Description

Technical Field

[0001] The present application relates to the technical field of railway maintenance appliances, and particularly to a separable hydraulic rail straightener. Background Art

[0002] Rail is the most fundamental and important component of a railway track, and the condition of the rail affects the running safety of trains. During the production, transportation, and construction processes of rails, problems such as distortion and hard bend may occur. If the rails with problems are laid on the line, it will cause harm such as gauge over-tolerance and installation difficulties.

[0003] Currently, the problems existing in the above-mentioned rails are mainly repaired by using a track hydraulic rail straightener. The existing hydraulic rail straighteners are mainly divided into two categories.

[0004] The first category: an integral hydraulic rail straightener, that is, the body frame and the top block for straightening the rail are integrally arranged. Since different types of rails require different top blocks, the versatility of the integral hydraulic rail straightener is poor. At the same time, the weight of the straightener corresponding to heavy rails is also large. It is difficult for operators to install and operate the machine, increasing the labor intensity.

[0005] The second category: a separable hydraulic rail straightener, that is, the underframe assembly and the locking hook assembly are separated. However, the assembly position of the locking hook and the underframe of the existing separable hydraulic rail straightener is fixed and non-adjustable, and the range of the straightening force is small, and its practicability for heavy-haul railways is poor. During operation, its acting force contacts the side surface of the rail head, and only local deformation of the rail head can be achieved. As the train passes, the local deformation will disappear, and new damage will also be caused to the working surface of the rail head. Summary of the Utility Model

[0006] In view of this, the purpose of the present application is to provide a separable hydraulic rail straightener to solve the problems of large weight, small applicable range, and damage to the rail head of the existing hydraulic rail straighteners.

Rather, the examples described herein are provided only to illustrate some of the many possible ways of implementing the methods, devices, and / or systems described herein that will be apparent after understanding the disclosure of the present application.

[0030] Throughout the specification, when an element (such as, a layer, a region, or a substrate) is described as being "on" another element, "connected to" another element, "coupled to" another element, "above" another element, or "covering" another element, it can be directly "on" another element, "connected to" another element, "coupled to" another element, "above" another element, or "covering" another element, or there can be one or more other elements intervening therebetween. In contrast, when an element is described as being "directly on" another element, "directly connected to" another element, "directly coupled to" another element, "directly above" another element, or "directly covering" another element, there can be no other elements intervening therebetween.

[0031] As used herein, the term "and / or" includes any one of the listed related items and any combination of any two or more of them.

[0032] Although terms such as "first", "second", and "third" may be used herein to describe various components, elements, regions, layers, or parts, these components, elements, regions, layers, or parts are not limited by these terms.

[0037] As Figures 1 to 7 shown, according to a first aspect of the present utility model, a separable hydraulic rail straightener is provided, which includes a body frame main body 1, an oil cylinder assembly 2, a locking hook assembly 3, and a clearance adjustment assembly 4.

[0038] In the following description, reference will be made to Figures 1 to 7 specifically describe the specific structures of the above components of the separable hydraulic rail straightener and the connection relationships of the above components.

[0039] As Figures 1 to 7 shown, in an embodiment, a first top block 10 may be installed at the first end (which may be the right end as Figure 2 shown) of the body frame main body 1. The first top block 10 is used to abut against the web 72 of the rail 7. The oil cylinder assembly 2 may be disposed at the second end (which may be as Figure 2The left end shown). The oil cylinder assembly 2 may be installed with a second top block 20. The second top block 20 is used to abut against the web 72 of the rail 7, and the oil cylinder assembly 2 can drive the second top block 20 to apply pressure to the web 72 of the rail 7. The locking hook assembly 3 can be installed on the main body 1 of the fuselage frame. The separable design of the locking hook assembly 3 and the main body 1 of the fuselage frame can prevent the overall weight of the separable hydraulic rail straightener from being too large, making it easy for the operator to disassemble and transport. The locking hook assembly 3 may be provided with a third top block 30. When the locking hook assembly 3 is installed on the main body 1 of the fuselage frame, the main body 1 of the fuselage frame and the rail 7 are clamped inside the locking hook assembly 3. The third top block 30 abuts against the lower jaw 710 of the rail head and the upper surface 730 of the rail bottom at the bent part of the rail 7 to prevent local deformation of the rail head 71. The third top block 30, the first top block 10, and the second top block 20 may be located on both sides of the rail 7 respectively, thus forming a lever structure. The first top block 10 may serve as a fulcrum. When the third top block 30 presses against the bent part of the rail 7, applying pressure to the web 72 of the rail 7 by the second top block 20 can enable the third top block 30 to apply a rail straightening force to the bent part of the rail 7. The gap adjustment assembly 4 can be movably installed on the main body 1 of the fuselage frame. When the locking hook assembly 3 is installed on the main body 1 of the fuselage frame, the gap adjustment assembly 4 is clamped between the locking hook assembly 3 and the main body 1 of the fuselage frame to fill the gap between the locking hook assembly 3 and the main body 1 of the fuselage frame, enabling the locking hook assembly 3 to be flexibly installed at multiple parts of the main body 1 of the fuselage frame to increase the range within which the rail straightening force can be applied.

