Description

Technical Field

[0001] The present invention relates to the technical field of building construction protection, in particular to a laser rangefinder anti-collision protection device and a protection method thereof used in a cross construction hoisting operation of a glass curtain wall. Background Art

[0002] A laser rangefinder is an instrument that uses a certain parameter of a modulated laser to accurately measure the distance to a target. During the construction of glass curtain walls, cross-construction is required due to factors such as construction period. Since glass curtain wall construction generally involves high-altitude operations, a laser rangefinder is needed to measure the distance between hoisting baskets to prevent accidents due to collisions during cross-construction. However, laser rangefinders installed on hoisting baskets are prone to accidental collisions during construction, causing damage to the laser rangefinder. Although existing laser rangefinder protective devices can provide a certain degree of protection for laser rangefinders, when objects approach quickly, the laser rangefinder lens is still close to the opening, and the lens is easily damaged when it is hit.

[0003] A Chinese patent application with an application date of September 12, 2023, and publication number CN220855190U discloses a protective device for a laser rangefinder, comprising a housing and a cover. The cover is detachably connected to the housing. A fixing bracket is disposed within the housing, located on a side wall of the housing away from the cover. The fixing bracket is movably connected to a first laser rangefinder. The cover is provided with an opening corresponding to the position of the first laser rangefinder. The side of the cover facing the housing is connected to a drive device electrically connected to the first laser rangefinder. A cover plate is disposed over the opening, and the drive device drives the cover plate to open and close the opening according to the operating state of the first laser rangefinder. By providing the housing, cover, and cover plate, the laser rangefinder is not exposed to the external environment. By providing the drive device and electrically connecting the drive device to the laser rangefinder, the cover plate is driven to open and close autonomously in accordance with the operating state of the laser rangefinder.

[0004] Since the cover body is provided with an opening, although the cover plate blocks the opening, when the opening is hit and the cover plate breaks, the laser rangefinder is close to the opening and the flying debris may damage the lens of the laser rangefinder. Therefore, further improvements can be made. Summary of the Invention

The driving assembly 900 drives the sealing assembly 800 to seal the monitoring port 200 and drives the clamping assembly 600 to slide backward along the guide rail 500.

[0034] The mounting base 400 includes an L-shaped base 401 with an L-shaped backing plate 402 welded to its inner surface. The L-shaped backing plate 402 is fixedly mounted to the bottom and rear side of the protective box 100. Mounting holes 403 are defined through both the horizontal and vertical portions of the L-shaped base 401. During installation, the L-shaped base 401 can be mounted to the hanging basket using screws inserted through the mounting holes 403. Either the bottom or rear surface of the L-shaped base 401 can serve as a mounting surface, making installation more flexible.

[0035] The clamping assembly 600 includes a holding bucket 601, and a slider 602 is fixedly installed at the bottom of the holding bucket 601. The slider 602 is slidably connected to the top of the guide rail 500. The cross-section of the slider 602 is in a "convex" shape. A linear slide groove is provided on the top of the guide rail 500. The opening of the linear groove is adapted to the cross-section of the slider 602. The slider 602 is slidably connected in the linear slide groove.

[0036] A rear baffle 603 is fixedly mounted on the top rear end of the container 601. The lower half of the rangefinder body 700 is inserted into the container 601, and the rear baffle 603 fits against the rear side of the rangefinder body 700. Thus, the container 601 and rear baffle 603 enclose the lower half of the rangefinder body 700 and limit the rangefinder body 700 in the front-to-back direction.

[0037] The upper half of the rangefinder body 700 is covered with an arched plate 604. A front baffle 605 is fixedly mounted to the front of the arched plate 604, which fits against the front side of the rangefinder body 700. Lugs 609 are fixedly mounted to the rear end of the top of the rear baffle 603 and the rear end of the arched plate 604. Bolts 610 are connected between the two lugs 609. Thus, the arched plate 604 covers the upper half of the rangefinder body 700, and the bolts 610 and lugs 609 initially connect the container 601 to the arched plate 604. A longitudinal stopper is provided between the container 601 and the arched plate 604.

[0038] The longitudinal limiter includes two brackets 607 fixedly installed on the left and right sides of the containing bucket 601, and a sliding column 608 is fixedly installed on the opposite side of the top of the two brackets 607.

As the arched plate 604 moves downward, the slide post 1 608 slides along the vertical portion of the L-shaped groove 606. When the top wall of the arched plate 604 is in contact with the top of the rangefinder body 700, the arched plate 604 is pushed backward so that the slide post 1 608 slides along the horizontal portion of the L-shaped groove 606 until the front baffle 605 is in contact with the front side of the rangefinder body 700. At this time, the two lugs 609 are aligned.

