Detailed description of the invention
Below in conjunction with accompanying drawing, embodiments of the invention being described in detail, the multitude of different ways that requirement limits and covers but the present invention can have the right is implemented.
Embodiments of the invention are described in detail below in conjunction with accompanying drawing.
Fig. 1 illustrates the schematic diagram of counterweight mechanical stopping device of the present invention when elevator is properly functioning, and Fig. 2 illustrates the schematic diagram of counterweight mechanical stopping device of the present invention when overhauling elevator runs, and Fig. 3 illustrates the schematic diagram of counterweight mechanical stopping device of the present invention.As shown in Figure 1, Figure 2 and Figure 3, the invention provides a kind of elevator counterweight mechanical stopping device, this mechanical stopping device includes a support component 1, stops assembly 2, cushion rubber component 3 and keep assembly 5, fixing base plate 101 below described support component 1 and ground adopt setscrew to fix (shown in Fig. 4), and support component 1 side and counter weight guide track utilize guide rail clamp to fix.The one end stoping assembly 2 and prop up support component 1 adopts the axle of flexible rotating to fix.Cushion rubber component 3 is flexibly connected with the prevention beam 201 stoping assembly 2, keeps assembly 5 to be fixed on prevention beam 201.
As it is shown in figure 5, described prevention assembly 5 includes the two prevention beams 201 being arranged in parallel, two stop beam 201 axle 202 to connect.Described prevention beam 201 is provided with electric switch A40.
As shown in Figure 6, described cushion rubber component 3 includes yielding rubber 301, base plate 302 and pin P303, yielding rubber 301 is affixed with base plate 302, base plate 302 is connected by pin P303 with the prevention beam 201 stoping assembly 2, cushion rubber component 3 rotates around pin P303, is placed horizontally on prevention beam 201 and locks with latch 7.When cushion rubber component 3 horizontal positioned, touching electric switch A401 action, locking state signal is sent to control centre by electrical safety circuit by electric switch A401.
As it is shown in fig. 7, described maintenance assembly 5 includes baffle plate 501, pin Q502 and latch M503, baffle plate 501 rotates around pin Q502, fixes with latch M503 after being rotated in place.Baffle plate 501 is stuck in counter weight guide track and stops between beam 201, makes prevention beam 201 be in vertical state all the time.The electric switch B402 being fixed on supporting mechanism 1 is prevented from beam 201 and touches and keep vertical state, and this vertical state is verified by electric switch B402, and is sent to control centre.
When elevator is properly functioning, counterweight mechanical stopping device of the present invention is in vertical state, and arranges the reliability keeping assembly 5 to ensure the prevention vertical state of beam 201.When elevator is in inspecting state, first want manual operation that elevator counterweight mechanical stopping device of the present invention is put in level, namely assembly 2 is stoped to rotate to level around a support component 1, stoping the other end stay bolt of assembly 2 and a support component 1 for wing nut and opposite side to be fixed, now cushion rubber component 3 is locked with latch N7 after being placed horizontally on prevention beam 201.When cushion rubber component 3 horizontal positioned, the electric switch A401 being fixed on prevention beam 201 can be touched, and this locking state is verified by electric switch A401.When counterweight runs downwards and needs to ensure pit overhaul space, cushion rubber component 3 plays prevention cushioning effect.Elevator counterweight mechanical stopping device duty change procedure of the present invention all there are reliable electric switch A401, B402 to be verified.
Elevator counterweight mechanical stopping device of the present invention is prevented counterweight and is run downwards, and now traction disappears thus car stops running up, it is ensured that overhead.By as it is shown in figure 1, counterweight mechanical stopping device is fixed on ground and counter weight guide track in advance.Elevator stops assembly 2 to be in vertical state when properly functioning, by keeping assembly 5 to be stablized at reliable behavior, by electric switch B402, this state is verified.When elevator needs cage top overhauling to run, elevator operation personnel need to enter pit and counterweight mechanical stopping device are got to inspection travel state, namely stop assembly 2 to should be at level.First the emergency stop switch counterweight mechanical stopping device pressing elevator pit standard configuration when entering pit is operated.After entrance pit completes jerk operation, maintenance assembly 5 is opened by elevator operation personnel, put down and stop a support component 1 for beam 201 stay bolt 6 and opposite side to be fixed, then cushion rubber component 3 it is horizontally placed on prevention beam 201 and locks with latch 7, by electric switch A401, this state being verified.Last elevator operation personnel can enter sedan-chair jacking row overhauling elevator and run operation.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.All within the spirit and principles in the present invention, any amendment of making, equivalent replacement, improvement etc., should be included within protection scope of the present invention.
