Abstract
The utility model relates to a composite connection structure of a development machine body and a support body, comprising a machine body connection plate, a screw bolt, a flat key, a screw, a support body connection plate, a hanger and a hanger screw bolt. Lower end flanges of the hanger and the support body connection plate are connected together to form a hanger groove, and the lower end flange of the machine body connection plate is just inserted into the groove; due to interference fit of the hanger groove width and lower flange thickness of the machine body connection plate, the hanger is firmly buckled to the machine body connection plate to form an over-positioning connection, thereby playing double insurance role. The composite connection structure safely transmits the machine body weight and reaction force generated from work to the support body, so as to ensure normal operation of the development machine.
Description
Technical field
The utility model relates to a kind of development machine body and the compound draw bail of supporting mass, belongs to mining machinery.
Background technology
Connect between the development machine vitals is development machine reliability and long-life an important step, particularly development machine body and the connecting of supporting mass (as running part).Because the weight of development machine body is usually between 20 tons to 100 tons, generally support by four groups of this connections, the draw bail of prior art adopts connection of bolt single form or bolt to add the connection of two kinds of forms of flat key more, that is, bolt bears pulling force, flat key bears shearing force.Yet from present mode of occupation, even this kind connects compound connection many failure accidents have appearred also.For the heavy-duty machine type, this kind connection more can not be satisfied the load bearing requirements of large-tonnage mining machinery.
Summary of the invention
The purpose of this utility model is to provide a kind of development machine compound draw bail, makes the connection between vitals more convenient, more reliable.
The utility model is to realize like this, the compound draw bail of a kind of development machine body and supporting mass, comprise body gusset piece, bolt, flat key, screw, supporting mass gusset piece, described flat key is embedded in the keyway between body gusset piece and the supporting mass gusset piece with junction of the edges of two sheets of paper form, with bolted on connection, wherein, described draw bail also comprises hook and hook bolt, the lower end flange of hook and supporting mass gusset piece connects the formation pocket for the punch head with hook bolt, the lower edge of described body gusset piece drops in the above-mentioned pocket for the punch head.The edge thickness fit form is an interference fit under described pocket for the punch head width and the gusset piece.
The utility model has the advantages that: the development machine body connects with supporting mass (as running part), the pipeline of its loading force has three aspects: the firstth, and bolt, bear the pulling force that the horizontal direction left-right and front-back rocks, guarantee the stability of body and running part horizontal direction; The secondth, flat key, bear shearing force, shearing force comprises vertical direction and horizontal direction, and the frictional force under the bolt tension force effect between two sports association's fishplate bars, vertical direction and horizontal direction do not have relative displacement and the reaction force that produces during with complete machine weight and machine works is delivered to the earth between common guarantee body and the running part; The 3rd is hook, bears the shearing force that the pulling force of horizontal direction simultaneously also bears vertical direction, forms a countertorque and finishes its complex function.In fact hook has played the insurance of dual redundancy-type, has improved the reliability of development machine greatly, has prolonged machine application life effectively.
Description of drawings
Accompanying drawing 1 is the compound draw bail assembling drawing of the utility model development machine;
Accompanying drawing 2 is the compound draw bail body of the utility model development machine gusset piece mating face views;
Accompanying drawing 3 is the compound draw bail supporting mass of the utility model development machine gusset piece mating face views.
The specific embodiment
Describe most preferred embodiment of the present utility model in detail below in conjunction with accompanying drawing, the compound draw bail of development machine body and supporting mass is shown in the compound draw bail assembling drawing of Fig. 1 the utility model development machine: comprise body gusset piece 1, bolt 2, flat key 3, screw 4, supporting mass gusset piece 5, hook 6, hook bolt 7.Flat key 3 is embedded in the flat key groove of supporting mass gusset piece 5, shown in the view of the compound draw bail supporting mass of accompanying drawing 3 the utility model development machines gusset piece mating face, and tightens together by screw 4 and supporting mass gusset piece; Flat key groove with body gusset piece 1, shown in the view of the compound draw bail body of Fig. 2 the utility model development machine gusset piece mating face, be buckled on the flat key, and connect with supporting mass gusset piece 5 with bolt 2, the lower edge of body gusset piece 1 is tight against the lower end flange of supporting mass gusset piece 5; The lower end flange of hook 6 by hook bolt 7 and supporting mass gusset piece 5 tighten together and form a pocket for the punch head, and the lower edge of body gusset piece 1 just in time is inserted in the groove; Because edge thickness fitting-type formula is an interference fit under pocket for the punch head width and the body gusset piece, feasible hook is waled the body gusset piece tightly, form one and cross the location connection, play the double insurance effect, the powerful reaction force of weight that body is huge and work generation passes on the supporting mass by above-mentioned duplex and then imports the earth into like this.The compound connection of the utility model has shown tangible reliability aborning.
Claims (2)
1. the compound draw bail of development machine body and supporting mass, comprise body gusset piece (1), bolt (2), flat key (3), screw (4), supporting mass gusset piece (5), described flat key (3) is embedded in the keyway between body gusset piece (1) and the supporting mass gusset piece (5) with junction of the edges of two sheets of paper form, with bolted on connection, it is characterized in that: described draw bail also comprises hook (6) and hook bolt (7), the lower end flange of hook (6) and supporting mass gusset piece (5) connects the formation pocket for the punch head with hook bolt (7), and the lower edge of described body gusset piece (3) drops in the above-mentioned pocket for the punch head.
2. according to the compound draw bail of described development machine body of claim (1) and supporting mass, it is characterized in that: the edge thickness fit form is an interference fit under described pocket for the punch head width and the gusset piece.
