Description

Technical Field

[0001] This utility model relates to the technical field of graphitization furnace rectifier units, and in particular to a lifting power transmission vehicle. Background Technology

[0002] A power transmission vehicle is a mobile device that draws power from the power supply busbar and supplies power to the graphitization furnace. The power transmission vehicle is equipped with an electrode clamping mechanism and a busbar clamping mechanism that are electrically connected to each other. Conductive electrodes are installed on both end walls of the graphitization furnace. When power is supplied, the power transmission vehicle connects to the conductive electrodes via the electrode clamping mechanism and to the power supply busbar via the busbar clamping mechanism.

[0003] In a specific scenario, when the drive cylinder pushes the electrode clamping mechanism to rise, the stopping position of the power supply vehicle fails to fully align with the furnace position of the graphitization furnace, resulting in inaccurate docking between the electrode clamping mechanism and the conductive electrode. This leads to easy damage to the conductive electrode and poor power supply stability of the power supply vehicle.

[0004] Therefore, it is urgent to propose a new technical solution to address the problem. Utility Model Content

[0034] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings; many specific details are set forth in the following description in order to provide a full understanding of this utility model; based on the embodiments of this utility model, those skilled in the art can make similar improvements without departing from the spirit of this utility model, but cannot make all other embodiments obtained without creative effort, therefore this utility model is not limited to the specific embodiments disclosed below.

[0035] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal connection of two components; and they can also refer to a "transmission connection," that is, a power connection through various suitable methods such as belt drive, gear drive, or sprocket drive. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0036] Please see Figures 1 to 6 To address the problem of poor stability of the power transmission vehicle caused by inaccurate docking between the electrode clamping mechanism and the conductive electrode, this utility model provides a lifting power transmission vehicle 100, which includes: a vehicle body 10, on which a gantry 11 is provided; a lifting mechanism 20, on which a flexible connecting component 30 is connected, the flexible connecting component 30 being connected to the lifting mechanism 20 via a chain 34; and a conductive mechanism 40, which includes an electrode clamping mechanism 41 and a busbar clamping mechanism 42, the busbar clamping mechanism 41 being connected to the electrode clamping mechanism 42, the electrode clamping mechanism 41 being connected to the flexible connecting component 30, and rising and falling under the drive of the lifting mechanism 30. This invention provides a lifting mechanism 20 on the trolley 100, and connects the lifting mechanism 20 to the flexible connection component 30. When the lifting mechanism 20 pulls the electrode clamping mechanism 41 upward, if it is found that the electrode clamping mechanism 41 is not properly aligned with the conductive electrode, the flexible connection component 30 causes the electrode clamping mechanism 41 to shake adaptively, ensuring the precise alignment of the electrode clamping mechanism 41 with the conductive electrode and improving the stability of the trolley 100.

[0037] Please see Figures 1 to 2 In one embodiment, the vehicle body 10 includes a main frame 12 and an extension frame 13. Two drive motors 121 and two drive wheels 122 are provided on one side of the main frame 12. The two drive motors 121 are respectively connected to the two drive wheels 122. The drive motors 121 are used to provide kinetic energy to the drive wheels 122 to drive the entire vehicle body 10 to move.

[0038] An extension frame 13 is located on one side of the main frame 12 opposite to the drive wheel 121 and extends downward from the main frame 12. Two driven wheels 131 are mounted on the extension frame 13 and move under the drive of the drive wheel 121. Furthermore, since the driven wheels 131 are located on the extension frame 13, they are not on the same horizontal plane as the two drive wheels 121. Specifically, when the terrain on one side of the driven wheels 131 is lower, the driven wheels 131 are much lower than the height of the drive wheels 122.

[0039] This application adds an extension frame 13 to the main frame 12 and places the driven wheel 131 on the extension frame 13. This allows the height of the driven wheel 131 to be flexibly adjusted according to the actual terrain, so that the trolley 100 can adapt to uneven terrain. The trolley 100 runs stably and reliably, is not easy to overturn, and has strong safety.

