Description

Technical Field

[0001] The present invention relates to the technical field of equipment installation, and specifically to a roller inserting device in a fully restricted space. Background Art

[0002] In the field of industrial equipment installation, the hoisting of equipment in restricted spaces has always been one of the construction difficulties. Especially in production lines in industries such as metallurgy, chemical engineering, and building materials, the installation positions of equipment are often restricted by space, and there are obstacles or adjacent components in all four directions of up, down, left, and right, making it difficult to implement traditional hoisting methods. For example, equipment such as rollers in rolling mill production lines and support rollers in annealing furnaces usually need to be installed in narrow frames or bases, and the gaps with surrounding structures are extremely small, making it impossible to use conventional lifting machinery or rigging for hoisting. In addition, due to the long length of equipment such as rollers and the weight usually being less than 2 tons, using large lifting equipment not only has high costs but may also be inoperable due to space limitations.

[0003] In the prior art, for the installation of equipment in such fully restricted spaces, it is usually necessary to rely on complex auxiliary tooling or adjust the position of the lifting points, but there are still problems such as cumbersome operation and low efficiency. Some solutions rely on wire rope rigging or temporary support structures, which not only increase the construction risks but may also affect the installation accuracy of the equipment. Summary of the Invention

[0004] The present invention aims to solve the above problems, and thus provides a roller inserting device in a fully restricted space with convenient operation.

[0005] The technical solution adopted by the present invention to solve the above problems is: A roller inserting device in a fully restricted space, including a chassis frame. One side of the bottom of the chassis frame is provided with a set of tires. On the top of the chassis frame and on the side where the tires are located, a positioning frame is provided. A connecting mechanism for connecting the roller is slidably connected longitudinally in the positioning frame, and a lifting mechanism is provided between the top of the positioning frame and the connecting mechanism.

[0006] The present invention adopting the above technical solution, compared with the prior art, its prominent feature is: Through the combined design of the movement of the chassis frame and the tires, and in cooperation with the longitudinally slidable connecting mechanism and the lifting mechanism in the positioning frame, the problem of limited operation space existing in the installation of traditional restricted space equipment is effectively solved. The construction complexity is significantly reduced, and the potential safety hazards brought by wire rope rigging are avoided. Through the coordinated action of the lifting mechanism and the positioning frame, the translation, height lifting, and level adjustment of the roller in the restricted space are realized, overcoming the defects such as difficult adjustment of the lifting points and low installation efficiency caused by space limitations in the traditional method.

[0007] As a preference, a further technical solution of the present invention is: Furthermore, the positioning frame includes a pair of columns, with a crossbeam provided between the tops of the columns. There are sliding grooves between the opposite faces of the columns, and the connecting mechanism is slidably connected in the sliding grooves. The design of the sliding grooves provides stable guiding support for the connecting mechanism, ensuring both the overall rigidity of the device and the smooth lifting and lowering of the connecting mechanism.

[0008] Furthermore, there are diagonal braces between the columns and the chassis frame, enhancing the structural strength of the positioning frame, effectively dispersing the load stress during the hoisting process, and improving the stability of the device during the translation and lifting of the idler.

[0009] Furthermore, the connecting mechanism includes a sliding plate that slides along the sliding grooves between the columns. A connecting plate is provided outside the chassis frame opposite the middle of the sliding plate. A sleeve is provided between the sliding plate and the connecting plate. Through holes are provided on the sliding plate and the connecting plate opposite the sleeve, which can adapt to the dimensional changes of the idler drive shaft, ensure stable connection, and at the same time facilitate the quick disassembly and assembly with the idler bearing seat, improving the construction efficiency.

[0010] Furthermore, the inner diameter of the sleeve is larger than the outer diameter of the drive shaft of the idler to be installed, ensuring that the drive shaft can pass through smoothly.

[0011] Furthermore, connection holes are provided on the connecting plate and outside the through holes. The design of the connection holes on the connecting plate facilitates fixation with the idler bearing seat through bolts, simplifying the installation process and improving the connection reliability, ensuring that the idler does not loosen or shift during movement and adjustment.

[0012] Furthermore, the lifting mechanism includes chain hoists arranged at equal intervals along the length direction of the crossbeam. The upper hooks of the chain hoists are connected to the bottom of the crossbeam through steel wires, and the lower hooks of the chain hoists are connected to the top of the sliding plate through steel wires. The structure of the chain hoists in cooperation with the steel wires realizes the smooth lifting and lowering of the connecting mechanism through symmetric arrangement, facilitating the operator to accurately adjust the height of the idler, and at the same time avoiding the problem of large space occupation of traditional hoisting equipment, meeting the installation requirements in fully restricted spaces.

