Description

Technical Field

[0001] The utility model belongs to the technical field of concrete plate production and processing, and more specifically relates to an anti-corrosion lifting device for steel mesh. Background Art

[0002] Aerated concrete board is a new type of lightweight, porous, green and environmentally friendly building material with cement, lime, silica sand and other raw materials as the main raw materials, and different amounts of anti-corrosion treated steel mesh are added according to the structural requirements. It is cured by high temperature, high pressure and steam to produce autoclaved aerated concrete board with porous crystals. Its density is smaller than that of general cementitious materials, and it has unparalleled properties such as good fire resistance, fire prevention, sound insulation, heat insulation and thermal insulation.

[0003] At present, in the production line of aerated concrete panels, the mesh cages / meshes need to be treated with anti-corrosion before being placed in the blank to prevent the mesh cages / meshes from being corroded by the chemical components of the slurry in the model car. Therefore, the anti-corrosion of the steel mesh cages / meshes is a very important process in the entire panel circulation process.

[0004] The traditional operation is to manually place the prepared steel mesh or steel mesh cage / mesh into the anti-corrosion pool for anti-corrosion treatment. This manual transfer operation is labor-intensive and inefficient. In order to improve the efficiency of the anti-corrosion operation of the steel mesh cage / mesh, many existing companies first hang the prepared steel mesh cage / mesh on the saddle frame, and then use the lifting equipment to transfer the entire saddle frame as a whole. However, when the existing lifting equipment moves horizontally, it lacks the positioning effect with the corresponding sliding track, so that the lifting equipment and the saddle frame will have a certain offset in the vertical direction, thereby affecting the assembly efficiency of the two.

[0005] After searching, the application case with Chinese patent publication number CN 217046898 U discloses a saddle frame circulation system and an aerated concrete production line. In this application, the saddle frame circulation system also includes an anti-corrosion station and an anti-corrosion crane. The anti-corrosion station is arranged at the output end of the anti-corrosion buffer line, and the anti-corrosion crane can lift the saddle frame on the anti-corrosion buffer line to the anti-corrosion station.

[0006] For another example, the application with Chinese patent publication number CN 212953968 U discloses an anti-corrosion device for steel mesh cages of aerated concrete plates.

[0007] Although the above applications can improve the efficiency of steel mesh cage / mesh anti-corrosion operations, the problem that the lifting equipment and the saddle seat are prone to a certain amount of offset in the vertical direction, thereby affecting the rapid assembly of the two, has not been effectively solved.

[0048] The utility model is further described below in conjunction with specific embodiments.

[0049] Example 1

[0050] like Figure 1 , Figure 2 As shown, an anti-corrosion lifting device for steel mesh of this embodiment includes a lifting mechanism 1, a positioning mechanism 2 and a beam frame 4. The beam frame 4 is used as an installation base and is erected above the anti-corrosion pool (not shown in the figure).

[0051] The lifting mechanism 1 is slidably arranged on the beam frame 4, and its sliding direction is horizontal. The lifting mechanism 1 is used to drive the saddle frame seat 5 to lift and move in the vertical direction.

[0052] The positioning mechanism 2 is used to position the lifting mechanism 1 after sliding to a specified position, so as to ensure the stability between the lifting mechanism 1 and the beam frame 4 and the accuracy of the position between the two.

[0053] refer to Figure 3 , Figure 4 As shown, the positioning mechanism 2 includes a first cylinder 21 and a positioning rod 22 connected to the output shaft of the first cylinder 21, and the beam frame 4 is provided with a positioning groove 23 for the positioning rod 22 to be inserted into.

[0054] Specifically, the first cylinder 21 is installed at two ends of the lifting mechanism 1 through a cylinder seat and moves synchronously with the lifting mechanism 1 , and the positioning groove 23 is arranged on the side of the beam frame 4 .

[0055] The present embodiment is an anti-corrosion lifting device for steel mesh. When the lifting mechanism 1 moves to the specified position along the beam 4, the first cylinder 21 drives the positioning rod 22 to be inserted into the positioning groove 23, so that the connection between the two is more stable and the positioning is more precise. This can effectively prevent the deviation of the position of the lifting mechanism 1 from interfering with the subsequent assembly between the lifting mechanism 1 and the saddle frame seat 5, which is beneficial to improving the assembly efficiency.

[0056] Example 2

[0057] In order to further facilitate the plug-in fit between the positioning rod 22 and the positioning groove 23. Figure 4 As shown, in this embodiment, the positioning groove 23 is provided with a trumpet-shaped opening, and a roller is provided at the end of the positioning rod 22 .

