Problems solved by technology

[0002] In the process of dismantling the roll ring on site, it may happen that the pressure of pulling the roll ring reaches the limit due to the excessive pressure when installing the roll ring, and finally the roll ring cannot be pulled out, or the tapered sleeve ear cannot be pulled out when the roll ring is pulled out. Condition of the roller ring;
[0003] In such an emergency situation where the roll ring cannot be pulled out or the roll ring cannot be pulled out directly with a puller, it is difficult to use general disassembly tools, and the roll box can only be removed as a whole, and the operator needs to transfer the roll box as a whole to the pre-assembly workshop The use of large-scale machinery for dismantling, or even dismantling the roller rings seriously affects the production rhythm; therefore, an emergency tool for removing online roller rings is needed to solve on-site emergencies

Embodiment 1

[0019] Embodiment 1: as figure 1 , 2 A kind of emergency tool that facilitates online dismantling of the roll collar shown in and 3, the emergency tool is fixedly installed on the end of the roller shaft 14, and the emergency tool includes a working plate 6, a support plate 3, a traction screw 1, and adjusting Screw rod 7 and jack 13, described working board and 6 supporting boards 3 are all provided with four positioning through holes 10 and 12, working board 6 and supporting board 3 are connected into a whole by four traction screw rods 1, working board 6 It is arranged below the support plate 3, the center of the working plate 6 is provided with a roller ring fixing hole 9, the working plate 6 is composed of two positioning plates 15 of the same size, and the bottom of the supporting plate is provided with Jack 13, said jack 13 is installed directly above the roller ring fixing hole 9.

Embodiment 2

[0020] Embodiment 2: as figure 1 , 2 As shown in and 3, the positioning plate 15 is provided with a transverse through hole 11, and the adjusting screw 7 is movably installed in the transverse through hole 11, and the two positioning plates 15 are connected into one by the adjusting screw 7 in the transverse through hole 11. Overall; the working plate 6 is divided into two parts from the middle, which is convenient for installation on roller rings of different sizes. The main function of the adjustment screw 7 is to facilitate the opening of the fixing hole 9 of the roller ring, which facilitates the fixing and positioning of the roller ring 5. The connection is tight and convenient. Disassembly work of roller ring 5.

Embodiment 3

[0021] Embodiment 3: as figure 1 , 2 As shown in and 3, the upper and lower sides of the working plate 6 are provided with lock nuts 2 connected to the draw screw 1, and the upper and lower sides of the support plate 3 are provided with lock nuts 2 connected to the draw screw 1; The left and right ends of the support plate 3 described in the invention are provided with locking nuts 8 connected to the adjusting screw 7; Nut 2, the connection between the screw rod and the two plates is stable, which improves the stability of the disassembly work.

Abstract

The invention discloses an emergency tool for facilitating dismounting a roller ring on line. The emergency tool comprises a working plate, a supporting plate, traction screws, a regulating screw and a jack; four locating through holes are formed in each of the working plate and the supporting plate which are connected into a whole through the four traction screws; the working plate is arranged below the supporting plate; a roller ring fixing hole is formed in the center of the working plate; the working plate is composed of two locating plates with the same size; and the bottom of the supporting plate is provided with the jack mounted right above the roller ring fixing hole. Two parts of the working plate is directly fixed together with the roller ring, and then, a working surface for fixing the roller ring is pulled out by supporting the jack by taking a roller shaft of a rolling mill and the supporting plate as supporting points, so that the roller ring which cannot be directly pulled out can be rapidly pulled out, and the emergency tool is labor-saving and efficient.

Description

technical field [0001] The invention relates to the field of disassembly and assembly equipment for steel rolling equipment, in particular to an emergency tool for convenient online disassembly of roll rings. Background technique [0002] In the process of dismantling the roll ring on site, it may happen that the pressure of pulling the roll ring reaches the limit due to the excessive pressure when installing the roll ring, and finally the roll ring cannot be pulled out, or the tapered sleeve ear cannot be pulled out when the roll ring is pulled out. Condition of the roller ring; [0003] In such an emergency situation where the roll ring cannot be pulled out or the roll ring cannot be pulled out directly with a puller, it is difficult to use general disassembly tools, and the roll box can only be removed as a whole, and the operator needs to transfer the roll box as a whole to the pre-assembly workshop The use of large-scale machinery for dismantling, or even dismantling t...
