Problems solved by technology

[0002] The bucket-wheel stacker-reclaimer plays a vital role in the entire production process of the power plant. During the operation of the bucket-wheel stacker-reclaimer, it often happens that the pitching steel wire rope breaks off the top fixed pulley or causes the winding drum to be wound in disorder, especially If the loose rope cannot be found in time at night or in bad weather, it is very likely that the reverse twist will occur and the wire rope will break, and the consequences will be unimaginable
Seriously affect the stability and reliability of equipment operation, and there are major safety hazards

Embodiment 1

[0024] A bucket wheel stacker and reclaimer hoist wire rope slack protection device, which consists of: a bracket 1, a lever balance transmission mechanism 2 and a travel switch base 3, and the bracket is balanced with the lever by a nut 4 with a diameter of φ22 The transmission mechanism is connected, and the nut is welded on the top of the bracket, the upper middle position of the bracket is welded with a limit stud, and the bottom of the bracket is provided with a triangle iron brace 5 for reinforcement, and the Described support is fixed on the plane below two hoisting steel wire ropes 6, and the maximum distance of two described hoisting steel wire ropes is 1.2 meters, and described travel switch base is connected with described support.

Embodiment 2

[0026] According to the bucket-wheel stacker-reclaimer winch wire rope slack protection device described in Example 1, the material of the lever balance transmission mechanism and the support is 6-point galvanized pipe, and the lever balance transmission mechanism consists of two A transmission vertical bar 2-1 and a transmission cross bar 2-2 are welded into a U-shaped lever, and a counterweight galvanized pipe 7 is welded at the end of the transmission vertical bar.

Embodiment 3

[0028] According to the bucket wheel stacker-reclaimer hoist wire rope slack rope protection device described in embodiment 1 or 2, the limit trip post is divided into an upper limit trip post 8 and a lower limit trip post 9, and the upper limit trip post The position trip post and the lower limit trip post limit the range of motion of the lever balance transmission mechanism, wherein the upper limit trip post is slightly higher than the upper surface of the transmission vertical bar of the lever balance transmission mechanism, so The lower limit trip post is flush with the lower surface of the transmission vertical bar of the lever balance transmission mechanism.

Abstract

The invention relates to a loose rope protection device for a winch wire rope of a bucket-wheel stacker reclaimer. In the running process of the bucket-wheel stacker reclaimer, a pitching wire rope isoften detached from a top fixed pulley or a winding drum is out of order during winding; and particularly, if a loose rope is not found in time at night and in bad weather, the condition of reverse twisting likely occurs so that the wire rope is broken. The loose rope protection device for the winch wire rope of the bucket-wheel stacker reclaimer comprises a base, a support (1), a lever balanced-transmission mechanism (2) and a stroke switch base (3), wherein the support is connected with the lever balanced-transmission mechanism through a nut with the diameter being Phi22, and the nut is welded at the top of the support. A limiting stumbling column is welded at the middle upper position of the support, and an angle iron bracing piece (5) is arranged at the bottom of the support for reinforcing. The support is fixed on a plane under two winding wire ropes (6). The structure is applied to the loose rope protection device for the winch wire rope of the bucket-wheel stacker reclaimer.

Description

Technical field: [0001] The invention relates to a slack rope protection device for a steel wire rope of a hoist of a bucket wheel stacker and reclaimer. Background technique: [0002] The bucket-wheel stacker-reclaimer plays a vital role in the entire production process of the power plant. During the operation of the bucket-wheel stacker-reclaimer, it often happens that the pitching steel wire rope breaks off the top fixed pulley or causes the winding drum to be wound in disorder, especially If the slack rope cannot be found in time at night and in bad weather, it is very likely that an inverted twist will cause the wire rope to break, and the consequences will be disastrous. Seriously affect the stability and reliability of equipment operation, and there is a great potential safety hazard. Invention content: [0003] The object of the present invention is to provide a slack rope protection device for the hoist wire rope of the bucket wheel stacker reclaimer. By setting ...
