Description

Technical Field

[0001] This utility model relates to the technical field of manhole cover production equipment, and in particular to a reinforced concrete manhole cover production equipment. Background Technology

[0002] Existing concrete manhole cover production equipment such as Figure 1 As shown, the device includes a vibration device 10. During production, the bottom mold 20 is placed on the vibration platform 11 on top of the vibration device 10. Then, the manhole cover mold frame 30 is placed on the bottom mold 20, and the upper mold cover 40 is placed on the manhole cover mold frame 30. After that, two crossbeams 50 are placed on the upper mold cover 40. The two ends of the crossbeams 50 are provided with grooves. The screw clamping device 12 hinged on both sides of the vibration platform 11 is engaged in the grooves. The crossbeams 50 are pressed down by the handle above, thereby fixing the upper mold cover 40, the manhole cover mold frame 30 and the bottom mold 20 to the vibration platform 11. The drawbacks of the above structure are as follows: Since the bottom mold 20 is placed on the vibration platform 11, after the concrete filling and vibration of a manhole cover are completed, the crossbeam 50 and the upper mold cover 40 are removed first. Then, the manhole cover frame 30 and the concrete inside the manhole cover frame 30 need to be transported and lifted out through the bottom mold 20. To facilitate transportation, the bottom mold 20 needs to extend beyond the vibration platform 11 to provide hand gripping space. In other words, the width of the bottom mold 20 needs to be greater than the width of the vibration platform 11. However, when transporting the bottom mold 20 and the manhole cover frame 30 to the ground for concrete curing, the bottom mold 20 requires a significant amount of ground area. In addition, since the bottom of the bottom mold 20 lacks a supporting structure, fingers are difficult to remove when placed on the ground. During operation, additional wooden blocks are needed to support the bottom mold 20, causing inconvenience to production. Utility Model Content

[0003] The purpose of this utility model is to provide a reinforced concrete manhole cover production equipment. By setting a through lifting channel on the vibrating platform and installing a lifting device on the base of the vibrating device, the bottom mold is lifted by the lifting device, which makes it easy to transport. In this way, the size of the bottom mold only needs to be slightly larger than the size of the manhole cover mold frame, which can reduce the area of ​​the ground occupied by the bottom mold.

[0004] To achieve the above objectives, this utility model provides a reinforced concrete manhole cover production equipment, including a vibration device. The vibration platform of the vibration device is provided with a through lifting channel, and a lifting device is installed on the base of the vibration device. In use, the lifting device extends into the lifting channel to lift objects on the vibration platform.

[0005] It also includes a bottom mold, on the lower side of which at least two support blocks are installed. The number and position of the lifting channel correspond to the number of support blocks, and the support blocks are used to be placed in the lifting channel.

[0006] The support block is elongated and narrow at the bottom of its cross-section, while the upper end of the lifting channel has a wedge-shaped structure that is wider at the top and narrower at the bottom.

[0007] A limiting groove is provided in the upper middle part of the bottom mold.

[0008] The lifting device is one of a hydraulic cylinder, a pneumatic cylinder, or an electric cylinder.

[0009] An extension rod is installed at the end of the telescopic rod of the lifting device.

[0010] The lower end of the lifting channel has a trumpet-shaped structure that is narrower at the top and wider at the bottom.

[0011] The base of the vibration device is fixedly installed with a support beam, and the lifting device is installed on the support beam.

[0012] Compared with the prior art, this utility model has the following technical effects:

[0013] 1. This utility model sets a through lifting channel on the vibration platform and installs a lifting device on the base of the vibration device. After the bottom mold is lifted by the lifting device, it is easy to transport. In this way, the size of the bottom mold only needs to be slightly larger than the size of the manhole cover mold frame, which can reduce the area of ​​the ground occupied by the bottom mold.

[0014] 2. The bottom mold of this utility model is equipped with a support block on its lower side. When the bottom mold is placed on the ground, the support block supports the ground, eliminating the need to place wooden blocks, making the operation more convenient. In addition, by setting the support block, the bottom mold and the vibration platform can be limited to prevent displacement during vibration.

[0015] 3. An extension rod is installed and connected to the end of the telescopic rod of the lifting device of this utility model. In this way, when lifting the bottom formwork, there will be no problem of friction between the telescopic rod of the lifting device and the lifting channel, which would cause damage to the telescopic rod of the lifting device.

