Description

Technical Field

[0001] This application relates to the field of auxiliary installation equipment for electromechanical modules, and in particular to a horizontal limiting device for an electromechanical module. Background Technology

[0002] Currently, with the increasing functionality of various buildings such as factories, office buildings, and residential buildings, the layout of fire protection, water supply, ventilation, and electrical equipment is becoming increasingly complex. In the installation of most electromechanical modules, each professional pipeline is designed and installed separately, which inevitably leads to pipeline elevation conflicts and pipeline intersections. In order to rationally arrange pipelines in limited space, large buildings use supports and hangers in public areas, integrating air ducts, fire protection pipes, and water supply pipes at different heights onto these supports and hangers.

[0003] Horizontal restraint of each pipe to ensure a seamless connection between pipes is a crucial issue in pipe installation engineering. A typical pipe support consists of two vertical rods and a horizontal bracket connecting them. The space between the two horizontal brackets is for duct installation, while the upper surface of the upper bracket is used for installing circular pipes such as fire-fighting pipes and water supply pipes. Although typical pipe supports usually have clamps of different sizes to restrain circular pipes of different diameters, space is often reserved on both sides to facilitate duct insertion, resulting in relatively poor duct restraint. Summary of the Invention

[0004] To improve the limiting effect on the air duct in the electromechanical module, this application provides a horizontal limiting device and limiting method for the electromechanical module.

[0005] The horizontal limiting device and limiting method for an electromechanical module provided in this application adopt the following technical solution:

[0006] On one hand, this application provides a horizontal limiting device for an electromechanical module, comprising:

[0007] The support frame body includes a vertical hanger, a first horizontal hanger and a second horizontal hanger connected between the two vertical hangers, and a space for installing air ducts is formed between the first horizontal hanger and the second horizontal hanger. Several pipe clamps of different specifications are installed on the upper surface of the second horizontal hanger.

[0008] The horizontal limiting assembly includes a support seat mounted on the first horizontal hanger and clamping members mounted on both ends of the support seat. The width between the two clamping members is the same as the width of the duct. The clamping members are used to keep the top surface of the support seat flush before the duct is installed in place, and to extend to clamp both sides of the duct after the duct is installed in place.

[0009] By adopting the above technical solution, during installation, the top surface of the clamping component remains flush with the top surface of the support base, providing more installation space for the duct and making installation more convenient. After the duct is installed in place, the clamping component is controlled to extend out of the top surface of the support base, so that the clamping component clamps both sides of the duct, which can restrict the horizontal movement of the duct and ensure error-free connection between adjacent ducts. Since the width between the two clamping components is consistent with the width of the duct, the clamping component can be controlled to extend after the position of the duct is adjusted to be exactly between the two clamping components.

[0010] Preferably, the width of the support base is smaller than the width of the air duct, and the clamping member is pulled at both ends of the support base by clamping springs;

[0011] The clamping component includes a clamping base connected to the clamping spring and a clamping plate movably disposed on the clamping base. The top surface of the clamping base is flush with the top surface of the support base. The clamping plate is used to be disposed in the clamping base before the air duct is installed and to extend out from the clamping base to clamp both sides of the air duct after the air duct is installed in place.

[0012] By adopting the above technical solution, after the air duct is installed in place, pulling the two clamping parts causes the clamping springs to stretch, and at the same time, the clamping plate is controlled to extend from the clamping base. After the clamping base is pulled out a certain distance, the force applied to the clamping base is released. Under the restoring force of the clamping springs, the clamping plate adheres tightly to both sides of the air duct, limiting the horizontal movement of the air duct. The clamping springs located on both sides of the air duct can also produce a good shock absorption effect on the air duct.

[0013] Preferably, the clamping plate is hinged to the top of the clamping base by a pin or slidably connected within the clamping base.

[0014] By adopting the above technical solution, the connection between the clamping plate and the clamping base can be either hinged or sliding. When the clamping plate is hinged to the clamping base, after the clamping component is pulled out, the clamping plate is pulled out from the clearance space and the clamping plate rotates around the hinge point with the clamping base, so that the clamping plate extends to the support seat. When the clamping plate is slidingly connected to the clamping base, the clamping plate is directly pushed upward to slide so that the clamping plate extends out of the support seat and is clamped on both sides of the air duct.

[0015] Preferably, the width of the support base is greater than the width of the duct, the clamping members are located on both sides of the duct, and the clamping members include a fixed base installed in the support base with a compression spring inside, a clamping block that presses the compression spring and is slidably connected in the fixed base, and a limiting pin that limits the position of the clamping block in the fixed base when the compression spring is pressed. Before the duct is installed in place, the top surface of the clamping block is flush with the top surface of the support base.

