Metal wire strength detection device based on stone cage net processing

Abstract

This invention provides a metal wire strength testing device based on gabion mesh processing, belonging to the field of metal wire strength testing technology. It includes: a testing platform, with a front protective baffle rotatably mounted on its front end face, the top surface of the front protective baffle being lower than the top surface of the testing platform; and a rear protective baffle rotatably mounted on its rear end face, the top surface of the rear protective baffle being higher than the top surface of the front protective baffle. Through a mechanical linkage structure of the rear protective baffle, the obstructing rod, and the front protective baffle, a unique protective closing operation sequence is defined. The operator must sequentially close the rear protective baffle, slide the obstructing rod, and close the front protective baffle to expose the motor control switch and start the test. This solves the problem that traditional wire stretching equipment often uses simple side baffles without a forced protective linkage mechanism, and the closing of the protective baffle relies on manual subjective operation, easily resulting in situations where only one side is closed or the equipment is started without closing, posing a significant safety hazard.

Description

Technical Field

[0001] This invention relates to the field of metal wire strength testing technology, and in particular to a metal wire strength testing device based on gabion mesh processing. Background Technology

[0002] Gabion mesh, also known as gabion baskets, is widely used in municipal and civil engineering fields such as water conservancy and flood control, slope reinforcement, roadbed protection, and river regulation due to its excellent erosion resistance, settlement resistance, and permeability. The structural stability and service life of gabion mesh are directly determined by the physical properties of the metal wire used in its processing. Tensile strength, as a core performance indicator of the metal wire, is crucial for quality control in gabion mesh production. Therefore, accurate and standardized tensile strength testing of the metal wire is an essential procedure in the gabion mesh processing stage and an important basis for project quality acceptance.

[0003] Currently, the industry mostly uses general-purpose wire tensile testing equipment to test the strength of metal wire used in gabion mesh processing. However, the protective structure of traditional wire tensile testing equipment is mostly a simple side baffle design. Existing equipment does not have any forced protective linkage mechanism. The closing of the protective plate depends entirely on the subjective operation of the operator. In actual operation, operators often start the test by closing only one side of the protective plate or even not closing the protective plate, which greatly increases the probability of injury during operation. Summary of the Invention

[0004] This invention relates to a metal wire strength testing device based on gabion mesh processing. It solves the problem that traditional wire stretching equipment often uses simple side baffles for protection, lacks a forced protection linkage mechanism, and the closure of the protective plate depends on manual subjective operation. This can easily lead to situations where the equipment is started even if only one side is closed or not closed, posing a significant safety hazard.

[0005] This invention provides a wire strength testing device based on gabion mesh processing, specifically comprising: a testing platform, a front protective baffle rotatably mounted on the front end face of the testing platform, the top surface of the front protective baffle being lower than the top surface of the testing platform; a rear protective baffle rotatably mounted on the rear end face of the testing platform, the top surface of the rear protective baffle being higher than the top surface of the front protective baffle; a sliding cavity is formed inside the testing platform, and a sliding hole penetrating the front and rear ends of the testing platform is formed at the axial center of the sliding cavity; the sliding hole is lower than the top surface of the rear protective baffle but higher than the top surface of the front protective baffle; the sliding hole contains... A sliding insertion is provided with a blocking rod. A front annular block and a rear annular block are fixedly installed on the front and rear sides of the outer periphery of the blocking rod, respectively. The front and rear annular blocks are slidably installed inside the sliding cavity. When the front end face of the front annular block contacts the front side of the inner end of the sliding cavity, the rear end face of the blocking rod is in the same vertical plane as the rear end face of the detection platform, and the front end of the blocking rod protrudes from the front opening end of the insertion sliding hole. When the rear end face of the rear annular block contacts the rear side of the inner end of the sliding cavity, the front end face of the blocking rod is in the same vertical plane as the front end face of the detection platform, and the rear end of the blocking rod protrudes from the rear opening end of the insertion sliding hole.

