Description

Technical Field

[0001] The utility model relates to the field of building construction, in particular to a hoisting structure for modular integrated building concrete modules. Background Technique

[0002] During the building construction process, construction workers may use modular integrated building concrete modules for building construction. The modular integrated building concrete modules are generally pre-produced by customization in a factory and then transported to the construction site for rapid erection. During the on-site construction process, the modular integrated building concrete modules need to be hoisted.

[0003] The hoisting of the prior art is generally carried out by a crane. A hoisting fixture is installed on the hook of the crane. After the hoisting fixture receives an upward pulling force from the crane, the lower end of the fixture clamps inward, thereby clamping the building concrete module. However, the sizes and dimensions of the concrete modules are different. If the size of the fixture is larger than the concrete module, it is easy to cause that the concrete module cannot be clamped after the lower end of the fixture tightens. If the size of the fixture is smaller than the concrete module, the concrete module cannot be clamped at the clamping position of the fixture. The hoisting structure in the prior art is difficult to adjust the size, resulting in its inability to adapt to the size of the concrete module. Content of the Utility Model

[0038] Embodiment 1: The purpose of this embodiment is to propose a modular integrated building concrete module hoisting structure.

[0039] According to Figures 1 to 4 , it includes a vertical telescopic rod 1;

[0040] The vertical telescopic rod 1 extends in the up and down direction. The vertical telescopic rod 1 includes a guide frame 101 which extends vertically. A chute extending in the up and down direction is formed on the guide frame 101. The chute has an open upper end and a closed lower end structure, and a support rod 102 is slidably arranged in the chute.

[0041] A fixed block 103 is fixedly connected to the bottom wall of the guide frame 101. There is a gap between the fixed block 103 and the support rod 102. A locking rod 104 extending in the up and down direction is hinged on the fixed block 103. A locking groove 105 is formed in the lower part of the support rod 102. The upper end of the locking rod 104 is fixedly connected with a limiting rod extending in the front and back directions, and the limiting rod is slidably arranged inside the locking groove 105.

[0042] The locking groove 105 includes a vertical chute and a locking block. The vertical chute is formed in the lower part of the front side of the support rod 102. A vertically extending locking block is fixedly connected in the vertical chute. The gap between the inner wall of the vertical chute and the outer side of the locking block forms a loop-shaped chute, and the limiting rod can slide in the loop-shaped chute.

[0043] The top wall of the vertical chute extends downward to form a V-shaped protrusion. The top of the locking block is provided with a V-shaped notch. The position of the V-shaped notch corresponds to the position of the V-shaped protrusion up and down. The gap between the position of the V-shaped notch and the V-shaped protrusion forms a V-shaped chute. When the limiting rod is at the lowest position in the V-shaped chute, the locking rod 104 locks the support rod 102.

[0044] The lower end of the guide frame 101 is fixedly connected with a mounting frame 106, and the mounting frame 106 is connected to the mounting cross beam 5 through mounting bolts.

[0045] A clamping mechanism 6 is arranged on the mounting cross beam 5. The clamping mechanism 6 includes two brackets 601 extending in the front and back directions. A chute that is transparent from left to right is formed in the bracket 601. The bracket 601 is movably sleeved on the mounting cross beam 5 through the chute. A locking member is arranged on the bracket 601. The locking member includes a locking hole 501. A plurality of locking holes 501 arranged in the left and right directions are formed on the upper surface of the mounting cross beam 5. A locking socket is formed on the bracket 601. A locking bolt 502 is inserted between the locking socket and the corresponding locking hole 501, and a nut is threadedly connected to the locking bolt 502.

[0046] Left clamping frames 602 are hinged on the front and back sides of the left bracket 601.

[0047] Padding plates 605 are fixedly connected to the front and back sides of the right bracket 601. The thickness of the padding plate 605 is equal to the thickness of the left clamping frame 602. Right clamping frames 606 are hinged on the padding plates 605. The right clamping frames 606 and the left clamping frames 602 are corresponding to each other left and right. The left clamping frames 602 and the right clamping frames 606 both extend vertically. The upper ends of the left clamping frames 602 and the right clamping frames 606 are fixedly connected with inclined connecting support plates.

[0048] The upper parts of the connecting support plates corresponding to each other left and right are staggered and crossed front and back to form an X structure, and the crossing points of the two connecting support plates correspond to the position of the vertical telescopic rod 1 front and back. A support column 604 extending in the front-back direction is fixedly connected between the upper ends of the connecting support plates corresponding to each other front and back. The support column 604 is located below the rope connecting frame 4 on the same side. The ropes extending from the rope connecting frame 4 bypass below the support column 604 and then extend upward and are fixedly connected to the rope winding drum 301 on the same side.

