Description

Technical Field

[0001] The present application relates to the technical field of building insulation boards, and in particular to a method for hoisting silicon graphene insulation boards. Background Art

[0002] As a new type of insulation material, silicon graphene insulation board features thermal insulation, high toughness and strength, non-combustibility, and low water absorption. It is used in ultra-low energy building construction and can be used as a formwork that does not require disassembly. As an embedded functional board, silicon graphene insulation board requires high surface integrity and quality. However, existing operations present the following problems:

[0003] (1) The silicon graphene insulation boards produced by manufacturers are usually transported to the site by truck in the form of multiple stacked boards, and then lifted to the material stacking site by cables and tower cranes. The traditional lifting method can easily cause deformation and damage to the edges of the top or bottom insulation boards.

[0004] (2) The specifications of the silicon graphene insulation board produced by the manufacturer are 3000mm×1200mm×90mm. Since the silicon graphene insulation board is heavier than traditional insulation materials, it is very difficult to use manual transportation and installation methods for the installation of silicon graphene insulation boards in whole or large pieces;

[0005] (3) The traditional tower crane hoisting method is to lift the material with a hook. Hooking the hook on the silicon graphene insulation board will damage the insulation board, resulting in a hole through the board, which is prone to leakage risk in the later stage;

[0006] Therefore, providing a method suitable for hoisting silicon graphene insulation board is an urgent problem to be solved in the hoisting of silicon graphene insulation board materials. Summary of the Invention

[0007] In order to prevent the cables from cutting and damaging the silicon graphene insulation boards during lifting, reduce the performance loss of the boards during transportation, and improve the project quality after the boards are installed, the present application provides a method for lifting silicon graphene insulation boards.

[0008] This application provides a method for hoisting a silicon graphene insulation board, which adopts the following technical solution:

[0009] A method for hoisting a silicon graphene insulation board comprises the following steps: arranging a plurality of foot supports around a plurality of stacked insulation boards, connecting two foot supports arranged on opposite sides of the insulation boards with an iron chain, then connecting the foot supports with a cable or pressing the insulation boards against the foot supports to bundle and fix them, and finally lifting the cables for hoisting; the foot supports comprise a first horizontal plate and a first vertical plate, the lower side of the first vertical plate is connected to the first horizontal plate, the first horizontal plate is provided with a round hole for connecting the iron chain, and the end of the iron chain is provided with a hook.

[0010] By adopting the above technical solution, a foot support is set between the plate and the lifting cable, which avoids direct contact between the cable and the plate, and prevents the ribs from squeezing the plate and causing damage to the plate after the cable is tightened during lifting. At the same time, the iron chain between the foot supports further reinforces the position of the foot supports, preventing the foot supports from sliding and wearing the plate during lifting. This lifting method can not only effectively protect the plate, but also is simple to operate, tools are easy to obtain, and it has high practical value, and has great promotion and use value.

[0011] Optionally, a second horizontal board is further connected to the upper side of the first vertical board.

[0012] By adopting the above technical solution, the first horizontal plate and the second horizontal plate of the footrest form a clamping groove, which, together with the iron chain connecting the footrests, can better fix a single plate, preventing the hoisted plate from floating away from the footrest when wind blows and causing a falling accident.

[0013] Optionally, a telescopic pipe fitting is connected between the two foot supports arranged on the same side of the insulation board, and the telescopic pipe fitting includes a sleeved outer tube and an inner tube, and the outer tube and the inner tube are respectively connected to one of the two foot supports, and the outer tube and the inner tube are both provided with a plurality of pin holes, and pins are inserted into at least two groups of overlapping pin holes in the overlapping sections of the sleeved outer tube and the inner tube.

[0014] By adopting the above technical solution, the telescopic tubes between the footrests reinforce the position of the footrests on the board to prevent the footrests from sliding. At the same time, the telescopic structure of the inner and outer tubes and the pin holes and pins enables the footrest structure to be adjusted accordingly according to the size of the board, thereby improving the applicability and practicality of the footrests.

[0015] Optionally, a cable groove for limiting the cable is provided on the outer side of the footrest.

