Description

Technical Field

[0002] A construction project refers to an engineering entity formed by the construction of various types of buildings and their ancillary facilities and the installation of supporting lines, pipelines, and equipment. In the process of construction, a lifting device is usually used to lift and install the building facilities used. Some lifting devices are equipped with a wire rope winding device on the lifting bracket. A wire rope is wound inside the wire rope winding device. A hook is provided at the other end of the wire rope. Multiple sets of movable pulleys are installed between the wire rope and the lifting device. The wire rope in this part is pulled and guided by the movable pulley. When lifting the building facilities, the building facilities are first hung on the hook, and then the driving element in the wire rope winding device is operated through the control element, so that the wire rope is retracted and released, and then To achieve the hoisting and movement of building facilities, when the hook part of the device hoists the building facilities, the lifting point of the building facilities is located inside the hook, and the hook safety buckle on the hook is used to prevent the two from falling off. However, the hook safety buckle can only limit the outermost end of the lifting port of the hook to prevent falling off, resulting in a moving gap between the hook and the lifting point of the building facilities. When the hook swings when lifting the building facilities, this moving gap will amplify the swing amplitude of the hook when lifting the building facilities. At the same time, during the process of the device lifting the building facilities, it is affected by the external environment, resulting in the hook and the wire rope being in an inclined state during the process of the device lifting the building facilities, so that the building facilities lifted by the hook are in a horizontally inclined state, affecting the lifting stability of the device for the building facilities.

[0024] The present invention provides an anti-falling hoist for installing building facilities, and its working principle is as follows: When the facility is hoisted and moved by the hoist during the installation of the building facility, the electric rotating table 2 is first started by the PLC controller 10 so that its rotating end drives the lifting bracket 3 to rotate horizontally, thereby adjusting the horizontal rotation position of the lifting part of the device according to the installation requirements of the building facility. The electric rotating table 2 is internally driven by a worm gear so that the rotating end drives the lifting bracket 3 to rotate forward and reversely. The PLC controller 10 starts the electro-hydraulic push rod 2 11 so that its telescopic end drives the lifting rod 4 to rotate around the axis of the second rotating shaft, thereby adjusting the lifting height of the lifting part of the device according to the installation requirements of the building facility. In this process, the telescopic end and the fixed end of the electro-hydraulic push rod 2 11 both rotate adaptively around the axis of the corresponding rotating shaft 3. The PLC controller 10 starts the electro-hydraulic push rod 3 12 so that its telescopic end drives the extension rod 5 to slide right along the inside of the lifting bracket 3, thereby adjusting the lifting horizontal extension length of the lifting part of the device according to the installation requirements of the building facility. During this process, the fixed end and the telescopic end of the electro-hydraulic push rod three 12 both adaptively rotate around the axis of the corresponding rotating shaft four, and then the PLC controller 10 starts the brake motor two 14 to make its output shaft drive the winding roller to rotate. Through the rotation of the winding roller, the lifting rope 6 is wound and retracted, thereby realizing the lifting height adjustment of the hook 7. During this process, the lifting rope 6 adaptively slides along the outer concave surface of the corresponding movable pulley 15. After the brake motor two 14 is energized, the internal armature of the brake motor two 14 is electromagnetically attracted, so that the brake disc is in a rotatable state and the brake motor two 14 rotates freely. When the brake motor two 14 loses power, the electromagnet loses power, and the armature is immediately supported by the spring, so that the brake disc and the rear end cover of the motor are pressed together and stop rotating. Therefore, the output shaft of the brake motor two 14 itself has a self-locking function, and the weight of the device itself is increased through the counterweight block 16 to avoid the overturning phenomenon caused by the excessive weight of the building facilities during the process of the device lifting the building facilities.

