Description
(1) technical field
The present invention relates to a kind of construction elevator layer apparatus for door-opening.
(2) background technology
Construction elevator layer door be for being arranged on the floor material loading platform outside, and existing opening ways generally needs the elevator operator after construction elevator is accommodated to the floor position of platform and comes to a complete stop, and the opening elevator cab then is opened the latch of layer door behind the door; Need first close the floor protection door latch when closing, then close construction elevator cab door.Often owing to hand barrow being arranged during material loading in construction elevator, the construction elevator driver comes in and goes out more difficult; Sometimes after the workmen came in and went out, the construction elevator driver did not close layer door, and the workmen easily forms an often opening of layer door when not closing, and easily forms safety hazard.
(3) summary of the invention
In order to overcome defects, the invention provides a kind of construction elevator layer apparatus for door-opening, have simple in structure, only need construction elevator normal at the floor position stop position, need not construction elevator driver or workmen and carry out manual operation, the advantages such as closed condition when guaranteeing that layer door is normal improves the construction elevator operating efficiency, and layer door closed safe is reliable.
The technical solution adopted for the present invention to solve the technical problems is, this construction elevator layer apparatus for door-opening by: layer door locking apparatus, a layer door lock close registration device, easing lever device, spring-advance lever apparatus and up and down roller driving device and form.
Layer door locking apparatus root is an external diameter 36mm, internal diameter 10.5mm, the annulus of thick 10mm, wear diameter 10mm round steel in circle as rotating shaft, be welded on layer doorframe, layer door locking apparatus end is triangular in shape, diameter 16mm of middle part one side welding, the round steel that 60mm is long is opened passive lifting lever as door lock; The overhanging 10mm in triangle lower end prevents the door bolt dropout.
The door bolt that layer door lock closes registration device is diameter 16mm round steel, is fixed on No. 8 channel-section steels that are positioned at the doorframe outside.
The easing lever device is by an external diameter 36mm, internal diameter 12.5mm, the annulus of thick 10mm, wear the positioning pin rod of a diameter 12mm in annulus, annulus one end welding " L " type cross section is the square steel of 10mm*10mm, the long length of side 68mm of " L " type, and end, long limit downside is long 50mm minor face; The 10mm*10mm square steel (end is round end) that it is 27mm that annulus opposite side and rectangular steel become 135 ° of fillet welding spreadings.Positioning pin rod is welded on No. 8 channel-section steels in the doorframe outside, and positioning pin rod arranges the steel washer of 2 thick external diameter 20mm of 2mm in easing lever both sides, is used for the position of location easing lever.
The spring-advance lever apparatus is thick by a 3mm, the steel plate of 40mm*40mm is as the transmission base plate, be welded on the square steel drive link of 10mm*10mm, drive link passes a steel plate transmission locating plate that 5mm is thick, 40mm is high, locating plate is offered the square opening that is of a size of 10.5mm*10.5mm, and locating plate is welded on No. 8 channel-section steels in the doorframe outside.Overlapping between locating plate and transmission panel on drive link has spring, and spring force is not less than 10N.The drive link other end is connected by connecting pin with the transmission panel, and the transmission panel is thick by 3mm, and 46mm is wide, and the high steel plate of 105mm forms, and 30 ° of angles of inward at both ends lateral buckling, steel plate up and down are curvedly torn long 15mm open, and straight plate part divides high 75mm.Transmission panel inner central section position is welded with that two 3mm are thick, and 10mm is high, the connecting panel that 15mm is long, and between connecting panel, spacing is 12mm, the hole that it is 5mm that 7mm place, connecting panel end opens a diameter in the centre is as connecting bridge between transmission panel and transmission base plate.
The up and down roller driving device is by the steel roller of external diameter 76mm, height 50mm, internal diameter 12.5mm, the steel axle of wearing the 12mm diameter in the steel roller is fixed on turning rolls, the turning rolls both sides are that 2mm is thick, 50mm is high, the steel plate that 60mm is long, on the steel plate that the 3mm that is connected in the outside is thick, 50mm is high, 80mm is long, by welding with construction elevator cab lateral frame perpendicular to this steel plate, 3mm plate iron that to be positioned at two length of sides of both sides, steel plate up and down, the outside be the 32mm*40mm right-angled triangle.
Upper bottom roller moves by the up and down of construction elevator, when construction elevator moves to the floor platform, roller touches the spring-advance lever apparatus, and the transmission base plate is moved to layer door direction, promotes the quarter butt end of door lock opening device, make on door lock opening device stock end and revolve, drive the drive link of door lock closing appliance upwards, the door lock of door lock closing appliance is opened bar and is risen, and makes the door lock closing appliance break away from the location door bolt, the protection door lock is unlocked, and can open like this construction elevator floor layer door.
Install a spring installation, door bolt place and add a shock absorber at the door-hinge place of construction elevator floor layer door, when making layer Men Zaiwu External Force Acting, and can autoshutdown.During layer Men Zaiwu External Force Acting, rely on the action of the spring autoshutdown, when closing, the inclined-plane of the triangle shaped ends of door lock closing appliance is along the location door bolt slippage that makes progress, to back door lock closing appliance whereabouts, triangle bight, make the position gates pin card live the door lock closing appliance, a layer door lock closes like this.Move up and down at construction elevator, when leaving the floor platform, spring gear relies on spring reset, and opening device door lock easing lever under the stock self-gravity action falls.If do not start when leaving the floor platform at construction elevator, layer door is with regard to autoshutdown, still be in a high position because of easing lever this moment, easing lever end knee is in the inclined-plane state, when layer door outwards moves like this, locking-bar end snap close is opened bar and is contacted in advance the unlatching knee, and a layer door leaf makes the locking-bar slippage that makes progress under the effect of spring thrust, and snap close is opened bar just along the long limit downslide of easing lever " L " type when locking-bar slides onto the curved stock of easing lever upper end.When construction elevator left floor, the transmission base plate resetted under action of the spring, and easing lever falls, and locking-bar also falls to fastening the location door bolt thereupon, and layer door is lockable like this.
According to construction elevator layer door installation requirement, sealing baffle all need be installed in layer door latch position, prevent from opening layer door on the inboard floor platform of layer door, and layer door requires protection grid length of side maximum to be not more than 25mm, therefore, as prescribed requires the layer Men Buhui that arranges at will to be opened in floor.
The invention has the beneficial effects as follows, anchor fitting is simple in structure, need not manual operation, and saving of work and time has been saved the time of run of construction elevator, and safe and reliable, improves the operating efficiency of construction elevator.