[0049] A connecting beam 603 extending in the front-back direction is fixedly connected between the lower ends of the two left clamping frames 602 and between the lower ends of the two right clamping frames 606. Friction pads 7 are fixedly connected to the opposite surfaces of the two connecting beams 603. The friction pads 7 can be made of rubber material.

[0050] The upper end of the support rod 102 is fixedly connected to a support cross beam 2. A connecting frame 3 is fixedly connected to the upper surface of the support cross beam 2. A hook connecting frame 8 adapted to the hook is provided on the connecting frame 3.

[0051] Rope connecting frames 4 are fixedly connected to the upper parts of the left and right side surfaces of the guide frame 101. The positions of the two rope connecting frames 4 correspond to each other left and right, and ropes are fixedly connected to the opposite ends of the two rope connecting frames 4. Installation avoidance grooves are formed on the left and right sides of the connecting frame 3. Rotatable lockable rope winding drums 301 are provided in the installation avoidance grooves. The ends of the ropes far from the rope connecting frames 4 are fixedly connected to the rope winding drums 301. The rope winding drums 301 are used to adjust the tension of the ropes. The rotation of the rope winding drums 301 can be locked by using a pin-type locking method for the rope winding drums 301.

[0052] Avoidance grooves 201 that are vertically penetrating are formed on the left and right side surfaces of the support cross beam 2. A support column extending in the front-back direction is fixedly connected in the avoidance grooves 201. The outer surface of the support column contacts the rope.

[0053] Working principle: Before construction, first connect the hook connecting frame 8 with the hook of the crane for installation. Then, apply a downward pressure to the support rod 102. When the support rod 102 is stressed, the V-shaped chute contacts the limit rod. The V-shaped protrusion on the vertical chute guides the limit rod to slide left and right downward to both sides, thereby driving the locking rod 104 to swing left and right until the limit rod slides out of the V-shaped chute, so that the support rod 102 is unlocked. Then, apply an upward pulling force to the hook connecting frame 8 through the crane, thereby driving the connecting frame 3 upward. The upward movement of the connecting frame 3 drives the support rod 102 upward. The upward movement of the support rod 102 causes the limit rod to continue to slide downward in the locking groove 105. During this process, the upward movement of the support rod 102 drives the support crossbeam 2 upward, thereby tightening the rope. The tightened rope drives the support column 604 upward, so that both the right clamping frame 606 and the left clamping frame 602 swing in opposite directions with the connection point with the bracket 601 as the center, thereby reducing the distance between the two connecting beams 603, and thus clamping the concrete module.

[0054] After the concrete module is clamped, the right clamping frame 606 and the left clamping frame 602 stop swinging, so that the movement of the support column 604 is limited, and the rope applies a pulling force to the support crossbeam 2, so that the movement of the support rod 102 stops.

[0055] When the crane hoists the concrete module to the designated position, the hook of the crane moves downward, so that the support rod 102 resets, so that the limit rod slides back into the V-shaped chute, and the limit rod falls back to the V-shaped notch, so that the limit rod is locked again. The reset of the support rod 102 causes the distance between the connecting beams 603 to reset, and the concrete module disengages from the contact with the connecting beams 603. The crane hoists the lifting structure again. During the hoisting process, since the limit rod is locked, the movement of the support rod 102 is also locked, and the concrete module is lowered.

[0056] When adjusting the size, remove the locking bolt 502 to release the lock of the bracket 601 on the installation crossbeam 5, and at the same time release the lock of the rope winding drum 301. Then move the bracket 601 to adjust the gap between the two connecting beams 603. When the gap reaches the appropriate distance, reinsert the locking bolt 502 between the locking socket and the corresponding locking hole 501, and then screw on the nut to lock it.

[0057] When expanding the distance between the connecting beams 603, during the movement of the bracket 601, the rope winding drum 301 rotates, and the length of the rope is extended.

[0058] When reducing the distance between the connecting beams 603, after the bracket 601 completes the movement, rotate the rope winding drum 301 to shorten the length of the rope.

[0059] After the adjustment is completed, lock the rope winding drum 301 again.

[0060] Thus, the hoisting structure can be conveniently installed on the crane. At the same time, the clamping of the hoisting structure and the lowering of the concrete module are relatively convenient. Moreover, the distance between the connecting beams 603 can be adjusted by moving the support 601 and tightening the ropes, so that the hoisting structure can be adapted to concrete modules of different sizes.

[0061] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments, and the present utility model can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be embraced within the present utility model. Any reference signs in the claims should not be construed as limiting the claims involved.
