Description

Technical Field

[0001] The present invention relates to the technical field of laminated slab lifting tools, and specifically relates to a lifting tool for laminated slab construction. Background Technique

[0002] The precast laminated slab is an assembled monolithic floor slab formed by laminating a precast layer and a cast-in-place reinforced concrete layer. It has the advantages of the integrity of the cast-in-place floor slab, large stiffness, good crack resistance, no increase in steel consumption, and saving of formwork, and is widely used in prefabricated buildings.

[0003] When the current laminated slab is under construction and installation, usually the tower crane lifts the laminated slab to the corresponding position, and the workers push the laminated slab to directly above the position where it needs to be installed, and then communicate with the tower crane driver through a walkie-talkie to transmit the information that the laminated slab needs to be lowered to the tower crane driver, and the tower crane driver then controls the laminated slab to descend. If the position of the laminated slab needs to be moved after descending, it is also necessary to notify the tower crane driver to lift the position of the laminated slab, and then adjust the position of the laminated slab and then lower it, which consumes a lot of time. Moreover, when lifting the laminated slab, the traditional laminated slab lifting tool can only lift one piece at a time, and the lifting process is slow, reducing the installation efficiency of the laminated slab. At present, during the installation process of the laminated slab, people manually pull the laminated slab suspended in the air to control the position between the laminated slab and the wall during the installation process. During this process, there are disadvantages such as low installation efficiency, high danger coefficient, and poor accuracy of the laminated slab.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] 1. Through the arrangement of the supporting mechanism and the transportation mechanism, the transportation mechanism transports a number of laminated plates to be installed onto a number of wedge-shaped blocks. The mounting frame is hoisted above the wall where the laminated plates need to be installed by an external driving device, and then the laminated plates are installed.

Specific embodiments

[0030] Please refer to Figure 1-10 , the present invention provides a technical solution: a hoist for laminated plate construction, including a mounting frame 1, the bottom of the mounting frame 1 is slidably connected with a bearing plate 2; a first spring 3 for its reset is fixedly connected to the bearing plate 2, a pusher mechanism is arranged on the bearing plate 2, a positioning mechanism is arranged at the bottom of the bearing plate 2, and support mechanisms are arranged on both the left and right sides of the mounting frame 1; a feeding mechanism is arranged below the support mechanism, and the feeding mechanism is used to send the laminated plate 4 placed on the support mechanism to the bearing plate 2 again after the pusher mechanism pushes the laminated plate 4 placed on the bearing plate 2 out of the bearing plate 2; a transportation mechanism is arranged at the top of the mounting frame 1, and the transportation mechanism is used to transport the laminated plate 4 to the support mechanism.

