Description

  The present invention relates to an endless track type vehicle cleaning apparatus that is mainly used for spraying cleaning water on an endless track portion of an endless track type vehicle and cleaning and removing adhering mud.

  A vehicle having an endless track portion (for example, a construction machine such as a shovel car or a bulldozer) is a work in a poor scaffold, and therefore a lot of mud adheres to the endless track portion after the work. The adhering mud is dried or frozen as time passes and adheres to the endless track, so that the operator has required a great deal of labor and time to remove the adhering mud. In view of this, an endless track type vehicle washing apparatus as disclosed in Patent Document 1 has been proposed. This device comprises a main body that runs along the side surface of the endless track vehicle, a support that is supported by the main body so as to be movable up and down, and a swinging nozzle that is provided on the support. The swing nozzle is operated and high-pressure cleaning water is sprayed so as to draw a waveform trajectory, and the endless track portion is cleaned while changing the lifting position of the support. In addition, the cleaning apparatus is provided with a model selection switch for selecting the type of vehicle to be cleaned, so that a cleaning pattern corresponding to the model can be selected.

By the way, with the diversification of endless track type vehicles in recent years, the types of endless track portions to be cleaned are increasing, and it is not possible to cope with the selection of model alone. In addition, it is not preferable to set a cleaning pattern suitable for all the endless track portions in advance because it increases the storage capacity and complicates the operation.
Japanese Patent No. 2583156

  The problem to be solved by the present invention is to provide a cleaning apparatus capable of arbitrarily setting a cleaning pattern in accordance with the shape of the endless track portion to be cleaned.

In order to solve such problems, the present invention provides a guide rail disposed along a side surface of an endless track type vehicle, a carriage that travels on the guide rail, a nozzle device that moves up and down on the carriage, A cleaning device comprising a pump for supplying cleaning water to the nozzle device, and cleaning the endless track type vehicle with the cleaning water sprayed from the nozzle device. storage means in which a pattern is stored, the remote control device for arbitrarily adjusting the operation contents of the cart and the nozzle device while executing the stored cleaning pattern in said storage means, based on the cleaning pattern adjusted by the remote control device And a control means for controlling the carriage and the nozzle device.

  According to the present invention, the model of the endless track type vehicle to be cleaned is selected, and the initial setting of the cleaning pattern can be arbitrarily changed. Cleaning corresponding to the model can be executed. If the initial setting is changed, the operation contents of the carriage and nozzle device in the cleaning pattern are displayed as numerical data and image data, and if the data is increased or decreased, it is sensibly desired to extend the traveling range of the 20 cm carriage. Setting change can be easily executed. In addition, if the operation content of the carriage or nozzle device is edited by an external editing device and sent to the main body via a portable storage medium, the manufacturer can create a cleaning pattern that suits the user without going to the site. Appropriate response becomes possible. Furthermore, a more realistic cleaning pattern can be obtained by adjusting the position of the carriage or nozzle device while actually cleaning and storing the cleaning operation.

Next, the operation of the endless track type vehicle washing apparatus according to the first embodiment will be described.
The worker stops the washing vehicle C at a predetermined position in the car wash space A, and operates the operation panel 44 to execute the car wash program. As the procedure, first, the model selection key 45 is input, the desired model is displayed while the display on the display panel 54 is switched by operating the feed / return key 47, and then the enter key 50 is input. Next, the vehicle dirt degree key 46 is input, and the feed / return key 47 is operated to display the desired number of washings while switching the display on the display panel 54, and then the enter key 50 is input. If operation so far is performed, the pumps 29 and 32 will operate | move and washing water will be injected from the nozzles 20 and 21. FIG. The operator operates the traveling position of the carriage 3 and the swing position of the nozzle device 4 using the positioning key 49 while looking at the place where the washing water is hit, and the washing start position determined according to the vehicle to be washed. Move so that the washing water hits.

  The positioning of the nozzle is intended to prevent a difference from occurring in the portion where the cleaning water hits depending on the stop position or model of the vehicle. Since the carriage 3 is waiting in the initial state at the rear end position of travel detected by the travel limit 6a, the lower end position of lift / lower limit detected by the lift limit 17a, and the swinging downward position detected by the amplitude limit 24a, the positioning key 49 is used. Adjust the running position and the swing position, and set the cleaning start position according to the stopped vehicle. When the enter key 50 is entered after the desired position is set, the setting becomes valid. By entering the start key 51, the car wash operation is executed from the set wash start position according to the decided program.

  FIG. 7 is a flowchart showing a cleaning program executed when the model to be cleaned is set to “hydraulic excavator” and the degree of contamination is set to “level 1 (low)”, and FIGS. 8 to 11 show the cleaning program executed. It is the conceptual diagram which showed the cleaning locus | trajectory of the nozzle in case, and cleaning operation | movement is demonstrated using these figures.

