Example 2

Based on embodiment 1, a small spring 6 is sleeved between the large spring 5 and the mandrel 7.

Example 3

Based on example 2, the natural extension lengths of the large spring 5 and the small spring 6 are identical.

Example 4

Based on the embodiment 1, the outer cylinder 2 and the front end of the large spring 5 are fixed on the base 1, and the base 1 is sleeved on the mandrel 7.

Example 5

According to the embodiment 1, the outer cylinder 2 is provided with the guide pin 3, and the length of the guide pin 3 is not less than that of the outer cylinder 2.

Example 6

According to embodiment 1, the rear end of the mandrel 7 is coaxially provided with a roller 11 through a roller shaft 12.

Example 7

In embodiment 6, the roller 11 is provided with the lateral force correcting plate 10.

Example 8

Based on embodiment 1, the surface of the lateral force correcting plate 10 contacting the roller 11 is a multi-angle surface.

Example 9

Based on embodiment 1, the rear end of the mandrel 7 is provided with a top cover 9, and the top cover 9 is detachably fixed through a locking screw 8.

Example 10

Based on the above embodiment, the device comprises a base 1, an outer cylinder 2, a guide pin 3, an inner cylinder 4, a large spring 5, a small spring 6, a mandrel 7, a locking screw 8, a top cover 9, a lateral force correcting plate 10, a roller 11 and a roller shaft 12; the inner cylinder 4 penetrates through the outer cylinder 2; the guide pins 3 are arranged on two sides of the inner cylinder 4; the mandrel 7 penetrates through the inner barrel 4 and is fixed and limited by the top cover 9; the top cover 9 is connected with the inner barrel 4 through a bolt; the roller 11 is arranged on the top cover 9 through a roller shaft 12; the large spring 5 and the small spring 6 are arranged in the inner cylinder 4, and the small spring 6 passes through the mandrel 7; the outer cylinder 4 is connected with the base 1 through bolts; the top cover 9 and the outer cylinder 3 are locked by a locking screw 8; the lateral force correcting plate 10 is installed on the erecting device and is in line contact with the roller 11, and the roller 11 rolls on the lateral force correcting plate when erecting.

The transmission of force is achieved by means of rollers 11 and lateral force correction plates 10.

The surface of the lateral force correcting plate 10, which is in contact with the rolling wheel 11, is a multi-angle surface, so that the lateral force of the erecting device on the device during erecting and returning can be reduced.

The power storage compensation capacity is increased by adopting a mode of combining a large spring 5 and a small spring 6;

the spindle 7 penetrates the base all the time when the spring is in a free state and in a compressed state.

Guide grooves are formed in two sides of the outer cylinder 2, guide pins 3 are arranged on two sides of the inner cylinder 4, and the guide pins 3 slide in the guide grooves, so that the relative rotation of the inner cylinder and the outer cylinder during sliding can be prevented;

when the locking screw 8 is adopted for locking, the loss compensation function can be realized;

a typical operating principle is as follows:

1) Firstly, a base needs to be arranged on a fixed part of a erecting device, a lateral force correcting plate needs to be arranged on the erecting part of the erecting device, and a locking screw of the device is taken down;

2) When the device works, the locking screw is not installed, the erecting device is leveled back, and the lateral force correction plate is driven to bring a lateral force to the left lower part of the roller wheel, so that the large spring and the small spring are compressed, the force accumulation is realized, and when the erecting device is leveled back in place, the force accumulation is finished;

3) In the force accumulation state, an upward thrust is applied to the erecting device, and the thrust can compensate the erecting force, so that the erecting force is reduced;

4) Along with the upward erection of the erecting device, the spring is gradually extended, and the output compensating force is gradually reduced until the roller wheel is separated from the lateral force correcting plate;

5) When the lateral force correcting plate does not need to work, the locking screw rod is installed in the power storage state, and the locking screw rod is screwed down to enable the roller and the lateral force correcting plate to be separated from contact.
