Description

Technical Field

[0001] The invention relates to the technical field of hanging ladder production, in particular to a hanging ladder quick assembly tool. Background Art

[0002] The hanging ladder is a common climbing tool, widely used in construction, power maintenance, shipbuilding and other fields. In the production process of hanging ladders, the assembly process is relatively complicated. The hanging ladders are mainly composed of ladder frames, steps and other components. The traditional hanging ladder assembly method mostly relies on manual operation. Each component is manually positioned and aligned, and then assembled by positioning welding. This assembly method has many problems. On the one hand, the manual operation efficiency is low and the assembly speed is slow, which is difficult to meet the needs of large-scale production; on the other hand, the accuracy of manual assembly is difficult to guarantee, and it is easy to have component assembly dislocation and loose connection, which affects the overall quality and safety of the hanging ladder. It is necessary to work hard on production efficiency. The key point affecting the entire production cycle is analyzed in the assembly process. If the speed can be improved in the assembly process, whether it is to complete the task on schedule or reduce labor costs and improve work efficiency, a breakthrough will be achieved, and efficiency will be improved. After analysis, it can be found that for some hanging ladders, such as hanging ladders with a length of 2 meters and 2.4 meters, both types of hanging ladders are made of steel pipes with a diameter of 27mm. Except for the difference in length, the other dimensions of the ladders are the same. Therefore, a quick assembly tool can be designed to achieve quick assembly of these two types of hanging ladders. Summary of the invention

And because the inner diameter of the upper card slot is large and the inner diameter of the lower card slot is small, during use, it can ensure that the thinner ladder frame enters the corresponding card slot. Different arc-shaped clamping seats are used to clamp ladder steps of different thicknesses, and because the centers of the inner diameters of different arc-shaped clamping seats are different from the center of the mounting disk, they are used to match the card slots at different heights, ensuring that after the ladder frame is clamped into one of the card slots, the ladder step can also be clamped into the arc-shaped clamping seat at the corresponding height. Just switch the corresponding arc-shaped clamping seat by rotating the first rotating shaft before clamping; When placing the ladder frame, the left end of the ladder frame needs to be abutted against the right outer wall of the equalizing plate.

During assembly, only the ladder frame 5 and the ladder step 6 need to be placed properly, there is no need to mark the parts that need to be welded on the ladder frame 5, and there is no need for workers to hold the ladder frame 5 and the ladder step 6 while welding, which improves the welding efficiency and reduces the welding time, and can effectively improve the assembly efficiency. The positioning component 8 is set to position the ladder frame 5, that is, to position one end of the ladder frame 5 to ensure that the two ladder frames 5 will not be misaligned during welding; The auxiliary support 7 includes a fixed frame 701 which is fixedly installed on the top of the bottom plate 1. A first rotating shaft 702 is rotatably connected to the inner side of the fixed frame 701 through a bearing. A plurality of first rotating shafts 702 in the fixed frame 701 are arranged at equal intervals. An installation disk 703 is fixedly installed on the outer wall of the first rotating shaft 702, and two installation disks 703 are symmetrically arranged on the same first rotating shaft 702.

By rotating the first rotating shaft 702 through the rotating component 705, the installation disk 703 is driven to rotate. When the installation disk 703 rotates, the arc-shaped clamping seat 704 on it rotates to be parallel to the main support 3, so that when the ladder frame 5 is placed into the clamping groove 301, the arc-shaped clamping seat 704 can support the step 6, and at this time the step 6 is flush with the ladder frame 5, and there is no need to adjust the height of the step 6 during welding.

It only needs to switch the corresponding arc-shaped clamping seat 704 by rotating the first rotating shaft 702 before clamping; The rotating component 705 includes a second rotating shaft 7053. The left and right ends of the second rotating shaft 7053 are rotatably connected to the inner wall of the fixed frame 701 through bearings.

