Description

Technical Field

[0001] This application relates to the technical field of railway engineering, and particularly relates to an installation tool for rail elastic fasteners. Background Art

[0002] With the development of society, high-speed railway transportation has become the common goal pursued by countries around the world. In order to meet the requirements of high smoothness, high durability, and comfort of high-speed railways, it is necessary to adopt and develop ballastless tracks with less maintenance. Since the railway tracks are installed on the sleepers, and the sleepers have to bear high loads for a long time, the sleepers must have sufficient strength while ensuring the firmness of the connection between the sleepers and the tracks.

[0003] The function of railway fasteners is to firmly fix the railway tracks on the sleepers. Among them, the elastic fasteners are boltless fasteners, and two elastic fasteners on the same rail seat are arranged staggeredly, and their axes are not on the same straight line. Such elastic fasteners are suitable for ballastless tracks. While meeting the various performance requirements of high-speed railways for the fastener system, they also have significant advantageous features: not only can the complete pre-assembly of the fastener system be realized, reducing the workload of on-site fastener installation and improving the track laying efficiency; but also the maintenance amount of the fastener system can be greatly reduced, significantly reducing the line maintenance cost.

[0004] In the related art, for the above-mentioned elastic fasteners, special pure manual installation tools and automated installation equipment are generally used for installation. However, during on-site construction, since the clamping force of the elastic strip is generated by the elastic deformation of the elastic strip itself, when workers use pure manual tools for construction, it consumes a large amount of manpower, has low construction efficiency, is difficult to guarantee the work quality, is also a great test of the physical strength of construction workers, has a very high labor intensity, slow construction progress, increases the construction budget; the automated installation equipment is too large in volume, difficult to carry, and is not convenient when dealing with the installation of some scattered small parts caused by installation problems on-site, increasing the labor intensity, and there is no support for the fasteners on the head and tail rails, resulting in inability to install.

[0040] To make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are some, but not all, of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts shall fall within the protection scope of the present application.

[0041] As shown in Figure 1 , the embodiments of the present application provide an installation tool for a track elastic rail clip. The functions of the track elastic rail clip are as follows: install the base plate 2 at the rail-bearing part of the track slab, fix the base plate 2 to the track slab with anchor bolts, install an insulating buffer pad on the rail-bearing groove of the base plate 2, push the rail into the rail-bearing groove of the base plate 2, and fasten the rail and the base plate 2 with the elastic rail clip 4.

[0042] The installation tool according to the embodiment of the present application is used to press the elastic clip fastener 4 into the tie plate 2 to fasten the rail and the tie plate 2. The installation tool includes a pull plate 1, a feeding mechanism 3 and a driving mechanism 5. One end of the pull plate 1 is provided with a clamping end 10 for clamping on the tie plate 2 of the track; the feeding mechanism 3 is adapted to the elastic clip fastener 4; the driving mechanism 5 is arranged on the pull plate 1, and the driving mechanism 5 is connected to the feeding mechanism 3 and is used to drive the feeding mechanism 3 to move towards the direction close to the clamping end 10 to push the elastic clip fastener 4 until the elastic clip fastener 4 is pressed into the tie plate 2; or move in the direction away from the clamping end 10 to release the elastic clip fastener 4.

[0043] The working principle of the installation tool according to the embodiment of the present application is as follows:

[0044] Refer to Figure 6 and Figure 7 As shown, first, the clamping end 10 at one end of the pull plate 1 is clamped in the rail bearing groove of the tie plate 2 of the track to fix the pull plate 1 on the tie plate 2. Then, the driving mechanism 5 drives the feeding mechanism 3 to move towards the direction close to the clamping end 10, so that the feeding mechanism 3 presses on the elastic clip fastener 4 and pushes the elastic clip fastener 4 until the elastic clip fastener 4 is pressed into the tie plate 2, completing the installation of the elastic clip fastener 4; after the installation is completed, the driving mechanism 5 drives the feeding mechanism 3 to move in the direction away from the clamping end 10 to release the elastic clip fastener 4, facilitating the installation of the next elastic clip fastener 4.

