Description

Technical Field

[0001] This utility model relates to the field of radiator technology, specifically to a shock-absorbing structure for radiators with good maintenance convenience. Background Technology

[0002] The market demand for construction machinery is increasing, leading to larger radiators to meet their cooling requirements. Construction machinery operates in harsh environments, resulting in a high failure rate for its components, particularly the radiator, which provides cooling for the engine. Since the radiator is directly mounted on the chassis, significant chassis vibration during vehicle operation causes the radiator to vibrate. Excessive chassis vibration can exceed the radiator's tolerance, leading to damage. Therefore, appropriate vibration damping structures are necessary to protect the radiator.

[0003] Due to the high vibration levels in the working environment of construction machinery, the vibration damping structure on the radiator is prone to damage and failure, requiring regular inspection or replacement. However, most existing vibration damping structures on radiators are directly fixed to the outer frame, making installation and disassembly inconvenient. This results in difficult replacement of the vibration damping structure and prolonged maintenance time, severely impacting the operating efficiency of construction machinery. Therefore, this invention proposes a vibration damping structure for radiators with improved maintenance convenience to solve the aforementioned technical problems. Summary of the Invention

[0004] The purpose of this utility model is to overcome the defects existing in the prior art and provide a shock-absorbing structure for radiators with good maintenance convenience. The rectangular frame structure consists of four side frames (top, bottom, left, and right) that are detachably fixed together by bolt assemblies at the ends. The upper end cap of the radiator body is installed inside the cavity of the upper side frame through several shock-absorbing units. The lower end cap of the radiator body is inserted into and abuts against a shock-absorbing unit fixed at the bottom of the cavity of the lower side frame. The shock-absorbing unit provides front-to-back abutment and shock absorption for the upper end of the radiator body. The vibration damping unit 1, together with the vibration damping unit 2, provides longitudinal contact and damping for the radiator body, thereby effectively reducing the vibration amplitude and swaying displacement of the radiator body within the rectangular frame. This ensures that the radiator has excellent vibration damping performance and stability when installed on engineering machinery. During maintenance, the upper side frame, left side frame, right side frame, and vibration damping unit 2 can be disassembled to hoist the radiator body down, ensuring convenient and efficient maintenance and replacement of vibration damping units 1 and 2. The overall structural design is ingenious and reasonable, with high feasibility for manufacturing and implementation, and strong practicality.

[0005] To achieve the above objectives, the technical solution of this utility model is to design a shock-absorbing structure for radiators with good maintenance convenience, including a radiator body. The radiator body is embedded in a rectangular frame structure formed by four parts: a left side frame, an upper side frame, a right side frame, and a lower side frame, which are joined end to end. The ends of two adjacent side frames are fixedly connected together by bolt assemblies that pass through the front and rear side walls of the two parts. The upper end of the radiator body has an upper end cap inserted into the cavity of the upper side frame, and the lower end has a lower end cap inserted into the cavity of the lower side frame. Several shock-absorbing units are fixedly fixed along the length direction on the upper side of the bottom of the lower side frame cavity to abut and support the lower end cap. The upper end cap and the front and rear side walls of the upper side frame are connected together by several shock-absorbing units that are vertically inserted into the three parts.

[0006] This utility model discloses a vibration damping structure for radiators with convenient maintenance. The rectangular frame structure consists of four side frames (top, bottom, left, and right) that are detachably fixed together by bolt assemblies at the ends. The upper end cap of the radiator body is installed inside the cavity of the upper side frame via several vibration damping units (II). The lower end cap of the radiator body is inserted into and abuts against a vibration damping unit (I) fixed at the bottom of the lower side frame cavity. The vibration damping units (II) provide front-to-back abutment and vibration damping for the upper end of the radiator body, while the vibration damping units (I, II) work together to provide longitudinal abutment and vibration damping for the radiator body. This effectively reduces the vibration amplitude and swaying displacement of the radiator body within the rectangular frame, ensuring excellent vibration damping performance and stability when the radiator is installed on engineering machinery. During maintenance, the upper, left, and right side frames and the vibration damping units (II) can be disassembled, allowing the radiator body to be hoisted down, ensuring convenient and efficient maintenance and replacement of the vibration damping units (I, II). The overall structural design is ingenious and reasonable, with high feasibility for implementation and strong practicality.

