Description

Technical Field

[0001] This utility model relates to the field of positioning lighting devices, and in particular to a positioning lighting device for use in confined spaces. Background Technology

[0002] Currently, during the maintenance and repair of refractory materials in rotary kilns, it is necessary to enter the kiln. Due to insufficient lighting in the working space, only portable lighting fixtures of 36V or less or explosion-proof lights can be used for on-site illumination. When the main construction work involves installing and welding precast bricks and anchor nails, ensuring the welding quality of the precast bricks on-site is a major challenge. The rotary kiln is a confined space with a harsh environment and insufficient lighting.

[0003] The number of anchors on the precast bricks is four times the number of precast bricks, resulting in a huge number of anchors to be welded. Furthermore, the welding of precast bricks has detailed technical requirements: the welding point must be approximately 10mm away from the precast brick; the weld length on one side must be ≥30mm; the height must be ≥8mm; welding cracks and incomplete welds are not allowed; and welding quality must be guaranteed. Insufficient on-site lighting, confined working space, and the presence of toxic and harmful gases further complicate the on-site welding of precast bricks.

[0004] Through preliminary on-site welding quality inspection, it was found that due to insufficient lighting in the narrow construction area and continuous operation in confined space for a long time, welders were prone to forgetting the technical instructions. As a result, there were many welding points that were not about 10mm away from the precast bricks, which is a technical requirement. There were also a lot of undercuts, which damaged the anchors of the precast bricks, causing their strength to drop significantly and posing a risk of falling off later. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a positioning lighting device for confined spaces. Its advantages are that it can provide positioning and lighting functions, improve the on-site construction environment, reduce construction intensity, improve construction quality, and avoid the risk of falling off later.

[0022] Reference Figures 1 to 3 This utility model discloses a positioning lighting device 1 for confined spaces, comprising a clamp 10 and at least one positioning lighting component 20. The positioning lighting component 20 is disposed on the clamp 10 and can slide along the X direction of the clamp 10 to adjust its position. The positioning lighting component 20 can emit a linear laser and lighting light.

The clamp 10 is used to clamp a row of precast bricks 2. By setting the positioning lighting component 20, the positioning lighting component 20 provides positioning and lighting functions, improves the on-site construction environment, reduces construction intensity, improves construction quality, and avoids the risk of later detachment.

[0023] The technical requirements for welding precast brick 2 are as follows: the welding starting point should be approximately 110mm away from precast brick 2; the welding length on one side should be ≥30mm, and the height ≥8mm; both sides of the anchoring nail should be fully welded with an edge wrapping, forming a "U"-shaped weld. The welding machine current must not be too high, and the anchoring nail of precast brick 2 must not be melted; the current should be controlled below 160A. Welding cracks and incomplete welds are not allowed; welding quality must be guaranteed, and A302 welding rods should be used.

[0024] It should be noted that the intersection of the laser beam and the anchor is the welding start point, and therefore the preset distance is 10mm.

[0026] Furthermore, in this embodiment, the clamp 10 includes two clamping units 11, which are spaced apart along the Y direction, and the opposite ends of the positioning lighting component 20 are slidably connected to the two clamping units 11 respectively.

Release the handle 1111, under the action of the restoring force of the helical spring 1114, the helical spring 1114 drives the rotating part 1113 to rotate counterclockwise, so that the first adsorption unit 1115 is adsorbed on the end of the whole row of precast bricks 2.

[0032] The handle 1111 is made of round steel pipe, and the length of the handle 1111 is 1 / 2 of the length of the inclined rod 1112. A rubber protective sleeve is fitted on the outer peripheral wall of the handle 1111, which increases the friction.

The sliding sleeve 1121 is sleeved on the end of the connecting rod 113 away from the first clamping assembly 111, and the sliding sleeve 1121 can slide along the connecting rod 113. The sliding sleeve 1121 slides along the connecting rod 113 to drive the clamping part 1122 to move, so as to adjust the size of the opening end of the clamping unit 11. When the sliding sleeve 1121 slides to a preset position, the sliding sleeve 1121 is locked by the fastening bolt.

[0041] The clamping part 1122 is made of steel bars. The outer peripheral wall of the sliding sleeve 1121 is provided with a threaded hole, which communicates with the cavity of the sliding sleeve 1121. When the sliding sleeve 1121 slides to the preset position, one end of the fastening bolt is inserted into the sliding sleeve 1121 through the threaded hole and abuts against the connecting rod 113.

[0042] Furthermore, in this embodiment, the clamping part 1122 includes a first horizontal fixing rod 11221, a second horizontal fixing rod 11222, a first vertical rod 11223, and a second vertical rod 11224.