[0016] By adopting the above technical solution, the cable duct can further prevent the cable from sliding on the foot support during hoisting, thereby improving the hoisting stability.

[0017] Optionally, a connecting seat and a connecting member are provided on the outer side surface of the first vertical plate, the connecting seat is provided with a clamping groove that crosses the outer side of the connecting seat, and two symmetrical clamping parts are provided on both sides of the connecting member, the clamping parts are inserted and snapped into the clamping groove and are used to connect the first vertical plates of two independent footrests.

[0018] By adopting the above technical solution, the connecting piece is inserted between the two first vertical plates abutting the foot supports, and the clamping portion cooperates with the clamping groove to form a firm connection between the two foot supports and integrate them into one. Two or more piles of plates can be bundled and hoisted at the same time through the foot supports and cables, thereby increasing the number of plates that can be hoisted in a single time at a limited height and improving the hoisting construction efficiency.

[0019] Optionally, the first vertical plate is provided with a guide column, a sliding member is passed through the guide column, and a spring for squeezing the sliding member is provided on the upper side of the sliding member close to the guide column.

[0020] By adopting the above technical solution, when the footrest is placed on the board, the sliding part is pressed toward the board under the action of the spring, and the sliding part and the first horizontal plate form a clamping structure, so that the footrest can be clamped and fixed on the edge of the board. It is not easy to slide or fall when connected to the iron chain, which facilitates the setting of the footrest and the bundling of the cable, and improves the operational convenience and construction efficiency.

[0021] Optionally, the sliding member includes a slider and a pressure block, the pressure block is arranged on the slider, the guide column is passed through the slider, the pressure block is slidably connected to the slider, and the end of the pressure block is provided with an avoidance slope for the pressure block to be compressed and contracted.

[0022] By adopting the above technical solution, when continuing to stack the second plate on the single plate with the footrest, the second plate is pressed on the avoidance slope, pushing the pressure block on the sliding part to slide back to one side, so that the footrest structure with the sliding part does not affect the stacking of multiple plates when in use.

[0023] Optionally, the footrest is provided with a winding post for winding up the cable and a barb for hooking the cable loop.

[0024] By adopting the above technical solution, the winding column for winding up the cable and the barb for hooking the cable loop can wind up and control the excess of the cable, and further bundle and fix the plate to improve the firmness of the lifting structure.

[0025] Optionally, a force detection device connected to the cable is provided above the insulation board, a pressure sensing pulley is provided on the upper part of the force detection device, the cable is connected to the hook of the lifting equipment after passing through the pressure sensing pulley, a coupling column is provided above the pressure sensing pulley, a pressure sensor is provided on the upper side of the coupling column, the pressure sensor is connected to a controller, and the controller is connected to a warning light.

[0026] Since the silicon graphene insulation board is an embedded functional board, the board surface is not as strong as the concrete board. During transportation, storage and handling, it should be avoided from collision, stacking of heavy objects and stepping on. Therefore, workers cannot stand on the board pile during lifting. The connection between the cable and the hook of the lifting equipment needs to be made on the ground. Therefore, a lot of cable margin will be generated during the final lifting. The general method of manually judging the length of each section of the cable under the hook and then leveling the cable length is very easy to produce errors, causing the board to be skewed during lifting. The downward side of the board is subjected to greater force, and the foot support over-squeezes the board, causing deformation and damage to the board.

[0027] Therefore, by adopting the above technical solution, when the lifting hook of the lifting equipment lifts the cable for pre-lifting, the plate has not completely left the ground, and the pressure sensing pulley on the force detection device has been squeezed by the tension of each corresponding cable segment. At this time, according to the different residual capacity of each cable segment, the tightness of each cable segment after lifting is also different, and the squeezing force on the pressure sensing pulley is also different. Therefore, the controller compares the pressure values collected by each pressure sensing pulley, determines the segment with the larger residual capacity, and lights up the corresponding warning light above the cable segment to display the status. The staff judges the residual capacity of the cable according to the warning light and adjusts the reeling to ensure that the cable segments are relatively aligned after lifting and the plate does not deflect. The pressure value comparison method can be to compare the pressure values applied to the cable segments in opposite directions, such as the north-south cable and the east-west cable. When the difference between the two pressure values applied by the cable segments in the opposite directions is greater than the set threshold, the warning light above the cable segment with the smaller pressure value lights up.

