Description

Technical Field

[0001] This utility model relates to the field of training support technology, and in particular to a lightweight high-altitude rope training support. Background Technology

[0002] According to the high-altitude rope training frame disclosed in Chinese Publication No. CN214551056U, it includes a frame body and a ladder. The frame body includes a ladder located on the right side of the frame body; a first-level platform located in the middle of the ladder; a second-level platform located on the upper section of the ladder; a confined space located on the second-level platform; a straight ladder located on the outer wall of the frame body; and a rescue platform fixed to one side of the middle of the frame body. This high-altitude rope training frame features a ladder that leads to both the first and second-level platforms. The stepped ladder closely mimics the structure of a building, making the training more realistic. The confined space simulates structures such as pipes and wells, allowing rescuers to simulate rescue operations in confined spaces, effectively improving the functionality of the device. The interconnections are welded, effectively avoiding the problem of long construction cycles associated with traditional buildings and significantly reducing costs.

[0003] The aforementioned and existing high-altitude rope training techniques are mostly conducted within dedicated training grounds using fixed steel structure frames. These frames are typically installed using welding or prefabrication. While these structures offer strong stability and load-bearing capacity, they suffer from drawbacks such as heavy weight, difficulty in transportation, long installation periods, and strong dependence on specific locations, making them unsuitable for flexible deployment and rapid assembly off-site. Utility Model Content

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a lightweight high-altitude rope training support, comprising two first columns and two second columns. Each of the two first columns has a first crossbar on both sides of its bottom end. Each of the two second columns has a first crossbar on one side of its top end and a second crossbar on the other side of its top end. Two training crossbars are located between the two second crossbars. A ladder is located between the first and second columns. The two first columns and two second columns are arranged in a rectangular arrangement, with the two first columns and two second columns installed diagonally. Each of the top ends of the two first columns near the two sides of the two second columns has a first connecting seat, and each of the bottom ends of the two first columns near the two sides of the two second columns has a connecting frame. The top ends of the two second columns near the two sides of the two first columns... Each column is equipped with a connecting frame, and the bottom ends of the two second columns are provided with first connecting seats on both sides of the two first columns. The connecting frame and the first connecting seats are welded to the first and second columns. One end of each of the six first crossbars and the two second crossbars is provided with a pin hole, and the other end of each of the first and second crossbars is provided with a flange. The pin holes on the surfaces of the six first and second crossbars are provided with pins, and the top of each pin is provided with a fixing bolt. Flanges are provided on both sides of the two training crossbars. Two second connecting seats are provided on the sides of the two second crossbars. The bottom surfaces of the two training crossbars are provided with hanging ears in a horizontal array. The flanges are welded to the training crossbars, the first crossbars and the second crossbars. The top and bottom ends of the two first columns are provided with diagonal braces on both sides of the two second columns, and the top and bottom ends of the two second columns are provided with diagonal braces on both sides of the two first columns.

[0006] Preferably, the ends of the first crossbars on both sides of the bottom of the two first columns with pin holes are all pinned to the connecting brackets on both sides of the bottom of the first column by pin shafts, and the ends of the first crossbars with flanges are all connected to the first connecting seat flanges on both sides of the bottom of the second column.

[0007] Preferably, the ends of the first crossbar on one side and the second crossbar on the other side of the top of the two second columns, which are provided with pin holes, are pinned to two connecting brackets on the top surface of the second column by pin shafts, and the ends of the first crossbar and the second crossbar provided with flanges are connected to the first connecting seat flanges on both sides of the top surface of the first column. The pin shafts are all bolted to the connecting brackets by fixing bolts.

[0008] Preferably, one end of each of the two diagonal braces on both sides of the bottom of the two first columns and the two second columns is bolted to the first column and the second column, and the other end of each diagonal brace is bolted to the first crossbar.

[0009] Preferably, one end of the diagonal brace at the top of each of the two first columns and the two second columns near the first horizontal bar is bolted to the first column and the second column, and the other end of the diagonal brace is bolted to the first horizontal bar.

[0010] Preferably, the lugs on the bottom surface of both training crossbars are welded to the training crossbars, and the flanges at both ends of the training crossbars are connected to the second connecting seat flanges on the sides of the two second crossbars.

