Abstract
The invention discloses a handcart brake, which comprises a braking pressing bar, a cam turnplate, brake discs, pull bars, a brake pedal, a pedal holder and a pedal-restoring mechanism, the pedal-restoring mechanism is mounted on the pedal holder, and comprises a brake-releasing pedal, a front restoring baffle, a rear restoring baffle and a restoring spring, the front restoring baffle is connected with the rear restoring baffle through the restoring spring, moreover, both the rear restoring baffle and the front restoring baffle are kept in contact with the brake-releasing pedal, and the brake pedal and the brake-releasing pedal are both connected with the pull bars. The cost of the handcart brake is low; the handcart brake is light and durable, and the handcart brake is safe and reliable, and is convenient to assemble and maintain.
Description
Technical field
The present invention relates to a kind of hand barrow, particularly a kind of barrow arresting gear.
Background technology
Hand barrow is widely used in the service location of the mobile operation such as civil aviaton's in-fight service and train, hotel, hospital, hand barrow must be equipped with brake equipment, can brake in time also and can decontrol in time braking in use, in order to can in use stablize and park, the most important thing is to guarantee hand barrow being perfectly safe in use, so barrow arresting gear is than indispensable device in hand barrow.
summary of the invention:
Existing barrow arresting gear, especially the hand barrow of applying on aviation or railway, its brake device structure complexity, and also major part adopts metal casting in a large number, its shortcoming is: the design of part complexity, corresponding manufacturing process also complicated, processing capacity is large, cost is high; Heavy Weight; The foundry goods easy fracture, cause fault; Be difficult for maintenance and repair.
Technical matters to be solved by this invention, design a kind of barrow arresting gear that can address the above problem exactly.
The technical scheme of technical matters of the present invention is:
A kind of barrow arresting gear, comprise the brake depression bar, cam turntable, brake disc, tie rod, brake pedal, pedal support and pedal reset attachment, described pedal reset attachment is arranged on pedal support, described pedal reset attachment comprises the brake off pedal, described pedal reset attachment also comprises the front apron that resets, back shield and retracing spring reset, to reset front apron and the back shield that resets of described retracing spring links together, and described back shield and the brake off pedal of resetting kept in touch, described brake pedal all is connected with tie rod with the releasing brake pedal, during drag, trample brake pedal, described brake pedal drives the tie rod motion, tie rod drives the cam turntable motion, boss pushing tow brake depression bar on described cam turntable moves, and the maintenance boss is to the pushing tow state of brake depression bar, the brake depression bar drives brake disc when moving and moves and brake disc is contacted with wheel, make the go-cart braking, during brake off, trample the brake off pedal, described brake off pedal drives tie rod and moves, tie rod drives the cam turntable motion, boss on described cam turntable leaves brake lever, remove the pushing tow state of boss to the brake depression bar, the brake depression bar sets back, the brake depression bar drives brake disc when setting back and moves and make brake disc leave wheel, make go-cart brake off state, when the boss on described cam turntable leaves brake lever, retracing spring recovers state of nature and drives the back shield motion that resets, and the back shield that resets drives brake pedal and resets.
Described barrow arresting gear, described brake off pedal, brake pedal are when surmounting reset position, and the front apron that resets makes brake off pedal, brake pedal return to normal reset position under the elastic potential energy effect of retracing spring.
Described barrow arresting gear, described brake off pedal, brake pedal, pedal support adopt enhancing nylon injection-molding part to make.
Described barrow arresting gear, described brake off pedal, brake pedal, pedal support adopt aluminium alloy extrusions to make.
Described barrow arresting gear, described cam is made by the corrosion-resistant steel blanked part.
The invention has the beneficial effects as follows: design of part is simple, and processing capacity is little, processing technology is simplified, and cost is low; Reduce the light-duty sturdy material that amount of parts forms and part adopts, and then alleviated weight and part is sturdy and durable; The part high conformity, safe and reliable, assemble easy to maintenance.
