Description

Technical Field

[0001] The utility model relates to the technical field of construction operation equipment, in particular to a safety belt hanging device used for a beam bottom. Background Art

[0002] High-altitude work is often required in the construction industry. Generally, the vertical height of the floor slab or beam bottom of a building will exceed 2 meters from the ground, or even higher. After the construction of the building floor structure is completed, the construction workers may perform processes such as grinding, plastering, painting or equipment installation on the bottom of the concrete beam and the lower surface of the floor slab. If the construction method of setting up a full-floor scaffold or multiple rows of scaffolds from the ground is adopted, a lot of manpower and material resources will be consumed, and the construction cost will increase. At the same time, the ground occupied by the scaffolding will also affect the construction of other professions. Therefore, in most cases, construction workers will use gantry scaffolds, mobile scaffolds, herringbone ladders, straight ladders, lifting equipment, or set up simple springboards to carry out high-altitude work in this situation. The advantages of this solution include: saving manpower and material resources, reducing costs, reducing floor space, and creating space for other professional construction. However, during the construction process of this solution, there may be a situation where the safety belt cannot be hung high and used low, or the hanging position of the safety belt is not firm, or even there is no place to hang the safety belt. The construction safety factor is relatively low, the risk is relatively high, and it is easy to cause a high-fall accident. Utility Model Content

[0037] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0038] The utility model provides a safety belt hanging device for beam bottom, such as Figure 1-Figure 5As shown, it includes: a support member 10, a first clamping member 21, a second clamping member 22, a locking structure 50 and an anti-falling diagonal brace member 60, the first clamping member 21 and the second clamping member 22 are both installed on the support member 10, and at least one of the first clamping member 21 and the second clamping member 22 can move relative to the support member 10 to adjust the distance between the first clamping member 21 and the second clamping member 22; the locking structure 50 is used to lock the movable first clamping member 21 and / or the second clamping member 22 to the support member 10; at least one anti-falling diagonal brace member 60 is rotatably hinged to the second clamping member 22, and the anti-falling diagonal brace member 60 has a diagonal brace portion 61 and a hoisting portion 62; the first clamping member 21 and the second clamping member 22 are used to clamp on both sides of the concrete beam 80, and the hoisting portion 62 of the anti-falling diagonal brace member 60 is used to drive the diagonal brace portion 61 to swing upward until it is tightly against the side wall of the concrete beam 80 when subjected to a downward force.

[0039] When in use, the first clamping member 21 and the second clamping member 22 are clamped on both sides of the concrete beam 80, so that the safety belt suspension device is suspended on the concrete beam 80. The safety belt can be directly or indirectly installed on the hoisting part 62, and the safety belt applies a downward force to the hoisting part 62, causing the anti-falling diagonal brace 60 to rotate or have a tendency to rotate, so that the diagonal brace 61 is pressed against the side wall of the concrete beam 80. Due to the action of the first clamping member 21 and the second clamping member 22, the overall position of the anti-falling diagonal brace 60 is restricted. Therefore, when the anti-falling diagonal brace 60 rotates or has a tendency to rotate due to the downward force of the safety belt, a large pressure is generated between the diagonal brace 61 and the side wall of the concrete beam 80, and then a large friction force is generated to prevent the safety belt suspension device from sliding down relative to the concrete beam 80, so that the position of the safety belt suspension device remains stable, and the safety belt is firmly and reliably suspended on the safety belt suspension device.

[0040] In one embodiment, the safety belt hanging device for the bottom of the beam includes a hanger 70, which is rotatably hinged to the hanging portion 62 of the anti-dropping diagonal brace 60. The safety belt can be hung on the hanger 70, and the hanger 70 applies a downward force to the anti-dropping diagonal brace 60, which is conducive to keeping the direction of the force on the anti-dropping diagonal brace 60 downward. Preferably, the anti-dropping diagonal brace 60 and the second clamping member 22 are hinged by a first hinge shaft 600, and the hanger 70 and the hanging portion 62 are hinged by a second hinge shaft 621; the first hinge shaft 600 and the second hinge shaft 621 are parallel, and the first hinge shaft 600 and the second hinge shaft 621 can be connected by hinge bolts.

