Description

Technical Field

[0001] The invention relates to the field of railway construction, and more particularly to a vibrating device for pouring turnout concrete. Background Art

[0002] A turnout is a line connection device that allows locomotives and vehicles to transfer from one track to another. It is also one of the weak links of the track. It is usually laid in large quantities at stations and marshalling yards. During the laying process, in order to improve its bearing capacity and stability, reinforced concrete needs to be laid at the bottom of the turnout.

[0003] During the construction process, sleepers and tracks are first set up, steel cages are tied between the sleepers, and the formwork is set up before pouring. After pouring, the concrete must be vibrated to increase its compactness and ensure its strength. The existing vibrating device is usually a vibrating rod, that is, the vibrating rod is manually inserted into the place to be vibrated. During the vibration process, it cannot touch the track and sleepers to avoid displacement.

[0004] However, in actual operation, due to the large width of the turnout, workers need to stand on the sleepers or tracks to perform vibrating operations, and the vibrating rod will vibrate continuously as a whole during the work process. The vibration will be transmitted to the sleepers or tracks through the human body, which will not only cause great damage to human organs, but also easily cause the sleepers or tracks to loosen and shift, affecting the construction quality and causing serious safety hazards.

[0005] Therefore, a new type of vibrating device is needed to meet the construction requirements of high-standard railway turnouts. Summary of the invention

[0006] An object of the present invention is to provide a new technical solution for a vibrating device during the pouring of turnout concrete.

[0007] According to a first aspect of the present invention, a vibrating device for pouring turnout concrete is provided, comprising a driving device and a vibrating rod, wherein the driving device drives the vibrating rod to vibrate, the driving device is provided with a handle, the driving device is provided with a vibration isolation mechanism and a vibration motor, the vibrating rod is installed in the driving device via the vibration isolation mechanism, and the vibration motor is installed on the vibrating rod.

[0008] Through this solution, during the process of vibration motor driving the vibrating rod to vibrate, the presence of the vibration isolation mechanism will greatly weaken the vibration amplitude transmitted to the driving device, thereby reducing damage to human organs and avoiding the transmission of vibration to the sleepers and rails through the human body, thereby ensuring the accuracy of the position of the sleepers and rails and improving the safety of construction.

[0009] Preferably, the vibration isolation mechanism includes a vertical vibration isolation spring and a horizontal vibration isolation ring. A mounting plate is provided on the top of the vibrating rod, the vibration motor is installed on the top of the mounting plate, the vertical vibration isolation spring is supported to the bottom of the mounting plate, the horizontal vibration isolation ring is fixed to the through hole at the bottom of the driving device, and the vibrating rod passes through the horizontal vibration isolation ring and extends out of the driving device.

[0010] Through this solution, the vertical vibration isolation spring and the horizontal vibration isolation ring can isolate the driving device and the vibrating rod to avoid direct rigid contact between the two, thereby filtering the vibration in the vertical and horizontal directions and reducing the transmission of vibration.

[0011] Preferably, the horizontal vibration isolation ring includes a fixed sleeve, a linear bearing and a horizontal vibration isolation spring, the fixed sleeve is coaxially sleeved outside the linear bearing, the linear bearing and the fixed sleeve are elastically connected through the horizontal vibration isolation spring; the vibrating rod is slidably connected to the linear bearing.

[0012] Through this solution, the fixed sleeve is fixed to the driving device, the linear bearing allows the vibration amplitude of the vibrating rod in the vertical direction, and the horizontal vibration isolation spring can isolate the vibration on the linear bearing from being transmitted to the fixed sleeve.

[0013] Preferably, the inner diameter of the fixing sleeve is smaller than the outer diameter of the linear bearing but larger than the inner diameter of the linear bearing, and the linear bearing is slidably connected to the fixing sleeve.

[0014] Through this solution, the linear bearing is allowed to slide in any horizontal direction in the fixed sleeve, so that the linear bearing is in flexible contact with the fixed sleeve all around, which helps to isolate vibrations in various horizontal directions.

[0015] Preferably, a plurality of the vibration motors are evenly mounted on the mounting plate, and a plurality of counterweights are provided on the mounting plate.

[0016] Through this solution, the vibration effect is improved while reducing the serious wear of equipment caused by unbalanced pressure on a certain side, thereby increasing the service life of the device.

[0017] Preferably, the vibrating rod includes a vibrating sleeve and a support rod, the support rod is slidably connected to the vibrating sleeve, the bottom of the support rod always extends out of the vibrating sleeve, the top of the support rod is connected to the top of the vibrating sleeve through a fixed release mechanism, and the mounting plate is fixed to the vibrating sleeve.

[0018] Through this solution, after the fixed release mechanism fixes the support rod to the vibrating sleeve, the support rod can vibrate in the vertical direction to facilitate the device to vibrate areas with deeper depths; when the fixed release mechanism releases the support rod, the support rod can reduce the vibration amplitude in the vertical direction due to the sliding connection with the vibrating sleeve, avoiding the vibration rod from damaging the base structure or causing the bottom surface to vibrate and causing the sleeper to shift during vibration operations in shallow areas, further improving the stability during the vibration process.

