Specific embodiment

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work Every other embodiment obtained, any modification, equivalent replacement, improvement and so on should be included in the utility model Within protection scope.

As shown in Figures 1 to 7, the mobile arresting stop of a kind of elevator, including mobile base 3, edge firm banking 1, center Firm banking 2, when elevator operates normally, the fixed hole in mobile base 3 is socketed in the fixation positioned at 1 upper surface of firm banking On stud 4, then tightened on fixed bolt with bolt；On edge firm banking 1, as shown in Figure 1 and Figure 5, center fixing seat 2 Carriage center is fixed on the projection centre position of pit by expansion bolt, and buffer 23 is installed on center base bracket 21 Top, firing pin type inspection switch pedestal 22 are fixed by bolts on center base bracket 21, and buffer 23 is normally transported in elevator As the protective device of elevator when row；Mobile base 3 is by buffer bar 34, mobile bracket 31, firing pin type moving switch 33 and hits Pin type switch bracket 32 forms, and buffer bar 34 is installed on mobile 31 top of bracket, and firing pin type moving switch 33 is opened by firing pin type It closes bracket 32 and is fixed on mobile 31 side of bracket.Edge fixing seat 1 is by edge base support 11 and firing pin type run switch pedestal 12 compositions, firing pin type run switch pedestal 12 are fixed by bolts on edge base support 1, and firing pin type moving switch 33 is accurate Be pressed on firing pin type run switch pedestal 12.

When inspection travel, the fixed bolt 4 of the welding on edge firm banking 1 is moved to center by mobile base 3 and is consolidated Determine on the fixed bolt 4 on pedestal 2 (to understand for convenience, edge firm banking 1, the stud of 2 upper surface of center firm banking are equal It is indicated using fixed bolt 4).Center fixing seat 2 is by center base bracket 21, buffer 23, firing pin type inspection switch pedestal 22 compositions, buffer 23 are installed on the top of center base bracket 21, during firing pin type inspection switch pedestal 22 is fixed by bolts in On heart base support 21, firing pin type moving switch 33 is accurately pressed on firing pin type inspection switch pedestal 22, on mobile bracket 31 Buffer groove 35 be socketed in the outside of buffer 23.

The specific steps of entire lift facility operation are as follows:

Step 1: after opening elevator door, pit is introduced into when maintenance staff overhaul pit, by mobile base 3 from side Edge firm banking 1 is disassembled and is moved out, and firing pin type moving switch 33 is detached from the firing pin type operation on edge firm banking 1 at this time Switch pedestal 12, the firing pin type run switch in Fig. 7 disconnect that (firing pin type run switch is by firing pin type moving switch 33 and firing pin type Run switch pedestal 12 matches composition), so as to cause elevator safety loop disconnection, elevator cannot be run；

It is fastened step 2: moving mobile base 3 on center firm banking 2 blending bolt, at this time firing pin type moving switch 33 are pressed onto the firing pin type inspection switch pedestal 22 on center firm banking 2, and the firing pin type inspection switch in Fig. 7 is closed (firing pin type Inspection switch is matched with firing pin type inspection switch pedestal 22 by firing pin type moving switch 33 and is constituted), lift loop is connected, only To carry out inspection travel, control switch when car top overhauling in Fig. 7 switch is elevator normal service, the design of mobile base is high Degree is greater than national standard, and the height of square can be accommodated when carriage is compressed on buffer completely；

Step 3: mobile base 3 is disassembled and is moved out from center firm banking 2, is hit at this time when maintenance is completed Firing pin type inspection switch pedestal 22 on 33 off center firm banking 2 of pin type moving switch, the firing pin type inspection switch in Fig. 7 It disconnects, so as to cause lift loop disconnection, elevator cannot be run；

It is fastened step 4: moving mobile base 3 on edge firm banking 1 blending bolt, at this time firing pin type moving switch 33 are pressed onto the firing pin type run switch pedestal 12 on edge firm banking 1, the firing pin type run switch closure in Fig. 7, elevator peace Full loop is connected, and can be operated normally.

In summary: the utility model proposes mobile arresting stop, mobile base fixed from edge in maintenance When pedestal is moved away, safety circuit is disconnected, and when mobile base is fixed to center firm banking, can just be overhauled Operation；After the completion of maintenance, mobile base is moved away from center firm banking, safety circuit disconnects, until mobile base is fixed to It can just be operated normally when edge firm banking.Overall structure is simple, using mechanical stop carriage, securely and reliably, leads to Electrical control maintenance and normal operating mode are crossed, it is easy to use, using meeting the needs of small pit installs ladder additional, reduce old small Area decreases the repair and maintenance security risk of small pit while installing cost additional.
