However, in conventional floor type conveyors, a pinion installed on the trolley side is engaged with a rack installed on the guide rail side, and the pinion is rotated by a motor. The trolley was made to run by doing so (for example, US Pat. No. 4,207)
(See Publication No. 821). However, in such conventional conveyors, precision is required for the meshing of the racks and pinions, and it is extremely troublesome to match the pitch of the teeth of the racks that are to be connected to each other, especially at the connecting portion of the guide rail. Therefore, it took time and effort to install the conveyor. In addition, the rack and pinion meshed with each other when the trolley was running, creating noise and creating a poor working environment. Furthermore, when inspecting or repairing the conveyor, workers have to crawl under the guide rails, making maintenance difficult.

OBJECT OF THE INVENTION An object of the present invention is to solve the above-mentioned problems, to enable the installation work of the competition 17 to be carried out easily without requiring much precision, and to avoid the noise caused by the running of the trolley. The environment can be maintained in an extremely quiet state, inspection and repair work can be carried out very easily, and maintenance is easy. It does not allow dirt to get in between it and the power supply rail, and has excellent running performance.Also, since there are no protruding parts on the outer surface of the guide rail, it is easy to access for workers on automobile production lines, etc. We are trying to provide a floor type conveyor with extremely high safety.

In the conveyor (1), when the drive device (25) is turned on, the motor operates and the electric wheels (22) are turned on.
) is rotated. The motor is supplied with electrical energy taken in from the power supply rail (7) via the pantograph (40). When the electric wheel (22) rotates,
The outer peripheral surface of this is the hanging wall part (5b) of the cover rail (5).
) is pressed against the lower edge portion of the motor vehicle (3), so that the electric trolley (3) travels. In this case, 4 pairs each at the front and rear
A pair of driven wheels (4) are mounted on the horizontal wall (2) of the guide rail (2).
a) The cover rails (5) are placed on top of the cover rails (5) by electric wheels (22), a pair of front and rear nipping rollers (33), and a pair of left and right horizontal guide rollers (36).
) are clamped from both the inside and outside sides, the electric trolley (3) reliably travels along the guide rail (2) and cover rail (5). The vibration in the longitudinal direction due to the ups and downs of the guide rail (2) is caused by the swinging mounting plate (17) that holds four pairs of driven wheels (4) of the electric trolley (3) swinging in the vertical plane. In addition, horizontal vibrations are absorbed by the horizontal swinging arm (33) having electric wheels (22) swinging in a horizontal plane against the elastic force of the compression coil spring (32). It is something that will be done. In addition, since the outer circumferential surface of the electric vehicle width (22) is covered with a covering material such as urethane rubber, it is very quiet, and therefore the noise while the electric trolley (3) is running is very small. Article placement part (15) of trolley (3)
A variety of items are placed on the conveyor belt depending on the product being produced, such as automobiles and home appliances.For example, when the object to be conveyed has a complex shape, such as on an automobile production line, it is difficult to support it. In order to do this, a fixture (as shown) may be appropriately attached to the article placement section (15) of the electric trolley (3).
