Description

Technical Field

[0001] The invention belongs to the technical field of composite slab construction, and in particular relates to a hoisting auxiliary device for composite slab construction. Background Art

[0002] As a common prefabricated component, composite slabs are increasingly used in building construction. The use of composite slabs can effectively improve construction efficiency, ensure project quality and reduce on-site wet work. However, there are many problems that need to be solved in the hoisting construction process of composite slabs.

[0003] At present, the installation of composite panels mainly relies on specific lifting equipment. In order to achieve the precise placement of the composite panels at the predetermined position of the building, 2 to 3 construction workers are usually required to work together to adjust the position of the composite panels by pulling them. However, the existing lifting equipment and winch rope of the composite panels are an integrated structure. When pulling the composite panels and their lifting equipment, the construction workers not only have to overcome the weight of the composite panels themselves, but also have to consume huge external force to offset the force applied by the winch rope. Especially in some complex construction scenarios, such as when the building structure design requires the composite panels to be rotated and replaced, the resistance faced by the construction workers is further increased, and the external force consumed increases exponentially. This high-intensity physical exertion not only reduces the construction efficiency and prolongs the construction period, but also increases the labor intensity of the construction workers, which can easily lead to fatigue work of the construction workers.

[0004] Therefore, a hoisting auxiliary device for composite slab construction is proposed. Summary of the invention

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] 1. Through the cooperation of the rotating mechanism, limiting mechanism, pulling mechanism, PLC controller and wireless remote control, construction workers do not need to spend huge external force to pull the composite plate and its hanger to adjust the position as in the traditional way. In addition, the rotation and horizontal position adjustment of the composite plate make the adjustment of the composite plate more labor-saving and convenient, greatly shortening the construction period, effectively avoiding fatigue caused by high-intensity physical exertion of construction workers, and reducing the risk of safety accidents. In addition, if only a single adjustment of the angle or horizontal position is required, the corresponding mechanism action can also be independently controlled to ensure the precise installation of the composite plate and the predetermined position of the building, thereby improving the construction quality.

[0025] 2. By coordinating the levelness monitoring mechanism with the variable resistance mechanism in the pulling mechanism, when one end of the composite board is lifted up when in contact with the predetermined position of the building, the circuit current can be changed according to the change in the tension of the installation rope by moving the conductive sleeve on the resistance rod, thereby controlling the magnetic force of the electromagnetic block to extend the levelness monitoring rod. Construction personnel can quickly judge the position and degree of the upward lift of the composite board based on the extended length of the levelness monitoring rod, and adjust the installation position of the composite board in time, further ensuring the accuracy and efficiency of the construction.

[0026] 3. By setting up the electric anti-drop pawl, after the construction personnel control the electric anti-drop pawl to close through the wireless remote control, it can ensure the firm connection between the hook and the composite plate, effectively preventing the composite plate from accidentally falling off during the lifting process, thereby improving the safety of the lifting operation. At the same time, it can be opened synchronously during disassembly, which is more convenient to operate. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0034] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0035] like Figure 1-Figure 6 As shown, a hoisting auxiliary device for composite slab construction includes a tower crane 1 and a mobile trolley 2 arranged on the tower crane 1, a winch 3 is fixedly provided at the bottom of the mobile trolley 2, and a lifting rope 4 is extended from the bottom of the winch 3, and also includes:

[0036] The balancing rope 5 is arranged at the lower end of the lifting rope 4. Four balancing ropes 5 are used. The lower ends of the four balancing ropes 5 are arranged at the four corners of the upper surface of the fixed hanging plate 6. The upper ends of the four balancing ropes 5 are fixedly connected to the lower end of the lifting rope 4. The design here can lift the fixed hanging plate 6 steadily. The fixed hanging plate 6 is fixedly arranged at the bottom of the balancing rope 5.

