Description

Technical Field

[0001] This utility model relates to the field of pantograph technology, and in particular to a quick-release pantograph. Background Technology

[0002] As a core component of the traction power supply system, the pantograph-catenary system in high-speed railways directly affects the train's operational safety and current collection quality through its mechanical structure design and dynamic performance. In recent years, with the breakthrough increase in train operating speeds, the pantograph-catenary system faces more complex mechanical structural challenges under high-speed dynamic coupling. Existing research indicates that dynamic contact force fluctuations between the pantograph's sliding contact plate and the contact wire, the nonlinear vibration characteristics of the pantograph head suspension mechanism, and the matching of spatial geometric parameters of the contact wire suspension system have become key factors restricting the mechanical stability of the pantograph-catenary system.

[0003] Currently, maintaining and replacing the pantograph head takes a lot of time; therefore, there is an urgent need for a quick-release pantograph that can be disassembled and assembled without tools, effectively shortening the replacement time of the pantograph head. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] Reference Figures 1-7 This utility model discloses a quick-release pantograph, including quick-release components symmetrically arranged at the bottom of the pantograph head 3 for installation and removal of the pantograph head 3. The quick-release components include a first connecting portion installed at the bottom of the pantograph head 3, the first connecting portion including a connecting block 1 fixedly connected to the pantograph head 3, and a second connecting portion detachably connected to the connecting block 1 via a first slider 11. The second connecting portion includes a base 2, and a second slider 22 is fixedly connected to the base 2 via a limiting member. The second slider 22 is detachably connected to the first slider 11. The second slider 22 is mounted on a bracket.

[0028] This utility model uses a limiting member to drive the second slider 22 to rotate, so that the second slider 22 can lock the first slider 11. By rotating the limiting member in the opposite direction, the second slider 22 can be separated from the first slider 11. This not only enables tool-free disassembly and assembly, but also facilitates the quick disassembly and assembly of the bow head 3.

[0029] In a further optimized design, a groove 12 is provided at the end of the first slider 11 facing the second slider 22, and the groove 12 is detachably connected to the second slider 22. When the second slider 22 is inserted into the groove 12, the first slider 11 and the second slider 22 are connected; when the second slider 22 is separated from the groove 12, the first slider 11 and the second slider 22 are separated.

[0030] In a further optimized design, the second slider 22 is adapted to the slide groove 12. This allows the second slider 22 to slide effectively within the slide groove 12, facilitating its insertion into or removal from the slide groove 12.

[0031] The design was further optimized so that the base 2 is U-shaped. This allows the limiting member to rotate effectively within the base 2 and the first slider 11 to be effectively installed within the base 2.

[0032] A further optimized design includes a limiting component comprising a rotating shaft 21 rotatably connected within the base 2, and the rotating shaft 21 being fixedly connected to the second slider 22. The rotating shaft 21 drives the second slider 22 to rotate, allowing the second slider 22 to insert into the slide groove 12, and the reverse rotation of the rotating shaft 21 causes the second slider 22 to separate from the slide groove 12.

[0033] In a further optimized design, a fixing block 23 is fixedly connected to one end of the rotating shaft 21 extending outside the base 2, and a limiting disk 25 is fixedly connected to the other end of the rotating shaft 21 extending outside the base 2. A handle 24 is rotatably connected to the fixing block 23. By rotating the handle 24 on the fixing block 23, it is easy to flip the handle 24 and move it away from the outer wall of the base 2, thereby effectively driving the rotating shaft 21 to rotate.

[0034] The design is further optimized by attaching a buckle to the handle 24. The buckle is detachably connected to a slot, which is located on the base 2.

[0035] The buckle is made of spring steel and the slot is wedge-shaped, which allows the buckle to engage precisely with the slot.

[0036] After the second slider 22 is inserted into the slide groove 12, the handle 24 is flipped so that the buckle is in the slot, which limits the handle 24 and ensures that the second slider 22 is stably and effectively in the slide groove 12, effectively preventing the second slider 22 from sliding out of the slide groove 12.

[0037] The design was further optimized so that the length of the fixing block 23 and the outer diameter of the limiting disk 25 are both greater than the outer diameter of the rotating shaft 21. This allows the rotating shaft 21 to rotate stably within the base 2.

[0038] In a further optimized design, the base 2 and the connecting block 1 are magnetically connected on opposite sides via permanent magnets. The permanent magnets are high-strength neodymium iron boron permanent magnets, and the base 2 and the connecting block 1 are made of magnetic conductors, enabling the base 2 and the connecting block 1 to provide axial holding force through magnetic attraction.

[0039] Working process: During assembly, the magnetic force of the permanent magnet guides the pre-positioning of the connecting block 1, placing the first slider 11 within the base 2 and aligning the slide groove 12 with the second slider 22, effectively eliminating manual alignment errors. Then, rotating the handle 24 drives the fixed block 23 to rotate, which in turn drives the rotating shaft 21 to rotate. The rotating shaft 21 then causes the second slider 22 to engage in the slide groove 12. In other words, rotating the handle 24 drives the second slider 22 to complete a 1 / 4 circular motion. When the handle 24 rotates to the predetermined angle... When the second slider 22 is inserted into the groove 12 along the spiral trajectory, the self-locking characteristic of the wedge structure of the second slider 22 and the groove 12 is used to achieve initial fixation. Then, the buckle of the handle 24 and the slot on the base 2 form a mechanical interlock. That is, after the second slider 22 is inserted into the groove 12, the operator completes the rotation of the handle 24 along the fixed block 23 and then presses down the buckle of the handle 24 to engage with the slot. The second slider 22 and the groove 12, as well as the buckle and the slot, can effectively form a double safety guarantee.

[0040] This invention can effectively achieve quick assembly and disassembly of the bow head 3 without tools; the plate-shaped handle 24 drives the rotating shaft 21 to rotate, which drives the quarter-cylindrical second slider 22 to move radially along the arc-shaped slide of the slide groove 12. When the second slider 22 is inserted into the slide groove 12, the initial positioning is completed by the self-locking principle of the second slider 22 and the inclined surface of the slide groove 12; at the same time, when the handle 24 is rotated to a predetermined angle, pressing the handle 24 makes the spring steel buckle precisely engage with the wedge groove of the base 2. At the same time, the high-strength neodymium iron boron permanent magnet and the magnetic conductor generate axial attraction force, forming a dual action to form a stable constraint.
