Description

Technical Field

[0001] The utility model relates to the field of channel component production equipment, in particular to a concrete channel component forming machine. Background Art

[0002] Concrete channel components are made of suitable raw materials such as cement, sand and gravel aggregates, which are mixed evenly in a certain proportion and poured into a pre-designed mold. The concrete is vibrated to make it dense and finally cured to ensure that the concrete reaches the designed strength.

[0003] China's authorization announcement number CN202037693U discloses a concrete channel component forming machine. Its purpose is to provide a concrete channel component forming machine with simple processing and flexible replacement of inner molds. The specific technical solution of the utility model is: a concrete channel component forming machine, which includes a vibrator, a machine base, an outer mold fixed on the machine base, and an inner mold compatible with the outer mold. A frame is fixed on the machine base, a machine head is fixed on the machine frame, a pressure head device is installed on the machine head, and an inner mold cylinder is also installed on the machine head. The output shaft of the inner mold cylinder is connected to a connecting plate I, and the connecting plate I is mounted on the inner mold guide rod fixed on the machine base. A connecting plate II is provided on the inner mold to connect with the connecting plate I. The beneficial effects of the utility model are: simple structure, low processing precision requirements, and easy processing; convenient and flexible replacement of inner molds of various specifications and shapes; wide range of application of the equipment, suitable for the processing of various types of channel components.

[0004] However, this device has the following drawbacks: 1. Because most concrete channel components are V- and U-shaped, the mold cavity is small, which can easily cause concrete to spill out of the mold during loading. 2. Because the device only has a vibrator on the base, it is difficult to quickly expel concrete voids and bubbles within the mold, which can easily cause honeycombing and affect production quality. To address these drawbacks, we propose a concrete channel component forming machine. Utility Model Content

[0020] 1. By setting up a loading structure, when concrete is transported to the top of the lower mold, the material will first enter the material retaining frame for collection, and then the slope plate in the material retaining frame will evacuate the material, so that it will be dispersed along the leakage chute and fall into the lower mold. Compared with the existing technology, this device uses the material retaining frame to prevent the concrete from scattering outside the lower mold, and at the same time cooperates with the slope plate to evacuate the concrete entering the material retaining frame, so as to prevent it from clogging the leakage chute, so that the material can quickly enter the lower mold.

[0034] The guide component comprises a guide rod 15 fixedly installed on the inner wall of the base 10 and a guide block 16 slidably installed on the inner wall of the guide rod 15. The upper surface of the guide rod 15 and the upper surface of the nut seat 13 are fixedly connected with the lower surface of the concrete vibrating table 11. The movement track of the concrete vibrating table 11 can be guided by the cooperation of the guide rod 15 and the guide block 16. The driving motor 14 can drive the lead screw 12 to rotate, and the lead screw 12 and the nut seat 13 are screw-connected, so that the concrete vibrating table 11 can be driven to move.

[0035] Please refer to Figure 4-5 The loading structure is arranged above the base 10 and comprises a lower mould 20, a hopper fixedly installed on the upper surface of the lower mould 20, a limiting assembly arranged between the concrete vibrating table 11 and the lower mould 20, and a concrete vibrating assembly arranged on the upper surface of the base 10.

[0036] The limiting assembly includes a limiting pin 60 fixedly mounted on the upper surface of the concrete vibrating table 11, and a limiting block 61 fixedly mounted on the surface of the lower mold 20, and a limiting groove for inserting the limiting pin 60 is provided on the surface of the limiting block 61. When the limiting pin 60 is inserted into the limiting groove on the limiting block 61, the lower mold 20 can be limited on the concrete vibrating table 11.

[0037] See Figure 6 The hopper includes a material blocking frame 30 fixedly mounted on the upper surface of the lower mold 20, and a ramp plate 31 fixedly mounted on the inner wall of the material blocking frame 30. A material leakage trough 32 is provided between the material blocking frame 30 and the ramp plate 31, and the material leakage trough 32 is adapted to the cavity of the lower mold 20.

