Description

Technical Field

[0001] The invention relates to the technical field of prestressed frame beam casting construction equipment, in particular to a large-span prestressed frame beam casting construction pre-processing equipment. Background Art

[0002] Large-span prestressed frame beams are a common structural form in construction projects. Before the casting construction of large-span prestressed frame beams, it is necessary to first make a steel cage. A large number of steel bars are required for the production of the steel cage. Therefore, a large number of steel bars need to be cut before the production of the steel cage. The steel bar cutting operation is a necessary processing method before the construction of the steel cage of the large-span prestressed frame beam. At present, the steel bar cutting operation usually adopts the cutting method of cutting the whole bundle of steel bars together.

[0003] However, this cutting method has many problems. First, because the whole bundles of steel bars are stacked together, when cutting too many of them, the steel bars at the bottom may exceed the maximum cutting depth of the cutting blade, resulting in the steel bars at depth being unable to be effectively cut. The cutting position needs to be manually adjusted from different directions such as front, back, top and bottom multiple times, which increases the operation steps and workload. In addition, it is difficult to maintain the straightness of the cutting during multiple adjustments, which may result in an uneven cutting surface.

[0004] Secondly, the cut steel bars cannot be removed automatically and will accumulate in the cutting area. The accumulated steel bars will physically hinder the cutting blade, causing an unsmooth cutting process and possibly an uneven cutting surface. The cutting disc may be subjected to additional pressure and impact when obstructed, increasing the risk of damage to the cutting disc and causing reduced cutting quality. It will also hinder subsequent continuous cutting work and cause the cutting blade to be unable to cut smoothly. Summary of the invention

[0005] The present invention provides a processing device before casting construction of large-span prestressed frame beams, which solves many problems existing in the traditional method of cutting whole bundles of steel bars: due to the large number of steel bars, the steel bars in the bottom layer may exceed the depth of the cutting blade, and the cutting position needs to be adjusted multiple times, which increases the operation steps and workload, and it is difficult to maintain the linearity of the cutting, resulting in an uneven cutting surface. The cut steel bars cannot be automatically removed and will accumulate in the cutting area, hindering the operation of the cutting blade, increasing the risk of damage to the cutting blade, resulting in a decrease in cutting quality, and hindering subsequent continuous cutting work.

[0009] In a possible implementation, a guide groove is provided at the lower portion of the support rod, and an L-shaped guide block slidably disposed in the guide groove is fixedly connected to the side end surface of the installation frame.

[0030] See also Figure 1 The present invention provides a technical solution: a processing equipment before pouring construction of a large-span prestressed frame beam, comprising a processing seat 1, a support platform 2 is embedded and fixedly connected in the processing seat 1, a rectangular frame 3 for placing a whole bundle of steel bars so that they are arranged longitudinally and limited is fixedly connected to the upper end surface of the support platform 2, a pressure plate 4 is fixedly connected to the upper cavity wall of the rectangular frame 3 through a compression spring, a mounting frame 5 sleeved on the outside of the rectangular frame 3 is slidably connected to the front end surface of the rectangular frame 3 through a reciprocating electric telescopic column, a cutting saw 6 is rotatably connected to the mounting frame 5 through a fixed frame, and the front and rear wall panels of the rectangular frame 3 are both provided with strip-shaped through grooves 7 for the cutting saw 6 to extend into, an intermittent lifting mechanism 8 for making the mounting frame 5 intermittently move upward so as to cut the whole bundle of steel bars from bottom to top in sequence is commonly arranged between the processing seat 1 and the mounting frame 5, two supporting mechanisms 9 for gradually contacting the lower part of the whole bundle of steel bars during the cutting process are symmetrically arranged on the upper part of the processing seat 1, and an end resistance mechanism 10 for limiting the contact of the end of the steel bar is installed on the upper part of the processing seat 1.

[0031] See also Figure 3 , Figure 4 and Figure 7 In this embodiment, the intermittent lifting mechanism 8 includes two strip plates 81 symmetrically fixedly connected to the upper end surface of the processing seat 1, and the opposite sides of the two strip plates 81 are equidistantly hinged with a plurality of hinge plates 82 through lugs, and the front and rear rows of hinge plates 82 are arranged in a staggered manner. A return spring 83 is fixedly connected between the hinge plates 82 and the strip plates 81, and an embedded column 84 is fixedly connected to the side of the hinge plate 82 away from the strip plate 81, and an open-shaped block 85 for cooperating with the embedded column 84 is fixedly connected to the front and rear sides of the installation frame 5.

