Abstract
Description
Technical Field
[0001] This application relates to the field of steel strand, specifically a steel strand tensile testing and positioning device. Background Technology
[0002] Steel strand is a steel product made of multiple steel wires twisted together. It is often used as the main load-bearing component in building structures, power facilities and other load-bearing structures. In order to ensure that the strength of the steel strand meets the requirements, it is necessary to perform tensile testing on the steel strand before use.
[0003] Utility model patent CN221260658U discloses a steel wire rope strength testing device with an anti-loosening structure. The device includes a worktable with two symmetrically sliding movable seats on its top. A drive assembly on the worktable controls the two movable seats to move closer or further apart. Each movable seat has a clamping assembly inside. The clamping assembly includes a box hinged to the movable seat, with two clamping members symmetrically sliding inside the box. By configuring the movable seats, drive assembly, clamping assembly, and linkage assembly, the device facilitates the placement and removal of the steel wire rope between adjacent clamping members, effectively ensuring the testing efficiency. Furthermore, when stretching or relaxing the steel wire rope, the adjacent clamping members maintain a tight clamping state, simulating the real-world scenario of steel wire rope use and effectively ensuring the accuracy of the steel wire rope testing.
[0004] The device is equipped with a workbench, on which are mounted movable seats and drive components. During tensile testing, the operator places the wire rope between two clamping components. Then, as the two movable seats move away from each other, the gears and racks engage to clamp the wire rope. However, if the wire rope breaks during the test, metal shavings are easily scattered everywhere, making it inconvenient for the operator to clean up the scattered metal shavings. Utility Model Content
[0005] To address the problem of inconvenient metal shavings removal in existing technologies, this utility model provides a steel strand tensile testing and positioning device.
[0006] Therefore, the specific technical solution adopted by this utility model is as follows:
[0007] This utility model provides a steel strand tensile testing and positioning device, including a base, a placement plate fixedly mounted on the base, a groove on the placement plate, a collection cavity inside the placement plate, a collection hole at the bottom of the groove communicating with the collection cavity, a through hole on the outer side of the placement plate communicating with the collection cavity, a collection frame slidably mounted in the through hole, a ventilation hole on the base communicating with the collection cavity, a fan mounted in the ventilation hole, the bottom of the collection frame aligned with the ventilation hole, a filter hole at the bottom of the collection frame, a mounting base one fixedly mounted at one end of the placement plate, a mounting base two slidably mounted at the other end of the placement plate, clamps slidably mounted on the top of both mounting base one and mounting base two, a countersunk hole at the end of the placement plate near mounting base two, an electric push rod fixedly mounted in the countersunk hole, a pressure sensor fixedly mounted on mounting base two aligned with the output shaft of the electric push rod, an adjustment mechanism on both mounting base one and mounting base two, and a protective mechanism on the placement plate.
[0008] Preferably, the adjustment mechanism includes a motor, a screw, and a fixed frame. Both mounting base one and mounting base two have a sliding groove at their bottoms. The fixed frame is slidably disposed within the sliding groove, with its top fixedly connected to a clamping plate. The bottom of the sliding groove has a mounting cavity, where the motor is fixedly disposed. The screw is located within the sliding groove and rotatably connected to the inner wall of the groove. The motor output shaft is drively connected to one end of the screw. The fixed frame is fitted onto the screw. When the operator starts the motor in the mounting cavity, the motor drives the screw to rotate, thereby causing the fixed frame and clamping plate to slide vertically, thus achieving the clamping operation of the steel strands on mounting base one and mounting base two. This makes the operation convenient.
[0009] Preferably, the protective mechanism includes a protective cover, which is rotatably mounted on the top of the shelf. After the worker places the steel strand on the shelf and clamps it, the protective cover can be rotated and lowered along the shelf to shield the steel strand on the shelf, preventing it from swinging when it breaks due to tension. It can also shield the generated metal shavings, allowing them to fall into the collection box below, thus improving the safety of the worker.
[0010] Preferably, the protective cover is transparent, which makes it easy for staff to observe the condition of the steel strands on the shelf and facilitates operation.
[0011] Preferably, the mounting base one, mounting base two, and clamping plate are all provided with arc-shaped grooves. The arc-shaped grooves allow the clamping plate to increase the contact area with the steel strand when clamping it, thus ensuring the stability of the clamping.
[0012] Preferably, the second mounting base is fixedly provided with a plug rod, and the placement plate is provided with a plug hole that matches the plug rod. The plug rod and the plug hole are used to initially limit the sliding of the second mounting base, so as to ensure the stability of the sliding of the second mounting base.
[0013] Preferably, a control terminal is fixedly installed on the base. The motor, fan, and electric push rod are all electrically connected to the control terminal through wires. The operator can conveniently adjust the working status of the motor, fan, and electric push rod through the control terminal, making operation convenient.
[0014] The advantages of adopting the above technical solution are:
[0015] This invention includes a base with a shelf fixedly mounted on it. The shelf has a groove and a collection chamber inside. The bottom of the groove has a collection hole communicating with the collection chamber. The outer side of the shelf has a through hole communicating with the collection chamber, and a collection frame is slidably mounted inside the through hole. The base has a ventilation hole communicating with the collection chamber, and a fan is installed inside the ventilation hole. The bottom of the collection frame is aligned with the ventilation hole, and a filter hole is provided at the bottom of the collection frame. In this device, by providing a collection chamber inside the shelf, when the steel strand breaks due to tension, the fan inside the ventilation hole can suck up the metal shavings generated on the shelf and collect them into the collection frame inside the collection chamber, thus facilitating the cleaning of metal shavings.

