Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of arch bridges, in particular to a sling anti-slip device. Background Art
[0002] In recent years, with the rapid development of my country's economic construction, the level of bridge construction has developed by leaps and bounds, and the types of bridges have become increasingly diverse. Truss arch bridge is a special bridge design that combines the characteristics of truss structure and arch bridge structure and is widely used in practical engineering.
[0003] At present, many truss arch bridges are facing upgrading and reconstruction. During the replacement of the hanger, most of them use temporary hoisting systems to convert the cable force of the hanger. The upper structure of the temporary hoisting system mostly uses arch rib clamps. Due to the different positions of the anchor points on the hanger on the arch rib, the arch rib slopes are different, resulting in the continuous change of the sliding force between the clamp and the arch rib. The anti-slip ability of the clamp is provided by the torque of the high-strength bolts of the clamp. When the maximum static friction between the clamp and the arch ring cannot resist the sliding force of the clamp under the stress condition of the temporary hoisting system, the clamp will be displaced along the arch rib, which will cause safety hazards to the bridge structure during construction. Utility Model Content
[0004] In view of the defects existing in the prior art, the present application provides a hoisting anti-slip device, which can solve the technical problem of the hoisting system in the prior art sliding along the arch rib during the process of replacing the suspension rod.
[0005] In a first aspect, an embodiment of the present application provides a scooping anti-slip device, comprising:

Both ends of the limited distribution beam are provided with grooves, the size of the grooves is adapted to the radius of the arch rib webs, and the limited distribution beam is adjacent to the second arch rib;
[0008] There are two safety steel belts, which are arranged in parallel between the first arch rib and the second arch rib. One end of the safety steel belt is connected to the clamping part through a fixing member, and the other end is connected to the limiting distribution beam through a fixing member.
[0009] In the embodiment of the present application, the clamping part is connected to the first arch rib, the limit distribution beam is connected to the second arch rib, and the clamping part and the limit distribution beam are connected by a safety steel belt, so that the clamping part and the limit distribution beam are firmly connected, preventing the clamping part from being displaced along the first arch rib during the replacement of the hanger, reducing safety hazards during the construction process, and meeting the anti-slip requirements of the clamping part during the replacement of the hanger.
[0010] In combination with the first aspect, in one embodiment, the fixing member includes:

[0014] In the embodiment of the present application, since the safety steel belt needs to be fixed to the clamping part and the limit distribution beam respectively, and the safety steel belt is a strip-shaped steel structure, directly fixing the safety steel belt to the clamping part and the limit distribution beam respectively is not conducive to the mutual fixation of the three.

[0015] In combination with the first aspect, in one embodiment, a plurality of through holes are provided at both ends of the safety steel belt, and the two ends of the safety steel belt are respectively fixed to the first ear plate and the second ear plate via pins passing through the through holes.

Multiple through holes can adjust the working length of the safety steel belt to adapt to different distances between the clamping part and the limit distribution beam. In addition, the safety steel belt can also freely adjust the angle to adapt to the slope change of the first arch rib.
[0017] In combination with the first aspect, in one implementation, the two first ear plates are fixed to both ends of the clamping portion by welding.
[0018] In the embodiment of the present application, since the safety steel belt is connected to the clamping part through the first ear plate, the first ear plate and the clamping part need to be firmly fixed, and the two first ear plates are fixed to the two ends of the clamping part by welding, so that the two first ear plates are firmly fixed to the two ends of the clamping part to prevent the first ear plate from falling off during the construction process and reduce the probability of safety accidents.
[0019] In combination with the first aspect, in one implementation, the two second ear plates are fixed to both ends of the position-limiting distribution beam by welding.
[0020] In the embodiment of the present application, since the safety steel belt is connected to the limit distribution beam through the second ear plate, the second ear plate and the limit distribution beam need to be firmly fixed. The two second ear plates are fixed to the two ends of the limit distribution beam by welding, so that the two second ear plates are firmly fixed to the two ends of the limit distribution beam to prevent the second ear plates from falling off during the construction process and reduce the probability of safety accidents.
[0021] In combination with the first aspect, in one embodiment, it further includes a pad, and the pad is located at the connection between the two ends of the limiting distribution beam and the arch rib web.
[0022] In the embodiment of the present application, since the two ends of the limited distribution beam are located on the two arch rib webs by clamping, there will be a certain friction at the connection between the two ends of the limited distribution beam and the arch rib webs.

