Description

A through-length tendon positioning device

Technical Field

The invention relates to the technical field of steel bar processing equipment, and in particular to a through-length steel bar positioning device.

Background Art

T-beam top slabs are widely used in the railway field. In railway bridges, railway tunnels and other railway projects, T-beam top slabs are often used as structural elements to support railway tracks and carry train loads. T-beam top slabs usually include T-shaped steel bar skeletons as part of them. The T-shaped steel bar skeleton is an important component of the T-beam top slab structure, which is used to provide additional strength and rigidity to increase the bearing capacity and stability of the overall structure. The T-shaped steel bar skeleton is composed of a "I"-shaped steel bar skeleton and a "1"-shaped steel bar skeleton.

The steel bar skeleton of the Chinese character "一" is composed of multiple rectangular long stirrups arranged at intervals and multiple through-length bars welded together. Before welding, multiple through-length bars need to be inserted into multiple long stirrups arranged at intervals. Generally, the through-length bars are inserted from the last long stirrup through a steel bar pushing mechanism, and finally passed out from the front long stirrup. This process is called the through-length bar threading process. However, in the actual threading process, multiple through-rebars need to be inserted into many long stirrups arranged at intervals. After the through-rebars are inserted from the long stirrups at the rear end, it is often difficult to pass through the long stirrups at the front end due to the long threading path. For example, in the process of threading, when the front end of the through-rebar moves forward far (when the front end of the through-rebar is far from the steel bar pushing mechanism at the rear), after the front end of the through-rebar moves to the downward warping distance, the front end of the through-rebar will bend downward due to the deflection factor, and the through-rebar will also bend the lower side of the long stirrups that have been threaded downward, causing the front end of the through-rebar to be lower than the lower side of the long stirrups that have not been threaded in the front, which causes the front end of the through-rebar to be unable to continue to be inserted into the long stirrups in the front.

Referring to Figs. 1-3, a through-length reinforcement positioning device according to an embodiment of the present invention is used in conjunction with a long stirrup support device, wherein the long stirrup support device comprises two support units 1 spaced apart in the left-right direction, the two support units 1 are respectively used to support at both ends of a long stirrup 2, and a plurality of the long stirrups 2 are sequentially spaced apart in the front-to-back direction, the front-to-back direction is perpendicular to the left-to-right direction, and the left-to-right direction and the front-to-back direction are respectively perpendicular to the vertical direction;

In the left and right directions, the through-length reinforcement positioning device is located between the two support units 1, and the through-length reinforcement positioning device includes a base 4 and a plurality of positioning mechanisms 5 arranged on the base 4, and the plurality of positioning mechanisms 5 are arranged in sequence along the front-to-back direction, and there is at least one long stirrup 2 between two adjacent positioning mechanisms 5, and the positioning mechanism 5 includes a lifting mechanism 52 and a positioning assembly 51, and the lifting mechanism 52 is used to drive the positioning assembly 51 to rise and fall, and the spacing between the positioning assemblies 51 in adjacent positioning mechanisms 5 is smaller than the downward warping distance of the through-length reinforcement 3.

In this embodiment, the two support units 1 of the long stirrup support device can be arranged at intervals in the left-right direction, and a plurality of long stirrups 2 can be placed in sequence on the two support units 1 in the front-to-back direction in advance. Before the through-length reinforcement 3 is threaded, the plurality of positioning components 51 arranged in sequence in the front-to-back direction can be raised first, that is, the positioning components 51 are raised to a set height by the lifting mechanism 52. After that, the through-length reinforcement 3 can be pushed forward and first inserted into the long stirrup 2 at the rear end through the steel bar pushing mechanism (not shown in the figure) located behind the long stirrup 2 at the rear end. As the steel bar pushing mechanism continues to push at the rear end, before the front end of the through-length reinforcement 3 moves a downward warping distance, the front end of the through-length reinforcement 3 The end has been supported by the positioning component 51 that has risen to the set height in the rearmost positioning mechanism 5, and will not bend downward. Under the support of the positioning component 51, the through-length reinforcement 3 will not bend downward the lower side of the long stirrup 2 that has been threaded, and the spacing between the positioning components 51 in adjacent positioning mechanisms 5 can be smaller than the downward warping distance of the through-length reinforcement 3. In this way, the front end of the through-length reinforcement 3 will be supported by the positioning component 51 of the front positioning mechanism 5 in turn during the threading process, and will not bend downward the lower side of the long stirrup 2 that has been threaded, ultimately ensuring that it can pass through the frontmost long stirrup 2, making the threading of the through-length reinforcement 3 smoother, reducing the difficulty of threading and improving efficiency.

