Description

Technical Field

[0001] This application relates to the field of railway engineering machinery, and in particular to a ground-end reversing and fixing protection device for the upper cable of a railway car shifter. Background Technology

[0002] The car-pushing machine is a key piece of equipment in the tippler unloading system. It is mainly used to pull heavy railway car trains and push individual heavy cars into the tippler for positioning. It is widely used in bulk material conveying systems in ports, power plants, steel mills and other places.

[0003] The car-shifting machine requires an upper cable connection. The ground end of the upper cable is fixed to this device, and the upper end is fixed to the drum / reel via a guide frame. The traditional method of fixing the cable using U-shaped shackles has problems of wear and breakage due to the frequent twisting and stretching of the cable when the car-shifting machine passes back and forth on the track and the cable is fixed to the ground.

[0004] The existing technology mainly has the following problems:

[0005] The process involves excavating a civil engineering foundation next to the railway trackbed, pouring a cement base, and securing the cable with U-shaped clips. This requires excavating the railway trackbed to create a cement foundation to avoid damaging it. To accommodate the narrow width of the railway trackbed, L-shaped metal bends and U-shaped clips are used to fix the cable to the cement foundation. However, relying solely on the U-shaped clips for cable tension makes it prone to slippage, and the high degree of cable bending makes it susceptible to damage. L-shaped conduits easily accumulate water and sand, which are difficult to clean. Water accumulation can cause corrosion, and sand and gravel can abrade the cable. Furthermore, the L-shaped bends at the cable inlet and outlet can easily cause friction damage to the cable when it is redirected.

[0006] Therefore, a ground-end reversing and fixing protection device for the cable is needed to solve the following problems: 1. Reliable cable fixing and reversing; 2. Damage to the cable caused by water corrosion and debris accumulation due to defects in the device itself; 3. Wear and breakage of the cable caused by frequent twisting and stretching when the car-pulling machine passes the cable ground-fixed reversing position on the track. Utility Model Content

[0007] To address the aforementioned problems, achieve fixed protection and reversing of the ground end of the overhead cable, and improve the cable's service life, this application provides a reversing and fixed protection device for the ground end of the overhead cable of a railway car shifter.

[0008] The technical solution of the ground end reversing and fixing protection device for the upper cable of the railway car shifter provided in this application is as follows.

[0009] A ground-end redirection and fixing protection device for the overhead cable of a railway car shifter includes: a fixed connecting seat for connecting to the rail, one end of which is provided with a cable guiding device for guiding the cable; the cable guiding device includes a U-shaped base, a U-shaped guide groove is provided inside the U-shaped base, and arc-shaped cable guide grooves are provided at the ends of the U-shaped guide groove in both the front and rear directions of the rail; a clamping device for clamping the cable is provided at the beginning end of the U-shaped guide groove.

[0010] By adopting the above technical solution, the cable guiding device is connected to the rail via a fixed connecting seat, eliminating the need for excavation of the railway subgrade and the construction of a cement foundation, thus avoiding damage to the railway subgrade. Through the U-shaped guide groove and the arc-shaped guide cable groove, the cable can first pass through the U-shaped guide groove guided by the U-shaped base. The clamping device locks the cable and wraps it around the U-shaped base, utilizing the cable's own curvature to reduce the clamping force, making the cable more secure and preventing it from loosening. Then, guided by the arc-shaped guide cable groove, the cable's path is smooth with minimal bends. The arc-shaped guide cable groove restricts the cable's bending, preventing excessive bending that could cause internal core compression and breakage. The guide bridge's inclination is adjustable, ensuring the cable smoothly enters the cable tray along the track.

[0011] Optionally, the fixed connecting seat is located below the rail, and a pressure block is connected to the fixed connecting seat by bolts, the pressure block pressing against the lower edge of the rail.

[0012] By adopting the above technical solution, the fixed connection is set under the rail, making full use of the gap and not affecting the normal use of the rail itself. The connection to the rail is made by tightening the bolts so that the pressure block presses against the lower edge of the rail. The installation method is simple and easy to operate.

[0013] Optionally, a notch is provided at the bottom of one end of the pressure block, and the other end of the pressure block is connected to the fixed connecting seat by bolts. The notch at one end of the pressure block presses down and hugs the lower edge of the rail.

[0014] By adopting the above technical solution, and through the opening of the notch on the pressure block, when the pressure block presses down on the rail, it can better cooperate with the lower edge of the rail, which is conducive to improving the installation stability of the fixed connection seat.

[0015] Optionally, a rubber pad is provided between the fixed connecting seat and the rail.

[0016] By adopting the above technical solution, the installation is facilitated by the setting of rubber pads, which helps to improve the reliability of bolt tightening. At the same time, an insulating pad layer is added between the fixed connection seat and the rail to insulate the fixed connection seat from the rail.

[0017] Optionally, the U-shaped base includes a U-shaped shell, and the U-shaped shell is hollow to form a U-shaped guide groove.

