Description
Technical field
This utility model relates to the self-locking device at a kind of coal mine explosion-proof diesel engine transport vehicle carriage back door.
Background technology
At present, the self-locking device of domestic anti-explosion diesel engine transport vehicle is that spring is arranged on pull bar, drives fixation hook with pull bar, it is achieved lock, open, and this device also exists following shortcoming: the difficulty that (1) regulates locking is big. (2) owing to back door often contacts with the thing such as stone, after vehicle uses a period of time, causing that back door deforms, self-locking device will exist does not open, and fits badly, not tight. (3) inconvenience is installed, adjusts setting angle difficulty, slightly error, arise that the phenomenon of not tight. (4) owing to handling goods is frequent, spring reduces service life, is approximately in 3-6 month and will change spring once.
Summary of the invention
This utility model overcomes weak point of the prior art, it is provided that a kind of anti-explosion diesel engine transport vehicle carriage rear door locking device, and this device will cause carriage back door not open because of deformation or displacement, fits badly, not tight, the difficult problem repaired.
In order to realize the purpose of this utility model, we will adopt the following technical scheme that and be practiced:
A kind of coal mine explosion-proof diesel engine self-discharging transporter self-locking device, including Rear frame and compartment, Rear frame is provided with self-discharging carriage, it is characterized in that: described self-discharging carriage base plate rear end bottom is provided with upper mounted plate, the rear portion of upper mounted plate bottom is provided with latch hook, and the top of latch hook is taken in the bottom at self-discharging carriage back door; Described Rear frame is provided with bottom plate near the position of Rear frame afterbody, and the bottom of bottom plate is provided with bottom base, and bottom base is fixed by nut and latch hook connecting rod, and latch hook connecting rod is connected with latch hook by pitch chain.
Further, the central axis of the latch hook connecting rod that the vertical centrage of described latch hook and bottom base are installed by nut is in the same plane.
Further, the bottom of described latch hook is installed on by bearing pin, split pin and packing ring in the pin shaft hole of the bottom of upper mounted plate.
Further, the upper end of described pitch chain is installed on by bearing pin, split pin and packing ring in the pin shaft hole at the middle part of latch hook.
Further, the lower end of described short link is installed in the pin shaft hole in latch hook connecting rod by bearing pin, split pin and packing ring.
Beneficial effect
Improve quality, precision and efficiency, save raw material, facilitate processing, make and install, the simplicity of use.