[0040] Preferably, as Figures 1 to 3 shown, in the embodiment, the main body 1 of the fuselage frame can be approximately strip-shaped. When in use, the main body 1 of the fuselage frame can be arranged along the length direction of the rail 7. The main body 1 of the fuselage frame is arranged on one side of the rail 7. The locking hook assembly 3 is separately arranged from the main body 1 of the fuselage frame. During transportation, the operator can transport the locking hook assembly 3 and the main body 1 of the fuselage frame separately and then install them together when in use. The locking hook assembly 3 may include a locking hook main body 31. Preferably, the locking hook main body 31 can be a U-shaped plate member. The third top block 30 can be arranged inside the locking hook main body 31, that is, inside the opening of the locking hook main body 31. The third top block 30 can be bolted to the locking hook main body 31. When the locking hook assembly 3 is installed on the main body 1 of the fuselage frame, the third top block 30 and the main body 1 of the fuselage frame are located on opposite sides of the rail 7 respectively.

[0041] In addition, preferably, as Figure 1 and Figure 2 and Figure 7As shown, in the embodiment, the first top block 10, the second top block 20, and the third top block 30 can be plate-shaped components. The sides of the first top block 10 and the second top block 20 are in contact with the web 72. The side of the third top block 30 is in contact with the lower jaw 710 of the rail head and the upper surface 730 of the rail base of the rail 7. With such a setting, it can not only protect the rail head 71 from damage, but also straighten the bent part of the rail 7 and prevent local deformation of the rail head 71.

[0042] Preferably, as Figures 1 to 3 shown, in the embodiment, the gap adjustment assembly 4 and the first top block 10 and the second top block 20 can be respectively arranged on both sides of the fuselage frame main body 1. The gap adjustment assembly 4 can include an adjustment assembly main body 40, a fixing bolt 41, and a locking nut 42. Among them, the bottom side of the adjustment assembly main body 40 (i.e., the side facing the side part of the fuselage frame main body 1 as shown in Figure 2 can be formed as an open side. The bottom side of the adjustment assembly main body 40 can be clamped on the fuselage frame main body 1, that is, the plate part of the fuselage frame main body 1 is inserted into the open side of the adjustment assembly main body 40. The adjustment assembly main body 40 can move along the length direction of the fuselage frame main body 1. On the top side of the adjustment assembly main body 40 (i.e., the side facing the hook assembly 3 as shown in Figure 1 ), an inclined surface 400 can be provided, and the inclined surface 400 extends in the length direction of the fuselage frame main body 1. By moving the adjustment assembly main body 40, the gap between the hook assembly 3 and the fuselage frame main body 1 can be adjusted, so that the hook assembly 3 can remain stable during operation. In addition, the adjustment assembly main body 40 can move following the installation position of the hook assembly 3, so that the range of the straightening force of the rail can be adjusted. The fixing bolt 41 can pass through the plate part of the fuselage frame main body 1. A strip-shaped groove 401 extending along the length direction of the fuselage frame main body 1 can be formed on the adjustment assembly main body 40. The fixing bolt 41 also passes through the strip-shaped groove 401. Preferably, the number of the fixing bolts 41 can be multiple. A plurality of the locking nuts 42 can be installed on the plurality of the fixing bolts 41. The plurality of the locking nuts 42 can be respectively arranged on both sides of the adjustment assembly main body 40, and then the adjustment assembly main body 40 is locked and fixed to the fuselage frame main body 1.

