Description

Technical Field

[0001] The present invention relates to the technical field of indoor unit installation equipment, and more specifically, to an auxiliary installation equipment for a central air-conditioning indoor unit. Background Art

[0002] The 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 for the air conditioning system to offset the heat load of the indoor environment. When installing the central air-conditioning indoor unit, it is first necessary to locate and drill holes, and then install the lifting screws in the installation holes. At least two installers need to climb onto a folding stepladder to lift it to complete the installation. The installation efficiency is low and the installation risk is high.

[0003] The Chinese patent application number CN202010825120.0 discloses an auxiliary installation device for a central air-conditioning indoor unit, including a base plate, a lift and a lifting platform. The lifting platform includes a support plate at the bottom, a column sleeve is provided at the bottom of the support plate, a compression elastic member is provided in the column sleeve, a slewing bearing is sleeved on the column sleeve, the inner ring of the slewing bearing is fixedly sleeved on the outer periphery of the bottom of the column sleeve, and a rectangular turntable is sleeved on the rotating outer ring of the slewing bearing. The rectangular turntable includes a circular concave cavity opened at the center of the top, and a tooth groove is provided on the inner ring peripheral wall of the rectangular turntable. A rotating motor is provided at the bottom of the support plate, and a rotating gear is connected to the power output end of the rotating motor.

The laser ranging structure in the invented device has compact structure, low cost, convenient operation, time and labor saving, accurate measurement, and convenient maintenance, which can greatly improve the installation efficiency of the air-conditioning indoor unit. Although the auxiliary installation device for the air conditioner indoor unit will detect the distance to the wall through a laser rangefinder before lifting the air conditioner indoor unit, thus improving the installation accuracy and efficiency, if there is a size deviation between the lower wall and the upper wall, the deviation between the lifting screw and the installation hole of the air conditioner indoor unit cannot be completely avoided by detecting the distance to the wall, resulting in the inability to smoothly install and dock the air conditioner indoor unit.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] Embodiment 1

[0034] refer to Figure 1-Figure 3 An auxiliary installation device for a central air-conditioning indoor unit according to an embodiment of the present invention comprises a mounting plate 1 and a limiting device 2. The limiting device 2 is arranged above the mounting plate 1 and comprises an air storage box 201 fixedly connected to the top center position of the mounting plate 1. A partition plate 202 that moves up and down is slidably connected inside the air storage box 201. The interior of the air storage box 201 is divided into a first chamber 203 and a second chamber 204 of the same size by the partition plate 202. The limiting device 2 is used to use the weight of the air-conditioning indoor unit to squeeze the air inside the first chamber 203 and the second chamber 204 to clamp and limit the air-conditioning indoor unit.

[0035] refer to Figure 3 - Figure 5The limiting device 2 also includes a sealing cover 205, a sliding groove 206 is provided at the bottom of the sealing cover 205, the air storage box 201 and the partition plate 202 are both slidably connected in the sliding groove 206, and a first elastic member 223 is connected between the bottom of the first chamber 203 and the second chamber 204 and the sealing cover 205; the top of the mounting plate 1 is symmetrically fixedly connected with the third chamber 207 and the fourth chamber 208 on the left and right sides of the air storage box 201, and the top of the mounting plate 1 is symmetrically fixedly connected with the fifth chamber 209 and the sixth chamber 210 on the front and rear sides of the air storage box 201; the interior of the third chamber 207 is sealed and slidably connected with a first piston plate 211, and the first piston plate 211 is fixedly connected with a first piston rod 212 on one side close to the air storage box 201, and the other end of the first piston rod 212 extending out of the third chamber 207 is fixedly connected with a first limiting frame 213, and the interior of the fourth chamber 208 is sealed and slidably connected with a second piston plate 214, and the second piston plate A second piston rod 215 is fixedly connected to one side of 214 near the gas storage box 201, and a second limiting frame 216 is fixedly connected to the other end of the second piston rod 215 extending out of the fourth chamber 208; a third piston plate 217 is sealingly and slidably connected inside the fifth chamber 209, a third piston rod 218 is fixedly connected to one side of the third piston plate 217 near the gas storage box 201, and a third limiting frame 219 is fixedly connected to the other end of the third piston rod 218 extending out of the fifth chamber 209; a fourth piston plate 220 is sealingly and slidably connected inside the sixth chamber 210, a fourth piston rod 221 is fixedly connected to one side of the fourth piston plate 220 near the gas storage box 201, and a fourth limiting frame 222 is fixedly connected to the other end of the fourth piston rod 221 extending out of the sixth chamber 210; the first chamber 203 is communicated with the third chamber 207 and the fifth chamber 209 respectively, and the second chamber 204 is communicated with the fourth chamber 208 and the sixth chamber 210 respectively.

