[0006] Preferably, the connecting devices are arranged in an array.

[0007] Preferably, the anti-falling device is a limit block, and the limit block is rotatably connected to the baffle.

[0008] Preferably, a blocking plate is provided between the counterweight area and the discharge area to prevent concrete from contaminating the counterweight area.

[0009] Preferably, the reinforcement device is a tension bolt, and the tension bolt is connected to the baffle.

[0010] A method for efficiently conveying secondary structure concrete, using a detachable tool for efficiently conveying secondary structure concrete to convey the secondary structure concrete, specifically comprising the following steps: Step 1: Determine the diameter of the reserved hole according to the concrete pumping volume, select the blanking plate, connect the blanking plate with the bottom plate, and connect the corrugated pipe with the reserved hole; Step 2: Place a detachable tool for efficient secondary structural concrete delivery on the upper outer wall or opening area, place a counterweight block in the counterweight area, and then use tension bolts and wooden squares to install the detachable tool for efficient secondary structural concrete delivery on the main structure of the building; Step 3: The concrete truck unloads the concrete to the discharge area through the bucket truck, and then pushes the concrete from the discharge area to the discharge plate and enters the reserved holes.

[0011] Preferably, if the detachable tool for efficient secondary structure concrete transportation in step 2 is placed in the outer wall area, the counterweight area is stabilized by gravity toward the interior, the blanking plate is cantilevered toward the outside, and the corrugated pipe falls through the outer wall space to the lower construction pouring site.

[0012] Preferably, if the detachable tool for efficient secondary structure concrete transportation in step 2 is placed in the reserved hole area, it falls directly above the hole and is stabilized by a counterweight device, wherein the corrugated pipe is aligned with the hole and falls to the lower construction pouring site.

[0013] The effects provided in the summary of the invention are only the effects of the embodiments, rather than all the effects of the invention. The above technical solution has the following advantages or beneficial effects: 1. By designing the blanking plate to be detachable, the diameter of the reserved hole can be accurately determined according to the concrete pumping volume to select the blanking plate, ensuring a reasonable flow rate and stable flow rate of concrete in the conveying link, avoiding the problem of uncontrolled concrete pouring due to excessively large holes, or pumping blockage and slow flow rate due to too small holes, so that concrete can flow into the corrugated pipe continuously and efficiently, speeding up the pouring process of the secondary structure and greatly reducing the construction time; 2. The tool of the present invention can be placed in the outer wall area, and stabilize itself by using the gravity characteristics of the counterweight area facing the room, so that the blanking plate can be smoothly cantilevered and the corrugated pipe can accurately pass through the outer wall space; it can also be placed in the reserved hole area and quickly positioned with the help of the counterweight device, eliminating the complicated on-site construction and adjustment process. The construction personnel can quickly carry out the pouring work, reduce the time-consuming process connection, and improve the overall construction rhythm; 3. The blocking plates between the counterweight area and the material discharge area effectively isolate the concrete from the counterweight area, preventing concrete from scattering and leaking and contaminating the counterweight block and the surrounding area. On the one hand, the original weight and performance of the counterweight block are maintained to ensure the stability of the tool's center of gravity; on the other hand, the accumulation of debris and residual concrete stains on the construction site are reduced, which is conducive to maintaining a clean site, meeting civilized construction standards, and indirectly improving the overall construction quality; 4. After the pouring is completed, the main parts of the tool of the present invention, such as the bottom plate and the blanking plate, can be kept for use after simple cleaning. If the bellows is properly maintained, it can also be recycled for many times. Compared with the one-time pouring equipment, the material procurement cost is greatly reduced and the waste of resources is reduced; 5. The tension bolts around the baffle are reinforced and the limit block is designed to prevent it from falling off, which fully guarantees the safety of the entire concrete transportation process. The tension bolts tighten the baffle to prevent it from collapsing and deforming due to the impact of concrete; the limit block locks the connection structure of the blanking plate to prevent the fixed block from accidentally slipping out of the slot and causing the risk of equipment disintegration, thus reducing the probability of accidents. 6. The connection device array arrangement of the present invention can improve the stability of the blanking plate during the blanking process, and avoid deformation of the blanking plate due to uneven force, thereby causing a gap between the blanking plate and the baffle plate and causing concrete leakage.

