[0025] Example

[0026] Reference Figure 1-4 This is an embodiment of the present invention, which provides an excavator boom adaptable to multiple excavator models, comprising:

[0027] The support assembly 100 includes a fastener 101, a bracket 102 mounted on the side wall of the fastener 101, a support plate 103 fixedly connected to the end of the bracket 102, and a connecting rod 104 fixedly connected to the side of the bracket 102. The bracket 102 is symmetrically mounted on both sides of the support plate 103, and the fastener 101 has an installation hole in the middle.

[0028] The boom assembly 200 includes a slide rail 201 fixedly connected to the side wall of the support plate 103, a slider 202 slidably mounted on the side wall of the slide rail 201, a mounting plate 203 fixedly connected to the end of the slider 202, a slide table 204 mounted on the side wall of the mounting plate 203, and a frame 205 fixedly connected to the end of the slide table 204. The frame 205 is symmetrically mounted on both sides of the mounting plate 203.

[0029] The support assembly 100, serving as the basic load-bearing structure of the boom, consists of a fixing member 101, a bracket 102, a support plate 103, and a connecting rod 104. The mounting hole in the center of the fixing member 101 allows for connection and fixation to the main structure of different excavator models, enabling boom installation compatibility across various models. The bracket 102 is symmetrically mounted on both sides of the support plate 103. This symmetrical structural design not only enhances the stability of the support plate 103 but also ensures balanced force distribution during the subsequent installation of the boom assembly 200. Simultaneously, the connecting rod 104, fixedly connected to the side of the bracket 102, further reinforces the frame structure of the entire support assembly 100, improving its resistance to deformation and load-bearing capacity, providing a solid foundation for the stable operation of the boom. The slide rail 201 in the boom assembly 200 is fixedly connected to the side wall of the support plate 103, and the slider 202 can slide along the side wall of the slide rail 201. This coordinated design provides smooth guidance for the extension and retraction of the boom, ensuring precise positioning and stable movement of the boom during operation. Meanwhile, the mounting plate 203 is fixedly connected to the end of the slider 202, the slide table 204 is installed on the side wall of the mounting plate 203, and the frame 205 is symmetrically installed on both sides of the mounting plate 203, together forming the main moving frame of the boom. In addition, the guide plate 210 fixedly connected to the middle side wall of the mounting plate 203 can be slidably inserted into the inner side of the groove in the middle of the support plate 103, forming a double guide, which further improves the stability and accuracy of the boom movement.

[0030] Specifically, the boom assembly 200 also includes a cylinder 206 fixedly connected to the lower side wall of the frame 205, and a gripper 207 fixedly connected to the output end of the cylinder 206. The end of the gripper 207 is provided with a bent edge structure. The boom assembly 200 also includes a push rod 208 threadedly connected to the side wall of the mounting plate 203. The end of the push rod 208 extends to the side wall of the gripper 207.

[0031] The cylinder 206, together with the gripper 207, constitutes the gripping mechanism of the boom. The bent edge structure at the end of the gripper 207 increases the contact area and friction with the object being gripped, improving the gripping firmness and reliability. By rotating the push rod 208, pressure can be applied to the gripper 207 to further adjust the clamping force, ensuring stable gripping of objects under different working conditions.

[0032] Furthermore, a connecting plate 209 is fixedly connected to the side wall of the mounting plate 203, and the end of the connecting plate 209 is snapped onto the cylinder 206.

[0033] It serves to limit and fix the cylinder 206, preventing it from shaking or shifting during operation and ensuring the stability and accuracy of the gripping action.

[0034] Furthermore, a guide plate 210 is fixedly connected to the middle side wall of the mounting plate 203. The guide plate 210 is slidably inserted into the inner side of the middle groove of the support plate 103. The boom assembly 200 also includes a motor 213 fixedly connected to the side wall of the support plate 103, a lead screw 214 fixedly connected to the end of the output shaft of the motor 213, a ball nut 215 adapted to be installed in the middle of the lead screw 214, and a connector 216 fixedly connected to the end of the ball nut 215. The end of the connector 216 is fixedly connected to the end of the guide plate 210 by bolts.

