Abstract
The utility model relates to the stuck braking device of beam-pumping unit underneath type, the stuck braking device of this beam-pumping unit underneath type comprises base, depression bar, elastic rod, spring, shift fork, hook, depression bar is flexibly connected by axle with base, the other end and the shift fork of depression bar are fixed, one end and the shift fork of spring are fixed, the other end and the elastic rod of spring are fixed, and elastic rod is connected with the head of hook, and the other end of hook is flexibly connected by axle with base.The utility model is easy to operate safe and reliable again, when pumping unit quits work, after brake being checked, downward moulded rod, depression bar active force is delivered on hook by elastic rod, drives hook to move upward, when linking up with the draw-in groove faced on brake wheel, hook can direct stuck brake wheel.When link up with stagger with the draw-in groove on brake wheel time, link up with and be close on brake wheel under elastic force effect, brake, once the malfunctioning car that slips, can be guaranteed that brake wheel draw-in groove slips to and be stuck with when linking up with just pair.
Description
One, technical field:
The utility model relates to is the braking device of beam-pumping unit, and what be specifically related to is the stuck braking device of beam-pumping unit underneath type.
Two, background technique:
For ensureing the safety of every maintenance operations, the brake of beam-pumping unit must be safe and reliable.There is slipping car phenomenon not for preventing brake weight, current beam-pumping unit extensive use up-set type stuck braking device, its structure is as shown in (Fig. 1), draw-in groove 3 is had in brake wheel 1 periphery side, hinged brake hook 4 on reducer shell 2, the head of brake hook 4 can snap in draw-in groove 3 and play brake safety effect.This braking safety device has three shortcomings: first brake hook 4 is hinged on retarder, and hook and decoupling device must be climbed on retarder and operate, and not only waste time and energy, and there is very large potential safety hazard; Second when needing to open brake hook after the operations such as maintenance complete, very tight probably with draw-in groove card of brake hook, needs artificial crowbar to pry open, not only inconvenient operation, and slip car after prying open again and just form very big security threat to the operator on retarder; 3rd brake hook only enters draw-in groove under gravity, and brake hook is less with draw-in groove combination force, and unhook hidden danger is larger.
Three, summary of the invention:
The purpose of this utility model is to provide the stuck braking device of beam-pumping unit underneath type, and the stuck braking device of this beam-pumping unit underneath type operates the problem of the potential safety hazard that wastes time and energy, exists for solving the stuck braking device of existing beam-pumping unit up-set type.
The utility model solves the technological scheme that its technical problem adopts: the stuck braking device of this beam-pumping unit underneath type comprises base, depression bar, elastic rod, spring, shift fork, hook, depression bar is flexibly connected by axle with base, the other end and the shift fork of depression bar are fixed, one end and the shift fork of spring are fixed, the other end and the elastic rod of spring are fixed, elastic rod is connected with the head of hook, and the other end of hook is flexibly connected by axle with base.
In such scheme, base has horizontal edge and vertical edge, and base horizontal edge is fixed on speed reducer, and the head of hook is positioned at the below of brake wheel; Depression bar, elastic rod, hook are all positioned at the same side of base.
In such scheme, there is a semi-cylindrical hill joint of depression bar and base, and the top of this circular protrusions arranges depression bar fixed block.
Such scheme medi-spring is arranged in sleeve.
Beneficial effect:
1, the utility model is easy to operate safe and reliable again, when pumping unit quits work, after brake being checked, downward moulded rod, depression bar active force is delivered on hook by elastic rod, drives hook to move upward, when linking up with the draw-in groove faced on brake wheel, hook can direct stuck brake wheel.When link up with stagger with the draw-in groove on brake wheel time, link up with and be close on brake wheel under elastic force effect, brake, once the malfunctioning car that slips, can be guaranteed that brake wheel draw-in groove slips to and be stuck with when linking up with just pair.
2, the utility model improves on the basis of the stuck braking device of original up-set type, and without any change, structure is simple, low cost of manufacture for brake wheel.
Four, accompanying drawing illustrates:
Fig. 1 is the structural representation of the stuck braking device of up-set type;
Fig. 2 is the utility model off working state figure;
Fig. 3 is the stuck phase diagram of the utility model;
Fig. 4 is that the utility model treats stuck phase diagram.
1 brake wheel 2 reducer shell 3 draw-in groove 4 links up with 5 depression bar 6 base 7 speed reducing box base 8 elastic rod 9 sleeve 10 depression bar fixed blocks.
Five, embodiment:
Below in conjunction with accompanying drawing, the utility model is described further:
As shown in Figure 2, the stuck braking device of this beam-pumping unit underneath type comprises base 6, depression bar 5, elastic rod 8, spring, sleeve 9, shift fork, hook 4, base 6 has horizontal edge and vertical edge, base 6 horizontal edge is fixed on speed reducing box base 7, and depression bar 5, elastic rod 8, hook 4 are all positioned at the same side of base 6.Depression bar 5 is flexibly connected by axle with base 6, and depression bar 5 has a semi-cylindrical hill with the joint of base 6, and the top of this circular protrusions arranges depression bar fixed block 10.The side of circular protrusions is the pressure handle of depression bar 5, opposite side (i.e. the other end of depression bar) and the shift fork of circular protrusions are fixed, spring is arranged in sleeve 9, one end and the shift fork of spring are fixed, the other end and the elastic rod 8 of spring are fixed, elastic rod 8 is connected with the head of hook 4, and the other end of hook 4 is flexibly connected by axle with base 6.
When the utility model is installed, with bolt, base 6 is fixed on speed reducing box base 7, and notes making the head of hook 4 be positioned at the below of brake wheel 1.
Utility model works is divided into " brake " and " pinning " two step composition.When pumping unit quits work, after brake is checked, downward moulded rod 5, depression bar 5 active force is delivered on hook 4 by elastic rod 8, hook 4 is driven to move upward, as (Fig. 2) when facing the draw-in groove 3 on brake wheel when hook 4, hook 4 can direct stuck brake wheel 1 as (Fig. 3).When the draw-in groove 3 on hook 4 with brake wheel 1 staggers, as (Fig. 4), hook 4 is close on brake wheel 1 under elastic force effect, brake is once the malfunctioning car that slips, can guarantee brake wheel draw-in groove 3 slip to link up with 4 just pair time be stuck, during pumping unit start by the time, before start, first lift depression bar 5, and then releasing of brake handle.
