Abstract
The invention discloses a hydraulic clamp. The hydraulic clamp comprises a clamp body with an air inlet and a brake unit, wherein the brake unit is composed of two brake plate assemblies opposite to each other with a gap therebetween; the brake plate assembly on a left side is fixed with the clamp body, while the brake plate assembly on a right side is connected with a bushing; a seal seat of which an outer surface is in seal fit with an inner cavity of the clamp body is fixed on the bushing; a seal cavity formed by the seal seat with the clamp body and the bushing communicates with an oil inlet; a disc spring is arranged between the bushing and the clamp body; moreover, the hydraulic clamp is characterized in that: the bushing is of a split structure and an exterior of the bushing is a hollow bushing; a push rod connected with the brake plate assembly is arranged at a left end within the inner cavity of the bushing, while a bolt that is externally connected with the bushing through threads and provided with an inner hole having at least one segment of section in a hexagonal or irregular shape is arranged on the right within the inner cavity; and an adjusting rod of which an external surface is matched with the inner hole in the hexagonal or irregular shape of the bolt is arranged in the inner hole of the bolt. The hydraulic clamp is capable of adjusting the travel of a friction plate, and is long in service life and low in cost.
Description
Technical field
The present invention relates to a kind of hydraulic tongs, particularly relate to a kind of tower machine brake hydraulic tongs.
Background technology
Current tower machine brake hydraulic tongs, can not adjust stroke after the friction disc wear in brake unit, can only integral replacing when friction force can not meet brake needs, and service life is short, cost is high.
Summary of the invention
For the above-mentioned defect existed in prior art, the present invention aims to provide and a kind ofly can adjust friction lining stroke, long service life, hydraulic tongs that cost is low.
To achieve these goals, the present invention is by the following technical solutions: it comprises the caliper, the brake unit that are provided with oil inlet, the slipper assembly that wherein brake unit leaves space by the two relative middle parts of cover forms, left hand brake board component and caliper are fixed, the slipper assembly on right side is connected with lining, this lining is fixed with the seal receptacle that outside face coordinates with caliper bore seal, and the annular seal space that sealing seat is formed with caliper, lining communicates with oil inlet; Disc spring is provided with between described lining and caliper; It is characterized in that: described lining is Split type structure, outside is the lining of hollow, in this lining inner chamber, left end is provided with the push rod be connected with slipper assembly, its right side is provided with and outside be connected with lining by screw thread and have the bolt that at least one section of cross section is six sides or irregularly shaped endoporus, is provided with six sides of outside face and this bolt or the adjust bar of irregularly shaped inner hole in this bolt bore.
Above-mentioned hydraulic tongs, wherein: described seal receptacle is provided with right seal ring, caliper on the other side is provided with left seal ring, this left seal ring inside face and sleeve surface gluing, sealing.
Above-mentioned hydraulic tongs, wherein: the inner chamber left end that described caliper holds disc spring is provided with the dust boot be connected as a single entity with described push rod.
Above-mentioned hydraulic tongs, wherein: the right side of described caliper inner chamber is opening, is disposed with the thrust plate fixing with caliper 1 and serum cap at opening part.
Compared with the prior art, in the present invention, lining is made Split type structure, be divided into lining, push rod, bolt, adjust bar, such rotary regulating lever can the position of free adjustment bolt in lining, thus make push rod drive the slipper assembly on right side to stretch out suitable stroke, thus can free adjustment brake weight size, also the wearing and tearing of friction lining are conveniently made up, namely the wearing and tearing be slightly unlikely to because of friction lining are changed, and long service life, has saved cost greatly.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present invention.
In figure: caliper 1, brake unit 2, dust boot 3, disc spring 4, bolt 5, left seal ring 6,
Right seal ring 7, thrust plate 8, serum cap 9, adjust bar 10, seal receptacle 11,
Lining 12, push rod 13.
Detailed description of the invention
Below in conjunction with accompanying drawing and specific embodiment, the invention will be further described:
As shown in drawings, hydraulic tongs of the present invention, comprise the caliper 1, the brake unit 2 that are provided with oil inlet, the slipper assembly that wherein brake unit 2 leaves space by the two relative middle parts of cover forms, and often overlaps slipper assembly and is made up of the one piece of friction lining be close to and one block of friction lining supporting plate; Left hand brake board component and caliper 1 are fixed, the slipper assembly on right side is connected with push rod 13, push rod 13 outer cover has lining 12, this lining is fixed with by nut the seal receptacle 11 that outside face coordinates with caliper 1 bore seal, sealing seat is provided with right seal ring 7, caliper 1 on the other side is provided with left seal ring 6, this left seal ring inside face and the surperficial gluing, sealing of lining 12, therefore, seal receptacle 11, left seal ring 6, right seal ring 7 form a closed annular seal space with caliper 1, lining 12, communicate with oil inlet; Disc spring 4 is provided with between described lining 12 and caliper 1; Be provided with on the right side of push rod 13 and outside be connected with lining 12 by screw thread and there is the bolt 5 that at least one section of cross section is six sides or irregularly shaped endoporus, be provided with six sides of outside face and this bolt or the adjust bar 10 of irregularly shaped inner hole in this bolt bore, adjust bar 10 role is similar to hex drive tool.In the present embodiment, the left end of bolt 5 endoporus is circular hole, and a right-hand member part and adjust bar 10 adopt six sides to coordinate.Be opening on the right side of caliper 1 inner chamber, be provided with the fixing thrust plate 8 of caliper 1 and serum cap 9, like this, be convenient to open regulating pushing rod stroke.The inner chamber left end that described caliper 1 holds disc spring 4 is provided with the dust boot 3 be connected as a single entity with described push rod 13, can effectively avoid dust to enter, affect product continuous firing.
It is of the present invention that to sketch principle of work of the present invention below in conjunction with accompanying drawing as follows.
When not having oil-feed instruction, the slipper assembly on right side, under the elastic force effect of disc spring 4, together with the slipper assembly in left side, is held the parts that need brake tightly, is reached braking effect.
After oil-feed instruction is opened, outside high-voltage oil liquid enters the annular seal space be made up of with caliper 1, lining 12 seal receptacle 11, left seal ring 6, right seal ring 7 by oil inlet, high pressure oil promote seal receptacle 11 overcome disc spring 4 elastic force, drive bolt 5, push rod 13 to move right together, the slipper assembly on right side is away from the slipper assembly in left side, no longer hold tightly, braking state is removed.
Principle of work of the present invention is obstructed oil brake, and logical Chinese pine opens.If be out of shape slightly the present invention, can realize logical oil brake, obstructed Chinese pine opens, and it also should in scope.
