Description

Technical Field

[0001] This invention relates to the field of vehicle wind protection technology, and in particular to a ground-mounted vehicle wind protection device. Background Technology

[0002] Large material yards are usually circular in shape and have advantages such as large storage capacity, convenient stacking, and good environmental protection. They are widely used as storage structures for bulk commodities such as coal, ore, and petroleum coke. The material piles in the material yard are generally surrounded by retaining walls and overhead cranes. The retaining walls help to increase the stacking height of the material piles, and the overhead cranes facilitate the handling of materials.

[0003] Currently, the overhead cranes used in these material yards are generally of various types, including manual pallet trucks, semi-electric pallet trucks, fully electric pallet trucks, and explosion-proof manual hydraulic pallet trucks. Parking is required during loading and unloading.

[0004] However, since some material yards are located near the riverbank where the wind is strong, vehicles are very likely to overturn when parked. This not only hinders the subsequent handling of materials but also affects the safety of workers. Therefore, this invention provides a ground-mounted windproof device for overhead vehicles. Summary of the Invention

[0005] Therefore, the technical problem to be solved by the present invention is to overcome the problem that vehicles are very likely to roll over when parked in the prior art.

[0006] To solve the above-mentioned technical problems, the present invention provides a ground-mounted windproof device for vehicles, including a vehicle frame, a plurality of vehicle wheels provided on the lower end face of the vehicle frame, wind deflectors fixedly connected to the four corners of the vehicle frame, a wind deflector plate slidably connected in each wind deflector frame, a sliding groove adapted to the wind deflector plate in the wind deflector frame, a steel wire hook rope provided at the bottom of each wind deflector plate, an adjustment mechanism provided at the four corners of the vehicle frame, the adjustment mechanism being used to drive the wind deflector plate to move up and down in the wind deflector frame, and a fastening mechanism provided below each wind deflector plate, the fastening mechanism being used to fix the steel wire hook rope.

[0007] In one embodiment of the present invention, the adjusting mechanism includes a plurality of L-shaped support rods fixed to the upper end face of the trolley frame. The plurality of L-shaped support rods and a plurality of wind deflectors are arranged in a one-to-one correspondence. Each L-shaped support rod has a winding wheel rotatably connected to its end near the wind deflector. A steel wire rope is sleeved on the outer surface of the winding wheel. The side of the steel wire rope away from the winding wheel is fixed to the upper end face of the wind deflector. The side end of the winding wheel is connected to the output end of a motor. The motor is installed inside the L-shaped support rod. During the driving process, the wind deflector is located inside the wind deflector frame.

[0008] In one embodiment of the present invention, a second steel wire rope is installed on the lower end face of each wind deflector, and a support frame is fixed to the bottom end of the second steel wire rope. The steel wire hook rope is set on the side wall of the support frame, and the fastening mechanism is set on one side of the support frame. During operation, when the steel wire hook rope is hung on the ground anchor, the second steel wire rope is set at the bottom of the wind deflector, which can facilitate the steel wire hook rope to change different angles, thereby making it easier to hook onto the ground anchor.

[0009] In one embodiment of the present invention, the fastening mechanism includes a clamping frame fixed to the side wall of the support frame. The clamping frame has a vertical groove in the vertical direction and a through groove in the horizontal direction. A column is fixed to the end of the steel wire hook rope near the clamping frame. The column and the clamping frame are both made of stainless steel. A second vertical groove is formed in the column. The shapes of the first and second vertical grooves are adapted to each other. A circular clamping post is provided in the clamping frame. The circular clamping post penetrates into the first and second vertical grooves. The shape of the circular clamping post is adapted to the shapes of the first and second vertical grooves. In the initial state, the column is not in the first vertical groove.

[0010] In one embodiment of the present invention, a pressure plate is fixedly connected to the upper end face of the circular locking post. The diameter of the pressure plate is larger than the diameter of the first vertical groove, and the outer wall of the pressure plate is provided with friction texture. The height of the circular locking post is greater than the height of the locking frame. During operation, when the circular locking post penetrates into the first and second vertical grooves, the pressure plate at the end of the circular locking post will press against the top of the support frame, thereby facilitating the fixing of the column rod in the first and second vertical grooves.

[0011] In one embodiment of the present invention, the bottom of the circular locking post is rotatably connected to two deflection shafts, and two limiting springs are fixedly connected to the outer side of the bottom of the circular locking post. The side of the two limiting springs away from the circular locking post is respectively connected to the two deflection shafts, and two limiting post plates are fixedly connected to the bottom of the circular locking post at the corresponding positions of the deflection shafts.

