Description

Technical Field

[0001] The invention belongs to the technical field of traveling vehicles, and in particular relates to a method for handling derailment of a traveling vehicle. Background Art

[0002] However, the cranes currently on the market are not convenient to fix when they are running, and they are prone to sliding, causing shaking when hoisting goods. In addition, since the goods hoisted by the crane are relatively heavy, it is easy to cause the lifting equipment to tilt, causing the crane to overturn and causing safety accidents. When the crane is hoisting goods, it is easy to cause the crane to deflect laterally when it is not parallel to the force, causing derailment. When manually handling the derailment of the crane, the severity of the derailment should be checked on site. Generally, there are more cases of two wheels derailing at the same time on one side, and fewer cases of four wheels derailing at the same time. When two wheels derail, first use steel plates, channel steels and other items to pave a temporary track at the position of the derailed wheel. After the temporary tracks on both sides are laid, two people in a group use a pipe drill to clamp the rotating shaft of the crane, release the brake of the crane, and perform manual turning in turns. Be careful not to flash back and forth to make the crane move slowly. If necessary, the guide chain can be used to pull the body to prevent the body from moving to the left. The manual turning and the guide chain can be used at the same time until the wheels are reset.

[0003] Therefore, the existing processing method uses steel plates, channel steels and the like to pave a temporary track at the position of the derailed large wheel. The reliability of the temporary track is uncontrollable and easy to dislocate; and the manual operation is time-consuming and labor-intensive, and the processing efficiency and safety are low. Summary of the invention

[0004] The present invention is intended to solve at least one of the technical problems existing in the prior art. To this end, the present invention provides a method for processing a derailment of a traveling vehicle, the purpose of which is to improve the derailment processing efficiency.

[0005] In order to achieve the above object, the technical solution adopted by the present invention is: a method for processing a derailment of a traveling vehicle, comprising the steps of:

[0006] S1. Preparation before resetting;

[0007] S2. Reset the driving trolley;

[0008] Wherein, the step S1 comprises:

[0009] S101, fixing the wheels at the first position of the traveling trolley, so that the wheels at the first position of the traveling trolley are in an on-track state;

[0010] S102, the wheels at the second position of the traveling trolley are in a derailed state, a support plate is arranged below the wheels at the second position of the traveling trolley, and the support plate is placed on the first guide rail and the first temporary rail;

[0011] S103, a first backrest is arranged at a third portion of the traveling trolley, and a wheel portion at the third portion of the traveling trolley is in an on-track state;

[0012] S104, setting a second backrest at the fourth portion of the traveling trolley, and placing the wheels of the fourth portion of the traveling trolley on the second temporary track.

[0013] The step S2 comprises:

[0014] S201, releasing the wheel brakes of the traveling vehicle;

[0015] S202, jacks are respectively arranged at the third and fourth parts of the traveling vehicle, and the jacks at the third and fourth parts work simultaneously;

[0016] S203, using the first part of the trolley as the overall rotation fulcrum of the trolley, adjusting the posture of the trolley so that the fourth part of the trolley is close to the second guide rail, and at the same time, the wheels at the second part of the trolley roll along the support plate until the first part of the trolley is aligned with the third part, and the wheels at the fourth part of the trolley fall on the second guide rail;

[0017] S204, lifting the second part of the traveling trolley, removing the support plate, and making the wheels at the second part of the traveling trolley fall on the first guide rail;

[0018] S205, resetting the wheel brakes of the traveling vehicle.

[0019] S206: Test run.

[0020] The first temporary track and the second temporary track are parallel to the first guide rail and the second guide rail.

[0021] The length of the first temporary track is 1000 mm.

[0022] The length of the second temporary track is 1500 mm.

[0023] In step S102, the second part of the traveling trolley is firstly lifted, and then the first temporary track is laid under the second part of the traveling trolley so that the first temporary track is parallel to and has the same height as the first guide rail, and then a support plate is placed on the first guide rail and the first temporary track, and finally the support plate is fixed.

[0024] The support plate is connected to the first guide rail and the first temporary rail by welding.

[0025] The distance between the second temporary track and the second guide rail is 450-550 mm.

