[0026] Such as Figure 1 , Figure 3 and Figure 4As shown in the figure, an embodiment of the present utility model provides an elevator car top that is convenient for maintenance and repair, including: an elevator body 1 and a car top body 2; a groove 201 is opened at the top of the car top body 2, a maintenance opening 202 is opened at the bottom of the inner wall of the groove 201, and a maintenance cover 203 is rotatably connected to the inner wall of the groove 201; a circular groove 204 is opened on the inner wall of the groove 201, a spring 205 that provides elastic force is fixedly assembled on the inner wall of the circular groove 204, a connecting block 206 is fixedly assembled at one end of the spring 205 away from the circular groove 204, a clamping block 207 is fixedly assembled on one side of the connecting block 206 away from the spring 205, and the outer wall of the clamping block 207 is clamped with the maintenance cover 203; a rotating shaft 208 is rotatably connected to the top of the car top body 2, a connecting rope 209 is fixedly assembled on one side of the connecting block 206 close to the spring 205, one end of the connecting rope 209 away from the connecting block 206 is fixedly connected to the rotating shaft 208, and knobs 210 are fixedly assembled at both ends of the rotating shaft 208. The number of the springs 205, the connecting blocks 206 and the clamping blocks 207 is two groups, and the two groups of springs 205, the connecting blocks 206 and the clamping blocks 207 are symmetrically distributed on both sides of the rotating shaft 208. By limiting the number and position of the springs 205, the connecting blocks 206 and the clamping blocks 207, it is beneficial to improve the firmness and stability of the fixation of the maintenance cover 203.

[0027] As Figure 1 and Figure 3 shown, a guardrail 211 is fixedly assembled on the top of the car top body 2. By setting the guardrail 211, it is convenient for maintenance personnel to identify the boundary of the car, prevent the feet from stepping on the air, and improve the safety of the device.

[0028] As Figure 3 shown, handles 212 are fixedly assembled on the outer wall of the maintenance cover 203. The number of the handles 212 is two, and the two handles 212 are symmetrically distributed at the upper and lower ends of the maintenance cover 203. By setting the handles 212, it is beneficial to open and close the maintenance cover 203 through the handles 212.

[0029] As Figure 2 and Figure 5 shown, a fixing groove 213 is opened on the inner wall of the groove 201, an infrared sensor 214 is fixedly assembled on the inner wall of the fixing groove 213, an LED lamp 215 is fixedly assembled on the top of the car top body 2, and the infrared sensor 214 is electrically connected to the LED lamp 215. By setting the infrared sensor 214, it is beneficial to control the switch of the LED lamp 215 by the infrared sensor 214 when a person passes through the maintenance opening 202, so as to facilitate the lighting when maintenance personnel repair the elevator auxiliary equipment on the top of the car, without the need to bring their own light source.

By providing the round hole 216 in the inspection cover 203 and arranging the exhaust fan 217, it is beneficial to ensure the air circulation in the elevator body 1 when the device is in use.

[0031] In the technical solution provided by the present utility model, during operation, by providing the inspection cover 203, it is beneficial for maintenance personnel to enter the top of the car from the inspection opening 202. Only by rotating the knob 210, the connecting rope 209 is wound around the outer wall of the rotating shaft 208 through the rotation of the knob 210, thereby pulling the connecting block 206 and the clamping block 207 to move deeper into the round groove 204, separating the clamping block 207 from the inspection cover 203, and then the inspection cover 203 can be easily opened through the handle 212. When it is necessary to close the inspection cover 203, the inspection cover 203 is rotated into the groove 201. When the clamping block 207 is squeezed by the inspection cover 203 and moves deeper into the round groove 204, after the inspection cover 203 is completely embedded in the groove 201, the clamping block 207 loses the extrusion, and the connecting block 206 and the clamping block 207 are pushed towards the inspection cover 203 by the spring 205 until they are clamped with the inspection cover 203.

[0032] By providing the round hole 216 in the inspection cover 203 and arranging the exhaust fan 217, it is beneficial to ensure the air circulation in the elevator body 1 when the device is in use.

[0033] By providing the infrared sensor 214, it is beneficial that when a person passes through the inspection opening 202, the infrared sensor 214 controls the switch of the LED lamp 215, thereby facilitating the lighting for maintenance personnel to repair the elevator auxiliary equipment at the top of the car without the need to bring their own light source.

[0034] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present utility model, several improvements and refinements can still be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model.
