Description

Technical Field

[0001] The invention relates to the field of production and manufacturing of prefabricated concrete parts, and in particular to a corrosion-resistant treatment system for prefabricated reinforced concrete. Background Art

[0002] Precast reinforced concrete, also known as precast reinforced concrete parts, are concrete structural components, including precast reinforced concrete column foundations, precast steel structure steel column foundations, street light billboard column reinforced concrete foundations, and precast floor slabs. After the precast reinforced concrete parts are processed and manufactured in a mechanized manner in the factory, they can be directly transported to the construction site for installation. Compared with the traditional practice of cement mixing and manufacturing at the construction site, they have the advantages of higher safety factor and faster construction progress. Therefore, precast reinforced concrete parts are now widely used in construction, transportation, water conservancy and other fields, playing an important role in the national economy.

[0003] Existing prefabricated reinforced concrete mostly uses a steel mesh made of several steel bars as an additional structure inside the concrete. The steel mesh forms good bonding and anchoring properties with the concrete through the mesh structure, which can evenly diffuse the load, significantly improve the strength and stability of the reinforced concrete prefabricated structure, reduce the occurrence of cracks, and thus improve the durability and service life of the prefabricated parts. At the same time, in order to further improve the service life of reinforced concrete prefabricated parts, before pouring concrete, the steel mesh will be immersed in an anti-corrosion liquid for anti-corrosion treatment. Common prefabricated reinforced concrete corrosion-resistant treatment systems include a large area of ​​anti-corrosion liquid pool and a carrying mechanism for carrying the steel mesh. The carrying mechanism moves the steel mesh to the anti-corrosion liquid pool for full immersion and then removes it to dry or bake, thereby completing the anti-corrosion treatment of the steel bars.

[0004] The anti-corrosion liquid has a certain degree of adhesion. During the period when the steel mesh is taken out of the anti-corrosion liquid pool to dry, the anti-corrosion liquid will drip along the steel bars. Due to the large overall structure of the steel mesh, the dripping anti-corrosion liquid will scatter everywhere, which not only destroys the working environment, but also causes a waste of anti-corrosion liquid and increases the production cost of precast reinforced concrete. Summary of the invention

[0005] The present invention aims to provide a prefabricated reinforced concrete corrosion-resistant treatment system to solve the problem of excessive waste of anti-corrosion liquid in the existing steel bar anti-corrosion treatment and reduce the production cost of prefabricated reinforced concrete.

[0006] To achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a prefabricated reinforced concrete corrosion-resistant treatment system, including an anti-corrosion liquid tank and a mobile unit; also including a recovery tank, a one-way valve is provided between the recovery tank and the anti-corrosion liquid tank for connection, the bottom surface of the recovery tank is an inclined surface, and the bottom of the inclined surface is close to the one-way valve; the mobile unit includes a power slide rail, a support slide rail and a plurality of connecting components arranged between the support slide rail and the power slide rail, the connecting components all include a beam rotatably and slidably connected to the support slide rail and a plurality of steel chisels connected to the beam; the steel chisels all include a lifting section and a connecting section that are coaxially rotatably connected, the lifting section is threadedly connected to the beam, the connecting section is connected to a woven steel mesh bar, and after the connection, the bottom of the lifting section is in contact with the top of the connecting section.

[0007] The beneficial effects of this scheme are: 1. The recovery pool is set beside the anti-corrosion liquid pool, and the anti-corrosion liquid dripping on the steel mesh during the drying period is recycled through a one-way valve, reducing the waste of anti-corrosion liquid, solving the problem of excessive waste of anti-corrosion liquid in the existing steel bar anti-corrosion treatment, and reducing the production cost of prefabricated reinforced concrete.

[0008] 2. When the anti-corrosion liquid is dipped and the steel mesh is moved to the top of the recovery pool to dry, the lifting section rotates due to the mutual restraint of the woven steel mesh between the connecting sections. The lifting section starts to rotate, but the connecting sections are restricted by the steel mesh. Only at the beginning, the rotational potential energy generated by inertia causes a slight relative rotation between the connecting section and the clamp, thereby avoiding the problem that the adhesion of the anti-corrosion liquid itself will further increase the connection strength between the clamp and the steel bar after drying, and the subsequent pouring of concrete will cause excessive friction and jamming when the clamp is pushed downward from the connecting section, causing damage to the connecting components.

