Description

Technical Field

[0001] This utility model relates to the field of anemometer technology, and in particular to an anemometer for tower cranes. Background Technology

[0002] In the field of modern construction, tower cranes, as key lifting equipment, are widely used in various engineering projects. Their working environment is complex and changeable, and wind speed is one of the important factors affecting the safe and stable operation of tower cranes. Therefore, it is particularly important to accurately measure the wind speed at the construction site. Tower crane anemometers have emerged to address this need. They can monitor wind speed in real time and provide tower crane operators with accurate wind speed data, thereby ensuring that the tower crane operates within a safe wind speed range, effectively preventing safety accidents caused by strong winds, protecting the lives of construction workers, and ensuring the smooth progress of engineering projects.

[0003] Currently, most anemometers used on tower cranes on the market employ simple fixed brackets to install the anemometer sensor at specific locations on the tower crane, such as the top of the tower crane cab or the front of the boom. In terms of technical principle, most anemometers use cup-type sensors, where the rotation of the cup under the action of wind drives the internal gear mechanism to rotate, thereby converting the mechanical rotation into an electrical signal to measure the wind speed.

[0004] However, existing technologies have a prominent problem: tower cranes generate strong vibrations during operation, and the existing simple fixed support structures cannot effectively buffer and absorb these vibrations. This results in vibrations being easily transmitted to the anemometer sensor, affecting the normal operation of the precision components inside the sensor, reducing measurement accuracy, and causing deviations in the measured wind speed data. Furthermore, long-term and frequent vibration impacts can damage sensor components, shorten the anemometer's lifespan, increase equipment maintenance costs, and increase the risk of downtime due to equipment failure. Therefore, a tower crane anemometer is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a tower crane anemometer, which aims to improve the problems of existing tower crane anemometers that cannot effectively buffer tower crane vibration due to simple fixed supports, resulting in decreased measurement accuracy, easy sensor damage, and increased maintenance costs.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A tower crane anemometer includes an anemometer body and a crane column, wherein a buffer assembly is provided at the bottom of the anemometer body.

[0008] The buffer assembly includes a connecting shaft slidably connected to the outer wall of the anemometer body. A connecting ring is fixedly connected to the inner wall of the connecting shaft, and a fixing ring is fixedly connected to the inner wall of the connecting ring. A pulley is rotatably connected to the outer wall of the fixing ring, and the pulley contacts the outer wall of the anemometer body. A support plate is fixedly connected to the inner wall of the connecting shaft, and a support rod is fixedly connected to the top of the support plate. A sliding rod is slidably connected inside the support rod, and a spring is provided on the outer wall of the sliding rod. One end of the spring is fixedly connected to the side wall of the support rod, and the other end is fixedly connected to the side wall of the sliding rod. A connecting plate is fixedly connected to the top of the sliding rod, and the connecting plate is fixedly connected to the bottom of the anemometer body. A connecting assembly is provided at the bottom of the connecting shaft.

[0009] As a further description of the above technical solution:

[0010] The connecting assembly includes a first connecting block and a second connecting block. The upper surface of the first connecting block is fixedly connected to the lower surface of the connecting shaft, and the second connecting block is slidably connected to the outer wall of the crane column.

[0011] As a further description of the above technical solution:

[0012] The second connecting block has a fixed shaft that is symmetrically connected to the inside, and the first connecting block has a slot that is symmetrically opened to the inside.

[0013] As a further description of the above technical solution:

[0014] A drive shaft is slidably connected inside the fixed shaft, and a knob is fixedly connected to the bottom end of the drive shaft.

[0015] As a further description of the above technical solution:

[0016] A rotating disk is fixedly connected to the outer wall of the drive shaft, and a connecting disk is slidably connected to the outer wall of the rotating disk.

[0017] As a further description of the above technical solution:

[0018] The connecting disc is slidably connected to the inner wall of the fixed shaft, and a locking post is fixedly connected to the outer wall of the transmission shaft.

[0019] As a further description of the above technical solution:

[0020] The engaging post engages with the slot, and a spring is provided on the outer wall of the drive shaft.

