Description

Technical Field

[0001] The utility model belongs to the technical field of round steel bar processing, and specifically relates to a supporting bracket used for assisting the straightening of round steel bars. Background Art

[0002] In underground mining operations, a large number of tunnels need to be excavated underground to provide space for transportation, ventilation, drainage, pedestrians, etc. In order to keep the tunnels unobstructed and the surrounding rocks stable, the tunnels need to be supported, that is, by applying supporting materials and structures on the tunnel walls and roofs to share and conduct the ground pressure around the tunnels. Among them, the supporting materials include steel meshes used in conjunction with concrete, which requires a large number of round steel bars for welding to make steel meshes. Before the round steel bars are welded into steel meshes, they need to be straightened and cut by a steel straightening machine; currently, for the straightening of round steel bars, bundles of round steel bars are usually stacked or leaned against the ground, and then each circle of each bundle of round steel bars is manually straightened and put into the steel straightening machine.

[0003] However, since the steel bar straightening machine operates quickly and continuously, if the speed of manually straightening the steel bars cannot keep up with the feeding speed of the straightening machine in time, the straightened steel bars to be straightened and the unstraightened steel bars will be cross-entangled. This requires cutting the steel bars from the cross-entanglement to restart the straightening operation, which not only affects the efficiency of straightening the coiled steel bars, but also easily produces a large number of inconvenient broken steel bar segments and causes waste of steel bars; secondly, the entire straightening operation requires at least two people to operate the straightening machine and straighten the steel bars respectively, with low operation efficiency, time-consuming and labor-intensive; in addition, when manually straightening the coiled steel bars, it is easy for the restraint force between the circles of coiled steel bars to cause the steel bars to be subjected to irregular force under the tension of the straightening machine, resulting in irregular bouncing of the steel bars, which can easily cause harm to the operator who is straightening the steel bars, posing a major safety hazard.

[0025] In the prior art, the straightening operation of coiled round steel bars requires manual straightening of the steel bars. There is a problem that the straightened steel bars to be straightened and the unstraightened steel bars will be cross-entangled, affecting the efficiency of the straightening of the coiled round steel bars and easily causing waste of steel bars. In addition, manual straightening of the coiled round steel bars is likely to cause harm to the operators, posing a major safety hazard, low operating efficiency, and time-consuming and labor-intensive problems.

[0026] In view of the above problems, the present application makes improvements and innovations and proposes the following embodiments.

[0027] In some embodiments, see Figure 1-Figure 4 A support bracket for assisting the straightening of a round steel bar is provided, comprising a base frame 2, a guide rod 3, a support rod 4, a fixed wheel axle 5, a roller 6, and a pull rod frame 7. The base frame 2 comprises a plurality of cross bars 201 and a longitudinal bar 202 arranged in a vertical cross array. The projection of the base frame 2 on a horizontal plane is rectangular. The length direction of the cross bar 201 is consistent with the length direction of the base frame 2. The longitudinal bar 202 is perpendicular to the cross bar 201 and fixedly installed at the bottom of the cross bar 201. The guide rod 3 is fixedly installed on the left side of the top of the cross bar 201 located in the center of the base frame 2. The guide rod 3 is a vertical rod with a plurality of guide wheels, and a support rod 4 is fixedly installed obliquely between the lower end of the guide rod 3 and the right end of the cross bar 201 located in the center of the base frame 2. The projections of the guide rod 3, the support rod 4 and the cross bar 201 located in the center of the base frame 2 on the horizontal plane are in the same straight line. A roller 6 is installed on the left end of the base frame 2 through a fixed wheel axle 5, and a pull rod frame 7 is fixedly installed on the right end of the base frame 2. A bundle of round steel bars 1 is piled on the ground through the guide rod 3 and obliquely leaned on the base frame 2 and the support rod 4. The round steel bars 1 to be straightened are stretched along the guide rod 3 and introduced into the feed port of the steel bar straightening machine.

