Description

Technical Field

[0001] This utility model relates to the field of electrical equipment technology, and more specifically, to a transfer vehicle and a switch cabinet. Background Technology

[0002] In electrical equipment, the relocation of equipment is often involved, such as electrical cabinets. In particular, circuit breakers in switch cabinets generally need to be relocated. Specifically, a transport vehicle moves the circuit breaker to one side of the switch cabinet and then pushes it into the mounting cavity located in the cabinet.

[0003] However, the existing transfer vehicle is not equipped with a structure for locking and positioning with the cabinet. As a result, when the circuit breaker is moved from the transfer vehicle into the installation cavity, the transfer vehicle is prone to displacement or swaying, which may lead to risks such as collision between the circuit breaker and the cabinet. Utility Model Content

[0004] This utility model addresses the shortcomings of existing methods by proposing a transfer vehicle and switch cabinet to solve the technical problem that the transfer vehicle can be moved when the circuit breaker is not fully installed in the cabinet, which poses a safety risk.

[0005] In the first aspect, this utility model embodiment provides a transfer vehicle, including: a vehicle body and a positioning component;

[0006] The positioning component includes a top rod disposed at one end of the vehicle body. The top rod includes a connecting section and a sealing block. The sealing block is disposed at the end of the connecting section opposite to the vehicle body.

[0007] Wherein, along the axial direction of the connecting segment, the projected portion of the end cap is located outside the projection of the connecting segment to be configured to form a connection with an external component.

[0008] Optionally, the top rod further includes a support section, and the connecting section is connected to the vehicle body through the support section. Along the axial direction of the connecting section, the projection of the support section covers the projection of the connecting section and is partially located outside the projection of the connecting section.

[0009] Optionally, the top rod is a round rod, and the diameter of the end cap is larger than the diameter of the connecting section.

[0010] Optionally, the top rod is a round rod; wherein the diameters of the end cap and the support section are both greater than the diameter of the connecting section, and the diameter of the support section is greater than or equal to the diameter of the end cap.

[0011] Optionally, it also includes a mounting base, which includes a locking plate, an extension plate, and a fixing plate, wherein the locking plate is provided with locking holes;

[0012] The card hole is provided through the support section, and the extension plate is provided on at least one side of the card plate. The fixing plate is provided at the end of the extension plate opposite to the card plate for fixing to the vehicle body.

[0013] Optionally, the number of the positioning elements is at least one.

[0014] Optionally, the top of the vehicle body is provided with a guide rail for importing or exporting the parts to be transferred;

[0015] The guide rail extends along the length of the vehicle body.

[0016] Optionally, the number of guide rails is two, and the two guide rails are arranged opposite to each other on the top sides of the vehicle body.

[0017] Secondly, this utility model embodiment provides a switch cabinet, including a cabinet body, a door, a circuit breaker, and a transfer vehicle as described above;

[0018] The cabinet is provided with a mounting cavity for installing the circuit breaker, and one end of the mounting cavity serves as an opening for the circuit breaker to enter and exit.

[0019] The valve is movably disposed at the opening in a vertical direction to open and close the opening. The valve is provided with a connecting groove for limiting the relative movement of the connecting section. The bottom end of the connecting groove is provided with a first inlet and outlet hole for the connecting section and the end cap block to pass through, and the top end is provided with a second inlet and outlet hole for the connecting section and the end cap block to pass through. A positioning hole for the insertion of the top rod is provided at the opening and outside the valve.

[0020] When the valve is closed, the first inlet / outlet hole is aligned with the positioning hole. The sealing block of the top rod at one end of the vehicle body can pass through the positioning hole and the first inlet / outlet hole in sequence until the connecting section is located in the first inlet / outlet hole. When the valve descends, the connecting section generates relative displacement in the connecting groove. The connecting groove restricts the sealing block from going back to prevent the vehicle body from detaching away from the cabinet. When the valve is open, the sealing block is aligned with the second inlet / outlet hole to release the restriction with the connecting groove.

[0021] Optionally, it also includes a locking element, which includes a blocking block and a reset element disposed on the cabinet and acting on the blocking block, wherein the width of the blocking block is greater than the width of the connecting groove;

[0022] The blockage is inserted into the first inlet / outlet when the valve is closed.

