Abstract
The utility model relates to a kind of external contact type brake device for oil pumping machine in beam pumping unit field.Technological scheme: the brake block comprising two semicircle brake ferrules and the inner side connected by central shaft, it is characterized in that: in the middle of two semicircle brake ferrules, two secondary shafts are set respectively, by two secondary shafts, two semicircle brake ferrules are divided into four 90 degree of arc-shaped clamps, inside four 90 degree of arc-shaped clamps, set up brake block separately.Beneficial effect: no matter this technical guarantee brake hub is not or not central position, contacted with brake hub by the brake block inside rotation shaft regulated upper and lower two the 90 degree of arc-shaped clamps of secondary simultaneously, reach the object of even friction, and 90 degree of arc-shaped clamp right sides on 90 of bottom degree of arc-shaped clamps and top rotate backward, reach the object being convenient for changing top brake block, therefore this technology try out at the scene in good evaluation, be worthy of popularization.
Description
Technical field
The utility model relates to a kind of external contact type brake device for oil pumping machine in beam pumping unit field.
Background technique
Existing external contact type brake device for oil pumping machine mainly comprises the brake block of two semicircle brake ferrules and the inner side connected by central shaft, in actual motion, when brake hub to contact with brake block when rotating and brakes, might not in central position, brake hub sometimes with the upper contact of brake block, sometimes with the lower contacts of brake block, cause brake block top and the bottom to rub uneven, thickness is irregular, causes later stage braking effect bad, and the replacing of brake block is frequent, causes the wasting of resources.
Model utility content
The purpose of this utility model is for current condition, have developed a kind ofly to ensure that brake hub contacts evenly with each portion brake block, makes effective external contact type brake device for oil pumping machine.
Technological scheme: the brake block comprising two semicircle brake ferrules and the inner side connected by central shaft, it is characterized in that: in the middle of two semicircle brake ferrules, two secondary shafts are set respectively, by two secondary shafts, two semicircle brake ferrules are divided into four 90 degree of arc-shaped clamps, inside four 90 degree of arc-shaped clamps, set up brake block separately.
Beneficial effect: this technical guarantee brake hub departs from central position, contacted with brake hub by the brake block inside rotation shaft regulated upper and lower two the 90 degree of arc-shaped clamps of secondary simultaneously, reach the object of even friction, and 90 degree of arc-shaped clamp right sides on 90 of bottom degree of arc-shaped clamps and top rotate backward, reach the object being convenient for changing top brake block, therefore this technology try out at the scene in good evaluation, be worthy of popularization.
Accompanying drawing explanation
Accompanying drawing 1 is the structural representation of the present embodiment; Accompanying drawing 2 is when being convenient for changing top brake block, and 90 degree of arc-shaped clamps of bottom and 90 degree of arc-shaped clamp right sides on top rotate backward schematic diagram.
Embodiment
With reference to accompanying drawing 1, the present embodiment mainly comprises the brake block of two semicircle brake ferrules and the inner side connected by central shaft 2, two secondary shafts 3 are set respectively in the middle of two semicircle brake ferrules, by two secondary shafts 3, two semicircle brake ferrules are divided into four 90 degree of arc-shaped clamps, namely brake block 5 is set up separately inside 90 degree of arc-shaped clamps 4 of bottom and 90 degree of arc-shaped clamps, 1, four 90 degree of arc-shaped clamps on top.
