Description

Technical Field

[0001] This application belongs to the field of automotive parts technology, and more specifically, relates to a work light bracket and a wide-body mining dump truck equipped with such a work light bracket. Background Technology

[0002] Mining areas are typically located in remote areas with limited public lighting, and much of the work is carried out at night, in the early morning, or in dimly lit tunnels. Work lights provide drivers and maintenance personnel with basic visibility. Furthermore, mining areas generate extremely high levels of dust, and combined with adverse weather conditions such as rain, snow, and fog, visibility is extremely low. High-intensity work lights can penetrate a certain degree of dust to illuminate critical areas, ensuring efficient and rapid maintenance or emergency repairs.

[0003] Therefore, in mining operations, wide-body mining dump trucks typically need to be equipped with work lights to meet lighting requirements at night or in low-light conditions. Work lights are primarily used to illuminate critical parts of the vehicle, such as the tires, chassis, and surrounding work area, facilitating observation, inspection, and maintenance by the driver and maintenance personnel, thereby ensuring operational safety and efficiency.

[0004] Current work lights often use gear rotation or screw adjustment to adjust the beam angle and expand the illumination area. However, these two angle adjustment methods have obvious shortcomings in practical applications: gear rotation is complex, screw adjustment is inconvenient, and current work lights also have problems such as cumbersome fixing methods and damage when the work light touches an obstacle. Utility Model Content

[0005] The purpose of this application is to provide a work light bracket and a wide-body mining dump truck, which aims to solve the problem of inconvenient adjustment of the current work light illumination angle.

[0006] Firstly, to achieve the above objectives, the technical solution adopted in this application is: to provide a work light bracket, comprising: Mounting bracket, which can be mounted on the vehicle frame; A rotating frame is rotatably mounted on the mounting frame via a rotating shaft, and an angle adjustment and positioning structure is provided between the rotating frame and the mounting frame; both the mounting frame and the rotating frame are provided with through holes through which the rotating shaft passes; multiple indexing holes are evenly distributed on the concentric circle of one of the through holes, and positioning holes that are coaxial with any one of the indexing holes are provided around the other through hole; The angle adjustment positioning structure includes a quick-connect positioning pin passing through the positioning hole and any one of the indexing holes; and The work light is mounted on the rotating frame and can adjust the illumination angle as the rotating frame rotates, and is positioned by the quick-connect positioning pin.

[0007] The beneficial effects of the work light bracket provided in this application are as follows: Compared with the prior art, the mounting bracket of this application is fixedly mounted on the vehicle frame, the rotating bracket is rotatably mounted on the mounting bracket, and the work light is mounted on the rotating bracket. The work light's illumination angle can be adjusted by rotating the rotating bracket. Furthermore, the rotating bracket can be positioned by inserting a quick-connect positioning pin into the corresponding indexing hole, thereby positioning the work light. This rotating structure does not require complex gear engagement; a common shaft can be used to rotatably connect the rotating bracket and the mounting bracket. The quick-connect positioning pin can be quickly inserted into the corresponding indexing hole without the need for screws. The angle adjustment and subsequent positioning of the work light are simple and convenient, improving the work efficiency of maintenance personnel. In conjunction with the first aspect, in one possible implementation, the angle adjustment positioning structure further includes; A fixed outer casing is fitted over the positioning hole of the rotating frame or the mounting frame; The elastic element is elastically confined within the fixed housing; and The adjusting lever passes through the fixed housing and the elastic element, and is fixedly connected to the quick-connect positioning pin that passes through the positioning hole; When the adjusting lever is lifted upwards, the elastic element is compressed, causing the quick-connect positioning pin to disengage from the indexing hole to rotate the illumination angle of the work light. When the adjusting lever is released, the quick-connect positioning pin passes through the indexing hole on the coaxial axis, and the elastic element presses the quick-connect positioning pin to position the work light.

[0008] In the above technical solution, the fixed outer shell restricts the elastic element, and the elastic element elastically presses the quick-connect positioning pin, which can prevent the quick-connect positioning pin from coming out of the indexing hole, thus ensuring the reliability of the work light positioning.

