Description

Technical Field

[0001] This utility model relates to the field of road and bridge construction technology, and in particular to a self-propelled hydraulic T-beam prefabrication device. Background Technology

[0002] A T-beam is a beam with a T-shaped cross-section. The cantilevered portions on both sides are called flanges, and the middle portion is called a beam rib (or web). Since it is essentially formed by removing the tension zone concrete that does not contribute to the bending strength of a rectangular beam, it has the same bending strength as the original rectangular beam, but saves concrete, reduces the self-weight of the component, and improves the spanning capacity. It is one of the main components of viaduct construction.

[0003] However, T-beams are prefabricated and then spliced ​​together. During prefabrication, the reinforcing bars are placed in the T-beam mold for casting. However, due to the structural characteristics of T-beams, the T-beam molds need to be assembled one by one during construction and disassembled one by one after casting. This cumbersome assembly and disassembly process results in low manufacturing efficiency of T-beams.

[0004] Therefore, it is necessary to provide a new self-propelled hydraulic T-beam prefabrication device to solve the above-mentioned technical problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a self-propelled hydraulic T-beam prefabrication device that allows for rapid casting and demolding, saving time and labor during construction.

[0009] Several self-propelled frames are provided, and these frames are slidably mounted on two sets of guide rails. Each self-propelled frame is equipped with a drive component for driving movement. A second hydraulic cylinder is mounted on each self-propelled frame, and a sliding seat is fixedly mounted on the telescopic end of the second hydraulic cylinder. The sliding seat slides in cooperation with the self-propelled frame. Two sets of third hydraulic cylinders are symmetrically mounted on the top of the sliding seat. The telescopic ends of the third hydraulic cylinders located on the same side of the boss are jointly fixedly mounted on a support beam. A side mold frame is fixedly mounted on the support beam, and a side template is mounted on the side mold frame.

[0010] Preferably, four hydraulic cylinders are symmetrically installed on the end template, and a pull rod is threaded onto the telescopic end of the four hydraulic cylinders.

[0011] Preferably, the casting surfaces of the bottom template, end template, and side template are all made of stainless steel.

[0012] Preferably, the driving component includes a power motor and a reducer, both of which are fixedly mounted on the self-propelled frame. The output shaft of the power motor is coaxially and fixedly connected to the input shaft of the reducer, and the output shaft of the reducer is fixedly fitted with a traveling wheel that contacts the foundation.

Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0026] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0027] Please see Figures 1 to 5 This utility model provides a self-propelled hydraulic T-beam prefabrication device, which includes:

[0028] The foundation 1, and the boss 11 provided on the foundation 1, and two sets of guide rails 12 are symmetrically installed on both sides of the boss 11 on the foundation 1.

[0029] The bottom mold frame 2 is fixedly installed on the upper surface of the boss 11, and the bottom template 21 is fixedly installed on the upper surface of the bottom mold frame 2. Hydraulic cylinders 3 are fixedly installed at both ends of the bottom mold frame 2, and end templates 31 are fixedly installed at the telescopic ends of the hydraulic cylinders 3.

[0030] Several self-propelled frames 4 are provided, and the self-propelled frames 4 are slidably installed on two sets of guide rails 12. Each self-propelled frame 4 is provided with a drive component 5 for driving movement. A hydraulic cylinder 6 is installed on the self-propelled frame 4. The telescopic end of the hydraulic cylinder 6 is fixedly installed with a sliding seat 61. The sliding seat 61 is slidably engaged with the self-propelled frame 4. Two sets of hydraulic cylinders 62 are symmetrically installed on the top of the sliding seat 61. The telescopic ends of the hydraulic cylinders 62 located on the same side of the boss 11 are jointly fixedly installed with a support beam 63. A side mold frame 64 is fixedly installed on the support beam 63. A side template 65 is installed on the side mold frame 64.

[0031] It should be noted that during use, the steel cage used to make the T-beam is placed on the bottom formwork 21. The hydraulic cylinder 3 is driven to extend and retract, driving the end formwork 31 to clamp the steel cage onto the bottom formwork 21. Then, the self-propelled frame 4 is driven by the drive component 5 to move along the guide rail 12 until the side formwork 64 on both sides of the boss 11 is moved to both sides of the steel cage. Then, the hydraulic cylinder 6 is controlled to drive the sliding seat 61 to slide along the self-propelled frame 4, driving the side formwork 65 to approach the bottom formwork 21. After it is close and tightly attached, the hydraulic cylinder 62 is controlled to adjust the height of the side formwork 64 so that it is aligned and in place, thus completing the mold closing. Concrete can then be poured into the pouring cavity formed by the end formwork 31 and the side formwork 65. After the pouring and curing are completed, the hydraulic cylinder 3 is controlled to extend, driving the end formwork 31 to separate. Then, the hydraulic cylinder 6 is controlled to retract, driving the side formwork 65 to separate, thus automatically realizing the demolding. The entire assembly and demolding process is very convenient, greatly improving the precast pouring speed of the T-beam.

