Description

Technical Field

[0001] This utility model relates to the field of electromechanical installation technology, specifically an adjustable bracket for electromechanical installation in buildings. Background Technology

[0002] Mechanical and electrical equipment generally refers to equipment that includes both mechanical and electrical components, such as motors, pumps, fans, and conveyors. When installing mechanical and electrical equipment in a building, some of the equipment is located in a small indoor space, making it inconvenient to hoist the equipment in. In such cases, installation is usually done manually using ladders and other tools. For example, in small equipment rooms where other equipment is densely packed, the installation and replacement of ventilation fans and air conditioning units usually require manual handling to move them to a suitable height before installation. The installation process is inconvenient because the equipment needs to be supported. Alternatively, some equipment may be lightweight, but its outer casing may have protruding edges due to design or manufacturing reasons, making it difficult for personnel to handle.

[0003] Furthermore, some buildings, such as factories, have complex staircase layouts. Some staircases may require the installation or replacement of electromechanical equipment such as cameras and sensors. Generally, ladders are not suitable for placement on stair treads, as this is quite inconvenient. Utility Model Content

[0004] The purpose of this utility model is to provide an adjustable bracket for electromechanical installation in buildings to solve the problems mentioned in the background art.

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

Detailed Implementation

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

[0024] Please see Figures 1-5 In this embodiment of the utility model, an adjustable bracket for building electromechanical installation includes:

[0025] The system comprises a housing 100, an A-frame ladder 200, a lifting mechanism 300 for lifting electromechanical equipment, and a support mechanism 400 for supporting the electromechanical equipment. Multiple casters are fixedly connected to the bottom surface of the housing 100. The two bottom ends of the A-frame ladder 200 are located at opposite ends of the bottom surface of the housing 100. The lifting mechanism 300 is located at the top of the A-frame ladder 200 and includes a U-shaped frame 310. The two arms of the U-shaped frame 310 are fixedly connected to the top ends of opposite sides of the A-frame ladder 200. On both sides of the U-shaped frame 310, there are ring bodies 311. Support arms 312 are fixedly connected to the outer walls of the two ring bodies 311. One end of the two support arms 312 is rotatably connected to the opposite side of the two arms of the U-shaped frame 310. Pull ropes 320 are provided on both sides of the ladder 200. One end of the two pull ropes 320 is fixedly connected to the lifting rods 340, and the other end passes through the inside of the adjacent ring body 311 and through the bottom surface of the adjacent lifting rods 340. The support mechanism 400 is fixedly connected to the two lifting rods 340.

[0026] Specifically, the two lifting rods 340 have through holes. By placing the A-frame ladder 200 inside the box 100, and then passing one end of each of the two pull ropes 320 through the inside of the two rings 311 and then through the through holes on the adjacent lifting rods 340, the electromechanical equipment to be installed on the wall, such as an indoor air conditioner unit, is placed on the bracket mechanism 400. Then, by pulling one end of each of the two pull ropes 320, the bracket mechanism 400 and the electromechanical equipment can be moved upward together. Then, the user can climb the A-frame ladder 200 to manually install the electromechanical equipment, so that the user does not need to manually move the equipment. The height of the bracket mechanism 400 and the electromechanical equipment can be fixed by fixing the pull ropes 320, which facilitates the installation by the user. The A-frame ladder 200 can be removed from the box 100 and stored separately. In the prior art, there are also foldable A-frame ladders 200 that can be folded and stored, which makes storage convenient and takes up less space when stored. The casters on the bottom of the box 100 all have a self-locking structure to fix their position.

[0027] Example 1

[0028] like Figures 1-2 As shown, in this embodiment, a drive box 330 is fixedly connected to the center of the bottom surface of the box 100, and two automatic winches are provided inside the drive box 330. The other ends of the two pull ropes 320 are respectively fixedly wound on the reels of the two automatic winches.

[0029] In this embodiment, by activating two automatic winches, two pull ropes 320 can be automatically wound up, driving two lifting rods 340 and the support mechanism 400 to move upward. This allows the user to control the height of the two lifting rods 340 by controlling the automatic winches when working on the A-frame ladder 200. The automatic winches in the drive box 330 are equipped with a relay gearbox. A signal can be sent to the relay gearbox via a remote control, causing the relay gearbox to receive the signal from the remote control and change the overall circuit of the motor direction and the start and stop of the motor. This allows for remote control technology, which is existing technology and will not be described in detail here.