[0012] In one embodiment of the present invention, the distance between the two deflection shafts is less than the diameter of the first vertical groove and the second vertical groove, and the outer walls of the two deflection shafts are provided with arc edges; this design allows the deflection shafts to move down along the inner walls of the first vertical groove and the second vertical groove until they reach the bottom of the card frame and contact the bottom of the card frame.

[0013] In one embodiment of the present invention, a sealing seat is fixedly connected to the side wall of the vehicle frame near one of the windshield frames. A through groove is provided inside the sealing seat, and a slide rod is slidably connected inside the through groove. A contact point one is installed at the top of the slide rod, and a contact point two is installed at the corresponding position of the sealing seat and the contact point one. A linkage frame is fixedly connected to the outer wall of the slide rod, and the end of the linkage frame away from the slide rod is connected to the upper end face of the windshield.

[0014] In one embodiment of the present invention, a slot is provided in the through groove, and a locking rod is fixedly connected to the outer wall of the slide rod. The locking rod is slidably installed in the slot. During operation, when the slide rod moves up and down, the slide rod will simultaneously drive the locking rod to move in the slot. Under the mutual limiting of the locking rod and the slot, the contact and separation of contact one and contact two can be ensured, thereby facilitating the power-off and power-on of the vehicle.

[0015] In one embodiment of the present invention, the moving height of the linkage frame is greater than the height of the through slot, and the distance between the highest point of the linkage frame and the windshield frame is greater than the height of the through slot. This design facilitates the linkage frame to move the slide rod on one side of the sealing seat, thereby facilitating normal driving.

[0016] The technical solution of the present invention has the following advantages compared with the prior art:

[0017] The windproof device for ground-mounted vehicles described in this invention uses a motor to drive a winding wheel to rotate. The winding wheel causes the steel wire rope on its outer surface to loosen. Then, under the action of gravity, the wind deflector will move down from the wind deflector frame. Subsequently, one end of the steel wire hook rope is hung on the ground anchor. After the steel wire hook rope is fixed to the ground anchor, the winding wheel is controlled to reverse, so that the steel wire rope, the wind deflector, and the steel wire hook rope are taut. This ensures the stability of the wind deflector during use, which is beneficial to the safety when parking and prevents the vehicle from overturning.

[0018] The windproof device for ground-mounted vehicles described in this invention allows the deflection shaft to return to its initial position under the action of a limiting spring. The deflection shaft will be in an open state at the bottom of the clamping frame. When there is wind from the outside, the steel wire hook rope will be stressed, and the deflection shaft will be compressed. Under the limitation of the limiting post plate, the deflection shaft will be tightly pressed against the bottom of the clamping frame. This design ensures that the circular clamping post is always within the vertical groove one and vertical groove two, avoiding the problem of the circular clamping post detaching from the vertical groove one and vertical groove two due to excessive external wind force, thus improving the stability of the windproof plate and the steel wire hook rope when subjected to wind force.

[0019] The windproof device for ground-mounted vehicles described in this invention allows for the following steps when the vehicle needs to be driven again: remove the circular locking post, then remove the steel wire hook from the ground anchor, returning the wind deflector to its initial position. This re-engages contacts one and two, energizing the vehicle's circuit breaker and allowing the vehicle to continue driving. This design integrates the wind deflector and the circuit breaker, preventing operators from forgetting to remove the windproof cable and potentially damaging the equipment, thus improving driving safety.

[0031] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments described are not intended to limit the present invention.

[0032] Reference Figures 1 to 9As shown in the embodiment of the present invention, a ground-mounted windproof device for a vehicle includes a vehicle frame 1. Multiple vehicle wheels are provided on the lower end face of the vehicle frame 1. Windshield frames 2 are fixedly connected to each of the four corners of the vehicle frame 1. A windshield plate 3 is slidably connected within each windshield frame 2. A sliding groove adapted to the windshield plate 3 is provided within the windshield frame 2. A steel wire hook rope 301 is provided at the bottom of each windshield plate 3. An adjustment mechanism is provided at each of the four corners of the vehicle frame 1 to drive the windshield plate 3 to move up and down within the windshield frame 2. A fastening mechanism is provided below each windshield plate 3 to fix the steel wire hook rope 301.

