Description

Technical Field

[0001] This utility model relates to the field of lighting equipment technology, specifically an auxiliary lighting structure for excavators. Background Technology

[0002] Excavators, as important engineering machinery, are widely used in road construction, mining, building construction, and emergency rescue operations. Traditional excavators usually only have a few fixed lights installed on the top of the cab or at the base of the boom. When the excavator performs specific actions, such as raising the boom or extending the stick for high-level or deep digging operations, its own working device will completely block the lights, creating a large shadow blind spot in the work area, which seriously threatens operational safety and work accuracy.

[0003] Patent document CN220397378U discloses a lighting device for a wheeled excavator, including a base plate and a lamp assembly. Two placement blocks are fixedly mounted on the base plate, symmetrically arranged on both sides. A rotating shaft is rotatably mounted on each of the two placement blocks. Two counterweights are fixedly mounted on each rotating shaft, respectively positioned at both ends of the rotating shaft. A placement platform is fixedly mounted on the rotating shaft, and the lamp assembly is fixedly mounted on the placement platform. This invention has the advantage of improving lighting performance.

[0004] However, existing technologies still have shortcomings: the structural design is too simple, and the dust generated during excavation operations can easily adhere to the lighting bulbs, thus affecting the lighting effect of the lighting device on the excavation site.

[0005] Chinese patent discloses a lighting device for a wheeled excavator (authorization announcement number CN222669923U). This patented technology uses a cleaning structure to drive a rotating shaft three via a second motor. The rotating shaft three drives an arc-shaped scraper to rotate outside the lamp cover, allowing the soft brush on the inner side of the arc-shaped scraper to scrape and clean the outer surface of the lamp cover, removing dust adhering to the lamp cover surface, thereby improving the lighting effect of the lamp at the excavation site.

[0006] However, it has certain drawbacks: although a cleaning structure is set up to drive the arc-shaped scraper to rotate via a motor, it relies on a single arc-shaped scraper for continuous cleaning. In actual long-term operation, the soft brush on the inner side of the arc-shaped scraper will accumulate dust, wear down, or even harden due to continuous scraping, causing its cleaning efficiency to drop rapidly. It cannot effectively remove dust from the surface of the lampshade, resulting in a decrease in lighting brightness. Operators have to frequently interrupt the operation to clean or replace the lampshade in order to restore the lighting effect, which seriously affects the continuous working efficiency and safety of the excavator in dusty environments. Utility Model Content

[0007] The purpose of this invention is to provide an auxiliary lighting structure for excavators to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] An auxiliary lighting structure for an excavator includes a lighting housing, a lamp cover rotatably connected through the front surface of the lighting housing, and a rotating mechanism jointly provided on one end of the lamp cover located inside the lighting housing and the upper surface of the lighting housing.

[0010] A support ring is fixed to the front surface of the lighting housing on the outside of the lampshade, and multiple wiping components are evenly arranged inside the support ring;

[0011] A fixing plate is fixed to the front surface of the lighting lamp housing, located outside the support ring and directly opposite the wiping component. A telescopic cylinder is fixed to the side surface of the fixing plate away from the wiping component. A push plate is fixed to the telescopic end of the telescopic cylinder. A push rod is fixed to the side surface of the push plate near the telescopic cylinder and located outside the telescopic cylinder.

[0012] As a further embodiment of this utility model: the rotating mechanism includes a support block, a motor is fixedly connected to the rear surface of the support block, a gear is fixedly connected to the output end of the motor, and a gear is meshed with the lower side of the gear.

[0013] As a further embodiment of this utility model: the support block is fixed to the upper surface of the lighting housing, the first gear moves through the upper surface of the lighting housing, the second gear is located inside the lighting housing, and the second gear is fixedly sleeved on the outside of the lampshade.

[0014] As a further embodiment of this utility model: the wiping component includes a rod, an arc-shaped plate is fixedly connected to one end of the rod near the lampshade, a wiping plate is fixedly connected to one side surface of the arc-shaped plate near the lampshade, a baffle is fixedly connected to one end of the rod away from the lampshade, a stop bar is fixedly connected to one side surface of the baffle near the rod and located outside the rod, and a spring is movably sleeved on the outside of the stop bar.

