Abstract
A support foot used for installation of a fire-fighting smoke-discharging axial flow fan comprises an angle bottom plate. The two ends of the angle bottom plate are fixedly connected with the lower end of a left angle side plate and the lower end of a right angle side plate respectively. The angle bottom plate, the left angle side plate and the right angle side plate constitute a trapezoidal frame with an open top. The left angle side plate and the right angle side plate are symmetrically arranged. The shape of the upper end edge of the left angle side plate and the shape of the upper end edge of the right angle side plate are matched with the shape of the outer cylinder wall of an external fan. The angle bottom plate is provided with a bolt hole I and a bolt hole II which are symmetrically arranged and used for being connected with an installation foundation. A position, corresponding to the center line of the bolt hole I, on the left angle side plate, is provided with a screw rod hole I used for being fixedly connected with an external hoisting screw rod. A position, corresponding to the center line of the bolt hole II, on the right angle side plate, is provided with a screw rod hole II used for being fixedly connected with the external hoisting screw rod. The support foot is high in installation efficiency, easy and quick to machine, and wide in application range, and is also suitable for cylindrical fans such as an oblique flow fan and a mixed flow fan.
Description
Technical field
The present invention relates to a kind of stent foot that blower fan is installed, especially relate to a kind of for the stent foot that fire-fighting smoke evacuation axial-flow blower is installed.
Background technique
In the basic installation place of fire-fighting high temperature smoke evacuation cylinder type blower fan, need be with fire-fighting High-temp. smoke-exhausting fan and the fixing stent foot that links together of blower fan.
Existing fan supporter pin, profile are rectangular, and when blower fan lifted in the air, the installer needed the scene to make one again to add large-scale connection support, bring a lot of troubles to the installer, and installation efficiency is low; Because technological reason, stent foot length must be littler than blower fan urceolus maximum diameter, has a strong impact on project progress.And manufacturing process's complexity must adopt the high-quality angle steel section bar that meets the national Specification requirement, use the angle shears blanking by artificial, carry out the angle of attack, dash and lack with Presseshydraulic again, then by operations such as artificial bendings, manufacturing forms, and quality of product is difficult for stable.
Summary of the invention
Technical problem to be solved by this invention is, overcomes the above-mentioned defective that prior art exists, and provides a kind of
Easy to install and use, manufacturing process is simple, and steady quality is used for installing the stent foot of fire-fighting smoke evacuation axial-flow blower reliably.
The technical solution adopted for the present invention to solve the technical problems is, a kind of for the stent foot that fire-fighting smoke evacuation axial-flow blower is installed, comprise the angle base plate, the two ends of described angle base plate are connected with the lower end of left hand corner side plate and the lower end of right-hand corner side plate respectively, and described angle base plate, left hand corner side plate and right-hand corner side plate constitute open top formula trapezium structure; Described left hand corner side plate and right-hand corner side plate are symmetrical arranged, and size is identical with shape; Limit, the upper end shape of limit, the upper end shape of described left hand corner side plate and right-hand corner side plate all adapts with external blower fan outer tube wall; Described angle base plate is provided with two symmetrically arranged bolt hole I and bolt hole II for the connection basis, on the left hand corner side plate, is provided with for the screw hole I affixed with external lifting screw rod with bolt hole I center line corresponding part; On the right-hand corner side plate, be provided with for the screw hole II affixed with external lifting screw rod with bolt hole II center line corresponding part.
Further, preferred 70～75 degree of the angle that constitutes between described left hand corner side plate and right-hand corner side plate and the angle base plate (more preferably 72 degree).
Further, the preferred long waist shaped screw hole of described screw hole shape.
Further, the length of described angle base plate, preferred external blower fan urceolus diameter and bolt hole I and bolt hole II two diameter of bolt hole sums.
Stent foot of the present invention can be selected the angle steel section bar that meets the national Specification requirement for use, by the hydraulic combined punching ﹠ shearing machine blanking, utilizes the mould impact briquetting.
The present invention processes simple and fast, low cost of manufacture, and constant product quality, the size exchangeability performance is good, and profile is smooth attractive in appearance; Use installation efficiency height can improve more than 5 times than prior art, and installation work-hour shortens, and labor strength alleviates; Applicable scope is extensive, except the installation that is applicable to fire-fighting smoke evacuation axial-flow blower, also is suitable for the installation of cylinder type blower fans such as diagonal flow fan, flow-mixing blower fan.
