Description

Technical Field

[0001] This utility model relates to the field of crane testing equipment, and in particular to a test counterweight box for debugging a container crane. Background Technology

[0002] During the final assembly, commissioning, and functional testing of container cranes (RTG, RMG, STS, ASC, etc.), it is necessary to use counterweight boxes of different standard weights for calibration of operating parameters and functional tests. Previously, standard containers were used as carriers, with items placed inside as counterweights to provide a reference for crane calibration. This method is cumbersome, requiring repeated weighing and adjustment of items to achieve the required weight, resulting in low efficiency and inconvenience for workers. Furthermore, the enclosed design of containers makes them less resistant to wind, easily swaying in winds of force 4, causing unstable data from the weight sensors and hindering successful calibration. Utility Model Content

[0003] In view of the above-mentioned defects in the prior art, the main purpose of this utility model is to overcome the shortcomings of the prior art and disclose a test counterweight box for debugging a container crane, including top and bottom keels arranged along the length of the container, vertical keels arranged along the height of the container, and horizontal keels arranged along the width of the container. The top and bottom keels, the vertical keels, and the horizontal keels are assembled to form the frame body of the container; the top of the frame body is provided with box corners.

[0004] It also includes main beams and load-bearing beams, the main beams being connected to the vertical keel, the load-bearing beams being spaced apart along the width direction of the container, and the two ends of the load-bearing beams being connected to the main beams.

[0005] Furthermore, a counterweight is placed inside the vertical keel.

[0006] Furthermore, square tubes are provided at the top, bottom and both sides of the frame body to form a truss structure.

[0007] Furthermore, the load-bearing beam is positioned near the lower end of the frame body.

[0008] Furthermore, a fork-tooth sleeve is provided on the frame body.

[0009] Furthermore, at least two more vertical keels and horizontal keels are provided between the two vertical keels and the horizontal keel of the frame body.

[0010] Furthermore, anti-collision plates are provided between the corner of the box and the top and bottom keel.

[0011] Furthermore, a sunken space is formed between the load-bearing beam and the main beam.

[0012] The beneficial effects achieved by this utility model are:

[0013] This utility model adopts a truss structure, which provides good wind protection; the side loading and unloading method for counterweights eliminates the need for forklifts and personnel to enter the container, significantly improving efficiency and personnel safety; the sunken design of the container's load-bearing beams facilitates counterweight positioning and prevents displacement, ensuring that the counterweights will not slip off the container; in addition to the corners of the standard container, the test container is equipped with forklift fork sleeves to meet the needs of unobstructed loading and unloading in the field; the position where the lifting device touches the container is reinforced by the web plate, ensuring that the test container is more robust and durable.

[0017] 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 only used to explain this utility model and are not intended to limit this utility model.

[0018] A test counterweight box for commissioning a container crane, such as Figure 1 As shown, the frame includes top and bottom supports 1 along the length of the container, vertical supports 2 along the height of the container, and horizontal supports 3 along the width of the container. The top and bottom supports 1 and the horizontal supports 3 form the upper and lower supports of the frame body. The vertical supports 2 connect the upper and lower supports, forming the frame body as a whole. A corner 7 is provided at the top of the frame body to facilitate connection and lifting with a crane. Additionally, it includes main beams 4 and load-bearing beams 5. The main beams 4 are connected to the vertical supports 2, and the load-bearing beams 5 are spaced apart along the width of the container. Both ends of the load-bearing beams 5 are connected to the main beams 4, forming a counterweight placement platform 6. The frame body has an open side structure, facilitating the placement of counterweights on the placement platform 6 using a forklift.

[0019] In one embodiment, such as Figure 1 As shown, the load-bearing beam 5 is positioned near the lower end of the frame body. This lowers the overall center of gravity of the frame body, making it more stable during hoisting.

[0020] In one embodiment, such as Figure 1As shown, a sunken space is formed between the load-bearing beam 5 and the main beam 4; that is, the upper surface of the load-bearing beam 5 is lower than the upper surface of the main beam 4. The sunken design facilitates the positioning of the counterweight and also has an anti-slip effect, thereby ensuring that the counterweight will not slip off the frame body.

[0021] In one embodiment, such as Figure 1 As shown, in order to increase the self-weight of the frame body, a counterweight is placed inside the vertical keel 2.

[0022] In one embodiment, such as Figure 1 As shown, square tubes are installed at the top, bottom, and both sides of the frame to form a truss structure. The truss structure provides excellent wind protection and increases the overall strength of the frame.

[0023] In one embodiment, such as Figure 1 As shown, a fork-tooth sleeve 7 is installed on the frame body to allow for unobstructed loading and unloading in outdoor environments.

[0024] In one embodiment, such as Figure 1 As shown, at least two more vertical keels 2 and horizontal keels 3 are provided between the two vertical keels 2 and the horizontal keel 3 of the frame body. That is, by increasing the number of vertical keels 2 and horizontal keels 3, the strength of the frame body is increased.

[0025] In one embodiment, such as Figure 1 As shown, an anti-collision web plate 8 is installed between the box corner 7 and the top and bottom keel 1.

[0026] The above are merely preferred embodiments of the present utility model and are not intended to limit the scope of implementation of the present utility model. Any modifications or equivalent substitutions to the present utility model without departing from the spirit and scope thereof should be covered within the protection scope of the claims of the present utility model.
