[0001] The present invention relates to the technical field of construction lifting platforms, and specifically relates to an intelligent construction integrated construction platform and a construction method thereof. Background Art

[0002] In the construction of medium and high-rise buildings, in order to accelerate the deep integration of the construction industry with advanced manufacturing technologies and realize a new generation of information technologies, most existing construction platforms involve lifting operations on the platform through a controller to facilitate the transportation of materials and the adjustment of the construction height. However, most of the liftable construction platforms are installed with cranes, steel wire winches, etc. on top after the scaffolding is completed to lift and lower the platform. This structure and the lifting and hoisting method do not have good stability in use. Especially when equipment such as cranes and steel wire winches fails, it is impossible to hold the lifting platform, and it is very easy for the lifting platform to crash, resulting in a series of casualties and losses. The overall safety protection needs to be improved. Therefore, it is necessary to propose an intelligent construction integrated construction platform and a construction method thereof. Summary of the Invention

Guide wheels are installed on both sides at the bottom of the rectangular vertical frame. A lifting platform is lifted and lowered in the middle of the rectangular vertical frame. Rectangular frames are fixedly arranged on the left and right sides of the lifting platform, and the rectangular frames are respectively slidably sleeved on the vertical rods on the left and right sides of the rectangular vertical frame. A controller for controlling the execution of each electrical component is installed in the middle of the lifting platform, and speed detectors are installed on the left and right sides of the lifting platform. A winding crane installed on the foundation and located on the left and right sides of the rectangular vertical frame. The winding crane uses a steel wire sling to pass through the guide wheel and the lifting wheel in sequence, and the lifting platform is vertically suspended downward by the rectangular vertical frame. Vertical toothed plates are fixedly arranged on the left and right sides of the rectangular vertical frame. Elastic deceleration components are arranged on the left and right sides of the lifting platform for elastically expanding and tightening on the tooth openings on the opposite sides of the two toothed plates. The two steel wire slings are respectively located between the elastic deceleration component and the toothed plate. When the elastic deceleration component is tensioned on the two toothed plates, the steel wire sling is synchronously tightened on the toothed plate for tightening and decelerating. A plurality of bidirectional telescopic clamping members are respectively installed horizontally on the upper and lower sides of the lifting platform, and the lifting platform is clamped on the tooth openings on the opposite sides of the toothed plate through the bidirectional telescopic clamping members for tightly clamping and fixing the lifting platform on the toothed plate. A bottom platform is fixedly arranged at the bottom of the lifting platform, and a multi-stage elastic support group and a reverse downward pushing component are arranged at the bottom of the bottom platform for multi-stage buffering support when the lifting platform falls.

[0005] Preferably, the toothed plate includes a plate body, and a plurality of triangular convex tooth racks are arranged upright on one side of the plate body, and an inclined groove surface inclined downward is provided on the upper side of each triangular convex tooth rack.

[0006] Preferably, a hydraulic cylinder is vertically installed in the middle of the bottom platform. The hydraulic cylinder is located below the multi-stage elastic support group, and a hydraulic piston rod is installed on the lower side piston of the hydraulic cylinder. The bottom end of the hydraulic piston rod is connected to the multi-stage elastic support group. A plurality of oil distribution pipes are annularly arranged on the outer side of the top of the hydraulic cylinder, and the end of each oil distribution pipe is connected to the reverse downward pushing assembly.

[0007] Preferably, the multi-stage elastic support group includes a locking frame plate locked at the bottom of the bottom platform. A third support plate, a second support plate and a first support plate are sequentially movably arranged from the outside to the inside in the middle of the locking frame plate.

The second support plate is vertically movably embedded in the middle of the third support plate. The third support plate is vertically movably embedded in the middle of the locking frame plate, and the third support plate, the second support plate and the first support plate are distributed in a stepped shape, forming different contact height differences; A plurality of short springs are installed on the upper side of the third support plate and are elastically supported and connected to the bottom of the bottom platform. A plurality of medium springs are installed on the upper side of the second support plate and are elastically supported and connected to the bottom of the bottom platform. A plurality of long springs are installed on the upper side of the first support plate and are elastically supported and connected to the bottom of the bottom platform; The upper side of the first support plate is connected to the bottom of the hydraulic piston rod.

