Description

Lighting car {Floodlight car}

The present invention relates to an illumination vehicle in which the lighting device is moved up and down by hydraulic pressure in a container for use in special situations such as night demonstrations or for night work lighting such as rescue, search, search, construction, and the like.

Conventional lighting means that are conventionally used for night work such as workplace lighting in any place include Japanese Patent Application Laid-open No. Hei 9-39644 and Japanese Patent Application Laid-open No. Hei 9-306226. This invention is a type of high ladder ladder with a boom that can be operated in a multi-stage hung at the end of the plural lamps are arranged in a row horizontally arranged by the winch while adjusting the length and direction of the boom.

There is a lighting vehicle dedicated to lighting that can move away from such temporary lighting means to any place, Japanese Patent Application Laid-Open No. 13-67926 (published on March 16, 2001). The present invention is configured in the telescopic method of the support (multiple) luminaires to be fixed by raising or lowering the support while tightening or loosening the knob by hand, the support between the winding drum is installed It is fixed so that the wire connected to the luminaire is released from the winding drum when the support is lifted up, and the operation section is installed on the mobile trolley with a plurality of wheels so that it can be moved to an area requiring night work.

However, the above light vehicles and lighting means are purely for use in night work for construction, so the conventional prior art is not only possible to move remotely, but also as a means for illuminating protesters at night demonstrations. none.

Under special circumstances, such as night demonstrations, lighting devices as a means of dissolving and dissolving the protesters' views, in some cases, need to be focused on at least 4,000W in one direction. In addition, since the protesting crowd moves from place to place while moving, the lighting device must be free to change directions at least. In some cases, a means of concealing the lighting device is needed because the stone or Molotov can be thrown toward the demonstrators.

In view of these considerations, several lamps are placed in one case, and a rack-shaped support is installed at the bottom of the case, and the lifting and lowering of the support is pushed up or down by the pinion operated by the driving force of the motor. I applied it. However, at this time, the lamp case is heavy and the motor is overloaded so that a failure occurs between the motor and the pinion, and the speed of raising the support is too slow to take 3 to 4 minutes to raise completely. In addition, it is not possible to increase the height of the lamp case can not only illuminate a large area, but also the lamp case is not rotated, there was a problem that can only be illuminated in one direction.

The purpose of the present invention is not only for night work lighting such as rescue, search, search, construction, etc., but also for intensive lighting for demonstrators under special circumstances such as night demonstrations, and the direction can be changed to suit the properties of protest crowds moving from place to place. The present invention provides an illumination vehicle having an illumination device that can be quickly concealed from a stone or a molotov cocktail.

The present invention is to rotate the luminaire up and down by the operating force of the luminaire having a plurality of lamps disposed in the case, and the hydraulic cylinder is fixed to the lower end of the case axially installed on both sides of the bracket in order to achieve the above object Up and down rotation mechanism to rotate, the left and right rotation mechanism to rotate left and right about the center pivot by the driving force of the motor at the bottom of the bracket, and the operating force of the hydraulic cylinder installed in the upper open container and the lower side of the left and right rotation mechanism An elevating mechanism for simultaneously elevating the luminaire, the up and down rotating mechanism, and the left and right rotating mechanism into and out of the container; and a hydraulic tank for supplying hydraulic pressure to the hydraulic cylinders of the up and down rotating mechanism and the elevating mechanism, respectively. A generator for supplying power to the lamp and the motor, and the generator and the hydraulic tank. It is constituted by the output line, and a controller for controlling the lamp.

The elevating mechanism may use a cash register method and a multi-stage cylinder (or telescopic) method. In the case of the register type, a four-section link type in which two links cross each other in an X-shape can be used. Can be used. In the case of the trash can, the link should be installed symmetrically on both sides of the lower part of the left and right rotating mechanisms and be lifted at the same time by the hydraulic cylinder. In the case of the multi-stage cylinder system, two to three hydraulic cylinders, preferably two multistage hydraulic cylinders, may be provided on both sides of the lower part of the left and right rotating mechanisms and lifted by hydraulic pressure.

