Description

Technical Field

[0001] This utility model relates to the field of gate wheel axles, and in particular to a positioning mechanism for disassembling gate wheel axles. Background Technology

[0002] This is a comprehensive technical solution and equipment combination used to ensure operational safety and accuracy when disassembling gate axles (or axle sleeves). It is based on hydraulic support, uses mechanical limiters, locating pins or special clamps to achieve precise fixation, and is further calibrated by precision measurement. Ultimately, it ensures that the axle can be safely and accurately disassembled, laying the foundation for subsequent installation or replacement work.

[0003] In related technologies, gate axle disassembly is a professional operation in mechanical maintenance. It mainly involves the process of separating the axle components on the gate from the overall structure. Due to the large size of the gate axle, it usually needs to be lifted by a hoisting mechanism. However, during the hoisting process, since there is no mechanism to position the end of the axle, the axle is prone to shaking during hoisting, which affects the stability of the hoisting operation.

[0004] This method has obvious drawbacks: it cannot accurately position the axle and requires constant adjustment of its position via a hoisting mechanism. Utility Model Content

[0005] The main purpose of this utility model is to provide a positioning mechanism for disassembling gate wheel axles, thereby solving the problem of inaccurate wheel axle positioning.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a positioning mechanism for disassembling a gate wheel axle, comprising: The support base has two spaced apart, and a mounting seat is movably provided between the tops of the support base; The clamping seats each have an arc-shaped groove on their corresponding surfaces. A protective pad is fixedly installed in each arc-shaped groove. The two clamping seats are movably connected to the inner wall of the mounting seat with their sides away from the arc-shaped grooves. The arc-shaped grooves in the two clamping seats are used to clamp the wheel axle. An electric hydraulic cylinder is located on the side away from the arc-shaped groove and is fixedly mounted on the mounting base. The electric hydraulic cylinder is used to adjust the relative translation of the two clamping seats.

[0007] In the preferred embodiment, the bottom of each of the two support seats is provided with a first base, and a second base is fixedly provided between the two first bases. The top of the support seat and the rotating seat are detachably connected, and the mounting seat is movably located between the two rotating seats.

[0008] In the preferred embodiment, an auxiliary groove and a guide groove are respectively provided on one side of the two clamping seats. One end of the guide post is fixed to the inner wall of the mounting seat, and the other end is movably sleeved in the guide groove. The extended end of the electric hydraulic cylinder is fixed in the auxiliary groove.

[0009] In the preferred embodiment, the two clamping seats are respectively fixedly connected to the sides of the connection, and the connecting parts are connected by a first fixing bolt.

[0010] In the preferred embodiment, a first mounting component is fixedly provided on the top of the support base, and a second mounting component is provided on the bottom of the rotating base. The first mounting component is connected to the second mounting component by a second fixing bolt.

[0011] In the preferred embodiment, a first reinforcing member is fixedly provided at the included angle between the support base and the first base.

[0012] In the preferred embodiment, a second reinforcing member is fixedly provided at the included angle between the support base and the second base.

[0013] In the preferred embodiment, a third reinforcing member is fixedly provided at the included angle between the first base and the second base.

[0014] In the preferred embodiment, each of the two rotating seats has a rotating shaft on its corresponding surface, and the rotating shaft is used to rotatably connect to the outer wall of the mounting seat.

[0015] In the preferred embodiment, fixing holes are provided on both sides of the first base.

[0016] The beneficial effects of this utility model's positioning mechanism for disassembling gate wheel axles are as follows: 1. The electric hydraulic cylinder serves as the core drive mechanism, precisely controlling the movement and clamping force of the clamping seats. This ensures synchronized operation of both clamping seats during the advancement process, preventing wheel and axle deformation or clamping failure due to uneven force. The inner arc-shaped groove of the clamping seat is equipped with a protective pad adapted to the outer diameter of the wheel and axle, and can be fitted with an anti-slip and wear-resistant liner to increase friction and protect the wheel and axle surface. The entire clamping process is highly automated, safe, and reliable, effectively adapting to the disassembly requirements of wheel and axle of different specifications, significantly improving work efficiency and safety. 2. After clamping the axle, considering potential spatial angle differences in the valve system during initial installation, the clamping mechanism can be circumferentially adjusted via a rotating mounting seat. This allows the clamping seat to rotate flexibly to the required angle and lock securely. This design effectively adapts to spatial positioning requirements under complex working conditions, suppressing axle swaying and twisting during crane lifting, ensuring a smooth and precise disassembly process, avoiding damage to the valve body or other connecting components, and greatly improving operational controllability and safety.

[0020] Furthermore, the support base 3 is provided with two spaced-apart rotating bases 7, each detachably connected to its top. A mounting base 9 is rotatably connected between the two rotating bases 7. Two clamping bases 10 are movably positioned between the inner walls of the mounting bases 9. Each clamping base 10 has an arc-shaped groove 1001 on its corresponding surface. The arc-shaped groove 1001 is used to clamp the wheel axle and limit its position. Wheel axles are generally used in gates. An electric hydraulic cylinder 11 is fixedly connected to the corresponding side of the rotating base 7, and its extended end is fixed to one side of the two clamping bases 10. The electric hydraulic cylinder 11 is used to adjust the relative translation of the two clamping bases 10 and clamps the wheel axle through the arc-shaped groove 1001 on the opposite surface of the clamping bases 10. A protective pad 13 is provided on the arc-shaped groove 1001, and the protective pad 13 is used to protect the wheel axle. The electric hydraulic cylinder 11 serves as the driving core, precisely controlling the travel and clamping force of the clamping seat 10. This ensures that the two clamping seats 10 on both sides maintain synchronous operation during the advancement process, preventing wheel axle deformation or clamping failure due to uneven force. The arc-shaped groove 1001 on the inner side of the clamping seat 10 is equipped with a protective pad 13 adapted to the outer diameter of the wheel axle, and an anti-slip and wear-resistant liner can be added to increase friction and protect the wheel axle surface.

[0021] The bottom of each of the two support seats 3 is provided with a first base 1, and a second base 2 is fixedly provided between the two first bases 1.

When the two clamping seats 10 need to clamp or release the wheel axle, the electric hydraulic cylinder 11 is activated and drives the two clamping seats 10 to translate relative to each other, and the two clamping seats 10 are translated along the guide post 12. The guide post 12 can prevent the two clamping seats 10 from deviating during the translation process and accurately position them.
