Abstract
Description
Technical Field
[0001] This utility model relates to the field of electrical engineering technology, and more specifically, to a detachable current collector contact shoe. Background Technology
[0002] Current collector contact shoes are key components for current conduction in rail transportation, industrial mobile equipment (such as cranes and electric vehicles), and other fields. They transfer electrical energy from a fixed power source to the mobile equipment through sliding contact with conductive rails, sliding contact lines, and other electrical connection devices. Their performance directly affects the conductivity stability, equipment operational reliability, and service life. Therefore, strict requirements are placed on the contact shoe's contact adaptability (such as adapting to uneven contact surfaces), reset capability (such as returning to the initial position after external force), and maintenance convenience (such as component replacement efficiency).
[0003] Traditional current collector contact shoes mostly use rigid connections or simple elastic structures, which have the following shortcomings: First, they have poor deflection flexibility, only able to achieve small-angle deflection in one direction, making it difficult to adapt to uneven conditions such as local protrusions and depressions on the surface of the connecting device, which can easily lead to poor contact or local wear. Second, they have insufficient reset stability, and when relying on a single spring for reset, they are prone to reciprocating bounce due to the release of elastic force, causing the contact shoe to frequently detach from the connecting device, affecting the continuity of conductivity. Third, they have a high degree of structural integration, with the contact shoe and connecting components mostly fixed connections. After damage, the entire device needs to be disassembled and replaced, resulting in high maintenance costs and long maintenance time, which affects the continuous operation of the equipment. Utility Model Content
[0004] In view of the problems in the related technologies, this utility model proposes a detachable current collector contact shoe to overcome the above-mentioned technical problems existing in the existing related technologies.
[0005] Therefore, the specific technical solution adopted by this utility model is as follows:
[0006] A detachable current collector contact shoe includes a current collector plate, a docking block rotatably connected to the current collector plate, a deflection structure rotatably connected to the docking block, a connecting structure rotatably connected to the deflection structure, a contact shoe structure connected to the connecting structure, and a damping rod connected between the deflection structure and the current collector plate. The current collector contact shoe, composed of the deflection structure, the connecting structure, the contact shoe structure, and the damping rod, realizes the deflectable transmission function with the docking block and the current collector plate.
[0007] Furthermore, the deflection structure includes a connecting crossbar, a connecting hole, a limiting block, a connecting piece, and a connecting hook. A connecting hole is provided on one side of the connecting crossbar, and a limiting block is fixedly provided on the other side of the connecting crossbar. A connecting hook is fixedly provided on one side of the limiting block. A connecting pin is provided between the limiting block and the connecting hook to rotatably connect with the docking block. The limiting block is connected to the docking block by a spring. Ball head supports are provided at both ends of the damping rod, and the damping rod is connected between the connecting crossbar and the current collector piece by the ball head supports.
[0008] Furthermore, the connecting structure includes a connecting block, a fixing hole, a mounting crossbar, and a limiting connecting seat. The connecting block is provided with a fixing hole, and a mounting crossbar is rotatably connected to one side of the connecting block. A limiting connecting seat is fixedly connected to the mounting crossbar. The limiting connecting seat of the mounting crossbar is connected to the connecting hook of the deflection structure through a spring. The connecting block is connected to the limiting connecting seat through a spring, and the limiting connecting seat is connected to the bottom end of the limiting block through a spring.
[0009] Furthermore, the contact shoe structure includes a contact shoe plate, a contact shoe end, and a connecting rod. The contact shoe plate has a contact shoe end at its bottom end, and a connecting rod is hinged to the contact shoe plate. The contact shoe plate is fixedly connected to the connecting block by a fixing pin.
[0010] The beneficial effects of this utility model are as follows:
[0011] 1. Through the multi-node rotational connection of the deflection structure and the connection structure, the contact shoe structure can achieve multi-angle deflection, which can adapt to the unevenness of the surface of the power receiving device, ensure stable contact between the contact shoe end and the power receiving device, and avoid poor contact caused by local unevenness.
[0012] 2. The deflection structure is connected to the docking block via a spring, and the connecting structure is connected to the deflection structure and the contact shoe structure via springs respectively, forming a multi-directional elastic reset system. Combined with the damping energy dissipation function of the damping rod, it effectively suppresses the reciprocating bouncing phenomenon during traditional single spring reset, ensuring that the contact shoe structure quickly and stably returns to its initial position after deflection, thus improving the continuity of conductivity.
