Description

本発明は、鉄道レールの頭頂面を切削して軌道回路用の溝を形成するレール削溝機に関する。   The present invention relates to a rail grooving machine that forms a groove for a track circuit by cutting a top surface of a railroad rail.

一般に、鉄道レールでは、車両の有無を感知するために、レール頭頂面に形成された軌道回路を常時通電可能な状態に維持することが求められる。しかし、閑散線区などでは、レール頭頂面の錆によって軌道回路が通電不能となる場合がある。この場合、頭頂面をレール長手方向へ連続的に切削して溝を形成し、この溝にステンレス溶接を行って、軌道回路を通電可能な状態に修復する必要がある。   Generally, in order to detect the presence or absence of a vehicle, a railroad rail is required to always maintain a track circuit formed on the rail top surface in a state where current can be energized. However, there may be a case where the track circuit cannot be energized due to rust on the rail top surface in a quiet line area. In this case, it is necessary to continuously cut the crown surface in the longitudinal direction of the rail to form a groove, and perform stainless steel welding on the groove to restore the track circuit to a state where electricity can be applied.

この種の削溝作業は、従来、保線作業員による手作業で行われていた。作業員はグラインダーを携帯し、レールに沿って歩行しつつ頭頂面に溝を切削していた。なお、特許文献１には、レールの切損や亀裂の拡大を防止するための溝をレール頭頂面に自動切削する「溝穿設装置」が記載されている。この装置は、２本のレール上を走行可能な車台上に溝切りカッター、レール面研磨機、これらの動力源を装備している。   This type of grooving operation is conventionally performed manually by track maintenance workers. The worker carried a grinder and cut a groove on the top surface while walking along the rail. Patent Document 1 describes a “groove drilling device” that automatically cuts a groove on the rail top surface to prevent rail breakage and crack expansion. This apparatus is equipped with a grooving cutter, a rail surface polishing machine, and a power source for these on a chassis that can travel on two rails.

ところが、従来の削溝作業は、手作業で行われていたので、作業員に多大な労力と負担がかかるうえ、作業速度が遅く、溝の加工精度も低いという問題点があった。また、特許文献１の装置をステンレス溶接用の溝加工に転用することも考えられるが、従来装置は２本のレールを跨ぐほどの大型機械であるため、機械の搬入出作業を含めて工事が大掛かりとなり、閑散線区での使用に不向きであった。   However, since the conventional grooving work is performed manually, there is a problem in that it takes a lot of labor and burden on the worker, the work speed is slow, and the groove machining accuracy is low. In addition, it is conceivable to divert the device of Patent Document 1 to the groove processing for stainless steel welding. However, since the conventional device is a large machine that straddles two rails, construction work including loading and unloading work of the machine is required. It became a large scale and was unsuitable for use in a quiet line area.

そこで、本発明の目的は、１本のレール上で簡便に使用でき、レール頭頂面に溝を迅速かつ高精度に切削できるレール削溝機を提供することにある。   SUMMARY OF THE INVENTION An object of the present invention is to provide a rail grooving machine that can be easily used on one rail and can cut a groove on the rail top surface quickly and with high accuracy.

A roller 38 as a vibration damping member is supported at the tip of the bracket 39 so as to be rotatable around a horizontal axis. A contact plate 40 is erected on the holder 29 so as to face the vibration control roller 38, and the vibration of the electric grooving tool 23 during cutting is reduced in the rail width while the vibration control roller 38 is in contact with the contact plate 40. Deterred from the direction.

図１、図５に示すように、切削圧調節機構２５は、電動溝切り工具２３のディスク２８に切込み方向の荷重を印加するおもり部材４２と、おもり部材４２を着脱可能に支持するネジ付きロッド４３を備えている。ネジ付きロッド４３の下端はジョイント４４を介してディスク２８近傍の工具ボディ２７に結合され、ネジ付きロッド４３の上部におもり部材４２を支承する支承部４５が設けられている。   As shown in FIGS. 1 and 5, the cutting pressure adjusting mechanism 25 includes a weight member 42 that applies a load in the cutting direction to the disk 28 of the electric grooving tool 23, and a threaded rod that detachably supports the weight member 42. 43. The lower end of the threaded rod 43 is coupled to the tool body 27 in the vicinity of the disk 28 via a joint 44, and a support part 45 for supporting the weight member 42 is provided on the upper part of the threaded rod 43.

