Description

Technical Field

[0002] Construction projects involve a large number of electromechanical equipment, which require a lot of lifting equipment. The traditional lifting method has low lifting efficiency and a tight construction schedule.

[0003] Lifting holes are usually reserved on building floors to facilitate the vertical transportation of large equipment or heavy materials. These lifting holes are designed at key locations of the building structure to provide sufficient space and support for equipment lifting operations. However, the existence of lifting holes also brings certain safety hazards, especially in the non-lifting stage, it will become a potential risk point for people and objects to fall.

[0004] In order to reduce risks, the lifting port is usually covered with a cover when it is not in use, and a guardrail is installed around the lifting port to form an isolation protection. This protective measure can effectively prevent people from accidentally approaching the lifting port and reduce the possibility of falling. However, this practice also has some hidden dangers. First, the cover and guardrail need to be inspected and maintained regularly to ensure that they can be removed smoothly during the lifting operation and will not be accidentally loosened. Secondly, when lifting operations are required, the cover and guardrail must be removed. This process involves the collaboration of multiple people and needs to be carried out strictly in accordance with the operating procedures. The environment around the lifting port and whether the operator's protection awareness is in place will directly affect the safety of the operation.

[0005] In addition, the hoisting process is complicated and involves collaboration among multiple parties. Before hoisting, construction workers need to conduct a comprehensive inspection of the hoisting port to ensure that the hoisting equipment and required materials meet the specifications, and closely monitor every link of the hoisting process during the hoisting operation to avoid dangers caused by negligence. At the same time, the frequent removal and installation of guardrails and cover plates during the hoisting process also increases the complexity of the operation and the workload of personnel.

[0006] Therefore, in order to effectively reduce the safety risks brought by the lifting opening, there is an urgent need for a vertical transfer tooling and construction method for large-scale public building renovation equipment that can effectively prevent the risk of falling and can be quickly opened and restored during lifting operations.

[0070] The present invention also provides a method for preparing and constructing a construction tool for vertically transporting large equipment for public building renovation:

[0071] Preliminary preparation work:

[0072] (1) Preparation work at the basement equipment lifting port: open a lifting port on the lifting floor 100, dismantle the facade at the lifting port, remove the greenery, shrubs and green grass on the facade side, take temporary hardening measures on the ground, and lay a roadbed box to meet the strength requirements of the equipment transfer route.

[0073] (2) Making a cover enclosure device 400, including a frame 401 and an integrated enclosure 405. Two sets of integrated enclosures 405 are connected to the frame 401 by hinges 403. The frame 401 is made of channel steel. The integrated enclosure 405 includes a steel plate, a main keel 402, and a secondary keel 404. The middle of the steel plate is reinforced with the main keel 402, and the surroundings are reinforced with the secondary keels 404.

[0074] (3) Make a 300-meter hoisting steel platform, using H-steel, with a 5mm steel plate on the bottom, and a 1500mm high guardrail around it for protection, and a reliable wire mesh. The length and width of the hoisting steel platform must meet the dimensions of all equipment in the project. The platform is checked according to the steel beam load in both the length and width directions, and can only be used after safety is calculated and checked. An electronic level is installed on the hoisting steel platform to observe and adjust the levelness of the hoisting steel platform.

[0075] (4) Unloading the hoisting steel platform 300. Use a 25t truck crane to unload the hoisting steel platform 300. The hoisting steel platform 300 has a deadweight of 4t and a hoisting working radius of 8m. Then, tow it to the vicinity of the hoisting port. The truck crane can only be used after calculation and verification of safety.

[0076] (5) Arrange the winch. Define the hoisting floor 100 as the first floor, and the upper floor 500 above the hoisting port as the second floor. Place two H-shaped steels of HW250*250*9*14 on the second floor slab, and drill eight floor holes of ф100 on the side to serve as the lowering points. The actual length of the H-shaped steel is 9 meters, and the effective calculated length as a simply supported beam is 7 meters. The lower floor 200 below the hoisting port is defined as the basement.

[0077] (6) The distance between the two main lifting points of the lifting component 501 and the leveling component 502 is 3.5 meters. Four 5-ton slow winches are used for hoisting. The 5-ton winches are used for hoisting subsequent heavier equipment. The winches are arranged in the basement, of which two winches are used as the lifting component 501 to vertically lift the steel platform 300, and two winches are used to adjust the horizontality of the hoisted steel platform 300.