In the ceiling of the container, a case with a lamp must be opened to move up and down the container by a lifting mechanism. In this open space, when the cable is pulled by the driving force of the motor, it can be opened and closed along the left and right rails. It is desirable to install a door. In case of installing door, opening and closing is to be controlled by controller. At this time, when the lift operation signal of the lifting mechanism is given, the controller should automatically drive the motor to open the door.

The present invention, according to the configuration as described above, the lamp is turned on by the controller or operate the hydraulic cylinder. When the hydraulic cylinder of the vertical rotating mechanism is operated, the hydraulic cylinder pushes the lower end of the case forward or pulls back, so that the case rotates about the horizontal axis on both sides, and the optical axis of the lamp is rotated up and down. When the motor is operated, the left and right rotating mechanism rotates left and right about the pivot, so the optical axis of the lamp rotates left and right. When the hydraulic cylinder of the lifting mechanism is operated, the lifting mechanism moves up and down, so the optical axis of the lamp moves in the vertical direction.

Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings. First, an embodiment will be described with reference to FIGS. 1 to 8. Particularly, in one embodiment, the elevating device uses a six-section link in which two links cross each other in an X shape and is connected in two pairs. In another embodiment described later (FIG. 9), four links in which two links cross each other in an X shape are described. Section link was used. However, the multi-stage cylinder lifting device is relatively simple in structure and can be implemented even in the above description.

The luminaire is a plurality of lamps 2 arranged uniformly in the horizontal and vertical directions on the front of the case 1 formed in a rectangular cylindrical shape. Lamp 2 is a beam light, the number required varies depending on the use, but when used for demonstration suppression, it is desirable to arrange 12 1KW each in two rows, so that the power consumption is about 12KW. Of course, you can make changes such as adding more depending on the situation. Both sides of the case 1 are provided with horizontal axes 3 which form a rotation axis when the case 1 is rotated up and down.

The up-and-down rotation mechanism is comprised with the bracket 4, the auxiliary bracket 5, and the hydraulic cylinder 6. As shown in FIG. The bracket 4 forms a U-shaped cross section when viewed from the front and surrounds both sides and the bottom of the case 1 in a state spaced apart from the case 1 by a predetermined distance. At both ends of the bracket 4, the transverse shaft 3 is rotatably fixed together with the bearing 7. The auxiliary bracket 5 is a lateral L-shaped cross section welded to the rear of the bracket 4, and one end of the hydraulic cylinder 6 is fixed to the upper end of the auxiliary bracket 5. An auxiliary rod 9 is connected to the rod 8 of the hydraulic cylinder 6 so that articulation is possible, and an end of the auxiliary rod 9 is connected to the lower end of the case 1 by a hinge 10. Therefore, when the hydraulic cylinder 6 is operated, the case 1 rotates up and down about the horizontal axis 3 of both sides. That is, when viewed from the side, the case 1 rotates clockwise or counterclockwise.

The left and right rotating mechanism is composed of a rotating ring 11, the frame 12 and the motor (13). The rotary ring 11 is a circular pipe is bent into a circular ring shape and then the outer circumferential surface is processed into a semicircular cross section, and the connecting pipe 14 is welded crosswise in the middle. The top of the rotary ring 11 is fixed to the bottom of the bracket (4). Eight rollers 15 are fitted in the circumferential direction of the rotary ring 11 in the semicircular cross section formed on the outer circumferential surface of the rotary ring 11. Roller 15 is fixed to the frame 12, the roller 15 is inclined diagonally toward the outer surface of the rotary ring (11). The roller 15 supports the rotation ring 11 rotatably in a state in which the rotation ring 11 floats in the air. Pulley 16 is fixed to the center of the bottom surface of the rotary ring 11 is connected to the motor 13 and the belt 17 of one side of the frame 12. Rotating the motor 13 rotates the rotary ring 11 left and right. If a limit switch is attached to one side of the frame 12 and a stopper is attached to the rotary ring 11, the rotation range may be restricted.

