A sleeper mold comb plate structure with anti-bounce function

Abstract

This utility model belongs to the field of railway sleeper mold technology and discloses a railway sleeper mold comb plate structure with anti-bounce function, including a comb plate body. This anti-bounce railway sleeper mold comb plate structure, through the setting of the comb plate body, the Z-shaped steel bars, and the constraint iron plate structure, allows for the following operation: The Z-shaped steel bars are vertically placed between two symmetrically welded constraint iron plates on the comb plate body, and manually pressed down so that their ends are engaged with the pre-set steel bars inside the mold, forming a stable constraint structure. When the railway sleeper mold vibrates, this structure restricts the displacement of the comb plate body in the horizontal and vertical directions, and absorbs some vibration energy through the elastic deformation capacity of the Z-shaped steel bars, mitigating vibration impact. This effectively prevents the comb plate body from bouncing upwards due to vibration, ultimately achieving the beneficial effects of ensuring accurate internal steel bar layout, avoiding steel bar deformation, and improving the quality and performance of railway sleeper products.

Description

Technical Field

[0001] This utility model belongs to the field of railway sleeper mold technology, specifically relating to a railway sleeper mold comb plate structure with anti-bounce function. Background Technology

[0002] Railway sleepers are crucial components in railway track structures, laid on the ballast or track bed to support and secure the rails. They bear the pressure from the rails and evenly transfer it to the track bed, ensuring track stability and smoothness during train operation. Sleepers also maintain track gauge consistency, preventing track displacement due to external forces. Traditionally, sleepers were primarily made of wood, but modern sleepers widely utilize concrete and steel to adapt to different track conditions and load-bearing requirements.

[0003] Existing sleeper mold comb plate structures mainly rely on manual fixing or simple clip devices to prevent bouncing, but they have the following problems: manual fixing requires operators to constantly adjust and fix the comb plate during vibration, which is cumbersome and inefficient, and it is difficult to guarantee stability and accuracy; while simple clip devices have limited structural strength and are prone to loosening or falling off under severe vibration, which cannot effectively restrain the comb plate, and the installation and disassembly process is also inconvenient, failing to meet the requirements of modern sleeper production for stability and efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide a sleeper mold comb plate structure with anti-bounce function. Its purpose is to solve the problems of existing technology, which mainly relies on manual fixing or simple buckle devices, resulting in cumbersome operation, low efficiency, poor reliability, and inability to effectively prevent the comb plate from bouncing during vibration.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a rail sleeper mold comb plate structure with anti-bounce function, including a comb plate body, a constraint iron sheet fixedly installed on the surface of the comb plate body, a through hole opened on the surface of the constraint iron sheet, and a Z-shaped steel bar engaged and connected inside the through hole; it also includes a limiting mechanism, the limiting mechanism including a sliding block slidably installed inside the comb plate body, a locking block fixedly installed on one side surface of the sliding block, and a locking groove opened on the side surface of the Z-shaped steel bar.

[0006] Furthermore, the surface of the comb plate body is provided with through-holes for reinforcing bars.

[0007] Furthermore, the constraint iron sheet is provided in two sets, and the two sets of constraint iron sheets are welded and installed on the surface of the comb plate body in a figure-eight shape.

[0008] Furthermore, a sliding groove is provided on the inner surface of the comb plate body, and an adjusting screw is rotatably installed inside the sliding groove.

[0009] Furthermore, an adjustment groove is provided on one side surface of the comb plate body, and an adjustment knob is rotatably installed inside the adjustment groove. The adjustment knob is fixedly installed at one end of the adjustment screw.

[0010] Furthermore, the surface of the adjustment knob is provided with hexagonal holes.

[0011] Furthermore, a sealing gasket is fitted onto the inner side of the adjustment groove.