The worm gear 7052 is fixedly installed on the first rotating shaft 702. By rotating the second rotating shaft 7053, all the worms 7051 are driven to rotate, and then all the worm gears 7052 on the first rotating shafts 702 are driven to rotate simultaneously, realizing synchronous adjustment. There is no need to adjust each first rotating shaft 702 one by one, reducing the adjustment steps and shortening the adjustment time. The spacing adjustment component 4 includes a T-shaped sliding rail 401, positioning holes 402, and fixing bolts 403. The T-shaped sliding rail 401 is fixedly installed on the top of the bottom plate 1. The mounting frame 2 is slidably arranged on the T-shaped sliding rail 401. The positioning holes 402 are opened on the top of the bottom plate 1, and there are two rows of positioning holes 402. The mounting frame 2 is connected to the positioning holes 402 through the fixing bolts 403.

And the positioning holes 402 with multiple fixed spacings can adjust the mounting frame 2 step by step, and then the mounting frame 2 can be fixed through the fixing bolts 403. The worm 7051 and the worm gear 7052 are covered with a protective cover 13. The left and right ends of the second rotating shaft 7053 extend out of the fixed frame 701, and rotating handles 14 are fixedly installed at the left and right ends of the second rotating shaft 7053.

[0019] Working principle: When in use, according to the size of a batch of hanging ladders to be assembled, the spacing of the mounting frame 2 is adjusted. After the adjustment is completed, the mounting frame 2 is fixed with the fixing bolts 403. Then, the second rotating shaft 7053 is rotated to drive the worm 7051 to rotate, and then drive the worm gear 7052 to rotate, so that the worm gear 7052 drives the first rotating shaft 702 to rotate. The rotation of the first rotating shaft 702 drives the mounting disc 703 to rotate, so that an arc-shaped clamping seat 704 on the mounting disc 703 is parallel to the main support 3, and the inner diameter of the arc-shaped clamping seat 704 corresponds to the ladder step 6 of the hanging ladder. The ladder frame 5 is placed into the card slot 301, and then the ladder step 6 is placed into the arc-shaped clamping seat 704, and the positioning welding is performed on the contact parts of the ladder frame 5 and the ladder step 6, and then the rapid assembly of the hanging ladder can be completed.

The ladder frame 5 is clamped and positioned by the main support 3, and then the ladder steps 6 are clamped and positioned by the secondary support 7. During assembly, only the ladder frame 5 and the ladder steps 6 need to be placed properly, without marking the welding parts on the ladder frame 5, and without the worker holding the ladder frame 5 and the ladder steps 6 while welding, which improves the welding efficiency and reduces the welding time, and can effectively improve the assembly efficiency. The positioning component 8 is set to position the ladder frame 5, that is, to position one end of the ladder frame 5, ensuring that the two ladder frames 5 will not be misaligned during welding; The secondary support 7 includes a fixed frame 701. The fixed frame 701 is fixedly installed on the top of the bottom plate 1. A rotating shaft one 702 is rotatably connected to the inner side of the fixed frame 701 through a bearing.

And two installation disks 703 are arranged on the same rotating shaft one 702, which are used to set two groups of arc-shaped clamping seats 704 to support and position the same ladder step 6, ensuring the stability of the support for the ladder step 6; There are multiple card slots 301 on the main bracket 3, and the multiple card slots 301 communicate with each other. The card slots 301 are distributed from top to bottom, and their inner diameters gradually decrease from top to bottom. The card slots 301 with gradually decreasing inner diameters are used to hold ladder frames 5 of different thicknesses, further improving the scope of use of this tooling. And because the inner diameter of the upper card slot 301 is large and the inner diameter of the lower card slot 301 is small, when in use, it can ensure that the thinner ladder frame 5 enters the corresponding card slot 301; There are four arc-shaped clamping seats 704 on the mounting disc 703, and the four arc-shaped clamping seats 704 are circumferentially arrayed on the mounting disc 703.

Different arc-shaped clamping seats 704 are used to hold ladder steps 6 of different thicknesses. And because the centers of the inner diameters of different arc-shaped clamping seats 704 and the center of the mounting disc 703 are different, they are used to match the card slots 301 at different heights, ensuring that after the ladder frame 5 is inserted into one of the card slots 301, the ladder step 6 can also be inserted into the corresponding arc-shaped clamping seat 704 at the corresponding height. Just switch the corresponding arc-shaped clamping seat 704 by rotating the rotating shaft one 702 before insertion; The rotating component 705 includes a rotating shaft two 7053.
