Description

TECHNICAL FIELD

[0001] The application relates to the technical field of lighting vehicles, in particular to a lamp pole lifting anti-winding device and a lighting vehicle. BACKGROUND

[0002] As a highly mobile and flexible deployment special operation vehicle, the lighting vehicle has been widely used in night road construction, large-scale activity support, post-disaster emergency rescue, port operation and military field lighting and many other fields. Its core function is to provide large-area and high-intensity lighting for outdoor environments with insufficient or no light at all through an integrated high-power lighting system, so as to ensure operation safety, improve work efficiency and prolong the work time.

[0003] The traditional lighting vehicle is usually composed of a mobile chassis, a power generation system, a hydraulic or electric lifting system and a lighting system. Among them, the lifting lamp pole as a key component for carrying lighting lamps directly determines the lighting range and effect. Modern lighting vehicles generally use multi-section sleeve type lifting lamp poles which can be driven by built-in hydraulic cylinders or electric push rods to realize rapid lifting, so as to maintain a low closed height during transportation to meet the road regulation requirements, and to lift the lamp head to tens of meters or even higher in the air during operation to expand the lighting coverage radius.

[0004] The lighting lamp (lamp head) is usually installed at the top of the lifting lamp pole, and a high-power gas discharge lamp is integrated inside, which means that the cable connected to the lamp head not only needs to provide power for it, but also needs to transmit the control signal of the pan-tilt, for this reason, a composite cable integrating power transmission and signal control is drawn out from the lamp head and passes through the internal cavity of the lifting lamp pole, and finally connected to the power supply and control system in the vehicle body.

[0005] In view of the working characteristics that the lifting lamp pole needs to be frequently lifted and lowered, the cable connected to the lamp head must have corresponding stretching ability, so a spiral cable (also known as spring cable) is used, such cable is wound into a spiral shape through special process during manufacturing, so that it has significant elasticity, can naturally extend with the rising of the lamp pole, and spontaneously contract with the lowering of the lamp pole, effectively avoiding the problems of fatigue and fracture of rigid cable in repeated bending and difficulty in management of too long cable.

[0006] However, in practical applications, the spiral cable has a self-shrinking property, but during the lifting process, especially during the descent and recovery, the shrinking process of the cable is not always an ideal concentric shrinking. Due to the influence of factors such as the gravity of the cable itself, uneven internal stress release, external wind force or shaking during the lifting process, the cable is prone to deviate from its theoretical central axis and fall, resulting in twisting and winding of the spiral cable around the lamp post body. After multiple windings, it may cause local overstretching and twisting deformation of the cable, accelerate its aging and damage, and shorten the service life. If the cable is stuck, it may hinder the normal lifting of the lamp post, and even cause electrical safety accidents such as short circuit and electric leakage, seriously affecting the reliability and safety of the equipment.

[0007] Therefore, it is necessary to provide a lamp post lifting anti-winding device and a lighting vehicle to solve the above problems.

DETAILED DESCRIPTION

[0041] It should be noted that the embodiments and features in the present application can be combined with each other without conflict. The technical solutions in the embodiments of the present application will be described in detail below with reference to the drawings and in combination with the embodiments.

[0042] In order for those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be described in detail below with reference to the drawings and in combination with the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present application, not all. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor should be within the scope of protection of the present application.

[0043] As Figures 1-2As shown, the present application provides a lamp pole lifting anti-winding device and lighting vehicle, which is mainly applied to outdoor work, emergency rescue and engineering construction and the like occasions, and provides lighting support for night or low light environment. The lighting vehicle is usually integrally installed on various mobile vehicles or independent towing platforms, has good mobility, can be quickly deployed to the target area as needed and provide large range of lighting. Meanwhile, the lamp pole of the lamp pole lifting anti-winding device and lighting vehicle is arranged on the lighting vehicle and is mainly used for lighting. Specifically, the lamp pole lifting anti-winding device and lighting vehicle comprises a base 1, which is a support structure of the whole device. The manufacturing tolerance in the technical requirements for processing is executed according to GB / T1804-M level, and all welds are polished and smoothed, and the welding deformation is controlled within 2mm, so as to ensure the overall stability.

