[0035] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0036] Please also read Figures 1 to 5, now the present invention provides a device for preventing bending of guide plates of tamping machines. The device comprises two sets of guide plate fixing frames 1, two sets of guide plates 2 and two sets of anti-bending components 3. The two sets of guide plate fixing frames 1 are used to connect tamping machines. A receiving chamber 11 is formed inside the guide plate fixing frames 1. The receiving chamber 11 is provided with an opening 12 on one side of the hammer rod. The openings 12 of the two sets of guide plate fixing frames 1 are arranged opposite to each other. The two sets of guide plates 2 are respectively connected to one side of the opening 12 of the two sets of guide plate fixing frames 1. The two sets of guide plates 2 enclose a guiding space for guiding the reciprocating movement of the hammer rod. The guide plate 2 has a front and a back, the front faces the hammer rod 4 and the back faces the guide plate fixing frame 1. The two sets of anti-bending components 3 are respectively arranged in the two sets of receiving chambers 11, and one end is used to abut against the inner wall of the guide plate fixing frame 1 and the other end is used to abut against the back of the guide plate 2. The anti-bending components 3 are used to support and fix the guide plate 2 and prevent bending.

[0037] Compared with the prior art, the device for preventing bending of a tamping machine guide plate provided by the present invention completely solves the problem of severe bending of the hammer rod 4 caused by collision of adjacent hammer heads, so that the guide plate 2 always maintains a stable posture without bending or deformation, thereby extending its service life.

[0038] In some embodiments, see Figures 1 to 5 The anti-bending component 3 is T-shaped and the area of ​​one end face for abutting the back of the guide plate 2 is larger than the area of ​​one end face for abutting the guide plate fixing frame 1. Anti-wear pads 5 are provided on both end faces of the anti-bending component 3. The anti-wear pads 5 are in frictional contact with the guide plate 2 and the guide plate fixing frame 1. The anti-bending component 3 can play a good supporting role. It can be made of rigid material and can resist a certain amount of deformation, thereby preventing the guide plate 2 from being deformed. Secondly, it plays a fixing role, abutting the guide plate 2 and the guide plate fixing frame 1 against each other to form an integral structure, so that the self-strength of the guide plate 2 can be greatly improved, which is conducive to preventing bending deformation.

[0039] In this embodiment, the T-shape of the anti-bending component 3 is in a "lying" state or after being rotated 90°. When installing, it can be clamped inside the guide plate fixing frame 1. The guide plate fixing frame 1 is a frame structure, which is easy to be assembled and installed with the anti-bending component 3. After the anti-bending component 3 is successfully installed, it will not move, which is equivalent to being limited in this position, which is conducive to playing a supporting and guiding role.

[0040] In order to further improve the contact friction between the anti-bending component 3 and the guide plate fixing frame 1 and the guide plate 2, an anti-wear pad 5 is provided. The anti-wear pad 5 has a certain friction force and can fit or cling to the guide plate 2 and the guide plate fixing frame 1 to prevent the anti-bending component 3 from slipping, falling, etc., causing the guide plate 2 to bend and deform. The anti-wear sticker can be torn off or pasted, which is convenient for operation, thereby improving the flexibility and convenience of operation.

[0041] In some embodiments, see Figures 1 to 5 The anti-bending component 3 includes a first abutting portion 31, a telescopic portion 32, and a second abutting portion 33 arranged in sequence from one end to the other end. One end of the first abutting portion 31 is used to abut against the inner wall of the guide plate fixing frame 1; one end of the telescopic portion 32 is threadedly connected to the other end of the first abutting portion 31; one end of the second abutting portion 33 is used to abut against the back of the guide plate 2, and the other end is threadedly connected to the other end of the telescopic portion 32. The thread rotation directions of the two ends of the telescopic portion 32 are opposite, and the thread rotation directions of the first abutting portion 31 and the second abutting portion 33 are opposite. Screwing the telescopic portion 32 is used to adjust the distance between the first abutting portion 31 and the second abutting portion 33, thereby adjusting the fixing or supporting position of the guide plate 2. In order to be able to adjust the length of the anti-bending component 3 (the length is along the length direction of the guide plate fixing frame 1), it can be adapted to the fixing or supporting requirements of the guide plate 2 at different positions (referring to the length direction of the guide plate fixing frame 1). When the guide plate 2 is in a relatively loose state, the telescopic portion 32 can be screwed to adjust the guide plate 2 so as to be pushed and fixed.

[0042] Specifically, in this embodiment, the telescopic portion 32 is a sleeve structure with internal threads of opposite rotation directions at both ends, while one end of the first abutment portion 31 and the second abutment portion 33 are respectively provided with external threads of opposite rotation directions, and the internal threads and the external threads are conveniently screwed together.

[0043] In order to accurately monitor the position or posture of the guide plate 2, in some embodiments, refer to Figures 1 to 5 A monitor 6 is connected to the guide plate fixing frame 1, and the monitor 6 is used to monitor the position of the guide plate 2 in real time. By using the monitor 6, the parameters of the tamping machine can be accurately controlled and accurate tamping can be achieved. The signal detected by the monitor 6 can be transmitted to the outside world, so that the information detected by the monitor 6 can be seen at a location far away from the tamping machine, and remote monitoring can be achieved. When the position or posture of the guide plate 2 changes, it can be seen by the outside world at the first time, which is conducive to timely control of tamping information.