[0006] Furthermore, the top surface of the testing platform is symmetrically equipped with two side blocks, the front and rear faces of which are respectively on the same vertical plane as the front and rear faces of the testing platform. Each of the two side blocks has a locking groove on its front and rear sides. Two front locking components are fixedly installed at the bottom of the front face of the front protective baffle. When the front protective baffle is flipped upwards and its front face contacts the front faces of the two side blocks, the two front locking components engage with the two locking grooves located on the front side. Similarly, two rear locking components are fixedly installed at the bottom of the rear face of the rear protective baffle. When the rear protective baffle is flipped upwards and its rear face contacts the rear faces of the two side blocks, the two rear locking components engage with the two locking grooves located on the rear side.

[0007] Furthermore, a piece of explosion-proof glass is embedded between the front end face and the rear end face of the front protective baffle; when the front end face of the front protective baffle is in contact with the front end face of the two side baffles, the position area between the explosion-proof glass and the two side baffles corresponds.

[0008] Furthermore, a reciprocating moving groove is provided on the opposite surface of each of the two side blocks. A ball screw is rotatably installed in the reciprocating moving groove on the right side via a bearing. A motor is fixedly installed on the top surface of the side block on the right side, and the shaft end of the motor is fixedly connected to the screw in the ball screw. A guide limit post is fixedly installed in the reciprocating moving groove on the left side.

[0009] Furthermore, a reciprocating moving block is slidably installed between the two reciprocating moving slots. A guide limiting sliding hole is opened on the left side of the top surface of the reciprocating moving block, penetrating its bottom surface. The guide limiting sliding hole is slidably inserted into the guide limiting post. A mounting hole is opened on the right side of the top surface of the reciprocating moving block, penetrating its bottom surface. The nut in the ball screw is fixedly connected to the mounting hole.

[0010] Furthermore, a set of wire clamps is fixedly installed on the bottom surface of the reciprocating moving block via a tension sensor; a set of wire clamps is also fixedly installed on the top surface of the detection platform, with the two sets of wire clamps corresponding to each other.

[0011] Furthermore, a control slot is provided on the front end face of the testing platform, and a motor forward rotation control switch and a motor reverse rotation control switch are installed inside the control slot.

[0012] Furthermore, when the front protective baffle is in its natural hanging state, the front protective baffle covers and blocks the control slot; when the front end face of the front protective baffle is in contact with the front end faces of the two side blocks, the control slot is exposed.

[0013] This invention provides a metal wire strength testing device based on gabion mesh processing, which has the following beneficial effects: This invention, through the mechanical linkage structure of the rear protective baffle, the obstruction rod, and the front protective baffle, defines a unique protective closing sequence. Operators must sequentially close the rear protective baffle, slide the obstruction rod, and close the front protective baffle before exposing the motor control switch and starting the test. This completely eliminates the non-standard operation of traditional equipment where testing is started without protection or with only one side protection. At the same time, the protective baffles on the front and rear sides of the testing platform, together with the side blocks, achieve full circumference enclosure of the testing area, solving the problem of traditional wire stretching machines being open at the front and back, where metal wires easily bounce back and forth and injure people when broken. The explosion-proof glass embedded in the front protective baffle not only enables real-time visual observation of the testing process but also resists the impact of flying metal wires, further improving protective safety.

[0014] This invention employs a dual-track drive structure consisting of a ball screw and a guide limit post, enabling the reciprocating moving block to perform a smooth linear lifting and lowering motion along the reciprocating moving groove. This ensures that the tensile force applied to the metal wire is uniform and without deviation, avoiding detection errors caused by shaking during the stretching process. A tension sensor is installed between the reciprocating moving block and the metal wire clamp, which can collect tensile data in real time and accurately collect tensile data during the stretching process, and accurately record the ultimate tensile force value when the metal wire breaks. This provides a precise quantitative basis for determining the tensile strength of the metal wire used in gabion mesh processing, meeting the testing standards of industrial production.