[0040] Specifically, the main frame 12 is a hollow frame, and the hollow part of the hollow frame is used for the conductive mechanism 40 to pass through so that the conductive mechanism 40 can be connected to the power supply busbar laid on the ground.

[0041] Please see Figure 4 and Figure 6 In one embodiment, the gantry 11 includes two side frames 111 and a top frame 112 fixedly disposed on the two side frames 111. The lifting mechanism 20 is disposed on the top frame 112.

[0042] In this embodiment, the power supply vehicle 100 employs a gantry 11, which provides ample space below the gantry 11 for the conductive mechanism 40, allowing the conductive mechanism 40 to be fixed in an inverted manner. Furthermore, the side frame 111 is used to increase the installation height of the top frame 112, which provides an installation position for the lifting mechanism 20, saving space in the vehicle body 10.

[0043] Please see Figure 2 and Figure 5 In one embodiment, the extended frame 13 includes a support frame 132 and a frame column 133. The frame column 133 extends downward from the main frame 12, and the support frame 132 is provided at one end of the frame column 133 relative to the main frame 12. The driven wheel 131 is rotatably mounted on the support frame 132. There can be one or more frame columns 133 to make the force on the vehicle body 10 more even and improve the stability of the trolleybus 100 operation.

[0044] Furthermore, the frame column 133 can be configured to be detachably connected to the main frame 12 and detachably connected to the support frame 132. Exemplarily, flanges (not shown) are provided on both the main frame 12 and the frame column 133, and screws are inserted through the flanges of the main frame 12 and the frame column 133 to achieve relative fixation between the main frame 12 and the frame column 133. Correspondingly, flanges are provided on both the support frame 132 and the frame column 133, and screws are inserted through the flanges of the support frame 132 and the frame column 133 to achieve relative fixation between the extension frame 13 and the frame column 133.

[0045] The frame column 133 is detachably connected to the main frame 12, and the frame column 133 is detachably connected to the support frame 132. This allows for the selection of a suitable height for the frame column 133 based on the actual terrain, providing high flexibility and improving transportation and assembly efficiency.

[0046] Of course, the frame column 133 and the main frame 12 can be configured to be fixedly connected, and the frame column 133 and the extension frame 13 can be configured to be fixedly connected, without being limited to the specific limitations of this embodiment.

[0047] Of course, the body 10 of the electric vehicle 100 can also be configured such that the driving wheel 122 and the driven wheel 131 are on the same horizontal plane, such as when there is only the main frame 12 and no extension frame 13, which is not limited to the specific implementation of this case.

[0048] Please see Figure 3 , Figure 5 and Figure 6 In one embodiment, the lifting mechanism 20 includes: two drive cylinders 21, a synchronous connecting rod 22, a fixed pulley 23 and a chain 24. The synchronous connecting rod 22 connects the two drive cylinders 21, and the chain 24 is connected to the conductive frame 41 of the conductive mechanism 40 after passing through the fixed pulley 23. The two drive cylinders 41 are symmetrically distributed on the left and right sides of the top frame 112.

[0049] In another embodiment, the lifting mechanism 20 can also be configured as a drive cylinder 21, a fixed pulley 23, and a chain 24. In this embodiment, the drive cylinder 21 is arranged at the center of the top frame 111, and the output shaft of the drive cylinder 21 is connected to the chain 24. The chain 24 is guided by the fixed pulley 23 and then connected to the conductive frame 41 of the conductive mechanism 40. The fixed pulley 23 is fixedly mounted on the flexible connection assembly 30. That is, the lifting mechanism 40 is a single-cylinder lifting mechanism 40, which does not require a synchronous connecting rod 42, and has a simple and compact structure.

[0050] However, in practice, the applicant found that using only one drive cylinder 41 resulted in a large local load at the contact point between the drive cylinder 41 and the top frame 112. To prevent the top frame 112 from breaking due to excessive stress, it was often necessary to make the top frame 112 very thick to increase its mechanical strength, which greatly increased the cost of use.

