Abstract
Description
Technical Field
[0001] This utility model relates to the field of ladder processing technology, and in particular to a ladder splicing device. Background Technology
[0002] The ladder structure includes multiple horizontal ribs and two vertical ribs, both of which are L-shaped. The two vertical ribs are positioned with their inner right angles facing each other. The ends of the horizontal ribs are welded to the corresponding inner right angles of the vertical ribs. Current technology for manufacturing this ladder involves: manually placing the two vertical ribs on the ground and using weights to hold them down and prevent movement; then manually measuring and determining the placement of the horizontal ribs; and finally, manually pressing down on the horizontal ribs with one hand while using welding equipment to weld their ends. This method has the following problems: The placement of the two vertical ribs requires multiple adjustments based on the width of the horizontal ribs; using weights to fix the vertical ribs requires manual labor for moving or removing the weights, making operation inconvenient; manually measuring to determine the position of the horizontal ribs is inefficient and inaccurate; and there is a risk of the horizontal ribs shifting during welding. Utility Model Content
[0003] To address the shortcomings of existing technologies, this utility model provides a ladder splicing device that can quickly and accurately complete the splicing of horizontal and vertical ribs.
[0004] In order to achieve the purpose of this utility model, the following solution is proposed:
[0005] A ladder assembly device, wherein the ladder includes multiple horizontal ribs and two vertical ribs, and the device includes multiple bases, a limiting mechanism, and a first platform and a second platform arranged in parallel.
[0006] The top of the first platform is provided with a strip groove for placing one of the longitudinal reinforcement bars;
[0007] The top of the second platform is equipped with a groove for placing another longitudinal reinforcement.
[0008] Multiple support seats are arrayed between the first platform and the second platform. Multiple bases are arrayed on the top of the corresponding support seats. A baffle is provided on the top of the base. The right angle formed by the base and the baffle is used to match the outer right angle of the transverse rib. Two protruding plates are provided on one side of the base. The top surface of the protruding plates is flush with the top surface of the base.
[0009] The limiting mechanism includes a first telescopic rod, a guide rod, and multiple L-shaped limiting plates. The guide rod horizontally passes through all the support seats. The longitudinal section of the L-shaped limiting plate is fixedly connected to the guide rod. One L-shaped limiting plate corresponds to one base, and the longitudinal section of the L-shaped limiting plate is slidably fitted between two protruding plates. The transverse section of the L-shaped limiting plate is used to limit the inner right angle of the transverse rib. The first telescopic rod is located on the first platform or the second platform, and its movable end is connected to the guide rod through a bracket for moving the position of the guide rod.
[0010] Furthermore, it also includes an assembly mechanism, which includes a second telescopic rod and a push plate. The outer side of the chute passes through the second platform. The second telescopic rod is located on the second platform, and its movable end is connected to the push plate. The push plate is located inside the chute and is used to push the longitudinal ribs inside the chute toward the first platform.
[0011] Furthermore, the thickness of the transverse section of the longitudinal reinforcement is consistent with the depth of the strip groove and also with the depth of the sliding groove. When the transverse reinforcement is placed on the base, the bottom surface of the transverse reinforcement is in close contact with the top surface of the first platform and the top surface of the second platform.
[0012] Furthermore, the length of the longitudinal reinforcement is the same as the length of the strip groove, and the width of the transverse section of the longitudinal reinforcement is greater than the width of the strip groove.
[0013] The beneficial effects of this utility model are as follows: the positions of two longitudinal ribs can be determined by the strip groove and the slide groove; the positions of multiple transverse ribs can be determined by the base arranged in multiple arrays, and the spacing between any two adjacent transverse ribs is consistent; the limiting mechanism can restrict the position of all transverse ribs to prevent them from moving randomly during the welding process. After welding is completed, the limiting mechanism can release all transverse ribs at the same time so that the ladder can be taken out. Attached Figure Description

[0020] An existing ladder structure includes multiple horizontal ribs and two vertical ribs, both of which are L-shaped. Before starting the welding process, to more quickly and accurately complete the splicing of the horizontal and vertical ribs, such as... Figure 1 , Figure 3 As shown, this embodiment provides a ladder splicing device, including multiple bases 3, a limiting mechanism 4, a first platform 1, and a second platform 2.
[0021] Specifically, the first platform 1 and the second platform 2 are set in parallel, and their surfaces are flush.
[0022] Specifically, the top of the first platform 1 is provided with a strip groove 11, the long axis of the strip groove 11 is consistent with the long axis of the first platform 1, the strip groove 11 is used to place one of the longitudinal ribs, and the transverse section of the longitudinal rib is located in the strip groove 11. The thickness of the transverse section of the longitudinal rib is consistent with the depth of the strip groove 11, that is, the top surface of the transverse section of the longitudinal rib is flush with the surface of the first platform 1.
[0023] Specifically, the top of the second platform 2 is provided with a groove 21, the long axis of the groove 21 is consistent with the long axis of the second platform 2, the groove 21 is used to place another longitudinal rib, and the transverse section of the longitudinal rib is located in the groove 21. The thickness of the transverse section of the longitudinal rib is consistent with the depth of the groove 21, that is, the top surface of the transverse section of the longitudinal rib is flush with the surface of the second platform 2.