It should be noted that the downward warping distance of the through-length rib 3 refers to the situation in the prior art where the front end of the through-length rib 3 moves forward a certain distance away from the supporting position and then warps downward due to deflection problems, wherein the certain distance that the front end of the through-length rib moves forward from the supporting position is the downward warping distance.

Among them, it can be understood that the distance from the positioning component 51 in the rearmost positioning mechanism 5 to the rear steel bar pushing mechanism is less than the downward warping distance of the through-length reinforcement 3, ensuring that the front end of the through-length reinforcement 3 has not been downwardly warped before moving to the positioning component 51. The positioning component of the frontmost positioning mechanism 5 is located at the front side of the frontmost long stirrup 2 to ensure that the through-length reinforcement 3 has not been downwardly warped before passing through the frontmost long stirrup 2. Assuming that the front end of the through-length reinforcement 3 in the prior art will be downwardly warped when it moves to a distance of 600mm, that is, assuming that the downward warping distance of the through-length reinforcement 3 is 600mm, then the spacing between the positioning components 51 in adjacent positioning mechanisms 5 is, for example, 500mm, which can ensure that the front end of the through-length reinforcement 3 will not be downwardly warped when it is located between two adjacent positioning components 51.

Among them, in this embodiment, the positioning component 51 can play a supporting role; and the two supporting units 1 of the long stirrup support device can be a circulating conveying mechanism, which not only supports the two ends of the long stirrup 2, but also can realize the conveying of the long stirrup 2 to the welding mechanism in front (not shown in the figure). When all the through-length bars 3 are threaded, the positioning component 51 can be reset downward by the lifting mechanism 52 in the positioning mechanism 5. After the threading of the through-length bars 3 is completed, the front end of the through-length bars 3 is also moved to the welding mechanism in front, and the welding mechanism can support and position the front end of the through-length bars 3. After the threading of the through-length bars 3 is completed, the multiple long stirrups 2 can be sequentially conveyed to the welding mechanism through the circulating conveying mechanism, and then the through-length bars 3 are welded to the long stirrups 2 at the welding mechanism. As shown in Figure 11, the through-length bars 3 have been welded to the long stirrups 2.

It should be noted that the supporting unit 1 (or the circulating conveying mechanism) and the welding mechanism may be existing technologies and are not within the scope of improvement of the present application.

It should be noted that in the prior art, the difficulty in threading the through-long reinforcement 3 is also manifested in that during the threading process of the through-long reinforcement 3 at multiple different transverse positions, the front end portions of these through-long reinforcements 3 are easily crowded together, which leads to mutual influence, interference and obstruction between the through-long reinforcements 3, which also makes threading difficult.

In the through-length rib positioning device, optionally, referring to Figures 2 and 4, the positioning assembly 51 includes a positioning wheel 511 and a plurality of support plates 512, the support plates 512 are arranged on the lifting mechanism 52, and the plurality of support plates 512 are arranged in sequence along the left-right direction, and each of the support plates 512 is mounted with the positioning wheel 511, the axis of the positioning wheel 511 is parallel to the left-right direction, and the circumferential side of the positioning wheel 511 is provided with a wheel groove 5111 that cooperates with the through-length rib 3.

