Description

Technical Field

[0001] The utility model relates to the technical field of prefabricated T-beam transportation, and in particular to a bridge T-beam hoisting protection device. Background Art

[0002] A T-beam refers to a beam with a T-shaped cross section, which is equivalent to the concrete in the tensile area of ​​a rectangular beam that does not contribute to the bending strength being dug out. The parts on both sides of the T-beam are called flanges, and the middle part is called beam ribs (or webs). When applied, multiple groups of T-beams need to be spliced ​​together. The existing method of splicing T-beams is to hoist and splice the T-beams by crane. The conventional method of hoisting a T-beam is to pass the ring tied with a steel wire rope through the reserved hole on the upper wing of the T-beam, then bypass it from the bottom of the prefabricated T-beam, and then pass it out from the reserved hole on the other side of the upper wing of the prefabricated T-beam. Finally, the rings at both ends of the steel wire rope are hung on the hook of the crane in a bottom-covering manner, and then the hoisting can begin. However, the dead weight of the T-beam is large, and when hoisting the T-beam, the steel wire rope will constantly rub against the bottom of the T-beam, which can easily cause damage to the bottom of the T-beam.

[0003] The existing Chinese patent document with the announcement number CN210366612U discloses a wire rope hoisting protective device, which is composed of a component corner guard and a wire rope guard plate. The component corner guard is welded with a wire rope guard plate, the component corner guard has an L-shaped cross section, and the wire rope guard plate has a C-shaped cross section; one end of the wire rope guard plate is fixedly welded to the vertical plate of the component corner guard, and the other end of the wire rope guard plate is fixedly welded to the horizontal plate of the component corner guard; the right angle of the component corner guard is in contact and connected with the middle part of the inner surface of the wire rope guard plate. The device of the above patent document can play a good protective role for the T-beam to be hoisted through the component corner guard and the wire rope guard plate during the hoisting operation.

[0004] However, when the device in the above patent document is used to hoist the T-beam, the pressure on the corner guard of the component will be transmitted to the wire rope guard plate, and the force points of the wire rope guard plate are the three points in contact with the corner guard of the component. Therefore, the force on the single point of the wire rope guard plate is relatively large, especially the contact connection point between the right angle of the corner guard of the component and the middle part of the inner surface of the wire rope guard plate, which can easily cause the wire rope guard plate to bend, thereby easily causing safety hazards. Utility Model Content

[0005] In view of the deficiencies in the prior art, the purpose of the utility model is to provide a bridge T-beam lifting protection device, in which a reinforcement member is arranged between the guard plate and the support member, which can evenly transfer the force exerted on the guard plate to the support member, reducing the possibility of bending of the support member, thereby reducing safety hazards.

[0006] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a bridge T-beam lifting protection device, including a guard plate and a support member, the cross-section of the guard plate is L-shaped, one end of the support member is fixedly connected to the vertical plate of the guard plate, and the other end of the support member is fixedly connected to the horizontal plate of the guard plate, a gap is left between the guard plate and the support member, and a reinforcement member is arranged in the gap.

[0007] The working principle of the utility model is as follows: through the setting of the reinforcement, after the guard plate is subjected to the pressure of the T-beam, the pressure will be transferred to the reinforcement, the reinforcement will be deformed, and part of the pressure will be absorbed. The reinforcement will then transfer the remaining pressure to the support. After the reinforcement is deformed, the contact area with the support becomes larger, which can make the force on the support more uniform, thereby reducing the possibility of bending of the support.

[0008] Furthermore, the cross section of the support member is L-shaped, and the corners of the support member are chamfered.

[0009] Furthermore, the cross section of the support is a major arc, the guard plate is arranged in the support, and the vertical plate of the guard plate is fixedly installed at one end of the major arc, and the horizontal plate of the guard plate is fixedly installed at the other end of the major arc.

[0010] Furthermore, the cross section of the reinforcement is rectangular.

[0011] Furthermore, the cross section of the reinforcement is annular.

[0012] Furthermore, the number of reinforcements is greater than or equal to 1, the side walls of the reinforcements abut against the side walls of the guard plate on the side close to the support member, or / and the side walls of the support member on the side close to the guard plate, and any two adjacent reinforcements abut against each other.

[0013] Furthermore, a limiting member is fixedly mounted on the side wall of the support member away from the guard plate.

[0014] Furthermore, a pad is provided on the surface of the guard plate away from the support member.

[0015] The beneficial effects of the utility model are:

[0016] 1. By setting the reinforcement, not only can part of the pressure on the guard plate be absorbed, but also the force on the support can be made more uniform, thereby reducing the possibility of bending of the support.

[0017] 2. The bottom of the T-beam can be protected by the coordinated arrangement of the guard plate, the support member and the reinforcement member, so as to avoid direct contact between the wire rope and the bottom of the T-beam, thereby reducing the wear of the bottom of the T-beam. The support member in the utility model can also reduce the wear of the wire rope, extend the service life of the wire rope, reduce the possibility of wire rope breakage, and thus reduce the occurrence of safety accidents.

[0018] 3. By setting the limiter, the wire rope can be limited to avoid displacement of the wire rope when lifting the T-beam. BRIEF DESCRIPTION OF THE DRAWINGS

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

In addition, the terms "first", "second", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0029] The following is a description of some embodiments of the present invention in conjunction with the accompanying drawings:

[0030] like Figure 1-Figure 5 As shown, the utility model proposes a bridge T-beam lifting protection device, including a guard plate 1 and a support member 2, the cross section of the guard plate 1 is L-shaped, one end of the support member 2 is fixedly connected to the vertical plate of the guard plate 1, and the other end of the support member 2 is fixedly connected to the horizontal plate of the guard plate 1, and a gap is left between the guard plate 1 and the support member 2, and a reinforcement member 3 is arranged in the gap.

