Description

Technical Field

[0001] The invention relates to the field of concrete sleeper production, and in particular to a method and a production system for producing concrete sleepers using a spike-anchoring method. Background Art

[0002] Concrete sleepers are usually produced by the pedestal method and the assembly line method. The pedestal method is that the production processes such as the molding, curing, and demoulding of the sleepers are all carried out at the same place on the pedestal. The assembly line method is produced in the workshop. The entire workshop is divided into several sections according to the requirements of the production process. Each section is equipped with corresponding heat and machinery equipment. The production processes such as the molding, curing, and demoulding of the sleepers are completed in sequence in the corresponding sections. The assembly line method has higher production efficiency than the pedestal method and a higher degree of mechanization. It is currently the commonly used sleeper production method.

[0003] The sleepers play the role of supporting the rails and keeping the position of the rails stable. Therefore, in the construction of railway tracks, it is necessary to anchor the spikes to fix the rails on the sleepers so that the rails and the sleepers are connected as a whole. At present, the sleepers produced by the above two methods are all reserved with anchor holes for the spikes on the sleepers, and are generally transported to the site for laying before anchoring. During anchoring, the anchoring agent is poured into the reserved hole, and then the positioner is used to insert the spikes into the reserved hole. After the anchoring agent solidifies and hardens, the positioner is removed to complete the anchoring construction of the spikes. This method can only anchor the spikes on one side of the sleeper in the rail groove at a time, and cannot be constructed in batches, the efficiency is low, the construction site environment is complex, and it is greatly affected by the climate. Moreover, the anchoring material is easy to flow on the sleepers, pollute the sleepers, and affect the appearance quality of the sleepers. In addition, the laying site anchoring needs to wait for the anchoring agent to solidify and harden before the next step of construction can be carried out, which seriously affects the laying progress of the railway track.

[0004] In order to increase the speed of laying railway tracks and enable the rails to be fixed after the sleepers are transported to the site for laying, some manufacturers will reserve a special site at the sleeper manufacturing base for spike anchoring operations. After the spikes are anchored, they are directly transported to the laying site for laying, saving the time required for on-site construction and waiting for the anchoring agent to solidify. When anchoring, the spike anchoring construction can be carried out layer by layer in the order of the sleeper stack from top to bottom. This method saves space. When there is enough space, the sleepers can be spread out first, and then stacked neatly after the spikes are anchored. Both of these site construction methods require the bottom of the reserved hole for the sleepers to be blocked first. After blocking the bottom of the hole, the anchoring agent is poured into the reserved hole, and the spikes are inserted using a locator. After the anchoring agent solidifies, the locator is removed. Moreover, operations such as dispersing, transporting, and stacking all require manual and mechanical methods to complete, which requires a large workload, requires a lot of equipment, and has high construction costs. Due to the manual blocking of the bottom of the hole, the blocking depth cannot be guaranteed, and the quality cannot be controlled. The spike anchoring construction method is also a scattered method of anchoring the single-side rail groove, which is inefficient. Therefore, a new concrete sleeper production method is urgently needed, which can not only convert scattered sleeper anchoring into mass production, but also ensure the speed of spike anchoring and sleeper production, provide a basis for accelerating the laying of railway tracks, save manpower, and reduce construction costs. Summary of the invention

[0005] The present invention provides a method for producing concrete sleepers by the spike-first anchoring method. The method is used to produce concrete sleepers. The prepared sleepers are firstly anchored with spikes on the sleepers. The sleepers can be directly transported to the laying site for laying and installing rails, thereby providing a basis for accelerating the laying speed of railway tracks.

[0009] (1) Making anchor rods: combining anchoring agent with spikes, and completing the production of anchor rods after the anchoring agent solidifies; (2) installing the prepared anchor rods in the reserved holes of the concrete sleeper steel mold; (3) pouring concrete slurry into the steel mold and demoulding after curing to complete the production of concrete sleepers. This method first combines spikes and anchoring agent to make anchor rods, and then inserts the anchor rods into the sleeper steel mold to produce concrete sleepers. The prepared anchor sleepers have spikes anchored on them. After the sleepers are manufactured, they can be directly transported to the laying site for laying and installing rails, providing a basis for accelerating the laying of railway tracks. In addition, the spike anchoring and sleeper forming are combined into one production line. The spikes can be anchored by a simple method, which can realize mass production and improve production efficiency. Compared with the method of producing sleepers first and then anchoring the spikes in the prior art, the sleeper spreading, transportation, and stacking operations are omitted, which greatly reduces the labor, saves manpower, reduces labor intensity, reduces equipment investment, and saves construction costs. In addition, the operating environment is simple, the floor space is small, it is not affected by the climate, and continuous production is possible. This production method provides a new idea for sleeper prefabrication and can promote the development of concrete sleeper production and rail transit construction technology.

