Description

Technical Field

[0001] This utility model relates to the field of excavator boom technology, specifically to a riveted and welded reinforced structure for an excavator boom that resists deformation. Background Technology

[0002] The excavator stick structure is a working device that connects the excavator stick and the bucket. This structure includes the stick front end, the housing, and the stick rear end.

[0003] When in use, the stick does not have a reinforcing function, which can easily lead to cracking of the stick when the excavator is working under high load, thus affecting the normal operation of the excavator and even causing safety accidents. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a riveted and welded reinforced structure for the stick of an anti-deformation excavator, which has the advantages of increasing the strength of the stick and solving the problem of the stick being prone to cracking during use.

[0005] This utility model discloses a riveted and welded reinforced structure for an anti-deformation excavator stick, comprising a stick body with reinforcing components on both sides. Each reinforcing component includes two L-shaped reinforcing plates, one side of which is welded to the stick body. Reinforcing rods are welded to the top and bottom of corresponding sides of the two L-shaped reinforcing plates. The contact surfaces of one end of the four reinforcing rods are fixedly connected by welding. Reinforcing ribs are welded to corresponding sides of the two reinforcing rods. The outer side of the L-shaped reinforcing plates is fixedly connected to the stick body via support rods. When the stick body is in use, the force on the stick body can be transmitted to the L-shaped reinforcing plates, which in turn transmit the force to the reinforcing rods, which then transmit the force to the reinforcing ribs. The L-shaped reinforcing plates can also transmit the force to the support rods. This allows the force on the stick body to be transferred to the reinforcing components during use. The ultra-durable welding design of the reinforcing components prevents the stick from cracking under high loads, thus avoiding disruption to the excavator's normal operation and potentially causing safety accidents.

[0006] The present invention relates to a deformation-resistant excavator boom riveting and welding reinforcement structure, wherein both ends of the support rod are fixedly connected to the L-reinforcing plate and the boom body by welding, and one end of the support rod is located at the center of the outer side of the L-reinforcing plate.

[0007] The present invention relates to a deformation-resistant excavator boom riveting and welding reinforcement structure, wherein the inner side of the reinforcing rod is provided with three reinforcing ribs, and the three reinforcing ribs are welded at equal intervals on the corresponding sides of the two reinforcing rods.

[0008] This utility model discloses a riveted and welded reinforcement structure for the boom of an anti-deformation excavator. The top and bottom of the inner cavity of the L-shaped reinforcing plate are connected to the main body of the boom by countersunk rivets. The two countersunk rivets are arranged symmetrically about the L-shaped reinforcing plate. This utility model can fix and stabilize the L-shaped reinforcing plate by using countersunk rivets, avoiding the situation where the L-shaped reinforcing plate becomes loose during use, thus preventing the L-shaped reinforcing plate from having poor performance.

[0009] The present invention relates to a deformation-resistant excavator boom riveting and welding reinforcement structure, wherein the mounting holes of the countersunk rivets are machined and formed after the boom body is welded, the hole diameter tolerance is controlled within H8 grade, and the hole periphery is sealed after riveting.

[0010] The present invention relates to a riveted and welded reinforced structure for the boom of an anti-deformation excavator, wherein the components within the reinforced assembly are made of high-strength alloy steel plates, the yield strength of which is not less than 1.3 times that of the main body material of the boom.

[0011] This utility model discloses a riveted and welded reinforced structure for the anti-deformation excavator boom. The right side of the top of the boom body is provided with seven reinforcing strips, which are fixed to the boom body at equal intervals by welding. The reinforcing strips can strengthen the concentrated stress points of the boom body during use, thus improving the performance of the boom body and preventing cracking at the concentrated stress points during use.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. When the boom body is in use, the force on the boom body can be transmitted to the L-shaped reinforcing plate, which in turn transmits the force to the reinforcing rod, which in turn transmits the force to the reinforcing rib, and the L-shaped reinforcing plate also transmits the force to the support rod. In this way, when the boom body is in use, the force points of the boom body can be transmitted to the reinforcing components. Through the ultra-durable welding design of the reinforcing components, the boom cracking phenomenon can be avoided when the excavator is working under high load, which would affect the normal operation of the excavator and even cause safety accidents.