[0023] The beneficial technical effects brought about by the technical solution provided by this utility model embodiment include:

[0024] The locking mechanism between the end cap of the top rod and the cabinet door prevents the transfer trolley from detaching from the cabinet during door opening, thus preventing movement. Additionally, the top rod inserts into the positioning hole, and this connection guides the transfer trolley to the cabinet, ensuring alignment between the circuit breaker and the installation cavity during installation and preventing the transfer trolley from swinging and colliding with the opening edge. In summary, the top rod, with its simple structure, achieves both anti-movement and improved alignment, avoiding collisions during installation.

[0042] The present invention provides a transfer vehicle and a switch cabinet, which are intended to solve the above-mentioned technical problems.

[0043] The technical solution of this utility model and how the technical solution of this utility model solves the above-mentioned technical problems will be described in detail below with specific embodiments.

[0044] This utility model embodiment provides a transfer vehicle product, the structural schematic diagram of which is shown below. Figures 1 to 4 As shown, it includes: a vehicle body 10 and a positioning member 20; the positioning member 20 includes a top rod 21 disposed at one end of the vehicle body 10, the top rod 21 includes a connecting section 211 and a sealing block 212, the sealing block 212 is disposed at the end of the connecting section 211 away from the vehicle body 10; wherein, along the axial direction of the connecting section 211, the projected portion of the sealing block 212 is located outside the projection of the connecting section 211 to be configured to form a connection with an external component.

[0045] In this embodiment, the end cap 212 can be understood as protruding from the end edge of the connecting segment 211, thereby the end cap 212 is used to achieve hook positioning and prevent the vehicle body 10 from moving.

[0046] Optionally, the top rod 21 also includes a support section 213, and the connecting section 211 is connected to the vehicle body 10 through the support section 213. Along the axial direction of the connecting section 211, the projection of the support section 213 covers the projection of the connecting section 211 and is partially located outside the projection of the connecting section 211.

[0047] In this embodiment, it can be understood that the cross-section of the support segment 213 is larger than the cross-section of the connecting segment 211. Therefore, it can be known that the outer diameter of the support segment 213 is larger than the outer diameter of the connecting segment 211.

[0048] Optionally, the top rod 21 is a round rod, and the diameter of the end cap 212 is larger than the diameter of the connecting section 211.

[0049] As described above, the cross-section of the top rod 21 can be selected as a polygon or other unspecified shape. In this embodiment, the top rod 21 is preferably a round rod. Preferably, the end cap 212 and the connecting section 211 are coaxially arranged. The round rod structure can effectively prevent corner collisions.

[0050] Optionally, the diameters of both the end capping block 212 and the support section 213 are larger than the diameter of the connecting section 211, and the diameter of the support section 213 is greater than or equal to the diameter of the end capping block 212.

[0051] Preferably, the connecting segment 211, the end cap 212, and the support segment 213 are coaxially arranged. The portion of the end cap 212 protruding from the connecting segment 211 along the axial direction is used for hooking and positioning, while the large-diameter structure of the support segment 213 is designed to increase the connection surface with the vehicle body 10 as mentioned above, thereby enhancing the stability of the connection.

[0052] For example, the diameter of the support section 213 is larger than the diameter of the end cap 212. Alternatively, if the support section 213 needs to have a larger contact surface with the vehicle body 10, the support section 213 can be selected to have a larger diameter, which will not be elaborated here.

[0053] Optionally, it also includes a mounting base 40, which includes a clamping plate 41, an extension plate 42 and a fixing plate 43, wherein the clamping plate 41 is provided with a clamping hole 4101;

[0054] The card hole 4101 is fitted onto the support section 213, and an extension plate 42 is provided on at least one side of the card plate 41. A fixing plate 43 is provided on the end of the extension plate 42 away from the card plate 41 for fixing to the vehicle body 10.

