Description

Technical Field

[0001] This invention relates to the field of coal transport equipment technology, and in particular to an underground coal transport vehicle. Background Technology

[0002] As a common transportation tool in mines, underground coal transport vehicles have high standards in terms of frame quality, power, and safety. The purpose is to ensure the safety of drivers when operating the vehicles for coal transportation in mines. At present, the cabs of coal transport vehicles are reinforced by adding reinforcing ribs to the frame or by setting up multiple escape windows and suspended driving seats to ensure the driver's chances of survival in the event of a mine collapse.

[0003] Existing safety measures for drivers in coal transport vehicles still have certain shortcomings. While reinforced structures are installed to ensure the impact resistance of the cab roof, the impact of debris on the cab can cause significant resonance, leading to temporary loss of consciousness in the driver and missing the best escape judgment. When the cab is severely deformed by an impact, the driver cannot quickly unfasten the seat belt to avoid injury, resulting in head trauma. Furthermore, when vehicles are deformed and buried in mine collapses, drivers cannot obtain escape supplies. Summary of the Invention

[0004] The purpose of this invention is to solve the problems in the prior art where, when a collapsed object impacts the cab, causing resonance and deformation inside the cab, the driver's head is injured, affecting the driver's judgment and survival ability, and the driver is unable to obtain escape supplies when the vehicle is buried. Therefore, an underground coal transport vehicle is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An underground coal transport vehicle includes a frame body and a front suspension plate. A guardrail assembly is provided on the outer top of the front suspension plate, and a driver's cab side protection assembly is provided on the top of the front suspension plate. Inside the driver's cab side protection assembly, the top of the front suspension plate contains a storage assembly, a shock-absorbing support assembly, and a delivery hole. A seat support platform is inserted into the inner wall of the delivery hole. A limiting ring is fixed to the periphery of the bottom of the seat support platform. A limiting tongue is inserted into the inner wall of the limiting ring. A slope is provided on the top of the limiting tongue. A support spring is fixed to one end of the limiting tongue, and a limiting top plate is fixed to one end of the support spring. A buffer assembly is provided on the lower surface of the seat support platform. A platform enclosure is fixed to the bottom of the delivery hole. An escape guard plate is hinged to the opening end of the platform enclosure. An anti-tilt assembly is provided on the inner wall of the platform side plate. The storage assembly includes a material storage cabinet fixed to the inner wall of the front suspension plate, and the bottom side of the material storage cabinet is provided with a cabinet enclosure plate. The anti-vibration support assembly includes a positioning trapezoidal hole on the upper surface of the front suspension plate. A trigger trapezoidal post is inserted into the inner wall of the positioning trapezoidal hole, and an anti-vibration buffer spring is fixed between the bottom of the trigger trapezoidal post and the inner bottom wall of the positioning trapezoidal hole.

[0007] Preferably, the front suspension plate is fixed to the top of the front driver support frame of the vehicle frame body, and the inner front side of the front suspension plate is fixed to the front of the vehicle frame body through a crash beam.

[0008] Preferably, the storage assembly further includes a corner support platform fixed to the inner wall of the material storage cabinet, the top of the corner support platform being tightly fitted with a partition plate, and the top of the material storage cabinet being hinged with a cabinet cover plate.

[0009] Preferably, the seismic support assembly further includes a suspension rod fixed to the top of the trigger trapezoidal column, the top of the suspension rod being fixed to the cockpit roof plate, and the bottom of the cockpit roof plate being fixed to a reinforcing bracket.

[0010] Preferably, the bottom of the platform enclosure is fixed with an escape protection base plate, which can be combined with the vehicle front suspension plate, the platform enclosure, the escape protection plate and the material storage cabinet to form an escape sealed cabin.

[0011] Preferably, the guardrail assembly includes a guardrail bar fixed to the surface of the front suspension plate.

[0012] Preferably, the cockpit side protection assembly includes a side protection barrier sleeved on the outside of the reinforcing bracket, the bottom of the side protection barrier being fixed to the surface of the front suspension plate, and the cockpit door being hinged to the open end of the side protection barrier.

[0013] Preferably, the buffer assembly includes a mounting sleeve fixed to the seat support platform, and a shock-absorbing spring is fixed to the inner wall of the mounting sleeve.

[0014] Preferably, the anti-tilt assembly includes an anti-tilt suspension plate fixed to the inner wall of the platform enclosure, and the inner sidewall of the anti-tilt suspension plate is located on the same plane as the outer side of the seat support platform.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. This invention, through the coordinated design of a trapezoidal column and a limiting latch, allows for shock absorption and vibration reduction when the cab roof is impacted by collapsing debris. This prevents severe deformation of the cab roof and reduces resonance caused by the impact, thus avoiding impact on the driver's consciousness and improving vehicle safety. When the collapse causes deformation of the cab roof, the trapezoidal column can be triggered to press down the limiting latch, allowing the seat support platform to be deployed into the escape compartment formed by the platform enclosure. This provides the driver with an escape opportunity to avoid major collapses. The driver can access the escape supplies in the storage cabinet by opening the cabinet's closing panel and escape promptly by opening the escape guard plate after the collapse has stabilized.