[0018] By adopting the above technical solution, the U-shaped guide groove can limit and guide the cable, allowing the cable to pass through the U-shaped guide groove and preventing the cable from being stretched, bent, or twisted arbitrarily.

[0019] Optionally, a top cover plate is bolted to the top of the U-shaped shell, and a side cover plate is provided on the bottom side of the U-shaped shell. The inner surface of the side cover plate is vertically formed with a groove for drainage.

[0020] By adopting the above technical solution, the top cover plate can prevent water, sand, and other debris from accumulating inside. Accumulated water is prone to corrosion, and sand can cause wear and tear on the cables. The top cover plate and side cover plate can be opened to clean the inside and prevent corrosion. It also has a drainage function. When the side cover plate is opened, external force can be used to assist in bending the cable so that it can pass smoothly through the U-shaped guide groove.

[0021] Optionally, the arc-shaped guide cable groove is located at one end of the U-shaped base near the fixed connection seat. The arc-shaped guide cable groove includes two opposite and spaced arc-shaped guide plates, and side baffles are provided on the sides of the two arc-shaped guide plates.

[0022] By adopting the above technical solution, the cable is guided to bend smoothly, avoiding excessive bending of the cable that could cause the internal core to be squeezed and break, and enter the cable tray along the line, so that the cable can extend smoothly along the railway direction.

[0023] Optionally, the arc-shaped guide cable groove further includes a plurality of rollers disposed above the arc-shaped guide plate between the two side baffles, and the plurality of rollers are arranged in an arc-shaped interval.

[0024] By adopting the above technical solution and setting up the idler rollers, the cable can be better supported and guided, reducing cable wear.

[0025] Optionally, the clamping device includes a clamping assembly, which includes a left clamping block and a right clamping block connected to each other by bolts. A clamping groove for clamping the cable is provided between the left clamping block and the right clamping block, and a clamping pad is provided in the clamping groove.

[0026] By adopting the above technical solution, the clamping device locks the cable and passes the cable around the U-shaped guide groove. The cable's own curvature reduces the force on the clamp, making the cable more secure and preventing it from loosening.

[0027] Optionally, the left and right clamping blocks have sliding grooves on both sides along the lateral direction. The clamping device also includes a slide rail frame set in a U-shaped guide groove. The slide rail frame includes two spaced side frames. The sliding grooves on both sides of the left and right clamping blocks slide in cooperation with the side frames. One end of the locking plate is bolted to the end of one side frame. The other end of the locking plate is open and bolted to the end of the other side frame.

[0028] By adopting the above technical solution, the clamping component adopts a sliding and fixed form, which facilitates disassembly, inspection and maintenance of cable concealment areas, and original installation and restoration.

[0029] In summary, this application includes at least the following beneficial effects:

[0030] 1. In this application, the cable guiding device is connected to the rail via a fixed connecting seat, eliminating the need for excavation of the railway subgrade to construct a cement foundation, thus avoiding damage to the railway subgrade. Through the setting of the U-shaped guide groove and the arc-shaped guide cable groove, the cable can first pass through the U-shaped guide groove guided by the U-shaped base. The clamping device locks the cable and wraps the cable around the U-shaped base. The cable's own curvature reduces the force on the clamp, making the cable more firmly fixed and preventing it from loosening. Then, guided by the arc-shaped guide cable groove, the cable's travel path is smooth with few bends. The arc-shaped guide cable groove can restrict the cable to bend smoothly, avoiding excessive bending of the cable that could cause internal core compression and breakage. The inclination of the guide bridge is adjustable, ensuring that the cable smoothly enters the cable tray along the track.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0050] The following is in conjunction with the appendix Figures 1 to 15 This application will be described in further detail.

[0051] This application discloses a ground-end redirection and fixing protection device for the upper cable of a railway car shifter.

[0052] Example 1

[0053] Reference Figures 1 to 12 A ground-end redirection and fixing protection device for the upper cable of a railway car shifter includes: a fixed connecting seat 1, a cable guiding device, and a clamping device.

[0054] The fixed connecting seat 1, which can be an I-beam, is used to connect with the rail 2. The fixed connecting seat 1 is located below the rail 2 and spans across the two rails 2. A pressure block 3 is connected to the fixed connecting seat 1 by bolts. The pressure block 3 presses against the lower edge of the rail 2. The fixed connection is located below the rail 2, making full use of the gap and not affecting the normal use of the rail 2 itself. The connection with the rail 2 is made by tightening the bolts so that the pressure block 3 presses against the lower edge of the rail 2. The installation method is simple and easy to operate.

[0055] A notch is provided at the bottom of one end of the pressure block 3, and the other end of the pressure block 3 is connected to the fixed connecting seat 1 by bolts. The notch at one end of the pressure block 3 presses down and hugs the lower edge of the rail 2. By providing the notch on the pressure block 3, when the pressure block 3 presses down on the rail 2, it can better cooperate with the lower edge of the rail 2, which is conducive to improving the installation stability of the fixed connecting seat 1.

