Description

Special fixing device for vertical cable of tower crane

Technical Field

The utility model relates to a construction technical field, in particular to an auxiliary device for on tower crane specifically is a special fixing device of vertical cable conductor of tower crane.

Background

The tower crane is as aerial working equipment, and the cable conductor can be along with the altitude mixture increase and longer, if not fixed with the tower crane fuselage, is in easily under the free suspension state for a long time and tower crane standard festival friction scratch broken skin, can cause the tower crane electrified, takes place the electric shock accident. Through visiting and observing, we find that most cables all adopt simple fixing measures. The common method is that a section of horizontal square steel is welded on a tower crane section, an insulating porcelain insulator is attached, and a cable is fixed on the porcelain insulator through a binding belt. This method has the following disadvantages: firstly, the fixing mode of binding the porcelain bottle by using the binding belt is not firm, and the binding belt is easy to age and stretch off; secondly adopt the welded mode with the fixed of tower crane festival to tower crane steel construction itself be a destruction, have uncertain influence to the tower crane bearing, the high altitude welding operation is inconvenient in addition, and it is unfavorable for reuse at last, and the component just can be taken off from the tower crane after burning off the square steel, and the scar that leaves on the tower crane is difficult to get rid of, and whole image is relatively poor, has just left the potential safety hazard in the installation next time.

Disclosure of Invention

The utility model aims at solving the problems existing in the prior art and providing a special fixing device for the vertical cable of the tower crane.

The utility model discloses a realize through following technical scheme:

a special fixing device for a vertical cable of a tower crane comprises a fixing plate which is vertically arranged, wherein the upper part and the lower part of the fixing plate can be detachably connected with a U-shaped hoop, and the main body of the U-shaped hoop is positioned on one side of the inner side of the fixing plate; the detachable support otic placode of installing a pair of vertical setting on the outside face of fixed plate, the position that is close to the fixed plate between the support otic placode installs the insulator, and the interior insulation wheel is installed to the position that is located the insulator below, and the position that is located the interior insulation wheel outside installs the outer insulation wheel. The fixed plate is used for fixing on the tower crane as the carrier, and the U-shaped hoop can realize that the installation between fixed plate and the tower crane is fixed, supports otic placode, insulating vase, interior insulating wheel, outer insulating wheel and is used for blocking and put and protect the cable conductor

As a preferred technical scheme, the mounting mode between the outer insulation wheel and the supporting lug plate is as follows: the supporting ear plate is provided with an inclined sliding groove which inclines from the outer side to the inner side, and the outer insulating wheel is slidably clamped in the inclined sliding groove through rotating shafts at two ends of the outer insulating wheel. The outer insulating wheel is designed to have the following functions: when the cable conductor rebound, can drive the outer insulating wheel and slide to the slant along the slant spout of slope, the removal of cable conductor does not receive any influence, and after the cable conductor removes, the insulating wheel will fall back the normal position along the slant spout of slope, makes the inner and outer insulating wheel press from both sides the cable conductor tightly simultaneously under the effect of cable conductor dead weight, finally plays the fixed effect of cable conductor.

As the preferred technical scheme, the inner plate surfaces on two opposite sides of the supporting lug plate are provided with insulating rubber pads. After the insulating rubber pad is arranged on the supporting lug plate, the area (the area surrounded by the supporting lug plate, the insulating porcelain bottle and the inner and outer insulating wheels) of the vertical movement of the cable becomes a closed insulating ring, so that the charged body is insulated again

As a preferable technical scheme, the two side plate edges of the fixing plate are bent towards the inner side to form a protective edge. After the safe edge is arranged, the structure of the fixing plate is more reasonable, the fixing plate is easier to fix on a standard section of a tower crane, and the fixing is firmer and safer.

As the preferred technical scheme, the supporting lug plate consists of two L-shaped plates, and the narrow side plates of the L-shaped plates are detachably connected with the fixing plate through bolts.

The utility model discloses device design science, it is ordinary with the material, the structure is succinct, and the preparation is convenient, and simple to use can reduce the cost of labor and reduce the material extravagant, can effectively solve the unable effectively fixed problem of cable conductor of current tower crane. The device's use can improve the security and the effectual protection cable of construction to form automatic unclamping and closure in tower crane jacking in-process, realize automaticly. The device can be quickly installed and dismantled, can be recycled, and increases the turnover frequency. The design and the use of the device meet the aim of 'four sections one by one environmental protection' of green construction advocated by the nation, and are worth popularizing and using.
