Description

Technical Field

[0001] This utility model belongs to the technical field of concrete vibration table, and specifically relates to a concrete vibration table. Background Technology

[0002] In the field of concrete processing, concrete molds are often used to make test blocks and related products. Given the small size of these molds, it is inconvenient to use concrete vibrators for compaction; therefore, vibrating tables are often chosen instead. Vibrating tables, with their high-frequency vibration efficiency, can promote uniform filling of the concrete within the mold, effectively avoiding defects such as large areas of air pockets and broken blocks caused by uneven filling during demolding.

[0003] Traditional concrete vibrating tables typically place the concrete-filled mold directly on the table surface without any mold securing device, making it prone to slippage. During this slippage, the originally uniform vibration force field within the mold is disrupted, resulting in uneven stress on the concrete. If one side of the mold suddenly shifts, the vibration force on that side decreases, causing an imbalance in the compaction process within the mold. Some areas are over-vibrated, while others are under-vibrated, ultimately leading to inconsistent concrete density and affecting the final product quality. Therefore, an alternative concrete vibrating table is provided to address these technical problems. Utility Model Content

[0004] To address the problem that existing concrete vibrating tables lack a mold fixing mechanism, resulting in poor concrete venting during vibration and affecting the quality of the final product, this invention provides a concrete vibrating table. By incorporating lugs with threaded rods and fitting positioning frames onto these rods, the positioning frames are secured using locking devices. In practical applications, the concrete mold can be placed within the positioning frame's opening for restraint, preventing slippage and thus achieving a stable amplitude. This ensures optimal concrete venting, guaranteeing the quality of the final product and effectively solving the problem of existing concrete vibrating tables lacking a mold fixing mechanism and resulting in poor concrete venting during vibration, thus affecting the quality of the final product. The specific technical solution is as follows:

[0005] A concrete vibration table includes a vibration table body. Two lugs are fixedly installed on the left and right sides of the vibration table body. Threaded rods are vertically fixedly installed on the upper surface of each lug. A positioning frame is sleeved between the four threaded rods. Locking elements for fixing the positioning frame are screwed onto the outer surface of each threaded rod. A placement opening is provided through the upper surface of each positioning frame. The size of the placement opening matches the size of the concrete mold. A cleaning plate is detachably installed on the upper surface of the positioning frame.

[0006] In the above technical solution, the locking components all include a lifting nut and a locking nut. The lifting nut and the locking nut are screwed onto the outer surface of the corresponding threaded rod, and the positioning frame is clamped between the lifting nut and the locking nut.

[0007] In the above technical solution, two side baffles are symmetrically fixedly installed on the upper surface of the positioning frame, and a slot is opened on the upper surface of the positioning frame. The cleaning plate is inserted into the slot, and the cleaning plate and the two side baffles are combined to form a enclosure structure.

[0008] In the above technical solution, the upper surface of the side baffle is provided with a slot, and the lower surface of the cleaning plate is symmetrically provided with two sliding grooves. The sliding grooves are engaged in the corresponding slots, and when the sliding grooves are engaged in the outer surface of the side baffle, the lower surface of the cleaning plate is in contact with the upper surface of the positioning frame.

[0009] In the above technical solution, a guide hopper is fixedly installed on the front surface of the positioning frame.

[0010] The concrete vibrating table of this utility model has the following advantages compared with the prior art:

[0011] I. This utility model sets up an ear block with a threaded rod, and after the positioning frame is fitted on the threaded rod, the positioning frame is fixed by a locking device. In practical applications, the concrete mold can be placed into the placement opening of the positioning frame for limitation, which can prevent it from sliding, thereby obtaining a stable amplitude, achieving the best concrete venting effect, and ensuring the quality of the final product.

