[0029] The following describes the embodiments of the present invention in detail with reference to the accompanying drawings. However, the present invention can be implemented in many different ways as defined and covered by the claims.

[0030] The utility model provides an adjustable stepping device, aiming to solve the problems of complex operation and low working efficiency of existing equipment moving stepping devices.

[0031] like Figure 1 and Figure 2As shown, this embodiment provides an adjustable stepping device for moving the device 10. The bottom of the device 10 has a space for setting the adjustable stepping device. The adjustable stepping device includes at least two stepping legs 20 arranged on both sides of the device 10. The stepping legs 20 include a sliding shoe 1, a mounting body 2, a first moving mechanism 3, a second moving mechanism 4 and a third moving mechanism 5. The mounting body 2 is in sliding contact with the sliding shoe 1; the first moving mechanism 3 is arranged on the mounting body 2 along the first direction; the second moving mechanism 4 is slidingly arranged on the mounting body 2 along the first direction, the second moving mechanism 4 is connected to the output end of the first moving mechanism 3, and the second moving mechanism 4 is used to connect with the device 10, and the second moving mechanism 4 can drive the device 10 to move in the vertical direction; the third moving mechanism 5 is connected between the mounting body 2 and the sliding shoe 1, and the third moving mechanism 5 can push the mounting body 2 to slide relative to the sliding shoe 1 along a direction perpendicular to the first direction.

[0032] In actual operation, the two stepping legs 20 cooperate to achieve movement of the equipment 10 in a first direction, a direction perpendicular to the first direction, and a vertical direction. Specifically, the first movement mechanism 3 drives the second movement mechanism 4 to move the device in the first direction, the second movement mechanism 4 drives the device 10 in the vertical direction, and the third movement mechanism 5 pushes the mounting body 2 to slide relative to the sliding shoe 1 in a direction perpendicular to the first direction. This utility model enables the lifting, longitudinal movement, and lateral position adjustment of large-sized and heavy equipment 10, facilitating adjustment of the equipment 10's lateral position in a roadway. The third movement mechanisms in the two stepping legs operate in opposite directions and cooperate with each other to achieve tilting of the equipment, adapting to roadway turns and adjusting docking interfaces between different equipment 10. This eliminates the need for laying additional tracks or disassembling components, resulting in simple operation and high efficiency, reducing labor intensity and time. It also eliminates the need for winch wire ropes, minimizing safety hazards. For rack-type equipment 10, the adjustable stepping device can be embedded in the bottom to dock with the equipment 10 using internal space, or it can be adapted to the device by increasing the height of the bottom of the equipment 10. The adjustable stepping device may further include more than two stepping legs 20, each stepping leg 20 being evenly arranged on both sides of the device 10 to cooperate with adjusting the position of the device 10, thereby enhancing the stability of the adjustment process.

[0033] like Figures 3 to 6As shown, the mounting body 2 includes a mounting frame 2.1, a guide rod 2.2 and a movable guide rail 2.3. The bottom of the mounting frame 2.1 is provided with a slide 2.4 that is in sliding contact with the sliding shoe 1; the guide rod 2.2 is arranged on the mounting frame 2.1 perpendicular to the first direction; the movable guide rails 2.3 are all arranged on the mounting frame 2.1 along the first direction, and the second moving mechanism 4 is slidingly connected to the movable guide rail 2.3; the sliding shoe 1 is provided with a guide block 1.1 corresponding to the guide rod 2.2, and the guide block 1.1 is slidably sleeved on the guide rod 2.2; the third moving mechanism 5 is arranged at the end of the mounting frame 2.1 away from the slide 2.4, and the third moving mechanism 5 is hinged between the guide block 1.1 and the guide rod 2.2. The first movable mechanism 3 is capable of driving the second movable mechanism 4 to slide along the movable guide rail 2.3. The first movable mechanisms 3 in the two stepping legs 20 operate synchronously to adjust the position of the device 10 in the first direction. Furthermore, the third movable mechanism 5 is capable of applying a force to the guide block 1.1 to push the mounting frame 2.1 to slide relative to the sliding shoe 1 in a direction perpendicular to the first direction via the sliding plate 2.4, thereby adjusting the position of the device 10 perpendicular to the first direction. The use of the first movable mechanism 3 and the second movable mechanism 4 to adjust the position of the device 10 in the first direction and perpendicular to the first direction is simple to operate, easy to adjust, and can meet various requirements in actual operations. The third movable mechanism 5 is articulated with the guide block 1.1 and the guide rod 2.2, respectively, to release rotational freedom and improve the transmission efficiency of the third movable mechanism 5 in the direction perpendicular to the first direction.

