Description

Technical Field

[0001] The invention relates to the technical field of aerial work safety equipment, and in particular to a track-type anti-falling device. Background Art

[0002] In the process of using and maintaining special equipment such as gantry cranes and ship lifts, personnel need to frequently go up and down, involving high places and edges, and there are major safety hazards. In order to avoid personal injury accidents such as falling from high places due to hand slipping, sudden illness, heat stroke, etc., a fall arrester is often used. At present, the fall arrester on the market is often used in conjunction with the track. When the personnel fall, the brake components in the fall arrester will be driven to rub against the track to achieve the effect of braking and falling prevention. For example, the Chinese patent document with the announcement number CN208785631U discloses a track-type high-altitude fall arrester, including a fall prevention seat body, a swing rod and an elastic reset member, one end of the swing rod is a brake end and is provided with a protruding brake tooth, and the swing rod is swingably connected to the fall prevention seat body. When a fall accident occurs, the swing rod swings under the gravity of the human body, and the brake tooth on the brake end is in the guide groove and stuck on the guide rail to prevent further falling, thereby achieving the effect of safety protection. However, when the operator moves downward, it is easy to cause the swing arm to swing, causing the brake tooth to get stuck on the guide rail, thereby affecting the normal movement of the operator and having poor reliability.

DETAILED DESCRIPTION

[0026] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] In the description of the present invention, it should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0028] In the present invention, unless otherwise clearly specified and limited, the terms "assemble", "connect", "connect", "fix" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0029] Figures 1 to 9An embodiment of the track-type anti-falling device of the present invention is shown. The track-type anti-falling device of this embodiment includes a slide rail 1, a slide seat 2 that can slide along the slide rail 1, and a hook 3 arranged on the slide seat 2. A plurality of locking holes 11 are arranged at intervals along the length direction on the side wall of the slide rail 1. The slide seat 2 is provided with an acceleration sensor, a control module, a locking pin 4, and a driving component 7 for driving the locking pin 4 to extend into the locking hole 11. The acceleration sensor is connected to the input end of the control module by signal, and the output end of the control module is connected to the driving component 7 by signal. It should be noted that the slide rail 1 must be fixed before use (the slide rail 1 can be fixed on the stair handrail of the special equipment, or on an independent column, and the fixed position is selected according to the specific needs). The operator binds the safety rope on his body to the hook 3. When the operator moves, the safety rope will pull the hook 3, thereby driving the slide seat 2 to move on the slide rail 1.

[0030] The operating principle of the track-type anti-falling device of this embodiment is as follows: the acceleration sensor arranged on the slide 2 can send the acceleration data of the slide 2 to the control module in real time. The output end of the control module is connected to the drive component 7. When the acceleration value received by the control module exceeds the set value (i.e., the operator may fall or fall), the control module will send an action signal to the drive component 7, and the drive component 7 will drive the lock pin 4 to extend into the locking hole 11. After the lock pin 4 is inserted into the locking hole 11, the slide 2 cannot continue to move, thereby preventing the operator from moving.

[0031] The track-type anti-falling device of this embodiment is provided with an acceleration sensor and a control module. The control module will send an action signal to the drive component 7 only when the acceleration of the slide 2 reaches above the set value, and the drive lock pin 4 extends into the locking hole 11 to prevent the slide 2 from continuing to move. It has good reliability and is not easily affected by the normal movement of the operator, thereby improving the safety of the operator during normal movement.

[0032] See Figure 3 and Figure 5 Furthermore, in this embodiment, the slide 2 is provided with a connecting rod 5 and a push rod 6, the driving assembly 7 is connected to one end of the push rod 6, one end of the connecting rod 5 is hinged to the push rod 6, and the other end of the connecting rod 5 is movably connected to the lock pin 4. When the driving assembly 7 receives the action signal, it will push the push rod 6 to move. Since the push rod 6 is connected to the lock pin 4 through the connecting rod 5, the lock pin 4 will be driven to move during the movement of the push rod 6, so that one end of the lock pin 4 extends out of the slide 2 and is inserted into the locking hole 11.

[0033] See Figure 3 and Figure 5Furthermore, in this embodiment, the connecting rod 5 is an arc-shaped rod, which can reduce the stress inside the connecting rod 5 when the connecting rod 5 moves relative to the locking pin 4 and the push rod 6, and can extend the service life. The slide seat 2 is provided with a guide slot 16, and one end of the arc-shaped rod connected to the locking pin 4 can be slidably arranged in the guide slot 16, which is conducive to ensuring that the push rod 6 moves in the correct direction and drives the locking pin 4 to normally extend into the locking hole 11.