[0037] The movable hanging plate 7 is arranged below the fixed hanging plate 6. The lower surface of the fixed hanging plate 6 is provided with a sliding rod 8. The rod wall of the sliding rod 8 is provided with a sliding block 9. The bottom of the sliding block 9 is fixedly connected to the upper surface of the movable hanging plate 7. The sliding rod 8 adopts a square rod. The side wall of the sliding block 9 is provided with a square sliding hole matched with the rod wall of the sliding rod 8. Both ends of the sliding rod 8 are provided with connecting rods fixedly connected to both sides of the gear ring 101. The setting of the square structure can make the sliding block 9 slide smoothly on the sliding rod 8, and the connecting rod can ensure that the two ends of the sliding rod 8 can be fixedly connected upward;

[0038] The rotating mechanism 10 is arranged between the fixed hanger plate 6 and the sliding rod 8. The rotating mechanism 10 includes a ring gear 101. An annular groove is opened on the lower surface of the fixed hanger plate 6, and a support bearing 102 is fixedly arranged inside the annular groove. The ring gear 101 is rotatably arranged inside the annular groove through the support bearing 102. A first electric push rod 103 is fixedly arranged on one side of the ring gear 101, and a rack 104 is fixedly arranged on the moving end of the first electric push rod 103. The rack 104 is meshed with the ring gear 101. During the hoisting process, the construction personnel manually rotate the movable hanger plate 7 so that the movable hanger plate 7 together with the slider 9 and the sliding rod 8 on the upper surface can be rotated through the ring gear 101. When rotation is not required, the first electric push rod 103 is controlled to extend so that the rack 104 is meshed with the ring gear 101 to limit the circumferential position of the movable hanger plate 7.

[0039] The limiting mechanism 11 is arranged inside the slider 9. The limiting mechanism 11 includes a second electric push rod 111 fixedly arranged inside the slider 9. A limiting plate 112 is fixedly arranged on the moving end of the second electric push rod 111. Two limiting rods 113 are symmetrically fixedly arranged on the lower surface of the limiting plate 112. The rod wall of the slide bar 8 is provided with a limiting groove 114 that matches the two limiting rods 113. When it is necessary to adjust the horizontal position of the movable hanging plate 7, the construction personnel pull the movable hanging plate 7 to make the slider 9 move on the slide bar 8, and then In conjunction with the above-mentioned rotating mechanism 10, the movable hanger plate 7 can be adjusted in multiple directions on the horizontal position. When the horizontal position of the movable hanger plate 7 needs to be fixed, the second electric push rod 111 can drive the limit plate 112 to move when it retracts, so that the limit rod 113 moves out from the limit groove 114 on the slide bar 8, thereby releasing the position restriction between the slide bar 9 and the slide bar 8. On the contrary, when the second electric push rod 111 is extended, the position restriction between the slide bar 9 and the slide bar 8 can be restricted, thereby preventing the movable hanger plate 7 from sliding easily during the lifting process.

[0040] A lifting rope 12 is installed and arranged at the four corners of the lower surface of the movable hanging plate 7, and a hook 13 is fixedly provided at the lower end of the lifting rope 12, and an electric anti-slip pawl 14 is provided at the opening of the hook 13 (the electric anti-slip pawl 14 adopts a motor drive structure, and one end of the anti-slip pawl is fixedly connected to the output shaft of the motor, and the anti-slip pawl can be opened or closed by controlling the rotation of the motor). A pulling mechanism 15 is provided between the upper end of the lifting rope 12 and the movable hanging plate 7, and the pulling mechanism 15 includes a first shell 151 fixedly arranged on the lower surface of the movable hanging plate 7, and a pulling block 152 is vertically slidably provided inside the first shell 151, and the upper end of the lifting rope 12 extends to the interior of the first shell 151 and is fixedly connected to the bottom of the pulling block 152, and a first spring 153 is fixedly provided on the top of the pulling block 152, and the upper end of the first spring 153 is fixedly connected to the top inner wall of the first shell 151 A touch switch 154 is fixedly provided on the top inner wall of the first shell 151, and a variable resistance mechanism 20 is provided between the inner side of the first shell 151 and the pulling block 152. The variable resistance mechanism 20 includes a resistance rod 201 which is vertically fixed inside the first shell 151, and a conductive sleeve 202 is slidably provided on the rod wall of the resistance rod 201, and the conductive sleeve 202 is fixedly provided on the inner side of the pulling block 152. The pulling block 152 adopts an insulating block. During the lifting process of the composite plate, the lower ends of the four installation ropes 12 are subjected to force. At this time, the upper ends of the four installation ropes 12 pull down the pulling block 152, so that the pulling block 152 overcomes the elastic force of the first spring 153 and moves downward. At the same time, the conductive sleeve 202 also moves downward on the resistance rod 201. When the force on the lower ends of the installation ropes 12 is reduced, the elastic force of the first spring 153 pulls the installation rope 12 upward.

