Description

Technical Field

[0001] The utility model relates to the technical field of high altitude anti-falling, and more specifically, to an anti-falling accompanying system which is externally mounted on a guide rail and is suitable for various environmental working conditions. Background Art

[0002] In daily work, there are many situations where you need to pass through high-risk environmental conditions, especially in vertical climbing, edge working, slope passage or high-risk environments with alternating combinations of working conditions. Maintenance personnel frequently pass through or work for a long time in this environment, and there is a risk of personal injury. In order to implement the production concept of "life first, safety first", how to achieve all-round safety protection for construction workers when passing or repairing in high-risk environments is an urgent problem to be solved by our operation and maintenance units.

[0003] At present, for safety protection in different high-risk environments, only segmented protection measures can be used to protect maintenance personnel. Common measures are as follows:

[0004] 1. For the safety protection of vertical climbing working conditions, a mechanical structure type of wire rope anti-fall brake is generally used to effectively protect the vertical climbing working conditions, which can ensure the safe passage of maintenance personnel when climbing up and down in vertical working conditions;

[0005] Second, for the safety protection of horizontal edge working conditions, the horizontal edge parts are generally protected by installing isolation fences and safety ropes to ensure the safe passage of maintenance personnel in this area;

[0006] 3. For the safety protection of slope passage conditions, it is generally adopted to install protective fences on both sides of the slope passage or use a mechanical structure type of wire rope anti-fall brake at the top of the slope to ensure the safety of slope passage for maintenance personnel under slope conditions;

[0007] However, in actual work sites, there are generally multiple working conditions combined with each other. Different protective measures need to be formulated to ensure the safe passage of maintenance personnel. Moreover, the various protective measures cannot be effectively connected, which increases the difficulty of management. Utility Model Content

[0008] The technical problem to be solved by the utility model is to provide a fall prevention accompanying system which is externally mounted on a guide rail and is applicable to various environmental working conditions. The system is used in conjunction with the guide rail to achieve full-line safety protection for maintenance personnel during climbing or passing in various high-risk environmental working conditions, thereby ensuring the safety of operations in complex environmental working conditions.

[0009] The solution adopted by the utility model to solve the technical problem is:

When the braking mechanism is in normal passage (climbing up, climbing down, and horizontal passage), the braking mechanism will not contact or overlap with the anti-fall platform under the force applied by the safety belt or the force applied by the unlocking mechanism; the force applied by the unlocking mechanism to the braking mechanism to prevent contact or overlap with the anti-fall platform is mainly used in slope conditions, that is, when the guide rail is set at an angle;

[0013] During the fall braking, the maintenance personnel fall vertically downward, and the safety belt they wear applies force to the braking mechanism, so that the braking mechanism and the anti-fall platform overlap and cooperate, limiting the sliding of the entire accompanying mechanism along the length direction of the guide rail, thereby realizing the fall protection for the maintenance personnel;

[0017] The sliding block comprises a main body which is used for installing a traveling mechanism and is provided with an avoidance hole, and an ear seat which is installed on a side of the main body away from the traveling mechanism and is used for installing a braking mechanism and an unlocking mechanism.

[0018] In some possible implementations, in order to enable the braking mechanism to cooperate with the anti-fall platform and the safety belt to achieve emergency braking;

[0020] During normal passage, the locking rod abuts against the bottom surface of the avoidance hole and the end away from the rotating shaft is located in the avoidance chute and forms a gap between the anti-fall platform;

[0021] During emergency braking, the locking rod abuts against the top surface of the avoidance hole, and the end thereof away from the rotating shaft passes through the slide groove into the limiting groove and overlaps with the anti-falling platform.

[0023] The top surface of the avoidance hole is inclined and forms an angle a with the Z-axis direction, and the bottom surface of the avoidance hole is inclined and forms an angle b with the Z-axis direction, where b>a.

[0024] In some possible implementations, in order to effectively enable maintenance personnel to effectively slide the accompanying mechanism on the guide rail when they pass downward under slope conditions;

[0025] The unlocking mechanism includes a Y-axis arranged along the Y-axis direction and having two ends passing through the ear seats, two groups of bosses arranged on the Y-axis, and two groups of Y-axis elastic members sleeved on the Y-axis and located on the side away from the two groups of bosses;

[0026] A matching gap is formed between the two groups of bosses to abut against the suspension rod.

