Description

Technical Field

[0001] This utility model relates to the field of bridge manufacturing engineering machinery, and in particular to a bridge deck unit assembly gantry with dual hydraulic cylinder synchronous drive function. Background Technology

[0002] Bridge manufacturing machinery is a type of machinery used in bridge production. Precast bridge components, such as box girders, T-beams, and cap beams, are generally heavy and difficult to operate or assemble using ordinary lifting machinery. Gantry cranes can solve the problem of lateral and longitudinal movement of these components.

[0003] In the process of realizing this application, the inventors discovered the following problems with the prior art: Most of the existing assembly gantry walking mechanisms move by means of a track motor and a slider. When assembling with high precision and when dealing with heavy parts, the matching precision between the track motor and the slider is low. During assembly, small-scale slippage is likely to occur, requiring multiple calibrations and increasing production time. At the same time, most of the existing walking mechanisms can only move laterally and do not have longitudinal movement, resulting in poor flexibility.

[0004] Therefore, those skilled in the art have provided a bridge plate unit assembly gantry with dual hydraulic cylinder synchronous drive function to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the existing technology and propose a bridge plate unit assembly gantry with dual oil cylinder synchronous drive function. Compared with the method of using a track motor and slider, the meshing method of the gear and rack of the drive mechanism is more stable and more suitable for assembly. It can also realize the up and down movement of the walking parts, which is more flexible.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a bridge plate unit assembly gantry with dual hydraulic cylinder synchronous drive function, comprising a drive mechanism and a gantry body. The drive mechanism includes two horizontal plates, two clamping blocks, a servo motor, and two clamping blocks. Two vertical plates are fixedly connected to opposite sides of the two horizontal plates near their ends. Hydraulic rods are fixedly connected inside the two clamping blocks. A rack is fixedly connected to the horizontal center line at the top of the front horizontal plate. A gear is fixedly connected to the output end of the servo motor. The gear meshes with the rack. Two moving frames are slidably connected to the outer walls of the two horizontal plates.

[0007] Furthermore, the two card blocks are fixedly connected to the inner walls on both sides of the top of the gantry body at opposite ends.

[0008] Furthermore, a synchronization controller is fixedly installed on the bottom front end of the gantry body away from the servo motor, and a control panel is fixedly installed on the bottom front end of the gantry body near the servo motor.

[0009] Furthermore, a support plate is fixedly connected to the front end of the two clamping blocks on opposite sides, and the output end of the servo motor passes through the inner wall at the center of the support plate.

[0010] Furthermore, the two clamping blocks are fixedly connected to the walking component by bolts, and the bottom of the plurality of moving frames is fixedly connected to the top of the walking component away from the center.

[0011] Furthermore, the bottom of the servo motor is fixedly connected to the top of the walking component.

[0012] Furthermore, both ends of the two horizontal plates and the opposite sides of the two vertical plates are slidably connected to the inner walls of the top two ends of the gantry body.

[0013] This utility model has the following beneficial effects: 1. This utility model proposes a bridge plate unit assembly gantry with dual hydraulic cylinder synchronous drive function. The servo motor drives the gear to rotate left through the electrical signal emitted by the control panel. The gear meshes with the rack and pinion, and moves to the left along the outer wall of the two horizontal plates through multiple moving frames, driving the traveling component to move to the left. The gear rotates right, and moves to the right along the outer wall of the two horizontal plates through multiple moving frames, driving the traveling component to move to the right. The electrical signal emitted by the control panel activates the synchronous controller, which controls the output ends of the two hydraulic rods to move synchronously up and down. The two hydraulic rods drive the two vertical plates to move up and down, and the two vertical plates further drive the two horizontal plates to move up and down. The two horizontal plates further drive the traveling component to move up and down through multiple moving frames. Compared with the method of using a track motor and a slider, the gear and rack meshing method is more stable, more suitable for assembly, and can also realize the up and down movement of the traveling component, making it more flexible.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Reference Figures 1-5 This utility model provides an embodiment of a bridge deck unit assembly gantry with dual-cylinder synchronous drive function, comprising a drive mechanism 1 and a gantry body 2. The drive mechanism 1 includes two horizontal plates 106, two locking blocks 109, a servo motor 103, and two clamping blocks 101. Two vertical plates 107 are fixedly connected to opposite sides of the two horizontal plates 106 near their ends. Hydraulic rods 105 are fixedly connected inside each of the two locking blocks 109. A rack 108 is fixedly connected to the horizontal centerline at the top of the front horizontal plate 106. A gear 104 is fixedly connected to the output end of the servo motor 103, and the gear 104 meshes with the rack 108. Two movable frames 110 are slidably connected to the outer walls of both horizontal plates 106.

