Description

Technical Field

[0001] This invention relates to the field of transportation equipment, and more particularly to a portable emergency light vehicle. Background Technology

[0002] With the increasing electricity consumption, especially during peak hours, power outages are prone to occur due to insufficient power supply from electric fields. For large public places, factories, or streets, simple emergency lights can solve the lighting problem for certain areas.

[0003] One type of retractable emergency high-mast light includes a base and a retractable light body rotatably mounted on the base. The base is equipped with a cable connecting the retractable light body to the vertical position. The retractable light body is raised and lowered via a lifting system, which uses a motor, an electromagnetic brake worm gear reducer, a safety coupling, a main wire rope, an auxiliary wire rope, a rope distributor, and a pulley block to drive the raising and lowering of the light panel. The worm gear reducer has strong self-locking capability. The main wire rope is connected to the auxiliary wire rope of the light panel via the rope distributor, preventing the auxiliary wire from tangling due to the tension of the main wire rope. Both the main and auxiliary wire ropes are made of high-strength, corrosion-resistant 619 type non-rotating galvanized steel wire rope. The lifting pulley block uses hot-dip galvanized A3 steel brackets, stainless steel shafts, and copper pulleys to ensure rust-free and flexible operation under normal atmospheric conditions. The lamp panel is equipped with six sets of guide pulleys and three or more braking devices. During the lifting or lowering of the lamp panel, the guide wheels, distributed at 120 degrees, roll along the surface of the lamp post to ensure that the lamp panel does not swing. The working surfaces of the guide wheels of the lamp panel that contact the surface of the lamp post are made of rubber using a hot-pressing process.

[0004] Because the cable is exposed, it is susceptible to outdoor environmental influences or accidental interference such as foreign objects hitting the cable, which can cause the cable to break. In this case, the retractable light body is prone to tilting and falling under its own weight, thus causing a safety accident. In other words, the existing retractable emergency high mast lights have poor safety performance. Summary of the Invention

[0005] The purpose of this invention is to provide a portable emergency light vehicle, which aims to solve the problem of poor safety performance of existing liftable emergency high mast lights.

[0057] Combination Figure 1-7 This invention provides a portable emergency light vehicle, comprising:

[0058] The portable emergency light vehicle also includes: a movable carrier 1 and a retractable light body 11, wherein the retractable light body 11 is rotatably connected to the movable carrier 1; and a portable emergency light vehicle further includes:

[0059] Tensioning member 2, which is connected to the movable carrier 1 and the retractable lamp body 11 respectively, is used to drive the retractable lamp body 11 to rotate from the horizontal state to the vertical state;

[0060] The limiting member includes:

[0061] A clamping assembly is mounted on the movable carrier 1 and is used to clamp the retractable lamp body 11 in a vertical state.

[0062] A limiting component is installed on the movable carrier 1 and is used to limit the clamping component after the clamping component clamps the retractable lamp body 11.

[0063] The retractable lamp body 11 is rotatably connected to the movable carrier 1 via a first rotating shaft 14.

[0064] In this embodiment, the movable carrier 1 includes a movable base 12, an operating table 13, and a retractable positioning mechanism 15. The movable base 12 includes wheels 122 and a body 121. Two wheels 122 are symmetrically arranged and rotatably connected to the body 121, so that the movable carrier 1 can move. The operating table 13 is fixedly connected to the upper end of the body 121 by bolting. It should be noted that the operating table 13 is used to store various control circuit boards and movable power sources such as batteries, which are used to power all electrical equipment of the lighting vehicle, so as to facilitate the user to control the lighting vehicle. This application will not elaborate further.

[0065] In this embodiment, four sets of retractable positioning structures are provided, each set located at one of the four corners of the vehicle body 121. Each retractable positioning structure includes a first telescopic rod 151 arranged laterally and a positioning rod 152 rotatably connected to the free end of the first telescopic rod 151. The first telescopic rod 151 can be fixed relative to the positioning rod 152 with bolts. When it is necessary to fix the light vehicle in the target position, the first telescopic rod 151 stored at the bottom of the vehicle body 121 is first extended outward, and then the positioning rod 152 is rotated so that the positioning rod 152 vertically touches the ground. Then, the positioning rod 152 and the first telescopic rod 151 are fixed relative to each other with bolts. Finally, after all the retractable positioning structures are unfolded in the above manner, the retractable light body 11 is firmly fixed in the target position.

