Detailed Description
In order to enable those skilled in the art to better understand the technical solutions of the present application, the technical solutions of the present application are further described below with reference to the accompanying drawings and examples.
Referring to the drawings 1-9, an adjustable elevator well mouth protecting device convenient for construction engineering ground construction is provided with side support rods 1 symmetrically fixed with two sides of a well mouth, a protecting net 2 is arranged between the symmetrical side support rods 1, the side support rods 1 can be fixed with the wall surface by drilling holes on the wall body outside the well mouth at present, and after the side support rods 1 are fixed with the wall surface, shielding protection of the well mouth can be realized by the protecting net 2.
In order to avoid dismantling the protection device during secondary construction of the ground in the later stage, secondary construction operation of the ground is not influenced, the application sets the side support rod 1 into a lifting structure, the height of the side support rod and the protection net 2 can be lifted during secondary construction of the ground, interference on secondary construction of the ground is solved, meanwhile, the side support rod 1 and the protection net 2 can be prevented from being dismantled under the lifting state, and further, the wellhead is still kept protected effectively during secondary construction of the ground.
In order to solve the problem that the wall surface is damaged due to the fact that the protection device is fixed with the wall surface through multiple times of drilling, a protection locking mechanism assembled with a wellhead is further arranged on the side supporting rod 1, the locking and fastening of the opposite side supporting rod 1, the protection net 2 and the wellhead can be achieved through the wellhead structure, and the defect that multiple times of drilling on the wall surface are needed is overcome.
Specifically, as shown in fig. 2, the side supporting rod 1 is divided into an upper supporting rod 11 and a lower supporting rod 12, an adjusting cylinder 3 penetrating the lower supporting rod 12 is arranged at the bottom of the upper supporting rod 11, and corresponding adjusting holes a are formed in both the lower supporting rod 12 and the adjusting cylinder 3. The whole protection device is fixed with a wellhead through the upper supporting rod 11, as shown in fig. 3-4, when the ground secondary construction is carried out, the lower supporting rod 12 is lifted up, the bottom end of the lower supporting rod is separated from contact with the ground, then a ground construction space (shown as b in fig. 4) is reserved, after adjustment, a pin is inserted into an adjusting hole a corresponding to the lower supporting rod 12 and the adjusting cylinder 3, and further the ground secondary construction operation can be realized on the basis of not disassembling the protection device.
Preferably, as shown in fig. 2, the protection net 2 is divided into an upper net body 21 and a lower net body 22 which are fixedly connected with the upper supporting rod 11 and the lower supporting rod 12 respectively, and an adjusting gap 2a is reserved between the upper net body 21 and the lower net body 22. When the upward movement adjustment of the lower support rod 12 is performed, the lower net body 22 moves upward together, the upward movement of the lower net body 22 can be smoothly realized by adjusting the gap 2a, and meanwhile, the upper net body 21 and the lower net body 22 form effective protection of the whole wellhead face together.
Specifically, as shown in fig. 5-7, the protection locking mechanism is a locking rod 4 vertically arranged on each upper supporting rod 11 towards the inner side of the wellhead, and a locking screw 5 capable of propping against the side wall of the wellhead is arranged on each locking rod 4 in a penetrating manner. When the protection device is assembled, the lock rod 4 at each side extends into the wellhead along the side wall of the wellhead, and the upper support rod 11, the upper net body 21, the lower support rod 12, the lower net body 22 and the wellhead are fixed by screwing the locking screw 5 and propping against the side wall of the wellhead, so that the problem that holes are needed to be punched when the protection device is fastened with the wellhead at present is effectively solved. In the assembled and fastened state, when the ground secondary construction is needed, after the support rod 12 is lifted up to a proper height, the pin is inserted into the adjusting hole a corresponding to the lower support rod 12 and the adjusting cylinder 3, so that the ground secondary construction operation can be realized on the basis of not disassembling the protecting device.
In order to further improve the tightness of the assembly of the protection device with the wellhead, as shown in fig. 8-9, a limit rod 6 corresponding to the inner wall of the wellhead is vertically hinged at the inner end of each lock rod 4. Preferably, the hinge part of the limiting rod 6 is provided with a torsion spring, when the assembly is carried out, the acting force of the torsion spring is overcome, so that the limiting rod 6 is in a vertical state, the limiting rod 6 and the locking rod 4 penetrate into the inner wall of the wellhead, after penetrating into the inner side of the wellhead, the limiting rod 6 is loosened, and the limiting rod rotates towards the direction of the inner wall of the wellhead under the action of the torsion spring and corresponds to the inner wall of the wellhead, in this state, (with the upper supporting rod 11 and the lower supporting rod 12) the displacement of the protecting device, which is vertical to the wellhead, can be limited, and the falling of the protecting device and the wellhead under the action of external force is avoided. And when dismantling, because the thickness of well head wall is not big, operating personnel accessible arm passes from protection network 2, drives gag lever post 6 rotatory to vertical state, can outwards dismantle protector and well head.
The principle of the application is as follows: when the protection operation is carried out, the upper supporting rod 11 and the lower supporting rod 12 are adjusted to the maximum length through the adjusting hole a, then the limiting rod 6 is driven to rotate to the vertical state by manually overcoming the acting force of the torsion spring, then the limiting rod 6 and the locking rod 4 penetrate into the inner wall of the wellhead, after penetrating into the inner side of the wellhead, the limiting rod 6 is loosened, and rotates towards the direction of the inner wall of the wellhead under the action of the torsion spring and corresponds to the inner wall of the wellhead, and in the state, the supporting rod 1 at the same side can limit the displacement of the protection device, which is vertical to the wellhead, front and back.
When the ground is secondarily constructed, after the pin is drawn out, the lower support rod 12 is lifted up, the bottom end of the lower support rod is separated from contact with the ground, a ground construction space is reserved, after adjustment, the pin is inserted into the adjusting hole a corresponding to the lower support rod 12 and the adjusting cylinder 3, and further, the secondary construction operation on the ground can be realized on the basis of not disassembling the protecting device.
And when dismantling, because the thickness of well head wall is not big, operating personnel accessible arm passes from protection network 2, drives gag lever post 6 rotatory to vertical state, can outwards dismantle protector and well head.
The foregoing has outlined and described the basic principles, main features and advantages of the present application. Various changes and modifications may be made to the present application without departing from the spirit and scope of the application, and such changes and modifications fall within the scope of the application as hereinafter claimed.
