Description

Technical Field

[0002] Precast concrete components are building components that are prefabricated in factories using concrete as the basic material, including beams, slabs, columns, and building decoration accessories. The production of precast concrete components is usually achieved by pouring concrete in a mold. In the prior art, during the processing and production process of precast concrete components, the mixed concrete material is often poured into a precast mold, and the mold is shaken to evenly fill the concrete material into the mold, and the excess material on the top of the mold is cleaned and then transferred.

[0003] The production of assembled precast concrete components is to manufacture precast concrete components inside a mold box. The precast concrete components after molding need to be demoulded. Most of the existing technologies flip the entire device to make the precast concrete components after molding separate from the mold box. The degree of demoulding automation is low, which consumes a lot of manpower and time. At the same time, demoulding only relies on the dead weight of the precast concrete parts, and the demoulding effect is poor.

[0040] Pulleys 18 matching the first belt 7 and the second belt 8 are fixed to the ends of each first rotating shaft 5 and the second rotating shaft 6 respectively; conveying wheels 19 matching the conveyor belt 12 are fixed to the circumferential sides of the two connecting shafts 11; a driving motor is fixedly installed on the side of the L-shaped baffle 4; the output end of the driving motor is fixedly connected to a connecting shaft 11 through a reducer; sprockets 20 are fixed on a second rotating shaft 6 and an adjacent connecting shaft 11; a chain is provided for meshing transmission between the two sprockets 20; a linkage gear 21 that meshes with each other is fixed to a first rotating shaft 5 and its adjacent second rotating shaft 6; a connecting rod 76 is fixedly connected between the two second rotating shafts 6 near the conveyor belt 12.

[0041] Working principle of the first embodiment:

[0042] By placing each group of mold boxes 2 with concrete precast components 3 cast on the conveyor belt 12, the slide groove 13 at the bottom of the tool box 2 is placed in the guide belt 14, and the concrete precast components in each group of mold boxes 2 are left to stand or dried and formed by an external drying device. After the concrete precast components 3 are formed, the driving motor is started by the controller to drive the corresponding connecting shaft 11 to rotate, thereby driving the conveyor belt 12 to transmit through the conveyor wheel 19. In this process, the corresponding sprocket wheel 20 is driven to rotate, and the corresponding second rotating shaft 6 is driven to rotate through the chain transmission, thereby driving the corresponding second belt 8 through the corresponding pulley 18, and the corresponding first belt 7 and the adjacent second belt 8 are driven to rotate synchronously in the opposite direction through the meshing cooperation of the two sets of linkage gears 21.

[0043] The conveyor belt 12 is driven synchronously with each group of first belts 7 and second belts 8, and each group of mold boxes 2 placed on the conveyor belt 12 is conveyed. The fixed rod 15 on the outermost mold box 2 near the L-shaped baffle 4 is conveyed to between the first belt 7 and the adjacent second belt 8 and is blocked. When the first belt 7 and the adjacent second belt 8 rotate synchronously in the opposite direction until the two avoidance grooves 9 gradually approach the corresponding fixed rod 15, the fixed rod 15 moves into the rotating hole. Thereafter, the fixed rod 15 is conveyed synchronously with the first belt 7 and the second belt 8 that rotates synchronously in the opposite direction.

[0044] During the transportation of the mold box 2, the corresponding mold box 2 is flipped and the flipped mold box 2 is knocked through the linkage with the guide device 17, so as to complete the automatic demoulding of the mold box 2 and the precast concrete component 3. A transmission belt for conveying the precast concrete component 3 is arranged between the two L-shaped baffles 4 and below the corresponding mold box 2. A transmission belt for conveying the mold box 2 is arranged at the ends of the two L-shaped baffles 4 away from the extension plate 10, so as to realize the classified transportation of the mold box 2 and the precast concrete component 3 after demoulding.

[0046] The sliding portion 30 includes a tooth plate 31 meshing with the driving gear 16; a sliding sleeve 32 slidingly matched with the square rod 28 is fixed to the bottom surface of the tooth plate 31; a sliding cavity 33 cooperating with the sliding rod 29 is provided at the end of the tooth plate 31; a return spring 34 is fixedly connected between the end of the sliding rod 29 and the sliding cavity 33; a baffle 35 is fixed to the side of the square rod 28; a guide groove 36 is provided on the side of the tooth plate 31; a retaining frame 37 is slidably arranged on the inner wall of the guide groove 36; a lifting portion 38 adapted to the upper straight guide plate 23, the lower straight guide plate 24 and the first inclined guide plate 25 is slidably arranged on the surface of the retaining frame 37.