[0012] II. This utility model clamps and fixes the positioning frame by placing it on the threaded rod and then locking the nut with a lifting nut machine. It can be adjusted according to the actual height of the concrete mold, so that the upper surface of the positioning frame is flush with the upper surface of the concrete mold, which facilitates the use of a cleaning plate to uniformly scrape the concrete mold.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] In this embodiment, front, back, left, right, top, and bottom are... Figure 1 Describe the reference plane. See [link / reference] Figures 1-3 This utility model provides a technical solution:

[0019] A concrete vibration table includes a vibration table body 1. Two lugs 2 are fixedly installed on the left and right sides of the vibration table body 1. Threaded rods 3 are vertically fixedly installed on the upper surface of each lug 2. A positioning frame 4 is sleeved between the four threaded rods 3. Locking parts for fixing the positioning frame 4 are screwed onto the outer surface of each threaded rod 3. A placement opening 41 is opened through the upper surface of each positioning frame 4. The size of the placement opening 41 matches the size of the concrete mold. A cleaning plate 5 is detachably installed on the upper surface of the positioning frame 4.

[0020] Combination Figure 1 and Figure 3 As shown, the concrete mold containing concrete is placed into the placement port 41 of the positioning frame 4, so that the lower surface of the concrete mold is in contact with the vibration table surface of the vibration table body 1. Then, an external collection box is placed below the front end of the positioning frame 4. Subsequently, the concrete exceeding the height of the concrete mold is hung down using the cleaning plate 5 and pushed forward to push the excess concrete away from the positioning frame 4 and fall into the external collection box for collection. Finally, the vibration table body 1 is started to perform vibration and degassing operations on the concrete. During the vibration and degassing process, the concrete mold is restricted by the positioning frame 4, which can effectively prevent it from sliding, thereby achieving a stable amplitude and achieving the best concrete degassing effect, ensuring the quality of the final product.

[0021] It should be noted that, as Figure 2 As shown, the locking components all include a lifting nut 31 and a locking nut 32. The lifting nut 31 and the locking nut 32 are screwed onto the outer surface of the corresponding threaded rod 3, and the positioning frame 4 is clamped between the lifting nut 31 and the locking nut 32.

[0022] In actual use, the lifting nut 31 can be rotated to adjust the lifting height of the positioning frame 4, so that the position of the upper surface of the positioning frame 4 can be adjusted according to the concrete mold of different heights, so that the cleaning plate 5 can scrape off the excess material. After adjusting to the appropriate lifting position, the locking nut 32 is screwed onto the outer surface of the threaded rod 3, so that the lower surface of the locking nut 32 fits against the upper surface of the positioning frame 4 and is locked.

[0023] In addition, to prevent concrete residue from spilling outwards from the positioning frame 4 and affecting collection, two side baffles 42 are symmetrically fixed on the upper surface of the positioning frame 4, and slots 43 are provided on the upper surface of the positioning frame 4. The cleaning plate 5 is inserted into the slots 43. The cleaning plate 5 and the two side baffles 42 are combined to form a barrier structure. The barrier structure formed by the combination can be used to cover the scattered concrete residue and ensure that the residue can be discharged uniformly from the right end of the positioning frame 4.

[0024] In addition, in order to enable the cleaning plate 5 to easily conform to the upper surface of the positioning frame 4 and move forward during the process of pushing the residual material, slots 421 are provided on the upper surface of the side baffle 42, and two sliding grooves 51 are symmetrically provided on the lower surface of the cleaning plate 5. When the cleaning plate 5 is inserted into the slot 43 on the positioning frame 4, the sliding groove 51 is engaged in the corresponding slot 421. When the sliding groove 51 is engaged in the outer surface of the side baffle 42, the lower surface of the cleaning plate 5 is in contact with the upper surface of the positioning frame 4. At this time, pressing down the cleaning plate 5 and moving it forward can push the residual concrete on the positioning frame 4 and make it detach from the positioning frame 4.

[0025] Finally, to facilitate the collection of fallen concrete residue, a guide hopper 6 is fixedly installed on the front surface of the positioning frame 4. The guide hopper 6 can be used to accurately guide the concrete residue into the collection box outside the positioning frame 4.
