Description
Technical field
The utility model relates to oil drilling and r eoovery machine technical field, and tackle arrangement is driven on the top that particularly relates to a kind of quick-replaceable brake pad of being convenient to quick-replaceable brake pad.
Background technology
At present, top is driven and is become one of essential product of oil drilling.With respect to traditional brill dish kelly bar operating type, top is driven and is adopted drill rod stand column to creep into, and can realize the operations such as circulating fluid, upper shackle, back reaming, has improved drilling efficiency and job safety.Use top to drive and can save drilling time 20%-25%, and can prevent the generation of lock of tool drilling.All there is significant lifting effect for horizontal well, inclined shaft, highly difficult directional well.
As everyone knows, drive on top is to be suspended on derrick by hook or tourist bus, by being contained on the guide rail of derrick inside, drives coaster connection and moves up and down, thereby realize drill-well operation by top.In order to reduce, coaster body is driven on top and the frictional force between coaster base is driven on top, engineers is driven coaster body and top and is driven between coaster base and be provided with brake pad on top, at present, above-mentioned brake pad is to be fixed by screws in top to drive on coaster base, find by long-term use link, in the time that above-mentioned brake pad need to be changed, engineers must be driven top to be put on platform, coaster body is separated with guide rail, after disassembling screw, just can change, then dismantle and install, said process is more loaded down with trivial details, and the efficiency that therefore causes changing brake pad is low.
Utility model content
The technical problems to be solved in the utility model is: provide a kind of top of the quick-replaceable brake pad of being convenient to quick-replaceable brake pad to drive tackle arrangement.
The technical scheme that the utility model is taked for the technical problem existing in solution known technology is:
Tackle arrangement is driven on a kind of top of quick-replaceable brake pad, comprise base body and brake pad, it is characterized in that: the multiple dovetail grooves that are provided with vertical direction in the inner side of described base body, each dovetail groove is communicating structure from top to bottom, in each dovetail groove, be provided with dovetail slide block, described brake pad is fixed by screws on described dovetail slide block, on the end face of described dovetail slide block, be provided with an internal thread hole, on an end face of described base body, be provided with the slide block pressing plate of restriction dovetail slide block movement, on another end face of described base body, be provided with guard shield, described slide block pressing plate is provided with a bolt hole.
As preferred version, the utility model has also adopted following technical scheme:
Described slide block pressing plate is installed on the bottom end face of base body, and described guard shield is installed on the top end face of base body, and the bottom opening of described dovetail groove is greater than its open top.
Advantage and the good effect that the utlity model has are: because the utility model is arranged at traditional brake pad on dovetail slide block, therefore in the time that needs are dismantled brake pad, only need to slide and shift out dovetail slide block, then after the complete brake pad of dismounting and change, reinsert fixed installation, first take off top with tradition and drive coaster, then dismounting and the installation that can carry out brake pad are compared, and have greatly improved operating efficiency; Because the bottom opening of dovetail groove is greater than its open top, therefore can prevent that dovetail slide block from skidding off from top, be also convenient to dovetail slide block and skid off from bottom simultaneously.
Brief description of the drawings
Fig. 1 is bottom of the present utility model partial sectional view;
Fig. 2 is top structure schematic diagram of the present utility model;
Fig. 3 is use state diagram of the present utility model.
Wherein: 1, base body; 2, dovetail slide block; 3, brake pad; 4, slide block pressing plate; 5, guard shield; 6, guide rail; 7, reduction box is driven on top.
Detailed description of the invention
For further understanding utility model content of the present utility model, Characteristic, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
Refer to Fig. 1, Fig. 2 and Fig. 3, tackle arrangement is driven on a kind of top of quick-replaceable brake pad, comprise base body 1 and brake pad 3, wherein: the cross section of base body 1 is " C " font, be provided with multiple dovetail grooves of vertical direction in the inner side of base body 1, each dovetail groove is communicating structure from top to bottom, in each dovetail groove, be provided with dovetail slide block 2, brake pad 3 is fixed by screws on dovetail slide block 2, on the end face of dovetail slide block 2, be provided with an internal thread hole, on an end face of base body 1, be provided with the slide block pressing plate 4 that restriction dovetail slide block 2 moves, on another end face of base body 1, be provided with guard shield 5, slide block pressing plate 4 is provided with a bolt hole.As preferred embodiment, this specific embodiment is installed on slide block pressing plate 4 on the bottom end face of base body 1, in order to prevent that greasy dirt, rainwater from entering dovetail groove, on the end face of the top of base body 1, guard shield 5 is installed; For the ease of insertion and the extraction of dovetail slide block 2, dovetail groove is the dovetail groove with tapering, and the bottom opening of dovetail groove is greater than its open top.In tackle arrangement when work, is driven on top, and base body 1 is placed on the outer wall of guide rail 6, and the outer wall of base body 1 is driven reduction box 7 and is installed on top, pushes up like this to drive reduction box 7 and move up and down along guide rail 6 under the drive of base body 1.
The detailed process that tackle arrangement replacing brake pad 3 is driven on top in above-mentioned specific embodiment is:
Step1, slide block pressing plate 4 is disassembled from base body 1.
Step2, percussion hammer is screwed in the internal thread hole on base body 1 bottom dovetail slide block 2, utilizes percussion hammer that dovetail slide block 2 is pulled out in coaster body 1; Above-mentioned Step2 can also adopt following steps to replace: dismounting guard shield 5, by knocking base body 1 top dovetail slide block 2, makes dovetail slide block 2 separate with coaster body 1; Then guard shield 5 use bolts are reinstalled in to the top of base body 1.
Step3, the bolt being connected with brake pad 3 on the dovetail slide block 2 disassembling is twisted off to i.e. replaceable new brake pad 3.
Step4, the brake pad of more finishing changing 3 use bolts and dovetail slide block 2 are tightened again.
Step5, dovetail slide block 2 is inserted from the bottom dovetail groove of base body 1.
Step6, with bolt, slide block pressing plate 4 is arranged on to the bottom of coaster body 1.
Step7, insert the bolt hole on slide block pressing plate 4 with bolt, and then dovetail slide block 2 is carried out fastening, anti-limited slip block pressing plate 4 moves in dovetail groove.
Above embodiment of the present utility model is had been described in detail, but described content is only preferred embodiment of the present utility model, can not be considered to for limiting practical range of the present utility model.All equalization variation and improvement etc. of doing according to the utility model application range, within all should still belonging to patent covering scope of the present utility model.
