[0023] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.
[0024] See also Figure 1-3 As shown, according to an embodiment of the present application, an integrated hydraulic puller hook is provided, comprising: a hydraulic cylinder 1, a pressure rod 2, a push rod 3, a sleeve 4, an annular hook seat 5, a first fixed arm 6, a second fixed arm 7, a first connecting member 8, a hook assembly 9 and a second connecting member 10;
[0025] A pressure rod 2 is provided on the top of the hydraulic cylinder 1, a first end of the push rod 3 is connected to the output end of the hydraulic cylinder 1, the sleeve 4 is connected to the hydraulic cylinder 1 and sleeved on the outside of the push rod 3, the annular hook seat 5 is provided on the sleeve 4, a first fixed arm 6 is provided on the annular hook seat 5, a first end of the second fixed arm 7 is connected to the first fixed arm 6 through a first connecting member 8, and the hook assembly 9 is connected to the second end of the second fixed arm 7 through a second connecting member 10;
[0026] The hook assembly 9 includes a fixing sleeve 11 and a disassembly rod 12, the disassembly rod 12 is connected to the fixing sleeve 11, the fixing sleeve 11 is connected to the second end of the second fixing arm 7 through the second connecting member 10, and the outer circumference of the disassembly rod 12 away from the fixing sleeve 11 is at least partially provided with an external thread.
[0027] Specifically, the existing integrated hydraulic puller hook has an arc-shaped rod and a hook at the bottom of the arc-shaped rod. When the disc, flange and bearing are disassembled, the bottom hook can fix the disc, flange and the bottom of the bearing, and then by pressing the pressure rod 2, the output end of the hydraulic cylinder 1 can drive the push rod 3 in the middle to extend out of the sleeve 4 and contact the shaft of the disc, flange and bearing. In the process of continuous extension of the push rod 3, the disc, flange and bearing can be disassembled; when the fan blade needs to be disassembled, the fan blade is originally provided with a screw hole, and a hook suitable for it is selected according to the size of the screw hole of the fan blade. Component 9, first thread the disassembly rod 12 and the fan blade screw hole, and then disassemble the hook claw component through the second connecting piece 10. After disassembly, connect the fixing sleeve 11 on the hook claw component 9 with the second fixing arm 7, and then continuously press the pressure rod 2, and the push rod 3 continuously extends to push the fan blade shaft to realize the disassembly of the fan blade. The disassembly process does not require replacing the entire puller hook claw. You only need to use the original hook claw component and replace the original hook claw component with the hook claw component 9 to complete the disassembly of each component in the motor. It is easy to operate and saves maintenance time. In addition, there is no need to carry two puller hook claws during maintenance, which is convenient for maintenance.
[0028] Among them, the first end of the second fixed arm 7 is connected to the first fixed arm 6 through the first connecting member 8, and the hook claw assembly 9 is connected to the second fixed arm 7 through the second connecting member 10. Therefore, the second fixed arm 7 can rotate relative to the first fixed arm 6, and the hook claw assembly 9 can rotate relative to the second fixed arm 7, realizing movement with multiple degrees of freedom, and being able to disassemble fan blades of different sizes, thereby increasing the scope of use.
[0029] The hook assembly 9 is connected to the second fixed arm 7 via a second connecting member 10, so that hook assemblies 9 of different sizes can be selected according to the fan blades of different sizes, thereby improving the disassembly efficiency.
[0030] The hook assembly 9 can be welded with discarded nuts and screw rods, saving raw materials and costs.
[0031] The second fixing arm 7 includes a first fixing plate 13 and a second fixing plate 14, wherein the first ends of the first fixing plate 13 and the second fixing plate 14 are respectively arranged on both sides of the first fixing arm 6 and connected by the first connecting member 8, and the second ends of the first fixing plate 13 and the second fixing plate 14 are respectively arranged on both sides of the fixing sleeve 11 and connected by the second connecting member 10.
[0032] Specifically, the second fixed arm 7 includes a first fixed plate 13 and a second fixed plate 14, which are respectively installed on both sides of the first fixed arm 6 and the fixed sleeve 11 through a first connecting member 8 and a second connecting member 10, so as to improve the fixing performance of the fixed sleeve 11 after installation.
[0033] The first connecting member 8 and the second connecting member 10 are both screw rods and nuts.
[0034] The outer circumference of the sleeve 4 is provided with external threads, and the annular hook seat 5 is threadedly connected to the sleeve 4 .
[0035] Specifically, the annular hook claw seat 5 is threadedly connected to the sleeve 4, so that the position of the annular hook claw seat 5 on the sleeve 4 can be adjusted according to usage requirements, thereby adjusting the distance between the sleeve 4 and the push rod 3 and the axis of the object to be disassembled, reducing the distance between the sleeve 4 and the axis of the object to be disassembled, and improving subsequent disassembly efficiency.
[0036] The second end of the push rod 3 is detachably provided with a top sleeve 15 .
[0037] The top sleeve 15 is threadedly connected to the second end of the push rod 3 .
[0038] Specifically, the top sleeve 15 is installed on the second end of the push rod 3 through a thread. It does not need to be installed when not in use. It is installed before use. In this way, when disassembling, the top sleeve 15 is in direct contact with the shaft of the object to be disassembled, which reduces the probability of damage to the push rod 3 and increases its service life.
[0039] Wherein, the top sleeve 15 is made of hard metal.
[0040] The hydraulic cylinder 1 is provided with a pressure relief switch 16 .
[0041] Specifically, after or before use, the pressure relief switch 16 is opened to release pressure, so that the push rod 3 is completely retracted into the sleeve 4, and then the pressure relief switch 16 is closed.
[0042] The above are only preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application shall be included in the protection scope of the present application. The above are only preferred implementations of the present application.
