Description

Technical Field

[0001] The utility model belongs to the technical field of motor shell transportation, in particular to a pallet structure for stacking and transporting motor shells. Background Art

[0002] The motor is mainly composed of a stator, a rotor, a stator winding, a motor housing, an end cover, a bearing and other parts; the motor housing is a structure for installing the stator and other components inside it. The main function of the motor is to generate a driving torque as a power source for electrical appliances or various machines. Since the motor housing is an irregular shape similar to a hollow cylinder, it is not convenient for stacking and transportation; the existing transportation method is to pile the motor housings onto a transfer vehicle for transportation, which can easily cause collisions between them, easily causing damage to them and reducing product quality. If the motor housing is stacked and transported horizontally, rolling and shaking will occur along the axial direction, resulting in damage such as extrusion and bumping; if the motor housing is stacked vertically, it will jump or even fall over when bumped; both have the problem of unstable transportation and easy damage, which reduces product quality.

[0003] In view of the above-mentioned problems of instability and easy damage during stacking and transportation, the utility model designs a stacking and transportation pallet structure for motor casings. Utility Model Content

[0004] The purpose of the utility model is to provide a stacking and transporting pallet structure for motor shells, which, through the action of the pallet main body, the clamping assembly and the pressure plate assembly, can contact and resist the motor shells stacked on the pallet main body from the inner wall, so as to limit and stabilize them, and fix the stacked top in the vertical direction; ensure that they are not prone to shaking and jumping during the transport process, avoid tipping and damage to a great extent, and solve the above-mentioned problems of instability and easy damage during stacking and transport.

[0005] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0006] The utility model discloses a stacking and transfer pallet structure for motor shells, comprising a pallet body, a clamping assembly and a pressure plate assembly; a transfer groove for inserting and lifting a forklift is provided on the side of the pallet body; through holes are evenly provided on the pallet body, and a mounting tube is fixed on the inner wall of the through hole; a clamping assembly is assembled in the mounting tube; the clamping assembly comprises a mounting post and a clamping block, and the mounting post penetrates through and slidably cooperates with the clamping block; the outer side wall of the clamping block contacts and cooperates with the inner wall of the motor shell; a limited spacer is placed between each two adjacent layers of the motor shell, and the mounting post also penetrates through and slidably cooperates with the limited spacer; the pressure plate assembly comprises a circular pad, and an annular notch is provided at the bottom edge of the circular pad, and the mounting post also penetrates through and slidably cooperates with the circular pad, and the mounting post is threadedly connected with a nut at the circular pad.

[0007] Among them, when the motor shell is stacked on the pallet body, the bottom thread of the mounting column is installed in the mounting tube, and then the fixing block is inserted into the mounting column, so that the outer wall of the fixing block is just in contact with the inner wall of the motor shell and slides up and down; at least two through holes and mounting columns are placed inside the motor shell, and the two fixing blocks located at different positions and symmetrically distributed will limit the inner wall of the motor shell so that it cannot be horizontally offset; thereby ensuring that the multi-layer stacked motor shells are in a stable state, and at the same time, limiting pads are placed between each layer of motor shells to enhance the stability of the stacking.

[0008] As a preferred technical solution of the utility model, the through hole and the mounting tube are both circular structures; the inner wall of the mounting tube is provided with an internal thread, both ends of the mounting column are provided with external threads, and the bottom of the mounting column is threadedly matched with the internal thread of the mounting tube.

[0009] As a preferred technical solution of the utility model, the outer wall of the fixing block and the inner wall of the motor housing are both arc-shaped structures and fit each other, and the gap between them does not exceed 1mm-5mm, and the optimal gap range is no more than 1mm-3mm. The outer wall of the fixing block and the inner wall of the motor housing are slidably matched in the vertical direction.

[0010] As a preferred technical solution of the utility model, the fixing block, the limiting cushion block and the circular cushion seat are all provided with through holes, and the inner wall of the through hole is slidably matched with a mounting column.

[0011] As a preferred technical solution of the utility model, a clearance groove is also provided at the through hole on the circular cushion, and the nut is located in the clearance groove.

[0012] As a preferred technical solution of the utility model, the limiting pad includes a gasket, and fixing blocks are fixed on both sides of the gasket; the limiting pad enables the top and bottom of the motor housing to be effectively horizontally limited, thereby achieving the effect of improving stability.

[0013] As a preferred technical solution of the utility model, the through holes are located on both sides of the transfer trough.

[0014] As a preferred technical solution of the utility model, several groups of reinforced support cross plates are installed inside the pallet body, and the reinforced support cross plates are located between two adjacent through holes and above the transfer trough; since the motor housing is relatively heavy and the overall weight is large when stacked, when the structural strength of the pallet body is insufficient, it is necessary to strengthen the support cross plates to improve the support strength to ensure stability and safety during forklift transportation.

[0015] The utility model has the following beneficial effects:

[0016] 1. The utility model uses the functions of the pallet body, the clamping assembly and the pressure plate assembly to contact and hold the motor shells stacked on the pallet body from the inner wall, so as to limit and stabilize them, and fix the upper part of the stack in the vertical direction; ensure that it is not easy to shake and jump during the transportation process, and achieve the effect of limiting and fixing the motor shells stacked on the pallet body in the horizontal and vertical directions; it has the advantages of ensuring the stability of the stacking during the transportation process and avoiding tipping and damage.

[0017] 2. The utility model is designed with a through hole and a fixing component on the tray body, so that the position of the mounting column on the through hole can be adaptively selected according to the inner diameter of motor shells of various sizes and models, so as to achieve the effect of stacking and transporting motor shells of various sizes and models; it has the function of being applicable to various motor shells.
