Description

Technical Field

[0001] This invention relates to the field of rail transportation technology, and in particular to a double-sided operating spacer device. Background Technology

[0002] Long rail transport trains are specialized trains composed of various special vehicles with different functions and structures, used for transporting long rails. In the construction of seamless railway lines, these trains are responsible for loading, transporting, unloading, and recycling long rails. When using long rail trainsets to transport rails, spacer devices are specialized equipment to prevent lateral shifting of the rails during transport. The spacer devices are installed on the rail transport vehicle, which has three sets of roller beams: one in the middle and one at each end. Each set of roller beams is fixed to pillars on both sides of the vehicle, consisting of four layers and four beams. The roller beams can rotate 90° around one side of the pillar to meet the requirements of rail loading operations. The spacer devices are installed on the middle set of roller beams. These spacer devices must be laid flat during loading and unloading and erected during rail transport to prevent lateral shifting of the rails.

[0003] An existing spacer device consists of a spacer, a spacer shaft, and a spacer control lever. The spacer is welded and fixed to the spacer shaft. The spacer control lever is fixed to the column by a mounting plate and connected to the spacer shaft by a connecting shaft. The spacer control lever can drive the spacer shaft to rotate 90°, realizing the flattening and erection of the spacer. When erected, the spacer control lever can be locked to prevent the spacer from being laid flat freely.

[0004] However, in the existing technology, the spacer control lever is installed on a pillar on one side of the vehicle body, and the spacer device can only be operated from this side. When working on the line, if there is a adjacent line on this side, a vehicle may pass by at any time, which poses a major safety hazard to operating the spacer device. Summary of the Invention

[0005] The purpose of this invention is to at least solve one of the technical problems existing in the prior art by providing a double-sided operating spacer device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: comprising: a first side column, a second side column spaced apart on one side of the first side column, both the first and second side columns being welded and fixed on a rail transport vehicle, a raceway assembly being provided between the first and second side columns, the raceway assembly including a raceway steel beam assembly, a double-sided operating spacer assembly, a drive shaft assembly and a mounting plate, the drive shaft assembly being bolted to the raceway steel beam assembly via the mounting plate, the raceway steel beam assembly being disposed between the first and second side columns and close to the top surfaces of the first and second side columns, and both the double-sided operating spacer assembly and the drive shaft assembly being disposed between the first and second side columns and close to the bottom surfaces of the first and second side columns.

[0007] The above technical solution, by setting up a drive shaft assembly and cooperating with the double-sided operating spacer assembly, can lock the spacer. Both the drive shaft assembly and the double-sided operating spacer assembly can be operated from both sides, avoiding the safety hazards of operating near the line at the work site and improving the safety of the workers.

[0008] Preferably, the transmission shaft assembly includes two locking seats, a first rotating shaft, a lead screw, a retaining sleeve, a second rotating shaft, and two retaining rings. The first rotating shaft and the second rotating shaft are respectively welded and fixed to both ends of the lead screw. The two locking seats are respectively welded and fixed to the ends of the first rotating shaft and the second rotating shaft that are far apart from each other. The retaining sleeve is threadedly connected to the lead screw. Two first through holes are opened on one side of the first side post, and two second through holes are opened on one side of the second side post. A rocker arm is provided inside each of the first through holes and the second through holes. The two retaining rings are respectively fixedly sleeved on the outer circular wall surfaces of the first rotating shaft and the second rotating shaft.

[0009] Through the above technical solution, by setting a locking seat and inserting a rocker arm into the locking seat, the rocker arm is combined with the first locking seat, which drives the lead screw to rotate, allowing the retaining sleeve to move laterally. The two retaining rings can respectively limit the first rotating shaft and the second rotating shaft, preventing the first rotating shaft and the second rotating shaft from moving to the other side as a whole when the operator rotates the lead screw near the first rotating shaft or the second rotating shaft.

[0010] Preferably, the double-sided operating spacer assembly includes a spacer shaft, a stop block, a spacer body, a base plate, a shaft stop, a stop block, and two connecting shafts. The stop block is welded to the base plate, the shaft stop is welded and fixed to the spacer shaft, the base plate is welded and fixed to the spacer shaft, and the two connecting shafts are respectively welded and fixed to both ends of the spacer shaft.

[0011] Through the above technical solution, by setting a stop block, the shaft can be clamped between the stop block and the stop sleeve, thereby locking the spacer iron shaft. When the stop sleeve is removed, the rocker arm engages with the connecting shaft, driving the spacer iron shaft to rotate, so that the spacer iron body can rotate 90 degrees, completing the flattening and erecting actions.

