Description

Technical Field

[0001] This invention relates to the field of curbstone laying technology, specifically a foldable curbstone laying machine. Background Technology

[0002] Curbstones are marker stones placed between the road surface and other structures. They are generally required between the median strip and the road surface in urban roads, and between the sidewalk and the road surface. They are also commonly found at the edges of the central median strip, the right edge of the driving lane, or the outer edge of the shoulder on highways. To reduce the labor intensity of workers and improve the safety of paving, paving machines are now commonly used in the paving of curbstones.

[0003] Existing curbstone laying machines are generally equipped with forklifts to transport curbstones. By controlling the position of the forklifts, adjacent curbstones are aligned and connected end to end to ensure neatness. However, using external large forklifts and other engineering vehicles to determine the installation position of the curbstones requires a lot of time for debugging in the early stage, which is quite time-consuming. In addition, the data obtained by visual observation has a certain error rate. If the curbstone is crooked after the equipment is placed, it still needs to be adjusted again. The overall practicality of the equipment during operation is low.

[0004] To address this, we have developed a new type of foldable curbstone laying machine. Summary of the Invention

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this invention provides a foldable curbstone laying machine, which solves the problems of the existing methods that require a lot of time for debugging in the early stages when determining the installation position of curbstones by using external large forklifts and other engineering vehicles, which is time-consuming and the data obtained by visual observation has a certain error rate. If the curbstone is tilted after the equipment is put down, it still needs to be adjusted again, resulting in low practicality.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, the present invention is implemented through the following technical solution: a foldable curbstone laying machine, including a base, an installation cavity is provided inside the base, a positioning mechanism is installed on the left side wall of the installation cavity, and a driving mechanism that cooperates with the positioning mechanism is installed inside the installation cavity;

[0009] One end of the upper surface of the machine base is symmetrically hinged with support rods, and a first hydraulic cylinder is hinged to the upper surface of the machine base. The piston end of the first hydraulic cylinder is hinged to the lower surface of a single support rod.

[0010] A crossbeam is fixedly connected to the opposite sides of the two support rods. A longitudinal moving mechanism is installed on the lower surface of the crossbeam. A connecting plate is slidably connected to the upper surface of the longitudinal moving mechanism. A transverse moving mechanism that cooperates with the connecting plate is installed at one end of the longitudinal moving mechanism. A clamping assembly is installed at one end of the connecting plate.

[0011] Preferably, the positioning mechanism includes a T-shaped abutment plate slidably connected to the left side wall of the mounting cavity, one end of the T-shaped abutment plate extending through to the bottom of the mounting cavity, and an L-shaped fixing plate fixedly connected to one side of the outer surface of the T-shaped abutment plate, a support plate fixedly connected to the lower surface of the L-shaped fixing plate, and a rubber pad fixedly connected to the lower surface of the support plate.

[0012] Preferably, the drive mechanism includes a first motor fixedly mounted on the upper surface of the base, the output shaft of the first motor extending through into the interior of the mounting cavity and fixedly connected to a first lead screw, a sliding plate being threadedly connected to the outer surface of the first lead screw, the outer surface of the sliding plate being slidably connected to the inner wall of the mounting cavity, and one end of the sliding plate being fixedly connected to the top of the outer surface of the L-shaped fixing plate.

[0013] Through the above technical solution, the operation of the first motor can drive the slide plate to slide along the inner wall of the mounting cavity through the first lead screw, thereby driving the T-shaped abutment plate and the support plate to move downward. The T-shaped abutment plate can fit against the edge of the road surface, and the support plate can fit against the road surface, thereby achieving the positioning of the entire equipment.

[0014] Preferably, the longitudinal moving mechanism includes electric push rods symmetrically fixedly installed on the lower surface of the crossbeam and two slide rails respectively fixedly connected to one side of the outer surface of the two support rods. The output ends of the two electric push rods are jointly fixedly connected to a mounting base, and the inner sides of both ends of the mounting base are slidably connected to the corresponding slide rails.

