Description

Technical Field

[0001] This utility model relates to the field of precast concrete block production, and in particular to a precast concrete block production line. Background Technology

[0002] Construction of highways, high-speed railways, water conservancy projects often requires a large number of precast concrete blocks. These blocks are cast from concrete cement. If they are cast in a factory and then transported to the destination, the cost is high. To solve this problem, temporary workshops are now often built next to the construction site. The temporary production equipment mainly includes a vibrating mechanism and a hopper. When in use, a mold is placed on the vibrating mechanism, and a hopper that matches the mold is set above the mold. Before the hopper runs out of material, it is mainly replenished by manually pouring it out. Manual replenishment is not only labor-intensive but also inefficient. Utility Model Content

[0019] Furthermore, the transport hopper is provided with four connecting parts, and a rope is connected to each connecting part;

[0020] The driving component includes fixed pulleys located at the four corners of the first moving trolley for four ropes to pass through. A winding shaft parallel to the axis of the four fixed pulleys is provided between the four fixed pulleys. A reducer is connected to the middle of the winding shaft and a motor connected to it drives the winding shaft to rotate. A set of rope loops is fixed to both sides of the reducer on the winding shaft. Each rope loop has two winding positions for the two ropes on that side to be wound. The two ropes are wound onto the rope loop from above and below the two winding positions, so that they are simultaneously wound up or released as the winding shaft rotates.

[0021] Furthermore, the first mobile trolley includes a frame with four wheels, two of which are controlled by a motor. Dual-motor control prevents slippage.

[0022] Furthermore, the first discharge component includes two arc-shaped sealing plates, and the discharge port is two parallel arc-shaped openings connected to each other to cooperate with the two arc-shaped sealing plates. Each arc-shaped sealing plate has a connecting plate vertically fixed to both ends. The upper end of the connecting plate is hinged to the conveying hopper so that the two arc-shaped sealing plates can be relatively far away from the exposed discharge port and relatively close to the closed discharge port under the action of external force. A first hinge part is provided in the middle of the outer side of each arc-shaped sealing plate, and a second hinge part is provided on the outer side of the conveying hopper above the first hinge part. A second telescopic cylinder is connected between the first hinge part and the second hinge part to control the opening and closing of the arc-shaped sealing plate.

[0023] Furthermore, a third telescopic cylinder is hinged to the top of the discharge pipe near the cover.

A metering hopper is provided below the discharge port and connected to the discharge pipe via a bracket. A second weight sensor is provided between the metering hopper and the bracket. A second discharging component is provided at the bottom of the metering hopper. The second discharging component has the same structure as the first discharging component.

[0024] Furthermore, the bottom of the hopper is provided with two parallel discharge pipes, which improves the casting efficiency.

[0025] Furthermore, the two ends of the base frame are respectively provided with reinforcement ropes.

[0026] Furthermore, the extrusion screw includes a fixed shaft and multiple screw sleeves that are fixedly fitted together. The side of the fixed shaft is formed with a limiting protrusion along the axial direction. Each screw sleeve has a limiting recess that fits with the limiting protrusion on its inner side. Each screw sleeve is divided into two halves along the axial direction to form a semi-shell structure. The two semi-shell structures are respectively provided with screw holes for connection by bolts.

[0027] The advantages of this utility model using the above technical solution are:

[0028] 1. This precast concrete block production line, through the cooperation of a guiding mechanism and a feeding mechanism, can directly transfer concrete cement material from the tanker truck to the transport hopper; through the cooperation of a first moving trolley with the upper running track and a second moving trolley with the lower running track, concrete cement material can be transferred from the transport hopper to the placing hopper; and through the setting of a first weight sensor and a weight display, timely replenishment can be carried out; through the cooperation of a placing mechanism and a vibration mechanism, multiple molds can be placed in the vibration mechanism for sequential pouring. The sequential coordination of the above processes allows for convenient and efficient production of precast concrete blocks. In addition, the structure of the above production line is relatively simple and easy to set up.

