Anti-creep device of track running vehicle and track crane

Abstract

The invention provides an anti-creep device of a track running vehicle, comprising an executing mechanism, a push rod and a driving rod mechanism, wherein the executing mechanism is controlled by a circuit, responds to a first control signal and a second control signal of the circuit and respectively executes a first action and a second action; the push rod is connected with the executing mechanism, extends when the executing mechanism executes the first action and retracts when the executing mechanism executes the second action; one end of the driving rod mechanism is connected with the pushrod, and the other end is provided with an anti-creep wedge block; the middle of the driving rod mechanism is articulated with a fixed pivot positioned on the track running vehicle; and the push rod is used for driving the driving rod mechanism to rotate so that the anti-creep wedge block arranged on the other end of the driving rod mechanism is matched with or separated from a running track of the track running vehicle. The invention also provides a track crane using the anti-creep device.

Description

technical field [0001] The invention relates to the field of construction machinery, and more specifically, to an anti-climbing device for rail vehicles and a rail crane. Background technique [0002] During the use of the shore-to-shore container crane, if there is a strong wind or when the cart track has a slope, sometimes the wheel brakes cannot be completely and effectively braked, and the crane's cart running mechanism stops. After running, it will crawl slowly, affecting the normal operation of the crane. The current solution is generally to manually insert wedges under the wheels to prevent the wheels from rotating, but this method not only requires two people to follow the crane on the dock, but also because it is impossible to accurately grasp the timing of wedge insertion. , It often takes many repetitions to make the crane stop accurately, which affects the loading and unloading efficiency of the crane. And the wedge block that uses at present can be pushed away...

Problems solved by technology

[0002] During the use of the shore-to-shore container crane, if there is a strong wind or when the cart track has a slope, sometimes the wheel brakes cannot be completely and effectively braked, and the crane's cart running mechanism stops. After running, it will crawl slowly, affecting the normal operation of the crane

The current solution is generally to manually insert wedges under the wheels to prevent the wheels from rotating, but this method not only requires two people to follow the crane on the dock, but also because it is impossible to accurately grasp the timing of wedge insertion. , it often takes many repetitions to make the crane stop accurately, which affects the loading and unloading efficiency of the crane

Moreover, the currently used wedges will be pushed away when the crawling force is relatively large, and cannot prevent crawling.

[0003] In the patent document with the patent application number CN00235671, a windproof device for a rail crane is provided, which is used to prevent the rail crane from moving on the rail under strong wind conditions. A wedge-shaped wedge for stopping the roller is provided outside the roller of the rail crane When the control device of the wedge-shaped wedge is always in the power-on state, the wedge-shaped wedge remains lifted from the track. After the rail crane is turned off, the control circuit of the wedge-shaped wedge is powered off, and the lifted state of the wedge-shaped wedge is released, so that the wedge-shaped wedge is in the The stopping state matched with the track, so as to prevent the movement of the track crane on the track, but when the above-mentioned windproof device is in the running state, the control circuit of the wedge wedge is always energized to keep the wedge uplifted, and the power consumption is large
