SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a but clearance regulation's fork truck stopper through the distance between the regulation brake shoe, compensates the clearance that the brake shoe friction disc wearing and tearing in-process produced, avoids braking reaction time's extension, ensures that braking distance can not the grow, has prolonged stopper life, the cost is reduced.
In order to achieve the above purpose, the utility model provides a following technical scheme: the utility model provides a fork truck stopper in adjustable clearance, includes brake bottom plate, two brake shoes, and two brake shoes set up in the left and right sides of brake bottom plate, the outside of brake shoe is equipped with the brake shoe friction disc, two the front end of brake shoe is equipped with brake wheel cylinder, extension spring, two the middle-end of brake shoe is equipped with the regulation hole, be equipped with adjusting screw on the regulation hole, two the rear end of brake shoe is equipped with the support, the support is through two eccentric shaft connection brake bottom plate, two the front end of brake shoe still is equipped with brake shoe positioning bolt, the front end of brake bottom plate is equipped with two clearance adjusting bolt that correspond brake shoe positioning bolt, be fixed with the clearance adjusting cam on the clearance adjusting bolt, the inner circle of brake bottom plate is equipped with the connecting hole.
Preferably, a pressure spring is sleeved on the gap adjusting bolt and arranged between the gap adjusting cam and the brake bottom plate.
Preferably, the gap adjustment cam abuts a brake shoe positioning bolt.
Preferably, one end of the adjusting screw is in limit connection with the brake shoe through two nuts, and the other end of the adjusting screw is in limit connection with the brake bottom plate through a nut and a gasket.
The utility model has the advantages that: the distance between the brake shoes is adjusted, the gap generated in the abrasion process of the friction plate of the brake shoes is compensated, the brake reaction time is prevented from being prolonged, the brake distance is ensured not to be increased, the service life of the brake is prolonged, and the cost is reduced.

Detailed Description
The following describes the gap-adjustable forklift brake according to the present invention with reference to the accompanying drawings. The following examples are exemplary and not intended to limit the scope of the claims.
Referring to fig. 1 to 4, the forklift brake with adjustable clearance of the present embodiment includes a brake base plate 1 and two brake shoes 2, the two brake shoes 2 are disposed on the left and right sides of the brake base plate 1, brake shoe friction plates 3 are disposed on the outer sides of the brake shoes 2, brake cylinders 4 and tension springs 5 are disposed at the front ends of the two brake shoes 2, adjusting holes 6 are disposed at the middle ends of the two brake shoes 2, adjusting screws 7 are disposed on the adjusting holes 6, support seats 8 are disposed at the rear ends of the two brake shoes 2, the support seats 8 are connected to the brake base plate 1 through two eccentric shafts 9, brake shoe positioning bolts 10 are further disposed at the front ends of the two brake shoes 2, two clearance adjusting bolts 11 corresponding to the brake shoe positioning bolts 10 are disposed at the front end of the brake base plate 1, clearance adjusting cams 12 are fixed on the clearance adjusting bolts 11, and a connecting hole 13 is disposed at. A compression spring 14 is sleeved on the gap adjusting bolt 11, and the compression spring 14 is arranged between the gap adjusting cam 12 and the brake bottom plate 1. The lash adjustment cam 12 abuts the brake shoe positioning bolt 10. One end of the adjusting screw 7 is in limit connection with the brake shoe 2 through two nuts, and the other end of the adjusting screw is in limit connection with the brake bottom plate 1 through a nut and a gasket.
During assembly, the brake base plate 1 is connected with a brake drum through the connecting hole 13, the brake shoe 2 is movably connected with the brake base plate 1 through the eccentric shafts 9 and the adjusting screw 7, and one ends of the two eccentric shafts 9, which are close to the brake shoe 2, are connected together through the fixing pin and the nut which are matched with the connecting plate. The brake shoe positioning bolt 10 is fixed on the brake shoe 2, the gap adjusting bolt 11 is fixed on the brake bottom plate 1, the gap adjusting bolt 11 is in limited connection with the gap adjusting cam 12 through a pressure spring 14 and a nut, and the gap adjusting cam 12 abuts against the brake shoe positioning bolt 10. The brake cylinder 4 is connected with an oil pipe, and the oil pipe is connected with a hydraulic brake controlled by a brake pedal.
When the brake drum is used, the brake wheel cylinder 4 is controlled to work through the brake pedal, the brake shoe 2 is pushed, the brake shoe friction plate 3 is enabled to press the inner side of the brake drum, braking force is generated through friction, and the purposes of speed reduction and braking are achieved. As the service life is prolonged, the abrasion of the brake shoe friction plate 3 is increased, the brake shoe friction plate 3 becomes thinner, the clearance distance between the brake shoe friction plate 3 and the inner side of the brake drum is increased, the brake reaction time is prolonged, the brake distance is increased, and the brake safety is influenced. Through twisting the head of clearance adjustment bolt 11 for clearance adjustment cam 12 follows the rotation, promotes brake shoe positioning bolt 10, makes brake shoe 2 shift to the outside, makes the clearance distance of brake shoe friction disc 3 and brake drum reduce, thereby through clearance adjustment bolt 11's setting, guarantees that the braking distance of stopper remains a safe distance throughout, has prolonged the life of stopper indirectly, the cost is reduced.
The scope of the present invention is not limited to the above embodiments and their variations. The present invention is not limited to the above embodiments, and other modifications and variations can be made without departing from the scope of the present invention.
