Description

TECHNICAL FIELDThe present invention relates to the technical field of vehicle stopping of transport devices, in particular to a vehicle stopping device for dock transport devices.PRIOR ARTWith the rapid economic development, the cargo capacity on the dock cannot meet the actual demand, therefore it is necessary to re-implement transport devices such as ship unloaders. Safety in the conversion of transport equipment such as ship unloaders is very important. The usual solution consists in arranging a vehicle stop, wherein the position of the vehicle stop can be adjusted as desired.The vehicle stops of existing ship unloaders are generally fixed, permanent vehicle stops, so there are relatively few temporary vehicle stops whose position can be arbitrarily adjusted. Among them, the structure disclosed in Chinese Patent Application (CN 208615962 U) is most representative (as illustrated in FIG. 1 ). The base of the vehicle stop device is installed with two connecting blocks, with a through slot being arranged at the lower end of each connecting block for engaging on the railway rail. Rollers are arranged on the through slots for moving the vehicle stop. However, since the connection between the vehicle stopper and the through slot is movable, the stability against slipping and tilting of the vehicle stopper is limited or cannot achieve the function of blocking large transport equipment such as ship unloaders, which greatly restricts the use of the vehicle stopper.CONTENT OF THE PRESENT INVENTIONIn view of this, the present invention provides a vehicle stopping device for dock transportation apparatuses. It is distinguished by simple and convenient dismantling and assembly and any desired position setting. The structure has good stress, which has good stability against slipping and tipping.For the present invention, the above problems are solved by the following technical means:A vehicular stopper device for dock transportation equipment according to the present invention, the device comprising a steel support plate fixed to the lower end of the steel rail, two sets of support plates disposed parallel to both sides of the steel rail and vertically fixed to the steel support plate, a trapezoidal vehicular stopper steel frame having a vertical front surface fixed to the upper ends of two sets of support plates, and a buffer block fixed to the front surface of the vehicular stopper steel frame.Preferably, the trapezoidal vehicle-abutting steel frame comprises a trapezoidal frame combined and fixed by an upper plate, a lower plate, a stand plate and a rear slant plate, a web plate disposed at the center of the trapezoidal frame and fixedly connected to the vertical center line of the trapezoidal frame, and a waist plate for connecting the stand plate and the central part of the rear slant plate and disposed parallel to the upper plate and the lower plate, the waist plate being divided into a left portion and a right portion by the web plate, the buffer block being fixed at the upper center of the stand plate.It is preferably provided that furthermore between the stand plate and the rear inclined plate one or more stiffening plates arranged parallel to the upper plate and the lower plate are arranged.Preferably, it is provided that the buffer block is fixedly installed by means of connecting bolts, wherein the upper part of the connecting bolt is countersunk in the surface of the buffer block and is inserted by 2-3 cm.Preferably, it is arranged that the two sets of support plates are supported evenly at positions on both sides of the lower part of the vehicle abutting steel frame, the four corner points of the lower part of the vehicle abutting steel frame being connected to the support plate, respectively.Preferably, it is provided that the support plate is 3-5 cm higher than the steel rail.From the above technical solutions, it is apparent that the present invention has the following advantageous effects:For the vehicle stopper device for dock transportation equipment according to the present invention, the steel plate is welded and fixed into a trapezoidal vehicle stopper steel frame and welded and fixed to the steel support plate of the steel rail as a whole so as to be fixed to the high-pile dock directly above the steel rail as a temporary vehicle stopper for the ship unloader. The ship unloader is prevented from crossing the end of the rail to protect the ship unloader and buffer the impact force of the ship unloader. The vehicle stopping device for dock transportation apparatuses according to the present invention has advantages of being simple in manufacture and low in processing cost. The overall structure is a trapezoidal combination structure with good stress and good stability against slipping and tipping, whereby the operation of large transport devices such as ship unloaders can be effectively blocked. The vehicle stop is installed or removed by means of a welding machine or a cutting support plate, so that the installation position can be set arbitrarily, which is suitable for temporary blocking and safety devices for equipment running on steel rails under various environmental conditions. Installation and removal are simple and convenient, thereby reducing operator workload and improving operator work efficiency.BRIEF DESCRIPTION OF THE DRAWINGSFIG. 1 is a schematic diagram showing the structure of an existing vehicle stopping device, FIG. 2 is a schematic view showing the structure of a vehicle stopping device for dock transportation equipment according to the present invention; FIG. 3 is a sectional view of A-A in FIG. 2.Reference numerals as shown in FIGS. 2 and 3 : dock platform-1, steel rail-2, steel support plate-3, support plate-4, vehicle stop steel frame-5, upper plate-51, lower plate-52, stand plate-53, rear swash plate-54, web plate-55, waist plate-56, stiffening plate-57, buffer block-6, connecting bolt-7.DETAILED DESCRIPTIONIn describing the present utility model, it is to be understood that the orientation or positional relationships indicated by the terms center, above, below, front, rear, left, right, vertical, horizontal, above, below, inside, outside, etc. are based on the orientation or positional relationships illustrated in the drawing.