[0008] Preferably, the reverse downward pushing assembly includes a rubber air cushion movably embedded in the lower side of the locking frame plate and a column cylinder body fixedly installed on the inner side of the locking frame plate. A piston push rod is arranged on the inner side piston of the column cylinder body, and a connecting ring plate is installed at the bottom end of each piston push rod. The rubber air cushion is fixedly arranged at the bottom of the connecting ring plate. The top of each column cylinder body is correspondingly connected to each oil distribution pipe. When the lifting platform falls, the first support plate is preferentially elastically buffered and stressed. When the first support plate moves upward, it can also drive the hydraulic piston rod to upwardly extrude the hydraulic oil of the hydraulic cylinder into each oil distribution pipe, and push the piston push rods of each column cylinder body to move downward, synchronously making the rubber air cushion at the bottom of the connecting ring plate move downward and generate a downward thrust for double support.

[0009] Preferably, the elastic deceleration assembly includes an air pump installed on the top of the lifting platform. An air distribution pipe is installed at the air outlet end of the air pump. The two ends of the air distribution pipe are respectively connected to a mounting plate. The two mounting plates are installed on the left and right sides of the lifting platform, and a rubber air charging bag is arranged in the middle of the outer side of the mounting plate and corresponds to one side of the toothed plate. The steel wire sling is located between the toothed plate and the rubber air charging bag.

[0010] Preferably, the outer surface of the rubber inflatable bag is integrally provided with a plurality of vertically arranged transverse convex strips, and the transverse convex strips abut against the teeth of the tooth plate.

[0011] Preferably, the bidirectional telescopic clamping member comprises a bidirectional telescopic rod, and a clamping plate is fixed to each of the two telescopic ends of the bidirectional telescopic rod. The outer end of the clamping plate is adapted to be clamped on the inclined groove surface on the upper side of the triangular convex rack, and the outer end of the clamping plate is arc-shaped.

[0012] Preferably, the front and rear sides of the rectangular frame are respectively locked with front and rear upright plates, and guide grooves are vertically opened on the front, rear, left and right outer surfaces of the rectangular frame. Sliding rollers are installed on the rectangular frame and the front and rear upright plates. When the rectangular frame is mounted on the upright poles on the left and right sides of the rectangular frame, the rectangular frame and the front and rear upright plates are rollingly connected with the guide grooves through the sliding rollers.

[0013] A construction method for an intelligent integrated construction platform, wherein a controller is used to control two winding cranes to synchronously wind up the wire rope, so that the wire rope passes through the guide wheel at the bottom of the rectangular frame and the lifting wheel at the top to simultaneously lift the lifting platform, and the rectangular frames on both sides of the lifting platform slide upward along the rectangular frame to guide the entire lifting platform to reach a specified construction height, and the lifting platform can be tightened and clamped on the rectangular frame by a two-way telescopic clamping piece extending in both directions and clamping on the teeth on the opposite sides of the tooth plates on both sides of the rectangular frame, so as to facilitate construction operations; during the lifting of the lifting platform, the winding crane In the event of failure or damage, the lifting platform loses its pulling force and falls downward. The speed detector detects that the speed of the lifting platform is too fast and then feeds back to the controller, which controls the elastic deceleration component to elastically expand and tighten on the teeth on the opposite side of the two tooth plates, so that the lifting platform slowly descends until it stops descending, and the lifting platform is stabilized under the extension and clamping of the two-way telescopic clamping parts. In addition, when the lifting platform completely falls and touches the bottom, it is progressively buffered by the multi-stage elastic support group. The buffer support of the multi-stage elastic support group simultaneously links the reverse push-down component to move downward to generate a pushing force for secondary buffering support, thereby reducing the impact force of the lifting platform landing.

