Description

Technical Field

[0001] This invention belongs to the field of rail transportation technology, specifically relating to a double-layer fully automatic opening and closing roller beam device for subway rail transportation. Background Technology

[0002] Due to space constraints in subways, a double-layer roller beam structure is typically used when transporting subway rails. However, the common way to open roller beams on the market is to manually loosen the upper handwheel and stop in sequence, lower the spacer, rotate the roller beam 90° to the roller bracket, and lock the roller with the stop to open the roller beam. After confirming that the first layer of long rails is installed and locked in accordance with requirements, push the second layer of roller beams back to the original column, lock the roller beam with the stop, push the roller with the spacer, push the locking beam back to its original position, lock it with the stop, and close the roller beam.

[0003] Therefore, the following drawbacks exist: during rail loading and unloading operations, manual opening, closing, and locking are required, leading to inaccurate positioning, cumbersome operations, high labor intensity, and low work efficiency. Furthermore, the existing upper roller beam is a cantilever beam structure. After the upper roller beam is closed, there is still a certain gap between the upper roller beam and the transverse roller beam support platform on the side column. This gap only allows the beam to contact the carriage when placing the rails, affecting the stress on the upper roller beam and reducing its service life.

[0004] Furthermore, the bottom roller beam is directly placed on the vehicle floor and its height is fixed. Due to the shaking of the vehicle during operation, the different floor heights of the vehicles will cause gaps between some of the lower roller beams and the rails they support. Since long rail transport train sets are composed of several independent vehicles connected together, it is impossible to guarantee that the floor heights of all vehicles are completely consistent. Because the height difference always exists, vehicles with lower floor levels cannot fully support the weight of the rails, resulting in an imbalance in the gravity support of the entire rail, which is detrimental to the driving safety during rail transport. Summary of the Invention

[0005] The present invention aims to provide a double-layer fully automatic opening and closing roller beam device for subway rail transportation. The fully automatic opening and closing of the roller beam is simple to operate and solves the problems of heavy workload and low efficiency caused by manual opening, closing and locking of the roller beam, the gap between the roller beam and the transverse roller beam support platform affecting the roller beam, and the inability of vehicles with low floor levels to fully support the rails, resulting in an imbalance in the weight support of the entire rail.

[0006] Therefore, the technical solution adopted by this invention is as follows: a double-layer fully automatic opening and closing roller beam device for subway rail transportation, including an upper roller beam, a lower roller beam, a drive column, and side columns corresponding to the drive column. One end of the horizontally transverse upper roller beam is rotatably mounted on the drive column, and the other end rests on the side column. It also includes an automatic control mechanism and a roller beam rotation support mechanism located on the same longitudinal line as the drive column. The automatic control mechanism includes a control host and several position sensors mounted on the side columns and the roller beam rotation support mechanism for transmitting the position information of the upper roller beam. The sensor feedback signal is sent to the control host to automatically control the opening and closing of the upper roller beam. The lower roller beam is located between the drive column and the side column and is installed on the adjustable height bearing beam. The adjustable height bearing beam includes a bearing beam and crossbeam support feet located on the front and rear sides of the bottom of the bearing beam, as well as a crossbeam height adjustment mechanism. The crossbeam support feet include a base and a longitudinal support plate installed on the base and capable of vertical movement. The crossbeam height adjustment mechanism includes a wedge, a fixed plate with a threaded hole, and a screw that passes through the threaded hole and connects to the outside of the wedge. By rotating the screw, the wedge can be moved horizontally to adjust the overall height of the bearing beam and the lower roller beam.

[0007] As a preferred embodiment of the above scheme, the upper roller beam includes a crossbeam with a vertical rotating cylinder welded to one end and a horizontal through hole at the other end. The side column includes a side column main frame and a transverse roller beam support platform. The transverse roller beam support platform is installed at the telescopic top of the elevator, and a roller beam positioning column is provided at the center of the top of the transverse roller beam support platform, which can pass through the horizontal through hole to fix the transverse upper roller beam. Therefore, when the roller beam needs to rotate, the transverse roller beam support platform is automatically controlled to lower until the roller beam positioning column moves out of the horizontal through hole, thereby avoiding friction between the roller beam and the transverse roller beam support platform, which would affect the stress on the roller beam and reduce its service life. It also changes the stress on the roller beam from a cantilever beam to a simply supported beam, so that the roller beam is balanced in both open and closed states, and the structure is stable.

