Description

Technical Field

[0001] This invention relates to the field of steel wire rope fixing technology for hydraulic gates, specifically to a rope clamp for fixing the end of a steel wire rope and providing a warning device for rope head slippage. Background Technology

[0002] Steel wire ropes are widely used in the lifting slings of hydraulic gates. The end fixing method is generally to connect the main rope to the rope head with a rope clamp. Whether the connection is firm is related to the safe operation of the gate. During inspections, staff should pay close attention to whether there are any signs of slippage at the rope head. If so, it must be dealt with in time, otherwise it may cause a major accident.

[0003] CN112064596A describes an electrically operated hydraulic gate for water conservancy projects. The gate plate is hoisted and connected to a wire rope on a winch via a lifting ring. However, the wire rope presents several problems during use: the end of the wire rope secured by the rope clamp is often far from the inspection route, or the lighting is poor during nighttime inspections, making it difficult for staff to detect slight slippage of the rope end; additionally, the end of some wire ropes is obstructed by objects, hindering staff observation and making it impossible to promptly assess the rope end's fixation. Similar problems exist in the fixing of wire rope ends in factories and mines during operations. Therefore, there is an urgent need for those skilled in the art to design a rope end slippage warning device for securing the end of the wire rope with a rope clamp. Summary of the Invention

[0004] The problem this invention aims to solve is to provide a rope end slip warning device for securing the end of a wire rope. This device uses a combination of an audible and visual warning component, a clamping spring component, and a pull-down switch component to provide an intuitive audible and visual alarm, prompting workers to take timely countermeasures to prevent rope end slippage and major accidents, thus ensuring the safety of equipment and projects.

[0005] To address the aforementioned problems, this invention provides a rope head sliding warning device for fixing the end of a steel wire rope with a rope clamp, comprising an audible and visual warning component, a clamping spring component, and a pull-down switch component. The audible and visual warning component is disposed on the upper end of the clamping spring component and is rotatably separated from it. One end of the pull-down switch component is fixed to the rope head, and the other end of the pull-down switch component is inserted into the inner end of the clamping spring component through a socket on the clamping spring component. The rope head slides and pulls the pull-down switch component in a linear motion.

[0006] The clamping spring assembly includes a clamping outer shell, a clamping inner shell, a warning light clamping contact spring, a warning sound clamping contact spring, and a waterproof O-ring. The clamping inner shell is fixedly provided on the inner edge of the clamping outer shell. The upper end of the clamping inner shell is provided with threaded protrusions on both sides. A waterproof O-ring is fitted on the outer root of the threaded protrusion. The inner end of the clamping inner shell is provided with at least one set of warning light clamping contact springs and at least one set of warning sound clamping contact springs arranged in a mirror image from top to bottom.

[0007] Preferably, the sound and light warning component includes a sound and light outer shell, a sound and light inner shell, an LED bulb, a sound module, a speaker, and a circular partition. The sound and light inner shell is fixedly installed on the inner edge of the sound and light outer shell. Both the sound and light outer shell and the sound and light inner shell have bulb mounting holes at their upper ends. The LED bulb is installed in the bulb mounting holes. The inner side of the lower end of the sound and light inner shell has a threaded groove. The threaded groove and the threaded protrusion are connected in a rotating and separate manner. The inner end of the sound and light inner shell has a circular partition. The sound module and the speaker are fixed above the circular partition. The diameter of the circular partition is 0.5-1mm smaller than the diameter of the sound and light inner shell. The edge of the circular partition has a square opening to facilitate the insertion of the plug of the clip assembly.

[0008] Preferably, the clamping spring assembly further includes a button battery compartment and a plug. The button battery compartment is fixedly installed on the upper end of the clamping inner shell. One end of the button battery compartment is provided with a plug. The button battery compartment is connected in series with the plug, LED bulb and warning light clamping contact spring through wires to form circuit 1. At the same time, the button battery compartment is connected in series with the plug, sound module and warning sound clamping contact spring through wires to form circuit 2. The speaker is connected in parallel with the sound module through wires to form circuit 3. Circuit 1 is combined with circuit 2 and circuit 3 to form a parallel circuit.

