Description

Technical Field

[0001] The utility model relates to the technical field of specimen manufacturing supplies, and particularly relates to a mold for inorganic binder stabilized materials. Background Art

[0002] Inorganic binder stabilized materials are a general term for a class of road construction materials in transportation engineering. Their characteristic is that they are mixed materials formed by mixing inorganic binders (such as cement) into the original aggregate. Inorganic binder stabilized materials are also called semi-rigid materials because their stiffness is between that of flexible pavement materials and rigid pavement materials. For inorganic binder stabilized materials, it is crucial to find a suitable mix ratio, and various indicators of the materials need to be detected. Among them, for the detection of indicators such as flexural tensile strength and flexural modulus, beam specimens of various inorganic mixture stabilized materials need to be made.

[0003] However, the existing molds are made of cast iron. The inner wall size of the small beam mold is 50mm×50mm×200mm, and the weight is 22.5kg; the inner wall size of the medium beam mold is 100mm×100mm×400mm, and the weight is 85kg; the inner wall size of the large beam mold is 150mm×150mm×550mm, and the weight is 150kg. For the beam specimens formed indoors, usually 2 to 4 people are required to carry the mold filled with the mixture to the loading platform, which is very labor-consuming and unsafe for manual handling.

[0004] Therefore, the existing technology needs to be improved. Summary of the Utility Model

[0005] The technical problem to be solved by the utility model is that manual handling of the mold is labor-consuming and unsafe. The purpose is to provide a mold for inorganic binder stabilized materials, which adopts corresponding technical means and has the beneficial effects of saving labor and reducing handling risks.

[0006] The utility model is realized through the following technical solutions:

[0007] A mold for inorganic binder stabilized materials, which includes a mold main body and a lifting platform.

[0008] The mold main body is provided with a chamber for accommodating pressurized materials, and a load plate that can be taken out and placed is arranged in the chamber.

[0009] The lifting platform includes a base, a lifting rod, and a platform arranged in sequence from bottom to top. The top end of the lifting rod is hinged to the platform. The base is provided with hydraulic cylinders that independently control the movement of the two sides of the lifting rod. A chute for restricting the mold main body is opened at the top of the platform.

[0010] In the above technical solution, first lower the lifting rod, and only need to manually place the mold body with the specimen module in the chute of the lifting platform. Then raise the lifting rod, and the lifting rod drives the platform and the mold body to rise until the edge of one side of the platform aligns with the edge of the loading platform. The mold body is lifted to the height of the loading platform by the lifting platform, which has the effect of saving physical strength and also avoids the dangerous situation of accidental injury caused by manual lifting. Then, the lifting rod on the side close to the loading platform remains stationary, and the lifting rod on the side far from the loading platform rises slightly, so that the platform forms a slope towards the loading platform. Finally, push the mold body by hand to make the mold body slide towards the loading platform. After the loading platform test is completed, the lifting rod on the side close to the loading platform still remains stationary, and the lifting rod on the side far from the loading platform drops slightly. Push the mold body by hand to make the mold body slide into the chute. Finally, the lifting platform descends and the staff removes the mold and replaces it.

[0011] Further, in the present utility model, a chute for restricting the mold body is provided at the top of the above platform. The width of the chute is the same as the width of the mold body, and the length of the chute extends to the edge of the platform.

[0012] Further, in the present utility model, a ramp plate is provided at the edge of the above platform.

[0013] Further, in the present utility model, the above mold body includes a bottom plate and a surrounding plate. A first connecting piece is provided on one side of the surrounding plate, and a second connecting piece is provided on the other side of the surrounding plate. The first connecting piece is provided with a first connecting hole, and the second connecting piece is provided with a second connecting hole aligned with the first connecting hole of the adjacent surrounding plate. A pin is inserted into the first connecting hole and the second connecting hole.

[0014] Further, in the present utility model, a plurality of the first connecting pieces and the second connecting pieces are provided on the surrounding plate.

[0015] Further, in the present utility model, a hinge seat is provided at the bottom of the above platform. A first hinge piece is provided on one side of the hinge seat, and the first hinge piece is provided with a round hole connected to the lifting rod. A second hinge piece is provided on the other side of the hinge seat, and the second hinge piece is provided with a long hole connected to the lifting rod.