[0045] The installation tool according to the embodiment of the present application can achieve the one-time installation of the elastic clip fastener 4. The tool itself is light in weight and convenient to move. Compared with the weight of automated equipment, it reduces the labor intensity of workers; moreover, the equipment is easy to operate, and the elastic clip fastener 4 can be buckled by holding the installation tool, which is more labor-saving than a pure manual tool, improves the on-site construction efficiency, and well solves the defect that the elastic clip fasteners 4 at the head and tail of the rail cannot be installed during the installation of the sleeper, realizing the full installation of the elastic clip fasteners 4.

[0046] Optionally, as shown in Figure 2 the driving mechanism 5 according to the embodiment of the present application includes a screw 50 and a driver. The screw 50 is screwed on the pull plate 1, and one end of it is connected to the feeding mechanism 3; the driver is connected to the other end of the screw 50 and is used to drive the screw 50 to rotate to drive the guide member 51 to reciprocate on the pull plate 1.

[0047] The driver in the embodiment of the present application is an electric wrench. One end of the screw 50 is connected with a bolt. The electric wrench is connected to the bolt to provide power. The electric wrench drives the screw 50 to rotate, converting the rotary motion into a linear motion, generating an axial motion and a large axial force with the torque rotation, pushing the elastic clip fastener 4 into the designed installation position. By providing the power required for the elastic clip fastener 4 to be buckled through the driving mechanism 5, the installation purpose is achieved.

[0048] Preferably, referring to Figure 2 As shown, the driving mechanism 5 of the embodiment of the present application further includes a guide member 51. The guide member 51 is connected to the pull plate 1, and a through hole is formed in the guide member 51. One end of the screw rod 50 passes through the through hole and is connected to the pushing mechanism 3.

[0049] Since the screw rod 50 needs to perform a linear motion for a certain distance, in order to better stabilize the screw rod 50, one end of the screw rod 50 close to the pushing mechanism 3 is fixed by the guide member 51 to prevent the screw rod 50 from generating vertical displacement during movement.

[0050] Furthermore, referring to Figure 3 and Figure 4 As shown, the driving mechanism 5 further includes a guide member 51 and a bearing 501. The guide member 51 is slidably disposed on the pull plate 1, and a through hole is formed in the guide member 51; the bearing 501 is received in the through hole and is connected to the guide member 51, and one end of the screw rod 50 passes through the bearing 501 and is connected to the pushing mechanism 3.

[0051] In order to provide a greater driving force to the pushing mechanism 3, through the cooperation of the screw rod 50 and the bearing 501, the driving force of the screw rod 50 is improved. Moreover, since the screw rod 50 is connected to the bearing 501, the weight of the screw rod 50 is increased, and the stability of the screw rod 50 during movement needs to be achieved through the guide member 51.

[0052] Moreover, two bearings 501 are provided in the embodiment of the present application. One of the two bearings 501 away from the pushing mechanism 3 is a thrust bearing 502, and the other is a ball bearing 503. The thrust bearing 502 can withstand a greater thrust. When the screw rod 50 performs a pushing movement, it withstands a large thrust; when the screw rod 50 retreats, since the supporting force required for the screw rod 50 to retreat is not large, the ball bearing 503 provides the supporting force.

[0053] Furthermore, referring to Figure 3 and Figure 4 As shown, a guide groove 11 penetrating the pull plate 1 is formed in the pull plate 1; the guide member 51 includes a connecting member 510 and a guide rod 511, and the connecting member 510 is connected to the bearing 501; the guide rod 511 is connected to the connecting member 510 and movably penetrates through the guide groove 11.