[0009] Preferably, the pull-down switch assembly includes a three-color elastic insulating strip and a mounting base; one end of the three-color elastic insulating strip passes through the socket at the bottom of the spring assembly and extends into the inner end of the clamping inner shell to contact the warning light clamping contact spring and the warning sound clamping contact spring, and one end of the three-color elastic insulating strip is connected to the mounting base.

[0010] Preferably, the three-color elastic insulating strip is marked with equal portions of green, yellow and red elastic insulating strips from bottom to top. The root of the green elastic insulating strip and one end of the mounting base are provided with bolt fixing holes, and bolts pass through the bolt fixing holes to fix the elastic insulating strip to the mounting base.

[0011] Preferably, the LED bulb is an outdoor waterproof bulb.

[0012] Preferably, both the warning light clamping contact spring and the warning sound clamping contact spring are made of tin-phosphor bronze and are integrally molded, which has good resilience and high oxidation resistance.

[0013] Preferably, the acoustic and optical outer shell and the clamping outer shell are both integrally molded from stainless steel, and the acoustic and optical inner shell and the clamping inner shell are both integrally molded from insulating material.

[0014] Preferably, both the clamping housing and the side of the mounting base are equipped with buckles, which are sleeved on the wire rope.

[0015] Preferably, the buckle is a clamp-type structure.

[0016] The advantages of using the above structure are as follows:

[0017] In this invention, one end of a pull-down switch assembly is fixed to the end of a rope, and the other end of the pull-down switch assembly is inserted into the inner end of a clamping spring assembly through a socket. The rope end slides, causing the pull-down switch assembly to move linearly. The pull-down switch assembly includes a three-color elastic insulating strip and a mounting base. One end of the three-color elastic insulating strip passes through the socket at the bottom of the spring assembly and extends into the inner end of the clamping inner shell, contacting the warning light clamping contact spring and the warning sound clamping contact spring. One end of the three-color elastic insulating strip is connected to the mounting base. The pull-down switch assembly is fixed to the end of the wire rope by a buckle on the outside of the base. When the rope end... When slippage occurs due to fixation failure, workers can visually and clearly determine whether the rope end has slipped and the distance it has traveled by observing the length of the green, yellow, and red areas pulled out on the three-color elastic insulating strip. At the same time, the base of the pull-down switch assembly fixed to the rope end also provides some resistance to the rope end slipping off the rope clamp. The installation distance between the clamping spring assembly and the pull-down switch assembly is adjusted to the edge of the green area of ​​the three-color elastic insulating strip. The three-color elastic insulating strip is made of elastic material and has good elasticity, which ensures that even if the rope end and the main rope are not necessarily parallel, it can still be inserted even with deviation.

[0018] The present invention features a rotatingly separable connection between the audible and visual warning component and the clamping spring assembly. The upper end of the clamping inner shell has threaded protrusions on both sides, and the lower end of the audible and visual warning component's inner shell has a threaded groove. The threaded groove and the threaded protrusions on both sides of the upper end of the clamping inner shell of the clamping spring assembly are rotatingly separable, effectively ensuring the stability of the connection between the audible and visual warning component and the clamping spring assembly. This also facilitates installation and disassembly. The clamping spring assembly is fixed to the main wire rope via a snap fastener on its outer shell, and the pull-down switch assembly is fixed to the wire rope end via a snap fastener on the outer side of the base, thus ensuring the overall stability of the device and the wire rope.

