Description

A floating gripper for self-adaptive bricklaying stacks

technical field

The utility model relates to the field of clamping devices, in particular to a floating clamping claw for self-adaptive bricklaying stacks.

Background technique

At present, more and more manufacturers use fly ash, quicklime, gravel, sand and other raw materials to make building bricks. Since the finished bricks produced are generally stacked on autoclaved trolleys, the finished bricks placed on each autoclaved trolley The quantity and placement method are exactly the same. In addition, most brick factories have a large output (generally 100,000 to 150,000 per day), and the finished bricks are placed on autoclaved trolleys, requiring too many autoclaved trolleys, which increases production costs. The finished bricks need to be unloaded from the autoclave trolley.

Chinese patent CN201210296238.4 discloses a clamping device and a brick holding machine using the device. The clamping device includes a hanger and a hanger hinged on the top of the hanger that can swing back and forth. The hanger is equipped with a clamp. The hanger includes a hanger body hinged on the hanger and a sliding seat that guides and moves along the left and right directions and is assembled on the hanger, and the clamp is assembled on the sliding seat. Although this invention realizes the left and right movement of the clamp, and then can adjust the left and right deviation between the clamp and the brick stack loading and unloading position, making the loading and unloading operation more convenient, but the clamping device of this invention cannot adapt to the shape of the brick stack, and can only be operated by a power vehicle Manual adjustment by the operator reduces the efficiency of loading and unloading.

Utility model content

The purpose of this utility model is to provide a floating clamping claw for self-adaptive bricklaying, which is used to solve the problem that the clamping device of the bricklaying machine in the prior art cannot adapt to the shape of the bricklaying pile, and can only be manually adjusted by the operator of the power car , A problem that affects loading and unloading efficiency. In the utility model, by setting the first limit block and the first clamping mechanism for clamping or loosening the first limit block, the clamping device of the brick holding machine can self-adaptively clamp the floating direction of the brick stack without relying on The power trolley operator manually adjusts the effect of the clamping device.

The utility model is realized through the following technical solutions:

A floating gripper for self-adaptive bricklaying stacks, comprising an L-shaped hanger connected in sequence, a floating device, and a clamping device; the floating device includes a base connected to the hanger, and a linear floating plate slidably arranged on the base , Rotate the circular rotary floating plate which is arranged on the linear floating plate and connected with the clamping device; the sliding direction of the linear floating plate is parallel to the clamping direction of the clamping device, and the linear floating plate is parallel to the side of the sliding direction of the linear floating plate It has a first limit block; the base is provided with a first clamping mechanism for clamping and releasing the first limit block. The hanger is connected to the forklift or the crane, and is used to connect the clamping device and the floating device to the forklift or the crane. The clamping device is used for clamping the stack of bricks. The existing technology is adopted. For example, the clamp in a clamping device disclosed in Chinese patent CN201210296238.4: it includes two clamping arms arranged opposite to each other. The lower ends respectively have clamping parts opposite to each other, and the two clamping parts are provided with oppositely disposed polyurethane plates for clamping and matching with finished bricks. The sliding direction of the linear floating plate is parallel to the clamping direction of the clamping device so that the clamping device floats in the clamping direction, so that the clamping device can float left and right or forward and backward during the process of clamping the brick stack. The principle of floating is: when the clamping center of the clamping device deviates from the center of the brick-laying pile, in the process of clamping the clamping device to the brick-laying pile, there must be a clamping arm that first touches the brick-laying pile. The device continues to clamp the brick-laying pile. Since the clamping device can float along the clamping direction, under the reaction force of the brick-laying pile, the clamping arm that first contacts the brick-laying pile drives the entire clamping device along the opposite direction of the clamping direction. Move until another clamping arm contacts the brick pile and clamps the brick pile, at this moment, the center of the brick pile coincides with the clamping center of the clamping device. Due to the gravity of the clamping device, forklift or driving vibration and other factors, the clamping device may stay at a limit position in the sliding direction of the linear floating plate, resulting in no floating amount in this direction and losing the floating effect. Therefore, the first clamping mechanism is set. , before the clamping device is clamped, the first limit block is clamped, so that the two limit positions of the clamping device and the linear floating plate in the sliding direction have a floating amount, and the clamping device is aligned with the brick stack. When clamping, the first clamping mechanism releases the first limit block to realize floating. The first clamping mechanism adopts prior art, such as jaw cylinder, rack-and-pinion mechanism, etc. Since the jaw cylinder and rack-and-pinion mechanism are prior art in the field, no detailed description will be given here.

There is a floating amount at the two limit positions. When the clamping device aligns with the brick pile and starts clamping, the second clamping mechanism releases the second limit block to realize floating.

When the two oil cylinders all stretched out the piston rods, the push block clamped the first limit block. When both oil cylinders retract the piston rods, the push block releases the first limit block to realize floating. The stroke of the piston rod of the oil cylinder is the floating amount of the first limit block and the linear floating plate. The symmetrical arrangement means that the two linear mechanisms are arranged on both sides of the first limiting block, and are arranged symmetrically with respect to the first limiting block. The linear mechanism can also be a linear motion mechanism in the prior art in the field such as a linear cylinder, a linear motor, and a motor lead screw.