[0031] When the present invention is in use, first place the mounting frame 1 at a designated position, start the transport mechanism, and move the laminated board 4 placed on the ground onto the support mechanism. The setting of the support mechanism enables the external driving device to lift several laminated boards 4 each time. The external driving device simultaneously lifts more laminated boards 4 to the position where the laminated boards 4 need to be installed, thereby improving work efficiency. Start the external driving device to lift the mounting frame 1 and several laminated boards 4 placed on the support mechanism above the wall where the laminated boards 4 need to be installed. The external driving device moves downward, and the mounting frame 1 moves downward under the action of gravity, so that the wall where the laminated boards 4 need to be installed is within the positioning range of the positioning mechanism. The external driving device enables the mounting frame 1 to continue moving downward. The bottom of the bearing plate 2 slidably connected to the bottom of the mounting frame 1 contacts the top of the wall, and the position of the bearing plate 2 remains unchanged under the action of the wall. The mounting frame 1 moves downward to drive the positioning mechanism to position and clamp the side of the wall where the laminated board needs to be installed. The positioning mechanism ensures that the bearing plate 2 is located in the middle position between the two walls, and further ensures that the laminated board 4 is located in the middle position of the wall where the laminated board 4 needs to be installed, so that the position difference between the laminated board 4 and the wall is controlled within the allowable range, improving the installation accuracy of the laminated board 4. After the bearing plate 2 is located in the middle position of the wall, start the pushing mechanism. The pushing mechanism moves forward to drive the support mechanism to rotate. The rotation of the support mechanism causes the laminated board 4 to fall onto the feeding mechanism. When the pushing mechanism moves to the limit position, the laminated board 4 falls onto the feeding mechanism. At the same time, the pushing mechanism triggers the feeding mechanism, enabling the pushing mechanism to transmit power to the feeding mechanism. The pushing mechanism moves in the reverse direction to return to the initial position. During this process, the pushing mechanism does not drive the support mechanism to rotate in the reverse direction. During the process of the pushing mechanism returning to the initial position, the pushing mechanism drives the feeding mechanism to send the laminated board 4 onto the bearing plate 2. At the same time, when the pushing mechanism returns to the initial position, the pushing mechanism triggers the feeding mechanism again, so that there is no longer power transmission between the pushing mechanism and the feeding mechanism. The pushing mechanism works again, pushing the laminated board 4 staying on the bearing plate 2 out of the bearing plate 2 and installing it on the top of the wall. After the installation is completed, the pushing mechanism returns to the initial position again. The support mechanism and the feeding mechanism repeat the above actions again. The pushing mechanism driving the support mechanism and the feeding mechanism ensures the sequentiality of the work, improves the safety of the present invention, and the operation process is simple. The operator only needs to operate the pushing mechanism to achieve the above purposes, and the degree of automation is relatively high, the structure is simple, and it is convenient for maintenance and upkeep. Since it is a fully mechanized process, the safety factor is relatively high, greatly reducing the waste of manpower;After the installation of the first laminated slab 4 is completed, the external driving device is started again to lift the mounting bracket 1. The mounting bracket 1 moves upward, and the bearing plate 2 remains in place under the action of the first spring 3. The upward movement of the mounting bracket 1 drives the positioning mechanism to move in the reverse direction, releasing the clamping and positioning of the wall. The external driving device readjusts the position of the mounting bracket 1 on the wall. The mounting bracket 1 moves downward again, and the positioning mechanism clamps and positions the wall again. Repeat the above actions until all the laminated slabs on the supporting mechanism are installed on the top of the wall.

[0032] Please refer to Figure 2 As a further solution of the present invention, the pushing mechanism includes a pushing plate 5. The pushing plate 5 is slidably connected to the bearing plate 2, and a first cylinder 6 for driving it to move back and forth is fixedly connected to the pushing plate 5.

[0033] When the above solution is used, the external driving device hoists the mounting bracket 1 above the wall where the laminated slab 4 needs to be installed. The external driving device moves the mounting bracket 1 downward, places the bearing plate 2 on the top of the wall where the laminated slab 4 needs to be installed. The bearing plate 2 is in contact with the top of the wall, and the bearing plate 2 remains in place under the action of the wall. The mounting bracket 1 moves downward under the action of gravity and drives the positioning mechanism to clamp and position the side of the wall. After the positioning mechanism ensures the central position of the bearing plate 2 and the mounting bracket 1 on the wall where the laminated slab 4 to be installed, the first cylinder 6 is started. The first cylinder 6 pushes the pushing plate 5 forward. The pushing plate 5 pushes the laminated slab 4 on the bearing plate 2 out of the bearing plate 2, so that the laminated slab 4 is installed on the designated top of the wall. The pushing plate 5 fine-tunes the position of the laminated slab 4 during the process of pushing the laminated slab 4 out of the bearing plate 2. The front side of the pushing plate 5 is in contact with the rear side of the laminated slab 4, ensuring the relative parallelism of the position of the laminated slab 4 relative to the bearing plate 2, and further ensuring the accuracy of the position of the laminated slab 4 and the wall.

[0034] Please refer to Figure 3 and Figure 4 As a further solution of the present invention, the positioning mechanism includes two positioning plates 7. The two positioning plates 7 are symmetrically arranged with respect to the pushing plate 5, and both of the two positioning plates 7 are slidably connected to the bottom of the bearing plate 2; second springs 8 for resetting are arranged on the side walls of the positioning plates 7, and trapezoidal blocks 9 are arranged on the sides of the positioning plates 7. The trapezoidal blocks 9 are fixedly connected to the bottom of the mounting bracket 1.

