Description

Technical Field

[0001] The utility model relates to the technical field of curbstone construction, in particular to an auxiliary manual device for curbstone construction. Background Technique

[0002] In road construction, as an important facility for defining road boundaries, protecting road surfaces, and guiding drainage, the construction quality of curbstones is directly related to the overall aesthetics and functionality of the road. In order to improve the efficiency, precision, and safety of curbstone construction, a series of auxiliary manual devices are used to assist in the construction process.

[0003] In the existing curbstone construction process, equipment such as small forklifts, handcarts, or special handling racks are used for the short-distance handling of curbstones from the storage area to the construction site, reducing the labor intensity of workers and improving the handling efficiency. High-precision measuring instruments such as total stations, levels, and laser rangefinders are used to accurately measure the dimensions, elevations, and positions of curbstone installations in the construction area to ensure construction precision. Auxiliary devices such as curbstone clamps are also used. The curbstone clamp drives two clamping plates through a hydraulic system to clamp and fix the curbstone, and the fixed curbstone can be easily moved to the corresponding installation position by lifting equipment. All these devices used to assist manual labor in the curbstone construction process can be called an auxiliary manual device for curbstone construction.

[0004] In the installation construction of municipal road curbstones, when encountering larger-sized curbstones, relying on manual handling and adjustment by hand is very inefficient and extremely prone to injury. If relatively large mechanical equipment such as curbstone clamps is used, it will affect the installation accuracy. Moreover, when driving two clamping plates through a hydraulic system to clamp the curbstone, in order to prevent the fixed curbstone from falling off, the hydraulic system needs to be constantly activated, resulting in high energy consumption. Therefore, it does not meet the existing requirements, and for this reason, we propose an auxiliary manual device for curbstone construction. Content of the Utility Model

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0024] The tooth row 12 (model 5M-20), the threaded rod 15 (model M10), and the bevel gear A 17 (model LRGEA1.0) mentioned in the present invention can be obtained by purchasing from the market or customizing privately.

[0025] Please refer to Figures 1 to 4 , an embodiment provided by the present invention: a curb construction auxiliary manual device, including a portable curb clamp housing 1, an L-shaped plate 2 is provided behind the portable curb clamp housing 1, the front end of the L-shaped plate 2 is located inside the portable curb clamp housing 1, the outer surface of the L-shaped plate 2 located inside the portable curb clamp housing 1 is in contact with the inner wall of the portable curb clamp housing 1, and the portable curb clamp housing 1 and the L-shaped plate 2 are slidably connected;

[0026] On both sides of the front end face of the portable curb clamp housing 1, a rotating shaft connector 4 is connected, a cylindrical hollow housing 5 is fixedly provided on the front end face of the rotating shaft connector 4, a connecting plate 6 is fixedly provided on one side of the upper end face of the cylindrical hollow housing 5, and a manual pull rod 7 is fixedly provided between the two connecting plates 6;

[0027] A L-shaped claw 8 is slidably connected inside the cylindrical hollow housing 5, and a locking mechanism is provided between the two L-shaped claws 8. When the device needs to be used, the L-shaped plate 2 is buckled on the outer surface of the curb 9, and then the curb 9 is gently tilted. After the curb 9 is tilted, the bottom ends of the two L-shaped claws 8 are moved below the curb 9, and then the L-shaped claws 8 are directly pulled upward by the manual pull rod 7. Under the action of gravity, the L-shaped claws 8 will rotate around the pivot joint 4, so that the bottom ends thereof contact the lower end surface of the curb 9, thereby clamping the curb 9. Then, the staff uses the manual pull rod 7 on the device as a fulcrum to easily carry the curb 9. Through the above technical solution, the curb 9 can be clamped without using a hydraulic system, and the direction of the curb 9 can be adjusted more accurately and placed at the corresponding installation position.

[0028] On both sides of the upper end surface of the portable curb clamp housing 1, a bolt fixing head 3 is provided. The bolt fixing head 3 is connected to the portable curb clamp housing 1 through a threaded structure, and the lower end surface of the bolt fixing head 3 is in contact with the upper end surface of the L-shaped plate 2. By rotating the bolt fixing head 3 to release the contact between its lower end surface and the L-shaped plate 2, the fixing of the L-shaped plate 2 can be released. After the fixing of the L-shaped plate 2 is released, the L-shaped plate 2 can be moved back and forth to adapt the device to curbs 9 of different widths.

[0029] A connecting rod 11 is provided between the two L-shaped claws 8. On both sides of the outer surface of the connecting rod 11, a metal connecting sleeve 10 is sleeved, and the two metal connecting sleeves 10 are respectively fixed to the two L-shaped claws 8. The two L-shaped claws 8 can be connected by the metal connecting sleeve 10 and the connecting rod 11 to keep their relative positions. Through the above technical solution, the dislocation of their positions can be prevented.

