Description
Technical Field
The present invention relates to a connecting device for winding drums.
Background
Conventionally, belt conveyor apparatuses for conveying objects to be conveyed such as coal, ore, and sand have been widely used in the fields of mines, quarries, tunnel construction, and the like.
While such belt conveyor devices use long conveyor belts of, for example, 100m to 500 m.
On the other hand, since the splicing operation of the conveyor belt requires a lot of effort and time, it is desirable to reduce the splice sites at the site of use.
Therefore, the conveyor belt is manufactured as long as possible in a manufacturing factory or the like, wound around a winding drum, and then transported from the manufacturing factory or the like to a use site, whereby the amount of work required for splicing at the use site is reduced.
The winding drum includes, for example, a hollow winding core portion penetrating through the winding shaft insertion hole, and a pair of flange portions provided at both axial end portions of the winding core portion.
Then, the winding shaft inserted through the winding shaft insertion hole is rotated at the manufacturing factory, and the rotational force of the winding shaft is transmitted to the winding core portion, whereby the conveyor belt is wound around the winding core portion between the pair of flange portions.
In this case, when a long conveyor belt having a relatively narrow width is wound around the winding drum, the outer diameter (height) of the winding drum around which the conveyor belt is wound is larger than the width thereof, and the winding drum is liable to fall over.
That is, if the ratio of the outer diameter (or height)/width of the winding drum around which the conveyor belt is wound (hereinafter, this ratio will be simply referred to as "aspect ratio") is 3.3 or less, the winding drum is not liable to fall over and is suitable for transportation, but if the aspect ratio exceeds 3.3, the winding drum is liable to fall over and is therefore unsuitable for transportation.
For this reason, a method of winding a long conveyor belt around two winding drums has been conventionally disclosed (see patent document 1).
In this conventional winding method, one half of the conveyor belt is wound around one winding drum in a manufacturing factory, the other half of the conveyor belt is reversely wound around the other winding drum, and then flange portions of the two winding drums are positioned on the same plane to connect the two winding drums in an aligned manner, thereby reducing the aspect ratio and ensuring stability during handling.

Problems to be solved by the invention
However, with this method, the end of a conveyor belt must be withdrawn for use in the field.
Therefore, an operation of winding the conveyor belt wound on one winding drum onto the other winding drum is required, so that there are drawbacks as follows: the use site is time-consuming and labor-consuming, and even if the winding drum is disconnected, the conveyor belt cannot be easily used.
The present invention has been made in view of the above circumstances, and an object thereof is to provide a connection device for a winding drum that can ensure stability during transportation and can be easily used even in a use site.
Technical means for solving the problems
In order to achieve the above object, one embodiment of the present invention is a connection device for connecting a plurality of winding drums for a conveyor belt, the winding drum being provided with a hollow winding core portion penetrating a winding shaft insertion hole and a pair of flange portions provided at both axial ends of the winding core portion, wherein the connection device is provided with a movement preventing member which is inserted into the winding shaft insertion hole of the plurality of winding drums aligned with the axial center of the winding core portion to prevent the winding drums arranged at both ends from moving in the axial center direction.
Effects of the invention
According to one embodiment of the present invention, since the plurality of winding drums are held in a state in which the axes of the winding cores are aligned by the connection device of the winding drums, even if the aspect ratio of each of the plurality of winding drums exceeds 3.3, the aspect ratio can be controlled to 3.3 or less as a whole.
Therefore, stability during transportation can be ensured, and the winding drum can be easily used even at the site of use by removing the coupling device.

Hereinafter, embodiments of the present invention will be described with reference to fig. 1 to 6.
The winding drum 10 shown in fig. 1 and 2 is used for winding a long-sized conveyor belt. For example, a manufacturing factory winds a conveyor belt around a winding drum 10, and carries the winding drum 10 around which the conveyor belt is wound to a use site, and uses the winding drum 10 at the use site.
The winding drum connecting device 30 of the present embodiment connects a plurality of such winding drums 10 in an aligned manner.