[0016] In order to clearly illustrate the technical features of the present invention, the present invention is described in detail below through specific implementation methods and in conjunction with the accompanying drawings.

[0017] Example 1 See also Figures 1 to 5A detachable tool for efficient transportation of secondary structure concrete, comprising a base plate 1, a baffle 2, a blanking plate 4 and a corrugated pipe 6, wherein the baffle 2 is arranged on the base plate 1, the blanking plate 4 is connected to the base plate 1 through a connecting device 5, a reserved hole 41 is arranged on the blanking plate 4, the corrugated pipe 6 is connected to the reserved hole 41, a counterweight area 102 and a discharge area 101 are arranged on the base plate 1, the baffle 2 is arranged around the base plate 1 and the blanking plate 4, and a reinforcement device 21 is arranged around the baffle 2.

[0018] like Figure 1 and Figure 5 As shown, the connecting device 5 includes a slot 51 and a fixed block 52, the slot 51 is arranged at the bottom of the base plate 1, the fixed block 52 is arranged at the bottom of the blanking plate 4, the fixed block 52 is slidably connected in the slot 51, and an anti-falling device is arranged at one end of the baffle 2 close to the blanking plate 4.

[0019] like Figure 5 As shown, the connecting devices 5 are arranged in an array.

[0020] like Figure 2 and Figure 3 As shown, the anti-falling device is a limit block 53, and the limit block 53 is rotatably connected to the baffle 2.

[0021] like Figure 3 As shown, a blocking plate 3 is provided between the counterweight area 102 and the discharge area 101 to prevent concrete from contaminating the counterweight area 102 .

[0022] like Figures 1 to 5 As shown, the reinforcing device 21 is a tension bolt, and the tension bolt is connected to the baffle 2.

[0023] A method for efficiently conveying secondary structure concrete, using a detachable tool for efficiently conveying secondary structure concrete to convey the secondary structure concrete, specifically comprising the following steps: Step 1: Determine the diameter of the reserved hole 41 according to the concrete pumping volume, select the blanking plate 4, connect the blanking plate 4 with the bottom plate 1, and connect the corrugated pipe 6 with the reserved hole 41; Step 2: Place a detachable tool for efficient secondary structure concrete transportation on the upper outer wall or opening area, place a counterweight block in the counterweight area 102, and then use tension bolts and wooden squares to install the detachable tool for efficient secondary structure concrete transportation on the main structure of the building; if a detachable tool for efficient secondary structure concrete transportation is placed in the outer wall area, the counterweight area 102 is stabilized by gravity toward the room, the blanking plate 4 is cantilevered toward the outside, and the corrugated pipe 6 falls through the outer wall space to the lower construction pouring part; if a detachable tool for efficient secondary structure concrete transportation is placed in the reserved opening area, it falls directly above the opening and is stabilized by the counterweight device, wherein the corrugated pipe 6 is aligned with the opening and falls to the lower construction pouring part Step 3: The concrete truck unloads the concrete to the discharge area 101 through the bucket truck, and then pushes the concrete from the discharge area 101 to the discharge plate 4 and enters the reserved hole 41, and the concrete flows through the corrugated pipe 6 to cast the secondary structure; Step 4: After pouring is completed, remove the counterweight and clean the bottom plate 1 and the blanking plate 4 to prevent the concrete from solidifying.

[0024] Principle and operation process The base plate 1 serves as the basic bearing component, bearing the weight of the entire tool and concrete; the baffle 2 is arranged around it to form a closed and high-strength enclosure structure. As a connecting piece to the building frame, the tension bolts apply inward tension around the baffle 2 to maintain the stability of the tool shape and prevent the baffle 2 from deforming or collapsing. The connecting device 5 uses a slot 51 and a fixing block 52 to tightly splice the blanking plate 4 with the base plate 1. The connecting device 5 is arranged in an array, and the multi-point connection disperses the force. The limit block 53 serves as an anti-falling device, which rotates and clamps the fixing block 52 to prevent the fixing block 52 from sliding out of the slot 51 under construction vibration and concrete impact, further strengthening the overall structural continuity.

