After the heading machine works for a period of time, the heading machine needs to be overhauled according to corresponding overhauling rules, wherein the overhauling of the slewing support is an important overhauling project. The inner ring of the slewing support of the heading machine is a large-sized bearing with larger diameter, the outer ring of the inner ring is connected with the heading machine body through a wire hole on the outer ring, the inner ring is connected with the slewing table of the heading machine through a wire hole on the inner ring, the slewing support of the heading machine needs to be overhauled in time after being used for a certain time, however, in the process of overhauling and hoisting the slewing support at present, the slewing support is hoisted only through a chain matched with a pull ring and other parts, and a certain safety risk exists, so the utility model provides the slewing support hoisting and overhauling device of the heading machine.

Disclosure of Invention

Aiming at the situation, in order to overcome the defects of the prior art, the utility model provides a development machine maintenance device, which comprises ten rods integrally formed by four horizontal rods, wherein the upper ends of the four horizontal rods are respectively provided with a through groove arranged along the length direction of the horizontal rods, each through groove is slidably clamped with a roller along the length direction of the through groove, the upper end and the lower end of each roller are coaxially and fixedly connected with chucks which are movably matched with the end surfaces of the horizontal rods, each roller is coaxially provided with a vertically arranged through hole, the inner wall of each through hole is coaxially and movably inserted with a vertical rod, the upper end of each vertical rod is coaxially and fixedly connected with a hexagonal nut, the lower side of the outer edge of each vertical rod is coaxially and fixedly connected with a baffle, the outer edge of each vertical rod is provided with threads positioned below the baffle, the upper end of each ten rod is coaxially and fixedly connected with a support column, and the upper end of each support column is coaxially and fixedly connected with a hanging ring.

Preferably, washers are fixedly connected coaxially with the chucks at the upper ends of the rollers.

Preferably, the outer edge of the supporting column is fixedly connected with the upper ends of four pull rods uniformly distributed around the axis of the supporting column, and the lower ends of the four pull rods are in one-to-one correspondence with the tail ends of the four horizontal rods and are fixedly connected with the tail ends of the four horizontal rods.

The utility model has the beneficial effects that:

1. the utility model has simple structure, convenient operation and strong practicability, can fixedly connect the rotary support of the heading machine, and can hoist by connecting the hanging ring with an external hoisting device, thereby having high safety.

2. Because the outer ring and the inner ring of the rotary support are uniformly provided with a plurality of screw holes around the axis, when the rotary support is used, the screw threads on the lower side of the vertical rod can be matched and connected with the screw holes on the inner ring or the outer ring of the rotary support, so that the vertical rod is connected with the rotary support, the connection is stable, and the lifting maintenance of the rotary support is facilitated.

Detailed Description

The following describes embodiments of the present utility model in further detail with reference to figures 1-3.

The first embodiment solves the technical scheme that the utility model has simple structure, convenient operation and strong practicability, can fixedly connect the slewing support of the heading machine, and can hoist through connecting the hitching ring 11 with an external hoisting device, thereby having high safety. Because the outer ring and the inner ring of the rotary support are uniformly distributed with a plurality of screw holes around the axis of the outer ring and the inner ring, when the rotary support is used, the screw thread 9 on the lower side of the vertical rod 6 can be matched and connected with the screw thread 9 on the inner ring or the outer ring of the rotary support, so that the vertical rod 6 is connected with the rotary support, the connection is stable, and the lifting maintenance of the rotary support is facilitated.

According to the second embodiment, on the basis of the first embodiment, the ten-piece rod 14 is composed of four horizontal rods 1 which are uniformly distributed in a surrounding manner, the roller 3 is movably clamped in the through groove 2 on each horizontal rod 1, the chucks 4 at the upper end and the lower end of the roller 3 are respectively in contact fit with the upper end and the lower end of the horizontal rod 1, the roller 3 is further limited in the through groove 2, the vertical rod 6 is movably inserted in the through hole 5 on the roller 3, the vertical rod 6 can move vertically along the roller 3, the vertical rod 6 can rotate in the through hole 5, the roller 3 can move reversely in the through groove 2 along the length of the through groove 2, the vertical rod 6 can move along with the roller 3 in the length direction of the through groove 2, the vertical rod 6 has a certain degree of freedom, flexible position adjustment can be performed in space, the four vertical rods 6 are in one-to-one correspondence with four wire holes distributed in the inner ring (or the outer ring) of the rotary support, then the threads 9 on the vertical rod 6 are connected with the corresponding holes, namely, the vertical rod 6 can be screwed into the corresponding holes through the threads 9, the inner hole 6 is screwed into the hole of the rotary support 6, the inner hole 8 is in the rotary support ring is screwed into the corresponding hole, the hole is in the threaded hole is screwed up to the corresponding hole, the hole is screwed up to the inner ring is screwed up with the corresponding hole, and the end face of the rotary support ring is connected with the rotary support ring 6, and the rotary support ring is slowly, and the rotary ring is screwed down with the rotary ring is screwed down, and is connected with the rotary ring, and the rotary ring is convenient for the machine, and has a lifting device. The inner edge of the washer 12 does not affect the vertical movement of the vertical rod 6. The pull rod 13 can increase the structural strength of the utility model.
