In order to bear larger load, in the process of prefabricating the track slab, longitudinal steel bars and transverse steel bars which are distributed in a staggered mode are required to be arranged in a die to form a steel bar net, and then concrete is poured on the basis of the steel bar net, so that the load bearing capacity of the track slab is improved.
In the prior art, in order to improve uniformity of concrete in a mold, the mold after concrete is poured is generally vibrated by a vibrating table, and a common vibrating table provides vibration at both side edges and/or the center below a table body by a large number of vibrators or vibrators. However, the applicant finds that in the research process, the rigidity of the adopted track slab die is extremely high due to the extremely high requirement on the dimensional accuracy of the prefabricated track slab, so that the vibration conduction effect of the die from bottom to top is weaker, the vibration effect of concrete in the die is further limited, a large amount of bubbles are easily remained, the floating slurry problem is serious, and even the track slab product is scrapped when serious; in addition, the mode of completely relying on bottom vibration can also cause the problems of fatigue damage, deformation and the like of the die to be outstanding, and the service life of the die is seriously shortened.
Disclosure of Invention
The application provides a vibrating device and a vibrating method for a prefabricated track slab, which are used for solving the problems of weak vibration transmission capability, short service life of a die and the like in the track slab prefabrication process in the prior art, and achieving the purposes of improving the vibration effect, improving the product quality, reducing the rejection rate and prolonging the service life of the die.
The application is realized by the following technical scheme:
the utility model provides a vibrating device of prefabricated track board, includes the shaking table, is used for the drive a plurality of vibrators of shaking table vibration, with shaking table assorted track board mould still includes the track subassembly that is located the shaking table top, sliding connection is in a plurality of trusss on the track subassembly, sliding connection are in a plurality of first telescoping devices on the truss, with the vibrating rod that first telescoping device links to each other.
Aiming at the problems of weak vibration transmission capability, serious mold loss and the like in the prior vibration mode in the track plate prefabricating process in the prior art, the application provides a vibrating device for prefabricating the track plate. According to the application, the plurality of vibrating rods are inserted into the concrete in the mould from top to bottom for vibration, and can work independently or can work together with the vibrating table, so that the problem of poor bottom vibration conduction effect caused by overlarge template rigidity in the prior art can be solved, the direct rigid vibration impact of the mould can be reduced, and the service life of the mould is prolonged. Compared with the traditional vibration mode which is completely conducted by the bottom, the vibration mode of the application has the advantages that residual bubbles in the concrete are obviously reduced, no floating slurry is basically generated in the mould, the quality of track plate products can be improved, and the rejection rate in the production process can be reduced.
Furthermore, the inventors found during the research that the fatigue damage and deformation of the mold, besides being directly affected by the high frequency vibrations of the bottom, has another very important cause: in the prior art, after the material injection of the track slab mold is completed, the vibrator below is started, and the vibration frequency of the vibrator is gradually increased from 0 to a set value in the starting process of the vibrator, so that at a certain moment in the process, the vibration frequency of the vibrator is easy to be consistent with the natural frequency of the mold, and the mold is further caused to resonate, and although the resonant time is extremely short, irreversible fatigue damage or deformation damage is still caused to the mold, and the prior art is not aware of the technical problem. The application adopts the mode of arranging the vibrating rod above, and can firstly open the vibrating rod, and then insert the vibrating rod into the concrete from top to bottom after the vibrating rod reaches the set vibration frequency, thereby completely overcoming the short-time resonance phenomenon of the mould caused by the gradual rising of the frequency of the vibrator below in the prior art, obviously improving the protection performance of the mould, obviously reducing the risk of fatigue damage or deformation of the mould and further greatly prolonging the service life of the mould.
In addition, the difference of the sizes of the dies of the track plates and the difference of the arrangement of the steel bars in the dies are considered, so that the truss and the first telescopic device can slide, and the position of the vibrating rod can be flexibly adjusted on a plane, so that the stability of the steel bars after binding is prevented from being influenced by contact with the steel bars after the vibrating rod is lowered, and insulation failure between transverse steel bars and longitudinal steel bars is prevented from being caused.
Further, the device also comprises a first driving device for driving the truss to slide along the track assembly and a second driving device for driving the first telescopic device to slide along the truss.
