Referring to fig. 1 to 6, an embodiment of the present application provides a semi-automatic rotating type car top guardrail, including:

the guardrail assembly and the servo motor 3 connected with the guardrail assembly through the steel wire rope 8. The guardrail assembly comprises a guardrail base 5 and a guardrail frame 1. The guardrail base 5 is arranged around the top of the car, one end of the guardrail frame 1, which is far away from the guardrail base 5, is provided with a handrail cross rod 11, two ends of the handrail cross rod 11 are fixedly provided with support rods 12, and the support rods 12 are rotationally connected with the guardrail base 5. The servo motor 3 is arranged on the outer side of the guardrail assembly, and a steel wire rope 8 is wound on a rotating shaft of the servo motor 3.

The car roof guardrail has two states of working and non-working, and when the car roof guardrail is in a working state, the guardrail frame 1 is perpendicular to the car roof; when the car roof guardrail is in a non-working state, the guardrail frame 1 is placed on the car roof in an inward rotating mode.

The guard rail assembly may be constructed of metal and includes a guard rail frame 1 and a guard rail base 5. The guardrail frame 1 is composed of the handrail cross bar 11 and supporting rods 12 arranged at two ends of the handrail cross bar 11. The length of the handrail rail 11 of the guardrail frame 1 should be smaller than the width of the car roof. The guardrail frame 1 can be provided with at least one cross rod in parallel with the handrail cross rod 11, and two ends of the cross rod can be fixed on the support rod 12. One end of the support rod 12 of the guardrail frame 1 far away from the handrail cross rod 11 is rotatably connected with the guardrail base 12. One end of the guardrail base 5 is provided with a space for accommodating the rotation of the support rod 12, and the other end of the guardrail base 5 is fixed on the top of the car. The guardrail components can be symmetrically arranged on two sides of the top surface of the car.

Further, a rotation shaft 9 may be provided to penetrate through a connection portion of the support bar 12 and the guardrail base 5, so that the support bar 12 and the guardrail base 5 are rotatably connected. The cotter pin 10 is fixed at both sides of the rotating shaft 9. The cotter pin 10 can prevent the rotation shaft 9 from coming out.

Further, an action switch 2 can be arranged on the guardrail base 5. The action switch 2 can be fixed on the outer side of the upper end of the guardrail base 5 through a bending piece, and the switch contact surface of the action switch 2 faces to the inner side and is vertical to the bottom of the car. The action switch 2 can be connected with the servo motor 3 and can control the servo motor 3 to be turned off.

The servo motor 3 is fixed on the side surface of the car by the bending piece motor bracket 4. The rotating shaft of the servo motor 3 is connected with the guardrail frame 1 through the steel wire rope 8.

The car roof guardrail can be in an operating state or a non-operating state. When the car roof guardrail is in a working state, the servo motor 3 rotates the rotating shaft, so that the steel wire rope 8 is wound on the rotating shaft, and the guardrail frame 1 is driven to rotate outwards. When the guardrail frame 1 rotates to be vertical to the top of the car, the guardrail frame 1 is abutted against the action switch 2. When the car roof guardrail is turned from the working state to the non-working state, the rotating shaft of the servo motor 3 reversely rotates, so that the steel wire rope 8 is separated from the rotating shaft. And thus the fence frame 1 is rotated inwards to be parallel to the car roof, so that the car roof fence is in a non-operating state.

Further, when the car roof rail is in a non-operating state, the handrail cross bar 11 may collide with the reset switch 6 provided on the car roof. The reset switch 6 is fixed on the top of the car through a bending piece switch bracket 7. The reset switch may be symmetrically disposed above the car roof.

Although various specific embodiments are described in this application, the application is not limited to the details of the industry standard or examples, which are intended to indicate that the same, equivalent or similar embodiments or variations as described in the above examples may be achieved by the use of custom or modified embodiments. Examples of ways of data acquisition, processing, output, judgment, etc. using these modifications or variations are still within the scope of alternative embodiments of the present application.

Although the present application has been described by way of example, one of ordinary skill in the art will recognize that there are many variations and modifications to the present application without departing from the spirit of the present application, and it is intended that the appended embodiments include such variations and modifications without departing from the application.
