Description

Technical Field

[0001] This utility model belongs to the field of bridge construction equipment technology, and specifically relates to an electric device for installing supports in a precast box girder yard. Background Technology

[0002] In the field of post-tensioned prestressed concrete simply supported beams, the installation of bearings has always been a difficult problem for technicians. Traditional on-site bearing installation techniques usually involve using a forklift to directly lift the bottom of the bearing and align it with the embedded plate at the bottom of the precast beam. The disadvantages of this method are that it requires a lot of manpower, is slow, and is unsafe for forklifts to directly lift the bearing and align it with the embedded plate. The bearing is easy to fall and cause damage, so it cannot meet the requirements for on-site bearing installation and poses a risk of bearing falling and personnel injury, which can easily lead to quality accidents. Summary of the Invention

[0003] In order to solve the above problems, the purpose of this utility model is to provide a support mounting electric device.

[0004] To achieve the above objectives, the electric mounting device for the support provided by this utility model includes bullseye bearings, a tray, sleeves, an electric telescopic rod, a base, and casters. The tray is horizontally positioned; multiple bullseye bearings are spaced apart and mounted on the top surface of the tray; the four corners of the tray are each connected to the upper end of a sleeve; the sleeve consists of an upper sleeve and a lower sleeve, with the lower part of the upper sleeve inserted into the upper inner part of the lower sleeve; the upper end of the electric telescopic rod is connected to the center of the bottom surface of the tray; the base is horizontally positioned, with its four corners and the center of its top surface simultaneously connected to the lower ends of four sleeves and the electric telescopic rod; and a caster is mounted at each of the four corners of the bottom surface.

[0005] The base diameter of the bullseye bearing is 10mm, and the ball diameter is 50mm.

[0006] The tray is 1000mm long, 950mm wide, and 10mm thick.

[0007] The upper sleeve is 500mm long and 40mm in diameter; the lower sleeve is 500mm long and 50mm in diameter.

[0008] The base is 840mm long and 50mm high.

[0009] The diameter of the caster wheel is 100mm.

[0010] The electric support mounting device provided by this utility model has the following beneficial effects:

[0011] 1) It can ensure accurate alignment between the support and the embedded plate at the bottom of the precast beam.

[0012] 2) It can reduce the problem of support damage caused by collision between the support and the bottom of the beam.

[0013] 3) It can prevent personal injury caused by the support falling off due to the back-and-forth alignment during the installation process.

[0014] 4) It is easy to operate and also greatly saves labor costs and post-processing costs. Attached Figure Description

[0019] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0020] like Figures 1-4 As shown, the electric mounting device for the support provided by this utility model includes bullseye bearings 1, a tray 2, sleeves 3, an electric telescopic rod 4, a base 5, and casters 6. The tray 2 is horizontally positioned. Multiple bullseye bearings 1 are spaced apart and mounted on the top surface of the tray 2. The four corners of the tray 2 are connected to the upper end of a sleeve 3. The sleeve 3 consists of an upper sleeve and a lower sleeve, with the lower part of the upper sleeve inserted into the upper inner part of the lower sleeve. The upper end of the electric telescopic rod 4 is connected to the middle of the bottom surface of the tray 2. The base 5 is horizontally positioned, with its four corners and the middle of its top surface simultaneously connected to the lower ends of four sleeves 3 and the electric telescopic rod 4. A caster 6 is mounted at each of the four corners of the bottom surface.

[0021] The base diameter of the bullseye bearing 1 is 10mm, and the diameter of the ball bearing is 50mm.

[0022] The tray 2 is 1000mm long, 950mm wide, and 10mm thick.

[0023] The upper sleeve of the sleeve 3 is 500mm long and 40mm in diameter; the lower sleeve is 500mm long and 50mm in diameter.

[0024] The base 5 is 840mm long and 50mm high.

[0025] The diameter of the caster wheel 6 is 100mm.

[0026] The method of using the electric support installation device provided by this utility model is described as follows: This device is mainly used for the installation of supports 7 in the precast box girder yard. Workers move the cured precast box girder 8 to the lifting platform in the lifting area. Then, the support 7, matching the precast box girder 8, is placed on the bullseye bearing 1 of the device's tray 2. Next, the device is manually pushed to the bottom of the precast box girder 8 using casters 6, and the casters 6 are used to roughly align the support 7 with the embedded plate at the bottom of the precast box girder 8. Then, the electric telescopic rod 4 is used to lift the device until the distance between the tray 2 and the embedded plate reaches two centimeters. Afterward, the bullseye bearing 1 on the tray 2 is used to finely align with the bolt holes on the embedded plate. Finally, bolts are used to fix the support 7 to the bottom of the precast box girder 8. After the support 7 is installed, the device is disassembled, stored, and awaits the next use for support 7 installation.
