Description

Technical Field

[0001] This utility model relates to the field of tower crane safety technology, and in particular to a mobile tower crane rail clamp detection device. Background Technology

[0002] In the modern construction industry, mobile tower cranes, with their high lifting capacity and flexible mobility, have become indispensable key equipment in the construction of high-rise buildings and large-scale infrastructure. However, the safety of tower crane operation remains a core focus of the industry, especially the stable operation of mobile tower cranes on the tracks, which is closely related to the reliable working condition of the rail clamps. Therefore, developing a precise and reliable detection device for mobile tower crane rail clamps is of great significance for ensuring construction safety and improving construction efficiency.

[0003] Currently, when a mobile tower crane stops working on the track, it is usually secured to the track by manually operating rail clamps to prevent it from sliding due to external forces. When the tower crane needs to move again, the staff will manually open the rail clamps to allow the tower crane to move freely on the track. This manual operation method mainly relies on the experience and sense of responsibility of the staff and lacks effective automated detection methods.

[0004] However, in actual construction, due to the complex environment and heavy workload at the construction site, workers may easily forget to open the rail clamps before starting the traveling tower crane due to momentary negligence, and then directly drive the tower crane to run. At this time, the tower crane clamped by the rail clamps will shake violently during operation, which not only seriously affects the normal operation of the tower crane, but also easily causes safety accidents, resulting in equipment damage and personal injury, bringing huge safety hazards and economic losses to the construction. Therefore, a traveling tower crane rail clamp detection device is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides a rail clamp detection device for mobile tower cranes, which aims to improve the problem that workers usually manually open the rail clamps before the mobile tower crane moves, and workers are prone to momentary negligence that may result in the rail clamps not being opened, leading to safety accidents.

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

[0007] The mobile tower crane rail clamp detection device includes a clamping block one and a clamping block two. A rotating shaft is rotatably connected between the clamping block one and the clamping block two. A bidirectional threaded rod is threaded inside the clamping block one and the clamping block two. Connecting plates are fixedly connected to both sides of the inner wall of the clamping block two. Multiple fixing plates are fixedly connected to the outer wall of the rotating shaft. A touch switch one and a touch switch two are fixedly connected to one side of each fixing plate. Each connecting plate and touch switch one are in contact with each other. Indicator light one and indicator light two are fixedly connected to both sides of the top of each fixing plate.

[0008] As a further description of the above technical solution:

[0009] Multiple connecting plates are rotatably connected to the inner wall of the rotating shaft, and each connecting plate is in contact with a fixed plate.

[0010] As a further description of the above technical solution:

[0011] Each of the two touch switches is electrically connected on one side to the outer wall of the first indicator light, and each of the two touch switches is electrically connected on one side to the outer wall of the second indicator light.

[0012] As a further description of the above technical solution:

[0013] The clamping blocks one and two are fitted together, and a handle is fixedly connected to one end of the bidirectional threaded rod. The two ends of the handle extend through to the outside of the bidirectional threaded rod.

[0014] As a further description of the above technical solution:

[0015] Both sides of the clamping block are threaded with fixing bolts, and one end of each fixing bolt passes through the connecting plate and extends to one side of the fixing plate.

[0016] As a further description of the above technical solution:

[0017] Each of the fixing bolts has a nut threaded onto one end, and each nut is fitted against one side of the fixing plate.

[0018] This utility model has the following beneficial effects:

[0019] In this invention, the connecting plate touches either touch switch one or touch switch two, causing indicator light one or indicator light two to light up. By observing the light status of indicator light one and indicator light two, the state of the equipment can be determined, achieving the equipment detection effect. This solves the problem that before the mobile tower crane moves, the operator usually manually opens the rail clamps, and the operator may easily be negligent and fail to open the rail clamps, resulting in a safety accident. This enhances the safety of the mobile tower crane during use. Attached Figure Description

[0027] 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.

