Description

Technical Field

[0001] The invention relates to the technical field of building electromechanical equipment, and in particular to a device for installing and fixing building electromechanical equipment. Background Art

[0002] Building electromechanical engineering is an important part of construction engineering, mainly including water supply and drainage system, power supply system, air conditioning and ventilation system, weak current system, fire protection system and intelligent system. In construction engineering, only by doing a good job in the technical management of electromechanical equipment installation engineering can the construction quality and progress of the project be controlled. The quality of electromechanical engineering directly affects the overall quality of the construction project, including the operation effect, energy saving and whether the building is practical when it is actually put into use. The quality of construction will determine the quality of building use.

[0003] The mechanical and electrical installation and fixing devices of buildings include the movement and fixation of central air conditioners during installation. However, with the increase in office buildings, in order to create a comfortable office environment, central air conditioners are usually installed on each floor. The central air conditioner outdoor unit is larger than the ordinary air conditioner outdoor unit. When the central air conditioner outdoor unit is installed on each floor, a dedicated air conditioner outdoor unit room is usually set up. After the central air conditioner is installed, the construction of the internal partition wall of the flat floor is carried out; the central air conditioner outdoor unit is large in size, and is usually lifted to the designated floor by a crane during installation, and then the installation technician moves the central air conditioner outdoor unit from the lifting site to the air conditioner outdoor unit room for installation. In large office spaces, the distance between the two is often far, and the central air conditioner is extremely inconvenient to move and move, and it is more labor-intensive when multiple units are installed. If a ground bull is used for towing, on the one hand, because the ground is often uneven when the building is constructed, the tugboat has a small tugboat, and the central air conditioner outdoor unit is bumpy when moved, which is easy to damage; on the other hand, even if a ground bull is used to move it to the installation site, since the central air conditioner needs to be installed on a base with a certain height, the ground bull cannot be easily positioned and installed on the base using a ground bull. In view of the above, we propose a building electromechanical equipment installation and fixing device to solve the above problems. Summary of the invention

In addition, the terms "first" and "second" are used only for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, unless otherwise specified, "multiple" means two or more. In addition, the term "including" and any variation thereof are intended to cover non-exclusive inclusions.

[0040] like Figure 1As shown, a building electromechanical equipment installation and fixing device includes a track frame structure 1, a mobile drive structure 2, and an external unit fixing frame 3; the track frame structure 1 includes a track body 4, the mobile drive structure 2 is arranged on the track body 4 and can move along the track body 4, the external unit fixing frame 3 is connected to the lower side of the mobile drive structure 2, and in actual use, the track body 4 can be connected end to end in multiple sections to increase, so that the track frame structure 1 is laid from a hoisting site to an installation site, and the track frame structure 1 also includes a plurality of gantries, and the track body 4 is erected between the plurality of gantries to maintain the stability of the track body 4, and a universal wheel is provided at the bottom of the gantry, so as to facilitate the adjustment of the direction of track laying and the installation of multiple air-conditioning external units.

[0041] like Figure 2 , Figure 3 As shown, the external unit fixing frame 3 includes a telescopic portion 5, an inverted U-shaped connecting frame 6, and a pivoted C-shaped frame. The telescopic portion 5 is fixedly connected to the mobile driving structure 2. The length of the telescopic portion 5 is adjusted to control the lifting of the external unit fixing frame 3 at the bottom as a whole. When the air-conditioning external unit is moved above the mounting base, it is convenient to place the air-conditioning external unit on the base. The free end of the telescopic portion 5 is provided with a rotating joint 7, and the rotating joint 7 is rotatably connected to the telescopic portion 5. The rotating joint 7 can make the pivoted C-shaped frame on the lower side rotate and adjust in the horizontal direction; the middle part of the connecting frame 6 is provided with a hinge seat 8, and the hinge seat 8 is hingedly connected to the lower end of the rotating joint 7. The setting of the hinge seat 8 can realize the connection frame 6 with the hinge seat 8 is the angle adjustment in the vertical direction of the axis; the pivoted C-shaped frame includes a frame body 1 9 and a frame body 2 10, both frames have a horizontally arranged cross frame, and the lower sides of the two ends of the cross frame are connected with longitudinal frames, frame body 1 9 and frame body 2 10 are hingedly connected through the midpoint of the cross frame, and the two ends of frame body 1 9 are hingedly connected to the two ends of the connecting frame 6, and frame body 2 10 can fix air conditioner outdoor units of different sizes when it is rotated relative to frame body 1 9. When in use, due to slight differences in the sizes of the air conditioner outdoor units, it is not convenient to fix them firmly when fixing the frame of the fixed structure. The pivoted C-shaped frame of the device can be rotated and adjusted through the frame body 1 9 and frame body 2 10 pivoted in the middle. Before installing the air conditioner outdoor unit, the two frames are overlapped as much as possible, such as Fig.13 As shown in the stereoscopic view of (a), the air conditioner outdoor unit can be moved into the opening of the two frames by using a ground cow over a short distance, and then the frame 10 is rotated. Fig.13As shown in the top view in (b), the two frames can firmly clamp the air-conditioning outdoor unit from four directions. In actual use, after the frame 1 9 and the frame 2 10 clamp the air-conditioning outdoor unit, in order to prevent the frame 2 10 from rotating at will, a strap can be used to tie the frame 1 9 and the frame 2 10 to fix them, or a limiting structure can be set between the frame 1 9 and the frame 2 10 to limit the two, so as to prevent the frame 1 9 and the frame 2 10 from rotating after the air-conditioning outdoor unit is fixed and causing the air-conditioning outdoor unit to fall. The lower ends of the four vertical frames are provided with a supporting frame structure 11 for supporting the air-conditioning outdoor unit; after the air conditioner is transported to the frame 1 9 and the frame 2 10 and clamped and fixed, its bottom is lifted by the supporting frame structure 11.