[0016] 4. The base of the vibration device of this utility model is fixedly installed with a support beam, which provides installation space for the lifting device. Attached Figure Description

[0034] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0035] Example 1:

[0036] Please see Figure 2-9A reinforced concrete manhole cover production equipment includes a vibrating device 10, a vibrating platform 11 of the vibrating device 10 with a through lifting channel 111, and a lifting device 60 mounted on the base 13 of the vibrating device 10. In use, the lifting device 60 extends into the lifting channel 111 to lift objects on the vibrating platform 11. By providing a through lifting channel 111 on the vibrating platform 11 of the vibrating device 10 and mounting the lifting device 60 on the base 13 of the vibrating device 10, the bottom mold 20 can be lifted by the lifting device 60, facilitating transportation. The size of the bottom mold 20 only needs to be slightly larger than the size of the manhole cover mold frame 30, thereby reducing the ground area occupied by the bottom mold.

[0037] In this embodiment, the lifting channel 111 can be a circular hole located at the center of the vibration platform 11. The vibration device 10 adopts a hydraulic cylinder, and a support plate is fixedly installed at the end of the piston rod of the hydraulic cylinder. When the piston rod of the hydraulic cylinder extends, the support plate extends into the lifting channel 111, which can lift the bottom mold 20. After being lifted, it is easy for a person to grip.

[0038] The through-type lifting channel 111 also facilitates the cleaning of concrete left on the vibration platform 11.

[0039] Example 2:

[0040] The difference from Example 1 is that, see [link to example]. Figure 2 , 5 6. In this embodiment, a bottom mold 20 is also included. At least two support blocks 21 are installed on the lower side of the bottom mold 20. The number and position of the lifting channel 111 correspond to those of the support blocks 21, and the support blocks 21 are used to be placed inside the lifting channel 111. The above structure has the following advantages: First, with the support blocks 21, when the bottom mold 20 is placed on the ground, the support blocks 21 support the ground, eliminating the need to place wooden blocks, making the operation more convenient; Second, by setting the support blocks 21, the bottom mold 20 and the vibration platform 11 can be limited to prevent displacement during vibration.

[0041] For details, see Figure 6 Two support blocks 21 are fixedly installed on the lower side of the bottom mold 20; see Figure 3 , 4 The vibration platform 11 is equipped with two lifting channels 111, and the support block 21 is positioned corresponding to the lifting channel 111.

[0042] For easier placement of the bottom mold 20, see [link / reference] Figure 6 and Figure 4 The support block 21 is long and narrow, with a cross-section that is wider at the top and narrower at the bottom. The upper end of the lifting channel 111 is a wedge-shaped structure 112 that is wider at the top and narrower at the bottom.

[0043] Furthermore, a limiting groove 22 is provided on the upper middle part of the bottom mold 20 to facilitate the limiting of the manhole cover mold frame 30.

[0044] When in use, the manhole cover mold frame 30 is placed in the limiting groove 22.

[0045] Specifically, the limiting groove 22 can be formed by slotting the bottom mold 20, or it can be formed by fixing the frame to the upper side of the bottom mold 20.

[0046] Example 3:

[0047] Based on Embodiment 1 or Embodiment 2, the lifting device 60 is one of a hydraulic cylinder, a pneumatic cylinder, or an electric cylinder.

[0048] See Figure 8 An extension rod 61 is installed and connected to the end of the telescopic rod of the lifting device 60. This prevents the telescopic rod of the lifting device 60 from rubbing against the lifting channel 111 when lifting the bottom mold 20, thus avoiding damage to the telescopic rod of the lifting device 60.

[0049] Specifically, the lower end of the extension rod 61 is provided with a threaded hole, and the extension rod 61 is screwed and fixed to the end of the telescopic rod of the lifting device 60 by threaded engagement.

[0050] Further, see Figure 4 To prevent the lifting channel 111 from being misaligned due to spring deformation, the lower end of the lifting channel 111 is a trumpet-shaped structure 113 that is narrow at the top and wide at the bottom.

[0051] See Figure 7 , 8 A support beam 131 is fixedly installed inside the base 13 of the vibration device 10, and the lifting device 60 is installed on the support beam 131. The base 13 has a frame structure, and the support beam 131 is welded inside the base 13, providing installation space for the lifting device 60.

[0052] In this embodiment, four lifting devices 60 are provided to balance the lifting of the bottom mold 20.

[0053] The working principle or operation process of this utility model is as follows:

[0054] See Figure 2 The vibration platform 11 is mounted on the base 13 by multiple spring supports, and a vibration motor is installed on the lower side of the vibration platform 11. After a manhole cover is filled with concrete and vibrated, the crossbeam 50 and the upper mold cover 40 are removed.

[0055] See Figure 9The telescopic rod of the lifting device 60 is extended, and the extension rod 61 extends into the lifting channel 111, lifting the bottom mold 20 to a certain height. This provides hand gripping space around the bottom mold 20, facilitating its handling. Afterward, the telescopic rod of the lifting device 60 is retracted, and the extension rod 61 leaves the lifting channel 111. The extension rod 61 does not affect the vibration of the vibration platform 11.