[0055] Preferably, the clamping plate 41, the extension plate 42, and the fixing plate 43 form a Z-shaped structure, so that the fixing plate 43 can be connected or directly welded to the vehicle body 10. As mentioned above, the clamping plate 41 provides support at one end of the push rod 21 (i.e., the support section 213) to prevent the push rod 21 from swaying and deflecting when impacted.

[0056] The extension plate 42 and the fixing plate 43 form an L-shaped structure, and the clamping plate 41 may have only one side with the extension plate 42 and the fixing plate 43. More preferably, both sides of the clamping plate 41 may have an L-shaped extension plate 42 and a fixing plate 43, thereby forming a balanced fixation on both sides of the clamping plate 41.

[0057] In conjunction with the embodiment where the top rod 21 is a round rod, this embodiment should be understood as follows: the end block 212, the connecting section 211 and the support section 213 are coaxially arranged, and the locking hole 4101 is a round hole that allows the support section 213 to pass through.

[0058] Furthermore, the support section 213 has a plug-in section 214 at one end opposite to the connecting section 211. The cross-section of the plug-in section 214 is smaller than that of the support section 213, and the plug-in section 214 is preferably provided with threads. When the top rod 21 is installed on the vehicle body 10, a plug-in plate is provided on the vehicle body 10. The plug-in plate has a plug-in hole through which the plug-in section 214 can pass. The plug-in section 214 passes through the plug-in hole. One end of the support section 213 abuts against one side of the plug-in plate, and a nut is provided on the other side of the plug-in plate. The nut is installed on the thread of the plug-in section 214 to bolt and lock the plug-in section 214 to the plug-in plate.

[0059] Optionally, the number of positioning elements 20 is at least one.

[0060] For example, a positioning member 20 is provided on one side of one end of the vehicle body 10, and a straight rod structure for inserting a positioning rod is provided on the other side. In other embodiments, positioning members 20 may be provided on both sides of one end of the vehicle body 10.

[0061] Preferably, the positioning element 20 is positioned near the top of the vehicle body 10. This top-position position allows the positioning element 20 to be closer to the product being transported above the vehicle body. When the positioning element 20 is inserted into the cabinet 60 to complete the positioning and then the product is moved, the vibration and swaying caused by the product movement can be effectively controlled by the nearby positioning element 20, thus effectively avoiding the movement problem of the vehicle body 10 and simultaneously fulfilling the positioning and guiding functions.

[0062] Optionally, the top of the vehicle body 10 is provided with a guide rail 50 for importing or exporting the parts to be transferred; the guide rail 50 is arranged along the length of the vehicle body.

[0063] In this embodiment, the guide rail 50 is used to better install and remove the circuit breaker 90.

[0064] Optionally, there are two guide rails 50, which are arranged opposite to each other on the top sides of the vehicle body 10.

[0065] Specifically, there are two guide rails 50, which form a double-sided guide, resulting in better stability.

[0066] Furthermore, the guide rail 50 has an L-shaped structure, and two L-shaped guide rails 50 are arranged facing each other to form a two-sided encircling pattern.

[0067] Furthermore, to facilitate leveling and height adjustment of the guide rail 50, a lifting device 30 is provided at the bottom of the guide rail 50. For example, the lifting device 30 may be a hydraulic or electric telescopic cylinder, a hydraulic or electric telescopic cylinder lifting platform, or a bolted connection structure. Both ends of the bottom of each guide rail 50 are respectively provided with the lifting device 30, thereby achieving leveling or lifting of the guide rail 50.

[0068] In addition, the bottom of the vehicle body 10 is generally equipped with rollers to facilitate the movement of the vehicle body 10.

