[0002]
[Prior art and problems to be solved by the invention]
In construction using single-rail transporters in mountainous areas, such as communication towers or transmission line towers located in mountainous areas, construction in the winter period is suspended in heavy snowy areas. During maintenance inspections and patrol activities at construction sites, it was necessary to run the transporter.
In addition, in the event of an emergency, it may be necessary to carry in materials and equipment regardless of snow conditions, and for that purpose, regular rail maintenance was indispensable, even during snowfall.
Although it is a single-rail transporter in a mountainous area used in such a background, in heavy snowfall areas, the situation that rails are often buried by overnight snowfall often occurred.
Therefore, the rail is laid at a high position in anticipation of the amount of snow in advance, but the maximum height of the rail is about 1.5M in the case of laying with a general support.
Laying the rails at a high position is a temporary measure against snow accumulation, but it is difficult to work on steep slopes up to 45 degrees, and the topography changes when the snow melts and rains. Taking into account, laying a single rail at a very high position was not the preferred method.
In addition, if the rail is at a high position, it also becomes an obstacle when performing snow removal work manually, leaving a problem.
In this application, the problem of facilitating track maintenance in such a situation is solved by connecting snow removal devices before and after the transporter.
In addition, when adopting a snow removal device, the snow load to be eliminated is detected by a sensor S provided on the connecting bracket C of the snow removal device and the transporter, and transported when the snow removal device senses a load exceeding a predetermined value. The structure is such that the traveling of the machine M is stopped, and damage to the transporter main body and the rail part due to excessive driving force is prevented. Therefore, the problem is solved by passing through a deep snow section while repeatedly performing snow removal operation with an appropriate driving force.
In addition, by placing this sensor, rocks that have collapsed from above during snow accumulation are dammed to the rails, and if the transport machine advances as it is, a dangerous situation that can be derailed or damaged is hidden, and the snow is frozen and the Even if the exclusion load is extremely large and if the rack is engaged with the drive wheel on the lower surface of the rail and the pinion of the drive wheel is damaged and the subsequent operation becomes impossible, the load detection sensor is provided. A safe running state can be obtained by detecting the overload and stopping the transporter.
As another issue, single-rail transporters are often operated without a person except in the case of personnel transport, and fixed position stop devices arranged on rails are provided in the transporter for automatic stop at that time. Since the snow removal device is intended to pass through a position close to the rail of the rail portion, the fixed position stop device collides with the snow removal device and is damaged. This is inevitable, and the present application also solves this problem.
[0003]
[Means for Solving the Problems]
In order to solve the problem in this application, a snow stop device with a sensor is connected to the front part of the vehicle (and also to the rear part if necessary), and a fixed position stop device installed at an unloading point during unmanned operation. In this position, a structure that avoids damage due to the collision is added to only a part of the snow removal device, and the object is achieved without impairing the entire continuous snow removal function.
The schematic configuration of the present application will be described below.
The leading vehicle of a general single-rail transporter M is a motor vehicle M1 equipped with an engine, and a bumper is provided at the most advanced part, but the snow removal device of the present application is to remove this bumper and attach it. is there.
The snow removal device is connected to a power vehicle M1 by connecting a connecting bracket C incorporating an overload detection sensor S to a wheel unit mounted on the rail R with the upper and lower sides of the rail R being tightly attached. A snow removal skirt 5 is installed.
The snow removal skirt 5 is pushed by the following power vehicle M1 and moves forward to eliminate a predetermined portion of snow and facilitate the traveling of the transporter M. The snow of the load is pushed away, and when the load exceeding the set value is detected, the engine is immediately turned off and the traveling of the transporter M is stopped to avoid the inoperable state due to the damage of the transporter M and the rail.
In addition, at the position of the fixed position stop device 6, a part of the snow removal skirt 5 is divided by the guide rail 9 attached to the rail portion in a bypass manner by the upward rotation of the rail 9 so as to pass through the snow removal skirt 5. Thus, damage to the device due to contact of the fixed position stop device 6 is prevented, and continuous snow removal operation can be continued.
[0004]
【Example】
Examples of the present application will be described in detail.