[0026] The method for processing derailment of a traveling carriage of the present invention has the following advantages:

[0027] 1. Safe and practical;

[0028] Before this invention, after the derailed vehicle was lifted up by a jack, it was directly hit by a vehicle of the same span to return it to its original position. This method has too many uncontrollable factors, such as if the collision force is too small, the derailed vehicle cannot be reset; if the collision force is too large, it is easy to derail again; at the same time, the collision itself will cause further damage to the equipment and cause secondary accidents. However, when using the present invention to carry out operations, you only need to find the corresponding materials and tools, and all work is controllable, which is both safe and practical;

[0029] 2. Economical and efficient;

[0030] Before this invention, the crane was used for operation. The crane weighs 300,000 kg. According to the height of the factory and the lifting angle, at least two 250T truck cranes were required. It was also quite difficult to equip the slings. According to the drawings, the crane beam is 2900 mm high and the trolley is 2700 mm high, so the slings must be about 15,000 mm and the diameter must be ≥∮60 mm. However, they could not be found at that time and had to be purchased from outside. It took a long time, and there was no suitable place on the ground to park the crane for operation. However, through this method, it can be completed without spending too much cost, and the advantages are obvious. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] It should be noted that, in the following embodiments, the "first", "second", "third" and "fourth" do not represent an absolute distinction in structure and / or function, nor do they represent a sequence of execution, but are merely for the convenience of description.

[0036] like Figure 1 As shown, the present invention provides a method for handling derailment of a traveling vehicle, comprising the following steps:

[0037] S1. The preparation work before resetting is mainly to make the traveling carriage have the conditions for lateral movement (after derailment, the wheels of the traveling carriage are lower than the height of the first guide rail and the second guide rail), so as to increase the height of the derailed wheels;

[0038] S2. Reset the traveling trolley.

[0039] like Figure 1 As shown, the above step S1 includes:

[0040] S101, fixing the wheels at the first position of the traveling trolley, so that the wheels at the first position of the traveling trolley are in an on-track state;

[0041] S102, the wheels at the second position of the traveling trolley are in a derailed state, a support plate is arranged below the wheels at the second position of the traveling trolley, and the support plate is placed on the first guide rail and the first temporary rail;

[0042] S103, a first backrest is arranged at a third portion of the traveling trolley, and a wheel portion at the third portion of the traveling trolley is in an on-track state;

[0043] S104, setting a second backrest at the fourth portion of the traveling trolley, and placing the wheels of the fourth portion of the traveling trolley on the second temporary track.

[0044] Specifically, if Figure 1 As shown, the first part, the second part, the third part and the fourth part of the traveling carriage are distributed in a rectangular shape, and the first part, the second part, the third part and the fourth part of the traveling carriage are respectively located at the four right angles of the rectangle. The first part of the traveling carriage has a wheel and two horizontal guide wheels, and the wheel and the two horizontal wheels are located on the first guide rail. The wheel is in an on-track state, and there is a horizontal guide wheel on each side of the first guide rail. When resetting, the first part is used as the rotation base point. The wheel at the second part of the traveling carriage is separated from the first guide rail and is in a derailed state. Two wheels are arranged at the third part of the traveling carriage, one of which is in a derailed state, and one-half of the other wheel is still on the second guide rail. Three wheels are arranged at the fourth part of the traveling carriage, and all three wheels are in a derailed state. The wheel at the fourth part of the traveling carriage is located between the first guide rail and the second guide rail.

[0045] In the above step S101, a fixing plate is arranged on the first part of the traveling trolley, and the fixing plate limits the position of the wheel at the first part of the traveling trolley, so as to prevent the wheel at the first part of the traveling trolley from moving on the first guide rail, and fix the position. The fixing plate is welded to the track beam, and the first guide rail is also arranged on the track beam.

[0046] In the above step S102, the wheel at the second part of the traveling trolley is located outside the first guide rail, and the wheel is 500mm away from the first guide rail at its farthest point. First, use a jack with a working capacity of 100 tons to lift the second part of the traveling trolley, and raise the second part of the traveling trolley to a height of 35mm from the rail surface of the first guide rail. Then, lay the first temporary track under the second part of the traveling trolley, so that the first temporary track is parallel to the first guide rail and has the same height. Then, place a support plate on the first guide rail and the first temporary track, and finally fix the support plate. The support plate provides support for the second part of the traveling trolley. The first temporary track is parallel to the first guide rail and the second guide rail.

