Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of building construction, in particular to a building construction lighting device. BACKGROUND

[0002] The building construction lighting device is a core auxiliary equipment in the whole cycle construction stage of building engineering, mainly applied to civil construction, indoor decoration, equipment installation and other links, used to solve the problem of insufficient natural light in the construction environment (such as night construction, basement / closed space construction) or dim light in local operation surface, to provide clear visual environment for construction personnel, to ensure that they can accurately identify operation details (such as steel bar binding spacing, pipeline interface butt joint, wall plastering flatness, etc.), which is the key equipment to ensure construction accuracy and avoid safety risks (such as tool injury, structure deviation). Its typical structure usually includes a light emitting assembly (usually using LED lamp beads, energy-saving halogen lamps and other light sources), a support structure (such as a telescopic metal lamp stand, a folding tripod, a wall-mounted bracket) for carrying the lamp body, a power supply module (such as a power cord connected to the mains, a rechargeable lithium battery pack) and basic protection components (such as a waterproof and dustproof shell, a collision-resistant buffer layer), which can be flexibly arranged according to the construction scene and widely adapted to various construction sites such as residential buildings, industrial plants, municipal roads and underground engineering.

[0003] In actual construction application, the existing building construction lighting device has significant functional limitations. Since the lighting range of the existing device is usually fixed by the optical design of the light source itself (such as a wide-angle light covering a diameter of 3-5 meters, a narrow-angle light covering a diameter of 1-2 meters), if the lighting coverage area needs to be adjusted (such as switching from the large-scale lighting of wall plastering operation to the local lighting of ground pipeline laying), it can only be achieved by manually moving the lamp body, adjusting the placement position of the lamp stand or changing the height of the lamp stand. After the lamp body position is fixed again, it is turned on. The operation process is complicated. For smaller operation positions that need to be finely operated in construction (such as steel node welding points, wall crack repair positions, pipeline interface sealing treatment, etc.), the existing device either has insufficient light intensity due to wide-angle light or is difficult to form targeted strong light focus because the narrow-angle light range is still larger than the target area (such as a light covering a diameter of 1 meter, while the target operation point is only a local part of 5-10 centimeters). In order to improve the lighting effect of small positions, construction personnel often need to manually adjust the placement position of the lamp body repeatedly (such as gradually moving the lamp stand closer to the operation point until the brightness meets the standard), and in some scenes, even a person needs to hold the lamp body to maintain lighting. Not only does this interrupt the normal construction process, but it also may cause inconvenience due to the obstruction of the lamp body to the operation space. Therefore, repeated adjustment seriously affects the construction efficiency and the practicability of the device. The applicability of the existing lighting device in fine construction scenes (such as fine decoration and precise equipment installation) is limited, the overall practicability is significantly reduced, and it is difficult to match the requirements of modern building construction for high efficiency and fine operation.

[0006] A bearing support is fixedly installed on one side of the inner wall of the fixed frame near the four corners, a support shaft is rotatably installed on one side of the inner wall of the bearing support, a lighting lamp is installed on one side of the middle part of the outer surface of the support shaft, and an adjusting mechanism is arranged outside the fixed frame and used for adjusting the light angles of the plurality of lighting lamps.

[0007] The adjusting mechanism comprises a placing rack, the placing rack is fixedly installed at the other side of the bottom of the fixed frame, a driving part is arranged on the upper surface of the placing rack, a connecting piece is installed at one side of the output end of the driving part, and a plurality of movable connecting rods are rotatably installed on the outer surface of the connecting piece.

[0008] An installation seat is fixedly installed on one side of the lighting lamp, and the movable connecting rods are rotatably installed in the installation seat.

[0009] The outer surface of the protective cover is further provided with a spotlight assembly for gathering the lighting light generated by the lighting lamp.

[0010] Further, the spotlight assembly comprises a cross support frame, the cross support frame is arranged at the opening on one side of the protective cover, a guide sliding groove is formed on one side of the cross support frame, a transparent spotlight plate is movably arranged on one side of the cross support frame, a damping support piece is symmetrically fixedly connected to one side of the edge of the transparent spotlight plate, and a connecting structure is further arranged on the outer surface of the cross support frame and used for fixing the cross support frame on the outer surface of the protective cover.