[0051] In this embodiment, the lifting mechanism 20 adopts two driving cylinders 21, which are arranged on the left and right sides of the top frame 22 to share the load brought by the conductive mechanism 40. This can greatly reduce the local load on the driving cylinders 21 and the top frame 112, and has a wider range of applications.

[0052] Synchronizing link 22 is connected to the output shafts of the two drive cylinders 21. Specifically, when the output of one drive cylinder 21 is too large, the synchronizing link 22 can transfer kinetic energy to the other drive cylinder 21, so that the two drive cylinders 21 drive the conductive mechanism 40 to rise and fall with the same output. The output of the two drive cylinders 21 can be synchronized through the synchronizing link 22, thereby ensuring the smooth rising and falling of the conductive mechanism 40.

[0053] In another specific embodiment, in addition to using a synchronizing link 22 for mechanical synchronization, an encoder (not shown) and a stroke detection device (not shown) can also be used. Specifically, the encoder is communicatively connected to the two drive cylinders 21, and the encoder is electrically connected to the stroke detection device. When one drive cylinder 21 outputs, the stroke detection device can obtain the output stroke of the drive cylinder 21, the encoder obtains this output stroke, and controls the other drive cylinder 21 to work with this output stroke. The encoder and stroke detection device can make the synchronization of the two drive cylinders 21 more precise, but the maintenance cost is higher.

[0054] In practical applications, it is often difficult for the electrode clamping mechanism 41 to precisely align with the conductive electrode of the graphitization furnace. Even if the electrode clamping mechanism 41 and the conductive electrode can be successfully aligned, the conductive electrode will undergo thermal expansion and contraction during power supply. To accommodate the thermal expansion and contraction of the conductive electrode, the electrode clamping mechanism 41 adopts an adaptive structure to adjust its position. However, the adaptive structure is complex and costly to use.

[0055] In this embodiment, the lifting mechanism 20 uses a chain 24 to suspend the conductive mechanism 40, thereby enabling the adaptive setting of the electrode clamping mechanism 41. That is, by utilizing the flexibility of the chain 24, the adaptive adjustment of the electrode clamping mechanism 41 can be achieved using only one component, greatly simplifying the structure of the electrode clamping mechanism 41 and reducing operating costs.

[0056] Of course, chain 24 can also be replaced by steel wire rope.

[0057] A pulley mounting bracket (not shown) is provided on the top frame 112, and a fixed pulley 23 is fixedly mounted on the pulley mounting bracket.

[0058] Please see Figure 3 and Figure 4 In one embodiment, the flexible connection assembly 30 includes: a shaft mounting base 31, a chain shaft 32, and chain connectors 33, wherein the chain shaft 32 passes through the shaft mounting base 31; the flexible connection assembly 30 includes two chain connectors 33, which are respectively disposed at both ends of the chain shaft 32.

[0059] One end of the output shaft of the drive cylinder 21 is provided with a collar (not shown in the figure), which is sleeved on the chain shaft 32 and located between the two side plates of the shaft mounting seat 31. The shaft mounting seat 31 can prevent the collar of the drive cylinder 21 from moving axially along the shaft of the drive cylinder 21, thereby improving the stability of the transmission of the flexible connection assembly 30.

[0060] Under the driving action of the drive cylinder 21, the output shaft of the drive cylinder 21 extends and shortens to drive the chain shaft 32 and chain connector 33 of the flexible connection assembly 30 to move, and then the chain connector 33 drives the chain 24 to move.

[0061] Furthermore, the chain connector 33 includes: a first connecting side plate 331, a second connecting side plate 332, and an intermediate connecting portion 333; the first connecting side plate 331 and the second connecting side plate 332 are arranged parallel to each other and spaced apart; the intermediate connecting portion 333 connects the first connecting side plate 331 and the second connecting side plate 332. One end of the first connecting side plate 331 and the second connecting side plate 332 has an opening, and the chain shaft 32 passes through the first connecting side plate 331 and the second connecting side plate 332.

[0062] In this embodiment, the chain connector 33 uses both a first connecting side plate 331 and a second connecting side plate 332, which can provide two support points for the chain shaft 32 inserted thereon, thereby improving the stability of the chain shaft 32 installation.