[0054] The guide rod 511 of the embodiment of the present application is movably disposed on the connecting member 510 and rollably penetrates through the guide groove 11, reducing the friction between the guide rod 511 and the pull plate 1, making it easier for the guide rod 511 to reciprocate on the pull plate 1 under the drive of the bearing 501, and improving the installation efficiency of the elastic clip fastener 4.

[0055] Further, referring to Figure 4As shown, the driving mechanism 5 further includes a limiting component 52. The limiting component 52 is arranged on the pulling plate 1 and is used to limit the advancement of the screw rod 50.

[0056] The installation tool of the embodiment of the present application can design the advancement distance of the screw rod 50 according to the preset advancement distance of the elastic clip fastener 4, so as to limit the distance of the screw rod 50 through the limiting component 52, thereby reducing the installation time of the elastic clip fastener 4 and improving the installation efficiency.

[0057] Furthermore, referring to Figure 4 As shown, the limiting component 52 includes a limiting disk 520. The limiting disk 520 is fixed on the pulling plate 1, and a threaded hole is opened on the limiting disk 520; the screw rod 50 is screwed into the limiting disk 520, and a resisting member 504 is connected to one end of the screw rod 50. The resisting member 504 is used to abut against the limiting disk 520 to limit the advancement of the screw rod 50.

[0058] The resisting member 504 connected to one end of the screw rod 50 in the embodiment of the present application is a bolt, which cooperates with the electric wrench and plays a role of limiting at the same time. When the resisting member 504 moves with the screw rod 50 to abut against the limiting disk 520, the advancement of the screw rod 50 will be restricted, which also indicates that the installation of the elastic clip fastener 4 has been completed.

[0059] Furthermore, referring to Figure 4 As shown, the limiting disk 520 includes a first disk body 5200 and a second disk body 5201. The first disk body 5200 is fixed on the pulling plate 1; the second disk body 5201 is arranged on the screw rod 50 at an interval from the first disk body 5200; the resisting member 504 is used to abut against the second disk body 5201.

[0060] Since the thicknesses of the first disk body 5200 and the second disk body 5201 are small, materials and weight can be saved. However, this also results in fewer turns of the threads inside the first disk body 5200 and the second disk body 5201, and they cannot play a better stabilizing role with the screw rod 50. Therefore, in order to prevent the screw rod 50 from rotating and slipping, two spaced-apart disk bodies are designed, which is equivalent to increasing the number of turns of the threads and reducing the problems of more material consumption and greater weight caused by using a single thick disk body.

[0061] Optionally, referring to Figure 1 and Figure 5 As shown, the pushing mechanism 3 includes a pushing plate 30, and a groove 300 adapted to the elastic clip fastener 4 is opened on the pushing plate 30.

[0062] The elastic clip fastener 4 in the embodiment of the present application is in a W shape, and the groove 300 on the pushing plate 30 is adapted to the two bending parts of the W-shaped elastic clip fastener 4, which can realize simultaneous and synchronous advancement and maintain the stability and accuracy of the pushing of the elastic clip fastener 4.

[0063] Optionally, referring toFigure 1 and Figure 2 As shown in Figure 2 , a clamping groove 100 is formed on the clamping end 10, and the clamping groove 100 is used to be buckled on the tie plate 2.

[0064] The clamping groove 100 on the clamping end 10 is adapted to the rail-bearing groove of the tie plate 2 and is buckled in the rail-bearing groove to fix the pull plate 1 on the tie plate 2.

[0065] The installation tool further includes pressing plates which are respectively arranged on both sides of the pull plate and cooperate with the clamping groove 100 to press on the tie plate 2 so as to stably and horizontally place the installation tool on the tie plate 2.

[0066] The installation tool of the present application is convenient to operate and has a low failure rate. Using the installation tool of the present application to perform the installation operation of the staggered elastic rail fastening 4 can achieve high-efficiency and mechanized operation, ensure the accurate installation of the elastic rail fastening 4 in place, save manpower, reduce labor intensity and improve work efficiency.