[0044] In order to realize effective lighting of the remote area, a lifting lamp pole 2 which can be greatly lifted is vertically arranged at the upper end of the base 1. The lifting lamp pole 2 adopts a multi-section sleeve structure and is stably telescoped through an internal hydraulic or electric drive device. The hydraulic or electric drive device is an electric cylinder or a hydraulic cylinder in the prior art, which will not be described here. The transportation height of the lifting lamp pole 2 in the closed state is set to be less than 2300mm to meet the height limit requirement of road driving. After the lifting lamp pole 2 is fully lifted, the maximum working height can be more than 15000mm, which can be lifted to a sufficient height and greatly expand the lighting coverage range.

[0045] A lamp head 5 is fixedly arranged at the end of the lifting lamp pole 2. The lamp head 5 is rotated horizontally by 360° and vertically by 330° through a pan-tilt structure. The rotating radius of the lamp head 5 is 400mm, and the horizontal and vertical rotating speeds are both 4r / min, so that the light can cover a wider area.

[0046] Meanwhile, the lamp head 5 is internally provided with a metal halide lamp tube. The power of the metal halide lamp tube is 1kW, the color temperature is 6500K, the light emission is natural light, the service life is 3000 hours, and the protection level is IP65, so as to adapt to the outdoor harsh environment.

[0047] In order to facilitate remote operation, the lamp head 5 supports remote control operation. The remote control distance of the remote control operation is not less than 30m, and the irradiation distance of the lamp head 5 is not less than 50m, so as to better set the lighting.

[0048] In order to facilitate the lifting of the lifting lamp pole 2, an operation table 3 is arranged on one side of the base 1. The operation table 3 is a control center of the whole lighting vehicle, and is integrated with a power socket, a limit socket, a hand control box socket, a fuse, a factory nameplate and a speed reducer and the like key components. They work cooperatively to ensure the stability, safety and convenience of the lifting operation.

[0049] Specifically, the external power supply is connected through the power socket to provide power for the entire lighting vehicle system, so that the electric energy is transmitted to the fuse through the built-in circuit. The fuse is the core guarantee of circuit safety, which monitors the current intensity in real time. When the system operating current exceeds the rated threshold, the fuse will immediately cut off the circuit, thereby effectively preventing the motor or other electrical components from being damaged due to overload.

[0050] Subsequently, the power is transmitted to the speed reducer and control circuit. At this time, the user issues instructions through the wired hand control box connected to the hand control box socket or the wireless remote control. The control system drives the speed reducer to operate, converts the electric energy into smooth torque output, and drives the lamp pole to rise and fall smoothly. At this time, the limit sensor installed on the lamp pole feeds back the position signal in real time through the limit socket, controls the lamp pole to operate within the set range, and prevents damage caused by excessive lifting.

[0051] Among them, the factory nameplate has key parameters such as equipment rated voltage, current, maximum lifting height, etc. It is the fundamental basis for users to correctly connect the power socket, set the limit point, and understand the capacity of the fuse and the performance of the speed reducer, so that the device can safely and efficiently operate within the design specification, and thus achieve the effect that the user can control the lifting of the lamp pole 2 through the operation table 3.

[0052] In order to prevent emergency situations such as power supply interruption or control system failure that may be faced in field operations, a handle 4 is provided on the operation table 3. The handle 4 is connected to the speed reducer through a mechanical transmission mechanism, such as a chain or gear transmission mechanism in the prior art, which is not described here. The transmission mechanism is connected to the speed reducer, so that the handle 4 can drive the lifting of the lamp pole 2 for lifting work.

