Description

Technical Field

[0001] This utility model relates to the field of wire rope clamping technology, specifically an expansion clamping device for wire rope tensile testing. Background Technology

[0002] The expansion clamping device for wire rope tensile testing is a device used to clamp one end of a wire rope with a controllable expansion force during tensile testing.

[0003] Based on the above, the inventors have discovered that: Currently, there are many wire rope tensile testing devices on the market, but in general wire rope tensile testing, the wire rope is manually clamped and installed by the operator. However, during the process of the wire rope being subjected to strong tension, the structure at the fixed end of the wire rope is very easy to become loose, and the operator is very likely to loosen the wire rope, thereby reducing the practicality of the device. Therefore, in view of this, the inventors have studied and improved the existing structure to provide an expansion clamping device for wire rope tensile testing, in order to achieve a more practical purpose. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: This utility model discloses an expansion clamping device for tensile testing of steel wire rope, comprising a plate body, a base plate fixed to the top of the plate body, a limiting mechanism at the top of the base plate, and an installation mechanism at the top of the plate body. The limiting mechanism includes: A limiting plate is provided at the top of the base plate. Two studs slide on the inner wall of the limiting plate, and the bottom ends of the two studs are fixed to the top of the base plate. Two threaded rings are provided at the top of the limiting plate, and the inner walls of the two threaded rings are threaded to the outer walls of the studs. A buffer pad is provided below the limiting plate, and the bottom end of the buffer pad is fixed to the top of the base plate.

[0005] As a preferred embodiment of this utility model, an electric push rod is fixed to the top of the plate, a connecting frame is fixed to the output end of the electric push rod, an elastic pad is fixed to one end of the connecting frame, and the elastic pad is disposed above the plate.

[0006] As a preferred embodiment of this utility model, the installation mechanism includes: The bottom block is fixed to the top of the plate, and the inner wall of the bottom block is provided with an elastic sleeve.

[0007] As a preferred embodiment of this utility model, the outer wall of the elastic sleeve is provided with a pressure plate, the outer wall of the pressure plate slides against one side of the bottom block, and the pressure plate is disposed at the top of the plate body.

[0008] As a preferred embodiment of this utility model, the inner wall of the pressure plate is fitted with two inserts, and one side of each insert is matched with the inner wall of the bottom block.

[0009] As a preferred embodiment of this utility model, the inner walls of both inserts are fitted with limiting posts, and the bottom ends of both limiting posts are matched with the inner walls of the plate.

[0010] As a preferred embodiment of this utility model, the inner wall of the elastic pad has a sliding column, and the bottom end of the sliding column is fixed to the top end of the plate.

[0011] The beneficial effects of this utility model are: 1. This solution uses a limiting plate that slides on the outer wall of the stud until the limiting plate and the buffer pad are combined to limit and clamp the outer wall of the wire rope. A threaded ring is used on the outer wall of the stud until the bottom end of the threaded ring abuts against the top end of the limiting plate. The electric push rod is controlled to drive the connecting frame to move up and down, thereby driving the elastic pad to clamp the outer wall of the wire rope with expansion force. This prevents the wire rope from loosening on the outside of the plate due to external tension, thus effectively improving the clamping stability of the device during the wire rope tensile test.

[0012] 2. In this solution, the outer wall of the elastic sleeve is engaged with the top of the base block. A pressure plate is slid on one side of the base block until the outer wall of the pressure plate abuts against the outer wall of the elastic sleeve. At the same time, the bottom end of the pressure plate is fastened to the top of the plate. The outer wall of the insert is fitted with the inner wall of the pressure plate, so that one side of the insert engages with the inner wall of the base block. The outer wall of the limiting post is slid with the inner wall of the insert, so that the bottom end of the limiting post matches the inner wall of the plate. This facilitates the elastic sleeve to guide and limit the outer wall of the wire rope, preventing the wire rope on the outside of the clamping device from shaking due to stretching when the device clamps the wire rope. Therefore, it is beneficial for the device to better clamp and install the wire rope. Attached Figure Description

