Abstract

The present invention provides a method for using a climbing formwork cylinder frame that can enhance safety performance. By arranging a co-lifting inductor at the hanging hole of each lifting lug at the top of the four corners of the cylinder frame body, co-lifting lock catches are respectively arranged at positions near the corners at the top of the cylinder frame body. Grooves for the corresponding co-lifting lock catches to extend into are arranged at intervals along the longitudinal direction on the guide rail. When all the co-lifting inductors detect that the corresponding lifting ropes are located in the corresponding hanging holes, the staff inside the cylinder frame body notify the controller to unlock the co-lifting lock catches through operating the display screen. After all the co-lifting lock catches are unlocked, the tower crane construction personnel can start to lift the climbing formwork cylinder frame, thereby ensuring that all four lifting lugs are stressed during the lifting process of the climbing formwork cylinder frame, effectively avoiding safety accidents caused by the "double-point - diagonal" lifting method in the on-site construction process, and improving the safety of the climbing formwork cylinder frame.

Description

Technical Field

[0001] The present invention belongs to the technical field of building construction, and particularly relates to a method for using a climbing formwork cylinder frame that can improve safety performance. Background Art

[0002] With the continuous increase of building heights in China, a climbing formwork system has been introduced during the construction process. Workers carry out construction through the climbing formwork cylinder frame during the construction process. However, there are frequently safety problems with the climbing formwork cylinder frame during the construction process. For example, for the four lifting lugs at the top of the climbing formwork cylinder frame, when only two diagonal lugs are stressed, during the lifting process of the climbing formwork cylinder frame, once one side of the climbing formwork cylinder frame is blocked, it will cause the climbing formwork cylinder frame to tip over, resulting in safety accidents.

[0003] The above safety problems occur for two reasons. Firstly, traditional equipment has a simple device and unreasonable design, with potential safety hazards. Secondly, there is a problem of weak safety awareness among workers, with illegal operations. The operation process depends entirely on the workers' feelings. Various reasons like this have hidden safety hazards. Summary of the Invention

[0004] The present invention aims to provide a method for using a climbing formwork cylinder frame that can improve safety performance, and solve the problem of low safety during the lifting process of the climbing formwork cylinder frame in the prior art.

[0005] To solve the above technical problems, the present invention provides the following technical solutions:

[0006] A method for using a climbing formwork cylinder frame that can improve safety performance, the climbing formwork cylinder frame includes a cylinder frame body, a plurality of lifting lugs, a plurality of lifting sensors, a plurality of lifting locks, an operation display screen, and an alarm device. The cylinder frame body is a rectangular box structure with a closed bottom and an open top. At the top of each of the four corners of the cylinder frame body, a lifting lug is provided. The lifting lug has a lifting hole for a lifting rope to pass through. A lifting sensor is arranged in each lifting hole. The cylinder frame body can move up and down relative to the climbing formwork under the lifting of a tower crane. There are four vertically arranged columns around the cylinder frame body. Guide rails matching the corresponding columns are provided on the climbing formwork. The operation display screen is arranged inside the cylinder frame body. The lifting sensors, lifting locks, operation display screen, and alarm device are respectively connected to a controller. The lifting sensor can detect whether the lifting rope is located in the corresponding lifting hole and send the detected information to the controller. The lifting locks are respectively arranged at positions near the corners at the top of the cylinder frame body. Grooves for the corresponding lifting locks to extend into are arranged at intervals along the longitudinal direction on the guide rails. The lifting locks have two states of locking and unlocking under the action of the controller. When the lifting locks are locked, the lifting locks respectively extend into the corresponding grooves. When the lifting locks are unlocked, the lifting locks respectively leave the corresponding grooves. The method includes the following steps:

