Description

Technical Field

[0001] The utility model relates to the technical field of ports and docks, in particular to a guardrail. Background Art

[0002] Port terminals are facilities for ships to dock, load and unload goods, and get people on and off. They are usually located in waters such as seaports or estuaries. They are important interfaces between land and sea, and are also key links in international trade and shipping. When operating at port terminals, in order to protect the safety of staff and loading and unloading goods, corresponding guardrails are usually set up at the port terminals. Guardrails refer to fences set up to protect people's safety. They are usually used to enclose dangerous areas to prevent people from entering or leaving the area. They have protective, warning and guiding functions. The setting of guardrails can prevent people from accidentally falling into the water, can prevent goods from falling from the dock, and can ensure the safety and efficiency of dock operations, while also improving the safety and operating efficiency of port terminals.

[0003] At present, in order to dismantle the guardrail when not in use to avoid affecting the appearance, most people choose to install detachable guardrails around docks and ports. When installing the detachable guardrail, it is necessary to rotate the turntables at both ends of the crossbar one by one to make both ends of the upper and lower crossbars contact the wall. In addition, in order to make the contact force between the two ends of the crossbar and the wall the same and ensure the stability of the crossbar fixation, it is necessary to repeatedly adjust the turntable. The operation is cumbersome and takes a lot of time. For example, in the patent document with announcement number CN220353586U, a port and dock guardrail is disclosed. A fixed steel frame is provided, plug blocks are provided at both ends of the billboard, a mounting seat is provided on the side of the billboard, a pad is provided on the inner side of the mounting seat, fixed frames are provided at both ends of the mounting seat, a sliding block is provided on the fixed front, the side of the sliding block is provided on the L-shaped plate, and a discharge chute is provided on the side of the fixed frame, which can prevent pedestrians from climbing the baffle and the fixed steel frame, thereby realizing interception protection for the periphery of the port terminal, and cooperating with the fixed cone to drive the fixed column to be fixed underneath, thereby improving the stability of the fixed column, avoiding the fixed column driving the baffle to tilt or dump due to impact, and improving the service life of the device.

[0004] The plug blocks at both ends of the baffle are respectively embedded in the slots at the side ends of the fixed columns and fit tightly together, and the positioning seat and the top surface of the baffle are fixedly connected to the fixed steel frame and the conical steel column. Although it can prevent pedestrians from climbing the baffle and the fixed steel frame, thereby realizing interception protection for the periphery of the port terminal, but in the prior art, when the guardrail is set at the port terminal, the height generally set is fixed. When loading and unloading goods at the port terminal, the goods are often stacked and palletized. The height of the guardrail with a fixed height cannot be adjusted well according to the height of the stacked goods. When the goods are stacked higher, the guardrail cannot well prevent the goods from falling from the dock or crossing the boundary. The flexibility of the use of the guardrail needs to be improved. Therefore, in order to solve the above problems, a guardrail is proposed. Utility Model Content

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-4 , an embodiment provided by the utility model:

[0024] A guardrail comprises a column, wherein the column comprises a column 1, and a first cross bar 11 is fixedly connected to the surface of the column 1. The columns 1 can be connected by the first cross bar 11, so that the columns 1 and the first cross bar 11 can block people and goods, thereby effectively preventing people or goods from falling.

[0025] An adjustment mechanism is provided on the inner side of the column 1, and the adjustment mechanism includes a rotating rod 2, which is movably connected to the inner side of the column 1, and a first conical tooth 21 is fixedly connected to the surface of the rotating rod 2, and a screw rod 22 is movably connected to the inner side of the column 1, and a second conical tooth 23 is fixedly connected to the surface of the screw rod 22, and an extension rod 24 is threadedly connected to the surface of the screw rod 22, and a second cross bar 25 is fixedly connected to the surface of the extension rod 24. Through the setting of the extension rod 24, when the screw rod 22 rotates, the extension rod 24 can move on the inner side of the column 1, thereby extending the overall height of the guardrail, so that the guardrail can better prevent goods from falling or crossing the boundary.

[0026] Furthermore, the adjustment mechanism also includes a limit block 26, which is fixedly connected to the surface of the extension rod 24. A limit groove 27 is provided on the inner wall of the column 1. Through the cooperation of the limit block 26 and the limit groove 27, the extension rod 24 can be limited, so that the extension rod 24 can be prevented from deflecting under the action of the screw rod 22, so that the extension rod 24 can stably drive the second cross bar 25 to rise and fall.

