Description

Technical field:

[0002] The utility model relates to a mounting structure of an electrical device used at a high place, in particular to a portable mounting and disassembly component structure. Background technology:

[0004] The replacement of high-altitude equipment such as various lamps, radar testers, cameras, fire temperature sensors, high-voltage live devices, etc. is mainly carried out by setting up scaffolding or lifting vehicles. When these devices are installed at high altitudes, installation and disassembly require a lot of time.

[0005] Some products have a winch installed on the base. When replacement is needed, the winch controls the chain to lower the equipment to the ground for replacement.

[0006] In addition, the existing technology uses a magnetic lamp, which has a split structure (including upper and lower parts). The upper lamp holder is first installed on the wooden ceiling, and the lower part is the lamp. During installation, the lamp is adsorbed on the top by the suction of the magnet to achieve installation. Manual disassembly is required during disassembly.

[0007] The upper and lower split structures are combined together by the suction of magnets, which enables live installation in low-lying areas (within 2 meters from the ground); but if the lamp is dismantled at a high position (more than 2 meters from the ground), it is difficult to dismantle because the hands cannot touch the lamp and it has magnetic force, so it is only used in low-altitude areas.

[0008] However, for many electrical equipment or components, the installation height is 3-8 meters, so the structure using magnetic suction is not suitable, and it is also troublesome and time-consuming to use climbing equipment.

[0009] At present, a Chinese patent "Pan-tilt equipment compartment replacement system, operation method and disassembly mechanism thereof" has been retrieved, with publication number CN115084946A, which relates to the technical field of monitoring equipment. The first component is movably connected with the second component. When the first component and the second component are connected, the first plug-in and the second plug-in cooperate with each other, and the signal is turned on; when the first component and the second component are separated, the first plug-in and the second plug-in are separated from each other, and the signal is disconnected; the first component is connected to the pan-tilt main body, and the second component is connected to the equipment compartment. When the equipment compartment needs to be replaced, the first component and the second component are separated, and the new second component and the second plug-in are replaced, without replacing the first component and the first plug-in. Although the equipment compartment can be conveniently disassembled and assembled, and quickly replaced according to user needs, the high cost brought by the user's second purchase of the pan-tilt main body is avoided; but when it is replaced, the second component is manually contacted and rotated, so that the guide block is screwed into the guide groove, so that the second component is fixed relative to the first component, but when the installation component is located at a high place, this patent still requires manual disassembly and assembly, which adds trouble to the disassembly and assembly. Summary of the invention:

[0011] In view of the above problems, the purpose of the present utility model is to provide a portable installation and disassembly component structure, which is reasonably designed and can facilitate the installation and disassembly of high-position equipment.

[0015] Support device: It is used to connect with a support rod, and the upper end surface has a receiving bin for supporting the high-altitude equipment. After the support device supports the high-altitude equipment, when a force is applied to the support device, the high-altitude equipment also applies a force to the lock component at the same time, so that the lock component is in the locking position or the unlocking position.

[0016] Preferably, the above lock component includes at least two elastic sliders that can radially expand and contract at the cover opening of the fixed seat. The free end of the elastic slider cooperates with the limit groove for limiting. When the elastic slider extends, the free end of the elastic slider extends into the limit groove to relatively fix the high-altitude equipment and the fixed seat; when the elastic slider retracts, the free end of the elastic slider disengages from the limit groove, and the high-altitude equipment can relatively separate from the fixed seat due to gravity.

[0017] Preferably, the above elastic slider slides in the slideway of the fixed seat. A compression spring for driving the elastic slider to move deeper into the limit groove is provided between the fixed seat and the elastic slider. The first end of the elastic slider is connected to a rigid pulling rope, and the second end of the rigid pulling rope is connected to a lifting seat. The lifting seat has a first position for pulling the rigid pulling rope to retract the elastic slider and a second position for relaxing the rigid pulling rope to extend the elastic slider. The first position of the lifting seat corresponds to the unlocking position of the lock component, and the second position of the lifting seat corresponds to the locking position of the lock component.

