Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically a mobile cart for laying flat cement slabs. Background Technology

[0002] Cement board, as the name suggests, is a type of building slab made primarily from cement. It's a building product somewhere between gypsum board and natural stone, allowing for free cutting, drilling, and carving. Its superior fire resistance, water resistance, corrosion resistance, insect resistance, and sound insulation compared to gypsum board and wood panels, along with its significantly lower price than natural stone, has made it a widely used building material in the construction industry. Cement boards are available in both precast and cast-in-place forms.

[0003] Cement boards have many uses, most commonly in the decoration and construction industry. However, after the precast cement boards reach the required strength, they need to be lifted from the ground and laid vertically to continue drying. Cement boards are heavy, and during transport, they are prone to cracking or posing a safety hazard to workers, delaying handling and stacking, significantly increasing labor costs, and reducing work efficiency.

[0028] Figures 1 to 6 This invention illustrates one embodiment of a flat-lay cement slab mobile cart.

[0029] like Figures 1 to 3 The illustrated mobile trolley for laying flat cement slabs includes a mobile chassis 1, a trolley frame, a gripping device, and a rotational anti-detachment lock. The trolley frame is mounted on the mobile chassis, and the gripping device is located at the front end of the trolley frame. The mobile chassis enables movement, the trolley frame controls the movement direction of the entire device and the clamping and unlocking of the cement slab, the gripping device clamps the cement slab and drives the cement slab to move with the mobile chassis.

[0030] The mobile chassis 1 of this device is equipped with a pair of moving wheels 11, which are connected by axle 12.

[0031] The trolley frame 2 of this device consists of two parallel beams 21. The lower part of the beams 21 is fixed to the axle 12 of the movable chassis, and the rear end of the beams 21 consists of two inclined beams 22. The beams 21 and the inclined beams 22 are connected at an obtuse angle.

[0032] The gripping device includes two gripping frames arranged vertically and hinged together at their rear ends. The lower gripping frame is fixed to the front end of the trolley frame beam. The lower gripping frame has a bottom support plate, and the upper gripping frame has a pressure plate at its top. The upper gripping frame has a rotating anti-detachment lock in the middle. The rotating anti-detachment lock is U-shaped with its opening facing forward. One side of the vertical part is hinged to the rear end of the pressure plate of the upper gripping frame. The width of the U-shaped rotating anti-detachment lock is greater than the thickness of the cement board to be gripped. The free end of the rotating anti-detachment lock is connected to an unlocking rope 41, and the other end of the unlocking rope 41 is connected to the operating handle for the operator to pull.

[0033] The upper gripper frame is rotatable and has a hinged lug at the lower rear end. The lower gripper frame also has a hinged lug at the lower rear end. The hinged lugs of the upper and lower gripper frames are connected by pins, and the upper gripper frame can swing forward by passing through the middle of the lower gripper frame.

[0034] The lower gripper frame 32 is fixed to the front end of the vehicle beam 21, and the hinge shaft on the gripper frame is parallel to the wheel axle 12.

[0035] The lower gripping frame 32 and the upper gripping frame are hinged to the rear ear plate 2 in pairs. The lower gripping frame 32 is a U-shaped frame with the opening facing upwards. The support plate is located at the lower front end of the U-shaped frame. The upper gripping frame is a U-shaped frame with the opening facing downwards. The pressure plate is located at the top front end of the U-shaped frame. The pressure plate and the support plate work together to support the width side of the cement board.

[0036] The rotating anti-loosening lock 4 has a locking pull ring 42 that is positioned upwards and backwards. The locking pull ring 42 is connected to the unlocking rope 41. The vehicle beam 21 has a connecting crossbar 23 at the inclined beam 22. The other end of the unlocking rope 41 is connected to the connecting crossbar 23.

[0037] Push the plate device forward to the cement slab, so that the support plate contacts the side surface of the cement slab. Erect the trolley frame, swing the upper gripping frame forward, and swing the pressure plate to the other side surface of the cement slab. Pull the trolley frame back, and with the bottom of the lower gripping frame as the center, drive the lower gripping frame and the upper gripping frame to swing backward. Due to the weight of the upper gripping frame, it will descend and press down on the side surface of the cement slab. At this time, the support plate and the pressure plate clamp the cement slab.

[0038] Continue pulling the trolley frame backward. Rotate the anti-slip lock. Due to its own weight, it will swing forward and fall, and swing to the front side of the cement board with the hinge axis as the center. This will prevent the cement board from slipping forward due to insufficient clamping force of the pressure plate and the support plate caused by its own weight.

[0039] The upper and lower gripping frames of this device have multiple hinged lugs at different heights. Each pair of hinged lugs at each height is connected to the upper and lower gripping frames by a pin. The distance between the pressure plate and the support plate connected to the upper and lower gripping frames can be adjusted by the hinged lugs to grip and move cement slabs of different widths.

[0040] When releasing the cement slab while it is standing upright, move the trolley frame to the placement point. With the lower edge of the cement slab in contact with the ground, lift the rear end of the trolley frame. As the cement slab approaches the vertical support surface, pull the unlocking rope 41. Due to the weight of the cement slab, the pressure plate and support plate release the cement slab, causing it to slide down from its high position and contact the vertical support surface. During this process, the cement slab slides a short distance due to its own weight, preventing damage to its structure.

[0041] The beams and axles of this device are welded from steel pipes, which are not only strong and reliable, but also lightweight, hard, corrosion-resistant, abrasion-resistant, and rust-resistant, allowing for long-term use.

[0042] The diagonal beam of the cart frame is equipped with hand guards made of rubber. Rubber is not only resistant to high temperatures, corrosion, water, and friction, but its friction against the hand also allows for effective changes in the direction and angle of the cart frame. The hand guards feature symmetrical hand grip recesses, ergonomically designed for a more comfortable and secure fit. The unlocking rope is made of nylon, which is strong, durable, and reliable.
