Technical Field
[0001] This invention relates to the field of construction safety products technology, and in particular to a quick-attachment device for construction safety belts. Background Technology
[0002] In building construction, after the main structure is completed, work such as interior masonry, plastering of adjacent walls, and pipe installation often involves heights exceeding 2 meters. Any work performed at a height of 2 meters or more above the reference plane where a fall is possible is considered work at height, requiring workers to wear safety belts. However, securing these belts presents a significant problem, especially when working on the exposed side of an exterior wall where the other side is suspended and there are no suitable locations to secure the belts. If the anchor points are not properly positioned, worker operation becomes inconvenient and the construction process is hampered. Summary of the Invention
[0003] To address the problem of inconvenient securing of safety belts in construction, this invention presents a quick-attachment device for building structural safety belts. It can be fixed to the crossbeams of the main building structure, is simple and convenient, and easy to operate.
[0004] The technical solution adopted in this invention is to design a quick-attachment device for construction safety belts, which is used to temporarily fix safety belts to the structural beams of buildings. The attachment device includes a bracket, which includes two frames located on both sides of the beam. One frame is provided with a telescopic rod, and the other frame is provided with an insertion hole into which the telescopic rod can be inserted. The bracket is connected to the safety belt.
[0005] In some embodiments, the telescopic rod is provided with an electromagnetic generating device that controls the magnetic strength of the telescopic rod, and the insertion hole has a magnetic attraction portion that can be attracted by magnetic force.
[0006] In some embodiments, the electromagnetic generating device is an electromagnetic coil rotating around the telescopic rod.
[0007] In some embodiments, each of the frames is provided with a traveling wheel supported on the crossbeam. The traveling wheel includes a wheel frame, and the traveling wheel is rotatably mounted on the wheel frame via a wheel axle. The wheel frame is provided with a pivot, which is rotatably connected to the frame. The pivot is fixedly connected to a connecting rod, and the connecting rod is connected to a support wheel located at the bottom of the crossbeam. The connecting rod is connected to the support via an elastic support member, and the connecting rod is inclined relative to the support towards the front of the support as it moves.
[0008] In some embodiments, the two frames are connected by a spacing adjustment device.
[0009] In some embodiments, the spacing adjustment device is a tension spring.
[0010] In some embodiments, the elastic support is a gas spring, and both ends of the gas spring are rotatably connected to the frame and the connecting rod, respectively.
[0011] In some embodiments, the bracket is provided with guide wheels located at the bottom of the crossbeam.
[0012] In some embodiments, telescopic rods are provided on both sides of the frame, and the telescopic rods are controlled by a telescopic mechanism to extend or retract toward the crossbeam.
[0013] In some embodiments, the telescopic rod has a friction end.
[0014] Compared with the prior art, the present invention has the following beneficial effects:
[0015] This invention utilizes brackets that can be fixed to the crossbeams of the main building structure, which greatly reduces the cost of safe construction, saves manpower and material resources, and solves the problem of workers wearing safety belts when working at heights, achieving a simple, quick, and safe result.
[0016] The linkage of the present invention automatically adjusts the orientation of the support by controlling the orientation of the traveling wheels, automatically controls the support to rise, and prevents it from detaching from the crossbeam when the support is being pulled forward, thus achieving an automatic correction function.

[0023] The following are specific embodiments of the present invention, and the technical solution of the present invention will be further described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments, and the following embodiments do not limit the invention covered by the claims. Furthermore, not all combinations of the features described in the embodiments are necessary for the inventive solution.
[0024] The principles and structure of the present invention will be described in detail below with reference to the accompanying drawings and embodiments.
