Description

Technical Field

[0001] The utility model relates to a height-adjustable combustion engine air intake filter support device, belonging to the technical field of support devices. Background Art

[0002] The performance and operating reliability of the gas turbine are closely related to the quality and cleanliness of the air entering the unit. Therefore, in order to ensure the efficient and reliable operation of the unit, a good air intake system must be configured to filter the air entering the unit and remove impurities. Therefore, the air intake filter is an important part of the air intake system, among which the air intake filter can prevent birds, branches, paper, plastic bags, etc. from entering the unit. Generally speaking, the air intake of the air intake system is provided with a frame structure, holes are drilled on the frame, and the circular plate filter is fixed to the frame by bolts, so that the filter can be flexibly replaced.

[0003] The existing gas turbine air intake filter has the following problems during installation and use: the air intake filter is heavy, which makes it inconvenient to install it on the frame by bolts; secondly, the height of the air intake filter support device is fixed and cannot be adjusted according to the actual situation on site, which reduces the use range of the air intake filter. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a height-adjustable combustion engine air intake filter support device, which has a simple structure and is easy to install, and realizes the height adjustment of the air intake filter.

[0005] The utility model discloses a height-adjustable gas turbine air intake filter support device, comprising an air intake filter, a leg mounting frame and a plurality of adjustable leg assemblies, wherein the leg mounting frame is fixedly connected to the air intake filter, and the adjustable leg assemblies are evenly distributed at the bottom of the leg mounting frame;

[0006] The adjustable leg assembly includes a leg inner cylinder, a leg outer cylinder, a positioning bolt, a universal wheel and a connecting rod. The top of the leg outer cylinder is fixedly connected to the bottom of the leg mounting frame. The leg inner cylinder is inserted into the leg outer cylinder from the bottom of the leg outer cylinder. Positioning holes are symmetrically arranged on the wall of the leg inner cylinder. Three adjustment holes are symmetrically arranged on the wall of the leg outer cylinder along the vertical direction. The positioning bolts penetrate the positioning holes on the wall of the leg inner cylinder and the adjustment holes on the wall of the leg outer cylinder to connect the leg inner cylinder with the leg outer cylinder. The universal wheel is connected to the leg inner cylinder through the connecting rod, and the leg inner cylinder can move up and down on the connecting rod.

[0007] By setting up a leg mounting bracket, the leg mounting bracket is used to support the air intake filter and connect the adjustable leg assembly at the same time. By setting positioning holes on the leg inner tube and adjusting holes on the leg outer tube, one group of adjustment holes is aligned with the positioning holes. The positioning bolts pass through the positioning holes and the adjustment holes to connect the leg inner tube and the leg outer tube, so as to achieve the height adjustment of the leg mounting bracket, that is, the height adjustment of the air intake filter is achieved. The leg inner tube can move up and down on the connecting rod, which further increases the range of the air intake filter height adjustment.

[0008] The connecting rod is inserted into the inner tube of the leg, the upper part of the connecting rod is connected to the inner tube of the leg by threads, and the bottom of the connecting rod is connected to the universal wheel by threads. The height of the air intake filter can be accurately adjusted by rotating the connecting rod, which further increases the range of the height adjustment of the air intake filter.

[0009] The positioning bolt is a stud bolt. After the positioning bolt passes through the positioning hole and the adjustment hole, both sides are tightened by nuts, which improves the reliability of the connection and can quickly and conveniently adjust the height of the air intake filter.

[0010] The apertures of the positioning holes and the adjustment holes are adapted to the outer diameter of the positioning bolts. By arranging the adjustment holes on the outer tube of the leg and the positioning holes on the inner tube of the leg to be adapted to the outer diameter of the positioning bolts, relative sliding between the outer tube of the leg and the inner tube of the leg is prevented, which may cause damage to the parts.

[0011] There are two outrigger mounting frames, which are symmetrically distributed on both sides of the air inlet filter, so as to improve the stability of the air inlet filter.

[0012] The number of the adjustable leg assemblies is four, and the adjustable leg assemblies are evenly distributed at the bottom of the two leg mounting frames, thereby improving the stability of the air intake filter support.

[0013] The universal wheel is provided with a brake, so as to avoid shaking of the air intake filter when installing and ensure the stability of the air intake filter when installing and removing.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] (1) The utility model provides a support leg mounting frame, which is used to support the air intake filter and connect the adjustable support leg assembly. Positioning holes are provided on the support leg inner tube, and adjustment holes are provided on the support leg outer tube. One group of adjustment holes is aligned with the positioning holes. Positioning bolts penetrate the positioning holes and the adjustment holes to connect the support leg inner tube and the support leg outer tube, thereby achieving height adjustment of the support leg mounting frame, that is, achieving height adjustment of the air intake filter. The support leg inner tube can move up and down on the connecting rod, thereby further increasing the range of height adjustment of the air intake filter.

[0016] (2) The connecting rod is inserted into the inner tube of the leg, the upper part of the connecting rod is connected to the inner tube of the leg by a thread, and the bottom of the connecting rod is connected to the universal wheel by a thread. The height of the air intake filter can be accurately adjusted by rotating the connecting rod, which further increases the range of the height adjustment of the air intake filter.

[0017] (3) The diameter of the positioning hole and the diameter of the adjustment hole are matched with the outer diameter of the positioning bolt. By setting the adjustment hole on the outer tube of the outrigger and the positioning hole on the inner tube of the outrigger to match the outer diameter of the positioning bolt, relative sliding between the outer tube of the outrigger and the inner tube of the outrigger can be prevented, which may cause damage to the parts.