[0028] Reference Figures 1-5This utility model provides an embodiment of a mobile tower crane rail clamp detection device, comprising a clamping block 1 and a clamping block 2. A rotating shaft 3 is rotatably connected between clamping blocks 1 and 2. The rotating shaft 3, in conjunction with clamping blocks 1 and 2, rotates to adjust the rail clamp's state. A bidirectional threaded rod 4 is threaded inside clamping blocks 1 and 2, driving relative movement between them, thus achieving the clamping and releasing function of the rail clamp. Connecting plates 5 are fixedly connected to both sides of the inner wall of clamping block 2, contacting touch switches 1 and 2, enabling detection and feedback of the equipment's state. Multiple fixing plates 9 are fixedly connected to the outer wall of the rotating shaft 3, fixing touch switches 1 and 2. 7. To ensure the stability of the switch position, each fixed plate 9 is fixedly connected to one side with a first touch switch 6 and a second touch switch 7. The first touch switch 6 and the second touch switch 7 are used to detect the position of the connecting plate 5, realizing automatic identification of the equipment status. Each connecting plate 5 and the first touch switch 6 are in contact with each other. The contact between the connecting plate 5 and the first touch switch 6 triggers the second indicator light 12 to turn off, indicating a change in the equipment status. Each fixed plate 9 has a first indicator light 8 and a second indicator light 12 fixedly connected to its top two sides respectively. The first indicator light 8 and the second indicator light 12 are used to display the upper or lower hanging status of the equipment, facilitating intuitive judgment by the staff. Multiple connecting plates 5 are rotatably connected to the inner wall of the rotating shaft 3. The rotation of the connecting plates 5 drives the first touch switch 6 or the second touch switch 7 to activate. The device switches between states. Each connecting plate 5 is attached to the fixing plate 9, ensuring stability when the device is in a fixed state. One side of each touch switch 7 is electrically connected to the outer wall of indicator light 8. This connection illuminates indicator light 8 in the hanging state, providing visual feedback. One side of each touch switch 6 is electrically connected to the outer wall of indicator light 12. This connection illuminates indicator light 12 in the hanging state, providing visual feedback. Clamping blocks 1 and 2 are attached to each other, clamping the rail to ensure the device is fixed in a non-moving state. One end of the bidirectional threaded rod 4 is internally fixed. A handle 13 is attached, which is used to manually rotate the bidirectional threaded rod 4, facilitating the operator's adjustment of the rail clamp's position. Both ends of the handle 13 extend through to the outside of the bidirectional threaded rod 4. The extended design of the handle 13 makes it easier for the operator to grip, improving operational convenience. Both sides of the clamping block 2 are internally threaded with fixing bolts 10, which are used to fix the position of the clamping block 2 and the connecting plate 5, enhancing the stability of the equipment after adjustment. One end of each fixing bolt 10 passes through the connecting plate 5 and extends to one side of the fixing plate 9. The through-through design of the fixing bolts 10 ensures the connection strength between the clamping block 2 and the fixing plate 9. A nut 11 is threadedly connected to one end of each fixing bolt 10, which is used to lock the fixing bolt 10 and prevent it from loosening.Each nut 11 is fitted against one side of the fixing plate 9, and the fit between the nut 11 and the fixing plate 9 ensures the tightening effect of the fixing bolt 10.

[0029] Working principle: When the equipment is adjusted to the hanging position, separate the fixing bolt 10 and nut 11 from the outer wall of clamping block 2 and fixing plate 9. Then, grasp the handle 13 and push the double-threaded rod 4 to rotate, causing clamping block 1 and clamping block 2 to rotate around the pivot 3. As clamping block 2 rotates, it will cause the connecting plate 5 to separate from the side of touch switch 6. At this time, the indicator light on the surface of indicator light 12 will turn off. When the side of connecting plate 5 is in contact with touch switch 7, the indicator light on indicator light 8 will light up. At this time, the equipment is in the hanging position. Then, the fixing bolt 10 is inserted through clamping block 2, connecting plate 5 and fixing plate 9, and the nut 11 is screwed into one end of the fixing bolt 10 to enhance the fixing effect of clamping block 2. When the equipment needs to be adjusted to the hanging position, Based on the same principle, the other side of the connecting plate 5 is rotated to the surface of the touch switch 6. At this time, the indicator light 12 will light up. By observing the light status of indicator lights 8 and 12, the status of the equipment can be determined. The light status will be displayed in the background, which makes it convenient for personnel who are not on site to accurately judge the status of the equipment. This achieves the effect of equipment detection and solves the problem that before the traveling tower crane moves, the staff usually manually opens the rail clamps. However, the staff may be negligent and fail to open the rail clamps, and directly drive the traveling tower crane to run. The traveling tower crane is restricted by the rail clamps and is prone to violent shaking, which affects the operation of the traveling tower crane and leads to safety accidents. This enhances the safety of traveling tower cranes during use.
