Abstract
The utility model discloses a mechanical height-limitation device of an elevator. A tooth-shaped steel plate with teeth at two sides is arranged at the highest position of an upright post which needs to be limited. A locking device is matched with the tooth-shaped steel plate; the locking device is arranged on a moving parts used for up-down movement of the elevator. The locking device consists of a shell, a wedge-shaped sliding block, an inclined guide bar and a compression spring; an intra-cavity of the shell is provided with two big end down symmetrical inclined planes; the inclined guide bar parallel with the inclined planes is arranged on the shell; the wedge-shaped sliding block is sleeved on the inclined guide bar; a gap exists between an inclined hole of the wedge-shaped sliding block and the inclined guide bar; the wedge-shaped sliding block can slide up and down on the inclined guide bar; the outer side of the wedge-shaped sliding block is of a big end down wedge shape and is matched with the inclined planes of the shell intra-cavity; the inner side of the wedge-shaped sliding block is provided with the teeth and is geared with the teeth on the tooth-shaped steel plate; the compression spring is arranged between the wedge-shaped sliding block and the shell bottom surface. By the adoption of the mechanical height-limitation device of the elevator, the height-limitation motion of the elevator is reliable without accidents.
Description
Affiliated technical field
The utility model relates to a kind of height limiter of elevator, is particularly useful for the height limiter of the elevator that building operation uses.
Background technology
The height limiter of the elevator that existing building operation is used is to utilize to hit the top limit switch, cuts off the electricity supply the operation of stop elevator, the operation height of restriction elevator.Its weak point is: the height limiter of this electromagnetic type, and because of exposing in atmosphere, many again dust, contact head is often malfunctioning, and the limit for height action of elevator is unreliable, often accidents caused.
The utility model content
The purpose of this utility model is the mechanical type height limiter that a kind of elevator is provided in order to overcome above-mentioned weak point, and the limit for height reliable in action of elevator can be not accidents caused.
The technical scheme that its technical matters that solves the utility model adopts is: the column of elevator fixes on the ground, at the highest position of limit for height that needs of column the tooth form steel plate that a two sides has tooth is installed.The lower end of tooth form steel plate is conical, and guiding insertion effect is arranged.What match with the tooth form steel plate is locking mechanism, and locking mechanism is installed on the movable part that elevator moves up and down.Locking mechanism is made up of shell, wedge slide block, oblique pilot bar, compression spring, the inner chamber of shell has two up-small and down-big symmetrical inclined-planes, the oblique pilot bar parallel with the inclined-plane arranged on shell, on oblique pilot bar, be with the wedge slide block, gapped between the inclined hole of wedge slide block and the oblique pilot bar, the wedge slide block can slide up and down at oblique pilot bar, and the outside of wedge slide block is up-small and down-big wedge, matches with the inclined-plane of shell inner cavity; The tooth that the inboard of wedge slide block has on tooth and the tooth form steel plate is meshed.Between wedge slide block and shell bottom surface, compression spring is housed.Its working process is such: when the working part of elevator arrived the limit for height position, working part was in overhead positions, and at this moment, the locking mechanism that is connected with working part inserts in the tooth form steel plate, and working part is locked on the column.
Effective effect of the present utility model is, uses the mechanical type height limiter of elevator of the present utility model, and the limit for height reliable in action of elevator can be not accidents caused.
Description of drawings
Figure is the structure cutaway view of the mechanical type height limiter of elevator of the present utility model.1-tooth form 1 steel plate among the figure, 2-compression spring, the oblique pilot bar of 3-, 4-wedge slide block, 5-shell, 6-tooth.
Specific implementation method
The column of elevator fixes on the ground, at the highest position of limit for height that needs of column the tooth form steel plate (1) that a two sides has tooth (6) is installed.The lower end of tooth form steel plate (1) is conical, and guiding insertion effect is arranged.What match with tooth form steel plate (1) is locking mechanism, and locking mechanism is installed on the movable part that elevator moves up and down.Locking mechanism is made up of shell (5), wedge slide block (4), oblique pilot bar (3), compression spring (2), the inner chamber of shell (5) has two up-small and down-big symmetrical inclined-planes, be fixed with the oblique pilot bar (3) parallel at shell (5) with the inclined-plane, on oblique pilot bar (3), be with wedge slide block (4), gapped between the inclined hole of wedge slide block (4) and the oblique pilot bar, wedge slide block (4) can slide up and down in oblique pilot bar (3), the outside of wedge slide block (4) is up-small and down-big wedge, matches with the inclined-plane of shell (5) inner chamber; The tooth that the inboard of wedge slide block (4) has on tooth (6) and the tooth form steel plate (1) is meshed.Between wedge slide block (4) and shell (5) bottom surface, compression spring (2) is housed.When the working part of elevator arrived the limit for height position, working part was in overhead positions, and at this moment, the locking mechanism that is connected with working part inserts in the tooth form steel plate, and working part is locked on the column.
Claims (2)
1, the mechanical type height limiter of elevator, it is characterized in that: the tooth form steel plate that a two sides has tooth is installed at the highest position of limit for height that needs at the elevator column, what match with the tooth form steel plate is locking mechanism, locking mechanism is installed on the movable part that elevator moves up and down, locking mechanism is by shell, the wedge slide block, oblique pilot bar, compression spring is formed, the inner chamber of shell has two up-small and down-big symmetrical inclined-planes, the oblique pilot bar parallel with the inclined-plane arranged on shell, on oblique pilot bar, be with the wedge slide block, gapped between the inclined hole of wedge slide block and the oblique pilot bar, the outside of wedge slide block is up-small and down-big wedge, match with the inclined-plane of shell inner cavity, the tooth that the inboard of wedge slide block has on tooth and the tooth form steel plate is meshed, and between wedge slide block and shell bottom surface compression spring is housed.
2, the mechanical type height limiter of elevator according to claim 1 is characterized in that: the lower end of tooth form steel plate is conical.