[0007] The on-site commander sends a signal to the hoisting driver. The hoisting driver makes preparations for hoisting, threading the hoisting ropes of the tower crane through the corresponding hoisting holes provided at the top of the climbing formwork cylinder frame. Each hoisting inductor detects whether the corresponding hoisting rope is located in the corresponding hoisting hole and sends the detected information to the controller. When there is a hoisting inductor that does not sense the contact with the corresponding hoisting rope, the controller displays "The preparation work for hoisting with four hoisting ropes is not completed. Please wait." on the operation screen provided inside the cylinder frame, and continues to wait until the hoisting preparation work is completed before starting the lifting operation. When all hoisting inductors sense the contact with the corresponding hoisting ropes, the controller displays "The preparation for hoisting with four hoisting ropes is completed. Do you want to unlock the hoisting lock?" on the operation screen. After the staff inside the cylinder frame clicks "Confirm", the hoisting lock is unlocked, and the operation screen displays "The lock has been unlocked. Do you want to start the hoisting operation?" Only after the staff inside the cylinder frame clicks "Confirm" can the lifting operation of the climbing formwork cylinder frame begin.

[0008] Preferably, in the above-mentioned method for using the climbing formwork cylinder frame with improved lifting safety performance, there is also an emergency stop switch. The emergency stop switch is provided inside the cylinder frame and is connected to the controller.

[0009] Preferably, in the above-mentioned method for using the climbing formwork cylinder frame with improved lifting safety performance, a friction tooth mechanism for deceleration is provided on each column. The friction tooth mechanism includes a number of friction teeth, a push-pull rod, and a tooth driving motor. The column is an L-shaped structure composed of an L-shaped inner wall, an L-shaped outer wall, and end plates on both sides. One end of each friction tooth is hinged to the L-shaped inner wall and is located inside the column. A strip-shaped through hole for the friction tooth to pass through is provided on the L-shaped outer wall. Each friction tooth is equally spaced and hinged to the push-pull rod near the other end of the friction tooth. The push-pull rod can, under the action of the tooth driving motor, cause the friction tooth to rub against the guide rail by retracting into the column or extending out of the through hole in the L-shaped outer wall. The tooth driving motor is connected to the controller. The friction tooth mechanism is linked with the emergency stop switch, and the friction tooth mechanism can be directly activated for friction deceleration through the emergency stop switch.

[0010] Preferably, in the above-mentioned method for using the climbing formwork cylinder frame with improved lifting safety performance, a safety airbag is provided inside each of the four columns. The safety airbag is connected to the controller. The safety airbag is linked with the emergency stop switch, and the safety airbag can be directly opened through the emergency stop switch.

[0011] Preferably, in the above method for using the climbing formwork cylinder frame capable of enhancing safety performance, there are also a number of buffer springs. The bottom plate of the cylinder frame body includes an upper bottom plate and a lower bottom plate. A sandwich layer is provided between the upper bottom plate and the lower bottom plate. The base of the buffer spring is installed on the lower surface of the upper bottom plate. Through holes for the corresponding buffer springs to extend out are opened on the lower bottom plate. There are a total of eight buffer springs, four of which are cylindrical springs respectively arranged at the four corner positions of the bottom plate, and four are conical springs evenly arranged in the central area of the bottom plate. The buffer springs are respectively connected to the controller, and the buffer springs are linked with the emergency stop switch. The buffer springs can be directly started to extend out of the corresponding through holes through the emergency stop switch.

[0012] Preferably, in the above method for using the climbing formwork cylinder frame capable of enhancing safety performance, there are also two limiters. One limiter is arranged on the cylinder frame body, and the other limiter is arranged on the upper part of the guide rail. The limiter is internally provided with a laser emitter and a laser receiver. The limiter can calculate the distance between the two limiters through the time required for the laser to reflect back. The limiter is connected to the controller. When the distance between the two limiters is less than the set value, the controller alarms through the alarm device.

[0013] Preferably, in the above method for using the climbing formwork cylinder frame capable of enhancing safety performance, there is also an acceleration sensor. The acceleration sensor is connected to the controller. When the acceleration sensed by the acceleration sensor is greater than the upper limit of the allowable range or lower than the lower limit of the allowable range, the controller sends a signal to the alarm device, and the alarm device gives an alarm.

