Description

Technical Field

[0001] The present invention relates to the technical field of portable lighthouses, and in particular to a self-loading and unloading portable lighthouse. Background Art

[0002] Lighthouses are currently commonly used lighting tools in emergency situations such as rescue and repair. Existing large mobile lighting towers generally weigh more than 1 ton and are huge in size. They need to be transported by large trucks, and loading and unloading requires auxiliary tools such as cranes or forklifts. The loading and unloading of mobile lighting towers takes a long time to prepare for emergency repairs, delaying precious time for emergency repairs.

[0003] The invention patent with announcement number "CN106678666A" and name "High-mobility lighthouse easy to load and unload" discloses a lighthouse, including: a lighthouse body consisting of a lighting device, a power supply device for providing power to the lighthouse, a control device and a frame device. The high-mobility lighthouse is also provided with a lifting mechanism that can lift the lighthouse body. The lifting mechanism is composed of three or four groups of lifting support devices distributed around the lighthouse body that can lift the lighthouse body and a telescopic device that can expand or retract the lifting support devices.

[0004] However, the existing lighthouses that are easy to load and unload use a spider-leg lifting mechanism, in which the four legs are lifted and lowered at the same time to achieve the purpose of getting on and off the vehicle. This structure is complex and requires high synchronization of the four legs, resulting in high production costs; at the same time, it takes up a large space during loading and unloading, and can only be carried out on a flat and open ground.

[0005] To this end, how to design a self-loading and unloading portable lighthouse so that it can use a more reliable mechanism to achieve autonomous loading and unloading of the lighthouse, and reduce the restrictions of terrain and space on the autonomous loading and unloading operations of the lighthouse, thereby improving the practicality of the portable lighthouse and reducing production costs. This is a technical problem that technical personnel in this field need to solve. Summary of the invention

[0006] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a self-loading and unloading portable lighthouse, so that it can adopt a more reliable mechanism to realize the autonomous loading and unloading of the lighthouse, and reduce the restrictions of terrain and space on the autonomous loading and unloading operation of the lighthouse, thereby improving the practicality of the portable lighthouse and reducing production costs.

[0007] The objective of the present invention is achieved through the following technical solutions:

The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0035] The present invention provides a self-loading and unloading portable lighthouse 10, such as Figure 1 and Figure 2 As shown, it includes: a lighthouse body 100, a lighting device 200 and a self-loading and unloading device 300.

[0036] The lighting device 200 is installed on the lighthouse body 100. The lighthouse body 100 is provided with a power supply for providing power to the lighting device 200 and an integrated controller (not shown) electrically connected to the lighting device 200. The self-loading and unloading device 300 is provided at the bottom of the lighthouse body 100. The bottom of the lighthouse body 100 is provided with a slide rail 110 (such as Figure 2 shown).

[0037] like Figure 2 As shown, the lighting device 200 includes: an angle-adjustable lamp 210, and a hydraulic telescopic rod 220 for adjusting the height of the lamp 210, and the hydraulic telescopic rod 220 is telescoped by an integrated controller. During use, the hydraulic telescopic rod 220 lifts the lamp 210 to a suitable height, and the integrated controller controls the lamp 210 to adjust its angle so that it can provide lighting for a designated area.

[0038] To facilitate loading and unloading, Figure 3 and Figure 4As shown, the self-loading and unloading device 300 of the present invention includes: a bottom frame 310, a top frame 320, an X-shaped connecting frame 330 and an extension frame 340. The lower end and the upper end of one side of the X-shaped connecting frame 330 are hinged to the bottom frame 310 and the top frame 320 respectively, and the lower end and the upper end of the other side are slidably connected to the bottom frame 310 and the top frame 320 respectively. The X-shaped connecting frame 330 is provided with a cylinder driving assembly 350 which can drive the X-shaped connecting frame 330 to open and close, thereby driving the top frame 320 to rise and fall. Under the action of hydraulic pressure, the piston rod of the cylinder driving assembly 350 is extended or shortened, thereby changing the distance at the intersection of the top frame 320 and the X-shaped connecting frame 330, thereby realizing the opening and closing of the X-shaped connecting frame 330 and the lifting and falling of the top frame 320. Driven by the cylinder driving assembly 350, the self-loading and unloading device 300 has a closed state (such as Figure 3 ) and the expanded state (as Figure 4 shown).

