Abstract
Description
Technical Field
[0001] The invention relates to a welding platform, in particular to a mobile welding operation platform. Background Art
[0002] When on-site operators perform welding operations in pumped storage power station diversion tunnels, intermediate tunnels, tailwater tunnels and other places, they often need to use welding platforms to support them, so that operators can perform welding operations on components at different positions around the tunnel. On this basis, the existing welding platform is mainly composed of a main body and a support frame extending outward. The support frame is fixed on both sides and the top of the main body according to the requirements of the welding position, and completely covers the surrounding area of the tunnel, so that operators can climb up and down ladders to any support frame for welding operations. There are rollers at the bottom of the welding platform. When the welding platform needs to be moved, the horizontal drive device can drive the welding platform to translate in the tunnel, thereby realizing the electric drive displacement function.
[0003] However, the defect of this welding platform is that, since the welding platform is formed by welding or bolting the main body and the support frame, and the support frame is extended to the outside of the main body through a cantilever structure, the support frame is prone to damage at the connection parts after long-term use, or the support frame itself is bent and deformed, which causes the operator standing on the support frame to be at risk of falling, and the safety is poor. On the other hand, since the outer dimensions of the welding platform cannot be adjusted, and the outer dimensions of different tunnels are different, the manufacturer needs to produce a welding platform of corresponding size for each tunnel, which reduces the versatility of the welding platform.
[0004] Therefore, the existing welding work platform has the problems of poor safety and versatility. Summary of the invention
[0005] The purpose of the present invention is to provide a mobile welding work platform which has the characteristics of good safety and versatility.
[0006] The technical solution of the present invention is as follows: a mobile welding work platform comprises two support frames which are symmetrically arranged on the left and right, the lower ends of the support frames are connected with rollers, a first welding platform is connected between the two support frames, a second welding platform is connected to the outer sides of the two support frames, and threading holes are provided on the first welding platform and the second welding platform; the top of the support frame is connected with a steel wire rope via a steel wire rope rack, one end of the steel wire rope is fixedly connected to the steel wire rope rack, the other end of the steel wire rope passes through the threading holes of the first welding platform and the second welding platform in turn and is then connected to the steel wire rope rack via a spring assembly, and the steel wire rope is provided with an anti-fall assembly for temporarily limiting the first welding platform and the second welding platform.
[0007] In the aforementioned mobile welding work platform, the support frame is spliced by H-shaped steel, and is respectively provided with a first slide groove for connecting the first welding platform and a second slide groove for connecting the second welding platform. The inner end of the first welding platform extends into the first slide groove and is bolted to the support frame, and the inner end of the second welding platform extends into the second slide groove and is bolted to the support frame.
[0008] In the aforementioned mobile welding work platform, the anti-fall assembly includes an anti-fall rod welded on the first welding platform or the second welding platform, the anti-fall rod is provided with a wire hole for the wire rope to pass through, and the first wire rope clamp is fixedly connected to the wire rope below the wire hole.
[0009] In the aforementioned mobile welding work platform, the spring assembly includes a driving plate located above the wire rope rack, the two ends of the driving plate are bolted to the wire rope rack, a compression spring is provided between the driving plate and the wire rope rack and is sleeved on the outside, and the end of the wire rope is connected to a second wire rope clamp after passing through the wire rope rack and the driving plate.
[0010] In the aforementioned mobile welding work platform, the first welding platform includes two platform frames arranged symmetrically on the left and right, the outer ends of the platform frames are connected to the support frames via tripods, an I-shaped intermediate frame is bolted between the two platform frames, and a plurality of first mounting holes for adjusting the mounting position of the intermediate frame are distributed on the platform frames.
[0011] In the aforementioned mobile welding work platform, the cross-sectional shape of the tripod is C-shaped, and a plurality of second mounting holes for adjusting the mounting height of the first welding platform are distributed on the tripod. The upper end of the support frame is bolted to the side walls of the anti-fall rod, and the anti-fall rod is provided with an opening for the tripod to pass through.
