[0002] The bushing lifting device for transformer parts is a device specially designed for safely and efficiently handling transformer bushings. Transformer bushings are an important component of the transformer, used to lead high voltage out of the transformer body and connect to the external circuit. Since bushings are usually large in size and weight, special lifting devices are required to ensure safety and stability during the lifting process.

[0032] like Figures 1 to 4 As shown, a lifting device for a bushing for transformer parts in one embodiment of the present invention includes a lifting device body 1 , a fixing mechanism 2 and a driving mechanism 3 .

[0033] Wherein, a sleeve body 101 is provided under the lifting device body 1.

[0034] like Figures 1 to 4 As shown, a fixing mechanism 2 is installed on the lower side of the lifting device body 1. The fixing mechanism 2 includes multiple pairs of connecting frames 201, which have a supporting function. The installation of the connecting frames 201 facilitates the movement of the fixed bin 202 and the corresponding mechanism.

[0035] In addition, a fixing bin 202 is fixedly installed on the connecting frame 201 , which has the benefit of support. The installation of the fixing bin 202 facilitates the installation of corresponding mechanisms in the fixing bin 202 , thereby facilitating the fixing of the sleeve body 101 .

[0036] In other words, the fixing chamber 202 is provided with a plurality of fixing blocks 203 , which can increase the friction between the fixing chamber 202 and the sleeve body 101 , while facilitating the fixing of the sleeve body 101 firmly.

[0037] Secondly, the fixing block 203 matches the sleeve body 101, and a first square groove matching the fixing block 203 is carved on the fixing chamber 202. The setting of the first square groove facilitates the installation of the spring 204 and provides space for the sliding of the fixing block 203.

[0038] In addition, a spring 204 is installed between the fixed block 203 and the fixed chamber 202, which has the function of buffering contraction, facilitating the squeezing effect of the fixed block 203, and at the same time facilitating the fixed block 203 to rebound to its original position.

[0039] In addition, a rack 205 is slidably installed in the fixed bin 202 on one side, and a first sliding groove matching the rack 205 is excavated in the fixed bin 202, which has the function of connecting a pair of fixed bins 202, so that the pair of fixed bins 202 are in a closed state, which can prevent the sleeve body 101 from falling.

[0040] like Figures 2 to 4 As shown, a rotating rod 206 is provided on one side of the fixed compartment 202, which has a supporting function, facilitates the installation of the gear 207, and has the benefit of driving the gear 207 to rotate.

[0041] In addition, a pair of gears 207 are installed on the rotating rod 206, and the gears 207 are engaged with the rack 205, which has the benefit of driving the rack 205 to slide, thereby making the sliding of the rack 205 more stable.

[0042] like Figures 2 to 4 As shown, a second square groove matching the gear 207 is bored on the fixed bin 202, and a first motor 208 is provided on one side of the fixed bin 202, the model of which is Y180M-2, which has a rotating function, facilitating the conversion of electrical energy into mechanical energy, thereby facilitating the rotation of the rotating rod 206.

[0043] like Figures 2 to 4 As shown, the first motor 208 is connected to the rotating rod 206, and a fixing frame 209 is fixedly installed on one side of the fixed compartment 202, which has the benefit of support. The support of the fixing frame 209 can make the rotating rod 206 more stably installed.

[0044] In other words, the rotating rod 206 is rotatably installed between the fixing frame 209, and a first bearing is installed between the rotating rod 206 and the fixing frame 209. The installation of the first bearing can not only ensure the stable installation of the rotating rod 206, but also enable the rotating rod 206 to smoothly realize the rotation function.

[0045] like Figures 3 and 4As shown, a driving mechanism 3 is installed on the lower side of the lifting device body 1. The driving mechanism 3 includes a pair of support plates 301. The support plates 301 are connected to the lifting device body 1. The connecting frame 201 is set through the support plates 301, which has the benefit of support and is convenient for installing corresponding mechanisms on the support plates 301 to drive the movement of the fixing mechanism 2.

[0046] like Figures 1 to 4 As shown, a second sliding groove matching the connecting frame 201 is carved on the support plate 301, and a pair of bidirectional threaded rods 302 are installed on the support plate 301, which has the advantage of rotation. The rotation of the bidirectional threaded rods 302 facilitates the movement of the connecting frame 201.

[0047] like Figures 1 to 4 As shown, a second bearing is installed between the bidirectional threaded rod 302 and the support plate 301, and limiting rods 303 are respectively installed on both sides of the bidirectional threaded rod 302, which has the benefit of limiting. Through the limiting of the limiting rod 303, the connecting frame 201 can achieve the benefit of linear movement according to the movement of the bidirectional threaded rod 302.

[0048] like Figures 1 to 4 As shown, the limiting rod 303 is fixedly installed on the support plate 301 , and the connecting frame 201 is slidably installed on the bidirectional threaded rod 302 and the limiting rod 303 .

[0049] like Figures 1 to 4 As shown, a second motor 304 is fixedly mounted on the support plate 301. The second motor 304 is connected to the bidirectional threaded rod 302. The model is Y180M-2 and has a rotating function, which is convenient for converting electrical energy into mechanical energy, thereby facilitating the rotation of the bidirectional threaded rod 302 on one side.

[0050] like Figures 1 to 4 As shown, a synchronous wheel 305 is installed on the bidirectional threaded rod 302, which has the function of receiving the rotational force of the bidirectional threaded rod 302 on one side and driving the bidirectional threaded rod 302 on the other side to rotate.

[0051] In addition, a synchronous belt 306 is installed between a pair of synchronous wheels 305, which has the advantage of receiving the rotational force of the synchronous wheel 305 on one side, thereby facilitating the transmission of the rotational force to the synchronous wheel 305 on the other side, driving the synchronous wheel 305 on the other side to also achieve rotation.

[0052] When in use, when the sleeve body 101 is fixed by the lifting device body 1, in order to prevent the sleeve body 101 from falling during the lifting process, the rotation of the second motor 304 can be used to drive the two-way threaded rod 302 to rotate when the sleeve body 101 is fixed, so that the two-way threaded rod 302 will drive the synchronous wheel 305 thereon to rotate, and the rotational force transmitted by the synchronous belt 306 will drive a pair of two-way threaded rods 302 to rotate synchronously, so that the rotation of the two-way threaded rod 302 and the limitation of the limit rod 303 will drive the connecting frame 201 to slide on the two-way threaded rod 302 and the limit rod 303, so that the two pairs of connecting frames 201 will drive the fixed bin 202 and the corresponding mechanism on the fixed bin 202 to approach inward at the same time, so that the movement of the fixed bin 202 will be The fixing block 203 is driven, and the fixing block 203 will first touch the sleeve body 101. When the fixing block 203 is subjected to the resistance of the sleeve body 101, the spring 204 will be squeezed, thereby increasing the friction between the fixing block 203 and the sleeve body 101, making the sleeve body 101 clamped more firmly. In order to strengthen the situation that the sleeve body 101 will fall, the rotation of the first motor 208 can be used to drive the rotating rod 206, and the rotating rod 206 can drive the rotation of the gear 207, so that the gear 207 can drive the rack 205 to slide out of the fixed warehouse 202, and it will move to the fixed warehouse 202 on the other side to match the first slide groove, which will make the sleeve body 101 encircled, thereby preventing the sleeve body 101 from tilting or sliding during lifting.
