Description

Technical Field

[0001] This utility model relates to the field of laser receiver technology, and in particular to a laser receiver anti-interference device. Background Technology

[0002] Milling and grinding machines are commonly used in road maintenance, airport pavement maintenance, and industrial floor treatment. They are used to precisely remove material layers of a specific thickness, such as asphalt and concrete, to achieve the required flatness, slope, or elevation.

[0003] To achieve this high-precision control, lasers are typically used to assist grinding machines in achieving automatic leveling. Although laser control systems are highly accurate, their precision is affected by the environment. Light travels in a straight line in a vacuum, but when it travels through media such as air, if the media density is uneven, its propagation path will bend. Furthermore, refraction will occur in environments with glass windows, direct sunlight, dust, water mist, and smoke. These factors can also interfere with the receiver's detection of the laser signal, causing the actual milling depth and milled surface to differ from the design value, severely impacting construction quality. Utility Model Content

[0004] The purpose of this invention is to provide a laser receiver anti-interference device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An anti-interference device for a laser receiver includes a fixed rod, a laser receiver, a light shield, a driving device, and an adjusting cover. The laser receiver is sleeved and connected to the fixed rod. The light shield is sleeved and connected to the outer wall of the laser receiver. The light shield has a first light-transmitting hole. The adjusting cover is sleeved at the first light-transmitting hole of the light shield and has a second light-transmitting hole. The driving device is fixed to the light shield and is drivenly connected to the adjusting cover. The second light-transmitting hole is smaller than the first light-transmitting hole. The driving device drives the second light-transmitting hole on the adjusting cover to move across the first light-transmitting hole of the light shield.

[0007] Preferably, a mounting platform is connected to the fixing rod, and the bottom of the laser receiver is located on the mounting platform.

[0008] Preferably, the mounting platform has screw holes, and the mounting platform is fixed to the fixing rod by bolts.

[0009] Preferably, the top of the light shield has a screw hole, the light shield is fixed to the top of the laser receiver by bolts, and a connecting ring is installed at the bottom of the light shield.

[0010] Preferably, the driving device includes a push rod motor and a fixed plate. The bottom of the push rod motor is fixed on the connecting ring of the light shield. The fixed plate includes two side plates and a connecting plate connecting the two side plates. A through groove is provided on the connecting plate. The output end of the push rod motor is connected to the top of the connecting plate through the through groove. The adjusting cover is installed between the two side plates of the fixed plate.

[0011] Preferably, the laser receiver has a screw hole at the bottom, and the laser receiver is fixed to the fixing rod by bolts.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention uses a light shield to cover the laser receiver. The second light-transmitting hole of the adjustable shield is adjusted up and down at the first light-transmitting hole of the light shield. The adjustable shield moves with the laser emitted by the laser emitter, so that the laser always stays in the center position of the second light-transmitting hole of the adjustable shield. This avoids interference from environmental factors to the laser receiver, and the laser receiver can receive signals stably, improving construction efficiency and quality.

[0021] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0022] like Figure 1-5As shown, a laser receiver anti-interference device includes a fixing rod 1, a laser receiver 2, a light shield 3, a driving device, and an adjustment cover 6.

[0023] A mounting platform 11 is slidably connected to the fixed rod 1. The mounting platform 11 is adjustable in height on the fixed rod 1. The mounting platform 11 has screw holes and is fixed to the fixed rod 1 by bolts.

[0024] The laser receiver 2 is mounted on the fixed rod 1. The bottom of the laser receiver 2 is located on the mounting platform 11, which provides support. The bottom of the laser receiver 2 has screw holes, and the laser receiver 2 is fixed to the fixed rod 1 by bolts.

[0025] The light shield 3 is fitted onto the outer wall of the laser receiver 2. The top of the light shield 3 has a screw hole. The light shield 3 is fixed to the top of the laser receiver 2 by bolts. The light shield 3 has a first light-transmitting hole 32.

[0026] An adjusting cover 6 is fitted onto the first light-transmitting hole 32 of the light-shielding cover 3. The adjusting cover 6 has a second light-transmitting hole 61. A driving device is fixed to the light-shielding cover 3 and is connected to the adjusting cover 6 via a transmission mechanism. The driving device includes a push rod motor 4 and a fixing plate 5. A connecting ring 31 is installed at the bottom of the light-shielding cover 3. The bottom of the push rod motor 4 is fixed to the connecting ring 31 of the light-shielding cover 3. The fixing plate 5 includes two side plates and a connecting plate connecting the two side plates. A through groove 51 is provided on the connecting plate. The output end of the push rod motor 4 is connected to the top of the connecting plate via the through groove 51. The adjusting cover 6 is installed between the two side plates of the fixing plate 5. The second light-transmitting hole 61 is smaller than the first light-transmitting hole 32. The push rod motor 4 drives the second light-transmitting hole 61 on the adjusting cover 6 to move on the first light-transmitting hole 32 of the light-shielding cover 3.

[0027] The working principle of this utility model:

[0028] like Figure 5 As shown, the bottom of the fixing rod 1 is installed on the milling and grinding machine 8. The milling and grinding machine 8 is equipped with a PLC controller 7, which is electrically connected to the push rod motor 4 and the laser receiver 2. When the laser receiver 2 detects a slight upward or downward deviation of the laser, it transmits a signal to the controller 7. The controller 7 controls the push rod motor 4 to follow the laser. The output end of the push rod motor 4 drives the fixing plate 5 to move. The fixing plate 5 drives the adjusting cover 6 to move up and down on the light shield 3, so that the second light-transmitting hole 61 moves on the first light-transmitting hole 32, so that the laser is located at the center of the second light-transmitting hole 61. The laser shines on the laser receiver 2 through the second light-transmitting hole 61 and the first light-transmitting hole 32, preventing other parts of the laser receiver 2 from receiving refracted light and avoiding interference from environmental factors.
