Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a positioning mechanism for a tower crane hook in building construction. Background Technology

[0002] With the expansion of construction projects and the increasing requirements for construction safety, tower cranes are being used more and more widely in modern construction. The demand for hook positioning devices is gradually increasing, especially in the construction of high-rise buildings and complex structures. Precise hook positioning and safety protection have become key technical requirements to ensure that the hook remains stable during operation, avoid operational errors or equipment damage caused by inaccurate positioning, and reduce safety accidents caused by hook position errors.

[0003] Currently, there are various types of tower crane hook positioning mechanisms on the market. However, the installation and maintenance of these devices usually require complex manual adjustments. This process not only increases the labor intensity of operators but also reduces work efficiency, which to some extent affects the construction progress and overall work efficiency. Utility Model Content

[0004] This invention addresses the problem that some devices on the market require complex manual adjustments during sensor installation and maintenance, which not only increases the labor intensity of operators but also reduces work efficiency, affecting construction progress and overall work efficiency to some extent. Therefore, it provides a tower crane hook positioning mechanism for construction.

[0005] This utility model is achieved by the following technical solution: a positioning mechanism for a tower crane hook in construction, comprising a limiting mechanism, an auxiliary mechanism and a protective mechanism, wherein the limiting mechanism is located at the front end of the protective mechanism and the auxiliary mechanism is located inside the limiting mechanism; The limiting mechanism includes a housing, a knob rotatably connected to the upper end of the housing, a threaded rod fixedly connected to the bottom of the knob, a movable block threadedly connected to the surface of the threaded rod, a limiting plate fixedly connected to one side of the movable block, a connecting plate slidably connected to the bottom of the limiting plate, a sensor body fixedly connected to the bottom of the connecting plate, a camera fixedly connected to the bottom of the sensor body, and a laser sensor fixedly connected to the bottom of the sensor body.

[0006] The laser sensor, model LJ-V7000, features high resolution and fast response, making it suitable for high-precision measurement. It ensures safe operation of the hook by accurately measuring distances and avoiding collisions, while the camera provides real-time visual feedback, allowing operators to understand the overall situation of the work area at any time.

[0007] As a further improvement to the above solution, the limiting plate is located on the left side of the moving block, and the laser sensor is located on the right side of the camera.

[0008] As a further improvement to the above solution, the threaded rod is rotatably connected to the inner wall of the housing, and the limiting plate is located inside the housing.

[0009] By using the above technical solution, the position of the limit plate can be adjusted by rotating the threaded rod, which can achieve precise control of the sensor body, ensure that it can maintain a proper fixed position in the working state, and avoid unnecessary displacement or vibration during hook operation.

[0010] As a further improvement to the above solution, the auxiliary mechanism includes a baffle, an inclined block slidably connected to the inner wall of the baffle, a slider fixedly connected to the surface of the inclined block, a cylinder fixedly connected to the bottom of the inclined block, and a spring sleeved on the surface of the cylinder.

[0011] With the above technical solution, when the operator slides the slider, the inclined block can enter the interior of the baffle, and the cylinder will also slide downward inside the baffle.

[0012] As a further improvement to the above solution, the baffle is rotatably connected to the inner wall of the housing, and the cylinder is slidably connected to the inner wall of the baffle.

[0013] Through the above technical solution, the cooperation between the cylinder and the spring can ensure that the baffle remains in a fixed position when there is no external force, thereby improving the overall stability of the device.

[0014] As a further improvement to the above solution, the slider is located on the left side of the baffle, and the spring is located inside the baffle.

[0015] As a further improvement to the above solution, the protective mechanism includes a support frame, with pulleys rotatably connected to the inner wall of the support frame, and a hook body fixedly connected to the bottom of the support frame.

[0016] Through the above technical solution, the support frame achieves smooth sliding on the tower arm through pulleys, and the hook body is fixed at the bottom of the support frame, effectively ensuring the stability and flexibility of the hook body.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention utilizes a limiting mechanism. The operator pushes the sensor body into the housing, simultaneously pushing in the connecting plate. The inner wall of the connecting plate slides against the surface of the limiting plate, thus limiting the sensor body. Once the sensor body is fully inside the housing, the operator rotates a knob. The knob rotates the threaded rod, causing the moving block to move downwards. This downward movement of the moving block moves the limiting plate downwards as well, allowing the sensor body to precisely move to the bottom of the housing. This ensures that the camera and laser sensor are positioned within the recess of the housing. The entire operation is convenient and quick, further accelerating the operator's installation and disassembly efficiency, while also ensuring the stability of the sensor body inside the housing.

[0018] This utility model, by setting up an auxiliary mechanism, allows the operator to slide the slider to move the inclined block into the inside of the baffle, thereby removing the baffle's restriction on the housing and facilitating subsequent installation and maintenance of the sensor body. After releasing the slider, the spring loses its compressive force and pushes the inclined block again, thus restoring the restriction on the housing and achieving effective protection of the sensor body inside the housing.

