Description

Technical Field

[0001] The invention relates to a wind power tower climbing simulation technology, and in particular to an emergency braking somatosensory device. Background Art

[0002] At present, the height of the wind turbine nacelle is above 65 meters. When employees perform maintenance operations, they need to enter the nacelle through the tower by climbing a ladder. When using the ladder, they need to use a safety belt and anti-fall devices such as anti-fall blocks to work. New employees need to combine theory with practical teaching on the use of ladders, so that students can better grasp the importance and use of anti-fall devices when climbing ladders. Now a set of somatosensory devices with emergency brakes is invented for teaching and training. In order to solve the practical difficulties of the existing new employee teaching needing to go to the installation site of the wind turbine generator set, it is necessary to design an experience device with a simple structure, easy to use, and emergency braking. Imitating the human body accidentally falling when climbing the tower of the wind turbine generator set, the safety belt of the emergency brake experience device lifts the human body, protecting the operator's life and increasing the operator's safety awareness.

[0006] The brake mechanism is used to fix the brake rod in the slideway near the closed end of the brake housing in the non-braking state, and in the braking state, the brake rod is driven by the brake mechanism to be fixed in the slideway near the open end of the brake housing to achieve emergency braking;

[0007] The limiting component includes a slider, a limiting block and a spring; the slider is slidably disposed in a slide groove of a side wall of the slideway, and the slide groove extends along the length direction of the slideway;

[0008] The limit block is telescopically arranged on the slide block; the limit block extends out of the slide block in a braking state and is clamped in the limit groove of the brake rod to achieve brake rod braking.

[0009] Furthermore, the limit block has a force-applying surface, which is perpendicular to the length direction of the slideway; the surface in the limit groove that is in contact with the force-applying surface is a force-bearing surface, which is parallel to the force-applying surface.

[0010] Furthermore, the cross section of the slideway is circular, and the cross section of the brake rod is circular.

[0033] Example 1

[0034] like Figure 1-Figure 8 As shown:

[0035] An emergency brake somatosensory device, characterized in that it comprises: a telescopic stool 1 on which a human body stands, a safety belt 2 with one end tied around the waist of the human body and an emergency brake device arranged inside, and a crossbar 3 arranged above the head of the human body and arranged at the other end of the safety belt 2;

[0036] An emergency brake device 20 is arranged in the middle of the safety belt 2, and the emergency brake device 20 divides the safety belt 2 into two parts, an upper safety belt and a lower safety belt; the emergency brake device 20 includes a brake housing 21 provided with a slide 210, a brake mechanism 22 arranged on the inner wall of the brake housing 21, and a brake rod 23 arranged in the slide 210; one end of the brake housing 21 is connected to the lower safety belt, and the other end of the lower safety belt is tied to the waist of the human body; one end of the brake rod 23 is connected to the upper safety belt, and the other end of the upper safety belt is connected to the cross bar 3.

[0037] The brake rod 23 is provided with a limiting groove 230;

[0038] The inner wall of the slideway 210 is provided with a slide groove 2100;

[0039] The brake mechanism 22 is used to fix the brake rod 23 in the slideway 210 near the closed end of the brake housing 21 in the non-braking state, and in the braking state, the brake mechanism 22 clamps the brake rod 23 to the open end of the brake housing 21 to achieve emergency braking;

[0040] The braking mechanism 22 includes: an elastic component 220 and a limiting component 221; wherein the elastic component 220 is arranged between the closed end of the slideway 210 and the brake rod 23; the limiting component 221 is arranged in the slide groove 2100 of the side wall of the slideway 210, and is used to limit the brake rod 23 in the braking state, so that the brake rod 23 can achieve emergency braking when it slides toward the open end of the slideway 210 under the action of human body gravity;

[0041] A limiting groove 230 is provided at the lower part of the side wall of the brake rod 23;

[0042] The slide groove 2100 extends along the length direction of the slideway 210;

[0043] The elastic component 220 is arranged between the closed end of the brake housing 21 and the brake rod (23);

[0044] The limiting component 221 includes a slider 2210, a limiting block 2211 and a compression spring 2212; the slider 2210 is slidably set in the slide groove 2100; the limiting block 2211 is telescopically set on the slider 2210; the limiting block 2211 has a force-applying surface e, and the force-applying surface e is perpendicular to the length direction of the slide 210; the side of the limiting groove 230 that contacts the force-applying surface e is a force-bearing surface d, and the force-bearing surface d is parallel to the force-applying surface e.

