Description

Technical Field

[0001] This utility model relates to the technical field of cooling modules for engineering machinery, and specifically to a cooling module for engineering machinery that is easy to assemble and maintain. Background Technology

[0002] In existing technologies, most construction machinery cooling modules use a fully enclosed sheet metal frame, with each cooling and heat dissipation module installed within the internal cavity of the frame. Because the fully enclosed sheet metal frame uses a large amount of raw materials and is quite heavy, the assembled construction machinery cooling module is also heavy, making transportation and installation inconvenient. When a cooling or heat dissipation module malfunctions, disassembly or installation from within the sheet metal frame is extremely difficult, resulting in long maintenance and repair cycles and severely impacting the normal operation of the construction machinery cooling module. Therefore, this utility model proposes a construction machinery cooling module with improved assembly and maintenance convenience to solve the aforementioned technical problems. Summary of the Invention

[0003] The purpose of this utility model is to overcome the defects in the existing technology and provide a construction machinery cooling module with convenient assembly and maintenance. By designing the frame as a semi-enclosed integrated sheet metal structure, the total amount of raw materials used in the frame and the cost are effectively reduced, without significantly increasing the total weight of the finished construction machinery cooling module. This ensures that the construction machinery cooling module of this utility model is easy to transport and install. The hydraulic oil cooler, water tank radiator, and intercooler are wall-mounted and fixed at the rear end of the frame, making installation and disassembly convenient. This helps to significantly reduce the maintenance and repair time of the construction machinery cooling module and effectively reduce the impact on the normal operation cycle of the construction machinery cooling module. The overall structural design is ingenious and reasonable, with high feasibility for manufacturing and implementation, and strong practicality.

[0004] To achieve the above objectives, the technical solution of this utility model is to design a cooling module for engineering machinery with convenient assembly and maintenance, including a frame, a hydraulic oil cooler, a water tank radiator, an intercooler, and a fan. The frame includes a vertical base plate, and a frame plate extending rearward is integrally bent at the outer periphery of the vertical base plate. The vertical base plate and the frame plate at its outer periphery form a cavity with an opening facing rearward. The hydraulic oil cooler, water tank radiator, and intercooler are wall-mounted and fixed at the rear end of the frame. The front end of the fan is embedded and fixed inside a fan mounting hole opened on the vertical base plate, and the rear end of the fan extends into the cavity, with the fan's air outlet facing forward.

[0005] This utility model provides a convenient assembly and maintenance cooling module for engineering machinery. By designing the frame as a semi-enclosed integrated sheet metal structure, the total amount of raw materials used in the frame and the cost are effectively reduced. This avoids significantly increasing the overall weight of the finished cooling module, ensuring convenient transport and installation. The hydraulic oil cooler, water tank radiator, and intercooler are wall-mounted at the rear end of the frame, facilitating easy installation and disassembly. This significantly reduces maintenance and repair time, effectively minimizing the impact on the normal operating cycle of the cooling module. The overall structural design is ingenious and reasonable, with high feasibility and practicality.

[0006] A preferred technical solution is that the rear edges of both the left and right side panels of the frame are provided with ear plates extending outwards from the cavity. The hydraulic oil cooler, water tank radiator, and intercooler are all laid horizontally on the rear port of the frame, and their left and right ends are fixedly connected together by tie rod bolt assemblies that pass through the end caps and the corresponding mounting holes on the ear plates. The intercooler is located on the upper side, the hydraulic oil cooler in the middle, and the water tank radiator on the lower side. The left and right ends of the hydraulic oil cooler, water tank radiator, and intercooler are fixedly connected to the frame by tie rod bolt assemblies, which is a simple and stable installation method.

[0007] A further preferred technical solution is that a right-angled groove is provided at the upper right corner of the frame, and a water supply tank is installed inside the right-angled groove. The intercooler has a short horizontal length, and the water supply tank and intercooler are located in the same horizontal direction, which is well consistent with the horizontal width of the frame. The overall installation position of the heat dissipation module and the cooling module on the frame is reasonable, and the overall compactness is good, which helps to broaden the applicable working environment of the engineering machinery cooling module of this utility model.

[0008] A further preferred technical solution is that a support beam extending horizontally to the rear is welded and fixed to the right end of the bottom frame plate of the right-angled groove, and a support plate extending horizontally to the left is welded and fixed to the rear end of the support beam.