[0041] The level monitoring mechanism 16 is arranged at the four corners of the lower surface of the movable hanging plate 7. The level monitoring mechanism 16 includes a second shell 161 fixedly arranged on the lower surface of the movable hanging plate 7. A moving block 162 is vertically slidably arranged inside the second shell 161. A second spring 163 is fixedly arranged at the bottom of the moving block 162, and the lower end of the second spring 163 is fixedly connected to the bottom of the second shell 161. A level monitoring rod 164 extending to the outside of the second shell 161 is fixedly arranged at the bottom of the moving block 162. A permanent magnet block 16 is fixedly arranged on the top of the moving block 162. 5. The bottom of the second shell 161 is fixedly provided with an electromagnetic block 166, and the resistance rod 201 and the conductive sleeve 202 are electrically connected to the electromagnetic block 166. After the electromagnetic block 166 is powered on, the repulsive magnetic force generated by itself can push the permanent magnet block 165 downward to move, and at the same time, the moving block 162 overcomes the elastic force of the second spring 163 and moves downward and pushes out the level monitoring rod 164. When the electromagnetic block 166 is powered off or the current is reduced, the moving block 162 and the level monitoring rod 164 move upward under the elastic force of the second spring 163.

[0042] The wireless communication module 17 is arranged on the lower surface of the movable hanger 7; the PLC controller 18 is arranged on the lower surface of the movable hanger 7, and the rotating mechanism 10, the limiting mechanism 11, the pulling mechanism 15, the electric anti-slip pawl 14, the levelness monitoring mechanism 16 and the wireless communication module 17 are all electrically connected to the PLC controller 18; the wireless remote control 19 is connected to the PLC controller 18 signal through the wireless communication module 17.

[0043] The operating principle of the present invention is described as follows: the construction personnel first operate the mobile trolley 2 to move on the tower crane 1, and then control the winch 3 to release the lifting rope 4, so that the fixed hanging plate 6, the movable hanging plate 7 and the hook 13 are moved to the composite plate placement area (the construction personnel operate inside the chassis of the tower crane 1 during this process), and then the construction personnel hold the wireless remote control 19 to control the electric anti-detachment pawls 14 on the four hooks to open, and then hang the four hooks 13 correspondingly at the four corners of the surface of the composite plate (the surface of the composite plate is prefabricated with raised steel bar hanging rings for hook hanging areas), and then hold the wireless remote control 19 The electric anti-slip pawl 14 is closed, and the wireless remote controller 19 is connected to the PLC controller 18 by wireless signals through the wireless communication module 17. The wireless communication module 17 can adopt a Bluetooth module, and the PLC controller 18 is provided with a Bluetooth signal receiving module. After being operated, the wireless remote controller 19 can feedback an electrical signal to the PLC controller 18, and the PLC controller 18 controls the action of the electric anti-slip pawl 14 to ensure a stable connection between the hook and the composite plate. After the composite plate is hung, the construction personnel operate the tower crane 1, the mobile trolley 2 and the winch 3 to lift the composite plate and transport it to the predetermined position of the building;

[0044] When the composite plate is lifted by the four hooks 13, the lower ends of the four installation ropes 12 are subjected to force. At this time, the upper ends of the four installation ropes 12 pull down the pulling block 152, so that the pulling block 152 overcomes the elastic force of the first spring 153 and moves downward.

