Abstract
Description
Technical Field
[0001] This utility model relates to the field of level crossing plate technology, specifically a straight groove level crossing plate. Background Technology
[0002] A level crossing board is a facility installed at road or railway intersections to ensure traffic safety. Level crossing boards are typically made of metal or concrete and have a certain height and strength to effectively separate the railway and highway crossing areas. Traditional slotted level crossing sleepers have several problems during use, such as the easy accumulation of dust and gravel. The dust and gravel in the gaps increase friction between the sleeper and the ground, thus accelerating damage, reducing safety, and increasing maintenance costs. Furthermore, the materials and structure of level crossing sleepers are susceptible to wear and tear, freeze-thaw cycles, and other environmental factors, leading to frequent replacement and maintenance. Utility Model Content
[0003] The technical problem to be solved by this utility model is to provide a straight groove crossing plate that is not prone to accumulating dust, sand and gravel, and reduces replacement and maintenance.
[0004] To solve the above-mentioned technical problems, this utility model includes a plate body, the structural features of which are: a steel cage supporting concrete is provided inside the plate body, a filling hole is provided on the plate body, two parallel rail support grooves are provided on the plate body, the depth of the rail support grooves is higher than the height of the rail, a fastener sleeve for fixing the rail is provided in the rail support groove, multiple lifting sleeves are embedded in the plate body, the multiple lifting sleeves are symmetrically arranged between each other, and an isolation layer that can fit the plate body is provided on the four sides and the bottom surface of the plate body.
[0005] With the above structure, the steel reinforcement cage inside the slab supports the slab body, and the slab body is formed by filling the mold through the filling hole. The slab body has parallel rail support grooves for placing two rails. The depth of the rail support grooves is greater than the height of the rails, so that after the rails are installed in the rail support grooves, the upper end face of the rail will not be higher than the upper end face of the level crossing slab body. This prevents vehicles from causing fluctuations when they pass over the level crossing slab due to running over the rails, and also prevents the rails from being affected, thus ensuring safety. Fastener sleeves are installed in the rail support grooves, and fasteners can be installed in the fastener sleeves to fix the position of the rails. To prevent rail displacement and ensure train safety, multiple lifting sleeves are nested within the slab. These sleeves are used to lift the slab, and their symmetrical arrangement ensures the stability of the slab's movement during lifting. An isolation layer is attached to the four axes and bottom surface of the slab, filling the gap between the slab and the ground. Adjacent slabs also contact each other through the isolation layer. By filling the gaps with the isolation layer, dust and sand are prevented from entering, thus avoiding wear and tear on the slab, reducing replacement and maintenance, and lowering maintenance costs.
[0006] The isolation layer is fixed around the plate by adhesive. The isolation layer is fixed to the four axes and bottom surface of the plate by adhesive, which is convenient and reduces production costs.
[0007] The isolation layer and the board are bonded together with polyurethane adhesive or epoxy resin adhesive. Polyurethane adhesive has good bonding strength, is resistant to freeze-thaw cycles and high temperatures, and dries quickly, making it suitable for bonding the board to isolation layers made of other materials. Epoxy resin adhesive has good adhesion, does not pollute the environment, and can resist the erosion of various chemicals, thus having good bonding performance and ensuring the reliability of the isolation layer bonding.
[0008] The isolation layer is made of EPDM rubber, which has good economic efficiency, is resistant to aging and corrosion, has good elasticity, can squeeze and fill gaps, protect the board, avoid wear on the board, and play a role in isolation and protection.
[0009] The thickness of the isolation layer is 1.8mm. Using an isolation layer of this thickness can ensure toughness while avoiding displacement of the plate due to compression caused by an excessively thick isolation layer, thus ensuring the stability of the plate position and protecting the safety of train operation.
[0010] The hoisting sleeves are provided in eight parts, and are respectively set on the front and rear faces of the plate. The hoisting sleeves are symmetrically arranged, with a total of eight hoisting sleeves, four on the front face and four on the rear face. The symmetrical arrangement of the four hoisting sleeves ensures that the hoisting sleeves are evenly stressed during hoisting, avoiding skewing or damage caused by uneven stress, and ensuring the stability and safety of hoisting.
[0011] The shape of the isolation layer is consistent with the end face shape of the plate being bonded. Through holes are opened on the isolation layer on the front and rear faces of the plate. The position of the through holes is consistent with the position of the lifting sleeve. By ensuring that the shape of the isolation layer is consistent with the shape of the plate, the bonding between the plates is guaranteed, while avoiding interference between the isolation layer and the rail groove. The through holes on the isolation layer on the front and rear faces avoid the opening of the lifting sleeve, ensuring that interference is avoided during the lifting process.
