Description

Technical Field

[0001] This invention relates to the field of mining truck cab structure technology, and in particular to a high-safety torsional-resistant structure for a mining truck cab. Background Technology

[0002] The driver's cab of a mining car is the main working area where the driver operates and controls the vehicle (such as a mining transport car). Mining cars are commonly found in mines, quarries, and open-pit mines, used to transport heavy materials such as ore, coal, and building materials. Because mining cars operate in harsh terrain and working environments, the design of the driver's cab must consider comfort, safety, and functionality to ensure that the driver can maintain a stable working state during long-term, high-load operations and to cope with sudden changes in terrain and potential safety risks.

[0003] The high-safety torsional resistance structure of the mine car cab is designed to ensure the safety of the driver in the harsh environment of the mining area, especially when the mine car travels over uneven or steep terrain or in the event of an accident such as a rollover. This design typically includes enhancing the cab's torsional resistance, impact resistance, and overall strength, thereby ensuring that the cab can withstand various stresses and impacts from the mine car in complex terrain.

[0004] Due to the poor road conditions in mining areas, the risk of mine cars tipping over when traveling on uneven or poor-quality surfaces is a serious safety hazard, especially during transportation. When a mine car tilts or tipps over, it threatens the driver's safety and can also cause damage to the car and loss of cargo. Most mine car cab designs do not consider driver protection when the car tilts. If the car tilts or overturns, the driver may not be effectively protected. Existing cabs mostly use simple steel frame structures, which can prevent impact to some extent, but may not provide sufficient support and cushioning if the car tilts or overturns significantly.

[0005] In summary, the existing technology lacks an automated anti-tipping technology for the cab of a mining truck. Summary of the Invention

[0006] The purpose of this invention is to address the shortcomings of the prior art by proposing a high-safety torsion-resistant structure for a mining truck cab.

[0007] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a high-safety anti-torsion structure for a mine car cab, comprising a mine car body, a cab base fixedly mounted on the mine car body, a plurality of reinforcing columns fixedly connected to the cab base, a cab top mount fixedly connected to the reinforcing columns, a plurality of motor mounts fixedly connected to the cab top mount, wherein a retraction mechanism is rotatably connected to two of the reinforcing columns, a movable frame is rotatably connected to the retraction mechanism, an anti-tipping mechanism is slidably fitted within the movable frame, and a transmission mechanism is rotatably connected within the movable frame.

[0008] Preferably, the motor base has multiple guide rods connected and fixed in a ring structure. A mounting base is slidably fitted onto each guide rod. A shock-absorbing spring is fixedly connected to both the upper and lower ends of the mounting base that slidably fits with the guide rod. A motor is fixedly mounted on the mounting base. A drive shaft is fixedly connected to the output end of the motor. A protective cover is provided above the motor base. The protective cover slidably fits with the guide rods. A limit pin is slidably fitted onto the protective cover, and the limit pin is in movable contact with one of the guide rods.

[0009] Preferably, the retracting mechanism includes a worm A with two worm teeth in opposite directions of rotation. The worm A is rotatably connected to a reinforcing column, and a transmission sleeve is fixedly connected to the top end of the worm A. The inner wall of the transmission sleeve is slidably fitted with the outer wall of the transmission shaft.

[0010] Preferably, two worm wheels A are meshed and driven on one side of the worm gear A. The worm wheel A is rotatably connected to the reinforcing column via a pin. A take-up and release rod assembly is fixedly connected to the worm wheel A. The other end of the take-up and release rod assembly is rotatably connected to the moving frame. An arc-shaped rack is fixedly connected to the end of the take-up and release rod assembly near the moving frame.

[0011] Preferably, the anti-tipping mechanism includes a support column, which is slidably fitted with the inner wall of the movable frame. A fixed support seat is fixedly connected to the bottom end of the support column, and a movable support seat is rotatably connected to the fixed support seat. A serrated plate is connected to one side of both the fixed support seat and the movable support seat.

[0012] Preferably, a universal joint A is rotatably connected to the inner wall of one side of the fixed support base. One end of the universal joint A is fixedly connected to the movable support base, and the other end of the universal joint A is fixedly connected to a worm gear B. A worm B is meshed and driven on one side of the worm gear B. The worm B is rotatably connected to the inner wall of the fixed support base, and an adjusting wheel is fixedly connected to one end of the worm B.

[0013] Preferably, a fixed rack is fixedly connected to the bottom end of the movable frame, and the fixed rack is engaged with the adjusting wheel for transmission.

