Description

Technical Field

[0001] The invention relates to a fish plate gluing device and a gluing process, belonging to the technical field of fish plates. Background Art

[0002] Fishplates, also known as fishtail clamps, play a connecting role at rail joints. However, due to factors such as temperature changes and train operation, the rails will be subjected to pressure and longitudinal tension, resulting in creep between the rails and the fishplates, which in turn affects the stability of the connection. In the prior art, workers usually apply a layer of glue between the fishplate and the rails. By utilizing the bonding effect of the glue, the fishplate and the rails can be more tightly connected together, thereby enhancing the stability of the connection.

[0003] After the glue is applied, it usually takes about 24 hours for the glue to cure. Therefore, the trains in the relevant sections will not be able to run during this period, resulting in travel disruptions for passengers and delays in cargo transportation. If the glue is not cured and the train is running, the glue will gradually loosen or fail due to vibration, causing the connection between the fishplate and the rail to become unreliable, which in turn affects the stability and safety of the train operation.

[0004] Based on the above situation, the present invention proposes a fish plate gluing device and a gluing process, which can effectively solve the above problems. Summary of the invention

[0005] The technical problem to be solved by the present invention is to provide a fishplate gluing device and a gluing process, which solves the problem in the prior art that after actual gluing, since it generally takes about 24 hours for the glue to solidify, the trains in the relevant sections cannot run during this period, resulting in obstruction of passenger travel and delay of cargo transportation. If the glue is not solidified and the train is running, the glue will gradually loosen or fail due to vibration, thereby causing the connection between the fishplate and the rail to become unreliable, thereby affecting the stability and safety of the train operation.

[0006] The technical problem to be solved by the present invention is achieved by adopting the following technical scheme: a fishtail plate gluing device, characterized in that it includes a mold plate, both sides of the mold plate are concavely provided with film-forming cavities for the fishtail plate to be inserted, the inner surface of the film-forming cavity is used for applying glue to stick the fishtail plate, and the bottom of the mold plate is provided with a heating plate at a position below the two film-forming cavities, the two heating plates are connected by a wire, and one end of the wire is connected to an external power supply through a plug, and the top of the mold plate and the bottom of the heating plate are provided with insulation components.

[0007] By adopting the above technical solution, you only need to connect the plug to the power supply, and then apply glue on the inner surface of the two film-forming cavities. Among them, the two heating plates after power-on heat the mold plate, thereby heating the glue, thereby shortening the curing time of the glue. At the same time, under the heat preservation effect of the insulation component, the heat loss is reduced, and the curing of the glue is further accelerated. When the glue is cured to a certain extent, fishtail plates are placed on the top of the glue in the two film-forming cavities, so that the fishtail plates and the glue are bonded. Finally, the fishtail plate and the glue are removed from the mold plate together, and the fishtail plate can be glued to the rail with glue.

[0008] Through the structure of the present application, the glue is heated to shorten the curing time of the glue. After the glue is stuck to the rail, the glue can be completely cured in a short time, without 24 hours, so it will not affect the normal operation of the train, and will not cause the glue to gradually loosen or fail due to vibration, thereby ensuring a reliable connection between the fishplate and the rail, and ensuring the stability and safety of the train operation.

[0009] The present invention is further configured as follows: the heat preservation component comprises a heat preservation plate arranged at the bottom of the two heating plates.

[0010] By adopting the above technical solution, when the heating plate heats the bottom of the mold plate, the heat generated by the heating plate will be dispersed to the surroundings, and the insulation plate can effectively block the heat loss, so that the heat generated by the heating plate can be more concentrated on the mold plate, thereby improving the heating efficiency.

[0011] The present invention is further configured as follows: the insulation component also includes insulation covers respectively located above the two film forming cavities, the two insulation covers are removable and arranged on the top of the mold plate, both ends of the insulation cover are provided with clamping blocks, and the top of the mold plate is provided with a clamping slot for the clamping block to be inserted.

[0012] By adopting the above technical solution, when the heat preservation cover is used to prevent heat dissipation inside the mold plate, the two clamping blocks on the two heat preservation covers are respectively inserted into the two clamping grooves on the top of the mold plate, and the heat preservation cover can be fixed on the top of the mold plate.