[0078] The wire rope on the H-steel placed on the second floor is 6*37-FC-1770-ф24, with 2 loops. The contact position between the wire rope and the H-steel is protected by an angle wrap to prevent stress concentration at the quick mouth from causing breakage. The movable pulley block uses HQD3-10, and the single winch has a total of 8 running ropes. The specification of the winch running rope is 6*37-FC-1770-ф20.

The crane scale can be operated by wireless remote control to achieve remote control. It is installed on the movable pulley block through the hook. During the hoisting process, pay attention to the weight reading and control the weight.

[0079] In the initial state, the side baffles and the folding baffles of the integrated enclosure 405 on the covering enclosure device 400 are in a folded state, and the two sets of integrated enclosures 405 are in a closed state; the hoisting floor 100 is defined as the first floor, the upper floor of the hoisting floor 100 is defined as 500 as the second floor, and the lower floor of the hoisting floor 100 is defined as 200 as the basement.

[0080] like Figures 4 to 8 As shown, the construction method is as follows:

[0081] Step S1: Open the lifting port: When lifting is required, the covering enclosure device 400 installed on the lifting port on the first floor is opened, and the connection constraints of the two sets of integrated enclosures 405 are first released through the locking device, and the side baffles connected by the three steel plates of the two sets of integrated enclosures 405 are opened separately, and then the folding steel plates connected at both ends of the side baffles are unfolded through hinges.

[0082] The two side baffles are vertically fastened to the frame 401 by bolts respectively, and then the two folded steel plates at one end of the two side baffles are connected to form a folded baffle, and the folded baffle is vertically fastened to the frame 401 by bolts.

[0083] The two folding steel plates at the other ends of the two side baffles are opened outwards as doors for introducing the hoisting steel platform 300.

[0084] Step S2: Prepare the hoisting steel platform 300: Use a 25t truck crane to unload the hoisting steel platform 300, the hoisting steel platform 300 has a deadweight of 4t and a hoisting working radius of 8m, and then tow it to the vicinity of the hoisting port.

[0085] Step S3: hoisting the steel platform 300: a hoisting assembly 501 and a leveling assembly 502 are set on the second floor, and four winches are set in the basement. Two winches are used as hoisting assemblies 501 to vertically hoist the steel platform 300, and the other two winches are used as leveling assemblies 502 to adjust the horizontality of the hoisted steel platform.

[0086] The hoisting assembly 501 and the leveling assembly 502 slowly move the hoisting steel platform 300 to the left close to the door direction of the covering enclosure device 400, and finally hoist the hoisting steel platform 300 to the middle position of the hoisting opening, adjusting it to a state for vertical hoisting.

[0088] At the same time, during the hoisting process, the electronic level 302 of the hoisting steel platform is observed and fed back to the control system. The control system timely adjusts the level of the hoisting steel platform 300 through the leveling component 502 to keep it in a horizontal state at all times.

[0089] By loosening the running ropes of the four sets of winches of the hoisting assembly 501 and the leveling assembly 502, the hoisting steel platform 300 is vertically lowered to the ground in the basement, and the protective railing on one side of the hoisting steel platform 300 is opened to guide the equipment.

[0090] Step S4: Equipment in place: The basement equipment is pushed into the center of the hoisting steel platform 300, and four rope tighteners are used to tie the equipment firmly to the hoisting steel platform 300. The guardrail on one side of the hoisting steel platform 300 is closed, and the guardrails around the hoisting steel platform 300 are checked to see if they are vertically fastened to prevent the equipment from falling; the winch and wire rope are arranged on both sides of the width direction of the hoisting steel platform, and will not interfere with the hoisting steel platform and the equipment transportation line. After the equipment is lifted up by the road lifting machine, four tanks 301 with tank wheels are placed at the bottom for translation. The translation power source is provided by a 3t forklift. When hoisting equipment of more than 10t, after the equipment is on the hoisting steel platform, the road lifting machine is used to lift the equipment to take out the tank, and the road wood is used to pad it.

[0091] Step S5: The hoisting steel platform 300 of the hoisting belt equipment: Use the winch to slowly hoist the hoisting steel platform 300 upwards through the hoisting component 501 and the leveling component 502; observe the electronic level 302 during the hoisting process, adjust the level of the hoisting steel platform in time, keep it level, and lift the equipment to the height of the first floor.

