Description

Technical Field

[0001] This application relates to the field of splicing-type house construction equipment technology, and in particular to a plate hoisting device and hoisting method for splicing-type house construction. Background Art

[0002] A hoisting device refers to a device for lifting heavy objects in a hoisting machine. The most commonly used lifting tools in the process of lifting finished products are hooks, slings, lifting rings, etc. A splicing-type house refers to a house built by industrialized production methods, that is, the stairs, balconies, exterior walls, etc. of the house are prefabricated in a factory outside the construction site and then transported to the construction site for assembly.

[0003] When splicing a splicing-type house at the construction site, after bundling the plates with tools such as steel wires and slings, the plates are lifted by a hoisting machine, tower crane and other hoisting machinery and moved to the splicing position for splicing.

[0004] Regarding the above related technologies, the inventor believes that when hoisting the plates of a splicing-type house, the plates are bundled with steel wires, slings, etc. and then hoisted, the operation is complex, and the hoisting and unloading take a long time. Summary of the Invention

[0005] In order to improve the problem of long hoisting and unloading time when hoisting the plates of a splicing-type house, this application provides a plate hoisting device and hoisting method for splicing-type house construction.

[0006] In a first aspect, a plate hoisting device for splicing-type house construction provided by this application adopts the following technical solution:

[0007] A plate hoisting device for splicing-type house construction includes a mounting plate and a clamping assembly arranged on the mounting plate. A plurality of steel cables are arranged on the mounting plate, and a lifting ring is connected to the ends of the plurality of steel cables. The clamping assembly includes two relatively arranged clamping plates and a plurality of steel balls arranged on the clamping plates. Both of the clamping plates are inclined, and the ends of the two clamping plates away from the mounting plate are close to each other. A receiving groove for accommodating the steel balls is formed on the opposite sides of the two clamping plates. A cage for fixing the steel balls is arranged on the clamping plate. The cage is slidably arranged on the clamping plate. A discharging assembly is arranged on the clamping plate at the end of the receiving groove close to the mounting plate.

[0008] By adopting the above technical solution, when lifting a sheet, the sheet is aligned with the gap between the two clamping plates on both sides, and the two clamping plates are driven to move towards the sheet. When the sheet moves between the clamping plates, the sheet contacts the steel balls on both sides and drives the steel balls to move upward along the inclined clamping plates until the gap between the two steel balls is larger than the thickness of the sheet. At this time, the steel balls contact the two side surfaces of the sheet. When the clamping plates continue to move towards the sheet, the steel balls will not continue to move upward along the clamping plates under the action of gravity; the hoisting machinery hoists the mounting plate and the clamping plates. At this time, the clamping plates tend to move upward away from the sheet. At this time, the steel balls tend to move downward along the clamping plates under the action of gravity and the friction force between the sheet and the steel balls. Thus, the two steel balls clamp and fix the sheet between the two clamping plates; when the sheet moves to the target position and the splicing is completed, the unloading component on the clamping plate is started, so that the steel balls on the clamping plate are separated from the sheet; thus, when hoisting the sheet, it is not necessary to bind the sheet with a steel wire rope or a sling, improving the problem of long hoisting and unloading time when hoisting the sheets of a prefabricated house.

[0009] Optionally, the clamping assemblies are provided at both ends of the mounting plate.

[0010] By adopting the above technical solution, clamping assemblies are installed at both ends of the mounting plate, so that the clamping of the sheet is more stable and the hoisting process is smoother.

[0011] Optionally, a slideway is arranged on the bottom wall of the accommodating groove along the length direction of the clamping plate, and the number of the slideways is the same as that of the steel balls and is adapted to the steel balls.

[0012] By adopting the above technical solution, the steel balls move along the length direction of the slideway in the slideway, avoiding the problem of disorderly movement of the steel balls to a certain extent, and thus the problem of interference between multiple steel balls.

[0013] Optionally, the cage is formed by connecting a plurality of annular plates. The plurality of annular plates correspond to the plurality of steel balls one by one. The steel balls are rollingly embedded in the annular plates. Sliders are arranged at both ends of the cage. Chutes are arranged on both side walls of the accommodating groove along the length direction of the clamping plate. The sliders are slidably arranged in the chutes.

[0014] By adopting the above technical solution, a plurality of steel balls are all rollingly embedded in the corresponding annular plates, and both sides of the cage are slidably connected to the clamping plate through the chutes, so as to achieve the effect of facilitating the synchronous movement of a plurality of steel balls on the clamping plate. When clamping the sheet, a plurality of steel balls are all stressed, making the clamping effect better.

[0015] Optionally, rollers are rotatably arranged on the sliders.

