Description

Technical Field

[0001] The utility model relates to the technical field of lamp tray assembly and disassembly of high pole lamps, in particular to an unloading device for a sleeve-type lamp tray of a lifting high pole lamp. Background Art

[0002] Liftable high pole lights are a set of lighting equipment widely used in ports, airports, squares with large-area lighting needs, and urban overpasses. According to the relevant regulations of the Ministry of Transport and the Civil Aviation Administration of China on the manufacture and use of liftable high pole lights, the lamp panel must be firmly suspended on the lamp head after it rises to the working height, so that the lifting wire rope is in a relaxed state. When the lamp panel needs to be lowered to the ground for maintenance, the lamp panel can be smoothly separated from the lamp head.

[0003] Therefore, many hook devices for unloading lift-type high pole lamp panels have appeared in the field over the years, but the disadvantages are "difficult to hook" and "difficult to remove the hook". In windy weather, the lamp panel cannot be lifted or lowered. For this reason, there have been many accidents across the country where lamp panels fell from high altitudes during the process of unhooking the hooks when unloading the lamp panels, causing casualties. The reason is that the hooks installed on the lamp panel and the hook racks hanging on the lamp heads rely entirely on blind collisions in a free state to complete the hooking action. Because when the lamp panel rises to approach the three hook racks hanging on the lamp head, it may be difficult to align the three hooks installed on the lamp panel with the hook racks hanging on the lamp head due to the shaking of the lamp panel or the unevenness of the lamp panel, and it may be affected by the wind. It cannot ensure that the unified removal and hooking actions are completed at the same time, which causes the phenomenon of "difficult to hook" and "difficult to remove the hook". Utility Model Content

[0004] In view of the above technical problems, an unloading device for a sleeve-type lamp panel of a lifting high pole lamp is provided.

[0005] The technical means adopted by the utility model are as follows:

[0006] An unloading device for a sleeve-type lamp panel of a lifting high-pole lamp comprises a plurality of sleeve rods and sleeves matched with the sleeve rods; the bottom ends of the sleeve rods are mounted on the lamp panel and are rotatably connected with the lamp panel; the top end of the sleeve is fixedly connected with the lamp holder;

[0007] The outer wall of the sleeve rod near the top thereof is provided with at least two forks evenly distributed around the sleeve rod;

[0008] A first guide structure is fixed to the lower inner wall of the sleeve, and a second guide structure matching the first guide structure is installed on the upper inner wall of the sleeve;

[0009] The first guide structure includes arc-shaped structures whose number matches the number of the forks, and the multiple structures are evenly distributed around the inner wall of the sleeve, and the vertical gap between two adjacent structures forms an inlet and outlet channel for the forks to enter and exit the sleeve. The middle of the structure has a hook groove, and the top of the structure is an inclined first inclined guide surface. The first inclined guide surface is used for driving the forks to rotate and descend into the hook groove or the inlet and outlet channel when the lifting device drives the lamp panel to descend. After the forks fall on the first inclined guide surface, the first inclined guide surface is used to drive the forks to rotate and descend into the hook groove or the inlet and outlet channel;

[0010] The bottom of the second guide structure is evenly distributed with second inclined guide slopes around the axis of the sleeve, the number of which is twice the number of the structure, wherein a part of the second inclined guide slopes is located above the entry and exit channel, and the remaining part of the second inclined guide slopes is located above the hook groove; the second inclined guide slope is used for driving the sleeve rod and the fork to rotate after the fork touches the second inclined guide slope when the lifting device drives the lamp panel to rise.

[0011] Preferably, the lifting device includes a lifting wire rope, one end of which is fixedly connected to the lamp panel, and the other end passes through the center of the sleeve rod and the center of the sleeve, and is connected to the lifting wire main rope in the lamp pole after changing direction through the pulley group in the lamp head, and the lifting wire main rope is connected to the driving mechanism.

[0012] Preferably, the bottom end of the sleeve rod is connected to the lamp panel via a sleeve rod seat, the sleeve rod seat is fixed on the lamp panel, and the bottom end of the sleeve rod is rotatably connected to the sleeve rod.

[0013] Preferably, the bottom of the structure has a third inclined guide surface, and the third inclined guide surface is used for the fork to touch the third inclined guide surface during the rising process, and then the fork rotates under the action of the third inclined guide surface to enter the entry and exit channel.

[0014] Preferably, the second guide structure includes a horizontally arranged center plate, a plurality of evenly distributed arc plates are fixed to the bottom of the center plate, the number of the arc plates is twice the number of the structures, the second inclined guide slope is located at the bottom of the arc plate, and a downward-opening limit groove is formed between two adjacent arc plates.

