Embodiment
Hereinafter will and combine embodiment to specify the present invention with reference to accompanying drawing.Need to prove that under the situation of not conflicting, embodiment and the characteristic among the embodiment among the application can make up each other.
Structural body in the various embodiments of the present invention refers to be used in the piling machinery be provided with the structure that supplies the mounting hole that flexible pipe passes.
Extremely shown in Figure 3 like Fig. 1; According to the first embodiment of the present invention; A kind of flexible pipe safeguard structure comprises structural body 10; Structural body 10 is provided with the mounting hole 11 that supplies flexible pipe to pass, and also comprises the rigidity circular arc safeguard structure 12 towards the center of mounting hole 11 on the structural body 10, and flexible pipe is arranged in the circular arc safeguard structure 12 formed receiving cavities.Rigidity circular arc safeguard structure 12 is meant that the hardness of the part that this circular arc safeguard structure 12 contacts with flexible pipe should be greater than the hardness of flexible pipe, and this circular arc safeguard structure 12 can not move with the motion of flexible pipe.Preferably, this flexible pipe safeguard structure is the hydraulic hose safeguard structure.
Circular arc safeguard structure 12 mainly is arranged between the seamed edge and flexible pipe of mounting hole 11 periphery in the structural body 10, prevent flexible pipe directly and the sharp edges edge joint touch, flexible pipe is caused the breakage of grinding away.The circular arc safeguard structure 12 of rigidity can prevent in use, and it is loosening that the flexible pipe action causes circular arc safeguard structure 12 to take place, and causes circular arc safeguard structure 12 to depart from excessive or breaks away from mounting hole 11 and lose the protective action to flexible pipe, guarantees protection effect.Circular arc safeguard structure 12 can directly process through the mounting hole circumferential side wall to structural body 10; Also can form through the sheathed auxiliary rigid protection spare 20 of mounting hole 11 internal fixation in structural body 10, the safeguard structure that is formed by inventive embodiment is easy to process, and cost is lower; Adaptability is good; Structural stability can play protective action preferably, and flexible pipe is formed better protection.
In a unshowned embodiment, when circular arc safeguard structure 12 directly processed through the mounting hole circumferential side wall to structural body 10, circular arc safeguard structure 12 was formed on the mounting hole circumferential side wall of structural body 10.Flexible pipe passes mounting hole 11 and is provided with.Because there is not seamed edge in the mounting hole periphery, and be towards the anti-mask of the protruding arc of flexible pipe, therefore, flexible pipe in time with respect to structural body 10 motions, can not cause the breakage of grinding away yet when work, has prolonged working life effectively, has protected flexible pipe.Because only need process the seamed edge of structural body 10 according to the structure of the mounting hole 11 of structural body 10, so adaptability is strong, can satisfy the designing requirement of various structural body 10, simple in structure, easy to operate, cost is lower.
In the present embodiment; Mounting hole 11 internal fixation of structural body 10 are arranged with rigid protection spare 20; This rigid protection spare 20 is annular round steel, is connected for welding or bolt between annular round steel and the structural body 10, and circular arc safeguard structure 12 is formed on the inner ring surface of annular round steel.The annular round steel can pass through a round steel one bending and molding, also can be spliced through the multistage round steel.Drawing materials conveniently of round steel need not processing basically, as long as select suitable round steel to carry out bending at any time according to the size of mounting hole 11, and is fixedly installed in the mounting hole 11, just can form effective protection to flexible pipe easily.The annular round steel directly is welded on the structural body 10, and is very firm, can the dislocation that come off because of the strenuous vibration in when work, and protection stability height.The processing of annular round steel is simple, and cost is very low, and is simple in structure, and protection effect is good, and in the Workshop Production process, also the neglected loading phenomenon can not occur.
In conjunction with referring to Fig. 4 and shown in Figure 5; According to a second embodiment of the present invention; Itself and first embodiment's structure is basic identical, and difference is, in the present embodiment; Rigid protection spare 20 is annular steel bushing, and this annular steel bushing comprises outer side wall that is complementary with the mounting hole circumferential side wall of structural body 10 and the stop lug 21 that matches with the sidewall of structural body 10.The inner circle wall of annular steel bushing comprises in the arc transition section of both sides and is connected the section of facing directly between the arc transition section of both sides that both sides arc transition section and the centre section of facing directly have formed circular arc safeguard structure 12 jointly.Because connect through arc transition between the inner circle wall of annular steel bushing and the two side, therefore, flexible pipe is positioned at the inner circle wall of annular steel bushing, can not cause the breakage of grinding away, and has protected flexible pipe effectively.Stop lug 21 is sticked on the sidewall of structural body 10, not only can form the axially locating to structural body 10, but also fixed connection structures such as bolt hole can be set through stop lug 21, and is more convenient to operate.In addition, annular steel bushing can be installed on the structural body 10 after the use needs are satisfied in machine shaping, so manufacturing procedure is simpler, and is more convenient to operate.
In conjunction with referring to Fig. 6 and shown in Figure 7; A third embodiment in accordance with the invention; The flexible pipe safeguard structure comprises two awl springs 30 of structural body 10 and the both sides that are fixedly installed on structural body 10; Two awl springs 30 oppositely are provided with, and end is fixedly connected on the structural body 10 greatly, and circular arc safeguard structure 12 is the inner ring surface of awl spring 30.Flexible pipe directly passes in the middle of awl spring 30; Awl spring 30 has certain rigidity and elasticity, and inside during play, awl spring 30 can be offset the play of flexible pipe to flexible pipe in any direction; Flexible pipe is not contacted with the seamed edge of structural body 10, thereby play the effect of effective protection flexible pipe.
Embodiment according to a further aspect in the invention, a kind of rotary drilling rig comprises the flexible pipe safeguard structure, this flexible pipe safeguard structure is above-mentioned flexible pipe safeguard structure.
Embodiment in accordance with a further aspect of the present invention, a kind of piling machinery comprises the flexible pipe safeguard structure, this flexible pipe safeguard structure is above-mentioned flexible pipe safeguard structure.
From above description; Can find out; The above embodiments of the present invention have realized following technique effect: the flexible pipe safeguard structure comprises structural body, and structural body is provided with the mounting hole that supplies flexible pipe to pass, and it is characterized in that; Comprise on the structural body that flexible pipe is arranged in the formed receiving cavity of circular arc safeguard structure towards the rigidity circular arc safeguard structure at the center of mounting hole.Flexible pipe can directly contacting with the circular arc safeguard structure of rigidity in the process of work, and can be not directly with structural body on seamed edge contact, so structural body can not cause the damaging problem of grinding away to flexible pipe, effectively protected flexible pipe.
The above is merely the preferred embodiments of the present invention, is not limited to the present invention, and for a person skilled in the art, the present invention can have various changes and variation.All within spirit of the present invention and principle, any modification of being done, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
