Description

Technical Field

[0001] The present invention relates to the technical field of hoisting large equipment, and particularly relates to a gantry hanger for a prefabricated cabin substation and a hoisting method thereof. Background Art

[0002] A prefabricated cabin substation is a type of substation that adopts a prefabricated cabin structure and integrates the main equipment of the substation (such as transformers, high-voltage switch cabinets, secondary protection equipment, etc.) into one. Its remarkable features include high integration, modularization, and factory production. The prefabricated cabin substation completes the production, assembly, wiring, and preliminary commissioning of all main equipment in the factory through a fully automated production line, and then is transported to the site as a whole unit for simple installation and commissioning before it can be put into operation. For example, the existing public document CN116667205A - Prefabricated Cabin Substation discloses a prefabricated cabin substation.

[0003] Because the prefabricated cabin substation is a highly integrated electrical equipment, its overall weight is relatively large. Therefore, when transporting the prefabricated cabin substation, workers need to use a gantry hanger to hoist the prefabricated cabin substation. For example, the existing public documents CN115009988A - A Gantry Hanger for a Prefabricated Cabin Substation and Its Hoisting and CN216583825U - A Mobile Gantry Hanger for a Substation both disclose a gantry hanger for substation hoisting. Although the existing gantry hanger can realize the hoisting of the substation, the existing gantry hanger still has the following deficiencies in actual use:

[0004] 1. When the existing gantry hanger is in use, in order to ensure the stability of substation hoisting, workers need to first tie up the entire substation with a support towing rope, and then workers hang the support towing rope through the gantry hanger to achieve hoisting. However, in such a hoisting method, workers need to climb and tie up on the substation, and the overall operation is complex and the labor intensity is relatively large.

[0005] 2. When workers tie up the substation with the support towing rope, when the support towing rope on one side of the substation is tightened and is arranged in a triangular shape as a whole, this causes the position where the upper end of the substation contacts the support towing rope to be too concentrated, and the force on the upper end of the substation is also relatively concentrated. This leads to low bundling stability of the substation on the one hand, and on the other hand, the support towing rope will also cause damage to the substation due to friction.

[0006] Therefore, it is necessary to improve the existing technology to solve the above technical problems. Summary of the Invention

[0007] The purpose of this section is to outline some aspects of the embodiments of the present invention and briefly introduce some preferred embodiments. In this section, as well as in the abstract and the title of the present application, some simplifications or omissions may be made to avoid obscuring the purpose of this section, the abstract, and the title. However, such simplifications or omissions shall not be used to limit the scope of the present invention.

[0008] In view of the problem that when the above-mentioned existing gantry hanger is used for hoisting a prefabricated cabin type substation, it is necessary for the staff to manually tie the supporting towing ropes to the outside of the substation, which has complex operations and high labor intensity, a gantry hanger for a prefabricated cabin type substation is proposed.

[0009] To solve the above technical problems, the present invention provides the following technical solution: A gantry hanger for a prefabricated cabin type substation includes a bundling mechanism, which includes a guiding component, a bundling component, a fixing component, and a driving component; and a hoisting mechanism arranged outside the bundling mechanism, which includes a gantry and a moving component fitted on the upper cross bar of the gantry. A hook is fixedly provided at the lower end of the total towing rope fitted on the moving component; There are two groups of guiding components arranged in parallel as a group, and the two groups of guiding components are arranged on both sides of the fixing component with a 180° rotation. The two bundling components are symmetrically arranged on both sides of the fixing component; The bundling component includes two winding rollers and two supporting towing ropes. The two winding rollers are coaxially arranged and fixedly sleeved on the same second rotating column. The two supporting towing ropes are respectively wound around the two winding rollers, and one end of each of the two supporting towing ropes is guided in direction through the two guiding components of the same group. Both ends of the second rotating column are rotatably connected to the fixed seat through rolling bearings. A first bevel gear is fixedly sleeved on the second rotating column between the two winding rollers; The fixing component includes an upper cover plate, a lower cover plate, and a fitting frame. The upper cover plate and the lower cover plate are arranged vertically in alignment, and one end of the guiding component is respectively rotatably connected to the upper cover plate and the lower cover plate. The fixed seat is fixedly connected to the top surface of the upper cover plate by bolts; The driving component includes a second motor, a third rotating column, and a gear column coaxially arranged from top to bottom. The output shaft fitted on the output end of the second motor drives the gear column to rotate through the third rotating column. The rotation of the gear column is used to synchronously drive the two guiding components of the same group to rotate towards or away from each other. A fourth gear disc is fixedly sleeved on the third rotating column, and a second gear disc is meshed on both sides of the fourth gear disc. The second gear disc is fixedly sleeved on the fifth rotating column. The lower end of the fifth rotating column is slidably sleeved in the first convex groove on the top surface of the upper cover plate. At the same time, a second bevel gear is fixedly provided at the upper end of the fifth rotating column. The two second bevel gears are respectively meshed with the two first bevel gears.