[0041] In one embodiment, the sling 70 is a sling ring 71, such as Figure 3As shown, the lifting ring 71 is set in a U shape, and a through hole is set at the upper end of the lifting ring 71. The lifting ring 71 and the anti-falling diagonal support member 60 are hinged through a second hinge shaft 621 set in the through hole to ensure that the lifting ring 71 always keeps naturally drooping. Figure 3 As shown, the U-shaped lifting ring 71 has a through slot 72, and the support member 10 can pass through the through slot 72. Preferably, the second hinge shaft 621 is parallel to the side wall of the concrete beam 80.

[0042] Furthermore, if Figure 2 and Figure 3 As shown, the diagonal brace 61 and the hanging part 62 are located on both sides of the hinge between the anti-drop diagonal brace 60 and the second clamping member 22, that is, the diagonal brace 61 and the hanging part 62 are located on both sides of the first hinge shaft 600, so that the anti-drop diagonal brace 60 forms a lever mechanism. When the hanging part 62 is subjected to a downward force, the diagonal brace 61 has an upward rotation or upward rotation tendency, so that the diagonal brace 61 is pressed against the concrete beam 80. Preferably, the anti-drop diagonal brace 60 can extend in a straight line, and the diagonal brace 61 is closer to the first clamping member 21 than the hanging part 62; when the safety belt suspension device is installed on the concrete beam 80, the anti-drop diagonal brace 60 is inclined, and the diagonal brace 61 is inclined downward in the direction from the first hinge shaft 600 to the concrete beam 80. The greater the downward force applied by the safety belt, the greater the force that can be generated between the diagonal brace 61 and the concrete beam 80.

[0043] Furthermore, the length of the diagonal bracing portion 61 is smaller than the length of the hanging portion 62, which is conducive to generating a relatively large pressure between the diagonal bracing portion 61 and the concrete beam 80 when the hanging portion 62 is subjected to a downward force. Preferably, the length of the diagonal bracing portion 61 is smaller than the length of the hanging portion 62, and the weight of the diagonal bracing portion 61 is smaller than the weight of the hanging portion 62, so that the diagonal bracing portion 61 can be pressed against the concrete beam 80 by the deadweight of the anti-falling diagonal bracing member 60 and the hanging device 70.

[0044] In one embodiment, the end face 611 of the diagonal brace portion extends along the axial direction of the hinge axis of the anti-drop diagonal brace member 60 and the second clamping member 22. The hinge axis of the anti-drop diagonal brace member 60 and the second clamping member 22 is the first hinge axis 600, that is, the thickness direction of the diagonal brace portion 61 is parallel to the axial direction of the first hinge axis 600. The end face 611 of the diagonal brace portion is in an arc shape, which is conducive to tightly contacting with the side wall of the concrete beam 80 and generating a relatively large contact area to improve the firmness of the safety belt suspension device suspended on the concrete beam 80. With the first hinge axis 600 as the axis, using the principle of lever, the greater the downward force on the hanging part 62 of the anti-drop diagonal brace member 60, the greater the force of the diagonal brace portion 61 of the anti-drop diagonal brace member 60 clamping the side wall of the concrete beam 80.

[0045] Furthermore, the diagonal brace 61 has a rubber pad 612, which constitutes at least part of the end surface of the diagonal brace 61. The rubber pad 612 is pressed against the side wall of the concrete beam 80, which is conducive to improving friction and can protect the outer surface of the concrete beam 80 from damage to a certain extent. In one embodiment, the end of the diagonal brace 61 is wrapped with the rubber pad 612.

[0046] After the diagonal brace portion 61 of the anti-falling diagonal brace member 60 is pressed against the side wall of the concrete beam, the greater the downward pulling force of the safety belt on the anti-falling diagonal brace member 60, the stronger the tendency of the diagonal brace portion 61 of the anti-falling diagonal brace member 60 to rotate upward will be, and the greater the force of the diagonal brace portion 61 abutting against the side wall of the concrete beam 80, the more stable the safety belt suspension device provided by the utility model is fixed. Therefore, in actual use, the safety belt suspension device provided by the utility model has a reliable safety anti-falling effect, and can also ensure stable and reliable load-bearing for construction workers with a large weight.

