Description

Technical Field

[0001] This utility model relates to the field of tooling equipment technology, specifically to a flexible telescopic unit module and a flexible platform. Background Technology

[0002] In the production or maintenance of some large vehicles or equipment, specialized production and maintenance tooling is required. This tooling is highly specialized and generally uses a fixed steel frame structure as the main body. The steel frame structure is basically compatible with the size of the vehicle or equipment to be maintained. When the model or specifications of the vehicle or equipment change, it cannot be reused and special tooling needs to be remade according to the requirements. This is not only time-consuming and labor-intensive, but also takes up a lot of space and is inconvenient to store. Existing flexible platforms are composed of multiple flexible telescopic unit modules. By operating each module, the telescopic distance can be adjusted according to actual operational needs, ensuring a suitable safety clearance between the extended end and the working surface for worker convenience. However, existing flexible telescopic unit modules cannot limit the extension distance of the slide rail, potentially leading to the slide rail detaching from the fixed rail. Furthermore, the lower and upper supports of the slide rail are connected by tenons and mortises. While the grooves in the lower supports are reinforced with longitudinal ribs to improve the slide rail's bending resistance, when the slide rail extends a considerable distance beyond the fixed rail and bears a large load in the vertical direction, the contact between the upper and lower supports, and between the longitudinal ribs and the upper and lower supports, is linear, resulting in significant localized pressure and a tendency to deform. Utility Model Content

[0003] To address the aforementioned technical problems, this utility model provides a flexible telescopic unit module and a flexible platform. The extension length of the sliding rail of the flexible telescopic unit module is limited by the cooperation of rigid stops and limiting components, preventing excessive extension. Furthermore, the lower support component is connected to the upper support component via a flanged connection. An inner support component within the lower support component cooperates with the upper support component, increasing the bearing area between them. This results in higher overall strength of the sliding rail, enabling it to withstand greater bending moments, ensuring support for workers, and improving safety performance.

[0004] This utility model provides a flexible telescopic unit module to solve the above-mentioned technical problems, including:

[0005] A fixed rail having a receiving cavity with an opening at at least one end;

[0006] A sliding rail is provided within the receiving cavity. The sliding rail includes a lower support member and an upper support member mounted on the upper side of the lower support member. The bottom of the lower support member is slidably engaged with the bottom wall of the receiving cavity along the axial direction of the sliding rail. A cavity is formed between the two side walls of the lower support member and the two side walls of the fixed rail, and the top of the two side walls extends outward to form a flange connected to the bottom wall of the upper support member. A limiting member is provided on at least one side wall of the lower support member. A rigid stop member connected to the fixed rail is provided in the cavity. The two sides of the upper support member have upwardly extending protrusions, which are slidably engaged with the two side walls of the fixed rail along the axial direction of the sliding rail.

[0007] The driving device includes a driving component connected to the fixed rail, and the output end of the driving component is connected to the sliding rail.

[0008] Furthermore, the fixed rail is provided with a mounting frame, and the mounting frame has mounting holes on both sides of the sliding rail along the axial direction. The driving component is fixed to the side wall of the mounting frame away from the sliding rail and its output end is connected to the mounting hole through a bearing. The sliding rail is provided with a mounting cavity for accommodating the lead screw. The lead screw is threadedly engaged with a threaded sleeve provided on the sliding rail and one end is connected to the output end of the driving component.

[0009] Furthermore, the mounting cavity is provided with two inner support members with inner cavities, one of which has a track in its inner cavity, and the lead screw is located in the track.

[0010] Furthermore, the bottom wall of the lower support member is provided with a connecting hole, and the bottom wall of the inner support member is provided with a strip-shaped hole extending along the width direction of the inner support member. A nut is provided in the connecting hole, and the small-diameter end of the nut extends into the strip-shaped hole.

[0011] Furthermore, at least one side wall of the fixed rail is provided with a first waist hole extending along the axial direction of the fixed rail; the side wall of the lower support member near the first waist hole is provided with a second waist hole at the same horizontal line as the first waist hole; the side wall of the inner support member near the second waist hole is provided with a third waist hole corresponding to the second waist hole; the top wall of the fixed rail is provided with a fourth waist hole; the upper support member is provided with a fifth waist hole at the same vertical line as the fourth waist hole; and the top wall of the inner support member on which the lead screw is provided is provided with a sixth waist hole corresponding to the fifth waist hole.

[0012] Furthermore, a touch sensor is provided on the extended end of the sliding rail.

[0013] Furthermore, the bottom wall of the fixed rail is provided with several keyholes.