First, the winding drum 10 of the conveyor belt will be described.
The winding drum 10 is made of metal, and as shown in fig. 2, includes a winding core 12 and a pair of flange portions 14.
The winding core 12 is a hollow cylindrical member having a winding shaft insertion hole 1202 having a circular cross section, and when winding the conveyor belt, the conveyor belt is wound around the outer periphery of the winding core 12.
Both ends of the winding core 12 are attached to a center portion of a cross plate 18 of a flange portion 14 described later by welding or bolts (not shown).
The pair of flange portions 14 are provided at both axial end portions of the winding core portion 12, and are portions for maintaining the shape of the conveyor belt wound around the winding core portion 12.
The pair of flange portions 14 includes an outer ring plate 16, a cross plate 18, and a receiving plate 20. In the following description, the axial direction of the winding core 12 is denoted by reference numeral 12A.
The outer ring plates 16 are plate-like members provided on both sides of the axial direction 12A of the winding core 12 and extending annularly along the outer peripheral portion of the conveyor belt wound around the winding core 12, and are formed in such a manner that the outer peripheral ends 1602 thereof are positioned radially outside the conveyor belt wound around the winding core 12.
At a position where the cross plate 18 is not attached to the outer peripheral end 1602 side of the outer ring plate 16, 8 screw holes 1604 for attaching a coupling member 40 described later by bolts are formed. The screw holes 1604 are formed in pairs in the circumferential direction of the outer ring plate 16 and are provided at 4 positions spaced apart equally in the circumferential direction of the outer ring plate 16.
The cross plate 18 is a plate member provided on both outer sides of the axial direction 12A of the outer ring plate 16 and extending in the vertical and horizontal directions orthogonal to each other, and a tip portion of the plate member extending in the vertical and horizontal directions is attached to the outer ring plate 16 by welding or bolts (not shown).
A winding shaft insertion hole 1202 is formed in the center of the cross plate 18.
The receiving plate 20 is an annular plate provided on the other two outer sides in the axial direction 12A of the winding core 12, and has a winding shaft insertion hole 1202 formed in the center.
The receiving plate 20 is mounted to the cross plate 18 of the flange portion 14 by welding or bolts (not shown).
8 screw holes 2002 for attaching an abutment member 36 to be described later by bolts are formed on the radially outer side of the winding shaft insertion hole 1202 of the receiving plate 20 at predetermined intervals in the circumferential direction. In the present embodiment, 8 screw holes 2002 are formed, but the number of screw holes 2002 is arbitrary.
When the conveyor belt is wound using such a winding drum 10, as shown by a broken line in fig. 2 (a), a winding shaft 22 made of metal and having a circular cross section is inserted into the winding shaft insertion hole 1202.
The winding shaft 22 is provided with a flange (not shown) that is integrally rotatably coupled to the receiving plate 20 of the winding drum 10.
Then, the inserted winding shaft 22 is rotated, and the rotational force of the winding shaft 22 is transmitted to the flange portions 14, whereby the winding core portion 12 is rotated, and the conveyor belt is wound around the winding core portion 12 between the pair of flange portions 14.
Next, the connection device 30 of the winding drum according to the present embodiment will be described.
The winding drum connecting device 30 is used for connecting a plurality of winding drums 10 arranged with the axes of the winding cores 12 aligned. In the present embodiment, the case where two winding drums 10 are connected is described as an example as shown in fig. 1, but the number of winding drums 10 to be connected may be 3 or more.
The coupling device 30 of the winding drum comprises a movement preventing member 32, a buffer 38, a coupling member 40 and a suspension clamp 42.
The movement preventing member 32 is made of metal, and as shown in fig. 3, includes a shaft member 34 and a pair of abutment members 36, and connects the plurality of winding drums 10 arranged so that the axes of the winding cores 12 are aligned.
The shaft member 34 is a rod-shaped member having a circular cross section, and is formed to have a length protruding from the side surface of the flange portion 14 of the winding drum 10 arranged at both ends by being inserted into the winding shaft insertion holes 1202 of the plurality of winding drums 10 arranged with the axes of the winding cores 12 aligned.
