Description

Technical Field

[0001] The present invention relates to a highly versatile track bed finishing machine that can be used as an accessory or attachment for rail vehicles and rail construction machinery.

Background Art

[0002] There is a ballast track in the track bed widely adopted in railways. The ballast track has a structure in which ballast such as crushed stones and gravel is laid, sleepers are arranged on the upper part of the ballast, and rails are laid. In such a ballast track, as a train repeatedly runs on the rail, the rail gradually becomes distorted, so that a track maintenance operation for correcting this rail is required. For example, using a large vehicle called a multiple titan, the rail is lifted, the sleepers are replaced, the ballast is replenished, and the ground is compacted. In such track maintenance work, since a part of the ballast scatters on the fastening part of the rail and on the sleepers, it is necessary to remove this scattered ballast as post-processing. However, since it has been performed manually until now, the work has been very difficult.

[0003] Patent Document 1 discloses a ballast finishing device attached to a first brush, in which the first brush and the second brush are attached so as to spread downward from a rotating shaft, and the second brush spreads more than the first brush. However, in the structure in which the brush is arranged so as to spread downward from the rotating shaft in this way, there is a technical problem that the tip of the brush hardly enters the fastening part of the rail.

Summary of the Invention

Problems to be Solved by the Invention

[0005] The present invention aims to provide a highly versatile track bed grooming machine that can easily remove ballast from rail fasteners and sleepers and can be used as an accessory device or attachment for various track vehicles and track construction machines.

Means for Solving the Problems

[0006] The track bed grooming machine according to the present invention is a track bed grooming machine in a ballast track, and includes a brush device for removing ballast from a rail fastening part or / and a sleeper part, and a holding device for holding the brush device. The brush device has a plurality of brushes whose rotation is controlled, and the holding device has positioning means for positioning the brushes with respect to the rail fastening part. Here, it is preferable that the brush positioning means has any one or more of an angle adjusting means, a height adjusting means, and a left-right direction adjusting means for the tip of the brush with respect to the rail fastening part.

[0007] In the present invention, in the brush device, the rotation of a plurality of brushes is controlled by a hydraulic motor or the like. Further, the holding device holds the brush device so as to be positionable such that the tip of the brush reaches the position of the rail fastening part or the sleeper.

[0008] In railways, two rails are provided in parallel. Preferably, the brush device is arranged in a pair, facing each other from both sides toward the fastening part of the rail with the sleeper for one rail. Therefore, for two rails, when there are a total of four brush devices, two brush devices inside the rails and brush devices arranged outside the left and right rails respectively, it is possible to remove the fastening parts of the left and right two rails and the ballast scattered on the sleepers in one pass. Also, in a ballast track, shoulders that are slightly inclined upward toward the outside of the sleeper are often formed. Therefore, a pair of brush devices for the roadbed shoulder may be provided on both sides to correct the shape of the roadbed shoulder. In this case, if a splash prevention cover is provided outside the brush device for the roadbed shoulder, it can prevent the ballast from splashing outside the roadbed shoulder.

[0009] These brush devices preferably have an angle adjustment means for adjusting the angle in the protruding direction of the tip of the brush so that the ballast can be properly removed. Also, it is preferable to have a height adjustment means for adjusting the height of the tip of the brush according to the height of the fastening part of the rail and the height of the tie. Furthermore, it is preferable to have a left - right direction adjustment means for adjusting the distance from the tip of the brush to a pair of left - right rails.

[0010] In the present invention, it is preferable that a plurality of brushes are arranged around a rotation - controlled rotating shaft, and the direction from the mounting base to the tip of the brush has a predetermined inclination angle toward the rear side of the rotation direction. Furthermore, it is preferable that the brush is made of an elastic material, is detachable from the rotating shaft, and the protruding length of the tip of the brush is adjustable. In this way, when the tip of the brush hits the fastening part of the rail or the tie, it rotates while bending appropriately by the elastic force, and the ballast removal ability is improved.

[0011] In the present invention, when a hydraulic motor is used for the motor that rotation - controls a plurality of brushes, it can be operated by receiving hydraulic supply through a hose pipe or the like from a hydraulic device provided in a rail construction machine such as a hydraulic excavator or a rail vehicle such as a truck. Therefore, the roadbed finishing machine according to the present invention can be used as an accessory device or an attachment of the above - mentioned rail construction machine or rail vehicle, and has excellent versatility.

Effects of the Invention

[0012] The ballast cleaning machine according to the present invention has a brush device that rotates and removes ballast and a positioning means for this brush device. Therefore, by traveling on the rail, it is possible to efficiently remove the ballast. In addition, since a plurality of brushes are arranged so as to be inclined backward at a predetermined angle around the rotation axis, the ballast removal ability is high.

Embodiments for Carrying Out the Invention

[0014] A structural example of the ballast cleaning machine 10 for a ballast track of a railway according to the present invention will be described below based on the drawings, but the present invention is not limited thereto.

[0015] FIG. 1 shows an example of attaching the ballast cleaning machine 10 to a construction machine 1 such as a rail-type hydraulic excavator. This is an example of connecting to the connecting portion 1a provided on the construction machine 1 via the attachment member 11 of the ballast cleaning machine 10. The track bed finishing machine 10 is controlled to move up and down by a main cylinder 1b provided on the main body of the construction machine 1.

