[0002] The main functions of a climber include rock climbing, rappelling, caving, stream rappelling, rescue, aerial work, engineering protection and development training. For aerial work, an electric climber is used. After the object is moved to the position, it needs to be decelerated to avoid the object falling due to the object rising too fast. At present, the deceleration effect of the electric climber is poor. It is impossible to consider factors such as the weight of the object or the climbing height of the object to control the deceleration intensity, resulting in instability of the object after it stops rising, and it falls from the climber, or the position accuracy of the object is poor. This phenomenon has become a problem that people in this field need to solve urgently. Summary of the invention

[0005] The present invention further illustrates that a weight sensor is provided inside the heavy-load high-speed climber, a weight sensing module is provided inside the weight sensor, the weight sensing module is electrically connected to the electric motor, and the weight sensing module is used to sense the weight of an object through the weight sensor and control the number of rotations of the electric motor according to the weight of the object.

[0006] The present invention further illustrates that the heavy-load high-speed climber includes a hydraulic control system, which includes a height recognition module, a wind force measurement module and a hydraulic control module; the height recognition module, the wind force measurement module and the hydraulic control module are electrically connected to each other, the height recognition module is used to identify the climbing height of the object, the wind force measurement module is used to calculate the wind force according to the climbing height of the object, and the hydraulic control module is used to calculate the hydraulic size of the liquid pump according to various parameters, and control the liquid pump to operate according to the hydraulic size.

[0007] The present invention further illustrates that the first hydraulic pressure value measured by the hydraulic control module is: Ep = m*g*h, Ep is the gravitational potential energy of the object, m is the weight of the object, g is the gravitational acceleration of the object, h is the climbing height of the object, F1 is the first hydraulic pressure value of the liquid pump, and ... max is the gravitational potential energy received by the object when the climber moves to the highest position, F max is the maximum hydraulic pressure of the liquid pump; that is, the higher the object climbs, the greater the gravitational potential energy it is subjected to, and thus the greater the hydraulic pressure of the liquid pump.

[0011] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: the present invention adopts a heavy-load high-speed climber, which is convenient for quickly lifting objects, and when the object stops at the position, it is decelerated, and the threaded rod drives the deceleration plate to rotate, and the deceleration plate squeezes the liquid in the deceleration chamber. The liquid applies resistance to the deceleration plate, thereby decelerating the output shaft, so that the heavy object can stop steadily after rising to the position, thereby improving the climbing stability. The liquid flows through the holes, which can relatively reduce the deceleration intensity, avoiding the phenomenon that the object cannot be accurately moved to the specified position due to excessive resistance, and the conical holes can both reduce the deceleration intensity and avoid the reduced intensity being too low to affect the deceleration effect. When the speed brake rotates, the sealing plate and the opening and closing plate squeeze the liquid on the right side of the speed brake, thereby increasing the resistance of the liquid to the speed brake and greatly improving the buffering strength. The liquid flows back and forth in the hole, further improving the deceleration effect, and having an excellent deceleration effect on the climbing of objects. By combining the speed brake and the resistance plate, when the speed brake rotates, the resistance between the two and the liquid increases, and the deceleration effect is enhanced. For heavier objects, the resistance of the speed brake and the resistance plate is increased, and vice versa, the resistance is reduced. On the one hand, the buffering effect can be further enhanced, and on the other hand, the poor accuracy of the moving position of the object caused by excessive resistance can be avoided, which affects the climbing process of the object.

[0012] By setting up a hydraulic control system, the liquid pressure in the deceleration chamber is intelligently adjusted, and the liquid density is controlled, so that the resistance encountered by the deceleration plate when rotating is increased, the deceleration effect can be enhanced, and the object can be prevented from shaking and falling due to the inability to decelerate in time, thereby ensuring the stability of the object when it stops. The lower the object climbs, the lower the liquid density in the deceleration chamber. At this time, the speed at which the object stops can be relatively accelerated, thereby accelerating the object's climbing efficiency. At the same time, the liquid pressure is optimized according to the wind force and gravity potential energy, and the liquid density is optimized, which can improve the climbing stability and avoid the phenomenon that the object cannot be moved into place.

DETAILED DESCRIPTION

[0025] The following is a further non-limiting detailed description of the technical solution of the present invention in conjunction with the preferred embodiments and the accompanying drawings. 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.