[0045] When the composite board is hoisted to a position close to the predetermined position of the building and the position of the composite board needs to be adjusted significantly, the construction personnel send an electrical signal to the PLC controller 18 by operating the wireless remote controller 19 (there are at least two wireless remote controllers 19, one wireless remote controller 19 is on the construction personnel at the position where the composite board is placed, and the other wireless remote controller 19 is on the construction personnel at the predetermined position of the building), so that the PLC controller 18 controls the first electric push rod 103 to retract and the second electric push rod 111 to retract, and the first electric push rod 103 can drive the rack 104 and the ring gear 101 is separated, and the position restriction of the gear ring 101 is released. The construction worker pulls the movable hanging plate 7 by hand, so that the movable hanging plate 7 together with the slider 9 and the slide bar 8 on the upper surface are rotated by the gear ring 101, and the gear ring 101 can rotate on the lower surface of the fixed hanging plate 6 through the support bearing 102, so that the movable hanging plate 7 and the overlapping plate below can be rotated and adjusted. The second electric push rod 111 can drive the limit plate 112 to move, so that the limit rod 113 moves out of the limit groove 114 on the slide bar 8, and the position between the slider 9 and the slide bar 8 is released. The construction worker then pulls the movable hanging plate 7 by hand, so that the slider 9 on the upper surface of the movable hanging plate 7 slides on the slide rod 8, so that the horizontal position of the movable hanging plate 7 and the underlying composite plate can be adjusted. The combination of horizontal position adjustment and angle rotation adjustment can adjust the composite plate in multiple directions, so that the composite plate can be accurately installed between the predetermined position of the building. Since the rotation angle adjustment and horizontal position adjustment assist the construction workers in manually adjusting the position of the composite plate, it is more labor-saving than several construction workers pulling the composite plate synchronously to adjust and install it. After the position is adjusted appropriately, the construction personnel operate the wireless remote controller 19 to control the first electric push rod 103 to extend and the second electric push rod 111 to extend, and the position of the gear ring 101 and the slider 9 is restricted and fixed until the positioning installation is completed. In addition, if the composite plate only needs to be adjusted in angle or horizontal position, the PLC controller 18 can independently control the first electric push rod 103 and the second electric push rod 111. The whole process does not require multiple construction personnel to pull the lifting rope 4 vigorously to adjust the position of the composite plate, making the adjustment of the composite plate more labor-saving, thereby improving the construction efficiency;

[0046] When the position of the composite board is adjusted, the winch 3 slowly controls the lowering of the lifting rope 4, and the composite board also slowly descends. This process is sufficient to ensure the position adjustment of the composite board. After the position adjustment of the composite board is completed, the construction workers can hold the fixed hanging board 6 by hand until the composite board slowly falls to the predetermined position of the building. If one end of the composite board is tilted during the contact with the predetermined position of the building, the upward tilted part of the composite board reduces the tension on the installation rope 12, and the tension on the installation rope 12 of the non-tilted part increases (from the perspective of force balance, the non-tilted part has to bear more weight of the composite board than before to maintain the overall balance, so the tension on the installation rope 12 of this part will increase, and the tilted part has a tendency to tilt upward, which is equivalent to that part of its weight is no longer completely borne by the installation rope 12 at the corresponding position, so the tilted part has a greater impact on the installation rope The tension of the rope 12 will decrease), so that the upper end of the installation rope 12 with reduced tension moves upward under the elastic force of the first spring 153, and the pulling block 152 also moves upward. The pulling block 152 drives the conductive sleeve 202 to move on the conductive rod during the upward movement. At this time, the resistance of the conductive rod itself decreases, so that the current connected to the conductive rod and the electromagnetic block 166 in the same circuit increases. When the current increases, the repulsive magnetic force generated by the electromagnetic block 166 itself also increases, thereby pushing the permanent magnet block 165 downward to move, and at the same time, the moving block 162 overcomes the elastic force of the second spring 163 and moves downward to push out the level monitoring rod 164, so that the construction personnel can observe the extended length of the level monitoring rod 164 to determine the upward tilting position and tilting degree of the composite plate here, which can ensure that the construction personnel can quickly adjust the installation position of the composite plate, thereby improving the construction efficiency;

[0047] After the construction workers have made multiple adjustments and installed the composite board accurately and horizontally, the extended lengths of the horizontality monitoring rods 164 at the four corners of the lower surface of the movable hanging plate 7 are all short and consistent. At this time, the construction workers operate the wireless remote control 19 to send an electrical signal to the PLC controller 18, so that the PLC controller 18 synchronously opens the electric anti-detachment ratchets 14 on the four hooks 13, and then the construction workers directly remove the four hooks 13 from the composite board.

[0048] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
