JPH03143765A - Buffer stop for running vehicle - Google Patents

Abstract

PURPOSE:To easily and certainly stop a running vehicle by protruding and recessing a link means by the movement of a moving means, and bringing a stopper close to or apart from a track and a wheel in a buffer stop in which the stopper is installed between the track and the wheel to fix the vehicle. CONSTITUTION:To install a buffer stop to a wheel 2 on a track 1 in a vehicle stopped in a determined position, a moving means (e) is first moved in the direction leaving the track 1. One end of an arm 8 in a side wall base 6 is pushed by a plate (t2) connected to the moving means (e), and a slide link 5 connected to the arm 8 is slid with a pivot pin P1 as an axis, and a stopper S disposed on the top end of the link 5 is installed between the track 1 and the wheel 2. Hence, the stopper S can be easily and rapidly attached and removed without depending on input and a device having a complicated structure.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a car stop suitable for use when temporarily stopping a vehicle running on a rail.

(Prior art) Equipment, etc. that moves the rail between the front and rear wheels of the vehicle in a direction perpendicular to the running direction of the vehicle when a vehicle running on rails is temporarily stopped at a predetermined location or after the vehicle is stopped. In this case, a wedge-shaped stopper called a hem shoe was usually installed between the wheels and the rails to prevent the vehicle from moving from its stopped position or the wheels of the vehicle falling off.

(Problems to be Solved by the Invention) Incidentally, the wedge-shaped stopper as described above is installed manually by the operator operating the vehicle, and has the following problems.

In other words, if the stopper is left behind or placed incorrectly, there is a risk that the vehicle will move spontaneously or the wheels will fall off the rails, and when placing the stopper, there is a risk of accidents such as people getting caught in the vehicle. . There are also known car stop devices that are driven by air cylinders,
Not only does such a device have the disadvantage that it becomes inoperable because it is easily damaged by metal or flying debris during processing when the vehicle is a towed car, for example, but the device itself is very expensive. It is an object of the present invention to propose a relatively simple mechanism for securing a vehicle without requiring manual installation or using expensive equipment.

(Further Means for Solving the Problems) The present invention provides a bollard that fixes a running vehicle by installing a damper between the wheels and the rails of a running vehicle running on a rail, in which a pivot pin is attached to a bracket fixed to a base. A base arm is installed that is swingably connected through the base arm, and a slide link with a stopper at the tip is connected to one end of this base arm through a pivot pin, and is fixed to a side wall base that is perpendicular to the base. A side wall base arm that is swingably connected to the side wall pace bracket through a pivot pin is installed, one end of this side wall base arm is connected to the other end of the slide link through the pivot pin, and the other end is connected to the other end of the slide link through the pivot pin. This is a stop for a running vehicle that is connected to a moving means that can move forward and backward in a direction that intersects the track.

Now, Figures 1 (a), (b), (c) and (d) show a bollard according to the present invention, and number 1 in the figures is a rail.
Although not shown, another rail 1 is provided in parallel with this rail 1. Further, 2 is a wheel of the traveling vehicle, 3 is a bracket fixed to the base b, 4 is a base arm swingably connected to the bracket 3 via a pivot pin p1, and 5
is a slide link having a stone bar S at its tip portion, and this slide link 5 is connected to the base arm 4 via a pivot pin p2. 6 is a side wall base perpendicular to the base b; 7 is a bracket fixed to the side wall base 6; 8
is a side wall base arm swingably connected to the bracket 7 via a pivot pin ρ3; one end of this side wall base arm 8 is connected to the other end of the slide link 5 via a pivot pin p4; It is removably linked between engagement plates C++12 of a moving means e whose end is movable forward and backward in a direction intersecting the track 1. In addition, the above-mentioned moving means e may be of a mechanism to move as far to the left side as viewed from the page, and when such moving means e is applied, the linkage between the arm 8 and the plate 2 must be released when the stopper S is attached. become.

(Function) In order to attach a bollard to a vehicle stopped at a predetermined position on the rails, the moving means e is first moved in a direction away from the rails 1 at that position. Then, the other end of the side wall base arm 8 is pushed to L2 by the plate connected to the moving means e,
The slide link 5 connected to this arm 8 has a pivot pin p
The stopper S is installed between the wheel 2 and the rail 1 by sliding it around the axis as shown by the broken line in the figure, and the stopper S provided at the tip of the stopper is installed between the wheel 2 and the rail 1, so there is no need to manually install the stopper. There is no need to use complicated and expensive equipment. FIG. 2 shows another example of a car stop according to the present invention. In the example shown in FIG. 1 above, the slide link 5 is connected to the bracket 3 via the pivot pin, but the bracket 3 is provided with an elongated opening 0 that engages with the pivot pin,
A similar effect can be obtained by sliding the pivot pin together with the link 5 through the opening.

The above-mentioned moving means e may be any existing equipment that inevitably moves the vehicle in a direction away from the rails when it stops. Furthermore, by constructing the side wall base arm 8 from spring steel, there is an advantage that even if the moving means e moves back too much, the arm 8 can be deflected and damage to the device can be avoided.

(Effects of the Invention) Thus, according to the present invention, the stopper can be easily and quickly put on the underwear without using human power or a device with a complicated structure. Moreover, since the structure is simple, the cost involved can be reduced as much as possible.