[0016] By adopting the above technical solution, when the steel balls move, the sliders on both sides of the cage are in rolling fit with the chute through the rollers, so that the movement of the cage is smoother.

[0017] Optionally, the unloading assembly includes an electromagnet, and the electromagnet is arranged on the clamping plate and located at one end of the receiving groove close to the mounting plate.

[0018] By adopting the above technical solution, when unloading the plate between the two clamping plates on both sides, the electromagnet is started, and the electromagnet generates a suction force on the steel balls, and the steel balls move along the receiving groove towards the electromagnet, so that the steel balls are separated from the clamping plate, achieving the effect of facilitating the unloading of the plate between the two clamping plates on both sides.

[0019] Optionally, a cavity is formed in the mounting plate, the clamping plate is slidably arranged in the cavity, and a plurality of cylinders are arranged in the cavity, and the end of the piston rod of the cylinder is connected to the clamping plate.

[0020] By adopting the above technical solution, the clamping plate is slidably installed in the cavity. When hoisting plates of different thicknesses, the distance between the two clamping plates on both sides is adjusted by the cylinders, so that the hoisting device has a wider application range.

[0021] In a second aspect, a method for hoisting a plate for the construction of a spliced house building provided by the present application adopts the following technical solution:

[0022] A method for hoisting a plate for the construction of a spliced house building includes the following steps:

[0023] S1: Connect the hoisting machine with the lifting ring; S2: Vertically place the plate, drive the mounting plate to move through the hoisting machine, move the two clamping plates on both sides until the gap between the two clamping plates on both sides is aligned with the plate, drive the two clamping plates to move downward and make the plate located between the two clamping plates on both sides; S3: Drive the mounting plate to lift through the hoisting machine to hoist the plate; S4: After the plate is hoisted and installed in place, start the unloading assembly, and the plate is separated from the two clamping plates on both sides.

[0024] By adopting the above technical solutions, during the hoisting process of the sheet material, the operator first connects the hook of the hoisting machinery to the lifting ring, drives the mounting plate to move through the machinery, aligns the gap between the two clamping plates with the clamping plates, and then drives the two clamping plates to move towards the sheet material, so that the sheet material is located between the two clamping plates. When the two clamping plates move towards the sheet material, the steel balls move upward along the inclined direction of the clamping plates until the distance between the steel balls on both sides is larger than the thickness of the sheet material. At this time, the steel balls on both sides are in contact with the two side surfaces of the sheet material; the hoisting machinery drives the mounting plate and the clamping plates to lift. At this time, the steel balls on both sides tend to move downward under the action of gravity and the driving of the sheet material, so as to clamp the sheet material between the two clamping plates, and the sheet material moves with the hoisting of the mounting plate; after the sheet material is hoisted and installed in place, the unloading component is started to separate the steel balls from the sheet material, so that the sheet material is separated from the two clamping plates, and the hoisting of the sheet material is completed without bundling with steel wires or slings.

[0025] In summary, the present application includes at least one of the following beneficial technical effects:

[0026] 1. The sheet material is clamped and fixed by the steel balls between the clamping plates, and there is no need to bundle the sheet material with steel wires or slings for hoisting, which improves the problem of long hoisting and unloading time when hoisting the sheet material of the prefabricated house.

[0027] 2. Structures such as clamping blocks and pins that are convenient for splicing may be processed on the side surface of the sheet material of the prefabricated house. When bundling the sheet material with steel wires or slings, the splicing structures on the side surface of the sheet material are easily damaged. By clamping and hoisting the sheet material with the clamping plates, there is no need to bundle the sheet material, which avoids the damage of the splicing structures on the sheet material to a certain extent.

[0028] 3. A cage is slidably installed on the clamping plate. The cage is slidably connected to the two side walls of the receiving groove. The steel balls are rollingly embedded on the cage. When the sheet material moves relative to the clamping plate, multiple steel balls move synchronously on the clamping plate, so that when clamping the sheet material, multiple steel balls are all stressed, and the clamping effect on the sheet material is good.

[0029] 4. The sheet material is unloaded by the electromagnet. When the sheet material is hoisted and installed in place, the electromagnet is started. The electromagnet adsorbs the steel balls and drives the steel balls to move towards the electromagnet along the inclined surface of the clamping plate, so as to separate the steel balls from the sheet material, achieving the effect of convenient unloading.

[0036] The following further describes the present application in detail Figures 1-4 in conjunction with the attached drawings.

[0037] The embodiment of the present application discloses a plate hoisting device for the construction of a spliced house building.

