Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for assembling / disassembling a mobile crusher and a mobile crusher, for example, a mobile crusher configured to be movable by self-propelled or towed in a site of dismantling a building. Assembly method and mobile crusher.

[0002]

[Background Art] A mobile crusher that is carried into a quarry or a demolition site of a building, for example, has a crawler-type traveling unit so that it can be self-propelled within the site. Since it is not possible to drive on public roads, it is transported exclusively by trailers.

In transporting by trailer, a heavy and large mobile crusher is disassembled into several parts in order to pass over a bridge with a weight restriction or under an overpass with a low girder size. However, they may be transported by multiple trailers. In this case, conventionally, the working machine mounted on the mobile crusher is often removed from the base part of the mobile crusher and transported by a trailer different from the base part side. Such a working machine includes a hopper for inputting the crushed material, a feeder for supplying the crushed material input to the hopper to the crushing device,
And a crushing device therefor, and particularly, a crushed material supply unit is configured to include a hopper and a feeder.

[0004]

However, it is troublesome to remove and reassemble the hopper, the feeder, and the crushing device constituting the working machine for each transportation, and there is a problem that the labor and time are excessive. . Therefore, it is conceivable to remove only the crushing device, which has a remarkably large weight among the working machines, from the base part side, but the end of the crushed material supply part on the supply destination side is swallowed into the inlet of this crushing device. Therefore, it is necessary to remove the hopper and the feeder before removing the crushing device, and since the hopper is arranged on the feeder, it is necessary to remove the hopper before removing the feeder. For this reason, it is difficult to remove only the crushing device or to re-install it, and a means for solving the problem is desired.

There is also a demand to remove the crushing device and bring it to a factory or the like not only during transportation but also when the crushing device needs to be extensively repaired.
However, even in such a case, since it is necessary to remove the hopper and the feeder first, there is a problem that it takes time for the removing work and the re-assembling work.

An object of the present invention is to provide a method for assembling a mobile crusher, a method for disassembling the mobile crusher, and a mobile crusher, which can easily carry out the assembling work and the removing work of the crushing device. is there.

Therefore, even if the crushed material supply unit is already installed on the base unit, it is possible to reliably incorporate only the crushing device. Therefore, for example, when transporting a mobile crusher, only the crushing device needs to be separately transported, and only the crushing device needs to be installed on the base part side after transportation. Assembling work of the crushing device becomes easy because the assembling work becomes unnecessary. The same applies to the assembling work after the crushing device is repaired, and only the crushing device needs to be installed on the base side. The term "slide" as used herein means to slide or slide on an object, or to move the object in a slightly floating state, that is, to move the object horizontally.

And a crushing object supply section for supplying, the crushing apparatus is detachably mounted on the base section, and an end portion of the crushing object supplying section is provided at an input port of the crushing apparatus. It is swallowed, and on the side opposite to the crushable object supply part in the crushing device, a space part having a width dimension larger than the swallow size of the end part of the crushable object supply part to the charging port is provided. It is characterized by being formed.

In such a mobile crusher, a space having a width dimension larger than the swallowing dimension of the end of the crushable material supply section to the charging port is provided on the opposite side of the crushable material supply section. Since the part is formed, by sliding the crushing device using this space, it becomes possible to swallow the crushed material supply part into the crushing device and separate it from the crushing device without fail. Only the crushing device can be reliably and easily attached to and detached from the table part, which facilitates the assembling work and the removing work of the crusher.

A mobile crusher according to a fourth aspect of the present invention is the mobile crusher according to the third aspect of the present invention, in which the crushing device is provided on the side opposite to the object to be crushed supply section in the vertical direction from the lower end side. It is characterized in that a concave portion is provided up to the position, and the space portion faces the concave portion. According to such a mobile crusher, since the space portion is formed by the concave portion of the crushing device, there is no fear that the space portion causes the mobile crusher to become significantly large. In the crushing device, since the upper side of the concave portion is necessarily a convex portion, a mechanism for opening and closing the case of the crushing device may be provided using the convex portion.