[0069] Based on the same inventive concept, see [reference] Figures 5 to 9This utility model embodiment provides a switch cabinet, including a cabinet body 60, a door 70, a circuit breaker 90, and a transfer vehicle as described above; the cabinet body 60 is provided with a mounting cavity 601 for installing the circuit breaker 90, and one end of the mounting cavity 601 serves as an opening 6011 for the circuit breaker 90 to enter and exit; the door 70 is movably disposed at the opening 6011 in a vertical direction to realize the opening and closing of the opening 6011, and the door 70 is provided with a connecting groove 701 for restricting the relative movement of the connecting section 211, the bottom end of the connecting groove 701 is provided with a first inlet and outlet hole 702 for the connecting section 211 and the end cap 212 to pass through, and the top end is provided with a second inlet and outlet hole 703 for the connecting section 211 and the end cap 212 to pass through, at the opening 6011. A positioning hole 6021 for inserting the top rod 21 is provided at position 011 and outside the valve. When the valve 70 is closed, the first inlet / outlet hole 702 is aligned with the positioning hole 6021. The end cap 212 of the top rod 21 at one end of the vehicle body 10 can pass through the positioning hole 6021 and the first inlet / outlet hole 702 in sequence until the connecting section 211 is located in the first inlet / outlet hole 702. When the valve 70 descends, the connecting section 211 generates relative displacement in the connecting groove 701. The connecting groove 701 restricts the end cap 212 from going back to prevent the vehicle body 10 from detaching away from the cabinet 60. When the valve 70 is open, the end cap 212 is aligned with the second inlet / outlet hole 703, releasing the restriction of the connecting groove 701 that prevents it from going back.

[0070] It is understood that the switch cabinet is used in conjunction with the aforementioned transfer vehicle. Taking the vehicle body 10 with a positioning element 20 as an example, in this embodiment, in the direction of movement of the door 70, the two sides of the door 70 of the cabinet body 60 are respectively provided with a connecting groove 701, a first inlet / outlet hole 702, and a second inlet / outlet hole 703. In this embodiment, the up-and-down movement of the door 70 corresponds to the closing and opening of the opening 6011. Additionally, for example, a guide sleeve 602 is provided at the opening 6011, and in the depth direction of the mounting cavity 601, a positioning hole 6021 is arranged on the central axis of the guide sleeve 602. In this embodiment, the top rod 21 is exemplified as a round rod, which includes a connecting section 211, a sealing block 212, a support section 213, and a plug-in section 214, and the diameter of the plug-in section 214 is larger than the diameter of the sealing block 212.

[0071] In the initial state, the valve 70 closes the opening 6011 (i.e., the closed state), and the circuit breaker 90 is not installed in the mounting cavity 601 at this time. The connecting groove 701, the first inlet / outlet hole 702, and the guide sleeve 602 are all located in the area of ​​the opening 6011. At this time, the circuit breaker 90 is placed on the guide rail 50. With the end of the vehicle body 10 equipped with the positioning member 20 as the front end, the vehicle body 10 is pushed forward towards the opening. The sealing block 212 of the front end of the push rod 21 passes through the positioning hole 6021 and the first inlet / outlet hole 702 in sequence. At this time, the support section 213 is inserted into the positioning hole 6021 to achieve positioning and guidance. The connecting section 211 is located in the connecting groove 701. The operating valve 70 is lowered, and the connecting groove 701 and the first inlet / outlet hole 702 follow. The connecting section 211 enters the connecting groove 701 from the first inlet / outlet hole 702. At this time, the projection part of the sealing block 212 in the axial direction of the connecting section 211 is outside the width area of ​​the connecting groove 701. Therefore, the sealing block 212 cannot pass back into the connecting groove 701. At this time, the vehicle body 10 cannot be retracted. Therefore, when the valve 70 is opened (not to the fully open position), the sealing block 212 is hooked and positioned with the valve 70 to restrict the retraction of the vehicle body 10. When the valve 70 is fully opened (at this time, the end block 212 is aligned with the second inlet / outlet hole 703), the circuit breaker 90 can be pushed from the guide rail 50 into the installation cavity. After the circuit breaker 90 is installed, the vehicle body 10 is pulled back and the push rod 21 is removed from the second inlet / outlet hole 703.

[0072] To facilitate understanding of the lifting and lowering of the valve 70, the following are examples of possible solutions for opening and closing the valve 70: Guide rods are provided on both sides of the valve 70. A guide block with a guide hole corresponding to each guide rod is provided in the cabinet 60. One guide rod passes through the guide hole of one guide block. A linear drive device (such as a linear motor) is provided in the cabinet 60. The linear drive device is located below the opening, and its drive end is connected to the lower end of the valve 70. When the linear drive device extends, it drives the valve 70 to rise and close; when it retracts, it drives the valve 70 to fall and open. The guide rods follow the lifting and lowering of the valve 70 and always move within the guide holes, thus guiding the lifting and lowering of the valve 70. Therefore, the opening and closing of the valve 70 can be accomplished by controlling the linear drive device.