[0009] In conjunction with the first aspect, in one possible implementation, the angle adjustment and positioning structure further includes a mounting plate fixed to the rotating frame or the mounting bracket, the fixed housing being fixed to the mounting plate, and the mounting plate having a pin hole through which the quick-connect positioning pin passes.

[0010] This design allows the angle adjustment positioning structure to be assembled as a whole before being fixed to the rotating frame or mounting frame. This is because the mounting plate has a limiting constraint effect on the quick-connect positioning pin. Without the mounting plate, the elastic element and quick-connect positioning pin lack restraint. When the positioning structure is removed, the elastic element is not restrained and will be stretched under the weight of the quick-connect positioning pin, or the end cap of the quick-connect positioning pin will come out of the fixed shell, which will make assembly inconvenient.

[0011] In conjunction with the first aspect, in one possible implementation, the quick-connect positioning pin is made of nylon or polyethylene.

[0012] The aforementioned technical solution involves replacing the material of the quick-connect positioning pin with a low-strength material, specifically nylon or polyethylene. The mounting bracket and rotating bracket are made of stainless steel or alloy steel, ensuring a secure connection to the vehicle frame and sufficient support for the work light. When the rotating bracket of the work light encounters an obstacle during vehicle movement, the impact force can disengage at the lower-strength quick-connect positioning pin, unlocking the rotating bracket. Under impact, the rotating bracket can then rotate, avoiding the obstacle and preventing damage. This also prevents the impact force from being transmitted to the vehicle frame due to the rigidity of the rotating bracket, thus avoiding damage to the frame. Therefore, this application uses a low-strength material for the quick-connect positioning pin, creating a weak point. When the rotating bracket is subjected to force, this weak point first collapses and absorbs energy, causing damage. This allows the unlocked rotating bracket to rotate and avoid the obstacle, protecting the work light, rotating bracket, mounting bracket, and vehicle frame from damage.

[0013] In conjunction with the first aspect, in one possible implementation, the lower end of the adjusting lever is threadedly connected to the quick-connect locating pin. This threaded connection facilitates the removal of the adjusting lever from the quick-connect locating pin after damage, eliminating the need for replacement, reducing maintenance costs, and simplifying assembly.

[0014] In conjunction with the first aspect, in one possible implementation, the upper end of the adjusting lever is provided with a handwheel for easy lifting. By providing a handwheel at the end of the adjusting lever, the surface area of ​​the upper end of the adjusting lever is increased, thereby facilitating the operation of lifting the adjusting lever by maintenance personnel.

[0015] In conjunction with the first aspect, in one possible implementation, the mounting bracket has a first mounting portion and a second mounting portion connected to the rotating frame, and a third mounting portion connected to the vehicle frame; both the first mounting portion and the second mounting portion are provided with the through hole; The rotating frame has a U-shaped frame structure and has a first connecting end and a second connecting end that connect the first mounting part and the second mounting part respectively. The first connecting end and the second connecting end are provided with the through hole. The indexing hole is provided on the third mounting part; the positioning hole is provided on the second connecting end; The rotating frame and the mounting frame are connected to form a hollow cavity, and the work light is installed inside the hollow cavity.

[0016] In the above technical solution, the rotating frame and the mounting frame are connected to form a frame structure. The enclosed hollow cavity not only protects the work light, but the rotating frame and mounting frame used in this application have a simple structure. The mounting frame has three mounting parts, and the rotating frame only needs two connecting ends, which are connected together by two rotating shafts. The entire bracket structure is simple, easy to assemble, and the illumination angle adjustment is also simple and convenient. This not only reduces manufacturing costs but also improves maintenance efficiency.

[0017] In conjunction with the first aspect, in one possible implementation, the rotating frame is constructed from bent sheet metal to form the first connecting end and the second connecting end arranged in parallel. The mounting bracket includes a first support plate and a second support plate vertically connected to the first support plate. The first support plate has a first mounting portion and a third mounting portion formed at both ends. The second support plate has a second mounting portion formed by bending its end.

