The utility model is used for cleaning the dirt of the screw rod in a quick dismounting system in building operation, replacing the conventional manual cleaning, enhancing efficacy, reducing labor strength; the utility model has no damage for thread, and has repair function. The utility model has the advantages of simple structure, low cost, simple, convenient and flexible operation, time saving, labor saving, etc., and can be widely used for cleaning screw rods with various specifications.

Description

The leading screw descaling machine

The utility model relates to a kind of leading screw descaling machine that is used for clearing up building operations quick detach system leading screw dirt.

In building operations, bowl fastening type scaffold, template quick detach system with its easy accessibility, quick, combination flexibly, advantage such as labour intensity is low and being widely adopted, thereby be accelerating construction progress, improve workmanship, the increase project benefit has been brought into play important function.But in this system, play the shoring of key effect, cleaning problem that collet is torn first-class leading screw early open, but allow the user hinder brains, because after each the use, because the ash etc. of spilling, land during concreting causes collet, shores and early dismantling head sticks mortar and concrete, does not clear up and just can't continue use.The leading screw cleaning does not still have effective way at present, is the labor cleaning.Generally want in used oil, to soak earlier several hrs, and then pick brush with instruments such as wire brush, iron hammer, little drill rods, cleaning work is difficulty very, waste time and energy, each operates two people can only clear up 20 at most every day, work efficiency is extremely low, and the scrappage of leading screw has seriously influenced applying of bowl fastening type scaffold and template quick detach system up to 10%.

The purpose of this utility model is to address the above problem and provides a kind of easy and simple to handle, safe and reliable, time saving and energy saving, utilizes the power that produces in tangential direction between the cutter and screw thread in the leading screw rotary course, the leading screw descaling machine that dirts such as mortar are cleaned out.

The purpose of this utility model is achieved by the following technical solution:

A kind of leading screw descaling machine comprises motor, transmission mechanism, frame, cutter, it is characterized in that frame is provided with gearbox, bearing support, retaining thick stick; One output shaft coupling turn-screw of gearbox, screw, another output shaft coupling flange; Knife rest is arranged on the screw.

Described bearing support can move adjusting.

The utility model has substituted traditional manual cleanup, a machine per hour can be cleared up surplus the leading screw 20 piece, improved efficiency greatly, alleviated labour intensity, and screw thread do not had any damage, and can do certain reparation to the screw thread that damages in the construction simultaneously, improved the utilization rate of leading screw, reduce the quantity of scrapping of leading screw, reduced construction cost.Because the removable adjusting of bearing support, the utmost point are applicable to the leading screw cleaning of plurality of specifications, have wide range of applications.Characteristics such as the utility model also has simple in structure being easy to be made, with low cost, easy and simple to handle, flexible, safe, time saving and energy saving, economical and practical.

Description of drawings:

Fig. 1 is the utility model structural representation;

Fig. 2 is a cutter structure schematic diagram of the present utility model;

Fig. 3 is a transmission mechanism sketch of the present utility model.

Below in conjunction with drawings and Examples the utility model is elaborated: consult Fig. 1, shown in Figure 2, the leading screw descaling machine mainly is by frame 1, motor 2, gearbox 3, flange 4, turn-screw 5, retaining thick stick 8, bearing support 9, switch 10, screw 14 and includes the cutter of knife rest 6, knife bar 11, trip bolt 12, cutter head 13, handwheel 15 and transmission mechanism etc. constitutes.Its frame 1 can adopt angle steel, channel-section steel etc. to be welded, and gearbox 3 is installed on the frame 1, and its housing can adopt the 2mm steel plate to make, and plays the security protection effect.Bearing support 9, retaining thick stick 8, the stacked switch 10 etc. of removable adjusting also are installed on the frame 1; Turn-screw 5, screw 14 on the one output shaft coupling bearing support 9 of gearbox 3, another output shaft coupling flange 4; Knife rest 6 is welded on the screw 14 and is erected on the retaining thick stick 8, and knife bar 11 is housed in the knife rest 6, one client link rotation hand wheel 15, and the other end is fixed with cutter head 13 by trip bolt 12.

Consult shown in Figure 3ly, transmission mechanism of the present utility model is arranged in gearbox 3 housings, adopts meshed transmission gear, and first class reducer structure, motor are covered with 2mm steel plate protective cover by the belt transmission belt pulley.Motor 2 output shaft coupling small belt pulleys 16, connect big belt 18 by belt 17, its wheel shaft connects driver pinion 20, pinion 20 driven gear wheels 19 of engagement and 21, two driven gear shafts connect turn-screw 5 and workpiece leading screw 7 respectively, and knife rest 6 connects firmly on the screw 14 of turn-screw 5.Respectively be provided with bearing and bearing holder (housing, cover) on the above-mentioned wheel shaft, transmission mechanism can be with about motor 2 speed drops to 200 rev/min, to reach the purpose of not only removing mortar but also not destroying screw thread.

Operating principle of the present utility model is to utilize the power that produces in tangential direction between the cutter and screw thread in the leading screw rotary course, and dirts such as mortar are cleaned out.During operation, workpiece leading screw 7 is installed on flange 4 and the bearing support 9, Push switch 10, motor 2 starts, by the gearing of belt pulley, gear, drive leading screw 5 and workpiece 7 rotations, the cutter oblique cutting is gone in the knife rest 6 of frame 1 central authorities, cutter head 13 and screw thread interlock, and apply certain pressure by handwheel 15, make to produce friction between cutter head 13 and the screw thread, with the purpose that reaches cleaning and repair.
