Abstract

The utility model relates to a pulling device for a rim retainer ring. The pulling device comprises a base and a machine frame arranged on the base; a lifting mechanism is sleeved on the machine frame; and one side of the lifting mechanism is connected with a rim positioning mechanism through a rotary drum. The pulling device is characterized in that a connecting plate is arranged on the base; the connecting plate is positioned at one side end part of the rim positioning mechanism and is hinged with one end of an L-shaped swinging rod, and the other side end part of the rim positioning mechanism is hinged with a hydraulic cylinder; a push rod of the hydraulic cylinder is hinged with the turning part of the L-shaped swinging rod; the turning part of the L-shaped swinging rod is hinged with one end part of a connecting rod; a pressing block driven by a hydraulic motor is slantingly arranged at the other end part of the connecting rod; a pressing rod driven by the hydraulic motor is arranged at the other end of the L-shaped swinging rod; and the end part of the pressing rod is close to the pressing block to be favor of clamping the retainer ring. With the adoption of the pulling device, the retainer ring can quickly break away from the restraint of a rim, therefore, the operation is simple, safe and reliable.

Description

Retaining ring of rim opens pulling device

Technical field

The utility model relates to a kind of retaining ring of rim and opens pulling device, is applicable in the demolition works to retaining ring of rim.

Background technology

Nowadays, the load of truck is increasing, and this has just caused the tire failure rate also to strengthen; Be badly in need of and the goods that truck delivered all is the client, under the situation of damaged tyres, we can only be as soon as possible to its place under repair so that give the client with goods in the specified period; The thing that so repairing damaged tire at first need be done all should be understood that and exactly tire is dismantled, and back-up ring is removed (constraint that back-up ring is broken away from wheel rim); And existing instrument all is very simple and crude; And just be the withdrawing device of mechanization neither be very safe and reliable, can accidentally injure the operator, we have only design a kind of safe and reliable; And the high stripping assembly of efficient, could in the shortest time, back-up ring be disassembled.

Summary of the invention

The purpose of the utility model is to provide a kind of retaining ring of rim to open pulling device, and the utility model can fast speed breaks away from the constraint of wheel rim with back-up ring, and is simple to operate, safe and reliable.

The utility model is characterised in that: a kind of retaining ring of rim opens pulling device; Comprise base and be located at the frame on the base; Be arranged with lifting mechanism on the said frame, said lifting mechanism one side is connected with the wheel rim detent mechanism through rotating cylinder, and it is characterized in that: said base is provided with connecting panel; Said connecting panel is positioned at wheel rim detent mechanism one side end and L shaped fork one end is hinged, and end side and hydraulic actuating cylinder are hinged, and the portion of turning of said hydraulic actuating cylinder push rod and L shaped fork is hinged; The portion of turning of said L shaped fork and connecting rod one end are hinged, and said connecting rod the other end tiltedly is provided with a briquetting by fluid motor-driven; The said L shaped fork other end is provided with a depression bar by fluid motor-driven; The end of said depression bar and briquetting are each other near being beneficial to clamp back-up ring.

Said connecting rod middle part is provided with handrail and is beneficial to order about the connecting rod upset.

The cross section of said briquetting is cydariform.

Said connecting panel is isosceles trapezoid.

The utlity model has reasonable in design, simple; It is also easy, not loaded down with trivial details to operate; Can fast speed back-up ring be broken away from the constraint of wheel rim, whole process is safe and reliable, has good value of service and practical value.

Among the figure: 1 is base; 2 is connecting panel; 3 is L shaped fork; 4 is hydraulic actuating cylinder; 5 is connecting rod; 7 is briquetting; 8 is depression bar; 11 is frame; 12 is lifting mechanism; 13 is rotating cylinder; 14 is the wheel rim detent mechanism; 31 for the portion of turning of L shaped fork; 41 is the hydraulic actuating cylinder push rod; 51 is handrail; 61,62 is HM Hydraulic Motor; A is a back-up ring; B is a cover tire; C is a wheel rim.

The specific embodiment

For letting the above-mentioned feature and advantage of the utility model can be more obviously understandable, hereinafter is special lifts embodiment, and cooperates appended graphic elaborating as follows.

With reference to legend; A kind of retaining ring of rim opens pulling device, comprises base 1 and is located at the frame 11 on the base 1, is arranged with lifting mechanism 12 on the said frame 11; Said lifting mechanism 12 1 sides are connected with wheel rim detent mechanism 14 through rotating cylinder 13, it is characterized in that: said base 1 is provided with connecting panel 2; Said connecting panel 2 is positioned at wheel rim detent mechanism 14 1 side ends and L shaped fork 3 one ends are hinged, and end side and hydraulic actuating cylinder 4 are hinged, and said hydraulic actuating cylinder push rod 41 is hinged with the portion of turning 31 of L shaped fork; The portion of turning 31 and connecting rod 5 one ends of said L shaped fork are hinged, and said connecting rod 5 the other end tiltedly are provided with a briquetting 7 by HM Hydraulic Motor 61 drivings; Said L shaped fork 3 other ends are provided with a depression bar 8 by HM Hydraulic Motor 62 drivings; The end of said depression bar 8 and briquetting 7 are each other near being beneficial to clamp back-up ring A.

Said connecting rod 5 middle parts are provided with handrail 51 and are beneficial to order about connecting rod 5 upsets.

The cross section of said briquetting 7 is cydariform.

Said connecting panel 2 is isosceles trapezoid.

The use of the utility model is for to stretch into depression bar between back-up ring and the cover tire B, and cover tire is pressed down; And the upset connecting rod, make briquetting and depression bar cooperating, back-up ring is clamped; Drive hydraulic actuating cylinder (like the direction of arrow of Fig. 4, promptly accomplish L shaped fork is deviated from the one rollover commentaries on classics of wheel rim detent mechanism, the part of back-up ring is pulled out) again; Make back-up ring break away from the constraint of wheel rim C, drive the wheel rim detent mechanism at last and make its rotation, so far; Can back-up ring be broken away from wheel rim fully, reach the design goal of this innovation; Among the utility model one embodiment, the point of action of the briquetting of mode of operation and depression bar and back-up ring is the shortest, like this can more effective clamping back-up ring, can sideslip, avoided bringing unnecessary danger to the workmen.

The above is merely the preferred embodiment of the utility model, and all equalizations of being done according to the utility model claim change and modify, and all should belong to the covering scope of the utility model.
