Technical Field
[0001] This utility model belongs to the technical field of mining trucks, specifically a protective device for explosion-proof glass on mining trucks. Background Technology
[0002] Mining trucks are heavy-duty dump trucks used in Lutian Mining for rock and soil stripping and ore transportation. Due to their special working environment, their windows are made of explosion-proof glass to prevent breakage or explosion when impacted by external objects, thus protecting the safety of the driver. However, while existing explosion-proof glass on mining trucks can effectively protect against impacts from small gravel, it can still be damaged when larger pieces of debris fall from the mine. Therefore, providing an explosion-proof glass protection device that improves protection performance and enables safe operation in harsh environments is an urgent problem to be solved. Utility Model Content
[0003] The technical problem to be solved by this utility model is to provide a protective device for explosion-proof glass of mining trucks to address the above-mentioned defects and solve the problems mentioned in the background art.
[0004] The technical solution adopted by this utility model to solve its technical problem is as follows: A mining truck explosion-proof glass protection device includes a truck windshield frame, a windshield mounting opening opened on the truck windshield frame, and an explosion-proof glass body disposed inside the windshield mounting opening. An engine hood is provided at the bottom of the front end face of the truck windshield frame. A protective mesh assembly covering the explosion-proof glass body is provided at the front end of the truck windshield frame. First connecting members are symmetrically arranged at the bottom of the protective mesh assembly. Fixing seats are symmetrically arranged at the top of the engine hood. The first connecting members and fixing seats... The protective mesh assembly is symmetrically provided with a second connector at its top. An installation strip is provided above the windshield mounting opening. An upper connecting block is symmetrically provided at the bottom end of the installation strip, which abuts against the rear end face of the second connector. The second connector and the upper connecting block are fixedly connected by fasteners. A lower connecting block is symmetrically provided on the upper surface of the hood, which is fixedly connected to the second connector by fasteners. The lower connecting block, the lower connecting block and the second connector are on the same central axis. Support members that support the protective mesh assembly are symmetrically provided on both sides of the windshield mounting opening.
[0005] Furthermore, the protective mesh panel assembly includes a rectangular outer frame and a reinforcing rod vertically arranged in the middle of the outer frame. The reinforcing rod divides the interior of the outer frame into two protective zones. The protective zones are equipped with mesh-like iron protective rods, and the two ends of the iron protective rods are respectively connected to the inner wall of the outer frame and the inner side wall of the reinforcing rod.
[0006] Furthermore, a gap is left between the rear end face of the protective mesh panel assembly and the front end face of the explosion-proof glass body.
[0007] Furthermore, the mounting base has an installation groove, and the bottom end of the first connector extends into the installation groove and is rotatably connected to the inner walls on both sides of the installation groove.
[0008] Furthermore, the second connector has a first connection hole, the upper connector has a second connection hole that communicates with the first connection hole, and the lower connector has a third connection hole.
[0009] Furthermore, the support member includes a vertical section that is vertically mounted on the truck windshield frame, and a limiting section is provided along the length of the front end face of the vertical section, the vertical section and the limiting section forming an L-shaped structure.
[0010] Furthermore, reinforcing components are provided at the connection points between the first connector, the second connector, and the protective mesh assembly.
[0011] Furthermore, the reinforcing component includes a first fixing member disposed on the horizontal section of the protective mesh assembly, a second fixing member disposed on the sidewalls of the first and second connectors, and a first inclined section disposed between the first and second fixing members. The first inclined section forms a triangular stable structure with the horizontal section of the protective mesh assembly, the first connector, and the second connector. A second inclined section is disposed at the middle of the inner wall of the first inclined section, extending towards the corner formed at the connection between the first connector, the second connector, and the protective mesh assembly. The second inclined section is perpendicular to the first inclined section.
