Description

Technical Field

[0001] The present invention relates to an engineering machine, and more particularly, to an engineering machine provided with an auxiliary information display lamp. Background Art

[0002] Construction machinery refers to all machines used in civil engineering or construction. Generally speaking, construction machinery has an engine and a hydraulic pump that uses the power of the engine to operate, and uses the hydraulic oil discharged by the hydraulic pump to travel or drive various working devices. In addition, construction machinery is equipped with a variety of attachments depending on the type of work to be performed. For example, an excavator, which is a type of construction machinery, is selectively equipped with various attachments such as a bucket for excavation, a breaker, a vibrator, and a hammer at one end of the boom for use.

[0003] Thus, construction machinery not only travels for the purpose of moving, but also performs work at various work sites.

[0004] However, in the past, when a construction machine was working at a construction site, the current working status was displayed by a warning light (Beacon). In addition, such a warning light is configured so that the operator can choose to turn it on / off (on / off) by means of a switch. Therefore, in the construction site, construction machines that are working with the warning light on and those that are working with the warning light off are mixed together, and there is a problem that other operators working around the construction machine find it difficult to know the current working status of the construction machine at a glance. In addition, there is a problem that it is difficult to clearly distinguish the type of work that the construction machine is working on and the work preparation state or the working state.

[0005] In addition, when the construction machine is moving on the road, the operator often operates the working device to align the equipment or lower or raise the boom. In this case, there is also a problem that the rear or surrounding vehicles of the construction machine cannot recognize the operation status of the construction machine, which may cause an accident. Summary of the invention

[0006] Technical issues

[0007] An embodiment of the present invention provides an engineering machine capable of auxiliary displaying the current state to the surroundings for warning through a multifunctional auxiliary information display lamp.

[0008] Technical Solution

[0009] According to an embodiment of the present invention, the construction machinery includes a traveling body, a swinging body that can be swingably arranged on the traveling body, and a working device arranged in front of the swinging body. In addition, the construction machinery includes: a brake light that is arranged at both ends behind the swinging body and is lit in response to the braking of the traveling body; an auxiliary information display light that is arranged laterally longer on the upper side of the brake light behind the swinging body; an object sensing unit that senses the surrounding objects of the construction machinery; a swing motion sensing unit that senses the rotation of the swinging body; and a control device that lights up the auxiliary information display light or flashes the auxiliary information display light in one of a plurality of patterns set differently from each other according to information transmitted from the object sensing unit and the swing motion sensing unit, and controls the auxiliary information display light so that the auxiliary information display light is preferentially lit corresponding to the brake signal.

[0010] The auxiliary information display lamp may include a plurality of light emitting diodes (LEDs) which are arranged to be long in a transverse direction and can be independently lit.

[0011] The engineering machine may further include a driver's seat disposed on the front side of the swing body. In addition, the auxiliary information display light may be disposed so as to overlap the driver's seat instead of the brake light in the vertical direction when viewed from the rear.

[0012] In addition, the engineering machine may further include: an engine room disposed at the rear of the swing body; and an engine room cover for protecting and opening and closing the engine room. In addition, the auxiliary information display light may be disposed on the engine room cover, and the brake light may be disposed on the swing body except for the engine room cover.

[0013] Furthermore, the construction machine may further include an operating device having an operation mode selection unit for selecting the use of the working device. Furthermore, when the operation mode is selected by the operation mode selection unit, the auxiliary information display lamp may be lit.

[0014] The multiple patterns may include: a pattern in which, when the rotating body is in a rotating action state, the auxiliary information display light is repeatedly lit or flashed in sequence from one end to the other end; and a pattern in which the auxiliary information display light repeats flashing as a whole when an object is sensed around the traveling body.

[0015] The control device may display the turning operation state on the auxiliary information display lamp with priority over a case where an object is sensed around the traveling body.

[0016] When the gyratory body is in a gyratory motion state, the pattern displayed by the auxiliary information display lamp may be executed for a set time before or after the gyratory body gyrates.

