Description

A kind of rotary electric support

Technical field

This utility model is related to a kind of electric power support, especially a kind of rotary electric support.

Background technology

At present, a lot of road junctions are both provided with electric power support, for roads such as mounting monitor material and traffic lights Regulation and control and the equipment of feedback road conditions, because existing support is all fixedly installed, therefore when the equipment on support needs to safeguard It is necessary first to special crane to provide inspection platform for maintenance worker during maintenance, secondly need after the completion of an equipment maintenance The position of workman to be converted just can continue to complete the maintenance of next equipment, and this not only has influence on the normal operation of traffic, and Also there is very big potential safety hazard to maintenance worker so that maintenance inefficiency.

Utility model content

Technical assignment of the present utility model is for above the deficiencies in the prior art, and provides a kind of rotary electric to prop up Frame.

This utility model solves its technical problem and be employed technical scheme comprise that：A kind of rotary electric support, including Post and cross bar, wherein said pillar includes base and support arm, and the top surface of described base passes through the bottom of plane bearing and support arm Face connects, and is provided with support shaft in described plane bearing center, is provided with handle in described support arm bottom, on described support arm top Portion is provided with draw-in groove, and described cross bar is located in draw-in groove, is provided with chute in described cross bar both sides, is provided with energy and chute in described draw-in groove The slide block of cooperation, is provided with driving means in described draw-in groove bottom, when needing the equipment on support is overhauled, is pushed away by handle Dynamic support arm rotates, thus changing the position of cross bar, support shaft guarantees that support arm keeps same with base in rotation process all the time The heart, then passes through driving means to drive moving horizontally of cross bar, thus facilitating workman preferably to complete service work.

Improve further, described driving means include motor and gear, be provided with tooth bar in described cross bar bottom, described motor It is connected with described tooth bar by gear, when motor rotates, cross bar passes through the transmission of gear and tooth bar, thus driving cross bar level Mobile.

Improve further, in order to avoid in non-inspecting state, someone's malice rotational support arm, therefore in described support arm Bottom and base top be equipped with lock ring it is not necessary to during maintenance by lock with will upper and lower two lock rings pinning, thus preventing People's rotational support arm beyond maintainer.

Improve further, in order to avoid rainwater flows in plane bearing along support arm, thus affecting making of plane bearing With effect, the therefore bottom in described support arm is provided with protective jacket, and plane bearing is covered in by protective jacket well, is now placed in Lock ring on support arm is in the top of protective jacket, and the lock ring on base is located at the lower end of protective jacket.

Advantage of the present utility model：Firstly because support arm can rotate, thus can by cross bar just from road Fang Yikai, it is to avoid affect the normal operation of traffic, secondly because cross bar can move horizontally, such workman in maintenance process After the maintenance completing an equipment, only need to be by the rotation of controlled motor, you can next equipment is moved in front of oneself, Do not need workman ceaselessly to change the service work that maintenance position just can complete all equipment, greatly improve workman and safeguard Work efficiency with maintenance.

Specific embodiment

With reference to Figure of description, this utility model is described below.

As illustrated, a kind of rotary electric support, including pillar and cross bar 5, wherein said pillar includes base 1 and props up Brace 4, the top surface of described base 1 is connected with the bottom surface of support arm 4 by plane bearing 2, sets in described plane bearing 2 center There is support shaft 11, be provided with handle 3 in described support arm 4 bottom, be provided with draw-in groove 41 at described support arm 4 top, described cross bar 5 In draw-in groove 41, it is provided with chute 51 in described cross bar 5 both sides, being provided with described draw-in groove 41 can be with the slide block of chute 51 cooperation 42, it is provided with driving means in described draw-in groove 41 bottom, when needing the equipment on support is overhauled, promoted by handle 3 and prop up Brace 4 rotates, thus changing the position of cross bar 5, in rotation process, support shaft 11 guarantees that support arm 4 was rotating to support arm 4 All the time keep concentric with base 1 in journey, then pass through driving means to drive moving horizontally of cross bar 5, thus facilitating workman more Good completes service work.

Improve further, described driving means include motor 9 and gear 8, be provided with tooth bar 52, institute in described cross bar 5 bottom State motor 9 and pass through gear 8 and be connected for 52 with described tooth, when motor 9 rotates, cross bar 5 by the transmission of gear 8 and tooth bar 52, Thus driving cross bar 5 to move horizontally.

Improve further, in order to avoid in non-inspecting state, someone's malice rotational support arm 4, therefore in described support The bottom of arm 4 is equipped with lock ring 6 it is not necessary to pin with by upper and lower two lock rings 6 by lock when overhauling with the top of base 1, from And the people's rotational support arm 4 beyond preventing maintainer.

Improve further, in order to avoid rainwater flows in plane bearing 2 along support arm 4, thus affecting plane bearing 2 Using effect, the therefore bottom in described support arm 4 are provided with protective jacket 7, and plane bearing 2 is covered in by protective jacket 7 well, this When the lock ring 6 that is located on support arm 4 be in the top of protective jacket 7, the lock ring 6 on base 1 is located at the lower end of protective jacket 7.

Its operation principle is：First the lock being locked on lock ring 6 is opened during use, then promote handle 3 to drive support Arm turns 4 and moves, thus changing cross bar 5 location, then passes through the rotation of controlled motor 9 to carry moving gear 8 to rotate, because horizontal The tooth bar 52 of bar 5 bottom and gear 8 coordinate, so cross bar 5 will be driven to move horizontally by tooth bar 52 when gear 8 rotates, this Sample workman just can complete on to cross bar 5 so the repair and maintenance work of equipment in same place, greatly reduces workman's Work difficulty.

The foregoing is only embodiment of the present utility model, not thereby limit the scope of the claims of the present utility model, every The equivalent structure made using this utility model description and accompanying drawing content or equivalent flow conversion, or be directly or indirectly used in Other related technical fields, are all included in the same manner in scope of patent protection of the present utility model.