[0027] In some possible implementations,

[0028] The two groups of bosses are both in the shape of a frustum, and their small ends are arranged on the side close to each other.

[0029] In some possible implementations, in order to effectively implement the installation of the braking mechanism and the unlocking mechanism;

[0030] The ear seats are in two groups and are symmetrically arranged along the X-axis direction. The ear seats are respectively provided with torsion spring mounting holes for mounting a reset torsion spring and boss avoidance holes for boss installation; the Y-direction elastic member is located in the boss avoidance holes.

[0031] In some possible implementations, in order to effectively realize the external coordination between the guide rail and the walking mechanism;

[0032] The walking mechanism comprises two groups of pulleys symmetrically arranged along the length direction of the guide rail and slidingly matched with the outer side of the upper flange;

[0033] Each group of pulley blocks includes a mounting shaft connected to the body and arranged along the Z-axis direction, and a pulley sleeved on the outside of the mounting shaft and rotatably matched with the mounting shaft; the pulley is a groove pulley.

[0034] A method for using the above-mentioned anti-fall accompanying system which is externally mounted on a guide rail and is suitable for various environmental working conditions,

[0035] When the maintenance personnel pass upward, the safety belt connected to the brake mechanism will apply force to the brake mechanism, and the brake mechanism will rotate counterclockwise around the Y-axis direction and abut against the bottom surface of the avoidance hole, so that the brake mechanism does not contact with the anti-fall platform;

[0036] When the maintenance personnel pass downward on the vertically arranged guide rail, the safety belt connected to the brake mechanism will apply force to the brake mechanism, causing the brake mechanism to rotate counterclockwise around the Y-axis direction, and the brake mechanism abuts against the bottom surface of the avoidance hole, and the brake mechanism does not contact the anti-fall platform;

[0057] The utility model is described in detail below.

[0058] Embodiment 1:

[0059] like Figure 1-Figure 10 As shown:

[0060] A fall prevention accompanying system externally mounted on a guide rail and applicable to various environmental working conditions, comprising a guide rail 10 arranged along the X-axis direction in the length direction, and an accompanying mechanism 20 slidably matched with the guide rail 10 and sliding along the length direction of the guide rail 10; a plurality of groups of fall prevention platforms 101 are arranged on the guide rail 10 and along the length direction thereof, and a limiting groove 102 is formed between two adjacent groups of fall prevention platforms 101;

[0061] It should be noted that the guide rail 10 in the present invention can be arranged vertically, inclined or horizontally; the vertical arrangement corresponds to the vertical climbing condition; the inclined arrangement corresponds to the slope passing condition; the horizontal arrangement corresponds to the horizontal edge condition;

[0062] The accompanying mechanism 20 includes a slider 1 installed above the guide rail 10, a walking mechanism 2 installed at the bottom of the slider 1 and slidingly cooperating with the guide rail 10 along the length direction of the guide rail 10, a braking mechanism 3 rotatably installed on the slider 1 and one end of which passes through the slider 1 and is used in conjunction with the anti-fall platform 101, and an unlocking mechanism 4 slidably installed on the slider 1 and used in conjunction with the braking mechanism 3; the braking mechanism 3 rotates with the slider 1 around the Y-axis direction, and the unlocking mechanism 4 slides with the slider 1 along the Y-axis direction; an avoidance hole 13 is provided on the slider 1 for one end of the braking mechanism 3 to pass through;

[0063] The traveling mechanism 2 is externally mounted on the guide rail 10 and slidably cooperates with the guide rail 10 to realize the sliding of the accompanying mechanism 20 along the long direction of the guide rail 10;

[0064] When in use, the brake mechanism 3 is connected to the safety belt worn by the maintenance personnel. When the brake mechanism 3 is in normal passage (climbing up, climbing down, and horizontal passage), the brake mechanism 3 will not contact or overlap with the anti-fall platform 101 under the force applied by the safety belt or the force applied by the unlocking mechanism 4; wherein, the force applied by the unlocking mechanism 4 to the brake mechanism 3 to prevent contact or overlap with the anti-fall platform 101 is mainly used in slope conditions, that is, when the guide rail 10 is set at an angle;