[0019] Example: Please refer to Figures 1 to 9 : This invention proposes a wire strength testing device based on gabion mesh processing, comprising: a testing platform 1, a front protective baffle 2 rotatably mounted on the front end face of the testing platform 1, the top surface of the front protective baffle 2 being lower than the top surface of the testing platform 1; a rear protective baffle 4 rotatably mounted on the rear end face of the testing platform 1, the top surface of the rear protective baffle 4 being higher than the top surface of the front protective baffle 2; a sliding cavity 1013 is formed inside the testing platform 1, and an insertion sliding hole 1012 penetrating the front and rear ends of the testing platform 1 is formed at the axial center of the sliding cavity 1013; the insertion sliding hole 1012 is lower than the top surface of the rear protective baffle 4 but higher than the top surface of the front protective baffle 2; insertion... A blocking rod 3 is slidably inserted into the sliding hole 1012. A front annular stop 301 and a rear annular stop 302 are fixedly installed on the front and rear sides of the outer periphery of the blocking rod 3, respectively. The front annular stop 301 and the rear annular stop 302 are slidably installed inside the sliding cavity 1013. When the front end face of the front annular stop 301 contacts the front side of the inner end of the sliding cavity 1013, the rear end face of the blocking rod 3 is on the same vertical plane as the rear end face of the detection table 1, and the front end of the blocking rod 3 protrudes from the front opening end of the sliding hole 1012. When the rear end face of the rear annular stop 302 contacts the rear side of the inner end of the sliding cavity 1013, the front end face of the blocking rod 3... The front face of the testing platform 1 is on the same vertical plane as the front face of the testing platform 1, while the rear end of the obstructing rod 3 protrudes from the rear opening end of the insertion sliding hole 1012; two side blocking blocks 101 are fixedly installed on the top face of the testing platform 1 in a symmetrical manner, and the front and rear faces of the side blocking blocks 101 are respectively on the same vertical plane as the front and rear faces of the testing platform 1; a snap-fit ​​groove 105 is opened on the front and rear sides of the top face of the two side blocking blocks 101; two front snap-fit ​​pieces 202 are fixedly installed at the bottom of the front face of the front protective baffle 2. When the front protective baffle 2 is flipped upward and its front face is in contact with the front face of the two side blocking blocks 101, the two front snap-fit ​​pieces 202... 02 respectively engages with the two latching slots 105 located on the front side; two rear latching pieces 401 are fixedly installed at the bottom of the rear end face of the rear protective baffle 4. When the rear protective baffle 4 is flipped upward and its rear end face is in contact with the rear end face of the two side blocking blocks 101, the two rear latching pieces 401 respectively engage with the two latching slots 105 located on the rear side; a piece of explosion-proof glass 201 is embedded between the front end face and the rear end face of the front protective baffle 2; when the front end face of the front protective baffle 2 is in contact with the front end face of the two side blocking blocks 101, the position area between the explosion-proof glass 201 and the two side blocking blocks 101 corresponds.

[0020] Each of the two side stop blocks 101 has a reciprocating groove 102 on its opposite surface. A ball screw 103 is rotatably mounted in the right reciprocating groove 102 via a bearing. A motor 104 is fixedly mounted on the top surface of the right side stop block 101, and the shaft end of the motor 104 is fixedly connected to the screw in the ball screw 103. A guide limit post 108 is fixedly mounted in the left reciprocating groove 102. A reciprocating block 107 is slidably mounted between the two reciprocating grooves 102. A guide limiting sliding hole 1010 is provided on the left side, penetrating its bottom end face. The guide limiting sliding hole 1010 is slidably inserted into the guide limiting post 108. A mounting hole 1011 is provided on the right side of the top surface of the reciprocating moving block 107, penetrating its bottom end face. The nut in the ball screw 103 is fixedly connected to the mounting hole 1011. A set of wire clamps 106 is fixedly installed on the bottom end face of the reciprocating moving block 107 through a tension sensor 109. A set of wire clamps 106 is also fixedly installed on the top surface of the detection table 1. The two sets of wire clamps 106 are positioned correspondingly.

[0021] The front face of the testing platform 1 is provided with a control slot 1014, and the control slot 1014 is equipped with a motor forward rotation control switch 1015 and a motor reverse rotation control switch 1016. When the front side protective baffle 2 is in a natural hanging state, the front side protective baffle 2 covers and blocks the control slot 1014. When the front face of the front side protective baffle 2 is in contact with the front face of the two side blocks 101, the control slot 1014 is exposed.

