Description

Technical Field

[0001] The present invention relates to the technical field of working equipment, and particularly to an anti-tipping mobile platform. Background Art

[0002] The mobile platform on the traditional arm section completely depends on a set of running rollers and another pair of rollers perpendicular to the running direction of the running rollers for guiding. The restraint on the mobile platform is often insufficient, which causes the trolley to roll over under extreme conditions. At present, there are few devices and methods at home and abroad to avoid the risk of rollover. They mainly limit the lateral displacement of the moving machine, but cannot prevent longitudinal rollover, or have high costs, complex installations, and limited protection effects. At the same time, the working coverage space of the mobile platform on the arm section is often insufficient, limited by the length direction of the arm section, and there are quite a few dead corners. In addition, for driving the mobile platform, chains, belts, and multiple steel wire ropes are mostly used to ensure stability, resulting in high costs and complex installations. Summary of the Invention

[0003] To solve the above technical problems, the present invention provides an anti-tipping mobile platform, which is used to solve the defect that it is difficult for the existing technology to resist disturbances in multiple directions during the movement of the mobile platform on the arm section and to achieve more working coverage space.

Detailed implementation mode

[0035] To facilitate the understanding of the technical solution of the present invention, the following will be described in detail in combination with the accompanying drawings and specific embodiments.

[0036] Embodiment 1

[0037] As Figure 1-2 shown, an anti-tilting mobile platform includes an arm section and a mobile platform, and the mobile platform can move relative to the arm section;

[0038] The arm section is provided with main chord members. The main chord members include two upper main chord members 1 and two lower main chord members 2. There is a certain distance between the upper main chord member 1 and the lower main chord member 2 on the same side, forming an accommodation space; the mobile platform includes a platform body 3 and wheel frames 4 arranged on the left and right sides of the platform body 3. Among them, the wheel frame 4 on the left cooperates with the upper main chord member 1 and the lower main chord member 2 on the left, and the wheel frame 4 on the right cooperates with the upper main chord member 1 and the lower main chord member 2 on the right.

[0039] As Figures 10-13 shown, the wheel frame 4 is provided with a vertical web member 4-1, an inner wheel frame 4-2, inner roller groups, and an outer roller group 4-3. The vertical web member 4-1 is welded below both sides of the platform body 3. The inner wheel frame 4-2 is arranged between the two vertical web members 4-1. Inner roller groups are provided on both the upper and lower layers of the inner wheel frame 4-2. The inner roller groups on the upper and lower layers respectively abut against the upper main chord member 1 and the lower main chord member 2. The outer roller group 4-3 is arranged on the vertical web member 4-1 and abuts against the side surface of the main chord member. Specifically, the inner roller groups include a first inner roller group 4-4 arranged above the inner wheel frame 4-2 and a second inner roller group 4-5 arranged below the inner wheel frame 4-2. The first inner roller group 4-4 abuts against the lower surface of the upper main chord member 1, the second inner roller group 4-5 abuts against the upper surface of the lower main chord member 2, and the outer roller group 4-3 abuts against the outer side surface of the main chord member. The wheel frames 4 on the left and right sides cooperate with the upper main chord members 1 and the lower main chord members 2 on the left and right sides to support and limit the platform body 3, preventing the platform body 3 from tipping or shifting.

[0040] Among them, the wheel carrier 4 on each side includes two pairs of inner roller groups. An outer roller group 4-3 is provided between the two pairs of inner roller groups. Each group of the first inner roller group 4-4 and the second inner roller group 4-5 includes a roller seat 4-6 and an inner roller 4-7. The outer roller group 4-3 also has two pairs, with two outer rollers 4-8 in each pair; that is, there are 8 inner rollers 4-7 on each side, 4 on the upper and lower sides respectively, and there are 4 outer rollers 4-8. At the same time, mounting holes are provided on the roller seat 4-6. One end of the inner roller carrier 4-2 is inserted into the mounting hole of the roller seat 4-6, and the roller seat 4-6 can rotate relative to the inner roller carrier 4-2. Inner rollers 4-7 are provided at both ends of the roller seat 4-6. The top of the roller seat 4-6 is movably fitted with a cover plate 4-10. The cover plate 4-10 is connected to the inner roller carrier 4-2 by bolts to prevent the inner roller carrier 4-2 from disengaging from the roller seat 4-6; limiting baffle plates 4-9 for restricting the rotation amplitude of the roller seat 4-6 are provided inside the roller seat 4-6 at positions on both sides of the inner roller carrier 4-2. That is to say, the inner roller can swing slightly, facilitating abutting and limiting against the main chord when tilting or offsetting.

