An anti-locking escape descent control device comprises a shell 1, a rope winding drum 2, a descent control rope, a first damping piece 3 and a second damping piece 4.
In this embodiment, as shown in fig. 1, the housing 1 includes two cover plates 11 arranged in parallel, a plurality of connecting posts 12 are disposed between the cover plates 11, threaded through holes are disposed inside the connecting posts 12, connecting holes are correspondingly disposed on the cover plates 11, and bolts pass through the connecting holes to connect with the threaded through holes.

A rotating shaft device 5 is installed in the middle of the rope winding drum 2, and the rotating shaft device 5 is driven by a transmission device 6 so that the rotating direction of the rotating shaft device 5 is different from the rotating direction of the rope winding drum 2.
The rotating shaft device 5 comprises a rotating shaft 51, and two ends of the rotating shaft 51 are respectively and rotatably connected with the two cover plates 11, so as to reduce the rotating friction. Bearings are fixed on the two cover plates 11, the rotating shaft 51 is in interference fit with the inner ring of the bearing, and the outer ring of the bearing is in interference fit with the bearing holes in the cover plates 11.
As shown in fig. 3, the transmission device 6 is a gear transmission device 6, and includes an inner gear 61, three planet wheels 62 and a sun wheel 63, wherein the sun wheel 63 is fixed to the rotating shaft 51, the inner gear 61 is fixed to the rope winding drum 2, the three planet wheels 62 are fixed to a transmission shaft, the transmission shaft is rotatably connected to the housing 1, the three planet wheels 62 are uniformly distributed along the circumferential direction of the rope winding drum 2, and each planet wheel 62 is respectively engaged with the inner gear 61 and the sun wheel 63. Wherein the diameter of the planet wheel 62 is larger than the diameter of the sun wheel 63 and the number of teeth of the planet wheel 62 is larger than the number of teeth of the sun wheel 63, so that the rotational speed of the rope drum 2 is smaller than the rotational speed of the rotating shaft arrangement 5.
As shown in fig. 2, the first damping member 3 is mounted on the rope drum 2 and the second damping member 4 is mounted on the spindle means 5. The second damping part 4, when the first damping part 3 rotates with the rope drum 2, rubs against the first damping part 3 so that the rope drum 2 decelerates.
Specifically, as shown in fig. 4, the rotating shaft device 5 further includes a driving ring 52 and a mounting bracket 53, wherein the mounting bracket 53 is fixed on the rotating shaft 51 and rotates synchronously with the rotating shaft 51. Specifically, the rotating shaft 51 is a stepped shaft, the middle of the rotating shaft 51 is provided with an annular boss 511, two sides of the annular boss 511 are respectively sleeved with a transmission ring 52, and the transmission ring 52 is connected with the rotating shaft 51 through a key to realize synchronous rotation. The mounting frame 53 comprises a sleeve 531 and a connecting disc 532, the sleeve 531 is sleeved on the two driving rings 52 at the same time, and the sleeve 531 and the driving rings 52 are connected through keys to realize synchronous rotation. The connecting plate 532 is provided with two and fixed at two ends of the sleeve 531 through bolts. Thus, the mounting bracket 53 can be rotated by the transmission shaft. The second damping member 4 is mounted in particular on a mounting bracket 53.
There are various combinations of the mounting manners and structures of the first damper 3 and the second damper 4, the friction time, and the like.
The mounting mode mainly comprises a fixing mode and a rotating mode. The specific combination can be as follows: mode 1: the first damping part 3 is fixed to the rope drum 2 and the second damping part 4 is rotatably arranged on the mounting bracket 53. Mode 2: the first damping part 3 is rotatably mounted on the rope drum 2 and the second damping part 4 is fixedly arranged on the mounting bracket 53. Mode 3: the first damping member 3 is rotatably mounted on the rope drum 2 and the second damping member 4 is rotatably arranged on the mounting bracket 53. Mode 4: the first damping part 3 is fixed to the rope drum 2 and the second damping part 4 is fixed to the mounting bracket 53.
