Detailed Description
The present application is described in further detail below with reference to figures 1-2.
The embodiment of the application discloses lifting appliance for lifting bridge deck of combat readiness bridge.
Example 1
Referring to fig. 1, the lifting appliance for lifting the bridge deck of the combat readiness bridge comprises a lifting beam 1, wherein the lifting beam 1 is an I-shaped beam, and the lifting beam 1 is lifted by a lifting platform so as to be conveyed to a bridge needing to be spliced. The upper surface of the hoisting beam 1 is provided with at least two lifting blocks 11, and the two lifting blocks 11 are provided with through holes for hoisting the hoisting platform. When the hoisting platform hoists the hoisting beam 1, the stability of the hoisting beam 1 during hoisting of the hoisting beam 1 is ensured by the arrangement of the minimum two lifting blocks 11, more lifting blocks 11 can be arranged on the upper surface of the hoisting beam 1 besides the two lifting blocks 11, and after the hoisting platform is disconnected from one lifting block 11, the other lifting blocks 11 can continue to play roles of connection and hoisting.
Referring to fig. 1, a plurality of groups of lifting clamps 2 are connected to the lower surface of a lifting beam 1, each group of lifting clamps 2 is used for lifting one bridge deck assembly 3, and a plurality of bridge deck assemblies 3 are firstly assembled together before being lifted by the lifting clamps 2, wherein the assembling mode among the plurality of bridge deck assemblies 3 is a mode well known to those skilled in the art and will not be described in detail herein. When needs are handled bridge deck unit 3 to the bridge department that needs laid, at first put together a plurality of bridge deck unit 3, then through hoist and mount platform with hoist and mount 1 handling to the bridge department that needs the concatenation, a plurality of stone tongs 2 on the hoist and mount roof beam 1 will assemble bridge deck unit 3 and transport to the bridge department that needs the concatenation in the in-process that hoist and mount roof beam 1 removed to accomplish the installation to a plurality of bridge deck unit 3 simultaneously, improved the efficiency of bridge deck installation.
Referring to fig. 1, each hoisting fixture 2 comprises a hoisting block 21 connected to the lower surface of the hoisting beam 1, two hoisting holes 22 are formed in the bottom of one side wall of the hoisting block 21 perpendicular to the hoisting beam 1 and penetrate inwards, a hoisting ring 23 is arranged in each hoisting hole 22, two connecting pieces 24 are sleeved in each hoisting ring 23, and each connecting piece 24 is a rod-shaped material, a rope-shaped material or a chain-shaped material. One end of each connecting member 24 remote from the lifting ring 23 is provided with a lifting hook 25 for lifting the deck assembly 3. When the bridge deck assembly 3 is lifted by the hook 25, a ring part for the hook 25 to hook may be fixedly provided on the bridge deck assembly 3, or a lifting hole 31 for the hook 25 to hook may be provided on the bridge deck, preferably, the lifting hole 31 for the hook 25 to hook is provided on the bridge deck. When offering the lifting hole 31 that supplies the lifting hook 25 to hook on the bridge floor, every lifting hole 31 inner wall still communicates the water pipe that leads with the lower surface intercommunication of bridge floor subassembly 3, and lifting hole 31 on every bridge floor subassembly 3 all is provided with four, and four lifting holes 31 set up respectively in the four corners department of bridge floor subassembly 3 upper surface and all the same with the distance of bridge floor subassembly 3 upper surface center department.
When the bridge deck assembly 3 needs to be hoisted by the hoisting clamp 2, the hook part of the hook 25 is hung on the bridge deck assembly 3, and the motion of the hoisting beam 1 drives the hoisting block 21, the hoisting ring 23 and the connecting piece 24, so that the connecting piece 24 drives the hook 25 to hoist the bridge deck assembly 3. The vertical distances from the tops of the four connecting pieces 24 to the center of the upper surface of the bridge deck assembly 3 are the same, so that the lengths of the four connecting pieces 24 are the same, the four connecting pieces 24 are in a stressed state when the bridge deck assembly 3 is lifted, and the probability that a single connecting piece 24 is damaged due to uneven stress is reduced.
Referring to figure 1, the distance between each two adjacent sets of lifting clamps 2 is the distance between the centre positions of two adjacent deck assemblies 3 after completion of erection. After the assembled bridge deck assemblies 3 are hoisted by the hoisting fixtures 2, the distance between two groups of adjacent hoisting fixtures 2 is the distance between the central positions of the two adjacent bridge deck assemblies 3, and each group of hoisting fixtures 2 is positioned above the central position of one bridge deck assembly 3, so that the hoisting capacity of the hoisting fixtures 2 is guaranteed.

When the length of the connecting piece 24 is not less than 1.5 times of the distance from the lifting hole 31 to the center of the upper surface of the bridge deck assembly 3, the angle between the connecting piece 24 and the bridge deck assembly 3 is greater than 45 degrees, and when the angle between the connecting piece 24 and the bridge deck assembly 3 is too small, the component force of the pulling force of the connecting piece 24 in the vertical direction is reduced, so that the connecting piece 24 is required to bear larger pulling force when the bridge deck assembly 3 is pulled up, and the probability that the connecting piece 24 is damaged or even broken is increased.
The implementation principle of the embodiment 1 is as follows: when need with bridge deck assembly 3 handling to the bridge department that needs to lay, at first put together a plurality of bridge deck assembly 3, at first hang on bridge deck assembly 3 through the hook portion with lifting hook 25, the motion of hoist and mount roof beam 1 drives the motion of taking hoist and mount piece 21, rings 23 and connecting piece 24 to make connecting piece 24 drive lifting hook 25 and get up bridge deck assembly 3 hoist and handle bridge deck assembly 3 to the bridge department that needs to lay, improved the efficiency of bridge deck installation. In the hoisting process, four connecting pieces 24 are placed in each hoisting clamp 2 and are in a stressed state, so that the probability that a single connecting piece 24 is damaged due to uneven stress is reduced.
Example 2
Referring to fig. 2 and 3, the present embodiment is different from embodiment 1 in that:
a connecting block 26 is arranged between the hoisting block 21 and the lower surface of the hoisting beam 1, wherein the connection form between the hoisting block 21 and the connecting block 26 is a detachable connection form such as bolt connection, clamping connection, insertion connection and the like, and the bolt connection form is preferred here. When the hoisting block 21 is connected with the connecting block 26 through the bolt, the connecting plate 211 is fixedly connected to the upper surface of the hoisting block 21, and then the connecting plate 211 is connected with the connecting block 26 through the bolt, so that the detachable connection mode between the hoisting block 21 and the connecting block 26 is realized. The connecting block 26 and the vertical side wall of the length direction of the hoisting beam 1 are provided with an insertion hole 261 for sliding insertion of the bottom plate of the hoisting beam 1, the section of the insertion hole 261 is in a T-shaped arrangement, and the upper surface of the connecting block 26 is provided with a fastening bolt 262 for fixing the connecting block 26 on the hoisting beam 1.
The connecting block 26 can slide along the bottom plate of the hoisting beam 1, so that the position of the hoisting block 21 on the hoisting beam 1 is adjusted, and after the position of the connecting block 26 on the hoisting beam 1 is adjusted, the connecting block 26 is fixed on the hoisting beam 1 through the abutting bolt 262. When the hoisting block 21 is damaged, the detachable connection between the hoisting block 21 and the connecting block 26 facilitates the replacement of the hoisting block 21. The bolted connection between the connection plate 211 and the connection block 26 facilitates the removal of the lifting block 21.
