Example one

This embodiment is substantially as shown in figures 1 and 2 of the accompanying drawings: a device for handling kerbstones comprises a main body, a wheel axle 2, a connecting rod 5 and two wheels 1. The main part includes mainboard 3 and three

bracing piece

4, and 3 levels of mainboard set up,

shaft

2 and 3 welding of mainboard, and 4 lower extremes of every bracing piece are connected with mainboard 3 respectively, and 4 upper ends of three bracing piece are connected with connecting rod 5 respectively. The three support rods 4 constitute a triangular pyramid, which can ensure the stability that the strength of the entire body has been connected.

Two wheels 1 are connected with 2 both ends of shaft respectively, and 5 one end welding of connecting rod has link 6, and the other end joint has the handle, and link 6 both ends are equipped with fixed unit respectively. Specifically, still include two and connect rope 7, two are connected rope 7 and are located link 6 both ends respectively, and every connects 7 both ends of rope and be connected with link 6 tip and fixed unit respectively. Fixed unit includes two-way lead screw 14 and two fixed

pipes

11, and 11 one end of every fixed pipe is equipped with the internal thread respectively, and 11 other ends of every fixed pipe are equipped with

cardboard

8, and 8 the inner of cardboard is equipped with a plurality of dogtooths 13, and the setting of dogtooth 13 can increase the frictional force of cardboard 8 to the curb stone, prevents the curb stone landing in handling. Two ends of the bidirectional screw rod 14 are respectively in threaded fit with the fixed pipe 11 and are not self-locked. The bidirectional screw rod 14 is further welded with a nut 15, and the nut is convenient to rotate. The fixing unit further comprises a guide rod 12, and the guide rod 12 is parallel to the fixing tube 11 and is connected with the clamping plate 8 in a sliding mode. The end part of the connecting rod 5 is provided with a handle. The fixed unit further comprises a connecting transverse plate 9, a guide rod 12 and two connecting vertical plates 10, the two connecting vertical plates 10 are respectively connected with two ends of the connecting transverse plate 9, the guide rod 12 is parallel to the fixed pipe 11 and is respectively connected with the connecting vertical plates 10 in a sliding mode with the guide rod 12 and the fixed pipe 11, and the end portions of the guide rod 12 are connected with the clamping plate 8 in a clamping mode.

The specific implementation process is as follows: in this scheme, when needs transport curb, the workman holds the tip of connecting rod 5 and is the handle, then uses shaft 2 as the axle and rotates whole device, makes fixed unit tip move down and be close to the curb, makes the curb be located between two fixed units, then uses two fixed units to fix the curb respectively. When fixing the curb, place every fixed unit's cardboard 8 respectively in the both sides of curb, then rotate two-way lead screw 14, because two-way lead screw 14 both ends respectively with fixed 11 screw-thread fits of pipe, so can drive two cardboard 8 simultaneously and remove and press from both sides the curb tightly to the curb when two-way lead screw 14 rotates. Then, the worker rotates the hand-push wheels 1 to convey the curb to a corresponding position and then reversely rotates the bidirectional screw rod 14 to put down the curb.

Because two-way lead screw 14 and two fixed pipe 11 screw-thread fit, so only need to rotate two-way lead screw 14 both can reach two cardboard 8 and remove and fix the curb to the curb simultaneously, convenient operation can make two cardboard 8 atress to the curb both sides even like this moreover, and the curb through screw-thread fit's mode also can both press from both sides tightly to the curb of different thickness. And because the bidirectional screw rod 14 is in threaded fit with the two fixed pipes 11 and is self-locked, the two clamping plates 8 can be ensured to be always in a clamping state on the curb, and the curb is prevented from falling off in the moving process.

Example two

Referring to fig. 3 and 4, the difference between the first embodiment and the second embodiment is that the connecting rod 5 is a telescopic rod, specifically, the connecting rod 5 includes an outer connecting rod 30 and an inner connecting rod 16, the outer connecting rod 30 is provided with an accommodating cavity 18, and two sides of the outer connecting rod 30 are respectively provided with a fixing hole 20 communicated with the accommodating cavity 18. The connecting inner rod 16 is positioned within the receiving cavity 18 and is slidable along the receiving cavity 18. In the embodiment, the curb conveying device further includes a limiting part for limiting the sliding of the inner connecting rod 16 along the outer connecting rod 30, specifically, the inner connecting rod 16 is further provided with a limiting rod 19, a cavity 27 is arranged inside the inner connecting rod 16, a control rod 21 is slidably connected in the cavity 27, and an inclined surface 26 is arranged at the end of the control rod 21. The limiting rod 19 is horizontally connected with the cavity 27 in a sliding mode, the limiting rod 19 is provided with a groove 25 matched with the inclined surface 26, and the limiting rod 19 can penetrate through the fixing hole 20. A first pressure spring 28 is arranged between the two limiting rods 19, a limiting flange 23 is arranged in the first chamber 27, a circular ring 24 is arranged at the end part of the control rod 21 far away from the limiting rods 19, a second pressure spring 29 is arranged between the circular ring 24 and the limiting flange 23, and two ends of the second pressure spring 29 are respectively abutted against the limiting flange 23 and the circular ring 24.

When using, can change the length of telescopic link and change the distance of shaking hands from 2 intervals of shaft, can know according to lever principle that the length of telescopic link is longer, then laborsaving more during transport curb. In this scheme, can adjust the length of telescopic link as required to more laborsaving, more convenient transport curb.

In the original state, the stopper rod 19 passes through the fixing hole 20, so that the connection inner rod 16 and the connection outer rod 30 cannot move relatively. During adjustment, the control rod 21 is pressed, the control rod 21 slides in the cavity 27, at the moment, the second pressure spring 29 is compressed, along with the sliding of the control rod 21, the inclined surface 26 is in contact with the groove 25, the groove 25 slides inwards and slides into the cavity 27 under the action of the inclined surface 26, at the moment, the first pressure spring 28 is compressed, the limiting rod 19 is not matched with the limiting hole any more, the inner rod 16 can be slidably connected along the accommodating cavity 18, after the connecting inner rod 16 slides to a proper position, the control rod 21 is released, the first pressure spring 28 and the second pressure spring 29 both return to original shapes, and the control rod 21 returns to an initial position under the action of the second pressure spring 29. The two limiting rods 19 slide outwards under the action of the first pressure spring 28 and penetrate through the fixing holes 20 to limit the position of the connecting outer rod 30 and the connecting inner rod 16, so that the relative sliding between the connecting inner ring and the connecting outer rod 30 is avoided.

The foregoing is merely an example of the present invention and common general knowledge of known specific structures and features of the embodiments is not described herein in any greater detail. It should be noted that, for those skilled in the art, without departing from the structure of the present invention, several changes and modifications can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicability of the patent. The scope of the claims of the present application shall be determined by the contents of the claims, and the description of the embodiments and the like in the specification shall be used to explain the contents of the claims.