[0025] When the tool is placed on an exterior wall or in an opening, the force on the tool is balanced by the gravity distribution of the counterweight block in the counterweight area 102. On the exterior wall, the counterweight area 102 uses the gravity sinking trend toward the interior to stabilize the tool body, preventing it from unbalanced and tipping over due to the overhanging blanking plate 4 and corrugated pipe 6; when the tool is above the opening, the counterweight block directly presses down, and with the tool's own structure, the corrugated pipe 6 is accurately aligned with the opening, ensuring that the concrete falls vertically to the pouring site, achieving stable transportation.

[0026] The appropriate hole diameter can match the concrete flow rate to prevent blockage or uneven flow rate. After the concrete is unloaded from the bucket truck to the discharge area 101, it flows to the lower material plate 4 with the help of a manual shovel. The concrete flows into the corrugated pipe 6, guiding the concrete to overcome the obstacles of the building structure and reach the secondary structure construction position. A blocking plate 3 is arranged between the counterweight area 102 and the discharge area 101 to block the path of concrete that may flow to the counterweight area 102. During the discharge and pushing process, even if the concrete has a tendency to overflow due to flow inertia or operational errors, the blocking plate 3 can directly block it to prevent the concrete from contaminating the counterweight block, keep the counterweight area 102 clean, ensure the tool counterweight is accurate, and continuously and stably play the role of stabilizing the tool posture, thereby improving the service life and reliability of the equipment.

[0027] When using, first determine the number of tools required based on the conditions of the construction site and the layout of the secondary structure, and rationally plan spare parts to prevent sudden damage during construction and replace them in time. Construction personnel survey the upper outer wall of the building and the surrounding environment of the reserved opening in advance, measure the space dimensions of the outer wall, and check whether there are protrusions or obstacles that affect the passage of the corrugated pipe 6; check the size and verticality of the opening to ensure that the tool can be accurately positioned. When selecting the placement point on the outer wall, consider the structural strength of the building's facade, and give priority to the corresponding position of the load-bearing wall; for the opening area, clean up the debris and dust around the opening, and make fine adjustments to the flatness of the placement platform to ensure that the tool is seated stably.

[0028] After the tool is in place, when it is set on the exterior wall, it is close to the exterior wall of the building. Wood squares are nailed into the corresponding position of the baffle 2, and the tool is further fixed to the wall with the tension bolts. The length of the wood square is selected according to the thickness of the exterior wall, generally 15-30 cm, and the nailing depth is not less than two-thirds of the length of the wood square. When the tool is set at the opening, a small lifting equipment is used to lift the tool above the opening, and it is slowly lowered so that the base of the tool is completely seated on the solid part around the opening. Wood squares are nailed around the baffle 2 and reinforced with tension bolts. After the concrete transport vehicle arrives, it uses a bucket truck to add concrete to the discharge area 101, and uses tools to push the concrete to the reserved hole 41. After the concrete flows into the corrugated pipe 6, the construction workers at the lower level can adjust the position of the corrugated pipe 6 to cast the designated area.

[0029] After pouring is completed, use a high-pressure water gun to rinse the bottom plate 1 and the discharge plate 4 before the concrete dries up, focusing on the accumulation of residual concrete and the gaps. Then loosen the connection between the bellows 6 and the discharge plate 4, remove the bellows 6, unscrew the tension bolts, remove the baffle 2, and sort and stack them; remove the blocking plate 3, clean the surrounding concrete; take out the counterweight block, and the recovery device can be reused.

[0030] Although the above describes the specific implementation mode of the present invention in conjunction with the accompanying drawings, it is not intended to limit the scope of protection of the present invention. Based on the technical solution of the present invention, various modifications or variations that can be made by those skilled in the art without creative work are still within the scope of protection of the present invention.
