Description

Technical Field

[0001] This invention relates to the field of transformer installation technology, and in particular to a transformer lifting and installation device. Background Technology

[0002] During outdoor transformer installation, cranes are typically used to hoist the transformer to the installation height via suspension, thus completing the installation work. However, when installing transformers in underground factories or other spaces, space constraints make it difficult for large cranes to access the site. In such cases, hydraulic lifting equipment or manual labor is usually used for installation. However, hydraulic lifting equipment is not small in size to accommodate the size of the transformer and different installation heights, and it lacks a shrinking function, making it inconvenient to move and resulting in low installation efficiency. Summary of the Invention

[0003] The main objective of this invention is to provide a transformer lifting and installation device, which aims to solve the existing technical problems.

[0004] To achieve the above objectives, the present invention provides a transformer lifting and installation device, comprising:

[0005] The base support has a cross-shaped structure, with guide frames that are hinged around it at equal intervals. The bottom of the connection end between the base support and the guide frames is provided with a support plate.

[0006] The lifting assembly includes four lower supports, the lower parts of which are movably fitted onto guide frames at corresponding positions, and a lifting structure at the top for lifting the transformer to the installation device. The bottom of each lower support is provided with a movable component.

[0007] The load-bearing component, located between the four-way distributed lifting components and detachably connected to each lifting component, is used to carry the transformer.

[0008] Furthermore, the lower support column slides along the guide frame onto the bottom support, and the guide frame can rotate upwards to be parallel to the lower support column. The two are connected by locking bolts.

[0009] Furthermore, the lifting structure includes an upper support column, which is connected to a lower support column via an internal hydraulic rod. A movable block that can move between the upper and lower support columns is movably sleeved on the upper support column. The movable block is driven by an external hydraulic rod and has a through groove.

[0010] Furthermore, the bearing assembly includes four bearing plates, which are spliced ​​together to form a rectangular plate structure. Adjacent bearing plates are movably connected. Each bearing plate has a movable block with detachable support plates at both ends. The lower surface of the bearing plate slides against the support plate. One end of the bearing plate passes through the movable block, and the middle of this end is connected by positioning bolts that pass through the support plate, the movable block, and the bearing plate in sequence.

[0011] Furthermore, the bearing assembly also includes a rotating disk mounted on a base support, the rotating disk being slidably connected to a branch end of the base support, a sliding groove for the rotating disk to move being provided on the base support, a telescopic cylinder being provided on the rotating disk, a mounting frame being provided on the top of the telescopic cylinder, a toothed roller being provided inside the mounting frame, and the toothed roller being driven to rotate by a drive structure.

[0012] The bottom surface of the bearing plate is provided with a toothed groove that meshes with the toothed roller.

[0013] Furthermore, each of the carrier plates is provided with a connecting component for connecting the four-way separated carrier plates. The connecting component includes a clamping plate that is rotatably connected to the carrier plate at one end. The carrier plate is provided with a protrusion that is connected to an adjacent clamping plate on one side, and the surface of the carrier plate is provided with a groove that is adapted to the clamping plate. The clamping plate is a telescopic structure.

[0014] Furthermore, the top of the upper support column is provided with a rotating disk, the rotating disk is provided with a lifting cylinder, and the top of the lifting cylinder is provided with horizontally distributed lifting support rods, which are used to lift and remove the transformer by contacting the convex edge on the transformer after the transformer is lifted to the mounting platform.

[0015] Furthermore, the support plates corresponding to the four bearing plates are divided into a first support plate and a second support plate arranged symmetrically. The connecting ends of adjacent first support plates and second support plates are movably inserted. The second support plate includes a first support plate and a second support plate. The end of the first support plate is connected to the second support plate through a rotation locking structure. A support block is provided at the bottom of the connecting end of the first support plate and the second support plate. A sliding wheel is provided on the bottom of the second support plate away from the connecting end of the first support plate.

[0016] The first support plate is longer than the second support plate.

[0017] Furthermore, during the process of unloading the transformer from the load-bearing assembly, a set of lower support columns with lifting struts at the top can slide along the guide frame to adjust the spacing between the symmetrical lower support columns. One of the lower support columns in another set can slide along the guide frame to the corresponding load-bearing assembly to the far end, and the other lower support column can slide to the far end and then move down.

[0033] Please see Figure 1 and 2 The present invention provides a transformer lifting and installation device, comprising:

[0034] The base support 100 has a cross-shaped structure, and guide frames 101 are hinged around it at equal intervals. A support plate 102 is provided at the bottom of the connection end between the base support 100 and the guide frames 101.

