Abstract

The utility model discloses a special connecting part for fixing a hydraulic bracket, comprising parts 1, parts 3 and parts 2, wherein one end of each part 1 is inserted in a fixed hole of a flat vehicle; the other end of the part 1 is provided with a connecting hole; one end of each part 3 is inserted in the fixed hole of a bracket base; the other end of the part 3 is provided with a connecting hole; and the parts 2 are inserted in the connecting holes of the parts 1 and the parts 3, and connected with the part 1 and the part 3. The bracket is arranged on the flat vehicle, the parts 3 are arranged in the fixed holes at four corners of the bracket base; the parts 1 are arranged at the corresponding four corners at two sides of the flat vehicle; and the parts 1 and the parts 3 can be fastened by inserting the parts 2. The special connecting part can be used simply and conveniently, is not easy to loosen during the transporting process, has high strength, can be used for solving the difficult problem that the bracket is well fixed on the flat vehicle, and can be used for providing reliable technical conditions for the transportation safety of large equipment, thus providing reliable guarantee for the smooth installation of mining surfaces.

Description

Hydraulic support is special connecting piece fixedly

Technical field

The utility model relates to a kind of support bracket fastened special tool, specifically is that a kind of support is gone into the well when transporting, with the fixing fixed connecting piece that uses of flat car.

Background technology

As shown in Figure 1, existing support is the fixing thick clamping plate of 16mm that adopt on flat car, the M30 bolt, wire tensioner (spending blue bolt) is fixed, the support fixed form is that the support that will need earlier to fix requires to be put on the flat car according to center of gravity, after support is put well, two caps of pad are propped framework below passing framework, guarantee that the flat car place of meeting and discussing connects in the smooth patchhole of car latch energy, at first M30 * 80 high-strength bolts put a pad and fill in the bracket base front end elliptical aperture, in the flat car fixing hole, fill in simultaneously M30 * 80 high-strength bolts 6 of a shell tool equally, use junction plate 7 that two bolts are fastening then; Fixing φ 26 * 92 round-link chains 8, wire tensioner 9 and two φ 26 * 92 split rings 10 of adopting of back-end support are linked to be an integral body to support tail boom side guard board and flat car rear end.After support passes through knick point, wire tensioner 9 is loosening easily, and being connected and fixed of wire tensioner 9 and support caving shield side guard board adopted the hook (split ring) of stopping, loosening easily, disengagement in the transportation, cause support 3 to overturn, stay big potential safety hazard for the fixing and transportation of support.For this reason, it is necessary designing a kind of reliable support dedicated fixed part.

Summary of the invention

In order to overcome the hidden danger that exists in the existing connected mode, the utility model provides fixedly special connecting piece of a kind of hydraulic support.

The utility model overcomes the above problems the scheme that is adopted: a kind of hydraulic support is special connecting piece fixedly, comprising:

One end inserts the parts one that have connecting hole on flat car fixing hole, the other end;

One end insertion bracket base fixing hole, the other end have the parts three of connecting hole;

The connecting hole link one of insertion parts one and parts three and the parts two of parts three.

During use, 1) reserves the fixing hole that special connecting piece is installed at truck; 2) according to the dedicated fixed hole design part three on the bracket base; 3) support is put on the flat car, support center of gravity and flat car center of gravity worst error are not more than 50mm, in bracket base Corner Strapped hole, install parts three, install parts one for corresponding four jiaos, undertaken fastening by two pairs of parts one of insertion parts and parts three on the flat car both sides.

Compared with prior art, hydraulic support described in the utility model fixedly special connecting piece have following characteristics: (1) is simple, convenient, practical; (2) be not easy in the transportation to become flexible; (3) intensity height.Thoroughly solved support intact fixing difficult problem on flat car, the robust techniques condition is provided for the main equipment transportation safety, for the smooth installation of adopting face provides reliable guarantee.At 5303,4308 with 2320 interviews are installed, result of use is good, good popularization and application prospect is arranged through the technician.

The specific embodiment

A kind of hydraulic support described in the utility model is special connecting piece fixedly, comprising: an end inserts the parts 1 that have connecting hole on flat car 1 fixing hole, the other end; One end insertion support, 3 base fixing holes, the other end have the parts 34 of connecting hole; The connecting hole of insertion parts 1 and parts 34, the parts 25 of link 1 and parts 34.Parts 25 adopt unit bolt nut, and parts 34 are slotted eyes with the fixing hole of support 3 bases.

Support is the special connecting piece fixed form fixedly: need fixing support 3 to require to be put on the flat car 2 according to center of gravity, after support 3 is put well, two caps of pad are propped framework below passing framework, guarantee that flat car 1 place of meeting and discussing connects in the smooth patchhole of car latch energy, insert in flat car 1 special hole with back part 1, parts 34 insert in the fixing special-purpose elliptical aperture of supports 3 bases, with parts 25 parts 1 and parts 34 connect and on the nut of M30 carry out fastening.Four angles of bracket base all need be fixed, so fixing each each the parts quadruplet of special connecting piece that needs of each support.
