Description

Technical Field

[0001] This utility model relates to the field of tunnel construction technology, specifically an automatic cleaning system for concrete placing booms. Background Technology

[0002] Tunnel lining trolleys typically use concrete placing booms to pour formwork, followed by manual cleaning. However, manual cleaning is generally ineffective.

[0047] Example 1

[0048] like Figure 1 The present embodiment discloses an automatic cleaning system for a fabric laying machine (hereinafter referred to as "cleaning system"), which mainly includes a water supply component 1, a water supply pipeline 2, and a first cleaning unit. The first end of the water supply pipeline 2 is connected to the water supply component 1, wherein the water supply component 1 is specifically a water pump, and a water control valve 3 and a water safety valve 4 are provided on the water supply pipeline 2.

[0049] Typically, a complete set of concrete placing booms consists of a central main placing boom 11 and two side placing booms 12 on either side. Figure 2 As shown, where Figure 2The diagram only shows the side placing boom 12 on one side. During the formwork pouring process, the concrete pump truck first pumps concrete into the main placing boom 11. The side formwork of the lining trolley has multiple pouring ports. The side placing boom 12 first moves to one pouring port, rotates and / or extends the placing boom 13 on the side placing boom 12, and pushes the rubber prongs 1301 on the placing boom 13 against the placing flared end 14 of the side formwork. Subsequently, the main placing boom 11 also moves to the corresponding position of the side placing boom 12, rotates and / or extends the placing boom 13 on the main placing boom 11, so that the rubber prongs 1301 on the placing boom 13 push against the placing flared end 14 of the side placing boom 12. This completes the establishment of the concrete channel, and then the concrete from the concrete pump truck can enter the space between the trolley formwork and the rock wall to complete the formwork pouring. The collection trough 15 is located below each placing boom 14, and its function is to collect some of the falling concrete when the rubber head 1301 separates from the placing boom 14. The placing boom 14 of the formwork arch is directly connected to the placing boom 13 of the main placing machine 11.

[0050] Based on the above-described concrete placing process of the entire placing boom, it is known that the cleaning system needs to clean the following parts: the rubber tips 1301 of the placing boom 13 on the main placing boom 11 and the side placing boom 12; the placing nozzle 14 on the side placing boom 12 and the trolley template; and the collection trough 15 below the placing nozzle 14. In this embodiment, a first cleaning unit and a second cleaning unit are arranged on the placing boom 13. The first cleaning unit is used to clean the residual concrete on the placing nozzle 14 and the rubber tips 1301, and the second cleaning unit is used to clean the residual concrete in the collection trough 15. For example... Figure 1 As shown, there are a total of 3 first cleaning units and 4 second cleaning units. The main placing boom 13 has 1 cleaning unit and 2 second cleaning units. The 2 cleaning units are used to clean the material collection troughs 15 on the left and right side placing booms 12, respectively. The placing booms 13 of the two side placing booms 12 each have 1 first cleaning unit and 1 second cleaning unit.

[0051] It is worth noting that the assembly and application of the first and second cleaning units can be adjusted according to actual needs during specific applications. For example, the first and / or second cleaning units can be arranged only on the boom 13 of the main placing boom 11, or only on the boom 13 of one or two side placing booms 12, or simultaneously on the boom 13 of both the main placing boom 11 and the side placing booms 12. Figure 3As shown, only one cleaning unit and two second cleaning units are installed on the placing boom 13 of the main placing boom 11. In this case, the cleaning system is only used to clean the rubber tips 1301 on the main placing boom 11 and the placing bell 14 and collecting trough 15 on the side placing boom 12. When the first and second cleaning units are located on the main placing boom 11, they move with the main placing boom 11. When the first and second cleaning units are located on the side placing boom 12, they move with the side placing boom 12.

[0052] In this embodiment, the first cleaning unit includes a first cleaning component 5, a first cleaning pipe 6, and a first control valve 7. The first cleaning component 5 is fixedly mounted on the fabric end of the fabric arm 13, and has a first nozzle 503 facing the same direction as the fabric end of the fabric arm 13. The first cleaning component 5 is connected to the second end of the water supply pipe 2 through the first cleaning pipe 6, and the first control valve 7 is mounted on the first cleaning pipe 6 to control the on / off state of the first cleaning pipe 6.

