[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0027] This utility model provides a boom disassembly tool, the structure of which is as follows: Figure 1 - Figure 5 As shown, it includes a support mechanism 1, a drive mechanism 3, and a fixing mechanism 4.

[0028] The support mechanism 1 includes a fixed bracket 11 and a movable bracket 12. The fixed bracket 11 is used to support the front section 21 of the boom 2, and the movable bracket 12 is used to support the rear section 22 of the boom 2.

[0029] The fixed end of the drive mechanism 3 is used to be installed on one side of the front section 21 of the boom 2, and the movable end of the drive mechanism 3 is used to be installed on one side of the rear section 22 of the boom 2, so as to drive the rear section 22 of the boom 2 to move.

[0030] The fixing mechanism 4 is connected to the driving mechanism 3 and is used to fix the fixed end of the driving mechanism 3 to the front section 21 of the boom 2. The fixing mechanism 4 is used to fix the movable end of the driving mechanism 3 to the rear section 22 of the boom 2.

[0031] In use, the fixed bracket 11 is installed and supported on the front boom 21, and the movable bracket 12 is installed and supported on the rear boom 22. The fixed bracket 11 provides a relatively stable support base for the entire fixture, while the movable bracket 12 provides auxiliary support as the rear boom 22 moves, ensuring reliable support for both the front and rear booms 22 during disassembly and preventing them from swaying or tipping over. The fixed end of the drive mechanism 3 is securely fixed to one side of the front boom 21 using the fixing mechanism 4, while the movable end of the drive mechanism 3 is fixed to one side of the rear boom 22. The function of the fixing mechanism 4 is to ensure a reliable connection between the drive mechanism 3 and the front and rear booms 22, so that the force generated by the drive mechanism 3 can be effectively transmitted to the front and rear booms 22. This allows the front and rear booms 22 to gradually separate, thus achieving the disassembly of the boom 2.

[0032] In this invention, the cooperation between the support mechanism 1 and the fixing mechanism 4 ensures that the force of the drive mechanism 3 can be accurately applied to the arm section, avoiding disassembly difficulties caused by force dispersion or inaccurate transmission. The drive mechanism 3 provides a stable and controllable driving force, which can quickly separate the front and rear arm sections 22, thus improving work efficiency.

[0033] To accommodate booms of different heights, please refer to [reference 2]. Figure 3In a preferred embodiment, the movable support 12 includes a sliding seat, a lifting frame 123, and a lifting assembly 124. The sliding seat includes a base 121 and a roller 122. The roller 122 is connected to the bottom of the base 121. The lifting frame 123 is slidably connected to the base 121 along the height direction of the boom 2. The lifting frame 123 is used to support the bottom of the rear section 22 of the boom 2. The fixed end of the lifting assembly 124 is connected to the base 121, and the movable end of the lifting assembly 124 is connected to the lifting frame 123.

[0034] In use, the lifting frame 123 can move vertically up and down on the base 121, thereby changing its height relative to the ground to adapt to the support requirements of the rear boom 22 at different heights. The fixed end of the lifting assembly 124 is connected to the base 121, and the movable end is connected to the lifting frame 123. When the lifting assembly 124 is activated, the movable end will shift relative to the fixed end. The rollers 122 are connected to the bottom of the base 121, which allows the entire mobile support 12 to move flexibly on the ground.

[0035] To achieve the raising and lowering of the lifting frame 123, please refer to... Figure 2 In a preferred embodiment, the lifting assembly 124 includes a worm gear 1241, a worm wheel 1242, and a lead screw 1243. The worm gear 1241 is rotatably connected to the base 121 and extends along the width direction of the boom 2. The lead screw 1243 is rotatably connected to the base 121 and extends along the height direction of the boom 2. The worm wheel 1242 is connected to the lead screw 1243 and meshes with the worm gear 1241. The lead screw 1243 passes through the lifting frame 123 and is threadedly connected to the lifting frame 123.

[0036] In use, when the height of the lifting frame 123 needs to be adjusted, the worm gear 1241 is driven to rotate, causing it to rotate around its own axis. The worm gear 1241 meshes with the worm wheel 1242. When the worm gear 1241 rotates, its circular motion drives the worm wheel 1242 to rotate. The worm wheel 1242 is connected to the lead screw 1243, so its rotation drives the lead screw 1243 to rotate synchronously. The lead screw 1243 is rotatably connected to the base 121 and extends along the height direction of the boom 2. Simultaneously, the lead screw 1243 passes through the lifting frame 123 and is threadedly connected to it. The rotation of the lead screw 1243 causes the threaded lifting frame 123 to produce linear motion. Depending on the direction of rotation of the lead screw 1243, the lifting frame 123 will move upward or downward along the lead screw 1243.

