Description

Technical Field

[0001] The invention relates to the technical field of steel column placement and loading, and in particular to a steel column continuous loading device. Background Art

[0002] At present, before the concrete is poured externally, the steel columns are uniformly stacked in the placement area. The stacking method is simple stacking, and the steel columns of adjacent layers are placed in layers by setting up wooden strips. Then, when pouring, the steel columns need to be lifted to the pouring area by lifting equipment for external pouring. In this way, when performing the operation, not only do they need to be hoisted to the stacking area for stacking layer by layer, but they also need to be hoisted to the pouring area again when pouring. This is not only laborious but also time-consuming. For this reason, we have designed a stacking and loading mechanism.

[0051] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. Obviously, the embodiments described are only some embodiments of the invention, not all embodiments. In the absence of conflict, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of the invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the invention.

[0052] See also Figures 1 to 6The present invention discloses a continuous feeding device for steel columns, comprising: a feeding rack 1, which is provided with three layers for placing the main body of the steel column, and a conveyor belt 2 is provided on each layer of the feeding rack 1, for loading the main body of the steel column from one side of the uppermost end of the feeding rack 1, and then unloading it from the other side of the lowermost end, so that the steel column is conveyed and placed from one side of the feeding rack 1 in a folded shape, and then continuously fed to the casting operation area from the other side;

[0053] Two groups of cross-layer conveying units 3 are respectively arranged between the side of the top conveyor belt 2 away from the loading side and the middle conveyor belt 2, and between the side of the middle conveyor belt 2 close to the loading side and the bottom conveyor belt 2, for realizing the conveying of the steel column body on the conveyor belts 2 of different layers.

[0054] Wherein, the cross-layer transport unit 3 includes:

[0055] A lifting plate 31 is provided between the conveyor belts 2 of two adjacent layers and is used to lift the steel column body of the upper layer to the lower layer;

[0056] A power assembly 32 is provided on the lifting plate 31 and is used to drive the lifting plate 31 to move up and down;

[0057] A grabbing assembly 33 is provided on the lifting plate 31 and is used to grab the steel column body on the conveyor belt 2 close to the lifting plate 31 and place it on the lifting plate 31;

[0058] The cooperative component 34 is arranged between the lifting plate 31 and the conveyor belt 2. When the power component 32 drives the lifting plate 31 to descend, it is used to synchronously drive the conveyor belt 2 to move an end distance, so that the steel column body on the conveyor belt 2 close to the grasped steel column body moves to the position of the grasped steel column body.

[0059] In addition, the power assembly 32 includes:

[0060] First threaded rods 321 are symmetrically arranged on both sides of the lifting plate 31, and the first threaded rods 321 are threadedly connected to the lifting plate 31;

[0061] A first motor 322 is used to drive the first threaded rod 321 to rotate, and the first motor 322 is fixedly disposed on the loading rack 1.

[0062] At the same time, the grabbing component 33 includes:

[0063] A grab bar 331 is slidably provided on one side of the lifting plate 31 , and a sliding groove 333 is provided on the lifting plate 31 for limiting the sliding of the grab bar 331 ;

[0064] a second threaded rod 332 threadedly connected to the grab bar 331;

[0065] A second motor 334 fixedly mounted on the lifting plate 31 is configured to drive the second threaded rod 332 to rotate;

[0066] An electric retractable plate 335 is provided at the end of the grab bar 331 away from the second motor 334;

[0067] When performing the grabbing action, the second motor 334 will drive the second threaded rod 332 to rotate, so that the grabbing bar 331 moves toward the side of the conveyor belt 2 to the position of the steel column body, and then the electric telescopic plate 335 extends to form an L shape with the grabbing bar 331, and then the second motor 334 drives the grabbing bar 331 to move back, thereby pulling the steel column body back to the lifting plate 31, and then the electric telescopic plate 335 is reset to complete a grabbing action.

[0068] At the same time, the conveyor belt 2 is configured as a chain-type transmission belt, and the rotating shaft 21 of the chain-type transmission belt close to the lifting plate 31 extends to the outside of the chain-type transmission belt and is provided with a gear assembly 4. The cooperative assembly 34 is connected to the gear assembly 4 and is used to drive the gear assembly 4 to rotate in one direction.

[0069] Wherein, the gear assembly 4 includes:

[0070] a rotating gear 41 provided at the extended end of the rotating shaft 21;

[0071] The one-way limiting member 42 provided between the rotating gear 41 and the extended end portion of the rotating shaft 21 is used for the rotating gear 41 to drive the rotating shaft 21 to rotate when the rotating gear 41 rotates in the forward direction, and prevent the rotating shaft 21 from rotating when the rotating gear 41 rotates in the reverse direction.

