Description
Technical field
The utility model relates to a kind of elevator safety device, specifically relates in commercial production and the constructions work elevator safety device of transportation-production material up and down.
Background technology
At present, transport simple and easy jacking equipment that building materials uses as seen in the constructions work of building field everywhere, and these simplified elevators lack safety precautions, the accident of initiations such as wire cable rupture happens occasionally.
Chinese patent 02126620.4 discloses a kind of " anti-drop device for lifting cage of elevator ", the gin wheel that promptly promotes the cage top is connected with lifting cage entablatrance by the lineal bar of the lifting of fluting, shock mount between gin wheel and the entablatrance, gin wheel is connected by the oblique tie-rod of slotting with the supporting base at entablatrance two ends, rotating shaft is housed in the supporting base, rotating shaft two flat end Extension support seat axis holes are made no key with the oblique tie-rod elongated slot of fluting and are connected, the bar of encorbelmenting is housed in the middle of the rotating shaft, have the wedge of tooth line to be contained in left and right sides in the safety block, the wedge rear side has the locating dowel pin of groove parallel with the inclined-plane and safety block correspondence position to move to join.This patent application complex structure, cost of manufacture is higher.
Summary of the invention
The purpose of this utility model aims to provide a kind of safe and reliable elevator safety device.
To achieve these goals, elevator safety device of the present utility model hits bow, pedestal, slip by main shaft, auxiliary catch, counterweight, rotation and hits bow, and auxiliary catch peg and support are formed, and described support is arranged on the cage and captive joint; Described auxiliary catch peg is arranged on the crane and crosswise fixed connects or with elevator standard knot integrated setting; Top and captive joint or the integrated setting that bow is arranged on cage every post extension hit in described slip; Described pedestal is arranged on the support and captive joint, and pedestal is set to " Ω " type; Described main shaft interts in pedestal also free to rotate; Two ends and the captive joint that bow is arranged on main shaft hit in described rotation, rotates to hit to bend to be set to selenodont; Described counterweight is arranged on the main shaft and captive joint; Described auxiliary catch is arranged on the main shaft and captive joint, and auxiliary catch is corresponding with counterweight to be arranged on the main shaft; The bow integrated setting is hit in main shaft, auxiliary catch, counterweight and rotation, can rotate around pedestal, rotates to hit to bend with slip and hits the corresponding setting of bow.
Elevator safety device of the present utility model compared with prior art has following excellent effect:
Safe and reliable.When rising to operational level, elevator craning cage stops, the cage door upwards holds up, just can load and unload building materials, when the cage door upwards holds up, the slip at top, door pillar extension, both sides is hit to bend to answer back to rotate and is hit bow, main shaft is rotated, driving auxiliary catch simultaneously rotates and is hooked on the auxiliary catch peg, when fracture takes place in the steel rope at cage top, hang on the auxiliary catch peg by auxiliary catch, the auxiliary catch peg is fixedly connected on the crane, and cage still is positioned at the original place and can not drops, and has avoided the generation of injury accident.
Reasonable in design, simple in structure, make easily, with low cost, be suitable for using on the simplified elevator.
Description of drawings
Fig. 1 is the plan sketch that the auxiliary catch of elevator safety device separates with the auxiliary catch peg.
Fig. 2 is that the auxiliary catch of elevator safety device is hooked on the plan sketch on the auxiliary catch peg.
Be auxiliary catch wherein: 1) be main shaft, 2), 3) be counterweight, 4) hit bow, 5 for rotating) and be pedestal, 6) hit bow, 7 for sliding) and be the auxiliary catch peg, 8) be support, 9) be the cage door, 10) be door pillar, 11) be cage.
The specific embodiment
Elevator safety device shown in Figure 1 is by main shaft 1, auxiliary catch 2, counterweight 3, bow 4 is hit in rotation, pedestal 5, bow 6 is hit in slip, auxiliary catch peg 7 and support 8 are formed, support 8 is fixedly connected on the cage header doorframe, auxiliary catch peg 7 crosswise fixed are connected on the crane, perhaps with elevator standard knot integrated setting, slip is hit bow 6 and is arranged on cage every post top, 10 extension and captive joint or integrated setting, pedestal 5 is arranged on the support 8 and captive joint, pedestal 5 is made as " Ω " type, main shaft 1 interts in pedestal 5, and it is free to rotate, the two ends captive joint of main shaft 1 rotates and hits bow 4, auxiliary catch 2 and counterweight 3 correspondences are fixedly connected on the main shaft 1, main shaft 1, auxiliary catch 2, the integrated setting that bow 4 is hit in counterweight 3 and rotation, can wholely in pedestal 5, rotate, finish the safe operation purpose of insurance, rotation is hit bow 4 and is made as selenodont.
Stop when cage 11 rises to operational level, the cage Fomento rises when opening the door, and slides to hit bow 6 and answer back to rotate and hit bow 4, and auxiliary catch 2 is hooked on the auxiliary catch peg 7, disconnects elevator control power supply simultaneously.
After the material in the cage 11 is unsnatched, when the cage door is closed, slide and to hit bow 6 and hit again to rotate and hit bow 4, main shaft 1 is rotated, main shaft 1 rotating band auxiliary catch 2 and is rotated, and auxiliary catch 2 is separated with auxiliary catch peg 7, connects elevator simultaneously and controls power supply.
