Abstract
The utility model discloses an anti-rope-breaking device of an inverted-triangular arm support trolley, which comprises a pipe body, a shaft hole, a lifting lug, a balancing weight and a stop bolt, wherein the balancing weight is positioned at the bottom of the pipe body and is fixedly connected with the pipe body, the shaft hole is a through hole and is positioned in the middle of the pipe body, and the pipe body can rotate relative to the pin shaft by penetrating through the shaft hole and being fixedly connected with the trolley through the pin shaft. The lifting lug is positioned on one side of the pipe body and is used for penetrating the traction rope. The stop bolt is positioned at the upper part of the pipe body, is vertical to the pipe body and is used for contacting with a web member of the inverted triangle arm support so as to stop the trolley. The device has simple structure, convenient installation and easy realization of locking.
Description
Technical Field
The utility model relates to the technical field of tower cranes, in particular to a rope breakage preventing device for a reverse triangular arm support trolley.
Background
Flat-head tower crane load dolly becomes width of cloth motion in-process on the jack-up, and the haulage rope takes place the fracture suddenly, and the dolly moves ahead out of control under the gravity and the inertial action of hoisting weight, and the hoisting weight descends rapidly, very easily causes dangerous accident, therefore the load dolly need possess one kind and prevent disconnected rope protection device, prevents that the dolly from moving ahead out of control.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a rope breakage preventing device for a reverse triangular arm support trolley, which can prevent the trolley from moving forward out of control under the action of gravity and inertia of a hoist weight to prevent danger when a traction rope is suddenly broken when a load-carrying trolley runs.
In order to achieve the purpose, the anti-rope-breaking device for the inverted triangular arm support trolley comprises a pipe body, a shaft hole, a lifting lug, a balancing weight and a stop bolt, wherein the balancing weight is positioned at the bottom of the pipe body and fixedly connected with the pipe body; the lifting lug is positioned on one side of the pipe body and is used for penetrating through a traction rope; the stop bolt is positioned at the upper part of the pipe body, is vertical to the pipe body and is used for contacting with a web member of the inverted triangle arm support so as to stop the trolley.
Further, the pipe body is a square pipe or a round pipe.
The utility model has the beneficial effects that: the rope breakage preventing device is simple in overall structural form, convenient to produce and process and easy to realize;
the installation and the use are convenient, the connection with the trolley is realized through the pin holes, the operation is easy, and the time and the labor are saved.

FIG. 2 is a schematic view of the present invention mounted on a cart;
in the figure, 1-pipe body, 2-shaft hole, 3-lifting lug, 4-balancing weight and 5-stop bolt.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples.
As shown in fig. 1, the rope breakage preventing device for the inverted triangular arm support trolley comprises a pipe body 1, a shaft hole 2, a lifting lug 3, a balancing weight 4 and a stop bolt 5, wherein the balancing weight 4 is located at the bottom of the pipe body 1 and fixedly connected with the pipe body 1, the shaft hole 2 is a through hole and located in the middle of the pipe body 1, and a pin shaft penetrates through the shaft hole 2 and is fixedly connected with the trolley, so that the pipe body 1 can rotate relative to the pin shaft. The lifting lug 3 is positioned at one side of the pipe body 1 and is used for penetrating a traction rope. The stop bolt 5 is positioned at the upper part of the pipe body 1, is vertical to the pipe body 1 and is used for contacting with a web member of the inverted triangle arm support so as to stop the trolley. The pipe body 1 is a square pipe or a round pipe. When the trolley does amplitude variation motion forwards, a front traction rope is tensioned to lift the front rope breaking prevention device, namely a balancing weight 4 is lifted, a stop bolt 5 on the front rope breaking prevention device is far away from a web member of an inverted triangular arm support, and the trolley moves forwards under the traction of an amplitude variation mechanism on the arm support. Similarly, when the trolley makes amplitude variation movement backwards, the rear traction rope is tensioned to lift the rear anti-rope breaking device, the movable bolt 5 is arranged on the rear anti-rope breaking device and is far away from the inverted triangle arm support web member, and the trolley moves backwards on the arm support under the traction of the amplitude variation mechanism.
Under abnormal conditions, when the trolley moves forwards in a variable amplitude manner, the front traction rope is disconnected, the front rope breakage prevention device is separated from the constraint of the traction rope, rotates around the trolley connecting pin shaft under the action of the balancing weight 4, the stop bolt 5 extends into a gap between the web members of the inverted triangular arm support, and when the stop bolt 5 is in contact with the web members, the web members prevent the stop bolt 5 from continuing to move, so that the trolley is prevented from moving forwards out of control, as shown in fig. 2. Similarly, when the trolley makes amplitude variation movement backwards, the rear traction rope is disconnected, and the movable bolt 5 is arranged on the rear anti-breakage rope device to play a role. The rope breaking prevention device is simple in structure, convenient to operate and obvious in stopping effect.
The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited thereto, and various changes which can be made within the knowledge of those skilled in the art without departing from the gist of the present invention are within the scope of the claims of the present invention.
