Description

Technical Field

[0001] The present application relates to the technical field of high pole lamps, and in particular to a high pole lamp. Background Art

[0002] High pole lamps are widely used in airports, ports and other public places. Among them, lift-type high pole lamps have become the mainstream device for high pole lighting due to their advantages such as easy use and maintenance, low cost and short production time. A major problem in high pole lamp technology is the lifting system of the lamp panel. Designing and manufacturing a good lifting system and ensuring its normal operation is one of the key technologies of high pole lamps.

[0003] Most of the current mainstream lifting high pole lamps have complex lamp panel structures, requiring inner rings, guide hooks, brake systems and other devices to realize the lifting function of the lamp panel. However, when the lifting lamp panel relies on the brake guide wheel to move along the outer wall of the lamp pole, the path planning adaptability is insufficient due to the strong uncertainty of the guide wheel path, and the lamp panel will deflect, which is not conducive to its subsequent docking. At the same time, due to the more complex lamp panel structure, the load of the lamp panel increases, and its stability during use is poor, which needs to be improved. Utility Model Content

[0004] In order to improve the stability of the lamp panel during use, the present application provides a high pole lamp.

[0005] The present application provides a high pole lamp, which adopts the following technical solution:

[0006] A high pole lamp comprises a lamp holder assembly and a flexible lifting assembly arranged on the lamp holder assembly, the lamp holder assembly comprises a vertically arranged lamp pole body, a lamp stand slidably arranged on the lamp pole body and a plurality of lamps mounted on the lamp stand, the lamp pole body is a structure which is hollow inside and has a conical shape, and the lamp stand is slidably sleeved on the lamp pole body; the flexible lifting assembly comprises a winch arranged inside the lamp pole body and close to its lower end and a pulley frame arranged at the upper end of the lamp pole body, a steel wire rope is wound on the winch, the steel wire rope passes through the pulley frame and is fixed to the lamp stand, and the winch is used to control the lifting and lowering of the lamp stand on the lamp pole body; the lamp holder assembly is provided with a guide assembly for maintaining the stability of the lamp stand.

[0007] By adopting the above technical solution, in the process of controlling the lamp stand to rise and fall on the lamp pole body, the winch is started and the wire rope is gradually wound around the winch, thereby pulling the lamp stand to move along the lamp pole body, allowing the lamp stand to gradually rise to the upper end of the lamp pole body. When controlling the lifting of the lamp stand, the guide assembly can slide on the outer wall of the lamp pole body to maintain stability during the lifting process and prevent the lamp stand from shaking.

[0008] Optionally, the guide assembly includes a fixing rod fixed on the lamp frame and extending toward the lamp pole body, and a guide wheel is rotatably provided at the end of the fixing rod toward the lamp pole body, and the guide wheel is slidably provided on the circumferential surface of the lamp pole body.

[0009] By adopting the above technical solution, in order to avoid collision between the lamp stand and the lamp pole body, a fixed rod is provided on the lamp stand, and a guide wheel is fixed at the end of the fixed rod. The guide wheel is in sliding contact with the outer wall of the lamp pole body. When lifting, the guide wheel can roll and contact on the outer wall of the lamp pole body, thereby ensuring the stability of the lamp stand when lifting.

[0010] Optionally, a telescopic rod is slidably arranged on the fixed rod, and the guide wheel is rotatably arranged on the end of the telescopic rod. A guide spring is also arranged on the fixed rod, one end of the guide spring is fixed to the fixed rod, and the other end is fixed to the telescopic rod, so that the guide wheel is always pressed against the lamp pole body.

[0011] By adopting the above technical solution, since the lamp pole body is a conical structure, the distance between the guide wheel and the outer wall of the lamp pole body is not always the same. Through the guide spring set on the fixed rod, when the lamp stand is lowered, the telescopic rod compresses the guide spring, and when the lamp stand is raised, the guide spring compresses the telescopic rod, allowing the guide wheel at the end of the telescopic rod to roll and contact the outer wall of the lamp pole body.

