Description

TECHNICAL FIELD

[0001] The utility model relates to a diversion device, especially to a diversion device of switch turnout position, belongs to railway diversion technical field. BACKGROUND

[0002] Generally speaking, the switch is one of important weak equipment of railway. The switch turnout part is easy to displace under the action of long time use or heavy load train, when the track gauge size exceeds the allowable error range of standard track gauge, it needs to carry out diversion operation. The operation of changing the position of another rail according to the specified track gauge value is called diversion. The diversion is to correct the track gauge exceeding the limit or close to the limit and its change rate, and eliminate the adverse direction of the line. If the diversion operation is not timely, the maximum track gauge is exceeded, which will seriously affect the safety of train operation and easily cause train accidents.

[0003] The traditional way usually uses a crowbar to push, a rail or a basic rail to move inward or outward, so as to achieve the purpose of diversion. Because the operation tool is simple and relatively backward, it not only wastes time and effort, but also has low operation efficiency, and the crowbar is easy to slide and hurt the hands and feet of the operator, causing personal injury. Some diversion devices use the form of hooking the rail head to pull outward, which can cause the rail head to tilt outward and the rail foot to turn upward, without considering the technical requirement of moving the position of the lower part of the rail as a whole horizontally during the diversion operation. When the hydraulic rail lifting device pushes the point rail outward, the point rail is tilted upward and cannot be moved horizontally. The basic rail and the point rail cannot be moved horizontally to the outside of the switch to achieve the purpose of diversion.

[0004] After retrieval, the Chinese utility model patent with patent No. CN202021788051.2 discloses a simple diversion device for track switch turnout position, which comprises a rail bottom clamp, a diversion main rod, a first cross rod and a second cross rod. The first cross rod and the second cross rod are arranged in parallel, and the middle part of the first cross rod and the second cross rod along the length direction is provided with a through hole penetrating through the first cross rod and the second cross rod. The rail bottom clamp is connected to one end of the diversion main rod along the length direction of the diversion main rod, and the other end of the diversion main rod penetrates through the through holes of the first cross rod and the second cross rod in sequence. The first cross rod and the second cross rod are symmetrically provided with drive cylinders on the two sides of the diversion main rod, the cylinder body part of the drive cylinder is connected vertically on the first cross rod, and the drive rod of the drive cylinder is connected vertically on the second cross rod. One end of the diversion main rod located on the second cross rod is provided with an external thread, and a clamping nut is threadedly connected to the one end of the diversion main rod located on the second cross rod. In the above existing diversion device, the patent still has the following defects:

[0005] 1. The device needs to cross two sleepers, the structure size is large, the railway worker needs to walk to the switch position, and the device is not convenient to carry;

[0006] 2. The rails at the turnout location are staggered, and the switch area also contains switch machinery, switch rail tie rods and other structures. Space is limited, and the structure of this device is large, so it is easily obstructed and cannot be used during use.

[0111] Specifically, the shape and size of the hexagonal sleeve hole 821 are adapted to the shape and size of the fixing bolt 93 on the base plate 91.

[0112] Further, the reverse support plate 7 is the same in shape and structure as the support plate 1, wherein the hole position lengthening pipes 22 on the support plate 1 and the top plate 2 are oppositely arranged with the hole position lengthening pipes 22 on the reverse support plate 7.

[0113] In the utility model, when in use, the top plate 2 is arranged above the sleeper 92 outside the support plate 1. The specific steps of the above embodiment 2 in specific use are as follows:

[0114] Step 1: Firstly, the T-shaped bolts, elastic strips, rail supports and gauge blocks outside the rail 9 in the range before and after the track change should be disassembled;

[0115] Step 2: Assemble the push-pull bracket assembly. Insert the two force transmission rods 3 from the front end of the support plate 1 into the two sliding holes 11 respectively, pass through the support plate 1 through the hole position lengthening pipes 22, then screw the limiting nuts 4 on the force transmission rods 3, make the limiting nuts 4 as close to the non-threaded section end as possible, then pass through the top plate 2 through the hole position lengthening pipes 22 and the limiting holes 21 of the top plate 2, then screw the limiting nuts 4 at the rear end of the force transmission rods 3; make the force transmission rods 3, the support plate 1, the top plate 2 and the reverse support plate 7 form an integral whole;

At this time, the basic rail 94 diversion is completed, and then the point rail 95 diversion operation is carried out;

[0120] Point rail 95 diversion operation:

[0121] After the basic rail diversion is completed, the distance between the two point rails 95 and the two basic rails 94 will change due to the diversion of the basic rail 94, so adjustment shims need to be added to both ends of the tie rod between the two point rails 95 to ensure that the mutual distance between the two point rails 95 and the two basic rails 94 meets the technical requirements;

