Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of track transportation auxiliary tool, especially relates to a carriage derailment reset device. BACKGROUND

[0002] At present, track transportation is a common transportation mode, such as the transportation and transfer of a large number of raw materials or equipment in the construction site. Due to the quality problem of steel rail laying or long-term use and maintenance, the deformation of the steel rail will be caused. Or uneven loading of goods will cause the center of gravity of the carriage to deviate, which is easy to cause the derailment of the carriage during operation, not only affects the normal construction progress, but also brings great safety hazards.

[0003] At present, when the carriage derails in the construction site, the vehicle is usually lifted by the jack, and then the carriage is pushed transversely to reset the derailed carriage. In this process, the operating personnel are always around the derailed carriage, so that personnel safety accidents are easy to occur. In addition, this carriage resetting mode also consumes a lot of manpower and time, and the resetting efficiency is low. In addition, since the carriage needs to move transversely during resetting, the jack is easy to fall due to instability.

[0004] The patent with publication number CN209320957U discloses a train rail resetting device, which comprises a base and a lifting mechanism located on the base, the lifting mechanism comprises a base, a supporting plate, a lifting column and a lifting cylinder; the lifting of the lifting column is realized through the extension and retraction of the lifting cylinder, so that the up and down displacement of the train is realized; a translation mechanism is further arranged on the base to realize the left and right translation of the lifting mechanism in the base. Since the jacking and horizontal transverse movement of the train are realized by the oil cylinder, a hydraulic station and a corresponding power source need to be equipped, such as the carriage without power source, which cannot be used, so that the supporting conditions on site are required to be higher.

[0024] Example 1

[0025] like Figures 1 to 4 As shown, a derailment reset device for a train carriage includes a gantry frame 6 spanning two steel rails 9, two U-shaped support seats 7 fixedly connected to the bottom ends of the gantry frame 6, and track wheels 11 rotatably connected within each support seat 7. The track wheels 11 have an H-shaped cross-section and can roll along the steel rails 9. Clamping mechanisms 8 for clamping the steel rails 9 are provided on both sides of each support seat 7. A lug is welded to the top of the gantry frame 6 at the middle position, and a lifting mechanism 13 is provided on the lug. The lifting mechanism 13 has a flexible cable. The lifting mechanism 13 is a hand-operated hoist hanging on the lug, and the cable is the chain of the hand-operated hoist, with a hook at the end of the chain for hooking onto the train carriage 28.

[0026] Each support 7 has a rectangular blocking plate 2 welded to both ends, with a gap between the lower edge of the blocking plate 2 and the rail 9. Each clamping mechanism 8 includes a rectangular mounting plate 23 connected to the outside of the corresponding blocking plate 2, a vertical sliding sleeve 19 fixedly connected to the outside of the mounting plate 23, a vertically penetrating pull rod 18 slidably connected within the sliding sleeve 19, and an eccentric wheel 20 rotatably connected to the top of the pull rod 18. The part of the eccentric wheel 20 connected to the pull rod 18 is offset from the center of the eccentric wheel 20, and the outer circle of the eccentric wheel 20 abuts against the top of the sliding sleeve 19. A handle 24 is fixedly connected to the outer circle of the eccentric wheel 20. When the handle 24 is turned, the eccentric wheel drives the pull rod 18 to move up and down. To make the pull rod 18 move more smoothly downward, a return spring can be fitted onto the pull rod 18, and a cylindrical pin inserted into the pull rod 18 can be set below the return spring, clamping the return spring between the cylindrical pin and the sliding sleeve 19, thereby applying a downward pulling force to the pull rod 18. Two limiting pins 25 are also fixedly connected to the outside of the mounting plate 23 to limit the swing range of the handle 24.

[0027] The lower end of the pull rod 18 has two connecting rods 17 arranged in a V-shape. Each connecting rod 17 has an L-shaped hook 14 at its lower end. The two hooks 14 are arranged in a V-shape on both sides of the rail 9, with the hook tips facing the middle of the rail 9. The distance between the hook tips of the two hooks 14 is greater than the width of the top of the rail 9. The upper ends of the two connecting rods 17 are rotatably connected to the lower end of the pull rod 18, and the lower ends of the two connecting rods 17 are rotatably connected to the upper ends of the corresponding hooks 14. The upper part of the hook 14 has a first strip-shaped hole 15 along its length. A sliding pin 16 is fixedly connected to the mounting plate 23, passing through the first strip-shaped hole 15. The outer diameter of the sliding pin 16 is greater than the width of the first strip-shaped hole 15. The middle parts of the hook 14 and the sliding pin 16 are both rotatably and slidably engaged.

[0028] Combination Figure 5 As shown, the working process of this utility model is as follows:

[0029] 1. Place this utility model on the rail 9 so that the top of the rail 9 enters the groove of the track wheel 11, at which time the two hooks 14 are located on both sides of the rail 9.

[0030] 2. Drag the gantry 6 along the rail 9 until it is close to the rear of the carriage 28. Then, pull the handle 24 so that it rests against the left-hand limit pin 25. The pull rod 18 pulls the connecting rod 17 and hook 14 upwards in sequence. As the hook 14 moves along the sliding pin 16, it rotates along the sliding pin 16, thus gripping the top of the rail 9 and firmly locking the support seat 7 onto the rail 9. At this time, the rotational connection between the pull rod 18 and the eccentric wheel 20 is higher than the center of the eccentric wheel 20 and is located in the same vertical plane as the center of the eccentric wheel 20, thus causing the eccentric wheel 20 to reach its dead point and locking the position of the pull rod 18.

