Detailed Implementation
[0022] The present invention will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be emphasized that the following description is merely exemplary and not intended to limit the scope and application of the present invention.
[0023] like Figures 1-4 As shown, this embodiment provides a suspended truss device for loading arms. The device includes a frame, which includes a crossbeam 1 and a loading arm connector 2. The crossbeam 1 is a frame structure composed of a Y-axis track frame 11, an X-axis track frame 12, and a moving trolley 13. The frame structure can significantly reduce the overall weight of the frame, achieving a lightweight design. One end of the loading arm connector 2 is connected to the moving trolley 13, and the other end is connected to the conventional loading arm to be moved. The moving trolley 13 can move relative to the X-axis track frame 12 or the Y-axis track frame 11, thereby driving the loading arm to move and align. It is understood that the crossbeam 1 should also include a drive unit, which can drive the corresponding structure to move stably, thereby enabling the moving trolley 13 to move relative to the X-axis track frame 12 or the Y-axis track frame 11.
[0024] The upper end of the crossbeam frame 1 is provided with a connecting plate 3, which can be connected to the trestle bridge to suspend the crossbeam frame 1 in the air. That is, the crossbeam frame 1 is screwed to the bottom of the trestle bridge through the connecting plate 3, and the loading arm is suspended above the tanker through the crossbeam frame 1.
[0025] In use, the loading arm is fixed below the loading arm connector 2. Then, as needed, the moving trolley 13 moves relative to the X-axis track frame 12 or the Y-axis track frame 11, thereby moving the loading arm until alignment is completed. It can be seen that this solution achieves the purpose of automatic movement and alignment of ordinary loading arms by designing this suspended truss device. That is, by combining ordinary loading arms with this suspended truss device, a compact, stable, and low-cost automatic moving loading arm is formed, which solves the shortcomings of the existing use of ordinary loading arms.
[0026] The Y-axis track frame 11 is the outer frame of the crossbeam frame 1. The Y-axis track frame 11 includes at least a first Y-axis track rod 111 and a second Y-axis track rod 112. The first Y-axis track rod 111 and the second Y-axis track rod 112 are arranged side-by-side, and the distance between the first Y-axis track rod 111 and the second Y-axis track rod 112 is adapted to the length of the X-axis track frame 12. That is, the X-axis track frame 12 is located within the frame formed by the first Y-axis track rod 111 and the second Y-axis track rod 112. It is understood that the first Y-axis track rod 111 and the second Y-axis track rod 112 can be fixed by connecting to the X-axis track frame 12, or they can be fixed by additional connecting rods. This embodiment preferably uses the latter, that is, the Y-axis... The track frame 11 also includes a third Y-axis track rod 113 and a fourth Y-axis track rod 114. The third Y-axis track rod 113 and the fourth Y-axis track rod 114 are respectively disposed at both ends of the first Y-axis track rod 111 and the second Y-axis track rod 112 and form a "U"-shaped frame, which can increase the stability of the structure. A drive mechanism is provided at the lower end of the first Y-axis track rod 111 and the second Y-axis track rod 112, respectively. The drive mechanism is connected to the X-axis track frame 12 to drive the X-axis track frame 12 to move relative to the Y-axis track frame 11. That is, in this embodiment, a drive mechanism is provided on the Y-axis track frame 11. The drive mechanism is connected to the X-axis track frame 12 and can drive the X-axis track frame 12 to move relative to the Y-axis track frame 11.
[0027] The drive mechanism includes a lead screw 115, a lead screw bearing housing 116, and a drive motor 117. The lead screw bearing housing 116 is installed below the ends of the first Y-axis track rod 111 and the second Y-axis track rod 112. Both ends of the lead screw 115 are connected to the lead screw bearing housing 116, and one end of the lead screw 115 extends and is connected to the drive motor 117 via a coupling 110. Simultaneously, a sliding block 118 is provided on the lead screw 115, which is connected to two linear bearings in a cross-shaped configuration. It is then connected to the X-axis track frame 12, which improves the stability of the X-axis track frame 12 during operation. In this embodiment, the drive motor 117 is preferably an RV reduction motor 132, and the sliding block 118 is a lead screw nut. The drive motor 117 drives the lead screw 115 to rotate relative to the lead screw bearing seat 116. At the same time, the sliding block 118 will move relative to the lead screw 115, thereby driving the X-axis track frame 12 to move relative to the Y-axis track frame 11. It can be understood that, if necessary, the drive mechanism can also be a telescopic push rod and a transmission chain, etc.
