Description

Technical Field

[0001] This utility model relates to the field of maintenance equipment technology, and in particular to a maintenance platform. Background Technology

[0002] Some maintenance platforms are equipped with laterally extendable pedal assemblies. These assemblies consist of multiple pedals that slide sequentially along a roughly horizontal direction. Adjusting the extension or retraction of the pedal assembly by sliding the pedals allows workers to perform operations from different positions, making the process more convenient and expanding the work area. In existing technologies, adjusting the extension or retraction of the pedal assembly requires sequentially sliding all the movable pedals, which is cumbersome, time-consuming, and labor-intensive. Utility Model Content

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a maintenance platform that, when the pedal assembly needs to be extended or retracted, enables all sliding pedals to slide synchronously, making operation simpler and more time- and labor-saving.

[0004] The maintenance platform according to an embodiment of the present utility model includes a support base and a pedal assembly. The pedal assembly includes multiple pedals, which are slidably connected in sequence along a first direction. One of the pedals is mounted on the support base. In any three adjacent pedals, the two side pedals are respectively provided with racks extending along the first direction and facing opposite directions. The middle pedal is provided with two transmission gears arranged along the first direction. The two transmission gears on the middle pedal mesh with the racks on the two side pedals, and a transmission chain is installed between the two transmission gears on the same pedal.

[0005] The repair platform according to the embodiments of this utility model has at least the following beneficial effects:

[0006] Taking a set of three adjacent pedals as an example, when one pedal is fixedly installed on the support, sliding the middle pedal will cause the transmission gear meshed with the rack on the fixed pedal to rotate. Since a transmission chain is installed between the two transmission gears on the same pedal, the other transmission gear will also rotate. Because the other transmission gear meshes with the rack on the other pedal, and the racks on the two pedals face opposite directions, the other pedal will slide relative to the middle pedal in the same direction. Similarly, through the cooperation of the racks and transmission gears on the other pedals, the remaining pedals can be driven to slide synchronously in the same direction, without having to slide all the slidable pedals in sequence. This makes the operation simpler and saves more time and effort.

[0007] According to some embodiments of the present invention, multiple pedals are nested together, and the outermost pedal is mounted on the support base.

[0008] According to some embodiments of the present invention, the maintenance platform further includes a drive assembly disposed on the outermost pedal to drive the pedal adjacent to the outermost pedal to slide along the first direction.

[0009] According to some embodiments of the present invention, the drive assembly includes a lead screw, a transmission nut, and a drive structure. The lead screw is rotatably mounted on the outermost pedal and extends along the first direction. The transmission nut is mounted on the pedal adjacent to the outermost pedal and is threadedly connected to the lead screw. The drive structure is mounted on the outermost pedal and is tractively connected to the lead screw to drive the lead screw to rotate.

[0010] According to some embodiments of the present invention, the driving structure includes a driving rod, a handle, a first bevel gear, and a second bevel gear. The driving rod is rotatably mounted on the outermost pedal and extends vertically. The handle is located at the top of the driving rod. The first bevel gear is coaxially mounted on the bottom of the driving rod, and the second bevel gear is coaxially mounted on the lead screw and meshes with the first bevel gear.

[0011] According to some embodiments of the present invention, in two adjacent pedals, one pedal is provided with a slider and the other pedal is provided with a guide rail, the guide rail extends along the first direction and is slidably connected to the slider.

[0012] According to some embodiments of the present invention, the transmission gear is coaxially connected to a transmission sprocket, and the transmission chain is installed between two corresponding transmission sprockets.

[0013] According to some embodiments of the present invention, the pedal assembly includes at least four pedals, and in three adjacent pedals, the rack and the transmission gear are respectively installed on opposite sides of the middle pedal.

[0014] According to some embodiments of the present invention, the maintenance platform further includes a guardrail, one end of which is connected to the outermost pedal and the other end of which is connected to the innermost pedal. The guardrail is adjustable in the first direction.

[0015] According to some embodiments of the present invention, at least two pedal assemblies are provided, and the at least two pedal assemblies are arranged side by side along a second direction, the second direction being perpendicular to the first direction.

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.

