Abstract
The utility model discloses a lifting device of a switch, and relates to the technical field of rolling equipment. The lifting device comprises a supporting base, an air cylinder and a connecting block, wherein a clamping head at the upper end of the connecting block is in clearance fit with a clamping groove formed in the lower face of a steel material rail, the clamping head can transversely swing in the clamping groove, the lower end of the connecting block is connected with a guide pillar of the air cylinder, and the lower end of the air cylinder is hinged to the supporting base. The rising motion and the falling motion of the switch are achieved through rising and falling of the guide pillar of the air cylinder, the lower end of the air cylinder is hinged to the supporting base, the clamping head at the upper end of the connecting block is in clearance fit with the clamping groove formed in the lower face of the steel material rail, and therefore it can be ensured that the switch has a certain deflection amount relative to the supporting base. Installation is convenient to conduct due to the fact that the connecting block is connected with the upper end of the air cylinder in a threaded mode. The lifting device replaces an existing structure including an air cylinder, a gear, a rack and a guide arm, and therefore on the premise that the rising and falling requirement is met, the rising and falling structure of the switch is better simplified. The lifting device has the advantages of being simple in structure, convenient to operate and maintain, economical and practical.
Description
Technical field
The utility model relates to steel rolling equipment technical field.
Background technology
The high line technological process of production is as follows: during steel billet is thick to 14 after heating furnace heating, offset after vertical mill and 4 pre-finish rolling rollings, by railway switch, send into flying shear topping (repeatedly rolling occiput cracking), entering 10 finishing mill rollings is that finished product and 3 sections of water cooling boxes enter air-cooled roller-way cooling down to collecting zone bailing by pinch roll, Laying head.Steel material rail end is provided with hinge, steel material before track enters flying shear by the railway switch jacking being connected with draw-in groove below track to tip position, after the steel material after flying shear crop enters finishing mill, return to bottom position, sampling action, realization order Rolling Production.
The problem existing at present: before flying shear, railway switch lifting is comprised of oscillating cylinder and gear, tooth bar and leading arm, complex structure, fragile, maintenance capacity is large, very easily causes and run heap steel, breaks in production in production.
Utility model content
Technical problem to be solved in the utility model be to provide a kind of simple in structure, easy to operate, be convenient to safeguard, economical and practical railway switch lowering or hoisting gear.
For solving the problems of the technologies described above, technical solution adopted in the utility model is:
A kind of railway switch lowering or hoisting gear, comprise supporting seat, cylinder and contiguous block, the draw-in groove matched in clearance that the dop of described contiguous block upper end and steel material track are provided with below, dop is energy teeter in draw-in groove, contiguous block lower end is connected with cylinder guide pillar, and described cylinder lower end and supporting seat are hinged.
Preferably, the dop of described contiguous block upper end is spherical crown shape.
Preferably, described contiguous block lower end is threaded with cylinder guide pillar.
Preferably, between described contiguous block and cylinder guide pillar, locking nut is set.
Preferably, described cylinder model is QGBZ125*60-MP3.
Preferably, described cylinder lower end and supporting seat articulated structure be, between the monaural of the ears of described supporting seat and cylinder lower end, is provided with bearing pin, described bearing pin axially parallel with the length direction of steel material track.
The beneficial effect that adopts technique scheme to produce is: by the lifting of cylinder guide pillar, realize the elevating movement of railway switch, the monaural of cylinder lower end is connected by bearing pin with supporting seat, draw-in groove matched in clearance under contiguous block upper end and steel material track, can make railway switch have certain beat amount around bearing pin, because there is the beat amount with track vertical direction in steel material in the operation of rolling, the locking nut arranging between contiguous block and cylinder guide pillar make between contiguous block and cylinder guide pillar be threaded more firm, the spherical cap-shaped structure steel material track base point contact at contiguous block top, contiguous block and interorbital frictional force are reduced, also avoid damaging steel material track lower surface simultaneously, oscillating cylinder before the utility model has substituted, gear, the structure of tooth bar and leading arm, meeting under the prerequisite of lifting requirement, the lifting structure of railway switch is more simplified, the utlity model has simple in structure, easy to operate, be convenient to safeguard, economical and practical feature.
Accompanying drawing explanation
Fig. 1 is the structural representation of an embodiment;
Fig. 2 is the use state diagram of Fig. 1;
In figure: 1-supporting seat, 2-cylinder, 3-contiguous block, 4-bearing pin, 5-locking nut, 6-steel material track, 7-draw-in groove, 8-guide pillar, 9-dop.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
A kind of railway switch lowering or hoisting gear as shown in Figure 1, comprise supporting seat 1, cylinder 2 and contiguous block 3, the dop 9 of described contiguous block 3 upper ends and draw-in groove 7 matched in clearance under steel material track 6, dop 9 is in the teeter of the interior energy of draw-in groove 7, the dop 9 of described contiguous block upper end is preferably spherical crown shape, can make the frictional force of 6, contiguous block 3 and steel material track reduce; Being connected to be preferably of contiguous block 3 lower ends and cylinder 2 guide pillars 8 is threaded, and at contiguous block 3 and 8 of cylinder 2 guide pillars, locking nut 5 is set, and plays reinforcement effect; Between the monaural of described supporting seat 1 and cylinder 2 lower ends, bearing pin 4 is set, described contiguous block 3 tops are spherical, the heavy cylinder that cylinder 2 model that preferably Jinan Jie Feite cylinder Co., Ltd produces is QGBZ125*60-MP3; Described cylinder 2 be preferably being connected of 1 of supporting seat hingedly, articulated structure is, between the monaural of the ears of described supporting seat 1 and cylinder 2 lower ends, is provided with bearing pin 4, described bearing pin 4 axially parallel with the length direction of steel material track 6.
By the lifting of cylinder 2 guide pillars 8, realize the elevating movement of railway switch, the monaural of cylinder 2 lower ends is connected by bearing pin 4 with the ears of supporting seat 1, the dop 9 of contiguous block 3 upper ends and draw-in groove 7 matched in clearance under steel material track 6, can make railway switch have certain beat amount around bearing pin 4, because there is the beat amount with steel material track 6 vertical direction in steel material in the operation of rolling, in Fig. 2, the arrow of steel material track 6 ends represents rolling direction, the locking nut 5 of 8 settings of contiguous block 3 and cylinder 2 guide pillars makes contiguous block 3 more firm with being threaded of 8 of cylinder 2 guide pillars, the spherical cap-shaped structure of the dop 9 at contiguous block 3 tops is that point contacts with steel material track 6 bottoms, the frictional force of 6, contiguous block 3 and steel material track is reduced, avoid damaging steel material track 6 lower surface, oscillating cylinder before the utility model has substituted, gear, the structure of tooth bar and leading arm, meeting under the prerequisite of lifting requirement, the lifting structure of railway switch is more simplified, the utlity model has simple in structure, easy to operate, be convenient to safeguard, economical and practical feature.
