Fig. 1 to Fig. 4 is please referred to, a kind of strainer 100 is present embodiments provided, comprising:
Mounting base, mounting base include pedestal 11 and fixed part 13, and fixed part 13 is connected to pedestal 11, and pedestal 11 is used for and skin
The motor mounting plate 200 of translator connects；
Stretching unit, stretching unit include rocker arm 31 and pressing piece 33, and one end of rocker arm 31 is connect with pressing piece 33, rocker arm
31 other end and pedestal 11 is hinged, and pressing piece 33 with chain 101 to be tensioned for contacting；
The part of pretightning force part 50, the separate pedestal 11 of one end and rocker arm 31 of pretightning force part 50 is connect, pretightning force part 50
Other end connect with fixed part 13, pretightning force part 50 has the part of the separate pedestal 11 of rocker arm 31 to fixed part 13
Close trend and pressing piece 33 is made to press chain 101.
Specifically, pressing piece 33 includes connecting shaft 332 and pressing roller 334, pressing roller 334 is rotationally sheathed on connecting shaft
332, for contacting with chain 101 to be tensioned, one end of connecting shaft 332 is fixedly connected pressing roller 334 with rocker arm 31.
In the present embodiment, the quantity of stretching unit is two, and two stretching units have the cooperation of pretightning force part 50.
Detailed, the pressing piece 33 of two stretching units treats tension chain under the action of respective pretightning force part 50
101 pressings, and the direction pressed is opposite.As shown in the figure, two pressing pieces 33 be under the active force of pretightning force part 50,
Chain 101 is squeezed towards inside, so that chain 101 is tensioned.
In the present embodiment, pretightning force part 50 is spring.Each stretching unit is provided with a spring as pretightning force part
50.It will be appreciated that the quantity of spring can also be according to the coefficient of elasticity of the requirement either spring itself of pretightning force size
Do quantitative adjustment.
In addition, in addition to spring, it is also possible to other be capable of providing active force that pressing piece 33 is squeezed towards chain 101
Part or device, such as elastic, the preferred spring of the present embodiment is as pretightning force part 50, on the one hand at low cost, good reliability,
On the other hand also more convenient to be installed and used in narrow space.
In the present embodiment, two stretching units are symmetrically arranged on pedestal 11.When being tensioned in this way to chain 101, chain
Extruding force suffered by item 101 is also more balanced, and the normal operation of chain 101 is avoided to be affected.
In the present embodiment, pedestal 11 has mounting groove, and motor mounting plate 200 offers spiral shell corresponding with installation groove location
Hole, pedestal 11 and motor mounting plate 200 pass through mounting groove by bolt and are fixedly connected with screw hole.
Further, the section of pedestal 11 is L-shaped, and the pedestal 11 of L tee section includes the first arm plate 112 and the second arm plate
114, mounting groove is opened in the second arm plate 114, and fixed part 13 is set to the second arm plate 114, and rocker arm 31 is articulated with by pin shaft
One arm plate 112.
In addition to those mentioned earlier, it is an option that pedestal 11 and motor mounting plate 200 weld.Equally can in this way
Stablize installation on motor mounting plate 200 so that strainer 100 is whole and play efficiency.
The principle of the present embodiment is:
Telescopic machine belt motor installation space is limited, this is difficult to the tensioning that chain 101 is carried out in a limited space.
More specifically, after belt motor installation, remaining space only has in the width direction of motor mounting plate 200
250mm (according to the difference of 200 local width of motor mounting plate, which can be changed), and since belt motor is to approach
The shell wall of telescopic machine shell, the size for allowing installation on the length direction of motor mounting plate 200 is then smaller, in short transverse
On space then only have motor sprocket to this little space of motor mounting plate 200.
For such narrow space, the present embodiment devises a kind of strainer 100, so that the chain of belt motor
101 are tensioned.
Specifically, connect connecting shaft 332 with fixed part 13 by spring, under the action of the restoring force of spring, rocker arm
31 can rotate towards 101 direction of chain, so that pressing roller 334 squeezes chain 101, and chain 101 is tensioned.
Symmetrical stretching unit is preferably used simultaneously, so that stress of the chain 101 in tensioning is more balanced, is mentioned
For be more good tension effects.
Pressing roller 334 itself can rotate, and not influence the rotation of chain 101.In addition the tension effects that pressing generates, in this way
Belt motor can guarantee that chain 101 and sprocket wheel snap tight against no matter in rotating forward or reversion process.
In addition, general chain stretching device needs periodic maintenance, and the strainer 100 of the present embodiment is without periodically adjusting
Whole 101 amount of tension of chain, uses more convenient.
The strainer 100 of the present embodiment, can be in belt motor institute by its own simple cleverly structure
Chain 101 is tensioned in the narrow installation space at place, telescopic machine is avoided to occur gear slippage phenomenon during the work time.
Embodiment 2
The embodiments of the present invention provide a kind of Expansion belt conveyor 1000, including belt motor mounting plate 200 and reality
The strainer 100 in example 1 is applied, the pedestal 11 of strainer 100 is installed on belt motor mounting plate 200.
1000 structure of Expansion belt conveyor of the present embodiment can be understood with the diagram in conjunction with the embodiments 1.
The other structures and function of Expansion belt conveyor 1000 can refer to the prior art.
By using the strainer 100 in embodiment 1, the chain 101 of the belt motor of Expansion belt conveyor 1000 can
It is tensioned, and without being periodically adjusted to amount of tension, job stability is more preferable, and reduces maintenance frequency, and use is more square
Just practical.
In conclusion the strainer 100 of the utility model is in mounting base by installing stretching unit, and pass through preload
Power part 50 provides pretightning force to stretching unit, and the pressing piece 33 of stretching unit is enabled to press and make chain 101
Chain 101 is tensioned, to realize the tensioning of chain 101 in the installation space of narrow belt motor.
And due to the lasting active force for having spring, the amount of tension of chain 101 available guarantee always, without regular
Amount of tension is adjusted, it is very convenient reliable.For Expansion belt conveyor 1000 by using the strainer 100, job stability is more preferable,
Gear is not susceptible to jump tooth.
The above descriptions are merely preferred embodiments of the present invention, is not intended to limit the utility model, for this
For the technical staff in field, various modifications and changes may be made to the present invention.It is all in the spirit and principles of the utility model
Within, any modification, equivalent replacement, improvement and so on should be included within the scope of protection of this utility model.
