Detailed Description

The following is a specific embodiment of the present invention, and the technical solution of the present invention is further described with reference to the accompanying drawings, but the present invention is not limited to these examples.

As shown in fig. 1, a suspension support structure of a logistics device is arranged on a beam 1 arranged side by side, and has a beam suspension structure for being arranged on the beam 1.

The existing beam 1 is divided into H-shaped steel and I-shaped steel, but the flanges of the H-shaped steel are flat parts, the upper surface and the lower surface of the H-shaped steel are parallel, the flanges of the I-shaped steel are arc parts, and the upper surface of the H-shaped steel is inclined. The flanges of the two have different shapes and thicknesses, and the beam suspension structure needs to be mounted on the flanges. In the prior art, a beam suspension structure generally includes an upper press block abutted to the upper surface of a beam flange, a lower press block abutted to the lower surface of the beam flange, and a cushion block arranged between the upper press block and the lower press block according to the thickness of the flange. In an H-beam, for flanges of different thickness, it is necessary to design spacers of different thickness. On the I-steel beam, not only cushion blocks with different thicknesses can be designed, but also corresponding upper pressing blocks can be designed according to the shape of the upper surface of the flange. Based on this, the beam suspension structure in the prior art has the problem of low applicability.

In this application, in order to improve applicability of the beam suspension structure, as shown in fig. 2, the beam suspension structure includes a support bar 21, two ends of the support bar 21 are respectively provided with a pressing block 22, and a receiving cavity for inserting a flange of the beam 1 is formed between the pressing block 22 and the support bar 21; the press block 22 is provided with a bolt fastener 23; the press block is at least partially elastic so that the press block 22 can be pressed against the flange by its elastic deformation, while the bolt fastener 23 can maintain the press block 22 pressed against the flange by fastening the press block 22 to the support bar 21. The supporting bar 21 may be angle iron, and the bolt fastener 23 is connected by an M12 bolt.

In use, the position of the nut in the bolt fastener 23 on the threaded rod is adjustable. In the process of rotating and moving downwards, the nut contacts the pressing block 22, and the nut moves downwards continuously, so that the pressing block 22 is pressed to deform until a part of the pressing block 22 is completely tightly attached to the upper surface of the flange. Therefore, the cross member 1 can be securely coupled between the support bar 21 and the pressing block 22 regardless of the thickness shape.

In order to improve the adjustability of the pressing block 22 and to avoid the pressing block 22 from being deformed reversely by the load force, as shown in fig. 3, it is preferable in this embodiment that a surface of the pressing block 22 close to the supporting bar 21 is an arc surface with a middle portion protruding in a direction away from the supporting bar 21. While an adjustment hole 221 for connection with the bolt fastener 23 is provided at the apex thereof. The portion of the pressing piece 22 on the side of the apex near the free end forms a fixing portion that is in close contact with the flange. Further, in the vertical direction, the washer and the nut of the bolt fastener 23 each have a portion on the vertical surface of the flange. In addition, since the pressing block 22 is deformed, the center of the adjustment hole 221 thereof is displaced. Therefore, the diameter of at least one end of the adjusting hole 221 is larger than the outer diameter of the connecting screw of the bolt fastener 23, and only one of the connecting holes or adjusting holes 221 provided in the support bar 21 is provided with a collar portion for preventing the connecting screw from moving in a non-axial direction in cooperation with the outer diameter of the connecting screw. For example, as shown in fig. 3, the adjusting hole 221 may be in a circular truncated cone shape, a hoop portion is formed at a narrow end of the adjusting hole 221, the connecting screw is inserted into the adjusting hole 221, and when the pressing block 22 rotates toward the supporting bar 21 by displacement of the nut on the connecting screw, the central axis of the connecting screw is also displaced, so that a section of the connecting hole perpendicular to the axial direction thereof is in a bar shape to provide a movable range of the connecting screw. At this time, since the nut is usually mounted above the pressing block 22, the adjustment hole 221 is preferably in a right circular truncated cone shape.

Since the support bars 21 are used for loading conveyors and cargo, in order to further enhance the loading capacity thereof, the beam suspension structure in this application comprises a pair of support bars 21, the relative distance between the two support bars 21 being adjustable. At least 4 connection sites are realized by at least two support bars 21, and the load reliability is increased.

Through above-mentioned structural design of this application, crossbeam suspended structure has stronger load capacity, can be used to the heavier conveyer of load and heavier goods, therefore correspondingly, other components of crossbeam suspended structure also need to carry out intensity enhancement transformation to improve this hoist device holistic load capacity.

The column 33 is axially parallel to the fixed connecting rod 31, and the side surface of the column 33 is connected with the fixed connecting rod 31; the post 33 is provided with a through hole to which the adjustable link 32 is connected. When installed, the adjustable link 32 passes through the through-hole and a first adjustment nut is provided at a portion of the adjustable link 32 adjacent to the support bar 31 with respect to the column 33. Preferably, in this embodiment, the post 33 is welded to the fixed link 31. The cylindrical round steel is preferable because the column part 33 needs to be provided with a through hole, so that the cylindrical round steel can be processed by one cutter when the through hole is provided with the advantages of better concentricity, convenient installation and wide adjustable range. The welding of the whole round steel side surface and the fixed connecting rod 31 can effectively strengthen the connecting structure, and further, the fixed connecting rod 31 at least comprises two connecting surfaces, for example, in fig. 4, angle steel is adopted as the fixed connecting rod 31, and the two inner connecting surfaces are connected with the side surfaces of the column part 33, so that the connecting strength is further improved.

The angle bar 41 includes an X-surface and a Y-surface, and the X-surface or the Y-surface is provided with a plurality of fixing holes 411 for connection with a wall. The plurality of fixing holes are fixed with the wall body through expansion bolts, so that the structural strength is greatly enhanced. Further, the support base 42 is also provided with a support reinforcement for reinforcing the supporting function. In fig. 6, two angle bars 41 are included, the angle bars 41 are connected by an upper angle steel and a lower angle steel, and the lower angle steel forms a supporting seat 42.

One side panel of the connecting angle steel is overlapped and welded with the angle iron rod 41, and the other side panel is overlapped and welded with the lower angle steel. The welding mode between the surfaces can effectively improve the welding area, thereby improving the fixing strength. The angle bar 41 may be connected to the wall through the fixing hole 411, or may be directly welded to the support bar 21 as shown in fig. 5. In fig. 7, a supporting seat 42 is formed of angle steel, which is surface-welded to the angle bar 41. An inclined support reinforcement is also provided between the angle steel and the angle bar 41. The supporting reinforcement can also be made of angle iron directly, and the side panels are overlapped and welded with the supporting seat 42 and the angle iron rod 41 during connection.
