Description

Rig tension weight churning, detection, protector

Technical field

The utility model relates to a kind of geological drilling device, particularly a kind of rig tension weight churning, detection, protector.

Background technology

Carrying out in the wild in geological drilling process, often to be adopted tension weight churning to carry out creeping into, detecting, its principle promotes after weight to certain altitude, unclamps volume and raises, and allows weight free-falling, and drilling tool enters in the ground body of underground under the effect of tension weight churning power. Weight is connected with wireline by U-shaped ring and pin, the work of weight has the feature of continuity, repeatedly cyclicity, and pin and pin are fixed under being stuck in cyclic load effect, is easy to fatigure failure occur and ruptures, and there is no omen before fracturing, have sudden. Fixing card or pin can cause pin to come off after rupturing, and pin is fallen in the air from height, and the personnel safety of ground handling personnel is produced very big harm. Simultaneously when carrying out extra-heavy type circular cone dynamic sounding in situ test, need to use extra-heavy type circular cone dynamic sounding instrument to carry out, but the complicated operation of extra-heavy type dynamic penetrometer, work discontinuous, efficiency is low, manning is many, with high costs, there is certain defect in use, and utilize common tension weight churning device cannot reach the effect of extra-heavy type dynamic sounding.

Summary of the invention

The utility model is to solve the above-mentioned deficiency existing for prior art; a kind of structure is proposed simple; design ingenious; rationally distributed; the fixing card of pin or pin can be prevented from high falling to eliminate safe hidden trouble, the rig tension weight churning of extra-heavy type dynamic sounding, detection, protector can also be substituted simultaneously.

Technical solution of the present utility model is: a kind of rig tension weight churning, detection, protector, it is characterized in that: described percussion mechanism comprises hollow hammer core cylinder 1, the bottom of hammer core cylinder 1 has been threaded drilling tool 2, in hammer core cylinder 1, activity is socketed with weight body 3, the bottom of weight body 3 is provided with pallet 4, the top of weight body 3 is connected with U-shaped ring 6 by pin 5, and it is provided with fixing card 7 with pin 5 matches, U-shaped ring 6 is connected with wireline 8, the anti-fall cylinder 9 of upper end open it is provided with on the top of weight body 3, anti-fall cylinder 9 is by described pin 5, in U-shaped ring 6 and fixing card 7 are all wrapped in.

The lift height of described weight body 3 is 1m, and the quality of weight body 3 is 120kg.

Compared with the existing technology, tool has the following advantages the utility model:

The rig tension weight churning device of this kind of structure formation, its structure is simple, design ingenious, rationally distributed, it blocks, with fixing, the problem easily rupturing because of fatigure failure, falling and hurt sb.'s feelings for the pin that traditional tension weight churning device is in use existing, designs a kind of special structure, and its anti-fall cylinder can when pin and fixing card come off, prevent it from high falling, it is to increase the security in this plant running process; Simultaneously the lift height of its counterweight hammer body and quality are all optimized design so that it is can substitute overweight dynamic penetrometer completely. Utilize this device both can carry out on-the-spot in situ test, percussion drilling can be carried out again, thus reach raising efficiency, improve security, the object reduced costs. And its manufacture craft is simple, cheap for manufacturing cost, therefore it may be said that it has possessed multiple advantage, is particularly suitable for applying in the art, and its market outlook are very wide.

Accompanying drawing explanation

Fig. 1 is the structural representation of the utility model embodiment state one.

Fig. 2 is the structural representation of the utility model embodiment state two.

Embodiment

Below in conjunction with accompanying drawing, embodiment of the present utility model is described. such as Fig. 1, shown in Fig. 2: a kind of rig tension weight churning, detection, protector, it comprises a hollow hammer core cylinder 1, be threaded drilling tool 2 in the bottom of hammer core cylinder 1, in hammer core cylinder 1, activity is socketed with weight body 3, the bottom of weight body 3 is provided with pallet 4, this pallet 4 be positioned at hammer core cylinder 1 and along its axial motion, it is connected with U-shaped ring 6 by pin 5 on the top of weight body 3, it is provided with fixing card 7 with described pin 5 matches, wireline 8 then it is connected with at the top of U-shaped ring 6, the other end of this wireline 8 is connected with windlass structure, anti-fall cylinder 9 also it is provided with on the top of weight body 3, the top end opening of this anti-fall cylinder 9, and anti-fall cylinder 9 is by above-mentioned pin 5, in U-shaped ring 6 and fixing card 7 are all wrapped in, lift height by described weight body 3 is designed to 1m simultaneously, and the quality of weight body 3 is 120kg.

The working process of the rig tension weight churning of the utility model embodiment, detection, protector is as follows: first allow drilling tool 2 keep perpendicular to the ground and contact, then windlass structure is started, weight body 3 is pulled to rise by wireline 8, in the process that weight body 3 rises, the pallet 4 of its bottom is along the axial motion of hammer core cylinder 1, until moving to the top of hammer core cylinder 1, after weight body 3 motion puts in place, windlass structure unclamps, weight body 3 free-falling under the effect of deadweight, hammer core cylinder 1 is impacted by the pallet 4 of its bottom, and drilling tool 2 is squeezed into stratum; So repeated multiple times continuously, until completely drilling tool 2 being squeezed in stratum; In above-mentioned working process, if pin 5 and fixing card 7 rupture because of fatigure failure, also can not directly fall bottom surface from eminence, but fall into anti-fall cylinder 9, now windlass structure cannot pull weight body 3 to rise, operator just can judge that pin 5 and fixing card 7 rupture, and again changes pin 5 and fixing card 7; Simultaneously owing to the lift height of weight body 3 in this kind of percussion mechanism is 1m, and the quality of weight body 3 is 120kg, therefore when weight body 3 falls, the striking energy of its kinetic energy provided and extra-heavy type dynamic sounding hammer can keep always, and work can be contacted, therefore it completely can the extra-heavy type dynamic sounding hammer of alternate country standard, for carrying out on-the-spot in situ test.