[0016] By adopting the above technical solution, before the duct is installed in place, the clamping block presses the compression spring, and the limiting pin is stuck on the side wall of the clamping block to limit the position of the clamping block in the fixed seat. At this time, the top surface of the fixed seat is flush with the support seat to facilitate the installation of the duct. After the duct is installed in place, the limiting pin is pulled out, and the clamping block pops out from the fixed seat under the restoring force of the compression spring, so that the clamping block is clamped on both sides of the duct to achieve horizontal limitation of the duct.

[0017] Preferably, the horizontal limiting component is slidably connected inside the first horizontal hanger. The first horizontal hanger has a groove for the support to slide. Guide blocks are fixed on both sides of the support. Guide grooves for the guide blocks to slide are formed on the two opposite inner walls of the first horizontal hanger. A drive component is installed on the first horizontal hanger to drive the horizontal limiting component to slide so as to finely adjust the installation position of the air duct.

[0018] By adopting the above technical solution, the length of the horizontal limiting component is less than the length of the first horizontal hanger. When there is a horizontal installation deviation between the air duct and the adjacent air duct, the horizontal position of the air duct is finely adjusted by adjusting the driving component, so that the air duct and the adjacent air duct are connected without error. While ensuring the horizontal limiting of the air duct, the adjustment efficiency of adjusting the horizontal position of the air duct is improved. The sliding of the guide block in the limiting groove ensures the horizontal movement of the support.

[0019] Preferably, the driving component includes a rotating shaft passing through the side wall of the first horizontal hanger and rotatably connected to the first horizontal hanger, a drive gear fixed inside the rotating shaft, and a rack installed at the bottom of the support for meshing with the drive gear. A knob is installed at one end of the rotating shaft outside the first horizontal hanger.

[0020] By adopting the above technical solution, when making fine adjustments to the position of the air duct, the construction personnel manually turn the knob on the outside to drive the drive gear to rotate. When the drive gear rotates, it drives the rack and the support seat to slide horizontally along the first horizontal hanger. Through the cooperation and transmission of the drive gear and the rack, the position of the support seat within the first horizontal hanger is finely adjusted.

[0021] Preferably, the second horizontal hanger is hinged to the vertical hanger via connectors at both ends. The second horizontal hanger is used to fold down below the first horizontal hanger during duct installation. The vertical hanger is provided with a limiting member for connecting to the second horizontal hanger after the duct is installed in place to restrict the position of the second horizontal hanger.

[0022] By adopting the above technical solution, since the duct is located between the first horizontal hanger and the second horizontal hanger, in order to avoid the second horizontal hanger affecting the installation of the duct, the second horizontal hanger is flipped under the first horizontal hanger during the installation of the duct. After the duct is installed in place, the second horizontal hanger is flipped over to the first horizontal hanger and fixed with the limiting component, so as to fix the position of the second horizontal hanger on the vertical hanger, which facilitates the installation of the duct.

[0023] Preferably, the connector includes a hinge plate hinged to the vertical rod and a shock-absorbing spring connected between the hinge plate and the second horizontal hanger. The second horizontal hanger is used to rotate around the hinge point and stretch the shock-absorbing spring until it is engaged in the limiting member after the duct is installed in place.

[0024] By adopting the above technical solution, and by setting a shock-absorbing spring between the second horizontal hanger and the vertical hanger, when the second horizontal hanger is pulled to engage with the limiting component, the shock-absorbing spring is in a stretched state, and the shock-absorbing spring can play a good role in damping water supply pipes, fire pipes, and air ducts.

[0025] Preferably, the limiting member includes a limiting seat fixed on the vertical rod. The limiting seat has an inlet groove for the second horizontal hanging seat to extend into on the side opposite to the vertical rod, and a limiting groove communicating with the inlet groove. The longitudinal section of the limiting groove is U-shaped, so that a stop block is formed on the outer side of the limiting groove to restrict the second horizontal hanging seat from disengaging from the limiting seat.

[0026] By adopting the above technical solution, when the second horizontal hanger is flipped and pulled to be flush with the inlet groove of the limiting member, the second horizontal hanger is pushed into the inlet groove and then released, so that the second horizontal hanger sinks and gets stuck in the limiting groove under the restoring force of the shock-absorbing spring. Due to the limiting effect of the baffle on the outer side of the limiting groove, the second horizontal hanger is prevented from detaching from the limiting member.