[0042] like Figure 3 , Fig. 9 , Fig.10 As shown, the support frame structure 11 includes a rotating foot 34 and a plug board 35. The rotating foot 34 is rotatably connected to the bottom of the four vertical frames. It can be understood that the shape of the vertical frames and the rotating foot 34 is not limited to the rectangular shape in the figure, and their cross-section can also be set to a circular shape. The rotating foot 34 is hollow inside and has an inner cavity 36 for accommodating the plug board 35. A fixed shaft 37 is horizontally provided at the bottom of the rotating foot 34. A waist hole 38 is penetrated through the side wall of the plug board 35. The plug-in and unplugging are connected to the fixed shaft 37 through the waist hole 38. A bayonet 39 is provided at the bottom of the rotating foot 34 for clamping the plug board 35. When in use, the plug board 35 can be as shown in FIG. Fig.10 The inner cavity 36 is inserted into the inner cavity 36 for storage, and magnets are provided on the top of the inner cavity 36 and the end of the plug plate 35 so that the plug plate 35 can be magnetically attracted to fix it. Fig.10 As shown, the plug plate 35 is pulled out downward, and when the upper end of the waist hole 38 moves down to the fixed shaft 37, the plug plate 35 is rotated to a horizontal state and then inserted horizontally into the bottom of the air-conditioning outdoor unit for support. At this time, the bayonet 39 can clamp the side of the plug plate 35 to limit it. Another advantage of this structure is that when the air-conditioning outdoor unit is installed on the base and falls down, it is only necessary to pull out the plug plate 35 horizontally to release the fixation of the air-conditioning outdoor unit, without moving the frame 1 9 or the frame 2 10.

[0043] like Figure 4 , Figure 5 , Fig.12As shown, the mobile driving structure 2 includes a shell 12, a driving part, a driven part, and an intermediate transmission part. The cross section of the track body 4 is an I-shaped structure. The upper two sides of the shell 12 are provided with buckle edges embedded in the two sides of the track body 4. A plurality of rollers 33 are rotatably connected on the buckle edges. The shell 12 is slidably connected to the track body 4 through the rollers 33. The driving gear part includes two mutually meshing driving gears 13 arranged on one side of the inside of the shell 12, and the driven part is two non-meshing driven gears 14 arranged on the other side of the shell 12, and the two driving gears 13 are symmetrically arranged coaxially with the rotating shafts of the two driven gears 14; a rack 25 is provided at the bottom of the track body 4, and the two driven gears 14 are respectively meshed with the rack 25. The driving structure also includes a reduction motor 18, which is fixed on the outside of the shell 12; when in use, the technician controls the reduction motor 18 to operate, and drives a driving gear 13 to rotate through the sprocket chain 19. Since the two driving gears 13 mesh with each other, so the rotation directions of the two driving gears 13 are different, and the intermediate transmission part is used to enable a driving gear 13 to transmit with the corresponding driven gear 14. Therefore, when one group of driving gears 13 and driven gears 14 are transmitting, the other group is disengaged from each other. At this time, the group of driven gears has one rotation direction; when the intermediate transmission part is adjusted to make another group of driving gears 13 and driven gears 14 rotate, the other driven gear 14 rotates in the opposite direction to the previous driven gear 14. Since the two driven gears 14 are meshed with the rack 25, the intermediate transmission part controls the mobile driving structure 2 to achieve reversing movement.

