Description

Technical Field

[0001] This utility model relates to the field of power equipment technology, and in particular to a liftable support base and an adaptive external guide rail. Background Technology

[0002] In the electrical field, power equipment such as switchgear often requires external guide rails to transport large devices such as floor-mounted trolleys during operation. However, traditional external guide rails have certain limitations in practical applications.

[0003] On the one hand, many traditional external guide rails have a fixed height, making it difficult to adjust flexibly according to different working environments and usage requirements. On some electrical production lines, different production processes have different requirements for equipment height, and fixed-height external guide rails cannot adapt to various production scenarios, which greatly limits their versatility and practicality, resulting in low work efficiency.

[0004] On the other hand, some external guide rails have a less compact structural design and a more complex installation process, which not only increases installation costs and time but also makes effective arrangement difficult within limited operating space. Furthermore, due to the instability of the support structure, vibrations and swaying are prone to occur during equipment operation, affecting the smooth operation of the equipment and thus reducing the performance of the entire external guide rail system.

[0005] In addition, existing height-adjustable support devices are often complex in structure, costly, and not easy to operate. They are also difficult to adjust freely in a limited operating space, which is not conducive to practical application. Utility Model Content

[0006] The purpose of this invention is to provide a height-adjustable support base and an adaptive external guide rail to improve the flexibility of height adjustment, ease of operation and support stability, optimize the specific structure and reduce production costs.

[0007] To achieve this objective, the present invention adopts the following technical solution:

[0008] A height-adjustable support base includes a support chassis, a guide rod, and a positioning bolt. The support chassis has a through hole. The bottom end of the guide rod is movably engaged with the top end of the support chassis, and the guide rod can move up and down relative to the support chassis. The guide rod has a mating groove, and the top of the groove wall has a mating surface. Along the direction from the opening of the groove to the bottom of the groove, the mating surface gradually inclines towards the axis of the groove. The positioning bolt includes a contact section and a connecting section coaxially connected. The connecting section passes through the through hole and partially extends into the mating groove. The connecting section is selectively connected to the support chassis. The outer diameter of the contact section gradually decreases in the direction away from the connecting section. The side wall of the contact section forms a pressing surface, which abuts against the mating surface to support the guide rod.

[0009] As an optional technical solution for the liftable support base, the bottom end of the guide rod is provided with a guide post, the top end of the support chassis is provided with a receiving groove, the guide post is at least partially matched and inserted into the receiving groove, and the through hole is connected to the side wall of the receiving groove.

[0010] As an optional technical solution for the liftable support base, the side wall of the receiving groove is provided with at least one limiting strip groove, the limiting strip groove extends in the vertical direction, and the side wall of the guide column is provided with protrusions, the number of protrusions is the same as the number of limiting strip grooves, and each protrusion is slidably engaged with one of the limiting strip grooves.

[0011] As an optional technical solution for the liftable support base, the side wall of the receiving groove is also provided with an installation strip groove. The number of protrusions and the number of limiting strip grooves are the same. One end of each installation strip groove is connected to the bottom end of a limiting strip groove, and the other end is connected to the opening of the receiving groove. Each protrusion is slidably engaged with one installation strip groove.

[0012] As an optional technical solution for the liftable support base, the mounting strip groove includes a vertical strip groove and an arc-shaped strip groove connected end to end. The arc-shaped strip groove is arranged along the side wall of the receiving groove. One end of the arc-shaped strip groove is connected to the bottom end of the limiting strip groove, and the other end is connected to the bottom end of the vertical strip groove. The vertical strip groove extends in the vertical direction, and the top end of the vertical strip groove is connected to the opening of the receiving groove.

[0013] As an optional technical solution for the liftable support base, the axis of the mating groove is parallel to the axis of the positioning bolt, and both are parallel to the horizontal plane.

[0014] As an optional technical solution for the liftable support base, the contact surface between the pressing surface and the mating surface is a fan-shaped curved surface.

[0015] As an optional technical solution for the liftable support base, the wall of the through hole is provided with internal threads, and the outer wall of the connecting section is provided with external threads that match the internal threads.

[0016] An adaptive external guide rail includes a support platform, a slide rail, and at least two of the above-mentioned liftable support seats. The slide rail is located at the top of the support platform, and the top of the guide rod is fixed to the bottom of the support platform.

[0017] As an optional technical solution for adaptive external guide rails, the edge of the support platform is provided with at least one connector, which can be detachably connected to an external device.

