Description

Technical Field

[0001] This utility model particularly relates to a molding device for a manhole cover installation auxiliary tool. Background Technology

[0002] When installing manhole covers, 3-4 concrete blocks or machine-made bricks are typically used, covered with dry-hardened cement mortar, and leveled according to the road surface elevation to ensure the stability and flatness of the manhole cover. Furthermore, using cement blocks (i.e., installation aids) can effectively adjust the elevation of the manhole cover, ensuring it is flush with the road surface and preventing unevenness. Existing concrete blocks have the following problems in their production process: First, cement, aggregates, water, additives, and other raw materials are mixed evenly, then poured into specific molds. Manual filling of the molds is inefficient, resulting in uneven compaction, air bubbles, or material shortages. Reliance on manual leveling and demolding leads to poor dimensional accuracy of the blocks, affecting the accuracy of the manhole cover reinforcement positioning. Existing equipment cannot achieve continuous production, resulting in low production efficiency. Utility Model Content

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a forming device for a manhole cover installation auxiliary tool.

[0004] To solve the aforementioned technical problems, this utility model adopts the following technical solution:

[0005] A forming device for a manhole cover installation auxiliary tool includes a frame and a raw material silo for holding a cement mixture. A conveying device is installed on the frame, and a mold is connected to the conveying device. The frame is sequentially arranged along the conveying direction with a left pressing mechanism for initial compaction of the material in the mold, a leveling mechanism for scraping off excess material from the mold opening and leveling the surface, and a right pressing mechanism for secondary compaction of the leveled material. In the initial state, the mold opening faces upward. After the material is injected, the mold is conveyed by the conveying device and sequentially pressed by the left pressing mechanism, leveled by the leveling mechanism, and then pressed again by the right pressing mechanism. The conveying device continues to convey the mold so that the mold flips over so that the opening faces downward.

[0006] Preferably, both the left pressing mechanism and the right pressing mechanism include a mounting bracket fixed on the frame, a hydraulic cylinder is connected to the mounting bracket, and a pressing block is connected to the hydraulic cylinder.

[0007] Preferably, the leveling mechanism includes a fixed frame mounted on a machine frame, and a scraper is connected to the fixed frame.

[0008] Preferably, the conveying device includes drive rollers symmetrically arranged on the frame, a first conveyor belt and a second conveyor belt are wound parallel to each other between the two drive rollers, a plurality of fixed plates for mounting the mold are fixedly arranged between the first conveyor belt and the second conveyor belt, and a rotary motor is connected to any one of the drive rollers. The rotary motor is used to drive the first conveyor belt and the second conveyor belt to rotate synchronously, so that the mold can complete the flipping action from opening upward to opening downward during the movement.

[0009] Preferably, an elastic support structure is provided below the conveying device to receive the cement pad after demolding.

[0010] Preferably, the elastic support structure includes fixed rollers symmetrically arranged on the frame, a receiving belt is wound between the two fixed rollers, and at least one tensioning roller is arranged between the two fixed rollers to maintain the tension of the receiving belt.

[0011] The beneficial effects of this utility model are:

[0012] The molding equipment described in this application ensures initial compaction of the material by a left pressing mechanism, while a right pressing mechanism eliminates internal voids that may be caused by leveling, resulting in uniform density of the blocks. A conveyor device drives the mold through each station sequentially, eliminating the need for manual intervention and improving work efficiency. Furthermore, after the mold is flipped so that the opening faces downwards, the blocks can be easily detached by a light tap, reducing breakage compared to manual prying. This pioneering 'double compaction + leveling' process, combined with automated flipping and demolding, not only solves industry problems such as uneven density and poor dimensional accuracy of cement blocks, but also achieves breakthroughs in both production efficiency and yield. It is particularly suitable for manhole cover installation scenarios where stringent requirements for rebar positioning accuracy are present. Attached Figure Description

[0022] A forming device for manhole cover installation auxiliary tools, referring to Figures 1-3 The system includes a frame 1 and a raw material silo 2 for holding cement mixtures. The frame 1 is equipped with a conveying device, and a mold 3 is connected to the conveying device. Along the conveying direction, the frame 1 is sequentially equipped with a left pressing mechanism 4 for initial compaction of the material in the mold 3, a scraping mechanism 5 for scraping off excess material from the opening of the mold 3 and leveling the surface, and a right pressing mechanism 6 for secondary compaction of the leveled material. In the initial state, the mold 3 has its opening facing upward. After the material is injected, the mold 3 is conveyed by the conveying device and sequentially pressed by the left pressing mechanism 4, the scraping mechanism 5, and the right pressing mechanism 6. The conveying device continues to convey the mold 3 so that the mold 3 flips to have its opening facing downward.

[0023] Furthermore, both the left pressing mechanism 4 and the right pressing mechanism 6 include a mounting bracket 41 fixed to the frame 1, a hydraulic cylinder 42 connected to the mounting bracket 41, and a pressing block 43 connected to the hydraulic cylinder 42.

