The evacuation plate 119 is fixedly connected to the canopy 117. The guide plate 118 is fixedly connected to the canopy 117. The canopy 117 is fixedly connected to the shock absorption assembly 108. The canopy 117, supported by the corresponding shock absorption sleeve 113 and the spring 114, can absorb and buffer falling objects, thus protecting the driver. It can also change the relative distance between the movable frame 104 and the positioning frame 105 by direct pulling, thereby adapting to the needs of different forklifts. This design is convenient to operate, has good protection, and solves the problem that when an object falls above the overhead guard, it can easily pass through the gap and fall into the cab, causing injury to the driver and resulting in low safety.

[0022] The protective canopy 110 is located above the two shock-absorbing components 108, the warning component 109 is located on one side of the movable frame 104, both shock-absorbing components 108 are located above the positioning frame 105, both moving components 107 are located above the movable frame 104, both insert rods 106 are located inside the positioning frame 105, the positioning frame 105 is located on the side of the movable frame 104 away from the warning component 109, the movable frame 104 is located above the straight protective top 101, and the canopy body 117 is made of hard iron sheet material, which has good shock resistance. With the cooperation of the shock-absorbing sleeve 113 and the corresponding spring 114, it effectively mitigates the adverse effects of falling objects colliding with each other.

[0023] Secondly, the limiting wheel 112 is located at the upper end of the upright 111, and the lower end of the upright 111 is located above the movable frame 104. The two ends of the spring 114 are respectively located on the inner walls of the corresponding shock-absorbing sleeves 113. One shock-absorbing sleeve 113 is located above the positioning frame 105, and the other shock-absorbing sleeve 113 is located below the protective canopy 110. Multiple connecting plates are provided on the inner sides of both the positioning frame 105 and the movable frame 104. These connecting plates connect the shock-absorbing sleeves 113 and the upright 111. The installation provides support, and the lower side of the canopy 117 has a groove for the two limiting wheels 112 to slide. The side of the limiting wheel 112 fits against the inner side of the groove. The groove is wide enough not to affect the sliding of the limiting wheel 112. When adjusting the distance between the movable frame 104 and the positioning frame 105, the operator can do so by simply sliding and pulling. Then, the lower ends of the straight protective top 101 and the inclined protective top 102 are installed and fixed to maintain the stability between the movable frame 104 and the positioning frame 105.

[0024] Meanwhile, both work lights 116 are located on one side of the warning plate 115, and the other side of the warning plate 115 is located on one side of the movable frame 104. The evacuation plate 119 is located on one side of the canopy 117, and the guide plate 118 is located on the other side of the canopy 117. The canopy 117 is located above the shock absorption assembly 108. The straight protective top 101 and the inclined protective top 102 can both be adjusted in length using their own bolts, thereby adjusting the height of the movable frame 104 and the positioning frame 105. The movable frame 104 and the positioning frame 105 are connected by two insert rods 106, and the outer ends of the insert rods 106 will not detach from the movable frame 104. Therefore, the movable frame 104 and the positioning frame 105... With a maximum limit of tension, the length of the insert rod 106 can be adjusted during actual use to change the flat area of ​​the movable frame 104 and the positioning frame 105. During use, the device is mainly protected by the canopy 117. When an object falls from above the canopy 117, the shock-absorbing sleeve 113 below the canopy 117 moves downward, causing the spring 114 to deform. The damping of the spring 114 can quickly reset the spring 114, restoring the height of the canopy 117. The fallen object then falls from the sides of the canopy 117 or the evacuation plate 119. The guide plate 118 prevents falling objects from the direction of the inclined top 102 to the front of the cab, protecting the driver and the forklift's working area.

[0025] In this embodiment, the canopy 117 is cast from a hard iron sheet material, providing good shock resistance. With the cooperation of the shock-absorbing sleeve 113 and the corresponding spring 114, it effectively mitigates the adverse effects of falling objects colliding with the object. Multiple connecting plates are provided on the inner sides of both the positioning frame 105 and the movable frame 104. These connecting plates provide support for the installation of the shock-absorbing sleeve 113 and the upright 111. The lower side of the canopy 117 has grooves for the sliding of two limiting wheels 112. The sides of the limiting wheels 112 are flush with the grooves. The inner side of the groove fits snugly, and the width of the groove is sufficient to not affect the sliding of the limiting wheel 112. When adjusting the distance between the movable frame 104 and the positioning frame 105, the operator can do so simply by sliding and pulling. Then, by fixing the lower ends of the straight protective top 101 and the inclined protective top 102, stability between the movable frame 104 and the positioning frame 105 can be maintained. The lengths of both the straight protective top 101 and the inclined protective top 102 can be adjusted using their own bolts, thereby ensuring the stability of the movable frame 104 and the positioning frame 105. The height of the positioning frame 105 is adjustable. The movable frame 104 and the positioning frame 105 are connected by two insert rods 106, allowing for length adjustment. The outer ends of the insert rods 106 do not detach from the movable frame 104, thus maximizing the stretch of the movable frame 104 and the positioning frame 105. In actual use, the length of the insert rods 106 can be adjusted to change the flat area of ​​the movable frame 104 and the positioning frame 105. During use, the equipment is primarily protected by the canopy 117. When an object falls from above the canopy 117, the shock-absorbing sleeve 113 below the canopy 117 moves downward, causing the spring 114 to deform. The damping provided by the spring 114 can quickly reset the spring 114, restoring the height of the canopy 117. The fallen object then falls from either side of the canopy 117 or from the evacuation plate 119. The guide plate 118 prevents the falling object from the direction of the inclined roof 102 to the front of the cab, protecting the driver and the forklift's working area.