[0009] 3. The connecting components include a crossbeam that is rotatably and slidably connected to the supporting slide rail and a number of steel bar connected to the crossbeam. According to the weaving requirements of different steel meshes, the steel bar that is not needed for hanging the steel mesh can be customized to rotate and then the connecting section can be inserted into the hanging hole to hang the group of steel bar on the adjacent crossbeam, thereby avoiding the steel bar that is not connected to the steel mesh from entering the antiseptic liquid pool together, causing waste of antiseptic liquid.

[0010] Preferably, a long liquid collection trough is provided at the bottom end of the inclined surface, the liquid collection trough is located at one end of the recovery tank close to the preservative liquid tank, and the one-way valve is located between the liquid collection trough and the preservative liquid tank, and a filter plate is detachably connected to the liquid collection trough.

[0011] Preferably, the thickness of the transition plate is greater than or equal to 1 cm, and the bottom surface of the transition plate is flush with the lowest point of the inclined surface.

[0012] The beneficial effect of this solution is as follows: since the filter plate has a certain height, a stacking angle less than 90° is formed between the filter plate and the bottom of the slope. After impurities and lumps flow down with the flowing preservative liquid, they will first accumulate in the stacking angle for the first filtration, and then the liquid preservative will overflow upward and then pass through the filter plate into the liquid accumulation tank, thereby reducing the need to replace the filter plate and further reducing the production cost of precast reinforced concrete.

[0013] Preferably, the interior of the crossbeam is a cavity, in which several nuts are rotatably connected, and the outer peripheries of the nuts are provided with chain teeth. An annular chain is provided in the cavity, which meshes with all the nuts. The annular chain is connected to a driving sprocket, and the driving sprocket is connected to a motor as a driving mechanism, and the lifting sections are respectively threadedly connected to the nuts.

[0014] Preferably, the crossbeams are provided with hanging holes, the hanging holes and the threaded holes are staggered with each other, and the connecting sections can be inserted into the hanging holes.

[0015] Preferably, a power chain is provided in the power slide rail, a slider is provided on the support slide rail, the crossbeam is rotatably and slidably connected to the slider, and a connecting column is provided between the power chain and the slide rail for connection.

[0016] Preferably, a cleaning member is connected to the power slide rail, and the cleaning member includes a cleaning block and a plurality of supporting legs fixed on the cleaning block, and the supporting legs are connected to the power chain. After the connection, the top surface of the cleaning block is in contact with the top surface of the slide groove inside the power slide rail.

[0017] Preferably, the cleaning block includes a top plate, a bottom plate and two side plates, the supporting legs are fixed on the bottom plate, the top plate is vertically slidably connected to the bottom plate by setting a plurality of telescopic rods, and compression springs are vertically provided inside the telescopic rods; a baffle is welded and fixed on both sides of the bottom plate, and the width of the baffle is the same as the width of the inner wall of the groove of the power slide rail.

[0018] The beneficial effects of this solution are: 1. The additional baffle can not only receive the sludge scraped off by the top plate and the side plates to prevent the sludge from falling downwards, but also increase the length of the entire cleaning block, thereby further improving the cleaning block's effect on improving the stability of the power chain when it moves.

[0019] 2. Under the action of the compression spring inside the telescopic rod, the top plate will be continuously pushed upward to compensate for the wear on the top surface of the top plate, so that the top plate is always in contact with the power slide rail to ensure the cleaning effect.

[0020] Preferably, the bottom of the lifting section and the top of the connecting section are connected by setting a combined bearing, and guide bars are symmetrically arranged on the combined bearing. The guide bars are all in a straight line state and can rotate relative to the lifting section; symmetrical guide grooves are opened on both sides of the hanging hole, and the guide bars can enter the guide grooves.