[0017] The construction machine may further include a work standby state sensing unit for sensing the work standby state of the work device. In addition, the control device may further reflect information transmitted from the work standby state sensing unit when lighting or flashing the auxiliary information display light.

[0018] The object sensing unit may include an ultrasonic sensor or a motion recognition sensor, and the object sensing unit is disposed at the rear of the engineering machine to sense objects at the rear.

[0035] Furthermore, expressions such as “first”, “second”, etc. used in the present specification are used to distinguish a plurality of constituent elements from one another, and do not limit the order or importance of these constituent elements.

[0036] Refer to the following Figures 1 to 6 A construction machine 101 according to an embodiment of the present invention will be described.

[0037] For example, the construction machine 101 may be an excavator. Figure 1 As shown, the construction machine 101 may include a traveling body 121 for traveling, a swing body 110 swingably provided on the upper portion of the traveling body 121 , and a working device 150 provided in front of the swing body 110 .

[0038] The traveling body 121 supports the slewing body 110, and the driving device can drive the engineering machine 101 by using the power generated by the engine. In the first embodiment of the present invention, the traveling body 121 can be a wheeled type having a plurality of driving wheels. That is, the wheeled engineering machine 101 can also travel on general roads.

[0039] The gyratory body 110 can rotate on the traveling body 121 and set the working direction. In addition, the gyratory body 110 can be provided with an operating device 400 (shown in FIG. Figure 3 ) of the driver's seat 115. For example, the driver's seat 115 may be disposed on the front side of the swing body 110. In addition, the swing body 110 may be provided with an engine for generating power and a hydraulic pump for supplying working oil to various drive devices through the engine.

[0040] Furthermore, an engine room 112 may be disposed at the rear of the revolving body 110 , and an engine room cover 114 for protecting and opening and closing the engine room 112 may be provided at the rear of the engine room 112 .

[0041] In addition, the auxiliary information display lamp 200 to be described later may be disposed on the engine hood 114, and the brake lamp 800 to be described later may be disposed on the swing body 110 other than the engine hood 114. That is, the auxiliary information display lamp 200 and the brake lamp 800 may be disposed in separate components.

[0042] However, the first embodiment of the present invention is not limited thereto. Figure 2 As shown, the auxiliary information display lamp 200 and the brake lamp 800 may be disposed together on the engine hood 114 .

[0043] The working device 150 may include a boom, an arm, a bucket, and a boom cylinder for controlling the movement of the boom, an arm cylinder for controlling the movement of the arm, and a bucket cylinder for controlling the movement of the bucket. In addition, as the working device 150, instead of a bucket, a plurality of attachments including a tilt rotator, a shovel, a breaker, a vibrator, and a hammer may be selectively installed on the construction machine 101 according to the type of work. In addition, the working device 150 may also include an optional cylinder, etc.

[0044] In addition, if Figure 2 As shown, a brake light 800 and an auxiliary information display light 200 may be provided at the rear of the rotating body 110 .

[0045] like Figure 3As shown, in addition to the brake light 800 , the auxiliary information display light 200 , and the operating device 400 mentioned above, the engineering machinery 101 of the first embodiment of the present invention may also include an object sensing unit 340 , a rotation motion sensing unit 330 , and a control device 700 .

[0046] In addition, the construction machine 101 may further include a work standby state sensing unit 320 , a work motion sensing unit 350 , a work travel determination unit 310 , and a brake signal sensing unit 360 .

[0047] The brake lights 800 are provided at both ends behind the revolving body 110 , and are lit in response to braking of the traveling body 121 .

[0048] The auxiliary information display lamp 200 may be disposed laterally long on the upper side of the brake lamp 800 behind the gyro 110. Specifically, the auxiliary information display lamp 200 may include a plurality of light emitting diodes (LEDs) disposed laterally long and capable of being independently lit. Therefore, in the first embodiment of the present invention, the auxiliary information display lamp 200 may be lit or flashed in one pattern selected from a plurality of patterns set differently from each other. Here, the plurality of patterns that the auxiliary information display lamp 200 may display will be described in detail later.