[0022] The working principle of this embodiment: The principle of the forced linkage protection of this device is as follows: This device uses a mechanical linkage mechanism to enforce the requirement that the front and rear protective plates must close in a fixed sequence before the motor control switch can be activated for start-up detection. This fundamentally avoids the operational risks associated with unprotected or one-sided protection. The core linkage logic is as follows: The forward rotation control switch 1015 and the reverse rotation control switch 1016 of the motor 104 are integrated in the control slot 1014 at the front end of the test bench 1. When the front protective baffle 2 hangs down naturally, it will completely cover the control slot 1014, and the operator cannot touch or operate the switch. Only after the front protective baffle 2 is flipped up and attached to the side block 101 will the control slot 1014 be fully exposed. This is the basic premise for starting the test. The upward flipping action of the front protective baffle 2 is restricted by the obstruction rod 3. The obstruction rod 3 is slidably inserted into the insertion sliding hole 1012 of the detection table 1. In its natural state, the front annular block 301 is in contact with the front inner wall of the sliding cavity 1013. The front end of the obstruction rod 3 protrudes from the front opening end of the insertion sliding hole 1012, directly blocking the flipping path of the front protective baffle 2. The front end of the obstruction rod 3 must be completely pressed into the insertion sliding hole 1012 to release the obstruction of the front protective baffle 2. The forward and backward sliding motion of the obstruction rod 3 is restricted by the rear protective baffle 4. The rear opening end of the insertion sliding hole 1012 is completely blocked when the rear protective baffle 4 hangs down naturally, so the rear end of the obstruction rod 3 cannot move backward, and thus cannot press the front end into the insertion sliding hole 1012. Only when the rear protective baffle 4 is flipped upward and attached to the side block 101 will the rear opening end of the insertion sliding hole 1012 be exposed, and the obstruction rod 3 can slide freely.

[0023] In summary, operators must complete the protective operation in a fixed sequence of "closing the rear protective baffle 4, sliding the obstruction rod 3, and closing the front protective baffle 2" before they can contact the motor control switch. This achieves forced synchronous closure of the front and rear protective plates, completely eliminating the safety hazards of unprotected or single-sided detection. The specific process of the protective linkage logic and tensile testing of this device is as follows: The operator clamps the two ends of the wire mesh to be tested at the two sets of wire clamps 106 at the top of the testing table 1, ensuring that the wire mesh is taut. Flip the rear protective baffle 4 of the rear end face of the detection table 1 upward so that its rear end face is in contact with the rear end face of the two side block bodies 101. At this time, the two rear side fasteners 401 at the bottom of the rear protective baffle 4 are engaged with the fastener grooves 105 on the rear side of the side block body 101 to fix the rear protective baffle 4. At the same time, the rear opening end of the insertion sliding hole 1012 is exposed, and the restriction on the sliding of the obstruction rod 3 is released. Push the obstruction rod 3 backward so that the front annular block 301 contacts the rear inner wall of the sliding cavity 1013. The front end of the obstruction rod 3 is fully pressed into the insertion sliding hole 1012, and the rear end protrudes from the rear opening end of the insertion sliding hole 1012, thus completely removing the obstruction rod 3 from the path of the front protective baffle 2 to flip. Flip the front protective baffle 2 of the front end face of the testing table 1 upward so that its front end face is in contact with the front end face of the two side blocks 101. At this time, the two front fasteners 202 at the bottom of the front protective baffle 2 are engaged with the fastener slots 105 on the front side of the side blocks 101 to fix the front protective baffle 2. In this state, the front and rear sides of the testing table 1 are closed by the protective plate, and the control slot 1014 is fully exposed. The operator can check the tension status of the testing area in real time through the explosion-proof glass 201 on the front protective baffle 2. The operator presses the motor forward rotation control switch 1015 in the control slot 1014, the motor 104 starts and drives the ball screw 103 to rotate forward, the nut drives the reciprocating moving block 107 to move upward smoothly along the reciprocating moving slot 102, the upper metal wire clamp 106 moves upward with the reciprocating moving block 107, applying a continuous tensile force to the metal wire, and the tension sensor 109 synchronously collects the tension data in real time; When the metal wire is broken, the tension sensor 109 records the ultimate tensile force value during the stretching process, which is the tensile strength of the metal wire. After the metal wire is broken, the operator presses the motor reverse control switch 1016, and the motor 104 drives the ball screw 103 to reverse, so that the reciprocating moving block 107 is reset to the initial position. Flip the front protective baffle 2 downwards in sequence, push the obstruction rod 3 forward, and flip the rear protective baffle 4 downwards to restore all components to their natural hanging / initial state. Remove the broken metal wire, re-clamp the new metal wire to be tested, and repeat the above steps to perform continuous metal wire strength testing.
