Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a slope indicator that can efficiently operate a bucket so that a slope becomes a predetermined slope without being an expert or an assistant.
[0002]
[Prior art]
In the civil engineering work, the work for finishing the slope to a predetermined slope is performed using an excavator or the like. In the present application, the excavator is not an excavator loader, but means an excavator attached to a cargo handling end of a crane and performing a slope finishing operation with the bucket.
[0003]
Slope finishing work using an excavator is performed by positioning the vehicle body at a position away from the slope to be finished, maintaining the bucket at a predetermined angle, and operating the bucket in the excavation direction while breaking the slope. Do that. This is because, when the vehicle body is located near the actual finishing position like an excavator loader, the slope of the slope is difficult to grasp and it is difficult to finish the slope accurately.
[0004]
In this operation, a bucket dedicated to a slope having no claw in the excavation part is mainly used, but a standard excavation, loading and cutting bucket having a claw in the excavation part may be used.
[0005]
In order to level the slope to a predetermined angle, conventionally, before and during this work, a slope is cut with a mountain wedge, a scoop or the like, or the slope is measured by a gyro with bubbles by an assistant, A signal was sent to the operator, or the excavator operator got out of the driver's seat and applied the gradient to the slope to measure (confirm). Conventionally, it is impossible to perform a work unless a bucket operation expert who can operate the bucket while maintaining the bucket at a predetermined angle.
[0006]
[Problems to be solved by the invention]
The above-described conventional method interrupts the operation of the excavator many times, and is very inefficient even if a person skilled in excavation operation is used. Further, as described above, since it is necessary to use a person skilled in shovel operation, the labor cost is increased (the cost is further increased when an assistant is required).
[0007]
The present invention solves the above problem, and even if the person is not skilled in shovel operation and does not use an assistant, the bucket can be efficiently operated so that the slope becomes a predetermined slope. An object of the present invention is to provide a slope indicator that can be used.
[0008]
[Means for Solving the Problems]
In order to achieve the above object, the present invention provides a rotating unit in which the rotating position of the rotating unit and the reference position of the reference unit are visible to the shovel operator and the weight unit is positioned in the vertical direction. The excavator is operated so that the position of the reference portion and the reference position of the reference portion at this time coincide with each other, and at that time, the pivoting range of the turning portion with respect to the reference position of the reference portion is regulated to be adjustable by the shaking portion. did.
[0009]
In this way, even if the shovel is operated, the rotating portion is always maintained at a fixed position (a state where the weight portion is positioned in the vertical direction) by the weight portion, so that the reference position matches the rotating position. If the excavator is operated while observing the rotating part and the reference part, it is not necessary for the shovel operator to step down from the cockpit and check the angle of the bucket, an assistant is unnecessary and the excavator rotates. Since the swing range of the part is adjusted and a large shake is suppressed, the work can be performed quickly.
[0010]
DETAILED DESCRIPTION OF THE INVENTION
The slope slope indicator of the present invention includes a support portion attached to a part of the bucket facing the shovel operation seat, and a reference portion fixed to the support portion and capable of displaying the reference position so as to face the shovel operation seat. A rotation part fixed to the support part so as to rotate with respect to the reference part and capable of displaying the rotation position, a weight part provided on the rotation peripheral surface of the rotation part, and a reference of the reference part And a bracing part that regulates the pivoting range of the pivoting part relative to the position in an adjustable manner.
[0011]
According to said structure, a slope slope indicator is attached to a part of bucket which faces a shovel operation seat via a support part. In the slope gradient indicator, the reference portion rotates with respect to the rotating portion that is maintained in a state where the weight portion is directed in the vertical direction in accordance with the bucket operation.
[0012]
Before the work to level the slope to the specified slope, operate the bucket to make the slope slope, write the reference position on the reference section so that it can be seen from the excavator's cockpit, and rotate it so that it matches the reference position of the reference section. The rotation position is marked on the moving part. When the bucket is operated during the operation of leveling the slope to a predetermined gradient, the rotation position is accordingly shifted with respect to the reference position (the rotation position is always the vertical position of the weight portion. The operation shifts the reference position with respect to the rotation position).
