Description

[Detailed description of the invention] (Industrial application field) The invention relates to a gravel lifting device that lifts and leveles the gravel on the track floor.

(Prior art) Conventionally, as this kind of gravel scraping device, there is
There is one disclosed in Japanese Patent Publication No. 3121.

In this machine, sliding grooves are formed in the vertical direction on both sides of the main frame attached to the back of the rail motor car. At the same time, this sliding metal fitting is moved up and down by a wire operated by a winch via a pulley provided at the upper end of the main frame, and a pin is inserted into an adjusting hole of the sliding groove to determine the vertical position of the raking wing. On the other hand, a telescopic rod having a large number of adjustment holes is provided between the track body and the raking wing, and a pin is inserted into the hole to maintain the telescopic state to determine the degree of expansion of the raiding wing. Is what it is.

(Problems to be Solved by the Invention) According to the above-mentioned prior art, the raking wings for scraping the gravel on the track rail can only move in two directions, up and down and opening and closing movement, with respect to the rail motor car. Since the hoisting wings are set in advance so as to hang down obliquely with respect to the track motor car, it is possible to adjust only the amount and position of the gravel picked up on the track rail.

Therefore, by changing the amount of gravel scooped by the raking wing, the flow of gravel scraping is appropriately adjusted,
In addition, the angle of the gravel surface and the width of the roadbed cannot be appropriately adjusted, and when the work location changes and the shape of the angle or width of the gravel surface of the roadbed changes, the gravel scraping work according to the shape is performed. There was a problem that made it difficult.

The present invention has been made in view of such circumstances.
An object of the present invention is to make it possible to easily perform a gravel scraping operation by appropriately adjusting a raking wing in accordance with a change in the shape of a trackbed of a track bed even if the shape of the trackbed changes.

(Means for solving the problems) In order to achieve the objectives described above, the measures taken by the present invention are:
A gravel lifting device attached to the left and right sides or any one side of a stand (1) erected at the rear of the track motor car (M), wherein the mounting member (23) attached to the track motor car (M) side. A raking wing (3) is axially mounted on the raking wing (3).
The lifting device (3) is opened and closed about the fulcrum shaft (21) with respect to the orbital motor car (M) by a hydraulic device (22) installed between the mounting member (23) and the mounting device (23). ), And a lifting blade opening / closing mechanism for determining a gravel-raising position and a mounting plate (27) fixed to a bracket (25). The mounting member (23) is rotated laterally about its pivot (28) by a hydraulic device (24) installed between the mounting member (25) and the mounting member (23) to move the mounting member (23) laterally. A horizontal angle adjusting mechanism that adjusts the angle and determines the flow of gravel scraping, and a horizontal shaft (16) having the bracket (25) fixed to the tip thereof are set up in parallel at predetermined intervals. Along the two longitudinal axes (11) and (11), the fixed ends of the brackets (25) are arranged outside the track motor car (M) and laterally supported, The horizontal shaft (16) is rotated in the front-rear direction by a hydraulic device (29) vertically installed along the vertical axis (11) to adjust the vertical angle of the raking wing (3), and the gravel surface is adjusted. A vertical angle adjusting mechanism for determining the angle of a rising blade, and an upper and lower 2 rotatably fitted to two vertical guide rods (5) (5) arranged at a predetermined interval on the gantry (1). The two longitudinal axes (11) and (11) are supported in parallel by a pair of connecting rods (8) (8) and (8) (8), and the longitudinal axes (1)
The longitudinal axis (11) (11) is set by a hydraulic device (18) installed between the vertical guide rod (5) and the vertical guide rod (5) in a positional relationship facing the streak.
And a raising wing extension mechanism for moving the horizontal shaft (16) in a horizontal direction with respect to the track motor car (M) to adjust the horizontal extension position of the raising wing (3) to determine the width of the roadbed. , Two pairs of connecting rods (8) supporting the vertical axes (11) and (11).
(8) and (8) and (8) are moved up and down along the vertical guide rods (5) and (5) by a hydraulic device (6) erected on the gantry (1) to move the raising blade (3). It is characterized in that it comprises a raising and lowering mechanism for adjusting the vertical position and determining the gravel lifting amount.

(Effect) If the rake wing opening / closing mechanism expands the rake wing leftward or rightward with respect to the orbital motor car and holds it at a predetermined angle with respect to the motor car, the gravel scraping position is obtained. Is determined (see the arc arrow in FIG. 7). Next, the raising and lowering mechanism of the lifting blade is moved up or down to a predetermined height by a lifting blade vertical mechanism, and if it is held at a predetermined height position with respect to the gravel on the track floor, the gravel is removed. The scraping amount is determined (sixth illustration). Then, by the raising wing overhanging mechanism, the raising wing whose gravel rake amount is determined is moved to the left or right, and is held at a predetermined lateral overhang position with respect to the gravel on the railroad track. Is determined (see the straight arrow in FIG. 7). Next, the raking wing lateral angle adjusting mechanism rotates the raking wing having the determined roadbed width in the left or right lateral direction of the track motor car, and sets the lateral angle with respect to the gravel on the track floor. If the angle is adjusted, the amount of gravel scooped by the raking wing changes, and the flow of gravel lifting changes (No. 8).
Illustrated). Further, by the lifting blade vertical angle adjustment mechanism, the lifting blade whose lateral angle has been adjusted is rotated in the vertical direction in front of or behind the orbital motor car, and the vertical angle with respect to the gravel on the track is set to a predetermined angle. , The gravel surface angle is adjusted (FIG. 9).

