DETAILED DESCRIPTION

[0020] A curb transfer device capable of single-person operation, comprising a curb 1, as shown in the accompanying Figure 1 ; also comprising a hollow hand grip 2, the inside of the hand grip 2 is provided with a telescopic mechanism, the telescopic mechanism can extend to both sides of the axial direction of the hand grip 2, both ends of the telescopic mechanism are provided with a lock sleeve mechanism, and the two ends of the curb 1 are respectively arranged in the inside of the lock sleeve mechanism.

[0021] The telescopic mechanism inside the hand grip 2 extends to both sides of the hand grip 2, so that the lock sleeve mechanism at both ends can be placed at both ends of the curb 1, and then the telescopic mechanism inside the hand grip 2 is retracted towards the hand grip 2, so that the two ends of the lock sleeve mechanism can be sleeved on both ends of the curb 1, then the operating personnel can lift the hand grip 2, the curb 1 is lifted and transferred to the installation position by the upward lifting force, through the cooperation of the telescopic mechanism and the lock sleeve mechanism, only one person can complete the transfer of the curb 1, and compared with the existing curb clamp which relies on the friction force between the two sides of the curb and the clamp to transfer, the curb 1 only needs to overcome its own gravity, which is relatively labor-saving, and further improves the transfer efficiency of the curb 1.

[0022] As shown in the accompanying Figure 2 , and Figure 3 ; the telescopic mechanism comprises an installation vertical plate 3 located inside the hand grip 2, the installation vertical plate 3 divides the inside of the hand grip 2 into a left cavity and a right cavity which are both rectangular in cross section, the left cavity and the right cavity are both provided with a telescopic assembly, a double shaft motor 4 is installed on the installation vertical plate 3, threaded rods 5 are fixedly installed on both ends of the output shaft of the double shaft motor 4, and the two threaded rods 5 are movably connected with the two telescopic assemblies respectively, and are used to drive the telescopic assemblies to extend and retract.

[0023] The telescopic assembly comprises an inner rack 6 fixedly installed on the inner top wall and the inner bottom wall of the hand grip 2, a rectangular shell one 7 is slidably arranged in the inside of the hand grip 2, gear wheels 8 are rotatably arranged on the inner top wall and the inner bottom wall of the rectangular shell one 7, and the two gear wheels 8 are engaged with the corresponding inner racks 6 respectively.

[0024] A rectangular shell two 9 is slidably arranged in the inside of the rectangular shell one 7, outer racks 10 are fixedly installed on the outer top wall and the outer bottom wall of the rectangular shell two 9, and the two outer racks 10 are engaged with the corresponding gear wheels 8 respectively.

[0025] The side end of the rectangular shell one 7 is fixedly provided with a nut 11, and the nut 11 is threadedly connected with the corresponding threaded rod 5.

[0026] The double-shaft motor 4 can drive the rectangular shell one 7 and the rectangular shell two 9 to stretch and retract, so as to realize the movement of the lock sleeve mechanism. After the double-shaft motor 4 is started, the threaded rod 5 is driven to rotate, and the nut 11 and the rectangular shell one 7 are horizontally moved through the thread cooperation between the threaded rod 5 and the nut 11. Since the gear 8 on the rectangular shell one 7 is in meshing connection with the internal gear rack 6, when the rectangular shell one 7 is horizontally moved, the gear 8 is rotated under the meshing action of the internal gear rack 6. Since the internal gear rack 6 is in meshing connection with the external gear rack 10 on the rectangular shell two 9, when the gear 8 is rotated, the rectangular shell two 9 is horizontally moved. Thus, the horizontal movement of the rectangular shell one 7 and the rectangular shell two 9, i.e. the stretching and retracting of the stretching and retracting assembly, can be completed through the cooperation of the internal gear rack 6, the gear 8 and the external gear rack 10.

[0029] Generally, the size of the curbstone 1 is relatively smaller than that of the placement hole 14, so that the curbstone 1 is conveniently placed. Thus, there is a gap between the curbstone 1 and the placement hole 14, and the curbstone 1 may slightly slide during the transportation. Therefore, the mounting hole is provided on the inner side wall of the placement hole 14 for mounting the spring, the vertical column and the sleeve, so as to form a simple anti-skid assembly. When the curbstone 1 is placed in the placement hole 14, the surface of the curbstone 1 is in contact with the arc-shaped end face of the sleeve, the sleeve and the spring are pressed into the mounting hole, the elastic force of the spring also reversely presses the arc-shaped end face of the sleeve to the curbstone 1, and the friction force of the three side faces of the curbstone 1 is increased to prevent the curbstone 1 from sliding.

[0030] The upper surface of the hand grip 2 is provided with a control button, and the control button is electrically connected with the double-shaft motor 4. The control button comprises a motor start-stop button, a motor forward rotation button and a motor reverse rotation button.
