Detailed Implementation

[0023] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] As attached Figure 1 , Figure 3 As shown, a hand-cranked curbstone installation vehicle includes a V-shaped base 3, a column 6, a self-locking hand-cranked winch 7, an upper crossbeam 8, a first pulley 9, a second pulley 10, a lifting line 11, a pulley block 12, a support rod 13, a reinforcing rod 14, a rotating base 15, a counterweight 16, and a curbstone clamp 1. Wherein:

[0025] The bottom of the V-shaped base 3 is equipped with two universal wheels 5, the front end is equipped with two rubber front wheels 4, and the top is equipped with a rotating base 15 and a counterweight 16.

[0026] The bottom of the column 6 is installed on the upper surface of the rotating base 15, and a self-locking hand-cranked winch 7 is installed on one side of the middle part of the column 6.

[0027] One end of the upper crossbeam 8 is connected to the top of the column 6, and the other end of the upper crossbeam 8 is suspended. The upper two ends of the upper crossbeam 8 are respectively provided with a first pulley 9 and a second pulley 10. The first pulley 9 is close to the top of the column 6, and the second pulley 10 is close to the suspended end.

[0028] One end of the lifting line 11 is fixed to the self-locking hand-cranked winch 7, and the other end of the lifting line 11 passes through the first pulley 9 and the second pulley 10 in sequence and is connected to the pulley block 12. The curb clamp 1 is installed under the pulley block 12.

[0029] The V-shaped base 3, column 6, support rod 13, and upper crossbeam 8 are all made of 10# channel steel, 110*10 square steel, or steel plate.

[0030] The lifting line 11 is a steel wire rope with a diameter of 8mm or 10mm.

[0031] As attached Figure 6As shown, the two L-shaped clamping arms 101 of the curb clamp 1 are connected by a rotating shaft, which can be conveniently opened or folded. The anti-skid rubber clamping disc 102 can increase the friction between the clamp and the curb, avoiding the curb from falling off during the carrying process, and the safety and portability are good.

[0032] As shown in the accompanying drawings, Figure 4 、 Figure 5 As shown in the accompanying drawings, the self-locking hand winch 7 includes a brake limiting disc 701, a rotating shaft disc 702, a crank handle transmission gear 703 and a cover plate 704. The two shaft ends of the rotating shaft disc 702 are respectively provided with the cover plate 704, which can be used to limit the axial displacement of the hoisting line 11 wound on the rotating shaft of the rotating shaft disc 702, avoiding the hoisting line 11 from falling off the shaft end of the rotating shaft disc 702. The brake limiting disc 701 is eccentrically arranged on the rotating shaft disc 702, and has a certain thickness and rotates with the rotating shaft disc 702. The brake limiting disc 701 can be a horizontally arranged semicircular disc. When the semicircular disc rotates to the outside of the rotating shaft disc 702, if the rotating shaft disc 702 continues to rotate, the semicircular disc is blocked by the cover plate 704, limiting the continuous rotation of the rotating shaft disc 702. If the semicircular disc is rotated by 180 degrees to protrude to the inside of the rotating shaft disc, the semicircular disc no longer hinders the rotation of the rotating shaft disc 702. This improved design ensures the convenience and safety of the hand-operated curb installation vehicle during use. Especially when carrying heavy objects or operating on a slope, the automatic locking function can effectively prevent accidents and protect the safety of the operator and the equipment.

[0033] Of course, the self-locking hand winch 7 of the present embodiment can also use the existing structure. The rotating shaft disc 702 includes a worm gear and a rotating shaft arranged at the center of the worm gear, and the crank handle transmission gear 703 includes a worm, which cooperates with the worm gear to form a self-locking worm and gear mechanism. Among them, the rotating shaft at the center of the worm gear is used for winding the hoisting line 11, and the two ends of the rotating shaft are connected with the cover plate 704. The operator drives the crank handle transmission gear 703 by rotating the crank handle 2 to drive the rotating shaft disc 702 to pull the heavy object with the hoisting line 11.

[0034] As shown in the accompanying drawings, Figure 2As shown, the outer arm 801 of the upper crossbeam has four limiting holes 802, and the inner arm 803 of the upper crossbeam has one limiting hole 802. Pins are inserted into different limiting holes 802 to correspond to the maximum load settings of 1000kg, 800kg, 600kg, and 400kg. By setting limiting holes on the upper crossbeam 802, a multi-level load adjustment function for the hand-cranked curbstone installation cart is achieved. This allows operators to flexibly adjust the maximum load capacity of the installation cart according to actual needs to adapt to the handling requirements of curbstones of different weights. At the same time, the multi-level load adjustment function also helps protect the structural strength of the installation cart and extend its service life, avoiding equipment damage or safety accidents caused by overloading. In actual operation, operators only need to select the appropriate load setting according to the weight of the curbstone to easily complete the handling task.

