Description

Technical Field

[0001] This utility model relates to the field of gypsum board production technology, specifically to a gypsum board distribution bridge fan-shaped safety protection device. Background Technology

[0002] In the gypsum board production workshop, the distribution bridge plays a crucial role, responsible for smoothly conveying the gypsum boards into the dryer. This process not only ensures the integrity and stability of the gypsum boards during transportation but also plays a key role in improving product quality. The distribution bridge mainly consists of a support mechanism, a conveying mechanism, and a drive mechanism. Through multiple sets of conveying mechanisms, each layer of gypsum board is conveyed sequentially into the dryer. During the gypsum board transportation process, to ensure safety, it is strictly forbidden for workers to walk through the sides. Therefore, protective mechanisms are added on both sides to serve as warnings and for protection.

[0003] The current dryer is designed with a multi-layer structure, with different inlet heights for each layer. To achieve comprehensive protection, the designers installed guardrails on both sides of the distribution bridge. These guardrails are approximately 1.5 meters high, which meets basic protection requirements. However, in practical applications, this height also creates blind spots, affecting the monitoring of the entire conveying process. In case of problems, employees may not be able to immediately detect abnormalities. In addition, the guardrails on both sides are installed independently, and they are prone to shaking, tilting, or even collapsing when subjected to external impacts, which would cause the protective function to be lost. Utility Model Content

[0004] Therefore, this utility model provides a gypsum board distribution bridge fan-shaped safety protection device to solve the problems of existing guardrails having blind spots during protection and insufficient stability of the guardrails themselves.

[0005] To achieve the above objectives, the embodiments of this utility model provide the following technical solutions:

[0006] A gypsum board distribution bridge fan-shaped safety protection device includes a protection mechanism and an assembly mechanism. The protection mechanism is provided in two sets, and a conveyor chain body is provided between the two sets of protection mechanisms.

[0007] The protective mechanism includes a fixed mesh cover and a movable mesh cover. Three movable mesh covers are stacked sequentially on the back of the fixed mesh cover. Sliding rods are welded to the back of each movable mesh cover. A shaft passes through one end of each of the fixed and movable mesh covers. The other end of each movable mesh cover opens in a fan shape with the shaft's axis as its center. A slider is slidably connected to the end of each sliding rod. A fixed frame is slidably connected to the outer surface of the slider, and a lead screw is threaded into the inside of the slider. The output shaft of a motor is installed at the bottom of the lead screw, and fixed rods are rotatably connected to both ends of the shaft.

[0008] As a preferred embodiment of this utility model, the assembly mechanism includes a gear, with racks meshing on both sides of the gear, a base plate rotatably connected to the lower surface of the gear, and two slide rails provided on the upper surface of the base plate, with the racks forming a sliding connection with the base plate through the slide rails.

[0009] As a preferred embodiment of this utility model, the assembly mechanism is provided in two sets, and the two sets of assembly mechanisms are respectively located at both ends of the protective mechanism, and the two sets of protective mechanisms are connected by the assembly mechanisms at both ends to form a detachable movable connection.

[0010] In a preferred embodiment of this utility model, the slider is provided with a slot, the slide rod is inserted into the slider through the slot, and the slider slides vertically up and down along the inner wall of the fixing frame via a lead screw.

[0011] As a preferred embodiment of this utility model, the central axis of the fixed mesh cover is parallel to the conveyor chain body, and the fixed mesh cover and the fixed frame are connected by an insertion method, while the central axis of the movable mesh cover is inclined relative to the conveyor chain body.

[0012] As a preferred embodiment of this utility model, both the bottom of the fixing rod and the fixing frame are equipped with auxiliary wheels, and the fixing rod and the fixing frame slide along the upper surface of the bottom plate at both ends respectively through the auxiliary wheels.

[0013] The embodiments of this utility model have the following advantages:

[0014] In this invention, two sets of adjustable-height protective mechanisms are set on both sides of the conveyor chain body. Three movable net covers and fixed net covers form a fan-shaped protective barrier that increases in height. This creates a multi-layered three-dimensional protective structure at different heights, gradually increasing the level of protection. It achieves physical isolation while reducing blind spots, facilitating comprehensive observation by staff and timely monitoring of risks. Furthermore, the protective mechanisms on both sides can be assembled and spliced. The spliced ​​structural design improves the overall impact resistance when subjected to external impacts, better ensuring the safety of personnel and equipment. Attached Figure Description

Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0027] like Figure 1 As shown, the present invention provides a gypsum board distribution bridge fan-shaped safety protection device, including a protection mechanism 1 and an assembly mechanism 2. The protection mechanism 1 is provided in two sets, and a conveyor chain body 3 is provided between the two sets of protection mechanisms 1.