[0035] The rotational motion of the motor 213, combined with the lead screw 214, is converted into the linear motion of the ball nut 215. This motion, in turn, drives the boom assembly 200 to perform precise telescopic movements along the slide rail 201 via the guide plate 210, thereby enabling flexible adjustment of the boom's working range.

[0036] Preferably, the boom assembly 200 also includes a stop 211 fixedly connected to the side wall of the mounting plate 203, and a limiting block 212 fixedly connected to the side wall of the frame 205, the limiting block 212 and the stop 211 working together.

[0037] The stop block 211, which is fixedly connected to the side wall of the mounting plate 203, works in conjunction with the limit block 212, which is fixedly connected to the side wall of the frame 205. By setting a reasonable limit distance, the movement range of the boom assembly 200 is limited, preventing the boom from exceeding the safe stroke during operation and avoiding mechanical failures and safety accidents.

[0038] When using the excavator boom, first, according to the structural characteristics of different excavator models, install the support assembly 100 onto the excavator body through the mounting hole in the middle of the fixing part 101 to complete the basic fixing of the boom.

[0039] When gripping an object, cylinder 206 is activated. The output end of cylinder 206 drives the gripper 207 to extend, and the bent edge structure at the end of the gripper 207 contacts and grips the object. Depending on the weight and shape of the object, the pressure of the push rod 208 on the gripper 207 can be adjusted by rotating the push rod 208 on the side wall of the mounting plate 203 to ensure that the gripper 207 can firmly grip the object. The connecting plate 209 on the side wall of the mounting plate 203 limits and fixes cylinder 206, ensuring the stability of cylinder 206 during operation, thereby ensuring the accurate execution of the gripping action of the gripper 207.

[0040] During the extension and retraction of the boom, motor 213 is started. The output shaft of motor 213 drives the lead screw 214 to rotate. The lead screw 214, through its cooperation with the ball nut 215, converts the rotational motion into the linear motion of the ball nut 215. The ball nut 215 drives the guide plate 210 to move through the connector 216, thereby driving components such as the mounting plate 203, slide table 204, and frame 205 to extend and retract along the slide rail 201. During this process, the cooperation between the slide rail 201 and the slider 202, as well as the cooperation between the guide plate 210 and the intermediate groove of the support plate 103, jointly ensure the stable and precise movement of the boom assembly 200. When the boom assembly 200 moves to the predetermined position, the stop block 211 on the side wall of the mounting plate 203 and the limiting block 212 on the side wall of the frame 205 cooperate to restrict the further movement of the boom assembly 200, ensuring that the boom operates within the safe travel range.

[0041] In summary, the mounting hole design of the fixing member 101 in the support assembly 100 allows the excavator boom to be connected and fixed with various excavator bodies without requiring large-scale modifications to the excavator body, greatly improving the boom's versatility and applicability, and reducing the operating and maintenance costs of the excavator equipment. The cylinder 206 in the boom assembly 200, in conjunction with the gripper 207, and the bent edge structure at the end of the gripper 207 and the pressure adjustment function of the push rod 208, can firmly grasp objects of different shapes and weights. The clamping force can be flexibly adjusted according to actual working conditions, ensuring that objects will not fall during excavation and handling operations, thus improving operational safety and efficiency. The dual guiding structure of the slide rail 201 and the slider 202, the guide plate 210 and the support plate 103, and the precise drive structure of the motor 213, lead screw 214, and ball nut 215 enable precise positioning and stable operation of the boom during extension, retraction, and movement, effectively reducing boom sway and deviation, and improving the accuracy and quality of excavation operations. The combined use of stop block 211 and limit block 212 restricts the movement range of boom assembly 200, prevents the boom from exceeding the safe stroke, avoids mechanical failures and safety accidents caused by excessive boom movement, and ensures the personal safety of excavator operators and the normal operation of equipment.
