Description

Technical Field

[0001] The utility model relates to the field of turnover devices, in particular to a turnover assembly device for an insulating basin. Background Art

[0002] GIS equipment is an important part of the substation system. The quality of the isolating switch components directly affects the reliability of the power grid system. The insulating basin is an important part in the high-voltage switch and is used to distinguish insulation and separate gas chambers. Its assembly quality directly affects the safe operation and reliability of the isolating switch. Most of the existing assembly methods use manual lifting and docking, but the insulating basin needs to be flipped during the installation process. For example, electrical connectors need to be installed on both sides of the insulating basin. During assembly, the electrical connectors on one side of the insulating basin are installed first, and then the insulating basin is flipped 180° to install the electrical connectors on the other side. However, if the lifting method is used for flipping, problems such as shaking may occur during the flipping process, which will pose a safety hazard to both operators and equipment.

[0003] The Chinese patent with authorization announcement number: CN216067360U discloses an insulating basin flipping tool and an insulating basin flipping auxiliary clamp. The insulating basin flipping tool includes a frame and two auxiliary clamps. The frame includes two vertical frames arranged at intervals. The auxiliary clamp includes a pallet. The pallet includes a supporting plate section and a rotating shaft connecting plate section. The supporting plate section and the rotating shaft connecting plate section are perpendicular to each other. A rotating shaft is provided on the outer side of the rotating shaft connecting plate section, and a pallet fixing hole is provided on the supporting plate section; a pressing plate is located on the inner side of the rotating shaft connecting plate section, including a clamping plate section, the clamping plate section is arranged parallel to the supporting plate section, and a pressing plate fixing hole is provided on the clamping plate section; a locking bolt is passed through the pressing plate fixing hole and the pallet fixing hole. When the edge of the insulating basin is placed between the supporting plate section and the clamping plate section, the supporting plate section and the clamping plate section clamp the edge of the insulating basin. The two auxiliary clamps are respectively assembled on the two vertical frames through their respective rotating shafts. The device can be used to turn over the insulating basin, and the turning process is relatively stable. Turning over by the device will not cause shaking and other problems as in the process of hoisting and turning over.

[0004] However, when the insulating basin is turned over by the device for installation, the insulating basin can only be kept at one height: the height of the stand. However, the insulating basin needs to be installed at different heights of the GIS. When the insulating basin is installed into the GIS by the above-mentioned turning device, either the height of the turning device is adjusted or the position and height of the GIS is adjusted. Both methods are relatively difficult, making the installation process of the insulating basin extremely difficult. Utility Model Content

[0022] The basic concept of this utility model:

[0023] An insulating basin flip assembly device includes a base, on which a flip device for flipping the insulating basin is arranged, and the flip device can flip 180 degrees. A lifting device for driving the flip device to move up and down is arranged on the base, and the flip device is installed at the output end of the lifting device so as to be lifted and lowered with the lifting device.

[0024] When in use, first install the insulating basin on the flip device, then adjust the height of the insulating basin to a suitable position through the lifting device, then flip the insulating basin through the flip device, and install other structures. After the installation is completed, flip the insulating basin to an angle that is convenient for installation on the GIS, then raise the insulating basin to a suitable height through the lifting device, and then install the insulating basin on the GIS.

[0025] The utility model improves the prior art. Specifically, a lifting device is added to the existing flipping device, so that the flipping device can move up and down with the lifting device to adjust the height of the flipping device, so that the insulating basin can meet different installation positions of the insulating basin on the GIS during installation, thereby solving the problem that the insulating basin flipping device in the prior art has poor adaptability to different height positions, resulting in difficulty in installing the insulating basin.

[0026] The features and performance of the present invention are further described in detail below in conjunction with the embodiments.

[0027] Embodiment 1 of the insulating basin flip assembly device of the utility model:

[0028] like Figure 1-4 As shown: an insulating basin flip assembly device, including a base 1, a flip device 2 is arranged on the base 1, a lifting device is arranged on the base 1, and the flip device 2 is installed at the output end of the lifting device so as to be lifted and lowered along with the lifting device.

[0029] The improvement of the utility model is not on the flipping device 2, so the specific structure of the flipping device 2 is not described in this embodiment. The flipping device 2 can adopt the flipping device 2 in the prior art: for example, the flipping device in the Chinese patent with authorization announcement number CN216067360U or the flipping device in the Chinese patent with authorization announcement number CN218110570U.

[0030] The base 1 in the utility model is provided with universal wheels, and the transportation of the device and the insulating basin is made more convenient by providing the universal wheels.

