Description

Technical Field

[0001] The utility model relates to the technical field of air conditioners, and a power transmission device of an air handling unit: a fan motor assembly, mainly a multi-dimensional adjustable self-tightening motor slideway lifting device. Background Technique

[0002] As the most commonly used equipment in the air-conditioning industry, air handling units are widely used in industry and commerce. As an essential device inside the air handling unit, the fan motor assembly often encounters the problem of insufficient installation space. Usually, the fan motor assembly has a structure with the motor placed on the side or at the rear on the same horizontal base. The side-mounted motor assembly requires sufficient width space of the unit; while the rear-mounted motor assembly requires sufficient length space of the unit.

[0003] When there is not enough space in both the width and length directions to install the motor, a three-dimensional double-layer structure can be considered using the height space. When using the three-dimensional double-layer structure, a belt drive is used between the fan and the motor, and an appropriate tension needs to be applied between the belt and the pulley; the belt is prefabricated with a fixed size, and the distance between the two pulleys determines the size of the belt tension. How to adjust the center distance between the fan shaft and the motor shaft becomes the key to the belt drive; at the same time, since the distance between the upper fan shaft and the lower motor shaft is relatively large and the belt is long, the change in elongation during operation is relatively large, and the space requirement for motor adjustment is relatively large. How to effectively utilize the space for convenient and quick adjustment requires a flexible adjustment device. Adjusting the center distance in only one dimension cannot meet the needs of the entire operation cycle, and multi-dimensional adjustment becomes necessary. Summary of the Utility Model

[0004] The purpose of the utility model is to overcome the deficiencies existing in the prior art and provide a multi-dimensional adjustable self-tightening motor slideway lifting device.

[0005] The purpose of the utility model is achieved through the following technical solutions. A multi-dimensional adjustable self-tightening motor slideway lifting device includes an upper frame, a lower frame, a lifting frame, and a slideway. The upper frame is fixed above the lower frame and is used for installing a fan. The lifting frame is inclined and arranged on the lower frame, and the lifting frame can move up and down relative to the lower frame to form a multi-dimensional adjustable structure. A slideway is arranged on the inclined surface of the lifting frame, and the slideway is used for installing a motor. The fan shaft and the motor shaft are connected by a belt to form a transmission connection. The fan shaft and the motor shaft are parallel and spaced a certain distance in the vertical direction, so that the self-weight of the motor forms a gravity component parallel to the inclined surface of the lifting frame and downward.

[0006] Further, a plurality of connection holes are provided vertically on the columns of the lower frame, and the lifting frame is obliquely fixed on the lower frame through the connection holes and the positioning and locking device; the positioning and locking device includes a buckle and a fixing sleeve, wherein the buckle is used to cooperate with the card slot on the slideway and is connected to the motor through a fastener passing through the fixing sleeve.

[0007] Further, the lifting frame is assembled and welded by two rectangular tubes and two short rectangular tubes. U-shaped hole A is provided on the short rectangular tube for the installation and position adjustment of the slideway; U-shaped hole B is provided on the long rectangular tube for the position adjustment of the lifting frame.

[0008] Further, the lifting frame is installed through connection holes at different heights, so that the head and tail ends of the lifting frame are vertically lifted and lowered simultaneously, or one end of the lifting frame is fixed and the other end is adjusted in height to adjust the angle of the installation plane of the lifting frame, maintaining a reasonable slope for the self-weight sliding tension adjustment of the motor.

[0009] Further, after the motor is adjusted by self-weight sliding tension, a positioning and locking device is used to fix the lower part of the motor along the inclined plane to prevent the motor from sliding down.

[0010] Further, shock absorbers are provided at the bottom of the lower frame and are connected through shock absorber seats and square tube fixing frames.

[0011] The beneficial effects of the present utility model are as follows:

[0012] 1. The present utility model is a three-dimensional upper and lower layer combined positioning and adjustment device designed to reasonably utilize the empty height resources when the installation space of the fan motor group is limited. The fan is located in the upper layer and the motor is located in the lower layer. The lifting frame (motor support adjustment device) can be translated up and down, and the installation surface can be adjusted at multiple angles. The motor is installed on the inclined surface, increasing the flexibility and convenience of motor fine adjustment.

[0013] 2. Compared with the combination of side-mounted motors or rear-mounted motors on the traditional same horizontal base, the present utility model is multi-dimensionally adjustable. The lifting frame can be lifted and lowered vertically at both the head and tail ends for vertical long drop, generally for installation adjustment when the motor is in place; or one end of the lifting frame can be fixed and the other end can be adjusted in height to adjust the angle of the installation plane of the lifting frame, maintaining a reasonable slope which is beneficial to the self-weight sliding tension adjustment of the motor and increasing the adjustment space at the same time.

Detailed implementation manners

[0024] The following combines the accompanying drawings and specific implementation manners to further describe the present utility model. It should be noted that on the premise of no conflict, the following-described embodiments or technical features can be arbitrarily combined to form new embodiments.

[0025] The design purpose of the present utility model is to improve the utilization rate of the internal space of the air handling unit and solve the problem of insufficient internal space installation. By providing a multi-dimensional adjustable self-tightening motor slideway lifting device and optimizing the combination mode of the fan and the motor, the design purpose is achieved.

