In the present application, the up-and-down movement of the adsorbing and smearing body can comprehensively smear the inner wall of the planting cavity of the building prefabricated part body with the maintenance agent, so that the planting cavity is sprayed with the maintenance agent during the stacking of the building prefabricated part body, thereby solving the problem that the existing stacking device cannot conveniently spray the planting cavity of the building prefabricated part body with the maintenance agent after the stacking of the building prefabricated part body, which leads to the fact that the inner wall position of the concrete prefabricated part cannot be maintained, and further leads to the fact that the concrete prefabricated part is prone to cracking during the maintenance period.

Description

Technical Field

[0001] This invention relates to the field of prefabricated building component stacking technology, and specifically to a stacking device for prefabricated building components. Background Technology

[0002] River ecological slope protection is a new type of prefabricated ecological building component used for the treatment and protection of slopes in water conservancy projects, such as waterfront areas, rivers, dams, reservoirs, and water storage ponds, while taking environmental factors into account. Prefabricated building components, also known as precast parts, refer to building components with specific specifications and dimensions that are processed and produced in factories or on-site using standardized and mechanized methods. These components can be combined and installed according to design requirements and are widely used in construction, transportation, water conservancy, and other fields. Common prefabricated building components include precast reinforced concrete columns, precast steel structure columns, and precast floor slabs, among which the prefabricated building components used in river ecological slope protection are precast concrete components.

[0003] The precast concrete component has a planting cavity for placing soil and planting greenery. It also has drainage openings on the side walls and bottom. When in use, the precast concrete components can be arranged together to protect the riverbank, prevent soil erosion, restore and improve the damaged natural ecosystem, and enhance the ecological function and landscape effect of the river. Since the precast concrete components are building components made in the factory with concrete as the basic material, they need to be stacked after demolding and require subsequent curing, which can be done by spraying curing agents, etc.

[0004] Existing palletizing equipment makes it difficult to apply curing agent to the planting cavity of precast concrete components after they are stacked. This results in the inability to cure the inner wall of the planting cavity, which can easily lead to cracking of the precast concrete components during the curing period.

[0005] Therefore, it is necessary to provide a new technical solution to overcome the above-mentioned defects. Summary of the Invention

[0006] The purpose of this invention is to provide a stacking device for prefabricated building components that can effectively solve the above-mentioned technical problems.

[0007] To achieve the objectives of this invention, the following technical solution is adopted:

[0008] A stacking device for precast building components includes: a robotic arm and a gripping mechanism installed at the movable end of the robotic arm; the gripping mechanism includes: a pick-and-place assembly for picking up and placing precast building components, and a curing assembly for curing the precast building components with a curing agent; the curing assembly includes: a spraying unit for uniformly spraying the curing agent, and a control unit for controlling the amount of curing agent sprayed; the spraying unit includes: a mounting box, a liquid storage tank fixedly installed on the top of the mounting box, a first connecting pipe inserted into the bottom of the liquid storage tank and the side wall of the mounting box, a second connecting pipe sleeved on the outer edge of the first connecting pipe, an annular pipe inserted into the bottom end of the second connecting pipe, a nozzle inserted into the outer edge of the annular pipe, and a spreading unit for uniformly spreading the sprayed curing agent; the control unit includes: a vertical rod penetrating and installed inside the first and second connecting pipes, a sealing plug fixedly sleeved on the outer edge of the vertical rod, and a horizontal rod fixedly installed at the bottom end of the vertical rod.

[0010] Furthermore, the maintenance assembly also includes: a sleeve fitted on the outer edge of the rotating shaft, a circular plate rotatably mounted on the outer edge of the sleeve, a stirring blade fixedly mounted on the outer side of the sleeve, a groove formed on the inner wall of the sleeve, and a slide bar slidably mounted in the inner cavity of the groove.

[0011] Furthermore: the first connecting pipe consists of a large-diameter branch pipe 1 and two small-diameter branch pipes 2, and the inner cavities of branch pipe 1 and branch pipe 2 are interconnected, and the diameter of the sealing plug is larger than the diameter of branch pipe 2.

[0012] Furthermore, the pick-and-place assembly includes: a limiting opening at the bottom of the mounting box, a clamping plate installed through the inner cavity of the limiting opening, a plug-in rod fixedly installed on the side wall of the clamping plate, a linkage unit that drives the clamping plate to move, and a limiting unit that limits the movement of the clamping plate.

