On screw rod.When lever arm 44 is in folding state, as shown in Fig. 2, the height that roller devices 4 are higher by 1 surface of upper beam is little
It is higher by the height on 1 surface of upper beam in hanging beam 5, is interfered to avoid roller devices 4 and the remaining part in hoistway.
As shown in Figure 10, caging bolt 49,44 phase of lever arm of caging bolt 49 and folding state are additionally provided on substrate 41
To cooperation.The limit swing position of lever arm 44 is limited by caging bolt 49.
As shown in figure 9, locking mechanism includes：Mounting hole, activity on lever arm 44 are plugged in mounting hole and determine
Position pin 46 is located therein on one block of side plate 43 and drives positioning with 46 matched pin hole 43a of positioning pin and in mounting hole
Pin 46 enters the compression spring 48 of pin hole 43a.
Positioning pin 46 is equipped with the limited step 46a of annular, and compression spring 48 is set on positioning pin 46, the both ends point of compression spring 48
Not against lever arm 44 and limited step 46a.The position that pin hole 43a is arranged on side plate 43 is thinned, to give limited step 46a work
Dynamic space.
Under the promotion of compression spring 48, positioning pin 46 stretches into pin hole 43a, and limits positioning pin 46 by limited step 46a
The depth for stretching into pin hole 43a, when needing to unlock, overcomes the elastic force of compression spring 48, and positioning pin 46 is exited pin hole 43a.
The installation process of Elevator weight sensor provided by the utility model is as follows：
(1) counterweight frame is taken in 11 mouthfuls of spellings of hall door, counterweight frame is in the assembled state of horizontal as shown in Figure 5, Figure 6, idler wheel
Lever arm 44 in device 4 is in unfolded state as shown in Figure 3, Figure 4, as shown in Figure 11, Figure 12, in 1 He of counterweight frame upper beam
Wooden unit 10 is placed on 4 side of roller devices at underbeam 2, prevents counterweight frame from moving, each pair of 6 installation unit of pouring weight in counterweight frame
Interior placement is compressed to pouring weight 6, and by pressing plate.
(2) wooden unit 10 to be removed, counterweight frame is lifted using boom hoisting, counterweight frame is moved by roller devices 4 on floor,
Until the roller devices 4 on upper beam 1 leave ground, the roller devices 4 on underbeam 2 continue to move to, and as shown in figure 13, counterweight frame is worn
Cross hall door 11.
(3) as shown in figure 14, the positioning pin 46 in locking mechanism is exited pin hole by Elevator weight sensor completely into after in hoistway
In 43a, stirring lever arm 44 makes lever arm 44 be in folding state as shown in Figure 1 and Figure 2, and Elevator weight sensor installs.
