[0002] A container handling hydraulic transport vehicle is a hydraulically driven vehicle specifically designed for loading, handling, and transporting containerized goods.

[0003] In the prior art, patent publication number CN221522035U discloses a hydraulic transport vehicle for loading and unloading boxes, including a forklift body, a cross slide bar, and a load-bearing plate. There are two cross slide bars, both of which are movably inserted into the forklift body along the width direction. The two cross slide bars are parallel to each other and move in opposite directions. A power component is installed in the forklift body to drive the cross slide bars to move. There are two load-bearing plates, which are respectively fixed to the ends of the two cross slide bars that are far apart from each other. The two load-bearing plates are arranged in parallel and are both arranged along the length direction of the forklift body.

[0004] This type of hydraulic transport vehicle for loading and unloading boxes has some problems. For example, the position of the transport frame body and the transport frame is fixed. While adjusting the spacing of the transport plates, the vertical height of the transport plates cannot be adjusted, which limits the convenience of transporting medical protective clothing boxes. At the same time, the spacing adjustment mechanism occupies a lot of space and has no protective mechanism, making it easy to be damaged during use. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the existing defects and provide a hydraulic transport vehicle for loading boxes, which can adjust the spacing between the transport plates without affecting the vertical position adjustment of the transport plates, while effectively saving working space and greatly improving the ease of use of the hydraulic transport vehicle for loading boxes, thus effectively solving the problems in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a hydraulic transport vehicle for handling loading boxes, including a transport frame, a lifting frame at the upper end of the transport frame, and a support mechanism;

[0007] Support mechanism: It includes a transport plate, a slide, a rack, a fixed shaft, and a driven gear. The slide is symmetrically arranged at the rear end of the lifting frame. The interior of the slide is slidably connected to the rear end of the vertically adjacent transport plate. The upper end of the rear surface of the left transport plate and the lower end of the rear surface of the right transport plate are fixedly connected to racks. The rear end of the lifting frame is provided with a drive compartment. The interior of the drive compartment is fixedly connected to a fixed shaft. The upper and lower ends of the fixed shaft are rotatably connected to driven gears. The driven gears are meshed with the vertically adjacent racks. This allows for adjustment of the transport plate spacing without affecting the vertical position adjustment of the transport plates. It also effectively saves working space and greatly improves the ease of use of the hydraulic transport vehicle for loading boxes.

[0008] Furthermore, the support mechanism also includes a rotating shaft, a worm gear, a transmission gear, and a worm. The rotating shaft is symmetrically rotatably connected to the inside of the drive chamber. A worm gear is fixedly connected to the upper end of each rotating shaft. A worm is rotatably connected to the rear end of the drive chamber. The threads at the left and right ends of the worm are in opposite directions. The worm gears are meshed with the corresponding ends of the worm. A transmission gear is fixedly connected to the lower end of the left rotating shaft and the middle part of the right rotating shaft. The transmission gears are meshed with the adjacent driven gear laterally. A drive button is fixedly connected to the left end of the worm to provide driving force for adjusting the spacing of the transport plates.

[0009] Furthermore, the rear end of the upper surface of the transport frame is provided with symmetrically distributed telescopic columns, the telescopic ends of which are fixedly connected to the rear end of the lifting frame, providing support, guidance and limiting function for the vertical movement of the lifting frame.

[0010] Furthermore, the lifting frame is provided with sliding cavity two at both ends, and the transport frame is provided with sliding cavity one at both ends. The rear ends of sliding cavity one and sliding cavity two are slidably connected with sliding seats. The front ends of the left and right sides of the lifting frame and the front ends of the left and right sides of the transport frame are fixedly connected with fixed columns. The sliding seats and the vertically diagonally adjacent fixed columns are rotatably connected with connecting rods. The two horizontally adjacent connecting rods are rotatably connected with connecting shafts to ensure the stability of the lifting frame.

[0011] Furthermore, a manual hydraulic cylinder is provided at the rear end of the upper surface of the transport frame. The upper end of the piston rod of the manual hydraulic cylinder is fixedly connected to the rear end of the lifting frame, and a drive rod is fixedly connected to the drive end of the manual hydraulic cylinder to provide driving force for the vertical movement of the lifting frame.

[0012] Furthermore, each of the transport plates has an arc-shaped surface at the end near the center of the lifting frame, and a baffle is fixedly connected to the upper surface of the transport plate away from the center of the lifting frame, which facilitates the medical protective clothing container to reach the upper part between the two transport plates, and at the same time provides side protection for the transport of the medical protective clothing container.