[0041] If it tilts to the left during use, the outer roller group 4-3 on the right side will abut against the upper main chord 1 on the right side to prevent the mobile platform from tilting to the left. At the same time, the second inner roller group 4-5 on the left side abuts against the lower main chord 2 on the left side, and the first inner roller group 4-4 on the right side abuts against the lower surface of the upper main chord 1 on the right side; if it tilts forward during use, the inner roller 4-7 of the first inner roller group 4-4 located at the rear can abut against the lower surface of the upper main chord, and the inner roller 4-7 of the second inner roller group 4-5 located at the front can abut against the lower surface of the lower main chord to prevent the mobile platform from tilting forward. When tilting to other angles, the first inner roller group 4-4, the second inner roller group 4-5, and the outer roller group 4-3 cooperate with the main chord at the same time for limiting. To sum up, when this application is in use, at least 8 inner rollers 4-7 will abut against the main chord for limiting, ensuring the planar horizontality and stability of the mobile platform during operation and various eccentric operations.

[0042] As Figures 1-3 shown, a driving mechanism 5, a steel wire rope 6, and a steering wheel 7 are further provided on the boom section. The driving mechanism 5 is placed on the side of the boom section close to the tower body, and the steering wheel 7 is placed at both ends of the boom section; the mobile platform further includes a rope loop 8 and a ratchet rotating cylinder 9. The rope loop 8 is arranged on the side of the platform body 3 close to the tower body, and the ratchet rotating cylinder 9 is arranged on the side of the platform body 3 far from the tower body; one end of the steel wire rope 6 is connected to the rope loop 8, and the other end is sequentially wound around the driving mechanism 5 and two steering wheels 7 and then connected to the ratchet rotating cylinder 9. The driving mechanism 5 drives the mobile platform to move back and forth through the steel wire rope 6.

[0043] As Figures 4-9As shown, a track arm section 10 and a telescopic arm section 11 are provided on the arm section. An oil cylinder 12 is provided between the telescopic arm section 11 and the track arm section 10. The telescopic arm section 11 can be driven to extend forward or retract backward by the oil cylinder 12.

[0044] The track arm section 10 includes single plates and web members 10-1. A rectangular-truss-like structure is formed by welding between two single plates through the web members 10-1. Each single plate includes a main chord, a straight web member 10-2, and an L-shaped ear plate 10-3. Connectors 10-4 are welded to both ends of the main chord. The straight web member 10-2 is arranged on the main chord. The L-shaped ear plate 10-3 is connected between the main chord and the straight web member 10-2. On the premise of ensuring load-bearing, part of the main chord is placed outside, leaving two complete adjacent planes for the rollers to move.

[0045] The telescopic arm section 11 includes a special track section 11-1 and an extending section 11-2. The special track section 11-1 is provided with a first friction block 11-1-1 and a first oil cylinder ear plate 11-1-2. The first friction block 11-1-1 is connected to the inner side of the special track section 11-1 at eight positions by bolts. The first oil cylinder ear plate 11-1-2 is arranged on the special track section 11-1 near the tower body side. One end of the oil cylinder 12 is hinged to the first oil cylinder ear plate 11-1-2.

[0046] The extending section 11-2 is in sliding fit with the special track section 11-1. The extending section 11-2 is provided with a second friction block 11-2-1 and a second oil cylinder ear plate 11-2-2. Both ends of the oil cylinder 12 are hinged to the first oil cylinder ear plate 11-1-2 and the second oil cylinder ear plate 11-2-2 by pin shafts.

[0047] The special track section 11-1 and the extending section 11-2 support and slide relative to each other through the first friction block 11-1-1 and the second friction block 11-2-1.

[0048] An extending platform 11-3 is provided on the extending section 11-2. The extending platform 11-3 is arranged on the far tower body side. The width of the extending platform 11-3 is relatively large, which can provide a relatively large area and cooperate with the telescopic function provided by the telescopic arm section 11 to make up for the working space that the mobile platform cannot cover to a certain extent.

[0049] A crane 13 is provided at the upper end of the mobile platform, which can move objects up and down the platform and the arm section.

[0050] The above is only the preferred embodiment of the present invention. The protection scope of the present invention is subject to the scope defined by the claims. Several improvements and refinements made by those skilled in the art without departing from the spirit and scope of the present invention should also be regarded as within the protection scope of the present invention.
