Description
Technical field
The utility model relates to a kind of elevator gear, belongs to engineering machinery field.Be a kind of cage elevator device preventing tilting specifically.Its widespread use in various iron and steel with high main equipment, coal gas producing company, metallurgy, equipment manufacturing, the production of making industries such as high buildings and large mansions, upkeep operation.
Background technology
Being commonly called as the device for " cage ", is a kind of deliveries such as operating personnel, article to be risen to certain altitude, carries out the lifting mode toter of aloft work.
Need be when the high-altitude deliver operating personnel and machine material when aloft work, the safety control of lifting jacking equipment and important, mostly weight-lifting equipment has and prevents the control setup that overloads, and control forms is single.Do not have the control setup of ultralight and prevent that wirerope from skidding off the device of fixed pulley.Only depend on the operating personnel to concentrate, reach safe operation.Therefore often take place because when aloft work, operating personnel and machine material are too laid particular stress in the position of cage, and cage deflects away from normal trace when descending, and causes the stranded halfway formula of cage to be blocked, or hang dragon dropped to the bottom, hinder for some reason, cause the wire rope drum of hoisting machine, fail in time to shut down, be longer than jack point and by the length of jack point to making wirerope, skid off the fixed pulley on the cage, even the cage knockdown, lead to potential safety hazard.
The utility model content
The technical problems to be solved in the utility model is: a kind of cage elevator device preventing tilting is provided, it can be when the cage elevator descends, prevent because of unexpected " stranded " formula Halfway Stopping decline, but transmission device is still continuing the operation that descends, cause wirerope to skid off harm such as lifting pulley, cage inclination, thereby ensure that people carry out aloft work safely.
In order to solve the problems of the technologies described above, the utility model is by the following technical solutions: a kind of cage elevator device preventing tilting, comprise cage, by wirerope and cage bonded assembly wire rope drum, the two ends of described wire rope drum are fixed on the bearing seat, wire rope drum is controlled it by motor and change-speed box and is rotated to drive the lifting of cage, wherein, described cage elevator device preventing tilting also comprises being installed in and is used to detect the sensor that cage bears a heavy burden under the bearing seat.
In described cage elevator device preventing tilting, described cage is provided with and wirerope bonded assembly attaching parts, and described wirerope is connected with attaching parts by fixed pulley; Be provided with around wirerope rectangle elastic shelf on described fixed pulley top, respectively be provided with a spring on one group of opposite side of described elastic shelf, respectively be provided with a roller on another group opposite side.
In described cage elevator device preventing tilting, described cage elevator device preventing tilting also comprises the sound and light alarm module, and described sound and light alarm module is connected with sensor.
In described cage elevator device preventing tilting, described cage elevator device preventing tilting also comprises signal display module, and described display module is connected with sensor.
Cage elevator device preventing tilting described in the utility model, utilization cage jacking system is installed in and is used to detect the sensor that cage bears a heavy burden under the bearing seat, realizes anti-light design.Promptly when the cage lifting descends, prevent because of the decline of its accident " stranded " formula Halfway Stopping, but transmission device is still continuing the operation that descends, cause wirerope to skid off harm such as lifting pulley, cage inclination, ensure that people carry out aloft work, a kind of compound type safety convenience instrument that uses safely in lifting mechanism.Its integrate anti-dry running the locking control of detection, wirerope, sound and light alarm, stop automatically, function such as no electro spark is explosion-proof.It is skillfully constructed and the message feedback link few, the fault cause is few, and is practical, safe and reliable.Be to gaholder, when building building, high tower etc. need to raise maintenance, the desirable safety protection device of loading operation personnel and workpiece lifting.
Description of drawings
Fig. 1 is the structural representation of cage elevator device preventing tilting described in the utility model.
The specific embodiment
Below, for a more detailed description to the utility model in conjunction with the accompanying drawings with embodiment.Present embodiment only is the description to the utility model preferred forms, scope of the present utility model is not had any restriction.
Embodiment
As shown in Figure 1, be the structural representation of cage elevator device preventing tilting described in the utility model.Described cage elevator device preventing tilting comprises motor 1, change-speed box 2, wire rope drum 3, bearing seat 4, sensor 5, connects rebound 6, display module 7, sound and light alarm module 8, wirerope 9, roller 10, elastic shelf 11, fixed pulley 12, attaching parts 13, cage 14 and fixed frame 15.
Described motor 1 is connected with change-speed box 2 and drive speed transmission 2; Change-speed box 2 is connected with wire rope drum 3, and wire rope drum 3 is given in power transmission; Be wound with wirerope 9 on the described wire rope drum 3, can roll up, put wirerope, the reel shaft is connected with bearing seat 4; Described bearing seat 4 carrying wire rope drum 3 stressed and position rotating; It is stressed that sensor 5 is used to detect wire rope drum 3, and be transferred to electric power controller, display module 7 and acousto-optic alarm module 8.Connecting rebound 6 fixedly positioning motor 1, transmitter 2, bearing seat 4; Display module 7 is used to show the accurate weight when operation is subjected to load; The load-carrying of sound and light alarm module 8 reports generation in service kicks the beam or is overweight; Wirerope 9 is used for promoting or decline cage 14; Roller 10 is used for the clamping wirerope, prevents that wirerope from crossing the race that skids off fixed pulley 12 behind the pine, and avoiding breaking down enlarges or potential safety hazard.Elastic shelf 11 remains to roller 10 transfer elastic tension force, prevents that wirerope 9 from skidding off roller 10 races and fixed pulley 12 races; Fixed pulley 12 is used for sliding block joint wirerope and cage, transmits energy; Attaching parts 13 is used for fixing at cage 14 tops and location fixed pulley 12.
