Abstract

The utility model discloses a disassembling and assembling device for a large-scale cylinder shaft type radial positioning pin. The disassembling and assembling device comprises a U-shaped frame, two screw rods, a transverse beam, a jacking rod, a hydraulic jack and a hydraulic pump. The two top ends of the U-shaped frame and the two ends of the transverse beam are respectively provided with a through hole. The two screw rods penetrate through the through holes in the two top ends of the U-shaped frame and the through holes in the two ends of the transverse beam respectively. A fixing nut and a limiting nut are screwed at the two ends of each screw rod respectively. The hydraulic jack and the jacking rod are sequentially located between the transverse beam and the U-shaped frame and abut against the middle of the transverse beam. The hydraulic pump is connected with the hydraulic jack through a pipeline. According to the disassembling and assembling device for the large-scale cylinder shaft type radial positioning pin, the disassembling and assembling work of the large-scale cylinder shaft type radial positioning pin is conveniently carried out, the defect that the large-scale cylinder shaft type radial positioning pin is disassembled or assembled by being knocked by a traditional mallet is overcome, disassembling efficiency and assembling efficiency are improved, and potential safety hazards in the disassembling and assembling processes are avoided.

Description

The attaching/detaching apparatus of large cylindrical axle class radial location pin
Technical field
The utility model relates to a kind of attaching/detaching apparatus of large cylindrical axle class radial location pin.
Background technology
In plant equipment, by being located at cylinder axis class alignment pin radially, to connect the application of other parts quite extensive, and as the coiling machine of steel band rolling, coiling machine is rolled into coil of strip by milling train hot rolling steel band out.In coiling machine, alignment pin is installed on the head of reel rotating shaft, this alignment pin is plate latch structure, weight reaches 26.8 kilograms, by alignment pin, the movable sleeve of coiling machine and pull bar are linked into an integrated entity, by harmomegathus hydraulic cylinder, pull pull bar by pull bar, to pull movable sleeve again, movable sleeve makes reel reach harmomegathus along moving left and right of reel rotating shaft, has guaranteed the normal work of coiling machine.Because alignment pin and being connected of pull bar and movable sleeve adopt interference fit, in the disassembly process of alignment pin, mostly adopt sledgehammer to knock and carry out dismounting, this dismounting mode wastes time and energy, and operating efficiency is extremely low, and has the potential safety hazard of the certain person and equipment.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of attaching/detaching apparatus of large cylindrical axle class radial location pin, utilize the convenient dismounting operation of implementing large cylindrical axle class radial location pin of this device, overcome traditional sledgehammer and knocked the defect of carrying out dismounting, improve dismounting efficiency, avoided the potential safety hazard of disassembly process.
For solving the problems of the technologies described above, the attaching/detaching apparatus of the utility model large cylindrical axle class radial location pin comprises U-shaped frame, two screw rods, crossbeam, push rod, hydraulic jack and hydraulic pump, two tops of described U-shaped frame and described crossbeam two ends are respectively equipped with through hole, described two screw rods penetrate respectively the through hole on two tops of described U-shaped frame and the through hole at described crossbeam two ends, described two screw rod two ends are screwed with respectively hold-down nut and stop nut, described hydraulic jack and push rod are successively between described crossbeam and U-shaped frame and against crossbeam middle part, described hydraulic pump connects described hydraulic jack by pipeline.
Further, above-mentioned hydraulic pump is hydraulic hand-pump.
Because the attaching/detaching apparatus of the utility model large cylindrical axle class radial location pin has adopted technique scheme, be that this device comprises U-shaped frame, two screw rods, crossbeam, push rod, hydraulic jack and hydraulic pumps, two tops of U-shaped frame and crossbeam two ends are respectively equipped with through hole, two screw rods penetrate respectively the through hole on two tops of U-shaped frame and the through hole at crossbeam two ends, two screw rod two ends are screwed with respectively hold-down nut and stop nut, hydraulic jack and push rod are successively between crossbeam and U-shaped frame and against crossbeam middle part, and hydraulic pump connects hydraulic jack by pipeline.The convenient dismounting operation of implementing large cylindrical axle class radial location pin of this device, has overcome traditional sledgehammer and has knocked the defect of carrying out dismounting, has improved dismounting efficiency, has avoided the potential safety hazard of disassembly process.
Accompanying drawing explanation
Below in conjunction with drawings and embodiments, the utility model is described in further detail:
Fig. 1 is the attaching/detaching apparatus structural representation of the utility model large cylindrical axle class radial location pin;
Fig. 2 is the side view of Fig. 1;
Fig. 3 is the schematic diagram that adopts this device dismounting coiling machine alignment pin;
Fig. 4 adopts this device that the schematic diagram of coiling machine alignment pin is installed.
The specific embodiment
As depicted in figs. 1 and 2, the attaching/detaching apparatus of the utility model large cylindrical axle class radial location pin comprises U-shaped frame 1, two screw rods 2, crossbeam 3, push rod 5, hydraulic jack 4 and hydraulic pump 6, 1 two tops of described U-shaped frame and described crossbeam 3 two ends are respectively equipped with through hole, described two screw rods 2 penetrate respectively the through hole on 1 two tops of described U-shaped frame and the through hole at described crossbeam 3 two ends, described two screw rod 2 two ends are screwed with respectively hold-down nut 7 and stop nut 8, described hydraulic jack 4 and push rod 5 are successively between described crossbeam 3 and U-shaped frame 1 and against crossbeam 3 middle parts, described hydraulic pump 6 connects described hydraulic jack 4 by oil pipe 9.
Further, above-mentioned hydraulic pump 6 is hydraulic hand-pumps.Hydraulic hand-pump, without power supply, is convenient to the operation of production scene.
As shown in Figure 3, when the operation of coiling machine disassembling positioning pin, lifting U-shaped frame 1 is placed near reel rotating shaft 11 bottoms alignment pin 10, two screw rod 2 bottoms penetrated respectively in the through hole on 1 two tops of U-shaped frame and adopt hold-down nut to fix two screw rods 2, lifting cross beam 3 also penetrates respectively in the through hole at crossbeam 3 two ends two screw rod 2 tops, two screw rod 2 tops are screwed into stop nut 8, put push rod 5 and hydraulic jack 4 well, hydraulic jack 4 base abuts crossbeam 3 middle parts, push rod 5 front ends are against alignment pin 10, measuring crossbeam 3 to the distance on 1 two tops of U-shaped frame and adjusting stop nut 8 equates it, the oil pipe 9 of connecting fluid press pump 6 and hydraulic jack 4, primer fluid press pump 6 makes push rod 5 pushing tow alignment pins 10, until alignment pin 10 is ejected to pin-and-hole, complete the dismounting of alignment pin 10.As shown in Figure 4, when coiling machine alignment pin installation exercise, lifting U-shaped frame 1 is placed on the bottom of reel rotating shaft 11 pin-and-holes 10, assemble this attaching/detaching apparatus, placement positioning pin 10 alignment pin axis hole, then put hydraulic jack 4 connecting fluid press pump 6 well, push rod is between alignment pin 10 and hydraulic jack 4, measure crossbeam 3 to the distance on 1 two tops of U-shaped frame and it is equated, primer fluid press pump 6 makes push rod pushing tow alignment pin 10 enter the pin-and-hole of reel rotating shaft 11, completes the installation of alignment pin 10.
