Description

Technical Field

[0001] This utility model relates to the field of lighting fixture technology, and in particular to a multi-directional lighting fixture device for a mining shotcrete robot. Background Technology

[0002] In coal mine roadway shotcrete support operations, explosion-proof lights are installed on the boom of the shotcrete robot. This is designed to observe the robot's movements, the shotcrete status, and the real-time situation of the sprayed concrete onto the wall. Operators control the shotcrete robot via remote control. The explosion-proof lights on the boom illuminate the work, allowing operators to observe the shotcrete operation. This enables them to adjust the distance between the nozzle and the spray surface, the nozzle's brushing motion, and the required airflow in real time, ensuring shotcrete quality and reducing rebound.

[0003] Explosion-proof lights are typically installed with fixed light stands. Therefore, the lights can only move with the boom, and their illumination area is limited to the length of the boom, making the illumination range relatively fixed and unable to be adjusted according to actual usage needs. While the lighting effect is excellent when the nozzle is directly in front of the boom, it becomes very poor when the nozzle and boom are at a 90° angle. The light still illuminates along the boom, resulting in poor illumination of the nozzle and the sprayed area 0.8-1.5 meters away, even creating blind spots. This affects the judgment of the robotic arm's movements, spray distance, and airflow adjustment, ultimately impacting spray quality and potentially increasing spray rebound. Summary of the Invention

[0004] To address the problem of conventionally installed explosion-proof lights having a single illumination angle and difficulty in flexibly adjusting the illumination direction, this utility model provides a multi-directional lighting fixture for a mining shotcrete robot. This fixture allows the explosion-proof light to be mounted on a multi-directionally swinging fixture, enabling flexible adjustment of the illumination angle and facilitating better and higher-quality shotcrete robot operation.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A multi-directional lighting fixture for a mining shotcrete robot includes an explosion-proof light, a fixture body, and a control unit; The main body of the lamp holder includes a fixed bracket, a lower bracket, a bogie, an upper bracket, and a lamp holder with a swing arm. The lower bracket is set above the fixed bracket, and the bogie is circumferentially connected above the lower bracket. The upper end of the bogie has a "U" shaped cross section, and the upper bracket is rotatably connected above the bogie. The lower end of the upper bracket has an inverted "U" shaped cross section and covers the bogie. The upper bracket is symmetrically provided with lamp holders on both sides, and the lamp holders and the upper bracket are circumferentially connected. The ends of the swing arms on the two lamp holders overlap, and each lamp holder is provided with an explosion-proof lamp, which facilitates the installation of the explosion-proof lamp. The control unit includes a drive component for driving the bogie to rotate in a circular motion, a telescopic component one for driving the upper support to rotate in a pitching motion, and a telescopic component two for synchronously driving the lamp holders on both sides to rotate in a circular motion.

[0006] Furthermore, the lower support includes a lower fixed plate and a rotating sleeve, with one end of the lower fixed plate extending outward from the fixed support and connected to the rotating sleeve; The lower end of the bogie is shaft-shaped and extends into a rotating sleeve to facilitate rotation with the lower support. The driving component is installed at the lower end of the rotating sleeve. The output shaft of the driving component extends into the rotating sleeve and is connected to the bogie to facilitate rotation of the bogie. The driving component and the fixed support are arranged left and right.

[0007] Furthermore, the bogie includes a U-shaped plate, a rotating shaft, and a mounting plate. The U-shaped plate has inner holes on the lower sides and arc-shaped swing grooves on the upper side to provide conditions for the swing of the upper support. The rotating shaft is located at the bottom of the U-shaped plate, and the bogie is rotatably connected to the lower support through the rotating shaft. The mounting plate is horizontally located at one end of the U-shaped plate to facilitate the installation of the telescopic component.

[0008] Furthermore, the upper support includes an inverted U-shaped plate and an upper fixing plate. The inverted U-shaped plate covers the regular U-shaped plate. The lower sides of the inverted U-shaped plate have external holes, and the upper sides have fixing holes, which also provide conditions for the swing of the upper support. The upper fixing plate is set above the inverted U-shaped plate, and the lamp holder is arranged on the upper fixing plate. A pitch shaft is provided between the corresponding inner and outer holes on the bogie and the upper support. The pitch shaft is a bolt structure. A swing shaft is provided between the swing groove and the fixing hole between the bogie and the upper support to facilitate movement along the swing groove. The telescopic component is hinged between the swing shaft and the mounting plate to facilitate driving the swing shaft.

