[0056] Another technical problem to be solved by the present invention is a method for using a construction fence protection device:

[0057] S1. Grab the object to be grasped in the first area: start the first electric cylinder to move the grasping substrate downward as a whole, and after the grasping substrate is moved to the top of the object to be grasped, then start the second electric cylinder and the third electric cylinder, so that the second electric cylinder pushes the first grasping plate, and the third electric cylinder pushes the second grasping plate, so that the first grasping plate and the second grasping plate are close to each other, so as to grasp the object to be grasped;

[0058] S2, transferring the grasping member from the first area to the second area: turning on the first driving motor so that the driving wheel drives the driven wheel to rotate, so as to drive the entire cross arm to move along the length direction of the adjustment base, so that the cross arm transfers from the first area to the second area, and at the same time, turning on the second driving motor so that the connecting screw rotates, so as to drive the entire sliding plate to move in the front-to-back direction, so as to change the position of the entire grasping member in the front-to-back direction;

[0059] S3, reinforcement operation of the left support arm and the right support arm as a whole: first, the reinforcement frame is sleeved on the left support arm and the right support arm, and the first inserted screw is sequentially passed through the left support arm, and the first nut is screwed to fit with the reinforcement frame, and the second nut is screwed to fit with the reinforcement frame, and the third inserted screw is sequentially passed through the right support arm, and the third nut is screwed to fit with the reinforcement frame, and the fourth nut is screwed to fit with the reinforcement frame, so that multiple sets of grounding plates are grounded, and the buried bolts are screwed into the ground to strengthen the contact between the left support arm and the right support arm as a whole and the ground, and at the same time, it can prevent the inner supporting substrate from being impacted by the object to be grasped, causing the left support arm and the right support arm to be unstable as a whole;

[0060] S4, buffering the falling object to be grasped onto the inner supporting substrate: when the object to be grasped falls onto the anti-falling buffer component, it first contacts and buffers with the rubber plate. Since the plug plate is in the initial state, the plug plate does not contact the buffer airbag. Therefore, when the falling object to be grasped continues to move downward, the plug plate is compressed to move downward, and the buffer spring is squeezed to perform a primary buffering. After the plug plate continues to move downward, the plug plate continues to move downward and is squeezed onto the buffer airbag to perform a secondary buffering operation.

[0061] S5. Linkage operation for stabilizing the ground-inserting component as a whole: after the buffer airbag is squeezed, since the buffer airbag is connected to the fourth electric cylinder, the buffer airbag is inflated into the fourth electric cylinder, so that the output end of the fourth electric cylinder outputs, so that the fourth electric cylinder pushes the lower plate to descend, and at the same time, the ground-inserting component as a whole penetrates into the ground, so as to strengthen the contact between the fence body and the left support arm and the right support arm and the ground, and can prevent the object to be grasped from falling and causing the left support arm and the right support arm to be unstable as a whole;

[0062] S6. Use of the ground insert: After the output end of the fourth electric cylinder is output, the ground insert will be moved downward as a whole. First, the first plug is inserted into the ground. Since the first plug, the second plug, and the third plug are gradually reduced, the ground penetration force of the first plug is improved at the beginning of the ground penetration, and the ground penetration force of the second plug and the third plug is gradually reduced, and the penetrated soil can stay on the straight edges of the first plug, the second plug, and the third plug in turn, and the triangular side plugs can be used to conduct secondary soil guidance to assist the use of the first plug.

[0063] In general, compared with the prior art, the above technical solution conceived by the present invention has the following beneficial effects:

[0064] The construction fence protection device of the present invention and the method of using the same can transfer the grabbing member from the first area to the second area or from the second area to the first area through the arranged adjusting member, and can grab the object to be grabbed in the first area through the arranged grabbing member. The reinforcement machine frame is firstly sleeved on the left support arm and the right support arm through the arranged protective reinforcement member, and the first inserted screw is passed through the left support arm in turn, and then the first nut is screwed to fit with the reinforcement machine frame, and the second screw is screwed to tighten the second screw. The cap is fitted with the reinforcement frame, the third inserted screw is passed through the right support arm in sequence, the third nut is screwed to fit with the reinforcement frame, and the fourth nut is screwed to fit with the reinforcement frame, so that multiple sets of grounding plates are grounded, and the buried bolts are screwed into the ground to strengthen the contact between the left support arm and the right support arm as a whole and the ground, and at the same time, it can prevent the inner supporting base plate from being impacted by the object to be grasped, causing the left support arm and the right support arm to be unstable as a whole. Through the arranged anti-drop buffer component, when the object to be grasped falls to the anti-drop buffer When the plug plate is on the impact member, it first contacts with the rubber plate for buffering. Since the plug plate is in the initial state, it does not contact the buffer airbag. Therefore, when the dropped object to be grasped continues to move downward, the plug plate is compressed to move down, and the buffer spring is squeezed to perform a primary buffering operation. After the plug plate continues to move downward, the plug plate continues to move downward and squeezes the buffer airbag to perform a secondary buffering operation. Through the arranged stable plug-in member, after the buffer airbag is squeezed, the buffer airbag and the fourth electric The cylinders are interconnected, so the buffer airbag is inflated into the fourth electric cylinder to enable the output end of the fourth electric cylinder to output, so that the fourth electric cylinder pushes the lower plate to descend, and at the same time, the ground insert is penetrated into the ground as a whole to strengthen the contact between the fence body and the left support arm and the right support arm and the ground, and to prevent the objects to be grasped from falling and causing the left support arm and the right support arm to become unstable as a whole. By arranging the ground insert, the contact force between the fence body as a whole and the ground can be further strengthened. BRIEF DESCRIPTION OF THE DRAWINGS