[0032] The casting surfaces of the bottom template 21, end template 31, and side template 65 are all made of stainless steel, which prevents rust and adhesion during use, improves the service life of the mold, and facilitates demolding later.

[0033] The side template 65 is symmetrically provided with reinforcing rib grooves 601. The reinforcing rib grooves 601 are narrow on the outside and wide on the inside. This arrangement of reinforcing rib grooves 601 improves the support strength of the T-beam, and the narrow on the outside and wide on the inside shape of the reinforcing rib grooves 601 facilitates the demolding of the side template 65.

[0034] In the embodiments of this utility model, please refer to Figures 1 to 5 Hydraulic cylinders 32 are symmetrically installed on the end template 31, and a pull rod 33 is threadedly installed on the telescopic end of the hydraulic cylinders 32.

[0035] It should be noted that after the hydraulic cylinder 3 drives the end template 31 to close the mold, the hydraulic cylinder 4 32 is then controlled to extend into the side mold frame 64 of the mold closing mechanism. Then, the pull rod 33 is turned to make it lock with the side mold frame 64. Then, the hydraulic cylinder 4 32 is controlled to retract until the pull rod 33 pulls the end template 31 against one side of the side template 65, thereby improving the tightness of the mold closing.

[0036] In the embodiments of this utility model, please refer to Figures 1 to 5 The driving component 5 includes a power motor 51 and a reducer 52. The power motor 51 and the reducer 52 are both fixedly installed on the self-propelled frame 4. The output shaft of the power motor 51 is coaxially and fixedly connected to the input shaft of the reducer 52. The output shaft of the reducer 52 is fixedly sleeved with a traveling wheel 53 that contacts the foundation 1.

[0037] It should be noted that when the drive component 5 is in use, by controlling the rotation of the power motor 51, the reducer 52 reduces the speed and drives the walking wheel 53 to roll along the foundation 1, and drives the self-propelled frame 4 to slide along the guide rail 12 to achieve automatic walking, which facilitates mold closing and disassembly.

[0038] In the embodiments of this utility model, please refer to Figures 1 to 5 The side mold frame 64 is equipped with a plurality of auxiliary supports 66, and the bottom end of the auxiliary support 66 is threaded with a support rod 661, and the bottom end of the support rod 661 is fixedly equipped with a pad 662.

[0039] It should be noted that, in order to improve the support strength of the side mold frame 64 during mold closing, the support rod 661 is turned until the pad block 662 contacts the foundation 1, thereby providing auxiliary support for the entire side mold frame 64, making the mold closing more compact and stable, and facilitating the improvement of the overall T-beam casting quality.

[0040] In this embodiment, the top of the side formwork frame 64 is installed on the corridor frame 67, which makes it convenient for the operator to stand on the corridor frame 67 to carry out the pouring operation during the pouring process.

[0041] The working principle of the self-propelled hydraulic T-beam prefabrication device provided by this utility model is as follows:

[0042] In use, the steel cage for making the T-beam is placed on the bottom formwork 21. Hydraulic cylinder 3 extends and retracts, driving end formwork 31 to clamp the steel cage onto the bottom formwork 21. The power motor 51 rotates, and the reducer 52 slows the rotation, causing the traveling wheels 53 to roll along the foundation 1, driving the self-propelled frame 4 to slide along the guide rail 12. The self-propelled frame 4 moves along the guide rail 12 until the side formwork frames 64 on both sides of the boss 11 are moved to the sides of the steel cage. Then, hydraulic cylinder 6 drives the sliding seat 61 to slide along the self-propelled frame 4, driving the side formwork 65 closer to the bottom formwork 21. Once close and tightly fitted, hydraulic cylinder 62 adjusts the height of the side formwork frames 64 to ensure proper alignment, thus completing the formwork closure. After the mold is closed, control hydraulic cylinder 32 to extend into the side mold frame 64 of the mold closure, then turn the pull rod 33 to make it lock with the side mold frame 64, then control hydraulic cylinder 32 to retract until the pull rod 33 pulls the end template 31 against one side of the side template 65, improving the tightness of the mold closure, and then pour concrete into the pouring cavity composed of the bottom template 21, end template 31 and side template 65. After pouring and curing, turn the pull rod 33 to release the lock restriction, then control hydraulic cylinder 3 to extend, driving the end template 31 to separate the mold, then control hydraulic cylinder 6 to retract, driving the side template 65 to separate the mold, thus automatically realizing the demolding. The whole assembly and demolding is very convenient, greatly improving the precast pouring processing speed of T-beams;

[0043] Furthermore, during mold closing, in order to improve the support strength of the side mold frame 64, the support rod 661 is twisted until the pad block 662 contacts the foundation 1, thereby providing auxiliary support for the entire side mold frame 64, making the mold closing more compact and stable, and facilitating the improvement of the overall T-beam casting quality.

[0044] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.

[0045] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