[0027] On the other hand, this application provides a limiting method for a horizontal limiting device for an electromechanical module, comprising the following steps:

[0028] S1: Fix the support frame body in sequence according to the positions measured on site;

[0029] S2: Install the duct: Disconnect the second horizontal hanger from the limiting piece, keep the top surface of the clamping piece flush with the top surface of the support, and install the duct on the support.

[0030] S3: Control the clamping member to extend above the support base and clamp the air duct;

[0031] S4: Installation of round pipes such as water supply pipes: Pull the second horizontal hanger to make it snap into the limiting piece, and install the round pipe into the clamp of the matching specification.

[0032] By adopting the above technical solution, after the air duct is installed in place, the control clamp extends to the upper surface of the protruding support base, and the clamp clamps are just clamped on both sides of the air duct, so as to realize the horizontal limit of the air duct position while facilitating the vertical lifting and installation of the air duct.

[0033] In summary, this application includes at least one of the following beneficial technical effects:

[0034] 1. This application provides a horizontal limiting component on the first horizontal hanger to clamp the clamping member on both sides of the duct, thereby effectively limiting the horizontal position of the duct. Before the duct is installed in place, the clamping member is kept flush with the top surface of the support. After the duct is installed in place, the clamping member extends to clamp both sides of the duct, thereby effectively limiting the horizontal position of the duct without obstructing the installation of the duct.

[0035] 2. By sliding the horizontal limiting component into the first horizontal hanger and setting a driving component to drive the horizontal limiting component to slide within the first horizontal hanger, the driving component can make minor adjustments to the position of the horizontal limiting component. When there is a slight error between the air duct and the adjacent air duct, the driving component can make fine adjustments.

[0036] 3. By making the second horizontal hanger rotatable on the vertical hanger, the second horizontal hanger is prevented from affecting the vertical lifting and installation of the duct. The position of the second horizontal hanger on the vertical hanger is limited by the cooperation of the second horizontal hanger and the limiting component. A shock-absorbing spring is connected between the hinge of the second horizontal hanger and the vertical hanger, which can provide a good vibration damping effect for the electromechanical module.

[0043] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0044] This application discloses a horizontal limiting device for an electromechanical module. (Refer to...) Figure 1 and Figure 2 The horizontal limiting device of the electromechanical module includes a support body 1 for fixing to the top plate of the structure by expansion bolts and a horizontal limiting component 2 installed on the support body 1 for horizontally limiting the position of the air duct 6.

[0045] Reference Figure 1 and Figure 2 The support body 1 includes two vertically arranged vertical hangers 11, a first horizontal hanger 12 horizontally connected between the two vertical hangers 11, and a second horizontal hanger 13 horizontally connected between the two vertical hangers 11. The first horizontal hanger 12 is located above the second horizontal hanger 13, and a space for installing the air supply duct 6 is formed between the first horizontal hanger 12 and the second horizontal hanger 13. Several pipe clamps 14 of different specifications are installed on the upper surface of the second horizontal hanger 13 for the installation and positioning of circular pipes such as fire pipes and water supply pipes.

[0046] Reference Figure 1 and Figure 2 The horizontal limiting assembly 2 includes a support base 21 mounted on the first horizontal hanger 12 and clamping members 22 mounted at both ends of the support base 21. The width between the two clamping members 22 is the same as the width of the duct 6. The clamping members 22 are used to keep the top surface of the support base 21 flush before the duct 6 is installed in place, and extend to clamp both sides of the duct 6 after the duct 6 is installed in place. Since the clamping members 22 have not yet extended when the duct 6 is installed, the horizontal limiting of the duct 6 can be achieved without affecting the vertical lifting and placement of the duct 6 on the first horizontal hanger 12.

[0047] Reference Figure 1 and Figure 3 In one specific structural embodiment, the width of the support base 21 is smaller than the width of the duct 6, and the clamping member 22 is pulled at both ends of the support base 21 by the clamping spring 221. The clamping member 22 includes a clamping base 222 connected to the clamping spring 221 and a clamping plate 223 movably disposed on the clamping base 222. The top surface of the clamping base 222 is flush with the top surface of the support base 21. The clamping plate 223 is used to be hidden in the clamping base before the duct 6 is installed in place and to extend from the clamping base 222 to clamp both sides of the duct 6 after the duct 6 is installed in place. Mounting grooves 211 extending in the same direction as the length of the support base 21 are provided at both ends of the support base 21. The end of the clamping spring 221 away from the clamping member 22 is fixedly installed at the bottom of the mounting groove 211, so that the clamping member 22 abuts against both ends of the support base 21 in the initial state. After the duct 6 is placed on the support base 21, the construction worker pulls the clamping members 22 simultaneously at both ends, causing the clamping members 22 to stretch the clamping springs 221. Simultaneously, the clamping plate 223 is pulled, extending from the clamping base 222 so that it protrudes from the top surface of the support base 21. Then, the force applied to the clamping base 222 is released, and the clamping plate 223, under the restoring force of the clamping springs 221, adheres tightly to both sides of the duct 6, limiting the horizontal movement of the duct 6. The clamping springs 221 located on both sides of the duct 6 also provide good shock absorption. To improve the clamping stability of the clamping members 22, high-strength springs can be used for the clamping springs 221, or the strength can be increased by increasing the number of clamping springs 221.

