Description

Technical Field

[0001] The utility model relates to the technical field of box beams, in particular to an adjustable box beam auxiliary shelf. Background Art

[0002] At present, steel structures have the advantages of high strength, light weight, good overall rigidity, and strong deformation ability, so steel structures are widely used. Box beams are important workpieces in steel structures and have the advantage of high torsional rigidity. Due to the complex construction site environment, many box beams are sometimes placed directly on the ground, which may cause bumps and deformations to beams with triangular ribs or plugs, and may also cause paint damage, curvature of steel structures, and difficulties in lifting. Chinese Patent 202320477236.9 discloses "A Box Beam Auxiliary Shelf", announcement number CN219949038U, which discloses a box beam auxiliary shelf, belongs to the field of box beam technology, and includes a base, two round tubes are installed on the upper end of the base, and the round tubes are provided with internal threads. Threaded rods are installed in the round tubes through threads, and a fixed upper cover that can move up and down is installed between the upper ends of the two threaded rods. The manufactured box beam is transported to the site, and the beam structure is placed on the utility model by trailers, cranes, forklifts, etc. The number of auxiliary shelves increases with the length of the beam structure. After placement, other processes are carried out, which solves the problems of box beam triangular reinforcement or plug-in plates being easily deformed by collision, paint damage, curvature of steel structure, and difficulty in lifting.

[0003] However, this patent is only applicable to box beams of specific sizes and cannot adjust its own structure according to the sizes of different box beams, which makes it insufficiently practical. At the same time, the locking nut on the upper cover of the device is inconvenient to use and takes a long time to operate. Utility Model Content

[0004] In order to solve the above problems of the prior art, the utility model provides an adjustable box beam auxiliary shelf to solve the problems of insufficient practicality and long operation time of the device proposed in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an adjustable box beam auxiliary shelf, comprising a base plate, a movable groove is opened in the middle of the base plate along the length direction, a bidirectional screw is arranged in the movable groove, one end of the bidirectional screw is connected to the output end of the rotating motor, and a slider is symmetrically threaded at the positive and negative threads of the bidirectional screw, and the upper end of the slider is fixedly connected to a support frame, the two support frames are symmetrically arranged, and a limiting groove is set at the upper end of the support frame along the height direction, a sleeve is sleeved at the position of the limiting groove, a pressure rod is fixedly connected between the two sleeves, and a positioning assembly is installed on the sleeve.

[0006] With the above structural design, the bidirectional screw can move the two support frames, and then the distance between the two support frames can be determined according to the sizes of different box beams, so that the support frames and the box beams are in closer contact, thereby increasing the stability and practicality of the device.

[0007] Preferably, the positioning assembly includes a fixing frame fixedly connected to the outer surface of the sleeve, an insert block installed in the fixing frame, the middle part of the insert block is fixedly connected to the limit plate, a return spring is arranged between the limit plate and the sleeve, a cam is rotatably connected to the fixing frame, the cam abuts against one end of the insert block, and the insert block can be inserted into the limit groove to relatively fix the sleeve and the support frame.

[0008] With the above structural design, when the pressure rod needs to be fixed, the cam installed on the fixed frame is rotated, and the cam squeezes the insert block into the limit groove. At this time, the sleeve and the support frame are relatively fixed. When the pressure rod needs to be moved, the cam is rotated in the opposite direction. At this time, the reset function of the reset spring pops the insert block out of the limit groove, and the pressure rod can be removed from the support frame.

[0009] Preferably, a storage groove is provided at the lower end of the bottom plate, a hydraulic cylinder is fixedly connected in the storage groove, and a moving wheel is provided at the output end of the hydraulic cylinder.

[0010] The above structural design increases the mobility of the device, making it convenient for construction workers to move the box beam over a short distance. When the box beam does not need to be moved, the hydraulic cylinder can retract the moving wheels into the storage groove so that the device can be fixedly placed.

[0011] Preferably, a rubber pad is fixedly connected to a side of the support frame close to the box beam.

[0012] The above structural design is adopted to prevent the support frame and the box beam from squeezing each other and deforming the box beam.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. By moving the two support frames through the bidirectional screw rod, the device can determine the distance between the two support frames according to the size of different box beams. The support frames are in closer contact with the box beam, which increases the stability and practicality of the device.

[0015] 2. Set a positioning component to limit the movement of the pressure rod. When the pressure rod needs to be fixed, the cam installed on the fixing frame is rotated, and the cam squeezes the plug into the limit groove. At this time, the sleeve and the support frame are relatively fixed. When the pressure rod needs to be moved, the cam is rotated in the opposite direction. At this time, the reset function of the reset spring ejects the plug from the limit groove, and the pressure rod can be taken down from the support frame. This design is more convenient and quicker than the threaded connection operation. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] Working principle: the construction workers transport the manufactured box beam 15 to the site and place it on the utility model. The number of auxiliary shelves increases with the length of the box beam 15.