Detailed implementation manners

[0014] The present invention will be further described below in conjunction with embodiments. The purpose is only to better understand the content of the present invention. Therefore, the examples given do not limit the protection scope of the present invention.

[0015] An idler insertion device in a fully restricted space includes a chassis frame 1. One side of the bottom of the chassis frame 1 is provided with a set of tires. A positioning frame 2 is arranged at the top of the chassis frame 1 and on the side where the tires are located. A connecting mechanism for connecting the idler 8 is slidably connected longitudinally in the positioning frame 2, and a lifting mechanism is arranged between the top of the positioning frame 2 and the connecting mechanism.

[0016] Further, the positioning frame 2 includes a pair of vertical columns 2-1. A cross beam 202 is arranged between the tops of the vertical columns 2-1. A chute is arranged between the opposite surfaces of the vertical columns 2-1. The connecting mechanism is slidably connected in the chute. The design of the chute provides stable guiding support for the connecting mechanism, which not only ensures the overall rigidity of the device but also realizes the smooth lifting of the connecting mechanism.

[0017] Further, a diagonal brace 3 is arranged between the vertical column 2-1 and the chassis frame 1, which enhances the structural strength of the positioning frame 2, effectively disperses the load stress during the hoisting process, and improves the stability of the device during the translation and lifting of the idler 8.

[0018] Further, the connecting mechanism includes a sliding plate 4 that slides along the chute between the vertical columns 2-1. A connecting plate 5 opposite to the middle of the sliding plate 4 is arranged outside the chassis frame 1. A sleeve 6 is arranged between the sliding plate 4 and the connecting plate 5. Through holes opposite to the sleeve 6 are opened on the sliding plate 4 and the connecting plate 5, which can adapt to the size change of the transmission shaft of the idler 8, ensure stable connection, and at the same time facilitate the quick disassembly and assembly with the bearing seat of the idler 8, improving the construction efficiency.

[0019] Further, the inner diameter of the sleeve 6 is larger than the outer diameter of the transmission shaft of the idler 8 to be installed, ensuring that the transmission shaft can pass through smoothly.

[0020] Further, connection holes are opened on the connecting plate 5 and outside the through holes. The design of the connection holes on the connecting plate 5 facilitates fixation with the bearing seat of the idler 8 through bolts, which not only simplifies the installation process but also improves the connection reliability, ensuring that the idler 8 will not loosen or shift during movement and adjustment.

[0021] Furthermore, the lifting mechanism includes chain hoists 7 arranged equidistantly along the length direction of the cross beam 202. The upper hook of the chain hoist 7 is connected to the bottom of the cross beam 202 through a steel wire rope, and the lower hook of the chain hoist 7 is connected to the top of the sliding plate 4 through a steel wire rope. The structure of the chain hoist 7 cooperating with the steel wire rope realizes the stable lifting of the connecting mechanism through symmetric arrangement, which is convenient for the operator to accurately adjust the height of the idler 8. At the same time, it avoids the problem of large space occupation of traditional hoisting equipment and meets the installation requirements of all restricted spaces.

[0022] First, the transmission shaft of the idler 8 penetrates into the sleeve 6 and is fixedly connected to the bearing seat of the idler 8 through bolts. Using the tire on one side of the chassis frame 1 as a fulcrum, the other end of the chassis frame 1 is pressed manually to form a lever effect to transport the idler 8 in the restricted space. When the idler 8 is relatively heavy, the power moment can be increased by placing counterweights on the trolley chassis frame 1. After transporting it to the installation location, one end of the idler 8 is lifted and adjusted to a horizontal state. Subsequently, operate the lifting mechanism at the top of the positioning frame 2, and drive the connecting mechanism to lift smoothly along the chute of the positioning frame 2 through the chain hoist 7 to adjust the height position of the idler 8. After the height of the idler 8 is adjusted in place, push the chassis frame 1 to make the tire roll, driving the idler 8 to move horizontally to the installation position. By finely adjusting the levelness of the lifting mechanism and the chassis frame 1, the idler 8 is inserted into the installation foundation or frame. Finally, remove the connecting bolts to complete the installation of the idler 8.
