When the pump is installed and lowered into the pump well, one connecting piece 3 is fixedly connected to the pump through the bow shackle, one ends of the two hoisting steel cables 2 are fixedly connected to the connecting piece 3 through the bow shackle, the next connecting piece 3 is fixedly connected to the other ends of the two hoisting steel cables 2 through the bow shackle, the end part of the hoisting rope of the crane is fixedly connected to the connecting piece 3 through the bow shackle, and then the hoisting rope is lowered through the crane so that the hoisting steel cables 2 hoist the pump and gradually lowered into the pump well. After the lifting steel cable 2 is completely lowered into the pump well, a lever is inserted into the connecting piece 3 connected with the lifting rope of the crane, the lever penetrates through the through hole 4 in the connecting piece 3, the connecting piece 3 is clamped on another object through the lever to fix the position of the pump, then the next section of lifting steel cable 2 is continuously connected and fixed on the clamped connecting piece 3, then the operation is repeated until the pump is mounted and lowered into the appointed position in the pump well, finally the turnbuckle 15 is connected onto the connecting piece 3, the connecting piece 3 and the lifting steel cable 2 are lifted through the turnbuckle 15, and the turnbuckle 15 is adjusted to compensate the lifting steel cable 2 and the connecting piece 3, so that the pump can reach the appointed position in the pump well more accurately.
As shown in fig. 2, 3 and 4, the connecting piece 3 is further provided with a clamping component 5 to clamp and fix the cable of the pump, and the clamping component 5 clamps and fixes the cable to prevent the cable from being twisted by force to be wound and knotted. The connecting piece 3 is provided with two first L-shaped holes 12 with the same height in parallel, the first L-shaped holes 12 are in an L shape in vertical arrangement, the clamping assembly 5 comprises a fixing plate 7 with one side face abutting on the connecting piece 3, the fixing plate 7 is an epoxy resin plate, a pressing plate 6 abuts on one side face of the fixing plate 7 back to the connecting piece 3, two fixing bolts 8 with the same height are arranged on the pressing plate 6 in a penetrating mode, the fixing bolts 8 penetrate through the fixing plate 7 and the connecting piece 3, the fixing bolts 8 penetrate through the first L-shaped holes 12 on the connecting piece 3, a supporting piece 13 is arranged on the portion, penetrating through the first L-shaped holes 12, of the fixing bolts 8, two second L-shaped holes 16 with the same height in parallel are arranged on the supporting piece 13, the fixing bolts 8 penetrate through the second L-shaped holes 16, a flat washer 9 and a spring washer 10 are sequentially sleeved on the portion, the fixing bolts 8 are connected with the fixing nuts 11 in a threaded mode, and a split pin 14 penetrating through the fixing nuts 11 is clamped after the fixing bolts 8 are connected with the fixing nuts in a threaded mode to prevent the fixing nuts from loosening and falling off the fixing nuts 11.
The cable of pump is fixed by the centre gripping between clamp plate 6 and fixed plate 7 when fixed, because fixed plate 7 is the epoxy board, epoxy has certain elasticity for the cable can be fixed better, also prevents clamp plate 6 and fixed plate 7 clamp bad cable when the centre gripping cable simultaneously. The supporting piece 13 has the function of limiting, when the supporting piece 13 is positioned in the pump well, smaller gaps exist between the two ends of the supporting piece 13 and the inner wall of the pump well, so that the supporting piece 13 can be abutted to the inner wall of the pump well for limiting when the lifting steel cable 2 shakes, and damage caused by pump swing impact of the lowest end to the inner wall of the pump well due to overlarge swing amplitude of the lifting steel cable 2 is avoided.
When the cable is fixed by the clamping assembly 5, the fixing bolt 8 passes through the end position with the higher height of the first L-shaped hole 12, the clamping assembly 5 is moved again after the cable is fixed, so that the fixing bolt 8 of the clamping assembly 5 moves to the end position with the lower height of the first L-shaped hole 12, the original cable is equal to the lifting steel cable 2 in length, but after the clamping assembly 5 is moved, the cable corresponding to each section of the lifting steel cable 2 is longer than the lifting steel cable 2, a certain margin remains loose, when the lifting steel cable 2 and the cable are placed in a pump well, the cable is affected by low temperature, the lifting steel cable 2 and the cable shrink to different degrees, the set margin enables the lifting steel cable 2 and the cable to remain loose after the cable is shrunk, and the lifting steel cable 2 and the cable are prevented from being shorter than the lifting steel cable 2 and being pulled by the cable to support and lift the pump after the cable is shrunk, and the cable is prevented from being pulled and the cable is protected.
In order to facilitate the disassembly of the support 13 and the clamping assembly 5, the aperture sizes of one ends of the first L-shaped hole 12 and the second L-shaped hole 16 are set to be larger than the diameters of the flat washer 9, the spring washer 10 and the fixing nut 11. When the support piece 13 is disassembled, the cotter pin 14 is extracted, then the fixing nut 11 is unscrewed, and then the support piece 13 is moved, so that the flat washer 9, the spring washer 10 and the fixing nut 11 move to one end with larger aperture of the second L-shaped hole 16, and the three parts can directly pass through the second L-shaped hole 16, thereby facilitating the disassembly of the support piece 13. Similarly, the clamping assembly 5 and the fixing bolt 8 are moved, so that the flat washer 9, the spring washer 10 and the fixing nut 11 are moved to the larger end of the first L-shaped hole 12, and can directly penetrate through the first L-shaped hole 12, and the clamping assembly 5 is convenient to detach. Also, since the fixing nut 11 does not need to be removed at the time of disassembly, only the fixing nut 11 needs to be screwed at the time of installation instead of reinstallation, the clamping assembly 5 and the supporting member 13 are conveniently installed.
The present embodiment is only for explanation of the present invention and is not to be construed as limiting the present invention, and modifications to the present embodiment, which may not creatively contribute to the present invention as required by those skilled in the art after reading the present specification, are all protected by patent laws within the scope of claims of the present invention.