[0018] The beneficial effects of this utility model are:

[0019] This height-adjustable support base utilizes a guide rod that can move up and down relative to the support chassis to achieve its lifting function. This allows the height of the support base to be adjusted according to actual needs, improving its applicability and flexibility, and adapting to working scenarios with different height requirements. The pressing surface of the positioning bolt abuts against the mating surface of the guide rod's groove, providing stable support for the guide rod and effectively fixing it at a specific height position. This ensures stable support at different heights, enhancing the versatility and reliability of the support base during operation and preventing the guide rod from swaying during support. The above design features simple components, low cost, and good safety, with the advantages of easy operation and easy adjustment within confined operating spaces.

[0020] This adaptive external guide rail uses a height-adjustable support base, allowing the height of the support platform to be adjusted according to actual needs. This enables the guide rail to adapt to different working environments and usage requirements, thus ensuring the versatility and practicality of the adaptive external guide rail and improving its working efficiency. The adaptive external guide rail integrates the height-adjustable support base, support platform, and guide rail into a complete external guide rail system, featuring a compact structure that is easy to install and use. The height-adjustable support base provides stable support to the support platform, thereby ensuring the stability of the guide rail. This allows equipment running on the guide rail to move smoothly, reducing the impact of vibration and swaying on equipment operation and improving the overall performance of the adaptive external guide rail.

[0030] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0031] like Figures 1 to 3 As shown, this embodiment provides a liftable support base 3, including a support base 5, a guide rod 4, and a positioning bolt 6; the support base 5 has a through hole 7; the bottom end of the guide rod 4 is movably engaged with the top end of the support base 5, and the guide rod 4 can move up and down relative to the support base 5; the guide rod 4 has a mating groove, and the top of the groove wall has a mating surface 13; along the direction from the opening of the groove to the bottom of the groove, the mating surface 13 gradually inclines towards the axis of the groove; the positioning bolt 6 includes a contact section and a connecting section coaxially connected; the connecting section passes through the through hole 7 and partially extends into the mating groove; the connecting section is selectively connected to the support base 5; the outer diameter of the contact section gradually decreases in the direction away from the connecting section; the side wall of the contact section forms a pressing surface 8; the pressing surface 8 is used to abut against the mating surface 13 to support the guide rod 4.

[0032] The liftable support base 3 utilizes the guide rod 4, which can move up and down relative to the support chassis 5, to achieve its lifting function. This allows the height of the liftable support base 3 to be adjusted according to actual needs, improving its applicability and flexibility, and enabling it to adapt to working scenarios with different height requirements. The pressing surface 8 of the positioning bolt 6 abuts against the mating surface 13 of the guide rod 4's groove, providing stable support for the guide rod 4 and effectively fixing it at a specific height position. This ensures that the liftable support base 3 can provide stable support at different heights, improving its versatility and reliability during operation and preventing the guide rod 4 from swaying during support. The above design features simple components, low cost, and good safety, with the advantages of easy operation and easy free adjustment within limited operating spaces.

[0033] In this embodiment, the bottom end of the guide rod 4 is provided with a guide post, the top end of the support base 5 is provided with a receiving groove, the guide post is at least partially matched and inserted into the receiving groove, and the through hole 7 is connected to the side wall of the receiving groove. The through hole 7 is located on the side wall of the receiving groove.

[0034] The guide post at the bottom of the guide rod 4 is fitted into the receiving groove of the supporting chassis 5, providing precise guidance for the up and down movement of the guide rod 4, making the lifting and lowering process of the guide rod 4 more stable and smooth, and reducing the possibility of deviation and shaking.

[0035] The through hole 7 is connected to the side wall of the receiving groove, facilitating the placement bolt 6 to pass through the through hole 7 and extend into the mating groove. This reduces the difficulty of installing and adjusting the placement bolt 6, thereby enabling the support and positioning of the guide rod 4. The above structural improvements optimize the connection methods at various points of the liftable support base 3, making the overall structural layout of the liftable support base 3 more compact and reasonable.

[0036] Furthermore, the sidewall of the receiving groove is provided with at least one limiting strip groove 11, which extends vertically. The sidewall of the guide post is provided with protrusions 9, the number of which is the same as the number of limiting strip grooves 11, and each protrusion 9 is slidably engaged with one limiting strip groove 11. Specifically, there are two limiting strip grooves 11, which are symmetrically arranged about the axis of the receiving groove.