[0031] A lifting device is provided on the base 1, and the height of the flip device 2 is controlled by the lifting device. There is no specific restriction on the position of the lifting device on the base 1. For example, the lifting device is provided in the middle position of the base 1 or the lifting device is provided on one side of the base 1, and the flip device 2 extends out of the base 1. However, since some insulating basins are heavy, if the lifting device is provided at the above position, the center of gravity of the device may be excessively shifted, causing the device to overturn. Therefore, it is preferred that the lifting device is provided on one side of the base 1 and the flip device 2 is installed in the direction of the lifting device toward the other side of the base 1, so that the center of gravity of the device is relatively closer to the center position, less likely to overturn, and more stable during installation.

[0032] The lifting mechanism generally directly lifts the corresponding lifting part, but since the device needs to lift the relatively heavy insulator, it is relatively laborious to directly lift the flip device 2 through the lifting device. If some devices that can increase the torque are set, for example, the power mechanism is connected to the worm gear reduction mechanism, the power mechanism first drives the worm to rotate, thereby driving the turbine to rotate, and then lifts the flip device 2. Although it saves effort, it also increases the structure, and it is also necessary to adjust the output direction of the power mechanism during installation, which is relatively complicated overall. Therefore, in order to save effort and simplify the installation process, preferably: a guide frame 3 and a sliding plate 4 for installing the flip device 2 that is slidably installed on the guide frame 3 are provided on the base 1, and the lifting device also includes: a flexible traction member and a power mechanism, one end of the flexible traction member is fixed relative to the base 1 (in this embodiment, a fixed plate is provided on the guide frame 3, and the flexible traction member is fixed on the fixed plate. Of course, in other embodiments, it can also be directly fixed on the base 1, as long as it can be ensured to be relatively fixed with the base 1), and the other end is fixed on the sliding plate 4, and the lifting device also includes a movable pulley, and the power mechanism drives the movable pulley to tighten or loosen the flexible traction member, thereby realizing the lifting or lowering of the sliding plate 4. The purpose of saving effort is achieved by the movable pulley. Relatively speaking, its structure is simple, and there is no need to adjust the output direction of the power mechanism. Relatively speaking, it is easier to install.

[0033] Generally speaking, the movable pulley can be directly set, for example, a rod is directly extended from both sides of the movable pulley, a connecting structure is fixed on the rod, the connecting structure is connected to the telescopic cylinder at the top, and the telescopic cylinder is retracted to drive the movable pulley to rise, thereby driving the flip device 2 to rise. However, if this method is used, relatively speaking, during the lifting process of the device, the movable pulley may be offset during the movement, causing the flexible traction member to shake or even entangle. Therefore, preferably: an additional guide frame can be set on the base, and the guide frame can prevent the movable pulley from shifting or rotating when changing its position. However, setting an additional structure will make the structure complicated, so preferably: a guide groove is set on the guide frame 3, and a guide sliding fit is formed between the guide frame 3 and the movable pulley. In order to prevent the movable pulley from rotating and affecting the lifting, a guide groove is set on the guide frame 3 of the lifting device, and a guide member that cooperates with the guide groove is set on the movable pulley. Through the cooperation of the guide member and the guide groove, the movable pulley can slide back and forth on the guide frame 3, thereby preventing the movable pulley from shaking and shifting.

[0034] As long as a movable pulley is provided, the effect of labor saving can be achieved, so only one pulley block consisting of a movable pulley and a flexible traction member is required. However, when a pulley block consisting of only one movable pulley is provided, when facing a heavier insulating basin, the flexible traction member may break, resulting in failure of lifting and lowering, and the flip device 2 may fall, resulting in damage to the insulating basin or the flip device 2. Therefore, preferably: a plurality of pulley blocks consisting of a flexible traction member and a movable pulley are provided, for example: two, three or more are provided, and the plurality of movable pulleys are extended along the width direction of the flip device 2. However, it is not advisable to provide too many pulley blocks, as too many pulley blocks will result in a more complicated structure and higher cost. Therefore, preferably: two movable pulleys and flexible traction members are provided to form two pulley blocks.

