Technical Field

[0001] The utility model relates to the technical field of goods handling, and more specifically, particularly relates to a movable spanning frame support platform. Background Art

[0002] In the industrial field, there are various risks in the erection of traditional spanning frames. The design of traditional spanning frames is often customized for specific tasks, which limits their applicability in different applications or environments. Some spanning frames also require special operation training because their control systems are relatively complex and not easily mastered by ordinary workers quickly. Ordinary spanning frames usually occupy a large amount of horizontal and vertical space, which restricts the layout of other mechanical equipment or the effective utilization of the working area.

[0003] Moreover, the spanning frame actually contains many moving parts and mechanical systems, all of which require regular maintenance, increasing the long-term operation cost. Especially for the models using electric motors and hydraulic systems, they consume a large amount of energy during use. If not operated or maintained correctly, they will be restricted by the mechanical design, and there will be risks of tipping over or material dropping when handling heavy objects.

[0004] Therefore, there is a need for a movable spanning frame support platform with a simple structure to solve the problems of large floor area and low operation efficiency caused by regular maintenance in the prior art. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a movable spanning frame support platform to solve the problems existing in the prior art. The lifting or lowering of the movable frame is realized through the cooperation among the push arms, the movable arms and the adjusting arms, saving the floor area and improving the safety.

[0006] To achieve the above purpose, the utility model provides the following scheme: The utility model provides a movable spanning frame support platform, including: a movable frame, which is erected on the top of a support cross frame. Two adjusting parts are rotatably connected to the bottom of the movable frame. The two adjusting parts are symmetrically arranged and meshed with each other at one end. Two movable arms are slidably connected to the bottom of the support cross frame. The two movable arms are respectively hinged to the two adjusting parts; two push arms, one end of each of the two push arms is a control end, and the other end is fixedly connected to the movable arm; wherein, when the two push arms move towards the center, they drive the two movable arms to slide towards the center, and at the same time push the meshing ends of the two adjusting parts to move upwards to lift the movable frame. When the two push arms move towards both sides, they drive the two movable arms to slide towards both sides, and at the same time pull the meshing ends of the two adjusting parts to move downwards to lower the movable frame.

[0007] Further, the adjusting member includes an adjusting arm, a connecting plate and a gear. One end of the adjusting arm is hinged to the movable arm, and the other end is fixedly connected to the connecting plate. The other end of the connecting plate is fixedly connected with the gear. The two gears are meshed, and the rotating shafts of the two gears are connected to the moving frame.

[0008] Further, a groove is provided at the bottom of the moving frame, and the gear is installed in the groove.

[0009] Further, support vertical plates are further provided at the bottom of the support cross frame, and the two support vertical plates are respectively fixedly connected to both sides of the support cross frame.

[0010] Further, a workbench is provided on the moving frame for placing goods.

[0011] Further, the adjusting arm is a hydraulic rod.

[0012] The present utility model discloses the following technical effects:

[0013] In this application, by controlling the two push arms to move towards the center or move towards both sides, the movable arm and the adjusting member cooperate to move, so as to realize the lifting or lowering of the moving frame. When the two push arms move towards the center, they drive the two movable arms to move towards the center. Since the adjusting member is hinged at the bottom of the movable arm, the bottoms of the two adjusting members move towards the center, and the meshing ends at the tops of the two adjusting members move upward, thereby realizing the lifting of the moving frame. Similarly, when the two push arms move towards both sides, the meshing ends of the two adjusting members are pulled downward to lower the moving frame. The handling of goods is completed by the lifting and lowering of the moving frame. The lifting and lowering of the moving frame replace manual handling of goods, improving safety. At the same time, the structure is simple and the floor area is saved. The spanning frame in this application has a simple structure and can operate continuously. It only needs regular maintenance to ensure the continuity of production and handling operations and improve work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0020] To make the above objects, features and advantages of the present utility model more obvious and understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0021] As Figures 1 - 3 shown, the present utility model provides a movable spanning frame support platform, including a moving frame 1, the moving frame 1 is erected on the top of the supporting cross frame 2, two adjusting members are rotatably connected to the bottom of the moving frame 1, the two adjusting members are symmetrically arranged and one end of each of them meshes with the other, two movable arms 6 are slidably connected to the bottom of the supporting cross frame 2, and the two movable arms 6 are respectively hinged to the two adjusting members; two push arms 4, one end of each of the two push arms 4 is a control end, and the other end is fixedly connected to the movable arm 6.

