Description
Technical field
The utility model relates to a kind of weighting apparatus, particularly a kind of weighting apparatus that is installed on the diesel fork lift truck.
Background technology
In logistics operations such as railway, highway, commerce and trade, industrial and mineral, fork truck is a kind of important handbarrow, and in order to increase productivity, people are installed a kind of weighing sensing device additional on fork truck, can realize that the carrying of goods and weighing carry out synchronously.And the weighing sensing device on the present fork truck only adapts on the plate that is installed in fork truck or is installed between the guide pillar and fork of fork truck, they are the structure more complicated of itself not only, and be not easy to install and maintenance, have for the local structure that weighing sensing device must change fork truck is installed.In addition, the weighing sensing device on the existing fork truck does not have off-load and overload protection device, and sensor is easy to damage.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, and it is all very convenient to propose a kind of simple structure, installation and maintenance, and has the fork truck weighting apparatus of off-load and overload protection function.
The solution that realizes above-mentioned purpose is: a kind of fork truck weighting apparatus with off-load and overload protection, it mainly pulls to LOAD CELLS, unloading protection equipment and overload protection device by header board, back plate, two and the weight display instrument is formed.Described header board and back plate couple together by the flexible beam that is fixed on the end face of both sides, and make header board parallel with two plate faces of back plate, leave the gap that LOAD CELLS is installed between face and the face, described two tops that pull to LOAD CELLS are connecting oscillating bearing, and be fixedly mounted on the top of the positive both sides of plate, back respectively by bearing rod, the bottom of two sensors is fixedly mounted on the below of both sides, the header board back side respectively by force-transmitting block, and LOAD CELLS is connected with described weight display instrument by lead; Described unloading protection equipment is fixedly mounted on the top of described oscillating bearing; Described overload protection device is fixedly mounted on the below of described force-transmitting block; The two ends, the left and right sides of plate upper edge, described back respectively have one to go up hook, and the upper edge of fork hanging frame is complementary on this hook and the fork truck.This device is articulated on the fork hanging frame of fork truck by the hook of plate upper edge, back, the fork of fork truck is articulated on the header board to get final product again.During work, the cargo weight that carries on the fork acts on the sensor by header board, and sensor exports electric signal to the weight display instrument, thereby reaches the purpose of weighing.
Above-mentioned unloading protection equipment is made of two rigid elements up and down; a front that is fixedly mounted on the back plate; as upper; another is fixedly mounted on the back side of header board; as the next, both misplace up and down, and definite spacing is arranged; land moment at the fork truck fork and can prevent effectively that the header board return is excessive, make sensor avoid vertical extruding.
Above-mentioned overload protection device is made of two rigid elements up and down, and a back side that is fixedly mounted on header board is as upper; another is fixedly mounted on the front of back plate, and as the next, both misplace up and down; and definite spacing arranged; behind the fork truck bearing goods, header board moves down, if overload; upper will be subjected to the next to stop; make header board no longer descending, so just prevented the excessive tensile deformation of elastic body of sensor, played overload protective function.
During fork truck work, unbalance stress often on the left and right sides prong of fork, in order to prevent the occurred level displacement on hanging frame of this device, medium position in plate upper edge, described back is provided with a horizontal limiting stopper, this limiting stopper is connected on the original breach of fork truck hanging frame, unbalance stress how on the prong of the left and right sides no matter, this device can the occurred level slippage yet.
In addition, at the two ends, lower edge of described back plate a lower draw-bar is set respectively.When after after plate is articulated on the hanging frame, tangle the lower edge of hanging frame again by described lower draw-bar, so just can guarantee the more firm connection on hanging frame of this device,, also can prevent the weighting apparatus upset even unexpected off-load of fork or stressed pulling forward take place.
Also have,, an observation window respectively is set at the medium position of described header board and back plate for the mode of operation of direct viewing fork truck.
The utility model weighting apparatus has off-load and overload protection facility, inherently safe coefficient height, long service life.Integral body combines with the fork truck front end to articulate form, so its Assembly ﹠Disassembly is all very convenient.