[0018] In the above technical solution, the rotating frame can be made by bending stainless steel plate to form a U-shaped frame with one end open. The second support plate of the mounting frame can seal this opening, so that the rotating frame and the mounting frame form a closed hollow cavity, which provides reliable protection for the work light and avoids the risk of the work light being directly hit. This bracket structure is simple and easy to install on the vehicle frame. Generally, mounting holes are provided on the third mounting part of the mounting frame.

[0019] In conjunction with the first aspect, in one possible implementation, the first connecting end and the second connecting end of the rotating frame are positioned between the first mounting portion and the second mounting portion. Since the rotating frame is an open U-shaped frame, the bends exhibit a certain degree of elastic deformation, and the opening is prone to deformation and expansion. Confining these two connecting ends between the two mounting portions reduces the axial constraint force on the rotating shaft, thereby improving the robustness of the connection between the rotating frame and the mounting frame.

[0020] Secondly, this application also provides a wide-body mining dump truck, on which the aforementioned work light bracket is mounted.

[0021] Because this wide-body mining dump truck uses this type of work light bracket, the work light can be quickly rotated and adjusted, saving maintenance time. The frame-type rotating bracket protects the work light and reduces damage. The low-strength quick-connect positioning pin breaks when it touches an obstacle, protecting the work light, work light bracket, and chassis. Moreover, replacing the quick-connect positioning pin separately after damage reduces maintenance costs, thereby improving the overall usability of the vehicle. Attached Figure Description

[0030] Please refer to the following: Figures 1 to 4 The work light bracket provided in this application will now be described. The work light bracket includes a mounting frame 3, a rotating frame 2, and a work light 1. The mounting frame 3 can be mounted on a vehicle frame. The rotating frame 2 is rotatably mounted on the mounting frame 3 via a rotating shaft 4, and an angle adjustment and positioning structure 5 is provided between the rotating frame 2 and the mounting frame 3. Both the mounting frame 3 and the rotating frame 2 have through holes 37 through which the rotating shaft 4 passes. Multiple indexing holes 38 are evenly distributed on the concentric circle of one of the through holes 37, and a positioning hole coaxial with any one of the indexing holes 38 is provided around the other through hole 37. The angle adjustment and positioning structure 5 includes a quick-connect positioning pin 505 passing through the positioning hole and any one of the indexing holes 38. The work light 1 is mounted on the rotating frame 2, and its illumination angle can be adjusted by rotating with the rotating frame 2, and it is positioned by the quick-connect positioning pin 505.

[0031] Compared with the prior art, the work light bracket provided in this application has a different design. The mounting bracket 3 is fixedly mounted on the vehicle frame, the rotating bracket 2 is rotatably mounted on the mounting bracket 3, and the work light 1 is mounted on the rotating bracket 2. The rotation of the rotating bracket 2 allows for adjustment of the illumination angle of the work light 1. Furthermore, by inserting the quick-connect positioning pin 505 into the corresponding indexing hole 38, the rotating bracket 2 can be positioned, thereby positioning the work light 1. This rotating structure does not require complex gear engagement; a common rotating shaft 4 can be used to rotatably connect the rotating bracket 2 and the mounting bracket 3. The quick-connect positioning pin 505 can be quickly inserted into the corresponding indexing hole 38 without the need for screws. The angle adjustment and positioning of the work light 1 are simple and convenient, improving the work efficiency of maintenance personnel.

[0032] The work light bracket provided in this application can be installed on the side and rear of the frame of a mining dump truck, or on the roof and front of the truck, for cargo lighting and auxiliary lighting during maintenance. When installed on the vehicle, no additional personnel are needed to support the work light 1 during maintenance, and the work light 1 does not need to be placed in the field. This not only saves manpower, but also avoids the problem of unstable placement of the work light 1 in the field, which affects the lighting.

[0033] The work light bracket provided in this application can also be installed at a suitable location on the aircraft beam. Although airports have lighting equipment, when it comes to specific maintenance locations, the distant lighting equipment is insufficient to illuminate or light up the maintenance location, while handheld lights limit the maintenance capabilities of maintenance personnel.