[0015] With the above technical solution, the extension and retraction of the output end of the electric push rod can drive the mounting base to slide along the two slide rails, so that the connecting plate can change its longitudinal height as the mounting base slides.

[0016] Preferably, the lateral movement mechanism includes a mounting plate fixedly connected to one end of the mounting base. A second motor is fixedly mounted on the front side of the mounting plate. A second lead screw is fixedly connected to the output shaft of the second motor. A threaded sleeve is threaded onto the outer surface of the second lead screw, and one end of the threaded sleeve is fixedly connected to one end of the connecting plate.

[0017] Preferably, the clamping assembly includes an extension plate symmetrically hinged to one end of a connecting plate and a second hydraulic cylinder hinged to the other end of the upper surface of the connecting plate. The tops of the two extension plates are fixedly connected to a connecting rod, and the piston end of the second hydraulic cylinder is hinged to one side of the outer surface of the connecting rod. The inner sides of the two extension plates are fixedly connected to a first clamping plate, and one end of the lower surface of the connecting plate is fixedly connected to a second clamping plate that cooperates with the first clamping plate.

[0018] Through the above technical solution, the extension and retraction of the piston end of the second hydraulic cylinder can effectively drive the two extension plates to rotate around the end of the connecting plate. When the two first clamping plates rotate to a certain angle and cooperate with the second clamping plate, the curb stone can be clamped.

[0019] Preferably, both extension plates are fixedly connected to the connecting rod by a reinforcing plate.

[0020] The above technical solution, through the setting of the reinforcing plate, can enhance the strength and rigidity of the extension plate, and ensure the reliability of the extension plate and the first clamping plate during use.

[0021] Preferably, the inner sides of both first clamping plates and the single second clamping plate are provided with anti-slip texture.

[0022] Through the above technical solution, the anti-slip texture can enhance the friction between the curbstone and the two first clamping plates and the single second clamping plate, making the clamping more powerful.

[0023] Preferably, wheels are symmetrically fixedly installed on both the front and back of the base, and a handle is fixedly connected to one end of the upper surface of the base.

[0024] Using the above technical solution, by holding the handle and coordinating with the rotation of the wheels, the entire device can be moved to a suitable location for laying the curbstone.

[0025] Preferably, the bottom sidewall of the mounting cavity has a slot that matches the support plate and the T-shaped abutment.

[0026] (III) Beneficial Effects

[0027] This invention provides a foldable curbstone laying machine. It has the following advantages:

[0028] 1. This foldable curbstone laying machine, through the design of a positioning mechanism, when the machine base moves to the installation position of the curbstone and is close to the curb, the operation of the first motor can drive the T-shaped support plate and the support plate to extend downward into the installation cavity through the sliding plate. By observing whether the support plate is in contact with the curb, it can be determined whether the entire equipment is flush with the curb, thereby ensuring the uniformity of the curbstone during subsequent laying and avoiding inaccurate data obtained by visual observation that would cause the curbstone to be laid crookedly. It is highly practical.

[0029] 2. This foldable curbstone laying machine, through the design of a lateral movement mechanism, when the curbstone falls to almost touching the ground, controls the operation of the second motor to drive the threaded sleeve and even the connecting plate to make a fine adjustment in the lateral distance, so that the two adjacent curbstones can be connected end to end. The entire curbstone laying process does not require a lot of time to be spent on debugging in the early stage, which saves construction time and improves construction efficiency.

[0030] 3. This foldable curbstone laying machine, through the design of a first hydraulic cylinder and two support rods, not only has a simple structure, but also enables the support rods to be folded close to the machine base, thereby reducing the space occupied by the overall equipment and facilitating the transportation of the entire equipment during construction.