Detailed Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0022] Example: Please combine Figure 1-5The present embodiment of a tower crane hook positioning mechanism for construction includes a limiting mechanism 1, an auxiliary mechanism 2 and a protective mechanism 3. The limiting mechanism 1 is located at the front end of the protective mechanism 3, and the auxiliary mechanism 2 is located inside the limiting mechanism 1. The limiting mechanism 1 includes a housing 11. A knob 12 is rotatably connected to the upper end of the housing 11. A threaded rod 13 is fixedly connected to the bottom of the knob 12. A moving block 14 is threadedly connected to the surface of the threaded rod 13. A limiting plate 15 is fixedly connected to one side of the moving block 14. A connecting plate 16 is slidably connected to the bottom of the limiting plate 15. A sensor body 17 is fixedly connected to the bottom of the connecting plate 16. A camera 18 is fixedly connected to the bottom of the sensor body 17. A laser sensor 19 is fixedly connected to the bottom of the sensor body 17. The data collected by the camera 18 and the laser sensor 19 are transmitted in real time to the tower crane operator's display screen through the sensor body 17. The operator can comprehensively monitor the dynamic situation of the work area through the display screen, which improves the safety and efficiency of the operation.

[0023] The limiting plate 15 is located to the left of the moving block 14, and the laser sensor 19 is located to the right of the camera 18.

[0024] The threaded rod 13 is rotatably connected to the inner wall of the housing 11, and the limiting plate 15 is located inside the housing 11. By rotating the threaded rod 13 to adjust the position of the limiting plate 15, precise control of the sensor body 17 can be achieved, ensuring that it can maintain a suitable fixed position in the working state and avoiding unnecessary displacement or vibration during hook operation.

[0025] The auxiliary mechanism 2 includes a baffle 21, an inclined block 22 slidably connected to the inner wall of the baffle 21, a slider 23 fixedly connected to the surface of the inclined block 22, a cylinder 24 fixedly connected to the bottom of the inclined block 22, and a spring 25 sleeved on the surface of the cylinder 24. When the operator slides the slider 23, the inclined block 22 can enter the interior of the baffle 21, and the cylinder 24 will also slide downward inside the baffle 21.

[0026] The baffle 21 is rotatably connected to the inner wall of the housing 11, and the cylinder 24 is slidably connected to the inner wall of the baffle 21. The cylinder 24 and the spring 25 cooperate with each other to ensure that the baffle 21 always remains in a fixed position when there is no external force intervention, thereby improving the overall stability of the device.

[0027] The slider 23 is located on the left side of the baffle 21, and the spring 25 is located inside the baffle 21.

[0028] The protective mechanism 3 includes a support frame 31, with pulleys 32 rotatably connected to the inner wall of the support frame 31, and a hook body 33 fixedly connected to the bottom of the support frame 31. The support frame 31 achieves smooth sliding on the tower arm through the pulleys 32, and the hook body 33 is fixed to the bottom of the support frame 31, effectively ensuring the stability and flexibility of the hook body 33.

[0029] The implementation principle of the tower crane hook positioning mechanism in this application embodiment is as follows: The operator pushes the sensor body 17 into the housing 11, and the connecting plate 16 is also pushed into the housing 11. At this time, the inner wall of the connecting plate 16 slides on the surface of the limiting plate 15 to limit the sensor body 17. After the sensor body 17 is completely pushed into the housing 11, the operator starts to rotate the knob 12. The knob 12 can drive the threaded rod 13 to rotate together, thereby causing the moving block 14 to move downward. Then, the downward moving block 14 can drive the limiting plate 15 to move downward. 5. Moving downwards together, because at this time the sensor body 17 is merged with the limiting plate 15 through the connecting plate 16, the sensor body 17 will also move downwards along with the limiting plate 15, eventually moving the sensor body 17 to the bottom of the housing 11. The limiting plate 15 can effectively limit the sensor body 17, further ensuring the stability of the sensor body 17 when it is inside the housing 11. At this time, the camera 18 and the laser sensor 19 will be located in the groove at the bottom of the housing 11. The laser sensor 19 can emit a laser beam towards the target. When the laser beam hits the target object, part of the light... The light will be reflected back. The sensor body 17 then calculates the time difference between the emission and reception of the reflected light to accurately measure the distance to the object. By monitoring the height of the hook above the ground in real time, it prevents the hook from colliding with other objects, thus ensuring safety during tower crane operation. The camera 18 provides real-time video images to help operators observe the situation at the tower crane operation site, ensuring the safety of the hook, load, and surrounding environment. Data collected by the camera 18 and laser sensor 19 is transmitted in real time to the tower crane operator's display screen via the sensor body 17, enabling the operator to comprehensively monitor the dynamic situation of the entire operation area. This improves the safety and efficiency of the operation. The operator slides the slider 23 to move the inclined block 22 into the inside of the baffle 21, thereby removing the baffle 21 from the housing 11 and making it easier for the operator to install and maintain the sensor body 17. After the slider 23 is released, the spring 25 loses its squeezing force and pushes the inclined block 22 again, thereby limiting the housing 11. The support frame 31 can slide on the tower arm through the pulley 32 and lift the object through the hook body 33. The whole device can realize the rapid installation and disassembly of the sensor body 17, further speeding up the operator's work efficiency.

Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