[0026] Such as Figure 1As shown in the figure, a multi-dimensional adjustable self-tightening motor slideway lifting device includes an upper frame 5, a lower frame 1, a lifting frame 2 and a slideway 3. The upper frame 5 is fixed above the lower frame 1 to form a three-dimensional double-layer integrated frame structure. The integrated frame is assembled and welded with square tubes that are light in weight, corrosion-resistant and firm, and its surface is galvanized. It can also be processed by painting (the paint color can be selected by oneself) or spraying and other processes to make the frame appearance more beautiful. A fan 6 is fixedly installed on the upper frame 5 (the upper part of the integrated frame). Since the fan impeller is a rotating component, the fan is fixedly installed on the upper frame to reduce vibration. The lifting frame 2 is inclined and arranged on the lower frame 1. The lifting frame 2 can move up and down relative to the lower frame 1 to form a multi-dimensional adjustable structure. A slideway 3 is arranged on the inclined surface of the lifting frame 2. The slideway 3 is used to install the motor 8, that is, the motor 8 is installed on the multi-dimensional adjustable lifting frame 2 below the fan 6 for motor installation and adjustment. The fan shaft and the motor shaft are connected by a belt 7. The fan shaft and the motor shaft are parallel and are spaced a certain distance in the vertical direction. The motor, as an adjustment component, can translate self-axially within a certain range. While keeping the motor shaft parallel to the fan shaft, its distance is adjusted so that the self-weight of the motor 8 forms a gravity component parallel to the inclined surface of the lifting frame 2 and downward.

[0027] As Figure 2 shown, a plurality of connection holes 1-2 are provided in the vertical direction on the columns 1-1 of the lower frame 1. The lifting frame 2 is inclined and fixed on the lower frame 1 through the connection holes 1-2 and the positioning and locking device 4. As Figure 4 shown, the positioning and locking device 4 includes a buckle 4-1 and a fixed sleeve 4-2. Among them, the buckle 4-1 is used to cooperate with a group of card slots 3-1 on the slideway 3, and is connected to the motor 8 through a fastener 12 (bolt and nut) passing through the fixed sleeve 4-2. The front end of the bolt abuts against the motor foot. The multi-dimensional adjustable lifting frame 2 changes the inclination angle of the inclined surface r, the vertical displacement in the height direction, the front-back sliding of the motor slideway and other multi-directional adjustments of the motor position by selecting different hole positions on the column 1-1 (square tube), and selects different pulleys, belts, etc. to adjust the fan speed. By changing the position of the fan-motor combination through this device, the purpose of saving space and realizing the design of the present utility model is achieved.

[0028] As Figure 3 shown, the lifting frame 2 is assembled and welded by two long square tubes 2-1 and two short square tubes 2-2. U-shaped holes A 2-3 are provided on the short square tubes 2-2 for the installation and position adjustment of the slideway 3; U-shaped holes B 2-4 are provided on the long square tubes 2-1 for the position adjustment of the lifting frame 2.

[0029] As Figure 5As shown, the lifting frame 2 is installed on the connection holes 1-2 at different heights, so that the front and rear ends of the lifting frame 2 can be lifted and lowered vertically at the same time, or the lifting frame 2 is fixed at one end, and the height of the other end is adjusted to adjust the angle of the lifting frame installation plane, maintaining a reasonable slope for the self-weight sliding tension adjustment of the motor 8. The motor is slidably installed on the multi-dimensionally adjustable lifting frame and fastened with bolts; the motor is installed and fixed on the motor slide. Due to the unique inclined slope design, the motor can be automatically tightened by its own gravity. There is no need to use motor tensioning assemblies to fix and tighten at both ends like the previous side motors or rear motors. It is only necessary to use the motor fixing block 15 to fix the motor under the inclined slope, and then use the front end of the bolt in the positioning locking device 4 to support the motor foot to prevent the motor from sliding down.

[0030] like Figures 6 - 8 As shown, there are four ways to adjust the motor position. Method 1: The motor adjusts the motor position by sliding forward and backward on the motor slide (such as Figure 6 Method 2: Adjust the motor position by adjusting the inclination angle of the multi-dimensional adjustable lifting frame slope (as shown in Figure 7 Method 3: Adjust the motor position by adjusting the up and down translation position of the multi-dimensional adjustable lifting frame (as shown in Figure 8 Method 4: Combine the first three methods to adjust the motor position. The multi-dimensional adjustment method of the motor allows for diversified selection of pulleys, belts, etc., which can better adjust the fan speed to suit different environments. The diversification of pulleys, belts, etc. is also conducive to adjusting the belt length, which can better reduce the belt vibration caused by excessive belt length, making the overall fan motor combination device run more stably and efficiently.

[0031] like Figure 9 As shown, the whole fan motor assembly equipment can reduce noise by setting a shock absorber 9 at the bottom of the lower frame 1, and connecting it with the square tube fixing frame 11 through the shock absorber seat 10. The shock absorber seat 10 is installed on the square tube fixing frame 11, and finally fixed on the box panel 14 of the air handling unit, and repaired and maintained through the inspection door 13. In addition, it can also be matched with functional sections such as mixing section, return air section, fresh air section, purification section, coil section, heating section, humidification section, and intermediate section. Different functional section combinations can achieve diversified air conditioning effects and meet the requirements of different environments.

[0032] It is understandable that, for those skilled in the art, any equivalent replacement or change to the technical solution and the concept of the utility model should fall within the protection scope of the claims attached to the utility model.