In this embodiment, in each positioning assembly 51, a plurality of support plates 512 are sequentially arranged in the transverse direction, and a positioning wheel 511 is provided on each support plate 512. In this way, during the threading process, the steel bar conveying mechanism can thread a plurality of through-length bars 3 at the same time, and a plurality of through-length bars 3 can be supported and guided by positioning wheels 511 at different transverse positions. Among them, the positioning wheel 511 has a wheel groove 5111, and the through-length bars 3 can move forward under the guidance of the wheel groove 5111. It can be ensured that a plurality of through-length bars 3 at different transverse positions have their own forward paths during the simultaneous threading process, and these through-length bars 3 will not be crowded together, thereby ensuring the smoothness of threading.

Optionally, referring to FIG. 2 and FIG. 4 , the positioning mechanism 5 further includes a transverse movement mechanism 53 , the transverse movement mechanism 53 is used to move relative to the base 4 along the left-right direction, and the lifting mechanism 52 is disposed on the transverse movement mechanism 53 ;

In each of the positioning mechanisms 5, some of the support plates 512 are provided with the positioning wheels 511 only at the first height or only at the second height, while other parts of the support plates 512 are provided with the positioning wheels 511 at both the first height and the second height; and in each of the positioning mechanisms 5, the axes of all the positioning wheels 511 are on the same vertical plane; wherein the first height and the second height are different height positions of the support plates 512, respectively.

In this embodiment, in each positioning mechanism 5, two kinds of positioning wheels 511 are installed on some of the support plates 512, and only one kind of positioning wheels 511 is installed on other parts of the support plates 512, and the axes of all the positioning wheels 511 are on the same vertical plane. As shown in FIG1, for example, from left to right, 11 support plates 512 are arranged in sequence, and the three leftmost support plates 512 and the three rearmost support plates 512 are all provided with positioning wheels 511 of one height (this height is recorded as the first height), the fourth support plate 512 on the left and the fifth support plate 512 on the left are provided with positioning wheels 511 of two heights (the first height and the second height, respectively), and the two middle support plates 512 are arranged with positioning wheels 511 at the second height, wherein the first height is higher than the second height. In this way, when the positioning assembly 51 in the positioning mechanism 5 rises from the height position shown in Figure 1 to the height position shown in Figure 6, the positioning wheel 511 at the first height can support and guide the upper layer of the through-length ribs 3, and the positioning wheel 511 at the second height can support and guide the lower layer of the through-length ribs 3, thereby ensuring that the upper layer of the through-length ribs 3 and the lower layer of the through-length ribs 3 can be threaded at the same time, and will not affect each other during the threading process.

In this embodiment, after the threading of the upper layer and multiple through-length bars 3 and the lower layer of multiple through-length bars 3 is completed, the front end of the through-length bar 3 has been supported and positioned by the front welding mechanism, while the rear end of the through-length bar 3 is supported and positioned by the steel bar pushing mechanism. Therefore, at this time, the positioning component 51 is no longer needed to support the through-length bar 3. Afterwards, as shown in Figure 7, the positioning component 51 can be driven downward by the lifting mechanism 52 for a certain distance to separate the wheel groove 5111 from the through-length bar 3. Then, as shown in Figure 8, the positioning component 51 can be moved horizontally for a certain distance by the transverse movement mechanism 53 to vertically stagger the through-length bar 3 and the positioning wheel 511. Afterwards, the positioning component 51 can be lowered to the initial position by the lifting mechanism 52 as shown in Figure 9. Finally, as shown in Figure 10, the positioning component 51 can be horizontally reset to the initial position by the transverse movement mechanism 53.

After threading the upper layer and multiple through-length ribs 3 and multiple through-length ribs 3 of the lower layer is completed, the positioning assembly 51 can be first moved downward by a certain distance through the second lifting unit 522 with a small stroke as shown in FIG7, so that the wheel groove 5111 is separated from the through-length rib 3, and then the positioning assembly 51 can be moved horizontally by a certain distance through the transverse mechanism 53 as shown in FIG8, so that the through-length rib 3 and the positioning wheel 511 are vertically staggered, and then the positioning assembly 51 can be lowered to the initial position by the first lifting unit 521 as shown in FIG9, and finally, the positioning assembly 51 can be horizontally reset to the initial position by the transverse mechanism 53 as shown in FIG10.