[0035] The lifting assembly 200 includes four lower support columns 201, the lower part of which is movably sleeved on the guide frame 101 at the corresponding position, and the top is provided with a lifting structure for lifting the transformer to the installation device. The bottom of the lower support column 201 is provided with a movable part 202; wherein, the movable part 202 may be a caster wheel.

[0036] The load-bearing component 300 is disposed between the four-way distributed lifting components 200 and is detachably connected to each lifting component 200 for carrying the transformer.

[0037] The present invention, through the lifting components 200 that can move towards each other in the middle, the guide frame 101 that can be folded upward and retracted, and the detachable load-bearing components 300, helps to reduce the overall volume before entering a confined space, making it easy to move into the designated installation position, and then quickly unfold and assemble. According to the installation requirements, the overall posture can be adjusted in a timely manner, making it easy to move and improving installation efficiency.

[0038] In one embodiment, please refer to Figure 2 The lower support column 201 slides along the guide frame 101 onto the bottom support 100. The guide frame 101 can rotate upwards to be parallel to the lower support column 201. The two are connected by locking bolts.

[0039] When moving this device, first slide the lower support column 201 outward to remove the bearing component 300. Then slide the four-way lower support column 201 along the guide frame 101 towards the center until the lower support column 201 slides onto the bottom support 100. At this time, rotate the four-way guide frame 101 upward by 90° and connect it to the lower support column 201 through the locking bolts that pass through the guide frame 101. This binds the guide frame 101 to one side of the lower support column 201, reducing the overall volume before entering a narrow space, making it easier to move to the designated installation position. This facilitates movement and improves installation efficiency.

[0040] In one embodiment, the lifting structure includes an upper support column 203, which is connected to a lower support column 201 via an inner hydraulic rod 204. A movable block 205, which can move between the upper support column 203 and the lower support column 201, is movably sleeved on the upper support column 203. The movable block 205 is driven by an outer hydraulic rod 206 and has a through groove.

[0041] The upper support column 203 and the lower support column 201 are connected by an internal hydraulic rod 204. The maximum distance that the movable block 205 can rise can be adjusted according to the actual installation requirements. In specific operation, the movable block 205 is driven to move up and down to the lowest position on the lower support column 201 by the external hydraulic rod 206. After the transformer is placed on the bearing component 300, the movable block 205 is driven by the external hydraulic rod 206 to move the bearing component 300 upward. At this time, the upper support column 203 and the lower support column 201 are connected together. After the movable block 205 moves onto the upper support column 203, if a higher installation height is required, the height of the upper support column 203 can be adjusted by the internal hydraulic rod 204 to adapt to different installation heights and improve the applicability of the device.

[0042] In one embodiment, the support assembly 300 includes four support plates 301, which are spliced ​​together to form a rectangular plate structure. Adjacent support plates 301 are movably connected to each other. Each support plate 301 has a movable block 205 with detachable support plates at both ends. The lower surface of the support plate 301 is slidably attached to the support plate. One end of the support plate 301 passes through the movable block 205, and the middle of this end is connected by a positioning bolt 305 that passes through the support plate, the movable block 205 and the support plate 301 in sequence.

[0043] Specifically, the connecting ends of the support plate 301 are provided with protruding edges 3011 and slots. One end of the support plate is inserted into the movable block 205 through an integrally formed protrusion.

[0044] During installation, the middle part of the bearing plate 301 is connected to the movable block 205 and fixed by the positioning bolts 305 screwed in from below. This drives the four-way lower support columns 201 to move towards the center until the four bearing plates 301 are joined together to form a bearing surface. The lifting assembly 200 then moves the bearing plates 301 to achieve the lifting and installation of the transformer. During disassembly, the bearing plates 301 and the support plates are removed in sequence. The operation is simple and quick.

[0045] In one embodiment, the supporting component 300 further includes a rotating disk 306 disposed on the base support 100. The rotating disk 306 is slidably connected to the branch end of the base support 100. The base support 100 has a sliding groove 1001 for the rotating disk 306 to move. The rotating disk 306 is provided with a telescopic cylinder 307. The top of the telescopic cylinder 307 is provided with a mounting frame 308. The mounting frame 308 is provided with a toothed roller 309. The toothed roller 309 is driven to rotate by a driving structure 310.

[0046] The bottom surface of the bearing plate 301 is provided with a toothed groove 3012 that meshes with the toothed roller 309.

