Description

Technical Field

[0001] The invention relates to the technical field of building construction, and in particular to a hoisting mechanism for building construction. Background Art

[0002] As is known, when installing a prefabricated wall, the prefabricated wall is first lifted by a crane, and then installed in a corresponding ground foundation groove. Specifically, when installing, the hook is first hooked on the load ring reserved on the prefabricated wall, and then it is lifted. When it falls to 60-80 cm from the base, it stops falling. The staff manually supports and straightens the suspended prefabricated wall so that it corresponds to the foundation groove, and then slowly falls and finally puts it into the foundation groove;

[0003] For example, the Chinese patent with application number "202110146802.3" and patent name "A hoisting mechanism for construction" includes a frame, a telescopic arm and a hook assembly. The upper part of the frame is rotatably connected to one end of the telescopic arm, and the lower part of the frame is provided with rollers, and the lower part of the frame is also provided with a fixing assembly; when it is necessary to hoist the object during actual construction and use, the entire device can be moved to the required position through the rollers, and then the hoisting direction can be adjusted through the rollers, and the fixing assembly is operated and fixed through the fixing assembly, and then the hook assembly is connected to the hoisted object, and the winding mechanism is operated to lift the hoisted object by the hook assembly. When the hoisting position needs to be adjusted, the hook assembly can be moved on the slide slot and fixed through the card slot, thereby better adjusting the hoisting direction, and the hoisting mechanism can be conveniently fixed, thereby improving the stability of the hoisting mechanism, and the hoisting position can be adjusted after the hoisting mechanism is fixed.

[0004] The shortcomings of the prior art are that in the prior art, such as the above-mentioned patent, when installing, it is necessary to stop when it falls 60-80 cm from the base, and then the staff needs to manually support and straighten the suspended prefabricated wall before it can slowly fall. This hoisting mechanism not only consumes time during the hoisting process, but also requires the staff to manually support it, which has certain safety hazards. Summary of the invention

[0005] The purpose of the present invention is to provide a hoisting mechanism for construction to solve the above-mentioned deficiencies in the prior art.

[0006] In order to achieve the above object, the present invention provides the following technical solutions:

[0007] A lifting mechanism for construction includes a lifting rod and two hooks arranged below the lifting rod, and also includes a load-bearing assembly, wherein the load-bearing assembly is used to support the lower corners of a wall, the load-bearing assembly includes a connecting block and a telescopic column slidably arranged on the connecting block, and a limiting assembly is also arranged on the telescopic column. When the lifting device moves downward, the limiting assembly is driven to be pulled out laterally and abut against the two side walls of a base groove on the ground to limit the lateral position of the load-bearing assembly, thereby limiting the hoisted wall. Specifically, the hook is connected to the connecting block by a pull rope, and through the provided load-bearing assembly and the limit assembly, when the lifting device moves downward, the limit assembly can be driven to be pulled out horizontally, and the pulled-out position can abut against the two side walls of the base groove on the ground, so that the load-bearing assembly can be limited, and the hoisted wall can be limited, and then the hoisted wall can be limited, so that the hoisted wall can automatically correspond to the notch of the base groove, that is, there is no need for manual support, which reduces safety hazards, and there is no need to stop during the hoisting process, thereby greatly improving the hoisting efficiency of the device.

[0008] As a further preferred solution of this embodiment, the limit assembly is arranged below the telescopic column, and the limit assembly includes an extension rod fixedly arranged on the telescopic column, and a limit rod slidably arranged on the extension rod, and the limit rod can slide out along the direction of the extension rod to abut against the side wall of the base groove. When abutting, the limit rod can be restricted and its position can be limited.

[0009] As a further preferred solution in this embodiment, the limit assembly further includes a telescopic rod slidably arranged on the telescopic column, and two hinged rods are slidably hinged below the telescopic rod, and the other ends of the two hinged rods are respectively rotatably arranged on the limit rod;

[0010] When the wall moves downward, the telescopic rod gradually squeezes the ground and expands and contracts relatively with the telescopic column, thereby driving the two hinged rods to move and driving the two limit rods to slide out along the extension rod to contact the side wall of the base.

