Abstract
Description
Technical Field
[0001] This utility model relates to the field of bridge construction, and in particular to a synchronous control device for a steel truss girder pushing walking machine. Background Technology
[0002] Walking jacks are efficient, stable, and easy-to-operate bridge construction equipment. They achieve precise displacement of bridge beams by simulating four steps: lifting, translating, lowering, and returning. This equipment is widely used in overpass bridge construction due to its high safety, maintainability, convenience, high performance, and waterproof design. During bridge construction, multiple walking jacks can operate simultaneously, precisely coordinated and controlled by a computer control system. This system can monitor the working status of each jack in real time, including lifting, translating, and lowering movements, ensuring that all jacks operate synchronously according to a predetermined program, thereby achieving smooth and precise jacking of the beam. The main control unit (PLC) of this system is integrated into the field control cabinet, and construction personnel operate it through a touch screen.
[0003] In existing technologies, since the touch screen of the control device is generally set facing upwards, and the construction site environment is complex with a lot of dust and debris, after the operation is completed, the exposed screen may suffer from dust or scratches due to lack of protection, which may affect the touch operation. To address this, we propose an improved synchronous control device for a steel truss jacking walking machine. Utility Model Content
[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a synchronous control device for a steel truss girder pushing walking machine.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a synchronous control device for a steel truss jacking walking machine, comprising a control cabinet and a walking machine unit. The control cabinet has a display slot, and a touch screen is installed in the display slot. Protective plates are slidably installed on the upper and lower side walls of the display slot. Slots are provided on the upper and lower side walls of the display slot. Mounting slots are provided on both sides of the two protective plates. A locking block is slidably connected in the mounting slot. The locking block engages with the slot. A spring is fixedly connected between the locking block and the inner wall of the mounting slot.
[0006] As a further description of the above technical solution:
[0007] Both of the protective plates are fixedly connected to a lever on their upper surfaces, and the upper surface of the control cabinet has two sliding grooves, in which the lever is slidably disposed.
[0008] With the above technical solution, the protective plate can be moved by turning the lever, and the slide groove is used to facilitate the movement of the lever.
[0009] As a further description of the above technical solution:
[0010] The spring is movably fitted into the mounting groove, and the locking block is made of a combination of a trapezoidal block and a rectangular block.
[0011] Through the above technical solution, the part of the first card block that protrudes from the first mounting groove is a trapezoidal block structure, which makes it convenient for the first card block to slide into or out of the groove after the force is applied to the lever. The part of the first card block located in the first mounting groove is a rectangular block structure and is set to fit completely against the inner wall of the first mounting groove, so as to prevent the first card block from shaking during the sliding process.
[0012] As a further description of the above technical solution:
[0013] The protective plate is slidably fitted to the inner walls of the display slot on both sides, and the protective plate is made of stainless steel.
[0014] The above technical solutions provide sufficient impact resistance to prevent deformation and damage to the touchscreen.
[0015] As a further description of the above technical solution:
[0016] Both of the protective plates are fixedly connected to a card plate on their upper surfaces. The middle part of the outer wall of the opposite side of the two card plates is fixedly connected to a card head and a card box, respectively. The card head is movably sleeved in the card box. The card box has an installation groove two. The installation groove two has a sliding connection to a card block two. The card head has grooves on both sides. The card block two is engaged with the grooves.
[0017] By using the above technical solution, the card head can be fixed in the card box by the two card blocks engaging in the groove, thereby ensuring the docking and closure of the two card plates without applying external force and preventing the two card plates from being opened accidentally.
[0018] As a further description of the above technical solution:
[0019] A spring is fixedly connected between the second card block and the inner wall of the second mounting groove, and the spring is movably sleeved in the second mounting groove.
[0020] The above technical solution applies a force to the second card block by the second spring, causing it to engage in the groove, thereby increasing the resistance of the card head sliding out of the card box.
[0021] As a further description of the above technical solution:
[0022] There are two card blocks, and the two card blocks are respectively located on both sides of the card head.
[0023] The above technical solution improves the card holder's gripping effect on the card head.
[0024] This utility model has the following beneficial effects:
[0025] 1. Compared with the prior art, the synchronous control device for the steel truss jacking walking machine can protect the touch screen by opening a slot on the side wall of the display slot and sliding a card plate. This prevents the touch screen from being exposed to dust and debris when not in use and thus avoiding accidental touch. At the same time, the slot on the side wall of the display slot can cooperate with the card block to lock the card plate after it is opened, thus avoiding any impact on operation.
