Description

Technical Field

[0001] The invention relates to the technical field of lighting devices and relates to a high pole lamp suspension device. Background Art

[0002] High pole lamps generally refer to lighting devices composed of steel conical lamp poles over 15 meters and high-power combined lamp stands. It consists of lamp holders, internal lamp electrical equipment, pole body and foundation. The shape of the lamp holder can be determined according to user requirements, surrounding environment and lighting needs; the internal lamps are mostly composed of floodlights and spotlights, and the light source is NG400 high-pressure sodium lamp, with a lighting radius of 60 meters. The pole body is generally a pyramidal single-body structure, made of rolled steel plates, with a height of 15-40 meters, and mostly composed of two or three sections.

[0003] Generally, it can be divided into lifting type and non-lifting type. The height of the lifting main pole is generally more than 18 meters, and the electric lifting operation is convenient. After the lamp panel is raised to the working position, it can automatically unhook and hook the lamp panel through the dovetail hook device to unload the wire rope, reduce the long-term stress on the wire rope, shorten its service life, and cause safety risks.

[0004] The lifting high pole lamp has a lifting component, which has two lifting control modes: manual and electric. The lamp panel can be safely and reliably lowered to 2.5 meters above the ground, which is convenient for maintenance. The length of the lead-out line of the manual remote control device is 10 meters. The operator remotely controls the lifting and lowering of the lamp panel at 5 meters, which can ensure the personal safety of the operator. The lifting high pole lamp is also equipped with a spare cable. When the lamp panel drops to the lowest position, one end of the cable is inserted into the socket of the electrical control system, and the other end is inserted into the junction box on the lamp panel. In this way, the lamp panel can be directly powered and the lamp can be repaired. The sealing level of all lamps of the lifting high pole lamp is IP65 international standard to prevent dust and rain from entering and ensure the service life of the bulb. The material of the lamp is generally made of aluminum alloy plate and stainless steel with good corrosion resistance.

[0005] The current dovetail hook devices and rotary hook systems have the problems of falling off, inaccurate hooking, difficulty in hooking, and the hook opening is downward, which makes it easy to slip and poses a high safety risk during actual maintenance. Summary of the invention

[0007] The technical solution of the present invention is achieved through the following measures: a high pole lamp suspension device, including a lamp pole body and a lamp panel arranged on the outer side of the upper part of the lamp pole body, and also including a limit plate, a fixing rod, a locking mechanism and an unlocking assembly. A plurality of limit plates are evenly spaced along the circumference of the outer side of the upper end of the lamp pole body, and each limit plate is provided with a limit groove that passes through from top to bottom and opens outward on the upper side, and a fixing rod is fixedly installed in each limit groove, and a limiting hole is formed between the fixing rod and the inner wall of the limit groove, and a locking mechanism is provided on the upper side of the lamp panel corresponding to each fixing rod position, and the locking mechanism includes a base, a limit rod, a mounting rod and a locking plate, and a base can be detachably fixedly installed on the upper side of the lamp panel corresponding to each limit groove position, and the upper side of the base is fixedly spaced from the inside to the outside. A limit rod and a mounting rod are fixedly installed, and the upper end of the limit rod is located above the limit plate after passing through the limit hole. A strip swing hole is provided in the middle of the limit rod, which passes through the diameter direction of the lamp pole body. A locking plate is provided on the upper side of the fixed rod, and the first end of the lock plate is located on the inner side of the upper part of the swing hole. The second end of the lock plate is fixedly installed with a flip plate hingedly installed with the upper part of the mounting rod. A lock hole is formed on the upper side of the base, the fixed rod, the limit rod and the lower side of the lock plate, and an unlocking component is rotatably installed on the lower part of the mounting rod corresponding to the position below the fixed rod, and the unlocking component causes the flip plate to rotate to open the lock hole after the lamp panel moves upward, and the lamp panel moves downward to close the lock hole after the flip plate rotates, and the lamp panel moves upward again to reopen the lock hole after the flip plate rotates.

[0008] The following are further optimizations and / or improvements to the above technical solutions: The above-mentioned turning plate may be in an arc shape with an opening facing upward.

[0009] The above-mentioned unlocking assembly may include a hinge plate and a detaching rod. The upper end of the fixing rod is provided with a mounting groove which opens upward and passes through along the diameter direction of the lamp pole body. The second end of the locking plate is hingedly installed on the inner side of the upper part of the mounting groove. A pair of hinged plates are fixed on the side of the mounting rod away from the lamp pole body. The hinged plate and the detaching rod in an inverted L shape are hingedly installed together.