[0012] Preferably, the raceway steel beam assembly includes a rotating sleeve and a raceway steel beam body. The rotating sleeve is fixedly installed on one side of the raceway steel beam body, and one side of the rotating sleeve is fixedly installed on one side of the first side column. The top surface of the mounting plate is welded and fixed to the bottom surface of the raceway steel beam body.

[0013] The above technical solution allows the roller rail steel beam to rotate 90 degrees on one side of the first side column by setting a rotating sleeve, which is used to facilitate the unloading operation.

[0014] Preferably, the end of the rocker arm is cross-shaped, and both locking seats and both connecting shafts are provided with cross grooves that cooperate with the rocker arm.

[0015] By using the above technical solution, and by setting a rocker arm, with the end of the rocker arm being cross-shaped and engaging with the locking seat and the connecting shaft, the rotating spacer iron shaft and lead screw can be driven more stably.

[0016] Preferably, the raceway steel beam assembly further includes two first support plates, both of which are welded and fixed to the bottom surface of the raceway steel beam body.

[0017] The above technical solution provides support for the main body of the raceway steel beam by setting up a first support plate.

[0018] Preferably, the double-sided operating spacer assembly further includes two second support plates, both of which are welded and fixed to the base plate.

[0019] The above technical solution involves setting a second support plate, which is used to install the spacer shaft on the bottom surface of the raceway steel beam body. This ensures that when the spacer body rotates 90 degrees, it can precisely isolate the gap between the raceway steel beam body and the railcar, preventing the rail from shifting laterally.

[0020] Preferably, a collar is movably fitted on the outer circular wall surface of both rockers, and a limit ring is welded and fixed on the outer circular wall surface of the rocker, with one end of the collar fitting against one end of the limit ring.

[0021] The above technical solution, by setting a collar, makes it more convenient for workers to use the joystick, and the limiting ring can prevent the collar from falling off the joystick when workers turn the joystick.

[0022] Compared with the prior art, the beneficial effects of the present invention are:

[0023] (1) The double-sided operating spacer device can lock the spacer by cooperating with the transmission shaft assembly and the double-sided operating spacer assembly. Both the transmission shaft assembly and the double-sided operating spacer assembly are provided with operating ports at both ends. Both operating ports can operate the transmission shaft assembly and the double-sided operating spacer assembly to unlock and lock the spacer. When the rail loading operation requires operation on one side of the operating port to be close to the line, the other operating port can be used to avoid the safety hazards of operation close to the line at the work site, improve the safety of the workers, and reduce the accident rate.

[0024] (2) The double-sided operating spacer device can support the main body of the roller rail steel beam through the first support plate, and install the spacer shaft on the bottom surface of the main body of the roller rail steel beam through the second support plate, so that when the spacer body rotates 90 degrees, it can just isolate the gap between the main body of the roller rail steel beam and the railcar, and prevent the rail from shifting laterally. By setting the first support plate, the main body of the roller rail steel beam can be supported.

[0025] (3) The double-sided operating spacer device can lock the spacer shaft by clamping the shaft between the stop and the sleeve. When the sleeve is removed, the spacer shaft is driven to rotate by the rocker arm and the connecting shaft, so that the spacer body can rotate 90 degrees to complete the flattening and erecting actions. By setting the rocker arm, the rocker arm end is cross-shaped and is connected to the locking seat and the connecting shaft, which can drive the rotating spacer shaft and the lead screw more stably.

[0026] (4) The double-sided operating spacer device can rotate the main body of the raceway steel beam to ninety degrees on one side of the first side column by rotating the sleeve to cooperate with the rail unloading operation. By inserting a rocker into the locking seat, the rocker is engaged with the first locking seat, which drives the screw to rotate, so that the sleeve can move laterally. The two retaining rings can respectively limit the first rotating shaft and the second rotating shaft, preventing the first rotating shaft and the second rotating shaft from moving to the other side as a whole when the operator rotates the screw near the first rotating shaft or the second rotating shaft.

[0027] (5) The double-sided operating spacer device is equipped with a collar, which makes it more convenient for the operator to use the rocker arm. The limiting ring can prevent the collar from falling off the rocker arm when the operator turns the rocker arm. Attached Figure Description

[0037] This section will describe in detail specific embodiments of the present invention. Preferred embodiments of the present invention are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and overall technical solution of the present invention, but they should not be construed as limiting the scope of protection of the present invention.

