Description

Technical Field

[0001] The invention relates to the technical field of airspeed devices, in particular to a safety airspeed device for hoisting steel cables in construction. Background Art

[0002] Lifting equipment, such as cranes, is usually used in the construction process. Cranes are material handling machinery that use steel cables to lift or jack heavy objects. Cranes include frames, mechanisms (hoisting mechanisms, running mechanisms, rotating mechanisms, luffing mechanisms, etc.) and control systems. However, the airspeed device is part of the control system. The airspeed device is used to brake the faulty steel cable and gradually reduce the descent speed of the faulty steel cable to ensure that the heavy objects lifted by the steel cable will not fall directly.

[0003] The existing airspeed device still has the following defects during use:

[0004] 1. When the airspeed controller is in contact with the steel cable, the steel cable is exposed to the external environment and there is a lot of dust on the construction site. At the same time, some particles will be adsorbed on the surface of the steel cable, which will cause impurities on the surface of the steel cable to form bulges when the steel cable contacts the airspeed controller, resulting in incomplete contact between the surface of the steel cable and the airspeed controller, thereby reducing the contact area between the surface of the steel cable and the airspeed controller, thereby reducing the braking force of the airspeed controller on the steel cable, making it difficult for the airspeed controller to decelerate the steel cable after a failure of the steel cable, causing the hoisted object to fall heavily on the ground, which is easy to cause danger to ground personnel.

[0005] 2. Since the steel cable usually works at a high position, it is impossible to clean the surface of the steel cable when it is at a high position, resulting in more and more impurities on the surface of the steel cable. As a result, some impurities are pushed by other impurities to easily enter the interior of the steel cable, thereby increasing the difficulty of subsequent cleaning of the steel cable. At the same time, the entire machine needs to be stopped when cleaning the steel cable, which prolongs the working time of the steel cable and reduces the service life of the steel cable. Summary of the invention

[0006] In view of the above-mentioned shortcomings of the prior art, the present invention provides a safety airspeed device for lifting steel cables in construction, which can effectively solve the problems in the prior art that impurities exist on the surface of the steel cable and cannot fully contact the airspeed device, thereby reducing the braking force of the airspeed device on the steel cable, and impurities cannot be cleaned in time, causing some impurities to enter the interior of the steel cable, increasing the difficulty of subsequent cleaning of the steel cable.

By using the cleaning block 212 to spray the cleaning agent mist and using the bristles 213 to clean the surface of the steel cable body 104 during the descent process of the steel cable body 104, and using the multi-layer bristles 213 to brush the surface of the steel cable body 104, it is possible to ensure that the surface of the steel cable body 104 is thoroughly cleaned to prevent impurities from covering up the defects on the surface of the steel cable body 104.

[0044] As a preferred implementation in this embodiment, Figure 8 , Fig. 9 and Fig.10As shown, the bottom end of the agent storage box 208 is fixedly connected to a driving box 215, and the side of the driving box 215 away from the agent guide tube 209 is rotatably connected to a driving shaft 216, and the end of the driving shaft 216 located inside the driving box 215 is fixedly connected to a cam 217, and the inside of the driving box 215 is slidably connected to a lifting plate 218, and the top of the lifting plate 218 is fixedly connected to a spring 219, and the spring 219 is fixedly connected to the inner wall of the driving box 215, and the outer surface of the lifting plate 218 is fixedly connected to a lifting frame 220, and the lifting frame 220 is slidably connected to a side of the driving box 215 close to the driving shaft 216, and the end of the lifting frame 220 away from the driving box 215 is fixedly connected to a connecting frame 221, and the connecting frame 221 is slidably connected to the top of the agent storage box 208, and the end of the connecting frame 221 away from the lifting frame 220 is fixedly connected to a blocking block 22 2.

The air guide ring 226 is sleeved on the outer surface of the steel cable body 104. An air outlet is provided on a side of the air guide ring 226 close to the steel cable body 104. An air guide cavity is provided inside the air guide ring 226. The air guide cavity is connected with the air outlet. The inner wall of the air guide cavity is fixedly connected with an air guide pipe 225. The transmission shaft 223 penetrates and is rotatably connected to the end of the air guide pipe 225 away from the air guide ring 226. The end of the transmission shaft 223 located inside the air guide pipe 225 is fixedly connected with a fan blade 224. The end of the air guide pipe 225 away from the air guide ring 226 is provided with an air inlet. After cleaning, the surface of the cable body 104 is dried using the airflow ejected by the air guide ring 226 to ensure that the surface of the cable body 104 is in a dry state after cleaning to prevent the friction between the brake block 207 and the cable body 104 from being reduced.

