Referring to fig. 1, for the utility model discloses a well head prevents weighing down safety device, including lock ring 1 with prevent weighing down net 11, lock ring 1 is the annular setting, lock ring 1's external diameter and well head diameter looks adaptation prevent weighing down net 11 and install in lock ring 1's inner circle to make prevent weighing down net 11 and form the circular with well head looks adaptation. Be provided with a plurality of supporting component 2 on the inside wall of well head, a plurality of supporting component 2 are along the circumference evenly distributed of well head, and the lock ring 1 is supported in well head department by a plurality of supporting component 2 to make lock ring 1 be located the below of well lid, thereby will prevent weighing down that net 11 evenly lays well head department again, prevent weighing down and can not appear great space between net 11 and the well head lateral wall, thereby improved the safety protection effect to the pedestrian.
Referring to fig. 2, the support assembly 2 includes a mounting plate 21, the mounting plate 21 is disposed along a vertical direction, the mounting plate 21 is located below the support ring 1, and the mounting plate 21 abuts against a side wall of the wellhead along a radial direction of the support ring 1 and is mounted on the side wall of the wellhead by using two fixing members. The fixing elements are expansion bolts 22, and two expansion bolts 22 are arranged at intervals along the axial direction of the support ring 1. Two expansion bolts 22 are used to fix the mounting plate 21 on the side wall of the wellhead, so that the mounting plate 21 is convenient for positioning and installation.
Referring to fig. 2, a supporting plate 23 is fixedly arranged at the top end of the mounting plate 21, the supporting plate 23 is arranged along the horizontal direction, the supporting plate 23 is perpendicular to the mounting plate 21, and the bottom surface of the support ring 1 abuts against the supporting plate 23. The supporting plates 23 in the plurality of supporting assemblies 2 are uniformly distributed below the circumference of the supporting ring 1, and the distribution provides supporting force for the supporting ring 1, so that the supporting ring 1 is stably arranged at a well head. Two reinforcing ribs 24 are arranged between the support plate 23 and the mounting plate 21, the two reinforcing ribs 24 are arranged at intervals, and the expansion bolt 22 is positioned between the two reinforcing ribs 24, so that the connection strength of the support plate 23 and the mounting plate 21 is increased, the support ring 1 is supported more stably, and the installation of the expansion bolt 22 is not interfered.
Referring to fig. 1 and 2, the top surface of one end of the mounting plate 21, which is far away from the side wall of the wellhead, is also provided with a locking assembly 3, and the locking assembly 3 is used for locking the support ring 1 on the support plate 23, so that after the anti-falling net 11 receives impact, the shaking range of the support ring 1 along with the anti-falling net 11 is reduced, and the stability and the safety of the support ring 1 and the anti-falling net 11 are improved.
Referring to fig. 3, the locking assembly 3 includes a fixing block 31 fixedly disposed on the top surface of the mounting plate 21, the fixing block 31 is disposed along the height direction, and the distance between the fixing block 31 and the sidewall of the wellhead is adapted to the width of the support ring 1. The top end of the fixed block 31 is provided with a sleeve 32, and the bottom end of the sleeve 32 is inserted into the fixed block 31 and is rotatably connected with the fixed block. The outer peripheral surface of sleeve 32 sets firmly locking lever 33, and locking lever 33 sets up along the radial of sleeve 32, and the one end that locking lever 33 kept away from fixed sleeve 32 points to the well head lateral wall, makes lock ring 1 be located the below of locking lever 33, and lock ring 33 is held against to the top surface of lock ring 1.
The locking bar 33 exerts a downward pressure on the support ring 1, thereby clamping the support ring 1 between the locking bar 33 and the support plate 23 and locking the support ring 1. Referring to fig. 4, when a worker needs to enter the inspection well, the worker only needs to rotate the locking rod 33 to enable the locking rod 33 to be separated from the upper side of the support ring 1, and after the support ring 1 loses the limit of the locking rod 33, the support ring 1 can be lifted upwards, and the anti-falling net 11 can be taken out from the wellhead.
