Description

Technical Field

[0001] This utility model belongs to the technical field of concrete precast block molds, and particularly relates to a mold for a transformer foundation concrete precast component. Background Technology

[0002] Concrete precast block molds are specialized molding tools used for the mass production of precast concrete components. They are essentially containers of a specific shape into which mixed concrete is poured. After drying, curing, and molding, the concrete is demolded to obtain precast concrete components with uniform shape and size.

[0003] Because concrete precast components are relatively large and heavy, conventional concrete precast block molds typically remove the panels around the cavity (container) during demolding to expose the perimeter of the concrete precast component, making it easier for handling equipment to remove it from the mold. Therefore, if the next concrete precast component needs to be manufactured, the disassembled panels need to be reassembled into the original cavity, resulting in low production efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide a mold for precast concrete components for transformer foundations to solve the technical problems described in the background.

[0005] The aforementioned transformer foundation concrete precast component mold includes:

[0006] The base is equipped with guide columns and support columns;

[0007] The lifting seat is equipped with a bushing that slides on the guide column. The lifting seat is provided with a cavity for injecting concrete. The bottom wall of the cavity is provided with a base plate that can be raised and lowered inside. The support column passes through the bottom wall of the cavity and is connected to the base plate to support the base plate to a constant height.

[0008] The hydraulic lifting drive module is connected to the lifting seat so that the concrete is cured and formed in the cavity into a preform. After the preform is formed, the hydraulic lifting drive module drives the lifting seat to descend. At this time, the height of the base plate remains constant, thereby removing the preform from the cavity.

[0009] According to the described technical solution, the present invention achieves the following beneficial effects:

[0010] 1. After the concrete injected into the cavity dries and solidifies into a preform, the hydraulic lifting drive module drives the lifting seat to descend. The cavity also descends with the lifting seat. Since the support column passes through the bottom wall of the cavity to support the bottom plate, the descent of the cavity will not cause the bottom plate to descend. At this time, the bottom plate supporting the preform is not moved by the cavity, so as to separate the preform from the cavity. At the same time, the periphery of the preform is exposed. Therefore, demolding can be completed without disassembling the components surrounding the preform around the cavity. This allows the handling equipment to conveniently handle the preform by clamping both sides of the preform, thereby improving production efficiency.

[0011] 2. When the precast component is removed from the base plate and the next precast component needs to be manufactured, the hydraulic lifting drive module drives the lifting seat to rise and reset. The cavity also resets as the lifting seat rises. Since the support column passes through the bottom wall of the cavity to support the base plate, the rise of the cavity will not drive the base plate to rise, so that the base plate is placed at the bottom of the cavity. At this time, another concrete can be injected into the cavity for curing and molding into another precast component.

[0012] To further optimize the above technical solutions, they can be combined with one or more of the following implementation methods without conflict.

[0013] In some embodiments, a perimeter partition for isolating concrete is placed on the perimeter wall of the cavity, and a bottom partition for isolating concrete is placed on the upper wall of the bottom plate, with the bottom partition supporting the bottom partition.

[0014] Alternatively, in some embodiments, a thin film sleeve for isolating concrete is placed inside the cavity, and the bottom plate supports the thin film sleeve;

[0015] Based on the aforementioned technical solution, the following beneficial effects can be further achieved:

[0016] 1. During the separation process between the precast component and the cavity, it can prevent the precast component from sticking to the cavity and causing damage to the precast component, and reduce the pressure when the hydraulic lifting drive module drives the lifting seat to descend;

[0017] 2. When the handling equipment removes the precast components from the base plate, it can prevent the precast components from sticking to the base plate, thus avoiding increasing the difficulty of handling.

[0018] In some embodiments, the lifting base is provided with a column hole, the support column passes through the column hole, there is a gap between the support column and the column hole, and the base is installed on the vibration module connected to the support column;

[0019] Based on the aforementioned technical solution, during the process of injecting concrete into the cavity, the vibration module can drive the support column to vibrate the concrete on the base plate, thereby eliminating air bubbles and air in the concrete and improving the density of the concrete.

