Description

Technical Field

[0001] This utility model belongs to the field of steel wire head strength testing technology, and particularly relates to a steel wire head strength testing device. Background Technology

[0002] A wire rod end strength testing device generally consists of a loading mechanism, a clamping system, a measuring system, and a support structure.

[0003] A gradually increasing axial tensile force is applied to the wire rope abutment head through a loading mechanism. Force sensors measure the tensile force value in real time, while displacement sensors simultaneously monitor the deformation of the abutment head. When the tensile force reaches the ultimate strength of the abutment head, it will fail, such as fracture or slippage. The test apparatus evaluates the strength and mechanical properties of the wire rope abutment head by measuring and recording the tensile force value at failure and the corresponding deformation.

[0004] In this process, the clamps used to hold and fix the wire abutment in the clamping system are the key tools to maintain stability during the wire measurement. The clamps in the existing technology are not convenient for holding and fixing wire abutments of different sizes, and the installation process of the wire abutment and the clamp is relatively cumbersome, which greatly affects the work efficiency of the test experiment.

[0007] The clamp body has an opening on its exterior and semi-circular locking grooves with gradually increasing radii are formed from bottom to top inside the clamp body. The locking grooves are used to place the steel wire anchors and are connected to the opening. The bottom of the clamp body has a movable groove that is connected to the opening and the locking grooves and is used to place the steel wire.

[0008] Preferably, the fixture body is provided with semi-circular slide rails symmetrically arranged on the upper and lower sides, and the inner wall of the outer protective shell is provided with a slide groove corresponding to the slide rail, and the slide rail is slidably connected inside the slide groove.

[0009] Preferably, the slide rail is fixedly connected to the fixture body.

[0010] Preferably, the outer protective shell has symmetrically formed limiting grooves on its exterior, and the limiting grooves are movably connected to limiting plates.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-5 This utility model provides a technical solution:

[0024] A steel wire head strength testing device includes a clamp body 3 assembled with a tensile testing machine, and a fixing block 2 fixed to the top of the clamp body 3 and fixed to the tensile testing machine. The clamp body 3 is designed as a columnar structure, and an outer protective shell 1 is movably connected to the outside of the clamp body 3.

[0025] The clamp body 3 has an opening on its exterior, and the clamp body 3 has semi-circular locking grooves 12 with gradually increasing radii from bottom to top inside. The locking grooves 12 are used to place the steel wire end caps. The locking grooves 12 are connected to the opening. The bottom of the clamp body 3 has a movable groove 6 that is connected to the opening and the locking grooves 12. The movable groove 6 is used to place the steel wire.

[0026] The clamp body 3 is symmetrically provided with semi-circular slide rails 5 on its upper and lower sides. The inner wall of the outer protective shell 1 is provided with a slide groove 13 corresponding to the slide rail 5. The slide rail 5 is slidably connected inside the slide groove 13 and is fixedly connected to the clamp body 3.

[0027] Specifically, the outer protective shell 1 has symmetrically formed limiting grooves 7 on its exterior, and the limiting grooves 7 are movably connected to the limiting plate 8. The fixture body 3 has a T-shaped storage cavity 9 inside, and a connecting plate 11 is movably connected inside the storage cavity 9. The connecting plate 11 is perpendicularly fixed to the limiting plate 8, and the size of the storage cavity 9 matches the limiting plate 8 and the connecting plate 11. A spring 10 is fixed between the connecting plate 11 and the storage cavity 9. The end of the limiting plate 8 away from the connecting plate 11 is chamfered.

[0028] Working principle:

[0029] During operation, the user first rotates the outer protective shell 1, which slides and connects to the slider via the slide rail 5. This allows the outer protective shell 1 to rotate stably outside the fixture body 3, exposing the opening on the outside of the fixture body 3 and revealing the different sized engaging slots 12 inside the fixture body 3. The user then places the corresponding wire abutment into the corresponding engaging slot 12, and the wire at the bottom of the wire abutment moves into the movable slot 6. At this point, the wire abutment is initially fixed to the fixture body 3. Then, the user rotates the outer protective shell 1 again to cover the opening on the surface of the fixture body 3. The outer body 3 is driven by the spring 10 to elastically compress the connecting plate 11 and drive the limiting plate 8 to move. When the limiting plate 8 corresponds to the limiting groove 7 on the outside of the outer protective shell 1, the limiting plate 8 extends into the limiting groove 7 to limit and fix the outer protective shell 1, and combines the outer protective shell 1 with the clamp body 3. Subsequently, the user presses the limiting plate 8 in the limiting groove 7 with his finger to move the limiting plate 8 and the connecting plate 11 completely into the storage cavity 9. At this time, the outer protective shell 1 is unrestricted, and the user can rotate the outer protective shell 1 at will, including the external opening of the clamp body 3, and the user can remove the wire abutment.

[0030] The device of this application connects and fixes the fixture body 3 to the tensile testing machine through the fixing block 2. The loading device in the tensile testing machine drives the fixture body 3 to move, pulling and stretching the steel wire head. The sensor in the tensile testing machine monitors and transmits data.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
