Technical Field
[0001] This utility model relates to the field of lifting structure technology, specifically a lifting structure for installing a central integrated air conditioner. Background Technology
[0002] Central air conditioning is a type of air conditioning system. A central air conditioning system consists of one or more cold and heat source systems and multiple air conditioning systems. It uses the principle of liquid vaporization refrigeration to provide the required cooling capacity to offset the cooling load of the indoor environment. The heating system provides the required heat to offset the heat load of the indoor environment. Central air conditioning systems are mostly installed on the roof, and a lifting platform is generally required when installing the air conditioner.
[0003] When workers assemble central air conditioning units, the stability of the work platform is required. In the existing technology, brake wheels are installed at the bottom of the platform to facilitate its movement. However, when the platform is fixed by the braking ability of the brake wheels alone, the platform's stability is not high and its reliability is low. At the same time, it lacks convenience for the work platform. Utility Model Content
[0004] The purpose of this utility model is to provide a lifting structure for the installation of a central integrated air conditioner. By using this device, the problem of low stability and reliability of the platform when brake wheels are added to the bottom of the platform for easy movement is solved. At the same time, the platform lacks convenience.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a lifting structure for installing a central integrated air conditioner, comprising a mobile platform, a fixed platform mounted on the upper end of the mobile platform, and a lifting platform mounted on the upper end of the mobile platform. The mobile platform includes a mobile plate, and a roller assembly is installed through the upper end of the mobile plate. A square hole is formed at the upper end of the mobile plate, and a square hole is formed on one side of the square hole. The roller assembly includes a connecting rod, and a fixed rod is rotatably mounted at the lower end of the connecting rod. A rotating column is installed through the upper end of the fixed rod, and the rotating column is rotatably connected to the fixed rod. The upper end of the rotating column is fixedly connected to the connecting rod. A clip and rod are fixedly mounted on the outer side of the lower end of the rotating column, and the clip and rod match the square hole. The fixed rod matches the square hole. A rotating shaft is installed through the lower end of the fixed rod, and the upper end of the rotating shaft is rotatably connected to the mobile plate. A U-shaped connecting plate is fixedly mounted on the lower end of the rotating shaft, and the U-shaped connecting plate is fixedly connected to the rotating shaft. Next, rollers are rotatably installed on the inner side of the U-shaped connecting plate. Multiple square grooves are opened at the upper end of the rollers. The square grooves match the fixed rods. The fixed rods slide through the U-shaped connecting plate and are slidably connected to it. In the initial state, the clip and rod are located at the upper end of the moving plate and are at a 90-degree right angle to the square hole. The fixed rod is away from the square groove. The upper half of the fixed rod is located at the upper end of the moving plate, and the lower half of the fixed rod is located inside the square hole. It does not pass through the rotating shaft. The rollers can rotate in multiple directions to adjust the direction and position of the moving plate. When we need to fix the moving platform, we rotate the connecting rod to drive the clip and rod to rotate synchronously. When the clip and rod rotate to the matching position with the square hole, the fixed rod falls into the square groove through the rotating shaft and the U-shaped connecting plate. The clip and rod fall into the square hole for fixation. The fixed rod fixes the rotating shaft, the U-shaped connecting plate and the rollers, thereby fixing the moving platform.
[0006] Preferably, the upper end of the movable plate is provided with a square groove II, which matches the lifting platform. A push rod is fixedly installed on the upper end of the movable plate near the fixed platform. When we need to move the movable platform, we can change the direction and position of the movable platform by pushing the push rod. When not in use, the lifting platform is fixed by the square groove II provided on the upper end of the movable plate.