[0039] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0040] Example:

[0041] like Figure 1-7 As shown, this embodiment of the invention provides a foldable curbstone laying machine, including a base 1. Wheels 2 are symmetrically fixedly mounted on both the front and back of the base 1, and a handle 3 is fixedly connected to one end of the upper surface of the base 1. An installation cavity 24 is formed inside the base 1. A positioning mechanism is installed on the left side wall of the installation cavity 24, and a drive mechanism cooperating with the positioning mechanism is installed inside the installation cavity 24. Support rods 5 are symmetrically hinged to one end of the upper surface of the base 1, and a first hydraulic cylinder 4 is hingedly mounted on the upper surface of the base 1. The piston end of the first hydraulic cylinder 4 is connected to the lower end of a single support rod 5. The surfaces are hinged together. By controlling the extension and retraction of the first hydraulic cylinder 4, the angle of rotation of the support rod 5 around the base 1 can be controlled, so as to realize the folding of the support rod 5 to facilitate the transportation of the whole equipment, or to lay the curb stone perpendicular to the base 1. The two support rods 5 are fixedly connected to the opposite side of the crossbeam 6. The lower surface of the crossbeam 6 is equipped with a longitudinal moving mechanism. The upper surface of the longitudinal moving mechanism is slidably connected with a connecting plate 10. One end of the longitudinal moving mechanism is equipped with a transverse moving mechanism that cooperates with the connecting plate 10. One end of the connecting plate 10 is equipped with a clamping component.

[0042] like Figure 2 and 3 As shown, the positioning mechanism includes a T-shaped abutment 23 slidably connected to the left side wall of the mounting cavity 24. One end of the T-shaped abutment 23 extends through to the bottom of the mounting cavity 24, and an L-shaped fixing plate 20 is fixedly connected to one side of the outer surface of the T-shaped abutment 23. A support plate 21 is fixedly connected to the lower surface of the L-shaped fixing plate 20, and a rubber pad 22 is fixedly connected to the lower surface of the support plate 21. The bottom side wall of the mounting cavity 24 has a slot 30 that matches the support plate 21 and the T-shaped abutment 23. The slot 30 allows the bottom of the support plate 21 and the T-shaped abutment 23 to pass through. When the support plate 21 moves downward, it will pass through the slot 30 and extend to the bottom of the base 1. However, after the two move downward a certain distance, the top of the T-shaped abutment 23 will abut against the bottom of the inner wall of the mounting cavity 24, thereby preventing the two from slipping off.

[0043] like Figure 3As shown, the drive mechanism includes a first motor 17 fixedly mounted on the upper surface of the base 1. The output shaft of the first motor 17 extends through into the interior of the mounting cavity 24 and is fixedly connected to a first lead screw 18. A sliding plate 19 is threadedly connected to the outer surface of the first lead screw 18. The outer surface of the sliding plate 19 is slidably connected to the inner wall of the mounting cavity 24, and one end of the sliding plate 19 is fixedly connected to the top of the outer surface of the L-shaped fixing plate 20. The operation of the first motor 17 will drive the rotation of the first lead screw 18, thereby causing the sliding plate 19 to slide along the inner wall of the mounting cavity 24, driving the L-shaped fixing plate 20 connected to it to move downward.

[0044] like Figure 4 and 5 As shown, the longitudinal moving mechanism includes electric push rods 7 symmetrically fixedly installed on the lower surface of the crossbeam 6 and two slide rails 9 respectively fixedly connected to one side of the outer surface of the two support rods 5. The output ends of the two electric push rods 7 are fixedly connected to the mounting base 8, and the inner sides of both ends of the mounting base 8 are slidably connected to the corresponding slide rails 9. The extension and retraction of the output ends of the electric push rods 7 will drive the mounting base 8 to slide along the two slide rails 9, so that the connecting plate 10 connected to the mounting base 8 will rise and fall in longitudinal height.