[0026] See also Figure 1-Figure 10 The present invention provides a technical solution: a heavy-load high-speed climber based on intelligent deceleration, comprising a housing 1, a winch 2 and a traction wheel 3 are installed on the left bearing of the housing 1, the traction wheel 3 is located above the winch 2, and a climbing rope 4 is wound between the traction wheel 3 and the winch 2;

[0027] The upper end of the climbing rope 4 is fixed at the ascending position, and the lower end is fixed to the object. The inner wall of the housing 1 is fixed with a motor 5. The output end of the motor 5 is fixedly connected with an output shaft 51. The output shaft 51 is fixed to the winch 2. The outer ring bearing of the output shaft 51 is installed with a deceleration chamber 6. The deceleration chamber 6 includes two sealing disks 61, two opening and closing plates 62, an electric motor 63, a telescopic joint 631, a threaded rod 632 and a deceleration plate 64.

[0028] The two sealing disks 61 are arranged opposite to each other and are fixedly mounted on the inner wall of the deceleration chamber 6, and the inner sides of the two sealing disks 61 are provided with sliding grooves. The two opening and closing plates 62 are respectively slidably connected in the sliding grooves of the two sealing disks 61, and the inner sides are fitted with each other. A spring 65 is fixed between the opening and closing plates 62 and the inner wall of the sealing disk 61. The interior of the output shaft 51 is hollow, and the electric motor 63 is fixedly mounted on the inner wall of the output shaft 51. The telescopic joint 631 is fixedly connected to the output end of the electric motor 63. A threaded hole is provided on the surface of the output shaft 51, and the threaded rod 632 is threadedly connected in the threaded hole. The lower end of the threaded rod 632 is fixed to the telescopic joint 631, and the upper end The bearing of the deceleration plate 64 is connected, and a hole 641 is provided on the surface of the deceleration plate 64. The deceleration chamber 6 is fixedly mounted on the inner wall of the housing 1, and the interior of the deceleration chamber 6 is filled with liquid, and the deceleration chamber 6 is connected to the external liquid pump pipeline. An extrusion block 642 is fixed on the right side of the deceleration plate 64, and two resistance plates 66 are fixed on the outside of the output shaft 51. Two sliding holes are provided at the bottom of the deceleration plate 64, and the resistance plates 66 are slidably connected in the sliding holes. The hole 641 is conical, and the inner side of the opening and closing plate 62 is arc-shaped. The extrusion block 642 is conical, and the diameter of the left side is equal to the width of the deceleration plate 64, and the right end of the extrusion block 642 is spherical.

[0029] The object is hung on the lower end of the climbing rope 4, and the upper end of the climbing rope 4 is fixed at a high place. Then the motor 5 runs, driving the output shaft 51 to rotate, the output shaft 51 drives the winch 2 to rotate, the winch 2 drives the climbing rope 4 to pull the object, and at the same time the traction wheel 3 rotates through the climbing rope 4 to pull the climbing rope 4, thereby driving the object to rise through the heavy-load high-speed climber. After the object rises to a designated position at a high place, the motor 5 is turned off, and at the same time the internal structure of the deceleration chamber 6 decelerates the output shaft 51, and the output shaft 51 drives the deceleration plate 64 to rotate through the threaded rod 632, and the deceleration plate 64 squeezes the liquid in the deceleration chamber 6, and the liquid applies resistance to the deceleration plate 64, thereby decelerating the output shaft 51, so that the heavy object can stop steadily after rising to the position, thereby improving the stability of climbing;

[0030] The liquid is pushed by the deceleration plate 64, and the liquid flows through the hole 641, which can relatively reduce the deceleration strength, and avoid the phenomenon that the object cannot be accurately moved to the specified position due to excessive resistance. The conical hole 641 can not only reduce the deceleration strength, but also avoid the reduced strength being too low to affect the deceleration effect. When the deceleration plate 64 rotates to the bottom of the opening and closing plate 62, the outer end of the extrusion block 642 contacts the inner side of the opening and closing plate 62 and pushes the extrusion block 642 to open it. The conical extrusion block 642 can make the extrusion block 642 fully open, and then the deceleration plate 64 can smoothly pass through the opening and closing plate 62, ensuring a continuous and effective buffering effect.

[0031] At the same time, when the deceleration plate 64 rotates, the liquid on the right side of the deceleration plate 64 is squeezed through the sealing plate 61 and the opening and closing plate 62, so that the resistance of the liquid to the deceleration plate 64 is strengthened, and the buffering strength is greatly improved. The liquid flows back and forth in the hole 641, so that the deceleration effect is further improved, and the deceleration effect on the climbing object is excellent.