[0026] 2. Compared with the prior art, the synchronous control device for the steel truss girder pushing walking machine, by setting a clamping head and a clamping box structure between the contact surfaces of the two clamping plates respectively, can use the clamping head to engage in the clamping box to constrain the two clamping plates after they are closed, and ensure that the clamping plates protect the touch screen.

[0034] Reference Figure 1-5This utility model provides a synchronous control device for a steel truss jacking walking machine: it includes a control cabinet 1 and a walking machine unit 17. The control cabinet 1 has a display slot 2, and a touch screen 3 is installed in the display slot 2. Protective plates 4 are slidably installed on the upper and lower side walls of the display slot 2. Slots 7 are opened on the upper and lower side walls of the display slot 2. Mounting slots 9 are opened on both sides of the two protective plates 4. A locking block 10 is slidably connected in the mounting slot 9. The locking block 10 is engaged with the slot 7. A spring 11 is fixedly connected between the locking block 10 and the inner wall of the mounting slot 9. The spring 11 applies pressure to the locking block 10, so that it is engaged in the slot 7, thereby increasing the moving resistance of the protective plate 4.
[0035] Both protective plates 4 are fixedly connected to levers 5 on their upper surfaces. The upper surface of the control cabinet 1 has two sliding grooves 6. The levers 5 are slidably set in the sliding grooves 6. The protective plates 4 can be moved by moving the levers 5. The sliding grooves 6 are used to facilitate the movement of the levers 5.
[0036] Spring 11 is movably fitted inside mounting groove 9. The locking block 10 is made of two parts: a trapezoidal block and a rectangular block. The part of the locking block 10 that protrudes from the mounting groove 9 is a trapezoidal block structure, which allows the locking block 10 to slide into or out of the locking groove 7 after force is applied to the lever 5. The part of the locking block 10 that is inside the mounting groove 9 is a rectangular block structure and is set to fit completely against the inner wall of the mounting groove 9 to prevent the locking block 10 from shaking during sliding.
[0037] The protective plate 4 is slidably attached to the inner walls of the display slot 2 on both sides. The protective plate 4 is made of stainless steel plate, which provides sufficient impact resistance and avoids deformation that could affect the touch screen 3.
[0038] Both protective plates 4 are fixedly connected to the upper end face of the two plates 4. The middle part of the outer wall of the opposite side of the two plates 8 is fixedly connected to the head 12 and the box 13 respectively. The head 12 is movably sleeved in the box 13. The box 13 has a second mounting groove 14. The second mounting groove 14 is slidably connected to the second mounting groove 14. The head 12 has grooves on both sides. The second mounting groove 15 is engaged with the groove. By engaging the second mounting groove 15 in the groove, the head 12 can be fixed in the box 13. Thus, without applying external force, the two plates 8 are closed and the two plates 8 are prevented from opening accidentally.
[0039] A spring 16 is fixedly connected between the second locking block 15 and the inner wall of the second mounting groove 14. The spring 16 is movably sleeved in the second mounting groove 14. The spring 16 applies a force to the second locking block 15, causing it to engage in the groove, thereby increasing the resistance of the locking head 12 sliding out of the card box 13.
[0040] There are two card blocks 15, and the two card blocks 15 are respectively located on both sides of the card head 12 to improve the engagement effect of the card box 13 with the card head 12.
[0041] Working principle: During use, the operator moves the protective plate 4 by turning the lever 5. Due to the inclined guiding effect of the second locking block 15, after applying sufficient force, the second locking block 15 will move into the second mounting slot 14 to compress the second spring 16, thereby facilitating the disengagement of the locking head 12 from the card box 13, and opening the protective plate 4 until the first locking block 10 is inserted into the card slot 7. At this time, due to the length limitation of the slide 6, the lever 5 cannot be turned further. After releasing the lever 5, the touch screen 3 can be operated, which facilitates the control of the walking machine unit 17 to realize the construction of the bridge. After use, the lever 5 is turned again to drive the two protective plates 4 to move towards each other until the locking head 12 is reinserted into the card box 13. At this time, the two protective plates 4 can protect the touch screen 3.
[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