In the above four modes, when the rotation mode is adopted, a connecting shaft is formed on the corresponding damping member, and the rotation is performed by inserting the connecting shaft into the rope winding drum 2. As shown in fig. 6, specifically, when the first damping member 3 is rotatably connected to the rope winding drum 2, the rope winding drum 2 protrudes inwards to form two mounting portions 23, the two ends of the first damping member 3 are both provided with connecting shafts 7, and the connecting shafts 7 are inserted into holes of the two mounting portions 23 to realize that the first damping member 3 rotates relative to the rope winding drum 2. In order to reduce the rotation resistance, a bearing can be arranged in the hole, the outer ring of the bearing is in interference fit with the hole, and the inner ring of the bearing is in interference fit with the connecting shaft. When the second damping member 4 is rotatably connected to the mounting bracket 53, as shown in fig. 5, a connecting shaft 7 is fixed to each end of the second damping member 4. The connecting disc 532 is provided with a bearing, the outer ring of the bearing is fixed with the connecting disc 532, and the inner ring of the bearing is fixed with the connecting shaft 7. Thereby achieving the pivotal attachment of the second damping member 4 to the mounting bracket 53.
When the fixing method is adopted, the fixing method is generally adopted by welding or bolt fixing. The specific way in which the first damping member 3 is fixed to the rope drum 2 is: as shown in fig. 2, an annular positioning portion 22 is formed on the inner wall of the rope winding drum 2, the positioning portion 22 is located at the middle position of the inner wall of the rope winding drum 2, and the first damping member 3 has a positioning groove 31 (fig. 5) matched with the positioning portion 22 so as to realize the axial quick positioning of the first damping member 3. Three connecting holes are uniformly distributed along the axial direction of the rope winding drum 2, three threaded blind holes are formed in the corresponding first damping piece 3, and the bolt penetrates through the connecting holes to be connected with the threaded blind holes. The first damping part 3 is bolted to the inner ring of the rope drum 2.
The specific way of fixing the second damping member 4 to the rope winding drum 2 is to provide a threaded through hole in the center of the second damping member 4, provide a corresponding connecting hole in each of the connecting discs 532 at the two ends, and connect the threaded through hole with a bolt passing through the connecting hole.
The above-mentioned connection means can be combined by themselves as desired, the advantage of the rotation being that individual friction surfaces of the damping element can be utilized, reducing the wear of the individual friction surfaces.
The structures of the first damping part 3 and the second damping part 4 can be various, such as arc-shaped convex structures, wave-shaped structures, cylindrical or cylinder-like structures, prismatic structures, spherical structures and the like, and can also be in a special-shaped combination type. It is mainly determined by the way of friction. The friction modes are mainly divided into two modes, one is friction in a surface contact mode, and the other is friction in a line contact mode.
For the surface contact friction, the contact surfaces of the first damping part 3 and the second damping part 4 are both curved surfaces, and the surface contact is formed in the curved surface and curved surface modes. The distance H between the contact surface of the first damping element 3 and the central axis of the rope drum 2 is equal to the distance H between the contact surface of the second damping element 4 and the central axis of the rope drum 2. Referring to fig. 7 in particular, the first damping member 3 is an annular structure, the second damping members 4 are both arc-shaped block-shaped structures, and the concave curved surface of the first damping member 3 is attached to the convex curved surface of the second damping member 4.
For the line contact friction, the contact surface of the first damping member 3 and the second damping member 4 may be a curved surface and a flat surface, and the line contact is formed in the curved surface and the flat surface. The combination of the curved surface and the plane is as follows: the curved surface is arranged on the first damping part 3, the plane is arranged on the second damping part 4 or the plane is arranged on the first damping part 3 and the curved surface is arranged on the second damping part 4. The first damping member 3 and the second damping member 4 may be curved surfaces, for example, the first damping member 3 and the second damping member 4 may be cylindrical structures.