[0039] Moreover, if Figure 5 As shown, the extension frame 340 is slidably disposed on the top frame 320, and the slide rail 110 of the lighthouse body 100 is fixedly connected to the extension frame 340. In other words, the lighthouse body 100 and the extension frame 340 form a whole, and the two can slide relative to the top frame 320. Preferably, in this embodiment, balls (not shown) are provided between the extension frame 340 and the top frame 320, and between the top frame 320 and the slide rail 110, so that the friction coefficient during relative sliding can be reduced, so that the lighthouse body 100 and the extension frame 340 can slide relative to the top frame 320 more easily.

[0040] In combination with the above structure, the working principle of the self-loading and unloading device 300 of the present invention is explained below:

[0041] Initially, if Figure 2 As shown, the self-loading and unloading device 300 is completely located directly below the lighthouse body 100, the self-loading and unloading device 300 is in a closed state, and the extension frame 340 is retracted in the top frame 320;

[0042] During the autonomous loading process, first, the truck 20 is driven to the vicinity of the lighthouse 10, and the oil cylinder drive assembly 350 drives the X-shaped connecting frame 330 to open and the top frame 320 to rise, that is, the self-loading and unloading device 300 changes from the closed state to the unfolded state, and the lighthouse body 100 is lifted (such as Figure 6 As the cylinder drive assembly 350 is driven, the X-shaped connecting frame 330 is continuously deformed, and the top frame 320 is gradually raised until the top frame 320 is just above the bottom of the compartment of the truck 20. Then, the staff pushes the lighthouse body 100 toward the compartment (as shown in FIG. Figure 7As shown), the extension frame 340 and the lighthouse body 100 slide relative to the top frame 320 under the action of the thrust, and the extension frame 340 extends out from the top frame 320; at this time, the extension frame 340 and the lighthouse body 100 enter the carriage. Then, the cylinder drive assembly 350 drives the X-shaped connecting frame 330 to close, and the self-loading and unloading device 300 gradually returns to the closed state. Since the lighthouse body 100 and the extension frame 340 have been boarded into the carriage, the height position of the top frame 320 is inconvenient during this closing, and the bottom frame 310 is gradually lifted with the change of the X-shaped connecting frame 330 until it fits with the top frame 320 (as shown in FIG. 1 ). Figure 8 Then, the staff pushes the bottom frame 310 and the top frame 320 toward the lighthouse body 100, so that the extension frame 340 retracts into the top frame 320, and the self-loading and unloading device 300 is reset to the bottom of the lighthouse body 100, thus completing the self-loading operation;

[0043] During the autonomous unloading process, the order of changes in the self-loading and unloading device 300 is opposite to that during the above-mentioned loading process. The top frame 320, the bottom frame 310, and the X-shaped connecting frame 330 move relative to the extension frame 340 and the lighthouse body 100, so that the self-loading and unloading device 300 except the extension frame 340 is suspended outside the car; then driven by the cylinder drive assembly 350, the X-shaped connecting frame 330 opens and drives the bottom frame 310 to descend until the bottom frame 310 is pressed on the ground. Then the lighthouse body 100 is pushed out of the car and slid to the top of the top frame 320. At this time, the extension frame 340 retracts back into the top frame 320, and under the drive of the cylinder drive assembly 350, the self-loading and unloading device 300 gradually changes back to the retracted state, and the lighthouse body 100 gradually falls to the ground, thus completing the autonomous unloading operation.

