Description

Technical Field

[0001] This utility model relates to the field of police light lifting technology, and in particular to a vehicle police light lifting mechanism and an engineering emergency vehicle. Background Technology

[0002] In the field of emergency rescue and engineering disaster relief, engineering rescue vehicles, as core equipment, undertake critical tasks such as road repair, power restoration, pipeline maintenance, and disaster relief. Their operational efficiency and safety directly affect the safety of life and property and the stable restoration of social order. As an important warning device for engineering rescue vehicles, warning lights must have sufficient height and visibility during operation to convey warning signals to surrounding vehicles and pedestrians, delineate safe working areas, and prevent secondary accidents. Therefore, the raising and lowering function of warning lights is one of the core factors affecting the warning effect and operational safety of rescue vehicles. Currently, the warning light raising and lowering devices used in engineering rescue vehicles are mainly divided into two categories: manual raising and lowering and electric raising. Manual raising and lowering devices rely on operators to manually adjust the height of the warning lights, which is not only cumbersome and time-consuming, but can also delay operations in emergency rescue scenarios. Furthermore, operators must operate from the top of the vehicle or in dangerous areas, posing safety hazards such as falls and collisions. While electric raising and lowering devices have improved automation, they generally suffer from complex structural designs, insufficient stability, and weak adaptability to harsh environments. For example, some electric lifting devices use a single screw drive or gear drive structure, which is prone to wear and jamming of transmission components after long-term high-frequency use, resulting in failure of the lifting action; another example is the use of a single lifting mechanism to lift the warning light, which occupies a high height, is difficult to lower the warning light to a lower position when retracting, and has low lifting efficiency. Utility Model Content

[0003] Based on the above, the purpose of this utility model is to provide a vehicle-mounted police light lifting mechanism and an engineering emergency vehicle, which has high lifting efficiency and occupies less height when retracted.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A vehicle warning light lifting mechanism, comprising:

[0006] Mounting base;

[0007] The support rail is vertically mounted on the mounting base;

[0008] A primary lifting track moves along the height direction and is connected to the supporting track;

[0009] A secondary lifting track, which moves along the height direction and is connected to the primary lifting track, is used to install warning lights;

[0010] A drive assembly is provided for driving the primary lifting rail to move up and down along the height direction on the support rail, and simultaneously driving the secondary lifting rail to move up and down synchronously along the height direction on the primary lifting rail.

[0011] As a preferred embodiment of a vehicle-mounted police light lifting mechanism, the drive assembly includes:

[0012] A driving component is disposed on the mounting base and drives the primary lifting rail. The driving component drives the primary lifting rail to move up and down along the height direction on the support rail.

[0013] The transmission component includes a transmission sprocket and a transmission chain. The transmission sprocket is mounted on the primary lifting track, and the transmission chain is wound around the transmission sprocket. One end of the transmission chain is connected to the support track, and the other end is connected to the secondary lifting track.

[0014] As a preferred embodiment of a vehicle-mounted police light lifting mechanism, the driving component is a hydraulic cylinder, with one end of the hydraulic cylinder connected to the mounting base and the other end connected to the primary lifting rail.

[0015] As a preferred embodiment of a vehicle-mounted police light lifting mechanism, it also includes a fixing frame, which is mounted on the mounting base, and the hydraulic cylinder is fixed on the fixing frame.

[0016] As a preferred embodiment of a vehicle-mounted police light lifting mechanism, the support rail includes two parallel and spaced support slide rails, the primary lifting rail includes two primary lifting slide rails and a crossbar connected between the two primary lifting slide rails, each primary lifting slide rail is slidably connected to one of the support slide rails, and one end of the hydraulic cylinder is connected to the crossbar.

[0017] As a preferred embodiment of a vehicle-mounted police light lifting mechanism, each of the supporting slide rails is provided with a first fixing plate, and one end of each of the transmission chains is detachably connected to one of the first fixing plates.

[0018] As a preferred embodiment of a vehicle-mounted police light lifting mechanism, the secondary lifting track includes two secondary lifting slide rails and a base rod located between the two secondary lifting slide rails. Each secondary lifting slide rail is slidably connected to one primary lifting slide rail. The position of the base rod in the height direction is always lower than the position of the transmission sprocket in the height direction. One end of the transmission chain is connected to the base rod.

[0019] As a preferred embodiment of a vehicle-mounted police light lifting mechanism, the base rod is provided with two second fixing plates, and one end of each transmission chain is detachably connected to one of the second fixing plates.

