Description

Technical Field

[0001] This utility model mainly relates to the technical field of descent devices, specifically a high-altitude construction descent protection device. Background Technology

[0002] A high-altitude construction descent device is a safety device used for high-altitude escape or rescue. It allows people to descend slowly along a rope. The key to the operation of the descent device is the slow descent. The planetary gear reduction mechanism inside the main unit is driven by the descent rope, which generates friction with the friction blocks in the friction hub to ensure the user's safe descent to the ground. In the fields of high-rise building maintenance and emergency rescue, descent devices play a vital role. However, existing high-altitude construction descent devices only use one set of descent devices. When the descent device is used multiple times, it is prone to failure, which would be very dangerous for workers to use if it were to fail.

[0003] According to application number 202121064511.1, a high-altitude construction descent device is provided, including a shell, a gear groove is provided on the inner side of the shell, a safety belt mounting plate is installed on the front wall of the shell, a safety belt mounting hole is provided inside the safety belt mounting plate, a connecting plate is installed on the front wall of the safety belt mounting plate, a plurality of fixing nuts are installed on the front wall of the connecting plate, a central shaft is installed inside the connecting plate, and handles are installed on both ends of the central shaft.

[0004] The aforementioned document improves the quality and practicality of the device by strengthening the limit on the rope; and by fixing the connecting plate to the shell with multiple fixing nuts, the connection inside the descent device is more stable. However, it still only adopts one set of descent measures, lacks emergency protection measures when the device malfunctions, and the maximum load capacity of the device is relatively low. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a high-altitude construction descent protection device to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A high-altitude construction descent protection device includes a rotating disk, a first internal gear disk and a second internal gear disk disposed on both sides of the rotating disk, a first escapement disk disposed on the side of the first internal gear disk away from the rotating disk, a second escapement disk disposed on the side of the second internal gear disk away from the rotating disk, four escapement blocks disposed at the upper and lower ends of the first escapement disk and the second escapement disk respectively, a connecting wheel disposed in the middle of the rotating disk, a reset rod disposed inside the connecting wheel, and two housings disposed on both sides of the connecting wheel.

[0008] Preferably, the rotating disk includes driven gears arranged in a triangular pattern on both sides, a pressure-resistant rope sleeved in the middle of the rotating disk, and a rope groove at the bottom of the housing.

[0009] Preferably, the middle part of the first escapement plate is fixedly connected to the connecting wheel, and includes a first gear disposed on the side near the rotating plate.

[0010] Preferably, the second escapement disc includes a second gear located near the rotating disc and a hollow tooth groove located in the middle of the second escapement disc and the second gear.

[0011] Preferably, the escapement block has a hollow circle inside, including a positioning post located at the upper and lower ends of the first internal gear disk and the second internal gear disk, a hairspring sleeved on the outer ring of the positioning post, and a rotating post located at the top of the escapement block and rotatably connected to the inner wall of the housing.

[0012] Preferably, the two ends of the connecting wheel are rotatably connected to the inner walls of the two housings, including a hollow annular groove disposed in the inner ring of the hollow tooth groove, and a deflection block disposed in the hollow annular groove in an annular matrix.

[0013] Preferably, the reset rod is rotatably disposed within the hollow annular groove, and includes a rope loop wound around the reset rod and connected to the front and rear ends of the deflection block, and a knob disposed on the outside of the housing and fixedly connected to the other end of the reset rod.

[0014] In summary, this technical solution has the following main advantages:

[0015] This invention achieves a dual descent mechanism by setting two sets of slow-descent structures on both sides of the device, one for backup and one for use. Under normal circumstances, one escapement plate and its related components are responsible for the slow-descent operation; when a fault occurs, the other escapement plate and its related components are connected in an emergency by the centrifugal rotation of the deflector block to continue providing the slow-descent function, thereby greatly improving the safety and reliability of the device.

[0016] The reset lever and rope loop design in the device allows users to reset all deflector blocks by rotating the knob after the deflector blocks are thrown out, ensuring that the device can work normally after troubleshooting. In addition, by actively connecting the structure on the other escapement plate side to operation, the carrying capacity of the device can be improved. This design improves the flexibility of the device and its ability to adapt to different working environments. Attached Figure Description

