Description

TECHNICAL FIELD

[0001] The utility model relates to the field of building engineering, especially a reinforcing steel bar feeding device. BACKGROUND

[0002] At present, in order to speed up the construction progress and save materials, steel bar truss floor slab is favored by the engineering field and is applied more and more in engineering. Among them, the steel bar truss floor slab is to process the steel bars in the floor slab into steel bar trusses in the factory, process galvanized steel plates into profiled steel plates, and then weld the steel bar trusses and galvanized steel plates into an integrated combined floor slab through resistance spot welding, so as to replace the formwork scaffold to bear the construction load in the construction stage and make the upper steel bars participate in the structural stress in the use stage. It is an economic, convenient, safe and reliable building floor material.

[0003] In recent years, the forms of steel bar truss floor slab are more and more diversified, mainly including two types of metal formwork and wooden formwork. The metal base mold can be removed or not removed, and the wooden formwork generally needs to be removed. However, if the base plate is removed, it is time-consuming and laborious, and the concrete will be exposed, which needs to be whitewashed after plastering. If the base plate is not removed, the metal base mold cannot be whitewashed, so a suspended ceiling is needed to cover the base mold. Therefore, in view of the above technical problems, the applicant has developed a removable truss plate, which embeds the lower part of the steel bar truss in the concrete slurry, and realizes the connection with the steel bar truss as the concrete slurry solidifies and forms. That is, the connection between the base plate and the steel bar truss is completed during the production of the concrete base plate, which not only avoids the complex structure of the base plate due to the connection of the connecting part of the steel bar truss, but also reduces the installation of additional connecting parts and the workload of connecting the steel bar truss and the base plate through the connecting parts.

[0004] In the production of the above-mentioned truss plate, the steel bar trusses are usually placed one by one in the mold, and then the concrete slurry is laid in the mold. After being vibrated and compacted and smoothed, it is formed. The formed truss plate can be used in building engineering. However, in actual production and processing, if the steel bar trusses are placed one by one by manual labor, the labor intensity of workers is high, the production efficiency is low, and the consistency of the spacing and height of the trusses cannot be guaranteed, thereby affecting the quality of the final truss plate. Therefore, the applicant welds multiple steel bar trusses to form a truss group, which only needs to be placed in the mold, effectively improving the production efficiency of the truss plate. However, the truss plate is mass-produced, and manual welding of the truss group still brings the problems of high labor intensity of workers and low production efficiency. In addition, it also depends on the welding technology of workers. Therefore, the applicant designs a truss group welding equipment to place the trusses on the welding platform for welding. However, if the steel cross beams are inserted into the lower part of the multiple trusses by manual labor, the labor intensity of workers is high and the degree of automation is low. Therefore, how to automatically and reliably insert the steel cross beams into the lower part of the multiple trusses becomes a technical problem. Utility Model Content

[0029] In order to better understand the purposes, functions and specific design schemes of the present application, the reinforcing steel bar feeding device of the present application is described in further detail below with reference to the accompanying drawings.

[0030] ​​​As Figures 1-10 The steel bar feeding device comprises a steel bar storage rack 1, the steel bar storage rack 1 comprises a bottom plate 2, a plurality of seat plates 3 are fixedly arranged on the bottom plate 2 in a vertical and inclined manner, the plurality of seat plates 3 are arranged in parallel, a steel bar placing table 31 is arranged on the side edge of the seat plate 3, and a steel bar cross beam can be placed in the steel bar placing table 31; a pushing table 32 is arranged at the top of the seat plate 3, a sliding plate 4 is arranged in sliding connection with the side of the seat plate 3, a jacking table 41 is arranged on the side edge of the sliding plate 4, when the sliding plate 4 slides from bottom to top, the jacking table 41 can lift the steel bar cross beam 5 in the steel bar placing table 31 into the pushing table 32, a pushing block assembly 61 is arranged above the pushing table 32, and the pushing block assembly 61 can push the steel bar cross beam 5 in the pushing table 32 out to a position to be welded. Preferably, the seat plate 3 is fixedly connected with a pushing baffle 62 matched with the shape of the pushing table 32, the pushing baffle 62 and the pushing table 32 form a pushing groove, so that the contact area of the steel bar cross beam 5 to be pushed is increased, and the steel bar cross beam 5 is prevented from falling.

