Description

Technical Field

[0001] The invention belongs to the field of railway construction equipment, and in particular relates to a device for equidistantly laying railway sleepers. Background Art

[0002] As we all know, railways are usually paved with gravel to ensure that the ground will not be crushed by the weight of the train when it is running. At the same time, a layer of sleepers needs to be laid evenly before building the railway. The rails need to be fixed on the sleepers, and the sleepers need to be evenly distributed.

[0003] This equipment can perform intelligent data monitoring to ensure that the sleepers are placed at equal spacing.

[0004] During the process of laying sleepers, the gravel can be automatically cleaned to create a ground pit that can accommodate the sleepers, and the sleepers are placed in it to prevent the sleepers from being laid directly on uneven gravel and causing tilting.

[0005] After the sleepers are laid, the gravel is automatically moved to cover the edges of the sleepers, and at the same time, the sleepers are beaten with a rubber hammer to place them more stably. Summary of the invention

[0010] Furthermore, the stabilizing device includes two racks fixed on the lower side walls of the fixing rod, a force transmission rail is fixed inside the laying slide rod, a gear is rotatably provided on the force transmission rail, a stabilizing slider is slidably provided on the laying slide rod, the rack is fixed on the side wall of the near-axial end of the stabilizing slider, the rack and the gear can mesh and transmit, and a limit block is fixed on the stabilizing slider.

[0011] Furthermore, the cleaning device includes a rotating cavity fixed at the lower end of the laying slide bar, the main rotating shaft extends into the rotating cavity, a rotating connecting block is fixed on the main rotating shaft, the main rotating shaft can drive the rotating cavity to rotate, a buffer block is fixed at the other end of the rotating cavity, a cleaning plate is rotatably provided on the buffer block, a secondary rotating shaft is fixed on the end face of the main rotating shaft, the secondary rotating shaft passes through the rotating cavity and extends into the interior of the cleaning plate, a bearing is provided between the buffer block and the secondary rotating shaft, an axle frame is fixed inside the cleaning plate, a cleaning plate rotating shaft is fixed on the axle frame, a reduction box is connected between the cleaning plate rotating shaft and the buffer block, and a shock absorbing device is provided on the cleaning plate, and the shock absorbing device is used to reduce the impact of the sleepers falling on the cleaning device.

[0012] Furthermore, the shock absorbing device comprises a shock absorbing block fixed on the cleaning plate, a soft block is slidably arranged inside the shock absorbing block, and a shock absorbing spring is connected between the soft block and the shock absorbing block.

[0013] Furthermore, the hammering device includes an arc-shaped gear ring fixed inside the rotating cavity, a hammering block is rotatably provided inside the rotating cavity, a rubber hammer is fixed on the hammering block, a tooth pattern is provided at the lower end of the hammering block, the lower end of the hammering block can engage with the rotating cavity, an inner toothed rotating hole is provided at the lower part of the hammering block, an outer toothed sleeve is rotatably provided inside the inner toothed rotating hole, a rotating connecting block is connected between the outer toothed sleeve and the main rotating shaft, and the outer toothed sleeve can drive the hammering block and the main rotating shaft to rotate in opposite directions by engaging with the inner toothed rotating hole.

[0014] When using this equipment, the sleepers to be laid are stored in the supply cavity. When the wheel has traveled a certain distance, the distance detector transmits an electrical signal to control the sliding of the telescopic slide bar on one side. The telescopic slide bar slides to open the channel. At the same time, the telescopic slide bar slides, and the block slides on the slide slot. When the block slides on the guide block due to the force of the spring and enters the slot, the rotating disk starts to rotate, and a sleeper falls from the supply cavity to the laying cavity. The laying device in the laying cavity starts to lay the railway sleepers. By detecting the predetermined distance traveled by the wheel, the sleepers are automatically released by the electrical signal output control, so as to achieve the effect of automatically planning the placement of sleepers at equal distances, avoiding the need for equal distance measurement for manual placement.

[0015] When the sleeper falls into the laying cavity, it will fall on the cleaning board. The spring between the fixed rod and the laying slide rod will play a certain buffering role. The soft block on the cleaning board sliding in the shock-absorbing block will also produce a certain buffering effect, avoiding damage to the rotating shaft inside the cleaning board due to the sleeper falling on the cleaning board, which can extend the service life of the equipment.

