Abstract

The utility model relates to a gate hoist for opening and closing a water gate, and left and right two reel drums driven by an electric motor have synchronous rotation. The utility model is characterized in that a set of pulley wheel system composed of a movable pulley wheel and a fixed pulley wheel is designed between a reel drum and the gate, the movable pulley wheel is designed with a connecting element which is connected with the gate, one end of a steel cable is fixed on the reel drum, and the other end of the steel cable is fixed on a force measuring arm through the pulley wheel system. Thereby, the open-close force borne by the reel drum is reduced, one end of the force measuring arm is connected with a machine frame, the other end is connected with a pressure signal controller for measuring gate opening force or gate closing force when the gate is opened and closed, and the utility model can alarm and stop run under the condition of abnormal gate opening or closing force. The utility model is a novel gate hoist with small structure, and the utility model can prevent a large equipment accident because abnormal opening and closing force.

Description

Gate hoist

The utility model relates to a kind of sluice gate hoist.

Normally used gate hoist, its left side, right two reels directly are connected with two suspension centres of a fan sluice gate by wire rope respectively, the power of its motor after retarder slows down respectively through a left side, right transmission shaft drives a left side, right reel rotates, realize opening or closing of gate, but because gate is directly to connect by wire rope, the suffered power of reel is bigger, the hoist structure is huger, a hoisting capacity is 4.8 * 105 newton's a hoist, its hoist weight up to 17 tons about, cost of production is very high, therefore, in order to reduce investment, for the waterwork with porous gate, gate hoist normally is designed to portable, opens and closes many fan brakes door with a hoist, but owing to reasons such as installation precisioies, make gate when opening or close, opening Men Li or closing Men Li on last two wire rope of often same fan brake door differs bigger, and deflection takes place when opening or close gate, make the caulking gum skin generation inordinate wear of gate, thereby cause sluice seriously to leak.

The purpose of this utility model provides the less power of a kind of usefulness and realizes bigger hoisting capacity, when opening and closing gate, and the gate hoist that the hoisting capacity of two tie points on the same fan brake door equates substantially.

The purpose of this utility model realizes by following scheme:

Between the motor of gate hoist and retarder break is installed, motor, break and retarder are installed on the mid frame.Two output shafts of retarder connect Left Drive axle and right transmission shaft respectively, the gear engagement on gear on the Left Drive axle and the left reel, and left reel is installed on the left frame, is connected with mid frame upper reducer left side output terminal by the Left Drive axle.Gear on the right transmission shaft and the gear engagement on the right reel, right reel is installed on the right frame, is connected by the right output terminal of right transmission shaft and mid frame upper reducer.On left reel and right reel, be connected with wire rope respectively, and be equipped with on the left frame static pulley, movable pulley be connected by wire rope this static pulley below, be equipped with on the right frame decide cunning, movable pulley be connected by wire rope this static pulley below, design has a link that is connected with gate respectively on above-mentioned two movable pulleys; On left frame and right frame, also be separately installed with the dynamometry arm, on the dynamometry arm, be connected with wire rope and pressure signal controller.

Because the utility model designs between reel and gate by the pulley system of being made up of movable pulley and static pulley, make the hoisting capacity that bears on the reel less, realized finishing the purpose of big hoisting capacity with smaller and more exquisite structure, because the power of bearing on the hoist reel is less, hoist can design lessly, alleviated the weight of hoist, a hoisting capacity is 4.5 * 10 ⁵The utility model hoist of newton, only about about 4 tons of its weight is 1/4 of the present hoist weight of using, has reduced the cost of equipment; In addition, because design has dynamometry arm and a pressure signal controller, the hoisting capacity that bears on two reels can show and control that the gate that makes a fan open or close keeps evenly stressed by the pressure signal controller, guaranteed that deflection does not take place gate when opening or close, realized steadily opening or closing.When hoisting capacity generation abnormal conditions, report to the police automatically and shutdown, avoid the impaired substantial equipment accident of gate.

Below in conjunction with accompanying drawing in detail an embodiment of the present utility model is described in detail.

Figure 1 shows that the elevation view when the utility model is economized wire rope.

Fig. 2 is a plan view of the present utility model shown in Figure 1.

Fig. 3 is the utility model wire rope connection diagram shown in Figure 1.

Between motor of the present utility model [12] and the retarder [14] break [13] is installed, motor [12], break [13] and retarder [14] all are installed on the mid frame [22], retarder [14] has two output shafts, wherein an output shaft is connected with Left Drive axle [11], another root output shaft is connected with right transmission shaft [15], gear [23] on the Left Drive axle [11] and gear [10] engagement that is fixed on the left reel [7], left side reel [7] is installed on the left frame [3], static pulley [9] and dynamometry arm [4] also are installed on left frame [3], static pulley [9] is made up of two pulleys, five pulley rear ends that wire rope is walked around movable pulley [1] and static pulley [9] regularly are fixed on the dynamometry arm [4], one end of dynamometry arm [4] connects pressure signal controller [5], the other end is fixed on the left reel [7], and movable pulley [1] is connected with gate by link [2]; Gear [24] on the right transmission shaft [15] and gear [16] engagement that is fixed on the right reel [18], right reel [18] is installed on the right frame [19], static pulley [17] and dynamometry arm [4] also are installed on right frame [19], static pulley [17], movable pulley [21] is identical with movable pulley [1] structure with static pulley [9] respectively, right frame [19] goes up the dynamometry [4] of installing, pressure signal controller [5] is identical with the structure that left frame [3] is gone up installation, installation method is also identical, movable pulley [21] is connected left frame [3] by link [20] with gate, it is fixing that mid frame [22] and right frame [19] are all passed through stone bolt [6].The power of retarder [14] output terminal is passed to gear [23] and [24] through Left Drive axle [11] and right transmission shaft [15] respectively.When normally opening or closing, it is synchronous clockwise or be rotated counterclockwise that the power of motor [12] output drives left reel [7] and right reel [18] by Left Drive axle [11] and right transmission shaft [15] respectively, left and right two wire rope [8] are shortened simultaneously or extend, gate is promoted or puts down, and door extractor is proper functioning in specified hoisting capacity scope; If gate breaks down, the upper limit of hoisting capacity overrate or close the lower limit that Men Li is lower than rating value, at this moment, give the alarm by pressure signal controller [5], and cut off the electricity supply, break [13] braking, this gate hoist quits work, thereby has stopped the substantial equipment accident that gate takes place unusually because of hoisting capacity.In addition, can also pass through pressure signal controller [5] and go up the length that the situation of demonstration is in time adjusted left and right two wire rope [8], make the hoisting capacity that bears on left reel [7] and the right reel [18] equal substantially, stressed even when opening and closing gate with assurance.

The utility model can also be designed to integral body with left frame [3], mid frame [22] and right frame [19], is installed on the guide rail, becomes portable gate hoist.
