Abstract

Predmetom vynálezu je stahovač segmen tov, určený predovšetkým k sfahovaniu seg mentov banskej ocel'ovej výstuže před utiah- nutím jej spojovacích prkov. Zaradením sta hovač a segmentov do technológie budova- nia výstuže sa dosiahne, že pri utahovaní spojovacích prvkov nie je potřebné vytvárať tak velké utahovacie momenty. Získává sa vačšia stabilita výstuže. Vyrovnávajú sa ne rovnosti, vznikajúce pri výrobě segmentov a ich vzájomné dosadnutie je priaznivejšie. Stahovač segmentov pozostáva z telesa sťa- liovača, rukovate, ktorá je umiestnená v boč- nej časti telesa stahovača, je s ním spoje ná pomocou dvoch spojok rukovate a je ňou vedený kanál spatnej vetvy a zaústěná hadica spatnej vetvy, pevného háku a boč ného háku, pričom hornou spojkou je ve dený kanál spatnej vetvy a hydraulické hadice a kábel sú umiestnené v spodnej čas ti stahovača segmentov s vývodom oriento vaným v smere pozdlžnej osi stahovača.The object of the invention is a segment puller, intended primarily for tying segments of mining steel reinforcement before tightening its connecting beams. By including the puller and segments in the reinforcement construction technology, it is achieved that when tightening the fasteners, it is not necessary to create such large tightening torques. Greater stability of the reinforcement is obtained. Inequalities arising during the production of segments are compensated and their mutual insertion is more favorable. The segment puller consists of the body of the puller, the handle, which is located in the side part of the puller body, is connected to it by means of two clutches of the handle and is guided by the channel of the back branch and the mouthed hose of the back branch, a fixed hook and a side hook, while the upper coupling is the channel of the back branch, and the hydraulic hoses and cable are located at the bottom of the segment puller with outlet oriented in the direction of the longitudinal axis of the puller.

Description

The subject of the invention is a segment puller, intended in particular to pull down the segments of the mine steel reinforcement before tightening its joining elements. By incorporating the puller and the segments into the reinforcement-building technology, it is achieved that when tightening the fasteners it is not necessary to produce such high torques. More reinforcement stability is obtained. They compensate for the inequalities that arise in the production of the segments and are more favorable to each other. The segment puller consists of a trimmer body, a handle which is located in the side of the puller body, is connected to it by means of two handles of the handle and is guided by the channel of the return leg and the outlet hose of the return leg, the fixed hook and the side hook, the upper connector being guided the return leg channel and the hydraulic hose and cable are located at the bottom of the segment puller with the outlet oriented in the direction of the longitudinal axis of the puller. 2

The invention solves the segment puller, intended in particular for pulling the segments of the mine steel reinforcement before tightening its connecting elements using hydraulic power and moving it by moving the piston with the electromagnetic movement control.

So far known devices of a similar kind are designed so that they are very uncompact and bulky, hampering especially in mining operations. The hydraulic cylinder inlet hoses are oriented in different directions, hampering the segment withdrawal. The retractable hooks have a rigid structure so that they are very difficult and difficult to handle. As a rule, the handle is located at the bottom, which increases both the length of the puller, the handle hampers the inlet hoses, and technological problems also arise, as insertion hooks are difficult to set up and the puller is worsened.

The aforementioned drawbacks are eliminated by the segment puller according to the invention, which consists in that it consists of a puller body, a handle, which is located in the side part of the puller body and is connected to it by means of two handles of the handle and is guided by the return branch channel and mouthed. the return hook hose of the fixed hook, wherein the upper link handle is the return duct channel and the hydraulic hose and the cable are located at the bottom of the segment damper with the outlet oriented in the longitudinal axis of the segment damper. By being located in the side portion of the segment puller body, the overall length of the segment puller is reduced, as well as the more advantageous spatial arrangement in the reinforcement. The handle does not interfere with hoses and cables. By solving the fixed and rotating hooks, both hooks can be positively stacked behind the gripping segments of the reinforcement segments, as one of them can be folded up and the rigid hook inserted first by a slight twist, and the hooks can be swiveled. The orientation of the hoses and the cable in one direction is advantageous, thus greatly simplifying the operation of the puller, all three elements can be mechanically, e.g. To simplify and fine-tune the puller, the feed of the return branch channel in the handle, as well as in the upper clutch and the pressure branch channel, will contribute considerably to the lower clutch.

An example of an embodiment of a segment puller is shown in the attached drawing. FIG. 1 is a partial cross-sectional side view of FIG. 2;

The body of the puller 1 is connected to the handle 16, by means of the upper clutch 19 and the lower clutch 6. In the body of the puller 1 there is located a piston 2 connected to the piston 13. In the upper part there is a lid 3 secured by a locking ring 12. On the outer part of the puller body 1, the fixed hook 8 is fixed, and also by means of a pin 5 a rotatable hook 4, which encircles the segments 9. The handle 16 is provided with a handle lid 11, through which two buttons 7 are led to its surface. , connected by a three-pole socket 10 and also a return line hose 18. The hose of the pressure branch 17 is connected to the lower coupling 6. Other elements, such as pipes, may be used instead of the hose.

The force of the reinforcement segment puller is controlled by the microswitches 14 located in the handle 16. By pressing the button 7, the position of the electromagnetic distributor located in the area of the hydraulic aggregate is switched outside the segment puller, the hydraulic fluid flows into one of the hoses, controls the movement of the piston rod 2 which he moves to segments 9 and pushes them together. When the second button 7 is pressed, the piston 2 is retracted and the segment retractor can be removed from the segments 9.