[0011] Preferably, the ladder is positioned between the two training crossbars, with the top of the ladder bolted to the second crossbar and the bottom of the ladder bolted to the first crossbar.

[0012] Beneficial effects In this invention, when installing the off-site training support, the first step is to determine the position of the support on a flat surface according to the training requirements. Two first uprights and two second uprights are arranged in a rectangular pattern and fixed to the ground using bolts. During the initial installation, the two first uprights are placed diagonally and locked with bolts to ensure stable support on the ground. Then, the two first horizontal bars at the bottom of the first uprights are unfolded sequentially. To ensure a consistent height after installation, pads or bricks can be placed under the ends of the horizontal bars at the bottom of the first uprights to keep the horizontal height of the first horizontal bars on the same level as the first connecting seat at the bottom of the second uprights, allowing for accurate alignment of the first horizontal bars and connecting seats laterally. Subsequently, two second columns were installed at two other diagonal positions within the rectangular arrangement and fixed to the ground using bolts. Simultaneously, the first and second horizontal bars at the base of the second columns were unfolded. A crane was used to slowly move and fine-tune the second columns, ensuring that the flanges of the first and second horizontal bars at their tops accurately aligned with the first connecting seats at the tops of the two diagonally positioned first columns. Furthermore, the two first connecting seats at their tops were ensured to tightly align with the flanges of the first horizontal bars on both sides of the first columns. Once aligned, all first and second horizontal bars were individually locked with bolts, forming a preliminary frame connection. After the above structural assembly was completed, diagonal braces were installed between the first and second horizontal bars and fixed with bolts, forming a stable triangular load-bearing system to enhance the overall frame's stability and anti-tilting capacity. After the second horizontal bars were reinforced, the flanges at both ends of the training horizontal bar were aligned and fitted with the flanges of the second connecting seats on the sides of the second horizontal bar, and then tightened with bolts, ensuring the training horizontal bar was securely installed in the middle of the support frame. Next, a ladder is installed between the two training crossbars. During installation, the top of the ladder is first reliably connected to the second crossbar with bolts, and then the bottom of the ladder is fixed to the first crossbar with bolts, ensuring a secure connection between the ladder and the crossbars and the ability to withstand training loads. The entire installation is completed by fixing the two first and second uprights, rotating and connecting the first and second crossbars, and securing them with diagonal braces. Once the frame is installed, the training crossbars and ladder are then installed to complete the overall installation. The installation process is simple and quick, overcoming the shortcomings of being unsuitable for flexible deployment and rapid assembly off-site. Attached Figure Description

Flanges 15 are welded to the training crossbars 12, the first crossbar 5, and the second crossbar 6. Diagonal braces 10 are provided on both the top and bottom ends of the two first columns 1 near the two second columns 2. Similarly, diagonal braces 10 are provided on both the top and bottom ends of the two second columns 2 near the two first columns 1. One end of the first crossbar 5 on both sides of the bottom end of the two first columns 1 has pin holes 14 and is pinned to the connecting brackets 3 on both sides of the bottom end of the first column 1 via pin shafts 8. One end of the first crossbar 5 with flanges 15 is connected to the flanges of the first connecting seats 4 on both sides of the bottom end of the second columns 2. Pins are provided on one side of the first crossbar 5 and the other side of the second crossbar 6 at the top of the two second columns 2. One end of each hole 14 is pinned to two connecting brackets 3 on the top surface of the second column 2 via pins 8. The ends of the first crossbar 5 and the second crossbar 6 with flanges 15 are connected to the flanges of the first connecting seats 4 on both sides of the top surface of the first column 1. Pins 8 are bolted to the connecting brackets 3 via fixing bolts 9. One end of each of the two diagonal braces 10 on both sides of the bottom of the two first columns 1 and the two second columns 2 is bolted to the first column 1 and the second column 2, and the other end of each diagonal brace 10 is bolted to the first crossbar 5. One end of each diagonal brace 10 on the top of the two first columns 1 and the two second columns 2 near the first crossbar 5 is bolted to the first column 1 and the second column 2, and the other end of each diagonal brace 10 is bolted to the first crossbar 5.One end of the diagonal brace 10 at the top of each of the two first uprights 1 and the two second uprights 2, near the second horizontal bar 6, is bolted to the first upright and the second upright 2, and the other end of each diagonal brace 10 is bolted to the second horizontal bar 6. The lugs 13 on the bottom of each of the two training horizontal bars 12 are welded to the training horizontal bars 12, and the flanges 15 at both ends of each training horizontal bar 12 are connected to the flanges of the second connecting seats 7 on the sides of the two second horizontal bars 6. A ladder 11 is positioned between the two training horizontal bars 12, with its top end bolted to the second horizontal bar 6 and its bottom end bolted to the first horizontal bar 5.