[0038] Referring to Figure 1 and Figure 2 , a plate hoisting device for the construction of a spliced house building includes a mounting plate 1 and a clamping assembly 2 arranged on the mounting plate 1. The mounting plate 1 is a rectangular plate body, and the clamping assemblies 2 are installed at both ends of the mounting plate 1. A through hole for reducing the weight of the mounting plate 1 is provided in the center of the mounting plate 1. A steel cable 3 is fixedly connected to the side of the mounting plate 1 away from the ground, and the steel cable 3 is installed at the four corners of the mounting plate 1. The ends of the four steel cables 3 are all connected to the same suspension ring 31. The clamping assembly 2 includes two relatively installed clamping plates 4 and a plurality of steel balls 5 installed on the clamping plates 4. The two clamping plates 4 are both inclinedly installed, and the ends of the two clamping plates 4 away from the mounting plate 1 are close to each other. Receiving grooves 41 are provided on the opposite side surfaces of the two clamping plates 4. The receiving grooves 41 are rectangular grooves, and a plurality of steel balls 5 are installed in the receiving grooves 41. The plurality of steel balls 5 are connected to each other through a cage 51, and the cage 51 is slidably connected to the clamping plate 4. An unloading assembly 6 is also installed on the clamping plate 4, and the unloading assembly 6 is located at one end of the receiving groove 41 close to the mounting plate 1.

[0039] The distance between the ends of the two clamping plates 4 is greater than the thickness of the plate. When the steel balls 5 on the two clamping plates 4 are all at the lowest end of the receiving groove 41, the distance between the steel balls 5 on the two clamping plates 4 is smaller than the thickness of the plate. As the steel balls 5 move obliquely upward along the inclination angle of the clamping plate 4, the distance between the steel balls 5 on the two clamping plates 4 continuously increases.

[0040] When hoisting the board at the construction site, connect the hook of the hoisting machinery with the lifting ring 31, drive the mounting plate 1 to move until the gap between the two clamping plates 4 is aligned with the board, and then drive the mounting plate 1 to move towards the board. When the board enters between the two clamping plates 4, the steel balls 5 on the two clamping plates 4 contact the board and move obliquely upward along the receiving groove 41. When the distance between the steel balls 5 on the two clamping plates 4 is greater than the thickness of the board, the steel balls 5 on the two clamping plates 4 contact the two side surfaces of the board. Lift the mounting plate 1, and the board has a tendency to move away from the mounting plate 1 under the action of gravity. The steel balls 5 on the two clamping plates 4 have a tendency to move away from the mounting plate 1 under the action of their own weight and the friction force with the board. Thus, the steel balls 5 on the two clamping plates 4 clamp the board between the two clamping plates 4.

[0041] Refer to Figure 2 and Figure 3 As shown in FIGS. 4 and 5, a plurality of slideways 411 are formed in the bottom wall of the receiving groove 41 along the length direction of the clamping plate 4. The number of the slideways 411 is the same as the number of the steel balls 5 on the clamping plate 4. The steel balls 5 correspond to the slideways 411 one by one and the slideways 411 are adapted to the steel balls 5. The cage 51 is formed by sequentially connecting a plurality of annular plates 511. The inner wall of the annular plate 511 is processed with an arc. The steel balls 5 are embedded in the annular plate 511 and the steel balls 5 can rotate relative to the annular plate 511. Sliders 512 are connected to both ends of the cage 51. Slide grooves 42 are formed in both side walls of the receiving groove 41 along the length direction of the clamping plate 4. The sliders 512 are slidably mounted in the slide grooves 42. Rollers 5121 are rotatably mounted on the sliders 512, and the rollers 5121 are in rolling connection with the bottom wall of the slide grooves 42.

[0042] When the steel balls 5 move, under the action of the cage 51, the plurality of steel balls 5 on the clamping plate 4 move synchronously. Both sides of the cage 51 are slidably connected to the clamping plate 4 through the sliders 512, so that the steel balls 5 always move in the receiving groove 41. When clamping and fixing the board, the plurality of steel balls 5 are located on the same horizontal plane and the plurality of steel balls 5 are stressed simultaneously, so that the clamping effect is better.

[0043] Refer to Figure 2 As shown in FIGS. 6 and 7, the unloading assembly 6 includes an electromagnet 61. The electromagnet 61 is mounted on the clamping plate 4 and is located at one end of the receiving groove 41 close to the mounting plate 1. When a board is clamped and fixed between the two clamping plates 4, after the board is hoisted and installed in place, start the electromagnet 61. The electromagnet 61 generates a suction force on the plurality of steel balls 5 and drives the steel balls 5 to move obliquely upward along the slideways 411. Thus, the steel balls 5 are separated from the board, and the board is unloaded from between the two clamping plates 4.

