Abstract
The utility model relates to an engineering equipment foundation strengthening connector, in particular to a sleeve bolt capable of being used to repair a failure anchor bolt. The utility model solves the defects that butt welding strength is insufficient, adverse butt welding coaxiality is bad and binding welding needs big excavation volume of foundation in restoration failure of prior anchor bolts. The technical solution is that a sleeve bolt is characterized in that the shape is of a beer bottle shape, a bolt with a thread is arranged on the upper, the lower is an expanding diameter hollow sleeve, the circumference of the sleeve along the direction of a bus of the sleeve is opened with 3-5 through grooves for welding. The utility model is substantially used to repair the pre-buried and non replaceable anchor bolts of heavy-duty machineries such as smelting machinery, rolling machinery, and dynamic mechanical equipment.
Description
Technical field: the utility model relates to engineering equipment strengthening of foundation link, particularly a kind of sleeve bolt that can be used for repairing the inefficacy stone bolt.
Background technique: heavy machinery stone bolt working environment is more abominable, can run into high pressure water erosion, high temperature, electrochemical corrosion etc., frequently bear alternating shock load in addition, the screw thread burn into is threaded off, nut screwing clamping lost efficacy, and more serious also the stone bolt fatigue fracture can occur.Because the particularity that foundation construction and health require, so moving basis is abstained from the reparation of stone bolt very much.Some stone bolt can integral replacing after losing efficacy, as the stone bolt of T-shape head.And the stone bolt of most of built-in types, after bolt failure, because the root of bolt is buried in ground, at all can not integral replacing, can only take different repair modes at different failure modes: if 1 only be the screw thread stripped thread of slightly threading off, available threading die than small dimension hitch again on former screw rod basis.This method is simple, but prerequisite is the diameter of former screw rod enough allowances must be arranged, and the nominal diameter of the screw thread back stone bolt mechanical strength that attenuates has enough safety coefficient.2 if screw thread severe dropout stripped thread or screw rod fracture are generally adopted following method reparation: (1) butt welding.Be about to the former top of damaging the section screw rod and cut off, the more intact screw rod of butt welding the preceding paragraph.The method is because welding part stress is concentrated, and so strength deficiency, and coaxiality error is big after the butt welding is rare use.(2) binding weldering.Be about to the former top of damaging the section screw rod and cut off, use 2-3 root reinforcing bar (diameter and screw rod nominal diameter are approaching) that intact screw rod and lower margin screw rod are tied up weldering again.It is enough that this method is tied up weldering intensity, but length that must the strict guarantee reinforcing bar, promptly the fitness for purpose fusion length is a 5-6 nominal diameter doubly, and fusion length is a 2.5-3 times of nominal diameter on the promptly intact screw rod, and fusion length is a 2.5-3 times of nominal diameter on the former stone bolt.For satisfying fusion length, just mean the excavated volume on basis very big.
Summary of the invention: the utility model technical issues that need to address are: guaranteeing to repair under the prerequisite of bolt strength, reduce the foundation excavation amount as far as possible.The technical solution of the utility model is: sleeve bolt, it is characterized in that profile is the beer ampuliform, and top is screwed screw rod, and the bottom is the hollow sleeve of hole enlargement, and the sleeve circumference has 3-5 groove that is used to weld along the sleeve generatrix direction.The beneficial effects of the utility model are: because the former top of damaging the section screw rod is cut off, adopt the direct socket of sleeve bolt, guaranteed the coaxality of new bolt and former bolt root, the groove that the sleeve circumference has, for groove has been reserved in the welding of sleeve and original screw rod, so promptly guarantee the intensity of welding back bolt, can significantly reduce the excavated volume of ground again.

Fig. 2: be the utility model structural representation worm's eye view
Among the figure: 1-screw rod, 2-sleeve, 3-groove.
Embodiment: embodiment 1, with reference to accompanying drawing 1,2, sleeve bolt, profile is the beer ampuliform, top is screwed screw rod 1, the bottom is the hollow sleeve 2 of hole enlargement, and the sleeve circumference has 4 grooves that are used to weld 3 along the sleeve generatrix direction, and material adopts identical with stone bolt or close material.Heavy machinery as the built-in type of smelting machinery, rolling machinery and motive power machine equipment, non-exchange stone bolt if screw thread severe dropout stripped thread or screw rod fracture, the former top of damaging the section screw rod is cut off, adopt the direct socket of sleeve bolt, utilize groove 3 to be welded on the original stone bolt sleeve bolt.
Embodiment 2: less for the stone bolt diameter, the sleeve circumference has 3 grooves that are used to weld 3 along the sleeve generatrix direction, and all the other are identical with embodiment 1.
Embodiment 3: bigger for the stone bolt diameter, the sleeve circumference has 5 grooves that are used to weld 3 along the sleeve generatrix direction, and all the other are identical with embodiment 1.
Claims (1)
1, sleeve bolt is characterized in that, profile is the beer ampuliform, and top is screwed screw rod, and the bottom is the hollow sleeve of hole enlargement, and the sleeve circumference has 3-5 groove that is used to weld along the sleeve generatrix direction.