Therefore, the order of determining operations such as the raising posture and the raising position of the lifting blade is not limited to the above-described order, and the order of each mechanism is not limited.
If the track motor car is operated after the operation is determined through the steps, the gravel on the track is scraped up to a desired shape and leveled.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

The orbital motor car (M) has a gantry (1) erected by a mounting column (4) at the rear, and a movable frame (2) for constituting a gravel scraping device described later on both left and right sides or one side of the gantry. Is arranged.

The gantry (1) is erected by mounting columns (4), and two pairs of vertical guide rods (5) for mounting the movable frame (2) are provided over the positions deviated to the left and right sides of the upper and lower rods. And a movable frame (2) attached to their vertical guide rods (5).
Are mounted to be vertically movable. The gantry (1) has a hydraulic cylinder (6) provided downward through the upper rod between the pair of vertical guide rods (5), and the movable cylinder (2) is operated by operating the hydraulic cylinder. Is configured to be moved up and down along the vertical guide rod (5).

The movable frame (2) is provided on both left and right sides or one side of the gantry (1) (in the illustrated example, on both left and right sides of the gantry). It is a structure for determining the lift amount and the track width.

Hereinafter, a description will be given of a set of movable frames (2). As shown in FIG.
A total of four movable tubes (7) are fitted and attached, and a connecting rod (8) is protruded laterally on one side of each movable tube (7).
First rotating pipes (9) are fixed to the ends of the connecting rods (8), respectively, and the upper and lower connecting rods (8) are connected by a vertical continuous rod (13) to connect the upper and lower movable pipes (7). Maintain at predetermined intervals.

A sliding pipe (14) is disposed between the upper and lower movable pipes (7), and is mounted through a pair of vertical guide rods (5). Two rotating pipes (10) are arranged, and the first and second rotating pipes (9) and (10) have a vertical axis (1).
1), the first rotating pipe (9), the second rotating pipe (10), and the longitudinal axis (11) are supported on the vertical guide rod (5) by the connecting rod (8).

The upper and lower movable pipes (7) are connected to each other by a first horizontal connecting rod (12), and the horizontal mutual spacing of the movable pipes (7) is equal to the mutual spacing of a pair of vertical guiding rods (5). Let me maintain the interval. On the other hand, the second rotating pipes (10) are connected to each other by a second horizontal connecting rod (15), and the horizontal interval between the vertical axes (11) is made equal to the mutual interval between the pair of vertical guiding rods (5). The horizontal rod (16) is rotatably supported laterally below the second horizontal connecting rod (15) and between the second rotating pipes (10) below the second horizontal connecting rod (15).

Furthermore, when a receiving rod (17) for connecting the downward hydraulic cylinder (6) provided on the gantry (1) is installed between the sliding pipes (14) and the hydraulic cylinder (6) is operated, When the upper or lower movable tube (7) is pushed up or down, the first rotating tube (9) connected to the movable tube (7) by the connecting rod (8), Second rotating pipe (10) sandwiched between pipes (9), and both rotating pipes (9)
The vertical axis (11) penetrating through (10) moves up and down,
Since the connecting rod (8) is connected by the vertical connecting rod (13), the vertical movement on the first rotating pipe (9) side operates simultaneously with the vertical movement on the movable pipe (7) side. Thus, the vertical position of the raking wing (3) is adjusted to constitute a raking wing vertical mechanism for determining the gravel rake amount.

Next, as shown in FIGS. 1 to 5, the second rotating pipe (1) located outside the orbital motor car (M) in a positional relationship facing the muscles.
0) and the sliding tube (1) located inside the motor car (M)
4) or between the second rotating pipe (10) and one end of the receiving rod (17) having the same positional relationship facing the muscle, a hydraulic cylinder (18) is erected. (18)
When the first rotating pipe (9) and the second rotating pipe (1) are operated,
0), the vertical axis (11) and the like are supported by a connecting rod (8) extending from a movable tube (7) fitted to a pair of vertical guiding rods (5), and rotate in the left-right direction. The left and right movement on the rotating pipe (9) side is caused by the fact that the second rotating pipe (10) is connected by the horizontal connecting pipe (15) and the horizontal shaft (16) is supported by the horizontal shaft. The one rotating pipe (9), each second rotating pipe (10), each vertical axis (11), and the horizontal rod (16) move parallel to the left or right like a link motion, and scrape up. The wings (3) are extended laterally with respect to the gravel (b) on the track as shown by the straight arrows in FIG. Therefore, for example, if the overhang position of the scraping plate (3) is changed from the position indicated by the two-dot chain line to the position indicated by the solid line in FIG. 7, the roadbed width is changed, and the solid line position of the scraping plate (3) is determined. With this, the right and left overhang position of the uplift wing (3) is adjusted, and a uplift wing overhang mechanism that determines the width of the roadbed is formed.

