Description

Technical Field

[0001] The utility model relates to the technical field of concrete prefabricated block production, in particular to a concrete prefabricated block forming device. Background Art

[0002] Concrete is a general term for composite materials that are made of gel material, aggregate and water in appropriate proportions and then hardened after a certain period of time. It is the world's most widely used artificial civil construction material. Concrete has high hardness, a wide range of raw materials and low cost. It is widely used in structures such as houses, roads, military projects, and nuclear power plants. During the construction process, the required concrete size for some construction locations has been determined. In order to save the time required for construction, it is necessary to customize concrete precast blocks that are suitable for this size in advance, so that they can be used directly, saving concrete casting time and thus reducing the construction period. When making concrete precast blocks, concrete needs to be poured into the concrete precast block mold. After it is cooled and formed, it becomes a concrete precast block. When making and processing concrete precast blocks, a concrete precast block forming device is required.

[0003] When the molding device in the prior art is producing and processing the precast concrete blocks, it is impossible to effectively change the specifications of the mold according to actual needs. Since the mold in the prior art is generally fixed on a turntable, a molding device of one specification can only produce one specification of precast concrete blocks, and cannot produce precast concrete blocks of different specifications according to actual needs. When it is necessary to produce precast concrete blocks of different specifications, molding devices of different specifications need to be used, which will increase the production cost of the producer and reduce the practicality of the molding device. Moreover, the molding device in the prior art cannot effectively stir the concrete raw materials inside the storage tank, which will cause the concrete to solidify in the storage tank for a long time, thereby affecting the normal use effect of the concrete.

[0004] Compared with the Chinese patent with publication number CN220146261U, the utility model discloses a prefabricated concrete block forming device, belongs to the technical field of production of prefabricated concrete block forming devices, and aims at the problems of low preparation efficiency of prefabricated concrete block forming devices and easy leakage of artificial concrete pouring, including a turntable, a sleeve is fixed on the inner side of the turntable, the sleeve is rotatably connected to the inner side of the opening through a bearing, a gear ring is fixed on the outer bottom of the sleeve, a support rod is penetrated and rotatably connected to the middle of the sleeve, the support rod is fixed to the middle of the top wall of the fixed plate, and a driving motor is fixed on the right side of the top wall of the fixed plate; the utility model rotates a toggle plate during the rotation of the sleeve, stops rotating after the toggle plate moves to the upper side of the control button, and the toggle plate and the toggle groove cooperate to continuously press the control button, thereby opening the solenoid valve through the control button, so that concrete is poured from the inside of the storage box through the pouring pipe into the corresponding pouring mold, and the concrete prefabricated block prefabricated forming device is automatically poured, and the preparation efficiency of the concrete prefabricated block prefabricated forming device is further improved.

[0005] The above scheme can very conveniently pour concrete into the pouring mold, thereby achieving the purpose of automatic pouring of concrete precast blocks, and further effectively improving the preparation efficiency of concrete precast blocks. However, the mold and the turntable in the above scheme are still fixed, and the specifications of the mold cannot be replaced according to actual needs. Moreover, the above scheme cannot effectively stir the concrete inside the storage tank, and fails to solve the problems raised in the above background technology. Utility Model Content

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] See also Figure 1 - Figure 5 As shown, this embodiment provides a concrete prefabricated block forming device, including a chassis 1, and also including:

[0028] The turntable 2 is located above the chassis 1. The upper surface of the turntable 2 is fixedly connected with a fixing column 3. The top of the fixing column 3 is fixedly connected with a storage tank 5 through a support frame 4. The bottom of the storage tank 5 is connected with a bellows 11 through a solenoid valve 10. The interior of the support frame 4 is provided with a fixing groove for fixing the bellows 11.

[0029] A plurality of molds 6 are located above the turntable 2;

[0030] A driving assembly is arranged on the upper surface of the chassis 1 and is used to drive the turntable 2 to rotate synchronously;

[0031] Replacement components are arranged at equal intervals on the upper surface of the turntable 2 and are used to replace the specifications and dimensions of the mold 6;

[0032] The stirring assembly is arranged inside the storage tank 5 and is used to stir the concrete inside the storage tank 5 .

[0033] The above working principle: when it is necessary to make and process the concrete prefabricated block, it is only necessary to add the concrete into the storage tank 5 first, at which time the stirring assembly starts to operate, and the stirring assembly can effectively stir the concrete inside the storage tank 5, thereby preventing the concrete from solidifying and affecting normal use, and then the mold 6 is fixedly installed above the turntable 2 by replacing the assembly, at which time the solenoid valve 10 is opened, and the concrete inside the storage tank 5 is transmitted to the mold 6 through the bellows 11, thereby achieving the purpose of making the concrete prefabricated block, when it is necessary to transfer the concrete to other molds 6, the driving assembly starts to operate, driving the turntable 2 to rotate synchronously, and the turntable 2 drives the mold 6 to move synchronously, at which time the other molds 6 can be moved to the bottom of the bellows 11, so that the concrete can be transferred to the other molds 6 for making and processing the concrete prefabricated block, effectively improving the production efficiency of the concrete prefabricated block, and when it is necessary to replace the specifications of the mold 6, it is also only necessary to replace the components to conveniently replace the specifications of the mold 6, saving time and effort.

