Aiming at the problems of high cost and large investment of a hollow iron rail in the prior art and inconvenience in providing power for a vehicle body, the invention provides a connecting structure of a hollow iron driving end, and the connecting structure realizes the driving of a hollow iron operation process by a rail and a power mechanism which are connected with each other. The rails comprise top plates and bottom plates which are parallel to each other, the top plates are used for being fixed below municipal facilities such as various overhead bridges and the like, the bottom plates are lifted through the partition plates to be hung, and the top plates and the bottom plates are connected into an integral structure through the partition plates, so that the integrity of the rail is ensured. The fixing between the top plate and the installation station is carried out through the top plate, and the top plate can be stably connected with the installation station due to the large contact surface of the top plate, such as a large-scale anchoring mode, so that the installation stability of the whole track is ensured. Meanwhile, the top plate can be sufficiently connected with the partition plate, so that the distortion of the track at the turning position is avoided, even if a large centrifugal force is applied to the partition plate at the turning position by the empty iron car body, the partition plate can also integrally transfer stress to the top plate for dispersion, and therefore the internal stress of the partition plate is greatly reduced, and the stress of the partition plate is ensured to be uniform and stable. The bottom plate is used for bearing the weight of the whole hollow iron and simultaneously providing a motion track for the hub motor of the hollow iron. In order to improve the structural strength and the bearing performance of the bottom plate and the anti-pressing capacity of the bottom plate, a plurality of reinforcing ribs are uniformly arranged at the bottom of the bottom plate, and further support and reinforcement are provided for the bottom plate so as to ensure that the bottom plate supports the whole empty iron car body. The two mounting blocks are opposite to each other and are used for being connected to the left side and the right side of the top of the empty iron car body, and through holes are formed in the mounting blocks. Two in-wheel motors are located the top of two installation pieces, and an in-wheel motor is connected with an installation piece. The connection between the hub motor and the mounting block is realized through the connecting rod and the bearing block, wherein the connecting rod is directly connected with the stator of the hub motor, so that the hub motor can independently rotate on the connecting rod to provide power for the empty iron. The axis of the hub motor is parallel to the connecting line of the two through holes so as to ensure that the rotating surface of the hub motor is carried out along the advancing direction of the empty iron car body and ensure that the invention stably outputs power. The connecting rod is located one side that one wheel hub motor kept away from another wheel hub motor, is for the inboard in the middle of two wheel hub motors promptly, and the connecting rod is connected in wheel hub motor's outside to ensure to have sufficient clearance space between two wheel hub motors, the baffle can be located between two wheel hub motors. The bearing block is located the one end that the connecting rod kept away from in-wheel motor, and the bearing block stretches into in the through-hole that corresponds from the outside of installation piece, and wherein the outside of installation piece just means two installation pieces that are just opposite each other one side that the installation piece kept away from each other for the bearing block can not cause influence and interference to the region between two installation pieces. The elastic piece is arranged in each through hole, one end of the elastic piece is fixed on the bearing block, and the other end of the elastic piece is fixed on the top surface of the through hole, so that the installation block is connected with the bearing block through the elastic piece, indirect connection between the installation block and the hub motor is realized, namely, efficient connection between the empty iron car body and the hub motor serving as a power mechanism is realized.
The invention has simple structure, and can realize the transverse stability of the hollow iron by simultaneously connecting the two mounting blocks on the left side and the right side of the top of the hollow iron body, and the weight of the hollow iron is sequentially transmitted to the bearing blocks, the connecting rods and the hub motors through the mounting blocks, and the two hub motors move on the bottom plate, so that the bottom plate supports the weight of the body. The hub motor rolls on the bottom plate to drive the lower mounting block to move along the track, so as to drive the empty iron car body connected to the mounting block to move. The elastic piece plays a role in vibration reduction and shock resistance in the longitudinal direction, and the traditional mode of directly sleeving the damping spring cannot be directly used in the hollow iron due to the particularity of the hollow iron hanging in the air, otherwise, the self weight of the hollow iron can cause the damping spring to fail rapidly, and any damping effect cannot be achieved. In order to overcome the problem, the elastic member for shock absorption in the present invention is realized in a reverse connection manner, and in particular, since the hub motor rolls on the track, the connecting rod and the bearing block connected with the hub motor are relatively fixed, so that the lower end of the elastic member, i.e., the end connected with the bearing block is relatively fixed, and deformation is not generated from the end. The gravity of the empty iron car body directly acts on the mounting block, the mounting block always receives extremely large downward pulling force, so the upper end of the elastic piece, namely one end connected to the top surface of the through hole, is always pulled down along with the mounting block, in the process, the empty