Description

Technical Field

[0001] The utility model belongs to the technical field of construction machinery and equipment, and in particular relates to a lifting work platform for people and components integrated with each other, which is suitable for a cantilever structure. Background Art

[0002] At present, prefabricated construction is being vigorously promoted due to its distinct and unique advantages. A great feature of prefabricated construction is the on-site assembly of prefabricated components, such as truss lap joints and loose parts assembly, which are necessary work contents on site. For some cantilever structures, the current common hoisting method is to use large cranes or tower cranes for hoisting, which has the following disadvantages:

[0003] 1) The lifting operation only solves the lifting of components. Workers who need welding work need to go to the joints through other channels to perform welding work. The construction environment that usually requires lifting is high-altitude work, and the only protective device is a safety rope, which has poor safety and is inconvenient for subsequent welding quality inspection.

[0004] 2) The lifting operation process is relatively complicated, and the lifting parking space and lifting points need to be determined first.

[0005] 3) The working space required for lifting is large, which can easily affect other construction operations.

[0006] 4) The lifting operation is unstable and easily affected by the external environment, and the alignment of components and welding points is difficult to control. Utility Model Content

[0007] In view of the shortcomings of the prior art, the technical problem to be solved by the utility model is: it solves the problem that conventional lifting platforms can only perform vertical lifting. Compared with conventional crane lifting, the utility model has advantages in the splicing work of medium and low-rise cantilevered building structures. It avoids the risks of high-altitude operations for welding workers, saves operation time and costs, and greatly improves work efficiency.

[0031] The present invention will be further explained below in conjunction with specific embodiments. The embodiments are implemented based on the technical solution of the present invention. It should be understood that these embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention.

[0032] like Figure 1-6As shown, the utility model is a person-member integrated lifting work platform suitable for cantilever structures, comprising an operating platform 12, a scissor-type hydraulic lifting mechanism, a rotation displacement mechanism and a moving device arranged in sequence from top to bottom.

[0033] like Figure 1 , 6 As shown, a movable clamping member 2 and a slide groove 11 are provided on the upper surface of the operating platform 12. The number of movable clamping members 2 and slide grooves 11 is multiple. The movable clamping member 2 is U-shaped, arranged on the slide groove 11, and is slidably connected to the slide groove 11. A hole is opened on the movable clamping member 2. A telescopic propulsion rod 22 and a hydraulic cylinder 23 are provided on the movable clamping member 2. The hydraulic cylinder 23 is arranged on the telescopic propulsion rod 22, and the hydraulic cylinder 23 is fixedly connected to one end of the slide groove 11.

[0034] In this embodiment, the number of the slide grooves 11 is two, and there are two movable clamping members 2 on a single slide groove 11 .

[0035] A fence 3 is arranged around the side of the operating platform 12, and the fence 3 plays a role of protecting the workers during the lifting and working process.

[0036] An alarm light 1 and a sensor 15 are provided on the operating platform 12. The sensor 15 is used to collect height and load data. When the device arrives at the working area, the prefabricated components are placed on the operating platform 12 by means of a small crane, forklift or other means. The weight of the prefabricated components and the staff on the operating platform 12 is monitored by the sensors on the operating platform 12. When overweight or center of gravity deviation occurs, the sensor will send information to the control end and the alarm will sound. The model of the sensor for measuring the center of gravity deviation selected in this embodiment is the U2A / 1t German HBM weighing sensor.

[0037] When the prefabricated components are placed, the four movable clamping members 2 are moved on the slide 11 to clamp the prefabricated components through the hydraulic cylinder 23 and the telescopic propulsion rod 22, and finally the prefabricated components and the operating platform 12 are fixed again by using steel wire ropes passing through the holes on the clamping members.

[0038] like Figure 1 , 2 As shown, the scissor-type hydraulic lifting mechanism includes a folding bracket, a gas-liquid booster cylinder 13, a support 18, a high-strength bolt 19, and a support rod 20.

