As shown in figures 1, 2, 3, 4 and 5, the novel counter weight does not need special personnel to manually observe the centering position between the counter weight and the pile foundation. Before the work, the staff links together two fixed plates of fixed establishment through connecting plate 3 with screw nut, because two fixed plates 1 can make things convenient for the dismouting combination, accomodate for carrying like this and all brought the facility with the use. After the two fixing plates 1 are fixed (located at the upper end of the pile foundation at the moment), the worker adjusts the handles 5 of the four locking screw rods 2 clockwise or anticlockwise respectively according to needs, so that the four locking screw rods 2 move forwards or backwards along the screw holes 101 respectively, and in short, the supporting plates 4 on the inner sides of the four locking screw rods 2 are adjusted to be in close contact with the upper end of the periphery of the pile foundation respectively (a fixing mechanism can be installed when the lifting equipment leaves the ground just before the pile foundation is erected). After the installation, the fixing mechanism and the like are preferably located about 1 meter below the upper end of the pile foundation, and then workers respectively adjust the angles of the detecting heads of the four photoelectric switches U2, U3, U4 and U5 towards the upper end, so that the inner diameter of a detection area formed by infrared beams emitted by the detecting heads of the four photoelectric switches U2, U3, U4 and U5 is smaller than the outer diameter of the lower end of the heavy hammer; when the angles of the detecting heads of the photoelectric switches U2, U3, U4 and U5 towards the upper end are adjusted, firstly, the manual screw 61 is loosened, the front and back pitch angles of the photoelectric switches U2, U3, U4 and U5 are adjusted in place respectively, then the manual screw 61 is screwed respectively, and the photoelectric switches U2, U3, U4 and U5 are not moved any more; when the upward angles of the detecting heads of the four photoelectric switches are adjusted, the four photoelectric switches U2, U3, U4 and U5 are adjusted towards the outer side end vertically, so that the inner diameter of a detection area formed by emitted infrared beams is large, the four photoelectric switches U2, U3, U4 and U5 are adjusted towards the inner side end vertically, so that the inner diameter of the detection area formed by the emitted infrared beams is small, the specific adjustment can be carried out according to the outer diameter of the heavy hammer, and the angle is adjusted in advance by a worker according to operation experience (after the worker adjusts the angle of the photoelectric switches for the first time and uses the photoelectric switches, the photoelectric switches are fixed, so that the positions of the four photoelectric switches are not required to be adjusted any more, convenience is brought to a user, under the actual condition, the inner diameter of the detection area formed by the infrared beams emitted by the four photoelectric switches U2, U3, U4 and U5 detecting heads is too large, so that the periphery of the lower ends of the heavy hammer cannot be effectively detected, the inner diameter of a detection area formed by infrared beams emitted by the four photoelectric switches U2, U3, U4 and U5 detection heads is too small, so that the lower end of the detection heavy hammer is deviated to one direction, that is, the outer diameter of the detection area formed by the infrared beams emitted by the four photoelectric switches U2, U3, U4 and U5 detection heads cannot cover the lower end of the heavy hammer, the heavy hammer can be used for carrying out heavy hammer on the upper end of the pile foundation at an angle in the follow-up process, and the upper end of the pile foundation of the heavy hammer cannot be fully covered from top to bottom, so that a good heavy hammer effect cannot be achieved). When the detection range of the four photoelectric switches U2, U3, U4 and U5 is adjusted, the operation under a heavy hammer is not needed, the heavy hammer can be transversely placed on the ground in advance, then the fixing mechanism and the like are placed on the ground at certain intervals, the detection heads of the four photoelectric switches U2, U3, U4 and U5 are respectively vertically or obliquely aligned to the periphery of the lower end of the heavy hammer (the side end of the heavy hammer at the moment) within a certain distance (for example, the detection range of the four photoelectric switches U2, U3, U4 and U5 is 5 meters), the fixing mechanism is installed at the upper end of a pile foundation after the detection heads of the four photoelectric switches U2, U3, U4 and U5 are adjusted, and the operation is more convenient and the adjusting effect is better.

