Abstract
The invention discloses an elevator braking device and belongs to the technical field of hosting device design. The elevator braking device comprises a handle, a brake rod, a sleeve cover, a brake pad, a brake wheel and brake leather. The handle and the brake rod are fixedly connected together and arranged to be perpendicular to each other. The sleeve cover is fixed to an elevator base. A round hole is machined in the right side of the sleeve cover. The left end of the brake rod is inserted into the hole. The left end face of the brake rod is squeezed with the brake pad. When an elevator works, the brake pad and the brake wheel are separated. When braking is required, the brake rod moves leftward to squeeze the brake pad, so that the brake pad moves leftward along with the brake rod to be squeezed with the brake wheel; the friction force between the brake rod and the brake pad is increased, so that the brake wheel stops rotating; and the brake wheel and a driving shaft of the elevator are fixed together. According to the elevator braking device, the handle is convenient to mount and demount; and the device is simple in structure, convenient to operate, large in braking area and good in braking effect.

Bother, many employings hook weight when hoisting heavy, and for being not provided with using specially
Some of structure in hook have been difficult in weight, lifting action, or cause during lifting
Damaging, some place is also performed to rest during weight lifts by crane, and weight to be made lifts by crane
Process can realize resting, it is necessary to increases brake unit, conventional brake unit knot on device
Structure is complicated, and braking reliability is poor, and braking effect is undesirable.
Summary of the invention
The purpose of the present invention is contemplated to overcome the defect of prior art, devises a kind of elevator
Brake unit.
Solve the technical problem that required by the present invention and can be achieved through the following technical solutions:
A kind of brake for elevator device, including handle, brake bar, described handle and described braking
Bar is fixed together, and both are vertically arranged, also include upper shield, brake(-holder) block, braked wheel,
Braking skin, described upper shield is fixed on elevator bases, and the right side of described upper shield is machined with circular hole,
The left end of described brake bar inserts from this hole, and left side extrudes with described brake(-holder) block, top lander
When making, described brake(-holder) block separates with described braked wheel, and when needing braking, described brake bar moves to left crowded
Press described brake(-holder) block that described brake(-holder) block is moved to left with it to extrude, between the two with described braked wheel
Frictional force increase described braked wheel stopped operating, the driving of described braked wheel and elevator
Axle is fixed together.
Described brake bar is threaded hole, the end of described handle near the external cylindrical surface of right-hand member
Being machined with external screw thread, described handle i.e. uses with described brake bar threadeds.
The bar portion of described brake bar is machined with external screw thread, screws in the screwed hole of fixing seat, Gu
Reservation maintains static.
Described brake(-holder) block is designed to arcuate structure, and this arcuate structure is the annulus of 1/5th.
The intrados of described brake(-holder) block is fixed with described braking skin.
Owing to have employed above technical scheme, present invention have the advantage that
Use set by handle, brake bar, upper shield, brake(-holder) block, braked wheel, the skin-deep combination of braking
The brake for elevator device of meter, brake bar is threaded hole, hands near the external cylindrical surface of right-hand member
The end of handle is machined with external screw thread, and handle is convenient to mount and dismount, and the bar portion of brake bar is machined with external screw thread,
During installation, the external thread rotary of brake bar is combined in the screwed hole of fixing seat, brake bar simple in construction,
Easy to operate, brake(-holder) block is designed to arcuate structure, and this arcuate structure is the annulus of 1/5th,
Brake area is big, and the intrados of brake(-holder) block is fixed with braking skin, owing to braking the coefficient of friction of skin
Greatly, therefore this brake unit good braking effect.
Accompanying drawing explanation
Fig. 1 is present configuration schematic diagram；
In figure each assembly and reference be respectively as follows: 1, handle；2, brake bar；3, upper shield；
4, brake(-holder) block；5, braked wheel；6, braking skin.
Detailed description of the invention
For the technological means making the present invention realize, creation characteristic, reach purpose and be prone to effect
Understand and understand, below in conjunction with being specifically illustrating, the present invention is expanded on further.
A kind of brake for elevator device, including handle 1, brake bar 2, upper shield 3, brake(-holder) block 4,
Braked wheel 5, braking skin 6, handle 1 is fixed together with brake bar 2, and both are vertical
Arranging, rapid operation is convenient, and upper shield 3 is fixed on elevator bases (being not drawn in figure), set
The right side of lid 3 is machined with circular hole, and the left end of brake bar 2 inserts from this hole, left side and braking
Sheet 4 extrudes, and during elevator work, brake(-holder) block 4 and braked wheel 5 separate, when needing braking, and system
Lever 2 moves to left extruding brake(-holder) block 4 and brake(-holder) block 4 is moved to left with it extrude with braked wheel 5, and two
Frictional force increase between person makes braked wheel 5 stop operating, and braked wheel 5 drives with elevator
Moving axis is fixed together, then drive shaft stops operating, and elevator stops enhancing action.
Brake bar 2 is threaded hole near the external cylindrical surface of right-hand member, the end processing of handle 1
Having external screw thread, handle 1 i.e. uses with brake bar 2 threadeds, and handle 1 is convenient to mount and dismount.
