Technical Field

[0001] This utility model relates to the field of railway maintenance technology, and in particular to a positioning device for disassembling shear reinforcement bars of ballastless track. Background Technology

[0002] Ballastless track is a track structure that uses a monolithic track bed of concrete, asphalt, etc., instead of the traditional crushed stone track bed. It is mainly composed of precast and cast-in-place track slabs, base plates, fastening systems, and adjustment layers. Its core advantages are high stability, low maintenance requirements, and long service life. It can effectively reduce vibration and deformation during train operation and ensure smooth high-speed train operation. The shear reinforcement of ballastless track is the core shear-resistant component in the high-speed railway track structure. It is pre-embedded in the track slab and fixed by a torque wrench to resist interlayer shear force, prevent cracking, and enhance the ductility of concrete.

[0003] The existing ballastless track system mostly relies on manual dismantling when removing shear reinforcement, which may damage the surrounding structure and easily lead to concrete cracking. It is also impossible to dismantle and position shear reinforcement of different sizes.

[0004] Therefore, those skilled in the art have provided a positioning device for dismantling shear reinforcement in ballastless tracks to solve the problems mentioned in the background art. Utility Model Content

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Reference Figures 1-5 The present invention provides an embodiment of a positioning device for disassembling shear reinforcement of ballastless track, comprising two fixed plates and two movable plates. Each of the two fixed plates has a sliding groove in the middle of its opposite side. Each of the two fixed plates has a clamping component fixedly installed on the opposite side of its lower end face. Each of the two movable plates has an adjusting component fixedly installed at both the front and rear ends of its opposite side. Each of the two movable plates has a slider fixedly installed in the middle of its opposite side. Each of the two adjusting components has a positioning component fixedly installed in the middle of its opposite side. A base plate is fixedly installed on the lower part of the middle of one side of the two fixed plates, and a guide sleeve is installed through the middle of the upper surface of the base plate.

[0019] Specifically, a sliding groove is provided in the middle of the opposite side of the fixed plate, allowing the slider in the middle of the opposite side of the moving plate to slide in a T-shape within the groove. This causes the adjusting and positioning components between the moving plates to move up and down. The clamping component on the opposite side of the lower end of the fixed plate facilitates clamping and fixing the fixed plate and the track plate, improving stability during disassembly. The distance between the track plates is adjusted by the adjusting component between the moving plates. The positioning component on the opposite side of the adjusting component facilitates positioning and clamping of the shear reinforcement, improving the efficiency and stability of disassembling and cutting the shear reinforcement.

[0020] Reference Figure 1 , Figure 2 , Figure 3 The two clamping components include two cavities, four movable rods and two extrusion plates. Each of the four movable rods is fitted with a strong spring. A connecting plate is fixedly installed in the middle of the lower end face of each of the two extrusion plates. A clamping plate is fixedly installed at the lower end of each of the two connecting plates. The two extrusion plates are slidably sleeved around the four movable rods at their front and rear ends respectively. Foot pedals are fixedly installed in the middle of the opposite side of the two clamping plates. Four strong springs are fixed to the front and rear sides of the lower end of the two extrusion plates and the front and rear sides of the two cavities respectively.

[0021] Specifically, a strong spring around the movable rod is fixed between the extrusion plate and the cavity, connecting the lower end of the extrusion plate to the clamping plate. The clamping plate pulls the extrusion plate to compress the strong spring and generate a rebound. The extrusion plate slides around the movable rod, making it easy to pull when adjusting the clamping plate. The clamping plate is clamped and adjusted by a foot pedal on the opposite side of the clamping plate, which is even more convenient.

[0022] Reference Figure 1 , Figure 2 , Figure 4 The adjustment assembly includes an adjustment box, a bidirectional telescopic rod, and two positioning rods. Movable plates are fixedly installed on opposite sides of the two positioning rods, and movable holes are opened inside the adjustment box. Two movable plates are slidably installed inside the movable holes, and a bidirectional telescopic rod is fixedly installed between the two movable plates.

[0023] Specifically, the movable plate on the opposite side of the positioning rod in the adjustment assembly slides within the movable hole inside the adjustment box. During the sliding process, the bidirectional telescopic rod is squeezed, so that the adjustment assembly adjusts the distance to the track plate synchronously.

[0024] Reference Figure 1 , Figure 2 , Figure 5The positioning assembly includes a rectangular plate, a first positioning sleeve, a second positioning sleeve, four reverse threads, a third positioning sleeve, and a circular hole. A bearing sleeve is fixedly installed on the upper inner side of the circular hole, and positive threads are fixedly installed on the lower inner sides of the first, second, and third positioning sleeves. Four reverse threads are respectively set on the upper inner side of the first positioning sleeve, the upper inner side of the second positioning sleeve, the lower part of the whole body, and the lower part of the whole body of the third positioning sleeve. The lower part of the first positioning sleeve is rotatably sleeved on the inner side of the bearing sleeve. A fixing sleeve is fixedly set at the lower end of the rectangular plate at the opening of the round hole.

[0025] Specifically, a rectangular plate is set in the positioning assembly, and a circular hole in the center of the rectangular plate facilitates the passage of shear reinforcement. A bearing sleeve on the upper inner side of the circular hole allows the first positioning sleeve to rotate inside. The positive threads on the lower inner side of the first, second, and third positioning sleeves match the texture on the shear reinforcement, facilitating threaded connection, positioning, and limiting the shear reinforcement. Reverse threads are respectively set on the upper inner side of the first positioning sleeve, the upper inner side of the second positioning sleeve, and the lower outer side of the third positioning sleeve. The lower outer side of the first positioning sleeve rotates and fits inside the bearing sleeve, facilitating easy disassembly of the first, second, and third positioning sleeves. The appropriate type is selected according to the size of the shear reinforcement. The fixed sleeve at the lower end of the rectangular plate at the opening of the circular hole allows the distance between it and the guide sleeve to be used for disassembly and cutting of the shear reinforcement within the distance using an angle grinder, improving the positioning effect for disassembly and cutting of the shear reinforcement and enabling positioning of different sizes.

[0026] Working principle: When disassembling and cutting shear reinforcement in ballastless track, the distance between the track plates is adjusted by the adjusting components between the moving plates, and then the clamping components at the lower end of the fixed plate clamp and fix the fixed plate to the bottom of the track plate, improving the stability of disassembling and cutting the shear reinforcement. The shear reinforcement passes through the guide sleeve on the base plate. According to different sizes of shear reinforcement, the first, second, and third positioning sleeves in the positioning components are selected, and the shear reinforcement is threadedly connected to the shear reinforcement through the positive threads on the inner side of the first, second, and third positioning sleeves. It moves downward so that the distance between the fixed sleeve and the guide sleeve can only accommodate the angle grinder cutting blade, so that the shear reinforcement is in a vertical state and fixed. The angle grinder is attached to the guide sleeve to disassemble and cut the shear reinforcement, which facilitates the positioning and disassembly of shear reinforcement of different sizes and prevents the concrete cracking problem that is easily caused by manual disassembly and cutting without positioning and fixation.

[0027] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
