Description

Technical Field

[0001] The invention relates to the technical field of high-altitude work safety protection, and is a personal protective equipment for preventing high-altitude workers from falling or sliding, and is a device for protecting and safeguarding the workers, and specifically relates to a toothed disc connector. Background Art

[0002] With the development of my country's economy, there are more and more occasions for aerial work, and the safety and protection of personnel during the operation are becoming more and more important. Therefore, to ensure the safety of operators, relatively safe and reliable protective devices are needed.

[0003] When on-site workers perform mobile operations in areas above 2 meters in height, there is a risk of falling, and they need to be equipped with personal fall protection equipment. At the same time, considering the need for mobile operations, a lifeline protection system needs to be built, and appropriate energy buffering equipment needs to be selected to control the impact of falling and ensure the safety of personnel operations. Therefore, when working at heights, personnel need effective safety protection. At present, workers usually tie the sling around their waists and hang the other end on the connector. However, the current personnel protection relies on fixed connectors, which are inconvenient to use and the moving distance is also limited. Therefore, it is urgent to develop a connector that is easy for people to carry and can be moved. Summary of the invention

[0004] In order to solve the problems existing in the prior art, the present invention provides a toothed disc connector, which is suspended on a stainless steel safety rope at the site when in use, and can move along the stainless steel safety rope. The connector is connected to the operator with a sling, thereby protecting the operator during construction. The connector is easy to use, safe, and easy to carry, avoids potential safety hazards, and solves the safety protection problem during high-altitude operations.

[0005] A toothed disc connector provided by the present invention comprises a connecting toothed disc assembly, a wire rope slider assembly and a connector pull rod assembly;

[0006] The wire rope slider assembly is located at the upper part of the connecting toothed disc assembly and is used to bear the load from the connector pull rod assembly; the arc dovetail groove of the wire rope slider assembly cooperates with the annular dovetail guide rail of the connecting toothed disc assembly. When working, the annular dovetail guide rail of the connecting toothed disc assembly always rotates and slides in the arc dovetail groove of the wire rope slider assembly around the connecting toothed disc core shaft, and the force direction is always inward, so that the connecting toothed disc assembly will not be separated from the wire rope slider assembly;

[0007] The connector pull rod assembly is located at the lower part of the connecting toothed disc assembly and is connected to the connecting toothed disc core shaft of the connecting toothed disc assembly.

[0008] Furthermore, the connecting gear plate assembly has a bilaterally symmetrical structure, including two connecting gear plates, each of which has a plurality of connecting teeth evenly distributed on its inner circumference, the inner side of each connecting tooth is a dovetail structure, and the connecting teeth of each connecting gear plate form the annular dovetail guide rail.

[0009] Furthermore, arc-shaped dovetail grooves are provided on both sides of the wire rope slider assembly, and the two arc-shaped dovetail grooves are respectively matched with the annular dovetail guide rails on both sides.

[0010] Furthermore, the wire rope slider assembly includes a wire rope slider and a wire rope slider pressure cover, the wire rope slider pressure cover is fixedly installed on the wire rope slider by a wire rope slider pressure cover fixing screw, the wire rope slider pressure cover and the wire rope slider cooperate to form an arc-shaped dovetail groove on both sides.

[0011] Furthermore, a wire rope sliding groove is provided at the lower part of the wire rope slider assembly. During operation, the wire rope is located in the wire rope sliding groove, so that the geared disc connector moves along the wire rope.

[0012] Furthermore, a center through hole is provided in the center of each connecting gear disc, and the connecting gear disc is sleeved on the connecting gear disc core shaft through the center through hole, and is connected to the connecting gear disc core shaft through a connecting gear disc fixing washer and a connecting gear disc fixing screw on the outer side of the connecting gear disc, so that the connecting gear disc rotates on the connecting gear disc core shaft.

[0013] Furthermore, each of the connecting toothed discs is correspondingly connected to a connecting toothed disc core shaft, and the other end of each of the connecting toothed disc core shaft is fixedly installed in a mounting hole on the upper part of the connector pull rod assembly.

[0014] Furthermore, the connector pull rod assembly consists of two connector pull rods that can be locked and limited to each other when paired together. When the two connector pull rods are separated, an opening is formed for hanging the toothed disc connector on the wire rope or removing the toothed disc connector hung on the wire rope from the wire rope.

[0015] Furthermore, each of the connector pull rods includes a pull rod body, a connector lock hook, a connector lock hook spring and a connector lock hook fixing pin, a protrusion is provided on one side of the lower part of the pull rod body, the connector lock hook is located in the protrusion, the connector lock hook spring is located inside the connector lock hook, and the connector lock hook spring and the connector lock hook are rotatably mounted on the pull rod body through the connector lock hook fixing pin; one end of the connector lock hook spring abuts against the connector lock hook, and the other end abuts against the protrusion; the lower part of the protrusion is provided with a hook groove for hooking the locking part of the opposite connector lock hook, and a stopper is formed to cooperate with the limiting part of the opposite connector lock hook; a connector lock hook unlocking clamping rod is provided on the outer side of the top of the connector lock hook.