[0036] During actual use, the central air-conditioning indoor unit is placed on the top of the sealing cover 205. At this time, under the action of the gravity of the central air-conditioning indoor unit, the sealing cover 205 will compress the two first elastic members 223 and move downward under the limiting action of the air storage box 201. During the downward movement of the sealing cover 205, the air in the first chamber 203 and the second chamber 204 is squeezed by the sealing cover 205, and the air in the first chamber 203 will be squeezed into the third chamber 207 and the fifth chamber 209, and the air in the second chamber 204 will be squeezed into the fourth chamber 208 and the sixth chamber 210. At this time, the air in the third chamber 207 will push the first piston plate 211 to drive the first piston rod 212 and the first limiting frame 213 to move toward the direction of the air storage box 201, and the air in the fourth chamber 208 will push the second piston plate 214 to drive the second piston rod 215 and the second limiting frame 216 to move toward the direction of the air storage box 201, thereby automatically clamping and limiting the two sides of the central air-conditioning indoor unit.

[0037] At the same time, the air in the fifth chamber 209 will push the third piston plate 217 to drive the third piston rod 218 and the third limit frame 219 to move toward the air storage box 201, and the air in the sixth chamber 210 will push the fourth piston plate 220 to drive the fourth piston rod 221 and the fourth limit frame 222 to move toward the air storage box 201, thereby automatically clamping and limiting the two sides of the central air-conditioning indoor unit, thereby realizing clamping and limiting in four directions.

[0038] In summary, by setting the limit device 2 and utilizing the weight of the central air-conditioning indoor unit, the four directions of the central air-conditioning indoor unit can be automatically clamped and limited during the installation process, which can effectively prevent the central air-conditioning indoor unit from moving and falling during the installation process, avoid safety hazards caused by falling, and can be installed stably, thereby improving work efficiency.

[0039] Embodiment 2

[0040] During actual use, after the central air-conditioning indoor unit is lifted, the installation hole of the central air-conditioning indoor unit may deviate from the position of the pre-installed lifting screw, resulting in the inability to successfully install and dock the air-conditioning indoor unit. Other installers are required to move the entire device back and forth below to complete the adjustment. Multiple installers need to communicate constantly during the adjustment process to accurately adjust the installation angle and installation position of the air-conditioning indoor unit, which is rather troublesome and greatly affects the installation efficiency. Therefore, this embodiment improves the device described in the above embodiment.

[0041] refer to Figure 1-Figure 6 , and also includes an adjusting device 3, which is arranged below the mounting plate 1 and is used to unlock the mounting plate 1, control the partition plate 202 to move up and down, adjust the limit of the limit device 2, and realize the adjustment of the installation position and installation angle of the central air-conditioning indoor unit.

[0042] The adjusting device 3 includes a base plate 301, the center of the base plate 301 rotates and is penetrated by a rotating sleeve 302 connected to the mounting plate 1, a first hydraulic chuck 303 is provided on the base plate 301, a second hydraulic chuck 304 is provided at the bottom of the rotating sleeve 302, electric telescopic rods 305 are symmetrically provided at the bottom of the base plate 301, a support plate is provided between the electric telescopic rods 305, a motor 306 with an output shaft penetrating the support plate is provided on the support plate, a threaded rod 307 is fixedly connected to the output end of the motor 306, the threaded rod 307 penetrates the rotating sleeve 302 and the mounting plate 1, a threaded hole is opened on the partition plate 202, the threaded rod 307 is threadedly connected to the inside of the threaded hole, and the threaded rod 307 is rotatably connected to the mounting plate 1.

[0043] refer to Figure 1 and Figure 8A scissor-type lifting device 4 is installed at the bottom of the base plate 301. The scissor-type lifting device 4 is used to control the lifting of the adjusting device 3. The scissor-type lifting device 4 is a prior art and is not described in detail here. A plurality of universal wheels 401 are arranged at the bottom of the scissor-type lifting device 4, and the universal wheels 401 have a self-locking function; the adjusting device 3, the scissor-type lifting device 4 and the leveling device 5 are all electrically connected to an external controller. The scissor-type lifting device 4 and the universal wheels 401 are provided with a height adjustment device, and the height adjustment device can be a hydraulic telescopic lever or a screw rod.

