Description

Technical Field

[0001] The present invention relates to the technical field of urban road lighting and monitoring, and particularly relates to a split-type winding device and an integrated pole for monitoring and lighting. Background Art

[0002] With the continuous improvement of the construction of smart cities and the demand for security monitoring, monitoring poles with cameras and multi-functional poles integrating cameras and lighting fixtures have become an important part of urban infrastructure. Such devices are usually installed at the top of poles with a height of 6 - 15 meters. When maintaining the devices, troubleshooting, and upgrading functions, they face two major technical bottlenecks: First, traditional hydraulic / electric lifting mechanisms have defects such as strong power supply dependence and poor fault emergency response capabilities. For example, when encountering typhoon power outages or aging lines, maintenance personnel are forced to use aerial work platforms, and the single maintenance cost is as high as 5 - 8 times that of regular operations. Second, working on cameras requires working at heights, which poses risks of falling (statistics show that 68% of street lamp maintenance accidents are related to working at heights) and accidentally touching high-voltage lines, and there is also a probability of tools falling during the disassembly and assembly of the devices. Third, for areas with narrow roadway widths (old urban areas / parks / mountain roads, etc.), it is difficult for aerial work platforms to enter (the minimum deployment width of general aerial work platforms is 4.2 meters). Fourth, when an aerial work platform is operating, it is necessary to close the lane, resulting in additional traffic control costs. Summary of the Invention

Detailed implementation manners

[0038] The following specific embodiments illustrate the implementation manners of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0039] As Figure 1-7 shown, this embodiment provides a split type winding device 100, which includes a fixed plug-in commutation component 110 for installation inside the operation door of the pole body 210 and a moving plug-in winding component 120 for supporting use with the fixed plug-in commutation component 110.

[0040] The fixed plug-in reversing assembly 110 refers to a relatively fixed assembly that can be connected to the mobile plug-in winding assembly 120 by plugging, and can provide a reversing function for the wire rope. The fixed plug-in reversing assembly 110 includes a fixed plug-in tube 111 and a first fixed pulley 112 arranged on the fixed plug-in tube 111. Exemplarily, the fixed plug-in tube 111 is arranged horizontally, one end of which is welded or bolted to the cavity wall of the rod body 210, and the other end faces the door opening (after the operating door is opened, there is a door opening at the original position of the operating door), which is convenient for plugging and connecting with the mobile plug-in tube 121 of the mobile plug-in winding assembly 120. Exemplarily, the pulley frame of the first fixed pulley 112 is welded or bolted to the fixed plug-in tube 111, and the pulley is installed on the pulley frame through a rotating shaft.

[0041] The mobile plug-in winding assembly 120 refers to an assembly that can be carried (moved), can be connected to the fixed plug-in reversing assembly 110 by plugging, and can wind up the wire rope. The mobile plug-in winding assembly 120 includes a mobile plug-in tube 121, a gallows 122 arranged on the mobile plug-in tube 121, a drum 123 rotatably mounted on the gallows 122, a first wire rope 124 wound on the drum 123, a transmission unit mounted on the gallows 122, and a power input unit for driving the drum 123 to rotate through the transmission unit. One end of the mobile plug-in tube 121 is used for plug-in connection with the fixed plug-in tube 111. In order to prevent the gallows 122, the drum 123, the transmission unit, the power input unit, etc. from entering the door opening, the mobile plug-in tube 121 has a certain length, and the gallows 122, the drum 123, the transmission unit, the power input unit, etc. are located at the other end. The gallows 122 is fixed on the upper side of the movable plug tube 121, and can be fixed by welding or bolting; the gallows 122 is provided with a first rotating shaft for installing the drum 123; illustratively, the first rotating shaft is connected to the gallows 122 through a bearing and a bearing seat, so that the smoothness of the rotation of the first rotating shaft can be ensured. The drum 123 is sleeved on the first rotating shaft and rotates synchronously with the first rotating shaft (that is, a circumferential limit is provided, such as a flat key and other structures). The fixed end of the first steel wire rope 124 is fixed to the drum 123, the rope body of the first steel wire rope 124 is wound around the drum 123, and the free end of the first steel wire rope 124 is used to be detachably connected to the first end of the second steel wire rope 213 in the rod body 210. For easier use, the fixed plug-in tube 111 and the movable plug-in tube 121 should not be able to rotate along the axis after being plugged in, so they need to have circumferential limits; illustratively, the fixed plug-in tube 111 and the movable plug-in tube 121 are both square tubes, and the outer dimensions of one match the inner dimensions of the other, so that the plug-in connection can be ensured while avoiding rotation and shaking.