[0019] Preferably, a support plate is horizontally mounted on the top of the support rod, and when the bottom of the support rod is flush with the bottom of the vibrating sleeve, the support plate can reach the top of the driving device.

[0020] Through this solution, the support plate can increase the contact area with the driving device, thereby reducing the damage to the driving device when it hits the top of the driving device; after the support plate hits the driving device, it can transfer part of the vibration to the driving device to serve as a warning, reminding construction personnel to lift the driving device to avoid the vibration sleeve hitting the base mechanism and causing damage to the base structure.

[0021] Preferably, a receiving groove is provided on the top of the mounting plate, and the supporting plate can move into the receiving groove.

[0022] Through this solution, after the support plate enters the accommodating groove, the fixing effect of the support rod can be improved, thereby ensuring the vibration effect of the support rod.

[0023] Preferably, the fixed release mechanism comprises a blocking rod, which is rotatably connected to the mounting plate and can block one end of the blocking rod to the top of the support rod, and the other end of the blocking rod extends out of the driving device and is provided with an adjustment handle.

[0024] Through this solution, the blocking rod rotates to the top of the support rod to press the support rod, so that the support rod and the vibrating sleeve can vibrate synchronously; the blocking rod rotates to one side of the support rod to release the support rod, so that the support rod can slide up and down, reducing its vibration amplitude in the vertical direction.

[0025] Preferably, a plurality of ribs are evenly arranged on the outer wall of the vibrating sleeve, and the ribs are arranged along the axial direction of the vibrating sleeve.

[0026] Through this solution, the provision of ribs can increase the range of vibration and ensure that the surrounding concrete vibrates together during the vibration process; and the ribs can increase the strength of the vibration sleeve to avoid continuous vibration collision causing the vibration sleeve to break.

[0027] According to an embodiment of the present disclosure, the device has a simple and practical structure, can meet the high-precision requirements during the pouring and vibration of turnout concrete, avoids the displacement of sleepers or rails caused by vibration transmission, and ensures the safety of construction workers and turnouts.

[0040] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0041] Example

[0042] like Figures 1 to 6 As shown, the vibrating device for pouring turnout concrete in this embodiment includes a driving device 100 and a vibrating rod 200. The driving device 100 drives the vibrating rod 200 to vibrate. The driving device 100 is provided with a handle 110. The driving device 100 is provided with a vibration isolation mechanism and a vibration motor 121. The vibrating rod 200 is installed in the driving device 100 through the vibration isolation mechanism, and the vibration motor 121 is installed on the vibrating rod 200.

[0043] Through the scheme of this embodiment, the handle 110 is manually pulled to place the device, and during the vibration motor 121 drives the vibrating rod 200 to vibrate, the vibration amplitude transmitted to the driving device 100 will be greatly weakened due to the existence of the vibration isolation mechanism, thereby reducing damage to human organs and avoiding vibration from being transmitted to the sleepers and rails through the human body, thereby ensuring the accuracy of the position of the sleepers and rails and improving the safety of construction.

[0044] In this embodiment or other embodiments, the vibration isolation mechanism includes a vertical vibration isolation spring 131 and a horizontal vibration isolation ring 140. A mounting plate 211 is provided on the top of the vibrating rod 200. The vibration motor 121 is installed on the top of the mounting plate 211. The vertical vibration isolation spring 131 is supported to the bottom of the mounting plate 211. The horizontal vibration isolation ring 140 is fixed to the through hole at the bottom of the driving device 100. The vibrating rod 200 passes through the horizontal vibration isolation ring 140 and extends out of the driving device 100.

[0045] The vertical vibration isolation spring 131 and the horizontal vibration isolation ring 140 can isolate the driving device 100 from the vibrating rod 200 to avoid direct rigid contact between the two, thereby filtering vibrations in the vertical and horizontal directions and reducing the transmission of vibrations.

[0046] In this embodiment or other embodiments, the horizontal vibration isolation ring 140 includes a fixed sleeve 142, a linear bearing 143 and a horizontal vibration isolation spring 141. The fixed sleeve 142 is coaxially sleeved on the outside of the linear bearing 143. The linear bearing 143 and the fixed sleeve 142 are elastically connected through the horizontal vibration isolation spring 141; the vibrating rod 200 is slidably connected to the linear bearing 143.

[0047] There are several horizontal vibration isolation springs 141 and they are arranged around the linear bearing 143. The fixed sleeve 142 is fixed to the driving device 100. The linear bearing 143 allows the vibrating rod 200 to be displaced in the vertical direction. The horizontal vibration isolation springs 141 can isolate the vibration on the linear bearing 143 from being transmitted to the fixed sleeve 142.