[0037] To protect boom 2, please refer to... Figure 2In a preferred embodiment, the movable support 12 further includes an elastic layer 125, which is connected to the side of the lifting frame 123 near the rear arm 22 of the boom 2. The elastic layer 125 is made of rubber and has a thickness of 5mm.

[0038] During use, during the disassembly of boom 2, various operations may cause the rear boom 22 to sway, vibrate, or experience instantaneous impact. The elastic layer 125 is connected to the side of the lifting frame 123 near the rear boom 22. When the rear boom 22 comes into contact with the elastic layer 125, the elastic layer 125 can absorb and dissipate this energy by using its own elastic deformation, playing a role in buffering and shock absorption, reducing damage to the rear boom 22 and the moving support 12 itself, protecting the equipment and improving operational safety.

[0039] To drive the front arm 21 and the rear arm 22 to slide in opposite directions, please refer to... Figure 1 In a preferred embodiment, the drive mechanism 3 includes a hydraulic cylinder 31 and a hydraulic station 32. The outlet of the hydraulic station 32 is connected to the inlet of the hydraulic cylinder 31, and the outlet of the hydraulic cylinder 31 is connected to the inlet of the hydraulic station 32. The fixing mechanism 4 is used to connect the cylinder body of the hydraulic cylinder 31 to the front arm 21 of the boom 2, and the fixing mechanism 4 is used to connect the piston rod of the hydraulic cylinder 31 to the rear arm 22 of the boom 2.

[0040] In use, the drive mechanism 3 generates and regulates hydraulic energy through the hydraulic station 32, and then transmits the hydraulic energy to the hydraulic cylinder 31, so that the piston rod of the hydraulic cylinder 31 can extend and retract, thereby providing the required driving force for the disassembly of the boom 2.

[0041] To make the hydraulic cylinder 31 parallel to the boom 2, please refer to... Figure 3 In a preferred embodiment, the drive mechanism 3 further includes a leveling component 33, which is disposed on the hydraulic cylinder 31 and is used to make the hydraulic cylinder 31 parallel to the boom 2.

[0042] During use, the leveling component 33 adjusts the angle of the hydraulic cylinder 31, ultimately making the hydraulic cylinder 31 parallel to the boom 2, ensuring that the drive mechanism 3 can effectively apply force to the boom 2, and improving the accuracy and stability of the boom 2 disassembly work.

[0043] To adjust the cylinder body and piston rod of hydraulic cylinder 31 separately, please refer to... Figure 3In a preferred embodiment, the leveling assembly 33 includes a first support plate 331, a first bolt 332, a first nut 333, a second bolt 334, and a second support plate 335. The first support plate 331 is sleeved on the piston rod end of the hydraulic cylinder 31. The first support plate 331 has a strip hole 336. The piston rod has a through hole. The first bolt 332 passes through the strip hole 336 and the through hole. The first nut 333 is threaded to the end of the first bolt 332. The end of the first support plate 331 away from the piston rod abuts against the rear arm 22 of the boom 2. The second bolt 334 is threaded to the cylinder end of the hydraulic cylinder 31. The second support plate 335 is connected to the second bolt 334 and abuts against the front arm 21 of the boom 2.

[0044] In use, the first support plate 331 is fitted onto the piston rod end of the hydraulic cylinder 31. The piston rod has a through hole. The first bolt 332 passes through the slotted hole 336 of the first support plate 331 and the through hole on the piston rod. A first nut 333 is then threaded onto the end of the first bolt 332, connecting the first support plate 331 to the piston rod. When it is necessary to adjust the angle between the hydraulic cylinder 31 and the boom 2, the first nut 333 is loosened. Because the slotted hole 336 on the first support plate 331 is elongated, the first bolt 332 can move within the slotted hole 336. Based on the actual angular deviation between the hydraulic cylinder 31 and the boom 2, the position of the first bolt 332 in the slotted hole 336 is moved, thereby changing the height of the end of the first support plate 331 furthest from the piston rod. Because the end of the first support plate 331 furthest from the piston rod abuts against the rear boom 22, the first support plate 331 will cause the position of the rear boom 22 relative to the hydraulic cylinder 31 to change, thus fine-tuning the angle between the hydraulic cylinder 31 and the boom 2. After adjusting to the appropriate angle, tighten the first nut 333. The first nut 333 will fix the first bolt 332, thereby fixing the relative position between the first support plate 331 and the piston rod and maintaining the adjusted angle.

