[0003]

[Problems to be solved by the invention]

 This conventional balloon floodlight 50 emits light from the entire balloon floodlight 60 and illuminates a wide area, so that the work vehicle can be confirmed from a distance, and the large light source makes it difficult to cast shadows. Often used at night for road construction and construction sites. However, when this balloon floodlight device 50 is employed as it is at a track construction site, the following problems occur. At the track construction site, construction must be done within a short time at night when the railway does not run, and improving work efficiency is an important issue. The trolley with a balloon floodlight equipped with a generator is large and suitable for large-scale construction work, but is not suitable for general small-scale on-site work. Even when used on a construction site with a large track, it had to be placed near the track and relocated each time, requiring a lot of man-hours to move. Further, the single balloon floodlight is detachable and simple, but the tripod support member is lightweight, is insufficient against wind, and easily falls. When used alone in track construction, the wind measures to support the balloon are not sufficient, and the fixing of the tripod support member that supports the balloon floodlighting device must be further devised. In addition, the installed balloon floodlight device must be moved each time together with the separately installed generator, which also requires moving man-hours.

An object of the present invention is to provide a lightweight minecart for track construction in which a balloon floodlight can be attached and detached and a fall prevention function is provided.

[0005]

[0013]

[Embodiment of the invention]

 Hereinafter, the form of the minecart for the balloon floodlight device of the present invention will be described in detail with reference to the drawings.

FIGS. 1 to 4 show a first embodiment of a lightweight minecart for a balloon projector according to the present invention, and FIGS. 5 to 8 show a second embodiment. In the first embodiment, the lower part of the balloon floodlight is fixed to the bed of a minecart, and the upper part is detachably formed. In the second embodiment, the entire balloon floodlight device is formed detachably on the bed of a light truck, and the upper portion is formed detachably on the lower portion. FIG. 1 is an overall perspective view of a light truck for a balloon floodlight of the first embodiment. FIG. 2 is an overall side view of FIG. FIG. 3 shows a fixing structure of the support plate of the balloon floodlight as viewed from the back side. FIG. 4 is a cross-sectional view showing a structure for attaching the support device to the carrier. FIG. 5 is an overall perspective view of a light truck for a balloon light emitting device according to a second embodiment. FIG. 6 is a partial sectional view of the carrier stored in the receiving portion provided on the carrier. FIG. 7 is a partial sectional view of a carrier in which a tripod support member is fitted to the receiving portion of FIG. FIG. 8 is an overall perspective view showing a state in which the balloon projector and the generator according to the second embodiment are lowered from the carrier to the ground.

In the first embodiment, A is a light truck with a balloon light emitting device. The carrier 7 is made of a wooden board to reduce the weight, and the periphery of the carrier 7 is covered with a hard peripheral frame 6. A sub-frame is located on the lower surface of the carrier 7 and directly supports the carrier 7. The sub-frame includes a cross-shaped first sub-frame 4 and a second sub-frame 5. In this example, the first sub-frame 4 and the second sub-frame 5 are different in height (thickness). By providing the crossed subframes, the lightweight carrier 7 is prevented from being twisted, and the strength of the carrier 7 is maintained. Main frames 3a and 3b extending forward and backward are located below the subframes 4 and 5 on both sides of the loading platform 7. A hanging portion 26 is provided before and after the left and right main frames 3a, 3b, and a bearing 36 is fixed to a lower end thereof. The axle 9 having the bearing ring 33 integrally fixed to both ends thereof is rotatably mounted on the bearing 36. At the outer ends of the main frames 3a, 3b, operation rod support portions 29a, 29b are provided rotatably forward and backward. Similarly, they are provided on the left and right. On the outside of one side of the main frame 3a, there are provided a brake mechanism 20 for preventing rotation of the front and rear races 33, and a rod 23a as a connecting member for connecting the brake mechanism 20 and the operation rod supporting portions 29a and 29b. 23b, 23c and 23d are provided. The upper ends of the front, rear, left and right operation rod support portions 29a and 29b are opened so that both ends of the inverted U-shaped operation rod 28 can be fitted. The operation stick 28 is formed in an inverted U-shape, and its end is fitted to the left and right operation stick support portions 29a, 29a, so that the operation stick 28 can be operated at the center or the left and right sides. In addition, even if the operation rod support portion 29a is on both sides, only one brake mechanism is required. Normally, the bearing ring 33 has a structure in which a brake is applied. By manually pushing the operation rod 28 in the direction of the arrow, the brake is released and the truck can be moved. When the hand is released from the operating rod 28, the brake pad 21 presses against the tread surface 33a of the track ring 33 by the force of the spring 25, and the track ring 33 is braked. This adopts a structure that normally applies a brake to prevent the minecart from running on its own. The operation rod 28 can be replaced with front and rear operation rod support portions 29a and 29b. The operation rod 28 may be formed in a rod shape so as to be fitted to the operation rod support portion 29a on only one side. In this case, the operation rod support portions 29a and 29b may be provided before and after one side. In the figure, 22 is a driving member, 24 is a crank portion, and 27 is a support member. Further, hooks 30 are fixed by welding or the like at appropriate intervals around the entire periphery of the side surface of the loading platform 7 so as not to hinder the operation and movement of the balloon light emitting device 10. The hook 30 fixes the balloon projector 10 and the generator 31 and has a predetermined strength. The race 33 may be made of iron or hard resin. A detailed description of the brake mechanism 20 will be omitted.