[0028] The protective mechanism 1 includes a fixed mesh cover 101 and a movable mesh cover 102. There are three movable mesh covers 102, which are stacked on the back of the fixed mesh cover 101. Slide rods 103 are welded to the back of the movable mesh covers 102 respectively. A shaft 104 passes through one end of the fixed mesh cover 101 and the movable mesh cover 102. The other end of the movable mesh cover 102 opens in a fan shape with the axis of the shaft 104 as the center. A slider 105 is slidably connected to the end of the slide rod 103. A fixed frame 106 is slidably connected to the outer surface of the slider 105. A lead screw 107 is threaded inside the slider 105. The output shaft of the motor 108 is installed at the bottom of the lead screw 107. Fixed rods 109 are rotatably connected to both ends of the shaft 104.

[0029] In use, the motor 108 is started first, which drives the lead screw 107 to rotate. The three sliders 105, which are threaded to the lead screw 107, slide up and down. The three sliding rods 103 are moved up and down, and the three movable mesh covers 102 are limited by the shaft 104. The other side unfolds into a fan shape with the axis of the shaft 104 as the center, protecting the gypsum board on the surface of the conveyor chain body 3 in the middle. The height of the sliders 105 is adjustable, and the unfolding angle of the fan shape can be adjusted according to the height of the gypsum board layer assembled on the surface of the conveyor chain body 3, so as to maintain the existing viewing angle while protecting the surface and facilitate comprehensive observation.

[0030] like Figure 4As shown, the assembly mechanism 2 includes a gear 201, with racks 202 meshing on both sides of the gear 201. A base plate 203 is rotatably connected to the lower surface of the gear 201. Two slides are provided on the upper surface of the base plate 203, and the racks 202 are slidably connected to the base plate 203 through the slides. The slides limit the sliding of the racks 202 to prevent them from disengaging from the gear 201. The racks 202 on both sides mesh with the gear 201 to achieve synchronous reverse transmission. When assembling the protective mechanism 1, when one side of the protective mechanism 1 moves closer to the middle, the other side of the protective mechanism 1 moves closer to the middle synchronously, ensuring that the gap between the protective mechanisms 1 on both sides and the conveyor chain body 3 remains consistent.

[0031] like Figure 2 and Figure 4 As shown, the assembly mechanism 2 has two sets, and the two sets of assembly mechanisms 2 are respectively located at both ends of the protective mechanism 1. The two sets of protective mechanisms 1 are connected by the assembly mechanisms 2 at both ends to form a detachable movable connection. By setting the two sets of assembly mechanisms 2 at both ends of the protective mechanism 1 and installing them simultaneously, the self-locking mechanism of gear 201 and rack 202 is used to make the two sets of protective mechanisms 1 and assembly mechanisms 2 form a stable quadrilateral structure. When one side of the protective mechanism 1 is impacted, the other side of the protective mechanism 1 can maintain the stability of the overall structure and is not easy to tip over, thereby more effectively ensuring the safety of personnel and equipment.

[0032] like Figure 5 As shown, the slider 105 has a slot, and the slider rod 103 is inserted into the slider 105 through the slot. The slider 105 slides vertically up and down along the inner wall of the fixing frame 106 via the lead screw 107. The function of the fixing frame 106 is to restrict the sliding movement of the slider 105 and ensure its vertical movement. Since the rotation center of one side of the movable mesh cover 102 is fixed, the slider rod 103 will shift in the horizontal direction when the movable mesh cover 102 is unfolded. The slot of the slider 105 provides the necessary space when the slider rod 103 slides.

[0033] like Figure 3 As shown, the central axis of the fixed mesh cover 101 is parallel to the conveyor chain body 3, and the fixed mesh cover 101 and the fixed frame 106 are connected by a plug-in method. The central axis of the movable mesh cover 102 is inclined relative to the conveyor chain body 3. When the lead screw 107 rotates, the fixed mesh cover 101 remains stationary and always remains horizontal with the conveyor chain body 3 to protect the bottom layer of gypsum board during the conveying process. The three movable mesh covers 102 on the back of the fixed mesh cover 101 open in a fan shape, and the inclination angle relative to the conveyor chain body 3 increases sequentially to form a fan-shaped protective railing with progressively increasing height. This can form a multi-layered three-dimensional protective structure at different heights and gradually increase the level of protection.

[0034] like Figure 4As shown, both the bottom of the fixing rod 109 and the fixing frame 106 are equipped with auxiliary wheels. The fixing rod 109 and the fixing frame 106 slide along the upper surface of the bottom plate 203 at both ends through the auxiliary wheels. The auxiliary wheels assist the fixing rod 109 and the fixing frame 106 in sliding along the bottom plate 203, making them smoother and more stable when they move closer to each other or expand outward.

[0035] Although the present invention has been described in detail above with general descriptions and specific embodiments, some modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