[0039] The support 18 is square, and a plurality of through holes are correspondingly provided on the support 18 and the supporting chassis 7, and high-strength bolts 19 pass through the through holes to fix the support 18 to the supporting chassis 7; the folding bracket is arranged in the support 18, and a wheel rail 17 is arranged on the inner side of the support 18, and there are two wheel rails 17, and a sliding wheel 16 is slidably connected to the wheel rail 17, and a support rod 20 is arranged on the folding bracket, and the gas-liquid booster cylinder 13 is arranged on the support rod 20. The support 18 is welded by 2 angle steels and 2 square steels. The wheel rail 17 is magnetic, so that the sliding wheel 16 keeps in contact with the wheel rail without vertical deviation. When the hydraulic system lifts the operating platform 12 to a predetermined height, the sliding wheel 16 does not move due to the restriction of the gas-liquid booster cylinder 13.

[0040] The folding bracket includes a connecting shaft 4, a passive support arm 5 and an active support arm 6; the number of the connecting shaft 4, the passive support arm 5 and the active support arm 6 are all multiple; the connecting shaft 4 is arranged between the passive support arms 5, and one end of the passive support arm 5 is fixedly connected to the sliding wheel 16; one end of the active support arm 6 is fixedly connected to the inner side of the support 18, and the active support arm 6 is inserted into the passive support arm 5.

[0041] A plurality of active support arms 6 and passive support arms 5 are cross-formed into a planar telescopic structure, and a transverse connecting shaft 4 is connected between the two telescopic surface structures. The lower end of the passive support arm 5 and the middle of the active support arm 6 are rigidly connected by transverse support rods 20, and the gas-liquid booster cylinder 13 is connected between the two support rods 20.

[0042] Start the gas-liquid booster cylinder 13, and the hydraulic rod in the gas-liquid booster cylinder 13 pushes the support rod 20 to move, thereby driving the pulley in the support 18 to roll on the wheel rail 17. At the same time, one end of the active support arm 6 is connected to the support 18 in a hinged form, thereby driving the rotation of the passive support arm 5. All gas-liquid booster cylinders 13 work at the same time, and the shaft 4 between the upper and lower support rods 20 is driven to realize the rotation transmission and overall lifting of the active support arm 6. When the overall prefabricated component is lifted to the corresponding height, the sensor 15 sends a signal to the control end, so that the hydraulic lifting mechanism stops working.

[0043] In this embodiment, there are 4 scissor-type hydraulic lifting mechanisms, 12 gas-liquid booster cylinders 13, 48 active support arms 6 and 48 passive support arms 5, 12 through holes are provided on the support chassis 7 and the support 18, and two wheel rails 17 and two sliding wheels 16 are provided in a single support 18.

[0044] like Figure 3As shown, a connector 21 is provided at the bottom end of the operating platform 12, and the number of the connectors 21 is 24. The connectors 21 are fixedly connected to the folding bracket. The middle bearing of the connector 21 can rotate on the vertical plane and achieve vertical displacement along with the support rod 20 in the scissor-type hydraulic lifting mechanism. The outer ring of the connector 21 is fixedly connected to the operating plane.

[0045] like Figure 1 , 4 As shown in Figures 5 and 6, the rotary displacement mechanism includes a cast iron platform 8, a central rotating shaft 9, a supporting chassis 7 and a guide groove 14; the guide groove 14 is embedded in the middle of the cast iron platform 8, and a gear 24 and a rotating shaft 25 are provided on both sides of the guide groove 14, and the rotating shaft 25 is embedded in the center of the gear 24; a protruding rack 26 is provided in the middle of the bottom of the supporting chassis 7, the rack 26 is placed in the guide groove 14, and the rack 26 is meshed with the gear 24.

