Description

Technical Field

[0001] This utility model belongs to the technical field of semiconductor testing industry, and in particular relates to a mobile vehicle. Background Technology

[0002] The positioning and installation of equipment cannot be separated from the base. Symmetrically distributed bases can more stably and reliably install the equipment in the appropriate position.

[0003] To facilitate movement, equipment is usually equipped with appropriately sized wheels, typically omnidirectional wheels. However, once the weight of the equipment reaches the limit that the wheels can bear, moving the equipment becomes very difficult. For the safety of the equipment and personnel, the test head and counterweight are usually removed, and the original equipment is moved separately. This process consumes a lot of manpower and time.

[0004] During equipment relocation, the confined space makes it difficult to apply force, and the support rollers are not aligned. Solution one is to raise all the equipment's base feet and rotate the support rollers to align all the rollers in the same direction before moving. Solution two requires brute force to forcibly push the support rollers together, which would damage both the support rollers and the static grounding. Utility Model Content

[0005] The purpose of this utility model is to provide a mobile trolley to solve the above-mentioned technical problems.

[0006] To achieve the above objectives, the specific technical solution of this utility model for a mobile trolley is as follows:

[0007] A mobile trolley includes a base frame, a first connecting rod, a second connecting rod, a middle hinge rod, an upper end plate, a first slide rail, a first roller, a middle connecting block, a drive screw, a first actuator motor, a bracket, a drive roller, a second roller, a second slide rail, and a middle screw. The base frame is hinged to one end of the first connecting rod, and the second roller is rotatably mounted on the other end of the first connecting rod. The second roller is in rolling contact with the second slide rail. The second slide rail is fixedly mounted on the upper end plate, and the upper end plate is hinged to one end of the second connecting rod. The first roller is rotatably mounted on the other end of the second connecting rod, and the first roller is in rolling contact with the first slide rail. The first slide rail is fixedly mounted on the base frame, and the first actuator motor is mounted on the base frame. The drive screw is rotatably mounted on the base frame and connected to the output shaft of the first actuator motor. A middle connecting block is threaded onto the drive screw. The first connecting rod and the second connecting rod are hinged together by the middle hinge rod.

[0008] An extended support assembly is installed on the base frame, and the middle connecting block is rotatably connected to the roller.

[0009] Furthermore, the extended support assembly includes a support column, a slide, a mounting sleeve, an end cap, a second actuator motor, a drive screw, a first bevel gear, a second bevel gear, and a third actuator motor. The mounting sleeve is fixedly mounted on the slide, the end cap is mounted on the mounting sleeve, and the second actuator motor is mounted on the end cap. The output shaft of the second actuator motor is mounted on the drive screw, which is rotatably mounted on the end cap. The drive screw is threadedly connected to the support column. The support column is slidably mounted inside the mounting sleeve. The slide is slidably mounted on a base frame, and the third actuator motor is mounted on the base frame. The second bevel gear is mounted on the output shaft of the third actuator motor, and the second bevel gear meshes with the first bevel gear. The first bevel gear is fixedly mounted on the drive screw, which is rotatably mounted on the base frame. The drive screw is threadedly connected to the slide.

[0010] Furthermore, a rectangular groove A is formed on the inner wall of the mounting sleeve, and a rectangular protrusion A is provided on the support column. The rectangular protrusion A and the rectangular groove A are slidably limited together.

[0011] Furthermore, a bracket is mounted on the base frame, and a drive roller is rotatably mounted on the bracket.

[0012] The advantages of this utility model are:

[0013] 1. Start the first actuator motor. The first actuator motor drives the drive screw to rotate. The drive screw drives the middle connecting block to move. Through the middle connecting block, the first roller moves along the first slide rail, and the first and second connecting rods rotate relative to the middle hinge rod, so that the distance between the upper plate and the base frame changes, thereby adjusting the height of the upper plate.

