Detailed Description
The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic drawings and illustrate the basic structure of the present invention only in a schematic manner, and thus show only the components related to the present invention.
Referring to fig. 1-3, the embodiment discloses a main jacking cylinder frame for fabricated pipe jacking construction, which comprises a lower connection 1; the number of the L-shaped frame bodies 2 is two, and the L-shaped frame bodies are symmetrically spliced at two ends of the lower connecting body 1 to form a U-shaped whole; wherein the L-shaped frame body 2 is formed by sequentially splicing a lower frame 21, a middle frame 22 and an upper frame 23; a plurality of oil cylinder holes 2a are arranged at intervals along the outline of the L-shaped frame body 2, and clamp pieces 3 are arranged at two ends of each oil cylinder hole 2a; the clamp member 3 includes a U-shaped clamp 31 riding on the outer periphery of the cylinder bore 2a and two fixing blocks 32 fixed to the L-shaped frame 2, and the U-shaped clamp 31 and the two fixing blocks 32 are fixedly connected by nuts.
Above-mentioned structure has adopted the assembled design, and with the whole seven sections little support bodies of linking 1, two lower framves 21, two well framves 22 and two upper cradles 23 totally of dividing into of hydro-cylinder frame, adopt the mode of concatenation to fix between the adjacent little support body, have easy dismounting, the convenient advantage of transportation. The distribution of oil cylinder hole 2a is in lower carriage 21, on well frame 22 and the upper ledge 23, be used for installing hydro-cylinder 6, and usable clamp piece 3 is consolidated hydro-cylinder 6, U type clamp 31 that both ends inserted in fixed block 32 promptly can fasten hydro-cylinder 6 on L shape support body 2, stability and fastness after with 6 installations of improvement hydro-cylinder, because of the design that adopts this kind of mode, hydro-cylinder 6 and hydro-cylinder frame are whole can install in advance before dispatching from the factory, little support body (get rid of down link 1) and the hydro-cylinder 6 that corresponds can not open the transportation promptly, this space that just makes to occupy is littleer, after transporting the scene, every little direct unit mount of support body can, the equipment is more efficient.
The specific splicing mode is as follows: the two ends of the lower connecting rod 1, the two ends of the lower frame 21, the two ends of the middle frame 22 and the lower end of the upper frame 23 are provided with butt joint plates 4, and the butt joint plates 4 are provided with bolt holes.
The butt joint plates 4 are arranged on the small frame bodies and are matched with high-strength bolts for connection, so that the whole oil cylinder frame can be conveniently assembled, any welding work is not needed, and the safety is higher; when the support is dismounted, the high-strength bolts screwed out of the bolt holes can realize the separation of the small support bodies. In order to ensure the installation stability of the lower frame 21, the middle frame 22 and the upper frame 23 in the height direction, rib plates can be welded on the butt joint plate 4 of the middle frame 22, the connecting plate of the upper frame 23 and the connecting plate of the lower frame 21, so that the firmness of the butt joint plates 4 is enhanced, and further the construction safety is ensured.
The lower frame 21, the middle frame 22, and the upper frame 23 are provided with the lifting lugs 5.
Through installation lug 5, make things convenient for the hoist and mount construction, for the stability of further improvement hoist and mount, lug 5 is generally installed at the top of undercarriage 21, well frame 22, upper bracket 23, and the position of avoiding butt plate 4 is noticed, avoids interfering the influence hoist and mount operation.
The L-shaped frame body 2 is made of steel, and the surface of the L-shaped frame body 2 is provided with an anti-rust layer.
L shape framework 2 that steel made is high in strength, and life is of a specified duration, for example, the lower carriage 21 of this embodiment, well frame 22 and upper carriage 23 are channel-section steel welded frame column structure, and foraminiferous steel sheet is welded to both sides around this frame column structure, and the left and right sides welds the rice font and supports, and overall structure is firm, and low in manufacturing cost is honest and clean. The antirust layer can be a paint layer, the cost is low, and the attractive effect of the L-shaped frame body 2 can be improved.
Referring to fig. 4, an oil cylinder 6 penetrates through the oil cylinder hole 2a, and the jacking force of the oil cylinder 6 is 2000 KN-3000 KN; each L-shaped frame body 2 is provided with nine cylinder bores 2a; wherein the lower frame 21 is provided with four cylinder bores 2a, the middle frame 22 is provided with three cylinder bores 2a, and the upper frame 23 is provided with two cylinder bores 2a.
At present, the jacking force of the rectangular jacking pipe is mostly within 30000KN, the layout is suitable for most jacking pipe construction, and the uniform stress on two sides of the jacking pipe is ensured. It should be noted that the number of the cylinder bores 2a of the lower frame 21, the middle frame 22, and the upper frame 23 is not limited to the above description, and the number of the cylinder bores 2a may be arranged according to construction requirements.
Still referring to fig. 1, in some embodiments, the bottom of the lower frame 21 is provided with a pad groove 21a.
Due to the fact that the rectangular jacking pipes are large in size, the universality and reusability of the whole oil cylinder frame are considered. Only the length of the lower connecting part 1 needs to be changed in the aspect of width, and only the cushion block needs to be additionally arranged at the cushion block groove 21a in the aspect of height, so that the transformation cost is low, and meanwhile, the universality and the reusability of the oil cylinder frame are improved.
The present invention is not limited to the above specific embodiments, and for those skilled in the art, the above conception can be used without any creative work, and all the changes made fall within the protection scope of the present invention.
