Description

Technical Field

[0001] The invention relates to the technical field of laying flexible concrete composite mats, in particular to a special laying device for a reel-type flexible concrete composite mat. Background Art

[0002] Flexible concrete composite mat, commonly known as cement blanket, is a new type of environmentally friendly ecological composite waterproof and anti-seepage material. It consists of a water-absorbing protective layer, a concrete filling layer (including a reinforced reinforcement layer) and a moisturizing layer. It uses a needle-punched fiber skeleton or sutured composite together to form a flexible concrete composite mat.

[0003] Flexible concrete composite mats are widely used in highway maintenance, water conservancy projects, river protection, and other fields. However, the laying of flexible concrete composite mats is often done manually, requiring manual unfolding of the composite mat. This is not only inefficient, but also labor-intensive and prone to errors. In addition, manual laying cannot ensure the uniformity and continuity of the composite mat, thus affecting the laying quality. Summary of the Invention

[0006] Preferably, a tool mounting seat for mounting a shearing knife is provided at the front end of the first translation mechanism, and the shearing knife is detachably connected to the tool mounting seat.

[0007] Preferably, a connector is provided at the rear end of the shearing knife, a connector slot adapted to the connector is provided at the front end of the tool mounting seat, and a locking mechanism is provided between the connector and the tool mounting seat.

[0008] Preferably, the locking mechanism includes a limit groove arranged at the top of the connector and a mounting cavity arranged in the tool mounting seat. The mounting cavity is located above the plug-in groove and is connected to the plug-in groove. A slider is provided in the mounting cavity, and a limit block corresponding to the limit groove is provided at the bottom of the slider. A pull rod is provided on the top, and the top end of the pull rod extends upward from the tool mounting seat. A spring is provided in the mounting cavity, and the bottom end of the spring abuts against the slider, and the top end abuts against the top wall of the mounting cavity.

[0009] Preferably, the frame is provided with a brake mechanism for locking the pressure roller, and the brake mechanism includes an arc-shaped locking plate adapted to the pressure roller and an adjusting mechanism for adjusting the distance between the arc-shaped locking plate and the brake mechanism.

[0010] Preferably, the adjustment mechanism includes an adjustment box arranged between the two pressure rollers and a second translation mechanism arranged in the adjustment box. The adjustment box is fixed to the bottom of the frame. The arc-shaped locking plate is located on the rear side of the pressure roller at the front end of the frame. The arc-shaped locking plate is driven to move forward and backward by the second translation mechanism. An anti-slip pad is provided on the inner side of the arc-shaped locking plate.

[0011] Preferably, a handlebar is provided at the front end of the top of the frame.

[0012] Preferably, a power supply box is provided on the top of the frame, and a battery and a support base for providing support for the battery are provided in the power supply box, and the battery and the support base are detachably connected.

[0013] Preferably, an insert block is provided at the bottom of the battery, a slot adapted to the insert block is provided at the top of the support seat, and a locking structure is provided between the insert block and the support seat.

[0014] Preferably, guide rails are provided on both the left and right sides of the frame, and the end of the central axis of the pressure roller is inserted into the guide rail and is slidably connected to the guide rail.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. The present invention adopts a scroll-type design, winds the flexible concrete composite mat on the winding roller, and then smoothly unfolds the composite mat by driving the winding roller to rotate through a driving device, and drives the entire paving device to move by rotating the pressure roller. While the paving device moves, the pressure roller at the rear end compacts the flexible concrete composite mat laid on the ground, so that the flexible concrete composite mat fits tightly to the ground or slope, ensuring a continuous and uniform paving process and improving construction efficiency.

[0016] 2. The present invention drives the shear blade to translate through the first translation mechanism, and is used to shear flexible concrete composite mats. Compared with manual operation, it can greatly improve production efficiency, especially in situations where a large number of flexible concrete composite mats need to be sheared. The first translation mechanism can provide a stable and precise driving force to ensure that the force and position of each shear are consistent, thereby ensuring the stability and consistency of the shearing quality and reducing errors caused by human factors. The automated shearing process does not require human participation, which greatly reduces the physical burden of the operator and avoids physical fatigue and occupational diseases that may be caused by long-term repetitive labor. Using the first translation mechanism for shearing operations avoids direct contact between operators and dangerous parts such as shear blades, effectively reducing the risk of industrial accidents and improving workplace safety.

[0017] 3. The shear blades of this invention feature a detachable connection, making them easier to inspect, clean, and repair. This is crucial for maintaining the blade's sharpness, extending its lifespan, and ensuring cutting quality. If the shear blades become worn or damaged from prolonged use, the detachable design allows for quick replacement without the need for complex or time-consuming disassembly of the entire unit. This relatively simple and quick process reduces maintenance time and allows the equipment to be restored to working order more quickly, thereby improving overall efficiency.

[0018] 4. The present invention is also provided with a brake mechanism to achieve braking by locking the pressure roller at the front end. BRIEF DESCRIPTION OF THE DRAWINGS

The first translation mechanism 51 can be an electric push rod, a hydraulic cylinder, etc. A support is provided at the rear end of the first translation mechanism 51. The bottom end of the support can be fixed to the frame 1 by screws or directly welded to the frame 1.

[0029] The frame 1 is vertically provided with a through hole adapted to the flexible concrete composite pad 4. After the flexible concrete composite pad 4 passes between the shearing knife 5 and the shearing seat 33, it enters the bottom of the frame 1 through the through hole and is then compacted by the pressure roller 2 at the rear end of the frame 1.

[0030] During use, the driving device 32 can drive the winding roller 31 to rotate, and then the rotating winding roller 31 can smoothly unfold the flexible concrete composite mat 4. During laying, the pressing roller 2 enables the flexible concrete composite mat 4 to fit closely to the slope surface; when the flexible concrete composite mat 4 needs to be sheared, the first translation mechanism 51 can drive the shear knife 5 to move laterally, thereby shearing the flexible concrete composite mat 4.