[0053] It should be noted that under normal circumstances, the lifting of the lamp pole 2 is controlled by the buttons on the control box panel or the wireless remote control. Once an emergency occurs, the operator can rotate the handle 4 to manually drive the speed reducer to achieve the manual emergency lifting of the lamp pole 2, thereby enhancing the reliability and emergency protection capability of the equipment.

[0054] In order to control the power supply and rotation function of the lamp head 5, an electric cable 8 is provided on the lamp head 5. The electric cable 8 adopts a special spiral design, similar to the common spring wire, which has good stretch elasticity, so that it can naturally stretch as the lamp pole 2 rises, and automatically contract when the lamp pole 2 descends, preventing the pulling and kinking phenomenon that easily occurs during frequent stretching and contraction, thereby prolonging the service life of the electric cable 8.

[0055] And one end of the cable 8 extends into the inside of the lifting lamp pole 2, and is directly and firmly connected with the electrical interface of the lamp head 5, responsible for delivering power to the light source and the gimbal motor in the lamp head 5, and at the same time transmitting control signals to the gimbal controller, the other end of the cable 8 passes through the inner cavity of the lifting lamp pole 2, and finally leads out from the bottom of the lifting lamp pole 2, and is connected with the electrical control box on the lighting vehicle.

[0056] Embodiment one: in order to prevent the cable 8 from winding during lifting, as shown in Figure 1 Figure 3 And Figure 5 , a winding prevention device 6 is arranged at the bottom end of the lifting lamp pole 2, which includes a fixed plate 60 fixedly installed on the outer wall of the head end of the lifting lamp pole 2, and at least four groups of guide columns 61 are fixedly arranged on the fixed plate 60, which are distributed around the circumference of the fixed plate 60.

[0057] At the same time, the distribution circle of the guide column 61 is strictly coaxial with the center axis of the spiral line of the lifting lamp pole 2 itself, so as to facilitate the subsequent winding prevention operation.

[0058] It should be noted that the upper end of the guide column 61 is inclined outward, which constitutes a horn-shaped guide structure.

[0059] Therefore, during the descent of the lifting lamp pole 2, if the spiral cable 8 which is falling relaxed deviates from the theoretical center axis position and swings due to some reason, the horn-shaped guide column 61 array will effectively limit and correct it.

[0060] The eccentric cable 8 will first contact and hit the inner side of the inclined guide column 61, and under the guidance of the guide column 61, the falling path of the cable 8 will be forced to adjust and gradually gather back to the center axis position, thereby effectively preventing it from winding around the lifting lamp pole 2 itself due to eccentric swinging during falling, and ensuring that the cable 8 is always in an orderly extension state.

[0061] It should be noted that the overall processing technology requirement of the winding prevention device 6 is that the surface needs to be treated to have no obvious scratches, and the whole is flat without visible deformation, and the diagonal line installation error of the fixed plate 60 is controlled within 2mm, all the joints are firmly and tightly welded, and the tolerance is executed according to GB / T1804-M level, and after welding, the whole is sprayed with yellow paint, so as to achieve the effect of being eye-catching and anti-rust.

[0062] Embodiment two: in order to further flexibly use the cable 8 on the lifting lamp pole 2, better manage the cable 8, and prevent the surface of the cable 8 from being polluted during outdoor use.

[0063] As shown in Figures 1-11 ​As shown, a winding mechanism 7 is provided at the bottom end of the lifting light pole 2 above the fixed plate 60. The winding mechanism 7 includes a winding roller 74 rotatably mounted on the lifting light pole 2 via a bearing seat. The winding roller 74 is used to wind up the cable 8 that has loosened during the descent of the lifting light pole 2, so as to prevent it from piling up messily.

[0064] Meanwhile, a fixed base 71 is fixedly installed on one side of the fixed plate 60. A first motor 70 is installed on one side of the fixed base 71. The output shaft of the first motor 70 passes through the fixed base 71 and a small bevel gear 72 is fixedly installed thereon, so that the first motor 70 can be started to drive the small bevel gear 72 to rotate on the fixed base 71.

