Abstract
A bracket toe for mounting a firefighting smoke-exhausting axial flow fan comprises an angle bottom plate, wherein two ends of the angle bottom plate are fixedly connected with the lower end of a left-side angle edge plate and the lower end of a right-side angle edge plate respectively; the angle bottom plate, the left-side angle edge plate and the right-side angle edge plate form a top opening type trapezoidal structure; the left-side angle edge plate and the right-side angle edge plate are arranged symmetrically; the upper end edge shape of the left-side angle edge plate and the upper end edge shape of the right-side angle edge plate adapt to an outer cylinder wall of the external fan; a bolt hole I and a bolt hole II which are formed symmetrically and used for connecting and mounting a base are formed in the angle bottom plate; a threaded rod hole I used for being fixedly connected with an external hoisting threaded rod is formed in a position, corresponding to a central line of the bolt hole I, of the left-side angle edge plate; and a threaded rod hole II used for being fixedly connected with the external hoisting threaded rod is formed in a position, corresponding to a central line of the bolt hole II, of the right-side angle edge plate. The bracket toe is high in installation efficiency and wide in application range, can be processed simply and rapidly, and is also suitable for cylinder type fans such as oblique flow fans, mixed flow fans and the like.
Description
Technical field
The utility model relates to a kind of stent foot that blower fan is installed, and especially relates to a kind of for the stent foot of fire smoke discharging axial flow fan is installed.
Background technique
In the basic installation place of fire-fighting high-temperature smoke discharging cylinder type blower fan, need to be with by fire-protection high temp and stent foot that fixedly blower fan links together.
Existing fan supporter pin, profile is rectangular, and when blower fan lifts in the air, the installer needs scene to make one to add large-scale connection bracket, to the installer, bring a lot of troubles again, and installation efficiency is low; Due to technological reason, stent foot length must be less 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, then with Presseshydraulic carry out the angle of attack, punching lacks, then by operations such as artificial bendings, manufacturing forms, and quality of product is difficult for stable.
The model utility content
Technical problem to be solved in the utility model is, overcomes the above-mentioned defect that prior art exists, and provides a kind of
Easy to install and use, manufacturing process is simple, and steady quality is reliably for installing the stent foot of fire smoke discharging axial flow fan.
The utility model solves the technological scheme that its technical problem adopts, it is a kind of for the stent foot of fire smoke discharging axial flow fan 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 form open top formula trapezium structure; Described left hand corner side plate and right-hand corner side plate are symmetrical arranged, and size and shape is identical; 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 the two symmetrically arranged I of the bolt hole for the connection basis and bolt hole II, on the left hand corner side plate, with bolt hole I center line corresponding part, is provided with for the screw hole I affixed with external lifting screw rod; On the right-hand corner side plate, with bolt hole II center line corresponding part, be provided with for the screw hole II affixed with external lifting screw rod.
Further, the angle formed between described left hand corner side plate and right-hand corner side plate and angle base plate is 70～75 degree (more preferably 72 degree) preferably.
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.
The utility model stent foot, can select the angle steel section bar that meets the national Specification requirement, by the hydraulic combined punching & shearing machine blanking, utilizes the mould punching moulding.
The utility model processing simple and fast, low cost of manufacture, constant product quality, the size exchangeability performance is good, and profile is smooth attractive in appearance; The use installation efficiency is high, than prior art, can improve more than 5 times, and installation work-hour shortens, and labor strength alleviates; Applied widely, except the installation that is applicable to fire smoke discharging axial flow fan, the also installation of the cylinder type blower fans such as applicable diagonal flow fan, flow-mixing blower fan.
