Description

Technical Field

[0001] The utility model relates to the technical field of handling vehicles, in particular to a semi-electric pallet truck. Background Technique

[0002] The pallet truck is a logistics handling device, suitable for heavy-load and long-time cargo transfer working conditions, which can greatly improve the cargo handling efficiency and reduce the labor intensity. The connection between the top cover and the oil cylinder of the existing handling vehicle is realized by means of hinge or spherical positioning, etc. In actual work, the applicant found that when the oil cylinder is lifted and lowered, it does not maintain a vertical state, and there will be swing at the connection between the two. The non-vertical lifting of the oil cylinder of the handling vehicle increases the energy consumption and part wear, and makes the steering force heavier. There are many types of existing pallet trucks, for example:

[0003] Publication No. CN105217527A discloses a pallet truck, which uses a link mechanism in which the connection method between the top cover and the oil cylinder cooperates with the above connection method, so that when the oil cylinder jacks up the top cover or the oil cylinder descends, it remains in the direction perpendicular to the ground, improving the operation stability, reliability and energy utilization rate. However, there are still some deficiencies in the above device when in use. When handling an object, the oil rod is set to lift it, but after the object rises, the object is prone to shift due to gravity, which is likely to cause the object to tilt. And the above device lacks a mechanism for limiting the object.

[0004] Therefore, we proposed a semi-electric pallet truck that can well solve the above problems. Content of the Utility Model

[0029] Please refer to Figures 1 - 7 , the present invention provides the following technical solutions:

[0030] Embodiment 1: In order to solve the problem that when the handling vehicle on the current market handles objects, the oil bar is set for lifting, but after the object rises, the object is prone to shift due to gravity, which is likely to cause the object to tilt, and the above device lacks the problem of limiting the object. Reference can be made to the attached Figure 1 - attached Figure 4 , including a handling vehicle body 1, a group of handles 2 are installed at the left side position of the handling vehicle body 1, and a groove is penetrated and opened on the surface position of the handling vehicle body 1; further including: a group of connecting cross bars 3 are fitted and slid in the groove opened on the surface position of the handling vehicle body 1, a group of fixed rods 4 are fixed at the end positions of the connecting cross bars 3, a group of first elastic pins 5 are slidably arranged on one side position of the fixed rod 4, a group of first docking holes 6 are opened at one side position of the handling vehicle body 1 close to the groove opened on the surface position of the handling vehicle body 1, and a plurality of second docking ports 7 are equally spaced and opened at the lower position of the handling vehicle body 1 close to the groove opened by the handling vehicle body 1; the diameter of the first docking hole 6 is the same as the diameter of the second docking port 7, and the outer side of the first elastic pin 5 is composed of a spring and a pin, the head end of the spring is fixed on the outer side of the first elastic pin 5, and the tail end of the spring is fixed on the outer side position of the fixed rod 4. A group of threaded rods 401 are threadedly connected to the end of the fixed rod 4 away from the first elastic pin 5, and the first elastic pin 5 forms a clamping structure with the inside of the handling vehicle body 1 through the first docking hole 6.

[0031] First, when carrying the tray, one end of the carrier body 1 is inserted into the bottom position of the tray. Subsequently, by pulling the first elastic bolt 5, one end of the first elastic bolt 5 will slide inside the fixed rod 4, and one end of the first elastic bolt 5 will extend out of the outside of the first docking hole 6. Then, by rotating the connecting cross bar 3, both the connecting cross bar 3 and the fixed rod 4 will rotate. At this time, one end of the first elastic bolt 5 will be perpendicular, and one end of the fixed rod 4 is slid in the groove on the surface of the carrier body 1, so that the fixed rod 4 fits on one side of the tray. Additionally, according to actual needs, by rotating the threaded rod 401, the height of the outside of the threaded rod 401 is adjusted. At this time, the threaded rod 401 is in contact with the fixed rod 4.

[0032] Embodiment 2: In order to effectively unload the object and fully process the object, reference can be made to Appendix Figure 1 , Appendix Figure 2 and Appendix Figure 5 - Appendix Figure 7, a set of fixed motors 8 are fixed at one side position on the top of the carrier body 1. The output end of the fixed motor 8 is fixed at the top position of the vertical rod 9. The bottom position of the vertical rod 9 is connected to the outer side of the rod in the middle of the rotating block 11 through a bevel gear assembly 10. A set of connecting rods 12 are rotatably connected to the outer surface edge of the rotating block 11. The other end of the connecting rod 12 is rotatably connected to the left end of the push rod 13. The other end of the push rod 13 is slidably arranged inside the sliding sleeve 14. The other end of the sliding sleeve 14 is fixed to one side of the fitting plate 17. The bottom position of the fitting plate 17 is slidably arranged in a chute 18 opened at the top position of the carrier body 1. Embedding holes 16 are equidistantly opened on the surface of the push rod 13. A set of second elastic pins 15 are slidably arranged on the outer side of the sliding sleeve 14. One end of the second elastic pin 15 is snapped into a set of embedding holes 16 arranged inside the sliding sleeve 14. The middle part of the rotating block 11 is rotatably arranged on one side of the carrier body 1. The fitting plate 17 and the inside of the chute 18 form a sliding structure through the sliding sleeve 14. By starting the fixed motor 8 installed on the top of the carrier body 1, the vertical rod 9 fixed at the output end position of the fixed motor 8 rotates. At this time, the bottom position of the vertical rod 9 drives the rotating block 11 to rotate through the bevel gear assembly 10. At this time, the rotating block 11 will rotate at the outer side position of the carrier body 1. At this time, the rotating block 11 rotatably connected to the edge of the rotating block 11 moves, resulting in the rotating block 11 driving the connecting rod 12 to rotate. In addition, the connecting rod 12 will drive the fitting plate 17 to slide inside the chute 18 through the push rod 13. At this time, the fitting plate 17 moves stably, so that the fitting plate 17 can be limited to one side of the tray. Through the mutual fitting arrangement of the fixed rod 4 and the fitting plate 17, sufficient limiting treatment of the tray can be achieved. When it is convenient to unload the tray, by loosening the second elastic pin 15, one end of the second elastic pin 15 will be disengaged from the inside of the embedding hole 16. At this time, continue to rotate the rotating block 11. At this time, the push rod 13 will extend inside the sliding sleeve 14. Then, after adjusting to a suitable position, the rotation of the rotating block 11 will drive the push rod 13 to perform a pushing process. At this time, when the second elastic pin 15 is loosened, one end of the second elastic pin 15 will pass through the inside of the embedding hole 16. At this time, the moving range of the fitting plate 17 will change, so that the tray can be pushed down, thus facilitating the unloading process of the tray.
