For some known technologies, those skilled in the art may also adopt other alternative methods for implementation; and the accompanying drawings are only for more specific description of the embodiments, and are not intended to specifically limit the utility model.

[0022] like Figure 1 - Figure 2 As shown, an embodiment of the utility model provides a safe lifting device for power equipment for power construction, including a base 1, which is a rectangular frame structure, a cross bar 2 is horizontally arranged at the middle position on the top of the base 1, a bracket 3 is fixedly connected to the top of the cross bar 2, and a roller 7 is rotatably connected to the middle position of the top of the bracket 3; a guide rail 6 is vertically arranged and two are provided, and the two guide rails 6 are arranged parallel to each other and on the same side of the bracket 3; a storage plate 8 is used for temporarily storing power equipment, and the back side of the storage plate 8 is slidably connected to the guide rail 6 through a slider 15; a winding roller 13 is fixedly connected to the top of the base 1 through a mounting plate, and a steel wire rope 14 is wound on the winding roller 13, one end of the steel wire rope 14 passes through the top of the roller 7 and is connected to the storage plate 8 through an ear plate 10, and the steel wire rope 14 is rollingly connected to the top area of ​​the roller 7; two positioning members 5 are provided, and are respectively fixedly connected to the two ends of the same side of the bracket 3 for contacting with the electric pole.

[0023] By setting a lifting bracket 3 composed of a base 1, a crossbar 2, a bracket 3, and a support rod 4, and cooperating with two positioning members 5 to abut against the electric poles, when in use, the lifting device is fixed between the two electric poles, and the transformer is temporarily installed on the storage plate 8, and the steel wire rope 14 is rolled up by rotating the winding roller 13 to achieve the lifting of the storage plate 8 and the transformer, wherein the positioning member 5 is abutted and supported by the electric poles, the transformer is always stably lifted in a straight line between the two electric poles during the lifting process, which is convenient for installation, and after the transformer is installed, the temporary installation of the transformer and the storage plate 8 can be directly released, and the lifting bracket 3 can be directly moved away, which is convenient to operate.

[0024] like Figure 1As shown, the bracket 3 includes two oblique rods inclined from bottom to top toward both sides, and a cross beam fixedly connected to the top of the two oblique rods, and the bottom of the oblique rod is fixedly connected to the top of the cross beam 2.

[0025] This arrangement is used to reduce the width of the base 1 so that it can pass through the middle of two utility poles for installing the transformer.

[0026] like Figure 1 As shown, it also includes a support rod 4, both ends of which are fixedly connected to the side walls of the inclined rods on the bracket 3 and the top of the base 1 for supporting the bracket 3. There are four support rods 4, which are respectively located on both sides of the two inclined rods.

[0027] This arrangement is used to support the bracket 3, thereby ensuring its structural stability and improving the safety of the transformer lifting operation.

[0028] like Figure 1 As shown, the storage plate 8 is an L-shaped plate structure, and two parallel sliding blocks 15 are provided on the back of the storage plate 8 to cooperate with the two guide rails 6 for sliding connection.

[0029] By providing two guide rails 6 and two sliders 15 in cooperation and sliding connection, the storage plate 8 can move linearly during the sliding process, ensuring that the bottom plate of the storage plate 8 for mounting the transformer will not tilt during the sliding process.

[0030] like Figure 1 As shown, the ear plate 10 is fixedly connected to the top center position of the back plate of the storage plate 8, and straps 9 are provided on both sides of the back plate of the storage plate 8 for hooping electrical equipment.

[0031] This arrangement further improves the firmness of the temporary installation of the transformer, preventing the transformer from slipping during the lifting process, causing it to fall and cause a safety accident.

[0032] like Figure 2 As shown, it also includes a motor 11, which is fixed on the top of the mounting plate. The motor 11 is connected to one end of the winding roller 13 through a gearbox 12, and is used to drive the winding roller 13 to rotate, wherein the output end of the motor 11 is connected to the input end of the gearbox 12. After being decelerated by the gearbox 12, the output end of the gearbox 12 is connected to one end of the winding roller 13.

[0033] By setting the motor 11 to provide lifting power and by setting the gearbox 12 to provide a transmission ratio for reducing the rotation speed, the output torque of the motor 11 is increased to provide stronger power.

[0034] like Figure 1 As shown, the positioning member 5 includes an extension rod fixedly connected to the bracket 3, and an arc-shaped plate fixed to an end of the extension rod away from the bracket 3, and the two arc-shaped plates face the same direction.

[0035] The technical solution provided by the utility model is that when it is necessary to lift the power equipment (i.e., the transformer), first, the storage plate 8 is located at the initial position at the bottom end of the device, and the transformer is installed on the bottom plate of the storage plate 8 by means of bolts or straps, and one side of the storage plate is close to the back plate, and the transformer is hooped by the strap 9. Subsequently, the side with the storage plate 8 is taken as the front end, and the base 1 is passed through the two electric poles and continuously pushed forward so that the two positioning members 5 are respectively abutted against the pole bodies of the electric poles on both sides to complete the fixation, and then the motor 11 is started, and the gearbox 12 is driven to drive the winding roller 13 to rotate the winding wire rope 14, and the storage plate 8 is driven to be lifted upward along the guide rail 6 under the guidance of the roller 7. After it is lifted to a preset height, the transformer is fixed between the two electric poles by the cross arm, and then the connection between the transformer and the storage plate 8 is disconnected, and the motor 11 is driven to make the storage plate 8 descend and reset, and finally the entire device is removed.

[0036] The present invention covers any substitution, modification, equivalent method and scheme made on the essence and scope of the present invention. In order to make the public have a thorough understanding of the present invention, specific details are described in detail in the above preferred embodiments of the present invention, and those skilled in the art can fully understand the present invention without the description of these details. In addition, in order to avoid unnecessary confusion about the essence of the present invention, well-known methods, processes, procedures, components and circuits are not described in detail.

[0037] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
