Abstract
The utility model relates to a non-wound compensation chain for an elevator. The non-wound compensation chain comprises a plurality of groups of iron chains which are respectively formed by sequentially buckling a plurality of iron rings, wherein the groups of iron chains are sequentially arranged in a row; the uppermost iron rings of all groups of iron chains are connected into a whole, and the lowermost iron rings of all groups of iron chains are connected into a whole, so the groups of iron chains form a flat chain plate; the groups of iron chains are arranged in a noise-reducing jacket; sewing lines are arranged at two sides of the noise-reducing jacket in the vertical directions; the sewing line in the vertical direction is arranged at a vertical gap in the middle of the two adjacent iron chains; sewing threads are arranged in the middles of the iron rings which are parallel to the end face of the noise-reducing jacket in the groups of iron chains; and the noise-reducing jacket is made of canvas or glass fiber cloth. By the adoption of the technical scheme, the problem of twisting of the compensation chain is solved, the noise of the compensation chain is reduced, and abrasion to a noise-reducing material is reduced. The non-wound compensation chain for the elevator is wide in temperature application range and easy to automatically produce.
Description
Technical field
The utility model particularly relates to a kind of elevator and twines compensation chain with nothing about a kind of elevator counterweight compensation chain.
Background technique
In elevator components, the effect of compensation chain is that balance high rise elevator rope capacity changes the counterweight proportional imbalance that causes.Compensation chain follows the operation lifting of elevator to rise together and descend.Moving up and down of compensation chain can produce noise because the friction of iron chains self and collision are moved, and the counterweight main body of traditional compensation chain is iron chains for this reason, just can be applied on the elevator behind the installing damping device.
In the prior art, as shown in Figure 2, generally, iron chains 1 is interlocked successively by a plurality of iron hoops 2 and forms, as shown in Figure 1, central shaft by a plurality of rollers 3 connects to form a ring support 4, ring support 4 is connected on the ground of melt pit, compensation chain 7 passes through in the hole of ring support 4 centres, play the purpose that prevents that compensation chain 7 from twining, but in actual applications, as shown in Figure 3, the profile of chain 7 is a compensation chain 7 that is tending towards circle substantially by way of compensation, when compensation chain 7 one ends are fixed on the counterweight 5, the other end is fixed on the car 6, when compensation chain 7 freely sagging long the time, because the twisting stress of compensation chain 7 inside, the phenomenon of twining occurs easily, affect the security of operation of elevator, in order to solve the problem that occurs among Fig. 3, as shown in Figure 4, install compensation chain wheel apparatus 8 additional in the bottom of compensation chain 7, compensation chain 7 passes the center of compensation chain wheel apparatus 8, under the rectification of compensation chain wheel apparatus 8, the winding problem of compensation chain 7 temporarily is eased, but the problem of bringing is exactly the noise that compensation chain 7 collisions produce, as shown in Figure 5, and for the noise that reduces compensation chain 7, realize absorbing the noise that bump produces between iron hoop by the iron hoop that cotton cord 9 contacts is passed iron chains, the drawback of this method is that cotton cord 9 passes iron hoop back and forth, is difficult for automatic production, many employing manual operations, and shown in Figure 6, plastic cement 10 is wrapped in method on the compensation chain 7, easily automatic production, the noise-decreasing successful, but plastic cement 10 can not be operated in the low temperature environment.Plastic cement 10 sclerosis in the low temperature environment will breaking releasing after the bending several times.
The model utility content
In view of this, main purpose of the present utility model is to provide a kind of elevator to twine compensation chain with nothing, pass through the technical program, can effectively overcome all drawbacks of above-mentioned prior art scheme, solved compensation chain turn round around, compensation chain noise abatement and reduction have realized automatic production, thereby have remedied the deficiencies in the prior art the problem of noise abatement fret wear.
In order to achieve the above object, the technical solution of the utility model is achieved in that a kind of elevator twines compensation chain with nothing, include the iron chains that array is interlocked successively and formed by a plurality of iron hoops, described array iron chains is arranged in order in a row, the top iron hoop of described every group of iron chains is connected as one, the bottom iron hoop of described every group of iron chains is connected as one, thereby makes the array iron chains consist of the flat carrier bar.
Described array iron chains is arranged in the noise abatement sheath, and the Vertical direction in noise abatement sheath both sides is provided with the sewing line, is provided with the sewing line of Vertical direction at the vertical clearance gap place at two adjacent iron chains middle parts.
The iron hoop neutral position that parallels with noise abatement sheath end face in the described array iron chains is provided with sewing thread.
Described noise abatement sheath is made by canvas or glass fiber cloth.
Beneficial effect after the employing technique scheme is: a kind of elevator twines compensation chain with nothing, by the technical program, solved compensation chain and turned round around, compensation chain noise abatement and reduce problem to the noise abatement fret wear, and Applicable temperature is in extensive range, is easy to the automation processing.

Embodiment
Below in conjunction with accompanying drawing specific embodiment in the utility model is described in further detail.
As shown in Figure 7, the elevator that the utility model relates to twines compensation chain with nothing, include the iron chains 1 that array is interlocked successively and formed by a plurality of iron hoops 2, described array iron chains 1 is arranged in order in a row, the top iron hoop 2 of described every group of iron chains 1 is connected as one, the bottom iron hoop 2 of described every group of iron chains 1 is connected as one, thereby makes array iron chains 1 consist of the flat carrier bar.
Described array iron chains 1 is arranged in the noise abatement sheath 11, and the Vertical direction in noise abatement sheath 11 both sides is provided with sewing line 12, is provided with the sewing line 12 of Vertical direction at the vertical clearance gap place at two adjacent iron chains 1 middle parts.
Described noise abatement sheath 11 is made by canvas or glass fiber cloth.
The above only is better possible embodiments of the present utility model, is not to limit scope of the present utility model.
