Abstract

A rotary distributor belongs to the distributors for communicating a lorry crane and a vehicle crane and connecting upper and lower vehicles. The distributor comprises a core shaft, a control element, a pressing device, a brush assembly and a distribution body, wherein the distribution body is sleeved outside the core shaft, a longitudinal hole, a transverse hole and an oil guide slot are formed on the core shaft, the transverse hole is formed on the distribution body, and the transverse hole is corresponding to the transverse hole and the oil guide slot on the core shaft; the control element is connected between the distribution body and the core shaft, the pressing device is connected at the core shaft and the upper end of the control element, and the brush assembly is connected at the upper end of the pressing device. The rotary distributor has the advantages that the rotary distributor can prolong the service life of the distributor on the lorry crane and the vehicle crane to the maximum extent, simultaneously save a great amount of processing and maintenance cost, and improve the product quality and the credibility; the distributor has simple structure and practicality, and the back repair rate is currently reduced to be lower than 0.5 percent from more than 50 percent, thereby prolonging the service life of the lorry crane to the maximum extent and having convenient detachment, maintenance, replacement and assembly.

Description

The revolution distributing box

Technical field

The utility model relates to a kind of lorry-mounted crane and the car hosit continuous distributing box of getting on or off the bus, particularly a kind of revolution distributing box of linking up.

Background technology

At present, on lorry-mounted crane and car hosit, play the continuous distributing box of getting on or off the bus mandrel, control element, distributing box are arranged, as shown in Figure 1, divide part to be socketed in outside the mandrel, control element is connected on the mandrel, oil guide groove is arranged on mandrel, control element is between oil guide groove, and control element is uses O-ring seals, weares and teares easily and causes oozing between the epitrochoidal chamber and scurry the oily work effect that influences; Divide on the part block is arranged, block is a T shape piece, there is pressing plate bottom at T shape piece, pressing plate is fixed on the turntable, and T shape piece is to press by the pressing plate that is fixed on the turntable, to prevent to distribute body play and cause the fluid between the epitrochoidal chamber to scurry the work of influence mutually up and down, requirement on machining accuracy to pressing plate in the work is very high, the Mismachining tolerance of pressing plate is easy to cause cannot keeps under control T shape piece, thereby causes processing technology complicated, strengthens tooling cost; Because distributing box is in the heart portion of lorry-mounted crane and car hosit, thereby, because of the damage of distributing box causes the demolition, repair, replacement of distributing box, assembling all very difficult.

The utility model content

The purpose of this utility model is to provide a kind of demolition, repair, replacement, assembling all to turn round distributing box easily.

The technical solution of the utility model is: distributing box comprises mandrel (1), control element (2), pinch device (3), brush assembly (4), divides part (5), divide part to be socketed in outside the mandrel, hole longitudinally, horizontal hole and oil guide groove are arranged on the mandrel, divide on the part horizontal hole is arranged, hole and oil guide groove horizontal on this horizontal hole and the mandrel are corresponding, between minute part and mandrel, be connected with control element, pinch device is connected the upper end of mandrel and control element, is connected with brush assembly in the upper end of pinch device.

Described control element (2) includes wear-resistant pad (2.1), orienting sleeve (2.2), rotation envelope (2.3), wear-resistant pad, orienting sleeve, rotary seal are all between minute part and mandrel, wear-resistant pad is positioned at branch part bottom, orienting sleeve and rotary seal are positioned on the sidewall, and rotary seal uses lattice to enclose.

Described pinch device (3) includes bolt (3.1), wear-resistant pad (3.2), pressing plate (3.3), and pressing plate is connected with mandrel by bolt, and the edge of pressing plate is positioned at the upper end of branch part, between pressing plate and branch part wear-resistant pad is arranged.

Described minute part (5) include block (5.1), cylinder body (5.2), plinth (5.3), flange (5.4), block and plinth are arranged on cylinder body, in the upper end of cylinder body flange is arranged.

Beneficial effect: owing to adopted such scheme, the selected rotary seal of the utility model is that lattice enclose, replaced original O-ring seals, become face seal by original linear sealing, actv. has solved and has oozed the sealing problem of scurrying oil between the rotating object epitrochoidal chamber; Block and plinth are arranged on cylinder body, there is flange upper end at cylinder body, utilize and self push down the branch part, effectively prevented to divide the play up and down of part, working accuracy is reduced greatly, tooling cost has simply fallen at the end in processing technology, and demolition, repair, replacement, assembling are all convenient, have reached the purpose of this utility model.

Advantage: can prolong service life to greatest extent with the distributing box on car lifting and the car hosit, a large amount of processing and service expenditure have been saved simultaneously, product design and credit worthiness have been improved, this dispensing arrangement is simple, practical, repair rate by original surpass 50% drop to present below 0.5%, thereby prolong the service life of lorry-mounted crane to greatest extent, demolition, repair, replacement, easy to assembly.
