Description

Technical Field

[0001] The utility model relates to the technical field of power equipment installation, in particular to a lifting transformer installation and fixing device. Background Art

[0002] A transformer is an electrical device that uses the principle of electromagnetic induction to change the size of AC voltage. Specifically, the transformer mainly consists of a primary coil, a secondary coil and an iron core (magnetic core). When an AC current flows through the primary coil, an AC magnetic flux is generated in the iron core (or magnetic core), which induces a voltage (or current) in the secondary coil. The main functions of a transformer include: voltage conversion, current conversion, impedance conversion, isolation, and voltage stabilization (for magnetic saturation transformers). According to the purpose of use, transformers can be divided into power transformers and special transformers. Among them, power transformers are mainly used in power transmission and distribution systems to increase or decrease voltage; while special transformers may be used in various specific electrical or electronic equipment to achieve specific electrical functions. In general, transformers are an indispensable and important component in modern power systems and various electrical equipment. They play a vital role in the transmission, distribution and use of electrical energy.

[0003] At present, during the installation of the transformer, it is necessary to first fix the mounting frame between two poles, then lift the transformer to the designated position with the help of lifting equipment, and then fix it with bolts and other fasteners. This method is not only complicated to operate, time-consuming and labor-intensive, but also has certain safety hazards. Therefore, it is particularly important to develop a device that can automatically lift and firmly fix the transformer. Utility Model Content

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] 1. The utility model realizes the lifting and fixing of the transformer through the built-in lifting components, which greatly simplifies the installation steps.

DETAILED DESCRIPTION

[0025] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Example:

[0027] like Figures 1 to 5As shown, a lifting transformer installation and fixing device comprises a fixing frame 4, which is clamped between two groups of electric poles 1, and the fixing frame 4 is fixedly connected by a connecting frame 17 inside. A transformer 3 is fixedly installed on the fixing frame 4 by bolts, and suspension rods 18 are welded and fixed on the left and right sides of the fixing frame 4. A cross beam plate 2 is arranged at intervals on the upper side of the fixing frame 4, and a reducer 7 is fixedly installed on the upper side of the cross beam plate 2. The output end of the reducer 7 is equipped with a driving motor 10, and a reel 5 is arranged on the cross beam plate 2. The input end of the reel 5 is fixedly connected to the reducer 7 through a driving shaft 6. A lifting steel cable 8 is wound on the reel 5, and one end of the lifting steel cable 8 passes through a movable pulley 9 and is fixedly connected to the bottom surface of the cross beam plate 2. This design solves the problem that during the installation of the transformer 3, the mounting frame needs to be fixedly installed between the two electric poles 1 first, and then the transformer 3 is lifted to a specified position by means of a lifting device, and then fixed by fasteners such as bolts. This method is not only complicated to operate, time-consuming and labor-intensive, but also has certain safety hazards.

[0028] Internal snap rings b16 are fixedly arranged on both sides of the fixing frame 4 near both ends, and the outer side of the internal snap rings b16 is fixedly connected with the outer snap rings b15 by bolts, and the internal snap rings b16 cooperate with the outer snap rings b15 to fix the fixing frame 4 on the electric pole 1. When the internal snap rings b16 and the outer snap rings b15 are tightly matched and fixed on the electric pole 1, they jointly bear the weight of the fixing frame 4 and the transformer 3 thereon, ensuring the stability of the entire device, effectively preventing the fixing frame 4 from sliding or falling off on the electric pole 1, and providing a strong guarantee for the safe operation of the transformer 3.

[0029] The left and right ends of the cross beam 2 are welded with inner snap rings a12, and the outer side of the inner snap ring a12 is fixedly connected with an outer snap ring a11 by bolts, and the cross beam 2 is fixedly connected to the electric pole 1 through the outer snap ring a11 and the inner snap ring a12. The outer snap ring a11 and the inner snap ring a12 can form a clamping structure for the electric pole 1, and the friction and clamping force between the outer snap ring a11 and the electric pole 1 can be used to firmly fix the cross beam 2 on the electric pole 1, thereby ensuring the stability of the cross beam 2.