[0011] As a further preferred solution in this embodiment, a locking assembly for locking the connecting block is provided at the upper end of the telescopic column, and the locking assembly includes two locking blocks that slide laterally and a first elastic member arranged between the two locking blocks. Under the elastic force of the first elastic member, the two locking blocks can be inserted into the grooves provided on the connecting block to limit the relative sliding between the connecting block and the telescopic column.

[0012] As a further preferred solution in this embodiment, a limit column is provided at the upper end of the telescopic rod, and an oblique groove adapted to the limit column is provided on the locking block, and the limit column can be inserted into the oblique groove, and when the limit column moves upward, the limit column is driven to be inserted into the oblique groove, so as to drive the two locking blocks to disengage from the grooves provided on the connecting block, so that the connecting block and the telescopic column slide relative to each other.

[0013] As a further preferred scheme in this embodiment, the bearing mechanism includes a bearing rod rotatably arranged on a connecting block, and a plug-in rod which can be inserted into the rotating shaft of the bearing rod is also slidably arranged on the connecting block to limit the rotation of the bearing rod, and a rotating block is rotatably arranged at one end of the plug-in rod, and a torque spring is arranged on the axis on which the rotating block and the plug-in rod rotate, and its elastic force can make the rotating block and the plug-in rod in a straight line state; in this embodiment, the prefabricated wall can be supported by the setting of the bearing mechanism, so that it can support the prefabricated wall through the setting of the bearing mechanism, that is, in this embodiment, the prefabricated wall is synchronously supported by the setting of the hook and the bearing mechanism, which greatly improves the stability of the prefabricated wall during hoisting, and the setting of the bearing mechanism prevents the hook from loosening or falling, thereby greatly reducing safety hazards.

[0014] When the telescopic column slides upward relative to the connecting block, it can drive the rotating block to move upward, that is, drive the connected plug rod to move upward synchronously, so that the plug rod is separated from the bearing rod, so that the bearing rod can rotate.

[0015] As a further preferred scheme in this embodiment, a driving gear is arranged on the shaft of the bearing rod, and a transmission rack meshing with the driving gear is slidably arranged on the connecting block. After the plug-in rod moves up for a certain period of time, the transmission rack can be driven to move up to drive the driving gear to rotate, so that the bearing rod rotates and releases the load on the wall.

[0016] As a further preferred solution in this embodiment, a third elastic member is provided in the connecting block, and when the telescopic rod drives the hinge rod to move, the third elastic member does not undergo elastic deformation.

[0017] As a further preferred solution in this embodiment, it includes a fixed block fixedly set on the lifting rod, and one end of the hook is inserted into the fixed block, and a bearing block is rotatably arranged, and a friction plate is also arranged in the fixed block, which presses on the friction plate to limit the rotation of the hook after the hook is pressed.

[0018] As a further preferred scheme in this embodiment, a bearing is arranged on the outer wall of the hook, and a second elastic member is arranged on the outer wall of the hook. When the hook is not under pressure, the load-bearing block is separated from the friction plate under the elastic force of the second elastic member so that the hook can rotate. This allows the hook to rotate freely when the hook is not hoisting heavy objects, i.e., it greatly facilitates the use of the hook. The hook can be rotated according to the direction of the ring mouth of the prefabricated wall lifting ring, which greatly improves its convenience. When the hook is bearing weight, the rotation of the hook can be restricted under the action of the load-bearing block and the friction plate, which greatly improves the stability of the hook during hoisting.