[0009] Furthermore, the lamp holder includes an L-shaped plate and ribs. The ribs are arranged between the two sides of the L-shaped plate to improve the strength of the lamp holder itself. The upper surface of the L-shaped plate is an arc-shaped concave surface that matches the outline of the explosion-proof lamp. A small pivot is provided between one end of the L-shaped plate and the upper bracket. The small pivot is a bolt structure. The other end of the L-shaped plate is hinged to the swing arm. The swing arms on the two lamp holders are close to each other. The second telescopic component is mounted on the upper support. The ends of the second telescopic component and the ends of the two swing arms that overlap are hinged at one point, which makes it easy for the second telescopic component to control the swing of the two lamp holders at the same time.

[0010] Furthermore, the driving component is either a motor or a rotary cylinder, and both the first telescopic component and the second telescopic component are either electric push rods or hydraulic cylinders.

[0011] The beneficial effects of this utility model through the above technical solution are: This utility model features a reasonable structural design. Under the control of the control unit, the main body of the lamp holder can move, allowing for flexible adjustment of the explosion-proof lamp's illumination direction. The drive component controls the simultaneous circular rotation of two explosion-proof lamps, the first telescopic component controls the simultaneous pitching and swinging of the two lamps, and the second telescopic component controls the individual circular rotation of the two lamps. This enables multi-directional illumination of the explosion-proof lamps, increasing the illumination range. Regardless of the spraying state, the robotic arm of the shotcrete robot can easily adjust the illumination direction of the explosion-proof lamps on the arm to adapt to the lighting at the nozzle, facilitating clear observation of the shotcrete effect at the nozzle and on the sprayed surface.

The explosion-proof lamp 1 can be installed on the fixture body. The control unit can drive the fixture body to swing in multiple directions, thereby flexibly adjusting the illumination direction of the explosion-proof lamp 1.

[0019] The main body of the lamp holder includes a fixed bracket 2, a lower bracket 3, a bogie 4, an upper bracket 5, and a lamp holder 7 with a swing arm 6, such as Figure 2 As shown. The fixed bracket 2 is a bracket on the boom of the shotcrete robot, and the main body of the lamp holder is mounted on the boom of the shotcrete robot through the fixed bracket 2.

[0020] A lower support 3 is provided above the fixed support 2. The lower support 3 includes a lower fixed plate 31 and a rotating sleeve 32. The lower fixed plate 31 and the fixed support 2 are bolted together. One end of the lower fixed plate 31 extends outward from the fixed support 2. The rotating sleeve 32 is connected to the outward-extending end of the lower fixed plate 31. The rotating sleeve 32 is arranged vertically.

[0021] A bogie 4 is circumferentially connected above the lower support 3. The bogie 4 can rotate in a circular direction with the rotating sleeve 32 as the rotation center. That is, the lower end of the bogie 4 is shaft-shaped and extends into the rotating sleeve 32.

[0022] The upper section of the bogie 4 is U-shaped. Specifically, the bogie 4 includes a U-shaped plate 41, a hollow rotating shaft 42, and a mounting plate 43, as shown below. Figure 3 As shown. The cross-section of the U-shaped plate 41 is "U" shaped. A rotating shaft 42 is provided at the bottom of the U-shaped plate 41. The bogie 4 is rotatably connected to the lower support 3 through the rotating shaft 42, that is, the rotating shaft 42 extends into the rotating sleeve 32 and is rotatably connected to it.

[0023] An upper support 5 is connected to the bogie 4 for pitch and rotation. The lower end of the upper support 5 has an inverted "U" shaped cross-section and covers the bogie 4. Specifically, the upper support 5 includes an inverted U-shaped plate 51 and an upper fixing plate 52. The inverted U-shaped plate 51 has an inverted "U" shaped cross-section and covers the regular U-shaped plate 41. The upper fixing plate 52 is arranged horizontally above the inverted U-shaped plate 51.

[0024] The upper bracket 5 is symmetrically provided with lamp holders 7 on both sides, that is, the lamp holders 7 are arranged on the upper fixing plate 52. The lamp holders 7 and the upper fixing plate 52 of the upper bracket 5 are circumferentially connected, and the rotation of the two lamp holders 7 is controlled synchronously.