[0016] Furthermore, an arcuate dovetail guide rail is provided on the outer side of each pull rod body, and the arcuate dovetail guide rail cooperates with an annular dovetail groove formed by each connecting tooth of the connecting gear plate.

[0017] During operation, the operator is connected to the connector rod through a sling, and the connector rod drives the integral toothed disc connector to move on the wire rope.

[0018] When the connector is working, the wire rope slider slides on the wire rope. Generally, a U-shaped pull ring needs to be installed every 6 meters to fix the wire rope. When there is no U-shaped pull ring, the connector can move smoothly along the wire rope. When the connector needs to pass through a part with a U-shaped pull ring, if there is no connecting toothed disk and other methods are used for connection, the connector will be blocked at the part of the U-shaped pull ring and cannot move. In order for the connector to move smoothly without being blocked by the U-shaped pull ring, the present invention uses a connecting toothed disk, and avoids the U-shaped pull ring by using the gap between the connecting teeth of the connecting toothed disk. When the connector passes through the U-shaped pull ring, the lower end of the U-shaped pull ring can pass through the gap at the lower end of the wire rope slider, and the parts on both sides of the U-shaped pull ring that contact the connecting teeth of the connecting toothed disk, when passing through the connecting toothed disk, the connecting toothed disk rotates, so that the U-shaped pull ring turns from the gap of a connecting tooth, and the connector completes the action of passing through the U-shaped pull ring. The connecting toothed disc can bypass the U-shaped pull ring by rotating counterclockwise or clockwise. The connector moves to the right, and the connecting toothed disc rotates counterclockwise to pass through the U-shaped pull ring. The connecting toothed disc is pushed to the left by the U-shaped pull ring, and the connecting toothed disc pushed to the left forms a counterclockwise rotation, which enables the connector to pass through the U-shaped pull ring. The connector moves to the left, and the connecting toothed disc rotates clockwise to pass through the U-shaped pull ring. The connecting toothed disc is pushed to the right by the U-shaped pull ring, and the connecting toothed disc pushed to the right forms a clockwise rotation, which enables the connector to pass through the U-shaped pull ring. By rotating the connecting toothed disc, the U-shaped pull ring that fixes the wire rope is avoided, and the connector can pass through the U-shaped pull ring smoothly. In this way, the connector passes through the U-shaped pull ring, and the connector can move unimpeded on the wire rope, which is the main function of the connector.

[0019] The operator carries a sling with him when moving. One end of the sling is connected and fixed to the person's body, and the other end is connected to the connector pull rod, and then the connector is hung on the wire rope. When the person slips, the connector is subjected to force due to the action of the wire rope, which pulls the connector. The connector is connected to the operator's sling, preventing the person from falling. At the same time, the wire rope also has a buffering effect, thereby ensuring the safety of the operator.

[0020] Because it can be moved over long distances, multiple U-shaped pull rings can be used, and generally a U-shaped pull ring is fixed every 6 meters. Each wire rope can be tens or hundreds of meters long, and personnel can work (move) within a range of tens or hundreds of meters, which is very convenient to operate. If a fixed connector is used, the personnel will need to remove the connector every 6 meters they move, and then install it to another location to work, which increases the risk of falling.

[0021] The present invention also provides a high-altitude safety protection device, comprising the geared disc connector described above.

[0022] The advantages and positive effects of the present invention are:

[0023] The toothed disc connector provided by the present invention is easy to use, simple to operate, safe and reliable. During high-altitude operations, the sling hook carried by the personnel is hung on the connector pull rod assembly, and the connector moves on the wire rope. When the connector passes through the portion with the U-shaped pull ring, the connector can be moved unimpeded on the wire rope, thereby avoiding the safety hazards caused by falling or sliding of personnel during high-altitude operations, and ensuring the working safety of high-altitude personnel.

For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0042] like Figures 1 to 8 As shown, a toothed disc connector provided by the present invention includes a connecting toothed disc assembly 200, a wire rope slider assembly 300 and a connector pull rod assembly 100;

[0043] The wire rope slider assembly 300 is located at the upper part of the connecting toothed disc assembly 200, and is used to bear the load from the connector pull rod assembly 100; the arc dovetail groove 304 of the wire rope slider assembly 300 cooperates with the annular dovetail guide rail 2041 of the connecting toothed disc assembly 200. When working, the annular dovetail guide rail 2041 of the connecting toothed disc assembly 200 always rotates and slides in the arc dovetail groove 304 of the wire rope slider assembly 300 around the connecting toothed disc core shaft 205, and the force direction is always inward, so that the connecting toothed disc assembly 200 will not be separated from the wire rope slider assembly 300, ensuring a reliable connection;

[0044] The connector rod assembly 100 is located at the lower part of the connecting toothed disc assembly 200 and is connected to the connecting toothed disc core shaft 205 of the connecting toothed disc assembly 200 .