[0047] In one embodiment, the first clamp 21 and the second clamp 22 respectively include a movable sleeve 30 and a fastener 40, wherein the movable sleeve 30 is mounted on the support 10 and can move along the support 10, and the locking structure 50 is used to lock the movable sleeve 30 on the support 10; the fastener 40 is mounted on the movable sleeve 30 and can adjust its position relative to the movable sleeve 30 to abut against the concrete beam 80. The first clamp 21 and the second clamp 22 can adjust their positions relative to the support 10 to adjust the distance between the first clamp 21 and the second clamp 22, and the fastener 40 adjusts its position relative to the movable sleeve 30, so as to arrange the first clamp 21 and the second clamp 22 on both sides of the concrete beam 80, and make the fasteners 40 on both sides abut against the concrete beam 80, which is conducive to conveniently and reliably installing the safety belt suspension device on the concrete beam 80.

[0048] Preferably, if Figure 1 and Figure 2 As shown, the first clamping member 21 includes two fasteners 40, and the second clamping member 22 includes one fastener 40. The two fasteners 40 of the first clamping member 21 are spaced apart vertically, and the vertical position of the fastener 40 of the second clamping member 22 is located between the two fasteners 40 of the first clamping member 21, so as to ensure that the fasteners 40 on both sides of the concrete are evenly distributed, which is conducive to the safety belt suspension device being firmly suspended on the concrete beam 80 when bearing its own load and the downward pulling force of the safety belt to avoid separation. The downward pulling force of the safety belt includes the load of the construction personnel connected to the safety belt.

[0049] In one embodiment, the support member 10 extends in the transverse direction 100 , the movable sleeve 30 can move relative to the support member 10 in the transverse direction 100 , and the fastener 40 can move relative to the movable sleeve 30 in the transverse direction 100 , so that the fasteners 40 on both sides clamp the concrete beam 80 .

[0050] Preferably, the moving sleeve 30 of the first clamping member 21 extends in a direction perpendicular to the lateral direction 100, and the moving sleeve 30 of the second clamping member 22 extends in a direction perpendicular to the lateral direction 100; the extending direction of the moving sleeve 30 of the first clamping member 21 is parallel to the extending direction of the moving sleeve 30 of the second clamping member 22. Preferably, when the safety belt suspension device is installed on the concrete beam 80, the extending direction of the moving sleeve 30 of the first clamping member 21 and the extending direction of the moving sleeve 30 of the second clamping member 22 are both vertical directions.

[0051] In one embodiment, the anti-dropping diagonal support member 60 is provided with a limiter, and the limiter is used to limit the rotation angle range of the anti-dropping diagonal support member 60 relative to the second clamping member 22. Preferably, the rotation range of the anti-dropping diagonal support member 60 is limited to: Figure 2 As shown, the angle β between the longitudinal direction of the anti-dropping diagonal brace 60 and the extension direction of the movable sleeve 30 of the second clamping member 22 satisfies 45°≤β≤90°, and the anti-dropping diagonal brace 60 can rotate relative to the second clamping member 22 within this angle range. The anti-dropping diagonal brace 60 extends along a straight line, and the extension direction of the anti-dropping diagonal brace 60 is its longitudinal direction.

[0052] Preferably, the safety belt suspension device is installed on the concrete beam 80, and after the first clamping member 21, the second clamping member 22 and the anti-falling diagonal brace member 60 are all pressed against the concrete beam 80, the angle β between the longitudinal direction of the anti-falling diagonal brace member 60 and the extension direction of the movable sleeve 30 of the second clamping member 22 satisfies 45°≤β≤80°, so as to prevent the fastener 40 of the second clamping member 22 from extending too long or too short, and to avoid the anti-falling diagonal brace member 60 from not being stressed or being unevenly stressed or being stressed too much, thereby affecting the safety of use.

