Detailed description of the invention
Below, by reference to the accompanying drawings, structure of the present utility model and principle of work etc. are further described.
See Fig. 1, crane track comprises and is arranged at rail pressing plate 2 on track foundation 1 and I-shape rail 3, and I-shape rail 3 comprises rail head 301, the web of the rail 302 and the flange of rail 303 3 part.Crane track safety rope anchor fitting of the present utility model is installed on I-shape rail 3, it comprises two hook plates 4, 5 and lie in becket bridle 6 on one of them hook plate, two hook plates 4, 5 i.e. the first hook plate 4 and the second hook plates 5 as shown in the figure, first hook plate 4 has horizontal part 401 and is connected to the kink 402 of horizontal part 401, second hook plate 5 has horizontal part 501 and is connected to the kink 502 of horizontal part 501, horizontal part 401, 501 are arranged at the upper surface 3011 of the rail head 301 of rail 3 and are threaded connection part connection, wherein, threaded connector can select screw bolt and nut, as shown in the figure, horizontal part 401, 501 are mutually stacked and are connected and fixed by bolt 8 and nut (not shown), hook is in the both sides of the lower surface 3012 of the rail head 301 of rail 3 respectively for kink 402,502, and preferably, the free end of kink 402,502 can be butted on the web of the rail 302 place, to strengthen the steadiness of this device.
See Fig. 2, and composition graphs 3, Fig. 4, in order to the rail making crane track safety rope anchor fitting be applicable to plurality of specifications, and it is quick and easy for installation, the horizontal part 401 of the first hook plate 4 offers bar hole 4011, becket bridle 6 is arranged in this bar hole 4011, and the horizontal part 501 of the second hook plate 5 offers two bolts hole 5011, and bolt 8 is rotary with nut in order to the first hook plate 4 and the second hook plate 5 to be connected and fixed through bolt hole 5011 and bar hole 4011 successively.When this device is used for the rail head of different in width, only needs to pull down one of them bolt 8 and unscrew another bolt 8, the second hook plate 5 just can be pulled to slide along bar hole 4011, can be installed on rail head 301 until slide into.Equally, as shown in Figure 2, for ease of installing, also only needing one of them bolt 8 is dismantled and another bolt 8 is unscrewed, the second hook plate 5 being rotated to certain angle around another bolt 8, thus this device is easily installed on rail head 301.
In order to prevent becket bridle 6 to be hooked to for a long time by the second hook plate 5, becket bridle 6 is ruptured, as shown in Figure 1, bar hole 4011 is the side of kink 502 away from rail 3 having the position of becket bridle 6 to be positioned at the second hook plate 5.
For being damaged when avoiding becket bridle 6 stressed, as a kind of optimal way, as shown in Figure 3, bar hole 4011 has the waist shaped hole of circular arc for end.
For improving the safety factor of this device further, becket bridle 6 can adopt galvanized steel wire rope, is not easy fracture.
As shown in Figure 1 and Figure 2, the installation of crane track safety rope anchor fitting of the present utility model and use procedure as follows:
A, pull down one of them bolt 8 and unscrew another bolt 8, the second hook plate 5 is rotated to certain angle around another bolt 8;
B, the first hook plate 4 is hooked the lower surface 3012 of rail head 301, and the second hook plate 5 is slid into along bar hole 4011 side that kink 502 arrives rail head 301 to the right, then the second hook plate 5 is rotated back to level attitude;
C, the second hook plate 5 is slid into along bar hole 4011 lower surface 3012 that second hook plate 5 hooks rail head 301 left, finally load onto the bolt 8 that disassembles and tighten two nuts;
On the safety strap worn one safety rope 7 is hung on the life rope 9 in high-altitude by d, operating personnel, and another root safety rope 7 is hung on the becket bridle 6 of this device, can carry out operation.
The unloading process of crane track safety rope anchor fitting of the present utility model, by above-mentioned installation and use procedure reverse operating, repeats no more herein.
Certainly, crane track safety rope anchor fitting of the present utility model is also applicable to the driving surface that other has I-shape rail.
Above, be only schematic description of the present utility model, it will be recognized by those skilled in the art that on the basis of not departing from principle of work of the present utility model, can make multiple improvement to the utility model, this all belongs to protection domain of the present utility model.
