Description

Technical Field

[0001] The utility model relates to a safety protection device for loading and unloading goods from an open-top freight car installed in an outdoor freight yard, and particularly relates to a loading and unloading protection device with safe use. Background Art

[0002] After cigarette production, it is first sub-packaged into small boxes, which are the cigarette boxes that consumers carry with them. Then, a specified number of boxed cigarettes are packed into a strip-shaped paper box, commonly known as a carton of cigarettes, which mainly facilitates the sellers. Finally, to ensure the quality and safety of the cartons of cigarettes during transportation, the cartons of cigarettes are stacked in cigarette boxes for transportation.

[0003] In the previous business model, the cigarette boxes were only used once and then directly disposed of as waste paper by dealers, etc. With the promotion of various national energy conservation and emission reduction measures, these used cigarette boxes are recycled and transported to the logistics transfer station of the tobacco production department. During the transportation of the cigarette boxes, they need to be loaded and unloaded from the freight car first. When loading and unloading, the staff need to climb onto the roof of the car to assist in loading and unloading. At this time, the staff has the possibility of falling from the car, and protective equipment needs to be provided for the staff to prevent them from falling. Some existing protective equipment has problems such as complex beam structures and inconvenient use. Content of the Utility Model

[0004] The purpose of the utility model is to provide a loading and unloading protection device with safe use to overcome the deficiencies of the prior art.

[0005] The purpose of the utility model is realized as follows: a loading and unloading protection device, characterized in that: it includes two support beams vertically fixed on the loading and unloading site, a horizontal beam extending outward is arranged on the upper part of the support beam, a first fixed pulley is arranged at the outer end of each horizontal beam, a second fixed pulley is fixedly arranged on the outer side surface of the middle upper part of each support beam, and a ground anchor is arranged on the ground outside each support beam; the device also includes a steel wire rope, and both ends of the steel wire rope sequentially pass through the first fixed pulley and the second fixed pulley and are finally fixedly connected to the ground anchor;

[0006] A hanging ring capable of moving along the steel wire rope is sleeved on the steel wire rope between the rod heads of the two horizontal beams, a fall-prevention self-locking device is connected to the hanging ring, and a safety rope is connected to the bottom of the fall-prevention self-locking device.

[0007] Further optimization, a forging flower basket screw wire tightener is arranged on the steel wire rope between the second fixed pulley and the ground anchor, and the included angle between the steel wire rope between the second fixed pulley and the ground anchor and the support beam is not less than 45°.

[0008] For further optimization, a reinforcing beam rod is also provided at the top end of the support beam, an oblique support is provided in the vertical plane between the horizontal beam and the support beam, and a horizontal support is provided in the horizontal plane between the horizontal beam and the reinforcing beam rod.

[0009] Advantages of this utility model:

[0010] The main frame of the device is mainly composed of two support beams, a horizontal beam arranged on the upper part of the support beam and extending outward, and a steel wire rope arranged between the rod heads of the two horizontal beams through the first fixed pulley. The structure is simple and practical. In order to ensure the stability of the above structure, a reinforcing beam rod is also arranged at the top of the support beam, an oblique support is arranged between the horizontal beam and the support beam in the vertical plane, and a horizontal support is arranged between the horizontal beam and the reinforcing beam rod in the horizontal plane, using the stability of the triangle to additionally improve the strength of this part.

[0011] The die-forged flower basket screw tensioner can adjust the tightness of the wire rope. The wire rope is provided with a lifting ring that can move along the wire rope. The outer surface of the wire rope has natural texture, which can provide a certain friction resistance. When the truck is loading and unloading, the truck flatbed is located below the two support beams, and the wire rope runs along the front and rear of the vehicle body. The unloading staff can drag the lifting ring to move the lifting ring along the wire rope, thereby facilitating the loading and unloading operations, and in the width direction of the vehicle body, it can move back and forth within the length of the safety rope. If a staff member falls from the roof, due to the existence of the staff member's own weight, the wire rope will undergo elastic deformation, and the staff member is likely to slide to the middle of the wire rope, and the texture on the surface of the wire rope increases the friction between the lifting ring and the lifting ring. The friction can slow down the moving speed of the lifting ring on the surface of the wire rope, which serves the purpose of fall buffering and increases the safety of the user.

[0012] The first pulley arranged at the outer end of the horizontal beam is used to change the direction of the wire rope and adjust the tightness. The second fixed pulley at two-thirds of the upper end of the support beam is used to change the direction of the wire rope. The wire rope extends downward from there. A ground anchor is arranged in the horizontal direction from the bottom of the support beam, and the wire rope and the ground anchor are connected with a forged flower basket screw tensioner. The angle between the wire rope and the longitudinal support beam is not less than 45% to ensure the load-bearing strength of the wire rope. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of this application.

