For example, there is no power supply near the site, and the cable must be pulled over a long distance, and the height, aspect and angle of the lighting are adjusted. difficult. Some mobile lighthouses have also appeared on the market. For example, Chinese Patent Application No. 200720118922.8 discloses a mobile lighthouse comprising a light panel assembly (1) and a lifting rod connected to the light panel assembly (1). a power supply device for supplying power to the lamp panel assembly (1), characterized by further comprising a vehicle body (3) connected to the lifting rod (2), the vehicle body (3) being provided below There are wheels (4) and a support rod (5) of adjustable length for fixing the position of the moving lighthouse. Although the mobile lighthouse is convenient to move and has high illumination brightness, the height adjustment of the light pole is not flexible enough, and the lighthouse and the frame are relatively fixed, so that the illumination direction cannot be changed without the frame being fixed, and therefore, the application is limited. .

Summary of the invention

The object of the present invention is to provide a novel mobile lighthouse device, which not only has high illumination height and direction adjustment, but also has strong field adaptability, simple structure and good use effect.

In order to achieve the above object, the present invention provides a novel mobile beacon apparatus, comprising a movable frame, wherein the movable frame is provided with a generator set, a lamp holder provided with a lamp, and a lifting lamp pole, wherein The lifted light pole includes a plurality of joint rods which are sleeved from bottom to top in sequence, and the upper one of the poles is sequentially inserted into the inner cavity of the next section of the rod, and can slide along the inner cavity of the next section of the rod. A wire rope is connected to the lower portion of the (N+1)th post, and the wire rope is connected to the pulley on the side of the upper portion of the Nth post and is connected downward to the (N-1)th post, the first post The rotating base provided at the bottom thereof is rotatably connected to the movable frame, and the power driving mechanism for driving the second connecting rod to lift and lower is vertically disposed on the side of the first connecting rod, and N is an integer greater than or equal to 2. The lamp holder is disposed at an upper end of the uppermost one of the posts.

The invention has the beneficial effects that the new structure design of the light pole lifting mechanism and the rotating base realizes flexible adjustment of the lighthouse in the lighting height and the lighting direction, and is easy to operate and use, and can be well applied to different environments in the field. In addition, the device has a simple overall structure, is not only easy to manufacture and install, but also has a compact structure and a small footprint, so that it can be easily moved and used immediately in the occasion where temporary lighting is required.

The rod 8 includes a plurality of joint rods which are sequentially sleeved from bottom to top, and the upper one of the rods is sequentially inserted into the inner cavity of the next section, and can be inserted along the inner cavity of the next section Slip. In order to realize the stepwise rise of each of the joints, a wire rope 9 is connected to the lower portion of the (N+1)th link, and the wire rope 9 is connected to the pulley 10 on the side of the upper portion of the Nth link and is connected downward to the first ( N-1) on the joint, where N is an integer greater than or equal to 2. In order to facilitate the adjustment of the illumination direction, the first joint 1 is rotatably connected to the movable frame 6 via a rotating base 12 provided at the bottom thereof, and the first section 1 is vertically disposed on the side of the post for driving the second joint The power driving mechanism for lifting and lowering is a hydraulic cylinder 7 in this embodiment. The lamp holder 14 is disposed at an upper end of the uppermost one of the links, and the front end of the movable frame 6 is hinged with a foldable drawbar 24.

The lifting process of the lifting lamp pole 8 will be further described below with reference to Figs. As shown in Figures 2 and 3, the wire rope connected to the lower portion of the fifth post 5 is bypassed by the pulley on the upper side of the fourth post 4 and connected downward to the side of the third post 3; The wire rope at the lower portion of the joint post 4 bypasses the pulley on the side of the upper portion of the third joint rod 3 and is connected downward to the side of the second joint rod 2; the wire rope connected to the lower portion of the third joint rod 3 bypasses the second section The pulley on the side of the upper side of the post 2 is connected downward to the side of the first joint 1; the first joint 1 is fixed to the movable frame 6, and the second joint 2 is directly provided by the first The hydraulic cylinder 7 on the side of the one post 1 is driven, and the piston rod 13 of the hydraulic cylinder 7 is fixedly connected with the second joint rod 2 to drive the second joint rod 2 to move up and down.
