Description

Technical Field

[0001] The invention relates to the field of switch equipment assembly, and in particular to a cylinder hoisting device. Background Art

[0002] Gas Insulated Metal Enclosed switchgear (GIS) is widely used in substations. Its operation stability directly affects the stability of power transmission lines and substations. Quality problems will cause significant economic losses. Current transformers are key components of GIS equipment, and their assembly reliability and safety are crucial.

[0003] For example, the Chinese utility model patent with authorization announcement number CN205646613U discloses a gas-insulated metal-enclosed switchgear and a GIS power station using the same, wherein the GIS power station includes a circuit breaker and a current transformer, the circuit breaker is arranged at the bottom, and the current transformer is arranged above the circuit breaker, that is, the current transformer is arranged at a certain height from the ground, so naturally, when installing the current transformer, a lifting device is required to lift the current transformer, thereby moving the current transformer to the corresponding position.

[0004] like Figure 1 As shown, in the prior art, the current transformer includes a cylinder 11, and a cylinder flange 12 for connecting with other components in the GIS is provided at the end of the cylinder. The cylinder flange 12 is provided with a front side of the cylinder flange for docking with other components and a back side of the cylinder flange facing away from the flange surface. When the current transformer needs to be hoisted, a rope is often used to hoist the cylinder 11 of the current transformer, and the rope is used to tie the back side of the cylinder flange for hoisting. The cylinder flange 12 on the cylinder of some current transformers has a narrow flange, and the current transformer is heavy, so there is a risk of the hoisting rope slipping, which poses a safety hazard. Summary of the invention

[0005] The object of the present invention is to provide a cylinder hoisting device, which is used to solve the problem in the prior art that the cylinder flange is hoisted using a hoisting rope and the flange flange is narrow, which causes the hoisting rope to fall off easily.

[0006] In order to achieve the above purpose, the cylinder hoisting device in the present invention adopts the following technical scheme:

[0007] A cylinder lifting device comprises a mounting seat and at least two lifting parts hingedly arranged on the mounting seat, the lifting parts are provided with a hook structure for cooperating with a stopper on the back side of a cylinder flange, a hinged portion for hingedly cooperating with the mounting seat and a rope connecting structure for connecting with a lifting rope, the rope connecting structure and the hook structure are respectively located on both sides of the hinged portion; the hook structure has a lifting position for cooperating with the back side of the cylinder flange for lifting when rotating inwardly along the rotation stroke of the lifting part, and an avoidance position for allowing the cylinder flange to pass through when rotating outwardly; the cylinder lifting device also includes a retaining structure for keeping the lifting part at the lifting position.

[0008] The beneficial effects of the above technical scheme are: the present invention pioneers a cylinder lifting device, which facilitates the lifting of the cylinder to be lifted by arranging a mounting seat and a lifting member, and because the lifting member can rotate relative to the mounting seat to form two workstations, it is convenient to connect before lifting and carry during lifting; the hook structure is convenient to cooperate with the flange for stopping, and the rope connection structure is convenient to connect with the rope, and the hinged part and the setting position of the three make the hook structure and the rope connection structure rotatable relative to the hinged part, that is, forming a lever structure, and the holding structure is arranged so that the lifting member is in the lifting position during the lifting process, that is, at this time, the hook structure is always in cooperation with the back of the cylinder flange for stopping, and the hook structure is not easy to fall off, thereby solving the problem in the prior art that the cylinder flange is lifted by using a rope, and the rope is easy to fall off due to the narrow flange flange.

[0009] Furthermore, each lifting part is provided with at least one lifting hole, which constitutes the lifting rope connection structure. When the hook structure is in the lifting position, each lifting hole includes at least one inner lifting hole located on the inner side of the hinge part, and the inner lifting hole is used to cooperate with a lifting rope of a set length so that the hook structure has a torque to rotate toward the cylinder.

[0010] The beneficial effect of the above technical solution is that: by setting the position of the lifting hole, self-locking can be achieved, that is, during the lifting process, the hook structure will get closer and closer under the action of the gravity of the cylinder, and the rotation of the hook structure toward the cylinder will simultaneously generate a gripping torque, making it less likely to fall out.

[0011] Furthermore, the hanging member includes a hanging plate, the hanging holes are arranged on the hanging plate, and each hanging member has at least two hanging holes.

