Abstract
The present invention provides a clamp-type lifting hook for long and heavy steel rails, which is characterized in that a fixed pin is fixed between two outer support frames. A clamp arm and a connecting rod are symmetrically arranged in a cavity between the front part and the rear part of the outer support frames. The middle part of the clamp arm is provided with a vertical long hole, and the clamp arm is sheathed in the fixed pin through the long hole. The lower part of the clamp arm is clamped on the clamping parts of the steel rails, the contact surfaces of the clamping parts and the steel rails are inclined surfaces, and the inclination angles of two inclined surfaces are mutually adaptive. Because the clamping parts of the clamp arm and the steel rails are contacted by the surfaces, and the two contact surfaces are reliably and tightly abutted, the phenomena of scratch, impression and steel rail damage can not occur in the processes of lifting and carrying. Thus, the quality of the steel rails is ensured in the processing of loading and unloading.
Description
The present invention relates to a kind of suspension hook that is used for the handling long and heavy steel rails, say so in more detail the structural development of the hoist tool of existing handling rail.
The long rail of the frequent handling 25M of harbour AT STATION,, and the existing special tool that is specifically designed to the loading and unloading rail is to adopt steel wire buckle to tie up lifting, adopt steel wire buckle to tie up lifting and then exist some defectives significantly: 1, adopt the wire binding lifting, owing to be that a contact contacts with line, very easily rail is caused surface tear, impression and distortion, scrap to cause whole rail.2, extension is plucked the steel wire buckle inconvenience, has influenced handling efficiency.People are expecting that always a kind of technical scheme that can overcome above-mentioned defective produces as early as possible.
The purpose of this invention is to provide a kind of clamp-type lifting hook for long and heavy steel rails, it can be implemented in the purpose of not damaging (bad) rail in the handling process.
In order to achieve the above object, technical scheme of the present invention is: it comprise a pair of before, the outer support frame that the back is provided with, the left and right sides, middle and lower part is fixed with set pin between two outer support frames, before outer support frame, left and right sides symmetry in the cavity between the back is equipped with jig arm and connecting rod, the lower end of two connecting rods is connected by the upper end of connecting rod pin with two jig arm, the upper end of two connecting rods is connected with suspension ring by the suspension ring pin, the jig arm middle part has the strip hole of above-below direction, jig arm is sleeved in the set pin by above-mentioned strip hole versatilely, the jig arm bottom is the holding part of clamping rail, be crotch shape, the contact surface of holding part and rail is the inclined-plane, and the gradient on two inclined-planes is suitable.
Be symmetrically fixed with locating dowel pin in the left and right sides, two outer support frame middle and upper parts, have the groove that can fall into locating dowel pin on the top of two jig arm.
The one insurance pin-and-hole that can insert safety plug is arranged at two outer support frames middle parts.
The thickness of the holding part of described jig arm is at 16～25mm.
The present invention compared with prior art has the following advantages and good effect: 1, because the holding part of jig arm is that face contacts with rail, and the inclined-plane of two contact surfaces is suitable, jig arm and rail are fitted closely reliable, thereby can not occur the phenomenon of scuffing, impression and damage (bad) rail in the handling process, thereby guaranteed the rail quality in the handling process.2, be provided with locating dowel pin, can guarantee the jig arm clamping and positioning, jig arm is not dislocated when handling.3, adopt connecting rod and jig arm transmission location, accurate and safe and reliable, it is quick and convenient that dress is plucked suspension hook, improved handling efficiency.4, adopt safety plug, further reinforced safety, even under the situation of weightlessness, phenomenon can not break off relations yet.
Below in conjunction with accompanying drawing the present invention is described in detail.
Fig. 1 is a semisectional view of the present invention;
Fig. 2 is a side sectional view.
1, outer support frame; 2, suspension ring; 3, connecting rod; 4, safety plug; 5, jig arm; 6, rail; 7, locating dowel pin; 8, connecting rod pin; 9, suspension ring pin; 10, strip hole; 11, set pin; 12, holding part; 13, groove; 14, insurance pin-and-hole; 15, clamp-type lifting hook.
Referring to Fig. 1 and Fig. 2, the outer support frame 1 that a pair of forward and backward setting is arranged, the left and right sides, middle and lower part is fixed with set pin 11 between two outer support frames 1, left and right sides symmetry in the cavity between outer support frame 1 is forward and backward is equipped with jig arm 5 and connecting rod 3, the lower end of two connecting rods 3 is connected with the upper end of two jig arm 5 by connecting rod pin 8, the upper end of two connecting rods 5 is connected with suspension ring 2 by suspension ring pin 9, and jig arm 5 is rotated around connecting rod pin 8.Jig arm 5 middle parts have the strip hole 10 of above-below direction, jig arm 5 is sleeved in the set pin 11 versatilely by above-mentioned strip hole 10, this strip hole 10 can make jig arm 5 move up and down along strip hole 10, jig arm 5 bottoms are holding parts 12 of clamping rail 6, be crotch shape, holding part 12 is inclined-planes with the contact surface of rail 6, and the gradient on two inclined-planes is suitable, it is closely reliable to guarantee like this to fit, and the thickness of the holding part 12 of jig arm 5 is 20mm.Be symmetrically fixed with locating dowel pin 7 in the left and right sides, two outer support frames, 1 middle and upper part, shoulder has the groove 13 that can fall into locating dowel pin 7 on two jig arm 5.The one insurance pin-and-hole 14 that can insert safety plug 4 is arranged at two outer support frames, 1 middle part.
During operation, the operating personnel hands outer support frame 1, double fastener arm 5 and connecting rod 3 are then under the effect of gravity, double fastener arm 5 opens automatically, at this moment, set pin 11 is in the upper position of strip hole 10, locating dowel pin 7 is outside groove 13, double fastener arm 5 is clamped in rail 6 both sides, and pulling suspension ring 2 drivening rods 3 and 5 actions of double fastener arm put its clamping in place, at this moment, set pin 11 is in the lower position (as shown in Figure 1) of strip hole 10, locating dowel pin 7 falls in the groove 13, safety plug 4 is inserted put in place then, can lift by crane.During decoupling device, extract safety plug 4 hand-held outer support frames 1, just clamp-type lifting hook 15 can be taken away from rail 6.