[0016] Further, in the present utility model, there are multiple sets of the above mold bodies, and the widths of the multiple sets of mold bodies are the same, while the lengths and heights are different.

[0017] Further, in the present utility model, a demoulding coating is provided on the inner wall of the above chamber.

[0018] Further, in the present utility model, a button or a touch screen for controlling the lifting rod is provided on the above base.

[0019] Furthermore, in the present utility model, handles are provided on both sides of the above-mentioned test mold body.

[0020] Compared with the prior art, the present utility model has the following advantages and beneficial effects:

[0021] 1. Automatic lifting: The test piece module is installed inside the test mold body, and the test mold body is placed on the top of the lifting table. The lifting table lifts the test mold body to the height of the loading table. Using mechanical lifting instead of manual lifting can save labor, and at the same time, it can avoid accidental dropping and injury when handling the test piece module, with better safety.

[0022] 2. Convenient operation: After the lifting table lifts the test mold body to the height of the loading table, keep the lifting rod on the side close to the loading table stationary, and slightly raise the lifting rod on the side far from the loading table to make the platform form a slope towards the loading table. Finally, push the test mold body by hand to make it slide towards the loading table. After the test on the loading table is completed, keep the lifting rod on the side close to the loading table still, slightly lower the lifting rod on the side far from the loading table, and push the test mold body by hand to make it slide into the chute. It is more convenient to push the platform in or out, further saving physical strength. Description of the Drawings

[0031] Embodiment

[0032] This embodiment provides a test mold for inorganic binder stabilized materials, as Figures 1-4 shown, and the specific structure is as follows.

[0033] Please refer to Figure 1 shown. The test mold for inorganic binder stabilized materials in this embodiment mainly consists of two parts: a test mold body 1 and a lifting table 2. Among them, the test mold body 1 is used to accommodate the specimen module, and the lifting table 2 is used to drive the specimen module to rise.

[0034] Furthermore, the lifting table 2 includes three parts: a base 201, a lifting rod 202 and a platform 203. The base 201 is placed on the ground, the lifting rod 202 is installed on the top of the base 201, and the platform 203 is installed on the top of the lifting rod 202. A hydraulic cylinder is installed on the base 201, and the hydraulic cylinder is connected to the lifting rod 202 through a pipeline, and the lifting rod 202 is controlled by the hydraulic cylinder to move up or down.

[0035] In some embodiments of the present embodiment, in order to enable the platform 203 to form a "ramp" when needed, four lifting rods 202 are installed in this embodiment. The lifting rods 202 are hinged to the bottom of the platform 203. Two lifting rods 202 are located on the left side of the bottom of the platform 203, and two lifting rods 202 are located on the right side of the bottom of the platform 203. Combining Figure 1 and Figure 2 As shown, four hinge seats 3 are welded to the bottom of the platform 203. The right side of the platform 203 is used to dock with the loading table. Therefore, the first hinge pieces 301 are installed at the bottoms of the two hinge seats 3 on the right side, and the second hinge pieces 302 are installed at the bottoms of the two hinge seats 3 on the left side.

[0036] Furthermore, a round hole is provided in the first hinge piece 301. The shaft at the top of the lifting rod 202 passes through the round hole, and the lifting rod 202 can rotate around the round hole, realizing the hinged connection between the lifting rod 202 and the platform 203. Similarly, a horizontal long hole 303 is provided in the second hinge piece 302. The shaft at the top of the lifting rod 202 passes through the long hole 303, and the lifting rod 202 can rotate around the long hole 303 and can slide within the range of the long hole 303. When the platform 203 becomes a "ramp" with different heights on both sides, the shaft of the lifting rod 202 can slide within the long hole 303, making the hinge points on both sides match the distances between the lifting rods 202 on both sides, and the use effect is better.

