[0028] Example 1

[0029] The hydraulic cylinder dump truck provided in this embodiment includes a frame 1, on which a carriage 2 or a tank is arranged, that is, the tank or the carriage 2 can be used to transport goods, and the rear of the carriage 2 or the tank is rotatably connected to the frame 1, and the rotatable connection is any rotatable connection method of a rear dump truck and any other prior art of rotatable connection. A push plate is arranged in the carriage 2 or the tank, and a mounting seat 8 is arranged at the front of the frame 1, and a hydraulic cylinder 3 is arranged between the mounting seat 8 and the push plate; in normal use, the push plate can slide forward and backward in the carriage 2 or the tank, and when the hydraulic cylinder 3 is in operation, the hydraulic cylinder 3 drives the push plate to move in the carriage 2 or the tank, thereby realizing rear push unloading. Of course, when it is more convenient to unload by flipping backward, or when it is necessary to tilt the carriage 2 or tank body while pushing backward for unloading, the hydraulic cylinder 3 extends upward in the direction of the push plate, and the hydraulic cylinder 3 is rotated to connect the middle and upper part of the push plate, so that the hydraulic cylinder 3 can drive the carriage 2 or tank body to flip backward as a whole by pushing the push plate, that is, the front part is lifted, and the carriage 2 or tank body is flipped backward by the rotation connection at the rear part. When it is necessary to push the carriage 2 or tank body to flip backward by the hydraulic cylinder 3, the push plate should be prohibited from moving, so that the driving force of the hydraulic cylinder 3 pushes the carriage 2 or tank body to flip backward. A locking device is also provided between the carriage 2 or tank body and the push plate, which temporarily fixes the push plate and is used to lock and connect the push plate and the carriage 2 or tank body so that the push plate cannot move forward and backward in the carriage 2 or tank body. The locking of the locking device should be a detachable locking, that is, the locking state can be changed, and locking is required when flipping backward is required, and unlocking is required when locking is not required. The locking device can be any existing locking method such as a card slot, a lock, a tether, etc.

[0030] Compared with conventional hydraulic cylinder dump trucks with push plates, the above hydraulic cylinder dump truck can push the push plate to move forward and backward in the carriage 2 or tank body through the hydraulic cylinder 3 to realize the unloading function. However, when it is necessary to unload the cargo by flipping over, the push plate can be fixed by a locking device so that the push plate cannot move forward and backward in the carriage 2 or tank body. At this time, the hydraulic cylinder 3 extending obliquely upward pushes the push plate to move upward, thereby pushing the carriage 2 or tank body to move upward as a whole, realizing the backward flipping of the carriage 2 or tank body.

[0031] In addition, it should be noted that when the carriage 2 or tank body is flipped backward, the rear part of the carriage 2 or tank body is rotatably connected to the rear part of the frame through the rotatable connection method of a conventional rear-flip dump truck; the front and middle parts of the carriage 2 or tank body are not fixedly connected to the frame. When the push plate in the carriage 2 or tank body is pushed backward, the front and middle parts of the carriage 2 or tank body can be fixedly connected to the frame through locking pins, container locks, chains, etc.

[0032] Specifically, in this embodiment, a specific style of a push plate in a hydraulic cylinder dump truck is also provided: the push plate includes a frame and a plate body, the plate body is fixed on the frame; the push plate is installed in the carriage 2 or the tank body; the upper part of the plate body or the frame is provided with a hinge seat 4, of course, the hinge seat 4 is connected to the plate body and the frame at the same time, and should also belong to the protection scope of the utility model, and the upper end of the hydraulic cylinder 3 is rotatably connected to the hinge seat 4. It should be noted that the above-mentioned frame can be a frame with the front side of the plate body attached to the plate body, or it can be a frame structure extending forward on the plate body.

[0033] More specifically, in this embodiment, in order to prevent the push plate from deflecting sideways, longitudinal top beams are provided on both sides of the carriage 2, and guide rods are provided on the upper parts of the longitudinal top beams; a guide structure is also connected to the frame, and a guide hole is provided on the guide structure, and the guide rod is inserted into the guide hole. In order to facilitate locking the push plate, the locking device is provided on the guide rod, and the locking device can be any form such as a locking pin provided on the guide rod, a detachable blocking block, etc.

[0034] More specifically, this embodiment further provides a specific form of a locking device: the locking device includes a locking pin arranged on the longitudinal top beam, and the locking pin is detachably mounted on the guide rod.

[0035] More specifically, in this embodiment, support longitudinal rods 5 extending forward are provided on both sides of the upper part of the frame, support cross rods 6 are provided in front of the two support longitudinal rods 5, and the front parts of the support longitudinal rods 5 are connected by the support cross rods 6; the guide structure is provided on the support longitudinal rods 5.

[0036] Specifically, the carriage 2 or the tank body is provided with a fixing seat, which is connected to the push plate in a detachable manner. The fixing seat is a fixed structure, which is connected to the locking push plate in a detachable or openable manner.

[0037] More specifically, the locking device includes a locking rope or a locking chain connected to the fixed seat, and the locking rope or the locking chain is connected to the push plate in a detachable manner. The connection between the locking rope or the locking chain and the push plate can be a clasp connection, a hook connection, or any other detachable connection method.

[0038] Of course, the above description is only a preferred embodiment of the utility model, and does not limit the patent scope of the utility model. All equivalent structural changes made by using the contents of the utility model specification and drawings under the utility model concept of the utility model, or direct / indirect application in other related technical fields are included in the patent protection scope of the utility model and should be protected by the utility model.