[0028] Optionally, a rotating sleeve is provided at the upper end of the coupling column, and the rotating sleeve is sleeved on the shaft provided by the force detection device. A notch is provided on the peripheral wall of the rotating sleeve, and the force detection device is provided with a baffle rod for entering and exiting the notch. The baffle rod is provided with a rack section, and the rack section is connected to an output shaft gear of a motor, and the motor is connected to the controller.

[0029] By adopting the above technical solution, when the pressure values applied by multiple cable segments received by the controller are all similar, or when they all reach the maximum pressure value, the controller controls the motor to rotate, and the gear at the output end of the motor drives the barrier rod to disengage from the rotating sleeve, unlocking the rotating sleeve, so that the pressure-sensing pulley can rotate following the cable squeezing, thereby avoiding the excessive squeezing force of the cable from damaging the pressure-sensing pulley after the plate stack completely leaves the ground after lifting, thereby improving the service life of the device.

[0030] In summary, this application includes at least one of the following beneficial technical effects:

[0031] 1. This application utilizes foot supports set between the plates and the lifting cables to bundle and lift the plates, thereby avoiding direct contact between the cables and the plates, and preventing the plates from being damaged by the ribs when the cables are tightened during lifting. The operation is simple, the tools are easily available, the practical value is high, and it has great promotion and use value.

[0032] The hoisting method of the present application can be adjusted and matched accordingly according to the number of hoisted plates. When fixing a single plate, the telescopic pipes between the foot supports are used to reinforce the position of the foot supports on the plate to prevent the foot supports from sliding. At the same time, the telescopic structure of the inner and outer tubes and the pin holes and pins can be adjusted accordingly according to the size of the plate, which has the advantages of wide applicability and high practicality.

[0042] The following is combined with Figure 1-8 This application is described in further detail.

[0043] Example 1

[0044] Reference Figure 1-3 The embodiment of the present application discloses a method for hoisting a silicon graphene insulation board 5, which can be applied to the hoisting of a pile of insulation boards 5 or the hoisting of a single insulation board 5. Specifically,

[0045] When hoisting the stacked insulation boards 5, proceed as follows:

[0046] Reference Figure 1-3 First, eight L-shaped foot supports 1 are placed around several stacked insulation panels 5, including four top panels and four bottom panels. Chains 2 are used to connect two foot supports 1 on opposite sides of the insulation panels 5, connecting the north-south foot supports 1 and the east-west foot supports 1. The insulation panels 5 are then tied and secured against the foot supports 1. Finally, cables 3 are used to lift the panels.

[0047] Reference Figure 2 The L-shaped foot support 1 includes a first horizontal plate 11 and a first vertical plate 13. The lower side of the first vertical plate 13 is connected to the first horizontal plate 11. The outer sides of the first horizontal plate 11 and the first vertical plate 13 are provided with a wire groove 14 for the limiting cable 3. The first horizontal plate 11 is provided with a circular hole 111 for connecting the iron chain 2. The iron chain 2 can be an iron chain 2 with hooks at both ends. The hook at one end of the iron chain 2 can be hung on the circular hole 111 of the foot support 1, and the other end of the iron chain 2 passes through the circular hole 111 of the other foot support 1 and is hung on the circular ring of its own iron chain 2. The foot supports 1 are connected to each other to ensure that the foot supports 1 will not slip during hoisting.

