Abstract
The invention discloses a support bar for trial assembling and adjusting of hydropower station tainter valve which consists of six units, including a jack device, a T-shaped screw thread stud locking mechanism, an outer steel sleeve, an inner steel sleeve, an upper hinge device and a lower hinge device. The support bar provided in the invention has large support force; extent of support force and adjusting length can be adjusted instantly; the supporting length can be longer than 20 metres; the support bar has fine rigidity and excellent stability, thereby locking support length continuously to be applicable to adjustment support of various positions. The support bar is applicable to reuse.
Description
Technical field
The present invention relates to a kind of support bar, particularly relate to the support bar of a kind of power station Segment gate manufacturing examination assembly unit adjustment usefulness.
Background technology
At present, because the Segment gate appearance and size in power station is all bigger, be subjected to the restriction of road transport condition, gate all by the more piece manufacturing, is transported to behind the scene, power station to install in the installation position again and is welded into integral body before dispatching from the factory.In the manufacture process of Segment gate before dispatching from the factory, it makes pre-assembly unit operation is in order to use gate to reach overall performance and the indispensable procedure of designing requirement, and it is smooth respectively to save the gate flap assembly unit when guaranteeing that gate is installed at the scene.The vertical erection method of gate flap is generally adopted in the pre-assembly unit of Segment gate manufacturing, and is highly bigger during vertical assembly unit because the appearance and size of gate is big and divide the more piece manufacturing, has more highly difficult in the high-altitude to every joint gate flap adjustment of forming gate.Conventional employing worker's steel or round steel support to adjust many inconvenience, need weld again fixing during adjustment at every turn, can not adjust immediately, the support bar application of force also inconvenience to bottom support point cutting weld seam, support bar also inconvenience is reused, and adjustment has brought inconvenience to gate flap.
Summary of the invention
The invention discloses a kind of support bar for trial assembling and adjusting of hydropower station tainter valve, comprise the upper hinge device, following hinge means, the outer steel sleeve pipe, interior steel sleeve, jack, upper bracket, lower carriage, T shape threaded stud locking mechanism, wherein, outer steel sleeve pipe and interior steel sleeve pivot bush unit, upper hinge device and following hinge means are separately positioned on the termination, the outside of outer steel sleeve pipe and interior steel sleeve separately, upper bracket and lower carriage then are arranged on outer steel sleeve pipe and the interior steel sleeve sleeve pipe separately, jack is arranged between the lower carriage, and fix by lock stud and lower carriage, upper bracket and outside, jack upper end are provided with block, T shape locking mechanism and lower carriage are fixed, and form by T shape screw nut and upper bracket and can regulate fixingly, jack and T shape locking mechanism are positioned at steel sleeve both sides correspondence position.
T shape threaded stud locking mechanism then is made up of T shape threaded stud and supporting T shape screw nut thereof.
Wherein, the length that is nested of outer steel sleeve pipe and interior steel sleeve is 1500mm, and the fit clearance between outer steel sleeve pipe and the interior steel sleeve is 0.3mm to 0.5mm.
They sup-port power provided by the present invention is big, support force size and to adjust length adjustable immediately, and bearing length can reach more than the 20m, good rigidity, and good stability, lock support length can adapt to the support adjustment of various orientation continuously, can reuse.
Description of drawings
Fig. 1 is a structure chart of the present invention.
The specific embodiment
1, a kind of support bar for trial assembling and adjusting of hydropower station tainter valve, comprise upper hinge device 1, following hinge means 11, outer steel sleeve pipe 2, interior steel sleeve 10, jack 4, upper bracket 3, lower carriage 6, T shape threaded stud locking mechanism, wherein, outer steel sleeve pipe 2 and interior steel sleeve 10 pivot bush units, upper hinge device 1 and following hinge means 11 are separately positioned on the termination, the outside of outer steel sleeve pipe 2 and interior steel sleeve 2 separately.Upper bracket 3 and lower carriage 4 then are arranged on outer steel sleeve pipe 2 and interior steel sleeve 10 sleeve pipes separately, jack 4 is arranged on the lower carriage 6 with T shape threaded stud locking mechanism and is positioned at support bar both sides correspondence position, jack 4 is fixing with lower carriage 6 by lock stud 5, T shape locking mechanism and lower carriage are fixed, and can regulate fixing by T shape screw nut 7,8 and upper bracket 3 formation.Can increase the adjustment stroke according to adjusting the required steel plate that is encased inside suitable thickness between jack 4 and the upper bracket 3, upper bracket 3 is provided with block with outside, jack 4 upper end simultaneously, prevents jack 4 upper ends and the outside slippage of backing plate.
T shape threaded stud locking mechanism is made up of T shape threaded stud 9 and supporting T shape screw nut 7 and 8 thereof.
1.5m about, to guarantee the stability requirement of support bar; Inside and outside steel sleeve fit clearance is got between the 0.3mm to 0.5mm; Support application of force trim lengths and adjust demand according to the lock gate leaf assembly unit and generally be decided to be about 200mm, when the positioning supports bar, but guarantee the be nested length of activity surplus and application of force fine setting of inside and outside steel sleeve; Jack is installed between the support of inside and outside steel sleeve, adjusts support bar length by the support application of force that acts on inside and outside steel sleeve during jack work.Do not adopt T shape threaded stud and supporting T-nut thereof to come stressed adjustment to be herein because: rotate T shape screw nut during its stressed adjustments and make support bar be subjected to torsion, support bar upper and lower side fixed point may be become flexible or change, and very little with the fine setting of the jack operation application of force to the stability influence of support bar.
11 moveable hinge base plate and the welding of lower support face are fixing, after reserving the adjustment amount of jack 4, upper hinge device 1 is fixing with the lock gate leaf proper site welding that needs to adjust, flexible convenient when guaranteeing that support bar is installed in this process, need earlier T shape screw nut 7 to be threaded to the position of threaded stud 9 by the top, T shape screw nut 8 is threaded to the position of threaded stud 9 by the bottom.It is flexible when support bar is adjusted gate flap by jack 4 work controls, when adjusting to the right place, because the functional performance of jack requires can not long-term stressed support, at this moment make threaded stud 9 and upper bracket 3 lockings by adjusting T shape screw nut 7 and 8, with not flexible of lock support, this section of jack 4 off-load back support rods is born support force by T shape threaded stud 9.As also adjusting, unclamp T shape screw nut 7 to correct position, jack 4 work are adjusted, adjust T shape screw nut 8 in case of necessity again and reserve the adjustment surplus.
Very little with the fine setting of the jack operation application of force to the stability influence of support bar, the accuracy in having guaranteed to adjust.The support bar upper and lower side is provided with articulated link mechanism, because the used support bar of Segment gate manufacturing examination assembly unit adopts the bearing diagonal mode, and the internal force influence that the variation of its angle brought the upper and lower side fixed point when articulated link mechanism had then solved the support bar length adjustment.
