Description
The utility model relates to a kind of spoil disposal machinery, particularly a kind of reciprocating type diving mud scraper that is applicable to rectangle settling tank and tube settler spoil disposal.
In water factory and sewage disposal, because the difference of suspended substance character, content and pond shape, all kinds of spoil disposal machineries all exist certain limitation, particularly suction dredger.Particle contained in water is too much, proportion is bigger, the turbidity height, easily harden, water such as Upper Yangtze River, if suck up with suction dredger, relatively more difficult, and inhomogeneous heavy mud in the pond, it is inconsistent to inhale mud concentration, the water ratio height of sucking-off mud, waste water, for this reason, the applicant is space car formula cantilever mud scraper on probation in the rectangle tube settler of this type of water factory once, it is fixed on pin rack on the bay wall, drive unit is installed on the end carriage, and when scraping the motion of mud car, drive unit is along with motion, connect with the side truss between end carriage and the following case bay, the deadweight of whole mud scraper is to bear on the road wheel of end carriage, and therefore, side truss and following truss are in suspended state, because load is repeated load, when load was uprushed, side truss and following truss may produce flexural deformation, and undergear and pin tooth engagement position are to produce the maximum position of flexural deformation, cause the concentricity of gear position and support bearing portion axle to increase, gear and the engagement of pin tooth are bad, cause noise to increase, therefore through facts have proved, there are two problems in this running type cantilever mud scraper: 1. complex structure, the huge heaviness of truss; 2. gear, pin tooth engagement are bad, influence transmission accuracy.
It is a kind of simple in structure that the purpose of this utility model is to provide, the reciprocating type diving mud scraper of stable transmission.
The utility model is achieved in that a kind of reciprocating type diving mud scraper, and it comprises drive unit, transmission rig, scrape the mud car, guide deflection sheave, position-limit mechanism, electric appliance control box is characterized in that: described drive unit is made up of motor, step-down gear, and is fixed on the settling tank face through support; The transmission rig that links to each other with step-down gear is made up of transmission shaft, transmitting gear, and it is fixed on the pool wall through resting support; Place the mud car of scraping at the bottom of the settling tank to be made up of pin rack, cleaning shoe, colter, road wheel and truss, wherein pin rack is meshed with transmitting gear.
Above-mentioned guide deflection sheave is fixed on the precipitation pool wall, and contacts with the edge rolling of scraping the mud car, play the guiding role during operation; Scrape mud car below and establish track, the road wheel of scraping the mud car travels in orbit.
The control that is connected with electric appliance control box of the above-mentioned position-limit mechanism that is located in the support.
Above-mentioned step-down gear adopts cycloidal planetary gear speed reducer.
When the settling tank degree of depth considerably beyond a propeller shaft length, cause when scraping the mud car and can not place at the bottom of the pond, can several propeller shaft couplings be fixed by clamping coupling.
The utlity model has following advantage:
1. the utility model has been cancelled last truss and side truss, and road wheel is put into by Yuan Chimian at the bottom of the pond, and whole truss design is simpler than original structure, small and exquisite, saves material, has therefore alleviated weight greatly;
2. the utility model is fixed on Chi Mianshang with drive unit, when Installation and Debugging, is convenient to control the concentricity of lower shaft, has guaranteed gear-driven positional precision, has eliminated the influence of mud scraper vibration to it;
3. the utility model is provided with fixed supporting frame on the transmission shaft of the upper-lower position of close gear, has limited the flexural deformation of gear shaft, has guaranteed the transmission stability of mud scraper;
4. the utility model is except that electric machine stand, and mud scraper truss main body is all under water potential, and rust cleaning paint maintenance workload and expense reduce, and because the driving mechanism stationkeeping has reduced cable handler, have saved investment;
5. transmission rig of the present utility model adopts the transmission of pin tooth under water, and overload capacity is big, and upsetting moment is little.
The utility model is described in further detail below in conjunction with drawings and Examples:
Fig. 1: the structural representation of the utility model embodiment 1.
Fig. 2: the vertical view that is Fig. 1;
The A-A cutaway view Amplified image of Fig. 3: Fig. 2;
Fig. 4: the electrical schematic that the utility model electric appliance control box is adopted.
Referring to Fig. 1～3 as can be known: a kind of reciprocating type diving mud scraper, it comprises drive unit, transmission rig, scrape the mud car, guide deflection sheave 13, position-limit mechanism 3, electric appliance control box 17 is characterized in that: described drive unit is made up of motor 1, step-down gear 2, and is fixed on the settling tank face through support 4; The transmission rig that links to each other with step-down gear 2 is made up of transmission shaft 5, transmitting gear 8, and it is fixed on the pool wall through resting support 7; Place the mud car of scraping at the bottom of the settling tank to be made up of pin rack 9, cleaning shoe 11, colter 14, road wheel 10 and truss 15, wherein pin rack 9 is meshed with transmitting gear 8.
Above-mentioned guide deflection sheave 13 is fixed on the precipitation pool wall, and contacts with the edge rolling of scraping the mud car; Scrape mud car below and establish track 16, the road wheel 10 of scraping the mud car travels on track 16.
Above-mentionedly be located at position-limit mechanism 3 in the support 4 by electric appliance control box 17 control that is connected.
Above-mentioned step-down gear 2 adopts cycloidal planetary gear speed reducer.
In Fig. 1, it can also be seen that: be connected and fixed by clamping coupling 6 between transmission shaft 5 and the transmission shaft 5.
Referring to Fig. 4 as can be known: photoelectricity position-limit mechanism 3 is located in the support 4, the shading baffle plate is housed on the transmission shaft 5, when transmission shaft 5 rotates, the shading baffle plate periodically interdicts photoelectric limit switch 3, and the output photoelectric pulse signal, send into adjustable presetting in the add, make addition (or subtraction) counting, when reaching, presets when several counting, counter output signal is through power magnification rear drive 2ZJ (or 3ZJ) action, and mud scraper is made inverted running, at this moment, counter subtract (or addition) counting, in like manner, when arriving, counter presets when several 3ZJ (or 2ZJ) action, mud scraper is made inverted running once more, thereby reaches the control that mud scraper comes and goes operation.