In the present embodiment, since two winding drums 10 are connected, the two winding drums 10 are arranged at both ends.
The pair of contact members 36 are members provided at both ends of the shaft member 34, and contact the receiving plates 20 forming the side surfaces of the flange portions 14 of the winding drums 10 arranged at both ends, to prevent the plurality of winding drums 10 arranged at both ends from moving in a direction away from each other in the longitudinal direction of the shaft member 34.
The abutment member 36 includes an annular plate 3604 formed with a shaft member insertion hole 3602 through which the shaft member 34 is inserted, and a boss portion 3606 provided on one face of the annular plate 3604.
At the outer side of the annular plate 3604 in the radial direction than the boss portion 3606, there are formed 8 bolt insertion holes 3608 through which bolts are inserted when the abutment member 36 is detachably attached to the receiving plate 20.
The bolt insertion holes 3608 are provided at predetermined intervals in the circumferential direction so as to correspond to the screw holes 2002 of the receiving plate 20, and are formed as long holes or holes slightly larger than the shaft portions of the bolts so as to be finely adjustable at the time of installation.
A screw hole 3610 extending radially from the outer peripheral surface toward the shaft member insertion hole 3602 is formed in the boss portion 3606.
When the pair of abutment members 36 are attached to the shaft member 34, the boss portions 3606 are disposed on both end portions sides of the shaft member 34, and a stopper screw (set screw) S or a bolt is screwed into the screw hole 3610, whereby the shaft member 34 is pressed in a direction orthogonal to the axial direction to fix the abutment members 36. That is, a pair of abutment members 36 are detachably attached to both ends of the shaft member 34.
The buffer 38 is provided between the facing flange portions 14 of the winding drums 10 adjacent to each other, suppresses movement of the winding drums 10 adjacent to each other in a direction approaching each other in the longitudinal direction of the shaft member 34, and is detachably attached to the shaft member 34 of the movement preventing member 32.
The cushion material 38 of the present embodiment is formed in a rectangular plate shape using rubber as an elastic material, and has elasticity.
As shown in fig. 4, the cushion 38 includes a cushion body 3804 having a thickness corresponding to a dimension between the facing flanges 14 of the winding drums 10 adjacent to each other, mountable on the shaft member 34, and formed with a through hole 3802, and a cutout 3806 formed over the entire length of the cushion body 3804 in the thickness direction, enabling the through hole 3802 to be opened.
The coupling member 40 couples the side surfaces of the flange portions 14 of the winding drums 10 arranged at both ends to each other on the outer side in the radial direction of the conveyor belt wound around the winding core 12, prevents the winding drums 10 arranged at both ends from moving away from each other in the longitudinal direction of the shaft member 34, and is detachably attached to the outer ring plate 16.
The connecting member 40 is made of metal, and as shown in fig. 5, includes a rectangular elongated plate member 4002, and a pair of rectangular side plate members 4004 provided at both longitudinal ends of the plate member 4002 and extending perpendicularly to the plate member 4002.
Bolt insertion holes 4006 through which bolts are inserted when the coupling member 40 is detachably attached to the outer ring plate 16 are formed in pairs in the pair of side plate members 4004.
The suspension jigs 42 are provided on the side surfaces of the flange portions 14 of the winding drums 10 arranged at both ends, and perform a lifting operation when moving the plurality of winding drums 10 coupled by the movement preventing members 32 (the shaft member 34 and the pair of abutment members 36).
The suspension clamp 42 is made of metal, and includes a rectangular mounting plate portion 4202 and a curved plate portion 4204 mounted on an upper portion of the mounting plate portion 4202, as shown in fig. 6.
The mounting plate portion 4202 is formed to have a smaller width than the plate member of the cross plate 18.
The curved plate portion 4204 extends in the horizontal direction from the upper end of the mounting plate portion 4202, and then is curved downward from the front end thereof.
