Description

Tower machine load dolly anticreep rope device

Technical Field

The utility model relates to a building construction equipment field specifically is a tower machine load dolly anticreep rope device.

Background

The tower crane is a short for tower crane, is an indispensable hoisting equipment used in building construction, the load-carrying trolley is mounted on the tower crane, and plays the role of walking along the crane boom and hoisting heavy objects in operation, the existing tower crane load-carrying trolley is only provided with a rope-dropping prevention device above the pulley, and has no protection below the pulley, under normal condition, the steel wire rope can not be dropped from the pulley groove, but when the hook of the tower crane is in light load or no-load operation, the driver usually uses high-speed lifting in operation, sometimes, the combined actions of lifting and rotating are carried out simultaneously, under the action of inertia, the hook can swing leftwards (rightwards) under the horizontal plane of the suspension arm, the hook under the load-carrying trolley moves upwards in oblique line, when the swing amplitude is large, the angle of the steel wire rope winding into the pulley is larger than the oblique angle of the pulley groove, when the lower half-circle of the trolley pulley is not, causing the steel wire rope to be stuck, or worn or broken, thereby causing safety accidents.

SUMMERY OF THE UTILITY MODEL

Problem to above-mentioned prior art exists, the utility model aims to provide a safe and reliable's tower machine load dolly anticreep rope device can prevent effectively that wire rope from extruding the pulley groove, avoids causing the incident.

In order to achieve the above object, the utility model provides a following technical scheme:

the utility model provides a tower machine load dolly rope release preventing device, includes mounting panel and pulley, the pulley is installed at the both ends of mounting panel through the round pin axle, the first rope blocking plate of the vertical fixedly connected with in both ends of mounting panel, first rope blocking plate is located the pulley directly over, the horizontal fixedly connected with second rope blocking plate in both ends of mounting panel, second rope blocking plate is located the horizontal direction outside of pulley, the fixed rope blocking arc board that is provided with between second rope blocking plate and the mounting panel, the rope blocking arc board is located the below of pulley and coaxial with the pulley.

Preferably, the clearance between the first rope baffle, the second rope baffle, the rope baffle arc plate and the excircle of the pulley chute is 2-3 mm.

Preferably, the rope blocking arc plate is provided with a square groove in the direction of the steel wire rope to enter and exit.

Preferably, the first rope baffle, the second rope baffle, the rope baffle arc plate and the support plate are all welded.

Compared with the prior art, the beneficial effects of the utility model are that:

the utility model has the advantages of simple structure and reasonable design, safe and reliable all is provided with the rope retaining plate in the top of pulley, the horizontal outside, below, can prevent effectively that wire rope from deviating from the pulley groove, thereby avoids wire rope to block, or wearing and tearing, or the emergence of the phenomenon of fracture initiation incident.

Drawings

Fig. 1 is a schematic structural diagram of the present invention.

Fig. 2 is a sectional view taken along line a-a of fig. 1.

The labels in the figures are: 1-support plate, 2-pulley, 3-pin shaft, 4-first rope baffle, 5-second rope baffle and 6-rope baffle arc plate.

Detailed Description

For the understanding of those skilled in the art, the present invention will be described in detail with reference to the accompanying drawings and specific examples, which are not intended to limit the present invention.

Example one

Referring to fig. 1-2, a tower crane load-carrying trolley rope-dropping prevention device comprises a support plate 1, a pulley 2, a pin shaft 3, a first rope baffle 4, a second rope baffle 5 and a rope baffle arc plate 6, wherein the pulley 2 is installed at two ends of the support plate 1 through the pin shaft 3, the first rope baffle 4 is welded at two ends of the support plate 1, the first rope baffle 4 is located right above the pulley 2 and prevents a steel wire rope from dropping out of the pulley 2, the second rope baffle 5 is horizontally welded at two ends of the support plate 1, the second rope baffle 5 is located at the outer side of the pulley 2 in the horizontal direction and prevents the steel wire rope from dropping out of the pulley 2, the rope baffle arc plate 6 is welded between the second rope baffle 5 and the support plate 1 and is located below the pulley 2 and is coaxial with the pulley 2 and prevents the steel wire rope from dropping out of the pulley 2.

The first rope baffle 4, the second rope baffle 5, the rope baffle arc 6 and the excircle of the sliding groove of the pulley 2 are in a clearance of 2-3mm, and the steel wire rope is pressed in the sliding groove, so that the steel wire rope can be effectively prevented from jumping out of the sliding groove when jumping, and meanwhile, the steel wire rope in the sliding groove can be prevented from contacting and rubbing with the rope baffles when stably sliding.

Wherein, the rope blocking arc plate 6 is provided with a square groove in the steel wire rope in-out direction for the steel wire rope to go in and out of the pulley 2.

Wherein, first rope baffle 4, second rope baffle 5, keep off rope arc 6 and all adopt the welding with being connected of mounting panel 1 for whole rope release preventing device is more firm reliable.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