[0011] Further, the connecting structure comprises a fixed support rod, the fixed support rod is fixedly installed at the four corners on one side of the cross support frame, a plurality of fixed pieces are fixedly installed on the outer surface of the protective cover, an external thread is formed on one side of the edge of the fixed support rod, a fastening nut is threadedly connected to the outer surface of the external thread, and one side of the fastening nut abuts against the fixed piece.

[0012] Further, a groove is formed in the middle part of the outer surface of the damping support piece, the outer surface of the damping support piece is located inside the guide sliding groove on one side, and the guide sliding groove and the damping support piece are coupled to each other.

[0013] Further, a through hole is formed in the middle of one end of the fixing part, and the fixing support rod is located inside the through hole.

[0014] Further, a plurality of fixing grooves are formed on one side of the outer surface of the connecting part, and the movable connecting rod is rotatably installed inside the fixing grooves, and the movable connecting rod and the fixing grooves are mutually embedded.

[0015] Further, the number of the lighting lamps is four, and the middle of one side of the outer surface of the lighting lamp is located inside the bearing support, and the bearing support and the lighting lamp are mutually embedded.

[0016] Compared with the prior art, the building construction lighting device provided by the application has the following beneficial effects:

[0017] 1、The cooperation of the adjusting mechanism (the placing rack, the driving part, the connecting part and the movable connecting rod) and the lighting lamp realizes flexible angle adjustment of multiple lighting lamps. When it is necessary to adapt to high wall surface (such as 2m plastered surface) or ground pipeline construction, the lamp body does not need to be manually carried and the lamp stand does not need to be disassembled, but only the telescopic action (response time ≤2 seconds) of the driving part can drive the lighting lamp to synchronously rotate around the supporting shaft in the bearing support, and the independent angle fine adjustment of a single lighting lamp can also be realized by separately controlling part of the driving assembly. Compared with the complicated process (single adjustment time 1-2 minutes) in the prior art, the single operation time of the adjusting mode is shorter, and the adjusting process does not interrupt the construction, effectively avoids the delay of construction period caused by repeated adjustment of lighting, and significantly improves the construction continuity and the lighting adjustment efficiency.

[0018] 2、The spotlight assembly outside the protective cover realizes strong light focusing on a small operation point through the structural cooperation of "cross support frame positioning, transparent spotlight plate refraction and damping support fixing". The transparent spotlight plate adopts high-transmittance (≥90%) optical material, can gather the dispersed light of the lighting lamp into a strong light area with a diameter of 5-10cm, and can clearly present the details such as the molten pool state of the reinforcement welding point and the depth of the wall crack. At the same time, the coupling design of the damping support and the guide sliding groove makes the transparent spotlight plate smoothly slide along the sliding groove (sliding resistance ≤5N), and can be stably fixed at any position (damping force ≥1.2 times the weight of the transparent spotlight plate) after being loosened, without the need for a person to hold it. When it is necessary to restore large-area lighting, the transparent spotlight plate only needs to be pushed to the edge of the cross support frame to release the spotlight state, which takes into account the dual needs of fine focusing and large-area lighting, and greatly improves the practicability of the device in fine decoration, equipment precise installation and the like.

[0019] 3. The present invention uses casters at the bottom of the mobile vehicle to facilitate the quick movement of the device to different construction areas, and the braking function ensures that the device does not slip during operation; the generator on the mobile vehicle can provide stable power supply, without relying on temporary on-site power lines, and is suitable for remote construction areas without mains power supply (such as basements and outdoor unfinished construction sites), thus improving the device's adaptability to different scenarios.

[0029] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0030] As attached Figure 1 To be continued Figure 6 As shown:

[0031] Example 1:

[0032] This invention provides a building construction lighting device, including a mobile vehicle 1, a generator 2 installed on the upper surface of the mobile vehicle 1, a support base 3 fixedly installed on one side of the top of the mobile vehicle 1, a support column 4 installed on the upper surface of the support base 3, a fixed frame 5 fixedly installed on the upper surface of the support column 4, and a protective cover 6 integrally formed on one side of the fixed frame 5.

[0033] Bearing supports 7 are fixedly installed on one side of the inner wall of the fixed frame 5 near the four corners. A support shaft 8 is rotatably installed on one side of the inner wall of the bearing support 7. A lighting lamp 9 is installed in the middle of one side of the outer surface of the support shaft 8. There are four lighting lamps 9. The middle of one side of the outer surface of the lighting lamp 9 is located inside the bearing support 7. The bearing support 7 and the lighting lamp 9 are interlocked. An adjustment mechanism is provided on the outside of the fixed frame 5 to adjust the illumination angle of the multiple lighting lamps 9.