[0012] The beneficial effects of the above technical solution are: the structure of the hanging plate is simple, and it is convenient to set perforations on the hanging plate to form hanging holes; the two hanging holes can serve as backup for each other.

[0013] Furthermore, the hanging plate comprises a wide side section and a narrow side section, the hanging hole is located on the wide side section, and the hinged portion is located on the narrow side section.

[0014] The beneficial effect of the above technical solution is that the wide side section is easy to punch to form a lifting hole, and the narrow side section is easy to avoid the mounting seat, thereby facilitating rotation.

[0015] Furthermore, at least two first pin holes are provided on the lifting plate, and second pin holes corresponding to the first pin holes are provided on the mounting seat, wherein one of the first pin holes and the corresponding second pin holes constitute a hinge hole for installing the hinge shaft, and the remaining first pin holes and the corresponding second pin holes constitute stop holes for installing the stop pins, so that the lifting parts can be kept at the lifting position.

[0016] The beneficial effects of the above technical solution are: simple structure, easy to set up, and the lifting component can be switched between the hook structure and the avoidance station by passing the pin shaft through the anti-rotation hole.

[0017] Furthermore, the at least two first pin holes or the second pin holes are arranged vertically when the hook structure is in the lifting position.

[0018] The beneficial effects of the above technical solution are: it is convenient to set the pin holes on the mounting seat and the hanging parts, and it is convenient to align them after processing.

[0019] Furthermore, the hook structure has a lifting plane for cooperating with a stopper on the back side of the cylinder flange.

[0020] The beneficial effect of the above technical solution is that the lifting plane is convenient for increasing the contact area with the flange on the cylinder body, avoiding local stress.

[0021] Furthermore, the mounting seat has a limiting surface for cooperating with the front stopper of the cylinder flange, and buffer layers are respectively arranged on the lifting plane and the limiting surface.

[0022] The beneficial effect of the above technical solution is that it is easy to protect the flange on the cylinder and avoid damaging the cylinder during the lifting process.

[0023] Furthermore, the mounting seat includes a mounting plate and a mounting block fixedly arranged on the mounting plate and used for hinged connection to the hanging member, and the mounting block is provided with a pin through-hole for the pin to pass through.

[0024] The beneficial effect of the above technical solution is that the arrangement of the mounting plate facilitates maintaining a constant distance between the hook structures, and the arrangement of the mounting block facilitates an articulated connection between the mounting block and the lifting member.

[0025] Furthermore, the mounting plate is a rectangular plate, and two hanging parts are provided. The two hanging parts are arranged on the edges of the rectangular plate of the mounting plate and are symmetrical about the center of the rectangular plate.

[0026] The beneficial effect of the above technical solution is that the rectangular plate has a simple structure and is conducive to reducing the overall size of the mounting seat and reducing the weight of the cylinder lifting device. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] The features and performance of the present invention are further described in detail below in conjunction with the embodiments.

[0035] In Embodiment 1 of the cylinder hoisting device of the present invention:

[0036] In this embodiment, the cylinder is hoisted by means of a hinged mounting seat and a hoisting member, and a hook structure and a hinged portion are provided on the hoisting member to facilitate connection and cooperation with the cylinder flange. At the hoisting station, the distance between the hoisting rope connection structure and the cylinder axis is smaller than the distance between the hinged portion and the cylinder axis. The hoisting rope also has a certain angle during hoisting. When the angle between the line connecting the hinged portion and the hoisting rope connection structure and the hoisting rope located outside the hoisting rope is less than 180 degrees, the hoisting rope will apply a torque to the hoisting rope connection structure, so that the hook structure will become tighter and tighter with the cylinder flange under the action of the hoisting rope, thereby facilitating hoisting.

[0037] like Figure 2As shown, the cylinder lifting device in this embodiment includes a mounting seat and a lifting member hingedly arranged on the mounting seat, and the lifting member is provided with a hook structure for stopping cooperation with the cylinder flange 12 on the cylinder 11, a hinged portion for hinged cooperation with the mounting member, and a lifting rope connecting structure for connecting with the lifting rope 4.