[0012] Optionally, two groups of guide components are symmetrically arranged on the lamp frame, and the two groups of guide components are symmetrically arranged on both sides of the lamp pole body.

[0013] By adopting the above technical solution, the two sets of guide components symmetrically arranged outside the lamp pole body can ensure the stability of the lamp stand when the lamp stand is raised or lowered, and the two telescopic rods are clamped to the lamp pole body through the action of the two guide springs.

[0014] Optionally, a rigid lifting assembly is provided on the lamp holder assembly, which includes a rack fixed on the outer wall of the lamp pole body and arranged along its height direction, a driving gear rotatably arranged on the lamp holder, and a driving motor controlling the rotation of the driving gear, and the driving gear is meshed with the rack.

[0015] By adopting the above technical solution, when controlling the lifting of the lamp stand, the driving gear and the rack are rigidly connected, and the connection method between the two is more stable, which can withstand a larger load and the lifting process is more stable.

[0016] Optionally, the rigid lifting assembly further comprises a transmission member arranged on the lamp stand, the transmission member comprises a worm wheel and a worm which are rotatably arranged on the lamp stand and cooperate with each other, the worm wheel and the driving gear are coaxially arranged and move synchronously, and the driving motor controls the rotation of the worm.

[0017] By adopting the above technical solution, the cooperation between the worm wheel and the worm has a self-locking effect, and only the worm can drive the worm wheel to rotate, but not vice versa. When the worm drives the worm wheel and controls the rotation of the driving gear, if the lamp stand tends to fall, the worm wheel cannot control the rotation of the worm, so that the lamp stand will not fall, thereby ensuring the safety of the lamp stand equipment.

[0018] Optionally, two groups of the rigid lifting components are symmetrically arranged on both sides of the lamp pole body.

[0019] By adopting the above technical solution, the two sets of rigid lifting components arranged on the lamp stand can control the lamp stand to be lifted more stably and smoothly during the lifting process.

[0020] Optionally, a sliding assembly for controlling the horizontal movement of the rigid lifting assembly is provided on the lamp stand, the sliding assembly includes a fixed plate fixed on the lamp stand and a movable plate slidably arranged on the fixed plate, the driving gear, driving motor and transmission member are all installed on the movable plate, the movable plate slides toward the lamp pole body, a tensioning member is fixed on the movable plate, the tensioning member tightens the movable plate so that the driving gear is always engaged with the rack.

[0021] By adopting the above technical solution, since the lamp pole body is a conical structure, the driving gear and the rack may be disengaged during the lifting and lowering of the lamp stand. By setting up a sliding assembly, the movable plate can control the driving gear, worm wheel and worm to move toward the direction of the lamp pole body under the action of the tensioning member, so that the driving gear is always engaged with the rack.

[0022] Optionally, a tightening spring sheet is provided between the fixed plate and the movable plate, one end of the tightening spring sheet is fixed to the end of the fixed plate, and the other end is fixed to the movable plate, so that the movable plate moves toward the direction of the lamp pole body.

[0023] By adopting the above technical solution, the set tightening spring piece can play a backup role, allowing the tightening spring piece to abut against the moving plate and move toward the lamp pole body, playing a reinforcing role and reducing the probability of the driving gear and the rack being separated.

[0024] Optionally, the lamp stand is provided with an anti-dropping member for preventing the lamp stand from accidentally falling during lifting and lowering, and the anti-dropping member comprises an anti-dropping block rotatably arranged on the lamp stand, and an end of the anti-dropping block is plugged into a tooth groove of the rack.

[0025] By adopting the above technical solution, when the lamp stand is raised, the anti-dropping block can be engaged in the corresponding tooth groove. If the lamp stand tends to fall, the anti-dropping block does not rotate and is always engaged in the tooth groove.

[0026] In summary, the present application includes at least one of the following beneficial technical effects:

[0027] 1. During the lifting process of the lamp stand, the rigid lifting component and the flexible lifting component provided in the present application form a dual lifting system, which can allow the lamp stand to be stably lifted and lowered on the lamp pole body. The rigid lifting component has stable lifting when controlling the lifting of the lamp stand, and the gear coordination can withstand more loads. The flexible lifting component can allow the lamp stand to be lifted and lowered quickly. In addition, the flexible lifting component can play a protective role. When the rigid lifting component fails, the flexible lifting component can take over and prevent the lamp stand from falling. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0033] The following is combined with Figure 1-4 This application is described in further detail.

