Description

Technical Field

[0001] This utility model belongs to the field of head installation technology, and in particular relates to a hoisting tool for installing EGR cooler heads. Background Technology

[0002] The EGR cooler (exhaust gas recirculation cooler) is a core component of the exhaust gas recirculation (EGR) system in automotive engines. It is mainly used to reduce the temperature and pressure of the combustion chamber by cooling the recirculated exhaust gas, thereby reducing the emission of nitrogen oxides (NOx) in the exhaust gas.

[0003] In practical use, the EGR cooler heads require regular maintenance and replacement to prevent carbon buildup and blockage, and to maintain cooling efficiency. Severe carbon buildup in the heads can lead to excessively high exhaust temperatures, affecting the EGR system's nitrogen oxide emission reduction effect, and may also cause problems such as decreased engine combustion efficiency and increased fuel consumption.

[0004] Currently, during the regular maintenance of EGR cooler heads, it is unavoidable to disassemble them and then reinstall them after maintenance. This process is mostly carried out manually. On the one hand, for workpieces of different specifications and sizes, the labor cost needs to be adjusted according to the actual processing conditions. For example, if two or more people are required to lift and place them, the production cost will be high, and improper coordination among multiple workers may pose certain dangers. On the other hand, the installation process also requires consideration of various factors, such as adjusting the height of one side to ensure successful installation. This process increases the labor intensity of workers, affects the work progress, and fails to meet the usage requirements. Utility Model Content

[0021] Examples, such as Figures 1-4As shown, a hoisting tool for installing an EGR cooler head includes a movable frame 1. A support platform 1a is provided on the upper rear side of the movable frame 1. One side of the upper end of the support platform 1a is inclined to provide effective support for a rotating frame 2. A rotating frame 2 with an obtuse angle is provided above the movable frame 1. One end of the rotating frame 2 is rotatably positioned relative to the movable frame 1, allowing for easy adjustment of its position according to different usage needs and providing a prerequisite for loading workpieces. A trapezoidal support frame 3 is inclined above the rotating frame 2. An extension frame 4 arranged in a triangular pattern is provided on one side of the support frame 3. The support frame 3 is fixedly connected to the rotating frame 2, and the extension frame 4 is fixedly connected to the support frame 3 to ensure the stability of the device. A first winch 5 is arranged in parallel on the rear side of the movable frame 1. The first hoisting assembly 7 is installed on the support frame 3 and the second hoisting assembly 8 is installed on the extension frame 4. By utilizing the first hoisting assembly 7 and the second hoisting assembly 8, the two hoisting assemblies can be operated synchronously to realize the vertical lifting and lowering adjustment of the workpiece in a horizontal state, thus achieving convenient conditions for the height position. In addition, according to different installation and use requirements, one of the hoisting assemblies can be controlled to operate independently to adjust the hoisting position of the workpiece to meet the installation requirements. This setup can effectively replace manual labor, reduce labor intensity, and improve the functionality of the equipment. An adjustable hanger 9 is installed below the first hoisting assembly 7 and the second hoisting assembly 8, which can be adapted to workpieces of different specifications and sizes to achieve stable hoisting, providing the prerequisites for the installation work and meeting the use requirements.

[0022] In the above process: using the established first lifting component 7 and second lifting component 8, the two lifting components can be operated synchronously to achieve vertical lifting and lowering adjustment of the workpiece in a horizontal state, thus facilitating the achievement of height position. In addition, according to different installation and usage requirements, one of the lifting components can be controlled independently to adjust the lifting position of the workpiece to meet the installation requirements. This system can effectively replace manual labor, reduce labor intensity, and improve the functionality of the equipment. Utilizing the established adjustable hanger 9, it can be adapted to workpieces of different specifications and sizes to achieve stable lifting, providing the prerequisites for the installation work and meeting usage requirements. This device is reasonably designed, has a simple structure, is easy to process, and can achieve convenient lifting and placing of workpieces. On the one hand, it can adapt to workpieces of different specifications and sizes, improving the practicality of the equipment. On the other hand, it can freely adjust the position of the workpiece according to different processing and usage requirements, ensuring the smooth progress of the installation work, reducing labor intensity, and guaranteeing the work progress.