[0010] Preferably, in step (1), the anchor rod is made by using a forming mold, the forming mold has a mold cavity for forming the anchor rod, and a plurality of grooves arranged at intervals are provided in the mold cavity. The grooves are provided in the mold cavity so that the anchor rod made by using the forming mold has outward protrusions, which improves its bonding strength with concrete, improves its pull-out resistance, and ensures stability and durability.

[0011] Preferably, the forming mold includes two modules arranged opposite to each other, each of which is provided with a mold groove, and the mold grooves on the two modules are closed to form the mold cavity. The forming mold is designed as a split structure, which is convenient for processing the grooves therein, and for spraying a demoulding machine into the mold cavity, which is also convenient for demoulding.

[0012] Furthermore, the production of the anchor rod using the molding die includes the following steps: (1.1) spraying a mold release agent into the mold grooves of the two separated modules; (1.2) installing a spike into the mold cavity; (1.3) moving the module so that the mold grooves on the two modules are closed to form the mold cavity; (1.4) pouring an anchoring agent into the mold cavity; (1.5) after the anchoring machine solidifies and hardens, moving one of the modules away from the other module, taking the anchor rod out of the mold groove, and completing the production of the anchor rod. The operation is simple, the process flow is short, and the spike anchoring is performed with the help of a mold without polluting the appearance of the sleeper.

[0013] The present invention also provides a production system for producing concrete sleepers by the spike-anchor method, which is used in the above-mentioned method for producing concrete sleepers by the spike-anchor method, and the prefabricated anchor rods are used in the production of concrete sleepers. The production system includes: an anchor rod forming station, which is provided with a spike anchoring forming mold for anchoring the spikes into anchor rods; a sleeper forming station, which is provided with a sleeper steel mold; a steaming station; a demoulding station, which is provided with a demoulding machine for demoulding the sleeper in the sleeper steel mold; and a transportation system, including a transportation trolley and a transportation track arranged between adjacent stations. The production system will be able to realize streamlined operations such as spike anchoring, sleeper forming, and demoulding, and convert scattered sleeper anchoring into mass production, reducing production costs, and occupying a small area, saving site construction costs.

[0014] The molding die comprises: at least two modules arranged opposite to each other, one of which is a fixed module and the other is a movable module. A mold groove is arranged on the side of each module close to another module. When the two modules arranged opposite to each other are closed, the mold grooves thereon constitute a mold cavity.

[0015] A positioning groove is provided at the center of the bottom of the mold groove, and a receiving groove is provided at the center of the bottom of the positioning groove. The diameters of the mold groove, the positioning groove and the receiving groove are successively reduced to form a step shape. When installing the road spike in the mold cavity, the flange of the middle part of the road spike is placed in the positioning groove, the head of the road spike is located in the mold groove, and the tail is located in the receiving groove. After the two relatively arranged modules are closed, the flange on the road spike is located in the positioning groove and blocks the positioning groove. With such a design, during operation, a positioner is not used, and the road spike is directly installed in the mold groove, and there is no need to use additional materials to block the mold cavity. The construction is simple, the operation steps are shortened, the construction difficulty is reduced, and the anchoring depth of the road spike can be increased to ensure the quality.

[0016] The bottom end of the receiving groove passes through the bottom surface of the module, and its depth is less than the length of the tail of the spike. Since the tail of the spike is located outside the mold, it is easy to demould.

Before step (2), the following steps are required: (a) Spraying a demoulding agent; (b) Installing sleeve stirrups into the steel mold; (c) Inserting steel bars into the mold; (d) Installing accessories; After the above steps are completed, the steel mold is placed on a vibration table, concrete slurry is poured into the steel mold and vibrated, and demoulding is performed using a demoulding machine after slag removal, edge cleaning and curing. In step (2), the anchor rod can be installed in the steel mold by a bolt locking assembly.