[0030] like Figure 4 As shown, in this embodiment, the support mechanism 400 includes:

[0031] The support frame 410 and the counterweight frame 420 are located on one side of the A-frame ladder 200. One side of the support frame 410 is fixedly connected to one end of the two lifting rods 340. The counterweight frame 420 is located on the other side of the A-frame ladder 200. One side of the counterweight frame 420 is fixedly connected to the other end of the two lifting rods 340. The counterweight frame 420 is arc-shaped.

[0032] In practice, when using the equipment, the user can lean the support frame 410 against the wall, place the electromechanical equipment on the support frame 410, place the tools used for installation on the counterweight frame 420, and place a certain weight on the counterweight frame 420 so that the total weight of the items on the support frame 410 and the counterweight frame 420 is approximately the same. This causes the two lifting rods 340 to move upward, which in turn moves the support frame 410 and the counterweight frame 420 upward synchronously. The support frame 410 is not easy to tilt, thus moving the electromechanical equipment to a suitable position and making it easy for the user to retrieve tools from the counterweight frame 420. When the user climbs the A-frame ladder 200, because the counterweight frame 420 is curved, there is a certain space between the inner curved surface of the counterweight frame 420 and the A-frame ladder 200, which makes it easy for the user to stand on the A-frame ladder 200.

[0033] like Figures 2-4As shown, in this embodiment, positioning ropes 440 are provided on both opposite sides of the box body 100, and notches 101 are opened on both opposite sides of the box body 100. Fixing frames 443 are fixedly connected inside each of the two notches 101, and threaded holes are opened on one side of each of the two fixing frames 443. Fastening bolts are screwed into each of the two threaded holes, and nail plates 444 are rotatably connected to one end of each of the two fastening bolts. The bottom ends of the two positioning ropes 440 are respectively located inside the two fixing frames 443, and limit cylinders 430 are fixedly connected to one side of each of the two lifting rods 340. Furthermore, the inner walls of the two limiting cylinders 430 are slidably sleeved with the outer walls of the two positioning ropes 440 respectively. The top of each of the two positioning ropes 440 is fixedly connected to a connecting plate 441. The top surface of each of the two connecting plates 441 is provided with a circular hole, and a U-shaped rod 442 is provided above each of the two connecting plates 441. The outer walls of both arms of any U-shaped rod 442 are threaded. Both arms of any U-shaped rod 442 pass through the two circular holes on the adjacent connecting plate 441 and are screwed with nuts. The two U-shaped rods 442 are movably sleeved on the outer walls of the two support arms 312 respectively.

[0034] In practice, before placing the A-frame ladder 200 inside the box 100, two U-shaped rods 442 can be fitted onto the two support arms 312. Then, the two arms of the U-shaped rods 442 are passed through the circular holes on the adjacent connecting plates 441 and the nuts are tightened, so that the two U-shaped rods 442 are fitted onto the two support arms 312. Then, the two positioning ropes 440 are pulled taut and passed through the adjacent limiting cylinders 430 and the fixed frame 443. The nail plates 444 have spikes. Then, the two fastening bolts are turned to drive the two nail plates 444 to press the adjacent positioning ropes 440 against the adjacent fixed frame 443. On the wall, the spikes on the nail plate 444 are driven into the positioning rope 440 to fix the positioning rope 440 for a second time, so that the positioning rope 440 is kept taut. When the weight of the object on the counterweight frame 420 is insufficient, the length of the limiting cylinder 430 is relatively long. The limiting cylinder 430 can be used to fit on the positioning rope 440. The positioning rope 440 and the limiting cylinder 430 provide auxiliary support for the two lifting rods 340, so that the two lifting rods 340 are kept relatively parallel to the ground and ceiling, so that the two lifting rods 340 can move upward and the support frame 410 and the counterweight frame 420 are not easy to tilt.

[0035] Example 2

[0036] Based on Embodiment 1, four support plates 130 are provided to facilitate the adjustment of the box body 100 level.

[0037] like Figure 5 As shown, in this embodiment, two internally threaded cylinders 110 are fixedly connected to each other on both sides of the box body 100. Each internally threaded cylinder 110 has a screw 120 screwed inside, and each screw 120 has a support plate 130 rotatably connected to its bottom end.

[0038] In practice, during installation, after the casters are self-locked, the four screws 120 can be rotated to make the four support plates 130 contact the ground, improving the stability of the box 100. When installing electromechanical equipment on a staircase, the four screws 120 can be rotated to make the four support plates 130 lift the box 100. The length of the adjacent internal threaded cylinders 110 can be adjusted by rotating the screws 120 to adjust the height of the four corners of the box 100 so that the box 100 is in a horizontal state, thus adapting to the wall installation of equipment in buildings with different terrains.

[0039] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0040] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