[0007] Preferably, the fixed platform includes a second fixed rod. An electric hoist is fixedly installed at the upper end of the second fixed rod. Both ends of the electric hoist are connected to connecting ropes. A support plate is fixedly installed at the lower end of the second fixed rod. The lower end of the support plate is fixedly connected to a movable plate. Two sets of T-slots are provided on the side of the support plate near the lifting platform. A limit plate is fixedly installed at the upper end of the T-slots. The T-slots match the lifting platform. Two sets of connecting rods are fixedly installed at the lower end of the second fixed rod. Connecting ropes pass through the connecting rods and are fixedly connected to the lifting platform. When the lifting platform needs to be moved, the connecting ropes are retracted by activating the electric hoist, thus moving the lifting platform connected to the connecting ropes up and down.
[0008] Preferably, a sliding plate is fixedly installed at the lower end of the second fixed rod. A sliding groove is provided on the side of the sliding plate near the lifting platform. The sliding groove matches the lifting platform. When we need to move the lifting platform, the lifting platform slides in the sliding groove to keep it stable.
[0009] Preferably, the electric hoist device includes a rotary motor, a connecting plate is fixedly installed on the drive end of the rotary motor, and an electric hoist is fixedly installed on the other end of the connecting plate. The electric hoist is fixedly connected to the connecting rope. When we need to move the lifting platform, we start the rotary motor to drive the electric hoist to retract and extend the connecting rope, thereby completing the lifting and lowering of the lifting platform.
[0010] Preferably, the lifting platform includes an operating platform, with a guardrail fixedly installed at the upper end of the operating platform. A safety door is hinged to one side of the guardrail, and a latch is fixedly installed on the outer side of the safety door. A storage box is fixedly installed on the side of the guardrail near the support plate, and a T-shaped block is fixedly installed on the side of the storage box near the support plate. The T-shaped block matches a T-slot. Multiple sets of stabilizing blocks are fixedly installed on the side of the guardrail near the support plate, and stabilizing rods are fixedly installed on the side of the stabilizing blocks near the support plate. The stabilizing blocks are slidably connected to the guardrail, and the stabilizing rods are located at the lower end of the storage box. When the lifting platform needs to be moved, the operating platform is moved up and down by pulling the connecting rope. The stability of the operating platform is protected by the stabilizing blocks and stabilizing rods, and the stability of the operating platform is improved by the sliding of the storage box on the support plate. At the same time, the storage box is used to place tools for installing the central integrated air conditioner, greatly increasing the convenience of installation.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0012] This utility model proposes a lifting structure for installing a central integrated air conditioner. In the initial state, the clip and rod are located at the upper end of the moving plate and at a 90-degree right angle to the square hole two. The fixing rod one is away from the square groove one. The upper half of the fixing rod one is located at the upper end of the moving plate, and the lower half of the fixing rod one is located inside the square hole one, without passing through the rotating shaft. The roller can rotate in multiple directions to adjust the direction and position of the moving plate. When we need to fix the moving platform, we rotate the connecting rod one to drive the clip and rod to rotate synchronously. When the clip and rod rotate to the matching position with the square hole two, the fixing rod one passes through the rotating shaft and the U-shaped connecting plate and falls into the square groove. The clip and rod fall into the square hole two for fixation. The fixing rod one completes the fixation of the rotating shaft, the U-shaped connecting plate and the roller, thereby completing the fixation of the moving platform. Attached Figure Description

The U-shaped connecting plate 136 is fixedly connected to rotating shaft 135. The inner side of U-shaped connecting plate 136 rotates. The roller 137 is equipped with a set of square grooves 138 on its upper end. The square grooves 138 match the fixing rod 134. The fixing rod 134 passes through the U-shaped connecting plate 136 and slides through it. In the initial state, the locking rod 133 is located at the upper end of the moving plate 11 and is at a 90-degree right angle to the square hole 113.

The upper half of the fixing rod 134 is located at the upper end of the moving plate 11, and the lower half of the fixing rod 134 is located inside the square hole 112 and does not pass through the rotating shaft 135. The roller 137 can move in multiple directions. Rotation adjusts the direction and position of the moving plate 11. When the moving platform 1 needs to be fixed, the connecting rod 131 is rotated to drive the clip and rod 133 to rotate synchronously. When the clip and rod 133 and the square hole 113 rotate to the matching position, the fixing rod 134 passes through the rotating shaft 135 and the U-shaped connecting plate 136 and falls into the square groove 138. The clip and rod 133 falls into the square hole 113 for fixing. The fixing rod 134 completes the fixing of the rotating shaft 135, the U-shaped connecting plate 136 and the roller 137, thereby completing the fixing of the moving platform 1.

