A kind of conveyer baffle mechanism
Technical field
The utility model relates to the conveyer in the goods load transfer device, more particularly, relates to the baffle mechanism of conveyer.
Background technology
Conveyer is a kind of equipment that is used for air cargo terminal and other logistics disposal system, and its one or both ends are provided with baffle plate.Baffle plate has two control positioies: allow goods to enter or leave conveyer when baffle plate is fallen, stop goods to pass through when baffle plate rises.The method of change baffle plate control position has manually and dynamical element drives two classes.
As shown in Figure 1, for existing manually operated baffle plate 30a, by bearing pin 70a as the strong point, and be rotatably connected on the barrier support 10a by screw 80a, need hand that baffle plate 30a is pushed the forbidden state of goods from the goods feed status during operation, as shown in FIG., baffle plate 10a is pushed the position that is higher than driving surface from the driving surface position that is lower than delivery platform.
Conveyer baffle mechanism for this structure, if the conveyor surface of conveyer is lower, just must bend over when carrying out baffle plate mode of operation conversion operations like this, not only inconvenience but also increased labour intensity had increased unsafe factor simultaneously in actual mechanical process.

Above-mentioned conveyer baffle mechanism, its characteristics are that this foot-driven lever upper end is provided with a stretcher.
Above-mentioned conveyer baffle mechanism, its characteristics are that this foot-driven lever is connected by a bearing pin with this push rod.
Above-mentioned conveyer baffle mechanism, its characteristics are that this baffle plate is connected by a bearing pin with this push rod.
Above-mentioned conveyer baffle mechanism, its characteristics are that this baffle plate is connected by a bearing pin with this rack beam at this strong point.
Above-mentioned conveyer baffle mechanism, its characteristics are that this latch hook has a guiding surface.
Above-mentioned conveyer baffle mechanism, its characteristics are that the most significant end that is positioned at the baffle plate of raised position is higher than the driving surface of this delivery platform, and the most significant end that is positioned at the baffle plate of lowering position is not higher than the driving surface of this delivery platform.
Conveyer baffle mechanism of the present utility model is when carrying out baffle plate mode of operation conversion operations, and only using foot is stepped on pedal and baffle plate can be fallen, and mechanism is automatically locked at this position; Only using foot is stirred reset lever when the needs baffle plate rises, in the just rise automatically of effect lower baffle plate of spring force.Use not only convenient and strength-saving but also safety of this conveyer baffle mechanism.
Below in conjunction with the drawings and specific embodiments the utility model is described in detail, but it is not as to qualification of the present utility model.

The specific embodiment
As shown in Figure 2, conveyer baffle mechanism of the present utility model mainly comprises: barrier support 10, foot-driven lever 20, baffle plate 30, latch hook 40, lock hook shaft 50, reset attachment 60.This barrier support 10 can be arranged at the end of one or both ends of the delivery platform of conveyer according to actual needs, and the most significant end of its rack beam 11 is not higher than the driving surface 100 of this delivery platform.As shown in Figure 3, this foot-driven lever 20 can be a L type structure, be rotatably connected on this rack beam 11 by a bearing pin 70, its upper end can be provided with a stretcher 26, so that the operator tramples, the lower end is in transmission connection by a bearing pin 70 and a horizontally disposed push rod 22, and these push rod 22 other ends are connected with this barrier support 10 by a compression spring 24, and these foot-driven lever 20 1 sides also have a latch segment 21.These baffle plate 30 lower ends can be connected by bearing pin with this push rod 22, and pass through a bearing pin 13 as the strong point, are rotatably connected on this rack beam 11, and this baffle plate can rotate between raised position and lowering position around this strong point.As shown in Figure 4, this lock hook shaft 50 is connected on this barrier support 10 by a base 52, also is arranged with a latch hook 40 that is interlocked with this latch segment 21 with these latch segment 21 corresponding positions on it.This latch hook 40 has a guiding surface 42, as shown in Figure 3.This reset attachment 60 as shown in Figure 3 and Figure 4, comprises reset lever 61 and torsion spring 63, this reset lever 61 is connected in this lock hook shaft 50 1 ends, and this torsion spring 63 is set on this lock hook shaft 50, and the one end connects this reset lever 61, and the other end is in transmission connection with this latch hook 40 by this lock hook shaft 50.
Wherein, this foot-driven lever 20 rotates under external force, and its lower end also promotes this push rod 22 and is moved to the left, and this baffle plate 30 of the mobile drive of this push rod 22 rotates around this strong point 13.Latch segment 21 on foot-driven lever 20 moves downward to it is when the guiding surface 42 of this latch hook 40 slides, and latch hook 40 is forced outwardly side and rotates, and screwing spring 63 is tightened simultaneously.After latch segment 21 slips over guiding surface 42, under screwing spring 63 effects, latch hook 40 inwardly rotates immediately to hook and fastens this latch hook 40, stop latch segment 21 upward movements, this moment, this baffle plate 30 also rotated the driving surface below 100 that drops to this delivery platform, and this compression spring 24 also is compressed to the compression position place.Even this moment, foot-driven lever 20 no longer applied external force, baffle plate 30 still can remain on the decline state, makes that the goods on the conveyer is passed through, and foot-driven lever 20 and baffle plate 30 are as shown in phantom in Figure 2.
Opposite, when stirring this reset lever 61, reset lever 61 rotates latch hook 40 by lock hook shaft 50, and latch segment 21 is released.Under compression spring 24 effects, push rod 22 moves right, and baffle plate 30 rises and maintain the rise state, and this moment, its most significant end was higher than the driving surface 100 of this delivery platform, made goods be in forbidden state, and foot-driven lever 20 and baffle plate 30 are shown in solid line among Fig. 2.
Certainly; the present invention also can have other various embodiments; under the situation that does not deviate from spirit of the present invention and essence thereof; those of ordinary skill in the art work as can make various corresponding changes and distortion according to the present invention, but these corresponding changes and distortion all should belong to the protection domain of the appended claim of the present invention.
