Description

Four-point lifting rotating lifting beam bascule

Technical field

Crane technical field is the utility model is related to, specifically, is related to a kind of four-point lifting rotating lifting beam bascule.

Background technology

The upper end of the four-point lifting rotation hanging beam of crane is provided with four suspension centres, and each suspension centre is fixed with hanging beam cunning Wheel, is also correspondingly provided with four trolley frame pulleys, the corresponding hanging beam pulley in position, trolley frame pulley on the trolley frame of crane On be wound with lift heavy steel wire rope, one end of lift heavy steel wire rope is fixedly connected with trolley frame, and the other end of lift heavy steel wire rope is fixed on On reel, during spool turns, winding or release lift heavy steel wire rope, hanging beam raising or decline are rotated, and then drive suspender to rise Rise or decline.To make the horizontal raising of suspender, then it is flat better to rotate hanging beam water crossing, four lift heavy steel wire rope stress it is more uniform more It is good.

But due to dolly installation accuracy, lift heavy steel wire rope Adjustment precision, the actual work of four lift heavy steel wire ropes It is different in size to make length, it is difficult to ensure that rotation hanging beam is horizontal, the discontinuity of four lift heavy steel wire ropes.In addition, dolly is installed Precision, lift heavy steel wire rope Adjustment precision have very high requirement, not only increase the labor intensity of staff, and be difficult to install It is adjusted in place, reduces operating efficiency.

The content of the invention

Technical problem to be solved in the utility model is：One kind is provided and can be allowed and rotates the horizontal raising of hanging beam, steel wire rope The four-point lifting rotating lifting beam bascule of uniform force.

In order to solve the above technical problems, the technical solution of the utility model is：

Four-point lifting rotating lifting beam bascule includes：It is single that the four-point lifting rotating lifting beam bascule includes two balances Member, each balancing unit include:Two balance oscillating arms, each balance oscillating arm are provided with three tie points, are respectively First tie point, the second tie point and the 3rd tie point, first tie point, second tie point and the 3rd connection Not on the same line, the 3rd tie point of the balance oscillating arm is used to connect lift heavy steel wire rope point, and two bearings are described First tie point of balance oscillating arm is hinged with a corresponding bearing, and balanced connecting rod, the balanced connecting rod is connected to Between second tie point of two balance oscillating arms.

Preferably, the balance oscillating arm is L-shaped, and first tie point is located at the corner of the balance oscillating arm of L-shaped, institute State the end that the second tie point, the 3rd tie point are located at the balance oscillating arm of L-shaped respectively.

After employing above-mentioned technical proposal, the beneficial effects of the utility model are：

Because balance oscillating arm is provided with the first tie point, the second tie point and the 3rd tie point not on the same line, First tie point of two balance oscillating arms is hingedly connected on a bearing, is passed through between the second tie point of two balance oscillating arms Balanced connecting rod connects；When rotation hanging beam is in not horizontality, the stress of the lift heavy steel wire rope in same balancing unit differs Cause, then the big lift heavy steel wire rope of stress pulls connected balance oscillating arm rotation, and the balance oscillating arm is pulled by balanced connecting rod Another balance oscillating arm, another balance oscillating arm pull the small lift heavy steel wire rope of stress so that in same balancing unit with two The suspension centre that lift heavy steel wire rope is connected is horizontal, two lift heavy steel wire rope uniform forces, is hung by two sets of balancing unit balance rotatings Four suspension centres of beam so that the rotation horizontal raising of hanging beam, four lift heavy steel wire rope uniform forces.

Embodiment

In order that the purpose of this utility model, technical scheme and advantage are more clearly understood, below in conjunction with accompanying drawing and implementation Example, the utility model is further elaborated.It should be appreciated that specific embodiment described herein is only explaining The utility model, and it is not used in restriction the utility model.

As shown in Fig. 2 a kind of four-point lifting rotating lifting beam bascule, including：Two balancing units.

As Fig. 1 and Fig. 2 are jointly shown, each balancing unit includes two balance oscillating arms, 1, two bearing 4 and one Balance rope 2.

Balance oscillating arm 1 is L-shaped, and balance oscillating arm 1 is provided with three tie points not on the same line, wherein, first Tie point is located at the corner of L-shaped balance oscillating arm 1, and first tie point is pin joint, and balance oscillating arm 1 is rotated by hinge 3 It is connected on bearing 4, the second tie point, the 3rd tie point are respectively arranged on the both ends of the balance oscillating arm 1 of L-shaped.

Balance rope 2 is connected between the second tie point of two balance oscillating arms 1, and balance rope 2 can also be by even Bar replaces.

As shown in Fig. 2 during crane hoisting weight, four bearings 4 in two sets of balancing units are fixed on the small of crane On vehicle frame, four lift heavy steel wire ropes 8 in two sets of balancing units are connected by four sets of assembly pulleys with rotation hanging beam respectively.

Often set pulley is organized including two two hanging beam pulleys 6 being fixed on rotation hanging beam, is fixed on trolley frame Trolley frame pulley 5, four lift heavy steel wire ropes 8 bypass a hanging beam pulley 6, trolley frame pulley 5 and another hanging beam successively respectively Pulley 6, one end of lift heavy steel wire rope 8 are fixedly connected with rotation hanging beam, and the other end of lift heavy steel wire rope 8 is fixedly connected with reel 7.

During the rotation of reel 7, winding lift heavy steel wire rope 8, lift heavy steel wire rope 8 pulls hanging beam pulley 6, drives rotation hanging beam and hangs It is hung on the suspender rotated on hanging beam, weight raising.In same balancing unit, if the actual work of a certain bar lift heavy steel wire rope 8 Make that length is long, then rotate hanging beam connect the lift heavy steel wire rope 8 hoisting point position it is low, the stress of the lift heavy steel wire rope 8 is less than another The stress of one lift heavy steel wire rope 8, then another lift heavy steel wire rope 8 pull downward on connected balance oscillating arm 1, the balance wheel Arm 1 pulls another balance oscillating arm 1 by balance rope 2, and another balance oscillating arm 1 pulls up the small lift heavy steel wire of stress Rope 8 so that rotation hanging beam is horizontal, two uniform forces of lift heavy steel wire rope 8.

Two balance oscillating arms, 1, two bearing 4 and a balance rope 2 are collectively forming quadric chain, and bascule fills When point make use of rotation hanging beam unhorizontal, the stress of lift heavy steel wire rope 8 is inconsistent, and balance oscillating arm 1 rotates automatic compensation, to allow rotation Turn the horizontal raising of hanging beam, four uniform forces of lift heavy steel wire rope 8, so as to reduce dolly installation accuracy, steel wire rope Adjustment precision Requirement, reduce the labor intensity of staff, improve operating efficiency.

Citing described above for the utility model preferred forms, wherein the part do not addressed in detail is this area The common knowledge of those of ordinary skill.The scope of protection of the utility model is defined by the content of claim, any to be based on this reality The equivalent transformation carried out with new technical inspiration, also within the scope of protection of the utility model.