[0025] When the building facilities are hoisted and moved, the external rope is wound and fixed around the outer end of the building facilities, and then the central hanging end of the external rope is hung inside the hook 7, and then the flip shell 82 is reversed around the axis of the rotating shaft 81, so that the left end of the locking seat 83 in the flip shell 82 slides down around the outer arc surface of the hook 7, and the left end of the locking seat 83 is in a ratchet shape. During this process, the lower arc surface of the locking seat 83 contacts the upper arc surface of the adjacent ratchet 84, and the arc surfaces contact and pressurize each other, so that the locking seat 83 enters the interior of the flip shell 82, and the telescopic end of the telescopic column 86 and the spring 87 contract adaptively. When the flip shell 82 is reversed to contact the external rope The flip shell 82 is blocked by the central hanging end of the external rope and cannot be reversed. The compression force of the spring 87 causes the ratchet surface of the locking seat 83 to engage with the adjacent pawl 84, thereby locking the flip shell 82 from rotating forward around the axis of the shaft 81. While preventing the building facility from falling off during hoisting, the central hanging end of the external rope in the hook 7 occupies a hanging space, thereby reducing the relative movement between the central hanging end of the external rope and the hook 7 due to the large reserved hanging space during the hoisting and installation of the building facility, thereby improving the hoisting stability of the device for the building facility.

[0026] During the installation and lifting process of the device for building facilities, the battery 18 provides power support for the inclination sensor 96. The inclination sensor 96 has a module-integrated high-precision gyroscope, accelerometer, and geomagnetic field sensor. It uses a high-performance microprocessor and advanced dynamics solution and Kalman dynamic filtering algorithm to quickly solve the inclination angle of the hook 7 within the horizontal range. Then the inclination sensor 96 transmits the detection result to the wireless signal transmitter 17 in the form of an electrical signal. The wireless signal transmitter 17 transmits the detection result to the wireless signal receiver on the external PLC controller 10 in the form of wireless waves, and the inclination of the hook 7 within the horizontal range is transmitted through the wireless signal receiver. The bevel angle is transmitted to the PLC controller 10 in the form of an electrical signal. The PLC controller 10 starts the brake motor 993 so that its output shaft drives the bevel gear 991 to rotate through the rotating shaft 6. The bevel gear 991 is connected by meshing so that the bevel gear ring 992 drives the rotating ring 92 to rotate. The rotating ring 92 indirectly drives the correction ring 94 to rotate horizontally to the end where the hook 7 hoisting the building facilities is offset. In this process, the PLC controller 10 starts the angle sensor 98. The angle sensor 98 adopts a high-performance integrated magnetic sensitive element and uses the non-contact characteristics of magnetic signal induction to measure the horizontal rotation angle of the detection end and the synchronous frame 97, and measures the measured The result is transmitted to the PLC controller 2 in the form of an electrical signal. The PLC controller 10 controls the start and stop of the brake motor 993 according to the detection result, so that the correcting ring 94 rotates horizontally and accurately to the end where the hook 7 hoisting the building facility is offset. Then the PLC controller 10 controls the two electro-hydraulic push rods 93 to extend the telescopic end of the electro-hydraulic push rod 93 close to the offset end of the hook 7, and the telescopic end of the electro-hydraulic push rod 93 away from the offset end of the hook 7 contracts, so that the correcting ring 94 drives the lifting rope 6 to move back to the offset end of the hook 7, thereby automatically suspending and straightening the building facility hoisted by the hook 7, so that the building facility hoisted by the hook 7 is always in a vertical suspension state. state, so that the construction facilities hoisted under the hook 7 are in a horizontal force state, thereby improving the lifting stability of the device for the construction facilities. The PLC controller 10 controls the brake motor 1 993 through the angle sensor 98 so that the forward and reverse rotation of the rotating ring 92 does not exceed 360 degrees, thereby avoiding winding. When the device hoists the construction facilities, the contact seat 953 contacts the adjacent lifting rope 6, and through the elastic contraction of the spring 2 952 and the friction or hydraulic resistance of the elastic elements and the load-bearing elements inside the damper 951, the shaking interference force on the lifting part generated by the operation of the device itself is converted into heat energy release, thereby further improving the lifting and moving stability of the device for the construction facilities.