[0066] It should be noted that the retractable lamp body 11 of this application includes multiple sections of second telescopic rods 111 and at least one lighting lamp 112 fixed on the free end of the uppermost second telescopic rod 111. It should be noted that the second telescopic rod 111 of this application is extended and retracted through a conventional lifting mechanism, such as the lifting system of a lifting high-mast lamp. This application does not make specific limitations. As long as the second telescopic rod 111 can move the lighting lamp 112 upward to the corresponding position after the vehicle body 121 moves to the target position, so as to achieve illumination of the corresponding area, it is sufficient. Therefore, this application will not elaborate further. In this embodiment, it should be noted that during the transportation of the light vehicle, the retractable light body 11 is in a horizontal state, that is, the retractable light body 11 extends horizontally, and the second telescopic rod 111 is retracted, making the overall structure of the light body more compact, thereby facilitating the transportation of the light vehicle. After the light vehicle arrives at the target position and is positioned, the tensioning member 2 drives the retractable light body 11 to rotate from the horizontal state to the vertical state, so that the retractable light body 11 extends vertically, so that the lighting lamp 112 has a certain height, thereby illuminating a certain area.

[0067] Meanwhile, in order to improve the safety performance of the light vehicle, this application provides a clamping component and a limiting component. Both the clamping component and the limiting component are located below the first rotating shaft 14. In actual use, the clamping component is used to clamp the retractable lamp body 11 in a vertical state, and the limiting component is used to fix the clamping component after clamping the retractable lamp body 11 onto the retractable carrier. This achieves relative fixation between the limiting component, the clamping component, and the retractable lamp body 11, reducing the possibility of the retractable lamp body 11 falling unexpectedly after the tensioning component 2 breaks, thus effectively improving the safety of the light vehicle.

[0068] Combination Figure 5 , Figure 6 and Figure 7In one specific embodiment, the movable carrier 1 includes a movable base 12 and an operating table 13 mounted on the upper end of the movable base 12. A first rotating shaft 14 is laterally rotatably connected to one end of the operating table 13. The clamping assembly and the limiting assembly are both mounted on the operating table 13. The clamping assembly includes:

[0069] The first clamping rod 3 is rotatably connected to the operating table 13;

[0070] The second clamping rod 31 is rotatably connected to the operating table 13, and a clamping space for the retractable lamp body 11 to be embedded is provided between the first clamping rod 3 and the second clamping rod 31.

[0071] A driving component 32 is mounted on the operating table 13 and connected to the first clamping rod 3 and the second clamping rod 31, for driving the first clamping rod 3 and the second clamping rod 31 to move closer together to clamp the retractable lamp body 11.

[0072] In this embodiment, the first clamping rod 3 and the second clamping rod 31 are horizontally arranged. After the retractable lamp body 11 changes from a horizontal state to a vertical state, the driving member 32 drives the first clamping rod 3 and the second clamping rod 31 to move closer to each other, so that the clamping space is reduced until the inner sides of the first clamping rod 3 and the second clamping rod 31 are pressed against the outer periphery of the second telescopic rod 111, thereby achieving the purpose of clamping and limiting the retractable lamp body 11. This is simple and easy to operate, and can effectively improve the connection stability between the retractable lamp body 11 and the operating table 13.

[0073] Combination Figure 5 , Figure 6 and Figure 7 In one specific embodiment, the first clamping rod 3 and the second clamping rod 31 are symmetrically arranged;

[0074] The first clamping rod 3 includes a first clamping part 33 and a first connecting part 34 connected to each other. The first clamping part 33 and the first connecting part 34 have an included angle. A second rotating shaft 35 is rotatably connected at the connection between the first clamping part 33 and the first connecting part 34. One end of the second rotating shaft 35 is vertically fixed to the operating table 13. The first connecting part 34 is provided with a first sliding hole 331 along its length direction.

[0075] The second clamping rod 31 includes a second clamping part 36 and a second connecting part 37 connected together. The second clamping part 36 and the second connecting part 37 have an included angle. A second rotating shaft 35 is also rotatably connected to the connection between the second clamping part 36 and the second connecting part 37. One end of the second rotating shaft 35 is vertically fixed to the operating table 13. The second connecting part 37 is provided with a second sliding hole 361 along its length direction.