[0044] Refer to Figure 2 and Figure 4, a cavity 11 is provided in the mounting plate 1. The cavity 11 is a cuboid. On one side surface of the mounting plate 1 facing the clamping plate 4, a plurality of adjusting holes 13 are provided in parallel and at equal intervals. The adjusting holes 13 communicate with the cavity 11. A plurality of connecting rods 43 are installed at the top of the clamping plate 4. A cross beam 44 is installed in the cavity 11. The connecting rods 43 extend into the cavity 11 through the adjusting holes 13 and are fixedly connected to the cross beam 44. A plurality of cylinders 12 are installed in the cavity 11. The cylinder block of the cylinder 12 is fixedly connected to the side wall of the cavity 11, and the piston rod of the cylinder 12 is fixedly connected to the cross beam 44.

[0045] When hoisting plates with different thicknesses, start the cylinder 12. The piston rod of the cylinder 12 extends or retracts, driving the cross beam 44 to slide in the cavity 11, thereby adjusting the distance between the two opposite clamping plates 4. Adjust the two clamping plates 4 so that the distance between the ends of the two clamping plates 4 away from the mounting plate 1 is greater than the thickness of the plate, and at the same time, the distance between the steel balls 5 on the two clamping plates 4 is less than the thickness of the plate.

[0046] The implementation principle of a plate hoisting device for splicing house construction in an embodiment of the present application is as follows: When hoisting a plate for splicing house construction, the mounting plate 1 is driven by a hoisting machine to move until the two clamping plates 4 on both sides are directly opposite to the plate, and the mounting plate 1 is driven to move towards the plate; when the plate enters between the two clamping plates 4, the steel balls 5 move upward along the inclination angle of the clamping plate 4 under the action of the plate. When the distance between the steel balls 5 on the two clamping plates 4 is greater than the thickness of the plate, the steel balls 5 on the two clamping plates 4 are in contact with the two side surfaces of the plate; the mounting plate 1 is driven to lift, and the steel balls 5 tend to move downward along the inclined surface of the clamping plate 4 under the action of gravity and the driving of the plate, and the steel balls 5 on the two clamping plates 4 clamp the plate; when the hoisting and installation of the plate are completed, start the electromagnet 61, and the electromagnet 61 adsorbs the steel balls 5 and drives the steel balls 5 to move upward along the inclined surface of the clamping plate 4 to separate the plate from the two clamping plates 4.

[0047] The embodiment of the present application also discloses a method for hoisting plates for splicing house construction:

[0048] A method for hoisting plates for splicing house construction includes the following steps:

[0049] S1: The operator connects the hook of the hoisting machine to the lifting ring 31, and places the plate in a vertical state to facilitate subsequent clamping and hoisting of the plate;

[0050] S2: Start the cylinder 12. The piston rod of the cylinder 12 extends or retracts, driving the two clamping plates 4 on both sides to approach or move away from each other, adjusting the distance between the two clamping plates 4 so that the distance between the lowest ends of the two clamping plates 4 is greater than the thickness of the plate to be hoisted, and at the same time, the distance between the steel balls 5 on the two clamping plates 4 is less than the thickness of the plate to be hoisted;

[0051] S3: The operator starts the hoisting machinery, drives the lifting device to move, and moves it until the gap between the two clamping plates 4 on the mounting plate 1 is directly opposite to the plate material.

[0052] S4: Start the hoisting machinery, drive the lifting device to move towards the plate material, and the plate material enters between the two clamping plates 4 through the gap between the two side plates.

[0053] S5: After the steel balls 5 on the two clamping plates 4 come into contact with the two side surfaces of the plate material, then drive the mounting plate 1 towards the plate material until the steel balls 5 on the two clamping plates 4 come into contact with the two side surfaces of the plate material.

[0054] S6: Start the hoisting machinery, drive the lifting device to lift. At this time, the steel balls 5 on the two clamping plates 4 tend to move downward along the inclined surface of the clamping plate 4, so that the steel balls 5 on the two clamping plates 4 clamp and fix the plate material, and the plate material rises with the rise of the mounting plate 1.

[0055] S7: After the plate material is hoisted to the installation position by the hoisting machinery, start the electromagnet 61. The electromagnet 61 generates a suction force on the steel ball 5 and drives the steel ball 5 to move along the inclined surface of the clamping plate 4 towards the electromagnet 61, and the steel ball 5 is separated from the plate material.

[0056] S8: The operator starts the hoisting machinery, moves the lifting device outside the plate material, turns off the electromagnet 61, the steel ball 5 moves to the lowest end of the receiving groove 41 under the action of gravity, moves the lifting device to the position of the plate material to be hoisted, and performs subsequent hoisting operations.

[0057] The above are all the preferred embodiments of the present application, and do not limit the protection scope of the present application accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