The frame 1 of the snow removal device is formed by combining a square pipe 11 and a plate 12, and on the upper side of the plate 12, small-diameter upper wheels 2, 2 mounted on the main rail R can be rolled on shafts 21, 21. The idle wheel 3, 3 having a slightly larger diameter than the upper wheel is provided to be rotatable by the shafts 31, and the rail is sandwiched from both the upper and lower sides. . The other end of the vertical frame 13 located between the wheels 2 and 3 is provided with rollers 4 arranged on the upper and lower sides of the sub rail SR which divides and supports the load of the transporter in parallel with the main rail R, and has a bowl-shaped configuration in front. The snow removal skirt 5 is fixed.
[0005]
The snow removal skirt 5 has a two-part configuration, and is disposed between the main rail R and the sub rail SR as a fixed skirt portion 51 and is fixed to the frame 1 with a shaft 53.
The fixed skirt portion 51 is fixed to the frame 1 and does not change its position unlike the movable skirt portion 52 described below.
A movable skirt portion 52 is disposed at a position opposite to the fixed skirt portion 51 with the main rail R interposed therebetween.
It is to be noted that the two skirts are roughly divided into two parts. Strictly speaking, as shown in FIG. 1 or FIG. 4, the fixed skirt portion 51 extends from the main rail R, which is the approximate center of the rail portion, to the upper portion of the sub rail SR. Is the snow removal range, and the movable skirt 52 is the snow removal range on the opposite side of the side of the main rail R, so the ratio of the snow removal defense range is about 6: 4.
The movable skirt 52 is pivoted 54 on the frame 1 so as to be pivotable upward, and a roller shaft 55 is integrally projected in a direction opposite to the position of the auxiliary rail SR described above to pivot the guide roller 56. Provide freely. This projecting width protrudes further to the side than the movable skirt 52, and is a length that can ride on a guide rail 9 described later.
[0006]
Further, an auxiliary movable snow removing plate 58 is provided to be pivotally supported 57 at the rear of the movable skirt portion 52 and is connected to the movable skirt portion 52 by a link 59 so as to be integrally formed. Is rotated upward together with the rotation of the movable skirt portion 52.
The position of the auxiliary movable snow removing plate 58 is located behind the movable skirt portion 52 and in front of the fixed position stop lever 10 provided at the front of the motor vehicle, and the movable skirt portion 52 left snow removed during snow removal traveling. The purpose is to prevent the fixed position stop lever 10 from being pressed and malfunctioning due to snow or snow that has collapsed after snow removal. Further, when the movable skirt portion 52 rotates integrally with the rotation of the movable skirt portion 52 to avoid the T-shaped fitting 61 of the fixed position stop device 6, the same operation is performed.
[0007]
As shown in FIGS. 3 to 5, the fixed position stop device 6 is attached to a rail post 7 at a position where it is necessary to stop during unmanned operation or the like with a plate, a bolt, a nut, or the like. The fixed position stop lever 10 of the power vehicle M1 hits the horizontal bar of the motor, and the lever 10 is turned to turn on the switch. This switch cuts off the electric circuit of the engine of the motor vehicle M1 and cuts the fuel with an electromagnetic solenoid valve to stop.
(When moving forward from right to left in Fig. 3)
On the contrary, when moving backward (running from the left side to the right side in FIG. 3), even if the fixed position stop lever 10 hits the horizontal bar of the T-shaped bracket 61, the T-shaped bracket 61 rotates, and the switch of the lever 10 is Has a structure that does not enter.
[0008]
The connecting fitting C comprises a fixing member C1, an outer cylinder C2 connected to the fixing member C1, and an inner cylinder C3 accommodated in the outer cylinder C2. The inner cylinder C3 accommodates a spring C4. One end of the spring C4 is surrounded by a joint surface with the fixing member C1, and the other end is surrounded by a spring contact plate C32 at the inner cylinder end, and passes through the spring shaft C5 and is screwed. The displacement of the spring C4 is set by the combined nut C6. The mutual relationship between the outer cylinder C2 and the inner cylinder C3 to be overlapped is that the guide C31 projecting on the inner cylinder side is inserted into the notch of the guide groove C21 provided on both sides of the outer cylinder end, and the inner cylinder C2 is expanded in accordance with the expansion and contraction of the spring C4. This enables sliding expansion and contraction of the cylinder outer cylinder. The spring contact plate C32 at the end of the inner cylinder C3 is provided with a contact projection C33 for contact with the sensing lever LS1 of the limit switch LS provided on the outer cylinder C2. The end of the fixing member C1 and the end of the inner cylinder C3 are both ends of the connection fitting C. Here, a universal joint J is provided to connect the snow removal skirt 5 and the power vehicle M1.