The ship unloader is prevented from crossing the end of the rail to protect the ship unloader and buffer the impact force of the ship unloader. The vehicle stopping device for dock transportation apparatuses according to the present invention has advantages of being simple in manufacture and low in processing cost. The overall structure is a trapezoidal combination structure with good stress and good stability against slipping and tipping, whereby the operation of large transport devices such as ship unloaders can be effectively blocked. The vehicle stop is installed or removed by means of a welding machine or a cutting support plate 4 so that the installation position can be set arbitrarily, which is suitable for temporary blocking and safety devices for equipment running on steel rails 2 under various environmental conditions. Installation and removal are simple and convenient, thereby reducing operator workload and improving operator work efficiency.During installation, the steel support plate 3 and the steel rail 2 are first inserted into the rail channel of the dock platform 1. The lower side of the support plate 4 is then fixed to the lower side of the steel rail 2 by full welding with the steel support plate 3. Then, the vehicle abutting steel frame 5 installed with the buffer block 6 is lifted to the specified installation position by a crane. It is ensured that the vehicle abutting steel frame 5 is lowered after the vertical center line of the vehicle abutting steel frame 5 is aligned with the center line of the steel rail 2. Finally, the lower surface of the vehicle stop steel frame 5 is welded to the upper surface of the support plate 4, whereby the vehicle stop device for dock transportation apparatuses according to the present embodiment is fixed to the steel rail 2. At the time of removal, only the support plate 4 on the lower side is cut off by means of a gas cutter, thereby separating the vehicle abutting steel frame 5 from the steel supporting plate 3. The backing plate 4 remaining on the steel support plate 3 is then removed by gas cutting. The vehicle stop device may be moved to the next position for installation after removal and may also be used for permanent vehicle stop.As a preferred embodiment of the above-described technical solution, it is arranged that the trapezoidal vehicle-abutting steel frame 5 comprises a trapezoidal frame combined and fixed to each other by an upper plate 51, a lower plate 52, a stand plate 53 and a rear slant plate 54, a web plate 55 disposed at the center of the trapezoidal frame and fixedly connected to the vertical center line of the trapezoidal frame, and a waist plate 56 for connecting the stand plate 53 and the central part of the rear slant plate 54 disposed parallel to the upper plate 51 and the lower plate 52, the waist plate 56 being divided into a left portion and a right portion by the web plate 55, the buffer block 6 being fixed to the upper center of the stand plate 53. By welding the upper plate 51, the lower plate 52, the stand plate 53 and the rear slant plate 54, they are assembled into a trapezoidal frame. The web plate 55 is again used to reinforce the limitation in the center line. In conjunction with the joint support of the waist plate 56, the entire vehicle-abutting steel frame 5 has excellent strength of resistance, support strength and long life.As a further improvement of the above-described technical solution, it is provided that one or more reinforcing plates 57 arranged in parallel with the upper plate 51 and the lower plate 52 are further arranged between the stand plate 53 and the rear slant plate 54 to further increase the strength of the vehicle abutting steel frame 5.As a further improvement of the technical solution described above, it is provided that the buffer block 6 is fixedly installed by means of connecting bolts 7, the upper part of the connecting bolt 7 being countersunk in the surface of the buffer block 6 and inserted by 2-3 cm, so that a direct impact of the ship unloader with the connecting bolt 7 is avoided to fully exert the buffering action of the buffer block 6.As a preferred embodiment of the above-described technical solution, it is arranged that the two sets of support plates 4 are supported uniformly at positions on both sides of the lower part of the vehicle abutting steel frame 5, the four corner points of the lower part of the vehicle abutting steel frame 5 are respectively connected to the support plate 4, so that the attachment welding of the vehicle abutting steel frame 5 is facilitated to improve the attachment strength and flatness.As a preferred embodiment of the technical solution described above, it is provided that the support plate 4 is 3-5 cm higher than the steel rail 2 in order to avoid damage to the steel rail 2.Finally, it is to be noted that the above embodiments are used only to illustrate and not limit the technical solutions of the present invention although the present invention will be described in detail with reference to the preferred embodiments.
