Abstract

The utility model discloses a fixed hollow driller. The utility model has the technical proposal that a supporter shaft is connected with a water collecting cover which is provided with a water exhausting hole through a connecting plate. The front end of the supporter shaft is connected with a sucking disc, the middle part of the supporter shaft is assembled with a supporter, and one end of the supporter is in screwed connection with a supporting rod. The sucking disc, the supporter shaft and the supporter are communicated with an air sucking hole. The back end of the supporter shaft is connected with a column, and a driller handle is sheathed on the column in sliding. The utility model has the advantages of the fixed hollow driller is fixed on the surface of the drilled object. The balance does not need to be handled by a person in drilling, the use is safe, the equipment is not damaged, the drilling quality is high, the splash of the cold water can be prevented, and the cleanness of the working face can be kept.

Description

Fixed hollow driller

The utility model belongs to a kind of hollow rig, particularly a kind ofly rig can be fixed on the fixed hollow rig that creeps on the drilled object.

Past holes on armored concrete, brick wall, cement pavement, all building stones of bituminous paving, mostly adopts equipment such as rock drill, electric hammer, and not only efficient is low, labour intensity is big, and is difficult to reach the requirement of construction quality.Provide a kind of portable hollow rig for the user in recent years, the problems referred to above have been solved, but the problem that exists is: it is bigger to grasp the balance difficulty by the operator, in case grasp unstable, fragile drill bit, flexible axle, even damage motor, drill bit needs water to cool off during in addition owing to boring, cold water splashes everywhere when therefore holing, and causes the pollution to metope.

The purpose of this utility model provides a kind of hollow rig that is fixed on the drilled object, does not choose and grasps balance, and is safe in utilization, damage equipment does not creep into the quality height, alleviates labor intensity of operating personnel, and avoid cooling water to splash everywhere, keep creeping into the working face cleaning.

The technical solution of the utility model is as follows: the catchment covers of support shaft and band osculum connects by connecting plate, the front end of support shaft has the screwed hole that is screwed bolt and connects sucker, the middle part assembling support of support shaft, the threaded one end of support connects pole, sucker, support shaft and support have suction hole to communicate, and unidirectional valve is arranged on the support, and the support shaft rear end is screwed column by the attaching nut, on the machine handle leghole is arranged, slip cap is contained on the column.

Operation principle: before the boring, catchment covers and sucker are placed on the drilled object surface, can adopt expansion bolt that support shaft is fixed on the boring surface, also can adopt the vacuum suction of sucker, promptly find time, make sucker be adsorbed in the boring body surface tightly, and turn pole by the unidirectional valve on the support, make its balance support, the osculum of the catchment covers glue pipe that runs in.Rig is contained on the column, when creeping into rig along column forward, the cooling water that hollow boring bit is discharged is discharged from the osculum of catchment covers.Rig also can use separately as required.

The utility model has the advantages that: rig can be fixed on the drilled object surface, not choose in creeping into and grasp balance, safe and reliable, damage equipment does not creep into the quality height, can alleviate labor intensity of operating personnel, and can prevent that cooling water from splashing, keep creeping into the working face cleaning.When not needing fixedly, can be used as portable portable rig and use.

Below in conjunction with accompanying drawing the utility model embodiment is described further.

Fig. 1 is the utility model structural representation.

See Fig. 1, concrete structure of the present utility model is as follows: the discharge outlet 3 that communicates with sebific duct is arranged on the catchment covers 1, and the base of catchment covers 1 is stained with seal gasket 4, is welded to connect plate 2 on the catchment covers 1, and an end of connecting plate 2 has circle hole sleeve to be contained on the support shaft 9; The front end of support shaft 9 has round platform, and sucker 10 is sleeved on the support shaft 9, and by nut 11 that sucker 10 and connecting plate 2 is fixing, the front end of sucker 10 is stained with seal gasket 5.Support 12 is sleeved on the middle part of support shaft 9, and is fixing by attaching nut 19.Suction hole 14 is arranged on the support 12, and unidirectional valve 15 is housed, its external asepwirator pump.The connecting hole internal diameter of support 12 has ring-shaped ventilation road 17 and suction hole 14 to communicate, and O-ring seal 18 is equipped with in the front and back in ring-shaped ventilation road 17; The front end of support shaft 9 has with expansion bolt 8 and is connected with screwed hole, and has passage 6 radially that the screwed hole and sucker 10 inner chambers of support shaft 9 are communicated with, and also has axial hole 7 and radial hole 16 to be communicated with the ring-shaped ventilation road 17 of supports 12 on the support shaft 9, constitutes air intake passage.The threaded one end of support 12 is screwed pole 13, and column 20 screw threads are screwedly mounted on the attaching nut 19.On the machine handle 21 leghole is arranged, during use machine handle 21 is enclosed within on the column 20, and can be in last slip.

Claims

1, a kind of fixed hollow rig, comprise hand-held drill machine handle, it is characterized in that: the catchment covers of support shaft and band osculum connects by connecting plate, and the front end of support shaft has the screwed hole that is screwed bolt and connects sucker, the middle part assembling support of support shaft, the threaded one end of support connects pole, sucker, support shaft and support have suction hole to communicate, and unidirectional valve is arranged on the support, and the support shaft rear end is screwed column by the attaching nut, on the machine handle leghole is arranged, slip cap is contained on the column.
