Description

Technical Field

[0001] The present invention relates to the technical field of installation and maintenance of electric equipment, and in particular to an auxiliary installation and maintenance device for electric equipment. Background Art

[0002] Power equipment refers to the various devices and equipment used in power systems for power generation, transmission, distribution, transformation, and maintenance. They are key components for the production, transmission, distribution, conversion, control, protection, and consumption of electrical energy. These devices range from production equipment that converts primary energy into electrical energy, to transmission lines and transformers for power transmission and distribution, and to secondary equipment that monitors, controls, regulates, and protects the power system. Power equipment plays a vital role in the power industry, ensuring the safe, stable, and efficient operation of the power system.

[0003] A search revealed that Chinese patent publication number CN111064123B discloses a pole-lifting auxiliary installation and maintenance device for electric power equipment. A symmetrically arranged arc-shaped frame structure can clamp a utility pole, while multiple climbing clamping structures are evenly arranged on the inner side of the arc-shaped frame in a circular pattern. Specifically, an elastic structure composed of an arc-shaped spring steel plate and attached legs is evenly arranged on the outer side of the climbing motor. The rotation of the climbing motor drives the outer elastic structure to climb, thereby driving the entire device upward or downward, providing a platform and assistance for the installation and maintenance of electrical equipment. However, this solution still has the following shortcomings in actual use:

[0004] Although the above-mentioned auxiliary installation and maintenance device for electric equipment can move up and down along the utility poles, it provides a convenient operating platform for the installation and maintenance of electric equipment, greatly improving work efficiency. However, since utility poles are usually set high to ensure the coverage and efficiency of power transmission, when the auxiliary device rises to the top of the utility pole for high-altitude operations, its stability and safety become a crucial issue. Once the staff makes any slight mistake during the operation, such as improper operation, misjudgment, or mechanical failure of the equipment itself, it may cause the entire device to lose balance and then move down or even fall. This emergency situation will not only cause potential damage to the electric equipment undergoing repair or installation, but more importantly, it will pose a serious threat to the life safety of the staff and may cause serious personal injury accidents.

[0018] Beneficial effects of the present invention:

[0019] 1. This auxiliary installation and maintenance device for electric power equipment is equipped with a connecting plate and an emergency stop assembly. When the device accidentally falls on a utility pole, the auxiliary wheel cannot rotate due to the locking effect of the one-way bearing. The friction with the utility pole causes the supporting plate to rotate and compress the compressed airbag. The gas in the compressed airbag enters the lifting airbag, causing the cover plate to move to the outer wall of the drive wheel. The drive wheel is fixed by the brake pad and the emergency stop block, thereby quickly stopping the falling of the entire device and effectively protecting workers from injury. This emergency stop mechanism provides important safety protection for high-altitude operations.

[0020] 2. This auxiliary installation and maintenance device for power equipment has a trigger assembly. The emergency stop trigger mechanism relies on the friction between the auxiliary wheel and the utility pole and the locked state of the one-way bearing when the device falls. This trigger mechanism is sensitive and reliable, and can respond quickly when an accident occurs in the device. It can achieve an emergency stop through a series of chain reactions, avoiding safety hazards caused by operational errors or other factors.

[0021] 3. This auxiliary installation and maintenance device for electric power equipment has a compact drive assembly and stable transmission, which can ensure that the device moves smoothly on the utility pole. At the same time, by adjusting the adjustment plate, adjustment screw, guide rod and other components, the position of the drive wheel can be precisely adjusted to adapt to utility poles of different diameters, thereby improving the applicability and stability of the device.

[0022] 4. This type of auxiliary installation and maintenance device for electric power equipment is equipped with an operating component, and the operating table on the device can be rotated through the meshing action of the drive motor, drive gear and fixed teeth. This rotation mechanism allows the operating table to flexibly adjust its position according to work needs, making it convenient for workers to install and repair electric power equipment. At the same time, through the cooperation of components such as the slide, slider, annular groove and guide groove, the stability and stability of the operating table during the rotation process are ensured, thereby improving work efficiency and safety.