[0023] In combination with the first aspect, in one embodiment, the copying mat is a hardwood board or a rubber board.
[0024] In the embodiment of the present application, since there will be a certain amount of friction at the connection between the two ends of the limiting distribution beam and the arch rib web, wear-resistant material is provided at the connection between the two ends of the limiting distribution beam and the arch rib web. By using hardwood boards or rubber boards as pads, the friction at the connection between the two ends of the limiting distribution beam and the arch rib web is reduced, thereby reducing the damage to the two arch rib webs.
[0025] In combination with the first aspect, in one embodiment, the clamping portion includes a clamp and a top plate fixed above the clamp, the clamp is clamped on the circumferential outer surface of the first arch rib, and the top plate is connected to the safety steel belt.
[0026] In the embodiment of the present application, since the first arch rib is usually designed to be an arc or an ellipse, a clamp is provided so that the first arch rib can be clamped and the top plate is connected to the safety steel belt, so that the clamping part is firmly connected.
[0027] In combination with the first aspect, in one implementation, the position-limiting distribution beam is an assembly of steel sections or an assembly of steel plates.

[0037] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.
[0038] An embodiment of the present application provides an anti-slip device for a sling, which can solve the technical problem in the prior art that the sling system slides along the arch rib during the process of replacing the suspension rod.
[0039] like Figure 1 and Figure 2 As shown, the present application provides an embodiment of a scooping anti-slip device, comprising: a clamping portion 3, a limiting distribution beam 5 and a safety steel belt 4, wherein the clamping portion 3 is clamped on the outer surface of the first arch rib 7 in the circumferential direction. The limiting distribution beam 5 is arranged along the transverse bridge direction, and the two ends of the limiting distribution beam 5 are respectively connected to two arch rib webs 9 arranged in parallel. Both ends of the limiting distribution beam 5 are provided with grooves, and the size of the grooves is adapted to the radius of the arch rib webs 9. The grooves at both ends of the limiting distribution beam 5 are respectively clamped to the two arch rib webs 9, and the limiting distribution beam 5 is adjacent to the second arch rib 8. There are two safety steel belts 4, and the two safety steel belts 4 are arranged in parallel between the first arch rib 7 and the second arch rib 8. One end of the safety steel belt 4 is connected to the clamping portion 3 through a fixing member, and the other end is connected to the limiting distribution beam 5 through a fixing member.
[0040] It should be noted that the first arch rib 7 and the second arch rib 8 are arranged in parallel along the longitudinal direction of the bridge, a plurality of arch rib web members 9 are provided on the same side of the first arch rib 7 and the second arch rib 8, the plurality of arch rib web members 9 are arranged obliquely, and the arch rib web members 9 on both sides are arranged in parallel.
[0041] In the embodiment of the present application, the clamping part 3 is connected to the first arch rib 7, the limiting distribution beam 5 is connected to the second arch rib 8, and the clamping part 3 and the limiting distribution beam 5 are connected by a safety steel belt 4, so that the clamping part 3 and the limiting distribution beam 5 are firmly connected to prevent the clamping part 3 from being displaced along the first arch rib 7 during the replacement of the hanger, thereby reducing the safety hazards during the construction process and meeting the anti-slip requirements of the clamping part 3 during the replacement of the hanger.
[0042] like Figure 1 and Figure 2 As shown, in some embodiments, the fixing member includes: two first ear plates 1 and two second ear plates 6, the two first ear plates 1 are arranged along the transverse bridge direction and are respectively fixed to the two ends of the clamping part 3. The two second ear plates 6 are arranged along the transverse bridge direction and are respectively fixed to the two ends of the limit distribution beam 5. The first ear plate 1 and the second ear plate 6 located on the same side of the arch rib web 9 are respectively connected to the two ends of the insurance steel belt 4. Since the insurance steel belt 4 needs to be fixed to the clamping part 3 and the limit distribution beam 5 respectively, and the insurance steel belt 4 is a belt-shaped steel structure, directly fixing the insurance steel belt 4 to the clamping part 3 and the limit distribution beam 5 respectively is not conducive to the mutual fixation between the three. By setting the two first ear plates 1, the fixation between the insurance steel belt 4 and the clamping part 3 is facilitated, and by setting the second ear plate 6, the fixation between the insurance steel belt 4 and the limit distribution beam 5 is facilitated.
[0043] Furthermore, the two ends of the above-mentioned insurance steel belt 4 are provided with a plurality of through holes, and the two ends of the insurance steel belt 4 are respectively fixed to the first ear plate 1 and the second ear plate 6 through the pins 2 passing through the through holes. Since the first ear plate 1 and the second ear plate 6 are both provided with through holes, by providing through holes at both ends of the insurance steel belt 4, the insurance steel belt 4 and the first ear plate 1 are fixed through the pins 2 passing through the through holes, and the insurance steel belt 4 and the first ear plate 1 are fixed through the pins 2 passing through the through holes. The plurality of through holes can adjust the working length of the insurance steel belt 4 to adapt to the different distances between the clamping portion 3 and the limiting distribution beam 5. In addition, the insurance steel belt 4 can also freely adjust the angle to adapt to the slope change of the first arch rib 7.