[0039] The sealing assembly 800 comprises an annular seat 801 fixedly mounted on the front inner wall of the protective box 100. The center of the annular seat 801 is connected to the monitoring port 200. A plurality of slide slots 802 are arranged in an array on the rear side of the annular seat 801. In this embodiment, there are four slide slots 802. A plurality of clamping plates 803 are fixed in an array on the rear edge of the annular seat 801. The clamping plates 803 are generally arc-shaped with an L-shaped cross-section. A sealing plate 804 is slidably connected within the slide slots 802. A second sliding post 805 is fixedly mounted to the rear side of the sealing plate 804. A swivel 806 is rotatably connected between the clamping plates 803, which adhere to the circumference and rear side of the swivel 806. An array of inclined grooves 807 are formed throughout the upper portion of the swivel 806. The second slide posts 805 correspond one-to-one with the inclined grooves 807. The second slide posts 805 are slidably connected within the inclined grooves 807. As the swivel 806 rotates, the swivel 806, located on the inner wall of the inclined grooves 807, squeezes the second slide posts 805, driving the sealing plate 804 to slide along the slide grooves 802, sealing and opening the center of the annular seat 801. An array of bosses 808 are fixed to the rear edge of the swivel 806.

[0040] The drive assembly 900 includes a motor 901 fixedly mounted on the inner wall of the rear side of the protective box 100. The model of the motor 901 is CCW15. The motor 901 is signal-connected to the rangefinder body 700. The motor 901 and the rangefinder body 700 are signal-connected to a controller. When an object rapidly approaches the monitoring port 200, the rangefinder body 700 receives the signal and transmits the signal to the controller, which controls the motor 901 to start. A threaded rod 902 is fixedly mounted on the output end of the motor 901. A cross arm 903 is threadedly connected to the threaded rod 902. A threaded hole is provided on the cross arm 903. The cross arm 903 is fixedly mounted on the side of the containing bucket 601. A drive gear 904 is fixedly mounted on the front end of the threaded rod 902. The drive gear 904 is meshed with a ring gear 905. The ring gear 905 is fixedly mounted on the rear side of the boss 808. Motor 901 drives threaded rod 902 to rotate, driving cross arm 903 and clamping assembly 600 to move along monitoring port 200. Threaded rod 902 also drives drive gear 904 to rotate, thereby driving ring gear 905 and swivel 806. The controller is equipped with a reset button. After drive assembly 900 drives sealing assembly 800 to seal monitoring port 200, the reset button can be manually pressed to cause drive assembly 900 to drive sealing assembly 800 again, exposing monitoring port 200.

[0041] Example 2: A protection method using the glass curtain wall cross construction hoisting anti-collision laser ranging protection device described in Example 1 includes the following steps: S1. Real-time monitoring of the distance between hanging baskets by using the rangefinder body 700; S2. When an object approaches the monitoring port 200 at a speed greater than a set speed, the rangefinder body 700 transmits a signal to the controller; S3. The controller starts the motor 901, which drives the threaded rod 902 to rotate, driving the cross arm 903 and the clamping assembly 600 to move backward along the guide rail 500, so that the rangefinder body 700 is away from the monitoring port 200. S4, the threaded rod 902 drives the driving gear 904 to rotate, causing the ring gear 905 and the rotating ring 806 to rotate; S5. The inner wall of the rotating ring 806 located at the inclined groove 807 squeezes the sliding column 2 805, driving the sealing plate 804 to slide inward along the sliding groove 802, sealing the center of the annular seat 801 to prevent objects from passing through the monitoring port 200 and hitting the rangefinder body 700.

[0042] Among them: the controller is provided with a reset button. After the driving component 900 drives the sealing component 800 to seal the monitoring port 200, the reset button can be manually pressed to make the driving component 900 drive the sealing component 800 to expose the monitoring port 200 so that the rangefinder body 700 can resume normal operation.

[0043] During use, the distance between the hanging baskets is monitored in real time through the rangefinder body 700. When an object quickly approaches the monitoring port 200, the rangefinder body 700 transmits a signal to the controller, which activates the motor 901. The motor 901 drives the threaded rod 902 to rotate, driving the cross arm 903 and the clamping assembly 600 to move backward along the guide rail 500, so that the rangefinder body 700 is away from the monitoring port 200. At the same time, the threaded rod 902 drives the driving gear 904 to rotate, causing the ring gear 905 and the swivel 806 to rotate. The swivel 806 is located at the inner wall of the inclined groove 807 and squeezes the sliding column 2 805, driving the sealing plate 804 to slide inward along the sliding groove 802, sealing the center of the annular seat 801, and preventing objects from passing through the monitoring port 200 and hitting the rangefinder body 700.
