Description

Technical Field

[0001] This invention belongs to the field of structural technology of profile bending equipment, and specifically relates to a mobile platform for profile bending equipment. Background Technology

[0002] Profile bending equipment is a key special forming equipment widely used in aviation, aerospace, automotive, and rail transportation fields. It is typically quite large, and to facilitate operator access to the equipment and materials for installation and testing, it is often equipped with a platform. However, because these platforms are designed specifically for profile bending equipment, they lack versatility, requiring redesign and remanufacturing when production lines or equipment are adjusted. Furthermore, existing platforms have structural shortcomings. For example, the integral rigid connection structure used in these platforms is heavy and lacks flexibility, often leading to decreased accuracy and movement jamming due to wear and tear over long-term use. They also pose a risk of failure when the foundation of the profile bending equipment settles. Some existing technologies increase strength by increasing plate thickness and supporting structures to ensure long-term reliability, but this further increases weight and material costs. Summary of the Invention

[0003] In view of this, and in response to the technical problems existing in the field, the present invention provides a mobile platform for a profile bending equipment, which adopts a bridge structure spanning a pair of parallel guide rails, including: a left trolley, a right trolley, left and right platforms, a middle platform, a main workbench, and a staircase. The left and right trolleys are slidably mounted on a guide rail; the left trolley is connected to the left platform and the right trolley is connected to the right platform via connecting rods. The middle platform is connected to the left and right platforms respectively, forming a whole that spans between the two guide rails; the main workbench is set on the middle platform and is used to support personnel to perform the main operations. Stairs are provided on both the left and right platforms to allow people to move up and down the platforms.

[0004] Furthermore, the middle step platform adopts a movable design, with rollers on its left and right sides, which are used to cooperate with the slide rails set on the right side of the left step platform and the left side of the right step platform to achieve sliding parallel to the direction of the guide rails.

[0005] Furthermore, the rollers on both sides of the middle platform specifically include the lower vertical rollers and the side horizontal rollers; the slide rails on the left and right platforms include the lower slide rails and the side slide rails corresponding to the rollers.

[0006] Furthermore, the stairs on the left and right platforms specifically include stairs that are parallel to the guide rails in the vertical direction, and stairs located outside the two guide rails and perpendicular to the guide rails in the vertical direction.

[0007] Furthermore, the left and right steps are slidably connected to the guide rails.

[0008] Furthermore, the left and right steps do not contact the guide rails, and the three of them, together with the middle step, are suspended above the parallel guide rails.

[0009] Furthermore, the distance between the left trolley and the left footrest, as well as the distance between the right trolley and the right footrest, can be adjusted using the connecting rod.

[0010] Furthermore, the left and right pedals are connected to the middle pedal by a hinged structure to allow the middle pedal to twist in the horizontal direction.

[0011] Furthermore, the left and right platforms and the middle platform all adopt a height-adjustable structure to meet the operational requirements of the equipment position and height, as well as to adjust the tilt angle of the middle platform.

[0012] Furthermore, a guardrail is installed on the central platform.

[0013] The movable platform of the profile bending equipment provided by the present invention has stronger applicability than the prior art. It can meet the operation requirements of equipment frames of different sizes and specifications, and can adjust different operating angles and positions through the different steps and heights of each platform. This avoids the repeated design and construction of platforms when updating production lines and equipment, and effectively reduces the required material and processing costs.

[0015] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0016] The movable platform of the profile bending equipment provided by this invention is as follows: Figure 1 As shown, a bridge structure spanning a pair of parallel guide rails is adopted, including: left trolley, right trolley, left and right steps, middle step, main workbench and stairs; The left and right trolleys are slidably mounted on a guide rail; the left trolley is connected to the left platform and the right trolley is connected to the right platform via connecting rods. The middle platform is connected to the left and right platforms respectively, forming a whole that spans between the two guide rails; the main workbench is set on the middle platform and is used to support personnel to perform the main operations. Stairs are provided on both the left and right platforms to allow people to move up and down the platforms.

[0017] In a preferred embodiment of the present invention, the intermediate step adopts the following... Figure 2 The movable design shown has rollers on both the left and right sides, which cooperate with the slide rails on the right side of the left footrest and the left side of the right footrest to achieve sliding parallel to the direction of the guide rails.

[0018] In a preferred embodiment of the present invention, the rollers on both sides of the middle step specifically include a lower vertical roller and a side horizontal roller; the slide rails on the left and right steps include a lower slide rail and a side slide rail corresponding to the rollers.

[0019] In a preferred embodiment of the present invention, the stairs on the left and right steps specifically include stairs that are parallel to the guide rails in the vertical direction, and stairs that are located outside the two guide rails and perpendicular to the guide rails in the vertical direction.

[0020] In a preferred embodiment of the present invention, the left and right steps are slidably connected to the guide rails, so that the entire step can move on the parallel guide rails; alternatively, the left and right steps can not contact the guide rails, and the three steps are suspended above the parallel guide rails.

[0021] In a preferred embodiment of the present invention, the distance between the left trolley and the left footrest, and the distance between the right trolley and the right footrest, can both be adjusted using the connecting rod.
