Technical Field
[0001] This utility model belongs to the field of precast block processing technology, and in particular relates to a reinforced precast block processing equipment. Background Technology
[0002] Precast blocks are a frequently used building structure in water conservancy engineering construction. Specifically, in emergency water conservancy operations, because precast blocks are manufactured in advance, the construction of structures, such as dam reinforcement structures, can be completed simply by assembling the precast blocks. Therefore, precast blocks not only significantly reduce the construction period but also effectively reduce construction difficulty. Thus, for emergency construction projects with short timeframes, precast blocks greatly increase construction efficiency compared to traditional on-site concrete casting.
[0003] In the production of precast blocks, the blocks are produced on a precast block conveyor line. Specifically, the molds for the precast blocks are placed on the conveyor line, and the material feeding equipment on the conveyor line feeds concrete into the molds, achieving the simultaneous filling of concrete into the molds and the transport of the molds on the production line. However, when the molds are transported to the discharge end of the production line, the current feeding method involves manual handling of the molds, which are very heavy due to the concrete filling. While traditional mechanical equipment such as cranes can lift the molds, the steel cables on the cranes are difficult to secure to the molds, and the securing time is relatively long. After securing and lifting, it is also difficult to maintain the balance of the molds during lifting, and in an unbalanced state, the concrete is prone to tipping over from the molds.
[0004] Therefore, although mechanical lifting is less labor-intensive than manual handling, it has a higher rate of inflexibility and failure.
[0005] Therefore, a rapid feeding device can not only greatly reduce the difficulty of feeding and improve work efficiency, but also significantly reduce production costs and increase production efficiency. Utility Model Content
[0006] Based on the above background, the purpose of this utility model is to provide a reinforced precast block processing equipment.
[0007] To achieve the above objectives, the present invention adopts the following technical solution:
[0008] A reinforced precast block processing equipment includes a precast block mold gripping and unloading mechanism that cooperates with the precast block conveyor line;
[0009] The precast block mold feeding mechanism includes an upper feeding frame, and a number of gripping plates for squeezing and gripping the precast block mold are slidably connected to the bottom of the upper feeding frame. Long slide rails are slidably connected to both ends of the gripping plates.
[0010] Several spring segments are sleeved on the long slide rail, and the two ends of each spring segment are fixed to the adjacent gripper plate.
[0011] The precast block mold feeding mechanism also includes a push cylinder structure that pushes the gripping plates closer together and presses them against the precast block mold;
[0012] The push cylinder structure includes push cylinders respectively installed on both sides of the upper gripper frame, and the piston rod of the push cylinder is installed on the gripper plate;
[0013] The precast block mold material handling and feeding mechanism also includes a support rod structure for holding the bottom of the precast block mold.
[0014] Preferably, the upper material gripper includes a slide rail frame that is spaced apart at the front and rear, and a crossbeam frame is fixedly connected between the ends of the two ends of the slide rail frame.
[0015] Preferably, the bottom of the slide rail frame is provided with T-shaped limiting slide grooves, and the front and rear sides of the top of the grab plate are respectively fixedly connected to T-shaped slide seats that are limited to sliding in the T-shaped limiting slide grooves.
[0016] Preferably, three springs are fitted onto the long slide rail;
[0017] The gripper plate has sliding openings on both sides, and a sliding sleeve that mates with a long slide rail is installed in the sliding openings.
[0018] The long slide rail is slidably connected inside the slide sleeve, and two ends of the long slide rail are respectively fixedly connected to the baffle seats.
[0019] Preferably, a hanging bracket is fixedly connected to both sides of the top of the slide rail frame, and the hanging bracket is installed on the crane.
[0020] Preferably, cylinder brackets are fixedly installed at the bottom of the crossbeam frame, and the cylinder barrel of the push cylinder is fixedly installed on the cylinder brackets.
[0021] Preferably, the lever structure includes U-shaped levers that are rotatably connected to the slide rail frame.
[0022] The boom structure also includes motors for driving the rotation of the U-shaped boom.
[0023] Preferably, the two ends of the U-shaped support rod are respectively hinged to the end positions of the slide rail frame by fixing pins, and the output shaft of the motor is fixedly installed at one end of the U-shaped support rod.
[0024] Preferably, the motor is equipped with a motor mounting bracket, which is fixedly mounted on the crossbeam frame.
[0025] This utility model has the following beneficial effects:
[0026] 1. During operation, driven by the cylinder, the two side gripping plates press against each other, bringing the three molds close to the conveyor. During this process, the gripping plates, along with other gripping plates, compress the molds together. Then, the crane lifts the molds. The gripping plates simultaneously lift the three molds. When the material is hoisted onto subsequent equipment such as a stacking rack, the cylinder closes, and the elastic restoring force of the three springs causes the gripping plates to move away from the molds, facilitating unloading.
[0027] The above methods not only greatly improve the efficiency of precast block mold cutting during the production process, but also save labor during the cutting process, significantly reduce the amount of labor involved in cutting, greatly increase production efficiency, increase production capacity, and reduce labor costs for cutting.

This method provides further support and protection for the mold and further improves the stability of the mold during the lifting process. Attached Figure Description

[0039] Example 1
[0040] like Figure 1-5 As shown, a reinforced precast block processing equipment includes a precast block mold gripping and unloading mechanism (located at the discharge end of the conveyor) that cooperates with a precast block conveyor line (not shown in the figure).
