Abstract
The utility model discloses a double-jacking screw hoist, which comprises hoist heads (1), screws (2), hanging bases (3) and a gate (4), wherein the hoist heads (1) are connected with the screws (2). The double-jacking screw hoist is characterized in that two sets of the hoist heads (1) and the screws (2) are symmetrical right and left; embedded pipes (5) are arranged below the screws (2); the screws (2) are inserted into the embedded pipes (5) in a movable mode; a beam (6) is connected above the screws (2); pull rods (7) are connected to the middle of the beam (6); the lower ends of the pull rods (7) are connected with the gate (4) by the hanging bases (3); and a synchronizing shaft (8) is arranged between the two hoist heads (1). According to the double-jacking screw hoist, due to the arrangement of the embedded pipes, when the gate is closed, the screws are positioned underground; and when the gate is opened, one section, which is exposed out of the ground, of each of the screws which move upwards is blocked by the beam, so that the attractive appearance is not influenced. In addition, the beam is jacked by arranging the two screws, and the gate is pulled by arranging the two pull rods on the beam, so that the running stability of the gate is improved, and an opening effect is good.
Description
Technical field
The utility model belongs to a kind of headstock gear, is a kind of worm-type open-close machine particularly.
Background technology
At present, the gate and the supporting headstock gear thereof that are applied in the Hydraulic and Hydro-Power Engineering to keep off, arrange, pour water are of a great variety, and pattern is different.Especially worm-type open-close machine is cheap because of it, install and use easy to maintenance, the applied more and more in middle-size and small-size hydraulic engineering.At present, common screw open-close machine includes: open and close head, screw rod, pull bar, flap seat, gate, open and close head and all be positioned on the ground with screw rod, keying head drive screw moves up and down, and the screw rod cylinder lever connecting rod also gate through the flap seat band and moved up and down.The deficiency of its existence is: the one, and the lift gate operation is not steady, causes eastern askew west oblique; The 2nd, screw rod is high be exposed to above, cause very high obstacle on ground, both influenced attractive in appearancely, also make troubles to people.Therefore often will set up frame bridge and headstock gear, this causes very big investment to the builder again, has improved use cost.
Summary of the invention
The purpose of the utility model is to overcome the above-mentioned deficiency of prior art, and a kind of improved headstock gear is provided, and its structure is provided with rationally, installs and uses easy to maintenancely, attractive in appearance, operates steadily, and result of use is good.
For reaching above-mentioned purpose; The utility model is taked following technical scheme: the utility model includes: open and close head, screw rod, flap seat, gate; Opening and closing head connects with screw rod; It is characterized in that: opening and closing head and screw rod is bilateral symmetry two covers, is provided with pipe laying corresponding to the screw rod below, and the screw rod activity inserts in the pipe laying; The screw rod top is connected with crossbeam, and the crossbeam middle part is connected with pull bar, and the pull bar lower end connects gate through flap seat.
The utility model is taked technique scheme, has following beneficial effect: when the utility model used, it is underground that two pipe layings place, and screw rod inserts in the pipe laying.Two keying heads order about screw rod and in pipe laying, move up, and the crossbeam at screw rod top moves up thereupon, move on the pull bar pulling gate.The utility model is owing to be provided with pipe laying, and when closing, screw rod is positioned at underground, moves on during unlatching and bassets one section, and have crossbeam to block, and can not influence attractive in appearancely, can not cause too many inconvenience to people.In addition, the utility model can be installed two pull bars and spur gate because two screw rod jack-up crossbeams are set on the crossbeam, like this, improved the gate traveling comfort, opens better effects if.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is elaborated:
Fig. 1 is the structure diagram of the utility model embodiment.
Mark among the figure: 1-opens and closes head, 2-screw rod, 3-flap seat, 4-gate, 5-pipe laying, 6-crossbeam, 7-pull bar, 8-synchronizing shaft.
The specific embodiment
By shown in Figure 1; The utility model includes: open and close head 1, screw rod 2, flap seat 3, gate 4, open and close head 1 and connect with screw rod 2, it is characterized in that: open and close head 1 and be provided with bilateral symmetry two covers with screw rod 2; Be provided with pipe laying 5 corresponding to screw rod 2 belows, screw rod 2 activities insert in the pipe laying 5; Screw rod 2 tops are connected with crossbeam 6, and crossbeam 6 middle parts are connected with two pull bars 7, and pull bar 7 lower ends connect gate 4 through flap seat 3.
The utility model is the synchronous operation of guaranteeing two screw rods 2, opens and closes between the head 1 at two and is equiped with synchronizing shaft 8.
Claims (2)
1. dual-top type screw open-close machine; It includes: open and close head (1), screw rod (2), flap seat (3), gate (4); Opening and closing head (1) connects with screw rod (2); It is characterized in that: open and close head (1) and overlap for bilateral symmetry two with screw rod (2), be provided with pipe laying (5) corresponding to screw rod (2) below, screw rod (2) activity inserts in the pipe laying (5); Screw rod (2) top is connected with crossbeam (6), and crossbeam (6) middle part is connected with pull bar (7), and pull bar (7) lower end connects gate (4) through flap seat (3).
