DETAILED DESCRIPTION

[0031] like Figure 1 to Figure 7 As shown, a segment quick splicing lifting device of the present invention is arranged on the lifting rope of the lifting equipment, including at least one group of clamping components, the clamping component includes an inverted U-shaped mounting frame 4, a slide rail 5 is arranged on the inner side of the closed end of the U-shaped mounting frame 4, the slide rail 5 is arranged along the length direction of the U-shaped mounting frame 4, and sliders 6 are symmetrically arranged on the slide rail 5. One end of two sliders 6 are slidably connected to the slide rail 5, and an L-shaped clamping plate 7 is fixedly arranged on the other end arranged opposite to the one end slidably connected to the slider 6. The transverse direction of the L-shaped clamping plate 7 The end is arranged toward the middle of the slide rail 5, and the first linear drive element 8 is arranged on both side surfaces of the U-shaped mounting frame 4. The linear telescopic element is a hydraulic rod or a linear push rod. The first linear drive element 8 is fixed on the U-shaped mounting frame 4, and the output end of the first linear drive element 8 passes through the U-shaped mounting frame 4 and is fixed on the slider 6. Connecting rods 9 are symmetrically arranged on the two sliders 6, one end of the connecting rod 9 is rotatably connected to the slider 6, and a pressure block 10 is arranged on the other end of the connecting rod 9, and the other end of the connecting rod 9 is rotatably connected to the side of the pressure block 10.

[0032] The working principle of the above technical solution is:

[0033] First, the first linear element is controlled to retract, driving the slider 6 to move toward the end of the U-shaped mounting frame 4, that is, the two L-shaped clamping plates 7 are moved to the outermost position, and then move downward from the top of the lifting segment 2, so that the lifting segment 2 is located between the two L-shaped clamping plates 7, and then the first linear element is controlled to extend, so that the L-shaped clamping plates 7 clamp the two side surfaces of the segment, and the lateral ends of the L-shaped clamping plates 7 are located below the lower surface of the lifting segment 2 (the lifting segment 2 is placed on the sleepers, that is, there is a gap between the lifting segment 2 and the ground). In the process of clamping by the L-shaped clamping plates 7, since the two sliders 6 move toward the middle, that is, under the action of the connecting rod 9, the pressing block 10 will move downward and tightly contact the upper surface of the lifting segment 2, and then in the process of clamping, the upper surface, lower surface and two side surfaces of the lifting segment 2 are all limited, so that the lifting segment 2 can be tightly clamped and limited.

[0034] In one feasible manner, the connecting rod 9 is a telescopic rod, and a plurality of evenly arranged rubber strips 11 are provided on a surface on which the pressure block 10 is set downwardly, and the rubber strips 11 are fixed on the surface on which the pressure block 10 is set downwardly. The setting of the telescopic rod can adjust the length of the connecting rod 9, thereby changing the downward movement distance of the pressure block 10 when the slider 6 moves, thereby matching the lifting segments 2 of different heights and widths. At the same time, the setting of the rubber strips 11 can enhance the anti-slip effect while compensating for the movement of the slider 6 to a certain extent, which can be understood as avoiding the situation where the L-shaped clamping plate 7 has not yet clamped the side of the lifting segment 2 when the pressure block 10 is in contact with the surface of the lifting segment 2.

[0035] In one practicable manner, it also includes an inclination adjustment component, which includes three fixed ear plates 12, which are evenly arranged on the outer side of the closed end of the U-shaped mounting frame 4, and a first screw 13 and a second screw 14 are respectively arranged between two adjacent fixed ear plates 12, and both ends of the first screw 13 and the second screw 14 are respectively rotatably connected to the fixed ear plates 12, and the fixed ear plates 12 at the two end positions are respectively provided with a rotating drive element 16, and the rotating drive element 16 is a rotating motor, and the rotating drive element 16 is fixed On the fixed ear plate 12, the output ends of the two rotating drive elements 16 are respectively fixedly connected to the first screw rod 13 and the second screw rod 14, the first screw rod 13 and the second screw rod 14 are each provided with a threaded block 25, one end of the threaded block 25 is slidably abutted on the outer side surface of the closed end of the U-shaped mounting frame 4, and the upper surfaces of the two threaded blocks 25 are each provided with a hanging ear 17, one end of the two hanging ears 17 is fixedly connected to the threaded block 25, and the other end of the two hanging ears 17 is provided with a hanging rope 18, and the two ends of the hanging rope 18 are respectively fixedly connected to the two hanging ears 17.

[0036] The working principle of the above technical solution is:

[0037] When the hoisting segment 2 after clamping needs to be spliced, its inclination needs to be adjusted (the inclination here does not refer to the height difference between the two ends of the segment, but refers to the angle of rotation along the axis of the hoisting segment 2. For example, the hoisting segment 2 set inwards, because the method of adjusting the height difference between the two ends is simple, no more details are given here). Since the hoisting rope is fixed to the middle of the hanging rope 18, that is, the lengths of the hanging ropes 18 at both ends are the same, the upper surface of the hoisting segment 2 is in a horizontal state after being hoisted. Therefore, when adjustment is needed, it is only necessary to control the movement of the rotating motor. It can drive the threaded block 25 to move, that is, change the connection point position at one end of the hanging rope 18, so that the lifting segment 2 can have an inclination angle, and then match the inclination angle required for splicing. The specific explanation is: the movement of the threaded block 25 will cause the connection point position between the lifting segment 2 to change, and the change in the connection point position will cause the center of gravity of the lifting segment 2 to change during lifting. The change in the center of gravity of the lifting segment 2 will cause the lifting segment 2 to rotate and have an inclination angle. That is, this method can quickly adjust the inclination angle of the lifting segment 2, thereby improving the efficiency of lifting and splicing of the lifting segment 2.

