Abstract

The utility model discloses an adjustable machine seat as a foundation for various equipment and machines. The top ends of the front, back, left and right sides of an original guard plate which is sheathed on a machine base are respectively added with a screw-type regulating plate. The screw hole of the screw-type regulating plate is penetrated with a fastening bolt with a conical tail which is matched with a corresponding cone position recess on the top beam of an internal sleeve. Four accurate regulating mechanisms are formed, which can regulate the height of the top beam accurately and independently. The screw-type accurate regulating mechanism has the advantages of simple structure and easy regulation, can realize stepless accurate fine regulation, vertically support and can stably and reliably bear heavy loads. The screw-type accurate regulating mechanisms can be standardized and produced with series to meet the installing requirements of various equipment.

Description

Adjustable machine seat

The utility model relates to a kind of base or support that is specifically designed to various device or machine, particularly relates to a kind of adjustable support of distance between the equipment depth of parallelism, verticality and equipment frame of can accurate adjusting in the machine room.

Because the installation work of communication facilities at present is also strict and perfect day by day to the installation specification and the technical requirement of various telecommunication apparatus all towards standardization and seriation development.As the support on permanent basis of communication main equipment, whether its structural design improves and can construction quality be guaranteed, and directly has influence on the duty and the serviceable life of main equipment, more and more causes design, builds and the attention of use department.Especially construction unit is strong day by day for the cry that original application traditional support requirement is for many years transformed.

The traditional support that uses as shown in Figure 1 now, be by the overcoat backplate 1 that is the Qian type and be the overcoat underbeam 2 of L type in the lower end, the left and right sides of overcoat backplate 1, and be embedded in the overcoat inboard, interior cover backplate 3 that can the slippage lifting and interior cover put the beams in place and 4 form, both sides and front at overcoat backplate 1 all are provided with shrinkage pool 5, are installed with the fishbolt 6 and the nut 7 of fastening interior cover backplate relative position in these shrinkage pools 5.The defective that the support of this structure exists have following some: 1. single side bolt clip fastens mode, makes the load-bearing of support and shock resistance all very limited.2. because these several fastening bolts belong to whole tuning means, can not realize fine adjustment, make institute's installed device levelness and verticality all can not reach the installation specification requirement, be difficult to adapt to the development need of current communications equipment room.3. because support can not accurate adjustment, can only use the filling pad of several different-thickness to carry out the choker block leveling during construction, labour intensity is big, and production efficiency is low, can not guarantee project progress.4. original support kind is single, and tuning range is again little, is difficult to adapt to complicated building environment, is seriously restricting the installation of various type equipment supporting.

The purpose of this utility model provides a kind of adjustable support that can realize Precision trimming.

Basic structure of the present utility model and present traditional support are similar, its improvements are: be respectively equipped with a screw-type on the top, both sides all around of overcoat backplate and adjust dull and stereotyped, in its threaded hole, be equipped with the tapered fastening bolt of afterbody, match with the dimension shape pit of corresponding site in the interior cover upper beam, constitute four and can independently accurately adjust the fine-tuning mechanism of going up depth of beam.

The utility model is to set up four relatively independent fine-tuning mechanisms to form on original support basis, simple in structure, easy to adjust, load-bearing is big and reliable, can make seriation, standardized product, satisfies various equipment installation requirements with different length, width.So the utility model is except as the basis of communication facilities, the support, also can be widely used in powering, the installation basis of plurality of devices in industry such as railway, metallurgy, machinery and the scientific research institutions.This device adopts the screw-type fine-tuning mechanism, and fitter's work was simplified, and abandons the pad that thickness differs, and improves installation effectiveness, reduces labor intensity, and can also realize accurate stepless fine setting by the inclined-plane of screw thread.Because each fine-tuning mechanism all is independent of each other, be the vertical support state, also equipped mechanical caging nut, be aided with original bolt of side fit again, constitute dual adjustment system, not only improve the bearing capacity and stable, the anti-seismic performance of support, the adjustment that also can make the levelness of equipment and verticality more accurately, reliable.

Fig. 1 is the stand structure stereographic map that uses now.

Fig. 2 is a structural perspective of the present utility model.

Fig. 3 is screw rod in the fine-tuning mechanism and a upper beam pit partial enlarged drawing among Fig. 2.

Fig. 4 strengthens the push rod structure sketch in the utility model.

Consult Fig. 2, the utility model also is the overcoat underbeam 2 that is the L type by overcoat backplate 1 that is the Qian type and lower end, the left and right sides thereof, and be embedded in the overcoat inboard, interior cover backplate 3 that can the slippage lifting and interior cover put the beams in place and 4 form, both sides and front at overcoat backplate 1 still are provided with

shrinkage pool

5,5 li fishbolt 6, nut 7 and pad 8, spring washers 9 that are equipped with fastening interior cover backplate 3 relative positions of these shrinkage pools.Be respectively equipped with a screw-type on forward and backward, the top, the left and right sides of overcoat backplate 1 and adjust flat board 10, this adjustment dull and stereotyped 10 can be adopted the angle bar welded structure, and welded nut 14 constitutes in dull and stereotyped 10 circular hole.In the threaded hole of this nut 14, be equipped with the tapered fastening bolt of afterbody 11 as accurate adjustment screw rod 11(referring to Fig. 3), its top cone angle can be 3 * 45 °, the fastening bolt 11 of adjusting the downside of flat board 10 is provided with set nut 12, so that after accurate adjustment is finished, tighten set nut 12, make the stationkeeping of accurate adjustment screw rod 11 constant.Be provided with pyramidal pits 13(referring to Fig. 3 in the put the beams in place position of 4 corresponding accurate adjustment screw rod 11 afterbody tapers of interior cover), the degree of depth of this pit can be the 2-3 millimeter, should be slightly less than the wall thickness of upper beam.Constituted independently fine adjustment mechanism of four of the utility model by above-mentioned adjustment flat board 10, accurate adjustment fastening bolt 11, nut 14 and set nut 12.

Because the utility model can constitute standardized series of products according to above-mentioned basic structure pattern, satisfy the equipment installation requirements of different size and size, put after underbeam reaches certain-length when inside and outside, when for example surpassing 600mm, the position is set up a reinforcement and is supported push rod therebetween, referring to Fig. 4.The top of this push rod 15 is still tapered, and its bottom then is a screw rod, screws in to be placed in the screw of the bolt column 16 on the underbeam, in the middle of the push rod is four directions or hexahedron, can take this to rotate push rod 15, make it to support and put the beams in place 4, guarantee that long upper beam still has enough rigidity and intensity.

The utility model has been made sample segment, tries out enforcement in Telecommunications Bureau Beijing inside, obtains the favorable comment and the welcome of designing unit and construction parts.
