Description
Technical Field
[0001] This invention belongs to the technical field of engineering warning lights, and in particular relates to a warning light for forklifts used in engineering vehicles. Background Technology
[0002] The core function of forklift warning lights for construction vehicles is to provide proactive early warning and prevent accidents. Through visual signals, it establishes an efficient and timely communication channel between the construction vehicle and other road users, pedestrians, and workers in the surrounding environment. Construction vehicles are usually large and slow-moving, or when performing operations, their presence and behavior can be potential obstacles or hazards to other fast-moving vehicles. Flashing warning lights can attract attention from a distance and inform vehicles behind or oncoming in advance. In low visibility conditions, high-brightness, high-frequency flashing lights can effectively mark the outline and precise position of the vehicle, preventing rear-end collisions or crashes.
[0003] Common forklift warning lights are fixedly mounted on construction vehicles, using high-frequency, high-brightness flashing lights for warning purposes. However, in actual use, because the warning lights are fixed in position, repair and replacement are inconvenient when they are damaged or malfunctioning. Furthermore, the fixed position makes adjustment difficult, resulting in poor flexibility in practical use. The limited installation location also restricts their ability to provide warnings in different directions. Therefore, we provide a forklift warning light specifically for construction vehicles to solve the aforementioned technical problems. Summary of the Invention
[0004] The purpose of this invention is to provide a warning light for forklifts used in engineering vehicles. Through the specific structural design of the limit guide component, the warning support component, and the control drive component, the problems in the above-mentioned technical background are solved.
[0005] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution: The present invention is a warning light for forklifts used in engineering vehicles, comprising two limiting guide components symmetrically and fixedly connected to the forklift. Each limiting guide component includes a rotatably configured limiting control ring and a horizontally movable trapezoidal limiting block. A warning support component is slidably configured between the two limiting guide components. The warning support component engages with the two trapezoidal limiting blocks. The warning support component includes a control support frame that can rotate back and forth. A deflection support frame that can rotate left and right is rotatably configured on the surface of the control support frame. An adjustment drive component is fixedly connected to the upper surface of the warning support component. The adjustment drive component includes a horizontally movable adjustment transmission block. A drive bevel gear is rotatably connected to one side of the adjustment transmission block.
[0006] The present invention is further configured such that the limiting guide assembly includes a guide rail symmetrically fixedly connected to the surface of the forklift, a limiting support plate is slidably disposed inside the guide rail, a limiting reset spring is fixedly connected between the limiting support plate and the bottom of the guide rail, and the limiting support plate is located below the corresponding trapezoidal limiting block.
[0007] The invention is further configured such that: a guide slide rod is fixedly connected to one side of the trapezoidal limiting block; the guide slide rod slides through the corresponding guide rail; a transverse return spring is fixedly connected between the trapezoidal limiting block and the inner wall of the corresponding guide rail; the transverse return spring is sleeved on the outside of the guide slide rod; the limiting adjustment ring is rotatably connected to the corresponding guide rail; two driving connecting rods are symmetrically fixedly connected to the circumferential side of the limiting adjustment ring; two limiting adjustment ports are symmetrically opened on the circumferential side of the limiting adjustment ring; the limiting adjustment ports are inclined sliding surface structures relative to the two inner side walls; a transmission support rod is fixedly connected to the circumferential side of the guide slide rod; the transmission support rod slides in conjunction with the limiting adjustment port.
[0008] The invention is further configured such that the warning support assembly includes a warning support platform, the warning support platform has a limiting extension plate fixedly connected to its two opposite sides, the limiting extension plate is slidably engaged with the corresponding guide rail, two support plates are symmetrically fixedly connected to the upper surface of the warning support platform, the control support frame is rotatably connected to the two support plates, and a first bevel gear is rotatably connected to one side of the control support frame.