[0037] The limiting groove 11 on the side wall of the receiving groove slides into the protrusion 9 on the side wall of the guide column, which restricts the rotation and lateral movement of the guide rod 4 during the lifting process, ensuring that the guide rod 4 can only move up and down in the vertical direction, further improving the stability and guiding accuracy of the liftable support 3.

[0038] Furthermore, the side wall of the receiving groove is also provided with mounting slots, the number of protrusions 9 and limiting slots 11 are the same, and one end of each mounting slot is connected to the bottom end of a limiting slot 11, and the other end is connected to the opening of the receiving groove, and each protrusion 9 is slidably engaged with a mounting slot.

[0039] The installation of the strip groove allows the guide column to smoothly enter the receiving groove through the installation strip groove and finally cooperate with the limiting strip groove 11, which reduces the difficulty of disassembling and assembling the guide rod 4 and the support chassis 5, simplifies the disassembly and assembly process of the liftable support 3, and improves the assembly and maintenance efficiency of the liftable support 3.

[0040] Furthermore, the installation groove includes a vertical groove 10 and an arc-shaped groove 12 connected end to end. The arc-shaped groove 12 is arranged along the side wall of the receiving groove. One end of the arc-shaped groove 12 is connected to the bottom end of the limiting groove 11, and the other end is connected to the bottom end of the vertical groove 10. The vertical groove 10 extends in the vertical direction, and the top end of the vertical groove 10 is connected to the opening of the receiving groove.

[0041] The mounting slots, including vertical slots 10 and arc-shaped slots 12, provide a more reasonable path selection for the installation of the guide post. The design of the arc-shaped slot 12 clearly guides the movement path of the protrusion 9, allowing the guide post to rotate at a certain angle during installation. This helps the protrusion 9 accurately enter the limiting slot 11, further improving the installation efficiency of the liftable support 3 and optimizing the disassembly and assembly process. These improvements make the installation process of the guide post smoother and also prevent the guide rod 4 from accidentally coming off after installation to a certain extent.

[0042] In one embodiment of this invention, the central angle of the arc-shaped groove 12 is 45°. In other embodiments of this invention, all the arc-shaped grooves 12 are connected end to end to form an annular groove. The specific structure of the arc-shaped groove 12 is common knowledge in the art and is determined by those skilled in the art based on engineering practice. This is not an important aspect to be protected by this utility model and will not be described in detail here.

[0043] During assembly, the protrusion 9 of the guide rod 4 is pushed into the bottom along the vertical strip groove 10 inside the support base 5, and then inserted into the limiting strip groove 11 by rotation. Finally, the positioning bolt 6 is screwed into the mating groove inside the guide rod 4 through the through hole 7 on the support base 5.

[0044] In this embodiment, the axis of the mating groove is parallel to the axis of the positioning bolt 6, and both are parallel to the horizontal plane.

[0045] The fact that the axis of the mating groove is parallel to the axis of the positioning bolt 6 and parallel to the horizontal plane ensures that when the positioning bolt 6 presses against the guide rod 4, the supporting force of the positioning bolt 6 on the guide rod 4 is transmitted more evenly and stably, which improves the load-bearing capacity and support efficiency of the liftable support seat 3, avoids the loss of force transmission and structural instability caused by the non-parallel axis, and can more effectively realize the support and fixation of the guide rod 4 by the positioning bolt 6.

[0046] For example, the contact surface between the pressing surface 8 and the mating surface 13 is a fan-shaped curved surface.

[0047] The contact surface between the pressure surface 8 and the mating surface 13 is a fan-shaped curved surface, which increases the contact area between the two, makes the support force distribution more uniform, reduces the pressure per unit area, reduces local stress concentration, reduces the probability of wear, extends the service life of the liftable support 3, and also improves the stability of the support.

[0048] In this embodiment, the wall of the through hole 7 is provided with internal threads, and the outer wall of the connecting section is provided with external threads that match the internal threads.

[0049] The internal thread on the wall of the through hole 7 matches the external thread on the outer wall of the connecting section, allowing the positioning bolt 6 to move back and forth by rotation. This facilitates adjustment of the support height and support force of the guide rod 4, achieving a reliable connection between the positioning bolt 6 and the support base 5. By rotating the positioning bolt 6, the length of the positioning bolt 6 extending into the mating groove can be precisely adjusted, thereby achieving fine-tuning of the height of the guide rod 4 and improving the accuracy of height adjustment of the liftable support base 3. Simultaneously, the threaded connection provides good fixation, reliably securing the position of the guide rod 4.

