Description

Technical Field

[0001] This utility model relates to the field of ladder manufacturing technology, specifically a quick assembly tooling for ladders. Background Technology

[0002] A hanging ladder is a common tool for climbing, widely used in fields such as building construction, power maintenance, and shipbuilding. The assembly process in the production of hanging ladders is quite complex. Hanging ladders are mainly composed of components such as ladder frames and steps. Traditional hanging ladder assembly methods mostly rely on manual operation, where various components are manually positioned and aligned, and then assembled using tack welding. This assembly method has many problems. On the one hand, manual operation is inefficient and slow, making it difficult to meet the needs of large-scale production. On the other hand, the precision of manual assembly is difficult to guarantee, easily leading to misalignment of components and weak connections, affecting the overall quality and safety of the hanging ladder. It is necessary to focus on production efficiency. Analysis shows that the key point affecting the entire production cycle is the assembly process. If the speed of the assembly process can be improved, breakthroughs will be achieved in both completing tasks on time and reducing labor costs and improving work efficiency, thus improving efficiency. Analysis shows that for some hanging ladders, such as those with lengths of 2 meters and 2.4 meters, both types of hanging ladders are made using steel pipes with a diameter of 27mm. Except for the length, the dimensions of the ladders are the same. Therefore, a rapid assembly fixture can be designed to achieve rapid assembly of these two types of hanging ladders. Utility Model Content

[0003] The purpose of this utility model is to provide a quick assembly tool for hanging ladders to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a quick assembly fixture for a hanging ladder, comprising a base plate, a mounting frame on the top of the base plate, the mounting frame being slidably mounted on the base plate via a spacing adjustment component, the mounting frame being arranged in two rows, a main support being fixedly mounted on the top of the mounting frame, multiple main supports being evenly spaced on the mounting frame, a slot being provided on the main support, and the ladder frame being secured in the slot, a secondary support being provided on the top of the base plate, and the ladder steps being placed in the slots of the secondary support, and a positioning component being fixedly mounted on the left end of the base plate.

[0005] Furthermore, the auxiliary support includes a fixed frame, which is fixedly installed on the top of the base plate. A rotating shaft is rotatably connected to the inner side of the fixed frame via a bearing. Multiple rotating shafts are equally spaced within the fixed frame. An mounting plate is fixedly installed on the outer wall of each rotating shaft, and two mounting plates are symmetrically arranged on the same rotating shaft. An arc-shaped bracket is fixedly installed on the mounting plate. The step is placed inside the arc-shaped bracket. A rotating component is provided inside the fixed frame, and the rotating component is connected to the rotating shaft via a transmission.

[0006] Furthermore, the main support has multiple slots that are interconnected, and the slots are distributed from top to bottom, with their inner diameter decreasing progressively from top to bottom.

[0007] Furthermore, the mounting plate has four arc-shaped card holders, which are arranged in a circumferential array on the mounting plate. The inner diameters of the four arc-shaped card holders are different, and the distance between the center of the inner diameter of the four arc-shaped card holders and the center of the mounting plate is different.

[0008] Furthermore, the rotating component includes a second rotating shaft, the left and right ends of which are rotatably connected to the inner wall of the fixed frame via bearings. A worm is fixedly installed on the outer wall of the second rotating shaft, the worm meshing with a worm wheel, and the worm wheel is fixedly installed on the first rotating shaft.

[0009] Furthermore, the spacing adjustment component includes a T-shaped slide rail, positioning holes, and fixing bolts. The T-shaped slide rail is fixedly installed on the top of the base plate, and the mounting bracket is slidably mounted on the T-shaped slide rail. The positioning holes are opened on the top of the base plate, and there are two rows of positioning holes. The mounting bracket is connected to the positioning holes by fixing bolts.

[0010] Furthermore, the worm gear and worm wheel are covered with protective covers, and the left and right ends of the second rotating shaft extend from the fixed frame, with a throttle handle fixedly installed at the left and right ends of the second rotating shaft.

[0011] Furthermore, the positioning component includes an equipotential plate, which is fixedly installed on the left end of the base plate. A positioning bracket is fixedly installed on the right outer wall of the equipotential plate, and the left end of the ladder passes through the positioning bracket and abuts against the right outer wall of the equipotential plate.

[0012] Furthermore, the positioning card holder has a positioning groove corresponding to the card slot, and the positioning card holder is made of elastic material.

