Description

Technical Field

[0001] This utility model relates to the field of road closure machine technology, specifically to a lifting mechanism for a liftable road closure machine. Background Technology

[0002] As a core piece of equipment for traffic control and safety protection, road closure machines are widely used in various scenarios: during road construction, it is necessary to temporarily close half or the entire road surface to prevent social vehicles from entering the construction area and causing safety accidents; during large-scale events (such as marathons and concerts), it is necessary to implement time-sharing control of core road sections to ensure unimpeded evacuation channels; in emergency rescue scenarios (such as fires and traffic accidents), it is necessary to quickly block the passage of non-rescue vehicles to open up "life channels" for rescue vehicles; in addition, places such as residential areas, industrial parks, and toll stations often use road closure machines to achieve precise management of entrances and exits and restrict the entry of vehicles that violate regulations.

[0003] Existing road sealing machines generally have a simple structure, requiring the height of the stop bar to be adjusted in advance using multiple sets of bolts. Furthermore, the stop bar is usually designed as a single piece, which cannot flexibly adapt to different practical scenarios. The inability to disassemble and assemble the machine leads to inconvenience in transporting and maintaining it. Therefore, this utility model provides a lifting mechanism for a liftable road sealing machine. Utility Model Content

[0004] In view of the shortcomings of the existing technology, this utility model provides a lifting mechanism for a liftable road sealing machine, which solves the problems of insufficient adaptability and inconvenient disassembly and maintenance of the existing road sealing machine.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a lifting mechanism for a liftable road sealing machine, including a base, wherein the interior of the base drives a support column to rotate through a rotating component, the interior of the support column drives a connecting seat to rise and fall through a lifting component, a main stop rod is installed inside the connecting seat through connecting bolts, an assembly groove is provided at one end of the main stop rod, and a secondary stop rod is installed at one end of the main stop rod through an assembly component;

[0006] The lifting assembly includes a lifting motor installed inside the support column. One end of the output shaft of the lifting motor is fixedly connected to a lifting screw via a coupling. One end of the lifting screw is rotatably connected to the top of the inner cavity of the support column. A cross plate is threaded onto the surface of the lifting screw, and the surface of the cross plate is fixedly connected to the inner wall of the connecting seat.

[0007] Preferably, the surface of the support column is provided with a lifting groove, and the inner surface of the lifting groove is slidably connected to the surface of the cross plate.

[0008] Preferably, the assembly assembly includes an assembly block adapted to the assembly slot, the assembly block has an internal threaded connection to an assembly bolt, the surface of the assembly bolt is threaded to the bottom of the main stop rod, and one side of the assembly block is fixedly connected to one end of the auxiliary stop rod.

[0009] Preferably, the rotating assembly includes a rotating motor installed at the bottom of the base cavity, one end of the output shaft of the rotating motor is fixedly connected to a rotating bevel gear via a coupling, and the surface of the rotating bevel gear drives the support column to rotate via a linkage assembly.

[0010] Preferably, the linkage assembly includes a linkage shaft installed at the bottom of the support column. The surface of the linkage shaft is rotatably connected to the interior of the base. The linkage shaft extends into the inner cavity of the base and is fixedly connected to a linkage bevel gear. The surface of the linkage bevel gear meshes with the surface of the rotating bevel gear.

[0011] Preferably, a monitoring camera is installed on the top of the base, and multiple sets of reflective stickers are installed on the surfaces of the main lever and the auxiliary lever.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 This utility model provides a technical solution:

[0023] A lifting mechanism for a liftable road sealing machine includes a base 1. Inside the base 1, a rotating component 2 drives a support column 3 to rotate. Inside the support column 3, a lifting component 4 drives a connecting seat 5 to rise and fall. Inside the connecting seat 5, a main stop bar 7 is installed through a connecting bolt 6. One end of the main stop bar 7 has an assembly groove 8. One end of the main stop bar 7 is installed with a secondary stop bar 10 through an assembly component 9.

[0024] The lifting assembly 4 includes a lifting motor 41 installed inside the support column 3. One end of the output shaft of the lifting motor 41 is fixedly connected to a lifting screw 42 via a coupling. One end of the lifting screw 42 is rotatably connected to the top of the inner cavity of the support column 3. A cross plate 43 is threadedly connected to the surface of the lifting screw 42. The surface of the cross plate 43 is fixedly connected to the inner wall of the connecting seat 5.

