Description

Technical Field

[0001] This invention relates to the field of space frame construction tools, and in particular to a space frame climbing tool. Background Technology

[0002] During the assembly and construction of a building space frame structure, workers often need to climb up and down along the space frame members. In this process, double-hook safety belts are generally used to ensure safety. When climbing, a rope is knotted into a loop, and the worker puts the rope loop around their waist. The rope loop is also put around the space frame member. The worker uses their waist to exert force, grabs the rope with both hands, and uses their legs to climb upwards.

[0003] However, the above-mentioned working method has obvious shortcomings in practical application. First, the surface of the rope is usually quite smooth, with limited friction between the rope and the scaffolding members and the human body. Especially when the scaffolding members are tilted at a large angle (the angle between the scaffolding members and the horizontal plane), the person's center of gravity will lean significantly backward, making the climbing process both strenuous and time-consuming. Second, this working method is physically demanding for the workers, and slippage is easy between the human body and the rope loop, as well as between the rope loop and the scaffolding members, resulting in a high risk factor. Third, the rope loop can also easily cause wear and tear on the paint surface of the scaffolding members.

[0004] Therefore, designing a specialized climbing tool for space frame poles that can improve climbing efficiency, save physical strength, and provide reliable safety protection has become an urgent technical problem to be solved in this field. Summary of the Invention

[0005] The purpose of this invention is to provide a climbing tool for a grid structure. When a worker's foot accidentally slips during the climbing process, even if the hook part shakes, the self-locking half-ring design can effectively prevent it from slipping, thus ensuring the worker's personal safety.

[0006] To achieve the above objectives, the present invention provides a space frame climbing tool, comprising:

[0007] A climbing pole, the climbing pole including a hook part and a pull rod part;

[0008] The self-locking semi-ring has its middle part rotatably connected to the hook part through a pivot point. When the climbing tool is hung on the grid member and subjected to force, the self-locking semi-ring and the hook part together form an open ring to accommodate the grid member. The inner surface of the open ring is a continuous arc surface, and the angle at which the open ring surrounds the grid member is greater than 270°.

[0009] A handle, which is connected to the pull rod.

[0010] Optionally, the length of the pull rod is adjustable.

[0011] Optionally, the pull rod includes an inner tube and an outer tube, as well as a locking structure for locking the relative position of the inner tube and the outer tube.

[0012] Optionally, the inner side of the hook portion is provided with a first anti-slip strip, and the inner side of the self-locking semi-ring is provided with a second anti-slip strip.

[0013] Optionally, the climbing pole, the self-locking semi-ring, and the handle are all made of aluminum alloy.

[0014] Optionally, the pivot point is an elastic pivot point, which has a built-in torsion spring. The torsion spring is used to drive the self-locking half ring away from the inner side of the hook when there is no external force, so as to facilitate the fitting of the self-locking half ring onto the space frame member.

[0015] Optionally, the inner side of the hook is provided with a clearance groove, so that when the climbing tool is hung on the grid pole, the self-locking semi-ring can be accommodated in the clearance groove.

[0016] Optionally, the climbing tool includes a safety rope connected to the handle and used to secure the worker's hands.

[0017] Optionally, the inner surface of the hook portion is an arc-shaped inner surface, with a straight line passing through the center of the arc-shaped inner surface and perpendicular to the axis of the pull rod portion as a reference line, and the end of the hook portion extends beyond the reference line; the central angle corresponding to the arc length of the self-locking semi-ring is greater than 180°.

[0018] Optionally, the hook portion is rotatably connected to the self-locking half-ring at the end of the hook portion.

[0019] As configured above, the present invention provides a space frame climbing tool, comprising: a climbing pole, the climbing pole including a hook portion and a pull rod portion; a self-locking semi-ring, the middle portion of which is rotatably connected to the hook portion via a pivot point; when the climbing tool is hung on a space frame member and subjected to force, the self-locking semi-ring and the hook portion together form an open ring for accommodating the space frame member; the inner surface of the open ring is a continuous arcuate surface, and the angle at which the open ring surrounds the space frame member is greater than 270°; and a handle connected to the pull rod portion.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] In the climbing tool of this invention, the self-locking semi-ring and the hook portion together form an open ring with an enclosure angle greater than 270°, reliably enclosing the space frame members within it. Even if the hook portion wobbles and the worker's foot slips during climbing, the self-locking semi-ring has already "caught" the space frame member from below, preventing the climbing tool from easily detaching from it and effectively ensuring the worker's safety.

[0022] Furthermore, anti-slip strips are provided on the hook part and the inner side of the self-locking semi-ring. On the one hand, this significantly increases the coefficient of friction with the space frame members, allowing workers to obtain a stable foothold when climbing, saving energy and increasing climbing speed. On the other hand, the anti-slip strips can be made of rubber, which will not scratch the anti-corrosion paint surface of the space frame members, thus helping to maintain the anti-corrosion performance of the space frame members.