[0034] The embodiment of the present application discloses a high pole lamp.

[0035] Reference Figure 1A high pole lamp includes a lamp holder assembly 1, which includes a vertically arranged lamp pole body 11. The lamp pole body 11 is a hollow and conical structure. A ring-shaped lamp holder 12 is slidably sleeved on the lamp pole body 11. The lamp holder 12 can be vertically raised and lowered on the lamp pole body 11. A plurality of lamps 13 are fixed on the lamp holder 12 and are evenly distributed along the circumference of the ring-shaped lamp holder 12. In the embodiment of the present application, the lamps 13 used are: LED lamps 13, and the number and specifications of the lamps 13 are: 15*400W; during the process, the lamp holder 12 is located at the upper end of the pole body, and the lamps 13 provide lighting to the lower part.

[0036] Reference Figure 1 and Figure 2 A flexible lifting component 2 for controlling the vertical lifting of the lamp holder 12 is arranged on the lamp pole body 11, which includes a winch fixed inside the lamp pole body 11 and close to its lower end, and a plurality of pulley frames 21 fixed on the upper end of the lamp pole body, each pulley frame 21 is rotatably provided with a plurality of pulleys 22, and the pulley frame 21 extends outward from the upper end of the lamp pole body 11, and a steel wire rope 23 is wound on the winch, and the free end of the steel wire rope 23 passes upward from the upper end of the lamp pole body 11, and is wound around each pulley 22 on the pulley frame 21, and is finally fixed to the lamp holder 12. When it is necessary to control the lifting of the lamp holder 12, the winch is started, and under the action of the steel wire rope 23, the lamp holder 12 is vertically moved outside the lamp pole body 11.

[0037] Reference Figure 2 and Figure 3A rigid lifting component 3 is also provided outside the lamp pole body 11, which includes a rack 31 fixed on the outer wall of the lamp holder 12, the rack 31 extends along the height direction of the lamp pole body 11, and a driving gear 32 is rotatably provided on the lamp holder 12, the driving gear 32 is meshed with the rack 31, and a driving motor 33 is installed on the lamp holder 12, and the driving motor 33 can control the rotation of the driving gear 32; the rigid lifting component 3 also includes a transmission member provided on the lamp holder 12, the transmission member includes a worm gear 34 rotatably provided on the lamp holder 12, the worm gear 34 and the driving gear 32 are coaxially provided and fixed with the same rotating shaft, and a worm 35 is also rotatably provided on the lamp holder 12, the worm 35 is meshed with the worm gear 34, and the worm 35 is located below the worm gear 34, and the driving motor 33 is installed on the lamp holder 12. The machine 33 is located at one end of the worm 35 away from the lamp pole body 11, and the output shaft of the drive motor 33 is fixed to the end of the worm 35. Through the transmission parts set, when the driving gear 32 is controlled to rotate, the driving motor 33 drives the worm 35 to rotate, and drives the worm wheel 34 to rotate through the worm 35, and finally controls the driving gear 32 to rotate, so that the driving gear 32 moves on the rack 31, thereby controlling the lamp stand 12 to rise or fall; in the process of controlling the lifting and lowering of the lamp stand 12, through the cooperation of the worm wheel 34 and the worm 35, the transmission can only be transmitted in one direction. When the worm 35 controls the worm wheel 34 and the driving gear 32 to rotate, and the lamp stand 12 is raised, the worm 35 and the worm wheel 34 can be locked, so that the worm wheel 34 cannot control the rotation of the worm 35, which can prevent the lamp stand 12 from falling suddenly.

