[0039] The concept, specific structure and technical effects of the utility model will be described clearly and completely in combination with the embodiments and the drawings, so as to fully understand the purpose, scheme and effect of the utility model. It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict. The same reference numerals used in the drawings indicate the same or similar parts.

[0040] It should be noted that, unless otherwise specified, when a feature is referred to as being "fixed" or "connected" to another feature, it can be directly fixed or connected to the other feature, or indirectly fixed or connected to the other feature. In addition, the up, down, left, right and other descriptions used in the utility model are only relative to the mutual position relationship of the components of the utility model in the drawings.

[0041] Reference Figures 1 to 8 A footrest tool suitable for uneven ground, comprising a lower frame 2 and an upper frame 1, four first supporting feet 25 are installed around the bottom end of the lower frame 2, and a first pedal 23 is horizontally arranged in the middle of the lower frame 2. One end of the upper frame 1 is hingedly connected to the upper end of the lower frame 2, and an end plate 13 is arranged at this end of the upper frame 1, and a second pedal 12 parallel to the end plate 13 is horizontally arranged in the middle of the upper frame 1. The hinge axis of the upper frame 1 and the lower frame 2 is horizontally arranged, so that the upper frame 1 can be flipped up or down relative to the lower frame 2.

[0042] The upper frame 1 has an open state, at this time, the upper frame 1 is flipped up to above the lower frame 2, so that the height of the overall structure is increased, and the end plate 13 is flipped up to above the first pedal 23, the first pedal 23, the end plate 13 and the second pedal 12 can be arranged in order from bottom to top and form a three-step structure. The footrest tool of the present scheme is a ladder with a three-step structure after being opened, and the ladder is a right triangle, and the first pedal 23, the end plate 13 and the second pedal 12 are evenly distributed on the hypotenuse of the right triangle. The footrest tool with such structure not only can be used in the corner position, but also ensures the stability and safety of the overall structure. The first pedal 23, the end plate 13 and the second pedal 12 are used to form corresponding step surfaces, which facilitates the maintenance personnel to climb onto the car hook maintenance platform for maintenance work. When the upper frame 1 is in the open state, the upper end of the lower frame 2 can abut and support one end of the bottom of the upper frame 1 in this state.

[0043] In addition, when the upper frame 1 is in the open state, the bottom of the upper frame 1 is further connected with two vertically and spaced second supporting feet 17, which are connected to the other end of the bottom of the upper frame 1 away from the lower frame 2, and the second supporting feet 17 support the upper frame 1 together with the lower frame 2, so that the state of the upper frame 1 is more stable, and the maintenance personnel can safely go up and down the maintenance platform to complete various maintenance work. The height of each first supporting foot 25 and each second supporting foot 17 can be adjusted, for example, by using a telescopic rod with adjustable length to achieve height adjustment. By adjusting the height of each first supporting foot 25 and each second supporting foot 17, the first tread plate 23, the end plate 13 and the second tread plate 12 can be in a horizontal state, so as to be suitable for various slope grounds. The height of each first supporting foot 25 and each second supporting foot 17 can also be adjusted according to the height of the maintenance platform relative to the ground or the height of other platforms that need to be reached, so that the first tread plate 23, the end plate 13 and the second tread plate 12 can be raised or lowered relatively, thereby approaching the platform that needs to be reached, so that the maintenance personnel can smoothly reach the maintenance platform or other platforms that need to be reached. For the coupler maintenance platform, since the coupler maintenance platform is more than one meter away from the ground and has a relatively small height, the height adjustment range of the first supporting foot 25 and the second supporting foot 17 is not large, and the phenomenon that the height of the first tread plate 23 is too large to be stepped on will not occur. For other higher platforms, the height of the upper frame 1 and the lower frame 2 can be increased and tread plate structures can be added at corresponding positions to adapt to it.

[0044] The lower end of each first supporting foot 25 and each second supporting foot 17 in contact with the ground is hingedly connected with a supporting pad 18, and the bottom surface of the supporting pad 18 can be matched with the ground by rotating the supporting pad 18, so as to be suitable for uneven ground.

