Description

Technical Field

[0001] This utility model relates to the field of hydraulic shear support technology, and in particular to a hydraulic shear support reinforcement component. Background Technology

[0002] Hydraulic shears are mobile hydraulic devices mounted on the front of excavators for dismantling or shearing materials. A hydraulic shear is a tool that uses hydraulic principles for shearing operations. It mainly consists of an aluminum alloy shell, hot-rolled steel forged blades, a piston made of hot-rolled alloy steel, and a piston rod. The hydraulic shears are powered by a hydraulic system. When hydraulic fluid flows into the hydraulic cylinder, pressure is applied to the piston, thereby driving the opening and closing of the blades.

[0003] The support frame of the hydraulic shears is a crucial component of the entire product, positioned similarly to the waist and abdomen in the human body. When the hydraulic shears are in operation, the thrust output from the cylinder must be converted into shearing force on the target object by the blades, relying on the support provided by the frame.

[0004] In existing technologies, hydraulic shears often need to withstand significant shearing and impact forces during actual operation. Existing hydraulic shear supports have certain shortcomings in terms of structural strength and stability. For example, under prolonged and frequent high-intensity operations, some key components of the support are prone to deformation and cracking, affecting the normal use and shearing accuracy of the hydraulic shears. Furthermore, existing supports are not designed to fully consider the stress characteristics under different working conditions, making it difficult to provide reliable and stable support in complex and changing working environments. In addition, existing hydraulic shear supports have limited reinforcement methods, mostly relying on simply increasing material thickness or using ordinary connectors to improve strength. This not only increases the weight of the support but also fails to fundamentally solve the problems of insufficient strength and stability. With the widespread application of hydraulic shears in building demolition, metal recycling, and other fields, higher requirements are placed on the strength and stability of their supports. Therefore, there is an urgent need for a component that can effectively strengthen hydraulic shear supports to improve the working performance and service life of the hydraulic shears. Utility Model Content

[0005] The main objective of this invention is to provide a hydraulic shear support reinforcement assembly that can effectively solve the problems in the background art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A hydraulic shear support reinforcement assembly includes an upper connecting seat for the hydraulic shear. The bottom surface of the upper connecting seat is provided with a hydraulic shear support body, which is inverted U-shaped. The side wall of the hydraulic shear support body is provided with shaft holes for movably connecting a hydraulic cylinder and a blade. The hydraulic shear support body has a reinforcement mechanism inside, which includes an inner stiffening plate, node reinforcement blocks, and a reinforcing connecting crossbar. The inner stiffening plate is fixedly connected to the inner stiffening plate on both sides of the inner wall of the hydraulic shear support body. The node reinforcement blocks are fixedly connected to the inner stiffening plate through triangular stiffening blocks on the outer wall. The reinforcing connecting crossbar is fixedly connected between the symmetrical node reinforcement blocks through threaded connecting sleeves at both ends of the outer wall.

[0008] More preferably, the inner stiffening plate is composed of several transverse and longitudinal stiffening bars that are fixedly installed together in an interlaced manner, and the inner stiffening plates are fixedly installed on the inner two side walls of the hydraulic shear support body respectively.

[0009] More preferably, the node reinforcement block is hexagonal in shape, and triangular rib blocks are fixedly installed on the four sides of the outer wall of the node reinforcement block. The triangular rib blocks are fixedly installed at the node formed by the transverse ribs and the longitudinal ribs by insertion.

[0010] More preferably, a threaded short rod is fixedly installed on the inner wall of the node reinforcing block, and a positioning groove is provided on the outer wall of the threaded short rod.

[0011] More preferably, a set of symmetrical retaining rings are fixedly installed on the outer wall of the reinforcing connecting crossbar, and external threads are respectively opened at both ends of the outer side of the reinforcing connecting crossbar. Positioning blocks are fixedly installed on both ends of the reinforcing connecting crossbar, and the positioning blocks are inserted into the positioning grooves.

