Description

  The present invention relates to a crank device used in a branching device that selects a course of a vehicle.

  For example, there is a tipping device described in Non-Patent Document 1 below as a tipping device that bears the point portion of the branching device. This switch device is composed of a conversion device and a lock device, and is operated by an electric switch 100. Here, the conversion device is for bringing the Tongrel T into close contact with or away from the fixed basic rail R, while the locking device is for maintaining the close contact between the Tongrel T and the basic rail R. (See FIG. 8).

  The electric switch 100 is installed on two sleepers extending outside the gauge (outside between the pair of basic rails R). The electric switch 100 transmits the driving force from the AC motor M, which is a driving source, in the order of a friction clutch, a reduction gear, and a conversion gear with a conversion roller (each not shown), and is operated by the conversion roller 101. Move.

  The motion can 101 moves linearly in a direction perpendicular to the basic rail R as a cam (not shown) connected to the motion can 101 is moved by a conversion roller. The electric switch 100 converts the tongrel T through the switch adjuster 102 connected to the operation lever 101 and the switch rod 103 connected to the tip end of the switch adjuster 102, and the converted tongue Whether the front end of the rail T is in a normal position is checked by the front rod 104, the connecting rod 105, and the locking rod 106. If the front end of the tongue rail T is in a normal position, the operation lever 101 and the locking lever 106 are locked by a cam bar (lock piece) (not shown).

  When the vehicle passes at a relatively high speed, it is necessary to moderate the degree of curvature of each rail, and thus the tongrel T becomes longer. When the long tongrel T is brought into close contact with the basic rail R, even if only the tip of the tongrel T is changed, the base portion of the curve is difficult to be changed, and so-called residual may occur. In this case, a crank device is used to ensure that the long tongrel T is in close contact with the basic rail R. This crank device is disposed along the Tongrel T, and prevents the remaining portion by pressing the curved base portion of the Tongrel T against the basic rail R.

  As such a crank device, there is an escape crank mechanism described in Patent Document 1 below. The escape crank mechanism is installed outside the opposite right or left gauge, and the installation position depends on whether the electric switch 100 is installed outside the opposite right or left gauge. Different. In other words, when the crank mechanism is applied to either the opposite right or left gauge, the operation of the crank mechanism is reversed by simply changing the installation position to the outside of the opposite gauge. It is necessary to disassemble the crank mechanism in order to match the orientation.

  On the other hand, in order to solve the above problems, there is a crank device for a convertible lock device described in Patent Document 2 below as a crank device formed vertically symmetrically. Since the crank device for the convertible lock device is formed symmetrically up and down, the installation position can be changed simply by reversing in any case out of the opposite right or left gauge. In addition, it is a structure that fits in one sleeper.

  However, the above-described crank for a convertible lock device has a structure that can be accommodated in one sleeper, so that the standard is different from the conventional one, such as a narrow pitch of bolt holes when attached to the sleeper. Therefore, it cannot be used for a conventional tipping device. If it is used in place of a conventional crank device, it is necessary to open a new bolt hole in the sleeper to adjust the pitch of the bolt hole, and it is fastened together with the sleeper. It requires complicated work such as the need to remove it.

  The present invention has been proposed in view of the above circumstances. That is, it aims at providing the crank apparatus which can be used for the conventional tipping apparatus by simple work.

  In order to achieve the above object, a crank device according to the present invention is provided with a link mechanism including a driving crank and a driven crank, and is attached to a fixed portion formed on each adjacent sleeper. A fixing member having a sleeper fixing portion formed following the interval of the fixed portion, a main body fixing portion formed inside the interval of the fixed portion, and the link mechanism provided in the front side; A crank body member formed symmetrically with respect to a central axis, the sleeper fixing portion is attached to the fixed portion, and the front side or the back side of the crank body member is the main body fixing portion. It is attached to.

  The crank device according to the present invention is characterized in that a fitting portion that fits each other is formed in each of the fixing member and the crank body member.

  The crank device according to the present invention is characterized in that the shaft portion of the driving crank and the shaft portion of the driven crank are arranged so as to be shifted in a direction intersecting with a longitudinal direction of the sleeper.

  In the crank device according to the present invention, a planar opening that opens to an operating range in which the driven crank operates is formed in the crank body member, and a lid member that closes the planar opening is disposed in the vicinity of the driven crank. The cover member to be connected is connected.

  The crank device according to the present invention is characterized in that the driven crank is formed in a size that closes a space between the driven crank that operates and the planar opening.

  The crank device according to the present invention has the above-described configuration. That is, since the sleeper fixing part of the fixing member is formed following the pitch of the fixed parts of the adjacent sleepers, the present invention is applied as it is to a conventional tipping device. Further, since the crank body member is fixed to the sleepers via the fixing member, the crank body member is attached to and detached from the fixing member, and the crank body member is not required to be attached to and detached from the sleepers. Therefore, it can be used for a conventional tipping device with a simple operation.

  In addition, since the front side or the back side of the crank body member is attached to the main body fixing part, the position of the crank body member can be set by simply reversing the front and back of the crank body member in any case out of the opposite right or left gauge. Can be changed.

  In the crank device according to the present invention, the fixing member and the crank body member are each formed with a fitting portion that fits together. Therefore, the crank body member can be firmly attached to the body fixing portion.

With this configuration, the size of the crank body member is smaller than when the shafts are arranged on the straight line in the longitudinal direction of the sleepers. Thereby, the main body fixing part to which the crank main body member is attached is formed smaller than the sleeper fixing part. Therefore, it is not necessary to fasten the crank body member together with the sleeper, and the crank body member can be detached from the fixing member while the fixing member is fixed to the sleeper. Further, the crank body member can be exchanged with a simple operation.

  In the crank device according to the present invention, a planar opening that opens to an operating range in which the driven crank operates is formed in the crank body member. With this configuration, the operating range of the driven crank is exposed within the range of the planar opening, and the driven crank is exposed regardless of the operated driven crank. Therefore, it is possible to easily check.

  Further, since the lid member that closes the planar opening and the cover member disposed in the vicinity of the driven crank are connected, the planar opening and the vicinity of the driven crank can be shielded by one member. Furthermore, when the front and back of the crank body member are reversed, the lid member and the cover member can also be reversed by a simple operation.

  In addition, since the driven crank is sized so as to block between the driven crank and the plane opening, a part of the operator's body is sandwiched between the driven crank and the plane opening. Not. Therefore, it can be safely checked.
