Description

Technical Field

[0001] The utility model relates to the technical field of lifting equipment, in particular to a hanging bracket with a balance prompt function. Background Technique

[0002] When a crane or other lifting mechanism hoists a large and irregularly shaped equipment, etc., a hanging bracket is used to cooperate with the lifting mechanism for operation. Specifically, during the operation, the rings connected to the upper parts of multiple steel wires installed around the hanging bracket are hung together with the hook of the lifting mechanism. In addition, the lower ends of multiple steel wires are sleeved on the left and right parts of the lower side end of the equipment, etc. (both ends of each steel wire are installed at the corresponding front and rear positions of the lower part of the hanging bracket, and the steel wire can be sleeved on the hoisting operation point of the equipment. Different steel wires adapt to different lengths of the hoisting surface of the equipment), so as to provide as many hoisting points for the equipment as possible, so that the equipment can be kept as balanced as possible during hoisting, reducing the problems of equipment tilt during hoisting and affecting hoisting safety.

[0003] Although the existing hanging bracket cooperating with the lifting mechanism and other operations can meet the hoisting use of the equipment to a certain extent, due to structural limitations, there are still some technical problems. Specifically, affected by the incorrect operation methods of the ground staff (one or more corresponding steel wires are not effectively sleeved on the corresponding hoisting positions of the equipment), and after a long use time and the steel wire length becomes longer, there is a probability that the hoisted equipment tilts forward and backward or left and right after leaving the ground. When the ground staff does not timely discover the situation and prompt the driver operating the lifting mechanism, and since the driver operating the lifting mechanism cannot discover the situation and handle it in the first time, in this way, there is a probability that the hoisted equipment slips off the steel wire after reaching a high height from the ground, and then the equipment, etc. is damaged (in extreme cases, the dropped equipment will also cause personal injuries to the ground staff). Content of the Utility Model

[0004] In order to overcome the disadvantages of the existing hanging bracket due to structural limitations as described in the background, the utility model provides a hanging bracket with a balance prompt function based on the hanging bracket body. Under the joint action of relevant mechanisms, it can real-time monitor the balance degree around the hanging bracket body. When the hanging bracket body tilts to one side due to various reasons during hoisting, it can timely prompt the driver in the cab of the lifting mechanism in a wireless manner to pay attention to safe operation, reducing the probability of equipment damage caused by the separation of the equipment and the hanging bracket body and the injury of ground operation personnel, etc.

[0005] The technical solution adopted by the utility model to solve its technical problems is:

[0006] The hanging bracket with a balance prompt function includes a hanging bracket body, and is characterized in that it also has a detection mechanism and a receiving mechanism; there are multiple sets of the detection mechanisms, and each set of the detection mechanisms includes an outer shell, a pressure sensor, a suspension rod, a wireless detection and transmission circuit, and a storage battery. On one side inside the outer shell, a fixed seat is fixedly installed, the pressure sensor is fixedly installed on one side of the fixed seat, the upper end of the suspension rod is rotatably installed at the upper end inside the outer shell, a counterweight ball is fixedly installed at the lower end of the suspension rod, and one side of the suspension rod and the force-receiving surface of the pressure sensor are in a vertical plane; a magnet is fixedly installed at the outer rear end of the outer shell, the wireless detection and transmission circuit and the storage battery are fixedly installed inside the outer shell, and the outer shells of multiple sets of the detection mechanisms are respectively attracted to the outer side ends around the hanging bracket body by the magnets; the two poles of the storage battery are electrically connected to the power input ends of the pressure sensor and the wireless detection and transmission circuit, and the signal output end of the pressure sensor is electrically connected to the power input end of the wireless detection and transmission circuit; the receiving mechanism is installed in the cab of the hoisting mechanism, and the receiving mechanism includes a wireless receiving circuit and a power supply module.

[0007] Further, among the multiple sets of the detection mechanisms, the pressure sensors and the suspension rods of the detection mechanisms at the left and right side ends are horizontally in a straight line structure, and the pressure sensors and the suspension rods of the detection mechanisms at the front and rear side ends are vertically in a straight line structure.

[0008] Further, when the outer shell of each set of the detection mechanisms is horizontal, one side end of the suspension rod and the force-receiving surface of the pressure sensor are in a separated state.