Therefore, they should not be construed as limitations on this utility model.

[0050] In the description of this utility model, "multiple" refers to two or more. The use of "first" and "second" is for distinguishing technical features only and should not be construed as indicating or implying relative importance, or implicitly indicating the number of technical features or their sequential relationship.

[0051] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0052] The following is for reference. Figures 1 to 10 A repair platform according to an embodiment of the present utility model is described.

[0053] like Figures 1 to 10 As shown, the maintenance platform according to an embodiment of the present invention includes a support base 100 and a pedal assembly 200.

[0054] The bottom end of the support base 100 can be supported on the ground by a mounting bracket, and the support base 100 is used to support the pedal assembly 200.

[0055] The pedal assembly 200 can be one or more, and includes multiple pedals 201. Specifically, it includes at least three pedals 201, for example, it can include four pedals 201. The multiple pedals 201 are slidably connected sequentially along a first direction, for example, the first direction can be horizontal or slightly inclined relative to the horizontal direction. One pedal 201 is mounted on the support base 100, for example, the outermost pedal 201 can be mounted on the support base 100. Of course, other pedals 201 can also be mounted on the support base 100, for example, the middle pedal 201 can be mounted on the support base 100. In this case, the pedal assembly 200 can be extended and retracted from the middle along both ends, which will not be described in detail here.

[0056] In any three adjacent pedals 201, the two pedals 201 on both sides are provided with racks 202 extending along the first direction and facing opposite directions, and the middle pedal 201 is provided with two transmission gears 203 arranged along the first direction. The two transmission gears 203 on the middle pedal 201 mesh with the racks 202 on the two pedals 201 on both sides, and a transmission chain 204 is installed between the two transmission gears 203 on the same pedal 201. In this way, the two transmission gears 203 on the same pedal 201 can rotate synchronously.

[0057] Specifically, such as Figure 2 , Figure 3 , Figures 5 to 8As shown, when there are four pedals 201, the four pedals 201 along the first direction can be sequentially defined as the first pedal 2011, the second pedal 2012, the third pedal 2013, and the fourth pedal 2014. The first pedal 2011 can be mounted on the support base 100. The first pedal 2011 is provided with a rack 202 and can be defined as the first rack 2021. The second pedal 2012 is slidably connected to the first pedal 2011. The second pedal 2012 is provided with two transmission gears 203 and can be defined as the first transmission gears 2031. The second pedal 2012 is provided with a rack 202 and can be defined as the second rack 2022. A transmission chain 204 is installed between the two first transmission gears 2031 and can be defined as the first transmission chain 2041. The third... The pedal 2013 is slidably connected to the second pedal 2012. The third pedal 2013 is provided with two transmission gears 203, which can be defined as the second transmission gears 2032. The third pedal 2013 is provided with a rack 202, which can be defined as the third rack 2023. A transmission chain 204, which can be defined as the second transmission chain 2042, is installed between the two second transmission gears 2032. The fourth pedal 2014 is slidably connected to the third pedal 2013. The fourth pedal 2014 is provided with a rack 202, which can be defined as the fourth rack 2024. The two first transmission gears 2031 respectively mesh with the first rack 2021 and the third rack 2023, and the two second transmission gears 2032 respectively mesh with the second rack 2022 and the fourth rack 2024.

[0058] In this invention, taking a set of three adjacent pedals 201 as an example, when one pedal 201 is fixedly installed on the support base 100, the middle pedal 201 is slid, and the transmission gear 203 meshed with the rack 202 on the fixed pedal 201 will rotate. Since a transmission chain 204 is installed between the two transmission gears 203 on the same pedal 201, the other transmission gear 203 will also rotate. Since the other transmission gear meshes with the rack 202 on the other pedal 201, and the racks 202 on the two pedals 201 face opposite directions, the other pedal 201 will slide relative to the middle pedal 201 in the same direction. Similarly, through the mutual cooperation of the racks 202 and transmission gears 203 on the other pedals 201, the remaining pedals 201 can be driven to slide synchronously in the same direction, without having to slide all the slidable pedals 201 in sequence. This makes the operation simpler and saves more time and effort.

