Detailed Implementation

[0020] 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. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the scope of the present utility model.

[0021] See Figures 1-3 This utility model provides a small-scale machine tool moving device in a field, comprising:

[0022] The vehicle body 1 has two wheels 11 symmetrically rotatably connected to one end. The user installs a drive mechanism (such as a motor) on the vehicle body 1 that cooperates with the wheels 11 to automatically rotate the wheels 11, thus saving manpower. The direction and speed of the drive mechanism can be controlled by the user; this is existing technology and will not be described further. A downward-facing bent plate 13 is fixedly connected to the end of the vehicle body 1 away from the wheels 11. Several auxiliary supports 12 are fixedly connected to the side of the bent plate 13 closest to the vehicle body 1. When the vehicle body 1 is in a horizontal state, the bottom of the auxiliary supports 12 is horizontally higher than the bottom of the wheels 11. A handle plate 15 is rotatably connected to the top surface of the end of the vehicle body 1 closest to the wheels 11. A handle ring 16 is fixedly connected to the end of the handle plate 15 away from the vehicle body 1. A torsion spring is provided at the connection between the handle plate 15 and the vehicle body 1. When the torsion spring is in its natural state, the handle plate 15 is in a horizontal state.

[0023] The lifting guide rail 2 is fixedly mounted on the top surface of the bent plate 13 at the end away from the wheel 11. The lifting guide rail 2 is provided with a through groove, and several fixed shafts 21 are fixedly connected in the through groove. The lifting seat 22 is slidably mounted in the through groove, and all the fixed shafts 21 pass through the lifting seat 22. The side wall of the lifting seat 22 away from the vehicle body 1 is fixedly connected with a buckle 23. The buckle 23 can be stably connected to the machine and can also be disengaged from the machine. The buckle 23 is a relatively mature existing technology, so it will not be described in detail in this utility model.

[0024] The brake plate 3 is located on the side of the vehicle body 1 away from the lifting guide rail 2 on the handle plate 15. The brake plate 3 is mounted on several limiting shafts 31. The bottom ends of the limiting shafts 31 are fixedly connected to the vehicle body 1, and the top ends of the limiting shafts 31 are fixedly connected to the limiting plates. A first spring is provided between the limiting plates and the brake plate 3. The two ends of the first spring are fixedly connected to the limiting plates and the brake plate 3, respectively. Both ends of the brake plate 3 are fixedly connected to brake blocks 33 that can cooperate with the wheels 11. The brake blocks 33 have rough surfaces that cooperate with the wheels 11. When the first spring is in its natural state, the brake blocks 33 do not cooperate with the wheels 11. At this time, the user can pull the vehicle body 1 forward by pulling the handle ring 16. When no one operates the handle plate 15, the handle plate 15 presses down on the brake plate 3 under the action of the torsion spring, causing the brake blocks 33 to squeeze the wheels 11, thereby achieving automatic parking and improving the safety of the device.

[0025] The pedal 4 is rotatably located at the end of the vehicle body 1 away from the lifting guide rail 2. A driven shaft 6 is rotatably located on the side of the vehicle body 1 near the lifting guide rail 2. Both ends of the driven shaft 6 are rotatably connected to support plates, which are fixedly connected to the bottom surface of the vehicle body 1. A gear 52 is fixedly connected to the end of the driven shaft 6 near the pedal 4. A drive seat 5 is located below the gear 52. A rack 52 that can mesh with the gear 52 is fixedly connected to the top surface of the drive seat 5. The drive seat 5 slides through several guide shafts 51. All guide shafts 51 are fixedly connected to the bottom surface of the vehicle body 1. Each guide shaft 51 has a limiting member at its bottom end. Several second springs are provided between the drive seat 5 and the bottom surface of the vehicle body 1. The two ends of the second springs are fixedly connected to the vehicle body 1 and the drive seat 5, respectively. When the second spring is in its natural state, the rack 52 meshes with the gear 61. A number of drive linkages 41 are rotatably provided between the pedal 4 and the drive seat 5. One end of the drive linkage 41 is rotatably connected to the pedal 4, and the other end of the drive linkage 41 is rotatably connected to the drive seat 5. When the pedal 4 is pressed, the pedal 4 rotates with its connection point with the vehicle body 1 as the center. Under the action of the drive linkages 41, the drive seat 5 is driven to move downward along the guide shaft 51.

