Abstract
The utility model provides a chain tensity testing device. The chain tensity testing device can adjust chain tensity, effectively avoid chain dropping and prolong service life of equipment. The chain tensity testing device comprises a machine frame and a chain wheel, the chain wheel meshes with and drives the chain, and a chain plate is fixed on the chain. The chain tensity testing device is characterized in that the machine frame is provided with a slide rail, a wheel shaft of the chain wheel is installed on a slide block, the slide block is installed on the slide rail, the slide block is connected with a screw rod, the screw rod is sleeved with a spring and then penetrates through the machine frame, the tail end of the screw rod is sleeved with a sensing nut, and a sensor is arranged under the sensing nut and on the machine frame.
Description
Technical field
The utility model relates to a kind of chain type transporter means field, is specially a kind of chain tension degree testing fixture.
Background technology
Apron conveyer is a kind of equipment that can realize the material automatic transportation, the warping strength fatigue that it has, and shock resistance is good, and transport capacity is large, starts steadily, and the advantages such as safety make it be widely used in commercial production, the fields such as logistics transportation.In the conveyer the inside by chain-driving such as apron conveyer, chain converyer, because chain length is longer, and own wt is larger, when installing, chain needs tensioning, and chain is through after the regular hour operation, drawing, normal wearing and tearing can make chain that certain amount of tension is arranged, and cause chain sag to increase gradually, and the degree of tension of chain is inadequate like this, chain produces acutely beats, loose chain occurs easily, run the phenomenons such as chain, chain jamming, chain rupture, not only can damage equipment, also consist of potential safety hazard simultaneously.
Summary of the invention
For the defects of prior art, the utility model is carried and has been encircleed a kind of chain tension degree testing fixture, and it can the adjusting chain degree of tension, and actv. has avoided chain to take off chain, has prolonged service life of equipment.
The technical solution of the utility model is: it comprises frame and sprocket wheel, described sprocket wheel and chain engaged transmission, be fixed with carrier bar on the described chain, it is characterized in that: be provided with slide rail on the described frame, the wheel shaft of sprocket wheel is installed on slide block, described slide block is installed on slide rail, described slide block connecting screw rod passes frame behind the described screw sleeve shock mount, and its end is set with the induction nut, below described induction nut, on the described frame sensor is installed.
After adopting design of the present utility model, after stretching appearred in the chain of apron conveyer, spring can be passed screw rod, sprocket wheel simultaneously outward, to guarantee the chain tension degree.When chain stretches the amount that reaches certain, the induction nut proximity transducer position on the screw rod, sensor sensing can send alerting signal to behind the induction nut, reminds adjusting chain.Such design can effectively solve the problem that chain takes off chain, has prolonged service life of equipment, has avoided potential safety hazard.
Description of drawings
Fig. 1 is the part sectional view of the utility model front view.
The specific embodiment
Embodiment is described in further detail the utility model below in conjunction with accompanying drawing.
See Fig. 1, the utility model comprises frame 1 and sprocket wheel 2, be provided with slide rail 3 on the frame 1, the wheel shaft of sprocket wheel 2 is installed on slide block 4, and slide block 4 is installed on slide rail 3, slide block 4 connecting screw rods 6, pass frame 1 behind screw rod 6 pocketed springs 7, its end is set with induction nut 8, below induction nut 8, sensor 9 is installed on the frame 1.
In case after stretching appearred in the chain 5 of apron conveyer, spring 7 can be passed screw rod 6, sprocket wheel 2 simultaneously outward, to guarantee chain 5 degree of tensions.When chain 5 stretched the amount that reaches certain, during induction nut 8 proximity transducers 9 position on the screw rod 6, sensor 9 can send alerting signal after sensing approaching of induction nut 8, reminds adjusting chain 5.Such design can effectively avoid chain to take off the problem of chain, has prolonged service life of equipment, has avoided potential safety hazard.