[0047] In the above step S102, the support plate used is a steel plate. The support plate is arranged below the wheel at the second part of the traveling trolley. The support plate is welded to the first guide rail and the first temporary rail. The thickness of the support plate is 30 mm, the length of the support plate is 1000 mm, and the width of the support plate is 600 mm. It has high strength and good reliability.

[0048] In the above step S103, a first backrest is set at the third part of the traveling trolley, and the first backrest shall not be welded on the rail surface to prevent cracking due to different materials. The first backrest is used to place the jack, and the wheel part at the third part of the traveling trolley is in the track state.

[0049] In the above step S104, a second backrest is set at the fourth part of the traveling vehicle, and the second backrest is used to place the jack. The second temporary track is parallel to the first guide rail and the second guide rail, and the distance between the second temporary track and the second guide rail is 450-550 mm, and the length of the second temporary track is greater than the length of the first temporary track.

[0050] Preferably, the length of the first temporary rail is 1000 mm, the length of the second temporary rail is 1500 mm, and the distance between the second temporary rail and the second guide rail is 500 mm.

[0051] The above step S2 comprises:

[0052] S201, releasing the wheel brakes of the traveling vehicle;

[0053] S202, jacks are respectively arranged at the third and fourth parts of the traveling vehicle, and the jacks at the third and fourth parts work simultaneously;

[0054] S203, using the first part of the trolley as the overall rotation fulcrum of the trolley, adjusting the posture of the trolley so that the fourth part of the trolley is close to the second guide rail, and at the same time, the wheels at the second part of the trolley roll along the support plate until the first part of the trolley is aligned with the third part, and the wheels at the fourth part of the trolley fall on the second guide rail;

[0055] S204, lifting the second part of the traveling carriage, removing the support plate, and making the wheels at the second part of the traveling carriage fall on the first guide rail;

[0056] S205, resetting the wheel brakes of the traveling vehicle.

[0057] S206: Test run.

[0058] In the above step S202, a jack is set on the first backing, and the working capacity of the jack is 50 tons. Another jack is set on the second backing, and the working capacity of the jack is 50 tons. The jacks at the third and fourth positions work simultaneously, and the third and fourth positions of the traveling trolley are lifted up simultaneously, so that the height of the wheels at the third and fourth positions of the traveling trolley is higher than the rail surface height of the second guide rail.

[0059] In the above step S202, the two jacks work at the same time, and the jacking and padding are carried out simultaneously. If the pad needs to be replaced, one jack must keep working and move carefully with a small range of movement, otherwise it will cause a secondary accident and the consequences may be more serious.

[0060] In the above step S203, first, raising blocks are set under the third and fourth parts of the trolley, and then the jacks located at the third and fourth parts of the trolley can be removed, and the raising blocks provide support for the third and fourth parts of the trolley, and then the first part of the trolley is used as the overall rotation fulcrum of the trolley, and the posture of the trolley is adjusted to make the trolley rotate around the first part (the rotation center line is a vertical line), the second part of the trolley moves along the support plate, and the third and fourth parts of the trolley move along the raising blocks respectively, and finally the first part of the trolley is aligned with the third part, the first part and the third part are on the same horizontal line perpendicular to the length direction of the first guide rail and the second guide rail, and the wheels at the third and fourth parts of the trolley move to above the second guide rail.

[0061] In the above step S204, first use a jack to simultaneously lift the third and fourth parts of the trolley, then take out the raising blocks under the third and fourth parts of the trolley, and then control the third and fourth parts of the trolley to descend, so that the wheels of the third and fourth parts of the trolley fall on the second guide rail; then use a jack to lift the second part of the trolley, so that the wheels at the second part of the trolley are separated from the support plate, and then the support plate can be removed, and then the second part of the trolley is controlled to descend, so that the wheels at the second part of the trolley fall on the first guide rail.

[0062] In the above step S205, the brakes of the traveling trolley are reset, and the reset status of each wheel is carefully determined. When the status is good, the weldments, temporary tracks and jacks of each part are removed.

[0063] In the above step S206, after safety is confirmed, a test run is performed.

[0064] The present invention is described above by way of example in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-mentioned methods. As long as various non-substantial improvements are made using the method concept and technical solution of the present invention; or the above concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.