iron gravity acts on the elastic piece, so that the elastic piece is always in a compressed state, but not in a stretched state after being connected in a traditional damping mode, and the elastic piece is free from the problem of stretching failure, and can always provide the capacity of stretching and resetting. When the hollow iron shakes downwards, the elastic piece is further compressed, so that the provided elastic restoring force is increased, and the downward shaking amplitude of the hollow iron is reduced; when the empty iron shakes upwards, the pressure born by the elastic piece is reduced, the elastic piece is properly stretched and reset, so that the upward thrust of the elastic piece to the mounting block time is reduced, the upward component force born by the mounting block is reduced, the upward movement acceleration of the mounting block is obviously reduced, and the upward shaking amplitude of the empty iron can be reduced. Therefore, the invention solves the problems that the traditional damping structure can be quickly invalid and has no damping effect when being used in the air iron by the reversely connected elastic piece, and can play an extremely excellent damping effect on the upward or downward shaking of the air iron. When the invention is particularly used, the empty iron car body is positioned below the bottom plate, and only energy is provided to enable the two hub motors to rotate, the hub motors roll on the bottom plate along the bottom plate, so that the empty iron car body can be driven to move. In addition, as a person skilled in the art, a guiding groove matched with the hub motor and the like can be arranged on the bottom plate to increase the guiding of the hub motor. Compared with the prior art, the invention has the advantages that the structure is greatly simplified, if the top plate, the bottom plate and the partition plate are regarded as a whole to form an H-shaped structure, so that the common H-shaped steel can be used as the main body of the air rail, and the air rail is provided with the reinforcing ribs, thereby not only having simple production and manufacture, low cost and convenient maintenance, but also having outstanding significance for the excessive industry of steel industry. By carrying out finite element analysis on the invention, the strength and deformation of the track under the dead weight and the vehicle-mounted condition can be clearly obtained, and the load requirement required by hanging the empty iron can be completely met. Therefore, the invention solves the problems of high cost and large investment of the hollow iron rail in the prior art, and realizes the purpose of remarkably reducing the cost of the hollow iron rail while meeting the strength requirement.
Preferably, a leaf spring is also connected between the two mounting blocks. The plate spring has the characteristics of high strength and high rigidity, so that the plate spring is further connected between the two mounting blocks, the damping effect can be further improved, the stability in the running process of the blank iron is improved, and the long-term effective work of the damping device can be ensured.
Preferably, the plate spring comprises an upper reed and a lower reed which are distributed up and down, and the upper reed and the lower reed are opposite to each other. The upper reed and the lower reed are opposite to each other, so that the upper reed is positioned above the lower reed, and the upper reed and the lower reed are mutually extruded and deformed, so that a large amount of elastic restoring force can be provided, the vibration reduction effect on the vehicle body vibration in the longitudinal direction is further improved, and the vehicle body stability in the running process of the air iron is greatly improved.
Further, two ends of the upper reed are respectively fixed on the top surfaces of the two through holes, and two ends of the lower reed are respectively fixed on the two bearing blocks; and two ends of the elastic piece are respectively connected with the upper reed and the lower reed. In the scheme, both ends of the upper reed and the lower reed are positioned in the through holes, and the two mounting blocks can be connected through the upper reed and the lower reed, so that the structural integrity and the stability of internal stress distribution of the invention are improved. Simultaneously, the two bearing blocks are connected through the lower reed, so that the two connecting rods are relatively fixed, the relative distance between the two hub motors is ensured to be stable all the time, the transverse shaking amplitude of the hollow iron is reduced, and the transverse stability of the hollow iron is greatly improved. Particularly, when the empty iron turns, the vehicle body rotates along with the track, and due to the combined action of centrifugal force and gravity, the two bearing blocks are very easy to be mutually close or far away, and although the bearing blocks are limited by the hub motor with relatively stable upper part, the mounting blocks connected with the bearing blocks can be laterally displaced or inclined and react on the vehicle body to be laterally swaying of the vehicle body, so that the invention fixes the two bearing blocks through the lower reed, thereby overcoming the problems and greatly improving the lateral stability of the empty iron in the running process of the vehicle body.
Preferably, wear-resistant strips are arranged at the bottom of the upper reed and the top of the lower reed. The abrasion between the upper reed and the lower reed is reduced, and the upper reed and the lower reed body are fully protected by the wear-resistant strip. The wear-resistant strip is preferably an alloy strip with the thickness of 1-2 cm.
Preferably, the upper reed and the lower reed are arc-shaped plates, the upper reed protrudes towards the lower reed, and the lower reed protrudes towards the upper reed. In the scheme, the upper reed and the lower reed are mutually extruded to generate deformation, so that vibration generated by a vehicle body or an in-wheel motor is absorbed and buffered, excellent damping performance is ensured, and meanwhile, the structural strength of the automobile is improved, and the service life is prolonged.