At the time of cutting, the wing screw 47 is arranged above the horizontal rod 46 (see FIG. 3), and the disk 28 is pressed against the rail top surface 2 with a load having a magnitude corresponding to the number or total mass of the weight members 42. It has become.

次に、鉄道レール１の頭頂面２に溝４を切削する方法について説明する。まず、上記のように構成されたレール削溝機１を作業現場に搬入する。このとき、図３に鎖線で示すように、予め前後の案内輪１８，２１と電動溝切り工具２３をそれぞれレール頭頂面２よりも上方の非作用位置に配置しておく。こうすれば、案内輪１８，２１やディスク２８に妨げられることなく、車台１２をレール１上に容易に設置することができる。   Next, a method for cutting the groove 4 in the top surface 2 of the rail 1 will be described. First, the rail grooving machine 1 configured as described above is carried into a work site. At this time, as indicated by a chain line in FIG. 3, the front and rear guide wheels 18 and 21 and the electric grooving tool 23 are previously arranged at the non-operating position above the rail top surface 2. In this way, the chassis 12 can be easily installed on the rail 1 without being obstructed by the guide wheels 18 and 21 and the disk 28.

続いて、図３に実線で示すように、案内輪１８，２１をレール１の左右両側に配置するとともに、ディスク２８をレール頭頂面２の上に降下させる。そして、この状態で作業員は電動溝切り工具２３を起動し、ディスク２８を回転させ、手押しハンドル１５を押し、車台１２をレール１２上で前進させ、図４に示すように、ディスク２８によってレール頭頂面２に溝４を連続的に切削する。   Subsequently, as shown by a solid line in FIG. 3, the guide wheels 18 and 21 are disposed on both the left and right sides of the rail 1, and the disk 28 is lowered onto the rail top surface 2. Then, in this state, the operator activates the electric grooving tool 23, rotates the disk 28, pushes the push handle 15 and advances the chassis 12 on the rail 12, and as shown in FIG. A groove 4 is continuously cut in the top surface 2.

この切削時には、ホルダー２９がディスク２８をレール幅方向の所定位置に保持するとともに、制振ローラ３８が電動溝切り工具２３の水平振動を抑止するので、レール頭頂面２に溝４を高精度に加工することができる。また、おもり部材４２による切削圧を加減することで、溝４の切込み深さを容易に調節することができるうえ、図４に鎖線で示すように、水平調整部材３２の位置調整によって溝４の切削位置をレール幅方向に調整することもできる。   At the time of cutting, the holder 29 holds the disk 28 at a predetermined position in the rail width direction, and the vibration control roller 38 suppresses horizontal vibration of the electric grooving tool 23, so that the groove 4 is formed on the rail top surface 2 with high accuracy. Can be processed. Further, by adjusting the cutting pressure by the weight member 42, the depth of cut of the groove 4 can be easily adjusted, and the position of the groove 4 can be adjusted by adjusting the position of the horizontal adjustment member 32 as shown by a chain line in FIG. The cutting position can also be adjusted in the rail width direction.

図５に示すように、溝切り作業に伴いディスク２８が摩耗した場合は、ディスク２８の径方向寸法の変化に追従してホルダー２９が下方へ傾動するので、ディスク２８を常時最適な切削圧でレール頭頂面２に切り込ませることができる。また、ホルダー２９が傾動したときには、制振ローラ３８が当接板４０と接触を保って回転するので、ディスク２８の摩耗に関わりなく制振機能を継続的に発揮することができる。   As shown in FIG. 5, when the disk 28 is worn due to the grooving operation, the holder 29 tilts downward following the change in the radial dimension of the disk 28, so that the disk 28 is always kept at the optimum cutting pressure. The rail can be cut into the top surface 2 of the rail. Further, when the holder 29 is tilted, the vibration control roller 38 rotates while maintaining contact with the contact plate 40, so that the vibration control function can be continuously exhibited regardless of the wear of the disk 28.

なお、本発明は、上記実施形態に限定されるものではなく、例えば、車台１２の上に走行輪１３，１４を駆動するモータを設置したり、レール頭頂面２の錆を落とす研磨機を搭載したりするなど、本発明の趣旨を逸脱しない範囲で、各部の形状や構成を適宜変更して実施することも可能である。   In addition, this invention is not limited to the said embodiment, For example, the grinder which installs the motor which drives the driving wheels 13 and 14 on the chassis 12, and removes the rust of the rail top surface 2 is mounted. For example, the shape and configuration of each part can be changed as appropriate without departing from the spirit of the present invention.
