The regulator is characterized in that a frame (7) is arranged on the slide (1); a frame (7) is installed with a shaft (5) and a pawl axis (9); a fixed gear (3) is fixed on a ratchet (6); the pawl axes (9) is provided with a pawl (8) and a spring (10); a ratchet (6) and the pawl (8) are blocked with each other. A rack (2) that is meshed with the gear (3) is arranged inside the slide (1). The rack (2) is fixed on a jib (14). One end of the jib (14) extends out of the slide (1), and a roller (4) fixed on the end of the telescopic boom (14).
Description
Technical field:
The utility model relates to the belt tension device on the pumping unit in the oil recovery field, oil field, belongs to the semi-automatic regulator of a kind of belt of oil pumping machine.
Background technique:
In oil recovery field, oil field, pumping unit is the oil production equipment that generally uses, the power source of pumping unit is to be delivered to speed reducer by the band transmission by motor, relaxation phenomenon will appear after belt of oil pumping machine work a period of time, make motor idle running, belt slippage, belt are easy to damage, and need in time to adjust the slackness pumping unit ability proper functioning of belt.At present, mainly be that the motor base bolt is unclamped for the adjustment of belt of oil pumping machine, electric rotating machine base jackscrew moves forward and backward motor base to adjust the degree of tightness of belt, and this mode is adjusted belt to waste time and energy, inefficiency, the normal oil recovery of influence produced.
The model utility content:
The adjustment belt of oil pumping machine is wasted time and energy and the problem of working efficiency in order to solve, the utility model provides a kind of belt of oil pumping machine semi-automatic regulator, the characteristics of simple, easy to use, the time saving and energy saving and high working efficiency of the semi-automatic adjusting utensil structure of this belt of oil pumping machine.
The technical solution of the utility model is: the semi-automatic regulator of this belt of oil pumping machine comprises slideway, the slideway upper fixed has support, axle and pawl axis are installed on the support, be fixed with gear and ratchet on the axle, ratchet and spring are housed on the pawl axis, ratchet blocks mutually with ratchet, slideway is built-in with the tooth bar that is meshed with gear, tooth bar is fixed on the telescopic boom, and an end of telescopic boom stretches out outside the slideway, and the end of telescopic boom is fixed with running roller.
Above-mentioned slideway below has lock screw; Axle flexibly connects handle; The slideway outer wall is fixed with the grease nipple that communicates with its inner chamber.
The utlity model has following beneficial effect: owing to take such scheme, rotating the drive tooth bar by gear stretches out telescopic boom, running roller and belt are adjacent to, being rotated further gear can make belt tighten gradually, in this process, ratchet blocks with ratchet under spring action all the time mutually, make tooth bar can be under the tension force effect of belt reverse slide.As when changing belt, can pull the elastic force that ratchet overcomes spring ratchet and ratchet are broken away from, this moment, the backward rotation gear made telescopic boom drive the running roller withdrawal to get final product.This apparatus structure is simple, and is easy to use, time saving and energy saving, high working efficiency.
Description of drawings:
Accompanying drawing 1 is a structure sectional view of the present utility model;
Accompanying drawing 2 is A-A sectional views among Fig. 1;
Accompanying drawing 3 be among Fig. 2 B to view.

Embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
By Fig. 1 in conjunction with Fig. 2 and shown in Figure 3, the semi-automatic regulator of this belt of oil pumping machine comprises slideway 1, slideway 1 upper fixed has support 7, axle 5 and pawl axis 9 are installed on the support 7, be fixed with gear 3 and ratchet 6 on the axle 5, ratchet 8 and spring 10 are housed on the pawl axis 9, ratchet 6 blocks mutually with ratchet 8, slideway 1 is built-in with the tooth bar 2 that is meshed with gear 3, tooth bar 2 is fixed on the telescopic boom 14, and telescopic boom 14 is a square steel, and tooth bar 2 is at telescopic boom 14 inner bottom surfaces, the telescopic boom 14 upper bottom surface openings of tooth bar 2 correspondences, gear 3 is positioned at the opening of telescopic boom 14 upper bottom surfaces.One end of telescopic boom 14 stretches out outside the slideway 1, and the end of telescopic boom 14 is fixed with running roller 4.Slideway 1 below has lock screw 11, after the belt of oil pumping machine tensioner, screws lock screw 11 and pins tooth bar 2; Axle 5 flexibly connects handle 12, uses fashionable dress upper handle 12, and the time spent is not taken off handle 12; Slideway 1 outer wall is fixed with the grease nipple 13 that communicates with its inner chamber, utilizes the oil gun can oiling in slideway 1, and it is smooth and easy that telescopic boom 14 is slided in slideway 1.
During actual the use, this device is fixed on the pumping unit shelf of belt of oil pumping machine below, make the outer surface of running roller 4 corresponding with belt, crank handle 12 rotates axle 5, and telescopic boom 14 stretches out, running roller 4 is adjacent to belt, continue to shake handle 12, belt is tightened gradually under the effect of running roller 4, in this process, ratchet 8 blocks with ratchet 6 under spring 10 effect all the time mutually, make tooth bar 2 can be under the tension force effect of belt reverse slide.As when changing belt, can pull the elastic force that ratchet 8 overcomes spring 10 ratchet 8 and ratchet 6 are broken away from, this moment, backward rotation gear 3 made telescopic boom 14 drive running rollers 4 withdrawals to get final product.This apparatus structure is simple, and is easy to use, time saving and energy saving, high working efficiency.
