Abstract
The utility model discloses a telescopic type car roof protection fence with a locking device. The telescopic type car roof protection fence with the locking device comprises an upper portion angle iron protection fence, wherein the upper portion angle iron protection fence is connected with two square steel slide bars. The telescopic type car roof protection fence with the locking device further comprises fixing blocks with springs, wherein the fixing blocks are arranged on the square steel slide bars, and a lower portion angle iron protection fence, wherein the lower portion angle iron protection fence is connected with sleeving bodies, and the square steel slide bars can be inserted into the sleeving bodies in a telescopic mode. The telescopic type car roof protection fence with the locking device has the advantages that when a car roof needs to be maintained, the protection fence is raised and achieves protection fence height which is ruled by a national standard, so life safety of maintenance personnel is protected; and when work is finished and an elevator is operated, the telescopic protection fence is put down and a requirement of elevator well roof height is reduced.
Description
Technical field
The utility model relates to the telescopic car top guard of a kind of elevator with latching device.
Background technology
Install in order to protect elevator, the safety that the repair and maintenance personnel operate on the sedan-chair top, regulation among the GB7588-2003 " elevator manufacturing and installation safety standard ", sedan-chair pushes up need to arrange guardrail, when the free distance of guardrail handrail outer rim level was not more than 0.85m, guardrail height should be less than 0.70m; When the free distance of guardrail handrail outer rim level during greater than 0.85m, guardrail height should be less than 1.10m.When the elevator hoistways headroom height too small, but the free distance of guardrail handrail outer rim level adopts the guardrail of 1.10m height will cause guardrail and well headroom interference during again greater than 0.85m, can't satisfy the requirement of hoistway headroom height.
The utility model content
The technical problems to be solved in the utility model provides a kind of telescopic car top guard with latching device, falls handrail when it can work as the elevator operation, guarantees elevator safety operation; When maintaining, elevator maintenance rises handrail, protection repair and maintenance personnel's life security.Efficiently solve the hoistway headroom height too small but the problem that GB arranges 1.10m height guardrail can't be installed.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions: a kind of telescopic car top guard with latching device, it comprises the guardrail body that is arranged on elevator car top top, and guardrail body top angle bar handrail is connected with the column that can stretch.In the insertion bottom body that the column that can stretch can stretch.The column lower end that can stretch is provided with square groove, and the fixed block with spring is installed, and the bottom body on also comprising bottom angle bar handrail and being fixed on the sedan-chair top is connected.Body upper end, bottom is provided with square groove, and is suitable with the fixed block with spring.
Preferably, described scalable column is two, in the insertion bottom body that can stretch.
Preferably, there is square groove described scalable column lower end, the fixed block with spring is installed, the fixed block retractable.
Preferential, there is square groove the upper end of described bottom body.
Preferably, flexible when upper armrest, when the square groove of the square groove of scalable column lower end and bottom body upper end is suitable, understand automatic spring, auto lock top guardrail with the fixed block of spring.
Compared with prior art, the utility model has the advantages that: because the top guardrail can free-extension, when sedan-chair jacking row maintenance work, can rise the top guardrail, the protection operating personal; When elevator moves, can fall the top guardrail, elevator can not collided with well headroom.Because with fixed block, when the top guardrail rose to certain altitude, fixed block can be locked guardrail by automatic spring; In the time of need to putting down the top guardrail, only need press fixed block, the top guardrail is retractable.
Description of drawings
Fig. 1 is the structural representation of a kind of telescopic car top guard with latching device of the utility model;
Fig. 2 is the schematic diagram of latching device.
The specific embodiment
Consult Fig. 1, Fig. 2 and be the embodiment of a kind of telescopic car top guard with latching device of the utility model.A kind of telescopic sedan-chair top with latching device comprises upper armrest 1, column 2, bottom handrail 3, latching device 4, body 5.Described upper armrest 1 is connected with 2 root posts 2.Column 2 bottoms have square groove, and latching device 4 is installed.Described bottom handrail 3 is connected with 2 bodies 5, and body 5 bottoms are connected with the sedan-chair top, and body 5 tops have square groove, and are suitable with the fixed block of latching device 4.Described column 2 materials are the less square steel of size, and described body 5 materials are larger-size square steel, and column 2 is free to insert in the body 5.
During use, upper armrest 1 is upwards lifted, column 2 upwards rises in body 5, when the latching device 4 in being installed in column 2 moves to the square groove on body 5 tops, fixed block in the latching device 4 is subject to the spring force effect and ejects, and column 2 is fixing, the upper armrest auto lock.After finishing using, the fixed block of latching device 4 is pressed, pressed simultaneously upper armrest 1, column 2 glides in body 5, and sedan-chair top handrail is packed up.
The utility model is not limited to embodiment discussed above.Above description to the specific embodiment is intended in order to describe and illustrate the technical scheme that the utility model relates to.Based on the apparent conversion of the utility model enlightenment or substitute and also should be considered to fall into protection domain of the present utility model.The above specific embodiment is used for disclosing best implementation method of the present utility model, so that those of ordinary skill in the art can use numerous embodiments of the present utility model and multiple alternative reaches the purpose of this utility model.
