Abstract

The utility model relates to a parachute gear of a bridge type scaffold bridge frame. A square lever shaft is arranged on a rectangular frame. The square lever shaft is connected with two inwards bent gripper arms by two pin rolls. The middle parts of two gripper arms are connected with a tension spring. The inner sides of two gripper arms are respectively provided with a trolley which is connected with a connecting rod, the other end of which is connected with the pin rolls of the square lever shaft. The centers of two trolleys are provided with holes. Two steel cables respectively pass through the central holes of two trolleys. The lower ends of two steel cables are respectively connected with cable nodes at two sides of the lower part of the frame. The upper ends of two steel cables are combined as one strand to connect the branch line of a cord used for suspending the bridge frame. Due to the action of the gravity of the bridge frame, two steel cables ensure that two gripper arms conquer the traction force of the tension spring to be separated towards two sides by two trolleys, the bridge frame rises and descends up and down freely; once the rope suspending the bridge frame breaks, the trolleys at the inner sides of two gripper arms lose outward tension, and the tension spring between two gripper arms is brought into play, thereby ensuring that two gripper arms enclasp towards an upright post to avoid the bridge frame falling.

Description

The parachute gear of bridge scaffold crane span structure
Affiliated technical field
The utility model relates to the parachute gear of bridge scaffold crane span structure.
Background technology
Bridge scaffold comprises the crane span structure between two columns and the column.The lifting of crane span structure can adopt elevator or hoist engine to carry out lifting with lifting rope.Because the lifting rope fracture, whole crane span structure will be thrown, and causes holy terror's body casualty accident.
The utility model content
The purpose of this utility model is the parachute gear that the bridge scaffold crane span structure is provided in order to address the above problem, even the lifting rope fracture, whole crane span structure will can not thrown, and avoid the generation of human casualty accident.
The technical scheme that its technical problem that solves the utility model adopts is: the two-end part at the crane span structure adjacent with column is connected the utility model device.The utility model device is a cuboid framework, and axle bed is housed on framework, connects a square bar axle on axle bed, and there is screw thread the end of square bar axle, is connected on the framework with nut.Connect two aduncate chelas of symmetry with two bearing pins on the square bar axle, two chelas open and stretch out the outside of column.Be connected with an extension spring at the middle part of two chelas, two chelas are inwardly strained.In the inboard of two chelas a roller is arranged respectively, roller is connected with connecting rod, and the other end of connecting rod is connected with the bearing pin of square bar axle.Center at two rollers is porose, two wire rope pass from the centre bore of two rollers respectively, the lower end of two wire rope is connected to the knot point of the both sides, bottom of framework, after one is synthesized in the upper end of two wire rope, is connected with the branch line of the rope that hangs crane span structure.Because the effect of crane span structure gravity, two wire rope separate towards both sides by the pulling force that two rollers make two chelas overcome extension spring, make two chelas be positioned at the both sides of column, the free oscilaltion of crane span structure; Disconnect in case hang the rope of crane span structure, the roller of two chela inboards loses outside tension force, and the extension spring between two chelas is had an effect, and two chelas are held tightly to column, avoids falling of crane span structure.On the framework in two chela outsides, banking pin is arranged, prevent that two chelas from too outwards opening.
Effective effect of the present utility model is, uses the parachute gear of bridge scaffold crane span structure of the present utility model, even the lifting rope fracture, whole crane span structure will can not thrown, and avoid the generation of human casualty accident.
Description of drawings
Fig. 1 is the structural representation of the parachute gear of bridge scaffold crane span structure of the present utility model.1-column among the figure, 2-chela, 3-framework, 4-square bar axle, 5-axle bed, 6-bearing pin, 7-connecting rod, 8-roller, 9-extension spring, 10-banking pin.
Fig. 2 is the A-A view of Fig. 1.2-chela among the figure, 3-framework, 4-square bar axle, 5-axle bed, 6--bearing pin, 8--roller, 11--wire rope, 12--knot point.
The specific embodiment
Two-end part at the crane span structure adjacent with column (1) is connected the utility model device.The utility model device is a cuboid framework (3), and cuboid framework (3) is 60 * 80 * 30 centimetres.Axle bed (5) is housed on framework (3), goes up a connection square bar axle (4) at axle bed (5), there is screw thread the end of square bar axle (4), is connected on the framework (3) with nut.Go up with two bearing pins (6) connection, two aduncate chelas of symmetry (2) at square bar axle (4), two chelas (2) open and stretch out the outside of column (1).Be connected with an extension spring (9) at the middle part of two chelas (2), make inwardly tension of two chelas (2).In the inboard of two chelas (2) roller (8) is arranged respectively, roller (8) is connected with connecting rod (7), and the bearing pin (6) of the other end of connecting rod (7) and square bar axle (4) is connected.Center at two rollers (8) is porose, two wire rope (11) pass from the centre bore of two rollers (8) respectively, the lower end of two wire rope (11) is connected to the knot point (12) of the both sides, bottom of framework, after one is synthesized in the upper end of two wire rope (11), be connected with the branch line of the rope that hangs crane span structure.Because the effect of crane span structure gravity, two wire rope (11) separate towards both sides by the pulling force that two rollers (8) make two chelas (2) overcome extension spring (9), make two chelas (2) be positioned at the both sides of column (1), the free oscilaltion of crane span structure; Disconnect in case hang the rope of crane span structure, the inboard roller (8) of two chelas (2) loses outside tension force, and the extension spring (9) between two chelas (2) is had an effect, and two chelas (2) are held tightly to column (1), avoids falling of crane span structure.On the framework (3) in two chelas (2) outside, banking pin (10) is arranged, prevent that two chelas (2) from too outwards opening.