[0025] The connecting seat 5 is sleeved on the surface of the support column 3 and slides on its surface;

[0026] The lifting motor 41 is a three-phase asynchronous motor;

[0027] The lifting assembly 4 enables stable lifting of the main and auxiliary levers. The lifting motor 41 drives the lifting screw 42 to rotate, which in turn drives the cross plate 43 and the connecting seat 5 to rise and fall. The lifting groove 11 limits the movement of the cross plate 43, improving the stability and accuracy of the lifting process. The main lever 7 and the auxiliary lever 10, as well as the auxiliary lever 10 and the auxiliary lever 10, are connected by the assembly assembly 9. The assembly block 91 is fixed by the assembly bolt 92 after it is engaged with the assembly groove 8, which facilitates quick assembly and disassembly and reduces the difficulty of transportation and maintenance.

[0028] In this embodiment, the surface of the support column 3 is provided with a lifting groove 11, and the inner surface of the lifting groove 11 is slidably connected to the surface of the cross plate 43.

[0029] The lifting groove 11 is used to limit the up and down sliding of the cross plate 43;

[0030] In this embodiment, the assembly component 9 includes an assembly block 91 that is adapted to the assembly groove 8. The assembly block 91 is internally threaded with an assembly bolt 92. The surface of the assembly bolt 92 is threadedly connected to the bottom of the main stop bar 7. One side of the assembly block 91 is fixedly connected to one end of the auxiliary stop bar 10.

[0031] Multiple sets of auxiliary levers 10 are provided, and an assembly block 91 is installed at one end of each set of auxiliary levers 10. An assembly groove is opened at the other end of each set of auxiliary levers 10, and a sealing element is adapted to the assembly groove at the other end of the last auxiliary lever 10.

[0032] In this embodiment, the rotating assembly 2 includes a rotating motor 21 installed at the bottom of the inner cavity of the base 1. One end of the output shaft of the rotating motor 21 is fixedly connected to a rotating bevel gear 22 via a coupling. The surface of the rotating bevel gear 22 drives the support column 3 to rotate via the linkage assembly 23.

[0033] Rotary motor 21 is a three-phase asynchronous motor;

[0034] In this embodiment, the linkage assembly 23 includes a linkage shaft 231 installed at the bottom of the support column 3. The surface of the linkage shaft 231 is rotatably connected to the interior of the base 1. The linkage shaft 231 extends into the inner cavity of the base 1 and is fixedly connected to a linkage bevel gear 232. The surface of the linkage bevel gear 232 meshes with the surface of the rotating bevel gear 22.

[0035] In this embodiment, a monitoring camera 12 is installed on the top of the base 1, and multiple sets of reflective stickers are installed on the surfaces of the main lever 7 and the auxiliary lever 10.

[0036] The lens of surveillance camera 12 is pointed towards the blocked area to collect image information in real time;

[0037] The rotating component 2 is used to drive the rotating bevel gear 22 to rotate via the rotating motor 21. The power is transmitted through the linkage bevel gear 232 and the linkage shaft 231 to drive the support column 3 to rotate, thereby adjusting the horizontal angle of the main and auxiliary levers and flexibly adjusting the road closure range. The monitoring camera 12 on the top of the base 1 can monitor the dynamics of vehicles and pedestrians in the road closure area in real time. The reflective stickers on the surface of the main and auxiliary levers reflect light under illumination, enhancing the warning effect and improving overall safety.

[0038] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0039] The working principle is as follows:

[0040] Fix the base 1 in the designated position, install the main stop rod 7 on the connecting seat 5 by connecting bolt 6, insert the assembly block 91 at one end of the auxiliary stop rod 10 into the assembly groove 8 of the main stop rod 7, and screw in the assembly bolt 92 to complete the fixing of multiple auxiliary stop rods 10.

[0041] When the height of the road closure needs to be adjusted, the lifting motor 41 is started through the external controller or the control panel on the surface of the base 1. The lifting motor 41 drives the lifting screw 42 to rotate, and the cross plate 43 moves up and down along the lifting screw 42 and slides along the lifting groove 11 at the same time, driving the connecting seat 5 and the main and auxiliary stops to move up and down synchronously until the required height is reached.

[0042] When it is necessary to adjust the sealing angle, start the rotary motor 21. The rotary motor 21 drives the rotary bevel gear 22 to rotate, which in turn drives the linkage shaft 231 and the support column 3 to rotate through the meshing linkage bevel gear 232, thereby adjusting the horizontal angle of the main and auxiliary stops.

[0043] The surveillance camera 12 monitors the road closure area in real time. The reflective stickers reflect light when illuminated, alerting vehicles and pedestrians to take precautions.
