Abstract
The utility model relates to a limiting device of an air exchanger, which comprises a top plate arranged fixedly. A bottom plate is fixedly arranged under the top plate, a mounting column is arranged between the top plate and the bottom plate and is provided with a stroke switch, an ejection rod is inserted into the top plate and the bottom plate in a penetrating way, an impact plate is fixed on the ejection rod and is used for triggering the stroke switch, a reset spring is sleeved on the ejection rod between the top plate and the bottom plate, the top end of the reset spring props against the lower surface of the top plate, and the bottom end of the reset spring props against the impact plate. The limiting device has a simple structure and can be used conveniently, two stroke switches can be installed according to needs for dual security protection, and accident caused by the gate displacement can be avoided.
Description
Technical field
The utility model relates to a kind of stopping means, especially a kind of empty stopping means of handing over device.
Background technology
The existing empty stopping means of device of handing over is regulated very inconvenience, and repetitive positioning accuracy is relatively poor, and the adjustment stroke amount is less.
Summary of the invention
The purpose of the utility model is to overcome the deficiency that exists in the prior art, provides a kind of sky simple in structure, easy to use to hand over the stopping means of device.
According to the technical scheme that the utility model provides, the said empty stopping means of handing over device comprises hard-wired top board; Below top board, be installed with base plate, between top board and base plate, be provided with erection column, travel switch is installed on erection column; A push rod is inserted plate and base plate thoroughly; On push rod, be fixed with crash panel, crash panel is used to trigger described travel switch, on the push rod between top board and the base plate, is socketed with back-moving spring; The top of back-moving spring and the lower surface of top board offset, and the bottom and the crash panel of back-moving spring offset.
On erection column, be provided with the travel switch height adjustment mechanism.On push rod, be provided with the crash panel height adjustment mechanism.
On crash panel, be fixed with the trigger ramp plate.In the rotating shaft of stroke switch triggering, the triggering rocking bar is installed, is rotatablely equipped with travelling wheel at the leading section that triggers rocking bar, travelling wheel cooperates with described trigger ramp plate.
The utility model is simple in structure, easy to use, and two travel switches can be installed as required, and the insurance protection of two-pass Switching Two prevents that flashboard from crossing an accident.
Description of drawings
Fig. 1 is the front view of the utility model.
Fig. 2 is the vertical view of the utility model.
Fig. 3 is the user mode figure of the utility model.
Embodiment
Below in conjunction with concrete accompanying drawing and embodiment the utility model is described further.
As shown in the figure: this sky is handed over the stopping means of device, comprises hard-wired top board 1, below top board 1, is installed with base plate 2; Between top board 1 and base plate 2, be provided with erection column 3; 6, push rods of travel switch 4 are installed on erection column 3 insert plate 1 and base plate 2 thoroughly, on push rod 4, be fixed with crash panel 5; Crash panel 5 is used to trigger described travel switch 6; On the push rod 4 between top board 1 and the base plate 2, be socketed with back-moving spring 7, the lower surface of the top of back-moving spring 7 and top board 1 offsets, and the bottom of back-moving spring 7 and crash panel 5 offset.
On erection column 3, be provided with travel switch height adjustment mechanism 8.On push rod 4, be provided with crash panel height adjustment mechanism 9.
On crash panel 5, be fixed with trigger ramp plate 10, a travel switch 6 all is installed on the every erection column 3 of trigger ramp plate 10 1 sides, form the dual fail-safe protection.In travel switch 6 triggering rotating shafts, be equipped with and trigger rocking bar 11, be rotatablely equipped with travelling wheel 12 at the leading section that triggers rocking bar 11, travelling wheel 12 cooperates with described trigger ramp plate 10.
Be that bump push rod 4 moves up crash panel 5 and compression reseting spring 7 when flashboard 13 during to the position, travelling wheel 12 touches travel switch 6 from trigger ramp plate 10 is walked the upright side walls process of trigger ramp plate 10 belows, flashboard 13 is stopped.In case travel switch 6 damages or because of the other reasons akinesia, flashboard 13 continues up, touches a travel switch 6, and flashboard 13 is stopped, and plays the effect of duplicate protection.When flashboard 13 moved downward, the elastic force of back-moving spring 7 resetted crash panel 5, and travelling wheel 12 is walked again on trigger ramp plate 10, and travel switch 6 automatically resets.
Unclamp the nut on the travel switch height adjustment mechanism 8, setting height(from bottom) that can adjustment stroke switch 6; Unclamp the nut on the crash panel height adjustment mechanism 9, setting height(from bottom) that can crash panel 5.
