[0030] A pipe lifting conveying device, which comprises a lifting mechanism 2, a tray 3, a guard plate 7 and a swing arm 6. The lifting mechanism 2 comprises a motor 21 and a vertically arranged screw rod 22. The motor 21 drives the screw rod 22 to rotate. The tray 3 is threadedly connected to the screw rod 22. The rotation of the screw rod 22 drives the tray 3 to lift. The screw rod 22 has a small transmission space and can realize large torque transmission. In a small space, high torque output can be realized to lift and transport pipes. The guard plate 7 is vertically arranged. The guard plate 7 contacts the tray 3 and limits the rotation of the tray 3. In the vertical direction, a limiting hole 711 is formed in the guard plate 7. The swing arm 6 is rotationally connected to the tray 3. The swing arm 6 rotates around the tray 3 and swings into or out of the limiting hole 711. The swing arm 6 has a swing dead angle. After the swing arm 6 swings into the limiting hole 711, the tray 3 moves downward and is limited by the swing dead angle of the swing arm 6. The swing arm 6 and the limiting hole 711 interfere with each other, limiting the downward movement of the tray 3. The swing arm 6 cooperates with the screw rod 22 to jointly bear the weight of the pipe and the tray 3. The swing arm 6 shares the stress received by the screw rod 22, avoiding the stress of the entire pipe and tray 3 being concentrated on the screw rod 22. This greatly improves the use environment of the screw rod 22 and prolongs the service life of the screw rod 22. Moreover, after the screw rod 22 fails, the tray 3 and the pipe will not fall. The swing arm 6 will support the tray 3 and the pipe, reducing the risk of the pipe and the tray 3 falling. The safety performance of the pipe lifting conveying device is improved.
[0031] In the embodiment, the lifting mechanism 2 can be a commercially available Lode SJA trapezoidal screw rod lifter.
[0032] A limiting protrusion 72 is arranged on the guard plate 7. The limiting protrusion 72 is vertically arranged. A limiting plate 4 is arranged on the tray 3. The first pulley 41 and the second pulley 42 are arranged on the limiting plate 4. The first pulley 41 and the second pulley 42 are arranged on opposite sides of the limiting plate 4. When the tray 3 is lifted in the vertical direction, the first pulley 41 and the second pulley 42 roll along the limiting protrusion 72. When the tray 3 moves up and down, the limiting protrusion 72 plays a guiding role. At this time, the first pulley 41 and the second pulley 42 slide along the limiting protrusion 72. This enables the tray 3 to move smoothly in the vertical direction, improving the stability and safety of the pipe lifting conveying device.
[0033] In the embodiment, the opposite sides of the tray 3 are respectively provided with the limiting plate 4 and the limiting protrusion 72. The stability of the tray 3 during lifting is further improved.
[0034] A connecting seat 5 is further arranged on the tray 3. The swing arm 6 is rotationally connected to the connecting seat 5. In the rotation direction of the swing arm 6, a strip-shaped hole 51 is formed in the connecting seat 5. A latch 61 is arranged on the swing arm 6. The latch 61 is arranged in the strip-shaped hole 51. The swing angle of the swing arm 6 is limited by the strip-shaped hole 51 to form a swing dead angle.
[0035] Preferably, the upper surface of the tray 3 extends to provide at least two partitions 31. Adjacent partitions 31 are arranged in parallel. The pipe fittings on the tray 3 are arranged between adjacent partitions 31, avoiding the pipe fittings on the tray 3 from rolling and falling, and improving the stability of the pipe lifting conveying device.
[0036] The limiting holes 711 are arranged in two rows. The swing arms 6 are also arranged in two rows. The number of swing arms 6 is increased to disperse the stress on a single swing arm 6, and improve the strength of the swing arm 6 and the limiting hole 711 structure.
[0037] Preferably, the guard plate 7 is provided with a clamping plate 71. The limiting hole 711 is arranged on the clamping plate 71. The clamping plate 71 is threadedly connected to the guard plate 7, so that the clamping plate 71 can be conveniently replaced when the limiting hole 711 is deformed, and the difficulty and cost of maintaining the limiting hole 711 are reduced.
[0038] The base 1 is also included, and the base 1 is arranged on the mounting plane. The base 1 horizontally extends to provide a force arm 11, and the lower surface of the force arm 11 contacts the mounting plane. The lifting mechanism 2 and the guard plate 7 are arranged on the base 1. The base 1 increases the contact area between the pipe lifting conveying device and the mounting plane, so as to improve the fixing stability of the pipe lifting conveying device.
[0039] The specific working process of the utility model is as follows:
[0040] Taking the height of lifting the pipe fittings as an example, first, the motor 21 drives the screw rod 22 to rotate, and the tray 3 is lowered to the feeding height. The pipe fittings are placed between the partitions 31, and then the motor 21 drives the screw rod 22 to rotate, and the tray 3 is lifted to the preset unloading height. During the lifting process, the first pulley 41 and the second pulley 42 slide along the limiting protrusions 72, respectively. After the tray 3 stops lifting, the operator actuates the swing arm 6 to make the swing arm 6 swing into the limiting hole 711. Then the unloading can be started, and the lifting of the pipe fittings is completed.
[0041] The technical features of the above-described embodiments can be combined arbitrarily. In order to make the description simple, all possible combinations of the technical features in the above-described embodiments are not described, but as long as the combinations of the technical features do not exist contradictory, they should be considered as the scope of the description.
[0042] The above-described embodiments only express several implementation manners of the utility model, and the description is relatively specific and detailed, but it should not be understood as a limitation on the scope of the utility model patent. It should be pointed out that for ordinary skilled persons in the art, without departing from the concept of the utility model, a number of modifications and improvements can be made, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent should be subject to the appended claims.