[0014] Preferably, the transmission mechanism includes a universal joint B, with both ends of the universal joint B rotatably connected to the inner wall of the movable frame. One end of the universal joint B is fixedly connected to a threaded rod, which is threadedly connected to a support column. The other end of the universal joint B is fixedly connected to a rotating shaft, on which a transmission wheel is fixedly connected. The transmission wheel meshes with an arc-shaped rack for transmission.

[0015] Preferably, reinforcing ribs are fixedly connected to both the upper and lower ends of the reinforcing column, and the reinforcing ribs are fixedly connected to the cab base and the cab top seat respectively.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. During the use of mine cars, by setting up an anti-tipping mechanism, when the mine car tilts too much, the support column drives the fixed support seat to move down to support the mine car. This can effectively avoid the danger of the mine car overturning or tilting too much, protect the life and safety of miners and the safety of operation, effectively improve the stability of the mine car in complex working environments, reduce the risk of accidents, and ensure the safety and efficiency of mining operations.

[0018] 2. By setting up movable support seats, the support area can be increased, which can effectively distribute the weight of the vehicle, reduce the pressure brought by single-point support, and avoid vehicle overturning caused by overload of support points. The large support area helps to reduce the ground pressure at the support point, especially on soft or uneven ground, and can prevent the support seats from sinking into mud or gravel. By increasing the support area, the tilt tolerance of the mine car can be improved, preventing the mine car from overturning on steep slopes or uneven roads, and reducing accidents caused by overturning. By setting up an adjustment mechanism, the movable frame can be retracted and extended. When the mine car is driving normally or stopped, the support frame can be retracted to avoid occupying too much space and affecting the transport capacity of the mine car. When support is needed, the support frame will automatically extend without occupying extra space.

[0019] 3. By installing reinforcing ribs on the reinforcing columns, the torsional strength of the cab can be improved, which can significantly enhance the structural strength of the cab, reduce twisting or deformation caused by external forces, and ensure the safety of the personnel in the cab. By installing shock-absorbing springs and protective covers, shock absorption and protection of the motor can be achieved, ensuring its service life under the harsh conditions of the mining area.

[0029] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0030] like Figures 1-8The diagram shows a high-safety anti-torsion structure for a mine car cab, comprising a mine car body 1, a cab base 2 fixedly mounted on the mine car body 1, multiple reinforcing columns 3 fixedly connected to the cab base 2, a cab top seat 4 fixedly connected to the reinforcing columns 3, and multiple motor seats 5 fixedly connected to the cab top seat 4. A retraction mechanism 6 is rotatably connected within two reinforcing columns 3, a movable frame 7 is rotatably connected to the retraction mechanism 6, an anti-tipping mechanism 8 is slidably fitted within the movable frame 7, and a transmission mechanism 9 is rotatably connected within the movable frame 7.

[0031] like Figure 5 As shown, multiple guide rods 501 are fixedly connected in a ring structure on the motor base 5. A mounting base 502 is slidably fitted onto each guide rod 501. Shock-absorbing springs 503 are fixedly connected to both the upper and lower ends of the mounting base 502, which is slidably fitted onto the guide rods 501. A motor 504 is fixedly mounted on the mounting base 502. A drive shaft 505 is fixedly connected to the output end of the motor 504. A protective cover 506 is provided above the motor base 5. The protective cover 506 is slidably fitted onto the guide rods 501. A limit pin 507 is slidably fitted onto the protective cover 506, and the limit pin 507 is in movable contact with one of the guide rods 501. By pushing the protective cover 506 upwards and then pushing the limit pin 507 inwards, the limit pin 507 blocks the upper side of the guide rod 501, keeping the protective cover 506 in an open state, facilitating maintenance of the motor 504 on the mounting base 502.

[0032] like Figure 6 As shown, the take-up and release mechanism 6 includes a worm gear A601 with two worm teeth in opposite directions. The worm gear A601 is rotatably connected to the reinforcing column 3. A transmission sleeve 602 is fixedly connected to the top of the worm gear A601. The inner wall of the transmission sleeve 602 is slidably fitted with the outer wall of the transmission shaft 505.

[0033] Two worm gears A603 are engaged on one side of the worm gear A601. The worm gears A603 are rotatably connected to the reinforcing column 3 via pins. A take-up / release rod assembly 604 is fixedly connected to the worm gears A603. The other end of the take-up / release rod assembly 604 is rotatably connected to the moving frame 7. An arc-shaped rack 605 is fixedly connected to the end of the take-up / release rod assembly 604 closest to the moving frame 7. The motor 504 drives the transmission shaft 505 to rotate, which in turn drives the worm gear A601 connected to the transmission sleeve 602 to rotate. This causes the worm gear A601 to drive the take-up / release rod assembly 604 connected to the worm gears A603 to rotate, thus moving the moving frame 7.