[0013] The present invention is further configured as follows: a plurality of baffles for clamping the ends of the mold plate are arranged at both ends of the heat-insulating cover.

[0014] By adopting the above technical solution, when the insulation cover is fixed on the top of the mold plate, the two baffles seal the two ends of the mold plate, which more effectively prevents the heat inside the mold plate from being lost.

[0015] The present invention is further configured as follows: both ends of the two thermal insulation covers are detachably connected to the mold plate through fixings, the fixings include a clamping rod, a protrusion 2 is provided on the baffle plate, a round hole 4 for the clamping rod to be inserted into is formed on the protrusion 2, a number of protrusions 1 are provided on both sides of the mold plate, a number of protrusions 1 are provided with round holes 3 for the clamping rod to be inserted into, a contact piece is provided on the outer peripheral wall of the clamping rod, an opening is provided on the end of the clamping rod, a spiral groove is provided on the inner wall of the opening, and a round rod for inserting into the opening and the spiral groove is provided at the bottom of the protrusion 1.

[0016] By adopting the above technical solution, when the heat preservation cover needs to be pressed and fixed on the top of the mold plate, the card block is inserted into the card slot so that the circular hole three and the circular hole four are aligned, and then the clamping rod is aligned with the circular hole four, and the clamping rod is moved downward to pass through the circular hole four and inserted into the circular hole three. At this time, the round rod is also inserted into the opening, and then the clamping rod is continued to move downward and rotated so that the round rod is inserted into the spiral groove, and the clamping rod can be limited in the vertical direction so that the clamping rod does not slide out of the circular hole three and the circular hole four. When the clamping rod moves downward, the abutment sheet is also driven to move downward, so that the bottom of the abutment sheet abuts against the top of the protrusion two, thereby applying downward pressure to the protrusion two, and then the bottom of the protrusion two and the top of the protrusion one are pressed against each other, and the bottom of the baffle is driven to be pressed downward to fit the top of the two ends of the mold plate, so that the heat preservation cover can be pressed and fixed on the top of the mold plate.

[0017] The present invention is further configured as follows: a plurality of reference blocks are provided at both ends of the mold plate at positions of the bottom walls of the two film-forming cavities.

[0018] By adopting the above technical solution, the thickness of the positioning block is referred to when applying the glue, and the thickness of the glue is the same as the thickness of the positioning block.

[0019] The present invention is further configured such that rubber strips are adhered to the positions of the heat-insulating cover on both sides of the clamping block.

[0020] By adopting the above technical solution and setting the rubber strip, the connection between the bottom of both ends of the insulation cover and the top of the mold plate is further sealed, and the insulation effect is higher.

[0022] Step 1: Connect the wire to the power supply and turn on the power supply to heat the mold plate;

[0023] Step 2: Apply silicone film on the surfaces of the mold plates in the two film-forming cavities;

[0024] Step 3: Apply a layer of glue on the top surface of the silicone film, then lay a layer of felt on the top surface of the glue, and finally apply another layer of glue on the top surface of the felt layer;

[0025] Step 4: Use the insulation component to insulate the mold plate, and then heat the glue until it has no fluidity;

[0026] Step 5: Move the insulation assembly and glue the fishplate to the top surface of the glue;

[0027] Step 6: Remove the silicone film, glue and fish plate from the mold plate;

[0028] Step 7. Tear off the silicone film and stick the glued side of the fishplate onto the rail.

[0029] By adopting the above technical solution, in the actual process of applying glue, only the glue needs to be applied on the surface of the mold plate, and when the contact area between the fish plate and the rail is large and the shape is irregular, there will be no waste of glue. Moreover, the cured glue is flat on the surface of the rail, ensuring that the overall aesthetics of the rail is not affected.

[0030] The beneficial effect of the present invention is that it is only necessary to connect the plug to the power supply, and then apply glue on the inner surface of the two film-forming cavities. Among them, the two heating plates after power-on heat the mold plate, thereby heating the glue, thereby shortening the curing time of the glue. At the same time, under the heat preservation effect of the heat preservation component, the heat loss is reduced, and the curing of the glue is further accelerated. When the glue is cured to a certain extent, fishtail plates are placed on the top of the glue in the two film-forming cavities, so that the fishtail plates and the glue are bonded. Finally, the fishtail plate and the glue are removed from the mold plate together, and the fishtail plate can be glued to the rail with glue.