[0048] When hoisting a single insulation board 5, proceed as follows:

[0049] Reference Figure 1 First, the foot support 1 is composed of a first vertical plate 13, a first horizontal plate 11, and a second horizontal plate 12. The upper and lower sides of the first vertical plate 13 are respectively connected to the first horizontal plate 11 and the second horizontal plate 12 to form a U-shaped foot support 1. The first horizontal plate 11 and the second horizontal plate 12 are each provided with two round holes 111, one for connecting the iron chain 2, and the other for connecting the rope 3. During hoisting, four foot supports 1 are placed on both sides of a single insulation board 5, and a telescopic pipe 15 is provided between the two foot supports 1 on the same side of the insulation board 5. The telescopic pipe 15 includes a sleeved outer tube 151 and an inner tube 152. The outer tube 151 and the inner tube 152 are respectively connected to one of the two foot supports 1 on the same side. The outer tube 151 and the inner tube 152 are both provided with a plurality of pin holes 153. Pins 154 are inserted into at least two groups of overlapping pin holes 153 of the sleeved overlapping section of the outer tube 151 and the inner tube 152. Then adjust the front, back, left, and right positions of the foot support 1 according to the size of the insulation board 5. After the left and right positions are determined, use the iron chain 2 to connect the two foot supports 1 on the opposite side for fixation. After the front and back positions are fixed, use the pin holes 153 and pins 154 on the outer tube 151 and the inner tube 152 outside the foot support 1 to fix the length. Finally, use the cable 3 to connect the rope holes on the foot support 1 for lifting.

[0050] Example 2

[0051] Reference Figure 3-7 , Example 2 of the present application discloses a method for hoisting a silicon graphene insulation board 5, comprising the following steps:

[0052] Reference Figure 3-5 First, eight foot supports 1 are placed around several stacked insulation boards 5, including four top boards and four bottom boards. Chains 2 are used to connect two foot supports 1 on opposite sides of the insulation boards 5, connecting the north-south foot supports 1 and the east-west foot supports 1. The insulation boards 5 are then tied and secured against the foot supports 1, and finally, cables 3 are pulled to lift them.

[0053] The footrest 1 includes a first transverse plate 11 and a first vertical plate 13. The first vertical plate 13 is connected to the first transverse plate 11 on its underside. A cable groove 14 for a retaining cable 3 is provided on the outer sides of the first transverse plate 11 and the first vertical plate 13. In this embodiment, the cable 3 passes through the cable groove located between the first vertical plate 13 and the connecting seat 16. A circular hole 111 is provided on the first transverse plate 11 for connecting an iron chain 2. The iron chain 2 can be a chain 2 with hooks at both ends. One end of the iron chain 2 is hooked in the circular hole 111 of the footrest 1. The other end of the iron chain 2 passes through the circular hole 111 of another footrest 1 and is hooked on the ring of the iron chain 2. The connection between the footrests 1 and the first vertical plate 13 ensures that the footrests 1 do not slip during hoisting. To prevent the iron chain 2 from leaving marks on the insulation board 5 during hoisting, pads 19 can also be provided on the inner sides of the first transverse plate 11 and the first vertical plate 13 of the footrest 1.

[0054] The first riser 13 is provided with a winding post 17 for winding up the cable 3 and a barb 18 for hooking the loop of the cable 3. A connecting seat 16 and a connecting member 162 are provided on the outer side of the first riser 13. The connecting seat 16 has a snap-fitting groove 161 that runs across the outer side of the connecting seat 16. The connecting member 162 is flanked by two symmetrical snap-fitting portions 163. The snap-fitting portions 163 are inserted and snap-fitted into the snap-fitting grooves 161 and are used to connect the first risers 13 of the two independent footrests 1. The first riser 13 has a concave cavity on its inner side. A guide post 131 is provided within the cavity. A slider 134 with a sliding member 133 is inserted through the guide post 131. A pressure block 135 is provided on the slider 134. The pressure block 135 is slidably connected to the slider 134. The end of the pressure block 135 is provided with an avoidance slope 136 to allow the pressure block 135 to contract under pressure. A spring 132 is also sheathed on the outer side of the guide post 131 to compress the slider 134. When placing the footrest 1 on the first single insulation board 5, the slider 134 can be pulled upward to clamp the edge of the insulation board 5 between the slider 134 and the first cross plate 11. The slider 134 moves downward toward the first cross plate 11 under the action of the spring 132. The pressing block 135 on the slider 134 presses the insulation board 5, fixing the footrest 1 on the insulation board 5. Then, the iron chain 2 of the footrest 1 is connected and the cable 3 under the first insulation board 5 is laid. When the second insulation board 5 is stacked on the first insulation board 5, since the pressing block 135 and the slider 134 are in sliding connection, that is, a corresponding slide rail structure is provided between the pressing block 135 and the slider 134, the avoidance inclined surface 136 of the pressing block 135 is subjected to the downward pressure of the edge of the second insulation board 5, causing the pressing block 135 to move on the slider 134 away from the second insulation board 5, and the second insulation board 5 is superimposed on the first insulation board 5.

