Description
Technical Field
[0001] This utility model belongs to the field of maintenance equipment technology, specifically relating to a coal mine electromechanical maintenance support. Background Technology
[0002] Among the easily worn parts of coal mine electromechanical equipment, shafts are one of the components with the highest frequency of maintenance and replacement. In order to facilitate the maintenance and replacement of shafts, corresponding supports are often used for height lifting and support. However, the current general supports often only have a supporting function, and their adjustability and stability are poor. Moreover, in some environments with large height space restrictions, due to the large height of the equipment itself, the components are prone to contact with the outside, which is not conducive to the need for convenient maintenance. Utility Model Content
[0003] The purpose of this utility model is to provide a coal mine electromechanical maintenance support to solve the problems existing in the background art.
[0004] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows: A coal mine electromechanical maintenance support includes a base, with a braked moving wheel on the lower side of the base and a support mechanism on the upper end of the base; The support mechanism consists of a support cylinder, a U-shaped support frame, and a fixing component. The support cylinder is fixedly mounted on the upper side of the base. The U-shaped support frame is connected to the output shaft of the support cylinder and has its opening facing upwards and is matched with the shaft-shaped electromechanical component. The fixing component is located at the opening of the U-shaped support frame. The fixing assembly consists of a buckle plate, a lifter, and a pressure plate. The buckle plate is fastened to the U-shaped support frame to close the opening of the U-shaped support frame and is locked by bolts and nuts. The lifter is located on the upper side of the buckle plate, and the pressure plate is located on the lower side of the buckle plate, corresponding to the middle of the opening of the U-shaped support frame and is connected to the lifter in a transmission manner.
[0005] The lifting device consists of a motor, a screw, a slider, and a hinge rod. The screw is rotatably mounted on the upper side of the buckle plate via a connecting lug. The buckle plate has an opening in the middle of the screw. The screw is symmetrically provided with two bidirectional threaded rods in opposite directions. The slider and the hinge rod are a pair of rods, and there are two sets of rods. The two sets of rods are respectively connected to the threaded sections on both sides of the screw. The slider is threadedly connected to the screw. The hinge rod is hinged between the lower side of the corresponding slider and the upper side of the pressure plate.
[0006] The thickness of the hinge rod matches the width of the movable slot.
[0007] The U-shaped support frame has rollers symmetrically rotating inside the lower part of the opening.
[0008] This application has at least the following advantages compared to the prior art: This application, through the setting of a support mechanism, can more conveniently and stably support and fix the shafts of electromechanical equipment during maintenance and replacement, meeting the support needs of different types of shafts. At the same time, the lateral adjustment and longitudinal lifting mode of the lifting device can meet the maintenance needs of different narrow spaces and reduce the height of external components of the equipment.

[0013] The symbols for the main components are explained below: Base 1, support cylinder 11, U-shaped support frame 2, buckle plate 3, pressure plate 31, motor 32, screw 33, slider 34, hinge rod 35, movable groove 36, roller 4. Detailed Implementation
[0014] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.
[0015] like Figure 1-3 As shown, the present invention provides a coal mine electromechanical maintenance support, including a base 1, a moving wheel with brakes on the lower side of the base 1, and a support mechanism on the upper end of the base 1. The support mechanism consists of a support cylinder 11, a U-shaped support frame 2, and a fixing component. The support cylinder 11 is fixedly installed on the upper side of the base 1. The U-shaped support frame 2 is connected to the output shaft of the support cylinder 11 and its opening faces upward and matches the shaft-shaped electromechanical component. The fixing component is installed at the opening of the U-shaped support frame 2. The fixing assembly consists of a buckle plate 3, a lifter, and a pressure plate 31. The buckle plate 3 is fastened to the U-shaped support frame 2 to close the opening of the U-shaped support frame 2 and is locked by bolts and nuts. The lifter is located on the upper side of the buckle plate 3, and the pressure plate 31 is located on the lower side of the buckle plate 3 and corresponds to the middle of the opening of the U-shaped support frame 2 and is connected to the lifter in a transmission manner.
[0016] When performing maintenance support work, depending on the length of the shaft to be replaced, the shaft can be directly inserted between the U-shaped support frame 2 and the pressure plate 31, or the shaft can be inserted from the opening of the U-shaped support frame 2 after opening the buckle plate 3, so as to adapt to the replacement needs of shafts of different lengths. After the shaft is placed into the U-shaped support frame 2, the installation state of the shaft is adjusted to a suitable position and angle. Then, the shaft is fixed and clamped by the fixing component. The lifting device is used to adjust the height position of the pressure plate 31 in the U-shaped support frame 2, so as to achieve the effect of fixing and releasing the shaft by the pressure plate 31. This maintenance method is more convenient. The installation and fixing method can be flexibly adjusted according to the state of the shaft, and it can provide a stable fixing effect on the shaft, which is more conducive to maintenance needs.
[0017] The lifting device consists of a motor 32, a screw 33, a slider 34, and a hinge rod 35. The screw 33 is rotatably mounted on the upper side of the buckle plate 3 via a connecting lug. The buckle plate 3 has an opening 36 at the middle position of the screw 33. The screw 33 is symmetrically provided with two bidirectional threaded rods that are opposite to each other. The slider 34 and the hinge rod 35 are a pair of rods, and there are two sets of rods. The two sets of rods are respectively connected to the threaded sections on both sides of the screw 33. The slider 34 is threadedly connected to the screw 33. The hinge rod 35 is hinged between the lower side of the corresponding slider 34 and the upper side of the pressure plate 31.
[0018] When the motor 32 starts, it will drive the screw 33 to rotate. The screw 33 has two opposite threaded sections on both sides, which can make the sliders 34 and the hinge rod 35 on both sides move in opposite directions. That is, the pressure plate 31 is raised and lowered by the flipping action of the hinge rod 35. This method reduces the overall height of the fixed component and avoids inconvenience in operation in some narrow spaces or collision between the component and the external device.
[0019] The thickness of the hinge rod 35 matches the width of the movable slot 36.
[0020] This allows for the guidance and restriction of the movement of the pressure plate 31.
[0021] The lower side of the opening of the U-shaped support frame 2 is symmetrically equipped with rollers 4.
[0022] This makes it easier to fine-tune the installation status after the shaft is placed inside the U-shaped support frame 2.
[0023] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