[0065] The unlocking mechanism 4 moves along the Y-axis direction, which can drive the braking mechanism 3 to rotate counterclockwise around the Y-axis direction, so that when climbing down the slope, the anti-fall platform 101 does not come into contact with the braking mechanism 3, and can pass smoothly;

[0066] During the fall braking, the maintenance personnel falls vertically downward, and the safety belt they wear applies force to the brake mechanism 3, so that the brake mechanism 3 overlaps and cooperates with the anti-fall platform 101, limiting the sliding of the entire accompanying mechanism 20 along the length direction of the guide rail 10, thereby realizing the fall protection for the maintenance personnel;

[0067] In some possible implementations, in order to effectively realize the external hanging of the traveling mechanism 2 and the guide rail 10 connected to the slider 1, and enable the accompanying mechanism 20 to slide along the length direction of the guide rail 10;

[0068] The cross section of the guide rail 10 is an I-shaped structure, including an upper flange, a web, and a lower flange used in conjunction with the walking mechanism 2. The upper flange is located at the bottom of the slider 1 and a side close to the slider 1 is provided with an avoidance chute, the avoidance chute is arranged along the length direction of the guide rail 10, and the anti-fall platform 101 is located in the avoidance chute; the avoidance hole 13 is located directly above the avoidance chute, and one end of the brake mechanism 3 will pass through the avoidance hole 13 and extend into the avoidance chute;

[0069] During normal use, the end of the brake mechanism 3 will be located in the avoidance slot; during emergency braking, the brake mechanism 3 rotates counterclockwise around the Y-axis direction, so that the end of the brake mechanism 3 extending into the avoidance slot contacts and cooperates with the top surface of the avoidance hole 13, and the free end of the brake mechanism 3 will extend into the limit slot 102, and after the accompanying mechanism 20 slides down a short distance, it will overlap with the adjacent anti-falling platform 101 to achieve braking;

[0070] Furthermore, the anti-fall platforms 101 are multiple groups and are arranged at equal intervals along the length direction of the avoidance chute.

[0071] In some possible implementations, in order to realize the installation of the braking mechanism 3, the unlocking mechanism 4, and the walking mechanism 2;

[0072] like Figure 2 , Figure 4 As shown, the slider 1 includes a body 11 for mounting the traveling mechanism 2 and provided with an avoidance hole 13, and an ear seat 12 mounted on the side of the body 11 away from the traveling mechanism 2 and used for mounting the braking mechanism 3 and the unlocking mechanism 4; a gap is formed between the body 11 and the guide rail 10;

[0073] Furthermore, the ear seats 12 are in two groups and are symmetrically arranged along the X-axis direction, thereby effectively supporting and fixing the braking mechanism 3 and the unlocking mechanism 4;

[0074] The body 11 is arranged on the outside of the upper flange (above the upper flange) and the two are arranged in parallel; the walking mechanism 2 is connected to the body 11 and slides with the two side surfaces of the upper flange along the X-axis direction; the ear seat 12 is arranged on the side of the body 11 away from the upper flange for the installation of the braking mechanism 3 and the unlocking mechanism 4;

[0075] Furthermore, handles 5 are respectively provided on the sides of the two sets of ear seats 12 that are away from each other, and the two sets of handles 5 are symmetrically arranged along the X-axis direction;

[0076] In some possible implementations, in order to enable the brake mechanism 3 to cooperate with the anti-fall platform 101 and the safety belt to achieve emergency braking;

[0077] like Figure 5 As shown, the braking mechanism 3 includes a rotating shaft 31 arranged along the Y-axis direction and rotatably mounted on the ear seat 12, a return torsion spring 32 sleeved on the outside of the rotating shaft 31 and connected to the ear seat 12, a locking rod 33 connected to the rotating shaft 31 at one end and extending into the avoidance chute at the other end, and a hanging rod 34 connected to the rotating shaft 31 at one end and provided with a hanging hole 341 at the other end;