[0016] After the sleeper falls on the cleaning board, due to the influence of gravity, the cleaning board is driven to slide down, and the laying slide bar is driven to slide downward at the same time. When the laying slide bar slides downward, the intelligent coupling at the bottom of the laying slide bar will be connected with the output shaft, and the rotational force on the motor will be transmitted to the main rotating shaft. The main rotating shaft drives the rotating cavity as a whole to rotate through the rotating connecting block. At the same time, the secondary rotating shaft will also rotate with the main rotating shaft, and the secondary rotating shaft will drive the cleaning board shaft through the reduction gear box. However, after the deceleration effect of the reduction gear box, the rotation speed of the cleaning board shaft will be less than the rotation speed of the secondary rotating shaft, that is, the overall rotation speed of the cleaning board is less than the overall rotation speed of the rotating cavity. The cleaning board will rotate, and before placing the sleeper, one end of the cleaning board will scrape the ground to clean it, push the stones aside, and clean out a pit. As the inclination angle of the cleaning board gradually increases, the sleeper will be placed in the pit that has just been cleaned. When the rotating chamber rotates as a whole, the hammering rotating block inside the rotating chamber will start to rotate due to the meshing transmission between the outer toothed sleeve and the inner toothed rotating hole, and the hammering rotating block and the cleaning plate rotate in different directions.

[0017] In addition, when the laying slide bar slides downward, the rack on the fixed rod can mesh with the gear on the force transmission rail, and the gear can mesh with the rack on the stabilizing slider. At this time, the stabilizing slider will slide downward through the transmission force, and the limit block on the stabilizing slider will slide downward to restrict the direction of the sleeper, preventing the sleeper from flipping over when sliding off the cleaning board, causing the sleeper placement direction to be different from the established assembly direction.

[0018] When the sleeper falls into the pit, the motor rotates in the reverse direction, driving the rotating chamber to rotate in the reverse direction as a whole, and the cleaning plate rotates in the reverse direction as a whole, but the cleaning plate rotates slower than the rotating chamber, that is, the cleaning plate rotates slower than the hammering block, and the hammering block and the cleaning plate rotate in different directions. The reverse rotation of the cleaning plate will push the stones previously cleaned to one side toward the sleeper, and the hammering block will hammer downward, and the hammering will be performed before the edge of the sleeper is covered by the stones, which can make the sleeper more stably placed on the stone surface, facilitating subsequent construction.

[0019] Finally, as the motor rotates for a predetermined time, it is disconnected from the intelligent coupling, the laying slide bar slides upward, the stabilizing slider is reset, the cleaning plate is reset, and the hammering block is reset. After the distance detector detects that the predetermined distance has been completed, the sleeper placement work continues. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] like Figure 2 , Figure 3 and Figure 5As shown, the cleaning device includes a rotating chamber 36 fixed at the lower end of the laying slide bar 24, the main rotating shaft 33 extends into the rotating chamber 36, and a rotating connecting block 37 is fixed on the main rotating shaft 33. The main rotating shaft 33 can drive the rotating chamber 36 to rotate, and a buffer block 41 is fixed at the other end of the rotating chamber 36. A cleaning plate 45 is rotatably provided on the buffer block 41. A secondary rotating shaft 39 is fixed on the end surface of the main rotating shaft 33. The secondary rotating shaft 39 passes through the rotating chamber 36 and extends into the cleaning plate 45. A bearing 42 is provided between the buffer block 41 and the secondary rotating shaft 39. An axle frame 44 is fixed inside the cleaning plate 45, and a cleaning plate rotating shaft 49 is fixed on the axle frame 44. A reduction box 43 is connected between the cleaning plate rotating shaft 49 and the buffer block 41. A shock absorbing device is provided on the cleaning plate 45. The shock absorbing device is used to reduce the impact of the sleepers falling on the cleaning device.

[0033] like Figure 2 , Figure 3 and Figure 5 As shown, the shock absorbing device includes a shock absorbing block 46 fixed on a cleaning plate 45 , a soft block 47 is slidably arranged inside the shock absorbing block 46 , and a shock absorbing spring 48 is connected between the soft block 47 and the shock absorbing block 46 .