[0032] A weight sensor is provided inside the heavy-load high-speed climber, and a weight sensing module is provided inside the weight sensor. The weight sensing module is electrically connected to the electric motor 63. The weight sensing module is used to sense the weight of an object through the weight sensor, and control the number of rotations of the electric motor 63 according to the weight of the object.

[0033] The heavier the object, the more turns the electric motor 63 rotates. After the electric motor 63 rotates, the threaded rod 632 is driven to rotate through the telescopic joint 631, so that it moves upward through the threaded hole. The threaded rod 632 drives the deceleration plate 64 to move upward. At the same time, the resistance plate 66 slides along the inner wall of the sliding hole, so that the exposed surface of the resistance plate 66 is increased. The deceleration plate 64 is combined with the resistance plate 66, so that when the deceleration plate 64 rotates, the resistance generated between the two and the liquid increases, and the deceleration effect is enhanced.

[0034] The number of revolutions of the electric motor 63 is controlled by the weight of the object, thereby controlling the exposed area of ​​the resistance plate 66, causing the resistance to change. For heavier objects, the resistance to the deceleration plate 64 and the resistance plate 66 is increased, and vice versa. On the one hand, the buffering effect can be further enhanced, and on the other hand, poor accuracy of the object's moving position caused by excessive resistance can be avoided, which affects the object's climbing process.

[0035] The heavy-load high-speed climber includes a hydraulic control system, which includes a height recognition module, a wind force measurement module and a hydraulic control module;

[0036] The height recognition module, the wind force measurement module and the hydraulic control module are electrically connected to each other. The height recognition module is used to identify the climbing height of the object, the wind force measurement module is used to calculate the wind force according to the climbing height of the object, and the hydraulic control module is used to calculate the hydraulic pressure of the liquid pump according to various parameters and control the liquid pump to operate according to the hydraulic pressure.

[0037] The first hydraulic pressure value measured by the hydraulic control module is:

[0038] Ep is the gravitational potential energy of the object, m is the weight of the object, g is the gravitational acceleration of the object, h is the climbing height of the object, F1 is the first hydraulic pressure value of the liquid pump, and ... max is the gravitational potential energy received by the object when the climber moves to the highest position, F max is the maximum hydraulic pressure of the liquid pump;

[0039] That is, the higher the object climbs, the greater the gravitational potential energy it is subjected to, and thus the greater the hydraulic pressure of the pump;

[0040] The higher the object climbs, the greater the hydraulic pressure of the liquid pump, so that the greater the pressure applied to the liquid in the deceleration chamber 6. At this time, the density of the liquid increases, so that the resistance encountered by the deceleration plate 64 when it rotates increases, which can enhance the deceleration effect, prevent the object from shaking and falling due to failure to decelerate in time, and ensure the stability of the object when it stops. The lower the object climbs, the lower the density of the liquid in the deceleration chamber 6, and the speed at which the object stops can be relatively accelerated, thereby accelerating the efficiency of the object's climbing.

[0041] The second hydraulic pressure value measured by the hydraulic control module is:

[0042]

[0043] Right now F2 is the second hydraulic pressure value of the liquid pump, V is the wind force, V max is the strongest wind force that the climber can withstand, h max The maximum height to which the climber can move;

[0044] Through hydraulic compensation of the liquid pump, the hydraulic pressure is further enhanced. When the object rises, it is affected by the wind and shakes. By measuring the wind force and optimizing the hydraulic data, the stability of the object when it stops can be further improved, avoiding the object from falling due to wind shaking, and greatly improving the climbing stability.

[0045] The third hydraulic pressure value measured by the hydraulic control module is:

[0046] When V>V mid When V mid For normal wind force: F3 is the third hydraulic pressure value of the liquid pump;

[0047] When V≤V mid When: F3 = F2;

[0048] When the wind is strong, the intensity of the object shaking is high. At this time, the third hydraulic value is used to further enhance the hydraulic size, so that the speed reduction plate 64 is enhanced by the liquid density, thereby enhancing the deceleration effect, which can ensure the stability of the object's stay to the greatest extent and fully avoid the phenomenon of the object falling.

[0049] The fourth hydraulic pressure value measured by the hydraulic control module is:

[0050] When V>V mid When V mid For normal wind force: F4 is the fourth hydraulic pressure value of the liquid pump;

[0051] When V≤V mid When: F4 = F2;

[0052] At the same time, when the wind is strong, the liquid pressure in the deceleration chamber 6 is relatively reduced, so as to avoid the deceleration plate 64 being subjected to excessive resistance and being unable to rotate into place, thereby preventing the object from being unable to move into place, improving the climbing quality of the object, and greatly improving the position accuracy of the object after movement.
