Description
Technical field
The utility model belongs to vertical oil-pumping machine, particularly relates to a kind of vertical oil-pumping machine two pincers synchronous mode pincers dish braking mechanism.
Background technique
The brake system of vertical oil-pumping machine is formed primarily of brake haft, transmission shaft, crotch connecting rod, electric hydaulic driving mechanism, slip caliper brake and brake disc.The brake disc that it utilizes sliding type caliper brake to hold tightly to be fixedly connected with reduction box input shaft is to realize the braking of vertical oil-pumping machine.Two wrench structures are coiled in general employing one, namely same brake disc install two sliding clamps, control respectively by electronic brake system and manual two kinds of driving mode.In use there is following problem in this structure: 1, electric brake system idle: because pumping unit is in field work environment for a long time, the safety reliability of electric brake system is poor, maintenance cost high, cause electric brake system availability low, leave unused for a long time; 2, braking force is not enough: above-mentioned two kinds of driving mode drive a break to provide braking force respectively, once cause action smooth due to structural member corrosion etc., just cannot provide enough braking force; 3, former brake self-locking mechanism adopts eccentric wheel self-locking, and pincers dish gap needs often to regulate along with the wearing and tearing of friction plate, adds complexity and the labor intensity of work on the spot.The vertical oil-pumping machine brake system of field construction is urgently improved, and it not only also exists potential safety hazard, also add the cost of Petroleum Production.
Model utility content
The utility model is to overcome deficiency of the prior art, a kind of vertical oil-pumping machine two pincers synchronous mode pincers dish braking mechanism is provided, former machine braking mechanism basis adopts two pincers lazy-tongs design, i.e. two sliding type caliper brake actions simultaneously, larger braking force is provided, ensures the reliability of brake function.
The utility model for achieving the above object, be achieved through the following technical solutions, a kind of vertical oil-pumping machine two pincers synchronous mode pincers dish braking mechanism, comprise brake haft, transmission shaft, crotch connecting rod, slip caliper brake and brake disc, brake haft and transmission shaft affixed, the transmission shaft the other end is connected with engaging lug, described engaging lug and crotch connecting rod pin joint, crotch small end and slip caliper brake pin joint, it is characterized in that: described crotch connecting rod front end U-shaped insert library is connected with connecting plate and the interlock connecting rod of first group of slip caliper brake respectively, the connecting plate of described interlock connecting rod front end U-shaped insert library pin joint second group of slip caliper brake, described first group of slip caliper brake and second group of slip caliper brake form two pincers synchronous mode pincers dish braking mechanism by interlock connecting rod.
Described brake haft and transmission shaft fixed connecting end are provided with ratchet and pawl arrangement, described ratchet and transmission shaft affixed, described ratchet be fixed in pawl base pin joint in frame.
Beneficial effect: compared with prior art, the utility model adds the quantity of the slip caliper brake simultaneously worked, and becoming two pincers brake, providing larger braking force from singly clamping brake; By improving the structure of brake lever, the braking force enabling brake lever provide reliable and stable, reach the effect strengthening braking.Structure is simple, and user cost is low.Adopt simple and reliable mechanical transmission component, not only saved device and purchased and user cost, and extend the cycle of device maintenance.Simple to operate, be easy to promote.Change existing single drive mode into by original two kinds of driving mode, eliminate loaded down with trivial details operating process, make operation become easy to learn.

Embodiment
Below in conjunction with preferred embodiment, to the embodiment provided according to the utility model, details are as follows: embodiment
Refer to accompanying drawing, the utility model provides a kind of vertical oil-pumping machine two pincers synchronous mode pincers dish braking mechanism, comprise brake haft 1, transmission shaft 2, crotch connecting rod 3, slip caliper brake and brake disc 4, brake haft and transmission shaft affixed, the transmission shaft the other end is connected with engaging lug 5, described engaging lug and crotch connecting rod pin joint, crotch small end and slip caliper brake pin joint, described crotch connecting rod front end U-shaped insert library 3-1 is connected with connecting plate and the interlock connecting rod 7 of first group of slip caliper brake 6 respectively, the connecting plate of described interlock connecting rod front end U-shaped insert library 7-1 pin joint second group of slip caliper brake 8, described first group of slip caliper brake and second group of slip caliper brake form two pincers synchronous mode pincers dish braking mechanism by interlock connecting rod.Remove the upper electro-hydraulic device of former vertical oil-pumping machine brake, adopt length-adjustable interlock connecting rod to be coupled together by two slip caliper brakes, realize two pincers and be synchronized with the movement.
Preferred version of the present utility model is, described brake haft and transmission shaft fixed connecting end are provided with ratchet and pawl arrangement 9, described ratchet 9-1 and transmission shaft affixed, described ratchet 9-2 be fixed in pawl base 9-3 pin joint in frame.Brake haft position increases the ratchet mechanism be made up of ratchet, ratchet and pawl base.Ratchet and pawl arrangement is arranged on the axle head of transmission shaft, and pawl base is welded in pumping unit shelf 10.
Working principle
Pull brake haft, brake haft rotates, and drives drive axis.Drive axis drives the movement of crotch connecting rod, masterpiece on crotch connecting rod is for the first slip caliper brake and interlock connecting rod, the connecting rod that simultaneously links drives the second slip caliper brake of top, two the slip caliper brakes up and down made work simultaneously, produce braking force, hold brake disc tightly, play braking action.
As shown in Figure 2, during braking, ratchet can slide axially on fitting seat, is moved axially to by ratchet and ratchet same position during use, engages with ratchet one-way because Action of Gravity Field ratchet naturally droops, and now can prevent brake hand from causing brake to be unclamped resilience at any time; During brake off, ratchet can be moved axially to depart from and engage with ratchet.
Braking gap adjustment is easy, and Safety performance is higher.Ratchet wheel detent mechanism is installed in the end of brake lever axle, and the moving range of brake clamp piece is large, does not need often to adjust pincers dish gap and just can ensure enough braking moments.When needs releasing ratchet is locked, the ratchet that must slide axially is just passable, prevents misoperation and locking inefficacy etc. from occurring unexpectedly, ensure that the reliability of braking effect.
Above-mentioned detailed description of this kind of vertical oil-pumping machine two pincers synchronous mode pincers dish braking mechanism being carried out with reference to embodiment; illustrative instead of determinate; several embodiments can be listed according to institute's limited range; therefore in the change do not departed under the utility model general plotting and amendment, should belong within protection domain of the present utility model.
