CONSTITUTION:Vertical pillars 1, 1 are vertically provided to a transferring path at its either side. Their upper parts are connected to each other by means of a horizontal rod 17 to form a gate type lifter. Next, a transverse bar 12 is penetrated through from one lower space of a belt conveyor 20 to belt width direction. Chain loop parts at both the ends are hung on suspension supporting material 7 on the vertical pillars 1, respectively. Then, handles 9 at both the ends are rotary-operated to elevate the suspension supporting material 7 by means of endless chains 5, lifting the conveyor 20 by means of the transverse bar 12. In this case, the declined members 12B, 12B of the transverse bar 12 are bent in parallel condition to declined rolls 21. The conveyor 20 is lifted while retaining its travelling shape. Inspection or repair work is done by utilizing the space formed at its lower part.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention lifts a long and wide belt conveyor provided for transferring ore, crushed stone, chemicals or the like to an isolated place when repairing or inspecting a transport path. For the device.

[0002]

2. Description of the Related Art Conventionally, for example, a long and wide belt conveyor is used for transporting ore or the like unloaded at a port or for crushing stones from a quarry, or chemicals.
Further, since a considerable load is applied to such a belt conveyor, an abnormality often occurs in the conveyor roll section and the driving section during use, and the conveyance is likely to be unsmooth. Therefore, regular maintenance work is required, and prompt repairs are required for unexpected accidents.

However, in the case of an unexpected repair work or periodic maintenance work in the case where an abnormality occurs in the conveyance path of the belt conveyor, conventionally, several workers cooperatively lift a part of the heavy belt conveyor, The actual situation is that the lifted belt is supported by the columns to keep the lifted state of the belt while the conveyor roll is repaired or inspected.

[0004]

However, the conventional work method of lifting the belt by the hand of the worker and supporting the lifted state by the support column as described above is not suitable for repairing an irregular sudden abnormality. Even if it is unavoidable, not only a lot of labor is required to regularly inspect and maintain the conveyor roll section and drive section, but also it is inefficient, and the work is harsh and uncertain in terms of safety. Remains.

The present invention provides a belt conveyor lifting device which is convenient not only for irregular repairs of a transport path but also for carrying out regular inspection and maintenance work of the transport path.

[0006]

According to the present invention, a belt-type lifting device for a belt conveyor can be arranged so as to straddle a conveyance path, and a simple belt-type lifter is inserted into the lower surface of the belt running on the front surface side so that the belt is lifted. The above problems have been solved by constructing a transverse bar for lifting. That is, the device for lifting a belt conveyor running on a long transport path according to the present invention includes a vertical support column provided with elevating means installed upright on both sides of the transport path, and a horizontal rod connecting the upper parts of both vertical support columns. , A suspension support member that is vertically moved by the elevating means on the inside of the vertical columns on both sides, and a transverse bar for lifting a belt conveyor that is detachably attached to the suspension support member, and the elevating means comprises The suspension supporting member is composed of a sprocket wheel provided above and below, an endless chain around which the sprocket wheel is wound, a worm for rotating the lower sprocket wheel, a worm wheel and a handle for rotating the worm. It is characterized in that it is fixed to the endless chain of the lifting means.

As a mechanism for rotating and driving the lower sprocket wheel in the elevating means, a wall wheel is provided on the shaft of the lower sprocket wheel, and a worm that meshes with the worm wheel is provided on the handle shaft and the worm is rotated by the handle. A means for operating the ratchet wheel on the shaft of the lower sprocket wheel and a means for engaging the anti-reverse ratchet on the ratchet wheel and turning the ratchet wheel by turning the handle can be applied. It is preferable that the worm and the worm wheel means have a reverse rotation preventing function and are safe and easy to operate. Also, other known technical means may be applied as appropriate. As a cross bar,
A horizontal intermediate member, and an inclined member pivotally attached to both sides of the intermediate member so as to stop at an inclined position along the inclination angle of the conveyor roll, or a metal rod shorter than the width dimension of the belt conveyor It is preferable to use a chain or a wire rope for hanging, and to have a structure in which the belt conveyor can be lifted in almost the same running state.

[0008]

For example, when regularly inspecting and maintaining a long conveyor path by means of a belt conveyor, first, vertical columns having elevating means are erected on both sides of the conveyor path, and the upper parts thereof are connected by horizontal rods to form a gate. Then, insert a transverse bar into the lower space on the surface side of the belt conveyor so that both ends of the transverse bar protrude approximately equally on both sides of the belt, and then both ends of the transverse bar are connected to the suspension supports of the vertical columns on both sides. Connect them with ropes, chains, etc., and then operate the elevating means of the vertical columns on both sides to raise the suspension support material and lift a part of the belt conveyor in a mountain shape to inspect and maintain the conveyor rolls. Create a working space.
