[0028] like Figures 1 to 3As shown, a preferred embodiment of the present invention provides a deck guardrail for an engineering vehicle, comprising a main guardrail 1, a plurality of main connecting components 101 for being installed on the edge of a deck 2 of an engineering vehicle and connecting the main guardrail 1, and a positioning rod 1014 fixed on the deck 2 and resting against the inner side of the main guardrail 1; the projection of the central axis of the positioning rod 1014 on the deck 2 intersects with the longitudinal center line of one of the main connecting components 101. The multi-point connection of the main connection component 101 and the support and positioning of the positioning rod 1014 work together to disperse external forces, prevent the main guardrail 1 from deformation and displacement, and accurately position it, thereby ensuring the accuracy and stability of the installation of the entire guardrail system; the coordinated action of multiple main connection components 101 and the positioning rod 1014 effectively prevents the guardrail from loosening or shifting, avoiding danger to surrounding personnel and equipment due to guardrail problems during the operation of engineering vehicles; in terms of installation and maintenance, this structure provides installers with a clear installation reference point, and the layout of multiple main connection components 101 and the relationship between the positioning rod 1014 and the main connection component 101 simplifies the installation process, helps to improve the assembly efficiency of engineering vehicles, and reduces installation time and labor costs.

[0029] Specifically, multiple main connecting assemblies 101 are secured to the deck 2 via bolts. The lengths of some of the connecting assemblies or their bolts are perpendicular to the lengths of other connecting assemblies or their bolts. The connecting assemblies or bolts in different orientations effectively disperse and resist external forces from various directions, such as vertical bolts resisting vertical forces and horizontal bolts resisting horizontal forces. They also enhance the overall structural strength, supporting each other like a frame structure. This prevents the guardrail from tilting or collapsing due to uneven force distribution, ensuring the guardrail's stability and continued protective function.

[0030] In this embodiment, the main connecting component 101 includes a first connecting component 1011, a second connecting component 1012 and a third connecting component, wherein the center line of the second connecting component 1012 and the positioning rod 1014 are on the same straight line, and the length direction of the third connecting component or its bolt is perpendicular to the length direction of the first connecting component 1011 or its bolt.

[0031] Specifically, in this embodiment, the main guardrail 1 includes a main guardrail riser 110 disposed within the main connection assembly 101 and a main guardrail cross tube 109 perpendicularly connected to the main guardrail riser 110. The main guardrail riser 110, disposed within the main connection assembly 101, serves as the vertical support structure for the main guardrail 1. Connected to the deck 2 via the main connection assembly 101, it vertically supports the main guardrail 1. The main guardrail cross tube 109, perpendicularly connected to the main guardrail riser 110, serves as a horizontal structural component that expands the protection range horizontally and provides lateral connection and support for the main guardrail riser 110. The two are vertically connected to form a frame structure that effectively transmits force in both vertical and horizontal directions.

[0032] In this embodiment, the engineering vehicle deck guardrail also includes a secondary guardrail 3 for installation on the edge of the deck 2 in an area above the engineering vehicle radiator. The secondary guardrail 3 includes a limiting plate 303 fixed on the radiator deck 4 and a secondary guardrail riser 301 passing through the limiting plate 303.

[0033] Specifically, there are multiple limiting plates 303 , and the length direction of a portion of the limiting plates 303 is arranged to be perpendicular to the length direction of another portion of the limiting plates 303 .

[0034] Specifically, the secondary guardrail further includes a secondary guardrail transverse tube 302 vertically connected to the secondary guardrail vertical tube 301. The secondary guardrail transverse tube and the secondary guardrail vertical tube 301 are vertically connected to form a frame structure, so that force can be effectively transmitted in the vertical and horizontal directions.

[0035] Specifically, the construction vehicle deck guardrail includes a secondary guardrail 3, which is mounted on the radiator deck 4 at the edge of the area above the construction vehicle's radiator. The secondary guardrail comprises a stop plate 303 and a secondary guardrail riser 301. The stop plate 303 is fixed to the radiator deck 4, and the secondary guardrail riser 301 is inserted through the stop plate 303. Multiple stop plates 303 are provided, with some portions of these stop plates 303 arranged perpendicular to one another along their lengths. This arrangement of multiple stop plates 303, with portions of their lengths perpendicular to one another, effectively supports the secondary guardrail in various directions. When the construction vehicle is subjected to external forces from various directions, such as swaying or collisions during driving, this arrangement provides multiple resistance from various angles, reducing the risk of deformation or damage to the secondary guardrail. The relatively regular structural layout facilitates accurate installation by installers, improving installation efficiency. Furthermore, during subsequent maintenance, the clear structure allows for quick location and repair of components such as the stop plates 303 or the secondary guardrail riser 301 should any problems arise.

[0036] Specifically, the engineering vehicle deck guardrail also includes a connecting component 5 for connecting the main guardrail 1 and the secondary guardrail 3. The connecting component 5 includes connecting clips 501 symmetrically arranged on the main guardrail 1 and the secondary guardrail 3, and a connecting plate 502 connected between the connecting clips 501.