[0014] By adopting the above technical solution, the present invention has the following advantages compared with the existing technology: On both sides of the lifting platform of the present invention, a rectangular frame is used for sliding up and down and is located in the middle of the rectangular vertical frame, forming an integral body with the rectangular vertical frame to improve the overall structural stability. Moreover, the winding crane of the present invention is not installed on the top of the rectangular vertical frame. Instead, two winding cranes are installed on the foundation and the steel wire hoisting ropes are led to the top of the rectangular frame through guide wheels and lifting wheels for hoisting the lifting platform. This setting has multiple advantages: for example, the winding crane is installed on the foundation, and its own weight and traction force are directly transmitted to the ground foundation, avoiding the problem of too high center of gravity caused by placing heavy power on the top of the vertical frame, and lowering the overall center of gravity of the equipment, greatly reducing the risk of overturning caused by the movement of the load of the lifting platform or external wind force; moreover, compared with the traditional winding crane installed on the top, which requires the vertical frame to bear all the hoisting torque, it is less likely to cause deformation of the vertical frame, and maintenance or replacement of components can be carried out without working at height, greatly reducing the maintenance difficulty and time; another important advantage is that the steel wire hoisting rope is located between the toothed plate and the elastic deceleration component. When the falling speed of the lifting platform is detected to be too fast, it can expand under the rapid inflation of the rubber inflation balloon of the elastic deceleration component, and the transverse ridges are tightened on the tooth openings of the two toothed plates, increasing the elastic frictional force during falling until the lifting platform stops slowly. Then, in cooperation with the extension of the bidirectional telescopic clamping member to abut against the toothed plate for temporarily fixing the lifting platform, and when the rubber inflation balloon and the transverse ridges expand, the steel wire hoisting rope can also be tightened on the toothed plate synchronously, further improving the frictional force to achieve the fastening effect, greatly reducing the anti-falling effect of the lifting platform; Meanwhile, a bottom platform is installed at the bottom of the lifting platform. A multi-stage elastic support group and a reverse downward pushing component are arranged at the bottom of the bottom platform. When the lifting platform directly falls and touches the ground, the third support plate, the second support plate and the first support plate of the multi-stage elastic support group distributed in a stepped shape can be correspondingly extended and buffered according to the impact force during falling, forming a step-by-step energy absorption path and avoiding stress concentration caused by simultaneous force application, significantly improving the buffering efficiency; and when the first support plate retracts upward under the impact, it can also drive the hydraulic piston rod to squeeze the hydraulic oil of the hydraulic cylinder into each branch oil pipe, so that the oil pressure in the branch oil pipe pushes the piston push rod, the connecting ring plate and the rubber air cushion of the reverse downward pushing component to displace downward, forming a pushing force to further support and disperse the impact energy with the foundation, realizing double support for the falling of the lifting platform and improving the overall use effect.

Detailed implementation manners

[0016] To make the technical means, creative features, achieving purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with the detailed implementation manners.

[0017] As Figure 1-12As shown in the figure, the present invention provides an intelligent integrated construction platform, which includes a rectangular vertical frame 2 embedded in the foundation. A connecting top plate 21 and a lifting pulley 22 are installed at the top of the rectangular vertical frame 2. Guide wheels 23 are installed on both sides of the bottom of the rectangular vertical frame 2. A lifting platform 1 located in the middle of the rectangular vertical frame 2 is lifted. Rectangular frames 5 are fixedly provided on the left and right sides of the lifting platform 1, and the rectangular frames 5 are respectively slidably sleeved on the vertical rods on the left and right sides of the rectangular vertical frame 2. A controller 10 for controlling the execution of various electrical accessories is installed in the middle of the lifting platform 1, and speed detectors 11 are installed on the left and right sides of the lifting platform 1. A winding hoist 4 installed on the foundation and located on the left and right sides of the rectangular vertical frame 2. The winding hoist 4 uses a steel wire sling 41 to pass through the guide wheel 23 and the lifting pulley 22 in sequence, and vertically suspends the lifting platform 1 downward by the rectangular vertical frame 2. Since the winding hoist 4 is installed on the foundation, its own weight and traction force are directly transmitted to the ground foundation, avoiding the problem of too high center of gravity caused by placing heavy power on the top of the vertical frame, and lowering the overall center of gravity of the equipment, greatly reducing the risk of overturning caused by the load movement of the lifting platform 1 or external wind force; moreover, compared with the traditional winding hoist installed on the top, the vertical frame 2 needs to bear all the lifting moments, making it less likely for the vertical frame to deform, and there is no need for high-altitude operation to perform maintenance or replace components, greatly reducing the maintenance difficulty and time; and in order to enable the lifting platform 1 to slide up and down smoothly and stably on the rectangular vertical frame 2, front and rear vertical plates 51 are respectively locked on the front and rear sides of the rectangular frame 5. Guide grooves 24 are respectively vertically opened on the front, rear, left and right outer surfaces of the rectangular vertical frame 2. Sliding rollers 52 are installed on both the rectangular frame 5 and the front and rear vertical plates 51. When the rectangular frame 5 is sleeved on the vertical rods on the left and right sides of the rectangular vertical frame 2, the rectangular frame 5 and the front and rear vertical plates 51 are both in guiding rolling connection with the guide grooves 24 through the sliding rollers 52, playing a role of guiding and reducing friction.