[0044] It should be noted that compared with the prior art, the self-loading and unloading device 300 of the present invention has the characteristics of simple structure, small space occupation, and convenient operation. Specifically, the self-loading and unloading lifting mechanism commonly used in the prior art adopts a spider-leg style, and its four legs are installed by oil cylinders to achieve simultaneous lifting and lowering, thereby achieving the purpose of lifting. However, this spider-leg style self-loading and unloading lifting mechanism has obvious defects: first, the structure of this spider-leg style is complex, and the synchronization requirements of the four legs are high, and its production cost is relatively high; second, during loading and unloading, the four legs are spread outward, and the space required is relatively large; third, the spider-leg style lifting mechanism can only play a lifting role, and after lifting the lighthouse, it also needs the cooperation of the truck to perform the reverse operation, and then let the car body be under the lifted lighthouse, so as to complete the loading. Such operation steps are relatively cumbersome and require high operation of the staff;

[0045] The self-loading and unloading device 300 of the present invention can overcome the above-mentioned defects, thereby achieving a better self-loading and unloading effect. First, the self-loading and unloading device 300 utilizes the principle of geometry. During the lifting process, the top frame 320 and the bottom frame 310 always remain parallel, thereby achieving a smooth lifting of the lighthouse body 100, and the self-loading and unloading device 300 only requires one cylinder drive assembly 350 to drive the X-shaped connecting frame 330 to open and close, thereby driving the top frame 320 to lift and lower. Compared with the spider leg style of the prior art, the self-loading and unloading device 300 has a simpler structure and a more economical production cost. Furthermore, during the loading and unloading process, the top frame 320 and the bottom frame 310 of the self-loading and unloading device 300 are lifted and lowered vertically, and their projected area does not change. Compared with the spider leg style of the prior art, the self-loading and unloading device 300 does not require additional expansion during operation, and the projected area and space it occupies are smaller, which can be better adapted to different rescue sites. Secondly, during the loading and unloading process, the truck does not need to cooperate with the operation. After the self-loading and unloading device 300 lifts the lighthouse body 100, the staff can smoothly push the lighthouse body 100 to move it into the car. The position of the truck does not need to change during the whole process.

[0046] In this embodiment, if Figure 2 and Fig. 9 As shown, the bottom of the lighthouse body 100 is provided with four casters 120 (of course, six or eight casters can also be symmetrically arranged, etc.) to facilitate the movement of the lighthouse body 100 during transportation. However, when the lighthouse 10 is in lighting operation or in the process of transportation in the carriage, the lighthouse 10 with casters 120 is prone to slide due to tilting and bumping. In order to avoid these situations, the design of the self-loading and unloading device 300 of the present invention itself has an anti-slip function. For example, when the lighting is in operation, the self-loading and unloading device 300 is slightly unfolded under the drive of the cylinder drive assembly 350, so that the bottom frame 310 is lowered to press the ground. At this time, the self-loading and unloading device 300 and the casters 120 bear the gravity of the lighthouse 10 together, and the self-loading and unloading device 300 and the ground are in sliding friction, which increases the friction force that the lighthouse 10 needs to overcome when sliding, thereby playing an anti-slip role; similarly, during the transportation process in the carriage, the self-loading and unloading device 300 also contacts the bottom of the carriage, thereby increasing the friction force that the lighthouse 10 needs to overcome when sliding, and also plays an anti-slip role. In this way, the lighthouse 10 is not prone to sliding due to tilting or bumping, and can be more stable when placed.

[0047] Preferably, the bottom surface of the bottom frame 310 is provided with a plurality of foot pads (not shown), which are in direct contact with the ground so that the bottom frame 310 is suspended, thereby reducing the wear of the bottom frame 310 during use. The foot pads are made of rubber, which can effectively reduce noise and adapt to various uneven ground surfaces.

[0048] Furthermore, during the self-loading and unloading process, in particular, the lighthouse 10 is Figure 7 The status shown changes to Figure 8 During the state shown, the lighthouse body 100 slides into the carriage, but due to the lack of anti-slip limit, Figure 8 In the state shown, it is easy to fall backwards, which poses a certain safety hazard. To this end, the present invention combines the state change of the self-loading and unloading device 300 to design a special rotation-limiting component 400 on the lighthouse body 100.