[0031] 3. Attach the hook of the hand-operated hoist to the rear of carriage 28. Use the hoist to lift the rear of carriage 28. When the wheels of carriage 28 are higher than rail 9, push the rear of carriage 28 laterally so that the wheels are above rail 9. Slowly lower carriage 28 using the hoist to place the wheels on rail 9, ultimately achieving wheel repositioning. If the front wheels of carriage 28 also derail, the same method can be used to reposition them.

[0032] After the carriage 28 is lifted by the hand chain hoist, it is easily pushed laterally because the chain of the hand chain hoist is flexible. In addition, since the hand chain hoist is located in the middle of the gantry 6, after the wheels of the carriage 28 derail, the connection position of the hook at the end of the chain and the carriage 28 will deviate from the symmetrical plane of the two rails 9. The symmetrical plane of the two rails 9 passes through the middle position of the gantry 6, and the connection position of the hand chain hoist and the gantry 6 is located on this symmetrical plane. Therefore, while the hand chain hoist pulls the carriage 28 upward, it will also pull the carriage 28 laterally, making it easier and faster to reset the carriage 28.

[0033] Before the hand-operated hoist pulls the carriage 28, the gantry 6 and the support 7 are locked to the rail 9 by the clamping mechanism, thus preventing the gantry 6 from tipping over due to excessive tension when the hand-operated hoist pulls the carriage 28.

[0034] Example 2

[0035] like Figure 3 As shown, the difference between this embodiment and Embodiment 1 is that:

[0036] The mounting plate 23 has vertical second strip-shaped holes 21 near each of its four corners. The lower end of each second strip-shaped hole 21 has a through hole with a diameter greater than its width that communicates with it. A fixing pin 22 is fixedly connected to each second strip-shaped hole 21 on the blocking plate 2. The head diameter of the fixing pin 22 is smaller than the diameter of the through hole but larger than the width of the second strip-shaped hole 21. The rod diameter of the fixing pin 22 is smaller than the width of the second strip-shaped hole 21, and the rod is located at the top of the second strip-shaped hole 21.

[0037] Pull the handle 24 to release the two hooks 14 from the rail 9, then push the mounting plate 23 upwards to align the outer end of the fixing pin 22 with the through hole on the mounting plate 23. Then, remove the mounting plate 23 outwards to remove the clamping mechanism 8. In use, first place the track wheel 11 on the rail 9, then install the mounting plate 23 onto the blocking plate 2. Because the lower part of the hook 14 is lower than the bottom of the track wheel 11, this invention allows the clamping mechanism 8 to be removed when not in use to prevent the hook 14 from deforming due to impact, thus affecting normal use.

[0038] Example 3

[0039] like Figure 1 and Figure 3 As shown, the difference between this embodiment and Embodiment 2 is that:

[0040] The support base 7 is slidably connected to the U-shaped wheel seat 10, and the wheel seat 10 is vertically elastically connected to the support base 7. The track wheel 11 is rotatably connected to the wheel seat 10.

[0041] The bottom surface of the blocking plate 2 is fixedly connected with a rectangular brake block 1, and the top surface of the wheel seat 10 is fixedly connected with a vertical slide rod 3. The slide rod 3 is slidably connected to the support seat 7. A spring 4 is provided between the wheel seat 10 and the support seat 7 and is sleeved on the slide rod 3. A first nut 5 is provided on the outside of the support seat 7 and screwed on the top of the slide rod 3. Tightening the first nut 5 can adjust the distance between the brake block 1 and the rail 9.

[0042] When the eccentric wheel 20 pulls the lever 18 upward, the spring 4 is compressed, and the brake block 1 presses against the top surface of the rail 9, thereby preventing the support seat 7 from moving.

[0043] The track wheel 11 is rotatably connected to the rotating shaft 12 along its axis, and a bearing is provided between the rotating shaft 12 and the track wheel 11. On both sides of the wheel seat 10, at positions corresponding to the rotating shaft 12, there are vertical first notches 26 for the rotating shaft 12 to pass through, and the first notches 26 communicate with the bottom surface of the wheel seat 10. A nut is screwed onto the wheel seat 10 to lock the rotating shaft 12 onto the wheel seat 10. On both sides of the support base 7, at positions corresponding to the first notches 26, there are vertical second notches 27, and the second notches 27 communicate with the bottom surface of the support base 7. The width of the second notches 27 is larger than the size of the socket on the socket wrench used to tighten the nut.

[0044] When installing the track wheel 11, first pass the rotating shaft 12 through the track wheel 11, then install the bearing, tighten the nut at the upper end, and then install the rotating shaft 12 onto the wheel seat 10 through the first notch 26 and the second notch 27. Tighten the nut with a socket wrench to install the track wheel 11 in place.

[0045] After setting the first notch 26 and the second notch 27, the disassembly and assembly of the track wheel 11 can be made more convenient, and the disassembly and assembly of the track wheel 11 can be achieved without removing the wheel seat 10.

[0046] The above-described embodiments are detailed and specific, illustrating preferred embodiments of the present utility model. They are only used to illustrate the technical ideas and features of the present utility model, with the aim of enabling those skilled in the art to understand the content of the present utility model and implement it accordingly. However, they are not limited to the present utility model, and the patent scope of the present utility model cannot be limited by this embodiment alone. That is, any equivalent changes or modifications made to the spirit disclosed in the present utility model, without departing from the structure of the present utility model, such as local improvements within the system and modifications or transformations between subsystems, are still within the patent scope of the present utility model.
