Description

Technical Field

[0001] This invention relates to the field of railway laying, specifically to a railway track hoisting device. Background Technology

[0002] Railway tracks typically consist of two parallel rails, which are placed on sleepers and secured by rail braces, fasteners, rail clamps, rail clips, elastic clips, and railway spikes. Rails are generally long and narrow in shape, like an I-beam. Figure 9 As shown. When laying railway tracks, they are usually spliced ​​together in sections of equal length, and the track gauge between the two rails is always the standard gauge. The transportation and lowering of the rails require the use of hoisting equipment.

[0003] However, the current hoisting equipment has the following problems in the process of hoisting and lowering railway rails: 1. The connection between the railway rail and the clamps of the hoisting equipment and the release of the clamps after lowering both require manual operation, resulting in low overall work efficiency. Moreover, the hoisting is often carried out one by one on a single rail basis, which increases the cost and time of hoisting.

[0004] 2. During the process of lowering the rails onto the sleepers, it is difficult to keep the rails stable, resulting in a misalignment between them and the already laid rails. This requires manual adjustment and alignment, which is not only time-consuming and labor-intensive, but also detrimental to the subsequent fixed installation of the rails.

[0005] Therefore, in order to solve the problems existing in the process of hoisting and lowering railway rails by railway rail laying hoisting equipment, the present invention provides a railway rail laying hoisting equipment. Summary of the Invention

[0006] This invention provides a railway track laying hoisting device, which includes: an installation frame, a clamping mechanism, and an alignment mechanism. The installation frame is connected to a crane, and the lower end of the installation frame is provided with the clamping mechanism and the alignment mechanism.

[0007] The lower end of the mounting frame is symmetrically equipped with electric hoists. The first wire rope on the electric hoist hangs down naturally and is divided into two at the lower end. A gantry frame is set at the lower end of the first wire rope, and the four corners of the top of the gantry frame are respectively connected to the corresponding second wire rope.

[0008] The gantry frame is equipped with a clamping mechanism, which includes two symmetrical mounting plates connected by a connecting rod. The upper ends of both mounting plates are connected to the horizontal section of the gantry frame by symmetrical steel wire ropes. Each mounting plate has an opening groove at its upper end, and a rod is installed inside the opening groove. The rod consists of two symmetrical double-threaded rods, and symmetrical grippers are threaded onto the outer ring surface of each double-threaded rod. The gripping end of the grippers is T-shaped. The right end of the rod is rotatably connected to the mounting plate and passes through the mounting plate. The left end of the rod rotatably passes through the left end of the mounting plate and is connected to a rotating wheel. The two rotating wheels are connected by a belt drive. The left end of the front rod passes through the rotating wheel and is connected to the output shaft of the motor. The motor is mounted on the left end of the mounting plate via an L-shaped bracket.

[0009] The alignment mechanism includes two symmetrical adjustment plates. The two adjustment plates are connected to the inner walls of the vertical sections on the left and right sides of the gantry frame by evenly arranged adjustment spring telescopic rods. L-shaped alignment rods are installed on the side of the rear end of the two adjustment plates that are close to each other. The shape of the vertical section of the L-shaped alignment rod is the same as the shape of the gripper end. The left end of the motor and the rear rod is in contact with the side of the left adjustment plate, and the right adjustment plate is in contact with the right end of the rod. A second electric push rod is installed in the middle of the lower end of the horizontal section of the gantry frame. A horizontal pressure plate is installed at the lower end of the second electric push rod.

[0010] In one embodiment, the front end of the mounting plate is provided with symmetrical U-shaped plates, and the interior of the U-shaped plates is provided with symmetrical arc-shaped blocks. The inner walls of the left and right vertical sections of the U-shaped plates are respectively connected to the arc-shaped blocks with telescopic springs. The two U-shaped plates are installed at the lower end of the same connecting plate. An electric slider is installed at the upper end of the connecting plate. The electric slider is installed on a guide rail. A first electric push rod is installed at each of the left and right ends of the guide rail. The first electric push rod is installed at the lower end of the horizontal section of the gantry frame through a fixing plate.

