Abstract
Description
Technical Field
[0001] This invention belongs to the field of prefabricated cabin hoisting, specifically relating to a method and auxiliary device for adjusting the center of gravity of a prefabricated cabin. Background Technology
[0002] Prefabricated modules play an indispensable and important role in the power grid as carriers of prefabricated substation electrical equipment. Prefabricated modules are characterized by standardization, modularization, and prefabrication. Manufacturers can customize specific dimensions according to the actual needs of the equipment cabinet to adapt to the installation and operation of the electrical equipment to be installed. As a result, with the accelerated pace of smart grid construction, the demand for prefabricated modules is also increasing rapidly.
[0003] The application process of the prefabricated module is as follows: first, multiple predetermined electrical devices are installed inside it, and then the prefabricated module is transported and hoisted to the predetermined location.
[0004] However, in practice, the above method has shortcomings: due to the needs of electrical layout, the positions of most of the prefabricated electrical equipment in the prefabricated cabin are biased to one side during normal operation, which causes the center of gravity of the prefabricated cabin to be biased to one side rather than the center of the prefabricated cabin. Therefore, there is a risk of slippage and overturning during transportation. Moreover, it is not possible to quickly determine the center of gravity of the prefabricated cabin for hoisting. Furthermore, if the determined center of gravity of the prefabricated cabin is not its actual center of gravity, it will lead to a serious hoisting accident. Summary of the Invention
[0005] In view of the shortcomings of the prior art, the present invention provides a method and auxiliary device for adjusting the center of gravity of a prefabricated cabin, which can quickly adjust the center of gravity of the prefabricated cabin to a predetermined position, thereby eliminating the related risks caused by the center of gravity being biased to one side during transportation and hoisting.
[0006] To achieve the above objectives, the present invention provides the following technical solution:
[0007] A method for adjusting the center of gravity of a prefabricated module, the prefabricated module having a base support and containing multiple predetermined electrical devices, characterized by comprising the following steps:
[0008] Step S1: Movably mount the equipment support plate on the base bracket so that the predetermined electrical equipment is located on the equipment support plate;
[0009] Step S2: Move the equipment support plate to the predetermined middle position and mechanically position the equipment support plate on the base bracket;
[0010] Step S3: Remove the mechanical positioning and move the equipment support plate to the predetermined final position.
[0011] Preferably, in step S1, a sliding straight guide rail is provided between the equipment carrier plate and the base support.
[0012] Furthermore, an extended straight guide rail is detachably provided, and the extended straight guide rail is connected to the sliding straight guide rail.
[0013] Furthermore, in step S2, the extended straight guide rail is of a predetermined length, and the end of the extended straight guide rail that is far away from the sliding straight guide rail is used as the stop end. An end sealing plate is set at either the open end or the stop end of the sliding straight guide rail. An obstruction baffle is detachably set on the sliding straight guide rail. The obstruction baffle and the end sealing plate clamp and position the equipment carrier plate.
[0014] Furthermore, the present invention also includes the following steps:
[0015] Step S4: Remove the extended straight guide rail and fix the equipment support plate on the sliding straight guide rail.
[0016] An auxiliary device for adjusting the center of gravity of a prefabricated cabin, characterized in that it comprises: a sliding straight guide rail, as described above; an equipment support plate, as described above; an obstruction baffle, as described above; and an end sealing plate, as described above.
[0017] Preferably, the sliding straight guide rail is fixed on the base support as described above, and the sliding straight guide rail is a grooved guide rail with at least one open end. The lower end of the equipment support plate has a sliding member that cooperates with the groove of the sliding straight guide rail. The two ends of the obstruction baffle are respectively connected by threads to the two sides of the groove of the sliding straight guide rail, and the plate body of the obstruction baffle is located at the opening of the groove of the sliding straight guide rail, forming a solid obstruction on the extension path of the sliding straight guide rail.
[0018] Furthermore, the moving part has a fixed frame and a moving wheel. The fixed frame is fixed to the lower end face of the equipment bearing plate, and the moving wheel is rotatably mounted on the fixed frame. The moving wheel engages with the groove of the sliding straight guide rail and rolls in contact with the bottom surface of the groove.
