Description

Technical Field

[0001] This utility model relates to air conditioning installation equipment, and in particular to a hoisting device for installing an outdoor air conditioning unit. Background Technology

[0002] During the installation of an air conditioner outdoor unit, the unit needs to be hoisted down from above and secured to an outdoor mounting frame. Current hoisting methods typically use a suspended basket. Workers and the outdoor unit are placed in the basket, and a lifting device lowers the basket to a suitable height before the workers remove the unit and secure it to the mounting frame. However, it's important to understand that the basket is suspended in the air with no points of leverage. When workers move the outdoor unit within the basket, the sudden shift in the center of gravity often causes the basket to sway violently. If workers are using their hands to lift the unit in this situation, it can easily lead to a safety accident.

[0003] Therefore, a hoisting device is designed to keep the suspended platform stable when moving the outdoor unit of the air conditioner out of the platform, so as to improve the safety of the outdoor unit installation. Utility Model Content

[0004] The purpose of this utility model is to provide a hoisting device for installing an air conditioner outdoor unit, so as to solve the problem that the hoisting basket is prone to violent shaking when the air conditioner outdoor unit is moved out of the basket.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A hoisting device for installing an air conditioner outdoor unit, comprising:

[0007] The basket has a discharge port on the side for removing the outdoor unit of the air conditioner, and two sliding grooves A on the bottom surface. The two sliding grooves A are arranged in parallel and one end extends to the side where the discharge port is located.

[0008] An extension mechanism is slidably disposed in slide groove A, and the outdoor unit of the air conditioner is mounted on the extension mechanism;

[0009] A push-pull mechanism is provided on the outside of the suspended basket and is drivenly connected to the extension mechanism to push the extension mechanism to slide along the slide rail A and move the air conditioner outdoor unit out of the suspended basket;

[0010] The counterweight mechanism is located at the bottom of the suspended platform and is connected to the push-pull mechanism so that it moves synchronously and in the opposite direction to the air conditioner outdoor unit when the push-pull mechanism pushes the extension mechanism out of the suspended platform.

[0011] Preferably, the basket is equipped with a safety door that covers the discharge port and can slide open to both sides when the air conditioner outdoor unit is installed.

[0012] Preferably, the extension mechanism includes a slide rail A slidably disposed in the slide groove A, the slide rail A being drivenly connected to the push-pull mechanism, and a clamping plate assembly being provided on the slide rail A. When the outdoor unit of the air conditioner is mounted on the slide rail A, the clamping plate assembly clamps the outdoor unit of the air conditioner with friction.

[0013] Preferably, the slide rail A has a slide groove B extending along its length. The clamping plate assembly includes a screw rod that can be rotatably disposed in the slide groove B. The screw rod has symmetrically arranged threads with opposite directions of rotation. A clamping plate is screwed to each end of the screw rod. The two clamping plates slide opposite each other in the slide groove B. A gear A is disposed on the end of the screw rod away from the discharge port. A motor is also disposed at the bottom of the basket. A gear B is coaxially disposed on the output shaft of the motor. A conveyor belt is wound around the gear A and the gear B.

[0014] Preferably, the push-pull mechanism includes a connecting plate connected to two slide rails A and a telescopic cylinder installed on the side of the basket facing away from the discharge port, wherein the telescopic cylinder is drivenly connected to the connecting plate.

[0015] Preferably, the counterweight mechanism includes two slide rails B disposed at the bottom of the basket, the slide rails B being parallel to the slide rail A, and a support plate slidably mounted between the two slide rails B. A counterweight is connected to the end of the support plate away from the discharge port. At least one return spring is disposed between the support plate and the basket, one end of the return spring being connected to the side of the support plate away from the discharge port, and the other end being connected to the side of the bottom of the basket near the discharge port. A traction rope is also connected to the side of the support plate near the discharge port, and the traction rope passes through the side of the basket facing away from the discharge port and is connected to the push-pull mechanism.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] Through the aforementioned structure, this solution enables the counterweight mechanism to maintain the basic stability of the basket's center of gravity by driving the counterweight blocks to move in the opposite direction during the removal of the outdoor unit from the basket. This reduces the severe shaking of the basket during the removal of the outdoor unit, thereby improving the safety of the outdoor unit installation process. Attached Figure Description

[0023] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0024] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0025] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0026] like Figures 1-4The diagram shows a hoisting device for installing an air conditioner outdoor unit, including a suspended platform 1. The platform is connected to a lifting mechanism installed on the roof using slings. A discharge port 11 is provided on the side of the platform facing the wall, allowing workers to easily remove the outdoor unit from the platform during installation. Simultaneously, two parallel extending grooves A12 are provided on the ground of the platform 1, one end of which extends to the side of the platform 1 where the discharge port 11 is located, to ensure... Figure 3 The extension mechanism 2, which is installed in the slide groove A12, can slide along the extension direction of the slide groove A12 to the outside of the basket 1.

[0027] Specifically, Figure 2 As shown, when the outdoor unit of the air conditioner is in the ready state, its entirety is in the basket and simultaneously mounted on the extension mechanism 2, so that when part of the extension mechanism slides out of the basket, it can move the outdoor unit of the air conditioner mounted above out synchronously.

[0028] In addition, a push-pull mechanism 3 is installed on the outer side of the basket 1 facing away from the discharge port 11. This push-pull mechanism is driven to the extension mechanism 2. When the air conditioner is removed, the push-pull mechanism can push the extension mechanism outward from the basket 1.

