Abstract

PURPOSE:To positively make start-running and brake-stopping of a transport electric car by mounting motors for driving horizontal axis wheels simultaneously, respectively, in front and rear trolleys supported possible of running on a single guide rail through the respective horizontal axis wheels. CONSTITUTION:In a monorail, transport electric car 1, at least two front and rear trolleys 2, 3 are supported possible of running in a single guide rail 7 through horizontal axis wheels 9, 10, respectively. A suspending means 4 for a transporting object 5 is disposed in both the trolleys 2, 3. Motors 15, 16 for driving the horizontal axis wheels, respectively, are mounted in both the trolleys 2, 3 so that the respective horizontal axis wheels 9, 10 are rotated simultaneously. That is, by means of power and control signals supplied through respective collection units 18, 19 from power supply and signal lines 17, both the motors are driven simultaneously. Accordingly, start-running and brake-stopping of a transport electric car 1 are each made positively, thereby raising the operation factor.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a monorail type transportation train used particularly in a machine shop.

[0002] This type of transport train is provided with at least two front and rear trolleys, each of which is supported by one guide rail so as to be able to travel via a horizontal axis wheel, and a suspended object to be hung on both trolleys. The conventional one is equipped with a motor for rotationally driving a horizontal axis wheel pivotally supported by the trolley only in one trolley, and the conventional one is provided with a thrust of a power trolley equipped with this motor. It was configured to run a train.

However, when this monorail type transportation train is used for transporting an object to be transported in a machine factory, since the atmosphere in the factory contains oil mist, oil mist is formed on the wheel rolling surface of the guide rail. Adhesion caused the frictional resistance of the only horizontal axis wheel for traveling to drop significantly, which sometimes caused the wheel to easily slip when starting or braking, which made normal operation impossible. In order to solve such problems, measures such as enclosing the train travel route with a vinyl sheet, improving ventilation, and disconnecting the train travel route from the bad atmosphere with an air curtain were considered, but cost However, it was not practical because the effect was low.

[0004]

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned conventional problems, the features of which will be described with reference numerals of embodiments described later in parentheses. As shown, the monorail type transportation train of the present invention has at least two front and rear trolleys supported by one guide rail (7) via horizontal shaft wheels (9, 10), respectively.
(2,3), and a monorail type transport train including means (4) for suspending an object to be transported, which is suspended on both trolleys (2,3), and Each of them is equipped with a motor (15, 16) that drives a horizontal driving wheel (9, 10) pivotally supported by each of these trolleys, and the horizontal driving wheels (9, 10) for both front and rear trolleys are mounted. Is characterized in that they are driven to rotate simultaneously.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings. In FIGS. 1 and 2, reference numeral 1 denotes a transport train of the present invention, which is a pair of front and rear trolleys 2. 3 and
Conveying object suspending means 4 suspended on both trolleys 2 and 3
It has and. The transported object suspending means 4 is composed of an openable / closable hanger 6 for suspending the transported object 5, but may have any other structure.

Both trolleys 2 and 3 have the same structure and are mounted on an upper rail portion 8a of a guide rail 7 having an I-shaped cross section which is erected at an appropriate height above the floor surface. 9, 10, a vertical shaft roller 11, 12 for precession that sandwiches the upper rail portion 8a from both left and right sides, and a vertical shaft roller 13, 14 for precession that sandwiches the lower rail portion 8b of the guide rail 7 from both left and right sides. , The horizontal wheel 9,
Motors 15 and 16 for rotationally driving 10 are provided, and current collecting units 18 and 19 laid on the side surface of the guide rail 7 are in sliding contact with the power supply and signal lines 17. 20, 21
Is a speed reducer mounted on each trolley 2, 3, in which the horizontal shaft wheels 9 and 10 are attached to the output shaft and the motors 15 and 16 are directly connected to the input shaft.

The transport train 1 configured as described above is
Each trolley 2, by the power and the control signal supplied from the power supply and signal line 17 via the power collection units 18, 19.
By simultaneously driving the motors 15 and 16 of the trolleys 3 and driving the horizontal shaft wheels 9 and 10 of the two trolleys 2 and 3 in the same direction at the same speed, the vehicle travels forward or backward along the guide rails 7. Can be run. By the traveling of the train 1, the transported object 5 supported by the hanger 6 which is the transported object suspending means 4 can be transported along the guide rail 7.

Since the electric motor 1 is driven by the two motors 15 and 16 mounted on both trolleys 2 and 3, these motors 15 and 16 are mounted on a conventional one-wheel drive electric motor. The capacity of one motor can be about half, but in some cases, the capacity of a conventional motor can be used. Further, as in the case of handling a long transported object 5, a driven trolley for preventing collision of the transported objects can be connected to at least one of the trolleys 2 and 3 via a load bar. .

[0009]

According to the monorail type transport train of the present invention which can be implemented as described above, each trolley is provided with the traveling horizontal axis wheels of two trolleys before and after suspending the object suspending means. Since the trains are driven by rotating the motors installed at the same time, the horizontal axis wheels and guides of both trolleys can be used even when used in an atmosphere containing oil mist, such as in a machine factory. As long as no slip occurs at the same time with the rail, the train can be started and run reliably. When the vehicle is stopped, the horizontal wheels of both trolleys are braked, and the train is braked by the frictional resistance between these two horizontal shaft wheels and the guide rails.
The braking can be stopped at a predetermined position reliably and accurately without slipping.

Therefore, it becomes unnecessary to take the conventional measures such as enclosing the traveling route of the train with a vinyl sheet or disconnecting the traveling route from the surrounding bad atmosphere with an air curtain.
Moreover, it is possible to always run and stop the train reliably and improve the operating rate.
