Description

Technical Field

[0001] This utility model relates to the technical field of substation construction equipment, specifically a box-type substation construction auxiliary lifting device. Background Technology

[0002] A prefabricated substation is an integrated power distribution device that organically combines high-voltage switchgear, transformers, and low-voltage power distribution equipment within a closed or semi-closed metal enclosure according to a specific wiring scheme. It possesses functions such as high-voltage control, voltage transformation, and low-voltage power distribution. Prefabricated substations are compact in structure and comprehensive in function, widely used in urban power grids, construction sites, mining operations, railways, ports, and temporary power supply scenarios, and are particularly suitable for meeting the needs of temporary outdoor power supply during engineering construction.

[0003] Mobile prefabricated substations, commonly used outdoors, play a vital role in engineering construction, mining, and large-scale temporary projects. They allow for flexible adjustment of power supply locations according to construction progress, facilitating project construction. Due to the phased nature of engineering projects, mobile prefabricated substations require frequent disassembly and relocation; therefore, their installation and dismantling efficiency significantly impacts construction progress. During installation and dismantling, the prefabricated substation is typically lifted as a whole using a hoisting method for easy transportation and relocation.

[0004] In existing technologies, prefabricated substations are typically hoisted using lifting lugs on their bases. These lugs are then connected to lifting ropes, and a crane is used for lifting. However, this hoisting method suffers from problems such as single-point force distribution and insufficient safety. During hoisting, the force is borne solely by the lifting lugs on the base, which can lead to excessive tension at a single point, potentially causing overloading or even deformation of the base and increasing safety hazards during the hoisting process. Therefore, we propose an auxiliary hoisting device for prefabricated substation construction. Utility Model Content

[0005] The purpose of this utility model is to provide an auxiliary lifting device for the construction of a prefabricated substation, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A construction auxiliary lifting device for a prefabricated substation includes a base plate located at the bottom of the prefabricated substation. The base plate provides foundation support and serves as the main load-bearing structure of the entire device. The bottom of the base plate has three rope grooves arranged equidistantly front to back. Each of the three rope grooves is equipped with a lifting rope, a portion of which passes through the rope groove. The three lifting ropes support the base plate, effectively distributing pressure and preventing deformation of the base plate.

[0008] The top of the base plate is provided with a frame-shaped limiting plate to prevent the box-type substation from moving left or right or forward or backward during the lifting process. Positioning components are provided on the top of the base plate and near the left and right sides. The positioning components are used to stabilize the relative position of the lifting rope and ensure that the force on the entire lifting device is uniform.

[0009] The positioning component includes two fixed columns arranged symmetrically front and back to support the strip fixing plate. The top of the two fixed columns is connected to the strip fixing plate, providing a foundation for fixing the suspension rope. The outer side of the strip fixing plate has three first arc-shaped grooves arranged equidistantly front and back to guide the suspension rope and ensure that the suspension rope can be subjected to uniform force and stable direction.

[0010] It also includes a lifting plate for connecting to the lifting equipment. The lifting plate is used to transfer the force of the lifting equipment to the lifting ropes and the base plate. The lifting plate has three connecting side rings on both the left and right sides, which are arranged at equal intervals. The connecting side rings are used to connect to the ends of the lifting ropes respectively and to evenly distribute the force on each lifting rope during the lifting process. The ends of the lifting ropes pass through the first arc-shaped groove and are connected to the corresponding connecting side rings. The three connecting side rings on the left are connected to the left ends of the three lifting ropes respectively, and the three connecting side rings on the right are connected to the right ends of the three lifting ropes respectively, thereby forming a stable lifting structure.

[0011] Preferably, the outer side of the frame-shaped limiting plate is threaded with multiple clamping threaded rods, and the inner end of each clamping threaded rod is rotatably connected to a circular pressure block. The circular pressure block is located inside the frame-shaped limiting plate. By tightening the multiple clamping threaded rods, the circular pressure block is pressed against the side of the box-type substation base, thereby fixing the position of the box-type substation and the base plate.

[0012] Preferably, the outer side of the strip-shaped fixed plate is provided with a detachable strip-shaped movable plate. The side of the strip-shaped movable plate near the strip-shaped fixed plate has three second arc-shaped grooves arranged at equal intervals. The lifting rope is pressed between the second arc-shaped grooves and the first arc-shaped grooves. The second arc-shaped grooves and the first arc-shaped grooves together form a clamping structure to press and fix the lifting rope, so that the position of the lifting rope and the two positioning components is relatively fixed, thereby fixing the relative position of the lifting rope and the base plate, effectively preventing the base plate from sliding left and right relative to the lifting rope during the lifting process.