[0009] The invention is further configured such that: a support ear plate is fixedly connected to the upper surface of the warning support platform; a drive screw is rotatably connected to one side of the support ear plate; a second bevel gear is fixedly connected to one end of the drive screw, which passes through the two support plates and the first bevel gear; both the first and second bevel gears mesh with the drive bevel gear; a transmission internal threaded tube is threaded onto the circumferential side of the drive screw; several arc-shaped racks are fixedly connected to the circumferential side of the transmission internal threaded tube; a transmission slide rail is fixedly connected to the upper surface of the warning support platform; a transmission slider is slidably disposed inside the transmission slide rail; a support column is fixedly connected between the transmission internal threaded tube and the transmission slider; a deflection transmission gear is rotatably connected between the two inner sidewalls of the deflection support frame; the deflection transmission gear is adapted to the arc-shaped racks; and a warning support seat is fixedly connected to the upper surface of the deflection support frame; a warning light is installed on the upper surface of the warning support seat.
[0010] The present invention is further configured such that the control drive assembly includes a drive support frame fixedly connected to the upper surface of the warning support platform, the control transmission block and the drive support frame are slidably engaged, electromagnets are fixedly connected to the two inner side walls of the drive support frame, and magnets are fixedly connected to the two sides of the control transmission block; a control reset spring is fixedly connected between the control transmission block and the drive support frame, a guide slide is provided on one side of the drive support frame, and an extension support is fixedly connected to one side of the control transmission block and slidably engaged with the guide slide.
[0011] The present invention has the following beneficial effects: 1. By setting a limiting guide component, the limiting extension plate slides downward along the guide rail. When the limiting extension plate contacts the trapezoidal limiting block, the trapezoidal limiting block moves horizontally until the limiting extension plate disengages from the trapezoidal limiting block. The trapezoidal limiting block moves horizontally and limits the position of the limiting extension plate. By rotating the limiting adjustment ring, under the sliding cooperation between the limiting adjustment port and the transmission support rod, the trapezoidal limiting block moves horizontally, and the limiting extension plate loses its restriction. This enables the installation and disassembly of the warning device, facilitates replacement and maintenance operations, and improves the flexibility of the equipment.
[0012] 2. This invention, by setting up a warning support assembly, allows the first bevel gear to rotate, driving the adjustment support frame to rotate back and forth. Under the connection of the deflection support frame, the warning light rotates synchronously, allowing for front-to-back angle deflection adjustment. The second bevel gear is controlled to rotate, driving the drive screw to rotate. Under the threaded engagement of the drive screw and the internal threaded transmission tube, the internal threaded transmission tube drives the arc-shaped rack to move horizontally, thereby driving the deflection transmission gear to rotate, which in turn drives the deflection support frame to rotate, causing the warning light to rotate synchronously. This achieves horizontal, front-to-back, left-to-right angle deflection adjustment of the warning light, meeting the warning needs of different positions and improving the application scenarios of the equipment.
[0013] 3. This invention, by setting up a warning support component and a control drive component, controls the magnetic attraction between the electromagnet and the magnet, drives the control transmission block to slide along the inside of the drive support frame, drives the drive bevel gear to move horizontally synchronously, and thus makes the drive bevel gear mesh with the first bevel gear and the second bevel gear respectively, thereby realizing the control of different deflection angles and meeting the drive requirements of different deflection adjustments.

Detailed Implementation
[0023] 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.
[0024] For a specific implementation example, please refer to Implementation Example 1. Figure 1-7The present invention is a warning light for a forklift used in engineering vehicles, comprising two limiting guide components 1 symmetrically and fixedly connected to the forklift. Specifically, the limiting guide component 1 includes a rotatable limiting control ring 101 and a trapezoidal limiting block 102 that can move horizontally, and a warning support component 2 is slidably disposed between the two limiting guide components 1.
[0025] Furthermore, the warning support component 2 engages with the two trapezoidal limit blocks 102. The warning support component 2 includes an adjustable support frame 201 that can rotate back and forth. A deflection support frame 202 that can rotate left and right is rotatably provided on the surface of the adjustable support frame 201. An adjustable drive component 3 is fixedly connected to the upper surface of the warning support component 2. The adjustable drive component 3 includes an adjustable transmission block 301 that can move horizontally. A drive bevel gear 302 is rotatably connected to one side of the adjustable transmission block 301.