[0013] Furthermore, a track frame is fixedly installed at the bottom of the base plate, rollers are installed inside the track frame, a reinforcing plate is fixedly installed at the bottom of the base plate, and a fixing pin is inserted into the positioning hole.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] The spacing between the two mounting brackets is adjusted by the spacing adjustment component to accommodate different lengths of ladder steps. The main bracket clamps and positions the ladder frame, and the secondary bracket clamps and positions the ladder steps. During assembly, only the ladder frame and ladder steps need to be placed. There is no need to mark the parts to be welded on the ladder frame, and workers do not need to hold the ladder frame and ladder steps while welding, which improves welding efficiency and reduces welding time. It can effectively improve assembly efficiency. The positioning component is set to position the ladder frame, that is, to position one end of the ladder frame, to ensure that the two ladder frames will not be misaligned during welding.

[0016] Rotating the rotating component rotates the first rotating shaft, which in turn drives the mounting plate to rotate. The rotating mounting plate rotates the arc-shaped bracket on it to be parallel to the main bracket, so that when the ladder frame is placed in the slot, the arc-shaped bracket can support the ladder step. At this time, the ladder step is flush with the ladder frame, and there is no need to adjust the height of the ladder step during welding. The spacing between adjacent rotating shafts is the same as the spacing between adjacent ladder steps, so there is no need to adjust the horizontal position of the ladder step during welding. There are two mounting plates on the same rotating shaft, which are used to set two sets of arc-shaped brackets to support and position the same ladder step, ensuring the stability of the ladder step support.

[0017] The tool is equipped with slots with progressively smaller inner diameters to hold ladders of different thicknesses, further expanding its versatility. Because the upper slot has a larger inner diameter and the lower slot has a smaller inner diameter, it ensures that thinner ladders can be inserted into the corresponding slots. Different curved brackets are used to hold ladder steps of different thicknesses. Since the center of the inner diameter of each curved bracket is different from the center of the mounting plate, they are used to match the slots at different heights. This ensures that after the ladder is inserted into one slot, the ladder steps can also be inserted into the curved bracket of the corresponding height. Simply rotate the shaft to switch to the corresponding curved bracket before inserting the ladder.

[0018] When placing the ladder rack, the left end of the ladder rack needs to be placed against the right outer wall of the equidistant plate. At this time, the positioning bracket positions and locks the end of the ladder rack, thereby ensuring that the two ladder racks are parallel and aligned left and right. The positioning bracket has a positioning groove corresponding to the slot, and the positioning bracket is made of elastic material, which allows the positioning bracket to lock ladder racks of different thicknesses. The elastic material of the positioning bracket can better lock the ladder rack. Attached Figure Description

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0031] Example 1

[0032] Please see Figures 1-10This utility model provides a technical solution: a quick assembly fixture for a hanging ladder, including a base plate 1, a mounting frame 2 on the top of the base plate 1, the mounting frame 2 being slidably mounted on the base plate 1 via a spacing adjustment component 4, the mounting frame 2 having two rows, a main support 3 being fixedly mounted on the top of the mounting frame 2, multiple main supports 3 being evenly spaced on the mounting frame 2, the main supports 3 having slots 301, and the ladder frame 5 being secured in the slots 301, a secondary support 7 being provided on the top of the base plate 1, and the ladder steps 6 being placed in the slots of the secondary support 7, a positioning component 8 being fixedly mounted on the left end of the base plate 1, and the positioning component 4 being adjusted via a spacing adjustment component 4. The spacing between the two mounting brackets 2 is adjusted to accommodate different lengths of ladder steps 6. The main bracket 3 is used to snap and position the ladder frame 5, and then the auxiliary bracket 7 is used to snap and position the ladder steps 6. During assembly, it is only necessary to place the ladder frame 5 and the ladder steps 6 in place. There is no need to mark the parts to be welded on the ladder frame 5, and workers do not need to hold the ladder frame 5 and the ladder steps 6 while welding. This improves welding efficiency and reduces welding time, effectively improving 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.