[0020] As a preferred embodiment of a vehicle-mounted police light lifting mechanism, the transmission component is provided in two parts. The two transmission sprockets are respectively rotatably mounted on one of the first-stage lifting slide rails. One end of each transmission chain is connected to a support slide rail, and the other end is connected to the base rod.

[0022] The beneficial effects of this utility model are as follows:

[0023] This utility model provides a vehicle siren light lifting mechanism. When the siren light needs to be raised for a warning purpose, a drive assembly drives the primary lifting rail to rise, simultaneously causing the secondary lifting rail to rise synchronously, thus raising the siren light. When the siren light needs to be lowered, the same drive assembly drives the primary lifting rail to descend, simultaneously causing the secondary lifting rail to descend synchronously, thus lowering the siren light. The hierarchical arrangement of the support rail, primary lifting rail, and secondary lifting rail allows the siren light to rise to a sufficiently high height for a clear warning effect, while also allowing it to descend to a sufficiently low position when retracted, avoiding excessive space and height occupation. Furthermore, the synchronous raising and lowering of the primary and secondary lifting rails through the drive assembly helps save power travel, improves lifting efficiency, and reduces lifting time.

It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

They are used solely for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.

[0034] This embodiment provides a vehicle warning light lifting mechanism, which is used on an engineering emergency vehicle to raise or lower the warning light 10 installed on it. The warning light 10 is raised to serve as a warning during engineering operations, and the warning light 10 is lowered when no engineering operations are being carried out to avoid affecting the overall height of the engineering emergency vehicle.

[0035] Specifically, the vehicle-mounted warning light lifting mechanism includes a mounting base 1, a support rail 2, a primary lifting rail 3, a secondary lifting rail 4, and a drive assembly 5. The mounting base 1 is used to install and fix the vehicle on an emergency rescue vehicle. The support rail 2 is vertically mounted on the mounting base 1. The primary lifting rail 3 is movable along the height direction and connected to the support rail 2, where the height direction refers to the direction perpendicular to the mounting surface of the mounting base 1 and the same as the length direction of the support rail 2. The secondary lifting rail 4 is movable along the height direction and connected to the primary lifting rail 3, and is used to mount the warning light 10. The drive assembly 5 is used to drive the primary lifting rail 3 to move and lift along the height direction on the support rail 2, while simultaneously driving the secondary lifting rail 4 to move and lift synchronously along the height direction on the primary lifting rail 3. When the warning light 10 needs to be raised for a warning purpose, the drive assembly 5 drives the primary lifting rail 3 to rise, while simultaneously driving the secondary lifting rail 4 to rise synchronously, thus raising the warning light 10. When the warning light 10 needs to be lowered, the drive assembly 5 similarly drives the primary lifting rail 3 to descend, while simultaneously driving the secondary lifting rail 4 to descend synchronously, thus lowering the warning light 10. The hierarchical arrangement of support rail 2, primary lifting rail 3, and secondary lifting rail 4 allows the warning light 10 to rise to a sufficiently high height for a clear warning effect, while also allowing it to descend to a sufficiently low position when retracted, avoiding excessive space and height occupation and thus preventing obstruction of emergency rescue vehicles passing through height-restricted sections. Furthermore, the drive component 5 enables the primary lifting rail 3 and secondary lifting rail 4 to rise and fall synchronously, which helps save power travel, improves lifting efficiency, and saves lifting time.

[0036] In this embodiment, the drive assembly 5 includes a drive component 51 and a transmission component 52. The drive component 51 is mounted on the mounting base 1 and drives the primary lifting rail 3. The drive component 51 drives the primary lifting rail 3 to move and lift along the support rail 2 in the height direction. The transmission component 52 includes a transmission sprocket 521 and a transmission chain 522. The transmission sprocket 521 is mounted on the primary lifting rail 3, and the transmission chain 522 is wound around the transmission sprocket 521, with one end connected to the support rail 2 and the other end connected to the secondary lifting rail 4. Power is provided by the drive component 51, causing the primary lifting track 3 to move up and down. When the primary lifting track 3 moves up, since one end of the transmission chain 522 is connected to the stationary support track 2, the transmission sprocket 521 rotates accordingly, and the transmission chain 522 moves around the transmission sprocket 522. The other end of the transmission chain 522 pulls the secondary lifting track 4 upward, causing the secondary lifting track 4 to rise synchronously, thus achieving the rapid rise of the warning light 10. When the primary lifting track 3 descends, the secondary lifting track 4 descends synchronously under the action of gravity, and the transmission chain 522 moves in the opposite direction around the transmission sprocket 521, thus achieving the rapid descent of the warning light 10.