[0032] See also Figure 3 , Figure 7 and Figure 8The supporting mechanism 9 includes two strip slides 91 which are symmetrically fixedly connected to the upper end surface of the processing seat 1 and open on opposite sides. A supporting rod 92 is slidably connected between the two strip slides 91. A groove wall on one side of the strip slide 91 away from the supporting rod 92 is equidistantly provided with a plurality of slots 93. A wedge-shaped tongue 94 is slidably connected in each slot 93. A top spring 95 is fixedly connected between the slot 93 and the wedge-shaped tongue 94. The side groove wall of the strip slide 91 is slidably connected to the wedge-shaped tongue through a connecting spring. The tongue 94 abuts against the side wall of the tongue 94, and when the entire bundle of steel bars is cut and the supporting rod 92 moves to the highest position, it is only necessary to push the supporting rod 92 to the side to push the supporting rod 92 to move the supporting rod 96 to the side, so that a gap appears between the supporting rod 96 and the wedge-shaped tongue 94, and then press the supporting rod 92 downward to move along the gap between the supporting rod 96 and the wedge-shaped tongue 94, so that the supporting rod 92 can be quickly moved down and reset to the initial position, so as to facilitate the cutting of the next batch of whole bundles of steel bars.

[0033] See also Figure 5 , Figure 7 and Figure 8 A guide groove 11 is provided at the lower part of the supporting rod 92, and an L-shaped guide block 12 slidably arranged in the guide groove 11 is fixedly connected to the side end surface of the mounting frame 5. Material receiving seats 13 are fixedly connected to the left and right sides of the support platform 2, and a side plate 14 is fixedly connected to the edge of the upper end surface of the material receiving seat 13. The upper end surface of the material receiving seat 13 is in an inclined state where the side close to the support platform 2 is higher and the side away from the support platform 2 is lower.

[0034] When cutting a whole bundle of steel bars, they are placed in the rectangular frame 3 so that the whole bundle of steel bars is stacked and arranged in a rectangular shape under the limit of the rectangular frame 3, and then the end abutment mechanism 10 is tightly abutted against the end of the steel bar to limit its horizontal position. The lower part of the placed steel bar abuts against the supporting rod 92, and then the reciprocating electric rod is controlled to drive the installation frame 5 to reciprocate back and forth. The installation frame 5 then drives the cutting saw 6 to reciprocate in the strip-shaped through groove 7 through the fixed frame. The cutting saw 6 is driven to move back and forth through the rectangular frame 3 during the process of movement, and the steel bars at the bottom will be cut. After the installation frame 5 drives the cutting saw 6 to move from back to front and the cutting is completed, it will drive the open-shaped card block 85 to touch the top of the front. The first embedded column 84 from the bottom is used to push the hinged plate 82, so that the hinged plate 82 rotates around the lug. During the rotation of the hinged plate 82, the opening-shaped block 85 and the embedded column 84 that are in contact with each other will drive the mounting frame 5 to move up a distance. The mounting frame 5 then drives the supporting rod 92 to move up through the L-shaped guide block 12. The upward movement of the supporting rod 92 will trigger the end abutment mechanism 10 to operate and release the contact with the end of the lower steel bar in the whole bundle of steel bars. Therefore, the cut steel bars automatically fall down under gravity and fall into the receiving seat 13, and then slide in the direction away from the rectangular frame 3 under the action of the upper inclined surface of the receiving seat 13, and automatically align the ends.

[0035] After being driven to move up a certain distance, the supporting rod 92 passes over the first wedge-shaped tongue 94 from the bottom and abuts against the upper part of the wedge-shaped tongue 94. The supporting rod 92 after moving up abuts against the lower part of the uncut steel bars in the middle of the whole bundle of steel bars in the longitudinal direction. Then the mounting frame 5 starts to drive the saw 6 to move backward, and the saw 6 moves backward to cut the steel bars in the middle of the whole bundle of steel bars. During the forward and backward movement of the mounting frame 5, the L-shaped guide block 12 is driven to slide in the guide groove 11. When the saw 6 completes the cutting of the middle part of the whole bundle of steel bars stacked together, the mounting frame 5 will move to the rear and drive the open-shaped card block 85 to abut against the first embedded column 84 from the bottom at the rear, and then push the first hinged plate 82 at the bottom of the rear to rotate, and the hinge During the rotation of plate 82, the above steps are repeated again, so that the installation frame 5 moves up a distance again. After the installation frame 5 moves up a distance, it will trigger the end abutment mechanism 10 again to loosen the end of the steel bar in the middle of the whole bundle of steel bars and touch it. Then, the steel bars in the middle of the whole bundle of steel bars will fall down again after being cut. The installation frame 5 after moving up will drive the supporting rod 92 to move up synchronously through the L-shaped guide block 12, so that the supporting rod 92 moves up and passes over the next wedge-shaped tongue 94. After moving up a distance again, the supporting rod 92 abuts against the upper part of the second wedge-shaped tongue 94 from the bottom, and then the installation frame 5 moves forward again, driving the cutting saw 6 to move forward through the rectangular frame 3, and repeating the above steps to cut the steel bars in the upper part of the whole bundle of steel bars.