[0122] Step 5.1: Loosen the tie rod bolt between the point rails 95;

[0124] Step 5.3: Close the oil return valve of the jack 5, shake the operating handle of the hand pump 52, and use the support plate 1, the base plate 91, or the reverse support plate 7, the fixed bolt 93 as the support back, the piston of the jack 5 is elongated, pushing the top plate 2 to move horizontally, the pushing force of the jack 5 is transmitted to the rail foot of the point rail 95 through the top plate 2 and the force transmission rod 3; so that the point rail 95 moves outward or inward of the turnout, after reaching the target, insert appropriate adjustment shims into the end of the point rail 95 tie rod, and tighten the point rail 95 tie rod bolt; ensure that the mutual distance between the two point rails 95 and the two basic rails 94 meets the technical requirements;

[0125] Step 6: After the operation, loosen the jack 5 oil return valve, remove the hydraulic jack and push-pull support assembly;

[0126] Finally, over time, when all the operating work is completed, the operator only needs to carry the various components of the utility model through the corresponding handling equipment or directly through manual to carry them to the designated tool storage warehouse for storage, in preparation for the next cycle of use.

[0127] In the above entire embodiment, a hook is welded at each end of the support plate 1 and the top plate 2, for installing a tension spring, which is connected to the corresponding hook at each end of the support plate 1 and the top plate 2. Specifically, the two tension springs are both stainless steel springs with a wire diameter of 2 mm, an outer diameter of 20 mm, and a length of 110 mm, one end of which is installed on the support plate 1 and the other end of which is installed on the top plate 2, for loosening the hydraulic jack 5 oil return valve and making the jack 5 automatically retract.

[0128] In this embodiment, the positioning sleeve 8 at the top of the support plate 1 is used to be sleeved on the fixing bolt 93 of the base plate 91 when in use, for fixing the support plate 1 and the reverse support plate 7, and providing support force for the reverse pushing of the top plate 2 by the jack 5. The limiting block 33 in the middle of the force transmission rod 3 provides a limiting support point for the reverse pushing of the steel rail 9, and the limiting nuts 4 on both sides of the limiting holes 21 on the top plate 2 are used to limit the position of the top plate 2 on the force transmission rod 3. By adjusting the limiting nuts 4 to adjust the position of the top plate 2 on the force transmission rod 3, the effective length of the force transmission rod 3 can be adjusted.

[0129] In this embodiment, as shown in Figure 6 , 7 The reverse support plate 7 is a steel plate with a length of 380 mm, a height of 65 mm, and a thickness of 15-20 mm, and has one through hole with a diameter of 26 mm on each side. A hole position extension pipe 22 with a length of 50 mm, an inner diameter of 26 mm, and an outer diameter of 40 mm is welded at the front end of each through hole. When the single force transmission rod 3 is too long, it is convenient for the force transmission rod 3 to pass through the reverse support plate 7 through the through hole and the hole position extension pipe 22, preventing the reverse support plate 7 from limiting the adjustment of the effective length of the force transmission rod 3. A reinforcing rib 23 is welded inside the hole position extension pipe 22 to improve the strength of the support plate 1. The two right-angle edges of the reinforcing rib 23 are 50 mm long.

[0130] In this embodiment, as shown in Figure 6 , 7 The positioning sleeve 8 is used to provide a support limiting point for the reverse support plate 7, limiting the reverse support plate 7 on the fixing bolt 93. The positioning bracket 81 is used to install the sleeve ring 82, and the sink in the middle of the positioning bracket 81 is used to support the sleeve ring 82. The hexagonal sleeve hole 821 in the middle of the sleeve ring 82 is a regular hexagon structure, slightly larger than the size of the fixing bolt 93 on the base plate 91.

[0131] In the present embodiment, as shown in Figure 6 , 7 The distance between the limiting block 33 and the draw hook 31 is slightly larger than the width of the rail foot of the rail 9, and the force transmission rod 3 is placed by first rotating the draw hook 31 and the limiting block 33 on the force transmission rod 3 to a horizontal position, and then extending and placing the force transmission rod 3 to the position, and then rotating the force transmission rod 3 by 90 degrees, and then turning the draw hook 31 and the limiting block 33 upward, so that the draw hook 31 and the limiting block 33 are clamped on both sides of the rail foot of the rail 9.

[0132] Finally, it should be noted that the above description is only a preferred embodiment of the present application, and is not intended to limit the present application in other forms. Any skilled person in the art can modify or change the above disclosed technical content to obtain equivalent embodiments. However, any simple modification, equivalent change and modification of the above embodiments without departing from the technical scheme of the present application, and according to the technical essence of the present application, still belongs to the protection scope of the technical scheme of the present application.