[0019] When the rope end slips due to fixation failure, the three-color elastic insulating strip fixed to the rope end is first pulled out through the warning light clamping contact point, activating the warning light circuit and illuminating the red LED bulb to alert personnel. When the three-color elastic insulating strip is then pulled out through the warning sound clamping contact point, the warning sound circuit is activated, and a warning sound is emitted, reminding personnel to take immediate action to prevent the rope end from slipping and causing a major accident, thus ensuring equipment and project safety. When the rope end is in place, the exposed area of ​​the three-color elastic insulating strip is green; when the three-color elastic insulating strip is pulled out through the warning light clamping contact point, the yellow area on the three-color elastic insulating strip begins to be exposed; when the three-color elastic insulating strip is pulled out through the warning sound clamping contact point, the red area on the three-color elastic insulating strip begins to be exposed.

[0025] The present invention will be further explained and described below with reference to the accompanying drawings and embodiments.

[0026] like Figure 1 As shown, the main wire rope 5 and the wire rope head 6 are fixed by a rope clamp 7. The clamping spring assembly 2 of the wire rope head sliding warning device is fixed to the main wire rope 5 by a buckle 4 on the side of the clamping shell 201. The pull-down switch assembly 3 is fixed to the wire rope head by a buckle 4 on the outside of the mounting base 302, thereby ensuring the overall stability of the device and the wire rope.

[0027] like Figure 2As shown, the rope clamp fixing device for the end of the wire rope to prevent slippage includes an audible and visual warning component 1, a clamping spring assembly 2, and a pull-down switch assembly 3. The audible and visual warning component 1 is located on the upper end of the clamping spring assembly 2 and is rotatably separated from it. One end of the pull-down switch assembly 3 is fixed to the rope end, and the other end of the pull-down switch assembly 3 is inserted into the inner end of the clamping spring assembly 2 through a socket. The rope end slides and pulls the pull-down switch assembly 3 to move linearly. Through the cooperation of the audible and visual warning component 1, the clamping spring assembly 2, and the pull-down switch assembly 3, the intuitive audible and visual alarm reminds the staff to take timely countermeasures to avoid serious accidents caused by rope slippage and to ensure the safety of equipment and engineering.

[0028] The clamping spring assembly 2 includes a clamping outer shell 201, a clamping inner shell 202, a warning light clamping contact spring 205, a warning sound clamping contact spring 206, and a waterproof O-ring seal 207. The clamping outer shell 201 is fixedly provided with the clamping inner shell 202 on its inner edge. The upper end of the clamping inner shell 202 is provided with threaded protrusions 208 on both sides. The outer root of the threaded protrusions 208 is fitted with a waterproof O-ring seal 207. The inner end of the clamping inner shell 202 is provided with at least one set of warning light clamping contact springs 205 and at least one set of warning sound clamping contact springs 206 arranged in a mirror image from top to bottom.

[0029] The sound and light warning component 1 includes a sound and light outer shell 101, a sound and light inner shell 102, an LED bulb 103, a sound module 104, a speaker 105, and a circular partition 106. The sound and light inner shell 102 is fixedly mounted on the inner edge of the sound and light outer shell 101. Both the sound and light outer shell 101 and the sound and light inner shell 102 have bulb mounting holes at their upper ends. The LED bulb 103 is mounted in the bulb mounting holes. The inner side of the lower end of the sound and light inner shell 102 has a threaded groove 107. The threaded groove 107 and the threaded protrusion 208 are rotatably separated. The threaded groove 107 and the threaded protrusions on both sides of the upper end of the clamping inner shell 202 of the clamping spring assembly 2 are connected. Part 208 is a rotating and separable connection, which can effectively ensure the fixation of the connection between the sound and light warning component and the clamping spring component, while facilitating installation and disassembly. The clamping spring component is fixed to the main steel wire rope by the buckle on the outer shell, and the pull-down switch component is fixed to the end of the steel wire rope by the buckle on the outside of the base, thereby ensuring the fixation of the whole device and the steel wire rope. The inner end of the sound and light inner shell 102 is provided with a circular partition 106. The sound module 104 and the speaker 105 are fixed above the circular partition 106. The diameter of the circular partition 106 is 0.5-1mm smaller than the diameter of the sound and light inner shell 102, and the edge of the circular partition 106 is provided with a square hole.