[0056] A rubber pad is provided between the fixed connecting seat 1 and the rail 2. The rubber pad facilitates installation and improves the reliability of bolt tightening. At the same time, an insulating pad is added between the fixed connecting seat 1 and the rail 2 to insulate the fixed connecting seat 1 from the rail 2.

[0057] A cable guide device is fixedly connected to one end of the fixed connection seat 1 by welding, and is used to guide the cable 18.

[0058] The cable guiding device includes a U-shaped base, which includes a U-shaped housing 4. The U-shaped housing 4 is hollow to form a U-shaped guide groove 5. The U-shaped guide groove 5 can limit and guide the cable 18, allowing the cable 18 to pass through the U-shaped guide groove 5 and preventing the cable 18 from being stretched, bent, twisted, etc.

[0059] The top of the U-shaped housing 4 is bolted to a top cover plate 6, and the bottom side of the U-shaped housing 4 is provided with a side cover plate. The inside of the side cover plate has a vertical groove for drainage. The top cover plate 6 prevents water, sand, and other debris from accumulating inside. Water accumulation can cause corrosion, and sand can cause abrasion to the cable 18. The top cover plate 6 and the side cover plate can be opened to clean the inside and prevent corrosion. It also has a drainage function. When the side cover plate is opened, external force can be used to assist in bending the cable 18 to pass smoothly through the U-shaped guide groove 5.

[0060] At the end of the U-shaped guide groove 5, an arc-shaped guide cable groove 7 is provided in both the front and rear directions of the track. The arc-shaped guide cable groove 7 is located at the end of the U-shaped base near the fixed connection seat 1. The arc-shaped guide cable groove 7 includes two opposite and spaced arc-shaped guide plates 8. Side baffles 9 are provided on the sides of the two arc-shaped guide plates 8. The arc-shaped guide plates 8 are arc-shaped, and the side baffles 9 block and limit the movement on both sides, guiding the cable 18 to bend smoothly and change direction, avoiding excessive bending of the cable 18 that would cause the internal core to be squeezed and break, and prevent it from entering the cable tray along the line, so that the cable 18 extends smoothly along the railway direction.

[0061] The clamping device includes a clamping assembly 10, which comprises a left clamping block and a right clamping block connected to each other by bolts. A clamping groove 11 for clamping the cable 18 is formed between the left and right clamping blocks, and a clamping pad 12, which can be a rubber pad, is provided in the clamping groove 11. Sliding grooves 13 are formed laterally on both sides of the left and right clamping blocks. The clamping device also includes a slide rail frame 14 located at the first end of the U-shaped guide groove 5. The slide rail frame 14 includes two spaced side frames 15. The sliding grooves 13 on both sides of the left and right clamping blocks slide in cooperation with the side frames 15. One end of a locking plate 16 is bolted to the end of one side frame 15, and the other end of the locking plate 16 is open and bolted to the end of the other side frame 15. The clamping device locks the cable 18 and wraps the cable 18 around the U-shaped guide groove 5. The bending of the cable 18 itself reduces the clamping force, making the cable 18 more secure and preventing it from loosening. The clamping assembly 10 adopts a sliding fixing form, which facilitates the disassembly, inspection and maintenance of the cable 18 in the concealed location and its original installation and restoration.

[0062] In this application, the cable guiding device is connected to the rail 2 via a fixed connecting seat 1, eliminating the need for excavation of the railway subgrade to construct a cement foundation and avoiding damage to the railway subgrade. With the setting of the U-shaped guide groove 5 and the arc-shaped guide cable groove 7, the cable 18 can first pass through the U-shaped guide groove 5 guided by the U-shaped base. The clamping device locks the cable 18 and wraps the cable 18 around the U-shaped base. The bending of the cable 18 itself reduces the clamping force, making the cable 18 more firmly fixed and preventing it from loosening. Then, guided by the arc-shaped guide cable groove 7, the cable 18 travels smoothly with few bends. The arc-shaped guide cable groove 7 can restrict the cable 18 to bend smoothly, avoiding excessive bending of the cable 18 that could cause the internal core to be squeezed and broken. The inclination of the guide bridge is adjustable, ensuring that the cable 18 smoothly enters the cable tray along the track.

[0063] Example 2

[0064] Reference Figures 13 to 15A ground-end redirection and fixing protection device for the upper cable of a railway car shifter includes all the contents of Embodiment 1, except that the arc-shaped guide cable groove 7 also includes a plurality of rollers 17 arranged above the arc-shaped guide plate 8 between the two side baffles 9, and the plurality of rollers 17 are arranged in an arc-shaped interval. Since the cable 18 is supported and guided by the rollers 17, it is also possible to have only rollers 17 and remove the arc-shaped guide plate 8. By setting the rollers 17, the cable 18 can be better supported and guided, and the wear of the cable 18 can be reduced.
