Abstract
The utility model relates to a turning device, aims to provide a firm and wear-resistant rotary table, and discloses a rotary table of a tunneling machine. The rotary table of the tunneling machine comprises a rotary table body, four rotary oil cylinder pin shaft holes and two working arm pin shaft holes are formed on the rotary table body, two of the four oil cylinder pin shaft holes are formed in the upper end surface of the rotary table body, and the other two are formed in the front end surface of the rotary table body; the two working arm pin shaft holes are formed in the front end surface of the rotary table body and above the two oil cylinder pin shaft holes formed on the front end surface of the rotary table body, and alloy steel sleeves are embedded in the four oil cylinder pin shaft holes and the two working arm pin shaft holes; and a self-lubricating bushing is embedded in each alloy steel sleeve. The rotary table of the tunneling machine has the advantages that the working arm pin shaft holes and the oil cylinder pin shaft holes, which are easy to be abraded, are embedded with alloy steel sleeves and self-lubricating bushings, the wearing resistance is improved, and the maintenance frequency is reduced.
Description
Technical field
The utility model relates to a kind of coal mine machinery, particularly relates to a kind of development machine.
Background technology
Development along with the China's coal-mine industry, power requirement to development machine is increasing, yet the development machine that power is larger, working strength is higher, especially panoramic table easily causes bearing pin wearing and tearing body, working arm pin shaft hole, oil cylinder pin shaft hole, wearing and tearing oil cylinder bearing pin, working arm bearing pin, increase cost of production, affect production efficiency.
The utility model content
The technical problems to be solved in the utility model provides a kind of solid wear-resisting panoramic table.
The utility model development machine panoramic table comprises the panoramic table body, four oil cylinder pin shaft holes and two working arm pin shaft holes are set on the described panoramic table body, two are arranged on described panoramic table body upper surface in described four oil cylinder pin shaft holes, two are arranged on described panoramic table body front end face, described two working arm pin shaft holes are arranged on described panoramic table body front end face, described two working arm pin shaft holes are above two described oil cylinder pin shaft holes that described panoramic table body front end face arranges, all be set with the alloy steel bushing in described four oil cylinder pin shaft holes and two working arm pin shaft holes, all be set with self-lubricating bushing in all described alloy steel bushings.
Compared with prior art, the utility model has been set with alloy steel bushing and self-lubricating bushing in working arm pin shaft hole that panoramic table the most easily weares and teares and oil cylinder pin shaft hole, strengthened abrasion resistance, has reduced the maintenance frequency of panoramic table.
Below in conjunction with accompanying drawing the utility model development machine panoramic table is described further.
Description of drawings
Fig. 1 is the utility model development machine panoramic table top view;
Fig. 2 is the utility model development machine panoramic table front view.
The specific embodiment
As shown in Figures 1 and 2, the utility model development machine panoramic table comprises panoramic table body 1, four oil cylinder pin shaft holes 3 and two working arm pin shaft holes 2 are set on the panoramic table body 1, two are arranged on panoramic table body 1 upper surface in four oil cylinder pin-and-holes 3, two are arranged on panoramic table body 1 front end face, two working arm pin shaft holes 2 are arranged on two oil cylinder pin shaft hole 3 tops of panoramic table body 1 front end face, are set with alloy steel bushing 4 and self-lubricating bushing 5 in four oil cylinder pin shaft holes 3 and two working arm pin shaft holes 2.
Above-described embodiment is described preferred embodiment of the present utility model; be not that scope of the present utility model is limited; under the prerequisite that does not break away from the utility model design spirit; various distortion and improvement that those of ordinary skills make the technical solution of the utility model all should fall in the definite protection domain of the utility model claims.