[0031] Through the structure of the present application, the glue is heated to shorten the curing time of the glue. After the glue is stuck to the rail, the glue can be completely cured in a short time, without 24 hours, so it will not affect the normal operation of the train, and will not cause the glue to gradually loosen or fail due to vibration, thereby ensuring a reliable connection between the fishplate and the rail, and ensuring the stability and safety of the train operation.

DETAILED DESCRIPTION

[0041] In order to make the technical means, creative features, objectives and effects of the present invention easier to understand, the present invention is further described below in conjunction with specific Figures 1-8.

[0042] like Figure 1 and Figure 2 As shown, it includes a mold plate 1 with an ω-shaped cross-section, and both sides of the mold plate 1 are concave to form a film-forming cavity 2 for the fishtail plate 29 to be inserted, and the inner surface of the film-forming cavity 2 is used to apply glue to stick the fishtail plate 29, and the bottom of the mold plate 1 is located below the two film-forming cavities 2 and is fitted with a heating plate 3 for heating the mold plate 1. Wires 6 are fixedly connected to the two heating plates 3, and one end of the two wires 6 is combined into one wire 6 and connected to a plug 26, which is externally connected to a power supply. Insulation components are provided on the top of the mold plate 1 and the bottom of the heating plate 3. In the present embodiment, the material of the heating plate 3 is electrically conductive and thermally conductive. In another embodiment, the cross-section of the mold plate 1 includes but is not limited to an ω-shape, and can also be a U-shape, and is arranged in a horizontal parallel or vertical parallel form based on the U-shape.

[0043] When it is necessary to use glue to stick the fishplate 29 to the surface of the rail, just connect the plug 26 to the power supply, and then apply glue on the inner surface of the two film-forming cavities 2. Among them, the two heating plates 3 after power-on heat the mold plate 1, thereby heating the glue, thereby shortening the curing time of the glue. At the same time, under the heat preservation effect of the insulation component, the heat loss is reduced, and the curing of the glue is further accelerated. When the glue is cured to a certain extent, fishplates 29 are placed on the top of the glue in the two film-forming cavities 2, so that the fishplates 29 and the glue are bonded. Finally, the fishplates 29 and the glue are removed from the mold plate 1 together, and the fishplates 29 can be glued to the rails with glue.

[0044] Through the structure of the present application, the glue is heated to shorten the curing time of the glue. After the glue is stuck to the rail, the glue can be completely cured in a short time, without 24 hours, so it will not affect the normal operation of the train, and will not cause the glue to gradually loosen or fail due to vibration, thereby ensuring a reliable connection between the fishplate 29 and the rail, ensuring the stability and safety of the train operation, and will not cause obstruction to passenger travel and delay in cargo transportation, nor will it cause inconvenience to the public and economic development.

[0045] Among them, the setting of the insulation component isolates the external environment from the interior of the mold plate 1, so that a relatively closed environment is formed inside the mold plate 1, reducing heat loss to the outside through air convection and conduction, effectively reducing heat loss, further shortening the heating time, and improving work efficiency.

[0046] In addition, in the actual process of applying glue, the glue only needs to be applied on the surface of the mold plate 1. When the contact area between the fish plate 29 and the rail is large and irregular in shape, glue waste will not occur. Moreover, the cured glue is flat on the surface of the rail, ensuring that the overall aesthetics of the rail is not affected.

[0047] like Figure 1-Figure 3 As shown, the heat preservation assembly includes a heat preservation plate 4 which is fixed to the bottom of the two heating plates 3 and has the same shape as the mold plate 1 and is ω-shaped. In this embodiment, the material of the heat preservation plate 4 has heat preservation and heat insulating properties.