[0044] In some embodiments, the two first ear plates 1 are fixed to both ends of the clamping portion 3 by welding. Since the safety steel belt 4 is connected to the clamping portion 3 through the first ear plate 1, the first ear plate 1 and the clamping portion 3 need to be firmly fixed. The two first ear plates 1 are fixed to both ends of the clamping portion 3 by welding, so that the two first ear plates 1 are firmly fixed to both ends of the clamping portion 3, preventing the first ear plates 1 from falling off during the construction process, and reducing the probability of safety accidents.
[0045] In some embodiments, the two second ear plates 6 are fixed to the ends of the position-limiting distribution beam 5 by welding. Since the safety steel belt 4 is connected to the position-limiting distribution beam 5 by the second ear plates 6, the second ear plates 6 and the position-limiting distribution beam 5 need to be firmly fixed. The two second ear plates 6 are fixed to the ends of the position-limiting distribution beam 5 by welding, so that the two second ear plates 6 are firmly fixed to the ends of the position-limiting distribution beam 5, preventing the second ear plates 6 from falling off during the construction process, and reducing the probability of safety accidents.
[0046] In some embodiments, the anti-slip device further includes a pad (not shown in the figure), which is located at the connection between the two ends of the limited distribution beam 5 and the arch rib web 9. Since the two ends of the limited distribution beam 5 are located on the two arch rib webs 9 in a clamping form, there will be a certain friction at the connection between the two ends of the limited distribution beam 5 and the arch rib web 9. By providing the pad, a buffering effect can be played, reducing the friction at the connection between the two ends of the limited distribution beam 5 and the arch rib web 9, and reducing the damage to the two arch rib webs 9.
[0047] Preferably, the above-mentioned pad is a hardwood board or a rubber board. Since there is a certain friction at the connection between the two ends of the limited distribution beam 5 and the arch rib web 9, wear-resistant materials are set at the connection between the two ends of the limited distribution beam 5 and the arch rib web 9. By using the pad as a hardwood board or a rubber board, the friction at the connection between the two ends of the limited distribution beam 5 and the arch rib web 9 is reduced, and the damage to the two arch rib webs 9 is reduced.
[0048] like Figure 2As shown, in some embodiments, the clamping portion 3 includes a clamp 31 and a top plate 32 fixed above the clamp 31, the clamp 31 is clamped on the outer surface of the first arch rib 7 in the circumferential direction, and the top plate 32 is connected to the safety steel belt 4. Since the first arch rib 7 is usually designed to be an arc or an ellipse, the first arch rib 7 can be clamped by providing the clamp 31, and the top plate 32 is connected to the safety steel belt 4, so that the clamping portion 3 is firmly connected.
[0049] In some embodiments, the above-mentioned limited distribution beam 5 is an assembly of steel sections or steel plates. Since the limited distribution beam 5 needs to meet certain rigidity and strength during the construction process, by setting the limited distribution beam 5 as an assembly of steel sections or steel plates, the rigidity and strength required during the construction process can be met, and steel sections or steel plates are widely available, easy to obtain, and cheap.
[0050] In some embodiments, the safety steel belt 4 is a steel plate. Since the safety steel belt 4 needs to meet certain rigidity and strength during the construction process, by setting the safety steel belt 4 as a steel plate, the rigidity and strength required during the construction process can be met, and the steel plate is widely available, easy to obtain, and cheap.
[0051] Secondly, the present application provides an embodiment of the use of an anti-slip device for hoisting. When in use, the clamping part 3 is first clamped on the circumferential outer surface of the first arch rib 7, and the grooves at both ends of the limiting distribution beam 5 are respectively clamped on the two parallel arch rib webs 9, and then along one side of the first arch rib 7 and the second arch rib 8, the two ends of the safety steel belt 4 are respectively connected to the clamping part 3 and the limiting distribution beam 5 through fixings, and on the other side, the two ends of the safety steel belt 4 are respectively connected to the clamping part 3 and the limiting distribution beam 5 through fixings.
[0052] In summary, the present application connects the clamping part 3 to the first arch rib 7, the limiting distribution beam 5 to two parallel arch rib webs 9, and the limiting distribution beam 5 is adjacent to the second arch rib 8, and the clamping part 3 and the limiting distribution beam 5 are connected by a safety steel belt 4, so that the clamping part 3 and the limiting distribution beam 5 are firmly connected, preventing the clamping part 3 from being displaced along the first arch rib 7 during the replacement of the hanger, reducing safety hazards during the construction process, and meeting the anti-slip requirements of the clamping part 3 during the replacement of the hanger.
