Description

[Detailed Description of the Invention] [Object of the Invention] (Industrial Field of Application) The present invention relates to a monorail running device for running a monorail installed in a mountainous area, etc., and a ground running device for running on the ground. By a vehicle equipped with
This relates to a monorail type transportation device that transfers between ground and monorail.

(Prior art and problems to be solved) Conventionally, in this type of transportation device, the height, lateral position, and approach angle of the vehicle entering the monorail are determined in front of the monorail, and the correct posture is determined. In order for a vehicle to enter the monorail and engage with the monorail, a guide rail is provided to guide the vehicle. Since the wheels were physically fixed to each other and had different peripheral speeds, at the point where the vehicle first started to move from ground running to the guide rail, ground running by the drive sprocket and running on the guide rail by the auxiliary wheels occurred. The difference in circumferential speed between the drive sprocket and the auxiliary wheel causes slippage between the auxiliary wheel and the guide rail, resulting in wear and a problem in that the transition is not smooth.

[Structure of the invention]

(Means and effects for solving the problem) The present invention interlocks a drive sprocket and an auxiliary wheel via a reduction gear, and also connects this reduction gear to a reduction gear that matches the circumferential speeds of the drive sprocket and the auxiliary wheel. This system is set to a ratio of 1 to 2, so that when the auxiliary wheels of a vehicle traveling on the ground enter the guide rail, the vehicle will proceed at the same speed to eliminate slippage.

(Example) Hereinafter, one example of the present invention will be described in detail with reference to the drawings.

In the figure, the vehicle 1 is configured as follows. That is, the front driving sprocket 3, the rear driven wheel 5, the upper rolling wheel 7, and the lower rolling wheel 9.
An engine cover 15 that houses an engine, a transmission, etc., and a cargo box 17 are arranged side by side on the upper part of the ground traveling device 13, which is equipped with a rubber endless belt 11 that suspends the engine. The vehicle body 19 of the vehicle 1 is provided with a monorail traveling device 23 that engages with a monorail 21 installed on the ground. That is, the vehicle body 19
At the rear of the car, the car body 1 rolls on the monorail 21.

The front part of the vehicle body 19 has engagement holes 33 that roll on the monorail 21 to support the weight of the front part of the vehicle body 19 and that engage with engagement holes 33 that protrude from the top surface of the monorail 21 at predetermined intervals. A vertical drive roller 37 having a dowel pin 35 on its circumference is provided, and is provided so as to be rotatable in forward and reverse directions by a hydraulic motor 39. Further, horizontal rollers 41 and 41 are rotatably supported by brackets 43 that sandwich the monorail 21 on both sides. The drive sprocket 3 has inner and outer side plates 45 fixed to the vehicle body 19,

1 to the drive shaft 53. Drive shaft 5
A flanged auxiliary wheel 55 is fixed to the inner end of the sprocket 3, and the engine power is transmitted to a sprocket 57 fixed to the auxiliary wheel 55 via a chain 59. The reducer 51 is rotatably supported by an internal gear 63 fixed to a case 61 fixed to the side plate 47, a drive gear 65 fixed to the drive shaft 53, and a support plate 67 fixed to the driven shaft 49. The rolling gear 69 meshing with the drive gear 65 transmits power from the drive shaft 53 to the driven shaft 49 at a reduced speed.
The auxiliary wheels 55 engage with guide rails 71, 71 installed on the ground on both ends of the morail 21 and roll on the upper surface. Horizontal rollers 75 are pivotally supported on the outer surfaces of the side plates 47 on both sides via brackets 73 at the front and rear portions, respectively, and the guide rails 7
The approach position of the vehicle 1 is determined by contacting the inner surfaces of auxiliary guide rails 77, 77 installed on the ground on both sides of the tips of the guide rails 1, 71. The reduction ratio of the reduction gear 51 is set so that the circumferential speeds of the auxiliary wheels 55 and the drive sprocket 3 match.