[0010] The beneficial effects of the present invention are as follows: when the gantry hanger is in use, after the bundling mechanism moves to directly above the transformer box, the output shaft can drive the third rotating column to rotate through the operation of the second motor, thereby realizing the rotation of the fourth gear plate. Because of the meshing arrangement of the fourth gear plate and the second gear plate and the meshing arrangement of the first bevel gear and the second bevel gear, the winding rollers on the two bundling components can rotate synchronously, thereby realizing the synchronous retraction and release of multiple branch traction ropes, so that the staff can bundle the branch traction ropes to the substation without climbing the substation, and tighten the branch traction ropes for lifting after the bundling is completed. This design is simple to operate, does not require the staff to perform climbing operations when bundling the substation, and effectively reduces the labor intensity of the staff.

[0016] In view of the problem that the existing gantry hanger has unreasonable bundling during the hoisting of the substation, which is likely to cause damage to the substation, the gantry hanger for a prefabricated cabin substation of the present invention is further preferably improved. Among them: the guiding assembly includes a rotating disc, a guiding rod, a screw rod and a movable rod. One end of the guiding rod is fixedly arranged on the side wall of the rotating disc. First toothed discs are symmetrically fixedly arranged at both ends of the rotating disc, and a first rotating column fixedly arranged in the rotating disc penetrates through the two first toothed discs.

[0019] Another beneficial effect of the present invention is that when the gantry hanger is in use, the supporting towing rope passes through the guiding groove on the guiding rod, and the guiding rod can guide the supporting towing rope in terms of direction. By adjusting the included angle between the two guiding assemblies in the same group, the position of the supporting towing rope in the horizontal direction can be adjusted. By setting the movable rod to move relative to the guiding rod, the position of the supporting towing rope can be adjusted according to the size of the substation. The above setting method can adjust the position of the supporting towing rope and the bundling force-bearing point according to the size of the substation, and the hoisting stability is more stable and the damage to the substation is effectively reduced, and the overall practicability is good.

[0045] Embodiment 1

[0046] Referring to Figure 1 and Figure 2 , this is the first embodiment of the present invention. This embodiment provides a gantry hanger for a prefabricated cabin-type substation. When this gantry hanger is in use, the bundling mechanism 100 fits on the top surface of the cabin-type substation to bind the cabin-type substation, and the hoisting mechanism 200 is used to drive the bundling mechanism 100 to displace the cabin-type substation in the horizontal direction.

[0047] Specifically, it includes a bundling mechanism 100, which includes a guiding component 101, a bundling component 102, a fixing component 103, and a driving component 104; and a hoisting mechanism 200 arranged outside the bundling mechanism 100, which includes a gantry 201 and a moving component 202 fitted on the upper crossbar of the gantry 201. A hook 202b is fixedly provided at the lower end of the total towing rope 202a fitted on the moving component 202. The total towing rope 202a is used to lift the bundling mechanism 100 in height. The moving component 202 includes an action of moving the total towing rope 202a in the vertical direction and an action of driving the bundling mechanism 100 to move horizontally on the crossbar of the gantry 201. Driving devices are provided at the bottoms of the two vertical rods of the gantry 201, so as to realize the movement of the entire gantry hoist in the horizontal direction; There are two groups in total with two parallel guiding components 101 as a group, and the two groups of guiding components 101 are arranged on both sides of the fixing component 103 after rotating 180°. The two bundling components 102 are symmetrically arranged on both sides of the fixing component 103. The guiding component 101 is used for guiding the lowering position of the towing rope 102c, and the bundling component 102 is used for bundling and fixing during the hoisting of the substation.