[0013]
The shovel operator can visually recognize the operator from the cockpit when the rotation position is deviated from the reference position. Therefore, the operation of leveling the slope to a predetermined gradient is not necessary if the excavator operator steps down the pilot seat one by one and confirms the angle of the bucket by operating the bucket while matching the rotation position and the reference position. In addition, the work can be performed efficiently without requiring an assistant, and the work can be performed quickly because the swinging part adjusts the turning range of the turning part to suppress a large shake. Further, even if the excavator operator is not a skilled person, if the excavator can be operated to some extent, the work can be performed reliably and accurately.
[0014]
【Example】
Embodiments of the present invention will be described below with reference to the drawings. 1 to 6 show a configuration of a slope gradient indicator of the present invention. FIG. 7 shows a state in which the slope indicator of the present invention is attached to the bucket of the shovel. FIG. 8 shows another configuration of the slope gradient indicator of the present invention.
[0015]
The slope slope indicator 1 of the present invention has the following configuration. In the bucket B of the shovel P, the mounting portion of the support portion 2 is attached to a part of the bucket facing an unillustrated shovel operation seat, that is, to the horizontal wall edge of the excavating portion of the bucket B as shown in FIG. Part 2A is attached.
[0016]
The mounting portion 2A includes a mounting piece 2Aa and a mounting bracket 2Ab. The mounting piece 2Aa has a predetermined bolt hole at one end and a plurality of bolt holes at the other end, and the mounting bracket 2Ab has a bolt hole formed on a U-shaped opposing surface. The mounting bracket 2Ab is connected to the mounting piece 2Aa with a bolt and a nut, with the bolt hole formed on one surface of the opposing surface communicating with the bolt hole at one end of the mounting piece 2Aa. Of course, it may be integrated by welding.
[0017]
And as for mounting bracket 2Ab, the wall edge part of the bucket B is inserted in the U-shaped trough part. When a bolt is inserted into a bolt hole formed on the other side of the opposite surface of the mounting bracket 2Ab and the bolt is tightened, the edge of the wall portion of the bucket B is pressed against the one surface by the bolt, whereby the mounting portion 2A (The whole slope indicator 1) is attached to the bucket B.
[0018]
Furthermore, the support portion 2 is attached to the attachment portion 2A at an angle of 90 ° in the present embodiment. The mounting portion 2B has a mounting piece 2Ba and a mounting bracket 2Bb. The attachment piece 2Ba has a plurality of bolt holes formed from one end in the longitudinal direction toward the other end. And the bolt hole of attachment piece 2Ba and the bolt hole of the other end part of attachment piece 2Aa are connected, and both are united with a volt | bolt and a nut.
[0019]
The position of the bolt hole of the mounting piece 2Ba is shifted with respect to the bolt hole of the other end of the mounting piece 2Aa, and the position of the bolt hole of the mounting piece 2Aa is shifted with respect to the bolt hole of the mounting piece 2Ba. Thus, the mounting position of both can be adjusted. Of course, welding may be used to integrate the mounting piece 2Aa and the mounting piece 2Ba. However, in the case of the configuration of this embodiment, the mounting position of both can be adjusted as described above, and the mounting piece 2Aa can be removed. Therefore, there is an advantage that it can be downsized for carrying.
[0020]
In addition, a mounting bracket 2Bb is mounted on the mounting piece 2Ba from the middle position in the longitudinal direction toward the other end. In this embodiment, between the mounting pieces 2Ba and the mounting bracket 2Bb, for example, a circular shape, and a reference portion 3 in which a reference position 3A is written at a position facing the cockpit of the shovel P, for example, a reference portion 3 Similarly, it has a circular shape and is rotated with respect to the reference portion 3 and is provided with a rotating portion 4 on which a rotating position 4A is marked.