[0013] Preferably, the outer side of the strip movable plate has two mounting holes arranged symmetrically front and back. The mounting holes are connected to fastening bolts. The fastening bolts ensure that the strip movable plate and the strip fixed plate are firmly connected and further enhance the fixing effect of the suspension rope.

[0014] Preferably, the outer side of the strip-shaped fixing plate has two threaded grooves, and the threaded ends of the two fastening bolts are respectively threaded into the two threaded grooves, so that the fastening bolts can be firmly installed on the strip-shaped fixing plate, thereby achieving reliable fixing of the strip-shaped movable plate.

[0015] Preferably, a lifting ring is provided at the center of the top of the lifting plate. The lifting ring is used to directly connect with the lifting equipment to evenly transmit the pulling force of the lifting equipment to the entire device, ensuring that the lifting process is stable and safe.

[0016] Preferably, the bottom four corners of the base plate are provided with anti-slip pads made of high-strength rubber to increase the stability of the device on the construction site and prevent the base plate from sliding or shifting due to wet or uneven ground.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. The auxiliary lifting device for the construction of this prefabricated substation, through the design of multiple rope grooves and the arrangement of lifting ropes at the bottom of the base plate, makes the stress on the base plate more uniform during the lifting process, avoiding the problem of deformation or damage to the base plate caused by single stress in the existing technology, thus improving safety and service life.

[0019] 2. The design of the positioning component of this box-type substation construction auxiliary lifting device further ensures the uniformity of force and positional stability of the lifting rope. Through the cooperation of the strip fixed plate and the strip movable plate, the lifting rope is fixed between the first arc groove and the second arc groove, which avoids the relative sliding between the bottom plate and the lifting rope during the lifting process, thereby improving the lifting accuracy and safety.

[0020] 3. This box-type substation construction auxiliary lifting device, through the design of multi-point force bearing and multi-component cooperation of the whole device, effectively solves the problems of single-point force bearing, low lifting efficiency and large safety hazards in the existing technology, reduces lifting risks and meets the requirements of safe lifting.

[0030] Please see Figures 1-6 This utility model provides a technical solution:

[0031] A construction auxiliary lifting device for a prefabricated substation includes a base plate 1, which is located at the bottom of the prefabricated substation and is used to provide foundation support and serve as the main load-bearing structure of the entire device. The bottom of the base plate 1 has three rope grooves 10 arranged at equal intervals front and back. Each of the three rope grooves 10 is equipped with a lifting rope 5, and a part of the lifting rope 5 passes through the rope groove 10. The three lifting ropes 5 support the base plate 1, which can effectively distribute the pressure and prevent the base plate 1 from deforming.

[0032] The top of the base plate 1 is provided with a frame-shaped limiting plate 2 to prevent the box-type substation from moving left or right or forward or backward during the lifting process. The top of the base plate 1 and near the left and right sides are provided with positioning components 4. The positioning components 4 are used to stabilize the relative position of the lifting rope 5 and ensure that the force on the entire lifting device is uniform.

[0033] The positioning component 4 includes two fixed columns 40 arranged symmetrically front and back to support the strip fixing plate 41. The tops of the two fixed columns 40 are connected to the strip fixing plate 41, providing a foundation for fixing the suspension rope 5. The outer side of the strip fixing plate 41 has three first arc-shaped grooves 410 arranged equidistantly front and back to guide the suspension rope 5 and ensure that the suspension rope 5 can be evenly stressed and have a stable direction.

[0034] It also includes a lifting plate 6 for connecting with lifting equipment. The lifting plate 6 is used to transfer the force of the lifting equipment to the lifting ropes 5 and the base plate 1. There are three connecting side rings 60 arranged equidistantly on the left and right sides of the lifting plate 6. The connecting side rings 60 are used to connect to the ends of the lifting ropes 5 respectively and to evenly distribute the force on each lifting rope 5 during the lifting process. The ends of the lifting ropes 5 pass through the first arc-shaped groove 410 and are connected to the corresponding connecting side rings 60. The three connecting side rings 60 on the left are connected to the left ends of the three lifting ropes 5 respectively, and the three connecting side rings 60 on the right are connected to the right ends of the three lifting ropes 5 respectively, thereby forming a stable lifting structure.

