Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a roof moving device for an M1 base sliding freight car. More specifically, the present invention relates to a roof moving device for an M1 base sliding freight car. More specifically, the present invention relates to a roof moving device for an M1 root sliding freight car. - To provide a roof-sliding freight car whose roof can be easily moved manually from the roof or from the ground, and which can be pushed down and the roof can be left in a fully open position. That is.

Conventionally, the roof sliding freight car described in Japanese Patent Publication No. 85-17959, for example, does not have an auxiliary device such as a spring. It is necessary to pull the operating handle with a large amount of force to raise the roof, and when the roof is closed, the roof falls directly onto the roof rail at an accelerated rate, causing a large impact and resulting in a lack of safety during work. It was desired.

Since a sliding roof freight car is operated by one worker from the long roof or from the ground against the blindness of the roof, it is extremely important to create a mechanism that operates with as little input as possible. In order to displace the entire roof, conventional slide-roots of this type have been made of sheet metal or have complicated special equipment installed to allow the roof to be opened and closed.

The present invention has a simple structure that makes opening and closing operations easier,
Furthermore, the present invention aims to provide a roof sliding freight car made of other materials without being limited to light alloy.

Another object of the present invention is to provide a roof-sliding freight car that can be easily converted to either underground or ground operation depending on the work situation by simply replacing some parts. It is in.

Still another object of the present invention is to provide a novel device to the slope rail at the end of the vehicle so that the roof remains stationary in the fully opened position and prevents the wheel support arm from shifting in the rotational direction at the beginning of the opening operation. Our goal is to provide a freight car with a sliding roof.

The present invention will be explained below with reference to figures showing one example. Figure 1 (&) is an overall perspective view of a sliding roof freight car equipped with an operating handle on the roof, with each roof shown in a closed state. 1 is the car body, 2 is the number of houses, 8 is a roof that can be moved above the other roof, 4 is a long structure on both sides of the roof 8, 5 is a cross-section installed in the center of the upper part of the car body 1 - cedar side brace , both ends of which are connected in an arched manner to the upper edges of the center of the side structures on both sides of the vehicle body, and are located below the adjacent edge portions of the roof, thereby maintaining the rigidity of the vehicle body l and reducing the gap between the adjacent edge portions of the roof. Prevent rainwater from entering the car. 6 is a footboard provided on the upper center of the roof 8, 7 is a wheel support arm that is rotatably pivoted on the #i slope on the outside of the long strip near the center of the vehicle body on each roof, and has a wheel at its tip; 8Fi these The operator can lift and pull the wheel support arm 7 using the operating handle that connects the left and right wheel support arms 7.

It is a mechanism that works in the direction of pushing up through the wheels that ride on the top.

Figure 1 Φ) is an overall perspective view of a roof-sliding freight car equipped with an operating lever from the ground, showing the same closed state as in Figure 1 (4), with an operating lever 8tIA stop connected to the wheel support arm. It is exactly the same as the above except that an operating lever 18 for operating the wheel support arm from the ground is provided at the car end of the roof instead of 9, and a connecting side 14 is provided to connect these and transmit the operation. be.

In the states (e) and (b) of Fig. 1, the wheel support arm 7Fi
On the other hand, the wheels 9 at the end of the car fall into the inclined part of the roof rail 1O, and the spring 1ill also falls into the tension spring 12.
Since it is stretched out and tilted in a V-shape, the long side facing the roof sits directly on the roof rail 10 on the upper part of the vehicle body, and also has a structure in which it meshes with the inner rising member of the roof rail 10. This prevents rainwater from entering the interior of the car and prevents the roof from moving forward, backward, left or right.

A latch hook, 82B is a release pull bar for removing the latch 26 from the latch hook 2 and allowing the operation lever 1B to rotate; 80Fi is a drive shaft that transmits the rotational force of the operating lever 18 to the drive arm z9, and 81 is a bearing that rotatably supports the drive shaft 8° and the drive arm B9 on the outer surface of a long strip. The end O shape of the rail 10 is exactly the same as that shown in FIG. 8 (-).

As described above, in the w1 stage of the present invention, one roof 8 is raised from the closed state shown in Figs. 1, 2, and 8 to the state shown in Fig. 4, and moved to the open position shown in Fig. m5. When using the operating handle on the roof, a worker on the footboard 6 on another roof pulls the operating handle 8 on the roof that he or she wishes to open. Next, when using the operating lever on the ground, the worker on the ground pulls the operating lever 18 provided at the end of the roof that he or she wishes to open. Then, as shown in FIGS. 4(&) and (b), in both cases, both the central and central portions of the roof rise upward. In addition, Ii#- is the horizontal distance between the wheel 17 and the bin 16 of the wheel support arm 7 that was lying down, and the dimension that the wheel 17 has rolled up the slope of the roof rail lO toward the bottom. Tabu Tona Sho, Mata, Wheel 17
The amount of displacement in the direction of the roof is caused by the length of the wheel support arm 7 that rotates along the slope of the roof.
It rises to a position where it does not come into contact with the closed roof and auxiliary equipment shown in the dashed line and in FIG. In this process, the springs 1llllllll help the rotation of the wheel support arms 7 by the tension of the tension springs 12 and are drawn together via the auxiliary wheels 19, causing them to rotate and push up the roof. As shown in FIG. 7(a), the auxiliary wheels 19 are positioned at one point iiiIillIf when the roof has finished rising.
It is maintained in a position where it does not touch the closed roof and both corner devices shown in Figures M and 7, and the entire load of the roof is carried only by the wheels 17 as it is moved upward from the roof rail IO. The relationship between the roof pushing force W of the single spring FI411 and the tensile force P of the tension spring 120 during the roof rising process is shown in Figure 8, and linearly attenuates as the roof rises. The tensile force P of the tension spring 1g is converted into a force pushing up the roof by approximately 1 g due to the change in the lodging angle of the spring arm 11.
I! The force required to move the operating handle S against one of the roots is approximately 17B N175 without this device.