[0063] A chain mounting hole 334 is provided at one end of the first connecting side plate 331 and the second connecting side plate 332. The chain mounting hole 334 is used to provide a mounting position for the chain 24. One end of the chain 24 is provided with a plug (not shown) that is adapted to the chain mounting hole 334. By inserting the plug into the chain mounting hole 334 provided in the first connecting side plate 331 and the second connecting side plate 332, the chain 24 and the chain connector 33 are fixedly connected.

[0064] Of course, the chain 24 can also be installed in other ways, such as by buckle or pin, without being limited to the specific embodiment.

[0065] Please see Figure 5In one embodiment, the conductive mechanism 40 includes: a conductive frame 44, a column 43, an electrode clamping mechanism 41, and a busbar clamping mechanism 42. The column 43 is suspended and fixed on the conductive frame 44, and the electrode clamping mechanism 41 and the busbar clamping mechanism 42 are both disposed on the same column 43.

[0066] The conductive mechanism 40 includes three columns 43 spaced apart from each other, and three electrode clamping mechanisms 41 are distributed along the length of each column 43 to form a 3*3 square array to correspond to the distribution of conductive electrodes on the graphitization furnace. Each column 43 has a busbar clamping mechanism 42 at its lower end, which clamps the power supply busbar laid on the ground.

[0067] By setting the electrode clamping mechanism 41 and the busbar clamping mechanism 42 on the same column 43, the electrode clamping mechanism 41 and the busbar clamping mechanism 42 share the column 43, resulting in a simple and compact structure, easy assembly, and low operating cost.

[0068] Please see Figure 1 and Figure 6 In one embodiment, the trolley 100 further includes a translation mechanism 50, wherein the gantry 11 is movably mounted on the vehicle body 10 and configured to move back and forth under the drive of the translation mechanism 50.

[0069] Specifically, the power supply vehicle 100 has a power supply state and an idle state, and can switch between the two states. When switching to the power supply state, the translation mechanism 50 drives the gantry 11 to move forward, and the lifting mechanism 20 drives the conductive mechanism 40 to descend until the conductive mechanism 40 is connected to the conductive electrode of the graphitization furnace and the power supply busbar, respectively. When switching to the idle state, the translation mechanism 50 drives the gantry 11 to move backward, and the lifting mechanism 20 drives the conductive mechanism 40 to rise until the conductive mechanism 40 is separated from the conductive electrode of the graphitization furnace and the power supply busbar, respectively.

[0070] In this embodiment, the forward movement of the gantry 11 represents the trolley 100 moving closer to the graphitization furnace, while the backward movement of the gantry 11 represents the trolley 100 moving away from the conductive electrodes. In this embodiment, the power supply busbar is laid on the ground; the downward movement of the conductive mechanism 40 represents movement towards the power supply busbar, and the upward movement of the conductive mechanism 40 represents movement away from the power supply busbar. For example, when the power supply busbar is erected above the trolley 100, the upward movement of the conductive mechanism 40 represents movement towards the power supply busbar, and the downward movement of the conductive mechanism 40 represents movement away from the power supply busbar.

[0071] In summary, compared with the prior art, this utility model, by setting a lifting mechanism 20 on the trolley 100 and connecting the lifting mechanism 20 to the flexible connecting component 30, ensures accurate docking between the electrode clamping mechanism 41 and the conductive electrode when the lifting mechanism 20 pulls the electrode clamping mechanism 41 upward. If it is found that the electrode clamping mechanism 41 and the conductive electrode are not properly aligned, the flexible connecting component 30 causes the electrode clamping mechanism 41 to shake adaptively, thereby improving the stability of the trolley 100.

[0072] Obviously, the above embodiments are merely examples for the detailed description of this utility model, and are not intended to limit the implementation. This utility model can be implemented in many other ways different from those described herein. Although embodiments of this utility model have been described in conjunction with the accompanying drawings, those skilled in the art can make other modifications and variations based on the above description, and such modifications and variations still fall within the protection scope defined by the appended claims.