[0007] The preferred technical solution is that the first damping unit includes a base plate, a damping block, and a top plate. The top plate is laid flat and fixed on the top of the damping block, and the base plate is laid flat and fixed on the bottom of the damping block. The base plate and the top plate are made of carbon steel. The portions of the base plate extending to the outside of the left and right ends of the damping block are provided with through holes penetrating the plate. The first damping unit is fixedly installed at the bottom of the cavity of the lower frame by bolt assemblies that pass through the through holes at the left and right ends of the base plate. The lower end cap is placed on the top plate.

[0008] The second shock-absorbing unit includes a connecting rod, with a bushing assembly symmetrically sleeved at both ends of the connecting rod. One end of the bushing assembly facing the corresponding end of the connecting rod has an abutment extending outward. One end of the connecting rod has an end cap, and a nut is screwed onto the threaded section of the other end. The connecting rod passes through the front and rear side walls of the upper end cap and the upper side frame. The connecting rod pulls and locks the front and rear side walls of the upper end cap and the upper side frame together through the end cap and the nut. The abutment on one bushing assembly abuts against the inner wall surface of the front side wall of the upper side frame, and the abutment on the other bushing assembly abuts against the inner wall surface of the rear side wall of the upper side frame. The first damping unit has a clever and reasonable structural design. Both the bottom plate and the top plate are made of carbon steel, which ensures that the first damping unit has good overall wear resistance. It also allows the weight of the radiator body to be evenly distributed across the entire damping block through the top plate, which helps to improve the longitudinal damping performance of the first damping unit on the radiator body. The second damping unit has a clever and reasonable structural design. During use, two sets of bushing components are inserted into the inside of the upper end cap from the front and rear sides. The installation and disassembly are simple. The ends of the bushing components abut against the corresponding front or rear side wall of the upper side frame through the abutment edge, so that the front and rear sides of the upper end cap and the front and rear side walls of the upper side frame form a flexible contact, avoiding vibration and abnormal noise, and providing good vibration buffering performance.

[0009] A further preferred technical solution is that a number of pins are vertically fixed to the top of the base plate, the shock absorber is made of rubber, the base plate and the top plate are integrally vulcanized and fixed on the shock absorber, and the upper end of the pins passes through the shock absorber and the top plate and is inserted into the corresponding insertion hole at the bottom of the lower end cap.

[0010] Each bushing assembly includes a bushing one and a bushing two. Bushing one is made of rubber, and bushing two is made of stainless steel. Bushing one is vulcanized and molded inside bushing two. One end of bushing two has an eave body two extending outward and a countersunk groove located on the inner side. One end of bushing one has an eave body one extending outward and embedded in the countersunk groove on the corresponding bushing two. Eave body one and eave body two constitute the abutment eave. The base plate and top plate are integrally vulcanized and fixed to the damping block, ensuring good overall consistency of the damping unit. The upper end of the pin is inserted into the corresponding insertion hole at the bottom of the lower end cap, so that the damping unit provides front-to-back limiting for the lower end of the radiator body, further ensuring the installation stability of the radiator body within the rectangular frame. The bushing assembly has a clever and reasonable structural design. The first bushing is made of rubber to ensure that the second damping unit has a good damping effect in the axial direction, while the second bushing is made of stainless steel to ensure that the second damping unit provides good rigid support to the upper end cap, effectively preventing excessive longitudinal vibration displacement of the radiator body due to severe longitudinal deformation of the second damping unit.