[0034] A specific application example is as follows: When a vehicle breaks down in a mining area or in the field, first pull out the quick-connect positioning pin 505 until it disengages from the indexing hole 38. Then, rotate the work light 1 to illuminate the suspected fault point. Once the fault point is located, stop rotating the work light 1, and the quick-connect positioning pin 505 falls and inserts into the corresponding indexing hole 38. This frees up the maintenance personnel's hands for inspection, greatly shortening the diagnosis and repair time. Maintaining heavy machinery requires a high degree of precision, such as tightening huge bolts, inspecting small cracks, or connecting complex wiring. Sufficient lighting is fundamental to ensuring maintenance quality and preventing misoperation.

[0035] In the above technical solution, the positioning hole can be set on the mounting bracket 3 or the rotating bracket 2. Correspondingly, the indexing hole 38 is set on the rotating bracket 2 or the mounting bracket 3. The more indexing holes 38 are set, the more lighting angles the work light bracket can adjust.

[0036] It should also be noted that since using a rotating shaft 4 to connect the two components is a conventional technical means, and the through holes 37 on the mounting bracket 3 and the rotating bracket 2 have the same structure, the through holes 37 on different components will not be named and labeled separately in this article.

[0037] In some embodiments, see Figure 3 As shown, the angle adjustment and positioning structure 5 also includes: a fixed housing 502, an elastic element 503, and an adjusting lever 501. The fixed housing 502 is covered on the positioning hole of the rotating frame 2 or the mounting frame 3. The elastic element 503 is elastically limited within the fixed housing 502. The adjusting lever 501 passes through the fixed housing 502 and the elastic element 503, and is fixedly connected to the quick-connect positioning pin 505 that passes through the positioning hole.

[0038] When the illumination angle of the work light 1 needs to be adjusted, lifting the adjusting lever 501 compresses the elastic element 503, causing the quick-connect positioning pin 505 to disengage from the indexing hole 38. Rotating the rotating frame 2 allows adjustment of the illumination angle of the work light 1. When the illumination angle of the work light 1 is adjusted to the desired lighting position, the adjusting lever 501 is released. Under the elastic force of the elastic element 503, the quick-connect positioning pin 505 passes through the coaxial indexing hole 38. The quick-connect positioning pin 505 is pressed in place by the elastic force of the elastic element 503 and will not disengage from the indexing hole 38 and the positioning hole, thus achieving reliable positioning of the work light 1. The operation is simple and convenient.

[0039] Therefore, by restricting the elastic element 503 through the fixed housing 502, and by elastically pressing the quick-connect positioning pin 505 with the elastic element 503, the quick-connect positioning pin 505 can be prevented from coming out of the indexing hole 38, thus ensuring the reliability of the positioning of the work light 1.

[0040] When the positioning hole is set on the rotating frame 2, the fixed housing 502 is welded or fastened to the rotating frame 2 by bolts; when the positioning hole is set on the mounting frame 3, the fixed housing 502 is installed on the mounting frame 3.

[0041] The elastic element 503 is preferably a spring. The space inside the fixed housing 502 needs to allow the spring to maintain a certain degree of compression elasticity so as to keep the quick-connect positioning pin 505 pressed at all times.

[0042] In some embodiments, see Figure 3 As shown, the angle adjustment positioning structure 5 also includes a mounting plate 504 fixed to the rotating frame 2 or the mounting frame 3. The fixed housing 502 is fixed to the mounting plate 504, and the mounting plate 504 has a pin hole through which the quick-connect positioning pin 505 passes. This design allows the angle adjustment positioning structure 5 to be assembled as a whole before being fixed to the rotating frame 2 or the mounting frame 3. This is because the mounting plate 504 has a limiting constraint effect on the quick-connect positioning pin 505. Without the positioning structure with the mounting plate 504, the elastic element 503 and the quick-connect positioning pin 505 would lack restraint. When the positioning structure is removed, the elastic element 503 would be unrestrained and would be stretched under the weight of the quick-connect positioning pin 505, or the end cap of the quick-connect positioning pin 505 would come out of the fixed housing 502, which would make assembly inconvenient.

