Description

The novel electron scale with hook head

Technical field

The utility model relates to a kind of electronic scale with hook head, especially relates to the novel electron scale with hook head that a kind of hoisting crane is used.

Background technology

At present, the electronic crane scale that disclosed hoisting crane is used mainly contains following several structure: first kind of structure, wireless data sending electronic scale with hook head as the exploitation of the open our company of CN2479489Y, be in the scale body of the reverse load of cover mechanism and the pressure type LOAD CELLS on the scale body of packing between pulley assembly and the lifting beam with hook assembly, its advantage weighing precision height, safety is good, can utilize former hook assembly.But because the scale body has increased suspension height, so reduced the lifting height of hoisting crane, the above electronic scale with hook head of general 20t makes the lifting height loss at 320mm～500mm.The electronic scale with hook head of second kind of structure, be that electronic crane scale is directly installed on the crossbeam of suspension hook, though the electronic hanger scale of this kind structure is simple in structure, easy for installation, but owing to can not utilize original suspension hook group, improvement cost is big, and in use there are certain potential safety hazard in high strength shackle and pull-type sensor.In addition, because the lifting height loss of hoisting crane is bigger, the electronic scale with hook head lifting height loss more than the general 20t is at 600mm～1200mm, and field of application is less.The electronic crane scale of the third structure, be that LOAD CELLS is installed on the fixed pulley of hoisting crane, though the electronic crane scale of this structure can not reduce the lifting height of hoisting crane, but because weighting error is big, generally more than 7 ‰, so incompatible as Trade Measures utensil or the occasion strict to Process configuration.

Summary of the invention

Technical problem to be solved in the utility model provides and a kind ofly can guarantee weighing precision, can utilize former lifting beam with hook assembly again, does not lose strode of crane, is convenient to the novel electron scale with hook head of on-the-spot repacking.

The utility model is that the technical scheme that addresses the above problem is: a kind of novel electron scale with hook head, comprise the pulley assembly that constitutes by assembly pulley and main shaft, the lifting beam with hook assembly that constitutes by suspension hook and crossbeam, and scale body and display instrument, it is characterized in that: described scale body comprises the cover of weighing that is fixedly connected on the crossbeam two side ends respectively, be connected two L shaped yoke plates of weighing between pulley assembly and the lifting beam with hook assembly, and the LOAD CELLS that is fixedly connected on the L shaped yoke plate of weighing, LOAD CELLS and crossbeam two side ends weigh the cover with join.

Principle of work of the present utility model is: when the weight of object acts on crossbeam by suspension hook, then the weighing cover of crossbeam both sides is pressed on the sensor, sensor is handled analog voltage signal feed signals processing equipment, analog voltage signal is through amplifying, filter, A/D converts digital signal corresponding to, send into the data processing equipment of display instrument, digitized weight data is carried out computing and processing, obtained actual gravimetric value, show by digital display screen, this weight data can be exported by serial port, can pass through printer prints when needing, send the large screen display demonstration or serve bit machine.

The utility model adopts the advantage of technique scheme to be: the utility model is installed in the scale body on the lifting beam with hook assembly, and only need to install the cover of weighing additional in the crossbeam both sides, weight on the suspension hook is measured by the LOAD CELLS that the cover of weighing reaches on the yoke plate of weighing, its structure is very simple, on the one hand in the lifting operation process, two sensors of crossbeam both sides can keep stress balance, to guarantee weighing precision, on the other hand owing to increase the suspension link, so can not lose the lifting height of hoisting crane, be suitable for the rail yard responsive highly especially to lifting, port and pier, container handling operation, or short factory building metering operation.Secondly, the utility model installs additional on crossbeam weighs cover and constitutes pressure type load mechanism with the L shaped yoke plate of weighing, rational in infrastructure, has eliminated the potential safety hazard in the lifting operation, safe and reliable.Moreover the utility model is owing to all utilize the suspension hook-transverse beam assembly of former usefulness, and the cover that only needs to weigh is installed on the crossbeam and gets final product, and is convenient to on-the-spot repacking, and easy to maintenance.

Description of drawings

Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.

Fig. 1 is a structural representation of the present utility model.

The specific embodiment

Novel electron scale with hook head as shown in Figure 1 comprises the pulley assembly 1 that is made of assembly pulley 1-2 and main shaft 1-1, by the lifting beam with hook assembly 8 that suspension hook 8-2 and crossbeam 8-1 constitute, scale body and display instrument.The scale body comprises 6 and two L shaped yoke plate 2 and the pressure type LOAD CELLS 7 of weighing of cover of weighing that are fixedly connected on crossbeam 8-1 two side ends respectively, see Fig. 1, the cover 6 of weighing is sleeved on the two side ends of crossbeam 8-1, and has notch on the cover 6 of weighing, the notch that two clamps 5 pass the cover 6 of weighing respectively is contained in the draw-in groove 8-1-1 of crossbeam 8-1, and the cover 6 of will weighing fast fixedly is installed on the crossbeam 8-1.The cover 6 of weighing also can directly be connected on the crossbeam 8-1 by fastener, and its type of attachment is not limit.Two L shaped yoke plates 2 of weighing then are connected with the main shaft 1-1 of pulley assembly 1 and the crossbeam 8-1 of lifting beam with hook assembly 8 respectively, on the L shaped yoke plate 2 of weighing pressure type LOAD CELLS 7 is housed, for guaranteeing the mechanical strength of the L shaped yoke plate 2 of weighing, the both sides of the L shaped yoke plate 2 of weighing all are welded with brace panel 9, the cover 6 of weighing joins with pressure type LOAD CELLS 7, and the weight that suspension hook 8-2 is gone up object reaches LOAD CELLS 7 by crossbeam 8-1 and measures.For preventing suspension hook 8-2 when the lifting operation process is rocked or is collided, pressure type LOAD CELLS 7 is deviate from outside cover 6 bottoms of weighing, and is provided with position-limited trough 6-1 in the bottom of the cover 6 of weighing.As adopt the wireless data sending technology, see shown in Figure 1, battery 3 and feedway 4 can on weighing yoke plate 2, the L type be housed, to be processed into digital signal and send to by feedway 4 and deliver to display instrument after digital processing unit is handled, CraneMate, CraneMate II wireless transmission instrument that display instrument can adopt plum Teller-Tuo benefit to produce.The utility model also can adopt the wired digital transmission technology, directly links to each other with display instrument by cable, at this moment, the 8142Pro instrument that display instrument adopts plum Teller-Tuo benefit to produce.
