Abstract

The utility model relates to a swing type screw rod gate hoist which belongs to the technological field of controlling mechanical equipment. The technical problem to be solved is to provide an economic and practical swing type screw rod gate hoist of compact and reasonable structure and safe and reliable operation. The technical points are: a swing supporting mechanism (4), comprising a connecting block (41), an upper supporting plate and a lower supporting plate (42, 43) and a shaft (44) connecting the upper and the lower supporting plates, is arranged between a die (2) and a frame (5). The swing supporting mechanism is added, so the die part of the gate hoist is able to swing back and forth and a swinging angle can be over 90 degrees, meeting the demand that a lifting point rotates along a gate supporting point and that a lifting centerline swings back and forth when an arc gate is opened and closed. Meanwhile, the screw rod can be directly connected with a hanging head of the gate without the need to add a guide rail device, and no frictional resistance or guiding component force exists. The open and close force of the gate hoist is constant, and the operation is stable and reliable; in addition, the swing type screw rod gate hoist has no special requirement for civil construction, thus saving civil construction investment.

Description

The swing type screw open-close machine

Technical field:

The utility model relates to a kind of open/close machinery that is used to control the water conservancy gate opening/closing, particularly a kind of swing type screw open-close machine that is applicable to that the water conservancy Segment gate opens and closes.

Background technology:

At present, winch hoist is selected in the keying that is used for the water conservancy Segment gate usually for use, winch hoist by wire rope roll around the rising that can drive Segment gate, but gate must rely on deadweight that a power of closing is provided, under the situation of big head, use, have only the weight that increases gate or add balance weight iron and increase a power of closing, can provide a bigger power of closing though increase the cost and the also undesirable use general expression of the result of use worm-type open-close machine of whole engineering, but headstock gear must be placed in gate hang head directly over or the place ahead, so just increased the construction investment of dam; Transmission mechanism also will install the complicated guide rail slide block device of a cover additional simultaneously, owing to be subjected to the friction of guide rail slide block, and the influence of guide rail guiding component, causing worm-type open-close machine to provide hoisting capacity to have greatly consumes on idle work, and gatage is big more, the angle of gate connecting rod and screw rod is big more, and effective hoisting capacity that headstock gear provides is just more little.Therefore, the headstock gear that opens and closes the arc door will be selected more large-tonnage screw open-close machine for use, not only increased investment cost, and the hoisting capacity that screw open-close machine provides is change constantly, the screw rod of headstock gear is worked under this mechanical model, fatigue phenomenon takes place easily, thereby greatly reduces the application life of screw open-close machine.

Summary of the invention:

Technical problem to be solved in the utility model is: provide a kind of compact conformation reasonable, safe and reliable to operation, the complete machine superior performance, simple to operation, economical and practical its technical scheme of swing type screw open-close machine is: a kind of swing type screw open-close machine, comprise screw rod head transmission mechanism and frame, it is characterized in that: be provided with between described head and the frame by the contiguous block upper and lower support plate and with its technique effect of swinging mounting mechanism that constitutes of axle that is connected upper and lower support plate be: this swing type screw open-close machine is owing to increased swinging mounting mechanism, make the headstock gear head section can realize swing, pendulum angle can be greater than 90 degree, satisfied when opening and closing Segment gate, the Heave Here is propped up angle point along gate and is rotated, lift by crane the requirement of center line swing, be specially adapted to the keying of deep hole Segment gate; Simultaneously, screw rod can directly be connected with the head that hangs of gate, and the centre does not need to set up track-type facilities, there are not any frictional resistance and guiding component, the headstock gear hoisting capacity is constant, and operate steadily reliable and gate firm and reliable connection help reducing Segment gate vibration in the opening-closing process under moving water condition; In addition, this swing type screw open-close machine does not have specific (special) requirements to civil engineering, can save construction investment according to on-the-spot civil engineering actual conditions, it is arranged in all can Anywhere of gate top, solve other type and can not behind the dam, the restriction of mounting arrangements be equipped with special-purpose travel control device, also can accurately measure the headstock gear screw stroke, and be converted into gatage and show, bound in gatage is provided with the limit induction switch, to guarantee that gate safety in predetermined stroke opens and closes, and realizes the remote automation control of gate.

Description of drawings:

Fig. 1 is the utility model structural representation;

Fig. 2 is the utility model user mode schematic diagram.

The specific embodiment:

As shown in figure 12, the swing type screw open-close machine is made up of between transmission mechanism 3 and the head 2 screw rod head transmission mechanism and frame and is passed through worm screw, worm gear connects, fixing nut is threaded to be provided with between head and the frame 5 by contiguous block 41 upper and lower support plates 4243 with screw rod 1 and is fixed on the contiguous block with axle 44 swinging mounting mechanism 4 heads and the transmission mechanisms that constitute that are connected upper and lower support plate on the worm gear in the head, two of contiguous block is fixed a bottom respectively and is had the corresponding lower supporting plate 43 of upper backup pad on fixing respectively and the contiguous block on upper backup pad 42 frames 5 of axis hole, the top of lower supporting plate also has axis hole, by axle 44 contiguous block and frame are passed in the lower end of the hinged screw rod of upper and lower support plate, 6 directly be connected with hanging of gate.

Claims

1. swing type screw open-close machine, comprise screw rod head transmission mechanism and frame, it is characterized in that: be provided with by contiguous block (41), upper and lower gripper shoe (42,43) between described head (2) and the frame (5) and be connected the swinging mounting mechanism (4) that the axle (44) of upper and lower gripper shoe constitutes.