[0044] Specifically, Figure 4 , Figure 6 , Fig.12 As shown, the intermediate transmission part includes a fixed surface ratchet gear 15, a sliding surface ratchet gear 16 and a fork structure 17 for moving the sliding surface ratchet gear 16, wherein the fixed surface ratchet gear 15 is provided with two fixedly connected to one side of the two driven gears 14 respectively, and the sliding surface ratchet gear 16 is provided with two rotating shafts respectively slidably connected to the two driving gears 13, and the fork structure 17 is used to move the sliding surface ratchet gear 16 along the axial direction of the rotating shaft of the driving gear 13, and the sliding surface ratchet gear 16 can slide and move along the axial direction of the driving gear 13, and the rotating shaft of the driving gear 13 is moved toward A bar key is provided on the side wall protruding toward the end of the driven gear 14, and the sliding surface ratchet gear 16 has a key groove on the inner wall that matches the bar key; the sliding surface ratchet gear and the fixed surface ratchet gear 15 are divided into two groups and arranged opposite to each other, and the fork structure 17 is arranged between the two sliding surface ratchet gears. The fork structure 17 is rotatably connected to the housing 12, and the rotation of the fork structure 17 can switch the engagement and separation of different groups of sliding surface ratchet gears and fixed surface ratchet gears 15, that is, when the fork structure 17 is rotated and adjusted, one group of surface ratchet gears is engaged, and the other group of surface ratchet gears is disengaged synchronously.

[0045] like Figure 7As shown, the fork structure 17 includes a fork plate 20, a central axis 21 is fixedly provided in the middle of the fork plate 20, and the fork structure 17 is rotatably connected to the housing 12 through the central axis 21. The fork plate 20 has openings on both sides for accommodating the sliding surface ratchet gear, and the upper and lower side surfaces in the opening are rotatably connected with shift blocks 22, and the sliding surface ratchet gear is provided with an annular groove 23 that matches the shift block 22. The side wall of the central axis 21 is vertically provided with a shift rod 24, and the shift rod 24 is used to drive the rotation of the entire fork structure 17. When the shift rod 24 rotates, the shift blocks 22 hinged on both sides simultaneously shift the two sliding surface ratchet gears 16 on both sides to achieve the shifting operation. Fig.11 As shown, a tension spring is provided between the inner wall of the shell 12 and the end of the fork structure. When the fork plate 20 and the shift rod 24 are deflected, the tension spring can tighten the shift rod 24, thereby ensuring that the fixed surface ratchet gear 15 and the sliding surface ratchet gear 16 that are meshed with each other always maintain a good meshing state when the mobile driving structure 2 moves.

[0046] like Figure 1 As shown, the two ends of the bottom of the track body 4 are fixed with blocking rods 26. When multiple track bodies 4 are connected, the blocking rods 26 are arranged at the head and tail ends of the multiple connected track bodies 4. In order to ensure the safety of the movement of the air-conditioning outdoor unit and to prevent the entire mobile driving structure 2 from being accidentally operated to disengage the air-conditioning outdoor unit fixed on the lower side from the track body 4 when the mobile driving structure 2 moves to the end of the track body 4, the blocking rods 26 can enter the housing 12 from both ends when the mobile driving structure 2 moves to the end of the track body 4. Since the mobile driving structure 2 moves toward the blocking rod 26, the blocking rod 26 can move the lever 24, so that the plug-in structure rotates to perform a passive gear shifting operation. After the gear shifting, the mobile driving structure 2 moves in the opposite direction along the track body 4 to avoid the risk of falling off the track.

[0047] Furthermore, in order to reduce the overall shaking of the air conditioner outdoor unit when the air conditioner outdoor unit moves, Figure 8As shown, a locking structure is provided between the upper side of the horizontal frame of the frame body 9 and the connecting frame 6, and the locking structure includes a vertical plate 27, a latch 28, a spring 29, and a pin hole 30; the pin hole 30 is provided on the connecting frame 6, and the vertical plate 27 is provided with two and is fixedly provided at a certain distance on the horizontal frame at one end close to the pin hole 30, and a latch 28 is provided through the two vertical plates 27 for sliding connection, and the latch 28 can be inserted into the pin hole 30 to fix the frame body 9 and the connecting frame 6, and a push plate 32 is also fixed on the latch 28, and the push plate 32 is located between the two vertical plates 27, and a spring 29 is provided between the push plate 32 and the vertical plate 27 on the side away from the pin hole 30. A key 31 is provided along the protrusion of the side wall of the latch 28, and a notch matching the key 31 is provided on the vertical plate 27 on the side away from the pin hole 30. The latch 28 can be positioned by pulling the latch 28 to make the key 31 rotate out of the notch. When the connecting frame 6 and the frame body 9 need to be fixed during movement, the key 31 is slid into the notch, and the latch 28 can be inserted into the pin hole 30 for fixation under the action of the spring 29 pushing the push plate 32. Conversely, the latch 28 is pulled out, and when the key 31 leaves the notch, the latch 28 is rotated to make the key 31 misaligned with the notch, so that the latch 28 cannot be inserted into the pin hole 30, and the frame body 9 can rotate relative to the connecting frame 6.

[0048] The present invention and its implementation methods are described above, and such description is not restrictive. The specific implementation methods are only part of the embodiments of the present invention, not all of the embodiments, and the actual structure is not limited thereto. In short, if ordinary technicians in the field are inspired by it, without departing from the purpose of the invention, they can design a structure and implementation method similar to the technical solution without creativity, which should fall within the protection scope of the present invention.
