DETAILED DESCRIPTION

[0027] In order to make those skilled in the art better understand the present invention, the present invention is further clearly and completely described below in conjunction with the accompanying drawings and embodiments. It should be noted that, in the absence of conflict, the features in the embodiments and examples of this application can be combined with each other.

[0028] A typical embodiment of the present invention provides a self-propelled hydraulic bridge T-beam template, such as Figure 1 , Figure 2 As shown, it includes a walking frame 1, a walking wheel 2, a lifting frame 3, a traverse frame 4 and a side mold 5. The walking wheel 2 is installed at the bottom of the walking frame 1, the lifting frame 3 is installed at the top of the walking frame 1, the traverse frame 4 is installed on the lifting frame 3, and the side mold 5 is installed on the traverse frame 4.

[0029] The walking wheel 2 can carry the template as a whole to move in the lateral and longitudinal directions, and the walking wheel 2 can rotate 360 ​​degrees to adjust the walking direction.

[0030] Among them, a lifting mechanism for vertically lifting the lifting frame 3 is installed between the walking frame 1 and the lifting frame 3; the lifting mechanism includes a lifting cylinder 6 installed on the walking frame 1 and a lifting and pushing structure arranged between the protruding end of the lifting cylinder 6 and the lifting frame 3.

[0031] Among them, a transverse movement mechanism for laterally moving the transverse movement frame 4 is installed between the lifting frame 3 and the transverse movement frame 4; the transverse movement mechanism includes a transverse movement cylinder 7 installed on the lifting frame 3 and a transverse movement pushing structure arranged between the protruding end of the transverse movement cylinder 7 and the transverse movement frame 4.

[0032] refer to Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 The lifting and pushing structure and the transverse pushing structure have the same structure, and both include a thread sleeve 8, a threaded rod 9, a gear 10, a rack 11 and an elastic telescopic rod 12.

[0033] The protruding ends of the transverse displacement cylinder 7 and the lifting cylinder 6 are respectively connected to an elastic telescopic rod 12, and a rack 11 is installed at the protruding end of the elastic telescopic rod 12. The gear 10 is meshed with the rack 11, and the gear 10 is fixedly sleeved on the end of the screw rod 9. The threaded sleeve 8 is threadedly sleeved on the other end of the screw rod 9, wherein the screw rod 9 in the lifting and pushing structure is rotatably installed on the walking frame 1, and the screw rod 9 in the transverse displacement pushing structure is rotatably installed on the lifting frame 3, and the threaded sleeve 8 in the lifting and pushing structure is fixedly connected to the lifting frame 3, and the threaded sleeve 8 in the transverse displacement pushing structure is fixedly connected to the transverse frame 4.

[0034] The lifting and pushing structure described above is used to lock the lifting frame 3 on the traveling frame 1 when the lifting cylinder 6 removes the supporting force on the lifting frame 3. The lateral pushing structure is used to lock the lateral frame 4 on the lifting frame 3 when the lateral cylinder 7 removes the pushing force on the lateral frame 4.

[0035] According to the above embodiment, the running wheels 2 are arranged to carry the running frame 1 for walking, so that the trackless walking of the whole template can be realized. Specifically, by adjusting the direction of the running wheels 2 to the longitudinal direction, the side mold 5 can be driven to move in the longitudinal direction. When one prefabricated T-beam is completed, the side mold 5 can be moved to the position of another prefabricated T-beam to carry out the work of the next prefabricated T-beam. By adjusting the direction of the running wheels 2 to the transverse direction, the side mold 5 can be displaced in the direction of mold opening and mold closing, so that the side molds 5 on both sides of the prefabricated T-beam can be moved close to or away from the skeleton of the prefabricated T-beam, so as to better cooperate with the mold opening and mold closing operations of the prefabricated T-beam.

[0036] The traverse mechanism controls the displacement of the traverse frame 4 on the lifting frame 3, so that the side mold 5 moves horizontally close to or away from the skeleton of the prefabricated T-beam, thereby realizing the lateral mold opening and closing operations. The lifting mechanism controls the displacement of the lifting frame 3 in the height direction, thereby realizing the rise and fall of the side mold 5. With such an arrangement, the traverse mechanism and the lifting mechanism can be used as the power components for mold opening and mold closing, thereby realizing the purpose of stable and fast operation of the side mold 5.

[0037] In addition, the present embodiment provides a lifting and pushing structure and a lateral pushing structure, so that after the mold is closed, the lifting cylinder 6 and the lateral moving cylinder 7 can respectively remove the supporting force on the lifting frame 3 and the lateral moving frame 4 by retracting. At this time, the lifting frame 3 is locked on the traveling frame 1 by the lifting and pushing structure, and the lateral moving frame 4 is locked on the lifting frame 3 by the lateral pushing structure. Then, the lifting and pushing structure and the lateral pushing structure are used to replace the lifting cylinder 6 and the lateral moving cylinder 7 to respectively support the lifting frame 3 and the lateral moving frame 4, so as to maintain the mold closing state of the side mold 5. In this way, the lifting cylinder 6 and the lateral moving cylinder 7 can be protected from the influence of the vibration force during the casting process, thereby extending the service life of the lifting cylinder 6 and the lateral moving cylinder 7.

