Description

An automatic detection and anti-derailment device for stacking crane

Technical Field

The utility model relates to an automatic detection and anti-derailment device for a stacker, belonging to the technical field of stackers.

Background technique

The guide wheels on the upper crossbeam of the stacker are used together with the overhead rail to ensure that the upper part of the stacker can move in the pre-set direction of the overhead rail. However, the overhead rail guide wheels only have horizontal clamping and limiting functions. If the ground is uneven or sinking, the distance between the ground and the overhead rail will increase due to the unchanged height of the stacker. Once the height exceeds the working range of the overhead rail guide wheels, the guide wheels will be separated from the overhead rail and the stacker will derail. If the stacker continues to operate at this time, there is a risk of tipping over, causing serious accidents and damage.

In addition, the existing stacker cannot automatically detect whether the stacker has derailed through the system, which poses a great safety hazard. It is difficult for safety personnel to ensure that there is no derailment accident in each stacker for 24 hours, and they cannot control the operation of the stacker immediately after it occurs. Daily maintenance requires on-site safety personnel to check and climb up the upper beam to observe whether the overhead rail guide wheel has derailed. The maintenance efficiency is low and the difficulty is high.

Summary of the invention

In view of the deficiencies in the prior art, an embodiment of the utility model provides an automatic detection and anti-derailment device for a stacker. By detecting the distance between the stacker and the overhead rail, a sensor controls a signal. When the device reaches a preset position, i.e., the derailment limit position, a system alarm is triggered after a signal is triggered, and the stacker stops running, thereby reducing the risk of derailment of the stacker.

In order to achieve the above technical objectives, the technical solution adopted by the embodiment of the utility model is:

An automatic detection and anti-derailment device for a stacker, comprising:

A guide wheel bent plate, wherein two sides of the guide wheel bent plate are each provided with a guide wheel mounting hole, and the guide wheel mounting hole is used to mount the guide wheel;

A fixing plate is installed on the guide wheel bent plate, and two linear guide rail slide rods are fixedly arranged on the fixing plate, and springs are sleeved on the linear guide rail slide rods; a vertical guide wheel bracket upper plate is arranged on the upper end of the linear guide rail slide rod, and the spring can apply an upward thrust to the vertical guide wheel bracket upper plate; a vertical guide wheel base is fixedly arranged on the upper end of the vertical guide wheel bracket upper plate, and a vertical guide wheel is arranged on the upper end of the vertical guide wheel base;

A groove-shaped photoelectric sensing plate is fixedly arranged on one side of the upper plate of the vertical guide wheel bracket, a groove-shaped photoelectric bracket is arranged on the fixed plate, a groove-shaped photoelectric bracket is arranged on the groove-shaped photoelectric bracket, and the groove-shaped photoelectric can sense the position movement of the groove-shaped photoelectric sensing plate.

Furthermore, the upper end of the linear guide rail slide rod is connected to the upper plate of the vertical guide wheel bracket through a bearing device; the bearing device includes a fixing ring and a linear bearing, and the linear bearing is fixed to the upper plate of the vertical guide wheel bracket through the fixing ring.

Furthermore, the vertical guide wheel is located between the two guide wheels.

Furthermore, when the vertical guide wheel is in a downwardly pressed state, the slot-shaped photoelectric can contact the slot-shaped photoelectric sensing board; after the vertical guide wheel is displaced upward, the slot-shaped photoelectric cannot contact the slot-shaped photoelectric sensing board.

Furthermore, the guide wheel bent plate includes a horizontally arranged upper plate portion, a vertically arranged middle plate portion and a horizontally arranged lower plate portion; the guide wheel mounting hole is arranged on the upper plate portion, and the middle portion of the upper plate portion is concave, so that the vertical guide wheel can extend upward.

The beneficial effects brought by the technical solution provided by the embodiment of the utility model are:

1. The utility model can automatically monitor in real time whether the stacker is derailed through the system, and can safely and effectively prevent the risk of derailment of the stacker before derailment.

2. Previously, stacker inspection required manual climbing up the upper beam and high-altitude operation to check whether the overhead rail guide wheel was off the overhead rail. The utility model can determine whether the stacker has derailed only through the program. It reduces the difficulty of on-site stacker safety maintenance and improves maintenance efficiency and safety.

3. The utility model has good stability, does not require frequent maintenance due to spring preloading, and is simple and easy to install.

A groove-shaped photoelectric sensing plate 7 is fixedly arranged on one side of the upper plate 5 of the vertical guide wheel bracket, a groove-shaped photoelectric bracket 8 is arranged on the fixed plate 11, and a groove-shaped photoelectric bracket 8 is arranged on the groove-shaped photoelectric bracket 8. The groove-shaped photoelectric bracket 8 can sense the position movement of the groove-shaped photoelectric sensing plate 7.

Installation process of the embodiment of the utility model: fix the vertical guide wheel 1 on the vertical guide wheel support 2, fix the vertical guide wheel support 2 on the vertical guide wheel bracket upper plate 5, and install and fix the linear bearing 4 on the vertical guide wheel bracket upper plate 5. A metal fixing plate 11 is set on the guide wheel curved plate 10, two linear guide rail slide bars 12 are welded on the fixing plate 11, and the spring 6 is placed on the linear guide rail slide bar 12. Put the vertical guide wheel bracket upper plate 5 with the linear bearing 4 into the linear guide rail slide bar 12, and finally fix it with the fixing ring 3. The groove-type photoelectric sensor plate 7 is installed on the vertical guide wheel bracket upper plate 5, and the groove-type photoelectric bracket 8 and the groove-type photoelectric 9 are installed on the fixing plate 11.

In a specific embodiment, the upper end of the linear guide rail slide bar 12 is connected to the upper plate 5 of the vertical guide wheel bracket through a bearing device; the bearing device includes a fixing ring 3 and a linear bearing 4, and the linear bearing 4 is fixed to the upper plate 5 of the vertical guide wheel bracket through the fixing ring 3. The provision of the bearing device facilitates the upper plate 5 of the vertical guide wheel bracket to move up and down.

In a specific embodiment, the vertical guide wheel 1 is located between two guide wheels.

In a specific embodiment, as shown in FIG. 3 and FIG. 4 , when the vertical guide wheel 1 is in a downwardly pressed state, the slot-shaped photoelectric sensor 9 can contact the slot-shaped photoelectric sensing plate 7 ; after the vertical guide wheel 1 moves upward, the slot-shaped photoelectric sensor 9 cannot contact the slot-shaped photoelectric sensing plate 7 .
