[0024] like Figure 1 As shown, the support 1 further includes wheels 8, the bottom of the support 1 is rotatably connected to the wheels 8, and the two wheels 8 are symmetrically distributed on the left and right.

[0025] like Figure 1 As shown, it also includes a hydraulic cylinder 2 and a support plate 3. The hydraulic cylinder 2 is bolted to the side of the bottom of the two brackets 1 that is away from each other. The two hydraulic cylinders 2 are symmetrically distributed on the left and right. The support plate 3 is fixedly connected to the telescopic rod of the hydraulic cylinder 2, and the bottom of the support plate 3 is in contact with the ground.

[0026] like Figure 1As shown, an anti-skid pad 31 is also included, and the bottom of the support plate 3 is fixedly connected to the anti-skid pad 31.

[0027] like Figure 4-Figure 6 As shown, it also includes a connecting plate 6, a clamping block 61 and a first spring 62. The bracket 1 has tooth grooves 104 symmetrically opened at even intervals on the front and rear sides. The two brackets 1 are slidably connected with a connecting plate 6. The sides of the connecting plate 6 that are away from each other on the front and rear sides are symmetrically slidably connected on the left and right sides. The first spring 62 is fixedly connected between the clamping block 61 and the connecting plate 6. The inclined surface of the clamping block 61 contacts the inclined surfaces of the upper and lower tooth grooves 104 on the same side.

[0028] like Figure 7 As shown, it also includes a pushing frame 7 and a second spring 71. The pushing frame 7 is symmetrically slidably connected to the bracket 1 front and back, and the second spring 71 is fixedly connected between the sides of the upper parts of the two pushing frames 7 that are close to each other. The lower part of the pushing frame 7 is located between the tooth grooves 104 on the upper and lower sides, and the lower part of the pushing frame 7 is in contact with the block 61.

[0029] Initially, the telescopic rod of the hydraulic cylinder 2 is in a retracted state, the bottom of the support plate 3 is higher than the bottom of the wheel 8, the right side of the locking piece 102 contacts the engaging portion of the limiting piece 103, and the left side of the locking piece 102 is located at the lower part of the guide rod 101, so that the right side of the locking piece 102 is engaged with the limiting piece 103, thereby locking the two brackets 1, and the inner wall of the bracket 1 contacts the block 61, and the first spring 62 is compressed, so that the block 61 is embedded in the connecting plate 6.

[0030] When it is necessary to install and lift the central air-conditioning duct unit, the bracket 1 is pushed to move, and the bracket 1 and its upper parts are conveniently moved to the working area where they need to be used through the wheels 8; when it is necessary to adjust the distance between the two support blocks 5, the locking piece 102 is pulled upward, and the locking piece 102 moves upward along the guide rod 101, so that the right side of the locking piece 102 is out of contact with the engaging part of the limit piece 103, and then the locking piece 102 is rotated counterclockwise to rotate the locking piece 102 around the guide rod 101, and the right side of the locking piece 102 is separated from the limit piece 103, thereby releasing the lock of the two brackets 1, and then the two brackets 1 are pulled to move away from each other, and under the guiding action of the connecting plate 6, the two brackets 1 are always When the bracket 1 is in the same straight line, the inner wall of the bracket 1 is out of contact with the block 61, and under the elastic force of the first spring 62, the block 61 is driven to move to the side away from the connecting plate 6. During this process, when the inclined surface of the tooth groove 104 contacts the inclined surface of the block 61, the block 61 is squeezed to move to the side close to the connecting plate 6, and the first spring 62 is compressed. When the inclined surface of the tooth groove 104 is out of contact with the inclined surface of the block 61, under the elastic force of the first spring 62, the block 61 is driven to move to the side away from the connecting plate 6 and reset and snap into the corresponding tooth groove 104, thereby limiting the bracket 1 and effectively preventing the two brackets 1 from moving and resetting until the two support blocks 5 move to a suitable spacing.

[0031] Then, the telescopic rods of the two hydraulic cylinders 2 are synchronously controlled to extend, driving the support plate 3 to drive the anti-skid pad 31 to move downward until the anti-skid pad 31 contacts the ground, and the friction between the anti-skid pad 31 and the ground is increased to improve stability. Subsequently, the telescopic rods of the hydraulic cylinders 2 continue to extend, driving the bracket 1 and its upper components to move upward until the wheels 8 are out of contact with the ground, thereby fixing the bracket 1 to prevent the bracket 1 from moving and affecting the installation effect, thereby improving the safety of use, and then placing the central air-conditioning duct unit to be installed between the tops of the two support blocks 5, and then synchronously controlling the two bidirectional screws 51 to rotate, and under the guiding action of the guide rod 53, driving the limit plate 52 to move to the side close to each other until the two The limit plates 52 are in contact with both sides of the central air-conditioning duct unit, thereby limiting the central air-conditioning duct unit, and then, the telescopic rods of the two cylinders 4 are synchronously controlled to extend, driving the support block 5 and its upper components to move upward, thereby lifting the central air-conditioning duct unit until it is lifted to a corresponding height position, and then the two bidirectional screws 51 are synchronously controlled to reverse, driving the limit plates 52 to move to the side away from each other, so that the limit plates 52 are out of contact with the central air-conditioning duct unit, thereby releasing the limit on the central air-conditioning duct unit, and then the central air-conditioning duct unit can be installed; in this way, the central air-conditioning duct unit can be safely and stably lifted to the corresponding installation position, which is easy to operate, saves time and effort, and has high safety in use.

[0032] If the height lifted by the cylinder 4 is not enough to meet the required installation height, the telescopic rods of the two hydraulic cylinders 2 can be further extended to drive the bracket 1 and its upper parts to move upward, so as to continue to lift the central air conditioning duct unit, thereby increasing the height position that the lifting device can lift.

[0033] After the installation is completed, the telescopic rods of the two air cylinders 4 are synchronously controlled to shorten, driving the support block 5 and its upper parts to move downward and reset, and then the telescopic rods of the two hydraulic cylinders 2 are synchronously controlled to shorten, driving the bracket 1 and its upper parts to move downward and reset until the wheels 8 contact the ground, and then the telescopic rods of the two hydraulic cylinders 2 are controlled to continue to shorten, driving the support plate 3 to drive the anti-skid pad 31 to move upward and reset, and the anti-skid pad 31 is out of contact with the ground, thereby releasing the fixation of the bracket 1, and then pulling the pushing frame 7 on the same bracket 1 to move to the side close to each other, the second spring 71 is compressed, and the lower part of the pushing frame 7 contacts the block 61, squeezing the block 61 to the side close to the connecting plate 6. Move, the first spring 62 is compressed, the block 61 is disengaged from the tooth groove 104, thereby releasing the limit on the bracket 1, and then pulling the pushing frames 7 on the left and right sides to move toward the side close to each other, so that the two brackets 1 and their upper parts are moved toward the side close to each other and reset until the two brackets 1 contact each other, and then rotate the locking piece 102 clockwise to make the right side of the locking piece 102 located on the upper side of the limiting piece 103, and then push the locking piece 102 downward to make the right side of the locking piece 102 contact with the engaging part of the limiting piece 103, thereby re-locking the two brackets 1; then repeat the above steps as needed, and the central air conditioning duct unit can be installed and lifted in the next work area.

[0034] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