[0038] Specifically, the timely locking effect between the screw rod 9 and the wire sleeve 8 is utilized, and the reset stroke of the elastic telescopic rod 12 is utilized. During the mold closing process, the lifting cylinder 6 and the transverse cylinder 7 first compress the elastic telescopic rod 12. When the elastic telescopic rod 12 is compressed to the maximum extent, it pushes the rack 11 to move. The rack 11 drives the gear 10 to rotate, and the gear 10 drives the screw rod 9 to rotate. The screw rod 9 drives the wire sleeve 8 to move linearly, which can realize the displacement of the side mold 5 in the lateral and height directions.

[0039] After the closing operation of the side mold 5 is completed, the lifting cylinder 6 and the lateral cylinder 7 are controlled to be retracted for a distance. The retraction distance of the lifting cylinder 6 and the lateral cylinder 7 should be less than the compression distance of the elastic telescopic rod 12. In the process of retracting the lifting cylinder 6 and the lateral cylinder 7, the lifting cylinder 6 and the lateral cylinder 7 remove the force on the lifting frame 3 and the lateral frame 4. At this time, the lifting frame 3 and the lateral frame 4 are locked by the lifting jacking structure and the lateral jacking structure respectively to ensure that the side mold 5 is stable in the closing state. In the process of pouring concrete, the vibration force will not impact the lifting cylinder 6 and the lateral cylinder 7 through the lifting frame 3 and the lateral frame 4. At the same time, the elastic telescopic rod 12 can achieve a certain vibration buffering for the lifting cylinder 6 and the lateral cylinder 7, so as to avoid the vibration force from damaging the lifting cylinder 6 and the lateral cylinder 7.

[0040] In this embodiment, a sleeve structure with a spring inside is preferably used as the elastic telescopic rod.

[0041] In a preferred embodiment, the wire sleeve 8, screw rod 9, gear 10 and rack 11 in the lifting and pushing structure and the lateral pushing structure are provided with two, the backs of the two racks 11 are fixedly connected, and the two gears 10 are respectively meshed with the two racks 11. Whether it is the lifting and pushing structure or the lateral pushing structure, the two racks 11 can be displaced synchronously and drive the two gears 10 to rotate, so that the combination of the two screw rods 9 and the wire sleeve 8 can simultaneously control the displacement of the lifting frame 3 and the lateral frame 4. The force of the lifting cylinder 6 and the lateral cylinder 7 is more balanced.

[0042] refer to Figure 6 and Figure 8 In a preferred embodiment, the lifting and pushing structure and the transverse pushing structure also include a support plate 13, a sliding sleeve 14, a positioning rod 15, a positioning hole 16 and a spring 17. The support plate 13 is fixedly arranged on the surface of the rack 11, and two sliding sleeves 14 are respectively slidably connected to the two ends of the support plate 13. The side surface of the sliding sleeve 14 is fixedly provided with a positioning rod 15. A plurality of positioning holes 16 for inserting the positioning rod 15 are provided on the walking frame 1 and the lifting frame 3. A spring 17 is provided between the two sliding sleeves 14 to provide elastic force for the positioning rod 15 to insert into the positioning hole 16.

[0043] In the initial state, the elastic force of the spring 17 makes the sliding sleeve 14 located at the outermost position of the support plate 13, and at this time, the positioning rod 15 is inserted into the positioning hole 16. For the lifting and pushing structure, the corresponding positioning rod 15 cooperates with the positioning hole 16 to lock the rack 11, and the meshing action of the rack 11 and the gear 10 is used to lock the screw rod 9, thereby locking the lifting frame 3 at a fixed height. For the lateral pushing structure, the corresponding positioning rod 15 cooperates with the positioning hole 16 to lock the rack 11, and the meshing action of the rack 11 and the gear 10 is used to lock the screw rod 9, thereby locking the lateral frame 4 at a fixed position.

[0044] During the operation of the lifting cylinder 6 and the lateral cylinder 7, the sleeve 14 is first pushed so that the sleeve 14 moves on the support plate 13, thereby compressing the spring 17 and pulling out the positioning rod 15 from the positioning hole 16. When the lifting frame 3 and the lateral frame 4 reach the mold closing position, the threaded cooperation between the screw rod 9 and the screw sleeve 8 can pre-position the lifting frame 3 and the lateral frame 4, and during the retraction of the lifting cylinder 6 and the lateral cylinder 7, the pressure on the sleeve 14 will be first removed, so that the sleeve 14 is reset under the action of the spring 17, and then the positioning rod 15 is reinserted into the positioning hole 16 at the corresponding position. At this time, the lifting cylinder 6 and the lateral cylinder 7 remove the supporting force on the lifting frame 3 and the lateral frame 4, and the lifting frame 3 and the lateral frame 4 are locked and positioned by the lifting and pushing structure and the lateral pushing structure respectively, so as to replace the lifting cylinder 6 and the lateral cylinder 7 to support and position the lifting frame 3 and the lateral frame 4 respectively.