[0021] As a further description of the above technical solution:

[0022] One end of the spring is fixedly connected to the side wall of the connecting disc, and the other end is fixedly connected to the inner wall of the fixed shaft.

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, the sliding rod slides inside the support rod, further compressing the spring, causing the spring to undergo elastic deformation, absorbing the vibration force during the operation of the crane, thereby achieving the effect of buffering and protecting the anemometer. This solves the problem that the anemometer's measurement accuracy is affected by the vibration of the tower crane and the sensor is easily damaged, thus improving the anemometer's service life and measurement efficiency.

[0025] 2. In this utility model, pressing the drive shaft causes the locking column to engage inside the slot, further causing the second spring to undergo elastic deformation. Then, by rotating the knob, the locking column is simultaneously deflected inside the slot. The elastic restoring force of the second spring provides a reverse force to the locking column, making the locking column fit tightly against the inner wall of the slot. This achieves the effect of quickly installing the anemometer, solving the problems of cumbersome installation and disassembly, time and manpower consumption of traditional anemometers, and improving the efficiency of anemometer installation and replacement.

Detailed Implementation

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] Reference Figure 1 - Figure 4 An embodiment of this utility model is provided: a tower crane anemometer, including anemometer body 1 and crane column 2. A buffer component is provided at the bottom of the anemometer body 1, which is used to buffer the vibration force generated during the operation of the crane.

[0036] The buffer assembly includes a connecting shaft 3, which is slidably connected to the outer wall of the anemometer body 1. The connecting shaft 3 provides a stable connection and support for the buffer assembly. A connecting ring 4 is fixedly connected to the inner wall of the connecting shaft 3, and a fixing ring 5 is fixedly connected to the inner wall of the connecting ring 4. A pulley 6, made of rubber, is rotatably connected to the outer wall of the fixing ring 5. The pulley 6 guides the sliding movement of the anemometer body 1, further ensuring its stability. The pulley 6 contacts the outer wall of the anemometer body 1. A support plate 7 is fixedly connected to the inner wall of the connecting shaft 3. A support rod 8 is fixedly connected to the top of the support plate 7. A sliding rod 9 is slidably connected inside the support rod 8. A spring 10 is provided on the outer wall of the sliding rod 9. The function of the spring 10 is to quickly absorb and buffer the vibration force of the crane by relying on its own elastic deformation. One end of the spring 10 is fixedly connected to the side wall of the support rod 8, and the other end is fixedly connected to the side wall of the sliding rod 9. A connecting plate 11 is fixedly connected to the top of the sliding rod 9. The connecting plate 11 is fixedly connected to the bottom of the anemometer body 1. A connecting assembly is provided at the bottom of the connecting shaft 3. The connecting assembly is used to facilitate the user to quickly connect and install the equipment.

[0037] Specifically, when the strong vibrations generated by the tower crane during operation affect the normal operation of the precision components of the anemometer sensor, reduce measurement accuracy, or cause damage to the sensor components due to long-term vibration and impact, increasing maintenance costs and downtime risks, the device is first installed by the operator in an unobstructed position on the crane. The anemometer body 1 is responsible for real-time monitoring of wind speed. When the crane is working, the anemometer body 1 will be affected by the vibration force generated during the crane's operation. In order to reduce the impact of these vibrations on wind speed measurement, the sliding rod 9 slides inside the support rod 8 under the guidance of the support rod 8. During the sliding process, the spring 10 will undergo elastic deformation, storing elastic potential energy while absorbing it. The vibration transmitted from the crane is not only partially eliminated by the deformation of spring 10, but also causes the anemometer body 1 to slide slightly up and down, thus allowing the anemometer body 1 to continue working in a stable state. While the anemometer body 1 is moving, it also drives the pulley 6 to roll. The pulley 6 cooperates with the fixed ring 5, and the rolling of the pulley 6 provides smooth guidance for the anemometer body 1. In this way, the anemometer body 1 can maintain higher stability during operation, avoiding the serious vibration generated by the crane operation from causing significant interference to the equipment. In addition, the movement of the pulley 6 can also help the anemometer body 1 to accurately adjust its position, ensuring the accuracy of its measurement function.