[0076] The clamping space is located between the first clamping part 33 and the second clamping part 36. The first sliding hole 331 is slidably connected to a third rotating shaft 38. The third rotating shaft 38 is vertically inserted through the second sliding hole 361 and connected to the driving member 32.

[0077] In this embodiment, two connecting seats 7 are bolted to one end of the operating table 13. The lower end of one second rotating shaft 35 is rotatably connected to one connecting seat 7, and the other second rotating shaft 35 is rotatably connected to the other connecting seat 7. It can be understood that the first clamping rod 3 and the second clamping rod 31 have the same structure, only the installation position is different. Specifically, when clamping the retractable lamp body 11, the first clamping part 33 and the second clamping part 36 are arranged in parallel to provide better clamping strength for the retractable lamp body 11. Wherein, regardless of whether the retractable lamp body 11 is in a vertical or horizontal state, the first connecting part 3 4 and the second connecting part 37 are both arranged crosswise, so that the first sliding hole 331 and the second sliding hole 361 are connected at least partially. The third rotating shaft 38 is sequentially inserted into the connection between the first sliding hole 331 and the second sliding hole 361 in the vertical direction. The drive is connected to the third rotating shaft 38 and is used to drive the third rotating shaft 38 to move in the horizontal direction. During the movement, the third rotating shaft 38 compresses the inner sidewalls of the first sliding hole 331 and the second sliding hole 361, thereby driving the first clamping rod 3 and the second clamping rod 31 to rotate around the corresponding second rotating shaft 35, thereby changing the size of the clamping space.

[0078] Combination Figure 5 , Figure 6 and Figure 7 In one specific embodiment, the driving component 32 includes:

[0079] The first rack 4 is laterally slidably connected to the operating table 13, and one end of the first rack 4 is rotatably connected to the third rotating shaft 38.

[0080] The first gear 41 is rotatably connected to the operating table 13 and meshes with the first rack 4;

[0081] The first motor 42 is mounted on the operating table 13, and the first gear 41 is mounted on the output shaft of the first motor 42.

[0082] In this embodiment, a vertically arranged column 8 is welded to one end of the operating table 13. The first rotating shaft 14 is rotatably connected to the upper end of the column 8. Two connecting seats 7 are bolted to the column 8. Both the column 8 and the operating table 13 are provided with interconnected clearance holes 9 along their length. The clearance holes 9 are used for the first rack 4 to pass through. In this embodiment, the first gear 41 and the first motor 42 are both located inside the operating table 13 to protect the first gear 41 and the first motor 42. It should be noted that the teeth of the first gear 41 are arranged downwards.

[0083] In this embodiment, first sliding grooves (not shown) are provided laterally on both sides of the clearance hole 9. First sliding strips 91 are fixed on both sides of the first rack 4. The first sliding strips 91 are embedded in the first sliding grooves to achieve smooth sliding of the first rack 4. In actual use, the first motor 42 is started to drive the first gear 41 to rotate, which drives the first rack 4 to move in the horizontal direction, that is, to push the third rotating shaft 38 to rotate in the horizontal direction, thereby changing the size of the clamping space. After the retractable lamp body 11 is clamped, the first motor 42 is turned off so that the first rack 4 no longer slides, and the clamping space is relatively fixed, that is, the retractable lamp body 11 and the vehicle body 121 are relatively stable, thereby reducing the phenomenon of the retractable lamp body 11 falling unexpectedly after the tensioning component 2 breaks, and effectively improving the safety of the lamp vehicle.

[0084] Combination Figure 5 , Figure 6 and Figure 7 In one specific embodiment, the limiting component includes:

[0085] The first mounting block 51 is fixed to the side of the first connecting part 34 away from the first clamping part 33, and the first mounting block 51 is provided with a first mounting groove 511.

[0086] The second mounting block 52 is fixed to the side of the second connecting part 37 away from the second clamping part 36. The second mounting block 52 is provided with a second mounting groove 521. The first mounting groove 511 and the second mounting groove 521 form a connected limiting groove 54 when the first clamping part 33 and the second clamping part 36 clamp the telescopic lamp body 11. The limiting groove 54 is provided with guide slopes 541 on opposite sides.

[0087] The second rack 53 is slidably connected to the operating table 13 and meshes with the first gear 41. The second rack 53 is arranged parallel to the first rack 4. The second rack 53 is used to be embedded in the limiting groove 54 when the first clamping part 33 and the second clamping part 36 clamp the retractable lamp body 11.