[0046] The central rotating shaft 9 is arranged below the cast iron platform 8. The central rotating shaft 9 includes an outer gear 28 and an inner gear 29. The outer gear 28 is arranged on the outer periphery of the inner gear 29. The outer gear 28 and the inner gear 29 are meshed with each other. A rotating joint 27 is fixedly connected to the inner gear 29. The top end of the rotating joint 27 is fixedly connected to the bottom of the cast iron platform 8. A support frame 30 is provided at the lower end of the central rotating shaft.

[0047] The electric motor is placed in the cast iron platform 8. The electric motor controls the rotation of the rotating shaft 25, which then drives the gear 24 to rotate. Finally, through the mechanical engagement with the rack 26, the sliding displacement of the supporting chassis 7 is achieved, thereby achieving horizontal displacement of the superstructure. At the same time, the length of the moving guide groove 14 is controlled within a safe range, limiting a certain displacement to prevent excessive lateral displacement, which may lead to overturning problems caused by center of gravity shift.

[0048] Start the rotary motor installed on the support frame 30 to drive the central rotary shaft 9, and drive the rotary joint 27 and the cast iron platform 8 to rotate as a whole, support the chassis 7 to slide horizontally with the cast iron platform 8 in the guide groove 14, and perform more precise correction and alignment. After the alignment is completed, the welding worker performs welding operations on the operating platform 12 and checks the weld quality after welding.

[0049] In this embodiment, the number of the rack 26 , the gear 24 , and the rotating shaft 25 is two.

[0050] like Figure 1 As shown, the mobile device includes a traveling track 10, a guide wheel, a driven wheel, a supporting wheel and a traveling motor, and the left and right tracks are connected by a support frame 30. The traveling track 10 contacts the ground and is responsible for moving the vehicle to the working area. The traveling track 10 is connected to the central rotating shaft 9 through the support frame 30.

[0051] The working principle or use process of the utility model is as follows: when the lifting work platform reaches the working area, the pre-assembled components are placed on the operating platform 12 by means of a small crane, forklift or the like, and the weight and height of the prefabricated components and the staff on the operating platform 12 are monitored by the sensor 15 on the operating platform 12. When overweight or the center of gravity is misaligned, the alarm sounds; when the prefabricated components are placed, the four movable clamping parts 2 are moved on the slide 11 through the action of the hydraulic cylinder 23 and the telescopic propulsion rod 22 to clamp the prefabricated components, and the prefabricated components and the operating platform 12 are fixed again by passing the steel wire rope through the holes on the clamping parts.

[0052] Then, the gas-liquid booster cylinder 13 is started, and the hydraulic rod in the gas-liquid booster cylinder 13 pushes the support rod 20 to move, thereby driving the pulley in the support 18 to roll on the wheel rail 17. At the same time, one end of the active support arm 6 is connected to the support 18 in a hinged form, thereby driving the rotation of the passive support arm 5. All gas-liquid booster cylinders 13 work at the same time, and the shaft 4 between the upper and lower support rods 20 is driven to realize the rotation transmission and overall lifting of the active support arm 6. When the overall prefabricated component is lifted to the corresponding height, the sensor 15 sends a signal to the control end, so that the hydraulic lifting mechanism stops working.

[0053] During the work, the staff starts the four electric motors installed in the cast iron platform 8, and drives the rotating shaft 25, gear 24, and rack 26 in turn to achieve the sliding displacement of the supporting chassis 7, and then achieve the horizontal displacement of the upper structure. The staff starts the rotary motor installed in the support frame 30, and drives the outer gear 28, the inner gear 29 and the rotary joint 27 to rotate in turn, so that the cast iron platform 8 rotates as a whole, and the supporting chassis 7 moves horizontally with the cast iron platform 8 in the guide groove 14, so as to make more accurate correction and alignment. After the alignment is completed, the welding workers perform welding operations on the operating platform 12, and check the quality of the weld after welding.

[0054] The above is only a preferred embodiment of the present invention. It should be pointed out that ordinary technicians in this technical field can make several improvements and modifications without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