[0045] As a preferred implementation in this embodiment, Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the early warning assembly 300 includes an early warning box 301, which is fixedly connected to the side of the installation box 101 away from the rotating shaft 102, and the inner wall of the early warning box 301 is rotatably connected to a control wheel 302, and the end of the control wheel 302 close to the installation roller 103 is fixedly connected to an integrated coupling shaft, which penetrates and is rotatably connected to the side of the installation box 101 close to the early warning box 301, and the integrated coupling shaft is fixedly connected to the end of the installation roller 103 away from the rotating shaft 102, and the outer surface of the control wheel 302 is elastically connected to a metal sheet 1 303, and the inner wall of the early warning box 301 is elastically connected to a metal sheet 2 304, and the bottom end of the early warning box 301 is fixedly connected to an early warning light 305, and the metal sheet 2 304 is electrically connected to the early warning light 305.

[0046] In this embodiment, Figure 1 and Figure 6 As shown, the brake cleaning mechanism 200 includes a mounting seat 201 and a brake shaft 203.

[0047] Compared with the prior art, the jacking frame 220 is used to measure the descending speed of the steel cable body 104. If the speed is too fast, the jacking frame 220 automatically controls the brake block 207 to move in opposite directions, thereby increasing the friction between the brake block 207 and the steel cable body 104, braking the steel cable body 104, and reducing the descending speed of the steel cable body 104. If the speed of the steel cable body 104 is too fast, the metal sheet 1 303 and the metal sheet 2 304 will be frequently contacted, causing the warning light 305 to flash too fast, promptly reminding the ground staff to leave the range of the hoisted object, and before the brake block 207 contacts the steel cable body 104, the surface of the steel cable body 104 is thoroughly cleaned and dried to prevent impurities from covering the defects on the surface of the steel cable body 104, and the friction between the brake block 207 and the steel cable body 104 is in a relatively stable state, so that the wear on the surface of the steel cable body 104 is in a stable state, thereby extending the service life of the steel cable body 104.

[0048] Working principle:

[0049] Initial limit:

[0050] Before using the airspeed device, the user needs to manually rotate the integrated sealing plug counterclockwise. Since the integrated sealing plug is threadedly connected to the top of the reservoir box 208, the integrated sealing plug gradually separates from the top of the reservoir box 208 during the counterclockwise rotation. When the integrated sealing plug is completely separated from the top of the reservoir box 208, the user uses a delivery pipe or other tools to inject the mixed detergent into the reservoir box 208 from the connection between the integrated sealing plug and the top of the reservoir box 208. At this time, the blocking block 222 is in a state of blocking the agent guide tube 209. After the injection is completed, the above steps are reversed to fix the integrated sealing plug to the top of the reservoir box 208 again. The remaining parts are as follows. Figures 1 to 11 Status shown;

[0051] At this time, there is a lifting object at the end of the steel cable body 104 away from the installation roller 103.

[0052] The user needs to connect a motor 1 to the rotating shaft 102, and the motor 1 serves as a driving source for the rotating shaft 102;

[0053] The user needs to connect the brake shaft 203 to the second motor, and the second motor serves as the driving source of the brake shaft 203;

[0054] The user needs to connect the drive shaft 216 to the external motor 3, and the motor 3 serves as the driving source of the drive shaft 216;

[0055] The user needs to install a controller inside the mounting base 201. The controller is electrically connected to the laser speed sensor body 227, and the motor 2 is electrically connected to the controller. The laser speed sensor body 227 measures the running speed of the object to be measured by laser and converts it into an output signal. After receiving the signal, the controller controls the running state of the motor 2, and the laser speed sensor body 227 is always in the open state.

[0056] Steps for lowering the cable body 104:

[0057] First, the user needs to turn on the power of motor 1 to start the motor working. Figure 3 As shown, the output shaft of the motor 1 drives the rotating shaft 102 to rotate clockwise, and the rotating shaft 102 synchronously drives the installation roller 103 to rotate clockwise during the clockwise rotation, and the installation roller 103 synchronously drives the steel cable body 104 to move downward during the clockwise rotation, thereby gradually moving the hoisted object closer to the ground;

