Description

Technical Field

[0001] This utility model relates to the field of installation technology, and in particular to an installation structure for a heavy-duty lifting beam shaft. Background Technology

[0002] The heavy-duty lifting beam consists of two lifting beam shafts. Currently, the heavy-duty lifting beam shafts are installed by directly hoisting and pushing them into the mounting holes on the lifting beam. This requires two to three people to install properly. Previously, the installation of the lifting beam shafts required a huge amount of manpower and resources. In addition, the lifting beam shafts and the mounting holes are prone to collision and friction. In the current installation process of heavy-duty lifting beam shafts, there are problems such as high installation resistance, high manpower and resources consumption, difficulty in installation, difficulty in guiding during installation, and incorrect installation.

[0003] Based on the above defects and shortcomings, it is necessary to improve the existing technology and design a heavy-duty lifting beam shaft installation structure. Utility Model Content

[0004] The main technical problem solved by this utility model is to provide an installation structure for a heavy-duty lifting beam shaft that is simple to install, has low installation resistance, is easy to operate, and provides a guide at the front end to prevent misalignment during installation.

[0005] To solve the above-mentioned technical problems, the present invention provides a technical solution: a mounting structure for a heavy-duty lifting beam shaft, the mounting structure comprising:

[0006] Follower-side support wheel sets: Two sets of follower-side support wheel sets are installed at the mounting holes of the lifting beam and are symmetrically arranged below the mounting holes of the lifting beam;

[0007] The lead screw push assembly, which can be detached and installed on the lifting beam outside the lifting beam mounting hole and is located away from the follower side support wheel group, includes a bushing, a fixing plate, a handwheel lead screw, a square limit block, and a guide rolling unit. The bushing has a shaft hole for installing the lifting beam shaft. A fixing plate is installed on the flange plate at the outer end of the bushing. A handwheel lead screw is installed in the middle of the fixing plate. The handwheel of the handwheel lead screw is located on the outer side. The lead screw nut of the handwheel lead screw is located in the shaft hole. A square limit block is installed on the lead screw nut to limit the rotation of the lifting beam shaft. The outer end face of the lifting beam shaft has a groove that mates with the square limit block. The flange plate at the other end of the bushing is locked to the lifting beam with screws. Several sets of guide rolling units that roll with the internal lifting beam shaft are also installed on the bushing.

[0008] Preferably, the guide rolling unit includes right-angle plates and rollers. The two right-angle plates are arranged opposite each other and are attached to the outer end of the bushing by screws. The opposite surfaces of the two right-angle plates are provided with annular grooves, and the rollers are installed in the annular grooves. The bushing is provided with rectangular openings along the moving direction of the lead screw nut. The lower row of rollers in the annular grooves makes rolling contact with the lifting beam shaft through the rectangular openings.

[0009] Preferably, the follower side support wheel assembly includes a follower bracket and side support wheels rotatably mounted on the follower bracket. The follower bracket is mounted on the inner wall of the lifting beam, and the two side support wheels are symmetrically distributed below the lifting beam shaft. The outer rolling surface of the side support wheels can roll into contact with the outer wall of the lifting beam shaft.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] The screw push assembly guides the lifting beam shaft into the mounting hole, while the square limit block restricts the radial rotation of the lifting beam shaft. Several sets of guide rolling units roll into contact with the lifting beam shaft. Compared to sliding friction, rolling friction is much smaller, greatly reducing frictional resistance. The lifting beam shaft slides freely within the bushing, facilitating push-in and reducing manpower and material costs.

[0012] The follow-up side support wheel assembly provides guidance at the front end of the lifting beam shaft, reducing the possibility of misalignment during shaft installation. Attached Figure Description

[0020] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0021] Please see Figures 1 to 4The embodiments of this utility model include:

[0022] A mounting structure for a heavy-duty lifting beam shaft includes a follower-side support wheel assembly 1 installed at a lifting beam mounting hole 03 and a lead screw push assembly 2 that can be detachably installed at the outer end of the lifting beam mounting hole 03. The follower-side support wheel assembly 1 is located at the end of the lifting beam mounting hole 03 away from the lead screw push assembly 2.

[0023] The follower side support wheel assembly 1 includes a follower bracket 11 and side support wheels 12 rotatably mounted on the follower bracket 11. The follower bracket 11 is mounted on the inner wall of the lifting beam 01. The two side support wheels 12 are symmetrically distributed on the lower side of the lifting beam shaft 02. The outer rolling surface of the side support wheel 12 can roll into contact with the outer wall of the lifting beam shaft 02. The side support wheel 12 provides guidance at the front end of the lifting beam shaft 02 to prevent the lifting beam shaft 02 from being misaligned during installation.

[0024] The lead screw push assembly 2 includes a bushing 21, a fixing plate 22, a handwheel lead screw 23, a square limiting block 24, and a guide rolling unit 25. The bushing 21 has a shaft hole for installing the lifting beam shaft 02. The fixing plate 22 is installed on the outer flange plate of the bushing 21. The handwheel lead screw 23 is installed in the middle of the fixing plate 22. The handwheel 231 of the handwheel lead screw 23 is located on the outer side. The lead screw nut 232 of the handwheel lead screw 23 is located in the shaft hole. The square limiting block 24 that limits the rotation of the lifting beam shaft 02 is installed on the lead screw nut 232. The outer end face of the lifting beam shaft 02 has a groove that cooperates with the square limiting block 24. The flange plate at the other end of the bushing 21 is locked to the lifting beam 01 by screws. Several sets of guide rolling units 25 that roll with the internal lifting beam shaft 02 are also installed on the bushing 21.

[0025] The guide rolling unit 25 includes right-angle plates 251 and rollers 252. The two right-angle plates 251 are arranged opposite each other and are attached to the outer end of the bushing 21 by screws. The opposite surfaces of the two right-angle plates 251 are provided with annular grooves 250. The rollers 252 are installed in the annular grooves 250. The bushing 21 is provided with a rectangular opening 210 along the moving direction of the lead screw nut 232. The lower row of rollers 252 in the annular grooves 250 roll in contact with the lifting beam shaft 02 through the rectangular opening 210.

[0026] When the installation structure of the heavy-duty lifting beam shaft of this utility model is in operation, the lifting beam shaft 02 is first installed into the bushing 21 of the screw push assembly 2. The square limiting block 24 is inserted into the groove on the outer end face of the lifting beam shaft 02. The entire screw push assembly 2 is then attached to the lifting beam 01 outside the lifting beam mounting hole 03 by screws. The handwheel screw 23 is rotated by the handwheel 231. The rotation of the handwheel screw 23 drives the screw nut 232 to move. The screw nut 232 pushes the lifting beam shaft 02 toward the lifting beam mounting hole 03 through the square limiting block 24. The lifting beam shaft 02 continues to move forward. The two sets of follower side support wheels 1 roll to guide and support until the lifting beam shaft 02 is installed in place. Then, the screw push assembly 2 is disassembled and removed.
