Abstract
The invention belongs to the technical field of tools for metro segments, and particularly relates to a locking mechanism of a lifting appliance for metro segments. The locking mechanism of the lifting appliance for the metro segments comprises a moving arm and a locking device. The locking device comprises a locking arm and an adjusting nut. A stop block is arranged on the locking arm, and the locking arm is connected with the adjusting nut through an adjusting screw rod. The moving arm comprises a connecting plate, a locking plate and a hooking head. The connecting plate and the locking plate are of an integrated bent structure, the locking plate and the hooking head are of an integrated bent structure, and the locking plate is provided with a locking opening. When the locking arm moves with a pin shaft as the center, the stop block on the locking arm can abut against the locking opening in the locking plate. The locking mechanism has the beneficial effects that the locking mechanism can change along with changing of the thicknesses of products, also can be used for ultra-thick segments, and cannot break the products by clamping when the thicknesses of the segments are not enough or gaps are too large due to abrasion.
Description
Technical field
The invention belongs to subway segment apparatus technical field, particularly relate to a kind of catch gear of subway segment suspender.
Background technology
Subway segment suspender generally lifts the position of locking hole, take fixed type locking arm, fixed type locking arm size just secures when making, due to fabrication error, section of jurisdiction does not put in place to the removing surface of section of jurisdiction when producing, excessive cleaning all can cause section of jurisdiction thickness to have 3-5mm change, if it is too little that fixed type locking arm gap is stayed, section of jurisdiction super thick, fixture will normally use, if too large (or because wearing clearance becomes large) that fixed type locking arm gap is stayed can make movable arm again, the gap of fixed arm also becomes large thereupon, product will be clipped broken, even can cause the accident that section of jurisdiction is fallen, in actual production, the breakage rate of product reaches 20%, this situation not only increases the labour intensity of workman, too increase cost of repair simultaneously, the presentation quality of section of jurisdiction is also had a great impact.
Summary of the invention
The object of the invention is to solve above-described technical matters, there is provided one can change with product thickness change in size, run into super thick section of jurisdiction also can use, not enough or owing to product also can not be caused to be pressed from both sides the catch gear of bad subway segment suspender when wearing and tearing cause gap too large, its technical scheme is as follows at section of jurisdiction thickness:
The catch gear of subway segment suspender, it is characterized in that, the catch gear of described subway segment suspender comprises movable arm and latching device, described latching device locking arm and setting nut, locking arm is provided with block, is connected by adjusting screw(rod) between locking arm and setting nut; Described movable arm comprises connecting plate, latch and eave tile, and described connecting plate and latch, latch and eave tile are bending integrative-structure, described latch are provided with fore shaft; When described locking arm moves centered by bearing pin, the block on locking arm can withstand mutually with the fore shaft on latch.
Optimal way is, described latch and the medial surface of eave tile are provided with movable arm anticollison block.
The catch gear of subway segment suspender provided by the invention, when in use, general activity arm is hingedly arranged on fixed arm, arranges between movable arm and fixed arm in chevron pointing.Movable arm is then can realize clamping product by the mode of activity.Thus by being used for realizing clamping the object of product while movable arm and fixed arm.And latching device plays and can change with product thickness change in size, run into the effect that super thick section of jurisdiction also can use, how gauge regardless of section of jurisdiction changes, as long as can use in the setting range of adjusting screw(rod) (the adjustment length of general adjusting screw(rod) is at 15mm).Improved like this fixture is in routine use, and product is well protected, and decreases service expenditure, improves the presentation quality of product.
The present invention is further provided with movable arm anticollison block, fixture can being made when clamping product to play the effect of mitigation, also can play the effect of shield jig while preventing damage of product.
The invention has the beneficial effects as follows: provide one can change with product thickness change in size, running into super thick section of jurisdiction also can use, not enough or bad owing to also product can not be caused to be pressed from both sides when wearing and tearing cause gap too large at section of jurisdiction thickness.

Detailed description of the invention
Embodiment is illustrated below in conjunction with Fig. 1 to Fig. 3:
As shown in Figure 1 to Figure 3, subway segment herringbone suspender, described subway segment herringbone suspender comprises fixed arm 1 and movable arm 2, and described fixed arm 1 and movable arm 2 are arranged in chevron pointing; The side lower part of described fixed arm 1 is provided with bracing frame 3, one end of described fixed arm 1 is connected with suspension ring 4, the other end of fixed arm 1 is movably hinged by bearing pin 5 and is connected with latching device 6, described latching device 6 comprises locking arm 61 and setting nut 62, locking arm 61 is provided with block 63, is connected by adjusting screw(rod) 64 between locking arm 61 and setting nut 62; Described fixed arm 1 is articulated with movable arm 2, and movable arm 2 comprises connecting plate 21, latch 22 and eave tile 23, and described connecting plate 21 and latch 22, latch 22 and eave tile 23 are bending integrative-structure, described latch 22 are provided with fore shaft 24; When described locking arm 61 moves centered by bearing pin 5, the block 63 on locking arm 61 can withstand mutually with the fore shaft 24 on latch 22.
Optimal way is, the bottom of described bracing frame 3 is provided with and supports anticollison block 7.
Optimal way is, described latch 22 and the medial surface of eave tile 23 are provided with movable arm anticollison block 8.
Optimal way is, described fixed arm 1 is provided with fixing anticollison block 9.
When its work, fall fixture, the fixed arm of fixture and movable arm is allowed to be clipped in product both sides, when bracing frame withstands product end, fixture just stops declining, the fixing anticollison block of fixed arm is allowed to against the outside of product, at this moment centered by pivot pin, lift locking arm, movable arm naturally will fall centered by the hinge-point of movable arm and fixed arm, and at this moment the eave tile of movable arm will catch on product.Put down locking arm, the block medial surface on locking arm is allowed to withstand the lateral surface of fore shaft, according to gap between fixed arm and movable arm, rotational lock arm, at this moment adjusting screw(rod) will enter or go out in setting nut, allows the gap between fixed arm and movable arm be in minimum rating, hoisting fixture, fixture will clamp product, and product is put into assigned address.