[0078] During normal passage, the locking rod 33 abuts against the bottom surface of the avoidance hole 13 and the end away from the rotating shaft 31 is located in the avoidance chute and forms a gap with the anti-fall platform 101;

[0079] The reset torsion spring 32 is sleeved on the outer side of the rotating shaft 31, one end of which is connected to the rotating shaft 31 and the other end is connected to the ear seat 12, so that the brake mechanism 3 can be automatically reset; the hanging rod 34 is connected to the safety belt worn by the maintenance personnel through the hanging hole 341. When climbing up or down in a vertical climbing condition or climbing up in a slope condition, the safety belt will apply a force to the hanging rod 34 away from the guide rail 10 under the action of the maintenance personnel, driving the rotating shaft 31 to rotate counterclockwise, so that the locking rod 33 contacts the bottom surface of the avoidance hole 13, so that the anti-fall platform 101 does not overlap with the end of the locking rod 33 to achieve passage;

[0080] During emergency braking, if the maintenance personnel accidentally fall from a high hole, the accompanying mechanism 20 will no longer be affected by the force provided by the safety belt and will return to its initial state under the action of the reset torsion spring 32; when the rope connecting the safety belt and the suspension rod 34 is straightened, a downward force will be applied to the suspension rod 34, so that the suspension rod 34 drives the rotating shaft 31 to rotate clockwise around the Y-axis direction, thereby causing the locking rod 33 connected to the rotating shaft 31 to rotate clockwise, and causing the locking rod 33 to abut against the top surface of the avoidance hole 13 and the end away from the rotating shaft 31 will pass through the slide groove into the limit groove 102 and overlap with the anti-fall platform 101 to achieve emergency braking.

[0081] Furthermore, the locking rod 33 and the hanging rod 34 form a V-shaped structure and the angle formed between the two groups is an obtuse angle, that is, Fig. 9 The middle angle A is an obtuse angle, and its opening is arranged on a side close to the unlocking mechanism 4;

[0082] like Fig. 9 , Fig.10 As shown, the guide rail 10 is arranged vertically, the unlocking mechanism 4 is arranged at the bottom of the body 11 (the side close to the ground) and below the braking mechanism 3, and the opening of the V-shaped structure is arranged downward along the length direction of the guide rail 10 and cooperates with the bottom of the suspension rod 34;

[0083] In some possible implementations, in order to effectively limit the rotation angle of the locking rod 33, and to achieve emergency braking when the locking rod 33 contacts the top surface of the avoidance hole 13, and to enable normal passage when the locking rod 33 contacts the bottom surface of the avoidance hole 13;

[0084] The avoidance hole 13 is tilted downward and connected to the avoidance chute; the top surface of the avoidance hole 13 is tilted and the angle formed with the Z-axis direction is a, the bottom surface of the avoidance hole 13 is tilted and the angle formed with the Z-axis direction is b, b>a; wherein a and b are both acute angles.

[0085] The angle formed by the top surface of the avoidance hole 13 and the Z-axis direction is smaller than the angle formed by the top surface of the avoidance hole 13 and the Z-axis direction, so that the locking rod 33 can overlap with the anti-fall platform 101 when contacting the top surface of the avoidance hole 13, thereby achieving braking; and when contacting the bottom surface of the avoidance hole 13, the free end of the locking rod 33 will not contact the anti-fall platform 101 close to each other, thereby achieving passage.

[0086] In some possible implementations, in order to effectively enable the accompanying mechanism 20 to slide on the guide rail 10 when maintenance personnel pass downward under a slope condition;

[0087] The unlocking mechanism 4 is arranged in the V-shaped opening;

[0088] like Figure 6 As shown, the unlocking mechanism 4 includes a Y-axis shaft 41 arranged along the Y-axis direction and having two ends passing through the ear seat 12, two groups of bosses 42 arranged on the Y-axis shaft 41, and two groups of Y-axis elastic members 43 sleeved on the Y-axis shaft 41 and located on the side away from the two groups of bosses 42;

[0089] A matching gap 44 is formed between the two groups of bosses 42 to abut against the suspension rod 34;