[0009] Further, the wireless detection and transmission circuit includes an adjustable resistor, a resistor, a relay, a wireless transmission circuit module, and a driving switch integrated circuit that are electrically connected. One end of the adjustable resistor, one end of the resistor, and the signal input end of the driving switch integrated circuit are connected. The positive power input end of the driving switch integrated circuit and the relay control power input end are connected. The output end of the driving switch integrated circuit and the positive power input end of the relay are connected. The negative power input end of the driving switch integrated circuit and the negative power input ends of the relay, the other end of the resistor, and the negative power input end of the wireless transmission circuit module are connected. The positive power input end of the wireless transmission circuit module and the normally open contact end of the relay are connected, and the two contacts under one of the buttons of the wireless transmission circuit module are connected together.

[0010] Further, the wireless receiving circuit includes a wireless receiving circuit module and an alarm that are electrically connected. The power input end of the four-way alarm and the four-way power output ends of the wireless receiving circuit module are respectively connected.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows: Based on the hanger body, under the combined action of relevant mechanisms, the four sets of detection mechanisms can monitor the balance degree around the hanger body in real time. When the hanger body tilts to one side due to various reasons during hoisting, the suspension rod of a corresponding set of detection mechanisms can exert a force on the pressure surface of a corresponding set of pressure sensors, and a corresponding set of wireless transmission circuit modules will transmit a corresponding wireless closing signal. After the wireless receiving circuit module in the cab receives the corresponding wireless closing signal, it can make a corresponding alarm be powered on and work, and give an audible and visual warning to the staff in the cab about which side the hanger body tilts too much. In this way, the driver in the cab can pay attention to safe operation, reducing the probability of equipment damage caused by the separation of the equipment and the hanger body and the injury of ground operators, etc. In summary, the present utility model has good application prospects.

A fixing seat 1011 is installed at one side end inside the outer housing 101. The pressure sensor T1 is installed on one side of the fixing seat 1011 through bolts. The upper end of the suspension rod 102 is rotatably installed at the upper end inside the outer housing 101. A metal ball 1012 (which plays the role of counterweight and stabilizing the suspension rod 102) is welded to the lower end of the suspension rod 102. The middle part of one side of the suspension rod 102 and the force-receiving surface of the pressure sensor T2 are perpendicular and in a straight line. A rectangular permanent magnet 103 is adhesively bonded to the outer side end at the rear of the outer housing. The wireless detection and transmission circuit 104, the storage battery G1, the power socket CZ1, and the power switch S1 are installed on the circuit board inside the outer housing 101, and the handle of the power switch S1 and the jack of the power socket CZ1 are respectively located outside the front opening of the outer housing 101. The receiving mechanism is installed in the cab of the hoisting mechanism, and the receiving mechanism includes a wireless receiving circuit 22 and a power module T4 which are installed in the component box 21 and connected by wires.

[0017] Figure 1 , 2As shown in Figures 1, 2, and 3, the outer shells of the four sets of detection mechanisms are respectively installed in the middle of the left and right and front and rear sides of the hanger body 1 by magnetic attraction of the magnet 103 (magnetic attraction facilitates the removal of the detection mechanism for charging the internal battery). Among them, the pressure sensors T1 of the lifting mechanisms at the left and right sides and the suspension rods 102 are horizontally in a straight line structure from left to right, and the suspension rods 102 can move left or right along the upper mounting points. The pressure sensors T1 of the lifting mechanisms at the front and rear sides and the suspension rods 102 are vertically in a straight line structure from front to back, and the suspension rods 102 can move forward or backward along the upper mounting points. When the outer shell 101 of each set of detection mechanisms is horizontal, one side end of the suspension rod 102 and the force-receiving surface of the pressure sensor T1 are in a separated state. The wireless detection and transmission circuit of each set of detection mechanisms includes a variable resistor RP1, a resistor R1, a relay J1, and a wireless transmission circuit module T3, and a drive switch integrated circuit T2 connected by circuit board wiring. One end of the variable resistor RP1, one end of the resistor R1, and the signal input terminal 5 of the drive switch integrated circuit T2 are connected. The positive power input terminal 1 of the drive switch integrated circuit T2 and the control power input terminal of the relay J1 are connected. The output terminals 2 and 3 of the drive switch integrated circuit T2 and the positive power input terminal of the relay J1 are connected. The negative power input terminal 4 of the drive switch integrated circuit is connected to the negative power input terminal of the relay J1, the other end of the resistor R1, and the negative power input terminal of the wireless transmission circuit module T3. The positive power input terminal of the wireless transmission circuit module T3 is connected to the normally open contact terminal of the relay J1. Among the wireless transmission circuit modules T3 of the four sets of detection mechanisms, the two contacts under the first button D1 of the first wireless transmission circuit module T3 are connected together, the two contacts under the second button D2 of the second wireless transmission circuit module T3 are connected together, the two contacts under the third button D3 of the third wireless transmission circuit module T3 are connected together, and the two contacts under the fourth button D4 of the fourth wireless transmission circuit module T3 are connected together. The wireless receiving circuit includes a wireless receiving circuit module T5 and alarms H1, H2, H3, and H4 connected by circuit board wiring. The power input terminals of the four-way alarms H1, H2, H3, and H4 and the four-way power output terminals 3, 4, 5, 6, and 2 of the wireless receiving circuit module T5 are respectively connected.