[0023] To meet different hoisting needs, and especially to improve the functionality of the equipment, a crossbar 31 is provided on the inner side of the support frame 3. The first hoisting assembly 7 includes a first fixed pulley 71 on the crossbar 31, a second fixed pulley 72 on the front side of the support frame 3, a first winch rope 73 on the first winch 5 wound around the first fixed pulley 71 and exiting through the second fixed pulley 72, and a first hook 74 is provided at the end of the first winch rope 73. For the established first hoisting assembly 7, controlling the operation of the first winch 5 drives the... The first hoisting rope 73 runs through the first fixed pulley 71 and the second fixed pulley 72, thereby acting on the first hook 74 and driving the adjustable hoist 9 to rise and fall vertically. The second hoisting assembly 8 includes a third fixed pulley 81 mounted on the crossbar 31, a fourth fixed pulley 82 mounted parallel to the extension frame 4 on the front side of the support frame 3, and a rotatable and adjustable fifth fixed pulley 83 at the end of the extension frame 4. The second hoisting rope 84 on the second winch 6 is wound around the third fixed pulley 81 and the fourth fixed pulley 82, and then passes through the fifth fixed pulley. The second winch rope 84 is equipped with a second hook 85 at its end. Furthermore, the rotation direction of the fourth fixed pulley 82 is parallel to that of the extension frame 4, ensuring the smooth operation of the second winch rope 84. Simultaneously, a limit rod is provided on the outer side of the fourth fixed pulley 82 to prevent it from detaching. The mounting end of the fifth fixed pulley 83 can rotate relative to the extension frame 4 to accommodate the operation of the second winch rope 84. During use, the second winch 6 is controlled to drive the second winch rope 84 through the third fixed pulley 81... The fourth fixed pulley 82 and the fifth fixed pulley 83 operate and act on the second hook 85, causing one end of the adjustable hanger 9 to be raised and lowered vertically. During use, to meet different usage needs, the two winches can operate together, so that the adjustable hanger 9 can be lifted or lowered horizontally in the vertical direction. According to other usage needs, such as when one end of the adjustable bracket is high and the other end is low, one winch can be controlled to operate independently to meet the corresponding usage needs and provide convenient conditions for the installation of the workpiece.

[0024] To accommodate workpieces of different sizes and specifications for flexible lifting operations, the adjustable lifting frame 9 includes a frame 91. Lifting rings 911 are located on both sides of the upper part of the frame 91. These lifting rings 911 can rotate circumferentially to adapt to the needs of workpiece lifting. Multiple limiting blocks 92 are equidistantly arranged on the frame 91 on one side of the lifting rings 911. A movable and adjustable lifting assembly 10 is located between adjacent limiting blocks 92. The lifting assembly 10 includes a concave-shaped connecting frame 101. A rotating plate 102 is located below the connecting frame 101. The rotating plate 102 can rotate relative to the connecting frame 101. When the adjustable lifting frame 9 is adjusted to be higher or lower at one end according to different usage needs, the rotating plate 102 can handle these situations, especially providing a prerequisite for the stable positioning of the workpiece, improving the practicality of the equipment. The frame is equipped with a third hook 103. A mounting sleeve 104 with a U-shape is located above the connecting frame 101. A connecting screw 105 is located on the outer side of the mounting sleeve 104 and is connected to a limiting block 92. Specifically, the limiting block 92 is integrally formed with the frame 91 and has a screw hole, facilitating the connection of the connecting screw 105 to the connecting sleeve and the frame 91. Furthermore, the upper part of the connecting frame 101 is fitted with the gap between two adjacent limiting blocks 92. First, the position of the connecting frame 101 is adjusted according to the workpiece's dimensions. Then, the mounting sleeve 104 is fastened onto the connecting frame 101, and the connecting screw 105 is used to connect the mounting sleeve 104 to the limiting block 92 to ensure its stability. Then, the third hook 103 is used to lift the rope tied to the workpiece, thus completing the convenient lifting of the workpiece and providing convenient conditions for the smooth progress of subsequent installation work.

[0025] To facilitate the adjustment of the adjustable hanger 9, a vertical slide bar 106 is provided on the inner side of the connecting frame 101, and a vertical slider 107 is provided on the vertical slide bar 106. A horizontal plate 108 is provided on the front side of the frame 91 corresponding to the limit block 92, and a horizontal slide bar 109 is provided on the horizontal plate 108. A horizontal slider 1010 is provided on the horizontal slide bar 109 and is connected to the vertical slider 107. Specifically, the vertical slider 107 and the horizontal slider 1010 are connected together. When it is necessary to adjust the position of the hanger assembly 10, first loosen the connecting screw 105, and then lift the connecting frame 101 upwards to make the connection... The connecting frame 101 rises vertically relative to the vertical slider 107, thereby disengaging it from between the two limiting blocks 92. Then, according to the specifications and dimensions of the workpiece to be lifted, the position of the connecting frame 101 is adjusted horizontally, that is, the horizontal slider 1010 is adjusted horizontally relative to the horizontal slide bar 109 until the top of the connecting frame 101 is engaged between the two adjacent limiting blocks 92. Then, the connecting screw 105 passes through the mounting sleeve 104 and is threadedly connected to the limiting block 92. This design makes the lifting assembly 10 more convenient to move and adjust, greatly improves the functionality of the device, and is simple, convenient, and practical.

[0026] To improve the functionality of the device, a support rod 21 is installed inside the rotating frame 2. A drive cylinder 11 is installed on one side of the support rod 21, and its output end is hinged to the upper front side of the moving frame 1. During use, the drive cylinder 11 is controlled to operate according to the requirements of the workpiece hoisting position. When it retracts, the rotating frame 2 can rotate away from the winch, so that the hoisted workpiece is closer to the installation position, which facilitates the workpiece loading. Of course, when one end of the rotating frame 2 is in contact with the support platform 1a and is placed vertically and stably, the workpiece can also be loaded. However, maintaining this mode of use is inconvenient. The rotation adjustment of the rotating frame 2 can improve the functionality of the device to a certain extent and meet different usage requirements.