[0045] The limit block 2211 is connected to the surface of the slider 2210 through the clamping spring 2212; in the non-braking state, the limit block 2211 slides toward the a end of the slide groove 2100 under the pulling force of the elastic component 220; in the braking state, under the action of the human body's gravity, the brake rod 23 slides toward the open end of the brake housing 21 until the limit block 2211 is engaged with the b end of the slide groove 2100.

[0046] like Figure 4 The cross section of the slideway 210 is circular, and the cross section of the brake rod 233 is circular;

[0047] The number of the limit blocks 2211 is 4, which are evenly arranged on the same cross-sectional circumference of the side wall of the slideway 210;

[0048] The number of the limiting grooves 230 is four and they are evenly arranged on the same cross-sectional circumference of the brake rod 233 .

[0049] The elastic component 220 is a linear spring, one end of which is fixed to the inner wall of the closed end of the slideway 210 on the brake housing, and the other end is fixedly connected to the brake rod 23. The linear spring is a tension spring. The elastic component 220 of the present invention is made of SUS304 stainless steel, which is a common material for making springs. It has good corrosion resistance, heat resistance, low temperature strength and mechanical properties. It is suitable for food processing, storage and transportation. It has good processing performance and weldability.

[0050] The telescopic stool 1 includes a base 10, a sleeve 11 disposed on the upper surface of the base 10, a spring 12 disposed in the sleeve 11 and fixedly connected to the base 10 at one end, a sliding column 13 slidably connected to the sleeve 11 and disposed at the other end of the spring 12, a table 15 fixedly connected to the sliding column 13, and a cylinder 14 fixedly connected to the base 10 at one end. The spring 12 is a tension spring, which accelerates the downward movement of the table 15 when in use to increase the weightlessness effect.

[0051] The working process of the technical solution provided in this embodiment is as follows: the subject stands on the table 15 of the telescopic stool 1, fastens the safety belt 2 around the waist, and the other end of the safety belt 2 is hung on the cross bar 3. During the test, the cylinder 14 suddenly contracts downward, and the subject is suspended in the air and makes an emergency landing under the action of gravity. At this time, the emergency braking device 20 arranged in the middle of the safety belt 2 realizes emergency braking.

[0052] The working process of the emergency brake device 20 is as follows: the human body falls rapidly, and the brake housing 21 falls downward under the drive of the human body. At this time, the limiting component 221 on the brake mechanism 22 slides from end a to end b in the slide groove 2100 of the brake housing 21. Finally, the slider 2211 on the brake mechanism 22 is stuck in the end b of the slide groove 2100, and the limiting block 2210 is stuck in the slot 230 of the brake rod 23, so that the brake rod 23 is stuck in the opening end of the brake housing (such as Figure 3 ), at which point the body stops sliding.

[0053] After the experiment, the cylinder 14 is raised and the human body stands firmly on the table 15. At this time, the emergency brake device is reset, and the reset process is as follows: the brake rod 23 slides toward the closed end of the brake housing 21 under the elastic force of the elastic component 220 until the limiting component 221 is stuck in the end a of the slide groove 2100, and the emergency brake device is reset.

[0054] In order to further improve the safety of the braking mechanism, a tension spring is used as the elastic component 220 in the emergency braking device. In case the braking mechanism 22 fails, the tension spring can also limit the position to prevent the human body from falling and getting injured. This improves safety during emergency braking and provides double protection for the human body.

[0055] Example 2

[0056] The structure of this embodiment is basically the same as that of embodiment 1, except that: the connection between the limiting component 221 and the brake rod 23 can adopt an electromagnetic structure, for example, the brake rod 23 is set as the N pole, and the limiting component 221 is set as the S pole. During the test, the brake rod 23 attracts the limiting block 2211 of the limiting component 221 into the limiting groove 230 of the brake rod 23 to achieve emergency braking when the human body falls; other action processes are consistent with embodiment 1.

[0057] Example 3

[0058] The structure of this embodiment is basically the same as that of embodiment 1, except that the emergency brake mechanism can be activated by manual operation, for example, a corresponding button is set on the operation panel, and the button is connected to the brake mechanism through a corresponding control circuit device. When the commander determines that emergency braking is required, he can press the button to control the brake mechanism to start braking. Alternatively, the emergency brake mechanism can also be triggered by a displacement detection component on the telescopic stool 1, and the displacement detection component is connected to the brake mechanism.

[0059] For example, when the displacement is detected to be 0.5 meters, the displacement detection component controls the braking mechanism to start braking.

[0060] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