A mobile crusher according to a fifth aspect of the present invention is the mobile crusher according to the third or fourth aspect, further comprising a work floor, and a portion of the work floor that closes the space portion is removed. It is possible to be outside. When the crushing device is fixed at the proper position, the space is closed by the work floor, and therefore the work floor needs to be removed from the space during assembly and disassembly. At this time, in the mobile crusher of the present invention, of the work floor, only the part that closes the space is removed, so there is no need to remove the entire work floor, and the installation / installation of the mobile crusher is not required. Outside work can be done quickly.

[Explanation of method for assembling / disassembling mobile crusher]
The mobile crusher 1 is transported along with the mobile crusher 1 by loading it on a trailer. At this time, the crusher 30 is used.
By setting the movable case 80 in the transportation posture, it is possible to clear the height restriction during transportation. However, if you have to pass over a bridge with weight restrictions during transportation, remove the crusher 30 with the largest weight, and
It may be transported by a trailer different from the base 2 side and the crusher 30 may be assembled to the base 2 at the destination. Hereinafter, a case where the crusher 30 and the base portion 2 side are separately transported will be described with reference to FIGS. 6 to 8.

In FIG. 6, a trailer T1 has a mobile crusher 1 (base 2 side) with a crusher 30 removed.
The crushers 30 that have been removed are placed on the trailer T2, and the crushers 30 are transported separately to a destination such as a quarry or a site for dismantling a building. Therefore, on the base part 2 side, the crushable material supply part 40 having the hopper 41 and the feeder 42 is provided.
Is already installed. Further, on the crusher 30 side, the second work floor 29 is attached in advance to the side surface portion 72 on the fixed case side. When transporting the crusher 30 alone, the height of the movable case 80 may be kept in the working posture in many cases because the height limit can be sufficiently cleared, but in some cases, it may be in the transporting posture. is there.

After arriving at the destination, the mobile crusher 1 is self-propelled and unloaded from the loading platform of the trailer T1. On the other hand, the crusher 30 is unloaded from the trailer T2 with a crane or the like not shown. That is, the wire rope 727 is hooked on the hook 726 (FIG. 7) provided on the side surface portion 72 of the crusher 30 on the fixed case side, and is hung down.

Then, as shown in FIG. 7, the crusher 30 hung by a crane is placed on the crusher mounting portion 211 of the mobile crusher 1. In this case, first, crusher 30
Is hung near the front of the crushing device mounting portion 211, that is, near the power unit 4, and is positioned in a state of being slightly floated from the crushing device mounting portion 211. At this time, in the first work floor 28 formed on the power unit 4, in order to avoid interference with the crusher 30, the closing plate 281 is rotated forward (see the chain double-dashed line in FIG. 5). deep.

Thereafter, as shown in FIG. 8, the crusher 3

Then, the crusher 30 is lowered and completely seated on the crushing device mounting portion 211, and fixed by bolting or the like. As a result, the crusher 30 is installed on the base portion 2 side, and a space portion 733 is formed in front of the crusher 30 with the power unit 4. Then, the closing plate 281 is rotated rearward to close the upper side of the space 733. As described above, the assembly of the mobile crusher 1 accompanied by the work of incorporating the crusher 30 is completed.

Furthermore, when returning after the crushing work is completed, the crusher 30 is removed from the mobile crusher 1 (on the side of the base unit 2), and each crusher 30 is loaded again into separate trailers T1 and T2 for transportation. Further, even when the crushing work is not completed, when only the crusher 30 is transported to the factory for repair or the like, the crusher 30 is removed from the mobile crusher 1 (base 2 side). As a procedure of the detaching work, the above-mentioned assembling work may be performed in reverse order.

Specifically, first, the fixed state of the crusher 30 and the crushing device mounting portion 211 in the state shown by the solid line in FIG. 8 is released, and the crusher 30 is slightly floated by the crane. After that, the crusher 30 is horizontally slid toward the side separated from the hopper 41 and the feeder 42 by utilizing the space 733, that is, toward the power unit 4, as shown by the chain double-dashed line. As a result, the input port 31A of the crusher 30 is separated from the ends of the hopper 41 and the feeder 42, and the ends are exposed. At this time, of course, the closing plate 281 is rotated forward.

Next, as shown in FIG. 7, the crusher 30
Is vertically lifted by a crane, completely removed from the base 2 side, loaded on a trailer T2 shown in FIG. 6, and transported. If the crushing work is completed and the mobile crusher 1 (base part 2 side) from which the crusher 30 has been removed is also transported and returned, the mobile crusher 1 is self-propelled and the trailer T1 is used. Just load it in and transport it. As described above, the dismantling of the mobile crusher 1 accompanied by the work of removing the crusher 30 is completed.

