Abstract
An intelligent pressure sensing unit of a buffer comprises an oil cylinder, a piston, a separator, a buffer head, a mounting base and a throttle mandrel. One end of the throttle mandrel is connected with an electronic switch and the other end is equipped with a nut, the nut is connected with a connecting plate, and the connecting plate is connected with a protecting cover via a bolt. The intelligent pressure sensing unit leads an operating mechanism to be in power failure through an electronic switch connected with a liquid-gas buffer, can effectively protect the operating mechanism on various unreasonable working conditions, brakes in time, avoids unnecessary loss, and also prolongs service life on a normal condition.
Description
Technical field:
When the utility model related to hydro-pneumatic buffer and is impacted, the protection running gear made its automatic stopping, realizes the pressure sensor device of braking.
Background technology:
Hydro-pneumatic buffer plays the effect of protection running gear at walking cranes such as various running gears such as bridge crane, transfer gantry, gate seat, An Qiao, tower cranes, hydro-pneumatic buffer is a kind of energy-dissipating type snubber assembly, have high-level efficiency and reduction with good function, minimumly can absorb 90% bump energy, therefore stiff end is subjected to very little acting force, and bounce is also less relatively, and resetting of impact damper is to utilize the compression potential energy of gas to finish, and it is milder to reset; But because running gear bump at full speed usually, timely retarding braking causes when clashing into load excessive, and running gear and impact damper are all caused unnecessary damage.
Summary of the invention:
In order to solve the above problems, the utility model provides a kind of impact damper intelligent pressure sensing device, its electronic switch by linking to each other with hydro-pneumatic buffer, make the travelling mechanism outage, under a lot of unreasonable operating modes, can effectively play the protection travelling mechanism, in time braked, avoided unnecessary loss; Also effectively prolonged serviceable life under normal circumstances.
A kind of impact damper intelligent pressure sensing device, it comprises oil cylinder, piston, isolated body, the impact damper head, mount pad, the throttling mandrel is characterized in that: an end of described throttling mandrel is connected with electronic switch.
One end of described throttling mandrel is provided with nut, and nut is connected with web joint, web joint and protective cover.
The beneficial effects of the utility model are that an end of described throttling mandrel is connected with electronic switch, its electronic switch by linking to each other with hydro-pneumatic buffer, make the travelling mechanism outage, under a lot of unreasonable operating modes, can effectively play the protection travelling mechanism, in time be braked, avoid unnecessary loss; Also effectively prolonged serviceable life under normal circumstances.
Description of drawings: the utility model is described in detail below in conjunction with accompanying drawing.
Fig. 1: be structural representation of the present utility model.
Embodiment:
As shown in Figure 1; a kind of impact damper intelligent pressure sensing device; piston 10 slides in oil cylinder 5; be provided with isolated body 9 in the piston 10, an end of piston 10 is provided with impact damper head 11, and the outer wall of oil cylinder 5 is provided with mount pad 8; throttling mandrel 6 passes piston 10 and oil cylinder 5; one end of throttling mandrel 6 is connected with nut 12, electronic switch 1, and nut 12 is connected with web joint 4, and web joint 4 is connected with protective cover 2 by bolt 3.