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0024] Example

[0025] Please refer to the attached document carefully. Figure 1 , 2 As shown in Figures 3 and 4, a high-altitude construction descent protection device includes a rotating disk 10, a first internal gear disk 11 and a second internal gear disk 12 disposed on both sides of the rotating disk 10, a first escapement disk 13 disposed on the side of the first internal gear disk 11 away from the rotating disk 10, a second escapement disk 14 disposed on the side of the second internal gear disk 12 away from the rotating disk 10, four escapement blocks 15 disposed at the upper and lower ends of the first escapement disk 13 and the second escapement disk 14 respectively, a connecting wheel 16 disposed in the middle of the rotating disk 10, a reset rod 17 disposed inside the connecting wheel 16, and two housings 18 disposed on both sides of the connecting wheel 16. The rotating disk 10 includes driven gears 101 arranged in a triangular pattern on both sides, a pressure-resistant rope 102 sleeved in the middle of the rotating disk 10, and a rope groove 103 at the bottom of the housing 18; the middle of the first escapement disk 13 is fixedly connected to the connecting wheel 16, and includes a first gear 131 located near the rotating disk 10; the escapement block 15 has a hollow circle inside, including positioning pins 151 located at the upper and lower ends of the first internal gear disk 11 and the second internal gear disk 12, a hairspring 152 sleeved on the outer ring of the positioning pins 151, and a rotating pin 153 located at the top of the escapement block 15 and rotatably connected to the inner wall of the housing 18.

[0026] As described above, during normal use, one end of the pressure-resistant rope 102 is connected to the rope loop, and the other end is connected to the safety belt. The two ends of the pressure-resistant rope 102 enter and exit from the two sets of rope grooves 103 respectively. When the safety belt is pulled, the pressure-resistant rope 102 continuously passes through the rotating disk 10, driving the rotating disk 10 to rotate. The rotating disk 10 drives the first escapement disk 13 to rotate through the connecting wheel 16, which in turn drives the first gear 131 to rotate synchronously, and the three driven gears 101 arranged in a triangle on the same side to rotate in the first internal gear disk 11. At the same time, the three driven gears 101 mesh with the first gear 131 in the middle to form a gear reduction structure. When the first escapement disk 13 rotates, the escape block 15, under the elastic force of the hairspring 152 and the alternating push of the first escapement disk 13, restricts the rotation speed of the first escapement disk 13, thereby acting in the opposite direction on the rotating disk 10 to make it rotate slowly, realizing the basic function of the entire device's descent device.

[0027] Please refer to the attached document carefully. Figure 3 , 4 As shown in Figure 5, the second escapement plate 14 includes a second gear 141 located near the rotating plate 10, and a hollow tooth groove 142 located in the middle of the second escapement plate 14 and the second gear 141; the connecting wheel 16 is rotatably connected at both ends to the inner walls of the two housings 18, including a hollow annular groove 161 located in the inner ring of the hollow tooth groove 142, and a deflecting block 162 arranged in an annular matrix within the hollow annular groove 161; the reset rod 17 is rotatably located within the hollow annular groove 161, including a rope loop 171 wound around the reset rod 17 and connected to the front and rear ends of the deflecting block 162, and a knob 172 located on the outside of the housing 18 and fixedly connected to the other end of the reset rod 17.

[0028] Under normal circumstances, only the components on one side of the first internal gear disk 11 operate. With the second escapement disk 14 supported by the three driven gears 101 on the same side, the hollow tooth groove 142 in the middle of the second gear 141 does not contact the connecting wheel 16. The deflector block 162 is narrower at the front and wider at the back, with a right-angled block at one end. When rotated to a certain angle, the right-angled block will lock onto the surface of the hollow annular groove 161. When the components on one side of the first internal gear disk 11 malfunction and cannot operate normally, the rotating disk 10 and the connecting wheel 16 will rotate at high speed during use. At this time, the deflector block 162 inside the hollow annular groove 161 will rotate and pop out under centrifugal force, locking inside the hollow tooth groove 142. When the meshing structure is formed, the second escapement disc 14 and the second gear 141 are connected to the connecting wheel 16. The deceleration device structure on the other side of the rotating disc 10 intervenes in emergency operation, realizing the backup protection capability of this device. The surface of the hollow ring groove 161 has a through groove for the rope ring 171. After the deflection block 162 is centrifugally thrown out, the reset rod 17 can be rotated by rotating the knob 172, and all the deflection blocks 162 can be reset through the rope ring 171. Alternatively, when there is no fault in the components on the side of the first internal gear disc 11, the knob 172 can be rotated in the opposite direction to pull the deflection block 162 out, actively connecting the structure where the second internal gear disc 12 is located to operation, which can multiply the carrying capacity of this device.

[0029] The above embodiments are only for illustrating the technical concept of this utility model and should not be construed as limiting the scope of protection of this utility model. Any modifications made to the technical solution based on the technical concept proposed by this utility model shall fall within the scope of protection of this utility model.