[0058] The user turns on the power of the motor 3, causing the motor 3 to start working. The output shaft of the motor 3 drives the drive shaft 216 to rotate. The drive shaft 216 drives the cam 217 to rotate synchronously during the rotation process. Figure 8As shown, the cam 217 is located below the lifting plate 218, and the lifting plate 218 is slidably connected to the inside of the driving box 215, so that the lifting plate 218 is synchronously lifted during the rotation of the cam 217, so that the lifting plate 218 moves upward, and the lifting plate 218 presses the spring 219 synchronously during the upward movement, so that the spring 219 is deformed, and the lifting plate 218 synchronously drives the lifting frame 220 to move upward during the upward movement, and the lifting frame 220 synchronously drives the connecting frame 221 to move upward during the upward movement, and the connecting frame 221 synchronously drives the blocking block 222 to move upward during the upward movement, as shown in FIG. Fig. 9 As shown, the blocking block 222 moves upward to release the blockage of the agent guide tube 209, so that the detergent inside the agent storage box 208 enters the inside of the agent guide tube 209. When the cam 217 rotates to no longer contact the bottom end of the lifting plate 218, the lifting plate 218 is no longer lifted by the cam 217, causing the spring 219 to lose the pressure from the lifting plate 218, so that the lifting plate 218 moves downward by the rebound force of the spring 219, and the lifting plate 218 drives the blocking block 222 to move downward. The transmission principle is consistent with the above. When the blocking block 222 re-enters the inside of the agent guide tube 209, the blocking block 222 pushes the detergent inside the agent guide tube 209 close to the integrated atomizing plate, so that the detergent inside the agent guide tube 209 passes through a The integral atomizing plate forms a cleaning mist, which enters the inside of the shunt pipe 210, and then enters the inside of the bellows telescopic tube 211 from the inside of the shunt pipe 210, and then enters the cavity from the inside of the bellows telescopic tube 211, and then the cleaning mist is sprayed from the spray hole on the cleaning block 212 to the surface of the steel cable body 104, and the bristles 213 on the cleaning block 212 are used to brush the surface of the installation roller 103 during the descent of the steel cable body 104, so as to completely remove dust and impurities on the surface of the steel cable body 104, maintain the cleanliness of the surface of the steel cable body 104, and prevent impurities from covering up the defects on the surface of the steel cable body 104 during the maintenance of the steel cable body 104, and timely discover the damage or abnormality of the steel cable body 104 during the maintenance process;

[0059] like Fig. 9 and Fig.10As shown, the cam 217 synchronously drives the transmission shaft 223 to rotate during the rotation process, and the transmission shaft 223 synchronously drives the fan blade 224 to rotate during the rotation process. Since an air inlet hole is provided at one end of the air guide pipe 225 close to the fan blade 224, the fan blade 224 drives the external air to enter the interior of the air guide pipe 225 during the rotation process. Under the continuous rotation of the fan blade 224, the air is transported to the air guide cavity inside the air guide ring 226, and then the air is discharged from the air outlet hole connected to the air guide cavity, thereby drying the surface of the cleaned steel cable body 104 to avoid the steel cable body 104 from being easily adsorbed with new dust and impurities due to the wet surface, thereby ensuring that the contact area between the brake block 207 and the steel cable body 104 surface will not change, thereby making the friction between the brake block 207 and the steel cable body 104 in a relatively stable state, thereby extending the service life of the steel cable body 104;

[0060] Warning braking steps:

[0061] like Figure 3 and Figure 4 As shown, the installation roller 103 synchronously drives the integrated coupling to rotate clockwise during the clockwise rotation, and the integrated coupling synchronously drives the control wheel 302 to rotate clockwise during the clockwise rotation. The control wheel 302 synchronously drives the metal sheet 1 303 to rotate clockwise during the clockwise rotation. The metal sheet 1 303 comes into contact with the metal sheet 2 304 during the clockwise rotation, and the metal conductive property is used to cause the warning light 305 to light up. When the metal sheet 1 303 moves away from the metal sheet 2 304 during the clockwise rotation, the warning light 305 is in an off state. If the descending speed of the steel cable body 104 is abnormal, the rotation speed of the installation roller 103 gradually increases, and the rotation speed of the metal sheet 1 303 also gradually increases, causing the warning light 305 to light up and go out frequently. At this time, the ground staff can easily notice the frequent flashing state of the warning light 305, thereby warning the ground staff and reminding the staff to quickly leave the range of the hoisting object, thereby reducing the safety risk of the ground staff.

[0062] When the cable body 104 descends too fast, it is detected by the laser speed sensor body 227, causing the controller to control the motor 2 to turn on. The principle is the same as above, causing the motor 2 to start working. Figure 6As shown, the output shaft of the second motor drives the brake shaft 203 to rotate clockwise, and the brake shaft 203 synchronously drives the gear 204 to rotate clockwise during the clockwise rotation. Since the gear 204 is meshed with the rack 205 for transmission, the two racks 205 move relatively with the gear 204 as the center. The two racks 205 synchronously drive the two transmission frames 206 to move relatively during the relative movement. The two transmission frames 206 synchronously drive the two brake blocks 207 to move relatively with the steel cable body 104 as the center during the relative movement, so that the two brake blocks 207 are tightly attached to the surface of the steel cable body 104, thereby increasing the brake blocks 207 and the steel cable body 104. The friction force is used to brake the steel cable body 104, thereby reducing the descending speed of the steel cable body 104, so as to realize the double insurance of frequently flashing warning lights 305 to remind ground staff after the steel cable body 104 descends too fast, and using the relative movement of two brake blocks 207 to increase the friction between the brake blocks 207 and the steel cable body 104 to ensure that the ground staff have enough time to find abnormalities in the steel cable body 104, thereby ensuring the safety of the ground staff at work, and at the same time preventing the risk of hoisted objects falling from a height, reducing the probability of accidents, and ensuring that timely processing can be made after abnormalities in the steel cable body 104 occur.