[0010] The above-mentioned detachment rod may include a horizontal section and an inclined section, the horizontal section is arranged in a radial direction, the first end of the horizontal section is located on the inner side of the middle part of the swing hole, the second end of the horizontal section passes through the installation groove and is hingedly installed with the hinge plate, the lower part of the inclined section and the second end of the horizontal section are fixed together, the upper part of the inclined section is inclined outwardly relative to the lower part, and the side of the upper part of the inclined section close to the lamp pole body is in contact with the side of the flip plate away from the lamp pole body.

[0012] The first end of the horizontal section may be provided with a weight-reducing hole.

[0013] The present invention has a reasonable and compact structure. At the beginning, the fixing rod is located above the locking plate. Driven by the lifting assembly in the lamp pole body, when the lamp panel moves upward, it drives the base to move upward. When the lower side of the fixing rod contacts the upper side of the locking plate, the lamp panel continues to move upward, and the fixing rod blocks the locking plate, causing the flip plate to swing upward, and the lock hole is gradually opened. When the lamp panel continues to move upward, the lock plate and the fixing rod can be separated from each other. At this time, the first end of the lock plate swings in the opposite direction to the inner side of the upper part of the swing hole under the action of the flip plate, and the lock hole is closed. At this time, the lamp panel starts to move downward, and finally the upper side of the fixing rod contacts the lower side of the locking plate. The inner wall of the lock hole supports the fixing rod, so that the lamp panel no longer moves downward, thereby realizing safe suspension between the lamp panel and the lamp pole body. The present invention has the characteristics of safety, labor saving, simplicity and high efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0022] The present invention is not limited by the following embodiments, and specific implementation methods can be determined based on the technical solution of the present invention and actual conditions.

[0023] In the present invention, for the convenience of description, the relative position relationship of each component is described according to the attached Figure 1 The positional relationships such as front, back, top, bottom, left, and right are described according to the layout directions of the drawings in the specification.

[0024] The present invention will be further described below in conjunction with embodiments and drawings: Embodiment 1: As shown in the attached Figures 1 to 7 As shown, the high pole lamp suspension device includes a lamp pole body 1 and a lamp panel 2 arranged on the outer side of the upper part of the lamp pole body 1, and also includes a limit plate 3, a fixing rod 4, a locking mechanism and an unlocking component. A plurality of limit plates 3 are evenly spaced along the circumference of the outer side of the upper end of the lamp pole body 1, and each limit plate 3 is provided with a limit groove 5 which passes through from top to bottom and opens outward on the upper side. A fixing rod 4 is fixedly installed in each limit groove 5, and a limiting hole is formed on the inner wall of the fixing rod 4 and the limit groove 5. A locking mechanism is provided on the upper side of the lamp panel 2 corresponding to the position of each fixing rod 4. The locking mechanism includes a base 6, a limit rod 7, a mounting rod 17 and a locking plate 9. The base 6 is detachably fixedly installed on the upper side of the lamp panel 2 corresponding to the position of each limit groove 5. The limit rod 7 and the mounting rod 17 are fixedly installed on the upper side of the base 6 from the inside to the outside. The upper end of 7 passes through the limiting hole and is located above the limiting plate 3. The middle part of the limiting rod 7 is provided with a strip-shaped swinging hole 10 which passes through the diameter direction of the lamp pole body 1. A locking plate 9 is provided on the upper side of the fixing rod 4. The first end of the locking plate 9 is located on the inner side of the upper part of the swinging hole 10. The second end of the locking plate 9 is fixedly installed with a flip plate 8 which is hingedly installed with the upper part of the mounting rod 17. A lock hole 11 is formed on the upper side of the base 6, the mounting rod 17, the limiting rod 7 and the lower side of the locking plate 9. An unlocking component is rotatably installed on the lower part of the mounting rod 17 corresponding to the position below the fixing rod 4. The unlocking component opens the lock hole 11 after the flip plate 8 is rotated after the lamp panel 2 moves upward, closes the lock hole 11 after the flip plate 8 is rotated after the lamp panel 2 moves downward, and reopens the lock hole 11 after the flip plate 8 is rotated after the lamp panel 2 moves upward again.