[0065] Furthermore, a large bevel gear 73 is fixedly installed on the outer circumference of the lower wheel arch of the take-up roller 74. The large bevel gear 73 meshes perpendicularly with the small bevel gear 72. When it is necessary to wind up the cable, the control system will start the first motor 70, drive the small bevel gear 72 to rotate, and then drive the large bevel gear 73 meshing with it to drive the take-up roller 74 to rotate together, thereby realizing the active winding function.

[0066] To protect the large bevel gear 73 and the small bevel gear 72 from dust and moisture intrusion and to prevent accidental contact, a cover 75 is fixedly installed on the outside of the large bevel gear 73 and the small bevel gear 72 to prevent dust intrusion and operator contact with moving parts, thereby improving safety.

[0067] Because lighting vehicles operate in harsh environments such as dust and mud for extended periods, it's crucial to prevent dust, oil, or other contaminants from adhering to the surface of cable 8. These contaminants could soil the winding roller 74 during winding, potentially entering the equipment and accelerating the aging and wear of the cable 8's outer sheath. Figures 5-9 As shown, a cleaning assembly 76 is provided on one side of the fixed plate 60. The cleaning assembly 76 includes a column 760 fixedly installed on the side of the fixed plate 60. A vertical plate 761 is fixedly installed on one side of the column 760. In order to provide a stable and straight cable 8 for subsequent cleaning operations, two sets of limiting units 762 are provided on one side of the vertical plate 761. The two sets of limiting units 762 are used to limit and rewind the cable 8 by being arranged in parallel vertically.

[0068] Specifically, such as Figures 3-4 As shown, the limiting unit 762 includes a fixing rod 763 horizontally fixed on the vertical plate 761, and a limiting ring 764 fixedly installed at the end of the fixing rod 763. The limiting ring 764 is composed of two semi-circular arc rings, and locking bolts 766 are provided on both sides of the two semi-circular arc rings so that the limiting ring 764 can be assembled into a whole. Thus, the user can open the limiting ring 764 by loosening the locking bolts 766, which facilitates the insertion and removal of the cable 8.

[0069] At the same time, at least two sets of V-blocks 765 are fixedly installed inside the limiting ring 764. Each V-block 765 is equipped with four limiting rollers 767 via a rotating shaft. The limiting rollers 767 are distributed around the central axis of the limiting ring 764. Their arc-shaped working surfaces together form a channel that allows the cable 8 to pass through but also constrains its radial movement.

[0070] When the cable 8 passes through the four limiting rollers 767, the limiting rollers 767 can roll freely with the cable, thereby reducing the sliding friction with the surface of the cable 8. The surface of the limiting rollers 767 is covered with flexible wear-resistant materials such as engineering plastics or rubber to protect the cable sheath.

[0071] Furthermore, an appropriate distance is maintained between the two sets of limiting units 762, and the upper and lower sets of limiting units 762 work together to force the cable 8 passing between them to remain in a straight vertical position, providing a basis for the subsequent cleaning work.

[0072] In order to clean the surface of cable 8, such as Figures 8-11 As shown, a cleaning unit 768 is provided at the position of the cable 8 in a vertical state. The cleaning unit 768 includes a fixing tube 769 fixedly installed on the column 760. The fixing tube 769 passes through the column 760 and the vertical plate 761. The fixing tube 769 is made of hard materials such as stainless steel. At the same time, a transport cavity is machined inside the fixing tube 769.

[0073] Meanwhile, a liquid storage tank 770 is fixedly installed on the other side of the column 760. The liquid storage tank 770 is used to store cleaning fluid or cleaning agent. A pump body (not shown in the figure) is integrated inside the liquid storage tank 770. The output end of the liquid storage tank 770 is fixedly connected to the input end of the fixed pipe 769. Thus, the cleaning fluid or cleaning material in the liquid storage tank 770 can be pumped into the fixed pipe 769 by the pump body for subsequent cleaning.