[0042] A split winding device 100 is used to replace the traditional winch, and only a fixed plug-in reversing component 110 is installed in the operating door, and the mobile plug-in winding component 120 is used as a portable tool; the fixed plug-in reversing component 110 includes a fixed plug-in tube 111 and a first fixed pulley 112, and the overall structure occupies a small space, which is convenient for later maintenance and repair; the mobile plug-in winding component 120 is used as a universal tool, and only a small amount is required, which can undoubtedly save more costs; and, since the first steel wire rope 124 is a component of the mobile plug-in winding component 120, the first steel wire rope 124 is also used as a common part, which saves the amount of steel wire rope and further reduces the cost.

[0043] In an optional solution of the present embodiment, the transmission unit includes a passive gear 1251 installed on the gallows 122 and rotating synchronously with the reel 123, a driving gear 1252 installed on the gallows 122 and meshing with the passive gear 1251, and a protective cover 1254 covering the driving gear 1252 and the passive gear 1251. Exemplarily, the passive gear 1251 is installed on the first rotating shaft and is circumferentially limited with the first rotating shaft in the form of a key connection. Exemplarily, a rotatable second rotating shaft (also called a gear shaft 1253) is installed on the gallows 122 through a bearing seat and a bearing, and the driving gear 1252 is installed on the gear shaft 1253. The two are circumferentially limited by a key connection or the two are formed as an integral structure. The power input unit drives the active gear 1252 to rotate forward / reverse, and drives the passive gear 1251 to rotate reverse / forward, so that the reel 123 rotates reverse / forward, and then the first wire rope 124 is retracted / released, so that the second wire rope 213 connected to the first wire rope 124 is retracted / released, so that the lamp 230, camera 240, etc. can be raised / lowered.

[0044] In an optional solution of this embodiment, the power input unit includes a crank 1261, one end of which is connected to the gear shaft 1253 of the driving gear 1252, and the other end is used for hand holding. Exemplarily, the crank 1261 includes a rocker arm and a handle, the ends of which are vertically connected (such as integrally formed or welded), and one end of the rocker arm is vertically connected to the shaft end of the gear shaft 1253 extending outside the gallows 122 (such as welded, bolted, pinned, etc.). The operator shakes the crank 1261 to rotate the gear shaft 1253, which synchronously drives the driving gear 1252 to rotate, thereby rotating the driven gear 1251, and then rotating the reel 123.

[0045] In an alternative embodiment of the present embodiment, the power input unit includes a handheld power tool 1262, and the power shaft of the handheld power tool 1262 is connected to the gear shaft 1253 of the driving gear 1252. In this embodiment, the gear shaft 1253 can be driven by both the crank 1261 and the handheld power tool 1262. Exemplarily, the crank 1261 and the handheld power tool 1262 are respectively connected to both ends of the gear shaft 1253. Exemplarily, the crank 1261 includes a crank arm, a handle, and a plug connector. One end of the crank arm is perpendicularly connected to one end of the handle, and one end of the plug connector is perpendicularly connected to the other end of the crank arm. The three can be welded together or connected by bolts. A plug-in groove adapted to the plug connector is provided at the shaft end of the gear shaft 1253 extending outside the gallows 122, so that the connection between the crank 1261 and the gear shaft 1253 is a detachable connection. When using the handheld power tool 1262 to drive the gear shaft 1253, the crank 1261 is removed to avoid the crank 1261 from injuring the operator; it should be noted that the plug connector and the plug-in groove are used for transmitting torque and necessarily have circumferential limitation. For example, the plug connector is a prism (triangular prism, quadrangular prism, hexagonal prism, etc.), and the plug-in groove is a groove adapted to the prism. Exemplarily, the handheld power tool 1262 is an electric hand drill, and its main body is fixed to the movable insertion pipe 121, for example, by a clip connection, and its output shaft is connected to the gear shaft 1253, for example, by welding or by a third shaft (connected to the gear shaft 1253 and the output shaft of the electric hand drill at both ends); alternatively, the electric hand drill is of a split design, and a plug connector is installed on its output shaft, and a plug-in groove is provided on the gear shaft 1253.