[0021]
In the present embodiment, the reference portion 3 has a bottomed cylindrical body on one end side, and its shaft is fixedly supported by the mounting bracket 2Bb. Moreover, the reference | standard part 3 has described the reference | standard position 3A by sticking the seal | sticker S etc. on the position which can be seen from the cockpit of the shovel P in the surrounding surface. The reference position 3A can be arbitrarily adjusted. For example, the reference position 3A is appropriately adjusted according to the slope work slope of the bucket B or the positional relationship between the bucket B and the cockpit of the shovel P. To do.
[0022]
In the present embodiment, the rotating portion 4 has a bottomed cylindrical body, and its shaft is pivotally supported between the mounting piece 2Ba and the mounting bracket 2Bb. Further, on the rotation peripheral surface of the rotation unit 4, a rotation position 4 </ b> A set by a procedure described later so as to coincide with the reference position 3 </ b> A of the reference unit 3 is described by attaching a tape T, for example. . The tape T indicating the rotation position 4A also serves as a constituent element of a later-described steadying portion 6. Furthermore, a weight portion 5 having a predetermined weight is provided on the rotation peripheral surface of the rotation portion 4.
[0023]
Further, the rotation range of the rotation unit 4 is restricted to about ± 45 ° by a rocking unit 6 provided at the other end of the mounting piece 2Ba . When the weight portion 5 is sufficiently heavy, it is more greatly rotational unit 4 can without touching, but also the weight portion 5 as soon as shake you still in a state oriented in a vertical direction.
[0024]
Futome section 6, if the weight of the weight portion 5 is light or is pressurized with a large deflection of the rotation unit 4 for further rapid work suppressed. The brace 6 has the tape T provided with a certain degree of bending along the circumferential surface of the pivot part 4 from the position indicating the pivot position 4A. In addition, since this tape T has the one end part variably showing the rotation position 4A, and the other end part is variably attached to the peripheral surface of the rotation part 4, each can be bonded. .
[0025]
Furthermore, the anti-vibration part 6 is comprised so that the bending amount of the tape T may be adjusted with the adjustment part 6A provided in attachment piece 2Ba. The adjustment portion 6A includes a substrate 6Aa attached to the attachment piece 2Ba and an adjustment plate 6Ab provided on the substrate 6Aa, and is configured to screw them.
[0026]
The adjusting portion 6A loosens the screw to widen the distance between the substrate 6Aa and the adjusting plate 6Ab, adjusts the amount of bending of the tape T, and then tightens the screw again to place the tape T between the substrate 6Aa and the adjusting plate 6Ab. It has a structure to sandwich. At this time, the position of the other end of the tape T is pasted to an arbitrary adjustment position on the peripheral surface of the rotating unit 4.
[0027]
By providing this bracing portion 6, the weight portion 5 suppresses the swinging portion 4 from continuing to swing for a long time, and it is visually confirmed that the reference position 3 </ b> A and the turning position 4 </ b> A are coincident or shifted. It becomes possible to determine immediately.
[0028]
The slope slope indicator 1 having the above configuration is used as follows. First, the slope gradient indicator 1 is attached to the bucket B of the shovel P as shown in FIG. At this time, the positions of the attachment portion 2A and the attachment portion 2B in the support portion 2 are adjusted so that the reference position 3A of the reference portion 3 and the rotation position 4A of the rotation portion 4 can always be seen from the cockpit of the shovel P. Keep it.
[0029]
After that, the bucket B is operated so as to have a slope of a working slope, and the bucket B is held when the bucket B is operated to a predetermined slope. Next, the adjusting unit 6A of the swinging unit 6 is operated to bring the tape T into a free state and wait until the weight unit 5 is positioned in the vertical direction. When the weight part 5 is positioned in the vertical direction, the position of the rotation part 4 with respect to the reference part 3 is determined, and at this time, the seal S at the reference position 3A is attached to a position that coincides with the rotation position 4A.
[0030]
Further, in order to determine the amount of rotation (swing amount) of the rotation unit 4, the other end portion of the tape T (the opposite end to the rotation position 4 </ b> A) is placed on the peripheral surface of the rotation unit 4 while considering the amount of bending. Re-apply in position. Thereafter, the adjusting portion 6A of the anti-vibration portion 6 is operated to sandwich the tape T between the substrate 6Aa and the adjusting plate 6Ab.