[0008] The roller beam rotation support mechanism includes a support frame, a longitudinal roller beam support plate, and a lifting column located at the center of the longitudinal roller beam support plate. When the transverse upper roller beam rotates around the vertical rotating cylinder until it rests on the longitudinal roller beam support plate, a signal is fed back to the control host through the position sensor. The lifting column automatically rises and passes through the horizontal through hole to fix the longitudinal upper roller beam, thereby locking the upper roller beam. The structure is ingeniously designed to integrate the rail bearing and locking functions.

[0009] More preferably, the drive column includes a hydraulic cylinder, the piston rod of which is connected to a vertical rotating cylinder. The vertical rotating cylinder can rotate by the piston rod, thereby driving the upper roller beam to rotate. The hydraulic drive makes the operation simple, convenient and quick.

[0010] More preferably, the drive column includes a rotating shaft placed inside the vertical rotating cylinder, a main column frame connecting the two ends of the rotating shaft, and a drive gear mounted on the drive motor. The bottom end of the vertical rotating cylinder is provided with a driven gear that meshes with the drive gear. A bearing is provided between the rotating shaft and the vertical rotating cylinder. The vertical rotating cylinder can rotate by gear transmission, thereby driving the raceway beam to rotate. The gear transmission saves installation space, has a novel design, and the components are interlocked.

[0011] Further preferably, the lower part of the rotating shaft is provided with a convex ring, and both the upper and lower ends of the vertical rotating cylinder are provided with caps. The cap at the lower end abuts against the convex ring to limit the axial movement of the rotating shaft. By limiting the axial movement of the rotating shaft through the convex ring, it is possible to effectively prevent the rotating shaft and the vertical rotating cylinder from shifting vertically, which would cause the vertical position of the raceway beam to deviate. The vertical rotating cylinder and the rotating shaft are provided with positioning pin holes that correspond horizontally to the upper raceway beam when it is in the transverse direction. The transverse raceway beam can be locked through the positioning pin holes.

[0012] Preferably, the side column main frame includes an outer upright plate and a lifting platform mounting frame. The lifting platform is a screw jack, with its telescopic end vertically extending upwards through the top plate of the lifting platform mounting frame before installing a transverse roller beam support platform. The screw jack is equipped with a manual handle, thereby positioning the transverse roller beam support platform above the lifting platform mounting frame. The structural design is reasonable, and the manual handle allows for emergency operation in case of power failure or motor damage, ensuring the locking of the roller beam. A roller beam buffer pad is installed between the outer upright plate and the transverse upper roller beam to prevent the roller beam from colliding with the side column when moving laterally, thus avoiding damage to components and affecting service life.

[0013] A further preferred embodiment is that a guide cylinder is welded to the center of the bottom side of the longitudinal roller beam support plate, and a roller beam buffer pad is installed on the front side. The lifting column is driven by a motor, and the top of the lifting rod is placed inside the guide cylinder. The guide cylinder radially limits the lifting column, so that it can only move axially.

[0014] More preferably, both the upper and lower roller beams include flange rollers, roller supports, spacers, and spacer mounting seats arranged side-by-side on the crossbeam, ensuring the maximum number of rails transported per layer; the crossbeam of the lower roller beam is directly and laterally fixed on the adjustable bearing beam, and both ends are provided with insert plates for inserting into the corresponding side limit ports of the drive column and side column, so that the overall position and height of the bottom roller beam can be adjusted.

[0015] More preferably, the base has an overall "L" shaped structure, with a limiting strip hole at the vertical end and welded to the floor at the horizontal end, which fully ensures the stable installation of the base structure. The longitudinal support plate is installed on the base by bolts passing through the limiting strip hole, which is convenient to adjust and simple to operate.

[0016] A further preferred embodiment is that the load-bearing beam is made of I-beams, and the corresponding threaded holes on the front and rear of the fixing plate are equipped with positioning rings to ensure the stability of the screw passing through the threaded holes.