[0029] 2. Regarding the vibration mechanism, the combination of the lifting frame and the vibration frame allows for stable vibration of the mold and convenient transfer of the mold after the pouring vibration is complete. Furthermore, to accommodate as many molds as possible, the crossbeam would be quite long and require more than one vibrator. However, this invention segments the crossbeam and configures each segment with a vibrator, thus avoiding resonance between vibrators that could affect the uniformity of the concrete cement.

[0030] 3. Regarding the feeding mechanism, the drive component is connected to the transport hopper by four steel wire ropes, making it relatively stable. It is controlled by a reducer and a motor, ensuring safety and reliability.

[0031] 4. Regarding the feeding mechanism, during the feeding process, the feeding tube can be controlled relatively accurately through the extrusion screw; the feeding accuracy is further increased through the cooperation of the second weight sensor, the third telescopic cylinder and the second feeding component, and the multi-stage control makes it less likely to leak material.

[0032] In addition, because concrete and cement cause significant wear to the extrusion screw, the extrusion screw adopts a bushing fit structure for easy maintenance and replacement. The bushing is made up of two shell-shaped structures spliced ​​together, making replacement and maintenance very convenient.

[0033] 5. The entire production process only requires two operators, one to control the fabric and the other to control the feeding. The operation is very convenient and the labor intensity is low. Attached Figure Description

[0049] To clearly illustrate the technical features of this solution, the present invention will be described in detail below through specific embodiments and in conjunction with the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application; however, this application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this application is not limited to the specific embodiments disclosed below.

[0050] like Figure 1-4 As shown, in this embodiment, the precast concrete block production line includes:

[0051] A basic frame 1 is provided with an upper running track 11 and a lower running track 12 arranged in parallel on the basic frame 1. The lower running track 12 is divided into a material feeding area 13 and a material spreading area 14 from left to right below it.

[0052] The feeding mechanism 2 includes a first moving trolley 21 mounted on the running track 11. A transport hopper 23 is provided below the first moving trolley 21. The transport hopper 23 is connected to a drive component 24 mounted on the first moving trolley 21 by a rope 22, so that the rope 22 can be released and retracted by the drive component 24, so that the transport hopper 23 has a first state located in the feeding area 13 and a second state located between the running track 11 and the lower running track 12. The bottom of the transport hopper 23 is provided with a discharge port and a first discharge component 25 that cooperates with it.

[0053] The material guiding mechanism 3 is located on one side of the feeding area 13 so as to connect the tank truck 6 and the transport hopper 23;

[0054] The fabric feeding mechanism 4 includes several second moving trolleys 41 mounted on the lower running track 12. Each second moving trolley 41 is equipped with a fabric feeding hopper 42, which can be aligned and cooperate with the transport hopper 23 to transfer materials. The bottom of the fabric feeding hopper 42 is equipped with a discharge pipe 43 and an extrusion screw 44. The discharge port of the discharge pipe 43 is equipped with a cover 45. A first weight sensor is provided between the fabric feeding hopper 42 and the second moving trolleys 41. A weight display 46 is provided on the outside of the fabric feeding hopper.

[0055] A vibration mechanism 5 is provided in the fabric area, and a mold that cooperates with the fabric hopper 42 is placed on the vibration mechanism 5.

[0056] Furthermore, to improve production efficiency, a fabric hopper 42 can be equipped with two vibration mechanisms 5, switching the fabric back and forth between the two vibration mechanisms 5. This allows the fabric hopper 42 to work in conjunction with the other vibration mechanism 5 to spread the fabric while transferring the mold on one vibration mechanism 5, thus reducing the idle waiting time of the fabric hopper and improving work efficiency. In addition, such as... Figure 1 The use of double feed hoppers doubles the work efficiency, and the daily production can reach more than 100 cubic meters.

[0057] Working principle: First, concrete cement material is discharged from the tanker truck 6 to the transport hopper 23. Specifically, this is done through the guide mechanism 3, which is movable and its main function is to connect the tanker truck 6 and the transport hopper 23. When the transport hopper 23 is full of material, the drive component 23 lifts the transport hopper 23 to the second state. Then, it moves along the running track 11 with the first moving trolley 21. After reaching above the distribution hopper 42, the first discharging component 25 is operated to release the material in the transport hopper 23. Afterward, the feeding mechanism 2 can return to its original position and transfer material to one or more distribution hoppers as needed.

