Abstract
The utility model discloses a self-adaptive fixed-point clamping gravity type steel billet hanger. The self-adaptive fixed-point clamping gravity type steel billet hanger comprises a supporting frame, a bracket and two structurally symmetrical clamp arms; the self-adaptive fixed-point clamping gravity type steel billet hanger is characterized in that a vertical guide slot is arranged at the center of the supporting frame, wherein a guide post is arranged on the center of the bottom of the bracket; the guide post is arranged in the guide slot; the upper end of each clamp arm is hinged with a connecting rod; the two connecting rods are hinged; the middle parts of the two clamp arms are hinged with the bracket by a pin roll, respectively; the positions at which the two clamp arms are hinged with the bracket are arranged at the two ends of the bracket; the lower parts of the positions, at which the two clamp arms are hinged with the bracket, are hinged with one end of a linking rod by the pin roll; and the other end of the linking rod is hinged with the supporting frame by the pin roll. The whole device can be used for automatically compensating the distance between a jaw and a supporting mechanism in a clamping process of the hoisted steel billet, so that the distance between the clamping position and the upper surface of the steel billet is almost constant, thereby solving a problem that the hoisting cannot be normally carried out due to the influences of width and thickness changes of the steel billet on the hoisting during the large-scale clamping process of the steel billet.
Description
Technical field
The utility model relates to a kind of hoisting and hanging equipment, specifically a kind of steel billet stone tongs.
Background technology
Steel billet is as steel freak oil, for further rolling various section bars provide blank, be the original blank of all section bars, in the process that arrives subsequent processing, it is essential that the transhipment lifting of steel billet becomes, and billet hanger becomes the crucial hoist tool in the steel industry production.
Existing billet hanger mainly is divided into gravity type boat davit billet hanger and electric translational type billet hanger by its power resources.
The electric translational type billet hanger is to utilize screw rod transmission, produce initial pressure by spiral, utilize wedge to clamp, this kind billet hanger whole height remains unchanged in hoisting process, and because it is driven by power, can add easily various controls, can realize automation by electrical equipment control, in hoisting process, generally can there be the process of slip in principle in wedge clamps, so the thickness to steel billet has basic requirement, so that certain sliding distance to be provided, realize clamping, the change width scope of steel billet there is not any requirement.But because of the reason of himself, as: hanger structure is complicated, not easy care; Bulky, from great, affect effective hoisting capacity of hoisting crane; Need driven by power, limit etc. to some extent the field of employment, electronic billet hanger is used be subject to very big restriction, and in supporting steel billet hoisting crane use procedure, also often because a variety of causes appearance folder is not tight, fall the base phenomenon, it is superseded that existing market has been tending towards.Originally supporting electronic steel billet hoisting crane also has been transformed into mechanical billet hanger successively.
The gravity type boat davit billet hanger is to rely on the steel billet deadweight to realize a kind of billet hanger that clamps, and is divided into again adjustable billet hanger and non-adjustable billet hanger according to the difference of its supporting mechanism.Adjustable billet hanger is divided into again manual regulation billet hanger and motorized adjustment billet hanger according to the power resources of its adjusting.Be divided into again according to the mode of its adjusting and have level to regulate billet hanger and a step-less adjustment billet hanger.
The gravity type boat davit billet hanger in use is necessary for suspender a failure-free support is provided.
The supporting mechanism of non-adjustable billet hanger is fixed.Because the running orbit of jaw is circular arc, jaw is different apart from the distance of supporting mechanism when lifting the steel billet of every kind of width, the lifting scope is larger, differ just larger, if this just cause the lifting width range large steel billet, then require the thickness of steel billet must reach certain value, simultaneously because the increase of steel billet thickness also can cause billet hanger overload itself, so this suspender is only suitable for Fixed width or the little steel billet lifting of width range.
Adjustable gravity billet hanger, supporting mechanism can be regulated height.According to the manual or electronic adjustment supporting mechanism height of the width of lifting, with the needs of satisfied lifting, manual regulation, labor strength is large, use inconvenience, motorized adjustment, complex structure, be not easy to safeguard, there be requirement the field of employment, and usually be accompanied by the transformation of original driving.
No matter be the manual regulation billet hanger, or the motorized adjustment billet hanger, its purpose has fixing adjusting setting just for the design that realizes the different number of plies steel billets of handling, and the billet hanger supporting mechanism can only stop in the fixed position.After finishing, adjusting is equivalent to non-adjustable billet hanger.
In recent years, along with steel flourish, a kind of in the steel billet---slab, its width is increasing, has reached unprecedented 4500mm, and iron and steel enterprise is in order to reduce hoisting cost, require the lifting scope of billet hanger also increasing, expect that a billet hanger satisfies the lifting needs when the whole steel billets of procedure as much as possible, this just requires a kind of new billet hanger, can realize that width clamping on a large scale and its clamped height are almost constant.
The utility model content
The purpose of this utility model provides a kind of self adaptation fixed point clamping gravity billet hanger, and solve large width range steel billet that prior art exists can't be with same suspender lifting, when overcoming steel billet and lifting on a large scale, and the impact on lifting of width of steel billet and thickness; Realization is in whole lifting scope, no matter how width of steel billet and thickness change, the jaw bite of billet hanger and the distance of supporting mechanism are almost constant, realize that supporting mechanism and jaw are servo-actuated, realize the fixed point clamping, satisfy the lifting of the large steel billet of the lifting on a large scale, particularly thinner thickness of steel billet and change width scope.
The purpose of this utility model is come specific implementation by the following technical programs:
Self adaptation fixed point clamping gravity billet hanger comprises the tong arm of bracing frame, support and two symmetrical configuration, and the center of support frame as described above is provided with vertical guide groove, and the bottom centre of described support is provided with guidepost, and described guidepost is installed in the described guide groove; The upper end of each described tong arm and a rod hinge connection, hinged between two described connecting rods; Medium position at two tong arms is undertaken hinged by a bearing pin and described support respectively, the hinged position of two tong arms and support is positioned at the two ends of support, hinged by an end of bearing pin and gangbar with the hinged bottom, position of support on tong arm, the other end of described gangbar is hinged by bearing pin and bracing frame, whole formation adaptive equalization supporting mechanism.
Support frame as described above and described support adopt respectively symmetrical structure, and support frame as described above adopts inverted T shape structure, and described support adopts T shape structure.
Between two described tong arms, be provided with synchronizer gear, the two ends of described synchronizer gear are hinged on respectively on two tong arms, effect by synchronizer gear, can control both sides tong arm synchronization action, keep strokes, be conducive to the realization of Hoisting Security and suspender automatic shutter action, removed existing suspender for the action of switch circuit controller and eliminate the extra dof that clamp structure causes and cause the tong arm can not synchronization action and the backward technology that guidepost forces the tong arm synchronization action is set.