[0030] The clamping spring assembly 2 also includes a button battery compartment 203 and a plug 204. The button battery compartment 203 is fixedly installed on the upper end of the clamping inner shell 202. One end of the button battery compartment 203 is provided with a plug 204. Preferably, the clamping spring assembly also includes a button battery compartment and a plug. The button battery compartment 203 is fixedly installed on the upper end of the clamping inner shell. One end of the button battery compartment is provided with a plug. The button battery compartment 203 is connected in series with the plug 204, the LED bulb 103 and the warning light clamping contact spring 205 through wires to form a circuit 1. At the same time, the button battery compartment 203 is connected in series with the plug 204, the sound module 104 and the warning sound clamping contact spring 206 through wires to form a circuit 2. The speaker 105 is connected in parallel with the sound module 104 through wires to form a circuit 3. Circuit 1 is combined with circuit 2 and circuit 3 to form a parallel circuit.

[0031] The pull-down switch assembly includes a three-color elastic insulating strip 301 and a mounting base 302; one end of the three-color elastic insulating strip 301 passes through the insertion port at the bottom of the spring assembly 2 and extends into the inner end of the clamping inner shell 202 to contact the warning light clamping contact spring 205 and the warning sound clamping contact spring 206, and one end of the three-color elastic insulating strip 301 is connected to the mounting base 302.

[0032] like Figure 3 As shown, the three-color elastic insulating strip 301 is marked with equal divisions of green elastic insulating strip 301-1, yellow elastic insulating strip 301-2 and red elastic insulating strip 301-3 from bottom to top. The root of the green elastic insulating strip 301-1 and one end of the mounting base 302 are provided with bolt fixing holes. The bolt passes through the bolt fixing holes to fix the elastic insulating strip 301-1 to the mounting base 302. When the rope head slips due to fixation failure, the staff can intuitively and clearly judge whether the rope head has slipped and the distance after slipping by the length of the green, yellow and red areas pulled out on the three-color elastic insulating strip 301-1. At the same time, the mounting base 302 of the pull-down switch assembly 3 fixed to the rope head also has a certain blocking effect on the rope head slipping from the rope clamp. The installation distance between the clamping spring assembly 2 and the pull-down switch assembly 3 is adjusted to the edge of the green area of ​​the three-color elastic insulating strip 301. The three-color elastic insulating strip is made of elastic material and has good elasticity, so that even if the rope head and the main rope are not necessarily parallel, it can still be inserted even if there is a deviation.

[0033] When the rope end slips due to fixation failure, the three-color elastic insulating strip fixed to the rope end is first pulled out at the warning light clamp contact point, activating the warning light circuit and illuminating the red LED bulb to alert personnel. When the three-color elastic insulating strip is then pulled out at the warning sound clamp contact point, the warning sound circuit is activated, and the horn emits a warning sound, reminding personnel to take immediate action to prevent the rope end from slipping and causing a major accident, ensuring equipment and project safety. When the rope end is in place, the exposed area of ​​the three-color elastic insulating strip is green; when the three-color elastic insulating strip is pulled out at the warning light clamp contact point, the yellow area on the three-color elastic insulating strip begins to be exposed; when the three-color elastic insulating strip is pulled out at the warning sound clamp contact point, the red area on the three-color elastic insulating strip begins to be exposed.

[0034] The LED bulb 101 is an outdoor waterproof bulb, and the warning light clamping contact spring 205 and the warning sound clamping contact spring 206 are both made of tin phosphor bronze as an integral structure.

[0035] The acoustic and light outer shell 101 and the clamping outer shell 201 are both made of stainless steel casting as an integral structure, and the acoustic and light inner shell 102 and the clamping inner shell 202 are both made of insulating material injection molding as an integral structure.

[0036] Both the clamping housing 201 and the mounting base 302 are equipped with buckles 4 on their sides. The buckles 4 are sleeved on the steel wire rope 5 and are clamp-type structures.