[0015] Preferably, the second guide structure is detachably connected to the sleeve.

[0016] Preferably, an observation plate is fixed on the lower outer wall of the sleeve rod.

[0017] Preferably, the first inclined guide surface, the second inclined guide slope and the third inclined guide surface are curved guide surfaces.

[0018] When hooking, the driving mechanism drives the lifting wire main rope to work, drives the lifting wire rope upward, and then makes the lamp panel and the sleeve rod move upward. When the sleeve rod enters the sleeve, the fork contacts the third inclined guide surface, causing the fork (sleeve rod) to rotate and rise, so that the fork can smoothly enter the entry and exit channel. After that, the fork rises vertically along the vertically arranged entry and exit channel and touches the second inclined guide surface. Because the fork is still subjected to upward pulling force at this time, the fork can be rotated and lifted upward under the action of the second inclined guide surface until it enters the limit groove. At this time, the driving mechanism works in reverse to make the fork (sleeve rod) descend. At this time, the fork falls on the first inclined guide surface and rotates downward along the first inclined guide surface until the fork falls into the hook groove, completing the hooking. At this time, the lifting wire rope is in a relaxed state. Through the setting of the observation board, it can be intuitively observed whether the hooking is completed.

[0019] When unhooking (at this time the fork is in the hook slot), the lifting device drives the fork to move upward, disengage from the hook slot, then touches the second inclined guide surface, and rotates and rises under the action of the second inclined guide surface until it falls into another limit slot. Then the lifting device drives the fork to descend, and the fork falls on the first inclined guide surface, and rotates downward under the action of the first inclined guide surface until the fork falls into the entry and exit channel. Then the lifting device continues to descend, completing the separation of the sleeve rod and the sleeve, and realizing the unhooking operation.

[0021] 1. The utility model provides an unloading device for a lifting high pole lamp sleeve type lamp panel, which adopts the mutual cooperation of the sleeve rod and the sleeve, and can make the hooking and unhooking operations simpler and more convenient.

DETAILED DESCRIPTION

[0030] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments of the present invention can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0031] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means a limitation on the utility model and its application or use. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0032] like Figures 1 to 4As shown, this specific embodiment discloses an unloading device for a lifting high pole lamp sleeve lamp panel, comprising three sleeve rods 6 and three sleeves 4 matched with the sleeve rods 6; the bottom end of the sleeve rod 6 is rotatably connected to the sleeve rod seat 7 fixed on the lamp panel 8; the top end of the sleeve 4 is fixedly connected to the lamp head 2; the three sleeve rods 6 are evenly distributed around the axis of the lamp panel 8, so as to realize three-point force of the lamp panel 8 and better ensure the stable lifting of the lamp panel 8. The lifting device is used to drive the lamp panel 8 to lift and lower, and the lifting device comprises a lifting wire main rope and three lifting wire ropes 5 fixed to the lifting wire main rope. The three lifting wire ropes 5 are installed in the same way, that is, one end is fixedly connected to the lamp panel 8, and the other end passes through the center of the sleeve rod seat 7, the center of the sleeve rod 6, and the center of the sleeve 4, and is fixed to the lifting wire main rope arranged in the rod body 1 after changing direction through the pulley block 3. The lifting wire main rope is connected to the driving mechanism, and the driving mechanism is a conventional driving mechanism, such as a winch or a forward and reverse servo motor connected to a drum or other structure through a coupling, which will not be described in detail.

[0033] The sleeve rod 6 has at least two symmetrically arranged forks 61 on its outer wall near the top, and the forks 61 extend horizontally outward; this specific embodiment adopts two forks 61, so the number of the corresponding structures 41 mentioned later is also two, and the number of the second inclined guide slopes 44 is four.

[0034] The first guide structure is fixed to the lower inner wall of the sleeve 4, and the second guide structure 9 matched with the first guide structure is installed on the upper inner wall of the sleeve 4; the second guide structure 9 and the sleeve 4 can be a separate structure or an integrated structure, but when an integrated structure is adopted, it is difficult to make the sleeve 4, the first guide structure and the second guide structure 9 as a whole through a mold, so this specific embodiment adopts the second guide structure 9 and the sleeve 4 as a separate structure, which can be detachably connected. The first guide structure and the sleeve 4 are an integrated structure.

