Abstract
The utility model provides a semi-portal crane, which comprises a horizontal beam, a transmission gear, a touch rod, a position limit switch, a hook, a roller for steel rope. A transmission gear is mounted onto the upper portion of the horizontal beam, a touch rod is mounted onto one end of the horizontal beam, while a position limit switch is mounted onto the other end. The position limit switch is attached to the touch rod through the steel rope, one end of the steel rope passing through the hook is attached to the horizontal beam, while the other end is attached to the roller of the steel rope mounted onto the transmission gear. The utility model has advantages that through improvements, problem that heavy weight hurts workers will not occur because the hook will not pull the steel rope to be broken, and the rate of accidents of the enterprise is lowered.
Description
Technical field
The utility model belongs to lift heavy machinery apparatus field, and concrete is a kind of half gantry crane.
Background branch art
At present, employed half gantry crane in domestic enterprise workshop all is to be controlled by a travel switch, like this after travel switch breaks down, suspension hook can up stretch in uncontrolled continuation, broken up to steel rope, lifted weight can fall down to pound and hurt sb.'s feelings, and safety and production is brought serious hidden danger.
The utility model content
At the problem of above-mentioned existence, the purpose of this utility model provides a kind ofly can guarantee that the travel switch rear hanger that breaks down can not continue to rise and breaks half gantry crane of steel rope.
The technical solution of the utility model is: a kind of half gantry crane, comprise crossbeam, change speed gear box, touching lever, travel switch, suspension hook, wire rope drum, it is characterized in that: the top of crossbeam is equipped with change speed gear box, crossbeam one end is installed a touching lever, the other end is installed a travel switch, travel switch links to each other by steel rope with touching lever, and one of the steel rope that passes suspension hook links to each other with crossbeam, and the other end links to each other with wire rope drum on being installed in change speed gear box.
Advantage of the present utility model: through improving, steel rope can not appear breaking in suspension hook again causes weight to injure workman's problem by a crashing object, has reduced the accident rate of enterprise.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Now in conjunction with the accompanying drawings, the utility model is further specified.
As shown in Figure 1, the top of crossbeam 1 is equipped with change speed gear box 2, crossbeam 1 one ends are installed a touching lever 3, the other end is installed a travel switch 4, travel switch 4 and touching lever 3 link to each other by steel rope, one of the steel rope that passes suspension hook 5 links to each other with crossbeam 1, and the other end links to each other with wire rope drum 6 on being installed in change speed gear box 2.
When before switch break down when causing suspension hook 5 to continue to rise, suspension hook 5 makes that the steel wire between touching lever 3 and the travel switch 4 is no longer strained owing to catch on touching lever 3, travel switch 4 can disconnect, with regard to the electricity went off, suspension hook 5 promptly stops to have risen.
