Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.
Referring to fig. 1, in the prior art, a common connection manner between a hanger 10 and a precast capping beam 200 is to connect through a flexible connection member, that is, a connection rope is respectively connected to a pulling assembly 11 on the hanger 10 and a lifting lug 210 on the precast capping beam 200 to hoist the precast capping beam 200. However, in the hoisting process, it is only necessary to generally ensure that the precast capping beam 200 can be in a horizontal state in the hoisting process, so that in the existing construction site, the connecting rope is in an inclined state, and at this time, the pulling force applied to the precast capping beam 200 by the pulling assembly 11 through the connecting rope is not completely used for pulling the precast capping beam.
Referring to fig. 2, in a specific embodiment, each traction assembly 11 is provided with two first symmetrically arranged mounting locations 111 near the end of the precast capping beam 200; the side of the precast capping beam 200 close to the pulling assembly 11 is provided with four lifting lugs 210. Two adjacent lifting lugs 210 are arranged opposite to the two first installation positions 111 on the traction assembly 11, and the lifting lugs 210 are correspondingly connected with the first installation positions 111 one by one through the connecting ropes. Wherein, the connecting rope is in the slope setting in vertical direction under the tensile state. The pulling force F is not entirely converted into an effective vertical pulling force, but can be decomposed into a vertical upward pulling force Fa and a horizontal direction pulling force Fb. Wherein Fa is the effective pulling force and Fb is the useless pulling force. The presence of the pulling force Fb indicates that the hoisting is not the most efficient state.
The first embodiment is as follows:
referring to fig. 3 to 5, fig. 3 is a schematic structural diagram of a hoisting structure 100 specially used for a precast capping beam according to an embodiment of the present invention. The hoisting structure 100 dedicated to precast capping beams comprises, for example, at least two hangers 10 and at least one lifting adjustment device 20. At least two hangers 10 are combined to form a hoisting space 15, each hanger 10 is provided with a traction assembly 11, the traction assembly 11 is positioned in the hoisting space 15, and the traction assembly 11 is used for traction connection with a hoisting adjusting device 20.
The lifting adjustment device 20 is arranged in the hoisting space 15 and the lifting adjustment device 20 is located below the pulling assembly 11. Each lifting adjustment device 20 includes, for example, at least a pair of first hoist ring assemblies 21, at least a pair of second hoist ring assemblies 22, and at least one lifting adjustment body 23. Each first lifting ring assembly 21 is arranged on one side of the lifting adjusting body 23 close to the traction assembly 11; each second eye assembly 22 is provided on a side of the lifting adjustment body 23 remote from the tow assembly 11. Wherein the first lifting eye assembly 21 is connected to the corresponding traction assembly 11 in a manner such that the lifting adjustment device 20 is in a horizontal position.
In a specific embodiment, the special hoisting structure 100 for precast capping beams is provided with one hoisting adjusting device 20 and two hangers 10. Each hanger 10 is provided with a traction assembly 11; the hoist adjustment device 20 is provided with, for example, a pair of first hoist ring assemblies 21 and a pair of second hoist ring assemblies 22. In particular, each cradle 10 is fixedly arranged, i.e. the distance between two cradles 10 is maintained constant, the traction assembly 11 being able to slide on the respective cradle 10. By adjusting the distance between the traction assemblies 11, the distance between the two traction assemblies 11 is equal to the distance between the two first hoisting ring assemblies 21, that is, horizontal hoisting of the hoisting adjusting device 20 is realized, and at the moment, the traction tension of each traction assembly 11 on the corresponding first hoisting ring assembly 21 is in an optimal state, and no ineffective tension exists.
The hanger 10 in the embodiment of the present invention may also be, for example, a gantry, and certainly, the hanger is not limited to the gantry, and may also be another hoisting device according to the embodiment of the present invention. For example, the hoisting device may also be a combined structure of a hoisting frame and a crown block, the crown block is arranged on the hoisting frame, the crown block can move relatively on the hoisting frame, and the crown block hoists the hoisting adjusting device 20, so that the hoisting adjusting device 20 hoists the precast capping beam 200.
