AI Technical Summary
In small spaces, the installation and adjustment of the strut bolts are difficult, especially due to the limitations of the narrow space, which causes the hammer wrench to fail to generate sufficient impact force, and it is easy to cause damage to the sensor cable during the adjustment process.
The torque multiplier and the jacking frame are used to support the torque multiplier through the support tube and screw, extend the torque input to the outside of the opening, and adjust it with an electric wrench to avoid the torque multiplier disengagement and damage to the sensor cable.
The adjustment process of pillar bolts is simplified, labor intensity is reduced, work efficiency is improved, and safety is ensured.

Abstract
Description
Technical Field
[0001] The utility model relates to a large moment force regulating device used in a small space. Background Art
[0002] like Figure 3 As shown, the lower frame is a steel structure that can withstand a weight of more than 4,000 tons. To ensure sufficient strength and rigidity, the lower frame is welded from dense ribs and ribs. Support bolts for adjusting the height of the thrust pad and the force are designed and installed between the ribs. A single bolt is large in size and weight, and can withstand a weight of at least 225 tons.
[0003] Currently, the pillar bolts are installed in the narrow space formed by the ribs and the ribs, which makes the installation and adjustment of the pillar bolts very difficult. Currently, a hammer wrench is used for adjustment. On the one hand, the hammer wrench is restricted by the ribs on both sides of the pillar bolts, resulting in a very small hammer swing distance, which often fails to form sufficient impact force. On the other hand, since the pillar bolts are installed from bottom to top, the staff needs to hold the wrench upwards when hammering the wrench. If they are not careful, the wrench will slip or fall and break the sensor cable connected to the pillar bolt. Utility Model Content
[0004] The utility model aims to provide a large moment force regulating device used in a small space, which is used to solve the problem of difficulty in adjusting the support bolts.
[0005] In order to solve the above problems, the technical solution of the utility model is:
[0006] A large moment force regulating device for use in a small space comprises a torque multiplier and a lifting frame, wherein the lifting frame comprises a support tube, nuts are welded on both sides of the support tube, screws are assembled in the nuts, the screws are lifted on the torque multiplier, and a first notch is opened at the lower end of the support tube.
[0007] Two second notches are provided at the lower end of the support tube.
[0008] Also included is a sheath that is sleeved outside the torque multiplier.
[0009] The beneficial effects of the utility model are as follows: a torque multiplier is used to extend the torque input end of the support bolt outside the opening, and an electric wrench is used to twist the support bolt, so that the twisting angle of the support bolt is not limited by the rib plate, and a support tube is used to support the torque multiplier to prevent the torque multiplier from falling during use, to prevent the sensor cable from breaking, and to prevent the torque multiplier from disengaging and slipping, so that the support bolt is simple and safe to adjust, which reduces the labor intensity of workers and improves work efficiency.

[0015] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0016] like Figure 1 As shown, a large torque force regulating device for small space includes a torque multiplier 1 and a lifting frame, wherein the lifting frame includes a support tube 5, nuts 4 are welded on both sides of the support tube 5, screws 3 are assembled in the nuts 4, the screws 3 are lifted on the torque multiplier 1, and a first notch 6 is opened at the lower end of the support tube 5. The torque multiplier 1 uses the ASBZ-4 torque multiplier 1 produced by "Elson Asen Fastening System Company", and the torque input end and the torque output end of the torque multiplier 1 are located at both ends of the multiplier; when in use, after the torque multiplier 1 is assembled on the pillar bolt 3, the lifting frame is inserted into the opening, and the sensor on the pillar bolt 3 is passed through the first notch 6, and then the screw 3 is rotated to make the upper end of the screw 3 support the torque multiplier 1 to support the torque multiplier 1, and then the electric wrench is docked with the torque multiplier 1, and the pillar bolt 3 is adjusted by jogging the electric wrench.
[0017] Two second notches 7 are provided at the lower end of the support tube 5. The two second notches 7 are used to snap into the housing to prevent the support tube 5 from falling.
[0018] It also includes a sheath 2 that is sleeved outside the torque multiplier 1. When in use, the sheath 2 is placed in the gap between the torque multiplier 1 and the opening, and the sheath 2 is used to protect the torque multiplier 1 to prevent the opening from squeezing the torque multiplier 1 and causing damage to the multiplier.
[0019] The above embodiments are only preferred technical solutions of the present invention and should not be regarded as limitations of the present invention. The protection scope of the present invention shall be the technical solutions recorded in the claims, including equivalent replacement solutions of the technical features in the technical solutions recorded in the claims.
