[0030] As an emerging construction product, prestressed concrete precast beams are widely used in the construction of various large factories, logistics warehouses, production workshops and large-span and large-bay buildings.

[0031] In the process of manufacturing precast beams, an output mechanism is usually used to adjust the side formwork in order to manufacture precast beams of different sizes. However, the existing output mechanism is not designed reasonably and cannot effectively adjust the spacing of the side formwork.

[0032] Based on the above problems, an embodiment of the utility model provides a precast beam mold, which is applied to the technical field of building production equipment, and is particularly suitable for prestressed concrete precast beams.

[0033] See also Figure 1 The precast beam mold 1 includes a bidirectional turbine contraction mechanism 10, a side mold mechanism 20, a mold platform 30, a base 40, an end mold and a cushion block 50, wherein there are multiple bases 40, and the multiple bases 40 are arranged in parallel on the mold platform 30; there are multiple cushion blocks 50, and the multiple cushion blocks 50 are detachably installed on the base 40, and the multiple cushion blocks 50 are used to support the side mold mechanism 20 together; the side mold mechanism 20 includes two side mold plates, and the bidirectional turbine contraction mechanism 10 is arranged between the two side mold plates to adjust the distance between the two side mold plates.

[0034] In this embodiment, the number of side mold mechanisms 20 is also multiple, and one side mold mechanism 20 is arranged between two adjacent bases 40, and the side mold mechanism 20 is placed on the cushion block 50. Therefore, by setting cushion blocks 50 of different heights, the height of the side mold mechanism 20 relative to the mold platform 30 can be adjusted, so as to produce beams of different heights, thereby improving the adaptability of the precast beam mold 1; and the two adjacent side molds and the end mold are used together to produce the precast beam.

[0035] For further information, see Figures 2 to 4 The bidirectional turbine contraction mechanism 10 includes a turbine reducer 100 , an input shaft 200 and two output shafts 300 .

[0036] Among them, the input shaft 200 is transmission-connected to the turbine reducer 100, and the two output shafts 300 are respectively connected to the two ends of the turbine reducer 100, and the two output shafts 300 are also used to connect to the side formwork of the precast beam; the input shaft 200 is used to drive the two output shafts 300 to move relative or opposite to each other through the turbine reducer 100 under the action of driving force.

[0037] In this embodiment, the input shaft 200 rotates axially under the action of an external driving force, and drives the two output shafts 300 to move synchronously toward or away from each other in the directions of the two ends of the turbine reducer 100 through the turbine reducer 100, thereby driving the side templates connected to the two output shafts 300 to move toward or away from each other, thereby adjusting the spacing between the two side templates to adapt to the production of prefabricated beams of different sizes; it can be seen that the bidirectional turbine contraction mechanism 10 has a simple structure, reasonable design, and good transmission effect, and can effectively drive the movement of the side templates through the two output shafts 300.

[0038] Furthermore, the axes of the two output shafts 300 are arranged in parallel, so that the two output shafts 300 are arranged in a staggered manner.

[0039] In this embodiment, the two output shafts 300 are located in the same horizontal plane and are arranged in parallel, and the two output shafts 300 are respectively located on both sides of the input shaft 200, so that the two output shafts 300 are staggered in the horizontal plane direction, that is, the two output shafts 300 are not located on the same axis; with this arrangement, the structural design of the bidirectional turbine contraction mechanism 10 can be made more reasonable.

[0040] Furthermore, the two output shafts 300 are both threadedly connected to the turbine reducer 100 , and the threads of the two output shafts 300 have opposite rotation directions.

[0041] In this embodiment, precisely because the threads of the two output shafts 300 have opposite rotation directions, when the external driving force drives the input shaft 200 to rotate, the two output shafts 300 are driven to move in opposite directions through the turbine reducer 100, that is, the two output shafts 300 are driven to move toward or away from each other, thereby driving the side templates connected thereto to move toward or away from each other through the two output shafts 300, thereby achieving the purpose of adjusting the spacing between the side templates.

