Description
Technical field
The utility model relates to a kind of weight sensor, specifically is a kind of single-sheaved block formula weight sensor that is applied to the tower machine.
Background technology
The tower machine is a most widely used conveying arrangement on the building ground, is bearing to grow on the building site and is transporting apart from the high-altitude.But because its lifting altitude height, to play liter weight big, danger coefficient is very big in use, will cause wire cable rupture in case play the ability to bear that liter weight surpasses steel rope, and weight falls to injuring by a crashing object people or the thing under the tower machine.All be provided with weight sensor and monitored control system on the existing tower machine, be used for measuring at any time, showing hoisting capacity.The weight sensor that is applied to the tower machine at present mostly is non-axle type structure greatly, this sensor is installed inconvenient, also having a kind of is at pulley center axle place suit axle type sensor, pulley is fixed on tower crown end, walk around pulley by steel rope the pressure of sheave shaft is recorded hoisting capacity, this sensor installation site is fixed, and can not regulate stressed size, so the hoisting capacity scope is little.Though other has a kind of three pulley force transducers to overcome original weight sensor installation site mono-shortcoming, must use three pulleys simultaneously, waste material.
Summary of the invention
At the problems referred to above, the utility model provides a kind of single-sheaved block formula weight sensor with multiple mounting means, stressed adjustable size joint.
Single-sheaved block formula weight sensor described in the utility model, comprise baffle plate, pulley, connecting panel, weight shaft, pressure frame plate, side plate, the wheel shaft of its middle pulley is fixed on the baffle plate of both sides, baffle plate connects with side plate by connecting panel, described baffle edge is provided with retaining rope pin, be provided with weight shaft in the middle of the biside plate and press frame plate, press frame plate one end to connect with connecting panel, the other end connects with weight shaft.Be connected with output cable on the described weight shaft.Raising line is walked around pulley, and during to the pulley application of force, pulley drives by the connecting panel that connects with it and presses frame plate, and by pressing frame plate that weight shaft is exerted pressure or pulling force, weight shaft is transferred to ECU (Electrical Control Unit) with the signal that records by output cable.
In the said apparatus, the described side plate outside is fixed with antiturning fastener board, and the antiturning fastener board edge contacts with weight shaft.Described antiturning fastener board is a rectangular metal plate, is fixed on the side plate with screw.This device can prevent to rotate when weight shaft is stressed, influences result of a measurement.The installation site of antiturning fastener board determines according to the force direction that is subjected to of weight shaft, should guarantee that weight shaft do not rotate, and can't influence its stressed size.When raising line was walked around pulley from the right side, weight shaft was pointed to the pressure effect of lower left, and the antiturning fastener board correspondence is located at the weight shaft upper left side; When raising line was walked around pulley from the left side, weight shaft was pointed to top-right tension, and the antiturning fastener board correspondence is located at the weight shaft lower right.
In the said apparatus, the quantity of retaining rope pin is at least 3 on the described baffle plate.Can retaining rope pin also can be set separately with the connector of fixing two baffle plates as retaining rope pin, the utility model is to fix the bolt of two baffle plates as retaining rope pin.By the quantity and the position of retaining rope pin are set, play the size of regulating the cornerite of raising line on pulley, and then regulate stressed size.
In the said apparatus, described side plate is provided with mounting hole, is used for this device is fixed on the tower machine.
The utility model is installed in weight shaft on the side plate, by pressing frame plate to the weight shaft application of force, and utilizes retaining rope pin to regulate raising line cornerite size, thereby regulates the stressed size of weight shaft, has enlarged the lifting scope of tower machine.The utility model only uses a pulley, and simple in structure, mounting means is flexible, saves cost, and measurement range is wide, is highly suitable for the vehicle for construction field and promotes.

The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described in detail:
Embodiment of the present utility model comprises baffle plate 1, pulley 3, connecting panel 4, weight shaft 9, presses frame plate 11, side plate 5, the wheel shaft of its middle pulley 3 is fixed on the baffle plate 1 of both sides, two baffle plates 1 are fixedly connected by 5 bolts 2, wherein 1 bolt is positioned in the middle of baffle plate 1 right hand edge, and all the other 4 lay respectively at baffle plate about in the of 1 both sides; Each fixes a connecting panel 4 two baffle plate 1 outsides, connecting panel 4 one ends connect with the wheel shaft of pulley 3, the other end connects with side plate 5, two blocks of side plates 5 are fixedly connected by 2 bolts 6, be provided with weight shaft 9 in the middle of the biside plate 5 and press frame plate 11, weight shaft 9 two ends are fixed on the side plate 5, press frame plate 11 two ends to connect with connecting panel 4 and weight shaft 9 respectively, are connected with output cable 10 on the weight shaft 9.Weight shaft 9 one sides are provided with antiturning fastener board 8, and side plate 5 is provided with mounting hole 7.
During installation, as shown in Figure 5, welding one erecting frame 13 on tower cap or tower arm is fixed on this device on the erecting frame 13 in advance, and the fixed position will make the pulley of weight sensor just in time paste mutually with raising line.As shown in Figure 3, raising line 12 can be passed in the slit between pulley 3 right sides and the bolt 2 during installation, at this moment antiturning fastener board 8 should be arranged on the upper left side of weight shaft 9, guarantees raising line 12 and between the bolt 2 certain distance is arranged up and down, prevents to rub between the two; As shown in Figure 4, also raising line 12 can be walked around from pulley 3 left sides during installation, at this moment antiturning fastener board 8 should be arranged on the lower right of weight shaft 9.Different rope-winding methods can be realized the adjusting to cornerite.
