Technical Field
[0001] The present application relates to the technical field of concrete, and in particular to a demoulding device for concrete test blocks. Background Art
[0002] A concrete test block is a product prepared during the concrete test process and used to test the performance of concrete. After the concrete test block is formed in a mold, it usually needs to be demolded for subsequent maintenance and testing. The concrete needs sufficient time to solidify and harden in the mold to ensure that the test block has sufficient strength.
[0003] Concrete test blocks are formed in molds and need to be demolded after forming. Generally, demolding is done manually by knocking the mold with tools. Once the test block is loosened, it can be removed from the mold. This method is time-consuming, labor-intensive, inefficient, labor-intensive, and easily causes mold damage. Utility Model Content
[0004] In view of the shortcomings of the prior art, the present application provides a demoulding device for concrete test blocks, which has the advantages of easy disassembly, etc., and solves the problem that the concrete test blocks are formed in the mold and need to be demoulded after forming. Generally, manual demoulding is adopted, and the mold is knocked with a tool. After the test block is loosened, it can be separated from the mold. This method is time-consuming and labor-intensive, inefficient, labor-intensive, and easily causes mold damage.
[0005] To achieve the above-mentioned purpose, the present application provides the following technical solutions: a demolding device for concrete test blocks, comprising a support frame and an end cover, the upper end of the support frame is fixedly connected to a base plate, the lower end of the base plate is fixedly connected to a vibration motor, the upper end of the base plate is fixedly connected to two first side plates distributed in a mirror image, connecting grooves are provided inside both sides of the base plate, connecting blocks are slidably connected inside the two connecting grooves, the upper ends of the two connecting blocks are fixedly connected to the second side plates, a clamping groove is provided inside the connecting block, a sliding block is slidably connected inside the clamping groove, the length of the sliding block is equal to the length of the clamping groove, and a sliding groove is provided inside the base plate near the connecting groove.
[0006] A spring is fixedly connected to one side of the sliding groove, a clamping block is slidably connected to the sliding groove, one end of the clamping block is fixedly connected to one end of the spring, and one end of the clamping block away from the spring abuts against the sliding block.
[0007] According to the above scheme, a vibration motor is fixedly connected to the lower end of the bottom plate. During use, when the concrete is completely solidified and hardened, the vibration motor is started, and the vibration motor drives the bottom plate to vibrate and transmits the vibration to the two first side plates and the two second side plates, so that the concrete block is separated from the first side plate and the second side plate. Then, the end cover is removed, and then the top column is pressed to move the top column toward the bottom plate until the end of the retaining ring close to the sliding block abuts against the end of the mounting groove close to the bottom plate. During the movement of the top column, the sliding block is driven to move, because the distance between the end of the retaining ring close to the sliding block and the end of the mounting groove close to the bottom plate is the same as the length of the sliding block, so when the retaining ring abuts against one side of the mounting groove, the sliding block will completely enter the inside of the card slot. At the same time, because the length of the sliding block is the same as the length of the card slot, during the movement of the sliding block, the card slot will be pushed out of the card slot. At this time, the connecting block and the connecting slot can slide relative to each other, and then the two second side plates are pulled upward, and the second side plates are taken out to remove the concrete block, and the labor intensity of the staff can be reduced during the removal process.
[0008] Furthermore, mounting columns are fixedly connected to positions on both sides of the bottom plate surface corresponding to the second side plates, mounting grooves are provided inside the mounting columns, and top columns are slidably connected inside the mounting grooves.
[0009] According to the above solution, pressing the top column during use will cause the top column installation slot to move in the length direction.
[0010] Furthermore, a retaining ring is fixedly connected to the surface of the top column, and one end of the top column close to the sliding block extends into the bottom plate and abuts against the end of the sliding block away from the blocking block, and the end of the top column away from the sliding block passes through one end of the mounting column, and the distance from the end of the retaining ring close to the sliding block to the end of the mounting groove close to the bottom plate is equal to the length of the sliding block.
[0011] According to the above solution, when the top column is pressed during use, the top column will drive the sliding block to move in the direction of the card slot during the movement of the top column until the sliding block completely enters the card slot.
[0012] Furthermore, a locking bolt is fixedly connected to the middle of the surfaces of the two second side panels, and a mounting frame is fixedly connected to the middle positions of both sides of the end cover corresponding to the locking bolt, and locking hooks corresponding to the locking bolt are rotatably connected inside the two mounting frames.
[0013] Through the above solution, when in use, the lock hook is rotated so that the lock bolt is inserted into the lock hook, and the end cover can be fixed to the upper ends of the two second side plates.
[0014] Furthermore, a handle is fixedly connected to the middle portion of the upper end of the end cover.
[0015] According to the above solution, the whole device can be lifted by holding the handle during use, and the end cover can be removed by the handle after the lock hook is separated from the lock bolt.
[0016] Furthermore, two mirror-distributed sealing grooves are provided inside the two first side panels, and sealing strips corresponding to the sealing grooves are fixedly connected at both ends of the two second side panels. The sealing strips extend into the sealing grooves and tightly abut against the inner walls of the sealing grooves, and the sealing strips are slidably connected to the inner walls of the sealing grooves.
[0017] Through the above solution, the sealing groove cooperates with the sealing strip during use, which can prevent concrete from flowing out of the gap between the first side plate and the second side plate as much as possible during the concrete pouring process.
[0018] Compared with the prior art, the technical solution of this application has the following beneficial effects:
[0019] The demoulding device for concrete test blocks has a vibration motor fixedly connected to the lower end of a bottom plate. During use, when the concrete is completely solidified and hardened, the vibration motor is started, and the vibration motor drives the bottom plate to vibrate and transmits the vibration to the two first side plates and the two second side plates, so that the concrete block is separated from the first side plate and the second side plate. Then, the end cover is removed, and then the top column is pressed to move the top column toward the bottom plate until the end of the retaining ring close to the sliding block abuts against the end of the mounting groove close to the bottom plate. During the movement of the top column, the sliding block is driven to move, because the distance between the end of the retaining ring close to the sliding block and the end of the mounting groove close to the bottom plate is the same as the length of the sliding block, so when the retaining ring abuts against one side of the mounting groove, the sliding block will completely enter the inside of the card slot. At the same time, because the length of the sliding block is the same as the length of the card slot, during the movement of the sliding block, the card slot will be pushed out of the card slot, and at this time, the connecting block and the connecting slot can slide relatively, and then the two second side plates are pulled upward, and the second side plates are taken out to remove the concrete block, and the labor intensity of the staff can be reduced during the removal process.