[0035] When the above solution is in use, after the external driving device hoists the mounting frame 1 to the designated position, the mounting frame 1 is slowly placed on the top of the wall where the laminated board needs to be installed. When the bearing plate 2 contacts the top of the wall, the holding position of the bearing plate 2 remains unchanged. Under the action of gravity, the mounting frame 1 continues to move downward. The downward movement of the mounting frame 1 drives the four trapezoidal blocks 9 fixedly connected to the bottom of the mounting frame 1 to move downward. The downward movement of the trapezoidal blocks 9 causes the two positioning plates 7 symmetrically arranged with respect to the pushing plate 5 to clamp and position the side wall of the wall. The positioning plate 7 keeps the bearing plate 2 at the central position of the wall, so that when the laminated board 4 is pushed out of the bearing plate 2 by the pushing plate, the position is relatively at the central position of the wall, which is convenient for the installation of the laminated board 4, improves the installation accuracy of the laminated board 4 and the wall, and enables the position between the laminated board 4 and the wall to be calibrated without secondary calibration, thereby improving the working efficiency of installing the laminated board 4; when the bearing plate 2 is not supported by the wall, the trapezoidal block 9 does not act on the positioning plate 7, and the trapezoidal block 9 maintains the supporting effect on the mounting frame 1, ensuring the stability of the mounting frame 1 when the transportation mechanism transports the laminated board to the supporting mechanism. When the external driving device hoists the mounting frame 1 away from the wall, the bearing plate 2 remains in place under the action of the first spring 3. The mounting frame 1 continues to move upward and drives the trapezoidal block 9 to move upward. Without the restriction of the trapezoidal block 9, the positioning plate 7 returns to its initial position under the action of the second spring 8, which is convenient for clamping and positioning the wall again, and ensures again that the bearing plate 2 is at the central position of the wall where the laminated board 4 needs to be installed.

[0036] Please refer to Figure 5 and Figure 6, as a further solution of the present invention, the support mechanism includes a first rotating shaft 40 and a second rotating shaft 41; the first rotating shaft 40 is located below the second rotating shaft 41, and both the first rotating shaft 40 and the second rotating shaft 41 are rotatably connected to the mounting frame 1. Both the front and rear sides of the first rotating shaft 40 are fixedly connected with first gears 11, and both the front and rear sides of the second rotating shaft 41 are fixedly connected with second gears 12; the first gears 11 and the second gears 12 located in the same vertical plane are jointly driven and connected by a chain 13, and a plurality of wedge-shaped blocks 14 evenly distributed at equal intervals are rotatably connected to the outer wall of the chain 13; a first torsion spring 15 for its reset is sleeved on the rotating shaft of the wedge-shaped block 14. A first bevel gear 16 is fixedly connected to the first rotating shaft 40, the first bevel gear 16 meshes with a second bevel gear 17, the second bevel gear 17 is fixedly connected with a first transmission telescopic shaft 10, the first transmission telescopic shaft 10 is rotatably connected to the bearing plate 2, a toothed ring 20 is arranged on the outer side of the first transmission telescopic shaft 10, the toothed ring 20 is rotatably connected to the bearing plate 2 and is concentrically arranged with the first transmission telescopic shaft 10, an internal ratchet 42 is fixedly connected to the inner ring of the toothed ring 20, the internal ratchet 42 meshes with a ratchet pawl 18, the ratchet pawl 18 is rotatably connected to the bottom end of the outer wall of the first transmission telescopic shaft 10; a second torsion spring 19 for its reset is sleeved on the rotating shaft of the ratchet pawl 18; the toothed ring 20 meshes with a first rack bar 21, and the first rack bar 21 is fixedly connected with the pushing plate 5.

