DETAILED DESCRIPTION

[0027] In the drawings of the embodiments of the present application, the same or similar reference numerals correspond to the same or similar components; in the description of the present application, it is understood that if the terms "upper", "lower", "left", "right", "inner", "outer" and the like indicate the orientation or positional relationship shown in the drawings, they are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, therefore the terms describing the positional relationship in the drawings are only used for exemplary description, and cannot be understood as a limitation on the present application, for those skilled in the art, the specific meanings of the above terms can be understood according to the specific circumstances.

[0028] As Figs. 1 to 3 shown, the present application provides a trolley running brake device, which is installed on the trolley device 40. The track device 30 includes two parallel slide rails 31, and the trolley device 40 moves along the two slide rails 31. The trolley running brake device includes at least one set of brake mechanism, and each set of brake mechanism corresponds to one of the slide rails 31.

[0029] As preferred, the brake mechanism includes two sets, and the two sets of brake mechanisms are symmetrically distributed, and each set of brake mechanism corresponds to one of the slide rails 31.

[0030] The lifting pressure assembly 10 is installed on the trolley device 40, and the two lifting pressure assemblies 10 are distributed at intervals on the trolley device 40. Preferably, the lifting pressure assembly 10 can be configured as a hydraulic cylinder mechanism.

[0031] The two lifting pressure assemblies 10 are movably connected to the two ends of the brake plate assembly 20 respectively, so that the two lifting pressure assemblies 10 can synchronously or asynchronously drive the brake plate assembly 20 to realize synchronous or asynchronous friction braking. Further, the center lines of the four lifting pressure assemblies 10 of the two sets of brake mechanisms form a rectangle to constitute a rectangular brake area, greatly improving the brake stability.

[0032] When the two lifting pressure assemblies 10 are lifted simultaneously, the brake plate assembly 20 can be planarly pressed on the slide rail 31, and the contact area is large. When the two lifting pressure assemblies 10 are lifted in sequence, the brake plate assembly 20 can be gradually pressed on the slide rail 31 from point to plane, the friction gradually increases, and the stability of the brake is improved.

[0033] The lifting pressure assembly 10 is fixedly installed on the trolley device 40, and the track device 30 is located in the lifting direction of the brake plate assembly 20. The brake mechanism is located above the track device 30, and the gravity of the trolley device 40 is used as the supporting force of the brake mechanism. The brake pressure is transmitted to the surface of the track device 30, so that the brake pressure output is realized. The overall structure is simple, and the brake debugging is convenient. The brake plate assembly 20 is abutted and supported with the track device 30, the brake pressure is adjustable, the brake area is large, and the brake distance can be quickly shortened.

[0034] In an embodiment, the lifting pressure assembly 10 and the brake plate assembly 20 are flexibly connected through the pin shaft 23 to constitute a movable connection. The brake plate assembly 20 can move relative to the lifting pressure assembly 10, so as to automatically adapt to the surface of the track device 30, and the close-fitting degree of the surface-to-surface is improved.

[0035] The flexible connection of the pin shaft 23 means that the pin shaft 23 can connect the lifting pressure assembly 10 and the brake plate assembly 20, and there is a moving space between the lifting pressure assembly 10 and the brake plate assembly 20. For example, the pin shaft 23 is provided with an elastic sleeve; or the lifting pressure assembly 10 and the brake plate assembly 20 have a matching moving space.

[0036] In an embodiment, at least one of the lifting pressure assembly 10 or the brake plate assembly 20 is provided with a long slot hole 211, and the pin shaft 23 is connected by penetrating the long slot hole 211. The long slot hole 211 is used for the movable connection of the pin shaft 23 to constitute a flexible connection.

[0037] For example, in an embodiment, the brake plate assembly 20 is provided with a transverse long slot hole 211, the pin shaft 23 is fixed to the lifting pressure assembly 10 and movably connected with the brake plate assembly 20, and the fitting timing of the brake plate assembly 20 is conveniently adjusted. Especially when the two lifting pressure assemblies 10 are lifted asynchronously, the pin shaft 23 moves in the long slot hole 211 to constitute a movable connection.

[0038] In an embodiment, the brake plate assembly 20 is provided with a longitudinal or inclined long slot hole 211, and the pin shaft 23 is fixed to the lifting pressure assembly 10 and movably connected with the brake plate assembly 20. When the lifting pressure assembly 10 is lifted asynchronously or synchronously, the pin shaft 23 moves in the longitudinal long slot hole 211, and the lifting pressure assembly 10 abuts from zero pressure to gradually increasing pressure, and gradually increases the effect of reaching the braking force.