[0092] Step S6: moving out the equipment: one end of the hoisting steel platform 300 is connected to two hand hoists 101, and the hand hoists 101 are used to ensure that the hoisting steel platform 300 does not shake when it is slowly moved to the right to move out of the covering enclosure device 400 in step S6.

[0093] A winch is installed on the first floor. A 1t winch is used to provide traction to slowly drag the equipment out of the hoisting steel platform 300 from the opening. When hoisting equipment above 10t, a protection plan is added. After the hoisting steel platform is hoisted, two HW250*250*9*14 H-steels are placed across the hoisting opening to support the bottom of the hoisting steel platform 300.

[0094] When there is a height difference between indoor and outdoor, that is, the indoor floor is high and the outdoor floor is low, it is necessary to set up a steel box beam platform outdoors in advance, set the height of the steel box beam platform according to the outdoor height, and stack the steel box beams layer by layer until they are the same height as the outdoor height. Once the above is completed, the transportation is completed.

[0095] Loading and transporting away. After completing the above steps, the equipment arrives outdoors, and then a 100t truck crane is used to lift it onto the truck and then drive away. The truck crane can only be used after calculation and verification of safety.

[0096] The following is a detailed description with specific parameters:

[0097] Project description: The basement equipment hoisting of this project faces difficulties. There is no construction ramp, no outdoor hoisting port, and no large freight elevator. The equipment needs to be hoisted from the basement to the first floor, and a hoisting port is opened on the first floor. The maximum weight of the equipment is an ice storage tank of 16t.

[0098] The vertical transfer tooling for large equipment in public building renovation mainly includes lifting port covering and enclosure devices, lifting steel platforms, winch lifting systems, etc.

[0099] Furthermore, the invention provides a vertical transfer tool for large-scale equipment in public building renovation, and a hoisting port sealing and enclosure device such as Figure 1 As shown, it includes a frame and a baffle. The baffle and the frame are connected by hinges. The frame is made of channel steel. The baffle is composed of a steel plate, a main keel, and an auxiliary keel. The steel plate is reinforced with the main keel around it and the auxiliary keel in the middle. The frame is installed at the hoisting port. The baffle is in a folded state when not hoisted. It is opened when hoisted. There are baffles on all four sides of the frame, three of which are fixed with bolts, and the other baffle is a door that can be opened outwards.

[0100] Furthermore, the invention provides a vertical transfer tool for large-scale equipment for public building renovation, a hoisting steel platform such as Figure 3 As shown, it is made of H steel, with 5mm steel plate on the bottom, 1500mm high guardrails around it, and reliable wire mesh. The length and width of the hoisting steel platform must meet the size of all equipment in the project. The platform is checked according to the steel beam load in both length and width directions, and can only be used after safety is calculated and checked. An electronic level is installed on the hoisting steel platform to observe and adjust the levelness of the hoisting steel platform.

[0101] For example Figure 3As shown, the effective volume of the hoisting steel platform is 6 meters long and 3.5 meters wide, and its deadweight is 4 tons. The platform is checked according to the steel beam load in both length and width directions, and the design load is 1T / m 2 , total area 21m 2 , load limit 20 tons.

[0139] Furthermore, the vertical transfer tooling for large-scale equipment in public building renovation provided by the present invention and the configuration of the hoisting system of the winch are as follows: Figure 4As shown, it includes winches, hoisting components, leveling components, etc. Hoisting components 501 and leveling components 502 include H-shaped steel, movable pulleys, wire ropes, running ropes, etc. H-steel is placed on the second floor slab above the hoisting port. As the main load-bearing component of hoisting, the specifications are HW250*250*9*14, the material is Q235, and 8 floor holes of ф100 are drilled on the side to be used as the lowering points. H-steel can only be used after safety verification by calculation. The winch uses four 5t slow winches. The hoisting capacity of the winch must meet the maximum weight of the project equipment. The winch is arranged in the basement, two of which are used to hoist and lift the hoisting steel platform, and two winches are used to adjust the level of the hoisting steel platform. The wire rope on the H steel placed on the second floor is 6*37-FC-1770-ф24, which is wrapped around 2 times. The contact position between the wire rope and the H-steel is protected by an angle wrap to prevent stress concentration at the quick mouth from causing fracture. The movable pulley block adopts HQD3-10, and the single winch has a total of 8 running ropes, and the specification of the winch running rope is 6*37-FC-1770-ф20. The winch, wire rope, lifting rigging, etc. can only be used after safety verification by calculation. The crane scale consists of a high-definition LCD screen, high-precision sensors, hooks, rings, etc. The weight reading is displayed on the high-definition LCD screen. The crane scale can be operated by wireless remote control to achieve long-distance control. It is installed on the movable pulley block through the hook. A group control wireless switch is installed on the four winches to achieve one remote control to control multiple winches at the same time to ensure synchronization.

