[0018] The utility model is described in detail below in conjunction with the accompanying drawings and specific implementation methods.
[0019] like Figure 1-2 A curbstone transport hoisting vehicle includes a vehicle bar 10, which is arranged along the Y-axis direction. The vehicle bar 10 fixes the upper end of a vertical rod 20, and the vertical rod 20 is arranged along the Z-axis direction. The lower end of the vertical rod 20 fixes an axle 30, and the axle 30 is arranged along the X-axis direction. A wheel 31 is hinged at both ends of the axle 30.
[0020] like Figure 1 The head of the vehicle rod 10 is provided with a rope fixing portion 12, the rope fixing portion 12 fixes one free end of the rope 40, and the other free end of the rope 40 is connected to the connecting ring 41, and the connecting ring 41 is connected to the sling.
[0021] like Figure 2 The connection between the connecting ring 41 and the sling is specifically as follows: the sling includes a left clamp 50 and a right clamp 60 that are symmetrically arranged, and the left clamp 50 and the right clamp 60 are hinged together through a pin 70;
[0022] The lower end of the left clamp 50 is hinged to the left clamping block 55, and the upper end thereof is hinged to one end of the left rod 51, and the other end of the left rod 51 is fixed to the left ring body 52, and the left ring body 52 is connected to the connecting ring 41;
[0023] The lower end of the right clamp 60 is hinged to the right clamping block 65 , and the upper end of the right clamp 60 is hinged to one end of the right rod 61 . The other end of the right rod 61 is fixed to the right ring body 62 , and the right ring body 62 is connected to the connecting ring 41 .
[0024] like Figure 4 The outer side surfaces of the left clamping block 55 and the right clamping block 65 are both friction surfaces 551.
[0025] like Figure 6 When clamping the curb, if the positions of the left clamping block 55 and the right clamping block 65 are incorrect (for example, the upper edge 553 of the friction surface 551 of the left clamping block 55 first contacts the curb 90), the left clamping block 55 may rotate clockwise and the upper surface 554 of the left clamping block 55 may contact the curb 90, causing the curb to fail to be clamped.
[0026] For this purpose, see Figure 2 The lower section of the left clamp 50 is fixed with a left spring seat 53, and a left tension spring 54 is provided between the left spring seat 53 and the left clamping block 55, so that the lower section of the left clamp 50 and the left clamping block 55 remain parallel when the left clamping block 55 does not contact the curb 90;
[0027] The lower section of the right clamp 60 fixes the right spring seat 63 , and a right tension spring 64 is provided between the right spring seat 63 and the right clamping block 65 , so that the lower section of the right clamp 60 remains parallel to the right clamping block 65 when the right clamping block 65 does not contact the curb 90 .
[0028] See also Figure 4 When clamping the curb, the friction surface 551 of the left clamping block 55 and the lower edge 552 of the friction surface 551 of the right clamping block 65 first contact the curb 90, and then the left clamping block 55 rotates clockwise, see Figure 5 , the friction surface 551 of the left clamping block 55 and the friction surface 551 of the right clamping block 65 both contact the curb 90, completing the curb clamping.
[0029] like Figure 1 The car bar 10 and the vertical rod 20 are fixed by two oblique supports 13, and the car bar 10, the vertical rod 20 and the oblique supports 13 form a triangle. The triangle is relatively stable and convenient for fixing the car bar 10 and the vertical rod 20.
[0030] Its working principle is:
[0031] When using, Figure 3-6 , including the following steps:
[0032] S1. Hold the rear end of the handlebar 10 with your hand ( Figure 1 The right end of the curb), push the curb transport crane to 90 degrees of the curb.
[0033] S2, manually move the upper ends of the left clamp 50 and the right clamp 60 outward, keep the left clamp block 55 and the right clamp block 65 open, lift the tail end of the car bar 10, and make the head end of the car bar 10 ( Figure 1 The left end of the holding block 55 is lowered so that the left holding block 55 and the right holding block 65 are located outside the curb 90, see Figure 3 .
[0034] S3, loosen the upper ends of the left clamp 50 and the right clamp 60, and rely on the connection ring 41 to pull the upper ends of the left clamp 50 and the right clamp 60 through the left rod 51 and the right rod 61, so that the upper ends of the left clamp 50 and the right clamp 60 are close to each other, and the lower ends of the left clamp 50 and the right clamp 60 are close to each other, and the left clamping block 55 rotates clockwise and the right clamping block 65 rotates counterclockwise until the lower edges 552 of the two friction surfaces 551 contact the curb 90, see Figure 4 .
[0035] S4, by means of the connecting ring 41, the left rod 51 and the right rod 61 continue to pull the upper ends of the left clamp 50 and the right clamp 60, so that the upper ends of the left clamp 50 and the right clamp 60 are closer, and the lower ends of the left clamp 50 and the right clamp 60 are closer, until the friction surface 551 hugs the curb 90 tightly, and the curb is clamped. Figure 5 .
[0036] S5, the tail end of the vehicle bar 10 is pressed down to make the head end of the vehicle bar 10 rise, and the curb 90 is hoisted by the rope 40, the connecting ring 41, and the hoist.
[0037] S6. Holding the rear end of the vehicle pole 10 by hand, the curbstone 90 is pushed to the destination.
[0038] S7, lift the rear end of the vehicle bar 10 and make the head end of the vehicle bar 10 fall. When the curb 90 falls to the ground, the traction of the connecting ring 41 on the upper ends of the left clamp 50 and the right clamp 60 through the left rod 51 and the right rod 61 is weakened, and the support of the left clamping block 55 and the right clamping block 65 on the curb 90 becomes weaker.
[0039] S8. Manually move the upper ends of the left clamp 50 and the right clamp 60 outward, keep the left spring seat 53 and the left clamping block 55 in an open state, press down the rear end of the vehicle bar 10, and raise the head end of the vehicle bar 10 to raise the position of the clamp, release the support on the curb 90, and the operation is completed.
[0040] Features of this application:
[0041] S1. The utility model is provided with a clamp which can be automatically loosened, so that the loading and unloading of the curbstone is convenient and the workload of transporting the curbstone can be reduced.
[0042] S2. Part of the weight of the curb is converted into horizontal pressure on the curb by the left clamping block 55 and the right clamping block 65, so that the maximum static friction between the left clamping block 55 and the right clamping block 65 and the curb is larger, so that the clamp's support of the curb 90 is more stable.
[0043] S3. The oblique support can maintain the stability between the vehicle bar 10 and the vertical bar 20, and prolong the service life.
[0044] For other contents, please refer to the prior art.
[0045] The above-described embodiments are only preferred embodiments of the present invention. It should be noted that those skilled in the art may make several changes and improvements without departing from the overall concept of the present invention, and these should also be regarded as within the protection scope of the present invention.
