Description
Technical field
The present invention relates to a kind of manual pumping unit braking device, particularly a kind of driving mechanism of manual pumping unit braking device.
Background technique
Pumping unit will be braked pumping unit with braking device when stopping operation.The pumping unit braking device has manual pumping unit braking device.Manually the pumping unit braking device has brake handle, driving mechanism and the break that order links to each other.Break has the brake wheel of the oil pumping of can being installed on the arbor and is against the brake block on the brake wheel, and brake block is connected with the fork that drives the brake block action; Brake has the circular arc tooth plate base is arranged on the base, there is ratchet the tooth plate upper edge, is hinged with operating handle on the base, and there is handle the operating handle upper end, and the handle place is hinged with the ratchet pull bar, and there is the ratchet that is meshed with tooth plate upper edge ratchet the lower end of ratchet pull bar; Driving mechanism be hinged on brake the fork of operating handle and break between connecting rod, connecting rod has the waling stripe that is hinged and connected successively, commutate hinge and vertical links, and the length of connecting rod controlling device is arranged respectively on waling stripe and the vertical links.
During use; Hand-held handle pulled backwards operating handle drives the fork action through driving mechanism, and fork action drives brake block tightly is pressed on the brake wheel; Ratchet inserts ratchet and keeps constantly to the impacting force of brake wheel brake wheel being rotated by brake block, realizes the braking to pumping unit.The driving mechanism of this manual pumping unit braking device is a rigid rod; Before use; With the length that the length of connecting rod controlling device is regulated waling stripe and vertical links, let ratchet when inserting the steady state of a ratchet position, brake block can be pressed on the brake wheel tightly; This moment, the waling stripe and the vertical links of driving mechanism received tension force, and the tension force that waling stripe and vertical links receive is exactly the required tension force of pumping unit brake.
Manually the pumping unit braking device in use, the brake block on the break can have attenuate slightly because of wearing and tearing, after brake block has attenuate slightly; When if ratchet still inserts above-mentioned ratchet location brake; Brake block just can not be pressed on the brake wheel very tightly, for guarantee brake block attenuate is arranged slightly after brake block still can tightly be pressed on the brake wheel pulled backwards operating handle again; Let waling stripe and vertical links still receive the required tension force of above-mentioned brake, brake block is pressed on the brake wheel tightly.In the existing technology; It is rigid rod that ratchet has the waling stripe of a constant pitch, driving mechanism and vertical links, and pulled backwards joystick lever again after brake block has attenuate slightly is when letting waling stripe and vertical links receive the required tension force of brake; Ratchet generally is in the ratchet position of aforementioned stable state and the non-steady state position between ratchet position thereafter; Can not insert a back ratchet position of aforementioned stable state ratchet position, put down the ratchet pull bar after, ratchet still can slide and insert the ratchet position of aforementioned stable state; This moment, the waling stripe and the tension force that vertical links receives of driving mechanism were lax to some extent; Do not reach the required tension force of brake, make pumping unit when stopping operation brake, brake block can not be pressed on the brake wheel tightly.
Manually the pumping unit braking device in use; Brake block often takes place because of wearing and tearing attenuate is arranged slightly on the break; After brake block on the break has attenuate slightly because of wearing and tearing; Can regulate the length of waling stripe and vertical links through the length of connecting rod controlling device, recover to let ratchet when inserting the steady state of a ratchet position, brake block can be pressed on the brake wheel tightly.Because brake block is in use often because of the wearing and tearing attenuate; Brake block has attenuate just to need to regulate length of connecting rod slightly; Often regulate length of connecting rod and extremely bother,, will take place that brake block can not be pressed on the brake wheel tightly and the security incident that causes the pumping unit coaster in case regulate untimelyly.In addition, the length of connecting rod controlling device is the bolt and nut controlling device, is easy to get rusty at the on-the-spot screw thread of pumping unit, just is difficult to regulate length of connecting rod in case screw thread gets rusty.In actual production, pumping unit can not guarantee that safety shut-down is bigger potential safety hazard when stopping operation.
Summary of the invention
The objective of the invention is in order to overcome above-mentioned deficiency; Propose a kind of after brake block has attenuate slightly; During the pulled backwards joystick lever, ratchet can insert a back ratchet position of former steady state ratchet position, makes brake block be pressed in the pumping unit braking safety device on the brake wheel tightly again.
The present invention realizes with following method.
Brake handle, driving mechanism and break that the pumping unit braking safety device has order to link to each other; Break has the brake wheel of the oil pumping of can being installed on the arbor and is against the brake block on the brake wheel, and brake block is connected with the fork that drives the brake block action, and brake is base is arranged; The circular arc tooth plate is arranged on the base; There is ratchet the tooth plate upper edge, is hinged with operating handle on the base, and there is handle the operating handle upper end; The handle place is hinged with the ratchet pull bar; There is the ratchet that is meshed with tooth plate upper edge ratchet the lower end of ratchet pull bar, driving mechanism be hinged on brake the fork of operating handle and break between connecting rod, connecting rod has the waling stripe that is hinged and connected successively, hinge and vertical links commutate; The length of connecting rod controlling device is arranged respectively on waling stripe and the vertical links, be connected with on waling stripe or the vertical links and can make waling stripe or vertical links receive the elastic element of axial tensile force.
During use, when new brake block does not also have attenuate, during the brake of pumping unit braking safety device, ratchet is the steady state that is inserted in a ratchet position, and waling stripe and vertical links receive the required tension force that brakes.When after brake block produces attenuate, still accurately not regulating the length of rigid rod; The pulled backwards joystick lever, if still let waling stripe and vertical links receive the required tension force of brake, then ratchet is at the ratchet position of aforementioned stable state and the non-steady state between ratchet position thereafter; Because being connected with on waling stripe or the vertical links to make waling stripe or vertical links receive the elastic element of axial tensile force; The pulled backwards joystick lever can make the elastic element stress deformation further, and operating handle can overcome the resilient rear-moving of elastic element; Let ratchet insert the steady state of an above-mentioned back ratchet position; At this moment, waling stripe and vertical links receive the axial tensile force of elastic element, and waling stripe and vertical links have the required tension force of brake because of the axial tensile force that receives elastic element.
Be connected with on waling stripe of the present invention or the vertical links and can make waling stripe or vertical links receive the elastic element of axial tensile force; When after brake block produces attenuate, still accurately not regulating the length of rigid rod; The pulled backwards joystick lever; Ratchet can insert a back ratchet position of former steady state ratchet position, lets waling stripe and vertical links receive the axial tensile force of elastic element and has the required tension force of brake, and brake block is pressed on the brake wheel tightly.
