Description

A kind of safety rope hook

Technical field

The present invention relates to a kind of safety guard, more specifically, the present invention relates to a kind of safety rope hook.

Background technology

Present various super-pressure iron tower is the common equipment of remote distance power transmission, is that the angle steel by various different models is welded.When transmission equipment being overhauled and safeguards, the workmen will climb to operation on the iron tower of tens meters even tens meters, for preventing the unexpected degeneration of workmen, the general safety rope that adopts is done protection, safety rope one end bolt is between workmen's waist, other end bolt hangs over hook on the angle steel of super-pressure iron tower again and realizes on common hook.Common hook does not have the locking positioning device, rocks back and forth on angle steel, is easy to come off from angle steel, in emergency circumstances, can't realize the effect of safeguard protection, and security is very poor.

The Chinese patent ZL99223282.1 of 03 month 22 days Granted publications in 2000 discloses a kind of work high above the ground safety belt hook, and it comprises hook, it is characterized in that: the hinged locking bar of the opening part of hook; Assemble lock rod spring between locking bar and the hook; Hinged bumper bar on hook is assembled relief spring between bumper bar and the hook; Have the slip pin-and-hole of groove with lock on bumper bar, fixing sliding pin on the locking bar, sliding pin are installed in the slip pin-and-hole on the bumper bar.Advantage is: hook or decoupling device are convenient and swift, and operation is easily exempted the safety rope of colligation in the past trouble, uneasy congruent problem, and is safe and reliable.

The Chinese patent ZL200420052642.8 of 08 month 10 days Granted publications in 2005 discloses a kind of handcuffs formula safety belt hook, its structure comprises coupler body and the semicircular dead bolt that joins with coupler body, bolt locking mechanism and anti-locking mechanism, safety rope perforation place of the bottom of coupler body is an entity structure, the top of coupler body is the hook solid double-decker, dead bolt is arranged between the double-decker of coupler body, and with coupler body upper group structure circlewise, the upper end of dead bolt is hinged by the upper end of hinge and coupler body, the lower end locks together by bolt locking mechanism and coupler body, and the lower end of dead bolt also joins with anti-locking mechanism.

Though the hook of above-mentioned patent disclosure hook or decoupling device are convenient and swift, operation easily, but it all becomes ring-type similarly, be more suitable for and be hooked on the rod member of similar annular, cooperate with angle steel on the angle steel of super-pressure iron tower and use, can produce mutual collision, friction, even slide along angle steel, reduced the service life of hook, use dangerous simultaneously.

Summary of the invention

In order to address the above problem, the invention provides a kind of safer safety rope hook with locking positioning device.

For achieving the above object, safety rope hook of the present invention adopts following technical scheme:

A kind of safety rope hook, comprise hanger bulk, hanger bulk is made up of the crotch part on top and the straight bar part of bottom, it is characterized in that, described hook also comprises a latch, the through hole that the straight bar part of hanger bulk has at least one and latch to be slidingly matched, the position of described through hole make the latch that inserts in the through hole lean the horizontal segment that is hooked on the steel tower corner iron on the hook, and hook is fixed on the angle steel.

Wherein, preferably, latch is a straight pin.

Wherein, preferably, also comprise the latch fixture, the latch fixture be two respectively by the spring controlled steel ball of below separately, be installed in the two ends of the same diameter of the same circumference of latch; The annular groove that cooperates with steel ball is arranged in the through hole of the straight bar part of hanger bulk.

Wherein, preferably, also comprise a connection chain, this connection chain one end is fixed on an end relative with the insertion section on the latch, and the other end is fixed on the hanger bulk.

Wherein, preferably, latch has the handle portion of size greater than the insertion section.

Compared with prior art, the invention has the advantages that:

1, latch inner spring and ball will be linked up with on the angle steel of fixing high voltage iron tower securely, be difficult for moving, and be safe and reliable.

2, hanger bulk adopts the titanium alloy manufacturing, and is light and handy, firmly, the mechanical strength height, and volume is little, carries, easy to use.

3, be provided with a plurality of jacks, make hook be fit to the iron tower of various sizes.

Description of drawings

Fig. 1 is that the vertical profile of safety rope hook of the present invention is looked schematic diagram;

Fig. 2 is the left view of Fig. 1.

The specific embodiment

Below in conjunction with the drawings and specific embodiments safety rope hook of the present invention is further described.

As illustrated in fig. 1 and 2, safety rope hook of the present invention comprises hanger bulk 1 and latch assembly 2.

Hanger bulk 1 is basic identical with common hook, and top is a crotch, and the bottom is a straight bar part; There is a hole 5 that safety rope is installed the lower end of straight bar part, and the top in hole 5 is processed with 4 pin holes 6 along a vertical line direction, is processed with an annular groove 8 on one circumference of middle part in the hole 6.

Latch assembly 2 comprises latch 10, latch fixture 11, connection chain 12 and steady pin 13.Latch 10 is a ladder cylinder substantially, right-hand member is an insertion section 14 that is slidingly matched with the pin hole 6 of hanger bulk 1, the middle part is the cylinder handle portion 15 of convenient plug, and the diameter of handle portion 15 has an annular groove 17 greater than the diameter of insertion section 14 on the left end cylinder.Insertion section 14 is inserted in the hole 6 of hanger bulk 1 and is stretched out outside the hole 6.Latch fixture 11 be two respectively by the steel ball 21 of spring 20 control of below separately, be installed in the two ends of latch 10 respectively near the same diameter of a circumference of the insertion section 14 of handle portion 15.Annular groove 8 in steel ball 21 and the hanger bulk 1 cooperates, and prevents latch 10 landings.Steady pin 13 is a short cylindrical pin, is welded on a straight bar part side relative with crotch of hanger bulk 1, and an annular groove 19 is arranged on it.Connection chain 12 1 ends are fastened on the annular groove 17 of latch 10, and an end is fastened on the annular groove 19 of steady pin 13, prevent that latch 10 from extracting out after, be slipped on the ground.

During use, hanger bulk 1 is hung on the angle steel 30 of iron tower, latch 10 is inserted in the hole 6 that is fit to, make latch 10 lean horizontal component, fix thereby will link up with the angle steel 30 of iron tower at the angle steel 30 of iron tower.

Can select pin hole 6 according to the size of the angle steel 30 of superelevation iron tower.

Hanger bulk adopts the titanium alloy manufacturing, and is light and handy, firmly, the mechanical strength height, and volume is little, carries, easy to use.

, but should be understood that under the situation that does not break away from relevant protection domain defined by the claims that those skilled in the art can make change and/or revise according to embodiments of the invention describing the present invention property and nonrestrictive description.