As shown in fig. 1, the suspension clamp 42 is attached to the front end side of the plate member of the flange portion 14 extending upward of the cross plate 18 by bolts (not shown) or welding.
When lifting the plurality of winding drums 10, a lifting member such as a rope or a chain is placed in a space surrounded by the mounting plate portion 4202 and the curved plate portion 4204, and pulled upward, thereby lifting the plurality of winding drums upward, and thereby being movable to a desired position.
In the present embodiment, as shown in fig. 1, the flange portions 14 are attached not only to the flange portions 14 located on the outer sides of the winding drums 10 arranged at both ends, but also to the flange portions 14 at both ends of all the winding drums (both winding drums 10). This makes it possible to use the winding drum 10 even when it is moved before or after the connection.
Next, a method of connecting a plurality of winding drums 10 using the connection device 30 of the winding drum according to the present embodiment will be described.
An example in which two winding drums 10 around which a conveyor belt is wound are coupled and transported from a manufacturing site to a use site by a vehicle is shown below.
First, when the winding drums 10 are arranged on the floor, the winding drums 10 are lifted and moved by the suspension jigs 42 attached to the respective winding drums 10, and the winding cores 12 are aligned with the axes thereof.
Next, the movement preventing member 32 is mounted on the aligned two winding drums 10.
Specifically, the shaft members 34 of the movement preventing members 32 are inserted into the winding shaft insertion holes 1202 of the two winding drums 10 arranged so that both ends of the shaft members 34 protrude from the side surfaces of the flange portions 14 of the winding drums 10 arranged at both ends, respectively.
Next, the buffer 38 is mounted between the facing flange portions 14 of the winding drums 10 adjacent to each other.
Specifically, the cutout 3806 of the cushion 38 formed of rubber is enlarged, and the shaft member 34 is pressed into the enlarged cutout 3806, and is disposed at a position where the shaft member 34 is fitted into the through hole 3802.
Next, the winding drums 10 adjacent to each other are pressed in the direction approaching each other, and both end portions of the protruding shaft member 34 are inserted into the shaft member insertion holes 3602 of the pair of abutment members 36, respectively, to be disposed.
Then, the pair of abutment members 36 are mounted on the receiving plates 20 of the pair of flange portions 14, respectively.
Specifically, the bolt insertion hole 3608 of the abutment member 36 is aligned with the screw hole 2002 of the receiving plate 20, and the bolt inserted through the bolt insertion hole 3608 is screwed into the screw hole 2002, whereby the abutment member 36 of the movement preventing member 32 is mounted on the receiving plate 20 of the flange portion 14.
Next, the winding drums 10 adjacent to each other are pressed in the direction approaching each other, and the pair of abutment members 36 are mounted on the shaft member 34 by the stopper screw S.
The abutment members 36 of the movement preventing member 32 may be attached to the receiving plate 20 of the flange portion 14, and after the pair of abutment members 36 are attached to the shaft member 34 by the stopper screw S, the buffer member 36 may be attached to the shaft member 34.
Further, since the abutment members 36 prevent the winding drums 10 arranged at both ends from moving in the direction away from each other, the abutment members 36 may not be mounted on the receiving plate 20.
However, when the abutment member 36 is mounted on the receiving plate 20, the winding drums 10 arranged at both ends are rotatably coupled integrally with the shaft member 34, so that the winding drums 10 at both ends are prevented from idling on the shaft member 34, and thus it is advantageous to easily operate the plurality of winding drums 10 coupled by the coupling device 30.
Next, the side surfaces of the flange portions 14 of the winding drum 10 arranged at both ends are connected by the connecting member 40.
Specifically, the connecting member 40 is arranged outside the outer ring plate 16 of the winding drum 10, the bolt insertion holes 4006 formed in the side plate members 4004 of the connecting member 40 are aligned with the screw holes 1604 formed in the outer ring plate 16, and the bolts inserted through the bolt insertion holes 4006 are screwed into the screw holes 1604, whereby the connecting member 40 is mounted on the outer ring plate 16.
