Abstract
The utility model discloses a kind of spiral tensioning devices of locking bar, balladeur train is provided on tailstock and has been bolted spiral tensioning device, the rear end of spiral tensioning device after check lock lever Screw assembly and with tailstock with being screwed, bend pulley has been fastened by bolts on spiral tensioning device, in L band hook-types, the locking hole of the other end across the locking screw processing of operating lever, which inside and outside reveals and passes through pin card, to be prevented for one end of operating lever.Tailstock is welded or is threadedly coupled with conveying steel structure base built-in fitting.Locking hole is adjacent to be processed and is mutually perpendicular to.The other end of operating lever is assemblied in being locked into hole and rotating 180 ° for locking screw.The technical program is skillfully constructed, it is simple to operate, it only needs simply realize very much that the tail portion bend pulley of conveyer is adjusted by operating lever operation, normal operation for conveyer belt provides tensile force, and transport belt slippery caused by preventing stripped thread, it is effectively guaranteed the safe and reliable work of conveyer.
Description
Technical field
The utility model is related to a kind of spiral tensioning device of locking bar, especially suitable for being used on ribbon conveyer.
Background technology
Ribbon conveyer is a kind of widely used material transfer equipment, in metallurgy, coal, light industry, grain, electric power, is built
The industries such as material and traffic and transportation sector largely use.It is mainly by rack, driving device, roller, carrying roller, adhesive tape, tension device
And the compositions such as safety guard.Wherein, the main function of tension device is that adhesive tape is made to have enough tension, ensures conveying
Enough frictional force is generated between band and driving drum, makes adhesive tape non-slip, and limits sag of the adhesive tape between each carrying roller, makes belt
Conveyer normal operation.
In light-duty, short distance ribbon conveyer, tension device is substantially all using spiral tensioning device.In belt conveying
Machine initial launch after adhesive tape generates flexible deformation and replaces virgin rubber band in operational process, is required for the tension progress to adhesive tape
Adjustment, the means of adjustment are exactly to achieve the purpose that adjust tension to tense stern roll by rotating trapezoidal screw.In operation
Adhesive tape, stern roll etc. are rotating always, can generate shake, since spiral tensioning device does not have a locking device, when there is stripped thread to show
As occurring, conveyor belt tension is caused to decline, so as to cause failures such as rubber belt from deviating, roller skiddings.
Invention content
The task of the utility model is to propose that one kind does not increase cost, increases self locking while keeping and tensing, and
A kind of spiral tensioning device of easy to operate locking bar.
The task of the utility model is done in such a way that it includes tailstock, bend pulley and adhesive tape, it is characterised in that：Tail
Balladeur train is provided on frame and has been bolted spiral tensioning device, rear end and the check lock lever screw thread of the spiral tensioning device
It is screwed after assembling and with tailstock, bend pulley has been fastened by bolts on spiral tensioning device, the end of locking screw adds
Work has two locking holes, and in L band hook-types, the other end of the operating lever passes through the locking of locking screw processing for one end of operating lever
Hole, which inside and outside reveals and passes through pin card, prevents.Tailstock is welded or is threadedly coupled with conveying steel structure base built-in fitting.The locking hole phase
Neighbour processes and is mutually perpendicular to.The other end of the operating lever is assemblied in being locked into hole and rotating 180 ° for locking screw.
The utility model has the following effects that：The technical program is skillfully constructed, and production and processing difficulty is low, side easy to operate
Just, it is only necessary to which the tail portion bend pulley that can simply realize very much conveyer by operating lever operation is adjusted, and is conveyer belt
Normal operation provides tensile force, and transport belt slippery caused by preventing stripped thread, is effectively guaranteed the safe and reliable work of conveyer
Make.
Description of the drawings
Fig. 1 is that the structure of locking screw disconnects schematic diagram；Fig. 2 is tension device adjustment structure schematic diagram；Fig. 3 is conveyer
Structure diagram during work.
Drawing explanation：1st, tailstock, 2, locking screw, 3, operating lever, 4, spiral tensioning device, 5, bend pulley, 6, adhesive tape.
Specific embodiment
Embodiment is described in detail with reference to the figures above, as depicted in figs. 1 and 2, tailstock 1 and conveying steel structure base built-in fitting
Welding is threadedly coupled, balladeur train is provided on the tailstock and has been bolted spiral tensioning device 4, the spiral fastening
The rear end of device has been fastened by bolts with being screwed after 2 Screw assembly of locking screw and with tailstock 1 on spiral tensioning device
Bend pulley 5, the end machining of the locking screw have two locking holes, and the locking hole is adjacent to be processed and be mutually perpendicular to,
One end of operating lever 3 passes through the locking hole of locking screw processing inside and outside to reveal and lead in L band hook-types, the other end of the operating lever 3
It crosses pin card to prevent, prevents operating lever from coming off, adhesive tape 6 is wound on the bend pulley 5, it can moving forward and backward with bend pulley
Carry out the tension of belt.
The other end of the operating lever is assemblied in being locked into hole and rotating 180 ° for locking screw.
Angle steel is provided on the tailstock, when belt tension meets operation demand, the crotch on operating lever top is towards tail
Frame direction is hooked in above 1 angle steel of tailstock.
During work, when needing to be adjusted adhesive tape 6 elastic, hand is held operating lever 3 and is carried upwards, steps part tailstock angle
After rotating 180 ° after steel, operating lever can replace spanner rotation lock screw 2 at this time, and dragging bend pulley 5 adjusts adhesive tape 6 to reach
Purpose.Operating lever 3 is kept in the center after having adjusted.When in conveyer normal course of operation, belt tension meets operation demand
When, 3 top crotch part of operating lever is hooked in above 1 angle steel of tailstock, is trembled when locking screw 2 is redirected roller 5 towards 1 direction of tailstock
When dynamic to be rotated, 3 top crotch of operating lever is stuck and prevents locking screw 2 from rotating, and can effectively ensure conveying equipment just
Often operation.