[0012] In the aforementioned mobile welding work platform, a plurality of anti-falling components are spaced apart at the lower end of the tripod along the height direction.
[0013] In the aforementioned mobile welding work platform, the second welding platform is spliced by channel steel, and a plurality of third mounting holes for adjusting the installation height of the second welding platform are distributed on the support frame outside the second slide slot, and the second welding platform is connected to the support frame by bolts through the third mounting holes; the threading holes and the third mounting holes on the second welding platform are staggered inwards and outwards in the horizontal direction.
[0014] Compared with the prior art, the present invention has the following characteristics:
[0015] (1) The present invention can realize the anti-falling function of the first welding platform and the second welding platform after installation through the structural coordination of the wire rope frame, the wire rope and the anti-falling assembly, that is, the first welding platform and the second welding platform are connected to the support frame by bolts in a normal state, and the anti-falling assembly is not subjected to force at this time; and when the first welding platform and the second welding platform fall downward due to damage to the bolt connection part or their own compression deformation, they can be towed and lifted by the coordination of the anti-falling assembly and the wire rope, so that the operator has sufficient time to quickly evacuate the first welding platform or the second welding platform, and then repair the damaged area, thereby ensuring the safety of the present invention;
[0016] (2) By limiting the structure of the spring assembly, the driving plate can be in a high position under normal conditions. When the first welding platform or the second welding platform falls, the gravity of the first welding platform or the second welding platform will first pull the driving plate to a low position, and then realize the lifting function. This will make the operator of the first welding platform or the second welding platform feel obvious vibration when the first welding platform or the second welding platform falls, thereby playing a warning role and reminding the operator to evacuate quickly, further improving the safety of the present invention;
[0017] (3) Through the structural limitation of the first welding platform and the second welding platform, the manufacturer can adjust the installation height of the two on the support frame respectively; through the connection structure limitation of the platform frame and the intermediate frame, the spacing distance between the support frames can be adjusted, that is, the width of the welding work platform can be adjusted; and under the above cooperation, the manufacturer can adjust the height and width of the welding work platform according to the tunnel shape, thereby improving the versatility of the present invention;
[0018] (4) On the basis of the above, the operator can also use the wire rope to pull, lift and reposition any of the first welding platform and the second welding platform in the tunnel; therefore, when the welding work platform cannot be normally moved and advanced due to the restrictions of the facilities in the tunnel, or the height of the first welding platform and the second welding platform cannot match the welding position, the operator can adjust the installation height of the first welding platform and the second welding platform without using external lifting equipment, thereby improving the applicability of the present invention;
[0019] Therefore, the present invention has the characteristics of good safety and versatility. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The support frame 1 is spliced by H-shaped steel, and is respectively provided with a first slide groove 101 for connecting the first welding platform 3 and a second slide groove 102 for connecting the second welding platform 4. The inner end of the first welding platform 3 extends into the first slide groove 101 and is bolted to the support frame 1, and the inner end of the second welding platform 4 extends into the second slide groove 102 and is bolted to the support frame 1; after installation, the steel wire rope 7 is arranged to be staggered left and right with the first slide groove 101.
[0027] The anti-fall assembly includes an anti-fall rod 8 welded on the first welding platform 3 or the second welding platform 4. The anti-fall rod 8 can be made of channel steel and reinforced with reinforcing ribs. The anti-fall rod 8 is provided with a wire hole for the wire rope 7 to pass through. The first wire rope clamp 9 is fixedly connected to the wire rope 7 below the wire hole.
[0028] The spring assembly includes a drive plate 10 located above the wire rope rack 6, both ends of the drive plate 10 are bolted to the wire rope rack 6, a compression spring 11 is provided between the drive plate 10 and the wire rope rack 6 and is sleeved on the outside, and the end of the wire rope 7 is connected to a second wire rope clamp 12 after passing through the wire rope rack 6 and the drive plate 10.