[0018] The first column 1 and the second column 2 serve as the load-bearing components of the overall support structure. They are reliably fixed to the ground by fixing bolts 9 at their bottom ends, bearing the main vertical load and a portion of the horizontal force when under stress. Connecting frames 3 are welded to the bottom of the first column 1 and the top of the second column 2. First connecting seats 4 are welded to both sides of the top of the first column 1 and the bottom of the second column 2. The connecting frames 3 serve as the pin connection points between the first crossbar 5 and the second crossbar 6 and the first column 1 and the second column 2. They are connected to the pin shaft 8 through pin holes 14 and reinforced by fixing bolts 9 to ensure that the first crossbar 5 and the second crossbar 6 do not loosen axially during use. The first connecting seats 4 serve as flange connection points, fastened to the flanges 15 at the ends of the first crossbar 5, the second crossbar 6, or the training crossbar 12 by bolts. This creates a reliable flange-like fit between the columns and crossbars, resulting in more even force transmission and avoiding single-point stress. The first crossbar 5 and the second crossbar 6 serve as the lateral load-bearing components of the support. One end of each crossbar has a pin hole 14 connected to the connecting frame 3, and the other end has a flange 15 securely connected to the first connecting seat 4, forming a stable rectangular frame after installation. The pin holes 14 of the crossbars are connected by pins 8 and then locked by fixing bolts 9, ensuring that the crossbars can withstand both tensile and bending moments under load, preventing slippage and improving overall connection rigidity. The second connecting seat 7 is located on the side of the second crossbar 6, serving as the installation interface for the training crossbar 12. Its flange face on one side mates with the flanges 15 at both ends of the training crossbar 12, and is secured with bolts, allowing the training crossbar 12 to be firmly fixed between the two second crossbars 6. The training crossbar 12, as the main load-bearing component for high-altitude training, has multiple hanging ears 13 welded to its bottom surface. These hanging ears 13 can be used to attach training ropes, safety belts, or other auxiliary training equipment, thereby expanding the functionality of the support. The lug 13 is integrally welded to the training crossbar 12, allowing the load to be evenly distributed to the body of the training crossbar 12, preventing damage caused by excessive local stress. The diagonal brace 10, acting as a reinforcing member, is installed between the first upright 1, the second upright 2, and the first and second crossbars 5 and 6. Its two ends are bolted to the junction of the uprights and crossbars, forming a triangular reinforcement structure that significantly improves the overall lateral force resistance of the frame, preventing tilting or swaying of the support structure due to lateral loads or personnel movement during training. The ladder 11 is installed between the two training crossbars 12, with its top bolted to the second crossbar 6 and its bottom bolted to the first crossbar 5, serving as a climbing passage. The ladder 11 not only provides a passage for trainees to access the high crossbars, but its vertical force is also transferred to the crossbars via bolts and further distributed to the uprights and the ground, thus combining climbing functionality with structural stability assistance. The pin 8 and the fixing bolt 9 work together at the pin connection points between the first crossbar 5 and the second crossbar 6 and the connecting frame 3. The pin 8 serves as a positioning and insertion point, while the fixing bolt 9 provides axial locking. Together, they prevent the first crossbar 5 and the second crossbar 6 from axially slipping due to force.Flange 15 serves as the primary connecting surface, fastened to the first connecting seat 4 and the second connecting seat 7 with bolts, ensuring a large contact area between the crossbar and the upright or training crossbar 12, thereby guaranteeing stable force transmission and high shear strength. It should be noted that the two first crossbars 5 at the bottom of the first upright 1 are pre-connected and installed via pins 8, and the first crossbar 5 and second crossbar 6 of the second upright 2 are also connected to the second upright 2 via pins 8. During disassembly, the first crossbars 5 and second crossbar 6 are rotated and folded, fitting snugly against the first upright 1 and the second upright 2, and secured with ropes. In use, the ropes are untied, and the first crossbars 5 and second crossbar 6 are unfolded.

