Abstract
The utility model relates to a novel two torsional springs are prevented weighing down device, including the lift hull, lift hull side is provided with the stand, and the stand side is provided with the hydraulic press, and hydraulic press upper portion is provided with the safety hook fixing base, and inside being provided with of safety hook fixing base prevents weighing down couple and two torsional springs, prevent weighing down the couple with two for the torsional spring pivort fixation on the safety hook fixing base, it is provided with tractive electromagnet to prevent weighing down couple upper portion. Safety hook fixing base lower part is provided with prevents weighing down the hook plate. The utility model discloses a device adopts the torsional spring formula to prevent falling, and installation space is little, the phenomenon of not opening can not appear, need not remove along with the hull, and it is convenient to walk the line, has improved the result of use.
Description
Technical field
The utility model belongs to hydraulic lifting technical field, is specifically related to a kind of novel torsion spring anti-drop device.
Background technology
At present, hydraulic pressure simple lifting falling proof device has two kinds on the market, a kind of is the catching device of shaft extension type, if this catching device hydraulic system has backhaul phenomenon, catching device is not easily opened, and another kind is also gravity type, but this catching device will move along with hull, need mounting spring line like this, and spring wire is very short for application life.Which adds maintenance cost.
Utility model content
The utility model relates to a kind of novel torsion spring anti-drop device, to improve anti-fall effect better, is convenient to use as required.
To achieve these goals, the technical solution of the utility model is as follows.
A kind of novel torsion spring anti-drop device, comprise lifting hull, lifting hull side is provided with column, column side is provided with hydraulic press, hydraulic press top is provided with catching device holder, catching device holder inside is provided with anti-fall hook and torsion spring, and anti-fall hook and torsion spring bearing pin are fixed on catching device holder; Anti-fall hook top is provided with tractive magnet.
Further, catching device holder bottom is provided with anti-fall hook plate.
In this device, hydraulic pressure simple lifting column increases a catching device holder, catching device holder penetrates an axle, add a torsion spring, make anti-fall hook maintenance can stopping, a tractive magnet is added at anti-fall hook opposite side, ensure that anti-fall hook can be opened safely, after anti-fall hook is encountered in the rising of lifting hull, anti-fall hook is regained thereupon, lifting hull continues to rise, after putting in place, anti-fall hook is due to the torsion recovery stopping of torsion spring, when picking up the car, tractive magnet is energized, by anti-fall opening of hook, lifting hull moves down safely.During bicycle parking, the upwards lifting of lifting hull, by anti-fall hook upwardly, after lifting hull is raised to position, anti-fall hook can set back due to the torsion of torsion spring anti-fall hook plate, plays anti-fall effect.When picking up the car, tractive magnet promotes anti-fall hook downwards, makes anti-fall opening of hook, and after time delay in a second, power unit electromagnetic valve is opened, and lifting hull moves downward, until lifting hull falls earthward.
The beneficial effect of this utility model is: this utility model device adopts torsion spring type fall arrest, and installing space is little, there will not be phenomenon of not opening, and need not move along with hull, and cabling is convenient, improves result of use.

Fig. 2 is the I place partial enlargement structural representation in Fig. 1.
Description of symbols in figure: 1, column; 2, hull is elevated; 3, hydraulic press; 4, anti-fall hook plate, 5, catching device holder; 6., anti-fall hook; 7, torsion spring; 8, tractive magnet.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described, better to understand the utility model.
Novel torsion spring anti-drop device as shown in Figure 1 and Figure 2, comprise lifting hull 2, lifting hull 2 side is provided with column 1, column 1 side is provided with hydraulic press 3, hydraulic press 3 top is provided with catching device holder 5, catching device holder 5 inside is provided with anti-fall hook 6 and torsion spring 7, and anti-fall hook 6 and torsion spring 7 bearing pin are fixed on catching device holder 5; Anti-fall hook 6 top is provided with tractive magnet 8.Catching device holder 5 bottom is provided with anti-fall hook plate 4.
In this device, hydraulic pressure simple lifting column 1 increases a catching device holder 5, catching device holder 5 penetrates an axle, add a torsion spring 7, anti-fall hook 6 is kept can stopping, a tractive magnet 8 is added at anti-fall hook 6 opposite side, ensure that anti-fall hook 6 can be opened safely, after anti-fall hook 6 is encountered in the rising of lifting hull 2, anti-fall hook 6 is regained thereupon, lifting hull 2 continues to rise, after putting in place, anti-fall hook 6 is due to the torsion recovery stopping of torsion spring 7, when picking up the car, tractive magnet 8 is energized, anti-fall hook 6 is opened, lifting hull 2 moves down safely.During bicycle parking, the upwards lifting of lifting hull 2, by anti-fall hook 6 upwardly, after lifting hull 2 is raised to position, anti-fall hook 6 can set back due to the torsion of torsion spring 7 anti-fall hook plate 4, plays anti-fall effect.When picking up the car, tractive magnet 8 promotes anti-fall hook 6 downwards, and anti-fall hook 6 is opened, and after time delay in a second, power unit electromagnetic valve is opened, and lifting hull 2 moves downward, until lifting hull 2 falls earthward.
The above is preferred embodiment of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications are also considered as protection domain of the present utility model.
