Description

Technical Field

[0001] This utility model relates to the technical field of high-altitude operation equipment for the construction of steel-concrete tied arches, specifically a high-altitude adjustable welding operation platform for steel-concrete tied arches. Background Technology

[0002] High-altitude operations for steel-concrete composite tied arch bridges refer to various work activities carried out in environments with high altitudes or large height differences during the construction of steel-concrete composite tied arch bridges. The adjustable high-altitude welding platform for steel-concrete composite tied arch bridges is a type of high-altitude work equipment specifically designed for the construction of steel-concrete composite tied arch bridges, primarily used for welding operations.

[0003] In existing steel-concrete composite tied arch construction, the working platform can only be adjusted in height, which limits its expansion capabilities. When working on adjacent external areas, the entire platform needs to be moved.

[0004] Therefore, we propose a high-altitude adjustable welding work platform for steel pipe concrete tied arches that can be widened to avoid the inconvenience caused by frequent platform movements and improve construction efficiency. Utility Model Content

[0005] The purpose of this utility model is to provide a high-altitude adjustable welding operation platform for steel pipe concrete tied arches, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-altitude adjustable welding operation platform for steel pipe concrete tie rod arches, comprising a mobile vehicle, a lifting mechanism above the mobile vehicle, a control panel fixedly installed on the outer wall of the mobile vehicle, and a processing component disposed outside the mobile vehicle, the processing component including a widening component disposed above the mobile vehicle, and a support component disposed below the widening component.

[0007] Preferably, the widening component includes a base plate fixedly installed on the top surface of the lifting mechanism, a limit plate slidably disposed inside the base plate, a widening plate fixedly installed on the side wall of the limit plate, a sleeve block fixedly installed on the outer wall of the limit plate, a counter-threaded rod sleeved inside the sleeve block, a fixing block rotatably connected to the outer wall of the counter-threaded rod, a long rail fixedly installed on the outer wall of the widening plate, a sliding rod fixedly installed on the outer wall of the long rail, and a short rail slidably disposed on the outer wall of the sliding rod.

[0008] Preferably, the support assembly includes a connecting plate hinged to the outer wall of the mobile vehicle, a sleeve slidably disposed on the outside of the connecting plate, a collar fixedly installed at the end of the sleeve, a screw sleeved inside the collar, a support plate rotatably connected to the end of the screw, a first magnetic block fixedly installed on the outer wall of the sleeve, a fixing plate disposed on the outside of the first magnetic block, and a second magnetic block fixedly installed on the outer wall of the fixing plate.

[0009] Preferably, the outer wall of the fixing block is fixedly installed to the outer wall of the base plate, and the outer wall of the opposing threaded rod is rotatably connected to the inside of the fixing block, so that the opposing threaded rod can rotate stably under the support and restriction of the fixing block.

[0010] Preferably, there are two widening plates, symmetrically distributed around the center line of the base plate, which can widen the standing platform under the constraint of the widening plates.

[0011] Preferably, there are two long railings, symmetrically distributed around the center line of the base plate. With the long railings and short railings working together, operators can be protected from falling.

[0012] Preferably, the outer wall of the widening plate is slidably disposed with the inside of the base plate, and the limiting plate is threadedly sleeved with the opposing threaded rod through a sleeve block. Under its restriction, the rotating opposing threaded rod can drive the limiting plate to move through the sleeve block to adjust the size of the standing platform.

[0013] Preferably, the first magnetic block and the second magnetic block are magnetically attracted to each other, and the fixing plate is fixedly installed on the outer wall of the mobile vehicle. Under its restriction, the moving plate of the mobile vehicle can be prevented from rotating arbitrarily.

[0014] Preferably, the bottom of the support plate is made of rubber, and there are four support plates in two groups, which are symmetrically distributed around the center line of the bottom of the mobile vehicle. Under the constraint of the rubber support plates, the support plates can be prevented from sliding with the ground.

