Description

Technical Field

[0001] This utility model relates to the field of excavator technology, and more specifically, to a reinforced stick for an excavator. Background Technology

[0002] An excavator is an earthmoving machine that uses a bucket to dig materials and load them into transport vehicles or unload them into a stockpile. It consists of a power unit, working device, slewing mechanism, operating mechanism, transmission mechanism and traveling mechanism, and is widely used in construction, road construction, hydropower and mining.

[0003] A reinforced stick for excavators is a specially designed or modified stick designed to improve its strength, durability, and wear resistance. Specifically, it refers to the long arm on the excavator that connects to the bucket, called the stick. The stick is one of the main load-bearing components of the excavator and needs to have sufficient strength. Existing mechanical sticks are generally symmetrical, of equal width, and integrally enclosed box-shaped welded components.

[0004] During excavation operations, the reinforced stick of the excavator often comes into direct contact with hard materials such as rocks and ores. These materials have high hardness and impact force, which can easily cause impacts to the reinforced stick of the excavator. After being impacted, the reinforced stick of the excavator may undergo local or overall bending, twisting and other structural deformations, resulting in a decrease in its strength and rigidity, making it unable to continue to withstand normal working loads, thus shortening its service life.

[0005] Therefore, in order to solve the above-mentioned technical problems, this application proposes a reinforced stick for an excavator. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a reinforced stick for excavators.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a reinforced stick for an excavator, comprising a stick and a protective assembly mounted on the stick. The protective assembly includes an anti-collision plate. The anti-collision plate is mounted on the stick, and a buffer pad is mounted on the anti-collision plate. Multiple springs A are evenly and equidistantly mounted on the anti-collision plate. The end of each spring A furthest from the anti-collision plate passes through the buffer pad and is connected to a support plate. Sliding rods are symmetrically mounted on the anti-collision plate. A baffle is mounted on the end of each sliding rod furthest from the anti-collision plate. Both sliding rods pass through the support plate. The support plate is located between the baffle and the anti-collision plate and can slide... The rod slides vertically. Support frames are evenly and equidistantly mounted through the support plate. Each support frame has a limit plate installed at one end outside the support plate, and an annular plate installed at one end inside the support plate. Rolling balls are rolled at one end outside the support plate, and each end of the support frame is connected to the inside of the support plate by a spring B. Multiple symmetrical stabilizing rods are mounted through the rod. The two ends of each stabilizing rod are respectively installed on the upper and lower surfaces inside the support plate. Each annular plate can slide vertically on each stabilizing rod it is on.

[0008] Preferably, each of the rolling balls protrudes from the support frame, the dimensions of each annular plate and the limiting plate are larger than the support frame, and the dimensions of each baffle are larger than the sliding rod. This allows hard materials to connect with each rolling ball immediately, while also ensuring that the support frame remains on the support plate and that the support plate remains on the sliding rod.

[0009] Preferably, a support block is installed at one end of the stick, and the support block has a pin groove to facilitate the connection of the bucket.

[0010] Preferably, a connecting block is mirror-mounted at the end of the stick away from the support block, which facilitates connection with the excavator boom.

[0011] Preferably, a base is mirror-mounted on the boom to facilitate the connection of the hydraulic rod and ensure the stability of the hydraulic rod's operation.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. In this utility model, through the protective component set on the boom, hard material will first come into contact with the rolling balls on each support frame. Simultaneously, the hard material will compress each rolling ball upon contact. Because the surface of the hard material is uneven, the pressure on each rolling ball will vary. When the hard material compresses each rolling ball, this pressure will be transmitted through each rolling ball to its corresponding support frame. Then, each support frame will slide inwards to varying degrees, compressing the spring B connected to each support frame. This compression of spring B reduces the impact force of the hard material on the boom. The material will compress the support plate, which will then slide on the two slide bars toward the anti-collision pad. When the support plate slides, each evenly distributed spring A will be compressed to further absorb the impact force of the hard material on the stick. When the impact force is transmitted to the anti-collision plate and the buffer pad through each spring A, the buffer pad will also absorb part of the impact force, thereby preventing the hard material from directly contacting the stick. This solves the problem in the background technology that the reinforced stick of the excavator may undergo local or overall bending, twisting and other structural deformations after being impacted, resulting in a decrease in its strength and rigidity, making it unable to continue to withstand normal working loads, thus shortening its service life.

[0014] 2. In this utility model, by setting rolling balls on each support frame, when a hard material comes into contact with each rolling ball, the hard material will form rolling friction on the rolling ball. The coefficient of rolling friction is much lower than that of sliding friction, so the friction force can be significantly reduced, thereby improving the working efficiency. At the same time, the rolling balls can evenly distribute the pressure acting on the inner surface of the boom, avoiding local stress concentration. This evenly distributed pressure helps to reduce the wear and deformation of the boom and extend its service life. Attached Figure Description