[0013] Furthermore, the linkage unit includes: a thread formed on the outer edge of the rotating shaft, a threaded plate threaded on the outer edge of the rotating shaft, a connecting rope fixedly installed between the clamping plate and the threaded plate, a U-shaped plate symmetrically fixedly installed at the bottom of the mounting box, and a pulley movably installed in the inner cavity of the U-shaped plate.

[0014] Furthermore, the limiting unit includes: a fixed plate fixedly installed on the inner wall of the mounting box; a limiting rod installed through the side wall of the clamping plate; the two ends of the limiting rod being fixedly installed on the side wall of the fixed plate and the inner wall of the mounting box, respectively; and a connecting spring sleeved on the outer edge of the limiting rod; the two ends of the connecting spring being fixedly installed on the side wall of the fixed plate and the inner wall of the mounting box, respectively.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] This invention discloses a stacking device for precast building components. By moving an adsorbent coating body up and down, a curing agent can be applied comprehensively to the inner wall of the planting cavity of the precast building component. This allows the planting cavity to be sprayed with curing agent during the stacking process, thus solving the problem that existing stacking devices are not convenient for spraying curing agent onto the planting cavity of the precast building component after stacking, which leads to the inability to cure the inner wall of the concrete precast component and makes it easy for the concrete precast component to crack during the curing period.

[0033] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are some embodiments of the present invention, but not all embodiments.

The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only.

[0035] like Figures 1 to 6As shown, the present invention provides a stacking device for precast building components, comprising: a robotic arm 1, and a gripping mechanism 2 installed at the movable end of the robotic arm 1; the gripping mechanism 2 includes: a gripping and placing component 21 for picking up and placing precast building components, and a curing component 22 for curing precast building components with a curing agent; the curing component 22 includes: a spraying unit 221 for uniformly spraying the curing agent, and a control unit 222 for controlling the amount of curing agent sprayed.

[0036] Precast concrete riverbank ecological revetment is a type of revetment that uses precast concrete blocks as a base with pre-drilled holes for plant growth. In this application, the precast building component 3 has a circular planting cavity at the center of its top, which can hold soil for planting greenery. Drainage openings are provided on the side walls and bottom. Figure 6 As shown, using precast concrete riverbank protection as the base material has a short production cycle and is economical. When in use, the precast concrete components can be arranged together to protect the riverbank, prevent soil erosion, restore and improve the damaged natural ecosystem, and enhance the ecological function and landscape effect of the river.

[0037] After the precast building component 3 is demolded, the precast building component can be picked up and put down by the pick-up and put-down component 21, and the precast building component can be cured with curing agent by the curing component 22.

[0038] The spraying unit 221 includes: a mounting box 2211, a liquid storage tank 2212 fixedly installed on the top of the mounting box 2211, a first connecting pipe 2213 inserted into the bottom of the liquid storage tank 2212 and the side wall of the mounting box 2211, a second connecting pipe 2214 sleeved on the outer edge of the first connecting pipe 2213, an annular pipe 2215 inserted into the bottom end of the second connecting pipe 2214, a nozzle 2216 inserted into the outer edge of the annular pipe 2215, and a coating unit 2217 for evenly applying the sprayed curing agent. The curing agent inside the liquid storage tank 2212 flows into the second connecting pipe 2214 through the first connecting pipe 2213, flows into the inner cavity of the annular pipe 2215 through the second connecting pipe 2214, and is discharged through several nozzles 2216. Since the nozzles 2216 are evenly distributed in a ring on the outer edge of the annular pipe 2215, the curing agent is sprayed evenly.

[0039] The applicator unit 2217 includes: a rotating shaft 22171 rotatably mounted on the side wall of the mounting box 2211, a motor 22172 that drives the rotating shaft 22171 to rotate, a movable tube 22173 sleeved on the outer edge of the rotating shaft 22171, a fixed rod 22174 fixedly mounted on the bottom end of the movable tube 22173, an adsorption applicator 22175 fixedly sleeved on both ends of the fixed rod 22174, a limiting groove formed in the inner wall of the movable tube 22173, and a limiting strip 22176 slidably mounted in the inner cavity of the limiting groove.

