Abstract
The utility model relates to a cushioning structure for a windproof inhaul cable. The cushioning structure comprises a pair of main plates. The upper ends of the main plates are connected with an inhaul lug on harbor machinery through a pin shaft, and the lower ends of the main plates are connected with an upper connector of the windproof inhaul cable through an upper pin shaft. Holes matched with the pin shafts in the main plates are round holes, and holes matched with the upper pin shafts are waist-shaped holes which extend longitudinally downwards along the main plates. A pair of cushioning plates is arranged on the inner sides of the main plates. Holes matched with the pin shaft and the upper pin shaft in the cushioning plates are round holes. The rated load of the cushioning plates is lower than the rated load of the main plates. The cushioning plates are additionally arranged on the inner sides of the connecting main plates of the windproof inhaul cable, and have a cushioning function, so that an impact load on the cushioning plates can be absorbed, the welding line of the inhaul lug of a main unit of the harbor machinery is protected, and the safety of the windproof inhaul cable is improved.
Description
Technical field
The utility model relates to the windproof safety device of harbour machinery, specifically a kind of buffer structure of windproof drag-line.
Background technology
Windproof drag-line generally is used for harbour machineries such as bridge crane, An Qiao, door machine, tyre crane, plays windproof fixation, and many harbours all have the typhoon process, and it is more important that windproof drag-line just seems.
The windproof drag-line that is used for harbour machinery; Generally form by upper binding head, middle connector, whorl brace rod and lower union joint; Upper binding head draws ear to be connected through arm-tie with cross sill on the machine host of port; Lower union joint is connected with the harbour ground anchor seat through otic placode, to play the fixedly effect of port machine in strong wind.
Above-mentioned windproof drag-line in use, the cross sill on the machine host of port draws the commissure of ear and main frame often by drawing crack, dangerous hidden danger is bigger.
Summary of the invention
The utility model provides a kind of buffer structure of windproof drag-line to the problems referred to above, and this buffer structure can protect the port machine host to connect the weld seam that draws ear, increases the safety of windproof drag-line.
Technical scheme according to the utility model: a kind of buffer structure of windproof drag-line; Comprise a pair of mainboard; The upper end of said a pair of mainboard links to each other with the ear that draws on being arranged on harbour machinery through bearing pin, and its lower end links to each other with the upper binding head of windproof drag-line through upper pin, and the hole that matches with said bearing pin on the said mainboard is a circular hole; The hole that matches with said upper pin is vertically to the waist-shaped hole that extends below along said mainboard; The inboard of said a pair of mainboard is provided with a pair of dash plate, and said dash plate is circular hole with the hole that said bearing pin and said upper pin match, and the rated load of said dash plate is less than specified year load of said mainboard.
The width W of said dash plate is less than the width W of said mainboard, and the thickness of said dash plate is smaller or equal to the thickness of said mainboard.
Said mainboard is the waist circular slab.
Said dash plate is the figure of eight plate that two ends are big, the middle part is little.
The technique effect of the utility model is: the utility model has been set up dash plate in the connection mainboard inboard of windproof drag-line, plays buffer action, can absorb the impact load that receives, and protection port machine host connects the weld seam that draws ear, increases the safety of windproof drag-line.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the left view of Fig. 1.
Fig. 3 is the structural representation of the mainboard in the utility model.
Fig. 4 is the structural representation of the dash plate in the utility model.
The specific embodiment
Be further described below in conjunction with the specific embodiment of accompanying drawing the utility model.
Among Fig. 1～Fig. 4, comprise and draw ear 1, bearing pin 2, mainboard 3, upper pin 4, upper binding head 5, middle bearing pin 6, middle connector 7, whorl brace rod 8, lower union joint 9, dash plate 10, circular hole 11, waist-shaped hole 12, circular hole 13, circular hole 14 etc.
Like Fig. 1, shown in Figure 2; Windproof drag-line comprises upper binding head 5, middle connector 7, whorl brace rod 8 and lower union joint 9; Middle connector 7 links to each other with upper binding head 5 through middle bearing pin 6; Middle connector 7 and lower union joint 9 are respectively through the opposite two ends that are threaded in whorl brace rod 8 of rotation direction, and lower union joint 9 is connected with the ground anchor seat at harbour through otic placode.
The utility model is a kind of buffer structure of windproof drag-line, comprises a pair of mainboard 3, and the upper end of this a pair of mainboard 3 links to each other with the ear 1 that draws on being arranged on harbour machinery through bearing pin 2, and its lower end links to each other with the upper binding head 5 of windproof drag-line through upper pin 4.
Through analysis, under the situation that only adopts a pair of mainboard 3, when the port opportunity arrives typhoon; Because typhoon speed is very big; When blowing on the machine host of port, caused an impact, made the main frame cross sill draw ear 1 and main frame place weld seam to tear in the junction of main frame and windproof drag-line; If wind speed is even, then this kind situation can not take place.
For the weld seam that prevents windproof drag-line and main frame junction is torn, the utility model is provided with a pair of dash plate 10 in the inboard of above-mentioned a pair of mainboard 3, and the rated load of dash plate 10 is less than specified year load of mainboard 3.
As shown in Figure 3, mainboard 3 is the waist circular slab, and width is W1, has two holes on it.Wherein, the hole that matches with bearing pin 2 on the mainboard 3 is a circular hole 11, and the hole that matches with upper pin 4 is vertically to the waist-shaped hole that extends below 12 along mainboard 3.The diameter of circular hole 11 is φ D, and the width of waist-shaped hole 12 is D, and length is D+A.
As shown in Figure 4, dash plate 10 is the figure of eight plate that two ends are big, the middle part is little.Dash plate 10 is circular hole 13,14 with the hole that bearing pin 2 and upper pin 4 match, and the diameter of circular hole 13,14 is φ D.The width W 2 at dash plate 10 middle parts is less than the width W 1 of mainboard 3, and the thickness of dash plate 10 so just can guarantee the specified year load of the rated load of dash plate 10 less than mainboard 3 smaller or equal to the thickness of mainboard 3.
The principle of work of the utility model is following: impact in case typhoon occurs, dash plate 10 will be elongated, in the process of elongating; Just offset impulsive force, thereby protected weld seam, made main frame unaffected; And when dash plate had been elongated the length of A, mainboard 3 was stressed, firm main frame.
The utility model has been set up dash plate 10 in connection mainboard 3 inboards of windproof drag-line, plays buffer action, can absorb the impact load that receives, and protection port machine host connects the weld seam that draws ear, increases the safety of windproof drag-line.
