Description
Technical Field
The utility model relates to a lift technical field especially relates to a construction elevator anti-falling device.
Background
The construction elevator is also called a construction elevator, the simple construction elevator consists of a lift car, a driving mechanism, a standard knot, an attached wall, a chassis, a fence, an electrical system and the like, is a manned cargo-carrying construction machine frequently used in buildings, is comfortable and safe to take due to the unique box body structure, is usually matched with a tower crane to use on a construction site, generally has the carrying capacity of 0.3-3.6 tons and the running speed of 1-96M/min, and is more mature and gradually international in China.
The existing construction elevator is mainly characterized in that a strong spring is added at the bottom to prevent the car from falling off, and professional anti-falling equipment cannot be installed like a market elevator due to the limitation of field conditions, so that the safety is not high, and therefore a simple and effective device is needed to prevent the elevator from falling.
Disclosure of Invention
The utility model aims at solving the problem that the safety of the construction elevator in the prior art is poor and the defect of an effective anti-falling device is avoided, and providing the anti-falling device of the construction elevator.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
construction elevator anti-falling device, including the stand, stand one side internal weld has the cardboard, and the inboard card of stand is equipped with the lift case, the tachymeter is installed to lift bottom of the case portion both sides, and the welding of lift bottom of the case portion has the motor cabinet, surface bolted connection has the motor under the motor cabinet, motor output end joint has the gear, and the welding of lift bottom of the case portion has first cardboard and second cardboard, first cardboard reaches the inboard card of second cardboard is equipped with the pinion rack.
Preferably, the two sides of the toothed plate are provided with clamping grooves matched with the first clamping plate and the second clamping plate.
Preferably, the surface latch of the toothed plate is meshed with the gear.
Preferably, one end of the velocimeter is positioned inside one side of the bottom of the lifting box.
Preferably, the distance between the two clamping plates is greater than the height of the toothed plate.
The utility model has the advantages that:
the anti-falling device for the engineering elevator is simple in structure and convenient to install, the elevator can be effectively prevented from falling, and when the elevator accidentally falls, the motor can be quickly activated, so that the lift car can be stopped in time, and the life and property safety is protected.
Drawings
Fig. 1 is a schematic structural view of a fall protection device of a construction elevator according to the present invention;
fig. 2 is the utility model provides a construction elevator anti-falling device's partial section structure schematic diagram.
In the figure: 1 stand, 2 cardboard, 3 lift casees, 4 tachymeters, 5 motor cabinets, 6 motors, 7 gears, 8 first cardboard, 9 second cardboards, 10 pinion rack.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.
Referring to fig. 1-2, construction elevator anti-falling device, including stand 1, 1 one side of stand internal weld has cardboard 2, 1 inboard card of stand is equipped with cage 3, tachymeter 4 is installed to 3 bottom both sides of cage, 3 bottom welding of cage have motor cabinet 5, 5 lower surface bolted connection of motor cabinet has motor 6, 6 output end joints of motor have gear 7, 3 bottom welding of cage have first cardboard 8 and second cardboard 9, the inboard card of first cardboard 8 and second cardboard 9 is equipped with pinion rack 10.
The draw-in groove with first cardboard 8 and the 9 complex of second cardboard is seted up to pinion rack 10 both sides, and pinion rack 10 surface latch meshes with gear 7 mutually, and 4 one end of tachymeter is located inside bottom one side of lifting box 3, and the distance is greater than the height of pinion rack 10 between two cardboard 2.
In this embodiment, 3 blocks of cage 3 are established in stand 1 inboard, the mounting hole has been seted up to the bottom both sides of cage 3, its internally mounted tachymeter 4, the tip of tachymeter 4 should be located inside one side of cage 3, prevent to hit when daily using badly, cage 3's bottom welding motor cabinet 5, motor cabinet 5 bottom bolted connection motor 6, motor 6's output joint gear 7, cage 3's bottom still welds first cardboard 8 and second cardboard 9, pinion rack 10 is established to its inboard card, two pinion rack 10 are located the upper and lower both sides of gear 7 respectively, and the latch that the pinion rack surface was seted up meshes with gear 7.
Further, stand 1 one side inside even welding cardboard 2, the distance is greater than the height of pinion rack 10 between two adjacent cardboard 2, when unexpected the emergence, 3 speeds of lifting box are surveyed to tachymeter 4 and are exceeded the setting value, signals make the operation of motor 6, 7 rotatory drive pinion racks 10 of gear of motor 6 output stretch out, make pinion rack 10 block establish into cardboard 2 in, block the further whereabouts of lifting box 3, thereby reach protection lifting box 3 inside personnel and property safety.
The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
