Description

Technical Field

[0001] This application relates to the technical field of building installation, and in particular to a silo electric slip form device. Background Art

[0002] The silo electric slip form (referred to as electric slip form for short) is an extension and development of the hydraulic slip form. It has developed from the traditional hydraulic cylinder lifting and small steel formwork assembled piece by piece to electric screw lifting and large-scale adjustable forming formwork. It is a complete set of standardized construction equipment with simple operation and high automation, and is particularly suitable for building construction such as deep valley piers over 100 meters, towering TV towers and chimneys, and super-large diameter group silos and core tubes.

[0003] In the related art, generally, a lifting device is used to lift the slip form device. The slip form device consists of two coaxially arranged slip forms, and there is a pouring gap formed between the two slip forms. During construction, first, the two slip forms are brought into contact with the foundation, and concrete is poured into the pouring gap. After the concrete in the pouring gap has completely solidified, the slip form device is lifted by the lifting device, and concrete is continuously poured on the solidified concrete. The above steps are repeated to complete the construction of the silo.

[0004] In view of the above related art, during the process of lifting the slip form device by the lifting device, the lifting device bears the weight of the entire slip form device, which has certain requirements for the bearing capacity and strength of the lifting device. During the lifting process, the lifting device may be overloaded, resulting in damage to the lifting device and further affecting the construction efficiency. Therefore, there is an urgent need for a device that can support the slip form device during the lifting process and improve the stability of the slip form device. Summary of the Invention

The guide rods are parallel to the axial direction of the second mounting ring. One end of the guide rod is fixedly connected to the foundation, and the first mounting ring slides along the length direction of the guide rod. A plurality of support frames are fixedly connected to the bottom wall of the first mounting ring, and the plurality of support frames are circumferentially spaced apart along the first mounting ring; The inner side wall of the first mounting ring is fixedly connected to the first sliding form, and the outer side wall of the second mounting ring is fixedly connected with a second sliding form, and a pouring gap is formed between the first sliding form and the second sliding form; The first support assembly includes a first support rod and a first counterweight. One end of the support frame away from the first mounting ring is connected with a first support rod along the axis direction of the support frame.

One side of the first support rod away from the first mounting ring is detachably connected with a first counterweight; It further includes a lifting device, and the lifting device is used to drive the first mounting ring to slide along the length direction of the guide rod.

[0007] By adopting the above technical solution, during construction, concrete is poured into the filling gap. After the concrete solidifies, the first mounting ring and the second mounting ring are lifted by the lifting device. During the lifting process, in order to reduce the load on the lifting device, by setting the first support assembly, when the first mounting ring is lifted, one end of the first support rod is fixedly connected to the first counterweight, so that the first support rod supports the first mounting ring to ensure the stability of the first mounting ring during the lifting process.

[0019] By adopting the above technical solution, in order to drive a support rod to rotate along the circumferential direction of the second mounting ring, by setting a first driving component, since the first support rod and the first counterweight are detachably connected, the first support rod and the first counterweight are disassembled, and the first motor drives the second rotating shaft to rotate, further driving the pulling rope to rotate the first support rod to the second position.

A first counterweight 32 is detachably connected to the side of the first support rod 31 away from the first mounting ring 1.

[0035] Referring to Figure 3 and Figure 4 , specifically, a first chute 2221 for accommodating the first support rod 31 is formed in the bottom wall of the first vertical rod 222 along the axial direction of the second mounting ring. One end of the first support rod 31 is located in the first chute 2221 and slides in the first chute 2221. The first support rod 31 is fixedly connected to the support frame 22 by screws. When the first mounting ring 1 and the second mounting ring 2 are lifted by a lifting device, the first support rod 31 supports the support frame 22, and further supports the first mounting ring 1 and the second mounting ring 2.

[0039] Refer to Figure 4 and Figure 5 , to enable the first support rod 31 to rotate along the support frame 22, a second chute 2223 is formed through the end of the support frame close to the first support rod 31 in the radial direction of the first installation ring 1. The second chute 2223 communicates with the first chute 2221. The second chute 2223 is used to provide space for the first support rod 31 to rotate. Specifically, a first rotating shaft 2224 is provided between the limiting block 311 and the first support rod 31. The first rotating shaft 2224 is arranged parallel to the circumferential direction of the first installation ring 1. The first rotating shaft 2224 is rotatably connected between the two limiting blocks 311. The first support rod 31 is fixedly sleeved on the first rotating shaft 2224. When the limiting block 311 slides along the axis direction of the first installation ring 1 to contact the limiting groove 2222, the first support rod 31 can rotate from the first position to the second position for personnel to operate.

[0040] Refer to Figure 5, in order to drive the rotation of the first support rod 31 in the circumferential direction of the first mounting ring 1, the silo electric slip form device further includes a first driving assembly 5. The first driving assembly 5 includes a second rotating shaft 51, a first cable 52 and a first motor 53. The first rotating shaft 2224 is rotatably connected to the side of the first mounting ring 1 away from the second slip form 21.

The housing of the first motor 53 is fixedly connected to the first mounting seat 321, and the output shaft of the first motor 53 is coaxially and fixedly connected to the second rotating shaft 51.

[0041] Referring to Figure 5 , since the connection between the first support rod 31 and the first counterweight 32 is detachable, when personnel need to work at high altitude, the first support rod 31 and the first counterweight 32 can be detached. The first motor 53 drives the second rotating shaft 51 to rotate, further driving the first support rod 31 to rotate.

[0042] Referring to Figure 7 , when the second mounting ring 2 is lifted, in order to further improve the supporting force for the second mounting ring 2, the silo electric slip form device further includes a second supporting assembly 6. The second supporting assembly 6 is installed at the bottom of the second mounting ring 2. The second supporting assembly 6 includes a second support rod 61 and a second counterweight 62. The second support rod 61 is parallel to the axis direction of the second mounting ring 2. The second support rod 61 is of a telescopic rod structure. The fixed section 611 of the second support rod 61 is fixedly connected to the second mounting ring 2, and the movable section 612 of the second support rod 61 is fixedly connected to the second counterweight 62. One end of the movable section 612 close to the fixed section 611 is slidably connected, and the fixed section 611 and the movable section 612 are fixedly connected by screws.

[0043] The implementation principle of a silo electric slip form device according to an embodiment of the present application is as follows: during operation, the first slip form 12 and the second slip form 21 first abut against the ground. The second mounting ring 2 is lifted by a lifting device, and concrete is poured into the pouring gap 13. After the concrete solidifies, the lifting device drives the first mounting ring 1 and the second mounting ring 2 to slide along the length direction of the guide rod 11, and concrete is continuously poured. When the first mounting ring 1 slides along the length direction of the guide rod 11, the first mounting ring 1 can be supported by the first support rod 31 and the first counterweight 32, and the second mounting ring 2 can be supported by the second support rod 61 and the second counterweight 62 to reduce the load of the lifting device and improve the stability during the lifting process. Repeat the above steps to complete the construction of the concrete silo; When the first mounting ring 1 and the second mounting ring 2 are lifted to a certain height, personnel are required to build a working platform to polish the outer wall of the silo. The first motor 53 drives the second rotating shaft 51 to rotate, driving the first support rod 31 to rotate to the second position, so that the first support rod 31 is perpendicular to the first vertical rod 222. A first working board 312 is laid on the first support rod 31 for personnel to stand and work.