[0032] In step (1), an anchor rod is made using a molding die, such as Figure 1 As shown, the forming mold has a mold cavity 1 for forming an anchor rod 2, and a plurality of grooves 3 arranged at intervals are provided in the mold cavity 1. The grooves 3 are provided in the mold cavity 1 so that the anchor rod 2 produced by the forming mold has an outward protrusion, which improves the bonding force between the anchor rod 2 and the concrete, improves the pull-out resistance, and ensures stability and durability.

[0033] like Figure 2 As shown, the molding die includes two modules 4 arranged opposite to each other, each of which is provided with a die groove 5, and the die grooves 5 on the two modules 4 are closed to form a mold cavity 1 (as shown in FIG. Figure 3As shown), in this embodiment, two mold grooves 5 are respectively provided on each module 4. In other embodiments, the number of mold grooves can also be designed according to actual demand. The molding mold is designed as a split structure, which is convenient for processing the grooves therein, and it is convenient to spray the demoulding machine into the mold groove, which is also convenient for demoulding. The depth of the mold groove 5 in this embodiment is consistent with the anchoring depth of the anchor rod 2. In other embodiments not shown in the figure, in order to facilitate the closure of the two modules, a positioning hole is set on one of the modules 4, and a frustum matching the positioning hole is set on the other module 4. In this embodiment, the mold grooves 5 on the two modules 4 form a mold cavity 1 after closing, and the bottom of the groove is naturally blocked after the mold groove 5 is closed to prevent leakage of slurry.

[0034] In this embodiment, see Figures 1 to 3 The manufacturing of the anchor rod using the molding mold includes the following steps: (1.1) spraying a mold release agent into the mold grooves 5 of the two separated modules 4; (1.2) installing a spike 6 into the mold cavity 1; (1.3) moving the modules 4 so that the mold grooves on the two modules 4 are closed to form a mold cavity 1; (1.4) pouring an anchoring agent into the mold cavity 1; (1.5) after the anchoring machine solidifies and hardens, move one of the modules 4 so that the module is away from the other module, take the anchor rod 2 out of the mold groove, and complete the manufacturing of the anchor rod 2. The operation is simple, the process flow is short, and the spike anchoring is performed with the help of a mold without contaminating the sleeper.

[0035] The method of producing concrete sleepers by the spike-first anchoring method of the present invention first anchors the spikes, so that the spikes can be anchored in the production workshop. The spikes are directly anchored in the sleepers produced by the method. Compared with the prior art method of first making sleepers, taking out the stacked sleepers from top to bottom for anchoring, or transporting the sleepers to the construction site for laying and then anchoring the spikes, the scattered sleeper anchoring is converted into mass industrial production, which greatly reduces the labor of workers, reduces labor intensity, improves production efficiency, and has a simple operating environment and a small footprint. In addition, since the sleeper production method is carried out indoors, it is not affected by weather and can be operated continuously.

When installing the spike 6 into the mold cavity 1, the flange of the middle part of the spike 6 is placed in the positioning groove 7, the head of the spike 6 is located in the mold groove 5, and the tail is located in the receiving groove 8. After the two modules 4 arranged oppositely are closed, the flange on the spike 6 is located in the positioning groove 7 and blocks the positioning groove 7. With the mold cavity 1 of this structure, during operation, no positioner is used, and the spike 6 is directly installed in the mold groove 5. Compared with the prior art, no additional material is needed to block the mold cavity. The construction is simple, the operation steps are shortened, the construction difficulty is reduced, and the anchoring depth of the spike can be increased to ensure the quality. In order to facilitate demoulding, the bottom end of the receiving groove 7 passes through the bottom surface of the module 4, and its depth is less than the length of the tail of the spike 6. Since the tail of the spike is located outside the mold, demoulding is convenient.

The demoulding device (such as Figure 5 As shown in the figure, a demoulding module driven by a cylinder or a hydraulic cylinder can be used. The demoulding module 12 is a rectangular block, which is arranged below the anchor rod forming mold. The demoulding cylinder is fixed on the bracket 9. The demoulding module 12 is connected to the telescopic end of the demoulding cylinder. When the two modules 4 are opened, the demoulding cylinder drives the demoulding module 5 to move forward and collide with the tail of the spike, so that the anchor rod is separated from the mold groove 5 to realize dynamic demoulding. The demoulding device has a simple structure and a reasonable design, and can easily demould the formed anchor rod. This embodiment can automatically demould, has a high degree of automation, and has high production efficiency.