[0074] Furthermore, a temporary storage ring 771 is fixedly connected to the output end of the fixed tube 769. The temporary storage ring 771 is sleeved on the outside of the cable 8. At the same time, an annular cavity 772 is provided inside the temporary storage ring 771. The cavity 772 is connected to the outlet of the fixed tube 769 so that the cleaning fluid or cleaning material inside the fixed tube 769 can be introduced into the cavity 772 for use.

[0075] Meanwhile, multiple micro nozzles 773 are evenly installed on the inner wall of the temporary storage ring 771. The spray direction of the nozzles 773 is all directed towards the cable 8. When the system starts the cleaning program, the pump in the storage tank 770 starts to work, pumping the cleaning fluid into the fixed pipe 769, and then delivering it to the cavity 772 of the temporary storage ring 771. Finally, it is evenly sprayed out from all the nozzles 773, washing the surface of the cable 8 that is passing through the center of the ring from all directions.

[0076] And in order to further clean the surface of the cable 8, a gear seat 774 is fixedly arranged at one side of the vertical plate 761 at the middle position, a pinion 781 is installed on the gear seat 774 through a bearing, and a second motor 780 is fixedly arranged at the lower end of the gear seat 774, the output end of the second motor 780 penetrates the gear seat 774 and is fixedly connected with the pinion 781, so that the second motor 780 can be started to drive the pinion 781 to rotate on the gear seat 774.

[0077] Meanwhile, an installation ring 776 is rotatably installed at the bottom end of the temporary storage ring 771 through a bearing, the outer edge of the installation ring 776 is fixedly provided with a large gear 777, the large gear 777 is meshed with the pinion 781, so that when the second motor 780 is started, the second motor 780 can be started to drive the large gear 777 and the pinion 781 to drive the installation ring 776 to rotate relative to the temporary storage ring 771.

[0078] In order to protect the large gear 777 and the pinion 781 from dust and moisture and prevent accidental contact, a shell 775 is fixedly arranged outside the large gear 777 and the pinion 781, so as to prevent dust from entering and prevent operators from contacting moving parts, thereby improving safety.

[0079] And a sponge block 778 is detachably arranged inside the installation ring 776, a through hole is formed in the center of the sponge block 778 to pass through the cable 8.

[0080] Therefore, when the installation ring 776 rotates, the sponge block 778 is driven to rotate at high speed, and the surface of the cable 8 just sprayed is comprehensively wiped, on the one hand, stubborn stains are further brushed off, and on the other hand, excess liquid is absorbed, so that the cable 8 is kept relatively dry and clean when being wound.

[0081] Meanwhile, a buckle 779 is fixedly arranged at the connection between the installation ring 776 and the bottom end of the sponge block 778, the buckle 779 is used to lock the installation ring 776 and the sponge block 778, when the sponge block 778 needs to be replaced or cleaned, the buckle 779 can be opened to take it down.

[0082] When the operator controls the lifting lamp pole 2 to descend through the operation table 3, the first motor 70 of the winding mechanism 7 is started synchronously to drive the winding roller 74 to rotate and wind the cable 8, at the same time, the cleaning assembly 76 can also be started, the pump of the liquid storage tank 770 pumps the cleaning liquid out and sprays it on the cable 8 through the spray head 773, then the second motor 780 drives the sponge block 778 to rotate and wipe the surface of the cable, so that the cable 8 is orderly wound while a complete cleaning and maintenance is completed, thereby realizing the combination of winding and cleaning, greatly improving the automation degree and maintenance convenience of the equipment.

[0083] The above descriptions are only the preferred embodiments of the present application, and are not intended to limit the present application. The present application can have various modifications and changes for those skilled in the art. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
