group of guide wheels. The arc length l of the upper armrest is determined according to the rotation angle θ, that is, l=θ / 360πD, where l is the arc length, θ is the rotation angle (degrees), π is the pi, and D is the diameter of the turntable. The lower transmission section is composed of three guide wheels 223 pressed on two friction wheels 224. The friction wheels 224 and the tray wheel 225 are correspondingly installed on the upper and lower sides of the outer edge of the turntable 21.
