DETAILED DESCRIPTION

[0018] The present invention is further described below in conjunction with the accompanying drawings and examples. In the following detailed description, only certain exemplary embodiments of the present invention are described by way of illustration. Needless to say, those skilled in the art will recognize that the described embodiments may be modified in various ways without departing from the spirit and scope of the present invention. Therefore, the drawings and descriptions are illustrative in nature and are not intended to limit the scope of protection of the claims.

[0019] like Figures 1 to 4 As shown, the cement and clinker bulk operation boarding safety platform is used for workers to easily climb to the roof of the vehicle to carry out bulk operations of cement and clinker, and has stable safety guarantee during the whole operation process, thereby improving the safety of high-altitude operations and helping to improve work efficiency. It specifically includes at least one safety platform unit fixed on the ground, and the workers can transfer from the ground to the roof of the vehicle through the safety platform unit to carry out operations such as bulk loading and cleaning of cement and clinker.

[0020] The safety platform unit of this embodiment includes a platform support frame 1, and a horizontally arranged boarding platform 2 is fixedly installed on the top of the platform support frame 1. The platform support frame 1 can be partially buried below the ground surface to improve its supporting strength. The platform support frame 1 is mainly used to raise the boarding platform 2 so that the boarding platform 2 is higher than the tank truck, and is used to support the staff so that they can be smoothly transferred to the top of the tank truck. A platform top plate 3 is correspondingly provided above the boarding platform 2. The platform top plate 3 is fixedly connected to the corresponding platform support frame 1 and the boarding platform 2. The platform top plate 3 is mainly used to shade the boarding platform 2 from the sun and rain. In order to improve its stability, various support beams can be provided in the platform top plate 3, on the upper part of the platform support frame 1, etc.

[0021] Safety fences 4 are arranged and installed on both sides of the platform support frame 1, on both sides of the boarding platform 2, and on the side of the boarding platform 2 away from the platform support frame 1. The platform support frame 1 is constructed of at least four vertical beams and a number of horizontal beams arranged and connected between adjacent vertical beams, and all of them are steel structures, solid and firm. The distance between the vertical beams is large, and the surrounding side of the boarding platform 2 is an open structure. Therefore, by reasonably arranging the safety fences 4, a large distance is enclosed to form a barrier to ensure the safety of the staff on the boarding platform 2. A climbing ladder 5 is also fixed between the platform support frame 1 and the ground, and the staff can go up and down the boarding platform 2 through the climbing ladder 5. In fact, the safety fences 4 are also arranged on both sides of the climbing ladder 5, which is convenient and safe to use.

[0022] The side of the boarding platform 2 is rotatably mounted with a boarding ladder 6, and the safety fence 4 is provided with an entrance and exit for the staff to go up and down the boarding ladder 6. A ladder lifting device is connected to the boarding ladder 6, and the state of the boarding ladder 6 can be changed by the ladder lifting device. For example, when in use, the boarding ladder 6 is in a vertical state so that the staff can transfer back and forth between the roof of the vehicle and the boarding platform 2 through the boarding ladder 6; after use, the boarding ladder 6 is rotated toward the boarding platform 2 by pulling the ladder lifting device, so that it is in a horizontal state as much as possible to avoid the vehicle and facilitate the safe departure of the vehicle. The working position of the vehicle is provided with the lowering of the boarding ladder 6, so it is necessary to retract and release the boarding ladder 6 to facilitate the entry and departure of the vehicle, which helps to reduce the construction height of the boarding platform 2.

[0023] This embodiment also includes an operating safety rope 7 fixedly connected to the boarding platform 2 or the safety fence 4 on the boarding platform 2, and the other end of the operating safety rope 7 is fixedly set high so that the operating safety rope 7 is in a horizontal state. The operating safety rope 7 is preferably an oil wire rope, which has high strength and is safe to use. A safety belt hook device is provided on the operating safety rope 7. When in use, the waist safety belt of the worker is hooked on the safety belt hook device, and the safety belt hook device can move back and forth along the operating safety rope 7 under the pulling of the waist safety belt to adapt to the change of position of the worker when working on the roof.

[0024] In this embodiment, there are two safety platform units, and the two safety platform units are arranged opposite to each other. The boarding ladder 6 is arranged opposite to each other on the two safety platform units, and the operating safety rope 7 is fixed between the safety fences 4 of the two safety platform units. Multiple workers can board the roof in two directions at the same time to perform operations, which is efficient and easy to use.

[0025] The suspension ladder lifting device includes a winch 8 fixedly mounted on the platform support frame 1 or the platform top plate 3 and a controller 9 for controlling the winch 8. The wire rope 10 of the winch 8 is connected to the bottom end of the boarding suspension ladder 6. The controller 9 is generally used to control the start and stop and forward and reverse rotation of the winch 8. When the winch 8 releases the wire rope 10, the boarding suspension ladder 6 will automatically rotate downward under the gravity of the boarding suspension ladder 6 until it is in a vertical state. The winch 8 is controlled to stop by the controller 9. At this time, the staff can transfer to the roof of the vehicle through the boarding suspension ladder 6; when the work is completed, the staff returns to the boarding platform 2 through the boarding suspension ladder 6. At this time, the winch 8 is controlled by the controller 9 to reverse and reel in the wire rope 10, and at the same time, the boarding suspension ladder 6 is pulled upward to reduce its overall height, so that the vehicle below can smoothly drive away. The control is simple, practical and convenient.

[0026] The bottom end of the platform top plate 3 is equipped with a steering roller 11 used in conjunction with the steel wire rope 10, and the side of the boarding platform 2 is equipped with an anti-friction limiter for limiting the direction of the steel wire rope 10. The steel wire rope 10 passes through the anti-friction limiter and is connected to the boarding ladder 6. Through the coordination of the steering roller 11 and the anti-friction limiter, the steel wire rope 10 is arranged and limited, so that it is relatively regular as a whole, and the conveying steel wire rope 10 is prevented from falling randomly, thereby avoiding the phenomenon of hooking with the vehicle. Specifically, the anti-friction limiter includes two anti-friction rollers 12 installed relatively to each other, and the steel wire rope 10 is arranged between the two anti-friction rollers 12. When the steel wire rope 10 is retracted and released, rolling contact is formed between the steering roller 11 and the anti-friction roller 12, thereby avoiding the wear of the steel wire rope 10 and helping to protect it.

[0027] The safety belt hooking device of this embodiment includes two safety hooks 13 arranged opposite to each other in the upper and lower parts, and a safety pull rope 14 is connected between the two safety hooks 13. The upper safety hook 13 is detachably arranged on the working safety rope 7 and can be separated from the safety hook 13, and the lower safety hook 13 is used to hook the waist safety belt of the staff. After the staff board the boarding platform 2, they first hook the waist safety belt on the lower safety hook 13, and then lower the boarding ladder 6.

[0028] The description of the present invention is given for the purpose of illustration and description, and is not intended to be exhaustive or to limit the present invention to the disclosed form. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present invention and to enable those of ordinary skill in the art to understand the present invention and design various embodiments with various modifications suitable for specific uses.