[0034] The adjustment mechanism includes a placement frame 12, which is fixedly installed at the bottom of the other side of the fixed frame 5. A drive unit 13 is provided on the upper surface of the placement frame 12. The drive unit 13 is an electric telescopic rod. A connector 14 is installed at the output end of one side of the drive unit 13. Several movable connecting rods 11 are rotatably installed on the outer surface of the connector 14.

[0035] A plurality of fixing grooves are provided on one side of the outer surface of the connector 14. The movable connecting rod 11 is rotatably installed inside the fixing groove through a bearing, and the movable connecting rod 11 and the fixing groove are interlocked.

[0036] A mounting base 10 is fixedly installed on one side of the lighting lamp 9, and a movable connecting rod 11 is rotatably installed inside the mounting base 10 on one side.

[0037] The outer surface of the protective cover 6 is also equipped with a light-concentrating component to concentrate the lighting light generated by the lighting lamp 9.

[0038] Working principle: First, the staff prepares and sets up the device in advance. By pushing the mobile vehicle 1 to the target construction area (such as the indoor wall plastering work area), they observe whether the ground is flat and ensure that the mobile vehicle 1 has no risk of tilting. Multiple support rollers on the bottom of the mobile vehicle 1 provide stable support for the entire equipment, making it easy for people to move the mobile vehicle 1. At this time, the cast iron support base 3 on the upper surface of the mobile vehicle 1 can enhance the overall stability and prevent the device from tipping over when adjusting the support column 4 later.

[0039] Adjust the support column 4 according to the construction height requirements: If you need to illuminate a 2m high plastering area on the wall, first loosen the telescopic locking knob in the middle of the support column 4 clockwise with your right hand (the outer surface of the knob has anti-slip texture to increase hand friction), hold the fixed frame 5 at the top of the support column 4 with your left hand, and slowly pull the inner rod of the support column 4 upward until the scale line shows a height of 2m, then tighten the knob counterclockwise. After hearing a "click" sound, confirm that it is locked. At this time, the support column 4 has no axial loosening. If you need to illuminate the construction area of ​​the ground pipeline, shorten the support column 4 to 1.2m and lock it in the same way to ensure that the initial height of the four lights 9 is adapted to the working surface.

[0040] Start the generator 2 on the upper surface of the mobile vehicle 1. After the generator 2 is running stably, turn on the four lights 9 through the control switch. At this time, the lights 9 are in the initial horizontal illumination state. After the light passes through the transparent protective cover 6, it covers a large area of ​​3 to 5 meters in front of the fixed frame 5, which meets the conventional construction lighting needs.

[0041] When the lighting angle needs to be adjusted to suit different work surfaces, the operator uses the adjustment mechanism to switch angles. First, the adjustment direction is determined according to the work requirements (e.g., the angle needs to be adjusted upwards for plastering high up on a wall, and downwards for pipeline construction on the ground). The drive unit 13 is started by the control button next to the generator 2. Second, if the angle needs to be adjusted upwards, the output end of the drive unit 13 (electric telescopic rod) extends outwards, driving the connecting piece 14 to move away from the fixed frame 5. When the connecting piece 14 moves, the movable connecting rod 11 in the fixed groove on its outer surface rotates around the bearing, while simultaneously pulling the mounting seat 10 on the lighting lamp 9 outwards. Since the middle of the outer surface of the lighting lamp 9 is embedded in the bearing support 7, and the support shaft 8 can rotate flexibly within the bearing support 7, the lighting lamp 9 can be adjusted accordingly. When the mounting base 10 is under force, it drives the lighting lamp 9 to rotate upward around the support shaft 8 until the light angle covers the high working area of ​​the wall (such as a 2m high plaster surface). At this time, the drive unit 13 is turned off, and the output end of the drive unit 13 remains extended, fixing the angle of the lighting lamp 9. If the angle needs to be adjusted downward: the drive unit 13 (electric telescopic rod) is activated to retract the output end, the connector 14 moves towards the fixed frame 5, the movable connecting rod 11 pushes the mounting base 10, and the lighting lamp 9 rotates downward around the support shaft 8. The light gradually focuses on the ground until it covers the pipeline construction area. The drive unit 13 is then turned off to complete the adjustment. The entire process does not require moving the lamp body or the mobile vehicle 1. The lighting angle can be quickly switched using only the drive unit 13, avoiding interruption of the construction process.