[0036] The cutting method in which the saw 6 moves intermittently from bottom to top can effectively avoid the situation in which the cutting position needs to be adjusted multiple times due to the bottom layer of steel bars exceeding the depth of the cutting blade, thereby improving the cutting efficiency. There is no need to frequently adjust the cutting position, reducing the operating steps and workload, simplifying the operating process, and ensuring the linearity of the cutting process and the flatness of the cutting surface. After cutting, the steel bars are automatically dropped and removed by their own gravity, avoiding the situation in which the steel bars are piled up in the cutting area after cutting and hindering the saw 6. There is no accumulation of steel bars in the cutting area, and the saw 6 can work smoothly, reducing the additional pressure and impact caused by obstruction and increasing the service life of the cutting blade. The automated cutting and removal process realizes continuous operation and improves overall work efficiency.

[0037] See also Figure 1In this embodiment, the end abutment mechanism 10 includes two support plates 101 symmetrically fixedly connected to the upper end surface of the processing seat 1, the opposite sides of the two support plates 101 are slidably connected with the mounting plates 102 through spring telescopic rods, and the lower part of the mounting plates 102 is hinged with a plurality of top contact plates 103 equidistantly along the longitudinal direction, and the mounting plates 102 and the top contact plates 103 are respectively fixedly connected with a ring 104 on one side close to the support plates 101, and the rings 104 located on the same side in the longitudinal direction are slidably connected with a limiting rod 105, and a synchronization component 106 is commonly arranged between the limiting rod 105 and the stripping rod, and the synchronization component 106 includes a Z-shaped rod 1061 fixedly connected to the outside of the limiting rod 105, and the opposite sides of the lower transverse sections of the two Z-shaped rods 1061 are commonly fixedly connected with a lifting rod 1062 that abuts against the upper part of the supporting rod 92.

[0038] After the whole bundle of steel bars is put in, the spring telescopic rod drives the top contact plate 103 to tightly contact the end of the steel bar through the mounting plate 102, so as to limit the horizontal position of the steel bar. When the mounting frame 5 drives the saw 6 to cut part of the steel bars in the whole bundle and starts to move up, the mounting frame 5 drives the supporting rod 92 to rise a certain distance through the L-shaped guide block 12. At the same time, the supporting rod 92 also drives the lifting rod 1062 to move up. The lifting rod 1062 then drives the limiting rod 105 to move up a certain distance through the Z-shaped rod 1061. The limiting rod 105 moves up a certain distance. After a certain distance, it is pulled out from the first ring 104 at the bottom, and then the first top contact plate 103 at the bottom can rotate around the top contact plate 103 hinged thereto, and stop pressing on the ends of the steel bars in the lower part of the whole bundle of steel bars, so that the cut steel bars can fall downward under gravity and move away. As the saw 6 moves upward intermittently after each cutting, the limit rod 105 will move upward synchronously, and the limit rod 105 will gradually separate from the ring 104 from bottom to top, so that the top contact plates 103 from bottom to top will stop contacting the ends of the steel bars in turn, and the cut steel bars can be automatically released.

[0039] Please refer to the figure. In this embodiment, a mounting groove is opened in the support 2, and a rectangular collecting box 15 is fixedly connected to the inner wall of the mounting groove. A conical material guide cover 16 is fixedly connected in the rectangular collecting box 15. Metal chips generated during the cutting process will fall into the mounting groove under gravity, and then fall into the conical material guide cover 16, and then roll down the inclined surface of the conical guide cover into the rectangular collecting box 15.

[0040] During operation, firstly, the whole bundle of steel bars is placed into the rectangular frame 3, and the compression spring drives the pressure plate 4 to contact the upper part of the steel bars, so that they are arranged in a rectangular shape, and the end abutment mechanism 10 contacts the end of the steel bars to limit them. Then, the reciprocating electric telescopic rod is controlled to drive the installation frame 5 to reciprocate back and forth, and the installation frame 5 then drives the cutting saw 6 to move synchronously. After the cutting saw 6 moves back and forth to cut part of the steel bars in the whole bundle of steel bars, the intermittent lifting mechanism 8 drives it to move up intermittently. When the intermittent lifting mechanism 8 rises, it cooperates with the supporting mechanism 9 and the end abutment mechanism 10 to automatically put down the cut steel bars, and drag the lower part of the steel bars to be cut to limit them. Then, the cutting saw 6 repeats the above steps again, and cuts the whole bundle of steel bars from bottom to top in turn. After cutting, the steel bars fall into the receiving seat 13 under their own gravity.
