Technical Field

[0001] The utility model belongs to the technical field of cargo loading and unloading protective guardrails, and in particular relates to a protective structure for cargo loading and unloading. Background Art

[0002] Cargo loading and unloading is the process of loading and unloading cargo before and after transportation. During cargo loading and unloading, the sides of the loading and unloading area need to be protected. Usually, guardrails are used to protect the loading and unloading area. Existing guardrails are devices used for protecting both sides of the loading and unloading area during cargo loading and unloading. The guardrails are easy to adjust in length during use and are suitable for protection at different cargo loading and unloading areas, thereby improving the convenience of remote protection adjustment of the guardrails at the loading and unloading area.

[0003] When the existing guardrails are used for cargo loading and unloading protection, the guardrails are directly fixed on both sides of the cargo loading and unloading position for protection, and it is not convenient to adjust the length of the guardrails after they are fixed and installed. When loading and unloading cargo over long distances, it is necessary to temporarily use external guardrails for protection again, and the temporarily used guardrails cannot be quickly found and installed, which makes the protection operation inconvenient and cumbersome, affecting the convenience of adjusting the length of the guardrails during long-distance loading and unloading operations of cargo. For this reason, the utility model proposes a protective structure for cargo loading and unloading. Utility Model Content

[0030] Example 2

[0031] See also Figure 1 、 Figure 2 、 Figure 5 and Figure 6 The utility model provides a technical solution: a protective structure for cargo loading and unloading, including a guardrail 100, the guardrail 100 includes a fixed main column 102, and main guardrail panels 101 are welded and fixed on both sides of the fixed main column 102, and the two main guardrail panels 101 are symmetrically arranged through the fixed main column 102, and a fixed base 103 is welded and fixed at one end of the bottom of the main guardrail panel 101, which is fixedly installed at the middle position on both sides of the loading and unloading cargo through the fixed main column 102. After the fixed main column 102 is fixed, the guardrail panel 100 is fixedly installed on both sides of the loading and unloading cargo, and after the fixed installation, the bottom end of the fixed base 103 contacts the ground and is reinforced and installed again, so that the guardrail panel 100 is fixedly installed on both sides of the loading and unloading cargo position for isolation and safety protection. The guardrail panel 100 is also provided with:

[0032] A buffer protection mechanism includes a protection component arranged inside the extended protection component, and an elastic buffer component is provided at the end of the protection component. The guardrail 100 can be fixedly installed to open the protection for the auxiliary guardrail 1011. The buffer protection mechanism provides surface buffering protection for the main guardrail 101 and the auxiliary guardrail 1011, thereby extending the service life and improving the buffering protection effect of the guardrail 100 when protecting the loading and unloading of goods.

[0033] In order to facilitate the surface buffering protection of the auxiliary guardrail plate 1011 through the protection component and prevent it from being deformed and damaged easily when impacted, in this embodiment, preferably, the protection component includes three buffer grooves 104 opened inside the auxiliary guardrail plate 1011, and a buffer protection plate 1041 is provided inside the buffer groove 104. The two side surfaces of the main guardrail plate 101 are fixed with rubber buffer pads 1046 by screws. When the guardrail plate 100 is in use, the rubber buffer pads 1046 can be deformed to provide buffering protection for the surface of the main guardrail plate 101. At the same time, the buffer protection plate 1041 can provide buffering protection for the surface of the main guardrail plate 101, so that the guardrail plate 100 can be installed and used for buffering protection.

[0034] In order to facilitate the buffer protection of the buffer protection plate 1041 when it is hit by the elastic buffer component and not easily cause deformation and damage due to impact, in this embodiment, preferably, the elastic buffer component includes two connecting grooves 1042 opened at both ends of the buffer groove 104, and a sliding rod 1044 is provided inside the connecting groove 1042. A slider 1043 is slid at the middle position of the sliding rod 1044. The bottom end of the slider 1043 is fixed to the end of the buffer protection plate 1041 by welding, and buffer springs 1045 are installed on both sides of the slider 1043 on the outer surface of the sliding rod 1044. After the guardrail 100 is installed, when the auxiliary guardrail plate 1011 is opened for protection, the buffer spring 1045 is deformed to drive the slider 1043 to slide on the outer surface of the sliding rod 1044, thereby driving the buffer protection plate 1041 to buffer and protect inside the buffer groove 104, which is convenient for buffer protection.

[0035] The working principle and use process of the utility model are as follows: when using this cargo loading and unloading protective structure, the main columns 102 are fixedly installed at the middle position on both sides of the loading and unloading cargo, and after the main columns 102 are fixed, the guardrail panels 100 are fixedly installed on both sides of the loading and unloading cargo, and after the fixed installation, the bottom end of the fixed base 103 contacts the ground and is reinforced again, so that the guardrail panels 100 are fixedly installed on both sides of the loading and unloading position for isolation and safety protection;

[0036] Then, when the guardrail panel 100 is loaded and unloaded over a long distance after installation, the hand wheel 1014 can be held to drive the two-way screw rod 1015 to rotate, and the two-way screw rod 1015 rotates to move the two movable seats 1016 toward each other. When the two movable seats 1016 move toward each other, they drive the two support rods 1019 to support and open. When the support is opened, the support rod 1019 drives the support slider 1017 to slide inside the support slide groove 1018 and push the auxiliary guardrail panel 1011. When the auxiliary guardrail panel 1011 is pushed open inside the main guardrail panel 101, it drives the control slider 1010 The auxiliary guardrail plate 1011 is stably supported and opened by stably controlling the sliding inside the control slide. After opening, the locking bolt 1013 is rotated to fix the auxiliary guardrail plate 1011 and the main guardrail plate 101. After the auxiliary guardrail plate 1011 is opened and fixed, it is stably supported by the auxiliary column 1012, so that the guardrail plate 100 is easy to adjust for long-distance safety protection during protection. The length adjustment protection operation is simple and convenient, and the length adjustment protection is convenient for different distances, thereby improving the convenience of the long-distance protection adjustment operation of the guardrail plate 100 at the loading and unloading of goods.

[0037] Finally, when the guardrail 100 is opened for long-distance protection, when the outer surfaces of the main guardrail 101 and the auxiliary guardrail 1011 are hit during loading and unloading of goods, the external objects generated by loading and unloading of goods are directly hit on the surface of the buffer protection plate 1041 and the rubber buffer pad 1046, so that the rubber buffer pad 1046 is deformed under the force to buffer and protect the impacted objects. At the same time, the buffer protection plate 1041 is deformed by the force on the buffer spring 1045. The deformation of the buffer spring 1045 drives the slider 1043 to elastically buffer the outer surface of the slide rod 1044. The elastic buffering of the slider 1043 drives the buffer protection plate 1041 to elastically buffer the inside of the buffer groove 104, so that when the surface of the buffer protection plate 1041 is hit, it is convenient for buffering protection, which is convenient for buffering protection when the guardrail 100 is installed for protection, extending the service life, and improving the buffering protection effect of the guardrail 100 during loading and unloading of goods.