The crusher 30 may be installed in the mobile crusher 1 or removed from the mobile crusher 1 while the mobile crusher 1 is loaded on the trailer T1.

[Effects of the Embodiment] According to this embodiment, the following effects are obtained. (1) When incorporating the crusher 30 into the mobile crusher 1, the crusher 30 is slid toward the hopper 41 and the feeder 42, and the end portions of the hopper 41 and the feeder 42 are swallowed into the input port 31A of the crusher 30. Therefore, even if the hopper 41 and the feeder 42 are already installed in the base unit 2, the crusher 30
Only can be reliably incorporated. Therefore, at the time of transportation, since the crusher 30 may be transported separately from the side of the base portion 2, a troublesome work of incorporating the hopper 41 and the feeder 42 into the base portion 2 after transportation does not occur, and only the crusher 30 is transported. It can be easily incorporated into the base portion 2, and the assembling work can be facilitated. The same applies to the assembling work after the crusher 30 is repaired, and only the crusher 30 can be easily incorporated on the base 2 side.

(2) Then, in the removal work for removing the crusher 30 from the mobile crusher 1, the crusher 30 is slid to insert the inlet 31A into the hopper 41 and the feeder 42.
Since it is only necessary to separate the hopper 41 and the feeder 42 from the end portion of the base 2 and release the swallowed state, it is possible to remove only the crusher 30 without removing the hopper 41 and the feeder 42 from the base portion 2, and the removal work can be facilitated.

(3) In the mobile crusher 1, the front side of the crusher 30, that is, the hopper 41 and the feeder 4
2, a space portion 733 is formed on the side opposite to the space 2.
Since the width dimension W2 of 33 is larger than the swaging dimension W1 of the ends of the hopper 41 and the feeder 42 into the inlet 31A,
By sliding the crusher 30 using the space portion 733, the end portions of the hopper 41 and the feeder 42 can be swallowed into the crusher 30 without fail, and the end portions of the hopper 41 and the feeder 42 from the crusher 30 can be removed. Can be reliably separated. Therefore, even if the hopper 41 and the feeder 42 are installed in the base 2, it is possible to reliably and easily attach / detach only the crusher 30 to / from the base 2, and it is possible to easily perform the work of assembling / removing the crusher 30. .

(4) In the crusher 30, a concave portion 732 is provided on the side opposite to the hopper 41 and the feeder 42,
Since the space portion 733 faces the recessed portion 732, the space portion 733 can be formed by recessing the recessed portion 732. Therefore, unlike the case where the space 733 is formed by further separating the power unit 4 side from the crusher 30, there is no concern that the space 733 causes the mobile crusher 1 to be significantly enlarged.

(5) Further, by providing such a concave portion 732, a convex portion 731 protruding toward the power unit 4 side can be formed on the upper portion of the concave portion 732, and the convex portion 731 is utilized. A rotating mechanism 39 can be provided.

(6) The crusher 30 is the crushing device mounting portion 2
In the state of being fixed on 11, the space portion 733 is closed by the first work floor 28, but at the time of assembly and disassembly,
It is necessary to remove the first work floor 28 from the space 733. Therefore, in the present embodiment, the first work floor 2
Of the eight, the part that closes the space 733 is formed by the closing plate 281, and the closing plate 281 is rotatably provided. Therefore,
At the time of assembling and disassembling, since it suffices to rotate the closing plate 281 to avoid interference with the crusher 30, it is not necessary to remove the entire first work floor 28, and the assembling / removing work can be performed quickly.

(7) The mobile crusher 1 is also provided with a second work floor 29, but such a second work floor 29 is conventionally arranged close to the crusher 30 with almost no space. And is detachably attached to the base 2. Therefore, when the crusher 30 is installed or removed, it is necessary to remove the adjacent second work floor 29, which is troublesome. On the other hand, in the present embodiment, since the second work floor 29 is attached to the fixed case 70 of the crusher 30, the second work floor 29 can be attached and detached together with the crusher 30, and the second work floor 29 can be separately provided. The troublesome work of attaching and detaching can be eliminated, and the assembling / removing work can be further simplified.