[0038] Reference Figure 2 and Figure 3 Two groups of rigid lifting components 3 are arranged on the lamp pole body 11, and the two groups of rigid lifting components 3 are symmetrically arranged on both sides of the lamp pole body 11. The two groups of rigid lifting components 3 can maintain the stability of the lamp holder 12 during the lifting process, and prevent the lamp holder 12 carrying the lamp 13 from shaking outside the lamp pole body 11 during the lifting process, so as to avoid the lamp 13 from hitting the lamp pole body 11; in the process of controlling the lifting of the lamp holder 12, the rigid lifting components 3 play a leading role, and the flexible lifting components 2 are for backup or protection. When the rigid lifting components 3 control the lifting of the lamp holder 12, the flexible lifting components 2 act synchronously. When the rigid lifting components 3 fail and the lamp holder 12 slides, the flexible lifting components 2 can tighten the lamp holder 12 to prevent it from falling.

[0039] Reference Figure 2 and Figure 3A pair of sliding components 4 for controlling the rigid lifting component 3 to move in the horizontal direction are also provided on the lamp frame 12. The sliding component 4 includes a fixed plate 41 fixed on the lamp frame 12. One end of the fixed plate 41 is fixed to the lamp frame 12, and the other end is extended toward the inner side of the lamp frame 12 and toward the lamp pole body 11. A moving plate 42 is slidably matched on the fixed plate 41. A pair of guide holes 43 are opened on the fixed plate 41. The length directions of the two guide holes 43 are parallel to each other and are arranged along the moving direction of the moving plate 42. A moving block 44 is fixed at each position, the moving block 44 is inserted into the guide hole 43, and is slidably engaged in the guide hole 43; the driving gear 32, the worm wheel 34 and the worm 35 are all rotatably set on the moving plate 42, and the driving motor 33 is fixed on the moving plate 42. Since the lamp pole body 11 is a conical structure, when the lamp holder 12 is in the process of lifting, the driving gear 32 and the rack 31 will have the problem of loose engagement. By setting the moving plate 42, the driving gear 32 is always firmly engaged with the rack 31, thereby improving the stability of the lamp holder 12 in the process of lifting.

[0040] Furthermore, the sliding assembly 4 also includes a tensioning member arranged on the movable plate 42. The tensioning member is a tensioning spring 45 in the embodiment of the present application. One end of the tensioning spring 45 is fixed to the movable plate 42, and the other end can be fixed to the movable plate 42 on the other side of the sliding assembly 4. Through the set tensioning spring 45, the two driving gears 32 can always be engaged with the rack 31; a plurality of tightening spring sheets 46 are arranged at the ends of the fixed plate 41 and the movable plate 42 that are away from the lamp pole body 11. The length direction of the tightening spring sheets 46 is the same as the moving direction of the movable plate 42. One end of the tightening spring sheets 46 is fixed to the fixed plate 41, and the other end is fixed to the movable plate 42. The set tightening spring sheets 46 can apply elastic force to the movable plate 42, so that it always moves in the direction of the lamp pole body 11, so that the driving gear 32 always engages with the rack 31.

[0041] Reference Figure 2 and Figure 3A guide assembly 5 is also provided on the lamp frame 12, which includes a fixed rod 51 fixed on the lamp frame 12, the fixed rod 51 extends toward the lamp pole body 11, and the length direction of the fixed rod 51 is perpendicular to the moving direction of the moving plate 42, and a telescopic rod 52 is slidably provided at the end of the fixed rod 51 toward the lamp pole body 11, the fixed rod 51 is an internally hollow structure, and the end of the telescopic rod 52 is slidably inserted into the fixed rod 51, and a guide wheel 53 is rotatably provided at the end of the telescopic rod 52 toward the lamp pole body 11, and a guide wheel 53 is provided on the side of the lamp pole body 11 along the lamp pole body 1 A guide groove 54 is arranged in the height direction, and the guide wheel 53 is slidably fitted in the guide groove 54. A guide spring is arranged inside the fixing rod 51, and one end of the guide spring is fixed to the fixing rod 51, and the other end is fixed to the end of the telescopic rod 52. In the initial state, the guide spring presses against the telescopic rod 52, so that the guide wheel 53 is always slidably arranged in the guide groove 54. When the lamp stand 12 is in the process of lifting and lowering, the guide wheel 53 is always slidably fitted in the guide groove 54, so that the stability of the lamp stand 12 in the process of lifting and lowering is maintained, and the lamp stand 12 is prevented from shaking during the lifting and lowering process due to the influence of external wind force.