[0024] Furthermore, the leveling mechanism 5 includes a fixed frame 51 mounted on the frame 1, and a scraper 52 is connected to the fixed frame 51.

[0025] Furthermore, the conveying device includes drive rollers 71 symmetrically arranged on the frame 1, with a first conveyor belt 72 and a second conveyor belt 73 wound parallel between the two drive rollers 71. A plurality of fixed plates 74 for mounting the mold 3 are fixedly arranged between the first conveyor belt 72 and the second conveyor belt 73. A rotary motor 75 is connected to any drive roller 71. The rotary motor 75 is used to drive the first conveyor belt 72 and the second conveyor belt 73 to rotate synchronously, so that the mold 3 can complete the flipping action from opening upward to opening downward during the movement.

[0026] Furthermore, an elastic support structure for receiving the cement pad 8 after demolding is provided below the conveying device.

[0027] Furthermore, the elastic support structure includes fixed rollers 91 symmetrically arranged on the frame 1, a receiving belt 92 is wound between the two fixed rollers 91, and at least one tensioning roller 93 is arranged between the two fixed rollers 91 to maintain the tension of the receiving belt 92.

[0028] The working principle of this utility model is as follows:

[0029] This application uses cement blocks as an example to illustrate the design concept of this application. When producing cement blocks 8, the opening of the mold 3 faces upward in the initial state. The raw material hopper 2 fills the mold 3 with material. When the conveying device conveys the mold 3, since the left pressing mechanism 4, the scraping mechanism 5, and the right pressing mechanism 6 are arranged sequentially along the conveying direction on the frame 1, when the mold 3 moves along the conveying direction, the left pressing mechanism 4 performs the first compaction of the material in the mold 3. After the first compaction, the scraping mechanism 5 scrapes off the excess material at the opening of the mold 3 and flattens the surface. Then, under the action of the right pressing mechanism 6, the material is compacted a second time. Then, it needs to stand for about 24 hours. After molding, the conveying device continues to convey the mold 3 so that the mold 3 flips to face downward. At this time, the mold 3 is tapped so that the block is removed from the mold 3.

[0030] Based on this technical solution, the design of the left pressing mechanism 4 and the right pressing mechanism 6 can both be designed with a mounting frame 41 fixedly installed on the frame 1. A hydraulic cylinder 42 is connected to the mounting frame 41, and a pressing block 43 is connected to the hydraulic cylinder 42. The hydraulic cylinder 42 drives the pressing block 43 to move up and down, so that the pressing block 43 compacts the material. The structure of the scraper 52 mechanism can be designed with a fixed frame 51 connected to the frame 1, and a scraper 52 connected to the fixed frame 51. Taking the conveying device as an example, with a first conveyor belt 72 and a second conveyor belt 73 running parallel between two transmission rollers 71, multiple fixed plates 74 for mounting the mold 3 are spaced apart between the first conveyor belt 72 and the second conveyor belt 73. When the motor drives the transmission rollers 71 to rotate, the first conveyor belt 72 and the second conveyor belt 73 rotate synchronously to move the mold 3. When the mold 3 moves to each station and stops, it refers to the left pressing mechanism 4, the scraper 52 mechanism, and the right pressing mechanism 6, thereby completing the compaction and scraping operations.

[0031] Based on the above technical solution, this application also provides an elastic support structure below the conveying device. Taking two fixed rollers 91 spaced apart on the frame 1 as an example, a receiving belt 92 is wound between the two fixed rollers 91, and at least one tensioning roller 93 is provided between the two fixed rollers 91 to maintain the tension of the receiving belt 92. When the cement block 8 falls from the flipped mold 3 and impacts the belt in free fall, the elastic deformation of the receiving belt 92 can absorb the impact energy, reducing the risk of the block breaking. In addition, the tensioning roller 93 can dynamically adjust the belt tension to ensure that blocks of different weights receive optimal cushioning when falling, preventing the blocks from accumulating or shifting due to belt slack.

[0032] The molding equipment described in this application performs initial compaction by the left pressing mechanism 4, ensuring the material is initially compacted. The right pressing mechanism 6 then performs secondary compaction to eliminate internal voids that may be caused by leveling, resulting in uniform density of the cement blocks. The conveying device drives the mold 3 through each station sequentially, eliminating the need for manual intervention and improving work efficiency. Furthermore, after the mold 3 is flipped so that the opening faces downwards, the blocks can be easily detached by a light tap, reducing breakage compared to manual prying. This innovative 'double compaction + leveling' process, combined with automated flipping and demolding, not only solves industry problems such as uneven density and poor dimensional accuracy of the cement blocks 8, but also achieves breakthroughs in both production efficiency and yield. It is particularly suitable for manhole cover installation scenarios where stringent requirements for rebar positioning accuracy are present.

[0033] Although the present invention has been described in detail with reference to the above embodiments, it will be apparent to those skilled in the art that various changes or modifications can be made to the present invention without departing from the principles and spirit of the present invention as defined by the claims. Therefore, the detailed description of the embodiments in this disclosure is for explanation only and not for limiting the present invention, but rather the scope of protection is defined by the content of the claims.