[0025] According to the needs, the lamp pole body 1 is an existing well-known technology. There is a lifting assembly on the inner side of the lower part of the lamp pole body 1 to move the lamp panel 2 up and down. The upper ends of the limit rod 7 and the upper ends of the installation rod 17 are both chamfered, and the fixing rod 4 and the inner wall of the limit groove 5 form a limit hole that passes through from top to bottom. The upper side of the fixing rod 4 contacts with the lower side of the locking plate 9, and the inner wall of the locking hole 11 supports the fixing rod 4, so that the lamp panel 2 no longer moves downward, thereby realizing safe suspension between the lamp panel 2 and the lamp pole body 1.

[0026] When the lamp panel 2 needs to be lowered, the lamp panel 2 is first moved upward by the lifting assembly in the lamp pole body 1. When the fixing rod 4 contacts the upper side of the unlocking assembly 13, after the lamp panel 2 continues to move upward, the fixing rod 4 causes the unlocking assembly to drive the flip plate 8 to rotate, and the lock hole 11 is gradually opened. When the flip plate 8 swings 90 degrees, the lock hole 11 is fully opened, and then the lamp panel 2 starts to move downward. At this time, the horizontal section 13 swings and resets under the gravity of the inclined section 14. At the same time, the flip plate 8 continues to swing under the gravity. Finally, the flip plate 8 rotates and falls on the upper end of the limit rod 7, the lock hole 11 is closed, and the lamp panel 2 continues to descend, so that the fixing rod 4 moves relatively upward in the lock hole 11. When the fixing rod 4 moves to the lower side of the flip plate 8, the lamp panel 2 continues to move downward, the flip plate 8 swings and resets under the action of the fixing rod 4, the flip plate 8 first opens the lock hole 11, and then the lock plate 9 closes the lock hole 11 and resets, and then the lamp panel 2 can continue to descend through the lifting assembly in the lamp pole body 1. The invention has a reasonable and compact structure, is easy to use, and has the characteristics of safety, labor saving, simplicity and high efficiency.

[0027] The above-mentioned high pole lamp suspension device can be further optimized and / or improved according to actual needs: Embodiment 2: As an optimization of the above embodiment, as shown in the attached Figure 1 , 3 As shown in Figure 7, the flip plate 8 is in an arc shape with an opening upward. According to the needs, the flip plate 8 is integrally arranged with the lock plate 9. During use, through such an arrangement, the flip plate 8 can contact the upper end of the limit rod 7 after rotating upward, and the fixed rod 4 moves upward relative to the base 6 into the arc groove of the flip plate 8 and then continues to move upward to push the flip plate 8, so that the flip plate 8 is reset after swinging, and the lamp panel 2 can be safely suspended on the upper end of the lamp pole body 1 by moving the lamp panel 2 up and down, or it can be lowered to the lower part of the lamp pole body 1 after being unlocked for inspection and maintenance.

[0028] Embodiment 3: As an optimization of the above embodiment, as shown in the attached Figures 1 to 7 As shown, the unlocking assembly includes a hinge plate 12 and a detaching rod, the upper end of the mounting rod 17 is provided with a mounting groove which opens upward and passes through along the diameter direction of the lamp pole body 1, the second end of the lock plate 9 is hingedly installed on the inner side of the upper part of the mounting groove, and the side of the mounting rod 17 away from the lamp pole body 1 is fixed with a pair of hinged plates 12, the hinged plates 12 and the detaching rod in an inverted L shape are hingedly installed together, and the detaching rod includes a horizontal section 13 and an inclined section 14, the horizontal section 13 is arranged in a radial direction, the first end of the horizontal section 13 is located on the inner side of the middle part of the swing hole 10, the second end of the horizontal section 13 passes through the mounting groove and is hingedly installed together with the hinge plate 12, the lower part of the inclined section 14 and the second end of the horizontal section 13 are fixed together, the upper part of the inclined section 14 is inclined outwardly relative to the lower part, and the side of the upper part of the inclined section 14 close to the lamp pole body 1 is in contact with the side of the flip plate 8 away from the lamp pole body 1.