[0049] Specifically, Fig. 9 As shown, a rotation limiting assembly 400 is provided near each caster 120. Fig.10 As shown, the rotation limiting assembly 400 includes: a base 410, a deflection member 420 and a reset elastic member 430. The base 410 is fixedly arranged at the bottom of the lighthouse body 100, the deflection member 420 is rotatably arranged in the base 410, and the reset elastic member 430 provides elastic force for the deflection member 420. The deflection member 420 is provided with a friction end 421 and a trigger end 422. The top frame 320 abuts against or moves away from the trigger end 422 of the deflection member 420, thereby causing the friction end 421 of the deflection member 420 to move away from or contact the caster 120. That is to say, when the extension frame 340 is retracted in the top frame 320, the trigger end 422 is squeezed by the top frame 320, the reset elastic member 430 is compressed, and the friction end 421 of the deflection member 420 is away from the caster 120; when the extension frame 340 slides out, the top frame 320 and the trigger end 422 are away from each other, the reset elastic member 430 pushes the deflection member 420 to rotate, so that the friction end 421 is pressed on the caster 120 to limit the rotation of the caster 120.

[0050] Preferably, the trigger end 422 of the deflection member 420 is provided with a freely rotatable drum 423 (such as Fig.10 As shown in the figure, the rotating drum 423 is a high-strength rubber structure. When the extension frame 340 is retracted, the rotating drum 423 directly contacts the top frame 320. The freely rotating rotating drum 423 can reduce the sliding friction between the extension frame 340 and the trigger end 422, thereby allowing the trigger end 422 to be smoothly lifted to avoid jamming. A rubber pad (not shown) is provided on the friction end 421 of the deflection member 420. When the top frame 320 and the trigger end 422 move away from each other, the deflection member 420 rotates, and the rubber pad on the friction end 421 will press against the wheel surface of the caster 120, thereby limiting the rotation.

[0051] The design principle of the rotation limiting component 400 is as follows:

[0052] During the autonomous loading process, the staff pushes the lighthouse body 100 into the carriage. During this period, the extension frame 340 gradually slides out from the top frame 320. First, the top frame 320 will first move away from the caster 120 (hereinafter referred to as the front wheel) in the forward direction of the lighthouse body 100, and then the top frame 320 no longer resists the trigger end 422. The deflection member 420 deflects under the action of the reset elastic member 430, and then the friction end 421 presses on the wheel surface of the caster 120, and the front wheel is restricted from rotating. At this time, the caster 120 (hereinafter referred to as the rear wheel) at the rear has not yet separated from the top frame 320 and is not restricted. After the extension frame 340 slides out completely, the lighthouse body 100 completely enters the carriage. At this time, the front and rear wheels are both restricted from rotating, and the lighthouse 10 is not easy to slip backwards; similarly, during the autonomous unloading process, as the top frame 320 is gradually pulled out, the front and rear wheels are restricted from rotating in turn, and finally they are also contacted and restricted in reverse order.

[0053] It should be emphasized that the rotation limiting assembly 400 and the caster 120 are arranged in a sequence, and the reason for setting such a sequence is to immediately limit the rotation of the caster 120 when it contacts the carriage (when entering the carriage). In other words, when the lighthouse body 100 is pushed into the carriage, even if the force is stopped halfway, the lighthouse 10 is not easy to slide backward and fall because the front wheel has been restricted from rotating, thereby fully ensuring the stability and safety during the self-loading and unloading process.

[0054] In other embodiments, a plurality of hanging rings 101 are arranged around the lighthouse body 100 (eg Figure 2 As shown in FIG. 1 , a plurality of lifting rings 101 are fixedly mounted on the outer surface of the lighthouse body 100 by welding or threaded connection. With the cooperation of the gantry or the crane, the staff can also choose to use the lifting rings 101 to load or unload the lighthouse 10.

[0055] In summary, the self-loading and unloading portable lighthouse 10 of the present invention can adopt a more reliable mechanism to realize autonomous loading and unloading of the lighthouse, reduce the restrictions of terrain and space on the autonomous loading and unloading operation of the lighthouse, thereby improving the practicality of the portable lighthouse and reducing production costs.

[0056] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