[0043] More preferably, as Figure 1 and Figure 2 shown, in the embodiment, the middle part of the fuselage frame main body 1 can be formed as a plate part, and the plate part is formed with a straight section 11. The gap adjustment assembly 4 can be installed on the straight section 11. The adjustment assembly main body 40 can move on the straight section 11 to adapt to the installation position of the hook assembly 3.

[0044] Preferably, as Figures 1 to 5As shown, in the embodiment, the oil cylinder assembly 2 may include an oil tank 21, a cylinder block 22, a piston cylinder 23, a piston rod 231, a plunger pump core assembly 24, and a swing rod assembly. Among them, the oil tank 21 may be formed in a cylindrical shape, and pressure oil is stored inside the oil tank 21. The cylinder block 22 may be connected to the end of the oil tank 21. The piston cylinder 23 is connected to the cylinder block 22. The piston cylinder 23 is fixedly installed at the second end of the fuselage frame main body 1. The piston rod 231 is disposed inside the piston cylinder 23. The piston rod 231 may be connected to the third top block 30 to drive the third top block 30 to move. The plunger pump core assembly 24 may be installed outside the cylinder block 22. When the plunger pump core assembly 24 moves in the first direction, the pressure oil in the oil tank 21 can enter the cylinder block 22, and the first direction may be the upward direction as shown in Figure 4 , that is, lifting the plunger pump core assembly 24. When the plunger pump core assembly 24 moves in the second direction, the pressure oil in the cylinder block 22 can enter the piston cylinder 23, and the second direction may be the downward direction as shown in Figure 4 , that is, pressing down the plunger pump core assembly 24. After the pressure oil enters the piston cylinder 23, it can drive the piston rod 231 to extend, and then drive the third top block 30 to apply pressure to the rail 7. The swing rod assembly is swingably installed on the fuselage frame main body 1. The swing rod assembly may be connected to the plunger pump core assembly 24. During the swinging process of the swing rod assembly, it can drive the plunger pump core assembly 24 to move in the first direction or the second direction.

[0045] Specifically, as shown in Figures 2 to 5 , in the embodiment, a cylindrical sleeve portion 12 may be provided at the second end of the fuselage frame main body 1.

The swing rod assembly may include a connecting member 251, a pressure oil connecting sleeve 252, and a lever 253. Among them, the connecting member 251 may be a strip-shaped plate member. The first end of the connecting member 251 (which may be the lower end as shown in Figure 4 ) is pivotally connected to the sleeve portion 12. The end of the pressure oil connecting sleeve 252 may be pivotally connected to the second end of the connecting member 251 (which may be the upper end as shown in Figure 4 ). The middle of the pressure oil connecting sleeve 252 may be pivotally connected to the plunger pump core assembly 24. During the pivotal swinging process of the pressure oil connecting sleeve 252, the plunger pump core assembly 24 moves with the pressure oil connecting sleeve 252. The first end of the lever 253 may be provided with a handgrip portion 2530 to facilitate the operator's grasping. The second end of the lever 253 may be inserted into the pressure oil connecting sleeve 252, and the lever 253 may be threadedly connected to the pressure oil connecting sleeve 252.

The oil return valve 26, the spare oil return valve 27, and the overflow valve 28 may be installed on the cylinder block 22. During use, the lever 253 is inserted into the pressure oil connection sleeve 252. When the pressure oil connection sleeve 252 is lifted, the plunger pump core assembly 24 is driven to move upward, and the pressurized oil in the fuel tank 21 enters the cylinder block 22 through the filter and the oil suction valve. When the pressure oil connection sleeve 252 is pressed down, the plunger pump core assembly 24 is driven to move downward, and the pressurized oil then enters the piston cylinder 23 to push the piston rod 231 to work. After the work is completed, the oil return valve 26 is opened, and the pressurized oil in the piston cylinder 23 pushes open the steel ball and returns to the fuel tank 21, and the piston rod 231 is reset by the return spring.

[0047] In addition, preferably, as Figure 1 and Figure 2 shown, in the embodiment, a plurality of traveling components 6 for traveling along the rail 7 may be further provided on the main body 1 of the fuselage frame. Preferably, the traveling component 6 may include a traveling wheel and a bracket for installing the traveling wheel, and the bracket may be bolted to the main body 1 of the fuselage frame. The traveling component 6 may be installed on one side of the main body 1 of the fuselage frame where the gap adjustment component 4 is provided. Preferably, two traveling components 6 may be respectively provided at both ends in the length direction of the main body 1 of the fuselage frame. With such a setting, the split hydraulic straightening device can travel along the rail 7 to reduce the handling labor intensity of the operator.

