Description
Technical field
The utility model relates to technical field of elevator equipment more particularly to a kind of screw type elevator carriage Anti-over-hoisting devices.
Background technique
Screw type elevator is as a kind of elevator to traditional structure, and when carriage movement, screw rod and backpack devices are logical
Cross screw pair relative motion, when screw type elevator break down when, be likely to result in Knapsack-rack promotes always simultaneously and upper beam assembly
It collides, to be damaged to apparatus assembly.
Summary of the invention
In order to solve deficiency in the prior art, it is anti-that the purpose of this utility model is to provide a kind of screw type elevator carriages
It rushes to summit device.
The technical scheme adopted by the utility model to solve the technical problem is as follows:
A kind of screw type elevator carriage Anti-over-hoisting device, including upper beam assembly, pedestal and the screw rod being arranged between,
Screw rod is equipped with Knapsack-rack, it is characterised in that:
The upper beam assembly lower part is additionally provided with the wirerope of a genesis analysis, passes through a upper limit plate in the middle part of wirerope and sets
It sets, and is equipped on wirerope in upper limit plate top and is connected thereto fixed lock, wirerope bottom end is connect with a lower limiting board,
Lower limiting board top is equipped with the limit switch of corresponding setting, and the upper limit plate is mounted on the Knapsack-rack, under described
Limit plate and limit switch are mounted on the base.
The beneficial effects of the utility model are: it is reasonable in design, it contacts to drive lower limit with upper limit plate by latching
Position plate touches limit switch, realizes the emergency braking of screw type elevator, improves the safety that screw type elevator uses.
Detailed description of the invention
The present invention will be further described with reference to the accompanying drawings and examples.
Fig. 1 is the structural schematic diagram of the utility model.
In figure: 1 upper beam assembly, 2 screw rods, 3 Knapsack-racks, 4 wirerope, 5 locks, 6 upper limit plates, 7 lower limiting boards, 8 limits
Switch, 9 pedestals.
Specific embodiment
The embodiments of the present invention is illustrated by particular specific embodiment below, those skilled in the art can be by this
Content disclosed by specification understands other advantages and effect of the utility model easily.
The present embodiment provides a kind of screw type elevator carriage Anti-over-hoisting devices, including upper beam assembly 1, pedestal as shown in Figure 1:
9 and the screw rod 2 that is arranged between, screw rod 2 be equipped with Knapsack-rack 3, screw rod 2 is by rotation for driving Knapsack-rack 3 to carry out
Lifting moving, in which:
1 lower part of upper beam assembly is additionally provided with the wirerope 4 of a genesis analysis, passes through a upper limit plate 6 in the middle part of wirerope 4
Setting, upper limit plate 6 are equipped with the hole passed through for wirerope 4, and are equipped with and are connected thereto in 6 top of upper limit plate on wirerope 4
Fixed lock 5, the hole that lock 5 is greater than upper limit plate 6 are arranged, and lock 5 is made to cannot pass through the setting of upper limit plate 6,4 bottom of wirerope
End is connect with the movable end of a lower limiting board 7, and 7 other end of lower limiting board is connected and fixed with pedestal 9, and 7 top of lower limiting board is equipped with
The limit switch 8 of corresponding setting, the dog point of limit switch 8 are located at its underpart and move up progress by lower limiting board 7
It touches, 8 side of limit switch is fixed on the pedestal 9 by mounting plate, and the upper limit plate 6 is weldingly fixed on described
On Knapsack-rack 3, and it is mobile with 3 synchronization lifting of Knapsack-rack.
A kind of working principle of screw type elevator carriage Anti-over-hoisting device are as follows: when continuing uplink after lift car leveling, knapsack
Upper limit plate 6 on frame 3 can encounter lock 5, and limit wirerope 4 will pull lower limiting board 7 to touch limit switch 8, limit
Switch 8, which issues signal, makes the driving motor of screw rod 2 stop working, and carriage runs out of steam and do not reoperate, and plays the work of protection passenger
With.
The foregoing is merely the preferred embodiments of the utility model, as long as realizing the utility model with essentially identical means
Purpose technical solution, belong within the protection scope of the utility model.
