Description

Technical Field

[0001] The utility model belongs to the technical field of monorail lifting beams, and in particular relates to a monorail lifting beam capable of realizing rotation. Background Art

[0002] Auxiliary transportation of coal mines is an important part of the daily production activities of coal mines. Ensuring the safety of the auxiliary transportation system of coal mines and improving transportation efficiency are of great significance to reducing the transportation costs of enterprises and increasing the production benefits of enterprises. Auxiliary transportation has become a weak link restricting the safe and efficient production of coal mines in the process of continuous transformation and upgrading of the coal mining industry towards high-end, mechanization and intelligence. With the increasing popularity of monorail crane transportation methods and the wide variety of materials and equipment that need to be transported in daily production underground in coal mines, the main manufacturers have also launched monorail crane lifting devices of different load capacities and types - monorail crane lifting beams according to actual needs.

[0003] At present, most of the monorail lifting beams on the market are mainly used to break through the transportation of large equipment. They have launched different types of monorail lifting beams with a load capacity of 16 tons, 32 tons and 48 tons. In terms of functional application, special lifting beams are relatively rare, especially those designed to solve a certain problem. For example, the steering problem of the hydraulic support during the installation and dismantling of the working surface. In the past, the monorail crane locomotive used a lifting beam to transport the hydraulic support to the vicinity of the installation position, and then exited the work site after removing the hydraulic support, or directly placed the hydraulic support on the hydraulic support rotating platform and left the work site. After that, the installer used a column return winch, hydraulic jack or hydraulic support rotating platform to rotate it 90°, and finally put it in place and connected it to the chute. It has many links, low efficiency, high labor intensity for workers, and unsafe factors. For this reason, the utility model proposes a monorail lifting beam that can realize rotation.

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Example 1

[0024] See also Figures 1 to 5 , is the first embodiment of the utility model, which provides a technical solution: a monorail lifting beam capable of rotating, comprising

[0025] Two upper hanging assemblies slidably mounted on the bottom of the hanging beam 4 include two movable cross beams 2 movably mounted on the bottom of the hanging beam 4 and an I-beam 3 connected between the two movable cross beams 2, and hinge seats 31 are fixed to the front and rear surfaces of the I-beam 3. The two upper hanging assemblies are connected by a connecting rod, so that the two upper hanging assemblies can slide synchronously on the hanging beam 4;

[0026] And a rotating beam assembly 1 is installed below the two upper hanging assemblies, and connecting columns 5 are provided at the four corners of the rotating beam assembly 1. The connecting columns 5 are connected to the hinge seat 31 through a pin shaft. The rotating beam assembly 1 includes a load-bearing beam 11 and a rotating lower beam 12 rotatably installed at the bottom of the load-bearing beam 11, and hydraulic hoists 16 are installed at the four corners of the rotating lower beam 12.

[0027] Among them, the movable cross beam 2 includes a beam body 1 21 and a beam body 2 22 which are connected together by a rotating shaft. The beam body 2 22 can rotate around the beam body 1 21, so that the beam body 2 22 can rotate freely when the lifting beam turns horizontally. A load-bearing trolley is installed on the top of both ends of the beam body 22, and the load-bearing trolley is movably installed on the hanging beam 4, so that the movable cross beam 2 can move smoothly on the hanging beam 4.

[0028] Wherein, both ends of the beam body 21 are connected to the ends of the I-beam 3 through pins.

[0029] Among them, the rotating beam assembly 1 also includes a rotating load-bearing outer ring 13 fixed at the top center of the load-bearing beam 11 by bolts, and a rotating load-bearing inner ring 14 rotatably installed on the inner wall of the rotating load-bearing outer ring 13 and with the bottom end extending to the bottom of the load-bearing beam 11. The center of the rotating lower beam 12 is fixedly connected to the rotating load-bearing inner ring 14 by bolts, so that the rotating lower beam 12 can rotate smoothly at the bottom of the load-bearing beam 11.

[0030] Among them, the rotating beam assembly 1 also includes two hydraulic cylinders 15 symmetrically installed on the top of the load-bearing beam 11. One end of the hydraulic cylinder 15 is hinged to the load-bearing beam 11 through a rotating shaft, and the other end of the hydraulic cylinder 15 is connected to a seat on the top of the rotating lower beam 12 through a rotating shaft, so that the two hydraulic cylinders 15 can push the rotating lower beam 12 to rotate at the bottom of the load-bearing beam 11 after being started subsequently.

[0031] A circular hole is provided at the center of the load-bearing beam 11 for installation of the rotary load-bearing outer ring 13 , the rotary load-bearing inner ring 14 , the stand and other structures.

[0032] In summary, in actual use, the rotating beam assembly 1 can lift the working surface hydraulic support below through four hydraulic hoists 16, thereby realizing the lifting and lowering function of the working surface hydraulic support. At the same time, because the rotating beam assembly 1 has a rotatable function, the rotation function of the working surface hydraulic support can also be realized when lifting the working surface hydraulic support, thereby effectively shortening the installation time of the working surface hydraulic support. There is no need to arrange a winch driver at each end of the cut eye to operate the return column winch to pull, which can save 2 people, achieve staff reduction and efficiency improvement, and simplify the installation process. At the same time, when the hydraulic support is reversed, lifted and lowered, the operator is far away from the working position, avoiding injuries caused by tilting between hydraulics, anchor rod falling, etc., and on-site operations are also safer.

[0033] Example 2

[0034] See also Figures 1 to 6 , which is the second embodiment of the present utility model. This embodiment is based on the previous embodiment, but the difference is that the bottom end of the connecting column 5 passes through the bottom of the load-bearing beam 11 and is welded to a circular base 51, and two triangular side protrusions 52 are welded to the surface of the circular base 51. An annular positioning rubber ring 111 corresponding to the circular base 51 is installed at the four corners of the bottom surface of the load-bearing beam 11, and the inner wall of the annular positioning rubber ring 111 is provided with an annular groove 112 corresponding to the triangular side protrusion 52, and the triangular side protrusion 52 is embedded in the annular groove 112. When the connecting column 5 is installed with the load-bearing beam 11 in the early stage, it can first pass through from the bottom of the load-bearing beam 11 to the top of the load-bearing beam 11, and the circular base 51 can be pushed into the inner side of the annular positioning rubber ring 111, and the triangular side protrusion 52 is inserted into the annular groove 112, so that the preliminary connection between the connecting column 5 and the load-bearing beam 11 can be achieved at this time, and then the top end of the connecting column 5 can be connected to the hinge seat 31 through the pin shaft, so that the connecting column 5 will not be easily separated from the load-bearing beam 11 when it is not connected to the hinge seat 31, thereby improving the installation convenience of the connecting column 5. The annular positioning rubber ring 111 is made of rubber material and can undergo elastic deformation, and the inner diameter of the annular positioning rubber ring 111 is adapted to the outer diameter of the circular base 51.

[0035] Although embodiments of the present invention have been shown and described (see the detailed description above for details), it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