[0028] In this embodiment, by arranging rollers 6 and pull rod frames 7 on the base frame 2, the base frame 2 part of the support bracket can be lifted by the pull rod frames 7, and the support bracket can be easily moved and transported by arranging the rollers 6, so that the guide rods 3 of the support bracket can be easily passed through the bundle of coiled round steel bars 1, which is simple to operate and saves time and effort. Specifically, when the straightening operation of the coiled round steel bars 1 starts or the next straightening operation is carried out, the support bracket is first transported to a predetermined location, so that the guide rods 3 face the direction of the feed port of the steel bar straightening machine, and the support bracket is separated from the steel bar straightening machine by a distance, and the support bracket is moved to a position away from the steel bar straightening machine by manually lifting the pull rod frames 7. The bundle of round steel bars 1 is placed in a certain position, and then a bundle of round steel bars 1 is hoisted to the front of the feed port of the steel bar straightening machine, and is placed on the ground in a way that the middle through hole of the bundle of round steel bars 1 is axially parallel to the ground. Then the pull rod frame 7 is manually lifted to move the supporting bracket back to the predetermined position. During the movement, the guide rod 3 passes through the bundle of round steel bars 1, and then the bundle of round steel bars 1 is pushed down, so that the bundle of round steel bars 1 is piled on the ground and tilted against the base frame 2 and the support rod 4. Finally, the binding belt of the bundle of round steel bars 1 is untied and the end of the bundle of round steel bars 1 is found. The end of the bundle of round steel bars 1 is stretched along the guide rod 3 and introduced into the feed port of the steel bar straightening machine, and the steel bar straightening machine can be started to start the straightening operation.

[0029] In this embodiment, by making the length direction of the cross bar 201 consistent with the length direction of the base frame 2, the cross bar 201 can form an effective support for each circle of the coiled round steel bar 1, and the coiled round steel bar 1 can be prevented from being stuck on the base frame 2; by obliquely fixing the support rod 4 between the lower end of the guide rod 3 and the right end of the cross bar 201 located in the center of the base frame 2, so that the middle position of the coiled round steel bar 1 placed on the base frame 2 can be supported by the support rod 4, so that the coiled round steel bar 1 can slide smoothly onto the guide rod 3, thereby facilitating the steel bar straightening machine to pull the coiled round steel bar 1; by making the projections of the guide rod 3, the support rod 4, and the cross bar 201 located in the center of the base frame 2 on the horizontal plane be on the same straight line, the coiled round steel bar 1 can be pulled by the steel bar straightening machine and supported by the support rod 4. The steel bar 1 can move smoothly from the base frame 2 to the guide rod 3 and enter the steel bar straightening machine smoothly and smoothly under the guidance of the guide rod 3, which can effectively prevent the straightened steel bars to be straightened from being cross-entangled with the unstraightened steel bars.

[0030] In this way, by passing the guide rod 3 through the bundle of coiled round steel bars 1, the bundle of coiled round steel bars 1 is piled on the ground and tilted against the base frame 2 and the support rod 4. The coiled round steel bars 1 to be straightened can be pulled by the base frame 2 and moved smoothly from the base frame 2 to the guide rod 3 under the support of the support rod 4 and enter the steel bar straightening machine smoothly under the guidance of the guide rod 3. The cross-winding of the coiled round steel bars 1 can be effectively avoided, and the shutdown of the steel bar straightening machine due to the cross-winding of the steel bars can be avoided, thereby effectively improving the straightening efficiency and effectively reducing the generation of broken steel bar segments and reducing the waste of steel bars. At the same time, there is no need to manually straighten the steel bars. Only one person is required to operate the supporting bracket and the steel bar straightening machine in turn to complete the straightening operation, which saves time and effort, avoids the problem that manual straightening of the steel bars can easily cause harm to the operator, and eliminates the safety hazards of manual straightening of the steel bars.