[0044] In actual use, first, the installer uses a measuring tool to locate and drill holes at the appropriate position, and then installs the lifting screw in the installation hole. The installer then moves the device to the appropriate position and adjusts the levelness of the device using a horizontal measuring tool.

[0045] After the adjustment is completed, the installer locks the multiple universal wheels 401 to prevent the device from moving during the installation process, and then places the central air-conditioning indoor unit above the limit device 2 for clamping and limiting. After the placement is completed, the central air-conditioning indoor unit on the limit device 2 is driven to move upward by controlling the scissor-type lifting device 4, thereby completing the lifting of the central air-conditioning indoor unit.

[0046] When the central air-conditioning indoor unit is lifted up and there is position deviation and angle deviation between the installation hole and the ceiling bolt, the first hydraulic chuck 303 is controlled to release the jamming of the rotating sleeve 302, and the second hydraulic chuck 304 is controlled to jam the output shaft of the motor 306, and then the motor 306 is controlled to reverse, and the output end of the motor 306 will drive the second hydraulic chuck 304 and the rotating sleeve 302 to reverse, and the rotation of the rotating sleeve 302 drives the bottom plate 301 to adjust the angle of the central air-conditioning indoor unit. After the adjustment is completed, the second hydraulic chuck 304 is controlled to release the jamming of the output shaft of the motor 306, and the first hydraulic chuck 303 is controlled to jam the rotating sleeve 302. After the angle is adjusted, the mounting plate 1 is locked.

[0047] At the same time, during the reversal of the motor 306, the output end of the motor 306 will drive the threaded rod 307 to reverse, and during the reversal, the threaded rod 307 will drive the partition plate 202 to slide upward in the air storage box 201 and the slide groove 206 through the threaded hole, so that the first chamber 203 is connected to the second chamber 204. At this time, the third chamber 207, the fourth chamber 208, the fifth chamber 209, and the sixth chamber 210 can be connected to each other. The installer can adjust the position of the central air-conditioning indoor unit at this time. For example, when the position of the central air-conditioning indoor unit and the hanging bolt deviates to the right, the installer can adjust the position by pulling the central air-conditioning indoor unit to the left. Since the third chamber 207, the fourth chamber 208, the fifth chamber 209, and the sixth chamber 210 are in a connected state at this time, when the installer pulls the central air-conditioning indoor unit to move to the left, the left outer wall of the central air-conditioning indoor unit can push the first limit frame 213 to drive the first piston rod 212 and the third limit frame 213 to drive the first piston rod 212 and the sixth piston rod 212 to move to the left. A piston plate 211 moves to the left in the third chamber 207, so that the first piston plate 211 squeezes the air in the third chamber 207 into the first chamber 203 and the second chamber 204. Since the sealing cover 205 is squeezed by the central air-conditioning indoor unit at this time, the air in the third chamber 207 cannot lift the sealing cover 205 under the weight of the central air-conditioning indoor unit. At the same time, the third limit frame 219 and the fourth limit frame 222 are in a front and rear clamping limit state for the central air-conditioning indoor unit. The third limit frame 219 and the fourth limit frame 222 cannot move. Therefore, the air in the third chamber 207 will cause the second piston plate 214 to drive the second piston rod 215 and the second limit frame 216 to move to the left synchronously with the central air-conditioning indoor unit, so that the position of the central air-conditioning indoor unit can be adjusted. The installer controls the scissor lift 4 to rise, so that the installation hole of the central air-conditioning indoor unit is smoothly connected with the lifting bolt, which is convenient for the installer to complete the installation work.

[0048] Embodiment 3

[0049] During actual use, although the device plays a role of limiting and clamping when lifting the indoor unit of the central air-conditioning unit, after the lifting is completed and the limiting function of the device is lost, the lifting bolts may undergo plastic deformation, resulting in changes in the levelness of the central air-conditioning indoor unit. The installer is required to measure the levelness of the air-conditioning indoor unit back and forth with a measuring tool, and then complete the leveling work by turning the nuts on the four corners for multiple adjustments. This is rather troublesome and results in low installation efficiency of the indoor unit. At the same time, the staff needs to move back and forth during the leveling process, which greatly increases safety hazards. Therefore, this embodiment improves the device described in the above embodiment.

