Description

Technical Field

[0001] The invention belongs to the technical field of safety devices, and in particular is an alarm-enabled intelligent safety belt device for large-span assembled construction. Background Art

[0002] Large-span prefabricated construction refers to the use of prefabricated components for assembly in construction projects to achieve structural design and construction with larger spans. This construction method usually involves large bridges, gymnasiums, exhibition centers and other buildings that require large spaces and large spans.

[0003] During large-span prefabricated construction, construction workers need to wear safety belts, and most of the existing alarm smart safety belts are generally equipped with tension sensors at the hooks and fixed points. When the construction workers fall or the safety belts are accidentally pulled, the sensors can detect the change in tension in real time and transmit the data to the control unit, thereby triggering the alarm mechanism in time. However, when the construction workers bend over or pick up some tools, the tension may change, which may cause the alarm mechanism to be triggered by mistake. After the alarm is triggered, the circuit of most of the existing smart safety belts may enter a protection or locking state, which is inconvenient to reset, resulting in the construction workers and on-site personnel suspending their work. If the reset operation is complicated and time-consuming, each such situation will waste a lot of time. For some construction links that require continuous operation, such as the hoisting and splicing of large prefabricated components, frequent failure to quickly reset will seriously affect the construction progress, thereby increasing the overall construction period. Therefore, an alarm-enabled smart safety belt device for large-span prefabricated construction is proposed to solve the problems raised in the background technology. Summary of the invention

DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] like Figures 1 to 9As shown, the present invention provides an alarm-enabled intelligent safety belt device for large-span assembled construction, comprising a safety belt body 1, a support box 2 is fixedly connected to one side of the safety belt body 1, an outer box 3 is clamped inside the support box 2, a motor 4 is fixedly connected inside the outer box 3, and a transmission assembly 5 is movably connected inside the outer box 3;

[0037] The transmission assembly 5 includes a first gear 51, a second gear 52 and a third gear 53. The inner wall of the first gear 51 is provided with two first arc grooves 54 in an annular manner. The inner wall of the third gear 53 is provided with a vertical groove 55, a second arc groove 56 and a third arc groove 57 in an annular manner.

[0038] The first gear 51 is movably connected to the first round rod 6, the third gear 53 is movably connected to the moving assembly 7, the support box 2 is movably connected to the clamping assembly 8, the outer box 3 is provided with a motion sensor 9, and the outer side of the outer box 3 is fixedly connected to a buzzer alarm 11;

[0039] The clamping assembly 8 includes a clamping plate 81 , and first limit plates 82 are movably connected to both sides of the interior of the support box 2 , and an inclined block 83 is fixedly connected to the top of the first limit plate 82 .

[0040] The above scheme is adopted: the second gear 52 and the third gear 53 are half smooth and half toothed, so that the second gear 52 and the third gear 53 can only drive the first gear 51 to rotate 180 degrees every time they rotate one circle. After the second round rod 71 moves up and down once, the third gear 53 can be driven to rotate counterclockwise for one circle through the cooperation between the vertical groove 55, the second arc groove 56 and the third arc groove 57, so that the teeth of the third gear 53 are engaged with the first gear 51, and drive the first gear 51 to rotate 180 degrees clockwise. After the first gear 51 rotates, the first round rod 6 slides upward along the trajectory of the first arc groove 54, so that the first round rod 6 releases the pressure on the button 10, thereby disconnecting the circuit inside the outer box 3, and then stopping the buzzer alarm 11, thereby facilitating the resetting of the device, thereby improving the overall convenience and practicality of the device.

[0041] like Figure 2 , Figure 3 and Fig. 9As shown, the opposite sides of the two first limit plates 82 are fixedly connected with the second limit plate 84, and the end of the second limit plate 84 close to the clamping plate 81 is provided with an inclined groove 85, and the bottom end of the second limit plate 84 is fixedly connected with the second elastic piece 86, and the second limit plate 84 is elastically connected to the support box 2 through the second elastic piece 86, and the opposite ends of the two inclined blocks 83 are inclined, and the two ends of the support box 2 are threadedly connected with the bolt assembly 12, and the bottom end of the inclined block 83 is provided with an internal thread compatible with the bolt assembly 12, and the two ends of the bottom of the clamping plate 81 are provided with a protrusion that is movably clamped in the inclined groove 85, and the two inclined grooves 85 are in opposite directions. A gasket 87 is provided on the side of the clamping plate 81 close to the outer box 3, and the gasket 87 is made of rubber material. In the initial state, the gasket 87 abuts against the side wall of the outer box 3.