[0033] During operation, the specific operation mode of the overhead crane 1 is based on existing technology and will not be elaborated upon in this embodiment. After the overhead crane 1 moves to a suitable position and stops, the wind deflector 3 is pulled out from the wind deflector frame 2 and hung on the ground anchor by one end of the wire hook rope 301. The wire hook rope 301 is fixed by the fastening mechanism, and the wind deflector 3 is fixed by the adjustment mechanism. This achieves the fixation of a single wind deflector 3. The operation mode of the wind deflectors 3 in other positions is the same. This design not only improves the safety after parking and effectively prevents typhoons, but also allows the wind deflector 3 to be retracted when not in use, saving the storage space of the wind deflector 3, which is beneficial for driving and avoids the problem of vehicle rollover.

[0034] The adjustment mechanism includes multiple L-shaped support rods 4 fixed to the upper surface of the crane frame 1. The multiple L-shaped support rods 4 and multiple wind deflectors 3 are arranged in a one-to-one correspondence. Each L-shaped support rod 4 has a winding wheel 5 rotatably connected to its end near the wind deflector 3. A steel wire rope 6 is sleeved on the outer surface of the winding wheel 5. The side of the steel wire rope 6 away from the winding wheel 5 is fixed to the upper surface of the wind deflector 3. The side end of the winding wheel 5 is connected to the motor output end, and the motor is installed inside the L-shaped support rod 4. During operation, the wind deflector 3 is located within the wind deflector frame 2. Inside; after the vehicle is parked, the winding wheel 5 is rotated by the control motor, and the steel wire rope 6 on its outer surface is released by the winding wheel 5. Then, under the action of gravity, the wind deflector 3 will move down from the wind deflector frame 2. Then, one end of the steel wire hook rope 301 can be hung on the ground anchor. After the steel wire hook rope 301 is fixed to the ground anchor, the winding wheel 5 is controlled to reverse so that the steel wire rope 6, the wind deflector 3 and the steel wire hook rope 301 are taut, ensuring the stability of the wind deflector 3 during use and facilitating safety when parking.

[0035] Each of the wind deflectors 3 has a steel wire rope 7 installed on its lower end face. The bottom end of the steel wire rope 7 is fixed to a support frame 8. The steel wire hook rope 301 is set on the side wall of the support frame 8. The fastening mechanism is set on one side of the support frame 8. During operation, when the steel wire hook rope 301 is hung on the ground anchor, the steel wire rope 7 is set at the bottom of the wind deflector 3, which makes it easy for the steel wire hook rope 301 to change different angles, thus making it easier to hook onto the ground anchor.

[0036] The fastening mechanism includes a clamping frame 9 fixed to the side wall of the support frame 8. The clamping frame 9 has a vertical groove 10 in the vertical direction and a through groove 11 in the horizontal direction. A column rod 12 is fixed to the end of the wire hook rope 301 near the clamping frame 9. Both the column rod 12 and the clamping frame 9 are made of stainless steel. A second vertical groove 121 is formed inside the column rod 12. The shapes of the first vertical groove 10 and the second vertical groove 121 are compatible. A circular clamping post 13 is provided inside the clamping frame 9, penetrating into the first vertical groove 10 and the second vertical groove 121. The shape of the circular clamping post 13 is compatible with the shapes of the first vertical groove 10 and the second vertical groove 121. In the initial state, the column rod 12 is not in the first vertical groove 10. During operation, when the wire hook rope 301 is hooked on the ground anchor, if... Figure 4 and Figure 5 As shown, the post 12 at the other end of the wire hook rope 301 passes through the through groove 11 and is placed in the clamping frame 9. Then, the circular clamping post 13 is inserted into the vertical groove 10 and passes through the vertical groove 121 on the surface of the post 12 until the bottom of the clamping frame 9. At this time, the wire hook rope 301 can be fixed to one side of the support frame 8, that is, fixed to the ground anchor. Then, the above-mentioned winding wheel 5 is reversed to make the wire hook rope 301 taut, ensuring that the wind deflector 3 is stable when subjected to wind pressure.

[0037] A pressure plate 14 is fixed to the upper end face of the circular locking post 13. The diameter of the pressure plate 14 is larger than the diameter of the vertical groove 10. The outer wall of the pressure plate 14 is provided with friction texture. The height of the circular locking post 13 is greater than the height of the locking frame 9. During operation, when the circular locking post 13 penetrates into the vertical groove 10 and the vertical groove 121, the pressure plate 14 at the end of the circular locking post 13 will press on the support frame 8, thereby facilitating the fixing of the column rod 12 in the vertical groove 10 and the vertical groove 121.