[0037] When the above solution is in use, after the external driving device hoists the mounting frame 1 to the designated position, the positioning mechanism ensures that the bearing plate 2 and the mounting frame 1 are at the central position of the wall where the laminated plate 4 to be installed is located. Then, the first cylinder 6 is started. The first cylinder 6 pushes the push plate 5 to move forward. At the same time, the push plate 5 moves forward and drives the first rack bar 21 to move forward. The first rack bar 21 drives the gear ring 20 to rotate. The gear ring 20 drives the inner ratchet wheel 42 to rotate. At this time, the inner ratchet wheel 42 drives the first transmission telescopic shaft 10 to rotate through the pawl 18. The rotation of the first transmission telescopic shaft 10 drives the second bevel gear 17 to rotate. The second bevel gear 17 drives the first bevel gear 16 to rotate. The rotation of the first bevel gear 16 drives the first rotating shaft 40 to rotate. The first rotating shaft 40 drives the first gear 11 to rotate. The first gear 11 drives the second gear 12 to rotate synchronously through the chain 13. At the same time, the chain 13 drives the wedge block 14 to move downward. When the wedge block 14 moves downward, it drives the laminated plate 4 placed on the wedge block 14 to move downward. The laminated plate 4 disengages from the wedge block 14 under the action of the feeding mechanism and the laminated plate 4 falls on the feeding mechanism. At this time, the push plate 5 moves to the limit position under the action of the first cylinder 6. The first cylinder 6 drives the push plate 5 to move in the reverse direction. The reverse movement of the push plate 5 makes the first rack bar 21 fixedly connected to the push plate 5 move in the reverse direction. The first rack bar 21 drives the gear ring 20 to rotate in the reverse direction. The first transmission telescopic shaft 10 remains unchanged under the action of the pawl 18 and the second torsion spring 19. The first gear 11 and the second gear 12 remain unchanged until the push plate 5 moves to the initial position under the action of the first cylinder 6. When the push plate 5 moves forward and drives the supporting mechanism, the laminated plate 4 falls on the feeding mechanism, enabling the laminated plate 4 placed on the wedge block 14 to be automatically loaded without manual operation. The operation is simple. Only by operating the first cylinder 6 can the automatic loading of the laminated plate 4 be achieved. The pure mechanical transmission is safe and reliable, simple to operate, and has a high degree of automation, improving work efficiency.

[0038] Please refer to Figure 7 and Figure 8, as a further solution of the present invention, the feeding mechanism includes a feeding plate 22 which is rotationally and slidably connected to the mounting frame 1. The front and rear ends of the shaft of the feeding plate 22 are respectively sleeved with a first collar 23 and a second collar 24. The bottom end of the first collar 23 is fixedly connected to a first telescopic rod 25 which is slidably connected to the bearing plate 2. A first stop block 26 is arranged behind the first telescopic rod 25 and is fixedly connected to the first rack bar 21. The bottom end of the second collar 24 is fixedly connected to a second telescopic rod 27 which is slidably connected to the bearing plate 2. A third spring 28 for resetting the feeding plate 22 is fixedly connected to the feeding plate 22. A turbine 29 is fixedly connected to the rotating shaft of the feeding plate 22. A worm 30 meshing with the turbine 29 is arranged on the side of the turbine 29 and is rotationally connected to the bearing plate 2. A third gear 31 is fixedly connected to the bottom of the worm 30 and meshes with the first rack bar 21.

[0039] When the above solution is in use, after the external driving device hoists the mounting frame to the designated position, the positioning mechanism ensures that the bearing plate 2 and the mounting frame 1 are at the central position of the wall where the laminated board 4 to be installed is located. Then, the first cylinder 6 is started. The first cylinder 6 makes the pushing plate 5 move forward. The pushing plate 5 drives the first rack bar 21 to move forward. The first rack bar 21 makes the third gear 31 rotate. The third gear 31 drives the worm 30 to rotate. When the pushing plate 5 moves to the limit position, the first rack bar 21 drives the first stop block 26 to act on the first telescopic rod 25, making the first telescopic rod 25 move forward. The forward movement of the first telescopic rod 25 drives the first collar 23 to move the shaft of the feeding plate 22 and the third spring 28 fixedly connected to the shaft forward. At the same time, the turbine 29 and the worm 30 are engaged. The pushing plate 5 moves backward under the action of the first cylinder 6. The backward movement of the first rack bar 21 makes the worm 30 rotate through the third gear 31. The rotation of the worm 30 makes the engaged turbine 29 rotate. The rotation of the turbine 29 makes the shaft of the feeding plate 22 rotate, and then the feeding plate 22 rotates by a certain angle. When the pushing plate 5 is about to move to the initial position, the feeding plate 22 rotates 90 degrees. The laminated board 4 placed on the feeding plate 22 slides down onto the bearing plate 2 under the action of gravity. When the pushing plate 5 returns to the initial position under the action of the first cylinder 6, the pushing plate 5 pushes the second telescopic rod 27 backward. The backward movement of the second telescopic rod 27 drives the second collar 24 to move backward. The second collar 24 makes the feeding plate 22 move backward. At the same time, the turbine 29 and the worm 30 are disengaged. The feeding plate 22 returns to the initial state under the action of the third spring 28, facilitating re-operation. The forward and backward movement of the pushing plate 5 drives the feeding plate 22 to move forward and backward, controlling the power transmission between the turbine 29 fixedly connected to the shaft of the feeding plate 22 and the worm 30, so that only after the pushing plate 5 returns to the initial position can the feeding plate 22 place the laminated board 4 on the bearing plate 2. The feeding plate 22 slowly rotates by a certain angle during the movement of the pushing plate 5, making the laminated board 4 move downward slowly. Only after the pushing plate 5 moves to the initial position can the laminated board 4 completely fall onto the bearing plate 2, further protecting the integrity of the laminated board 4 and avoiding damage to the laminated board 4 when it falls onto the bearing plate 2.

