Detailed Description

In order to make the technical solution of the present invention more comprehensible, embodiments are described in detail below with reference to the accompanying drawings.

The utility model provides a weight transfer car (buggy), as shown in fig. 1-3, mainly include frame 1, spandrel girder 2, locator 6, locating pin 3, jib loading boom 5, auxiliary arm 8 and weight gallows 10.

The frame 1 is a metal welded rectangular frame structure, the span is greater than the length of a ground scale pan, the frame 1 comprises a table top and four support legs connected with and supporting the table top, the lower ends of the two support legs in front are provided with directional wheels, and the lower ends of the two support legs in rear are provided with universal wheels. Two bearing beams 2 are welded on a rectangular frame structure of the frame 1, and a positioner 6, a crane boom connecting shaft 11, an auxiliary boom connecting shaft 7 and an anti-falling stop lever 12 are all arranged on the bearing beams 2 and used for bearing the weight of a weight 13 and installing other main components.

The riser of locator 6 is two, is fixed in on 1 mesa of frame to arrange along the fore-and-aft direction, a plurality of constant head tank has been seted up to 5 angles of jib loading boom when aiming at not co-altitude weight on the riser, and the constant head tank is along the arc distribution around a centre of a circle. The arc is a quarter circle located at the rear upper part of the circle center, and the crane boom 5 rotates along one side. Certainly, in another embodiment, the arc shape can also be a semicircle, the crane boom 5 can rotate along two sides, and can play a role in lifting the weight, the difference is that the weight can be lifted only towards one direction when the quarter circle is formed, and the weight can be lifted towards the front and back directions when the semicircle is formed.

The cargo boom 5 is hinged on a horizontal cargo boom connecting shaft 11 on the table top, is arranged between two vertical plates of the positioner 6 and can rotate back and forth in a vertical plane, and the cargo boom connecting shaft 11 abuts against the circle center surrounded by the positioning groove of the vertical plate of the positioner 6. The jib connection shaft 11 divides the jib 5 into a power arm section 51 above the table top and a resistance arm section 52 below the table top. The positioning pin 3 is attached to the power arm section 51 of the crane boom 5 and can be clamped into each positioning groove of the positioner 6, so that the crane boom 5 can be kept fixed when rotating to the angle corresponding to the positioning groove. The top of the arm section is provided with a return spring 4 which provides elastic force for the positioning pin 3 to be clamped into the positioning groove.

The upper end of the auxiliary arm 8 is hinged on an auxiliary arm connecting shaft 7 on a table top parallel to the jib connecting shaft 11, the auxiliary arm 8 is positioned right behind the jib 5, and the length of the auxiliary arm 8 is equal to that of the resistance arm section 52 of the jib 5. In another embodiment, the auxiliary arm 8 can be located right in front of the crane arm 5, and can be used for lifting the weight of the auxiliary crane arm 5, the difference is that the crane arm 5 applies a pulling force or a pushing force to the auxiliary arm 8, but the effect is consistent. The two ends of the weight hanger 10 are hinged to the lower end of the resistance arm section 52 of the crane arm 5 and the lower end of the auxiliary arm 8 through a hanger connecting shaft 9, can rotate freely, ascend and descend, and achieve the function of lifting the weight 13. The weight hanger 10 is provided with a plurality of jaws of different sizes for lifting weights 13 of different diameters or weights, and a plurality of weights 13 can be taken out simultaneously or in several times, and the jaws are shaped like a U in plan view as shown in fig. 4 to 5, and have one open end for catching the neck of the weights 13.

An anti-falling blocking rod 12 is hung under the table board in front of the positioner 6, the anti-falling blocking rod 12 is adjusted in height through screws, and comprises a cross rod, when the weight hanger 10 is hung, the front end of a fork opening of the anti-falling blocking rod is lapped on the cross rod of the anti-falling blocking rod 12, and meanwhile, the cross rod seals the fork opening. As can be seen, the stopper bar 12 is located forward in the moving direction of the weight 13 lifted by the weight hanger 10, i.e., forward of the fork.

The process of transferring the weights by the weight transfer trolley is as follows: when the weights 13 are transferred, the positioning pin 3 on the crane boom 5 is pulled up, the crane boom 5 is rotated to enable the weight hanger 10 to reach the height of the neck of the weights 13, the weight transfer trolley is pushed forward to enable the fork mouth of the weight hanger 10 to be completely clamped into the neck of the weights 13, the crane boom 5 is pressed down to be rotated into the positioning groove of the corresponding scale of the positioner 6, the positioning pin 3 is put down, and the positioning pin 3 is automatically clamped into the positioning groove by the return spring 4. When the weight 13 is transferred or stored, the crane boom 5 is pressed down to the lowest point to reach the lowest positioning groove of the positioner 6, the positioning pin 3 is put down, and simultaneously, the front end of the fork opening of the weight hanger 10 is lapped on the cross rod of the anti-falling stop rod 12 and the fork opening is sealed by the cross rod, so that the weight 13 can be prevented from falling off from the front end of the fork opening when being transferred.

The above embodiments are only used for illustrating the technical solutions of the present invention and not for limiting the same, and those skilled in the art can modify or equally replace the technical solutions of the present invention, and the protection scope of the present invention is subject to the claims.