[0019] During installation, after the uprights are connected to the ground via fixing bolts 9, the first horizontal bar 5 and the second horizontal bar 6 are deployed and positioned using pins 8 and connecting frames 3, and rigidly fixed to the first connecting seat 4 via flanges 15, initially forming a rectangular frame. Subsequently, diagonal braces 10 form a triangular force-bearing structure between the uprights and horizontal bars, significantly enhancing the frame's stability and anti-tilting ability. After the frame is reinforced, the training horizontal bar 12 is installed between the two second horizontal bars 6 via flange connections, and the installation function of training accessories is realized through welded lugs 13. Finally, the ladder 11 is installed between the first horizontal bar 5 and the second horizontal bar 6, providing a vertical climbing passage. After the overall frame is formed, all forces are distributed to the uprights through the horizontal bars and training horizontal bars 12, and finally transferred to the ground by the uprights via fixing bolts 9, ensuring stability and safety during training. Specific Implementation Example 2: Reference Figure 1-5A lightweight aerial rope training support is further based on the basic structure in Specific Embodiment 1. During the installation and use of this lightweight aerial rope training support, the first column 1 and the second column 2 serve as vertical load-bearing components, reliably fixed to the ground by fixing bolts 9 at their bottom ends. The columns bear the main vertical load and share a portion of the horizontal force in the overall structure. The connecting frame 3 welded to the bottom of the first column 1 and the top of the second column 2 serves as the pin connection point for the first crossbar 5 and the second crossbar 6. The pin hole 14 at the end of the crossbar engages with the pin shaft 8, and is then locked by fixing bolts 9, ensuring that the crossbar does not slip in the axial position. At this time, the other end of the crossbar is attached to the first connecting seat 4 on the surface of the column via a flange 15 and secured with bolts, forming a stable flange connection between the crossbar and the column. This makes the force transmission more uniform and avoids localized damage caused by concentrated force at a single point. As the first horizontal bar 5 and the second horizontal bar 6 are gradually unfolded and fixed, a stable rectangular frame is formed. The horizontal bars not only transmit horizontal forces between the columns, but also ensure the stability of the structure and the reliability of the connection through the pins 8 and flanges 15 when under tension and bending. After the frame is initially formed, the diagonal bars 10 are installed between the columns and the horizontal bars, forming a triangular force-bearing system through bolt connection. This significantly improves the frame's resistance to lateral forces, enabling the whole structure to withstand lateral swaying and impacts generated during training, further ensuring that the support does not tilt or sway. The side of the second horizontal bar 6 is provided with a second connecting seat 7. The flanges 15 at both ends of the training horizontal bar 12 are connected to its flange face and locked with bolts. The training horizontal bar 12 is thus firmly fixed between the two second horizontal bars 6, serving as the main training load-bearing component. The hanging lugs 13 at the bottom of the training horizontal bar 12 are welded to its body for hanging training ropes or protective equipment. The load borne by the hanging lugs 13 is evenly transmitted to the training horizontal bar 12, and then the training horizontal bar 12 transmits the force to the second horizontal bars 6 on both sides and finally to the columns and the ground, avoiding local stress concentration. A ladder 11 is installed between two training crossbars 12. Its top end is bolted to the second crossbar 6, and its bottom end is bolted to the first crossbar 5, forming a safe climbing passage. Trainees can easily access the training crossbar 12 area via the ladder 11. While providing climbing access, the ladder 11 also transmits vertical force to the crossbars and further distributes it to the uprights, thus providing both load-bearing and stabilizing support during use. Throughout the assembly process, the pin 8 and the fixing bolt 9 work together at the insertion point between the crossbar and the connecting frame 3. The pin 8 provides positioning and insertion, while the fixing bolt 9 provides axial locking. Together, they ensure that the crossbar will not shift or loosen under load. The flange 15 is bolted to the first connecting seat 4 or the second connecting seat 7, ensuring a large contact area between the crossbar and the upright or training crossbar 12, enhancing the shear strength of the connection and the overall rigidity.When not in use, the first and second crossbars 5 and 6 can be pre-connected to the uprights via pins 8. After rotating and folding, the crossbars fit snugly against the uprights and are secured with straps or ropes for easy transport and storage. In use, simply untie the straps and unfold the crossbars for quick setup. The overall working principle is that the uprights, as the main load-bearing components, transfer vertical loads and horizontal forces to the ground; the crossbars, as lateral load-bearing components, provide a stable connection between the uprights and withstand tension and bending moments; the triangular reinforcement system formed by the diagonal braces 10 resists lateral swaying and side forces; the training crossbar 12 is securely installed via the second connecting seat 7 and bears the operational load during training; the hanging lugs 13 evenly distribute additional loads; the ladder 11 provides climbing functionality while sharing vertical forces; pins 8 and fixing bolts 9 together ensure the reliability of the connection; flanges 15 and connecting seats ensure even force transmission and overall connection rigidity; all forces are ultimately transferred to the ground through the uprights and the bottom fixing bolts 9, thus forming a stable, easy-to-install, and multifunctional high-altitude rope training support.