When the roof is closed, the wheels 9 supported by fixed bearings at the other end of the roof are located in recesses 88 provided at the ends of the roof rails 10, as shown in FIG. For,
Wheel support that is 41 movements on one side of the roof! ! 1170, so that the roof does not shift in the longitudinal direction during the rotation and completes its rise at the fixed position.

In addition, in the case of the operating lever on the ground, the rotating operating lever 18 is fixed in this position by the latch 26 biting into the latch latch 27, and is supported for vomiting via the connecting pull rod 14 connected to the upper end with a pin. The @ wheel support arm 7 that holds the arm 7 is held at a position slightly before the dead center even when the roof has been raised, and the connecting pull rod 14 always applies force only in the direction of tension where it receives the component of gravity of the roof. Because it is supported by a small diameter object, the force can be transmitted.Also, by pulling the release pull rod 38, the latch 26 and the latch latch 87 are removed.
By releasing the engagement with the wheel support arm 7 and removing the holding force of the wheel support arm 7, the roof supported by this can be lowered.

On the other hand, in the operation handle on the roof, the wheel support arm 7 is directly moved by the operation handle 8, so that the wheel support arm rotates to a position slightly beyond the dead center and is self-retained.

If the operating handle 8 or the operating lever 1B is further pulled from this state, the wheels supported by the bearings provided at the end of the roof near the vehicle end will escape from the recess 28 provided at the end of the roof rail IO. After running on a slightly horizontal path, roll up the slope 22 and the preliminary slope 21, and after reaching the horizontal path 10 of the roof rail, move to the wheel support arm at the other end. Wheel 1 installed in
7 to support the four corners of the roof and move horizontally on the roof rail 10 until it is fully opened as shown in FIG. In this process, the other spring arm 11 provided near the end wheel 90 acts in the same manner as described above, helping the wheel 9 to climb up the inclined rail 10 against the weight of the roof. During the entire event, wheel 17, which was located near the single center of the roof, was @5.
As shown in the figure, the end surface of the roof is in contact with the stopper 24, so the roof is constantly pressed against the stopper by its own weight, preventing the roof from escaping when left open. This is to prevent this.

When moving and closing an open roof, - In the case of operation on the foundation soil, the worker who has climbed onto the closed roof pushes the operating handle S, and the wheels 9 at the end are moved to the roof rail. 1
Go down the slope rail z2 of 0, concave l! When it moves to position 1I52B, this end of the roof lowers to the closed position tIt and stops against a stopper provided on the upper part of the wall of the vehicle body 101E. If the operating handle 8 is pushed further from this state, the wheel support arm 7 will rotate beyond the dead center, and the roof will lower to a predetermined position and sit horizontally on the roof rail 1o, entering the closed state. In this case, when the worker on the ground moves the operating lever 1B in the closing direction, the latch 26 provided at the top of the operating lever 18 engages with the latch latch z7 fixed on a long strip. moves on one base line lO, and descends and stops at a predetermined position in the same manner as described above. In this state, control lever 1
When the release pull bar 2B provided at
7, the operating lever 1B and the drive arm z9 on the other side become free, so the wheel support arm 7 connected to it via the connecting rod 14 collapses due to the overlapping of the roof, and this side of the roof also falls to the specified position. When the lever 1B is lowered to the position shown in FIG. The operating lever 18 can also have a removable structure. In this case, the upper end and lower part of the lever are separated and inserted into one body only when opening and closing the roof.
It should be stored separately at all times.

To convert the roof operating handle to a ground operating lever, remove the bin 16 and remove the wheel support arm 7 and the operating handle S from the wheel support arm holder together with the wheel 17. Refit the wheel support arm holder 15 with the bin 16. Also, replace the operation lever holder 85 provided at the other end of the roof.
A drive shaft 29 is inserted into the bearing 81, and an operating lever 18 with a latch s6 and a release pull bar 28 is attached to one end, and a drive arm 89 is attached to the other end, and the upper end of each is connected to the wheel support arm 7. Connected by a connecting rod. Furthermore, the footboard 6 on the roof is unnecessary when operating on the ground. In addition, when converting a ground control lever to a roof control handle, the above procedure can be performed in reverse. Can be constructed.

As described in detail above, according to the present invention #1, a pair of oppositely inclined spring arms are rotatably pivoted with bins near both front and rear ends of both long beams of the roof, and the spring arms A spring is applied to each other and a tensile force is applied to the roof, and when the roof is moved over the other roof, the roof is pulled into a position where it can be easily moved on the roof or by hand from the ground, and then pushed down. Can be done. In addition, we provided a slope with a gentle slope in front of the sloped end of the roof rail, and also provided a horizontal path at the end of the slope, and provided a recess on the horizontal path for the wheels to lock. When the roof is closed, the wheels supported by fixed bearings are located in the recess, so even when the wheel support arm rotates during the first movement of raising the roof, the roof remains stable without shifting during rotation. The ascent can be completed in position.

In particular, the roof opening/closing mechanism of the present invention has a simple structure and is easy to operate to open and close the roof, prevents surface areas caused by rapid falls, and is economical because it is not limited by the material of the roof, making it a significant invention.