[0038] Reference Figure 5 and 6The connecting assembly includes connecting block 12 and connecting block 23. The upper surface of connecting block 12 is fixedly connected to the lower surface of connecting shaft 3. Connecting block 23 is slidably connected to the outer wall of crane column 2. The function of connecting blocks 12 and 23 in the connecting assembly is to provide stable support and connection for the connecting assembly. A symmetrical fixed shaft 14 is fixedly connected inside connecting block 23. A symmetrical slot 15 is opened inside connecting block 12. The slot 15 is used to cooperate with other components to achieve quick locking of the connecting assembly. A drive shaft 16 is slidably connected inside the fixed shaft 14. A knob 17 is fixedly connected to the bottom end of the drive shaft 16. The knob 17 is used to provide convenient operation for the operator. It is made of rubber to increase the comfort of the operator's hands. Friction is used to connect the outer wall of the drive shaft 16 to a rotating disk 19, and a connecting disk 18 is slidably connected to the outer wall of the rotating disk 19. The connecting disk 18 is slidably connected to the inner wall of the fixed shaft 14. A locking post 20 is fixedly connected to the outer wall of the drive shaft 16. The locking post 20 fits into the slot 15. Through the cooperation between the locking post 20 and the slot 15, the connection components can be quickly locked and unlocked, which makes it convenient for operators to quickly install and disassemble the equipment without additional tools. A second spring 21 is provided on the outer wall of the drive shaft 16. The function of the second spring 21 is to provide a reverse pulling force to the locking post 20 to ensure that the locking post 20 can fit tightly against the inner wall of the slot 15. One end of the second spring 21 is fixedly connected to the side wall of the connecting disk 18, and the other end is fixedly connected to the inner wall of the fixed shaft 14.

[0039] Specifically, when it is necessary to conveniently install and disassemble the anemometer on the tower crane to avoid cumbersome installation procedures that delay tower crane operations, or when the anemometer malfunctions and needs to be quickly replaced with a new device, the operator first presses the knob 17 to trigger the sliding of the drive shaft 16 within the connecting plate 18. The movement of the connecting plate 18 will further compress the spring 21, causing it to undergo elastic deformation. During the deformation process, the spring 21 will reduce its reverse force on the drive shaft 16, thereby reducing the tight fit between the locking column 20 and the inner wall of the slot 15, allowing the locking column 20 to smoothly disengage from the slot 15. After unlocking, the operator can rotate the knob 17 to drive the locking column 20 to rotate, completing the unlocking operation. At this time, the anemometer body 1 can be easily disassembled without tools, facilitating the operator's maintenance and replacement of the equipment.

[0040] Working Principle: When using this anemometer, the operator first installs the device in an unobstructed position on the crane. The anemometer body 1 detects the wind speed. During the detection process, when the anemometer body 1 is affected by the vibration force generated by the crane's operation, the vibration force drives the sliding rod 9 to slide inside the support rod 8. As the sliding rod 9 slides, it further compresses the spring 10, causing the spring 10 to undergo elastic deformation simultaneously. While storing elastic potential energy, it also absorbs the vibration transmitted by the crane. Simultaneously, the elastic deformation of the spring 10 causes the anemometer body 1 to slide up and down slightly. As the anemometer body 1 slides, its outer wall drives the pulley 6 to roll synchronously on the outer wall of the fixed ring 5. The movement of the pulley 6 provides stable guidance for the anemometer body 1, thereby further... To ensure the stability of the anemometer body 1 and prevent significant impact from the crane during operation, the anemometer body 1 is disassembled by pressing knob 17. This causes the drive shaft 16 to slide within the connecting plate 18 and the fixed shaft 14. The movement of the connecting plate 18 further compresses the second spring 21, causing it to elastically deform. When the second spring 21 elastically deforms, the reverse force it exerts on the drive shaft 16 disappears, preventing the locking column 20 from tightly adhering to the inner wall of the slot 15. Then, by rotating knob 17, the locking column 20 is rotated, thus unlocking the device. After unlocking, the operator can quickly maintain and replace the equipment without using tools, providing convenience for the operator.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
