Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. The embodiments of this utility model will be described below based on its overall structure.

[0024] Reference Figures 1 to 7In this embodiment of the utility model, a practical examination and scoring device for crane operators includes: a base body 1, a motor housing 2 fixedly connected to one outer end of the base body 1, a lead screw 3 rotatably connected to one inner end of the base body 1, a supporting sliding base 4 slidably connected to the other inner end of the base body 1, an examination and scoring host 5 fixedly connected to the top of the supporting sliding base 4 by bolts, a display screen 6 electrically connected to the top of the examination and scoring host 5, a stepping board 7 fixedly connected to one upper end of the base body 1, an operating housing 8 fixedly connected to the other outer end of the base body 1, and a seat 9 fixedly connected to the other outer end of the base body 1. The interior of the 7th unit has a storage slot 10, and a folding plate 11 is fixedly connected inside the storage slot 10. A roller 12 is rotatably connected to one end of the bottom of the supporting sliding base 4. The examination scoring host 5 and the operating box 8 are connected by wires. The other end of the folding plate 11 is fixedly connected to the supporting sliding base 4 by bolts. The lead screw 3 is threadedly connected to the supporting sliding base 4. The other end of the lead screw 3 passes through the base body 1. The motor box 2 integrates a motor and gear transmission components and is connected to the other end of the lead screw 3. The two sides of the base body 1 are provided with sliding grooves for the sliding of the supporting sliding base 4. The bottom of the base body 1 is provided with a rolling groove for the roller 12 to roll.

[0025] The above scheme is adopted: the base body 1 serves as the basic support for the entire device. At one end of the base body 1, a motor housing 2 is fixedly connected, integrating a motor and gear transmission components to drive subsequent mechanical movements. A lead screw 3 is rotatably connected to one end of the inner side of the base body 1, while a supporting sliding base 4 is slidably connected to the other end. A test scoring host 5 is bolted to the top of this supporting sliding base 4 for scoring practical examinations. A display screen 6 is electrically connected to the top of the test scoring host 5 to display scoring results or other relevant information. At the upper end of the base body 1, a footrest 7 is fixedly connected. This is a long strip plate fixedly connected to the top of the base body 1, its main purpose being to provide trainees with a comfortable footrest area, allowing them to free their legs during practical examinations and simulate the standing posture during crane operation. The footrest 7 also has a storage slot 10 inside for storing a folding plate 11. The other end of 11 is fixedly connected to the supporting sliding base 4 by bolts, and can extend and retract with the movement of the supporting sliding base 4. When the supporting sliding base 4 slides inside the base body 1, the folding plate 11 will unfold or retract accordingly. Its main purpose is to cover part of the base body 1 to prevent students from seeing unnecessary mechanical structures or wire connections during the exam, and to prevent debris from falling into the base body 1, thereby maintaining the focus and safety of the exam. The design of the folding plate 11 not only improves the neatness of the device, but also ensures that the student's vision is not disturbed during the exam. In terms of mechanical action, the motor and gear transmission assembly inside the motor box 2 are connected to the other end of the lead screw 3. By driving the rotation of the lead screw 3, the supporting sliding base 4 can be driven to slide inside the base body 1. At the same time, a roller 12 is also rotatably connected to one end of the bottom of the supporting sliding base 4, which can roll in the groove opened inside the base body 1 to further assist the sliding action.

[0026] Reference Figure 1 , Figure 6 and Figure 7 The top of the operating chassis 8 is provided with an icon fixing mechanism 13. The icon fixing mechanism 13 includes a box 1301, a base block 1302 and a magnetic block 1303. The base block 1302 is fixedly connected to the bottom of the box 1301, and the magnetic block 1303 is fixedly connected to the bottom of the base block 1302. There is also a block 1304 and a filling groove 1305. The block 1304 is inserted into the inside of the box 1301, and the filling groove 1305 starts from the top of the block 1304. There are multiple sets of icon fixing mechanisms 13, which are symmetrically arranged on the top of the operating chassis 8.

[0027] The above solution is adopted: The icon fixing mechanism 13 on the top of the control box 8 is used to fix the relevant operation icons or safety indicators. This icon fixing mechanism 13 includes a box 1301, a base block 1302, a magnetic block 1303, a plug 1304, and a glue filling groove 1305. According to the specific size of the operation icon or safety indicator, the box 1301 can be adjusted and placed by the base block 1302 and the magnetic block 1303 at its bottom. Then, the glue filling groove 1305 on the plug 1304 is filled with glue, and then the operation icon or safety indicator can be pasted on.

[0028] Reference Figure 1 and Figure 2 A guardrail 14 is fixedly connected to one end of the top of the stepping board 7, and an operating lever 15 is provided at the other end of the top of the operating box 8.

[0029] Using the above scheme: the examinee operates the control box 8 through the control lever 15. The operation data is transmitted to the examination scoring host 5 through the wire for processing and scoring. A guardrail 14 is also fixedly connected to the top end of the step board 7 to ensure the safety of the examinee. It also serves to indicate the edge of the step board 7. It clearly marks the area where the examinee can stand and operate, which helps the examinee maintain the correct posture and position, so as to more accurately perform the examination requirements.

[0030] The working principle of this utility model is as follows: In use, the motor box 2 drives the gear transmission assembly and drives the lead screw 3 to rotate. The rotation of the lead screw 3 causes the supporting sliding base 4 to slide inside the base body 1. The sliding of the supporting sliding base 4 not only adjusts the position of the examination scoring host 5, but also drives the folding plate 11 to unfold or retract. The examinee operates on the operating box 8 through the operating lever 15. The operation data is transmitted to the examination scoring host 5 through the wire for processing and scoring. The scoring results are displayed on the display screen 6 for the examinee and invigilator to view. By adjusting the position of multiple sets of insertion boxes 1301, and then applying adhesive to the insertion block 1304 and inserting it into the insertion box 1301, it can accommodate operation icons or safety indicators of different sizes and shapes, and avoids directly fixing the operation icons or safety indicators to the equipment, which is very inconvenient for subsequent replacement or cleaning.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