Preferably, the device further comprises a suspension plate fixedly connected below the two mounting blocks, and the suspension plate is used for connecting an empty railway vehicle body. This scheme is realized jointly to empty indisputable automobile body by two installation piece cooperation suspension boards, and suspension board's existence can make the stress point enlarge for whole structure atress is more even, avoids the installation piece lug connection automobile body to lead to the too weak problem of tie point.
Preferably, the reinforcing ribs are distributed at equal intervals along the length direction of the bottom plate; the partition plate penetrates through the bottom plate from top to bottom, the part of the partition plate penetrating through the bottom plate is an extension part, and the reinforcing ribs are fixed on two sides of the extension part. The length direction of the bottom plate is the length direction of the track, so that for empty iron in operation, the equal-spacing distribution of the reinforcing ribs is in the operation direction, the load borne by the bottom plate can be always shared by the reinforcing ribs which continuously and alternately appear, the internal stress distribution in the bottom plate is ensured to be uniform, the deformation of the bottom plate after the bottom plate is instantaneously pulled is further reduced, and the reactive force is provided for the bottom plate through the reinforcing ribs, so that the instantaneously deformed bottom plate can instantaneously reset after the load disappears. The reinforcing ribs are divided into two parts distributed along the left side and the right side of the bottom plate through the extending parts, so that loads applied to the bottom plate by the hub motors positioned on the two sides of the partition plate can be borne by the reinforcing ribs on the two sides of the extending parts respectively, compared with the integral reinforcing rib arrangement, the material consumption and the cost saving of the reinforcing ribs can be reduced, and meanwhile, the bending resistance and the twisting resistance are greatly improved due to the fact that the length of the single reinforcing rib is reduced. In addition, for the setting of integral strengthening rib, the strengthening rib both ends receive extremely big load to produce the whereabouts deformation and the middle part hardly receives longitudinal force, this just makes the strengthening rib become flexible to drop easily even take place the distortion, and through the setting in this scheme, the internal stress distribution compact even of monolithic strengthening rib, bear also very even stable, consequently the life of strengthening rib has improved by a wide margin.
Preferably, the reinforcing ribs are right triangles, and two right-angle sides of the right triangles are respectively fixed on the bottom surface of the bottom plate and the side surface of the extension part; and two acute angles of the right triangle are respectively flush with the outer edges of the bottom plate and the extension part. In this scheme, provide more stable connection station for the strengthening rib through extension, avoid the strengthening rib to be connected with the bottom plate through a side only and lead to the relatively poor problem of stability for the both sides limit of strengthening rib can both be connected. Meanwhile, the right triangle-shaped reinforcing rib structure enables the center line part of the bottom plate to be supported by the thickest parts of the reinforcing ribs at the two sides, and provides great protection for the center line part of the bottom plate, so that the problem that the middle part starts to distort first due to the fact that the two ends of the bottom plate are subjected to great load applied by the hub motor is avoided, and the whole structure has extremely high overall stability.
Preferably, the top plate and the bottom plate are both arc-shaped and arched upwards, and the arc radiuses of the top plate and the bottom plate are R meters, wherein R is more than or equal to 700 and less than or equal to 800. In the running process of the blank iron, great tension can be generated on the rail on the upper part of the blank iron, and in the process, the bottom plate and the top plate can generate tiny deformation. When the empty iron passes through quickly, the deformation can be reset quickly, but when the empty iron stays at a certain place for too long, the deformation of the small downward bending which is not easy to recover is caused, and the deformation can not cause safety accidents for normal operation of the empty iron, but can aggravate abrasion and energy loss in the operation of the empty iron, so that the energy consumption is larger and the maintenance is more frequent. This scheme just sets up in order to overcome this kind of problem, all set up the circular-arc that upwards arches of equidistant with roof and bottom plate, in the place that does not produce deformation, the sky iron operation is in the process of going up slope downhill path in proper order, though the in-process energy consumption of going up slope increases, but the downhill path energy consumption reduces, consequently, the energy consumption remains unchanged basically as a whole, simultaneously this kind of structure of pre-arching can effectively offset orbital downwarping, make the track after slight deformation tend to the level, be favorable to the steady of sky iron to pass through, the region of every entering a track of sky iron just pulls down this root track to tend to the level, thereby make the track in the operation of having sky iron be in a very little but beneficial in-process of horizontal in proper order, make the track can produce self-adaptation effect to sky iron, very big improvement the stability in the operation of sky iron. The radius of the arc is R m, wherein R is more than or equal to 700 and less than or equal to 800. In this range, for a track of several meters or tens of meters, the central angle range is extremely small, and only a few tenths to a few degrees are provided, so that the track is convenient to offset tiny invisible sag deformation generated by the track when the track passes through empty iron, the whole track is connected by arcs in sequence, but is completely invisible to naked eyes, and any uncomfortable feeling is not generated for passengers, so that riding experience can be effectively improved.
