Detailed Description
The rollover prevention device of the gutless workover rig comprises two groups of guide square boxes 1, telescopic arms 2, connecting seats 3, connecting plates 4, reinforcing tie bars 5, horizontal oil cylinders 6, vertical oil cylinders 7 and bearing heads 8 (see the attached figures 1 and 2 in the specification).
Two groups of guide square boxes 1 which are symmetrically arranged are welded into an integral structure (see the attached figure 2 in the specification); the upper surfaces of the two groups of guide square boxes 1 are symmetrically welded with connecting seats 3; the upper end of the connecting seat 3 is fixedly provided with a reinforcing lacing wire 5 through a bolt; one end of the reinforcing lacing wire 5 is vertically welded with a connecting plate 4 (see the attached figure 1 in the specification); the lower end of the connecting plate 4 is fixedly connected with the connecting seat 3 through a connecting bolt. When the anti-rollover device is assembled, the anti-rollover device can be fixedly arranged on a chassis of the tension-rope-free workover rig through the connecting plate 4 and the bolts, and forms an integral structure with the workover rig.
The guiding square box 1 is internally inserted with a telescopic arm 2 (see the attached figure 1 of the specification). A horizontal oil cylinder 6 is hinged in the guide square box 1 at one side of the telescopic arm 2; the end of a piston rod of the horizontal oil cylinder 6 is hinged with the telescopic arm 2; when the horizontal oil cylinder 6 works, the telescopic arm 2 can be driven to move back and forth along the inside of the guide square box 1 (see the attached figure 1 in the specification).
The telescopic arms 2 in the group of guide square boxes 1 extend out of the guide square boxes 1 from one end and then are fixedly provided with vertical oil cylinders 7; the bottom end of a piston rod of the vertical oil cylinder 7 is provided with a bearing head 8; the telescopic arm 2 in the other group of the guide square boxes 1 extends out of the guide square boxes 1 from the other end and is fixedly provided with a vertical oil cylinder 7; the bottom end of a piston rod of the vertical oil cylinder 7 is provided with a bearing head 8 (refer to the attached figures 1 and 2 in the specification); the vertical oil cylinder 7 can drive the bearing head 8 to move up and down when working.
The pressure-bearing head 8 consists of a pressure-bearing plate 9, an assembling annular plate 10, a connecting ball seat 11 and a connecting ball head 12; the bottom end of a piston rod of the vertical oil cylinder 7 is welded with a connecting ball head 12; the connecting ball head 12 is movably provided with a connecting ball seat 11 through an assembling annular plate 10 and an assembling bolt; the bottom end of the connecting ball seat 11 is welded with a bearing plate 9 (see the attached figures 3 and 4 of the specification). The purpose of thus arranging the pressure-bearing head 8 is: so that bearing plate 9 can be through linking up 11 movable mounting in the piston rod bottom of perpendicular hydro-cylinder 7 of ball seat to make perpendicular hydro-cylinder 7 drive bearing plate 9 and move down, contradict the in-process with ground, bearing plate 9 can carry out self-control according to ground shape, makes it can contact with ground laminating, and then has avoided ground not level, and when bearing plate 9 contacted with ground emergence point, damaged bearing plate 9's problem took place.
The bearing plate 9 is a circular plate (see the attached figure 5 in the specification). Because the rollover prevention device is arranged on the chassis of the workover rig, and the internal space of the chassis is limited, the area of the pressure bearing plate 9 is smaller, when the rollover prevention device is contacted with the ground, the ground is easily fractured due to the smaller area of the pressure bearing plate 9, so that the rollover prevention device loses the ground support; in order to solve the problem, people often place sleepers with large areas on the ground, so that the bearing plates 9 act on the ground through the sleepers, the problem that the bearing plates 9 are prone to fracturing the ground is solved, and when the bearing plates 9 are arranged to be circular plates, the sleepers can evenly transmit supporting force to the vertical oil cylinders 7 through the circular plates, and the problem that the vertical oil cylinders 7 are unreasonably stressed when the bearing plates 9 are in other states is avoided.
