Description

A brick moving machine with self-locking jaws

technical field

The utility model relates to the field of brick-laying and stacking brick-holding machines, in particular to a brick-moving machine with self-locking jaws.

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. There are two ways to handle the finished bricks unloaded from the autoclaved trolley: 1. Load them directly from the autoclaved trolley to the car, and then transport them to the construction site by car; 2. Put them in a dedicated storage site for stacking and storage. Whether it is direct transportation or stacking, loading and unloading operations are required, and most manufacturers use manual loading and unloading methods, which is not only labor-intensive and time-consuming, but also labor-intensive for workers, and bumps during loading or unloading bricks are likely to cause The edges and corners of the finished bricks are off, which affects the appearance quality of the finished bricks.

Chinese patent CN201620392181.1 discloses a brick holding machine fixture for forklifts and loaders, including a back plate and movable plates connected to the left and right ends of the back plate. There are guide sleeves and oil cylinders arranged horizontally between the plates, and the guide sleeves are welded between two fixed plates, and the through holes for connecting the guide sleeves are arranged on the fixed plates, and the bottom end of the oil cylinder is fixed on one side On the fixed plate, the support rod of the oil cylinder passes through the fixed plate on the other side to be connected with the movable plate, and the two movable plates arranged on the left and right are provided with guide columns corresponding to the guide sleeves. Although the patent is simple to operate, it does not need manual handling, and realizes mechanization, and can transport hundreds of thousands of bricks at one time, which improves work efficiency; however, the clamps of this patent cannot be self-locking, and hydraulic cylinders are required to clamp the brick stack all the time. When the system breaks down, the oil cylinder will unclamp the fixing plate, that is, the clamping arm of the present utility model, and danger will occur.

Utility model content

The purpose of the utility model is to provide a brick moving machine with self-locking jaws, which is used to solve the problem in the prior art that the clamping device of the brick moving machine cannot be self-locking. The utility model is provided with a clamping arm, a power arm, a connecting arm, and a driving device. When it is necessary to clamp the bricklaying stack, the driving device drives the power arm to rotate so that the clamping arm and the power arm are articulated at the hinge point, the power arm and the connecting arm. The hinge point of the hinge, the base and the hinge point of the connecting arm are in a straight line to realize the self-locking effect of the clamping arm.

The utility model is realized through the following technical solutions:

A brick moving machine with self-locking jaws, comprising a power car, an L-shaped hanger installed on the front end of the power car, a floating device installed on the top of the L-shaped hanger, and a clamping device installed at the bottom of the floating device; The clamping device includes a base fixedly connected to the bottom of the floating device and two clamping mechanisms with the same structure and relatively arranged on the left and right sides of the base. The clamping mechanism includes an L-shaped clamping arm, an L-shaped power arm, a connecting Arm, driving device; the two ends of the connecting arm are respectively hinged with the base and the power arm; the two ends of the short side of the power arm are respectively hinged with the clamping arm and the connecting arm; Hinged; the driving device drives the power arm to rotate to realize the clamping and loosening of the clamping arm. The power vehicle is a forklift or a crane in the prior art, and the L-shaped hanger is used to connect the clamping device and the power vehicle, which is prior art in this field. The floating device adopts the prior art, such as a clamping device disclosed in Chinese patent CN201210296238.4 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, and 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. The driving device drives the power arm to rotate so as to drive the clamping arm to rotate around the hinge point where the clamping arm is hinged with the base, so as to realize the release and clamping of the clamping arm. When the driving device drives the power arm to rotate so that the hinge point of the clamping arm and the power arm, the hinge point of the power arm and the connecting arm, and the hinge point of the base and the connecting arm are in a straight line, the clamping arm clamps the brick At this time, the clamping mechanism is at the dead point, so as to realize the self-locking of the clamping mechanism. The drive device can adopt existing technologies such as motors and oil cylinders, and the specific structure is common knowledge in the art, and will not be described here.

Preferably, the drive device includes a first oil cylinder fixedly connected to the base, a drive block fixedly connected to the piston rod of the first oil cylinder, and a drive pin connected to the drive block; the long side of the power arm is two One end of the hinge point is provided with a waist-shaped hole; the driving pin is located in the waist-shaped hole. Because the waist-shaped hole is set on the power arm, when the first oil cylinder stretches out or retracts, because the driving pin can move in the waist-shaped hole, the first oil cylinder can drive the power arm to rotate without being hinged.

Preferably, the floating device includes a base plate connected to the hanger, and a linear floating plate slidingly arranged on the base plate; the sliding direction of the linear floating plate is parallel to the clamping direction of the clamping mechanism, and the linear floating plate slides parallel to the linear floating plate The side of the direction has a first limit block; the bottom plate is provided with a first clamping mechanism for clamping and releasing the first limit block. The sliding direction of the linear floating plate is parallel to the clamping direction of the clamping mechanism to make the clamping mechanism float in the clamping direction, so that the clamping mechanism can float in the clamping direction during the process of clamping the brick stack. The principle of floating is: when the clamping center of the clamping mechanism deviates from the center of the brick-laying stack, in the process of clamping the brick-laying stack, there must be a clamping arm that first touches the brick-laying stack. The mechanism continues to clamp the brick pile. Since the clamping mechanism can float along the clamping direction, under the reaction force of the brick pile, the clamping arm that first contacts the brick pile drives the entire clamping mechanism to move in the opposite direction of the clamping direction. Move until the other 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 mechanism. Due to the gravity of the clamping mechanism, forklift or driving vibration and other factors, the clamping mechanism 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 mechanism is clamped, the first limit block is clamped, so that the two limit positions of the clamping mechanism and the linear floating plate in the sliding direction have a floating amount, and when the clamping mechanism 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.

Preferably, the first clamping mechanism is two linear mechanisms with the same structure and symmetrically arranged on both sides of the first limit block parallel to the sliding direction of the linear floating plate; the linear mechanism includes an oil cylinder fixedly connected to the bottom plate plate, the second oil cylinder detachably connected to the oil cylinder mounting plate, and the push block fixedly connected with the piston rod of the second oil cylinder to push the movement of the first limit block. When the two second oil cylinders stretch out the piston rods, the push block clamps the first limit block. When the two second 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 second 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.

Preferably, the oil cylinder mounting plate is slidably provided with a guide shaft connected to the push block. The guide shaft is set so that the push block cannot rotate around the piston rod of the second oil cylinder, and the piston rod of the second oil cylinder can be prevented from being subjected to eccentric axial force, thereby improving the service life of the second oil cylinder.

Preferably, a linear guide rail is detachably connected to the bottom plate, and a slider detachably connected to the linear floating plate is slid on the linear guide rail. The linear guide rail is a prior art in this field, so the specific structure will not be described here. The linear guide rail is arranged to reduce the motion resistance of the linear floating plate, thereby reducing the driving force of the first clamping mechanism and saving energy.

Compared with the prior art, the utility model has the following advantages and beneficial effects:

(1) The utility model is provided with a clamping arm, a power arm, a connecting arm, and a driving device.

The hinge point hinged with the connecting arm, the base and the hinged point hinged with the connecting arm are in a straight line, realizing the self-locking effect of the clamping arm;

(2) The utility model sets the waist-shaped hole on the power arm, so that the first oil cylinder can be directly fixed on the base to drive the power arm, and realize the effect of convenient pipe arrangement of the first oil cylinder;

(3) The utility model realizes that the clamping device of the brick-holding machine can self-adaptively clamp the floating in the direction of the brick-laying stack by setting the first limit block and the first clamping mechanism that clamps or loosens the first limit block.
