Abstract
The invention relates to the field of lifting equipment and in particular relates to a rope locking device of a lifting hook of a crane. The technical effect that the rope locking device of the lifting hook of the crane is safe and convenient and can protect a steel wire rope is achieved. The rope locking device of the lifting hook of the crane comprises a hook body and a hoop device formed by fixedly connecting a front clamping rod with a rear clamping rod; the hoop device is arranged at the hook neck of the hook body in a rotatable manner; a front clamping rod pin hole is formed in the front clamping rod; a rear clamping rod pin hole is formed in the rear clamping rod; insertion pins are arranged in the front clamping rod pin hole and the rear clamping rod pin hole; the front clamping rod, the rear clamping rod and the hook body form a closed annular structure, and the front clamping rod and the rear clamping rod are fixed through the insertion pins. The hoop device is additionally arranged at the hook neck of the hook body, so that the steady closed annular structure is formed; the steel wire rope positioned in the annular structure cannot fall off. The rope locking device of the lifting hook of the crane is ingenious in structural design and can be applied to the lifting hook of the crane in crane equipment.
Description
Technical field
The present invention relates to weight-lifting equipment field, especially a kind of crane hook lock rope device.
Background technology
At present, weight-lifting equipment is widely used in the operations such as the lifting, transportation of every field, and the material of lifting and lifting mode are also varied.For the purpose of safety, when lifting operation, the suspenders such as steel rope used in the gib head that is placed to crane hook group after, must lock, prevent that the suspenders such as steel rope from coming off from gib head.
General suspension hook coupler body does not carry the structure of locking steel wire rope, and what have individually locking mechanism also just simply utilizes clamp button of the spring to realize locking, and this is very inconvenient again when needs take out steel rope.
Summary of the invention
Technical matters to be solved by this invention is to provide a kind of crane hook lock rope device that can realize safely and easily steel rope protection.
The technical solution adopted for the present invention to solve the technical problems is: crane hook lock rope device, comprise coupler body, by front kelly, be fixedly connected with rear kelly the device for hooping forming, the rotating hook neck place that is arranged at coupler body of described device for hooping, on front kelly, be provided with front kelly pin-and-hole, on rear kelly, be provided with rear kelly pin-and-hole, in described front kelly pin-and-hole and rear kelly pin-and-hole, be provided with latch, the cyclic structure of front kelly, rear kelly and the sealing of coupler body formation and front kelly, rear kelly are fixed by latch.
Further, described device for hooping is fixedly connected with and forms with termination, rear kelly one end by termination, front kelly one end, and device for hooping is shaped as " L " type.
Further, comprise the clip mount pad at the hook neck place that is arranged at coupler body, described device for hooping is fixed on the hook neck place of coupler body by clip mount pad.
Further, clip mount pad is by being arranged at collar on hook neck and the nut that collar is fixed on hook neck being formed.
The invention has the beneficial effects as follows: by the hook neck place at coupler body, set up device for hooping, after steel rope be placed into tangle in coupler body, by device for hooping rotation is extremely formed to the cyclic structure of sealing with coupler body, again latch is inserted in front kelly pin-and-hole and rear kelly pin-and-hole and realizes device for hooping is fixed on coupler body, thereby build a firm closed circular structure, so far, just can there is not situation about coming off in the steel rope in this cyclic structure again.When using end, only latch need to be extracted, rotation device for hooping, can take out steel rope.Structure design of the present invention is ingenious, makes simply, can well pin steel rope, promotes safety in production, can be applied in the crane hook of crane facility.
Accompanying drawing explanation
Fig. 1 is the schematic diagram before locking of the present invention.
Fig. 2 is the schematic diagram after locking of the present invention.
Fig. 3 is the lateral plan after locking of the present invention.
In figure, be labeled as: coupler body 1, bill 11, back 12, hook neck 13, device for hooping 2, front kelly 21, front kelly pin-and-hole 211, rear kelly 22, rear kelly pin-and-hole 221, clip mount pad 3, steel rope 4.
The specific embodiment
Below in conjunction with accompanying drawing, the present invention is further described.
Crane hook lock rope device as shown in Figure 1, Figure 2, Figure 3 shows, comprise coupler body 1, by front kelly 21, be fixedly connected with rear kelly 22 device for hooping 2 forming, rotating hook neck 13 places that are arranged at coupler body 1 of described device for hooping 2, on front kelly 21, be provided with front kelly pin-and-hole 211, on rear kelly 22, be provided with rear kelly pin-and-hole 221, in described front kelly pin-and-hole 211 and rear kelly pin-and-hole 221, be provided with latch, the cyclic structure of front kelly 21, rear kelly 22 and coupler body 1 formation sealing and front kelly 21, rear kelly 22 are fixed by latch.
In conjunction with actual application, as shown in Figure 1, first device for hooping 2 rotations are opened, and steel rope 4 is placed in coupler body 1, then device for hooping 2 rotations are extremely formed to the cyclic structure of sealing with coupler body 1; And then latch is inserted in front kelly pin-and-hole 211 and rear kelly pin-and-hole 221, can realizes and will between front kelly 21, rear kelly 22 and coupler body 1, realize the cyclic structure that forms firm sealing.General, front kelly 21 contacts with bill 11, and rear kelly 22 contacts with back 12, so not only simple in structure, and very practical.
In order further to simplify the structure of device for hooping 2, can select such scheme: described device for hooping 2 is fixedly connected with and forms with rear kelly 22 terminations, one end by front kelly 21 terminations, one end, and device for hooping 2 is shaped as " L " type.As shown in Figure 1, the device for hooping 2 of " L " type can well contact and form with bill 11, back 12 cyclic structure of sealing.In addition, two limits of " L " type, the angle between front kelly 21 and rear kelly 22 need to be determined with coupler body 1 size, to guarantee forming closed circular structure, is as the criterion.
In order to facilitate removing and installing of device for hooping 2, can select such scheme: comprise the clip mount pad 3 at hook neck 13 places that are arranged at coupler body 1, described device for hooping 2 is fixed on hook neck 13 places of coupler body 1 by clip mount pad 3.Between the hook neck 13 of coupler body 1 and device for hooping 2, set up clip mount pad 3, can when needs take off device for hooping 2, directly from clip mount pad 3, take off, the diversification that has increased application for the present invention is like this selected.
Improvement based on to such scheme, clip mount pad 3 can be selected by being arranged at collar on hook neck 13 and the nut that collar is fixed on hook neck 13 being formed.As depicted in figs. 1 and 2, collar is fixed on hook neck 13 by nut, and then device for hooping 2 is fixed on collar by connecting elements such as nuts, not only can well complete and pin steel rope 4 technique effects, also can greatly simplify cost and operation while making.
