Description

Technical Field

[0001] This utility model relates to the technical field of struts in climbing frames, and in particular to a safety detection component for struts of external tower crane climbing frames. Background Technology

[0002] The climbing frame requires two diagonally placed support rods to connect the steel beams to the building walls.

[0003] The struts are the cornerstone of tower crane safety. To prevent accidents, construction workers need to regularly inspect the struts. If deformation is found, tower crane operation must be stopped immediately, and the struts replaced. If not addressed promptly, the deformation will increase with prolonged operation, potentially leading to an accident.

[0004] Because the inspection is conducted manually, it is impossible to monitor the condition of multiple support poles at all times. Furthermore, at night, the inspectors cannot clearly observe the condition of the support poles and cannot completely eliminate safety hazards. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a safety detection component for the climbing frame strut of an external tower crane, which can completely eliminate safety hazards.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A safety detection component for the climbing frame support rod of an external tower crane includes a support rod body, wherein a first through hole is provided on one side of the support rod body, and the straight line containing the central axis of the first through hole is collinear with the straight line containing the central axis of the support rod body.

[0022] The limiting annular plate is in contact with one end of the corresponding connecting rod;

[0023] The laser emitter portion passes through the corresponding limiting ring plate;

[0024] The laser receiver is located within the corresponding limiting ring plate.

[0025] In a preferred embodiment, the present invention can be further configured such that the laser receiver is a circular plate;

[0026] The straight line containing the central axis of the circular plate is collinear with the straight line containing the central axis of the laser source in the laser emitter.

[0027] In a preferred embodiment, the present invention can be further configured such that: both ends of the support rod body are provided with cover plates, and the cover plates are connected to the support rod body by bolts;

[0028] The cover plate will cover one end of the opening corresponding to the first through hole.

[0029] In a preferred embodiment, the present invention can be further configured such that a limiting block is fixedly provided on one side of the cover plate;

[0030] When the cover plate is installed on the support rod body, the limiting block is completely located in the first through hole, and one end of the limiting block is in contact with one end of the corresponding connecting rod.

[0031] In summary, this utility model has at least one of the following beneficial technical effects:

[0032] 1.

Detailed Implementation

[0039] The present invention will be further described in detail below with reference to the accompanying drawings.

[0040] Example:

[0041] Reference Figures 1-3 As shown, this utility model discloses a safety detection component for the support rod of an external tower crane climbing frame, including a support rod body 1. A first through hole 11 is provided on one side of the support rod body 1. The vertical cross-section of the first through hole 11 is circular. The first through hole 11 does not affect the strength of the support rod body 1 itself.

[0042] The straight line containing the central axis of the first through hole 11 is collinear with the straight line containing the central axis of the support rod body 1. Both ends of the support rod body 1 are provided with cover plates 5, which are bolted to the support rod body 1. The cover plates 5 cover the opening at one end corresponding to the first through hole 11.

[0043] A safety detection component 2 is installed inside the first through hole 11. When the support rod body 1 bends, the safety detection component will promptly notify the management personnel.

[0044] The security detection component 2 includes a laser emitter 21 and a laser receiver 22. The emission source in the laser emitter 21 is directly facing the laser receiver 22.

[0045] Two sets of fixing components 3 are provided on the first through hole 11. The two sets of fixing components 3 are respectively fixedly connected to the laser emitter 21 and the laser receiver 22.

[0046] The fixing assembly 3 includes an internally threaded tube 31 and a connecting rod 32. The internally threaded tube 31 is fixedly disposed at one end of the inner wall of the first through hole 11. An externally threaded tube 33 is fixedly sleeved on the outer circumferential surface of each connecting rod 32. The externally threaded tube 33 passes through the corresponding internally threaded tube 31 and is threadedly connected to the corresponding internally threaded tube 31. A laser emitter 21 is fixedly disposed at one end of the corresponding connecting rod 32. A laser receiver 22 is fixedly disposed at one end of the corresponding connecting rod 32. There is no obstruction between the laser receiver 22 and the laser emitter 21.

[0047] The laser receiver 22 is a circular plate, and the straight line containing the central axis of the circular plate is collinear with the straight line containing the central axis of the emission source in the laser emitter 21.

[0048] Two power supply units 23 and a wireless transmitter 24 are fixedly installed inside the first through hole 11. A laser transmitter 21 is electrically connected to the corresponding power supply unit 23, and a laser receiver 22 is electrically connected to the corresponding power supply unit 23. The wireless transmitter 24 is electrically connected to the laser receiver 22 and the corresponding power supply unit 23. The wireless transmitter 24 transmits signals to the corresponding wireless receiver for the administrator.

[0049] In this embodiment, the power supply unit 23, the wireless transmitter 24, and the wireless receiver are all existing technologies.

[0050] By setting a circular plate, the area of ​​the laser receiver 22 is increased. When the support rod body 1 undergoes slight deformation (without affecting use while ensuring safety), the laser emitted by the laser emitter 21 still shines on the circular plate.

[0051] Two limiting annular plates 4 are symmetrically arranged on the inner peripheral wall of the first through hole 11. The limiting annular plates 4 are in contact with one end of the corresponding connecting rod 32. The laser emitter 21 partially passes through the corresponding limiting annular plate 4. The laser receiver 22 is located inside the corresponding limiting annular plate 4.

[0052] A limiting block 6 is fixedly provided on one side of the cover plate 5. When the cover plate 5 is installed on the support rod body 1, the limiting block 6 is completely located in the first through hole 11, and one end of the limiting block 6 is in contact with one end of the corresponding connecting rod 32.

[0053] In this embodiment, the lifespan of the power supply unit 23 is sufficient to support the entire construction period.

[0054] In addition, when the strut body initially deforms, the laser receiver cannot receive the light emitted from the laser transmitter, the strut body can still be used, and the entire tower crane remains safe.

[0055] The embodiments described herein are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