[0037] Preferably, the driving component 51 is a hydraulic cylinder, with one end connected to the mounting base 1 and the other end connected to the primary lifting rail 3. The extension and retraction of the hydraulic cylinder raises and lowers the primary lifting rail 3, resulting in a structure with high strength, easy operation, simple structure, and convenient installation. The raising and lowering of both the primary and secondary lifting rails 3 and 4 can be achieved using only one hydraulic cylinder, saving on the hydraulic cylinder's driving stroke and power, as well as saving space. Of course, in other embodiments, the driving component 51 can also be other components, such as a pneumatic cylinder.

[0038] Preferably, the hydraulic cylinder is mounted on the mounting base 1 via a fixing bracket 8, that is, the fixing bracket 8 is set on the mounting base 1, and the outer cylinder of the hydraulic cylinder is fixed on the fixing bracket 8 to ensure the stability of the hydraulic cylinder during operation.

[0039] Furthermore, the support rail 2 includes two parallel and spaced support slide rails 21, and the primary lifting rail 3 includes two primary lifting slide rails 31 and a crossbar 32 connecting the two primary lifting slide rails 31. Each primary lifting slide rail 31 is slidably connected to one support slide rail 21, and one end of the hydraulic cylinder is connected to the crossbar 32. The pair of primary lifting slide rails 31 helps to improve the stability of the vehicle warning light lifting mechanism. The crossbar 32 provides an installation position for the connection of the hydraulic cylinder. When the hydraulic cylinder extends or retracts, it drives the crossbar 32 to rise or fall, thereby driving the two primary lifting slide rails 31 to rise or fall synchronously.

[0040] Preferably, each primary lifting slide rail 31 is slidably connected to a support slide rail 21 via a slider to improve the smoothness of sliding.

[0041] Specifically, the secondary lifting track 4 includes two secondary lifting slide rails 41 and a base rod 42 located between the two secondary lifting slide rails 41. Each secondary lifting slide rail 41 is slidably connected to a primary lifting slide rail 31. The base rod 42 is always lower in the height direction than the transmission sprocket 521. One end of the transmission chain 522 is connected to the base rod 42. The pair of secondary lifting slide rails 41 helps improve the stability of the vehicle warning light lifting mechanism and facilitates the installation of the warning light 10, ensuring the installation stability of the warning light 10. The base rod 42 is located at the bottom of the secondary lifting track 4, and one end of the transmission chain 522 is connected to the base rod 42. When the primary lifting track 3 and the secondary lifting track 4 rise to their highest point, the transmission chain 522 is always wound around the transmission sprocket 521 to prevent it from detaching from the transmission sprocket 521.

[0042] Preferably, each secondary lifting slide rail 41 is slidably connected to a primary lifting slide rail 31 via a slider to improve the smoothness of sliding.

[0043] In this embodiment, two transmission components 52 are provided. Two transmission sprockets 521 are respectively rotatably mounted on a primary lifting slide rail 31. One end of each transmission chain 522 is connected to a support slide rail 21, and the other end is connected to the base rod 42. The arrangement of two transmission components 52 ensures that when the primary lifting rail 3 moves up and down, driving the secondary lifting rail 4 to move up and down through the transmission components 52, the secondary lifting rail 4 experiences more uniform force, resulting in better lifting stability. The two secondary lifting slide rails 41 also exhibit high synchronicity in their movement, preventing asynchrony and jamming.

[0044] Specifically, each support slide rail 21 is provided with a first fixing plate 6, and one end of each transmission chain 522 is detachably connected to one of the first fixing plates 6. For example, one end of the transmission chain 522 is connected to a bolt, which is threaded to the first fixing plate 6 and threaded to a nut, facilitating disassembly and assembly, and facilitating adjustment of the tension of the transmission chain 522.

[0045] Specifically, two second fixing plates 7 are provided on the base rod 42, and one end of each transmission chain 522 is detachably connected to one of the second fixing plates 7. For example, the other end of the transmission chain 522 is connected to a bolt, which is threaded to the second fixing plate 7 and threaded to a nut, facilitating disassembly and assembly, as well as adjusting the tension of the transmission chain 522.

[0046] This embodiment also provides an engineering emergency rescue vehicle, which includes a vehicle body and a vehicle warning light lifting mechanism as described above, mounted on the vehicle body. By adopting the above-described vehicle warning light lifting mechanism, it is easy to raise the warning light 10 to a sufficient height and also to lower the warning light 10 to a sufficiently low position, with high lifting efficiency and good practicality.

Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, and substitutions can be made without departing from the scope of protection of the present invention.
