Description
Technical Field
The utility model belongs to the technical field of elevator equipment, and particularly relates to an anti-breaking protection device for an elevator compensation chain.
Background
When the elevator runs, when the elevator car is positioned at the top floor, most of the steel wire rope is positioned at the counterweight side, and the weight of the steel wire rope is increased at the counterweight side; when the car is at the bottom floor, the steel wire ropes are mostly arranged at the car side, and the weight of the steel wire ropes is increased at the car side. Therefore, in order to ensure that the elevator has sufficient traction force or driving motor power, a compensating device for compensating the mass of the suspension wire ropes of the elevator is required to be arranged, and the compensating device can be in the form of a chain at a low speed, namely a compensating chain, which is a very critical part of the elevator. The current national elevator standard GB/T7588.1-2003 and the new national elevator standard GB/T7588.1-2020 to be implemented do not provide protection requirements for the breakage of the compensating chain. During the running process of the elevator, if the compensating chain is broken, the dragging force can be insufficient, but at the moment, if no detection means exists, the elevator has safety risks.
The apparatus in the comparison document CN211769592U has the following problems: the compensation chain protection structure and the guide structure are integrated, so that the application range is limited; the device is put the restriction many, and compensation chain running angle need be perpendicular and to heavy support body, otherwise arrange the difficulty.
The apparatus in the comparison document CN102976181A has the following problems: the structure is complex, the cost is high, the product is easy to damage after use, and the reuse rate is low; the bearing groove structure is easy to damage the compensating chain; the compensation chain is the moving part, has certain rocking condition of swaing during the operation, selects the half package compensation chain with hoop lock joint structure more during low-speed, and the surface is unsmooth, moves through the too much restriction compensation chain and easily appears scraping and touch, and damage appears in the light person, serious can cause bigger danger.
SUMMERY OF THE UTILITY MODEL
In order to solve the problems in the prior art, the utility model provides an anti-breaking protection device for an elevator compensation chain.
The utility model is realized by the following technical scheme: an anti-break protection device of an elevator compensation chain comprises a cover plate, a base, a spring and a switch; a switch fixing frame is arranged in the middle of the upper end of the base, and a switch is arranged on the switch fixing frame; the upper end of the base is also vertically provided with a plurality of screw rods which are circumferentially distributed on the outer side of the switch fixing frame; the lower end of the cover plate is provided with a kit corresponding to the screw rod, and the kit is movably sleeved outside the screw rod; a limiting piece in threaded connection with the top of the screw rod is arranged in the sleeve; a spring sleeved on the screw rod is also arranged between the sleeve piece and the base; the middle part of the lower end of the cover plate is also provided with a switch touch plate corresponding to the switch.
Furthermore, the switch and the switch fixing frame are fixed in a threaded manner through a waist-shaped hole, and the position of the switch can be adjusted up and down.
Further, the number of the screws is four.
The utility model has the beneficial effects that: the compensation chain breakage preventing structure only has a breakage preventing function and is not provided with guide, the universal type is stronger, and the size of the cover plate can be adjusted according to the actual situation so as to be suitable for different scenes; the structure is simple, the four corners support structure is adopted, and the stability is good; the device has an independent integral structure, can be fixed and directly placed, can be horizontally and horizontally placed or can be horizontally and vertically placed, and has strong applicability; low cost, simple structure and uneasy damage.
Drawings
FIG. 1 is a schematic diagram of the overall structure of the present invention;
FIG. 2 is a schematic diagram of an embodiment of the present invention.
In the figure, the main part number 1 and the cover plate are explained; 2. a switch touch panel; 3. a base; 4. a switch; 5. a spring; 6. a switch fixing frame; 7. a screw; 8. a kit; 9. a limiting member; 10. a compensation chain; 11. an elevator pit floor; 12. an elevator counterweight; 13. an elevator car.
In order to more clearly illustrate the technical solutions of the embodiments of the present invention, the drawings needed to be used in the embodiments will be briefly described below, and it is obvious that the drawings in the following description are only embodiments of the present invention, and it is obvious for those skilled in the art that other drawings can be obtained according to the drawings without creative efforts.
Detailed Description
As shown in fig. 1-2, a switch fixing frame 6 is arranged in the middle of the upper end of the base 3, a switch 4 is arranged on the switch fixing frame, the switch and the switch fixing frame are fixed in a waist-shaped hole in a threaded manner, and the position of the switch can be adjusted up and down; the upper end of the base is also vertically provided with a plurality of four screw rods 7 which are circumferentially distributed on the outer side of the switch fixing frame to form a four-corner supporting structure, so that the stability is good; the lower end of the cover plate 1 is provided with a sleeve 8 corresponding to the screw rod, and the sleeve is movably sleeved outside the screw rod; a limiting part 9 in threaded connection with the top of the screw rod is arranged in the sleeve, and the cover plate moves up and down between the limiting part and the base through the sleeve; a spring 5 sleeved on the screw rod is also arranged between the sleeve and the base, so that the cover plate moving downwards can rebound to the original position through four springs arranged between the sleeve and the base; the switch touch panel 2 corresponding to the switch is further arranged in the middle of the lower end of the cover plate, after the switch touch panel falls down and triggers the switch, the switch can cut off a safety loop of the elevator to stop the elevator from running, and the cover plate can be adjusted in size according to actual conditions to be suitable for different scenes.
The working principle of the utility model is as follows:
the device is placed below a compensation chain 10 between an elevator car 13 and an elevator counterweight 12 and is fixed with an elevator pit ground 11; when the compensating chain is broken, the falling compensating chain falls on a cover plate of the compensating chain anti-breaking device, the cover plate moves downwards at the same time, an electrical switch is triggered, a safety loop of the elevator is cut off after the switch acts, and the elevator stops running to prevent further danger;
the utility model utilizes the gravity of the broken compensation chain to press the cover plate and simultaneously drives the switch touch plate trigger switch to cut off the safety loop of the elevator, thereby solving the safety risk existing after the breakage of the compensation chain. The compensation chain breakage preventing structure only has a breakage preventing function and is not provided with guide, the universal type is stronger, and the size of the cover plate can be adjusted according to the actual situation so as to be suitable for different scenes; the device has an independent integral structure, can be fixed and directly placed, and can be horizontally placed or vertically placed; simultaneously this novel simple structure, safety and stability, extensive applicability, not fragile advantage have.