[0012] In summary, this utility model has the advantages of reducing wear on the level crossing plate, increasing the lifespan of the level crossing plate, and reducing maintenance costs. Attached Figure Description
[0013] Figure 1 This is a schematic diagram of the structure of this utility model; Figure 2 for Figure 1 A structural diagram viewed from the right. Detailed Implementation
[0014] like Figure 1 , 2 As shown, this utility model is a straight-groove crossing slab, which includes a track slab body 1. A reinforcing cage for supporting concrete is provided inside the slab body 1. A rail-bearing groove 3 for receiving the rail is provided on the slab body 1. Multiple fastener sleeves 4 are installed in the rail-bearing groove 3 to fix the rail, so that the rail is installed in the rail-bearing groove 3 of the straight-groove crossing slab. For ease of description, let... Figure 1 Left is left, right is right; Figure 1 The top side is the front, and the bottom side is the back; let... Figure 1 The left and right directions are horizontal, and the front and back directions are vertical. The sides and bottom of the crossing plate are fitted with an isolation layer 6, which reduces the friction between the sides and bottom of the crossing plate and the ground, thereby reducing damage to the crossing plate.
[0015] like Figure 1 , 2 As shown, the plate 1 has two filling holes 2 in the middle. During the production of the straight groove track slab, cement is poured into the mold through the filling holes 2 to produce the track slab. In this utility model, the rail bearing groove 3 is arranged horizontally on both sides, so the rail is placed horizontally in the rail bearing groove 3. Lifting sleeves 5 are provided on the front and rear sides of the plate 1. The lifting sleeves 5 are used to lift and move the track slab, improving the moving efficiency. The lifting sleeves 5 on the front and rear sides are symmetrically arranged. The symmetrical arrangement ensures the stability of the track slab during lifting and avoids the instability of the lifting sleeve on one side, which could lead to breakage and tilting of the track slab on one side, thus ensuring the stability of the lifting. Multiple fastener sleeves 4 are provided on the rail bearing platform. Each rail bearing platform has two rows of fastener sleeves 4, and the two rows of fastener sleeves 4 are arranged alternately on both sides. Multiple fastener sleeves 4 within each row of fastener sleeves 4 are parallel to each other. Through the staggered arrangement of the fastener sleeves 4, the rail is fixed in the rail bearing groove 3, ensuring the stability of the rail position and preventing the rail from shaking or shifting. This ensures the stability of the rail from all angles.
[0016] like Figure 1 , 2 As shown, when the level crossing plate is installed in the frog position, there is a gap between the level crossing plate and the bottom surface, and there is also a gap between adjacent level crossing plates. Dust and sand can easily fall into the gaps, causing friction between the plate bodies 1 and between the plate body 1 and the bottom surface, which in turn leads to damage to the plate body 1. After setting the isolation layer 6 on the bottom surface of the plate body 1, the gap between the plate body 1 and the bottom surface is sealed by the isolation layer 6, preventing dust and sand from entering the gap, avoiding damage caused by friction of the plate body 1, and ensuring the service life of the level crossing plate. By ensuring the sealing between the level crossing plates, the vehicle is prevented from bumping, and the vehicle is prevented from individually squeezing the edge of the plate body 1, further ensuring the service life of the plate body 1 and preventing wear of the plate body 1.
[0017] like Figure 1 , 2As shown, in this embodiment, the material of the isolation layer 6 is EPDM rubber. The isolation layer 6 is adhered to the four ends and bottom surface of the plate 1 using polyurethane adhesive or epoxy resin adhesive. EPDM rubber offers high cost-effectiveness and economic value. Simultaneously, EPDM rubber exhibits excellent wear resistance and aging resistance, enabling it to withstand various outdoor weather conditions and ensuring long-term use and service life. The wide operating temperature range of EPDM rubber allows this straight-groove crossing plate to be suitable for different environments, increasing its reliability. By adhering the isolation layer 6 with polyurethane adhesive or epoxy resin adhesive, the bottom and four sides are respectively adhered, resulting in a more secure and comfortable fit, facilitating the installation of the isolation layer 6. The isolation layer 6 adhered to the bottom surface of the plate 1 has the same shape as the ground surface of the plate 1. The isolation layers 6 on the left and right sides have the same shape as the front and rear end faces of the plate 1. Therefore, the isolation layers 6 on the left and right sides also have downward-facing clearance grooves, the positions of which are consistent with the rail bearing grooves 3. These grooves fit snugly to protect the plate 1 while preventing interference with rail installation. The isolation layers 6 on the front and rear end faces of the plate 1 are consistent with the front and rear end faces of the plate 1. The isolation layers 6 have through holes at the locations of the lifting sleeves 5, the size of which is larger than the diameter of the lifting sleeves 5. These through holes on the isolation layers 6 at the front and rear end faces ensure the stability of the straight-groove crossing plate during lifting and prevent interference. In this embodiment, the thickness of the isolation layer 6 is 1.8 mm. Using this thickness ensures durability while preventing displacement of the plate 1 due to compression caused by the isolation layer 6 being too thick, thus ensuring the stability of the plate 1 and protecting the safety of train operation.