[0014] Furthermore, the upper support member is provided with a first reinforcing member extending along the width direction of the upper support member and abutting the inner side of the protrusion at both ends, and a second reinforcing member extending along the axial direction of the upper support member, with one end of the second reinforcing member abutting the first reinforcing member and the other end abutting the end of the upper support member.

[0015] Furthermore, it also includes at least one set of outer support plates and inner support plates. The outer support plates are detachably connected to the top wall of the fixed rail via connectors, and the inner support plates are located inside the upper support member and are detachably connected to the upper support member via connectors.

[0016] This utility model also provides a flexible platform, including a support frame and at least two of the above-mentioned flexible telescopic unit modules, with two adjacent flexible telescopic unit modules arranged side by side, and the fixed rails of the flexible telescopic unit modules installed on the support frame.

[0017] The beneficial effects of this utility model are as follows: the sliding rail passes through the receiving cavity of the fixed rail, and the receiving cavity is used to constrain the movement trajectory of the sliding rail. Under the action of the driving device, the sliding rail extends or retracts from the fixed rail into the receiving cavity, realizing that the extended end of the sliding rail approaches or moves away from the working range. The bottom of the lower support member of the sliding rail slides in fit with the bottom wall of the receiving cavity, and there is a cavity between the two side walls of the lower support member and the two side walls of the fixed rail. The two sides of the upper support member have upwardly extending protrusions, which slide in fit with the two side walls of the fixed rail through the protrusions. At this time, the two side walls of the lower support member do not contact the fixed rail, and the top and bottom walls of the upper support member do not contact the fixed rail, which reduces the contact area between the sliding rail and the fixed rail, which is conducive to the sliding fit. When the sliding rail is subjected to pressure in the vertical direction and produces a small deformation, the cavity provides space for the deformation of the two side walls of the lower support member, so that it will not contact the fixed rail and thus get stuck. Furthermore, the tops of the two side walls of the lower support member extend outward to form flanges that connect with the bottom wall of the upper support member, increasing the contact area between the lower and upper support members. In this case, when the sliding rail is under pressure in the vertical direction, the pressure on the lower support member can be distributed and transmitted to the upper support member, increasing the strength of the sliding rail. The cooperation between the limiting member on the lower support member and the rigid stop member located in the cavity and on the fixed rail limits the outward extension distance of the sliding rail. When the sliding rail extends to its maximum extent, the limiting member abuts against the rigid stop member, preventing excessive outward extension of the sliding rail and ensuring a certain overlap length between the sliding rail and the fixed rail, thus ensuring the stable support of the sliding rail. In summary, by employing this utility model, the extension length of the sliding rail of the flexible telescopic unit module is limited through the cooperation of the rigid stop and the limiting component, thus preventing the sliding rail from extending excessively. Furthermore, the lower support component is connected to the upper support component through its flange, and the inner support component inside the lower support component cooperates with the upper support component, increasing the bearing area between them. This results in higher overall strength of the sliding rail, enabling it to withstand greater bending moments, ensuring support for workers, and improving safety performance.

Detailed Implementation

[0028] Referring to the accompanying drawings, the specific embodiments of this utility model will be described in detail.

[0029] Reference Figures 1 to 7 This utility model provides an embodiment of a flexible telescopic unit module.

[0030] A flexible telescopic unit module includes a fixed rail 100, a sliding rail 200, and a driving device 300. The fixed rail 100 has a receiving cavity 110 with at least one open end. The sliding rail 200 passes through the receiving cavity 110. The driving device 300 includes a driving member 310 connected to the fixed rail 100. The output end of the driving member 310 is connected to the sliding rail 200. The driving member 310 can be a hydraulic motor, a pneumatic motor, or an electric motor, as long as it allows the sliding rail 200 to slide within the fixed rail 100. Furthermore, a touch sensor 260 is provided on the extended end of the sliding rail 200. When the sliding rail 200 extends, if the contact probe of the touch sensor 260 comes into contact with an external obstacle, it compresses the metal spring inside the touch sensor 260, activating the circuit and transmitting a signal to the controller. The controller then controls the driving member 310 to stop, achieving the required extension length of the sliding rail 200.

[0031] Furthermore, the bottom wall of the fixed rail 100 is provided with several keyholes 140 for mounting the fixed rail 100 on the support frame 900. At this time, the sliding rail 200 passes through the receiving cavity 110 of the fixed rail 100. The receiving cavity 110 is used to constrain the movement trajectory of the sliding rail 200. Under the action of the driving device 300, the sliding rail 200 extends out of the fixed rail 100 or retracts into the receiving cavity 110, so that the extended end of the sliding rail 200 moves closer to or away from the working range.