[0027] Furthermore, the rotating rods 2 are connected to the columns 1 in two groups, the screw rods 22 are connected to the columns 1 in two groups, and the extension rods 24 are movably connected to the columns 1. By rotating the screw rods 22, the extension rods 24 can be raised and lowered on the inner side of the columns 1, so that when stacking and loading and unloading goods, the height of the columns 1 and the first cross bar 11 can be flexibly adjusted according to the stacking height of the goods.

[0028] Furthermore, the limit blocks 26 are in two groups fixedly connected to the surface of the extension rod 24, and the limit grooves 27 are in two groups opened on the inner wall of the column 1. The end of the limit block 26 away from the extension rod 24 is movably connected to the limit groove 27. Through the opening of the limit groove 27, it is convenient for the extension rod 24 to slide on the surface of the limit groove 27 through the limit block 26, thereby facilitating the extension rod 24 to be stably raised and lowered on the inner side of the column 1.

[0029] Furthermore, a protective mechanism is provided on the surface of the first cross bar 11, and the protective mechanism includes a fixed rod 3, which is fixedly connected to the surface of the first cross bar 11, a sleeve rod 31 is movably connected to the surface of the fixed rod 3, a protective plate 32 is fixedly connected to the surface of the sleeve rod 31, a first spring 33 is fixedly connected to the surface of the first cross bar 11, and a second spring 34 is fixedly connected to the surface of the column 1. Through the provision of the protective plate 32, when a collision occurs, the impact force caused by the collision will not directly act on the column 1 and the first cross bar 11, thereby being able to protect the column 1 and the first cross bar 11, which is beneficial to extending the service life of the guardrail.

[0030] Furthermore, the fixing rods 3 are evenly distributed on the surface of the first cross bar 11 in eight groups, one end of the first spring 33 is fixedly connected to the first cross bar 11, and the other end of the first spring 33 is fixedly connected to the sleeve rod 31. The first cross bar 11 and the protective plate 32 are connected by the first spring 33, so that when a collision occurs, the first spring 33 can alleviate the impact to a certain extent, thereby being able to play a certain protective role on the first cross bar 11 and reducing the deformation or breakage of the first cross bar 11.

[0031] Furthermore, one end of the second spring 34 is fixedly connected to the column 1, and the other end of the second spring 34 is fixedly connected to the protective plate 32. Through the arrangement of the second spring 34, when an external force collides with the protective plate 32, the elastic property of the second spring 34 can reduce the damage to the column 1 caused by the impact, thereby reducing the impact on the column 1.

[0032] Working principle: When in use, by rotating the rotating rod 2, the first conical teeth 21 will rotate under the action of the rotating rod 2, and then the second conical teeth 23 will rotate under the action of the first conical teeth 21 and drive the screw 22 to rotate. The extension rod 24 is limited by the limit block 26 and the limit groove 27, and will move on the inner side of the column 1 under the action of the screw 22, so that the extension rod 24 can drive the second cross bar 25 to rise and fall, so that the height of the column 1 and the first cross bar 11 can be extended;

[0033] When the external force impacts the guardrail, it will first act on the guard plate 32. The setting of the guard plate 32 can prevent the external force from directly colliding with the column 1 and the first cross bar 11. The impact on the guard plate 32 will cause the sleeve rod 31 to move on the surface of the fixed rod 3, and then the first spring 33 and the second spring 34 will be deformed. The elastic properties of the first spring 33 and the second spring 34 can alleviate the impact caused by the collision to a certain extent, thereby reducing the conduction to the column 1 and the first cross bar 11, thereby achieving protection of the guardrail.

[0034] The above are only preferred embodiments of the present invention and are not intended to limit the present invention in any form. Any ordinary technician in the industry can smoothly implement the present invention as shown in the drawings and above. However, any equivalent changes, modifications and evolutions made by technicians familiar with the profession without departing from the scope of the technical solution of the present invention using the technical content disclosed above are all equivalent embodiments of the present invention. At the same time, any equivalent changes, modifications and evolutions made to the above embodiments based on the essential technology of the present invention are still within the protection scope of the technical solution of the present invention.