[0019] Furthermore, the present invention also includes an extended straight guide rail, which is the extended straight guide rail described above; the extension length of the sliding straight guide rail corresponds to the width of the equipment bearing plate, and the extended straight guide rail is a grooved guide rail with open ends, and the extended straight guide rail is threadedly connected to the open end of the sliding straight guide rail.
[0020] Furthermore, the bottom of the extended straight guide rail is threadedly connected to the base bracket.
[0021] Compared with the prior art, the beneficial effects of the present invention are:
[0022] 1. Because the method for adjusting the center of gravity of the prefabricated cabin of the present invention includes the following steps: First, an equipment support plate is movably set on the base support so that the predetermined electrical equipment is located on the equipment support plate; second, the equipment support plate is moved to a predetermined intermediate position and mechanically positioned on the base support; finally, the mechanical positioning is removed and the equipment support plate is moved to a predetermined final position. Therefore, the present invention can quickly adjust the center of gravity of the prefabricated cabin to a predetermined intermediate position. That is, during transportation and hoisting, the center of gravity of the prefabricated cabin can be located in the middle of the prefabricated cabin by moving the predetermined electrical equipment, thereby eliminating the related risks caused by the center of gravity being biased to one side during transportation and hoisting. After hoisting is completed, the predetermined electrical equipment is then adjusted to the predetermined final position when it is working normally.
[0023] 2. Because a sliding straight guide rail is provided between the equipment support plate and the base bracket in step S1 of the present invention, the present invention can move the predetermined electrical equipment more effortlessly and quickly.
[0024] 3. Because the extended straight guide rail is detachably provided in this invention and the extended straight guide rail is connected to the sliding straight guide rail, this invention can significantly extend the moving distance of the predetermined electrical equipment. Furthermore, the extended straight guide rail is detachable, has good portability, and is flexible in its installation.
[0025] 4. Because the extended straight guide rail of the present invention is of a predetermined length, the end of the extended straight guide rail away from the sliding straight guide rail is used as the stop end. An end sealing plate is detachably provided on the stop end, and an obstruction baffle is detachably provided on the sliding straight guide rail. The obstruction baffle and the end sealing plate clamp and position the equipment carrier plate. The predetermined length satisfies the following: when the end of the equipment carrier plate is located at the stop end, the center of gravity in the prefabricated cabin is located in the middle of the prefabricated cabin. Therefore, the predetermined electrical equipment of the present invention will not be displaced due to vibration during transportation and hoisting.
[0026] 5. Because the extended straight guide rail of the present invention is threaded to the base bracket at its bottom, the extended straight guide rail of the present invention can be securely installed, thereby further improving the movement stability of the intended electrical equipment.

Detailed Implementation
[0037] To make the technical means, creative features, objectives and effects of the present invention easier to understand, the following embodiments, in conjunction with the accompanying drawings, specifically illustrate a method for adjusting the center of gravity of a prefabricated cabin and an auxiliary device of the present invention. It should be noted that the description of these embodiments is for the purpose of helping to understand the present invention, but does not constitute a limitation of the present invention.
[0038] In this embodiment, the prefabricated cabin C has a base support A, and the prefabricated cabin C contains multiple predetermined electrical devices B, such as... Figure 2 As shown, the positions of multiple predetermined electrical devices B during normal operation are taken as predetermined final positions. All predetermined electrical devices B located at their predetermined final positions are offset to one side of the prefabricated cabin C. Therefore, during normal operation, the center of gravity of the prefabricated cabin C is offset to one side and not located in the center of the structure; as... Figure 3 As shown, in order to place the center of gravity of the prefabricated cabin C in the middle of the structure, the positions of multiple predetermined electrical devices B should be adjusted within the prefabricated cabin C to obtain a new position different from the predetermined final position, and this position is taken as the predetermined intermediate position.