According to the scheme, the truss is driven by the first driving device to slide along the track assembly, so that the truss can carry all vibrating bars to effectively avoid the position of transverse steel bars in the die; the second driving device drives the first telescopic device to slide along the truss, so that the first telescopic device carries the vibrating rod to effectively avoid the position of the longitudinal steel bar. The first driving device drives the truss and the second driving device drives the first telescopic device, which can be any existing driving method realized by a person skilled in the art, and the driving method is not limited herein.
Further, the installation cavity is formed in the bottom surface of the first telescopic device, and the top end of the vibrating rod is assembled in the installation cavity through the flexible assembly. In the research process, the inventor finds that if the vibrating rod is directly connected to the end part of the first telescopic device, the vibration of the vibrating rod can be directly transmitted to the first telescopic device and the truss above the first telescopic device, so that the failure rate of the first telescopic device is extremely high; if the conventional flexible connection mode of adding the flexible connection part is adopted, the vibration rod below cannot be kept vertical, and the vibration rod is likely to be inclined to a greater extent in the process of inserting concrete, vibrating and pulling out the mould, so that the vibration rod staggered with the reinforcing steel bar is close to the reinforcing steel bar and even is in direct contact with the reinforcing steel bar. In order to overcome the problems, the bottom surface of the first telescopic device is provided with the mounting cavity, so that flexible connection between the vibrating rod and the first telescopic device is realized in the mounting cavity through the flexible component, and the top end of the vibrating rod is inserted into the mounting cavity, so that the vibrating rod can be limited by the cavity wall of the mounting cavity to avoid deflection; meanwhile, the flexible component in the device can reduce the interference of the first telescopic device by the vibrating rod, so that the failure rate of the first telescopic device is reduced. It can be seen that the protection of the first telescopic device and the limitation of the vertical direction of the vibrating rod are simultaneously met, and the vibrating rod has important and significant value for normal operation of the vibrating rod.
Further, the flexible component comprises a spring and an arc-shaped elastic sheet; the spring is positioned between the top surface of the vibrating rod and the top surface of the inner wall of the installation cavity; the plurality of arc shell fragments are connected at the vibrting spear outer wall, arc shell fragment concave surface is inwards, and the outer wall and the installation cavity inside wall contact of arc shell fragment.
According to the scheme, the springs are arranged between the top surface of the vibrating rod and the top surface of the inner wall of the installation cavity, so that buffering is provided for longitudinal vibration transmitted to the first telescopic device by the vibrating rod, and the longitudinal vibration interference suffered by the first telescopic device is relieved; through setting up a plurality of arc shell fragments at the vibrting spear outer wall, for the vibrting spear conduction provides the buffering to the lateral vibration of first telescoping device, in order to alleviate the lateral vibration interference that first telescoping device received. One end of the arc-shaped elastic sheet is connected to the outer wall of the vibrating rod, and the other end of the arc-shaped elastic sheet is abutted against the inner side wall of the mounting cavity, so that the vibrating rod has extremely high tension and toughness, and vibration of the vibrating rod in all directions can be digested to a certain extent by utilizing deformation capacity of the vibrating rod. Moreover, the arc-shaped elastic sheet is abutted against the inner side wall of the mounting cavity, so that deflection of the vibrating rod can be limited in all directions, and an automatic deflection correcting effect is achieved. In this scheme arc shell fragment concave surface inwards means that the concave surface is towards the vibrting spear outer wall, and the convex surface is towards the installation intracavity wall.
Further, a plurality of rows of positioning components are annularly and uniformly distributed on the outer wall of the vibrating rod, each group of positioning components comprises a plurality of positioning pieces which are uniformly distributed along the axial direction of the vibrating rod, and clamping grooves are formed in the top surfaces of the positioning pieces; the arc shell fragment top set up with draw-in groove assorted barb portion, arc shell fragment bottom set up with vibrating rod outer wall assorted laminating portion. The connection between the vibrating rod and the arc-shaped elastic sheet is realized through the positioning piece. Wherein, the vibration stick axial can understand as vertically, and a plurality of setting elements form a set of locating component along vertical evenly distributed, have circularly equipartition at the outer wall of vibration stick a plurality of locating component, can fully guarantee the automatic ability of rectifying an incline to the vibration stick and to the digestion ability of the transverse vibration on the first telescoping device. In addition, the arc-shaped elastic sheet is inserted into the clamping groove on the positioning piece through the reversing hook part, so that stable connection can be ensured, and the damaged arc-shaped elastic sheet can be quickly and conveniently replaced independently; the shape of the attaching part is matched with the outer wall of the vibrating rod, so that the contact area between the arc-shaped elastic sheet and the vibrating rod is increased, and the automatic deviation rectifying effect of the arc-shaped elastic sheet is improved.