[0014] Preferably, in the above method for using the climbing formwork cylinder frame capable of enhancing safety performance, the lifting sensor is a pressure sensor, and the lifting sensor is arranged at a position close to the central axis of the cylinder frame body above the corresponding lifting hole.

[0015] As can be seen from the above disclosed technical solutions, compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] The method for using the climbing formwork cylinder frame capable of enhancing safety performance provided by the present invention is to set a lifting sensor at the lifting hole of each lifting lug at the top of the four corners of the cylinder frame body, and set a lifting lock catch at the position close to the corner at the top of the cylinder frame body respectively. Grooves for the corresponding lifting lock catches to extend into are arranged at intervals along the longitudinal direction on the guide rail. When all the lifting sensors detect that the corresponding lifting ropes are in the corresponding lifting holes, the staff inside the cylinder frame body notify the controller to unlock the lifting lock catches through operating the display screen. After all the lifting lock catches are unlocked, the tower crane construction personnel can start to lift the climbing formwork cylinder frame, thereby ensuring that all four lifting lugs are stressed during the lifting process of the climbing formwork cylinder frame, effectively avoiding the safety accidents caused by the "double-point - diagonal" lifting method in the on-site construction process.

Detailed Description of the Preferred Embodiment

[0026] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. The technical content and features of the present invention will be described in detail below by the listed embodiments in conjunction with the accompanying drawings. It should be noted that the accompanying drawings are in very simplified forms and use non-precise scales, only for conveniently and clearly assisting in explaining the purpose of the embodiments of the present invention. For the sake of convenience of description, the "upper" and "lower" mentioned below are in the same directions as the upper and lower of the accompanying drawings, but this should not be a limitation to the technical solution of the present invention.

[0027] Please refer to Figures 1 to 8, this embodiment discloses a method for using a climbing formwork barrel frame that can enhance safety performance. The climbing formwork barrel frame includes a barrel frame body 3, a plurality of lifting lugs 5, a plurality of lifting sensors 7, a plurality of lifting lock catches 8, an operation display screen 9, and an alarm device 10. The barrel frame body 3 is a rectangular box structure with a closed bottom and an open top. At the top of each of the four corners of the barrel frame body 3, a lifting lug 5 is provided. The lifting lug 5 has a lifting hole 6 for a lifting rope 11 to pass through. A lifting sensor 7 is arranged in each lifting hole 6. The barrel frame body 3 can move up and down relative to the climbing formwork 1 under the lifting of a tower crane 2. Four vertical columns 4 are arranged around the barrel frame body 3. Guide rails 12 matching the corresponding columns 4 are provided on the climbing formwork 1. The operation display screen 9 is arranged inside the barrel frame body 3. The lifting sensors 7, the lifting lock catches 8, the operation display screen 9, and the alarm device 10 are respectively connected to a controller. The lifting sensor 7 can detect whether the lifting rope 11 is located in the corresponding lifting hole 6 and send the detected information to the controller. The lifting lock catches 8 are respectively arranged at positions near the corners at the top of the barrel frame body 3. Grooves for the corresponding lifting lock catches 8 to extend into are arranged at intervals along the longitudinal direction on the guide rails 12. The lifting lock catches 8 have two states of locking and unlocking under the action of the controller. When the lifting lock catches 8 are locked, the lifting lock catches 8 respectively extend into the corresponding grooves. When the lifting lock catches 8 are unlocked, the lifting lock catches 8 respectively leave the corresponding grooves. The method includes the following steps:

[0028] The on-site commander sends a signal to the crane operator. The crane operator makes preparations for lifting, passes the lifting rope 11 of the tower crane 2 through the corresponding lifting hole 6 arranged at the top of the climbing formwork barrel frame. Each lifting sensor 7 detects whether the corresponding lifting rope 11 is located in the corresponding lifting hole 6 and sends the detected information to the controller. When a lifting sensor 7 does not sense the contact with the corresponding lifting rope 11, that is, when a lifting sensor 7 does not sense the corresponding lifting rope 11, the controller displays "The lifting preparation work of the four lifting ropes 11 is not completed, please wait" through the operation screen arranged in the barrel frame body 3, and continues to wait until the lifting preparation work is completed before starting the lifting operation. When all lifting sensors 7 sense the contact with the corresponding lifting ropes 11, that is, when all lifting sensors 7 sense the corresponding lifting ropes 11, that is, when all lifting sensors 7 are pressed, all lifting ropes 11 are in a straight state but not under force. The controller displays "The lifting preparation of the four lifting ropes 11 is completed. Do you want to release the lifting lock catches 8" through the operation screen. After the staff inside the barrel frame body 3 clicks "Confirm", the lifting lock catches 8 are unlocked. The operation screen displays "The lock catches have been released. Do you want to start the lifting operation". Only after the staff inside the barrel frame body 3 clicks "Confirm" can the lifting operation of the climbing formwork barrel frame be started.

[0029] The usage method of the climbing formwork cylinder frame that can improve safety performance provided by the present invention is as follows: At each lifting hole 6 of each lifting lug 5 at the top of the four corners of the cylinder frame body 3, a synchronous lifting inductor 7 is arranged. At positions near the corners at the top of the cylinder frame body 3, synchronous lifting buckles 8 are respectively arranged. Along the longitudinal direction on the guide rail 12, grooves for the corresponding synchronous lifting buckles 8 to extend into are arranged at intervals. When all the synchronous lifting inductors 7 detect that the corresponding lifting ropes 11 are located in the corresponding lifting holes 6, the staff inside the cylinder frame body 3 notify the controller to unlock the synchronous lifting buckles 8 by operating the display screen 9. After all the synchronous lifting buckles 8 are unlocked, the tower crane 2 construction personnel can start to lift the climbing formwork cylinder frame, so as to ensure that all four lifting lugs 5 are stressed during the lifting process of the climbing formwork cylinder frame, effectively avoiding safety accidents caused by the "double-point - diagonal" lifting method in the on-site construction process.

[0030] Preferably, in the above-mentioned usage method of the climbing formwork cylinder frame that can improve safety performance, an acceleration inductor 16 is further included. The acceleration inductor 16 is connected to the controller. When the acceleration sensed by the acceleration inductor 16 is greater than the upper limit of the allowable range or lower than the lower limit of the allowable range, the controller sends a signal to the alarm device 10, and the alarm device 10 issues an alarm.

[0031] Preferably, in the above-mentioned usage method of the climbing formwork cylinder frame that can improve safety performance, an emergency stop switch 17 is further included. The emergency stop switch 17 is arranged inside the cylinder frame body 3, and the emergency stop switch 17 is connected to the controller. When the staff inside the cylinder frame body 3 realizes the risk of emergency falling of the climbing formwork cylinder frame or hears the alarm sound emitted by the alarm device 10, the emergency stop switch 17 can be activated.

[0032] Preferably, in the above method for using the climbing formwork barrel frame capable of enhancing safety performance, a friction tooth mechanism 13 for deceleration is provided on each upright column 4. The friction tooth mechanism 13 includes a number of friction teeth 13, a push-pull rod 14, and a tooth driving motor 15. The upright column 4 is an L-shaped structure composed of an L-shaped inner sidewall 41, an L-shaped outer sidewall 42, and end plates on both sides. One end of the friction tooth 13 is hinged to the L-shaped inner sidewall and is located inside the upright column 4. A strip-shaped through hole for the friction tooth 13 to pass through is formed on the L-shaped outer sidewall. Each friction tooth 13 is equally spaced and hinged to the push-pull rod 14 near the other end of the friction tooth 13. The push-pull rod 14 can, under the action of the tooth driving motor 15, cause the friction tooth 13 to be retracted into the upright column 4 or extend out of the through hole of the L-shaped outer sidewall to rub against the guide rail 12. The tooth driving motor 15 is connected to the controller. The friction tooth mechanism 13 is linked with the emergency stop switch 17, and the friction tooth mechanism 13 can be directly started through the emergency stop switch 17 for frictional deceleration. When the staff inside the barrel frame body 3 realizes the risk of an emergency fall of the climbing formwork barrel frame, the emergency stop switch 17 can be activated, and through the emergency stop switch 17, the controller is notified to start the friction tooth mechanism 13 inside the four upright columns 4 of the climbing formwork barrel frame, so that the push-pull rod 14 can, under the action of the tooth driving motor 15, cause the friction tooth 13 to extend out of the through hole of the L-shaped outer sidewall to rub against the guide rail 12, thereby increasing the reverse frictional force between the friction tooth 13 and the guide rail 12 to reduce the falling speed of the climbing formwork barrel frame and enhance the safety of the climbing formwork barrel frame.

