Description

The link gear of building construction hoist cage door and floor protective door

Technical field

The utility model discloses a kind of construction safety device, be meant a kind of link gear that is used for building construction hoist cage door and floor protective door especially.

Background technology

At present, building construction hoist is in charging, during discharging, generally material is transported to the floor that to stop by cage, cage is positioned at the floor derrick, the floor derrick is provided with the floor protective door, when cage stopping on the floor derrick appropriate after, the floor protective door of being located on the floor derrick is opened in advance, the cage door is opened then, workmen in the floor walks out in the floor protective door, enter in the cage and adorn, discharging work, behind the completed loading, the cage door is closed in advance, and the workmen after getting back to floor closes the floor protective door then, this setting exists some safety hazard: because the floor protective door belongs to different control system respectively with the cage door, the floor protective door is generally manually controlled to promote by workmen in the floor and is opened; The cage door is opened by the jacking system drive lifting that is located on the cage, belongs to elevator control system.Therefore when being used to indicate the device of rising of cage door or decline indication fault to occur, or operating troubles appears in the cage door in process of rising or falling, and the interior staff of floor this moment does not know this situation, still open the floor protective door and operate, then the safety misadventure that may meet accident and fall down from the building.

The utility model content

For addressing the above problem, the purpose of this utility model is to provide a kind of simple in structure, the building construction hoist cage door that safety performance is good and the link gear of floor protective door.

For achieving the above object, the technical solution adopted in the utility model is: this link gear comprises backing pin, block and swivel arm, backing pin is located between floor protective door and the cage door, be fixed on the cage bottom, both sides at the cage door all are provided with block and swivel arm, swivel arm one end is connected by axle with the cage door, the other end is a free end, block and cage door are for captiveing joint, block is positioned at the below of swivel arm, swivel arm becomes to be horizontally disposed with when cooperating with block, all is provided with groove at floor protective door two ends.

When cage stopping on the floor derrick appropriate after, this moment, the free end of swivel arm leaned on backing pin, swivel arm does not have with the floor protective door and is connected, jacking system on cage slowly promotes the cage door, swivel arm is owing to be connected by axle with the cage door, swivel arm rises with the cage couplet on the door is moving, swivel arm will rotate and trend level slowly, the free end of swivel arm stretches out to the floor protective door, when swivel arm continues to rise to when touching block, because swivel arm cooperates with block for being horizontally disposed with, swivel arm is in horizontality, the swivel arm free end is maximum to the length that the floor protective door stretches out, the swivel arm free end just can insert in the groove of floor protective door, make cage door and floor protective door upwards be promoted to the complete opening state simultaneously, at this moment, the loading and unloading personnel load and unload material work, behind the completed loading, by the jacking system on the cage cage door and floor protective door are slowly put down, when the cage student drops to the residing position of backing pin, cage bottom, insert the swivel arm in the floor protective door owing to be subjected to stopping of backing pin, from the groove of floor protective door, produce, thereby the closed condition of reverting to, this moment, cage door and floor protective door were thrown off, cage can move by easy on and off, thereby prevented effectively that under the situation that the cage door does not also arrive the floor protective door is opened, the incident that loading and unloading personnel accident is fallen down from the building takes place, the utility model is simple in structure, and is safe and reliable.

Further illustrate detailed content of the present utility model below in conjunction with the drawings and Examples explanation.
