Abstract

The invention discloses a crane dynamic folding safety fence, comprising a pulley support and trolleys, wherein 8 pulleys are arranged at the periphery of the pulley support, one end of a wire cable is fixed on a first end-to-side of one trolley, the other end of the wire cable passes through the 8 pulleys, then is fixed on the forth end-to-side of another trolley, a position between the second end-to-side and the third end-to-side of the trolley is blocked by a circular tube, a support bar is arranged at the top ends of solid support pins, an upper body fence is rotatablely arranged above the support bar by articulation pieces, a safety net is arranged in the upper body fence, an LED (Light-emitting diode) display screen is arranged on the upper side wall of the upper body fence. According to the crane dynamic folding safety fence disclosed by the invention, dynamic regulation is realized, the safety net can prevent some tools or parts from falling when a crane is maintained, arc-shaped edges can avoid the occurrence of injurious condition caused by bumps of working personnel; the safety performance of the crane is greatly improved by the setting of the LED display screen.

Description

The dynamic folding safety guardrail of a kind of hoisting crane
Technical field
The present invention relates to crane facility correlative technology field, specifically the dynamic folding safety guardrail of a kind of hoisting crane.
Background technology
Hoisting crane refers to many actions elevator machinery of vertical-lift within the specific limits and horizontal carrying heavy goods.Also known as crane.Current domestic each large lifting Guangdong remy hair weight-lifting equipment Co., Ltd cancellation lift heavy driving functions gradually.The principal feature of wheel-mounted crane is: its travel operator's compartment and lifting control cabin unites two into one, be developed by crawler crane (crawler crane) to form, the crawler belt of traveling gear and mobile roof support part are become the chassis having tire, overcome the shortcoming that crawler crane (crawler crane) caterpillar block road pavement damages, belong to material carrying machine.Being arranged on the guardrail outside crane walking table, is the device shielded when maintenance, maintenance hoisting crane.But traditional hoisting crane, by place and space constraint, cannot be installed the safety barrier of the type, which results in hoisting crane and there are major safety risks, need to make improvements.
Summary of the invention
The object of the present invention is to provide the dynamic folding safety guardrail of a kind of hoisting crane, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the invention provides following technical scheme:
The dynamic folding safety guardrail of a kind of hoisting crane, comprise pulley bracket and dolly, the surrounding of described pulley bracket is provided with eight pulleys, described pulley bracket is separately fixed on the girder platform inside trolley track two ends, one end of steel cable is fixed on the first side of dolly, the other end of steel cable is fixed on the 4th side of dolly through after eight pulleys, position between described dolly second side and the 3rd side has been blocked by pipe, described dolly is provided with solid support post, the top of described solid support post is provided with support hurdle, the top on described support hurdle is rotatably provided with upper body guardrail by articulation piece, the inside of described upper body guardrail is provided with safety net, the upper side wall of described upper body guardrail is also provided with LED display.
As the further scheme of the present invention: described steel cable keeps in the same horizontal line.
As the present invention's further scheme: the two ends, left and right of described upper body guardrail are respectively arranged with arc-shaped side.
Compared with prior art, the invention has the beneficial effects as follows: the present invention is when excessive height, directly make upper body guardrail be rotated down by rotary hinge fitting and support hurdle and merge, when highly too low, directly make upper body guardrail rotate up by rotary hinge fitting, well meet wider operating needs; Can ensure that steel cable is in tensioning state all the time when dolly moves on trolley track simultaneously, and then play the effect of guard rail, not limit by place, can dynamic adjustments be realized; And the inside of described upper body guardrail is provided with safety net, when safety net can prevent hoisting crane from keeping in repair, some instruments or part falls, safety is high, and the two ends, left and right of described upper body guardrail are respectively arranged with arc-shaped side, and arc-shaped side can avoid staff collide with and cause the generation of injured situation; In addition, the upper side wall of described upper body guardrail is also provided with LED display, the operating condition that the arranging of described LED display can show hoisting crane and scroll safe poster, substantially increases the safety performance of hoisting crane.
Accompanying drawing explanation
Fig. 1 is the structural representation of the dynamic folding safety guardrail of a kind of hoisting crane.
In figure: 1-girder platform, 2-trolley track, 3-first side, 4-second side, 5-the 3rd side, 6-the 4th side, 7-pipe, 8-dolly, 9-steel cable, 10-pulley bracket, 11-solid support post, 12-pulley, 13-support hurdle, 14-articulation piece, 15-upper body guardrail, 16-arc-shaped side, 17-safety net, 18-LED read-out.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
Refer to Fig. 1, in the embodiment of the present invention, the dynamic folding safety guardrail of a kind of hoisting crane, comprise pulley bracket 10 and dolly 8, the surrounding of described pulley bracket 10 is provided with eight pulleys 12, described pulley bracket 10 is separately fixed on the girder platform 1 inside trolley track 2 two ends, pulley bracket 10 installation site can not affect the normal operation of dolly 8, one end of steel cable 9 is fixed on the first side 3 of dolly 8, the other end of steel cable 9 is fixed on the 4th side 6 of dolly 8 through after eight pulleys 12, steel cable 9 keeps in the same horizontal line, position between described dolly 8 second side 4 and the 3rd side 5 has been blocked by pipe 7, this makes it possible to ensure when dolly 8 moves on trolley track 2, steel cable 9 is in tensioning state all the time, and then play the effect of guard rail, do not limit by place, dynamic adjustments can be realized.