[0040] Please refer to Figure 9 As a further solution of the present invention, the transportation mechanism includes a moving plate 32. The moving plate 32 is slidably connected to the top of the mounting frame 1. Above the moving plate 32, there is a second cylinder 33. The second cylinder 33 is fixedly connected to the mounting frame 1. The extending end of the second cylinder 33 is fixedly connected to the moving plate 32. Above the moving plate 32, there is a motor 34 fixedly connected. A steel cable 35 is wound around the output shaft of the motor 34. The other end of the steel cable 35 is fixedly connected to a hook 36.

[0041] When the above solution is in use, after the external driving device places the mounting frame 1 at the designated position, the second cylinder 33 is started. The second cylinder 33 drives the moving plate 32 to move forward. When the moving plate 32 moves to directly above the laminated plate 4, the motor 34 is started. The motor 34 lowers the steel cable 35 so that the hook 36 hooks the steel bar ring on the laminated plate 4. After the motor 34 hoists the laminated plate 4 to a certain height, the second cylinder 33 is started again. The second cylinder 33 moves the moving plate 32 backward. The backward movement of the moving plate 32 drives the motor 34 and the hoisted laminated plate 4 to move backward. After moving the laminated plate 4 above the wedge block 14, the motor 34 is controlled again to place the laminated plate 4 on the wedge block 14. The hook 36 hanging above the laminated plate 4 is removed, and the above operation is repeated again to place the laminated plate 4 on the wedge block 14 until the transportation of the laminated plate 4 is completed.

[0042] Please refer to Figure 4 As a further solution of the present invention, a number of rollers 37 are arranged in an array on the side walls of the two positioning plates 7.

[0043] When the above solution is in use, after the external driving device hoists the mounting frame 1 to the designated position, the positioning mechanism ensures that the bearing plate 2 and the mounting frame 1 are at the central position of the wall where the laminated plate to be installed is located. When the pushing plate 5 pushes the laminated plate 4 out of the bearing plate 2, in order to ensure that the pushing plate 5 pushes the laminated plate 4 to the designated position and ensures that the gap between the laminated plates 4 is within a controllable range, the position between the bearing plate 2 and the laminated plate 4 that has been pushed out is smaller than the size of the laminated plate. After the pushing plate 5 pushes out the laminated plate 4, it is ensured that the laminated plate 4 is not damaged by the extrusion of the pushing plate 5. Under the action of the reaction forces of the positioning plate 7, the roller 37 and the laminated plate 4, the bearing plate 2 moves backward, ensuring that the laminated plate 4 is not damaged during the process of the pushing plate 5 pushing the laminated plate 4 again.

[0044] Please refer to Figure 2 As a further solution of the present invention, universal balls 38 are arranged on the upper surface of the bearing plate 2, and the universal balls are connected to the upper surface of the bearing plate 2 in a rolling manner.

[0045] When the above solution is in use, when the feeding plate 22 sends the laminated plate 4 onto the bearing plate 2, in order to avoid damage to the lower surface of the laminated plate 4 when the pushing plate 5 pushes the laminated plate 4, universal balls 38 are arranged on the upper surface of the bearing plate 2, ensuring that the laminated plate 4 is less worn when being pushed out of the bearing plate 2 by the pushing plate 5 and ensuring the quality of the laminated plate 4.

[0046] Please refer to Figure 10 As a further solution of the present invention, two guiding blocks 39 are fixedly connected to the upper surface of the bearing plate 2, and the two guiding blocks 39 are symmetrically arranged with respect to the first cylinder 6.