[0035] In this embodiment, the outer side of the frame-shaped limiting plate 2 is threaded with multiple clamping threaded rods 3, and the inner end of the clamping threaded rods 3 is rotatably connected with a circular pressure block 30. The circular pressure block 30 is located inside the frame-shaped limiting plate 2. By tightening the multiple clamping threaded rods 3, the circular pressure block 30 is pressed against the side of the box-type substation base, thereby fixing the position of the box-type substation and the base plate 1.

[0036] Specifically, a detachable strip movable plate 42 is provided on the outer side of the strip fixed plate 41. Three second arc-shaped grooves 420 are provided on the side of the strip movable plate 42 near the strip fixed plate 41. The lifting rope 5 is pressed between the second arc-shaped grooves 420 and the first arc-shaped grooves 410. The second arc-shaped grooves 420 and the first arc-shaped grooves 410 together form a clamping structure to press and fix the lifting rope 5, so that the position of the lifting rope 5 and the two positioning components 4 is relatively fixed, thereby fixing the relative position of the lifting rope 5 and the base plate 1, effectively preventing the base plate 1 from sliding left and right relative to the lifting rope 5 during the lifting process.

[0037] Furthermore, two mounting holes 421 are provided on the outer side of the strip movable plate 42, which are arranged symmetrically front to back. The mounting holes 421 are connected to fastening bolts 43. Through the fixing action of the fastening bolts 43, the strip movable plate 42 and the strip fixed plate 41 are firmly connected, and the fixing effect of the suspension rope 5 is further enhanced.

[0038] Furthermore, two threaded grooves 411 are provided on the outer side of the strip-shaped fixing plate 41, and the threaded ends of the two fastening bolts 43 are respectively threaded into the two threaded grooves 411, so that the fastening bolts 43 can be firmly installed on the strip-shaped fixing plate 41, thereby achieving reliable fixing of the strip-shaped movable plate 42.

[0039] Furthermore, a lifting ring 61 is provided at the center of the top of the lifting plate 6. The lifting ring 61 is used to directly connect with the lifting equipment to evenly transmit the pulling force of the lifting equipment to the entire device, ensuring that the lifting process is stable and safe.

[0040] Furthermore, anti-slip pads are provided at the four corners of the bottom of the base plate 1. The anti-slip pads are made of high-strength rubber and are used to increase the stability of the device on the construction site and prevent the base plate 1 from sliding or shifting due to wet or uneven ground.

[0041] In this embodiment, the auxiliary lifting device for the construction of the box-type substation is used. The box-type substation is placed stably on the top of the base plate 1 beforehand. By tightening the clamping threaded rod 3 on the outside of the frame-shaped limiting plate 2, the circular pressure block 30 connected to its inner end gradually presses against the side wall of the base of the box-type substation, thereby further fixing the position of the box and ensuring that the box-type substation and the base plate 1 remain stable during hoisting. Then, the pre-prepared lifting rope 5 is passed through the three rope grooves 10 at the bottom of the base plate 1, so that the lifting rope 5 is evenly distributed in the front and rear positions of the base plate 1, ensuring that the lifting rope 5 can firmly support the base plate 1, so as to evenly distribute the pressure during the hoisting process and avoid deformation of the base plate 1 due to excessive local stress.

[0042] Subsequently, the installation of the positioning component 4 is adjusted. The positioning component 4 consists of a fixed column 40 and a strip fixing plate 41. Its function is to fix the position of the lifting rope 5 and ensure that the lifting force is even. The two ends of the lifting rope 5 are respectively passed through the first arc groove 410 on the two strip fixing plates 41, and the lifting rope 5 is clamped through the second arc groove 420 on the strip movable plate 42. The strip movable plate 42 is firmly fixed to the strip fixing plate 41 using the mounting holes 421 and the fastening bolts 43, ensuring that the lifting rope 5 does not slip or loosen. In this way, the relative position of the lifting rope 5 and the base plate 1 remains fixed, thereby further ensuring the stability of the lifting process.

[0043] After completing the above steps, connect the two ends of the lifting rope 5 to the connecting side rings 60 on the left and right sides of the lifting plate 6 in sequence. The three connecting side rings 60 on the left are respectively connected to the left ends of the three lifting ropes 5, and the three connecting side rings 60 on the right are respectively connected to the right ends of the three lifting ropes 5, forming a lifting structure with uniform force. Finally, connect the lifting ring 61 at the top center of the lifting plate 6 to the lifting equipment. Through the pulling force of the lifting equipment, the lifting force is evenly distributed to multiple stress points of the entire device, ensuring that the lifting process is stable and safe.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