[0039] In another embodiment, the output shaft 121 of the lifting pressure assembly 10 is provided with a long slot hole 211, which can be arranged longitudinally or transversely or obliquely to form the lifting pressure assembly 10 and movably connect with the brake plate assembly 20. When the lifting pressure assembly 10 is lifted asynchronously or synchronously, the pin shaft 23 moves in the long slot hole 211, and the lifting pressure assembly 10 gradually increases from zero pressure abutment to gradually increasing braking force.

[0040] Preferably, the lifting pressure assembly 10 adopts a hydraulic assembly, which can utilize the existing hydraulic system of the trolley device 40 to reduce the additional configuration requirements.

[0041] As shown in the drawings, Figs. 1 to 3 In an embodiment, the lifting pressure assembly 10 includes a telescopic body 12 and a mounting bracket 11 mounted on the telescopic body 12, and the mounting bracket 11 is detachably connected with the trolley device 40. The mounting bracket 11 is fixedly connected with the telescopic body 12, and the mounting bracket 11 protrudes laterally from the telescopic body 12 to form a flange structure. The telescopic body 12 is connected to the trolley device 40 through the mounting bracket 11, which not only has flexible connection, but also can flexibly adjust the mounting angle of the telescopic body 12.

[0042] In a preferred embodiment, the mounting bracket 11 is provided with an arc-shaped mounting surface 111, and at least part of the mounting surface 111 abuts against the trolley device 40. The mounting surface 111 is an outwardly convex arc-shaped curved surface, and the trolley device 40 is provided with a matching inwardly concave curved surface to form a curved surface cooperation, which can flexibly adjust the pressing angle. As a preferred, the mounting bracket 11 is mounted on the lower side surface of the trolley device 40, so that the transmission pressure between the mounting bracket 11 and the trolley device 40 is realized. The telescopic body 12 penetrates out of the trolley device 40, thereby reducing the overall installation height.

[0043] The brake plate assembly 20 is movably connected with the output shaft 121 of the telescopic body 12, wherein the brake plate assembly 20 includes a brake bracket 21 and a brake lining plate 22 fixed to the brake bracket 21. Optionally, the brake bracket 21 is a rigid structural member to maintain structural stability. The telescopic body 12 connects the brake bracket 21 to drive the brake plate assembly 20 to move up and down. The brake bracket 21 is a long strip structure, and two telescopic bodies 12 are respectively connected to the two ends of the brake bracket.

[0044] As shown in the drawings, Figs. 4 to 6 The brake lining plate 22 is a flexible structural member or a wear-resistant rigid structural member, which is used to slide and fit the track surface of the track device 30 to achieve friction braking. For example, the brake lining plate 22 is made of wear-resistant rubber, wear-resistant ceramic or other wear-resistant materials.

[0045] Further, the brake surface of the brake lining plate 22 has undulating anti-skid lines 221. The anti-skid lines 221 are formed by raised stripes or bumps. For example, the anti-skid lines 221 are configured as grid lines, wave lines or other stripe lines. The cross section of the anti-skid lines 221 can be triangular, rectangular or trapezoidal.

[0046] Optionally, the anti-skid lines 221 are configured as spherical bumps, rectangular or diamond-shaped bumps or other bump lines.

[0047] To further improve the linkage of the two sets of brake mechanisms and the stability of the brake area, the two sets of brake mechanisms are connected by the connecting rod 24, which connects the brake frames 21 to form a rectangular frame, and the brake lining plate 22 is located in the rectangular frame. The brake plate assembly 20 is connected to the telescopic main body 12. Preferably, the connecting rod 24 and the brake frame 21 are movably connected, the two brake frames 21 are linked, and the telescopic amount of any one telescopic main body 12 can be independently adjusted.

[0048] Optionally, the brake frame 21 and the connecting rod 24 are rigidly connected, and the brake frame 21 and the connecting rod 24 form a rectangular frame structure. The two telescopic main bodies 12 at the front end or the rear end of the brake frame 21 can be telescoped synchronously to press against the slide rails 31 at the same end simultaneously to achieve smooth sliding deceleration.

[0049] In an embodiment, the center distance of the lifting and pressing assembly 10 of the two sets of brake mechanisms is less than the width of the track device 30. The center distance of the telescopic main body 12 is arranged in parallel, and the interval distance between the two is less than the interval distance between the two slide rails 31, so that the pressing position of the telescopic main body 12 is close to the inner side of the track device 30, which can improve the stability of the brake and avoid the technical drawbacks of unstable braking caused by the pressing position being offset to the outside.

It is intended that the scope of the application be defined by the appended claims, rather than by the description presented above.