When the lifting seat is in the first working position, the convex column is limited at the first limiting point position of the polygonal channel. When the lifting seat is in the second working position, the convex column is limited at the second limiting point position of the polygonal channel.

[0019] Preferably, four axial limiting channels are provided on the periphery of the above-mentioned cover-shaped seat, four rod bodies extending out of the limiting channels are provided on the lifting seat, and four elastically slidable blocks capable of radially expanding and contracting are provided at the cover opening of the fixed seat. The first ends of rigid pulling ropes are respectively connected to the elastic sliding blocks, and the second ends of the rigid pulling ropes are connected to the ends of the rod bodies; a top column capable of being pushed by the upper part of the high-altitude equipment is provided at the lower part of the lifting seat. After the high-altitude equipment is axially stressed by the supporting device, the top column and the lifting seat are pushed. After the first push, the lifting seat is in the first working position, and after the second push, the lifting seat is in the second working position; the rigid pulling ropes are limited and guided by a plurality of fixed pulleys.

[0020] Preferably, the above-mentioned supporting device includes a locking bracket and a receiving bin, and a buffer pad is provided on the receiving bin.

[0021] Preferably, a power supply inlet port, a power supply step-down module and a first contact terminal are provided on the body of the above-mentioned fixed base. The first contact terminal is a power supply point. The first contact terminal is a circular conductive sheet, which includes an arc-shaped live wire conductive sheet, a neutral wire conductive sheet and an insulator located between the ends of the live wire conductive sheet and the neutral wire conductive sheet. The insulator can separate the live wire conductive sheet and the neutral wire conductive sheet.

[0022] Preferably, the above-mentioned limiting groove is a circular groove provided on the high-altitude equipment. A second contact terminal capable of making electrical contact with the first contact terminal is provided on the outer surface of the high-altitude equipment above the circular groove.

[0023] Preferably, a fault indicator light is provided on the outer peripheral side of the high-altitude equipment between the second contact terminal and the electrical components inside the high-altitude equipment. The fault indicator light is connected in parallel with a voltage comparator across both ends of the vulnerable part in the electrical components; when the vulnerable part is damaged, the voltage comparator connected in parallel with the vulnerable part can convert the analog signal into a high level. At this time, the fault indicator light is on. The fault indicator light is provided on the outer peripheral side of the high-altitude equipment, which is convenient for observing whether the vulnerable part is damaged.

[0024] Preferably, a third contact terminal and a fourth contact terminal are respectively provided on the lower end surface of the lifting seat and the upper end surface of the bottom plate of the cover-shaped seat.

[0025] The voltage comparator (a commercially available component, model LM393) is connected in parallel with the vulnerable part. That is, the voltage comparator LM393 can only operate when the device is powered on. When it does not operate, the fault indicator light does not light up, which can ensure that there is no false alarm in the power-off state.

[0026] The operation mechanism of the voltage comparator LM393 when powered on: When the 3rd pin Ui1+ of the voltage comparator LM393 is greater than the 2nd pin Ui1-, Uo1 = 1, that is, high level, and the fault light is on; when the 3rd pin Ui1+ is less than the 2nd pin Ui1-, Uo = 0, that is, low level, and the fault light is off; set Ui1+ to 50% of the input voltage 24V of the vulnerable part 206, which is 12V, and Ui1- is the measured voltage at the output end of the vulnerable part 206. When Ui1- is less than 12V, that is, when Ui+>Ui-, Uo1 = 1, that is, high level, and the fault light is on; conversely, when Ui1- is greater than 12V, the fault light is off.

[0027] Advantages of the present utility model:

In particular, the installation of high-altitude equipment below 10 meters can be completed with the help of a telescopic support rod, and the length of the support rod can be selected according to the installation height of the high-altitude equipment.