(8) In addition, the crusher 30 of this embodiment
Has a configuration in which the height of the crusher 30 can be surely lowered by sinking the movable case 80 deeply into the fixed case 70. Therefore, even when the crusher 30 is transported without being removed from the base portion 2 side. If the movable case 80 is set in a lowered transportation posture, the height limit during transportation can be surely cleared. Further, even if the crusher 30 is upsized, the height limit can be surely cleared. Therefore, even if such a crusher 30 is installed, no problem occurs during transportation, and the crusher 30 can be upsized. Work can be done efficiently.

The present invention is not limited to the above-described embodiment, but includes other configurations and the like that can achieve the object of the present invention, and the following modifications and the like are also included in the present invention.
For example, in the above-described embodiment, the closing plate 281 that forms a part of the first work floor 28 is rotatably provided, and the closing plate 281 is rotated to remove it from the space 733. Such a blocking plate 281 may be detachably provided by bolting. In short, the closing plate 281 is
Any specific structure may be used as long as it can be removed from the space 733.

The width W of the space portion 733 in the above embodiment
2 was only slightly larger than the swallowing dimension W1 of the hopper 41 and the feeder 42, but the width dimension W2 of the space portion 733 was set so that the end portions of the hopper 41 and the feeder 42 were moved by sliding the crusher 30. The size may be such that it can be swallowed into the input port 31A, or the input port 31A can be separated from the ends of the hopper 41 and the feeder 42, and may be sufficiently larger than the swallow size W1.

In the above-described embodiment, the crusher 30 is slid in a state of being slightly floated from the crushing device mounting portion 211, but some kind of sliding mechanism or sliding mechanism is provided on the crushing device mounting portion 211 side. Alternatively, the crusher 30 may be slid while being mounted on such a mechanism.

In the above embodiment, the crusher 30 having the heaviest weight is removed from the mobile crusher 1 to clear the weight limitation during transportation. However, the present invention is not limited to this.
For example, the present invention can be applied even when it is necessary to remove only the hopper 41 and the feeder 42 for some reason. That is, when only the conventional hopper 41 and the feeder 42 are removed, the hopper 4 is taken into consideration in consideration of the swallowing portion with the crusher 30.
It was necessary to hoist the device 1 and the feeder 42 diagonally upward so as not to contact the input port 31A, and the hoisting operation was not easy. In addition, the hopper 41 and the feeder 4
Even if 2 is installed, hang it down diagonally,
I was swallowing it while hanging it down, and again, the lifting work was not easy.

Therefore, by applying the assembling / disassembling method of the present invention, the crusher 30 can be slid to release the swallowed state with the hopper 41 and the feeder 42.
The feeder 42 can be lifted vertically, and the lifting operation can be facilitated. In addition, the hopper 41 and the feeder 4
Even when hanging down 2, the crusher 30 may be slid in advance and retracted, the hopper 41 and the feeder 42 can be vertically lowered, and the hanging operation can be facilitated. Then, after the hanging work, the crusher 3
By sliding 0, the hopper 41 and the feeder 42
Just swallow the end of.

The movable case 80 of the above-described embodiment can be biased in a transportation posture in which it is deeply sunk with respect to the fixed case 70, so that the height limit during transportation can be cleared. However, the movable case 80 may be biased only in the work posture and the maintenance posture. Then, when it is necessary to remove only the crusher 30 from the base portion 2 for the purpose of clearing the height restriction during transportation, the assembly / disassembly method of the present invention may be applied.

Although the mobile crusher 1 of the above-described embodiment is a self-propelled type having the crawler type traveling unit 10, it is not limited to the crawler type and may be a wheel type or a self-propelled type. Not limited to this, it may be a tow type. In short, if it is movable, it is included in the mobile crusher of the present invention.

The crushing device of the present invention is not limited to the impact crusher 30 described in the above embodiment, but may be any crusher such as a jaw crusher, a shear crusher, a cone crusher, or a roll crusher.

In addition, the frame 20, crusher 30,
The configurations of the crushable object supply unit 40, the discharge belt conveyor 50, and the like can be arbitrarily changed within the range in which the object of the present invention can be achieved, and are not limited to the above-described embodiment.