  When the cleaning starts, the first cleaning pattern is executed by moving the nozzle body 22 in the vertical direction while changing the traveling position of the carriage 3 and cutting off the mud stuck to the endless track portion of the vehicle (1). The first cleaning pattern draws a cleaning trajectory as shown in FIG. 8 and applies cleaning water to the endless track portion. The cleaning start position P1 positioned before the start (running position: arbitrary, elevating position: lower end, neck) The operation is started based on the swing position (arbitrary), and first, the lift motor 15 is driven to move the nozzle device 4 up and down between the predetermined height position h1 and the cleaning start position P1 (arrow a). Thereafter, the traveling motor 12 is driven to move the carriage 3 forward by a distance s1 (arrow b), and the nozzle device 4 is moved up and down again at that position. Thus, the nozzle device 4 is alternately moved up and down the height h1 and the carriage 3 is moved forward by the distance s1. When the nozzle apparatus 4 is repeated n1 times (here, 20 times), the advancement of the carriage 3 is stopped. Subsequently, in the same procedure, the nozzle device 4 is moved up and down the height h1-the carriage 3 is moved backward by the distance s1, and the carriage backward movement is stopped when it is repeated n1 times. The comb-shaped cleaning trajectory obtained by such a first cleaning pattern is effective for cutting mud adhering to the upper part of the endless track portion, and the injection of high-pressure cleaning water in the vertical direction as the nozzle is raised and lowered is the same. By acting back and forth on the trajectory, the hardened mud is reliably destroyed. The destroyed mud is gently washed away by a low-pressure jet with a large flow rate and peeled off from the endless track.

  Next, by moving the carriage in the front-rear direction while changing the raising / lowering position of the nozzle body 22, a second cleaning pattern for washing away the mud removed by the first cleaning pattern is executed (2). The second cleaning pattern draws a cleaning trajectory as shown in FIG. 9 and applies cleaning water to the endless track portion, and is based on position P2 (running position: front end, lift position: lower end, swing position: upward). The operation is started and the traveling motor 12 is driven to reciprocate the carriage 3 to the distance s2 (arrow c). Thereafter, the lift motor 15 is driven to raise the carriage 3 by a predetermined height h2 (arrow d), and the carriage 3 is made to reciprocate again at that height position. Thus, the height position of the nozzle device 4 is changed and the carriage 3 is reciprocated n2 times (here, 3 times). By such a second cleaning pattern, the mud that could not be removed by the first cleaning pattern is completely stripped off by the high-pressure cleaning water jet in the horizontal direction. Then, it is further softened and peeled off from the endless track portion by the large-flow low-pressure injection.

  Next, a third cleaning pattern for cleaning the upper surface of the endless track portion is executed by adjusting the swing angle of the nozzle body 22 and moving the carriage 3 in the front-rear direction (3). The third cleaning pattern draws a cleaning trajectory as shown in FIG. 10 and applies cleaning water to the upper surface of the endless track portion. The position P3 (running position: front end, elevating position: upper end, swinging position: downward position) From the base point), the travel motor 12 is driven to reciprocate the carriage 3 to the distance s3 (arrow e), and then the lift motor 15 is driven to start the carriage 3. Is lowered by a predetermined height h3 (arrow f), and the carriage is reciprocated again at that height position. Thus, the height position of the nozzle device 4 is changed and the carriage 3 is reciprocated n3 times (here, 4 times). By such a third cleaning pattern, the mud stuck to the upper surface of the endless track portion is cleaned.

  Next, a fourth cleaning pattern for cleaning the inner bottom surface of the endless track portion is executed by moving the carriage 3 in the front-rear direction while changing the nozzle swing angle (4). The fourth cleaning pattern draws a cleaning trajectory as shown in FIG. 11 and applies cleaning water to the inner bottom surface of the endless track portion. The position P4 (travel position: front end, elevating position: lower end, swing position: upward) Operation is started from the position), the swing motor 23 is driven to swing the nozzle body 22 downward by a predetermined angle r2 (arrow g), and the travel motor 12 is driven to move the carriage 3 to the distance s4. Reciprocate (arrow h). Thereafter, every time the swing motor 23 is driven to swing the nozzle body 22 downward by a predetermined angle r2, the carriage 3 is reciprocated, and the carriage 3 is moved n4 times (in this case, three times) by changing the nozzle swing angle. ) Make a round trip. By such a 4th washing | cleaning pattern, the mud stuck to the inner bottom face of an endless track part is wash | cleaned.