[0045] The footrest tool of the scheme can be installed on slopes with different slopes, can match different patterns according to different labor protection shoes, meets the use requirements of multiple sections and various labor protection shoes, and has wide applicability.

[0046] After the footrest tool of the scheme is put into use, a new channel for going up and down the coupler maintenance platform is opened, the maintenance personnel can conveniently, quickly and safely go up and down the maintenance platform to complete various maintenance work, not only can save the time for going up and down the maintenance platform and improve the efficiency of daily maintenance work, but also can avoid falling down of the maintenance personnel and protect the safety of the maintenance personnel.

[0047] The footrest tool of the scheme adopts a folding structure, has simple structure, practical function, low manufacturing cost and simple installation, has high practicality and safety, and has the advantages of work efficiency and economic benefit, can be conveniently and quickly opened and folded, is convenient for quickly carrying out work in different occasions, and quickly leaves the scene after the work is completed.

[0048] Specifically, the upper frame 1 is turned down to the second pedal 12 below the end plate 13, and the upper frame 1 is in a folded state. After the footrest tool suitable for uneven ground is used, the upper frame 1 can be turned down relative to the lower frame 2.

The upper frame 1 and the lower frame 2 are further provided with a locking device for fixing the upper frame 1 and the lower frame 2, so that the upper frame 1 and the lower frame 2 will not rotate relative to each other when the footrest tool is lifted, thereby ensuring that the tool will not open after being folded, and ensuring safety during movement. The lock 3 can adopt a conventional lock 3 structure, and when the lock 3 is opened, the secondary protection of the lock 3 is first rotated to the open position, and then the lock 3 is opened.

[0050] Specifically, the footrest tool suitable for uneven ground further comprises two parallel and spaced first support columns 14, one end of each of the two first support columns 14 is hingedly connected to the side of the end plate 13 away from the second pedal 12, and the other end is connected to the end of the corresponding second support leg 17 away from the support pad 18. When the upper frame 1 is in a folded state, the side of the end plate 13 away from the second pedal 12 forms the bottom surface of the upper frame 1, and the first support column 14 can be rotated to make the first support column 14, the second support leg 17 and the support pad 18 close to the end plate 13, thereby reducing the space occupation. The handle 19 can be arranged in the central region of the end plate 13 and between the two first support columns 14, so as to avoid hindering the folding process caused by the rotation of the first support column 14 towards the end plate 13, and facilitate the gripping of the handle 19. The rotation axis of the first support column 14 is parallel to the rotation axis of the upper frame 1, and the first support column 14 is perpendicular to the axis.

After the upper frame 1 is opened, the foldable hinge support 16 can be used for supporting and fixing between the first fixed rod 15 and the end plate 13. The arrangement of the foldable hinge support 16 makes the first support column 14 not skewed in the open state, and makes the support of the first support column 14 to the end plate 13 more stable. When the two first support columns 14 are turned up synchronously, each foldable hinge can be opened synchronously.

[0052] Specifically, each of the first support feet 25 and each of the second support feet 17 are structurally identical, each of the first support feet 25 is provided with a spherical portion at one end away from the lower frame 2, and each of the second support feet 17 is provided with a spherical portion at one end away from the upper frame 1.

Each of the through holes is provided with an internal thread, and each of the connecting rods 251 is threadedly connected to the first support column 14 or the lower frame 2 by being inserted into the through hole. In use, the connecting rods 251 can be rotated to change the distance between each of the support pads 18 and the upper frame 1 or the lower frame 2, so that the height of each of the first support feet 25 and each of the second support feet 17 can be adjusted. The thread in the through hole is a self-locking thread, so as to prevent the connecting rod 251 from moving up and down.

[0054] Specifically, the first support feet 25 further include lock nuts 252 corresponding to the connecting rods 251, and the lock nuts 252 are threadedly connected to the outer side of the connecting rods 251 and abut against the outer end of the through hole at the upper end.