As an improvement of the utility model; the bearing plate 9 is composed of an extension side plate 13, a support middle plate 14 and a fixing bolt 15 (see the attached figures 6, 7 and 8 in the specification); a middle supporting plate 14 is welded at the bottom end of the connecting ball seat 11; the end heads at the two ends of the middle supporting plate 14 are respectively movably provided with an extension side plate 13 through a rotating pin and a torsion spring. Under the effect of torsional spring elasticity, extend sideboard 13 and have the trend that folds each other and draw close all the time, consequently when perpendicular hydro-cylinder 7 is the shrink state, extend sideboard 13 and be "folding" state (see description attached figure 7), so extend after sideboard 13 is folding, will reduce the space to the problem of "conflict" takes place for extending sideboard 13 and workover rig chassis has been avoided.
The upper parts of the two end heads of the middle supporting plate 14 are symmetrically and movably provided with fixing bolts 15 through guide seats 16; a fixed socket 17 is welded on the extending side plate 13 at one side of the fixed bolt 15; the fixed plug 15 is intermittently connected with the fixed socket 17 in a plugging way. The fixed bolt 15 is in a T-shaped structure; the fixed bolt 15 is movably connected with the guide seat 16; a limit pin 18 (refer to the figure 8 in the specification) is welded on the fixing bolt 15 on one side of the guide seat 16. The purpose of thus improving the pressure bearing plate 9 is to: when the bearing plate 9 is in a working state, the extension side plate 13 can be kept in a horizontal state with the middle support plate 14 under the matching of the fixing bolt 15 and the fixing socket 17, so that the stress area of the extension side plate can be effectively increased when the extension side plate is in contact with the ground, and the problem that a sleeper needs to be added in an auxiliary mode when the bearing plate 9 is a round plate is avoided.
The rollover prevention device is fixedly arranged on a chassis of the non-guy rope workover rig through a connecting plate 4 and a bolt. When the non-guy wire workover rig is in a non-working state, the horizontal oil cylinder 6 and the vertical oil cylinder 7 are both in a contraction state, and the extension side plate 13 of the bearing plate 9 is in a folding state (see the attached figure 7 in the specification).
When the non-guy rope workover rig is in a working state, the horizontal oil cylinder 6 is started to drive the telescopic arm 2 to extend to the longest state along the guide square box 1; then manually overturning the extension side plate 13 to enable the extension side plate to be kept in a horizontal state with the support middle plate 14, and pushing the fixing plug pin 15 to enable the fixing plug pin to be connected with the corresponding fixing socket 17 in an inserting mode; thus, the extending side plate 13 and the supporting middle plate 14 can be fixedly connected to form an integral structure; and then starting the vertical oil cylinder 7 to drive the bearing head 8 to move downwards to keep a supporting state with the ground, and closing the vertical oil cylinder 7. Thus, the anti-rollover device can form support at two sides of the non-guy rope workover rig through the pressure bearing heads 8; thereby playing the role of preventing side turning.
When the non-guy rope workover rig is converted from the working state to the non-working state, the fixing bolt 15 is reset at first, and the extension side plate 13 is restored to the folded state under the action of the torsion spring; and then after the vertical oil cylinder 7 and the horizontal oil cylinder 6 are reset in sequence, the anti-rollover device can enter the next working cycle.
The anti-rollover device of the non-guyed workover rig is compact in structure and ingenious in design, and can support the non-guyed workover rig through the supported pressure-bearing head, so that the potential safety hazard problem that the vehicle is prone to rollover when encountering severe natural environment (strong wind) in the operation process due to the fact that the non-guyed workover rig is not provided with the ground pile type wind-borne guyed rope can be effectively solved; the requirement of safe production and use of enterprises is met.
