Method, it is inaccurate and lead to that demolition effect is undesirable and out break is serious to be easy to appear bore position, angle, in addition,
Also cause the labor intensity of construction personnel larger.
Retrieval through the prior art does not retrieve technical solution relevant to this patent.
Utility model content
The purpose of the utility model is to overcome in place of the deficiencies in the prior art, provide a kind of on air rock drill
Drilling rod auxiliary locator, the auxiliary locator is low in cost, and structure is simple, light, and hand steered drilling rod worker can be made easily to make
Industry, boring positioning are accurate.
The utility model solves its technical problem and adopts the following technical solutions to achieve:
A kind of drilling rod auxiliary locator on air rock drill, it is characterised in that: match including that can be installed with drilling rod
The tubular support portion of conjunction and the vertical upright part that is fixedly connected is formed with tubular support portion constitute；
The tubular support portion includes support tube body, installation gap is formed on support tube body, in support tube sheet
The internal upper two sides in installation gap of cavity wall are along the circumferential direction equipped with multiple universal ball bearings, and multiple universal ball bearings surround
Intracavity space be drilling rod penetrate chamber；
The upright part uses Telescopic rod structure comprising telescopic rod main part and is fixed on telescopic rod main part
The top fork of lower end point.
And, the telescopic rod main part is connected and composed by inner and outer tubes suit, and inner and outer tubes pass through along diameter
The screw that presses closer being arranged to direction makes two pipes be axially formed limit connection.
And, said inner tube and outer tube are all made of seamless steel pipe structure.
And, reinforcing support plate is welded between the upper end of inner tube and the outside of support tube body.
And, the support tube body is made by opening notch processed on seamless steel pipe.
The advantages and positive effects of the utility model are as follows:
The utility model ensure that by the drilling rod auxiliary locator being made of tubular support portion and upright part
During bore operation, drilling rod realizes the auxiliary positioning of drilling rod by the stable spatial position for being supported in setting, has following
The advantages of several aspects；
1. structure is simple, low in cost, it is easy assembling, use is light.
2. the characteristics of utilizing universal ball bearing, hinders without friction in boring procedure, energy loss is few.
3. hand steered more time saving and energy saving than artificial, boring positioning is accurate, and demolition effect is good.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing and by specific embodiment, and following embodiment is only retouched
The property stated, it is not restrictive, protection scope of this utility model cannot be limited by this.
A kind of drilling rod auxiliary locator on air rock drill, referring to Figure 1, including 1 He of tubular support portion
Upright part 3, upright part are in a vertical connection by welding or other fixed form shapes with tubular support portion.Tubular support portion
The effect divided is: installing cooperation with drilling rod formation, constrains drilling rod, to guarantee during bore operation, drilling rod is not in
Beat.The effect of upright part is: ground or rack are withstood in its underpart, and tubular support portion is supported in the space bit of setting
It sets, guarantees going on smoothly for bore operation.
The tubular support portion includes support tube body 1-1, is formed with installation gap 1-1-1 on support tube body,
Two sides on support tube chamber body wall positioned at installation gap are along the circumferential direction equipped with multiple universal ball bearing 1-2, Duo Gewan
The intracavity space surrounded to ball bearing is that drilling rod penetrates chamber 1-3.When in use, drilling rod is penetrated into drilling rod and penetrates chamber, drilling rod
It penetrates between chamber and drilling rod and needs to reserve fit clearance appropriate, on the one hand to guarantee that smoothly penetrating for drilling rod is pierced by, another party
Face will also guarantee the accuracy of positioning, for example, YT28 drill steel outer diameter 26mm, the width of installation gap is 40mm, and drilling rod penetrates chamber
Diameter is 32mm, has both been able to satisfy smoothly penetrating for drilling rod and has been pierced by, drilling accuracy also can guarantee.
The upright part uses Telescopic rod structure comprising telescopic rod main part and is fixed on telescopic rod main part
The top fork of lower end divides 3-3, and top fork point pitches structure using more stabilizer blade tops described in attached drawing.Upright bar uses Telescopic rod structure,
Advantage is: in certain size range, can adjust the length of upright part, to meet apart from ground or the different height of table top
The bore operation requirement at place, to improve the applicability of drilling rod auxiliary locator.
Above-mentioned telescopic rod main part is preferably connected and composed by inner tube 3-1 and outer tube 3-2 suit, is connected between inner and outer tubes
Be connected to radially be arranged press closer screw 3-4, press closer screw unclamp in the case where, be adjusted inner and outer pipes in axial direction
Relative position, to change the length of telescopic rod main part；And in the case where pressing closer screw and screwing, inner and outer pipe edge can be made
Axial direction forms limit.
Above-mentioned inner and outer tubes further preferably use seamless steel pipe structure, for example, inner tube uses 18*3 stainless steel tube,
Outer tube uses 25*2.5 seamless steel pipe.
Above-mentioned be welded further between the upper end of inner tube and the outside of support tube body reinforces support plate 2, with reality
Both existing securely connection, reinforcing support plate can be used the set square structure that outside described in attached drawing is arcwall face.
Above-mentioned support tube body is further made by opening notch processed on seamless steel pipe, for example, being 8cm in length, specification is
4cm wide notch is cut on the seamless steel pipe of 89*5 to be made.
Using this drilling rod auxiliary locator, before starting drilling, drilling rod is entangled with tubular support portion, adjusts upright bar portion
Divide length, withstands lower part top fork on ground or rack, alignment mark point can start to drill.
Although disclosing the embodiments of the present invention and attached drawing for the purpose of illustration, those skilled in the art can be with
Understand: departing from the utility model and spirit and scope of the appended claims, various substitutions, changes and modifications are all can
Can, therefore, the scope of the utility model is not limited to the embodiment and attached drawing disclosure of that.