[0140] For example Fig.10 As shown, H steel, its cross-sectional area A = 91.43 cm 2 , moment of inertia I = 10700cm 4 , bending section coefficient W = 860cm 3 The mechanical model of the H-shaped steel is shown in the figure below, l = 7m, a = 1.75m; F is the total root force of the winch, and its value is F = 1.1*0.25*(160+40)kN = 55kN.

[0149] The flexural strength meets the requirements.

[0150] The shear strength meets the requirements.

[0151]

[0152] The stiffness meets the requirements.

[0153] The deadweight of the hoisting steel platform is 4t, and the maximum mass of the equipment is 16t, totaling 20t, or 200kN. Two winches are used for lifting, and the force on each winch is considered to be an unbalanced coefficient of 1.1, so F 单 =1.1*100kN=110kN.

[0154] The winch wire rope is 6*37-FC-1770-ф20, and the comprehensive labor saving coefficient when running 8 tracks and 1 guide is 0.149. Therefore, the running rope tension of a single winch is S=α*F=16.4kN. The safety factor of the wire rope is K=234 / 16.4=14.2>[K]=8, which is safe.

[0155] According to the tension of the running rope, the guide wheel is selected as 5-ton level for a single door; the 10-ton level is selected for the 3-door pulley group.

[0156] The steel wire rope wrapped with H steel is 6*37-FC-1770-ф24 with 2 windings. The breaking force of a single wire is 336kN. After winding 2 windings, it is simplified to 4 single wires. Considering the reduction factor of 0.8, the breaking force is 0.8*4*336=1075kN. The safety factor of the steel wire rope is K=1075 / 55=19.5>[K]=8, which is safe.

[0157] The lifting rigging connecting the lifting steel platform uses 4 6*37-FC-1770-ф28 riggings, each of which is tied and has a breaking force of S 破 =336kN. Q = 55kN. Working coefficient K = S 破 / Q 计 =458 / 55=8.3>[K]=8, safe. The connecting shackle is 10 ton grade.

[0158] The anchor points of the guide wheel and winch are fixed to the concrete floor with four M12 expansion bolts. The tensile design value is 4*10.98=43.92kN, and the shear design value is 4*7.56=30.24kN. According to the running rope tension of 16.4kN, its vertical and horizontal components must be less than 16.4kN. Safety.

The length and width of the hoisting steel platform must meet the dimensions of all equipment in the project. The platform is checked according to the steel beam load in both length and width directions, and can only be used after safety is calculated and checked. An electronic level is installed on the hoisting steel platform to observe and adjust the levelness of the hoisting steel platform.

[0164] (5) Unloading the hoisted steel platform. Use a 25t truck crane to unload the hoisted steel platform. The hoisted steel platform has a deadweight of 4t and a hoisting working radius of 8m. Then, tow it to the vicinity of the hoisting port. The truck crane can only be used after calculation and verification of safety.

[0165] Example: A 25t truck crane is used with a 17.2m main boom and an 8m working radius, and its rated lifting capacity is 10.2t.

[0166] Q 计 =K*(W+F)=1.1*4+1=5.5t

[0167] Where Q 计 To calculate the load, K is the dynamic load factor, which is 1.1, W is the mass of the equipment, and F is the mass of the hook and rigging. The calculated load is less than the rated lifting capacity, which is safe.