It is of course also possible to combine surface contact with line contact, for example, referring to fig. 8, the first damping member 3 is of an annular configuration, the contact surface includes both a curved section 81 and a flat section 82, and the contact surface of the second damping member 4 is curved.
The material of the first damping member 3 and the second damping member 4 also affects the structural design of the damping member, wherein the first material design is: the first damping part 3 and the second damping part 4 are made of hard wear-resistant rubber or other hard materials. The first structural design is as follows: the contact position of the first damping element 3 and the second damping element 4 is the same as the distance from the central axis of the rope drum 2, and reference may be made to the above-mentioned specific manner of surface contact. It is of course also possible to use a line contact, which is on the same circle, the centre of which is on the central axis of the rope drum 2.
The second structure design: the first damping part 3 and the second damping part 4 have different contact positions to give different frictional forces to the first damping part 3 when the rope drum 2 rotates, and the different contact positions are different from the center axis distance of the rope drum 2 when the first damping part 3 and the second damping part 4 are not deformed. The contact position is here referred to as a position concept, which refers to the position of the point, line, plane of contact of the first damping element 3 and the second damping element 4 relative to the centre axis of the rope drum 2. The contact surface mentioned above refers to an area containing the contact sites.
Under the second structural design, the installation mode is generally selected as follows: at least one of the first damper 3 and the second damper 4 is capable of rotating, and when the rope reel 2 rotates, the first damper 3 and/or the second damper 4 rotates and generates friction when the first damper 3 and the second damper 4 are in contact with each other. In the specific application of the embodiment, the first damping member 3 is fixed, and the second damping member 4 is rotated. And the adopted mode is line contact, and the corresponding structures of the first damping part 3 and the second damping part 4 are as follows: the contact surface of the first damping part 3 is a curved surface, and the contact surface of the second damping part 4 is a plane. Specifically, the method comprises the following steps: as shown in fig. 2, the first damping member 3 has a semi-cylindrical structure, two inclined surfaces at two ends, and a contact surface (curved surface) at a side surface. The second damping member 4 is a prism structure, preferably a regular hexagonal prism, and two adjacent planes of the prism are transited through a cambered surface. The central axes of the first damping part 3 and the second damping part 4 are parallel to the central axis of the rope winding drum 2, so that the contact line of the semi-cylindrical structure and the regular hexagonal prism is parallel to the central axis of the rope winding drum 2.
Since the hexagonal prism can rotate, six side surfaces of the regular hexagonal prism are contact surfaces. Wherein the overall length of the first damping member 3 in the axial direction of the rope drum 2 is equal to the length of the second damping member 4 in the axial direction of the rope drum 2. However, due to the inclined surface at the end of the semi-cylindrical structure, the length of the shortest line on the contact surface of the semi-cylindrical structure (the length along the axial direction of the rope reel) is equal to the height of the hexagonal prism, wherein the height refers to the length of the hexagonal prism along the axial direction of the rope reel. As shown in fig. 9, the minimum distance between the contact surface of the first damping element 3 and the center axis of the rope drum 2 is equal to the minimum distance H between the contact surface of the second damping element 4 and the center axis of the rope drum 2. Wherein H is the distance between the straight line of the contact surface passing through the peak point on the semi-cylindrical structure and the central axis of the rope reel, and H is the distance between the central line of the contact surface of the hexagonal prism and the central axis of the rope reel.
The second material design is that at least one of the first damping part 3 or the second damping part 4 is made of elastic material. At this time, the difference of the contact positions can be realized by the damping structure design, for example, referring to fig. 10, the first damping member 3 is designed to be a wave crest structure, the second damping member 4 is designed to be a cylindrical structure, the contact surfaces of the two are curved surfaces, and a line or surface contact mode is adopted. Wherein the minimum distance H between the contact surface of the crest structure and the central axis of the rope winding drum 2 is smaller than the minimum distance H between the contact surface of the cylindrical structure and the central axis of the rope winding drum 2, so that the second damping part 4 and the first damping part 3 are in continuous friction contact on one section of crest surface of the crest structure, and the contact positions are all located on any contact line of the partial curved surface of the crest surface and the cylindrical structure. And in this case, the mounting is generally selected such that the first damper member 3 and the second damper member 4 are fixed. Of course selective rotation may also be achieved.
