[0045] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0046] Please also read Figures 1 to 3The auxiliary walking platform on the overhead travelling vehicle provided by the present invention is now described. The auxiliary walking platform on the overhead travelling vehicle comprises a fixed plate 10, a cover plate 11, a first rotating shaft 20, a transition plate 30, a second rotating shaft 40, a follower plate 50 and a foot pedal 51. The fixed plate 10 is arranged up and down and is used to be fixed to the overhead travelling vehicle. The fixed plate 10 is used to be arranged on one side of the reducer on the overhead travelling vehicle; the cover plate 11 is fixedly arranged on the fixed plate 10, the cover plate 11 is arranged horizontally and is used to cover the top of the reducer on the overhead travelling vehicle; the first rotating shaft 20 is arranged on the top of the fixed plate 10, and the axial direction of the first rotating shaft 20 is parallel to the axial direction of the fixed plate 10. The first side of the transition plate 30 is rotatably connected to the fixed plate 10 through the first rotating shaft 20; the second rotating shaft 40 is arranged on the second side of the transition plate 30, and the second side is the opposite side of the first side; one side of the follower plate 50 is rotatably connected to the transition plate 30 through the second rotating shaft 40, and the opposite side of the rotating side of the follower plate 50 is used to support the ground, and the plate surface of the follower plate 50 is parallel to the plate surface of the fixed plate 10; the foot pedal 51 is fixedly arranged on the follower plate 50, and the plate surface of the foot pedal 51 is parallel to the plate surface of the cover plate 11;

[0047] In the initial state, the fixed plate 10, the transition plate 30 and the follower plate 50 are sequentially connected along the first preset direction and enclosed to form a storage space for accommodating the reducer, and the transition plate 30 and the foot pedal 51 are both located in the storage space;

[0048] In the working state, the first rotating shaft 20 and the second rotating shaft 40 rotate 180 degrees respectively, and the foot pedal 51, the follower plate 50, the transition plate 30, the fixed plate 10 and the cover plate 11 are sequentially connected along the first preset direction to form a walking platform.

[0049] It should be noted that Figure 1 and Figure 3 The dotted rectangle in the middle indicates the location of the reducer.

[0050] The auxiliary walking platform on the overhead travelling crane provided in this embodiment is shown in FIG. Figure 1 In the intuitive direction, in the initial state, the transition plate 30 is located on the right side of the fixed plate 10, and the follower plate 50 is located on the right side of the transition plate 30. At this time, the transition plate 30 is located on the top of the cover plate 11, and the foot pedal 51 is located in the storage space; when a person needs to enter the overhead crane from the top, the follower plate 50 is pulled, and the follower plate 50 drives the transition plate 30 to rotate, and the first rotating shaft 20 and the second rotating shaft 40 are both rotated 180 degrees, see Figure 3 At this time, the transition plate 30 is located on the left side of the fixed plate 10, and the follower plate 50 is located on the left side of the transition plate 30, that is, the transition plate 30 and the follower plate 50 are both turned over 180 degrees, so that when a person enters the overhead travelling crane from the top, he can enter the overhead travelling crane by stepping on the cover plate 11, the transition plate 30 and the foot pedal 51 in sequence; after entering the overhead travelling crane, in order to save space and facilitate operation, the person turns the first rotating shaft 20 and the second rotating shaft 40 over 180 degrees to restore the initial state.

[0051] Compared with the prior art, the auxiliary walking platform on the overhead crane of the present invention can be used as a cover shell covering the outer periphery of the reducer on the overhead crane when not in use, thereby protecting the reducer and not occupying space at other positions on the overhead crane, which is convenient for personnel to work in the overhead crane; when in use, the cover plate 11, the transition plate 30 and the foot pedal 51 can be deformed and flipped to form an auxiliary platform, the height of the cover plate 11 is lower than the height of the transition plate 30, and the height of the foot pedal 51 is lower than the height of the cover plate 11 and the transition plate 30, respectively, thereby improving the safety of use and making the entry process of personnel more convenient.

