Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a device for supplying a friction resistance agent such as sand to a rail of a crane or the like, and more particularly to a device for preventing skewing or derailment due to slip or the like during traveling of the crane.

[0002]

[Prior art]

 Wheels such as cranes are of double-flange type for the purpose of preventing wheel removal, and therefore have high frictional resistance with the rails. In addition to the rapid wear of the flange and rail due to this friction, if the frictional resistance force is biased to one side of the crane, the crane may skew and cause braking failure, and if the skew becomes excessive, it may derail. In order to reduce this frictional resistance, a lubricant such as oil is applied to the side surface of the rail. However, since this lubricant transfers to the top surface of the rail, skewing of the crane and derailment cannot be prevented.

In addition, when the crane is installed outdoors, the rail may get wet with rainwater and the frictional resistance may be excessively reduced, so that the crane may be skewed or derailed in the same manner, which is extremely dangerous. At the same time, if the wheels are removed, the axles will be damaged and a great deal of effort will be required to restore them.

[0004]

[Problems to be solved by the device]

 The object of this invention is to evenly spread an appropriate amount of sand on the rails of a crane or the like, thereby appropriately increasing the frictional resistance of the rails and preventing the crane from skewing or derailing.

[0005]

[Means for Solving the Problems]

 A first invention for solving the above-mentioned problems is to provide a tank containing a friction resistance agent such as sand, a wheel rotatably attached to a lower portion of the tank, and a connection extending laterally connected to the tank. The wheel has a member having an upper part protruding into the inside of the tank, a peripheral surface abutting against a lower end of a side wall of the tank, and a plurality of recesses formed on the peripheral surface. It is a resistance agent supply device.

A second invention is a tank for containing a friction resistance agent such as sand, a wheel rotatably attached to a lower portion of the tank, and a bracket extending laterally connected to the tank. And a connecting member disposed above the bracket with a gap therebetween, the wheel has an upper portion projecting into the inside of the tank, a peripheral surface abutting against a lower end of a side wall of the tank, and a plurality of recesses on the peripheral surface. The bracket and the connecting member are connected to each other by a suspension rod on the tank side and connected via a spring on the non-tank side, and a lever for adjusting the distance between the bracket and the connecting member.

【Example】

 Hereinafter, an embodiment in which the present invention is applied to a crane will be described in detail. FIG. 1 shows a state in which a frictional resistance agent supply device 1 of the first invention is attached to a saddle 2 of a crane. 2 shows an overall view of the friction resistance agent supply device 1, and FIG. 3 shows a side view (perspective view) of a tank 3 containing a friction resistance agent such as sand (hereinafter, sand will be described as an example). FIG. 4 shows a front view of the tank 3.

The tank 3 for storing sand has a sand charging port 4 at its upper end, and as shown in FIGS. 3 and 4, the side wall 5 is formed in a hopper shape and has an opening 6 at the lower end. A sand-seeding wheel 7 is rotatably attached to the lower portion of the tank 3, and the sand-seeding wheel 7 has an upper portion protruding into the inside of the tank 3 from an opening 6 of the tank 3 and slidably contacting with a lower end of a side wall 5 of the tank. So as to contact each other, and a large number of recesses 8 are formed on the peripheral surface. Reference numeral 9 is a rubber seal member that is in contact with the sand-spreading wheel 7 and bolted to the side wall 5 to seal the sliding surface.

A laterally extending mounting member 10 is connected to the upper portion of the tank 3 shown in FIG. 2. The tip of the mounting member 10 is shown in FIG. 5 on a supporting member 19 fixed to the saddle of the crane. So that they are connected by the insertion pin 17.