[0021] The beneficial effect of this scheme is: all lifting sections are driven by the lifting chain to move closer to the hanging holes on the adjacent beams. If the group of lifting sections can synchronously drive the guide strips on the combined bearings to fit into the guide grooves on both sides of the hanging holes after rotation, it indicates that the lifting sections in the group of steel chisels have not been deformed and the standard degree of the woven steel mesh can be guaranteed; if some or all of the lifting sections cannot drive the guide strips on the combined bearings to enter the guide grooves smoothly, it indicates that the lifting sections have been bent and deformed and need to be replaced to ensure the standard degree of the woven steel mesh.

[0028] The following is further described in detail through specific implementation methods:

[0029] The figure marks in the drawings of the specification include: antiseptic liquid pool 1, recovery pool 2, inclined surface 21, liquid accumulation tank 22, protrusion 221, filter plate 23, one-way valve 24, power slide rail 3, power chain 31, support slide rail 4, slider 41, connecting column 42, crossbeam 5, transverse slide rail 50, rotating rod 501, nut 51, hanging hole 52, guide groove 521, steel drill 6, lifting section 61, connecting section 62, bearing 63, combined bearing 630, guide strip 631, cleaning block 7, support leg 70, top plate 71, bottom plate 72, side plate 73, baffle 74, telescopic rod 75.

[0030] Example 1

[0031] Embodiment 1 is basically as attached Figure 1-3 As shown, Figure 1The prefabricated reinforced concrete corrosion-resistant treatment system shown is used for immersing the steel mesh that is about to be poured with concrete in an anti-corrosion liquid; it includes an anti-corrosion liquid pool 1, a moving unit and a recovery pool 2, the moving unit is located above the anti-corrosion liquid pool 1 and the recovery pool 2, and is used to hang and drive the steel mesh to move; the anti-corrosion liquid pool 1 is filled with anti-corrosion liquid that can immerse the steel mesh as a whole, and the recovery pool 2 is arranged on the side of the anti-corrosion liquid pool 1, and is used to recycle the anti-corrosion liquid dripping on the steel mesh during drying, thereby reducing the waste of anti-corrosion liquid.

[0032] Combination Figure 1 , Figure 2 As shown, the recovery pool 2 and the antiseptic liquid pool 1 are both rectangular parallelepipeds, and the right end of the recovery pool 2 is spliced ​​with the left end of the antiseptic liquid pool 1. In this embodiment, the recovery pool 2 and the antiseptic liquid pool 1 are both made of concrete. The bottom surface of the recovery pool 2 is set as an inclined surface 21, and a long liquid accumulation groove 22 is provided at the bottom end of the inclined surface 21. The liquid accumulation groove 22 is close to the end where the recovery pool 2 is connected to the antiseptic liquid pool 1. A filter plate 23 is detachably connected to the liquid accumulation groove 22, and a plurality of filter holes are provided on the filter plate 23. The filter plate 23 is detachably connected in the following manner: a plurality of protrusions 221 are fixed on the same horizontal plane at the top of the liquid accumulation groove 22, and the filter plate 23 is placed on the protrusions 221 to facilitate the removal and cleaning of the filter plate 23. In addition, after installation, the bottom surface of the transition plate is flush with the lowest point of the inclined surface 21, and the thickness of the transition plate is greater than or equal to 1 cm. A plurality of one-way valves 24 are arranged at intervals between the liquid accumulation trough 22 and the preservative liquid pool 1 for communication. The one-way valves 24 only allow the liquid in the liquid accumulation trough 22 to flow into the preservative liquid pool 1, and at the same time control the height of the preservative liquid in the liquid accumulation trough 22 not to be higher than the liquid outlet of the one-way valve 24. The liquid inlet of the one-way valve 24 is located at the bottom of the liquid accumulation trough 22, so that the preservative liquid collected in the liquid accumulation trough 22 can flow into the preservative liquid pool 1 in time.

