Abstract
The utility model provides a pushing double-rod rack hoist, which includes a housing and drive gear sets and rod racks matched with the drive gear sets that are arranged in the housing, wherein the housing includes a housing I and a housing II; both the housing I and the housing II are provided with the drive gear sets and the rod racks matched with the drive gear sets respectively; the rod racks penetrate the housing I and the housing II respectively; the upper ends of the two rod racks are connected with a bracket respectively; the other end of the bracket is connected with a gate; and an output shaft with a drive device is connected with a speed reducer, the output shaft of the speed reducer is connected with the power input shaft of the drive gear set in the housing I, and the other end of the power input shaft in the housing I penetrates the housing I and is connected with the power input shaft of the drive gear set in the housing II through a coupler. The power device drives the drive gear sets in the housing I and the housing II, and the drive gear sets drive the two rod racks and the bracket connected with the rod racks to ascend or descend, so as to open/close the gate. The pushing double-rod rack hoist has simple integral structure and low use cost.
Description
Technical field
The utility model relates to a kind of headstock gear, especially a kind of push mode bidentate bar headstock gear.
Background technology
At present, in hydraulic engineering, generally adopt worm-type open-close machine to drive gate opening/closing.During headstock gear work, the power set drive screw drives gate and rises or descend on working platform, thereby realizes the keying of gate.But this gate opening/closing mode needs the working platform above the gate hoisting depth, its long construction period, and use cost is high.Existing in prior technology weak point that Here it is.
Summary of the invention
The technical problem that the utility model will solve is exactly not enough to existing in prior technology, and a kind of simple in structure, push mode bidentate bar headstock gear that use cost is low is provided.
This programme is realized through following technical measures: this push mode bidentate bar headstock gear comprises drive gear set in casing and the casing and the ratch that cooperates with drive gear set; Said casing comprises casing one and casing two; The ratch that is respectively arranged with drive gear set in casing one and the casing two and cooperates with drive gear set; The upper end that ratch passes casing one and casing two, two ratch respectively is connected with support respectively, and the other end of support links to each other with gate; There is the output shaft of drive unit to be connected with reductor; The power input shaft of drive gear set is connected in said speed reducer output shaft and the casing one, and the other end of the power input shaft in the said casing one passes casing and is connected through the power input shaft of the interior drive gear set of shaft coupling and casing two in the lump.
Also have the jaw opening sensor that aperture shows on the said machine casing two, the aperture that is used for Segment gate shows.
Above-mentioned drive unit is motor or hand-operated mechanism, can select flexibly according to the operation needs.
The beneficial effect of this programme can be learnt according to the narration to such scheme; In this push mode bidentate bar headstock gear; Casing comprises casing one and casing two, and the ratch that is respectively arranged with drive gear set in casing one and the casing two and cooperates with drive gear set, ratch pass casing one and casing two respectively; The upper end of two ratch is connected with support respectively, and the other end of support links to each other with gate; There is the output shaft of drive unit to be connected with reductor; The power input shaft of drive gear set is connected in said speed reducer output shaft and the casing one, and the other end of the power input shaft in the said casing one passes casing and is connected through the power input shaft of the interior drive gear set of shaft coupling and casing two in the lump.Power set drive the drive gear set in casing one and the casing two, and drive gear set drives two ratch and reaches the support rising that links to each other with ratch or descend the keying of realization gate.This headstock gear does not need the cement work platform, and overall structure is simple, and use cost is low.This shows that the utility model compared with prior art has substantive distinguishing features and progress, the beneficial effect of its enforcement also is conspicuous.
Description of drawings
Fig. 1 is the structural representation of the utility model specific embodiment.
Among the figure, 1 is motor, and 2 is ratch, and 3 is reductor, and 4 is shaft coupling, and 5 is that casing one, 6 is that casing two, 7 is a jaw opening sensor, and 8 is power input shaft, and 9 is power input shaft, and 10 is support, and 11 is gate.
The specific embodiment
For clearly demonstrating the technical characterstic of this programme, below through the specific embodiment, and combine its accompanying drawing, this programme is set forth.
A kind of push mode bidentate bar headstock gear; As shown in Figure 1, it comprises drive gear set in casing and the casing and the ratch 2 that cooperates with drive gear set, and said casing comprises casing 1 and casing 26; The ratch 2 that is respectively arranged with drive gear set in casing 1 and the casing 26 and cooperates with drive gear set; The upper end that ratch 2 passes casing 1 and casing 26, two ratch 2 respectively is connected with support 10 respectively, and the other end of support 10 links to each other with gate 11; There is the output shaft of drive unit (like motor 1 or hand-operated mechanism) to be connected with reductor 3; The output shaft of said reductor 3 is connected with the power input shaft 8 of drive gear set in the casing 1; The other end of the power input shaft 8 in the said casing 1 passes casing 1 and the power input shaft 9 through the drive gear set in shaft coupling 4 and the casing 26 is connected, and also has the jaw opening sensor 7 of aperture demonstration on the casing 26.
Power set drive corresponding ratch 2 through casing 1 with casing 26 interior drive gear set and rise simultaneously or descend, and ratch 2 drive supports 10 and the gate 11 that links to each other with support 10 rise or descend, thus the keying of realization gate 11.
Can pass through existing techniques in realizing without the technical characterictic of describing in the utility model, repeat no more at this.