[0009] The water supply tank has a "7"-shaped structure. Its horizontal section overlaps the upper side of the support beam, and its vertical section fits against the rear side of the support plate. The right side of the horizontal section has a downward-extending mounting foot, and the vertical section has a left-extending mounting foot. Mounting foot one and the support beam are fixedly connected by bolts passing through corresponding mounting holes. Mounting foot two and the support plate are also fixedly connected by bolts passing through corresponding mounting holes. A pressure relief valve cover is installed at the top of the horizontal section's inlet, and a connecting pipe head one is located at the front end of the lower side of the horizontal section. A connecting pipe head two is located at the lower end of the left side of the vertical section. The "7"-shaped design of the water supply tank ensures good compatibility with the support beam and support plate at the bottom of the right-angled groove, providing excellent operability and facilitating connection to external equipment.

[0010] A further preferred technical solution includes a bracket fixed parallel to the rear sides of the hydraulic oil cooler, water tank radiator, and intercooler. A condenser, parallel to the rear side of the hydraulic oil cooler, is horizontally fixed above the rear side of the bracket, and a fuel cooler, parallel to the rear side of the water tank radiator, is horizontally fixed below the rear side of the bracket. The hydraulic oil cooler and fuel cooler are laid on the rear side of the frame via the bracket, resulting in a reasonable and compact layout, which helps to further improve the heat dissipation and cooling efficiency of the engineering machinery cooling module of this utility model.

[0011] A further preferred technical solution is that the bracket has ear plates with mounting holes at both ends, and the ear plates are fixed to the rear end of the corresponding tie rod bolt assembly through the mounting holes.

[0012] The condenser and fuel cooler each have ear plates with mounting holes at both ends. The two ends are fixedly connected by bolt assemblies that pass through the ear plates and the corresponding mounting holes on the bracket. The bracket is fixed to the frame at both ends by ear plates and tie rod bolt assemblies for fixing the ends of the heat dissipation module. The condenser and fuel cooler are also fixed to the bracket at both ends by bolt assemblies. This installation method is simple and easy to operate.

[0013] A further preferred technical solution includes several intersecting ribs perpendicular to the vertical base plate welded and fixed within the cavity of the frame. These ribs divide the cavity into several cavity units. The vertical base plate has several fan mounting holes, each housing a fan, with each cavity unit corresponding to a fan mounting hole. The ribs improve the structural strength and rigidity of the frame, effectively preventing deformation due to excessive load after assembly into a cooling module for engineering machinery. The multiple fans provide independent airflow and heat dissipation, ensuring that even if one fan malfunctions, it will not instantly affect the normal operation of the engineering machinery cooling module.

[0014] A further preferred technical solution includes welding and fixing triangular reinforcing plates to the corner positions of the rear end edges of the upper frame panels, and welding and fixing stiffeners to the ear plates and their corresponding frame panels. The triangular reinforcing plates help improve the structural strength at the weak corner positions of the frame, while the stiffeners improve the connection strength between the ear plates and their corresponding frame panels, thus enhancing the secure installation of the heat dissipation and cooling modules on the frame.

[0015] A further preferred technical solution is that the fan is an electronic fan. Electronic fans facilitate independent control of each fan through a control system, allowing for flexible selection of the fan to operate based on actual operating conditions.

[0016] A further preferred technical solution is that a plurality of mounting seats are fixedly provided on the lower side of the bottom frame plate of the frame. When the engineering machinery cooling module of this utility model is installed and used, the bottom mounting seats can be fixedly connected to the engineering equipment, offering convenient installation and disassembly, and high stability.

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

[0018] 1. This utility model provides a convenient assembly and maintenance cooling module for engineering machinery.

The hydraulic oil cooler, water tank radiator, and intercooler are wall-mounted and fixed at the rear end of the frame, making installation and disassembly convenient. This helps to significantly reduce the maintenance and repair time of the engineering machinery cooling module and effectively reduce the impact on the normal operation cycle of the engineering machinery cooling module. The overall structural design is ingenious and reasonable, with high feasibility for preparation and implementation and strong practicality.

[0019] 2. The hydraulic oil cooler, water tank radiator, and intercooler are fixedly connected to the frame at both ends by tie rod bolt assemblies. The fixed installation method is simple and has good stability and firmness.

[0024] 7.