[0037] like Figures 1 to 9As shown, an auxiliary installation and maintenance device for electric power equipment includes two supporting half-hoops 1 and a sealing arc plate 2 hinged to the open ends of the supporting half-hoops 1, a connecting plate 3 is symmetrically fixedly installed between the two supporting half-hoops 1, two driving wheels 4 are provided on the connecting plate 3, and two sets of emergency stop components corresponding to the driving wheels 4 are provided on the side surfaces of the two connecting plates 3, driving components are provided on the two supporting half-hoops 1, and two sets of trigger components corresponding to the emergency stop components are symmetrically provided on the lower supporting half-hoop 1, two spring telescopic rods 9 are symmetrically fixedly installed on the inner walls of the two supporting half-hoops 1 and the sealing arc plate 2, and a stabilizing wheel 10 is rotatably installed on the telescopic end of the spring telescopic rod 9;

[0038] The emergency stop assembly includes an adjustment plate 51 arranged on the side of the connecting plate 3, the driving wheel 4 is rotatably mounted on the side of the adjustment plate 51 through a support frame, a transmission shaft 52 is fixedly mounted on the side of the driving wheel 4, and the end of the transmission shaft 52 passes through the support frame, and a number of evenly distributed telescopic guide rods 53 corresponding to the two driving wheels 4 are fixedly mounted on the side of the adjustment plate 51, and the telescopic ends of the several telescopic guide rods 53 on the same side are fixedly mounted with a cover plate 54. A number of blocks 55 distributed in a ring array are fixedly mounted on both sides of the driving wheel 4, and emergency stop blocks 56 are fixedly mounted on both ends of the inner wall of the cover plate 54. A lifting airbag 57 is provided between the cover plate 54 and the adjusting plate 51, and a brake pad 58 adapted to the driving wheel 4 is provided on the inner wall of the cover plate 54. An adjusting screw 59 is rotatably mounted on the side of the adjusting plate 51, and a guide rod is fixedly mounted on the side of the adjusting plate 51. The ends of the adjusting screw 59 and the guide rod both pass through the side of the connecting plate 3;

[0039] When in use, the sealing arc plates 2 on the two supporting half hoop rings 1 can be opened first, and then the entire device can be set on the telephone pole, and then the sealing arc plates 2 can be closed and fixed by the bayonet pin, and the entire device can be installed on the telephone pole. After the device is installed, the stabilizing wheel 10 at the telescopic end of the spring telescopic rod 9 can fit with the outer wall of the telephone pole, and the stabilizing wheel 10 can position the supporting half hoop ring 1 under the support of the spring telescopic rod 9, and then the adjusting screw 59 can be rotated. Since the adjusting plate 51 is connected to the connecting plate 3 through the adjusting screw 59 and the guide rod, the adjusting screw 59 can drive the adjusting plate 51 to move when it rotates, so as to The driving wheel 4 on the adjustment plate 51 can be adjusted to fit the outer wall of the utility pole. When the device as a whole moves upward and falls accidentally, the airbag 57 is lifted up under the action of the trigger component to expand and drive the cover plate 54 to extend the telescopic guide rod 53. When the cover plate 54 moves, it can reach the outer wall of the driving wheel 4, and the brake pads 58 on the inner wall of the cover plate 54 slow down the driving wheel 4. At the same time, the emergency stop blocks 56 at both ends of the inner wall of the cover plate 54 can engage with the blocking blocks 55 on the side of the driving wheel 4, thereby fixing the driving wheel 4 and preventing the driving wheel 4 from rotating, thereby achieving an emergency stop of the entire device and preventing workers from falling and getting injured.