[0039] like Figure 1 As shown, the method S100 for adjusting the center of gravity of the prefabricated cabin in this embodiment includes the following steps:
[0040] Step S1: Movably mount the equipment support plate on the base bracket A, so that the predetermined electrical equipment B is located on the equipment support plate.
[0041] In step S1, a sliding straight guide rail is provided between the equipment carrier plate and the base bracket A. Specifically, the sliding straight guide rail is fixedly installed on the base bracket A, and the predetermined electrical equipment B is detachably installed on the equipment carrier plate. The extension length of the sliding straight guide rail corresponds to the width of the equipment carrier plate. That is, when one end of the equipment carrier plate corresponds to one end of the sliding straight guide rail, the other end of the equipment carrier plate also corresponds to the other end of the sliding straight guide rail.
[0042] An extended straight guide rail is detachably installed on the base bracket A, and the extended straight guide rail is detachably connected to the sliding straight guide rail end.
[0043] Step S2: Move the equipment carrier plate to the predetermined intermediate position and mechanically position the equipment carrier plate on the base bracket A, that is, detachably assemble and fix the equipment carrier plate to the base bracket A when it is in the predetermined intermediate position.
[0044] The extended straight guide rail is of a predetermined length. The end of the extended straight guide rail that is far from the sliding straight guide rail is used as the stop end. An end sealing plate is set at either the open end or the stop end of the sliding straight guide rail. A blocking baffle is detachably set on the sliding straight guide rail. The blocking baffle and the end sealing plate clamp and position the equipment carrier plate. Specifically, the equipment mounting plate is moved from the sliding straight guide rail to the extended straight guide rail. The blocking baffle and the end sealing plate simultaneously limit the equipment carrier plate at both ends, thereby fixing the equipment carrier plate. At this time, the predetermined electrical equipment is located in the predetermined middle position.
[0045] Step S3: Remove the mechanical positioning and move the equipment support plate to the predetermined final position.
[0046] Specifically, the obstruction baffle is removed, and the mobile device carrier plate is returned to the sliding straight guide rail. At this point, the intended electrical equipment is in the intended final position.
[0047] Step S4: Remove the extended straight guide rail and fix the equipment support plate on the sliding straight guide rail.
[0048] Specifically, since the extension length of the sliding straight guide rail corresponds to the width of the equipment carrier plate, the equipment carrier plate is fixed on the sliding straight guide rail by setting closures at both ends of the sliding straight guide rail.
[0049] like Figures 4-6 As shown, a prefabricated cabin center of gravity adjustment auxiliary device 100 includes a sliding straight guide rail 1, an equipment bearing plate 2, an extended straight guide rail 3, an obstruction baffle 4, and an end sealing plate 5.
[0050] The sliding straight guide rail 1 is the sliding straight guide rail described above. The sliding straight guide rail 1 is fixed on the base bracket A as described above. The sliding straight guide rail 1 is a grooved guide rail with at least one open end. In this embodiment, the sliding straight guide rail 1 has a groove extending along its own extension direction. One end of the sliding straight guide rail 1 is closed and the other end is open. In this embodiment, the number of sliding straight guide rails 1 is four and they are parallel to each other.
[0051] The equipment support plate 2 is the aforementioned equipment support plate, and the lower end of the equipment support plate 2 has a track corresponding groove 21 and a sliding member 22.
[0052] Specifically, the track corresponding groove 21 corresponds to the groove of the sliding straight guide rail 1. In this embodiment, the number of track corresponding grooves 21 is four.
[0053] The slider 22 mates with the groove of the sliding guide rail 1, specifically, as shown in the example... Figure 7 As shown, the sliding member 22 has a fixed frame 221 and a movable wheel 222. The fixed frame 221 is fixed on the inner wall of the corresponding groove 21 of the track. The movable wheel 222 is rotatably mounted on the fixed frame 221. The movable wheel 222 cooperates with the groove of the sliding straight guide rail 1 and rolls in contact with the bottom surface of the groove, that is, it can roll along the extension direction of the groove, thereby driving the equipment support plate 2 to move linearly relative to the sliding straight guide rail 1.