[0038] like Figure 2 , Figure 3 and Figure 4 As shown, specifically, the mounting seat includes a rectangular mounting plate 31 and a mounting block 32 fixedly connected to the mounting plate 31. There are two mounting blocks 32, and a notch is set on the narrow side of the mounting plate 31 and in the middle of the narrow side. The mounting block 32 is fixed on the notch by bolts. Each mounting block 32 has a two-petal mounting bracket, and the two mounting brackets are provided with a second pin through-hole for the pin to pass through, and there are two second pin through-holes on each mounting block 32, and the two second pin through-holes are arranged up and down. At this time, the connecting line of the centers of the two second pin through-holes is perpendicular to the plate surface of the mounting plate 31. Two weight-reducing holes are also arranged symmetrically along the center of the rectangular plate above the cylinder 11 of the mounting plate 31. The weight-reducing holes are circular, and when some electrical components are arranged on the hoisted cylinder 11, these electrical components can also be avoided through the weight-reducing holes.

[0039] like Figure 2 and Figure 3 As shown, the hoisting parts include a hoisting plate 21 and a hook plate 22. The hook plate 22 forms a hook structure. The hoisting plate 21 and the hook plate 22 are welded together, and the plate surface of the hoisting plate 21 and the plate surface of the hook plate 22 are perpendicular to each other. When hoisting, the hook plate 22 and the mounting plate 31 are parallel to each other, and a hoisting space is also formed between the hook plate 22 and the mounting plate 31. A hoisting plane for stopping the back of the cylinder flange 12 is formed on the hook plate 22, and a limit surface for stopping the front of the cylinder flange 12 is formed on the mounting plate 31. It is worth noting that in order to protect the cylinder flange 12, rubber pads 5 made of rubber are provided on the plate surfaces of the hook plate 22 and the mounting plate 31 facing the hoisting space.

[0040] The hinged part is arranged on the hanging plate 21. Specifically, in this embodiment, the hinged part is a first through hole of the pin, and two first through holes of the pin are arranged. The two first through holes of the pin correspond to the second through holes of the pin on the mounting block 32 respectively, so that the pin can be inserted to connect the two at the same time. That is to say, the hanging part is hingedly arranged on the mounting block 32. Since the mounting block 32 is arranged symmetrically along the center of the rectangular plate, the hanging part is also arranged symmetrically along the center of the rectangular plate. One of the first through holes of the pin and the corresponding second through hole of the pin constitute a hinge hole for installing the hinge shaft 24, and the remaining first through holes of the pin and the corresponding second through holes of the pin constitute a stop hole for installing the stop pin, so that the hanging part is kept in the hanging position. The lifting plate 21 includes a wide side section and a narrow side section, the width of the wide side section is greater than the width of the narrow side section, and the narrow side section also includes a gradient section with a gradually decreasing width and equal-width narrow side sections with equal width, wherein the lifting rope connection structure is located on the wide side section, the hinged part is located on the gradient section, and the hook plate 22 is fixed on the end of the equal-width narrow side section.

[0041] like Figure 2 As shown, the lifting rope connection structure is a lifting hole 23, and there are two lifting holes 23. When in the lifting position, the line connecting the centers of the two lifting holes 23 is perpendicular to the line connecting the centers of the two hinged holes. In the lifting position, the distance between the lifting rope connection structure and the axis of the cylinder 11 is less than the distance between the hinge and the axis of the cylinder 11, that is, in the lifting position, the inner lifting hole 23 inside the hinge is closer to the axis, so when lifting, the lifting rope 4 will be in a straight state, and the angle between the line connecting the centers of the hinge and the lifting hole 23 and the lifting rope 4 located outside the lifting rope 4 is less than 180 degrees. At this time, the end of the lifting rope 4 will apply a torque to the lifting hole 23, and the torque will cause the lifting hole 23 to rotate relative to the hinge, so that the hook plate 22 has a tendency to rotate toward the mounting plate 31, so that the cylinder flange 12 is clamped tighter and tighter between the hook plate 22 and the mounting plate 31.

[0042] like Figure 5 and Figure 6 As shown, when the cylinder 11 needs to be hoisted, first remove the pin shaft 24 at the bottom, and only rely on the pin shaft 24 at the upper end to hinge the hoisting part with the mounting part. At this time, the hoisting part can be rotated relative to the mounting seat. At this time, the hoisting part is rotated to the avoidance position so that the flange can pass through the space between the two hoisting parts. Then, the lifting rope 4 is connected to the hoisting hole 23, and the crane is connected for hoisting. At this time, the length of the lifting rope 4 needs to be controlled so that the angle between the line connecting the center of the hoisting hole 23 and the lifting rope 4 located outside the lifting rope 4 is less than 180 degrees, and then the cylinder 11 is hoisted. When the hoisting is completed, since the lifting rope 4 is not subjected to force, it is convenient to rotate the hoisting part to remove it. At this time, the retaining structure is the hoisting hole 23.