At a crossed center of the first sub-frame 4 and the second sub-frame 5 of the bed 2, a cylindrical portion 13 for supporting the pole 12 a of the balloon floodlight 10 and a cylindrical portion 13 are fixed. A rectangular support plate 14 is provided. As shown in FIGS. 3 and 4, the support plate 14 is made up of a contact plate 8 for contacting the subframes 4 and 5 on the back side of the carrier 7 and a long bolt 18 and a nut 19 as fastening members. 14 is fixed to the bed 7. The fastening position between the support plate 14 and the contact plate 8 is made to be supported by the subframe in consideration of the durability of the carrier. The long bolt 18 and the nut 19 may be set upside down. On the poles supporting the balloon projector, one projection 12e is formed on one side so as not to rotate with respect to the other, and a hole 12f for fitting the projection 12e is formed on the other side. Similarly, a protrusion 12e and a hole 13f are formed in the lower pole 12a and the cylindrical portion 13. The fitting can be released by slightly turning the pole. The contact plate 8 that contacts the two sub-frames 4 and 5 in this example forms a slight step because the crossed sub-frames have different thicknesses. The end of the cylindrical portion 13 fixed to the support plate 14 by welding or the like is open in a cylindrical shape. However, since the periphery of the cylindrical portion 13 is fixed to the support plate 14, rainwater transmitted through the poles accumulates. Therefore, a drain hole 15 through which rainwater flows is formed in the support plate 14. The cylindrical portion 13 may have a bottom, but in this case, a drain hole is required in the bottom. A seat plate 16 is interposed between the support plate 14 and the loading platform 2 to form a space between the support plate 14 and the loading platform 2, and water dropped from the drain hole 15 flows on the loading platform 2 without stagnation. I will do it.

The balloon floodlight device 10 includes a substantially spherical balloon floodlight 11 having a built-in metal halide lamp therein, and a plurality of connectable poles 12 supporting the balloon floodlight 11. A plurality of hooks 37 fixed to the pole 12 are formed at a middle position of the pole 12. The rope 32 or the like as a fastening means is hooked over the hook portion 37 and the hook 30 provided on the peripheral frame 6 to prevent the balloon light emitting device 10 from overturning and to move the balloon light emitting device on the carrier. Preventing.

The generator 31 is a publicly known and generally rectangular parallelepiped, and uses a generator having an output suitable for the light emitting device. Note that the generator 31 may be installed at any position on the carrier 7. The generator 31 is also fixed by hooking the hook 30 to another hook 30 using a rope 32 or the like as a fastening means. In the figure, reference numeral 38 denotes a stopper for preventing the movement of the wheels 31a on the carrier 2 of the generator 31. It is desirable that the fastening means 32 be made of a material that can sufficiently withstand a rope, a rubber band, a wire, a string, or the like. Although not shown, as another fixing method of the generator 31, a fixing structure may be provided such that when the generator 31 is placed on the carrier 2, the stoppers protrude from the four corners and automatically block the generator 31. In this case, hooks and ropes are not required. Further, tools and the like can be placed in the empty space on the carrier 2.