[0043] Regarding the issue of the work light 1 bracket being easily damaged when it comes into contact with obstacles, the following factors are considered: Currently, the rigid bracket of the work light 1 is generally rigidly connected to the vehicle frame. However, the road conditions in mining areas are complex, with frequent vibrations and impacts. The long cantilever structure formed between the rigid bracket and the vehicle frame easily concentrates stress and transfers it to the vehicle frame. Long-term use may lead to damage to the vehicle frame, affecting the overall structural safety of the vehicle. In addition, because the rigid bracket is a rigid, integral design, partial damage often requires replacement of the entire bracket, which is not only cumbersome to repair but also significantly increases maintenance costs. Therefore, the existing work light 1 bracket has limitations in terms of adaptability, durability, and economy, and a more flexible, reliable, and easy-to-maintain solution is urgently needed. The technical solution adopted in this application can solve the problem of requiring complete replacement of the rigid bracket when partial damage occurs.

[0044] See Figure 3 As shown, the technical solution adopted in this embodiment is to replace the material of the quick-connect positioning pin 505 with a low-strength material. The quick-connect positioning pin 505 is made of nylon or polyethylene. The mounting bracket 3 and the rotating bracket 2 are made of stainless steel or alloy steel, which needs to ensure the firmness of the connection with the vehicle frame and the support strength for the work light 1. When the vehicle is moving, if the rotating bracket 2 of the work light 1 touches an obstacle, the contact force on the rotating bracket 2 can be broken at the low-strength quick-connect positioning pin 505, thereby unlocking the rotating bracket 2. Under the impact of the force, the rotating bracket 2 can rotate, thereby avoiding the obstacle and preventing damage to the rotating bracket 2. It also prevents the contact force from being transmitted to the vehicle frame due to the rigidity of the rotating bracket 2, causing damage to the vehicle frame. Therefore, the quick-connect positioning pin 505 of this application is made of a low-strength material, forming a weak link. When the rotating bracket 2 is subjected to force, the weak link first collapses and absorbs energy and is damaged. In this way, the unlocked rotating bracket 2 can rotate to avoid the obstacle and avoid damage, thereby protecting the work light 1, the rotating bracket 2, the mounting bracket 3 and the vehicle frame from damage.

[0045] Since only the quick-connect positioning pin 505 was damaged, while other components were protected, it is not necessary to replace the entire bracket. Only the quick-connect positioning pin 505 needs to be replaced. If the fixed housing 502 is bolted, simply open the fixed housing 502, remove the end cap on one side of the fixed housing 502, insert the new quick-connect positioning pin 505, and then reassemble. This can greatly reduce maintenance costs.

[0046] In some embodiments, see Figure 3As shown, the lower end of the adjusting lever 501 is threadedly connected to the quick-connect positioning pin 505. This technical solution, as one connection method between the adjusting lever 501 and the quick-connect positioning pin 505, involves the quick-connect positioning pin 505 passing through a pin hole on the mounting plate 504, then inserting the elastic element 503 into the fixed housing 502. The adjusting lever 501 then passes through the fixed housing 502, through the elastic element 503, and is threadedly connected to the quick-connect positioning pin 505. Finally, the fixed housing 502 is welded or bolted to the mounting plate 504. This threaded connection method facilitates the removal of the adjusting lever 501 from the quick-connect positioning pin 505 after damage, eliminating the need to replace the adjusting lever 501, reducing maintenance costs, and simplifying assembly.

[0047] The fixed housing 502 can also be snapped onto the mounting plate 504, and the adjusting lever 501 can also be welded or snapped onto the quick-connect positioning pin 505.

[0048] In some embodiments, see Figure 3 As shown, a handwheel is provided at the upper end of the adjusting lever 501 for easy lifting. By providing a handwheel at the end of the adjusting lever 501, the surface area of ​​the upper end of the adjusting lever 501 is increased, thereby facilitating the operation of lifting the adjusting lever 501 by maintenance personnel.