[0043] Of course, other lifting methods can also be used. First, remove the pin shaft 24 at the bottom, and only rely on the pin shaft 24 at the upper end to hinge the lifting member and the mounting seat. At this time, the hook structure can rotate relative to the mounting seat. At this time, rotate the hook structure to the avoidance position so that the flange can pass through the space between the two lifting members. Then connect the lifting rope 4 to the lifting hole 23, and then install the pin shaft 24 at the bottom in the pin shaft through hole and the hinge hole. At this time, the lifting member and the mounting seat can no longer rotate relative to each other, and connect the crane for lifting. At this time, the length of the lifting rope 4 has nothing to do with whether the lifting can be completed. At this time, one of the two hinge holes is a rotating hinge hole, and the other is a stop hinge hole. The stop hinge hole also constitutes a retaining structure.

[0044] In Example 2 of the cylinder lifting device of the present invention: Regarding the setting of the mounting plate, this embodiment proposes a new arrangement form. Different from Example 1, the mounting plate in this embodiment is set as a circular plate, and a plurality of lifting parts are arranged on the circumferential surface of the mounting plate, which are respectively used to lift different positions of the flange on the cylinder.

[0045] In Example 3 of the cylinder lifting device of the present invention: Regarding the setting of the mounting seat, this embodiment proposes a new arrangement form. Different from Example 1, in this embodiment, a mounting block is no longer separately provided, and a mounting bracket is integrally formed on the mounting plate.

[0046] In the embodiment 4 of the cylinder hoisting device of the present invention: for the setting of the hook structure and the mounting seat, this embodiment proposes a new arrangement form. Different from the embodiment 1, in this embodiment, a buffer pad is only provided on the hook structure. Of course, in other embodiments, a buffer pad may be provided only on the mounting seat. In other embodiments, no buffer pad may be provided on both the hook structure and the mounting seat.

[0047] In Example 5 of the cylinder lifting device of the present invention: Regarding the setting of the hook structure, this embodiment proposes a new arrangement form. Different from Example 1, the lifting part in this embodiment includes a hook block, which is overlapped with the flange on the cylinder through a surface on the hook block.

[0048] In Example 6 of the cylinder lifting device of the present invention: Regarding the setting of the first through hole of the pin and the second through hole of the pin, this embodiment proposes a new arrangement form. Different from Example 1, in this embodiment, the first through hole of the pin and the second through hole of the pin are arranged at an angle when the lifting component is in the lifting station.

[0049] In Example 7 of the cylinder lifting device of the present invention: Regarding the setting of the number of pin shaft perforations, this embodiment proposes a new arrangement form. Different from Example 1, in this embodiment, the pin shaft perforations are set to three. Of course, in other embodiments, the pin shaft perforations can also be set to other numbers greater than two, such as four, five or other numbers.

[0050] In Example 8 of the cylinder lifting device of the present invention: Regarding the setting of the lifting plate, this embodiment proposes a new arrangement form. Different from Example 1, the lifting plate in this embodiment is a rectangular plate, and an avoidance groove for avoiding the lifting plate is provided on the mounting seat.

[0051] In the embodiment 9 of the cylinder hoisting device of the present invention: for the arrangement of the hoisting member, this embodiment proposes a new arrangement form, and the difference from the embodiment 1 is that only one hoisting hole is arranged on the hoisting member in this embodiment. Of course, in other embodiments, multiple hoisting holes may also be arranged, and the hoisting holes may be three, four or other numbers greater than two.

[0052] In Example 10 of the cylinder lifting device of the present invention: Regarding the setting of the lifting parts, this embodiment proposes a new arrangement form. Different from Example 1, the lifting parts in this embodiment are no longer set as lifting holes but as lifting hooks.

[0053] In Example 11 of the cylinder lifting device of the present invention: Regarding the setting of the lifting parts, this embodiment proposes a new arrangement form. Different from Example 1, in this embodiment, a plurality of lifting holes are arranged on the lifting parts, and the distance between each lifting hole and the cylinder axis is smaller than the distance between the hinge part and the cylinder axis.