[0013] 3. The rotating connections of each structure reduce rigid impact, and the synergistic effect of the spring and damping rod reduces the contact stress and wear rate between the contact shoe end and the electrical connection device. At the same time, the limiting block, limiting connection seat and other structures constrain the deflection angle, avoid damage to components caused by excessive deflection, and further extend the overall service life of the device.

[0023] 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.
[0024] According to an embodiment of the present invention, a detachable current collector contact shoe is provided.
[0025] like Figure 1-6 As shown, the detachable current collector contact shoe according to an embodiment of the present invention includes a current collector plate 1, a docking block 2 rotatably connected to the current collector plate 1, a deflection structure 3 rotatably connected to the docking block 2, a connecting structure 4 rotatably connected to the deflection structure 3, a contact shoe structure 5 connected to the connecting structure 4, and a damping rod 6 connected between the deflection structure 3 and the current collector plate 1. The current collector contact shoe composed of the deflection structure 3, the connecting structure 4, the contact shoe structure 5, and the damping rod 6 realizes the deflectable transmission function with the docking block 2 and the current collector plate 1.
[0026] The current collector plate 1, as the basic structure of the entire detachable current collector shoe, plays a crucial role in connecting to external conductive devices, providing a conductive path and mounting carrier for the device. Through its rotatable connection with the docking block 2, the current collector plate 1 provides a fixed support point for the deflection action of the subsequent deflection structure 3, connecting structure 4, and shoe structure 5. Simultaneously, as one of the connection ends of the damping rod 6, it works in conjunction with the damping rod 6 to achieve damping and buffering control of the deflection structure 3, ensuring the stability of the entire device during the conductive process.
[0027] The docking block 2 is a key intermediate structure connecting the current collector 1 and the deflection structure 3. Through its rotational connection with the current collector 1, it provides a rotational fulcrum for the deflection structure 3 relative to the current collector 1. At the same time, the limiting block 303 of the deflection structure 3 is connected to the docking block 2 through a spring, so that the deflection structure 3 has an elastic reset basis after deflection. In addition, the connecting pin of the docking block 2 and the deflection structure 3 cooperates to form the axis of rotation of the deflection structure 3, ensuring that the deflection structure 3 can achieve stable angle adjustment around the docking block 2, thereby driving the downstream connecting structure 4 and the contact shoe structure 5 to deflect synchronously.
[0028] The deflection structure 3 includes a connecting crossbar 301, a connecting hole 302, a limiting block 303, a connecting piece 304, and a connecting hook 305. The connecting crossbar 301 has a connecting hole 302 on one side and a limiting block 303 fixedly on the other side. A connecting hook 305 is fixedly provided on one side of the limiting block 303. A connecting pin that is rotatably connected to the docking block 2 is provided between the limiting block 303 and the connecting hook 305. The limiting block 303 is connected to the docking block 2 by a spring. The damping rod 6 has ball head supports at both ends and is connected between the connecting crossbar 301 and the current collector piece 1 by the ball head supports.
[0029] The deflection structure 3 is the core structure for realizing the deflection function of the device. Its connecting crossbar 301 serves as the main frame. One side is connected to the connecting rod 503 of the contact shoe structure 5 through the connecting hole 302, allowing the contact shoe structure 5 to rotate relative to the deflection structure 3. The other side is connected to the docking block 2 through the limiting block 303, and the spring of the limiting block 303 forms an elastic reset system with the docking block 2. The connecting hook 305 is connected to the limiting connecting seat 404 of the connecting structure 4 through a spring, further enhancing the reset capability after deflection. At the same time, the connecting crossbar 301 is connected to the current collector 1 through the damping rod 6. The ball head support design of the damping rod 6 allows it to adapt to the multi-angle rotation of the connecting crossbar 301. During the deflection process, the damping energy dissipation function absorbs the excess energy when the spring resets, preventing the spring from bouncing back and forth and improving the sliding stability of the contact shoe device.
