TECHNICAL FIELD
[0001] The utility model relates to a kind of Lea's clamp auxiliary fixing device for cement stability test, which is a device for assisting the fixation of Lea's clamp when boiling Lea's clamp in boiling box in cement stability test. BACKGROUND
[0002] Cement stability is one of the important indicators of cement quality, reflecting the uniformity of volume change during the setting and hardening process of cement. If cement contains excessive free lime, magnesium oxide or sulfur trioxide, uneven volume change will occur during setting and hardening, resulting in instability phenomena such as cracking, bending, brittleness and collapse. To ensure cement quality, cement stability test is therefore required.
[0003] There are two methods for cement stability test: Lea's clamp method and test cake method. In Lea's clamp method for cement stability test, Lea's clamp needs to be boiled in a boiling box, and the test piece is removed after boiling. In the prior art, when Lea's clamp is placed in the boiling box for boiling, Lea's clamp is placed on a placing rack in the boiling box. The placing rack has a double-layer fence structure. When Lea's clamp is placed in the placing rack, the test mold of Lea's clamp is located in the gap between the two fences of the lower layer, and the pointer of Lea's clamp rests on the fence of the upper layer. Since the gap between the fences is smaller than the diameter of the test mold of Lea's clamp, when placing Lea's clamp, the test mold of Lea's clamp needs to be placed in the gap of the upper layer first and then rotated by 90 degrees and placed in the gap of the lower layer. This operation is troublesome, and it is not convenient to take and place Lea's clamp. Moreover, Lea's clamp is not fixed after being placed on the placing rack, which is easy to shift, affecting the accuracy of test data. SUMMARY
[0004] In view of the above-mentioned defects in the prior art, the utility model provides a Lea's clamp auxiliary fixing device for cement stability test, which has a simple structure, is easy to operate, facilitates the taking and placing of Lea's clamp, and can reliably fix Lea's clamp.
[0005] The utility model is realized by the following technical solutions: a Lea's clamp auxiliary fixing device for cement stability test, characterized by: a rectangular parallelepiped fixing frame welded from stainless steel rods, a horizontal partition net with mesh holes is fixed in the fixing frame, the horizontal partition net divides the space in the fixing frame into upper and lower layers, a plurality of vertical gratings are fixed in the upper layer along the length direction of the fixing frame, the vertical gratings divide the upper layer into a plurality of Lea's clamp placing spaces, the middle part of the horizontal partition net in each Lea's clamp placing space is provided with an arc-shaped groove matching the outer diameter of the test mold of Lea's clamp, and a hand-held hanging ring is connected to the top of each end of the fixing frame; the horizontal partition net and the vertical grating are made of stainless steel.
[0006] When using the present invention, the Ray's clamp can be placed from above into the Ray's clamp placement space. The cylindrical test mold of the Ray's clamp is placed in the arc-shaped groove in the middle of the horizontal partition. The two pointers of the Ray's clamp can be pointed upward or leaned against the vertical grille on the side. The arc-shaped groove can limit and fix the Ray's clamp, effectively preventing the Ray's clamp from shifting. After the Ray's clamp is placed, the entire device is placed into the boiling box. The liquid in the boiling box can pass through the lower space of the fixed frame, the horizontal partition, and the vertical grille to cover the test mold, facilitating the boiling test. After boiling is completed, the entire device can be lifted out of the boiling box at any time using the hanging rings at both ends of the fixed frame.
[0007] Furthermore, two positioning rods are installed at the top of each Levitra clamp placement space. The two ends of the positioning rods are slidably connected to the edges of the fixed frame. The positioning rods are made of stainless steel. After the Levitra clamp is placed in the Levitra clamp placement space, the two positioning rods are slid toward the center. These two positioning rods secure the two pointers of the Levitra clamp, keeping them pointing upward, which helps ensure the accuracy of the test data.