[0048] Among them, several circular holes 7 are equidistantly opened at both ends and the middle end of the mold plate 1 along the length direction of the mold plate 1, and several circular holes 8 are equidistantly opened at both ends and the middle end of the insulation board 4 along the length direction of the insulation board 4. Nuts 27 are fixed at the bottom of the insulation board 4 below the circular holes 8, and bolts 9 are removably set in the circular holes 1 7, the circular holes 2 8 and the nuts 27.

[0049] In addition, through holes 25 for the wires 6 to pass through are provided on both sides of the middle end of the bottom of the insulation board 4 .

[0050] The insulation component also includes an insulation cover 5 located above the two film forming cavities 2 respectively. The two insulation covers 5 are both detachable and arranged on the top of the mold plate 1. The bottoms of the two insulation covers 5 at both ends along the length direction are integrally formed with a clamping block 11. The top of the mold plate 1 is provided with a clamping groove 12 for the clamping block 11 to be inserted along the length direction. Both ends of the insulation cover 5 along the width direction are perpendicular to the insulation cover 5 and are integrally formed with a baffle 13 for inserting into the end of the mold plate 1. Both ends of the mold plate 1 are provided with a fixing groove 28 for the baffle 13 to be inserted.

[0051] During the heating process, when the thermal insulation cover 5 is to be used to prevent internal heat dissipation, the two blocks 11 on the two thermal insulation covers 5 only need to be respectively inserted into the two slots 12. At the same time, the baffles 13 on both sides of the thermal insulation cover 5 are inserted into the two fixing slots 28. The thermal insulation cover 5 can be fixed on the top of the mold plate 1, thereby isolating the external environment from the interior of the mold plate 1, so that a relatively closed environment is formed inside the mold plate 1, reducing heat loss to the outside through air convection and conduction, effectively reducing heat loss, further shortening the heating time, and improving work efficiency.

[0052] The heat preservation plate 4 and the mold plate 1 are fixed by a plurality of bolts 9 which are inserted into the circular hole 1 7 , the circular hole 2 8 and the nut 27 .

[0053] like Figure 3-Figure 6 As shown, both ends of the two insulation covers 5 are detachably connected to the mold plate 1 through fixings, and the fixings include a clamping rod 14. A second protrusion 16 is integrally formed on one side of the baffle 13, and a fourth round hole 18 is provided on the second protrusion 16 for the clamping rod 14 to be inserted. A protrusion 15 is integrally formed on one side of both ends of the mold plate 1 along the width direction, and a third round hole 17 is provided on the protrusion 15 for the clamping rod 14 to be inserted.

[0054] Among them, a contact piece 19 is integrally formed on the outer peripheral wall of the clamping rod 14 at the position on the top of the second protrusion 16, an opening 21 is opened at the bottom of the clamping rod 14, a spiral groove 20 is opened on the inner wall of the opening 21, and a round rod 22 for inserting into the opening 21 and the spiral groove 20 is fixed at the bottom of the protrusion 15.

[0055] In addition, a rotating ring 23 is fixed to the top of the pressing rod 14 .

[0056] When the heat preservation cover 5 needs to be pressed and fixed on the top of the mold plate 1, the clamping block 11 is inserted into the clamping groove 12 so that the circular hole 3 17 and the circular hole 4 18 are aligned, and then the clamping rod 14 is aligned with the circular hole 4 18, and the clamping rod 14 is moved downward to pass through the circular hole 4 18 and clamped into the circular hole 3 17. At this time, the round rod 22 is also clamped into the opening 21. Then, the clamping rod 14 is further moved and rotated by the rotating block so that the round rod 22 is clamped into the spiral groove 20, and the clamping rod 14 can be limited in the vertical direction so that the clamping rod 14 does not slip out of the circular hole 3 17 and the circular hole 4 18, so that the protrusion 2 16 fits with the protrusion 1 15.

[0057] Among them, when the clamping rod 14 moves downward, it drives the abutment sheet 19 to move downward as well, so that the bottom of the abutment sheet 19 abuts against the top of the protrusion 2 16, thereby applying downward pressure to the protrusion 2 16, and then the bottom of the protrusion 2 16 and the top of the protrusion 1 15 are pressed against each other, and at the same time, the bottom of the baffle 13 is fit with the top of the two ends of the mold plate 1, so that the insulation cover 5 and the mold plate 1 can fit more closely, ensuring that the gap between the mold plate 1 and the insulation cover 5 is tightly closed to prevent heat leakage, enhance the sealing inside the mold plate 1, and further improve the curing efficiency.