[0033] The auxiliary support 7 includes a fixed frame 701, which is fixedly installed on the top of the base plate 1. A rotating shaft 702 is rotatably connected to the inner side of the fixed frame 701 via bearings. Multiple rotating shafts 702 are evenly spaced within the fixed frame 701. A mounting plate 703 is fixedly installed on the outer wall of each rotating shaft 702, with two mounting plates 703 symmetrically arranged on the same rotating shaft 702. An arc-shaped bracket 704 is fixedly installed on each mounting plate 703. The step 6 is placed inside the arc-shaped bracket 704. A rotating component 705 is provided inside the fixed frame 701, and the rotating component 705 is connected to the rotating shaft 702 via a transmission connection, allowing the rotating shaft 702 to rotate. This causes the mounting plate 703 to rotate, and the rotation of the mounting plate 703 rotates the arc-shaped bracket 704 on it to be parallel to the main bracket 3. This allows the arc-shaped bracket 704 to support the step 6 when the ladder frame 5 is placed in the slot 301. At this time, the step 6 is flush with the ladder frame 5, so there is no need to adjust the height of the step 6 during welding. The spacing between adjacent rotating shafts 702 is the same as the spacing between adjacent steps 6, so there is no need to adjust the horizontal position of the step 6 during welding. In addition, there are two mounting plates 703 on the same rotating shaft 702, which are used to set two sets of arc-shaped brackets 704 to support and position the same step 6, ensuring the stability of the support for the step 6.

[0034] The main support 3 has multiple slots 301, which are interconnected. The slots 301 are distributed from top to bottom, and their inner diameters gradually decrease from top to bottom. The slots 301 with gradually decreasing inner diameters are used to hold ladder frames 5 of different thicknesses, which further improves the application range of the tooling. Because the inner diameter of the upper slot 301 is larger and the inner diameter of the lower slot 301 is smaller, it can ensure that the thinner ladder frame 5 can enter the corresponding slot 301 during use.

[0035] There are four arc-shaped brackets 704 on the mounting plate 703, and the four arc-shaped brackets 704 are arranged in a circumferential array on the mounting plate 703. The inner diameters of the four arc-shaped brackets 704 are different, and the distance between the center of the inner diameter of the four arc-shaped brackets 704 and the center of the mounting plate 703 is different. Different arc-shaped brackets 704 are used to hold ladder steps 6 of different thicknesses. Because the center of the inner diameter of different arc-shaped brackets 704 is different from the center of the mounting plate 703, they are used to match the slots 301 at different heights. This ensures that after the ladder frame 5 is inserted into one of the slots 301, the ladder step 6 can also be inserted into the arc-shaped bracket 704 of the corresponding height. Before insertion, the corresponding arc-shaped bracket 704 can be switched by rotating the pivot 702.

[0036] 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. A worm gear 7051 is fixedly installed on the outer wall of the second rotating shaft 7053. The worm gear 7051 meshes with a worm wheel 7052. The worm wheel 7052 is fixedly installed on the first rotating shaft 702. By rotating the second rotating shaft 7053, all the worm gears 7051 are driven to rotate, which in turn drives all the worm wheels 7052 on the first rotating shaft 702 to rotate simultaneously, realizing synchronous adjustment. It is not necessary to adjust each individual first rotating shaft 702 one by one, reducing adjustment steps and reducing adjustment time.

[0037] The spacing adjustment component 4 includes a T-shaped slide rail 401, positioning holes 402, and fixing bolts 403. The T-shaped slide rail 401 is fixedly installed on the top of the base plate 1, and the mounting bracket 2 is slidably mounted on the T-shaped slide rail 401. The positioning holes 402 are opened on the top of the base plate 1, and there are two rows of positioning holes 402. The mounting bracket 2 is connected to the positioning holes 402 by fixing bolts 403. By sliding the mounting bracket 2 along the T-shaped slide rail 401, the spacing between the two mounting brackets 2 is adjusted, thereby adjusting the spacing between the two ladder frames 5 so that their spacing matches the length of the ladder step 6. The multiple fixed spacing positioning holes 402 can adjust the mounting bracket 2 step by step. Then, the mounting bracket 2 is fixed by fixing bolts 403.

[0038] The worm gear 7051 and worm wheel 7052 are covered with protective covers 13. The left and right ends of the rotating shaft 7053 extend from the fixed frame 701, and the left and right ends of the rotating shaft 7053 are fixedly installed with handles 14. The protective covers 13 are provided to protect the worm gear 7051 and worm wheel 7052 to prevent heavy objects from falling on the worm gear 7051 and worm wheel 7052 during assembly. The handles 14 are provided to rotate the rotating shaft 7053, and there are handles 14 on both the left and right ends of the rotating shaft 7053, so that it can be rotated in any direction.