[0020] In some implementations, heating elements for heating the concrete are mounted on the outer periphery of the cavity;

[0021] Based on the aforementioned technical solution, during the drying and curing process of concrete in the mold cavity, the concrete can be heated by a heating element, thereby improving the curing efficiency of the concrete.

[0022] In some implementations, the lifting platform is equipped with height-limiting posts for contacting the base plate;

[0023] Based on the aforementioned technical solution, during the lifting process, the height of the lifting seat is limited and positioned by a height-limiting column, so that after the hydraulic lifting drive module drives the lifting seat to rise and reset, the base plate can accurately stop at a specific position in the cavity, thereby ensuring that the dimensions of each molded preform are consistent.

[0024] In some embodiments, a detachable molding block is mounted on the base plate; based on the above technical solution, the cavity can be solidified to form a precast component with a hollowed-out lower structure.

[0025] In some embodiments, the guide pillars are located outside the four corners of the cavity, and a conveying mechanism for clamping the preform is provided above the cavity;

[0026] Based on the aforementioned technical solution, the guide column can avoid the handling equipment during the process of handling the precast component by clamping it on both sides.

[0027] In some implementations, the base is submerged and fixed underground, and the height of the base plate is the same as or higher than the ground level.

[0028] Based on the aforementioned technical solution, handling equipment or operators can easily remove prefabricated components from the base plate. Attached Figure Description

[0037] To make the objectives, technical solutions, and advantages of this utility model clearer, the following description is provided with reference to the accompanying drawings. Example 1

[0038] like Figures 1 to 4 As shown, this embodiment provides a transformer foundation concrete precast component mold, which includes a base 1, a lifting seat 2, and a hydraulic lifting drive module 5.

[0039] The base 1 is submerged and fixed underground, and guide columns 11 and support columns 12 are installed on the base 1. The vibration module is installed on the base 1 and connected to the support columns 12.

[0040] The lifting seat 2 is equipped with a bushing 21 that slides on the guide post 11, and the lifting seat 2 is provided with a through hole 22.

[0041] The lifting platform 2 is equipped with a cavity 3 for injecting concrete, and a perimeter plate 31 for isolating the concrete is placed on the periphery of the cavity 3. Heating tubes 32 for heating the concrete are installed on the outer periphery of the cavity 3. A height limiting column 23 is installed on the lifting platform 2. A handling mechanism for clamping and picking up precast components is provided above the cavity 3.

[0042] The bottom wall of the cavity 3 is provided with a base plate 4 that can be raised and lowered internally. Support columns 12 pass through through-holes 22 to connect the support columns 12 to the base plate 4 through the bottom wall of the cavity 3. A gap exists between the support columns 12 and the through-holes 22 to support the base plate 4 at a constant height. The height of the base plate 4 is the same as or higher than the ground level. A bottom partition plate 41, which isolates the concrete, is placed on the upper wall of the base plate 4. Height-limiting columns 23 are used to contact the base plate 4. Guide columns 11 are located outside the four corners of the cavity 3.

[0043] The hydraulic lifting drive module 5 is connected to the lifting seat 2 so that the concrete is solidified and formed into the precast part in the cavity 3. Then, the hydraulic lifting drive module 5 drives the lifting seat 2 to descend. At this time, the height of the base plate 4 remains constant, thereby removing the precast part from the cavity 3.

[0044] The following is an instruction manual for using a precast concrete mold for a transformer foundation, as described in this embodiment.

[0045] Concrete is poured into cavity 3. Heating element 32 heats the concrete until it dries and solidifies within cavity 3, forming a precast component. Subsequently, hydraulic lifting drive module 5 drives lifting seat 2 to descend, and cavity 3 descends along with it. Since support column 12 passes through the bottom wall of cavity 3 and supports base plate 4, the descent of cavity 3 does not cause base plate 4 to descend. At this point, base plate 4, carrying the precast component, is also not moved by cavity 3, thus separating the precast component from cavity 3. Afterward, transport mechanism removes the precast component from base plate 4. After the precast component is removed, peripheral partition 31 and bottom partition 41 are torn off the precast component.

