Description

Technical Field

[0001] The utility model belongs to the technical field of travel push rods, in particular to a crane travel push rod with an anti-sway structure. Background Art

[0002] The prior art discloses an unmanned bridge crane simulation test bench that can realize automatic trajectory planning (see the attached manual for details). Figure 5 ), the travel push rod on it may shake during use, mainly due to unreasonable structural design and material selection, which makes the push rod unable to maintain sufficient stability when carrying heavy objects. For example, the fitting clearance between the push rod and the slide rail is too large, or the rigidity of the push rod itself is insufficient, which will cause excessive vibration and shaking during the stroke. These shakes not only affect the operating accuracy of the crane, but may also cause the heavy objects to swing, increasing the risk to the operator. For these problems, conventional solutions include increasing the rigidity of the push rod, reducing the gap, and optimizing the lubrication system to ensure smooth movement between the push rod and the slide rail. However, the implementation of these methods often faces some disadvantages. First, enhancing the rigidity of the push rod may increase its weight, which in turn affects the load capacity and flexibility of the entire crane, especially in operations that require high-frequency movement. An overly heavy push rod will reduce work efficiency. Therefore, we hope to design a welding equipment with a new structure to solve this problem. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of the present invention is to provide a crane travel push rod with an anti-sway structure to solve the problems raised in the above background technology.

[0004] The utility model is achieved through the following technical solutions: a crane travel push rod with an anti-sway structure, comprising: a push rod body and a protective assembly, wherein the push rod body is fixed to the lower side of the crane body, and a protective assembly for fixing the push rod body is fixed to the lower end of the push rod body, wherein the protective assembly comprises a first fixing seat, a second fixing seat, a first transmission rod, and a second transmission rod;

[0005] The upper edge of the fixing seat is hinged with a plurality of transmission rods 1 distributed in a ring structure, and the lower edge of the fixing seat is hinged with a plurality of transmission rods 2 distributed in a ring structure;

[0006] The upper ends of the plurality of transmission rods are movably connected to the lower sides of the plurality of transmission rods, and the lower side of each transmission rod is hinged with an elastic member.

[0007] As a preferred embodiment, a plurality of articulated seats 1 for articulating the transmission rod 1 are welded on the upper edge of the fixed seat 1, and the number and distribution positions of the articulated seats 1 match the number and distribution positions of the transmission rod 1. In actual use, the fixed seat 1 and the fixed seat 2 are respectively fixed on the upper outer wall of the push rod body, and the fixed seat 1 is placed directly below the fixed seat 2, which serves the purpose of fixing and limiting the push rod body.

[0008] As a preferred embodiment, a plurality of hinged seats 2 for hingedly connecting transmission rods 2 are welded to the lower edge of the second fixing seat, and the number and distribution positions of the second hinged seats match the number and distribution positions of the second transmission rods.

[0009] As a preferred embodiment, the number and distribution position of the articulated seat 1 matches the number and distribution position of the articulated seat 2, and the number and distribution position of the transmission rod 1 matches the number and distribution position of the transmission rod 2.

[0010] As a preferred embodiment, a sliding groove is formed through the lower side of each of the transmission rods from left to right, and the lower end of each of the sliding grooves is fixedly connected to the lower end of a spring.

[0011] As a preferred embodiment, a rectangular block is fixed to the upper end of each transmission rod by a bolt, the rectangular block is slidably installed inside the upper side of the sliding groove, and the lower end of the rectangular block is fixedly connected to the upper end of spring one.

[0012] As a preferred embodiment, the number and distribution position of the elastic members match the number and distribution position of the transmission rod 2, and the elastic member includes a spring 2 and a telescopic rod, and the spring 2 is movably mounted in the middle of the telescopic rod;

[0013] The telescopic rod includes an articulated joint 1, an articulated joint 2 and a pull rod. The upper side of the articulated joint 1 is threadedly connected to the lower end of the pull rod. The upper end of the pull rod is internally damped and slidably connected to the lower end of the articulated joint 2. The upper ends of multiple elastic parts are all damped and hinged with the crane body, which can cooperate with the transmission rod 1 and the transmission rod 2 to elastically limit the shaking of the push rod body, avoiding the problem of local deformation of the push rod body caused by direct rigid fixation when the lower end is subject to a larger shaking tendency.

[0014] After adopting the above technical solution, the beneficial effect of the utility model is as follows: by arranging a protective component on the upper side of the push rod body, in actual use, if the push rod body tends to tilt and shake, the push rod body will transmit this tendency to the protective component connected thereto, and since the fixing seat 1 is placed on the lower side of the fixing seat 2, the force applied to the fixing seat 1 is greater than the force applied to the fixing seat 2, which also makes the displacement distance of the push rod body axis of the fixing seat 1 larger than that in the initial state, and the upper edge of the fixing seat 1 is hinged with multiple transmission rods 1, and the upper end of each transmission rod 1 is movably connected to the lower side of a transmission rod 2, and since the lower end of the sliding groove is fixedly connected to the lower end of a spring 1, the upper end of each transmission rod 1 is connected by a screw The bolt is fixed with a rectangular block, which is slidably installed inside the upper side of the sliding groove, and the lower end of the rectangular block is fixedly connected to the upper end of the spring one. The offset of the fixed seat one will affect the multiple transmission rods one connected thereto. In the direction of the shaking trend, the transmission rod one at this position will squeeze or pull or squeeze the transmission rod two connected thereto. The spring one at the corresponding position, at the same time, the transmission rod two that receives the pulling or squeezing force will pull or squeeze the elastic member at the corresponding position. Under the coordinated action of the spring one and the elastic member, the force transmitted to the protective assembly by the push rod body is offset, thereby avoiding the problem of shaking of the push rod assembly during work, and greatly improving the stability of the push rod body during work;

[0015] The arrangement of transmission rod 1, transmission rod 2, spring 1 and elastic part is such that, in actual use, once the protective component is subjected to force, spring 1 and elastic part can cooperate with transmission rod 1 and transmission rod 2 to elastically limit the shaking of the push rod body (in use, multiple springs 1 and elastic parts are all in a pre-stressed state), avoiding the problem of local deformation of the push rod body caused by direct rigid fixation when the lower end is subjected to a large shaking tendency.
