Description

Technical Field

[0001] The utility model belongs to the technical field of plate chain bucket elevators, and in particular relates to a motor mounting base for a plate chain bucket elevator. Background Art

[0002] During the installation of large motors, such as mining motors or hoist motors, the motors are often hoisted to the mounting base due to their large size and weight, and then fixed by bolts. Since the hoisting method cannot accurately control the landing point of the motor, when fixing the bolts, the workers often need to use cylinders, crowbars or hammers to fine-tune the position of the motor in order to align the motor mounting holes with the base mounting holes. In addition, the fine-tuning distance and position are not controllable, so the fine-tuning process of the motor is very time-consuming and labor-intensive, and the operation is extremely inconvenient.

[0003] The Chinese patent document with the announcement number CN202696350U discloses a large-scale mining motor installation position adjustment device, which relates to an adjustment device for mining motors. It solves the problems of high cost of existing oil cylinder adjustment; poor adjustment accuracy and high destructiveness of crowbars and hammers. Steel plates with threaded holes are arranged around the mounting surface of the motor base, and bolts with nuts are threadedly connected to the steel plates. Threaded holes are processed below the mounting surface of the motor base and perpendicular to the mounting surface. Screws are installed in the threaded holes, and an adjustment plate can be placed between the mounting surface and the mining motor.

[0004] In the above patent solution, the radial position adjustment of the motor requires the rotation of at least four screws, which is less harmful to the motor, but inconvenient to operate. In addition, when the motor is lifted to install the adjustment plate or gasket, the screws used for lifting are located under the base, and large and heavy motors are often installed on the ground, and there is no space reserved at the bottom, so the screws used for lifting at the bottom are not easy to rotate and adjust. Utility Model Content

[0005] In order to overcome the technical problem in the prior art that large motors need to be fine-tuned and gaskets placed after hoisting, while the commonly used arrangement of adjusting screws is not convenient for manual operation; one purpose of the utility model is to provide a plate chain bucket elevator motor mounting base, which connects two L-shaped plates by rotating on the mounting plate. When the motor is hoisted, the L-shaped plate is tilted to provide a guide for the motor, and can be rotated to a vertical position under the gravity of the motor to limit the motor. At the same time, the L-shaped plate can also lift the motor when rotated by manual operation, so as to facilitate the placement of gaskets under the motor.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solutions: a plate chain bucket elevator motor mounting base, comprising a mounting plate and two positioning parts symmetrically arranged on the mounting plate; the positioning part comprises an L-shaped plate, the L-shaped plate is rotatably connected to the upper end of the mounting plate; a lifting screw, the lifting screw is rotatably connected to the mounting plate for driving the L-shaped plate to rotate; a fixing screw, the fixing screw is rotatably connected to the mounting plate for limiting the rotation of the L-shaped plate; the L-shaped plate comprises a main board and a support plate perpendicular to each other; wherein the rotation axes of the support plate and the L-shaped plate are respectively located on both sides of the main board; the support plate is located on the side facing the motor; the lifting screw is against the side of the main board away from the motor.

[0007] When hoisting the motor, there is an angle between the L-shaped plate and the horizontal plane of the mounting plate; when the motor is lowered, the motor is pressed on the support plate to rotate the main board toward the motor, automatically aligning the position of the motor in the center; after the motor is lowered, the main board is vertical and abuts against both sides of the motor seat, and under the locking of the fixing screws, the horizontal movement of the motor is limited, thereby eliminating the need to fine-tune the horizontal position of the motor.

[0008] In addition, by rotating the lifting screw so that the lifting screw drives the L-shaped plate to rotate, one side of the motor can be lifted, making it easier to insert an adjustment plate or gasket underneath. At this time, on the other side of the motor, the other L-shaped plate rotates, making it easier to flip and lift the motor while preventing the motor from sliding sideways and shifting, thereby facilitating adjustment and improving the safety of operation.

[0009] Specifically, a rotating shaft is arranged on the side of the L-shaped plate away from the motor; the rotating shaft is rotatably connected to the mounting plate; a notch is arranged at the lower end of the outer wall of the rotating shaft; and the fixing screw can selectively abut against the notch or the outer wall of the rotating shaft.

[0010] When the fixing screw abuts against the outer wall of the rotating shaft, the rotation of the L-shaped plate is hindered, so that the L-shaped plate and the mounting plate have an angle, and can abut against the support plate when the motor is hoisted; when the fixing screw abuts against the notch, the rotation of the L-shaped plate is restricted. At this time, the main board is in a vertical state and abuts against the side wall of the motor, thereby limiting the horizontal movement of the motor.

[0011] Preferably, an extension plate is provided at the lower end of the L-shaped plate; and the lifting screw can selectively abut against the extension plate.

[0012] The support plate is located above the extension plate, and the L-shaped plate forms a lever, so the process of lifting the screw to lift the motor is more labor-saving.

[0013] Preferably, a groove is provided at the connection between the main board and the support board.

[0014] After the motor is installed, the main board abuts against the installation surface of the motor. When the motor is lifted up and turned over, the groove avoids friction and extrusion between the motor and the main board, reduces stress concentration, and makes the operation more labor-saving.

[0015] Furthermore, the upper end of the mounting plate is provided with four reinforcing plates respectively close to the four corners; the upper end of the mounting plate is provided with two vertical plates respectively rotatably connected to the corresponding L-shaped plates; the vertical plate is located between two adjacent reinforcing plates.

[0016] Preferably, an accommodation area is provided between the vertical plate and the outer edge of the mounting plate; the fixing screw and the lifting screw are respectively located in the accommodation area.

[0017] The fixing screw and the lifting screw do not protrude outward, and the appearance is neat, thereby avoiding scratches caused by accidental touch.

[0018] Preferably, a rectangular steel beam is provided at the lower end of the mounting plate; the motor and the reduction box are simultaneously mounted on the rectangular steel beam; and reinforcing ribs are respectively provided on both sides of the accommodating area between the rectangular steel beam and the mounting plate.

[0019] The existing base design uses H-shaped steel as the main material, but there are problems such as insufficient rigidity and large vibration during driving operation. Replacing the H-shaped steel with rectangular steel can improve and enhance the rigidity without increasing the cost. The setting of the reinforcing ribs further ensures the stability of the motor installation.

[0020] Specifically, a rotation hole rotatably connected to the L-shaped plate is provided on the upper end of the vertical plate; a first threaded hole communicating with the lower part of the rotation hole is provided on the side of the vertical plate; and the fixing screw is rotatably connected in the first threaded hole.

[0021] Specifically, two lower through slots are provided through the upper end of the mounting plate; and the extension plate can be selectively located in the lower through slots.

[0022] Preferably, two ends of the vertical plate are respectively against the reinforcing plate.

[0023] Compared with the prior art, the utility model has the following beneficial effects: when the L-shaped plate is tilted, it can provide guidance for the motor hoisting, and rotate to vertical under the action of the motor's gravity, thereby providing a limit for the horizontal movement of the motor, without the need to fine-tune the motor, and at the same time improve the stability of the motor installation, simplifying the motor installation process. The L-shaped plate can also lift one side of the motor under the action of the lifting screw, which is convenient for placing gaskets or adjustment plates, while the L-shaped plate on the other side supports the motor to rotate, which is convenient for the motor to flip and can prevent the motor from sliding sideways, thereby improving safety.
