Abstract
The utility model relates to a mechanical grab-bucket lower bolster structure, which comprises a lower pulley holder and a crossbeam, and is characterized in that the lower part of the lower pulley holder is provided with a mounting shaft hole, the upper part of the crossbeam is provided with a connection shaft hole corresponding to the mounting shaft hole, the lower pulley holder is connected with the crossbeam through a connection shaft, and the lower pulley holder can rotate relatively to the crossbeam. The crossbeam can rotate relatively to the lower pulley holder, so the stress of a switching wire cable is uniform, and the grab bucket can be ensured to have better balance. When the grab bucket grabs and lifts the cargoes, the switching wire cable is free from being separated from a pulley groove and facilitating the deformation of a wire cable protection hood, so the switching wire cable can be prevented from being collided with the wire cable protection hood; moreover the lower pulley holder and the crossbeam, which are hinged with each other, are free from having the stress and straining which are produced in the welding, so the strength of the base metal can be ensured, andthe base metal can be prevented from being torn; and during the grabbing process of the grab bucket, the stress of all parts of the grab bucket are scattered, so the grab bucket is difficult to be deformed, the service life is effectively prolonged, and the safety coefficient is improved.
Description
Technical field
The utility model belongs to the loading-unload machine equipment technical field, relates to a kind of grab bucket link, specifically is a kind of machinery grab bucket through beam structure.
Background technology
In industries such as the mechanical, electrical factory in harbour port, destructor plant, steel mill, the mechanical orange-peel bucket that is used for the lifting of four ropes is a kind of loading-unload machine that is widely used, the through beam crossbeam of the mechanical orange-peel bucket of existing installation and downslide wheel seat all are weld togethers, be integral structure, and welding the time can produce sizable stress and strain, reduce the intensity of mother metal, when moment, momentum was excessive, tear at downslide wheel seat and crossbeam position of weld easily; Grab bucket makes single bucket lobe stressed too concentrated in the extracting process, causes the distortion of bucket lobe; When grab bucket is grasped goods under the inclination situation,, open and close steel rope and can break away from pulley groove, make cable wire protective case stress deformation owing to be subjected to force unbalance; And opening and closing steel rope and the cable wire protective case rubs for a long time, there is certain potential safety hazard in the lost of life; Han Jie crossbeam does not have commutativity simultaneously, narrow application range.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of machinery grab bucket through beam structure is provided, adopt the machinery grab bucket alerting ability and the safety of this structure to strengthen greatly, safeguard and the maintenance load attenuating, effectively cost-cutting, raising work efficiency.
The purpose of this utility model realizes by following technical scheme, described machinery grab bucket through beam structure comprises downslide wheel seat and crossbeam, it is characterized in that: described downslide wheel seat bottom is provided with installation axle hole, described crossbeam top is provided with corresponding connection axis hole, the downslide wheel seat is connected with adapter shaft with crossbeam, and can relatively rotate.
Installation axle hole two ends on the described downslide wheel seat are provided with bearing seat, and adapter shaft is assemblied in the installation axle hole by bearing seat; Described adapter shaft two ends are fixed with clamp, and described clamp is fixedly mounted on the side plate both sides on the crossbeam.
As further improvement of the utility model, described adapter shaft two ends offer the axial oil nozzle and the oilhole of lateral direction penetrating, and oil nozzle is inner to be interconnected with oilhole.
The utility model compared with prior art, because crossbeam and downslide wheel seat can relatively rotate, it is stressed evenly to open and close steel rope, a good gravity balance can keep grabbing bucket, when grab bucket is grasped goods and is promoted, the downslide wheel seat remains vertically, opens and closes steel rope and can not break away from pulley groove and make the distortion of cable wire protective case, and avoid steel rope and the friction of cable wire protective case; And the downslide wheel seat that is hinged and the crossbeam stress and strain that do not exist the welding back to produce, can guarantee the intensity of mother metal to obtain enough bufferings when grasping bulk goods, avoid tearing; In the grab bucket extracting process, all bucket lobe stress disperse, and are not yielding, effectively increase the service life, and improve safety factor.
Description of drawings
Fig. 1 is the utility model machinery grab bucket through beam structure front elevation.
Fig. 2 is the utility model machinery grab bucket through beam structure side view.
Fig. 3 is the cut-away view of downslide wheel seat and crossbeam connecting portion among Fig. 1.
The specific embodiment
The invention will be further described below in conjunction with concrete drawings and Examples.
As shown in Figure 1 and Figure 2: described machinery grab bucket through beam structure comprises downslide wheel seat 1 and crossbeam 10, described downslide wheel seat 1 bottom is provided with installation axle hole 2, described crossbeam 10 tops are provided with corresponding connection axis hole 4, downslide wheel seat 1 is connected with crossbeam 10 usefulness adapter shafts 5, and downslide wheel seat 1 can be done freely rotating of certain angle with respect to crossbeam 9.
As shown in Figure 3, installation axle hole 2 two ends on the described downslide wheel seat 1 are provided with bearing seat, and adapter shaft 5 two ends bearing sets 3 also are assemblied in the installation axle hole 2 by bearing seat; Described adapter shaft 5 two ends are fixing with clamp 9, and described clamp 9 is fixedly mounted on side plate 11 both sides on the crossbeam 10 by bolt 8.
As shown in Figure 3, described adapter shaft 5 two ends offer the oilhole 7 of axial oil nozzle 6 and lateral direction penetrating, and oil nozzle 6 is inner to be interconnected with oilhole 7, after lubricating oil adds by oil nozzle 6, enter on the bearing 3 lubricate via the oilhole 7 of lateral direction penetrating.
In actual applications, when grab bucket is grasped goods and is promoted, described downslide wheel seat 1 will freely be rotated by force direction along steel rope, the downslide wheel seat is remained vertically, grab bucket keeps good gravity balance, it is stressed all the time evenly to open and close steel rope, can not break away from pulley groove or rubs with the cable wire protective case; Make the stressed dispersion of all bucket lobes in the grab bucket extracting process, can be well closed, and not yielding, effectively increase the service life, improve safety factor.