[0045] The connecting gear disc assembly 200 has a bilaterally symmetrical structure, including two connecting gear discs 203. A plurality of connecting teeth 204 are evenly distributed on the inner circumference of each connecting gear disc 203. The inner side of each connecting tooth 204 is a dovetail structure, and each connecting tooth 204 of each connecting gear disc 203 forms an annular dovetail guide rail 2041.

[0046] The wire rope slider assembly 300 is provided with arc dovetail grooves 304 on both sides, and the two arc dovetail grooves 304 are respectively matched with the annular dovetail guide rails 2041 on both sides.

[0047] Specifically, the wire rope slider assembly 300 includes a wire rope slider 301 and a wire rope slider gland 302. The wire rope slider gland 302 is fixedly mounted on the wire rope slider 301 by a wire rope slider gland fixing screw 303. The wire rope slider gland 302 cooperates with the wire rope slider 301, and an arc dovetail groove 304 is formed on both sides. In order to prevent the annular dovetail guide rail 2041 of the connecting gear plate 203 from being disengaged from the arc dovetail groove 304 of the wire rope slider 301, a wire rope slider gland 302 is fixed on the upper side of the wire rope slider 301 to form an arc dovetail groove 304, which can limit the radial movement of the connecting gear plate 203, so that the connecting gear plate 203 rotates in the arc dovetail groove 304 formed by the wire rope slider 301 and the wire rope slider gland 302.

[0048] A wire rope sliding groove 305 is provided at the lower part of the wire rope slider 301, and a stainless steel safety protection rope (hereinafter referred to as the wire rope) is installed at the work site. During operation, the wire rope 1 is located in the wire rope sliding groove 305, so that the wire rope slider 301 moves along the wire rope 1.

[0049] A center through hole is provided in the center of each connecting toothed disc 203, and each connecting toothed disc 203 is connected to a corresponding connecting toothed disc core shaft 205. The connecting toothed disc 203 is sleeved on the connecting toothed disc core shaft 205 through the center through hole, and is connected to one end of the connecting toothed disc core shaft 205 on the outside of the connecting toothed disc 203 through a connecting toothed disc fixing washer 202 and a connecting toothed disc fixing screw 201. The other end of the connecting toothed disc core shaft 205 is fixedly installed in the mounting hole on the upper part of the connector pull rod assembly 100, so that the connecting toothed disc 203 rotates on an axis centered on the connecting toothed disc core shaft 205. The upper part of the connector pull rod assembly 100 is fixedly connected to one end of the two connecting toothed disc core shafts 205 respectively, the connecting toothed disc 203 is installed in the middle part of the connecting toothed disc core shaft 205, and the outer side of the connecting toothed disc 203 is connected to the other end of the connecting toothed disc core shaft 205 through a connecting toothed disc fixing washer 202 and a connecting toothed disc fixing screw 201, so that the connecting toothed disc 203 can rotate on the connecting toothed disc core shaft 205.

[0050] The connector rod assembly 100 is composed of two connector rods that can be locked and limited to each other after being matched together. Figure 6 As shown, when the two connector rods are separated, an opening is formed for hanging the toothed disc connector on the wire rope or removing the toothed disc connector hung on the wire rope from the wire rope. When working, first open the two connector rods, hang the toothed disc connector on the wire rope, and then close the two connector rods. The toothed disc connector is installed on the wire rope or removed from the wire rope by opening and closing the two connector rods.

[0051] Specifically, each of the connector pull rods includes a pull rod body 101, a connector lock hook 103, a connector lock hook spring 104, and a connector lock hook fixing pin 102. The mounting hole at the upper end of the pull rod body 101 is fixedly connected to the connecting toothed disk core shaft 205. A protrusion 105 is provided on one side of the lower part of the pull rod body 101. The connector lock hook 103 is located in the protrusion 105. The connector lock hook spring 104 is located inside the connector lock hook 103 and passes through the connector lock hook through the connector lock hook fixing pin 102 to lock and position. The hole 1031 allows the connector lock hook spring 104 and the connector lock hook 103 to be rotatably mounted on the pull rod body 101; one end of the connector lock hook spring 104 abuts against the connector lock hook 103, and the other end abuts against the protrusion 105; the lower part of the protrusion 105 is provided with a hook groove 1051 for hooking the locking part 1032 of the opposite connector lock hook, and a stopper 1052 is formed to cooperate with the limiting part 1033 of the opposite connector lock hook; a connector lock hook unlocking and clamping rod 1034 is provided on the outer side of the top of the connector lock hook 103.