[0017] Embodiment 1 is as Figures 1 to 3 shown. A loading and unloading protection device includes two support beams 1 vertically fixed on the unloading site. In this embodiment, the material of the support beam 1 is channel steel, so as to provide sufficient bending resistance. A horizontal beam 2 extending outward is provided on the upper part of the support beam 1. The horizontal beam 2 and the support beam 1 are fixedly connected by a plurality of bolts, improving the installation convenience.

[0018] A first fixed pulley 3 is provided at the end of each horizontal beam 2. A sling 5 capable of moving along the axis of the steel wire rope 4 is sleeved on the steel wire rope 4 between the two first fixed pulleys 3. A fall-preventing self-locking device 6 is connected to the sling 5. When the worker moves back and forth on the vehicle body, the rope body in the fall-preventing self-locking device 6 can be freely pulled out. When the worker quickly falls from the vehicle body, the rope body in the fall-preventing self-locking device 6 will be locked, thus preventing the worker from directly touching the ground. The fall-preventing self-locking device 6 is a general product in the prior art, so its structure will not be described in detail here. The fall-preventing self-locking device 6 supporting this solution is produced by Taizhou Tengyu Rope Net Belt Co., Ltd.

[0019] A safety rope 7 is connected to the bottom of the fall-preventing self-locking device 6. A hook is provided at the lower end of the safety rope 7. The worker wears a vest that can be connected to the hook at the lower end of the safety rope. When the worker is on the goods in the carriage, first connect the vest worn on the body to the hook on the safety rope 7. In this embodiment, in order to increase the safety redundancy, the total length of the safety rope used plus the length of the rope inside the fall-preventing self-locking device 6 is less than the length of the straight line distance from the fall-preventing self-locking device 6 to the ground.

[0020] During unloading, the horizontal beam 2 is located above the carriage, and the axis of the horizontal beam 2 is parallel to the running direction of the vehicle body. When the worker accidentally falls, the sling 5 is pulled by the weight of the person and moves horizontally uncontrollably, giving an axial movement of the sling 5 a frictional force on the surface texture of the steel wire rope 4, slowing down the amplitude of the horizontal uncontrollable movement of the sling 5 pulled by the weight of the person. Moreover, due to the elastic deformation of the steel wire rope 4, it is easier for the worker to slide towards the middle position of the rope, and the worker is not likely to have a hard collision with structures such as the support beam 1.

[0021] On the outer side surface of the middle and upper part of each support beam 1, a second fixed pulley 8 is fixedly arranged. On the ground outside each support beam 1, a ground anchor 9 is arranged. The ground anchor 9 and the second fixed pulley 8 are located in the same vertical plane. The two ends of the steel wire rope 4 sequentially pass through the first fixed pulley 3 and the second fixed pulley 8, and finally the two ends of the steel wire rope 4 are fixedly connected to the ground anchor 9.

[0022] For further optimization, a die-forged flower basket screw tightener 10 is arranged on the steel wire rope 4 between the second fixed pulley 8 and the ground anchor 9. The included angle between the steel wire rope 4 between the second fixed pulley 8 and the ground anchor 9 and the support beam 1 is not less than 45°. In this embodiment, this included angle can be taken as 50°. The first fixed pulley 3 is used to fix and fasten the running direction and tightness of the steel wire rope 4, and the second fixed pulley 8 and the rotating die-forged flower basket screw tightener 10 are used to adjust the tightness of the steel wire rope 4 to ensure the load-bearing strength of the steel wire rope 4. In reality, the distance between the two support beams 1 is at least about 17.5 meters, and there are relatively high requirements for the tightness and weighing strength of the steel wire rope 4.

[0023] For further optimization, a reinforcing beam rod is further arranged at the top end of the support beam. An inclined support is arranged between the horizontal beam and the support beam in the vertical plane, and a horizontal support is arranged between the horizontal beam and the reinforcing beam rod in the horizontal plane.

[0024] For further optimization, as Figure 3 shown, in order to improve the bending strength of the horizontal beam 2, a reinforcing beam rod 11 is further arranged at the top end of the support beam 1. The reinforcing beam rod 11 and the horizontal beam 2 are located in the same horizontal plane and are perpendicular to each other. An inclined support 12 is arranged between the horizontal beam 2 and the support beam to share the vertical tensile force transmitted by the steel wire rope 4 through the inclined support 12. A horizontal support 13 is arranged between the horizontal beam 2 and the reinforcing beam rod 11 in the horizontal plane to improve the bending strength of the horizontal beam 2 through the horizontal support 13. The mechanism here utilizes the stability of the triangle to improve the strength here.

[0025] This device can not only be applied to the tobacco industry for loading and unloading cartons, but also be used for cargo yard unloading in other industries.

[0026] Those skilled in the art will readily conceive of other embodiments of the present application after considering the specification and the practice disclosed herein. The present application is intended to cover any variations, uses, or adaptations of the present application, which follow the general principles of the present application and include the common general knowledge or conventional technical means in the technical field not disclosed in the present application.