[0058] In addition, in order to prevent the risk of bending and damage to the driving rod of the first cylinder 21 due to the position deviation between the positioning rod 22 and the positioning groove 23. Figure 3 As shown, the positioning rod 22 is connected to the output shaft of the first cylinder 21 via a floating joint 24 .

[0059] The present embodiment is an anti-corrosion lifting device for a steel mesh. By providing a floating joint 24, the eccentricity of the driving cylinder can be reduced, thereby reducing the risk of bending and damage of the driving rod and increasing its service life.

[0060] Example 3

[0061] The anti-corrosion lifting device for steel mesh of this embodiment is further provided with a hanger mechanism 3 on the basis of the above embodiment. The hanger mechanism 3 is connected to the lifting mechanism 1, and the lifting mechanism 1 performs a lifting operation on the saddle frame seat 5 through the hanger mechanism 3.

[0062] refer to Figure 2 , Figure 5As shown, the hanger mechanism 3 includes a hanger body 31 and a latch assembly 32 .

[0063] Among them, a connecting head for connecting with the lifting mechanism 1 is provided above the hanger body 31. The connection form of the connecting head is the existing technology and will not be repeated here.

[0064] The latch assembly 32 is installed at the bottom of the hanger body 31 through a bracket for connecting with the saddle seat 5 .

[0065] Specifically, refer to Figure 6 , Figure 7 , Figure 8 As shown, the latch assembly 32 includes a second cylinder 321 , a latch 322 and a positioning block 323 .

[0066] The positioning block 323 is a hollow structure surrounded by three positioning plates. The two side plates of the positioning block 323 are provided with through holes for the plug pin 322 to pass through, and the bottom thereof is provided with a through hole 3231 for the cone pin 51 to pass through.

[0067] One end of the latch pin 322 is connected to the output shaft of the second cylinder 321 , and the other end is slidably disposed in a through hole on the positioning block 323 close to the side wall of the second cylinder 321 .

[0068] Specifically in this embodiment, the hanger body 31 is in an I-shape as a whole, and the latch assembly 32 is arranged at the bottom of its flange, and each flange bottom is provided with two latch assemblies 32. In other words, four connection points are arranged between the hanger mechanism 3 and the saddle frame seat 5.

[0069] In the present embodiment, an anti-corrosion lifting device for a steel mesh is used. During assembly, the lifting mechanism 1 drives the hanger mechanism 3 to descend. At this time, the cone pin 51 on the saddle seat 5 is inserted into the positioning block 323 through the through hole 3231.

[0070] Then, the second cylinder 321 is started to drive the latch pin 322 to move laterally. The end of the latch pin 322 passes through the positioning hole on the cone pin 51 and extends to the through hole on the side wall of the positioning block 323 away from the second cylinder 321 to complete the locking operation of the saddle seat 5.

[0071] Example 4

[0072] As a specific implementation of the lifting mechanism 1.

[0073] like Fig. 9 As shown, an anti-corrosion lifting device for a steel mesh in this embodiment includes a mounting base 11 on which a lifting motor 12, a synchronization component 13 and a guide component 14 are provided.

[0074] The synchronous assembly 13 is provided with two, which are respectively located at the front and rear sides of the lifting motor 12 (with Fig. 9 The lifting motor 12 is used to drive the two synchronous components 13 to rotate synchronously at the same time.

[0075] The synchronization component 13 is provided with two winding areas 15, each of which is provided with a traction rope 16, and a guide component 14 is provided on the left and right sides of the synchronization component 13. The free end of the traction rope 16 bypasses the corresponding guide component 14 and extends to the bottom of the mounting base 11 for connecting to the hanger body 31.

[0076] That is, each synchronization component 13 can drive the traction ropes 16 on both sides which are 180° in opposite directions to be curled and wound synchronously. Specifically in this embodiment, the traction ropes 16 are traction steel belts.

[0077] The anti-corrosion lifting device for steel mesh of this embodiment adopts a lifting method of winding and curling the traction rope 16, replacing the traditional chain-type lifting method, which can effectively reduce the noise pollution generated during the lifting process and is conducive to saving installation space. In addition, in this embodiment, four traction ropes 16 can form four lifting points, and the four traction ropes 16 are synchronously curled by the same lifting motor 12, which can ensure the stability of the hoisted object during the lifting process.

[0078] Example 5

[0079] This embodiment is an implementation method of the synchronization component 13.

[0080] refer to Fig.10 As shown, this embodiment is an anti-corrosion lifting device for a steel mesh, wherein the synchronization component 13 includes a synchronization shaft 131 , a winding roller 132 and a limit plate 133 .