[0021] In summary: 1. When installing the off-site training support, first determine the placement of the support on a flat surface according to the training requirements. Arrange the two first uprights 1 and two second uprights 2 in a rectangular pattern and fix them to the ground using fixing bolts 9. During the initial installation, place the two first uprights 1 diagonally and lock them with fixing bolts 9 to ensure stable support on the ground. Then, unfold the two first horizontal bars 5 at the bottom of the first uprights 1 one by one. To ensure that the overall height of the uprights is consistent after installation, pads or bricks can be placed under the ends of the horizontal bars at the bottom of the first uprights 1 to keep the horizontal height of the first horizontal bar 5 on the same horizontal plane as the first connecting seat 4 at the bottom of the second uprights 2, so that the first horizontal bar 5 and the connecting seat can fit accurately afterward. Subsequently, two second columns 2 are installed at two other diagonal positions in the rectangular arrangement and fixed to the ground using bolts 9. Simultaneously, the first horizontal bar 5 and second horizontal bar 6 at the bottom of the second columns 2 are unfolded. A crane is used to slowly move and fine-tune the second columns 2, ensuring that one end of the flange 15 of the first horizontal bar 5 and second horizontal bar 6 at the top of the second columns 2 accurately aligns with the first connecting seat 4 at the top of the two diagonally positioned first columns 1. Furthermore, the two first connecting seats 4 at the top are made to fit tightly with the flange 15 of the first horizontal bar 5 on both sides of the first column 1. After proper alignment, all first horizontal bars 5 and second horizontal bars 6 are locked together one by one using bolts 9, forming a preliminary frame connection. After the above structural assembly is completed, diagonal braces 10 are installed between the first horizontal bars 5 and second horizontal bars 6 and fixed with bolts, thus forming a stable triangular force-bearing system to enhance the overall frame's stability and anti-tilting ability. After the second crossbar 6 is reinforced and connected, align and fit the flanges 15 at both ends of the training crossbar 12 with the flanges of the second connecting seat 7 on the side of the second crossbar 6, and tighten them with fixing bolts 9 to secure the training crossbar 12 firmly in the middle of the support frame. Then, install the ladder 11 between the two training crossbars 12. During installation, first reliably connect the top of the ladder 11 to the second crossbar 6 with bolts, and then fix the bottom of the ladder 11 to the first crossbar 5 with bolts, ensuring a secure connection between the ladder 11 and the crossbar and its ability to withstand the training load. The entire installation only requires fixing the two first columns 1 and the second column 2, rotating and connecting the first crossbar 5 and the second crossbar 6, and securing them with diagonal braces 10. Once the frame is installed, install the training crossbar 12 and the ladder 11 to complete the overall installation. The installation process is simple and quick, solving the shortcomings of not being suitable for flexible deployment and rapid assembly off-site.