[0026] The operation process of this embodiment is as follows: The warning support component 2 slides downward between the two limiting guide components 1. The position of the warning support component 2 is limited by the two trapezoidal limiting blocks 102. The control transmission block 301 moves horizontally to the corresponding position, drives the bevel gear 302 to rotate, and the control support frame 201 rotates to drive the deflection support frame 202 to adjust the angle in the front and back directions to adjust the deflection of the warning device in the front and back directions. The control transmission block 301 moves horizontally in the opposite direction to the corresponding position, drives the bevel gear 302 to rotate, and drives the deflection support frame 202 to rotate independently to adjust in the left and right directions to adjust the deflection of the warning device in the front and back directions. When it is necessary to disassemble, replace or repair the warning support component 2, the limit control ring 101 is rotated to drive the trapezoidal limiting block 102 to move horizontally. The trapezoidal limiting block 102 removes the position limitation of the warning support component 2, making it convenient to remove the warning support component 2.
[0027] For a specific embodiment two, please refer to Figure 1-7 Based on the specific embodiment 1, specifically, the limiting guide component 1 also includes a guide slide rail 103 symmetrically fixedly connected to the surface of the forklift. A limiting support plate 104 is slidably arranged inside the guide slide rail 103. A limiting reset spring 105 is fixedly connected between the limiting support plate 104 and the bottom of the guide slide rail 103, and the limiting support plate 104 is located below the corresponding trapezoidal limiting block 102.
[0028] Furthermore, a guide slide rod 106 is fixedly connected to one side of the trapezoidal limiting block 102. The guide slide rod 106 slides through the corresponding guide slide rail 103. A transverse return spring 107 is fixedly connected between the trapezoidal limiting block 102 and the inner wall of the corresponding guide slide rail 103. The transverse return spring 107 is sleeved on the outside of the guide slide rod 106. The limiting control ring 101 is rotatably connected to the corresponding guide slide rail 103. Two drive linkages are symmetrically fixedly connected to the periphery of the limiting control ring 101. Two limiting control ports 108 are symmetrically opened on the periphery of the limiting control ring 101. The limiting control ports 108 are inclined sliding surface structures relative to the two inner side walls. A transmission support rod 109 is fixedly connected to the periphery of the guide slide rod 106. The transmission support rod 109 slides with the limiting control port 108. In the initial state, the transmission support rod 109 is located inside the corresponding limiting control port 108 and is in contact with the inner wall of the limiting control port 108.
[0029] Furthermore, the warning support assembly 2 also includes a warning support platform 203. The warning support platform 203 is fixedly connected to two opposite sides by a limiting extension plate 204. The limiting extension plate 204 is slidably engaged with the corresponding guide rail 103. Two support plates are symmetrically fixedly connected to the upper surface of the warning support platform 203. The control support frame 201 is rotatably connected to the two support plates, and a first bevel gear 205 is rotatably connected to one side of the control support frame 201.
[0030] Furthermore, a support ear plate is fixedly connected to the upper surface of the warning support platform 203. A drive screw 206 is rotatably connected to one side of the support ear plate. The drive screw 206 passes through the two support plates and is fixedly connected to a second bevel gear 207 at one end of the first bevel gear 205. Both the first bevel gear 205 and the second bevel gear 207 mesh with the drive bevel gear 302. In the initial state, the drive bevel gear 302 meshes with the first bevel gear 205. A transmission internal thread tube 208 is threaded onto the circumferential side of the drive screw 206. Several arc-shaped racks 209 are fixedly connected to the side of the 08. A transmission slide rail 210 is fixedly connected to the upper surface of the warning support platform 203. A transmission slider is slidably arranged inside the transmission slide rail 210. A support column is fixedly connected between the transmission internal thread tube 208 and the transmission slider. A deflection transmission gear 211 is rotatably connected between the deflection support frame 202 and the two inner side walls. The deflection transmission gear 211 is adapted to the arc-shaped racks 209. A warning support seat 212 is fixedly connected to the upper surface of the deflection support frame 202. A warning light 213 is installed on the upper surface of the warning support seat 212.