[0028] The inner sides of the first Y-axis track rod 111 and the second Y-axis track rod 112 are provided with a Y-axis moving track 119. In this embodiment, the Y-axis moving track 119 is preferably groove-shaped. At the same time, the X-axis track frame 12 is provided with a traveling wheel 125 that is adapted to the Y-axis moving track 119. The traveling wheel 125 is fitted into the Y-axis moving track 119, which on the one hand provides support for the X-axis track frame 12, and on the other hand reduces the moving resistance, ensuring that the X-axis track frame 12 moves smoothly relative to the Y-axis track frame 11.
[0029] The X-axis track frame 12 includes a first X-axis track rod 121, a second X-axis track rod 122, and an intermediate connecting plate 123. The first X-axis track rod 121 and the second X-axis track rod 122 are arranged side by side and extend along the length of the Y-axis track frame 11. The intermediate connecting plate 123 is located at both ends of the first X-axis track rod 121 and the second X-axis track rod 122, forming a closed-loop inner frame. The intermediate connecting plate 123 is connected to a sliding block 118 on the drive mechanism, and the traveling wheels 125 are located on the outside of the intermediate connecting plate 123. The drive mechanism drives the intermediate connecting plate 123 and the inner frame formed by it, the first X-axis track rod 121, and the second X-axis track rod 122 to move relative to the Y-axis track frame 11 via the sliding block 118. The moving trolley 13 is located on the first X-axis track rod 121 and the second X-axis track rod 122. The X-axis track rods 122 are positioned relative to the first X-axis track rod 121 and the second X-axis track rod 122. Simultaneously, the trolley 13 can move synchronously with the first X-axis track rod 121 and the second X-axis track rod 122. In use, the movement of the trolley 13 relative to the first X-axis track rod 121 and the second X-axis track rod 122 will cause the loading arm to move in the X-axis direction, thereby achieving alignment adjustment of the loading arm in the X-axis direction. The synchronous movement of the trolley 13 with the first X-axis track rod 121 and the second X-axis track rod 122 will cause the loading arm to move in the Y-axis direction, thereby achieving alignment adjustment of the loading arm in the Y-axis direction. That is, in this embodiment, the trolley 13 moves relative to the Y-axis track frame 11 by being driven by the X-axis track frame 12, rather than by active walking.
[0030] The inner sides of the first X-axis track rod 121 and the second X-axis track rod 122 are provided with an X-axis moving track 124. The moving trolley 13 is provided with rollers 131 corresponding to the X-axis moving track 124. Through the cooperation of the rollers 131 and the track, the moving trolley 13 can achieve stable operation relative to the X-axis track frame 12. In this embodiment, the X-axis moving track 124 is preferably a symmetrical double groove structure. The moving trolley 13 is composed of steel plates. The sides of the steel plates are equipped with eight rollers 131, four upper and four lower. The upper and lower rollers 131 are fitted into the double grooves to achieve sliding fit and support for the moving trolley 13.
[0031] The mobile trolley 13 is equipped with a drive unit, which includes a reduction motor 132 and a transmission assembly. The output shaft of the reduction motor 132 is connected to the transmission assembly, and the transmission assembly drives the roller 131 to rotate, thereby realizing the movement of the mobile trolley 13 relative to the X-axis moving track 124. In this embodiment, the transmission assembly is preferably a gear (not shown in the figure) and a rack 131. The gear is installed at the output shaft end of the reduction motor 132, and the gear meshes with the rack 131. The rack 131 is arranged along the length direction of the X-axis moving track 124 and fixed on either the first X-axis track rod 121 or the second X-axis track rod 122.
[0032] In this embodiment, each rod constituting the X-axis track frame 12 and the Y-axis track frame 11 is made of hollow rectangular steel pipe, which helps to further reduce the weight of the crossbeam frame 1.
[0033] The specific operating principle of this embodiment includes: suspending a conventional loading arm under a trestle bridge using a suspended truss device; during alignment, as needed, activating a drive mechanism or drive unit, driving the X-axis track frame 12 and the moving trolley 13 to move on the Y-axis moving track 119 to adjust the displacement of the loading arm in the Y-axis direction, and driving the moving trolley 13 relative to the X-axis moving track 124 to adjust the displacement of the loading arm in the X-axis direction, repeating this cycle until the loading arm is moved to the corresponding position; thus, this solution, by combining a conventional loading arm with this suspended truss device, forms a compact, stable, and low-cost automatic moving loading arm, solving the shortcomings of existing conventional loading arms.
