Description

Technical Field

[0001] The utility model relates to the technical field of slings, in particular to a sling for bridge prefabricated components. Background Art

[0002] In the existing technology, when building a bridge, in some scenarios, two cranes are needed to suspend the same material. The two cranes need to be coordinated synchronously, and the ground personnel need to carefully observe whether the material is offset. At the same time, during the lifting process, personnel are prohibited from standing under the material, and can only stand around the material and keep a safe distance. Therefore, if the two cranes are not coordinated and the ground personnel do not observe carefully, the material may be seriously offset, resulting in a safety accident. To this end, we propose a hoist for bridge prefabricated components. Utility Model Content

[0028] Please refer to Figures 1 to 3 The present application provides a suspension device for a bridge prefabricated component 70 , including a beam 10 , a clamp 40 , a suspension rope, and pulley assemblies 30 located at both ends of the beam 10 .

[0029] Specifically, both ends of the beam 10 are fixedly connected with a mounting plate 20, and the mounting plate 20 is divided into a symmetrical first mounting portion 21 and a second mounting portion 22 by the beam 10. The second mounting portion 22 is located below the first mounting portion 21, and a hanging hole 21a is provided at the end of the first mounting portion 21 away from the beam 10; the pulley assembly 30 includes a fixing bar 31, a first pulley 32 and a second pulley 33, the fixing bar 31 is connected to the end of the second mounting portion 22 away from the beam 10, the first pulley 32 and the second pulley 33 are symmetrically connected to both ends of the fixing bar 31, and the first pulley 32 and the second pulley 33 are respectively connected with a first steel rope 50 and a second steel rope 60; the first steel rope 50 and the second steel rope 60 are connected to the ends away from the fixing bar 31 with a clamp 40, and the clamp 40 is used to clamp the bridge prefabricated component 70; the suspension rope passes through the hanging hole 21a and is connected to the first mounting portion 21.

[0030] For example, when hoisting prefabricated bridge components, four steel wire ropes are wound into a lifting rope, and then the two ends of the lifting rope are respectively passed through the hanging holes of the first mounting part at both ends of the beam to connect the beam, thereby facilitating the subsequent use of a lifting device to smoothly lift the clamped prefabricated bridge components as a whole to avoid shaking during the lifting process.

[0031] The hoist of the bridge pre-component 70 based on the above technical features is achieved by fixing the mounting plate 20 at both ends of the beam 10, and dividing the mounting plate 20 into a first mounting portion 21 and a second mounting portion 22, and then connecting the first pulley 32 and the second pulley 33 to the second mounting portion 22 by using the fixing bar 31, and then connecting the first steel rope 50 and the second steel rope 60 to the first pulley 32 and the second pulley 33 respectively, and then clamping the bridge pre-component 70 by using the clamp 40, and connecting the clamp 40 to the first steel rope 50 and the second steel rope 60, and finally lifting the beam 10 by using the lifting equipment, so as to realize the lifting of the bridge pre-component 70, and the lifting can be realized without the cooperation of multiple cranes, which can effectively solve the problem of serious displacement of the lifting materials, and has a simple structure and is easy to operate.

[0032] In a possible embodiment, the clamp 40 includes a clamp body 41 and a pressure block 42. The clamp body 41 is connected to one end of the first steel rope 50 or the second steel rope 60 away from the fixing bar 31. A clamping space for clamping the bridge prefabricated component 70 is formed between the pressure block 42 and the clamp body 41.

[0033] In a possible embodiment, a clamping bolt is further included. A first mounting hole is opened on the clamp body 41, and a second mounting hole is opened on the pressure block 42, which is opposite to the first mounting hole. The clamping bolt passes through the second mounting hole and the first mounting hole in sequence, so that the pressure block 42 can be adjustably connected to the clamp body 41.

[0034] Exemplarily, when the bridge pre-component 70 needs to be hoisted, the clamp body 41 and the pressure block 42 are used to clamp the steel bars of the bridge pre-component 70. At this time, the first mounting hole and the second mounting hole are aligned. Then, the clamping bolt is passed through the first mounting hole and the second mounting hole in sequence and locked to clamp the bridge pre-component 70. Then, the clamp body 41 is connected to the first steel rope 50 or the second steel rope 60. Finally, the lifting equipment is used to lift the beam 10, thereby lifting the bridge pre-component 70. The operation is convenient and the lifting steps can be simplified.

[0035] In a possible implementation, a connecting bar 43 is further included. The connecting bar 43 is arranged in a vertical direction, and one end of the connecting bar 43 is connected to the clamp body 41 , and the other end of the connecting bar 43 is connected to one end of the first steel rope 50 or the second steel rope 60 .

[0036] In a possible implementation, a connection hole 43a is provided at one end of the connection bar 43 away from the clamp body 41. Thus, by providing the connection hole 43a on the connection bar 43, one end of the first steel rope 50 or the second steel rope 60 can pass through the connection hole 43a for fastening. Since the clamp body 41 is connected to the connection bar 43, the connection between the clamp body 41 and the first steel rope 50 or the second steel rope 60 can be achieved. The structure is simple and the disassembly is convenient. The corresponding clamp body 41 can be used according to different bridge prefabricated components 70.

[0037] In a possible implementation manner, a first thread 41 a is provided on a side of the clamp body 41 facing the pressing block 42 , and a second thread 42 a is provided on a side of the pressing block 42 facing the clamp body 41 .

[0038] Exemplarily, by distributing the first thread 41a and the second thread 42a on the clamp body 41 and the pressure block 42, when the steel bars of the bridge precomponent 70 are clamped, the first thread 41a and the second thread 42a can increase the contact friction with the steel bars of the bridge precomponent 70, thereby increasing the clamping effect on the bridge precomponent 70 and further strengthening the clamping of the bridge precomponent 70.

[0039] In a possible implementation, the cross beam 10 is made of steel. Thus, the cross beam 10 made of steel can have sufficient strength to avoid breakage during the hoisting process, which poses a safety hazard.

[0040] It can be understood that the above embodiments only express the preferred implementation methods of the utility model, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the patent scope of the utility model. It should be pointed out that, for ordinary technicians in this field, without departing from the concept of the utility model, the above-mentioned technical features can be freely combined, and several deformations and improvements can be made, which all belong to the protection scope of the utility model. Therefore, all equivalent changes and modifications made to the scope of the claims of the utility model should belong to the scope covered by the claims of the utility model.