[0038] The bottom of the circular locking post 13 is rotatably connected to two deflection shafts 15. Two limiting springs 16 are fixedly connected to the outer side of the bottom of the circular locking post 13. The side of each limiting spring 16 away from the circular locking post 13 is connected to one of the two deflection shafts 15. Two limiting plates 131 are fixedly connected to the bottom of the circular locking post 13 at positions corresponding to the deflection shafts 15. During operation, in the initial state, the two deflection shafts 15 are close to each other. When the circular locking post 13 passes through the vertical groove 10 and the vertical groove... When the deflection shaft 15 is inside the second groove 121, its outer wall will contact the inner wall of the first groove 10 and the second groove 121, causing the deflection shaft 15 to be under pressure and compress the limiting spring 16. At this time, the deflection shaft 15 will contact the outer wall of the circular locking post 13. When the bottom of the circular locking post 13 passes through the first groove 10 at the bottom of the locking frame 9, that is, when the deflection shaft 15 passes through the bottom first groove 10, the deflection shaft 15 will no longer be under the pressure of the first groove 10. Under the action of the limiting spring 16, the deflection shaft 15 will return to its initial position. Figure 6 , Figure 7 and Figure 8 As shown, the deflection shaft 15 is in an open state at the bottom of the clamping frame 9. When there is wind in the outside, the wire hook rope 301 is subjected to force, and the deflection shaft 15 will be compressed. Under the limit of the limiting post plate 131, the deflection shaft 15 will be pressed tightly against the bottom of the clamping frame 9. This design can ensure that the circular clamping post 13 is always in the vertical groove 10 and the vertical groove 2 121, avoiding the problem of the circular clamping post 13 detaching from the vertical groove 10 and the vertical groove 2 121 due to excessive external wind force, thus improving the stability of the wind baffle 3 and the wire hook rope 301 when subjected to wind force.

[0039] The distance between the two deflection shafts 15 is less than the diameter of the first vertical groove 10 and the second vertical groove 121. The outer walls of the two deflection shafts 15 are provided with arc edges. This design allows the deflection shafts 15 to move down along the inner walls of the first vertical groove 10 and the second vertical groove 121 until they reach the bottom of the frame 9 and contact the bottom of the frame 9.

[0040] When it is necessary to remove the circular locking post 13, simply move the circular locking post 13 down, and the operator manually rotates the deflection shaft 15 so that the length between the two deflection shafts 15 is less than the length of the vertical groove 10. Then, the circular locking post 13 can be pulled up.

[0041] A sealing seat 17 is fixedly connected to the side wall of the crane frame 1 near one of the wind deflectors 2. A through groove 18 is formed inside the sealing seat 17, and a slide rod 19 is slidably connected inside the through groove 18. A contact point 20 is installed at the top of the slide rod 19, and a contact point 21 is installed at the corresponding position of the sealing seat 17 and contact point 20. A linkage frame 22 is fixedly connected to the outer wall of the slide rod 19, and the end of the linkage frame 22 away from the slide rod 19 is connected to the upper surface of the wind deflector 3. Contact point 21 is connected to the crane's closing switch via a power supply and a controller. During operation, when the wind deflector 3 is not removed from the wind deflector 2, i.e., in the initial state, contact point 20 and contact point 21 are in contact, and the crane is in normal driving condition, i.e., not interrupted. When the wind deflector 3 moves down from the wind deflector frame 2, the wind deflector 3 will drive the slide rod 19 down through the linkage frame 22. The slide rod 19 will cause the upper contact point 20 to disengage from the contact point 21, at which time the vehicular braking switch will be de-energized. When the vehicle needs to be driven again after parking once, the same operation is performed. The circular locking post 13 is removed, and then the wire hook rope 301 is removed from the ground anchor, so that the wind deflector 3 returns to its initial position, that is, the contact point 20 and contact point 21 are brought into contact again, so that the vehicular braking switch is energized, and the vehicle can continue to move. Through this design, the wind deflector 3 and the vehicular braking switch are combined together, which can prevent the operator from forgetting to remove the windproof cable when driving, which may cause damage to the equipment, thus improving driving safety.

[0042] A slot 181 is provided in the through groove 18, and a locking rod 191 is fixedly connected to the outer wall of the slide rod 19. The locking rod 191 is slidably installed in the slot 181. During operation, when the slide rod 19 moves up and down, the slide rod 19 will simultaneously drive the locking rod 191 to move in the slot 181. Under the mutual limiting of the locking rod 191 and the slot 181, the contact and separation of contact 1 20 and contact 2 21 can be ensured, thereby facilitating the power-off and power-on of the vehicle.