[0038] In one feasible manner, a light rod 15 is symmetrically provided between the two fixed ear plates 12 at the end, and the two ends of the light rod 15 are respectively fixedly connected to the fixed ear plates 12, and the threaded block 25 is slidably connected to the two light rods 15. The setting of the light rod 15 can improve the movement effect and stability of the threaded block 25, and at the same time can assist the first screw rod 13 and the second screw rod 14 to bear force, thereby improving the load-bearing capacity during lifting.

[0039] In one practicable manner, a limit assembly is also included, which includes two slides 19, and the two slides 19 are respectively fixed on the outer sides of the vertical ends of the two L-shaped clamping plates 7. A mounting block 20 is provided on the sliding element of the slide 19, and one end of the mounting block 20 is fixed on the sliding element of the slide 19. Slide rods 21 are symmetrically provided on the mounting block 20, and connecting blocks 22 are provided on the two slide rods 21. The connecting blocks 22 are slidably connected to the slide rods 21, and an L-shaped limit plate 24 is provided on one side of the connecting block 22 facing the middle of the slide rail 5. A second linear drive element 23 is provided on the connecting block 22, and the second linear drive element 23 is a hydraulic rod or a linear push rod. The second linear drive element 23 is fixed on the connecting block 22, and the output end of the second linear drive element 23 is set through the connecting block 22 and is fixed on the L-shaped limit plate 24.

[0040] The working principle of the above technical solution is:

[0041] When the hoisting segment 2 is hoisted to the specified assembly position, the height difference between the hoisted hoisting segment 2 and the end of the fixed cantilever segment 1 is difficult to align. Therefore, at this time, it is only necessary to slide the slide bar 21 to make the lateral end of the first L-shaped limit plate 24 be located below the end of the fixed cantilever segment 1, and then drive the L-shaped limit plate 24 to clamp the cantilever segment 1 through the second linear drive element 23 (so that the lateral end of the L-shaped limit plate 24 is located below the lower surface of the cantilever segment, and the vertical end is in close contact with the cantilever end), thereby eliminating the hoisting hoisting segment 2. The horizontal position difference between the end of the fixed cantilever segment 1 and the end of the fixed cantilever segment 1 is eliminated (located in the same plane at this time), and then the lifting equipment is controlled to lift upward. Due to the presence of the L-shaped limit plate 24, after lifting to a certain height, its lateral end is in close contact with the fixed cantilever segment 1, and it cannot be lifted further. At this time, the two segments are at the same height, and the height difference is eliminated. Then, the horizontal position difference and vertical height difference between the end of the hoisting segment 2 and the cantilever segment 1 can be quickly eliminated, so that the two can be quickly aligned to achieve rapid splicing;

[0042] The setting of the slide 19 can adjust the height of the L-shaped limit plate 24, and thus can adjust the vertical positions of two segments of different diameters. For example, when the hoisting segment 2 and the cantilever segment 1 are exactly the same, the L-shaped limit plate 24 and the L-shaped clamping plate 7 are at the same height. If the end diameter of the hoisting segment 2 is smaller than the cantilever segment 1, the slide 19 drives the L-shaped limit plate 24 to move downward and contact and limit the fixed part of the cantilever segment 1. At this time, the end of the hoisting segment 2 is located above the end of the fixed cantilever segment 1. Then, by adjusting the slide 19, the center of gravity alignment operation of segments with different end diameters can be realized.

[0043] In one practicable manner, two groups of clamping assemblies are included, a connecting truss 3 is provided between the two groups of clamping assemblies, and both ends of the connecting truss 3 are detachably connected to the U-shaped mounting frame 4 in the clamping assembly. The two groups of settings can clamp the two ends of the lifting segment 2 to improve the clamping stability. At the same time, it is not difficult to understand that the method of setting two groups of clamping assemblies and limit assemblies is more suitable as follows. Figure 1 In the segment hoisting environment shown, the two ends of the hoisting segment 2 need to be spliced ​​and installed with the ends of the cantilevered segment 1 on the outside of both ends. At this time, the limit assembly can better limit the upward movement of the ends of the hoisting segment 2. In this environment, the positioning speed of the hoisting segment 2 is faster and more accurate.

[0044] It should be noted that the rapid splicing hoisting device in the technical solution is used for hoisting segments, which can not only hoist building segments that meet the requirements, but also hoist and splice tower segments 26. Figure 8 and Fig. 9As shown, during hoisting, it is only necessary to clamp the L-shaped clamping plates 7 on both sides under the edge beam provided on one end of the tower segment 26, that is, the L-shaped clamping plates 7 are located under the edge beam, and the pressing block 10 is located above the middle beam, thus forming an extrusion clamp (if the clamping end of the tower segment 26 does not have a middle beam, it is only necessary to lengthen the length of the pressing block 10 so that it can contact and extrude with the edge beam), thereby ensuring the stability of the clamping, that is, after hoisting and splicing several tower segments 26, a tower body 27 is formed. The specific usage method can be adjusted according to actual conditions, and no further elaboration is made here.

[0045] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present invention.
