Description

Technical Field

[0001] The utility model relates to the field of composite air duct installation, in particular to a composite air duct installation support device for subways. Background Art

[0002] Air ducts are pipes used in air supply systems. There are two types: composite air ducts and inorganic air ducts. According to the material, air ducts can be divided into metal air ducts, composite air ducts, polymer air ducts, etc. Air ducts are widely used in construction projects. Air ducts are usually used to keep indoor air fresh, reduce energy consumption, and effectively prevent the spread of bacteria and viruses.

[0003] The connection and fixing structure is an indispensable structure in the process of duct splicing and installation. During the installation of the composite duct, the composite duct is pushed to the installation height through the top plate, and the composite duct is installed. During the pushing process, the composite duct is prone to offset, so the staff needs to adjust the composite duct, which reduces the work efficiency of the composite duct installation process in the subway.

[0004] A composite air duct hoisting construction device (patent announcement number: CN216201106U) drives the push rod to move through the driving jacking device set on the hoisting platform, pushes the air duct onto the installation plate, and moves between the two slide rails, which can complete the one-time positioning of the entire air duct. The installation tools and parts can be placed through the hoisting platform and the assembly platform to avoid the inconvenience of taking and placing the installation tools and parts during the air duct installation process, which affects the work efficiency of the air duct installation. However, this method relies on the hoisting platform and is suitable for the hoisting of composite air ducts in high factories. For the installation of composite air ducts in subway tunnels, this type of device is obviously not suitable. Utility Model Content

[0005] The utility model aims to overcome the shortcomings of the prior art and provide a supporting device suitable for installing a composite air duct in places such as subway tunnels which are not particularly high.

[0006] The purpose of this utility model is achieved through the following technical solutions:

[0007] A composite air duct installation support device for subways, comprising a support mechanism and an adjustment mechanism, wherein the adjustment mechanism is arranged on the support mechanism;

[0008] The supporting mechanism includes a telescopic sleeve and a driving assembly, wherein the driving assembly is connected to the telescopic sleeve and is used to drive the telescopic sleeve to extend and retract;

[0009] The adjustment mechanism includes a first fixing seat arranged at the top of the telescopic sleeve, a first connecting rod hinged to the first fixing seat, a second fixing seat arranged at the end of the first connecting rod, and a support plate connected to the second fixing seat;

[0010] The first fixing seat comprises an upper supporting plate and a lower supporting plate, an end portion of the first connecting rod is inserted between the upper supporting plate and the lower supporting plate, and the first fixing seat and the first connecting rod are connected via a hinge shaft;

[0011] Two groups of support mechanisms are provided, and two first fixing seats are provided on the telescopic sleeve of each group of support mechanisms, and each first fixing seat is correspondingly provided with a first connecting rod; the two first fixing seats are arranged side by side on the telescopic sleeve of each group of support mechanisms.

[0012] As a preferred embodiment, the second fixing seat is fixed to the support plate, and the second fixing seat is hinged to the first connecting rod.

[0013] As a preferred embodiment, the support plate is an L-shaped support plate. The L-shaped support plate is provided to support the air duct and has a support on the side.

[0014] As a preferred embodiment, an anti-skid pad is provided on the support plate to prevent the air duct from slipping.

[0015] As a preferred embodiment, a return spring is arranged between the first connecting rods correspondingly arranged on the first fixing seat, and both ends of the return spring are respectively arranged on the two first connecting rods.

[0016] As a preferred embodiment, the telescopic sleeve includes an upper sleeve and a lower sleeve, and the upper sleeve extends into the lower sleeve, which can play a lifting and lowering guiding role to a certain extent.

[0017] As a preferred embodiment, the driving component is an electric telescopic rod, and the telescopic end of the electric telescopic rod is connected to the upper sleeve to facilitate driving the telescopic sleeve to rise and fall.

[0018] As a preferred embodiment, the support mechanism further comprises a base, and the telescopic sleeve and the driving assembly are both arranged on the base. As a preferred embodiment, a groove is arranged on the base, and a bidirectional screw rod is arranged in the groove, and movable seats are respectively arranged at both ends of the bidirectional screw rod, and the movable seats are threadedly connected to the bidirectional screw rod; the telescopic sleeve and the driving assembly are both arranged on the movable seat.

[0019] As a preferred embodiment, one end of the bidirectional lead screw passes through the groove wall and is connected to the output end of the motor.

[0020] The utility model has at least the following beneficial effects: the telescopic sleeve of the support mechanism realizes the telescopic function through the driving assembly, so that the telescopic sleeve drives the first fixing seat to be lifted and lowered, thereby driving the support plate to be lifted and lowered. After the composite air duct is placed on the support plate, it can be lifted and lowered by the driving assembly. Due to the use of the matching structure of the telescopic sleeve and the driving assembly, the composite air duct cannot be lifted to a high height like a lifting platform, and is generally suitable for the installation of composite air ducts in places such as subway tunnels with a height of no more than 5 meters.

[0021] The first connecting rod is hinged to the first fixing seat. When in use, the first connecting rod can be rotated to facilitate moving the composite air duct to the support plate. The first fixing seat adopts the form of upper and lower support plates, which has high strength and avoids the problem of deformation of the single-plate fixing seat. Two groups of support mechanisms are set up, and the air duct is supported by two groups of support mechanisms. During the process of lifting or installing the air duct, the air duct is more stable and not easy to shake. The structure of two first fixing seats on one side, combined with two groups of support mechanisms, can support the air duct from four directions of front, back, left and right, and the supporting effect is better.
