Abstract

The utility model relates to a single counterweight type balance gate structure. The gate can move upward and downward along guide posts at the two sides of the gate. Each side of the gate is provided with a counterweight; two steel ropes are respectively connected to the symmetrically right and the left terminals at the top end of the gate, whereas the other ends of the steel ropes are respectively twisted round a pulley group first and then tied to the top of the counterweight. The structure of the utility model ensures that no matter where the outer force point of the gate is positioned, the gate can be lifted or be lowered down in a balanced manner. Thus, compared with the prior art, the utility model has the beneficial effects of smooth opening or closing, compact structure, low cost and long service life, thus the utility model can be widely applied in the construction machines as nacelle gates, derrick outer gates, floor gats, host lift gates, cargo lift gates and warehouse gates and well gates in dock and industrial enterprises and mines.

Description

Single counterweight formula balance gate structure

Technical field

The utility model relates to building hoist tool technical field, particularly a kind of single counterweight formula balance gate structure that is used for various building hoist tools and industrial and mining enterprises warehouse.

Background technology

At present, in the building hoist tool, as hang blue, the derrick external door, the interlayer door, people's Cargo Lift gate and harbour, the warehouse gate of industrial and mining enterprises, well head gate etc. all is to adopt the heavy formula gate of biconjugate, its structure is referring to shown in Figure 1, article two,

wire rope

9,10 two ends lie in a left side respectively, right both sides counterweight 1,6 top and gate 8 top left, right two symmetry ends, wire rope 9 is by pulley 4,5 carry out guiding movement, wire rope 10 is by

pulley

2,3 carry out guiding movement, gate 8 can move up and down along the lead 7 of both sides, impose certain external force up or down by staff, just can realize the unlatching of gate or close.Not only structure is complicated, cost is higher for the heavy formula gate of above-mentioned biconjugate, and, the dispensing point of external force can not all drop in the central authorities of gate fully, so the unbalanced phenomenon of gate often appears in gate when opening or closing, gate blocks lead, and causes the lead easy deformation, thereby gate is opened or requires great effort very much when closing, increase operator's labour intensity, reduced operating efficiency.

Summary of the invention

In order to make gate lifting and the external force that imposes is not necessarily limited in the gate central authorities evenly, the utility model provides the single smoothly counterweight formula of a kind of keying balance gate structure.

Technical solution of the present utility model is such: a kind of single counterweight formula balance gate structure, comprise that gate, lead, wire rope, counterweight, pulley, gate can do upper and lower moving along the lead of its both sides, described two wire rope one ends lie in the left and right symmetry end in gate top respectively, and the other end of these two wire rope is walked around assembly pulley respectively and lain in a counterweight top.Described single counterweight is located at the left side or the right side of gate.

Operating principle of the present utility model is: when gate is positioned at limit inferior, impose vertically upward a external force as if the left side to gate this moment, then the left end of gate rises, under action of gravity, counterweight descends, owing to lie in the top that its other end of wire rope of gate top right-hand member also lies in same counterweight, so the time, what descend can synchronously promote the gate right-hand member by wire rope resetting, and realizes that the gate balance rises.In like manner, (impose an external force vertically downward this moment) when external force imposes on the gate right side or needs closed shutter, its result also is the same, so just can realize the gate balance lifting.

Compared with prior art, the utlity model has positive effects such as gate opening/closing is smooth and easy, compact conformation, cost of production reduction, long service life.

The specific embodiment

Embodiment

Preferred embodiment of the utility model is referring to shown in Figure 2.A kind of single counterweight formula balance gate is made up of the pulley 13,16 of pulley 12,14, wire rope 17 and the guiding movement thereof of gate 8, lead 18, counterweight 11, wire rope 15 and guiding movement thereof.Gate 8 can move up and down along the lead 18 of being located at its both sides.Counterweight 11 is located at gate 8 left sides.Wire rope 15 1 ends tie up to gate 8 top left side, and its other end lies in counterweight 11 tops after successively walking around pulley 14,12.Wire rope 17 1 ends tie up to gate 8 top right side, and its other end lies in counterweight 11 tops after successively walking around pulley 16,13.During adjustment, gate 8 is placed horizontal level, regulate two wire rope 15,17, its uniform tension in order is got final product, it is fastening good at last each end of wire rope 15,17 and corresponding system to be connect thing.

The utility model also comprises with steel cable and replaces two wire rope to reach identical effect: at first with wire rope rope in gate 8 top left side, its other end is walked around pulley 14,12 and is passed counterweight 11 top earrings and walk around pulley 13,16 again and lie in gate 8 top right side, then gate 8 is placed horizontal level, regulate two sections wire rope, make its uniform tension in order, will tighten up around the wire rope claim-reduction of counterweight 11 top earrings at last and get final product.

Above-mentioned two kinds of embodiments are assembly pulley height collocation form, can be the horizontal arrangement mode also with assembly pulley height configuration mode equivalent transformation, at this moment, only need the pulley of a duplex type groove of pulley 12,13 usefulness is replaced getting final product, pulley 14 also can adopt duplex type groove pulley.

Claims

1, a kind of single counterweight formula balance gate structure, comprise that gate, lead, wire rope, counterweight, pulley, gate can do upper and lower moving along the lead of its both sides, it is characterized in that: described two wire rope one ends lie in the left and right symmetry end in gate top respectively, and the other end of these two wire rope is walked around assembly pulley respectively and lain in a counterweight top.

2, single counterweight formula balance gate structure according to claim 1, it is characterized in that: described single counterweight is located at the left side or the right side of gate.