[0050] refer to Figure 1 , Figure 3 , Figure 7 and Figure 8 , and also includes a leveling device 5, which is arranged above the limiting device 2 and is used to perform horizontal detection and horizontal adjustment on the air-conditioning indoor unit after the air-conditioning indoor unit is installed; the leveling device 5 includes an adjustment chamber 501 opened on the upper part of the sealing cover 205, and at least four lifting holes 502 connected to the adjustment chamber 501 are opened on the top of the sealing cover 205. The four lifting holes 502 are distributed at the four corners of the top of the sealing cover 205, and each lifting hole 502 is slidably connected with a lifting column 503, and the bottom of each lifting column 503 is fixedly connected to a limiting block 504, A second elastic member 505 is connected between the bottom of each limit block 504 and the regulating chamber 501, a pressure sensor 506 is arranged on the top of each lifting column 503, an exhaust valve 507 connected to the regulating chamber 501 is provided on one side of the sealing cover 205, and a one-way air intake valve 508 is provided on the front and rear side walls of the slide groove 206 opposite to the partition plate 202 to allow gas to enter the slide groove 206 from the outside, and a one-way valve 509 connected to the slide groove 206 is provided in the middle of the regulating chamber 501, and the air flow direction of the one-way valve 509 is from the slide groove 206 to the regulating chamber 501.

[0051] During actual use, when the central air-conditioning indoor unit is placed above the limiting device 2 for clamping and limiting, the bottom of the central air-conditioning indoor unit will contact each pressure sensor 506 and compress the corresponding second elastic member 505 to squeeze each pressure sensor 506 and the corresponding lifting column 503 into the lifting hole 502 and the adjustment chamber 501.

[0052] After the installer completes the installation of the central air-conditioning indoor unit, he controls the scissor-type lifting device 4 to drive the limit device 2 to descend. At this time, the sealing cover 205 gradually moves upward under the rebound action of the two first elastic members 223, so that the gas in the third chamber 207, the fourth chamber 208, the fifth chamber 209 and the sixth chamber 210 is drawn back into the first chamber 203 and the second chamber 204, and further makes the first limit frame 213, the second limit frame 216, the third limit frame 219 and the fourth limit frame 222 gradually return to the initial position, thereby releasing the limit on the central air-conditioning indoor unit.

[0053] When the sealing cover 205 returns to the initial position and the scissor-type lifting device 4 continues to drive the limit device 2 to descend, the multiple lifting columns 503 and the multiple pressure sensors 506 gradually extend out from the lifting hole 502 under the rebound action of the corresponding second elastic member 505. When the central air-conditioning indoor unit loses the limit and there is a horizontal deviation, the central air-conditioning indoor unit will tilt slightly. At this time, the pressure sensor 506 located at the highest point of the inclination will first lose contact with the bottom of the central air-conditioning indoor unit, and the multiple pressure sensors 506 at the lower point of the inclination are still in contact with the bottom of the central air-conditioning indoor unit.

[0054] When the pressure sensor 506 detects that it has lost contact with the bottom of the central air-conditioning indoor unit, the corresponding pressure sensor 506 returns to the initial position under the rebound effect of the second elastic member 505. When the pressure sensor 506 that has lost contact with the bottom of the central air-conditioning indoor unit detects that the pressure disappears, the pressure sensor 506 feeds back the detection data to the controller. At this time, the controller controls the scissor lift device 4 to stop descending, and then controls the electric telescopic rod 305 to retract. The contraction of the electric telescopic rod 305 will drive the motor 306, the threaded rod 307 and the partition plate 2 02 slides up and finally moves to the sealing cover 205, thereby forming a support for the sealing cover 205. At the same time, during the upward movement, the gas in the slide groove 206 is filled into the regulating chamber 501, and then the motor 306 is controlled to repeatedly rotate forward and reverse, and the threaded rod 307 is used to drive the partition plate 202 to reciprocate downward and upward. When the partition plate 202 moves downward, the external air is sucked into the slide groove 206 from the one-way air intake valve 508. When moving upward, the air in the slide groove 206 is filled into the regulating chamber 501, thereby realizing the pressure replenishment of the regulating chamber 501.

[0055] Then, by replenishing pressure in the adjustment chamber 501, the pressure sensor 506 that has lost contact with the bottom of the central air-conditioning indoor unit cannot continue to move upward due to the action of the limit block 504, and multiple pressure sensors 506 that are in contact with the bottom of the central air-conditioning indoor unit gradually move upward under the action of pressure, applying thrust to the inclined position of the bottom of the central air-conditioning indoor unit. When each pressure sensor 506 returns to its initial position under the action of the thrust, the multiple pressure sensors 506 are in the same plane and remain in a horizontal state. At this time, the central air-conditioning indoor unit is also maintained in a horizontal state under the support of multiple horizontal pressure sensors 506. At this time, the installer can complete the horizontal adjustment and installation at one time by adjusting the nut.