[0072] In addition, the coordination component 34 includes:

[0073] A pulley 341, one end of which is meshed and sleeved on the rotating gear 41, and a driven gear 342 for meshing and sleeved on the other end of the pulley 341 is provided on the loading rack 1, and an external gear 343 is provided on the outside of the pulley 341;

[0074] The rack 344 is disposed on a side of the lifting plate 31 close to the pulley 341 , and the rack 344 is engaged with the external gear 343 of the pulley 341 .

[0075] At the same time, the one-way limiting member 42 includes:

[0076] A rotating disk 421 is coaxially fixedly arranged at the extended end of the rotating shaft 21. A plurality of limiting grooves 422 are arranged in a circular array on the rotating disk 421. A clamping strip 423 is rotatably arranged in the limiting groove 422.

[0077] The rotating gear 41 is sleeved on the outside of the rotating disk 421 and is coaxially arranged with the rotating disk 421. The sleeve connection between the rotating gear 41 and the rotating disk 421 is provided with abutment grooves 424 for abutting the plurality of the clamping strips 423.

[0078] When the lifting plate 31 moves downward, the outer gear 343 of the rack 344 and the pulley 341 engages, which can pull the pulley 341 to rotate, thereby driving the rotating gear 41 as shown in FIG. Figure 5 As shown, the conveyor belt 2 rotates in the forward direction, thereby driving the rotating shaft 21 of the conveyor belt 2 to rotate through the setting of the one-way limiter 42, so that the conveyor belt 2 rotates back one end distance when the telescopic plate descends, so that the steel column body moves to the position of the steel column body that was previously captured by the capture assembly 33;

[0079] When the lifting plate 31 moves upward, the clip 423 in the one-way limiter 42 is not abutted by the abutment groove 424. Therefore, when the rotating gear 41 rotates in the reverse direction, it will not drive the rotating disk 421 to rotate, so that the conveyor belt 2 will not rotate. The lifting plate 31 will only drive the upper conveyor belt 2 to move when the steel column body reaches the next conveyor belt 2 during downward transportation, thereby realizing continuous one-way transportation of the conveyor belt 2.

[0080] Among them, the conveyor belt 2 on the top layer is provided with an adjustment unit 5 for adjusting the lateral position of the steel column body when the steel column body is hoisted onto the conveyor belt 2.

[0081] Finally, the adjustment unit 5 comprises:

[0082] A plurality of stop plates 51 are evenly distributed on the conveyor belt 2;

[0083] An adjusting member 52 provided on the side of the conveyor belt 2 and cooperating with the stop plate 51 for adjustment:

[0084] Wherein, the adjusting member 52 includes:

[0085] A fixed plate 521 is fixedly arranged on the outer side of the conveyor belt 2;

[0086] an adjusting plate 522, wherein the adjusting plate 522 is rotatably arranged on the conveyor belt 2 in a direction perpendicular to the transport direction of the conveyor belt 2;

[0087] a third motor 523 fixedly mounted on the fixing plate 521 and configured to drive the adjusting plate 522 to rotate;

[0088] The push plate 524 is slidably disposed on the fixed plate 521;

[0089] The electric telescopic rod 525 is provided on the fixed plate 521 and is used to push the push plate 524 to slide;

[0090] When the cooperative component 34 in the cross-layer conveying unit 3 moves once through the power component 32, it can drive the conveyor belt 2 to move a certain distance. During one movement of the conveyor belt 2, after the upper steel column body moves away from the position of the adjusting plate 522, the third motor 523 will drive the adjusting plate 522 to rotate 90 degrees to just above the conveyor belt 2, so that the distance between the stop plate 51 and the adjusting plate 522 is the length of one movement of the conveyor belt 2. Then, after the conveyor belt 2 finishes moving, due to the limiting effect of the stop plate 51 and the adjusting plate 522, the steel column body will be clamped after being moved, so that the steel column body will be adjusted to a parallel state because it is not necessarily in a parallel state after lifting. Then, the push plate 524 will push the middle part under the action of the electric telescopic rod 525, thereby pushing the steel column body onto the conveyor belt 2, so that the steel column body will be vertically and symmetrically arranged with the conveyor belt 2, thereby completing the calibration of its position, and then the adjusting plate 522 and the push plate 524 will be reset, and move again with the next movement of the power component 32.

[0091] It should be noted that if the embodiments of the invention involve directional indications (such as up and down), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0092] In addition, the meaning of "and / or" appearing in the full text includes three parallel schemes. Taking "A and / or B" as an example, it includes scheme A, scheme B, or schemes in which A and B are satisfied at the same time. In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the invention, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one such feature. In addition, "multiple" refers to more than two. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to implement them. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the invention.
