Description
Technical field
The utility model is related to a kind of shells of driving drum.
Background technology
Municipal pipeline environment very severe is easy to happen corrosion and fatigue and destroys or make latent inside pipeline after long-time service
Cause leakage accident etc., especially water class pipeline at breakage in development of defects, is also easy to the accidents such as blocking.Therefore the pipe of pipeline
Interior detection, dredging are a highly important practical engineerings, and detection in pipe at present is removed contamination mostly also using manually being operated,
It is limited by factors such as line size, bad environments, causes great work intensity, working efficiency low, be based on the problem, occur at present
Pipe robot, such as：Roller type, spiral rotary drum type etc..For spiral rotary drum type pipe robot, helix drum is as machine
The driving part of people advances when helix drum rotates with frictions, driving pipe robots such as inner wall of the pipe or mud, existing spiral shell
The shell and roll body of rotating drum are structure as a whole, and shell abrasion belongs to attrition component greatly, leads to replacement cost height.
Utility model content
The purpose of this utility model is to provide a kind of shell of driving drum, the outer of helix drum in the prior art is solved
Shell and roll body are structure as a whole, the high technical problem of replacement cost.
In order to solve the above-mentioned technical problem the utility model, adopts the following technical scheme that：
A kind of shell of driving drum, shell are tubular, and the peripheral surface of shell is fixedly installed spiral along its length
Blade.Shell fixation is set in outside driving drum, and when pipe robot works, shell is rotated together with driving drum, works as machine
When mud etc. contacts in the roller of device people and the inner wall of pipeline or pipe, helical blade and inner wall of the pipe or mud friction, driving tube
Pipeline robot advances, and contact area is big, will not skid；When the roller of robot suspends in water, helical blade is equivalent to spiral shell
Paddle is revolved, draining driving pipe robot advances backward for helical blade rotation.Helical blade wear extent is big, quick abrasion, works as helical-blade
After piece excessive abrasion, driving capability is had a greatly reduced quality, so should regularly replace.By by shell it is seperated with driving drum design, only

It is further improved, the blade of the peripheral surface of the shell is continuous helical shape.
It is further improved, the helical blade is made of multiple spiral blade units, and multiple spiral blade units are in
Helical form is fixed at shell peripheral surface, and there are spacing, spiral blade unit and spiral shells between adjacent spirals blade unit
The screw pitch of vane piece is identical.
It is further improved, the top surface of the helical blade is provided with anti-skid chequer, prevents skid, increases frictional force.
It is further improved, the shell is an integral molding structure, inner cavity straight tube structure, if driving drum is column
Body, then it is very convenient when assembling, it is only necessary to which that casing is in driving drum.
It is further improved, the inner cavity that the shell is, and outer not shape is cone fusiformis.Bore fusiformis design, pipe machine
In work process, the middle part of shell contacts device people with tube wall, and both ends tilt, and prevent blocking, is conducive to pipe robot and advances.
It is further improved, the shell is double-body bike, and shell is by the plane dimidiation vertical with its axis or shell
Dimidiation in an axial direction.Double-body bike is easily installed the driving drum of non-columnar, dismantles.
It is further improved, the threaded hole for fixing shell and driving drum is offered on the shell, it is solid by screw
Fixed shell and driving drum, it is easy to disassemble.
Be further improved, the inner walls be provided with it is multiple with the matched locating piece of driving drum, in driving drum
Corresponding position offers locating groove, and locating piece is inserted into locating groove by when assembly, when preventing pipe robot from working, shell
It relatively rotates with driving drum.
It is further improved, the shell is provided at both ends with head plate, prevents water or dirt etc. from entering shell and is rolled with driving
In gap between cylinder.
It being further improved, the shell is made of stainless steel, carbon fiber or resin material, wear-resisting, and intensity is high, good toughness,
It is not easy corrosion.
Compared with prior art, the utility model has the beneficial effects that：
1, by by shell it is seperated with driving drum design, as long as periodic replacement shell, without replace driving drum,
Substantially reduce cost.
2, shell is double-body bike, is easily installed, dismantles, and conducive to processing.
3, rough and uneven in surface by the way that surface of shell to be designed as, the contact surface of shell and pipeline internal ratio is increased, friction is increased
Power prevents from skidding, and improves driveability.
4, anti-skid chequer is provided with by the top surface in helical blade, prevents skid, increase frictional force.