[0029] According to the requirements, the horizontal section 13 and the inclined section 14 are integrally arranged, and the connection between the horizontal section 13 and the inclined section 14 is smoothly transitioned. During use, the installation groove is arranged to facilitate the disassembly and assembly of the detachable rod and the lock plate 9. By arranging the hinge plate 12, it is convenient to install the horizontal section 13, and at the same time, the swing amplitude of the horizontal section 13 is increased. When in use, this can make it easier to reset the first end of the horizontal section 13 after swinging downward, preventing the occurrence of a jamming phenomenon that makes the flip plate 8 unable to flip and the lock hole 11 unable to open, making the action of the unlocking component more reliable, and the lock hole 11 can be opened so that the lamp panel 2 can move up and down.

[0030] Embodiment 4: As an optimization of the above embodiment, as shown in the attached Figure 1 , 3 As shown in FIGS. 7 and 8 , the unlocking assembly further includes a stop pin 15, and the stop pin 15 is fixedly installed in the swing hole 10, the lower outer side of which contacts the upper side of the first end of the horizontal section 13. During use, by providing the stop pin 15, the first end of the horizontal section 13 can be prevented from swinging upward under the action of the tilting section 14, resulting in the fixed rod 4 being unable to block the horizontal section 13 when the base 6 moves upward, so that the tilting section 14 swings and drives the flip plate 8 to rotate.

[0031] Embodiment 5: As an optimization of the above embodiment, as shown in the attached Figure 1 , 3 As shown in Figures 7 to 8, a weight-reducing hole 16 is provided at the first end of the horizontal section 13. During use, when the base 6 moves upward, the first end of the horizontal section 13 is blocked by the fixing rod 4 and swings downward. Through such a setting, the weight of the horizontal section 13 can be less than the weight of the inclined section 14. After the base 6 moves downward, the horizontal section 13 can be reset under the gravity of the inclined section 14, and the first end of the horizontal section 13 contacts the limit pin 15 after automatically resetting.

[0032] The above technical features constitute the embodiments of the present invention, which have strong adaptability and implementation effect. Non-essential technical features can be added or reduced according to actual needs to meet the requirements of different situations.

[0033] The usage process of the best embodiment of the present invention is as follows: at the beginning, the fixing rod 4 is located above the locking plate 9. Driven by the lifting assembly in the lamp pole body 1, when the lamp panel 2 moves upward, it drives the base 6 to move upward. When the lower side of the fixing rod 4 contacts the upper side of the locking plate 9, the lamp panel 2 continues to move upward, and the fixing rod 4 blocks the locking plate 9, so that the flip plate 8 swings upward, and the lock hole 11 is gradually opened. When the lamp panel 2 continues to move upward, the lock plate 9 and the fixing rod 4 can be separated from each other. At this time, the first end of the locking plate 9 swings in the opposite direction under the action of the flip plate 8 and swings to the inner side of the upper part of the swing hole 10, and the lock hole 11 is closed. At this time, the lamp panel 2 starts to move downward, and finally the upper side of the fixing rod 4 contacts the lower side of the locking plate. The inner wall of the lock hole 11 supports the fixing rod 4, so that the lamp panel 2 no longer moves downward, thereby realizing safe suspension between the lamp panel 2 and the lamp pole body 1.

[0034] When the lamp panel 2 needs to be lowered, the lamp panel 2 is first moved upward by the lifting assembly in the lamp pole body 1. When the fixing rod 4 contacts the upper side of the horizontal section 13, the lamp panel 2 continues to move upward, and the fixing rod 4 causes the first end of the horizontal section 13 to swing downward, driving the tilting section 14 to swing and push the flip plate 8 to swing upward, and the lock hole 11 is gradually opened. When the flip plate 8 rotates 90 degrees, the lock hole 11 is fully opened, and the lamp panel 2 continues to move upward. After the fixing rod 4 acts on the horizontal section 13, the rotation angle of the flip plate 8 is greater than 90 degrees, and then the lamp panel 2 starts to move downward. At this time, the horizontal section 13 The flip plate 8 swings and resets under the action of gravity of the inclined section 14, and the flip plate 8 continues to swing under the action of gravity. Finally, the flip plate 8 rotates and falls on the upper end of the limit rod 7, the lock hole 11 is closed, and the lamp panel 2 continues to descend, so that the fixed rod 4 moves upward relatively in the lock hole 11. When the fixed rod 4 moves to the lower side of the flip plate 8, the lamp panel 2 continues to move downward, and the flip plate 8 swings and resets under the action of the fixed rod 4. The flip plate 8 first opens the lock hole 11 and then the lock plate 9 closes the lock hole 11 and resets. Then the lamp panel 2 can continue to descend through the lifting assembly in the lamp pole body 1.