[0040] like Figure 2 、 Figure 5 、 Figure 6 As shown, the trigger assembly includes a bracket 61 fixedly mounted on the outer wall of the supporting half hoop 1, a rotating plate 62 is rotatably mounted on the inner wall of the bracket 61, and the bottom end of the rotating plate 62 is hingedly connected to a butt plate 63, an outer wall of the connecting plate 3 is hingedly connected to an electric push rod 64, and the telescopic end of the electric push rod 64 is hinged to the top of the rotating plate 62, and a pressure plate 65 is fixedly mounted on the side opposite to the rotating plate 62 and the butt plate 63, a compression air bag 66 is provided between the two pressure plates 65, a guide tube 67 is provided on the compression air bag 66, and the upper end of the guide tube 67 is connected to the lifting air bag 57, a mounting bracket 68 is rotatably mounted on the bottom end of the butt plate 63, and a shaft 69 is fixedly mounted on the inner wall of the mounting bracket 68, and the outer wall of the shaft 69 is provided with a one-way bearing 610, and the outer wall of the one-way bearing 610 is provided with an auxiliary wheel 611, and the locking directions of the two one-way bearings 610 are opposite;

[0041] The staff can extend the electric push rod 64. When the electric push rod 64 is extended, it can drive the rotating plate 62 to rotate through the bracket 61, thereby driving the abutment plate 63 and the auxiliary wheel 611 to rotate, so that the auxiliary wheel 611 can fit the outer wall of the utility pole. At this time, the driving component can be turned on to drive the entire device, so that the entire device moves upward along the utility pole. If the device accidentally falls downward due to operational reasons or other factors during the ascent of the device, since the outer wall of the auxiliary wheel 611 fits the outer wall of the utility pole, the locking directions of the two one-way bearings 610 are opposite, and the auxiliary wheel 611 can rotate as the device moves upward. When the device falls and moves downward, the auxiliary wheel 611 can rotate in the opposite direction, and the one-way bearing 610 is in a locked state, so the auxiliary wheel 611 cannot The push plate 63 rotates under the action of the friction force with the electric pole and drives the pressure plate 65 to rotate to compress the compressed air bag 66. At this time, the gas in the compressed air bag 66 can enter the lifting air bag 57 through the conduit 67. In the process of the device moving downward, due to the problem of the one-way bearing 610 being locked, the staff needs to shorten the electric push rod 64 before moving downward to separate the auxiliary wheel 611 from the electric pole, otherwise it cannot move downward. If a fall occurs during the downward movement, the staff can quickly start the electric push rod 64 to extend it to its longest state, which can drive the push plate 63 to rotate and the auxiliary wheel 611 can be pressed against the electric pole. Under the action of pressure, the push plate 63 can rotate and compress the compressed air bag 66, thereby realizing the emergency stop function.

[0042] like Figure 2 、 Figure 7As shown, the drive assembly includes a fixing frame 71 fixedly mounted on the inner wall of the two supporting half hoop rings 1, two connecting rods 72 are penetrated on both sides of the fixing frame 71, and the ends of the connecting rods 72 close to the transmission shaft 52 are provided with universal joints 73, a telescopic transmission rod 74 is fixedly mounted between the two universal joints 73, and a driven bevel gear 75 is fixedly mounted on the end of the connecting rod 72 away from the universal joint 73. A driving shaft 76 is rotatably mounted on the inner side of the fixing frame 71, and two driving bevel gears 78 meshing with the driven bevel gear 75 are set on the driving shaft 76. A servo motor 77 is fixedly mounted on the top surface of the supporting half hoop ring 1, and the output end of the servo motor 77 is connected to the top end of the driving shaft 76 through a driven wheel and a synchronous belt transmission.