[0053] The support member 10 may be a cross beam. Preferably, the cross beam has a top surface, and during installation, the top surface of the cross beam abuts against the bottom surface of the concrete beam 80.

[0054] In one embodiment, if Figure 1 and Figure 2 As shown, the locking mechanism includes a pin 51; the movable sleeve 30 is sleeved outside the support 10, the support 10 is provided with a first locking hole 11, and the movable sleeve 30 is provided with a second locking hole 31, and a spring latch 52 is provided through the aligned first locking hole 11 and the second locking hole 31 to limit the movement of the movable sleeve 30 relative to the support 10, so as to lock the movable sleeve 30 to the support 10.

[0055] The locking mechanism can have various structural forms. In another embodiment, the locking structure 50 includes a spring latch 52; the movable sleeve 30 is sleeved outside the support member 10, the support member 10 is provided with a first locking hole 11, the movable sleeve 30 is provided with a second locking hole 31, and the spring latch 52 can extend to the aligned first locking hole 11 and the second locking hole 31.

[0056] In one embodiment, if Figure 4 As shown, the support member 10 is tubular, the movable sleeve 30 is sleeved outside the support member 10, the spring latch 52 includes a latch 521 and a spring 522, the latch 521 is movably mounted on the movable sleeve 30, one end of the spring 522 abuts against the latch 521, and the other end of the spring 522 abuts against the inner wall of the movable sleeve 30, when the first locking hole 11 is aligned with the second locking hole 31, the elastic force of the spring 522 can drive the latch 521 to extend into the aligned first locking hole 11 and the second locking hole 31, so as to lock the movable sleeve 30 to the support member 10. The latch 521 is manually lifted by the latch handle on the upper part of the latch 521, and the latch 521 is pulled out from the first locking hole 11, so that the movable sleeve 30 can move relative to the support member 10. After releasing the hand, the spring 522 always applies a downward force to the latch 521. When the movable sleeve 30 is adjusted left and right, when the second locking hole 31 of the movable sleeve 30 is aligned and overlapped with the other first locking hole 11 of the support 10, the latch 521 automatically extends into the pair of aligned first locking hole 11 and second locking hole 31 under the elastic force of the spring 522 to prevent the movable sleeve 30 from shifting.

[0057] Preferably, if Figure 4 As shown, the upper portion of the side wall of the support member 10 is provided with a long slot 12 extending in the transverse direction 100, and after the latch 521 is pulled out of the first locking hole 11, the latch handle of the latch 521 can move in the long slot 12 in the transverse direction 100. The lower portion of the side wall of the support member 10 is provided with a plurality of first locking holes 11 spaced apart in the transverse direction 100. The diameters of the first locking holes 11 and the second locking holes 31 are slightly larger than the diameter of the latch 521. The support member 10 is preferably made of a seamless square steel pipe.

[0058] In one embodiment, if Figure 3 and Figure 5 As shown, the fastener 40 includes a fastening bolt 41 and a rubber leg 42. Preferably, the fastening bolt 41 and the rubber leg 42 are spherically hinged, and the angle can be adjusted within the standard flatness error of the concrete beam 80 side wall, ensuring that the rubber leg 42 can be more tightly attached to the concrete beam 80 side wall, increasing the contact area, increasing the friction, and preventing it from falling off, ensuring stable force.

[0059] The movable sleeve 30 is provided with a mounting through hole 32, which extends and penetrates in the transverse direction 100, and the diameter of the mounting through hole 32 is slightly larger than the diameter of the fastening bolt 41, and does not exceed the outer diameter of the large nut 33; the large nut 33 matches the fastening bolt 41 and is used to fix the fastening bolt 41. The large nut 33 is welded to the movable sleeve 30, and the axial direction of the large nut 33 is the transverse direction 100. The large nut 33 is welded on both sides of the movable sleeve 30 (i.e., the two ends of the mounting through hole 32) or one side.