[0090] The Y-direction elastic member 43 enables the Y-direction axis 41 to return to its initial position when no external force is applied, and at this time, the bottom of the suspension rod 34 will be located in the fitting gap 44;

[0091] The Y-axis 41 can slide on the ear seat 12 along the Y-axis direction, thereby controlling the movement of the two sets of bosses 42. During the movement of the bosses 42, the bosses 42 squeeze the hanging rod 34 to make it rotate counterclockwise around the rotating shaft 31, driving the rotating shaft 31 and the locking case connected to the rotating shaft 31 to rotate counterclockwise around the Y-axis direction, thereby making the locking rod 33 contact the bottom surface of the avoidance hole 13, and the end of the locking rod 33 does not contact the anti-falling platform 101, thereby realizing downward climbing under the condition of slope passage;

[0092] In some possible implementations,

[0093] like Figure 6 As shown, the two groups of bosses 42 are both in the shape of a frustum, and their small ends are arranged on the side close to each other.

[0094] Since the boss 42 is in the shape of a cone, when the boss 42 moves along the Y-axis direction, the bottom surface of the suspension rod 34 is squeezed by the boss 42 and rotates counterclockwise around the Y-axis direction, thereby driving the locking rod 33 to rotate counterclockwise around the Y-axis direction, so that the locking rod 33 does not contact the anti-fall platform 101, thereby achieving downward climbing under the slope passage condition;

[0095] In some possible implementations, in order to effectively implement the installation of the braking mechanism 3 and the unlocking mechanism 4;

[0096] like Figure 4 As shown, the ear seat 12 is provided with a torsion spring installation hole 121 for installing the reset torsion spring 32 and a boss avoidance hole 122 for installing the boss 42; the Y-direction elastic member 43 is located in the boss avoidance hole 122;

[0097] The torsion spring mounting hole 121 is coaxially arranged with the rotating shaft 31, the rotating shaft 31 is located in the torsion spring mounting hole 121, and the reset torsion spring 32 is sleeved on the outer side of the rotating shaft 31 and is located in the torsion spring mounting hole 121;

[0098] Further, the torsion spring installation hole 121 includes a torsion spring hole for installing the reset torsion spring 32, a through hole coaxially connected to the torsion spring hole and passed through by the rotating shaft 31, and the through hole is arranged on the side where the two groups of bosses 42 are close to each other; the diameter of the through hole is smaller than the diameter of the torsion spring hole; and a connecting groove connected to one end of the reset torsion spring 32 is arranged in the torsion spring hole;

[0099] The boss avoidance hole 122 includes a hole for mounting on the boss 42, a small hole coaxially connected with the hole and for the Y-axis 41 to pass through, and the distance between the holes is larger than the distance between the small holes;

[0100] The boss 42 is fixedly mounted on the outside of the Y-axis shaft 41 and is coaxially arranged. The Y-axis shaft 41 will pass through the boss avoidance hole 122. The boss 42 will be located in the boss avoidance hole 122 in the initial state. The Y-axis elastic member 43 is a spring, and its two ends are respectively connected to the bottom of the boss avoidance hole 122 and the boss 42; when the Y-axis shaft 41 is subjected to a force along the Y-axis direction, the two groups of bosses 42 move along the Y-axis direction, one group of Y-axis elastic members 43 is in a compressed state, and the other group is in a stretched state; when the Y-axis shaft 41 is not subjected to a force, the two groups of Y-axis elastic members 43 will return to the initial state, so that the matching gap 44 is located directly below the suspension rod 34;

[0101] In some possible implementations, in order to effectively realize the external coordination between the guide rail 10 and the walking mechanism 2;

[0102] like Figure 1 As shown, the walking mechanism 2 includes two groups of pulleys symmetrically arranged along the length direction of the guide rail 10 and slidingly matched with the outer side of the upper flange;

[0103] Each pulley group includes a mounting shaft 22 connected to the body 11 and arranged along the Z-axis direction, and a pulley sleeved on the outside of the mounting shaft 22 and rotatably matched with the mounting shaft 22; the pulley is a groove pulley 21;