[0055] Reference Figure 6-8A force detection device 4 connected to the cable 3 is provided above the insulation board 5. The force detection device 4 includes a square box-shaped housing body 40 and a battery power supply provided in the housing body. The battery power supply is used to power the force detection device 4. A main line cavity 401 is provided in the middle of the housing body 40. Branch line cavities 402 are provided in the four circumferential directions of the main line cavity 401. A rotating shaft sleeve 43 is provided in each branch line cavity. The rotating shaft sleeve 43 is connected to the housing body 40 through a shaft rod passing through the middle. A limit stop 403 is provided on the rotating shaft sleeve 43 facing the main line cavity. The limit stop 403 is used to prevent the rotating shaft sleeve 43 from rotating toward the main line cavity 401. Specifically, the rotating shaft sleeve 43 on the left side can only rotate toward the left outer side, and the rotating shaft sleeve 43 on the right side can only rotate toward the right outer side. The rotating sleeve 43 has a telescopic cavity within it, housing a telescopically connected coupling 42. The upper end of the coupling 42 abuts a pressure sensor 46 within the cavity, while the lower end of the coupling 42 is equipped with a pressure-sensing pulley 41. The pressure sensor 46 is connected to a controller 47, which is electrically connected to four warning lights 48 on the four circumferential surfaces of the housing. A notch 431 is defined in the peripheral wall of the rotating sleeve 43. The force detection device 4 includes a lever 44 for entry and exit of the notch 431. The lever 44 includes a rack section 441, which is connected to the output shaft gear 451 of the motor 45. The motor 45 is connected to the controller 47. The cable 3 passes through the pressure-sensing pulley 41 and is connected to the hook of the lifting equipment.

[0056] Working Principle: When the lifting equipment's hook raises the cable 3 for pre-lifting, the plate hasn't completely left the ground. The four sets of pressure-sensing pulleys 41 on the force detection device 4 are already being squeezed by the outward tension of the four corresponding cable segments. Due to the varying clearances of each cable segment, the tension of the cables 3 after incomplete lifting varies, and the squeezing forces on the pressure-sensing pulleys 41 also vary. Consequently, a controller 47, based on a pre-set program and function model, compares the four pressure values collected by the four pressure-sensing pulleys 41. Specifically, it compares the pressure values applied by the opposite cable segments, for example, the north-south and east-west cables. When the difference between the two pressure values applied by the opposite cable segments exceeds a set threshold, the controller 47 illuminates a warning light 48 above the cable segment with the smaller pressure value. Staff can use this warning light 48 to determine the clearances of the cables and adjust the reeling to ensure that the cable segments are relatively aligned after lifting and the plate doesn't deflect. At the same time, when the north-south pressure difference and the east-west pressure value received and calculated by controller 47 are both less than the set threshold, or when all four pressure values reach the maximum pressure value, controller 47 controls motor 45 to rotate. The output shaft gear 451 of motor 45 drives the blocking rod 44 to disengage from the rotating sleeve 43, unlocking the rotating sleeve 43 and allowing the pressure-sensing pulley 41 located on the rotating sleeve 43 to rotate in accordance with the compression of the cable 3. This prevents the pressure-sensing pulley 41 from being damaged by the excessive compression force of the cable 3 after the plate stack is completely off the ground after lifting, thereby improving the service life of the device. In this embodiment, the four sets of pressure-sensing pulleys 41 are each controlled by two motors 45, and the output shaft gear 451 of each motor 45 is connected to the blocking rod 44 of each of the two sets of pressure-sensing pulleys 41.

[0057] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