[0048] See details in Figure 2 、 Figure 5 、 Figure 6 、 Figure 8 and Figure 9 As shown in

[0049] , the bundling component 102 includes two winding rollers 102a and two towing ropes 102c. The two winding rollers 102a are coaxially arranged and fixedly sleeved on the same second rotating column 102d. The two towing ropes 102c are respectively wound around the two winding rollers 102a, and one ends of the two towing ropes 102c are respectively guided in direction through the two guiding components 101 of the same group. The two ends of the second rotating column 102d are respectively rotatably connected to the fixed seat 102b through rolling bearings. A first bevel gear 102d-1 is fixedly sleeved on the second rotating column 102d at the position between the two winding rollers 102a. This setting can realize the winding and unwinding of the towing rope 102c on the winding roller 102a by the rotation of the winding roller 102a during use;The driving assembly 104 includes a second motor 104a, a third rotating column 104c, and a gear column 104d that are coaxially arranged from top to bottom. The second motor 104a is fixedly connected to the top surface of the upper cover plate 103a through a fixing bracket 104a-1. The output shaft 104b fitted on the output end of the second motor 104a drives the gear column 104d to rotate through the third rotating column 104c. The rotation of the gear column 104d is used to synchronously drive the two guiding assemblies 101 so that the two guiding assemblies 101 in the same group rotate towards or away from each other. A fourth gear disc 104c-2 is fixedly sleeved on the third rotating column 104c, and second gear discs 104e are meshed on both sides of the fourth gear disc 104c-2. The second gear discs 104e are fixedly sleeved on fifth rotating columns 104e-1. The lower ends of the fifth rotating columns 104e-1 are slidably sleeved in the first convex grooves 103a-3 on the top surface of the upper cover plate 103a, thereby realizing the limited rotation of the fifth rotating columns 104e-1. At the same time, second bevel gears 104e-2 are fixedly provided at the upper ends of the fifth rotating columns 104e-1, and the two second bevel gears 104e-2 are respectively meshed with two first bevel gears 102d-1;

[0050] When the above settings are used, by rotating the second motor 104a, the output shaft 104b can drive the gear column 104d to rotate through the third rotating column 104c, so that the two guiding assemblies 101 can be synchronously driven, thereby realizing the guidance of the lowering position of the support towing rope 102c; in addition, by operating the second motor 104a, the third rotating column 104c can drive the fourth gear disc 104c-2 to rotate. Through the meshing of the second gear discs 104e, the second bevel gears 104e-2 can drive the first bevel gears 102d-1 to rotate. The rotation of the first bevel gears 102d-1 combined with the transmission of the second rotating columns 102d can realize the rotation of the winding rollers 102a. The rotation of the winding rollers 102a can realize the winding and lowering of the support towing ropes 102c.

[0051] See details Figure 1 、 Figure 2 、 Figure 6 、 Figure 8 and Figure 9As shown in the figure, the fixing component 103 includes an upper cover plate 103a, a lower cover plate 103b and a fitting frame 103c. The upper cover plate 103a and the lower cover plate 103b are arranged vertically aligned, and one end of the guiding component 101 is rotatably connected to the upper cover plate 103a and the lower cover plate 103b respectively. The fixing seat 102b is fixedly connected to the top surface of the upper cover plate 103a by bolts to achieve a detachable connection between the fixing seat 102b and the upper cover plate 103a. On both sides of the middle part of the upper cover plate 103a, L-shaped plates 103a-1 are symmetrically fixed. The lower ends of the L-shaped plates 103a-1 extend below the lower cover plate 103b. The horizontal plates at the lower ends of the L-shaped plates 103a-1 are fixedly connected to the lower cover plate 103b by bolts. On one side surface of the vertical plate of the L-shaped plate 103a-1, a first connecting plate 103a-2 extends outward and is fixed, thereby achieving a detachable connection between the upper cover plate 103a and the lower cover plate 103b.

[0052] The fitting frame 103c is arranged in an inverted U shape. At the lower ends of the two vertical plates of the fitting frame 103c, U-shaped clamping plates 103c-1 sleeved on the first connecting plate 103a-2 are fixed. The U-shaped clamping plates 103c-1 and the first connecting plate 103a-2 are fixed in cooperation by bolts, thereby achieving a detachable connection between the fitting frame 103c and the first connecting plate 103a-2.