[0045] When fine-tuning the angle between the hydraulic cylinder 31 and the rear boom 22 using the first support plate 331, the first bolt 332, and the nut, the contact between the second support plate 335 and the front boom 21 plays a stabilizing and auxiliary positioning role. It ensures that the position of the cylinder end of the hydraulic cylinder 31 relative to the front boom 21 remains essentially unchanged, providing a relatively stable reference for the entire hydraulic cylinder 31 during adjustment. Simultaneously, by adjusting the screwing depth of the second bolt 334 at the cylinder end, the overall angle of the hydraulic cylinder 31 can also be adjusted to a certain extent, working in conjunction with the adjustment of the first support plate 331 to achieve parallelism between the hydraulic cylinder 31 and the boom 2.

[0046] To improve the stability of the first bolt 332 connection, please refer to... Figure 4In a preferred embodiment, the leveling component 33 further includes a shim 337, which is sleeved on the first bolt 332 and is located between the first support plate 331 and the first nut 333.

[0047] During use, the piston rod of the hydraulic cylinder 31 will be subjected to certain pressure and impact forces during operation, which will be transmitted to the first support plate 331 and the first nut 333. The gasket 337 has a certain degree of elasticity and can play a role in buffering pressure between the first support plate 331 and the first nut 333, reducing the deformation or damage of components caused by pressure and impact forces, and making the connection more reliable.

[0048] To achieve the pre-positioning of hydraulic cylinder 31, please refer to... Figure 5 In a preferred embodiment, the drive mechanism 3 further includes a locking block 34, which is connected to the cylinder body of the hydraulic cylinder 31 and is located at the locking position of the front section 21 of the boom 2.

[0049] During use, in the installation and commissioning phase, the locking block 34 is accurately connected to the cylinder body of the hydraulic cylinder 31, aligning it with the locking position on the front arm 21. At this time, the locking block 34 serves as an initial positioning element, determining the relative positional relationship between the hydraulic cylinder 31 and the front arm 21, providing a reference for subsequent work.

[0050] To secure the hydraulic cylinder 31 to the boom 2, please refer to... Figure 1 In a preferred embodiment, the fixing mechanism 4 includes a first binding rope 41 and a second binding rope. The first binding rope 41 is used to bind the cylinder body of the hydraulic cylinder 31 to the front section 21 of the boom 2, and the second binding rope is used to bind the piston rod of the hydraulic cylinder 31 to the rear section 22 of the boom 2.

[0051] In use, the first binding rope 41 binds the cylinder body of the hydraulic cylinder 31 to the front arm 21. Utilizing the rope's flexibility, it is wound and tightened around the cylinder body and front arm 21. During tightening, friction is generated between the rope and the surfaces of the cylinder body and front arm 21. This friction prevents relative displacement between the cylinder body and front arm 21, thus firmly fixing the cylinder body to the front arm 21. The second binding rope binds the piston rod of the hydraulic cylinder 31 to the rear arm 22, constraining the movement of the piston rod.

[0052] To better understand this utility model, the following is combined with... Figure 1 - Figure 5The working principle of a boom 2 disassembly fixture according to this utility model is described in detail below: A fixed bracket 11 is installed and supported on the front boom 21, and a movable bracket 12 is installed and supported on the rear boom 22. The fixed bracket 11 provides a relatively stable support foundation for the entire fixture, while the movable bracket 12 provides auxiliary support as the rear boom 22 moves, ensuring reliable support for both the front and rear booms 22 during disassembly and preventing them from swaying or tipping over. A fixing mechanism 4 securely fixes the fixed end of the drive mechanism 3 to one side of the front boom 21, while simultaneously fixing the movable end of the drive mechanism 3 to one side of the rear boom 22. The function of the fixing mechanism 4 is to ensure a reliable connection between the drive mechanism 3 and the front and rear booms 22, allowing the force generated by the drive mechanism 3 to be effectively transmitted to the front and rear booms 22. This gradually separates the front and rear booms 22, achieving the disassembly of the boom 2.

[0053] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model.