[0018] Among them, vertical toothed plates 3 are fixedly arranged on the left and right sides of the rectangular vertical frame 2. Elastic deceleration components 7 are arranged on the left and right sides of the lifting platform 1 and are used to elastically expand and tighten on the tooth openings on the opposite sides of the two toothed plates 3. Two steel wire suspension ropes 41 are respectively located between the elastic deceleration components 7 and the toothed plates 3. When the elastic deceleration components 7 are tensioned on the two toothed plates 3, the steel wire suspension ropes 41 are synchronously pressed against the toothed plates 3 for pressing and decelerating. The elastic deceleration components 7 include an air pump 71 installed on the top of the lifting platform 1. An air distribution pipe 72 is installed at the air outlet end of the air pump 71. Both ends of the air distribution pipe 72 are respectively connected with mounting plates 73. The two mounting plates 73 are installed on the left and right sides of the lifting platform 1. And a rubber inflation balloon 74 is arranged in the middle of the outer side of the mounting plate 73 and corresponds to one side of the toothed plate 3. The steel wire suspension rope 41 is located between the toothed plate 3 and the rubber inflation balloon 74. In this way, the air pump 71 inflates the rubber inflation balloons 74 on both sides through the air distribution pipe 72 respectively, making them expand. In this way, the rubber inflation balloons 74 can directly expand and tighten between the two toothed plates 3 to increase the friction force and pressing force, which is used for the deceleration and pressing of the lifting platform 1 when it falls. And a plurality of horizontally convex strips 75 arranged vertically in a row are integrally arranged on the outer surface of the rubber inflation balloon 74, and the horizontally convex strips 75 are abutted against the tooth openings of the toothed plate 3. In this way, the friction force between them can be greatly increased, so as to effectively reduce the falling speed until the falling stops. Moreover, in order to enable the horizontally convex strips 75 to have a certain slipping effect downward and avoid the excessive contact wear of the horizontally convex strips 75 due to the too rigid contact with the tooth openings, the structure of the toothed plate 3 is designed as a plate body 31. A plurality of triangular convex tooth strips 32 are integrally arranged upward on one side of the plate body 31. And a slightly inclined downward inclined groove surface 33 is arranged on the upper side of each triangular convex tooth strip 32. In this way, when the rubber inflation balloon 74 expands and presses against the triangular convex tooth strips 32, the horizontally convex strips 75 can be clamped on the inclined downward inclined groove surface 33. In this way, the horizontally convex strips 75 are less likely to be worn during friction.

[0019] Furthermore, two groups of bidirectional telescopic clamping members 6 are horizontally installed on the upper and lower sides of the lifting platform 1 respectively, and the lifting platform 1 is clamped on the tooth openings on the opposite sides of the toothed plate 3 through the bidirectional telescopic clamping members 6, which is used to press and clamp the lifting platform 1 on the toothed plate 3. The bidirectional telescopic clamping members 6 include bidirectional telescopic rods 61. The bidirectional telescopic rods 61 are bidirectional electric push rods or bidirectional electric cylinders in the prior art. Clamping plates 62 are fixedly arranged at the two telescopic ends of the bidirectional telescopic rods 61 respectively. The outer ends of the clamping plates 62 can be adaptively clamped on the inclined groove surface 33 on the upper side of the triangular convex tooth strips 32, which is used to stabilize the lifting platform 1 on the toothed plate 3. And the outer ends of the clamping plates 62 are arc-shaped. In this way, it is easier to slide down to the adjacent inclined groove surface 33 for support when pressing against the sharp corners of the triangular convex tooth strips 32.