[0052] In some embodiments, an improved implementation of the first rotating shaft 20 and the second rotating shaft 40 can be as follows: Figure 1 to Figure 2 See the structure shown. Figure 1 to Figure 2 , the first rotating shaft 20 is rotatably connected to the fixed plate 10 and fixed to the first side of the transition plate 30; the second rotating shaft 40 is rotatably connected to the transition plate 30 and fixed to the follower plate 50; both ends of the first rotating shaft 20 and the second rotating shaft 40 are respectively provided with self-locking components 60, and the self-locking components 60 include a positioning portion fixed to the first rotating shaft 20 or the second rotating shaft 40, and a locking portion 62 fixed to the fixed plate 10 or the transition plate 30, the positioning portion has the freedom to slide back and forth along the radial direction of the first rotating shaft 20 or the second rotating shaft 40, and the outer circumference of the locking portion 62 is recessed to form a positioning groove that cooperates with the positioning portion. That is, a positioning portion is respectively provided at both ends of the first rotating shaft 20, and the corresponding fixing plate 10 is provided with a locking portion 62 corresponding to the positioning portion on the first rotating shaft 20; a positioning portion is respectively provided at both ends of the second rotating shaft 40, and the corresponding transition plate 30 is provided with a locking portion 62 corresponding to the positioning portion on the second rotating shaft 40. When the first rotating shaft 20 and the second rotating shaft 40 need to be rotated and adjusted, the positioning portion and the positioning groove on the locking portion 62 are spaced apart, that is, the positioning portion does not enter the positioning groove. At this time, the positioning portion rotates with the rotation of the first rotating shaft 20 or the second rotating shaft 40; when the first rotating shaft 20 and the second rotating shaft 40 have completed their rotation, the positioning portion can be slid so that the positioning portion is close to the positioning groove, and then the positioning portion is engaged with the positioning groove to achieve the fixation of the first rotating shaft 20 and the second rotating shaft 40. At this time, the states of the transition plate 30 and the follower plate 50 are locked, and a specific state can be maintained to ensure stability when used as a walking platform and to ensure the personal safety of personnel.

[0053] In some embodiments, an improved implementation of the self-locking assembly 60 can be implemented as follows: Figure 1 to Figure 2 See the structure shown. Figure 1 to Figure 2The self-locking assembly 60 also includes a fixed disk 61 and a clamping block 63. The fixed disk 61 includes two fixed sheets 611 arranged at intervals along the axial direction of the first rotating shaft 20 or the second rotating shaft 40. The fixed disk 61 is arranged at the end of the first rotating shaft 20 or the second rotating shaft 40; the clamping block 63 is clamped between the two fixed sheets 611, and the clamping block 63 has the freedom to slide along the radial direction of the fixed disk 61. A protrusion 61 parallel to the radial direction of the fixed disk 61 is extended from the clamping block 63. The protrusion 61 is located on one side of the outside of the fixed disk 61 and forms a positioning portion. Optionally, the fixed disk 61 can be sleeved on the first rotating shaft 20 or the second rotating shaft 40, and then the fixed disk 61 and the first rotating shaft 20 or the second rotating shaft 40 are fixed by key matching or the like, and then the clamping block 63 is assembled between the two fixed sheets 611. This structure allows the self-locking assembly 60 to be disassembled into multiple parts, which are then conveniently transported to the upper vehicle. The structure is simple, easy to assemble, reduces the labor intensity of installation on the overhead crane, and is flexible to use.

[0054] It should be noted that in order to achieve the clamping of the clamping block 63 between the two fixing plates 611, it can also slide radially along the fixing disk 61. The clamping degree of the clamping block 63 is relatively weak, so that the clamping block 63 can slide radially along the fixing disk 61 by pulling strongly, thereby driving the protrusion 61 in and out of the positioning groove.

[0055] In some embodiments, an improved implementation of the above-mentioned follower plate 50 can be adopted as follows Figure 1 and Figure 3 See the structure shown. Figure 1 and Figure 3 The follower plate 50 is provided with a support assembly 70 on the side opposite to the rotating side, and a rubber pad 71 is provided at the bottom of the support assembly 70. Regardless of which side the follower plate 50 is on, the side opposite to the rotating side needs to be supported on the overhead travelling vehicle. By providing the support assembly 70, the support stability of the follower plate 50 in various states is improved, and a rubber pad 71 is provided at the bottom of the support assembly 70 to increase the friction between the follower plate 50 and the overhead travelling vehicle, further improving the support stability, and preventing the follower plate 50 from rotating and causing injuries when people are stepping on it.

[0056] In some embodiments, a specific implementation of the support assembly 70 can be as follows: Figure 1 and Figure 3 See the structure shown. Figure 1 and Figure 3The support assembly 70 includes a plurality of first legs 72 and a plurality of second legs 73 arranged alternately. The bottom of the first leg 72 is inclined toward the side of the follower plate 50 away from the fixed plate 10, and the bottom of the second leg 73 is inclined toward the side of the follower plate 50 close to the fixed plate 10. The rubber pads 71 ​​are respectively arranged at the bottom of the first leg 72 and the second leg 73. The bottoms of the first leg 72 and the second leg 73 are inclined in two opposite directions to form a triangular stable support. When adjusting the follower plate 50, the first leg 72 and the second leg 73 are ensured to contact the ground, which helps to ensure the verticality of the follower plate 50 and is easy to adjust.