[0081] The synchronous shaft 131 is arranged on the mounting base 11 through a bearing seat, and its end is connected to the output shaft of the lifting motor 12.

[0082] The winding roller 132 is sleeved on the synchronous shaft 131, and two winding rollers 132 are provided. The winding roller 132 and the synchronous shaft 131 can be matched through a keyway to achieve synchronous rotation.

[0083] Two limiting plates 133 are disposed on each winding roller 132 , and the winding roller 132 and the two limiting plates 133 thereon form the above-mentioned winding area 15 .

[0084] At the same time, in order to ensure the smoothness of the winding roller 132 when curling the traction rope 16, the winding roller 132 is cylindrical as a whole.

[0085] The present embodiment is an anti-corrosion lifting device for steel mesh, which can limit the winding of the traction rope 16 within the winding area 15. At the same time, by controlling the distance between the two limit plates 133, the traction rope 16 is wound in a single layer in sequence, which can effectively reduce the fluctuation caused by the misplaced winding of the traction rope 16 and further improve the stability during the lifting operation.

[0086] Example 6

[0087] Since the traction rope 16 is driven by and wound around the winding roller 132 , the end of the traction rope 16 needs to be fixed to the winding roller 132 .

[0088] The conventional operation mode is to provide mutually matching connectors, such as buckles, snap rings, etc., on the outer surface of the winding roller 132 and the end of the traction rope 16. However, this will form a raised part at the connection between the two, thereby affecting the stability of the curling operation.

[0089] To this end, in this embodiment, the specific structure of the winding roller 132 is further optimized to overcome the above problems.

[0090] Specifically, refer to Fig.11 As shown, the winding roller 132 adopts a split design, which includes a first pressure block 1321 and a second pressure block 1322 distributed up and down; wherein the second pressure block 1322 is used to connect with the synchronization shaft 131, and a gap is left between the two pressure blocks for the end of the traction rope 16 to be inserted.

[0091] The first pressing block 1321 and the second pressing block 1322 are connected by bolts, and the size of the gap is adjusted by the bolts to tighten the end of the traction rope 16.

[0092] The present embodiment is an anti-corrosion lifting device for steel mesh, wherein the winding roller 132 is divided into an upper part and a lower part, with a gap left between the two parts for the end of the traction rope 16 to be inserted into, so that the upper and lower parts are combined and the traction rope 16 is pressed to form a cylindrical shape, and the surface of the cylindrical shape has no obvious protrusions, so that the curling operation of the traction rope 16 tends to be stable and smooth.

[0093] Example 7

[0094] This embodiment is an implementation method of the guide assembly 14.

[0095] refer to Fig.12 As shown, the guide assembly 14 includes a guide shaft 141 and a seat bearing 142 .

[0096] There are two seat bearings 142 , and both ends of the guide shaft 141 are rotatably disposed in the corresponding seat bearings 142 .

[0097] In addition, two stop blocks 143 are provided on the guide shaft 141 , and the traction rope 16 is limited between the two stop blocks 143 .

[0098] The anti-corrosion lifting device for steel mesh of the present embodiment can change the direction of the traction rope 16 by rotating the guide shaft 141, and can also help reduce the friction between the two, so as to extend the service life of the traction rope 16. At the same time, the two stop blocks 143 can effectively eliminate the interference to the lifting stability caused by the left and right swing of the traction rope 16.

[0099] In addition, refer to Fig. 9 , Fig.13 The beam frame 4 is connected to the vertical lifting mechanism through a sliding assembly 17. Specifically, the sliding assembly 17 includes a guide rail 171 and a main pulley 172. The guide rail 171 is arranged at the top of both sides of the beam frame 4, and the main pulley 172 is arranged at the bottom of the mounting base 11, and the main pulley 172 is clamped on the guide rail 171.

[0100] Of course, the sliding assembly 17 also needs to be connected to a driving mechanism for driving it to slide along the guide rail 171. The driving mechanism here can adopt an existing structure, which will not be described in detail here.

[0101] In addition, in order to further improve the stability and safety of the movement of the entire lifting mechanism, a pair of auxiliary pulleys 173 are further provided at the bottom of the mounting base 11 , and the two auxiliary pulleys 173 are respectively located on both sides of the guide rail 171 .

[0102] The above schematically describes the present invention and its implementation methods, which are not restrictive. The drawings show only one implementation method of the present invention, and the actual structure is not limited thereto. Therefore, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the present invention, they should all fall within the protection scope of the present invention.