Note that FIG. 8 shows a power system for driving the drive roller 37, and is constructed as follows.
That is, the belt 8 is driven by the engine 79.
1, a variable displacement main pump 83 and an auxiliary pump 85 are rotated. When the engine 79 is at low speed, the auxiliary pump 85 drives the oil tank 8.
The oil in No. 7 is a solenoid valve 89, a check valve 91, and a filter 9.
3. The oil is provided to be returned to the oil tank 87 via the check valve 95, the main pump 83, and the return circuit 97. In this case, the check valve 9 opposite to the check valve 95
9 and the oil supply port 1 of the hydraulic motor 39 from the check valve 95.
A refueling circuit 103 communicating with 01 and a discharge port 10
The same pressure is applied to the discharge circuit 107 connected to the main pump 8, and the hydraulic motor 39 is not driven.

7 to release the hydraulic brake 119 and open the pressure valve 121. While the engine is running at low speed, the oil is returned to the tank 87 from the check valve 95 as described above, and the hydraulic motor 39 does not rotate. Next, when the engine speed is increased or the capacity of the main pump 83 is increased, the oil in the auxiliary pump 85 is
23 is opened and enters the pump 83, and when the flow rate increases from the discharge port 115, the pressure rises and the pilot control valve 111 is automatically switched and closed, and the oil drives the hydraulic motor 39 to rotate. Solenoid valve 89 A
When the cylinder 117 returns to the position, the oil in the cylinder 117 returns to the oil tank 87, and the hydraulic brake 119 is operated to brake the hydraulic motor 39, and as described above, no hydraulic pressure is sent to the hydraulic motor 39.

In the above configuration, when the vehicle 1 traveling on the ground is transferred to the monorail 21, the vehicle 1 enters the auxiliary guide rail 77 from the front. The power of the engine is transmitted from the chain 59 through the reducer 51 to the endless belt 1 by the drive sprocket 3.
1 is rotated. The horizontal rollers 75, 75 on both sides of the vehicle 1 come into contact with the auxiliary guide rail 77, correct their posture, and are positioned for engagement with the guide rail 71. Next, when the auxiliary wheel 55 rides on the guide rail 71, the reduction ratio of the reducer 51 is set so that the circumferential speeds of the auxiliary wheel 55 and the drive sprocket 3 match, so there is a gap between the auxiliary wheel 55 and the guide rail 71. No slips occur. The auxiliary wheels 55 engage with the guide rails 71 to correct and position the height and lateral posture, and the front horizontal rollers 41, 41 engage and roll on both sides of the monorail 21, and are engaged. While the pin 35 is engaged with the engagement hole 39, the drive roller 37 is rolled on the upper surface of the monorail 21 by the drive of the hydraulic motor 39. Subsequently, the rear vertical rollers 25 roll on the monorail 21 to support the rear part of the vehicle 1, and the horizontal rollers 27 roll and clamp the monorail 21 on both sides. When the engagement pin 35 starts to engage with the engagement hole 33, the engagement pin 35 comes into contact with the end surface of the monorail 21 and the engagement position is determined. Because of this drive, the engagement pin 35 does not align with the engagement hole 33, and the drive roller 37 moves while stopping its rotation until the engagement pin 35 aligns with the engagement hole 33. At this time, the solenoid valve 89 is in position B, the hydraulic brake 119 is released, but the engine 79 is running at low speed, and the oil in the auxiliary pump 85 is
Since it passes through the constriction part 113 of the pilot control valve 111 via the main pump 83, the high pressure and low pressure circuits of the hydraulic motor 39 are communicated through the constriction part 113 of the pilot control valve 111, and the engagement pin 35 is engaged. Even if the drive roller 37 is stopped before it aligns with the hole 33, high pressure oil pressure will not be applied to the hydraulic motor 39, and a large load will not be applied to the drive roller 37 and the like. The engagement pin 35 is connected to the engagement hole 33
When the rotation speed of the engine 79 is increased or the capacity of the main pump 83 is increased at the position where the main pump 83 has started to engage, the oil pressure on the discharge side of the main pump 83 increases and the pilot control valve 111 automatically switches. It is then closed and the hydraulic motor 39 begins to rotate normally.

〔Effect of the invention〕

According to the present invention, when the auxiliary wheels of a vehicle that has been traveling on the ground enter the guide rail, the vehicle is made to proceed at the same speed as the ground traveling speed, and the auxiliary wheels are prevented from slipping and wear is prevented. In addition, there is no need to provide a separate hydraulic drive line or a large auxiliary wheel, and the structure can be simple and compact.