[0059] It should be noted that in any three adjacent pedals 201, the racks 202 on the two outer pedals 201 face opposite directions. This means that the sides of the two racks 202 with meshing teeth face opposite directions. This ensures that all pedals 201 slide synchronously in the same direction, thereby allowing the pedal assembly 200 to unfold or retract. When there are three pedals 201, the middle pedal 201 only has a transmission gear 203 installed and does not need a rack 202. When there are at least four pedals 201, the middle pedal 201 has both a transmission gear 203 and a rack 202 installed.

[0060] In some embodiments of this utility model, such as Figure 2 and Figure 3 As shown, multiple pedals 201 are nested together, with the outermost pedal 201 mounted on the support base 100. Adjacent pedals 201 are nested together and can slide relative to each other through the nesting, resulting in a simple structure. Furthermore, the outermost pedal 201 being mounted on the support base 100 avoids interference with the sliding of other pedals 201.

[0061] It should be noted that in other embodiments of this utility model, the multiple pedals 201 can also be connected in other ways and do not necessarily need to be nested together. For example, when the multiple pedals 201 slide to make the pedal assembly 200 in a retracted state, the multiple pedals 201 can be stacked.

[0062] In some embodiments of this utility model, such as Figures 1 to 5 as well as Figure 9 As shown, the maintenance platform also includes a drive assembly 300, which is located on the outermost pedal 201 to drive the pedals 201 adjacent to the outermost pedal 201 to slide along a first direction. By operating the drive assembly 300, the drive assembly 300 can drive the pedals 201 adjacent to the outermost pedal 201 to slide along the first direction, thereby enabling the other pedals 201 to slide synchronously, making the operation simpler and more convenient.

[0063] It should be noted that in some other embodiments of this utility model, the corresponding pedal 201 can also be pushed directly by a person.

[0064] In some embodiments of this utility model, such as Figures 1 to 5 as well as Figure 9 As shown, the drive assembly 300 includes a lead screw 301, a transmission nut 302, and a drive structure. The lead screw 301 is rotatably mounted on the outermost pedal 201 and extends along a first direction. The transmission nut 302 is mounted on the pedal 201 adjacent to the outermost pedal 201 and is threadedly connected to the lead screw 301. The drive structure is mounted on the outermost pedal 201 and is drively connected to the lead screw 301 to drive the lead screw 301 to rotate.

[0065] The operator operates the drive mechanism, which controls the lead screw 301 to rotate. The lead screw 301 then drives the transmission nut 302 to move along the first direction. The transmission nut 302, in turn, causes the pedals 201 adjacent to the outermost pedal 201 to slide relative to the outermost pedal 201 along the first direction, thereby enabling the other pedals 201 to slide synchronously. This makes the operation simpler and more convenient. Moreover, through the cooperation of the lead screw 301 and the transmission nut 302, the pedals 201 can slide a longer distance with more precise sliding direction, resulting in better practicality.

[0066] It should be noted that the drive component 300 can also be other structures, for example, it can be a drive cylinder directly.

[0067] In some embodiments of this utility model, such as Figures 1 to 5 as well as Figure 9 As shown, the drive structure includes a drive rod 303, a handle 304, a first bevel gear 305, and a second bevel gear 306. The drive rod 303 is rotatably mounted on the outermost pedal 201 and extends vertically. The handle 304 is located at the top of the drive rod 303. The first bevel gear 305 is coaxially mounted on the bottom of the drive rod 303. The second bevel gear 306 is coaxially mounted on the lead screw 301 and meshes with the first bevel gear 305. When the operator rotates the handle 304, the handle 304 drives the drive rod 303. The drive rod 303, through the meshing of the first bevel gear 305 and the second bevel gear 306, drives the lead screw 301 to rotate.

[0068] In this embodiment, since the drive rod 303 extends vertically and the handle 304 is located at the top of the drive rod 303, it is more convenient for the operator to operate.

[0069] It should be noted that the drive structure can also be other structures, such as a drive motor, which controls the rotation of the lead screw 301, resulting in a high degree of automation.