[0029] 2. This application uses machinery to achieve disassembly and assembly, eliminating a large number of electronic components and not setting a storage battery, greatly increasing the reliability of the component; there is no need to consider the problem of inconvenience in installation and removal caused by long-term power outage.

[0031] 4. The replacement of the high-altitude equipment 2 no longer requires manual disconnection and connection of wires, nor does it require hand contact with the equipment for disconnection, connection and installation. Only by using the method of lifting with a support rod can the replacement of the high-altitude equipment 2 be quickly realized, saving a lot of working time.

[0032] 5. By observing the lighting status of the fault indicator light 203 of the aerial equipment 2, it is possible to quickly determine whether the vulnerable part 206 is damaged, facilitating rapid and accurate maintenance and replacement. Brief Description of the Drawings:

[0052] The present utility model will be further described below in conjunction with the accompanying drawings and specific implementation manners.

[0053] The portable installation and disassembly component structure of the present utility model includes a fixed seat 1, an aerial device 2, and a support device 3.

[0054] Among them, the fixed seat 1 is arranged on a pole tower, a wall, a roof, a high-voltage device, etc. Openings can be made on both sides or the top of the fixed seat 1 body, and it can be locked in a certain position by screws to meet the installation requirements of various angles and positions; a lock component with a locking station and an unlocking station is provided on the fixed seat 1.

[0055] The aerial device 2 can be a lamp, a radar tester, a camera, a fire temperature sensor, a live device, etc. A limit groove 201 capable of cooperating with the lock component to relatively fix and relatively disengage the aerial device 2 and the fixed seat 1 is provided on the aerial device 2.

[0056] The support device 3 includes a lock object bracket 301 and a receiving bin 302 arranged in the lock object bracket 301. The receiving bin 302 is in a groove shape, and a buffer pad 303 is provided in the receiving bin 302.

[0057] The support device 3 is used to connect with a support rod 5 (it can be fixedly connected or connected through bolts to achieve an adjustable relative angle connection. The telescopic support rod is an existing one). The support rod can be a telescopic rod body, which elongates during use to support the aerial device 2 at a high position and shortens when not in use for easy storage. The upper end surface of the support device 3 has the receiving bin 302 for supporting the aerial device 2. After the support device 3 supports the aerial device 2, by applying force to the support rod and the support device 3, and at the same time applying force to the lock component through the aerial device 2, the lock component is in the locking station or the unlocking station.

[0058] Specifically, the above-mentioned lock component includes at least two radially telescopic elastic sliders 100 arranged at the cover opening of the fixed seat 1. The free end of the elastic slider is engaged and limited with the limit groove 201. When the elastic slider extends, the free end of the elastic slider extends into the limit groove to relatively fix the aerial device 2 and the fixed seat 1; when the elastic slider retracts, the free end of the elastic slider disengages from the limit groove, and the aerial device 2 can relatively disengage from the fixed seat 1 due to gravity. The specific structure for realizing the telescoping of the elastic slider is as follows:

[0059] The elastic slider slides in the slideway 101 of the fixed seat 1. A compression spring 102 is provided between the fixed seat 1 and the elastic slider for driving the elastic slider to move deep into the limiting groove. The elastic slider is connected to the first end of a rigid pulling rope 103 (which can be a steel wire). The second end of the rigid pulling rope is connected to a lifting seat 104. The lifting seat has a first station for pulling the rigid pulling rope to retract the elastic slider and a second station for loosening the rigid pulling rope to extend the elastic slider. The first station of the lifting seat corresponds to the unlocking station of the locking assembly, that is, the elastic slider 100 of the locking assembly retracts, and the aerial device 2 can easily enter or detach from the mounting cavity of the fixed seat 1. The second station of the lifting seat corresponds to the locking station of the locking assembly, that is, the elastic slider 100 of the locking assembly extends, and the aerial device 2 can be locked in the fixed seat 1.