[0019] In the above technical solution, the hoisting mechanism for construction provided by the present invention has the following beneficial effects:

[0020] The present invention provides a load-bearing component and a limiting component, which can drive the limiting component to be pulled out horizontally when the hoisting device moves downward, and the pulled-out position can abut against the two side walls of the base groove on the ground, so that the load-bearing component can be limited, and the hoisted wall can be limited, and then the hoisted wall can be limited, so that the hoisted wall can automatically correspond to the notch of the base groove, that is, there is no need for manual support, which reduces safety hazards, and there is no need to stop during the hoisting process, thereby greatly improving the hoisting efficiency of the device.

When the collision occurs, the limit rod 231 can be restricted and its position can be limited. The limit assembly also includes a telescopic rod 211 slidably arranged on the telescopic column 21, and two hinged rods 212 are slidably hinged below the telescopic rod 211, and the other ends of the two hinged rods 212 are respectively rotatably arranged on the limit rod 231;

[0041] When the wall moves downward, the telescopic rod 211 gradually squeezes the ground 11 and the telescopic column 21 is relatively telescoped, so as to drive the two hinge rods 212 to move and drive the two limit rods 231 to slide out along the extension rod 23 to resist the side wall of the base.

[0042] In an embodiment further provided by the present invention, a locking assembly for locking the connecting block 2 is provided at the upper end of the telescopic column 21, and the locking assembly includes two locking blocks 24 that slide laterally and a first elastic member 241 provided between the two locking blocks 24. Under the elastic force of the first elastic member 241, the two locking blocks 24 can be inserted into the grooves provided on the connecting block 2 to limit the relative sliding between the connecting block 2 and the telescopic column 21.

[0043] In an embodiment further provided by the present invention, a limiting column is provided at the upper end of the telescopic rod 211, and an inclined groove 2401 adapted to the limiting column is provided on the locking block 24, and the limiting column can be inserted into the inclined groove 2401, and when the limiting column moves upward, the limiting column is driven to be inserted into the inclined groove 2401, so as to drive the two locking blocks 24 to disengage from the grooves provided on the connecting block 2, so that the connecting block 2 and the telescopic column 21 slide relative to each other.

[0044] In an embodiment further provided by the present invention, the bearing mechanism includes a bearing rod 22 rotatably arranged on the connecting block 2, and a plug-in rod 25 which can be inserted into the rotating shaft of the bearing rod 22 is also slidably arranged on the connecting block 2 to limit the rotation of the bearing rod 22, and a rotating block 251 is rotatably arranged at one end of the plug-in rod 25, and a torque spring is arranged on the axis on which the rotating block 251 rotates with the plug-in rod 25, and its elastic force can make the rotating block 251 and the plug-in rod 25 in a straight line state; in this embodiment, the prefabricated wall 1 can be supported by the setting of the bearing mechanism, so that it can support the prefabricated wall 1 through the setting of the bearing mechanism, that is, in this embodiment, the prefabricated wall 1 is synchronously supported by the setting of the hook 31 and the bearing mechanism, which greatly improves the stability of the prefabricated wall 1 during hoisting, and the setting of the bearing mechanism prevents the hook 31 from loosening or falling, thereby greatly reducing safety hazards.

[0045] When the telescopic column 21 slides upward relative to the connecting block 2, it can drive the rotating block 251 to move upward, that is, drive the connected plug rod 25 to move upward synchronously, so that the plug rod 25 is separated from the bearing rod 22, so that the bearing rod 22 can rotate.

[0046] In an embodiment further provided by the present invention, a driving gear 221 is provided on the axis of the load-bearing rod 22, and a transmission rack 252 meshing with the driving gear 221 is slidably provided on the connecting block 2. After the plug-in rod 25 moves up for a period of time, the transmission rack 252 can be driven to move up, thereby driving the driving gear 221 to rotate, so that the load-bearing rod 22 rotates and releases the load on the wall.

[0047] Furthermore, a third elastic member is provided in the connecting block 2 , and when the telescopic rod 211 drives the hinge rod 212 to move, the third elastic member does not undergo elastic deformation.

