Abstract

The utility model discloses a foldable kickboard of a lift car, which is characterized in that the kickboard comprises a fixed kickboard and a movable kickboard, wherein a limit device is arranged between the fixed kickboard and the movable kickboard, and a resetting device is installed between the fixed kickboard and the movable kickboard; and a positioning and locking device is arranged on the fixed kickboard, and two sides of the kickboard is provided with guiding devices. In the utility model, a simple mechanical structure is adopted, and the original fixed kickboard with the height incapable of being changed is changed into the foldable kickboard which can be applied to lifts driven by all modes, not only can be applied to the lifts of newly built buildings, but also can adapt to the use of the constructed lifts in the reconstruction of old buildings, and has more obvious superiority for the use in shallow pit lifts. According to the different depth of pits, two-layer foldable kickboards, three-layer kickboards or four-layer kickboards can be manufactured, and the foldable kickboard can be applied to center opening doors, side opening doors, midsplit two folding doors, center three folding doors and other lift cars with the door opening width of lift from 600-3200.

Description

A kind of folding lift car toeguard

Technical field the utility model relates to a kind of lift car toeguard that can fold, and this kind lift car toeguard can be applied in the elevator of normal use, also can use in the elevator that old building transforming installs additional, is specially adapted in the elevator of shallow melt pit.

Background technology is in the elevator toeguard that tradition is used, and the toeguard height all is greater than 750mm.New building just all can be considered elevator installation needs in design, and the elevator hoistways melt pit is reserved enough degree of depth, to satisfy the needs that elevator operation needs and toeguard are installed.And the elevator that installs additional in the old building transforming does not often possess darker melt pit, uses if elevator will be installed, and often just needs to have melt pit now and digs deeply, or bottom elevator doorway is raised, to satisfy operating needs.

Summary of the invention is at above-mentioned reality, the utility model provides a kind of lift car toeguard that can fold, this kind elevator toeguard can apply in the elevator that drives by any way, and can solve above-mentioned fully because the elevator that the toeguard height problem causes is installed a difficult problem.

The purpose of this utility model is achieved in that

A kind of folding lift car toeguard, it is characterized in that: described toeguard comprises fixedly backplate and moving apron, fixedly be provided with inhibiting device between backplate and the moving apron, fixedly between backplate and the moving apron reset attachment is being installed, positioning and locking device is arranged on fixedly on the backplate, and the both sides of described toeguard are provided with guide piece.

The quantity of described moving apron is 1 to 3, is provided with inhibiting device between two adjacent moving aprons.In theory, not restriction of quantity to moving apron, but consider the requirement that elevator running is used, quantity as moving apron is too many, and then the height of moving apron will require to do very for a short time, increases many inhibiting device and shock absorber simultaneously, make the complex structure of toeguard also increase manufacturing cost simultaneously, therefore, from practicality in principle, the quantity of 1 to 3 moving apron is comparatively suitable.

The bottom position of described moving apron is provided with shock absorber.The purpose that shock absorber is installed is fricative vibrations and a consequent bigger noise between plate and the plate when preventing that moving apron is flexible, and is simple and the efficient buffer device is at the bottom position of moving apron rubber pad to be installed.

The bottom of described toeguard is provided with the terminal suspending device.So-called installing terminal shock absorber is set in the bottom of toeguard is in order to prevent that elevator from moving when out of control, toeguard falls the bump pit suddenly and damages toeguard, usually also adopt rubber pad as the terminal suspending device, but the thickness of terminal suspending device is bigger than the thickness of above-mentioned shock absorber.

Folding lift car toeguard of the present utility model adopts simple physical construction, the fixedly toeguard that highly can not change is originally changed into foldable toeguard, can apply in the elevator that drives in all modes, promptly can be applied in the elevator of new building, more can adapt in the elevator of building in the old building transforming and use, in shallow pit elevator, use more can highlight its preceence.According to the pit depth difference, can make two layers of folding, three layers of folding or four layers of folding toeguard, be applicable to the elevator door opening width from the center opening door of 600-3200, side opening door, minute two folding door, on the lift car of three folding doors etc.

Description of drawings Fig. 1 is the utility model structural representation;

Fig. 2 is the left view of Fig. 1;

Fig. 3 is the birds-eye view of Fig. 1.

The specific embodiment is further described the specific embodiment of the present utility model below in conjunction with drawings and Examples:

Fig. 1 is the utility model structural representation, and Fig. 2 and Fig. 3 are respectively left view and the birds-eye vieies of Fig. 1.As Fig. 1, Fig. 2, shown in Figure 3, toeguard comprises fixedly backplate 1 and moving apron 2, toeguard has three layers of moving apron 2 in the present embodiment, fixedly be equipped with inhibiting device 4 between backplate 1 and the moving apron 2 and between two adjacent moving aprons 2, inhibiting device 4 is used to prevent moving apron 2 over travels.Between the upper position of fixing backplate 1 and moving apron 2, reset attachment 7 is installed, reset attachment 7 adopts gas spring, after its power effect outside disappears, utilize gas spring inner high voltage gas to automatically reset, positioning and locking device 8 is devices of a similar latch hook, be arranged on fixedly on the backplate 1, the both sides of described toeguard are provided with guide piece 3, guide piece 3 adopts metallic material to make, its cross section adopts the dovetail structure to do guiding, the bottom position of moving apron 2 is provided with the rubber pad 5 as shock absorber, terminal suspending device 6 is arranged on the bottom of toeguard, and be fixed on fixedly on the backplate 1, also make with rubber pad, its thickness is bigger than the thickness of rubber pad 5.

When normal the use, all moving aprons 2 all are folded state, and all under the effect of positioning and locking device 8, firm being installed in fixedly on the backplate 1, and electric affirmation elevator is a safe condition at this moment, elevator can normally use, and can transport the passenger.When elevator is in inspecting state, or elevator is when having fault to need inspection travel, elevator safety loop is cut off, elevator can not move, after the maintainer opens elevator door, the private key (triangular key) that employing meets elevator safety unclamps positioning and locking device 8, and this moment, the gas spring in the reset attachment 7 can flick under the effect of air pressure, guarantees that each moving apron 2 all opens by inhibiting device 4, rubber pad 5, terminal suspending device 6 in the stroke range of guide piece 3.Elevator reparing under external force, resets to normal working with above device after finishing.
