Abstract
The invention discloses a load lifting limiter oil supporting device of a tower crane. The load lifting limiter oil supporting device comprises an oil supporting tank (1) and oil supporting tank supports (2). The oil supporting tank (1) is located at the position, around 20-50 mm away from a load lifting limiter (3), under the load lifting limiter (3), and connected to a rotation frame (4) of the tower crane above the oil supporting tank supports (2)through the oil supporting tank supports (2). A tank opening of the oil supporting tank (1) can cover the periphery of the load lifting limiter (3). Lubricant oil can be effectively prevented from being splashed to a tower body channel, a web member and other positions. Potential safety hazards caused when people pass through the channel are eliminated, the safety coefficient is increased, and the design of the tower crane is more humanized.
Description
Technical field
The present invention relates to a kind of load lifting limiter holder oil device, be particularly useful for tower crane.
Background technology
Existing tower crane must install load lifting limiter, it is requisite safety device on tower body hoisting crane, and when lifting by crane the weight of thing and reaching rated load, load lifting limiter will action, and cut off the power supply of crane hoisting mechanism vertical motion, stop overweight accident and occur.Load lifting limiter is arranged on the slewing frame position of tower machine usually, and killer connects with framework by general bolt and bearing pin, and during work, hoist rope is through killer pulley, and load lifting limiter can swing back and forth around bolt shank or bearing pin.But, due to steel rope having lubricating oil, tower machine normal work timing device pulley makes high speed gyroscopic movement with the motion of steel rope, lubricating oil now on hoist rope can be got rid of and be flown, lubricating oil can be splashed to the places such as tower body passage, web member, affect attractive in appearance, personnel by time also there is serious potential safety hazard.
Summary of the invention
For above-mentioned existing technical matters, the invention provides a kind of tower crane load lifting limiter holder oil device, fly on tower machine to avoid load lifting limiter place lubricating oil to be got rid of, cause unnecessary potential safety hazard.
For achieving the above object, the invention provides a kind of tower crane load lifting limiter holder oil device, comprise holder oil groove, drag oil groove support, described holder oil groove is positioned at immediately below load lifting limiter, distance is about 20-50mm place, and by dragging oil groove support to be connected on the slewing frame of tower machine of the side of being located thereon; And this holder oil groove notch can cover load lifting limiter periphery.
Further, the curved plate composition both described holder oil groove to be connected with primarily of two side plates, described curved plate is identical with the axis of load lifting limiter, and the arc radius of this curved plate is 1.4-1.6 times of load lifting limiter radius.
Preferably, the arc radius of described curved plate is 1.5 times of load lifting limiter radius.
During further enforcement, described holder oil groove is connected to by bolt, nut and drags on oil groove support.
In existing design, the load lifting limiter place of tower machine there is no the oily device of holder, and the load lifting limiter holder oil device that the present invention initiates has following advantage: 1, processing and manufacturing is simple, fast easily manufactured.
2, lubricating oil can be prevented to be splashed to the places such as tower body passage, web member.
3, the personnel that can eliminate, by there is serious potential safety hazard during passage, improve safety factor, make tower machine design hommization more.

Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.
As shown in Figures 1 to 5, the present invention includes holder oil groove 1, drag oil groove support 2.Holder oil groove 1 rectangular top four end connects four respectively by bolt 6, nut 7 and drags oil groove support 2.Four are dragged oil groove support 2 to be sling by semi-round holder oil groove 1 and are fixed on the slewing frame 4 above holder oil groove 1.
As shown in Figure 4 and Figure 6, holder oil groove 1 primarily of two arc side plates 8 and both being connected bottom curved plate 9 form, and be positioned at immediately below load lifting limiter 3, distance is about 20-50mm place, and notch can cover load lifting limiter periphery.Described curved plate 9 is identical with the axis of load lifting limiter 3, and arc radius is 1.5 times of load lifting limiter 3 radius, is got rid of the lubricating oil flown to catch easily by load lifting limiter 3.
During work, the oily device 1 of semicircle holder is positioned at below load lifting limiter 3, load lifting limiter 3 can be got rid of the lubricating oil flown and catch, should note avoiding itself and hoist rope 5 to interfere simultaneously.Said structure is simple, and outward appearance is clean and tidy, is easy to manufacture.By the application of this technology, the turret of XGTT125B is in and flashes phenomenon without greasy dirt, and the personnel that eliminate, by potential safety hazard during this place, meet engineering construction safety requirement.Meanwhile, very reference value is had to the design of other products.