[0034] In order to effectively drive the turntable 2 to rotate, so that the turntable 2 can drive the mold 6 to move synchronously, the driving assembly includes a driving box 24 fixedly connected to the upper surface of the chassis 1, and a first motor 25 is fixedly connected to one side of the driving box 24. The output shaft of the first motor 25 is fixedly connected to a driving rod 26 through a coupling, and the other end of the driving rod 26 is fixedly connected to a first bevel gear 27. The inner bottom end of the driving box 24 is rotatably connected to a rotating rod 29, and the outer side of the rotating rod 29 is fixedly connected to a second bevel gear 28 meshing with the first bevel gear 27. The top of the rotating rod 29 is fixedly connected to the bottom of the turntable 2. When it is necessary to drive the turntable 2 to rotate, the first motor 25 starts to run, driving the driving rod 26 to rotate synchronously, the driving rod 26 drives the first bevel gear 27 to rotate synchronously, the first bevel gear 27 drives the second bevel gear 28 to rotate synchronously, and the second bevel gear 28 drives the rotating rod 29 to rotate synchronously, and the rotating rod 29 drives the turntable 2 to rotate synchronously. At this time, the turntable 2 can be rotated, so that the turntable 2 can effectively drive the mold 6 to move synchronously.

[0035] Taking into account the need to improve the stability of the turntable 2 during rotation, a plurality of support rods 30 are fixedly connected to the bottom of the turntable 2, and the bottom ends of the plurality of support rods 30 are fixedly connected to movable wheels 31. The upper surface of the chassis 1 is provided with guide grooves for the movable wheels 31 to move. During the rotation of the turntable 2, the support rods 30 will be driven to move synchronously, and the support rods 30 will then drive the movable wheels 31 to move synchronously. At this time, the movable wheels 31 can effectively improve the smoothness of the turntable 2 during rotation. At the same time, the support rods 30 can play a certain supporting role on the turntable 2, thereby effectively improving the stability of the turntable 2 during rotation.

[0036] In order to effectively fix the mold 6 on the top of the turntable 2, the replacement component includes a connecting block 13 arranged at equal intervals on the upper surface of the turntable 2, and the upper surface of the connecting block 13 is symmetrically provided with a storage groove 14, and the inner wall of the storage groove 14 is symmetrically provided with a first telescopic rod 15, and the telescopic ends of the plurality of first telescopic rods 15 are fixedly connected with a plug-in rod 16, and the outer sides of the plurality of first telescopic rods 15 are sleeved with a return spring 17, and the plurality of return springs 17 are in contact between the plug-in rod 16 and the storage groove 14. The bottom of the mold 6 is fixedly connected with a mounting frame 12, and the bottom of the mounting frame 12 is fixedly connected with a plug-in block 32. The upper surface of the connecting block 13 is provided with a guide groove for the plug-in block 32 to move. The outer sides of the mounting frame 12 and the connecting block 13 are provided with a guide groove for the plug-in rod 16 to move. When the mold 6 needs to be fixedly installed on the top of the turntable 2, it is only necessary to first align the mold 6, and the mold 6 can be fixedly installed on the top of the turntable 2. The plug-in rod 16 is pressed, and the plug-in rod 16 will squeeze the first telescopic rod 15 and the return spring 17 synchronously, and then the installation frame 12 is sleeved on the outside of the connecting block 13. When the plug-in rod 16 moves to the guide groove outside the installation frame 12, the return spring 17 is reset, driving the plug-in rod 16 to reset and move synchronously. When the plug-in rod 16 is inserted into the guide groove outside the installation frame 12, the installation frame 12 and the connecting block 13 can be fixed. At this time, the mold 6 can be fixedly installed above the turntable 2, so as to facilitate the use of the mold 6. When the installation frame 12 is sleeved on the outside of the connecting block 13, the installation frame 12 will drive the plug-in block 32 to move synchronously. When the plug-in block 32 is inserted into the guide groove on the upper surface of the connecting block 13, the stability of the installation between the installation frame 12 and the connecting block 13 can be further improved.

[0037] In order to conveniently disassemble the installation frame 12 and the connecting block 13, so as to facilitate the staff to replace the specifications of the mold 6, fixed plates 18 are symmetrically provided on both sides of the outer walls of the multiple connecting blocks 13, and guide grooves for the movement of the connecting rods 19 are opened inside the multiple fixing plates 18. One end of the multiple connecting rods 19 is fixedly connected to the limiting disk 20, and the other ends of each two connecting rods 19 are fixedly connected to the pressing plate 22. The outsides of the multiple connecting rods 19 are sleeved with resistance springs 21, and the multiple resistance springs 21 are in contact between the pressing plate 22 and the fixed plate 18. The opposite side of each two pressing plates 22 is symmetrically provided with a movable rod 23 for squeezing the plug-in rod 16. The bottom of the installation frame 12 is opened. A movable groove is provided for the movement of the fixing plate 18. When the installation frame 12 and the connecting block 13 need to be disassembled, it is only necessary to press the pressing plate 22 first. At this time, the pressing plate 22 will drive the movable rod 23 to move synchronously. When the movable rod 23 squeezes the plug-in rod 16 into the guide groove that is separated from the outside of the installation frame 12, the installation frame 12 can be pulled out from the outside of the connecting block 13. At this time, the mold 6 can be disassembled. During the movement of the pressing plate 22, the connecting rod 19 will also be driven to move synchronously. At this time, the resistance spring 21 will be squeezed. When the mold 6 is disassembled, the pressing plate 22 is released. At this time, the resistance spring 21 is reset, which can effectively drive the pressing plate 22 to reset and move synchronously.

At this time, the concrete inside the storage tank 5 can be stirred by the stirring frame 9, thereby preventing the concrete from solidifying and affecting normal use.
