Description

Technical Field

[0001] The utility model relates to the technical field of electric single-girder cranes, in particular to an anti-derailment detection device for electric single-girder cranes. Background Art

[0002] Electric single-girder crane is a kind of lifting equipment widely used in industrial and warehousing fields. It mainly consists of a beam (single beam) and an electric hoist, which can be used to transport and lift materials in factories, workshops, warehouses and other places.

[0003] The electric single-girder crane structure has a main beam, which is the main force-bearing mechanism of the crane. End beams are provided at both ends of the main beam. There is a wheel at each end of the lower part of the end beam. The edge of the wheel has a flange, which is the mechanism for the crane to move in the workshop. The two end beams at both ends are driven by their own electric motors. When one of the motors stops due to a failure, the other motor is not affected and continues to run. If the person operating the crane does not find the abnormality, the wheel under the end beam that is still running will climb onto the track and deviate from the track, causing the entire main beam to be sprained or even the entire crane to fall.

[0004] Based on the existence of the above-mentioned existing technical defects, the present application designs an anti-derail detection warning and anti-derail detection device for an electric single-girder crane to solve this existing technical defect. Utility Model Content

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] See also Figures 1 to 2 , an anti-derailment detection device for an electric single-girder crane in this embodiment includes a main beam 1, an end beam 2, an electric hoist 3 and a wheel 4.

[0030] The electric hoist 3 drives the drum to rotate through the motor, retracts and releases the wire rope on the drum to lift the object, and is equipped with a braking system and a control system for control and braking.

[0031] Both ends of the main beam 1 are integrally connected with end beams 2 and move on the track through wheels 4 assembled on the end beams 2.

[0032] Wheel 4 and end beam 2 rotate in a circular motion

[0033] The wheels 4 are equipped with drive motors to drive the wheels 4 to roll.

[0034] In this embodiment, an anti-slip detection component for sensing the movement and tilting of the end beam 2 is provided between the main beam 1 and the end beam 2 .

[0035] It should be noted that the anti-slip detection component includes a tilt sensor 5 , an audible and visual alarm 6 and a controller 7 .

[0036] The tilt sensor 5 is fixed to the end beam 2 by fastening screws, and the sound and light alarm 6 and the controller 7 are fixed to the outside of the main beam 1 by fastening screws.

[0037] The tilt sensor 5 is a photoelectric tilt sensor that measures the tilt angle through a photoelectric element. There is a light source and a photosensor inside the sensor. When the sensor is tilted, the angle at which the light emitted by the light source hits the photosensor changes. By measuring the output signal of the photosensor, the tilt angle can be calculated.

[0038] The sound and light alarm 6 is usually a speaker and an LED light, which is used to issue an alarm sound. The sound can be continuous, intermittent or changing to attract the operator's attention. The LED light emits a flashing light signal. The light signal can be different colors to convey different alarm information. After the sound and light alarm 6 control circuit receives the signal sent by the controller 7, it immediately starts the sound source and light source.

[0039] The inclination sensor 5 is installed horizontally to the end beam 2 , and both the inclination sensor 5 and the sound and light alarm 6 are electrically connected to the controller 7 .

[0040] See also Figures 3 to 4 In this embodiment, the end beam 2 is provided with a locking component that is locked to the outside of the track to prevent derailment and falling.

[0041] It should be noted that the locking component includes a limiting plug-in component and a driving return component.

[0042] Limit connector,

[0043] It includes a mounting plate 8 that is symmetrically distributed front and back on the left and right sides of the end beam 2 and is fixed by fastening screws, wherein a docking socket 10 is provided on one side of the mounting plate 8, and a reset stainless steel spring 11 is installed and fixed on the mounting plate 8 on the other side, and the other end of the reset stainless steel spring 11 is assembled and fixed with a magnetic plate 12 by fastening screws, and a limiting rod 13 is installed and fixed on the magnetic plate 12, which passes through the mounting plate 8 and is inserted into the docking socket 10.

[0044] The driving return member,

[0045] It includes a mounting frame 9 on the mounting carrier plate 8 located on one side of the reset stainless steel spring 11, which is assembled and fixed by fastening screws. A hydraulic push rod 14 is installed and fixed on the outer side of the mounting frame 9 by fastening screws. The push rod of the hydraulic push rod 14 is assembled and fixed with an electromagnet block 15 corresponding to the adsorption of the magnetic plate 12 by fastening screws.

[0046] When the electromagnet block 15 is energized to attract the magnetic plate 12 and the push rod of the hydraulic push rod 14 is in the maximum compression state, the limiting rod 13 is separated from the docking socket 10 and aligned with the surface of the other side of the mounting plate 8.

[0047] The hydraulic push rod 14 and the electromagnet block 15 are electrically connected to the controller 7 via connecting wires.

[0048] When the push rod of the hydraulic push rod 14 is in the maximum compression state, the return stainless steel spring 11 is in the maximum extension state.

[0049] When installing the equipment, ensure that the limit rod 13 is located below the track, so that the limit rod 13 can lock the track.

[0050] The working principle of the above embodiment is:

[0051] When the motor on one of the end beams 2 stops due to a fault, the motor on the other end beam 2 is not affected and continues to run, causing the end beam to move and deviate. The tilt sensor 5 is promptly sensed to sense the tilt signal of the end beam and transmits the signal to the controller 7. The controller 7 receives the signal for processing and controls the sound and light alarm 6 to sound and light alarm, so that the operator knows the fault in time and shuts down the running mechanism of the end beam 2 to prevent further tilt from causing the wheel 4 to climb onto the track and deviate from the track.

[0052] Moreover, while controlling the sound and light alarm 6 to sound and light alarm, the controller 7 synchronously controls the electromagnet block 15 to be powered off and the magnetic plate 12 to be powered off, and the reset stainless steel spring 11 elastically contracts and resets, driving the limit rod 13 to move and insert into the docking socket 10, so that the limit rod 13 cooperates with the two mounting plates 8 to be locked to the outside of the track, thereby preventing the end beam 2 from falling off the track;

[0053] In addition, after the maintenance is completed, the hydraulic push rod 14 is set to work and cooperate with the energized electromagnet block 15 to move and contact and adsorb with the magnetic plate 12. The hydraulic push rod 14 can be used to pull the upper limit rod 13 on the magnetic plate 12 back and separate from the docking socket 10, and the reset stainless steel spring 11 is compressed synchronously to prevent the limit rod 13 from blocking the end beam 2 from moving along the track, thereby effectively achieving timely warning and protection.

[0054] The electrical components mentioned in this article are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device that controls a computer, etc., and the existing public power connection technology is not described in detail in this article.