[0008] The beneficial effects of the present invention are as follows: the present invention has a simple structure, and the Levitra clamp is easy to remove and place. The arc-shaped groove provided in the middle of the horizontal partition can reliably limit and fix the Levitra clamp, effectively preventing the Levitra clamp from shifting, reducing the difficulty of stability test operation, improving test efficiency and data accuracy, and can be lifted at any time after the Levitra method stability test is completed, which is simple to operate. The present invention is entirely manufactured from stainless steel, which has the advantages of high strength, strong durability, and good corrosion resistance. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] The present invention will be further described below by way of non-limiting embodiments and in conjunction with the accompanying drawings:
[0014] As attached Figure 1As shown, a Leclerc clamp auxiliary fixing device for cement stability testing includes a rectangular fixed frame 1 welded from stainless steel rods. A horizontally arranged mesh screen 2 with mesh holes is fixed in the fixed frame 1. The mesh screen 2 is also made of stainless steel and is welded to the fixed frame 1. The mesh screen 2 divides the space in the fixed frame 1 into two layers, upper and lower. In the upper layer, a plurality of vertical grids 3 are fixed at intervals along the length of the fixed frame 1. The vertical grids 3 divide the upper layer into a plurality of Leclerc clamp placement spaces 8. The vertical grids 3 are made of stainless steel and are welded to the fixed frame 1 and the mesh screen 2. The middle portion of the mesh screen in each of the Leclerc clamp placement spaces 8 is provided with an arc-shaped groove 5 that matches the outer diameter of the Leclerc clamp test mold. The arc-shaped groove 5 is used to place the Leclerc clamp test mold. Hand-held hanging rings 4 are connected to the top of each end of the fixed frame 1. The hand-carrying hanging ring 4 can be welded to the fixed frame 1 , and the hand-carrying hanging ring 4 can also be connected to the fixed frame 1 in a rotatable manner.
[0015] In the present invention, the size of the fixing frame 1 is determined according to the size of the boiling box.
[0016] During use, the Levitra clip can be placed from the top of the fixed frame into the Levitra clip placement space 8. The cylindrical Levitra clip test mold is placed in the arcuate groove 5 in the middle of the horizontal screen 2. The arcuate groove 5 limits and secures the Levitra clip. The two pointers of the Levitra clip can be pointed upward or against the vertical grid 3 on the side. Multiple Levitra clips can be placed at once depending on the test requirements. After the Levitra clips are placed, the entire device can be placed into the boiling box using the carrying loop 4. After boiling is completed, the entire device can be removed from the boiling box at any time using the carrying loop 4.
[0017] As attached Figure 2-Figure 3 The figure shows another preferred structure of the present invention. In this embodiment, two positioning rods 6 are provided at the top of each of the Lei's clamp placement spaces 8. The two ends of the positioning rods 6 are respectively connected to the frame edges of the fixed frame 1 in a sliding manner. The two ends of the two positioning rods 6 are respectively connected to the frame edges of the fixed frame 1 through slip rings 7. The slip rings 7 can slide along the frame edges of the fixed frame 1. At the same time, there is a certain friction resistance between the slip rings 7 and the frame edges of the fixed frame 1. The friction resistance is preferably such that the positioning rods 6 need to be manually moved to prevent the positioning rods 6 from sliding automatically. The positioning rods 6 are also made of stainless steel. After the Lei's clamp is placed in the Lei's clamp placement space 8, the two positioning rods 6 are slid toward the middle. The two pointers of the Lei's clamp can be fixed by the two positioning rods 6 so that the pointers of the Lei's clamp remain facing upwards, which is conducive to ensuring the accuracy of the test data.
[0018] The utility model has a simple structure, and the Reye's clamp is easy to take out and put away, and the Reye's clamp can be reliably fixed when boiling. The utility model can effectively reduce the difficulty of the Reye's method test operation of the stability test, and improve the test efficiency and data accuracy.
[0019] The other parts of this embodiment are all prior art and are not described here again.
