[0024] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0025] Reference Figures 1-5 An industrial gantry crane that facilitates motor replacement is provided. This industrial gantry crane that facilitates motor replacement includes a drive motor 1, a gearbox 2, and a mounting plate 3. The top of the mounting plate 3 is symmetrically provided with a centering wedge cavity 302. A support frame is detachably installed in the centering wedge cavity 302 by means of an internal hexagonal bolt 5. The support frame is installed on the drive motor 1.

[0026] The support frame includes an inclined plate 401 mounted on the drive motor 1 and wedge blocks 403 corresponding to the centering wedge cavities 302. The inclined plate 401 is mounted on the wedge blocks 403, and the wedge blocks 403 have symmetrically provided second fixing holes 404. Hexagonal socket head cap screws 5 pass through the second fixing holes 404 and are threaded into threaded holes on the bottom of the centering wedge cavities 302. In application, the design of fixing the support frame (along with the drive motor 1) to the centering wedge cavities 302 using hexagonal socket head cap screws 5 achieves the detachable installation of the drive motor 1. Installation is simple; just loosening / tightening the bolts completes the disassembly and assembly of the drive motor 1, without the need for complicated tools or steps. At the same time, the wedge block 403 and the centering wedge cavity 302 cooperate. When the wedge block 403 is inserted into the centering wedge cavity 302 and the internal hexagonal bolt 5 is tightened, the inclined surface cooperation produces a self-centering effect. During the installation process, the drive motor 1 (through the support frame) will be automatically guided and accurately positioned to the correct centering position required by the gearbox 2, which greatly simplifies the most tedious and time-consuming centering adjustment process after replacing the drive motor 1.

[0027] Reference Figures 1-3 The bottom of the gearbox 2 is equipped with a limiting slide plate 201, and the top of the mounting plate 3 is provided with a limiting groove 301 corresponding to the limiting slide plate 201. The limiting groove 301 is adapted to the limiting slide plate 201 and is located between the centering wedge cavities 302. In application, the cooperation between the limiting slide plate 201 and the limiting groove 301 provides precise positioning and guidance for the installation of the gearbox 2 on the mounting plate 3, ensuring that the position of the gearbox 2 itself relative to the mounting plate 3 is fixed and accurate. At the same time, the limiting groove 301 is located between the two centering wedge cavities 302, further assisting the centering effect and restricting the movement of the gearbox 2, making its position stable, and providing a reliable reference for the drive motor 1 to achieve precise centering through the wedge structure.

[0028] Reference Figure 1 and Figure 2 The top edge of the mounting plate 3 is provided with a first fixing hole 303 for fixing. In application, the first fixing hole 303 provides a means to firmly fix the entire mounting plate 3 (together with the gearbox 2 and drive motor 1 on it) to the gantry frame or mounting base (such as a wall or steel structure), ensuring the stability of the entire drive unit during operation and preventing displacement or vibration.

[0029] Reference Figure 1 and Figure 2The bottom of the mounting plate 3 is equipped with a shock-absorbing pad 304. The shock-absorbing pad 304 is made of rubber and has a thickness of 3-5mm. In application, the rubber shock-absorbing pad 304 is installed at the bottom of the mounting plate 3, which can effectively absorb and isolate the vibration generated when the drive motor 1 and the gearbox 2 are running. At the same time, it reduces the noise and vibration transmitted to the mounting foundation, improves the stability of equipment operation, extends the service life of related components, and reduces the impact of vibration on the mounting foundation.

[0030] Reference Figure 4 and Figure 5 The inclined plate 401 is embedded with a honeycomb-shaped buffer cavity 402, which is filled with a high-damping silicone layer. In application, the honeycomb-shaped buffer cavity 402 embedded in the inclined plate 401 is filled with high-damping silicone, forming a high-efficiency buffer structure. The honeycomb structure provides good support and deformation space, and the high-damping silicone can effectively dissipate impact energy, thereby further enhancing the load-bearing frame (especially the inclined plate 401 part connected to the drive motor 1) to resist impact loads (such as start-stop impacts and accidental collisions), protecting the connection between the drive motor 1 and the gearbox 2, and reducing vibration transmission.

[0031] Reference Figure 4 and Figure 5 The inclined surface of the wedge block 403 and the contact surface of the centering wedge cavity 302 are plated with a hard chrome layer. In application, the hard chrome layer on the contact surface of the wedge block 403 and the centering wedge cavity 302 significantly improves the hardness, wear resistance and corrosion resistance of the contact surface, and ensures the durability of the wedge mating structure under repeated disassembly and assembly, load bearing and potential micro friction, prevents the centering accuracy from decreasing or jamming due to wear, and extends the service life of the key centering mechanism. At the same time, the surface of the hard chrome layer is smooth, which can reduce the frictional resistance during installation and disassembly to a certain extent, making the operation smoother.

[0032] The working principle of this utility model is as follows: When disassembling the old drive motor 1, the power is cut off to ensure that the equipment stops completely. Then, the internal hex bolt 5 is loosened, and the drive motor 1, together with the inclined plate 401 and the wedge block 403, is pulled out from the centering wedge cavity 302. Then, the power line and signal line of the drive motor 1 are disconnected, which makes it easy to disassemble the old drive motor 1 and the operation is simple and quick.

[0033] When installing a new drive motor 1, align the wedge block 403 on the new drive motor 1 with the centering wedge cavity 302 on the mounting plate 3, and then insert and pre-tighten the internal hexagon bolt 5. At this time, the inclined plane automatically guides the new drive motor 1 to be precisely aligned with the gearbox 2. Then, fully tighten the internal hexagon bolt 5, connect the wiring, and test the smoothness of operation by powering on to confirm that there is no abnormal vibration or noise. This facilitates the installation of the new drive motor 1 and is simple and quick to operate. This device not only facilitates the disassembly and assembly of the motor and is simple and quick to operate, but also solves the problem of the time-consuming and laborious manual centering adjustment required after replacing the motor in traditional gantry cranes. It can also greatly shorten the maintenance and replacement time and significantly improve the equipment maintenance efficiency and the operating efficiency of industrial gantry cranes.

[0034] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