[0053] Furthermore, a hanging post 103c-2 is arranged in the middle of the top surface of the fitting frame 103c. The two ends of the hanging post 103c-2 are respectively fixedly connected to the top surface of the fitting frame 103c through second connecting plates 103c-3. The hanging post 103c-2 is used for the hanging of the hook 202b. This setting can achieve a detachable connection between the bundling mechanism 100 and the lifting mechanism 200. Thus, when lifting a small device that does not require the bundling mechanism 100, it can be directly lifted by the lifting mechanism 200.

[0054] In addition, it should be noted that the device also includes a controller (not shown in the drawings). The controller is used to control each electrical component in this gantry crane. The controller is arranged at a position convenient for the staff to operate.

[0055] Embodiment 2

[0056] Referring to Figure 3 、 Figure 6 、 Figure 10 、 Figure 11 and Figure 12 This is the second embodiment of the present invention. Based on the previous embodiment, the difference is that in order for the driving component 103 to better drive the guiding component 101 and the bundling component 103, so as to better implement this device, an adjusting component 105 is proposed.

[0057] Specifically, the two adjustment components 105 are symmetrically arranged on both sides below the fourth toothed disc 104c-2, and the adjustment component 105 includes a T-shaped column 105a and an electromagnetic column 105b; a groove 104d-2 is opened on the top surface of the gear column 104d, and an inner ring tooth 104d-3 is fixedly arranged on the inner wall of the upper end of the groove 104d-2 along the circumferential direction, and a fourth rotating column 104d-1 is fixedly arranged in the middle of the bottom surface of the gear column 104d, and the fourth rotating column 104d-1 is rotatably sleeved on the lower cover plate 103b through a rolling bearing, so as to realize the gear column 104d on the lower cover plate 103b. The third rotating column 104c is fixedly provided with a third toothed disc 104c-1 meshing with the inner ring gear 104d-3 at the bottom end thereof, and a rectangular column 104c-3 is fixedly provided on the top surface of the third rotating column 104c. Meanwhile, a rectangular groove 104b-1 for the sliding sleeve of the rectangular column 104c-3 is provided on the bottom surface of the output shaft 104b. This arrangement can realize that the output shaft 104b drives the third rotating column 104c to rotate, and can realize that the rectangular column 104c-3 is equivalent to the output shaft 104b to move in the axial direction of the output shaft 104b;

[0058] The top surfaces of the upper cover plates 103a on both sides below the fourth toothed disc 104c-2 are symmetrically provided with second convex grooves 103a-4, and the T-shaped columns 105a are slidably sleeved in the second convex grooves 103a-4, and the electromagnetic columns 105b are embedded and fixed on the inner bottom surface of the second convex grooves 103a-4, and a magnet disk 105a-2 is fixed on the bottom surface of the T-shaped columns 105a, and the end surfaces of the magnet disk 105a-2 and the electromagnetic columns 105b that are close to each other are arranged in the same manner;

[0059] When the above arrangement is in use, when the electromagnetic column 105b is energized to generate magnetism, the magnet plate 105a-2 and the electromagnetic column 105b are repelled by each other, and the T-shaped column 105a moves upward to lift the fourth toothed plate 104c-2, and the meshing of the fourth toothed plate 104c-2 and the second toothed plate 104e is released. At the same time, the third toothed plate 104c-1 is meshed with the inner ring gear 104d-3, so that the gear column 104d is rotated under the operation of the second motor 104a, thereby realizing the rotation of the gear column 104d, thereby realizing the rotation of the gear column 104d. The guide component 101 is driven; when the electromagnetic column 105b is powered off, under the action of gravity, the third rotating column 104c moves downward, the third toothed disc 104c-1 disengages from the inner ring tooth 104d-3, and the fourth toothed disc 104c-2 re-engages with the second toothed disc 104e, thereby realizing the rotation of the second toothed disc 104e under the operation of the second motor 104a, and then realizing the driving of the binding component 102. The above-mentioned arrangement can realize the switching of the driving of the guide component 101 and the binding component 102.

[0060] Furthermore, a spring 104b-2 is slidably sleeved in the rectangular groove 104b-1 above the rectangular column 104c-3, and both ends of the spring 104b-2 are respectively fixed on the rectangular column 104c-3 and the output shaft 104b. The setting of the spring 104b-2 can better assist the coordination between the fourth gear disc 104c-2 and the second gear disc 104e.

