Description

Alignment pin pulls away device
Technical field
The utility model relates to a kind of pin removal, and particularly a kind of alignment pin pulls away device, belongs to the hardware ﹠ tools field.
Background technology
Be applied to many large-scale rotating machinerys in power plant's power generation process; this equipment downtime maintenance interval is long; bearing is longer a duration of runs; the alignment pin of the fixed position such as bearing support is removed relatively difficulty during maintenance; artificial pin removal directly was connected with alignment pin originally; adopt artificial rotary nut to promote and pull away alignment pin; the time that this mode needs is longer; not easy to operate; pull away in the process because stressed concentrating causes that easily associated components damages; even " dead pin " phenomenon occurs, and the part specification that original pin removal is connected with alignment pin is single, can not adapt to the needs that pull away of different size alignment pin; these problems often cause maintenance process to prolong; consuming increases, and Homes Using TV reduces, and is unfavorable for normal carrying out smoothly of safeguarding and produce.
Summary of the invention
The utility model is for providing a kind of alignment pin to pull away device.
Alignment pin provided by the utility model pulls away device, what one Intermediate Gray spacing hole was set pulls away top power plate, be provided with in the spacing hole for the head that pulls away that is connected with alignment pin, the described head that pulls away comprises two sections, epimere directly inserts in the spacing hole, hypomere one end is fixedly connected with epimere, the other end is fixedly connected with alignment pin, the described power plate two ends, top that pull away are provided with top force mechanisms about the spacing hole symmetry, described top force mechanisms is: be fixedly installed two screwed pipes pulling away power plate two ends, top, two screwed pipes are symmetrical about spacing hole, screw rod is arranged on the top force mechanisms that forms two ends in the screwed pipe, described top force mechanisms is: two hydraulic means are set pulling away power plate two ends, top, pull away top power plate and be fixedly connected with the piston rod of hydraulic means.
The useful technique effect that alignment pin provided by the utility model pulls away device is: adopt group power plate two ends, power top to be symmetrical arranged the top force mechanisms, stress point is many, stressed even, dial that parts are difficult for damaging in the process, pull away head and be divided into two sections, epimere can be fixedly specification, plurality of specifications can be set in the lower end that is connected with alignment pin of hypomere, to satisfy the needs that pull away of different alignment pins, the top force mechanisms can be set to the manually-operated mechanism that the screw flight pipe matches, and also can be set to hydraulic means.This apparatus structure is simple, is easy to make, and pulls away process fast, can effectively improve plant maintenance and maintenance efficiency.
Description of drawings
Fig. 1 is the schematic diagram of a kind of embodiment of the utility model.
Fig. 2 is the schematic diagram of the another kind of embodiment of the utility model.
Fig. 3 is the schematic diagram that the utility model pulls away head.
The specific embodiment
In order to explain more fully enforcement of the present utility model, provide embodiment of the present utility model.These embodiments only are the elaborations to this device, do not limit scope of the present utility model.
Such as accompanying drawing 1, shown in Figure 2, alignment pin pulls away device, what one Intermediate Gray spacing hole 1 was set pulls away top power plate 2, be provided with in the spacing hole 1 for what be connected with alignment pin and pull away 3, the described head that pulls away comprises two sections, epimere directly inserts in the spacing hole 1, hypomere one end is fixedly connected with epimere, one end is fixedly connected with alignment pin 4, illustrated among Fig. 3 and pulled away an epimere 3-1, hypomere 3-2, the screw thread that 3-3 among hypomere 3-2 part can arrange different size is fixedly connected with the screw that adapts to alignment pin, the 3-2 section can be connected with the 3-1 section by screw thread, also can pass through other quick connected mode, described power plate 2 two ends, top that pull away are provided with top force mechanisms about spacing hole 1 symmetry, described top force mechanisms is: be fixedly installed two screwed pipes pulling away power plate two ends, top, 5-1 among Fig. 1, be respectively screwed pipe a shown in the 5-2, screwed pipe b, two screwed pipes are about spacing hole 1 symmetry, screw rod is arranged on the top force mechanisms that forms two ends in the screwed pipe, 6-1 shown in Fig. 1,6-1 is respectively screw rod a, screw rod b, described top force mechanisms is: two hydraulic means are set pulling away power plate two ends, top, pulling away plate is fixedly connected with the piston rod of hydraulic means, 7-1 among Fig. 2, be respectively little hydraulic jack a shown in the 7-2, little hydraulic jack b, the piston rod of little hydraulic jack with pull away top power plate and be fixedly connected with.The utility model is when work, at first select corresponding hypomere to pull away head according to the concrete specification of alignment pin and after alignment pin is fixedly connected with again be arranged on spacing hole in an epimere that pulls away be connected, in structure shown in Figure 1, rotate simultaneously screw rod to the power face of top, top power face is the stationary plane of alignment pin fixture, pull away top power plate 2 in the screw rod rotary course and be subjected to opposite force to drive alignment pins 4 and extract by pulling away 3, directly the little hydraulic jack of jacking makes and pulls away that top power version is stressed to be driven alignment pins 4 and extract by pulling away 3 in structure shown in Figure 2.The useful technique effect that alignment pin provided by the utility model pulls away device is: adopt group power plate two ends, power top to be symmetrical arranged the top force mechanisms, stress point is many, stressed even, dial that parts are difficult for damaging in the process, pull away head and be divided into two ends, the upper end can be fixedly specification, the lower end that is connected with alignment pin of hypomere can be set and do specification more, to satisfy the needs that pull away of different alignment pins, the top force mechanisms can be set to the manually-operated mechanism that the screw flight pipe matches, and also can be set to hydraulic means.This apparatus structure is simple, is easy to make, and pulls away process fast, can effectively improve plant maintenance and maintenance efficiency.
After describing embodiment of the present utility model in detail, the personage who is familiar with this technology can be well understood to, can carry out various variations and modification not breaking away under above-mentioned claim and the spirit, any simple modification, equivalent variations and modification that all foundations technical spirit of the present utility model is done above embodiment, the scope that all belongs to technical solutions of the utility model, and the utility model also is not subject to the embodiment that gives an actual example in the specification.