[0031] The operation process of this embodiment is as follows: The limiting extension plate 204 moves downward along the corresponding guide slide rail 103. After the limiting extension plate 204 contacts the limiting support plate 104, as the limiting extension plate 204 continues to move downward, it drives the limiting support plate 104 to slide downward along the guide slide rail 103. The limiting return spring 105 is gradually compressed. When the limiting support plate 104 contacts the trapezoidal limiting block 102, as the limiting support plate 104 moves downward, the trapezoidal limiting block 102 is squeezed and moves horizontally. The guide slide rod 106 moves horizontally at the same time, and the transverse return spring 107 is compressed until the limiting extension plate 204 disengages from the trapezoidal limiting block 102. The trapezoidal limiting block 102 loses its restriction. Under the elastic recovery action of the transverse return spring 107, the trapezoidal limiting block 102 limits the position of the limiting extension plate 204, thereby realizing the position limitation of the warning support component 2.
[0032] When it is necessary to disassemble and replace the warning support assembly 2, the limit adjustment ring 101 is rotated by the drive linkage. With the sliding cooperation between the limit adjustment port 108 and the transmission support rod 109, the external force applied to the transmission support rod 109 by the limit adjustment port 108 causes the transmission support rod 109 to move horizontally, which drives the guide slide rod 106 to move horizontally at the same time. The transverse return spring 107 is compressed, and the trapezoidal limit block 102 moves horizontally. The restriction effect of the trapezoidal limit block 102 on the limit extension plate 204 disappears. Under the elastic recovery action of the limit return spring 105, the limit extension plate 204 slides upward along the guide slide rail 103, and the warning support assembly 2 moves upward at the same time until the warning support assembly 2 is disassembled from the two guide slide rails 103, thereby realizing the disassembly operation of the warning support assembly 2.
[0033] For a specific embodiment three, please refer to Figure 1-7 Based on specific embodiments one and two, specifically, the control drive component 3 also includes a drive support frame 303 fixedly connected to the upper surface of the warning support platform 203, the control transmission block 301 and the drive support frame 303 are slidably engaged, electromagnets are fixedly connected to the two inner side walls of the drive support frame 303, and magnets are fixedly connected to the two sides of the control transmission block 301.
[0034] Furthermore, a regulating reset spring 304 is fixedly connected between the regulating transmission block 301 and the drive support frame 303. A guide slide is provided on one side of the drive support frame 303. An extension support that slides with the guide slide is fixedly connected to one side of the regulating transmission block 301. A drive motor is fixedly installed on one side of the extension support. The output shaft of the drive motor is fixedly connected to the drive bevel gear 302.
[0035] The operation process of this embodiment is as follows: When the warning light 213 needs to be adjusted, the drive motor is started, which drives the drive bevel gear 302 to rotate. Under the meshing action of the drive bevel gear 302 and the first bevel gear 205, the first bevel gear 205 rotates, which in turn drives the adjustment support frame 201 to rotate. By rotating the adjustment support frame 201 back and forth, the deflection support frame 202 and the warning light 213 rotate synchronously in the back and forth direction, thereby adjusting the tilt angle of the warning light 213. The external power supply of the electromagnet near the first bevel gear 205 is disconnected, and the external power supply of the electromagnet away from the first bevel gear 205 is connected. Under the magnetic attraction of the electromagnet and the magnet, the adjustment transmission block 301 slides horizontally along the inside of the drive support frame 303, and the meshing action between the drive bevel gear 302 and the first bevel gear 205 disappears. When the corresponding electromagnet and the magnet are in contact with each other, the drive bevel gear 302 meshes with the second bevel gear 207. When the drive motor is activated, it drives the drive bevel gear 302 to rotate. Under the meshing action of the drive bevel gear 302 and the second bevel gear 207, the second bevel gear 207 rotates, which in turn drives the drive screw 206 to rotate. Under the threaded engagement of the drive screw 206 and the transmission internal thread tube 208, and the sliding engagement of the transmission slider and the transmission slide rail 210, the transmission internal thread tube 208 moves along the circumferential side of the drive screw 206, the transmission slider slides along the inside of the transmission slide rail 210, and the arc rack 209 moves synchronously. Under the engagement of the arc rack 209 and the deflection transmission gear 211, the deflection transmission gear 211 rotates, which in turn drives the deflection support frame 202 to rotate independently. In this way, the deflection support frame 202 drives the warning light 213 to deflect in the front and rear directions. By adjusting the rotation of the support frame 201 and the deflection support frame 202, the angle of the warning light 213 can be adjusted at any angle to meet different usage needs.
