[0004] The technical solution adopted by the present invention to solve the technical problem is: A transformer hoisting platform for 10kV transformer substation construction includes a bottom plate, a first curved pallet, a second curved pallet, an I-shaped frame and a U-shaped frame. There are two bottom plates, and a first curved pallet is arranged between the left sides of the two bottom plates, a second curved pallet is arranged on the left side of the first curved pallet, a first guide wheel is arranged on the top surface of the bottom plate, an I-shaped frame is arranged above the first guide wheel, a rear slide plate is arranged on the left side of the I-shaped frame, and U-shaped frames are arranged at both ends of the I-shaped frame.

[0005] The right end of the bottom plate is distributed in a slope shape, and the left end of the bottom plate is fixedly connected to the ground through a positioning pin.

[0006] The first arc-shaped clamping plate and the second arc-shaped clamping plate are two identical arc-shaped clamping plates and are symmetrically distributed on both sides of the tower pole. First screw rods are arranged at both ends of the second arc-shaped clamping plate. The first screw rods penetrate the first arc-shaped clamping plate and are fixed by matching nuts.

[0007] The end of the U-shaped frame passes through the I-shaped frame, and a matching nut is screwed on the end of the U-shaped frame.

[0008] A rear bracket is arranged in the middle of the left side of the I-beam frame, and a rear slide plate is fixedly connected to the outer side surface of the rear bracket. The left side surface of the rear slide plate is distributed in an arc-shaped groove shape, and a second guide wheel is arranged on the left side surface of the rear slide plate. A lifting lug is arranged on the top of the rear slide plate.

[0009] A first fixing member and a second fixing member are sequentially arranged above the base plate, and both the first fixing member and the second fixing member are composed of a positioning plate and a clamping strip, the positioning plate is arranged on the left side of the tower pole, and the clamping strip is arranged on the right side of the tower pole, and second screw rods are respectively arranged at both ends of the clamping strip, and the second screw rod passes through the connecting plate at the end of the positioning plate and is fixed by a matching nut so that the fixing member and the tower pole are clamped together.

[0010] A hand-cranked hoist is arranged on the right side of the first fixing member, and a guide wheel is arranged on the right side of the second fixing member. A pull rope runs through the guide wheel, and the right end of the pull rope passes through the handle of the hand-cranked hoist and is fixedly connected to the handle of the hand-cranked hoist.

[0011] The construction method of the transformer hoisting platform for the 10 kV transformer substation project construction comprises the following steps: S1. Place the bottom plate on one side of the bottom of the tower pole so that the inner wall of the first arc-shaped cardboard is in close contact with the outer wall on the right side of the tower pole, and then place the second arc-shaped cardboard on the left side of the tower pole so that the inner wall of the second arc-shaped cardboard is in close contact with the outer wall on the left side of the tower pole. At this time, the first screw at the right end of the second arc-shaped cardboard passes through the first arc-shaped cardboard, and a matching nut is screwed on the end of the first screw to fix the two arc-shaped cardboards and the bottom of the tower pole together; S2. Insert a positioning rod through the left end of the bottom plate to fix the positioning rod to the ground; S3. According to the installation position of the transformer, a first fixing member is arranged above the position, and a second fixing member is arranged above the first fixing member.

One worker holds the left end of the pull rope on the tower pole, and another worker pulls the other end of the pull rope on the ground. The worker on the ground pulls the pull rope repeatedly, and the worker on the tower pole cooperates to prevent the rope from falling. During the repeated pulling, the transformer and the I-beam frame move up along the tower pole; S7. After the transformer and the I-shaped frame are moved to the installation location, the staff will install the transformer. After the installation is completed, the U-shaped frame and the I-shaped frame can be removed using a hand hoist.

[0012] The positive beneficial effects of the present invention are: 1. The present invention places the transformer on an I-shaped frame and arranges a rear slide plate on the left side of the I-shaped frame, thereby avoiding friction and collision between the transformer and the tower pole during hoisting, and facilitating the rear slide plate to quickly move up along the tower pole. By arranging a second guide wheel on the outer side of the rear slide plate, the friction between the rear slide plate and the tower pole is reduced, which is conducive to the staff to quickly carry out hoisting construction.

[0013] 2. The present invention provides a first guide wheel on the bottom plate, which is beneficial for moving the transformer along the bottom plate to the hoisting position or adjusting the transformer on the bottom plate before hoisting. The staff no longer needs to use manual handling to make local adjustments, which reduces the burden on the staff, is easy to use, and is simple to operate.

[0014] 3. The present invention arranges a first arc-shaped clamping plate between two base plates, and arranges a second arc-shaped clamping plate on the left side of the arc-shaped clamping plate, so as to facilitate clamping and fixing the base plate and the tower pole together. By arranging a positioning rod at the left end of the base plate, the base plate can be fixed to the ground, thereby ensuring the stability of the transformer when it moves on the base plate.

[0015] 4. The present invention arranges a wire wheel above the hand-cranked hoist, and fixes the pull rope on the wire wheel with the crank handle of the hand-cranked hoist. Two workers only need to cooperate to pull the two ends of the pull rope to move the transformer upward, thereby improving work efficiency, saving time and labor, and being easy to promote.