[0047] After the lifting assembly 200 lifts the support plate 301 to be flush with the mounting platform (not shown in the figure) for installing the transformer, the lower support column 201 on the side closest to the mounting platform is moved outward to detach from the assembly. During the detachment process, the support plate 301 connected to it is kept separate, so that the four support plates 301 remain intact. Then, the telescopic cylinder 307 drives the toothed roller 309 to move upward and engage with the support plate 301 (at this time, the rotating disk 306 moves outward along the slide groove 1001 to the farthest end), driving the toothed roller 309 to rotate, so that the support plate 301 slides along the support plate onto the mounting platform until more than four-fifths of the support plate 301 containing the transformer is moved onto the mounting platform and stops. The specific position can be selected according to the actual situation, but it is necessary to ensure that the support plate 301 does not detach from the support plate, thereby moving the transformer onto the mounting platform.

[0048] In one embodiment, each support plate 301 is provided with a connecting component 302 for connecting the four-way separated support plates 301. The connecting component 302 includes a clamping plate 3021 with one end rotatably connected to the support plate 301. The support plate 301 is provided with a protrusion 3022 corresponding to the clamping plate 3021 on one side, and the surface of the support plate 301 is provided with a groove adapted to the clamping plate 3021. The clamping plate 3021 is a telescopic structure.

[0049] To meet the installation requirements of transformers of different sizes, the bearing surfaces that the four bearing plates 301 can support are adjusted in a timely manner. Specifically, by sliding the four-way lower support column 201 outward at equal distances along the guide frame 101, the clamping plate 3021 is taken out and extended accordingly, and the separated bearing plates 301 are connected to each other. When placing the transformer, the transformer can be placed in the middle position of the assembled bearing plates 301.

[0050] In one embodiment, the top of the upper support column 203 is provided with a rotating disk 208, and the rotating disk 208 is provided with a lifting cylinder 207. The top of the lifting cylinder 207 is provided with horizontally distributed lifting support rods 209, which are used to lift and remove the transformer after it is lifted to the mounting platform and contacts the convex edge on the transformer. The rotating disk 208 is an electric disk.

[0051] After the assembled support plate 301 containing the transformer is moved to the mounting platform, the transformer is lifted upward by contacting the lifting support rods 209 on both sides with the convex edge on the transformer and using the lifting cylinder 207 to detach the transformer from the support plate 301. After the support plate 301 is reset and detached from the mounting platform, the transformer is placed on the mounting platform to complete the installation. The operation is simple and improves the installation efficiency.

[0052] In one embodiment, the support plates corresponding to the four bearing plates 301 are divided into a first support plate 303 and a second support plate 304 arranged symmetrically. The connecting ends of adjacent first support plates 303 and second support plates 304 are movably inserted. The second support plate 304 includes a first support plate 3041 and a second support plate 3042. The end of the first support plate 3041 is connected to the second support plate 3042 through a rotation locking structure 3045. A support block 3044 is provided at the bottom of the connecting end of the first support plate 3041 and the second support plate 3042. A sliding wheel 3043 is provided on the side of the bottom of the second support plate 3042 away from the connecting end of the first support plate 3041.

[0053] The length of the first support plate 3041 is greater than that of the second support plate 3042.

[0054] After the lifting assembly 200 lifts the bearing plate 301 to be flush with the mounting platform (not shown in the figure) for installing the transformer, and after the transformer is moved onto the mounting platform, the rotation locking structure 3045 is released. At this time, the two lower support columns 201 connected to the first support plate 303 are disengaged from the outside. According to the size of the transformer, the two lower support columns 201 connected to the second support plate 304 are moved along the guide frame 101. At this time, the first support plate 3041 and the second support plate 3042 rotate, and the lifting rods 209 on the upper support column 203 move accordingly, so that the spacing between the lifting rods 209 is adjusted, thereby meeting the subsequent hoisting operations of transformers of different sizes and improving the applicability of the device.

[0055] In one embodiment, during the process of unloading the transformer from the bearing assembly 300, a set of lower support columns 201 with lifting support rods 209 at the top can slide along the guide frame 101 to adjust the spacing between the symmetrical lower support columns 201. One of the other set of lower support columns 201 drives the corresponding connected bearing assembly 300 to slide to the far end along the guide frame 101, and the other lower support column 201 slides to the far end and then moves down.

[0056] In one embodiment, the rotation locking structure 3045 includes a rotating shaft 30451 that passes through and connects the first support plate 303 and the second support plate 304, and an arc-shaped magnet block 30452. The arc-shaped magnet block 30452 is embedded in a shaft hole opened on the first support plate 303, and the outer surface of the rotating shaft 30451 is in contact with the arc-shaped magnet block 30452. Specifically, the arc-shaped electromagnet 30452 is electrically connected to the electrical control equipment. When the arc-shaped electromagnet 30452 is energized, it generates a magnetic attraction force on the rotating shaft 30451, and the first support plate 303 and the second support plate 304 cannot rotate. When the arc-shaped electromagnet 30452 is de-energized, the first support plate 303 and the second support plate 304 can rotate.

[0057] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