[0040] When the motor 22172 rotates forward, the rotating shaft 22171 drives the limiting strip 22176 to rotate, which in turn drives the movable tube 22173 to rotate. The movable tube 22173 then drives the fixed rod 22174 to rotate, which in turn drives the adsorption applicator 22175 to rotate. The rotation of the adsorption applicator 22175 allows the curing agent to be evenly applied to the inner wall of the planting cavity of the precast building component 3. Simultaneously, the threaded plate 2131 drives the two second connecting pipes 2214 to move downwards. These two second connecting pipes 2214 together drive the annular tube 2215 to move downwards, which in turn drives several nozzles 2216 to move downwards, thus moving the nozzles 2216 into the planting cavity. Internally, the annular tube 2215 drives the movable tube 22173 downward, which in turn drives the fixed rod 22174 downward, which in turn drives the adsorption coating body 22175 downward. This downward movement of the adsorption coating body 22175 allows for comprehensive application of curing agent to the inner wall of the planting cavity. This enables the precast building component 3 to be cured by spraying curing agent onto the planting cavity during the stacking process. This solves the problem of existing stacking equipment where it is inconvenient to apply curing agent to the planting cavity of the precast building component 3 after stacking, preventing the inner wall of the concrete precast component from being cured and thus easily leading to cracking during the curing period.

[0041] After the precast building component 3 is clamped, the robotic arm 1 can stack the precast building component 3. After the precast building component 3 is placed in the designated position, the motor 22172 is started to rotate in the reverse direction, which drives the rotating shaft 22171 to rotate in the reverse direction. The rotating shaft 22171 drives the threaded plate 2131 to move upward, which in turn drives the adsorption coating body 22175 to move upward. By moving the adsorption coating body 22175 upward, the curing agent can be applied again to the inner wall of the planting cavity at the top of the precast building component 3. This allows for a second coating of the planting cavity, making the curing agent application more comprehensive and thorough, improving the curing effect of the precast building component 3, and preventing cracking of the precast building component 3 during the curing period.

[0042] It should be noted that, because the nozzles 2216 are evenly distributed in a ring on the outer edge of the annular tube 2215, the curing agent flows evenly into the adsorption applicator 22175. Since the adsorption applicator 22175 is made of sponge material, it can absorb the curing agent. Furthermore, the annular design of the adsorption applicator 22175 allows it to rotate, ensuring that its entire top passes over the nozzles 2216, thus allowing it to fully absorb the curing agent and fill its entire interior. Simultaneously, the rotation of the adsorption applicator 22175 applies the curing agent to the inner wall of the implantation cavity. Due to the annular design of the adsorption applicator 22175, its outer side makes full contact with the inner wall of the implantation cavity, thereby improving the uniformity of the curing agent application.

[0043] It is worth noting that the length of the threaded area on the outer edge of the rotating shaft 22171 is the same as the depth of the implantation cavity and the clamping distance of the clamping plate 211. Therefore, when the threaded plate 2131 moves to the lowest point of the threaded area, the adsorbent coating body 22175 moves from the top to the bottom of the implantation cavity, and at the same time, the two clamping plates 211 just complete the clamping of the precast building component body 3.

[0044] The adsorbent applicator 22175 can absorb the maintenance agent. The adsorbent applicator 22175 is ring-shaped and can rotate. By rotating, its entire top passes over the nozzle 2216, ensuring full absorption of the maintenance agent and filling the entire interior of the adsorbent applicator 22175. Simultaneously, the adsorbent applicator 22175 applies the maintenance agent to the inner wall of the implantation cavity. Due to its ring-shaped design, the outer side of the adsorbent applicator 22175 makes full contact with the inner wall of the implantation cavity, thus improving the uniformity of the maintenance agent application.

[0045] The absorbent coating material 22175 can be made of sponge.

[0046] The control unit 222 includes: a vertical rod 2221 that is installed through the inner cavity of the first connecting pipe 2213 and the second connecting pipe 2214; a sealing plug 2222 that is fixedly sleeved on the outer edge of the vertical rod 2221; and a horizontal rod that is fixedly installed at the bottom end of the vertical rod 2221. The first connecting pipe 2213 is composed of a large-diameter branch pipe 1 and two small-diameter branch pipes 2, and the inner cavities of the branch pipe 1 and the branch pipe 2 are interconnected. The diameter of the sealing plug 2222 is larger than the diameter of the branch pipe 2.