[0025] Example 1
[0026] like Figure 1 As shown, a quick-attachment device for a construction safety belt 4 is used to temporarily fix the safety belt 4 to a structural beam 1 of a building. The attachment device includes a U-shaped frame bracket, which includes two frame bodies 2 located on either side of the beam 1. One frame body 2 is provided with a telescopic rod 3 that can extend and retract relative to the frame body, and the other frame body 2 is provided with an insertion hole 201 into which the telescopic rod 3 can be inserted. The bracket connects to the safety belt 4. In use, the frame end of the bracket faces upward, the beam 1 is positioned within the U-shaped frame of the bracket, the telescopic rod 3 is aligned with the screw hole of the beam 1, and then the screw passes through the screw hole and into the insertion hole 201, thereby fixing the bracket to the beam 1 and thus securing the safety belt 4.
[0027] The bolt holes on the building beam 1 refer to structural elements used for connection, hoisting, fixing, or suspension. These bolt holes are typically metal eyelets or threaded holes installed on the building beams or crossbeams 1, used to fix hooks, slings, ropes, or other equipment to support or suspend various equipment, pipes, lighting fixtures, or other devices.
[0028] These screw holes can be pre-designed threaded holes embedded inside the crossbeam 1, or they can be metal eye rings installed on the surface of the crossbeam 1 later using bolts, expansion bolts, or other methods. They provide convenient fixing points for hoisting, suspending, or supporting structures within buildings. These structural components play a vital role in hoisting and installation in construction, industry, and other fields, ensuring the safety and stability of equipment or installations.
[0029] An electromagnetic generating device is provided on the telescopic rod 3. The electromagnetic generating device controls the magnetic strength of the telescopic rod 3. For example, the electromagnetic generating device is an electromagnetic coil 301 that rotates around the telescopic rod 3. The telescopic rod 3 is an iron rod made of soft magnetic material. The magnetic strength of the telescopic rod 3 is controlled by controlling the current of the electromagnetic coil 301. The insertion hole 201 has a magnetic attraction part 202 that can be attracted by magnetic force. The magnetic attraction part 202 can be a ferromagnetic material provided at the bottom of the insertion hole 201. When the telescopic rod 3 is inserted into the insertion hole 201, the telescopic rod 3 generates magnetic force to attract the magnetic attraction part 202, thereby firmly fixing it in the insertion hole 201.
[0030] Example 2
[0031] like Figure 2 , 3 As shown in Figure 4, unlike the above embodiment, each of the frames is provided with a traveling wheel 5 supported on the crossbeam 1. That is, the support and the surface of the crossbeam 1 are supported by the traveling wheel 5, so that the support can be moved relative to the crossbeam 1 by the traction of the safety belt 4, thereby making it convenient to move the support to different positions and fix it.
[0032] The walking wheel 5 includes a wheel frame 6, which is equivalent to a wheel hub. The walking wheel 5 is rotatably mounted on the wheel frame 6 via a wheel axle. A rotating shaft 7 is fixed on the wheel frame 6. The rotating shaft 7 is rotatably connected to the frame 2, so that the rotating shaft 7 can rotate relative to the support. The frame 2 is simply provided with a shaft hole, and the rotating shaft 7 can slide through the shaft hole.
[0033] The rotating shaft 7 is fixedly connected to the connecting rod 8. The connecting rod 8 is connected to a support wheel 9 located at the bottom of the crossbeam 1. The connecting rod 8 is connected to the bracket through an elastic support member 10. The elastic support member 10 is a gas spring or a cylindrical spring. The two ends of the gas spring are rotatably connected to the frame and the connecting rod 8, respectively. The connecting rod 8 is inclined relative to the bracket in the forward direction of the bracket's movement.