[0039] Working principle: When in use, adjust the spacing of the mounting frame 2 according to the size of the batch of hanging ladders to be assembled. After the adjustment is completed, use the fixing bolts 403 to fix the mounting frame 2. Then, rotate the second rotating shaft 7053 to drive the worm gear 7051 to rotate, which in turn drives the worm wheel 7052 to rotate. The worm wheel 7052 drives the first rotating shaft 702 to rotate. The rotation of the first rotating shaft 702 drives the mounting plate 703 to rotate, so that an arc-shaped bracket 704 on the mounting plate 703 is parallel to the main bracket 3, and the inner diameter of the arc-shaped bracket 704 corresponds to the step 6 of the hanging ladder. Place the ladder frame 5 into the slot 301, and then place the step 6 into the arc-shaped bracket 704. Perform positioning welding on the contact parts of the ladder frame 5 and the step 6 to complete the rapid assembly of the hanging ladder.

[0040] Example 2

[0041] Please see Figures 1-10 This utility model provides a technical solution: a quick assembly fixture for a hanging ladder, including a base plate 1, a mounting frame 2 on the top of the base plate 1, the mounting frame 2 being slidably mounted on the base plate 1 via a spacing adjustment component 4, the mounting frame 2 having two rows, a main support 3 being fixedly mounted on the top of the mounting frame 2, multiple main supports 3 being evenly spaced on the mounting frame 2, the main supports 3 having slots 301, and the ladder frame 5 being secured in the slots 301, a secondary support 7 being provided on the top of the base plate 1, and the ladder steps 6 being placed in the slots of the secondary support 7, a positioning component 8 being fixedly mounted on the left end of the base plate 1, and the positioning component 4 being adjusted via a spacing adjustment component 4. The spacing between the two mounting brackets 2 is adjusted to accommodate different lengths of ladder steps 6. The main bracket 3 is used to snap and position the ladder frame 5, and then the auxiliary bracket 7 is used to snap and position the ladder steps 6. During assembly, it is only necessary to place the ladder frame 5 and the ladder steps 6 in place. There is no need to mark the parts to be welded on the ladder frame 5, and workers do not need to hold the ladder frame 5 and the ladder steps 6 while welding. This improves welding efficiency and reduces welding time, effectively improving 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.

[0042] The auxiliary support 7 includes a fixed frame 701, which is fixedly installed on the top of the base plate 1. A rotating shaft 702 is rotatably connected to the inner side of the fixed frame 701 via bearings. Multiple rotating shafts 702 are evenly spaced within the fixed frame 701. A mounting plate 703 is fixedly installed on the outer wall of each rotating shaft 702, with two mounting plates 703 symmetrically arranged on the same rotating shaft 702. An arc-shaped bracket 704 is fixedly installed on each mounting plate 703. The step 6 is placed inside the arc-shaped bracket 704. A rotating component 705 is provided inside the fixed frame 701, and the rotating component 705 is connected to the rotating shaft 702 via a transmission connection, allowing the rotating shaft 702 to rotate. This causes the mounting plate 703 to rotate, and the rotation of the mounting plate 703 rotates the arc-shaped bracket 704 on it to be parallel to the main bracket 3. This allows the arc-shaped bracket 704 to support the step 6 when the ladder frame 5 is placed in the slot 301. At this time, the step 6 is flush with the ladder frame 5, so there is no need to adjust the height of the step 6 during welding. The spacing between adjacent rotating shafts 702 is the same as the spacing between adjacent steps 6, so there is no need to adjust the horizontal position of the step 6 during welding. In addition, there are two mounting plates 703 on the same rotating shaft 702, which are used to set two sets of arc-shaped brackets 704 to support and position the same step 6, ensuring the stability of the support for the step 6.

[0043] The main support 3 has multiple slots 301, which are interconnected. The slots 301 are distributed from top to bottom, and their inner diameters gradually decrease from top to bottom. The slots 301 with gradually decreasing inner diameters are used to hold ladder frames 5 of different thicknesses, which further improves the application range of the tooling. Because the inner diameter of the upper slot 301 is larger and the inner diameter of the lower slot 301 is smaller, it can ensure that the thinner ladder frame 5 can enter the corresponding slot 301 during use.