[0032] In some embodiments, the sliding rail 200 includes a lower support member 210 and an upper support member 220 mounted on the upper side of the lower support member 210. The bottom of the lower support member 210 is slidably engaged with the bottom wall of the receiving cavity 110 along the axial direction of the sliding rail 200, and a cavity 230 is formed between the two side walls of the lower support member 210 and the two side walls of the fixed rail 100. The upper support member 220 has upwardly extending protrusions 221 on both sides, and a groove is formed between the two protrusions 221. The protrusions 221 are slidably engaged with the two side walls of the fixed rail 100 along the axial direction of the sliding rail 200. At this time, the two side walls of the lower support member 210 do not contact the fixed rail 100, and the top and bottom walls of the upper support member 220 do not contact the fixed rail 100. This reduces the contact area between the slide rail and the fixed rail 100, which is beneficial for sliding fit. When the slide rail 200 is subjected to pressure in the vertical direction and undergoes slight deformation, the cavity 230 provides space for the deformation of the two side walls of the lower support member 210, so that it will not contact the fixed rail 100 and thus will not cause jamming.

[0033] Furthermore, the upper support member 220 is provided with a first reinforcing member 223 extending along the width direction of the upper support member 220 and abutting both ends against the inner side of the protrusion 221, and a second reinforcing member 224 extending along the axial direction of the upper support member 220. One end of the second reinforcing member 224 abuts against the first reinforcing member 223, and the other end abuts against the end of the upper support member 220. Both the first reinforcing member 223 and the second reinforcing member 224 are located within the groove. At this time, when the sliding rail 200 extends outward by a large distance, the end of the inward extension of the sliding rail 200 abuts against the cavity wall of the receiving cavity 110, applying downward pressure to balance the bending moment on the sliding rail 200. At this time, the end of the inward extension of the upper support member 220 bears a large pressure. The strength of the inward extension of the upper support member 220 can be enhanced by the provision of the first reinforcing member 223 and the second reinforcing member 224.

[0034] The tops of the two side walls of the lower support member 210 extend outward to form flanges 211 that connect with the bottom wall of the upper support member 220, increasing the contact area between the lower support member 210 and the upper support member 220. In this case, when the sliding rail 200 is under pressure in the vertical direction, the pressure on the lower support member 210 can be distributed and transmitted to the upper support member 220, increasing the strength of the sliding rail. Furthermore, the flanges 211 have a first hole, and the bottom wall of the upper support member 220 has a second hole. A connecting nut 500 passes through the first and second holes to connect the upper support member 220 and the lower support member 210, facilitating individual replacement of either the upper support member 220 or the lower support member 210 and simplifying maintenance.

[0035] At least one side wall of the lower support member 210 is provided with a limiting member 212, and the cavity 230 is provided with a rigid stop member 231 connected to the fixed rail 100. Further, the rigid stop member 231 is located on the protruding end side of the sliding rail 200, while the limiting member 212 is located on the side of the support member near the driving member 310. Through the cooperation of the limiting member 212 and the rigid stop member 231, the outward extension distance of the sliding rail 200 can be limited. When the sliding rail 200 extends to its maximum extent, the limiting member 212 abuts against the rigid stop member 231, preventing the sliding rail 200 from extending excessively and ensuring a certain overlap length between the sliding rail 200 and the fixed rail 100, thus ensuring the stable support of the sliding rail 200.

[0036] In some embodiments, the drive component 310 is a motor, which can be a stepper motor or a servo motor. The extension length of the slide rail 200 is controlled by controlling the angular displacement of the stepper motor or servo motor. The fixed rail 100 is provided with a mounting frame 320. The mounting frame 320 has mounting holes 321 on both side walls along the axial direction of the slide rail 200. The drive component 310 is fixed to the side wall of the mounting frame 320 away from the slide rail 200, and its output end is connected to the mounting hole 321 through a bearing. The slide rail 200 is provided with a mounting cavity 250 for accommodating a lead screw 330. The lead screw 330 is threadedly engaged with a threaded sleeve 240 provided on the slide rail 200, and one end is connected to the output end of the drive component 310. The output end of the drive component 310 can be connected to the lead screw 330 through a flexible coupling or an elastic shaft to accommodate the swing of the slide rail 200. At this time, the mounting frame 320, which serves as the mounting base for the drive component 310, can withstand a larger load compared to the existing L-shaped mounting bracket. This prevents excessive torque from causing deformation or detachment of the mounting base when the drive component 310 drives the lead screw 330 to rotate. Simultaneously, the output end of the drive component 310 is connected to the mounting holes 321 on both sides of the mounting frame 320 via bearings. This allows for axial positioning of the lead screw 330 and enables it to bear the load during the sliding of the slide rail 200. This reduces the force exerted on the drive component 310 when it drives the slide rail 200 out of the receiving cavity 110 and bears the load, ensuring the stability of the slide rail 200 during movement and further reducing the possibility of the mounting frame 320 detaching from the fixed rail 100.