[0034] See Figures 1 to 5 Furthermore, in this embodiment, the locking holes 11 are provided on both side walls of the slide rail 1, and the connecting rods 5 and the locking pins 4 are provided on both sides of the push rod 6, which is beneficial to improve the stability of the slide 2 when locked. Specifically, the spacing between adjacent locking holes 11 on the same side wall of the slide rail 1 is 5 cm. After the control module sends an action signal, the braking distance of the slide 2 is short, which is beneficial to ensure the safety of the operator. Of course, in other embodiments, the spacing between adjacent locking holes 11 on the same side wall of the slide rail 1 can also be other lengths, as long as it can ensure that the slide rail 1 can complete braking at a suitable distance.

[0035] See Figure 3 and Figure 5 Furthermore, in this embodiment, the driving assembly 7 includes an electromagnet 72 and a lever 71. One end of the lever 71 can cooperate with the electromagnet 72 (the end has a magnetic portion 711), and the other end of the lever 71 abuts against one end of the push rod 6. The output end of the control module is connected to the electromagnet 72 signal. Under normal conditions, the coil in the electromagnet 72 does not pass current. When the control module sends an action signal to the electromagnet 72, the battery 73 of the electromagnet 72 supplies power to the coil of the electromagnet, attracting one end of the lever 71 to the electromagnet, so that the other end of the lever 71 pushes the push rod 6 to move.

[0036] See Figure 3 and Figure 5 Furthermore, in this embodiment, a spherical abutment portion 712 is provided at one end of the lever 71, and the abutment portion 712 abuts against one end of the push rod 6; the abutment portion 712 is used to abut against the front end surface of the push rod 6. This is conducive to ensuring that when the lever 71 swings toward the electromagnet 72, the abutment portion 712 can effectively transmit the force to the push rod 6. Of course, in other embodiments, the abutment portion 712 can also be other shapes, as long as it can ensure that when the lever 71 swings toward the electromagnet 72, the abutment portion 712 can effectively push the push rod 6.

[0037] See Figure 3 and Figure 5 As a preferred embodiment, the slide 2 is provided with a limiter 9 for limiting the position of the lever 71. This is beneficial to ensure that the magnetic part 711 can be attracted to the electromagnet 72 after the electromagnet 72 is energized. It should be noted that the limiter 9 can be a block, a block or a stopper, as long as it can prevent the magnetic part 711 from continuing to move away from the electromagnet 72.

[0038] See Figures 3 to 8 Furthermore, in the present embodiment, an anti-retraction reset mechanism 8 is provided at one end of the push rod 6 away from the driving assembly 7, and the anti-retraction reset mechanism 8 includes a reset block 83, anti-retraction teeth 81 provided on both sides of the push rod 6, and locking hooks 84 arranged one by one with the anti-retraction teeth 81. A first elastic member 85 is connected between the push rod 6 and the slide seat 2, and a second elastic member 86 is connected between the locking hook 84 and the slide seat 2. A first inclined surface 841 and a second inclined surface 842 are provided on the locking hook 84, the anti-retraction tooth 81 is provided with a third inclined surface 811 cooperating with the first inclined surface 841, and fourth inclined surfaces 831 cooperating with the second inclined surface 842 are provided on both sides of the reset block 83. After the push rod 6 is pushed by the driving assembly 7, the third inclined surface 811 of the anti-retraction tooth 81 will first squeeze the first inclined surface 841 of the lock hook 84, drive the lock hook 84 to move away from the push rod 6, and drive the second elastic member 86 to undergo elastic deformation; then, the anti-retraction tooth 81 moves to the rear of the lock hook 84 and no longer contacts the lock hook 84. Under the action of the restoring force of the second elastic member 86, the lock hook 84 moves toward the push rod 6 to restore its initial position; when the driving assembly 7 no longer pushes the push rod 6, the push rod 6 will have a tendency to reset under the action of the restoring force of the first elastic member 85, and the lock hook 84 will lock the anti-retraction tooth 81, thereby preventing the push rod 6 from retreating and ensuring that the locking pin 4 will not withdraw from the locking hole 11. When the lock pin 4 needs to withdraw from the locking hole 11, the pressing tube 832 can be pressed to drive the reset block 83, so that the fourth inclined surface 831 of the reset block 83 squeezes the second inclined surface 842 of the lock hook 84, and drives the lock hook 84 to move away from the push rod 6. After the anti-retraction tooth 81 is no longer in contact with the anti-retraction tooth 81, the push rod 6 will be reset under the action of the restoring force of the first elastic member 85, and then drive the lock pin 4 to withdraw from the locking hole 11; after the pressing tube 832 is no longer pressed, under the restoring force of the second elastic member 86, the lock hook 84 moves in the direction close to the push rod 6 to restore its initial position, and at the same time, the second inclined surface 842 of the lock hook 84 squeezes the fourth inclined surface 831 of the reset block 83, driving the pressing tube 832 to reset. It should be noted that in this embodiment, when the acceleration data received by the control module for a set time is zero, the control module will send a stop signal to the electromagnet 72 to cut off the power to the coil in the electromagnet 72, so as to facilitate the subsequent reset of the lock pin 4. Of course, in other embodiments, a pressure sensor may also be provided on the pressing tube 832 , and the pressure sensor is connected to the control module signal. When the control module receives the pressure data from the pressure sensor, it sends a stop signal to the electromagnet 72 , and the coil in the electromagnet 72 is de-energized.