[0013] Furthermore, both ends of the transport frame are rotatably connected to movable wheels, and the rear end of the transport frame is fixedly connected to symmetrically distributed push rods, which facilitates the movement of the hydraulic transport vehicle used for loading and transporting the boxes.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This hydraulic transport vehicle for loading and unloading boxes has the following advantages:

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-3 This embodiment provides a technical solution: a hydraulic transport vehicle for loading and unloading boxes, including a transport frame 1, a lifting frame 2 at the upper end of the transport frame 1, and a support mechanism 3;

[0022] Support mechanism 3 includes a transport plate 31, a slide 32, a rack 33, a fixed shaft 34, and a driven gear 35. The slide 32 is symmetrically arranged at the rear end of the lifting frame 2. The interior of each slide 32 is slidably connected to the rear end of the vertically adjacent transport plate 31. The end of each transport plate 31 near the center of the lifting frame 2 is provided with an arc-shaped surface 13. The end of each transport plate 31 away from the center of the lifting frame 2 is fixedly connected with a baffle 14. The upper end of the rear surface of the left transport plate 31 and the lower end of the rear surface of the right transport plate 31 are both fixedly connected with racks 33 (two racks 33 are staggered). The rear end of the lifting frame 2 is provided with a drive gear 35. The drive chamber 4 has a fixed shaft 34 fixedly connected inside. Driven gears 35 are rotatably connected to both the upper and lower ends of the fixed shaft 34. Each driven gear 35 meshes with a longitudinally adjacent rack plate 33. The support mechanism 3 also includes a rotating shaft 36, a worm gear 37, a transmission gear 38, and a worm 39. The rotating shaft 36 is symmetrically rotatably connected inside the drive chamber 4. A worm gear 37 is fixedly connected to the upper end of the rotating shaft 36. A worm 39 is rotatably connected to the rear end of the drive chamber 4. The threads of the left and right ends of the worm 39 are in opposite directions. The worm gears 37 mesh with the corresponding ends of the worm 39. The lower end of the left rotating shaft 36 and the middle end of the right rotating shaft 36... Each component is fixedly connected to a transmission gear 38, which meshes with a laterally adjacent driven gear 35. A drive button is fixedly connected to the left end of the worm 39. Rotating the drive button rotates the worm 39, causing two worm wheels 37 to rotate in opposite directions. Each worm wheel 37 rotates, causing a vertically adjacent shaft 36 to rotate, which in turn rotates the transmission gear 38. Each transmission gear 38 rotates, causing a laterally adjacent driven gear 35 to rotate. Both driven gears 35 rotate around the central axis of the fixed shaft 34 in opposite directions, and each driven gear 35 acts on a longitudinally adjacent rack plate 33. This causes the left rack plate 33 to move to the right while the right rack plate 34 moves to the left. The movement of the rack plate 33 acts on the corresponding transport plate 31. Both transport plates 31 move towards the center of the lifting frame 2. At the same time, the rear ends of the transport plates 31 slide inside the corresponding slide groove 32, providing guidance and limiting for the overall movement of the transport plates 31. When the arc surface 13 of the two transport plates 31 contacts the medical protective clothing carrier, the medical protective clothing carrier is squeezed upward and then moves to the upper end between the two transport plates 31. When the baffle 14 contacts the side of the medical protective clothing carrier, the drive knob stops rotating.