[0060] The bottom of the cover body of the fixed seat 1 is provided with a cover-shaped seat 105 and the lifting seat 104 which is arranged on the cover-shaped seat and can be lifted and lowered. The lifting seat is provided with a polygonal groove 106 (a pentagon is shown in the figure, but it is not limited to a pentagon, and it can also be other types of mechanical switches. The polygonal groove 106 is arranged on the inner wall surface of the strip groove 120 of the lifting seat), and the cover-shaped seat is provided with a limit rod 107. As shown in the figure, the limit rod 107 is a long strip plate (the upper end of the limit rod 107 is rotatably hinged to the cover-shaped seat 1 05), the limiting rod 107 extends from top to bottom into the strip groove 120, and the lower part of the limiting rod is provided with a convex column 108 that can be embedded in the polygonal groove, and an extrusion spring 109 is provided between the lifting seat and the cover-shaped seat (that is, the spring is in a compressed state), so that the lifting seat has a tendency to move from the first position to the second position. When the lifting seat is in the first position, the convex column is limited at the first limit point position of the polygonal groove, and when the lifting seat is in the second position, the convex column is limited at the second limit point position of the polygonal groove.

[0061] Through the above structure, when the lifting seat is pushed to the first position (such as Figure 8 , Figure 10 As shown in the figure, the protruding column 108 is limited at the first limit position of the polygonal groove. At this time, the lifting seat pulls the rigid pulling rope to retract the elastic slider, and the limit groove of the aerial device 2 is not limited by the free end of the elastic slider. Then, the aerial device 2 can be separated from the fixed seat 1 due to gravity, that is, the first position of the lifting seat corresponds to the unlocking position of the locking assembly; when the lifting seat is pushed to the second position due to the action of the extrusion spring (as shown in the figure), the protruding column 108 is limited at the first limit position of the polygonal groove. Figure 9 , Figure 11 As shown), the convex column is limited at the second limit point position of the polygonal groove. At this time, the lifting seat relaxes the rigid pulling rope to allow the elastic slider to extend under the action of the compression spring. The limiting groove of the aerial equipment 2 is limited by the free end of the elastic slider, and the aerial equipment 2 cannot be separated from the fixed seat 1, that is, the second position of the lifting seat corresponds to the locking position of the locking assembly.

[0062] For stable and reliable use, four axial limiting channels 110 are provided on the circumferential side of the above-mentioned cover-shaped seat. Four rod bodies 111 extending out of the limiting channels are provided on the lifting seat. Four elastically expandable and contractible elastic sliders are provided at the cover opening of the fixed seat 1. The first end of a rigid pulling rope is connected to each elastic slider respectively, and the second end of the rigid pulling rope is connected to the end of the rod body. A top column 112 that can be pushed by the upper part of the high-altitude device 2 is fixedly provided at the lower part of the lifting seat. After the high-altitude device 2 is forced in the axial direction of the support rod and the support device 3, that is, in the direction in which the high-altitude device 2 moves relatively away from or close to the fixed seat 1, the top column and the lifting seat are pushed. After being pushed once, the lifting seat is in the first working position, and after being pushed again, the lifting seat is in the second working position. The rigid pulling rope is limited and guided by a plurality of fixed pulleys.

[0063] A power supply incoming line port 114, a power supply step-down module 115 (the power supply step-down module 115 can reduce the original 220V voltage to a low voltage below 24V, which can not only increase the service life of the high-altitude device 2, but also ensure the safety of the disassembly and assembly of the high-altitude device 2) and a first contact terminal 116 are provided on the body 11 of the above-mentioned fixed seat. The first contact terminal 116 is a power supply point. The first contact terminal 116 is a circular conductive sheet, which includes an arc-shaped live wire conductive sheet 117, a neutral wire conductive sheet 118 and an insulator 119 located between the ends of the live wire conductive sheet and the neutral wire conductive sheet. The live wire conductive sheet and the neutral wire conductive sheet are respectively connected to the live wire and the neutral wire of the power supply. The circular conductive sheet can be a metal conductor such as a copper sheet or a silver sheet. Of course, it can also be a contact point structure of any shape. The insulator 119 can separate the live wire conductive sheet and the neutral wire conductive sheet, which can not only ensure that the positive and negative poles will not be short-circuited, but also ensure that the high-altitude device 2 can be installed at any angle in the circumferential direction.

