Description

Technical Field

[0001] The utility model relates to the technical field of crane rail crossing, in particular to a novel rail crossing test device. Background Art

[0002] It is well known that a crane track crossing device is a device used for cranes, especially bridge cranes or gantry cranes, to ensure that they pass smoothly through track connections or track change points when running on tracks. It is usually used to ensure that the crane smoothly transitions from one track to another to avoid problems such as jamming or deviation from the track. The track crossing device plays an important role in the operational safety and efficiency of the crane, especially in large industrial sites such as factories, docks, and warehouses. Existing track crossing devices have undergone relatively mature standardized designs, but during on-site installation, various spacing errors, matching errors, and induction errors often lead to inaccurate track alignment and unsatisfactory track positioning, requiring continuous debugging and unable to be directly welded and assembled. In addition, the track crossing device is a wearing part. If it is forcibly installed without proper debugging, its service life will be greatly reduced. Utility Model Content

[0015] The technical solution of the present invention will be described below in conjunction with the drawings in the embodiments of the present invention. In the description, it should be understood that if there are terms such as "upper", "lower", "front", "rear", "left", "right" and the like indicating directions or positional relationships, they are only corresponding to the drawings of the present invention, for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific direction:

[0016] Combined with Figure 1The novel track crossing test device comprises a locking mechanism 3, a running trolley and two spaced and parallel rails 7. The running trolley comprises a frame 5 and four running wheels 8 installed on both sides of the bottom of the frame 5 and capable of being controlled by a driving motor to move and position along the two rails 7. The driving motor is generally a servo motor capable of controlling the movement of the running wheels 8 on the rails 7. A fixed rail-bearing beam 1 is provided on the outer side of one side of the two rails 7. Specifically, the fixed rail-bearing beam 1 is fixed to the top of the leg frame. A movable rail-bearing beam 6 coaxial with the fixed rail-bearing beam 1 is installed on the top surface of the frame 5 to ensure that the fixed rail-bearing beam 1 and the movable rail-bearing beam 6 can be connected in a straight line. Usually in actual application, the rail-bearing beam and the rail 7 are vertically arranged, but if the on-site space layout requires, It is also possible to set the angles between the fixed rail-bearing beam 1 and the movable rail-bearing beam 6 and the track 7 to be adjustable, so as to adapt to different test requirements. Specifically, a turntable can be installed on the top of the frame 5, and the turntable and the frame can be rotated and positioned by a latch, and the movable rail-bearing beam 6 is fixed on the turntable, so as to facilitate the adjustment of the angle between the movable rail-bearing beam 6 and the track 7, and the fixed rail-bearing beam 1 can be directly erected and fixed to the corresponding angle; the locking assembly and the latch assembly of the latch mechanism 3 are respectively installed on the same side of the beam body at the corresponding ends of the fixed rail-bearing beam 1 and the movable rail-bearing beam 6, and the latch mechanism 3 is a common mechanism of the crane track crossing device, which can automatically latch and lock the aligned fixed rail-bearing beam 1 and the movable rail-bearing beam 6, which will not be described in detail here;

[0017] The end of the movable rail-supporting beam 6 is extended outwardly from one side of the latch mechanism 3 to be connected to the limit frame plate 2, which limits the movement of the movable rail-supporting beam 6 to its position by contacting the fixed rail-supporting beam 1. The limit frame plate 2 is installed with an infrared rangefinder on the plate surface corresponding to the corresponding end of the fixed rail-supporting beam 1. The infrared rangefinder is respectively connected with the corresponding signals of the drive motor and the latch mechanism 3. The distance is measured by the infrared rangefinder, so that the running trolley can be controlled to slow down when it is about to be in place, and the latch mechanism 3 can be controlled to lock when the fixed rail-supporting beam 1 and the movable rail-supporting beam 6 are completely coaxial. According to needs, the limit frame plate 2 is installed with a contact switch on the plate surface corresponding to the corresponding end of the fixed rail-supporting beam 1, and the contact switch is set The switch is used to detect whether the distance feedback control of the infrared rangefinder is accurate and the degree of adjustment required when the limit frame 2 is in contact with the position. If, after multiple tests, it is found that accurate control cannot be achieved by relying solely on the infrared rangefinder, the contact switch is set as the primary feedback control point of the latch mechanism 3, that is, the latch can be performed by triggering the contact switch; in addition, a pressure sensor is embedded in the end beam body of the fixed rail-bearing beam 1 corresponding to the limit frame 2. The pressure sensor is set to sense the collision pressure of the limit frame 2, so that the deceleration positioning stroke of the rear-running trolley can be set in advance according to the distance, thereby reducing the damage to the structure of the latch mechanism 3 itself and the interference with the latch accuracy due to long-term collisions;

[0018] The front end of the frame 5 is detachably mounted with a wheel frame plate 4, and the wheel frame plate 4 is mounted with two horizontal wheels 9 corresponding to the two sides of any one of the rails 7 and with adjustable spacing. When the running wheels 8 of the test trolley are not well adapted to the clamping of the rails 7, generally the wheel groove width of the running wheels 8 is wider, and it is necessary to clamp the two sides of the rails 7 for positioning by means of two horizontal wheels 9, so as to facilitate accurate positioning of the rails, and to adjust the two horizontal wheels 9 according to the wheel-rail gap during actual use, so as to more closely simulate the actual operating conditions; specifically, two long holes with the same length direction can be provided on the plate surface of the wheel frame plate 4, and the wheel axles of the two horizontal wheels 9 are coaxially fixed with screws, and the screw rods pass through the corresponding long holes and are screwed with positioning nuts, and the positioning nuts are loosened, and the wheel axles of the horizontal wheels 9 are adjusted to press the long holes to move into place, and then the positioning nuts are tightened.

[0019] As needed, the two rails 7 are respectively set as a fixed rail and a movable rail close to the fixed rail beam 1 and capable of adjusting the distance between the two rails 7. The two horizontal wheels 9 are correspondingly arranged on both sides of the fixed rail, and can also adjust the distance between the two rails 7 according to test needs.

[0020] To implement the new track crossing test device described in the utility model, it is necessary to hoist the running trolley onto the two rails 7 and clamp it in place, then start the drive motor, control the running trolley to move in the direction of the fixed rail beam 1, and when the infrared rangefinder detects that the distance reaches the deceleration distance, control the running trolley to decelerate, and after detecting that the limit frame 2 is in contact with the fixed rail beam 1 in place, control the locking mechanism 3 to lock, and according to the detection results of multiple tests, adjust the positioning distance, vehicle-rail gap, control parameters and feedback timing, etc., so as to reduce errors and improve installation efficiency and rail accuracy by simulating actual working conditions.

It is obvious to those skilled in the art that the present invention is not limited to the details of the above-mentioned exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention.