[0031] In some embodiments, see Figure 1 , Figure 2 , Figure 3 The guide rod 3 is a cylindrical tubular structure, and the projection of the guide rod 3 on the vertical plane is a downward curved arc, which can effectively reduce the friction force on the coiled round steel bar 1 when it slides on the guide rod 3, thereby facilitating the steel bar straightening function to pull the coiled round steel bar 1 more smoothly, and can further avoid the cross-entanglement of the coiled round steel bar 1 during the pulling process.

[0032] In some embodiments, see Figure 1 , Figure 2 , Figure 3 The upper end of the guide rod 3 is also connected to a downwardly bent sliding rod 8, which is a cylindrical tubular structure with the same diameter as the guide rod 3, so that the round steel bar 1 can be smoothly separated from the upper end of the guide rod 3 through the transition and guiding effect of the sliding rod 8; the sliding rod 8 is an arc-shaped structure with a bending radius smaller than the guide rod 3, and the height of the lower end of the sliding rod 8 is lower than the height of the upper end of the guide rod 3, that is, the bending angle of the sliding rod 8 is greater than the bending angle of the guide rod 3, so that the round steel bar 1 can be supported and guided by the sliding rod 8 after it is separated from the upper end of the guide rod 3, thereby preventing the round steel bar 1 from suddenly falling and shaking violently when it is separated from the upper end of the guide rod 3, so as to ensure that the round steel bar 1 can enter the steel bar straightening machine smoothly.

[0033] In some embodiments, see Figure 3 , Figure 4The support rod 4 is a square tube structure with a hollow interior, and an opening 401 is set on the side wall of the base frame 2 at the upper end of the support rod 4, and the upper end of the support rod 4 is clamped on the guide rod 3 through the opening 401. The upper end of the top side wall of the support rod 4 and the upper end of the bottom side wall are both placed on the guide rod 3 and fixedly connected with the guide rod 3 by welding. On the one hand, it can effectively improve the connection stability of the support rod 4 and the guide rod 3 to improve the bearing capacity of the support rod 4. On the other hand, it can effectively reduce the drop between the top side wall of the support rod 4 and the outer wall of the guide rod 3, so that the round steel bar 1 can slide smoothly from the support rod 4 to the guide rod 3; the lower end of the support rod 4 extends downward to the tie rod frame 7 and is fixedly connected to the tie rod frame 7, so as to block the gap between the right end of the base frame 2 and the tie rod frame 7 through the part connected with the tie rod frame 7 at the lower end of the support rod 4, thereby effectively preventing the round steel bar 1 from being cross-entangled due to being stuck in the gap between the right end of the base frame 2 and the tie rod frame 7, which is conducive to ensuring the orderly progress of the straightening operation of the round steel bar 1.

[0034] In some embodiments, see Figure 1-Figure 4 The left end of the cross bar 201 located in the center of the base frame 2 extends horizontally to the left for fixing the fixed wheel axle 5, and the rollers 6 are symmetrically installed at the front and rear ends of the fixed wheel axle 5 to ensure the stability of the support bracket during movement and transportation; a reinforcing plate 9 is also obliquely installed between the guide rod 3 and the fixed wheel axle 5, which can effectively improve the installation stability of the fixed wheel axle 5, so as to further improve the stability and service life of the support bracket.

[0035] In some embodiments, see Figure 3 When the base frame 2 is placed horizontally, the height of the lowest point of the roller 6 is higher than the height of the bottom surface of the base frame 2, thereby preventing the roller 6 from contacting the ground when the base frame 2 is placed horizontally, so as to improve the stability of the support bracket when the base frame 2 is placed horizontally, that is, it can ensure that the support bracket remains stable and stationary during the placement of the coiled round steel bar 1, so as to ensure that the straightening operation of the coiled round steel bar 1 is carried out smoothly.

[0036] Finally, it should be noted that although the embodiments of the utility model have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations on the utility model. Ordinary technicians in the field can make changes, modifications, substitutions and variations to the above embodiments within the scope of the utility model, which should all be included in the scope of protection of this application.