[0029] Finally, in order to ensure that the overall center of gravity of this structure remains stable when the outdoor unit of the air conditioner is moved out of the basket, a set of counterweight rod mechanism 4 is also provided at the bottom of the basket 1. The counterweight mechanism is connected to the push-pull mechanism 3, and when the push-pull mechanism 3 pushes the extension mechanism 3 outward, it can synchronously pull the counterweight mechanism 4 to move in the opposite direction to the extension direction of the extension mechanism 2, so as to achieve the balance of both sides of the basket.

[0030] In addition, to enhance safety, a safety door 13 is provided at the discharge port 11 of this solution. This safety door is a sliding door, which can close and lock the discharge port 11 when the air conditioner outdoor unit is being lifted, and can be moved and opened when the air conditioner outdoor unit needs to be moved out of the basket 1.

[0031] It is important to know that, such as Figure 3 , Figure 4 As shown, the extension mechanism 2 in this solution includes a slide rail A21 that is slidably fitted in the slide groove A12. The slide rail A21 is driven to the push-pull mechanism 3. The push-pull mechanism 2 can extend the slide rail A along the slide groove A to the outside of the basket or retract it into the basket by telescoping. At the same time, a clamping plate assembly 22 is also provided on the slide rail A. This clamping plate assembly can clamp the air conditioner outdoor unit after it is placed on the slide rail A to prevent the air conditioner outdoor unit from slipping off the slide rail A when the slide rail A moves the air conditioner outdoor unit out of the basket.

[0032] Furthermore, it should be noted that in the above solution, the clamping plate assembly 22 preferably has automatic clamping and automatic release functions after the air conditioner outdoor unit is moved onto the external mounting bracket. To this end, the slide rail 21 in this solution has a groove B211 extending along the length of the slide rail A. The clamping plate assembly 22 includes a screw 221, which is rotatably mounted in the groove B. A clamping plate 222 is screwed to each end of the screw B. Simultaneously, a gear A223 is installed on the inner end of the screw away from the discharge port. For example... Figure 3 , Figure 4 As shown, a motor 225 is fixedly installed on the ground of the suspended platform. A gear B224 is coaxially connected to the output shaft of the motor. A transmission belt 226 is wound around gears A and B. Driving the motor alone can rotate the screw, thereby moving the clamping plates on the screw. It should be noted that to ensure the stability of the clamping plate movement, the clamping plates 222 are slidably positioned in the sliding groove B. Furthermore, to ensure that the two clamping plates move towards each other when the screw rotates, the threads on the screw are symmetrically arranged and reversed, with the middle as the boundary.

[0033] like Figure 4 As shown, the push-pull mechanism 3 in this scheme specifically includes a connecting plate 31 that is simultaneously connected to two slide rails A21, and a telescopic cylinder 32 installed on the outer side of the side wall of the basket 1 facing away from the discharge port 11. It should be noted that the telescopic rod of the telescopic cylinder passes through the basket and is driven to connect with the connecting plate, so that the slide rail A21 can slide in the slide groove A under the action of the telescopic cylinder.

[0034] Furthermore, it should be noted that the counterweight mechanism 4 in this solution includes two slide rails B41 located at the bottom of the suspended platform, which are parallel to slide rail A. A support plate 42 is also provided between the two slide rails B41, and this support plate can slide along the extension direction of the slide rails. Figure 3 As shown, a counterweight 43 is connected to the side of the support plate away from the discharge port 11. The weight of this counterweight is close to that of the outdoor unit of the air conditioner. At the same time, at least one return spring 44 is also provided between the support plate and the suspended basket. One end of the return spring is connected to the side of the support plate 42 away from the discharge port 11, and the other end is connected to the bottom of the suspended basket 1 near the discharge port 11. Figure 2 , Figure 4 As shown, a traction rope 45 is connected to the side of the support plate near the discharge port. This traction rope passes through the bottom of the basket to the side of the basket away from the discharge port, then passes through the side wall of the basket and connects to the connecting plate in the push-pull mechanism. When the push-pull mechanism pushes the slide rail A outward, the traction rope pulls the counterweight on the support plate to move in the opposite direction to the movement of the outdoor air conditioner unit. This ensures that the center of gravity does not change drastically.

[0035] Working Principle: When installing an air conditioner outdoor unit, the worker first places the unit in the suspended basket and mounts it on slide rail A, where it is held by the clamping plate assembly. Then, the basket is lowered to the same height as or slightly higher than the support surface of the mounting frame (approximately 5cm). Next, the worker opens the safety door and extends the telescopic cylinder in the push-pull mechanism, pushing slide rail A out of the basket. During this process, the outdoor unit moves out of the basket simultaneously, while the counterweight moves in the opposite direction of the outdoor unit's movement under the pull rope, ensuring the stability of the basket's overall center of gravity. Once the outdoor unit is above the mounting frame, the worker lowers the basket again to place the unit on the frame, where it can then be secured with bolts. After the outdoor unit is installed and secured, the worker controls the motor to release the clamping plate assembly. Finally, the basket is lowered again to completely disengage the clamping plate assembly from the outdoor unit. After the above steps are completed, the telescopic cylinder in the push-pull mechanism retracts, and the support plate returns to its initial position under the action of the return spring. At this point, the next air conditioner outdoor unit can be hoisted. This solution prevents the basket from swaying violently due to rapid changes in the center of gravity when workers move the air conditioner outdoor unit out of the basket, effectively ensuring the safety of the air conditioner outdoor unit installation.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