[0023] The upper surface of the transport frame 1 has symmetrically distributed telescopic columns 7 at its rear end. The telescopic ends of the telescopic columns 7 are fixedly connected to the rear end of the lifting frame 2. The left and right ends of the lifting frame 2 are each provided with a second sliding cavity 9, and the left and right ends of the transport frame 1 are each provided with a first sliding cavity 8. The rear ends of both the first and second sliding cavities 8 and 9 are slidably connected to sliding seats 11. The front ends of the left and right sides of the lifting frame 2 and the front ends of the left and right sides of the inner walls of the transport frame 1 are fixedly connected to fixed columns. Connecting rods 10 are rotatably connected between the sliding seats 11 and vertically diagonally adjacent fixed columns. Connecting shafts 12 are rotatably connected between two horizontally adjacent connecting rods 10. The rear end of the upper surface of the transport frame 1 is provided with a manual hydraulic cylinder 5. The upper end of the piston rod of the manual hydraulic cylinder 5 is fixedly connected to the rear end of the lifting frame 2. A driving rod 6 is fixedly connected to the driving end of the manual hydraulic cylinder 5. The driving rod 6 reciprocates by pressing the driving end of the manual hydraulic cylinder 5, thus... Oil continuously enters the manual hydraulic cylinder 5, causing the piston rod of the manual hydraulic cylinder 5 to move upward, which in turn pushes the lifting frame 2 upward. At the same time, the telescopic ends of the two telescopic columns 7 extend along with the upward movement of the lifting frame 2, providing guidance and limiting for the vertical movement of the lifting frame 2. Simultaneously, the upward movement of the lifting frame 2 causes the two upper sliding seats 11 to slide forward inside the corresponding sliding cavity 9, causing the rear ends of the connecting rod 10 near the center of the lifting frame 2 to move forward. Under the action of the connecting shaft 12, the rear ends of the connecting rod 10 away from the center of the lifting frame 2 also move forward. At the same time, the lower sliding seats 11 slide forward inside the corresponding sliding cavity 8. The two horizontally adjacent connecting rods 10 form a scissor brace mechanism, providing stable support for the lifting frame 2. The upward movement of the lifting frame 2 causes the medical protective clothing carrier to move upward. When the medical protective clothing carrier reaches the required height, the pressing of the drive rod 6 is stopped.

[0024] The transport frame 1 has rotatably connected movable wheels 16 at both ends, and symmetrically distributed push rods 15 are fixedly connected to the rear end of the transport frame 1. The transport frame 1 is pushed by the push rods 15, and the movable wheels 16 rotate to realize the movement of the hydraulic transport vehicle.

[0025] The working principle of the hydraulic transport vehicle for handling loading boxes provided by this utility model is as follows: During operation, personnel push the transport frame 1 through the push rod 15, and the moving wheels 16 rotate to move the hydraulic transport vehicle. When the medical protective clothing box to be transported is located inside the transport frame 1, the personnel stop pushing the push rod 15 and rotate the worm gear 39 through the drive button. The rotation of the worm gear 39 drives the two worm wheels 37 to rotate. The two worm wheels 37 rotate in opposite directions. The rotation of the worm wheels 37 drives the vertically adjacent rotating shaft 36 to rotate, which in turn drives the transmission gear 38 to rotate. The rotation of the transmission gear 38 drives the horizontally adjacent driven gear 35 to rotate. Both driven gears 35 rotate around the central axis of the fixed shaft 34 in opposite directions. Each driven gear 35 acts on a longitudinally adjacent rack plate 33, causing the left rack plate 33 to move to the right while the right rack plate 34 moves to the left. The movement of the rack plates 33 acts on the corresponding transport plates 31, causing both transport plates 31 to move towards the center of the lifting frame 2. Simultaneously, the rear ends of the transport plates 31 slide within their corresponding grooves 32, providing guidance and limiting for the overall movement of the transport plates 31. When the arc-shaped surfaces 13 of the two transport plates 31 contact the medical protective clothing carrier, the medical protective clothing carrier is subjected to… The pressure is applied upwards, moving the device to the upper end between the two transport plates 31. When both baffles 14 are in contact with the sides of the medical protective clothing carrier, the operator stops turning the drive knob. Then, the operator repeatedly presses the drive end of the manual hydraulic cylinder 5 using the drive rod 6, causing oil to continuously enter the interior of the manual hydraulic cylinder 5. This causes the piston rod of the manual hydraulic cylinder 5 to move upwards, thus pushing the lifting frame 2 upwards. At the same time, the telescopic ends of the two telescopic columns 7 extend along with the upward movement of the lifting frame 2, providing guidance and limiting for the vertical movement of the lifting frame 2. Simultaneously, the upward movement of the lifting frame 2 drives the two upper sliding seats 11 to move in the corresponding sliding chambers 9. The forward sliding causes the rear ends of the connecting rods 10 near the center of the lifting frame 2 to move forward. Under the action of the connecting shaft 12, the rear ends of the connecting rods 10 away from the center of the lifting frame 2 also move forward. At the same time, the lower sliding seats 11 slide forward inside the corresponding sliding cavity 8. The two horizontally adjacent connecting rods 10 form a scissor brace mechanism, which provides stable support for the lifting frame 2. The lifting frame 2 moves upward, causing the medical protective clothing carrier to move upward. When the medical protective clothing carrier reaches the required height, the personnel stop pressing the drive rod 6, and then push the transport frame 1 through the push rod 15. The moving wheel 16 rotates to transport the medical protective clothing carrier.

Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