[0104] Furthermore, a support boss 42 is provided on one side of the body 11 close to the pulley;

[0105] The annular groove provided on the groove pulley 21 cooperates with the two side surfaces of the upper flange along the X-axis direction so that the pulley block and the guide rail 10 will not separate;

[0106] Furthermore, a through hole 14 for use with the installation shaft 22 is provided on the body 11, and a thread is provided on one end of the installation shaft 22 close to the body 11, and the installation shaft 22 and the body 11 are fixed by a nut;

[0107] Embodiment 2:

[0108] like Fig.11 As shown, the difference between this embodiment and embodiment 1 is that the structure of the walking mechanism is different. In the above embodiment, the walking mechanism cannot realize turning and changing direction for passing;

[0109] The walking mechanism 2 includes a front pulley block rotatably mounted on the body 11 and located on the side of the brake mechanism 3 away from the unlocking mechanism 4, and a rear pulley block mounted on the body 11 and located on the side of the unlocking mechanism 4 away from the brake mechanism 3; the front pulley block rotates with the body along the Z-axis direction, so that when turning or changing direction, the entire device can be moved along the axial direction of the guide rail 10 by rotating the front pulley block to achieve turning or changing direction;

[0110] The front pulley assembly includes a support plate 25 arranged on the side of the body 11 close to the guide rail 10, a screw 23 installed on the support plate 25 and used to connect the support plate 25 and the body 11, an adjusting nut 24 arranged on the body 11 and used in conjunction with the screw 23, and two groups of front pulleys symmetrically arranged along the length direction of the guide rail 10 and slidingly matched with the outer side of the upper flange; the front pulley includes a groove pulley 21 slidingly matched with the outer side of the upper flange, and a mounting shaft 22 used to connect the groove pulley 21 and the support plate 25 and arranged along the Z-axis direction; the body 11 is provided with a through hole for the screw 23 to pass through and rotate in conjunction with;

[0111] Furthermore, a groove having the same profile as the support plate 25 is provided at the bottom of the body 11, and the support plate 25 is assembled with the body 11 and is located in the groove, and a gap is formed between the support plate 25 and the outer side surface of the guide rail 10;

[0112] The screw 24 is arranged along the Z-axis direction, and its threaded section will pass through the side of the body 11 away from the guide rail 10, and the support plate 25 is connected to the body 11 through the connection with the adjusting nut 24; by controlling the rotation of the screw around the Z-axis direction, the accompanying mechanism 20 can slide along the guide rail 10 to achieve turning or changing direction;

[0113] The two groups of groove pulleys 21 in the two groups of front pulleys are connected to the support plate 25 through the installation shafts 22 arranged along the Z-axis direction and rotate with the corresponding installation shafts 22. The annular grooves respectively arranged on the two groups of groove pulleys 21 will cooperate with the side surfaces of the guide rail 10 along the X-axis direction to slide;

[0114] The rear pulley assembly includes two groups of rear pulleys symmetrically arranged along the length direction of the guide rail 10 and slidingly matched with the outer side of the upper flange; the rear pulley has the same structure as the front pulley and is connected to the body 11 through the mounting shaft 22;

[0115] The two groups of groove pulleys 21 in the two groups of rear pulleys are rotatably matched with the body 11 through the mounting shaft 22; the annular grooves respectively provided on the groove pulleys 21 will cooperate with the side surfaces of the guide rail 10 along the X-axis direction to achieve sliding;

[0116] The mounting shaft 22 and the groove pulley 21 are coaxially arranged;

[0117] like Fig.12 The two sets of guide rails 10 are perpendicular to each other and are connected in a smooth transition, for example, when the guide rail of a vertical climbing condition is connected to the guide rail of a horizontal edge condition; the accompanying mechanism 20 slides on the slideway formed by the slide grooves of the two sets of guide rails 10, and when turning from the horizontal edge condition to the vertical climbing condition, the front pulley block can realize the turning on the slideway due to the rotation cooperation with the main body 11.