[0048] More preferably, as Figure 1 and Figure 2 shown, in the embodiment, an inclined fixed connection sleeve 13 may be provided on the plate surface in the middle of the main body 1 of the fuselage frame. Specifically, the first end of the fixed connection sleeve 13 may be integrally formed with the main body 1 of the fuselage frame, and a circular opening may be formed at the second end of the fixed connection sleeve 13. The fixed connection sleeve 13 may be inclined from the first end to the second end in the direction close to the first end of the main body 1 of the fuselage frame. The second end of the lever 253 can be inserted into the second end of the fixed connection sleeve 13 to facilitate the operator to push the split hydraulic straightening device to travel along the rail 7.

[0049] In addition, preferably, the separable hydraulic straightening device for rails may further include a measuring assembly 5, and the measuring assembly may include a power supply box body 51, a power switch 52, a distance measuring assembly 53, a display screen 54, a threaded pipe 55 and a telescopic support leg frame 56. Among them, the power supply box body 51 is detachably mounted in the middle of the main body of the fuselage frame 1. Specifically, it can be bolted. The power switch 52 can be mounted on the power supply box body for turning on or off the power supply. The distance measuring assembly 53 can be connected to the power supply box body 51 through a wire 50, and the wire 50 can be inserted and connected to the power supply box body 51. Specifically, the distance measuring assembly 53 can be a distance measuring device such as a laser displacement sensor, an eddy current sensor or a rangefinder. A display screen 54 can be arranged on the power supply box body 51, and the display screen 54 can display the measured value of the distance measuring assembly 53. The threaded pipe 55 can be arranged at the bottom of the distance measuring assembly 53. Preferably, the distance measuring assembly 53 can be bolted to the top end of the threaded pipe 55. The telescopic support leg frame 56 can be mounted on the threaded pipe 55. The top end of the telescopic support leg frame 56 can be threadedly connected to the threaded pipe 55, and the bottom end of the telescopic support leg frame 56 can extend out of the bottom end of the threaded pipe 55 for supporting on the ground. The bottom end of the telescopic support leg frame 56 can be formed into a disc shape.

[0050] When the measuring assembly 5 is working, first record the straightening amount required for straightening the rail 7, and place the separable hydraulic straightening device for rails at the designated working position. After installation, align the distance measuring assembly 53 with the rail to be straightened, turn on the power switch 52, record the initial value (or zero) of the display screen 54, and then perform the hydraulic pressure application for straightening the rail. When the data difference (or the displayed data) on the display screen 54 is the same as the straightening amount required for straightening (within the allowable error range), the pressure application can be stopped and the pressure can be maintained for two minutes. The measuring assembly 5 can accurately control the straightening amount, greatly improving the straightening efficiency and accuracy.

[0051] During the use of the separable hydraulic rail straightener, first, the bent part of the rail 7 is detected to measure the straightening amount value. Then, the sleeper fasteners on both sides of the bent part of the rail 7 are loosened. The separable hydraulic rail straightener is placed on the opposite side of the direction where the rail 7 needs to be straightened, and a top block adapted to the rail shape is installed. Then, the third top block 30 of the hook assembly 3 is abutted against the part to be straightened, and the first top block 10 and the second top block 20 are abutted against the rail web 72. The gap adjustment assembly 4 is adjusted until the hook assembly 3 is fixed. The distance measuring assembly 53 of the measuring assembly 5 is placed in the direction where the rail 7 needs to be straightened and is collinear with the third top block 30. Subsequently, the oil return valve 26 and the spare oil return valve 27 are tightened, and then the lever 253 is inserted into the oil pressing connecting sleeve 252. The swing of the lever 253 can extend the piston rod 231. The lever 253 is swung multiple times until the required straightening amount is reached, and then the pressure is maintained for 2 minutes to achieve the purpose of straightening the rail 7. After the work is completed, the oil return valve 26 is loosened, and the piston rod 231 can automatically reset. The operator can remove the separable hydraulic rail straightener from the track to perform the next cycle of operation.