[0011] In one embodiment, the connecting rod is a threaded telescopic rod, and the upper end of the horizontal section of the gantry frame is provided with symmetrical sliding grooves. The upper end of the steel wire rope three located on the front side is respectively equipped with sliding blocks that are slidably connected to the sliding grooves. The upper end of the sliding blocks is fixedly connected to the horizontal section of the gantry frame by bolt No. 1.

[0012] In one embodiment, balance plates are symmetrically installed on the left and right sides of the gantry frame, and a counterweight is provided at the lower end of the balance plate. The balance plate and the counterweight are connected by a four-phase steel wire rope.

[0013] In one embodiment, a sleeve is provided below each of the two electric hoists and is fitted onto the first wire rope. An L-shaped plate is connected between the sleeve and the mounting frame, and the inner diameter of the sleeve is larger than the outer diameter of the first wire rope.

[0014] In one embodiment, the two jaws on the same bidirectional threaded rod are each fixedly connected to an elastic rubber plate at their closest ends by a No. 2 bolt.

[0015] In one embodiment, a scale plate symmetrically positioned between two threaded telescopic rods is mounted on the upper end of the front mounting plate.

[0016] In summary, the present invention has at least one of the following beneficial effects:

[0017] 1. This invention provides a railway track hoisting device that uses a clamping mechanism to hoist the rails, achieving automatic release of the rails from the hoisting fixation, eliminating the need for manual operation, and improving work efficiency. The synchronous movement of two pairs of jaws located on the same set of rods enables simultaneous clamping of two rails. Compared with the traditional method of clamping and installing a single rail at a time, this saves working time, reduces the repetition rate of operation steps, and improves the hoisting efficiency of the rails. The clamping ends of the jaws, which are matched to the shape of the rails, increase the stability during the clamping process, achieving multi-directional limiting and fixing of the rails in one step, effectively improving the hoisting stability of the rails.

[0018] 2. This invention provides a railway track laying hoisting device that uses two adjusting plates to guide and limit the downward movement of the clamping mechanism, enabling the clamping mechanism to adaptively adjust its position. This eliminates the need for manual alignment after the track is hoisted and lowered, thus improving the efficiency of track laying.

[0019] 3. This invention provides a railway track laying hoisting device, which uses an electric slider to drive the U-shaped plate and the arc block to make fine adjustments to the entire track in the left and right directions, so that the track is always in a horizontal alignment state. This avoids the need for subsequent manual adjustments due to errors in the installation position, which would increase installation time, be time-consuming and labor-intensive, and introduce a certain degree of human error.

[0033] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0034] Please see Figure 1 and Figure 6 A railway track laying hoisting device includes: an installation frame 1, a clamping mechanism 2 and an alignment mechanism 3. The installation frame 1 is connected to a crane, and the lower end of the installation frame 1 is provided with the clamping mechanism 2 and the alignment mechanism 3.

[0035] Please see Figure 1 Electric hoists 11 are symmetrically installed on the lower end of the mounting frame 1. The steel wire rope 12 on the electric hoist 11 hangs down naturally and is divided into two at the lower end. A gantry frame 13 is set at the lower end of the steel wire rope 12. The four corners of the top of the gantry frame 13 are respectively connected to the corresponding steel wire rope 14.

[0036] Please see Figure 1 , Figure 3 , Figure 7 , Figure 8 and Figure 10 The gantry frame 13 is internally equipped with a clamping mechanism 2, which includes two symmetrical mounting plates 21 connected by a connecting rod. The upper ends of the two mounting plates 21 are connected to the horizontal section of the gantry frame 13 by symmetrical steel wire ropes 22. The upper ends of the two mounting plates 21 are provided with opening grooves 23, and rods are provided inside the opening grooves 23. The rods are composed of two symmetrical bidirectional threaded rods 24. The outer ring surface of the bidirectional threaded rods 24 is threaded with symmetrical jaws 25. The clamping end of the jaws 25 is T-shaped. The right end of the rod is rotatably connected to the mounting plate 21 and passes through the mounting plate 21. The left end of the rod rotatably passes through the left end of the mounting plate 21 and is connected to a rotating wheel 26. The two rotating wheels 26 are connected by a belt 27. The left end of the front rod passes through the rotating wheel 26 and is connected to the output shaft of the motor 28. The motor 28 is mounted on the left end of the mounting plate 21 by an L-shaped support.