[0024] Specifically, such as Figure 3 , Figure 5 As shown, multiple support seats 6 are arrayed between the first platform 1 and the second platform 2, and multiple bases 3 are arrayed on the top of the corresponding support seats 6. The top of the base 3 is provided with a baffle 31. The right angle formed by the base 3 and the baffle 31 is used to match the outer right angle of the horizontal rib. When the horizontal rib is placed on the base 3, the bottom surface of the horizontal rib is in close contact with the top surface of the first platform 1 and the top surface of the second platform 2. Two protruding plates 32 are provided on one side of the base 3, and the top surface of the protruding plate 32 is flush with the top surface of the base 3. The axis of symmetry of the two protruding plates 32 is consistent with the direction of the long axis of the second platform 2.
[0025] Specifically, such as Figure 1 , Figure 2 , Figure 4 , Figure 5 As shown, the limiting mechanism 4 includes a first telescopic rod 41, a guide rod 42, and multiple L-shaped limiting plates 43. The guide rod 42 horizontally penetrates all support seats 6. The longitudinal section of the L-shaped limiting plate 43 is fixedly connected to the guide rod 42. One L-shaped limiting plate 43 corresponds to one base 3, and the longitudinal section of the L-shaped limiting plate 43 is slidably engaged between two protruding plates 32. The transverse section of the L-shaped limiting plate 43 is used to limit the inner right angle of the transverse rib. The first telescopic rod 41 is located on the first platform 1 or the second platform 2. In this embodiment, the first telescopic rod 41 is located on the second platform 2. The power source of the first telescopic rod 41 can be a cylinder or a hydraulic cylinder. Its movable end is connected to the guide rod 42 through a bracket 45. The first telescopic rod 41 is used to move the position of the guide rod 42, thereby moving the position of all L-shaped limiting plates 43 to achieve the limiting or release of the transverse rib.
[0026] The above method is as follows: First, use the first telescopic rod 41 to move all L-shaped limiting plates 43 away from the corresponding baffles 31, exposing the space at the top of the base 3 to facilitate the subsequent placement of horizontal ribs; place the two longitudinal ribs in the strip groove 11 and the slide groove 21 respectively; place multiple horizontal ribs on the corresponding base 3 in sequence; use the first telescopic rod 41 to move all L-shaped limiting plates 43 towards the baffles 31 until the horizontal section of the L-shaped limiting plate 43 restricts the inner right angle of the horizontal ribs; after the ladder is assembled, use automated welding equipment to automatically weld the ends of the horizontal ribs to the longitudinal ribs, or use manual hand-held welding equipment for welding; after welding is completed, use the first telescopic rod 41 to move the position of all L-shaped limiting plates 43 to release the horizontal ribs from the L-shaped limiting plates 43 so that the ladder can be removed.
[0027] In the above scheme, two longitudinal bars are placed first, followed by multiple transverse bars. To further optimize this, this embodiment provides another scheme, the specific implementation of which is as follows:
[0028] like Figure 6 As shown, the device also includes an assembly mechanism 5, which includes a second telescopic rod 51 and a push plate 52. The outer side of the slide groove 21 passes through the second platform 2. The second telescopic rod 51 is located on the second platform 2. The power source of the second telescopic rod 51 can be a cylinder or a hydraulic cylinder. Its movable end is connected to the push plate 52. The push plate 52 is located in the slide groove 21. The second telescopic rod 51 is used to move the position of the push plate 52. The push plate 52 is used to push the longitudinal ribs in the slide groove 21 toward the first platform 1.
[0029] like Figure 2 , Figure 6 As shown, the length of the longitudinal reinforcement is the same as the length of the strip groove 11, and the width of the transverse section of the longitudinal reinforcement is greater than the width of the strip groove 11.
[0030] Instructions for use: First, use the first telescopic rod 41 to move all L-shaped limiting plates 43 away from their corresponding baffles 31, exposing the space at the top of the base 3 to facilitate the subsequent placement of transverse ribs; second, use the second telescopic rod 51 to move the push plate 52 further away from the first platform 1; place the two longitudinal ribs in the strip groove 11 and the slide groove 21 respectively. Note that in this step, the longitudinal ribs in the slide groove 21 do not need to be placed in a specific position, and the distance between the two longitudinal ribs is greater than the length of the transverse ribs. This design is intended to facilitate the placement of transverse ribs; place the multiple transverse ribs sequentially... Place it on the corresponding base 3; use the first telescopic rod 41 to move all L-shaped limiting plates 43, so that the L-shaped limiting plates 43 move towards the baffle 31 until the horizontal section of the L-shaped limiting plate 43 restricts the inner right angle of the horizontal rib. Note that the L-shaped limiting plate 43 does not clamp the inner right angle of the horizontal rib, but only needs to be close to the inner right angle of the horizontal rib, so that the horizontal rib can still move along its own length direction; use the second telescopic rod 51 to move the push plate 52, so that the push plate 52 moves towards the first platform 1. During this process, the push plate 52 will make fine adjustments to the positions of the two longitudinal ribs and multiple horizontal ribs until the splicing of the ladder is completed.
[0031] The above embodiments are only used to illustrate the technical concept and features of this utility model, and are not intended to be unique or to limit this utility model. Those skilled in the art should understand that various changes or equivalent substitutions made to this utility model without departing from its scope are all within the protection scope of this utility model.