Detailed Implementation
[0022] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0023] like Figure 1-4 As shown in the figure, this utility model discloses a steel strand tensile testing and positioning device, including a base 1, a placement plate 2 fixedly mounted on the base 1, a groove 201 provided on the placement plate 2, a collection cavity 200 provided inside the placement plate 2, a collection hole 210 communicating with the collection cavity 200 at the bottom of the groove 201, a through hole communicating with the collection cavity 200 on the outer side of the placement plate 2, a collection frame 220 slidably disposed in the through hole, a ventilation hole 100 communicating with the collection cavity 200 on the base 1, a fan disposed in the ventilation hole 100, and the bottom of the collection frame 220 aligned with the ventilation. The bottom of the collection frame 220 is provided with filter holes. One end of the shelf 2 is fixedly provided with mounting base 3, and the other end of the shelf 2 is slidably provided with mounting base 4. The top of mounting base 3 and mounting base 4 are both slidably provided with clamping plates 5. The end of the shelf 2 near mounting base 4 is provided with a countersunk hole, and an electric push rod 8 is fixedly provided in the countersunk hole. A pressure sensor 801 aligned with the output shaft of the electric push rod 8 is fixedly provided on mounting base 4. Both mounting base 3 and mounting base 4 are provided with adjustment mechanisms, and the shelf 2 is provided with a protective mechanism.
[0024] In at least one embodiment, the adjusting mechanism includes a motor, a screw 7, and a fixing frame 6. Both mounting base 1 (3) and mounting base 2 (4) have a sliding groove 301 at their bottoms. The fixing frame 6 is slidably disposed within the sliding groove 301. The top of the fixing frame 6 is fixedly connected to the clamping plate 5. The bottom of the sliding groove 301 has an installation cavity. The motor is fixedly disposed within the installation cavity. The screw 7 is located within the sliding groove 301 and rotatably connected to the inner wall of the sliding groove 301. The motor output shaft is drively connected to one end of the screw 7. The fixing frame 6 is fitted onto the screw 7. When the operator starts the motor in the installation cavity, the motor drives the screw 7 to rotate, thereby causing the fixing frame 6 and the clamping plate 5 to slide vertically, thus achieving the clamping operation of the steel strands on mounting base 1 (3) and mounting base 2 (4). The operation is convenient.
[0025] In at least one embodiment, the protective mechanism includes a protective cover 9, which is rotatably mounted on the top of the shelf 2. After the worker places the steel strand on the shelf 2 and clamps it, the protective cover 9 can be rotated down along the shelf 2 to shield the steel strand on the shelf 2, preventing the steel strand from swinging when it breaks due to tension. It can also shield the generated metal shavings so that they can fall into the collection box 200 below, thereby improving the safety of the worker.
[0026] In at least one embodiment, the protective cover 9 is transparent, which makes it easy for staff to observe the condition of the steel strands on the shelf 2 and facilitates operation.
[0027] In at least one embodiment, the mounting base 3, the mounting base 4, and the clamping plate 5 are all provided with arc-shaped grooves 302. The arc-shaped grooves 302 enable the clamping plate 5 to increase the contact area with the steel strand when clamping the steel strand, thereby ensuring the stability of the clamping.
[0028] In at least one embodiment, a plug rod 401 is fixedly provided on the mounting base 2 4, and a socket is provided on the shelf 2 to fit the plug rod 401. The plug rod 401 and the socket are used to initially limit the sliding of the mounting base 2 4, so as to ensure the stability of the sliding of the mounting base 2 4.
[0029] In at least one embodiment, a control terminal is fixedly installed on the base 1. The motor, fan, and electric push rod 8 are all electrically connected to the control terminal through wires. The operator can conveniently adjust the working status of the motor, fan, and electric push rod 8 through the control terminal, making the operation convenient.
[0030] During the tensile testing of steel strands, the operator places the steel strand to be tested on the placement plate 2 on the base 1. The groove 201 on the placement plate 2 provides initial positioning of the steel strand, keeping it straight. Then, the two ends of the steel strand are placed on mounting base 3 and mounting base 4 respectively. The operator then uses an adjustment mechanism to lower the clamping plates 5 on top of mounting base 3 and mounting base 4, clamping the two ends of the steel strand. Once fully clamped, the operator activates the electric push rod 8 inside the countersunk hole. The output shaft of the electric push rod 8 moves mounting base 4, thus stretching the steel strand. During the stretching process, the pressure sensor 801 on mounting base 4 detects and transmits the thrust of the electric push rod 8. The operator can calculate the tensile strength of the steel strand by viewing the data transmitted by the pressure sensor 801. This convenient operation improves the testing effect. After the steel strand breaks and metal shavings fly out, the operator can activate the fan in the ventilation hole 100. The fan will draw the air above the collection chamber 200 through the collection hole 210 and the ventilation hole 100 to the outside of the base 1, thereby sucking the metal shavings on the shelf 2. The metal shavings will then fall through the collection hole 210 on the groove 201 into the collection frame 220 in the collection chamber 200. The filter holes on the collection frame 220 can isolate the metal shavings, preventing them from falling into the ventilation hole 100 below. After collection, the operator can slide the collection frame 220 out along the perforation to clean the metal shavings inside. This allows for convenient cleaning of the metal shavings on the shelf 2. Furthermore, the protective mechanism on the shelf 2 can block the top of the shelf 2 during inspection, further limiting the metal shavings and ensuring that they can fall into the collection frame 220 through the collection hole 210 on the groove 201. The operation is convenient.
[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application.