Further, the bottom of the first telescopic device is detachably connected with an end cover, the end cover is used for shielding the mounting cavity, and a through hole for a vibrating rod to pass through is formed in the end cover; still including fixing the locating part at the vibrting spear outer wall, the locating part is located the installation cavity inside, the locating part can't pass the through-hole, and the locating part is located the below of all arc shell fragments.
In the scheme, the limiting piece is fixedly connected to the outer wall of the vibrating rod, and the limiting piece can be limited through the end cover after the upper end cover is installed, so that the vibrating rod is prevented from falling off; and the limiting piece is positioned below all the arc-shaped elastic pieces so as to ensure that all the arc-shaped elastic pieces play a role in the installation cavity. Any existing detachable connection mode can be adopted between the end cover and the first telescopic device.
Further, the boss is fixedly sleeved on the first telescopic device, a plurality of annular evenly distributed induction devices are arranged at the bottom of the boss, and the induction direction of each induction device faces downwards.
In the use process, the arrangement scheme of the steel bars in the mould can be known in advance, and the positions of the truss and the first telescopic device are adjusted according to the arrangement scheme, so that interference with the steel bars when the vibrating rod moves downwards is avoided. However, in the actual construction operation, errors in positioning, control and the like are unavoidable, and the distance between the vibrating rod inserted into the die and the reinforcing steel bar is too short; because the concrete is not solidified during the operation of the vibrating rod and the vibrating rod vibrates at high frequency, the too close distance easily causes loosening, falling and even insulation failure of binding positions of the longitudinal steel bars and the transverse steel bars, thereby affecting the local bearing capacity of the track plate and interfering signal transmission in the use process due to the insulation failure of the longitudinal steel bars and the transverse steel bars.
In order to overcome the problem, the boss is still established to fixed cover on first telescoping device to this scheme, sets up a plurality of annular equipartitions in boss bottom, induction direction induction system down, induction system is used for responding to whether there is the reinforcing bar to exist under it. The boss in this scheme not only can provide the installation station for each induction system, can also extend the interval between induction system and the vibrting spear. When the sensing device senses that the steel bars are right below the sensing device, the distance between the vibrating rod and the steel bars below the vibrating rod in the direction is too short, so that the vibrating rod can be properly far away from the direction by adjusting the position of the truss or the first telescopic device. Of course, the sensing device in this embodiment may be implemented by a person skilled in the art to sense whether the steel bar exists below, including but not limited to laser, infrared, image recognition, etc.
Further, the truss both ends all set up the second telescoping device, universal joint is connected to second telescoping device bottom, clamping device is connected to universal joint, the clamping device inner wall sets up the flexible pad.
According to the scheme, the second telescopic devices are arranged at the two ends of the truss, the clamping devices are used for clamping the side plates of the die, so that the stability of the truss during equipment working can be improved, the truss can be more stable against vibration from each vibrating rod, and the die can be more integrally and uniformly vibrated through the cooperation of the second telescopic devices and the clamping devices. Wherein, clamping device is used for the centre gripping mould curb plate, owing to have reinforced structures such as strengthening rib, bracing in some mould curb plate outer edges, in order to guarantee this scheme and can both effectively centre gripping to various mould curb plates, especially connect universal joint between second telescoping device and clamping device to satisfy and all can carry out the centre gripping to horizontal strengthening rib, fore-and-aft bracing. In addition, the inner wall of the clamping device is provided with a flexible pad to improve the clamping stability, so that the clamping is prevented from being easy to fail due to vibration.
Further, the cleaning container and the drying container are positioned below the track assembly.
The cleaning container and the drying container in the scheme are both positioned below the track assembly, namely, positioned at the positions where the trusses can carry the vibrating rods to arrive. After the vibration bars are adopted to vibrate from top to bottom, in order to avoid solidification of concrete attached to the vibration bars, the vibration bars are placed into a cleaning container one by one and started to vibrate, so that the vibration bars are cleaned one by one, and solidification of the concrete is avoided. And placing the cleaned vibrating rods into a drying container one by one for drying so as to prevent the vibrating rods from being adhered with water when being used next time, and further affecting the quality of concrete.
