Abstract
The utility model relates to a middle spiral tension device of a reversible belt conveyor. The middle spiral tension device comprises a support which is fixedly arranged, and a screw with one end fixed to the support. Guide rails which are fixedly arranged are arranged in the middle of the support. Bend rollers are arranged on the two sides of the support respectively. Lifting devices which can rise and fall along the guide rails in the vertical direction are arranged on the path of the screw. Each lifting device is provided with a tension roller corresponding to the corresponding bend roller, and conveyor belts are arranged on the tension rollers and the bend rollers in a penetrating mode. The middle spiral tension device has the advantages that the structure is simple and compact, the conveyor belts can have enough tension, the sag of the conveyor belts between all the rollers is limited, it is ensured that enough friction is generated between the conveyor belts and transmission rollers so that the conveyor belts can not slip, normal running of the reversible belt conveyor is ensured, space is saved, flexibility is high, installation and detachment can be conveniently conducted, time is saved, the basic requirement is simple, the operation is convenient, safe and reliable, and the requirement for product serialization can be easily met.
Description
technical field:
The utility model relates to belt conveyer field, and concrete is a kind of reversible belt conveyer intermediate conveyor screw take-up device.
technical background:
Belt conveyer is widely used in the industries such as metallurgy, coal, electric power, building materials, chemical industry, traffic, light industry.And take-up device is one of vitals of belt conveyer, radical function is to make load-transfer device have enough tension force, guarantee that between load-transfer device and driving drum, producing enough friction force makes load-transfer device non-slip, and the sag of limit transport band between each carrying roller, belt conveyer is normally moved.For the reversible belt conveyer of part, because all need end to end discharging, limited space, common tension mode inconvenience is used, the middle take-up device conventionally adopting, but in the middle of existing, take-up device takes up room greatly, and dismounting is inconvenient, very flexible, cost is high.
utility model content:
The purpose of this utility model is to provide a kind of reversible belt conveyer intermediate conveyor screw take-up device, and it can solve reversible belt conveyer because all needing end to end discharging, limited space, the problem that common tension mode cannot meet the demands.It is not only simple and compact for structure, easy installation and removal, and easily meet product seriation requirement.
The technical solution adopted in the utility model is for this reason: the utility model comprises that support and one end of setting firmly are fixed on the screw rod on support, in the middle of support, is provided with hard-wired guide rail, and support both sides are respectively equipped with bend pulley; The path of screw rod is provided with the jacking system that can move up and down up and down along guide rail, and each jacking system is provided with the tension drum corresponding with described bend pulley, on tension drum, bend pulley, wears load-transfer device.
Described jacking system is rolling bearing units, and described tension drum is arranged on screw rod by rolling bearing units.
The utility model has the advantages that: simple and compact for structure, can make load-transfer device produce enough tension force, the sag of limit transport band between each carrying roller, and guarantee that between load-transfer device and driving drum, producing enough friction force makes load-transfer device non-slip, guarantee that reversible belt conveyer normally moves, save space, alerting ability is good, is easy for installation and removal, saves time, and basis requires simple, easy to operate, safe and reliable, easily meet product seriation requirement.
accompanying drawing explanation:
Fig. 1 is front view of the present utility model;
Fig. 2 is left view of the present utility model;
Fig. 3 is birds-eye view of the present utility model.
In figure 1 for tension support, 2 be nut, 3 for screw rod, 4 for guide rail, 5 for bend pulley, 6 for middle frame, 7 for back-up ring, 8 for screw, 9 for rolling bearing units, 10 for tension drum, 11 for sole, 12 be load-transfer device.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is made to specific description, to being better understood:
Reversible belt conveyer intermediate conveyor screw take-up device, comprise tension support 1 and screw rod 3, described tension support 1 upper end is fixed on middle frame 6 with fastener, and lower end footing piece 11 directly welds with built-in fitting, and left and right two ends are all provided with bend pulley 5 in fastener mode; In the middle of described tension support 1, there is hard-wired guide rail 4; Described screw rod 3 one end are connected in screw thread pair mode with the nut 2 being welded on tension support 1, and the other end is rotationally connected in back-up ring 7 screw 8 modes with rolling bearing units 9 fixing and that can only move up and down along the guide rail 4 on tension support 1; On described rolling bearing units 9, tension drum 10 is installed; On described each tension drum 10, bend pulley 5 through there being load-transfer device 12 turn screw rods 3 to drive rolling bearing units 9 and tension drum 10 mounted thereto to move up and down the tensioning that realizes load-transfer device 12 along guide rail 4.