[0049] Furthermore, the auxiliary information display lamp 200 may be arranged so as not to overlap with the brake lamp 800 in the vertical direction but to overlap with the driver's seat 115 arranged on the front side of the revolving body 110 when viewed from the rear of the construction machine 101 .

[0050] For example, Figure 1 In the figure, A is a section where the auxiliary information display lamp is provided, B is a section where the brake lamp is provided, and C is a section where the driver's seat is provided. That is, A may be arranged so as not to overlap with B in the vertical direction but to overlap with C.

[0051] In this way, the auxiliary information display lamp 200 can be formed longer and is configured to improve information transmission capability while being clearly distinguished from the brake lamp 800 so that information transmission does not become confusing.

[0052] The object sensing unit 340 can sense the surrounding objects of the construction machine 101. Here, the surrounding of the construction machine 101 may include the rear or side rear of the traveling body 121. For example, the object sensing unit 340 includes one or more of an ultrasonic sensor or a motion recognition sensor, and can be arranged at the rear of the construction machine 101 to sense the objects at the rear. The auxiliary information display lamp 200 has a large function of notifying an external operator at the rear, so it is important to sense the objects at the rear.

[0053] The work standby state sensing unit 320 can sense the work standby state of the work device 150. For example, the work standby state sensing unit 320 may include a pressure sensor for controlling the pilot pressure of the supply of the working oil to the work device 150, an operation signal sensing unit for sensing an operation signal for the operation device 400 to be described later to operate the work device 150, and one or more of a limit sensor or a motion sensing sensor for physically sensing the motion of the work device 150.

[0054] Specifically, in the construction machine 101, the supply of the working oil discharged by the hydraulic pump to the working device 150 can be controlled by the pilot pressure formed according to the operation signal of the operating device 400. Therefore, it is possible to sense whether the working device 150 is currently working or in a working standby state by sensing the pilot pressure for controlling the supply of the working oil to the working device 150. In addition, it is also possible to sense whether the working device 150 is currently working or in a working standby state by sensing the operation signal of the operating device 400 or directly sensing the movement of the working device 150.

[0055] The swing motion sensing unit 330 can sense the rotation of the swing body 110. For example, the swing motion sensing unit 330 may include an operation signal sensing unit that senses an operation signal for operating the swing motion of the swing body 110 by the operating device 400 to be described later, a pressure sensor that senses a pilot pressure of the supply of working oil for controlling the swing motion of the swing body 110, an angular displacement sensor that measures the rotation angle of the swing body 110, a rotation sensor that senses the rotation of the swing body 110, a non-contact motion sensing sensor, and one or more of a limit sensor that physically senses the motion of the swing body 110.

[0056] Specifically, in the construction machine 101, the supply of the working oil discharged by the hydraulic pump to the swing motor can be controlled by the pilot pressure formed according to the operation signal of the operating device 400. Therefore, it is possible to sense whether the swing body 110 is currently performing a swing action by sensing the pilot pressure used to control the supply of the working oil to the swing motor. In addition, it is also possible to sense whether the swing body 110 is currently performing a swing action by sensing the swing operation signal of the operating device 400 or directly sensing the swing action of the swing body 110.

[0057] The working motion sensing unit 350 can sense the current motion of the working device 150. For example, the working motion sensing unit 350 may include one or more of a pressure sensor for sensing a pilot pressure for controlling the supply of working oil to the working device 150, a pressure sensor for sensing the pressure of the working oil supplied to the working device 150, a motion recognition sensor for sensing the motion of the working device 150, a displacement sensor, and a limit sensor.

[0058] Specifically, the working device 150 may include a hydraulic cylinder, and the working device 150 may sense what kind of work is currently being performed by sensing the pilot pressure for controlling the supply of the hydraulic oil discharged by the hydraulic pump to the hydraulic cylinder. In addition, the working device 150 may also sense what kind of work is currently being performed by sensing the pressure of the hydraulic cylinder or directly sensing the movement of the working device 150.

