Description

t

This invention relates to the field of railway transport.

A device for locking and sealing the loading hatches of a freight car is known, comprising a locking mechanism including a movable horizontal link and a locking hook, a pulling mechanism with an adjustable vertical bar and. sealing unit 1.

the disadvantages of the known device are the lack of guarantee that all loading hatches are locked when sealing the mechanism, since leaving one or even several hatches uncovered cannot serve as an obstacle to sealing the mechanism; if one of the hatches overflows with cargo, it can be left unlocked and the mechanism can be sealed; the laboriousness of the operation of locking the loading hatches, since each of the covers has an autonomous locking mechanism and requires an individual lock; the increased metal content of the mechanism, the large detail and laboriousness of manufacture.

The aim of the invention is to increase the reliability of the device in operation.

by preventing the inadvertent opening and enabling the simultaneous locking of all hatches from the transitional platform of the car.

5 For this purpose, the locking mechanism contains two shoulders LYPAGs which are rotatably mounted on the roof of the car in the support brackets, each arm is fixed to one arm

10 is the finger for the figured bracket of the manhole cover, and the second lever arm is also connected by means of a finger with the said movable horizontal pull, which is provided with tie bars, the vertical bar of the tensioning mechanism is equipped with a lever with cheeks hinged on the bracket, the said locking hook is placed between the cheeks of the lever, and in the bar

20 and in the head of the hook are made coaxial holes for the seal.

Claims (1)

Fig, 1 shows a device in plan; figure 2 - node I in figure 1 from the end of the car (the position of the mechanism when the lids are locked); on fig.Z - section aa in figure 2; Fig. 4 shows an interaction unit of a horizontal movable cable gi with a vertical movable bar of the tension mechanism .; Figure 5 shows the tensioning mechanism with the covers closed, side view; on figb section BB in Fig, 5; Fig. 7 shows the tensioning mechanism and the assembly in position with the unsealed lids prepared for opening, side view. The device for locking covers 1 of the hatches consists of a locking mechanism that includes two double-arm levers 2 in the support: brackets 3. At one end of the double-arm lever, a tension finger 4 is rigidly fixed, which interacts with the cracks of 1 hatches, for which figured are installed on the covers Elastic brackets 5, For ease of opening the wings of the shelves, handrails are installed on them b. The lever 2 can rotate in the casing of the shaft 3 relative to the axis of rotation 7. The second end of the lever 2 is movably connected by means of a rigidly mounted pin 8 with a tie collar 9 rigidly mounted on a horizontal movable rod 10. The ha 10 has the possibility of longitudinal movement the holes of the brackets 3 and through the link 11 (see Fig. 4) are pivotally connected to the vertical rod 12. The lower end of the vertical rod 12 has two cheeks 13 with holes through which interaction with the tensioning mechanism and the sealing unit is carried out. The attachment mechanism consists of a tensioning lever 14 pivotally mounted in a bracket 15 rigidly mounted on a rack of a ladder.The lever 14 has two cheeks 16 between which the cheeks 13 of the rod 12 enter and pivotally connected to it through the roller 17. Between the cheek side of the bracket 15 A fixed hook 18 is mounted pivotally with a handle 19 rigidly attached thereto, which is simultaneously the axis of rotation of the hook. In the cheeks 13 of the rod 12 and in the head of the hook 18 there are holes under the sealing wire. The operation of the device is as follows. When the loading is completed, the covers 1 of the hatches are closed and the worker descends to the transition area. A tensioning mechanism is installed on one of the racks of the stairs. A worker, holding the hook 18 in the raised position with his left hand (see Fig. 7), rio turns the lever 14 from top to bottom / moving the bar 12 with the right hand. The rod 12 (FIG. 4, through link 11, carries the horizontal pull 10 along, moving its position in Fig. 3. In this case, the clamps 9 will turn the levers 2, which, turning, with tension fingers, catch the brackets 5 and tightly tighten the lid lids. When the locking device pulls the lever 14 from the position shown in Fig. 7, moves to the lower position, going over the dead center. Since the shoulder of the attachment It remains unchanged, and the projection of the shoulder from the hinge to the point of application of force is almost reduced to zero, at the end of closing the tightening torque increases sharply, which contributes to the tight closing of the lids.At the approach of the lever 14 to the dead point, the locking hook enters between the cheeks 13 of the rod. and, capturing the roller 17 with a tooth, will fix the mechanism and, consequently, the hatches in the locked position. In this case, the holes in the head 18 and the cheeks 13 of the rod 12 will be compatible and provide the possibility of sealing. If one or several loading hatches are overfilled, the cover will resist closing, the lever will not be able to take the lower position until the hatch is cleared of excess cargo, thus preventing the car from being sent with unlocked hatches. In addition, when using this device, all loading hatches are locked at the same time from the transition platform. Claims An apparatus for locking and sealing loading doors of a freight car, comprising: a locking mechanism: a movable horizontal link and a locking hook, a tension mechanism with a movable vertical bar, and a sealing assembly, characterized in that, in order to improve reliability in operation, prevent spontaneous opening and enable simultaneous locking of all hatches from the transitional platform of the car, the locking mechanism contains rotary mounted on the roof of the car and support brackets double-arm levers, one on each arm of which is fixed the tensioning finger for curly brackets hatch as well. The second lever arm is also connected with the finger through the said moving horizontal thrust, which is provided with tie rods, and the vertical bar of the tensioning mechanism is equipped with a lever with cheeks hinged on the bracket, and the said locking hook to the arm is located between the cheeks , and coaxial holes for the seal are made in the rod and in the head of the hook.