Next, the operation of this device will be described. The tank 3 is charged with a required amount of sand S, and the attachment member 10 is connected to the support member 19 of the saddle with the insertion pin 17. At this time, the sand sowing wheel 7 is placed on the rail 18 of the crane. When the crane travels in this state, the sand-spreading wheel 7 rotates as the crane travels. As shown in FIG. 3, the sand-seeding wheel 7 has a large number of depressions 8 formed on its peripheral surface. Therefore, the sand that has entered the depressions 8 is carried out of the tank as the sand-seeding wheel 7 rotates, and the rails are removed. It is possible to drop on the upper surface of 18 and evenly spread the sand on the rail upper surface. When the crane stops, the sand sowing wheel 7 also stops and the sand does not drop. In addition, when the rail is not sowed while the crane is traveling, the tank 3 is lifted, and a hanging strip (not shown) provided on the supporting member 19 of the saddle is hung on the hanging hand 20 to support the sand. The sowing wheel 7 separates from the rail 18. Therefore, even if the crane runs, the sand-seeding wheel 7 does not rotate and the sand does not drop. In this way, by sowing the sand as needed, it is possible to obtain the frictional resistance necessary for the traveling of the crane and prevent the crane from skewing and derailing. When changing the amount of sand to be sown, replace it with another sand shaving wheel 7 having a different number or size of the recesses 8.

Although the recess 8 is circular in this embodiment, the recess 8 may have another shape such as a slit shape instead of the circular shape, and the shape of the recess can be changed appropriately. In the above-mentioned embodiment, the friction force of the sand-spreading wheel to the rail is obtained by the weight of the sand stored in this device and the tank. The sowing wheel may slip on the rails. In addition, since the wheels of the crane are of double flange type and sometimes sway during traveling due to its own weight, the tank sways during sand shaving, and the flange of the sand shaving wheel comes into contact with the side surface of the rail and wears. In addition, the sand-spreading wheel may fall off.

FIGS. 6 to 8 show an embodiment of a second device which solves the above-mentioned problems, and members having the same names and functions as those of the embodiment of the first device are the same as those of the first embodiment. The description of its structure and operation is omitted.

In the figure, a bracket 11 extending laterally is connected to the rear portion of the tank 3 by two slide pins 21 and 21, and a connecting member 12 is arranged above the bracket 11 with a gap therebetween. ing. The bracket 11 and the connecting member 12 are connected on the tank side by a suspension rod 13 and on the other side by a connecting rod 15. The suspension rod 13 penetrates the connecting member 12 and is movably suspended on the connecting member, and the horizontal pin 22 supported by the bracket 11 penetrates the lower portion of the suspending rod 13. The connecting rod 15 is suspended by a shaft 23 (FIG. 8) fixed to the connecting member 12 so that it can move in an arc, and a coiled spring 14 is loosely fitted through the bracket 11 so that a double spring for adjusting the spring force can be obtained. The nut 24 is screwed.

A pair of levers 16, 16 are pivotally attached to the connecting member 12 by a shaft center rod 27, and an abutting rod 25 is provided at a lower end between the levers 16 and 16, so that the bracket 11 is closed. Is in contact with. A handle 26 is provided at the upper end. As a result, the spring 14 applies a force to draw the bracket 11 and the connecting member 12 together. The levers 16 and 16 may be pivotally attached to the bracket 11, and the contact rod 25 may be provided below the connecting member 12.

Next, the operation of this device will be described. Similar to FIG. 5, the connecting member 12 is connected to the supporting member 19 fixed to the saddle by the insertion pin 17. When sanding the rail 18, when the lever 16 is actuated in the direction of arrow A as shown in FIG. 7, the repulsive force of the spring 14 causes the tank 3 to descend and the sand wheel 7 to press against the rail 18. When the crane travels in this state, the crane shakes for the above reason. Rolling is solved by the tank 3 moving along the slide rods 21, 21. Further, the vertical movement of the crane or the rail is solved by the expansion and contraction of the spring 14. Further, the tilting of the crane is solved by the repulsive force of the spring 14 and the circular movement of the connecting rod 15. In this way, it is possible to prevent abrasion of the sand-spreading wheel flange due to slipping and swinging of the sand-spreading wheel 7, and also to prevent derailment. When the rail is not sowed while the crane is traveling, if the lever 16 is operated in the direction of arrow B as shown in FIG. 8, the spring 14 is compressed around the suspension rod 13 and the tank 3 rises. Then, the sowing wheel 7 is separated from the rail 18.
