The operating device uses a swivel arm, and the swivel arm mainly uses water. can be pivoted across the upper limit of said element in a flat plane, and at one end thereof can be pivoted on one of the boundary side elements.

One example of such a work platform is a lever that raises and lowers the basket. - refers to the work basket located at the free end of the device. Such equipment, for example For example, it is used to de-ice an aircraft just before take-off.

In these cases, the lever device is usually installed on the moving frame and The frame also supports the de-icing system with the vessel, pump and associated valves. where one or more mediums are guided through a bath with a spray nozzle m1fc. This system leads to the ket. To de-ice an aircraft; The system is guided to the aircraft, the basket is raised to the correct working height, and then the aircraft The second spray is carried out from the basket by manual operation of the nozzle. Spraying is good preferably within just a few minutes and partially within narrow limits, the consumption time included but, in particular, also reduces the temperature loss of the atomized liquid.

U.S. Pat. No. 3,439,372 discloses an aircraft cleaning device. Washing is Controlled from an open work basket. Pivotally suspended about a vertical axis within the working ring. In front of the suspended basket, a cleaning block is placed by a boom that pivots around a horizontal axis. Rashi is installed. This boom contains other rotating links. Overall rotation The positioning is controlled remotely from the work basket. Manual operation of the swivel arm supporting the nozzle There are no vertical problems.

U.S. Pat. No. 3,460,177 discloses a closed cabin for remotely controlling cleaning operations. Discloses an aircraft cleaning system comprising: The cleaning brush is a movable rod. located on the assembly. Problems with manual control of the swivel arm supporting the nozzle does not exist.

U.S. Pat. No. 4,334,649 discloses a spraying method for non-circular spraying of a coating layer onto a workpiece. Discloses the fog nozzle Susvenge Aoi. The arm problem does not exist and its different The links are movable with respect to each other, but manual control of the arm system! ；Meno processing There is no question of a particular form of arm with respect to objects.

U.S. Pat. a working basket, where the working basket is designed to support the weight of the nozzle; should be used to cut off forces affecting the nozzle during work. The nozzle is a basket attached to the center of one side wall of the machine and located on the arm. , the arm is capable of pivoting about a vertical axis on a horizontal plane. on a vertical plane , the nozzle can pivot around a horizontal axis. These two axes are the arm's meet each other on a common vibrating bed. of the rotation of the nozzle with respect to the arm There are no beds for them.

U.S. Pat. No. 3,010,533 has two nozzles protruding from its front side. Disclosing working cabin. Each nozzle is suspended by a swivel and It has an operating hand grip. The media supply conduit runs along the side of the cabin; and with respect to the cabin, i.e. with respect to the operator's workpiece l; with respect to the horizontal plane It doesn't seem to rotate on top.

U.S. Pat. No. 3,064,754 also includes a work basket. The mower assembly can be heated to prevent ice formation. the nozzle There is no special pivot arm to move with respect to the basket.

The aim of the invention is to accomplish the task of spraying in a safe, quick and comfortable manner. The objective is to provide an operating device that makes it possible.

According to the invention, this object is achieved by providing that the swivel arm has a concave angle in the horizontal plane; The length of the swivel arm must be be larger than the cross-sectional dimensions of the platform, and also have an angular shape. The arm has at its other end a pivot bed for the reservoir of the spray nozzle; The bed is connected with an operating hand grip that protrudes in the direction along the swivel arm. This is achieved by the fact that there is.

Now, from the work basket with the swiveling arm supporting the nozzle open, the operator The swivel arm on a horizontal surface without the need for manual operation to reach large work areas A possible operating device is provided that makes it possible to do so.

because the operator's position in the basket is in that direction . The concave angled shape allows the top nozzle-supporting end of the swivel arm to It is possible for the operator to turn past the motor with further lateral movement. The motor must stand partly between the bounding side elements and partly between the swivel arms. Near the side of the work platform where the swivel arm is Can be rotated by law.

The invention will be explained in more detail below with reference to the accompanying drawings.

FIG. 1 schematically shows a vehicle with a link rod arrangement and a working platform; Here the working platform is mounted on the carriage and surrounded by boundary side elements. It is in the form of

FIG. 2 shows one of the five baskets with an embodiment of the operating device according to the invention. 1! FIG. 2 shows an enlarged perspective view of the embodiment.

Figure 3 schematically shows the different positions of the operator in the basket, viewed from above. to show.

FIG. 1 shows a vehicle in the form of a truck supporting a carrot housing 2, where Containers, pumps and associated valves are arranged in the container. on the roof of the housing , supporting a link rod 4 that can be pivoted up and down by a hydraulic piston 5; A parallel arm mechanism 3 is arranged. The rotary table 6 allows the link rod 4 to be rotated at its upper end. It is connected to other link rods 7 at. The link rod 7 is connected by a hydraulic piston 8. The rotary table 6 can also rotate on a horizontal plane. can. At its outer end, this link rod has a working platform in the form of a basket 9. Support Home.

As shown in Figure 2, the bottom platform of the basket is , surrounded by side wall elements 10, 11 and 12. in the center of the edge of wall element 12 In this case, the supply conduit 13 for the deicing medium from the engine housing 2 is connected to the basket. ends at the bottom of the cut. Due to the swivel 14, the conduit 13 is connected to the tubular pivot arm 15 The entirety is indicated by 15. The arm consists of an upper part 16, The part is pivoted along the center of the wall element 12 by two support beds 17. has been done. The horizontal portion 18 of the pivot arm 15 has a concave angular shape; And support swivel 19 at its free f41m, and on that swivel 1; A spray nozzle 20 is attached. Figure 3 has two opposing angles. shape, one at the suspended end of the swivel arm and the other at the free end of the arm exist. The nozzle 20 is connected to an operating hand grip 21 and The grip protrudes along the direction of the section 18 of the pivot arm.

During the spraying operation, the rebound pressure of the atomized medium from the nozzle to the pivoting arm 15 The signal is then transmitted to the arm anchor by the basket 9. As shown in Figure 3, The operator can concentrate on manual control of the desired distribution of the liquid being sprayed; Ru. As can be seen from the same drawing, the concave angle of the section 18 of the pivot arm 15 is also Due to its shape, the operator can move at least The direction of the spray can be controlled across a 180° arc. In Figure 3 In all three typical work positions labeled A%B and C. The rebound pressure from the spray is reduced by the operator as a result of the angular shape of the pivot arm. It is guided past the motor to the support bed 17. At outer positions A and C, the position The arm with the angled portion 18 at A is located outside the basket wall. The swivel arm allows the operator to unimpeded the basket wall. For the same reason, the arm can always approach the bus in position C. A certain distance remains from the basket wall 12, and the operator thus part 8 of the pivoting arm and at the same time the nozzle 20 is actually basket! ! 12 extensions. In this way, the operator The operator has complete control over the nozzle 20 in all possible positions that occur during the actual job. and at the same time change the 9L fog position easily and quickly. Can be done. The angle is defined as the movement of the swivel arm and the movement of the nozzle suspension. In combination with gender, it is possible to actually reach a 360-degree simultaneous workplace. and thus, for example, the tail as well as the wings of an aircraft from a single location on the vehicle. can perform the following tasks. Small changes in spray direction can be achieved by swivel 19 alone. However, a larger change would be to change the pivot arm 15 as shown in FIG. It can be easily implemented by pivoting to another starting position.

The present invention is described above with respect to a system for deicing an aircraft. However, the book The invention is not limited to its field of application, but can also be used for other spraying tasks, especially for larger surfaces. Can be used for jobs that require rapid spraying.