[0033] After the steel mesh is soaked in the anti-corrosion liquid pool 1, it is driven by the mobile unit to move to the top of the recovery pool 2 and remain stationary for a period of time. The anti-corrosion liquid attached to the steel bars drips onto the inclined surface 21 and flows downward into the liquid accumulation tank 22. The filter plate 23 filters the collected anti-corrosion liquid to improve the quality of the recovered anti-corrosion liquid. Finally, the anti-corrosion liquid flows back to the anti-corrosion liquid pool 1 through the one-way valve 24 to achieve the recycling of the anti-corrosion liquid. There are impurities and a large amount of agglomerates of the solidified anti-corrosion liquid in the recovered anti-corrosion liquid. The impurities and agglomerates are easy to clog the filter plate 23, reducing the effective filtering amount of the filter plate 23, resulting in frequent replacement of the filter plate 23. In this embodiment, Figure 2As shown, since the filter plate 23 has a certain height, a stacking angle less than 90° is formed between the filter plate 23 and the bottom of the slope 21. After the impurities and lumps flow down with the flowing preservative liquid, they will first accumulate in the stacking angle for the first filtration, and then the liquid preservative will overflow upward and then enter the liquid accumulation tank 22 through the filter plate 23, thereby reducing the replacement demand of the filter plate 23 and further reducing the production cost of precast reinforced concrete.

[0034] The mobile unit is installed on the frame (not shown in the frame diagram), and the mobile unit includes a power rail 3, a support rail 4 and a crossbeam 5. The power rail 3 is provided with two parallel rails, and the support rail 4 is also provided with two parallel rails, and the support rails 4 are located one-to-one directly below the power rail 3. A power piece is provided in the power rail 3. In this embodiment, the power piece is a power chain 31 connected to a driving mechanism. A plurality of connection components are provided between the support rail 4 and the power rail 3, and the connection components include a crossbeam 5 and a plurality of steel chisels 6 connected to the crossbeam 5. The crossbeam 5 is rotatably and slidably connected between the support rails 4, and the connection method is specifically combined with Figure 1 As shown in the figure: a slider 41 is slidably connected on two supporting slide rails 4, and then a transverse slide rail 50 is rotatably connected between the two sliders 41 through a rotating rod 501, and then the crossbeam 5 is slidably connected to the transverse slide rail 50; and then a vertical connecting column 42 is set between the slider 41 and the power chain 31 to connect them, so that the power chain 31 drives the crossbeam 5 to move along the supporting slide rails 4. The rotation driving mode of the rotating rod 501 includes manual driving or connecting to a motor for automatic control driving.

[0035] like Figure 3 As shown, the steel drill 6 includes a lifting section 61 and a connecting section 62 which are coaxially rotatably connected. The lifting section 61 is provided with an external thread. The cross beam 5 is provided with a plurality of vertically distributed threaded holes at intervals. The steel drill 6 is threadedly connected to the threaded holes of the cross beam 5 through the lifting section 61, so that the steel drill 6 can be moved up and down relative to the cross beam 5 by rotating the lifting section 61. The lifting method of the steel drill 6 is as follows: the interior of the cross beam 5 is set as a cavity, and a nut 51 is rotatably connected to the threaded holes at the bottom of the cavity. The bottom of the nut 51 is rotatably connected to the bottom surface of the cavity. The outer periphery of the mother 51 is provided with chain teeth, and then an annular chain is arranged in the cavity (the annular chain is not shown in the figure), the annular chain is meshed with all the nuts 51, the annular chain is connected to a driving sprocket, and the driving sprocket is connected to a motor as a driving mechanism. The motor is fixed inside the crossbeam 5 by screws. When the motor is working, it can drive the annular chain to rotate clockwise or counterclockwise, thereby driving all the nuts 51 to rotate forward or reverse synchronously. The lifting sections 61 of the steel drill 6 are respectively threadedly connected to the nuts 51, thereby achieving the purpose of driving the steel drill 6 to move up or down together.