[0041] Specifically, the precast block conveyor line is an existing production line for producing precast blocks, which includes a conveyor and a feeding device installed on the conveyor to load and unload concrete. The precast block molds are transported on the conveyor and filled with concrete by the feeding device.
[0042] To achieve a labor-saving and efficient material feeding method for the mold, the aforementioned precast block mold material feeding mechanism includes an upper material feeding frame. Specifically, the upper material feeding frame includes a slide rail frame 11 spaced at the front and rear, with a crossbeam frame 12 fixedly connected between the ends of the slide rail frame 11. Meanwhile, T-shaped limiting grooves 112 are respectively opened at the bottom of the slide rail frame 11, and T-shaped slide blocks 211, which slide within the T-shaped limiting grooves 112, are fixedly connected to the front and rear sides of the top of the gripping plate.
[0043] The bottom of the aforementioned upper gripping frame is slidably connected to four gripping plates 21 for extruding and gripping precast block molds. Each gripping plate 21 has a long, cylindrical slide rail 22 slidably connected to both ends. (Specifically, each gripping plate 21 has a sliding opening on both sides, and a sliding sleeve, made of stainless steel, is installed inside the opening to mate with the long slide rail 22, reducing wear between the long slide rail 22 and the sliding sleeve. Specifically, the long slide rail 22 is slidably connected inside the sliding sleeve, and each end of the long slide rail 22 is fixedly connected to a spacer seat to prevent the gripping plate 21 from detaching.) Simultaneously, three spring segments 23 are sleeved on the long slide rail 22, with both ends of each spring segment fixed to the adjacent gripping plate 21 (on the side walls of the adjacent gripping plates 21 facing each other).
[0044] Meanwhile, the aforementioned precast block mold feeding mechanism also includes a push cylinder structure that pushes the gripping plates 21 closer together and squeezes them onto the precast block mold.
[0045] Specifically, the push cylinder structure includes push cylinders 24 respectively installed on both sides of the upper gripper frame, and the piston rod of the push cylinder 24 is installed on the gripper plate 21. Specifically, one end of the piston rod of the push cylinder 24 is fixed to the gripper plate 21. In particular, cylinder brackets 241 are fixedly installed at the bottom of the crossbeam frame 12, and the cylinder barrel of the push cylinder 24 is fixedly installed on the cylinder brackets 241.
[0046] The gripper plate 21 has the following shape: the gripper plate 21 includes a trapezoidal part and a rectangular part integrally formed at the bottom of the trapezoidal part.
[0047] The top two sides of the slide rail frame 11 are respectively fixedly connected to the hanging seats 111, and the hanging seats 111 are installed on the crane (not shown in the figure).
[0048] Specifically, during the operation, four steel wire ropes are installed on the crane and suspended from the hanging base 111 (with hooks fixedly connected to the steel wire ropes). Driven by the push cylinder 24, the two side gripping plates 21 press against each other, bringing the three molds closer to the conveyor. During this process, the gripping plates 21 press against the molds, and the gripping plates 21 in other positions press the three molds together (the molds are on the conveyor, and the rollers on the conveyor provide rolling support between the molds and the rollers, so all molds easily move and are pressed together during the pressing process). Then, the crane lifts the molds. Under the pressure of the gripping plates 21, the three molds are lifted simultaneously.
[0049] In actual operation, because the top edge of the mold has a flange, when the gripper 21 is squeezed, the top of the gripper 21 is positioned at the bottom of the flange, which can maintain the stability of the mold after lifting.
[0050] When the material is hoisted onto subsequent equipment such as a stacking rack, the cylinder is closed by the elastic restoring force of the three springs 23, and the gripping plates 21 move away from the mold to facilitate unloading.
[0051] The above methods not only greatly improve the efficiency of precast block mold cutting during the production process, but also save labor during the cutting process, significantly reduce the amount of labor involved in cutting, greatly increase production efficiency, increase production capacity, and reduce labor costs for cutting.
[0052] Example 2
[0053] like Figure 1-5 As shown, based on the structure of Embodiment 1, in order to avoid the defect of the mold falling after being lifted due to the gripping plate 21 not being gripped tightly during the working process, the above-mentioned precast block mold gripping and unloading mechanism also includes a support rod structure for supporting the bottom position of the precast block mold.
[0054] Specifically, the lever structure includes U-shaped levers 31 that are rotatably connected to the slide rail frame 11; the lever structure also includes motors 32 for driving the U-shaped levers 31 to rotate.
[0055] Specifically, the two ends of the U-shaped support rod 31 are respectively hinged to the end positions of the slide rail frame 11 by fixed pins, and the output shaft of the motor 32 is fixedly installed on one end of the U-shaped support rod 31. A motor mounting bracket is installed on the motor 32, and the motor mounting bracket is fixedly installed on the crossbeam frame 12.
[0056] During operation, after the entire device is lifted, the U-shaped support rod 31 flips over and is positioned between the bottom of the mold under the drive of the motor 32. This method provides further support and protection for the mold and further improves the stability of the mold during the lifting process.
[0057] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