[0168] (6) Arrange the hoisting system of the winch. Two H-shaped steels of HW250*250*9*14 are placed on the second floor slab above the lifting port, and eight floor holes of ф100 are drilled on the side to be used as the lowering lifting points. The actual length of the H-shaped steel is 9 meters, and the effective calculated length as a simply supported beam is 7 meters. The distance between the two main lifting points is 3.5 meters. Four 5-ton slow winches are used for the winch. The 5-ton winch is selected for the purpose of lifting subsequent heavier equipment. The winches are arranged in the basement, two of which are used for vertical lifting of the steel platform, and two winches are used to adjust the horizontality of the lifting steel platform. The wire rope clamped on the H-steel placed on the second floor is 6*37-FC-1770-ф24, and is wrapped twice. The contact position between the wire rope and the H-steel is protected by a wrap angle to prevent stress concentration at the quick mouth from causing breakage. The movable pulley block adopts HQD3-10, and the single winch has a total of 8 running ropes, and the specification of the winch running rope is 6*37-FC-1770-ф20. The crane scale is composed of a high-definition LCD screen, high-precision sensors, hooks, rings, etc. The weight reading is displayed on the high-definition LCD screen. The crane scale can be operated by wireless remote control to achieve long-distance control. It is installed on the movable pulley block through the hook. During the hoisting process, pay attention to the weight reading and control the weight.

[0169] (7) Lift the steel platform into place. Use two 2t hoists to protect the right side of the steel platform to ensure that the steel platform moves slowly to the left without shaking. The steel platform is slowly lifted to the left into a vertical state, forming a Figure 5 As shown. Use two winches to vertically hoist the steel platform. Use two winches to adjust the level of the hoisted steel platform. During the hoisting process, observe the electronic level of the hoisted steel platform and adjust the level of the hoisted steel platform in time to keep it level. Then loosen the winch wire rope and lower the hoisted steel platform to the basement. Figure 5 As shown. So far, the preparation work for equipment hoisting is completed.

[0170] (8) The equipment is positioned on the hoisting steel platform. After the hoisting steel platform is positioned, the basement equipment is moved horizontally onto the hoisting steel platform. The winch and running rope are arranged on both sides of the hoisting steel platform in the width direction, and will not interfere with the hoisting steel platform and the equipment transportation route. After the equipment is lifted up by a road-lifting machine, four tanks are placed at the bottom for horizontal movement. The horizontal movement power source is provided by a 3t forklift.

[0171] (9) Equipment lifting. The equipment is loaded onto the lifting steel platform and placed in the center, avoiding eccentric placement as much as possible. Use 4 rope tighteners to tie the equipment firmly to the lifting steel platform. When lifting equipment above 10 tons, use a road lifter to lift the equipment to remove the tank car after the equipment is on the lifting steel platform, and use road wood to place it. Then start lifting. Use two winches to vertically lift the steel platform through the lifting components. Use two winches to adjust the level of the lifting steel platform through the leveling components. During the lifting process, observe the electronic level of the lifting steel platform, adjust the level of the lifting steel platform in time, keep it level, and lift the equipment to the height of one floor. Then use two 2t hoists to pull the lifting steel platform sideways. Ensure that when the equipment is moved horizontally out of the lifting steel platform, the lifting steel platform will not shake left and right. Then set up a winch on the first floor, use a 1t winch to provide traction, and slowly drag the equipment out of the lifting steel platform. In addition, when lifting equipment above 10 tons, add a protection plan. After the hoisting steel platform is hoisted, two HW250*250*9*14 H-steels are placed across the hoisting port to support the bottom of the hoisting steel platform. If there is a height difference between indoor and outdoor, that is, the indoor floor is high and the outdoor floor is low, it is necessary to set up a steel box beam platform outdoors in advance, set the height of the steel box beam platform according to the outdoor height, and stack the steel box beams layer by layer to the same height as the outdoor.

[0172] (10) Loading and transporting away. After completing the above steps, the equipment arrives outside, and then a 100t truck crane is used to lift it onto the truck and then drive away. The truck crane can only be used after calculation and verification of safety.

[0173] Example: The lifting working radius is 12m. The working condition of a 100-ton truck crane is a 25.8m main arm, 23t counterweight, and a rated lifting capacity of 28t when the working radius is 12m. Check Q based on the maximum mass of the equipment, which is an ice storage tank of 16t. 计 =K*(W+F)=1.1*16+2=19.8t.

[0174] Where Q 计 To calculate the load, K is the dynamic load factor, which is 1.1, W is the mass of the equipment, and F is the mass of the hook and rigging. The calculated load is less than the rated lifting capacity, which is safe.