[0031]
After the above setting, the slope is leveled to a predetermined slope. When the bucket B is operated during this work, the slope slope indicator 1 moves as the bucket B moves. At this time, the rotation unit 4 always tries to position the weight unit 5 in the vertical direction by the weight unit 5, so that when the bucket B is operated, the amount of movement of the bucket B (reference unit 3) relative to the rotation position 4 </ b> A is small. This can be grasped by viewing the reference position 3A.
[0032]
In other words, the reference position 3A and the rotation position 4A in the slope slope indicator 1 of the present invention are visually observed, and the bucket B is operated so that the reference position 3A matches the rotation position 4A. The slope can be leveled so as to have a gradient.
[0033]
Further, when the bucket B is operated, the rotating unit 4 rotates as the bucket B moves. However, since the rotating unit 4 is restricted to a predetermined range by the anti-vibration unit 6, it does not rotate (shake) more than necessary. Since the weight part 5 immediately stops the vibration (positioned in the vertical direction), it is not necessary to wait until the vibration of the rotating part 4 stops, and the slope can be smoothly leveled to a predetermined gradient.
[0034]
The slope slope indicator 1 of the present invention is not limited to the above configuration, and various modifications are possible. For example, the attachment piece 2Aa of the attachment portion 2A and the attachment piece 2Ba of the attachment portion 2B may be configured as shown in FIG. That is, in FIG. 8, guides 21A and 21B are formed at the attachment positions of the attachment piece 2Aa and the attachment piece 2Ba. These guides 21A and 21B are communicated (adjusted) and fixed with bolts and nuts via a fixing plate 22.
[0035]
By comprising in this way, the attachment angle of attachment piece 2Aa and attachment piece 2Ba can be adjusted, and an attachment position can be set in detail. In particular, by making the mounting angle variable, it is only necessary to determine the mounting angle of the mounting piece 2Ba with respect to the mounting piece 2Aa so that the reference position 3A and the rotation position 4A coincide. Accordingly, the reference position 3A and the rotation position 4A can be described in a fixed manner, and the amount of deflection of the rotation unit 4 by the anti-vibration unit 6 can be determined in a fixed manner. It becomes possible to install and use.
[0036]
Hereinafter, the result of comparing the case of using the conventional method and the case of using the slope gradient indicator 1 of the present invention regarding the work of leveling the slope to a predetermined gradient will be described.
[0037]
(Before work)
Conventional: The slope is cut with hoes, scoops, etc., or a skilled assistant is required, which is quite laborious.
The present invention: An assistant is unnecessary, hoes and scoops are not required, and only a stand-by mark is required with only the ray as a mark.
[0038]
(When working)
Conventional: If an assistant is required, check with a gradient device one by one. When an assistant is not required, the excavator operator gets out of the cockpit, measures himself, and works while checking each one.
The present invention: An assistant is unnecessary, and if the slope slope indicator 1 of the present invention is set, the excavator operator does not need to step down from the cockpit and check it by himself.
[0039]
As a result of the above, according to the present invention, the work efficiency is more than doubled as compared with the prior art, the assistant is unnecessary, the work efficiency is improved and the work period is shortened, and not a skilled shovel operator. However, it was found that it was economically superior because it was possible to work.
[0040]
【The invention's effect】
As described above, the slope indicator of the present invention allows the excavator operator to visually recognize the rotation unit and the reference position of the reference unit, and the position of the rotation unit with the weight unit positioned in the vertical direction. And the reference position of the reference part at this time should be operated, so that it is not necessary for the shovel operator to go down the pilot seat and check the bucket angle one by one, and no assistant is required. Furthermore, since the pivoting range of the pivoting part is adjusted by the swinging part to suppress a large shake, the work can be performed quickly, so that the work can be performed efficiently and not a skilled shovel operator. Can work reliably and accurately.