[0043] The moving height of the linkage frame 22 is greater than the height of the through groove 18, and the distance between the highest point of the linkage frame 22 and the windshield frame 2 is greater than the height of the through groove 18. This design allows the linkage frame 22 to easily move the slide rod 19 on one side of the sealing seat 17, thus facilitating normal driving.

[0044] During operation, after the crane frame 1 moves to a suitable position and stops, the wind deflector 3 is pulled out from the wind deflector frame 2 and hooked onto a ground anchor via a wire hook rope 301. The wire hook rope 301 is then secured by a fastening mechanism, and the wind deflector 3 is fixed by an adjustment mechanism. This process secures a single wind deflector 3. The operation of the wind deflectors 3 at other locations is similar. This design not only improves safety after parking and effectively prevents typhoon damage, but also allows the wind deflector 3 to be retracted when not in use, saving space. The space is designed to facilitate driving. After the vehicle is parked, the motor drives the winding wheel 5 to rotate, which causes the steel wire rope 6 on its outer surface to loosen. Then, under the action of gravity, the windshield 3 will move down from the windshield frame 2. Then, one end of the steel wire hook rope 301 can be hung on the ground anchor. After the steel wire hook rope 301 is fixed to the ground anchor, the winding wheel 5 is controlled to reverse so that the steel wire rope 6, the windshield 3 and the steel wire hook rope 301 are taut, ensuring the stability of the windshield 3 during use and improving safety when parking.

[0045] When the wire hook rope 301 is attached to the ground anchor, as Figure 4 and Figure 5 As shown, the other end of the wire hook rope 301, the post 12, passes through the through groove 11 and is placed inside the clamping frame 9. Then, the circular clamping post 13 is inserted into the vertical groove 10, passing through the vertical groove 121 on the surface of the post 12 until it reaches the bottom of the clamping frame 9. At this point, the wire hook rope 301 can be fixed to one side of the support frame 8, that is, fixed to the ground anchor. Then, by reversing the winding wheel 5 as described above, the wire hook rope 301 is taut, ensuring that the wind deflector 3 is stable when subjected to wind pressure. In the initial state, the two deflection shafts 15 are close to each other. In the first state, when the circular locking post 13 passes through the vertical groove 10 and the second vertical groove 121, the outer wall of the deflection shaft 15 will contact the inner wall of the vertical groove 10 and the second vertical groove 121, causing the deflection shaft 15 to be under pressure and squeeze the limiting spring 16. At this time, the deflection shaft 15 is in contact with the outer wall of the circular locking post 13. When the bottom of the circular locking post 13 passes through the vertical groove 10 at the bottom of the frame 9, that is, when the deflection shaft 15 passes through the bottom vertical groove 10, the deflection shaft 15 is no longer under the pressure of the vertical groove 10. Under the action of the limiting spring 16, the deflection shaft 15 will return to its initial position. Figure 6 , Figure 7 and Figure 8As shown, the deflection shaft 15 is in an open state at the bottom of the clamping frame 9. When the outside wind causes the wire hook rope 301 to be under force, the deflection shaft 15 will be compressed. Under the limit of the limiting post plate 131, the deflection shaft 15 will be pressed tightly against the bottom of the clamping frame 9. This design can ensure that the circular clamping post 13 is always in the vertical groove 10 and the vertical groove 2 121, avoiding the problem that the circular clamping post 13 will be dislodged from the vertical groove 10 and the vertical groove 2 121 due to excessive external wind force, thus improving the stability of the wind baffle 3 and the wire hook rope 301 when subjected to wind force.

[0046] When the wind deflector 3 is not removed from the wind deflector frame 2, i.e., in the initial state, contact 1 20 and contact 2 21 are in contact, and the vehicle is in normal driving condition, i.e., not powered off. When the wind deflector 3 moves down from the wind deflector frame 2, the wind deflector 3 will drive the slide rod 19 down through the linkage frame 22. The slide rod 19 will cause the upper contact 1 20 to disengage from the contact 2 21, and the vehicle's closing switch will be de-energized. When the vehicle needs to be driven again after parking once, the same operation is performed. The circular locking post 13 is removed, and then the wire hook rope 301 is removed from the ground anchor, so that the wind deflector 3 returns to its initial position, i.e., it causes contact 1 20 and contact 2 21 to contact again, so that the vehicle's closing switch is energized. Only in this way can the vehicle continue to move. Through this design, the wind deflector 3 and the vehicle's closing switch are combined together, which can prevent the operator from forgetting to remove the windproof cable when driving, which could damage the equipment and improve driving safety.

[0047] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