[0012] Furthermore, a limiting rod is fixedly installed inside the sliding groove, the sliding block is slidably installed on the surface of the limiting rod, and the sliding block is threadedly installed on the surface of the adjusting screw.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. Through the design of the comb plate body, the Z-shaped steel bars, and the constraint iron plate structure, during use, the Z-shaped steel bars are placed vertically between the two symmetrically welded constraint iron plates on the comb plate body, and manually pressed down so that both ends are engaged with the pre-set steel bars in the mold, forming a stable constraint structure. When the sleeper mold vibrates, this structure restricts the displacement of the comb plate body in the horizontal and vertical directions, and absorbs some vibration energy through the elastic deformation capacity of the Z-shaped steel bars, mitigating vibration impact. This effectively prevents the comb plate body from bouncing upward due to vibration, ultimately achieving the beneficial effects of ensuring accurate internal steel bar layout of the sleeper, avoiding steel bar deformation, and improving the quality and performance of the sleeper product.

[0014] 2. Through the set limiting mechanism, the Z-shaped steel bar is inserted into the through hole of the constraint iron plate. After the Z-shaped steel bar is positioned, the hexagonal tool is inserted into the hexagonal hole. The adjustment knob is turned to make the adjustment screw rotate, so that the sliding block installed on the thread of the adjustment screw slides toward the Z-shaped steel bar, so that the locking block is locked into the locking groove on the side surface of the Z-shaped steel bar, thereby locking the position and rotation angle of the Z-shaped steel bar. This achieves the benefit of maintaining the absolute stability of the constraint structure under strong vibration environment, preventing loosening and failure, and significantly improving the reliability of the device and the production quality of sleepers.

[0021] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0022] Example 1 Reference Figure 1 and Figure 4 This is the first embodiment of the present invention, which provides a sleeper mold comb plate structure with anti-bounce function. This sleeper mold comb plate structure with anti-bounce function includes a comb plate body 1. A constraint iron sheet 4 is fixedly installed on the surface of the comb plate body 1. A through hole is opened on the surface of the constraint iron sheet 4, and a Z-shaped steel bar 3 is engaged and connected inside the through hole.

[0023] The surface of the comb plate body 1 is provided with through-holes for reinforcing bars 2.

[0024] Two sets of constraint iron plates 4 are provided, and the two sets of constraint iron plates 4 are welded and installed on the surface of the comb plate body 1 in a figure-eight shape.

[0025] During use, the main body 1 of the reinforcing bar plate is hoisted above the sleeper mold, aligning the two sets of V-shaped restraint plates 4 with the pre-set rebar slots inside the mold. The operator vertically inserts the Z-shaped rebars 3 into the through holes of the restraint plates 4, ensuring that both ends are parallel to the rebar axis inside the mold. The main body 1 of the reinforcing bar plate is lowered to the bottom of the mold, and the main rebar is inserted through the rebar holes 2 and its position adjusted, allowing the Z-shaped rebars 3 to naturally open under pressure, their ends automatically engaging with the pre-set transverse rebar mesh nodes inside the mold. At this point, the restraint plates 4, through their V-shaped layout, create a bidirectional clamping force on the Z-shaped rebars 3, which, combined with the positioning effect of the main rebars in the rebar holes 2, forms a three-dimensional stable system. When the vibration table is started, the elastic structure of the Z-shaped rebars 3 absorbs high-frequency vibration energy, and their surface threads generate self-locking friction with the hole walls of the restraint plates 4. Simultaneously, the V-shaped plates disperse the vibration stress to the entire main body 1 of the reinforcing bar plate, effectively suppressing the vertical displacement of the reinforcing bar plate and ensuring that the rebar skeleton maintains its design accuracy during concrete vibration.

[0026] Example 2 Reference Figures 2-5 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that it also includes a limiting mechanism 6. The limiting mechanism 6 includes a sliding block 608 that is slidably installed on the inner side of the comb plate body 1. A card block 609 is fixedly installed on one side surface of the sliding block 608, and a card groove 601 is opened on the side surface of the Z-shaped steel bar 3.

[0027] A sliding groove 602 is provided on the inner surface of the comb plate body 1, and an adjusting screw 605 is rotatably installed inside the sliding groove 602.