[0014] 2. This utility model uses countersunk rivets to fix and stabilize the L-shaped reinforcing plate, thus preventing it from becoming loose during use and thus affecting its performance.

[0015] The reinforcing strips strengthen the concentrated stress points of the boom body during use, resulting in better performance and preventing cracking at these points. Attached Figure Description

However, it should be understood that these practical details should not be used to limit this utility model. That is, in some embodiments of this utility model, these practical details are not essential. In addition, for the sake of simplicity, some conventional structures and components will be shown in the drawings in a simple schematic manner.

[0021] Please see Figure 1-2 This utility model discloses a riveted and welded reinforced structure for an anti-deformation excavator boom, comprising a boom body 1, with reinforcing components 3 on both sides of the boom body 1. Each reinforcing component 3 includes two L-shaped reinforcing plates 301, one side of which is welded to the boom body 1. Reinforcing rods 304 are welded to the top and bottom of corresponding sides of the two L-shaped reinforcing plates 301. The contact surfaces of one end of the four reinforcing rods 304 are fixedly connected by welding. Reinforcing ribs 305 are welded to corresponding sides of the two reinforcing rods 304. The outer side of the L-shaped reinforcing plates 301 is fixedly connected to the boom body 1 by support rods 302. When the new boom body 1 is in use, the force on the boom body 1 can be transmitted to the L-reinforcing plate 301, which in turn transmits the force to the reinforcing rod 304, which in turn transmits the force to the reinforcing rib 305. The L-reinforcing plate 301 can also transmit the force to the support rod 302. In this way, when the boom body 1 is in use, the force points of the boom body 1 can be transmitted to the reinforcing component 3. Through the ultra-durable welding design of the reinforcing component 3, the boom cracking phenomenon can be avoided when the excavator is working under high load, which would affect the normal operation of the excavator and even cause safety accidents.

[0022] Both ends of the support rod 302 are fixedly connected to the L-reinforcing plate 301 and the main body of the stick 1 by welding, and one end of the support rod 302 is located at the center of the outer side of the L-reinforcing plate 301.

[0023] The inner side of the reinforcing rod 304 is provided with three reinforcing ribs 305, and the three reinforcing ribs 305 are welded at equal intervals on the corresponding side of the two reinforcing rods 304.

[0024] The top and bottom of the inner cavity of the L-reinforcing plate 301 are connected to the main body 1 of the boom by countersunk rivets 303. The two countersunk rivets 303 are arranged symmetrically about the L-reinforcing plate 301. The countersunk rivets 303 can fix and stabilize the L-reinforcing plate 301, avoiding the L-reinforcing plate 301 from loosening during use, which would lead to poor performance of the L-reinforcing plate 301.

[0025] The mounting holes for countersunk rivets 303 are machined and formed after welding the main body 1 of the boom. The hole diameter tolerance is controlled within H8 grade. After riveting, the hole is sealed.

[0026] The components within the reinforcing assembly 3 are made of high-strength alloy steel plates, with a yield strength not less than 1.3 times that of the main body of the boom 1.

[0027] The top right side of the boom body 1 is provided with seven reinforcing strips 2, and the seven reinforcing strips 2 are fixed to the boom body 1 at equal intervals by welding. The reinforcing strips 2 can strengthen the concentrated stress points of the boom body 1 when it is in use, so that the boom body 1 is more effective when in use and avoids the situation where the concentrated stress points of the boom body 1 are prone to cracking.

[0028] When using this utility model: When the stick body 1 is in use, the force on the stick body 1 can be transmitted to the L-reinforcing plate 301, the force can be transmitted to the reinforcing rod 304 through the L-reinforcing plate 301, the force can be transmitted to the reinforcing rib 305 through the reinforcing rod 304, and the force can also be transmitted to the support rod 302 through the L-reinforcing plate 301. In this way, when the stick body 1 is in use, the force point of the stick body 1 can be transmitted to the reinforcing component 3. Through the ultra-durable welding design of the reinforcing component 3, the stick cracking phenomenon can be avoided when the excavator is working under high load, thereby affecting the normal operation of the excavator and even causing safety accidents.
