Embodiment Construction
[0019] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.
[0020] like figure 1 , figure 2 As shown, the preferred embodiment of the present invention includes a base 1, a column 2, a reading sliding block 3, and a ruler frame 5.
[0021] Specifically, if image 3 As shown, the base 1 is used to be placed on the lower web of the hot-rolled J-type forklift mast channel 8 to provide a measurement reference. Preferably, the base 1 is block-shaped, such as a rectangular parallelepiped, with a flat bottom surface, so as to be placed horizontally in the channel steel 8 .
[0022] The lower end of the column 2 is fixed on the base 1 by means of welding, fastener connection or clamping. Preferably, the upright column 2 is an elongated plate-shaped structure, and scale lines are provided on the sides of the upright column 2 along its length direction. Further, two vertical edges on the sides of ...

A hot-rolled J-shaped forklift gantry channel steel lower leg height measuring tool includes: a pedestal used for being placed on a lower web plate of hot-rolled J-shaped forklift gantry channel steel to provide a measuring reference; a stand column whose lower end is fixed on the pedestal and which is provided with scale lines along a length direction; two reading sliding blocks which are used for pointing to the scale lines of the stand column, are symmetrically arranged on two sides of the stand column and are slidably arranged on the stand column; and two ruler frames whose upper ends are fixed on the reading sliding blocks respectively and lower ends are horizontal flat surfaces to be used for abutting against two leg end faces of the hot-rolled forklift gantry channel steel. The hot-rolled J-shaped forklift gantry channel steel lower leg height measuring tool provided by the invention can measure the height of two lower legs of the J-shaped forklift gantry channel steel at the same time, and calculate a height difference between the two lower legs in one step, thereby reducing measuring errors, and improving measuring efficiency.
Description
technical field [0001] The invention relates to a steel rolling equipment, in particular to a tool for measuring the height of the lower leg of a hot-rolled J-type forklift mast channel steel. Background technique [0002] The channel steel of the forklift mast is used to make the mast of the forklift. During assembly, the channel steel of the forklift mast of various specifications is installed together, and the guide wheels are installed in the inner groove. In order to ensure the stable lifting of the fork, the high dimensional accuracy of the lower legs needs to be guaranteed, and in order to ensure consistency, the difference between the heights of the two lower legs must also be controlled within the tolerance range. During the hot rolling process of the channel steel of the J-type forklift mast, due to the asymmetric shape of the channel steel of the J-type forklift mast, the height of the lower leg needs to be measured under the cooling bed. The base of the ordinary ...
