Description
Technical field
The utility model relates to four post lifting machine technical fields, is specifically related to a kind of four post lifting machine Anti-breaking rope devices.
Background technology
Four post lifting machines are visual plants of vehicle maintenance and repair, for by vehicle hoisting to certain altitude, thus realize the maintenance of automobile.It mainly comprises column, holds car race plate, crossbeam, the driving system of lifting mechanism is driven by hydraulic efficiency pressure system and controls, the steel rope that the hydraulic ram installed under plate promotes to connect column and crossbeam is run by holding car, the big roller that crossbeam is installed is rolled along column, realizes holding car and run moving up and down of plate.
At present, usually the lifting of steel rope implementation platform is used in four post lifting machine equipment, but owing to occurring after misoperation, overload or steel rope Long-Time Service that the reasons such as wearing and tearing, fatigue damage can cause wire cable rupture, thus the automobile of lifting or other loads are fallen suddenly, cause great potential safety hazard.So usually can Anti-breaking rope device be arranged in four post lifting machine equipment; but existing Anti-breaking rope device generally adopts machinery anti-breaking, detect disconnected rope by mechanical device, after rope is disconnected, mechanical device triggers travel switch and makes electromagnet action; install complicated, speed of response is slow and cost is high.
Utility model content
The purpose of this utility model is for overcoming above-mentioned the deficiencies in the prior art, provides a kind of four post lifting machine Anti-breaking rope devices, adopts electrically anti-breaking, installs simple, is swift in response reliable.
For achieving the above object, the utility model adopts following technical proposals:
A kind of four post lifting machine Anti-breaking rope devices, comprise crossbeam, steel rope, broken step chain device, latch and electromagnet, described broken step chain device one end is provided with roller, roller contacts with steel rope, the broken step chain device other end and crossbeam fix, broken step chain device and crossbeam are in being arranged in parallel, electromagnet is fixedly installed on crossbeam, electromagnet is connected by push rod with latch, electromagnet, push rod and latch are installed on the same plane of crossbeam, described latch and crossbeam are hinged by bearing pin, and described broken step chain device, electromagnet are all connected with control circuit.
Described broken step chain device is fixed by bearing and crossbeam.
Described roller along the circumferential direction arranges arc groove, to make wire line shoe in groove, prevents steel rope slippage.
Described roller is connected with broken step chain device by rotating shaft, and roller rotates around the axis, and to reduce the friction between roller and steel rope, reduces the wearing and tearing of steel rope and roller.
The beneficial effects of the utility model are: by the setting of broken step chain device, realize electrically anti-breaking, disconnect at steel rope and make latch realize locking instantaneously, make the car race plate that holds of four post lifting machines stop declining, avoid dangerous generation, this device reaction rapidly, installation is simple, cost is low.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the close-up schematic view at I place in Fig. 1;
In figure: 1, steel rope, 2, column, 3, crossbeam, 4, roller, 5, rotating shaft, 6, broken step chain device, 7, bearing, 8, electromagnet, 9, push rod, 10, bearing pin, 11, latch.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further illustrated.
A kind of four post lifting machine Anti-breaking rope devices, as depicted in figs. 1 and 2, comprise crossbeam 3, steel rope 1, broken step chain device 6, latch 11 and electromagnet 8, broken step chain device 6 one end is provided with roller 4, roller 4 contacts with steel rope 1, roller 4 along the circumferential direction arranges arc groove, to make steel rope 1 be stuck in arc groove, prevents steel rope 1 slippage.Roller 4 is connected with broken step chain device 6 by rotating shaft 5, and roller 45 freely rotates around the shaft, to reduce the friction between roller 4 and steel rope 1, reduces the wearing and tearing of steel rope 1 and roller 4.
Broken step chain device 6 is fixed by bearing 7 and crossbeam 3, and broken step chain device 6 and crossbeam 3, in being arranged in parallel, so that steel rope 1 and roller 4 can contact well, are avoided occurring deflection, made roller 4 uniform force, ensures the sensitivity of broken step chain device 6.Electromagnet 8 is fixedly installed on crossbeam 3, and electromagnet 8 is connected by push rod 9 with latch 11.Broken step chain device 6 is positioned at the top of electromagnet 8.Electromagnet 8, push rod 9 and latch 11 are installed on the same plane of crossbeam 3, and layout is more simplified, convenient installation.Latch 11 and crossbeam 3 are hinged by bearing pin 10, and described broken step chain device 6, electromagnet 8 are all connected with control circuit.
When vehicle stops into four post lifting machines, steel rope 1 is in tension, roller 4 and steel rope 1 close contact of broken step chain device 6, under the application force of steel rope 1, broken step chain device 6 is in normally off, and electromagnet 8 and latch 11 are all in open mode, and four post lifting machines can realize normal lifting.When steel rope 1 ruptures suddenly because of wearing and tearing, overload or other reasons, broken step chain device 6 loses the tension force effect of steel rope 1, be in open mode, control circuit is power-off immediately, electromagnet 8 is in off-position, electromagnet 8 promotes push rod 9 and moves, latch 11 is in and rotates around bearing pin 10, one end of latch 11 snaps in the groove that column 2 is offered, thus realizes locking, stops crossbeam 3 to decline, thus the decline of car race plate is held in prevention, ensure device security, the groove number herein column 2 offered is several, and column 2 is from top to bottom equidistantly uniformly distributed.Disconnected rope locking process adopts electrically anti-breaking, is swift in response, makes electromagnet 8 action immediately, realize quick locking after disconnected rope, safe and reliable.
By reference to the accompanying drawings detailed description of the invention of the present utility model is described although above-mentioned; but the restriction not to the utility model protection domain; one of ordinary skill in the art should be understood that; on the basis of the technical solution of the utility model, those skilled in the art do not need to pay various amendment or distortion that creative work can make still within protection domain of the present utility model.