[0061] Furthermore, a ball 105a-1 is embedded on the upper end surface of the T-shaped column 105a, and the vertical cross-section of the ball 105a-1 is partially exposed on the outside of the T-shaped column 105a, and the area of ​​the exposed part is smaller than the semicircle. The setting of the ball 105a-1 can reduce the friction of the T-shaped column 105a on the fourth toothed disc 104c-2 when the fourth toothed disc 104c-2 rotates.

[0062] Example 3

[0063] Reference Figure 2 , Figure 4 , Figure 6 , Figure 7 and Figure 8 , which is the third embodiment of the present invention, is based on any of the above embodiments, except that, in order to better implement the present device, the structure of the guide component 101 is concretized.

[0064] Specifically, the guide assembly 101 includes a rotating disk 101a, a guide rod 101b, a screw rod 101c and a movable rod 101d, one end of the guide rod 101b is fixed on the side wall of the rotating disk 101a, and the first toothed disks 101a-1 are symmetrically fixed at both ends of the rotating disk 101a, and the first rotating column 101a-2 fixed in the rotating disk 101a penetrates the two first toothed disks 101a-1, and the two ends of the first rotating column 101a-2 are respectively rotatably sleeved on the upper cover plate 103a and the lower cover plate 103b through rolling bearings; the first toothed disks 101a-1 on the same group of two guide assemblies 101 are meshed, and the diameters of the first toothed disks 101a-1 on the two guide assemblies 101 are different, and the first toothed disks 101a-1 with a larger diameter are meshed with the gear column 104d;

[0065] When the above arrangement is in use, the rotation of the first gear disc 101a-1 with a larger diameter in the same group can be realized through the rotation of the gear column 104d. Because the first gear discs 101a-1 in the two guide assemblies 101 in the same group are meshed, the two guide assemblies 101 in the same group can rotate towards or oppositely, thereby completing the adjustment of the angle between the two guide assemblies 101, thereby avoiding excessive concentration of force on the upper substation when the support traction rope 102c is hoisted.

[0066] The movable rod 101d is slidably sleeved on the free end of the guiding rod 101b. A fixing plate 101d-1 is fixedly arranged on the bottom surface of the movable rod 101d close to one side of the rotating disc 101a. A screw rod 101c is spirally sleeved on the fixing plate 101d-1, and one end of the screw rod 101c is fitted into the output end of the first motor 101c-1. The first motor 101c-1 is fixedly arranged on the bottom surface of the guiding rod 101b. The axis of the screw rod 101c is arranged parallel to the long side of the guiding rod 101b.

[0067] In the above setting, during use, by the operation of the first motor 101c-1, the rotation of the screw rod 101c can be realized. Because of the spiral fit between the screw rod 101c and the fixing plate 101d-1, the movable rod 101d can move relative to the guiding rod 101b in the axial direction of the screw rod 101c, so as to adjust the position where the supporting towing rope 102c is lowered according to the size of the substation.

[0068] Further, an L-shaped guiding groove 101b-1 is formed on the guiding rod 101b along the long side direction. The free end of the supporting towing rope 102c sequentially slides through the guiding groove 101b-1 and the end face of the movable rod 101d, and the free end of the supporting towing rope 102c extending outside the movable rod 101d is bundled into a bundling sleeve through a fixing buckle 102c-1, so as to realize better bundling of the supporting towing rope 102c with the substation.

[0069] Embodiment 4

[0070] This embodiment is the fourth embodiment of the present invention. This embodiment provides a hoisting method for a gantry hanger for a prefabricated substation. Specifically, the hoisting operation is carried out according to the following steps;

[0071] S1: Through the walking of the hoisting mechanism 200, the bundling mechanism 100 is moved to directly above the substation to be hoisted, and the bundling mechanism 100 is lowered and placed on the top surface of the substation. In order to avoid damage to the substation caused by the cooperation between the bundling mechanism 100 and the substation, in actual use, a protective pad can be added between the substation and the bundling mechanism 100;

[0072] S2: Adjust the included angle between the two guiding components 101 in the same group according to the size of the substation. At the same time, adjust the position of the movable rod 101d on the guiding rod 101b;

[0073] S3: After the adjustment is completed, the driving component 104 controls all the supporting towing ropes 102c to be released synchronously. After the release is completed, the staff binds the free ends of the supporting towing ropes 102c to the reserved bundling columns of the substation;

[0074] S4: After the bundling is completed, wind up the supporting towing ropes 102c to tighten the substation;

[0075] S5: Finally, the traveling of the hoisting mechanism 200 is performed to hoist the substation.