[0042] After the work is completed, the staff first turn off the lights 9, then stop the generator 2, release the brakes on the casters, and push the mobile vehicle 1 to the next work area or warehouse for storage, thus completing this basic lighting operation.

[0043] Example 2:

[0044] This embodiment is basically the same as the previous embodiment, except that the light-concentrating component includes a cross support frame 15, which is located at an opening on one side of the protective cover 6. A guide groove 16 is provided on one side of the cross support frame 15, and a transparent light-concentrating plate 21 is movably arranged on one side of the cross support frame 15. A damping support member 22 is symmetrically fixed to one side of the transparent light-concentrating plate 21. A connecting structure is also provided on the outer surface of the cross support frame 15 for fixing the cross support frame 15 to the outer surface of the protective cover 6.

[0045] The connection structure includes a fixed support rod 18, which is fixedly installed at the four corners of one side of the cross support frame 15. Several fasteners 17 are fixedly installed on the outer surface of the protective cover 6. An external thread 19 is provided on one side of the fixed support rod 18. A fastening nut 20 is threaded on the outer surface of the external thread 19. One side of the fastening nut 20 abuts against the fastener 17.

[0046] A groove is provided in the middle of one side of the outer surface of the damping support 22. One side of the outer surface of the damping support 22 is located inside the guide groove 16. The guide groove 16 and the damping support 22 are coupled to each other.

[0047] The fixing member 17 has a through hole in the middle of one end, and one side of the fixing rod 18 is located inside the through hole. The fixing rod 18 and the through hole are fitted together.

[0048] Working principle: First, based on Example 1, the staff installs and adjusts the focusing component to meet the needs of refined operations (such as welding of steel bar nodes and repair of wall cracks). First, take out the cross support frame 15 and align the fixed support rods 18 on one of its four corners with the fixing parts 17 on the outer surface of the protective cover 6. Since the fixing parts 17 have through holes in the middle and the fixed support rods 18 fit into the through holes, slowly insert the fixed support rods 18 into the through holes until the cross support frame 15 fits tightly against the opening of the protective cover 6. Then, put the fastening nuts 20 on the external threads 19 of each fixed support rod 18 and tighten the fastening nuts 20 clockwise by hand until one side of the fastening nut 20 abuts against the outer surface of the fixing parts 17, and the cross support frame 15 is stably fixed without loosening or shaking.

[0049] Check the installation status of the transparent light-concentrating plate 21. The damping support 22 on one side of the transparent light-concentrating plate 21 is embedded in the guide groove 16 of the cross support frame 15 and the two are coupled to each other. Push the transparent light-concentrating plate 21 by hand to confirm that it can slide smoothly along the guide groove 16 and can be fixed in any position after being released (the friction between the groove of the damping support 22 and the inner wall of the guide groove 16 is greater than the weight of the transparent light-concentrating plate 21).

[0050] When performing small-scale high-intensity light focusing operations, first observe the target work point (such as a 5cm wide crack in the wall), pinch the edge of the transparent focusing plate 21 with your hand, and push it towards the crack; the damping support 22 slides along the guide groove 16, driving the transparent focusing plate 21 to move precisely to the front of the crack, release the transparent focusing plate 21, and the damping support 22 fixes it in the current position; then, turn on the lighting 9, and the light passes through the transparent protective cover 6 and is refracted and focused by the transparent focusing plate 21 to form a high-intensity light area with a diameter of 5-10cm, which precisely covers the crack repair area, and the construction personnel can clearly observe the details of the crack (such as depth and width) and carry out the repair operation; if it is necessary to switch to other small work points (such as adjacent steel bar welding points), push the transparent focusing plate 21 along the guide groove 16 again to the front of the welding point, the transparent focusing plate 21 is automatically fixed, and the light is synchronously focused on the new work point without adjusting the angle of the lighting 9 or moving the device.

[0051] When spotlighting is no longer needed (e.g., to restore wide-area lighting), the worker pushes the transparent spotlight plate 21 to the edge of the cross support frame 15. The transparent spotlight plate 21 no longer blocks most of the light, and the lighting lamp 9 restores wide-area illumination. After the work is completely finished, the fastening nut 20 is loosened counterclockwise, the cross support frame 15 is removed, and the construction dust on the surface of the transparent spotlight plate 21 is cleaned for the next use.

[0052] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
