[0005] In order to achieve the above-mentioned purpose, the utility model specifically adopts the following technical solutions:

[0006] An adjustable parallel four-link car pressing device for a car tipping machine comprises: a support one, a support two, a support three, a car pressing arm, a connecting rod, a connecting plate, a movable pressure head and a car pressing oil cylinder; the support one is fixedly mounted on a car support beam, the support two and the support three are both fixedly mounted on the support one, the support two, the car pressing arm and the movable pressure head are hingedly connected in sequence, the support three, the connecting rod and the connecting plate are hingedly connected in sequence, the connecting plate is fixedly connected to the movable pressure head, and the car pressing oil cylinder is installed between the car support beam and the car pressing arm.

[0007] Preferably, the number of support three and connecting rods in the four-link car pressing device are both two, one end of the two connecting rods are hinged to the two support threes, and the other ends of the two connecting rods are hinged to the connecting plate, the support two is located between the two support threes, and the car pressing arm is located between the two connecting rods.

[0008] Preferably, both ends of the car pressing oil cylinder are hingedly connected to the car support beam and the car pressing arm respectively through mounting seats.

[0009] Preferably, a rubber buffer plate is provided on the outer side of the movable pressure head, and the rubber buffer plate is in contact with the upper edge of the open car.

[0010] Preferably, there are multiple four-link car pressing devices, and the multiple four-link car pressing devices are distributed in pairs in mirror symmetry with the open car as the center.

[0011] The beneficial effects of the utility model are as follows: a four-link mechanism is formed by a car pressing arm, three supports, a connecting rod, a connecting plate and a movable pressing head. When the car pressing cylinder drives the car pressing arm to do a pitching movement, the four-link mechanism can keep the movable pressing head in a horizontal state and in contact with the upper edge of the side wall of the open car according to different car models, thereby achieving the effect of balanced car pressing force and reliable car clamping. At the same time, it is suitable for various open car models and expands the application range of the car pressing mechanism of the tipping machine. BRIEF DESCRIPTION OF THE DRAWINGS