[0039] See Figure 3 , Figure 5 and Figure 6Further, in this embodiment, the reset block 83 is connected with a pressing tube 832 to avoid the push rod 6, and the pressing tube 832 is connected with a cap body 833. It is convenient for the operator to press the pressing tube 832 to reset the push rod 6.

[0040] See Figure 3 and Figure 5 Furthermore, in this embodiment, the slide 2 is provided with a first guide member 12 and a second guide member 13 on both sides of the push rod 6. The first guide member 12 is located between the second guide member 13 and the anti-backward tooth 81, and can abut against the anti-backward tooth 81 during the reset process of the push rod 6 to ensure the accuracy of the reset of the push rod 6. A guide channel is formed between the two first guide members 12 and the two second guide members 13, and the push rod 6 is located in the guide channel, which is conducive to ensuring the stability and accuracy of the push rod 6 during movement. The first guide member 12 and the second guide member 13 can be components such as a baffle, a baffle block or a baffle rod.

[0041] See Figures 3 to 7 Furthermore, in this embodiment, a guide plate 82 is provided on the side of the lock hook 84 away from the reset block 83. This is conducive to the lock hook 84 being able to move in the correct direction when the first inclined surface 841 and the second inclined surface 842 are squeezed, and the guide plate 82 can also cooperate with the lock hook 84 to prevent the push rod 6 from retreating.

[0042] See Figure 3 and Figure 5 Furthermore, in the present embodiment, the slide seat 2 is provided with a guide groove 14, and the lock pin 4 is arranged in the guide groove 14, which is beneficial to the stability and accuracy of the lock pin 4 when moving.

[0043] See Figure 2 Furthermore, in this embodiment, both ends of the slide rail 1 are provided with detachable baffles 15. The baffles 15 can prevent the slide seat 2 from escaping from the slide rail 1 at both ends of the slide rail 1. When the slide seat 2 needs to be maintained or replaced, the baffles 15 can be removed to facilitate the removal of the slide seat 2 from the slide rail 1. Preferably, the slide rail 1 is a T-slot rail, and the slide seat 2 is slidably arranged in the T-slot rail, which is conducive to preventing the slide seat 2 from escaping from the slide rail 1 during movement, and has good safety.

[0044] Furthermore, in the present embodiment, the hook 3 is threadedly connected to the slide 2, and a high-strength thread locking agent is applied to the threaded connection, which is beneficial to ensure the connection strength between the hook 3 and the slide 2. Of course, in other embodiments, the hook 3 can also be directly welded to the slide 2.

[0045] Furthermore, in this embodiment, the slide rail 1 is made of aluminum alloy or stainless steel. The surface of the slide rail 1 made of aluminum alloy is anodized, and the surface of the slide rail 1 made of stainless steel is sprayed with an anti-corrosion coating, which has good structural strength and corrosion resistance.

[0046] Furthermore, in this embodiment, the connecting rod 5, the push rod 6, the driving assembly 7 and the anti-retraction reset mechanism 8 are all arranged in the internal space of the slide 2, which can prevent the relevant components from being damaged by contact with the outside during use, thereby improving the service life.

Any technician familiar with the art can make many possible changes and modifications to the technical solution of the present invention by using the technical content disclosed above without departing from the scope of the technical solution of the present invention, or modify it into an equivalent embodiment of equivalent changes.