[0020] like Figure 1-3 As shown, this utility model provides a reinforced stick for an excavator, including a stick 1 and a protective component 6 mounted on the stick 1. This component ensures that hard materials first contact the rolling balls 609 on each support frame 607. Simultaneously, the hard material compresses each rolling ball 609 upon contact. Because the surface of the hard material is uneven, the pressure on each rolling ball 609 will vary. When the hard material compresses each rolling ball 609, this pressure is transmitted through each rolling ball to its corresponding support frame 607. Then, each support frame 607 will slide inwards to varying degrees into the support plate 604. At this time, the spring B61 ​​connected to each support frame 607... The springs 0 will be compressed. At this time, the compression of each spring B610 can reduce the impact force of hard materials on the boom 1. At the same time, the hard materials will squeeze the support plate 604. The support plate 604 will slide on the two slide rods 605 towards the anti-collision pad. When the support plate 604 slides, each evenly distributed spring A603 will be compressed to further absorb the impact force of hard materials on the boom 1. When the impact force is transmitted to the anti-collision plate 601 and the buffer pad 602 through each spring A603, the buffer pad 602 will also absorb part of the impact force to avoid direct contact between hard materials and the boom 1. This can effectively reduce wear and damage caused by friction and impact, thereby increasing service life.

[0021] The protective component 6 includes an anti-collision plate 601, which is installed on the boom 1 to prevent collisions. A buffer pad 602 is installed on the anti-collision plate 601 to absorb the impact force of hard materials on the boom 1. Multiple springs A603 are evenly spaced on the anti-collision plate 601 for cushioning. The end of each spring A603 furthest from the anti-collision plate 601 extends through the buffer pad 602 and is connected to a support plate 604 for support. Sliding rods 605 are symmetrically installed on the anti-collision plate 601 to ensure stability when the support plate 604 slides. A baffle 606 is installed on the end of each sliding rod 605 furthest from the anti-collision plate 601 to prevent the support plate 604 from detaching from the sliding rod. The function of 605 is to limit the movement of the support plate 604 by having two sliding rods 605 pass through it. The support plate 604 is located between the baffle 606 and the anti-collision plate 601 and can slide vertically on the sliding rods 605. The support plate 604 is evenly and equidistantly slidably mounted on the support plate 604 to support the rolling ball 609. Each support frame 607 is equipped with a limit plate 608 at one end outside the support plate 604 to prevent the support frame 607 from completely entering the support plate 604. Each support frame 607 is equipped with an annular plate 611 at one end inside the support plate 604 to prevent the support frame 607 from completely detaching from the support plate 604.

[0022] Each support frame 607 has rolling balls 609 rolled on one end outside the support plate 604. When a hard material comes into contact with each rolling ball 609, the hard material will form rolling friction on the rolling ball 609. The coefficient of rolling friction is much lower than that of sliding friction, so it can significantly reduce friction and improve working efficiency. At the same time, the rolling balls 609 can evenly distribute the pressure acting on the inner surface of the stick 1, avoiding local stress concentration. This evenly distributed pressure helps to reduce the wear and deformation of the stick 1 and extend its service life.

[0023] Furthermore, each support frame 607 is connected to the support plate 604 at one end via a spring B610, which serves to buffer and support the support frame 607. Multiple symmetrical stabilizing rods 612 are installed through each annular plate 611, with each stabilizing rod 612 having its two ends installed on the upper and lower surfaces of the support plate 604 respectively. Each annular plate 611 can slide vertically on each stabilizing rod 612 it is positioned on, which serves to ensure the stability of the support frame 607 during vertical sliding.

[0024] Each ball bearing 609 protrudes from its supporting frame 607 to facilitate contact between hard materials and the ball bearing 609. The dimensions of each annular plate 611 and limiting plate 608 are larger than those of the supporting frame 607 to prevent the supporting frame 607 from completely entering or leaving the supporting plate 604. The dimensions of each baffle 606 are larger than those of the slide bar 605 to limit the supporting plate 604 on the slide bar 605 and prevent the supporting plate 604 from leaving the slide bar 605.

[0025] A support block 2 is installed at one end of the boom 1, which is used for connection. The support block 2 has a pin groove 3, which is used to realize the function of garbage bucket.

[0026] A connecting block 4 is mirror-mounted on the end of the boom 1 away from the support block 2, which is used to connect with the excavator boom.

[0027] A base 5 is mounted on the boom 1 in a mirror image, which is used to connect the hydraulic rod.

[0028] Working principle: When the excavated hard material collides with the boom 1, the hard material will first contact the rolling balls 609 on each support frame 607, thus avoiding direct contact between the boom 1 and the hard material. Simultaneously, the hard material will compress each rolling ball 609 upon contact. Because the surface of the hard material is uneven, the pressure on each rolling ball 609 will vary. This pressure is transmitted through each rolling ball 609 to the support frame 607, causing each support frame 607 to slide inwards to varying degrees into the support plate 604. At this time, the spring B connected to each support frame 607... 610 will be compressed. At this time, the compression of each spring B610 can reduce the impact force of hard materials on the boom 1. At the same time, the hard materials will squeeze the support plate 604. The support plate 604 will slide on the two slide rods 605 towards the anti-collision pad. When the support plate 604 slides, each evenly distributed spring A603 will be compressed to further absorb the impact force of hard materials on the boom 1. When the impact force is transmitted to the anti-collision plate 601 and the buffer pad 602 through each spring A603, the buffer pad 602 will also absorb part of the impact force, thereby avoiding direct contact between hard materials and the boom 1. This can effectively reduce wear and damage caused by friction and impact, thereby increasing service life.