[0059] The operation driving judgment unit 310 can sense whether the construction machine 101 is currently in the driving mode or the working mode. For example, the operation driving judgment unit 310 can use the operation signal for the operation device 400 to operate the driving of the driving body 121 or the operation of the working device 150 to be described later to judge whether it is working or driving, or can use the speed sensor installed on the driving body 121 to judge whether it is driving.

[0060] The brake signal sensing unit 360 can sense the brake signal. For example, the brake signal sensing unit 360 may include a pressure sensor for sensing a pilot pressure for controlling the supply of working oil to the brake device, a pressure sensor for sensing the pressure of the working oil supplied to the brake device, an operation signal sensing unit for sensing an operation signal of an operation device 400 for controlling the brake device, an action recognition sensor for sensing the action of the brake device, a displacement sensor, and one or more of a limit sensor.

[0061] Specifically, the brake device may also be operated using the working oil, and whether the brake device is in operation may be sensed by sensing the pilot pressure for controlling the supply of the working oil to the brake device. In addition, the pressure of the working oil supplied to the brake device may be sensed, or an operation signal of the operating device 400 for controlling the brake device may be sensed, or the operation of the brake device may be directly sensed.

[0062] The operating device 400 can operate the travel action of the travel body 121, the swing action of the swing body 110, and the working action of the working device 150, and input a brake signal for controlling the brake device. In addition, the operating device 400 can also control the operation of the auxiliary information display light 200. That is, the function of the auxiliary information display light 200 can be activated or deactivated by the operating device 400.

[0063] Furthermore, in the first embodiment of the present invention, the operating device 400 may have an operation mode selection unit for selecting the use of the operation device 150. The user can select the operation mode and the driving mode through the operation mode selection unit. When the user selects the driving mode, the construction machinery 101 can only drive; when the user selects the operation mode, the construction machinery 101 can both drive and operate. When the operation mode is selected through such an operation mode selection unit, the auxiliary information display light 200 may be turned on. Therefore, the information about whether the currently selected mode is the driving mode or the operation mode can be informed to the external operator through the auxiliary information display light 200. For example, if the brake light 800 is turned off and only the auxiliary information display light 200 is on, the external operator can know that the current construction machinery 101 is in standby in the operation mode.

[0064] The control device 700 lights up the auxiliary information display light 200 or flashes the auxiliary information display light 200 in one pattern selected from a plurality of patterns set differently from each other according to the information transmitted from the object sensing unit 340 and the rotation motion sensing unit 330, and controls the auxiliary information display light 200 so that the lighting corresponding to the brake signal is preferentially displayed.

[0065] Here, the plurality of patterns may include: a pattern in which the auxiliary information display light 200 is repeatedly lit or flashed in sequence from one end to the other end when the swing body 110 is in the swing action state, and a pattern in which the auxiliary information display light 200 as a whole repeatedly flashes when an object is sensed around the traveling body 121. At this time, the control device 700 may display the swing action state on the auxiliary information display light 200 in priority to the case where an object is sensed around the traveling body 121. In addition, when the swing body 110 is in the swing action state, the pattern displayed by the auxiliary information display light 200 may also be executed for a set time before the time point when the swing body 110 swings or after the swing ends. For example, the set time may be set in the range of 1 second to 10 seconds.

[0066] In addition, in addition to the object sensing unit 340 and the rotation motion sensing unit 330, the control device 700 can also receive information from the work standby state sensing unit 320, the work motion sensing unit 350, the work travel judgment unit 310 and the brake signal sensing unit 360, and based on this, light up the auxiliary information display light 200 or make the auxiliary information display light 200 flash in one pattern selected from a plurality of patterns set differently from each other.

[0067] For example, the plurality of patterns may include a first pattern, a second pattern, a third pattern, a fourth pattern, a fifth pattern, and a sixth pattern.