[0060] The first clamping member 21 is connected to two fastening bolts 41 , and the upper and lower fastening bolts 41 are of unequal lengths so that the ends are staggered to prevent the handles 43 of the two fastening bolts 41 from colliding during fastening. When in use, the shorter fastening bolt 41 is tightened first, and then the longer fastening bolt 41 is tightened.

[0061] The diameter of the handle 43 is required to be smaller than the diameter of the fastening bolt 41. A through hole is drilled at the end of the fastening bolt 41. The diameter of the through hole is slightly larger than the diameter of the handle 43 and does not exceed the diameter of the small nut 44. The handle 43 is threaded at both ends and fixed with the small nut 44, so that the handle 43 can move up and down in the through hole at the end of the fastening bolt 41 without falling off, ensuring that the fastening bolt 41 can be securely installed within the adjustable range. The small nut 44 is required to match the threaded diameter size at both ends of the handle 43. The threaded parts at both ends of the handle 43 are tightened with the small nuts 44 for secure installation.

[0062] Specifically, Figure 5 As shown, the movable sleeve 30 includes a sleeve portion 301 and a support portion 302, the sleeve portion 301 is sleeved outside the support member 10, and the fastener 40 is installed on the support portion 302, that is, the sleeve portion 301 of the movable sleeve 30 is sleeved outside the support member 10; the mounting through hole 32 is provided on the support portion 302, and the extension direction of the movable sleeve 30 is the extension direction of the support portion 302.

[0063] The number of the anti-falling diagonal brace members 60 may be one or more. The second clamping member 22 may be connected to one or more anti-falling diagonal brace members 60. In one embodiment, the first clamping member 21 and the second clamping member 22 may be connected to the anti-falling diagonal brace members 60, and the anti-falling diagonal brace members 60 on the first clamping member 21 and the anti-falling diagonal brace members 60 on the second clamping member 22 may be respectively pressed against the side wall of the concrete beam. Preferably, the anti-falling diagonal brace members 60 on the first clamping member 21 and the anti-falling diagonal brace members 60 on the second clamping member 22 are symmetrically arranged. In another embodiment, as Figure 1 and Figure 2 As shown, only one anti-falling diagonal brace member 60 is provided, and is rotatably hinged to the second clamping member 22 , which is beneficial to ensure the firmness of the safety belt suspension device fixed to the concrete beam 80 .

[0064] When in use, firstly, according to the width of the concrete beam 80, the spacing between the first clamping member 21 and the second clamping member 22 on the support member 10 is roughly adjusted, so that the first clamping member 21 and the second clamping member 22 are respectively located on both sides of the concrete beam 80 and clamped, and the concrete beam 80 is centered in the middle of the support member 10 as much as possible, and the upper surface of the support member 10 is closely attached to the lower surface of the concrete beam 80; then, the first clamping member 21 and the second clamping member 22 are fixedly clamped by the locking structure 50; the diagonal bracing portion 61 of the anti-dropping diagonal bracing member 60 is required to clamp the side wall of the concrete beam 80 downward First, repeatedly tighten the two fastening bolts 41 of the first clamping member 21 in sequence, and then repeatedly tighten the fastening bolts 41 of the second clamping member 22 until it is confirmed that all are tightened without looseness. Finally, it is confirmed that the angle between the diagonal bracing portion 61 of the protruding movable sleeve 30 of the anti-falling diagonal bracing member 60 on the side of the concrete beam 80 and the extending direction of the movable sleeve 30 of the second clamping member 22 is within the range of 45 to 80 degrees, and the safety belt hanging device can fully bear its own weight and the load of the construction personnel. Then, the safety belt is hung on the lifting ring 71 before it can be put into use.

[0065] The utility model provides a safety belt hanging device for the bottom of a beam, which relates to the technical field of safety in high-altitude construction operations. In particular, when performing high-altitude operations below a concrete beam 80 with a floor slab, the safety belt hanging device can be hung below the concrete beam 80 to fix the safety belt rope and can be used within a certain range to prevent personnel from falling from a height.

[0066] The above are only several embodiments of the present invention. Those skilled in the art can make various changes or modifications to the embodiments of the present invention based on the contents disclosed in the application documents without departing from the spirit and scope of the present invention.