[0048] There are multiple ways in which the clamping plate 223 extends out of the clamping base 222. This application only proposes two convenient ways to implement:

[0049] Reference Figure 1 In one easily implemented method, the clamping plate 223 is hinged to the top of the clamping base 222 by a pin. The clamping base 222 has a first clearance space 2221 for the clamping plate 223 to fold and rotate. Pulling the clamping plate 223 causes it to rotate and fold around the hinge axis between the clamping plate 223 and the clamping base 222, allowing the clamping plate 223 to extend from the clamping base 222 to protrude from the top surface of the support 21. Using a nut to tighten the end of the pin secures the position of the clamping plate 223, reducing the probability of it folding back down under gravity. The first clearance space 2221 is a U-shaped groove within the clamping base 222. When the duct 6 is installed, the clamping plate 223 is perpendicular to the clamping base 222 and faces away from the duct 6.

[0050] In another easily implemented method (not shown in the figure), the clamping plate 223 is slidably connected within the clamping base 222. A second clearance space is provided on the side wall of the clamping base 222 for the clamping plate 223 to be embedded in. The clamping plate 223 can slide out along the clearance space. To limit the position of the clamping plate 223 after it extends, it can be restricted by bolts or pins. The second clearance space can be located on any one of the four sides of the clamping base 222, but for ease of installation of the clamping spring 221, the second clearance space is located on the other three sides besides the side where the clamping spring 221 is installed.

[0051] Reference Figure 2 and Figure 4 In another specific structural embodiment, the width of the support base 21 is greater than the width of the duct 6. The clamping members 22 are located on both sides of the duct 6. The clamping members 22 include a fixed base 225 installed in the support base 21 with a compression spring 224 inside, a clamping block 226 that presses the compression spring 224 and is slidably connected in the fixed base 225, and a limiting pin 227 that limits the position of the clamping block 226 in the fixed base 225 when the compression spring 224 is pressed. Before the duct 6 is installed in place, the clamping block 226 presses the compression spring 224, and the limiting pin 227 is vertically inserted into the side wall of the fixed seat 225 and the clamping block 226 to limit the position of the clamping block 226 in the fixed seat 225. At this time, the top surface of the fixed seat 225 is flush with the support seat 21 to facilitate the installation of the duct 6. After the duct 6 is installed in place, the limiting pin 227 is pulled out, and the clamping block 226 pops out from the fixed seat 225 under the restoring force of the compression spring 224, so that the clamping block 226 is clamped on both sides of the duct 6 to achieve horizontal limitation of the duct 6.

[0052] Reference Figure 5 To facilitate fine-tuning of the installation position of the duct 6 and ensure error-free installation between adjacent ducts 6, the length of the horizontal limiting component 2 is less than the length of the first horizontal hanger 12, and the horizontal limiting component 2 is slidably connected within the first horizontal hanger 12. A sliding groove 121 for the support base 21 to slide is provided within the first horizontal hanger 12. A driving component 3 is installed on the first horizontal hanger 12 to drive the horizontal limiting component 2 to slide and fine-tune the installation position of the duct 6. (Refer to...) Figure 5 The driving component 3 includes a rotating shaft 31 that passes through and is rotatably connected to the first horizontal support 12, a drive gear 32 fixed inside the rotating shaft 31, and a rack 33 mounted on the bottom of the support 21 for meshing with the drive gear 32. A knob 34 for easy turning is installed at the end of the rotating shaft 31 located outside the first horizontal support 12. The rotating shaft 31 is rotatably connected to the side wall of the first horizontal support 12 via bearings. Through the engagement of the drive gear 32 and the rack 33, minute adjustments to the position of the support 21 within the first horizontal support 12 are achieved.

[0053] Reference Figure 5 In order to guide and limit the sliding of the support 21 in the slide groove 121, guide blocks 212 are fixed on both sides of the support 21, and guide grooves 122 for sliding of the guide blocks 212 are provided on the two opposite inner walls of the first horizontal hanger 12.

