Abstract
The utility model relates to a trolley frame type weighing device belonging to the technical field of garbage treatment device. The utility model comprises a trolley frame, which is constituted by an upper layer and a lower layer trolley frame, thereby the upper layer trolley frame is connected to the lower layer trolley frame through a sensor, a horizontal and a vertical supporting rod. By using the double layer of trolley frames provided in the utility model, the precision and stability of weighing can be improved, because all pressures caused by the upper layer trolley frame and all parts of the upper layer trolley frame are vertically applied on the sensor.
Description
Technical field
The utility model relates to the refuse disposal system technical field, is specifically related to a kind of dolly posture meausring apparatus of waste handling grab car posture.
Background technology
The waste handling bridge grabbing crane is that the nucleus equipment major part of garbage incinerating power plant has crane span structure, dolly, traveling mechanism of the larger traveller and garbage grab bucket, and garbage grab bucket is a part and the load-engaging device of the lifting mechanism of hoisting crane.Crane operation worker manipulating crane finish rubbish carrying, stir, feed intake, task such as collapse of setting, weighing.
The dolly of traditional hoisting crane adopts two reductors of a direct motor drive and two cable drums, and cable drum is connected with grab bucket by steel rope.The lasting rotating of motor can realize grabbing bucket hoists and descends.Under the bearing base of each reel one end weighing sensor is installed, sensor and reel base are rigidly connected, the weight of material in the collection by the weighing signal and the conversion weighing garbage grab bucket of analog quantity and digital quantity.
Traditional weighing version is simple, install easily manufactured, but owing to only be rigidly connected between sensor installation and sensor and the base under the base of reel one end, so be difficult to eliminate since the side force of garbage grab bucket generation to the influence of weighing precision.This weighing structure causes weighing precision and stability not high, is difficult to satisfy the requirement of client to weighing.
The utility model content
The technical problems to be solved in the utility model provides a kind of weighing precision and all good dolly posture meausring apparatus of stability.
In order to achieve the above object, the technical solution adopted in the utility model is: a kind of dolly posture meausring apparatus, comprise trolley frame, and described trolley frame comprises upper trolley frame and lower floor's trolley frame;
In the such scheme, described upper trolley frame connects lower floor's trolley frame by sensor, transverse support bar, vertical strut bar;
In the such scheme, described sensor is a weighing sensor;
In the such scheme, described weighing sensor is connected with described levels trolley frame respectively by bolt, nut, packing ring;
In the such scheme, described weighing sensor comprises fulcrum ball;
In the such scheme, described fulcrum ball is in the middle of the described weighing sensor;
In the such scheme, described fulcrum ball has activity space in weighing sensor;
In the such scheme, described transverse support bar is connected with described levels trolley frame respectively by nut, packing ring;
In the such scheme, between described transverse support bar and the described levels trolley frame adjusting play is arranged;
In the such scheme, described vertical strut bar is connected with described levels trolley frame respectively by nut, packing ring;
In the such scheme, be provided with the adjusting play between described vertical strut bar and the described levels trolley frame.
Compared with prior art, the beneficial effect of technical solutions of the utility model generation is as follows:
The utility model has adopted the double-layer trolley rack and panel construction, and upper trolley frame and be positioned at the pressure that the deadweight of all parts on the upper trolley frame produces and all vertically act on sensor has improved the precision and the stability of weighing.
Description of drawings
The structural representation of the dolly posture meausring apparatus that Fig. 1 provides for the utility model embodiment;
Reference numeral:
1-lower floor trolley frame, 2-upper trolley frame, the 3-weighing sensor, the 4-transverse support bar,
The vertical strut bar of 5-, 6-upper support frame, 7-lower support frame, 8-fulcrum ball.
The specific embodiment
Below in conjunction with drawings and Examples the technical solution of the utility model is described in detail.
Referring to Fig. 1, the utility model embodiment provides a kind of dolly posture meausring apparatus, comprise lower floor's trolley frame 1, upper trolley frame 2, weighing sensor 3, transverse support bar 4, vertical bracing frame 5, upper support frame 6, lower support frame 7, wherein, parts such as the lifting motor of hoisting crane, the reductor that hoists, reel, drg all are positioned on the upper trolley frame 2, and trolley travelling actuating device and four set of wheels are positioned on lower floor's trolley frame 1; Upper trolley frame 2 is connected with lower floor trolley frame 1 by four weighing sensors 3 and transverse support bar 4 and vertical strut bar 7, and described weighing sensor passes through bolt, nut, packing ring and is connected with upper trolley frame 2 with lower floor trolley frame 1.
By weighing structure design of the present utility model, make upper trolley frame 2 and be positioned at the pressure that the deadweight of all parts on the upper trolley frame 2 produces and all vertically act on the weighing sensor 3, the structure of weighing sensor 3 is special pressure type sensor, each weighing sensor 3 is divided into two up and down, the centre is one can oligodynamic fulcrum ball 8, and this fulcrum ball can be high strength Metal Ball such as steel ball.
Simultaneously, transverse support bar 4 is connected the levels trolley frame with vertical strut bar 5 by nut, packing ring, but nut, packing ring and upper trolley frame 2 and lower floor's trolley frame 3 on the vertical strut bar leave the adjusting play; Transverse support bar and upper support frame 6, lower support frame 7 also leave the adjusting play; so transverse support bar 4 and vertical strut bar 5 only shield in normal operation; do not bear external force such as vertical load and horizontal load; so the utility model has guaranteed upper trolley frame 2 and be positioned at the pressure that the deadweight of all parts on the upper trolley frame 2 produces all vertically to act on the weighing sensor 3, this kind structure has improved the precision and the stability of weighing greatly.
The above only is preferred embodiment of the present utility model, and not in order to restriction the utility model, common variation that those skilled in the art carries out in the technical solutions of the utility model scope and replacement all should be included in the protection domain of the present utility model.