[0053] refer to Figure 4 The first cleaning assembly 5 includes a first cleaning pipe component 501 with closed ends, and ear plates 502 are provided at both ends of the first cleaning pipe component 501. The ear plates 502 are detachably connected to the fabric arm 13 by bolts. The top of the first cleaning pipe component 501 is provided with multiple first nozzles 503, and the bottom of the first cleaning pipe component 501 is provided with an inlet internal threaded pipe clamp 504, which is connected to the first cleaning pipe 6. Preferably, the first cleaning pipe component 501 has an arc-shaped structure, and multiple first cleaning pipe components 501 are connected circumferentially to the fabric end of the fabric arm 13, thereby forming a spray ring at the fabric end of the fabric arm 13. Figure 5 As shown. More preferably, there is an elbow 505 between the first nozzle 503 and the first cleaning pipe fitting 501, so that the first nozzle 503 is oriented toward the center of the fabric end of the fabric arm 13, so that the cleaning water sprayed by the first nozzle 503 is directed toward the closing direction of the fabric flare 14, thereby effectively improving the cleaning efficiency.

[0054] refer to Figure 6After the formwork pouring is completed, the rubber tip 1301 on the placing boom 13 detaches from the placing bell mouth 14, maintaining a certain distance, such as 10mm, between the rubber tip 1301 and the placing bell mouth 14. Then, the water control valve 3 and the corresponding first control valve 7 are opened, causing the first cleaning pipe fitting 501 to spray cleaning water towards the placing bell mouth 14, thereby cleaning the residual concrete on the placing bell mouth 14. Simultaneously, because the placing bell mouth 14 and the rubber tip 1301 on the placing boom 13 are close together during the cleaning process, the cleaning water can bounce between the placing bell mouth 14 and the rubber tip 1301, achieving the effect of cleaning both the placing bell mouth 14 and the rubber tip 1301 simultaneously, effectively improving cleaning efficiency.

[0055] In this embodiment, the second cleaning unit includes a second cleaning assembly 8, a second cleaning pipe 9, and a second control valve 10. The second cleaning assembly 8 is fixedly mounted on the side of the fabric arm 13, and has a second nozzle 802 facing the side of the fabric arm 13. The second cleaning assembly 8 is connected to the second end of the water supply pipe 2 through the second cleaning pipe 9, and the second control valve 10 is mounted on the second cleaning pipe 9 to control the on / off state of the second cleaning pipe 9.

[0056] refer to Figures 5 to 7 The second cleaning assembly 8 includes a second cleaning pipe component 801 with one open end. The second cleaning pipe component 801 is detachably connected to the side of the fabric boom 13, and its length direction is parallel to the fabric boom 13. Multiple second nozzles 802 are spaced apart along the length direction on the side of the second cleaning pipe component 801, and the open end of the second cleaning pipe component 801 is connected to the second cleaning pipe 9. The side of the fabric boom 13 is provided with an outwardly extending connecting plate 1302. The second cleaning pipe component 801 is provided with a mounting plate 803. The connecting plate 1302 has a first mounting hole, and the mounting plate 803 has a second mounting hole. The mounting plate 803 and the connecting plate 1302 are detachably connected via bolts that mate with the first and second mounting holes. The second mounting hole is a waist-shaped hole, and the length direction of the second mounting hole is parallel to the extension direction of the connecting plate 1302 on the side of the fabric boom 13. This allows the position of the second cleaning pipe component 801 on the fabric boom 13 to be finely adjusted, thereby changing the coverage point of the water flow during cleaning to ensure accurate cleaning position.

[0057] It is worth noting that, in specific applications, for concrete placing machines that do not have a material collection trough 15, the second cleaning unit may be omitted from the cleaning system.

[0058] Example 2

[0059] like Figure 8The figure shown is an automatic cleaning system for a fabric laying machine (hereinafter referred to as "cleaning system") disclosed in this embodiment. Its implementation method is basically the same as that of Embodiment 1, except that:

[0060] The cleaning system in this embodiment also includes an air supply component and an air supply pipeline 16. The first end of the air supply pipeline 16 is connected to the air supply component, which consists of an air compressor 17 and an air storage tank 18. The air compressor 17 and the air storage tank 18 are mounted on the lining trolley and move with the trolley. The air storage tank 18 has a capacity of 600L or more and serves to store and maintain pressure. An air supply control valve 19 is installed on the air supply pipeline 16, and an air supply safety valve 20 is installed on the air storage tank 18. When the cleaning system has only a first cleaning unit, the first cleaning component 5 is connected to the second end of the air supply pipeline 16 through the first cleaning pipe 6. When the cleaning system has both a first cleaning unit and a second cleaning unit, the first cleaning component 5 is connected to the second end of the air supply pipeline 16 through the first cleaning pipe 6, and the second cleaning component 8 is connected to the second end of the air supply pipeline 16 through the second cleaning pipe 9.

[0061] During the cleaning process, the cleaning system can first spray water to loosen the concrete, and then use high-pressure air to clean the concrete. Alternatively, it can directly use high-pressure air to clean the residual concrete, or it can use a water-air mixture to rinse, with high-pressure water and high-pressure air being flushed out simultaneously.

[0062] The above description is only a preferred embodiment of the present utility model and does not limit the scope of protection of the present utility model.