[0035] The first guide structure includes two arc-shaped structures 41, the two structures 41 are centrally symmetrical around the axis of the sleeve 4, and the vertical gap between the adjacent ends of the two structures 41 forms an inlet and outlet channel 42 for the fork 61 to enter and exit the sleeve 4. The middle of the structure 41 has a hook groove 43, and the two hook grooves 43 and the two inlet and outlet channels 42 are distributed in a cross shape. The top of the structure 41 is an inclined first inclined guide surface 44, and the first inclined guide surface 44 is used for the process of the lifting device driving the lamp panel 8 to descend, when the fork 61 falls on the first inclined guide surface 44, the fork 61 is driven to rotate and descend into the hook groove 43 or the in-and-out channel 42; the first inclined guide surface 44 is provided with a limit protrusion 45 extending upward at the hook groove 43, the limit protrusion 45 is close to the hook groove 43 and is located at an end slightly lower than the top side wall of the hook groove 43, and the limit protrusion 45 is an arc-shaped protrusion, so that when the fork 61 moves to the hook groove 43, it will not pass through the hook groove 43 quickly due to inertia and not fall into the hook groove 43, and the limit protrusion 45 can block the fork 61 when it moves to the hook groove 43 and then smoothly fall into the hook groove 43. The bottom of the structure has a third inclined guide surface 46, and the third inclined guide surface 46 is used in the process of the fork 61 ascending. After the fork 61 touches the third inclined guide surface 46, it rotates under the action of the third inclined guide surface 46, so that the fork 61 can smoothly enter the in-and-out channel 42.

[0036] The second guide structure 9 includes a center plate 91, the center of the center plate 91 has a through hole, and the bottom of the center plate 91 has four evenly distributed arc plates 94. The bottom of the arc plate 94 is a second inclined guide slope 92, of which two oppositely arranged second inclined guide slopes 92 are located above the inlet and outlet passage 42, and the other two oppositely arranged second inclined guide slopes 92 are located above the hook groove 43; the second inclined guide slope 92 is used for driving the sleeve rod 6 and the fork 61 to rotate after the fork 61 touches the second inclined guide slope 92 during the process of the lifting device driving the lamp panel 8 to rise. A limit groove 93 with an opening facing downward and extending upward is formed between two adjacent arc plates 94.

[0037] An observation plate (not shown) is fixed on the lower outer wall of the sleeve rod 6, so that the operator can observe the rotation angle of the sleeve rod 6 from below. The observation plate can be made of steel and painted with a color that is easy to observe, such as red, so that the operator can observe the observation disk from below, and then can intuitively see the rotation of the sleeve rod 6.

[0038] The first inclined guide surface 44 , the second inclined guide slope 92 , and the third inclined guide surface 46 are curved guide surfaces.

[0039] When hooking, the driving mechanism drives the lifting wire main rope to work, drives the lifting wire rope 5 to pull upward, and then the lamp panel 8 and the sleeve rod 6 move upward. When the sleeve rod 6 enters the sleeve 4, the fork 61 contacts the third inclined guide surface 46, so that the fork 46 (sleeve rod 6) rotates and rises, so that the fork 46 can smoothly enter the entrance and exit channel 42. After that, the fork 61 rises vertically along the vertically arranged entrance and exit channel 42 and touches the middle part of the second inclined guide slope 92. Because the fork 61 is still subjected to an upward pulling force at this time, the fork 61 can be under the action of the second inclined guide slope 92. While lifting upward, it rotates 45° in the clockwise direction and enters the limit groove 93. Then the driving mechanism works in reverse to lower the fork 61 (sleeve rod 6). At this time, the fork 61 falls on the middle part of the first inclined guide surface 44 (the upper part of the hook groove 43), and continues to rotate 45° in the clockwise direction while descending along the first inclined guide surface 44 and falls into the hook groove 43, completing the hooking. At this time, the lifting wire rope 5 is in a relaxed state. Through the above work, the fork 61 rotates 90° compared to when entering the entry and exit channel, and the observation board can intuitively observe whether the hooking is completed.

[0040] When unhooking (at this time the fork 61 is in the hook slot 43), the lifting device drives the fork 61 to move upward, disengage from the hook slot 43, and then touches another second inclined guide slope 92, and while rising under the action of the second inclined guide slope 92, it rotates 45° in the clockwise direction and falls into another limiting groove 93. Then the lifting device drives the fork 61 to descend, and the fork 61 falls on the middle part of the first inclined guide surface 44 (the lower part of the hook slot 43), and while moving downward under the action of the first inclined guide surface 44, it rotates 45° in the clockwise direction and falls into the entry and exit channel 42. Then the lifting device continues to descend, completing the separation of the sleeve rod 6 and the sleeve 4, and realizing the unhooking operation.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