[0068] When the gyration body 110 is in the right gyration state, the first pattern can be realized. Figure 4 As shown, under the first pattern, the lighting or flashing process can be repeated in sequence from the right end to the left end of the auxiliary information display lamp 200. Figure 4 In the figure, the arrows indicate the directions in which the auxiliary information display lights are illuminated in sequence.

[0069] When the gyration body 110 is in the left gyration state, the second pattern can be realized. Figure 5 As shown, in the second pattern, the lighting or flashing process can be repeated in sequence from the left end to the right end of the auxiliary information display lamp 200. Figure 5 In FIG. 1 , arrows indicate directions in which the auxiliary information display lamps 200 are sequentially illuminated.

[0070] When the operating device 150 is in the operating state, the third pattern can be realized. Figure 6 As shown in FIG. 1 , in the third pattern, the auxiliary information display lamp 200 may flash repeatedly as a whole. Figure 6 As shown, in the third pattern, the auxiliary information display lamp 200 may flash repeatedly as a whole. Figure 6 The inner quadrilateral indicated by the dotted line in the figure shows the state where the auxiliary information display lamp 200 flashes repeatedly.

[0071] When the operation device 150 is in the operation standby state, the fourth pattern can be realized. In the fourth pattern, the auxiliary information display lamp 200 can be lit up as a whole at the same time and then maintained in the lighting state. Figure 7 The inner quadrilateral indicated by the solid line in the figure indicates a state in which the auxiliary information display lamp 200 is kept lit.

[0072] The fifth pattern may be implemented when the surrounding objects are sensed during the backward movement of the traveling body 121. Specifically, in the fifth pattern, the auxiliary information display lamp 200 as a whole may repeatedly flash at a relatively shorter period than the fourth pattern. For example, in the fifth pattern, the auxiliary information display lamp 200 may repeatedly flash at a period less than half of the third pattern.

[0073] When a brake signal is sensed during the traveling of the traveling body 121 or during the operation standby of the working device 150, the sixth pattern can be implemented. Figure 8 As shown, in the sixth pattern, the auxiliary information display lamp 200 may repeat the process of lighting up or flashing in sequence in the direction from the central area to the ends on both sides. Figure 8 The middle arrows indicate the directions in which the auxiliary information display lamps 200 are sequentially illuminated.

[0074] Furthermore, when two or more conditions are met simultaneously among the multiple patterns, the control device 700 displays the sixth pattern with the highest priority on the auxiliary information display lamp 200, and can display the first pattern and the second pattern with higher priority than the third pattern and the fifth pattern. In addition, since the fourth pattern indicates the operation standby state, it is difficult to overlap with other patterns, but if it overlaps, it is ranked at the back.

[0075] On the other hand, if the construction machine 101 does not sense a brake signal while traveling in the traveling mode, the auxiliary information display light 200 may be in an off state. That is, the auxiliary information display light 200 may be turned off.

[0076] Refer to the following Fig. 9 The control method of the construction machine 101 according to the first embodiment of the present invention will be described. That is, the control and operation method of the auxiliary information display lamp 200 used in the construction machine 101 will be described as an example. At this time, the construction machine 101 may be a wheeled type.

[0077] like Fig. 9 As shown, when the construction machine 101 starts to move, it is determined whether it is currently in the travel mode or the work mode.

[0078] First, when it is determined to be the driving mode, a brake signal is sensed, and when the brake signal is sensed, the sixth pattern is displayed by the auxiliary information display lamp 200. On the contrary, when the brake signal is not sensed, the auxiliary information display lamp 200 is in an off state.

[0079] In this way, when the construction machine 101 operates in the travel mode, the auxiliary information display lamp 200 performs the function of an auxiliary brake lamp.

[0080] Next, when it is determined that the operation mode is in operation mode, it is determined whether the construction machine 101 is currently in operation standby.

[0081] When it is sensed that the operation is on standby, the auxiliary information display lamp 200 displays a fourth pattern.

