Description
【０００１】[0001]
本考案はクレ−ンにおけるドラムブレ−キ機構に関するものであり、特に左／ 右ドラムブレ−キの調整を不要とするブレ−キ機構に関するものである。 The present invention relates to a drum brake mechanism in a crane, and more particularly to a brake mechanism that does not require adjustment of the left / right drum brakes.
【０００２】[0002]
従来のドラムブレ−キ機構は、図１に示すように主として輪状のブレ−キバン ド２、その内周に施されたブレ−キライニング３、連結軸４、連結ロッド５、レ バ−６及び調整ボルト１とから構成されている。 As shown in FIG. 1, the conventional drum brake mechanism is mainly a ring-shaped brake band 2, a brake lining 3 provided on the inner periphery thereof, a connecting shaft 4, a connecting rod 5, a lever 6 and an adjusting member. It is composed of a bolt 1.
【０００３】 このドラムブレ−キ機構は、連結軸４の回転で連結ロッド５が移動し、ブレ− キバンド２でブレ−キドラムを締めて、ブレ−キをきかせるものである。In this drum brake mechanism, the connecting rod 5 is moved by the rotation of the connecting shaft 4, and the brake drum is tightened by the brake band 2 to make the brake effective.
【０００４】[0004]
上記ドラムブレ−キ機構の場合、ブレ−キバンド２とブレ−キドラムとの間隔 が、左／右ブレ−キで差が生じた時には、片側のブレ−キだけしかきかなくなり 、ブレ−キライニング３が摩耗しブレ−キが甘くなり非常に危険である。この場 合、左／右ブレ−キのバランス調整をする必要があるが、この調整は現場で調整 ボルトにて行なうが、ブレ−キの調整は、ブレ−キドラムとブレ−キバンドの間 隔を調整ボルトで均一に調整し、左／右ブレ−キのバランス調整を行うため相当 に時間のかかるものである。 本考案は、従来技術の上記問題点に鑑み、左／右ブレ−キを調整する手間を省 き、作業効率を向上させることを目的とする。 In the case of the above-mentioned drum brake mechanism, when there is a difference in the distance between the brake band 2 and the brake drum between the left and right brakes, only one side of the brake can be used, and the brake lining 3 is used. It is very dangerous because it becomes worn and the brake becomes loose. In this case, it is necessary to adjust the balance between the left and right brakes, but this adjustment is done on-site with the adjustment bolts, but the adjustment of the brake is done by adjusting the distance between the brake drum and the brake band. It takes a considerable amount of time to adjust the balance between the left and right brakes by adjusting the adjustment bolts evenly. SUMMARY OF THE INVENTION The present invention has been made in view of the above problems of the prior art, and an object of the present invention is to save the trouble of adjusting the left / right brake and improve the work efficiency.
【０００５】[0005]
内周にブレ−キライニングが施された輪状のブレ−キバンドを連結軸の回転力 を利用してレバ−を回動させることによりブレ−キバンドに引張力を与え、ブレ −キバンドとブレ−キドラムの間に摩擦力を発生させてブレ−キドラムを制動す るドラムブレ−キ機構において、１つのブレ−キドラムに対し左右２つの前記ブ レ−キバンドを巻きつけ、各々の前記レバ−にロッドを介してピン結合され、前 記連結軸にも連結ロッドを介してピン結合されたイコライザビ−ムを設けた。 A ring-shaped brake band with a brake lining on the inner circumference is used to rotate the lever by using the rotational force of the connecting shaft to give a tensile force to the brake band, and the brake band and the brake drum. In a drum brake mechanism that generates a frictional force between the brake drums to brake the brake drums, the two brake bands on the left and right are wound around one brake drum, and a rod is provided around each lever. An equalizer beam, which is pin-connected by means of a connecting rod, is also provided on the connecting shaft.
【０００６】[0006]
連結軸の回転により連結ロッドが移動し、イコライザビ−ムにロッドを介して ピン結合された左右のレバ−が回動することにより左右のブレ−キバンドに均等 の引張力を与え、ブレ−キバンドとブレ−キドラムの間に摩擦力を発生させてブ レ−キドラムを制動する。 The rotation of the connecting shaft causes the connecting rod to move, and the left and right levers pin-connected to the equalizer beam via the rod rotate to impart an equal tensile force to the left and right brake bands, thereby providing the brake band. The brake drum is braked by generating a frictional force between the brake drum and the brake drum.
【０００７】[0007]
本考案の実施例を図２に基づいて説明する。１２はブレ−キバンド、１３はブ レ−キライニング、１４は連結軸、１５は連結ロッド、１６はレバ−、１７はロ ッド、１８はイコライザビ−ムである。ブレ−キバンド１２、ブレ−キライニン グ１３及びレバ−１６の構成は従来のドラムブレ−キ機構で使用されているもの と同様である。従って、連結軸１４からレバ−１６までの連結機構について説明 する。 An embodiment of the present invention will be described with reference to FIG. Reference numeral 12 is a break band, 13 is a break lining, 14 is a connecting shaft, 15 is a connecting rod, 16 is a lever, 17 is a rod, and 18 is an equalizer beam. The structures of the break band 12, the break lining 13 and the lever 16 are the same as those used in the conventional drum break mechanism. Therefore, the connecting mechanism from the connecting shaft 14 to the lever 16 will be described.
【０００８】 まず、本実施例に係るドラムブレ−キ機構は、１つのブレ−キドラムに対し左 右２つのブレ−キバンド１２を巻きつけてあるので、ブレ−キバンド１２に設け られているレバ−１６も２つ存在する。レバ−１６は回動可能に取付けられてお り、レバ−１６を回動することによりブレ−キバンド１２に引張力を与え、ブレ −キバンド１２の内周に施されたブレ−キライニング１３とブレ−キドラムの間 に摩擦力を発生させることによりブレ−キドラムを制動する機構は従来技術と同 様である。First, in the drum brake mechanism according to the present embodiment, two brake bands 12 on the left and right are wound around one brake drum, and therefore the lever 16 provided on the brake band 12 is provided. There are also two. The lever 16 is rotatably attached, and when the lever 16 is rotated, a tensile force is applied to the brake band 12 and the brake lining 13 provided on the inner circumference of the brake band 12 is provided. The mechanism for braking the brake drum by generating a frictional force between the brake drums is the same as in the prior art.
【０００９】 イコライザビ−ム１８は、連結軸１４の軸方向に平行に設けられた細長のビ− ムであり、左右のレバ−１６にロッド１７を介してピン結合され、かつ、連結軸 １４にも連結ロッド１５を介してピン結合されている。The equalizer beam 18 is an elongated beam that is provided in parallel with the axial direction of the connecting shaft 14, and is pin-connected to the left and right levers 16 via a rod 17, and is also connected to the connecting shaft 14. Also, it is pin-connected via the connecting rod 15.
【００１０】[0010]
連結軸と左右のレバ−をイコライザビ−ムで連結したので、常に左右のブレ− キの利きが均等になるため、ブレ−キの調整が不要となる。 また、左右のブレ−キライニングの偏摩耗がなくなるためブレ−キライニング の寿命がのびる。 Since the connecting shaft and the left and right levers are connected by the equalizer beam, the left and right brakes are always equal in efficiency, so that adjustment of the brakes is unnecessary. In addition, the uneven wear of the left and right brake linings is eliminated, extending the life of the brake linings.