[0015] As a further embodiment of this utility model: the insert rod movably passes through the support ring, the arc-shaped plate is located inside the support ring, the wiping plate is directly opposite the lampshade, the baffle is located outside the support ring, the stop rod movably passes through the support ring, and the spring is located between the support ring and the baffle.

[0016] As a further improvement of this utility model: the push plate is directly opposite the baffle, and the push rod movably passes through the fixed plate.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] This invention features a motor-driven rotatable lampshade and wiping components controlled by multiple independent telescopic cylinders. This allows operators to automatically clean the lampshade from the cab without leaving the machine. During long, continuous operations, if the cleaning effect of one wiping plate decreases due to repeated use, it can be quickly switched to another clean wiping plate to continue working. This effectively avoids work interruptions caused by stopping to change wiping plates midway, significantly improving the excavator's continuous operating efficiency and lighting guarantee under harsh conditions. All wiping plates can be disassembled and maintained uniformly after the entire work is completed, greatly simplifying the maintenance process. Attached Figure Description

[0025] Please see Figure 1 In this embodiment of the present invention, an auxiliary lighting structure for an excavator includes a lighting lamp housing 1;

[0026] The lighting housing 1 can be bolted to the boom or stick of the excavator;

[0027] The lighting housing 1 has an internal cavity for mounting LED light panels and other light sources. The light source is electrically connected to the power supply and control system in the excavator's operating room via an oil-resistant and wear-resistant sheathed cable. The cable route should be fixed along the working mechanism to avoid interference with moving parts.

[0028] The lampshade 2 is rotatably connected to the front surface of the lighting housing 1, and the two can be rotatably connected by a bearing; the bearing includes a bearing with a sealing ring and an independent radial oil seal, so as to ensure smooth rotation of the lampshade while forming an effective dynamic seal at the gap between the lampshade and the lighting housing 1, preventing mud, water and dust from entering the interior of the housing;

[0029] The lampshade 2 is used for light transmission and to prevent external dust from entering the interior of the lighting housing 1;

[0030] The lampshade 2 is preferably made of polycarbonate, which has high light transmittance, impact resistance and weather resistance.

[0031] exist Figures 1-3 In the middle: The lampshade 2 is located at one end inside the lighting housing 1 and the upper surface of the lighting housing 1 are jointly provided with a rotating mechanism 3. The rotating mechanism 3 includes a support block 4, which is fixed to the upper surface of the lighting housing 1. A motor 5 is fixed to the rear surface of the support block 4. A gear 6 is fixed to the output end of the motor 5. The gear 6 moves through the upper surface of the lighting housing 1.

[0032] Similarly, motor 5 is also electrically connected to the power supply and control system in the excavator's operating room. The cable should be fixed along the working mechanism to avoid interference with moving parts.

[0033] The upper surface of the lighting housing 1 is located outside the support block 4, motor 5 and gear 6. A protective cover can be installed with bolts. The surface of the protective cover has through holes with a filter screen for heat dissipation of motor 5.

[0034] Gear 6 is meshed with gear 7 on its lower side. Gear 7 is located inside the lamp housing 1 and is fixedly sleeved on the outside of the lamp cover 2.

[0035] The meshing of gear 6 and gear 7 is used to drive the lampshade 2 to rotate.

[0036] exist Figure 1 and Figure 4 In the middle: A support ring 8 is fixedly connected to the front surface of the lighting housing 1 on the outside of the lamp cover 2, and multiple wiping parts 9 are evenly arranged inside the support ring 8;

[0037] The number of wiping parts 9 is preferably three, to avoid excessive light blockage caused by too many parts;

[0038] Wiping component 9 includes a plug 10, which movably passes through the support ring 8, and an arc-shaped plate 11 is fixedly connected to one end of the plug 10 near the lamp cover 2;

[0039] The insertion rod 10 and the arc plate 11 can be fixed together by bolts, which allows the arc plate 11 to be disassembled.

[0040] The arc-shaped plate 11 is located inside the support ring 8. A wiping plate 12 is fixed to the surface of the arc-shaped plate 11 near the lamp cover 2. The wiping plate 12 is directly opposite the lamp cover 2.

