Description
Technical field
The utility model relates to the lift accessory, is specially the large-scale hoister belt from tension device.
Background technique
Present grain reserves warehouse and rice processing enterprises, the large-scale large output lift that is equipped with, model specification is various.After the new equipment Installation and Debugging were put into production, few people went to check the elasticity of adjusting belt again.The lift running is run the limit and is skidded, and Nobody Knows.
Summary of the invention
The technical problem that the utility model solves is to provide the large-scale hoister belt from tension device, to solve the shortcoming in the above-mentioned background technology.
The technical problem that the utility model solves realizes by the following technical solutions:
The large-scale hoister belt is from tension device, comprise support, regulate screw mandrel, outer sleeve, spring, inner sleeve, bearing slip tooth plate, ratchet and press strip, the top of described support is equipped with the adjusting screw mandrel, described adjusting screw mandrel bottom is equipped with spring, described spring outside is equipped with outer sleeve, the underpart of described adjusting screw mandrel is equipped with inner sleeve, described adjusting screw mandrel bottom is bearing, be provided with bearing slip tooth plate on bearing, described bearing slip tooth plate bottom is equipped with ratchet, and the bearing outside is equipped with press strip.
Beneficial effect: the utility model is simple in structure, and is easy to use.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is another structural representation of the present utility model.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
referring to Fig. 1, the large-scale hoister belt is from the structural representation of tension device, the large-scale hoister belt is from another structural representation of tension device, the large-scale hoister belt is from tension device, comprise support 1, regulate screw mandrel 2, outer sleeve 3, spring 4, inner sleeve 5, bearing slip tooth plate 6, ratchet 7 and press strip 8, the top of described support 1 is equipped with regulates screw mandrel 2, described adjusting screw mandrel 2 bottoms are equipped with spring 4, described spring 4 outsides are equipped with outer sleeve 3, the underpart of described adjusting screw mandrel 2 is equipped with inner sleeve 5, described adjusting screw mandrel 2 bottoms are bearing, be provided with bearing slip tooth plate 6 on bearing, described bearing slip tooth plate 6 bottoms are equipped with ratchet 7, the bearing outside is equipped with press strip 8.
Adopt the deadweight and the tension force that adds spring of support return pulley, in case the belt for lifting machine operating time is oversize, belt is futile lax, the bearing slip tooth plate of support, deadweight and the tension force that adds spring due to return pulley, the ratchet on return pulley sinking drive slip tooth plate both sides is adjusted tooth pitch automatically, belt is auto-tensioning thereupon, if belt has the limit of race phenomenon, can adopt the screw mandrel on manual tune both sides, till adjusting to optimum, thereby prevent that effectively belt from running the limit, the phenomenon such as skid occurs, and guarantees the normal operation of equipment.
The new lift of installing, at first with support from tension device both sides ratchet pull-up, regulate screw mandrel and up transfer to highest point, Compress Spring returns to highest point, belt is tightened up, and opening device dallies, and adjusts the adjusting screw mandrel on both sides, after belt works well, fall the both sides ratchet, can enter normal operation.
above demonstration and described basic principle of the present utility model and major character and advantage of the present utility model, the technician of the industry should understand, the utility model is not restricted to the described embodiments, that describes in above-described embodiment and specification just illustrates principle of the present utility model, under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications, these changes and improvements all fall in claimed the utility model scope, the claimed scope of the utility model is defined by appending claims and equivalent thereof.