[0030] The locking mechanism includes a strip-shaped plate 25. In the middle position above the strip-shaped plate 25, a manual rotating head 21 is provided. A locking head 22 is fixed to the outer side of the lower end surface of the manual rotating head 21. A locking groove 23 is provided on the upper end surface of the strip-shaped plate 25, and the outer surface of the locking head 22 is in contact with the inner wall of the locking groove 23. When it is necessary to change the length of the L-shaped claw 8 outside the cylindrical hollow housing 5 to adapt to curbs 9 of different heights, first move the manual rotating head 21 upward. As the manual rotating head 21 rises, the locking head 22 fixed to the lower end surface of the manual rotating head 21 will leave the inside of the locking groove 23. Only when the locking head 22 leaves the inside of the locking groove 23 can the manual rotating head 21 be rotated.

[0031] A square rod 20 is fixedly provided at the middle position of the lower end surface of the manual rotating head 21. An outer side of the square rod 20 is provided with a transmission rotating shaft 19 which is located inside the strip-shaped plate 25 and is connected to the strip-shaped plate 25 through a roller bearing. A square slot 24 is provided at the middle position of the upper end surface of the transmission rotating shaft 19, and the square rod 20 is inserted into the inside of the square slot 24. The cross-sectional shape of the inner wall of the square slot 24 is square. The outer surface of the square rod 20 is in fit with the inner wall of the square slot 24, and the square rod 20 is slidably connected with the square slot 24. When the locking head 22 leaves from the inside of the locking groove 23, manually rotate the manual rotating head 21. During the rotation of the manual rotating head 21, the square rod 20 fixed thereto will rotate together. Since the outer surface of the square rod 20 is in fit with the inner wall of the square slot 24 located at the upper end surface of the transmission rotating shaft 19, when the square rod 20 rotates, the transmission rotating shaft 19 will rotate together.

[0032] An umbrella gear B 18 is fixedly sleeved on the lower side of the outer surface of the transmission rotating shaft 19. The umbrella gear B 18 is engaged with an umbrella gear A 17. The axis of the umbrella gear A 17 is connected with a rotating shaft 14. Both ends of the rotating shaft 14 are fixedly connected with a threaded rod 15. An inner threaded sleeve 16 which is matched with the external thread thereof is sleeved on one side of the outer surface of the threaded rod 15, and the surface of the inner threaded sleeve 16 facing the nearest L-shaped claw 8 is slidably connected with the L-shaped claw 8. The rotating transmission rotating shaft 19 can drive the umbrella gear B 18 fixedly sleeved on the lower side of the outer surface of the transmission rotating shaft 19 and the umbrella gear A 17 engaged with the umbrella gear B 18 to rotate. The rotating umbrella gear A 17 can drive the rotating shaft 14 connected to the axis of the umbrella gear A 17 and the threaded rods 15 respectively connected to both ends of the rotating shaft 14 to rotate. Since the inner threaded sleeve 16 sleeved on the outer surface of the threaded rod 15 is slidably connected with the L-shaped claw 8, the inner threaded sleeve 16 itself cannot rotate. When the threaded rod 15 rotates, under the transmission of the thread structure, the inner threaded sleeve 16 which cannot rotate by itself will move back and forth on the outer surface of the threaded rod 15. At this time, move the inner threaded sleeve 16 towards the direction of the rotating shaft 14. During the movement of the inner threaded sleeve 16, the L-shaped claw 8 slidably connected therewith will move together.

[0033] On one side of the outer surface of the L-shaped claw 8, a row of teeth 12 is fixedly provided. The row of teeth 12 meshes with an arc-shaped head row of teeth 13 fixed to the inner wall of the cylindrical hollow housing 5, and the top end of the tooth head on the outer surface of the arc-shaped head row of teeth 13 is arc-shaped. When the L-shaped claw 8 moves in the direction of the rotation axis 14, the meshing between the row of teeth 12 fixed to its outer surface and the arc-shaped head row of teeth 13 will be released. After the meshing between the two is released, the L-shaped claw 8 can be manually moved up and down. When the L-shaped claw 8 located outside the cylindrical hollow housing 5 is adjusted to the corresponding length, rotate the manual rotation head 21 in the reverse direction to synchronously move the two L-shaped claws 8 outward. As the two L-shaped claws 8 move, the row of teeth 12 fixed to their outer surfaces will respectively mesh with the two arc-shaped head rows of teeth 13 again. If the tooth heads on the row of teeth 12 and the arc-shaped head row of teeth 13 directly collide, the row of teeth 12 can be slightly pushed through the arc-shaped tooth heads on the outer surface of the arc-shaped head row of teeth 13 to ensure that the two can mesh with each other. When the L-shaped claw 8 can no longer be moved outward, the L-shaped claw 8 will be fixed at the current position. After the L-shaped claw 8 is fixed, the locking head 22 on the lower end face of the manual rotation head 21 will move to a position corresponding to the locking groove 23, and then move the manual rotation head 21 downward to insert the locking head 22 into the locking groove 23 again to lock the fixed state of the L-shaped claw 8. Through the above technical solution, the situation that the L-shaped claw 8 is pushed downward due to the weight of the curbstone 9 being carried can be prevented.

Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting.
