Description

Technical Field

[0001] The utility model belongs to the technical field of steel bar skeleton forming, and particularly relates to an in-mold lifting table for the production of steel bar skeletons of highway precast box girders. Background Technique

[0002] The steel bar skeleton of the highway box girder is complex in structure. In the traditional production process, after the production of the previous parts is completed, the process of overall installation and forming can only be achieved through manual operation, resulting in low production efficiency and difficult quality guarantee.

[0003] The patent with the publication number CN116968171A discloses a box girder steel bar skeleton forming device, which realizes the automatic forming of the box girder steel bar skeleton through a stirrup suspension frame, a stirrup feeding bridge, a connection workstation, a conveying line and a longitudinal bar traction bridge, improving the production efficiency and reducing the amount of manual participation and labor intensity. However, after the production of the steel bar skeleton finished product is completed, it is necessary to transport the steel bar skeleton finished product to the tooling (i.e., the concrete pouring mold) of the next process, and this process is thus called "in-mold". In the traditional operation process, this action needs to be carried out by using the workshop overhead crane for hoisting. Due to the very poor stiffness of the steel bar skeleton, in order to ensure that no damage occurs during the hoisting process, multi-point hoisting needs to be adopted, which leads to a huge workload and a long time-consuming for the entire hoisting operation. If the conveying line of the above-mentioned published patent is used to transport the steel bar skeleton finished product, although hoisting can be avoided, due to the longitudinal bar traction bridge arranged at the end of the conveying line, due to the interference of the longitudinal bar traction bridge, the steel bar skeleton finished product cannot enter the mold through the conveying line.

[0004] In order to quickly transfer the steel bar skeleton finished product to the next process - in-mold, it is necessary to move the interfering equipment on the production line out of the conveying path to provide space for the movement of the finished product. Content of the Utility Model

[0006] The utility model proposes an in-mold lifting table for the production of steel bar skeletons of highway precast box girders.

[0007] The mold - entering lifting table includes: a jacking support frame, a lifting assembly, and a lifting longitudinal beam; the lifting assembly is installed on one side of the jacking support frame, the lifting assembly is connected to the lifting longitudinal beam and is used to drive the lifting longitudinal beam to lift; when the lifting longitudinal beam is at the first height, it is longitudinally butted with the traction longitudinal beam and is used to carry the finished - product traction mechanism moved out from the traction longitudinal beam.

[0008] Further, the lifting assembly includes: a lifting motor and a lifting transmission assembly; the lifting transmission assembly includes a meshing lifting gear and a lifting rack; the lifting motor is connected to the lifting longitudinal beam, and the output shaft of the lifting motor is connected to the lifting gear; the lifting rack is vertically installed on one side of the jacking support frame.

[0009] Further, the lifting assembly further includes a lifting guiding assembly; the lifting guiding assembly includes a lifting guide rail and a lifting slider; the lifting guide rail is vertically installed on one side of the jacking support frame, the lifting slider is in sliding fit with the lifting guide rail, and the lifting slider is connected to the lifting longitudinal beam.

[0010] Further, there are two groups of the lifting guiding assemblies, which are distributed on both sides of the lifting transmission assembly.

[0011] Further, there are two jacking support frames, which are distributed on both sides of the finished - product transportation line.

[0012] Further, the mold - entering lifting table further includes a strengthening cross - beam; both ends of the strengthening cross - beam are respectively connected to the lifting longitudinal beams on the two jacking support frames.

[0013] Further, support guide rails are respectively arranged on the traction longitudinal beam and the lifting longitudinal beam.

[0014] Further, a sensor is arranged on the lifting longitudinal beam.

[0015] Further, a limiting member is arranged at one end of the lifting longitudinal beam away from the traction longitudinal beam.

[0016] Further, the lifting stroke of the lifting longitudinal beam is more than twice the height from the top of the finished - product traction mechanism on the traction bridge to the ground.