[0037] In some embodiments of the present embodiment, combining Figure 1 As shown, a chute 204 is provided at the top of the platform 203. The test die body 1 is a cuboid box structure, and the width of the test die body 1 is the same as the width of the chute 204. Before lifting, the staff lifts the test die body 1 into the chute 204 at the top of the platform 203. The chute 204 plays a role in restricting the test die body 1 to prevent the test die body 1 from sliding back and forth during lifting.

[0038] Furthermore, the chute 204 extends to the right edge of the platform 203. When the edge of the platform 203 is aligned with the loading table, it is convenient to push the test die body 1 along the chute 204 onto the loading table. In order to facilitate lifting the test die body 1, a ramp plate 205 is installed at the right edge of the platform 203. The ramp plate 205 is wedge-shaped. When the lifting rod 202 drives the platform 203 to move to the lowest position, the side of the ramp plate 205 away from the platform 203 contacts the ground. The staff only needs to push the test die body 1 along the ramp plate 205 into the chute 204 of the platform 203, which is more convenient to use.

[0039] It should be noted that, combining Figure 1 As shown, handles 4 are fixedly connected to the outer walls on the left and right sides of the test die body 1. The handles 4 facilitate the staff to hold and apply force, either lift or push, to move the test die body 1.

[0040] In some embodiments of this embodiment, for the convenience of rapid mold removal, the test mold main body 1 is composed of a bottom plate 101 and four side plates 102, and the four side plates 102 are connected end to end. Combining Figure 1 , Figure 3 and Figure 4 As shown, on the left and right sides of the side plate 102, a first connecting piece 103 is installed on one side, and a second connecting piece 104 is installed on the other side. Both the first connecting piece 103 and the second connecting piece 104 are in a bent shape. The first connecting piece 103 and the second connecting piece 104 are respectively provided with vertically penetrating first connecting holes 1031 and second connecting holes 1041. When the edges of the two side plates 102 are brought close together and butted, the first connecting holes 1031 and the second connecting holes 1041 are vertically aligned, and the pin 106 is inserted into the first connecting holes 1031 and the second connecting holes 1041 to realize the fixed connection of the two side plates 102.

[0041] In this embodiment, three sets of test mold main bodies 1 of large, medium and small sizes can be set. The three sets of test mold main bodies 1 have the same width and different lengths and heights. So as to press different specimen modules, and the use effect is better.

[0042] It should be noted that in order to enhance the stability of the connection, multiple groups of first connecting pieces 103 and second connecting pieces 104 can be set at the connection of the two side plates 102, and the use effect is better.

[0043] In some embodiments of this embodiment, a bottom plate 101 and four side plates 102 enclose a chamber 105 for accommodating the pressurized material (specimen module). After the specimen module is installed, the loading plate 107 is placed. The loading plate 107 is made of hard aluminum alloy material and plays a role in preventing warping. The inner wall of the chamber 105 is coated with a demoulding coating, such as sodium alginate mixed with talcum powder, etc., which helps to remove the specimen module from the mold.

[0044] It should be noted that the base 201 is provided with buttons or a touch screen for controlling the lifting rod 202. By pressing the buttons or the touch screen, the lifting height of the test mold main body 1 can be controlled, and the use effect is better.

[0045] The working principle of the test mold for inorganic binder stabilized materials of the present utility model is as follows:

[0046] Clean all the components of the test mold body 1. First, place the bottom plate 101 on the ground, and then place the side plates 102 on top of the bottom plate 101 after applying release coating. Assemble the four side plates 102 of the test mold body 1, and insert the pin 106 for fixation after aligning the first connection hole 1031 and the second connection hole 1041. After the assembly of the test mold body 1 is completed, pour the weighed specified amount of stabilized material mixture into the chamber 105 in 2 to 3 times. After each pouring, gently and evenly tamp it with a rammer. Finally, place the loading plate 107 into the test mold body 1. After a period of time, start the lifting platform 2, make the edge of the ramp plate 205 of the lifting platform 2 fit the ground, push the test mold body 1 filled with the mixture into the chute 204, press the one-key elevation button, so that the test mold body 1 rises to the same height as the loading platform, and the platform 203 is also a ramp. Gently push the test mold body 1 and it will automatically slide to the loading platform.