[0052] An arcuate dovetail guide rail 106 is disposed on the outer side of each pull rod body 101 , and the arcuate dovetail guide rail 106 cooperates with an annular dovetail groove 2042 formed by each connecting tooth 204 of the connecting toothed disc 203 .

[0053] The connector pull rod assembly 100 is composed of two connector pull rods, each of which has a connector lock hook 103 at the lower part, and a connector lock hook spring 104 inside the connector lock hook 103. When the two connector pull rods are combined together, the two connector lock hooks 103 lock the two connector pull rods with each other under the action of the connector lock hook spring 104, and the connector lock hooks 103 play a positioning and locking role; if you want to open the two connector pull rods, you need to press down the two connector lock hook unlocking and clamping rods, and the two connector pull rods can be opened only after the locking part of the connector lock hook leaves the block of the connector pull rod.

[0054] During operation, the operator is connected to the connector rod assembly 100 via a sling, and the connector rod assembly 100 drives the entire toothed disc connector to move on the wire rope 1 .

[0055] like Fig. 9 and Fig.10As shown, when the toothed disc connector is working, the wire rope slider 301 slides on the wire rope 1. Generally, a U-shaped pull ring 2 needs to be installed every 6 meters to fix the wire rope 1. The U-shaped pull ring 2 is hung on the D-shaped ring 3, and the D-shaped ring 3 is installed on the fixing plate 4. Without the U-shaped pull ring 2, the connector can move smoothly along the wire rope. When the connector needs to pass through a part with a U-shaped pull ring 2, if there is no connecting toothed disc 203 and other methods are used for connection, the connector will be blocked at the part of the U-shaped pull ring 2 and cannot move. In order to ensure that the connector can move smoothly without being blocked by the U-shaped pull ring 2, the present invention uses a connecting toothed disc 203, and utilizes the gap between the connecting teeth of the connecting toothed disc to avoid the U-shaped pull ring 2. When the connector passes through the U-shaped pull ring 2, the lower end of the U-shaped pull ring 2 can pass through the gap at the lower end of the wire rope slider. The two sides of the U-shaped pull ring 2 are in contact with the connecting teeth of the connecting toothed disc. When passing through the connecting toothed disc 203, the connecting toothed disc 203 rotates, so that the U-shaped pull ring 2 turns over a gap of a connecting tooth, and the connector completes the action of passing through the U-shaped pull ring 2. The connecting toothed disc 203 can bypass the U-shaped pull ring 2 by rotating counterclockwise or clockwise. The connector moves to the right, and the connecting toothed disc 203 rotates counterclockwise to pass through the U-shaped pull ring 2. The connecting toothed disc 203 is pushed to the left by the U-shaped pull ring 2, and the connecting toothed disc 203 pushed to the left forms a counterclockwise rotation, and the connector passes through the U-shaped pull ring 2. The connector moves to the left, and the connecting toothed disc 203 rotates clockwise to pass through the U-shaped pull ring 2. The connecting toothed disc 203 is pushed to the right by the U-shaped pull ring 2, and the connecting toothed disc 203 pushed to the right forms a clockwise rotation, and the connector passes through the U-shaped pull ring 2. By rotating the connecting toothed disc 203, the U-shaped pull ring 2 for fixing the steel wire rope is avoided, and the connector can smoothly pass through the U-shaped pull ring 2. Thus, the connector passes through the U-shaped pull ring 2, and the connector can move unimpeded on the steel wire rope 1, which is the main function of the connector.

[0056] The operator carries a sling with him when moving. One end of the sling is connected and fixed to the person's body, and the other end is connected to the connector pull rod assembly 100. The connector is then hung on the wire rope 1. When the person slips, the connector is stressed. Due to the action of the wire rope, the wire rope 1 pulls the connector, and the connector is connected to the operator's sling, so that the operator cannot fall, thereby ensuring the operator's safety.

[0057] Since it can be moved over a long distance, multiple U-shaped pull rings 2 can be used, and generally a U-shaped pull ring 2 is fixed every 6 meters. Each wire rope 1 can be tens of meters or hundreds of meters long, and personnel can work (move) within a range of tens of meters or hundreds of meters, which is very convenient to operate. If a fixed connector is used, the personnel need to remove the connector every 6 meters and then install it to another position to work, which increases the risk of falling.

[0058] The present invention also provides a high-altitude safety protection device, comprising the geared disc connector described above.

[0059] The connector provided by the present invention is easy to use, simple to operate, safe and reliable, and can be moved without obstacles, thereby avoiding potential safety hazards to personnel caused by high-altitude operations.

[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 by equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