[0036] The steel bars are cross-fixed on the connecting sections 62 of the multiple rows of steel bars 6 in the multiple connecting components by means of clamps to form a steel mesh. Figure 3 As shown: a bearing 63 is set between the bottom of the lifting section 61 and the top of the connecting section 62 for rotational connection, and in order to ensure the coaxial standard between the lifting section 61 and the connecting section 62 after the connection, and to ensure the standard of the woven steel mesh, the bottom of the lifting section 61 is set to be in contact with the top of the connecting section 62 after the connection. When the anti-corrosion liquid is dipped in the steel mesh, the steel bar 6 is moved upward to move the steel mesh to the top of the recovery pool 2 for drying by immersing the steel mesh in the anti-corrosion liquid through the downward moving steel bar 6. During this process, the several connecting sections 62 are restrained by the woven steel mesh, and all the lifting sections 61 rotate to achieve upward movement: the lifting section 61 starts to rotate, and each connecting section 62, due to the limitation of the steel mesh, only generates rotational potential energy due to inertia at the beginning. This rotational potential energy causes a slight relative rotation between the connecting section 62 and the clamp, that is, during the drying period, when the steel bar 6 drives the steel mesh up and down, the connecting section 62 and the clamp can rotate slightly, thereby avoiding the problem that the connection strength between the clamp and the steel bar 6 is further increased after drying due to the adhesion of the anti-corrosion liquid itself, and the subsequent pouring of concrete pushes the clamp downward from the connecting section 62 due to excessive friction and jamming, causing damage to the connecting components.

[0037] In addition, if Figure 1 As shown, the cross beams 5 are provided with hanging holes 52, and the hanging holes 52 and the threaded holes are staggered. By providing the hanging holes 52 and the rotatable cross beams 5 on the cross beams 5, the steel bar 6 that is not needed for hanging the steel mesh can be customized to rotate 90 degrees according to the weaving requirements of different steel meshes, and then the connecting section 62 can be inserted into the hanging hole 52 to hang the group of steel bar 6 on the adjacent cross beam 5, thereby preventing the steel bar 6 that is not connected to the steel mesh from entering the antiseptic liquid pool 1 together, resulting in waste of antiseptic liquid.

[0038] When the steel mesh is fixed to the connecting section 62 by the clamp, the lifting section 61 is first controlled to move the steel bar 6 downward as a whole to facilitate the fixing operation of the steel mesh, and then the steel mesh is lifted by the steel bar 6, and then the steel mesh is driven by the power chain 31 in the power slide rail 3, and then the steel mesh is driven by the movement of the crossbeam 5 to move to the top of the anticorrosive liquid pool 1 and then lowered and immersed in the anticorrosive liquid. This solution realizes the recycling of the anticorrosive liquid by adding a recovery pool 2, avoiding the problem of waste of anticorrosive liquid caused by dripping during drying in the existing prefabricated reinforced concrete corrosion-resistant treatment system.

[0039] Example 2

[0040] like Figure 4-5The prefabricated reinforced concrete corrosion-resistant treatment system shown is different from Example 1 in that a cleaning member is connected to the power rail 3, and the cleaning member is fixed on the power chain 31, which can clean the inner wall of the power rail 3 to ensure the smooth operation of the power chain 31.

[0041] Since the production environment of precast reinforced concrete is usually poor, dust and other impurities are scattered in the environment, and the smooth operation of the power chain 31 requires spraying lubricating oil for lubrication; therefore, a large amount of silt is easily deposited in the power slide rail 3 after a long period of operation, thereby affecting the use of the power chain 31. Based on this, if Figure 4 As shown, in this embodiment, the cleaning member includes a square cleaning block 7 and support legs 70 vertically welded and fixed at the four corners of the cleaning block 7. The power chain 31 is a roller chain, which includes an inner chain plate, an outer chain plate and a pin. The support legs 70 are spot welded and fixed to the inner chain plate between the outer chain plates to complete the connection between the cleaning member and the power chain 31. After the connection, the top surface of the cleaning block 7 is in contact with the top surface of the slideway inside the power slide rail 3. When the power chain 31 starts to move, it can drive the cleaning block to move close to the inner wall of the slideway, thereby removing the sludge adhering to the power slide rail 3.

[0042] At the same time, the width of the cleaning block 7 is set to be the same as the width of the inner groove wall of the power slide rail 3, that is, after the cleaning piece is installed, the side wall of the cleaning block 7 is also in contact with the side wall of the power slide rail 3, so that when the power chain 31 is working, the cleaning piece that moves therewith can also limit the power chain 31 moving in the groove, thereby reducing the shaking of the power chain 31 during the movement, thereby improving the stability of the mobile unit operation.