[0018] Specifically, the servo motor 103 can be activated by an electrical signal emitted from the control panel 4. The servo motor 103 drives the gear 104 to rotate. Because the gear 104 meshes with the rack 108, it moves along the outer walls of the front and rear horizontal plates 106 via multiple moving frames 110 at the top, thus driving the traveling component. When the gear 104 rotates to the left, the traveling component moves to the left, and vice versa. When the servo motor 103 stops working, the output end is locked, which stops the output end from rotating. This is existing public technology and will not be described in detail here. The electrical signal emitted from the control panel 4 activates the synchronization controller 3. The electrical signal emitted by the synchronization controller 3 can cause the output ends of the two hydraulic rods 105 to rise and fall synchronously. The two vertical plates 107 move up and down, which in turn cause the two horizontal plates 106 to move up and down. The two horizontal plates 106 then move the traveling parts up and down through multiple moving frames 110. The synchronous controller 3 collects the parameters of the two hydraulic rods 105 through internal displacement sensors, encoders, and pressure sensors, calculates the deviation between the two components, and then drives the power mechanism to make adjustments. This is the general working principle of the synchronous controller 3, which should be common knowledge familiar to those skilled in the art and will not be elaborated here. The outer walls of the multiple moving frames 110 are semi-enclosed on the two horizontal plates 106, so they will not fall off. The two front moving frames 110 do not contact the rack 108.

[0019] Reference Figures 1-5 Two clamping blocks 109 are fixedly connected to the inner walls of the top two sides of the gantry body 2 at opposite ends. A synchronous controller 3 is fixedly installed on the bottom front end of the gantry body 2 away from the servo motor 103. A control panel 4 is fixedly installed on the bottom front end of the gantry body 2 near the servo motor 103. A support plate 102 is fixedly connected to the opposite front ends of two clamping blocks 101. The output end of the servo motor 103 passes through the inner wall of the center of the support plate 102. The two clamping blocks 101 are fixedly connected to the traveling component by bolts. The bottom of multiple moving frames 110 is fixedly connected to the top of the traveling component away from the center. The bottom of the servo motor 103 is fixedly connected to the top of the traveling component. The two ends of the two horizontal plates 106 and the opposite sides of the two vertical plates 107 are slidably connected to the inner walls of the top two ends of the gantry body 2.

[0020] Specifically, the two locking blocks 109 are fixed together with the gantry body 2 to provide fixation for the two hydraulic rods 105. The control panel 4 can drive the electrical work in this application. The support plate 102 provides support for the output end of the servo motor 103. The multiple moving frames 110 are made of wear-resistant steel. The two ends of the two horizontal plates 106 and the two vertical plates 107 can move up and down along the inner walls on both sides of the gantry body 2.

[0021] Working principle: When the walking component needs to move laterally, the servo motor 103 can be activated by the electrical signal emitted by the control panel 4. The servo motor 103 drives the gear 104 to rotate. The gear 104 meshes with the rack 108, which can drive the walking component to move along the outer wall of the front and rear horizontal plates 106 through the multiple moving frames 110 at the top. When the gear 104 rotates to the left, the walking component will move to the left. When the gear 104 rotates to the right, the walking component will move to the right. Secondly, the electrical signal emitted by the control panel 4 enables the synchronous controller 3 to work. The electrical signal emitted by the synchronous controller 3 enables the output ends of the two hydraulic rods 105 to move up and down synchronously. The two hydraulic rods 105 drive the two vertical plates 107 to move up and down. The two vertical plates 107 then drive the two horizontal plates 106 to move up and down. The two horizontal plates 106 move the walking components up and down through multiple moving frames 110.

[0022] 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.
