When the Rayleigh expansion tester is used, firstly, an expansion clamp is placed on the die holder 20, the width between the expansion clamps is measured, then under the condition that the expansion clamps are horizontally hung and stressed, the maximum width between the expansion clamps is measured, but in the use process, the die holder 20 of the conventional Rayleigh expansion tester is generally a cuboid with a concave middle, so that the detectable range is not large, an auxiliary device of the Rayleigh expansion tester is arranged, the die holders 20 with different shapes are arranged on the base 10, and the different die holders 20 are selected according to the shapes of the expansion clamps; or the base 10 may be provided with the die holder mounting hole 101, the bottom of the die holder 20 is provided with the mounting portion 201, when the die holder 20 is replaced, the mounting portion 201 is clamped in the die holder mounting hole 101, and the die holder 20 is replaced, which can be selected according to specific implementation environments, and the die holder 20 is flexibly detached due to the fact that the die holder 20 is movably connected to the base 10, so that the use and collection are more convenient.

In a preferred embodiment, the die holder 20 comprises a rectangular parallelepiped die holder.

Because of the large inclusion of the upper contact surface of the rectangular die holder 20, the width between expansion clamps of different shapes, such as hexagonal bottom, rectangular bottom, etc., can be detected; the application range of the Raschel clamp expansion tester is improved.

In another preferred embodiment, the base 10 is provided with the tray 102, and the tray 102 is disposed on one side of the base 10 and is used for accommodating the die holder 20.

In a specific use process, due to the fact that the shapes of the die holders 20 are different, the number of the die holders 20 is too large, in a placing process, it is obvious that the area of the base 10 is not enough to hold the die holders 20, therefore, the tray 102 is arranged on one side of the base 10, the tray 102 is detachably connected with the base 10, the tray 102 is mounted on the base 10 when in use, the tray 102 is not detached, and when the number of the die holders 20 is too large, the die holders 20 can be placed in the tray 102, so that the die holders 20 can be replaced conveniently.

Further, the auxiliary device of the Raschel clamp expansion tester comprises the upright post 30, the suspension arm 301 is arranged on the upright post 30, and the suspension post 301 is arranged on the suspension arm 301.

The distance between the expansion clamps under the condition of detecting expansion stress is required to be transversely hung on the upright post 30, and in order to be convenient for detecting the distance between the expansion clamps, the hanging arm 301 is arranged on the upright post, one end of the hanging arm is provided with a dial, the other end of the hanging arm is provided with a hanging post 3011, and the hanging post 3011 is used for hanging the expansion clamps so as to detect the distance between the expansion clamps under the stress state, and then the safety performance of the expansion clamps is calculated.

Further, the Raschel clamp dilatometer auxiliary device further comprises the hanging component 40, and the hanging component 40 is vertically connected to the hanging column 3011.

In order to facilitate the hanging of the expansion clip on the upright 30, the hanging component 40 is arranged, one end of the hanging component 40 is hung on the hanging post 3011 through a hook, the other end passes through the expansion clip, the contact position is adjusted to a proper position, and the expansion clip is horizontally hung on the upright 30, so that detection data can be conveniently obtained.

In a preferred embodiment, the suspension assembly 40 comprises the first boom 401 and the second boom 402, wherein one end of the first boom 401 is connected to the suspension post 3011, the other end is connected to one side of the expansion clamp, and the second boom 402 is connected to the other side of the expansion clamp.

The expansion clamp is hung on the first suspension arm 401, the suspension assembly 40 is rocked, in order to reduce the rocked force, the first suspension arm 401 and the second suspension arm 402 are arranged as suspension arms with non-adjustable length and no bending, nylon ropes are generally adopted as suspension ropes in normal use, deformation of the nylon ropes can occur in the use process, and therefore the first suspension arm 401 and the second suspension arm 402 can be replaced by hollow steel pipes which are not deformed, and the rocked force of the suspension assembly 40 can be reduced due to the action of air pressure.

Further, the second boom 402 includes the suspension ring 4021 and the hanger 4022, and the suspension ring 4021 and the hanger 4022 are disposed at both ends of the second boom 402, respectively.

Although the first suspension arm 401 and the second suspension arm 402 are made of hollow steel pipes to reduce the shaking force of the suspension assembly 40, when the original Rayleigh clamp expansion tester hangs a weight on the second suspension arm 402, a loop is formed on a nylon rope, one end of an expansion clamp is transferred into the loop, and in the operation process, the loop is troublesome, therefore, the suspension rings 4021 and the hooks 4022 are arranged at two ends of the second suspension arm 402, the hooks 4022 are hung on one side of the expansion clamp, the weight is hung on the suspension rings 4021, the operation process is simplified, and after the use is finished, the hooks 4022 can be hung on the first suspension arm 401, so that the collection is convenient.