[0118] A method for using the above-mentioned anti-fall accompanying system which is externally mounted on a guide rail and is suitable for various environmental working conditions,

[0119] When the maintenance personnel pass upward, the safety belt connected to the brake mechanism 3 will apply a force to the brake mechanism 3, and the brake mechanism 3 will rotate counterclockwise around the Y-axis direction and abut against the bottom surface of the avoidance hole 13, so that the brake mechanism 3 does not contact the anti-fall platform 101;

[0120] Specifically, when climbing upward in a vertical climbing condition, the chest hanging point of the safety belt worn by the maintenance personnel is connected to the hanging rod 34 through a rope; when climbing upward in a slope passage condition, the waist hanging point of the safety belt worn by the maintenance personnel is connected to the hanging rod 34 through a rope; when the maintenance personnel climb upward, the hanging rod 34 will be subjected to an upward force, thereby rotating counterclockwise around the Y axis, driving the rotating shaft 31 and the locking rod 33 to rotate counterclockwise around the Y axis, so that the locking rod 33 contacts the bottom surface of the avoidance hole 13, so that the end of the locking rod 33 close to the anti-fall platform 101 does not overlap with the anti-fall platform 101, thereby realizing upward passage;

[0121] When the maintenance personnel pass downward on the vertically arranged guide rail 10, the safety belt connected to the brake mechanism 3 will apply a force to the brake mechanism 3, so that the brake mechanism 3 rotates counterclockwise around the Y-axis direction, and the brake mechanism 3 abuts and cooperates with the bottom surface of the avoidance hole 13, and the brake mechanism 3 does not contact the anti-fall platform 101;

[0122] Specifically, when the maintenance personnel pass downward on the vertically arranged guide rail 10, the chest hanging point of the safety belt is connected to the hanging rod 34, and the hanging rod 34 is pulled backward through the chest hanging point to rotate the hanging rod 34 counterclockwise around the Y-axis direction, so that the end of the locking rod 33 close to the anti-falling platform 101 does not overlap with the anti-falling platform 101, and the maintenance personnel can climb downward without hindrance;

[0123] When the maintenance personnel pass downward on the inclined guide rail 10, they control the unlocking mechanism 4 to move along the Y-axis direction, push the braking mechanism 3 to rotate counterclockwise around the Y-axis direction, and the braking mechanism 3 abuts against the bottom surface of the avoidance hole 13, so that the braking mechanism 3 does not contact the anti-falling platform 101;

[0124] Specifically, when the maintenance personnel pass downward on the inclined guide rail 10, the waist suspension point of the safety belt is connected to the suspension rod 34. The maintenance personnel applies a force to the Y-axis 41 along the Y-axis direction, triggering the boss 42 of the Y-axis 41 to push the bottom of the suspension rod 34 upward, so that the suspension rod 34 rotates counterclockwise around the Y-axis direction, and then the locking rod 33 rotates counterclockwise. The end of the locking rod 33 close to the anti-fall platform 101 does not overlap with the anti-fall platform 101, so the maintenance personnel can climb downward without hindrance.

[0125] During emergency braking, when the maintenance personnel falls vertically downward, the brake mechanism 3 rotates clockwise around the Y-axis direction, the brake mechanism 3 abuts against the top surface of the avoidance hole 13, and the brake mechanism 3 and the anti-falling platform 101 overlap and brake;

[0126] Specifically, when a fall from a height occurs, the entire accompanying mechanism 20 is not subjected to force at this time and returns to its initial state. When the rope connecting the suspension rod 34 and the safety belt is straightened, the suspension rod 34 will be subjected to a downward force, causing the suspension rod 34 to move clockwise around the Y-axis, causing the rotating shaft 31 and the locking rod 33 to move clockwise, thereby causing the locking rod 33 to contact the top surface of the avoidance hole 13. At this time, the end of the locking rod 33 close to the guide rail 10 will extend into the limit groove 102. As the accompanying mechanism 20 slides downward along the guide rail 10, it will overlap with the adjacent anti-fall platform 101 to achieve braking, thereby achieving anti-fall protection for maintenance personnel.

[0127] The present invention is not limited to the above-mentioned specific implementation modes, but extends to any new features or any new combination disclosed in this specification, as well as any new method or process steps or any new combination disclosed.
