Description

Technical Field

[0001] The utility model relates to the technical field of electric flat cars, in particular to a heavy-duty trackless lifting electric flat car with good transportation stability. Background Technique

[0002] An electric flat car is a very common transportation tool in factory areas and docks. It has the advantages of large load capacity, being not afraid of dirt and being smashed. Through the electric flat car, goods with larger weights can be transported and transferred, thus facilitating production.

[0003] In the prior art, it is impossible to dump the goods while lifting the goods. The anti-collision device occupies space and will be affected when the flat car turns. For this reason, we propose a heavy-duty trackless lifting electric flat car with good transportation stability. Content of the Utility Model

[0004] The technical problem to be solved by the utility model is to overcome the existing defects and provide a heavy-duty trackless lifting electric flat car with good transportation stability, which can dump the goods while lifting the goods. The anti-collision device reduces the occupied space and ensures normal use at the same time, and can effectively solve the problems in the background technique.

[0005] To achieve the above purpose, the utility model provides the following technical scheme: A heavy-duty trackless lifting electric flat car with good transportation stability, including a flat car main body, a lifting unit, a fixing unit and an anti-collision unit;

[0006] Flat car main body: Installed with a lifting unit, a fixing unit and an anti-collision unit;

[0007] Lifting unit: Comprising a first rectangular groove, a second rectangular groove, a hydraulic press, a mounting ring, a mounting frame and a placing plate. A first rectangular groove is opened at the upper end of the flat car main body. A second rectangular groove is opened inside the first rectangular groove. Four hydraulic presses are fixedly connected to the four corners inside the second rectangular groove. The upper end of each hydraulic press is fixedly connected with a mounting ring. There are four mounting frames, two of which are fixedly connected to the front side of the lower end of the placing plate. Two front-rear direction sliding grooves are opened at the rear side of the lower end of the placing plate. The other two mounting frames are slidably connected with the rear side sliding grooves of the placing plate. The mounting frame and the mounting ring are rotationally connected.

[0008] The first rectangular groove and the second rectangular groove are used to fix and hide the placing plate and the second rectangular groove respectively. The hydraulic press drives the placing plate to lift. Through the connection between the mounting ring and the mounting frame, when the hydraulic presses on the same side rise, the placing plate tilts, so as to achieve the purpose of facilitating the pouring of goods.

[0009] Further, the anti-collision unit includes a rectangular installation groove, a damping rod, a spring, a mounting plate, a rubber shock pad, a rectangular through-hole, and a radar rangefinder. Two rectangular installation grooves are formed at the front and rear ends of the flat car body. Two damping rods are fixedly connected inside the rectangular installation groove. The other end of the damping rod is fixedly connected with a mounting plate. A spring is sleeved outside the damping rod. A circular chute is formed in the middle of the lower end of the rectangular installation groove. A rectangular through-hole is formed at the front end of the rubber shock pad. The front end of the mounting plate is fixedly connected with a rubber shock pad. A radar rangefinder is fixedly connected in the middle of the front end of the mounting plate. The device is shock-absorbed by the damping rod and the spring. The rubber shock pad is fixed by the mounting plate. The rubber shock pad protects the mounting plate during collision, reducing the loss of collision repair. The radar rangefinder is used for monitoring and early warning. The rectangular installation groove hides the mounting plate during normal use and enables the mounting plate to pop out for collision protection when a collision is about to occur.

[0010] Further, the anti-collision unit further includes a circular through-hole, an electric telescopic rod, and a mounting and fixing frame. A circular through-hole is formed in the middle of the lower end of the rectangular installation groove. The front and rear sides of the lower end of the flat car body are fixedly connected with a mounting and fixing frame. The upper end of the mounting and fixing frame is fixedly connected with an electric telescopic rod. The electric telescopic rod passes through the circular through-hole and is slidably connected with the circular chute at the lower end of the mounting plate. The electric telescopic rod is fixed by the mounting and fixing frame, and the mounting plate is fixed by the electric telescopic rod, reducing the size of the flat car during use and the obstruction during movement.

[0011] Further, the fixing unit includes a hidden groove and a fixing column. Two hidden grooves are formed on the right side of the upper end of the flat car body. The fixing column is fixedly connected inside the hidden groove. The fixing ropes are fixed by the hidden groove and the fixing column, thereby fixing the items on the flat car.

[0012] Further, the fixing unit further includes an installation groove, a motor, a fixing hook, an elastic cord, and a rope winding wheel. Two installation grooves are formed on the left side of the upper end of the flat car body. The motor is fixedly connected inside the installation groove. The output shaft of the motor is fixedly connected with a rope winding wheel. The other end of the rope winding wheel is rotatably connected with the installation groove. The elastic cord is wound around the outside of the rope winding wheel. The other end of the elastic cord is fixedly connected with a fixing hook. The rotation of the motor drives the rope winding wheel to rotate, and the items on the placement plate are fixed by the elastic cord and the fixing hook, thereby achieving the purpose of fixing the items on the flat car.

[0013] Further, it also includes a steering wheel, driving wheels, a second motor, and a motor fixing bracket. Two steering wheels are fixedly connected to the front side of the lower end of the flat car body. Two driving wheels are fixedly connected to the rear side of the lower end of the flat car body. Two motor fixing brackets are fixedly connected to the rear side of the lower end of the flat car body.