[0028] An adjustment groove 603 is provided on one side surface of the comb plate body 1. An adjustment knob 604 is rotatably installed inside the adjustment groove 603. The adjustment knob 604 is fixedly installed at one end of the adjustment screw 605.

[0029] The surface of the adjustment knob 604 has a hexagonal hole 607.

[0030] A sealing gasket 5 is fitted into the inner side of the adjusting groove 603.

[0031] A limiting rod 606 is fixedly installed inside the sliding groove 602, and a sliding block 608 is slidably installed on the surface of the limiting rod 606. The sliding block 608 is threadedly installed on the surface of the adjusting screw 605.

[0032] During use, after the Z-shaped rebar 3 is inserted into the through hole of the restraining iron plate 4, a hexagonal wrench is inserted into the hexagonal hole 607 of the adjusting knob 604. Turning the adjusting knob 604 clockwise drives the adjusting screw 605 to rotate, causing the sliding block 608 to slide directionally along the limiting rod 606 via threaded transmission. The sliding block 608 drives the locking block 609 to move towards the side surface of the Z-shaped rebar 3 until the locking block 609 is fully embedded in the preset locking groove 601 of the Z-shaped rebar 3. At this time, the mechanical cooperation between the locking groove 601 and the locking block 609 forms a double lock: both restricting the axial displacement of the Z-shaped rebar 3 and constraining its circumferential rotation. The sealing gasket 5 in the adjusting groove 603 prevents concrete slurry from entering the sliding groove 602. During vibration, the limiting mechanism 6 maintains the clamping force through the self-locking characteristic of the threaded pair, and the interlocking structure of the locking block 609 and the locking groove 601 further eliminates the micro-movement space of the Z-shaped steel bar 3, so that the constraint system can still maintain zero gap connection under strong vibration conditions, significantly improving the long-term stability of the comb plate positioning.

[0033] The remaining structure is the same as that in Example 1.

[0034] Based on embodiments 1 and 2, the working principle of this utility model is as follows: First, the comb plate is smoothly transported to the vicinity of the sleeper mold, ensuring that the Z-shaped steel bar 3 is vertically upward and positioned between the two constraint iron plates 4; then, the comb plate is placed into the sleeper mold, and its position is adjusted so that it is tightly attached to the iron baffle inside the mold and perpendicular to the bottom surface of the mold; next, the operator holds the top of the Z-shaped steel bar 3 with both hands and applies even force to press it down. Under the pressure, the two right-angled sides of the Z-shaped steel bar 3 will slightly open to adapt to the position of the iron plate hole and the internal space of the mold. As the pressing operation proceeds, the two ends of the Z-shaped steel bar 3 gradually protrude from the iron plate hole, and the position after protrusion can be precisely locked onto the pre-set steel bar inside the mold. At this time, the Z-shaped steel bar 3, the constraint iron plate 4, and the steel bar inside the mold together form a stable constraint structure, firmly fixing the comb plate. When the sleeper mold is placed on the vibrating table and begins vibration, the comb plate is subjected to high-frequency vibration force generated by the concrete compaction. However, because the ends of the Z-shaped steel bars 3 are stuck on the steel bars inside the mold, their displacement in the horizontal and vertical directions is restricted. At the same time, the restraining iron plates 4 are tightly connected to the comb plate by welding, further preventing the comb plate from jumping. Throughout the vibration process, the Z-shaped steel bars 3 absorb some of the vibration energy by virtue of their own elastic deformation capacity, mitigating the impact of vibration on the comb plate and maintaining effective restraint on the comb plate at all times, keeping the comb plate stable within the mold and preventing it from affecting the sleeper production quality due to jumping. After each sleeper production is completed, use brushes, compressed air, and other tools to clean the concrete residue on the surface of the comb plate and anti-jump device, keep the device surface clean, and check whether there are cracks or signs of detachment at the welded joints between the restraining iron plates 4 and the comb plate, and whether the Z-shaped steel bars 3 are deformed or broken. If any problems are found, record them in time and report them for repair or replacement.
