Abstract
The invention relates to a hydraulic car lift with four guide rails and two sets of safety tongs, which comprises a lift car, a diversion sheave, a speed limiter and an oil cylinder, wherein the lift car is respectively connected with the first set of safety tongs and the second set of safety tongs; the four guide rails are respectively connected with the first set of safety tongs and the second set of safety tongs; the first set of safety tongs are connected with the second set of safety tongs through connecting rods for the safety tongs; lifting rods for the safety tongs are connected with the connecting rods for the safety tongs; and the speed limiter is connected with the lifting rods for the safety tongs. In the invention, a link gear with four guide rails and two sets of safety tongs are used for lifting the center of the lift car, thus the lift has reasonable stress, convenient installation and smooth operation.
Description
Technical field:
The invention relates to a kind of hydraulic car lift that uses four guide rails and two sets of safety tongs.
Background technology:
At present, common hydraulic car lift adopts three kinds of safety tongs structures usually, and the one, adopt a six roots of sensation guide rail and a sets of safety tongs, bottom girder adopts cant beam, the anti-rope structure of 2:1; This complex structure, materials are many, install difficultly, and obligatory point is many; Second kind is to adopt two guide rails and a sets of safety tongs, and bottom girder adopts cant beam, the anti-rope structure of 2:1; The third is to adopt four guide rails and a sets of safety tongs, and bottom girder adopts cant beam, the anti-rope structure of 2:1; Second kind stressed bad, yielding with the third car, and operation is unstable.
Summary of the invention:
In order to address the above problem, the invention provides a kind of hydraulic car lift with four guide rails and two sets of safety tongs, and it has simplified type of drive greatly, makes car structure simple; The interlock of employing two sets of safety tongs, stressed reasonable, easy for installation, operate steadily.
Technical scheme: hydraulic car lift with four guide rails and two sets of safety tongs, it comprises car, diversion sheave, oil cylinder; Described car is connected with second sets of safety tongs with first sets of safety tongs respectively, four guide rails are connected with second sets of safety tongs with first sets of safety tongs respectively, connect by the safety tongs connecting rod between first sets of safety tongs and second sets of safety tongs, the safety tongs lifting rod is connected with the safety tongs connecting rod, and velocity limiter is connected with the safety tongs lifting rod.
The beneficial effect of the invention, the four guide rails and two sets of safety tongs link gear is adopted in the invention, and it has simplified type of drive greatly, makes car structure simple; Promote the car center, elevator is stressed rationally, and is easy for installation, operates steadily.
Description of drawings:
Fig. 1: be the structural representation of the invention.
The specific embodiment:
As shown in Figure 1, a kind of hydraulic car lift with four guide rails and two sets of safety tongs, it comprises four guide rails 9, four guide rails 9 are connected with second sets of safety tongs 6 with first sets of safety tongs 2 respectively, car 1 is connected with second sets of safety tongs 6 with first sets of safety tongs 2 respectively, connect by safety tongs connecting rod 3 between first sets of safety tongs 2 and second sets of safety tongs 6, diversion sheave 5 is connected with safety tongs connecting rod 3, oil cylinder 4 is connected with diversion sheave 5, safety tongs lifting rod 7 is connected 3 with the safety tongs connecting rod, and velocity limiter 8 is connected with safety tongs lifting rod 7.