[0033] Preferably, in the above method for using the climbing formwork barrel frame capable of enhancing safety performance, a safety airbag 18 is respectively provided inside the four upright columns 4. The safety airbag 18 is connected to the controller, and the safety airbag 18 is linked with the emergency stop switch 17. The safety airbag 18 can be directly opened through the emergency stop switch 17. When the staff inside the barrel frame body 3 realizes the risk of an emergency fall of the climbing formwork barrel frame, the emergency stop switch 17 can be activated, and through the emergency stop switch 17, the controller is notified to start the safety airbags 18 inside the four upright columns 4 on the four sides of the climbing formwork barrel frame. The activation of the safety airbag 18 mainly reduces the gravitational acceleration generated by the fall of the staff inside the barrel frame body 3 and reduces the injury caused by the falling force to the staff inside the barrel frame body 3.

[0034] Preferably, in the above-mentioned method for using the climbing formwork barrel frame that can enhance safety performance, it further includes a plurality of buffer springs. The bottom plate 19 of the barrel frame body 3 includes an upper bottom plate and a lower bottom plate. A sandwich layer is provided between the upper bottom plate and the lower bottom plate. The base of the buffer spring is installed on the lower surface of the upper bottom plate. Through holes for the corresponding buffer springs to extend out are provided on the lower bottom plate. There are a total of eight buffer springs, four of which are cylindrical springs 20, which are respectively arranged at the four corner positions of the bottom plate, and four are conical springs 21, which are evenly arranged in the central area of the bottom plate. The buffer springs are respectively connected to the controller, and the buffer springs are linked with the emergency stop switch 17. The buffer springs can be directly started to extend out of the corresponding through holes through the emergency stop switch 17. When the staff inside the barrel frame body 3 realizes the risk of an emergency fall of the climbing formwork barrel frame, the emergency stop switch 17 can be activated, and the buffer springs at the bottom of the climbing formwork barrel frame can be started through the emergency stop switch 17. The buffer springs can effectively counteract the high speed and great impact force generated by the fall, and minimize or even avoid the harm to personnel as much as possible.

[0035] Preferably, in the above-mentioned method for using the climbing formwork barrel frame that can enhance safety performance, it further includes two limiters. One limiter, namely the first limiter 22, is arranged on the barrel frame body 3, and the other limiter, namely the second limiter 23, is arranged on the upper part of the guide rail 12. The limiter is internally provided with a laser emitter and a laser receiver. The limiter can calculate the distance between the two limiters based on the time required for the laser to be reflected back. The limiter is connected to the controller. When the distance between the two limiters is less than the set value, the controller alarms through the alarm device 10. By setting two limiters and monitoring the distance between the two limiters in real time, it is possible to prevent the climbing height of the climbing formwork barrel frame from exceeding the height of the climbing formwork 1, and improve the safety of the climbing formwork 1.

[0036] Preferably, in the above-mentioned method for using the climbing formwork barrel frame that can enhance safety performance, the lifting inductor 7 is a pressure sensor, and the lifting inductor 7 is arranged at a position close to the central axis of the barrel frame body 3 above the corresponding lifting hole, so that the lifting inductor 7 can timely sense the pressure of the lifting rope 11.