[0082] When the machine is not in operation standby, it is prioritized to sense whether the machine is in swing operation.

[0083] When the rotation is in progress, the rotation direction is sensed. If it is a clockwise rotation, the auxiliary information display light 200 displays a first pattern; if it is a counterclockwise rotation, the auxiliary information display light 200 displays a second pattern.

[0084] When the turning action is not in progress, it is determined whether an object is sensed during the backward movement of the construction machine 101. When an object is sensed during the backward movement, the auxiliary information display lamp 200 displays a fifth pattern.

[0085] Finally, the working device 150 senses the motion of the boom cylinder, the arm cylinder, the bucket cylinder, or the optional cylinder. When the motion of the working device 150 is sensed, the auxiliary information display lamp 200 displays a third pattern.

[0086] In addition, when the operation of the working device 150 is not sensed, the process of determining whether the working device 150 is in the working standby state is repeated again.

[0087] That is, when the construction machine 101 is operating in the working mode, the auxiliary information display lamp 200 displays various patterns, thereby informing and warning the operator working nearby of the type of work performed by the construction machine 101 to draw his attention.

[0088] Through this configuration, the engineering machine 101 according to the first embodiment of the present invention can auxiliary display the current status to the surroundings through the multifunctional auxiliary information display light 200 to effectively give warnings.

[0089] Refer to the following Fig.10 and Fig.11 A second embodiment of the present invention will be described.

[0090] like Fig.10 As shown, the traveling body 122 of the construction machine 102 may be a crawler type. That is, the construction machine 102 can move during operation due to its crawler type characteristics, but will not operate in a traveling mode for traveling.

[0091] Therefore, the construction machine 102 of the first embodiment of the present invention can omit the operation travel determination unit 310 and the brake signal sensing unit 360 included in the first embodiment described above.

[0092] Furthermore, among the plurality of patterns, the sixth pattern implemented when a brake signal is sensed during traveling of the traveling body 122 or during operation standby of the working device 150 may be omitted. That is, the auxiliary information display lamp 200 does not function as an auxiliary brake lamp.

[0093] Furthermore, since the sixth pattern is omitted from the plurality of patterns, the control device 700 may display the first pattern and the second pattern on the auxiliary information display lamp 200 with the highest priority.

[0094] As described above, the construction machine 102 of the second embodiment of the present invention is the same as the first embodiment except that the operation travel determination unit 310 and the brake signal sensing unit 360 are omitted, and the sixth pattern among the plurality of patterns is omitted.

[0095] Refer to the following Fig.11A control method of the construction machine 102 according to the second embodiment of the present invention will be described. That is, a control and operation method of the auxiliary information display lamp 200 used in the construction machine 102 will be described as an example. In this case, the construction machine 102 may be a crawler type.

[0096] like Fig.11 As shown, when the construction machine 102 starts to operate, the construction machine 102 determines whether it is currently in operation standby.

[0097] When it is sensed that the operation is on standby, the auxiliary information display lamp 200 displays a fourth pattern.

[0098] When the operation is not in standby mode, priority is given to sensing whether the rotation operation is in progress.

[0099] When the rotation is in progress, the rotation direction is sensed. If it is a clockwise rotation, the auxiliary information display light 200 displays a first pattern; if it is a counterclockwise rotation, the auxiliary information display light 200 displays a second pattern.

[0100] When the turning action is not in progress, it is determined whether the construction machine 102 senses an object during the backward movement. When the construction machine 102 senses an object during the backward movement, the auxiliary information display lamp 200 displays a fifth pattern.

[0101] Finally, the working device 150 senses the motion of the boom cylinder, the arm cylinder, the bucket cylinder, or the optional cylinder. When the motion of the working device 150 is sensed, the auxiliary information display lamp 200 displays a third pattern.

[0102] In addition, when the operation of the working device 150 is not sensed, the process of determining whether the working device 150 is in the working standby state is repeated again.