[0031] Specifically, as Figures 2-9 The sliding plate 4 comprises an initial position and a lifting position, and the sliding plate 4 can repeatedly move between the initial position and the lifting position to lift the steel bar cross beam 5 in the steel bar placing table 31 into the pushing table 32 one by one. The steel bar placing table 31 of the embodiment comprises a placing surface 311 and a stop surface 312 connected with each other, the jacking table 41 comprises a bearing surface 411 and a limiting surface 412 connected with each other, and the pushing table 32 comprises a rolling surface 321 and a stop surface 323 connected with each other; when the sliding plate 4 is at the initial position, the bearing surface 411 is parallel to the placing surface 311 and located below the placing surface 311, and the limiting surface 412 is parallel to the stop surface 312 and located in front of the stop surface 312; when the sliding plate 4 moves from the initial position to the lifting position, the bearing surface 411 lifts the steel bar cross beam 5 in the placing table 31 upward; it is worth noting that the distance between the limiting surface 412 and the stop surface 312 is greater than the radius of the steel bar cross beam 5 and less than 1.5 times the radius of the steel bar cross beam 5, so that the jacking table 41 only lifts one steel bar cross beam 5 at a time. When the sliding plate 4 is at the lifting position, the bearing surface 411 is parallel to the rolling surface 321 and located above the rolling surface 321; when the sliding plate 4 moves from the lifting position to the initial position, that is, when the sliding plate 4 moves downward, the steel bar cross beam 5 on the bearing surface 411 falls onto the stop surface 323 and rolls toward the rolling surface 321 until the steel bar cross beam 5 abuts against the rolling surface 321, so that the lifting of the steel bar cross beam 5 is completed.

[0032] Preferably, the quantity of the reinforcing steel bar placing tables 31 is multiple, and the reinforcing steel bar placing tables 31 are arranged on the side edges of the seat plate 3. The reinforcing steel bar storage grooves 33 are arranged at positions below the side edges of the seat plate 3. The reinforcing steel bar storage grooves 33 can store multiple reinforcing steel bar beams 5. The jacking tables 41 are arranged on the sliding plate 4, and the jacking tables 41 correspond to the reinforcing steel bar placing tables 31 and the reinforcing steel bar storage grooves 33 in one-to-one correspondence. When the sliding plate 4 repeatedly moves between the initial position and the lifting position, the reinforcing steel bar beams 5 in the reinforcing steel bar storage grooves 33 are lifted one by one to the reinforcing steel bar placing tables 31 above. The reinforcing steel bar beams 5 in each reinforcing steel bar placing table 31 are lifted step by step, and the reinforcing steel bar beams 5 in the uppermost reinforcing steel bar placing table 31 are lifted to the pushing table 32 at the top. By arranging multiple reinforcing steel bar placing tables 31, the distance of the repeated movement of the sliding plate 4 can be reduced, the reliability of the lifting of the reinforcing steel bar beams 5 can be improved, and the probability of the falling of the reinforcing steel bar beams 5 during the lifting can be reduced.

[0033] The reinforcing steel bar storage groove 33 is in a V shape, and the reinforcing steel bar storage groove 33 comprises a first storage surface 331, a bottom surface 332 and a second storage surface. When the sliding plate 4 is in the initial position, the bearing surface 411 of the lowermost jacking table 41 is parallel to the bottom surface 332 and is below the bottom surface 332. The limiting surface 412 is parallel to the first storage surface 331 and is in front of the first storage surface 331. Preferably, the length of the bottom surface 332 is equal to the diameter of the reinforcing steel bar beam 5, so that only one reinforcing steel bar beam 5 can be accommodated on the bottom surface 332. The distance between the limiting surface 412 and the first storage surface 331 is greater than the radius of the reinforcing steel bar beam 5 and less than 1.5 times the radius of the reinforcing steel bar beam 5, so that the jacking table 41 only lifts one reinforcing steel bar beam 5 at a time. It is worth noting that when the sliding plate 4 is in the initial position, the limiting surface 412 of the jacking table 41 adjacent to the lowermost jacking table 41 is parallel to the first storage surface 331 and is behind the first storage surface 331, so as to avoid affecting the lifting of the reinforcing steel bar beam 5.

[0034] When the sliding plate 4 is in the lifting position, the bearing surface 411 of the lowermost jacking table 41 is parallel to the placing surface 311 of the lowermost reinforcing steel bar placing table 31 and is above the placing surface 311. When the sliding plate 4 moves from the lifting position to the initial position, that is, when the sliding plate 4 moves downward, the reinforcing steel bar beam 5 on the bearing surface 411 falls onto the placing surface 311 and rolls towards the stop surface 312 until the reinforcing steel bar beam 5 abuts against the stop surface 312, so as to complete the lifting of the reinforcing steel bar beam 5.