[0017] The beneficial effects of this invention are:

[0018] (1) Compared with manually opening, closing and locking the roller beam, the fully automatic control of the roller beam opening and closing is obviously more efficient in transporting steel rails, and the operation is simple, saving time and effort.

[0019] (2) Several position sensors are installed on the side column main frame and the roller beam rotation support mechanism to transmit the position information of the roller beam. Through the sensor layout, the movement direction of the roller beam is accurately grasped, thereby transmitting the signal to the control host. The control host automatically issues the next instruction to complete the fully automatic opening and closing operation of the roller beam. It is highly intelligent, reduces the need for staff to perform on-site operations, and effectively improves the personal safety of staff.

[0020] (3) The lower roller beam is located between the drive column and the side column and is installed on the adjustable height bearing beam. The screw passes through the threaded hole on the fixed plate and is connected to the outside of the wedge. By rotating the screw, the wedge can be moved horizontally to adjust the overall height of the bearing beam and the lower roller beam. The operation is simple and the adjustment accuracy is high. The slight height difference can be manually adjusted. By moving the wedges on both sides of the adjustable height bearing beam inward, the overall height of the lower roller beam is increased. The design is reasonable.

[0021] (4) The longitudinal support plate installed on the base and capable of vertical movement plays a role in strengthening the support of the load-bearing beam, enhancing the stability of the overall structure, ensuring the load-bearing capacity of the load-bearing beam, and can also make corresponding height adjustments according to the height changes of the load-bearing beam, resulting in high overall structural stability.

[0022] In summary, it has the advantages of fully automated opening and closing of the roller beam, simple operation, saving time and labor, high personal safety factor, and high overall structural stability. Attached Figure Description

[0035] The present invention will be further described below with reference to the embodiments and accompanying drawings:

[0036] Combination Figure 1 — Figure 12 As shown, a double-layer fully automatic opening and closing roller beam device for subway rail transportation consists of an upper roller beam 3, a lower roller beam 7, a drive column 1, side columns 2 corresponding to the drive column 1, an automatic control mechanism, and a roller beam rotation support mechanism 4 located on the same longitudinal line as the drive column 1.

[0037] The horizontal upper roller beam 3 is rotatably mounted on the drive column 1 at one end and rests on the side column 2 at the other end. The automatic control mechanism consists of a control host and several position sensors 5 mounted on the side column 2 and the roller beam rotation support mechanism 4 to transmit the position information of the upper roller beam 3.

[0038] The position sensor 5 feeds back a signal to the control host, which then automatically controls the opening and closing of the upper roller beam 3.

[0039] The lower roller beam 7 is located between the drive column 1 and the side column 2, and is installed on the adjustable height load-bearing beam 6.

[0040] The upper raceway beam 3 is composed of wheel flange rollers 36, roller supports 33, spacers 34 and spacers mounting seats 35 arranged side by side on the crossbeam 31, and a crossbeam 31 with a vertical rotating cylinder 32 welded to one end and a horizontal through hole 311 at the other end.

[0041] The side column 2 consists of the side column main frame 21 and the transverse roller beam support platform 22.

[0042] The transverse roller beam support platform 22 is installed at the telescopic top of the elevator 23, and the center of the top of the transverse roller beam support platform 22 is provided with a roller beam positioning column 221 that can pass through the horizontal through hole 311 to fix the transverse roller beam 3.

[0043] The roller beam rotation support mechanism 4 consists of a support main frame 41, a longitudinal roller beam support plate 42, and a lifting column 43 located at the center of the longitudinal roller beam support plate 42.

[0044] When the transverse upper roller beam 3 rotates around the vertical rotating cylinder 32 and rests on the longitudinal roller beam support plate 42, the position sensor 5 feeds back a signal to the control host, and the lifting column 43 automatically rises and passes through the horizontal through hole 311 to fix the longitudinal upper roller beam 3.

[0045] The drive column 1 can be mainly composed of hydraulic cylinders.

[0046] The piston rod of the hydraulic cylinder is connected to the vertical rotating drum 32. The vertical rotating drum 32 can rotate by the piston rod, thereby driving the roller beam 3 to rotate.

[0047] The drive column 1 can also consist of a rotating shaft 11 placed inside the vertical rotating cylinder 32, a column main frame 12 connecting the two ends of the rotating shaft 11, and a drive gear 13 mounted on the drive motor.

