Abstract
The utility model discloses a movable height limiter. The movable height limiter comprises a door frame, wherein the door frame consists of a cross rod, a fixed vertical rod and a rotatable vertical rod; rotatable connection is formed between the lower end of the rotatable vertical rod and a rotatable pipe base; pin type connection is formed between the lower end of the fixed vertical rod and a fixed pipe base; a positioning post, a positioning pin and a positioning hole are included in the pin type connection; the positioning post is sleeved in a pipe wall of the fixed vertical rod; the inner end of the positioning pin is connected with the positioning post; the positioning hole is L-shaped and is formed in the pipe wall of the fixed vertical rod; the outer end of the positioning pin penetrates out from the positioning hole; and the rotatable pipe base and the fixed pipe base are arranged in a foundation. The movable height limiter can play a role of safety protection in daily work and can rotate the door frame when the movable height limiter is specially required. Therefore, an ultra-high vehicle conveniently passes and the working efficiency is greatly improved.
Description
Technical field:
The utility model relates to a kind of electric equipment maintenance safeguard, particularly relates to a kind of portable height limiting device.
Background technology:
It is requisite in the safeguard procedures that height limiting device is installed in battery limits, but the height limiting device of now battery limits installation mostly is fixed, highly limits, and special car can't pass through, and practical application gets up to be subjected to certain restriction.As: when new equipment was set up in battery limits, Working vehicle needed different height, and height limiting device is because the restriction of height, can cause Working vehicle cannot get through or height limiting device is removed, and will bring inconvenience and considerable influence to carrying out of site work.
The utility model content:
Technical problem to be solved in the utility model is: overcome the deficiencies in the prior art, a kind of reasonable in design, laborsaving save time and can reusable portable height limiting device is provided.
The technical solution of the utility model is: a kind of portable height limiting device, contain door frame, described door frame is by cross bar, fixedly montant and rotation montant consist of, be that rotary type connects between described rotation montant lower end and the rotation base, described fixedly montant lower end and be between the base that fixedly bolt-type connects, described bolt-type connects and contains reference column, alignment pin and locating hole, wherein, described reference column is sleeved in the tube wall of described fixedly montant, the inner of described alignment pin is connected with described reference column, described locating hole is L shaped, be arranged on the tube wall of described fixedly montant, the outer end of described alignment pin passes from described locating hole, described rotation base and fixedly base be arranged in the ground.
The inner of described alignment pin and described reference column are threaded connection.Described rotary type connects and contains rolling bearing and bearing support.Described fixedly montant bottom is provided with handle.Described cross bar, fixing montant and rotate montant and make by tubing, and the two ends of described cross bar are provided with pipe plug.
The beneficial effects of the utility model are:
1, the utility model can play the safeguard protection effect in routine duties, can rotate door frame when the height special requirement again, and it is current to be convenient to Overheight Vehicles, has greatly improved operating efficiency.
2, the utility model adopts the bolt-type fixed structure, can fix easily and separates fixedly montant and fixedly base, in order in time open and lock door frame.
3, the utility model rotates montant and rotates between the base and is provided with rolling bearing, has improved the flexibility that door frame rotates, and has reduced labour intensity, in addition, fixedly is provided with handle on the montant, is convenient to manually carrying door frame is rotated, and is very convenient.
4, the utility model is reasonable in design, laborsaving saves time and can reuse, and it is applied widely, is easy to promotion and implementation, has good economic benefit.
Description of drawings:
Fig. 1 is the structural representation of portable height limiting device;
Fig. 2 is connected structure enlarged drawing shown in Figure 1.
The specific embodiment:
Embodiment: referring to Fig. 1 and Fig. 2, among the figure, 1-is base fixedly, the 2-alignment pin, and the 3-locating hole, the 4-handle, 5-is montant fixedly, and 6-rotates montant, and 7-rotates base, 8-reference column.
Portable height limiting device contains door frame, door frame is by cross bar, fixedly montant 5 and rotation montant 6 consist of, wherein: rotating between montant 6 lower ends and the rotation base 7 is that rotary type connects, fixing montant 5 lower ends and be between the base 1 that fixedly bolt-type connects, bolt-type connects and contains reference column 8, alignment pin 2 and locating hole 3, reference column 8 is sleeved in the tube wall of fixing montant 5, the inner of alignment pin 2 is connected with reference column 8, locating hole 3 is L shaped, be arranged on the tube wall of fixing montant 5, the outer end of alignment pin 2 passes from locating hole 3, rotate base 7 and fixedly base 1 be arranged in the ground.
The inner of alignment pin 2 and reference column 8 are threaded connection, and are convenient to dismounting.Rotary type connects and contains rolling bearing and bearing support, can certainly adopt rotating shaft and axle sleeve type structure.Fixedly montant 5 bottoms are provided with handle 4, and being convenient to manually mention fixedly, montant 5 rotates.Cross bar, fixing montant 5 and rotate montant 6 and make by tubing, and the two ends of cross bar are provided with pipe plug.
Without Overheight Vehicles by the time, reference column 8 is sleeved on simultaneously fixing montant 5 and fixedly in the inner chamber of base 1, plays preventing the fixedly purpose of montant 5 rotations.When having the vehicle of special height to pass through, mention alignment pin 2, be located at the upper end of locating hole 3, at this moment, alignment pin 2 drives reference column 8 and breaks away from from rotate base 1, then, manually mention handle 4, to road one side shifting, rotate montant 6 and rotate around rotating base 7, door frame namely can be rotated to a side of road, and Overheight Vehicles are passed through.By complete, oppositely mobile fixedly montant 5 makes it again be positioned at the fixedly top of base 1, mention alignment pin 2, be located at the lower end of locating hole 3, reference column 8 is sleeved on again fixing montant 5 and fixedly in the inner chamber of base 1 simultaneously, prevent that fixedly montant 5 rotates, finish a circulation.