[0014] 2. When it is necessary to extend the support carriage, start the third actuator. The third actuator, through the meshing transmission between the second and first bevel gears, drives the drive screw to rotate, causing the carriage to slide along the base frame, thereby changing the support position of the support column on the device. At the same time, start the second actuator and drive the drive screw to rotate. Through the threaded connection between the drive screw and the support column, the support column slides along the mounting sleeve and contacts the ground, causing the support column to support the entire device in the opposite direction. At the same time, the flatness of the base frame and the entire device can be adjusted according to the extension degree of the support column at different positions. Attached Figure Description

[0025] Example 1

[0026] like Figure 1-7As shown, a mobile trolley includes a base frame 1, a first connecting rod 2, a second connecting rod 3, a middle hinged rod 4, an upper end plate 5, a first slide rail 6, a first roller 7, a middle connecting block 8, a drive screw 9, an actuator motor 10, a bracket 11, a drive roller 12, a second roller 22, a second slide rail 23, and a middle screw 24. The base frame 1 is hinged to one end of the first connecting rod 2, and the other end of the first connecting rod 2 is rotatably mounted with the second roller 22. The second roller 22 rolls in contact with the second slide rail 23, and the second slide rail 23 is fixedly installed. On the upper end plate 5, the upper end plate 5 is hinged to one end of the connecting rod 2 3, and the other end of the connecting rod 2 3 is rotatably mounted with a roller 7, and the roller 7 rolls in contact with the slide rail 6. The slide rail 6 is fixedly mounted on the base frame 1, and an actuator motor 10 is mounted on the base frame 1. A drive screw 9 is rotatably mounted on the base frame 1, and the drive screw 9 is connected to the output shaft of the actuator motor 10. A middle connecting block 8 is threaded on the drive screw 9. The connecting rod 2 and the connecting rod 2 3 are hinged together by the middle hinge rod 4.

[0027] An extended support assembly is installed on the base frame 1. The middle connecting block 8 is rotatably connected to the roller 7. With this configuration, when the actuator motor 10 is started, the actuator motor 10 drives the drive screw 9 to rotate. The drive screw 9 drives the middle connecting block 8 to move. Through the middle connecting block 8, the roller 7 moves along the slide rail 6, and the connecting rod 2 and connecting rod 3 rotate relative to the middle hinge rod 4. This causes the distance between the upper plate 5 and the base frame 1 to change, thereby adjusting the height of the upper plate 5.

[0028] Example 2

[0029] like Figure 1-7As shown, the extended support assembly includes a support column 13, a slide 14, a mounting sleeve 15, an end cap 16, a second actuator 17, a drive screw 18, a first bevel gear 19, a second bevel gear 20, and a third actuator 21. The mounting sleeve 15 is fixedly mounted on the slide 14, the end cap 16 is mounted on the mounting sleeve 15, and the second actuator 17 is mounted on the end cap 16. The output shaft of the second actuator 17 is mounted on the drive screw 18, which is rotatably mounted on the end cap 16. The drive screw 18 is threadedly connected to the support column 13. The support column 13 is slidably mounted inside the mounting sleeve 15. The slide 14 is slidably mounted on the base frame 1, and the third actuator 21 is mounted on the base frame 1. The second bevel gear 20 is mounted on the output shaft of the third actuator 21, and the second bevel gear 20 meshes with the first bevel gear 19. The first bevel gear 19 is fixedly mounted on the drive screw. On rod 18, drive screw 18 is rotatably mounted on base frame 1. Drive screw 18 is threadedly connected to slide 14. With this configuration, when it is necessary to extend the support slide 14, actuator motor 3 21 is activated. Actuator motor 3 21 drives drive screw 18 to rotate through the meshing transmission between bevel gear 20 and bevel gear 19, driving slide 14 to slide along base frame 1, thereby changing the support position of support column 13 on the device. At the same time, actuator motor 2 17 is activated and drives drive screw 18 to rotate. Through the threaded connection between drive screw 18 and support column 13, support column 13 slides along mounting sleeve 15 and contacts the ground, so that support column 13 supports the entire device in the opposite direction. At the same time, the flatness of base frame 1 and the entire device can be adjusted according to the extension degree of support column 13 at different positions.

[0030] The mounting sleeve 15 has a rectangular groove A on its inner wall, and the support column 13 has a rectangular protrusion A, which slides and limits the movement of the rectangular protrusion A with the rectangular groove A.

[0031] Example 3

[0032] like Figure 1-7 As shown, a bracket 11 is mounted on the base frame 1, and a drive roller 12 is rotatably mounted on the bracket 11.