[0046] In an alternative embodiment of the present embodiment, the power input unit includes an electric motor, the electric motor is installed on the side of the movable insertion pipe 121, and the motor shaft of the electric motor is in transmission connection with the gear shaft 1253 of the driving gear 1252. Exemplarily, a driving pulley 1265 is installed on the motor shaft, a driven pulley is installed at one end of the gear shaft 1253, and a belt 1267 is hung between the driving pulley 1265 and the driven pulley; a protective cover 1254 is provided on the side where the driving pulley 1265, the driven pulley 1266, and the belt 1267 are provided to avoid injury. The electric motor is an AC motor 1263 powered by mains electricity or a DC brushless motor 1264 powered by a battery 1268. The AC motor 1263 comes with a plug, and the battery 1268 is installed on one side of the movable insertion pipe 121 and is electrically connected to the DC brushless motor 1264.

[0047] As Figure 1 、 2, as shown in FIGS. 8-14, this embodiment further provides a combined monitoring and lighting pole 200, which includes a pole body 210, a cross arm 220, a second fixed pulley 211, a third fixed pulley 212, a hook, a second steel wire rope 213, and the split reel device 100 of any of the above embodiments. The pole body 210 is a hollow pole, and an operable operation door is provided at the lower side of the pole body 210. The cross arm 220 is a hollow arm, and one end of the cross arm 220 is fixedly connected to the top or the side of the pole body 210 near the top. The interior of the cross arm 220 is communicated with the interior of the pole body 210. The second fixed pulley 211 is arranged inside the connection between the cross arm 220 and the pole body 210. A rope passing hole is provided at the lower part of the side of the cross arm 220 away from the pole body 210. The hook (which belongs to the prior art, see the following text) includes a fixed part and a movable part. The fixed part is installed below the rope passing hole of the cross arm 220, and the movable part is installed above the lamp 230 and / or the camera 240 (when a disc-shaped mounting bracket 250 or a rod-shaped mounting bracket 260 is provided, the movable part is installed on the disc-shaped mounting bracket 250 or the rod-shaped mounting bracket 260). The third fixed pulley 212 is arranged inside the cross arm 220 and on the side close to the pole body 210 of the rope passing hole. The first end of the second steel wire rope 213 is located at the operation door and is provided with a safety hook 214. The second end extends upward along the cavity inside the pole body 210, bypasses the second fixed pulley 211 and then enters the cavity of the cross arm 220, then bypasses the third fixed pulley 212, passes through the rope passing hole and passes through the central hole of the fixed part of the hook, and is connected to the movable part of the hook. It should be noted that the routing method of the second steel wire rope 213 and the installation of the second fixed pulley 211 and the third fixed pulley 212 are all prior arts and will not be described in detail.

[0048] In this embodiment, loop ends are respectively provided at the free end of the first steel wire rope 124 and the first end of the second steel wire rope 213, and the two loop ends are connected by the safety hook 214. In this way, it is convenient for both of them to be connected and it is also convenient to pass the free end of the first steel wire rope 124 through the first fixed pulley 112. Exemplarily, the loop end is formed by folding back the rope end and fixing it with a clip or the like.

[0049] During use, the movable insertion pipe 121 is inserted into the fixed insertion pipe 111. The second end (free end) of the first steel wire rope 124 passes through below the fixed pulley and then extends upward to be connected to the first end of the second steel wire rope 213. The first steel wire rope 124 is wound or released by the reel 123, so that the lamp 230 and / or the camera 240 connected to the second end of the second steel wire rope 213 is raised or lowered.

[0050] Due to the adoption of the split-type retracting device 100, during initial installation, first set up the pole, and then pay out the wire (which means connecting the first steel wire rope 124 and the second steel wire rope 213, and releasing the first steel wire rope 124 on the reel 123, so that the other end of the second steel wire rope 213 drops down), so as to operate the connection of the lamp 230 and / or the camera 240 with the second steel wire rope 213 on the ground. Finally, retract the first steel wire rope 124, so as to raise the lamp 230 and / or the camera 240 to the designated position. It should be noted that the second end of the second steel wire rope 213 is exposed below the cross arm 220, and it is necessary to limit it to prevent the second end from retracting into the pole body 210 or the cross arm 220 due to the self-weight of the second steel wire rope 213 during the process of setting up the pole; moreover, during the process of paying out the wire, it is necessary to use another tool to pull down the second end of the second steel wire rope 213. Exemplarily, a counterweight (such as the moving part of a hook) can be connected to the second end of the second steel wire rope 213 before setting up the pole, which can not only prevent the second steel wire rope 213 from retracting, but also facilitate the descent of the second end during wire pay-out.