The trolley for the balloon floodlight device of the present invention is generally provided with a balloon floodlight device installed on the bed of the trolley as shown in FIG. 1 and further tightened with a rope or the like. Track construction is performed with this balloon floodlight installed. Each time the work is completed, the truck should be moved to the appropriate position. Next, in order to replace the balloon projector of the balloon projector, the rope is detached from the hook, and then the projection 12e of the pole 12 is detached from the hole 13f of the cylindrical portion 13, and the lower pole is removed. 12a is removed from the cylindrical portion 13 together with the balloon projector 11. Conversely, in order to install the balloon floodlight 11 on the cylindrical portion 13, the lower pole 12a is inserted into the cylindrical portion 13, and the projection 12e of the pole 12a is rotated into the hole 13f of the cylindrical portion 13. Fit and fix.

Next, a second embodiment will be described. The description of the common parts with the first embodiment is omitted. The trolley B for the balloon floodlight can be used as an independent unit by lowering the balloon floodlight 10a together with the generator 54 from the carrier. Therefore, the portion from the cylindrical portion 38a for inserting the pole 12 to the upper portion is the same as that of the first embodiment, and the description is omitted, and a different lower tripod support member 47 will be described. The structure of this example is intended for use on a trolley, use of the balloon floodlight 10a from the minecart on the ground, and replacement of a part of the balloon floodlight 10a. Therefore, the tripod support member 47 employs a replaceable structure for the balloon projector at the upper part, an extendable structure for the extension of the tripod, and a detachable fixing structure to the carrier. Specifically, the tripod support member 47 is formed integrally with a tubular portion 47a and side tubular portions 38a, 38b, and 38c that extend in three directions on the ground and into which the intermediate member 39 is inserted. A hole 47f is formed in the upper part of the cylindrical portion 47a so as to be fitted with the rotation stopping projection 12e of the pole 12a supporting the balloon floodlight 11. The intermediate member 39 and the side cylindrical portion 38 are formed with screws that can be screwed to the ends of which the length is adjustable. The intermediate member 39 is further provided with a leg member 40 having a castor 56 at an end thereof. Each screw is firmly fixed with a tightening ring 60. The leg member 40 is provided as a single unit so that the balloon projector 10a can be moved on the ground. Accordingly, the leg member 40, the intermediate member 39, and the side tube portion 38 are rotated and loosened with each other, adjusted in length, and rotated again in the reverse direction to change the tightening length with the tightening ring 60. When the length adjustment width is small, a screw may be formed only in the leg member 40 and the intermediate member 39, and the side cylindrical portion 38 and the intermediate member 39 may be fitted with the hole and the protrusion. In order to fix the balloon floodlight device 1a to the carrier 7, three U-shaped receiving portions 55 that can protrude and retract in a direction matching the tripod support member 47 are supported on the carrier 7. An opening 7a is formed on the balloon light emitting device 1a side so that the receiving portion 55 can be easily pulled out by hand. A reinforcing frame 7b is fitted on the peripheral wall of the opening 7a. The height of the reinforcing frame 7b is made slightly higher to have a stopper function for the receiving portion 55 to come and go. The receiving portion 55 is pivotally supported within the reinforcing frame 7b fitted to the opening 7a, and when not in use, hangs down by its own weight as shown in FIG. 6, abuts on the reinforcing frame 7b and is buried from the surface of the loading platform 7. I have. At the time of use, as shown in FIG. 7, it is rotated on the shaft 55a and protrudes from the surface of the contact carrier 7 to the reinforcing frame 7b. The receiving portion 55 has a U shape, but may have another shape as long as the ends of the legs of the tripod support member can be locked and fixed. The above is an example of the fixing structure of the tripod support member on the carrier, but other methods are of course possible. For example, two holes are provided for each leg, through which the wire on the loading side penetrates, and each end of the leg supporting member is fixed to the loading platform by a wire or the like, or the end of the leg supporting member protruding from the loading platform in advance. A stopper for locking the portion may be provided. In the latter case, there is a drawback that the stopper cannot always be used as a one-sided carrier after the stopper constantly protrudes above the carrier and the balloon projector is lowered.