[0037] During the hoisting of rail 4, the crane moves the mounting frame 1 towards the rail 4. Simultaneously, the electric hoist 11, via wire rope 12, moves the clamping mechanism 2 and the alignment mechanism 3 towards rail 4. When the clamping mechanism 2 is above rail 4, the electric hoist 11 lowers it by using wire rope 12. When the jaws 25 on the same bidirectional threaded rod 24 are positioned on both sides of the same rail 4, the motor 28 and belt 27 work together to rotate the two sets of rods synchronously in the same direction, causing the jaws 25 on the same bidirectional threaded rod 24 to move towards each other. The T-shaped clamping ends of the jaws 25 engage with the T-shaped grooves on the left and right sides of rail 4 to clamp rail 4. Then, the clamping mechanism 2 and rail 4 are moved together to the installation position for subsequent installation. After the rail 4 is hoisted to the installation position and lowered, the motor 28 drives the two sets of rods to rotate in opposite directions, causing the grippers 25 to separate from the rail 4. Then, the electric hoist 11 drives the wire rope 12 to move the clamping mechanism 2 away from the rail 4, realizing the automatic release of the hoisting fixation of the rail 4. No manual operation is required, and the work efficiency is improved. The synchronous movement of the two pairs of grippers 25 located on the same set of rods realizes the synchronous clamping of the two rails 4. Compared with the traditional single clamping and installation of a single rail 4, it saves working time, reduces the repetition rate of operation steps, and improves the hoisting efficiency of the rail 4. The clamping end of the gripper 25, which matches the shape of the rail 4, increases the stability during the clamping process, realizing multi-directional limiting fixation of the rail 4 in one step, effectively improving the hoisting stability of the rail 4.

[0038] Please see Figure 1 , Figure 5 , Figure 6 and Figure 7 The alignment mechanism 3 includes two symmetrical adjustment plates 31. The two adjustment plates 31 are connected to the inner walls of the vertical sections on the left and right sides of the gantry frame 13 by evenly arranged adjustment spring telescopic rods 32. L-shaped alignment rods 33 are installed on the side of the rear ends of the two adjustment plates 31 that are close to each other. The shape of the vertical section of the L-shaped alignment rod 33 is the same as the shape of the clamping end of the gripper 25. The left end of the motor 28 and the rear rod are in contact with the side of the left adjustment plate 31, and the right adjustment plate 31 is in contact with the right end of the rod. A second electric push rod 35 is installed in the middle of the lower end of the horizontal section of the gantry frame 13. A horizontal pressure plate 36 is installed at the lower end of the second electric push rod 35.

[0039] Before the clamping mechanism 2 lowers the two rails 4 after they have been hoisted to their installation positions, the L-shaped alignment rods 33 are manually moved away from each other. This causes the adjusting spring telescopic rod 32 to retract under pressure. Once the vertical section of the L-shaped alignment rod 33 aligns with the side end of the laid rail 4, the L-shaped alignment rod 33 is released. Under the action of the adjusting spring telescopic rod 32, the vertical section of the L-shaped alignment rod 33 contacts the side end of the laid rail 4. At this point, the distance between the two adjusting plates 31 is fixed. Then, the clamping mechanism 2... As the movable rail 4 descends, when the motor 28 and the left end of the rear rod both contact the side of the left adjustment plate 31, and the right adjustment plate 31 contacts the right end of the rod, the rail 4 to be installed reaches the installation position and aligns with the already laid rail 4. The two adjustment plates 31 guide and limit the downward movement of the clamping mechanism 2, allowing the clamping mechanism 2 to adaptively adjust its position. This eliminates the need for manual alignment after the rail 4 is hoisted and lowered, improving the laying efficiency of the rail 4. After alignment, the second electric push rod 35 presses down the horizontal pressure plate 36, applying downward pressure to the rail 4, initially stabilizing it on the sleeper. This ensures that during the separation of the clamping mechanism 2 and the alignment mechanism 3 from the rail 4, the rail 4 remains horizontally and stably positioned on the sleeper, preventing it from shifting. This facilitates subsequent fixing of the rail 4 by workers, further improving laying efficiency.