[0020] Furthermore, a bottom platform 8 is fixedly installed at the bottom of the lifting platform 1, and a multi-stage elastic support group 9 and a downward pushing component 95 are arranged at the bottom of the bottom platform 8 for multi-stage buffer support when the lifting platform 1 falls. Specifically, the multi-stage elastic support group 9 includes a locking frame plate 91 locked at the bottom of the bottom platform 8. A third support plate 92, a second support plate 93, and a first support plate 94 are sequentially and movably arranged from outside to inside in the middle of the locking frame plate 91. The first support plate 94 is vertically movably embedded in the middle of the second support plate 93 and is located at the bottommost end. The second support plate 93 is vertically movably embedded in the middle of the third support plate 92. The third support plate 92 is vertically movably embedded in the middle of the locking frame plate 91. The third support plate 92, the second support plate 93, and the first support plate 94 are distributed in a stepped manner to form different contact height differences. A plurality of short springs 921 are installed on the upper side of the third support plate 92 and are elastically supported and connected to the bottom of the bottom platform 8. A plurality of medium springs 931 are installed on the upper side of the second support plate 93 and are elastically supported and connected to the bottom of the bottom platform 8. A plurality of long springs 941 are installed on the upper side of the first support plate 94 and are elastically supported and connected to the bottom of the bottom platform 8. Therefore, the first support plate 94 forms a first-stage buffer under the action of the long springs 941, the second support plate 93 forms a second-stage buffer under the action of the medium springs 931, and the third support plate 92 forms a third-stage buffer under the action of the short springs 921, extending the buffer. The single-point bearing is gradually converted into multi-stage dispersion to form a step-by-step energy absorption path, and at the same time, stress concentration caused by simultaneous force application is avoided, significantly improving the buffer efficiency.

[0021] Furthermore, a hydraulic cylinder 81 is vertically installed in the middle of the bottom platform 8. The hydraulic cylinder 81 is located below the multi-stage elastic support group 9, and a hydraulic piston rod 811 is installed on the lower side piston of the hydraulic cylinder 81. The bottom end of the hydraulic piston rod 811 is connected to the first support plate 94 of the multi-stage elastic support group 9. Ten sub-oil pipes 82 are annularly arranged on the outer side of the top of the hydraulic cylinder 81, and the ends of the respective sub-oil pipes 82 are connected to the downward pushing component 95. In this way, when the first support plate 94 is impacted and retracts upward, it can push the hydraulic piston rod 811 to displace upward, pump the hydraulic oil inside the hydraulic cylinder 81 into the ten sub-oil pipes 82, and transmit the pressure to the downward pushing component 95, so that the downward pushing component 95 has a downward pushing force to offset part of the impact force of the fall; specifically, the downward pushing component 95 includes a rubber air cushion 950 movably embedded in the lower side of the locking frame plate 91 and a columnar cylinder body 951 fixedly installed on the inner side of the locking frame plate 91. A piston push rod 952 is arranged on the inner side piston of the columnar cylinder body 951, and a connecting ring plate 953 is installed at the bottom end of each piston push rod 952. The rubber air cushion 950 is fixedly arranged at the bottom of the connecting ring plate 953. The tops of the respective columnar cylinder bodies 951 are correspondingly connected to the respective sub-oil pipes 82. When the lifting platform 1 falls, the first support plate 94 preferentially bears the force by elastic buffering. The upward displacement of the first support plate 94 can also drive the hydraulic piston rod 811 to squeeze the hydraulic oil of the hydraulic cylinder 81 into the respective sub-oil pipes 82, and push the respective piston push rods 952 of the columnar cylinder body 951 to displace downward, synchronously causing the rubber air cushion 950 at the bottom of the connecting ring plate 953 to displace downward, thereby generating a downward pushing force to elastically contact the ground, and further supporting and dispersing the impact energy through the pushing force and the foundation.

