Description

Technical Field

[0001] This utility model belongs to the field of bottom mold trolleys, specifically relating to a frame structure of a bottom mold trolley. Background Technology

[0002] Currently, segmental bridges are mostly constructed using the short-line method, and the bottom formwork trolley is a key piece of equipment for the prefabrication of box girder segments. It is used to adjust the matching beam segments to the preset position, which has a great impact on the segment quality and production efficiency.

[0003] The existing bottom mold trolley adopts a multi-layer design, that is, the bottom layer of the bottom mold trolley is the drive unit, the platform is supported above the drive unit, the adjustment components are supported above the platform, and the control box and other equipment are mounted on the side of the platform. Since the drive unit is located directly below the platform, the drive unit restricts the installation space of the adjustment components, making the installation of the adjustment components cumbersome. At the same time, the platform often uses the method of welding support bars on the side to hang the control box, which makes the bottom of the control box lack effective support. Utility Model Content

[0004] Therefore, this utility model provides a frame structure for a bottom mold trolley to solve the problem that existing bottom mold trolleys are difficult to install adjustment components.

[0005] A frame structure for a bottom mold trolley includes a platform, a drive unit connected to the side of the platform, and a connector fixed in the middle of the platform. The connector is used to connect an adjustment device, which is used to adjust the posture of the moving platform of the bottom mold trolley.

[0006] Furthermore, the drive unit is provided in two sets, and the two sets of drive units are respectively located on opposite sides of the platform.

[0007] Furthermore, the drive unit includes a roller frame with a roller disposed in the middle of the roller frame, and a motor for driving the roller is fixed to the side of the roller frame.

[0008] Furthermore, each roller corresponds to a motor.

[0009] Furthermore, an electrical control cabinet is fixedly connected to the top of the drive unit.

[0010] Furthermore, a bracket is fixedly connected to the top of the drive unit, and a cable reel is mounted on the bracket.

[0011] Furthermore, the platform is hollow, including connecting beams at both ends and a main frame in the middle, with connecting plates installed on the sides and / or top of the main frame.

[0012] Furthermore, the main frame includes three connecting rods that form a triangle, and several connecting plates are installed on the outer side of the triangle.

[0013] Furthermore, at least three support legs are installed on the bottom side of the platform, and the support legs are also connected to linear actuators that drive them to move up and down.

[0014] Beneficial effects: By placing the drive unit on the side of the platform, this utility model leaves space on both the top and bottom sides of the platform, thereby reducing the difficulty of installing the adjustment components. Attached Figure Description

[0015] To make the content of this utility model easier to understand, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0020] 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. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.

[0021] Example 1

[0022] like Figure 1-2 As shown, this embodiment provides a frame structure for a bottom mold trolley, including a platform 1. A drive unit 2 is connected to the side of the platform 1, and a connector 3 is fixed in the middle of the platform 1. The connector 3 is used to connect an adjustment device (not shown in the figure), and the top of the adjustment device is connected to a moving platform.

[0023] (Not shown in the figure) The adjustment device is used to adjust the posture of the moving platform of the bottom mold trolley. In this embodiment, the drive unit 2 and the platform 1 are arranged in parallel, so that the bottom of the platform 1 is left with space to facilitate the installation and operation of the adjustment components.

[0024] Specifically, in this embodiment, there are two sets of drive units 2, which are respectively set on both sides of the platform 1. The two sets of drive units are arranged opposite each other to ensure that the trolley frame is balanced by force. The drive unit includes two roller frames 21, which are respectively set at the corners near the platform. A roller 22 is set in the middle of the roller frame 21. A motor 23 that drives the roller 22 is fixed on the side of the roller frame 21. In order to protect the motor 23, the two motors are arranged facing each other between the two roller frames 21.

[0025] To improve the mobility and braking effect of the drive unit 2, each roller 22 is paired with a motor 23, so that each roller 22 is driven by a motor. Compared with the existing method of using a combination of active and passive rollers for driving, the drive capability of the fully active rollers is stronger. The braking of each roller is controlled by the motor, so the braking effect is better than that of the passive rollers.

[0026] The top of the drive unit 2 is fixedly connected to the electrical control cabinet 4, so that the drive unit 2 can support the platform 1 and the electrical control cabinet 4 at the same time, which is more stable than the existing method of supporting by installing support bars on the side.

[0027] The top of the drive unit 2 is also fixedly connected to a bracket 5, on which a cable reel 51 is installed. Since the bottom formwork trolley moves during the actual bridge casting process, the cable reel 51 on the top of the drive unit 2 can effectively store the wires and prevent them from falling into the track and causing safety risks.

[0028] like Figure 1 As shown, the platform 1 is hollow. The platform 1 specifically includes connecting beams 11 at both ends and a main frame 12 in the middle. Connecting parts 3 are installed on the side of the main frame 12. Since the drive unit is set on the side of the platform 1, the bottom of the platform 1 is empty space. Therefore, the connecting parts 3 are installed on the side of the main frame 12 to install rotating mechanisms such as Hooke's joints, and the assembly will not be affected by the width of the rotating mechanism.

[0029] The main frame 12 includes three connecting rods that form a triangle, and several connectors 3 are installed on the outer side of the triangle. Alternatively, the main frame 12 can also be formed by four connecting rods that form a quadrilateral, and reinforced connectors can be provided to connect the opposite corners to improve the structural strength, and these connectors can be provided on the four sides of the quadrilateral.

[0030] In this embodiment, four support legs 6 are installed on the bottom side of the platform. The support legs 6 are specifically located at the ends of two connecting crossbeams and are also connected to linear actuators 7 that drive them to move up and down. The linear actuators 7 are specifically screw lifts, but electric cylinders or hydraulic cylinders can also be used instead. After the bottom mold trolley moves to the preset position, the linear actuators 7 extend the support legs 6 to replace the drive unit 2 in supporting the platform 1.
