Problems solved by technology

[0003] At present, the pre-embedding of the foundation bolts of the base of the existing vertical rolling mill mainly adopts the following methods: the bolts are pre-embedded by conventionally hanging the vertical and horizontal center lines to control the elevation. This method is very prone to inaccurate bolt pre-embedding, Drooping and offset, and the work intensity is high and the work efficiency is low, which cannot meet the production needs

Embodiment 1

[0035] Such as figure 1 and figure 2 As shown, the embodiment of the present application provides a pre-embedded device for foundation bolts of a vertical rolling mill base, which includes a vertically arranged positioning frame 100, two positioning plates 110 and a lifting device for driving the positioning frame 100 up and down. The positioning plates 110 are arranged in sequence along the length direction of the positioning frame 100 and are configured to be movable along the length direction of the positioning frame 100. Each positioning plate 110 is provided with two bolt positioning bar holes arranged at intervals up and down and running through its two sides. 120. Wherein, the positioning frame 100 is composed of two vertical plates 101 arranged up and down and two horizontal plates 102 arranged left and right. The bottom is bent upwards to form a chute 140, the top and bottom of the two positioning plates 110 are respectively slid in the upper chute 130 and the chut...

Embodiment 2

[0039] Such as image 3 As shown, the embodiment of the present application provides a vertical rolling mill base anchor bolt pre-embedded device, which has roughly the same structure as the vertical rolling mill base anchor bolt pre-embedded device provided in Example 1. The difference is that in this embodiment The pre-embedded device for the foundation bolts of the vertical rolling mill base also includes a first telescopic rod 150. The first telescopic rod 150 includes a first threaded rod 151 and a first threaded cylinder 152 threaded on one end of the first threaded rod 151. Both ends of a telescoping rod 150 are detachably connected to the two positioning plates 110 via connecting bolts.

[0040] The pre-embedded device for anchor bolts at the base of the vertical rolling mill provided in this embodiment can quickly and efficiently locate and fix multiple groups of bolts at fixed intervals along the horizontal direction. The operator first rotates the first threaded rod...

Embodiment 3

[0042] Such as Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, the embodiment of the present application provides a vertical rolling mill base anchor bolt pre-embedded device, which has roughly the same structure as the vertical rolling mill base anchor bolt pre-embedded device provided in Example 2, the difference is that in this embodiment Each positioning plate 110 is connected with two vertical adjustment plates 190 that can move along the bolt positioning bar hole 120, and the vertical adjustment plate 190 is provided with a bolt positioning hole 200, and the bolt positioning hole 200 is used to pass through it. The bolts pass through the corresponding bolt positioning strip holes 120, and each vertical adjustment plate 190 is respectively protruded with a bump 191 that slides and engages with the bolt positioning strip holes 120, and the bolt positioning holes 200 pass through the corresponding bumps 191; Each vertical adjustment plate 190 is connected with ...

Abstract

The invention discloses a vertical rolling mill base foundation bolt pre-embedding device and relates to the field of positioning devices. The vertical rolling mill base foundation bolt pre-embedding device comprises a vertically-arranged positioning frame, at least two positioning plates and a lifting device used for driving the positioning frame to ascend and descend, and the positioning plates are sequentially arranged in the length direction of the positioning frame and are configured to move in the length direction of the positioning frame. Each positioning plate is provided with at least one bolt positioning strip-shaped hole which extends in the vertical direction and penetrates through the two sides of the positioning plate. The vertical rolling mill base foundation bolt pre-embedding device provided in the embodiment can help operators to quickly and efficiently position and pre-embed foundation bolts of a vertical rolling mill.

Description

technical field [0001] The present application relates to the field of positioning devices, in particular to a pre-embedded device for foundation bolts of a vertical rolling mill base. Background technique [0002] The installation of rolling line equipment requires the precise pre-embedding of the anchor bolts of the rolling mill base. The rolling mill is divided into a horizontal rolling mill and a vertical rolling mill. The vertical rolling mill is different from the horizontal rolling mill in that the base anchor bolts are all constructed on the horizontal plane, and the anchor bolts are pre-buried on the side walls of the vertically arranged concrete archway. [0003] At present, the pre-embedding of the foundation bolts of the base of the existing vertical rolling mill mainly adopts the following methods: the bolts are pre-embedded by conventionally hanging the vertical and horizontal center lines to control the elevation. This method is very prone to inaccurate bolt p...