[0031] The guard plate 1 is welded on the support 2, and the reinforcement 3 is welded between the guard plate 1 and the support 2. The device is set at the corner of the bottom of the T beam 6. The L-shaped guard plate 1 and the surfaces on both sides of the corner of the bottom of the T beam 6 are against each other, and the wire rope 7 is sleeved outside the support 2. When the T beam 6 is hoisted, the guard plate 1 will transfer the pressure to the reinforcement 3 after being subjected to the pressure of the T beam 6. The reinforcement 3 will deform and absorb part of the pressure. The reinforcement 3 will then transfer the remaining part of the pressure to the support 2. After the reinforcement 3 is deformed, the contact area with the support 2 becomes larger, which can make the force on the support 2 more uniform, thereby reducing the possibility of the support 2 bending.

[0032] Through this device, the direct contact between the steel wire rope 7 and the bottom of the T-beam 6 can be avoided, which can reduce the wear of the bottom of the T-beam 6 and also reduce the wear of the steel wire rope 7, thereby extending the service life of the steel wire rope 7.

[0033] Furthermore, if Figure 1 As shown, the cross section of the support member 2 is L-shaped, and the corners of the support member 2 are chamfered, and the cross section of the reinforcement member 3 is rectangular.

[0034] It is sufficient to ensure that there is a gap between the support member 2 and the guard plate 1 for inserting the reinforcement member 3. The support member 2 is a 40mm*4mm angle steel, which is easy to obtain.

[0035] Furthermore, the cross section of the support member 2 may also be a major arc, the guard plate 1 is arranged in the support member 2, and the vertical plate of the guard plate 1 is welded at one end of the major arc, and the horizontal plate of the guard plate 1 is welded at the other end of the major arc.

[0036] The support member 2 is a steel pipe with an inner diameter of 80 mm and a wall thickness of 4 mm. An opening of one quarter of the minor arc is opened on the steel pipe, and the cross section of the remaining part is three quarters of the major arc, thereby forming a C-shaped support member 2, and the guard plate 1 is arranged at the opening of the steel pipe. Through the arrangement of the support member 2, when hoisting the T-beam 6, the contact area between the steel wire rope 7 and the support member 2 is larger, and the force of the support member 2 can be more uniform, thereby further reducing the possibility of the support member 2 being bent.

[0037] Furthermore, if Figure 2 As shown, the number of reinforcement members 3 is greater than or equal to one, and the side walls of the reinforcement members 3 abut against the side walls of the guard plate 1 close to the support member 2, or / and the side walls of the support member 2 close to the guard plate 1, and any two adjacent reinforcement members 3 abut against each other.

[0038] The number of reinforcement members 3 can be one, two, three, etc., and three are preferred here. The reinforcement members 3 on both sides are against the guard plate 1 and the support member 2, the middle reinforcement member 3 is against the reinforcement members 3 on both sides, and the middle reinforcement member 3 is against the support member 2. After the guard plate 1 is subjected to pressure, the pressure is transmitted to the reinforcement member 3, and the reinforcement members 3 on both sides are preferentially subjected to force to produce deformation and squeeze the middle reinforcement member 3. At this time, the three reinforcement members 3 are all subjected to force to produce deformation and absorb part of the pressure. The three reinforcement members 3 then transfer the remaining part of the pressure to the support member 2. After the deformation of the reinforcement member, the contact area with the support member 2 becomes larger, which can make the force on the support member 2 more uniform, thereby reducing the possibility of bending of the support member 2.

[0039] Furthermore, the cross section of the reinforcement member 3 is annular.

[0040] The shape of the reinforcement 3 can be rectangular, circular, annular, trapezoidal, etc., as long as the reinforcement 3 is in contact with the guard plate 1 and the support 2. Here, it is preferably annular, and the reinforcement 3 is a steel pipe with an outer diameter of 16 mm and a wall thickness of 3 mm. When the three reinforcements 3 are in contact with each other, the reinforcements 3 on both sides are in contact with the guard plate 1 and the support 2. By setting the annular reinforcement 3, the pressure transmitted by the guard plate 1 can be better absorbed, and the pressure can be transmitted to the support 2 more evenly, so that the force on the support 2 is more even, and the possibility of bending of the support 2 is further reduced.

[0041] Furthermore, if Figure 3 As shown, a limiting member 4 is fixedly mounted on the side wall of the support member 2 away from the guard plate 1 .

[0042] The limiting member 4 is welded on the supporting member 2 . By setting the limiting member 4 , the steel wire rope 7 can be limited, thereby reducing the possibility of displacement of the steel wire rope 7 when the T-beam 6 is hoisted.

[0043] The number of limit members 4 is determined according to the number of installed steel wire ropes 7, and a gap for placing the steel wire ropes 7 is formed between two adjacent limit members 4. Through such an arrangement, both sides of the steel wire ropes 7 can be limited to avoid displacement of the steel wire ropes 7 when hoisting the T-beam 6.

[0044] Furthermore, if Figure 4 As shown, a pad 5 is provided on the surface of the guard plate 1 away from the support member 2 .

[0045] The pad 5 can be made of resin, rubber and other materials, preferably rubber. By setting the pad 5, the service life of the guard plate 1 can be extended, and the possibility of relative sliding between the guard plate 1 and the T-beam 6 when hoisting the T-beam 6 can be reduced.
