Detailed Description

The technical solution of the present invention will be further explained with reference to the accompanying drawings and embodiments.

As shown in fig. 1-4, to improve the efficiency of opening and closing the cover plate of the installation of the protective device for hoisting a wellhead. The utility model provides a hoist and mount well head safety device, including mount 1, the movable block 5 and the apron 7 that one end articulated on movable block 5 that set up in mount 1 through the vertical removal of lead screw 2 and guide bar 3, the both sides of the 7 other ends of apron all are provided with connecting rod 8, still including setting up in guide rail 9 and the baffle 11 that sets up in guide rail 9 of 1 both sides of mount, baffle 11 and guide rail 9 parallel arrangement are provided with between baffle 11 and the guide rail 9 and carry out horizontal spacing limit structure to baffle 11, the expansion end of connecting rod 8 rotates to be connected on baffle 11.

The method comprises the following steps of arranging a fixed frame 1 at one side of a hoisting wellhead, arranging two guide rails 9 at the opposite sides of the other group of hoisting wellhead, wherein the fixed frame 1 is a rectangular frame, arranging an adjusting motor 4 at the top of the fixed frame 1, and coaxially and fixedly connecting an output shaft of the adjusting motor 4 with the top end of a lead screw 2; the moving block 5 is connected to the lead screw 2 in a threaded fit manner, and the guide rod 3 penetrates through the moving block 5; when the cover plate 7 is in a horizontal state, the cover plate 7 completely covers the hoisting wellhead.

Through adjusting motor 4 drive lead screw 2 and rotate, make movable block 5 along lead screw 2's axial rebound, movable block 5 drives its articulated end rebound with apron 7 at the in-process of rebound, because the other end of apron 7 passes through connecting rod 8 and is connected with baffle 11, at the in-process that apron 7 was promoted by movable block 5, the one end that apron 7 was provided with connecting rod 8 moves in the horizontal direction all the time, and then make the contained angle of apron 7 and horizontal plane increase progressively, finally realize apron 7 and promote nearly vertical state (nevertheless apron 7 can not be in vertical state), finally realize hoisting the complete opening of well head.

As shown in fig. 1-4, to achieve the horizontal position limitation of the baffle 11. Guide rail 9 is the channel-section steel that the opening upwards set up, limit structure for rotate set up in the gyro wheel 10 of baffle 11 bottom, the axis of rotation of gyro wheel 10 is located guide rail 9's inside. By arranging the roller 10, the sliding friction of the baffle 11 is changed into rolling friction, and the resistance of the baffle 11 moving on the guide rail 9 is reduced; the diameter of the roller 10 is set so that the roller 10 is difficult to be released from the opening at the top of the guide rail 9, thereby improving the stability of the baffle 11. The cover plate 7 is pulled upwards by the moving block 5 and upwards supports the connecting rod 8, the movable end of the connecting rod 8 is rotatably arranged at the bottom of the baffle plate 11, the connecting rod 8 can be subjected to radial force, so that no bearing is arranged between the connecting rod 8 and the baffle plate 11 for connection, and the baffle plate 11 can be matched with the connecting rod 8 through an increasing shaft sleeve.

As shown in fig. 1-4, in order to increase the service life of the cover plate 7. The protection device comprises two fixing frames 1 which are arranged in mirror symmetry and are provided with corresponding cover plates 7, connecting rods 8, guide rails 9, baffles 11 and limiting structures. When the area of a hoisting wellhead is large, a cover plate 7 with a large area needs to be arranged, the cover plate 7 is supported through the connecting rods 8 and the moving blocks 5, when the dead weight of the cover plate 7 is large, the hinged end of the cover plate 7 and the moving blocks 5 and the connecting rods 8 are prone to bending, or the body of the cover plate 7 is prone to bending due to uneven stress; sealing of a large-area hoisting wellhead is thus achieved by the provision of two cover plates 7.

As shown in fig. 1-2, to facilitate removal of dust from the slots in the top of the guide rails 9. A gap is arranged between the opposite ends of the guide rails 9 arranged on the two sides of the two mirror-symmetrical fixed frames 1. When the cover plate 7 is lifted to be close to the vertical state, the baffle plate 11 moves to the separated ends of the guide rails 9, and dust in the guide rails 9 can be scraped to the gaps through the gaps between the two groups of the opposite ends of the guide rails 9.

As shown in fig. 1 and 3. The end part of the cover plate 7 is provided with a connecting seat 12, two ends of the connecting seat 12 are respectively positioned in the two connecting rings 6 on the side wall of the moving block 5, and two ends of the connecting seat 12 are cylindrical rod pieces. The cylindrical rod members at the two ends of the connecting base 12 are respectively inserted into the two connecting rings 6 on the side wall of the moving block 5, so that the connecting base 12 can rotate in the connecting rings 6, and the end part of the cover plate 7 is hinged to the side wall of the moving block 5.

In a preferred embodiment of the present invention, the weight of the cover plate 7 is further reduced. The cover plate 7 is of a hollow structure, and a grating plate serving as a reinforcing rib is arranged in the cover plate. By means of the built-in grating plate, on the premise that the strength of the cover plate 7 is maintained, the material inside the cover plate 7 is introduced, and further the weight of the cover plate 7 is reduced.

As the utility model discloses preferred embodiment, for avoiding apron 7 to be hoisted by the movable block 5 is vertical, causes the separation of baffle 11 and guide rail 9, and then unable realization hoist and mount well head safety device's automatic re-setting. The length of the cover plate 7 is larger than the linear distance from the top end of the lead screw 2 to the guide rail 9.
