Abstract

The utility model provides an elevating on and off machine mainly for opening and closing a hydraulic gate. A column reel drum arranged on an ordinary elevating on and off machine is converted into a reel drum form (7) with a multi-layer winding structure, and thereby, the utility model can accommodate a rule that a door opening force is changed from large to small as the addition of the opening of the door opening force, the gate is opened from low speed to high speed, and the on and off machine works in the state of equal output power fundamentally can be realized simply. Thereby, the door opening ability of the on and off machine is improved obviously.

Description

Rolling open and close machine

The utility model relates to the opening and closing device field, is specifically related to the plant equipment that elevator opens and closes hydraulic gate.

In the prior art, rolling open and close machine is mainly by motor, brake, reducer, large and small open travelling gear, winding plant, wire rope, movable and fixed pulley group, compositions such as frame.Work as starter motor, reel lay winding wire ropes starting gate.Its reel all is an employing garden post reel, and the wire rope winding of single layer, and double-deck at the most the winding is with certain speed lift gate at the uniform velocity.The design consideration of headstock gear opens a speed and opens a power outfit power power by maximum, and members such as deceleration that power therewith adapts, transmission, supporting are set, and open Men Li is significantly reduced along with the increase of gatage, and it is that minimum the termination opened more than the twice of a power that its amplitude of variation maximum initially opens Men Li.Therefore, in whole gate opening process, the power output of headstock gear is descending, fail to make headstock gear under power output state such as basic, to work, cause disposing excessive power power, and members such as bigger deceleration that power therewith adapts, transmission, supporting are set, thereby the energy and raw material have been wasted.

The purpose of this utility model provides a kind of rolling open and close machine, and realization headstock gear that can be easy is worked waiting under the power output state substantially.

The utility model solution is the reel of the winding plant of common rolling open and close machine to be arranged to the reel of multi-lay winding structure.During work, wire rope at first begins to twine from bottom, with than the low velocity starting gate, to adapt to a bigger first power that opens; Increase along with gatage, opening Men Li descends gradually, and lifting-speed increases gradually along with the increase of twining the number of plies, thereby gate speed change in whole opening process is promoted, by the suitable winding number of plies is set, coincide so that open the variation of the variation of a speed and Qi Menli, it opens a power demand and maintains substantially near the performance number that needs when opening beginning.Realized that headstock gear works waiting under the power output state substantially.

Owing to adopted the reel of multi-lay winding structure in the above-mentioned solution, easy realization the constant power output of headstock gear, the utility model is compared with existing rolling open and close machine has following advantage.

1, identical if be equipped with power, then can significantly improve a speed that on average opens.

2, identical if on average open a speed:

(1) being equipped with power power can significantly reduce;

(2) each deceleration, transmission, specification, the size of members such as supporting greatly reduce.

(3) whole bridge lock electric distribution network capacity can significantly descend.

Fig. 1 is the vertical view of rolling open and close machine.

Fig. 2 is the longitudinal sectional view of winding plant.

Fig. 3 is the front view of rolling open and close machine.

Below in conjunction with embodiment the utility model is described in further detail.

As Fig. 1, Fig. 3, shown structure is on the basis of the form of structure of common rolling open and close machine, garden post reel is become the reel of multi-lay winding structure.Its transmission principle is motor (1), by electromagnetic brake (2), enter reducer (3), the pinion that reducer output shaft is installed (4), be meshed with the gear wheel (6) that connects with the reel (7) of multi-lay winding structure, the reel of multi-lay winding structure is by the wire rope (8) of movable and fixed pulley group (5), by low speed to high speed speed change starting gate.Gate is closed by deadweight.

Its structure of reel of the multi-lay winding structure of above-mentioned rolling open and close machine as shown in Figure 2.It is mainly by terminal pad (10), wire rope canned paragraph (11), and left back-up ring (12) twines section (13), right back-up ring (14), wheel hub (15), wheel bore (16), wire rope inclined perforation (17) is formed, and it is characterized in that, the two ends of twining section (13) are provided with wire rope back-up ring (12), (14).Reel is provided with the changing value decision of the number of plies by Qi Menli.Generally be advisable more than 5 layers.

Reel terminal pad (10) connects with gear wheel (6), and by wheel bore (16), axle sleeve (16) is bearing on the spool shaft (19), and an end of wire rope (8) is worn to fixed end by oblique perforation (17) and to be fixed.During work, gear wheel drives the reel rotation, and wire rope begins to twine from bottom, change winding direction and enter high level, the every increase one deck of wire rope, the corresponding increase of its coiling diameter by back-up ring, speed of wrap improves, thereby realizes the basic constant power output of headstock gear with suitable speed change.

Certainly, the reel of above-mentioned multi-lay winding structure also can be combined into multi-lay winding structure double crosslinking drum, and the form of structure of headstock gear also can correspondingly be made variation.
