Description

Technical Field

[0001] This utility model belongs to the field of civil engineering sample preparation, specifically relating to a civil engineering sample preparation device. Background Technology

[0002] Sample preparation refers to the process of processing raw materials (such as concrete, metal, plastic, soil, etc.) into samples of a certain shape, size, and properties according to specific standards, specifications, or experimental requirements, so that they can be used for subsequent physical property testing, chemical analysis, mechanical testing, or other scientific experiments.

[0003] During the sample preparation process, when leveling the concrete at the top of the discharge trough, excess concrete often spills onto the ground, causing environmental pollution and making cleaning difficult. During the process of filling the discharge trough with concrete, gaps often exist between the concrete particles. If these gaps are not eliminated, they will affect the quality and strength of the sample. However, the current method of manually stirring to remove bubbles during sample preparation is inefficient. After the concrete sample is formed, demolding is often a difficult process. Improper demolding may lead to damage or deformation of the sample.

[0004] Therefore, existing civil engineering projects have problems such as excessive concrete pollution of the ground environment, difficulty in eliminating concrete voids, and difficulty in demolding during the sample preparation process. Utility Model Content

A vibrating motor for vibrating and removing voids in concrete is installed at the lower end of the bearing plate. Two collection boxes are centrally symmetrically distributed at the upper end of the bearing plate. A mold is positioned at the upper end of the bearing plate, and two discharge slots for subsequent solidification are opened at the upper end of the mold. Fixed inclined blocks are fixed to the left and right ends of the mold. A protruding inclined block is fixed to the upper end of the collection box, with the upper surface of the protruding inclined block and the lower surface of the fixed inclined block fitting together. An insertion slot is opened at the upper end of the mold, and a magnetically placed insertion block of appropriate size is placed in the slot. Lifting bent blocks are fixed to the front and rear ends of the insertion block.

[0007] Preferably, the upper end of the vibrating base plate is fixedly connected to two support columns, and two slide rods are slidably installed on the support columns.

A connecting plate is fixedly connected to the upper end of the bearing frame. The upper end of the connecting plate and the lower end of the bearing plate are fixedly connected to each other. A spring is sleeved on the outer wall of the slide rod at the end of the bearing frame and the support column that are close to each other.

[0008] Preferably, the upper end of the bearing plate is fixed with four first limiting posts, and the lower end of the mold is provided with four first limiting grooves. The first limiting grooves and the first limiting posts correspond to each other and are compatible.

[0009] Preferably, two studs are fixed to each of the front and rear ends of the bearing plate, and the outer walls of the studs are sequentially provided with clamping blocks for clamping the collection box and nuts for fixing the clamping blocks by thread.

[0010] Preferably, the collection box is a U-shaped object, with two second limiting posts fixed to one end and two second limiting slots opened at the other end.

[0013] The beneficial effects of this utility model are as follows: The normal manufacturing process involves spraying a release agent into the discharge trough and injecting concrete. Then, by turning on the vibration motor, the gaps in the concrete filling the discharge trough are eliminated through vibration. Next, a scraper is used to level the upper end of the discharge trough. The leveled concrete is collected using the fixed inclined blocks on the mold and the inclined surfaces on the collection box.

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please see Figures 1-6This utility model provides an embodiment of a civil engineering sample preparation device, including a support plate 1; it also includes a collection box 3 and an insertion block 206. A vibration motor 404 for vibrating and removing voids in the concrete filling is installed at the lower end of the support plate 1. Two collection boxes 3 are centrally symmetrically distributed at the upper end of the support plate 1. A mold 2 is positioned at the upper end of the support plate 1. Two discharge grooves 201 for subsequent solidification are opened at the upper end of the mold 2. Fixed inclined blocks 203 are fixed to the left and right ends of the mold 2. A protruding inclined block 303 is fixed to the upper end of the collection box 3. The upper end of the inclined surface of the protruding inclined block 303 and the lower inclined surface of the fixed inclined block 203 are in contact with each other. An insertion groove 204 is opened at the upper end of the mold 2, and a magnetically placed sample of suitable size is placed in the insertion groove 204. Insertion block 206, with lifting bends 207 fixed to both ends of insertion block 206. After normal manufacturing steps, release agent is sprayed into the discharge trough 201 and concrete is injected. Then, the vibration motor 404 is turned on to eliminate the gaps in the concrete filling the discharge trough 201 by vibration. Next, the upper end of the discharge trough 201 is leveled by scraping. The leveled concrete can be collected by the fixed inclined block 203 on the mold 2 and the inclined surface on the collection box 3. After molding, the insertion block 206 is removed from the insertion groove 204 by pulling the lifting bends 207 on the outer side of the insertion block 206. Then, the lifting bends 207 on the inner side form small grooves on the concrete block to facilitate the subsequent demolding of the concrete.

