Description

Special hoisting tool for circuit breaker

technical field

The utility model relates to a special hoisting tool, in particular to a special hoisting tool for a circuit breaker.

Background technique

At present, the 500kV substation generally adopts a compact design, and the 35kV equipment area is close to the main transformer and adopts an open design, resulting in a narrow maintenance work space, and large hoisting equipment cannot be smoothly entered or deployed. In this working environment, once the 35kV switch is damaged and needs to be disassembled and replaced, there is no suitable lifting tool, which brings difficulties to the maintenance work. The manual hoist of the special hoisting tool of the existing circuit breaker cannot be protruded, and the steel pipe will touch the circuit breaker when the circuit breaker is hoisted, causing damage to the circuit breaker.

Utility model content

The purpose of this utility model is to provide a special hoisting tool for a circuit breaker, which can solve the above problems.

In order to achieve the above object, the utility model is achieved through the following technical solutions: a special hoisting tool for a circuit breaker, including a base, a fixing device and a hoist are installed on the base, a steel pipe is installed on the fixing device, the lower end of the steel pipe is hinged with the fixing device, and the steel pipe Install the fixed rod at the upper end, the straight line where the fixed rod is located is collinear with the straight line where the steel pipe is located, the boom is installed on one side of the fixed rod, and the diagonal tie rod is installed at the upper end of the boom, one end of the diagonal stay rod is connected with the fixed rod, and the other end of the diagonal stay rod is connected with the boom One end of the hoist is connected, the boom, the diagonal stay rod and the fixed rod form a triangle, one end of the boom is equipped with a rotating ring, the rotating ring is equipped with a lifting ring, and a manual hoist is installed on the lifting ring, and one end of the connecting rope of the winch is connected to the upper part of the steel pipe.

In order to further realize the purpose of the utility model, the following technical solutions can also be adopted: the fixing device includes two splints, the two splints clamp the base respectively, the two splints are connected by nuts and screw rods, and the splints on the upper side are installed The connecting piece is hinged with the steel pipe. The boom is perpendicular to the fixed rod.

The utility model has the advantages that: the hoist of the utility model can drive the steel pipe to rotate around the fixing device through the connecting rope. When the circuit breaker needs to be hoisted, the hoist loosens the connecting rope to make the steel pipe tilt to the side of the manual hoist, so that the manual hoist can come out , to avoid collision between the circuit breaker and the steel pipe to prevent damage to the circuit breaker. The manual hoist of the utility model can facilitate operators to lift the circuit breaker without using electric power. The triangle formed by the boom, the diagonal tie rod and the fixed rod of the utility model can improve the connection strength between the boom and the fixed rod, and avoid the damage of the boom during hoisting of the circuit breaker. The rotating ring of the utility model can facilitate the rotation of the manual hoist, so that the operator can control the manual hoist from different angles. The utility model also has the advantages of simple and compact structure, low manufacturing cost and easy use.

detailed description

The special hoisting tool for the circuit breaker, as shown in Figure 1, includes a base 9, a fixing device and a hoist 10 are installed on the base 9, a steel pipe 7 is installed on the fixing device, the lower end of the steel pipe 7 is hinged to the fixing device, and a fixing rod is installed on the upper end of the steel pipe 7 6. The straight line where the fixed rod 6 is located is collinear with the straight line where the steel pipe 7 is located. The boom 5 is installed on one side of the fixed rod 6, and the diagonal tie rod 4 is installed on the upper end of the boom 5. One end of the diagonal stay rod 4 is connected with the fixed rod 6. The diagonal stay rod 4 The other end of the boom 5 is connected to one end of the boom 5, the boom 5, the diagonal stay rod 4 and the fixed rod 6 form a triangle, one end of the boom 5 is installed with a rotating ring 3, and the ring 2 is installed on the rotating ring 3, and the manual hoist 1 is installed on the ring 2. , One end of the connecting rope 8 of the winch 10 is connected with the top of the steel pipe 7 .

The hoist 10 of the utility model can drive the steel pipe 7 to rotate around the fixing device through the connecting rope 8. When the circuit breaker needs to be hoisted, the hoist 10 loosens the connecting rope 8, so that the steel pipe 7 tilts to the side of the manual hoist 1, so that the manual hoist 1 out, to avoid collision between the circuit breaker and the steel pipe 7, to prevent damage to the circuit breaker. The manual hoist 1 of the utility model can facilitate operators to lift the circuit breaker without using electric power. The boom 5 of the utility model, the diagonal tie rod 4 and the fixed rod 6 form a triangle, which can improve the connection strength between the boom 5 and the fixed rod 6, and avoid damage to the boom 5 during the hoisting of the circuit breaker. The rotating ring 3 of the utility model can facilitate the rotation of the manual hoist 1, so that the operator can control the manual hoist 1 from different angles.

Described fixture comprises two splints 14, and two splints 14 clamp base 9 respectively, and two splints 14 are connected by nut 12 and screw mandrel 13, and the splint 14 that is positioned at upper side installs connector 15, and connector 15 and steel pipe 7 hinged. The two splints 14 of the utility model respectively clamp the base 9 to increase the connection strength between the fixing device and the base 9 .

The boom 5 is perpendicular to the fixed rod 6 . The boom 5 of the utility model is perpendicular to the fixed rod 6, and the force received by the boom 5 can be converted to the direction along the boom 5, thereby reducing the force on the boom 5 perpendicular to the direction of the boom 5.