[0046] When manufacturing the next preform, the hydraulic lifting drive module 5 drives the lifting seat 2 to rise and reset. The cavity 3 also resets as the lifting seat 2 rises. Since the support column 12 supports the base plate 4 through the bottom wall of the cavity 3, the rise of the cavity 3 will not cause the base plate 4 to rise, so that the base plate 4 returns to the lower part of the cavity 3. At this time, the height limiting column 23 contacts the bottom wall of the base plate 4 to position the lifting seat 2. After that, the bottom partition plate 41 can be placed back on the base plate 4, and the peripheral partition plate 31 is placed back against the inner peripheral wall of the cavity 3. After that, another concrete can be injected into the cavity 3 for curing and molding into another preform. Example 2

[0047] like Figure 1 , 2 As shown in Figure 5, this embodiment provides a transformer foundation concrete precast component mold, which includes a base 1, a lifting seat 2, and a hydraulic lifting drive module 5.

[0048] The base 1 is submerged and fixed underground, and guide columns 11 and support columns 12 are installed on the base 1. The vibration module is installed on the base 1 and connected to the support columns 12.

[0049] The lifting seat 2 is equipped with a bushing 21 that slides on the guide post 11, and the lifting seat 2 is provided with a through hole 22.

[0050] The lifting platform 2 is equipped with a cavity 3 for injecting concrete. Heating tubes 32 for heating the concrete are installed around the outer periphery of the cavity 3. A height-limiting column 23 is installed on the lifting platform 2. A handling mechanism for clamping and picking up precast components is provided above the cavity 3.

[0051] The bottom wall of the cavity 3 is equipped with a base plate 4 that can be raised and lowered internally. Support columns 12 pass through through-holes 22 to connect with the base plate 4 through the bottom wall of the cavity 3. A gap exists between the support columns 12 and the through-holes 22 to support the base plate 4 at a constant height. The height of the base plate 4 is the same as or higher than the ground level. Height-limiting columns 23 are used to contact the base plate 4. Guide columns 11 are located at the four corners of the cavity 3. Removable molding blocks 33 are installed on the base plate 4. A membrane sleeve for isolating concrete is placed inside the cavity 3, and the base plate 4 supports the membrane sleeve.

[0052] The hydraulic lifting drive module 5 is connected to the lifting seat 2 so that the concrete is solidified and formed into the precast part in the cavity 3. Then, the hydraulic lifting drive module 5 drives the lifting seat 2 to descend. At this time, the height of the base plate 4 remains constant, thereby removing the precast part from the cavity 3.

[0053] The following is an instruction manual for using a precast concrete mold for a transformer foundation, as described in this embodiment.

[0054] Concrete is poured into cavity 3. Heating element 32 heats the concrete until it dries and solidifies within cavity 3, forming a precast component. Subsequently, hydraulic lifting drive module 5 drives lifting seat 2 downwards, causing cavity 3 to descend as well. Since support column 12 passes through the bottom wall of cavity 3 and supports base plate 4, the descent of cavity 3 does not cause base plate 4 to descend. At this point, base plate 4, carrying the precast component, is also not affected by cavity 3, thus separating the precast component from cavity 3. Afterwards, the transport mechanism removes the precast component from base plate 4. Once the precast component is removed, the film sleeve can be peeled off.

[0055] If it is necessary to manufacture the next preform, the hydraulic lifting drive module 5 drives the lifting seat 2 to rise and reset. The cavity 3 also resets as the lifting seat 2 rises. Since the support column 12 passes through the bottom wall of the cavity 3 to support the base plate 4, the rise of the cavity 3 will not drive the base plate 4 to rise, so that the base plate 4 is placed back in the lower part of the cavity 3. At this time, the height limiting column 23 contacts the bottom wall of the base plate 4 to position the lifting seat 2. After that, another film sleeve can be placed in the cavity 3. After that, another concrete can be injected into the cavity 3 for curing and molding into another preform.
