Technical Field

[0001] The utility model relates to the technical field of reinforced concrete drainage pipe forming devices, in particular to a reinforced concrete drainage pipe forming device. Background Art

[0002] Prefabricated reinforced concrete pipes are made of concrete and steel bars using corresponding casting molds. Compared with steel pipes, concrete pipes can save a lot of steel and extend their service life. They require less investment in plant construction and are easy to lay and install. They can be used as water pipes in urban construction foundations, can drain sewage, prevent floods, and are used as water pipes and farmland wells in some special factories and mines.

[0003] However, when making reinforced concrete drainage pipes through a core mold vibration pipe making machine, the operator needs to manually fix the inner mold and the chassis of the pipe making machine together. Since both the inner mold and the chassis are arranged in a columnar structure, it is cumbersome to align the fixed components on the inner mold with the chassis, which results in low efficiency in fixing the inner mold and the chassis, which is not conducive to the rapid assembly of the mold.

[0004] Therefore, a drain pipe device that is easier to operate is needed. Utility Model Content

[0005] In order to solve the above problems, the utility model provides a reinforced concrete drainage pipe forming device, which can make the fixed clamping ring on the inner mold engage into the fixed ring through the lifting equipment, thereby facilitating the fixing of the clamping ring on the chassis, so that the clamping ring can be quickly positioned.

DETAILED DESCRIPTION

[0028] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments. Example 1

[0029] In order to make the mold more convenient to assemble, a reinforced concrete drainage pipe forming device is designed. The specific plan is as follows:

[0030] like Figure 1-7 As shown, a reinforced concrete drainage pipe forming device includes an inner mold 3, and a lifting mechanism 2 and a positioning mechanism 4 are respectively fixed at both ends of the inner mold 3. The positioning mechanism 4 includes a clamping ring 401 and a fixing ring 403. The clamping ring 401 is fixedly installed at the end of the inner mold 3, and the fixing ring 403 is clamped and installed on the clamping ring 401. The fixing ring 403 is fixedly connected to a chassis 402. The fixing ring 403 is annularly provided with a plurality of clamping grooves 404 at equal intervals. The chassis 402 is fixedly connected with a bottom plate 405, and the inner mold 3 is clamped and installed with a main mechanism 1.

[0031] Specifically, the diameter of the chassis 402 is larger than the diameter of the fixing ring 403, and the diameter of the clamping ring 401 is smaller than the diameter of the fixing ring 403. When the clamping ring 401 is engaged with the inside of the fixing ring 403, it can be installed on the top of the chassis 402 by fixing bolts.

[0032] Specifically, a plurality of slots 404 are equidistantly arranged in a ring shape, and a clamping ring 401 is mounted on the slot 404 . When the protruding portion of the clamping ring 401 is engaged with the slot 404 , the clamping ring 401 can be quickly engaged with the fixing ring 403 .

[0033] Specifically, the interior of the inner mold 3 is connected to the chassis 402, the inner diameter of the bottom plate 405 is smaller than the inner diameter of the chassis 402, and the bottom plate 405 supports the steel cage, so that concrete slurry can be poured on the steel cage.

[0034] Specifically, the lifting mechanism 2 includes a positioning ring 201 and a fixed block 202. The positioning ring 201 is fixedly installed on the top of the inner mold 3. The fixing block 202 and the cover plate 203 are fixedly connected to the positioning ring 201. When the hook of the crane is connected to the fixed block 202, the crane can easily lift the positioning ring 201.

[0035] Specifically, the inner diameter of the positioning ring 201 is equal to the inner diameter of the inner mold 3, and a plurality of fixing blocks 202 are arranged equidistantly in a ring. When the crane drives the fixing blocks 202 to move, the positioning ring 201 can drive the inner mold 3 to move.

[0036] Specifically, the cover plate 203 is arranged in an octagonal structure, and the width of the cover plate 203 is greater than the diameter of the positioning ring 201. When the cover plate 203 contacts the top plate 103, the outer mold 101 and the inner mold 3 can be engaged together.

[0037] Specifically, the main body structure 1 includes an outer mold 101 and a top plate 103. The outer mold 101 is clamped and installed on the inner mold 3. The top plate 103 and a vibrating core rod 102 are fixedly connected to the outer mold 101. When pouring concrete slurry, the vibrating core rod 102 can make the concrete slurry pouring more uniform.

[0038] Specifically, the diameter of the outer mold 101 is larger than the diameter of the inner mold 3 , and the vibration core rod 102 is located at the center of the inner mold 3 . When the drainage pipe is solidified, the inner mold 3 is lifted by a crane to separate the water pipe from the vibration core rod 102 .

[0039] Specifically, the cover plate 203 abuts against the top plate 103 , and the width of the cover plate 203 is greater than that of the top plate 103 . The top plate 103 is arranged in a hexagonal structure. When the cover plate 203 abuts against the top plate 103 , the outer mold 101 can be in a sealed state.

[0040] Instructions for use:

[0041] First, the operator can place the steel cage in the chassis 402 by means of a crane. Since the chassis 402 is fixedly connected with a bottom plate 405, when the water-stop steel rings welded at both ends of the steel cage collide with the bottom plate 405, the steel cage can be located inside the chassis 402. Then, the crane is connected to the fixing block 202 installed on the positioning ring 201. When the crane is started, the positioning ring 201 can drive the cover plate 203 and the inner mold 3 to move, thereby moving the inner mold 3 toward the chassis 402. When the end of the inner mold 3 is sleeved on the chassis 402, the steel cage can be located inside the inner mold 3.

[0042] When the inner mold 3 needs to be fixed, the clamping ring 401 fixed at the bottom of the inner mold 3 can be engaged and installed into the fixing ring 403 according to the clamping groove 404 provided on the fixing ring 403, so that the clamping ring 401 is located at the top of the chassis 402, and then the fixing bolts are installed in the clamping ring 401 and the chassis 402 using tools. When the clamping ring 401 conflicts with the chassis 402, it can be fixed at the top of the chassis 402, so as to facilitate the rapid positioning of the clamping ring 401;

[0043] After the clamping ring 401 is fixed, the inner mold 3 can be in contact with the chassis 402, and the crane can lift the positioning ring 201 to move the inner mold 3 into the outer mold 101. When the top plate 103 fixed on the top of the outer mold 101 is in contact with the bottom end of the cover plate 203, the cover plate 203 can seal the outer mold 101; and a vibrating core rod 102 is installed on the outer mold 101. When the outer mold 101 and the inner mold 3 are engaged together, the vibrating core rod 102 can be located at the center of the inner mold 3, and concrete slurry is poured into the steel cage. Starting the vibrating core rod 102 can make the concrete slurry poured more evenly, thereby improving the casting effect of the drainage pipe; when the pipeline is cast, the inner mold 3 is lifted out of the outer mold 101, and the fixing bolts installed on the clamping ring 401 are removed, so that the inner mold 3 can be separated from the cast pipeline, thereby facilitating the maintenance of the drainage pipe.