[0029] The first welding platform 3 includes two platform frames 301 symmetrically arranged on the left and right. The outer ends of the platform frames 301 are connected to the support frame 1 via the tripod 302. An I-shaped intermediate frame 303 is bolted between the two platform frames 301. A plurality of first mounting holes 304 for adjusting the mounting position of the intermediate frame 303 are distributed on the platform frames 301.
[0030] The cross-sectional shape of the tripod 302 is C-shaped, and a plurality of second mounting holes 305 for adjusting the mounting height of the first welding platform 3 are distributed on the tripod 302. The upper end of the support frame 1 is bolted to the side walls of the anti-fall rod 8, and the anti-fall rod 8 is provided with an opening for the tripod 302 to pass through.
[0031] The lower end of the tripod 302 is provided with a plurality of anti-falling components spaced apart along the height direction.
[0032] The second welding platform 4 is spliced by channel steel, and a plurality of third mounting holes 103 for adjusting the installation height of the second welding platform 4 are distributed on the support frame 1 outside the second slide groove 102. The second welding platform 4 is bolted to the support frame 1 via the third mounting holes 103; the threading holes 5 and the third mounting holes 103 on the second welding platform 4 are staggered inward and outward along the horizontal direction.
[0033] Working principle of the present invention: When the present invention is used, the operator first adjusts the installation height of the first welding platform 3 and the second welding platform 4 on the support frame 1, and the extension position of the intermediate frame 303 on the platform frame 301. Then, the wire rope 7 is passed through the threading holes 5 of each of the first welding platform 3 and the second welding platform 4 in sequence, and the two ends are fixed on the wire rope frame 6, and the wire rope 7 is in a tensioned state after installation. After the wire rope 7 is fixed, the operator then fixes each first wire rope clamp 9 on the wire rope 7 below the threading hole 5, so that the first wire rope clamp 9 and the bottom surface of the anti-fall rod 8 cooperate with each other after being fixed.
[0034] The first welding platform 3 and the second welding platform 4 are bolted to the support frame 1 under normal conditions, and the first wire rope clamp 9 and the wire rope 7 are not stressed, and the compression spring 11 remains in a natural state. When any of the first welding platform 3 or the second welding platform 4 falls downward due to damage to its connection part, the anti-falling rod 8 will apply a downward squeezing force to the first wire rope clamp 9 below after falling, so that the end of the wire rope 7 close to the second wire rope clamp 12 is pulled down. After the wire rope 7 is pulled, it drives the driving plate 10 to overcome the elastic force of the compression spring 11 and move downward. When the compression spring 11 is in the extreme compression position, the driving plate 10 is in a low position and limits the wire rope 7, so that the cooperation of the wire rope 7 and the first wire rope clamp 9 is used to temporarily lift the fallen first welding platform 3 or the second welding platform 4 to prevent the platform from continuing to fall and causing damage. When the platform falls, it will move downward slightly and then stabilize again. The operators standing on the platform will be able to discover it in time, so they can quickly leave the faulty platform and repair it, improving the safety of the operators.
[0035] When the operator needs to temporarily adjust the height of the first welding platform 3 or the second welding platform 4 during operation, the operator can also control the lifting and lowering of one end of the wire rope 7 after removing part of the first wire rope clamp 9 and the second wire rope clamp 12, so that the platform slides up and down along the first slide groove 101 or the second slide groove 102 under the cooperation of the wire rope 7 and the first wire rope clamp 9. When the platform moves to the specified height, the operator first re-fixes the end of the wire rope 7 on the wire rope frame 6, and then installs the connecting bolts between the platform and the support frame. During the bolt installation process, the platform can be temporarily lifted by the cooperation of the wire rope 7 and the first wire rope clamp 9, thereby facilitating the installation of the operator. Since the above operation does not require the assistance of a sling, the operator can complete the adjustment of the platform height in a narrow tunnel space, which effectively improves the applicability of the welding work platform.