[0073] An extended revolving door is typically installed at the opening 6011, located outside the valve 70. The revolving door can be closed at any time after the circuit breaker 90 enters the cabinet.

[0074] In summary, the positioning component 20 is directly connected to the valve 70 to achieve the positioning of the vehicle body 10, and the opening movement of the valve 70 itself completes the limiting between the valve 70 and the top rod 21. No additional locking device is needed for the top rod 21, greatly simplifying the structure of the entire switchgear. Furthermore, the connection position between the top rod 21 and the valve 70 is fixed, ensuring that the circuit breaker 90 is directly aligned with the opening 6011. This allows the circuit breaker 90 to smoothly enter the mounting cavity 601 through the opening 6011, preventing collisions between the circuit breaker 90 and the cabinet body 60.

[0075] In addition, to enable the circuit breaker 90 to detach from the guide rail 50, a roller is provided at the bottom of the circuit breaker 90. The roller enables the circuit breaker 90 to be smoothly and effortlessly pushed from the guide rail 50 into the mounting cavity 601.

[0076] Similarly, to facilitate the entry of the circuit breaker 90 into the mounting cavity 601, tracks are provided on both sides of the mounting cavity 601 in the depth direction. The rollers of the circuit breaker 90 can roll on the tracks to enable the circuit breaker 90 to enter the mounting cavity quickly and conveniently.

[0077] In addition, one end of the transfer car on the positioning hole 6021 is set as a flared mouth to facilitate the insertion of the top rod 21.

[0078] Optionally, it also includes a locking element 80, which includes a blocking block 81 and a reset element 82 disposed on the cabinet 60 and acting on the blocking block 81. The width of the blocking block 81 is greater than the width of the connecting groove 701. The blocking block 81 is sealed in the first inlet / outlet hole 702 when the door 70 is in the closed state.

[0079] For example, the blocking block 81 is adapted to the first inlet / outlet hole 702, so the blocking block 81 cannot enter the connecting groove 701. The blocking block 81 is movably mounted on the cabinet 60. The reset member 82 is driven by a spring, which is a compression spring. It is mounted on the cabinet 60 and its compression state changes as the blocking block 81 moves. When the valve 70 is closed, the blocking block 81 is located in the first inlet / outlet hole 702, preventing the valve 70 from descending, thus achieving self-locking of the valve 70. Therefore, if the circuit breaker 90 needs to be installed at this time, the blocking block 81 needs to be pushed out of the first inlet / outlet hole 702 by the sealing block 212 of the push rod 21 at the front end of the vehicle body 10. At the same time, the connecting section 211 enters the first inlet / outlet hole 702. When the valve 70 moves downward, the connecting section 211 enters the connecting groove 701, so that the valve can reach the open state and push the circuit breaker 90 into the cabinet 60. Conversely, the circuit breaker 90 is removed from the cabinet 60, and the valve 70 moves upward to the closed state. After the vehicle body 10 is removed, the end block 212 exits the first inlet / outlet hole 702, and the locking block 81 of the latch 80 is re-locked back into the first inlet / outlet hole 702.

[0080] For example, see Figure 10 The compression springs in the aforementioned reset component 82 are arranged side by side on one side of the block 81. The compression springs are sleeved on a fixed round rod. The block 81 is welded to a movable curved plate and moves synchronously with the movable curved plate. When the block 81 is pushed out of the first inlet / outlet hole 702 or the second inlet / outlet hole 703 by the push rod 21, the compression springs in the reset component 82 are compressed and stored by the movable curved plate. When the push rod 21 is removed, the movable curved plate is no longer subjected to the continuous force of the push rod 21. At this time, the compression springs release energy to reset the movable curved plate, and the block 81, which moves synchronously with it, is reset and snapped into the first inlet / outlet hole 702 or the second inlet / outlet hole 703.