[0035] It is worth noting that when the sliding plate 4 moves downward, since the limiting surface 412 of the lowermost lifting platform 41 is parallel to the first storage surface 331 and is located in front of the first storage surface 331, only when the sliding plate 4 returns to the initial position, the steel bar beam 5 in the steel bar storage groove 33 can roll onto the bottom plate 2. Similarly, since the stop surface 312 of each stage of steel bar placing platform 31 is parallel to the limiting surface 412 of the corresponding stage of lifting platform 41, and the limiting surface 412 is located in front of the stop surface 312, only when the sliding plate 4 returns to the initial position, the steel bar beam 5 on the placing surface 311 of the steel bar placing platform 31 can roll to the position abutting against the stop surface 312.

[0036] All the sliding plates 4 of the present embodiment are connected with the driving assembly 7, which can drive the sliding plate 4 to move up and down repeatedly. The driving assembly 7 includes a lifting cylinder 71 fixed on the bottom plate 2 or the seat plate 3, a lifting rod 72 connected with the lifting cylinder 71, and each sliding plate 4 fixedly connected with the lifting rod 72. Through the extension and contraction of the lifting cylinder 71, the sliding plate 4 can move repeatedly between the initial position and the lifting position. Preferably, a stroke limiting groove 42 is arranged on the sliding plate 4, and a stroke limiting column 34 is arranged on the seat plate 3 and inserted into the stroke limiting groove 42. When the sliding plate 4 is in the initial position, the stroke limiting column 34 is located at the lower position of the stroke limiting groove 42, and when the sliding plate 4 is in the lifting position, the stroke limiting column 34 is located at the upper position of the stroke limiting groove 42. By arranging the stroke limiting groove 42, the position accuracy of the repeated movement of the sliding plate 4 can be improved, thereby improving the accuracy and reliability of lifting the steel bar beam 5. It is worth noting that in order to reduce the resistance of the stroke limiting column 34 when moving in the stroke limiting groove 42, a bearing is sleeved outside the stroke limiting column 34.

[0037] A pushing frame 8 is arranged above the seat plate 3, and a pushing assembly 81 is arranged on the pushing frame 8. The pushing assembly 81 is connected with the pushing block assembly 61 and can drive the pushing block assembly 61 to move reciprocatingly to push the steel bar beam 5 in the pushing platform 32 to the welding position. The pushing assembly 81 of the present embodiment includes a pushing cylinder connected with the pushing block assembly 61, and the pushing cylinder drives the pushing block assembly 61 to move reciprocatingly. The pushing cylinder can be a rodless cylinder.

[0038] As shown in Figure 4 the pushing block assembly 61 includes a pushing block support 611 and a pushing plate 612. The pushing block support 611 is connected with the pushing cylinder, and the end of the pushing block support 611 away from the pushing cylinder extends towards the pushing platform 32. The pushing plate 612 is fixedly arranged at the end of the pushing block support 611 away from the pushing cylinder and perpendicular to the moving direction of the pushing block support 611. The area of the pushing plate 612 is greater than the cross-sectional area of the steel bar beam 5, so as to improve the reliability of pushing the steel bar beam 5.

[0039] As Figure 1 The steel bar storage rack 1 further comprises side baffle plates 9, which are two and symmetrically arranged on both sides of the seat plate 3 close to the edges of the bottom plate 2, and can prevent the steel bar cross beams 5 from falling off the seat plate 3 or the sliding plate 4. Preferably, the part corresponding to the steel bar storage groove 33 of the side baffle plate 9 is trapezoidal with a narrow bottom and a wide top, so as to limit the steel bars in the steel bar storage groove 33 and prevent the steel bar cross beams 5 in the steel bar storage groove 33 from falling out when being lifted and turned over. The position corresponding to the placement table 31 of the side baffle plate 9 is the same as the shape of the placement table 31, and the side edge surface of the side baffle plate 9 is arranged in front of the side edge surface of the seat plate 3, so as to limit the steel bars and reduce the area and weight of the side baffle plate 9.

[0040] The seat plate 3 of the embodiment is three, which are uniformly and spacedly arranged on the bottom plate 2, and correspondingly, the sliding plate 4 is also three, which are respectively and slidably arranged on the side of the seat plate 3. The driving assembly 7 is arranged on the seat plate 3 in the middle position. Preferably, in order to reduce the weight of the whole device, the seat plate 3 is provided with a hollow hole.