[0011] A further preferred technical solution is that the width of the inner cavity of the upper frame along the front-to-back direction is set as d1, the axial length of the first bushing is set as d2, and the axial length of the second bushing is set as d3. Then, 1 / 3d1 < d2 < 1 / 2d2, and d3 ≤ 1 / 2d2. The axial lengths of the first and second bushings are reasonably designed to ensure the smooth fabrication and implementation of the second vibration unit.

[0012] A further preferred technical solution includes that the connecting rod is fitted with washers located between the end cap and the front or rear side wall of the upper side frame, and between the nut and the front or rear side wall of the upper side frame. The washers further improve the tightness of the connection between the vibration unit two and the upper end cap and the front and rear side walls of the upper side frame, while also providing an anti-loosening effect, helping to ensure the long-lasting good axial damping performance of the vibration damping unit two.

[0013] A further preferred technical solution is that the upper outer side of the bushing two has a protruding ridge one extending along its axial length direction, and the lower outer side of the bushing two has two protruding ridges two extending along its axial length direction. The protruding ridge one and the two protruding ridges two are distributed on the same cross-section of the bushing two at the three vertices of the same triangle. The lower outer side of the bushing two also has a bottom plane extending along its axial length direction and located between the two protruding ridges two.

[0014] The upper end cap is fitted with several sleeves that pass through its front and rear ends at intervals along its left and right length. The upper surface of the inner wall of each sleeve has a groove along its axial length. The second damping unit passes through the inside of each sleeve, and the first protrusion on the second bushing passes through the groove inside the sleeve. The two second protrusions on the lower side of the second bushing abut against the lower side of the inner wall of the sleeve. The bottom plane of the second bushing and the portion of the inner cavity of the sleeve located below the second bushing form a buffer cavity. The first protrusion on the second bushing, passing through the groove inside the sleeve on the upper end cap, provides positioning and prevents rotation of the second bushing. The two second protrusions on the lower side of the second bushing abut against the lower side of the inner wall of the sleeve on the upper end cap further improve the installation stability of the second bushing inside the sleeve. When the radiator body expands due to heat, the buffer cavity provides a certain buffering effect on its longitudinal height change, effectively preventing irreversible deformation of the radiator body due to thermal expansion.

[0015] A further preferred technical solution includes that the top left and right ends of the upper end cap each have upwardly extending positioning pins, and the top left and right ends of the upper side frame each have positioning holes corresponding to the positioning pins. The positioning pins are inserted into the corresponding positioning holes. The insertion of the positioning pins at the top of the upper end cap into the corresponding positioning holes at the top of the upper side frame ensures convenient insertion and positioning during assembly of the upper side frame and the upper end cap. Furthermore, it provides front-to-back positioning for both the upper side frame and the upper end cap, helping to improve the stability of the radiator body within the rectangular frame.

[0016] A further preferred technical solution is that the left side frame is fixedly connected to the radiator body via screw assemblies passing through its vertical bottom wall and corresponding mounting holes on the left side surface of the radiator body, and the right side frame is fixedly connected to the radiator body via screw assemblies passing through its vertical bottom wall and corresponding mounting holes on the right side surface of the radiator body. During maintenance, the upper side frame and vibration damping unit two can be disassembled, and the bolt assemblies connecting the lower ends of the left and right side frames to the lower side frame can be removed, allowing the radiator body to be hoisted down. This further improves the convenience and efficiency of maintenance and replacement of vibration damping unit one and vibration damping unit two.

