Abstract
The invention discloses a spring type tension roller which comprises a base, two support pillars and a tension roller main body which are fixed on the base, wherein the tension roller main body is fixed between two support pillars through lower bolsters which are arranged on the support pillars and have adjustable upper location and lower position, an upper bolster is arranged on the upper end of each support pillar, and springs are arranged between the upper bolsters and the lower bolsters. The spring type tension roller can be used for solving the problems of low accuracy and fussy operation of adjusting the tension of the tension roller in the prior art, and can realize the regulation of the tension of the tension roller through adjusting the elasticity of the springs arranged on two sides of the tension roller main body and a spring limit piece; and compared with the traditional tension wheel, the spring type tension roller has the advantages of higher adjusting accuracy, simplicity in operation, and easiness for realization.
Description
Technical field
The present invention relates to a kind of spring loaded expansion tightening wheel, belonged to the elevator technology field.
Background technology
Expansion tightening wheel can be different according to belt tightness, automatically adjust tensile force, make the driving system stability and safety reliable.Traditional expansion tightening wheel normally adopts gravity tensioner system, when steel rope is elongated under Action of Gravity Field, need to change the expanding force of expansion tightening wheel by adjusting gravity, but this adjustment mode is not only adjusted precision and can't be guaranteed, and when operation is more loaded down with trivial details.
Summary of the invention
Technical matters to be solved by this invention provides a kind of spring loaded expansion tightening wheel, and the adjustment to expansion tightening wheel tension force can be realized in the elastic force by adjusting spring and the position of limit switch, and simple to operate, precision is controlled.
In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is:
A kind of spring loaded expansion tightening wheel, comprise base, be fixed on two pillar stiffeners and expansion tightening wheel main body on the described base, described expansion tightening wheel main body is fixed between described two pillar stiffeners by being installed in lower bolster on the described pillar stiffener, that upper-lower position is adjustable, the upper end of described pillar stiffener also is equipped with upper padding plate, between described upper padding plate and the lower bolster spring is installed.
Aforesaid spring loaded expansion tightening wheel is characterized in that: described upper padding plate is adjustable with respect to the pillar stiffener upper-lower position.
Aforesaid spring loaded expansion tightening wheel is characterized in that: the lower limit part for control lower bolster position is installed on the pillar stiffener of described lower bolster below, the upper limit spare for control upper padding plate position is installed on the pillar stiffener of described upper padding plate top.
Aforesaid spring loaded expansion tightening wheel is characterized in that: upper padding plate and the lower bolster among of described expansion tightening wheel main body both sides are equipped with two springs.
The invention has the beneficial effects as follows: the elastic force of the spring by adjusting expansion tightening wheel main body both sides and spring limiting part can be realized the adjustment to expansion tightening wheel tension force, with respect to traditional expansion tightening wheel, adjust precision higher, and operation are relatively simple, are easier to realize.
Description of drawings
Fig. 1 is the lateral plan of spring loaded expansion tightening wheel of the present invention;
Fig. 2 is the front elevation of spring loaded expansion tightening wheel of the present invention.
The specific embodiment
Below in conjunction with Figure of description, the present invention is further illustrated.
As depicted in figs. 1 and 2, a kind of spring loaded expansion tightening wheel, comprise base 1, be fixed on two pillar stiffeners 2 and expansion tightening wheel main body 3 on the base 1, expansion tightening wheel main body 3 is by being installed on the pillar stiffener 2, the lower bolster 4 that upper-lower position is adjustable is fixed between described two pillar stiffeners 2, the upper end of pillar stiffener 2 also is equipped with upper padding plate 6, between upper padding plate 6 and the lower bolster 4 spring 5 is installed, upper padding plate 6 is adjustable with respect to pillar stiffener 2 upper-lower positions, lower limit part 7 for control lower bolster 4 positions is installed on the pillar stiffener 2 of lower bolster 4 belows, the upper limit spare 8 for control upper padding plate 6 positions is installed on the pillar stiffener 2 of upper padding plate 6 tops.
By adjusting the upper-lower position of lower limit part 7, realization is to the adjustment of lower bolster 4 positions, realization is to the upper-lower position of expansion tightening wheel main body 3 with to the adjustment of spring 5 elastic force, namely realized the adjustment to its tension force, by adjusting the upper-lower position of upper limit spare 8, having realized the adjustment to upper padding plate 6 positions, realized the adjustment to spring 5 elastic force, also is the adjustment that realizes expansion tightening wheel main body 3 tension force.
Upper padding plate 6 and lower bolster 4 amongs of expansion tightening wheel main body 3 both sides are equipped with two springs 5, and the elastic force of spring 5 is evenly distributed between the lower bolster, are convenient to control the tension force of expansion tightening wheel main body 3.
In sum, a kind of spring loaded expansion tightening wheel provided by the invention, the adjustment to expansion tightening wheel tension force can be realized in the elastic force by adjusting spring and the position of limit switch, simple to operate, precision is controlled.
Above demonstration and described groundwork of the present invention, principal character and advantage.The technical personnel of the industry should be understood; the present invention is not restricted to the described embodiments; that describes in above-described embodiment and the specification sheets just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is by appending claims and equivalent circle thereof.
