Abstract
The utility model relates to puncheon centralizing device before vertical shaft umbrella bores, comprise pedestal and U-shaped maintenance mouth, pedestal is provided with the recess matched with the segmental arc of U-shaped maintenance mouth, U-shaped maintenance mouth is fixedly connected on base notch place by the segmental arc of self, and the openend of U-shaped maintenance mouth is used in progradation, carrying out screens to drill rod.U-shaped maintenance mouth is the U-shaped maintenance mouth of alloy steel.The utility model effectively can avoid original-pack puncheon centralizing device annular closing structure clogging of causing under rock dust is piled up, in reply rock drilling operation drill steel frequently to rock wearing and tearing comparatively effective.
Description
Technical field
The utility model relates to a kind of component of vertical shaft umbrella bores propeller part.
Background technology
It is main rock drilling equipment that umbrella is drilled in shaft construction, and the height of rock penetration performance has direct impact to programming.Puncheon centralizing device is that umbrella bores angle of rake important component, before existing vertical shaft umbrella bores, the structure of puncheon centralizing device as shown in Figure 1, comprise the parts such as pressing plate 1, bolt 2, riser 3, slide rail 4, clamping plate 5, base plate 10, the notch part of pressing plate and riser forms annular closing structure, the clogging caused under rock dust is piled up, and angle of rake front puncheon centralizing device due in operation very near work plane rock stratum, damage problem very serious.According to job site statistics, often before cover, the life cycle of puncheon centralizing device only has 10 days.Six general arm umbrellas bore original-packly altogether has puncheon centralizing device before six covers, is normally monthly just need change 18 covers under condition of construction, not only increases cost, and delay rock drilling progress.
Summary of the invention
In order to solve the short technical problem of existing angle of rake front puncheon centralizing device life cycle, it is strong that the utility model provides a kind of durability, and cost of manufacture is low, still can play the novel front puncheon centralizing device of guide effect same with original-pack puncheon centralizing device in rock drilling, and be easy to processing, be convenient to promote the use of.
Technical solution of the present utility model is as follows:
Puncheon centralizing device before vertical shaft umbrella bores, its special character is: comprise pedestal and U-shaped maintenance mouth, described pedestal is provided with the recess matched with the segmental arc of U-shaped maintenance mouth, described U-shaped maintenance mouth is fixedly connected on the indent on pedestal by the segmental arc of self, the openend of U-shaped maintenance mouth is used in progradation, carrying out screens to drill rod.
Be more than basic structure of the present utility model, based on this basic structure, following improvement can also be made:
Above-mentioned U-shaped maintenance mouth is the U-shaped maintenance mouth of alloy steel.
Further, the segmental arc of above-mentioned U-shaped maintenance mouth and pedestal continuous welding, intensity is high, is applicable to the occasion that the vibration of this operating mode is large, have shock.
Said base comprises trapezoidal portions, and described recess is arranged on the small end of trapezoidal portions, and trapezoidal is the widening structure being transitioned into riser by U-shaped maintenance mouth.
Further, said base also comprises rectangle part, and the large end of described trapezoidal portions is connected with rectangle part.
Further, above-mentioned rectangle part arranges bolt hole.
Compared with prior art, advantage is the utility model:
1, the opened type structure of the utility model puncheon centralizing device is in drill steel drilling process, effectively can avoid the clogging that original-pack puncheon centralizing device annular closing structure causes under rock dust is piled up.
2, the U-shaped mouth of the utility model puncheon centralizing device screens drill steel uses alloy steel material to make, in reply rock drilling operation drill steel frequently to rock wearing and tearing comparatively effective.
3, the utility model puncheon centralizing device is simple relative to original-pack puncheon centralizing device structure, and component are few, not fragile in its use close to work plane rock stratum.
4, of the present utility model in normal rock drilling operation life cycle can extend to 5 months, effectively reduce use cost.
Accompanying drawing explanation
Fig. 1 is the structure chart of existing front puncheon centralizing device.
Fig. 2 is structure chart of the present utility model.
Wherein Reference numeral is: 1-pressing plate, 2-bolt, 3-riser, 4-slide rail, 5-clamping plate, 10-base plate, 6-U type maintenance mouth, 7-pedestal, 8-continuous weld, 9-bolt hole.
Detailed description of the invention
Below in conjunction with accompanying drawing 1-2, the utility model is described in detail.
The utility model uses alloy steel to make the puncheon centralizing device of U-shaped unenclosed construction, the original-pack puncheon centralizing device of the irony ring seal structure shown in alternate figures 1.The utility model puncheon centralizing device comprises pedestal 7 and U-shaped maintenance mouth 6 two parts.The effect of pedestal 7 is that puncheon centralizing device integral installation is bored propeller front end at umbrella, and the effect of U-shaped maintenance mouth 6 in progradation, carries out screens to drill rod.
Figure 2 shows that a preferred embodiment of the present utility model, before vertical shaft umbrella bores, puncheon centralizing device comprises pedestal 7 and U-shaped maintenance mouth 6, pedestal 7 is provided with the recess matched with the segmental arc of U-shaped maintenance mouth, U-shaped maintenance mouth is fixedly connected on base notch place by the segmental arc of self, and the openend of U-shaped maintenance mouth is used in progradation, carrying out screens to drill rod.U-shaped maintenance mouth is the U-shaped maintenance mouth of alloy steel.The segmental arc of U-shaped maintenance mouth and pedestal continuous welding.Pedestal comprises trapezoidal portions and rectangle part, and recess is arranged on the small end of trapezoidal portions.The large end of trapezoidal portions is connected with rectangle part.The parts such as the utility model and slide rail, clamping plate and base plate are combined and form puncheon centralizing device independently, the bolt hole 9 of rectangle part also can be utilized to be connected by the riser of the utility model with existing front puncheon centralizing device, to repair existing front puncheon centralizing device.Pedestal of the present utility model adopts steel plate to make.