[0038] Please see Figure 1-7This invention provides a technical solution: a double-sided operating spacer device, including a first side column 1, with a second side column 4 spaced apart on one side of the first side column 1. A locking mechanism for locking the raceway steel beam body 112 is welded and fixed on one side of the second side column 4. Both the first side column 1 and the second side column 4 are welded and fixed on the rail transport vehicle. A raceway assembly 3 is provided between the first side column 1 and the second side column 4. The raceway assembly 3 includes a raceway steel beam assembly 11, a double-sided operating spacer assembly 12, a drive shaft assembly 13, and a mounting plate 14. The drive shaft assembly 13 is bolted to the raceway steel beam assembly 11 via the mounting plate 14. The raceway steel beam assembly 11 is located on the first side column 1. Between one side post 1 and the second side post 4, and near the top surface of the first side post 1 and the second side post 4, the double-sided operating spacer assembly 12 and the drive shaft assembly 13 are both located between the first side post 1 and the second side post 4 and near the bottom surface of the first side post 1 and the second side post 4. By setting the drive shaft assembly 13 and cooperating with the double-sided operating spacer assembly 12, the spacer can be locked. Both the drive shaft assembly 13 and the double-sided operating spacer assembly 12 can be operated from both sides, avoiding the safety hazards of operating near the line at the work site and improving the safety of the workers. The drive shaft assembly 13 includes two locking seats 131 and a first rotating... The structure includes a moving shaft 132, a lead screw 133, a retaining sleeve 134, a second rotating shaft 135, and two retaining rings 136. The lead screw 133 is an existing structure and will not be described in detail here. The first rotating shaft 132 and the second rotating shaft 135 are welded and fixed to both ends of the lead screw 133. Two locking seats 131 are welded and fixed to the far ends of the first rotating shaft 132 and the second rotating shaft 135. The retaining sleeve 134 is threaded to the lead screw 133. Two first through holes 5 are opened on one side of the first side post 1, and two second through holes 6 are opened on one side of the second side post 4. A rocker arm 2 is installed inside both the first through holes 5 and the second through holes 6. The rocker arm 2 has a Z-shaped structure and is... Made of metal, two retaining rings 136 are respectively fixedly sleeved on the outer circular walls of the first rotating shaft 132 and the second rotating shaft 135. By setting a locking seat 131 and inserting a rocker arm 2 into the locking seat 131, the rocker arm 2 is engaged with the first locking seat 131, driving the lead screw 133 to rotate, so that the retaining sleeve 134 can move laterally. The two retaining rings 136 can respectively limit the first rotating shaft 132 and the second rotating shaft 135, preventing the first rotating shaft 132 and the second rotating shaft 135 from moving to the other side as a whole when the operator rotates the lead screw 133 near the side of the first rotating shaft 132 or the second rotating shaft 135.

[0039] Please see Figure 1-7The double-sided operating spacer assembly 12 includes a spacer shaft 122, a stop block 126, a spacer body 123, a base plate 124, a shaft stop 125, the stop block 126, and two connecting shafts 127. The spacer shaft 122 is an existing structure and will not be described in detail here. The stop block 126 is welded to the base plate 124. The shaft stop 125 is welded and fixed to the spacer shaft 122. The base plate 124 is welded and fixed to the spacer shaft 122. The two connecting shafts 127 are respectively welded and fixed to both ends of the spacer shaft 122. By setting the stop block 126, the shaft stop 125 can be clamped between the two through the cooperation of the stop block 126 and the stop sleeve 134. This locks the spacer shaft 122. When the retaining sleeve 134 is removed, the rocker arm 2 engages with the connecting shaft 127, causing the spacer shaft 122 to rotate, allowing the spacer body 123 to rotate 90 degrees, completing the flattening and erecting actions. Both rocker arms 2 have movably fitted collars 21 on their outer circular walls. Limiting rings 22 are welded and fixed to the outer circular walls of the rocker arms 2, with one end of the collar 21 fitting against one end of the limiting ring 22. The collars 21 make it easier for operators to use the rocker arms 2, while the limiting rings 22 prevent the collars 21 from falling off the rocker arms 2 when the operators rotate them.

[0040] The axle stop 125 can be clamped between the stop block 126 and the stop sleeve 134, thereby locking the spacer iron rotating shaft 122. When the stop sleeve 134 is removed, the rocker arm 2 is connected to the connecting shaft 127, which drives the spacer iron rotating shaft 122 to rotate, so that the spacer iron body 123 can rotate 90 degrees to complete the flattening and erecting actions. By setting the rotating sleeve 111, the roller rail steel beam body 112 can be rotated 90 degrees on one side of the first side column 1 to cooperate with the rail unloading operation. By setting the rocker arm 2, the end of the rocker arm 2 is cross-shaped and connected to the locking seat 131 and the connecting shaft 127, which can drive the rotating spacer iron rotating shaft 122 and the lead screw 133 more stably.