[0042] The above scheme is adopted: the top of the inclined block 83 is inclined, and its function is that when the outer box 3 needs to be reinstalled into the supporting box 2, at this time, the bottom end of the outer box 3 is abutted against the inclined surface of the inclined block 83, thereby squeezing the two inclined blocks 83 to move in opposite directions. While the inclined block 83 moves, the clamping plate 81 moves in the direction away from the outer box 3 under the action of external force. Then, the outer box 3 is directly inserted into the supporting box 2 until the outer box 3 releases the abutment against the inclined block 83. At this time, through the design of the second elastic piece 86, the first limiting plate 82 drives the inclined block 83 to return to its original position under the action of the elastic force of the second elastic piece 86, so that the inclined block 83 abuts and limits the top of the outer box 3. While the inclined block 83 is reset, the clamping plate 81 is driven to reset by external force, and then the clamping plate 81 drives the gasket 87 to abut against the side wall of the outer box 3, thereby clamping and fixing the outer box 3;

[0043] The gasket 87 is made of rubber material. Its function is that rubber material has good friction and resistance. Therefore, when the gasket 87 abuts against the side wall of the outer box 3, the friction between the two will be increased, thereby improving the clamping and fixing effect of the outer box 3, preventing the outer box 3 from sliding or displacing inside the support box 2, thereby ensuring that the outer box 3 is stably fixed inside the support box 2.

[0044] like Figures 3 to 6As shown, the output shaft end of the motor 4 is fixedly connected to the second gear 52, and the second gear 52 and the third gear 53 both have teeth on one side and are smooth on the other side. The second gear 52 and the third gear 53 are symmetrically arranged on both sides of the first gear 51, and the arc of the first arc groove 54 is one hundred and eighty degrees. The top of the first round rod 6 is provided with a connecting column that is movably engaged with the inside of the first arc groove 54, and the bottom end of the first round rod 6 is provided with a square plate. The inner wall of the outer box 3 is provided with a square groove for circumferentially limiting the square plate at the bottom of the first round rod 6. The interior of the outer box 3 is provided with a button 10 located directly below the first round rod 6. After the first gear 51 rotates, it drives the connecting column on the first round rod 6 to slide along the trajectory of the first arc groove 54 and moves the first round rod 6 downward. After the first round rod 6 moves downward, it abuts against the button 10.

[0045] Adopt the above scheme: Figure 5 It can be seen that the second gear 52 and the third gear 53 are symmetrically arranged, and their function is that when the second gear 52 rotates clockwise for one circle and drives the first gear 51 to rotate counterclockwise by one hundred and eighty degrees, at this time, the smooth surface of the third gear 53 contacts the first gear 51, so that when the second gear 52 rotates, the third gear 53 will not be driven to rotate through the first gear 51. When the second gear 52 rotates for one circle to reset, then, when the third gear 53 rotates counterclockwise for one circle, the smooth surface of the second gear 52 contacts the first gear 51, so that when the third gear 53 rotates, it will only drive the first gear 51 to reverse and reset, thereby ensuring the normal operation of the device.

[0046] like Figures 4 to 8 As shown, the upper and lower ends of the vertical slot 55 are respectively connected with the second arc slot 56 and the third arc slot 57, and the end of the second arc slot 56 away from the vertical slot 55 is connected with the end of the third arc slot 57 away from the vertical slot 55. The curvature of the second arc slot 56 is 260 degrees, and the curvature of the third arc slot 57 is 100 degrees. The moving component 7 includes a second round rod 71, and the outer wall of the second round rod 71 is provided with a round block. In the initial state, the round block is movably connected to the top of the vertical slot 55. The bottom end of the second round rod 71 is fixedly connected to the limiting block 72, and the inner wall of the outer box 3 is provided with a sliding groove for limiting the limiting block 72. The top end of the second round rod 71 passes through the outer wall of the outer box 3 and is flush with the top of the outer box 3. The top of the limiting block 72 is provided with an anti-slip groove, and the bottom of the limiting block 72 is fixedly connected with a first elastic sheet 73, which is fixedly connected to the outer box 3. The first elastic sheet 73 is used to squeeze the limiting block 72 and keep the limiting block 72 moving upward.