[0022] A groove 9 is provided at the bottom of the moving frame 1, the tops of the two adjusting members mesh with each other and the tops of the two adjusting members are installed in the groove 9.

[0023] The adjusting member includes an adjustment arm 5, a connecting plate 7 and a gear 8. The bottom end of the adjustment arm 5 is hinged to the bottom of the movable arm 6 through a hinge shaft, the top end 9 of the adjustment arm 5 is fixedly connected to the bottom end of the connecting plate 7, the top end of the connecting plate 7 is fixedly connected to the gear 8, the two gears 8 mesh with each other, and the rotating shafts of the two gears 8 are installed in the groove 9, so that the gear 8 is fixed in the groove 9 and can rotate in the groove 9. In this embodiment, the adjustment arm 5 is a hydraulic rod, and the length of the adjustment arm 5 can be adjusted by extending or contracting the hydraulic rod, so as to adjust the height of the moving frame 1 lifted.

[0024] The top of the movable arm 6 is slidably connected to the supporting cross frame 2, the bottom is hinged to the adjustment arm 5, and the outer side of the bottom end is fixedly connected to the push arm 4. Among them, the push arm 4 is horizontally arranged and the movable arm 6 is vertically arranged. A sliding groove is provided at the bottom of the supporting cross frame 2, and the top end of the movable arm 6 is clamped in the sliding groove and slides along the sliding groove.

[0025] One end of the push arm 4 is the control end, which can be manually controlled. By the operator pushing the two push arms 4 towards the center of gravity or pulling the push arms 4 to move to both sides, the movement of the movable arm 6 and the adjusting arm 5 can be controlled, and thus the lifting or lowering of the mobile rack 1 can be achieved. It can also be controlled by an externally connected hydraulic cylinder. Start and adjust the hydraulic cylinder for hydraulic telescopic movement, push the push arm 4 to move, drive the movable arm 6 and the adjusting arm 5 to move, and thus control the lifting or lowering of the mobile rack 1. The other end is fixedly connected to the bottom end of the movable arm 6.

[0026] As Figure 2 shown, when manually pushing the two push arms 4 towards the center, it drives the two movable arms 6 to slide towards the center along the chute at the bottom of the support cross-frame 2, causing the bottom end of the adjusting arm 5 to move towards the center. Since the top of the adjusting arm 5 is connected with meshing gears 8 through the connecting plate 7, when the bottom end of the adjusting arm 5 moves towards the center, the two gears 8 move upward simultaneously, gradually lifting the mobile rack 1 and realizing the transportation of goods from one height position to another height position. When manually pulling the two push arms 4 to move to both sides, it drives the two movable arms 6 to slide to both sides, pulling the bottom end of the adjusting arm 5 to move to both sides, driving the meshing gears 8 to descend simultaneously, causing the mobile rack 1 to lower for reuse. During this process, the length of the adjusting arm 5 can be adjusted by the telescopic movement of the hydraulic rod, and thus the lifting height of the mobile rack 1 can be adjusted, with a wider application range.

[0027] During the handling process, the operator can precisely control the push arm 4 to achieve precise lifting and lowering of the mobile rack 1, ensuring the smooth and safe transportation of goods from one height position to another height position, minimizing the impact and shaking on the goods, optimizing the safety and efficiency of the handling process, and improving the safety during the handling process by using the mobile rack 1 to lift or lower goods instead of manual handling.

[0028] A workbench is arranged on the mobile rack 1 for fixing goods.

[0029] Support vertical plates 3 are also arranged at the bottom of the support cross-frame 2. The support vertical plates 3 are symmetrically fixed at the bottom of the support cross-frame 2 to support the entire spanning frame.

[0030] In this embodiment, the movement of the push arm 4 drives the sliding of the movable arm 6, thereby causing the top of the adjustment arm 5 to move upward or downward to achieve the lifting or lowering of the moving frame 1, completing the handling of goods. During the whole process, the dependence on manual handling is reduced, thus reducing labor costs and reducing safety accidents caused by improper human operation, and ensuring the stability and safety during the handling process. At the same time, mechanical handling is smoother than manual handling, which can reduce the damage to materials during handling. In addition, the spanning frame can operate continuously and only needs regular maintenance, which can ensure the continuity of production and handling operations. The movable spanning frame support platform reduces labor intensity and costs by improving safety, efficiency and quality. The device has a simple structure and a small occupied space.
