Description

Technical Field

[0001] The present application relates to the technical field of construction equipment, and in particular to a device for preventing columns from collapsing on a second-floor platform. Background Art

[0002] The second-level platform of the derrick is the main equipment for placing the vertical roots during the construction of petroleum engineering. During the conventional drilling operation, the derrick workers or manipulators need to operate on the second-level platform to stand each column of drilling tools in the derrick. Since the existing second-level platform lacks protective devices, during the drilling operation, when the derrick workers open the hanging card to pull the drilling tools into the finger beam, if they are not fixed in time or the drilling tools are pushed into the stopper frame by mistake, the drilling tools will pop out from the entrance of the finger beam of the second-level platform and enter the derrick. At the same time, the traveling block in the derrick is often in an up and down movement state during the drilling operation. When the moving traveling block parts press down or get stuck on the overturned drilling tools, there is a risk of causing safety accidents. Therefore, there is an urgent need for a second-level platform anti-column outward collapse device to prevent the drilling tools from accidentally popping out and overturning. Utility Model Content

[0029] The upper surface of the first fixed plate 1 is fixedly connected with a fixed shaft 13, and a baffle assembly 2 is installed on the fixed shaft 13. The baffle assembly 2 is arranged at the bottom of the second fixed plate 3. The baffle assembly 2 includes a fixed connecting plate 21 and a baffle 24. The connecting plate 21 is hinged on the fixed shaft 13, and a groove 23 is opened on the connecting plate 21.

[0030] A spring 4 is arranged outside the inner end of the connecting plate 21, and the other end of the spring 4 is fixedly connected to the fixing block 11. Specifically, a fixing piece 5 is arranged on the connecting plate 21 and the fixing block 11, and both ends of the spring 4 are connected to the fixing piece 5, which is convenient for disassembly.

[0031] The fixing block 11 is used to connect the first fixing plate 1 and the second fixing plate 3, and the first fixing plate 1 and the second fixing plate 3 can constitute a box body for storing the baffle assembly 2; the connecting plate 21 and the baffle 24 are an integrated structure, constituting the baffle assembly 2, the spring 4 is used to provide a reset elastic force for the baffle assembly 2, and the fixing part 5 is used to install the spring 4.

[0032] In addition, a plurality of first mounting holes 12 are formed on the fixing block 11 , and third mounting holes 31 are formed on the second fixing plate 3 at positions corresponding to the first mounting holes 12 . The first mounting holes 12 and the third mounting holes 31 are used for installing screws for fixing.

[0033] The articulation of the connecting plate 21 and the fixed shaft 13 can be achieved in the following manner:

[0034] A second mounting hole 22 is formed on the connecting plate 21 , and a bearing 6 is fixedly connected in the second mounting hole 22 , and the bearing 6 is fixedly connected to the fixed shaft 13 . Both the second mounting hole 22 and the fixed shaft 13 are used to install the bearing 6 , thereby realizing the rotation of the baffle assembly 2 .

[0035] The first fixing plate 1 is provided with a first through hole 14 and a second through hole 15, and the first through hole 14 is arranged on the relatively inner side of the baffle 24, and the second through hole 15 is arranged on the relatively outer side of the baffle 24; a third through hole 33 is provided on the second fixing plate 3 at a position corresponding to the first through hole 14, and a fourth through hole 34 is provided on the second fixing plate 3 at a position corresponding to the second through hole 15; a plug 7 is inserted into the fourth through hole 34, and one end of the plug 7 is inserted into the second through hole 15.

[0036] The first through hole 14, the second through hole 15, the third through hole 33 and the fourth through hole 34 are all used to accommodate the latch 7. When the drilling is started, the latch 7 is inserted into the third through hole 33 and the first through hole 14. When the drilling is lowered, the latch 7 is inserted into the fourth through hole 34 and the second through hole 15.

[0037] A limiting block 32 is fixedly connected to the lower surface of the second fixing plate 3 at a position corresponding to the fixing shaft 13 , and the limiting block 32 is disposed on one side of the bearing 6 , and is used to limit the bearing 6 .

[0038] The working principle of the above-mentioned second-floor platform anti-column outward collapse device is as follows:

[0039] When in use, the device is installed at the front end of the side of the monkey platform. When the drilling operation is carried out, the pipe string needs to be inserted but not exited, so the latch 7 is inserted into the first through hole 14 through the third through hole 33. The derrick worker can pull the drill string into the monkey platform and release his hands when drilling. When the driller makes a gesture to lower the traveling carriage, the baffle 24 fixes the pipe string in the monkey platform by the connecting plate 21 and the latch 7, and the pipe string will not fall out of the monkey platform. When the drilling operation is carried out, the baffle 24 is rotated to retract it into the box body formed by the first fixing plate 1 and the second fixing plate 3, and the latch 7 is inserted into the second through hole 15 through the fourth through hole 34 (such as Figure 1 As shown), the device is attached to one side of the monkey platform and does not affect the normal use of the monkey platform.

[0040] Among them, the first mounting hole 12 on the fixing block 11 is used to cooperate with the third mounting hole 31 to install the screw, the fixing shaft 13 and the second mounting hole 22 are both used to install the bearing 6, the limit block 32 is used to limit the bearing 6, the bearing 6 is used to assist the rotation of the connecting plate 21, the groove 23 on the connecting plate 21 is used to accommodate the pin 7, the spring 4 is used to provide a reset elastic force for the baffle assembly 2 so that it can automatically reset, thereby realizing the self-closing function, and the fixing part 5 is used to install the spring 4; when the spring 4 needs to be replaced, the baffle assembly 2 is in the reset state, and the part hanging the spring 4 will be exposed outside the first fixing plate 1, which is convenient for direct replacement without disassembly of the second fixing plate 3, and maintenance is simpler and more convenient.

[0041] Compared with the prior art, the above-mentioned second-floor platform column anti-collapse device has the following advantages:

[0042] The spring is used to provide a restoring elastic force for the baffle assembly, so that the drill is automatically closed after entering the finger beam, avoiding the situation where the drill is dumped out of the second-layer platform, improving construction safety, and the application can free the hands of the operator, so that the operator can quickly make gestures to guide the operation, effectively improving the operation efficiency;

[0043] In addition, the baffle assembly in the device is convenient for replacing the spring, and the connecting plate is provided with a groove for accommodating the latch, so that the surface contact is achieved during the impact, which can reduce the pressure generated by the impact pressure of the baffle on the latch, and the baffle is stored between the two fixed plates, which is convenient for use in the second-layer table position where it is inconvenient to rotate and store to the outside;

[0044] The device has the advantages of simple structure, convenient maintenance and strong practicality.
