Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a moving mechanism for a tamping device which comprises a plurality of tamping devices for packing and solidifying ballast ballasts of a track, and movably supporting these tamping devices on a gantry. Is.

[0002]

2. Description of the Related Art Conventionally, ballasts have been laid on the track to support the sleepers on the rails. When trains run on rails many times, the weight and vibrations of the trains cause ballasts to move and push down sleepers. And
The sleepers are suspended by the rails, and the pumping action causes the sludge phenomenon and the drop of creases, which impairs the ride comfort and safety of the train. Therefore, it is necessary to periodically push the ballast under the sleeper to solidify it and perform the tamping work to push the sleeper up to a normal position. A tamping device has been conventionally used as a device for performing such tamping work. This tamping device basically includes a pair of front and rear beaters that vibrate by a vibration motor, and an opening and closing means such as a cylinder for opening and closing the front and rear beaters to move up and down.

An example of such a tamping device will be described below with reference to the drawings. In the figure, T is a sleeper and U is a rail. As shown in FIG. 6, the tamping device A of this example has a tamping tool unit 1 provided with a vibration motor 2 and a beater 3 in front of and behind a support base 4.

On the front and rear surfaces of the support base 4, there are provided a guide member 5 provided in the vertical direction and a slider 6 supported so as to be able to move up and down with respect to the guide member 5. A support member 8 of the tamping tool portion 1 is attached to the slider 6 via a link 7, and the tamping tool portion 1 is supported on the support member 8 via a connecting means 9. That is, the base of the link 7 is rotatably attached to the support shaft 6a provided on the slider 6, and the tip of the link 7 and the support member 8 of the tamping tool unit 1 are rotatably connected by the support shaft 8a. There is.

The slider 6 is provided with a pair of stoppers 10 and 11 for restricting the rotation range of the link 7 with respect to the slider 6. The support member 8 of the tamping tool unit 1 is provided with stoppers 12 and 12a that regulate the rotation range of the tamping tool unit 1 and the link 7. The base of the lifting cylinder 13 is attached to the support base 4. The tip of the piston rod of the lifting cylinder 13 is connected to the slider 6.

Further, such a tamping device A is
A pair of sleepers T are provided on the left and right in a direction parallel to the sleepers T so that ballasts near both ends of the sleepers T can be solidified at the same time. In the left and right tamping devices A, when the inside and the outside of the rail U are fixed, when there is a guardrail or an obstacle, the width can be adjusted in the branch section.
A moving mechanism is provided. The moving mechanism of the tamping device A will be described below. That is, as shown in FIG. 7, the gantry 14 is vertically erected in front of or behind the vehicle body that can travel on the rails U. This stand 1
4, a guide rail 15 is provided horizontally in the left-right direction. A pair of left and right slide plates 17 are supported on the guide rails 15 by slide bearings 16. The slide plate 17 is connected to a drive unit (not shown) and is provided so as to be slidable along the guide rail 15. And the slide plate 1
Since the support base 4 of the tamping device A is fixed to 7, the left and right tamping tool parts 1 are configured to be slidable in the left and right direction (longitudinal direction of the sleepers).

The tamping work by the tamping device having the above-mentioned moving mechanism is performed as follows.
That is, first, the left and right slide plates 17 are moved by the drive unit to move the left and right tamping tool parts 1 to predetermined positions. For example, the positions of the left and right tamping devices A need to be changed depending on whether the ballast on the outside of the rail U is compacted or not. After completing such alignment,
The slider 6 is lowered using the lifting cylinder 13, and the beater 3 is inserted into the ballast so as to be sandwiched from the front and rear of the sleeper T while vibrating the beater 3 using the vibration motor 2. As a result, vibration is applied to the ballast, and the front and rear beaters 3 are opened and closed by sandwiching the sleeper T by the opening / closing means.
The ballast is pushed under the sleeper T so that the ballast is stuck to the bottom of the sleeper T so that the ballast is firmly attached.