[0048] The bottom end of the vertical rotating drum 32 is provided with a driven gear 321 that meshes with the driving gear 13. A bearing 111 is provided between the rotating shaft 11 and the vertical rotating drum 32. The vertical rotating drum 32 can rotate by gear transmission, thereby driving the raceway beam 3 to rotate.

[0049] The lower part of the rotating shaft 11 is provided with a convex ring, and the upper and lower ends of the vertical rotating cylinder 32 are provided with caps. The cap at the lower end abuts against the convex ring to limit the axial movement of the rotating shaft 11.

[0050] The vertical rotating cylinder 32 and the rotating shaft 11 are provided with positioning pin holes that can be horizontally corresponding to the roller beam 3 when it is in the transverse direction.

[0051] The side column main frame 21 consists of an outer vertical plate 211 and a lifting platform mounting frame 212.

[0052] The lifting platform 23 is a screw jack. The telescopic end passes vertically upward through the top plate of the lifting platform mounting frame 212 and is then installed on the transverse roller beam support platform 22. The screw jack is equipped with a manual handle 231.

[0053] A raceway beam buffer pad 213 is installed between the outer vertical plate 211 and the transverse raceway beam 3.

[0054] A guide cylinder 431 is welded to the center of the bottom side of the longitudinal raceway beam support plate 42, and a raceway beam buffer pad 213 is installed on the front side.

[0055] The lifting column 43 is driven by a motor and the top of the lifting rod is placed inside the guide cylinder 431.

[0056] First, the upper roller beam 3 is opened. When the transverse roller beam 3 rotates around the vertical rotating cylinder 32 and rests on the longitudinal roller beam support plate 42, the position sensor 5 sends a feedback signal to the control host, and the lifting column 43 automatically rises and passes through the horizontal through hole 311 to fix the longitudinal roller beam 3.

[0057] After the upper roller beam 3 is opened, the rails on the lower roller beam 7 are unloaded.

[0058] Close the upper roller beam 3, lower the lifting column 43 of the longitudinal roller beam support plate 42 out of the horizontal through hole 311, and then start the drive column 1 to make the roller beam 3 rotate around the vertical rotating cylinder 32 to above the transverse roller beam support platform 2.

[0059] Then, the position sensor 5 on the side column main frame 21 feeds back a signal to the control host, and the transverse roller beam support platform 2 automatically rises. The transverse roller beam 3 is then locked by the roller beam positioning column 221 passing through the horizontal through hole 311 to achieve closure.

[0060] The crossbeam 31 of the lower roller beam 7 is directly and horizontally fixed on the adjustable height bearing beam 6, and both ends are provided with insert plates for inserting into the limiting ports on the corresponding sides of the drive column 1 and the side column 2.

[0061] The adjustable height load-bearing beam 6 consists of a load-bearing beam 61, crossbeam support feet 62 located on the front and rear sides of the bottom of the load-bearing beam 61, and a crossbeam height adjustment mechanism 63.

[0062] The crossbeam support leg 62 consists of a base 621 and a longitudinal support plate 622 mounted on the base 621 and capable of vertical movement.

[0063] The beam height adjustment mechanism 63 consists of a wedge 631, a fixed plate 632 with a threaded hole, and a screw 633 that passes through the threaded hole and connects to the outside of the wedge 631.

[0064] Rotating the screw 633 can drive the wedge 631 to move horizontally, thereby adjusting the overall height of the bearing beam 61 and the lower roller beam 7.

[0065] The base 621 has an overall "L" shaped structure, with a limit strip hole at the vertical end and the horizontal end welded to the floor.

[0066] The longitudinal support plate 622 is installed on the base 621 by bolts passing through the limit strip holes and adjusting its height.

[0067] The load-bearing beam 61 is made of I-beams, and the fixing plate 632 is equipped with positioning rings 634 at the front and rear corresponding threaded holes.

[0068] By rotating the screws 633 on the front and rear sides of the bottom of the load-bearing beam 61 together, the wedges are brought closer together, and the load-bearing beam 61 is lifted by the inclined plane.

[0069] Then adjust the height of the longitudinal support plate 622 so that it abuts against the load-bearing beam 61.