[0034] like Figure 2 , Figure 3 and Figure 5 As shown, the hammering device includes an arcuate gear ring 40 fixed inside a rotating cavity 36, a hammering rotating block 34 is rotatably provided in the rotating cavity 36, a rubber hammer 35 is fixed on the hammering rotating block 34, a tooth pattern is provided at the lower end of the hammering rotating block 34, and the lower end of the hammering rotating block 34 can engage with the rotating cavity 36, an inner tooth pattern rotating hole 22 is provided at the lower part of the hammering rotating block 34, an outer tooth pattern shaft sleeve 38 is rotatably provided in the inner tooth pattern rotating hole 22, a rotating connecting block 37 is connected between the outer tooth pattern shaft sleeve 38 and the main rotating shaft 33, and the outer tooth pattern shaft sleeve 38 can drive the hammering rotating block 34 and the main rotating shaft 33 to rotate in opposite directions by engaging with the inner tooth pattern rotating hole 22.

[0035] When using this device, the supply chamber 11 stores the sleepers to be laid. When the wheel 12 has traveled a certain distance, the distance detector 13 transmits an electrical signal to control the telescopic slide bar 14 on one side to slide. The telescopic slide bar 14 slides to open the channel. At the same time, the telescopic slide bar 14 slides, and the block 16 slides on the slide slot 17. When the block 16 slides on the guide block 19 due to the force given by the spring 22 and enters the inside of the card slot 18, the rotating disk 15 starts to rotate, and a sleeper is dropped from the supply chamber 11 into the laying chamber 20. The laying device in the laying chamber 20 is started to lay the railway sleepers. By detecting that the wheel 12 has traveled a predetermined distance, the sleepers are automatically released by the electrical signal output control, so as to achieve the effect of automatically planning the placement of sleepers at equal distances, avoiding the need for equal distance measurement for manual placement.

[0036] When the sleeper falls into the laying cavity 20, the sleeper will fall on the cleaning plate 45. The spring 22 between the fixed rod 21 and the laying slide rod 24 plays a certain buffering role. The soft block 47 on the cleaning plate 45 sliding in the shock-absorbing block 46 will also produce a certain buffering effect, thereby avoiding damage to the rotating shaft inside the cleaning plate 45 due to the sleeper falling on the cleaning plate 45, which can extend the service life of the equipment.

[0037] After the sleeper falls on the cleaning plate 45, due to the influence of gravity, the cleaning plate 45 is driven to slide down, and the laying slide bar 24 is driven to slide downward. When the laying slide bar 24 slides downward, the intelligent coupling 30 at the lower part of the laying slide bar 24 will be connected with the output shaft 32, and the rotational force on the motor 31 will be transmitted to the main rotating shaft 33. The main rotating shaft 33 drives the rotating cavity 36 to rotate as a whole through the rotating connecting block 37. At the same time, the auxiliary rotating shaft 39 will also rotate with the main rotating shaft 33, and the auxiliary rotating shaft 39 will be rotated through the reduction box 43 drives the cleaning plate shaft 49, but after the deceleration effect of the reduction box 43, the rotation speed of the cleaning plate shaft 49 will be less than the rotation speed of the auxiliary rotating shaft 39, that is, the overall rotation speed of the cleaning plate 45 is less than the overall rotation speed of the rotating chamber 36, and the cleaning plate 45 will rotate. Before placing the sleeper, one end of the cleaning plate 45 will scrape the ground to clean it, push the stones aside, and clean out a pit. The sleeper will gradually increase as the tilt angle of the cleaning plate 45, and the sleeper will be placed in the pit just cleaned. When the rotating chamber 36 rotates as a whole, the hammering rotating block 34 inside the rotating chamber 36 will start to rotate because of the meshing transmission between the outer toothed sleeve 38 and the inner toothed rotating hole 22, and the hammering rotating block 34 and the cleaning plate 45 have different rotation directions.

[0038] In addition, when the laying slide bar 24 slides downward, the rack 25 on the fixing rod 21 can mesh with the gear 27 on the force transmission rail 26 for transmission, and the gear 27 can mesh with the rack 25 on the stabilizing slider 28 for transmission. At this time, the stabilizing slider 28 will slide downward through the transmission force, and the limit block 29 on the stabilizing slider 28 will slide downward to restrict the direction of the sleeper, thereby preventing the sleeper from flipping over when sliding off the cleaning plate 45, causing the placement direction of the sleeper to be different from the established assembly direction.

[0039] When the sleeper falls into the pit, the motor 31 rotates in the reverse direction, driving the rotating chamber 36 to rotate in the reverse direction as a whole, and the cleaning plate 45 rotates in the reverse direction as a whole, but the cleaning plate 45 rotates slower than the rotating chamber 36, that is, the cleaning plate 45 rotates slower than the hammering block 34, and the hammering block 34 and the cleaning plate 45 have different rotation directions. The reverse rotation of the cleaning plate 45 will push the stones previously cleaned to one side toward the sleeper, and the hammering block 34 will hammer downward, and the hammering will be performed before the edge of the sleeper is covered by the stones, so that the sleeper can be placed more stably on the stone surface, which is convenient for subsequent construction.