[0050] In this embodiment, a rubber pad 14 is provided at the bottom of the support chassis 5. The bottom surface of the rubber pad 14 is provided with anti-slip texture. The liftable support 3 is in contact with the ground through the rubber pad 14.

[0051] like Figures 1 to 4 As shown, this embodiment also provides an adaptive external guide rail, including a support platform 1, a slide rail 2, and at least two of the above-mentioned liftable support seats 3. The slide rail 2 is located at the top of the support platform 1, and the top of the guide rod 4 is fixed to the bottom of the support platform 1.

[0052] This adaptive external guide rail uses a height-adjustable support base 3, which allows the height of the support platform 1 to be adjusted according to actual needs, enabling the slide rail 2 to adapt to different working environments and usage requirements. This ensures the versatility and practicality of the adaptive external guide rail and improves its working efficiency. The adaptive external guide rail integrates the height-adjustable support base 3 with the support platform 1 and the slide rail 2 to form a complete external guide rail with a compact structure that is easy to install and use. The height-adjustable support base 3 provides stable support for the support platform 1, thereby ensuring the stability of the slide rail 2. This allows equipment running on the slide rail 2 to move smoothly, reducing the impact of vibration and swaying on equipment operation and improving the overall performance of the adaptive external guide rail.

[0053] In this embodiment, the edge of the support platform 1 is provided with at least one connector 15, which is detachably connected to an external device. Specifically, the connector 15 is a hook, and there are two hooks for hooking the external device.

[0054] The connector 15 at the edge of the support platform 1 can be detachably connected to external devices, which facilitates the connection and combination of the adaptive external guide rail with different external devices, enhances the scalability and applicability of the adaptive external guide rail, and makes it easy to install and use in different devices, thereby meeting different application requirements.

[0055] In this embodiment, there are two parallel slide rails 2, located at the two ends of the top of the support platform 1, and two liftable support seats 3 are respectively located directly below the two slide rails 2 to further ensure the uniform distribution of the support force; the top of the guide rod 4 is welded to the bottom of the support platform 1.

[0056] In this embodiment, the external device is a switch cabinet, and the slide rail 2 is used to transport the floor-mounted handcart.

[0057] In the existing technology, external guide rails for floor-mounted trolleys are widely used in the power industry to move the floor-mounted trolley out of or into the circuit breaker room of the switchgear, so as to complete the purpose of maintenance or replacement of the floor-mounted trolley.

[0058] However, construction sites often have uneven ground or height differences, making it difficult to ensure proper contact between the traditional external guide rail and the ground after connection. This results in poor support from the external guide rail, causing the floor-mounted trolley to wobble when pulled out or pushed in, which can easily lead to equipment damage and pose certain safety hazards.

[0059] When the ground at the construction site is uneven or has height differences, the adjustable support seat 3 adapts to the ground to achieve the purpose of support, while the slide rail 2 can support the floor-mounted handcart to be pushed in and pulled out smoothly, so as to realize the replacement operation of the floor-mounted handcart.

[0060] Before adjusting the height-adjustable support base 3, the operator needs to unscrew the positioning bolts 6 a certain distance and align the two connecting pieces 15 with the holes on the switchgear, thus positioning the adaptive outer guide rail with the guide rail inside the switchgear. At this time, the support base 5 automatically conforms to the ground under gravity. Then, rotate the positioning bolts 6 on the support base 5 to ensure a tight fit between the pressure surface 8 and the mating surface 13. Finally, move the floor-mounted trolley along the slide rail 2 on the adaptive outer guide rail from one end of the support platform 1 to the other. Due to the reliable operation of the height-adjustable support base 3, the support platform 1 remains in contact with the ground, providing good support, ensuring the operator's safety, and preventing equipment damage.

[0061] The above process first determines the height by having the support chassis 5 contact the ground, and then uses the positioning bolts 6 to fix the support chassis 5 and the guide rod 4. This operation allows the adaptive outer guide rail to adaptively conform to the ground, which is simple to operate and provides good support. It helps to solve the problem of the adaptive outer guide rail not conforming to the ground when the ground is uneven or there are height differences, and reduces the safety hazards during the pushing of the handcart.

[0062] It effectively solves the problem that the support platform 1 of the adaptive external guide rail cannot fit the ground due to uneven ground at the construction site, ensuring the support effect, preventing the handcart from being unstable when pushed in or pulled out, ensuring the personal safety of operators, and preventing equipment damage.

[0063] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here.
