All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0034] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0035] It should be noted that, where there is no conflict, the features in the embodiments of the present invention can be combined with each other.

[0036] The following describes in detail, with reference to the accompanying drawings, the specific structure of a machine maintenance ladder provided by an embodiment of the present invention and the corresponding technical effects it brings.

[0037] Please refer to Figure 1 The machine maintenance ladder 1 provided in this embodiment of the invention includes a frame 100, a reinforcement component, a step platform 300 and a ladder frame 400.

[0038] The frame 100 includes a first support frame 110, a second support frame 120, and a top frame 130. The first support frame 110 and the second support frame 120 are spaced apart along the x-direction on both sides of the top frame 130. That is, the top frame 130 is connected to the top of the first support frame 110 and the second support frame 120. The reinforcement component includes a reinforcement beam extending along the x-direction, and the two ends of the reinforcement beam are respectively connected to the first support frame 110 and the second support frame 120.

[0039] The reinforcing beam can move relative to the first support frame 110 and the second support frame 120 in the y direction and / or z direction, wherein the x direction, y direction and z direction are perpendicular to each other.

[0040] It should be noted that the verticality in this embodiment is not limited to being vertical in a strict sense; it is sufficient to mean approximately vertical.

[0041] Understandably, when the machine maintenance ladder 1 is moved to the outside of the process machine, the reinforcing beam can move in at least one of the y and / or z directions, which can change the shape and size of the space enclosed by the first support frame 110, the second support frame 120 and the reinforcing beam, thus adapting to different process machines and having good applicability.

[0042] Optionally, in some embodiments, the reinforcing beam may be movable only in the y-direction relative to the first support frame 110 and the second support frame 120. Alternatively, the reinforcing beam may be movable only in the z-direction relative to the first support frame 110 and the second support frame 120, or the reinforcing beam may be movable in both the y-direction and the z-direction relative to the first support frame 110 and the second support frame 120.

[0043] Optionally, to facilitate disassembly and assembly by operators, the two ends of the reinforcing beam are detachably connected to the first support frame 110 and the second support frame 120, respectively.

[0044] Understandably, the two ends of the reinforcing beam can be detachably connected to the first support frame 110 and the second support frame 120 respectively by threaded fasteners. Of course, the two ends of the reinforcing beam can also be snapped into the first support frame 110 and the second support frame 120 respectively.

[0045] In some alternative embodiments, the reinforcing beams are multiple and the multiple reinforcing beams are at least divided into groups. In some embodiments, the reinforcing beams are arranged in several groups and spaced apart along the z-direction, and the reinforcing beams in each group are spaced apart along the y-direction. That is, the multiple reinforcing beams are divided into multiple groups, the multiple groups of reinforcing beams are spaced apart along the z-direction, and the multiple reinforcing beams in each group are spaced apart along the y-direction.

[0046] For example, multiple reinforcing beams are divided into multiple groups of reinforcing beams, each group including two reinforcing beams spaced apart along the y-direction.

[0047] Of course, in some other embodiments, the number of reinforcing beams may also be one.

[0048] Optionally, in order to ensure the connection strength between the first support frame 110 and the second support frame 120, the reinforcement assembly also includes a fixing beam. The fixing beam extends along the x-direction, and both ends of the fixing beam are fixedly connected to the first support frame 110 and the second support frame 120, respectively. That is, the fixing beam cannot move relative to the first support frame 110 and the second support frame 120.

[0049] In this embodiment, the reinforcement component includes a first beam 210 and a second beam 220. It can be understood that in some embodiments, both the first beam 210 and the second beam 220 may be reinforcement beams, or in other embodiments, one of the first beam 210 and the second beam 220 may be a reinforcement beam and the other of the first beam 210 and the second beam 220 may be a fixing beam.

[0050] Optionally, the first beam 210 and the second beam 220 are spaced apart along the y-direction, and both the first beam 210 and the second beam 220 are reinforcing beams.

[0051] The first beam 210 can move in the y-direction relative to the first support frame 110 and the second support frame 120, and the second beam 220 can also move in the y-direction relative to the first support frame 110 and the second support frame 120.