[0042] Furthermore, the bidirectional turbine contraction mechanism 10 also includes a driving handle 400 , which is connected to the input shaft 200 .

[0043] In this embodiment, the operator manually rotates the driving handle 400 to drive the input shaft 200 to rotate, and thereby drives the two output shafts 300 to move through the turbine reducer 100, and finally the two output shafts 300 drive the two side templates to move toward or away from each other, thereby achieving the purpose of adjusting the distance between the two side templates.

[0044] It is worth mentioning that the driving handle 400 is detachably connected to the input shaft 200, thereby facilitating the installation or removal of the driving handle 400.

[0045] Furthermore, a clamping portion 210 is provided at the end of the input shaft 200 , and a clamping slot adapted to the clamping portion 210 is provided on the driving handle 400 , and the clamping portion 210 is clamped and matched with the clamping slot.

[0046] In this embodiment, by engaging the clamping groove of the driving handle 400 with the clamping portion 210 of the input shaft 200, when the driving handle 400 is connected to the input shaft 200, it is ensured that the input shaft 200 can rotate synchronously with the driving handle 400, thereby avoiding relative sliding of the driving handle 400 and the input shaft 200.

[0047] Furthermore, there are multiple turbine reducers 100 , and the multiple turbine reducers 100 are coaxially arranged through the input shaft 200 , and each turbine reducer 100 is connected to two output shafts 300 .

[0048] In this embodiment, a plurality of turbine reducers 100 are provided, and each turbine reducer 100 is connected to two output shafts 300, so that the output shafts 300 of the plurality of turbine reducers 100 act together on the side formwork, thereby making the side formwork move faster.

[0049] Specifically, the number of the turbine reducers 100 is two; of course, in other embodiments, the number of the turbine reducers 100 can also be other settings, which are not specifically limited here.

[0050] Furthermore, the bidirectional turbine retraction mechanism 10 also includes a fastening rod 500 , which is used to be connected to the side template, and the multiple output shafts 300 located on the same side of the multiple turbine reducers 100 are all connected to the fastening rod 500 .

[0051] In this embodiment, a fastening rod 500 is provided for connecting to the side formwork, and multiple output shafts 300 on the same side of multiple turbine reducers 100 are connected to the same fastening rod 500, so that the output shafts 300 of the multiple turbine reducers 100 can act on the side formwork more stably.

[0052] Furthermore, the bidirectional turbine contraction mechanism 10 also includes a rod sleeve 600 , which is used to be arranged on the side template, and the rod sleeve 600 is also sleeved outside the fastening rod 500 .

[0053] In this embodiment, the rod sleeve 600 is sleeved on the outside of the fastening rod 500 and vertically attached to the reinforcing rib of the side template, and the output shaft 300 is connected to the fastening rod 500, so that the force of the output shaft 300 is stably transmitted to the side plate through the fastening rod 500 and the rod sleeve 600.

[0054] In detail, there are multiple rod sleeves 600 , which are arranged at intervals and are collectively sleeved outside the fastening rod 500 .

[0055] In this embodiment, the number of the insertion rod sleeves 600 is two; of course, in other embodiments, the number of the insertion rod sleeves 600 can also be other settings, which is not specifically limited here.

[0056] In summary, the utility model provides a bidirectional turbine contraction mechanism 10 and a prefabricated beam mold 1, in which the input shaft 200 rotates axially under the action of an external driving force, and drives the two output shafts 300 to move synchronously toward or away from each other in the directions of the two ends of the turbine reducer 100 through the turbine reducer 100, thereby driving the side templates connected to the two output shafts 300 to move toward or away from each other, thereby adjusting the spacing between the two side templates to adapt to the production of prefabricated beams of different sizes; it can be seen that the bidirectional turbine contraction mechanism 10 has a simple structure, a reasonable design, and a good transmission effect, and can effectively drive the movement of the side templates through the two output shafts 300.