[0064] The above-mentioned limiting groove is a circular groove provided on the high-altitude device 2. Two second contact terminals 202 that can be in electrical contact with the first contact terminal 116 are provided on the outer surface of the high-altitude device 2 above the circular groove. The two second contact terminals 202 are also separated by an insulator in the middle. The second contact terminal 202 is a spherical convex part. The second contact terminal 202 is electrically connected to the electrical components in the high-altitude device 2 to supply power to the electrical components after the first contact terminal 116 is in contact with the second contact terminal 202.

[0065] To improve the sealing performance, a sealing gasket 204 is provided on the opposite surfaces of the circular groove of the high-altitude device 2. A storage groove 205 for placing vulnerable parts 206 is provided on the upper surface of the high-altitude device 2. At the same time, a sealing gasket is provided at the notch of the storage groove 205, and an elastic sealing gasket 207 is provided above the second contact terminal 202, which can not only ensure the movement space during lifting, but also play an efficient waterproof role for the fixed seat 1.

[0066] As shown in the figure, the upper end of the top column 112 is fixedly connected to the lower end of the lifting seat, so that when the top column is pushed by the high-altitude device 2, the top column 112 can directly act on the lifting seat. In addition, for reasonable design, a third contact terminal 121 and a fourth contact terminal 122 are respectively provided on the lower end surface of the lifting seat and the upper end surface of the bottom plate of the hood-shaped seat.

[0067] As Figure 15 shown, a fault indicator light 203 located on the outer peripheral side of the high-altitude device 2 is provided on the series circuit between the second contact terminal 202 and the electrical component in the high-altitude device 2. The fault indicator light 203 is connected in parallel with the voltage comparator 208 across both ends of the vulnerable part 206 in the electrical component; when the vulnerable part 206 is damaged, the voltage comparator 208 connected in parallel with the vulnerable part 206 can convert the analog signal into a high level. At this time, the fault indicator light 203 lights up. The fault indicator light 203 is arranged on the outer peripheral side of the high-altitude device 2, which is convenient for observing whether the vulnerable part 206 is damaged.

[0068] As Figure 16 shown, a third contact terminal 121 and a fourth contact terminal 122 are respectively provided on the lower end surface of the lifting seat 104 and the upper end surface of the bottom plate 124 of the hood-shaped seat 105. The third contact terminal 121 is a metal conductor, mainly for electrical contact with the fourth contact terminal 122; the fourth contact terminal 122 is a strip-shaped block, and a conductive bolt 123 that connects the entire energized circuit is electrically connected to the fourth contact terminal 122; the bolt counterbore on the fourth contact terminal 122 and the four bolt holes on the bottom plate 124 of the hood-shaped seat 105 are connected by bolts; four supports 125 are provided on the upper surface of the bottom plate of the hood-shaped seat for supporting the limiting rod body 111.

[0069] The voltage comparator (a commercially available component, model LM393) is connected in parallel with the vulnerable part 206. That is, the voltage comparator LM393 can only operate when the device is powered on. When it does not operate, the fault indicator light does not light up, which can ensure no false alarm in the power-off state.