[0084] The present invention is based on an overall idea that, through the arranged adjustment member 2, the grasping member 3 can be transferred from the first area to the second area or from the second area to the first area, and the grasping member 3 can be arranged to grasp the object to be grasped in the first area, and through the arranged protection reinforcement member 4, the reinforcement frame 41 is firstly sleeved on the left support arm 11 and the right support arm 12, and the first insertion screw 42 is passed through the left support arm 11 in turn, and the first nut 43 is screwed to fit with the reinforcement frame 41, and the second nut 44 is screwed to fit with the reinforcement frame 41.

[0100] Another technical problem to be solved by the present invention is a method for using a construction fence protection device:

[0101] S1. Grab the object to be grasped in the first area: start the first electric cylinder 31 to move the grasping base plate 32 downward as a whole. After the grasping base plate 32 is moved to the top of the object to be grasped, then start the second electric cylinder 33 and the third electric cylinder 36, so that the second electric cylinder 33 pushes the first grasping plate 35, and the third electric cylinder 36 pushes the second grasping plate 38, so that the first grasping plate 35 and the second grasping plate 38 are close to each other, so as to grasp the object to be grasped;

[0102] S2, the grabbing member 3 is transferred from the first area to the second area: the first driving motor 231 is turned on, so that the driving wheel 232 drives the driven wheel 235 to rotate, so as to drive the cross arm 22 to move along the length direction of the adjustment base 21 as a whole, so that the cross arm 22 is transferred from the first area to the second area, and at the same time, the second driving motor 26 is turned on, so that the connecting screw 27 is rotated, so as to drive the sliding plate 28 to move along the front-back direction as a whole, so as to change the position of the grabbing member 3 as a whole in the front-back direction;

[0103] S3, reinforcement operation of the left support arm 11 and the right support arm 12 as a whole: first, the reinforcement frame 41 is sleeved on the left support arm 11 and the right support arm 12, and the first inserted screw 42 is passed through the left support arm 11 in sequence, and the first nut 43 is screwed to fit with the reinforcement frame 41, and the second nut 44 is screwed to fit with the reinforcement frame 41, and the third inserted screw 45 is passed through the right support arm 12 in sequence, and the third nut 46 is screwed to fit with the reinforcement frame 41, and the fourth nut 47 is screwed to fit with the reinforcement frame 41, so that the multiple sets of grounding plates 49 are grounded, and the buried bolts 491 are screwed to penetrate into the ground to strengthen the contact between the left support arm 11 and the right support arm 12 as a whole and the ground, and at the same time, it can prevent the inner supporting substrate 13 from being impacted by the object to be grasped, causing the left support arm 11 and the right support arm 12 to be unstable as a whole;

[0104] S4, buffering the falling object to be grasped onto the inner supporting substrate 13: when the object to be grasped falls onto the anti-falling buffer member 5, it first contacts and buffers with the rubber plate 55. Since the inserting plate 54 is in the initial state, the inserting plate 54 is not in contact with the buffer airbag 52. Therefore, when the falling object to be grasped continues to move downward, the inserting plate 54 is compressed to move downward, and the buffer spring 58 is squeezed to perform a primary buffering. After the inserting plate 54 continues to move downward, the inserting plate 54 continues to move downward and is squeezed onto the buffer airbag 52 to perform a secondary buffering operation.

[0105] S5. Linkage operation for stabilizing the ground-inserting member 7 as a whole: after the buffer airbag 52 is squeezed, since the buffer airbag 52 is connected to the fourth electric cylinder 72, the buffer airbag 52 is inflated into the fourth electric cylinder 72, so that the output end of the fourth electric cylinder 72 is output, so that the fourth electric cylinder 72 pushes the lower plate 73 to descend, and at the same time, the ground-inserting member 78 is penetrated into the ground as a whole, so as to strengthen the contact between the fence body 1 and the left support arm 11 and the right support arm 12 and the ground, and can prevent the object to be grasped from falling and causing the left support arm 11 and the right support arm 12 to be unstable as a whole;

[0106] S6. Use of the ground inserting member 78 for penetrating the ground: After the output end of the fourth electric cylinder 72 is output, the ground inserting member 78 will be moved downward as a whole, and first, the first plug 782 is inserted into the ground. Since the first plug 782, the second plug 783, and the third plug 784 are gradually reduced, the ground penetrating force of the first plug 782 is improved at the beginning of the ground penetration, and the ground penetrating force of the second plug 783 and the third plug 784 is gradually reduced, and the penetrated soil can stay on the straight edges of the first plug 782, the second plug 783 and the third plug 784 in turn, and the triangular side plugs 785 can be used to conduct the soil for the second time to assist the use of the first plug 782.