[0054] Reference Figure 3 To minimize the impact of the second horizontal hanger 13 on the vertical lifting and installation of the duct 6, the second horizontal hanger 13 is hinged to the vertical hanger 11 via connectors 4 at both ends. The second horizontal hanger 13 is used to fold below the first horizontal hanger 12 during the installation of the duct 6. The vertical hanger 11 is equipped with a limiting member 5 for connecting to the second horizontal hanger 13 after the duct 6 is installed, thus restricting the position of the second horizontal hanger 13. When the duct 6 is installed, it causes the second horizontal hanger 13 to rotate around the hinge axis between the connector 4 and the vertical hanger 11, connecting the second horizontal hanger 13 to the limiting member 5 and fixing its position on the vertical hanger 11.

[0055] Reference Figure 3 Specifically, the connector 4 includes a hinge plate 41 hinged to the vertical hanger 11 and a shock-absorbing spring 42 connected between the hinge plate 41 and the second horizontal hanger 13. The second horizontal hanger 13 is used to rotate around the hinge point and stretch the shock-absorbing spring 42 until it is engaged with the limiting member 5 after the duct 6 is installed in place. The hinge point between the hinge plate 41 and the vertical hanger 11 is located at the connection between the first horizontal hanger 12 and the vertical hanger 11.

[0056] When the second horizontal hanger 13 is pulled to engage with the limiting component 5, the shock-absorbing spring 42 is in a stretched state, and the shock-absorbing spring 42 can play a good role in damping the water supply pipe, fire pipe, and air duct 6.

[0057] Reference Figure 3 The limiting member 5 includes a limiting seat 51 fixed to one side of the vertical rod 11. The limiting seat 51 has an inlet groove 511 on the side opposite to the vertical rod 11 for the second horizontal support 13 to extend into, and a limiting groove 512 communicating with the inlet groove 511. The longitudinal section of the limiting groove 512 is U-shaped, forming a stop 513 on the outer side of the limiting groove 512 to prevent the second horizontal support 13 from detaching from the limiting seat 51. When the second horizontal support 13 is flipped and pulled until it is flush with the inlet groove 511 of the limiting member 5, the second horizontal support 13 is pushed into the inlet groove 511. Then, the second horizontal support 13 is released, causing it to sink and lock into the limiting groove 512 under the restoring force of the shock-absorbing spring 42. Due to the limiting effect of the outer baffle of the limiting groove 512, the second horizontal support 13 is prevented from detaching from the limiting member 5.

[0058] The implementation principle of the horizontal limiting device for an electromechanical module in this embodiment is as follows: When the support bracket body 1 is fixed, the connecting piece 4 is located on the side opposite to the installation direction of the air duct 6. When the air duct 6 is installed, the second horizontal hanger 13 is first disengaged from the limiting groove 512 of the limiting seat 51, so that the second horizontal hanger 13 flips to below the first horizontal hanger 12. Then, the air duct 6 is installed on the support base 21. After the air duct 6 is installed in place, the clamping piece 22 is extended to clamp both sides of the air duct 6. When the position of the subsequently installed air duct 6 is offset from that of the previous air duct 6, the knob 34 is manually turned, and the horizontal limiting component 2 and the air duct 6 are moved through the transmission of the drive gear 32 and the rack 33 to make a small adjustment to the installation position of the air duct 6. After the air duct 6 is installed, the second horizontal hanger 13 is rotated and the shock-absorbing spring 42 is stretched, so that the second horizontal hanger 13 extends from the inlet groove 511 and is re-clamped into the limiting groove 512 of the limiting seat 51. Then, circular pipes such as water supply pipes and fire-fighting pipes are installed inside the pipe clamp 14 of the second horizontal hanger 13.

[0059] This application also discloses a limiting method for a horizontal limiting device for an electromechanical module. (Refer to...) Figure 1 It includes the following steps:

[0060] S1: Fix the support frame body 1 in sequence according to the positions measured on site;

[0061] S2: Install duct 6: Disconnect the second horizontal hanger 13 from the limiting member 5, keep the top surface of the clamp 22 flush with the top surface of the support 21, and install the duct 6 on the support 21.

[0062] S3: Control the clamping member 22 to extend above the support base 21 and clamp the air duct 6;

[0063] S4: Install round pipes such as water supply pipes: Pull the second horizontal hanger 13 to make it snap into the limiting piece 5, and install the round pipe into the clamp with matching specifications.

[0064] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