[0088] In this embodiment, the first mounting block 51 is integrally formed on the first connecting portion 34 to improve the structural strength between the first mounting block 51 and the first connecting portion 34; the second mounting block 52 is integrally formed on the second connecting portion 37 to improve the structural strength between the second mounting block 52 and the second connecting portion 37; wherein, the first mounting block 51 is located above the second mounting block 52, and after the first clamping portion 33 and the second clamping portion 36 clamp the retractable lamp body 11, the end face of the first mounting block 51 facing away from the retractable lamp body 11 and the end face of the second mounting block 52 facing away from the retractable lamp body 11 are flush, at this time, the first mounting groove 511 and the second mounting groove 521 form a limiting groove 54.

[0089] In this embodiment, the second rack 53 passes through the clearance hole 9. Second sliding grooves (not shown) are laterally provided on both opposite side walls of the clearance hole 9. Second sliding strips 92 are fixed on both opposite sides of the second rack 53, and the second sliding strips 92 are embedded in the second sliding grooves to achieve smooth sliding of the second rack 53. In this embodiment, it should be noted that the guide slope 541 extends from the opening of the limiting groove 54 to the bottom wall of the limiting groove 54. That is, when the first rack 4 moves inward (towards the operating table 13), the second rack 53 moves outward (away from the operating table 13). When the first clamping part 33 and the second clamping part... When the holding part 36 is pressed against the outer periphery of the retractable lamp body 11, one end of the second rack 53 extends into and presses against the bottom wall of the limiting groove 54. That is to say, assuming that the cable 26 is broken, the retractable lamp body 11 will tilt in one direction under its own weight. At this time, the retractable lamp body 11 will inevitably squeeze the first clamping part 33 and the second clamping part 36, causing the first clamping part 33 and the second clamping part to be misaligned. At this time, since the second rack 53 is embedded in the limiting groove 54, it can prevent the first connecting part 34 and the second connecting part 37 from being misaligned, thereby preventing the retractable lamp body 11 from falling.

[0090] By using the second rack 53 and the limiting groove 54 together, the load between the first rack 4 and the column 8 can be relieved to a certain extent when the cable 26 breaks, thereby extending the service life of the first rack 4.

[0091] In one specific embodiment, the first rack 4 is rotatably connected to the upper end of the third rotating shaft 38, the second rack 53 includes a first tooth 531 and a second tooth 532 symmetrically arranged, the first tooth 531 meshes with the first gear 41, and the driving member 32 further includes:

[0092] The second gear 55 is rotatably connected to the operating table 13 and meshes with the second tooth 532;

[0093] The third rack 56 is laterally slidably connected to the operating table 13 and meshes with the second gear 55. One end of the third rack 56 is rotatably connected to the lower end of the third rotating shaft 38. The third rack 56 is arranged parallel to the second rack 53.

[0094] In this embodiment, both the first tooth portion 531 and the second tooth portion 532 include multiple spaced teeth. The teeth on the first tooth portion 531 face upwards, and the teeth on the second tooth portion 532 face downwards. The first tooth portion 531 and the second tooth portion 532 are integrally formed to improve the structural strength of the second rack 53. In this embodiment, the second gear 55 is located directly below the first gear 41, and the second gear 55 is rotatably connected to the inner wall of the operating table 13 via a shaft connection. While the first gear 41 drives the first tooth portion 531 to move horizontally, the second tooth portion 532... When driving the second gear 55 to rotate, it should be understood that the rotation direction of the first gear 41 and the rotation direction of the second gear 55 are always opposite. That is, when the first gear 41 rotates in a clockwise direction, the second gear 55 rotates in a counterclockwise direction, thereby realizing that the first rack 4 and the third rack 56 move in the same direction, while the second rack 53 moves in the opposite direction. For example, when the second rack 53 slides outward, the first rack 4 and the third rack 56 move inward at the same time, so as to drive the first clamping part 33 and the second clamping part 36 to come closer to each other, thereby clamping the retractable lamp body 11.

[0095] In this embodiment, the third rack 56 passes through the clearance hole 9 and is located directly below the second rack 53. The clearance hole 9 has a third sliding groove (not shown) on each of its two opposite side walls. The third rack 56 has a third sliding strip 93 fixed on each of its opposite sides. The third sliding strip 93 is embedded in the third sliding groove to achieve smooth sliding of the third rack 56. It should be noted that the teeth of the third rack 56 are facing upwards.