In addition, the two second hoisting ring assemblies 22 are used for hoisting the prefabricated capping beam 200, and the distance between each second hoisting ring assembly 22 is equal to the distance between the two lifting lugs 210 which are matched and connected with the prefabricated capping beam 200 on the prefabricated capping beam 200, so that the prefabricated capping beam 200 is horizontally hoisted, and similarly, no invalid tension exists, and an optimal tension state is realized. In summary, in the present embodiment, the traction assembly 11 achieves the optimal tension state for the lifting adjustment device 20; likewise, the second eye assembly 22 achieves an optimum tension for the prefabricated cap beam 200.
Preferably, at least one of the hangers 10 is a mobile hanger. The mobile crane comprises, for example, two oppositely disposed third slide rails 12, two oppositely disposed supports 13 and a cantilever beam 14. The supporting pieces 13 are in one-to-one corresponding sliding connection with the third sliding rails 12; the cantilever beam 14 is erected on the top of two oppositely arranged supports 13, the traction assembly 11 is arranged on the bottom of the cantilever beam 14, and the traction assembly 11 can slide on the cantilever beam 14 along the length direction thereof.
Example two:
referring to fig. 6, preferably, the lifting adjustment body 23 is provided with, for example, opposite first and second sides. The first side is the side, close to the traction component 11, of the lifting adjusting body 23, and each pair of first hoisting ring components 21 is arranged on the first side; the second side is the side of the lifting adjustment body 23 away from the traction assembly 11, and each pair of second lifting ring assemblies 22 is disposed on the second side. Specifically, the two first eye assemblies 21 in each pair of first eye assemblies 21 are symmetrically disposed along their lengths on the first side, and likewise, the two second eye assemblies 22 in each pair of second eye assemblies 22 are symmetrically disposed along their lengths on the second side.
Further, to improve the versatility of the lifting adjustment device 100, optimized lifting can be achieved for different sizes of objects. At least one pair of second eye assemblies 22 and/or at least one pair of first eye assemblies 21 are capable of relative movement with respect to the lifting adjustment body 23.
For example, each pair of second eye assemblies 22 includes, for example, a second eye assembly a221 and a second eye assembly b 222. The second lifting ring assembly a221 is fixedly connected to the lifting adjusting body 23, and the second lifting ring assembly b222 is movably connected to the lifting adjusting body, so that the relative distance between the second lifting ring assembly a221 and the second lifting ring assembly b222 is adjusted to meet the optimal lifting requirement for the prefabricated capping beam 200, namely, when the connecting rope is connected with the second lifting ring assembly 22 and the corresponding lifting lug 210, the prefabricated capping beam is in a vertical state.
In contrast, the connection state between each pair of the first lifting ring assemblies 21 and the traction assembly 11 is the same as the connection state between the second lifting ring set 22 and the lifting lug 210 in the above example, and is also in the optimal lifting state, which is not described herein again.
Preferably, at least one pair of first eye assemblies 21 is slidably connected to the lifting adjustment body 23. Each first eye assembly 21 includes, for example, a first slide rail 211 and a first eye 212. The first slide rail 211 is transversely and/or longitudinally arranged on the lifting adjusting body 23; the first hanging ring 212 is slidably connected to the first slide rail. When the first slide rail 211 is transversely arranged on the lifting adjusting body 23, that is, the first slide rail 211 is arranged along the length direction of the lifting adjusting body 23, the first hanging ring 212 can slide back and forth on the first slide rail 211, and thus the two first hanging rings 212 which are oppositely arranged can move close to or away from the respective first slide rail 211. Similarly, the first slide rail 211 may be longitudinally disposed on the lifting adjusting body 23, that is, the first slide rail 211 is disposed along the width direction of the lifting adjusting body 23.
Further, the two oppositely disposed first sliding rails 211 may be communicated with each other or isolated from each other.
In one embodiment, the first slide rail 211 is a limiting groove structure, the limiting groove is disposed along the length direction of the lifting adjusting body 23, and the first hanging ring 212 is provided with a limiting block connected with the limiting groove in a matching manner. The limiting groove and the limiting block can be in a mortise-tenon joint matching mode, the two matching structures are simple, disassembly or assembly is facilitated, meanwhile, in the process that the first hanging ring 212 is connected with the traction assembly 11 in a matching mode, the limiting groove structure can prevent the limiting block arranged in the limiting groove structure from being separated.