[0016] 2. The present invention utilizes the combined setup of a platform enclosure and a front suspension plate. The front suspension plate provides a platform to resist the collapse of debris, while the platform enclosure forms a safe haven under the front suspension plate to avoid the collapse, thereby increasing the driver's chances of survival and improving rescue opportunities.

[0017] 3. By strengthening the combination of the support frame and the side guardrail, when the collapsed material causes severe deformation of the cockpit roof, the suspension rod can descend through the positioning ladder hole to cause the cockpit roof to sink and buffer the impact of the collapsed material, preventing further deformation of the cockpit roof. The strengthening support frame descends with the cockpit roof and can serve as a strengthening frame for the side guardrail, preventing the collapsed material from squeezing and deforming the side guardrail. At the same time, the suspension rod can also serve as a support frame to prevent further deformation of the cockpit roof. Attached Figure Description

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0021] In the description of this invention, it should be noted that the terms "upper," "lower," "inner," "outer," "top / bottom," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0022] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "sleeved / connected," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0023] Example, refer to Figures 1 to 8 An underground coal transport vehicle includes a frame body 1 and a front suspension plate 2. The front suspension plate 2 is fixed to the top of the front driver support frame of the frame body 1, and the inner side of the front of the front suspension plate 2 is fixed to the front of the frame body 1 through a crash beam.

[0024] A guardrail assembly is provided on the outer top of the front suspension plate 2. Further, the guardrail assembly includes a railing bar fixed to the surface of the front suspension plate 2.

[0025] The further advantage of adopting the above is that the fence can block large pieces of collapsed material on the side, thereby reducing the squeezing force of large pieces of collapsed material on the side guard 23, preventing the side guard 23 from being severely deformed under pressure and exerting horizontal pressure on the reinforcing bracket 21, which would reduce the side support force of the protective cabin composed of the cockpit roof 20, reinforcing bracket 21 and side guard 23 and cause it to collapse.

[0026] The top of the front suspension plate 2 is provided with a driver's cabin side protection assembly. Further, the driver's cabin side protection assembly includes a side protection barrier 23 sleeved on the outside of the reinforcing bracket 21. The bottom of the side protection barrier 23 is fixed to the surface of the front suspension plate 2, and the opening end of the side protection barrier 23 is hinged to a driver's cabin door 24.

[0027] The further advantage of adopting the above is that after the reinforcing bracket 21 is inserted into the side guardrail 23, it can serve as the skeleton of the side guardrail, improve the pressure resistance of the side and top of the side guardrail 23, and improve the stability of the device.

[0028] The top of the front suspension plate 2 is located inside the driver's cabin side protection assembly and has a storage component, a shock-absorbing support component, and a release hole 3. A seat support platform 4 is inserted into the inner wall of the release hole 3. A limiting collar 5 is fixed to the periphery of the bottom of the seat support platform 4. A limiting tongue 6 is inserted into the inner wall of the limiting collar 5. A slope is opened on the top of the limiting tongue 6. A support spring 7 is fixed to one end of the limiting tongue 6. A limiting top plate 8 is fixed to one end of the support spring 7. A buffer component is provided on the lower surface of the seat support platform 4. Further, the buffer component includes a mounting sleeve fixed to the seat support platform 4. A shock-absorbing spring 25 is fixed to the inner wall of the mounting sleeve.

[0029] The further advantage of the above is that when the cockpit roof 20 is hit by collapsing objects, the suspension rod 19 can compress the shock-absorbing spring 15, causing the trigger trapezoidal column 14 to compress the limiting latch 6. The compression and contraction of the limiting latch 6 allows the seat carrying platform 4 to fall along the anti-tilt suspension plate 26 into the escape cabin formed by the platform enclosure 9 and the material storage cabinet 11, providing the driver with a refuge space. At the same time, when the trigger trapezoidal column 14 hits the limiting latch 6, the support spring 7 at one end of the limiting latch 6 can play a buffering and vibration reduction role, preventing excessive resonance in the cabin from causing damage to the driver's brain. The shock-absorbing spring 25 at the bottom of the seat carrying platform 4 can reduce the reaction force on the driver after the seat carrying platform 4 falls onto the escape protection base plate 22, reducing secondary injuries to the driver.

