[0018] As Figures 1-5The utility model provides a kind of elevator car top overhauling safety protection device, the safety protection device is installed at elevator door 5, including fixing device 1, wearable safety belt 2, safety rope 3, shielding device 4;The fixing device 1 is detachably installed at elevator door 5, wearable safety belt 2 is connected on fixing device 1 by safety rope 3;The shielding device 4 is installed on fixing device 1, and is shielded above car;The fixing device 1 includes two fixed plates 11, connecting rod 12, locking bolt 13;Connecting rod 12 two ends are connected in the middle of two fixed plates 11 respectively, form H-shaped structure, two fixed plates 11 two ends are clamped in the two sides of elevator door 5, and locking bolt 13 is installed in the two ends of fixed plate 11, and rotating bolt is pressed on the wall of elevator door 5 to fix fixing device 1;Wearable safety belt 2 is connected on fixed plate 11 by safety rope 3.The protection device when using, the two fixed plates 11 of fixing device 1 are clamped in the two sides of elevator door 5, then rotating locking bolt 13, so that the end of locking bolt 13 is pressed on the wall of the two sides of elevator door 5, to install and fix fixing device 1, and wearable safety belt 2 is worn on the body of overhauling personnel, then overhauling personnel is carried out on the elevator car top Maintenance work, the utility model is detachably installed in the fixing device 1 at elevator door 5, so that the device is conveniently installed and fixed, and installation efficiency is high, wearable safety belt 2 is worn on the body of overhauling personnel, is connected by safety rope 3, so that the risk of overhauling personnel falling is prevented when car shakes or falls, and the life safety of overhauling personnel is guaranteed;Shielding device 4 is blocked above overhauling personnel, can prevent the object falling on elevator shaft from injuring overhauling personnel.

[0019] The end of locking bolt 13 pressed on wall is provided with rubber pad 131.Rubber pad 131 is padded on wall, can prevent the pressure of locking bolt 13 from damaging wall surface.

[0020] The end of locking bolt 13 is provided with hand wheel 132 for facilitating rotation.Hand wheel 132 can facilitate the rotation of locking bolt 13 to fix fixing device 1.

[0021] The shielding device 4 includes two support rods 41, a folding rod 42, a fixing rod 43, and a shielding cloth 44. The two support rods 41 are respectively threaded onto the mounting blocks 45 at both ends of the fixing plate 11. The two ends of the folding rod 42 are respectively hinged to the rotating rings 46 rotatably mounted on the upper ends of the two support rods 41. The rotating rings 46 allow the support rods 41 to rotate normally when rotatably mounted on the mounting blocks 45, without being restricted by the connection of the folding rods 42. There are two fixing rods 43, which are respectively connected to the rotating rings 46 on the two support rods 41. The shielding cloth 44 is connected to the folding rods 42 and the fixing rods 43. When the shielding device 4 is installed, the two support rods 41 are pulled apart, thereby opening the folding rod 42 and opening the shielding cloth 44. The two support rods 41 are fixed to the mounting block 45 on the fixing plate 11 by screw rotation, thereby fixing the support rods 41. The shielding cloth 44 is placed above the car top and above the maintenance personnel, thereby blocking objects falling from the elevator shaft and preventing them from injuring the maintenance personnel.

[0022] The fixed rod 43 is hinged to the rotating ring 46. An adjusting rod 47 is also connected between the fixed rod 43 and the support rod 41. The two ends of the adjusting rod 47 are respectively hinged to the fixed rod 43 and to the sliding sleeve 48 fitted on the support rod 41. The adjusting rod 47 facilitates the adjustment of the storage of the covering cloth 44. When maintenance personnel are working, after the support rod 41 is installed on the fixing device 1, the fixed rod 43 is raised, the sliding sleeve 48 moves upward, and the adjusting rod 47 pushes the fixed rod 43 to rotate, thus raising the covering cloth 44 so that the covering cloth 44 covers the maintenance personnel. After the maintenance is completed, the sliding sleeve 48 is slid downward to retract the fixed rod 43 and store the covering cloth 44 for easy storage and transportation.

[0023] Preferably, the sliding sleeve 48 is threadedly connected to a locking knob 49 on its side wall. When the sliding sleeve 48 slides to support the fixing rod 43, the position of the sliding sleeve 48 is locked by the locking knob 49, thereby fixing the fixing rod 43 and the shielding cloth 44.

[0024] Work process:

[0025] When using this protective device, the two fixing plates 11 of the fixing device 1 are clamped onto both sides of the elevator door 5. Then, the locking bolts 13 are rotated so that the ends of the locking bolts 13 are pressed against the walls on both sides of the elevator door 5, thereby fixing the fixing device 1 in place. Maintenance personnel wear the wearable safety belt 2 and then carry out maintenance work on the top of the elevator car. When the shielding device 4 is installed, the two support rods 41 are pulled apart, thereby opening the folding rod 42 and opening the shielding cloth 44. The two support rods 41 are fixed to the mounting block 45 on the fixing plate 11 by screw rotation, thereby fixing the support rods 41. The sliding sleeve 48 moves upward, and the adjusting rod 47 pushes the fixing rod 43 to rotate, thus supporting the shielding cloth 44, so that the shielding cloth 44 blocks the maintenance personnel. The position of the sliding sleeve 48 is locked by the locking knob 49. After the maintenance is completed, the sliding sleeve 48 is slid downward, so that the fixing rod 43 is retracted downward, and the shielding cloth 44 is stored. The shielding cloth 44 blocks the top of the car and is located above the maintenance personnel, thereby blocking objects falling from the elevator shaft and preventing them from injuring the maintenance personnel.

[0026] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of this utility model.
