Specifically, the straight line where the connection part of the limiting plate and the carrier 41 is located is parallel to the roll shaft 42, the limiting plate is arranged at two side edges of the carrier 41, the angle between the limiting plate and the carrier 41 can be adjusted through rotation, when the plane plate in the limiting plate is locked by the self-locking structure, the angle between the limiting plate and the carrier 41 is kept unchanged, when the self-locking structure is unlocked, the limiting plate can rotate on the carrier 41, a carrier space is formed between the two limiting plates and the carrier 41, and when an oil tank part is carried, the oil tank part is placed in the carrier space. When the oil tank part is carried, firstly, the carrying trolley 100 is moved to a position close to the oil tank part placing rack, after the carrying platform 4 is lifted to a proper height, the limiting plates close to one side of the oil tank part placing rack are put down to be lapped on the oil tank part placing rack, the oil tank part can be pushed onto the roll shaft 42 through the limiting plates on one side, the limiting plates on the other side are rotated to a proper position in advance according to the size of the oil tank part and are locked by using the self-locking structure, after the oil tank part is pushed onto the carrying platform 4, the limiting plates close to one side of the oil tank part placing rack are rotated to a proper position and are locked by using the self-locking structure, at the moment, the oil tank part is placed in the carrying space, and the two sides of the roll shaft 42 in the sliding direction are fixed by the limiting plates, so that the oil tank part is not easy to fall in the conveyed way. After the transport trolley 100 with the oil tank part is moved to the vicinity of the oil tank part transport trolley, firstly, the carrying platform 4 is lifted to a position height suitable for the oil tank part transport trolley to place the oil tank part, then a limiting plate close to one side of the oil tank part transport trolley is unlocked and opened, the limiting plate is lapped on the oil tank part transport trolley, and the oil tank part is pushed onto the oil tank part transport trolley through the limiting plate. Through setting up the limiting plate, can play the effect of fixed oil tank portion article on the one hand, on the other hand can regard as the passageway of oil tank portion article when transport trolley 100 loads or uninstalls oil tank portion article, reduce when propelling movement oil tank portion article because transport trolley 100 and oil tank portion article rack or oil tank portion article transport vechicle between the too big and lead to the oil tank portion article to drop the risk of damage.

In an embodiment of the present utility model, the carrying trolley 100 further includes a traveling wheel, the traveling wheel 5 is mounted at the bottom of the traveling bracket 1, and the traveling wheel 5 is used for supporting the carrying trolley 100 to travel on the ground. Referring to fig. 1, four travelling wheels 5 are respectively disposed at four corners of the bottom bracket 11, and the travelling wheels 5 may be universal wheels. Through set up walking wheel 5 in the bottom of walking support 1, can make transport trolley 100 remove more conveniently, reduce user's the use degree of difficulty, improve simultaneously and transport the stability of oil tank portion article.

In one embodiment of the present utility model, the bottom bracket 11 includes a horizontal rod 111 and a vertical rod 112, the horizontal rod 111 is used to fix the rod 112, and the bottom end of the rod 112 is disposed close to the ground. Referring to fig. 1 specifically, on the basis that the travelling wheel 5 is mounted on the travelling support 1, the bottom end of the upright rod 112 vertically arranged on the bottom support 11 is close to the ground, but the bottom end of the upright rod 112 is not attached to the ground. Wherein, the horizontal pole 111 mainly used fixes pole setting 112, increases the steadiness of bottom support 11, and the vertical distance of pole setting 112 bottom and walking wheel 5 bottom keeps being less than within 10cm, so, when the transfer trolley 100 is about to topple over because of the effect such as eccentric force in the removal process, pole setting 112 can in time play the effect of support, avoids transfer trolley 100 wholly to take place the condition emergence of toppling over.

Referring to fig. 1, in an embodiment of the present utility model, the cart 100 further includes a pushing handle 6, the pushing handle 6 includes a pushing handle frame 61 and an armrest 62, the pushing handle frame 61 is mounted on one side of the walking frame 1, the armrest 62 is mounted on the top of the pushing handle frame 61, and the control member is mounted on the armrest 62. The number of push handles 6 is two, the two push handles 6 are arranged on the same side of the walking bracket 1, a certain distance is reserved between the two push handles 6, the push handles 6 are provided with handrails 62, the handrails 62 are connected to the walking bracket 1 through a push handle frame 61, an operator can control the movement of the carrying trolley 100 through pushing and pulling the handrails 62, meanwhile, the control pieces are integrated on the handrails 62 on the two sides, in one embodiment, the control piece integrated on the left-hand handrail 62 can control the carrying platform 3 to descend, the control piece integrated on the right-hand handrail 62 can control the carrying platform 3 to ascend, and through the arrangement, the operator can flexibly control the lifting of the carrying platform 3 under the condition of not changing the using posture, and the working efficiency of carrying work is improved.
