Background
The multifunctional hydraulic working platform for the ship consists of two parts, wherein the lower part is a main frame which is responsible for jacking and walking the platform; the upper part is a working frame. The main frame of the hydraulic working platform can carry different types of working frames, thereby extending multiple use functions. The rudder blade mounting platform is formed by carrying a rudder blade working frame and can be used for mounting rudder blades.
Disclosure of Invention
The invention aims to solve the technical problem of providing a reliable mechanical device for supporting and fixing a platform for a large-scale marine multifunctional hydraulic platform. When the hydraulic platform works and reaches a designated position, the support rod device is manually lowered to touch the ground so as to prevent the platform from falling; when the traveling mechanism of the hydraulic platform needs to be reversed, namely, the traveling mechanism is longitudinally moved or transversely moved, the supporting rod device is manually lowered to be grounded, and then the wheels of the traveling mechanism are reversed.
A threaded support rod with a locking device comprises a threaded support rod, a support rod spherical saddle, a locking nut, a hand wheel, a screw rod support seat, a spherical gland, a support nut pin shaft, a threaded support seat mounting plate, an elastic pin and a self-locking nut with an insert;
the top end of the threaded support rod is provided with a hand wheel through an elastic pin; the bottom end of the threaded support rod is of a spherical structure, is arranged on the spherical saddle of the support rod through the spherical gland and is connected by screws;
the threaded support seat mounting plate is welded on the hydraulic platform and is connected with the screw rod support seat through a screw;
the locking nut is locked with the self-locking nut with the insert through a supporting nut pin shaft.
The material of the threaded support rod is 40 Cr.
When the threaded supporting rod is in a storage state, the locking nut is located above the screw rod supporting seat.
When the threaded supporting rod is in a release state, the locking nut is positioned below the screw rod supporting seat.
The invention provides a threaded support rod with a locking device, and a mechanical support rod device with reliable performance plays a role in supporting and fixing a hydraulic working platform, and ensures the safety of constructors during workpiece installation.
The hydraulic platform has the characteristics of simple design, convenient operation and reliable performance, and is not only suitable for the hydraulic platform, but also applicable to various hoisting machines. The thread support rod device adopts the special design of a spherical saddle, and the angle of the spherical saddle can be adjusted according to the ground condition, so that the support rod can be firmly grabbed, the support rod cannot rock due to uneven ground, and the safety of a hydraulic platform during workpiece installation is ensured. The support rod locking nut is simple in structural form and convenient to disassemble and assemble.

Detailed Description
The following detailed description of embodiments of the invention refers to the accompanying drawings.
The invention relates to a mechanical support rod device adopting a manual operation mode, in particular to a threaded support rod with a locking device, which comprises a threaded support rod 1, a support rod spherical saddle 2, a locking nut 3, a hand wheel 4, a screw rod support seat 5, a spherical gland 6, a support nut pin shaft 7, a threaded support seat mounting plate 8, an elastic pin 9 and a self-locking nut 10 with an insert, wherein the threaded support rod is provided with a screw rod;
the top end of the threaded support rod 1 is provided with a hand wheel 4 through an elastic pin 9, an operator stands above the hydraulic platform to rotate the hand wheel 4, and the lifting or lowering of the threaded support rod 1 is controlled.
The bottom end of the threaded support rod 1 is of a spherical structure, is arranged on the support rod spherical saddle 2 through a spherical gland 6 and is connected by screws; the angle of the support rod spherical saddle 2 can be adjusted at will to adapt to various ground environments, so that the threaded support rod 1 can firmly grab the ground and cannot shake due to uneven ground.
The threaded support seat mounting plate 8 is mounted at the designated position of the hydraulic platform by a welding method and is connected with the screw rod support seat 5 by screws; the mounting position and the length of the threaded support rod 1 are determined according to the jacking height of the hydraulic working platform, and meanwhile, the use of operators is convenient to use.
The locking nut 3 is locked with the self-locking nut 10 with the insert through the supporting nut pin shaft 7.
The material of the threaded support rod 1 is 40Cr, and the alloy structural steel can bear large load.
When the hydraulic working platform moves, the threaded support rod 1 is in a storage state, and the locking nut 3 is positioned above the screw rod support seat 5. When the hydraulic working platform reaches a designated position, the locking nut 3 is taken down, the hand wheel 4 is rotated, and the threaded support rod 1 is lowered to the ground. After confirming that the support rod spherical saddle 2 firmly grabs the ground, the locking nut 3 is locked below the screw rod supporting seat 5 and tightly attached to the screw rod supporting seat 5. At this time, the hydraulic platform is fully carried by the threaded support rod 1 and the lock nut 3 by the weight of the workpiece.
When the traveling mechanism of the hydraulic working platform performs wheel reversing, the operation method is similar to the process.