[0052] Therefore, when the machine maintenance ladder 1 is moved to the outside of the process machine, the first beam 210 or the second beam 220 is opposite to the outside of the process machine. Since both the first beam 210 and the second beam 220 can move along the y-direction, that is, the first beam 210 and the second beam 220 can move away from or closer to the process machine in the y-direction. For example, when the first beam 210 is close to the process machine, the user can move the second beam 220 along the y-direction to the side furthest from the first beam 210 between the first support frame 110 and the second support frame 120. The user can also move the first beam 210 in the y-direction to adjust its depth in the y-direction to avoid process machines with different shapes and structures. This allows the system to adapt to process machines with different shapes and structures, and it has good applicability.

[0053] Please refer to Figures 2-3 For example, when the first beam 210 is close to the process machine, the user can move the second beam 220 along the y-direction of the first support frame 110 and the second support frame 120 to the side furthest from the first beam 210. At this time, the user can remove the first beam 210 from the first support frame 110 and the second support frame 120 so that there is the maximum fitting space between the first support frame 110, the second support frame 120 and the second beam 220. Of course, in order to ensure the stability of the frame 100, the user can adapt the first beam 210 to process machines of different shapes and sizes by moving it in the y-direction, so as to ensure that the machine maintenance ladder 1 can be as close as possible to the process machine.

[0054] Optionally, both ends of the first beam 210 can be connected to the first support frame 110 and the second support frame 120 by threaded fasteners, and both ends of the second beam 220 can also be connected to the first support frame 110 and the second support frame 120 by threaded fasteners. It is understood that by connecting the first support frame 110 and the second support frame 120 by threaded fasteners, the connection strength between the first beam 210 and the first support frame 110 and the second support frame 120 can be guaranteed, as can the connection strength between the second beam 220 and the first support frame 110 and the second support frame 120.

[0055] For example, the first support frame 110 can be provided with multiple first connecting parts arranged at intervals along the y direction, and the second support frame 120 can also be provided with multiple second connecting parts arranged at intervals along the y direction, corresponding one-to-one with the multiple first connecting parts. One end of the first beam 210 can be connected to the first connecting part by a threaded fastener, and the other end of the first beam 210 can be connected to the second connecting part by a threaded fastener. After the first beam 210 is unlocked from the first support frame 110 and the second support frame 120 by the threaded fastener, it can move in the y direction and connect with different first connecting parts or different second connecting parts to change the installation position of the first beam 210 in the y direction. The same applies to the second beam 220.

[0056] Optionally, the first support frame 110 may also be provided with multiple third connecting parts arranged at intervals along the z-direction, and the second support frame 120 may also be provided with multiple fourth connecting parts arranged at intervals along the z-direction corresponding to the multiple third connecting parts. One end of the first beam 210 can be connected to the third connecting part by a threaded fastener, and the other end of the first beam 210 can be connected to the fourth connecting part by a threaded fastener. Therefore, the position of the first beam 210 in the z-direction can be changed by connecting the first beam 210 to the third connecting parts and the fourth connecting parts at different heights.

[0057] Optionally, the first support frame 110 may also be provided with multiple fifth connecting parts spaced apart along the z-direction, and the fifth connecting parts and the third connecting parts spaced apart along the y-direction. The second support frame 120 may also be provided with multiple sixth connecting parts spaced apart along the z-direction, each corresponding to one of the multiple fifth connecting parts. One end of the second beam 220 can be connected to the fifth connecting part by a threaded fastener, and the other end of the second beam 220 can be connected to the sixth connecting part by a threaded fastener. Therefore, the second beam 220 can be connected to fifth connecting parts and sixth connecting parts of different heights to change the position of the second beam 220 in the z-direction.

[0058] Optionally, in some other embodiments, the first support frame 110 is equipped with a first track, and the second support frame 120 is equipped with a second track opposite to the first track. Both the first track and the second track extend along the y-direction. The two ends of the first beam 210 are connected to the first track and the second track, respectively. The two ends of the second beam 220 are connected to the first track and the second track, respectively. The first beam 210 can move on the first track and the second track and can be locked or unlocked relative to the first track and the second track. That is, when the first beam 210 is locked to the first track and the second track, the first beam 210 cannot move on the first track and the second track. Similarly, the second beam 220 can also be locked or unlocked on the first track and the second track. When the second beam 220 is locked to the first track and the second track, the second beam 220 cannot move on the first track and the second track.