[0025] The lamp holder 7 includes an L-shaped plate 71 and ribs 72. The L-shaped plate 71 consists of a horizontal section and a vertical section. Ribs 72 are arranged between the two sides of the L-shaped plate 71, that is, between the horizontal and vertical sections, to improve the strength of the L-shaped plate 71. A small rotating shaft 8 is provided between one end of the L-shaped plate 71 and the upper fixing plate 52 of the upper bracket 5. The small rotating shaft 8 is a bolt structure, and the lamp holder 7 rotates around the small rotating shaft 8. A swing arm 6 is hinged to the other end of the L-shaped plate 71. The swing arms 6 on the two lamp holders 7 are close to each other, and the ends of the swing arms 6 on the two lamp holders 7 overlap.

[0026] An explosion-proof lamp 1 is installed on each lamp holder 7. To adapt to the shape of the explosion-proof lamp 1, the upper surface of the L-shaped plate 71 is an arc-shaped concave surface, which can fit the shape of the explosion-proof lamp 1. The lamp holder 7 can effectively support the explosion-proof lamp 1.

[0027] The control unit is used to control the movement of the lamp holder body to change the illumination direction of the explosion-proof lamp 1. The control unit includes a drive component 9 for driving the bogie 4 to rotate in a circular motion, a telescopic component 10 for driving the upper support 5 to tilt in a pitching motion, and a telescopic component 21 for synchronously driving the lamp holders 7 on both sides to rotate in a circular motion. Here, the drive component 9 can be either a motor or a rotary cylinder, and both the telescopic component 10 and the telescopic component 211 are either electric actuators or hydraulic cylinders.

[0028] During installation, the drive component 9 is installed at the lower end of the rotating sleeve 32. The output shaft of the drive component 9 extends into the rotating sleeve 32 and is connected to the rotating shaft 42 of the bogie 4. After installation, the drive component 9 and the fixed bracket 2 are arranged side by side. After the drive component 9 is in operation, it can drive the bogie 4 to rotate in a circumferential direction, and can adjust the circumferential illumination direction of the two explosion-proof lights 1 as a whole.

[0029] During installation, the telescopic component 10 has inner holes 12 on the lower sides of both sides of the U-shaped plate 41 and arc-shaped swing grooves 17 on the upper side. A mounting plate 43 is horizontally installed at one end of the U-shaped plate 41. The mounting plate 43 includes a plate body and reinforcing plates arranged on both sides of the plate body to improve the connection strength between the mounting plate 43 and the U-shaped plate 41. Meanwhile, the inverted U-shaped plate 51 has outer holes 13 on the lower sides of both sides and fixing holes 16 on the upper side.

[0030] Two pitch shafts 14 are installed between the corresponding inner holes 12 and outer holes 13 on the bogie 4 and the upper support 5. The pitch shafts 14 are bolted. A swing shaft 15 is installed between the swing groove 17 and the fixing hole 16 between the bogie 4 and the upper support 5. That is, the swing shaft 15 passes through the two fixing holes 16 and the swing groove 17 laterally, and the two ends of the swing shaft 15 are threaded with nuts to prevent the swing shaft 15 from falling off.

[0031] A telescopic component 10 is hinged between the swing shaft 15 and the mounting plate 43. The telescopic component 10 is arranged at an angle. After the telescopic component 10 is in operation, the upper support 5 swings about the pitch shaft 14 as the center and along the trajectory of the swing groove 17, which can adjust the pitch illumination direction of the two explosion-proof lights 1 as a whole.

[0032] During installation, the telescopic component 2 11 is mounted on the upper bracket 5 and horizontally positioned on the upper fixed plate 52. The end of the telescopic component 2 11 and the end of the two swing arms 6 that coincide are hinged at a single point. Figure 5As shown. After the telescopic component 2 11 is in operation, it can simultaneously drive the two swing arms 6 to move, thereby causing the lamp holder 7 to swing, which can adjust the relative angle between the two explosion-proof lamps 1, that is, adjust the illumination direction of the explosion-proof lamp 1 individually.

[0033] Driven by the control unit, the main body of the lamp holder of this utility model can flexibly adjust the illumination direction of the explosion-proof lamp 1 installed on it. It is easy to operate and can achieve the expected effect. It realizes the vertical and horizontal adjustment of the illumination direction of the explosion-proof lamp 1, solves practical problems, and enables the shotcrete robot to clearly observe the detailed condition of the nozzle and the sprayed surface, as well as the concrete wall condition of the sprayed surface, during shotcrete operation at any angle. It can adjust the shotcrete volume, the required air volume, and the slump adjustment in a timely manner, improve the shotcrete quality, reduce shotcrete rebound, and generate economic benefits.