[0017] The beneficial effects of the present utility model are as follows: By arranging an in-mold lifting table at the front end of the finished product feeding device, using the lifting assembly to lower the lifting longitudinal beam, enabling the lifting longitudinal beam to be docked with the traction longitudinal beam of the finished product feeding device, thereby transferring the finished product traction mechanism on the traction longitudinal beam to the lifting longitudinal beam, and then using the lifting assembly to lift the lifting longitudinal beam, it is possible to move the interfering equipment on the finished product conveying line out of the path of the finished product conveying line, enabling the reinforced concrete skeleton finished product to smoothly pass under the finished product traction mechanism and continue to move forward to the in-mold process.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] The following further describes the present utility model in detail in conjunction with the accompanying drawings and specific embodiments.

[0023] As Figures 1-3 shown, the in-mold lifting table for the production of the reinforced concrete skeleton of highway precast box girders is arranged at the front end of the finished product feeding device. As Figure 2 、 Figure 3As shown in the figure, the finished product feeding device includes a traction bridge 7, a finished product transportation line 9, and a finished product traction mechanism 8. The finished product traction mechanism 8 is located at the front end of the traction bridge 7. The in-mold lifting table is located at the front end of the finished product traction mechanism 8. The finished product transportation line 9 is used to carry the finished steel bar skeletons 10. The finished steel bar skeletons 10 are located at the rear end of the finished product traction mechanism 8. If the finished product transportation line 9 is continuously laid until it reaches the concrete pouring mold of the next process, the finished steel bar skeletons 10 can be transported into the concrete pouring mold by using the finished product transportation line 9, without the need for hoisting the finished steel bar skeletons 10. However, since the finished product traction mechanism 8 is located at the front end of the finished steel bar skeletons 10, the finished product traction mechanism 8 hinders the entry of the finished steel bar skeletons 10 into the concrete pouring mold. To solve this problem, the in-mold lifting table proposed by the present utility model is arranged at the front end of the finished product traction mechanism 8 to lift the finished product traction mechanism 8, facilitating the passage of the finished steel bar skeletons 10 under the finished product traction mechanism 8. After the finished steel bar skeletons 10 pass through, the finished product traction mechanism 8 is lowered to facilitate the production of the next box girder steel bar skeleton, realizing the continuous operation of the box girder steel bar skeleton production and improving the production efficiency.

[0024] On both sides of the finished product transportation line 9, there are traction bridges 7; the traction bridge 7 includes traction longitudinal beams 71; the finished product traction mechanism 8 is located above the finished product transportation line 9, and both ends of the finished product traction mechanism 8 are movably matched with the traction longitudinal beams 71 on both sides of the finished product transportation line 9; the finished product traction mechanism 8 includes a traction cross beam, a longitudinal bar clamping tooling, and traction drive components connected to both ends of the traction cross beam; the traction drive components at both ends of the traction cross beam are respectively connected to the two traction longitudinal beams 71, enabling the traction cross beam to move along the length direction of the traction longitudinal beams 71. A longitudinal bar clamping tooling is connected to the traction cross beam, and the longitudinal bar clamping tooling is used to clamp the longitudinal bars of the finished steel bar skeletons 10 or semi-finished steel bar skeletons on the finished product transportation line 9, and move the traction longitudinal bars on the finished product transportation line 9 to realize the movement of the finished steel bar skeletons 10 or semi-finished steel bar skeletons on the finished product transportation line 9.

[0025] As Figure 1 As shown in the figure, the in-mold lifting table of the present utility model includes: a jacking support frame 1, a lifting component 2, a lifting longitudinal beam 3, and a strengthening cross beam 4; the lifting component 2 is installed on one side of the jacking support frame 1, and the lifting component 2 is connected to the lifting longitudinal beam 3 for driving the lifting longitudinal beam 3 to lift and lower; when the lifting longitudinal beam 3 is at the first height, it is longitudinally butted with the traction longitudinal beam 71 for carrying the finished product traction mechanism 8 moved out from the traction longitudinal beam 71.

[0026] The lifting component 2 includes: a lifting motor 5, a lifting transmission component, and a lifting guiding component.

[0027] The lifting transmission component includes a meshing lifting gear and a lifting rack; the lifting motor 5 is connected to the lifting longitudinal beam 3, and the output shaft of the lifting motor 5 is connected to the lifting gear; the lifting rack is vertically installed on one side of the jacking support frame 1.