A limit plate 232 is fixedly installed at the upper end of the T-slots 231. The T-slots 231 match the lifting platform 3. Two sets of connecting rods 25 are fixedly installed at the lower end of the second fixed rod 21. The connecting ropes 221 pass through the connecting rods 25 and are fixedly connected to the lifting platform 3. When we need to move the lifting platform 3, we retract the connecting ropes 221 by starting the electric hoist device 22, and move the lifting platform 3 connected to the connecting ropes 221 up and down.
[0027] Combination Figure 6 A sliding plate 24 is fixedly installed at the lower end of the fixed rod 21. A sliding groove 241 is provided on the side of the sliding plate 24 near the lifting platform 3. The sliding groove 241 matches the lifting platform 3. When we need to move the lifting platform 3, the lifting platform 3 slides in the sliding groove 241 to keep it stable.
[0028] Combination Figure 6 and Figure 7 The electric hoist device 22 includes a rotary motor 222. A connecting plate 223 is fixedly installed on the drive end of the rotary motor 222. An electric hoist 224 is fixedly installed on the other end of the connecting plate 223. The electric hoist 224 is fixedly connected to the connecting rope 221. When we need to move the lifting platform 3, we start the rotary motor 222 to drive the electric hoist 224 to retract and extend the connecting rope 221, thereby completing the lifting and lowering of the lifting platform 3.
[0029] Combination Figure 6 and Figure 8The lifting platform 3 includes an operating platform 31. A guardrail 32 is fixedly installed on the upper end of the operating platform 31. A safety door 33 is hinged to one side of the guardrail 32. A latch 34 is fixedly installed on the outer side of the safety door 33. A storage box 35 is fixedly installed on the side of the guardrail 32 near the support plate 23. A T-shaped block 351 is fixedly installed on the side of the storage box 35 near the support plate 23. The T-shaped block 351 matches the T-slot 231. Multiple sets of stabilizing blocks 36 are fixedly installed on the side of the guardrail 32 near the support plate 23. A stabilizing rod 37 is fixedly installed on one side, and a stabilizing block 36 is slidably connected to the guardrail 32. The stabilizing rod 37 is located at the lower end of the storage box 35. When we need to move the lifting platform 3, we pull the operating platform 31 up and down by connecting rope 221. The stability of the operating platform 31 is protected by the stabilizing block 36 and the stabilizing rod 37. The stability of the operating platform 31 is improved by sliding the storage box 35 on the support plate 23. At the same time, the tools for installing the central integrated air conditioner are placed in the storage box 35, which greatly increases the convenience of installation.
[0030] Working principle: By pushing the push rod 12, the direction and position of the moving plate 11, i.e., the moving platform 1, are changed. When not in use, the square groove 111 at the upper end of the moving plate 11 fixes the operating table 31, i.e., the lifting platform 3. When movement is required, the connecting rod 131 is rotated to make the clip and rod 133 rotate to match the square hole 113. The fixing rod 134 falls into the square groove 138, and the clip and rod 133 fall into the square hole 113, thus fixing the moving platform 1. The rotating motor 222 in the electric hoist device 22 is started, which drives the electric hoist 224 to retract and extend the connecting rope 221. The connecting rope 221 pulls the operating table 31, i.e., the lifting platform 3, up and down. At the same time, the T-shaped block 351 on the lifting platform 3 slides in the T-shaped groove 231 of the support plate 23, and the stabilizing block 36, the stabilizing rod 37, and the storage box 35 are on the support plate 23. The upward sliding motion together enhances the stability of the control panel 31.