[0048] In the embodiment further provided by the present invention, it also includes a fixed block 315 fixedly set on the lifting rod 3, and one end of the hook 31 is inserted into the fixed block 315, and a bearing block 314 is rotatably set, and a friction plate 316 is also set in the fixed block 315. After the hook 31 is compressed, it presses on the friction plate 316 to limit the rotation of the hook 31. A bearing 312 is set on the outer wall of the hook, and a second elastic member 313 is set on the outer wall of the hook 31. When the hook 31 is not compressed, under the elastic force of the second elastic member 313, the bearing block 314 is separated from the friction plate 316, so that the hook 31 can rotate. In this embodiment, the fixed block 315, the second elastic member 313 and other structures are arranged, so that the hook 31 can be rotated at will when the hook 31 is not hoisting a heavy object, that is, it is greatly convenient to use the hook 31, and the hook 31 can be rotated according to the direction of the ring mouth of the prefabricated wall 1, which greatly improves its convenience, and when the hook 31 is bearing a load, the rotation of the hook 31 can be restricted under the action of the bearing block 314 and the friction plate 316, that is, the stability of the hook 31 during hoisting is greatly improved.

[0049] When the present invention is used, the hook 31 is firstly hoisted on the hoisting ring provided on the prefabricated wall 1, and then the bearing rod 22 provided under the connecting block 2 is pressed against the bottom of the prefabricated wall 1 to support the prefabricated wall 1, and then the prefabricated box is hoisted by the crane, so that the prefabricated wall 1 gradually falls into the foundation opened under the ground 11, and then when moving down, no manual support is required. Specifically, when moving down, the telescopic lowermost end under the telescopic column 21 is gradually pressed down and contacts the lowest surface of the foundation. After that, when the pressure is continuously pressed down, the telescopic rod 211 is gradually pushed to expand and contract along the telescopic column 21. The hinge rod 212 rotatably mounted on the telescopic column 21 is opened, and at the same time, the hinge rod 212 rotatably mounted on the telescopic column 21 is also rotated, that is, when rotating, the other end drives the connected limit rod 231 to slide out along the direction of the extension rod 23. During the sliding out process, the limit rod 231 gradually contacts the two side walls of the foundation pit. Since the two slide out synchronously, the position of the telescopic column 21 is gradually calibrated during the sliding out process, and finally the position of the prefabricated wall 1 supported on the support rod 22 is gradually corrected, which has a limiting function for the prefabricated wall 1. Then, during the continuous upward movement of the telescopic rod 211, the top of the telescopic rod 211 is The connected protruding column 2111 is gradually inserted into the oblique groove 2401 provided on the locking block 24, and then gradually squeezes the oblique groove 2401 during the gradual movement, so that the connected locking block 24 contracts inward, that is, the locking block 24 is separated from the connecting block 2, and then, when the upward movement continues, the telescopic column 21 is driven to move upward, that is, the telescopic rod 211 drives the telescopic column 21 to move upward synchronously when moving upward, and then, in the process of moving upward, it gradually contacts the rotating block 251, and then the rotating block 251 drives the connected plug rod 25 to move upward synchronously, and then the plug can be driven. The rod 25 disengages from the groove on the driving gear 221, and then when moving upward, it drives the connected transmission rack 252 to move upward, that is, it can drive the driving gear 221 meshing on the transmission rack 252 to rotate, that is, it drives the load-bearing rod 22 connected to the driving gear 221 to rotate downward, so that the load-bearing rod 22 no longer bears the prefabricated wall 1, and at this time the position of the prefabricated box is also determined, so that the limiting rods 231 on both sides are perpendicular to the side walls of the foundation pit, so that the prefabricated wall 1 can be limited to be parallel to the side walls of the foundation pit, and then it can be automatically straightened without manual support, thereby greatly improving the lifting efficiency.

[0050] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