[0041] Please see Figure 1-7The roller rail steel beam component 11 includes a rotating sleeve 111 and a roller rail steel beam body 112. The roller rail steel beam body 112 is an existing structure and will not be described in detail here. The rotating sleeve 111 is fixedly installed on one side of the roller rail steel beam body 112. One side of the rotating sleeve 111 is fixedly installed on one side of the first side column 1. The top surface of the mounting plate 14 is welded and fixed to the bottom surface of the roller rail steel beam body 112. By setting the rotating sleeve 111, the roller rail steel beam body 112 can be rotated 90 degrees on one side of the first side column 1 to cooperate with the rail unloading operation. The end of the rocker arm 2 is cross-shaped. The two locking seats 131 and the two connecting shafts 127 are all provided with cross grooves that cooperate with the rocker arm 2. By setting the rocker arm 2, and by the cross-shaped end of the rocker arm 2 cooperating with the locking seats 131 and the connecting shafts 127, the rotating spacer iron shaft 122 and the lead screw 133 can be driven more stably.

[0042] Please see Figure 1-7 The roller rail steel beam assembly 11 also includes two first support plates 113, both of which are welded and fixed to the bottom surface of the roller rail steel beam body 112. By setting the first support plates 113, the roller rail steel beam body 112 can be supported. The double-sided operating spacer assembly 12 also includes two second support plates 121, both of which are welded and fixed to the base plate 124. By setting the second support plates 121, the spacer shaft 122 is installed on the bottom surface of the roller rail steel beam body 112, so that when the spacer body 123 rotates 90 degrees, it can just isolate the gap between the roller rail steel beam body 112 and the railcar, preventing the rail from shifting laterally.

[0043] Working principle: Before rail installation, hold the collar 21 and select either the first side post 1 or the second side post 4 according to the actual situation of the work site. After selection, pass one end of the cross end of the rocker arm 2 through the inside of the first through hole 5 or the second through hole 6 and engage it with the cross groove of the locking seat 131. Then rotate the rocker arm 2 to rotate the first rotating shaft 132, the second rotating shaft 135 and the lead screw 133. At this time, under the action of the threaded connection between the retaining sleeve 134 and the lead screw 133, the retaining sleeve 134 moves laterally until the retaining sleeve 134 separates from the stop block 126 and the two are misaligned. At this time, the shaft stop 125 can rotate normally. Then, pull the rocker arm 2 out of the inside of the first through hole 5 or the second through hole 6 and pass one end of the cross end of the rocker arm 2 into the inside of another first through hole 5 or the second through hole 6 and engage it with the cross groove of the engaging shaft 127. When the slots are engaged, rotate the rocker arm 2 to rotate the engaging shaft 127 and the spacer iron shaft 122, causing the spacer iron shaft 122 to drive the spacer iron body 123 to rotate. Rotate the spacer iron shaft 122 ninety degrees to flatten the spacer iron body 123. At this point, release the locking device of the roller rail beam body 112 and rotate the roller rail beam body 112 ninety degrees around the first side column 1. Then, the rail loading operation can be carried out. After the rail loading operation is completed, rotate the spacer iron shaft 122 ninety degrees in the opposite direction to make the spacer iron body 123 stand up again. Then, pull out the rocker arm 2, engage it with the locking seat 131, and rotate it to move the retaining sleeve 134 laterally to reset it. At this point, the cooperation between the retaining block 126 and the retaining sleeve 134 clamps the axle retainer 125 between them, thereby restricting the rotation of the axle retainer 125 and completing the locking.

[0044] By setting up a transmission shaft assembly 13, which cooperates with the double-sided operating spacer assembly 12, the spacer can be locked. Both the transmission shaft assembly 13 and the double-sided operating spacer assembly 12 can be operated from both sides, avoiding safety hazards of operating near the line at the work site and improving the safety of the workers. By setting up a locking seat 131, and inserting a rocker arm 2 into the locking seat 131, the rocker arm 2 is engaged with the first locking seat 131, driving the lead screw 133 to rotate, allowing the retaining sleeve 134 to move laterally. The two retaining rings 136 can respectively limit the first rotating shaft 132 and the second rotating shaft 135, preventing the first rotating shaft 132 and the second rotating shaft 135 from moving to the other side when the worker rotates the lead screw 133 near the first rotating shaft 132 or the second rotating shaft 135.

[0045] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