[0034] Since the connecting rod 8 is fixedly connected to the rotating shaft 7, when the connecting rod 8 rotates relative to the bracket, i.e., the tilt angle of the connecting rod 8 relative to the bracket changes, the relative movement direction of the traveling wheel 5 also changes, i.e., it tilts relative to the horizontal direction. For example, when the bracket moves downward relative to the crossbeam 1, because the connecting rod 8 and the bracket are supported by the elastic support member 10, when the bracket moves downward, the elastic support member 10 will cause the connecting rod 8 to move away from the bracket, i.e., the connecting rod 8 will move towards the front of the bracket, making the tilt angle of the connecting rod 8 relative to the bracket larger, thereby causing the traveling wheel 5 to tilt upward relative to the bracket, thus pulling the bracket forward. This causes the support to move upward relative to the crossbeam 1. As the support moves upward, the crossbeam 1 presses down on the support wheel 9, causing the connecting rod 8 to move toward the support. This reduces the angle of inclination of the connecting rod 8 relative to the support, which in turn reduces the upward angle of the traveling wheel 5 until the traveling wheel 5 is horizontal. Under the traction of the safety belt 4, the support moves forward horizontally relative to the crossbeam 1, preventing the support from detaching from the crossbeam 1 and falling. In other words, the connecting rod 8 automatically and smoothly adjusts the orientation of the support by controlling the orientation of the traveling wheel 5, automatically controlling the support to rise and preventing it from detaching from the crossbeam 1 when being pulled forward, thus achieving an automatic correction function.
[0035] The two frame bodies 2 are connected by a spacing adjustment device, which can be a tension spring 11. The tension spring 11 can be set in two mutually sliding and nested cylinders 12. The two cylinders 12 are respectively fixedly connected to the frame bodies 2 on both sides to provide a guiding effect for extension and retraction, so that the support and the crossbeam 1 support have a certain clamping force.
[0036] A guide wheel 13 located at the bottom of the crossbeam 1 can also be provided on the bracket to provide a guiding effect between the bottom of the crossbeam 1 and the bracket.
[0037] Telescopic rods 3 facing the crossbeam 1 can be provided on both sides of the frame 2. The telescopic rods 3 are controlled by a telescopic mechanism to extend and retract toward the crossbeam 1. The telescopic mechanism can be an electric telescopic mechanism such as a solenoid valve 14, so as to facilitate simultaneous insertion into the reserved screw holes of the crossbeam 1 from both sides.
[0038] The telescopic rod 3 can be provided with an end head 15 with a large friction surface, so that the end head 15 can be clamped on the surface of the crossbeam 1 by the extension and retraction of the telescopic rod 3, which can also fix the seat belt 4 without having to be inserted into the screw hole.
[0039] Although this document uses a number of technical terms, the possibility of using other terms is not excluded. These terms are used merely for the convenience of describing and explaining the essence of the invention; interpreting them as any additional limitation would contradict the spirit of the invention. The order of actions, steps, etc., in the apparatus and methods shown in the specification and drawings can be implemented in any order unless otherwise expressly specified, and provided that the output of a preceding process is not used in a subsequent process. Similar sequential terms used for descriptive convenience (e.g., "firstly," "next," "secondly," "again," "then," etc.) do not imply that the actions must be performed in such an order.
[0040] Those skilled in the art will understand that all directional references (e.g., above, below, up, down, down, top, bottom, left, right, vertical, horizontal, etc.) are used descriptively in the drawings to aid the reader's understanding and do not imply (e.g., a limitation on the scope of the invention as defined by the appended claims) a limitation on the location, orientation, or use of the invention, but are merely for the purpose of facilitating the description of this application and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a particular orientation or be constructed and operated in a particular orientation. The directional terms "inside" and "outside" refer to inside or outside relative to the outline of the respective component itself.
[0041] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.
[0042] Additionally, some vague terms (e.g., substantially, certain, generally, etc.) may refer to slight inaccuracies or minor deviations in conditions, quantities, values, or dimensions, some of which are within manufacturing tolerances or limits. It should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components; unless otherwise stated, these terms have no special meaning and therefore should not be construed as limiting the scope of protection of this application.
[0043] The specific embodiments described herein are merely illustrative examples illustrating the spirit of the invention. Those skilled in the art can make various modifications or additions to the described embodiments or use similar methods to substitute them, without departing from the spirit of the invention or exceeding the scope defined by the appended claims.