[0018] Figure 3As shown, in each set of detection mechanisms, both poles of the storage battery G1 and both ends of the charging socket CZ1 are respectively connected by wires (when the storage battery G1 has no power, the plug of an external 12V power charger can be inserted into the jack of the charging socket CZ1 to charge it, and the jack of the charging socket CZ1 is located at the front outer side end of the outer casing), and are connected in series through the power switch S1 and the power input terminals 1 and 2 of the pressure sensor T1, and the power input terminal of the relay J1 that controls the power input of the wireless detection and transmission circuit and the negative power input terminal of the relay J1 are respectively connected by wires. The signal output terminal 3 of the pressure sensor T1 and the other end of the adjustable resistor RP1 at the signal input end of the wireless detection and transmission circuit are connected by wires. The power output terminals 3 and 4 of the power module T4 and the power input terminals 1 and 2 of the wireless receiving circuit module T5 are respectively connected by wires, and the power input terminals 1 and 2 of the power module T4 and the AC 220V power supply are connected by wires. Figure 3 , 4 In, the power module T4 is a finished product of an AC 220V to DC 12V switching power supply module; the power switch S1 is a toggle power switch (the handle is located outside the opening at the front end of the electric control box); the model of the relay J1 is DC12V; the wireless transmission circuit module T3 and the wireless receiving circuit module T5 are finished products of a four-way wireless transmission and wireless receiving module component of model APAC-4S. The wireless transmission module has four wireless signal transmission buttons, and the wireless receiving module has four output terminals (the working principle is the same as that of the existing vehicle-mounted wireless transmission and wireless receiving module component); the driving switch integrated circuit T2 is a finished product of a high-power driving switch integrated circuit of model TWH8778, which has two power input terminals 1 and 2, a signal input terminal 5, and two power output terminals 2 and III (connected in parallel). When the voltage signal input at the signal input terminal is higher than 1.6V, the power output terminal outputs power; the alarm devices H1, H2, H3, and H4 are finished products of small-sized strobe warning light and sound alarm devices of model LTE-5061, and their light-emitting surfaces are respectively located outside the four openings at the front end of the component box; the pressure sensor T1 is a finished product of a high-precision micro pressure sensor of model DYZ-100. When different pressures act on the force-receiving surface during operation, its signal output terminal will output a voltage signal that varies between 0 and 10V; the resistance value of the adjustable resistor RP1 is 100K (the larger the resistance value, the greater the voltage division between it and the resistor R1. In this way, when the pressure on the force-receiving surface of the pressure sensor T1 is greater, the signal voltage entering the 5th pin of the driving switch integrated circuit will exceed 1.6V; the smaller the resistance value, the smaller the voltage division between it and the resistor R1. In this way, when the pressure on the force-receiving surface of the pressure sensor T1 is smaller, the signal voltage entering the 5th pin of the driving switch integrated circuit will exceed 1.6V); the resistance value of the resistor R1 is 10K; the storage battery G1 is a lithium storage battery of model 12V / 10Ah. Figure 3 , 4 In, all the electronic components are existing mature products, and the working principle thereof will not be elaborated in this application.

