Abstract
The utility model relates to a high-tension tail tension device for a belt conveyor, which comprises lead screws, nuts, bearing blocks, tail tension drums and a tailstock, wherein the tail tension drums are arranged on the tailstock, two ends of a drum shaft of each tail tension drum are arranged in the corresponding bearing blocks, the lead screws are connected with the bearing blocks, and the nuts matched with the lead screws are fixed onto vertical columns of the tailstock. The high-tension tail tension device is characterized in that the bearing blocks are square bearing blocks, an upper convex slide way and a lower convex slide way are arranged on the tailstock, the square bearing blocks are arranged in the upper convex slide way and the lower convex slide way and in slide connection with the same, the square bearing blocks are provided with grooves matched with projecting blocks of the upper convex slide way and the lower convex slide way, and the lead screws are in threaded connection with the square bearing blocks. The high-tension tail tension device for the belt conveyor has the advantages that the device is reasonable in design, the problem of severe wear of original lead screws and common bearing blocks is solved, the bearing blocks are good in positioning effect by the aid of the upper convex slide way and the lower convex slide way, operation is stable and reliable, the failure rate of the device is effectively decreased, and operating rate of a belt conveyor system is increased.
Description
Technical field
The utility model belongs to the belt conveyor slack adjuster technical field, relates in particular to a kind of sealing-tape machine hightension afterbody take-up device.
Background technology
In technique known, " figure number of Transport Machinery design Selection handbook is the afterbody take-up device that DT II 0XJ02XX1 discloses a kind of belt conveyer, and this device is to form the afterbody take-up device with leading screw and screw pulling plain shaft bearing at present; This device is because the bearing seat of cylinder adopts is the plain shaft bearing, so the tension leading screw can only spur the bottom of bearing seat, tension leading screw and drum shaft be not on a horizontal surface; The moment of torsion that forms makes bearing seat and the other strength of tension leading screw; Serious wear, the life-span is short, and whole plain shaft bearing translation in the groove of tailstock in this device; Because locating effect is bad; It is not steady that the plain shaft bearing is moved, and causes fault rate higher, and then reduced the operating rate of belt conveyor system.
The afterbody take-up device of another kind of known belt conveyer is to adopt two hydraulic actuating cylinder pulling plain shaft bearings to form the afterbody take-up device, and this device can not effectively be adjusted rubber belt from deviating because the tensioning pulling force can not be strained separately; Hydraulic pressure tension investment is high; Running cost and fault rate are higher; The bearing seat of this device also is the plain shaft bearing, and also not on a horizontal surface, the moment of torsion of formation makes bearing seat and tension leading screw serious wear life-span short for tension leading screw and drum shaft; Running cost and fault rate are higher, have reduced the operating rate of belt conveyor system.
More than the common afterbody take-up device tensioning pulling force of two kinds of known belt conveyers little, the serious wear life-span is short, running cost and fault rate are higher, have reduced the operating rate of belt conveyor system.
Summary of the invention
The purpose of the utility model provides a kind of sealing-tape machine hightension afterbody take-up device, and this apparatus structure is simple, and is reasonable in design, long service life, and field of application is wider, and then has improved the operating rate of belt conveyor system.
For realizing above-mentioned purpose, the utility model is realized through following technical scheme:
Sealing-tape machine hightension afterbody take-up device comprises leading screw, screw, bearing seat, afterbody tension drum, tailstock, and tailstock is provided with the afterbody tension drum; The drum shaft two ends of afterbody tension drum are arranged in the bearing seat, and leading screw is connected with bearing seat, and the screw that cooperates with leading screw is fixed on the column of tailstock; It is characterized in that; Described bearing seat is the square shaft bearing, and tailstock is provided with up and down convex slideway, and the square shaft bearing is arranged on up and down in the convex slideway; And with convex slideway sliding block joint up and down.
Described square shaft bearing is provided with the groove that matches with the protruding block of convex slideway up and down.
Described leading screw adopts with the square shaft bearing and is threaded.
Compared with prior art, the beneficial effect of the utility model is:
1) this device adopts the square shaft bearing to be connected with leading screw; Make the connection location of leading screw and square shaft bearing can directly be positioned on the plane, drum shaft place; And then the pulling force moment of torsion that leading screw acts on the square shaft bearing is zero; Reasonable in design, solved the problem of original leading screw and plain shaft bearing serious wear, safe and reliable;
2) the square shaft bearing of this device is arranged on up and down in the convex slideway; And the square shaft bearing is provided with the groove that matches with the protruding block of convex slideway up and down; Make square shaft bearing good positioning effect; It is reliable to operate steadily, and has effectively reduced the fault rate of this device, and then has improved the operating rate of sealing-tape machine system.
This device is low with respect to hydraulic pressure tension cost of investment, and running cost and fault rate are lower, and be safe and reliable, makes the afterbody take-up device field of application of belt conveyer wider, long service life.

The specific embodiment
Describe in further detail below in conjunction with the specific embodiment of accompanying drawing the utility model.
Embodiment one, sees Fig. 1, Fig. 2, sealing-tape machine hightension afterbody take-up device; Comprise leading screw 1, screw 2, bearing seat, afterbody tension drum 6, tailstock 5, tailstock 5 is provided with afterbody tension drum 6, and the drum shaft two ends of afterbody tension drum 6 are arranged in the bearing seat; The specification of leading screw 1 is M50; Leading screw 1 is connected with bearing seat, and the screw 2 that cooperates with leading screw 1 is fixed on the column of tailstock 5, it is characterized in that described bearing seat is a square shaft bearing 4; Tailstock 5 is provided with up and down convex slideway 3, and square shaft bearing 4 is arranged on up and down in the convex slideway 3; And with convex slideway 3 sliding block joints up and down, described square shaft bearing 4 is provided with the groove that matches with the protruding block of convex slideway 3 up and down, and leading screw 1 adopts with square shaft bearing 4 and is threaded, and convex slideway 3 adopts shaped steel to process up and down.
When using this device to carry out the operation of tensioning sealing-tape machine; At first through the relative rotation of leading screw 1 with screw 2; Leading screw 1 is produced to be moved axially; Two the square shaft bearings 4 of drive that move synchronously of two leading screws 1 are being slided in the convex slideway 3 up and down, and then pulling afterbody tension drum 6, and the mobile adhesive tape 7 that makes of afterbody tension drum 6 is realized tensioning adjustment.
