DETAILED DESCRIPTION

[0033] In order for those skilled in the art to better understand the technical scheme of the utility model, the utility model will be further described in detail below in combination with the drawings.

[0034] Referring to Figs. 1-2 as shown;

[0035] The embodiment discloses a device for hoisting kerb stones, comprising:

[0036] Frame 1, the frame 1 both sides are provided with wheels 2, so that the device moves through the wheels 2, and the frame 1 serves as the main support structure of the device and is the main force bearing structure when hoisting kerb stones;

[0037] Top frame 3, the top frame 3 is arranged on the top of the frame 1;

[0038] Suspension beam 4, the suspension beam 4 is horizontally arranged above the top frame 3, and the middle position of the suspension beam 4 is rotatably connected with the top of the top frame 3, so that the two ends of the suspension beam 4 can swing under the support of the top frame 3, and the suspension beam 4 is used as a lever structure for hoisting kerb stones, and one end of the suspension beam 4 is provided with a cross beam 5;

[0039] Clamping mechanism, the clamping mechanism is symmetrically distributed on the two ends of the cross beam 5 and is suspended on the two ends of the cross beam 5, and the clamping mechanism is used for clamping the kerb stone when hoisting to hoist the kerb stone, and the clamping mechanism distributed on the two ends of the cross beam 5 can clamp the two end positions of the kerb stone respectively, so that the kerb stone can be smoothly hoisted; and

[0040] Hoisting driving mechanism, the hoisting driving mechanism is arranged between one end of the suspension beam 4 opposite to the clamping mechanism and the frame 1 and is used for driving the suspension beam 4 to rotate to drive the clamping mechanism to rise or fall, so that the suspension beam 4 is driven to rotate by the hoisting driving mechanism to realize hoisting, and manual labor is reduced.

[0041] Further, the frame 1 is provided with a sub-frame 6 on the side opposite to the clamping mechanism, and a universal wheel 7 is provided on the end of the sub-frame 6 opposite to the frame 1, so as to support the side opposite to the clamping mechanism, thereby stably supporting the clamping mechanism and the kerb clamped thereby.

[0042] Further, the clamping mechanism comprises a cross clamping rod 8 which is in the form of a scissor clamp with a rotating shaft at the middle part;

[0043] Two groups of clamping plates 9 are oppositely arranged on the inner sides of the two legs of the lower end of the cross clamping rod 8, and two suspension ropes 10 are connected to the two legs of the upper end of the cross clamping rod 8, and the upper ends of the two suspension ropes 10 are connected to the cross beam 5. The lower end of the cross clamping rod 8 in the form of a scissor clamp is used to clamp the kerb, and when the clamping mechanism is lifted, the cross clamping rod 8 is clamped to the kerb under the pulling of the two suspension ropes 10, and the two groups of clamping plates 9 are clamped on the two sides of the kerb to more stably clamp and lift the kerb. In addition, an anti-slip layer or a frosted layer can be arranged on the surface of the clamping plate 9 to improve the friction and more stably clamp the kerb.

[0044] Further, a blade-shaped bottom support 11 is arranged at the lower end of the clamping plate 9, which is used to support the bottom of the kerb when the cross clamping rod 8 clamps the kerb. Before the cross clamping rod 8 clamps the kerb, the blade-shaped bottom support 11 is inserted into the bottom of the kerb, and after clamping, the kerb is lifted. The blade-shaped bottom support 11 can support the bottom of the kerb.

[0045] Further, a pre-clamping positioning mechanism is arranged at the upper end of the cross clamping rod 8, which is used to pre-clamp the kerb when the cross clamping rod 8 is not lifted. The pre-clamping positioning mechanism comprises a first internally threaded pipe 12 and a first threaded rod 13, and the first threaded rod 13 is arranged in the first internally threaded pipe 12 and threadedly connected with the first internally threaded pipe 12.

[0046] The two legs of the upper end of the cross clamping rod 8 are provided with a first strip-shaped hole 14 through which the first threaded rod 13 passes, and the length of the first strip-shaped hole 14 is greater than the diameter of the first threaded rod 13.

[0047] A top plate 15 is arranged on the first internally threaded pipe 12 and the first threaded rod 13.

