Detailed ways

Referring to Fig. 1 and Fig. 2, the utility model provides a grab bucket of a material transfer trolley, including a grab base 1, a connecting column 2 fixed on the upper end surface of the grab base 1, and a Connection block 3 on the end face. The grab base 1 can provide a platform to facilitate the installation of the grab mechanism. At the same time, it can also install multiple connecting columns 2, and use the connecting columns 2 to connect with other equipment such as hoisting equipment in the workshop, so that the driving grab can be operated It is more stable and reliable, and it is more stable than chain connection.

A grab mechanism is arranged on the connecting block 3 , and the grab mechanism includes two grab buckets 4 , a support arm 5 , hydraulic components and a movable block 6 . The movable support arm 5 is hinged between each grab 4 and the connecting block 3; the inner sides of the two grabs 4 are respectively hinged on both sides of the movable block 6; the motor of the hydraulic assembly is built in the connecting block 3, and the expansion and contraction of the hydraulic assembly The rod 7 is connected with the movable block 6 to drive the movable block 6 to move.

As shown in Figure 1, when the motor of the hydraulic assembly starts to drive the telescopic rod 7 to move downward, since the inner sides of the two grab buckets 4 are hinged on both sides of the movable block 6, the movable block 6 will move downwards under force. It will drive the grab bucket 4 to overturn toward the outside, thereby causing the grab bucket 4 to be opened. After the material has been grabbed, the telescopic rod is recovered, and the movable block 6 moves up, so that the grab bucket 4 can also be turned inside. Since the grab bucket 4 is generally capsule-shaped or similar to a semi-ellipsoid, the utility model preferably grabs a bucket It is in the shape of a semi-ellipsoid and has a material-holding space inside; therefore, it can be closed after being turned inside out, realizing the grasping of materials.

Referring to FIG. 2 , a movable water baffle is also provided on the movable block 6 ; the water baffle includes a connecting rod 8 connected with the movable block 6 and a water receiving pan 9 fixed on the connecting rod 8 . Before grabbing the material, the operator can manually or otherwise turn the water baffle upwards to the top of one grab bucket 4 on the rack, and then lower the water baffle after the grab bucket 4 is closed, so that it slides down until the two grab buckets are closed Right below the gap at the center, the moisture sauce leaking along the gap can be collected directly.

As one of the optimized embodiments of the present invention, four connecting columns 2 are arranged on the grab base 1, and the four connecting columns 2 are respectively arranged at four corners, so that the grab 4 can run more smoothly.

As one of the optimized embodiments of the present utility model, two support arms 5 are hinged on the grab bucket 4; end. The outer side of the connecting block 3 is provided with a hanging ear 10 with a pin hole, and the outer side of the grab bucket 4 is provided with a hanging ear 11 with a pin hole; both ends of the support arm 5 are provided with a movable pin shaft, and the movable pin shaft is inserted into the pin hole to realize Live articulation.

As one of the optimized embodiments of the present invention, a first pin shaft 12 is provided at the joint between the movable block 6 and the grab bucket 4, and a pin hole matching the first pin shaft is provided inside the grab bucket.

In order to facilitate the up and down movement of the water baffle, two methods can be adopted. For example, when the water baffle is manually lifted, a second pin 13 can be set at both ends of the movable block 6, and the second pin 13 is connected to the connecting rod 8. The pin-hole cooperation realizes the connection between the connecting rod 8 and the movable block 6, and the operator can manually turn the water retaining plate over or below the grab bucket to receive water. For example, it is also possible to use an electric method to set a geared motor inside the movable block, and the shaft of the geared motor is vertically connected to the tail end of the connecting rod of the water shield; the shaft of the geared motor drives the connecting rod to move in an arc, and the operator can Control the rotation of the geared motor to adjust the position of the water baffle, which is more conducive to automation.

Although the specific implementation of the utility model has been described in detail in conjunction with the accompanying drawings, it should not be understood as limiting the scope of protection of this patent. Within the scope described in the claims, various modifications and deformations that can be made by those skilled in the art without creative efforts still belong to the protection scope of this patent.
