When the slide bar 14 rises, drive the lifting hook and rise, the lifting hook drives rings 44 and rises, rings 44 stimulate two connecting rings 43 and rise, the one end that rings 44 were kept away from to two connecting rings 43 is close to each other, the one end that splint 41 was kept away from to two articulated rods 42 of pulling is close to each other, because two articulated rods 42 articulate each other and form the scissors form, the other end of two articulated rods 42 is close to each other, drive two splint 41 and be close to each other and press from both sides the way tartar that will shift between two splint 41 tightly, and then draw the way tartar to rise and leave ground, the setting up of rubber pad increases the frictional force between way tartar and the splint 41, make way tartar difficult because gravity drops when the transport.
Referring to fig. 2 and 3, a counterweight 5 is further disposed on the end of the frame 1 away from the clamping assembly 4. A supporting cross rod 15 is fixedly arranged above the wheel 2 between the two supporting rods 11, the supporting cross rod 15 is perpendicular to the supporting rods 11, and two ends of the supporting cross rod 15 are respectively fixed on the two supporting rods 11. Offer the perforation that supplies driving screw 31 to slide to wear to establish on supporting horizontal pole 15, be provided with dead lever 51 along 11 length direction of bracing piece between supporting screw and the connecting rod 12 of keeping away from centre gripping subassembly 4, dead lever 51 is square body shape and middle part on connecting rod 12 and supporting horizontal pole 15 of its both ends difference fixed connection, balancing weight 5 offers the slide opening with dead lever 51 adaptation, 5 slip cap of balancing weight locate on dead lever 51, and when balancing weight 5 slides to being located dead lever 51 and being close to the one end of supporting horizontal pole 15, balancing weight 5 is located wheel 2 directly over. The counterweight 5 slides on the fixed rod 51 along the length direction of the fixed rod 51, namely along the length direction of the support rod 11. When not using balancing weight 5, balancing weight 5 slides to being located dead lever 51 and being close to the one end that supports horizontal pole 15, and balancing weight 5 is located wheel 2 directly over this moment, and balancing weight 5 can not exert pressure to the both ends of dolly, the operating personnel of being convenient for remove the dolly. When the balancing weight 5 slides to the end of the fixing rod 51 far away from the supporting cross rod 15, the weight of the end, far away from the clamping component 4, of the frame 1 can be increased, the pressure on the clamping component 4 and the curbstone is increased, and the operation of an operator is more labor-saving.
Referring to fig. 3 and 4, a clamping assembly 6 is further arranged between the counterweight 5 and the supporting cross rod 15 and the connecting rod 12, the clamping assembly 6 comprises a clamping portion arranged on the counterweight 5 and a fixing block 63 fixedly arranged on the supporting cross rod 15 and the connecting rod 12, and two sides of the clamping portion in the sliding direction of the counterweight 5 are provided. Joint portion is including being fixed in the elasticity joint board 61 on the balancing weight 5, and joint board 61 perpendicular to balancing weight 5, joint board 61 keep away from the one end bottom surface downwardly extending of balancing weight 5 and form joint piece 62, and joint piece 62 is right angled triangle's cylinder for the terminal surface, and the inclined plane of joint piece 62 deviates from balancing weight 5 and sets up. When balancing weight 5 slides to and supports the diaphragm butt, the distance that one side that joint piece 62 is close to balancing weight 5 is greater than the fixed block 63 and keeps away from 5 one side of balancing weight to balancing weight 5's distance, and the highly perpendicular distance that joint piece 62 kept away from joint plate 61 one end and support horizontal pole 15 of fixed block 63 just is less than the lower surface of joint plate 61 to the distance of supporting horizontal pole 15. When balancing weight 5 moved to the tip of dead lever 51, joint piece 62 inclined plane earlier with fixed block 63 butt, joint board 61 kickup, balancing weight 5 slide to with support horizontal pole 15 or connecting rod 12 butt when, joint piece 62 moves to the one side that is located fixed block 63 and keeps away from balancing weight 5, and joint piece 62's right angle limit and fixed block 63 butt realize that the joint is fixed. When the balancing weight 5 needs to be moved, the clamping plate 61 is manually bent upwards, and the balancing weight 5 can be moved by separating the clamping block 62 from the fixing block 63.
The implementation principle of the embodiment is as follows: when carrying the way tartar, make two splint 41 be located the both sides of way tartar, operating personnel exerts downward pressure through handle 13 to the one end that centre gripping subassembly 4 was kept away from to frame 1, makes slide bar 14 rise, drives two splint 41 through the drive division and is close to each other, presss from both sides the way tartar tightly, continues to push down frame 1 to centre gripping subassembly 4 and mentions the way tartar and can carry the way tartar. When carrying the road traffic stone of different weight, slide 14 through sliding on bracing piece 11, change the proportion of the power arm and the resistance arm of frame 1 in order to reach laborsaving effect. When the balancing weight 5 slides in the direction away from the supporting cross rod 15, the weight of one end of the frame 1 away from the clamping component 4 is increased, and the operation of an operator is more labor-saving.
The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
