Description

The horizontal Filtting device of heavy centre-hole jack

Technical field

Bridge engineering prestressed stretch-draw centre-hole jack handbarrow field.

Background technology

In bridge engineering prestress tensioning equipment, hydraulic jack uses centre-hole jack mostly.In the resistance to compression testing process of the various material such as verification, huge concrete structure, large-scale workpiece of jack, the main reaction frame that uses carries out, and reaction frame inner space is narrow and small, and the dismounting for centre-hole jack is very difficult.Because centre-hole jack is cylindricality single solid steel iron construction, very heavy, outer surface is bright and clean, usual crane and fork truck are moved, because crane volume is excessive, and in handling process, crane catches on the transverse direction that suspension ring can only realize jack and moves, and but cannot realize moving horizontally of jack, therefore move jack because place reason can not realize crane mostly in middle-size and small-size factory; When jack being arranged on the reaction frame inside of column formation, because top cover is arranged at reaction frame top, jack needs maintenance level to move out of reaction frame, in narrow space, fork truck cannot enter reaction frame inside, and jack cannot be placed on fork truck foot, thus in the level of reaction frame inside turnover moved for centre-hole jack very difficult, cause engineering disassembly process difficulty.

Summary of the invention

The utility model provide a kind of in the small space of reaction frame maintenance level move jack turnover the horizontal Filtting device of heavy centre-hole jack.

In order to achieve the above object, the technical solution adopted in the utility model is:

The horizontal Filtting device of a kind of heavy centre-hole jack, described Filtting device comprises V-type fixture and fork truck skate, it is characterized by: V-type fixture is made up of two v-shaped tubes and fastening leading screw, be used for gripper jack, skate is welded by thickness two rectangular tubes and forms, be through and fork truck pin make fork truck pin attenuate can enter reaction frame, be used for holding up jack; V-type fixture is made up of relatively the V-type clamp of two pieces of identical separation, and two V-type clamps be separated are coupled together formation entirety by two rhizoid thick sticks; V-type clamp is relatively welded by the GB rectangular tube mouth of pipe of two groups of four sections of same sizes and forms, and two long tubes of interlude weld with V-shaped, and the short tube at two ends welds so that the opposite direction mouth of pipe is relative with long tube respectively, and after completing, two short tubes are spatially located point-blank; Four perforation of two rhizoid thick sticks are on the short tube of two V-type clamps; Leading screw two ends use fastening nuts V-type clamp; Two fork truck skates are relatively welded by thickness two sections of rectangular tube mouths of pipe and form, extra heavy pipe and fork truck pin size supporting, tubule and V-type clamp same size.

Owing to have employed technique scheme, the beneficial effect acquired by the utility model is:

The utility model provides the horizontal Filtting device of a kind of heavy centre-hole jack, centre-hole jack is when narrow and small anti-supernatural power frame is inner, with V-type clamp jack, V-type fixture V degree can save space very greatly, there are four contact surfaces to increase frictional force with jack simultaneously, jack can be kept to stablize in handling process move ahead, the size that skate reduces fork truck pin put on by fork truck can enter supernatural power frame, be adjacent to V-type fixture and haul out jack, achieve and fork truck level just can be utilized to move out of jack in little space, solve an engineering dismounting difficult problem.

Detailed description of the invention

Below in conjunction with drawings and Examples, the utility model is described in further details:

The structural representation of the horizontal Filtting device of heavy centre-hole jack of the present utility model, as shown in Fig. 1,2,3,4,5,6,7,8, comprises V-type fixture and fork truck skate two parts.

V-type fixture of the present utility model forms an entirety by two V-type clamps 1 and two rhizoid thick sticks 2, fastening by nut 3; V-type clamp 1 is relatively welded by the GB rectangular tube mouth of pipe of two groups of four sections of 80mm*40mm and forms, long tube length is 210mm, short tube length is 70mm, two long tubes of interlude weld with the angle of 160 °, the short tube at two ends welds so that the angle mouth of pipe of reverse 170 ° is relative with long tube respectively, after completing, two short tubes are spatially located point-blank, entirety constitutes a V-type, because V-type v degree is very large close to the straight angle, space can be saved, V-type is configured with four contact surfaces simultaneously, can keep stable in jack handling process and move ahead; The long 500mm of M20mm selected by two rhizoid thick sticks 2; Four perforation are on the short tube of two V-type clamps, and penetrate rectangular tube, aperture is 22mm, and four lead to the hole site are consistent; Leading screw 2 is undertaken fastening by nut 3, and nut 3 selects M20mm; Fork truck skate is made up of two skates 4, skate 4 is relatively welded by thickness two sections of rectangular tube mouths of pipe and forms, extra heavy pipe is that the Plate Welding of the 2 groups four pieces thick 10mm of 145mm*500mm and 80mm*500mm forms, supporting with fork truck pin size, tubule is the GB rectangular tube of the long 400mm of 80mm*40mm, the mode that the two mouth of pipe docks with transverse and longitudinal is welded, and fork truck reduces the size that fork truck pin enters reaction frame inside after putting on skate.

When narrow and small anti-supernatural power frame is inner, centre-hole jack is clamped with V-type fixture, in order to prevent fixture destroy centre-hole jack surface in use can on fixture inner mast plastic pad, adjusting nut 3 gripper jack, skate put on by fork truck can enter supernatural power frame, is adjacent to V-type fixture bottom, above lifts slight distance and hauls out centre-hole jack, achieve and fork truck level just can be utilized to move out of centre-hole jack in little space, solve an engineering dismounting difficult problem.
