Abstract
The utility model relates to a novel hydraulic chain tightener. The novel hydraulic chain tightener is characterized in that a hand pump (5) provides power for a hydraulic cylinder (2), a hydraulic pipeline (3) is arranged on one side of the hydraulic cylinder (2) and communicated with the hand pump (5), fixing rings (6) are arranged on the two sides of a cylinder body of the hydraulic cylinder (2), chains (7) are arranged on the fixing rings (6), and the end of each chain (7) is provided with a hook (1). The working principles of the hydraulic cylinder and the hand pump are fully utilized, pressure is matched, and the tensioning force of the chains is accurately controlled through conversion; operation is easy, time and labor are saved, it is ensured that the tensioning force of the chains is within the reasonable and accurate range, the security coefficient of downhole working personnel is increased, the overall service life of a scraper is prolonged, and the cost of coal mining is lowered.
Description
Technical field
The utility model relates to coal excavation apparatus field, is specifically related to a kind of novel hydraulic chain tensioner sheet.
Background technology
Most domestic scrapper conveyor manufacturing enterprise is when test run and down-hole installation at present, and the tensioning of chain is generally by manually operating by rule of thumb; Very easily there is the fracture of chain tension or the inadequate situation of tensile force in the error in judgement due to misoperation or individual in the process of tension chain; The fracture of chain tension easily damages operating personal, has potential safety hazard; Tensile force affects not again the whole service life of scrapper conveyor, increases productive costs.
Summary of the invention
The purpose of this utility model is in order to overcome the defect of prior art, tight chain process to be monitored in real time, thereby efficiently solves problems of the prior art.
For realizing the technical scheme that the object of the utility model hydraulic tightener for motorcycle engine chain takes, be: a kind of novel hydraulic chain tensioner sheet, it is characterized in that fuel priming pump (5) provides power for hydraulic actuating cylinder (2), hydraulic tubing (3) is located at hydraulic actuating cylinder (2) one sides and is communicated with fuel priming pump (5); Hydraulic actuating cylinder (2) cylinder body both sides are provided with set collar (6), and set collar (6) is provided with chain (7), and chain (7) termination is provided with hook (1).
Described fuel priming pump (5) is provided with compression indicator (4).
Described chain (7) is two.
The beneficial effects of the utility model are: make full use of the principle of work of hydraulic actuating cylinder, fuel priming pump, and join pressure, by converting, chain tension is accurately controlled.Simple to operate, time saving and energy saving, and guaranteed that chain tension, in reasonable, accurate scope, has improved underground work personnel's safety factor, extended the whole service life of scrapper conveyor, reduced mining costs.
Accompanying drawing explanation
Fig. 1 is the utility model schematic diagram;
In figure: 1-hook, 2-hydraulic actuating cylinder, 3-hydraulic tubing, 4-compression indicator, 5-fuel priming pump, 6-set collar, 7-chain.
The specific embodiment
Below in conjunction with accompanying drawing, principle of the present utility model and feature are described, example, only for explaining the utility model, is not intended to limit scope of the present utility model.
Embodiment 1: see Fig. 1, a kind of novel hydraulic chain tensioner sheet, is characterized in that fuel priming pump 5 provides power for hydraulic actuating cylinder 2, and hydraulic tubing 3 is located at hydraulic actuating cylinder 2 one sides and is communicated with fuel priming pump 5; Hydraulic actuating cylinder 2 cylinder body both sides are provided with set collar 6, and set collar 6 is provided with chain 7, and chain 7 terminations are provided with hook 1.
Described fuel priming pump 5 is provided with compression indicator 4.
Described chain 7 is two.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