[0047] Ear seats 39 are fixed at both ends of the tooth plate 31; a first pressure sensor 40 and a second pressure sensor 41 are fixedly installed on the side of the baffle 35 and the side of an ear seat 39 respectively; a T-shaped plate 42 is fixed on the side of the sliding sleeve 32; a plug rod 43 is slidably arranged through the side of the T-shaped plate 42; a socket 44 for plugging with the plug rod 43 is opened on the side of the square rod 28; a stopper 45 is fixed at the end of the T-shaped plate 42; an electromagnetic coil 46 is fixedly installed on the side of the stopper 45; an armature column 47 is fixed at the end of the plug rod 43; an extrusion spring 48 is fixed between the stopper 45 and the end of the plug rod 43; a controller is fixedly installed on the side of the L-shaped baffle 4; the input end of the controller is electrically connected to the first pressure sensor 40 and the second pressure sensor 41 respectively, and its output end is electrically connected to the drive motor and the electromagnetic coil 46 respectively.

[0048] A guide rod 49 is fixed between the inner walls of the guide groove 36; the retaining frame 37 includes a guide plate 50 slidably arranged in the guide groove 36; a guide hole 51 slidably matched with the guide rod 49 is opened on the side of the guide plate 50; a connecting spring 52 sleeved on the guide rod 49 is fixedly connected between the side of the guide plate 50 and the inner wall of the guide groove 36; an ear plate 53 is fixed to the side of the guide plate 50; a lifting groove 54 is opened on the surface of the ear plate 53; a limiting groove 55 is opened on the inner wall of the lifting groove 54; the lifting part 38 includes a lifting rod 56 slidably arranged in the lifting groove 54; a limiting rail 57 slidably matched with the limiting groove 55 is fixed on the outer peripheral side of the lifting rod 56; a first ball head 58 is fixed to the bottom end of the lifting rod 56; a supporting spring 59 sleeved on the lifting rod 56 is fixedly connected between the first ball head 58 and the bottom surface of the ear plate 53.

[0049] Working principle of the second embodiment:

[0050] In the initial state, the electromagnetic coil 46 loses power, and the elastic force of the extrusion spring 48 drives the insertion rod 43 to be inserted into the insertion hole 44 on the side of the square rod 28. In this state, the sliding part 30 is fixed on the fixed part 22, the first ball head 58 is pressed against the surface of the upper straight guide plate 23, and the support spring 59 is in a compressed state. During the transportation of the mold box 2, the driving gear 16 meshes with the tooth plate 31 and rotates forward. At the same time, the fixed rod 15 is in contact with the lifting rod 56 during the rotation and forward process, and drives the lifting rod 56 and the retaining frame 37 to slide synchronously along the inner wall of the guide groove 36, and the connecting spring 52 is stretched. In this process, In the process, the first ball head 58 slides along the surface of the upper straight guide plate 23. When the mold box 2 rotates 180°, the ear plate 53 just contacts the second pressure sensor 41. The second pressure sensor 41 transmits the pressure signal to the controller. The controller controls the electromagnetic coil 46 to be energized, attracting the armature column 47, and the extrusion spring 48 is compressed, thereby driving the insertion rod 43 to be pulled out of the socket 44, releasing the limit on the sliding part 30. The mold box 2 drives the sliding part 30 to slide synchronously during the transportation process, and the reset spring 34 is stretched. During this process, the driving gear 16 and the tooth plate 31 remain relatively still, and the tool box 2 remains in a flipped downward state.

[0051] During the continuous conveying process of the mold box 2, the sliding part 30 is driven to slide along the upper straight guide plate 23 toward the lower straight guide plate 24. When the first ball head 58 slides from the upper straight guide plate 23 into the first inclined guide plate 25, the lifting rod 56 is driven to gradually slide down along the ear plate 53 under the elastic restoring force of the support spring 59. When the first ball head 58 slides from the first inclined guide plate 25 into the lower straight guide plate 24, the lifting rod 58 is separated from the fixed rod 15, and the sliding part 30 is driven to move toward the direction close to the side plate 27 under the elastic restoring force of the restoring spring 34. During the reset, the first ball head 58 slides from the lower straight guide plate 24 toward the upper straight guide plate 23 to reset, so as to facilitate the linkage with the next group of mold boxes 2. When the sliding part 30 slides and resets to the first pressure sensor 40 against the side of the baffle 35 when the T-shaped plate 42 is pressed, the first pressure sensor 40 transmits the pressure signal to the controller. The controller controls the electromagnetic coil 46 to lose power, and the elastic reset force of the extrusion spring 48 drives the insertion rod 43 to be inserted into the socket 44 on the side of the square rod 28, so as to complete the fixed limit of the sliding part 30.