[0023] Furthermore, the length of the pull rod is adjustable (e.g., using an inner and outer tube with a locking structure), allowing workers of different heights or arm lengths to quickly adjust it to the required length according to their individual needs and the specific conditions of the scaffold members, making it widely applicable. The handle is equipped with an anti-slip rope to further prevent accidental slippage of the climbing equipment, improving safety during high-altitude operations. Attached Figure Description

[0024] Those skilled in the art will understand that the accompanying drawings are provided to better understand the invention and do not constitute any limitation on the scope of the invention. Wherein:

[0025] Figure 1 This is a schematic diagram of a space frame climbing tool according to an embodiment of the present invention;

[0026] Figure 2 This is a schematic diagram of the initial position of a space frame climbing tool according to an embodiment of the present invention.

[0027] The accompanying figure is labeled as follows:

[0028] 1-Climbing pole; 11-Hook part; 111-First anti-slip strip; 112-Giveaway groove; 113-End of hook part; 12-Pull rod part; 121-Outer tube; 1211-Positioning hole; 2-Self-locking half ring; 21-Turn point; 3-Handle; 4-Anti-slip rope; 5-Straight line. Detailed Implementation

[0029] In this document, unless otherwise stated, the terms “upper,” “lower,” “left,” “right,” “inner,” “outer,” “front,” “back,” “top,” “bottom,” etc., are used to indicate orientation or positional relationship based on the accompanying drawings, and are only for the convenience of describing the invention and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a characteristic orientation and operation, and therefore should not be construed as a limitation of the invention.

[0030] The specific embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. The advantages and features of the present invention will become clearer from the following description. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of the present invention.

[0031] Figure 1 This is a schematic diagram of a space frame climbing tool according to an embodiment of the present invention. Figure 2 This is a schematic diagram showing the initial position of a space frame climbing tool according to an embodiment of the present invention. Please refer to... Figure 1 and Figure 2 This invention provides a climbing tool for a grid structure, which includes a climbing pole 1, a self-locking half ring 2, and a handle 3.

[0032] The climbing pole 1 includes a hook part 11 and a pull rod part 12, and the handle 3 is connected to the pull rod part 12.

[0033] The middle part of the self-locking semi-ring 2 is rotatably connected to the hook part 11 via a pivot point 21. Further, the position where the hook part 11 is rotatably connected to the self-locking semi-ring 2 is the end of the hook part 11. Preferably, the inner surface of the hook part 11 is an arc-shaped inner surface. Using a straight line 5 passing through the center of the arc-shaped inner surface and perpendicular to the axis of the pull rod part 12 as a reference line, the end 113 of the hook part extends beyond the reference line, so that the area of ​​the hook part 11 surrounding the space frame member is larger, making it less likely to detach from the space frame member.

[0034] It should be noted that the "half" in the name of the self-locking semi-ring described in this invention does not imply a strict mathematical limitation of 180° for its arc length. In fact, both the self-locking semi-ring 2 and the hook portion 11 are open arc-shaped structures, and their arc lengths may be equal or unequal. The term "semi-ring" is used in this invention only as a component name for ease of understanding; its actual arc length can be adjusted according to the diameter of the space frame member and the required self-locking force. Preferably, the central angle corresponding to the arc length of the self-locking semi-ring 2 is greater than 180°. When the climbing tool is attached to a space frame member (not shown in the figure) and subjected to force, the self-locking semi-ring 2 and the hook part 11 together form an open ring to accommodate the space frame member. The inner surface of the open ring is a continuous arc surface, and the angle of the open ring surrounding the space frame member is greater than 270°. In this way, the tool is self-locked during the climbing process. For example, if the worker's foot accidentally slips during the climbing process, even if the hook part 11 shakes, the climbing tool cannot easily fall off the space frame member because the self-locking semi-ring 2 has "held" it from below, effectively ensuring the personal safety of the worker.

[0035] Preferably, the radius of the self-locking semi-ring 2 is the same as the radius of the arc of the hook portion 11. The inner side of the hook portion 11 is provided with a clearance groove 112, so that when the climbing tool is hung on the frame member, the self-locking semi-ring 2 can be accommodated within the clearance groove 112. For example, the depth of the clearance groove 112 is half the thickness of the hook portion 11. When the climbing tool is hung on the frame member, the self-locking semi-ring 2 can rotate into the clearance groove 112, and at this time, the inner side of the self-locking semi-ring 2 is flush with the inner side of the hook portion 11, forming a continuous arc surface, so that the climbing tool is hung more securely. Figure 2 The clearance groove 112 extends all the way to the position near the pull rod 12. During rotation, the end of the self-locking half ring 2 may interfere with the position of the hook part 11 near the pull rod 12. Figure 2 Since the distance between the end of the self-locking half-ring 2 and the hook portion 11 is very small, continued rotation may cause interference. Therefore, the clearance groove 112 is extended to this position to prevent interference. In some embodiments, the clearance groove 112 may extend to the end 113 of the hook portion, thereby allowing for rotation of the self-locking half-ring 2; in other embodiments, the clearance groove 112 may not extend to the end 113 of the hook portion, but the end 113 of the hook portion may be hollow (e.g., ...). Figure 2 As shown in the figure, it can also make way for the rotation of the self-locking half ring 2.