[0035] However, when the flip device 2 is pulled by a pulley group composed of two movable pulleys and a flexible traction member, the two flexible traction members can be tightened or loosened by two power mechanisms, or pulled by one power mechanism. However, if tightened or loosened by two power mechanisms, the lifting process is easy to be out of sync, and the flip device 2 is easy to tilt; if tightened or loosened directly by one power mechanism, at least one flexible traction member will be offset and easily disengaged from the movable pulley. Therefore, preferably: the power output end of the power mechanism is connected to a laterally extending connecting shaft 7, and movable pulleys are installed on both sides of the connecting shaft 7. The laterally extending connecting shaft 7 allows multiple movable pulleys to be pulled by one power mechanism, which simplifies the structure relatively; and the flexible connecting members are in a parallel state on both sides of the movable pulley, making the traction process more stable and making it more difficult for the flexible traction member to be disengaged from the fixed pulley. And the movable pulley is guided and slid relative to the guide stand 3 through the connecting shaft 7 and the guide groove on the guide stand 3.

[0036] There are also various types of movable pulleys and flexible traction members, for example, they can be ordinary movable pulleys and traction ropes, or synchronous pulleys and synchronous belts, etc. However, in the above methods, it is easy for the movable pulley and the flexible traction member to be disengaged. Therefore, preferably, the movable pulley uses a sprocket 6, and the flexible traction member uses a chain 5. The sprocket 6 cooperates with the chain 5 to pull the flipping device 2, thereby realizing the lifting and lowering of the flipping device 2. Compared with other structures, the sprocket 6 and the chain 5 have better stability and better load-bearing effect, and can withstand greater force.

[0037] When the flip device 2 is raised or lowered, it is OK if the flexible traction member is directly exposed to the outside. However, when the flip device 2 is lifted, if the flexible traction member is disturbed, the flexible traction member may fail. Therefore, in order to prevent the flexible traction member from failing due to external interference, preferably: a protective cover 10 for protecting the flexible traction member is provided on the guide frame 3. The flexible traction member is shielded by providing a protective plate to prevent the flexible traction member from being disturbed by the outside world, thereby causing the lifting to fail. However, since the protective cover 10 will interfere with the flip device 2 and cause the flip device 2 to fail to rise or fall normally, the protective cover 10 only covers the upper end of the guide frame 3, which can play a protective role without causing the movable distance of the flip device 2 to become too small.

[0038] The position of the power mechanism is also variable. For example, a lifting motor can be set at the top of the guide frame 3, and the movable pulley can be lifted by the motor to drive the sliding plate 4 to rise. However, if the height of the power mechanism is too high, the center of gravity of the entire device will be too high, resulting in a decrease in the stability of the entire device. Therefore, preferably, the power mechanism is set at the bottom of one side of the guide frame 3 and is adjacent to the guide frame 3. The power mechanism is set at the bottom of one side of the guide frame 3, so that the center of gravity of the entire device moves downward relatively, thereby improving the stability of the entire device, and the power mechanism is adjacent to the guide frame 3, so that the volume of the entire device is relatively reduced.

[0039] There are also many types of power mechanisms: for example, the motor mentioned above, or the telescopic cylinder, but its structure is relatively complex, and the motor needs to be connected to electricity, and the telescopic cylinder needs to be equipped with a pump station. Therefore, preferably: a jack-type hydraulic cylinder 8 is used, and the power output end of the hydraulic cylinder 8 tightens or relaxes the flexible traction member to achieve the lifting and lowering of the flip device 2. The lifting and lowering of the flip device 2 is achieved by the hydraulic cylinder 8. Compared with other structures (such as motors), its structure is simple and the cost is relatively low. The hydraulic cylinder 8 has a self-locking function, and the flip device 2 can be kept at the corresponding height without the need for an additional locking structure. And the hydraulic cylinder 8 only needs manpower to drive, and has lower requirements on the environment. The hydraulic cylinder 8 is also connected to a driving handle 9 extending upward. When in use, the driving handle 9 is directly used to drive the hydraulic cylinder 8 to drive the chain 5 to move, thereby driving the flip device 2 to rise or fall.

[0040] When in use, first install the insulator on the flip device 2 with the top facing upward, flip the insulator 180° through the flip device 2 so that the bottom of the insulator faces upward, install the corresponding structure on the insulator, and then flip the insulator to 90° so that the insulator is perpendicular to the ground and the top of the insulator faces outward. Then, the driving handle 9 is swung by human power, so that the hydraulic cylinder 8 rises, driving the connecting shaft 7 to rise, thereby driving the sprocket 5 to move upward, thereby driving the sliding plate 4 and the flip device 2 to rise. After rising to a suitable position, the insulator is sent into the installation space through the universal wheel on the base. After installation, open the pressure relief valve on the hydraulic cylinder 8 to lower the flip device 2.

All equivalent structural changes made using the description and drawings of the present invention shall be included in the protection scope of the present invention.