[0059] Optionally, in some other embodiments, the first support frame 110 is equipped with a third track and a fifth track spaced apart along the y-direction, and the second support frame 120 is equipped with a fourth track and a sixth track spaced apart along the y-direction. The third track and the fourth track are arranged opposite each other, and the fifth track and the sixth track are arranged opposite each other. The third track, the fourth track, the fifth track and the sixth track all extend along the z-direction. The two ends of the first beam 210 are respectively connected to the third track and the fourth track and can move in the z-direction and can be locked or unlocked relative to the third track and the fourth track. The two ends of the second beam 220 are respectively connected to the fifth track and the sixth track and can move in the z-direction and can be locked or unlocked relative to the fifth track and the sixth track.

[0060] Of course, the first track is connected to the third and fifth tracks, the first beam 210 can move from the first track to the third track, the second beam 220 can move from the first track to the fifth track, the second track is connected to the fourth and sixth tracks, the first beam 210 can move from the second track to the fourth track, and the second beam 220 can move from the second track to the sixth track.

[0061] In this embodiment, the side of the first support frame 110 closest to the second support frame 120 is the mating side 112. The distance between the mating side 112 and the second support frame 120 in the x-direction gradually decreases in the direction close to the step 300. That is, the side of the first support frame 110 closest to the second support frame 120 is inclined. To facilitate the movement of the first beam 210 or the second beam 220 in the z-direction, the reinforcing beam is a telescopic reinforcing beam. Specifically, the reinforcing beam can extend and retract in the x-direction. In other words, both the first beam 210 and the second beam 220 can extend and retract in the x-direction. For example, the first beam 210... A beam 210 includes a split first sleeve and a first rod. The first rod is installed inside the first sleeve and can extend and retract relative to the extension direction of the first sleeve. One of the first sleeve and the first rod is connected to the first support frame 110, and the other of the first sleeve and the first rod is connected to the second support frame 120. A second beam 220 includes a second sleeve and a second rod. The second rod is installed inside the second sleeve and can extend and retract relative to the extension direction of the second sleeve. One of the second sleeve and the second rod is connected to the first support frame 110, and the other of the second sleeve and the second rod is connected to the second support frame 120. It should be noted that the aforementioned step 300 is installed on the top frame 130, and the ladder 400 is installed on the side of the first support frame 110 away from the second support frame 120.

[0062] Among them, the operators can climb up the ladder 400 to the platform 300 on the frame 100 and perform maintenance on the process machine at a certain height through the platform 300.

[0063] Of course, in some other embodiments, the mating side 112 of the first support frame 110 may also extend along the z direction, that is, the distance between the mounting side 111 of the first support frame 110 and the second support frame 120 remains unchanged in the direction close to the step 300.

[0064] To facilitate workers climbing the ladder 400, the side of the first support frame 110 away from the second support frame 120 is the mounting side 111 for installing the ladder 400. The distance between the mounting side 111 and the second support frame 120 in the x-direction gradually decreases in the direction close to the step 300. The extension direction of the ladder 400 is consistent with the extension direction of the mounting side 111, which avoids workers from climbing vertically.

[0065] To provide a more stable step area, the height distance between any two adjacent steps 410 can optionally be between 30 and 40 cm. For example, in this embodiment, the height distance between any two adjacent steps 410 can be 30 cm, 31 cm, 32 cm, 34 cm, 35 cm, 36 cm, 38 cm, or 40 cm. Of course, in some other embodiments, the height distance between two adjacent steps 410 can also be greater than 40 cm.

[0066] To further ensure the stability of the steps 410 of the ladder 400 for workers, the slope of any two adjacent steps 410 may optionally be between 3:1 and 4:1.

[0067] To prevent people from slipping when climbing the ladder, in some embodiments, the surface of the step 410 is provided with anti-slip components, which can be anti-slip coatings or anti-slip studs.

[0068] Optionally, to ensure the safety of workers climbing the ladder, the ladder frame 400 is equipped with protective handrails 420 on both sides in the y direction, and the step 410 is located between the two protective handrails 420.

[0069] Optionally, in some embodiments, to ensure the stability of the frame 100, the reinforcing components further include a third beam 230 and a fourth beam 240 extending along the x-direction. Both the third beam 230 and the fourth beam 240 are located above the first beam 210 and the second beam 220, and are spaced apart along the y-direction. The third beam 230 and the fourth beam 240 can both be the aforementioned reinforcing beams. Of course, in other embodiments, the third beam 230 and the fourth beam 240 can both be the aforementioned fixing beams. Alternatively, in other optional embodiments, one of the third beam 230 and the fourth beam 240 is a reinforcing beam, and the other is a fixing beam.

