Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a hanger trolley for suspending and transporting a distribution hanger, and more particularly to a hanger trolley configured so that a trolley head does not rotate more than a certain angle.

[0002]

[Prior Art]

 Conventionally, a support frame is rotatably held at both ends of a load bar for suspending a distribution hanger, and a trolley head is attached to an upper end of the support frame, and the trolley head is used as a transport path space. There is a hanger trolley that is suspended from the rails installed in the trolley, and the trolley head is configured to be rotatable so that it can be used for any curved transport by means of a rail installed in the transport path space.

Since the hanger trolley has a front-back orientation because of the relationship with other devices for transporting the hanger trolley, a structure in which the trolley head can rotate more than necessary causes a worker to hang the trolley head on the rail. On the contrary, it becomes inconvenient. To prevent this, the trolley head has been designed to prevent it from rotating beyond a certain angle. In the conventional anti-rotation means, a part of the bearing portion at both ends of the load bar is machined into an elongated hole to form an engaging hole, and a spring pin is driven into the shaft portion of the frame to engage the spring pin. It was designed to be engaged with the dowel.

[0004]

[Problems to be solved by the device]

 However, in the conventional hanger trolley, a long hole-shaped engagement hole is formed in the bearing part, so the mechanical strength of the most important bearing part is reduced, and the partial machining of the load bar is performed. In addition, it is necessary to drive the spring pin at the time of assembly and assembling.In addition, the spring pin may be cut off due to misuse such as dropping the hanger trolley, and maintenance work for replacing the spring pin is required. Conventionally, the hanger trolley with a simple structure has drawbacks such as requiring a lot of labor and parts.

The object of the present invention is to solve the above-mentioned drawbacks of the conventional hanger trolley, to reduce the mechanical strength of the bearing part, which is an important part of the hanger trolley, and to provide various members constituting the hanger trolley. An object of the present invention is to provide a hanger trolley capable of reliably controlling the rotation angle of the trolley head with a simple configuration without requiring any machining or pin driving work.

[0006]

[Means for Solving the Problems]

 In the hanger trolley according to the present invention, a supporting frame is rotatably held at both ends of a load bar for suspending a distribution hanger, and a trolley head is attached to an upper end of the supporting frame. In a hanger trolley in which the head is suspended on a rail installed in the transport path space, the support frame is molded by die casting or the like, and a trolley head can be attached to the head attachment part formed at the upper end, A shaft mounting portion is formed at the lower end portion, the shaft portion is mounted on the shaft mounting portion, and the shaft portion is borne by the bearing portions formed at both end portions of the load bar. The butt head is integrally formed so that the trolley head does not rotate more than a certain angle when the engaging head contacts the load bar. .

[0007]

[Action]

 The support frame is formed by die casting or the like, the head mounting portion is formed on the upper portion, and the shaft mounting portion for mounting the shaft portion is formed on the lower portion. At this time, about two engaging projections are integrally formed at the lower end of the shaft mounting portion. The trolley head is attached to the head mounting portion on the upper part of the support frame, and the shaft portion is mounted on the lower shaft mounting portion. The hanger trolley is constructed by bearing the shafts of the pair of front and rear trolley bodies configured as described above by bearings at both ends of the load bar to connect the shafts with the load bar. The hanger trolley is suspended on rails installed in the transport path space, and a large number of logistics hangers are hung on the load bar and transported to the destination by a predetermined transport means. The support frame can rotate around the bearings at both ends of the load bar, so the trolley head attached to the upper end of this support frame can also rotate, allowing the rail to travel freely even if there is a curved portion. it can. An engaging protrusion is formed at the lower end of the shaft mounting portion of the support frame, and if the supporting frame tries to rotate more than necessary, the engaging protrusion abuts the load bar. When hanging the hanger trolley on the rail, the operator does not make a mistake in the front-back direction.

【Example】

 Embodiments of a hanger trolley according to the present invention will be described with reference to the drawings. FIG. 1 is a side view of a partially removed hanger trolley, FIG. 2 is a vertical sectional view of a trolley body, and FIG. 3 is a side view of a support frame. is there. In the figure, reference numeral 1 denotes a hanger trolley, which is constituted by connecting a pair of front and rear trolley bodies 10, 10 by a load bar 2 on which a large number of hangers such as clothes are suspended. The trolley body 10 is configured such that the trolley head 5 is attached to the upper end portion of the support frame 3 and the shaft portion 4 is provided to the lower end portion, and the shaft portion 4 is formed at both ends of the load bar 2. The bearing portion 21 is rotatably held by bearings.

The support frame 3 is formed by die casting and is formed into a substantially L-shape. The middle of the vertical portion is formed into a substantially H-shaped cross section, and the flat surface of the upper end portion is used as the head mounting portion 31, and the lower horizontal portion. The portion is the shaft mounting portion 32. At this time, the engaging projections 6 at about two places are integrally formed at the lower end of the shaft mounting portion 32. The trolley head 5, which is conventionally used and has rollers on the front and rear, is attached to the head attachment portion 31 of the support frame 3 so as to be swingable around the pivot 15, and the lower shaft attachment portion 32 is attached. A shaft member 4, which is a separate member, is attached to this so as to project downward. The hanger trolley 1 is constructed by bearing the shaft portions 4 of the pair of front and rear trolley bodies 10 thus configured by the bearing portions 21 at both ends of the load bar to connect the shaft portions 4 to each other by the load bar 2.

The hanger trolley 1 is suspended on a rail R installed in a transfer path space, a number of distribution hangers are hung on the load bar 2, and the hanger trolley 1 is transferred to a target place by a predetermined transfer means. The support frame 3 in which the shaft portion 4 is supported by the bearing portions 21 at both ends of the load bar can rotate, and accordingly, the trolley head 5 attached to the upper end portion of the support frame 3 can also rotate, and the rail R can be attached to the rail R. You can drive freely even if there are curved parts. However, when the hanger trolley 1 is hung on the rail R, the engaging projection 6 is projected at the lower end of the shaft mounting portion 32 of the support frame 3, and when the support frame is rotated more than necessary, the engagement projection 6 is generated. Since it comes into contact with the load bar 2, it does not rotate once, and the operator does not mistake the front-back direction of the hanger trolley 1.

[0011]

[Effect of the device]

 According to the hanger trolley of the present invention, the engaging projection is integrally formed at the lower end of the shaft mounting portion of the support frame, and when the support frame tries to rotate more than necessary, the engaging projection is attached to the load bar. Since it abuts, it does not rotate once, and the worker does not make a mistake in the front-back direction when hanging the hanger trolley on the rail. Since the support frame is molded by die casting, etc., and the engaging projections are also integrally molded, it is not necessary to hit the stopper pin as in the conventional case, and it is troublesome to cut or replace the stopper pin. Since it is not necessary and it is not necessary to cut the members constituting the hanger trolley, particularly the bearing portion of the load bar, the strength does not decrease.
