Abstract
The utility model relates to a kind of bolt disassembling tool, i.e. bolt tractor.It comprises support nut dish, and support nut dish connects three carrying bolts, and connection socket body in the middle of three carrying bolts, leading screw is connected with socket body through support nut dish, and leading screw outer end is with swing handle.This apparatus structure is simple, safe and reliable.Easy to operate, to alleviate operating personnel labour intensity, improves efficiency of construction.There is mobility, be applicable to any place and use.
Description
technical field
The utility model relates to a kind of bolt disassembling tool, i.e. bolt tractor.
Background technology
In the prior art, dam has bypass damper, water inlet plain batton door, arc door, and water inlet plain batton door has 35 fans, at least carries out 4 fan Jeakage through Sluice Sealants every year and more changes jobs.Water seal is sealed gate and aperture water leakage.Pressing plate water seal base plate, in the middle of bypass damper base plate and pressing plate, is serially connected with bolt, is fixed on gate faces plate framework by water seal.One fan brake door bolt needs 400 (water seal of P type, blade type water seal, adjusting pads) altogether, and when water seal is changed, disassembling bolts is very inconvenient.
Water inlet plain batton door, arc door bolt are dormant bolts, block bolt head during dismounting with pipe wrench, rotate with strength to pull out outward.Frequent slippage is unloaded to get off, and wastes time and energy, and adds intensity of workers.Grasp with hand hammer hammering and forbidden to be easy to hurt sb.'s feelings.
Utility model content
The purpose of this utility model provides a kind of bolt tractor for above-mentioned deficiency, has easy to use, laborsaving, the feature that efficiency is high.
Technical solution of the present utility model is: bolt tractor, comprises support nut dish, and support nut dish connects three carrying bolts, and connection socket body in the middle of three carrying bolts, leading screw is connected with socket body through support nut dish, and leading screw outer end is with swing handle.Described socket body bottom is tubulose, and side has gap, the interior platform with overlap joint bolt head.
The utility model has the advantages that: 1, this apparatus structure is simple, safe and reliable.2, easy to operate, the labour intensity that alleviates operating personnel, improves efficiency of construction.3, there is mobility, be applicable to any place and use.
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail.
Accompanying drawing explanation
Fig. 1 is the utility model structure diagram.
Detailed description of the invention
See Fig. 1, parts title is as follows: support nut dish 1, carrying bolt 2, socket body 3, leading screw 4, swing handle 5, platform 6, gap 7, socket plane 8.
See Fig. 1, bolt tractor comprises support nut dish 1, and support nut dish 1 connects three carrying bolts 2, three carrying bolt 2 middle connection socket body 3(and moves up and down under leading screw 4 drives), leading screw 4 is connected with socket body 3 through support nut dish 1, and leading screw 4 outer end is with swing handle 5.Socket body 3 moves up and down with middle leading screw 4.Socket body 3 bottom is tubulose, and side has gap 7(semicircle or not a half round gap), for allowing into bolt head to be pulled out, the interior platform 6 with overlap joint bolt head, the bolt head bottom surface to be pulled out allowed rides on platform 6, puies forward socket body 3, extract bolt then.Each carrying bolt 2 part can have spanner socket plane 8, for fastening bolt.See Fig. 1, carrying bolt 2 is circumferentially arrange three, shows two in figure.
During use, bolt tractor is placed on and wants draw bolt place (pressing plate at the bolt head back side to be pulled out is pounded usually, and space is exposed at the bolt head back side).Socket aligns the horizontal insertion of bolt tail (inserting as forklift pawl), and then turning handle, utilizes screw thread rotation principle.Its bolt is made to be pulled out pressing plate, water seal, base plate gradually.Carry out next bolt traction by that analogy.