[0017] The advantages and beneficial effects of this utility model are as follows:

[0018] 1. This utility model discloses a shock-absorbing structure for a radiator with good maintenance convenience. The rectangular frame structure consists of four side frames (upper, lower, left, and right) that are detachably fixed together by bolt assemblies at the ends. The upper end cap of the radiator body is installed inside the cavity of the upper side frame through several shock-absorbing units (II). The lower end cap of the radiator body is inserted into and abuts against a shock-absorbing unit (I) fixed at the bottom of the cavity of the lower side frame. The shock-absorbing units (II) provide front-to-back abutment and shock absorption for the upper end of the radiator body, while the shock-absorbing units (I) work together to reduce vibration. Vibration unit two acts as a longitudinal contact limiter and shock absorber for the radiator body, thereby effectively reducing the vibration amplitude and swaying displacement of the radiator body inside the rectangular frame, ensuring excellent shock absorption performance and stability when the radiator is installed on engineering machinery; during maintenance, the upper side frame, left side frame, right side frame and vibration unit two can be disassembled to hoist the radiator body down, ensuring convenient and efficient maintenance and replacement of vibration unit one and vibration unit two; the overall structural design is ingenious and reasonable, with high feasibility for manufacturing and implementation, and strong practicality.

[0019] 2. The first damping unit has a clever and reasonable structural design. Both the bottom plate and the top plate are made of carbon steel, which ensures that the first damping unit has good overall wear resistance. It also makes the weight of the radiator body evenly distributed on the entire damping block through the top plate, which helps to improve the longitudinal damping performance of the first damping unit for the radiator body. The second damping unit has a clever and reasonable structural design. When in use, two sets of bushing components are inserted into the inside of the upper end cap from the front and rear sides. The installation and disassembly are simple. The ends of the bushing components abut against the corresponding front or rear side wall of the upper side frame through the abutment edge, so that the front and rear sides of the upper end cap and the front and rear side walls of the upper side frame form a flexible contact, avoiding vibration and abnormal noise, and providing good vibration buffering performance.

[0020] 3. The bottom plate and top plate are integrally vulcanized and fixed on the damping block, ensuring good overall consistency of the damping unit. The upper end of the pin is inserted into the corresponding insertion hole at the bottom of the lower end cap, so that the damping unit provides front-to-back limiting for the lower end of the radiator body, further ensuring the installation stability of the radiator body within the rectangular frame. The bushing assembly has a clever and reasonable structural design. The first bushing is made of rubber to ensure that the second damping unit has a good damping effect in the axial direction, while the second bushing is made of stainless steel to ensure that the second damping unit provides good rigid support for the upper end cap, effectively preventing excessive longitudinal vibration displacement of the radiator body due to severe longitudinal deformation of the second damping unit.

[0021] 4. The first protrusion on the bushing 2 passes through the groove inside the sleeve on the upper end cap, which plays a role in positioning and preventing rotation of the bushing 2; the two protrusions on the lower side of the bushing 2 abut against the lower side of the inner wall of the sleeve on the upper end cap, which further improves the installation stability of the bushing 2 inside the sleeve; when the radiator body expands due to heat, the buffer cavity has a certain buffering effect on its longitudinal height change, which effectively prevents the radiator body from undergoing irreversible deformation due to thermal expansion.

[0022] 5. The positioning pin at the top of the upper end cap is inserted into the corresponding positioning hole at the top of the upper side frame. This ensures convenient insertion and positioning when assembling the upper side frame and the upper end cap, and also limits the front and rear directions of the upper side frame and the upper end cap, which helps to improve the installation stability of the radiator body inside the rectangular frame.

[0023] 6. The left side frame is fixedly connected to the radiator body via screw assemblies that pass through its vertical bottom wall and into corresponding mounting holes on the left side surface of the radiator body. The right side frame is also fixedly connected to the radiator body via screw assemblies that pass through its vertical bottom wall and into corresponding mounting holes on the right side surface of the radiator body. During maintenance, the upper side frame and vibration damping unit two can be disassembled, and the bolt assemblies connecting the lower ends of the left and right side frames to the lower side frame can be removed, allowing the radiator body to be hoisted down. This further improves the convenience and efficiency of maintenance and replacement of vibration damping unit one and vibration damping unit two. Attached Figure Description