[0070] In some embodiments of this utility model, such as Figures 4 to 9 As shown, in two adjacent pedals 201, one pedal 201 is provided with a slider 205, and the other pedal 201 is provided with a guide rail 206. The guide rail 206 extends along a first direction and is slidably connected to the slider 205. For example, in two adjacent pedals 201, one pedal 201 may have sliders 205 on both sides, with the sliders 205 having grooves, and the other pedal 201 may have guide rails 206 on both sides, with the guide rails 206 slidably installed in the grooves. In this embodiment, the cooperation between the slider 205 and the guide rail 206 makes the sliding of the pedal 201 more precise and smooth.

[0071] It is understandable that the pedal 201 in the middle position is not only equipped with a slider 205, but also with a guide rail 206, so as to facilitate sliding connection with the pedals 201 on both sides.

[0072] In some embodiments of this utility model, such as Figure 7 As shown, a transmission gear 203 is coaxially connected to a transmission sprocket 207, and a transmission chain 204 is installed between the two corresponding transmission sprockets 207. In this embodiment, a transmission sprocket 207 is coaxially arranged at one end of the transmission gear 203. When one of the two corresponding transmission gears 203 rotates, it can drive the coaxial transmission sprocket 207 to rotate synchronously. The two transmission sprockets 207 can rotate synchronously through the transmission action of the transmission chain 204, and the other transmission sprocket 207 can drive the other transmission gear 203 to rotate synchronously. In this embodiment, the transmission gear 203 is coaxially connected to the transmission sprocket 207, which not only facilitates the synchronous rotation of the two corresponding transmission gears 203, but also avoids interference with the meshing between the transmission gear 203 and the rack 202.

[0073] In some embodiments of this utility model, such as Figure 4 , Figure 6 and Figure 7 As shown, the pedal assembly 200 includes at least four pedals 201. Among three adjacent pedals 201, a rack 202 and a transmission gear 203 are respectively installed on opposite sides of the middle pedal 201. When the pedal assembly 200 includes at least four pedals 201, the middle pedal 201 not only has two transmission gears 203 installed, but also requires a rack 202. In this embodiment, the rack 202 and transmission gear 203 are located on opposite sides of the middle pedal 201, which not only makes installation more convenient but also avoids interference. Furthermore, it makes the force on the pedal 201 more even, thus making the pedal 201 slide more smoothly.

[0074] It should be noted that in some other embodiments of this utility model, the pedal assembly 200 may also include only three pedals 201.

[0075] In some embodiments of this utility model, such as Figure 1 and Figure 10As shown, the maintenance platform also includes a guardrail 400. One end of the guardrail 400 is connected to the outermost pedal 201, and the other end is connected to the innermost pedal 201. The guardrail 400 can be extended and retracted along a first direction. For example, the guardrail 400 may include two first rails 401 and two second rails 402. The two first rails 401 are respectively installed on the outermost pedal 201 and the innermost pedal 201, and the two second rails 402 are respectively located on opposite sides of the pedal assembly 200. The two ends of the second rails 402 are respectively connected to the two first rails 401. The first rails 401 can be configured as an openable and closable structure to facilitate the entry and exit of personnel. The second rails 402 can be configured as a telescopic structure, for example, it may include multiple guardrail units that are slidably connected in sequence, or it may be configured as a telescopic scissor-type structure, thus facilitating extension and retraction along with the pedal assembly 200. In this embodiment, the guardrail 400 provides better safety, and the guardrail 400 can be extended and retracted along with the pedal assembly 200 along the first direction, avoiding interference and improving practicality.

[0076] In some embodiments of this utility model, such as Figure 10 As shown, at least two pedal assemblies 200 are provided, and the at least two pedal assemblies 200 are arranged side by side along a second direction, which is perpendicular to the first direction. In this embodiment, providing at least two pedal assemblies 200 can increase the working range of the operator, and at least two pedal assemblies 200 can be extended and retracted independently. Therefore, when the operator needs to move to the required position, the corresponding pedal assembly 200 can be extended, making the operation simple and convenient.

[0077] It should be noted that in some other embodiments of this utility model, the pedal assembly 200 may also be a single unit.

[0078] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
