Description

A kind of shock absorber of elevator gantry crane

Technical field

The utility model relates to a kind of elevator door-motor device, and more particularly, it relates to a kind of shock absorber of elevator gantry crane.

Background technology

In the door opening/closing apparatus of cage type elevator, gate is connected with Timing Belt by gantry crane, Timing Belt is driven by the driving system of motor, thus drive gate motion to realize unlatching or the closedown of motor gate, in the prior art, one end of gantry crane is fixedly connected with gate, the other end is fixed on Timing Belt by connecting element, when gate is closed, motor shuts down, Timing Belt shuts down, gate moves continuing under the effect at force of inertia of moment of Timing Belt stop motion, inevitable drive gantry crane moves together, although the distance of motion is very short, but the force of inertia that gate has pulls Timing Belt by the connecting element transferring to gantry crane, because Timing Belt is fixedly connected with connecting element, the junction of connecting element and Timing Belt will be impacted, equally, when gate is opened, Timing Belt moves and gantry crane geo-stationary, the junction of connecting element and Timing Belt also will be impacted, if things go on like this, the relative position of the two will be moved, gate is caused normally to close, also huge wearing and tearing can be produced to Timing Belt, therefore, need between gantry crane and Timing Belt, arrange the fixed connecting piece that has pooling feature.

Utility model content

For the problem in practice, the utility model proposes a kind of shock absorber of elevator gantry crane, by arranging the attaching parts with pooling feature at gantry crane and Timing Belt junction, when substantially reducing elevator switch door, gantry crane is to the impulsive force of Timing Belt, and concrete scheme is as follows:

A kind of shock absorber of elevator gantry crane, comprise top panel and lower faceplate, described top panel and lower faceplate are by multiple bolt bolt tightly and accompany Timing Belt therebetween, described lower faceplate is connected with the gantry crane of elevator cage door by pipe link, cavity is axially arranged with along it in described pipe link, the sidewall of described cavity is provided with groove, one end of described gantry crane to stretch in cavity through described groove and has been wholely set fixture block, and described fixture block can be provided with elastic component along the axial motion of cavity between the left and right sides wall of two ends and cavity.

Pass through technique scheme, when elevator cage door is opened or close, gantry crane continues to be moved along original sense of motion relative to Timing Belt under the effect of inertia, the fixture block that is positioned at cavity inside is driven to be moved along the axis of cavity, extruding elastic component, instantaneous impact is converted into elastic potential energy by elastic component generation deformation, also just alleviates the impulsive force of gantry crane to Timing Belt.

Further, described elastic component is spring or elastic gel.

Further, the part that described top panel, lower faceplate contact with Timing Belt is provided with rubber pad.

By above-mentioned setting, when top panel and lower faceplate clamp Timing Belt, top panel and the friction force between lower faceplate and Timing Belt can be increased, prevent from being subjected to displacement between pipe link and Timing Belt.

Compared with prior art, the utility model, by arranging elastic component in pipe link, has cushioned the impulsive force from gantry crane, prevents the upper and lower panel and the Timing Belt generation relative displacement that clamp Timing Belt, it also avoid Timing Belt and be worn.

Detailed description of the invention

Be described further with reference to Fig. 1-3 pairs of the utility model embodiments.

A kind of shock absorber of elevator gantry crane 5, comprise top panel 1 and lower faceplate 2, top panel 1 and lower faceplate 2 are by multiple bolt 3 bolt tightly and accompany Timing Belt 4 therebetween, lower faceplate 2 is connected with the gantry crane 5 of elevator cage door 11 by pipe link 12, cavity 6 is axially arranged with along it in pipe link 12, the sidewall of cavity 6 is provided with groove 7, one end of gantry crane 5 to be stretched in cavity 6 through groove 7 and has been wholely set fixture block 8, fixture block 8 can be provided with elastic component 9 along the axial motion of cavity 6 between the left and right sides wall of two ends and cavity 6, simply, elastic component 9 can select spring or elastic gel, play the object of protecting against shock.

When elevator cage door 11 is opened or is closed, gantry crane 5 continues to be moved along original sense of motion relative to Timing Belt 4 under the effect of inertia, the fixture block 8 that is positioned at cavity inside is driven to be moved along the axis of cavity, extruding elastic component 9, there is deformation and instantaneous impact be converted into elastic potential energy in elastic component 9, also just alleviates the impulsive force of gantry crane 5 pairs of Timing Belts 4.

When top panel 1 clamps Timing Belt 4 with lower faceplate 2, in order to increase top panel 1 and the friction force between lower faceplate 2 and Timing Belt 4, prevent from being subjected to displacement between pipe link 12 and Timing Belt 4, the part that top panel 1, lower faceplate 2 contact with Timing Belt 4 is provided with rubber pad 10.

Below be only preferred implementation of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, all technical schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