[0030] The bottom of the delivery hole 3 is fixed with a platform enclosure 9, the open end of the platform enclosure 9 is hinged with an escape guard plate 10, and the bottom of the platform enclosure 9 is fixed with an escape protection base plate 22. The escape protection base plate 22 can be combined with the front suspension plate 2, the platform enclosure 9, the escape guard plate 10 and the material storage cabinet 11 to form an escape sealed cabin.

[0031] The inner wall of the platform side panel 9 is provided with an anti-tilt component. Further, the anti-tilt component includes an anti-tilt suspension plate 26 fixed to the inner wall of the platform enclosure 9, and the inner side wall of the anti-tilt suspension plate 26 and the outer side of the seat carrying platform 4 are located on the same plane.

[0032] A further advantage of the above is that the anti-tilt suspension 26 can prevent the seat carrying platform 4 from tilting during the process of falling into the platform enclosure 9, which could cause injury to the driver's limbs.

[0033] The storage assembly includes a material storage cabinet 11 fixed to the inner wall of the front suspension plate 2. The bottom side of the material storage cabinet 11 is provided with a cabinet enclosure plate 12. Furthermore, the storage assembly also includes a corner support platform 16 fixed to the inner side wall of the material storage cabinet 11. The top of the corner support platform 16 is tightly fitted with a partition plate 17. The top of the material storage cabinet 11 is hinged with a cabinet top cover plate 18.

[0034] The further advantage of the above is that the partition 17 can divide the material storage cabinet 11 into two parts through the corner support 16. The top is for storing daily tools and the bottom is for storing escape supplies, which prevents the tools at the top from falling and hitting the driver when the driver opens the cabinet closing plate 12 to take away escape supplies.

[0035] The anti-vibration support assembly includes a positioning trapezoidal hole 13 on the upper surface of the front suspension plate 2. A trigger trapezoidal column 14 is inserted into the inner wall of the positioning trapezoidal hole 13. An anti-vibration buffer spring 15 is fixed between the bottom of the trigger trapezoidal column 14 and the inner bottom wall of the positioning trapezoidal hole 13. Furthermore, the anti-vibration support assembly also includes a suspension rod 19 fixed to the top of the trigger trapezoidal column 14. A driver's cab roof plate 20 is fixed to the top of the suspension rod 19, and a reinforcing bracket 21 is fixed to the bottom of the driver's cab roof plate 20.

[0036] The further advantages of the above are: the positioning trapezoidal hole 13 can provide a downward movement distance for the trigger trapezoidal column 14, and can provide a buffer space for the cockpit roof 20 after the collapse of the object, so as to reduce the resonance and deformation of the cockpit roof 20. At the same time, the downward movement of the trigger trapezoidal column 14 can cause the reinforcing bracket 21 to enter the side guardrail 23 as a reinforcing frame. When the trigger trapezoidal column 14 moves down to the lowest position, it can cause the suspension rod 19 to support the cockpit roof 20, preventing the cockpit roof 20 from being deformed and collapsed under pressure. At the same time, after the cockpit roof 20 contacts the side guardrail 23, it can form an activity space above the driver, preventing the driver from being numb in the narrow escape space and unable to escape in time.

[0037] When the mine collapses, the collapsed material falls onto the top of the cab roof 20. The cab roof 20 is then compressed, causing the reinforcing bracket 21 to insert into the side guardrail 23. The suspension rod 19 is also driven to compress the shock-absorbing spring 15 through the trigger trapezoidal column 14. This process provides a buffer space for the cab roof 20, reducing the resonance and deformation caused by the impact of the collapsed material. When the collapsed material is too large and the shock-absorbing spring 15 cannot recover, the trigger trapezoidal column 14 can compress the limiting tongue 6. The limiting tongue 6 compresses the support spring 7 at one end, further providing a shock-absorbing effect, until the limiting tongue 6 is compressed by the trigger trapezoidal column 14 and detaches from the bottom of the seat support platform 4. After the seat carrying platform 4 loses the support of the limit latch 6, it falls along the anti-tilt suspension plate 26 into the escape cabin enclosed by the platform enclosure 9, the escape guard plate 10 and the material storage cabinet 11. At this time, the reinforcing bracket 21 is fully inserted into the side guard enclosure 23, and the driver's cabin top plate 20 can be closed with the side guard enclosure 23 to form a protective space on the driver's top. The suspension rod 19 can support the driver's cabin top plate 20 and strengthen the pressure resistance of the driver's cabin top plate 20. After the driver falls into the platform enclosure 9, he can open the cabinet enclosure 12 to obtain the escape supplies in the material storage cabinet 11. After the collapse stabilizes, the driver can open the escape protection plate 10 to escape with tools or facilitate rescue.

[0038] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