[0047] When motor 22172 rotates forward, the threaded plate 2131 drives the two second connecting pipes 2214 to move downward. The second connecting pipes 2214 drive the adjacent horizontal bar to move downward. The horizontal bar drives the vertical bar 2221 to move downward. The vertical bar 2221 drives the sealing plug 2222 to move downward inside the first connecting pipe 2213. Since the first connecting pipe 2213 consists of a large-diameter branch pipe 1 and two small-diameter branch pipes 2, and the inner cavities of branch pipe 1 and branch pipe 2 are interconnected, and the diameter of the sealing plug 2222 is larger than the diameter of branch pipe 2, when the threaded plate 2131 is at the highest point of the threaded area, the sealing plug 2222 is located at the top of the inner cavity of branch pipe 1. At this time, the sealing plug 2222 can seal the branch pipe 2 located at the top. At this time, the preservative inside the liquid storage tank 2212 cannot pass through the first connecting pipe 2213. The fluid flows into the second connecting pipe 2214 through the connecting pipe 2213. When the sealing plug 2222 moves downward, it no longer seals the branch pipe 2222 at the top of the first connecting pipe 2213. At this time, the curing agent inside the storage tank 2212 flows into the second connecting pipe 2214 through the first connecting pipe 2213, then into the inner cavity of the annular pipe 2215 through the second connecting pipe 2214, and flows onto the adsorption coating body 22175 through several nozzles 2216. Since the adsorption coating body 22175 is made of sponge material, it can absorb the curing agent. When the threaded plate 2131 moves to the lowest point of the threaded area, the sealing plug 2222 moves to the lowest point of the branch pipe 1, thus sealing the branch pipe 2213 at the bottom of the first connecting pipe 2213. At this time, the curing agent cannot enter the inner cavity of the annular pipe 2215.

[0048] After the precast building component body 3 is clamped, the robotic arm 1 can stack the precast building component body 3. After the precast building component body 3 is placed in the designated position, the motor 22172 is started to rotate in the reverse direction, which drives the rotating shaft 22171 to rotate in the reverse direction. The rotating shaft 22171 drives the threaded plate 2131 to move upward, which in turn drives the sealing plug 2222 to move upward. When the sealing plug 2222 moves upward, it does not have a sealing effect on the branch pipe 2 at the bottom of the first connecting pipe 2213. At this time, the curing agent continues to... The material continues to flow downwards and onto the absorbent coating body 22175. When the threaded plate 2131 moves to the top, the sealing plug 2222 again seals the branch pipe 2 at the top of the first connecting pipe 2213. At this time, the curing agent cannot flow out. Thus, by moving the sealing plug 2222 up and down, the discharge of the curing agent can be controlled, thereby controlling the amount of curing agent discharged. This avoids the problem of insufficient discharge affecting the spraying effect, and also avoids the problem of excessive discharge leading to waste of curing agent, thus saving production costs.

[0049] It is important to note that the length of the threaded area on the outer edge of the rotating shaft 22171 is the same as the length of the first branch pipe of the first connecting pipe 2213. Therefore, when the threaded plate 2131 moves to the lowest point of the threaded area, the sealing plug 2222 moves to the lowest point of the first branch pipe, at which point the second branch pipe located at the bottom can be sealed. When the sealing plug 2222 moves to the highest point of the first branch pipe, the second branch pipe located at the top can be sealed.

[0050] The maintenance component 22 also includes: a sleeve fitted on the outer edge of the rotating shaft 22171, a circular plate 2219 rotatably installed on the outer edge of the sleeve, a stirring blade 2218 fixedly installed on the outer side of the sleeve, a groove formed on the inner wall of the sleeve, and a slide bar slidably installed in the inner cavity of the groove.

[0051] When the motor 22172 rotates forward, it drives the slide bar to rotate via the rotating shaft 22171, which in turn drives the sleeve to rotate. The sleeve then drives the stirring blade 2218 to rotate, and the vertical rod 2221 drives the circular plate 2219 to move downward. The circular plate 2219 then drives the sleeve to move downward, which in turn drives the stirring blade 2218 to move downward. This allows the stirring blade 2218 to move downward while rotating. The rotation of the stirring blade 2218 can stir the curing agent in the inner cavity of the storage tank 2212, preventing the curing agent from settling. The downward movement of the stirring blade 2218 expands the stirring range, improves the uniformity of the curing agent, and thus improves the spraying effect of the curing agent.

