Abstract
The utility model relates to a connecting structure of mining equipment, in particular to a cross-connecting structure solving the problems of poor geological condition suitability, assembly, maintenance and replacement process, low safety and reliability, and the like existing in the prior art. The connecting structure comprises a connecting shaft and a connecting seat in rigid connection or articulation, a limit surface is arranged on the connecting seat, the connecting shaft of the cross-connecting structure is connected with a connected structure (A) together through a locking plate, and a connecting seat of the cross-connecting structure is connected with a connected structure (B) together through a pin shaft so that the structure (A) has the functions of swinging up and down and left and right relative to the structure (B). The cross-connecting structure of the utility model can be used for connecting a walking hydraulic support top beam and a masking beam for mining, not only can greatly improve the pressure condition of the hydraulic support, but also can evenly prop the top beam to favorably suit the corrugation of a top plate and a bottom plate of a working surface.
Description
Technical field
The utility model relates to the draw bail of mining equipment, is specially a kind of cross syndeton.
Background technology
Mining equipment needs mechanical connecting structure to have characteristics such as the bearing load ability is big, connection is reliable, compliance is strong because of requirements such as geological conditions, working condition and service conditions.At present, for the syndeton of mining equipment travelling hydraulic support back timber and caving shield, the manufacturability of geology adaptability for working condition, assembling, maintenance and replacing is not fine, and safety and reliability are not high.Therefore, await developing a kind of novel cross syndeton and solve the problems referred to above.
The utility model content
The purpose of this utility model is to provide a kind of cross syndeton, the manufacturability that solves the geology adaptability for working condition, assembling, maintenance and the replacing that exist in the prior art is bad, problems such as safety and reliability are not high, connected structure first can be remained valid under big external load with structure second to be connected, and make connected structure first have the function that swings up and down and swing, satisfy the specific (special) requirements of using with respect to structure second.
The technical solution of the utility model is:
A kind of cross syndeton is made up of connecting axle and Connection Block, can adopt between connecting axle and the Connection Block to be rigidly connected, and also can adopt hinged.
Described cross syndeton, the connecting axle of cross syndeton links together by jam plate and connected structure first, the Connection Block of cross syndeton links together by bearing pin and connected structure second, can make the structure first have the function that swings up and down and swing with respect to structure second.
Described cross syndeton, the Connection Block of cross syndeton is provided with confined planes.
Described cross syndeton has pin-and-hole on the Connection Block of cross syndeton.
The beneficial effects of the utility model are:
1, cross syndeton of the present utility model makes connected structure first can remain valid under big external load with structure second and is connected.
2, cross syndeton of the present utility model makes connected structure first have the function that swings up and down and swing with respect to structure second, satisfies the specific (special) requirements of using.
3, cross syndeton of the present utility model, when connected structure first is swung with respect to structure second, can be spacing when reaching capacity the position, safe and reliable.
4, cross syndeton of the present utility model can be used for the colliery with being connected of travelling hydraulic support back timber and caving shield, and the hydraulic support stressing conditions is greatly improved, and can also make back timber evenly connect the top, adapts to the fluctuating of work plane roof and floor preferably.
5, the utility model is not limited to and is used in travelling hydraulic support, under the prerequisite that does not break away from the utility model principle, also can be used for the draw bail of other mining equipments.
Description of drawings
Fig. 1 is a cross syndeton schematic diagram of the present utility model.
Fig. 2 is the left view of cross syndeton of the present utility model on the crawler travel support.
Fig. 3 is the front view of cross syndeton of the present utility model on the crawler travel support.
Among the figure: 1, Connection Block; 2, connecting axle; 3, back timber; 4, caving shield; 5 jam plates; 6, stop pad and bolt; 7, bearing pin; 8 baffle plates; 9, lock pin and D shape card; 10, cross syndeton; 11 confined planes; 12 pin-and-holes.
The specific embodiment
Below in conjunction with accompanying drawing the utility model being described further, is the application of cross syndeton on the crawler travel support in the present embodiment.
As shown in Figure 1, cross syndeton concrete structure of the present utility model is as follows: cross syndeton 10 is made up of Connection Block 1 and connecting axle 2, can adopt between connecting axle 2 and the Connection Block 1 to be rigidly connected, and also can adopt hinged.The Connection Block 1 of cross syndeton 10 is provided with confined planes 11, has pin-and-hole 12 on the Connection Block 1.
As shown in Figures 2 and 3, cross syndeton 10 is installed between back timber 3 and the caving shield 4.The connecting axle 2 of cross syndeton 10 1 ends inserts in the boss of back timber 3, with jam plate 5 connecting axle 2 is blocked, and with stop pad and bolt 6 jam plate 5 is fixed on the back timber 3, makes back timber 3 swing certain angle relatively around connecting axle about 2.The Connection Block 1 of cross syndeton 10 other ends is hinged by pin-and-hole 12 with caving shield 4 usefulness bearing pins 7, and baffle plate 8 blocks bearing pin 7, with lock pin and D shape card 9 fixed dams 8, makes back timber 3 swing up and down certain angle around bearing pin 7.
The above only is that preferred implementation of the present utility model is described; should be understood that; because the finiteness of literal expression; and objectively have unlimited concrete structure; for those skilled in the art; under the prerequisite that does not break away from the utility model principle, can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