[0048] When the first threaded rod 13 passes through the first slotted hole 14 at the upper end of the cross clamp 8 and is threadedly tightened with the first internally threaded tube 12, the two sets of top plates 15 on the first internally threaded tube 12 and the first threaded rod 13 respectively press against both sides of the upper end of the cross clamp 8. That is, the threaded tightening of the first slotted hole 14 with the first internally threaded tube 12 allows the top plates 15 on the first internally threaded tube 12 and the first threaded rod 13 to press against both sides of the upper end of the cross clamp 8. Gradually tightening the first internally threaded tube 12 and the first threaded rod 13 causes the two sets of top plates 15 to continuously press against the cross clamp 8, thereby allowing the cross clamp 8 to be pre-clamped and fixed on the curb stone. During the subsequent lifting process, this prevents the cross clamp 8 from slipping on the curb stone, thus stabilizing the lifting of the curb stone. The first internal threaded tube 12, the first threaded rod 13, and the top plate 15 are located on both sides of the cross clamping rod 8, which will not affect the clamping action of the cross clamping rod 8. The first strip hole 14 allows the first threaded rod 13 to pass through, and the length of the first strip hole 14 is greater than the diameter of the first threaded rod 13. The top plate 15 cannot pass through the first strip hole 14, and will not be restricted or jammed by the first threaded rod 13 in the first strip hole 14 during the rotation of the cross clamping rod 8.

[0049] Furthermore, the outer sides of the two legs at the upper end of the cross clamp 8 are spherical, and the side of the top plate 15 facing the cross clamp 8 is also spherical, so that the outer sides of the two legs at the upper end of the cross clamp 8 and the top plate 15 are in spherical contact, and the force application effect will not be affected by the change of angle during the cross clamp 8's cross rotation.

[0050] Furthermore, a connecting rope 16 is provided between the first internally threaded pipe 12 and the frame 1. The connecting rope 16 can be made of nylon rope or chain. In order to help limit the clamping mechanism and prevent the clamping mechanism from shaking violently and injuring people during the transportation of curb stones, the stability of the hoisting is improved.

[0051] Furthermore, the lifting drive mechanism includes a second internal threaded tube 17 and a second threaded rod 18. The second internal threaded tube 17 is vertically fixed on the sub-frame 6. A second strip hole 19 is provided on one end of the lifting beam 4 opposite to the crossbeam 5. The second threaded rod 18 passes through the second strip hole 19 and is inserted into the second internal threaded tube 17. The second threaded rod 18 and the second internal threaded tube 17 are threadedly engaged.

[0052] The upper end of the second threaded rod 18 is fixedly provided with a pressure plate 20 that presses against the upper surface of the lifting beam 4, and a rotating wheel 21 is provided at the upper end of the second threaded rod 18 and above the pressure plate 20.

[0053] Specifically, after the clamping mechanism pre-clamps the curbstone, the second threaded rod 18 is manually driven to rotate by rotating the wheel 21, and when threadedly matched with the fixed position second internal threaded tube 17, the second threaded rod 18 moves axially, and then drives the pressing plate 20 to move downward, at the same time, the hanging beam 4 is pressed downward to drive the hanging beam 4 to rotate, and drive the clamping mechanism to lift and hoist the curbstone. Conversely, the second threaded rod 18 is reversely rotated, and the curbstone is lowered.

[0054] Further, the counterweight 22 is arranged on one end of the hanging beam 4 opposite to the cross beam 5, the counterweight 22 balances the stress of the hanging beam 4, so that the weight of the curbstone can be stably borne, and the curbstone is lifted and hoisted more labor-saving.

[0055] In the above technical solution, the device for hoisting curbstone has the following beneficial effects:

[0056] The clamping mechanism is used for clamping the curbstone, and before the clamping mechanism hoists the curbstone, the clamping mechanism can pre-clamp the curbstone first, and then lift, so that the clamping mechanism is prevented from sliding on the curbstone or sliding too much during hoisting, and the hoisting of the curbstone is stabilized, and the use safety of the lifting device is improved.

[0057] The above only describes some exemplary embodiments of the device for hoisting curbstone by way of illustration, and it is needless to say that the described embodiments can be modified in various ways without departing from the spirit and scope of the device for hoisting curbstone. Therefore, the above drawings and description are illustrative in nature, and should not be understood as limiting the scope of protection of the device for hoisting curbstone.
