Description
【Technical field】
The utility model is related to the technical fields of safety detection device, and in particular to a kind of three roller elevating safeties detection dress
It sets.
【Background technology】
In three-roller, roller, in order to ensure lifting in place, needs to level detection apparatus to be detected in lifting.It is big at present
Travel switch is mostly used electrically to be detected, when electrically detection screw is in contact with travel switch, sends out signal in place.But
It is that travel switch is susceptible to failure, and detection is caused to be failed, so as to cause the generation of accident.
【Utility model content】
To solve the above problems, the purpose of this utility model is to provide one kind being provided simultaneously with electrical detection and mechanical position limitation
Three roller elevating safety detection devices.
To achieve the above object, the technical solution that the utility model is taken is：Three roller elevating safety detection devices, including set
The limit riser for fixing in three-roller on wheel seat is set, limits and is provided with detection transverse slat on riser, detect the upper surface of transverse slat
On be provided with electrical detection adjusting screw, detect and be provided with lower electrical detection adjusting screw, three-roller on the lower face of transverse slat
Wild wall on be provided with electrical detection travel switch and lower electrical detection travel switch, upper electrical detection travel switch with
The position of upper electrical detection adjusting screw is corresponding, the position phase of lower electrical detection travel switch and lower electrical detection adjusting screw
It is corresponding, it is provided with vertical long lumbar hole in the limit riser, mechanical position limitation axis is provided on the wild wall of three-roller, machinery
Limit shaft is threaded through in long lumbar hole.
Three roller elevating safety detection devices in the utility model are further arranged to：The upper end of the long lumbar hole is provided with
Adjusting screw on mechanical position limitation.
Three roller elevating safety detection devices in the utility model are further arranged to：The lower end of the long lumbar hole is provided with
Adjusting screw under mechanical position limitation.
Compared with prior art, the utility model has the advantages that：Three above-mentioned roller elevating safety detection devices,
Its is simple in structure, safe and reliable.It uses the double shield mode of electrical detection and mechanical position limitation, breaks down in travel switch
When, mechanical position limitation can also play the role of safety guarantee, ensure that the safety when lifting of three rollers.
【Description of the drawings】
Fig. 1 is the structural schematic diagram of the utility model.
In figure：1, it is fixed walk wheel seat, 2, limit riser, 3, detection transverse slat, 4, upper electrical detection adjusting screw, 5, lower electrical
Detect adjusting screw, 6, wild wall, 7, upper electrical detection travel switch, 8, lower electrical detection travel switch, 9, long lumbar hole,
10, mechanical position limitation axis, 11, adjusting screw on mechanical position limitation, 12, adjusting screw under mechanical position limitation.
【Specific implementation mode】
Three rollers elevating safety detection device described in the utility model is made below by specific embodiment further detailed
Thin description.
As shown in Figure 1, three roller elevating safety detection devices, including the limit for fixing on wheel seat 1 is set in three-roller
Riser 2 limits and is provided with detection transverse slat 3 on riser 2, detects and is provided with electrical detection adjusting screw on the upper surface of transverse slat 3
4, it detects and is provided with lower electrical detection adjusting screw 5 on the lower face of transverse slat 3, be provided with and power on the wild wall 6 of three-roller
Gas detects travel switch 7 and lower electrical detection travel switch 8, upper electrical detection travel switch 7 and upper electrical detection adjusting screw 4
Position it is corresponding, lower electrical detection travel switch 8 is corresponding with the lower electrical detection position of adjusting screw 5, and the limit is perpendicular
It is provided with vertical long lumbar hole 9 in plate 2, mechanical position limitation axis 10 is provided on the wild wall 6 of three-roller, mechanical position limitation axis 10 is worn
It is located in long lumbar hole 9.The upper end of the long lumbar hole 9 is provided with adjusting screw 11 on mechanical position limitation.The lower end of the long lumbar hole 9 is set
It is equipped with adjusting screw 12 under mechanical position limitation.
The operation principle of the utility model is：In use, wild wall 6 moves up and down, electrical detection part：Upper electrical inspection
Travel switch 7 and lower electrical detection travel switch 8 are surveyed as wild wall 6 moves up and down, when upper electrical detection travel switch 7 and
When upper electrical detection adjusting screw 4 is in contact, or electrically detection travel switch 8 connects with lower electrical detection adjusting screw 5 instantly
When touching, signal in place is sent out.Wherein, upper electrical detection adjusting screw 4 and lower electrical detection adjusting screw 5 can be adjusted,
So that the position of triggering changes, to achieve the purpose that adjust stroke.Mechanical position limitation part：Mechanical position limitation axis 10 is with work
Dynamic wallboard 6 moves up and down, when mechanical position limitation axis 10 and adjusting screw on mechanical position limitation 11 are inconsistent or with adjusted under mechanical position limitation
When screw 12 is inconsistent, then wild wall 6 cannot be further continued for moving, and reach mechanical position limitation.Wherein, spiral shell is adjusted on mechanical position limitation
Adjusting screw 12 can be adjusted under nail 11 and mechanical position limitation, so that the position of limit changes, row is adjusted to reach
The purpose of journey.It uses the double shield mode of electrical detection and mechanical position limitation, when travel switch breaks down, mechanical position limitation
Also it can play the role of safety guarantee, ensure that the safety when lifting of three rollers.
The principles and effects of the invention are only illustrated in the above embodiments, and the implementation that part uses
Example, rather than limits the present invention；It should be pointed out that for those of ordinary skill in the art, not departing from this reality
Under the premise of novel concept, various modifications and improvements can be made, these belong to the protection model of the utility model
It encloses.