[0043] When the drive assembly is turned on, the servo motor 77 can drive the drive shaft 76 to rotate through the driven wheel and the synchronous belt. When the drive shaft 76 rotates, the two driving bevel gears 78 on it can rotate, and the driving bevel gear 78 engages with the driven bevel gear 75, thereby driving the driven bevel gear 75 and the connecting rod 72 to rotate. When the two adjustment plates 51 are adjusted in position, since the two adjacent universal joints 73 are connected by the telescopic transmission rod 74, the connection between the two universal joints 73 can be ensured by the telescopic transmission rod 74, and stable transmission can be performed. When the connecting rod 72 rotates, the transmission shaft 52 can be driven by the universal joint 73 and the telescopic transmission rod 74, thereby driving the drive wheel 4 to rotate, so that the drive wheel 4 is driven to rotate along the outer wall of the pole, so as to drive the entire device. Through the connection between the driving bevel gear 78 and the driven bevel gear 75, the drive wheels 4 on both sides can rotate in different directions, ensuring that the device can move stably as a whole.

[0044] like Figure 1 、 Figure 2 、 Figure 8 、 Figure 9 As shown, an operating assembly is provided on the connecting plate 3 and an upper supporting half hoop ring 1, and the operating assembly includes a mounting ring plate 81 fixedly mounted on the outer wall of the two connecting plates 3, a sealing ring plate 82 is hingedly connected to the open end of the mounting ring plate 81, an annular groove 83 is provided on the top surface of the mounting ring plate 81 and the sealing ring plate 82, a guide groove 84 is provided on the outer wall of the supporting half hoop ring 1, a slide plate 85 is slidably mounted on the inner wall of the guide groove 84, a slider 86 is slidably mounted on the inner wall of the annular groove 83, and a connecting frame 87 is fixedly mounted on the top surface of the slider 86. Two reinforcing rods 88 are symmetrically fixedly installed between the slide 85 and the connecting frame 87. An operating platform 89 is fixedly installed at the bottom end of the connecting frame 87. A protective door 810 is provided at the entrance and exit of the operating platform 89. A drive motor 811 is fixedly installed on the top surface of the connecting frame 87. A drive gear 812 is fixedly installed at the output end of the drive motor 811. A plurality of fixed teeth 813 distributed in an annular array are fixedly installed on the outer walls of the supporting half hoop 1 and the sealing arc plate 2, and the fixed teeth 813 are meshed with the drive gear 812.

[0045] When the device is installed, the sealing ring plate 82 at the end of the mounting ring plate 81 needs to be opened so that the device can be mounted on the electric pole and installed along with the supporting half hoop 1. When the device rises to the working position, the staff can control the drive motor 811 according to the working conditions. When the drive motor 811 is turned on, it can drive the drive gear 812 to rotate, and the drive gear 812 engages with the fixed teeth 813. Then, under the action of the two, the operating platform 89, the connecting frame 87, the reinforcing rod 88, etc. can slide along the annular groove 83 and the guide groove 84 through the slide plate 85 and the slider 86 to realize the rotation of the operating platform 89, so as to change the position of the operating platform 89 to facilitate the installation and maintenance of the power equipment, which is more convenient to use.

[0046] The technical solution provided by the present invention is that when in use, the sealing arc plates 2 on the two supporting half hoop rings 1 can first be opened, and then the entire device can be sleeved on the telephone pole, and then the sealing arc plates 2 can be closed and fixed by means of a bayonet, and the entire device can be installed on the telephone pole. After the device is installed, the stabilizing wheel 10 at the telescopic end of the spring telescopic rod 9 can fit with the outer wall of the telephone pole, and the stabilizing wheel 10 can position the supporting half hoop ring 1 under the support of the spring telescopic rod 9, and then the adjusting screw 59 can be rotated. Since the adjusting plate 51 is adjusted by the adjusting screw 59 and the guide rod and The connecting plate 3 is connected, so when the adjusting screw 59 rotates, the adjusting plate 51 can be driven to move, so that the driving wheel 4 on the adjusting plate 51 can be adjusted to fit the outer wall of the utility pole. After the adjustment is completed, the staff can extend the electric push rod 64. When the electric push rod 64 is extended, it can drive the rotating plate 62 to rotate through the bracket 61, thereby driving the abutment plate 63 and the auxiliary wheel 611 to rotate, so that the auxiliary wheel 611 can fit the outer wall of the utility pole. At this time, the driving assembly can be turned on to drive the entire device, so that the entire device can move upward along the utility pole;