[0038] When concrete is delivered to the top of the lower mold 20, the material will first enter the blocking frame 30 for collection, and then the ramp plate 31 in the blocking frame 30 will evacuate the material, so that it will be dispersed along the leakage chute 32 and fall into the lower mold 20. Compared with the existing technology, the device uses the blocking frame 30 to collect and block the concrete, which can prevent the concrete from scattering outside the lower mold 20. At the same time, the ramp plate 31 can be used to evacuate the concrete entering the blocking frame 30, which can prevent it from clogging the leakage chute 32, so that the material can quickly enter the lower mold 20.

[0039] See Figure 1 and Figure 3 The concrete vibration assembly includes a first support frame 40 fixedly mounted on the upper surface of the base 10, a first cylinder 41 fixedly mounted on the inner top wall of the first support frame 40, a mounting plate 42 fixedly mounted on the telescopic end of the first cylinder 41, and a concrete vibration rod 43 fixedly mounted on the lower surface of the mounting plate 42.

[0040] After the concrete filling in the lower mold 20 is completed, the first cylinder 41 is driven to drive the concrete vibrating rod 43 to descend and enter the lower mold 20, so that the concrete vibrating rod 43 can be used to vibrate the concrete in the lower mold 20 to make its aggregate more compact. At the same time, the concrete vibrating table 11 located below the lower mold 20 can vibrate the lower mold 20 again, so that the concrete in the lower mold 20 can be vibrated efficiently, thereby effectively reducing the vibration time, accelerating the discharge of bubbles, and reducing the phenomenon of honeycomb surface of the channel structure after demoulding.

[0041] See Figure 1 、 Figure 2 and Figure 4 The demolding structure includes a second support frame 50 fixedly mounted on the upper surface of the base 10 , an extrusion assembly arranged on the top wall of the second support frame 50 , and a mold lifting assembly arranged on the inner wall of the second support frame 50 .

[0042] The extrusion assembly includes a second cylinder 70 fixedly mounted on the inner top wall of the second support frame 50 , and an upper mold 71 fixedly mounted on the lower surface of the second cylinder 70 , and the upper mold 71 is adapted to the cavity of the lower mold 20 .

[0043] After the concrete in the lower mold 20 is vibrated and compacted, the first cylinder 41 will reset and drive the concrete vibrating rod 43 to reset. Then, the driving assembly will drive the concrete vibrating table 11 to move to the bottom of the second support frame 50. Then, the second cylinder 70 will be driven down to drive the upper mold 71 into the lower mold 20 and squeeze the concrete again.

[0044] The mold lifting assembly includes a third cylinder 80 fixedly mounted on the inner top wall of the second support frame 50, a pin 81 fixedly mounted on the telescopic end of the third cylinder 80, and an insert block 82 fixedly mounted on the surface of the material blocking frame 30, and a hole for inserting the pin 81 is provided on the surface of the insert block 82, and the pin 81 is located below the insert block 82.

[0045] When the driving assembly drives the concrete vibrating table 11 to move to the bottom of the second support frame 50, the pin 81 is located under the socket. When the extrusion assembly drives the upper mold 71 to squeeze the concrete in the lower mold 20, the third cylinder 80 is driven to drive the pin 81 to move upward and insert it into the socket, so that the lower mold 20 can be lifted. The upper mold 71 can be used to limit the concrete to prevent the concrete from rising synchronously with the lower mold 20 when the lower mold 20 is lifted, so that rapid demoulding can be performed, which is convenient for the operator to take the material. When the lower mold 20 is lifted upward, the limit groove will disengage from the limit pin 60. When the material is taken, the third cylinder 80 will reset and drive the limit pin 60 to reinsert into the limit groove, so that the lower mold 20 can be limited again.

[0046] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited thereto. Any equivalent replacement or change made by a person skilled in the art based on the technical solution and concept of the present invention should be included in the protection scope of the present invention.
