Abstract
The utility model discloses a pin remover for a fan-shaped section, which pertains to the field of forming technology and is used for solving the problem of undamaged quick disassembly of an upper frame and a lower frame of the fan-shaped section of a continuous casting machine. The technical scheme is as follows: the pin remover comprises a drum, a round plate and a bolt which are coaxial to a pin to be removed, wherein the inner diameter of the drum is larger than the outer diameter of a hinge pin, the diameter of the round plate is larger than the outer diameter of the drum, a bolt hole matched with the bolt is arranged at the center of the round plate, the length of the bolt is longer than the sum of the length of the drum and the thickness of the round plate, the front end of the bolt penetrates the round plate and the drum in sequence, and the outer threads of the bolt are matched with the inner threads of a central threaded hole on the end surface of the hinge pin. As for the pin remover, the drum and the round plate are used as the support, the connecting hinge pin between the upper frame and the lower frame of the fan-shaped section of the continuous casting machine is pulled out by utilizing the tensile force of the bolt, and the hinge pin can not be damaged after being pulled out and can be reutilized, thus saving the overhauling cost of the fan-shaped section of the continuous casting machine. Simultaneously, the pin remover is convenient and efficient to operate, and greatly improves the overhauling efficiency.
Description
Technical field
The utility model relates to a kind of in order to extract the continuous casting machine fan-shaped segment device of framework connecting pin axle up and down, belongs to field shaping technique.
Background technology
Continuous casting machine fan-shaped segment up and down the connection between the framework be bearing pin by four Φ 110 with the realization that links together of upper frame hoist cylinder plug and underframe connecting rod, connected mode is as shown in Figure 1.Need decompose framework up and down during the maintenance of fan-shaped section off-line, this just need extract 4 bearing pins.Owing to there is not the special instrument of pulling pin at present, can only bearing pin be cut off with gas welding when decomposing up and down framework, so not only damaged bearing pin, cause the waste of material and the raising of the cost of overhaul, and it is longer to consume man-hour, 4 bearing pins removing a fan-shaped section probably need 6 hours, greatly reduce operating efficiency.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of fan-shaped section pin removal is provided, and to reduce the cost of overhaul, improves service work efficient.
The alleged problem of the utility model realizes with following technical proposals:
A kind of fan-shaped section pin removal, by forming with wait to pull pin axle coaxial cylinder, disk and a bolt, the internal diameter of described cylinder is greater than the external diameter of bearing pin, the diameter of described disk is greater than the external diameter of cylinder, its center is provided with the bolt hole that is complementary with bolt, shown in the length of bolt greater than drum length and disc thickness sum, the front end of bolt passes disk and cylinder successively, the internal thread of its external screw thread and pin roll end face screwed hole of centre is complementary.
Above-mentioned fan-shaped section pin removal, the card relative with cylinder of described disk are provided with a plurality of along the cylindrical wall inboard or the uniform locating piece in the outside.
The utility model is a support with cylinder and disk, utilizes the pulling force of bolt to extract the continuous casting machine fan-shaped segment connection bearing pin between the framework up and down, after extracting, can not destroyed bearing pin, but the secondary utilization, the cost of overhaul of having saved continuous casting machine fan-shaped segment.Simultaneously, this device is easy to operate, quick, has improved service work efficient greatly.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is a fan-shaped section framework connection diagram up and down;
Fig. 2 is a structural representation of the present utility model;
Fig. 3 is a using method schematic diagram of the present utility model.
Each label is among the figure: 1, underframe connecting rod; 2, upper frame hoist cylinder plug; 3, bearing pin; 4, cylinder; 5, disk; 6, bolt; 7, locating piece.
The specific embodiment
Referring to Fig. 2, the utility model is made up of cylinder 4, disk 5, bolt 6 three parts, and preparation method is as follows:
1, utilizes the cylinder of the long 200mm of thick steel pipe processing of Φ 170mm * 20mm;
2, utilize the disk of a Φ 200mm of 40mm steel plate processing, and the hole of opening Φ 45mm at the center;
3, get one of M42 * 300mm high-strength bolt.
Referring to Fig. 3, using method of the present utility model is as follows:
1, opens the screwed hole of M42 * 50mm at each bearing pin 3 center;
2, three parts with pin removal assemble, and bolt 6 threaded ends are screwed into Φ 42 screws on the bearing pin;
3, utilize BE56 or BE72 pneumatic impact wrench to beat M42 * 300mm high-strength bolt 6, utilize the bolt 6 and the reaction force of fan-shaped section oil cylinder plug 2 that bearing pin 3 is extracted.
Locating piece 7 on the disk 5 is used to limit the relative position of disk 5 and cylinder 4, makes the two maintenance coaxial.
The actual proof of using, when utilizing this pin removal to decompose up and down framework, each pin can both normally be extracted, and the time that every fan-shaped section is removed bearing pin only needs 2 hours.