[0040] Finally, as the motor 31 rotates for a predetermined time and then disengages from the intelligent coupling 30, the laying slide bar 24 slides upward, the stabilizing slider 28 is reset, the cleaning plate 45 is reset, and the hammering turn block 34 is reset. After the distance detector 13 detects that the predetermined distance has been completed, the sleeper placement work is continued.

[0041] Compared with the prior art, the railway equidistant sleeper laying device has the following advantages:

[0042] 1. By detecting the predetermined distance traveled by the wheels, the sleepers are automatically released through the output of electrical signals, so as to automatically plan the placement of sleepers at equal distances, thus avoiding the need for equal distance measurements for manual placement.

[0043] 2. The soft block on the cleaning board will slide in the shock-absorbing block and produce a certain buffering effect, thus avoiding damage to the rotating shaft inside the cleaning board caused by the sleepers falling on the cleaning board, and thus extending the service life of the equipment.

[0044] 3. The restriction on the direction of the sleepers prevents the sleepers from turning over when they slide off the cleaning plate 45, causing the placement direction of the sleepers to be different from the established assembly direction.

[0045] 4. Hammering the sleepers before their edges are covered by stones can ensure that they are more stably placed on the stone surface, facilitating subsequent construction.

[0046] The above descriptions are merely embodiments of the present invention, and are not intended to limit the patent protection scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention's specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.

By detecting that the wheel has traveled a predetermined distance, the sleepers are automatically released by means of the electrical signal output control, so as to achieve the effect of automatically planning the placement of sleepers at equal distances, avoiding the need for equal distance measurement for manual placement; When the sleepers fall into the laying cavity, they will fall on the cleaning board. The spring between the fixed rod and the laying slide rod will play a certain buffering role. The soft block on the cleaning board will slide in the shock-absorbing block and will also play a certain buffering role, thus avoiding the damage to the rotating shaft inside the cleaning board caused by the sleepers falling on the cleaning board, which can extend the service life of the equipment. After the sleeper falls on the cleaning board, due to the influence of gravity, the cleaning board is driven to slide down, and the laying slide bar is driven to slide down at the same time. When the laying slide bar slides down, the intelligent coupling at the bottom of the laying slide bar will be connected with the output shaft, and the rotational force on the motor will be transmitted to the main rotating shaft. The main rotating shaft drives the rotating cavity as a whole to rotate through the rotating connecting block. At the same time, the auxiliary rotating shaft will also rotate with the main rotating shaft, and the auxiliary rotating shaft will drive the cleaning board shaft through the reduction gear box. The cleaning board will rotate. Before placing the sleeper, one end of the cleaning board will scrape the ground to clean it, push the stones aside, and clean out a pit. As the tilt angle of the cleaning board gradually increases, the sleeper will be placed in the pit that has just been cleaned. When the rotating chamber rotates as a whole, the hammering rotating block inside the rotating chamber will start to rotate due to the meshing transmission between the outer toothed sleeve and the inner toothed rotating hole, and the hammering rotating block and the cleaning plate rotate in different directions; When the laying slide bar slides downward, the rack on the fixed rod can mesh with the gear on the force transmission rail, and the gear can mesh with the rack on the stable slider for transmission. At this time, the stable slider will slide downward through the transmission force, and the limit block on the stable slider will slide downward to limit the direction of the sleeper; When the sleeper falls into the pit, the motor rotates in the reverse direction, driving the rotating chamber to rotate in the reverse direction as a whole, and the cleaning plate rotates in the reverse direction as a whole, but the cleaning plate rotates slower than the rotating chamber, that is, the cleaning plate rotates slower than the hammering block, and the hammering block and the cleaning plate rotate in different directions. The reverse rotation of the cleaning plate will push the stones that have been cleaned to one side toward the sleeper, and the hammering block will hammer downwards; Finally, as the motor rotates for a predetermined time and then disengages from the intelligent coupling, the laying slide bar slides upward, the stabilizing slider is reset, the cleaning plate is reset, and the hammering block is reset. After the distance detector detects that the predetermined distance has been completed, the sleeper placement work continues.
