Carrying trolley for large-size oil cylinder

[0016] In order to easily understand the technical means, creative features, purpose and effect of the present invention, the present invention will be further explained in conjunction with specific drawings below.

[0017] Such as figure 1 , figure 2 As shown, a large oil tank carrying trolley includes a base frame 1, a lifting frame 2, a V-shaped push rod 3, a connecting rod 4, a handle 5, and a front fork 6. The lifting frame 2 has the same shape as the base frame 1, which is lifted The frame 2 is located above the base frame 1. The V-shaped push rod 3 is divided into a short side and a long side. The short side has the same length as the connecting rod 4. The short side of the connecting rod 4 and the V-shaped push rod 3 will lift the frame 2 and the base 1 The upper corresponding positions are connected and form a parallelogram structure from the side. The handle 5 is fixed on the long side of the V-shaped rod 3, and the front fork 6 is fixed on the front end of the lifting frame 2. A number of pairs of grooves 7 are provided on the front fork 6 and rubber pads 8 are provided in the grooves 7. A counterweight box 9 is provided at the rear of the underframe 1. The chassis 1 is provided with four universal wheels 10.

[0018] When moving goods, push the front fork 6 on the trolley into the bottom of the cylinder, so that the piston rod of the cylinder is above the groove 7, press the V-shaped push rod 3 downward, tilt the cylinder through the principle of leverage, and drag the cylinder backwards. Push the cart to remove the oil cylinder from the shelf, loosen the V-shaped push rod 3, and the oil cylinder falls on the bottom frame 1 with the lifting frame 2 and drag the small cart to complete the transportation. The function of the counterweight box 9 is that the oil cylinder does not fall on the center of gravity of the trolley, and the counterweight box 9 needs to be used to balance the trolley to make the transportation more stable.

[0019] The basic principles and main features and advantages of the present invention have been shown and described above. Those skilled in the industry should understand that the present invention is not limited by the above-mentioned embodiments. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements fall under the protection of the claims. Within the scope of the present invention. The scope of protection claimed by the present invention is defined by the appended claims and their equivalents.