[0096] Combination Figure 5 , Figure 6 and Figure 7 In one specific embodiment, the first rotating shaft 14 is rotatably connected to the operating table 13, and the first rotating shaft 14 is fixedly connected to the retractable lamp body 11. The limiting component also includes a first cam 57, one end of which is fixed to one end of the first rotating shaft 14, for abutting against the upper end of the first clamping part 33 when the retractable lamp body 11 is in a vertical state.

[0097] In this embodiment, the first cam 57 is a disc cam, which includes a wheel portion and a protrusion connected to each other. The wheel portion is fixedly connected to one end of the first rotating shaft 14. The outer side wall of the protrusion is used to abut against the upper end of the first clamping portion 33 when the retractable lamp body 11 is in a vertical state. In this way, during the process of the retractable lamp body 11 changing from a horizontal state to a vertical state, it drives the first rotating shaft 14 to rotate, thereby driving the first cam 57 to rotate. When the retractable lamp body 11 is in a vertical state, the outer periphery of the protrusion abuts against the upper end of the first clamping portion 33, thereby limiting and positioning the first clamping portion 33.

[0098] In one specific embodiment, the limiting component further includes a second cam 58 symmetrical to the first cam 57. One end of the second cam 58 is fixed to the other end of the first rotating shaft 14 and is used to abut against the upper end of the second clamping part 36 when the retractable lamp body 11 is in a vertical state. The inner sides of the first cam 57 and the second cam 58 abut against the outer periphery of the retractable lamp body 11.

[0099] In this embodiment, it is understood that the first cam 57 and the second cam 58 have the same structure. The first cam 57 and the second cam 58 are symmetrically arranged at both ends of the first rotating shaft 14. When the retractable lamp body 11 is in a vertical state, the outer periphery of the protrusion of the second cam 58 abuts against the upper end of the second clamping part 36. That is to say, the first clamping part 33 and the second clamping part 36 are limited and fixed by the two cams, thereby reducing the misalignment of the first clamping part 33 and the second clamping part 36, effectively improving the connection stability between the retractable lamp body 11 and the column 8. At the same time, it reduces the load on the limiting component to a certain extent in the case of the cable 26 breaking, thereby extending the service life of the limiting component.

[0100] In one specific embodiment, the inner sides of the first clamping part 33 and the second clamping part 36 are both provided with a diamond layer 6 for abutting against the retractable lamp body 11.

[0101] In this embodiment, the diamond layer 6 has good wear resistance, thereby increasing the clamping strength of the first clamping part 33 and the second clamping part 36 on the retractable lamp body 11.

[0102] Combination Figure 2 , Figure 3 and Figure 4 In one specific embodiment, the tensioning member 2 includes:

[0103] The second motor 21 is fixed to the movable base 12;

[0104] The transmission component 22 includes a meshing third gear 221 and a fourth gear 222, wherein the third gear 221 is coaxially fixed to the output shaft of the second motor 21;

[0105] Rotating disk 23, which is coaxially and fixedly connected to the fourth gear 222;

[0106] The first tensioning wheel 24 is rotatably connected to the movable base 12;

[0107] The second tensioning wheel 25 is rotatably connected to one end of the retractable lamp body 11;

[0108] The cable 26 has one end wound around the outer periphery of the rotating disk 23, and the other end is sequentially wound around the first tension wheel 24 and the second tension wheel 25 and fixed to one end of the movable base 12.

[0109] In this embodiment, the second motor 21 is fixedly connected to the vehicle body 121 by bolting. The tooth diameter of the third gear 221 is smaller than that of the fourth gear 222. The first tension wheel 24 is rotatably connected to the column 8 by a shaft connection, and the second tension wheel 25 is rotatably connected to one end of the second telescopic rod 111 by a shaft connection. When it is necessary to change the placement state of the retractable lamp body 11, the second motor 21 is started, which drives the third gear 221 to rotate, thereby driving the fourth gear 222 and the rotating disk 23 to rotate synchronously, thereby changing the number of turns wound on the rotating disk 23. That is, changing the length of the exposed cable 26, thereby driving the retractable lamp body 11 to change from a horizontal state to a vertical state, or from a vertical state to a horizontal state.

[0110] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in the present invention, and these modifications or substitutions should all be covered within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