[0058] Before pouring, multiple molds are placed on the vibrating mechanism 5. The material placing mechanism 4 is moved above the vibrating mechanism 5, and concrete is poured into the molds sequentially, vibrating simultaneously to ensure uniform material distribution within the molds. Once all molds on the vibrating mechanism 5 are full, they are removed, and empty molds are placed for pouring. During this process, if the weight display 46 on the material placing hopper 42 shows a value lower than the set value, material needs to be replenished. This can be done by following the operating procedure of the feeding mechanism 2.

[0059] In actual production, one person can be responsible for feeding the material and another for laying it. The two can work together to easily and efficiently produce precast blocks, such as hexagonal bricks, curb stones, interlocking blocks, cable troughs, drainage covers, hollow bricks, and other precast blocks. For ease of operation, the main unit of the equipment can be operated with a wireless remote control joystick, which is compact, easy to operate, and easy to learn.

[0060] like Figure 5-7 As shown, in one specific embodiment, the vibration mechanism can adopt the following structure: the vibration mechanism 5 includes a fixed frame 51, a vibration frame 52, and a lifting frame 53; the vibration frame 52 is connected to the fixed frame 51 by multiple springs 54, and a vibrator 55 is provided at the bottom of the vibration frame 52; the vibration frame 52 includes a longitudinal beam 521 connected to the springs, and multiple crossbeams 522 are connected parallel to the top of the longitudinal beam 521; the top ends of the crossbeams 522 are respectively provided with first limiting parts 523; the lifting frame 53... The lifting frame 53 is connected above the fixed frame 51 by multiple first telescopic cylinders 56. The lifting frame 53 includes an outer frame 531 arranged around the vibrating frame 52. Multiple first guide rollers 532 are rotatably connected to the outer frame 531, and the multiple first guide rollers 532 and multiple crossbeams 522 are spaced apart. One end of the first guide roller 532 is provided with a gear 533, which drives the first guide roller 532 to rotate through a chain drive structure. A second limiting part 534 is provided on one side of the outer frame 531 to form a three-way limiting with the two first limiting parts 523.

[0061] During the mold casting process, the top of the vibrating frame 52 is higher than the top of the lifting frame 53. That is, the mold is placed on the vibrating frame 52. While casting, the concrete cement material in the mold is uniformly vibrated by the vibrating frame 52. After casting is completed, the lifting frame 53 is raised under the drive of the first telescopic cylinder 56 to support the mold. Then, the first guide roller 532 is rotated by the chain drive structure (not shown in the figure), so that the mold can be transferred away from the unlimited side, which is more convenient.

[0062] Furthermore, the first telescopic cylinder 56 can be a multiplier cylinder, which has a fast operating speed and stable output, has the most compact length size, and features multiple stacked layers, with multiple pistons bearing force simultaneously, thus multiplying the output force of the cylinder. Multi-layer lifting facilitates the cleaning of material residue and waste from gaps in the equipment.

[0063] Furthermore, a roller bed 7 is provided on the side of the vibration mechanism 5 away from the second limiting part 534. Multiple second guide rollers are rotatably connected on the roller bed 7. A drive wheel is provided on one side of the second guide roller. The second guide roller can be driven to rotate by a pulley drive structure or a chain drive structure to realize the movement of the mold on the roller bed. When transferring the mold, a forklift 8 can be set on the side to receive the mold.

[0064] Furthermore, to accommodate as many molds as possible, the crossbeam 522 would typically require a longer length and more than one vibrator 55. However, this invention divides the crossbeam 522 into segments, each equipped with a vibrator 55, thus preventing resonance between the vibrators 55 and ensuring the uniformity of the concrete cement. Specifically, each crossbeam includes a left and a right segment with mating breaks. A vibrator is located at the bottom of the vibrating frame corresponding to each of the left and right segments. The Z-shaped angle bracket design allows the left and right segments to mutually restrain each other during vibration, resulting in higher vibration stability.