According to the friction time, continuous friction and intermittent friction can be divided. The continuous friction mode, as shown in fig. 7, for example, the first damping member 3 is configured as a ring-shaped structure, and the second damping member 4 is configured as a ring-shaped or arc-shaped block-shaped structure, in this way, the number of the first damping members 3 is 1, and in the arc-shaped block-shaped structure, a plurality of second damping members 4 are uniformly distributed along the circumferential direction of the rope winding drum 2, the number is generally determined according to the radian of the arc-shaped block-shaped structure, the smaller the radian is, the greater the number is, and fig. 7 is designed according to 6 arc-shaped block-shaped structures; it is of course also possible to arrange the second damping element 4 in an annular configuration.
Intermittent rubbing mode: mainly by the number and the position arrangement of the first damping member 3 and the second damping member 4. And the interval of intermittent rubbing cannot be too long for the slow descent effect. Therefore, it is preferable that each of the first damping member 3 and the second damping member 4 is provided in plurality at intervals in the circumferential direction of the rope reel 2. Of course, both of them can be realized in a single manner, and the first damping member 3 and the second damping member 4 are both in a rectangular arc-shaped block structure.
In this embodiment, it is preferable that the first damping members 3 are provided in plurality at regular intervals in the circumferential direction of the rope reel 2, and the second damping members 4 are provided in plurality at regular intervals in the circumferential direction of the rotating shaft device 5. Wherein the angle α separating two adjacent first damping members 3 is larger or smaller than the angle β separating two adjacent second damping members 4, which means that the number of first damping members 3 and second damping members 4 is unequal, i.e. the number of first damping members 3 is larger or smaller than the number of second damping members 4. The difference between the angle alpha and the angle beta is delta, the delta angle plays a major role in the pause time, preferably 5 DEG to 30 DEG delta. Further can be optimized to be delta being more than or equal to 10 degrees and less than or equal to 20 degrees. The contact angle between the first damping member 3 and the second damping member 4 is gamma, gamma is smaller than or equal to delta, and the actual intermittent angle delta-gamma is the difference between delta and gamma. When the line contact method is used, the γ angle can be regarded as 0 degree, and actually exceeds 0 degree.
In a preferred embodiment, there are at least two groups of second damping elements 4, each group comprising at least two second damping elements 4 distributed evenly in the circumferential direction of the rope drum 2. The number of the first damping parts 3 and the number of the second damping parts 4 are even numbers, and the number of the first damping parts 3 is more than that of the second damping parts 4. Specifically, in this scheme, first damping piece 3 sets up 8, and second damping piece 4 sets up 6, and two centrosymmetric second damping pieces 4 are a set of, 3 total. The first damping elements 3 are also two centrosymmetric sets of first damping elements 3 which rub against the second damping elements 4 one set at a time.
One end of the slow descent rope is connected with the rope winding drum 2 and wound on the rope winding drum 2, the other end of the slow descent rope is a free end, the free end is used for being connected with a fast descent main body, and the fast descent main body is generally an escape person or material; since the descent control rope is prior art, it is not shown in the figure.
The working process is as follows: when descending, the rope winding drum 2 is driven by the slow descending rope, the rope winding drum 2 drives the planet wheel 62 through the inner gear ring 61, the planet wheel 62 drives the sun wheel 63, the sun wheel 63 drives the rotating shaft 51, and the rotating shaft 51 drives the mounting frame 53 to rotate. During the rotation, the contact surface of the second damping member 4 strikes the contact surface of the first damping member 3, and the second damping member 4 rotates and rubs against the first damping member 3.

It will be appreciated by those skilled in the art that the scope of the invention in the embodiments of the present disclosure is not limited to the specific combination of the above-mentioned features, but also encompasses other embodiments in which any combination of the above-mentioned features or their equivalents is made without departing from the inventive concept as defined above.