[0048] In this embodiment or other embodiments, the inner diameter of the fixing sleeve 142 is smaller than the outer diameter of the linear bearing 143 but larger than the inner diameter of the linear bearing 143, and the linear bearing 143 is slidably connected to the fixing sleeve 142. The linear bearing 143 is allowed to slide in any horizontal direction in the fixing sleeve 142, so that all four sides of the linear bearing 143 are in flexible contact with the fixing sleeve 142, thereby helping to isolate vibrations in various horizontal directions.

[0049] In this embodiment or other embodiments, a plurality of vibration motors 121 are evenly mounted on the mounting plate 211, and a plurality of counterweights 122 are disposed on the mounting plate 211, which can improve the vibration effect while reducing the serious problem of equipment wear caused by unbalanced pressure on a certain side, thereby increasing the service life of the device. When the plurality of vibration motors 121 work at the same time, they will maintain synchronous motion due to resonance, thereby increasing the amplitude.

[0050] In this embodiment or other embodiments, the vibrating rod 200 includes a vibrating sleeve 210 and a support rod 220, the support rod 220 is slidably connected to the vibrating sleeve 210, the bottom of the support rod 220 always extends out of the vibrating sleeve 210, the top of the support rod 220 is connected to the top of the vibrating sleeve 210 through a fixed release mechanism 230, and the mounting plate 211 is fixed to the vibrating sleeve 210.

[0051] After the fixing release mechanism 230 fixes the support rod 220 to the vibrating sleeve 210, the support rod 220 can vibrate in the vertical direction, and the bottom of the support rod 220 is fully extended to facilitate the device to vibrate a deeper area;

[0052] When the fixed release mechanism 230 releases the support rod 220, the support rod 220 can greatly reduce the vibration amplitude in the vertical direction due to the sliding connection with the vibrating sleeve 210, thereby avoiding the vibration rod 200 hitting the base structure (such as a soil layer or a sand layer) at a shallow depth, thereby destroying the base structure or causing the bottom surface to vibrate, which may cause the sleeper to shift, thereby further improving the stability during the vibration process.

[0053] Since the concrete layer to be poured at the turnout is relatively shallow (usually 30cm-50cm), the vibrator cannot be fully extended into the concrete. If it completely touches the ground, the huge vibration will cause the sleeper or rail to shift.

[0054] In this embodiment or other embodiments, a support plate 221 is horizontally installed on the top of the support rod 220. When the bottom of the support rod 220 is flush with the bottom of the vibrating sleeve 210, the support plate 221 can abut against the top of the driving device 100. The support plate 220 can increase the contact area with the driving device 100, thereby reducing the damage to the driving device when abutting against the top of the driving device 100; after the support plate 221 abuts against the driving device 100, a part of the vibration can be transmitted to the driving device 100, so as to play a warning role, reminding the construction personnel to lift the driving device 100, and avoiding the vibrating sleeve 210 abutting against the base structure to cause damage to the base structure.

[0055] In this embodiment or other embodiments, a receiving groove 212 is provided on the top of the mounting plate 211, and the support plate 221 can move into the receiving groove 212. After the support plate 221 enters the receiving groove 212, the fixing effect of the support rod 220 can be improved, and the vibration effect of the support rod 220 can be improved, thereby ensuring that the support rod 220 and the vibrating sleeve 210 move synchronously.

[0056] In this embodiment or other embodiments, the fixed release mechanism 230 includes a blocking rod 231, which is rotatably connected to the mounting plate 211 and can enable one end of the blocking rod 231 to block the top of the support rod 220, and the other end of the blocking rod 231 extends out of the driving device 100 and is provided with an adjustment handle 232.

[0057] The blocking rod 231 rotates to the top of the support rod 220 to press the support rod 220, so that the support rod 220 and the vibrating sleeve 210 can vibrate synchronously; the blocking rod 231 rotates to one side of the support rod 220 to release the support rod 220, so that the support rod 220 can slide up and down, reducing its vibration amplitude in the vertical direction.

[0058] In other embodiments, a magnet or the like is disposed at the bottom of the blocking rod 231 so as to be temporarily adsorbed to the top of the support rod 220 or the top of the mounting plate 211 to prevent the blocking rod 231 from automatically shifting during vibration.

[0059] In this embodiment or other embodiments, a plurality of ribs 213 are evenly arranged on the outer wall of the vibrating sleeve 210. The ribs 213 are arranged along the axial direction of the vibrating sleeve 210. The arrangement of the ribs 213 can increase the range of vibration and ensure that the surrounding concrete vibrates together during the vibration process; and the ribs 213 can increase the strength of the vibrating sleeve 210 to avoid the vibration sleeve from being broken due to continuous vibration collision.

[0060] According to this embodiment, the device has a simple and practical structure, can meet the high-precision requirements during the pouring and vibration of turnout concrete, avoids the displacement of sleepers or rails caused by vibration transmission, and ensures the safety of construction workers and turnouts.

[0061] Although some specific embodiments of the present invention have been described in detail by way of example, it will be appreciated by those skilled in the art that the above examples are for illustration only and are not intended to limit the scope of the present invention. It will be appreciated by those skilled in the art that the above embodiments may be modified without departing from the scope and spirit of the present invention.
