Detailed Description
The invention is further illustrated below with reference to the figures and examples. In the following detailed description, exemplary embodiments of the invention are described by way of illustration only. Needless to say, a person skilled in the art realizes that the described embodiments can be modified in various different ways without departing from the spirit and scope of the present invention. Accordingly, the drawings and description are illustrative in nature and not intended to limit the scope of the claims.
As shown in fig. 1 to 11, the two-way up-and-down opening-closing type trailer carriage comprises a floor plate 1 and baffle posts 11 fixedly arranged at four corners of the floor plate 1 respectively, wherein the four baffle posts 11 are well known and are generally welded on the floor plate 1.
A compartment baffle 2 is arranged between two adjacent baffle columns 11, at least the compartment baffle 2 at the front end of the compartment bottom plate 1 is a fixed baffle 21, and the front end of the compartment bottom plate 1 is a tractor position and does not need to be opened, so that the front end is the fixed baffle 21.
At least one of the compartment baffles 2 at the two sides and the rear end of the compartment bottom plate 1 is a bidirectional opening and closing baffle 22, and when the bidirectional opening and closing baffle 22 is used for loading and unloading materials, the compartment baffles 2 can be opened upwards or downwards according to actual conditions. Most preferably, the compartment barriers 2 on both sides and at the rear end of the floor panel 1 are the two-way opening and closing barriers 22, so that three of the two-way opening and closing barriers 22 can be opened downwards according to the loading and unloading requirements of the packaged goods, and can also be determined according to the orientation when the bulk goods are unloaded, and which one of the two-way opening and closing barriers 22 is opened upwards can be determined, for example, when the bulk goods are unloaded from the left side, only the left-side two-way opening and closing barrier 22 can be opened upwards. It should be noted that, in the present embodiment, "front", "rear", "left" and "rear" are referred to with respect to the traveling direction of the tractor in practical application. Of course, the present embodiment can also be designed as the bidirectional opening and closing baffle 22 only for one or two of the three compartment baffles 2 at the two sides and the rear end according to the common dumping side, and the remaining compartment baffles 2 at the two sides and the rear end are designed to be opened upwards, opened downwards or fixedly arranged, and the like, and these solutions should also be within the protection scope.
The bottom of the bidirectional opening and closing baffle plate 22 is provided with at least two lower pin connecting lugs 31 extending to the side surface of the compartment bottom plate 1, the side surface of the compartment bottom plate 1 is provided with lower pin hinge lugs 32 corresponding to the lower pin connecting lugs 31, and lower hinge pins 33 are detachably mounted between the lower pin connecting lugs 31 and the corresponding lower pin hinge lugs 32. When the lower hinge pin 33 is installed, it can be used as a hinge pin for opening the bidirectional opening and closing baffle 22 downwards, or fix the bidirectional opening and closing baffle 22 together with the hinge structure on the upper part of the bidirectional opening and closing baffle 22; when the two-way opening and closing baffle 22 is detached, the bottom of the two-way opening and closing baffle 22 can be released from being fixed, and the two-way opening and closing baffle 22 can be opened upwards conveniently.
Since the upward opening of the bi-directional opening and closing baffle 22 of the present embodiment is mainly directed to the dumping of the bulk cargo, when transporting the bulk cargo such as coal, sand, stone, etc., the bottom of the bi-directional opening and closing baffle 22 is subjected to a much larger cargo pressure than the top, and the pressure can significantly press the bottom of the bi-directional opening and closing baffle 22 outward, so that the lower hinge pin 33 is respectively clamped between the lower pin connecting lug 31 and the lower pin hinge lug 32 and is not easily taken out. In order to solve the above problem, a baffle bottom outward-extrusion limiting device is arranged between the compartment bottom plate 1 and the bidirectional opening and closing baffle 22 in this embodiment.
As shown in fig. 5, fig. 7, fig. 8 and fig. 11, the outer limit device that extrudes at the bottom of the baffle is including fixed setting up on the hinge ear 32 of lower round pin and extending the outer limit ear 34 that extrudes of the bottom department of two-way retractable baffle 22, outer limit ear 34 with be equipped with outer limit clearance 35 that extrudes between the bottom of two-way retractable baffle 22, the bottom of two-way retractable baffle 22 be equipped with the hinge ear that outer limit ear 34 corresponds dodges mouth 36, the bottom of two-way retractable baffle 22 is rotated and is installed and to be blocked to the outer limit backing plate 37 that extrudes of outer limit clearance 35 department. When the outer extrusion limiting cushion plate 37 rotates to the outer extrusion limiting gap 35, the outer extrusion limiting cushion plate 37 takes the outer extrusion limiting lug 34 as a supporting point to extrude the bottom of the bidirectional opening and closing baffle 22 inwards, so that the outer extrusion effect of bulk goods on the bottom of the bidirectional opening and closing baffle 22 can be obviously reduced, and the lower hinge pin 33 is small in clamping effect and can be taken out conveniently. When needing to open two-way baffle 22 that opens and shuts, will outer crowded spacing backing plate 37 rotates and breaks away from outer crowded spacing clearance 35 department can, the setting that the mouth 36 was dodged to the articulated ear can avoid outer crowded spacing ear 34 is right the hindrance when two-way baffle 22 that opens and shuts.

The bottom of the bidirectional opening and closing baffle 22 is provided with a pad limiting bulge 38 for preventing the outward extrusion limiting pad 37 from rotating downwards. When the outward extrusion limiting cushion plate 37 is operated to be separated from the outward extrusion limiting gap 35, the outward extrusion limiting cushion plate 37 is rotatably mounted, so that the position of the outward extrusion limiting cushion plate after being separated from the outward extrusion limiting gap 35 is not easy to control, the outward extrusion limiting cushion plate 37 can freely hang down due to self weight in a conventional situation, and when the bidirectional opening and closing baffle plate 22 is opened downwards, the outward extrusion limiting cushion plate 37 is particularly easy to interfere with the side surface of the compartment bottom plate 1, so that the structural damage is caused. The pad limiting protrusion 38 can limit the outward pressing limiting pad 37, so that the downward opening of the bidirectional opening and closing baffle 22 is not influenced by the excessive free falling. The pad plate limiting protrusion 38 may be a bolt, a stopper, or a rivet fixedly disposed on the bidirectional opening/closing baffle 22.
The structure of the baffle bottom external extrusion limiting device is directly provided with the external extrusion limiting lug 34 on the lower pin hinge lug 32, and belongs to the preferred scheme of simplifying the overall structure in the embodiment. Besides, the baffle bottom outward extrusion limiting device can be arranged outside the lower pin hinging lug 32, and the schemes that the baffle bottom outward extrusion limiting device can extrude the bottom of the bidirectional opening and closing baffle 22 when limiting is performed and the bidirectional opening and closing baffle 22 is not influenced to be opened when releasing are all within the protection range.