When the snow removing skirt 5 receives a large load, the spring C4 contracts, the inner cylinder C3 fits into the outer cylinder C2, the contact projection C33 pushes the sensing lever LS1, the sensing lever LS1 rotates, and the limit switch LS Is something that enters.
Specifically, if the snow removal skirt 5 receives an overload due to excessive snow, falling rocks, damage to the rails, etc., the spring C4 in the inner cylinder C3 contracts, causing the contact protrusion C33 and the sensing lever LS1 to contact each other. The switch LS is activated.
[0009]
When the limit switch LS is activated, the electric circuit of the engine is turned off, the hydraulic pressure is stopped, the mechanical brake of the hydraulic motor attached to the drive wheel is activated, the fuel valve with the electromagnetic solenoid is closed, and the motor vehicle is stopped. It is.
In addition, a method in which the operation of the limit switch LS is linked only to the closing of the electromagnetic solenoid valve of the hydraulic circuit and the engine is not stopped can be said to be a convenient method depending on the operation situation.
The initial operating load value of the sensor S is set according to the elasticity of the spring C4 disposed in the cylinder, that is, the number of windings or the amount of displacement, and can be changed according to the strength of the rail, the power performance, and the like. As shown in FIG. 8, the relationship between the spring displacement and the load for setting the load has a certain characteristic within a predetermined range, and it depends on the model of the transporter having various power performances, the laying condition of the rail, etc. It can be applied. In the embodiment of the present application, the maximum is set to about 250 kg, but if a stronger rail and strong power performance can be set, the detection sensor S is also set to a larger load, and the amount of displacement of the spring can be changed. The operation is performed by operating the nut C6 at the end of the spring shaft C5.
[0010]
In addition, as a second embodiment for setting the initial operation value of the sensor S, there is a method in which it is performed steplessly by an electric signal.
As a specific method, as shown in FIG. 10, the load cell RS with the gauge G attached to the connecting metal fitting C is arranged, the pressing force strain due to the load is detected, converted into an electric signal, and an initial set reference value If the value is large, the electric circuit of the engine is turned off, the pressing is stopped, the mechanical brake of the hydraulic motor attached to the drive wheel is operated, the fuel valve provided with the electromagnetic solenoid is closed, and the power vehicle M1 Is stopped or only the hydraulic pressure is stopped to stop traveling.
In this method, the setting of the initial operating load value can be made variable by a setting switch arranged on the operation panel of the driver's seat, and the operating value corresponding to changes in the snow condition during snow removal work, the laying condition of the rail section, etc. The change can be made during the operation, which is more convenient than a method of manually changing the amount of spring displacement performed by stopping the transporter.
[0011]
In the present application, as shown in FIG. 2, after removing the bumper of the transporter M, the universal joint J at the end of the connecting bracket C is attached, and the other end is attached to the attachment 14 of the snow removal device arranged forward.
When mounting the snow removal device on the main rail R, remove the upper wheels 2 and 2 and insert them from the lower side of the main rail R, and insert the removed upper wheels 2 and 2 on the upper side of the main rail R. Then, the snow removal skirt 5 is covered with the bolts and nuts from the top of the frame 1.
[0012]
When the single rail transport device of the present application having the snow removal device having the above configuration is driven, a drive wheel, a hydraulic motor, and a hydraulic pipe located on the bottom surface of the transport device pass between the main rail R and the sub rail SR. No obstacle is installed, and it is only necessary to remove snow continuously with the fixed skirt 51, but in order to enable automatic operation in general, single-rail transporters are generally installed at both ends of the rail or at predetermined unloading stations. A device for stopping the fixed position is provided.
In order to stop at this fixed position, a fixed position stop device 6 is installed in the rail section, a fixed position stop lever 10 is provided on the transporter M, and both are arranged so as to be in contact with each other.