[0030] The reel 5, the hoisting cable 8 and the movable pulley 9 constitute a hoisting assembly. There are two groups of hoisting assemblies, which are symmetrically arranged on the left and right sides of the crossbeam plate 2. The reel 5 is responsible for winding and releasing the hoisting cable 8, thereby controlling the lifting height of the transformer 3. As a bridge connecting the reel 5 and the transformer 3, the hoisting cable 8 bears the weight of the transformer 3 and transfers it to the reel 5. The movable pulley 9 plays the role of changing the direction of the hoisting cable 8, making the hoisting process smoother, while reducing the force required for hoisting and improving the hoisting effect. This design uses two groups of hoisting assemblies to simultaneously apply force to both sides of the fixed frame 4, ensuring the balance of the transformer 3 during the lifting process, ensuring the smooth lifting and lowering of the transformer 3, avoiding accidents caused by the deflection of the transformer 3, and enhancing the safety of installation.

[0031] A self-locking hook 14 is fixedly connected to the lower side of the movable pulley 9. The self-locking hook 14 is used to connect the movable pulley 9 to the suspension rod 18, and then the transformer 3 is lifted by the lifting cable 8. The self-locking hook 14 is convenient for connecting the lifting cable 8 to the suspension rod 18 on the fixed frame 4, thereby improving the convenience of operation.

[0032] A through slot 13 is provided inside the cross beam 2, and the position of the through slot 13 corresponds to the position of the reel 5, and the hoisting steel cable 8 passes through the through slot 13. The main function of the through slot 13 is to provide a passage for the hoisting steel cable 8 to pass through the cross beam 2, so that the hoisting steel cable 8 can extend from the reel 5 to the movable pulley 9. The hoisting steel cable 8 can be guided through the through slot 13, which can prevent the hoisting steel cable 8 from contacting the cross beam 2, reduce friction, and improve the hoisting effect.

[0033] Two sets of limit baffles 19 are fixed on the annular surface of the boom 18, and the diameter of the limit baffles 19 is larger than the diameter of the boom 18. By fixing the two sets of limit baffles 19, the movement range of the boom 18 on the annular surface can be accurately limited, which plays a role in limiting the self-locking hook 14 and preventing the self-locking hook 14 from sliding and deflecting on the boom 18, thereby helping to ensure the safety and reliability of the lifting operation.

[0034] A plurality of right-angled support pads 20 are fixedly arranged at the bottom of the fixing frame 4, and the bottom surface height of the support pads 20 is lower than the bottom surface height of the outer snap ring b15 and the inner snap ring b16. The right-angled support pads 20 can provide a stable support surface, increase the contact area between the fixing frame 4 and the ground or the installation foundation, thereby improving the support stability of the entire structure. At the same time, before the transformer 3 is hoisted, since the support pads 20 are in direct contact with the ground, the friction and collision between the outer snap ring b15 and the inner snap ring b16 and the ground can be reduced, thereby protecting these structural parts from damage.

[0035] The working principle of the lifting transformer installation and fixing device is as follows: first, the crossbeam plate 2 is fixedly connected to the electric pole 1 through the outer snap ring a11 and the inner snap ring a12 to form a clamping structure, and the crossbeam plate 2 is firmly fixed to the electric pole 1 by friction and clamping force. Then the fixing frame 4 is placed between the two groups of electric poles 1, the inner snap ring b16 is located on the inner side of the electric pole 1, and the fixing frame 4 is placed on the ground through the support pad 20. Then the transformer 3 is fixedly installed on the fixing frame 4 by bolts, and then the self-locking hook is connected to the suspension rod 18 inside the fixing frame 4. Start the drive motor 10, drive the reel 5 to rotate through the reducer 7, and the reel 5 starts to wind the hoisting steel cable 8. When the hoisting steel cable 8 is wound, the transformer 3 is smoothly lifted up to the specified position through the mechanical advantage generated by the movable pulley 9. After the transformer 3 reaches the target height, the drive motor 10 is turned off, and the hoisting steel cable 8 stops moving. Subsequently, the operator can fix the outer snap ring b15 with the inner snap ring through bolts. The inner clamping ring b16 and the outer clamping ring b15 cooperate closely to jointly bear the weight of the fixing frame 4 and the transformer 3 thereon, thereby ensuring stability and achieving the installation of the transformer 3.

[0036] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not limitations on the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made on the basis of the above description. It is impossible to list all the implementation methods here. All obvious changes or modifications derived from the technical solution of the present invention are still within the protection scope of the present invention.