[0057] In some embodiments, an improved implementation of the auxiliary walking platform on the overhead traveling vehicle may be as follows: Figure 1 and Figure 3 See the structure shown. Figure 1 and Figure 3 , reinforcing ribs 80 are connected between the cover plate 11 and the fixed plate 10, and between the foot pedal 51 and the follower plate 50. Since the cover plate 11 is fixed on the fixed plate 10 and is perpendicular to the fixed plate 10, and the foot pedal 51 is fixed on the follower plate 50 and is perpendicular to the follower plate 50, by providing the reinforcing ribs 80, the cover plate 11 and the foot pedal 51 can be prevented from breaking, and their load-bearing capacity can be improved, thereby not restricting the weight of the personnel entering the overhead crane, and the safety factor is higher.

[0058] In some embodiments, an improved implementation of the auxiliary walking platform on the overhead traveling vehicle may be as follows: Figure 1 and Figure 3 See the structure shown. Figure 1 and Figure 3 The cover plate 11 and the fixing plate 10 are provided with a first fixing sleeve 81, respectively, and the two ends of the reinforcing rib 80 between the cover plate 11 and the fixing plate 10 are respectively inserted into the first fixing sleeve 81; the foot pedal 51 and the follower plate 50 are provided with a second fixing sleeve 82, respectively, and the two ends of the reinforcing rib 80 between the foot pedal 51 and the follower plate 50 are respectively inserted into the second fixing sleeve 82; the reinforcing rib 80 is used to be replaced with the first leg 72 or the second leg 73. Since there are multiple first legs 72 and second legs 73, the corresponding reinforcing ribs 80 can also be provided with multiple axial intervals along the first rotating shaft 20 or the second rotating shaft 40. After long-term use, if the first leg 72 or the second leg 73 or the reinforcing rib 80 is broken or damaged, it is necessary to transport tools from the ground for immediate maintenance, and the overhead crane needs to be stopped, which reduces production efficiency. At this time, the first leg 72 or the second leg 73 can be used as the reinforcing rib 80, or the reinforcing rib 80 can be disassembled and used as the first leg 72 or the second leg 73.

[0059] Specifically, a third fixing sleeve 52 for clamping the first leg 72 or the second leg 73 may also be provided on the follower plate 50 , thereby facilitating the loading and unloading of the first leg 72 and the second leg 73 .

[0060] It should be noted that Figure 1 and Figure 3 The exposed lengths of the reinforcing ribs 80 at different positions are shown to be different, but in reality the lengths of each reinforcing rib 80, the first leg 72 and the second leg 73 are the same. The reinforcing rib 80 is partially placed in the first fixing sleeve 81 or the second fixing sleeve 82, and the exposed length of the reinforcing rib 80 can be adjusted to adapt to the supporting length of the reinforcing rib 80 at different positions; the same is true for the first leg 72 and the second leg 73.

[0061] In some embodiments, an improved implementation of the transition plate 30 may be as follows: Figure 1 and Figure 3 See the structure shown. Figure 1 and Figure 3 The third side of the transition plate 30 is provided with a mounting plate 31, the third side is adjacent to the first side, the plate surface of the mounting plate 31 is perpendicular to the plate surface of the transition plate 30, and is used to connect with the fence of the overhead travelling vehicle. When used as a walking platform, the mounting plate 31 on the transition plate 30 can be connected to the fence of the overhead travelling vehicle by bolts or wires to prevent the transition plate 30 from sliding up and down, thereby improving the stability of the walking platform and reducing the tension of the user.

[0062] In the initial state, the mounting plate 31 is located at the top of the transition plate 30 to prevent interference with the cover plate 11; after deformation, when used as a walking platform, the mounting plate 31 is located at the bottom of the transition plate 30 and is further connected to the upper frame of the overhead travelling vehicle.

[0063] In some embodiments, a specific implementation of the mounting plate 31 may be as follows: Figure 1 and Figure 3 See the structure shown. Figure 1 and Figure 3 The mounting plate 31 includes a first plate 311 and a second plate 312. The first plate 311 is fixed to the transition plate 30; the second plate 312 is slidably connected to the first plate 311, and a mounting hole for connecting to the fence of the overhead travelling vehicle is provided on the top of the second plate 312. The overall length of the mounting plate 31 can be changed by adjusting the second plate 312 and the first plate 311 to adapt to different installation environments.

[0064] In some embodiments, an improved implementation of the first plate 311 may be as follows: Figure 1 and Figure 3 See the structure shown. Figure 1 and Figure 3The first plate 311 is provided with a slide groove 313 with an opening upward, and the second plate 312 is slidably matched with the slide groove 313. By placing the second plate 312 in the slide groove 313, the sliding path of the second plate 312 can be guided, the sliding process is more stable, and the verticality of the mounting plate 31 is ensured.

[0065] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
