Description

Novel durable counterweight door

Technical Field

The utility model belongs to the technical field of the overhead door, concretely relates to novel durable counter weight door.

Background

The existing lifting door mostly adopts spring torque balance weight, the torque of the spring acts on the shaft, a steel wire rope for suspending a door body acts on the same shaft through rope wheel reverse torque, balance is formed, a motor or manpower can rotate the shaft through smaller torque, so that the door can move up and down to form opening and closing, the problem of fatigue life exists in the use of the spring, the number of the springs is generally 2-6 ten thousand, the door which is frequently passed does not need to be replaced once a year, the cost is about 1/3 of the whole door, and the use cost is too high.

Disclosure of Invention

In order to overcome the above-mentioned technical problem that prior art field exists, the utility model aims to provide a novel durable counter weight door, very big reduction in the use potential safety hazard and the use cost that the torsional spring fracture brought.

The utility model provides a pair of novel durable counter weight door, including wire rope wheel, balancing weight line wheel, central balance axle, balancing weight, counter weight pipe, the promotion door body, the top at the wall hole of staying is fixed to central balance axle, the both ends of central balance axle are close to the position installation wire rope wheel of the wall hole of staying, and the position installation balancing weight line wheel in the both ends wire rope wheel outside of central balance axle, wire rope takes turns to and twines door body wire rope, the end of door body wire rope is fixed in the bottom of the promotion door body, the last winding balancing weight wire rope of balancing weight line wheel, balancing weight wire rope's end-to-end connection balancing weight, wire rope wheel and balancing weight line wheel are the line wheel of the same kind, the both ends wire rope of central balance axle takes turns to and twines door body wire rope's winding direction the same, the both ends balancing weight wire rope of central balance axle takes turns to The winding directions of the counterweight pipes are opposite, the counterweight pipes are fixed on the walls on two sides of the door opening, and the counterweight blocks are arranged in the counterweight pipes.

And support frames are respectively arranged at the two sides of the wire wheel of the balancing weight on the central balance shaft and the wire wheel of the steel wire rope.

The counterweight steel wire rope and the door body steel wire rope adopt anti-rotation 5mm steel wire ropes or 7mm steel wire ropes.

The weight of the balancing weight and the weight of the lifting door body are the same, and the weight of the balancing weight offsets the weight of the door body, so that balance is formed.

The counter weight pipe is the PVC material, and the outside adopts the pipe strap to fix on the wall, and the counter weight pipe is as orbit and protection to prevent that the balancing weight collision from rocking.

The middle part of the central balance shaft is provided with a middle support frame.

The width of the lifting door body is 2-10 meters, the height of the lifting door body is 2-7 meters, the lifting door body has enough tensile strength and fatigue strength, and the safe operation of the lifting door body is ensured.

The utility model provides a pair of novel durable counter weight door, its beneficial effect lies in, and the counter weight system is changed into by spring moment of torsion counter weight: through the gravity with the reverse winding balancing weight wire rope of door body wire rope and balancing weight, it takes turns to the reverse moment of torsion to act on, thereby form the balance, the motor uses very little power can promote the door body to open and close, also can switch to manually when even not having the electricity, it easily opens to push the door body with manpower, almost no cost of maintenance, be particularly suitable for using in comparatively frequent logical mouth, only need two years change wire rope once, normal maintenance at ordinary times can, very big reduction in use the potential safety hazard that the torsional spring fracture brought and the use cost that the torsional spring was changed and is brought.

Detailed Description

The present invention provides a novel durable counterweight door, which is described in detail below with reference to the accompanying drawings.

Examples

Referring to fig. 1, the novel durable counterweight door of this embodiment includes a wire rope wheel 1, a counterweight wire wheel 2, a central balance shaft 3, a counterweight 4, a counterweight pipe 5, and a lifting door body 6, where the central balance shaft 3 is fixed above a door opening left in a wall, the wire rope wheel 1 is installed at a position where two ends of the central balance shaft 3 are close to the door opening left in the wall, the counterweight wire wheel 2 is installed at a position outside the wire rope wheel 1 at two ends of the central balance shaft, a door wire rope 7 is wound on the wire rope wheel 1, the end of the door wire rope 7 is fixed at the bottom of the lifting door body 6, a counterweight wire rope 8 is wound on the counterweight wire wheel 2, the end of the counterweight wire rope 8 is connected with the counterweight 4, the wire rope wheel 1 and the counterweight wire wheel 2 are wire wheels of the same type, the winding directions of the door wire ropes wound on the, the winding direction of the counterweight steel wire ropes wound on the counterweight wire wheels at the two ends of the central balance shaft is opposite to the winding direction of the door body steel wire ropes, the counterweight pipe 5 is fixed on the walls at the two sides of the door opening, and the counterweight 4 is arranged in the counterweight pipe 5.