[0037] To facilitate understanding of the above technical solutions of the present invention, the following detailed description of the above technical solutions of the present invention will be provided through specific usage methods.

[0038] The specific working process is as follows: In order to facilitate understanding of the above technical solution of the present invention, the above technical solution of the present invention will be described in detail below through specific usage methods.

[0039] The specific usage is as follows: The LED bulb 103 protrudes from the top of the inner shell 102 of the sound and light warning component 1. Below the bulb is a circular partition 106 with a diameter 1mm smaller than the inner shell diameter. The sound module 104 and speaker 105 are fixed above the circular partition 106. The edge of the circular partition 106 has a square opening. Inside the inner shell 202 of the clamping spring assembly 2, there is a set of warning light clamping spring contacts 205 at the top and a set of warning sound clamping spring contacts 206 at the bottom. A button battery compartment 203 is located on the outer top of the clamping inner shell 202. A plug 204 passes through the square opening on the edge of the circular partition, connecting the battery in the button battery compartment 203 to the sound module 104, speaker 105, and LED bulb 103 of the sound and light warning component 1. Together with the warning light clamping spring contacts 205 and the warning sound clamping spring contacts 206, they form a parallel circuit. The sound and light warning component and the clamping spring assembly are connected via... The threaded connection is integrated into one unit. The waterproof O-ring 207 at the root of the threaded protrusion 208 prevents external rainwater from seeping in. The assembled component is fixed to the main wire rope by the clips 4 of the clamping shell 201 of the clamping spring assembly 2. The pull-down switch assembly 3 is fixed to the end of the wire rope by the clips 4 on the outside of the mounting base 302. The three-color elastic insulating strip 301 is inserted from the bottom socket of the clamping spring assembly between the clamping spring contacts of the warning light and warning sound. Since the rope end and the main rope may not be parallel, the three-color elastic insulating strip is made of elastic material to ensure insertion even with deviation. The installation distance between the clamping spring assembly and the pull-down switch assembly is adjusted to the edge of the green area of ​​the three-color elastic insulating strip.

[0040] When the rope end begins to slide downwards in a straight line due to fixation failure, the yellow elastic insulating strip 301-2 of the tri-color elastic insulating strip 301 fixed to the rope end is pulled out first, causing the warning light clamping contact 205 to be pulled out. The two warning light clamping contact springs 205, which were originally separated by the tri-color elastic insulating strip, immediately close under the elastic action. The button battery compartment 203, plug 204, LED bulb 103 and warning light clamping contact spring 205 connected by wires are connected in series, and the LED bulb 103 lights up to warn the staff. If the potential for rope end fixation failure is not addressed promptly, the rope end will continue to slide downwards in a straight line under stress. The red elastic insulating strip 301-3 of the three-color elastic insulating strip fixed to the rope end will be pulled out again, triggering the warning sound clamping contact spring. The two warning sound clamping contact springs 206, which were originally separated by the three-color elastic insulating strip, will immediately close under the elastic action. The button battery compartment 203, plug 204, sound module 104, and warning sound clamping contact spring 206 connected in series through the wire will be connected in a circuit. The speaker 105 connected in parallel to the sound module 104 will emit a warning sound, reminding the staff to take immediate measures to prevent the rope end from slipping and causing a major accident, thus ensuring the safety of equipment and the project.

[0041] When the rope end is stationary, the exposed area of ​​the three-color elastic insulating strip is green. When the three-color elastic insulating strip is pulled out to activate the warning light and clamp the contact spring, the yellow area on the three-color elastic insulating strip begins to be exposed. When the insulating strip is pulled out to activate the warning sound and clamp the contact spring, the red area on the three-color elastic insulating strip begins to be exposed. Even if the audible and visual warning components and the clamping spring components malfunction, workers can visually and clearly determine whether the rope end has slipped and the distance it has traveled by observing the length of the green, yellow, and red areas pulled out of the three-color elastic insulating strip. In addition, the base of the pull-down switch component fixed to the rope end also provides some resistance to the rope end slipping off the rope clamp.
