Abstract
The utility model discloses a digger with a hydraulic pressure support, comprising a platform, of which a side wall is arranged for supporting the digger on an underground tunnel. The utility model has the advantages that the digger has good stability and high production efficiency in the small-sized coal mine underground operation.
Description
(1) technical field
The utility model relates to a kind of mining machinery that is applicable to middle and small scale coal mine underground work, particularly a kind of digger that has the hydraulic pressure support.
(2) background technology
Digger in middle and small scale coal mine underground work has following defective at present: because complete machine is in light weight, in the time of production operation, stability is poor.Especially side direction and downwards mining work the time, complete machine does not have the strong point, because complete machine is subjected to very big side direction or the machine shifted laterally occurs during the reaction force that makes progress or tilt upward, production efficiency reduces greatly.
(3) summary of the invention
The technical problems to be solved in the utility model is: a kind of digger that hydraulic pressure supports that has is provided, makes the good stability of when mining work digger.
In order to solve the problems of the technologies described above, the utility model comprises platform, the sidewall and the hydraulic pressure on the roof that make machine be supported on the tunnel, down-hole is installed on the described platform supports.
Described hydraulic pressure supports and comprises that two hydraulic pressure sides support and a hydraulic pressure top is supported, and two hydraulic pressure sides support and are installed in platform front end both sides respectively, and the upper front end that is installed in platform is supported on the hydraulic pressure top.
Described hydraulic pressure side supports and the support of hydraulic pressure top is hydraulic jack.
The control hydraulic pressure side that includes the utility model supports and flexible control stick is supported on the hydraulic pressure top.
The beneficial effects of the utility model are that the utility model makes the digger good stability in middle and small scale coal mine underground work, enhances productivity.
(4) description of drawings
Fig. 1 is a structural representation of the present utility model;
Among the figure: 1. the hydraulic pressure top is supported, and 2. the hydraulic pressure side supports, 3. platform, 4. control stick.
(5) specific embodiment
A kind of specific embodiment is as shown in Figure 1 installed the hydraulic pressure side in the platform 3 front end both sides of machine and is supported one of 2, one side, in platform 3 upper front end a hydraulic pressure top is installed and supports 1, and these two kinds of supports are exactly hydraulic jack, by hydraulic-driven.The support 2 of hydraulic pressure sides controlled by control stick 4 on operating machine or hydraulic pressure pushes up the flexible of support 1, makes support 2 of hydraulic pressure side or hydraulic pressure push up two side and the roof that support 1 withstands on cross section, tunnel, down-hole securely.Like this, machine in mining work, even be subjected to very big lateral force or during the reaction force that makes progress, can lean on the hydraulic pressure side support 2 and the hydraulic pressure top support 1 and make machine stable, increase work efficiency.
Claims (4)
1. one kind has the digger that hydraulic pressure supports, and comprises platform (3), it is characterized in that: the sidewall and the hydraulic pressure on the roof that make machine be supported on the tunnel, down-hole are installed on the described platform (3) support.
2. the digger that has the hydraulic pressure support according to claim 1, it is characterized in that: described hydraulic pressure supports and comprises that two hydraulic pressure sides support (2) and (1) is supported on a hydraulic pressure top, two hydraulic pressure sides support (2) and are installed in platform (3) front end both sides respectively, and the upper front end that (1) is installed in platform (3) is supported on the hydraulic pressure top.
3. the digger that has the hydraulic pressure support according to claim 2 is characterized in that: described hydraulic pressure side supports (2) and hydraulic pressure top support (1) is hydraulic jack.
4. the digger that has the hydraulic pressure support according to claim 3 is characterized in that: include control hydraulic pressure side support (2) and hydraulic pressure top and support control stick (4) that stretch (1).
