Abstract
The invention relates to a screw type tensioner. An adjusting screw rod is in threaded connection onto a mounting plate, one end of the adjusting screw rod is fixed on a driven seat in a rotating mode, and a rotating handle is arranged at the other end of the adjusting screw rod; a pressure spring is positioned between the driven seat and the mounting plate on the adjusting screw rod. The adjusting screw rod is driven to rotate through the rotating handle; due to the fact that one end of the adjusting screw rod is fixed on the driven seat in the rotating mode, the adjusting screw rod can telescope on the mounting plate after autorotation, the driven seat is driven to move on the sliding rail of the driven seat, and an effect of tensioning a conveyor belt is achieved. Moreover, the pressure spring is positioned between the driven seat and the mounting plate on the adjusting screw rod; through the effect of the pressure spring, inverted elastic force can be provided during tensioning, so that the rotating load of an operator is increased to achieve the purposes of warning and protecting the conveyor belt, and the service life can be prevented from being shortened by excessive tensioning of the conveyor belt.
Description
Technical field
The present invention relates to a kind of device of the tension force for changing belt, rope or chain, being specifically related to a kind of screw tension device.
Background technology
The effect of tightening device makes load-transfer device obtain necessary tension force, in order to avoid adhesive tape skids on cylinder, and reduces the sag of load-transfer device between two groups of carrying rollers, reduce the vibration of belt conveyor.Tightening device is normally contained in one end of follower rollers.Screw tension utensil conventional at present has structure simple, compact, advantage easy for installation, but needs artificial adjustment, and tensile force can not keep constant.Be generally used for length and be less than 80m, and on lower-powered conveyer.
Summary of the invention
The object of the present invention is to provide a kind of screw tension device, can with keeping constant tensile force to load-transfer device on a conveyor.
For achieving the above object, technical scheme of the present invention is: screw tension device, comprise support, described support is provided with follower rollers, the rotating shaft of described follower rollers is fixed on driven seat, described support is provided with driven seat slide rail, described driven seat slide rail comprises upper and lower two slideways, vertical adapter plate is fixed with between described upper and lower two slideways, described adapter plate has been threaded adjusting screw(rod), one end of described adjusting screw(rod) is rotated and is fixed on driven seat, and the described adjusting screw(rod) other end is provided with turning handle; Described adjusting screw(rod) is provided with stage clip between driven seat and adapter plate.
When adopting technique scheme, drive adjusting screw(rod) to rotate by turning handle, the one end due to adjusting screw(rod) rotates to be fixed on driven seat, can stretch on a mounting board after adjusting screw(rod) rotation, thus drive driven seat to move on driven seat slide rail, thus play the effect of tensioning belt conveyor.In addition, adjusting screw(rod) is provided with stage clip between driven seat and adapter plate, by the effect of stage clip; reverse elastic force can be provided when tensioning; increase the rotating load of operator, play the object of warning and protection belt conveyor, belt conveyor transition tensioning can be avoided to cause the shortening in service life.
Further, described driven seat slide rail is provided with limiting stopper.Above-mentioned design can play spacing effect, the amplitude that restriction regulates.
Further, described frame bottom is provided with the projection protruded downwards, and described support installing is on bearing, and described bearing is provided with chute, and described projection inserts in chute, and described bearing is provided with the bolt of lock bracket.Above-mentioned relating to, can regulate length and location according to the actual conditions of belt conveyor, is also the scope adding adjustment from another thinking and structure.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation:
Fig. 1 is the structural representation of screw tension device embodiment of the present invention.
Detailed description of the invention
As shown in Figure 1, screw tension device of the present invention, comprises support, and support is connected to follower rollers 2 by bearing, around belt conveyor 1 on follower rollers 2.The rotating shaft of follower rollers 2 is fixed on driven seat 21, and support is provided with driven seat slide rail 22, and driven seat slide rail 22 includes upper and lower two slideways, and be fixed with vertical adapter plate 3 between upper and lower two slideways, adapter plate 3 has been threaded adjusting screw(rod) 4.One end of adjusting screw(rod) 4 is rotated and is fixed on driven seat, and adjusting screw(rod) 4 other end is provided with turning handle; Adjusting screw(rod) 4 is provided with stage clip (not shown) between driven seat and adapter plate.Driven seat slide rail 22 is provided with limiting stopper.Above-mentioned design can play spacing effect, the amplitude that restriction regulates.Described frame bottom is provided with the projection protruded downwards, and described support installing is on bearing, and described bearing is provided with chute, and described projection inserts in chute, and described bearing is provided with the bolt of lock bracket.Above-mentioned relating to, can regulate length and location according to the actual conditions of belt conveyor 1, is also the scope adding adjustment from another thinking and structure.
Adjusting screw(rod) 4 is driven to rotate by turning handle, one end due to adjusting screw(rod) 4 rotates to be fixed on driven seat 21, can be flexible on adapter plate 3 after adjusting screw(rod) 4 rotation, thus drive driven seat 21 to move on driven seat slide rail 22, thus play the effect of tensioning belt conveyor 1.In addition; adjusting screw(rod) 4 is provided with stage clip between driven seat 21 and adapter plate 3; by the effect of stage clip; reverse elastic force can be provided when tensioning; increase the rotating load of operator; play the object of warning and protection belt conveyor 1, belt conveyor 1 transition tensioning can be avoided to cause the shortening in service life.
Above-described is only the preferred embodiment of the present invention; should be understood that; for a person skilled in the art; without departing from the inventive concept of the premise; some distortion and improvement can also be made; these also should be considered as protection scope of the present invention, and these all can not affect effect of the invention process and practical applicability.
