Abstract
The utility model discloses a round pin is arranged pin and is prevented scurrying device, including the baffle, be provided with pin fixing device on the baffle working face, pin fixing device is close to the edge of baffle working face, and the pin is installed in pin fixing device. The utility model discloses an arrange with the round pin that baffle and pin fixing device will be independent that the pin is fixed be in the same place, the effectual equipment operation in -process that has prevented is owing to reasons such as wearing and tearing, vibrations lead to the increase of pegging hole gap, causes to sell that row's pin is scurried out, the coal machine falls, and then brings the problem of production safety hidden danger.
Description
Technical field
The utility model belongs to conveying arrangement technical field, relates to a kind of pin row pin leap-preventing device.
Background technique
Tooth bar in combined mechanization mining face conveyor is used for the walking of coal machine, and be fixedly connected with by two pin row pins between tooth bar with transport airplane, pin row pin is fixed by L-type pin.In actual production, owing to wearing and tearing, shaking, checking, the reason such as not in place often can cause pin attachment hole gap to increase, and pin row pin is scurried out.So just there will be coal machine to slide down, damage the problems such as coal machine, have a strong impact on safety in production, cause economic loss.Colleague too increases the workload of coal machine overhauling work, indirectly increases the potential safety hazard of coal machine overhauling work.
Model utility content
The purpose of this utility model is to provide a kind of pin row pin leap-preventing device, solves pin row pin on existing combined mechanization mining face conveyor and easily scurries out, there is the problem of production safety hidden danger.
The technological scheme that the utility model adopts is, a kind of pin row pin leap-preventing device, comprises baffle plate, baffle plate working surface is provided with pin fixing device, and pin fixing device is near the edge of baffle plate working surface, and pin is installed in pin fixing device.
Feature of the present utility model is also,
Pin fixing device is provided with two, pin fixing device symmetry be arranged at the relative both sides of baffle plate working surface.
Baffle plate side is provided with " recessed " shape opening.
Opening is positioned at the side perpendicular with pin fixing device place side.
Pin is screw, and pin fixing device is the nut adapted with pin.
The beneficial effects of the utility model are, pin row pin leap-preventing device will be by will independently be fixed together baffle plate and pin fixing device by pin row pin, effectively prevent in equipment running process because the reasons such as wearing and tearing, vibrations cause pin attachment hole gap to increase, cause that pin row pin is scurried out, coal machine slides down, and then bring the problem of production safety hidden danger.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of pin row pin of the utility model leap-preventing device.
In figure, 1. baffle plate, 2. opening, 3. pin, 4. pin fixing device.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
The structure of a kind of pin row pin of the utility model leap-preventing device as shown in Figure 1, comprises baffle plate 1, and baffle plate 1 working surface is provided with pin fixing device 4, and pin fixing device 4 is near the edge of baffle plate 1 working surface, and pin 3 is installed in pin fixing device 4.
Wherein pin fixing device 4 is provided with two, pin fixing device 4 symmetry be arranged at the relative both sides of baffle plate 1 working surface; Baffle plate 1 side is provided with " recessed " shape opening 2; Opening 2 is positioned at the side perpendicular with pin fixing device 4 place side; Pin 3 is screw, and pin fixing device 4 is the nut adapted with pin 3.
During use, transport airplane pin row pin leap-preventing device is put into the connecting groove of tooth bar and transport airplane, by pin fixing device 4 row of aligning pin connection mouth, pin 3 distribution fixing device 4 is inserted (being screwed into) connection mouth, namely completes the connection of tooth bar and transport airplane.
The setting of opening 2, its " recessed " shape is designed: on the one hand, adapt, be convenient to leap-preventing device and put into the projection shape in connecting groove; Make leap-preventing device and connecting groove have a fixed gap on the other hand, be convenient to pin 3 and enter pin fixing device 4.
The utility model will be by will independently be fixed together baffle plate and pin fixing device by pin row pin, effectively prevent in equipment running process because the reasons such as wearing and tearing, vibrations cause pin attachment hole gap to increase, cause that pin row pin is scurried out, coal machine slides down, and then bring the problem of production safety hidden danger.