[0041] The wiping plate 12 is used to wipe and clean the surface of the lampshade 2 to prevent dust from adhering and affecting the light effect;

[0042] The wiping plate 12 is preferably made of fiber cloth, silicone scraper, or soft felt; the wiping plate 12 and the arc plate 11 can be fixed together by industrial glue or bolts;

[0043] A baffle 13 is fixedly connected to the end of the insert rod 10 away from the lamp cover 2. The baffle 13 is located outside the support ring 8. A stop rod 14 is fixedly connected to the side surface of the baffle 13 near the insert rod 10 and outside the insert rod 10. The stop rod 14 moves through the support ring 8. A spring 15 is movably sleeved on the outside of the stop rod 14. The spring 15 is located between the support ring 8 and the baffle 13.

[0044] The spring 15 is initially in its natural state, that is, it is not compressed or stretched, and at this time the wiping plate 12 does not contact the lamp cover 2;

[0045] The spring 15 is preferably made of stainless steel, such as 304 or 316 stainless steel;

[0046] By removing the arc plate 11, the insert rod 10, baffle 13, and stop rod 14 can be pulled out, allowing the spring 15 to be replaced and maintained.

[0047] exist Figure 1 , Figure 4 and Figure 5 In the middle: A fixing plate 16 is fixedly connected to the front surface of the lighting housing 1 at the position outside the support ring 8 and directly opposite the wiping component 9. A telescopic cylinder 17 is fixedly connected to the side surface of the fixing plate 16 away from the wiping component 9.

[0048] The telescopic cylinder 17 is preferably an electric cylinder, and its circuit is also connected to the control system of the excavator's operating cab;

[0049] A protective cover can be installed on the side surface of the fixing plate 16 away from the wiping component 9 and located outside the telescopic cylinder 17 to protect the telescopic cylinder 17;

[0050] The telescopic cylinder 17 has a push plate 18 fixedly connected to its telescopic end, and the push plate 18 is directly opposite the baffle 13.

[0051] The telescopic cylinder 17 is initially in the retracted state. At this time, the push plate 18 does not contact the baffle 13. After the telescopic cylinder 17 extends, the push plate 18 contacts and pushes the baffle 13, causing the arc plate 11 to move towards the lampshade 2 until the wiping plate 12 is in contact with the lampshade 2.

[0052] A push rod 19 is fixedly connected to the side surface of the push plate 18 near the telescopic cylinder 17 and located outside the telescopic cylinder 17. The push rod 19 moves through the fixed plate 16.

[0053] The push rod 19 serves to assist in guidance and enhance the stability of the push plate 18 during movement.

[0054] The working principle of this utility model is as follows: The operator turns on the power of the lighting lamp in the excavator's operating room, so that the light source inside the lighting lamp housing 1 starts working. When the surface of the lamp cover 2 is covered with dust, mud, and other dirt due to the working environment, resulting in a decrease in lighting effect, the operator can manually start the cleaning process. First, the operator controls one of the telescopic cylinders 17 to extend from the operating room. The telescopic cylinder 17 pushes the push plate 18 forward, thereby pressing the corresponding baffle 13, compressing the spring 15, and forcing the insert rod 10 to drive the arc plate 11 and the wiping plate 12 fixed thereon to move towards the lamp cover 2 until the wiping plate 12 is tightly attached to the outer surface of the lamp cover 2. Then, the operator starts the motor 5. The motor 5 drives the lamp cover 2 to rotate continuously and slowly on the lighting lamp housing 1 through the meshing of gear 6 and gear 7. During this process, the stationary wiping plate... The wiping plate 12 can thoroughly scrape and clean the entire outer surface of the rotating lampshade 2, effectively removing accumulated dirt. After completing one or several cleaning cycles, the operator first turns off the motor 5, then controls the telescopic cylinder 17 to retract. Under the reset action of the spring 15, the wiping plate 12 disengages from the surface of the lampshade 2. If, during long-term operation, a certain wiping plate 12 accumulates too much dirt or becomes worn due to repeated use, resulting in unsatisfactory cleaning results, the operator does not need to stop the machine. Instead, the operator simply retracts the current telescopic cylinder 17 from the control room and turns on the switch of another telescopic cylinder 17, causing it to drive another set of clean or intact wiping plates 12 to adhere to the lampshade 2, thus continuing to perform effective cleaning tasks. This achieves online switching and continuous maintenance of the wiping components 9, ensuring the long-lasting and efficient operation of the lighting system under harsh conditions.
