Description

Technical Field

[0001] The utility model relates to the field of combined steel pedestals, in particular to an assembled steel pedestal. Background Art

[0002] Highway bridges, especially highway bridges, require prefabricated small box girders to truly achieve solid interior and exterior beauty and blend in with nature. At present, the prefabrication of bridge beams and slabs generally adopts the method of centralized prefabrication in prefabrication plants, which is prefabricated first and then installed. In the process of beam and slab prefabrication, several bridge bases are first made according to the number of beam and slab prefabrication, construction period, and construction sequence, and each beam and slab is prefabricated on the slab base. Due to the different spans of bridges, the required beam and slab lengths are also different, and different bases must be made;

[0003] After searching, the authorization announcement number is CN214981975U, which is a prefabricated box beam combined steel pedestal. Although the device can timely adjust the position of the steel support according to the size of the prefabricated box beam, there is no need to make bases of different specifications, which reduces the production cost, but the device has the following problems:

[0004] 1. The support plate of the device is a suspended design. Although the telescopic rod and suction cup can improve the overall stability of the equipment, it is difficult to support the steel section only by the telescopic rod due to the heavy bridge beams and slabs;

[0005] 2. When the telescopic rod retracts due to the gravity of the beam and slab, it is very easy to cause the positive and negative screws to bend, causing the device to be unable to be used normally.

[0006] Therefore, an assembled steel pedestal is proposed to solve the above problems. Utility Model Content

[0007] The purpose of the utility model is to provide an assembled steel pedestal in order to solve the above-mentioned problem, which improves the support plate of the device into a suspended design. Although the telescopic rod and the suction cup can improve the overall stability of the equipment, due to the heavy bridge beams and slabs, it is difficult to support the steel section only by the telescopic rod.

[0008] The utility model achieves the above-mentioned purpose through the following technical scheme: an assembled steel pedestal, comprising: a base, a concrete block is fixedly installed on the top of the base, and vertical plates are fixedly installed on both sides of the top of the base; a supporting mechanism, which is installed on the top of the base and can support the bridge beams and slabs; wherein the supporting mechanism comprises a bidirectional screw rod installed through the inside of the concrete block, the two ends of the bidirectional screw rod are rotatably connected to the two vertical plates through bearings, a servo motor is fixedly installed on one side of one of the vertical plates, the output end of the servo motor passes through the vertical plate and is fixedly connected to one end of the bidirectional screw rod, and the two sides of the surface of the bidirectional screw rod are threadedly connected to support components.

[0009] Preferably, the support assembly includes two support seats threadedly connected to both sides of the surface of the bidirectional screw, a base plate is installed on the top of the support seat, a supporting steel is fixedly installed on the top of the base plate, slide rails are fixedly installed on the front and rear sides of the top of the base, and slide grooves are opened on the front and rear sides of the bottom of the support seat, and the slide rails and the slide grooves are slidably connected.

[0010] Preferably, a plurality of installation cavities are installed through the interior of the support seat, an electric push rod is installed inside the installation cavity, and a suction cup is fixedly installed at the telescopic end of the electric push rod.

[0011] Preferably, limiting bolts are installed on both the front and rear sides of the top of the supporting steel section, and locking nuts are threadedly connected to the surfaces of the limiting bolts.

[0012] Preferably, two sliding rods are fixedly mounted on adjacent sides of the two vertical plates, one end of the sliding rod away from the vertical plate passes through the support seat and is fixedly connected to the concrete block, and the sliding rod is slidably connected to the support seat.

[0013] Preferably, screws are installed penetratingly around the top of the base plate, and the base plate is fixedly connected to the support seat by screws.

[0014] Preferably, a buffer pad is fixedly mounted on one side of the top of the base, and the top of the buffer pad is connected to the bottom of the servo motor.

[0015] The beneficial effects of the utility model are:

[0016] 1. When supporting the bridge beam, the bidirectional screw is driven to rotate by the servo motor, and the bidirectional screw drives the two support seats to move inward or outward synchronously through the threaded connection with the support seat, and the spacing between the two support steels is adjusted so that it can be adjusted in time according to the size of the prefabricated box beam. The bottom of the support seat is slidably connected with the slide rail and the base. When the support steel is stressed, the force is transmitted to the surface of the base as a whole, which makes it easier for the device to support the prefabricated box beam as a whole, and avoids the situation where the positive and negative screws are easily bent when the telescopic rod retracts due to the gravity of the beam, resulting in the device being unable to be used normally;

[0017] 2. After the distance between the two support bases is adjusted, the electric push rod is driven to work. The electric push rod drives the suction cup to descend and contact the top of the base. When the electric push rod continues to descend, the gas inside the suction cup is squeezed out, so that the internal and external pressures of the suction cup are changed, and the suction cup is firmly adsorbed to the top of the base, so as to improve the support stability of the support base.
