Description
Technical field:
The utility model relates to a kind of pumping unit braking safety device that is used for pumping well, belongs to the oil recovery machiner class.
Background technique:
For a long time, beam pumping unit is the most widely used a kind of oil recovery machiner of oilfield always.When the pumping unit stop pumping is overhauled, need the apply the brakes device that pumping unit is checked, to guarantee oil recovery worker and the personal safety of maintainer in maintenance process.At present, the braking device that on-the-spot beam pumping unit usually adopts mainly is the slip-type brake, and this kind braking device causes brake failure because of machinery or manual operation reason sometimes, and causes security incident.
The model utility content:
The purpose of this utility model is to provide a kind of safe dual fail-safe interlocking type pumping unit braking device that can guarantee to brake when the pumping unit stop pumping is overhauled reliably, guarantee.
The utility model is to realize like this.This kind braking device is by the main brake handle, the main brake fixed ratchet wheel, the auxiliary brake handle, the interlocking pin, the auxiliary brake fixed ratchet wheel, main, auxilliary brake steering base, drag link, vertical connecting rod, connect bearing pin, swing arm, fixedly swing arm rotating shaft, swing arm pull bar bearing pin, right ratchet pull bar, right ratchet, right ratchet bearing pin, right ratchet extension spring, right ratchet extension spring fixing bolt, swing arm push rod bearing pin, the left pawl push rod, left pawl extension spring fixing bolt, the left pawl extension spring, the left pawl bearing pin, left pawl, the ratchet rotating shaft, the brake wheel assist ratchet, support is formed.Main brake handle and main brake fixed ratchet wheel side are equipped with auxiliary brake handle and auxiliary brake fixed ratchet wheel, main brake being provided with the interlocking pin; Auxiliary brake is equipped with drag link to the bottom, the drag link the other end links to each other with steering base upper end on being installed in oil pumping unit base, the steering base the other end links to each other with vertical connecting rod, the vertical connecting rod upper end links to each other with the swing arm left end by connecting bearing pin, swing arm is fixed on the support upper end by fixing arm shaft, the swing arm upper end links to each other with right ratchet by swing arm pull bar bearing pin, right ratchet pull bar, pull bar bearing pin, and the swing arm lower end links to each other with left pawl by swing arm push rod bearing pin left pawl push rod left pawl push rod bearing pin; Left pawl and right ratchet are the coaxial left-right setting, can freely rotate around the ratchet rotating shaft, and the ratchet rotating shaft is fixed on the pumping unit brake tile rotating shaft exterior edge face; Right ratchet extension spring left end is fixed on the right ratchet bearing pin, and right-hand member is fixed on the right ratchet extension spring fixing bolt of right ratchet pull bar right-hand member.Right ratchet bearing pin can slide in right ratchet pull rod slot; Left pawl extension spring left end is fixed on the middle left pawl extension spring fixing bolt of left sour jujube push rod, and right-hand member is fixed on the left pawl push rod bearing pin, and left pawl push rod bearing pin can slide in the elongated slot of left pawl push rod right-hand member, and two extension springs will leave prefastening force when mounted; The brake wheel assist ratchet, locate by former brake wheel cylindrical exterior edge face, ratchet is leaned against the former brake wheel outside, be fixed on the brake wheel with U bolt, make itself and former brake wheel coaxial, synchronous, support becomes 45---60 degree angle lapping tiltedly to be fixed on the speed reducer brake wheel hubcap outside with former brake axle bolt of cover with level; Main brake fixed ratchet wheel, auxiliary brake fixed ratchet wheel and main brake steering base, auxiliary brake steering base all are fixed on the oil pumping unit base.
During this braking device work, the front and back push-and-pull campaign of auxiliary brake handle drives drag link, steering base, vertical connecting rod, swing arm, right ratchet pull bar, spur right ratchet bearing pin by extension spring and drive right ratchet and rise and fall, the left pawl push rod promotes left pawl by extension spring pulling left pawl bearing pin and rises and falls simultaneously.When ratchet falls, stop as the ratchet boss, this ratchet can be pressed on the ratchet boss, this ratchet bearing pin extension spring slides in right ratchet pull bar or left pawl push rod groove, and another ratchet can not wait in another boss spacing that falls into ratchet because of two ratchet boss spacing arc length and a certain integral multiple arc length of ratchet boss spacing.When brake wheel has trace to rotate, be pressed in the ratchet on the brake ratchet boss, fall in the ratchet boss spacing in the effect of spring, make this brake dual fail-safe more firm.During the pumping unit stop pumping, at first turn off the pumping-unit motor power supply, the tension main brake, after pumping unit stops, the pulling auxiliary brake, promoting swing arm by drag link, steering base, vertical connecting rod clockwise rotates, swing arm promotes right ratchet pull bar, pulling left pawl push rod, and two ratchets sway about driving by two extension springs again, make it have at least a ratchet to block brake wheel ratchet boss, can realize the pumping unit brake.Pumping unit opens when taking out, and at first promotes the auxiliary brake handle, by drag link, steering base, swing arm, left pawl push rod and right ratchet pull bar pull-up ratchet, removes auxiliary brake, unclamps main brake again, and power-on can realize that pumping unit opens and take out.Open when taking out and last lever is blocked the auxiliary brake handle, make it and to pull back, thereby realize safety interlock owing to main brake.
The utility model is reasonable in design, and installation, easy and simple to handle can be implemented in arbitrary location brake, and two ratchets can be worked simultaneously when pumping unit has trace movement, thereby be realized safe dual fail-safe.Owing to adopted pawl ratchet formula structure, thereby pumping unit can be stopped and extremely and not slide, owing to be provided with interlock, thereby can not misoperation occur and damage machinery.Utilize this device can effectively avoid the production accident that causes because of the malfunctioning pumping unit running of main brake, guarantee the pumping well production safety.