[0015] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0016] Example: Figures 1-5 As shown, the present invention provides an expansion clamping device for tensile testing of steel wire rope, comprising a plate 1, a base plate 2 fixed to the top of the plate 1, a limiting mechanism 3 at the top of the base plate 2, and an installation mechanism 4 at the top of the plate 1. Limiting mechanism 3 includes: A limiting plate 31 is provided at the top of the base plate 2. Two studs 32 slide on the inner wall of the limiting plate 31. The bottom ends of the two studs 32 are fixed to the top of the base plate 2. Two threaded rings 33 are provided at the top of the limiting plate 31. The inner walls of the two threaded rings 33 are threaded to the outer walls of the studs 32. A buffer pad 34 is provided below the limiting plate 31. The bottom end of the buffer pad 34 is fixed to the top of the base plate 2.

[0017] As attached Figure 1 and Figure 5 As shown, an electric push rod 5 is fixed to the top of the plate 1, a connecting frame 6 is fixed to the output end of the electric push rod 5, an elastic pad 7 is fixed to one end of the connecting frame 6, the elastic pad 7 is set above the plate 1, a sliding column 8 slides on the inner wall of the elastic pad 7, and the bottom end of the sliding column 8 is fixed to the top of the plate 1, further improving the stability of the device in limiting the wire rope.

[0018] As attached Figure 1 , Figure 3 and Figure 4 As shown, the mounting mechanism 4 includes: The bottom block 41 is fixed to the top of the plate 1. The inner wall of the bottom block 41 is provided with an elastic sleeve 42, and the outer wall of the elastic sleeve 42 is provided with a pressure plate 43. The outer wall of the pressure plate 43 slides against one side of the bottom block 41. The pressure plate 43 is set at the top of the plate 1. The inner wall of the pressure plate 43 is fitted with two inserts 44. One side of each insert 44 matches the inner wall of the bottom block 41. The inner wall of each insert 44 is fitted with a limiting post 45. The bottom end of each limiting post 45 matches the inner wall of the plate 1. This facilitates the elastic sleeve 42 to guide and limit the outer wall of the wire rope, so as to prevent the wire rope on the outside of the clamping device from shaking due to stretching when the device clamps the wire rope. Therefore, it is beneficial for the device to better clamp and install the wire rope.

[0019] Working principle: In use, the outer wall of the elastic sleeve 42 is engaged with the top of the base block 41. The pressure plate 43 slides on one side of the base block 41 until its outer wall abuts against the outer wall of the elastic sleeve 42. At the same time, the bottom end of the pressure plate 43 is fastened to the top of the plate body 1. The outer wall of the insert post 44 is fitted onto the inner wall of the pressure plate 43, so that one side of the insert post 44 engages with the inner wall of the base block 41. The outer wall of the limiting post 45 slides against the inner wall of the insert post 44, so that the bottom end of the limiting post 45 matches the inner wall of the plate body 1. This facilitates the elastic sleeve 42 to guide and limit the outer wall of the wire rope, preventing the device from clamping the wire rope. The tensioning causes the wire rope on the outside of the clamping device to shake, which facilitates better clamping and installation of the wire rope. The limiting plate 31 slides on the outer wall of the stud 32 until the limiting plate 31 and the buffer pad 34 are combined to limit and clamp the outer wall of the wire rope. The threaded ring 33 is threaded on the outer wall of the stud 32 until the bottom end of the threaded ring 33 abuts against the top end of the limiting plate 31. The electric push rod 5 is controlled to drive the connecting frame 6 to move up and down, thereby driving the elastic pad 7 to clamp the outer wall of the wire rope with expansion force, avoiding the wire rope from loosening on the outside of the plate 1 due to external tension, and thus effectively improving the clamping stability of the device during the wire rope tension test.