[0026] The drive sleeve 7 is rotatably sleeved outside the driven shaft 6. The drive sleeve 7 is located on the side of the drive seat 5 near the lifting guide rail 2. The drive sleeve 7 is equipped with a drive seat 8, which is slidably connected to the bottom surface of the vehicle body 1. The surface of the drive sleeve 7 has a guide groove that mates with the drive seat 8. The guide groove includes a straight section and a spiral section that are connected to each other. A guide post that mates with the guide groove is fixedly connected to the drive seat 8. A mating link 81 is rotatably connected between the drive seat 8 and the drive seat 5. That is, one end of the mating link 81 is rotatably connected to the drive seat 8, and the other end of the mating link 81 is rotatably connected to the drive seat 5. A disc 71 is fixedly connected to one end of the drive sleeve 7. A ratchet 72 is fixedly mounted on the disc 71. The ratchet 72, the disc 71, the drive sleeve 7, and the driven shaft 6 are concentric. A unidirectional rotatable pawl 63 is rotatably connected to the driven shaft 6. When the ratchet 72 and the pawl 63 are engaged, the drive sleeve 7 can drive the driven shaft 6 to rotate unidirectionally. A driven seat 62 is provided at one end of the driven shaft 6 near the lifting guide rail 2. The driven seat 62 is slidably connected to the vehicle body 1. The driven shaft 6 is provided with a reciprocating groove that cooperates with the driven seat 62 (the cooperation method between the driven shaft 6 and the driven seat 62 is the same as that of the reciprocating lead screw). A connecting belt 9 is provided between the driven seat 62 and the lifting seat 22. The two ends of the connecting belt 9 are fixedly connected to the driven seat 62 and the lifting seat 22 respectively.

[0027] See Figures 1-3 Preferably, the top of the lifting guide rail 2 and the bending plate 13 are provided with clearance grooves, and the clearance grooves are rotatably connected with guide shafts that cooperate with the connecting belt 9, so as to guide the connecting belt 9.

[0028] See Figures 1-3 Preferably, the bending plate 13 is fixedly connected with a number of reinforcing fasteners 14 that cooperate with the lifting guide rail 2. The reinforcing fasteners 14 are all fixedly connected to the lifting guide rail 2, which can improve the connection stability of the lifting guide rail 2.

[0029] See Figures 1-3 Preferably, by adjusting the weight of the lifting seat 22, the lifting seat 22 does not move on its own when the driven seat 62 does not move, and the lifting seat 22 can move downward under the action of gravity when the driven seat 62 moves towards the lifting guide rail 2.

[0030] In the implementation of this utility model: When the vehicle body 1 is in normal use, the user holds the handle ring 16. At this time, there is a certain angle between the handle plate 15 and the vehicle body 1. The handle plate 15 does not contact the brake plate 3, and the first spring is in a natural state. After the user pushes the vehicle body 1 to a suitable position, he steps on the pedal 4. The pedal 4 rotates with its connection point with the vehicle body 1 as the center. Under the action of the drive linkage 41, the drive seat 5 moves downward. Under the action of the cooperating linkage 81, the driven seat 62 moves away from the lifting guide rail 2. In the initial stage of the movement of the driven seat 62, the guide post is located in the straight section. When the guide post moves to the spiral section, the rack 52 and the gear 61 disengage. The guide post moves in the spiral section, driving the drive shaft sleeve 7 to rotate forward. At this time, the ratchet 72 and the pawl 63 cooperate. The drive shaft sleeve 7 drives the driven shaft 6 to rotate, causing the driven seat 62 to move along the driven shaft 6, thereby adjusting the height of the lifting seat 22. When pedal 4 is released, the drive seat 5 returns to its original position under the action of the second spring. During this process, ratchet 72 does not engage with pawl 63, and driven shaft 6 does not rotate.

[0031] When the user releases the handle ring 16, the handle plate 15 rotates and presses down the brake plate 3 under the action of the torsion spring, thereby causing the brake block 33 to squeeze the wheel 11 and achieve braking of the vehicle body 1.

[0032] This utility model provides a small-scale on-site mobile device for machinery, which has the following advantages:

[0033] 1. By setting up structures such as the vehicle body, driven shaft, drive shaft sleeve and lifting seat, it can not only assist users in moving the machine and save manpower, but also freely adjust and lock the position of the buckle, which is suitable for the transfer of machines of different heights, thus expanding the adaptability of the device and meeting different usage needs.

[0034] 2. By setting up structures such as handle plates, brake plates, and brake blocks, the vehicle can automatically park when it is not in use. When the user releases the handle ring, the brake can be applied. The braking method is simple and quick, which improves the safety of the device.

[0035] In summary, the beneficial effects of this utility model are: it can assist users in transferring machinery, meet the needs of machinery transfer operations at different heights, expand the scope of application, and also realize automatic parking, ensuring good safety in use.

[0036] Of course, there may be many other embodiments of this utility model. Without departing from the spirit and essence of this utility model, those skilled in the art can make corresponding changes and modifications based on this utility model, but these corresponding changes and modifications should all fall within the protection scope of the appended claims of this utility model.