[0008]

However, the moving mechanism of the conventional tamping device having such a structure has the following problems. That is, as shown in FIG. 7, as for the width of the gantry 14 and the guide rail 15, first, the movable distance of the slide plate 17 (S in the figure,
It is necessary to secure). The pair of left and right slide plates 17 are provided so as to be movable along the guide rails 15 on the same straight line. Therefore, a dead stroke (indicated by X1 in the drawing) is required for the gantry 14 and the guide rail 15 in consideration of the collision of the left and right slide plates 17. Furthermore, the pedestal 14
Also, it is necessary to provide a margin for preventing the slide plate 17 from coming off at both ends of the guide rail 15, and a dead stroke (indicated by X2 in the figure) is also provided here.
Is required. Therefore, in order to movably provide the pair of left and right tamping devices A, the width of the gantry 14 and the guide rail 15 must be at least (X1 + X2 + S) × 2. For this reason, the entire device becomes large,
A large vehicle is required when the apparatus is stored or transported, particularly when the tamping apparatus is loaded on the vehicle and transported to a work site, which is not space efficient. Further, since the movable distance of the slide plate 17 is limited within the width of the gantry 14, the adjustment of the interval of the tamping device A is also limited within the width of the gantry 14.

The slide plate 17 is required to be mounted with a tamping device A having a vibrating beater 3 and to be surely supported. However, the slide plate 17 has a planar shape, and in order to secure a movable distance, the slide plate 17 is required. Since the size of 17 cannot be increased, there is a problem in strength. If the slide plate 17 is made thicker to cope with this, the size of the entire apparatus increases.

The present invention has been proposed in order to solve the above-mentioned problems of the prior art. The first object of the present invention is to reduce the size and weight, and to achieve space efficiency during storage and transportation. It is to provide a good tamping device moving mechanism.

A second object of the present invention is to provide a moving mechanism of a tamping device which can secure a large ratio of the movable distance to the width of the gantry of the tamping device and can be applied to various intervals.

A third object of the present invention is to provide a moving mechanism for a tamping device, in which the slide member is light in weight and has a strength capable of withstanding vibrations and can reliably support the tamping device.

[0013]

In order to achieve the above object, the invention according to claim 1 has a gantry having a constant length in the longitudinal direction of the sleeper, and guide means provided on the gantry. A pair of slide members supported by the pedestal via the guide means so as to be slidable in the longitudinal direction of the sleeper, and drive means for moving the slide members,

One of the slide members is provided on one side surface of the two side surfaces facing each other in the longitudinal direction of the track of the gantry, and the other slide member of the pair of slide members is the gantry. A support frame is provided on the other side surface of the two side surfaces facing each other in the longitudinal direction of the track, and the other slide member is provided with a support frame projecting in the longitudinal direction of the track by overcoming the mount and the one slide member. The tamping device is provided on the support frame, and the one slide is provided between the other slide member and the support frame. Wherein the gap portion id member is inserted in the longitudinal direction of the sleepers is formed.

According to a second aspect of the invention, in the moving mechanism of the tamping device according to the first aspect, the tamping provided on the pair of slide members when the pair of slide members are slid in a direction of separating from each other. It is characterized in that the pair of slide members are long in the longitudinal direction of the sleepers such that the device protrudes from the longitudinal direction of the sleepers in the gantry.

According to a third aspect of the present invention, in the moving mechanism of the tamping device according to the first or second aspect, the slide member is a rectangular or U-shaped frame, and the one of the slide members is the same. The connecting portion with the tamping device and the support frame of the other slide member are rectangular mounting frames.

[0016]

The operation of the present invention having the above construction is as follows. That is, according to the first aspect of the invention, the pair of slide members are provided on the opposite side surfaces of the gantry, and the other slide member is provided so as to be insertable into the gap portion of the one slide member. Therefore, when storing or transporting, slide the slide members so that they approach each other,
By inserting the other slide member into the gap of the one slide member, the entire width of the slide member can be overlapped in the longitudinal direction of the track. In this way, corresponding to the state where the pair of slide members are superimposed on each other,
By reducing the size of the gantry, it is possible to save space in the longitudinal direction of the sleepers, which is convenient for storage and transportation.

According to the second aspect of the invention, the tamping device is installed above the track when performing the tamping work. Then, the drive unit is operated to move the pair of slide members in the direction in which they are separated from each other, and the tamping device is positioned in correspondence with the space between the tracks. The slide member is formed to be long, and the tamping device projects from the longitudinal direction of the sleepers on the gantry when the slide members move in a direction in which they are separated from each other. Therefore, the ratio of the movable range of the tamping device to the width of the gantry can be increased as compared with the conventional configuration in which the tamping device can move only within the width of the gantry. Even if the width of the frame is shorter than the conventional one, the same movable range can be secured.

According to the third aspect of the present invention, since the slide member itself and the connecting portion of the slide member with the tamping device are formed as a rectangular parallelepiped frame, the weight can be reduced while maintaining the strength to support the tamping device. Can be planned.
