Abstract
An electric elevator system is composed of a vertical tunnel, a cage moving up and down in the vertical tunnel, a cunterweight moving reverse to said cage, the guide tracks for said cage and counterweight, a steel cable, and a counterweight fixer for preventing the movement of cage during maintenance.
Description
Technical field
The present invention relates to a kind of lift appliance, especially relate to a kind of elevator that the set machine in hoist trunk below is maintained of being suitable for.
Background technology
When being arranged on machines such as winch below the hoist trunk and maintaining, fall in order to prevent lift car, generally all to take the measure that prevents that lift car from moving.As the means that prevent that lift car from moving, a kind of following technical scheme had been proposed in the past, that is, in the both sides of shock absorber supporting is set uprightly and uses anchor clamps, and place this supporting with (for example referring to Patent Document 1) on the anchor clamps balance block.In addition, also have a kind of disclosed method to be, the partial balancing piece is disassembled, make the weight of lift car overweight the weight of balance block, utilize anchor clamps to support then, be moved upward (for example referring to Patent Document 2) to prevent balance block.Moreover, other has a kind of disclosed method to be, in order to stop lift car to move fully, blocking device is set above lift car, when lift car is moved to the top, operate this blocking device by the operating personnel, (for example refer to Patent Document 3) thereby lift car is fixed on the fixed mechanism that is arranged on the guide rail.
Patent documentation 1: Japanese patent laid-open 11-124285 communique (paragraph numbering 0025,0026, Fig. 1)
Patent documentation 2: the Japanese Patent spy opens 2001-192190 communique (paragraph numbering 0032, Figure 11)
Patent documentation 3: the Japanese Patent spy opens 2000-203774 communique (paragraph numbering 0042,0043, Fig. 3, Fig. 4)
In above-mentioned disclosed method, about balance block being placed supporting with the method on the anchor clamps, owing to just simply above-mentioned balance block is positioned over supporting with on the anchor clamps, so when existing winch and being driven for some reason, can cause the problem of lift car whereabouts.And in preventing the method that balance block is moved upward, not only need the partial balancing piece pulled down and reinstall and increase onerous toil, and, still exist just in case winch causes lift car to fall because of some reason is driven problem.As for the method that blocking device is set above lift car, then exist a very big problem, promptly behind this blocking device of operation, operating personal can't get off from lift car, therefore, except the operating personnel of operation in hoist trunk, also need to be equipped with the operating personal of this blocking device of specialized operations.
Summary of the invention
The object of the present invention is to provide a kind of lift appliance, this lift appliance can not need to increase under operating personnel's the situation, prevents moving of lift car effectively.
In order to realize above purpose, lift appliance of the present invention have hoist trunk, lifting in this hoist trunk lift car, with this lift car be the balance block of opposite sense lifting, above-mentioned lift car and balance block guide rail, suspention above-mentioned lift car and balance block main hoist cable and be arranged in the hoist trunk below machine, it is characterized in that, be provided with anchor fitting, when the machine below being arranged in the above-mentioned hoist trunk is maintained, above-mentioned balance block is fixed in the hoist trunk by this anchor fitting.
According to said structure, because balance block is fixed in the hoist trunk, so even contingency such as winch are driven, not only therefore lift car can not move, and balance block also can be therefore mobile, therefore can carry out safe operation.In addition,, this fixed operation can be carried out in pit, therefore other operating personnels need be do not sent in addition for fixed operation so carry out the operating personnel of machine maintenance because the fixed operation of balance block is carried out.
Description of drawings

The specific embodiment
Followingly describe with reference to the embodiment of accompanying drawing to lift appliance of the present invention.
Fig. 1 is the lateral plan of lift appliance overview of expression one embodiment of the invention, the lateral plan of state when Fig. 2 is fixed on the guide rail for the expression balance block, and Fig. 3 is the birds-eye view of the part shown in Figure 2 seen from upside.
In Fig. 1, the 1st, lifting in hoist trunk 7, be used to carry people and goods's lift car, the 2nd, the weight of above-mentioned lift car 1 is compensated, be the balance block of opposite sense lifting with above-mentioned lift car 1, this balance block 2 is made of the clump weight 2a that can install and remove, the balance block framework 2b that supports this clump weight 2a and hanging wheel 2c.The 3rd, suspend the main hoist cable of above-mentioned lift car 1 and above-mentioned balance block in midair, the 4th, drive lift cars and balance block so that the winch of its lifting by above-mentioned main hoist cable 3, this winch is fixed in the pit 7a of hoist trunk 7 bottoms.The 5th, be used for vertically guiding the lift car guide rail of above-mentioned lift car 1, the 6th, be used for vertically guiding the balance block guide rail of above-mentioned balance block 2, the 8th, the balance block shock absorber, 9 are arranged on the control setup of hoist trunk 7 bottoms, the 10th, when machines such as above-mentioned winch 4 of maintenance or above-mentioned control setup 9, constitute the bolt of rear end plate that is installed in the anchor fitting on the above-mentioned balance block framework 2b, the 11st, be fixed on the support unit on the above-mentioned balance block usefulness guide rail 6, this support unit 11 is configured to the U font, to avoid when the normal operation, promptly not when maintenance, lifting to above-mentioned balance block 2 produces obstacle, bottom 11a is fixed on balance block with on the guide rail 6 by bolt 12, and it is one overlapping with the sidepiece of above-mentioned balance block 2 at interval that two sidepiece 11b and 11c are configured to separate.
Below, the maintenance that just is arranged at the machine of hoist trunk below describes in proper order.Control above-mentioned control setup 9 to drive above-mentioned winch 4, make above-mentioned lift car 1 and 2 liftings of above-mentioned balance block by above-mentioned main rope 3, and make lift car 1 be positioned at the superiors, balance block 2 is positioned near the orlop.Afterwards, operating personnel 13 enters pit 7a, bolt of rear end plate 10 is inserted balance block framework 2b and sidepiece 11b and is fixed from the sidepiece 11c of support unit 11.Under this stationary state, carry out operation, then, after the end of job in pit 7a, unload bolt of rear end plate 10.
As mentioned above, during operation in carrying out pit, because balance block 2 has been fixed, so even winch 4 is just in case be driven, therefore the lift car 1 and the balance block 2 that are supported by main hoist cable 3 also can not move.Therefore, operating personnel 13 can carry out operation securely.In addition, because the operating personnel 13 who enters in the pit 7a can carry out fixed operation, therefore do not need to send in addition the operating personnel.
And in the above-described embodiments, support unit 11 is arranged on balance block with on the guide rail 6, and adopts bolt of rear end plate 10 to fix, but also can be with the support unit predetermined fixed on the sidewall of hoist trunk 7, then stable equilibrium piece 2 thereon.In addition, also can on balance block 6, offer through hole in advance, bolt of rear end plate be inserted in this through hole fix.Moreover, in the embodiment explanation, used bolt of rear end plate 10, fix but also can replace bolt of rear end plate with pin.
(invention effect)
Can realize with inferior significant invention effect according to the present invention, that is, because balance block is fixed in the hoist trunk, so even contingency such as winch are driven, not only therefore lift car can not move, and balance block also can be therefore mobile, therefore can carry out safe operation.In addition,, this fixed operation can be carried out in pit, therefore other operating personnels need be do not sent in addition for fixed operation so carry out the operating personnel of machine maintenance because the fixed operation of balance block is carried out.