[0012] The beneficial effects of this utility model are:
[0013] This utility model, through the coordinated arrangement of a protective mesh panel assembly, a first connector, a fixing base, a second connector, an mounting strip, fasteners, a lower connecting block, and an upper connecting block, allows the first connector to flip on the fixing base when the mining truck is operating in harsh and special environments. This causes the second connector to align with the upper connecting block, and the fasteners lock the second connector to the upper connecting block, thus covering the explosion-proof glass body with the protective mesh panel assembly. When large foreign objects fall and impact the explosion-proof glass body, they are intercepted and blocked by the protective mesh panel assembly, preventing them from hitting the explosion-proof glass body. When protection is not needed, the fasteners can be removed, the first connector can be flipped, the second connector can align with the lower connecting block, and the fasteners lock the second connector to the lower connecting block, fixing the protective mesh panel assembly to the top of the hood. This effectively improves the protective performance of the explosion-proof glass, making the mining truck safer to operate in harsh and special environments. Attached Figure Description

An engine hood 4 is provided at the bottom of the front end of the truck windshield frame 1. The truck windshield frame 1 is specifically an outer frame of the vehicle's cab. A protective mesh assembly 5 is provided at the front end of the truck windshield frame 1 to cover the explosion-proof glass body 3. When a large foreign object falls and impacts the explosion-proof glass body, it is intercepted and blocked by the protective mesh assembly, preventing it from hitting the explosion-proof glass body, effectively improving the protective performance of the explosion-proof glass and making the mining truck safer to operate in harsh and special environments. A first connecting member 6 is symmetrically provided at the bottom of the protective mesh assembly 5, and a fixing seat 7 is symmetrically provided at the top of the engine hood 4. The first connecting member 6 is rotatably connected to the fixing seat 7, and the first connecting member 6 flips on the fixing seat 7, causing the protective mesh assembly... 5. The protective mesh assembly 5 is flipped from the engine hood 4 to the front end of the explosion-proof glass body 3, forming a cover and protecting the explosion-proof glass body 3. The top of the protective mesh assembly 5 is symmetrically provided with a second connector 8. The windshield mounting opening 2 is provided with a mounting strip 9. The mounting strip 9 can be bolted or welded to the truck windshield frame 1. The bottom end of the mounting strip 9 is symmetrically provided with an upper connecting block 10 that abuts against the rear end face of the second connector 8. When the protective mesh assembly 5 is located at the front end of the explosion-proof glass body 3, the rear end face of the second connector 8 abuts against the front end face of the upper connecting block 10. The second connector 8 and the upper connecting block 10 are fixedly connected by a fastener 11. The fastener 11 consists of a screw and a screw block fixed to one end of the screw. The fastener passes through the second connector 8 and is fixedly connected to the upper connecting block 10, so that the protective mesh assembly 5 is fixed to the front end face of the explosion-proof glass body 3 and will not shift due to bumps and vibrations.
[0024] The upper surface of the engine hood 4 is symmetrically provided with lower connecting blocks 12 that are fixedly connected to the second connecting piece 8 by fasteners 11. When the mining truck does not need to use the protective mesh assembly 5, the protective mesh assembly 5 is placed on the engine hood 4 by flipping the first connecting piece 6. The second connecting piece 8 corresponds to the lower connecting block 12 and is threadedly connected to the lower connecting block 12 by fasteners 11 passing through the second connecting piece 8, thus fixing the protective mesh assembly 5 on the engine hood 4 to prevent it from jumping and impacting the engine hood 4 due to bumps and vibrations. The lower connecting block 12, the upper connecting block 10, and the second connecting piece 8 are on the same central axis. Supporting pieces 13 are symmetrically provided on both sides of the windshield mounting opening 2 to support the protective mesh assembly 5. The front end face of the supporting piece 13 abuts against the rear end face of the protective mesh assembly 5. When the protective mesh assembly 5 is impacted, the supporting piece 13 provides certain support, making the structure of the protective mesh assembly 5 more stable and less prone to rearward deformation.
