Detailed Description
The utility model is described in detail below with reference to the figures and the embodiments. It should be understood that the detailed description and specific examples, while indicating the present invention, are given by way of illustration and explanation only, not limitation.
Referring to fig. 1-2, a quick release pallet fork 100 for use in a nuclear environment of the present invention is shown, comprising a pallet fork 10 and a fixed attachment bracket 30. Wherein the fixed link 30 is disposed below the fork 10.
As shown in fig. 3, quick mounting means 40 for quickly mounting or dismounting the fork 10 to or from the fixed link 30 are provided at the connection portions of both ends of the fork 10 and the fixed link 30, respectively, in the direction along the longitudinal center axis of the fork 10.
Fig. 4 shows a specific structure of the quick-mounting device 40. Quick-mount device 40 includes a mounting bracket 41, a pin 42, and an adjustment assembly 43. The mounting bracket 41 is disposed on the fixed connecting frame 30 and has a mounting pin hole 411. A pin 42 is provided on the pallet fork 10 which mates with a mounting pin hole 411 on the mounting bracket 41. When the pin 42 is inserted into the mounting pin hole 411, the fork 10 is attached to the fixed link 30, and when the pin 42 is withdrawn from the mounting pin hole 411, the fork 10 is detached from the fixed link 30. An adjustment assembly 43 is provided on the fork 10 for adjusting the pin 42 so that the pin 42 can be quickly inserted into or withdrawn from the mounting pin hole 411.
Specifically, two lower fork plates 11 are arranged below the pallet fork 10, and the two lower fork plates 11 are arranged in parallel. The adjustment assembly 43 includes an unlocking pressure plate 431, two parallel arranged unlocking links 432, a push plate 433, a compression spring 434 and an end shaft cover plate 435. The two unlocking links 432 pass through one of the two lower fork plates 11 and are respectively fixed at one end to the unlocking pressure plate 431 and at the other end to the pushing plate 433. The pin shaft 42 passes through the pushing plate 433 and is fixedly connected with the pushing plate, one end of the pin shaft passes through one of the two lower fork plates 11 to be matched with the mounting frame 41, and the other end of the pin shaft passes through the other of the two lower fork plates 11 and the end shaft cover plate 435. The compression spring 434 is sleeved on the pin 42 and has one end connected to the pushing plate 433 and the other end connected to the end shaft cover plate 435. An end axle cover plate 435 is secured to the other of the two lower fork plates 11. When the pallet fork 10 needs to be disassembled, the unlocking pressing plate 431 is pressed to overcome the elastic force of the compression spring 434, and the control pin shaft 42 axially moves and retreats from the mounting pin hole 411. The fork 10 is then lifted off the fixed link 30 and the release pressure plate 431 is released and the release pressure plate 431 returns to its original position under the force of the compression spring 434, at which point the removal of the fork 10 is completed. When it is desired to install the pallet fork 10, the unlocking pressure plate 431 is pressed to contract against the elastic force of the compression spring 434. After the fork 10 is mounted in place, the unlocking pressing plate 431 is released, and the pin shaft 42 is inserted into the mounting pin hole 411 by the elastic force of the compression spring 434, so that the fork 10 is mounted to the fixed link 30.
As a preferred embodiment, one end of the unlocking link 432 connected to the unlocking pressing plate 431 is provided with a first limiting groove 436. The adjustment assembly 43 further includes two limiting blocks 437 respectively engaged with the first limiting grooves 436. Both stopper blocks 437 are fixed to the unlocking pressure plate 431 by screws. The unlocking link 432 can be quickly positioned to the unlocking pressure plate 431 by the first stopper groove 436 and the stopper 437.
The part of the unlocking connecting rod 432 connected with the pushing plate 433 is provided with a second limiting groove 441. A third limiting groove 438 is formed at the connecting part of the pin shaft 42 and the pushing plate 433. The adjustment assembly 43 further includes a stop bar 439 that cooperates with the second and third stop grooves 441, 438, respectively. The stopper 439 is fixed to the push plate 433 by a screw. The pushing plate 433 is further provided with a limiting claw 440 for sliding and driving the limiting bar 439. The stopping pawl 440 forms a guide channel together with the second stopping groove 441 and the third stopping groove 438 for guiding the stopping bar 439. When the unlocking link 432 and the pin shaft 42 are mounted to the push plate 433, the unlocking link 432 and the pin shaft 42 are inserted into the push plate 433 in advance to a predetermined position, and then the stopper 439 is inserted along the guide passage and fixed by a screw, thereby rapidly fixing the unlocking link 432 and the pin shaft 42 to the push plate 433.
As a preferred embodiment, two mounting brackets 41 corresponding to the two quick mounting devices 40 located at both ends of the fork 10 are respectively provided at both sides of the fixed connection frame 30. In this way, the forces are evenly balanced between the forks 10 and the fixed link 30.
As shown in fig. 4, two quick mounting devices 40 are provided at both ends of the fork 10, and the two quick mounting devices 40 at the same end of the fork 10 are arranged in sequence in the direction of the longitudinal center axis of the fork 10. Two mounting brackets 41 corresponding to the two quick mounting devices 40 provided at the same end of the fork 10 are provided at both sides of the fixed link 30, respectively. It will be appreciated that the fork 10 is of a relatively long length and the two quick mount devices 40 are not able to stably mount the fork 10 to the fixed link frame 30. Therefore, in order to make the connection between the fork 10 and the fixed link 30 more stable, two quick-mounting devices 40 are provided at each end of the fork 10, and the two quick-mounting devices 40 are distributed on both sides of the fork 10 to improve the stability of the force.
As a preferred embodiment, the quick release pallet fork 100 that can be used in a nuclear environment is further provided with a gearbox 20, the gearbox 20 being disposed between the pallet fork 10 and the fixed attachment frame 30 and being connected at one end to the pallet fork 10 and at the other end to the fixed attachment frame 30. The fixed link frame 30 is provided with an accommodating space 32 for accommodating the gear case 20, and the gear case 20 is fixedly connected to the fixed link frame 30.
As a preferred embodiment, the end axle cover plate 435 is fixed to the outside of the other of the two lower fork plates 11. The end shaft cover plate 435 is fixed on the outside to facilitate installation. Alternatively, the end shaft cover plate can also be fixed on the outer side of the other of the two lower fork plates, i.e. between the two lower fork plates.
As a preferred embodiment, the fixed link frame 30 is provided at both ends thereof with guide positioners 31 for guiding the lower fork plate 11 of the fork 10, respectively.
It can be understood that when the fork 10 is installed, the pin shaft 42 needs to be accurately inserted and aligned to the installation pin hole 411, and the position between the fork 10 and the fixed connecting frame 30 can be quickly located through the guiding of the guiding locating piece 31, so that the alignment work of the pin shaft 42 and the installation pin hole 411 is completed.
The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It should be understood by those skilled in the art that the above embodiments do not limit the present invention in any way, and all technical solutions obtained by using equivalent alternatives or equivalent variations fall within the scope of the present invention.