After the two winding drums 10 are connected in this manner, the connected two winding drums 10 are mounted on the transport vehicle by the suspension jigs 42 attached to the flange portions 14 of the winding drums 10 arranged at both ends.
Then, when the transport vehicle arrives at the use site, the two connected winding drums 10 are detached from the transport vehicle by the suspension jigs 42 as in the loading.
The coupling means 30 of the winding drum 10 are detached from the two winding drums 10 detached from the transport vehicle. The disassembly method is performed in the reverse step to the assembly. That is, the coupling member 40, the movement preventing member 32, and the damper 38 are detached in order.
The cushioning material 38 of the present embodiment is made of rubber and includes one member, but may be made of other materials such as wood, synthetic resin, metal, and the like, and includes two members.
The cushioning member 48 shown in fig. 7 is made of wood, has a length corresponding to the diameter of the flange portion 14, and includes two elongated split bodies 50. The divided bodies 50 are formed with semicircular notch portions 5002 at the central portion of one side face in the longitudinal direction, and when the two faces of the two divided bodies 50 where the notch portions 5002 are formed are aligned with each other, circular opening portions are formed by the notch portions 5002.
The two divided bodies 50 are disposed so as to sandwich the shaft member 34 between the facing flange portions 14 of the two winding drums 10 adjacent to each other, and both ends of the two divided bodies 50 in the longitudinal direction are fastened by a belt or the like, whereby the damper 48 is attached to the shaft member 34.
As described above, by the winding drum connecting device 30 according to the present embodiment, since the plurality of winding drums 10 are held in a state in which the axes of the winding cores 12 are aligned, even if the aspect ratio of each of the plurality of winding drums 10 exceeds 3.3, the aspect ratio can be controlled to 3.3 or less as a whole.
Therefore, stability during transportation can be ensured, and the winding drum 10 on which the long-sized conveyor belt is wound can be easily used even at the site of use by removing the coupling device 30.
The abutment member 36 may not be attached to the receiving plate 20 of the flange portion 14, but if the abutment member 36 is detachably attached to the receiving plate 20, it is advantageous to operate the plurality of winding drums 10 in a more stable state.
The buffer 38 may be omitted, and the plurality of winding drums 10 may be inserted through the shaft member 34 in a state of being in contact with each other, and the plurality of winding drums 10 may be prevented from moving by the pair of contact members 36.
However, if the damper 38 is provided as in the present embodiment, it is advantageous to prevent damage to the adjacent winding drums 10 due to vibration of the vehicle or the like during transportation.
Further, if the buffer 38 is configured to use the shaft member 34 and is detachably mounted on the shaft member 34, it is advantageous to easily perform the mounting and dismounting of the buffer 38.
At this time, an elastic material may be used as the cushion material 38, the cushion material 38 may be easily formed by the cushion body 3804 and the slit 3806, the cushion body 3804 may be attached to the shaft member 34, and the through hole 3802 may be formed, and the slit 3806 may be formed over the entire length of the cushion body 3804 in the axial direction, enabling the through hole 3802 to be opened.
Further, by further providing the coupling member 40 for coupling the side surfaces of the flange portions 14 of the winding drums 10 arranged at both ends to each other on the outer side in the radial direction of the conveyor belt wound around the winding core 12, the winding drums 10 arranged at both ends can be coupled to each other on the outer side in the radial direction of the winding drum 10, and thus, the plurality of winding drums 10 can be easily handled, and transportation in a more stable state can be facilitated.
Further, since the coupling member 40 is configured to be detachably mounted on the outer ring plate 16 provided on the flange portion 14, it is advantageous to easily couple the side surfaces of the flange portions 14 of the winding drum 10 arranged at both ends.
Further, since the suspension jigs 42 for performing the lifting operation when moving the plurality of winding drums 10 connected by the movement preventing members 32 (the shaft member 34 and the pair of abutment members 36) are further provided on the side surfaces of the flange portions 14 of the winding drums 10 arranged at both ends, it is advantageous to easily move the connected plurality of winding drums 10.