[0047] The above scheme is adopted: when the operator releases the second round rod 71, the limit block 72 will be reset under the action of the elastic force of the first spring piece 73, and when the second round rod 71 moves up, the round block slides to the inside of the third arc groove 57 through the second arc groove 56. Therefore, after the second round rod 71 moves up, it drives the round block to slide along the trajectory of the third arc groove 57, thereby causing the third gear 53 to continue to rotate counterclockwise by 100 degrees. When the second round rod 71 is completely reset, the round block on its outer wall slides back to the top of the vertical groove 55 through the third arc groove 57. At the same time, after the second round rod 71 moves back and forth once, through the cooperation between the vertical groove 55, the second arc groove 56 and the third arc groove 57, it just drives the third gear 53 to rotate counterclockwise for one circle, thereby facilitating the reset of the third gear 53 and facilitating the next use.

[0048] The working principle and use process of the present invention are as follows: the construction worker wears the safety belt body 1 on the body. When the construction worker performs large-span assembly construction work, the motion sensor 9 monitors the body movement of the construction worker. When the operator's body tilt angle is abnormal, or the acceleration suddenly increases, the motion sensor 9 converts the abnormal signal into an electrical signal and transmits it to the information terminal. Subsequently, the information terminal issues a start command to the motor 4, thereby driving the second gear 52 to rotate clockwise for one circle through the motor 4.

[0049] When the second gear 52 rotates, the teeth on it will mesh with the first gear 51, thereby driving the first gear 51 to rotate 180 degrees counterclockwise, and then the connecting column on the first round rod 6 slides along the trajectory of the first arc groove 54. Since the inner wall of the outer box 3 is provided with a square groove for limiting the first round rod 6, the connecting column can only drive the first round rod 6 to move downward, and then the first round rod 6 abuts against the button 10. After the button 10 is pressed by the first round rod 6, the circuit inside the outer box 3 is closed, and the signal of the closed circuit is transmitted to the buzzer alarm 11. Subsequently, the buzzer alarm 11 sounds an alarm, thereby reminding the surrounding people;

[0050] When the crisis is resolved, the construction worker presses the second round rod 71, so that the second round rod 71 drives the limit block 72 downward, and then the round block on the outer wall of the second round rod 71 moves downward along the track of the vertical groove 55, and then slides to the inside of the second arc groove 56 through the vertical groove 55, and drives the third gear 53 to rotate 260 degrees along the track of the second arc groove 56. While the third gear 53 rotates, its teeth mesh with the first gear 51, thereby driving the first gear 51 to rotate 180 degrees clockwise, and then the first round rod 6 moves up along the track of the first arc groove 54, releasing the contact with the button 10, and then the circuit inside the outer box 3 is disconnected, and the disconnection signal is transmitted to the buzzer alarm 11, so that the buzzer alarm 11 stops the alarm;

[0051] When the motion sensor 9 needs to be inspected or maintained, the construction personnel rotate the bolt assembly 12 to disengage the bolt assembly 12 from the inside of the inclined block 83, thereby releasing the fixation of the inclined block 83 to the support box 2. Subsequently, the two inclined blocks 83 are pulled to the sides respectively, so that the bottom end of the inclined block 83 is released from the abutment against the top of the outer box 3. While the inclined block 83 moves, the second limiting plate 84 is driven to move in the same direction through the first limiting plate 82, so that the protrusion at the bottom of the clamping plate 81 slides along the trajectory of the inclined groove 85, and the clamping plate 81 drives the gasket 87 to move away from the outer box 3, thereby releasing the clamping and fixation of the outer box 3, and then facilitating the removal of the outer box 3 from the inside of the support box 2, so as to facilitate the subsequent maintenance and inspection of the motion sensor 9.