[0058] When it is necessary to remove the insulation cover 5, it is only necessary to rotate the clamping rod 14 counterclockwise so that the round rod 22 is located at the connection point between the opening 21 and the spiral groove 20, and then move the clamping rod 14 away from the mold plate 1 to make the round rod 22 disengage from the clamping rod 14, thereby releasing the connection and fixation between the protrusion 1 15 and the protrusion 2 16, and then the insulation cover 5 can be removed from the mold plate 1.

[0059] In addition, the provision of the rotating ring 23 makes the operation of the pressing rod 14 more convenient and improves the flexibility of the pressing rod 14 .

[0060] like Figure 2 and Figure 8 As shown, a plurality of reference blocks 10 are fixed at both ends of the mold plate 1 at the positions of the inner bottom walls of the two film-forming cavities 2, and the reference blocks 10 are used to control the amount of glue injected.

[0061] Refer to the thickness of the positioning block when applying glue. The thickness of the glue should be the same as the thickness of the positioning block.

[0062] like Figure 3 As shown, rubber strips 24 are attached to the heat-insulating cover 5 at positions on both sides of the clamping block 11 .

[0063] The provision of the rubber strips 24 further makes the connection between the bottom of both ends of the heat-insulating cover 5 and the top of the mold plate 1 more tightly sealed, and the heat-insulating effect is higher.

[0064] like Figure 7As shown, a gluing process of a fish plate 29 gluing device is implemented based on the above-mentioned fish plate 29 gluing device, and includes the following steps:

[0065] Step 1: Connect the plug 26 to a power source and turn on the power source to heat the mold plate 1;

[0066] Step 2: A silicone film 30 for assisting demoulding is applied to the surfaces of the mold plates 1 in the two film-forming cavities 2;

[0067] Among them, the setting of the silicone film 30, on the one hand, effectively prevents the glue from directly adhering to the mold plate 1, ensures that the glue is smoothly removed from the mold plate 1, and maintains the cleanliness and flatness of the mold plate 1, thereby extending its service life. On the other hand, the silicone film 30 has a certain elasticity and flexibility, and can fill in the tiny defects on the surface of the mold plate 1, making the glue layer more uniform, which helps to improve the precision and quality of the mold, further standardize the size and shape of the final product, and improve production efficiency.

[0068] In this embodiment, the demoulding products include but are not limited to the silicone film 30 , and also include water-based demoulding agents, oil-based demoulding agents, wax-based demoulding agents, and the like.

[0069] Step 3: Apply a glue layer 31 on the top surface of the silicone film 30, then lay a felt layer 32 on the top surface of the glue layer 31, and finally apply a glue layer 33 on the surface of the felt layer 32;

[0070] When applying the first glue layer 31 , the felt layer 32 and the second glue layer 33 , the thickness of the application is based on the thickness of the reference block 10 .

[0071] In this embodiment, the felt layer 32 includes but is not limited to chopped strand mat, woven composite mat, cloth, composite mat, and other glass fibers and their products.

[0072] In the coating process, the coating method is not limited to coating glue layer 1 31 - felt layer 32 - glue layer 2 33 only once, but also a multi-layer felt-to-multi-layer glue method of coating glue layer plus felt layer plus glue layer on top of glue layer 2 33 can be used.

[0073] Step 4: Fix two insulation covers 5 on the top of the mold plate 1 and heat the glue until it has no fluidity;

[0074] Step 5, remove the insulation cover 5, and bond the fish plate 29 to the top surface of the second glue layer 33;

[0075] Step 6: Remove the silicone film 30, the first glue layer 31, the felt layer 32, the second glue layer 33 and the fish plate 29 from the mold plate 1;

[0076] Step 7: When the fish plate 29 needs to be fixed, tear off the silicone film 30, stick the fish plate 29 on the rail with glue, and then fix the fish plate 29 on the rail with bolts 9.

[0077] The above shows and describes the basic principles, main features and advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments.
