Problems solved by technology

[0003] The purpose of the intelligent tensioning trolley provided by the present invention is to overcome the negative bending moment tensioning of the T beam in the prior art. Because there is no intelligent tensioning trolley, the single-beam manual tensioning process is generally used, which makes the installation of the jack inconvenient and unsafe. , the problem of low efficiency; the second purpose is to overcome the large error in the manual control of tension control in the prior art, the high requirements for workers’ technical experience, proficiency, and sense of responsibility, and the difficulty of monitoring and management; the third purpose is to overcome the problems of manual control of tension The elongation measurement is inaccurate, and it is difficult to achieve dual control of tension and elongation

Embodiment 1

[0027] An intelligent tensioning trolley includes a truss unit, a walking unit, a lifting unit and a control unit, the bottom of the truss unit is connected to the walking unit, the top of the truss unit is connected to the lifting unit, and the control unit is connected to the lifting unit.

Embodiment 2

[0029] An intelligent tensioning trolley includes a truss unit, a walking unit, a lifting unit and a control unit, the bottom of the truss unit is connected to the walking unit, the top of the truss unit is connected to the lifting unit, and the control unit is connected to the lifting unit.

[0030] The walking unit moves the intelligent tensioning trolley above the negative bending moment to be stretched, installs the jack on the lifting unit and connects it to the control unit, and the control unit controls the lifting unit to move the jack down to the tensioning place of the negative bending moment and install it in place , to carry out symmetrical intelligent overall tensioning at both ends; using intelligent tensioning, the jack is placed in place by the intelligent tensioning trolley, saving time and effort, convenient operation, high efficiency, and good safety; intelligent tensioning can accurately monitor and control stress and elongation Quantity, timely check elonga...

Embodiment 3

[0032] Such as Figure 1-3 As shown, an intelligent tensioning trolley for T-beam negative moment mid-beam includes a truss unit, a walking unit, a lifting unit and a control unit. The bottom of the truss unit is connected to the walking unit, the top of the truss unit is connected to the lifting unit, and the control unit is connected to lift unit.

[0033] The truss unit includes an upper frame body 1, a lower frame body 2, a middle frame body 11 and a plurality of vertical beams 3, and the upper layer frame body 1, the middle layer frame body 11 and the lower layer frame body 2 are sequentially connected by a plurality of vertical beams 3 from top to bottom , the middle frame body 11 and the lower frame body 2 all include left vertical beam 4, right vertical beam 5 and a plurality of cross beams 6, the left vertical beam 4 is horizontally symmetrically connected to the right vertical beam 5 through a plurality of cross beams 6, and the upper layer frame body 1 is a Crossbe...

Abstract

The invention belongs to the technical field of machinery and particularly relates to an intelligent stretching trolley. The stretching trolley includes a truss unit, a walking unit, a lifting unit and a control unit. The bottom of the truss unit is connected with the walking unit, the top of the truss unit is connected with the lifting unit, the control unit is connected with the lifting unit, and the problems are solved that since traditional T-shaped girder hogging moment stretching often adopts a single-bundle manual stretching process, it is inconvenient to install a jack, the safety level is low, the efficiency is low, the control error during manual operation of a stretching force is large, the difficulty degree of monitoring management is high, measurement of the elongation amountis not precise, and double control of the stretching force and the elongation amount is difficult. By adopting an intelligent stretching mode, the jack is put in position through the intelligent stretching trolley, time and strength are saved, the operation is convenient, the efficiency is high, and the safety level is high. The manual stretching process is successfully substituted, intelligent control is achieved, overall intelligent stretching is achieved without influences of mankind and environmental factors, stretching control factors such as stop points, a loading speed rate and load holding time all meet requirements of bridge design and technical construction specifications, and convenience is provided for management and control.

Description

technical field [0001] The invention belongs to the technical field of machinery, and in particular relates to an intelligent tensioning trolley. Background technique [0002] Traditional T-beam negative moment tensioning is not equipped with an intelligent tensioning trolley, and the single-beam manual tensioning process is generally used, so the installation of the jack is inconvenient, unsafe, and low in efficiency; the manual control of the tension control has large errors and requires workers with technical experience. , Proficiency, high sense of responsibility requirements, difficult monitoring and management. Moreover, the elongation measurement is not accurate, and it is difficult to achieve dual control of tension and elongation. With intelligent tensioning, the jack is placed in place by the intelligent tensioning trolley, which saves time and effort, is convenient to operate, high in efficiency, and good in safety; intelligent tensioning can accurately monitor a...