[0019] Figure 1 and 2 As shown in Figures 3 and 4, in the application of the hanger body 3, when a crane or other hoisting mechanism hoists a large and irregularly shaped device, etc., the rings 31 connected to the upper parts of multiple steel wires installed around the hanger body 3 are hooked together with the hook of the hoisting mechanism. In addition, the lower ends of multiple steel wires (not shown in the figure) are sleeved on the left and right parts of the lower side end of the device, etc. (both ends of each steel wire are installed at the corresponding front and rear positions at the lower part of the hanger body 3, and the steel wire can be sleeved on the hoisting operation points of the device. Different steel wires adapt to different hoisting surfaces and different lengths of the device), so as to provide as many hoisting points for the device as possible. After the power module T4 is powered on, its pins 3 and 4 output a stable DC 12V power supply and enter the power input terminal of the wireless receiving circuit. After turning on the power switch S1 of the four sets of detection mechanisms, the pressure sensors of the four sets of detection mechanisms and the power input terminals of the wireless detection and transmitting circuits are powered on. When the hanger body 3 hoists the device and leaves the ground without tilting to the left or right or to the front or rear side, the suspension rod 102 of a corresponding set of detection mechanisms does not contact the force-receiving surface of a corresponding set of pressure sensors T1, or the tilting angle is small (such as less than 2°), the contact force between the suspension rod 102 and the force-receiving surface of a corresponding set of pressure sensors T1 is small, and the pressure acting on the force-receiving surface of the pressure sensor T1 is relatively smaller. The voltage signal output by the pressure sensor T1 is divided by the adjustable resistor RP1 and the resistor R1 and enters the 5th pin of the driving switch integrated circuit T2, and the signal is lower than 1.6V. The 2nd and 3rd pins of the driving switch integrated circuit T2 do not output power, and the wireless transmitting circuit module will not transmit a corresponding wireless closing signal. When the hanger body 3 hoists the device and tilts to the left or right or to the front or rear side by an angle greater than a certain value (such as greater than 2°), the contact force between the suspension rod 102 of a corresponding set of detection mechanisms and the force-receiving surface of a corresponding set of pressure sensors T1 is relatively large, and the pressure acting on the force-receiving surface of the pressure sensor T1 is relatively larger. The voltage signal output by the pressure sensor T1 is divided by the adjustable resistor RP1 and the resistor R1 and enters the 5th pin of the driving switch integrated circuit T2, and the signal is higher than 1.6V. The 2nd and 3rd pins of the driving switch integrated circuit T2 output power. Furthermore, the relay J1 is powered on and its control power input terminal and normally open contact terminal are closed. When a corresponding set of detection mechanism relay J1 is powered on and closed, since the two contacts under the first button D1 of the wireless transmitting circuit module T3 of the first set of detection mechanisms are connected together, the two contacts under the second button D2 of the wireless transmitting circuit module T3 of the second set of detection mechanisms are connected together, the two contacts under the third button D3 of the wireless transmitting circuit module T3 of the third set of detection mechanisms are connected together, and the two contacts under the fourth button D4 of the wireless transmitting circuit module T3 of the fourth set of detection mechanisms are connected together, when a corresponding set of detection mechanisms tilts, the wireless transmitting circuit module T3 of the corresponding set of detection mechanisms will be powered on and transmit the first or second, third, and fourth wireless closing signals.

[0020] Figure 1 , 2 As shown in Figures 3 and 4, when the wireless transmission circuit module T3 of a corresponding set of detection mechanisms is powered on and emits the first, second, third, or fourth wireless closing signal, after the wireless reception circuit module T5 receives it, its pins 3 or 4, 5, and 6 will output a high level and enter the power input terminals of the warning lights H1 or H2, H3, H4. In this way, the warning lights H1 or H2, H3, H4 will be powered on and work, and a corresponding warning light will emit an audible and visual alarm signal to prompt the staff in the cab which side of the hanger body has an excessive inclination angle. In this way, the driver in the cab can pay attention to safe operation (the hoisted equipment can be lowered to allow the ground operators to re-fix the position between the steel wire rope and the equipment), reducing the probability of equipment damage caused by the separation of the equipment and the hanger body and the injury of ground operators and others.
