DETAILED DESCRIPTION

[0018] In order to clearly illustrate the technical features of the present invention, the present invention is described in detail below through specific implementation methods and in conjunction with the accompanying drawings.

[0019] In addition, in the description of the present invention, it should be understood that the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0020] like Figure 1-2 As shown, a pump station gate slot grille lifting and handling device includes a frame 1, four worm gear assemblies 6, four hooks 4 and a driving device.

[0021] The frame 1 has four legs 103 , and running wheels 2 are provided below the four legs 103 . The running wheels 2 enable the frame 1 to form a transport trolley, which can not only lift the grille but also transport it.

[0022] The above four worm gear assemblies 6 are arranged in a square shape. The worm wheel 601 in each worm gear assembly 6 is rotatably set on the frame 1. Specifically, the rotating shaft of the worm wheel 601 is perpendicular to the rotating shaft of the worm 602. The worm 602 is vertically threaded in the threaded hole 15 of the frame 1. The square arrangement ensures that the hook 4 below can be hung at four positions of the grille, which is more stable. At the same time, the reason for adopting the worm gear structure is that the worm 602 can be raised and lowered while rotating. Before the hook 4 below contacts the grille, the hook 4 rotates with the rotation of the worm 602. When the worm 602 descends, the worm 602 drives the hook 4 to descend, and the hook 4 enters the bottom of the grille from the gap of the grille.

[0023] The above four hooks 4 are movably arranged at the bottom end of the worm 602 in the four worm gear assemblies 6. The activity here refers to a rotational connection, such as a hinge or a universal connection. The hook 4 is arranged at the bottom end of the worm 602 and can rotate and rise and fall with the worm 602. The worm 602 descends, the worm 602 drives the hook 4 to rotate and descend, and the hook 4 enters the bottom of the grille from the gap of the grille, and then the worm 602 rises, the worm 602 drives the hook 4 to rotate and rise. When the hook 4 rises to contact the grille, the hook 4 begins to bear the weight. The hook 4 hooks the grille and the load is enough to make the hook 4 not rotate with the worm 602. Therefore, the hook 4 has a relative rotation relative to the worm 602, and the worm 602 rotates and rises alone in the threaded hole 15 until the grille is lifted. Then the grille can be moved to other positions by pulling the frame 1 by an external machine or manually.

[0024] The above-mentioned driving device is simultaneously connected to the four worm gear assemblies 6 to provide power for the rotation of the worm 602. Since the grille is roughly between 200-300 kilograms, it is more laborious to manually rotate the worm 602, and four people are required to rotate the worm 602 at the same time, which requires more manpower. Driving the four worm gear assemblies 6 together through the driving device can not only save a lot of manpower, but also this method of rotating the worm 602 is easier and faster, which will make it faster to lift and move the gate slot grille.

[0025] Furthermore, the structure of the above-mentioned driving device specifically includes a motor 12, which is movably connected to the frame 1 through a support rod 13, and the output shaft of the motor 12 is vertically arranged, and a first sprocket 10 is connected to the output shaft, and the worm wheel 601 in each worm gear assembly 6 is connected to the second sprocket 7 through a bevel gear 9, and the first sprocket 10 is respectively connected to the four second sprockets 7 through chains 5. The output shaft of the motor 12 rotates to drive the first sprocket 10 to rotate, and the rotation of the first sprocket 10 is transmitted through the chain 5, and the worm wheel 601 in the four worm gear assemblies 6 rotates to drive the worm 602 to rotate and rise and fall in the threaded hole 15.

[0026] Furthermore, in order to avoid power supply by wires which would hinder the movement of the frame 1 , the driving device further includes a battery pack 11 , which is disposed on the support rod 13 , and is connected to the motor 12 to supply power to the motor 12 .

[0027] Furthermore, in order to increase the scope of application of the lifting and handling device of the present application, that is, to be able to lift and carry grilles of different sizes, two front and rear cross beams 102 and two left and right cross beams 101 are connected in the middle of the above-mentioned four legs 103, and the two front and rear cross beams 102 and the two left and right cross beams 101 are all arranged horizontally, and each front and rear cross beam 102 is provided with a guide groove 3, and the guide grooves 3 on the two front and rear cross beams 102 are arranged opposite to each other, and the two left and right cross beams 101 are arranged in parallel and sliding in the guide groove 3. When the width of the grille is small and the hook 4 cannot extend into the gap of the grille, the distance between the two left and right cross beams 101 can be adjusted to make the hook 4 adapt to the width of the grille.

[0028] Correspondingly, because the support rod 13 is connected to the two left and right cross beams 101 of the frame 1, it is necessary to ensure that the support rod 13 can slide relative to the left and right cross beams 101. In order to meet this requirement, a guide rail 14 is provided on the lower surface of the support rod 13, and the two left and right cross beams 101 are slidably set in the guide rail 14 through the slider 8 connected thereto. When the two left and right cross beams 101 need to adjust their distance, the two left and right cross beams 101 slide in the guide grooves 3 of the two front and rear cross beams 102. At the same time, the two left and right cross beams 101 slide relative to the support rod 13, which can ensure that the position of the motor 12 on the support rod 13 remains basically unchanged.

[0029] Furthermore, among the above-mentioned four running wheels 2, two running wheels 2 are fixed wheels, and the other two running wheels 2 are universal wheels. The universal wheels can play a role in steering and direction fine-tuning, and the two fixed wheels play a role in fixing the working surface, so that the device can move back and forth in a straight line parallel to the gate slot, preventing the running wheels 2 from slipping into the gate slot.

[0030] Furthermore, in this embodiment, the hook 4 is universally connected to the bottom end of the worm 602 via a universal connector, so that the hook 4 can enter the gap of the grille and enter below it, and can also ensure the rotation of the worm 602 after the grille is hooked up.

[0031] The above-mentioned specific implementation manner cannot be used as a limitation on the protection scope of the present utility model. For those skilled in the art, any replacement, improvement or change made to the implementation manner of the present utility model falls within the protection scope of the present utility model.

[0032] The matters not described in detail in the present invention are all known technologies to those skilled in the art.