[0065] like Figure 8 As shown, in one specific embodiment, the material guiding mechanism 3 includes a material guiding frame 31, on which a material guiding trough plate 32 is provided. One end of the material guiding trough plate 32 is hinged to the material guiding frame 31, and a telescopic member 33 is provided between the other end and the material guiding frame 31 to adjust the guiding angle of the material guiding trough plate. The telescopic member can specifically be an electric telescopic cylinder or a manual telescopic tube. Figure 2As shown, in one specific embodiment, the transport hopper 23 is provided with four connecting parts, each connected to a rope 22; the driving component 24 includes fixed pulleys 241 located at the four corners of the first moving trolley 21 for the four ropes to pass around, and a winding shaft 242 parallel to its axis is provided between the four fixed pulleys 241. A reducer 243 is connected to the middle of the winding shaft 242 and a motor 244 connected to it drives the winding shaft 242 to rotate. A set of rope loops 245 are fixed to both sides of the reducer on the winding shaft 242. Each set of rope loops 245 is provided with two winding positions for the two ropes 22 on that side to be wound, and the two ropes 22 are wound onto the rope loops 245 from above and below the two winding positions, so that they are simultaneously wound up or released as the winding shaft rotates.

[0066] Furthermore, the first mobile trolley 21 includes a frame with four wheels, two of which are controlled by a motor. The dual-motor control prevents slippage.

[0067] Furthermore, the first discharge component 25 includes two arc-shaped sealing plates 251. The discharge port is two parallel arc-shaped openings connected to each other to cooperate with the two arc-shaped sealing plates 251. Each arc-shaped sealing plate 251 has a connecting plate 252 vertically fixed to both ends. The upper end of the connecting plate 252 is hinged to the conveying hopper 23 so that the two arc-shaped sealing plates 252 can be relatively far away from the exposed discharge port and relatively close to the closed discharge port under the action of external force. Each arc-shaped sealing plate 251 has a first hinge part in the middle of its outer side. The outer side of the conveying hopper above the first hinge part has a second hinge part. A second telescopic cylinder 253 is connected between the first hinge part and the second hinge part to control the opening and closing of the arc-shaped sealing plate.

[0068] like Figure 3-4 As shown, in one specific embodiment, a third telescopic cylinder 47 is hinged to the top of the discharge pipe 43 near the top of the cover 45. The cover 45 is hinged to the output end of the discharge pipe 43 and the third telescopic cylinder 47 via a connecting rod 48, so that the discharge port can be opened and closed by extending and retracting the third telescopic cylinder 47. A metering hopper 49 is provided below the discharge port and connected to the discharge pipe 43 via a bracket. A second weight sensor is provided between the metering hopper 49 and the bracket. A second discharging component 410 is provided at the bottom of the metering hopper 49. The second discharging component can have the same structure as the first discharging component, or it can adopt the following structure: Specifically, the upper ends of the two connecting plates of the two arc-shaped sealing plates are engaged, and one of the arc-shaped sealing plates is driven by a second telescopic cylinder, so that the two arc-shaped sealing plates can be opened or closed simultaneously.

[0069] Furthermore, the bottom of the cloth hopper 42 is provided with two parallel discharge pipes 43, which improves the casting efficiency.

[0070] Furthermore, since concrete and cement cause significant wear to the extrusion screw, the extrusion screw can adopt the following structure for easy maintenance and replacement: The extrusion screw 44 includes a fixed shaft and multiple screw sleeves that cooperate with the fixed shaft. The side of the fixed shaft forms a limiting protrusion along the axial direction, and the inner side of each screw sleeve forms a limiting recess that cooperates with the limiting protrusion. This cooperation allows the screw sleeve to rotate with the fixed shaft. Each screw sleeve is divided into half along the axial direction to form a semi-shell structure. The two semi-shell structures are respectively provided with screw holes for connection by bolts. With this arrangement, any semi-shell structure can be replaced as needed without removing the other semi-shell structures, which is more convenient.

[0071] like Figure 1 As shown in Figure 9, in one specific embodiment, the two ends of the base frame 1 are respectively provided with reinforcement ropes 15.

[0072] The above specific embodiments should not be construed as limiting the scope of protection of this utility model. For those skilled in the art, any alternative improvements or modifications made to the embodiments of this utility model shall fall within the scope of protection of this utility model.

[0073] Any aspects of this utility model not described in detail are known to those skilled in the art.