[0045] On the basis of the above implementation modes, relatively specifically, the lifting and pushing structure and the transverse pushing structure also include a push rod 19 and a mounting plate 20. The mounting plates 20 are fixedly mounted on the protruding ends of the lifting cylinder 6 and the transverse cylinder 7, and a push rod 19 is arranged at each end of the mounting plate 20. An isosceles triangle-shaped top groove 18 is opened on the sliding sleeve 14, and the push rod 19 is movably arranged in the top groove 18. The two waist sides of the top groove 18 are symmetrically distributed in the telescopic direction of the lifting cylinder 6 and the transverse cylinder 7. When the push rod 19 moves from the top of the top groove 18 to any end of its bottom side, the positioning rod 15 is pulled out from the positioning hole 16.

[0046] During the process of the lifting cylinder 6 and the traverse cylinder 7 extending forward, the positioning rod 15 is inserted into the positioning hole 16, so that the sleeve 14 will not move forward immediately. At this time, the top rod 19 applies a force to the front inner wall of the top groove 18, so that the sleeve 14 moves and drives the positioning rod 15 to be pulled out of the positioning hole 16. After the positioning rod 15 is pulled out of the positioning hole 16, the extended ends of the lifting cylinder 6 and the traverse cylinder 7 push the rack 11 to move through the sleeve 14 and the support plate 13, so as to drive the screw rod 9 to rotate, so as to adjust the height of the lifting frame 3 and the position of the traverse frame 4.

[0047] After the mold is closed, when the lifting cylinder 6 and the transverse cylinder 7 are retracted, the push rod 19 removes the forward squeezing effect on the sliding sleeve 14. When the push rod 19 moves backward in the top groove 18, the sliding sleeve 14 is reset outward under the elastic action of the spring 17, and the positioning rod 15 is inserted into the positioning hole 16 at the corresponding position, so that the cooperation between the positioning rod 15 and the positioning hole 16 realizes the locking and positioning of the lifting frame 3 and the transverse frame 4.

[0048] When opening the mold, during the process of retracting the lifting cylinder 6 and the transverse moving cylinder 7, the protruding ends of the lifting cylinder 6 and the transverse moving cylinder 7 will pull the elastic telescopic rod 12 backwards. After the elastic telescopic rod 12 is stretched to the longest state, the top rod 19 squeezes the rear inner wall surface of the top groove 18 backwards, causing the sliding sleeve 14 to move and squeeze the spring 17. At the same time, the positioning rod 15 is pulled out of the positioning hole 16. After that, the lifting frame 3 will move downward and the transverse moving frame 4 will move outwards to realize the mold opening operation.

[0049] In a preferred embodiment, reference Figure 6 and Figure 8 The limiting rods 21 are fixedly installed on the opposite sides of the two sliding sleeves 14. When the positioning rods 15 on the two sliding sleeves 14 are pulled out of the positioning holes 16, the opposite ends of the two limiting rods 21 are in contact.

[0050] After the positioning rods 15 on both sides of the support plate 13 are pulled out of the positioning holes 16, the two limiting rods 21 are in contact, so that the forces of the lifting cylinder 6 and the lateral displacement cylinder 7 can be more stably applied to the support plate 13 and the rack 11, thereby improving the displacement stability of the lifting frame 3 and the lateral displacement frame 4 and improving the mold clamping effect. The limiting rods 21 can also effectively prevent the spring 17 from being over-compressed, thereby extending the service life of the spring 17.

[0051] In a relatively specific embodiment, the two ends of the mounting plate 20 in the lifting and pushing structure are respectively slidably connected to the traveling frame 1; the two ends of the mounting plate 20 in the transverse pushing structure are respectively slidably connected to the lifting frame 3. The two ends of the support plate 13 in the lifting and pushing structure are respectively slidably connected to the traveling frame 1; the two ends of the support plate 13 in the transverse pushing structure are respectively slidably connected to the lifting frame 3.

[0052] Specifically, a first strip groove for displacement of the mounting plate 20 is provided on both the traveling frame 1 and the lifting frame 3 corresponding to the mounting plate 20, and the end of the mounting plate 20 is slidably provided in the first strip groove, so that the displacement direction of the mounting plate 20 is effectively guided. A second strip groove for displacement of the supporting plate 13 is provided on both the traveling frame 1 and the lifting frame 3 corresponding to the supporting plate 13, and the end of the supporting plate 13 is slidably provided in the second strip groove, so that the displacement direction of the supporting plate 13 is effectively guided.

[0053] In a preferred embodiment, reference Figure 1 The traveling frame 1 is provided with a lifting cylinder 22 for lifting the traveling frame 1 to lift the traveling wheel 2 off the ground. When adjusting the direction of the traveling wheel 2, the traveling frame 1 is first lifted by the lifting cylinder 22 to lift the traveling wheel 2 off the ground. The traveling wheel 2 can be a driving wheel with a hydraulic steering function in the prior art.

[0054] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