By rotating the laser module 224, the position of the line laser is adjusted so that the intersection of the line laser with the anchor on the precast brick 2 and the side wall of the precast brick 2 are spaced at a preset distance.

[0048] Specifically, the centerline of the sleeve 221 is set parallel to the X direction. After the sleeve 221 slides along the connecting rod 113 to the designated position, the sleeve 221 is locked by the connecting bolt to prevent the sleeve 221 from moving along the connecting rod 113.

[0049] The lighting module 223 uses a flexible tube lamp, and the position of the light source can be adjusted by moving the flexible tube as needed.

[0050] Furthermore, in this embodiment, the mounting platform 222 includes a horizontal plate 2221, a first vertical plate 2222, and a second vertical plate 2223.

[0051] In this embodiment, the laser module 224 includes a laser module 2241, a collar 2242, and a fixing bolt 2243. The laser module 2241 is mounted on the collar 2242, which is rotatably connected to the mounting platform 222 via a rivet 2244. The collar 2242 rotates about the center line of the rivet 2244. When the collar 2242 is rotated, it drives the laser module 2241 to rotate. When the laser module 2241 rotates to the predicted position, one end of the fixing bolt 2243 passes through the outer wall of the mounting platform 222 on the side away from the rivet 2244 and abuts against the outer peripheral wall of the collar 2242 to lock the collar 2242.

[0052] Specifically, the collar 2242 is set in the mounting cavity. The collar 2242 is rotatably connected to the second vertical plate 2223 by the rivet 2244. When the collar 2242 is rotated, the collar 2242 drives the laser module 2241 to rotate. When the laser module 2241 rotates to the predicted position, one end of the fixing bolt 2243 passes through the first vertical plate 2222 and is inserted into the mounting cavity, and abuts against the outer peripheral wall of the collar 2242.

[0053] The horizontal plate 2221 is provided with a first battery box 225 and a second battery box 226.

The laser module 2241 and the battery in the second battery box 226 are connected to the lighting module 223 through a second wire.

[0054] Specifically, the laser module 2241 adopts a single-line laser module 2241.

[0055] In this embodiment, a rubber pad is provided at the end of the fixing screw that abuts against the collar 2242, thereby increasing the friction.

[0056] The operation of the positioning lighting device 1 for confined spaces provided in this embodiment is as follows: First, adjust the position of the second clamping component 112 according to the size of the precast bricks 2 to make the distance between the two sides of the opening end of the clamping unit 11 less than the size of the entire row of precast bricks 2 by 1-2 cm; press the handle 1111, at which time the handle 1111 drives the rotating part 1113 to rotate clockwise, the spiral spring 1114 is stretched, the opening end of the clamping unit 11 is enlarged, and the entire row of precast bricks 2 is placed in the clamping unit 11; release the handle 1111, under the action of the restoring force of the spiral spring 1114, the spiral spring 1114 drives the rotating part 1113 to rotate counterclockwise, so that the first adsorption unit 1115 adsorbs the end of the entire row of precast bricks 2, so that the clamp 10 is fixed on the precast bricks 2; turn on the laser module 2241 and the lighting module 223. The lighting is a flexible tube light. The position of the light source can be adjusted by moving the flexible tube as needed. The rotating collar 2242 drives the laser module 2241 to rotate. When the laser module 2241 rotates to the predicted position, one end of the fixing bolt 2243 passes through the outer wall of the mounting platform 222 away from the rivet 2244 and abuts against the outer peripheral wall of the collar 2242 to lock the collar 2242. At this time, the intersection of the laser beam emitted by the laser module 2241 and the anchor on the precast brick 2 is 10mm away from the side wall of the precast brick 2. Then, the precast brick 2 is welded. After welding one precast brick 2, it is only necessary to slide the sleeve 221 to the next precast brick 2 and make appropriate minor adjustments to the laser angle for welding. After the construction is completed, the lighting module 223 and the laser module 2241 are turned off, and the handle 1111 is pressed to increase the opening end of the clamping unit 11. The device is then removed, disassembled, stored and reused, saving resources and reducing costs.

[0057] This application provides a positioning lighting device 1 for confined spaces, including a clamp 10 and at least one positioning lighting component 20. The positioning lighting component 20 is disposed on the clamp 10 and can slide along the X direction of the clamp 10 to adjust its position. The positioning lighting component 20 can emit a linear laser and lighting light. The linear laser is used to intersect with the anchor on the precast brick 2, and the intersection point of the linear laser and the anchor is spaced at a preset distance from the side wall of the precast brick 2. The clamp 10 is used to clamp a row of precast bricks 2. By setting the positioning lighting component 20, the positioning lighting component 20 provides positioning and lighting functions, improves the on-site construction environment, reduces construction intensity, improves construction quality, and avoids the risk of later detachment.