[0034] like Figure 8As shown, the anti-tipping mechanism 8 includes a support column 801, which is slidably fitted to the inner wall of the movable frame 7. A fixed support base 802 is fixedly connected to the bottom end of the support column 801, and a movable support base 803 is rotatably connected to the fixed support base 802. Both the fixed support base 802 and the movable support base 803 have serrated plates 808 connected to one side. When the retractable rod assembly 604 moves the movable frame 7, the arc-shaped rack 605 connected to one end of the retractable rod assembly 604 drives the transmission wheel 904 to rotate. The transmission wheel 904 drives the rotating shaft 903 to rotate, which in turn drives the connected universal joint B901 to rotate. The universal joint B901 then drives the connected threaded rod 902 to rotate, thereby causing the support column 801 to move downward.

[0035] A universal joint A804 is rotatably connected to the inner wall of one side of the fixed support base 802. One end of the universal joint A804 is fixedly connected to the movable support base 803, and the other end of the universal joint A804 is fixedly connected to a worm gear B805. A worm B806 is engaged with one side of the worm gear B805, and the worm B806 is rotatably connected to the inner wall of the fixed support base 802. An adjusting wheel 807 is fixedly connected to one end of the worm B806. When the support column 801 moves downward, the adjusting wheel 807 rotates under the action of the fixed rack 701. At this time, the adjusting wheel 807 drives the connected worm B806 to rotate, which in turn drives the worm gear B805 to rotate. This causes the worm gear B805 to rotate, which in turn causes the movable support base 803 connected to the universal joint A804 to rotate.

[0036] like Figure 7 As shown, a fixed rack 701 is fixedly connected to the bottom end of the movable frame 7, and the fixed rack 701 is engaged with the adjusting wheel 807 for transmission.

[0037] like Figure 7 As shown, the transmission mechanism 9 includes a universal joint B901. Both ends of the universal joint B901 are rotatably connected to the inner wall of the movable frame 7. A threaded rod 902 is fixedly connected to one end of the universal joint B901. The threaded rod 902 is threadedly connected to the support column 801. A rotating shaft 903 is fixedly connected to the other end of the universal joint B901. A transmission wheel 904 is fixedly connected to the rotating shaft 903. The transmission wheel 904 meshes with the arc-shaped rack 605 for transmission.

[0038] like Figure 4 As shown, reinforcing ribs 301 are fixedly connected to both the upper and lower ends of the reinforcing column 3. The reinforcing ribs 301 are fixedly connected to the cab base 2 and the cab roof 4, respectively. The reinforcing column 3 is made of high-strength steel.

[0039] Working principle: During the use of the mine car body 1, when the tilt of the mine car body 1 is detected to be too large, the motor 504 drives the transmission shaft 505 to rotate, which in turn drives the worm gear A601 connected to the transmission sleeve 602 to rotate. The worm gear A601 then drives the take-up and release rod assembly 604 connected to the worm wheel A603 to rotate, which in turn drives the take-up and release rod assembly 604 to move the moving frame 7.

[0040] While the retractable rod assembly 604 drives the movable frame 7 to move, the arc-shaped rack 605 connected to one end of the retractable rod assembly 604 will drive the transmission wheel 904 to rotate, which will drive the rotating shaft 903 to rotate, which will drive the universal joint B901 to rotate, which will drive the threaded rod 902 to rotate, thereby driving the support column 801 to move down.

[0041] When the support column 801 moves down, the adjusting wheel 807 will rotate under the action of the fixed rack 701. At this time, the adjusting wheel 807 will drive the connected worm gear B806 to rotate, which will drive the worm wheel B805 to rotate. The worm wheel B805 will drive the movable support seat 803 connected to the universal joint A804 to flip, so that the fixed support seat 802 and the movable support seat 803 are supported on the ground to prevent the mine car body 1 from tipping over.

[0042] When it is necessary to inspect the motor 504, push the protective cover 506 upward and then push the limit pin 507 on the protective cover 506 inward so that the limit pin 507 blocks the upper side of the guide rod 501, so that the protective cover 506 remains open, which facilitates the inspection of the motor 504 on the mounting base 502.

[0043] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed invention. The scope of protection claimed by the appended claims and their equivalents is defined.
