Abstract
The utility model relates to braking brake technical field, disclose a kind of brake block, comprise the wear mark layer of definition, for allowing wear within described wear mark layer, forbid wear beyond described wear mark layer, described in forbid that the color of wear and/or the color of shape and/or size and described permission wear and/or shape and/or size are different.The utility model can see the wear mark of brake block intuitively, so that when brake block arrives wear mark, carrying out that just can be the fastest is changed.The convenience that improve brake block inspection simultaneously, also improves the Security of elevator.
Description
Technical field
The utility model relates to braking brake technical field, particularly relates to a kind of brake block.
Background technique
The stopping of elevator mainly produces frictional force to keep by friction plate clamping brake disc (or Brake drum) of break.And run for a long time along with elevator, the wear extent of brake block can be increasing, and when wear extent exceeds specified value, the braking moment of elevator brake will decline.The phenomenon that car skids will be there is when elevator overload like this, and the anxious stopping time, elevator can be there is and to stop the situation such as incessantly.
In order to prevent above-mentioned two situations, confirm with regard to needing the wear extent of engineering staff to break.When the thickness of brake block is less than minimum permission thickness, need to change brake block.Because the wearing and tearing of brake block are not very even, cannot just confirm that brake block cannot use by one-shot measurement.And due to the dismounting of brake block cumbersome.So exist due to procuratorial work is not in place or engineering staff is lazy situation and cause the situation that non-serviceable brake block is still using.
Current brake block is all the thickness size carrying out confirming brake block by the size at four angles of measurement brake block.Such measurement is more loaded down with trivial details.And owing to needing the operation being carried out by break disintegrating when measuring, relative operation more complicated and need special work.
And consider that the repair and maintenance cycle of break is 1 year, in the using process of a year, the thickness of brake block is slowly thinning.If lack the monitoring of pilot process like this, brake block thickness just below specified value, may continue use and there is security risk.If increase process monitoring comparatively to bother again, and still need to carry out disintegration operation.In addition, frequent dismounting break, because the improper meeting of operated by personnel causes the risk of the hydraulic performance decline of break.
Model utility content
In order to solve the problems of the technologies described above, the utility model provides a kind of brake block, changes the structure of brake block, the boundary that brake block allows wearing and tearing can be observed intuitively, reduce the time of brake block abrasion inspection, improve checking efficiency, the Security of hoisting elevator.
The technological scheme that the utility model is taked is:
A kind of brake block, comprise the wear mark layer of definition, for allowing wear within described wear mark layer, forbid wear beyond described wear mark layer, it is characterized in that, described in forbid that the color of wear and/or the color of shape and/or size and described permission wear and/or shape and/or size are different.
A kind of brake block, comprises the wear mark layer of definition, for allowing wear within described wear mark layer, forbid wear beyond described wear mark layer, it is characterized in that, near described wear mark layer, arrange conductor layer, the two ends of described conductor layer are connected to control circuit.
Further, the wire in described conductor layer is in shape of turning back continuously.
The beneficial effects of the utility model are:
(1) wear mark of brake block can be seen intuitively, so that when brake block arrives wear mark, carrying out that just can be the fastest is changed.The convenience that improve brake block inspection simultaneously, also improves the Security of elevator.
(2) can the abrasion condition of direct check brakes sheet, reduce the disintegration number of times of elevator brake, reduce Yin Weibao improper, and the risk causing break to damage.
Accompanying drawing explanation
Accompanying drawing 1 is view when brake block is normal in the utility model first embodiment;
Accompanying drawing 2 is the view in the utility model first embodiment after brake block wearing and tearing;
Accompanying drawing 3 is view when brake block is normal in the utility model second embodiment;
Accompanying drawing 4 is the view in the utility model second embodiment after brake block wearing and tearing;
Accompanying drawing 5 is view of brake block in the utility model the 3rd embodiment;
Accompanying drawing 6 is A-A cross-sectional schematic in accompanying drawing 5.
Label in accompanying drawing is respectively:
1. brake block; 2. wear mark layer;
3. allow wear; 4. forbid wear;
5. conductor layer; 6. wire.
Embodiment
Elaborate below in conjunction with the embodiment of accompanying drawing to the utility model brake block.
Embodiment one:
See accompanying drawing 1,2, brake block 1 comprises the wear mark layer 2 presetting definition, for allowing wear 3 within wear mark layer, is forbid wear 4 beyond wear mark layer.To wear 3 be allowed and forbid that the color of wear 4 is arranged to not identical, when permission wear 3 been has all has been worn and torn, through wear mark layer 2, arrive after forbidding wear 4, owing to forbidding that the color of wear 4 is different from allowing the color of wear 3, be easy to just make a distinction by naked eyes.Enable engineering staff's Timeliness coverage and change brake block 1.
Embodiment two
See accompanying drawing 3,4, similar with embodiment one, to wear 3 be allowed and forbid the shape of wear 4 or be sized to not identical, when permission wear 3 been has all has been worn and torn, through wear mark layer 2, arrival to forbid after wear 4, because the shape or size of forbidding wear 4 allow the difference of wear 3, is easy to just make a distinction by naked eyes.Enable engineering staff's Timeliness coverage and change brake block 1.
Above-described embodiment can be combined, and is mutually combined by color, shape and size, makes it allow engineering staff's Timeliness coverage brake block state of wear more easily.
Embodiment three
See accompanying drawing 5,6, with embodiment one, two similar, conductor layer 5 is set near wear mark layer 2, wire 6 in described conductor layer 5 is in shape of turning back continuously, the wire of shape of turning back can be rubbed in time when allowing wear to may wear to wear mark layer, and the two ends of wire 6 are connected to control circuit.When brake block may wear to conductor layer position, because wearing and tearing can make wire break.Now will give elevator signal, elevator can stop automatically, or reports to the police, and engineering staff, according to elevator halted state, changes brake block 1 in time.
Below be only preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
Claims (3)
1. a brake block, comprise the wear mark layer of definition, for allowing wear within described wear mark layer, be forbid wear beyond described wear mark layer, it is characterized in that: described in forbid that the color of wear and/or the color of shape and/or size and described permission wear and/or shape and/or size are different.
2. a brake block, comprising the wear mark layer of definition, for allowing wear within described wear mark layer, is forbid wear beyond described wear mark layer, it is characterized in that: near described wear mark layer, arrange conductor layer, the two ends of described conductor layer are connected to control circuit.