[0036] Preferably, the inner side of the hook portion 11 is provided with a first anti-slip strip 111, and the inner side of the self-locking semi-ring 2 is provided with a second anti-slip strip (not shown in the figure). The anti-slip strip can be made of rubber, for example, to prevent slipping and to prevent the climbing tool from damaging the paint surface of the grid frame members when force is applied.

[0037] Furthermore, the pivot point 21 is an elastic pivot point, and the elastic pivot point has a built-in torsion spring. The torsion spring is used to drive the self-locking semi-ring 2 away from the inner side of the hook portion 11 when there is no external force, such as... Figure 2 As shown in the figure, the position of the self-locking half ring 2 is the initial position. It can be understood that when it is not hung on the space frame member, the self-locking half ring 2 is in the initial position due to the force of the torsion spring. When it is to be used, the self-locking half ring 2 can be conveniently and quickly put on the space frame member.

[0038] Preferably, the length of the pull rod portion 12 is adjustable. For example, the pull rod portion 12 includes an inner tube and an outer tube 121, as well as a locking structure for locking the relative position of the inner tube and the outer tube 121. For example, the outer tube 121 is provided with a plurality of spaced positioning holes 1211, and the inner tube is provided with a through hole (not shown in the figure). According to the length requirement, a bolt is inserted into a specific positioning hole 1211. The bolt passes through the positioning hole 1211 of the outer tube 121 and the through hole of the inner tube, penetrating both the outer tube 121 and the inner tube. It can be understood that after the bolt passes through the outer tube 121 and the inner tube, the bolt is tightened with a nut, that is, the head of the nut and the bolt clamps the outer tube 121 in the middle.

[0039] The climbing pole 1, the self-locking semi-ring 2, and the handle 3 are all made of aluminum alloy. Aluminum alloy has the advantages of being lightweight and having good mechanical properties, making it easy to carry and operate, and suitable for mass production. The handle 3 is preferably a ring handle, such as a rectangular ring handle, for easy application of force. The climbing tool includes an anti-slip rope 4, which is connected to the handle 3. The anti-slip rope 4 is used to loop around the worker's hands to prevent them from slipping during climbing, further ensuring the worker's safety.

[0040] As configured above, the present invention provides a climbing tool for a space frame, comprising: a climbing pole 1, the climbing pole 1 including a hook portion 11 and a pull rod portion 12; a self-locking semi-ring 2, the middle part of the self-locking semi-ring 2 being rotatably connected to the hook portion 11 via a pivot point 21, wherein when the climbing tool is hung on a space frame member and subjected to force, the self-locking semi-ring 2 and the hook portion 11 together form an open ring for accommodating the space frame member, the inner surface of the open ring being a continuous arc surface, and the angle at which the open ring surrounds the space frame member being greater than 270°; and a handle 3 connected to the pull rod portion 12.

[0041] The general method of using the climbing tool of this invention is as follows:

[0042] Adjust the length of the pull rod according to your needs and put the anti-drop rope around your wrist; hold one climbing tool of the present invention in each hand, put the self-locking half ring 2 on the net frame pole, and then push the self-locking half ring 2 into the relief groove 112 on the inner side of the hook part 11, so that the climbing tool hooks the net frame pole and pulls it tight; climb with your hands and feet.

[0043] Compared with the prior art, the present invention has the following beneficial effects:

[0044] In the climbing tool of the present invention, the self-locking semi-ring 2 and the hook part 11 together form an open ring with an enclosure angle greater than 270°, so that the grid frame members are reliably surrounded therein. When the worker's foot accidentally slips during the climbing process, even if the hook part 11 shakes, the climbing tool cannot easily detach from the grid frame members because the self-locking semi-ring 2 has already "caught" the grid frame members from below, effectively ensuring the personal safety of the worker.

[0045] Furthermore, anti-slip strips are provided on the inner sides of the hook part 11 and the self-locking semi-ring 2. On the one hand, this significantly increases the coefficient of friction with the space frame members, allowing workers to obtain a stable point of leverage when climbing, saving energy and increasing climbing speed. On the other hand, the anti-slip strips can be made of rubber, which will not scratch the anti-corrosion paint surface of the space frame members, thus helping to maintain the anti-corrosion performance of the space frame members.

[0046] Furthermore, the length of the pull rod 12 is adjustable (for example, by using an inner tube and an outer tube 121 with a locking structure), allowing workers of different heights or arm lengths to quickly adjust it to the required length according to their individual needs and the specific conditions of the space frame members, making it widely applicable. The handle 3 is connected to an anti-slip rope 4, further preventing accidental slippage of the climbing tool and improving the safety of working at heights.