  Thus, when the first to fourth cleaning patterns are executed, the cleaning program for the hydraulic excavator is completed. The cleaning water sprayed in this apparatus is, for example, about 300 liters / minute and 0.3 MPa from the low pressure large flow rate nozzle, and 10 liters / minute and 20 MPa from the high pressure low flow rate nozzle. Even if it is very firmly fixed like frozen soil due to different types of washing water jets, it can be surely dropped by washing form that cuts into blocks by high pressure and at the same time drops blocks cut by large flow rate. be able to.

  The travel distances s1 to s4 in the bogie travel operation and the swing angles r1 and r2 in the nozzle swing operation are detected by the travel encoder 13 and the swing encoder 25, respectively, and the predetermined heights h1 to h1 of the nozzle device in the nozzle lift operation are detected. h3 is determined by the energization time of the lifting motor 15. This is to cope with the type of vehicle to be cleaned, mainly the length and height of the endless track portion.

  The setting values of each cleaning pattern in such a cleaning program are stored in advance for each model that can be selected by the model selection key 45. In the present invention, these initial setting values can be changed. Is possible. The procedure for changing the setting will be described below with reference to FIG. The setting change in the first embodiment is performed by an operation on the operation panel 44.

  When the key switch 51 is used to switch to the management mode, the display panel 54 is fully lit. When the model selection key 45 is input here, the first cleaning program “PC-60” is displayed. After using the feed / return key 47 to match the cleaning program to be changed, the enter key 50 is input. Then, the display panel 54 is switched to the setting change display. Here, since the travel distance s1 of the first cleaning pattern is first displayed on the display panel 54 together with the initial set value, the numerical value is arbitrarily set (0 to 99) with the feed / return key 47 and the enter key 50 is input. . Subsequently, since the elevation height h1 of the first cleaning pattern is displayed on the display panel together with the initial setting value, the numerical value is arbitrarily set (0 to 99) with the feed / return key 47 and the enter key 50 is input. Next, since the number of times of raising / lowering n1 of the first cleaning pattern is displayed on the display panel 54 together with the initial set value, a numerical value is arbitrarily set (0 to 99) with the send / return key 47 and the enter key 50 is input.

  Thereafter, each time the feed / return key 47 is input, the travel distance s2 / lifting height h2 of the second cleaning pattern, the travel distance s3 of the third cleaning process, the swing angle r1, the lifting height h3, the fourth cleaning process. Are displayed on the display panel 54 in the order of the travel distance s4 and the swing angle r2, and the initial setting can be changed in the same procedure. If the start key 51 is input when any item is changed, the setting value changed so far is rewritten with the initial setting value, and the display panel 54 returns to the display of the changed cleaning program.

In this way, a cleaning operation that cannot be handled by model selection alone can be rewritten to a cleaning program suitable for the purpose of use by allowing the user to arbitrarily change the set value.
In addition, the display panel is a multi-function monitor that can display multiple information, and it is possible to change the initial setting value by outputting the cleaning process name and change item name, or display the operation of the carriage and nozzle device as an image. You may enable it to correct | amend the position of a trolley | bogie or a nozzle apparatus, reproducing the washing | cleaning operation | movement along an initial setting value.

Next, another setting change procedure will be described with reference to FIG. The setting change in the second embodiment is performed using an external editing apparatus such as a PC (personal computer).
In the cleaning device of the second embodiment, a reader device 61 that receives a card or a stick-type portable storage medium 63 is added to the operation panel 60 in addition to the device of the first embodiment. The external editing device 62 finely sets a cleaning pattern that meets the user's needs, and the cleaning pattern is stored in the storage medium 63 and read by the reader device 61 on the main body side. In the control unit on the main body side, the cleaning program stored in the memory is rewritten to the cleaning program read by the reader device 61.

Next, another setting change procedure will be described with reference to FIG. The setting change in the third embodiment is performed using a remote operation device such as a remote controller.
In the cleaning device of the third embodiment, a remote operation device 71 capable of performing operations such as cleaning reception at a position away from the operation panel 70 is added to the device of the first embodiment. The remote control device 71 has a function of arbitrarily setting the movement range of the carriage and the nozzle device, in addition to receiving normal cleaning. When arbitrarily setting, regardless of the model or the like, the first cleaning pattern to the fourth cleaning pattern are executed in order, and the user specifies the range and degree to be cleaned. At this time, the operations of the carriage and the nozzle device in each cleaning pattern are reproduced so as to run and ascend and descend between the limits, and a determination key is input at a position where it is desired to stop.

  It is possible to provide a cleaning apparatus capable of registering an original cleaning program corresponding to an endless track type vehicle having a high cleaning frequency at an installation location or an installation store.