[0012] More preferably, the threaded connecting sleeve is threadedly connected to both the external thread and the threaded short rod.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] In this utility model, by setting a reinforcing mechanism inside the hydraulic shear support body, including internal stiffening plates, node reinforcing blocks, and reinforcing connecting crossbars, the overall structural strength of the hydraulic shear support body is effectively improved. The internal stiffening plates are composed of intersecting transverse and longitudinal stiffening bars, which are installed on both sides of the support body, greatly enhancing the rigidity of the side walls. This can better resist the shearing force and impact force generated during operation, reduce the risk of deformation and cracking in key parts, and effectively ensure the normal operation of the hydraulic shear and the accuracy of shearing.

[0015] Furthermore, the node reinforcement blocks are designed in a hexagonal shape, with triangular ribs on the four sides of their outer walls inserted into the node locations of the transverse and longitudinal ribs. This allows for targeted reinforcement at the nodes, effectively dispersing stress concentration points. This design fully considers the stress characteristics under different working conditions, enabling the support to rationally distribute stress and provide stable and reliable support even in complex and variable working environments, thus improving the adaptability and stability of the support.

[0016] Meanwhile, the reinforcing connecting crossbar is fixedly connected to the symmetrical node reinforcing blocks through the threaded connecting sleeves at both ends of the outer wall. The retaining ring, external thread, and positioning block on the reinforcing connecting crossbar cooperate with the threaded short rod and positioning groove on the node reinforcing block. This connection method not only makes the installation and disassembly process more convenient, but also ensures a stable connection between the reinforcing connecting crossbar and the node reinforcing block, further enhancing the stability and reliability of the entire reinforcing mechanism.

[0017] Therefore, unlike existing technologies that rely solely on increasing material thickness or using ordinary connectors to improve strength, this reinforcing component fundamentally improves the insufficient strength and stability of the support without significantly increasing its weight. This not only benefits the overall operational performance of the hydraulic shears but also reduces energy consumption, improves equipment efficiency, extends the service life of the hydraulic shears, and meets the demand for higher strength and stability of the hydraulic shear support body.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] like Figure 1 - Figure 7 As shown, a hydraulic shear support reinforcement assembly includes an upper hydraulic shear connecting seat 1. The bottom surface of the upper hydraulic shear connecting seat 1 is provided with a hydraulic shear support body 2, which is inverted U-shaped. The side wall of the hydraulic shear support body 2 is also provided with shaft holes 3 for movably connecting the hydraulic cylinder and the blade. The interior of the hydraulic shear support body 2 is provided with a reinforcement mechanism 4, which includes an inner stiffening plate 5, a node reinforcement block 8, and a reinforcement connecting crossbar 12. The inner stiffening plate 5 is fixedly connected to the two inner side walls of the hydraulic shear support body 2, and the node reinforcement block 8 is fixedly connected to the inner stiffening plate 5 through a triangular stiffening block 9 on the outer side wall. The reinforcement connecting crossbar 12 is fixedly connected between the symmetrical node reinforcement blocks 8 through threaded connecting sleeves 16 at both ends of the outer wall.

[0028] Example 1: As Figures 3-5 As shown, the inner stiffening plate 5 is composed of several intersecting and fixedly installed transverse stiffening bars 6 and longitudinal stiffening bars 7. The inner stiffening plate 5 is fixedly installed on the inner two side walls of the hydraulic shear support body 2. The inner stiffening plate 5 is composed of several intersecting and fixedly installed transverse stiffening bars 6 and longitudinal stiffening bars 7, forming a grid-like structural system. It is fixedly installed on the inner two side walls of the hydraulic shear support body 2. This intersecting stiffening bar distribution can form multiple mutually supporting force units on the side walls of the hydraulic shear support body 2. When the side walls are subjected to shear force and impact force, the force can be dispersed and transmitted through the stiffening bars, which enhances the strength and rigidity of the side walls of the hydraulic shear support body 2, improves the resistance of the side walls to external forces, effectively reduces the possibility of deformation and cracking of the side walls under long-term frequent high-intensity operation, ensures the structural stability and service life of the hydraulic shear support body 2, and thus ensures the normal use and shearing accuracy of the hydraulic shear.

