Abstract
The utility model discloses a crane which has a simple structure, and is convenient to use, and can quickly lift cast-in-situ bridge crash barriers with hanging edges. The utility model comprises a trolley, wherein the trolley is provided with a hanging bracket, a inhaul cable and a lifting hook; the hanging bracket comprises a pedestal and a support; the support comprises a lifting rod, a supporting rod and a diagonal draw bar, wherein the lifting rod inclines toward the lifting hook direction, and the supporting rod is in vertical direction and encircles with the lifting rod to form an inverted triangle; the diagonal draw bar holds the supporting rod on the side surface; the middle of the pedestal is provided with a rotary supporting wheel and the pedestal can rotate on the trolley freely with the rotary supporting wheel; the side of the pedestal, which is opposite to the lifting hook, is extended to form a cantilever; the cantilever is provided with a clump weight and a motor. The utility model has a simple structure and a lower manufacturing cost. The utility model is convenient to operate. The utility model can safely perform 360-degree rotary hoisting such that it can conveniently hoist cast-in-situ bridge crash barriers with hanging edges.
Description
Technical field
The utility model relates to the bridge construction equipment technical field, concretely, relates to the lifting appliance that is used for bridge construction process.
Background technology
Domestic bridge guard rail can be divided into three kinds according to profile mode difference at present, is respectively: common sitting posture crash barrier, band is hung cast-in-place crash barrier of eaves and prefabricated installation link plate crash barrier.
Wherein, it is linear poor that common sitting posture crash barrier has outward appearance, and rainwater is prone to cross flow to beam body, influences the shortcoming of beam body durability.
It is big that prefabricated installation link plate crash barrier has the welded and installed mass discrepancy, and whole impression effect is general, easily because problems of welded quality is buried shortcomings such as potential safety hazard.
Along with people's is to the improve day by day of esthetic requirement, and former common sitting posture crash barrier can not satisfy the aesthetic needs of people day by day, and the Collison fence for bridge that welded and installed band link plate or direct cast-in-place band are hung eaves arises at the historic moment.
Cast-in-place Collison fence for bridge difficulty of construction is big but band is hung eaves; In the lifting process, need and will be rotated and move installation with hanging the cast-in-place Collison fence for bridge of eaves, there is not supporting construction equipment at present; A lot of units in charge of construction can not accomplish construction because technology is immature; Part unit adopts small crane organizing construction, has the mechanical equipment expense and has high input, and safety does not have the shortcoming that ensures.
Summary of the invention
The utility model technical matters to be solved is the technical deficiency to above-mentioned existence, provides a kind of simple in structure, easy to use, can play the loop wheel machine that suspender belt is hung the cast-in-place Collison fence for bridge of eaves fast.
For solving the problems of the technologies described above, the technical scheme of the utility model is following: a kind of loop wheel machine, include dolly, and suspension bracket is installed on the dolly; Drag-line and hook is characterized in that: described suspension bracket is made up of base and support, and support has included suspension rod; Strut bar and digonal link wherein play suspension rod and tilt to the suspension hook direction, and strut bar is a vertical direction; Surround del with playing suspension rod, digonal link is held strut bar in the side, is provided with the rotational support wheel in the middle of the described base; Base can freely rotate on dolly with the rotational support wheel, one side have cantilever, cantilever to be provided with clump weight and motor with in the opposite direction the extending of suspension hook on the base.
In such scheme, roller is equipped with in said dolly bottom, and roller has roller shaft, can be in the arbitrarily angled rotation of horizontal surface.
In such scheme, described support is welded by angle steel, and the centre is welded with the support floor, and a top of the trellis is equipped with fixed pulley, and fixed pulley is at least two, is separately positioned on the edge of cantilever tip both sides.
In such scheme, described drag-line adopts the steel rope of 6 * 19 specifications, and drag-line one end fixing wound and passes the fixed pulley on the support on motor, and the drag-line other end is a movable end, overhangs the suspension bracket below.
The principle of the utility model is; Employing can 360 the suspension bracket of degree rotation lift by crane, suspension bracket is installed on the dolly, can move freely; Therefore can carry out the angle and the position of manual control suspension bracket, can install with the lifting of hanging the cast-in-place Collison fence for bridge of eaves easily.
The beneficial effect of the utility model is: simple in structure, easy to operate, low cost of manufacture, can safety carry out 360 degree rotation liftings, therefore can be easily with the lifting of hanging the cast-in-place Collison fence for bridge of eaves.
