The split mast structure has the advantages that the front-back split structure is adopted in the section, the rear mast 3 is utilized to replace the outer tower mast of the traditional structure, the section size is greatly reduced, and the stability is better because the structure is a square box structure.
Specifically, the split mast structure comprises a driving piece and a mast main body, wherein the section of the mast main body perpendicular to the length direction is square, the mast main body comprises a rear side mast 3 and a front side mast 1 which is positioned outside the rear side mast 3 and is arranged in a sliding manner along the length direction of the rear side mast 3 through a side guide rail sliding chute assembly; the opposite surfaces of the front mast 1 and the rear mast 3 are respectively provided with a containing half groove 13b along the length direction, the driving piece is arranged in a containing groove body formed by the two containing half grooves 13b, one end of the driving piece is fixed in the containing half groove 13b of the rear mast 3, and the other end of the driving piece is connected to the top end of the front mast 1 so as to drive the front mast 1 and the rear mast 3 to perform relative movement; the front mast 1 is provided with a working device 8 moving with the front mast 1 on a side facing away from the rear mast 3.
As shown in fig. 3, the mast body has a square frame-like cross section and a compact structure, the mast body comprises a rear mast 3 and a front mast 1, the opposite surfaces of the front mast 1 and the rear mast 3 comprise a connecting plane 13a and a receiving half groove 13b, and the receiving half groove 13b is a polygonal groove structure with the mast bent inwards. The receiving half groove 13b is located at a central position in the front-rear direction of the opposite faces of the front mast 1 and the rear mast 3, and the connection planes 13a are located on both sides of the receiving half groove 13 b.
The front mast 1 and the rear mast 3 are connected into a mast body by a lateral guideway and chute assembly, and at this time, the connection plane 13a of the front mast 1 and the connection plane 13a of the rear mast 3 are in contact, so that the mast body structure is stable.

More importantly, the oil cylinder can be protected, and the installation mode of the external oil cylinder is adopted, so that the installation and maintenance of the oil cylinder are convenient. Further, the cylinder end of the lifting cylinder 6 is fixed on a cylinder mounting seat 7 arranged at the bottom of the half groove 13b of the rear mast 3, the top end of the rear mast 3 is provided with a guide sleeve, and the piston rod end penetrates through the guide sleeve and is connected to a cylinder hinge hole protruding from the top end of the front mast 1, as shown in fig. 5 and 6.
In some further embodiments, the axis of the lifting cylinder 6 is located at the center of the accommodating groove body, and the design makes the lifting cylinder 6 work to drive the front side mast 1 to linearly stretch and retract relative to the rear side mast 3, so that the front side mast 1 does not generate component force relative to the rear side mast 3.
As shown in fig. 4, the front mast 1 is provided with a working device 8 moving with the front mast 1 on a side facing away from the rear mast 3. Specifically, the working device 8 can slide along the front mast 1, and working rails along the length direction, that is, the up-down direction in the drawing, are designed on the left side surface and the front and rear side surfaces of the front mast 1, and the working device 8 is slidably connected to the working rails through a slider.
The top of the front mast 1 is connected with a lifting pulley block 2 through bolts, and the bottom of the front side and the back side of the front mast 1 are connected with a pressurizing pulley 11. The top of the rear mast 3 is provided with a hinged support for connecting a steel wire rope, the top surface of the working device 8 is connected with the hinged support at the top of the rear mast 3 by bypassing the lifting pulley block 2 through the lifting steel wire rope 9, and the bottom surface of the working device 8 is connected with the hinged support at the top of the rear mast by bypassing the pressurizing pulley 11 through the pressurizing steel wire rope 10.
When the lifting device works, when the lifting oil cylinder 6 stretches out to push the front side mast 1 to slide upwards, the lifting pulley block 2 ascends along with the front side mast 1, and the lifting steel wire rope 9 drives the working device to move upwards, so that lifting action is completed. Conversely, when the lifting cylinder 6 is retracted, the front mast 1 slides downwards along with the lifting cylinder 6, the pressurizing pulley 11 descends along with the front mast 1, and the pressurizing pulley 11 drives the working device to move downwards through the pressurizing steel wire rope 10, so that the pressurizing action is completed.
Because the front mast 1 is outside the rear mast 3, and the lifting pulley block 2 is arranged at the top end of the front mast 1, the pressurizing pulley 11 is arranged at the bottom ends of the front side and the rear side of the front mast 1, so that the lifting pulley block 2 and the pressurizing pulley 11 are convenient to install.
The pressurized pulley block with the traditional structure can only be arranged on the inner side due to the mast structure, the structure is not easy to assemble and maintain, and the requirement on the installation space increases the requirement on the size of the outer tower. The mast structure of front-back split type is adopted, the pressurizing pulley 11 is hung on the side face of the front side mast in an externally hung mode, space is not occupied, and assembly and maintenance are convenient. The lifting pulley block of the original structure has larger size due to the mast structure, and two groups of pulleys are required to be arranged together to guide the steel wire rope to the required position. The application can complete guiding by adopting a group of lifting pulley blocks 2 due to smaller cross section size.
Further, the center of the lifting pulley block 2 is arranged to coincide with the axis of the lifting oil cylinder 6. The axis of the lifting oil cylinder 6 is arranged to coincide with the center of the lifting pulley block 2, so that the lifting oil cylinder 6 is only pulled and pressed when the whole structure is stressed, and is free from bending moment and better in stress.
As shown in fig. 8, the front side mast 1 and the rear side mast 3 of the present application are connected by a side rail chute assembly. In particular, the track chute assembly comprises a track 5 and a clasping jaw 4, the track being arranged lengthwise on the front mast 1 and the rear mast 3.

The other holding claw 4 is fixed at the bottom end of the front side mast 1 and is in sliding connection with a guide rail on the rear side mast 3.
In some further embodiments, in order to ensure the service life of the holding claw 4 and the fixing effect on the front side guide rail and the rear side guide rail, the holding claw 4 is made of a material with high wear resistance and hardness, and the contact surface of the holding claw 4 and the guide rail 5 can be further heat treated to ensure the service life.
In the traditional structure, the spout of outer tower is arranged at the medial surface of U type structure, and processing is inconvenient. The front mast and the rear mast of the utility model adopt front-back split structures, and the guide rail 5 and the holding claw 4 of the front mast and the rear mast can be arranged on the outer side of the mast, so that the front mast and the rear mast are convenient to process.
