Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a cutting device for autoclaved aerated concrete blocks. Background Technology

[0002] Autoclaved aerated concrete (AAC) is typically made by mechanically mixing siliceous materials, calcareous materials, water, and various admixtures to form a slurry, which is then poured into molds, followed by static curing, autoclaving, and finally cutting and processing into blocks of a certain size.

[0003] Currently, autoclaved aerated concrete (AAC) blocks are typically pre-cut to specific dimensions before being transported to the construction site. However, in actual construction, non-standard blocks are sometimes required, such as for corner locations. This necessitates cutting standard blocks again to meet the usage requirements. However, convenient tools for cutting blocks are currently lacking on construction sites. Existing blocks are usually trimmed to the appropriate size using manual hammers and chisels, resulting in significant operational errors, poor surface smoothness, and waste. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide an autoclaved aerated concrete block cutting device that can further cut and process blocks on the construction site and is highly convenient to use, in order to address the above-mentioned technical deficiencies.

[0005] The technical solution adopted by this utility model is as follows: a cutting device for autoclaved aerated concrete blocks is provided, including clamps that are respectively arranged parallel to the left and right sides of the concrete block; an extension frame is fixed at the upper end of each clamp; the two extension frames are connected by a connector for adjusting the distance between the left and right clamps; a sliding rod is fixed vertically on the outside of the right clamp; a cutting control component is provided on the sliding rod. The cutting control assembly includes a mounting block that is slidably sleeved on a slide rod; a support shaft is fixed on the mounting block along the front-rear direction; a support frame is rotatably connected to the support shaft; an electric reciprocating saw is provided at the lower end of the support frame; the housing of the electric reciprocating saw is fixed to the lower end of the support frame; and the saw blade of the electric reciprocating saw extends from the front of the clamping plate.

[0006] To further optimize this technical solution, the connecting parts of the autoclaved aerated concrete block cutting equipment include a locking bolt rotatably connected to the left extension frame; the locking bolt is set in the left-right direction; the locking bolt thread passes through the right extension frame; a guide rod is fixed on the right extension frame in the left-right direction; the guide rod slides through the left extension frame.

[0007] To further optimize this technical solution, a positioning gear is fixedly fitted onto the support shaft of the autoclaved aerated concrete block cutting equipment; the positioning gear is located inside the support frame; an adjusting bolt is threaded through the upper end of the support frame and is set vertically; a toothed block is rotatably connected to the bottom end of the adjusting bolt; the toothed block slides vertically against the support frame; the toothed block meshes with the positioning gear.

[0008] To further optimize this technical solution, friction pads are fixed on the sides of the clamps of the autoclaved aerated concrete block cutting equipment that are close to each other.

[0009] The beneficial effects of this utility model are as follows: By adjusting the distance between the left and right clamping plates through the connecting parts, the two clamping plates can hold the block, achieving positioning between the clamping plates and the block, thus limiting the cutting position of the electric reciprocating saw on the block and ensuring precise cutting. The sliding mechanism between the mounting block and the vertical slide bar allows the saw blade to gradually penetrate the block during cutting, ensuring complete separation of the block. This equipment can be directly installed on the block to be cut at the construction site, occupying little space, is easy to carry, and is simple to operate, effectively suitable for applications requiring temporary cutting of single blocks during construction.

Detailed Implementation

[0012] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0013] like Figure 1 As shown, the autoclaved aerated concrete block cutting equipment includes clamping plates 1 respectively arranged parallel to the left and right sides of the concrete block; an extension frame 2 is fixed to the upper end of each clamping plate 1; the two extension frames 2 are connected by a connector for adjusting the distance between the left and right clamping plates 1; a slide rod 3 is fixed vertically to the outside of the right clamping plate 1; a cutting control component is provided on the slide rod 3. like Figure 1-2As shown, the cutting control assembly includes a mounting block 4 that is slidably sleeved on the slide rod 3; a support shaft 5 is fixed on the mounting block 4 along the front-rear direction; a support frame 6 is rotatably connected to the support shaft 5; an electric reciprocating saw 7 is provided at the lower end of the support frame 6; the housing 8 of the electric reciprocating saw 7 is fixed to the lower end of the support frame 6; and the saw blade 9 of the electric reciprocating saw 7 extends from the front of the clamping plate 1.

[0014] Place the device on the block to be cut. After the saw blade 9 of the electric reciprocating saw 7 locates the cutting position, adjust the connecting parts to clamp and fix the block with the two clamping plates 1, thus securing the device to the block. Start the electric reciprocating saw 7. With the reciprocating motion of its saw blade 9 and the sliding action of the mounting block 4 and the slide bar 3, the saw blade 9 of the electric reciprocating saw 7 can gradually cut the block from top to bottom, completing the cutting process.

[0015] During the above process, since the housing 8 of the electric reciprocating saw 7 is fixed to the lower end of the support frame 6, and the support frame 6 rotates on the support shaft 5, the saw blade 9 can move up and down during the cutting motion. In addition, the operator can control the saw blade 9 by hand, and the cutting angle of the saw blade 9 in the vertical plane can be flexibly changed, which enhances the flexibility of the cutting action. For example, if some parts are not easy to cut from the current angle, a different cutting angle can be used to cut them.

[0016] This equipment can be installed directly on the blocks that need to be cut at the construction site. It occupies little space, is easy to carry, and is simple to operate. It is effectively applicable to application scenarios where a single block needs to be cut temporarily during construction.

[0017] like Figure 1 As shown, the connector includes a locking bolt 10 rotatably connected to the left extension frame 2; the locking bolt 10 is arranged in the left-right direction; the locking bolt 10 is threaded through the right extension frame 2; a guide rod 11 is fixed on the right extension frame 2 in the left-right direction; the guide rod 11 slides through the left extension frame 2. By tightening the locking bolt 10, the distance between the two clamping plates 1 can be stably adjusted by the sliding of the extension frame 2 and the guide rod 11.

[0018] like Figure 1-2 As shown, a positioning gear 12 is fixedly sleeved on the support shaft 5; the positioning gear 12 is located inside the support sleeve 6; an adjusting bolt 13 is threaded through the upper end of the support sleeve 6 and is arranged vertically; a toothed block 14 is rotatably connected to the bottom end of the adjusting bolt 13; the toothed block 14 slides vertically with the support sleeve 6; the toothed block 14 meshes with the positioning gear 12.

[0019] When the adjusting bolt 13 is turned, the toothed block 14 is driven to mesh with the positioning gear 12, and the support sleeve 6 and the support shaft 5 are relatively positioned. At this time, the electric reciprocating saw 7 can only move up and down, and the cutting angle on the vertical plane is locked to meet the need for stable cutting from one direction.

[0020] like Figure 1 As shown, friction pads 15 are fixed on both sides of the clamping plate 1 that are close to each other. The friction pads 15 increase the friction between the clamping plate 1 and the block, improve the clamping stability, and also buffer and protect the surface of the block to avoid clamping damage.