[0015] Preferably, there are four connecting plates, divided into two groups, symmetrically distributed around the center line of the bottom of the mobile vehicle. Under the constraint of the four connecting plates, the mobile vehicle can be provided with auxiliary support, thereby improving the safety factor of the steel pipe concrete tied arch construction.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. This adjustable high-altitude welding work platform for steel-concrete tied arches consists of a widening component. During the construction of the steel-concrete tied arch, the work platform is used to move a mobile vehicle to the required position. The mobile vehicle is supported by a support component. The operator stands on the widening component and activates the lifting mechanism to raise the widening component for construction of the steel-concrete tied arch. When working on the adjacent external area of ​​the work platform, rotating the opposing threaded rod causes the limiting plate to slide within the base plate. Under its constraint, the rotating opposing threaded rod drives two sleeve blocks to move in opposite directions, causing the sleeve blocks to slide the limiting plate within the base plate and push the widening plate outwards. At this time, the widening plate moves the long railing accordingly. The sliding rod, fixedly installed on the outer wall of the long railing, slides within the short railing, widening the standing platform. The sliding rod protects the operator from falling. This structure widens the work platform, avoiding the inconvenience of frequent platform movements and improving construction efficiency.

[0018] 2. This adjustable high-altitude welding platform for steel-concrete composite tied arches consists of a support assembly. During the construction of the steel-concrete composite tied arch, the lifting mechanism and widening assembly assist in the operation. To ensure the stability of the mobile vehicle, lifting mechanism, and widening assembly, the connecting plate is rotated around its hinge point with the mobile vehicle. This pulls the sleeve, causing it to slide on the outer wall of the connecting plate. The screw is rotated to push the support plate towards the ground. When the support plate contacts the ground, the screw and sleeve work together to support the mobile vehicle. Under the sliding restriction of the connecting plate and sleeve, the support range can be adjusted according to the size of the site. After the construction of the steel-concrete composite tied arch is completed, the screw is reversed to slide the sleeve towards the mobile vehicle. The connecting plate is rotated so that the first magnetic block fixedly installed on the outer wall of the sleeve aligns with the second magnetic block fixedly installed on the outer wall of the fixed plate. Under the restriction of magnetic attraction, the connecting plate is prevented from shaking and deflecting when the mobile vehicle moves. This structure can stably support the mobile vehicle, thereby improving the safety factor of the steel-concrete composite tied arch construction. Attached Figure Description

[0026] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.

[0027] Example 1: A preferred embodiment of the adjustable high-altitude welding platform for steel-concrete composite tied arches provided by this utility model. Figures 1 to 6 As shown: A high-altitude adjustable welding operation platform for steel pipe concrete tied arch, including a mobile vehicle 1;

[0028] A lifting mechanism 2 is installed above the mobile vehicle 1;

[0029] A control panel 3 is fixedly installed on the outer wall of the mobile vehicle 1;

[0030] The processing component 4 is located outside the mobile vehicle 1. The processing component 4 includes a widening component 41 located above the mobile vehicle 1. The widening component 41 includes a base plate 411 fixedly installed on the top surface of the lifting mechanism 2. A limit plate 412 is slidably installed inside the base plate 411. A widening plate 413 is fixedly installed on the side wall of the limit plate 412. A sleeve block 414 is fixedly installed on the outer wall of the limit plate 412. A counter-threaded rod 415 is sleeved inside the sleeve block 414. A fixing block 416 is rotatably connected to the outer wall of the counter-threaded rod 415. A long railing 417 is fixedly installed on the outer wall of the widening plate 413. A sliding rod 418 is fixedly installed on the outer wall of the long railing 417. A short railing 419 is slidably installed on the outer wall of the sliding rod 418.

[0031] In this embodiment, during the construction of the steel-concrete tied arch, a working platform is needed to move the mobile vehicle 1 to the required position. The mobile vehicle 1 is supported by the support component 42. The operator stands on the widening component 41 and starts the lifting mechanism 2 to raise the widening component 41 to carry out the construction of the steel-concrete tied arch. When constructing the external area adjacent to the working platform, the opposing threaded rod 415 is rotated. Due to the sliding arrangement between the limiting plate 412 and the base plate 411, the rotating opposing threaded rod 415 is restricted. 5 drives the two sleeve blocks 414 to move in opposite directions, causing the sleeve blocks 414 to drive the limiting plate 412 to slide inside the base plate 411, and push the widening plate 413 to the outside of the base plate 411. At this time, the widening plate 413 drives the long railing 417 to move accordingly. The sliding rod 418 fixedly installed on the outer wall of the long railing 417 slides inside the short railing 419 to widen the standing platform. Under the protection of the sliding rod 418, the operator can be prevented from falling. This structure can widen the working platform, avoid the inconvenience caused by frequent platform movement, and improve construction efficiency.

