Description
Technical field
This utility model relates to the structure of oilfield overhaul workover rig, particularly relates to the structure of the rotating disk brake unit of workover rig.
Background technology
Old XJ350 workover rig is band hub brake unit without rotating disk brake unit, old XJ550 workover rig because of rotating disk brake unit, and braking effect is poor, slipping of brake often occurs.In overhaul is constructed, produce bigger reactive torque due to drilling rod deformation energy, driller can only take repeatedly and, the mode of point disk clutch to be to control rotating disk speed reversal.There is great potential safety hazard.
The scheme that the brake unit of current domestic workover rig rotating disk drive system uses is: push-plate clutch rotating disc drive box, is furnished with push-plate brake gear on driving box, by pneumatic control, rotating disk drive system is carried out braking.Such as the brake unit repacking used according to current domestic workover rig rotating disk drive system.Rotating disc drive box to be increased and rotating disk change speed gear box, it is necessary to install positive and negative change speed gear box and band push-plate clutch and the assembly apparatus such as transfer case of push-plate brake additional.The parts such as power transmission shaft to be reequiped, drive chain case, waste time and energy, and workload is big, and repacking cost is high；And the rotary countershaft at XJ350 workover rig ride rear portion does not has sufficient space to meet requests for alternations because of position problems.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, it is provided that the workover rig rotating disk Pneumatic and hydraulic clamping disk brake device of a kind of good braking effect.
The purpose of this utility model is achieved in that workover rig rotating disk Pneumatic and hydraulic clamping disk brake device, including bearing cover, the first flange and the second flange, described brake unit also includes brake disc, the inward flange of brake disc is arranged between the first flange and the second flange, and brake disc and the first flange, the second Flange joint；On described bearing cover, fixing connection fixed support, connects hydraulic jaw type brake on fixed support；Described hydraulic jaw type brake includes caliper, caliper arranges two blocks of brake(-holder) blocks, every block of brake(-holder) block is all fixed with caliper by spacing steady pin, at least one pair of plunger is set in caliper, one end of each plunger props up corresponding brake(-holder) block after all stretching out caliper, the outward flange of described brake disc is arranged between two blocks of brake(-holder) blocks.
The brake disc that this utility model Design and Machining matches with hydraulic jaw type brake, if XJ350 workover rig, hydraulic jaw type brake is arranged on rotating disk drive chain case by fixed support, is fixed on by brake disc between XJ350 workover rig rotating disk drive chain case power shaft flange (the second flange) and transmission shaft flange (the first flange)；If XJ550 workover rig, hydraulic jaw type brake is arranged on transmission case by fixed support, is fixed on by brake disc between XJ550 workover rig transmission case output shaft flange (the second flange) and transmission shaft flange (the first flange)；Brake being connected with hydraulic pump with hydraulic line, when gases at high pressure act on high-pressure pump, in promotion lubricating cup, hydraulic oil acts on and realizes braking in hydraulic jaw type brake.During braking, pressure oil liquid enters caliper inner chamber from hydraulic fluid port, makes the plunger of both sides stretch out simultaneously, holds the brake(-holder) block of both sides tightly brake disc.When pressure oil liquid oil return, plunger return makes brake(-holder) block take-off the brake dish, releases braking.
Advantage of the present utility model: 1, braking moment is unrelated with the direction of motion, easily reequips；2, Heat stability is good, easy heat radiation, and size are little, light weight；3, working stability, good braking effect, the life-span is long；Adapt to extremely harsh climate condition；4, pressure distribution is uniform, brake(-holder) block even wearing；5, simple to operate, low price, easy to maintenance.By this brake unit, control the release of drilling rod reactive torque so that it is can not act directly in workover rig drive system, thus drive system is implemented protection, it is ensured that the safe operation of rotating disk, eliminate potential safety hazard.
Preferably, described plunger has four, and two of which plunger props up one block of brake(-holder) block after stretching out caliper, and two other plunger props up another block brake(-holder) block after stretching out caliper, and four plungers make to brake quicker, stable, reliable.
Preferably, described brake disc passes through bolt and the first flange, the second Flange joint.

Detailed description of the invention
As Figure 1-4, workover rig rotating disk Pneumatic and hydraulic clamping disk brake device, including the first flange the 12, second flange 8 and brake disc 6, in figure as a example by XJ550 workover rig, first flange 12 is arranged on transmission case output shaft, and the second flange 8 is arranged on one end of power transmission shaft.The inward flange of brake disc 6 is arranged between the first flange 12 and the second flange 8, and brake disc 6 is connected with first flange the 12, second flange 8 by bolt 7.
Brake unit also includes the fixed support 3 being fixedly connected on the casing bearing cover 2 of transmission case, and casing bearing cover 2 is connected on the casing 1 of workover rig transmission case, connects hydraulic jaw type brake 9 on fixed support 3.
Hydraulic jaw type brake 9 includes caliper 10, caliper 10 arranges two blocks of brake(-holder) blocks 4, every block of brake(-holder) block 4 is all fixed with caliper 10 by spacing steady pin 11, four plungers 5 are set in caliper 10, two of which plunger 5 props up one block of brake(-holder) block 4 after stretching out caliper 10, two other plunger 5 props up another block brake(-holder) block 4 after stretching out caliper 10, the outward flange of brake disc 6 is arranged between two blocks of brake(-holder) blocks 4.
As it is shown in figure 5, make high-pressure pump promote hydraulic total pump to make hydraulic oil in lubricating cup act on braking fluid cylinder by operation disk combination valve realize hydraulic jaw type brake.1) when operating handle and pushing location A to from stop position, the pressure-air effect of the 0.7MP in gas receiver makes disk clutch combine；2) by location A when position B gradually promotes；Engine throttle gradually rises, and rotary speed is also gradually increased；Otherwise reduce；When handle returns to location A, idling is down to by electromotor, and rotating disk stops operating and occurs reversion under reaction torque effect.3) now descending handle to put in place and put C, rotating disk is braked immediately；4) when operating work in every stopping when handle returns to middle position.
