Abstract
The invention discloses a vertical-shaft driving device of a centrally-driven mud scraper and relates to a driving device of a centrally-driven mud scraper for a sedimentation tank in a sewage treatment plant. The driving device comprises a piston push rod, a support seat of the piston push rod, a ratchet mechanism and a rotary support seat with a ratchet wheel, wherein the ratchet mechanism consists of a rotary arm, a pull spring and a ratchet; one end of the rotary arm is fixed on a central shaft of the rotary support seat with the ratchet wheel, and the other end of the rotary arm is hinged with the piston push rod on the outer side of the ratchet wheel; the ratchet arranged on the rotary arm is prepressed onto the surface of the ratchet wheel through the pull spring; and one end of the pull spring is fixed on the rotary arm, and the other end of the pull spring is fixed on the ratchet. The device has a simple structure, a small number of machine members, high work efficiency, adjustable speed and low energy consumption, does not generate noise, runs stably and is easy to maintain.
Description
Technical field
The present invention relates to the drive unit of sewage treatment plant's sedimentation basin center transmission mud scraper, specifically a kind of drive unit that is used for suspension type center transmission mud scraper.
Background technology
The drive unit that is used for transmission mud scraper in center in the prior art, all be motor through multistage combination deceleration transmission such as chain transmission, gear (or worm and gear) casees, make king drive the traditional mode that scraping arm and cleaning shoe rotate.As Chinese patent application CN200810111132.6 and 200720098248.1 disclosed center transmission mud scrapers, its drive unit is the form of cycloid in planet gear drive.Because the operating rate of mud scraper is very low, the moment of transmitting is bigger, and the kind of drive that adopts multi-stage gear case and chain transmission etc. to slow down step by step causes the volume of drive unit big, the deadweight of complex structure, body is heavier, and transmission efficiency is lower, and installation and maintenance load are bigger.
Summary of the invention
The object of the present invention is to provide the drive unit of a kind of vertical shaft type center transmission mud scraper, it has overcome deficiency of the prior art, and characteristics are that driving mechanism structure is simple, and installing space is little, the transmission efficiency height.Main innovation is not adopt gear reduction motor or multi-stage speed-reducing mechanism but adopts piston push rod to drive sour jujube tooth mechanism rotating ratchet and drives vertical shaft and wholely scrape the rotation of mud system, and cleaning shoe adopts intermittent move mode, does not influence the spoil disposal function of sedimentation basin.
To achieve these goals, technical scheme of the present invention is: the drive unit of a kind of vertical shaft type center transmission mud scraper, the pivoting support seat that comprises piston push rod and bearing thereof, sour jujube tooth mechanism, band ratchet, it is characterized in that sour jujube tooth mechanism is made up of cursor, extension spring and sour jujube tooth, cursor one end is fixed on the central shaft of the pivoting support seat of being with ratchet, the other end is hinged with the piston push rod that is positioned at the ratchet outside, the sour jujube tooth that is installed on the cursor is pressed in ratchet surface in advance by extension spring, described extension spring one end is fixed on the cursor, and the other end is fixed on the sour jujube tooth.Piston push rod is done reciprocating in impulse stroke, when push rod stretches out forward, drive the sour jujube tooth motion on the sour jujube tooth mechanism cursor, and the ratchet increment is subjected to the thrust of sour jujube tooth, and king is rotated with the ratchet on the pivoting support seat; When push rod was withdrawn backward, the sour jujube tooth on the sour jujube tooth mechanism cursor relied on the restoring force of extension spring to enter next ratchet, with this periodic duty along the cambered surface slippage of ratchet.This driving mechanism structure is simple, and the rotating speed of vertical shaft is not subjected to the control of speed reducing ratio, does not need multi-stage speed-reducing mechanism combined, installing space is little, the transmission efficiency height, and cleaning shoe is done intermittently to move with piston push rod, the precipitation that helps mud does not influence the spoil disposal function of sedimentation basin.
Piston push rod of the present invention and sour jujube tooth mechanism can be provided with the 1-3 group, and each group evenly distributes, the pivoting support seat of a shared cover band ratchet.During operation, the piston push rod stroke is interlaced, carries out interlock, moves more steadily, and operating efficiency is higher.
Driving mechanism structure of the present invention is simple, and parts are few, operate steadily, and noiseless, high efficiency, adjustable-speed, the saving energy is safeguarded comparatively simple and easy.

The specific embodiment
The drive unit of a kind of vertical shaft type center transmission mud scraper, the pivoting support seat 3 that comprises two groups of piston push rods 1 and bearing thereof 11, two groups of sour jujube tooth mechanisms 2, one group of band ratchet, each organizes piston push rod 1 and sour jujube tooth mechanism 2 evenly distributes, the pivoting support seat 3 of a shared cover band ratchet.Sour jujube tooth mechanism 2 is made up of cursor 21, extension spring 22 and sour jujube tooth 23, cursor 21 1 ends are fixed on the central shaft 32 of the pivoting support seat 3 of being with ratchet 31, the other end is hinged with the piston push rod 1 that is positioned at ratchet 31 outsides, the sour jujube tooth 23 that is installed on the cursor 21 is pressed in ratchet 31 surfaces in advance by extension spring 22, described extension spring 22 1 ends are fixed on the cursor 21, and the other end is fixed on the sour jujube tooth 23.
Annotate: according to processing requirements, piston push rod in this device and sour jujube tooth mechanism can be arranged to the 1-3 group.
Claims (2)
1. the drive unit of a vertical shaft type center transmission mud scraper, the pivoting support seat that comprises piston push rod and bearing thereof, sour jujube tooth mechanism, band ratchet, it is characterized in that sour jujube tooth mechanism is made up of cursor, extension spring and sour jujube tooth, cursor one end is fixed on the central shaft of the pivoting support seat of being with ratchet, the other end is hinged with the piston push rod that is positioned at the ratchet outside, the sour jujube tooth that is installed on the cursor is pressed in ratchet surface in advance by extension spring, described extension spring one end is fixed on the cursor, and the other end is fixed on the sour jujube tooth.