[0037] In some embodiments, the mounting cavity 250 is provided with two inner support members 400 each having an inner cavity 450. One of the inner support members 400 has a track 440 within its inner cavity 450, and the lead screw 330 is disposed within the track 440. The inner support member 400 not only divides the interior of the mounting cavity 250 into sections for easier arrangement of parts, but also improves the strength of the sliding rail 200, further ensuring support stability. The track 440 within the inner support member 400 supports and limits the lead screw 330, preventing it from swinging during rotation and causing damage.

[0038] Furthermore, the lower support member 210 has a connecting hole 213 on its bottom wall, and the inner support member 400 has a strip-shaped hole 410 extending along the width direction of the inner support member 400 on its bottom wall. A nut 500 is provided in the connecting hole 213, and the small-diameter end of the nut 500 extends into the strip-shaped hole 410. The nut 500 connects the inner support member 400 and the lower support member 210. The strip-shaped hole 410 on the inner support member facilitates the assembly of the inner support member 400 and the lower support member 210. If an error occurs during assembly, causing a deviation in the hole position, the nut 500 can be finely adjusted through the strip-shaped hole 410.

[0039] In some embodiments, to facilitate the inspection and maintenance of the flexible telescopic unit module, at least one side wall of the fixed rail 100 is provided with a first waist hole 120 extending along the axial direction of the fixed rail 100, and a second waist hole 214 at the same horizontal line as the first waist hole 120 is provided on the side wall of the lower support member 210 near the first waist hole 120, and a third waist hole 420 corresponding to the second waist hole 214 is provided on the side wall of the inner support member 400 near the second waist hole 214. In this case, the movement of the sliding rail 200 within the receiving cavity 110 can be observed through the first waist hole 120, while the condition of the track 440 can be observed through the second waist hole 214 and the third waist hole 420. Furthermore, the top wall of the fixed rail 100 is provided with a fourth waist hole 130, the upper support member 220 is provided with a fifth waist hole 222 perpendicular to the fourth waist hole 130, and the top wall of an inner support member 400 on which the lead screw 330 is located is provided with a sixth waist hole 430 corresponding to the fifth waist hole 222. At this time, the operating state of the internal lead screw 330 can be observed through the arrangement of the fourth waist hole 130, the fifth waist hole 222, and the sixth waist hole 430.

[0040] In some embodiments, the system further includes at least one set of outer support plates 600 and inner support plates 700. The outer support plates 600 are detachably connected to the top wall of the fixed rail 100 via connectors 800. Preferably, the size of the outer support plates 600 is adapted to the fixed rail 100, and multiple outer support plates 600 are spliced ​​and laid on the fixed rail 100. The inner support plates 700 are located within the upper support member 220 and are detachably connected to the upper support member 220 via connectors 800. The inner support plates 700 are disposed within the groove of the upper support member, and multiple inner support plates 700 are spliced ​​and laid within the upper support member 220. The top of the inner support plates 700 is flush with the upper edge of the protrusion 221 to ensure support effectiveness. In this case, the outer support plates 600 and inner support plates 700 can be assembled in multiple sets, which not only facilitates the maintenance of the flexible telescopic unit module but also adapts to the assembly of different sizes.

[0041] See Figure 8This utility model also provides a flexible platform, including a support frame 900 and at least two of the aforementioned flexible telescopic unit modules. Two adjacent flexible telescopic unit modules are arranged side-by-side, and the fixed rails 100 of the flexible telescopic unit modules are mounted on the support frame 900. The spacing between adjacent flexible telescopic unit modules is designed to prevent workers from stepping into gaps or tools from falling. This method allows for the assembly of work platforms of different sizes to be arbitrarily configured according to the work area, making assembly flexible and convenient. Furthermore, the extension distance of the sliding rail 200 of each flexible telescopic unit module can be individually adjusted, allowing for adaptive adjustments based on the actual work distance. It exhibits high overall strength, high load-bearing capacity, and high stability.