[0032] The outer wall of the fixing block 416 is fixedly installed on the outer wall of the base plate 411, and the outer wall of the opposing threaded rod 415 is rotatably connected to the inside of the fixing block 416. Under the support and restriction of the fixing block 416, the opposing threaded rod 415 can rotate stably.

[0033] There are two widening plates 413, which are symmetrically distributed around the center line of the base plate 411. The standing platform can be widened by the restriction of the widening plates 413.

[0034] There are two long railings 417, which are symmetrically distributed along the center line of the base plate 411. With the cooperation of the long railings 417 and the short railings 419, the operators can be protected from falling.

[0035] The outer wall of the widening plate 413 is slidably disposed with the inside of the base plate 411. The limiting plate 412 is threadedly sleeved with the opposing threaded rod 415 through the sleeve block 414. Under its restriction, the rotating opposing threaded rod 415 can drive the limiting plate 412 to move through the sleeve block 414 to adjust the size of the standing platform.

[0036] Example 2: Based on Example 1, a preferred embodiment of the adjustable high-altitude welding platform for steel-concrete composite tie-arches provided by this utility model is as follows: Figures 1 to 6 As shown: The support assembly 42 includes a connecting plate 421 hinged to the outer wall of the mobile vehicle 1. A sleeve 422 is slidably disposed on the outside of the connecting plate 421. A collar 423 is fixedly installed at the end of the sleeve 422. A screw 424 is sleeved inside the collar 423. A support plate 425 is rotatably connected to the end of the screw 424. A first magnetic block 426 is fixedly installed on the outer wall of the sleeve 422. A fixing plate 427 is disposed on the outside of the first magnetic block 426. A second magnetic block 428 is fixedly installed on the outer wall of the fixing plate 427.

[0037] In this embodiment, during the construction of the steel-concrete composite tie-arch, the lifting mechanism 2 and the widening component 41 assist in the operation. To ensure the stable operation of the mobile vehicle 1, the lifting mechanism 2, and the widening component 41, the connecting plate 421 is rotated around its hinge point with the mobile vehicle 1 as the center of rotation. The sleeve 422 is pulled, causing it to slide on the outer wall of the connecting plate 421. The screw 424 is rotated, pushing the support plate 425 towards the ground. When the support plate 425 contacts the ground, the screw 424 and the sleeve 422 work together to support the mobile vehicle 1. Under the sliding restriction of sleeve 422, the support range can be adjusted according to the size of the site. After the construction of the steel pipe concrete tied arch is completed, reverse screw 424 to slide sleeve 422 towards the moving vehicle 1, rotate connecting plate 421 to align the first magnetic block 426 fixedly installed on the outer wall of sleeve 422 with the second magnetic block 428 fixedly installed on the outer wall of fixing plate 427. Under the restriction of magnetic attraction, the connecting plate 421 is prevented from shaking and deflecting when the moving vehicle 1 moves. This structure can stably support the moving vehicle 1 to improve the safety factor of steel pipe concrete tied arch construction.

[0038] Among them, the first magnetic block 426 and the second magnetic block 428 are magnetically attracted to each other, and the fixed plate 427 is fixedly installed on the outer wall of the mobile vehicle 1. Under its restriction, the moving connecting plate 421 of the mobile vehicle 1 can be prevented from rotating at will.

[0039] Among them, the bottom of the support plate 425 is made of rubber. There are four support plates 425, which are divided into two groups and symmetrically distributed around the center line of the bottom of the mobile vehicle 1. Under the constraint of the rubber support plates 425, the support plates 425 can be prevented from sliding with the ground.

[0040] There are four connecting plates 421, which are divided into two groups and symmetrically distributed around the bottom center line of the mobile vehicle 1. Under the constraint of the four connecting plates 421, the mobile vehicle 1 can be provided with auxiliary support, thereby improving the safety factor of the steel pipe concrete tied arch construction.

Any equivalent changes and modifications made by those skilled in the art without departing from the concept and principles of this utility model should fall within the protection scope of this utility model. Furthermore, it should be noted that the components of this utility model are not limited to the overall application described above. Each technical feature described in the specification can be used individually or in combination as needed. Therefore, this utility model naturally covers other combinations and specific applications related to the points of this utility model.
