Description

Height-Adjustable Auxiliary Pedal for Construction Machinery

The present invention relates to a height-adjustable auxiliary pedal for a construction machine, and more specifically, a height-adjustable auxiliary pedal for a construction machine that can variably adjust the height or ankle angle of an auxiliary pedal installed on both left and right sides of a driving pedal. It is about.

Fixed driving pedal according to the prior art shown in Figure 1,

Construction equipment such as an excavator is equipped with a driving pedal 2 and a driving control lever 3 in front of the driver's seat 1 so as to control the driving of the driving motor. The auxiliary pedal 4 is mounted on both left and right sides of the pedal 2.

In the figure, reference numeral 6 is an adjustment lever (RCV lever) mounted on the left and right sides of the driver's seat 1 so as to operate a work device such as a boom or an arm.

At this time, the auxiliary pedal (4) is fixed to the bottom plate of the cab cap (5) in a fixed manner that can not control the height of the variable, so that only the height of the driver's seat (1) driver's convenience (physical body conditions, etc.) After driving to adjust to fit). That is, the situation where the height of the driver's seat 1 is adjusted to adjust the height of the driver's knee so as to secure various viewing angles required for driving.

In this way, only the height of the driver's seat 1 is adjusted to meet the limit of the optimized knee height of the driver having various body conditions. Therefore, it is impossible to maintain a driving posture that is optimally suitable for driving equipment, which causes a problem of impairing the health of the driver's knees and spine when driving for a long time.

In addition, the height of the auxiliary pedal 4 can not be adjusted to ensure a wide viewing angle of the driver during the work, the driver is constantly moving in the driver's seat 1 during the operation, there is a problem inferior in workability.

Embodiment of the present invention, the height adjustable or ankle angle of the auxiliary pedals installed on both the left and right sides of the driving pedal to adjust the height to fit the driver's convenience to adjust the height adjustable for construction machinery to ensure a variety of angles of view It is related to the pedal.

Embodiment of the present invention, by adjusting the height of the auxiliary pedal to maintain the optimum posture suitable for driving to improve workability due to a stable posture, protect the ankle, knee or spine, correct correct driving posture It is related to a height adjustable auxiliary pedal for a construction machine.

Height-adjustable auxiliary pedal for construction machinery according to an embodiment of the present invention,

In the auxiliary pedals installed on both the left and right running pedals of construction machinery,

Control switch,

A drive motor driven by control switch operation,

A cam installed on the rotating shaft of the drive motor, the cam moving by the drive motor;

A rod linked with the cam driving to convert the rotational movement of the cam into a linear movement,

And an auxiliary pedal mounted to the upper end of the rod.

According to a preferred embodiment, the above-described control switch is provided in the switch box mounted in the cab.

As the above-described drive motor

According to the operation of the control switch, a hydraulic motor driven by hydraulic oil supplied from the hydraulic pump is used.

As the above-described drive motor

According to the operation of the control switch, an electric motor driven by the power supplied from the battery is used.

As the electric motor described above, a stepping motor is used.

And a guider mounted to the cab cap bottom plate to guide the linear motion of the rod in the vertical direction.

Height-adjustable auxiliary pedal for construction machinery according to an embodiment of the present invention configured as described above has the following advantages.

Since the height of the auxiliary pedals installed on both the left and right sides of the driving pedal is variably adjusted, the seat and the auxiliary pedals can be adjusted to optimal conditions to suit the driver's convenience, thereby securing various angles of view. In addition, long-term drivers can maintain the optimal driving posture, so that stable posture improves workability, protects the ankle, knee and spine, and corrects the correct driving posture.

Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings, which are intended to explain in detail enough to enable those skilled in the art to easily carry out the invention, and thus It is not intended that the technical spirit and scope of the invention be limited.

Height-adjustable auxiliary pedal for a construction machine according to an embodiment of the present invention shown in Figure 2 and 3,

In the auxiliary pedals provided on both the left and right sides of the traveling pedal of construction machinery such as an excavator,

A control switch 11 for controlling the power of the battery 10,

A driving motor 12 mounted below the cab cap bottom plate a (that is mounted on the upper frame) and driven by power supplied from the battery 10 due to the operation of the control switch 11 (example) As a stepping motor, etc.),

A cam 14 installed on the rotary shaft 13 of the drive motor 12 and cam-driven by driving the drive motor 12,

A rod 15 which is moved upward and downward on the cab cap bottom plate a and which is interlocked when the cam 14 is driven to convert the rotational movement of the cam 14 into a linear movement,

An extra pedal 16 is mounted to the upper end of the rod 15.

In this case, the aforementioned control switch 11 may be provided in the switch box 17 mounted in the cab 5.

Although not shown in the figure, as the above-described drive motor 12

According to the operation of the control switch 11, a hydraulic motor driven by hydraulic oil supplied from a hydraulic pump (not shown) may be used.

Although not shown in the figure, it may include a guider mounted to the cab cap bottom plate (a) to guide the linear motion of the rod 15 in the vertical direction.

In the figure, reference numeral 18 is a power cable for connecting the control switch 11 and the drive motor 12.

Hereinafter, with reference to the accompanying drawings an example of the use of the height-adjustable auxiliary pedal for construction machinery according to an embodiment of the present invention will be described in detail.

2 and 3, as the driver operates the control switch 11 installed in the switch box 17 mounted to the left and right sides of the driver's seat 1 in an ON state, the battery 10 The drive motor 12 is driven by the power supplied from the. Since the rotary shaft 13 is rotated by the driving of the drive motor 12, the cam 14 installed on the rotary shaft 13 is cam-moved. The rotational motion of the cam 13 is converted into a linear motion by the rod 15 interlocked according to the cam motion of the cam 13.

At this time, the rod 15 is a smooth linear movement in the up and down direction by a guider (not shown) mounted to the cab cap bottom plate (a). Therefore, the auxiliary pedal 16 mounted on the top of the rod 15 can be moved in the up and down directions. As a result, the driver of the driver's seat 1 can variably adjust the height of the auxiliary pedal 16 that can maintain an optimal driving posture suitable for driving. Therefore, when the driver switches to the work mode while driving, the driver can maintain a comfortable posture by placing his foot on the auxiliary pedal 16 whose height is adjusted to suit the driver's body shape condition.

As described above, the driver can adjust the height of the auxiliary pedal 16 by the operation of the control switch 11 to maintain an optimal driving posture, and tilt the height of the driver's seat 1, etc. (not shown). By variable adjustment by the above, various viewing angles required for the work can be secured.

Therefore, because of the characteristics of the equipment, even when driving for a long time to maintain a stable driving posture to improve the work efficiency, and adjust the height of the auxiliary pedal 16 to correspond to the physical body conditions of the driver, so that excessive force on the ankle, spine, etc. Can be prevented.

According to the present invention having the above-described configuration, since the height of the auxiliary pedal installed on one side of the driving pedal is variably adjusted, the seat and the auxiliary pedal can be adjusted after driving to maintain the optimum driver's posture for the driver's convenience. A driver who has been driving for a long time maintains an optimized posture, so a stable posture improves workability and protects the ankle, knee or spine.