[0042] Reference Figure 2 and Figure 3 Two groups of guide components 5 are symmetrically arranged on the lamp holder 12, and the two groups of guide components 5 are symmetrically arranged on both sides of the lamp pole body 11. The length direction of the two fixed rods 51 on the two groups of guide components 5 is perpendicular to the moving direction of the two movable plates 42. Therefore, when the tensioning spring 45 is set, the end of the tensioning spring 45 away from the movable plate 42 can be fixed to the outer wall of the fixed rod 51 to avoid hard friction between the tensioning spring 45 and the outer wall of the lamp pole body 11; a pair of guide grooves 54 are symmetrically opened on the side wall of the lamp pole body 11. During the lifting and lowering process of the lamp holder 12, the two groups of guide components 5 are set to ensure the stability of the lifting and lowering of the lamp holder 12, and at the same time prevent the driving gear 32 and the rack 31 from disengaging during the lifting and lowering process.

[0043] Reference Figure 3 and Figure 4, an anti-dropping member 6 is also provided on the lamp holder 12 to prevent the lamp holder 12 from accidentally falling. The anti-dropping member 6 includes an anti-dropping block 61 rotatably arranged at one end of the movable plate 42 toward the lamp pole body 11. The anti-dropping block 61 is L-shaped and consists of a vertical block 611 and a horizontal block 612. The rotation point of the anti-dropping block 61 is located at the position where the vertical block 611 and the horizontal block 612 are connected. The end of the horizontal block 612 away from the vertical block 611 is plugged into the tooth groove of the rack 31. The vertical block 611 is vertically arranged, and the weight of the vertical block 611 is greater than the weight of the horizontal block 612. Under the action of the vertical block 611, it always maintains a vertical arrangement, so that the horizontal block 612 maintains a horizontal state. An anti-dropping plate 62 is fixed at the end of the movable plate 42 toward the lamp pole body 11. The anti-dropping plate 62 is located between the vertical block 611 and the lamp pole body 11, and when the vertical plate is in a vertical state, the anti-dropping plate 62 The release plate 62 fits with the vertical block 611. During the raising process of the lamp stand 12, the anti-stripping block 61 rotates freely. When the lamp stand 12 stops rising, the horizontal block 612 is snapped into the corresponding tooth groove. When the lamp stand 12 falls accidentally, the horizontal block 612 and the vertical block 611 tend to rotate clockwise. Since the anti-stripping plate 62 blocks the rotation of the vertical block 611, the horizontal block 612 is always snapped into the tooth groove, which can avoid the problem of the lamp stand 12 falling and allow the lamp stand 12 to be firmly fixed on the main body of the lamp stand 12; energized magnetic pole pieces 63 are fixed on the opposite surfaces of the anti-stripping plate 62 and the vertical block 611. After being energized, the two magnetic pole pieces 63 will produce the same polarity, allowing the vertical block 611 and the horizontal block 612 to rotate counterclockwise, allowing the end of the horizontal block 612 to fall out of the tooth groove, so that the lamp stand 12 can be smoothly lowered.

[0044] The implementation principle of a high pole lamp in an embodiment of the present application is: in the process of controlling the upgrading of the lamp holder 12, the driving motor 33 drives the worm 35 and the worm wheel 34 to rotate, thereby controlling the driving gear 32 to rotate, allowing the driving gear 32 to move along the rack 31, and controlling the lamp holder 12 to move on the lamp pole body 11, so as to achieve the purpose of lifting and lowering the lamp holder 12. In the process of lifting and lowering the lamp holder 12, the guide assembly 5 can be slidably set on the outside of the lamp pole body 11 to maintain the stability of the lamp holder 12 during the lifting and lowering process, and the anti-slip component 6 can prevent the lamp holder 12 from falling from the upper end of the lamp pole body 11.

[0045] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