The lifting mechanism is composed of an upper rail 18, a lower rail 19, four links 20a, 20b, 20c, and 20d, and a hydraulic cylinder 21. Two upper rails 18 are fixed in parallel to both sides of the frame 12, and two lower rails 19 are fixed in parallel on the support 23 of the container 22. On one side of the upper rail 18 and the lower rail 19, rollers 24a and 24b installed at one free end of the links 20c and 20d are fitted to form roller grooves 25a and 25b which can slide left and right. It is. The four links 20a, 20b, 20c, and 20d are connected in the form of a ledge that crosses up and down twice in an X-shape. The X-shaped intersecting part and the ends of the links 20a, 20b, 20c, and 20d are connected by hinges, and two sets of left and right are symmetrically formed so that the links 20a, 20b, 20c, and 20d on both sides are auxiliary supports. (26) leads to a balance. As shown in FIG. 4, the end of the link 20a extending to the upper left and the end of the link 20b extending to the lower left are respectively fixed to the upper rail 18 and the lower rail 19, and the link 20c extending to the upper right. ) And the ends of the link (20d) extending down the right side is provided with rollers (24a, 24b) to slide left and right along the rail grooves (25a, 25b) of the upper rail (18) and the lower rail (19). . A hydraulic cylinder 21 is provided between the lower middle of the link 20a extending to the left side and the left end of the lower rail 19 so as to allow joint motion. Thus, when the hydraulic cylinder 19 is operated upward, four links 20a, 20b, 20c, and 20d are raised as shown in FIG. 4 to raise the case 1, and when the hydraulic cylinder 21 is operated downward, as shown in FIG. It will be folded down like an imaginary line.

The roof of the container 22 is open so that the case 1 can be lifted up and down, and a driving force of a motor (not shown) is raised thereon in response to a signal from the controller 27 when the links 20a, 20b, 20c, and 20d are raised. Although the door 28 which can be opened while sliding to the rear by the door is installed, this is not applied in some cases, so the description thereof will be omitted since it is not a right in the present invention. If, by design, the door 28 is applied, the cable may be opened and closed while sliding forward and backward along the left and right rails when the cable is pulled by the driving force of the motor. Then, the door 28 may be opened by the signal of the controller 27 when the lift operation signal of the hydraulic cylinder 21 is given.

The hydraulic tank 29 includes a hydraulic pump and is installed inside the container 22. The hydraulic tank 29 has a hydraulic line connected to the hydraulic cylinder 6 installed on the auxiliary bracket 5 and the hydraulic cylinder 21 provided on the links 20a to 20d, respectively, and the two-way valve 30, 31) is installed. The two bidirectional valves 30 and 31 are opened and closed according to the operation signal of the controller 27.

The generator 32 is installed inside the container 22 and supplies power to the hydraulic tank 29, the lamp 2, and the motor 13 according to an operation signal of the controller 27. The controller 27 has an operation mode capable of outputting the generator 32, the lamp 2, the motor 13, and two bidirectional valves 30, 31. The operation mode includes a lighting mode for turning on the lamp 2, an off mode for turning off the lamp 2, an upward mode for turning the lamp 2 upward, a downward mode for rotating the lamp 2 downward, and a lamp 2 It consists of a leftward mode for turning left, a rightward mode for turning the lamp 2 to the right, an ascending mode for raising the lamp 2, and a descending mode for lowering the lamp 2.

