Abstract
The invention discloses a self-locking composite conducting wire hoisting hook. The self-locking composite conducting wire hoisting hook comprises a hanging ring and conducting wire hooks, wherein the hanging ring is arranged on a crossbeam; the conducting wire hooks comprise an upper conducting wire hook and a lower conducting wire hook, which are connected with each other to form a whole body through a connecting rod and the crossbeam, and are respectively connected with the connecting rod to form a U-shaped storage structure for storing a conducting wire; the center of the hanging ring stays on a same straight line with the centers of the U-shaped storage structures of the upper and lower conducting wire hooks; and each U-shaped storage structure is provided with a self-locking mechanism for preventing the conducting wire from dropping off. The self-locking composite conducting wire hoisting hook can ensure that gravity core of the conducting wire does not deviate in hoisting; and through the self-locking design, the conducting wire is prevented from dropping from the hook in hoisting, and can be locked firmly and unlocked automatically, so that the working time does not increase, and the hoisting safety and reliability can be improved.
Description
Technical field
The present invention relates to the multiple wire load hook of a kind of self-locking type.
Background technology
At present, the multiple wire lifting gear of existing transmission line of electricity is widely used, but known this kind of lifting gear exists shortcoming all in various degree, such as, not on the same line, its centre of gravity skew when causing lifting, lower wire easily comes off for suspension ring and upper lower wire suspension hook.
Along with the fast development of power grid construction, 66kV-330kV transmission line of electricity adopts multiple traverse design on a large scale, and when overhauling, the lifting of multiple wire will often run into.Answer this demand, being applicable to the multiple wire Special sling hitcher of 66kV-330kV transmission line of electricity self-locking type has very real research and development to be worth.
The multiple wire Special sling hook of 66kV-330kV transmission line of electricity self-locking type is not only applicable to the multiple wire lifting work of 66kV-330kV, is applicable to single conductor lifting simultaneously yet and uses.
Summary of the invention
Object: in order to overcome the deficiencies in the prior art, the invention provides the multiple wire load hook of a kind of self-locking type.
Technical scheme: for solving the problems of the technologies described above, the technical solution used in the present invention is:
The multiple wire load hook of a kind of self-locking type, comprises suspension ring and wire hook, it is characterized in that: described suspension ring are arranged on crossbeam; Described wire hook comprises upper conductor hook and lower wire hook, and described upper conductor hook and lower wire hook are connected as a single entity by pipe link and crossbeam; Described upper conductor hook and lower wire link up with the U-shaped contained structure be connected to form with pipe link respectively for holding wire; Described hang Ring current distribution and upper conductor is linked up with and lower wire is linked up with U-shaped contained structure be centrally located on same straight line; Described U-shaped contained structure is provided with the self-locking mechanism for preventing wire dropping.
The multiple wire load hook of described self-locking type, it is characterized in that: described self-locking mechanism comprises self-lock rod and the locating dowel pin of " 7 font ", described self-lock rod is connected with the free end side of wire hook by rotating shaft, and described locating dowel pin to be arranged on pipe link with rotating shaft opposite position for limiting the turned position of self-lock rod.
Preferably, the multiple wire load hook of described self-locking type, is characterized in that: described crossbeam is vertical with pipe link to be arranged.
Beneficial effect: the multiple wire load hook of self-locking type provided by the invention, hangs being centrally located on same straight line of Ring current distribution and upper conductor is linked up with and lower wire is linked up with U-shaped contained structure, and when ensure that lifting, center of gravity does not offset; Adopt the self-locking type design of upper conductor hook and lower wire hook, when ensure that lifting, wire can not come off away in suspension hook, in use, locking is firm, and automatic unlocking, does not increase work-hours, safe and reliable instrument is easily provided for power transmission lines overhauling personnel play repetition wire, greatly reduce the labour intensity of personnel on tower, improve the safety and reliability of lifting work, further increase efficiency and professional level that power transmission line column works.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is use schematic diagram of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is further described.
As depicted in figs. 1 and 2, the multiple wire load hook of a kind of self-locking type, comprise suspension ring 1 and wire hook, suspension ring 1 are arranged on crossbeam 2; Wire hook comprises upper conductor hook 4 and lower wire hook 5, and upper conductor hook 4 and lower wire hook 5 are connected as a single entity by pipe link 3 and crossbeam 2; Crossbeam 2 is vertical with pipe link 3 to be arranged; Upper conductor hook 4 and lower wire are linked up with 5 hooks and are connected to form U-shaped contained structure 6 for holding wire respectively with pipe link 3; The U-shaped contained structure 6 that the center of suspension ring 1 and upper conductor are linked up with and lower wire is linked up be centrally located on same straight line; U-shaped contained structure 6 is provided with the self-locking mechanism for preventing wire dropping.Described self-locking mechanism comprises self-lock rod 7 and the locating dowel pin 8 of " 7 font ", described self-lock rod 7 is connected with the free end side of wire hook by rotating shaft 9, and described locating dowel pin 8 to be arranged on pipe link with rotating shaft 9 opposite position for limiting the turned position of self-lock rod 7.
As shown in Figure 2, the working process of the multiple wire load hook of self-locking type of the present invention is as follows: the U-shaped contained structure 6 of suspension ring 1, upper conductor hook 4 and lower wire hook 5 be centrally located on straight line, when ensure that lifting, center of gravity does not offset; During use, suspension ring 1 hang on weight-lifting equipment, upper conductor 10 and lower wire 11 are hung on upper conductor hook 4 and lower wire hook 5, mention suspension ring 1, utilize the principle that the gravity of wire is contrary with lifting force, under wire gravitative pressure, press against self-lock rod 7 difference 9 left-hand revolutions around the shaft, form closedown structure with wire hook, upper conductor and lower wire difference coupler lock are linked up with inside 5 at upper conductor hook 4 and lower wire, ensure that the safety of lifting work; After lifting work completes, in the process put down by suspension hook, under the effect of self gravitation, automatic 9 clickwises around the shaft of self-lock rod 7, automatically terminate locking, return to open state as shown in Figure 1.
The above is only the preferred embodiment of the present invention; be noted that for those skilled in the art; under the premise without departing from the principles of the invention, can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