[0040] Please see Figure 1 , Figure 2 , Figure 3 and Figure 9 The front end of the mounting plate 21 is provided with symmetrical U-shaped plates 29. The interior of the U-shaped plates 29 is provided with symmetrical arc-shaped blocks 291. The inner walls of the left and right vertical sections of the U-shaped plates 29 and the arc-shaped blocks 291 are respectively connected by telescopic springs 292. The two U-shaped plates 29 are installed at the lower end of the same connecting plate 293. The upper end of the connecting plate 293 is equipped with an electric slider 294. The electric slider 294 is installed on the guide rail 295. The left and right ends of the guide rail 295 are respectively equipped with electric push rods 212. The electric push rods 212 are installed at the lower end of the horizontal section of the gantry frame 13 through a fixing plate.

[0041] When the gripper 25 clamps the rail 4, the U-shaped plate 29 located at the front end of the rail 4 clamps the front ends of the two rails 4 simultaneously through the cooperation of the telescopic spring 292 and the arc-shaped block 291. After the alignment between the rail 4 to be installed and the already laid rail 4 is completed, the other end of the rail 4 to be installed may be tilted due to the lack of a reference point. At this time, the electric slider 294 drives the U-shaped plate 29 and the arc-shaped block 291 to make a slight adjustment to the rail 4 in the left and right directions, so that... The rail 4 is always in a horizontally aligned state. After the rail 4 is finely adjusted, the No. 1 electric push rod 212 causes the U-shaped plate 29 to move horizontally and separate from the rail 4, and then the clamp 25 releases its grip on the rail 4. Subsequently, the U-shaped plate 29 and the clamping mechanism 2 move upward synchronously and completely separate from the rail 4, which prepares for the subsequent installation of the rail 4. This avoids the need for subsequent manual adjustment due to errors in the installation position, which would increase installation time, be time-consuming and labor-intensive, and introduce a certain degree of human error.

[0042] Please see Figure 4 , Figure 5 , Figure 6 , Figure 8 and Figure 9 The connecting rod is a threaded telescopic rod 211. The upper end of the horizontal section of the gantry frame 13 is provided with a symmetrical sliding groove 213. The upper end of the steel wire rope 22 located on the front side is respectively equipped with a sliding block that is slidably connected to the sliding groove 213. The upper end of the sliding block is fixedly connected to the horizontal section of the gantry frame 13 by a bolt No. 1.

[0043] When the length of rail 4 changes, the first bolt at the top of the sliding block is removed, and the front mounting plate 21 is moved forward by rotating the threaded telescopic rod 211. At this time, the wire rope 22 slides forward in the sliding groove 213 synchronously with the sliding block. After adjusting to a suitable distance, the sliding block is fixed to the horizontal section of the gantry frame 13 again by the first bolt. By adjusting the distance between the two mounting plates 21, the clamping and fixing range of rail 4 is expanded, which improves the hoisting stability of rail 4 and ensures that rail 4 is subjected to uniform and balanced force. When the distance between the two mounting plates 21 changes, the rotating wheels 26 of the front and rear rods can still maintain the transmission connection by replacing the belts 27 of different sizes.

[0044] Please see Figure 1 , Figure 3 and Figure 5 The gantry frame 13 is symmetrically equipped with balance plates 131 on the left and right sides. A counterweight 132 is provided at the lower end of the balance plate 131. The balance plate 131 and the counterweight 132 are connected by a steel wire rope 133.

[0045] The counterweight 132 is used to make the gantry frame 13, the clamping mechanism 2 and the alignment mechanism 3 reach overall balance, ensuring that the clamping mechanism 2 is in a vertical and stable balanced state before clamping and fixing the rail 4, which improves the stability of the subsequent hoisting of the rail 4, and also facilitates the stable release of the clamping mechanism 2 from the rail 4.

[0046] Please see Figure 1 and Figure 3 Each of the two electric hoists 11 is provided with a sleeve 111 fitted on the wire rope 12. An L-shaped plate is connected between the sleeve 111 and the mounting frame 1. The inner diameter of the sleeve 111 is larger than the outer diameter of the wire rope 12.