The scraper wing (3) is a member for scraping the gravel (b) previously laid on the track floor and leveling the ground, and forms a concave shape on the inner side of the track motor car (M) in a concave shape.
A scraping plate (19) is attached to the lower side to form a cross-sectional shape that facilitates scraping of the gravel (b).

As shown in FIGS. 3 and 4, a fulcrum shaft for left and right rotation is attached to the rear end (one end on the rear side of the orbital motor car) of the mounting base (20) mounted on the upper surface of the wing (3) as shown in FIGS. (21) is erected, and a mounting member (23) mounted on the horizontal shaft (16) is mounted on the fulcrum shaft (21). One end of a hydraulic cylinder (22) for left and right rotation is pivotally mounted on a part (near one end of the unit side), and the other end of the hydraulic cylinder (22) is mounted on the mounting member (23). Thus, when the hydraulic cylinder (22) is operated, the raking wing (3) opens and closes in the lateral direction of the orbital motor car (M) about the fulcrum shaft (21). Thus, a sweeping blade opening / closing mechanism that adjusts a predetermined spread degree to determine a gravel scraping position is configured.

In addition, one end of a hydraulic cylinder (24) is pivotally mounted on the upper surface of a mounting member (23) pivotally mounted on the fulcrum shaft (21) as shown in the second, third, and fourth illustrations on the raking wing (3), The middle of the hydraulic cylinder (24) is rotatably mounted on a bracket (25) fixed to one end of the horizontal shaft (16) (the outer end of the track motor car), and the mounting The bracket (26) protruding from the lower surface of the member (23) is connected to the pivot (28) of the mounting plate (27) protruding downward at one end (the end) of the horizontal rod (16).
To pivot. This allows the hydraulic cylinder (24)
As shown in FIG. 8, the rake wing (3) rotates in the lateral direction of the track motor car (M) about the pivot (28) as shown in FIG. The amount of the gravel (b) adjusted and scooped by the raking wing (3) is changed. That is, if the scraping plate (19) is in the solid line position shown in FIG. 8 or in a more upright position, the gravel (b) is scooped, and the flow of the gravel (b) is good and the amount is large. In the two-dot chain line posture, the gravel (b) comes to be covered, and the flow becomes worse. Therefore, a lifting angle lateral angle adjustment mechanism that determines the flow of gravel lifting is configured.

Further, as shown in FIG. 4, the horizontal shaft (16) has a front side or a rear side (one side which is a front side or a rear side of the railroad motor car) and a second horizontal direction. A hydraulic cylinder (29) for vertically turning the raking wing (3) is installed vertically along the same side of the connecting rod (15). When the hydraulic cylinder (29) is actuated, the horizontal shaft (16) rotates in the front-rear direction, so that the rake wing (3) swings in the front-rear direction of the track motor car (M), and The vertical angle with respect to the gravel (b) is adjusted. Accordingly, as shown by a two-dot chain line in FIG. 9, when the raking wing (3) rotates toward the front side, the gravel (b) raises an obtuse angle, and at the same time, widens the roadbed, thereby raising the raft. Conversely, if (3) is rotated to the rear side (not shown), the gravel (b) is raised at an obtuse angle, and at the same time, the roadbed width is narrowed, and the gravel surface angle is adjusted. Thereby, a vertical angle adjustment mechanism of the wing wing (3) which determines the surface angle of the gravel (b) by adjusting the vertical angle of the wing wing (3) is constituted.

Each of the above hydraulic cylinders (6), (18), (22),
(24), (29), etc. are configured such that hydraulic pressure is supplied by driving a hydraulic pump (not shown) via the PTO of the orbital motor car (M).

In the drawing, reference numeral (30) denotes an auxiliary wing frame protruding from the front side of the gantry (1) (the rear side of the railroad motor car), which is on the same side as the side on which the scraper wings (3) are disposed. Auxiliary wings (31) are provided to be rotatable to the left and right with respect to the auxiliary wing frame (30) and can be opened and closed. use.

(Effects of the Invention) Since the invention is configured as described above, the lifting wing is opened and closed,
Not only vertical movement but also vertical and horizontal rotation and lateral overhang operation can be performed, and by appropriately adjusting the lifting position of the lifting blade by these various operations, the lifting position of gravel, It is possible to arbitrarily determine the amount of rise, the width of the bed, the angle of the gravel surface, and the flow over the scrape.

Therefore, even when the work place changes and the shape of the trackbed of the track floor is different, the gravel wing can be easily adjusted by appropriately adjusting the raking wing in accordance with the change in the shape of the trackbed, Compared to the conventional gravel scraping operation, the work can be performed more efficiently and a consistent finish can be obtained.