[0045] like Figure 6 As shown, the lateral movement mechanism includes a mounting plate 25 fixedly connected to one end of the mounting base 8. A second motor 26 is fixedly mounted on the front of the mounting plate 25. A second lead screw 27 is fixedly connected to the output shaft of the second motor 26. A threaded sleeve 28 is threadedly connected to the outer surface of the second lead screw 27, and one end of the threaded sleeve 28 is fixedly connected to one end of the connecting plate 10. The operation of the second motor 26 can drive the rotation of the second lead screw 27, thereby controlling the threaded sleeve 28 and causing the connecting plate 10 to slide laterally on the upper surface of the mounting base 8, thus achieving fine adjustment.

[0046] like Figure 1 and 7As shown, the clamping assembly includes extension plates 13 symmetrically hinged to one end of the connecting plate 10 and a second hydraulic cylinder 11 hinged to the other end of the upper surface of the connecting plate 10. A connecting rod 12 is fixedly connected to the top of both extension plates 13. A reinforcing plate 14 is fixedly connected between both extension plates 13 and the connecting rod 12. The piston end of the second hydraulic cylinder 11 is hinged to one side of the outer surface of the connecting rod 12. A first clamping plate 15 is fixedly connected to the inner side of both extension plates 13. A reinforcing plate 14 is fixedly connected to one end of the lower surface of the connecting plate 10. The second clamping plate 16, which cooperates with the first clamping plate 15, will cause the piston end of the second hydraulic cylinder 11 to extend and retract, thereby causing the connecting rod 12 connected to it to change position, thereby causing the extension plate 13 to rotate around the end of the connecting plate 10. When the extension plate 13 rotates to a certain angle, the curb stone can be clamped by the cooperation between the first clamping plate 15 and the second clamping plate 16. The inner sides of the two first clamping plates 15 and the single second clamping plate 16 are provided with anti-slip textures 29 to increase the friction between the first clamping plate 15 and the second clamping plate 16 and the outer surface of the curb stone.

[0047] Working Principle: By designing the first hydraulic cylinder 4 and two support rods 5, the structure is not only simple but also allows the support rods 5 to be folded close to the base 1, thereby reducing the space occupied by the overall equipment and facilitating the transportation of the entire equipment during construction. When it is necessary to lay the curbstone, first push the handle 3 to move the entire equipment next to the curbstone. Start the first hydraulic cylinder 4, braking the piston end of the first hydraulic cylinder 4 to extend, so that the support rod 5 is in a perpendicular state to the base 1. Then start the second hydraulic cylinder 11, controlling the piston end of the second hydraulic cylinder 11 to extend, causing the extension plate 13 and even the two first clamping plates 15 to rotate, cooperating with the second clamping plate 16 to clamp the curbstone. Then, the electric push rod 7 can be braked, causing its output end to retract and drive the mounting base 8 and the curbstone to rise. Then, by visual inspection, the entire equipment is initially moved to the curb position. When the base 1 is moved to the appropriate installation position of the curbstone and close to the curbstone, the first motor 17 is started. The operation of the first motor 17 can be driven by the sliding plate 19. The T-shaped abutment plate 23 and support plate 21 extend downwards into the mounting cavity 24. By determining whether the support plate 21 is in contact with the curb, it can be determined whether the entire device is flush with the curb. Then, the handle 3 can be pushed to move the base 1, so that the support plate 21 is in contact with the curb. Then, the first motor 17 is braked to continue driving the T-shaped abutment plate 23 and support plate 21 to move downwards until the support plate 21 is in close contact with the road surface, thereby achieving the positioning of the entire device and ensuring the uniformity of the subsequent curb stones during laying. This avoids the inaccuracy of data obtained by visual observation, which may cause the curb stones to be laid crookedly. It is highly practical. The electric push rod 7 is braked, so that its output end drives the mounting base 8 and causes the curb stone to fall. When the curb stone falls to almost touching the ground, the operation of the second motor 26 is controlled to drive the threaded sleeve 28 and the connecting plate 10 to make a fine adjustment in the lateral distance, so that the ends of two adjacent curb stones can be connected. The entire curb stone laying process does not require a lot of time for debugging in the early stage, which saves construction time and improves construction efficiency.

[0048] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