[0047] The sleeve 111 is used to guide and limit the wire rope 12, restricting the range of motion of the wire rope 12 within the sleeve 111, so as to avoid the wire rope 12 from swaying significantly during movement and affecting the hoisting of the rail 4.

[0048] Please see Figure 7 , Figure 8 and Figure 10 The two jaws 25 on the same bidirectional threaded rod 24 are each fixedly connected to an elastic rubber plate 251 at their closest ends by a No. 2 bolt.

[0049] When the jaw 25 contacts the T-shaped groove of the rail 4, the elastic rubber plate 251 increases the friction between the jaw 25 and the rail 4, thereby improving the clamping and fixing firmness of the jaw 25 on the rail 4. In order to prevent the elastic rubber plate 251 from wearing out due to long-term contact and friction after continuous use, it is designed to be detachable. The elastic rubber plate 251 can be removed and replaced in time by bolt No. 2.

[0050] Please see Figure 6 , Figure 7 and Figure 8 The upper end of the mounting plate 21 on the front side is equipped with a scale plate 215 that is symmetrical from left to right and located between the two threaded telescopic rods 211.

[0051] The scale plate 215 can be used to precisely adjust the distance between the front and rear mounting plates 21 according to the length of the rail 4, so as to ensure that rails 4 of different lengths can be clamped and hoisted in a uniform and balanced state.

[0052] The working principle of this invention is as follows: When hoisting the rail 4, the crane moves the mounting frame 1 towards the rail 4. Simultaneously, the electric hoist 11, via the wire rope 12, drives the clamping mechanism 2 and the alignment mechanism 3 towards the rail 4. When the clamping mechanism 2 is above the rail 4, the electric hoist 11 lowers it by using the wire rope 12. When the jaws 25 on the same bidirectional threaded rod 24 are positioned on opposite sides of the same rail 4, the motor 28 and belt 27 work together to rotate the two sets of rods synchronously in the same direction, causing the jaws 25 on the same bidirectional threaded rod 24 to move towards each other. The T-shaped clamping end engages with the T-shaped grooves on the left and right sides of rail 4 to clamp rail 4. While the gripper 25 is clamping rail 4, the U-shaped plate 29 at the front end of rail 4, through the cooperation of the telescopic spring 292 and the arc-shaped block 291, simultaneously clamps the front ends of both rails 4. The electric slider 294 drives the U-shaped plate 29 and the arc-shaped block 291 to make minor adjustments to rail 4 in the left and right directions, ensuring that rail 4 remains horizontally aligned. After the minor adjustment of rail 4 is completed, the first electric push rod 212 causes the U-shaped plate 29 to move horizontally, separating it from rail 4, and then the gripper is released. The clamping mechanism 2 and the rail 4 are moved together to the installation position of the rail 4. Before the clamping mechanism 2 drives the rail 4 to fall, the L-shaped alignment rods 33 are manually moved away from each other, and the adjusting spring telescopic rod 32 is compressed and retracted. After the vertical section of the L-shaped alignment rod 33 is aligned with the side end of the already laid rail 4, the L-shaped alignment rod 33 is released. Under the action of the adjusting spring telescopic rod 32, the vertical section of the L-shaped alignment rod 33 abuts against the side end of the already laid rail 4. At this time, the distance between the two adjusting plates 31 is fixed. Then the clamping mechanism 2 drives the rail 4 to fall. When the motor 28 and the rear rods... When the left end of the rod abuts against the side of the left adjustment plate 31 and the right adjustment plate 31 abuts against the right end of the rod, the rail 4 to be installed reaches the installation position and aligns with the already laid rail 4. After alignment, the horizontal pressure plate 36 is pressed down by the second electric push rod 35. The horizontal pressure plate 36 gives the rail 4 a downward pressure, so that the rail 4 is initially fixed to the sleeper. Finally, the motor 28 drives the front and rear rods to rotate in opposite directions, so that the clamp 25 separates from the rail 4. Then, the electric hoist 11 drives the wire rope 12 to move the clamping mechanism 2 away from the rail 4, so as to automatically release the hoisting and fixing of the rail 4.