[0022] For a more specific usage method, the controller 10 controls the two rewinding cranes 4 to rewind the steel wire sling 41 synchronously, allowing the steel wire sling 41 to pass through the guide wheel 23 at the bottom of the rectangular vertical frame 2 and the lifting wheel 22 at the top to lift and pull the lifting platform 1 simultaneously. At this time, the steel wire sling 41 is located between the rubber air bag 74 and the toothed plate 3. During the lifting and pulling, the rectangular frames 5 on both sides of the lifting platform 1 roll and slide upward through the sliding rollers 52 in the guide grooves 24 of the rectangular vertical frame 2 until the entire lifting platform 1 reaches the specified construction height. After reaching the height, the double telescopic clamping member 6 extends the double telescopic rod 61 to both left and right sides simultaneously, so that the clamping plate 62 at its telescopic end can be clamped on the tooth openings on the opposite sides of the two toothed plates 3, that is, clamped on the inclined groove surface 33 on the upper side of the triangular convex tooth rack 32, thereby improving the stability of the lifting platform 1 for construction operations; and during the lifting and lowering of the lifting platform 1, when the steel rope breaks, the rewinding crane 4 fails or is damaged and loses its pulling force, the lifting platform 1 falls downward. After the speed detector 11 detects that the speed of the lifting platform 1 is too fast, it feeds back to the controller 10, and the controller 10 controls the air pump 71 of the elastic deceleration component 7 to quickly inflate the rubber air bag 74 of the mounting plate 73, causing the rubber air bag 74 to expand outward and press tightly between the two toothed plates 3, and using the transverse convex strip 75 to flexibly clamp and press tightly on the inclined groove surface 33 on the upper side of the triangular convex tooth rack 32 of the toothed plate 3. Since the rubber air bag 74 has an elastic contraction effect, when the weight of the lifting platform 1 is large, the inflation speed of the rubber air bag 74 is slow. Therefore, the initial inflation force of the rubber air bag 74 is not enough to stably press the transverse convex strip 75 against the two toothed plates 3, and the lifting platform 1 will still slide downward. At this time, the rubber air bag 74 uses the friction between the transverse convex strip 75 and the toothed plate 3 to play a decelerating role, which can reduce the falling speed of the lifting platform 1 until the inflation force of the rubber air bag 74 is sufficient to tension the lifting platform 1 on the toothed plate 3, achieving the effect of the lifting platform 1 slowly descending until it stops descending. And because the steel wire sling 41 is designed between the rubber air bag 74 and the toothed plate 3, the rubber air bag 74 can also increase the friction force of the steel wire sling 41 when it expands, realizing the fastening of the steel wire sling 41 and further enhancing the effect of the slow downward fall of the lifting platform 1. When the lifting platform 1 stops descending or the descending speed reaches a relatively stable speed, the double telescopic rod 61 of the double telescopic clamping member 6 extends to make the clamping plate 62 rigidly clamped on the tooth openings of the two toothed plates 3 to stabilize the lifting platform 1; Moreover, when the lifting platform 1 slowly descends and touches the bottom under the action of the elastic deceleration component 7, the multi-stage elastic support group 9 installed at the bottom of the bottom platform 8 can further elastically buffer. Due to the third support plate 92, the second support plate 93, and the first support plate 94 of the multi-stage elastic support group 9 being distributed in a stepped manner, it can extend and buffer in corresponding levels according to the impact force during the fall, forming a step-by-step energy absorption path and avoiding stress concentration caused by simultaneous force application. For example, when the bottommost first support plate 94 touches the bottom, it retracts upward, using the long spring 941 for preliminary elastic buffering. When the downward impact force is too large, the second support plate 93 and the third support plate 92 will be gradually retracted upward, using the medium spring 931 and the short spring 921 for secondary and tertiary elastic progressive buffering to disperse the impact force, significantly improving the buffering efficiency. When the first support plate 94 is impacted and retracts upward, it can also push the hydraulic piston rod 811 upward to squeeze the hydraulic oil in the hydraulic cylinder 81 into each sub-oil pipe 82. The hydraulic oil in the sub-oil pipe 82 enters the column cylinder 951 of each downward pushing component 95, and pushes the piston push rod 952, the connecting ring plate 953, and the rubber air cushion 950 to displace downward in the reverse direction to form a pushing force. Through this pushing force and the foundation, the impact energy is further supported and dispersed. At the same time, the tightening effect of the rubber air bag 74 and the transverse convex strip 75 of the elastic deceleration component 7 with the toothed plate 3 is also beneficial to eliminating the risk of rebound and improving the overall use effect.

[0023] It should be noted that for an intelligent construction integrated construction platform of the present invention, the above structure is mainly improved.

Without departing from the principle of the present invention, those skilled in the art can also make many deformations and improvements, which should also be regarded as the protection scope of the present invention.