[0037] This connecting assembly 5 establishes a stable connection between the main guardrail 1 and the secondary guardrail assembly. The connecting buckles 501 are symmetrically arranged on the two, ensuring the accuracy and stability of the connection, so that the main and secondary guardrail assemblies can work together. The connecting plate 502 further strengthens this connection, making the entire guardrail system more integrated. During the operation of the engineering vehicle, whether it is subjected to vibration, shaking or external impact, this connection method can effectively prevent the main and secondary guardrail assemblies from being disconnected or relatively displaced, thereby ensuring that the overall protective function of the guardrail can be continuously exerted. In addition, this structure is more convenient during installation and maintenance. The structure of the connecting buckle 501 and the connecting plate 502 is relatively simple, easy for installers to operate, and can also be quickly located and processed when repairs or replacement of parts are required.

[0038] In this embodiment, the deck 2 and the main guardrail 1, the radiator deck 4 and the secondary guardrail 3 are fixed with bolts in multiple directions. The different arrangement directions of the main connection assembly 101 and the limit plate 303 effectively eliminate the safety hazard of cracking of welds and structures in harsh mining environments due to excessive cantilever structures of the guardrails and too single connection direction, without other support directions and support positioning points.

[0039] In this embodiment, the engineering vehicle deck guardrail further includes a field of view adjustment assembly, comprising a convex mirror bracket 102 rotatably mounted on the main guardrail 1 and a convex mirror secured to the convex mirror bracket 102. The convex mirror bracket 102 is rotatably mounted on the main guardrail 1, and the convex mirror is secured to the bracket. This arrangement expands the field of view, improves operational safety, adapts to various operating conditions, and demonstrates structural flexibility and integration.

[0040] Specifically, the convex mirror includes a mounting block 103 fixed on a convex mirror bracket 102, a mounting support 104 installed on the side of the convex mirror and fixedly connected to the mounting block 103, and a lens 105 movably mounted on the mounting support 104. The mounting support 104 is provided with a through hole for adjusting the upper and lower positions of the lens 105.

[0041] Specifically, the mounting block 103 includes a first fixed block 106 installed between the mounting support 104 and the convex mirror bracket 102, a second fixed block 107 installed on the other side of the convex mirror bracket 102, and a threaded plate 108 for fixing the second fixed block 107. Threaded holes are provided on the first fixed block 106 and the threaded plate 108, and a through hole is provided on the second fixed block 107 for the threaded plate 108 to pass through.

[0042] Specifically, the field of view adjustment assembly further includes a fixing bolt that passes through the threaded hole and fixes the mounting block 103 to the convex mirror bracket 102.

[0043] This convex mirror structure has many advantages. The movable lens 105 can be adjusted up and down through the through-holes on the mounting bracket 104, which allows the operator to flexibly adjust the position of the lens 105 according to his or her own viewing angle and actual observation needs, thereby obtaining the best field of view. For example, when operators of different heights use an engineering vehicle, they can adjust to a suitable height for clear observation. The fixing bolts fix the mounting block 103 to the convex mirror bracket 102, ensuring the stability of the overall structure of the convex mirror. During the driving or operation of the engineering vehicle, even if it is affected by external forces such as vibration, the convex mirror can remain stable, ensuring that the field of view adjustment function is not interfered with, and continuously providing the operator with accurate surrounding environment information, thereby improving the safety and efficiency of engineering vehicle operation.

[0044] The present application provides a deck guardrail for engineering vehicles, which has many beneficial effects: in terms of structural stability, the multi-point connection of the main connection assembly 101 can disperse the external force borne by the main guardrail 1, making the main guardrail 1 more firmly fixed on the deck 2. The positioning rod 1014 can not only prevent the main guardrail 1 from deforming or displacing inward, but also accurately determine the installation position of the main guardrail 1 through a specific intersection relationship with the main connection assembly 101, thereby ensuring the accuracy and stability of the installation of the entire guardrail system. In terms of safety, the synergistic effect of multiple main connection assemblies 101 and the positioning rod 1014 effectively prevents the guardrail from loosening or shifting, avoiding danger to surrounding personnel and equipment due to guardrail problems during the operation of engineering vehicles. At the same time, precise installation ensures that the protection range of the main guardrail 1 meets the design requirements, can effectively prevent goods, personnel, etc. from accidentally slipping or approaching dangerous areas, and improve the safety of engineering vehicle operations. This structure provides installers with clear reference points for installation and maintenance. The layout of the multiple main connection assemblies 101 and the relationship between the positioning rods 1014 and the main connection assemblies 101 simplify the installation process, helping to improve the assembly efficiency of engineering vehicles and reduce installation time and labor costs. Furthermore, during maintenance, the clear connection structure and positioning relationships allow maintenance personnel to quickly locate and address problematic components, eliminating the need for complex disassembly and reassembly, reducing maintenance difficulty and costs.

Any modifications or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention.