[0016] The track bed finishing machine 10 has a holding arm 12 that is link-connected using a pair of auxiliary links 11c on a mounting member 11, and this holding arm 12 is controlled to move up and down by an auxiliary cylinder 11a. The holding arm 12 has a function as a holding device for the brush device. On the main body part of the holding arm 12, there are two brush devices inside a pair of rails 2 and 3, and two brush devices outside this pair of rails, and these are respectively attached via positioning means as will be described later. These brush devices have a common structure, and for convenience, in FIG. 1, they are referred to as the first brush device 21, the second brush device 22, the third brush device 23, and the fourth brush device 24 from the left side.

[0017] In this embodiment, as shown in the front view in FIG. 2 and the plan view in FIG. 3, an example is shown in which a first track bed shoulder brush device 25 and a second track bed shoulder brush device 26 for shaping the shape of the track bed shoulder are attached via auxiliary arms 12a and 12b. These auxiliary arms 12a and 12b are connected to the main body part of the holding arm 12 so as to be foldable upward, and the left and right first track bed shoulder brush devices 25 and second track bed shoulder brush devices 26 can turn 90° upward and be in a storage state.

[0018] In this embodiment, an example is shown in which splash prevention covers 27 and 28 are detachably provided outside the left and right track bed shoulder brush devices. The splash prevention covers 27 and 28 can be slidably adjusted in the length protruding from the holding arm 12 in the left - right direction at the shaft parts 27a and 28a, and can also be removed.

[0019] The brush device has mounting plates (21b, 22b, 23b, 24b) connected to the rotating shafts of hydraulic motors (21a, 22a, 23a, 24a). The mounting plates further have a plurality of shaft-shaped mounting members (21c, 22c, 23c, 24c), and a plurality of brushes (21d, 22d, 23d, 24d) made of elastic materials such as rubber pipes that can be inserted and fixed to the mounting members are detachably attached. As shown in FIG. 4, the plurality of brushes 21d are attached so as to extend in a direction substantially tangential (α) to the rear side of rotation of the mounting plate 21b. It is not necessarily in the tangential direction as long as it is provided on the rear side in the rotation direction of the rotating shaft and extends with a predetermined inclination angle. In this embodiment, six brushes are attached in a direction substantially orthogonal to the rotating shaft. There is no limit to the number of brushes. Since the plurality of brushes are provided with a predetermined inclination angle on the rear side in the rotation direction and arranged in a direction orthogonal (right angle) to the rotating shaft in this way, when the tip of the brush hits the fastening part of the rail as shown in FIG. 5, it rotates while bending appropriately. Although the illustration of the sleeper is omitted in FIG. 5, the ballast scattered on the sleeper can also be removed.

[0020] Next, the positioning means of the brush device will be described. A left-right direction positioning member 14 is attached to the holding arm 12, auxiliary arms 12a, 12b. The left-right direction positioning member 14 is slidably adjustable in the left-right direction by, for example, a combination of a long hole 14a in the left-right direction and a fixing member 14b such as a bolt as shown in FIG. 4. A height direction positioning member 15 is attached to the left-right direction positioning member or the auxiliary arm. For example, as described with reference to FIG. 6, it is slidably adjustable in the vertical direction by a combination of a long hole 15a provided in the vertical direction in the mounting part and a fixing member such as a bolt. An angle adjusting member 13 is attached to the height direction positioning member. For example, as described with reference to FIG. 2, it is composed of a combination of a rotation center hole 13c, an arc-shaped long hole 13a provided outside thereof, and a fixing member 13b such as a bolt. In this embodiment, although an example of the combination of the long hole and the fixing member has been described, the present invention is not limited thereto.

[0021] The plurality of brush devices provided in the roadbed grooming machine 1 are adapted to be operated by the hydraulic supply of a hydraulic device provided in a construction machine or the like. As described with reference to FIG. 3, the main relay valve 31 is connected to a hydraulic device provided in the main body of the construction machine by a hydraulic hose. The operating oil for the auxiliary cylinder 11a is supplied from the main relay valve 31, and each brush device is connected to a hydraulic motor thereof by a hydraulic hose via an auxiliary relay valve 32. By adopting a configuration in which the hydraulic motors of the respective brush devices are connected by hydraulic hoses via the auxiliary relay valve 32 and the main relay valve 31, it is possible to switch the connection method of the hydraulic hoses between the hydraulic motor and the relay valve of a predetermined brush device, so that the hydraulic system can be switched to a series connection or a parallel connection.

[0022] When the roadbed grooming machine according to the present invention is operated by receiving the hydraulic supply of the rail-mounted vehicle, in addition to being used as an accessory of the construction machine 1 shown in FIG. 1, it can also be used as an attachment of a construction machine 1 such as a hydraulic excavator as shown in FIG. 7, or as an attachment that can be mounted on a rail vehicle as shown in FIGS. 8(a) and 8(b). Therefore, it has high versatility. When used as an attachment, as shown in FIG. 9, only a pair of wheels for rail travel may be provided on one side. FIG. 9(a) shows a state in which the attachment is attached to a vehicle or the like, and FIG. 9(b) shows a case where the attachment is detached from the vehicle. When the attachment is structured with only one-sided wheels in this way, if the attachment is detached from the vehicle, the attachment will tilt and be prevented from self-running on the rails.