[0070] Optionally, in some embodiments, in order to further improve the adaptability of the frame 100 to more process equipment with different shapes and structures, the third beam 230 and the fourth beam 240 may not be fixed beams, but may be reinforcing beams. That is, the third beam 230 can move relative to the first support frame 110 and the second support frame 120 in the y direction and / or z direction, and the fourth beam 240 can move relative to the first support frame 110 and the second support frame 120 in the y direction and / or z direction.

[0071] Optionally, the third beam 230 and the fourth beam 240 can also be extended and retracted in the y direction to accommodate the different spacing dimensions of the first support frame 110 and the second support frame 120 in the y direction.

[0072] Optionally, the third beam 230 and the fourth beam 240 can also be fixed to the first support frame 110 and the second support frame 120 by threaded fasteners.

[0073] In detail, in this embodiment, the second support frame 120 includes a first support column 121, a second support column 122, and a first support beam 123. The first support column 121 and the second support column 122 are arranged at intervals along the y-direction. The first support beam 123 extends along the y-direction and its two ends are respectively connected to the first support column 121 and the second support column 122. The two ends of the first support column 121 are respectively connected to the first support beam 123 and the top frame 130. The two ends of the second support column 122 are respectively connected to the first support beam 123 and the top frame 130. To ensure the strength of the first support frame 110, the first support frame 110 also includes a second support beam 124 located between the top frame 130 and the first support beam 123. The two ends of the second support beam 124 are respectively connected to the first support column 121 and the second support column 122.

[0074] Optionally, the first beam 210 and the second beam 220 can move relative to the first support beam 123 in the y-direction. It is understood that the aforementioned second connecting part or second track can be installed on the first support beam 123. The aforementioned fourth track and sixth track can be installed on the first support column 121 and the second support column 122, respectively.

[0075] Optionally, in some embodiments, the machine maintenance ladder 1 further includes a lifting assembly installed between the top frame 130 and the platform 300. The lifting assembly is used to move the platform 300 up and down in the z-direction, so that operators can maintain components at different heights on the process machine. The lifting assembly can be a hydraulic lifting platform.

[0076] The platform 300 includes a work platform 310 and a safety fence 320 installed on the work platform 310. In this embodiment, the safety fence 320 has an entrance for workers to enter on the side near the ladder 400.

[0077] To protect the safety of workers, the length of the safety fence 320 in the z-direction is greater than or equal to 50 cm. In some embodiments, the protective handrail 420 on the ladder 400 is also connected to the safety fence 320.

[0078] Understandably, in order to avoid interference when the lifting assembly drives the platform 300 to move in the z direction, the protective handrail 420 may not be connected to the safety fence 320, and the protective handrail 420 may only be connected to the ladder frame 400.

[0079] To facilitate the movement of the machine maintenance ladder 1, the frame 100 in this embodiment is equipped with multiple wheels at the bottom. The wheels can be omnidirectional wheels and can be locked. That is to say, when the wheels are locked, they cannot rotate, thus preventing the machine maintenance ladder 1 from being moved easily. The wheels can only move after they are unlocked.

[0080] Optionally, a gravity sensor is installed on the side of the top frame 130 near the platform 300. That is, the gravity sensor is connected to the top frame 130 and the platform 300 on both sides in the z direction, so that the operator can detect the gravity on the platform 300.

[0081] In summary, the machine maintenance ladder 1 provided in this embodiment of the invention includes a frame 100 and a reinforcement assembly. The frame 100 includes a first support frame 110, a second support frame 120, and a top frame 130. The first support frame 110 and the second support frame 120 are spaced apart along the x-direction on both sides of the top frame 130. The reinforcement assembly includes a reinforcement beam extending along the x-direction, with both ends of the reinforcement beam connected to the first support frame 110 and the second support frame 120, respectively. The reinforcement beam can move relative to the first support frame 110 and the second support frame 120 in the y-direction and / or z-direction, and can be adapted to process machines with different shapes and structures by adjusting the reinforcement beam, thus having good applicability.

[0082] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention.