[0047] When the drive assembly is turned on, the servo motor 77 can drive the drive shaft 76 to rotate through the driven wheel and the synchronous belt. When the drive shaft 76 rotates, the two driving bevel gears 78 on it can rotate, and the driving bevel gear 78 meshes with the driven bevel gear 75, thereby driving the driven bevel gear 75 and the connecting rod 72 to rotate. When the two adjustment plates 51 are adjusted in position, since the two adjacent universal joints 73 are connected by the telescopic transmission rod 74, the connection between the two universal joints 73 can be ensured by the telescopic transmission rod 74, so that stable transmission can be performed. When the connecting rod 72 rotates, the transmission shaft 52 can be driven by the universal joint 73 and the telescopic transmission rod 74, thereby driving the driving wheel 4 to rotate, so that the driving wheel 4 is driven to rotate along the outer wall of the utility pole, so as to drive the entire device. Through the connection between the driving bevel gear 78 and the driven bevel gear 75, the driving wheels 4 on both sides can rotate in different directions, ensuring that the device can move stably as a whole.

[0048] If the device falls down unexpectedly due to operational reasons or other factors during the ascent process, the outer wall of the auxiliary wheel 611 is in contact with the outer wall of the utility pole, and the locking directions of the two one-way bearings 610 are opposite, so the auxiliary wheel 611 can rotate as the device moves up. When the device falls and moves downward, the auxiliary wheel 611 can rotate in the opposite direction, while the one-way bearings 610 are in a locked state. Therefore, the auxiliary wheel 611 cannot rotate. Under the action of the friction force with the utility pole, the support plate 63 can rotate and drive the pressure plate 65 to rotate to compress the compressed air bag 66. The air in the compressed airbag 66 can enter the lifting airbag 57 through the conduit 67, and the lifting airbag 57 can expand and drive the cover plate 54 to extend the telescopic guide rod 53. When the cover plate 54 moves, it can reach the outer wall of the driving wheel 4, and the brake pads 58 on the inner wall of the cover plate 54 slow down the driving wheel 4. At the same time, the emergency stop blocks 56 at both ends of the inner wall of the cover plate 54 can be engaged with the clamping blocks 55 on the side of the driving wheel 4, thereby fixing the driving wheel 4 and preventing the driving wheel 4 from rotating, thereby achieving an emergency stop of the entire device and preventing workers from falling and getting injured.

[0049] When the device moves downward, if the one-way bearing 610 is locked, the staff needs to shorten the electric push rod 64 before moving downward to separate the auxiliary wheel 611 from the pole, otherwise it cannot move downward. If it falls during the downward movement, the staff can quickly start the electric push rod 64 to extend it to its longest state, which can drive the support plate 63 to rotate and the auxiliary wheel 611 to be pressed against the pole. Under the action of pressure, the support plate 63 can rotate and compress the compression airbag 66, thus realizing the emergency stop function.

[0050] When the device is installed, the sealing ring plate 82 at the end of the mounting ring plate 81 needs to be opened so that the device can be mounted on the electric pole and installed along with the supporting half hoop 1. When the device rises to the working position, the staff can control the drive motor 811 according to the working conditions. When the drive motor 811 is turned on, it can drive the drive gear 812 to rotate, and the drive gear 812 engages with the fixed teeth 813. Then, under the action of the two, the operating platform 89, the connecting frame 87, the reinforcing rod 88, etc. can slide along the annular groove 83 and the guide groove 84 through the slide plate 85 and the slider 86 to realize the rotation of the operating platform 89, so as to change the position of the operating platform 89 to facilitate the installation and maintenance of the power equipment, which is more convenient to use.

Within the scope of the present invention, the technical features in the above embodiments or different embodiments may be combined, the steps may be implemented in any order, and there are many other variations of the different aspects of the present invention as described above, which are not provided in detail for the sake of simplicity.
