昇降機に取付けている。 This type of elevator has wheels that can be attached to and removed from the guide grooves of the Annai rails installed in parallel, and can be raised and lowered by inserting the wheels into the guide grooves. It is designed to go up and down. Therefore, if a wheel or axle is damaged, there is a risk that the elevator will separate from the guide rail and fall. Conventionally, in order to prevent separation due to such damage, a locking piece whose tip can be positioned within the guide groove is attached to the elevator.
しかしながら、この係止片は案内溝内に挿入さ
れる車輪と無関係に取付取外しできるため、昇降
機を案内軌条に装着する際係止片の取付けを忘れ
る可能性があり極めて危険であつた。 However, since this locking piece can be attached and removed independently of the wheels inserted into the guide groove, it is extremely dangerous to forget to attach the locking piece when attaching the elevator to the guide rail.
この考案はこのような事情に鑑みて創案された
もので、その目的は係止片の取付け忘れが解消さ

ことができないようにしたものである。 In the safety device according to this invention, the axle is attached to the guide rail so that it can move forward and backward, and the axle is fixed by a knock pin with the wheel advanced into the guide groove. The locking piece is pivoted so that it can be inserted into and removed from the guide groove, and the locking piece has a shape that blocks at least a portion of a dowel pin insertion hole drilled in the axle support part when the locking piece is installed and removed with its tip protruding from the guide groove. The lock pin for fixing the axle cannot be inserted until after the locking piece is fixed with its tip located in the guide groove.
以下この考案を図示する一実施例に基づいて説

対の車輪２を上下に計四つ有し、溝形鋼からなる
案内軌条３を案内とし、ピンラツク４およびスプ
ロケツト５により昇降する。 This invention will be explained below based on an illustrated embodiment. As shown in FIG. 1, the elevator 1 has a pair of wheels 2 on the left and right, and a total of four upper and lower wheels, is guided by a guide rail 3 made of channel steel, and is raised and lowered by a pin rack 4 and a sprocket 5.
案内軌条３はその案内溝３Ａが互いに外方へ向
くように並列して立設され、車輪２はこの案内溝
３Ａ内に位置するよう昇降機の車軸支持部６から
内方に向けて取付けられている。 The guide rails 3 are erected in parallel so that their guide grooves 3A face outward, and the wheels 2 are mounted inward from the axle support 6 of the elevator so as to be located within the guide grooves 3A. There is.

間にばね材８を取付けることにより車軸７は案内
溝３Ａと反対方向に付勢されている。すなわち、
昇降機１を案内軌条３に装着する前においては、
このばね材８により車輪２は車軸支持部６側に引

Ａに挿入したならノツクピン９を車軸７を貫通し
て車軸支持部６に取付け、これにより車軸７を車
軸支持部６に固定する。１０はノツクピン９の脱
落を防止するリングストツパである。 As shown in FIGS. 2 and 3, the wheel 2 is rotatably attached to the tip of an axle 7, and the axle 7 is attached to the guide groove 3A by penetrating the axle support 6 so that it can move forward and backward toward the guide groove 3A. . The rear end of the axle 7 protrudes from the axle support part 6, and a locking collar 7 is provided at the rearmost end.
A is formed, and this locking collar 7A and the axle support part 6
By installing a spring member 8 between them, the axle 7 is biased in the opposite direction to the guide groove 3A. That is,
Before attaching the elevator 1 to the guide rail 3,
The spring material 8 draws the wheel 2 toward the axle support 6, so that the elevator 1 can be easily attached to the guide rail 3. Wheel 2 into guide groove 3
Once inserted into A, the dowel pin 9 is passed through the axle 7 and attached to the axle support 6, thereby fixing the axle 7 to the axle support 6. 10 is a ring stopper that prevents the dowel pin 9 from falling off.

が設けられ、係止片１１を取外しできないように
してある。 A locking piece 11 is attached to the upper surface of the axle support portion 6 configured in this manner. The locking piece 11 is rotatably attached to the axle support portion 6 at its base portion 11B with a bolt 12 so that the tip portion 11A can move in and out of the guide groove 3A. This base 11
B is shaped so that at least a portion of the dowel pin insertion hole formed in the axle support portion 6 is closed when the tip portion 11A comes out from the guide groove 3A. At the top of the bolt 12 is a bolt retaining piece 13.
is provided so that the locking piece 11 cannot be removed.

クピン９の脱落が防止される。 In such a configuration, the elevator 1 is connected to the guide rail 3.
When the axle 7 is mounted on the axle 7, the base 11B of the locking piece 11 partially blocks the dowel pin insertion hole, making it impossible to insert the dowel pin 9 and fix the axle 7. Therefore, after rotating the locking piece 11 so that the tip 11A is located in the guide groove 3A and fixing it with the bolt 14, the axle 2 is inserted into the guide groove 3A and the knock pin 9 is inserted to fix it. . A ring stopper 10 is attached to the knock pin 9 in advance, and the ring stopper 10 is rotated to engage the tip of the knock pin. This prevents the knock pin 9 from falling off.

全に防ぐことができ昇降機の安全性が極めて向上
することになる。 As mentioned above, the safety device of this invention has a locking piece mounted on the top surface of the axle support part to which the axle, which is movable forward and backward with respect to the guide rail, is fixed by a dowel pin, so that the tip can move in and out of the guide groove. At the same time, a portion of the locking piece blocks the dowel pin insertion hole with the tip protruding from the guide groove, so the axle must be fixed after the wheel is inserted until the locking piece is completely installed. This completely prevents the user from forgetting to attach the locking piece, thereby greatly improving the safety of the elevator.