[0052] After the demoulding of the precast concrete component 3 and the corresponding mold box 2 is completed, the empty mold box 2 continues to be transported, and when the avoidance grooves 9 on the first belt 7 and the second belt 8 move to the ends of the first belt 7 and the second belt 8, the two sets of avoidance grooves 9 move away from each other, releasing the limit on the mold box 2, and the corresponding mold box 2 is separated from the first belt 7 and the second belt 8, completing the unloading of the mold box 2.

[0053] For example 3, please refer to Figure 1-17, the third embodiment is improved as follows on the basis of the second embodiment. Specifically, an ear rod 60 is fixed to the side surface of the lifting rod 56 near its top; a second ball head 61 is fixed to the end of the ear rod 60; a Z-shaped plate 62 is fixed to the side surface of an ear seat 39; a connecting seat 63 is fixed to the surface of the Z-shaped plate 62; a sliding hole 64 is provided on the side surface of the Z-shaped plate 62; a guide portion 65 slidably matched with the sliding hole 64 is slidably provided on the Z-shaped plate 62; the guide portion 65 includes a vertical guide plate 66; a second inclined guide plate 67 is fixed to the end of the vertical guide plate 66; a guide groove 68 slidably matched with the Z-shaped plate 62 is provided on the side surface of the vertical guide plate 66; a tension spring 69 is fixedly connected between the vertical guide plate 66 and the connecting seat 63; a U-shaped rod 70 slidably matched with the sliding hole 64 is fixed to the top of the vertical guide plate 66.

[0054] A third ball head 71 is fixed to the bottom end of the U-shaped rod 70; a rotating shaft 72 is rotatably provided on the side of the Z-shaped plate 62; a spiral groove 73 is provided on the side of the rotating shaft 72 to slide with the third ball head 71; a plurality of elastic rubber rods 74 are evenly fixed on the side of the rotating shaft 72; a rubber ball 75 is fixed to the end of the elastic rubber rod 74.

[0055] Working principle of the third embodiment:

[0056] When the first ball head 58 slides on the surface of the first inclined guide plate 25, the lifting rod 56 is driven to slide down along the ear plate 53 under the elastic restoring force of the support spring 59. During this process, the second ball head 61 at the end of the ear rod 60 is driven to slide from the vertical guide plate 66 into the side of the second inclined guide plate 67. When the second ball head 61 slides on the second inclined guide plate 67, it gradually squeezes the second inclined guide plate 67, so that the vertical guide plate 66 slides along the Z-shaped plate 62 in the direction away from the mold box 2. The tension spring 69 is stretched, thereby driving the third ball head 71 at the end of the U-shaped rod 70 to slide along the spiral groove 73 on the side of the rotating shaft 72, thereby driving the rotating shaft 72 to rotate, and then driving the elastic rubber rod 74 to rotate. During this process, the rubber rod ball 75 is driven to knock on the bottom surface of the flipped mold box 2, thereby improving the demolding efficiency of the precast concrete component 3 from the corresponding mold box 2.

[0057] A method for using a prefabricated concrete component production device comprises the following steps:

[0058] T1. By placing each group of mold boxes 2 cast with precast concrete components 3 on the conveyor belt 12, when the precast concrete components 3 are completed, the conveyor belt 12 and each first belt 7 and second belt 8 are controlled to drive synchronously, and the rotating holes are used to realize the conveyance of each group of mold boxes 2 one by one.

[0059] T2. In the initial state, the insertion rod 43 is inserted into the insertion hole 44, and the driving gear 16 on the mold box 2 which is synchronously driven with the rotating hole rotates and moves forward on the tooth plate 31, thereby realizing the automatic flipping of the mold box 2. During this process, the mold box 2 drives the retaining frame 37 and the lifting part 38 to slide synchronously on the upper straight guide plate 23.

[0060] T3.
