Abstract
The utility model discloses an over-torsion protection mechanism of a mud sucker and scraper, which has an elastic body over-torsion protection device being disposed on a driving stent and a shell of a reducer. When the mud sucker and scraper works, walking steel wheels produce the counterforce to the reducer for controlling the compression volume of the elastic body. When the mud sucker and scraper bears the supernormal loading force, the deformation value of the elastic body exceeds the switch position for controlling the switch and cutting off the power supply so as to play the protection role. When the malfunction is excluded, the elastic body is restored for startup again. The utility model is characterized by simple and reliable structure, convenient usage and long service life.
Description
Technical field
The utility model relates to a kind of suction mud scraper that is used for sewage disposal, especially inhales the torque protection device of crossing of mud scraper.
Background technology
Along with the industrial develop rapidly of China, the generation of waste gas sewage grows with each passing day, and therefore, the protection environment is handled waste gas sewage well and also more and more is subjected to the attention of central authorities to local governments at various levels.Inhaling mud scraper is the main equipment that is used for sewage disposal, how safety, make to make good use of and inhale mud scraper and examine one of problem of Account reliably with regard to having become the planner.The step-down gear of the suction mud scraper of prior art adopts cycloidal planetary gear speed reducer, adopt between its output shaft and the driving wheel shaft coupling connects ， And with shearing pin as the mistake torque protection.Do the time spent when the driving wheel of inhaling mud scraper is subjected to extraordinary external force, shearing pin is sheared power and destroys, and plays the effect of protection driving mechanism.The problem of its existence is: when shearing pin is sheared power and destroys, shaft joint also is damaged, should changes shearing pin like this, change shaft joint again, improved production cost, also increased maintenance load, also influence the water treatment progress; Simultaneously owing to adopt the cycloidal-pin wheel speed reduction unit, must use shaft coupling to connect between its output shaft and the driving wheel, its technology shortage sense of modernness, there be limited evidence currently of employing.
Summary of the invention
The deficiency of aspects such as the utility model mainly is to solve the operation inconvenience that exists in the prior art, and work-ing life is short, and maintenance load is big.
In order to solve the problems of the technologies described above; agent technology scheme of the present utility model is: it contains driving arm the torque protection device excessively of described suction mud scraper; electrical control system; be installed in the step-down gear on the driving arm, it is characterized in that: on reducer shell and driving arm, elastomerics is installed and crosses torque protection device.
As preferably; it is that housing at step-down gear tightens a pivot pin that described elastomerics is crossed torque protection device; be with spring on it; the end has contactor segment and spring fastening; be with the cylindrical shell that an end is fixed on the driving arm, the end is sealed outside it; the cylindrical shell the other end closely contacts with spring, and an end of contactor segment exposes to the opening part of cylindrical shell, is equipped with near switch with the corresponding position of contactor segment on the cylindrical shell.
Described elastomerics except that spring, can also be rubber or soft plastics elastomeric material.
The beneficial effects of the utility model are: owing to adopted elastomerics to cross torque protection device, so reliable in structure, easy to operate, and long service life, the problem that mud scraper is in operation and causes driving mechanism to damage because of overload of inhaling solved effectively.

Specific embodiments
As Figure 1-3: 1 is drive unit, and 2 is drive chassis, and 3 is slag discharging device, and 4 is sludge collector structure and suction dredger structure, and 5 is service bridge, and 6 is center support, and 7 is electrical control system, and 8 cross torque protection device for elastomerics.
Shown in Fig. 4-6: the housing of crossing torque protection device and being at step-down gear 9 tightens a pivot pin 16; be with spring 14 on it; the end of spring has contactor segment 12 to make its tight contact; it is outer to be with an end and to be fixed on cylindrical shell 11 on the driving arm 2; the other end of cylindrical shell 11 covers ， And with stifle 17 and closely contacts with spring, and there is governing screw in the outside; one end of contactor segment 12 exposes to the opening part of cylindrical shell 11, and cylindrical shell 11 is equipped with near switch 13 with the corresponding position of contactor segment.
Described also can be signal elements such as travel switch, contactor near switch 13.Consider from protection, shield cap 15 can be installed at the opening of cylindrical shell 11 and near the position between the switch 13.
When inhaling mud scraper work, 10 pairs of step-down gears of walking steel wheel 9 produce a reactive force, the draught of control spring 14.If when the suction mud scraper was worked under rated load, its moment of torsion was less than setting valve, the draught of spring 14 does not reach near switch 13 positions, and protector is failure to actuate; When the driving mechanism of inhaling mud scraper is subjected to extraordinary loading action, the over proof setting valve of moment of torsion, then spring 14 distortion increase, and have met or exceeded near switch 13 positions, and near switch 13 actions, trip switch is with power dump.After Dai Jian Cha And fixed a breakdown, elastomerics resetted, and electrical control system restarts.