[0025] Preferably, the protective mesh assembly 5 includes a rectangular outer frame 501 and a reinforcing rod 502 vertically arranged in the middle of the outer frame 501. The reinforcing rod 502 divides the interior of the outer frame 501 into two protective zones. A grid-like iron protective rod 503 is provided inside the protective zone. The two ends of the iron protective rod 503 are connected to the inner wall of the outer frame 501 and the inner side wall of the reinforcing rod 502, respectively. The outer frame 501, the reinforcing rod, and the iron protective rod 503 are made of the same material, and their grid-like structure facilitates the driver's observation of the exposed conditions while providing coverage and protection for the explosion-proof glass body 3.
[0026] Preferably, there is a gap between the rear end face of the protective mesh assembly 5 and the front end face of the explosion-proof glass body 3, the gap preventing the protective mesh assembly 5 from impacting the explosion-proof glass body 3 when it collapses.
[0027] Preferably, the mounting base 7 has an installation groove 701, the bottom end of the first connector 6 extends into the installation groove 701 and is rotatably connected to the inner walls on both sides of the installation groove 701. The two sides of the first connector 6 are rotatably connected to the inner side walls of the installation groove 701 of the mounting base 7 through a rotating shaft, so that the protective mesh panel assembly 5 can be flipped in the mounting base 7.
[0028] Preferably, the second connecting member 8 has a first connecting hole 801, the upper connecting block 10 has a second connecting hole 1001 communicating with the first connecting hole 801, and the lower connecting block 12 has a third connecting hole 1201. When the second connecting member 8 is connected to the upper connecting block 10 fixing plate, one end of the fastener 11 passes through the first connecting hole 801 and is threaded to the second connecting hole 1001. When the second connecting member 8 is fixedly connected to the lower connecting block 12, one end of the fastener 11 passes through the first connecting hole 801 and is threaded to the third connecting hole 1201.
[0029] Preferably, the support member 13 includes a vertical section 1301 vertically disposed on the truck windshield frame 1, and a limiting section 1302 disposed along the length of the front end face of the vertical section 1301. The vertical section 1301 and the limiting section 1302 form an L-shaped structure. The front end face of the vertical section 1301 abuts against the rear end face of the outer frame 501, and the inner side wall of the limiting section 1302 abuts against the outer side wall of the outer frame 501, thus providing support and limiting for the protective mesh assembly 5. When the protective mesh assembly is subjected to rearward impact or impacts from other directions, the vertical section 1301 provides support for the outer frame 501, and the limiting section 1302 limits it, making it more stable during protection and providing better protection.
[0030] Preferably, a reinforcing component 14 is provided at the connection between the first connector 6, the second connector 8 and the protective mesh assembly 5. The reinforcing component 14 improves the structural strength and stability between the first connector 6, the second connector 8 and the outer frame 501, and makes the connection less prone to deformation and damage when subjected to external forces.
[0031] Preferably, the reinforcing component 14 includes a first fixing member 1401 disposed on the horizontal section of the protective mesh assembly 5, a second fixing member 1402 disposed on the sidewalls of the first connecting member 6 and the second connecting member 8, and a first inclined section 1403 disposed between the first fixing member 1401 and the second fixing member 1402. The first inclined section 1403, together with the horizontal section of the protective mesh assembly 5, the first connecting member 6, and the second connecting member 8, forms a triangular stable structure. A groove is provided at the middle of the inner wall of the first inclined section 1403, extending towards the connection point between the first connecting member 6, the second connecting member 8, and the protective mesh assembly 5. The second inclined segment 1404 extends from the corner of the structure. The second inclined segment 1404 is perpendicular to the first inclined segment 1403. The first fixing member 1401, the second fixing member 1402, the first inclined segment 1403, the second inclined segment 1404 are welded to the outer frame 501, the first connecting member 6, and the second connecting member 8. The first inclined segment 1403 and the second inclined segment 1404 form an isosceles triangle structure at their connection, which makes the structure stronger and more stable. The connection is less prone to fracture deformation, thus improving its service life and stability during protection.
[0032] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications or equivalent changes made to the above embodiments based on the technical essence of the present utility model shall fall within the protection scope of the present utility model.