[0035] As attached Figure 1 , Figure 3 As shown, the V-shaped base 3 serves as the supporting foundation for the entire installation vehicle. Its bottom is equipped with omnidirectional guide wheels 5, and its front rubber wheels 4 allow the installation vehicle to move flexibly on different terrains and adapt to various road conditions. Simultaneously, the upper part of the V-shaped base 3 is also equipped with a rotating base 15 and a counterweight 16, making the curbstone installation vehicle more flexible and usable. Furthermore, the counterweight 16 helps maintain the stability and balance of the installation vehicle, ensuring safety during operation.

[0036] The column 6 is mounted on the upper surface of the V-shaped base 3, serving to support and secure other components. A self-locking hand-cranked winch 7 is installed on one side of the middle of the column 6; this is the power source for the entire installation vehicle. By cranking the handle 2, the self-locking hand-cranked winch 7 can be rotated, thereby driving the lifting line 11 to move up and down, thus achieving the lifting and movement of the curb stones.

[0037] The upper crossbeam 8 is connected to the top of the column 6 and suspended at the other end. This design ensures the stability of the installation and provides sufficient operating space for the installation vehicle. At the upper ends of the upper crossbeam 8, a first pulley 9 and a second pulley 10 are respectively provided. Together, they form the guiding system of the lifting line 11, ensuring that the lifting line 11 can move along the predetermined path.

[0038] One end of the lifting line 11 is fixed to the self-locking hand-cranked winch 7, and the other end passes through the first pulley 9 and the second pulley 10 in sequence and connects to the pulley block 12. The pulley block 12 includes one upper and one lower hook, as well as three fixed pulleys and three movable pulleys. This design can greatly increase the load-bearing capacity of the lifting line while reducing friction, making the lifting process smoother. Below the pulley block 12, a curb clamp 1 is installed, which can firmly clamp the curb stone to ensure that the curb stone will not fall off or wobble during lifting and movement.

[0039] The installation vehicle also adopts various reinforcing and stabilizing designs. For example, the V-shaped base 3, the column 6, the support rod 13 and the upper cross beam 8 are all made of high-strength materials to ensure the structural strength and durability of the entire installation vehicle. Meanwhile, a reinforcing rod 14 is arranged between the bottom of the column 6 and the V-shaped base 3 to further enhance the stability of the installation vehicle.

[0040] In the specific operation process, the operator only needs to shake the handle 2 to drive the self-locking hand winch 7 to rotate, so as to drive the pulley block 12 and the curbstone clamp 1 to move up and down through the lifting line 11. When it is needed to move the curbstone, the operator only needs to clamp the curbstone with the curbstone clamp 1, and then shake the handle 2 to make the lifting line 11 rise, so as to lift the curbstone. Then, the operator can push the installation vehicle to the target position. During the movement, the universal guide wheel 5 and the rubber front wheel 4 can ensure the flexible driving and steering of the installation vehicle on the narrow road. After reaching the specified position, the operator rotates the handle 2 again to install the curbstone in place. During the entire process, the self-locking hand winch 7 and the pulley block 12 and other components work cooperatively to ensure the stability and safety of lifting and movement. Meanwhile, the support rod 13 and the reinforcing rod 14 and other components can effectively increase the structural strength and stability of the installation vehicle to bear larger load and impact force.

[0041] As shown in the accompanying drawings, Figure 6 The curbstone clamp 1 is composed of two L-shaped clamp arms 101 connected through a rotating shaft, so that the clamp can be conveniently opened or folded to adapt to curbstones of different sizes. Meanwhile, anti-skid rubber clamping discs 102 are arranged on the L-shaped clamp arms 101, which can increase the friction between the clamp and the curbstone, so as to effectively prevent the curbstone from falling off during the carrying process, and improve the safety and portability of the carrying. The operator only needs to control the opening and folding of the curbstone clamp 1 to easily clamp and release the curbstone, which greatly improves the carrying efficiency. Meanwhile, the design of the anti-skid rubber clamping discs 102 also ensures the stability of the curbstone during the carrying process, and reduces the operation risk.

[0042] The above is only the preferred embodiment of the present application, and the protection scope of the present application is not limited to the above-mentioned embodiments. Any technical solution falling within the idea of the present application shall fall within the protection scope of the present application. It should be noted that, for ordinary technical personnel in the technical field, some improvements and decorations without departing from the principle of the present application shall also be considered as the protection scope of the present application.