[0049] As mentioned above, there is a risk that the work light 1 bracket may come into contact with obstacles while driving. Currently, the work light 1 is generally exposed outside the bracket, and there is a risk that the work light 1 may directly come into contact with obstacles while driving. Direct force on the work light 1 may lead to damage. Based on the protection of the work light 1, the bracket provided in this application includes a mounting bracket 3 and a rotating bracket 2, which, when connected, form a hollow cavity protecting the work light 1. The bracket on which the work light 1 relies first comes into contact with obstacles, thus protecting the work light 1. The technical solution is as follows: In some embodiments, see Figures 1 to 2 , Figure 4 As shown, the mounting frame 3 has a first mounting part 31 and a second mounting part 32 connected to the rotating frame 2, and a third mounting part 33 connected to the vehicle frame; both the first mounting part 31 and the second mounting part 32 are provided with through holes 37; the rotating frame 2 has a U-shaped frame structure, with a first connecting end 21 and a second connecting end 22 correspondingly connected to the first mounting part 31 and the second mounting part 32, both of which are provided with through holes 37; an indexing hole 38 is provided on the third mounting part 33; a positioning hole is provided on the second connecting end 22; after the rotating frame 2 and the mounting frame 3 are connected, they form a hollow cavity, and the work light 1 is installed in the hollow cavity.

[0050] In the above technical solution, the rotating frame 2 and the mounting frame 3 form a frame structure. The enclosed hollow cavity not only protects the work light 1, but also features a simple structure. The mounting frame 3 has three mounting parts, while the rotating frame 2 only requires two connecting ends, connected by two rotating shafts 4. The entire support structure is simple, easy to assemble, and the illumination angle adjustment is also simple and convenient. This not only reduces manufacturing costs but also improves maintenance efficiency.

[0051] In some embodiments, see Figures 1 to 2 , Figure 4 As shown, the rotating frame 2 is constructed from bent sheet metal to form the first connecting end 21 and the second connecting end 22 arranged in parallel; the mounting frame 3 includes a first support plate 34 and a second support plate 36 vertically connected to the first support plate 34. The two ends of the first support plate 34 form a first mounting part 31 and a third mounting part 33, and the end of the second support plate 36 is bent to form a second mounting part 32.

[0052] In the above technical solution, the rotating frame 2 can be made by bending a stainless steel plate to form a U-shaped frame with one end open. The second support plate 36 of the mounting frame 3 can seal this opening, so that the rotating frame 2 and the mounting frame 3 form a closed hollow cavity, which provides reliable protection for the work light 1 and avoids the risk of the work light 1 being directly impacted. This bracket structure is simple and easy to install on the vehicle frame. Generally, mounting holes 35 are provided on the third mounting part 33 of the mounting frame 3.

[0053] In some embodiments, see Figures 1 to 2 , Figure 4 As shown, the first connecting end 21 and the second connecting end 22 of the rotating frame 2 are limited between the first mounting part 31 and the second mounting part 32. Since the rotating frame 2 is an open U-shaped frame, the bending part has a certain elastic deformation, and the opening is prone to deformation and expansion. By limiting these two connecting ends between the two mounting parts, the constraint on the rotating frame 2 can reduce the axial constraint force of the rotating shaft 4 and improve the firmness of the connection between the rotating frame 2 and the mounting frame 3.

[0054] Based on the same inventive concept, this application also provides a wide-body mining dump truck, on which the aforementioned work light 1 bracket is installed on the chassis.

[0055] Because this wide-body mining dump truck uses this type of work light 1 bracket, the work light 1 can be quickly rotated and adjusted, saving maintenance time. The frame-type rotating bracket 2 protects the work light 1 and reduces damage to the work light 1. The low-strength quick-connect positioning pin 505 breaks when it touches an obstacle, protecting the work light 1, the work light 1 bracket, and the vehicle frame. Moreover, replacing the quick-connect positioning pin 505 separately after damage can reduce maintenance costs, thereby improving the overall use value of the vehicle.

[0056] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