The fixed position stop lever 10 of the present application is attached to the drive wheel unit U of the power vehicle M1 as shown in FIG. 2, and the fixed position stop device 6 is arranged on the left side of the main rail R in the traveling direction. .
Therefore, if the snow in the passing space of the fixed position stop lever 10 of this transporter does not remove snow, the lever will hit the snow in the middle of the route and the travel of the transporter itself will stop. It is necessary.
However, if the snow removal skirt 5 is fixed, it collides with the fixed position stop device 6 installed on the rail and damages it, so that the section where the fixed position stop device 6 is installed avoids the snow removal skirt 5. Is something that will be needed.
In this application, guide rail mounting posts 8 are provided on the rail posts 7 at several places before and after the rail post 7 provided with the fixed position stop device 6, and the guide rails 9 are formed by sequentially inclining the guide rail mounting posts 8 in a bypass shape. Is provided in parallel with the main rail R, the guide roller 56 of the movable skirt portion 52 is moved on the guide rail 9, and the tip of the movable skirt portion 52 is automatically rotated upward about the shaft 54, and fixed. A structure that avoids the position stop device 6 is adopted.
If it demonstrates with FIG. 3, the movable skirt part 52 guide roller 56 of the single rail conveyance machine M which has traveled will be automatically guided on the guide rail 9 from the front of the fixed position stop device 6 and the tip of the movable skirt part 52 will be upward. The guide rail 9 gradually converges to the same height as the R surface of the main rail, and the movable skirt 52 is again in its original position. Snow removal travels in
[0013]
When a load of 250 kgf or more is applied to the snow removal skirt 5 during snow removal, the detection sensor S is activated to stop the transporter M.
When the detection sensor S is activated due to overload, the spring C4 in the connecting metal fitting C is pressed, the detection lever LS1 rotates and the limit switch LS is turned on, the electric circuit of the engine is disconnected, and an electromagnetic solenoid is used. The fuel is shut off by the fuel valve and the mechanical brake of the hydraulic motor is activated.
This load of 250 kgf or more can be inferred in various ways, but if it can be confirmed that the snow is frozen and frozen, it is sufficient to start again at a low speed and gradually remove the snow. When falling rocks are hidden under snow, fallen trees, or when the rails are damaged and deformed and overloaded, the sensing sensor S becomes a probe for these dangerous situations. It is. In this way, if the detection sensor S operates and stops, it is necessary to get off and investigate the snow cover.
[0014]
Also, in the frozen state as described above, as shown in FIG. 12, the snow removal skirt 5 can be mounted at the forefront, and the removable claw can be arbitrarily arranged, and the method of proceeding ice breaking in a situation where the ice is crushed with an ice pick is also effective. There is. In this method, the single-rail transporter itself is laid on a steep slope, and the claws facing diagonally downward will naturally enter under the ice layer as it travels, and the ice that has just been lifted will be lifted. The layer is one that falls sequentially along the slope.
[0015]
FIG. 13 shows a snow removal device attached to the rear end portion of the transporter M, which has the same structure and effect as the snow removal device provided at the front tip, and removes snow when the transporter M moves backward. .
Depending on the mode of operation, the carrying direction of the transporter may be reversed, and this is the implementation situation when the rear end is at the top, and on the long distance laying road, snow removal in the event of heavy snowfall, snow removal on the return road It is suitable when necessary.
[0016]
【The invention's effect】
As described above, by using the transporter provided with the snow removal device of the present application and the rail configuration corresponding thereto, the snow removal work can be performed safely.
In this snow removal work, even if a dangerous situation is hidden if it proceeds as it is, such as falling rocks, fallen trees, etc. during snowfall, when an excessive load is applied to the snow removal device, the detection sensor operates to stop the transporter Therefore, damage to the transporter and the rail portion due to overload does not occur, and in the worst case, a dangerous situation that leads to derailment can be avoided.
In addition, by removing snow, snow does not adhere to the drive wheels, hydraulic motors, piping pipes, etc. that make up the drive wheel unit of the transporter, causing troubles in the electric circuit or hydraulic piping, and stopping at a fixed position. There is no longer a sudden stop when the sensing lever hits the snow.
Further, the snow removal device itself can be fitted and arranged in the middle of the rail, and there is no need for troublesome preparation of removing the transporter itself from the rail and attaching the snow removal device.