As shown in fig. 1, 2, 3, 4, and 5, the angle of the photoelectric switch is adjusted, after the power switch S is turned on by the operator, the wireless receiving circuit module U1 is in an electrified working state, and the operator (which may be an operator of the heavy hammer device) presses the first wireless signal transmitting button S1 of the portable wireless transmitting circuit module U7, so that the wireless transmitting circuit module U7 transmits the first wireless closing signal. After the wireless receiving circuit module U1 receives the first path of wireless closing signal, 4 pins of the wireless receiving circuit module U1 can output high level (2, 5, 6 and 7 pins are suspended) and then the high level is subjected to voltage reduction and current limitation through the resistor R1 to enter the base electrode of an NPN triode Q1, the NPN triode Q1 conducts a collector and outputs low level to enter the negative power supply input end of a relay K, the relay K is electrified to attract the control power supply input end and a normally open contact end of the relay K to be closed, and then four sets of photoelectric switches U2, U3, U4, U5 and wireless transmitting circuit module U6 are in the working state that gets electricity (press the first button of wireless transmitting circuit module U7 again, it launches the wireless open circuit signal of the first way, and then, 4 feet of wireless receiving circuit module U1 stop to output high level, relay K loses the electricity, then four sets of photoelectric switches U2, U3, U4, U5 and wireless transmitting circuit module U6 just also can lose the electricity and no longer work, reached wireless non-contact control purpose). When the heavy hammer operator does not operate the heavy hammer to reach the front of the upper end of the pile foundation, that is, for example, within a range of 5 meters from top to bottom, the infrared light beams emitted by the emission heads of the four sets of photoelectric switches U2, U3, U4 and U5 are not shielded, 3 pins of the four sets of photoelectric switches U2, U3, U4 and U5 do not output high levels. When a heavy hammer operator operates the heavy hammer to reach the upper end of the pile foundation (other lifting equipment firstly enables the pile foundation to reach the position where the pile foundation is located and vertically distributes the heavy hammer), namely, when infrared beams emitted by the emitting heads of one or more sets of photoelectric switches U2, U3, U4 and U5 are shielded within the range of 5 meters, 3 pins of one or more sets of photoelectric switches U2, U3, U4 and U5 can output high levels and respectively enter the positive power input ends of one or more relays K1, K2, K3 and K4, and then one or more relays K1, K2, K3 and K4 can be electrically attracted, and the control contact end and the normally open contact end of the one or more relays are respectively closed. Since the control contact ends and the normally open contact ends of the four relays K1, K2, K3 and K4 are respectively connected with the two contacts below the four wireless signal transmitting keys S1, S2, S3 and S4 of the wireless transmitting circuit module U6, therefore, after the heavy hammer approaches the upper end of the pile foundation within 5 meters, if the heavy hammer approaches the upper end of the pile foundation leftwards, the wireless transmitting circuit module U6 can transmit a first path of wireless closing signal, if approaching the upper end of the pile foundation to the right, the wireless transmitting circuit module U6 will transmit a second wireless closed signal, if the upper end of the pile foundation is approached forwards, the wireless transmitting circuit module U6 can transmit a third wireless closing signal, if the upper end of the pile foundation is approached backwards, the wireless transmitting circuit module U6 can transmit a fourth wireless closing signal, if the upper periphery of the pile foundation is approached at the same time, the wireless transmitting circuit module U6 can transmit a total of four wireless closed signals.

AS shown in fig. 1, 2, 3, 4, and 5, before work, an operator in the weight operating room turns on the power switch AS1 in advance, so that the wireless receiving circuit module U8 is powered on, and in practical cases, when the wireless transmitting circuit module U6 transmits the first path, the second path, the third path, and the fourth path of wireless closing signals according to the vertical offset angle between the weight and the pile foundation, and the wireless receiving circuit module U8 receives the first path, the second path, the third path, and the fourth path of wireless closing signals, its 4 pins, 5 pins, 6 pins, and 7 pins (2 pins are suspended) will output high level, and then the high level is reduced voltage and limited current via the resistors R2, R3, R4, and R5, and then enters the negative power input terminals of the light emitting diodes VL1, VL2, VL3, and VL4, so that the light emitting diodes VL1, VL2, VL3, and VL4 are powered on to emit light. The worker judges the vertical centering condition of the upper end of the pile foundation and the lower end of the heavy hammer according to the light emitting condition of one or more light emitting diodes; for example, the light emitting diode VL1 or VL2 representing that the weight is close to the pile foundation leftwards or rightwards is powered to emit light, and the light emitting diode VL2 or VL1 representing that the weight is close to the pile foundation rightwards or leftwards is not powered to emit light, so that an operator does not need to direct other people to slightly move the weight towards the right end or the left end of the pile foundation until the light emitting diodes VL1 and VL2 are powered to emit light simultaneously, and the weight is close to the upper end of the pile foundation in a left-right position. For example, the light emitting diode VL3 or VL4 representing that the heavy hammer approaches the pile foundation forwards or backwards is powered on to emit light, and the light emitting diode VL4 or VL3 representing that the heavy hammer approaches the pile foundation backwards or forwards is not powered on to emit light, so that an operator does not need to direct other people to slightly displace the heavy hammer towards the rear end or the front end of the pile foundation until the light emitting diodes VL3 and VL4 are powered on to emit light simultaneously, and the heavy hammer approaches the upper end of the pile foundation in front and back positions. When the four light-emitting diodes VL1, VL2, VL3 and VL4 are all powered to emit light, the lower end of the heavy hammer and the upper end of the pile foundation are effectively in a vertical centering state, and the lower end of the heavy hammer and the periphery of the upper end of the pile foundation are vertically overlapped, so that formal hammering operation can be carried out; as the vertical positions of the heavy hammer and the pile foundation are adjusted in place, the pile foundation can be hammered all the time as long as an operator does not move the front, back, left and right positions of the heavy hammer and then the pile foundation can be hammered into the ground to a proper depth. After one pile foundation is hammered, a worker takes down the fixing mechanism from the pile foundation and the like, so that all hammering operations of one pile foundation are completed, the hammering operations are completely consistent with the flow, and the hammering operations of the next pile foundation can be achieved. In the invention, although the hammer can generate vibration, the fixing mechanism is positioned below the upper end of the pile foundation and is not contacted with the hammer, so the vibration can not cause the damage of the equipment.