Referring to fig. 7, preferably, the first suspension ring 212 includes, for example, two suspension ring members 2121 and a first slider 2122. The first slider 2122 is connected to the first slide rail 211 in an embedded manner, and the two suspension ring elements 2121 are disposed opposite to each other and disposed on a side of the first slider 2122 away from the first slide rail 211. Specifically, the first slider 2122 includes, for example, a connecting block 2123 and a fitting block 2124. A fourth sliding groove 2125 is formed in one side of the connecting block 2123 away from the first sliding rail 211, the hanging ring piece 2121 is connected with the fourth sliding groove 2125 in a matching manner, the matching connection manner may be a mortise-tenon joint, and the hanging ring piece 2121 can slide on the fourth sliding groove 2125; the fitting block 2124 is provided on a side of the connecting block 2123 away from the eye piece 2121, and the fitting block 2124 is slidably connected to the first slide rail 211. For example, the first slide rail 211 is an arc chute, and the fitting block 2124 is an arc sphere structure slidably connected to the arc chute, that is, the arc sphere can rotate and slide in the arc chute, so that the first hanging ring 212 can rotate relative to the first slide rail 211, and meanwhile, the two opposite hanging ring pieces 2121 can slide relative to each other on the fourth chute 2125, so as to adjust the distance between the two hanging ring pieces 2121.
In contrast, the second eye assembly 22 has the same structure as the first eye assembly 21, and will not be described again.
Referring to fig. 8-9, further, the lifting adjustment device 20 includes, for example, a plurality of blanking panels 30. The shielding plates 30 are disposed on two sides of the lifting adjusting body 23, that is, the shielding plates 30 are disposed on two ends of the first slide rail 211. For example, during the process of connecting the first hanging ring assembly 21 with the pulling assembly 11 to hoist the prefabricated bent cap 200, the shielding plate 30 can limit the first hanging ring 212 from being separated from the first sliding rail 211. Wherein the shielding plate 30 can be connected to the lifting adjusting body 23 by a fastener; of course, the shielding plate 30 may be rotatably connected to the lifting adjustment body 23, and specifically, the shielding plate 30 is provided with a first connection hole 31 and a second connection hole 32, and the lifting adjustment body 23 is provided with a third connection hole 232 opposite to the first connection hole 31 and a fourth connection hole opposite to the second connection hole 32.
Wherein, the first connection hole 31, the second connection hole 32 and the third connection hole 232 may be screw holes, and the fourth connection hole is a through hole. When the shielding plate 30 is connected with the first slide rail 211 in a matching manner, the first connecting hole 31 and the third connecting hole 232 are sequentially connected through bolts, and the half-tooth bolt is sequentially connected with the second connecting hole 32 and the fourth connecting hole; when the first hanging ring 212 needs to be detached from the first slide rail 211, the bolt is loosened, so that the shielding plate 30 rotates around the half-threaded bolt, and is separated from the joint of the first slide rail 211, so that the end of the first slide rail 211 is exposed.
Of course, the connection relationship between the shielding plate 30 and the lifting adjustment body 23 may also be a sliding connection. For example, two sides of the lifting adjusting body 23 are provided with limiting sliding grooves, the limiting sliding grooves are disposed at two ends close to the first sliding rail 211, and the shielding plate 30 is slidably connected to the limiting sliding grooves, that is, when the shielding plate 30 slides in the limiting sliding grooves, the shielding plate can shield or expose corresponding ends of the first sliding rail 211.
In contrast, the embodiment of the shielding plate 30 for shielding the second eye assembly 22 is the same as the embodiment of the shielding plate 30 for shielding the first eye 212 in the above example, and thus the description thereof is omitted.

The first side is provided with at least one pair of first lifting ring assemblies 21, and the second side is provided with at least one pair of second lifting ring assemblies 22. A plurality of mounting positions 231 arranged in an array are arranged on the first side and/or the second side, and each mounting position 231 is connected with the first hanging ring assembly 21 or the second hanging ring assembly 22 in a matching manner. For example, the mounting locations 231 are a plurality of sliding grooves distributed along the width direction of the lifting adjustment body 23, each of which penetrates through opposite sides of the lifting adjustment body 23.
Of course, the mounting locations 231 may also be a plurality of sliding slots distributed along the length of the lifting adjustment body 23, and likewise, each of the sliding slots may extend through opposite sides of the lifting adjustment body 23.
Example 4:
referring to fig. 11, in the present embodiment, the lifting adjusting means 20 includes, for example, a first lifting adjusting means 24 and a second lifting adjusting means 25.