[0028] As Figure 1 shown, there are two sets of lifting guide components, distributed on both sides of the lifting transmission component. Each set of lifting guide components includes a lifting guide rail and a lifting slider; the lifting guide rail is vertically installed on one side of the jacking support frame 1, the lifting slider is slidably engaged with the lifting guide rail, and the lifting slider is connected to the lifting longitudinal beam 3.

[0029] The jacking support frame 1 is a frame structure, with the front and rear two side faces being trapezoidal and the inner side being rectangular, and the two lifting guide rails on each side are fixedly arranged on the two side columns on the inner side.

[0030] There are two jacking support frames 1, distributed on both sides of the finished product transportation line 9. The two ends of the strengthening cross beam 4 are respectively connected to the lifting longitudinal beams 3 on the two jacking support frames 1. There can be two strengthening cross beams 4, arranged at intervals along the length direction of the lifting longitudinal beam 3. The two strengthening cross beams 4 and the two lifting longitudinal beams 3 are connected as a whole. The distance between the two lifting longitudinal beams 3 is the same as the distance between the two traction longitudinal beams 71. The two lifting longitudinal beams 3 and the two traction longitudinal beams 71 are respectively butted, so that the finished product traction mechanism 8 on the traction longitudinal beam 71 can smoothly transition to the lifting longitudinal beam 3.

[0031] Support guide rails are respectively arranged on the traction longitudinal beam 71 and the lifting longitudinal beam 3. The traction drive component of the finished product traction mechanism 8 cooperates with the support guide rail, so that the finished product traction mechanism 8 moves along the support guide rail.

[0032] A sensor 6 is arranged on the lifting longitudinal beam 3. It is used to detect the position of the finished product traction mechanism 8 on the lifting longitudinal beam 3 and the lifting height.

[0033] A limiting member is arranged at one end of the lifting longitudinal beam 3 away from the traction longitudinal beam 71. Thus, it is avoided that the finished product traction mechanism 8 disengages from the end of the lifting longitudinal beam 3 away from the traction longitudinal beam 71.

[0034] The lifting stroke of the lifting longitudinal beam 3 is more than twice the height from the top of the finished product traction mechanism 8 on the traction bridge 7 to the ground. For example, if the height from the top of the finished product traction mechanism 8 on the traction bridge 7 to the ground is h, then the lifting stroke of the lifting longitudinal beam 3 is at least 2h. The lifting longitudinal beam 3 is lifted high enough to ensure that the finished product of the steel bar skeleton 10 can smoothly pass under the finished product traction mechanism 8.

[0035] The working process of the mold - entering lifting table for the production of highway precast box - girder steel bar skeletons in this embodiment includes the following steps:

[0036] S1. In the initial state, the lifting longitudinal beam 3 is at the high position of the lifting component 2;

[0037] S2. After obtaining the lifting signal, the lifting vertical beam 3 descends to the same height as the traction vertical beam 71 of the traction bridge frame 7. At this time, the lifting vertical beam 3 is completely docked with the traction vertical beam 71;

[0038] S3. The finished product traction mechanism 8 originally located on the traction vertical beam 71 moves forward to the lifting vertical beam 3 of the mold loading and unloading lifting table, and the precise position of the finished product traction mechanism 8 on the lifting vertical beam 3 is ensured by the sensor 6;

[0039] S4. After the finished product traction mechanism 8 stops moving and remains stable in position, the lifting motor 5 is started, and the finished product traction mechanism 8 is lifted by the lifting assembly 2. The lifting height is controlled by the sensor 6 and kept stable, so as to create enough horizontal passing space for the steel bar framework finished product 10 below;

[0040] S5. The finished product conveyor line conveys the steel bar framework finished product 10 forward, so that the steel bar framework finished product 10 passes under the finished product traction mechanism 8 and continues to move forward to the next working station for mold loading;

[0041] S6. After the steel bar framework finished product 10 below completely passes, the lifting vertical beam 3 descends along the lifting assembly 2 to a position equal in height to the traction vertical beam 71 of the traction bridge frame 7, and the finished product traction mechanism 8 moves backward to the traction vertical beam 71 to complete the operation of this stage.

[0042] The above is only the preferred implementation mode of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions falling within the idea of the present invention belong to the protection scope of the present invention. It should be pointed out that for those of ordinary skill in the art, several improvements and refinements made without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