[0044] There are four arc-shaped brackets 704 on the mounting plate 703, and the four arc-shaped brackets 704 are arranged in a circumferential array on the mounting plate 703. The inner diameters of the four arc-shaped brackets 704 are different, and the distance between the center of the inner diameter of the four arc-shaped brackets 704 and the center of the mounting plate 703 is different. Different arc-shaped brackets 704 are used to hold ladder steps 6 of different thicknesses. Because the center of the inner diameter of different arc-shaped brackets 704 is different from the center of the mounting plate 703, they are used to match the slots 301 at different heights. This ensures that after the ladder frame 5 is inserted into one of the slots 301, the ladder step 6 can also be inserted into the arc-shaped bracket 704 of the corresponding height. Before insertion, the corresponding arc-shaped bracket 704 can be switched by rotating the pivot 702.

[0045] 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. A worm 7051 is fixedly installed on the outer wall of the second rotating shaft 7053. The worm 7051 meshes with a worm wheel 7052. The worm wheel 7052 is fixedly installed on the first rotating shaft 702.

[0046] The spacing adjustment component 4 includes a T-shaped slide rail 401, a positioning hole 402, and a fixing bolt 403. The T-shaped slide rail 401 is fixedly installed on the top of the base plate 1, and the mounting bracket 2 is slidably mounted on the T-shaped slide rail 401. The positioning hole 402 is opened on the top of the base plate 1, and there are two rows of positioning holes 402. The mounting bracket 2 is connected to the positioning hole 402 by the fixing bolt 403.

[0047] The worm gear 7051 and worm wheel 7052 are covered with protective covers 13. The left and right ends of the rotating shaft 7053 extend out from the fixed frame 701, and the left and right ends of the rotating shaft 7053 are fixedly installed with handles 14.

[0048] The positioning component 8 includes an equipotential plate 801, which is fixedly installed on the left end of the base plate 1. A positioning bracket 802 is fixedly installed on the right outer wall of the equipotential plate 801. The left end of the ladder frame 5 passes through the positioning bracket 802 and abuts against the right outer wall of the equipotential plate 801. When placing the ladder frame 5, the left end of the ladder frame 5 needs to be abutted against the right outer wall of the equipotential plate 801. At this time, the positioning bracket 802 positions and locks the end of the ladder frame 5, thereby ensuring that the two ladder frames 5 are parallel and aligned left and right.

[0049] The positioning bracket 802 has a positioning groove corresponding to the slot 301, and the positioning bracket 802 is made of elastic material, so that the positioning bracket 802 can hold ladders 5 of different thicknesses, and the elastic material positioning bracket 802 can better hold the ladders 5.

[0050] A track frame 9 is fixedly installed at the bottom of the base plate 1. Rollers 10 are installed inside the track frame 9. A reinforcing plate 11 is fixedly installed at the bottom of the base plate 1, and a fixed pin 12 is inserted into the positioning hole 402. The track frame 9 is set up to install the rollers 10. When the tooling needs to be moved, the base plate 1 can be pulled directly to move it. When welding, the fixed pin 12 can be passed through the positioning hole 402 and then the fixed pin 12 can be hammered into the ground.

[0051] Working principle: During use, adjust the spacing of the mounting brackets 2 according to the required dimensions of the batch of hanging ladders to be assembled. After adjustment, fix the mounting brackets 2 with fixing bolts 403. Then, rotate the second rotating shaft 7053 to drive the worm gear 7051 to rotate, which in turn drives the worm wheel 7052 to rotate. This causes the worm wheel 7052 to drive the first rotating shaft 702 to rotate, and the rotation of the first rotating shaft 702 drives the mounting plate 703 to rotate. This causes an arc-shaped bracket 704 on the mounting plate 703 to be parallel to the main support 3, and the arc... The inner diameter of the shaped bracket 704 corresponds to the step 6 of the hanging ladder. The ladder frame 5 is placed in the slot 301, and then the two ladder frames 5 are pushed to the left so that the two ladder frames 5 abut against the right side of the equidistant plate 801. When the ladder frame 5 passes through the positioning bracket 802, the positioning bracket 802 can also elastically clamp the ladder frame 5 to achieve alignment of the two ladder frames 5. Then the step 6 is placed in the arc-shaped bracket 704, and the contact parts of the ladder frame 5 and the step 6 are tack welded to complete the quick assembly of the hanging ladder.

[0052] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