[0070] As Figure 14 shown, the energized operation mechanism of the voltage comparator LM393: when the 3rd pin Ui1+ of the voltage comparator LM393 is greater than the 2nd pin Ui1-, Uo1 = 1, that is, a high level, and the fault light is on; when the 3rd pin Ui1+ is less than the 2nd pin Ui1-, Uo = 0, that is, a low level, and the fault light is off; set Ui1+ to 50% of the input voltage 24V of the vulnerable part 206, which is 12V, and Ui1- is the measured voltage at the output end of the vulnerable part 206. When Ui1- is less than 12V, that is, when Ui+ > Ui-, Uo1 = 1, that is, a high level, and the fault light is on; conversely, when Ui1- is greater than 12V, the fault light is off.

[0071] When the utility model works,

[0072] When the aerial equipment 2 needs to be installed, first fix the support device 3 on the support rod 5, and then place the aerial equipment 2 in the accommodation cavity on the support device 3. As the support rod 5 continues to be pushed up, the aerial equipment 2 approaches the fixed seat 1. After the aerial equipment 2 is continuously pushed up, the periphery above the circular groove of the aerial equipment 2 pushes the elastic slider backward, and then the elastic slider 100 is inserted into the circular groove under the action of the compression spring 102. At this time, the aerial equipment 2 is under the action of the elastic slider and is in the locked position and cannot be separated. At this time, the lifting seat is in the second position, and the convex column on the limit rod is limited at the second limit point position of the polygonal channel.

[0073] When the aerial equipment 2 needs to be disassembled, first fix the support device 3 on the support rod 5, and the support rod 5 continues to be pushed up so that the aerial equipment 2 is placed in the accommodation cavity on the support device 3. Then the support rod 5 pushes the aerial equipment 2, so that the aerial equipment 2 acts on the top column and the lifting seat, and the convex column on the limit rod is limited at the first limit point position of the polygonal channel. At this time, the lifting seat pulls the rigid pulling rope to retract the elastic slider 100, and the limit groove of the aerial equipment 2 is not limited by the free end of the elastic slider, so the aerial equipment 2 can freely disengage from the fixed seat 1 due to gravity. In this state, the aerial equipment 2 can freely enter and exit the fixed seat.

[0074] The above Figure 1-11 is the first embodiment of the present application. Figure 12 This is the second embodiment of the present application. The difference between the second embodiment and the first embodiment is that the fixed seat 1 of the first embodiment is fixed at a high position with the cover opening facing down, and the aerial equipment 2 is installed from bottom to top; the fixed seat 1 of the second embodiment is fixed at a high position with the cover opening facing up, and the aerial equipment 2 is installed from top to bottom. A spring 6 is added to the aerial equipment 2 compared with the first embodiment, and this spring 6 overcomes the weight of the aerial equipment 2, which is beneficial to disassembly and assembly. Other structures and working principles are the same as those of the first embodiment.

[0075] Advantages of the present utility model:

[0076] 1. The installation and removal of the aerial equipment 2 are not limited to hand-contact installation. In particular, the installation of aerial equipment below 10 meters can be completed by using the telescopic support rod 4. The length of the support rod 5 is selected according to the installation height of the aerial equipment 2.

[0077] 2. The present application uses machinery to achieve disassembly and assembly, eliminating a large number of electronic components and not setting a storage battery, greatly increasing the reliability of the component; there is no need to consider the problem of inconvenient installation and removal caused by long-term power outages.

[0078] 3. It can achieve live installation and removal, and use a safe voltage below 24V after rectification. Therefore, there will be no arcing during installation and removal, improving safety.

[0079] 4. The replacement of the high-altitude device 2 no longer requires manual disconnection and connection of wires, nor does it require manual contact with the device for disconnection, connection and installation. Only by using the method of jacking up the support rod can the replacement of the high-altitude device 2 be quickly realized, saving a large amount of working time.

[0080] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them; although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that: it is still possible to modify the specific implementation manners of the present invention or make equivalent replacements for some technical features; without departing from the spirit of the technical solutions of the present invention, they should all be covered within the scope of the technical solutions claimed by the present invention.
