Description

Technical Field

[0001] This utility model relates to the construction industry, specifically a precast concrete slab trimming device. Background Technology

[0002] Precast slabs are modules or panels used in engineering projects. Because they are precast concrete components manufactured and processed in a prefabrication yard and then transported directly to the construction site for installation, they are called precast slabs. To make precast slabs, a hollow model is first made by nailing wooden boards together. Reinforcing steel bars are then placed in the hollow parts of the model, and cement is poured into the hollow parts. After drying, the wooden boards are removed, leaving the precast slab.

[0003] Due to the inherent properties of concrete, precast slabs often require trimming after production. In traditional trimming operations, the trimming direction is often observed by eye, which inevitably leads to operational errors and damage to the concrete slabs. Utility Model Content

[0004] The purpose of this invention is to provide a precast concrete slab trimming device to solve the above-mentioned problems.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

A vertical frame is fixed on the support frame, and a laser emitter is mounted on the vertical frame. The trimming mechanism includes a saw blade and a driver for driving the saw blade to rotate. The upper part of the saw blade extends out of a strip-shaped hole opened on the support frame and can move back and forth along the direction of the strip-shaped hole. The strip-shaped hole is arranged parallel to the laser beam emitted by the laser emitter.

Detailed Implementation

[0022] The following embodiments will be described in detail with reference to the accompanying drawings. In the drawings and description, similar or identical parts are referred to by the same reference numerals. Furthermore, in practical applications, the shape, thickness, or height of each component may be enlarged or reduced. The embodiments listed in this utility model are merely illustrative and not intended to limit the scope of the utility model. Any obvious modifications or alterations made to this utility model do not depart from its spirit and scope.

[0023] Please see Figure 1 In one embodiment of this utility model, a precast concrete slab trimming device includes a support frame 10, a placement platform 20 for placing the concrete slab, and a trimming mechanism 30 for trimming the concrete slab. In use, the concrete slab is placed on the placement platform 20, and the trimming mechanism 30 trims the concrete slab.

[0024] A stand 101 is fixed on the support frame 10, and a laser emitter 60 is mounted on the stand 101. The trimming mechanism 30 includes a saw blade 301 and a driver 302 for driving the saw blade 301 to rotate. The upper part of the saw blade 301 extends out of the strip hole 102 opened on the support frame 10 and can move back and forth along the direction of the strip hole 102. The strip hole 102 is arranged parallel to the laser beam emitted by the laser emitter 60. In use, the laser beam hits the concrete slab, and the workers can perform trimming operations by being guided by the laser beam to avoid deviation, thereby greatly reducing the possibility of operational errors.

[0025] Please see Figure 2-3 In one embodiment of this utility model, the trimming mechanism 30 further includes a movable mounting base 303, and the driver 302 is mounted on the movable mounting base 303. The movable mounting base 303 is slidably engaged in the slide groove 103 opened in the support frame 10. The slide groove 103 is arranged parallel to the strip hole 102. In specific operation, the driver 302 drives the saw blade 301 to rotate, and then pushes the movable mounting base 303 to move along the slide groove 103 to perform the trimming operation.

[0026] Furthermore, in this embodiment, an extension rod 304 is fixed to the outside of the movable mounting base 303. The extension rod 304 extends out of the support frame 10 and is connected to a handle 305, thereby facilitating pushing and pulling.

[0027] Please see Figure 1 and Figure 4 In one embodiment of this utility model, the placement platform 20 is rotatably connected to the support frame 10, thereby adjusting the angle of the concrete slab.

[0028] Furthermore, a turntable 40 is coaxially fixed to the placement platform 20. The turntable 40 is located below the platform of the support frame 10 and its outer periphery extends out of the support frame 10. Thus, the placement platform 20 can be rotated by the turntable 40. At the same time, since the turntable 40 is located below the platform of the support frame 10, the operation will not be interfered with by the concrete slab above the platform, making it more convenient.

[0029] Furthermore, the turntable 40 is provided with a slot 401, and the slot 401 is equipped with a pin 402. The pin 402 passes through the table surface of the support frame 10. When no angle adjustment is required, the rotation of the turntable 40 can be locked by the cooperation of the slot 401 and the pin 402.

[0030] Please see Figure 4 In one embodiment of this utility model, a fixing mechanism 50 for fixing the concrete slab is also provided on one side of the placement platform 20, so as to avoid displacement during the trimming process.

[0031] Furthermore, in this embodiment, the fixing mechanism 50 includes a fixing frame 501 and a locking bolt 502. The fixing frame 501 is fixed on the placement platform 20, and the locking bolt 502 is threadedly connected to the fixing frame 501. A pressure plate 503 is rotatably connected to the bottom of the locking bolt 502. The pressure plate 503 is slidably connected to the fixing frame 501 through a guide rod 504. After the concrete slab is placed on the placement platform 20, the locking bolt 502 is rotated to drive the pressure plate 503 to move downward, thereby fixing the concrete slab.

[0032] The working principle of this utility model is as follows:

[0033] The precast concrete slab trimming device in this embodiment of the invention, by setting up a laser emitter 60 that emits a laser beam aligned with the strip hole 102 and a saw blade 301 that can move back and forth along the strip hole 102, allows workers to trim under the guidance of the laser beam, avoiding deviation and greatly reducing the possibility of errors and damage. The rotating placement platform 20 allows for adjustment of the angle of the concrete slab, making it more flexible to use, and the turntable 40 makes operation very convenient. The fixing mechanism 50 can fix the concrete slab to be trimmed, preventing it from shifting during the trimming process.