[0052] After the precast building component body 3 is clamped, the precast building component body 3 can be stacked by the robotic arm 1. After the precast building component body 3 is placed in the designated position, the motor 22172 is started to rotate in the reverse direction, which drives the rotating shaft 22171 to rotate in the reverse direction. The rotating shaft 22171 drives the threaded plate 2131 to move upward, which in turn drives the stirring blade 2218 to move upward. The upward movement of the stirring blade 2218 can stir the curing agent from bottom to top, which further improves the uniformity of the curing agent and thus improves the spraying effect of the curing agent.

[0053] By moving up and down and rotating the stirring blades 2218, the curing agent in the inner cavity of the storage tank 2212 can be fully stirred to prevent the curing agent from settling. Compared with the traditional fixed stirring, the stirring range is expanded, so the curing agent can be better turned over and mixed, making the curing agent more uniform during the stirring process.

[0054] The pick-and-place assembly 21 includes: a limiting opening at the bottom of the mounting box 2211, a clamping plate 211 that penetrates and is installed inside the limiting opening, a plug-in rod 212 that is fixedly installed on the side wall of the clamping plate 211, a linkage unit 213 that drives the clamping plate 211 to move, and a limiting unit 214 that limits the movement of the clamping plate 211. The linkage unit 213 includes: a thread on the outer edge of the rotating shaft 22171, a threaded plate 2131 that is threaded on the outer edge of the rotating shaft 22171, a connecting rope 2132 that is fixedly installed between the clamping plate 211 and the threaded plate 2131, a U-shaped plate 2133 that is symmetrically fixedly installed at the bottom of the mounting box 2211, and a pulley 2134 that is movably installed inside the cavity of the U-shaped plate 2133.

[0055] By activating the robotic arm 1, the gripping mechanism 2 is moved to the top of the precast building component body 3. At this time, the two clamping plates 211 are located on both sides of the precast building component body 3, and the two plug-in rods 212 are aligned with the drainage openings on both sides of the precast building component body 3. Meanwhile, the adsorption applicator 22175 is located directly above the planting cavity at the top of the precast building component body 3, and the outer diameter of the adsorption applicator 22175 matches the inner cavity of the planting cavity.

[0056] When the motor 22172 rotates forward, the threaded plate 2131 is threaded onto the outer edge of the rotating shaft 22171. The rotating shaft 22171 drives the threaded plate 2131 to move downward, which in turn pulls down the two connecting ropes 2132. The two connecting ropes 2132 then move the adjacent clamping plates 211 closer together, which in turn move the adjacent plug-in rods 212 closer together. When the two clamping plates 211 are tightly fitted to both sides of the precast building component body 3, the two plug-in rods 212 are inserted into the adjacent drainage openings, thus clamping and fixing the precast building component body 3. The two clamping plates 211 clamp and fix both sides of the precast building component body 3, and the two plug-in rods 212 are inserted into the inner cavity of the adjacent drainage openings, preventing the precast building component body 3 from falling off during movement and improving the stability during stacking.

[0057] After the precast building component body 3 is clamped, the adsorption coating body 22175 moves into the planting cavity of the precast building component body 3. The adsorption coating body 22175 and the fixing rod 22174 can support the inner wall of the planting cavity. In conjunction with the clamping plate 211 and the outer clamping of the insertion rod 212, the stability of clamping the precast building component body 3 is further improved.

[0058] The limiting unit 214 includes: a fixing plate 2141 fixedly installed on the inner wall of the mounting box 2211; a limiting rod 2142 through-mounted on the side wall of the clamping plate 211, with both ends of the limiting rod 2142 fixedly installed on the side wall of the fixing plate 2141 and the inner wall of the mounting box 2211 respectively; and a connecting spring 2143 sleeved on the outer edge of the limiting rod 2142, with both ends of the connecting spring 2143 fixedly installed on the side wall of the fixing plate 2141 and the inner wall of the mounting box 2211 respectively. The limiting rod 2142 guides the movement of the clamping plate 211. During the movement of the clamping plate 211, the linkage spring 2143 deforms. When the two clamping plates 211 clamp the precast building component 3, the linkage spring 2143 is compressed. When the two clamping plates 211 release the precast building component 3, the adjacent clamping plate 211 is reset by the elastic force of the linkage spring 2143.