[0047] When the above solution is in use, the external driving device hoists the mounting frame 1 to the designated position, and the positioning mechanism ensures that the bearing plate 2 and the mounting frame 1 are at the central position of the wall where the laminated panel 4 to be installed is located. To ensure that the laminated panel 4 is at the central position of the bearing plate 2, when the pushing plate 5 pushes the laminated panel 4 out of the bearing plate 2, the guiding block 39 will make a further position adjustment to the moving laminated panel 4 to ensure that the laminated panel 4 is at the central position of the bearing plate 2, so that the position between the laminated panel 4 and the wall is within the allowable range.

[0048] Working principle: First, place the mounting frame 1 at the designated position, start the conveying mechanism, and move the laminated board 4 placed on the ground onto the supporting mechanism. The setting of the supporting mechanism enables the external driving device to lift several laminated boards 4 each time. The external driving device simultaneously lifts more laminated boards 4 to the position where the laminated boards 4 need to be installed, thereby improving work efficiency. Start the external driving device to lift the mounting frame 1 and several laminated boards 4 placed on the supporting mechanism above the wall where the laminated boards 4 need to be installed. The external driving device moves downward, and the mounting frame 1 moves downward under the action of gravity, so that the wall where the laminated boards 4 need to be installed is within the positioning range of the positioning mechanism. The external driving device enables the mounting frame 1 to continue moving downward. The bottom of the bearing plate 2 slidably connected to the bottom of the mounting frame 1 contacts the top of the wall, and the position of the bearing plate 2 remains unchanged under the action of the wall. The downward movement of the mounting frame 1 drives the positioning mechanism to position and clamp the side of the wall where the laminated board needs to be installed. The positioning mechanism ensures that the bearing plate 2 is located in the middle position between the two walls, thereby ensuring that the laminated board 4 is located in the middle position of the wall where the laminated board 4 needs to be installed, controlling the position difference between the laminated board 4 and the wall within the allowable range, and improving the installation accuracy of the laminated board 4. After the bearing plate 2 is located in the middle position of the wall, start the pushing mechanism. The pushing mechanism moves forward to drive the supporting mechanism to rotate. The rotation of the supporting mechanism causes the laminated board 4 to fall onto the feeding mechanism. When the pushing mechanism moves to the limit position, the laminated board 4 falls onto the feeding mechanism. At the same time, the pushing mechanism triggers the feeding mechanism, enabling the pushing mechanism to transmit power to the feeding mechanism. The pushing mechanism moves in the reverse direction to return to the initial position. During this process, the pushing mechanism does not drive the supporting mechanism to rotate in the reverse direction. During the process of the pushing mechanism returning to the initial position, the pushing mechanism drives the feeding mechanism to send the laminated board 4 onto the bearing plate 2. At the same time, when the pushing mechanism returns to the initial position, the pushing mechanism triggers the feeding mechanism again, so that there is no longer power transmission between the pushing mechanism and the feeding mechanism. The pushing mechanism works again, pushing the laminated board 4 staying on the bearing plate 2 out of the bearing plate 2 and installing it on the top of the wall. After the installation is completed, the pushing mechanism returns to the initial position again. The supporting mechanism and the feeding mechanism repeat the above actions again. The pushing mechanism driving the supporting mechanism and the feeding mechanism ensures the sequentiality of the work, improves the safety of the present invention, and the operation process is simple. The operator only needs to operate the pushing mechanism to achieve the above purposes, and it has a high degree of automation, a simple structure, is convenient for maintenance and upkeep. Since it is a fully mechanized process, the safety factor is relatively high, greatly reducing the waste of manpower;After the installation of the first laminated slab 4 is completed, start the external driving device again to lift the mounting frame 1. The mounting frame 1 moves upward, and the bearing plate 2 remains in place under the action of the first spring 3. The upward movement of the mounting frame 1 drives the positioning mechanism to move in the reverse direction, releasing the clamping and positioning of the wall. The external driving device readjusts the position of the mounting frame 1 on the wall, and the mounting frame 1 moves downward again. The positioning mechanism clamps and positions the wall again. Repeat the above actions until all the laminated slabs on the support mechanism are installed on the top of the wall.