[0034] Furthermore, the second moving mechanism 4 includes a lifting structure 4.1 and a walking wheel box 4.2. The lifting structure 4.1 includes an inner cylinder 4.1.1, an outer cylinder 4.1.2 and a lifting drive member 4.1.3. The inner cylinder 4.1.1 is hingedly arranged on the walking wheel box 4.2; the outer cylinder 4.1.2 is sleeved on the outside of the inner cylinder 4.1.1, and the two sides of the outer cylinder 4.1.2 are respectively provided with mounting plates 4.1.4 for connecting with the equipment 10; one end of the lifting drive member 4.1.3 is hinged to the outer cylinder 4.1.2, and the other end extends into the inner cylinder 4.1.1 and is hinged to the bottom wall of the inner cylinder 4.1.1; the walking wheel box 4.2 is slidably arranged on the guide block 1.1. The inner cylinder 4.1.1 slides up and down along the outer cylinder 4.1.2 under the action of the lifting drive 4.1.3, thereby driving the device 10 to move up and down. In actual operation, the two stepping legs 20 are first suspended on the device 10, and then the lifting drive 4.1.3 in the second moving mechanism 4 drives the inner cylinder 4.1.1 to drive the installation body 2 to contact the ground, and then the lifting drive 4.1.3 continues to run. Under the reaction force of the ground, the lifting drive 4.1.3 pushes the outer cylinder 4.1.2 to move vertically upward along the inner cylinder 4.1.1 to drive the bottom of the device 10 off the ground, so as to facilitate the subsequent adjustment of the position of the device 10 in the first direction and perpendicular to the first direction.

[0035] Furthermore, two guide cavities 2.3.1 arranged along the first direction are formed on the movable guide rail 2.3, the two guide cavities 2.3.1 are arranged back to back, and a guide surface 2.3.2 arranged along the first direction is provided on the top of the movable guide rail 2.3; the walking wheel box 4.2 includes a box body 4.2.1 and a walking wheel structure 4.2.2, the box body 4.2.1 is connected to the first moving mechanism 3, and an installation cavity is opened in the box body 4.2.1, the walking wheel structure 4.2.2 includes at least a large walking wheel B1 and two small walking wheels B2 rotatably arranged in the installation cavity, and the large walking wheel B1 is in rolling contact with the guide surface 2.3.2, and the two small walking wheels B2 are respectively arranged in the two guide cavities 2.3.1 and in rolling contact with the top wall of the guide cavity 2.3.1. The large walking wheel B1 and the small walking wheel B2 cooperate to form an anti-slip structure between the walking wheel structure 4.2.2 and the moving guide rail 2.3, which can not only realize the sliding connection between the walking wheel structure 4.2.2 and the moving guide rail 2.3, but also enhance the cooperation stability between the walking wheel structure 4.2.2 and the moving guide rail 2.3.

[0036] There are one or more running wheel structures 4.2.2, all of which are located within the mounting cavity and evenly distributed on both sides of the lifting structure 4.1. The combination of multiple running wheel structures 4.2.2 further enhances the stability of the sliding fit between the running wheel box 4.2 and the movable guide rail 2.3, distributes the applied force, and improves smoothness of movement.

[0037] Specifically, mounting plate 4.1.4 includes a mounting portion A1 and multiple reinforcement portions A2. Mounting portion A1 is vertically arranged and has multiple evenly distributed mounting holes for connection to device 10. Multiple reinforcement portions A2 are vertically spaced and connected between outer cylinder 4.1.2 and mounting portion A1. The multiple reinforcement portions A2 enhance the connection strength between mounting portion A1 and outer cylinder 4.1.2. Mounting portion A1 is connected to device 10 via multiple mounting holes, ensuring a strong connection between device 10 and mounting portion A1, thereby enhancing safety and stability during operation.

[0038] Furthermore, there are one or more first moving mechanisms 3 and second moving mechanisms 4, each of which is arranged correspondingly to the first moving mechanism 3 and the second moving mechanism 4. There are one or more third moving mechanisms 5, each of which is arranged at intervals along the first direction. Increasing the number of moving mechanisms enhances both the stability of the movement process and the load-bearing capacity of the overall device, making it suitable for moving large equipment 10.

[0039] The mounting body 2 also includes a horizontal hinge seat 2.5 and a vertical hinge seat 2.6. The horizontal hinge seat 2.5 device 10 is mounted on the mounting frame 2.1, and the vertical hinge seat 2.6 is mounted on the second movable mechanism 4. The first movable mechanism 3 is hinged between the horizontal hinge seat 2.5 and the vertical hinge seat 2.6. The horizontal hinge seat 2.5 includes two horizontally arranged horizontal lugs. One end of the first movable mechanism 3 extends between the two horizontal lugs and is hinged to the two horizontal lugs via a rotating shaft to release the horizontal rotational freedom of the first movable mechanism 3. The vertical hinge seat 2.6 includes two vertical lugs of the vertical device 10. The other end of the first movable mechanism 3 extends between the two vertical lugs and is hinged to the two vertical lugs via a rotating shaft to release the vertical rotational freedom of the first movable mechanism 3. This ensures the transmission efficiency of the driving force of the first movable mechanism 3 and reduces the force on the first movable mechanism 3 in the non-stroke direction. In this embodiment, the first moving mechanism 3, the lifting drive member 4.1.3 and the third moving mechanism 5 can all adopt cylinder drive members.

[0040] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention.