[0044] In some embodiments, see Figures 1 to 5The monitor 6 includes a connecting part 61, a rotating rod 62, a plurality of slide rails 63, a plurality of sliders 64 and a plurality of sensors 65. One end of the connecting part 61 is used to connect to the tamping machine, and the other end is provided with a rotating shaft 66, on which a bearing 67 is coaxially provided. The rotating rod 62 is arranged horizontally, and one end is connected to the bearing 67 and can rotate circumferentially around the rotating shaft 66 in a horizontal plane with the help of the bearing 67. The plurality of slide rails 63 are sequentially arranged on the rotating rod 62 along the axial direction of the rotating rod 62. The plurality of sliders 64 are respectively and one by one slidably connected to the plurality of slide rails 63, and the sliding direction of the sliders 64 is along the axial direction of the rotating rod 62. The plurality of sensors 65 are respectively and one by one connected to the plurality of sliders 64, and are used to detect toward the two groups of guide plates 2 to monitor the position of the guide plates 2 in real time. The monitoring position of the sensor 65 is adjusted with the help of the rotating rod 62 and the slider 64. The detection direction of the sensor 65 can be adjusted on the rotating rod 62, such as one end of the sensor 65 is connected to the slider 64 by a ball joint.

[0045] Specifically, the sensor 65 in this embodiment is a displacement sensor 65 or a position sensor 65 in the prior art, which can detect the position information of the guide plate 2 in real time. If the position changes or moves, the staff can know it at the first time.

[0046] In order to send out an alarm signal immediately to alert the staff, in some embodiments, please refer to Figures 1 to 5 , the sensor 65 is electrically connected to the controller 7 and the alarm 8, and the sensor 65 sends a detection signal to the controller 7 in real time. If the sensor 65 detects that the position of the guide plate 2 has moved, the controller 7 instructs the alarm 8 to send an alarm signal. The controller 7 in this embodiment uses a prior art product, which can be connected to the sensor 65 and analyze the received signal. If it is determined that the received signal has changed compared with the historical signal, it is considered that the position of the guide plate 2 has moved, and deformation may exist. At this time, the controller 7 sends a command to the alarm 8 to indicate an alarm. The controller 7 is an electronic device with a PLC module, a control circuit, etc., which can realize the functions and effects mentioned above. The alarm 8 can use an audible and visual alarm 8.

[0047] In order to remotely receive information such as whether the guide plate 2 is displaced or deformed, in some embodiments, refer to Figures 1 to 5 The monitor 6 is electrically connected to a wireless communication module, and the anti-bending device of the tamping machine guide plate 2 also includes a mobile terminal 9 wirelessly connected to the monitor 6, and the mobile terminal 9 can receive a signal from the monitor 6. The mobile terminal 9 has a display screen that can display the monitored information.

[0048] Specifically, the mobile terminal 9 is a handheld remote control, which wirelessly communicates with the monitor 6 through wireless communication signals such as 4G. The position information of the guide plate 2 can be viewed in real time on the mobile terminal 9, thereby better ensuring that the guide plate 2 is not deformed and the operating position of the hammer rod 4.

[0049] In order to provide lighting when the guide plate 2 or the tamping machine is used at night, in some embodiments, see Figures 1 to 5 , the rotating rod 62 is placed above, below or to the side of the guide plate 2, and a plurality of illuminators 10 are evenly distributed on the rotating rod 62 along its axial direction. The illuminators 10 are used to illuminate the tamping machine and the illuminator direction can be adjusted. In this embodiment, the position of the rotating rod 62 should be adaptively adjusted according to the position of the hammer rod 4 so that the two do not contact or interfere with each other. When the hammer rod 4 moves back and forth in the up and down directions, the rotating rod 62 can be set to the side of the hammer rod 4, and then the detection direction of the sensor 65 can be adjusted, so that the position of the guide plate 2 can also be detected. In short, it should be adjusted reasonably to avoid the intersection of the running trajectories of the two and cause mutual influence. The illuminator 10 is in a long strip shape, and its irradiation direction can be adjusted.

[0050] Preferably, a photovoltaic power supply component (not shown in the figure) is installed on the tamping machine, and the power output end of the photovoltaic power supply component is connected to the above-mentioned load (such as the lighting lamp 10, the sensor 65, etc.), so that power supply can be achieved through solar energy, which reduces the use of municipal electricity and saves energy.

[0051] In some embodiments, see Figures 1 to 5 The rotating rod 62 is also provided with a monitor 68 for real-time monitoring of the image and deformation of the hammer rod 4. The monitor 68 is electrically connected to the controller 7. The controller 7 has a memory suitable for receiving images or videos taken by the monitor 68 and a display suitable for displaying the taken images or videos.

[0052] In some embodiments, see Figures 1 to 5 The guide plate 2 blocks the opening 12 on the guide plate fixing frame 1, and together with the guide plate fixing frame 1, forms a semi-enclosed or closed chamber, and the anti-bending component is placed inside the semi-enclosed or closed chamber. The chamber is set in this embodiment to facilitate the installation of the anti-bending component 3 of the present application, which plays a good role in fixing and supporting the guide plate 2.

[0053] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