[0051] In this embodiment, the lamp 230 and the camera 240 are powered or signal-transmitted in a wired or wireless manner. Wired means power supply or signal transmission through the composite cable 280, and wireless means power supply or signal transmission through the existing cableless point contact device 270 (prior art, see below). The integrated monitoring and lighting pole 200 further includes a disc-shaped mounting bracket 250 (also called a lamp disc) or a rod-shaped mounting bracket 260. The second end of the second steel wire rope 213 is connected to the disc-shaped mounting bracket 250 or the rod-shaped mounting bracket 260, and the lamp 230 or the camera 240 is fixed to the disc-shaped mounting bracket 250 or the rod-shaped mounting bracket 260. Similarly, the specific connection manner between the disc-shaped mounting bracket 250 (also called a lamp disc) or the rod-shaped mounting bracket 260 and the second steel wire rope 213, and the specific installation form of the lamp 230 or the camera 240 with respect to the disc-shaped mounting bracket 250 or the rod-shaped mounting bracket 260 are all prior art and not the key points of protection of this application, and will not be elaborated here. By providing the disc-shaped mounting bracket 250 or the rod-shaped mounting bracket 260, more lamps 230 or cameras 240 can be installed. It should be noted that the length and number of the cross arms 220 are determined according to the size of the disc-shaped mounting bracket 250 or the rod-shaped mounting bracket 260. Correspondingly, the number of the second steel wire ropes 213 may be multiple, so as to better lift the disc-shaped mounting bracket 250 or the rod-shaped mounting bracket 260. When there are multiple second steel wire ropes 213, the first ends of the multiple second steel wire ropes 213 can share the same rope loop, and the number and positions of the second fixed pulley 211 and the third fixed pulley 212 are adaptively set.

[0052] Preferably, the second end of the second steel wire rope 213 is connected to the lamp 230, the camera 240, the disc-shaped mounting bracket 250 or the rod-shaped mounting bracket 260 through a cable-free contact device 270 (i.e., a detachable special hook, which is divided into two parts. The fixed part is fixed on the lower side of the cross arm 220, and the moving part is fixed on the upper side of the lamp 230, the camera 240, the disc-shaped mounting bracket 250 or the rod-shaped mounting bracket 260. The two parts can be connected together after moving towards each other, and can be unlocked and separated after moving relative to each other again. When connected together, power supply can also be carried out. For example: hook cable docking device, hook plug power connection device, magnetic cable connection device or hook magnetic electric contact, etc.). Of course, other devices can also be used for connection. The specific connection method is not the key point of protection of this application, so it will not be elaborated here. Optionally, the hook adopts an automatic safety unloading device, and this device belongs to the hook for cable-lifting.

[0053] In this embodiment, the integrated monitoring and lighting pole 200 further includes a limit chain link 215 and a limit hook 216. The first end or a position near the first end of the second steel wire rope 213 is connected to the limit chain link 215. The limit hook 216 is arranged in the operation door with the hook tip facing downwards and is fixed to the cavity wall of the pole body 210. At least one link of the limit chain link 215 can be hooked on the limit hook 216. In this way, it can be avoided that the first end of the second steel wire rope 213 moves upwards due to some uncertain reasons during the pole erection process (after moving too high, it will be impossible to connect to the first steel wire rope 124); moreover, after the lamp 230 or the camera 240 is raised to the top, since the moving plug-in winding component 120 has been removed, the second steel wire rope 213 in the pole body 210 is in a natural drooping state at present. By setting the limit chain link 215 and the limit hook 216, the upward movement of the second steel wire rope 213 in the pole body 210 is prevented, thereby preventing the lamp 230 or the camera 240 from suddenly falling, playing a "double insurance" role (usually, after the lamp 230 or the camera 240 is raised to the top, it is connected to the cross arm 220 through the cable-free contact device 270).

[0054] Although the present invention has been described in detail above with general descriptions and specific embodiments, on the basis of the present invention, some modifications or improvements can be made, which are obvious to those skilled in the art. Therefore, these modifications or improvements made without departing from the spirit of the present invention all fall within the scope of protection required by the present invention.
