Description

Movable detachable platform

Technical Field

The utility model relates to a helicopter air park technical field, concretely relates to removes and to dismantle platform.

Background

The helipad plays an important role as a main activity area of the helicopter. The helicopter parking apron is a field for vertical take-off and landing of a helicopter, and is generally required to be provided with corresponding navigation aid equipment, navigation tube communication equipment, meteorological facilities, fire rescue equipment, airport sign marks and the like, so that the helicopter parking apron can meet the requirement of safe take-off and landing of the helicopter.

The existing movable detachable helicopter apron has the following defects on the lower supporting and adjusting part:

1. because every stress point all has three pile foundation to be supporting, consequently still must guarantee that every stress point three pile foundation is in same straight line when guaranteeing every stress point at a straight line when assembling the air park, in case the place height difference is too many or the installation error when the installation, all can arouse the load arrangement inequality of every stress point, it is very big that a pile foundation load is very big in the possible stress point, and the emergence on-the-spot of two other pile foundations hangs, thereby influence the bearing structure of whole air park.

2. With the ground contact surface on the small side, receive helicopter dynamic load to concentrate, in old patent, because the iron pile foundation of taking, consider that special district needs the manpower transport, consequently can not make into large tracts of land pile foundation, for this reason little with the ground contact surface, the atress load is concentrated, sinks easily in contact position ground, must often adjust the bracing piece many times and guarantee the plane degree of air park deck, wastes time and energy and not good adjustment.

3. The bracing piece manual regulation, it all needs to lean on the jack to realize to adjust at every turn, all need to do the flatness test to every bracing piece position after every helicopter takes off and land, if surpass then need the adjustment, because whole platform has whole connection during the adjustment, consequently in case need adjust, then must all demolish the bolt of bearing diagonal part earlier, adjust the screw hole of main tributary brace again, main tributary brace adjusts and removes bearing diagonal and pile foundation again after accomplishing and keeps the main part steady, consequently adjust at every turn all very troublesome.

Disclosure of Invention

Technical problem to be solved

In order to overcome the prior art not enough, the detachable platform is removed now to provide, it all has three pile foundation to form a complete set because every stress point of platform bottom, consequently still must guarantee that every stress point three pile foundation of every stress point is at same straight line when guaranteeing every stress point when assembling the air park, in case the place difference of height is too many or installation error when the installation, all can arouse the load arrangement inequality of every stress point, it is very big to have a pile foundation load in the stress point, and the emergence on the unsettled scene of two other pile foundations, thereby influence the stress structure's of whole air park problem.

(II) technical scheme

The utility model discloses a following technical scheme realizes: the utility model provides a remove and to dismantle platform, including H type bearing aluminum beam, foamed aluminum plate and aluminum plate, the last welding of foamed aluminum plate has aluminum plate, there is through bolted connection on the aluminum plate H type bearing aluminum beam.