[0043] like Figure 5 As shown, a through groove is provided inside the cleaning block 7, and the cleaning block 7 includes a top plate 71, a bottom plate 72 and two side plates 73. The support legs 70 are welded and fixed on the bottom plate 72. The top plate 71 is vertically slidably connected to the bottom plate 72 by setting a plurality of telescopic rods 75. The telescopic rods 75 are evenly distributed between the top plate 71 and the bottom plate 72, and compression springs are vertically fixed inside the telescopic rods 75. At the same time, multiple connection holes are opened on both sides of the top plate 71, and multiple connection blocks are fixed on the top of the side plates 73. The connection blocks are slidably connected to the connection holes one by one, so as to further improve the stability of the connection between the top plate 71 and the bottom plate 72 and the side plates 73 during the sliding of the cleaning member; a baffle plate 74 is welded and fixed on both sides of the bottom plate 72, and the width of the baffle plate 74 is the same as the width of the inner wall of the groove of the power slide rail 3. The added baffle plate 74 can not only receive the sludge scraped off by the top plate 71 and the side plates 73 to prevent the sludge from falling downwards, but also increase the length of the entire cleaning block 7, thereby further improving the effect of the cleaning block 7 on improving the stability of the power chain 31 when it moves.

[0044] In addition, when the cleaning piece is in use, there will be a large friction between the top plate 71 and the bottom surface of the groove of the power slide rail 3 due to the silt. When wear occurs, the top plate 71 will be continuously pushed upward under the action of the compression spring inside the telescopic rod 75 to compensate for the wear on the top surface of the top plate 71, so that the top plate 71 is always in contact with the power slide rail 3 to ensure the cleaning effect. The staff can clean the silt inside the cleaning block 7 regularly and replace the cleaning piece when it is worn to a large extent.

[0045] Example 3

[0046] like Figure 6 The prefabricated reinforced concrete corrosion-resistant treatment system shown is different from Example 1 in that a combined bearing 630 is provided as the bearing, and guide bars 631 are symmetrically provided on the outer surface of the combined bearing 630, and the guide bars 631 are all in a straight line state. After the guide bars 631 are fixed, they can rotate relative to the lifting section 61; accordingly, symmetrical guide grooves 521 are provided on both sides of the hanging hole 52.

[0047] In view of different steel mesh weaving requirements, in actual use, there is a situation where part of the steel bar 6 is hung. During the temporary storage period when the steel bar is hung on the adjacent beam 5, the steel bar 6 is bent due to its own gravity, which will affect the shape and standard of the woven steel mesh, and in serious cases, affect the factory quality of the reinforced concrete prefabricated parts.

[0048] Based on this, in this embodiment, Figure 6 As shown, when the group of connecting components is not needed, all the connecting sections 62 of the steel chisel 6 are removed for calibration, and the combined bearing 630 is connected to the lifting section 61. At this time, the lifting section 61 is calibrated using the combined bearing 630 and the hanging hole 52. Specifically, after the crossbeam 5 is rotated 90° as a whole, all the lifting sections 61 are driven by the lifting chain to move closer to the hanging holes 52 on the adjacent crossbeams 5. If the group of lifting sections 61 can synchronously drive the guide strips 631 on the combined bearing 630 to fit into the guide grooves 521 on both sides of the hanging hole 52 after the rotation ( The insertion process can be assisted by manual rotation of the outer ring of the combined bearing 630, so that the guide bar 631 rotates in the same direction as the guide groove 521, and then judged whether both guide bars 631 can enter the guide groove 521), which indicates that the lifting section 61 in the group of steel chisels 6 has not been deformed, and the standard of the woven steel mesh can be guaranteed; if part or all of the lifting sections 61 cannot drive the guide bars 631 on the combined bearing 630 to enter the guide groove 521 smoothly, it indicates that the lifting section 61 has been bent and deformed, and needs to be replaced to ensure the standard of the woven steel mesh. At the same time, the additional guide bar 631 shares the gravity of the combined bearing 630 during the hanging period, thereby further reducing the bending deformation of the steel chisel 6.

[0049] The above is only an embodiment of the present invention, and the common knowledge such as the known specific technical solutions and / or characteristics in the solution is not described in detail here. It should be pointed out that for those skilled in the art, without departing from the technical solution of the present invention, several modifications and improvements can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent.
