Description

Collection hopper that pneumatic rotary drilling rig used

Technical Field

The utility model belongs to the technical field of building engineering, a collection hopper that rig used is dug soon in pneumatics is related to, and more specifically is one kind in hard rock stratum construction, uses the collection hopper on the rig is dug soon in pneumatics.

Background

The construction of foundation pit support and pile foundation in building engineering is generally carried out by adopting a rotary drilling rig. The traditional rotary drilling rig drills through rotary cutting, the rock in certain areas is medium-hard rock, the traditional rotary drilling rig has the characteristics of complete rock and no development of bedding cracks, when the traditional rotary drilling rig is used for construction, the drilling efficiency is very low, and the loss to a drilling tool is large. Along with the development of the industry, the pneumatic rotary drilling rig is commonly used, and has the advantage of high hole forming efficiency.

At present, the existing pneumatic rotary drilling rig in the market mostly has the following defects in the using process: when the pneumatic rotary drilling rig is in construction, the drill bit performs hammering vibration under the action of gas to locally crush rocks, broken rock slag can be blown and floated in a drill hole under the action of the gas, and the rock slag can fall back to the bottom of the hole under the action of gravity. After repeated action for several times, very thick rock slag can be accumulated at the bottom of the hole, and the hole cannot be formed continuously due to the fact that the pneumatic rotary drilling bit cannot be directly contacted with the rock surface. Meet this condition, need to change the pick drill bit, take out the rock sediment of hole bottom to the rock face, at the pore-forming in-process, need frequent change pick to bore and the drill bit is dug to pneumatics soon, leads to the pore-forming efficiency to reduce.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the problem that the existing pneumatic rotary drilling rig needs frequent cutting pick drill bits to be replaced due to the deposition of rock slag in the pore-forming process, so that the pore-forming efficiency is reduced. Aiming at the defects in the technology, a collecting hopper device which is arranged at the upper part of a drill bit and is used for collecting rock slag is provided.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

a collecting hopper used by a pneumatic rotary drilling rig is characterized in that a collecting hopper barrel 1 is of a cylindrical structure, and the diameter of the collecting hopper barrel is smaller than that of a drill bit; the lower part of the collecting hopper cylinder 1 is symmetrically provided with a plurality of U-shaped openings as collecting hopper insertion grooves 2, and the bottom of the collecting hopper cylinder 1 is inserted at the upper part of the drill bit through the collecting hopper insertion grooves 2; a plurality of lifting hook interfaces 3 are uniformly arranged on the upper part of the collecting hopper barrel 1 along the circumference, and lifting hooks 4 of the collecting hopper are arranged on the lifting hook interfaces 3, so that the collecting hopper barrel 1 can be conveniently hoisted; and a plurality of positioning steel plates 9 are symmetrically arranged on the inner wall of the middle part of the collecting hopper cylinder 1.

The utility model has the advantages that:

1. the utility model discloses an aggregate bin can effectually collect the garrulous rock sediment of hitting, reduces to change the number of times that the pick drill carries out the clear hole.

2. The utility model discloses a collecting hopper adopts the connection form of couple, and it is convenient to dismantle, and collecting hopper is put forward the outer back of hole, and dismantlement that can be quick gets off is unloaded.

In the figure: 1, collecting hopper cylinder; 2, inserting a collecting hopper into a slot; 3 lifting the hook interface; 4, lifting and guiding hooks of the collecting hopper; 5, connecting a drill rod; 6, a drill wing plate; 7 drilling slag storage space; 8, rotary drilling a drill bit; 9 positioning the steel plate.

Detailed Description

The following description will further explain embodiments of the present invention with reference to the drawings and technical solutions.

As shown in fig. 1 and 2, the utility model relates to a collection hopper that pneumatic rotary drilling rig used, major structure are collection hopper barrel 1, adopt the diameter to be less than the steel drum of drill bit diameter, set up in the drill bit top.

The bottom symmetry of collecting hopper barrel 1 sets up collecting hopper inserting grooves 2, as shown in fig. 3, during the use, inserts collecting hopper inserting grooves 2 in the pterygoid lamina of drill bit, is connected the collecting hopper as an organic whole with digging drill bit 8 soon, and the space between collecting hopper barrel 1 inner wall and drill pipe joint 5 outer wall is regarded as boring sediment storage space 7 for the rock sediment that gets into in the collecting hopper can't flow out the collecting hopper along the hole.

A plurality of lifting hook interfaces 3 are symmetrically arranged at the upper end of the collecting hopper barrel body 1, and lifting in the dismounting process is realized through the matching of the collecting hopper lifting hook 4 and the lifting hook interfaces 3.

The symmetry is equipped with polylith location steel sheet 9 on the inner wall at collecting hopper barrel 1 middle part, and during installation collecting hopper barrel 1, if collecting hopper barrel 1 squints certain angle, polylith location steel sheet 9's inboard will lean on the impacter outer wall, and inclination is too big when preventing the installation of collecting hopper barrel 1.

The working process of the utility model is as follows:

1. before installing the drill bit, a steel wire rope is firstly adopted to be connected with a collecting hopper lifting hook 4, the collecting hopper lifting hook 4 is hung on a lifting hook interface 3, and the collecting hopper is hung on a power head;

2. and (4) lowering the drill rod, and installing the pneumatic rotary drilling bit on the drill rod.

3. And lifting the drill bit to enable the collecting hopper insertion groove 2 to be inserted into the drill bit wing plate 6, and completing the installation of the collecting hopper.

4. And (3) removing the connection between the lifting hook 4 in the aggregate bin and the steel wire rope.

5. And (6) aligning and forming holes by a drill bit.

6. Pore-forming to certain degree of depth, after the slag charge in the collecting hopper is piled up to full, promote the drilling rod, be connected wire rope and collecting hopper lifting hook 4 on the unit head, after connecting, transfer the drill bit and make the slag charge in the collecting hopper flow out the fill outside along the lower extreme, the slag charge in the drill bit pterygoid lamina region adopts the manual work to clear up. And circulating the steps to operate.
