Detailed description of the invention
By reference to the accompanying drawings the utility model is described in further detail below by specific embodiment.
Consider and the problem that the tension structure area occupied of current band conveyor is large provide a kind of cylinder tension structure in the utility model embodiment.
This cylinder tension structure comprises: the first leading screw, the two ends of described first leading screw arrange direction reverser respectively, two described direction reversers are connected with corresponding crank respectively by the transmission device of correspondence, and two described cranks are fixedly connected with one end of the externally positioned type bearing of cylinder respectively.
Described direction reverser comprises ramp structure and gear, described first leading screw passes described ramp structure and is threaded, and is acute angle with the angle on the inclined-plane of described ramp structure, and described inclined-plane is provided with tooth bar, described tooth bar is vertical with described first leading screw, and described gear and described tooth bar are meshed.
After operating the first screw turns, because commutating structure is connected with the first threads of lead screw, commutating structure changes rotation into straight-line motion, and straight-line motion is delivered to crank through transmission device, and crank head roll rotates, and reaches the effect of tensioning.In real work, rotate the first leading screw as required, then through direction reverser, be transformed into straight-line motion up or down, then carry out being transferred to crank, crank handle turns cylinder does conter clockwise or rotates clockwise, and carries out belt tension.In this cylinder tension structure, crank is connected with the outboard bearing of cylinder, and relative position relation, the annexation of the first leading screw, direction reverser, transmission device, crank are all comparatively simple, and assembly is few, and be in the below of cylinder, area occupied is less.
Below, be described in detail this cylinder tension structure, as illustrated in fig. 1 and 2, a kind of cylinder tension structure, comprising: the first leading screw 1, direction reverser, transmission device, crank 12, cylinder 11; Wherein, the first leading screw 1 is a long screw, and be positioned at the below of cylinder 11, long screw is furnished with turning handle, and this turning handle can drive the first leading screw 1 to rotate.The two ends of the first leading screw 1 are installed with ramp structure 2, this ramp structure 2 inside is provided with tapped through hole, first leading screw 1 is threaded with this tapped through hole, the inclined-plane of this ramp structure 2 is provided with tooth bar, this tooth bar is vertical with the first leading screw 1, rack and pinion 3 engages, and gear 3 and ramp structure 2 form direction reverser, and the rotation of the first leading screw 1 is converted to the straight-line motion perpendicular to the first leading screw 1 by this commutating structure.Gear 3 is installed on gear stand 14, and gear stand 14 carries out straight-line motion with gear 3.
Transmission device can do straight-line motion with gear stand 14, and transmits this straight-line motion.In order to the straight-line motion after commutating carries out actv. transmission, first the present embodiment devises the most basic screw mandrel 5, silk 13 and crank 12, concrete annexation is: screw mandrel 5 and gear stand 14 are fixedly linked, screw mandrel is connected with crank 12 by silk 13 again, namely one end of screw mandrel 5 is connected with gear stand 14, the other end is connected with the tapped bore of silk 13 one end, and the pin-and-hole of silk 13 other end and the connecting bore of crank 12 are linked together by bearing pin 6.
Because gear stand 14 is fixedly connected with screw mandrel 5, so many connection modes all can adopt, such as weld or be threaded.
In concrete tensioning process, in order to avoid screw mandrel double swerve, devise support 14 in the present embodiment, support 14 arranges through hole, the other end that support 14 is relative with through hole is connected on fixed pan.Screw mandrel, can only straight-line motion through through hole, can not double swerve.
Simultaneously, can be there is upper and lower straight-line motion in screw mandrel in tensioning process, in order to carry out reset processing to screw mandrel, devise spring 4 in this embodiment, one end of spring 4 contacts with gear stand 14 and connects, and the other end is fixedly connected with this support 14 (weld or be fixedly connected with by spring perch).When screw mandrel does straight-line motion, spring 4 is elongated, and can produce reset force.
Because crank 12 drives cylinder 11 to rotate, so adopt silk 13 to be connected in the present embodiment between screw mandrel and crank 12, and silk adopts bearing pin 6 to connect between 13 and crank 12, and then produces and be rotationally connected flexibly.
The two ends of the external bearing 8 of cylinder 11 are all fixedly connected with a crank 12 mentioned above, and then drive cylinder 11 to rotate when crank 12 above moves, cylinder 11 scrolling load-transfer device, and then reach the object of Conveyer Belt.
Embodiment 2:
The present embodiment does slight change on the basis of embodiment 1, and the screw mandrel of embodiment 1 can replace with push rod, and one end of push rod connecting filament head arranges screw thread.If by hand reset, spring can be cancelled.
In real work, rotate the first leading screw as required, then through direction reverser, be transformed into straight-line motion up or down, then carry out being transferred to crank, crank handle turns cylinder does conter clockwise or rotates clockwise, and carries out belt tension.In this cylinder tension structure, crank is connected with the outboard bearing of cylinder, and relative position relation, the annexation of the first leading screw, direction reverser, transmission device, crank are all comparatively simple, and area occupied is less.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
