Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

As shown in fig. 1-4, a tire crane with a locking function includes a main beam 1, a traveling trolley 2 is disposed on the main beam 1, end beams 3 are disposed at two ends of the main beam 1, support legs 4 are disposed at bottoms of the end beams 3, a traveling beam 5 is disposed at bottom of each support leg 4, a plurality of groups of tire-type traveling mechanisms 6 are uniformly disposed at bottom of the traveling beam 5, a plurality of installation spaces 8 are disposed inside the traveling beam 5, locking structures 7 are installed in the installation spaces 8, and each group of tire-type traveling mechanisms 6 corresponds to one locking structure 7.

Stop structure 7 includes the actuating lever 9 that the level set up, the electric putter 10 of the vertical setting of fixedly connected with between the both ends of actuating lever 9 and installation space 8's the bottom, electric putter 10 can drive actuating lever 9 and reciprocate, the bottom at actuating lever 9 both ends articulates there is stop lever 11, installation space 8's bottom is provided with the through-hole, stop lever 11 passes the through-hole setting downwards, stop lever 11's bottom fixedly connected with backstop 12, backstop 12 is triangular prism column structure, when actuating lever 9 descends to the lowest position, the bottom and the ground laminating of backstop 12, an inclined plane of backstop 12 sets up towards tire 13, the backstop 12 at both ends corresponds the front wheel and the rear wheel of tire formula running gear 6 respectively.

The middle of the driving rod 9 is evenly hinged with a plurality of groups of stop plates 14, each group of stop plates 14 comprises two oppositely arranged stop plates 14, the bottom of the installation space 8 is provided with a through hole, each stop plate 14 downwards penetrates through the through hole, each group of stop plates 14 is arranged between two adjacent tires 13 in the tire type travelling mechanism 6, the bottom of each stop plate 14 is fixedly connected with a backstop 12, and the two backstops 12 respectively correspond to the tires 13 on two sides. An extension spring 15 is arranged between the two stop plates 14 in each group of stop plates 14, guide blocks 16 which are arranged in a downward inclined mode are fixedly connected to the stop plates 14, the inclined surfaces of the guide blocks 16 are attached to the side walls of the through holes in the bottoms of the walking beams 5, when the drive rods 9 drive the stop plates 14 to move downwards, the side walls of the through holes can extrude the guide blocks 16 outwards, the backstop 12 is made to be close to the tire 13, the moving distance of the tire 13 is smaller, and the stopping effect is better.