[0023] Please see Figures 1-2 In this embodiment, two support columns 401 are fixedly connected to the upper end of the vibrating base plate 4. Two sliding rods 402 are slidably arranged on the support columns 401. A bearing frame 403 is fixedly connected to one end of the two sets of sliding rods 402 that are close to each other. The vibrating motor 404 is arranged on the bearing frame 403. A connecting plate 405 is fixedly connected to the upper end of the bearing frame 403. The upper end of the connecting plate 405 and the lower end of the bearing plate 1 are fixedly connected to each other. A spring 406 is sleeved on the outer wall of the sliding rod 402 at the end of the bearing frame 403 and the support column 401 that are close to each other. After the vibrating motor 404 is turned on, the bearing frame 403 shakes and drives the sliding rod 402 to slide on the support column 401. During the sliding, the vibration frequency of the connecting plate 405 is increased by the action of the spring 406, thereby eliminating gaps in the concrete in the discharge trough 201.

[0024] Please see Figures 3-6In this embodiment, four first limiting posts 101 are fixedly connected to the upper end of the support plate 1, and four first limiting grooves 202 are provided at the lower end of the mold 2. The first limiting grooves 202 and the first limiting posts 101 correspond one-to-one and are compatible. The mold 2 is inserted into the first limiting posts 101 through the first limiting grooves 202 for positioning. Two studs 102 are fixedly connected to each of the front and rear ends of the support plate 1. The outer wall of the studs 102 is sequentially provided with clamping blocks 103 for clamping the collection boxes 3 and nuts 104 for fixing the clamping blocks 103 are threadedly installed. When the two collection boxes 3 are placed on the support plate 1, by rotating the nuts 104, the clamping blocks 103 on both sides of the support plate 1 move closer to each other, thereby clamping and fixing the two collection boxes 3. The collection box 3 is a U-shaped object, with two second limiting grooves fixed to one end. The limiting post 301 has two second limiting grooves 302 at its other end. The second limiting grooves 302 and the second limiting post 301 are adapted to each other. Two centrally symmetrical collection boxes 3 are inserted into each other's second limiting grooves 302 through the second limiting post 301 and placed in close contact. The upper end of the collection box 3 is fixed with a protruding inclined block 303. The inner wall of the protruding inclined block 303 is flush with the inner wall of the collection box 3. The inner wall of the collection box 3 is in close contact with the four outer walls of the mold 2. Excess concrete after being scraped on the mold 2 is collected through the upper recess of the collection box 3 to prevent subsequent ground pollution and cleaning difficulties. The lower end of the insertion groove 204 is provided with a first magnet 205, and the lower end of the insertion block 206 is provided with a second magnet 208. The second magnet 208 and the first magnet 205 are magnetically attracted to each other.

[0025] During installation, firstly, align the first limiting groove 202 on mold 2 with the first limiting post 101 on bearing plate 1 and insert it. Then, slide the two collection boxes 3 from the front and rear ends of mold 2 (the protruding inclined block 303 should be slidably placed at the lower end of the fixed inclined block 203) so that the two collection boxes 3 fit tightly against the outside of mold 2. Next, rotate the nut 104 on stud 102 to clamp the two collection boxes 3 with the four clamping blocks 103. Then, place the two lifting bent blocks 207 into the insertion groove 204 through the magnetic attraction structure formed by the second magnet 208 and the first magnet 205. Next, spray the release agent into the discharge groove 201. After completion, inject concrete into the discharge groove 201. Then, turn on the vibration motor 404. When the vibration motor 404 is working, it drives the sliding rod. 402 slides on the support column 401, and the spring 406 increases the amplitude of the shaking, thereby causing the bearing plate 1 at the upper end of the connecting plate 405 to shake. The vibration eliminates the gaps in the concrete filling the discharge trough 201. Then, the upper end of the discharge trough 201 is leveled by using a scraper. The leveled concrete can be collected by the fixed inclined block 203 on the mold 2 and the inclined surface on the collection box 3. After molding, the insertion block 206 is removed from the insertion slot 204 by pulling the lifting bend 207 on the outer side of the insertion block 206. Then, the inner lifting bend 207 forms a small groove on the concrete block, which facilitates the subsequent demolding of the concrete. This solves the problems of excess concrete polluting the ground environment, difficulty in eliminating gaps, and difficulty in demolding during the sample preparation process.