[0029] Example 2: Figure 3 and Figure 6 As shown, the node reinforcement block 8 is hexagonal in shape, and triangular rib blocks 9 are fixedly installed on the four sides of the outer wall of the node reinforcement block 8. The triangular rib blocks 9 are fixedly installed at the node formed by the transverse ribs 6 and the longitudinal ribs 7 by insertion. Since the node is the place where the stress is concentrated in the inner stiffening plate 5, the triangular rib blocks 9 inserted at the node can disperse the stress at the node to the node reinforcement block 8, and then the node reinforcement block 8 can carry out more extensive stress transmission and dispersion, strengthen the node of the inner stiffening plate 5, effectively alleviate the stress concentration problem at the node, and further improve the overall strength and stability of the inner stiffening plate 5. This allows the hydraulic shear support body 2 to distribute stress more reasonably when subjected to complex and variable external forces, provide more reliable support, and enhance the adaptability of the hydraulic shear support body 2 under different working conditions.

[0030] Example 3: Figure 2 , Figure 3 , Figure 4 , Figure 6 and Figure 7 As shown, a threaded short rod 10 is fixedly installed on the inner wall of the node reinforcing block 8, and a positioning groove 11 is provided on the outer wall of the threaded short rod 10; a set of left and right symmetrical retaining rings 13 are fixedly installed on the outer wall of the reinforcing connecting crossbar 12, and external threads 14 are respectively provided at both ends of the reinforcing connecting crossbar 12; positioning blocks 15 are fixedly installed on both end walls of the reinforcing connecting crossbar 12, and the positioning blocks 15 are inserted into the positioning grooves 11; the threaded connecting sleeve 16 is threadedly connected to the external threads 14 and the threaded short rod 10 respectively.

[0031] The reinforcing crossbar 12 is placed between the symmetrical node reinforcing blocks 8 inside the hydraulic shear support body 2, and the positioning blocks 15 at both ends of the reinforcing crossbar 12 are inserted into the positioning grooves 11 opened on the threaded short rods 10 installed on the inner sidewall of the node reinforcing block 8. The threaded connecting sleeves 16 located at both ends of the outer wall of the reinforcing crossbar 12 are rotated, and the threaded connecting sleeves 16 will achieve threaded rotation on the external threads 14 opened at both ends of the outer wall of the reinforcing crossbar 12, and rotate and move outward in the threaded direction until the threaded connecting sleeves 16 and the threaded short rods 10 are threaded together and the threaded connecting sleeves 16 can no longer be rotated. Then the reinforcing crossbar 12 can be fixedly installed in the inner stiffening plates 5 in a transverse manner. The reinforcing crossbar 12 and the threaded short rods 10 are connected by thread. The node reinforcing blocks 8 are firmly connected together, realizing a reliable connection between the various components of the reinforcing mechanism 4. This allows the reinforcing connecting crossbar 12 to be stably and accurately installed between the symmetrical node reinforcing blocks 8, which not only improves the convenience and accuracy of installation but also enhances the connection strength between the reinforcing connecting crossbar 12 and the node reinforcing blocks 8. This ensures that the reinforcing connecting crossbar 12 and the node reinforcing blocks 8 can be tightly combined, enabling the entire reinforcing mechanism 4 to work together better and jointly withstand external forces. This enhances the structural stability and load-bearing capacity of the entire reinforcing mechanism 4, thereby improving the strength and stability of the hydraulic shear support body 2. It meets the structural strength requirements of the hydraulic shear during operation and effectively improves the overall structural strength and stability of the hydraulic shear support body 2.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
