Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a breaker holding device capable of holding breakers (rock drilling machine) used when performing work such as rock drilling and excavation.

[0002]

[Prior art]

 A breaker such as a rock drill used when excavating roads vibrates a bit attached to the tip of the breaker by an engine or a motor provided in the breaker and pushes the bit against the object to be excavated. The object to be excavated is destroyed by hitting and excavation work is performed. For example, when excavating an asphalt-paved road using such a rock drill, an operator supports the breaker body by holding the handle attached to the top of the breaker, and The provided bit is pressed against the asphalt and the breaker is driven to destroy the asphalt and excavate the road.

[0003]

[Problems to be solved by the device]

 In this case, if the asphalt is destroyed, the bit will be buried in the destroyed asphalt, so the breaker must be lifted and moved to excavate elsewhere. Therefore, if the road to be excavated is wide, the operator must repeatedly lift and move the breaker. However, since the breaker is equipped with the engine and the like as described above, the breaker is heavy, and the breaker itself vibrates when it is driven, and the operator is physically tired and cannot work for a long time. was there.

In addition, when excavating a wall surface or the like, the worker must always support the breaker and press it against the wall surface, which further increases the fatigue of the worker. It was happening.

The present invention has been made in view of the above problems, and provides a breaker holding device capable of reducing physical fatigue of an operator when performing work using breakers. Is intended.

[0006]

[Means and Actions for Solving the Problems]

 In order to achieve the above object, the breaker holding device according to the present invention is provided with a holding means for holding the breaker in the balancer device by grasping the breaker from the side and the upper side, and the balancer device reduces the weight of the breaker. It has a balance that can be offset. In such a breaker holding device, since the weight of the breaker is made weightless by the balancer device, an operator can easily lift the breaker and support it in a vertical state.

【Example】

 Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings. First, a working vehicle equipped with a breaker holding device according to the present invention will be described with reference to FIG. The work vehicle 31 is a truck-type work vehicle having a loading platform 32 on the rear part of the vehicle body, and various working equipments are loaded on the loading platform 32, and the working vehicle 31 is moved to a construction site to perform work. Further, the breaker holding device 1 is provided at the rear of the loading platform 32.

As shown in detail in FIG. 1, the breaker holding device 1 includes a swivel base 11 that swivels itself with respect to a loading platform 2 and a base end that is pivotally attached to the swivel base 11 so as to be capable of undulating. A balancer device 10 including a tip arm 13 pivotably attached to the arm 12 and the base arm 12, and holding means 14 provided to hold the breaker 20 at the tip of the tip arm 13. Consists of. The base arm 12 and the tip arm 13 are a so-called parallel link mechanism composed of two arm members, respectively.

The holding means 14 includes a pair of left and right side holding members 15a and 15b provided for holding the main body of the breaker 20 from the side, and left and right handle portions 20a and 20a of the breaker 20 from above, respectively. It is composed of a pair of left and right upper holding members 16a and 16b provided for holding. The side holding members 15a and 15b can be opened and closed left and right, as shown by the arrow in FIG. 1, and the upper holding members 16a and 16b can be opened and closed similarly. Here, these holding members have a built-in spring so that force acts in the closing direction, so that the holding state can be maintained, and thus the breaker can be gripped. As a method for maintaining the closed state of each holding member, a spring may be used as described above, or a lock pin or the like may be inserted.

One end of a suspension 17 is swingably attached to the swivel base 11, and the other end of the suspension 17 is pivotally attached in the vicinity of a pivotal connection portion of the base end arm 12 with the swivel base 11. Further, the respective ends of the suspension 18 are pivotally attached to the pivotal portions of the proximal arm 12 and the distal arm 13 in the vicinity of the pivotal portions. These suspensions 17 and 18 correspond to the balance force imparting device described in the claims, but these suspensions are composed of springs for imparting a balance force and dampers for absorbing vibration. ing.

Next, a case where a road excavating operation is performed using the breaker holding device 1 configured as described above will be described. First, the work vehicle 31 is stopped near the road where the excavation work is performed, and the side holding members 15a and 15b provided in the holding means 14 are opened left and right, and the upper holding members 16a and 16b are opened upward. Then, the breaker 20 is set on the holding means 14 so that the handles 20a, 20a of the breaker 20 are located above the side holding members 15a, 15b, and the upper holding member 16a located above the handles 20a, 20a. , 16b are closed downward, and the side holding members 15a, 15b are closed toward the breaker 20. Accordingly, the breaker 20 is held by being held by the breaker holding device 1 from the side and the upper side. Then, the operator operates the breaker 20 and positions the bit 20b at a desired position to perform excavation work.

In this case, since the weight of the breaker 20 is offset by the action of the springs provided on the suspensions 17 and 18, the force for the operator to lift the breaker 20 during excavation work can be reduced. Further, the dampers provided in the suspensions 17 and 18 can reduce the vibration of the breaker 20 transmitted to the worker. Further, since the arm portions 12 and 13 of the balancer device 10 holding the breaker 20 are configured to freely swing and swing as described above, the breaker 20 can also be freely moved in the horizontal direction. . As a result, the physical fatigue of the worker can be reduced and it becomes possible to work for a long time.

In the above case, the breaker 20 is held vertically and the road is excavated. However, in the breaker holding device 1 according to the present invention, the breaker holding means 14 is attached to the tip arm 13. Since the rocker can be swung and rotated freely, it is possible to hold the breaker 20 horizontally and excavate the wall surface. In this case, the operator need only press the breaker 20 against the wall surface, and it is not necessary to support the weight of the breaker 20 itself, so that physical fatigue can be further reduced.

In the above-described embodiment, the spring provided in the suspension is used as the balancing force applying device, but the present invention is not limited to this, and an actuator using hydraulic pressure or pneumatic pressure is used. May be.

When the breaker held by the holding means has a motor driven by hydraulic pressure or electricity, the hydraulic hose or the power cord can be arranged via the arm portion of the balancer. Therefore, these hoses will not be located on the road to be excavated and will not hinder the work.

[0016]

[Effect of device]

 As described above, the breaker holding device according to the present invention has the holding means for holding the breaker by grasping the breaker from the side and the upper side and the balance force capable of canceling the weight of the breaker held by the holding means. Balancer device. This eliminates the need for the operator to support the weight of the breaker during excavation work, which can reduce the physical fatigue of the operator.