The fixing of the balloon projector 1a to the carrier 7 is performed by loosening the tightening ring 60 between the side cylindrical portion 38 of the tripod support member 47, the intermediate member 39, and the leg member 40, so that the balloon projector 1a is fixed on the carrier 7 of the trolley. The length is reduced until it matches the receiving portion 55. The tripod support member 47 is fitted to the receiving portion 55, and is tightly fixed with a tightening ring 60. In order to prevent the balloon projector 1a from falling down even in bad weather, and to prevent the tripod support member 47 from coming off the receiving portion 55 due to the loosening of the tightening ring 60 during the operation of the minecart during operation. As shown in FIG. 5, a fastening member 32 such as a rope, a string, a wire, or an elastic string may be added to the hook portion 37 and the hook 30 of the pole. Next, in order to lower the balloon projector 1a from the carrier 7, the intermediate member 39 of the tripod support member 47, the leg member 40 stretched from the receiving portion 55 by loosening the fastening ring 60 of the leg member, and the intermediate member 39 , The leg member 40 is removed from the receiving portion 55, and the balloon projector 1a is lowered from the carrier 7. After the balloon projector 1a and the generator 54 are lowered from the carrier 7, the carrier 7 is flush with the carrier as shown in FIG. 6, and the general carrier can be placed on the carrier. As shown in FIG. 8, the balloon projector 1a and the generator 54 are extended and the leg member 40 and the intermediate member 39 are extended, and the balloon projector 1a is firmly fixed with the tightening ring 60, and the balloon projector 1a is mounted. Stabilize. The generator 54 is installed at an appropriate position. When the balloon projector 1a is used independently, a stand may be further provided on the tripod support member 47 so that the small generator 54 can be mounted on the tripod support member 47 in order to eliminate rollover due to wind. .

[Effect of the invention]

 Since the present invention has the above configuration, the following effects can be obtained.

Since a light and compact trolley for a balloon light projecting device dedicated to track construction is formed, the light projecting device can move freely on the track, and the light projecting device easily moves in accordance with the construction work. It can be expected that the man-hour will be greatly reduced and the efficiency of the construction will be increased.

In order to prevent the balloon floodlight from overturning due to wind or the like, a hook is provided on the periphery of the truck bed, and a rope, a string, a wire, a rubber string, or the like is hooked and fixed to the hook of the pole and the hook. This eliminates the need for a conventional large-scale outrigger and can be easily installed. In addition, although simple, the balloon floodlight is fixed by the weight of the minecart, so that it is possible to sufficiently prevent falling. Therefore, in the first embodiment of the present invention, the movement of the balloon projector during operation can be greatly reduced. Also, the falling down of the balloon floodlight due to crosswinds can be prevented by the weight of the truck, in addition to the rigid fixing structure of the support plate to the carrier. In addition, since ropes are used to stretch the hooks on the side of the trolley and the hooks on the poles, it can be prevented reliably.

The balloon floodlight is easily removable from the carrier and can be repaired and replaced. In the case of the first embodiment, the pole is pulled out from the cylindrical portion. In the case of the second embodiment, the entire balloon light emitting device is removed from the receiving portion.

The fixing of the balloon projector mounted on the carrier of the first embodiment to the carrier was carried out by clamping the carrier including the sub-frame with the support plate and the contact plate and fastening them via bolts. Even if it is a thin wooden board, it has sufficient strength, and there is no fear that the cylindrical part supporting the balloon projector will be deformed or peeled off.

[0027] A plurality of hooks are provided on the side surface of the carrier, and the hooks and the hooks of the poles of the balloon projector are fastened with a fastening member such as a rope so that the balloon projector on the carrier can be mounted. The balloon can be fixed securely, the wind resistance in bad weather can be increased, and the balloon projector can be prevented from falling down.

In the case of the second embodiment, since the casters are provided on the leg members of the balloon floodlight device, the balloon floodlight device can be easily moved while working alone.

In the case of the second embodiment, since the receiving portion for supporting the tripod support member is provided so as to be able to protrude and retract from the carrier, it is easy to attach the balloon projector to the carrier. Can be used for applications.