[0030] The connecting structure 4 includes a connecting block 401, a fixing hole 402, a mounting crossbar 403, and a limiting connecting seat 404. The connecting block 401 is provided with a fixing hole 402. The mounting crossbar 403 is rotatably connected to one side of the connecting block 401. The limiting connecting seat 404 is fixedly connected to the mounting crossbar 403. The limiting connecting seat 404 of the mounting crossbar 403 is connected to the connecting hook 305 of the deflection structure 3 through a spring. The connecting block 401 is connected to the limiting connecting seat 404 through a spring. The limiting connecting seat 404 is connected to the bottom end of the limiting block 303 through a spring.
[0031] The connecting structure 4 is a transitional structure connecting the deflection structure 3 and the contact shoe structure 5. Its connecting block 401 is fixedly connected to the contact shoe piece 501 of the contact shoe structure 5 through a fixing pin, providing an installation base for the contact shoe structure 5. The fixing hole 402 is used for the stable installation of the connecting block 401. The mounting crossbar 403 is rotatably connected to the connecting block 401. The limiting connecting seat 404 on it is connected to the connecting hook 305 of the deflection structure 3, the connecting block 401 and the bottom end of the limiting block 303 of the deflection structure 3 through springs, forming a multi-directional elastic constraint system. When the contact shoe structure 5 is deflected by an external force, the limiting connecting seat 404 transmits the tension to the connecting hook 305 and the limiting block 303 through the spring, which, together with the spring of the deflection structure 3, realizes the coordinated reset of the contact shoe structure 5 in the horizontal and vertical directions, ensuring that it can quickly return to the initial position after deflection.
[0032] The contact shoe structure 5 includes a contact shoe piece 501, a contact shoe end 502, and a connecting rod 503. The contact shoe piece 501 has a contact shoe end 502 at its bottom end, and the connecting rod 503 is hinged on the contact shoe piece 501. The contact shoe piece 501 is fixedly connected to the connecting block 401 by a fixing pin.
[0033] The contact shoe structure 5 is the actuation structure for the device to contact the external power receiving device. Its contact shoe end 502 is directly slidably connected to the power receiving device to realize the conduction of current. The contact shoe piece 501, as the carrier of the contact shoe end 502, is detachably connected to the connecting block 401 of the connecting structure 4 through a fixing pin, which is convenient for later maintenance and replacement. The connecting rod 503 hinged on the contact shoe piece 501 is limited to the connecting hole 302 of the deflection structure 3 for rotational limitation, so that the contact shoe structure 5 can rotate around the connecting rod 503 relative to the deflection structure 3. With the spring and damping system of the connecting structure 4 and the deflection structure 3, the contact shoe end 502 can adaptively adjust to the unevenness of the contact surface during the sliding process, ensuring stable contact with the power receiving device and improving the reliability of conductivity.
[0034] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.
[0035] The current collector 1 is connected to the conductive device. The contact shoe end 502 of the contact shoe structure 5 is slidably connected to the receiving device. The deflection structure 3, the connecting structure 4, the contact shoe structure 5, and the damping rod 6 form a current collector contact shoe device that is connected to the current collector 1 and the docking block 2, thereby enabling the current collector 1 and the contact shoe device to have a certain deflection function and an automatic reset function, improving the sliding connection stability of the contact shoe device. The connecting crossbar 301 of the deflection structure 3 is connected to the docking block 2 through the damping rod 6. The connecting crossbar 301 and the docking block 2 are rotatably connected. The damping rod 6 enables the connecting crossbar 301 to have a certain rotation angle with respect to the docking block 2 while also providing a certain degree of rotation. The damping energy dissipation function prevents the spring from bouncing back and forth. The connecting block 401 of the connecting structure 4 is fixedly connected to the contact shoe piece 501 by a fixing pin. The connecting block 401 and the contact shoe piece 501 are detachably connected. The connecting hole 302 of the deflection structure 3 is limited to the rotating connection of the connecting rod 503 of the contact shoe structure 5, so that the contact shoe structure 5 and the deflection structure 3 have a rotation function. At the same time, the limiting connecting seat 404 of the connecting structure 4 has a limiting function through the spring connection with the connecting hook 305, the connecting block 401, and the spring connection of the docking block 2, so that after the relative deflection between the contact shoe structure 5 and the deflection structure 3 occurs, it can freely reset after being free from external force.
[0036] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