[0054] The extended straight guide rail 3 is the extended straight guide rail described above. The extended straight guide rail 3 is a grooved guide rail with open ends. The extended straight guide rail 2 is threaded to the open end of the movable straight guide rail 1, and the bottom of the extended straight guide rail 3 is threaded to the base bracket 1. Specifically, a fixing screw S that is threaded to the base bracket A is provided near the stop end of the extended straight guide rail 3. The extended straight guide rail 3 is threaded to the sliding straight guide rail 1, and the grooves correspond to each other, thereby forming a continuous groove. The equipment carrier plate 2 can move along the continuous groove through the sliding member. In this embodiment, the corresponding ends of the sliding straight guide rail 1 and the extended straight guide rail are bolted together by the fixed angle iron I.
[0055] The obstruction baffle 4 is the aforementioned obstruction baffle. Both ends of the obstruction baffle 4 are respectively threaded and set on both sides of the groove of the sliding straight guide rail 1. The plate body of the obstruction baffle 4 is located at the opening of the groove of the sliding straight guide rail 1, forming a solid obstruction on the extension path of the sliding straight guide rail 1. In this embodiment, the obstruction baffle 4 is a "U" shaped plate, which is inverted and inserted into the sliding straight guide rail 1 above the groove, so that both ends of the obstruction baffle 4 are located on opposite sides of the sliding straight guide rail 1, and both ends have through holes. By correspondingly setting the fixing angle iron I on the sliding straight guide rail 1, and connecting it with bolts, the obstruction baffle 4 is fixed to the sliding straight guide rail 1.
[0056] The end sealing plate 5 is the end sealing plate mentioned above. It is fixed to the stop end by threaded connection. Specifically, it limits the equipment carrier plate 2 in one direction by obstructing the sliding member 22, while the limit in the other direction is achieved by the closed end of the sliding straight guide rail 1 or the obstructing baffle 4, thereby realizing the clamping and positioning of the equipment carrier plate 2.
[0057] The following describes the implementation process of the prefabricated cabin center of gravity adjustment auxiliary device 100 in the transportation, hoisting, and normal installation of the prefabricated cabin C, with reference to the embodiments:
[0058] The transportation and hoisting process of prefabricated module C: as follows Figure 8 As shown, an extended straight guide rail 3, which is continuously connected to the sliding straight guide rail 1, is set on the base bracket A. The equipment carrier plate 2 is moved on the sliding straight guide rail 1 and the extended straight guide rail 3. The equipment carrier plate 2 is fixed in the predetermined middle position by the obstruction baffle 4 and the end sealing plate 5. At this time, the center of gravity G of the prefabricated cabin is located in the middle of the prefabricated cabin C. Therefore, the center of gravity of the prefabricated cabin C is very easy to determine during transportation and hoisting, and the overall structure is stable.
[0059] The normal setup process for prefabricated module C: as follows Figure 9 As shown, the equipment carrier plate 2 is moved onto the sliding straight guide rail 1, and the equipment carrier plate 2 is fixed in the predetermined final position by the end sealing plate 5. At this time, the center of gravity G of the prefabricated cabin is located on one side of the prefabricated cabin C, which meets the requirements for the normal operation of the prefabricated cabin C.
[0060] The above embodiments are preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Various modifications or variations that can be made by those skilled in the art without creative effort within the scope of the appended claims are still within the scope of protection of this patent.
[0061] For example, in this embodiment, the equipment support plate 2 is fixed on the base bracket A by the obstruction baffle 4 and the end sealing plate 5. The extended straight guide rail 3 is required to be of a predetermined length. That is, the predetermined length is calculated and designed in advance based on the internal dimensions of the prefabricated cabin C and the fact that the center of gravity C of the prefabricated cabin is located in the middle of the prefabricated cabin C. In specific implementation, the predetermined length may not be designed in advance, but it may be measured on site and then the equipment support plate 2 is clamped and fixed by using two obstruction baffles 4 in conjunction with the fixed angle iron I.