The operation sequence of such an embodiment will be described. First, when the rising mode is selected in the controller 27, the hydraulic cylinder 21 is advanced by switching the bidirectional valve 31 to the rising port. Accordingly, as the links 20a, 20b, 20c, and 20d are developed, the case 1 is raised to raise the lamp 2 on the roof inside the container 22. When the links 20a, 20b, 20c, and 20d are deployed upward, the rollers 24a and 24b installed at the free ends of the links 20c and 20d are arranged along the roller grooves 25a and 25b and the upper rail 18 and the lower part. It slides toward the center of the rail 19. On the other hand, when the lowering mode is selected in the controller 27, the hydraulic cylinder 21 reverses by switching the bidirectional valve 31 to the lowering port. As a result, while the links 20a to 20d are folded as shown in FIG. 4, the case 1 descends and the lamp 2 enters into the container 22. When the links 20a to 20d are folded upward, the rollers 24a and 24b provided at the free ends of the links 20c and 20d are provided with the upper rail 18 and the lower rail 19 along the roller grooves 25a and 25b. Is sliding outwards.

When the lighting mode of the controller 27 is selected when the above rising mode is achieved, the lamp 2 is turned on. At this time, if the upward mode of the controller 27 is selected to upwardly adjust the optical axis, the hydraulic cylinder 6 is advanced by switching the bidirectional valve 30 to the upward port. Accordingly, the case 1 is rotated clockwise about the horizontal axis 3 in the state as shown in FIG. 6, so that the optical axis of the lamp 2 is upwardly adjusted. On the contrary, if the down mode of the controller 27 is selected to adjust the optical axis downward, the hydraulic cylinder 6 is reversed by switching the bidirectional valve 30 to the downward port, so that the case 1 has a horizontal axis 3 as shown in FIG. ), The optical axis of the lamp 2 is adjusted downward by rotating counterclockwise.

In addition, when the right direction mode of the controller 27 is selected to adjust the optical axis to the right, the power of the generator 32 is supplied to the motor 13 so that the motor 13 rotates forward and the rotating ring 11 rotates to the right. 1) and the optical axis of the lamp 2 are adjusted to the right. On the contrary, when the left mode of the controller 27 is selected to adjust the optical axis to the left, the power ring of the generator 32 is supplied to the motor 13 so that the motor 13 rotates in reverse and the rotating ring 11 rotates to the left. 1 and the optical axis of the lamp 2 are adjusted leftward. When the light-down mode of the controller 27 is selected when the lowering mode is achieved, the lamp 2 is turned off.

Figure 9 shows another embodiment of the lifting mechanism of the present invention. The lifting mechanism has two upper rails 181 fixed in parallel to both sides of the frame 12 and roller grooves 251a formed at one side thereof, and two upper rails 181 are fixed in parallel to the base 23 of the container 22 and fixed at one side thereof. The lower rail 191 formed with the roller groove 251b, and the two connected in the form of an X-shaped ledge, have rollers 241a and 241b installed at one free end of the upper rail 181 and the lower rail 191. A series of links 201a and 201b respectively fitted to the roller grooves 251a and 251b, and between the middle and the lower rail 191 of the link 201b and capable of elevating the links 201a and 201b. It consists of a hydraulic cylinder 211. The lift mechanism of this other embodiment differs from the lift mechanism of one embodiment in that it is connected in an X shape using only two links 201a and 201b. The rest is the same as in one embodiment. Therefore, since the operation of the other embodiment is basically the same as the embodiment, a description of the operation of the other embodiment is omitted.

Since the present invention is applied to a vehicle having a container, it is possible to focus on the protesters under special circumstances such as night demonstrations as well as night work lights such as rescue, search, search and construction. In addition, since the lamp can be rotated freely up, down, left, and right, it can be very useful for lighting for the crowd of protesters who move the place from time to time, especially when the place to be illuminated changes frequently. In addition, since the lamp can be adjusted to enter and exit the container, the lamp can be quickly concealed from the stones or molotov thrown by the demonstrators in case of emergency, thereby increasing the maneuverability while preventing damage to the equipment.
